AI Technical Summary
Existing cold laminating equipment generally adopts a split design. The cylinder pressure adjustment of the laminator can only control the tightness of the lamination, but has no ability to adjust the tension of the film conveying. This causes the film to loosen and produce air bubbles when the suspension section swings, and the film to stretch and narrow when the tension increases suddenly.
Design a cold laminating machine including a support, an unwinding assembly, a guiding assembly, a tensioning assembly, and a pressing assembly. The tension of the film can be adjusted by connecting the guiding assembly and the tensioning assembly. The pressing gap can be adjusted by using the lifting frame and the pressure roller to accommodate strip steel and coated film of different thicknesses.
It enables flexible adjustment of film tension, avoiding problems such as film slack or stretching and narrowing, and ensuring a tight bonding effect of the coated film.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cold laminating machines, and specifically relates to a cold laminating machine applied to a continuous production line for color coating of steel strip. Background Technology
[0002] As an important intermediate product of the steel industry, strip steel refers to continuous strip steel with a thickness between 0.1-3mm and a width typically between 500-2000mm. Its production process includes multiple steps such as hot rolling, pickling, and cold rolling. After degreasing and chemical conversion treatment, the cold-rolled strip steel substrate undergoes surface coating on a continuous production line to form a color-coated steel sheet that combines corrosion resistance and decorative functions.
[0003] Current cold laminating equipment generally adopts a split design, consisting of an independently operating film feeding machine and a film pressing machine. The pressure adjustment of the cylinder in the film pressing machine can only control the tightness of the pressing, and has no ability to adjust the tension of the film being transported. When the suspension section swings, causing the film to loosen, air bubbles appear in the pressing zone; when the tension increases suddenly, it causes the film to stretch and narrow. Utility Model Content
[0004] Current cold laminating equipment generally adopts a split design, consisting of an independently operating film feeding machine and a film pressing machine. The pressure adjustment of the pressing machine's cylinder can only control the tightness of the pressing, but has no ability to adjust the tension of the film conveying. When the suspension section swings, causing the film to loosen, air bubbles appear in the pressing zone; when the tension increases suddenly, it causes the film to stretch and narrow. This utility model proposes a cold laminating machine for continuous production lines of color coating on steel strips to overcome the above-mentioned technical problems existing in related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a cold laminating machine applied to a continuous production line for color coating of steel strips. It includes a support frame, and an unwinding assembly, a guiding assembly, a tensioning assembly, and a pressing assembly are arranged on the top of the support frame. The unwinding assembly and the tensioning assembly are respectively located on both sides of the support frame. The guiding assembly is located between the unwinding assembly and the tensioning assembly. The tensioning assembly is installed on the outer surface of the pressing assembly.
[0007] Furthermore, the unwinding assembly includes a support, which is fixedly connected to the outer surface of the bracket. A winding roller is rotatably mounted on the outer surface of the support. A mounting base is fixedly connected to the side of the bracket. A motor is fixedly mounted on the top of the mounting base. The output shaft of the motor is connected to the winding roller in a transmission connection.
[0008] Furthermore, the guiding assembly includes a horizontal column, which is fixedly connected to the outer surface of the bracket. A first bearing and a second bearing are fixedly mounted on the outer surface of the horizontal column. A guide roller is rotatably connected to the outer surface of the first bearing, and a tension measuring roller is rotatably connected to the outer surface of the second bearing.
[0009] Furthermore, the tensioning assembly includes a fixed seat, which is fixedly installed on the outer surface of the pressure film assembly. A screw is rotatably connected inside the fixed seat, and a sliding seat is threadedly connected to the outer surface of the screw. The sliding seat is slidably connected to the fixed seat. There are two sets of the fixed seat, the screw, and the sliding seat, and a tensioning roller is rotatably connected between the two sets of sliding seats.
[0010] Furthermore, the pressing assembly includes a first connecting seat, which is fixedly connected to the outer surface of the bracket. An electric push rod is fixedly installed on the outer surface of the first connecting seat. A second connecting seat is fixedly connected to the movable end of the electric push rod. A lifting frame is fixedly installed at the bottom of the second connecting seat. A slider is fixedly connected to the outer surface of the lifting frame. A slide rail is slidably connected to the outer surface of the slider. The slide rail is fixedly connected to the outer surface of the bracket. A first pressure roller is rotatably installed at the bottom of the lifting frame. A second pressure roller is rotatably installed on the outer surface of the bracket.
