Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing machines, and specifically, to a reciprocating discharging mechanism of a rubber product mixing machine. Background Art

[0002] Rubber is a polymer material. The rubber mixing process refers to making rubber raw materials into rubber compounds that can be used to manufacture various rubber products through chemical reactions and physical treatments. An open rubber mixing machine is a commonly used rubber mixing device. When processing rubber (such as silicone rubber, silica gel, etc.) products, workers put the rubber that has been extruded once back between two rubber mixing rollers for re-mixing. Since the rubber has a large volume, when workers turn it over, they need to pick up the rubber pressed into sheets by hand for winding. The operation is not only difficult but also greatly increases the labor intensity. Secondly, when picking up and turning the rubber, a pair of rubber mixing rollers are always rotating, posing a safety hazard to the workers.

[0003] In addition, soft rubber has a certain adhesiveness and is prone to adhering to the rubber mixing rollers after rolling. Although most of the rubber sheets can be lifted during the process of picking up and turning, there will still be residues, which need to be manually cleaned at intervals, and it is also quite troublesome.

When cleaning the surface of the rubber mixing roller 2, turn the adjusting screw 4-2 to stick the scraping shovel 4-5 to the surface of the rubber mixing roller 2, and clean the rubber into the collection box. Then start the driving motor 5-4, and the driving gear 5-5 drives the outer gear 5-3 to rotate the receiving box 5-6 to the top, and the rubber returns between the rubber mixing rollers 2 to continue rubber mixing. Finally, after completion, start the second motor 6-3 to control the upward rotation of the material receiving hopper 6-2, then start the telescopic cylinder 6-6, and press the material receiving hopper 6-2 through the fixing block 6-7, and push the rubber into the material receiving hopper 6-2. Then turn the material receiving hopper 6-2 downward and take away the rubber.

[0054] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model.
