Description

Technical Field

[0001] This utility model relates to the field of kneading machine technology, specifically to a stirring shaft structure for a silicone rubber kneading machine. Background Technology

[0002] Kneaders are ideal equipment for kneading, mixing, vulcanizing, and polymerizing high-viscosity, elasto-plastic materials. Kneaders can be used to produce silicone rubber, sealants, hot melt adhesives, food adhesives, pharmaceutical preparations, etc. A kneader is a special mixing and stirring device. The most common type uses two blades arranged in a parallel tangential differential speed configuration, where one blade moves at a high speed and the other at a low speed to generate shear force. The different blade speeds allow the materials to be mixed quickly and evenly. Vacuum kneaders are a type of kneader, mainly used in the chemical production of silicone rubber, glass glue, butyl rubber, hot melt adhesives, etc. Kneaders typically consist of several major components, including a kneading system, a vacuum system, a heating system, a cooling system, and an electrical control system.

[0003] In existing technology, two paddles are driven to rotate inside the box by a transmission gear set, which enables the materials to be mixed together quickly, thus improving the mixing speed and effect.

[0004] However, in actual use, due to the high viscosity of the mixed materials, when the servo motor drives the paddle to rotate through the gear set, the gear set itself will be subjected to great pressure, which will increase the wear of the gear set and require frequent replacement by the staff, thus affecting work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stirring shaft structure for a silicone rubber compound kneader. This solves the problem that in actual use, due to the high viscosity of the mixed materials, when the servo motor drives the paddles to rotate through the gear set, the gear set itself is subjected to great pressure, resulting in increased wear on the gear set, requiring frequent replacement by operators, and affecting work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stirring shaft structure for a silicone rubber compound kneader, comprising a housing, a kneading shaft rotatably connected to the inner wall of the housing via a sealed bearing, a connecting rod fixedly connected to one end of the kneading shaft extending to the outside of the housing, a sleeve fitted onto the outer wall of the connecting rod, a transmission gear fixedly connected to the outer wall of the sleeve, a drive gear meshing with the outer wall of the transmission gear, a fixed shell provided on the outer wall of the drive gear, an installation shell inserted into the inner wall of the fixed shell, the outer wall of the installation shell fixedly connected to the outer wall of the housing, and a limit device installed on the outer wall of the transmission gear.

[0007] Preferably, the limiting device includes a strip block, the outer wall of which is slidably engaged with the inner wall of the sleeve, and the two outer walls of the transmission gear are respectively pressed against the support shells, and the outer walls of the two support shells are respectively fixedly connected to the inner wall of the fixed shell and the outer wall of the box.

[0008] Preferably, a plug is fixedly connected to the end of the connecting rod away from the housing, a connecting block is sleeved on the outer wall of the plug, a support rod is fixedly connected to the outer wall of the connecting block, and the outer wall of the support rod is rotatably connected to the inner wall of the fixed housing through a sealed bearing.

[0009] Preferably, the mounting shell and the fixed shell are respectively fixedly connected to the side of each other, and the inner wall of the two fixed blocks is inserted with a threaded rod. The side of the threaded rod near the mounting shell is rotatably connected to the top of the mounting shell by a pin. The other side of the threaded rod is threadedly connected to a top block, and the outer wall of the top block abuts against the outer wall of the fixed block.

[0010] Preferably, a servo motor is fixedly connected to the outer wall of the fixed housing. A drive rod is fixedly connected to one end of the servo motor through a sealed bearing. A rhombus-shaped block is fixedly connected to the end of the drive rod away from the servo motor. The outer wall of the rhombus-shaped block is inserted into the outer wall of the drive gear. The outer wall of the drive gear is rotatably connected to the outer wall of the housing through a sealed bearing. Beneficial effects

[0011] This utility model provides a stirring shaft structure for a silicone rubber compound kneader. It offers the following advantages: The stirring shaft structure of this silicone rubber compound kneader, through the cooperation of a sleeve, a transmission gear, and a connecting rod, allows for easy replacement of the transmission gear. When the transmission gear needs to be replaced, the sleeve is pulled off the connecting rod, enabling gear replacement. Conversely, during installation, the transmission gear is fitted onto the outer wall of the drive rod. This facilitates gear replacement and makes it convenient for operators. It also solves the problem of highly viscous mixed materials, where the gear set itself experiences significant pressure when the servo motor drives the paddles via the gear set, leading to excessive wear and frequent gear replacement, thus reducing work efficiency.

[0012] By using the mounting shell, the fixed shell, and the threaded rod, when replacing the transmission gear, the handle is used to rotate the top block, which separates the top block from the fixed block. This allows the threaded rod to drive the top block to rotate around the position where the threaded rod and the fixed shell rotate, thus allowing the mounting shell to be removed from the fixed shell. This solves the problem of inconvenience for workers when disassembling the device to replace the transmission gear. Attached Figure Description

[0018] 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.

[0019] In actual use, due to the high viscosity of the mixed materials, when the servo motor drives the paddle to rotate through the gear set, the gear set itself will be subjected to great pressure, which will increase the wear of the gear set and require frequent replacement by the staff, thus affecting work efficiency.

