Description

Technical Field

[0001] This utility model relates to the field of rubber roller forming tension adjustment, and in particular to a rubber roller forming tension control device. Background Technology

[0002] Rubber rollers are roll-shaped products made with a metal or other material core covered with rubber through vulcanization. They are widely used in many fields such as papermaking, printing, textiles, and plastics processing. Because different industries and production stages have varying requirements for the shape, size, hardness, surface roughness, elasticity, and other properties of rubber rollers, a molding process is necessary to give them specific structures and properties that meet the actual application needs. Only through molding can rubber rollers, with precise specifications and stable performance, complete tasks such as material transfer, pressure application, and surface treatment in production, realizing their functional value in various industrial processes.

[0003] Rubber rollers are typically formed using a rubber-coating method. First, the metal mandrel is surface-treated to enhance its bonding strength with the rubber. Then, the mixed rubber is extruded into tubular or sheet shapes using an extruder. Next, a rubber-coating machine tightly winds the rubber sheets onto the mandrel in sequence. During this process, a conveyor roller is used for transport. However, during the transport process, changes in speed will cause changes in the tension of the rubber sheet. These tension changes will cause the rubber sheet to be subjected to uneven tension during transport, which in turn will affect the smoothness and tightness of the subsequent rubber coating.

[0004] Therefore, it is necessary to provide a new rubber roller forming tension control device to solve the above-mentioned technical problems. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 3 A rubber roller forming tension control device includes: a base plate 1, which can be placed stably on the working ground and bear the weight of the components above. An extruder 2 is fixedly connected to the top of the base plate 1. The extruder 2 is a key piece of equipment for rubber sheet forming, and its main body consists of a barrel, screw, heating device and other parts. The barrel is used to hold the mixed rubber raw materials. The screw rotates inside the barrel under the drive of the motor, pushing the rubber forward and performing plasticizing and melting operations. The heating device provides the heat required for the plasticizing of the rubber, so that it can be smoothly extruded into a sheet with a certain thickness and width. A support plate 3 is fixedly connected to the rear side of the base plate 1. The support plate 3 is perpendicular to the base plate 1 and plays a supporting and positioning role. The front side of the support plate 3 away from the base plate 1 is rotatably connected to the first guide roller 4 to reduce the friction of the sheet during the conveying process. The front side of the support plate 3 away from the base plate 1 and diagonally opposite to the first guide roller 4 is rotatably connected to the second guide roller 5 to further adjust the conveying path of the sheet. The top of the support plate 3 is fixedly connected to the receiving block 6. The right front side of the receiving block 6 is provided with a movable groove 7. The inside of the movable groove 7 is rotatably connected to the connecting rod 8. The front end of the connecting rod 8 is rotatably connected to the adjusting roller 9, so that the adjusting roller 9 can be adjusted in angle within the movable groove 7.

[0023] The adjusting assembly is installed inside the top of the connecting rod 8. The adjusting assembly includes a rotating rod 10, to which a rotating gear 11 is fixedly connected. An electric push rod 12 is fixedly connected inside the left side of the receiving block 6. The electric push rod 12 is a drive device that converts electrical energy into mechanical energy. A rack plate 13 is fixedly connected to the drive end of the electric push rod 12. The rack plate 13 is a long strip-shaped component with a rack machined on one side. The rotating gear 11 and the rack plate 13 are meshed together, and through this meshing transmission method, the linear motion of the electric push rod 12 is converted into the rotational motion of the rotating gear 11. A sliding chamber 14 is formed inside the right side of the receiving block 6. The shape and size of the sliding chamber 14 match the rack plate 13, providing stable sliding guidance for the rack plate 13. The outer side of the rack plate 13 is slidably connected to the inner wall of the sliding chamber 14, allowing the rack plate 13 to remain stable during sliding. A rotating chamber 15 is provided on the right side of the receiving block 6 above the rack plate 13. The rotating chamber 15 provides rotation space for the rotating gear 11. Its inner wall is finely machined to ensure the flexible rotation of the rotating gear 11. The outer side of the rotating gear 11 is rotatably connected to the inner wall of the rotating chamber 15.

[0024] A vertical plate 16 is fixedly connected to the right side of the receiving block 6. The vertical plate 16 is perpendicular to the receiving block 6 and serves as a support. Two transmission rods 17 are rotatably connected inside the bottom end of the vertical plate 16. The transmission rods 17 are mounted on the vertical plate 16 via bearings and can rotate freely. A transfer roller 18 is fixedly connected to the outside of the transmission rods 17. The transfer roller 18 consists of a roller body and the transmission rods 17. The surface of the roller body has a certain roughness to increase the friction between it and the film, ensuring stable film transfer. The rear side of the transfer roller 18 is rotatably connected to the front bottom end of the vertical plate 16 to ensure its rotational stability. A transmission gear 19 is fixedly connected to the rear side of the transmission rod 17, and a motor 20 is fixedly connected to the rear top of the upright plate 16. The two transmission gears 19 are meshed. The rear end of the bottom transmission gear 19 is fixedly connected to the drive end of the motor 20. The rotation of the motor 20 drives the bottom transmission gear 19, and then drives the other transmission gear 19 through meshing transmission, thereby realizing the synchronous rotation of the two transmission rollers 18, and continuously and stably conveying the film forward.

[0025] The working principle of the rubber roller forming tension control device provided by this utility model is as follows:

[0026] First, the extruder 2 is started. After the mixed rubber undergoes plasticizing and melting processes in the extruder 2, it is extruded into a sheet with a certain thickness and width. After the extruded sheet comes out of the extruder 2, it first contacts the first guide roller 4 on the front side of the support plate 3. Under the guidance of the first guide roller 4, the sheet changes its direction of movement so that it can move smoothly towards the second guide roller 5. The sheet continues to move and reaches the second guide roller 5, where it changes its direction again.

[0027] When the film reaches the vicinity of the receiving block 6, the adjustment assembly begins to function. The electric push rod 12 is activated, and its drive end pushes the rack plate 13 to slide within the sliding chamber 14. Since the rack plate 13 is meshed with the rotating gear 11, as the rack plate 13 moves, the rotating gear 11 begins to rotate within the rotating chamber 15.

[0028] The rotating gear 11 is fixed to the rotating rod 10, which rotates accordingly. The rotating rod 10 is connected to the connecting rod 8, thereby causing the connecting rod 8 and the adjusting roller 9 to rotate a certain angle within the movable groove 7. By changing the position of the adjusting roller 9, forces of different directions and magnitudes are applied to the film, thereby adjusting the tension of the film. For example, when the film tension is too high, the adjusting roller 9 can appropriately reduce the tension on the film; when the film tension is too low, the adjusting roller 9 can increase the tension on the film, ensuring that the film tension is within the appropriate range when it enters the subsequent transmission stage.

[0029] After tension adjustment, the film continues to move to the right and reaches the transmission roller 18 at the upright plate 16. At this time, the motor 20 is started. The drive end of the motor 20 drives the bottom transmission gear 19, which is fixedly connected to it, to rotate. Since the two transmission gears 19 are meshed, the other transmission gear 19 will also rotate. The transmission gear 19 is fixed on the transmission rod 17. The rotation of the transmission rod 17 drives the transmission roller 18 to rotate. The rotation of the transmission roller 18 continuously and stably conveys the film forward, preparing it for subsequent winding of the film onto the metal mandrel for rubber roller coating molding.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
