Description

Technical Field

[0001] This utility model relates to the field of calendering machine technology, and in particular to a calendering roller interval adjustment structure. Background Technology

[0002] Calendering, as an important material forming and processing technology, is widely used in various industrial fields such as metal sheets, plastic films, rubber products, paper, and textile coatings. Its core principle is to apply high pressure to the material using one or more pairs of rotating pressure rollers, causing plastic deformation or achieving specific thicknesses, surface finishes, and structural density requirements. In this process, the working gap (or roll gap) between the two pressure rollers is a key process parameter determining the thickness, precision, and surface quality of the final product. Traditional technologies, while achieving precise vertical (up-down) displacement, cannot restrict undesirable horizontal movement (especially in the front-back direction). Simple screw-driven or shim-based adjustments cannot achieve continuous, precise online adjustment, making it difficult to guarantee the parallelism of the two rollers. Utility Model Content

[0003] The purpose of this invention is to provide a structure for adjusting the interval of calendered rollers to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A calendering roller spacing adjustment structure includes:

[0006] The fixing base has a first mounting hole that runs vertically through the top, a second mounting hole that runs horizontally through the left side, and a first clearance hole that runs front to back through the front.

[0007] The first pressure roller passes through the inner bottom end of the second mounting hole, and the right end of the first pressure roller is fixedly installed inside the second mounting hole of the fixed base.

[0008] A fixing module is provided, and multiple fixing modules are provided. The fixing modules are symmetrically arranged on the left side of the fixing seat. The fixing modules are used to fix the left end of the first pressure roller.

[0009] The second pressure roller passes through the inner top end of the second mounting hole of the fixed base. A first limiting block is fixedly installed on the top of the second pressure roller. Multiple first limiting blocks are provided. The first limiting blocks are symmetrically arranged in the second mounting hole. A second limiting block is fixedly installed on the side of the first limiting blocks that are close to each other. The first limiting blocks are slidably installed in the second mounting hole of the fixed base.

[0010] A sliding module is provided, and multiple sliding modules are provided. The sliding modules are symmetrically arranged at the front and rear ends on the left and right sides of the fixed base. The sliding modules are used to limit the movement position of the second pressure roller.

[0011] The lifting module is fixedly installed on the top of the fixed base and is used to drive the second pressure roller to move up and down.

[0012] By adopting the above technical solution, the first pressure roller is horizontally leveled and fixed by the fixing module, and the second pressure roller is vertically moved and fixed by the sliding module. The horizontal adjustment of the second pressure roller can be adjusted. The second pressure roller can be moved vertically by the lifting module to achieve more precise continuous movement. The second pressure roller is restricted inside the fixed seat by the first limit block and the second limit block, so that it cannot move in the forward and backward direction, thereby controlling the distance between the first pressure roller and the second pressure roller to meet the required requirements.

[0013] In a further embodiment, the fixing module includes:

[0014] A base, which is fixedly installed on the left side of a fixed seat;

[0015] The bearing housing is fixedly installed on the left side of the base. The top of the bearing housing has a second clearance hole that runs vertically through it, and a rotating shaft passes through the second clearance hole.

[0016] The first clamping rod has one end rotatably mounted on a rotating shaft, and the bottom end of the first clamping rod is fixedly mounted with one end of a plurality of first round rods;

[0017] The first clamping block is rotatably mounted on the rotating shaft. The first clamping block is located at the bottom of the first clamping rod. The top of the first clamping block is provided with a third clearance hole that runs vertically through it. The other end of the first round rod passes through the third clearance hole.

[0018] The second clamping block is rotatably mounted on the rotating shaft. The second clamping block is located at the bottom of the first clamping block. The bottom end of the second clamping block is provided with a fourth clearance hole that runs vertically through the shaft.

[0019] The second clamping rod has one end rotatably mounted on the rotating shaft. The second clamping rod is located at the bottom of the second clamping block. One end of the second round rod is fixedly mounted on the top of the second clamping rod. The other end of the second round rod passes through the fourth clearance hole.

[0020] The first telescopic module has its two ends rotatably mounted on the other end of the first clamping rod.

[0021] The second telescopic module has two ends that are rotatably mounted on the other end of the second clamping rod. The second telescopic module has the same structure as the first telescopic module.

[0022] In a further embodiment, the first telescopic module includes:

[0023] The third round rod has one end rotatably mounted on the other end of the first clamp rod at the left rear end of the fixed base, and the other end of the third round rod is fixedly mounted with a first nut;

[0024] The fourth round rod has a first thread at its left end that corresponds to the first nut, and a second thread at its right end. The helixes of the first thread and the second thread are in opposite directions.

