[0002] In the production of rubber products, raw materials are typically mixed using a kneading mechanism to ensure material uniformity and performance stability. As a key piece of equipment in rubber processing, the pressure kneading mechanism's structural design and functional implementation directly impact production efficiency and product quality. Traditional kneading mechanisms often suffer from inconvenient maintenance and cleaning difficulties during long-term use, necessitating optimization and improvement to meet the demands of modern production.

[0003] In existing technologies, rubber kneading equipment mostly adopts a fixed roller structure. A motor drives a connecting shaft to rotate the kneading rollers, utilizing the shearing force and pressure between the rollers to complete the material mixing. This type of equipment typically uses direct bolt connections, requiring the disassembly of multiple fasteners for maintenance. Cleaning mainly relies on manual brushing or simple rinsing devices, making it difficult to achieve efficient and thorough cleaning of the equipment chamber.

[0004] However, the existing kneading roller fixing structure has significant drawbacks. When the kneading roller needs to be replaced or maintained, multiple fixing bolts must be completely removed, which is a cumbersome and time-consuming process. Furthermore, repeated disassembly and reassembly can easily lead to loosening of the connections, affecting the stability of equipment operation. This structure not only increases the difficulty of maintenance but may also shorten the service life of the equipment, seriously impacting production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pressure kneading mechanism for rubber products, which aims to improve the problem that when existing products need to replace or maintain the kneading rollers, multiple fixing bolts must be completely disassembled, which is a cumbersome and time-consuming operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure kneading mechanism for rubber products, comprising a base plate, a fixing plate fixedly connected to the outer wall of the base plate, a support leg fixedly connected to the upper surface of the base plate, a kneading box fixedly connected to the upper surface of the support leg, a kneading roller rotatably connected to the inner wall of the kneading box, a motor fixedly connected to the upper surface of the fixing plate, a connecting shaft fixedly connected to the output end of the motor, and a quick-release assembly provided on the inner wall of the kneading roller;

Detailed Implementation

[0025] 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.

[0026] Reference Figure 1 - Figure 4 An embodiment of this utility model is provided: a pressure kneading mechanism for rubber products, including a base plate 1, a fixing plate 2 fixedly connected to the outer wall of the base plate 1 for fixing the installation position of the motor 5, a support leg 4 fixedly connected to the upper surface of the base plate 1, a kneading box 3 fixedly connected to the upper surface of the support leg 4, the main working cavity for accommodating rubber materials for kneading processing, a kneading roller 7 rotatably connected to the inner wall of the kneading box 3, the core component for directly kneading rubber materials, a motor 5 fixedly connected to the upper surface of the fixing plate 2 to provide power to drive the connecting shaft 6 to rotate, a connecting shaft 6 fixedly connected to the output end of the motor 5 to transmit the power of the motor 5 to the kneading roller 7, and a quick-release assembly provided on the inner wall of the kneading roller 7;

[0027] The quick-release assembly includes a locking block 9, which enables quick assembly and disassembly of the kneading roller 7 by engaging with the connecting shaft 6. The outer wall of the locking block 9 is slidably connected to the inner wall of the kneading roller 7. A fixed shaft 10 is rotatably connected inside the locking block 9. A spring 11 is fixedly connected to the outer wall of the locking block 9 to provide elasticity and keep the locking block 9 in the locked state. A fixing plate 8 is fixedly connected to one end of the spring 11 to fix the spring 11 and limit the range of motion of the locking block 9. A bolt 12 is threaded inside the kneading roller 7 to control the engagement and disengagement of the locking block 9 through the threaded connection.

[0028] Specifically, motor 5 drives kneading roller 7 to rotate via connecting shaft 6 to mix rubber materials. When it is necessary to disassemble kneading roller 7, first loosen bolt 12 to disengage it from the inner wall of kneading roller 7. At this time, the locking block 9 moves outward along fixed shaft 10 under the elastic force of spring 11, disengaging from the locking state with connecting shaft 6, thereby releasing the fixed connection between kneading roller 7 and connecting shaft 6. Then, kneading roller 7 is slid out along the outer wall of connecting shaft 6 to complete the disassembly operation. Fixed plate 8 maintains the limiting effect of locking block 9 through spring 11 to ensure that kneading roller 7 maintains a stable connection with connecting shaft 6 during normal operation and avoids loosening during operation.