[0011] Furthermore, an I-beam is fixedly connected to the top of the support, and a gantry crane is slidably connected to the outer surface of the I-beam.
[0012] Furthermore, a handwheel is fixedly connected to the outer surface of the screw.
[0013] This utility model has the following beneficial effects:
[0014] 1. This utility model connects the guiding component and the tensioning component. The guiding component guides the steel strip and the coating film to the outer surface of the tensioning component. Both the steel strip and the coating film pass around the tensioning component clockwise. When the tensioning component moves away from the guiding component, the tensioning component can tighten the steel strip and the coating film. When the tensioning component moves close to the guiding component, the steel strip and the coating film are in a relaxed state, which is convenient for adjustment according to the actual situation.
[0015] 2. This utility model connects the lifting frame and the first pressure roller. When the electric push rod is activated, the lifting frame moves up and down along the slide rail. The lifting frame can drive the first pressure roller to move synchronously, thereby changing the gap between the first pressure roller and the second pressure roller. When the gap increases, it is easier for the strip steel and the coating film to pass between the first pressure roller and the second pressure roller. When the gap decreases, the first pressure roller and the second pressure roller cooperate to press the coating film onto the surface of the strip steel. The gap between the first pressure roller and the second pressure roller can also be flexibly adjusted according to the thickness of the strip steel and the coating film.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0029] Please see Figures 1-7 As shown, this utility model is a cold laminating machine applied to a continuous production line for color coating of steel strip, including a support 1. The top of the support 1 is provided with an unwinding assembly 2, a guiding assembly 3, a tensioning assembly 4 and a pressing assembly 5. The unwinding assembly 2 and the tensioning assembly 4 are respectively located on both sides of the support 1. The guiding assembly 3 is located between the unwinding assembly 2 and the tensioning assembly 4. The tensioning assembly 4 is installed on the outer surface of the pressing assembly 5.
[0030] After the unwinding assembly 2 at the top of the support 1 is activated, the unwinding assembly 2 releases the strip steel and the coating film and passes through the guide assembly 3. Under the action of the guide assembly 3, the strip steel and the coating film pass over the tensioning assembly 4. After passing through the tensioning assembly 4, the strip steel and the coating film pass between the pressing assembly 5, and the pressing assembly 5 presses the strip steel and the coating film together.
[0031] This utility model connects the guide component 3 and the tensioning component 4. The guide component 3 guides the steel strip and the coating film to the outer surface of the tensioning component 4. Both the steel strip and the coating film pass around the tensioning component 4 clockwise. When the tensioning component 4 is away from the guide component 3, the tensioning component 4 can tighten the steel strip and the coating film. When the tensioning component 4 is close to the guide component 3, the steel strip and the coating film are in a relaxed state, which is convenient for adjustment according to the actual situation.
[0032] In one embodiment, the unwinding assembly 2 includes a support 201, which is fixedly connected to the outer surface of the bracket 1. A winding roller 202 is rotatably mounted on the outer surface of the support 201. A mounting base 203 is fixedly connected to the side of the bracket 1. A motor 204 is fixedly mounted on the top of the mounting base 203. The output shaft of the motor 204 is connected to the winding roller 202 in a transmission connection.
[0033] After the roller 202 is mounted on the outer surface of the support 201, the motor 204 is started. The output shaft of the motor 204 drives the roller 202 to rotate, so that the roller 202 rotates. There are two sets of rollers 202, namely strip steel and coating film. After the two sets of rollers 202 rotate, the strip steel and coating film can be released.
[0034] In one embodiment, the guide component 3 includes a horizontal column 301, which is fixedly connected to the outer surface of the bracket 1. A first bearing 302 and a second bearing 303 are fixedly installed on the outer surface of the horizontal column 301. A guide roller 304 is rotatably connected to the outer surface of the first bearing 302, and a tension measuring roller 305 is rotatably connected to the outer surface of the second bearing 303.
[0035] The strip steel and coating film released from the winding roller 202 pass over the guide roller 304 and then wind around to the underside of the tension measuring roller 305. The guide roller 304 and the tension measuring roller 305 can rotate between the first bearing 302 and the second bearing 303, respectively. The tension measuring roller 305 is connected to a sensor for measuring tension.
