[0036] 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.

[0037] Reference Figures 1-2This utility model provides an embodiment of an anti-wrinkle adjustable pressure roller mounting machine, including a mounting machine 1. The mounting machine 1 is the core equipment for cardboard processing, which can achieve precise bonding of corrugated paper and face paper. Its body is welded from high-strength steel, which makes it stable in operation and not prone to vibration. A support plate 2 is fixedly connected to the upper part of the mounting machine 1, and an adjustment mechanism 3 is provided on the outer wall of the support plate 2. The support plate 2 is fixed to the upper part of the mounting machine 1 by welding. It is made of thick steel plate, which has strong structural rigidity and can provide stable support for the adjustment mechanism 3.

[0038] Reference Figure 2 , Figure 4 and Figure 5 The adjusting mechanism 3 includes a guide plate 301 fixedly connected to the outer wall of the support plate 2. A movable plate 303 is slidably connected to the outer wall of the guide plate 301. The guide plate 301 is welded and fixed to the outer wall of the support plate 2, restricting the movable plate 303 to move only in the horizontal direction. The inner wall of the guide plate 301 is coated with grease to reduce frictional wear with the movable plate 303. A moving plate 304 is fixedly connected to the bottom of the movable plate 303. The movable plate 303 is made of lightweight alloy material, with a very small sliding gap with the guide plate 301, allowing for smooth movement and precise positioning. It can drive the moving plate 304 to rise and fall synchronously, thereby adjusting the height of the pressure roller 5. A connector is provided at the top front side, which can drive the two sets of movable plates 303 to move synchronously. A fixing component 302 is provided on the inner side wall of the mounting machine 1. The fixing component 302 can provide stable driving force and locking force for the movable plates 303. The movable plates 303 are accurately raised and lowered through threaded transmission. A vertical plate 308 is fixedly connected to the outer wall of the support plate 2. A movable column 306 is slidably connected to the outer wall of the vertical plate 308. The vertical plate 308 is welded and fixed to the outer wall of the support plate 2 and is vertically distributed to provide vertical sliding support for the movable column 306, ensuring that the movable column 306 always remains parallel to the paperboard conveying direction when it moves.

[0039] Furthermore, a rotating column 309 is rotatably connected to the side of the movable column 306 away from the support plate 2. The outer arc surface of the rotating column 309 is detachably mounted with a pressure roller 5 via a disassembly mechanism 4. The rotating column 309 is rotatably connected to the movable column 306 via a precision bearing, ensuring smooth rotation without jamming. This allows the pressure roller 5 to rotate synchronously, resulting in rolling friction between the pressure roller 5 and the cardboard, reducing cardboard wear. The disassembly mechanism 4 facilitates quick replacement and maintenance of the pressure roller 5, adapting to the needs of pressure rollers 5 with different textures and diameters. The guide plate 301 has a concave cross-section, which makes the sliding of the movable plate 303 more stable. The two sides of the concave shape can prevent the movable plate 303 from shifting left and right, ensuring the precise lifting trajectory of the pressure roller 5. The concave structure can also protect the sliding parts and reduce the entry of dust and debris. The connecting parts include a connecting plate 305 fixedly connected to the upper part of the movable plate 303. A set of connecting plates 305 can drive two sets of movable plates 303 to move synchronously.

[0040] Reference Figures 3-5 The fixing component 302 includes a fixing plate 3021 fixedly connected to the inner side wall of the mounting machine 1. A threaded rod 3022 is threadedly connected to the inner wall of the fixing plate 3021. The fixing plate 3021 is welded and fixed to the inner side wall of the mounting machine 1. It adopts a solid steel plate structure, has high strength, and can withstand the locking force of the threaded rod 3022 without deformation. The position of the fixing plate 3021 corresponds to the movable plate 303, ensuring that the threaded rod 3022 can accurately act on the connecting plate 305. The front end of the threaded rod 3022 is rotatably connected to the rear inner wall of the connecting plate 305. Made of high-strength alloy steel, 3022 has anti-slip knobs on its surface, allowing workers to manually rotate it to move the movable plate 303 horizontally without special tools. The threaded rod 3022 has high thread precision and fits tightly with the fixed plate 3021, enabling the limiting of the connecting parts. The connecting plate 305 is welded and fixed to the movable plate 303. The front end of the threaded rod 3022 is rotatably connected to the connecting plate 305 through a bearing, so that the rotational motion of the threaded rod 3022 is converted into the linear motion of the movable plate 303, preventing the threaded rod 3022 from driving the movable plate 303 to rotate.

