[0001] The utility model relates to the technical field of rubber processing, in particular to a rubber mixing machine. Background Art

[0002] Rubber mixing machine is mainly used for heat refining, sheeting, rubber breaking, plastic refining and mixing of rubber. Rubber mixing machine includes two rubber mixing rollers rotating in opposite directions. During use, the rubber is placed between the two rubber mixing rollers. The rubber is subjected to strong shearing action between the two rubber mixing rollers, thereby reducing the molecular weight and viscosity of the raw rubber molecules, thereby achieving the purpose of heat refining, plastic refining and mixing.

[0003] For example, the Chinese patent with publication number CN218052837U proposes a rubber mixing machine. The patent sets a second cutting device, adjusts the second cutting device according to the actual required film sliding width, fixes it with a first fastener, and cuts the film while the rubber mixing machine cuts the edge materials on both sides of the film. There is no need to cut the film into strips through other equipment, thereby improving the production efficiency of the film.

[0004] The above scheme still has the following disadvantages:

[0005] The movement of the cutter requires the staff to loosen the butterfly bolt and adjust the position of the mounting block to achieve the movement of the cutter. If the staff needs to cut the produced films to the same width, such manual adjustment method is likely to cause errors. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a rubber mixing machine, which solves the problem that errors are likely to occur in a manual adjustment method.

[0009] Preferably, the same-width cutting component also includes: a sliding groove, the sliding groove is opened on the inner bottom surface of the fixed frame, the interior of the sliding groove is connected to a limiting rod, the bottom surface of the moving block is connected to a sliding block, and the interior of the sliding block is slidably connected to the limiting rod.

[0010] Preferably, the same-width slitting component further comprises: a limiting frame, the limiting frame is connected to the inside of the fixed frame, a moving rod is connected to one side of the moving block, and the moving rod is slidably connected to the inside of the limiting frame.

When the rubber needs to be cut, the telescopic shaft of the electric push rod is extended or contracted to drive the moving block to move. When the moving block moves, it should be noted that the fixed block is stationary, so that the moving block can be linked by the short chain piece and the long chain piece, so that multiple moving blocks move synchronously, so that the moving block drives the blade to move synchronously, so that the spacing between each blade is the same, and the produced film can be cut into the same width through the blade, and when the moving block moves, The moving block will drive the sliding block to slide inside the sliding groove. When the sliding block slides, the limit rod can limit the sliding block, thereby improving the stability of the moving block when it moves. At the same time, when the moving block moves, the moving block will drive the moving rod to slide inside the limit frame, further improving the stability of the moving block when it moves. Compared with the prior art, the present application uses a synchronous movement method to make the spacing between multiple blades after movement the same, thereby achieving the effect of cutting the film with the same width, avoiding errors in manual adjustment. At the same time, when the moving block moves, the moving block is limited from two different directions by the sliding block at the bottom of the moving block and the moving rod on one side of the moving block, thereby improving the stability of the moving block when it moves.
