Description

Technical Field

[0001] The utility model belongs to the technical field of rubber processing, and particularly relates to a rubber strip mixing device. Background Technique

[0002] Rubber processing is the process of making rubber into rubber products. The basic processes of various rubber product processing include basic processes such as plasticating, mixing, calendering or extruding (i.e., extrusion), forming, and vulcanization. Each process has different requirements for the product and is respectively combined with several auxiliary operations.

[0003] When performing rubber mixing operations, a mixer is used. The traditional mixer only has two mixing drums. The raw materials are placed between a pair of mixing drums for extrusion heating. The heating is achieved through the inside of the mixing drums. The function of heating is to appropriately melt the rubber sheet, facilitate uniform mixing during extrusion, and discharge the internal air bubbles during extrusion. Since relatively strong force is applied during extrusion, manual pulling is also required for discharging, and the worker needs to stand in front of the mixer for a long time;

[0004] The distance between the two mixing drums of the mixer is relatively fixed. When processing thicker rubber strips, the distance between the two mixing drums needs to be adjusted multiple times, which is rather cumbersome. Moreover, during the feeding process of rubber strip mixing, manual handling of the rubber strip is required, with a large labor intensity, which is not conducive to the efficient processing of rubber strips by workers. Based on this, the utility model provides a rubber strip mixing device. Content of the Utility Model

[0026] The working principle and use process of the utility model are as follows: the staff starts the No. 2 electric hydraulic push rod 21 to adjust the use height of the loading plate 22. When the loading plate 22 contacts the ground (or a suitable height), the staff puts the rubber strip on the loading plate 22. Then the staff restarts the No. 2 electric hydraulic push rod 21 to move the loading plate 22 to the initial height (the height of the loading plate 22 and the auxiliary discharge plate 19 relative to each other). Then the staff pushes the rubber strip to move one end of the rubber strip to the No. 1 pressure roller 9. Then the staff starts the No. 1 electric hydraulic push rod 14. The No. 1 electric hydraulic push rod 14 drives the No. 2 bearing seat 15 to move downward, and the No. 2 pressure roller 16 moves downward synchronously with the No. 2 bearing seat 15. When the No. 2 pressure roller 16 contacts the rubber strip and squeezes the rubber strip, the staff starts the motor 10.
