Description

Technical Field

[0001] This application relates to the field of rubber belt reorientation technology, and in particular to a rubber belt reorientation device for vulcanizing flexible rubber roller sleeves. Background Technology

[0002] Vulcanization is a key process in rubber processing. It transforms rubber from a plastic to an elastic state through a chemical reaction, thereby endowing rubber products with the desired physical and chemical properties. In equipment such as printers, flexible rubber rollers are crucial components, and their quality directly affects printing quality and the equipment's lifespan. Therefore, ensuring that the rubber belt maintains a stable position and orientation during vulcanization is extremely important in the production process.

[0003] Currently, the vulcanization process of rubber belts typically involves multiple steps, such as infrared heating, microwave heating, and hot air circulation. To transport the rubber belts from one processing stage to the next, equipment such as conveyor belts is usually used.

[0004] However, when the rubber belt is transferred from one frame to another, it is prone to shifting due to factors such as equipment precision, improper operation, or the characteristics of the rubber belt itself, which can affect the production quality of the rubber. Utility Model Content

[0005] The purpose of this application is to address the problem that rubber belts are prone to misalignment when being transferred from one frame to another due to factors such as equipment precision, improper operation, or the inherent characteristics of the rubber belts themselves, thereby affecting the production quality of rubber. This application provides a rubber belt reversing device for vulcanizing flexible rubber roller sleeves.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A rubber belt redirection device for vulcanizing flexible rubber roller sleeves includes a mounting base. One end of the mounting base has a tensioning groove, and a tensioning slider is slidably connected inside the tensioning groove. One end of the tensioning slider is rotatably connected to a tensioning wheel. One end of the mounting base is symmetrically rotatably connected to a positioning wheel, and the tensioning wheel is installed between two positioning wheels. A rubber raw material belt is wound around one end of the tensioning wheel and the positioning wheel. One end of the mounting base is symmetrically provided with a diagonal frame, and one end of the diagonal frame is rotatably connected to a redirection roller. The output end of the rubber raw material belt passes between the two redirection rollers. A tensioning assembly is installed at one end of the mounting base.

[0008] By adopting the above technical solution, and by setting up the coordinated use of the tensioning wheel, positioning wheel, redirecting roller, and tensioning assembly, it is convenient for the traction rubber raw material belt to move from one processing step to the next, bypassing the bottom of the tensioning wheel and the top of the positioning wheel, and passing between the two redirecting rollers. With the help of gravity, it moves centrally along the guiding direction of the two redirecting rollers. At the same time, the tensioning assembly pushes the tensioning wheel to form contact with the middle section of the rubber raw material belt to maintain the tension of the rubber raw material belt, reducing the possibility of the rubber raw material belt loosening and shifting. This effectively improves the stability of the movement of the rubber raw material belt between two processes and improves the production quality of the rubber raw material belt.

[0009] Furthermore, the tensioning assembly includes tensioning slide rods symmetrically and fixedly connected to one end of the mounting base. One end of the tensioning slide rod passes through the tensioning groove and is fixedly connected to a tensioning slide plate. One end of the tensioning slide plate is slidably connected to the tensioning slide rod. One end of the tensioning slide rod is fitted with a tensioning spring, and the tensioning spring is installed between the tensioning slide plate and the mounting base.

[0010] By adopting the above technical solution and using the tension spring and tensioning slide in combination, the elastic deformation characteristics of the tension spring can be utilized. When the rubber material belt loosens and causes the tensioning wheel to change the force applied to the tension spring, the tension spring will rebound and push the tensioning wheel to make contact with the rubber material belt, thereby maintaining the tension of the rubber material belt. This reduces the possibility of deviation caused by the loosening of the rubber material belt and further improves the stability of the device.

[0011] Furthermore, one end of the mounting base is provided with a pair of adjusting slide grooves, and an adjusting rod is rotatably connected inside the two adjusting slide grooves. One end of the adjusting rod is provided with a threaded groove with opposite rotation direction. One end of the adjusting rod passes through the mounting base and is fixedly connected to an adjusting handle. One end of the inclined bracket is slidably connected inside the adjusting slide groove and is threadedly connected to the adjusting rod.

