Description

Technical Field

[0001] This utility model belongs to the field of paper production technology, specifically a paper calender. Background Technology

[0002] Calenders are like professional tools that "iron" and "beautify" materials. Through gentle pressure and temperature, they smooth out the roughness of the surface of sheet materials such as paper and film, giving them a smooth, shiny "coat" that enhances both the appearance and practicality of the materials.

[0003] Currently, operators frequently need to use calenders when processing paper. Although existing calenders have basic calendering functions, they cannot calender paper of different thicknesses. Therefore, when operators need to calender paper of different thicknesses, the calenders cannot meet the operational requirements, thus narrowing their application scope. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a paper calender that has the advantage of wide application range.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper calender, comprising a base, with a first connecting plate and a second connecting plate fixedly connected to the front and rear directions of the right side of the top of the base, respectively. A movable block and a moving block are movably connected to the top of the first and second connecting plates, respectively. A lower pressure roller is movably installed inside the top of the second connecting plate, with its front end passing through the second connecting plate and extending to the back of the first connecting plate, and movably connected to the back of the first connecting plate. An upper pressure roller is movably installed between the interiors of the movable block and the moving block. A servo motor is fixedly installed on the back of the base, with a rotating shaft fixedly sleeved at the other end of the servo motor's output shaft. A hollow block is fixedly connected to the other end of the rotating shaft, and a round shaft is movably connected inside the hollow block. The other end of the round shaft is fixedly connected to the bottom end of the back of the moving block.

[0006] As a preferred embodiment of this utility model, a drive motor is fixedly installed on the front side of the first connecting plate, and a rotating shaft is fixedly sleeved on the other end of the output shaft of the drive motor. The other end of the rotating shaft passes through the first connecting plate and extends to the front side of the lower pressing roller and is fixedly connected to the front side of the lower pressing roller. The outer surface of the rotating shaft is movably connected to the interior of the first connecting plate.

[0007] As a preferred embodiment of this utility model, the top ends of both the first connecting plate and the second connecting plate are fixedly connected to guide plates located inside the movable block and the moving block, and there are two guide plates. The outer surfaces of the two guide plates are respectively movably connected to the interior of the movable block and the moving block.

[0008] As a preferred embodiment of this utility model, a long plate located to the left of the movable block is movably connected to the front of the top of the base, and the right side of the long plate is movably connected to the left side of the movable block and the first connecting plate. A rectangular plate located to the left of the moving block is fixedly installed at the rear of the top of the base, and the right side of the rectangular plate is movably connected to the left side of the moving block and the second connecting plate. A first cleaning roller is movably connected between the bottom ends of the long plate and the rectangular plate.

[0009] As a preferred embodiment of this utility model, the top ends of both the long plate and the rectangular plate are movably connected to limit blocks, and there are two limit blocks. A second cleaning roller is movably connected between the interiors of the two limit blocks.

[0010] As a preferred embodiment of this utility model, each of the two limiting blocks is fixedly connected to a spring at its top end, and there are two springs in total. The top ends of the two springs are respectively fixedly connected to the interior of the long plate and the rectangular plate.

[0011] As a preferred embodiment of this utility model, a circular block is fixedly connected to the left side of the top front of the base, a rotating block is movably installed on the outer surface of the circular block, and a threaded shaft is movably installed inside the rotating block. One end of the threaded shaft passes through the rotating block and extends to the inside of the bottom end of the long plate and engages with the internal thread of the long plate. The other end of the threaded shaft passes through the rotating block and extends to the outside of the front of the rotating block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a servo motor, a rotating shaft, a hollow block, and a round shaft, allows the operator to start the servo motor, which will cause the rotating shaft and the hollow block to rotate. This causes the inner surface of the hollow block to press and push the outer surface of the round shaft, which in turn causes the round shaft to drive the moving block, the upper pressure roller, and the movable block to move upward. This increases the distance between the upper pressure roller and the lower pressure roller, allowing the operator to place paper of a corresponding thickness between the lower pressure roller and the upper pressure roller according to the adjusted height, thereby increasing the application range of the calender.

[0013] 2. By setting up a circular block, a rotating block, and a threaded shaft, when the operator rotates the threaded shaft, the other end of the threaded shaft will disengage from the inside of the long plate, thereby releasing the fixing effect on the long plate. At this time, the operator can remove the long plate from the front of the first and second cleaning rollers. Then, the operator can remove the first and second cleaning rollers in sequence, thereby replacing the first and second cleaning rollers and avoiding a reduction in cleaning efficiency.

[0016] 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.

[0017] like Figures 1 to 6As shown, this utility model provides a paper calender, including a base 1. A first connecting plate 2 and a second connecting plate 3 are fixedly connected to the front and rear directions of the right side of the top of the base 1, respectively. A movable block 4 and a moving block 5 are movably connected to the top of the first connecting plate 2 and the second connecting plate 3, respectively. A lower pressing roller 6 is movably installed inside the top of the second connecting plate 3. The front of the lower pressing roller 6 passes through the second connecting plate 3 and extends to the back of the first connecting plate 2 and is movably connected to the back of the first connecting plate 2. An upper pressing roller 7 is movably installed between the interior of the movable block 4 and the moving block 5. A servo motor 8 is fixedly installed on the back of the base 1. A rotating shaft 9 is fixedly sleeved on the other end of the output shaft of the servo motor 8. A hollow block 10 is fixedly connected to the other end of the rotating shaft 9. A round shaft 11 is movably connected inside the hollow block 10. The other end of the round shaft 11 is fixedly connected to the bottom end of the back of the moving block 5.

