[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-7 A kneading machine for processing rubber accelerators includes a horizontally positioned base plate 1. The base plate 1 is made of metal commonly used in manufacturing kneading machines and is relatively heavy, forming a stable base. A vertically extending support plate 7 is fixedly connected to the top of the base plate 1. A fixed shell 2 with an opening on the right side is fixedly connected to the top of the support plate 7. Slide grooves 15 are fixedly connected to both the front and rear sides of the base plate 1. A slider 16 is slidably connected to the inner wall of the slide groove 15. The side of the slider 16 extends beyond the slide groove 15 and is fixedly connected to an inclined support frame 17. Support rods 18 are fixedly connected to the side of the support frame 17 facing the fixed shell 2. The two support rods 18 are fixedly connected by a split shell 3. The size of the split shell 3 is fixed, which limits the distance between the two support rods 18. This also prevents the slider 16 from detaching from the slide groove 15. The inclined setting of the support frame 17 is to allow the slider 16 to be on the left side of the slide groove 15, thus leaving space for the slider 16 to move to the right. When the slider 16 slides to the right in the slide groove 15, the split shell 3 will separate from the fixed shell 2.

[0024] Two motors 4 are mounted on the side of the fixed shell 2. A stirring rod 5 is fixedly connected to the output shaft of each motor 4. The end of the stirring rod 5 away from the motor 4 passes through the fixed shell 2 and extends into the interior of the split shell 3. Kneading blades 6 are fixedly connected to the surface of the stirring rod 5. Both motors 4 are drive motors commonly used in kneaders, and they work synchronously, driving the two stirring rods 5 to rotate in different directions. Figure 3 From a visual perspective, the two stirring rods 5 rotate in a concentrated manner towards their center. In general, from... Figure 3 Viewed from the plane of motor 4, the stirring rod 5 on the left rotates clockwise and the stirring rod 5 on the right rotates counterclockwise. The two motors 4 drive the two stirring rods 5 to rotate at different speeds. The purpose of this setting is to generate shearing force for the two side-by-side tangentially differentially arranged blades.

[0025] The side of the split shell 3 is integrally formed with a frame 8, which is movably inserted into the fixed shell 2. After insertion, the fixed shell 2 and the split shell 3 are aligned. The top of the split shell 3 is covered with a feeding cover 9, and the top of the feeding cover 9 is fixedly connected to a handle 24. The operator can lift the feeding cover 9 by using the handle 24 to expose the opening of the feeding cover 9 on the top of the split shell 3, so that materials can be fed into the split shell 3 and the fixed shell 2. An L-shaped discharge cover 10 is movably inserted into the split shell 3, and the discharge cover 10 is fixedly connected to a... Protrusion 11 is movably inserted into the insertion frame 8, and the discharge cover 10 is in contact with the insertion frame 8. During operation, the raw materials inside the fixed shell 2 and the split shell 3 are in a solid state, so there is no need for a separate sealing gasket to seal the connection gap between the discharge cover 10 and the split shell 3. This gap is extremely small; liquids and gases may pass through, but solids will not. A handle 12 is fixedly connected to the side of the discharge cover 10. The handle 12 facilitates the operation of the discharge cover 10. Two stabilizing plates 29 are fixedly connected to the handle 12. Each stabilizing plate 29 is fixedly connected to a stabilizing rod 30. The end of the stabilizing rod 30 away from the stabilizing plate 29 is movably inserted into the split shell 3. The initial insertion of the protrusion 11 forms a primary support structure, while the arrangement of the stabilizing plate 29 and the stabilizing rod 30 forms a secondary support structure, effectively preventing the discharge cover 10 from bending. A positioning plate 13 is fixedly connected to the side of the split shell 3, above the handle 12. A positioning pin 14 is movably inserted into the positioning plate 13. The positioning pin 14 consists of a top pin cap and a bottom pin rod, with the pin cap located at the top of the positioning plate 13. Furthermore, the bottom of the pin cap contacts the top of the positioning plate 13, while the pin rod extends downwards, passing through the positioning plate 13 and the handle 12, extending to the bottom of the handle 12. In this way, the handle 12 is locked by the positioning pin 14. When it is necessary to remove the discharge cover 10, pinch the pin cap and pull the positioning pin 14 upwards. The pin rod will then disengage from the handle 12. Then, pull the discharge cover 10 through the handle 12 to remove the discharge cover 10. This exposes the opening of the split shell 3 corresponding to the discharge cover 10, allowing for material discharge.