[0012] By adopting the above technical solution, and by setting the adjustment rod and the adjustment slide groove to work together, it is easy to rotate the adjustment handle to drive the adjustment rod to form a threaded connection with the inclined frame, and drive the two inclined frames to drive the two redirecting rollers to move away from or towards each other along the length of the adjustment slide groove, thereby improving the applicability of the device.

[0013] Furthermore, one end of each of the two tensioning slide rods is slidably fitted with an abutting slide plate, which abuts against one end of the tensioning spring. The top of the abutting slide plate is rotatably connected to an abutting screw. One end of the mounting base is rotatably connected to a driving sleeve rod, which is threadedly connected to one end of the abutting screw rod. One end of the mounting base is equipped with an adjustment mechanism.

[0014] By adopting the above technical solution, and by setting up the adjustment mechanism in conjunction with the contact screw and the drive sleeve, it is convenient to drive the drive sleeve to rotate when the adjustment mechanism is started, thereby driving the drive sleeve to connect with the contact screw. This causes the contact screw to drive the contact plate to contact the tension spring, and pushes the tension spring to move towards the tension plate, thereby changing the spring's rebound stroke. This allows for the adjustment of the tension strength of the tension wheel to adapt to rubber material belts of different thicknesses, further improving the applicability of the device.

[0015] Furthermore, the adjustment mechanism includes a bevel gear one fixedly connected to one end of the drive sleeve rod, a bevel gear two meshing with the bevel gear one rotatably connected to one end of the mounting base, an adjustment motor fixedly connected to one end of the mounting base, the output end of the adjustment motor fixedly connected to the bevel gear two, and a guide component installed at one end of the mounting base.

[0016] By adopting the above technical solution, and by setting the guide component to cooperate with bevel gear one and bevel gear two, it is convenient to start the adjustment motor to drive bevel gear two to mesh with bevel gear one, and make bevel gear one drive the drive sleeve rod to rotate. At the same time, the drive sleeve rod is threadedly connected to the contact screw rod, and pushes the contact screw rod to move along the length direction of the tensioning slide rod, which effectively improves the practicality of the device.

[0017] Furthermore, the guiding component includes a guiding groove formed at one end of the mounting base, and a guiding slider is slidably connected inside the guiding groove. The guiding slider is rotatably connected to the abutting screw.

[0018] By adopting the above technical solution, and by setting up the guide slider and guide groove in combination, it is convenient to guide the movement direction of the contact screw, thereby improving the stability of the device.

[0019] Furthermore, a limit plate is fixedly connected to the outer side of both the positioning wheel and the tensioning wheel.

[0020] By adopting the above technical solution, and by setting the limit plate in conjunction with the tensioning wheel and the positioning wheel, it is convenient to guide and limit the rubber raw material belt that passes around the end of the tensioning wheel and the positioning wheel, which effectively improves the practicality of the device.

[0021] Furthermore, the surfaces of the tensioning wheel, positioning wheel, and redirecting roller are all coated with a silane coating.

[0022] By adopting the above technical solution, the wear resistance and anti-stick properties of the tensioning wheel, positioning wheel, and redirecting roller surfaces are effectively improved by setting a silane coating, further enhancing the practicality of the device.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. By using a tensioning wheel in conjunction with a positioning wheel, a redirecting roller, and a tensioning assembly, the rubber raw material belt can easily move from one processing step to the next, bypassing the bottom of the tensioning wheel and the top of the positioning wheel, and passing between the two redirecting rollers. It then moves centrally along the guiding direction of the two redirecting rollers under the influence of gravity. Simultaneously, the tensioning assembly pushes the tensioning wheel to contact the middle section of the rubber raw material belt, maintaining its tension and reducing the risk of loosening and shifting. This effectively improves the stability of the rubber raw material belt's movement between processing steps and enhances its production quality.

[0025] 2. By setting up an adjustment mechanism in conjunction with the contact screw and drive sleeve, when the adjustment mechanism is activated to drive the drive sleeve to rotate, the drive sleeve is threadedly connected to the contact screw, which in turn pushes the contact screw to cause the contact plate to contact the tension spring. This pushes the tension spring to move towards the tension plate, thereby changing the spring's rebound stroke and adjusting the tension strength of the tension wheel to adapt to rubber material belts of different thicknesses, further improving the applicability of the device.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a rubber belt redirection device for vulcanizing flexible rubber roller sleeves.

