Description

System and method for processing defective products in polyurethane tire development and production

Technical Field

The invention relates to the technical field of polyurethane tire production, in particular to a system and a method for processing defective products in polyurethane tire development and production.

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 tyre removing device 4 comprises a base 41, extension plates 42 and a tyre ejecting member 43, wherein the extension plates 42 are symmetrically fixed on the outer peripheral wall of the base 41 in a cross manner, one extension plate 42 is closely adjacent to the conveying belt 31 and aligned with the central position of the conveying belt 31, and the wheels regulated by the centering device 32 are firstly received by the extension plates 42 and then gradually pushed by the conveying belt 31 until being completely placed on the tyre removing device 4.

A tread element 43 is mounted between each two adjacent extension plates 42. The tire ejection member 43 comprises a hydraulic ejector rod 431, a tire supporting head 432 and a positioning rod 433, wherein the hydraulic ejector rod 431 is vertically installed, the bottom end of the hydraulic ejector rod 431 is placed on the flat table 6, one end of the positioning rod 433 is installed on the outer peripheral surface of the base table 41, the other end of the positioning rod 433 is connected with the hydraulic ejector rod 431, a straight line where the extending direction of the positioning rod 433 is located penetrates through the central shaft of the base table 41, the positioning rod 433 is vertical to the hydraulic ejector rod 431, and the positioning rod 433 can stretch and retract to enable the hydraulic ejector rod 431 to be close to or far away from the base table 41.

Each hydraulic ram 431 can synchronously jack up the tire supporting head 432 at the upper end of each hydraulic ram, and the jacked tire supporting head 432 can uniformly apply force to the tire placed on the wheel on the tire removing device 4.

Because the diameter ranges of the wheels sorted by the sorting drums 21 at different heights are different, the smallest circular ring diameter surrounded by the tire support head 432 is the same as the smallest circular ring diameter of the wheel sorted by the sorting drum 21 corresponding to the smallest circular ring diameter, and the positioning rod 433 can drive the hydraulic ejector rod 431 to move away from the base 41, so that the circular ring diameter surrounded by the tire support head 432 is the same as the largest circular ring diameter of the wheel sorted by the sorting drum 21.