[0025] The fifth round rod has one end rotatably mounted on the left front end of the fixed base, and the other end of the fifth round rod is fixedly mounted with a second nut corresponding to the second thread.

[0026] In a further embodiment, the sliding module includes:

[0027] A fixing block, wherein a clearance groove is provided on the left side of the fixing block, and the right side of the fixing block is fixedly installed on the left side of the fixing seat;

[0028] A sliding rod, one end of which is provided with an integrally formed disc, the disc being slidably installed in a clearance groove;

[0029] The movable block has a third mounting hole that extends through the left and right sides on its right side. The other end of the slide rod passes through the third mounting hole and has a third thread. A third nut is screwed onto the third thread.

[0030] In a further embodiment, the lifting module includes:

[0031] The motor, wherein multiple motors are provided, and the motors are fixedly mounted on the top of the mounting base;

[0032] The screw has a fixed connection between the motor shaft and the top of the screw. The top of the screw is provided with a fourth thread, and the bottom of the screw is provided with a fifth thread. The pitch of the fifth thread is smaller than the pitch of the fourth thread, and the helixes of the fourth thread and the fifth thread are in opposite directions.

[0033] The first sleeve passes through the first mounting hole, the top end of the screw passes through the first sleeve, and the inner wall of the first sleeve is provided with a fourth thread.

[0034] The second sleeve is fixedly installed with the first limiting block, and the bottom end of the screw passes through the second sleeve. The inner wall of the second sleeve is provided with a fifth thread.

[0035] In a further embodiment, a first fixing plate is fixedly installed at both the front and rear ends of the left side of the first pressure roller, and a second fixing plate is fixedly installed at both the front and rear ends of the left side of the second pressure roller.

[0036] By adopting the above technical solution, the right end of the first pressure roller is fixedly installed on the right side of the fixed seat with bolts. The first fixed plate at the left end of the first pressure roller is moved to the gap between the first clamping block and the first clamping rod to align the first pressure roller horizontally, ensuring that the center line of the first pressure roller is horizontal. The first nut of the third round rod and the second nut of the fifth round rod are rotated, so that the two ends of the third round rod enter the interior of the third round rod and the fifth round rod respectively. This causes the first clamping rod to rotate and move closer to each other. The first round rod at the bottom of the first clamping rod passes through the third clearance hole of the first clamping block, thereby driving the first clamping block to move closer to the first fixed plate of the first pressure roller. The second telescopic module is also driven to move the second clamping block closer to the first fixed plate of the first pressure roller. Under the action of the first and second clamping blocks, the first pressure roller is fixed. The second fixed blocks on the left and right sides of the second pressure roller move to the gap between the bearing seat and the movable block. The first limiting block is fixedly installed on the top of the second pressure roller, and the second limiting block is fixedly installed on the side of the first limiting block that is close to each other. On the side, the first and second limiting blocks restrict the second pressure roller to move only up and down, not forward, backward, left, or right. The motor drives the screw to rotate. The screw rotates once in the first sleeve, advancing the pitch of the fourth thread. The screw also rotates once in the second sleeve. Because the pitch of the fifth thread is less than the pitch of the fourth thread, and the helixes of the fourth and fifth threads are in opposite directions, the second sleeve moves relative to the screw towards the first sleeve by one pitch. Overall, relative to the motor, the second sleeve moves away from the first sleeve by the difference between the pitches of the fourth and fifth threads, thus increasing the movement accuracy of the second pressure roller and allowing for more precise control of its movement distance. When the second pressure roller reaches the corresponding position, rotating the third nut moves the movable block towards one side of the fixed seat. Under the action of the movable block and the bearing seat, the second pressure roller is fixed, thus fixing the gap between the first and second pressure rollers.

[0037] In summary, this utility model has the following beneficial effects:

[0038] 1. By setting a fourth thread at the top of the screw and a fifth thread at the bottom, with the helixes of the fourth and fifth threads pointing in opposite directions and the pitch of the fifth thread being smaller than that of the fourth thread, the screw rotates once in the first sleeve and advances the fourth thread by one pitch. Simultaneously, the screw rotates once in the second sleeve. Because the pitch of the fifth thread is smaller than that of the fourth thread, and the helixes of the fourth and fifth threads are in opposite directions, the second sleeve moves relative to the screw towards the first sleeve by one pitch. Overall, relative to the motor, the second sleeve moves away from the first sleeve by the difference between the pitches of the fourth and fifth threads, thereby increasing the movement accuracy of the second pressure roller and enabling more precise control of its movement distance.

The bottom end of the second clamping block 35 has a fourth clearance hole that runs vertically through it.

The top of the second clamping rod 36 has one end fixedly mounted on it, and the other end of the second round rod passes through the fourth clearance hole.