[0020] In view of this, the present invention provides a stirring shaft structure for a silicone rubber kneading machine, which solves the problem that in actual use, due to the high viscosity of the mixed material, when the servo motor drives the paddle to rotate through the gear set, the gear set itself will be subjected to great pressure, resulting in increased wear of the gear set, requiring frequent replacement by the operator, and affecting work efficiency.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0022] Example 1: By Figure 1-4It is known that a stirring shaft structure of a silicone rubber compound kneader includes a housing 1. The inner wall of the housing 1 is rotatably connected to a kneading shaft 2 via a sealed bearing. A connecting rod 9 is fixedly connected to one end of the kneading shaft 2 extending to the outside of the housing 1. A sleeve 14 is sleeved on the outer wall of the connecting rod 9. A transmission gear 8 is fixedly connected to the outer wall of the sleeve 14. A drive gear 7 is meshed with the outer wall of the transmission gear 8. A fixed shell 4 is provided on the outer wall of the drive gear 7. An installation shell 3 is inserted into the inner wall of the fixed shell 4. The outer wall of the installation shell 3 is fixedly connected to the outer wall of the housing 1. A limit device is installed on the outer wall of the transmission gear 8.

[0023] In the specific implementation process, it is worth noting that the size of the inner wall of the sleeve 14 is the same as the size of the connecting rod 9. When installing the transmission gear 8, the sleeve 14 is placed on the outer wall of the connecting rod 9. When replacing the transmission gear 8, the sleeve 14 on the inner wall of the transmission gear 8 is placed on the outer wall of the connecting rod 9. This makes it convenient to replace the damaged transmission gear 8. This allows the connecting rod 9 to drive the meshing shaft 2 to rotate synchronously when the drive gear 7 drives the transmission gear 8 to rotate. The meshing shaft 2 and the housing 1 are technologies known to those skilled in the art, so they will not be described in detail.

[0024] Furthermore, the limiting device includes a strip block 15, the outer wall of the strip block 15 is slidably engaged with the inner wall of the sleeve 14, and the two outer walls of the transmission gear 8 are respectively pressed against the support shell 10. The outer walls of the two support shells 10 are respectively fixedly connected to the inner wall of the fixed shell 4 and the outer wall of the box 1.

[0025] In the specific implementation process, it is worth noting that a groove is provided on the inner wall of the sleeve 14 to fit the strip block 15. When the connecting rod 9 is installed, it will make the connection between the connecting rod 9 and the transmission gear 8 more stable. In addition, a ball bearing is provided at the contact position between the support shell 10 and the transmission gear 8, which can reduce the friction between the support shell 10 and the transmission gear 8, thereby making the transmission gear 8 stable when rotating.

[0026] Furthermore, a plug block 16 is fixedly connected to the end of the connecting rod 9 away from the housing 1. A connecting block 17 is sleeved on the outer wall of the plug block 16. A support rod 18 is fixedly connected to the outer wall of the connecting block 17. The outer wall of the support rod 18 is rotatably connected to the inner wall of the fixed shell 4 through a sealed bearing.

[0027] In the specific implementation process, it is worth noting that the shape of the insert 16 is rectangular, and the groove on the outer wall of the connecting block 17 is the same. In this way, after the insert 16 is inserted into the connecting block 17, when the transmission gear 8 drives the connecting rod 9 to rotate, the support rod 18 rotates synchronously. Thus, with the support of the support rod 18, the transmission gear 8 is stable when rotating.

[0028] Example 2: From Figure 1-4It can be seen that the mounting shell 3 and the fixed shell 4 are respectively fixedly connected to the side of the two fixed blocks 19 that are close to each other. The inner walls of the two fixed blocks 19 are inserted with threaded rods 12. The side of the threaded rod 12 that is close to the mounting shell 3 is rotatably connected to the top of the mounting shell 3 through a pin. The other side of the threaded rod 12 is threadedly connected to a top block 13. The outer wall of the top block 13 is pressed against the outer wall of the fixed block 19.

[0029] In the specific implementation process, it is worth noting that one end of the threaded rod 12 is connected to the outer wall of the fixed shell 4 by a pin. The top of the two fixed blocks 19 is provided with a groove into which the threaded rod 12 can be inserted. When the mounting shell 3 is installed on the fixed shell 4, the two fixed blocks 19 will be aligned. At the same time, the threaded rod 12 will be rotated 90 degrees so that the threaded rod 12 is inserted into the inner wall of the two fixed blocks 19. The top block 13 on the outer wall of the threaded rod 12 will be rotated by the handle. Through the threaded connection between the top block 13 and the threaded rod 12, the top block 13 will be pressed against the outer wall of the fixed block 19. In this way, the mounting shell 3 is fixed to the outer wall of the fixed shell 4, which makes it convenient for workers to install it.

[0030] Furthermore, a servo motor 5 is fixedly connected to the outer wall of the fixed housing 4. A drive rod 6 is fixedly connected to one end of the servo motor 5 through a sealed bearing. A rhombus block 11 is fixedly connected to the end of the drive rod 6 away from the servo motor 5. The outer wall of the rhombus block 11 is inserted into the outer wall of the drive gear 7. The outer wall of the drive gear 7 is rotatably connected to the outer wall of the housing 1 through a sealed bearing.

[0031] In the specific implementation process, it is worth noting that a slot is provided on the outer wall of the drive gear 7 to fit the rhombus block 11. When the housing 3 is disassembled and installed, the rhombus block 11 will be moved out of the outer wall of the drive gear 7, so as not to be affected when replacing the transmission gear 8. Under the drive of the servo motor 5, the drive gear 7 drives the transmission gear 8 to rotate, so that the kneading shaft in the housing 1 rotates synchronously. The model of the servo motor 5 is not limited, as long as it meets the actual use.

[0032] 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.
