Description

Rubber pad injection molding machine with waste recycling function Technical Field The invention relates to the technical field of injection molding machines, in particular to a rubber pad injection molding machine with a waste recycling function. Background In rubber pad injection molding production, the problems of mixing and blockage are always key problems puzzling the industry. When traditional rubber pad injection molding machine is in the compounding, be difficult to with raw materials and retrieve waste material homogeneous mixing, lead to rubber pad quality uneven, influence product performance and market competition. In addition, in the process of recycling the waste, the irregular shape and viscosity of the waste are extremely easy to cause blockage of a material conveying channel. Once the blockage occurs, a large amount of time and labor are consumed for dredging, production interruption is caused, production efficiency is reduced, and production cost is increased. Therefore, development of a rubber pad injection molding machine capable of solving the problems of uneven mixing and blockage and realizing efficient recycling of waste materials is urgent. The patent with the patent publication number of CN118269314A discloses an injection molding machine for recycling plastic waste, which comprises a machine body, a charging barrel, a feeding hopper, a rotating cover, a moving mechanism and a moving mechanism, wherein the charging barrel is arranged on the machine body, the feeding hopper is arranged on the charging barrel, the feeding box is fixedly connected with the feeding hopper, the hollow exhaust box is fixedly arranged on the charging barrel, the rotating cover is rotationally connected with the feeding box, both sides of the rotating cover are connected with iron blocks through hinging rods, the moving mechanism comprises a mounting block arranged on the machine body, a fixing plate is fixedly connected on the mounting block, and a sliding rod is connected on the fixing plate in a sliding manner. The gas in the charging barrel can be well discharged, so that the generation of paste spots caused by local overheat decomposition and coking of molten liquid can be prevented, the quality of subsequently formed plastic products is qualified, a large number of defective products are avoided, and the production yield of the plastic products is greatly improved. The prior art has the following defects: The raw materials and the recycled waste materials cannot be uniformly mixed and the flow rate is controlled, namely, in rubber pad injection molding production, the generation of runner solidification materials, flash edges, defective products and other waste materials is difficult to avoid, however, most of the existing rubber pad injection molding machines lack effective waste material mixing measures, so that the raw materials and the recycled waste materials are unevenly mixed, the waste materials or the raw materials in the local area of a rubber pad finished product are concentrated, the color and texture difference is obvious, meanwhile, the problem of flow rate control exists, the accumulation of the waste materials in the local area is caused by too fast feeding, the insufficient feeding is caused by too slow feeding, the quality and performance of the rubber pad are seriously influenced by the conditions, the indexes such as strength and elasticity of the rubber pad are unstable, the defective rate is increased, the production efficiency is reduced, the production cost is further increased, and the economic benefit and market competitiveness of enterprises are weakened. When rubber pad waste recycling is performed, the waste material is irregular in shape and has viscosity, a material conveying channel is easy to block, the existing equipment cannot perform self-adaptive blocking removal treatment on the blocked waste material flowing pipeline, when blocking occurs, the equipment cannot be perceived by itself, feeding interruption and production stagnation of an injection molding machine can be caused, operators consume a large amount of time to check blocking positions, even if blocking points are found, the operators can only manually dredge the blocking points, the production efficiency is greatly reduced, delivery period is delayed, in addition, the frequent manual blocking removal not only increases labor cost, but also can damage the equipment due to misoperation, and further increases maintenance cost. Disclosure of Invention In view of the problems that the raw materials and the recycled waste cannot be uniformly mixed, the flow rate is controlled, the blockage removal treatment cannot be carried out on the waste circulation pipeline in a self-adaptive manner and the like in the prior art, the rubber pad injection molding machine with the waste recycling function is provided. The application provides a rubber pad injection molding machine with a waste recycling function, which aim
