Background
Polyurethane, which is known as polyurethane, is a high molecular compound. The hard polyurethane plastic has light weight, excellent sound insulation and heat insulation performance, chemical resistance, good electrical performance, easy processing and low water absorption, is an ideal material for manufacturing tires, and particularly can be widely used for the guide wheels of small-sized carriers such as hand carts, wheelchairs and the like.
When the polyurethane tire is developed and produced, a certain amount of defective products are generated, and the defective products are worn and aged without being used, so that the polyurethane tire can be continuously put into production after recovery treatment. Although a single polyurethane tire production line produces few defective products, large production plants often build multiple production lines to develop various polyurethane tires of different sizes.
The polyurethane tire is required to be wrapped on the hub after being produced, and defective products are often generated due to offset and breakage in the tire wrapping process. The detection device can remove defective tires with hubs on each production line and uniformly convey the defective tires to the recovery line, and after defective polyurethane tires with hubs of different sizes are collected, the defective polyurethane tires outside the hubs need to be separated from the hubs, so that subsequent processing work can be performed.
In the prior art, most of defective product processing devices use cutters to cut off polyurethane rims, the rims are separated from hubs, each cutter needs to move and adjust to the edges of the wheels when cutting one rim, and because the sizes of the recovered wheels are different, the cutters move very frequently, if the diameters of the front wheel and the rear wheel are different greatly, the adjusting time of the cutters is longer, and the recovery efficiency of the tires is greatly reduced.
Meanwhile, a large amount of scrap with reduced cost is generated when the tire is cut by using the cutter, and additional scrap treatment work is needed after the tire is recovered; as the service time increases, the blade edge of the cutter also becomes progressively dulled, so that regular replacement and maintenance of the cutter are also required, which also increases the maintenance cost of the recovery device and affects the recovery efficiency of the tire.
The polyurethane wheel used by the small-sized carrier guide wheel is mostly tightly wrapped outside the wheel hub, and the polyurethane wheel is combined with the wheel hub by means of adhesion force and friction force. If a strong thrust force is applied to the tire in the axial direction, the tire can be forcibly pushed away from the hub to be pulled out.

The rotating motor 442 is mounted at the upper end of the translation member 441, and can drive the screw sleeve 443 to axially rotate, the screw 444 is vertically inserted into the screw sleeve 443, the positioning head 445 is a quadrangular prism, the positioning head 445 is fixedly mounted at the upper end of the screw 444, and the side length of the positioning head 445 is the same as the width of the opening at the upper end of the cavity 401, so that the positioning head 445 and the screw 444 connected with the positioning head 445 are limited and cannot axially rotate. The screw 444 corresponds to the threads of the thread sleeve 443, and the rotating motor 442 drives the thread sleeve 443 to axially rotate, so that the screw 444 is driven to vertically move. The screw 444 moves downwards to enable the positioning head 445 to shrink into the cavity 401, the screw 444 moves upwards to enable the positioning head 445 to extend out of the cavity 401, and after the positioning head 445 extends out of the cavity 401, the translation piece 441 drives the positioning head 445 to move horizontally, the positioning head 445 can contact the peripheral surface of the wheel in the moving process, and the wheel is driven to move towards the central shaft of the base 41.