[0034] Reference Figures 1-3 A rubber belt redirection device for vulcanizing flexible rubber roller sleeves includes a mounting base 1. One end of the mounting base 1 is provided with a tensioning groove 2. A tensioning slider 3 is slidably connected inside the tensioning groove 2. One end of the tensioning slider 3 is rotatably connected with a tensioning wheel 4. One end of the mounting base 1 is symmetrically rotatably connected with positioning wheels 5. The tensioning wheel 4 is installed between the two positioning wheels 5. A rubber raw material belt 6 is wound around one end of the tensioning wheel 4 and the positioning wheel 5. One end of the mounting base 1 is symmetrically provided with a slant frame 7. One end of the slant frame 7 is rotatably connected with a redirection roller 8. The output end of the rubber raw material belt 6 passes between the two redirection rollers 8. A tensioning component is installed at one end of the mounting base 1.

[0035] The tensioning assembly includes a tensioning slide bar 9 symmetrically fixedly connected to one end of the mounting base 1, a tensioning slider 3 with one end passing through the tensioning groove 2 and fixedly connected to a tensioning slide plate 10, a tensioning slide plate 10 with one end slidably connected to the tensioning slide bar 9, a tensioning spring 11 sleeved on one end of the tensioning slide bar 9, and the tensioning spring 11 installed between the tensioning slide plate 10 and the mounting base 1.

[0036] In the production of flexible rubber roller sleeves for printers, the rubber raw material strip 6 typically requires vulcanization. During vulcanization, the mounting base 1 is placed between two adjacent machine frames. As the processed rubber raw material strip 6 is transferred from one frame to another, one end of the strip is guided around the bottom of the tension wheel 4 and the top of the two positioning wheels 5, then passes between the two redirecting rollers 8, and finally enters the next frame for processing. Simultaneously, the rubber raw material strip 6 is centered along the guiding direction of the two redirecting rollers 8 under gravity to adjust its movement direction and reduce any deviation.

[0037] Simultaneously, when the rubber material belt 6 loosens during its movement, the force on the tension spring 11 changes. Utilizing the elastic properties of the tension spring 11, it rebounds and pushes out the tension slide plate 10, which in turn pushes the tension slide plate 10 to move the tension slider 3 and the tension wheel 4 along the length of the tension slide rod 9. This causes one end of the tension wheel 4 to push the middle section of the rubber material belt 6 along the length of the tension slide rod 9, so that the loose part of the rubber material belt 6 is stretched and tightened by the tension wheel 4, maintaining the movement of the rubber material belt 6 and further reducing the possibility of the rubber material belt 6 shifting.

[0038] Reference Figure 2 and Figure 4One end of the mounting base 1 is provided with a pair of adjusting slide grooves 12. The two adjusting slide grooves 12 are rotatably connected to the inside of the two adjusting slide grooves 12. One end of the adjusting rod 13 is provided with a threaded groove with opposite rotation direction. One end of the adjusting rod 13 passes through the mounting base 1 and is fixedly connected to the adjusting handle 14. One end of the inclined bracket 7 is slidably connected inside the adjusting slide groove 12 and threadedly connected to the adjusting rod 13.

[0039] In use, rotating the adjustment handle 14 can drive the adjustment rod 13 to rotate, and drive the adjustment rod 13 to form a threaded connection with the two inclined frames 7 in sync. This drives the two inclined frames 7 to move the two redirecting rollers 8 along the length of the adjustment groove 12, making it easier to adjust the distance between the two redirecting rollers 8 and effectively improving the applicability of the device.

[0040] Reference Figures 1-3 One end of each of the two tensioning slide rods 9 is slidably fitted with an abutting slide plate 15, which abuts against one end of the tensioning spring 11. The top of the abutting slide plate 15 is rotatably connected to an abutting screw 16. One end of the mounting base 1 is rotatably connected to a driving sleeve rod 17, which is threadedly connected to one end of the abutting screw 16. One end of the mounting base 1 is equipped with an adjustment mechanism.

[0041] The adjustment mechanism includes a bevel gear 18 fixedly connected to one end of the drive sleeve 17, a bevel gear 19 rotatably connected to one end of the mounting base 1 and meshing with the bevel gear 18, an adjustment motor 20 fixedly connected to one end of the mounting base 1, the output end of the adjustment motor 20 fixedly connected to the bevel gear 19, and a guide component installed at one end of the mounting base 1.