The second telescopic module 38 has both ends rotatably mounted on the other end of the second clamping block 36. The second telescopic module 38 has the same structure as the first telescopic module 37.

[0050] The first telescopic module 37 includes a third round rod 371, one end of which is rotatably mounted on the other end of the first clamping rod 33 at the left rear end of the fixed base 1, and the other end of which is fixedly mounted with a first nut; a fourth round rod 372, the left end of which is provided with a first thread corresponding to the first nut, and the right end of which is provided with a second thread, the spiral directions of the first thread and the second thread being opposite; and a fifth round rod 373, one end of which is rotatably mounted on the left front end of the fixed base 1, and the other end of which is fixedly mounted with a second nut corresponding to the second thread.

[0051] The sliding module 7 includes a fixed block 71, with a clearance groove on the left side of the fixed block 71 and the right side of the fixed block 71 fixedly installed on the left side of the fixed base 1; a slide rod 72, with an integrally formed disc at one end of the slide rod 72, the disc being slidably installed in the clearance groove; and a movable block 73, with a third mounting hole extending through the left and right sides of the movable block 73, the other end of the slide rod 72 passing through the third mounting hole, and a third thread at the other end of the slide rod 72, with a third nut screwed into the third thread.

[0052] The lifting module 8 includes a motor 81, multiple motors 81 are provided, and the motors 81 are fixedly installed on the top of the fixed base 1. A screw 82 is provided, the rotating shaft of the motor 81 is fixedly connected to the top of the screw 82, the top of the screw 82 is provided with a fourth thread, the bottom of the screw 82 is provided with a fifth thread, the pitch of the fifth thread is less than the pitch of the fourth thread, and the helixes of the fourth thread and the fifth thread are in opposite directions. A first sleeve 83 is provided, which is inserted into a first mounting hole, the top of the screw 82 is inserted into the first sleeve 83, and the inner wall of the first sleeve 83 is provided with a fourth thread. A second sleeve 84 is fixedly installed with a first limiting block 5, the bottom of the screw 82 is inserted into the second sleeve 84, and the inner wall of the second sleeve 84 is provided with a fifth thread.

[0053] The first pressure roller 2 has a first fixing plate fixedly installed at both the front and rear ends on the left side, and the second pressure roller 4 has a second fixing plate fixedly installed at both the front and rear ends on the left side.

[0054] Specific implementation process: The right end of the first pressure roller 2 is fixedly installed on the right side of the fixed base 1 with bolts. The first fixed plate at the left end of the first pressure roller 2 is moved to the gap between the first clamping block 34 and the first clamping rod 33. The first pressure roller 2 is horizontally aligned so that the center line of the first pressure roller 2 is kept horizontal. The first nut of the third round rod 371 and the second nut of the fifth round rod 373 are rotated so that the two ends of the third round rod 371 enter the interior of the third round rod 371 and the fifth round rod 373 respectively. This causes the first clamping rod 33 to rotate and move closer to each other. The first round rod of the first clamping block 34 passes through the third clearance hole of the first clamping block 34, thereby driving the first clamping block 34 closer to the first fixed plate of the first pressure roller 2. The second telescopic module 38 is also driven to drive the second clamping block 35 closer to the first fixed plate of the first pressure roller 2. Under the action of the first clamping block 34 and the second clamping block 35, the first pressure roller 2 is fixed. The second fixed blocks 71 on the left and right sides of the second pressure roller 4 move to the gap between the bearing seat 32 and the movable block 73. The first limiting block 5 is fixedly installed on the top of the second pressure roller 4, and the second limiting block 6 is fixedly installed on the first limiting block 5. On the closer side, the first limiting block 5 and the second limiting block 6 restrict the second pressure roller 4 to move only up and down, and prevent it from moving forward, backward, left, or right. The motor 81 drives the screw 82 to rotate. The screw 82 rotates once in the first sleeve 83, advancing the pitch of the fourth thread. The screw 82 also rotates once in the second sleeve 84. Because the pitch of the fifth thread is smaller than that of the fourth thread, and the helixes of the fourth and fifth threads are in opposite directions, the second sleeve 84 moves relative to the screw 82 towards the first sleeve 83. In general, relative to the motor 81, the second sleeve 84 moves away from the first sleeve 83 by the difference between the pitch of the fourth thread and the pitch of the fifth thread, thereby increasing the movement accuracy of the second pressure roller 4 and more accurately controlling the movement distance of the second pressure roller 4. When the second pressure roller 4 moves to the corresponding position, the third nut is rotated to move the movable block 73 to one side of the fixed seat 1. Under the action of the movable block 73 and the bearing seat 32, the second pressure roller 4 is fixed, thereby fixing the interval between the first pressure roller 2 and the second pressure roller 4.

[0055] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0056] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