[0029] Reference Figure 1 and Figure 5 A lid 13 is provided on the upper surface of the kneading box 3. A feed pipe 14 is fixedly connected to the inner wall of the lid 13 for adding rubber material into the kneading box 3. A cleaning assembly is provided above the lid 13. The cleaning assembly includes a nozzle 20, which sprays cleaning liquid evenly onto the inner wall of the kneading box 3. The nozzle 20 is located above the lid 13. One end of the nozzle 20 is fixedly connected to a connecting pipe 19, which delivers the cleaning liquid from the water pump 18 to the nozzle 20. A water tank 16 is fixedly connected to the outer wall of the kneading box 3 for storing cleaning water. A water pump 18 is fixedly connected to the upper surface of the water tank 16 to provide pressure to deliver the cleaning liquid to the nozzle 20. A connecting pipe 17 is fixedly connected to the input end of the water pump 18 to deliver water from the water tank 16 to the water pump 18. The output end of the water pump 18 is connected to the connecting pipe 19. One end of the second pipe 19 is fixedly connected. A hinge 21 is provided on the outside of the box cover 13 to realize the opening and closing function of the box cover 13. A handle 22 is fixedly connected to the outer wall of the box cover 13. A support frame 15 is fixedly connected to the upper surface of the box cover 13. The second pipe 19 is supported and fixed. The inner wall of the connecting shaft 6 is slidably connected to the outer wall of the kneading roller 7. The lower surface of the second fixed plate 8 is fixedly connected to the outer wall of the connecting shaft 6. The outer wall of the bolt 12 is rotatably connected to the inside of the locking block 9. The motor 5 is set on one side of the outer wall of the kneading box 3. The kneading box 3 is set above the bottom plate 1. The second pipe 19 is attached to the outer wall of the support frame 15. The water pump 18 is set on one side of the outer wall of the kneading box 3. The water tank 16 is set above the bottom plate 1. The second pipe 19 is set above the box cover 13. The motor 5 is fixedly connected to the outer wall of the bottom plate 1.

[0030] Specifically, the water pump 18 is started to draw the cleaning solution in the water tank 16 through the connecting pipe 17 and then through the connecting pipe 29 to the nozzle 20. The nozzle 20 sprays the cleaning solution evenly on the inner wall surface of the kneading box 3, effectively dissolving and rinsing the residual rubber material. The box cover 13 is opened and closed by the hinge 21, which makes it easy to observe the internal cleaning status. The handle 22 provides a convenient opening and closing point for the operator. The support frame 15 provides a fixed support for the connecting pipe 29, ensuring that the nozzle 20 maintains a stable spray angle. After cleaning, the waste liquid is discharged through the outlet set at the bottom of the kneading box 3, completing the entire cleaning and maintenance process.

[0031] Working principle: When the pressure kneading mechanism for rubber products is needed, when the kneading roller 7 needs to be disassembled, first loosen the bolt 12 so that it is disconnected from the inner wall of the kneading roller 7. At this time, the locking block 9 moves outward under the elastic force of the spring 11, disengaging from the locking state with the connecting shaft 6, thereby releasing the fixation between the kneading roller 7 and the connecting shaft 6. Then, the kneading roller 7 is slid out along the outer wall of the connecting shaft 6 to complete the disassembly. The fixing plate 8 is kept in place by the spring 11 to limit the locking block 9, ensuring that the kneading roller 7 is stably connected during normal operation.

[0032] In addition, when it is necessary to clean the inner wall of the kneading box 3, the water pump 18 is started to draw water from the water tank 16 through the connecting pipe 17 and then through the connecting pipe 29 to the nozzle 20. The nozzle 20 sprays the cleaning liquid evenly on the inner wall of the kneading box 3 to dissolve the residual rubber material. The box cover 13 is designed to be opened and closed by the hinge 21, which makes it easy to observe the cleaning effect. At the same time, the handle 22 makes it easy for the operator to open and close the box cover 13. The support frame 15 supports the connecting pipe 29. The waste liquid after cleaning can be discharged through the bottom of the kneading box 3 to complete the cleaning and maintenance of the inner wall of the box.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
