Description

Technical Field

[0001] The invention relates to a rubber and plastic open mixing mill, in particular to an automatic rubber and plastic open mixing mill with a material guiding manipulator, belonging to the technical field of rubber and plastic machinery. Background Art

[0002] In the field of rubber and plastic processing technology, there are many categories that need to be melted and blended by internal mixers and open mixers. Generally, products such as natural rubber, synthetic rubber, ethylene-vinyl acetate copolymer, etc., which are vulcanized and molded by vulcanizers and injection molded by new processes, must be dispersed and mixed by internal mixers and open mixers. After the raw material formula according to specific technical requirements is mixed by internal mixers, the raw materials and compound materials that were originally colloids, particles, and powders are fused and melted into agglomerates. However, the degree of dispersion between the various compound materials and the rubber (plastic) in the raw materials is still very low, and only a certain degree of dispersion is achieved. In order to fully disperse the various components in the agglomerate and become flakes or granules that can enter the next process, according to industry terminology, it must also go through the thinning, triangle packing, sheeting or granulation of the open mixer. These procedures are traditionally completed manually on the open mixer.

[0003] The so-called thin pass and triangle package is to roll the rubber mass into thinner sheets by the roller of the open mixing mill, and then cut the film wrapped on the surface of the roller along the axis on the roller. The film is continuously rolled out by the roller, and the films at the left and right corners are manually stacked to the middle inside to form a triangle with the sharp corners facing outward, and then the sharp corners of the triangle are stacked inward to form an outer straight edge, and the previous stacking action is repeated until all the rubber masses on the machine are beaten into a large triangle package. The purpose of this is to mix and overlap the rubber materials in various directions through repeated triangle stacking, and then directly "sheet" the triangle package after the next process of thin pass, so that it becomes a fully dispersed rubber material to be vulcanized. Its essence is equivalent to stirring and dispersing in the field of injection molding technology.

[0004] The disadvantages of this rubber mixing process are: first, the work efficiency is extremely low, because each process conversion in the complete process on the rubber mixing machine requires the roller spacing adjustment, and adjusting the roller spacing will cause the rubber mixing machine to operate inefficiently for a long time; secondly, whether it is loading and unloading rubber or making triangle bags, it all depends on manual operation, which is not only labor-intensive, but the degree of implementation of the technical standards of the operation process depends entirely on the on-site control of the operator, and it cannot be strictly implemented according to the standards, and the quality of the product cannot be unified and stable. Summary of the invention

[0005] In order to solve the technical defects in the above-mentioned rubber mixing process, the present invention provides an automatic rubber and plastic mixing mill with a material guiding manipulator.

[0006] The technical scheme adopted by the present invention is: an automatic rubber and plastic open mill with a material guiding manipulator, which is composed of an open mill body, a feeder, a roller gap adjuster and a material guiding manipulator. The open mill body includes a base frame, left and right side frames and rollers. The lower sides of the left and right side frames are connected to the left and right sides of the upper side of the base frame as an integrated structure. The rollers are composed of a front roller and a rear roller, and the shafts at both ends are installed on the upper end between the left and right side frames; the feeder is a belt conveyor structure and is installed on the base frame between the left and right side frames; the roller gap adjuster is a structure in which the rollers are driven to move by a CNC signal command drive assembly, and the roller gap adjuster is composed of two synchronized components and are respectively installed on the upper ends of the left and right side frames in front of them; the material guiding manipulator includes a fixed plate, a movable guide rod, a movable plate, a movable oil and gas cylinder, a manipulator body and a controller, and the fixed plate is composed of two strip plates and are respectively fixed longitudinally between the roller in front of the front roller and the feeder On the inner sides of the left and right side frames, the movable guide rods are composed of two and both ends are connected to the front and rear ends between the two fixed plates. The movable plate is a rectangular plate and the upper front end is installed between the two movable guide rods through at least four guide rod sliders. The movable oil and gas cylinder is a power source for driving the movable plate to move left and right and the cylinder body is installed in front of the left frame or the right frame. The telescopic end of the movable oil and gas cylinder is connected to the front end of the movable plate through a first connecting plate. The manipulator body is composed of two sets and includes a telescopic guide rod, a telescopic oil and gas cylinder and a material guide arm. The telescopic guide rod is installed on the left and right sides below the rear end of the movable plate through a sliding sleeve. The telescopic oil and gas cylinder is installed on the side of the telescopic guide rod and the telescopic end is connected to the telescopic guide rod through a second connecting plate. The material guide arm is connected to the rear end of the telescopic guide rod. The controller is a control center that automatically moves left and right and telescopes forward and backward according to the set program and frequency by the intelligent control program.

[0007] The beneficial effects of the present invention are as follows: after the operating parameters are input into the controller after the mixing mill is started, when the rubber material is rolled into sheets distributed left and right between the front and rear rollers and transmitted to the feeder below, the mobile oil and gas cylinder installed on one side of the side frame pushes and pulls the moving plate left and right according to the set telescopic frequency. When the moving plate starts to move right, the left manipulator extends to push the film to the right for collection and stacking. When the moving plate starts to move left, the right manipulator extends to pull the film to the left for collection and stacking, while the left manipulator retracts. Because the film is continuously transmitted downward between the front and rear rollers and continuously collected and stacked left and right by the manipulator, the film is extended left and right and is collected and stacked into multiple stacks that overlap left and right and cover front and back. In this way, the roller spacing adjuster and the material guiding manipulator completely replace the manual operation of roller spacing adjustment and "triangle bagging", realizing a completely intelligent and automated fast, accurate and efficient operation, reducing labor intensity, reducing labor costs and improving

[0008] Production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