[0042] Furthermore, the guide assembly includes a guide groove 21 formed at one end of the mounting base 1, and a guide slider 22 is slidably connected inside the guide groove 21. The guide slider 22 is rotatably connected to the abutting screw 16.

[0043] In use, starting the adjusting motor 20 drives the bevel gear 2 19 to mesh with the bevel gear 1 18, and drives the drive sleeve 17 to rotate. At the same time, the drive sleeve 17 and the contact screw 16 are threaded together, thereby pushing the contact screw 16 to move the contact slide plate 15 along the length direction of the guide slide groove 21. Simultaneously, the contact slide plate 15 compresses the tension spring 11 along the length direction of the tension slide rod 9, causing deformation. This adjusts the deformation stroke of the tension spring 11, thereby adjusting the elastic strength of the tension spring 11 and completing the automatic adjustment of the tension strength of the tension wheel 4, further improving the applicability of the device.

[0044] Reference Figure 1 and Figure 2 The outer sides of both the positioning wheel 5 and the tensioning wheel 4 are fixedly connected to the limit plate 23.

[0045] When in use, when one end of the traction rubber material belt 6 passes over the tension wheel 4 and the positioning wheel 5, one end of the rubber material belt 6 comes into contact with the limiting disc 23 and is embedded between the redirecting roller 8, the tension wheel 4, and the positioning wheel 5, thereby limiting and guiding one end of the rubber material belt 6, which effectively reduces the possibility of the rubber material belt 6 detaching from one end of the tension wheel 4 and the positioning wheel 5, and improves the practicality of the device.

[0046] Reference Figure 1 and Figure 2 The surfaces of tensioning wheel 4, positioning wheel 5, and redirecting roller 8 are all coated with silane coating.

[0047] During use, by coating the surfaces of the tensioning wheel 4, positioning wheel 5, and redirecting roller 8 with a silane coating, a wear-resistant protective layer is formed on the surfaces of the tensioning wheel 4, positioning wheel 5, and redirecting roller 8. This effectively improves the anti-stick properties of the surfaces of the tensioning wheel 4, positioning wheel 5, and redirecting roller 8, thus enhancing the practicality of the device.

[0048] The implementation principle of the rubber belt redirection device for vulcanizing flexible rubber roller sleeves in this embodiment is as follows: During the production of flexible rubber roller sleeves for printers, the mounting base 1 is first placed between the frames of two adjacent processes. During the process of importing the rubber raw material belt 6 processed from one frame into another, one end of the rubber raw material belt 6 is guided to pass around the bottom of the tension wheel 4 and the top of the two positioning wheels 5, then passes between the two redirection rollers 8, and finally enters the next frame for processing. Simultaneously, the rubber raw material belt 6 moves centered along the guiding direction of the two redirection rollers 8 under the action of gravity, thereby adjusting the movement direction of the rubber raw material belt 6 and reducing the possibility of deviation.

[0049] Simultaneously, when the rubber material belt 6 loosens during its movement, the force on the tension spring 11 changes. Utilizing the elastic properties of the tension spring 11, it rebounds and pushes out the tension slide plate 10, which in turn pushes the tension slide plate 10 to move the tension slider 3 and the tension wheel 4 along the length of the tension slide bar 9. This causes one end of the tension wheel 4 to push the middle section of the rubber material belt 6 along the length of the tension slide bar 9, so that the loose part of the rubber material belt 6 is stretched and tightened by the tension wheel 4, maintaining the movement of the rubber material belt 6 and further reducing the possibility of the rubber material belt 6 shifting.

[0050] Then, when the thickness of the rubber raw material belt 6 changes, the adjustment motor 20 can be activated to drive the bevel gear 2 19 to mesh with the bevel gear 1 18, and drive the drive sleeve 17 to rotate. At the same time, the drive sleeve 17 and the contact screw 16 are threaded together, thereby pushing the contact screw 16 to move the contact slide plate 15 along the length direction of the guide slide groove 21. Simultaneously, the contact slide plate 15 is pressed along the length direction of the tension slide rod 9 to deform the tension spring 11, thereby adjusting the deformation stroke of the tension spring 11 and adjusting the elastic strength of the tension spring 11. This completes the automatic adjustment of the tension strength of the tension wheel 4 to adapt to rubber raw material belts 6 of different thicknesses.