[0018] When the operator starts the servo motor 8, the rotating shaft 9 and the hollow block 10 will rotate. This will cause the inner surface of the hollow block 10 to press and push the outer surface of the round shaft 11, which will cause the round shaft 11 to drive the moving block 5, the upper calendering roller 7 and the movable block 4 to move upward. This will enable the upper calendering roller 7 and the lower calendering roller 6 to perform calendering operations on paper of different thicknesses.

[0019] Among them, a drive motor 12 is fixedly installed on the front side of the first connecting plate 2, and a rotating shaft 13 is fixedly sleeved on the other end of the output shaft of the drive motor 12. The other end of the rotating shaft 13 passes through the first connecting plate 2 and extends to the front side of the lower pressing roller 6 and is fixedly connected to the front side of the lower pressing roller 6. The outer surface of the rotating shaft 13 is movably connected to the interior of the first connecting plate 2.

[0020] When the operator starts the drive motor 12, the rotating shaft 13 and the pressing roller 6 will rotate.

[0021] Among them, the top of the first connecting plate 2 and the second connecting plate 3 are fixedly connected to the guide plate 14 located inside the movable block 4 and the moving block 5. There are two guide plates 14, and the outer surfaces of the two guide plates 14 are respectively movably connected to the interior of the movable block 4 and the moving block 5.

[0022] Due to the design of the two guide plates 14, the movement of the movable block 4 and the moving block 5 can be effectively limited.

[0023] Among them, a long plate 15 located to the left of the movable block 4 is movably connected to the front of the top of the base 1. The right side of the long plate 15 is movably connected to the left side of the movable block 4 and the first connecting plate 2. A rectangular plate 16 located to the left of the moving block 5 is fixedly installed at the rear of the top of the base 1. The right side of the rectangular plate 16 is movably connected to the left side of the moving block 5 and the second connecting plate 3. A first cleaning roller 17 is movably connected between the bottom of the long plate 15 and the rectangular plate 16.

[0024] Due to the design of the first cleaning roller 17, dust and paper scraps adhering to the outer surface of the paper can be adhered to it.

[0025] The top of both the long plate 15 and the rectangular plate 16 are movably connected to limit blocks 18. There are two limit blocks 18, and a second cleaning roller 20 is movably connected between the interior of the two limit blocks 18.

[0026] Due to the design of the limiting block 18, it provides a good guiding effect for the subsequent movement of the second cleaning roller 20.

[0027] Two springs 19 are fixedly connected to the top of each of the two limiting blocks 18. The tops of the two springs 19 are fixedly connected to the interior of the long plate 15 and the rectangular plate 16, respectively.

[0028] The design of the two springs 19 effectively resets the movement of the two limit blocks 18.

[0029] Among them, a round block 21 is fixedly connected to the left side of the top front of the base 1. A rotating block 22 is movably installed on the outer surface of the round block 21. A threaded shaft 23 is movably installed inside the rotating block 22. One end of the threaded shaft 23 passes through the rotating block 22 and extends to the inside of the bottom end of the long plate 15 and is threaded with the inside of the long plate 15. The other end of the threaded shaft 23 passes through the rotating block 22 and extends to the outside of the front of the rotating block 22.

[0030] When the other end of the threaded shaft 23 is inside the long plate 15, it will have a fixing effect on the long plate 15.

[0031] Working principle and usage process of this utility model: First, the operator starts the servo motor 8 according to the thickness of the paper to be matted, driving the rotating shaft 9 and the hollow block 10 to rotate. The inner surface of the hollow block 10 then presses and pushes the outer surface of the round shaft 11, causing the round shaft 11 to drive the moving block 5, the upper pressure roller 7, and the movable block 4 upward. This increases the distance between the bottom of the outer surface of the upper pressure roller 7 and the top of the outer surface of the lower pressure roller 6, ensuring that the lower pressure roller 6 and the upper pressure roller 7 can subsequently adapt to the paper to complete the calendering operation. Then, the operator starts the drive motor 12, causing the rotating shaft 13 and the lower pressure roller 6 to rotate. Simultaneously rotating, the paper passes between the first cleaning roller 17 and the second cleaning roller 20 for cleaning. During this process, the second cleaning roller 20 drives the two limit blocks 18 to move upward due to the reaction force, while the two springs 19 are compressed. Then the paper enters between the lower pressure roller 6 and the upper pressure roller 7. The rotation of the lower pressure roller 6 drives the paper to move to the right, while the upper pressure roller 7 is driven to rotate by the paper under the action of friction. At the same time, the first cleaning roller 17 and the second cleaning roller 20 also rotate synchronously to adhere and clean the dust and paper scraps on the outer surface of the paper.

[0032] Finally, when the first cleaning roller 17 and the second cleaning roller 20 need to be replaced due to long-term use, the operator rotates the threaded shaft 23 to disengage its other end from the inside of the long plate 15, releases the fixation of the long plate 15, and removes it from the front of the first cleaning roller 17 and the second cleaning roller 20. Then, the first cleaning roller 17 and the second cleaning roller 20 are removed in sequence, which can achieve quick and convenient replacement of the first cleaning roller 17 and the second cleaning roller 20.