[0026] Two pads 19 are fixedly connected to the top of the base plate 1. Each pad 19 has a rotating groove in its top recess, and a ball bearing 25 is rotatably mounted in the rotating groove. The ball bearing 25 is in close contact with the bottom of the split shell 3. In this way, the pads 19 and the ball bearing 25 support the split shell 3, effectively preventing the split shell 3 from bending downwards. The ball bearing 25 can rotate flexibly in the rotating groove, so there is no large friction force, which will not affect the linear lateral movement of the split shell 3. One of the two pads 19 has a movement groove on one side. A track 20 is fixedly connected in the movement groove. A limit plate 21 is slidably connected to the surface of the track 20. The side of the limit plate 21 extends beyond the pad 19. The purpose of this setting is to facilitate the operation of the limit plate 21 by the operator. The side of the limit plate 21 is in contact with the inner wall of the movement groove. With the track 20 in place, the limiting plate 21 will only move linearly up and down within the movement slot, without rotating or disengaging from it. A limiting rod 22 is fixedly connected to the top of the limiting plate 21, and a limiting block 23 is fixedly connected to the side of the split shell 3 at the position corresponding to the limiting rod 22. The top of the limiting rod 22 passes through the limiting block 23, thus locking the relative position of the split shell 3 and the base plate 1, preventing the split shell 3 from sliding. To ensure that the limiting rod 22 can be stably inserted into the limiting block 23, a spring 31 is fitted on the surface of the track 20. The spring 31 needs to provide force when deformed, so the spring 31 supports the limiting plate 21, preventing it from moving downwards. When the limiting plate 21 is manually pressed downwards, the spring 31 is compressed, and the limiting plate 21 will cause the limiting rod 22 to disengage from the limiting block 23.

[0027] A sealing ring 27 is fixedly connected to the surface of the split shell 3. The sealing ring 27 is made of rubber. The inner wall of the sealing ring 27 is in close contact with the surface of the fixed shell 2. The left inner edge of the sealing ring 27 is chamfered. The purpose of this setting is to allow the fixed shell 2 to better open the sealing ring 27 when the split shell 3 moves towards the fixed shell 2, so that the sealing ring 27 can be well fitted onto the surface of the fixed shell 2.

[0028] A receiving box 28 with an open top is placed on the top of the base plate 1. The receiving box 28 is designed to catch the discharged material.

[0029] Finally, the production of rubber accelerators is a complete production line, and control equipment is generally required throughout the entire production line. In actual use, this technical solution also requires the use of a controller, which can be a conventional PLC controller, specifically the Siemens S7-1200. The control of mechanical equipment is an existing technology, and this technical solution does not include a controller because it is a conventional technology and does not require a controller. The kneader can also be used in conjunction with the control equipment in the entire production line.

[0030] In use, the feeding cover 9 can be removed by the handle 24, allowing raw materials to be fed into the fixed shell 2 and the split shell 3. Then, the controller controls the two motors 4 to work. The motors 4 will drive the kneading blades 6 to move through the stirring rod 5. The kneading blades 6 will process the raw materials. When discharging, pull the positioning pin 14 upwards and pull the discharge cover 10 by the handle 12 to discharge the material. When it is necessary to thoroughly clean the fixed shell 2 and the split shell 3, press the limiting plate 21 downwards. The spring 31 will shorten, and the limiting plate 21 will drive the limiting rod 22 to disengage from the limiting block 23. The operator pushes the split shell 3, which will cause the insert frame 8 to disengage from the fixed shell 2. The slider 16 will slide on the inner wall of the slide groove 15. The fixed shell 2 and the split shell 3 are separated, making it easy to expose the structure and clean.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