[0041] Furthermore, a guide groove is formed on the outer wall of the movable plate 304. The outer arc surface of the movable column 306 contacts the interior of the guide groove. The inner wall of the guide groove on the outer wall of the movable plate 304 is smooth and has a high degree of fit with the outer arc surface of the movable column 306. This provides horizontal guidance for the movable column 306 and restricts its vertical displacement, ensuring the stability of the pressure roller 5. Two sets of positioning plates 307 are fixedly connected to the outer arc surface of the movable column 306. The sides of the two sets of positioning plates 307 that are close to each other are in contact with the outer wall of the movable plate 304. The two sets of positioning plates 307 are welded and fixed to the movable column 306 and are symmetrically distributed on both sides of the movable plate 304. This clamps the movable plate 304 and restricts the relative sliding between the movable column 306 and the movable plate 304, ensuring the stability of the pressure roller 5. The inner wall of the positioning plate 307 is smooth and does not affect the horizontal movement of the movable column 306 along the guide groove.

[0042] Reference Figure 6The disassembly mechanism 4 includes a mounting plate 401 fixedly connected to the outer arc surface of the rotating column 309. Two sets of mounting plates 401 are provided and are symmetrically installed on the upper and lower sides of the rotating column 309. A mounting block 402 is fixedly connected to the side of the pressure roller 5 facing the positioning plate 307. The mounting block 402 is integrally formed with the pressure roller 5 and is made of hard alloy material. It can withstand the pressure and torque of the pressure roller 5 during operation and evenly transmit the force to the rotating column 309. The size of the mounting block 402 matches the mounting plate 401 to ensure that the axis of the pressure roller 5 coincides with the axis of the rotating column 309 after installation. The inner wall of the mounting block 402 can be detachably installed on the outer wall of the mounting plate 401 by bolts 404. The bolts 404 are high-strength stainless steel bolts 404, and the threaded connection is firm, which can tightly fix the mounting block 402 to the mounting plate 401 and prevent the pressure roller 5 from loosening when rotating at high speed.

[0043] Furthermore, a square groove 405 is provided on the side of the mounting block 402 facing the rotating column 309. The fit clearance between the square groove 405 and the mounting plate 401 is extremely small. After the mounting plate 401 is inserted into the square groove 405, it can restrict the circumferential rotation of the pressure roller 5, preventing the bolt 404 from being damaged due to bearing torque alone. The inner wall of the square groove 405 is milled flat to improve the fit. A round hole 403 is provided on the upper part of the mounting block 402. The cross-section of the mounting plate 401 is set in an L shape. The L-shape facilitates insertion and positioning. The mounting plate 401 is close to One end of the pressure roller 5 is inserted into the inner wall of the square groove 405. The connection method of inserting the mounting plate 401 into the square groove 405 makes the connection between the mounting block 402 and the mounting plate 401 tighter. At the same time, it shares some of the pressure on the bolt 404 and extends the service life of the bolt 404. The inner arc surface of the round hole 403 is larger than the thread surface of the bolt 404. The round hole 403 provides an installation channel for the bolt 404. Its inner diameter is larger than the thread surface of the bolt 404, which facilitates the quick insertion of the bolt 404 without the need for precise alignment of the threaded hole, thus reducing the installation difficulty.

[0044] Working principle: Before operation, adjust the height of the pressure roller 5 according to the thickness of the cardboard. Rotate the threaded rod 3022 of the fixed component 302, and drive the connecting plate 305 through the threaded transmission to move the two sets of movable plates 303 horizontally along the concave guide plate 301. The movable plate 303 drives the moving plate 304 to move synchronously. The guide groove of the moving plate 304, together with the positioning plate 307, guides the movable column 306 to move up and down, thereby adjusting the pressure roller 5 to the appropriate height. The self-locking property of the threaded connection ensures that the height of the pressure roller 5 is locked. During operation, the mounting machine 1 conveys corrugated paper and face paper. The rotating column 309 drives the pressure roller 5 to roll and press the cardboard. The rolling friction reduces the wear of the cardboard. The pressure of the pressure roller 5 makes the two papers adhere together without wrinkles. The vertical plate 308 provides vertical support for the movable column 306, ensuring that the pressure roller 5 is always parallel to the cardboard conveying direction, further ensuring the bonding accuracy.

[0045] When the pressure roller 5 needs to be replaced, unscrew the bolt 404 of the disassembly mechanism 4, remove the mounting block 402 from the L-shaped mounting plate 401, and the new pressure roller 5 is positioned by inserting it into the mounting plate 401 through the square groove 405 of the mounting block 402. Then, fix it with the bolt 404 to quickly complete the replacement. The overall structure of the pressure roller 5, which can be precisely adjusted, and the convenient disassembly and assembly design are suitable for processing different specifications of cardboard, ensuring the anti-wrinkle effect and processing efficiency of the mounting operation.

[0046] 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.
