In this step, by setting the water pump 2 to connect the water storage tank 22 and the water injection pipe 23, the conveyed rubber products can be sprayed with water for cleaning, so as to reduce dust and rubber debris adhering to the surface of the products after pre-forming, so as to improve the cleanliness of their surface.

In this step, by setting the nozzle 7 and the spray hole 71 to connect the water outlet hole 24, the sprayed water can be dispersed to increase the spraying range of the water and make the contact with the rubber product more uniform, so as to improve the effect of cleaning the rubber product.

[0030] Reference Figure 2 As shown, the side wall of the limiting plate 62 is fixedly connected with a rubber pad 8; the rubber pad 8 is arranged on both sides of the universal wheel 52; during operation, when the limiting plate 62 clamps and fixes the universal wheel 52, the rubber pad 8 will contact the side wall of the universal wheel 52.

[0031] Working principle: When weighing rubber products, place the rubber products on the surface of the conveyor 1 on one side, and then the conveyor 1 transports the rubber products to the surface of the weighing platform 11. At this time, the products can be weighed, and the qualified products are transported out from the conveyor 1 on the other side. When the weight exceeds the qualified weight, the hydraulic rod 12 on one side is controlled to lift the weighing platform 11, so that the heavier unqualified products are removed from the surface of the weighing platform 11. When the weight is lighter, the hydraulic rod 12 on the other side is activated to lift the weighing platform 11, and the lighter unqualified products are removed from the weighing platform 11. Qualified products are removed from the surface of the weighing platform 11. When qualified rubber products are transported from the surface of the conveyor 1, water is injected into the water pump 2 from the water injection pipe 23, and then the water pump 2 is started to pump water from the water storage tank 22, and then the water is sprayed onto the surface of the rubber products from the multiple water outlet holes 24 at the water outlet pipe 21 to clean them. The cleaned water will fall from the gap between the conveyors 1, and then fall into the collection box 3 below to be collected, and then the water will enter the water storage tank 22 again from the connecting pipe 31. When the water enters the collection box 3, it will pass through the filter screen 42, at this time, the filter screen 42 can filter the water passing through and filter out impurities in the water. When the filtering is completed, the filter screen 42 is pulled out and cleaned and then installed and reset. The collection vehicle 51 is pushed to the side of the weighing platform 11. At this time, the universal wheel 52 is aligned with the limiting groove 5. When the universal wheel 52 enters the limiting groove 5, its position will be restricted. Then the collection vehicle 51 can collect the unqualified products that have escaped from the surface of the weighing platform 11 separately. When the universal wheel 52 enters the limiting groove 5, the side of the universal wheel 52 The surface will contact with the limiting plate 62. When the universal wheel 52 continues to move, it will squeeze the limiting plate 62. At this time, the second fixing plate 6 can shrink and generate a rebound force. When the collection vehicle 51 moves well, the limiting plate 62 can clamp and fix the universal wheel 52. When water is sprayed from the water outlet 24, it will pass through the nozzle 7 and the spray hole 71. At this time, the nozzle 7 and the spray hole 71 can disperse the water, so that the contact surface between water and the rubber product is wider. When the limiting plate 62 clamps and fixes the universal wheel 52, the rubber pad 8 will contact the side wall of the universal wheel 52.

[0032] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
