The Air Expansion Shaft Automatic Winding Device Works More Efficiently

In the prior art, the two ends of the wound polymer coil are not neat, and the two ends of the coil are easily damaged by friction during the transportation process. On the other hand, because the roll is used for winding, when the coil is moved away from the roll, There is a large friction between the coil and the roller, so the removal speed is slow and the work efficiency is low.

In order to overcome the shortcomings of the prior art, the present utility model provides an automatic inflatable shaft winding device, which is provided with an inflatable shaft, and an external reel can be sleeved on the inflatable shaft, and then the external reel is used for winding After rewinding, the controller controls the air suction machine to draw air. The air pressure of the inflatable airbag is reduced, and the convex key can automatically retract into the slot hole, which is convenient to remove the inflatable shaft from the external reel. Volume efficiency is higher.

The technical solutions adopted by the utility model to solve its technical problems are:

An automatic inflatable shaft winding device, comprising a bracket, a drive motor, an air compressor, an air extractor, and an inflatable shaft erected on the bracket. One end of the inflatable shaft is drivingly connected with the driving motor, and the inflatable shaft The hollow shaft includes a hollow shaft, an inflatable air bag placed in the hollow shaft and a convex key. A plurality of slots are opened on the peripheral wall of the hollow shaft. The convex key is placed in the slot, and the convex key is used for When the inflatable airbag is inflated, the outer peripheral surface of the hollow shaft is ejected from the slot; an air pressure sensor is arranged in the inflatable airbag, and the air pressure sensor is electrically connected with the controller; both ends of the inflatable airbag Air nozzles are respectively provided, one end of the air nozzle is connected to the air extractor, and the other end of the air nozzle is connected to the air compressor; the drive motor, the air extractor, and the air compressor are all electrically connected to the controller; the convex key An end close to the inflatable airbag is provided with a first arc-shaped abutting block; the first arc-shaped abutting block is convex toward the side close to the inflatable airbag in an arc shape; one end of the first arc-shaped abutting block is close to the notch A compression spring is connected, and the other end of the compression spring is connected to the inner wall of the hollow shaft.

In the above technical solution, after inserting the external reel for winding the material on the inflatable shaft, the controller controls the air compressor to inflate into the inflatable air bag, the inflatable air bag expands and enlarges, and the convex key is pressed along the slot hole. When the outer peripheral surface of the hollow shaft is ejected, the convex key can be pressed to the inner side of the external reel. The controller receives the air pressure data through the air pressure sensor and reaches a certain value to automatically stop the work of the air compressor; the convex key presses against the external reel The drum prevents the external drum from sliding left and right relative to the inflatable shaft, and the two ends of the rolled coil are more tidy; the controller controls the driving motor to rotate and then starts the winding. After the winding is completed, the controller controls the air extractor to pump Inflated, the inflatable airbag shrinks, the convex key can automatically retract into the slot under the force of the spring without the outward pressing force, and there is a gap between the inflatable shaft and the external drum, which can be easily The entire rolled-up material is moved away from the inflatable shaft; the first arc is arranged on the top, and it is convex to the side close to the inflatable airbag, so that the inflatable airbag expands and resists the convex key not easily damaged; this technical solution Not only makes the ends of the coil more tidy, but also improves the working efficiency of the winding, and the inflatable airbag is not easy to damage.

Preferably, it further comprises a winding thickness measuring device, the winding thickness measuring device includes an infrared sensor arranged on the support, and the infrared sensor is electrically connected to the controller. Infrared sensors are installed at both ends of the bracket. When the roll exceeds a certain thickness, the coil will cover the infrared sensor, so that the receiver at the other end cannot receive the signal. At this time, the controller can receive the data of the thickness of the coil. , So as to automatically stop the work of the drive motor and stop winding.

Preferably, the end of the protruding key away from the inflatable airbag is provided with a second arc-shaped abutting block adapted to the curvature of the contact surface of the inner wall of the outer paper tube. Increase the top area and improve friction.

Preferably, the slot hole near the edge of the notch at one end of the second arc-shaped abutting block is provided with a recess adapted to the shape, size and thickness of the second arc-shaped abutting block. After the inflatable airbag is contracted, the outer side of the inflatable shaft maintains a smooth structure, which is convenient to move away from the external roll.

Preferably, an end of the second arc-shaped abutment block close to the slot is connected with a tension spring, and the other end of the tension spring is connected in the recess. It is convenient for the convex key to retract automatically.

Preferably, the outer surface of the second arc-shaped abutting block is provided with tooth patterns. Increase the friction with the external reel.

The beneficial effect of the utility model is: an automatic inflatable shaft winding device of the utility model, after the external reel used for winding the coil is inserted on the inflatable shaft, the controller controls the air compressor to move When the inflatable airbag is inflated, the inflatable airbag expands and expands. The convex key is pushed out of the outer peripheral surface of the hollow shaft along the slot hole, and the convex key can be pushed to the inner side of the external drum. The controller receives the air pressure data through the air pressure sensor. When a certain value is reached, the work of the air compressor is automatically stopped; the convex key presses against the external reel so that the external reel will not slide left and right relative to the inflatable shaft, and the two ends of the rolled coil are more tidy; the controller controls the drive motor to rotate The rewinding starts. After the rewinding is completed, the controller controls the air extractor to pump air, and the inflatable airbag shrinks. The convex key can automatically retract into the slot under the force of the spring without the outward pressing force. There is a gap between the expansion shaft and the outer roll, so that the entire wound roll can be easily moved away from the expansion shaft; the first arc is set against the top, and it protrudes toward the side close to the inflatable airbag. The arc shape makes the inflatable airbag expand and resist the convex key and is not easily damaged; this technical solution not only makes the two ends of the coil more tidy, but also improves the working efficiency of winding, and the inflatable airbag is not easily damaged.
