Door gasket processing and production assembly line

Abstract

The invention discloses a door gasket processing and production assembly line which comprises an extrusion molding mechanism, a metering transmission mechanism, a cutting device, an automatic magneticstrip penetrating and distributing production line, a full-automatic welding production line and a control device in sequential connection. The defect that an extruding amount of a screw extruder inthe prior art is unstable is overcome, and adverse effects on molding of door gaskets are reduced to the maximum extent; the defect that molding sizes of door gaskets fluctuate due to the difference of transmission speeds of an upper synchronous belt and a lower synchronous belt of a metering transmission mechanism in the prior art is also overcome, and the extrusion deformation of the door gaskets and the fluctuation of the molding sizes of the door gaskets are avoided; the defect that production efficiency of the door gaskets drops due to collecting and stacking of the cut-off door gaskets and use of steering engines in the prior art is overcome, and production efficiency of the door gaskets is improved; and through several automatic processes of automatic mold entering, positioning, transferring, welding, piece picking and the like, the full-automatic production of the door gaskets of refrigerators from semi-finished products to finished products is realized.

Description

technical field [0001] The invention relates to a production line for processing door seals. Background technique [0002] The refrigerator door seal is a kind of refrigerator accessory used to seal between the refrigerator door and the cabinet. However, there are some technical problems in the production and processing of existing door seals: [0003] First, the molding problem. For the door seal extrusion molding production line currently used by domestic enterprises, the forming problem of the door seal is mainly caused by the fluctuation of the extrusion volume of the screw extruder. The main reason for the instability of the extrusion volume of the screw extruder itself is that the material cannot enter the screw barrel evenly; the wear and tear of the gap between the screw barrel and the screw becomes larger, resulting in fluctuations caused by the reverse flow of the material when it is conveyed inside the barrel; the connection at the outlet of the barrel The filt...

Problems solved by technology

[0010] The purpose of the present invention is to provide a door seal processing production line, which overcomes the problem of unstable extrusion volume of the screw extruder existing in the prior art, and minimizes the adverse effects on the door seal forming; It also overcomes the problem in the prior art that there is a gap between the transmission speeds of the upper synchronous belt and the lower synchronous belt of the metering transmission mechanism, which leads to fluctuations in the forming size of the door seal, avoiding extrusion deformation of the door seal and fluctuations in the forming size of the door seal; It solves the problems in the prior art that the production efficiency of door seals is reduced due to the collection and stacking of cut door seals and the use of steering machines, and improves the production efficiency of door seals; at the same time, through automatic mold entry, automatic positioning, automatic transfer, Some automatic processes such as automatic welding and automatic pick-up realize the fully automatic production of refrigerator door seals from semi-finished products to finished products