[0036] In one embodiment, the tensioning assembly 4 includes a fixed seat 401, which is fixedly mounted on the outer surface of the pressure film assembly 5. A screw 402 is rotatably connected inside the fixed seat 401, and a sliding seat 403 is threadedly connected to the outer surface of the screw 402. The sliding seat 403 is slidably connected to the fixed seat 401. There are two sets of the fixed seat 401, the screw 402, and the sliding seat 403, and a tensioning roller 404 is rotatably connected between the two sets of sliding seats 403.
[0037] The strip steel and coating film, which extend from below the tension measuring roller 305, are wound clockwise onto the outer surface of the tensioning roller 404. When the screw 402 is rotated, the rotational tendency of the sliding seat 403 on the outer surface of the screw 402 is blocked by the fixed seat 401. At this time, the screw 402 can drive the sliding seat 403 to move the tensioning roller 404. When the tensioning roller 404 moves away from the tension measuring roller 305, the strip steel and coating film are in a taut state. When the tensioning roller 404 moves closer to the tension measuring roller 305, the strip steel and coating film are in a relaxed state. The adjustment can be made according to the data detected by the built-in sensor of the tension measuring roller 305.
[0038] In one embodiment, the film pressing assembly 5 includes a first connecting seat 501, which is fixedly connected to the outer surface of the support 1. An electric push rod 502 is fixedly installed on the outer surface of the first connecting seat 501. A second connecting seat 503 is fixedly connected to the movable end of the electric push rod 502. A lifting frame 504 is fixedly installed at the bottom of the second connecting seat 503. A slider 505 is fixedly connected to the outer surface of the lifting frame 504. A slide rail 506 is slidably connected to the outer surface of the slider 505. The slide rail 506 is fixedly connected to the outer surface of the support 1. A first pressure roller 507 is rotatably installed at the bottom of the lifting frame 504. A second pressure roller 508 is rotatably installed on the outer surface of the support 1.
[0039] The strip steel and coating film pass clockwise around the outer surface of the tension roller 404 and then pass between the first pressure roller 507 and the second pressure roller 508. The electric push rod 502 is activated, and the movable end of the electric push rod 502 drives the lifting frame 504 and the slider 505 to slide along the slide rail 506. The lifting frame 504 drives the first pressure roller 507 to move. When the first pressure roller 507 approaches the second pressure roller 508, the coating film can be pressed onto the surface of the strip steel.
[0040] In one embodiment, for the aforementioned support 1, an I-beam 6 is fixedly connected to the top of the support 1, and a gantry crane 7 is slidably connected to the outer surface of the I-beam 6.
[0041] After the gantry crane 7 is started, the gantry crane 7 moves along the I-beam 6, and the strip steel and the coated film roll 202 can be lifted and placed on the top of the support 201 by the gantry crane 7.
[0042] In one embodiment, a handwheel 8 is fixedly connected to the outer surface of the screw 402.
[0043] One end of the screw 402 extends to the outside of the fixed base 401, and this end is fixedly connected to the handwheel 8. The handwheel 8 is configured to provide a force point for rotating the screw 402, making it easier to push the screw 402 to rotate.
[0044] Through the above technical solution: 1. By connecting the guide component 3 and the tensioning component 4, the guide component 3 guides the strip steel and coating film to the outer surface of the tensioning component 4. Both the strip steel and the coating film pass clockwise around the tensioning component 4. When the tensioning component 4 is away from the guide component 3, the tensioning component 4 can tighten the steel strip and the coating film. When the tensioning component 4 is close to the guide component 3, the steel strip and the coating film are in a relaxed state, which is convenient for adjustment according to the actual situation; 2. By connecting the lifting frame 504 and the first pressure roller 507, the electric push rod 502 is activated to drive the lifting frame 504. 04. Moving up and down along the slide rail 506, the lifting frame 504 can drive the first pressure roller 507 to move synchronously, thereby changing the gap between the first pressure roller 507 and the second pressure roller 508. When the gap increases, it is easier for the strip steel and the coating film to pass between the first pressure roller 507 and the second pressure roller 508. When the gap decreases, the first pressure roller 507 and the second pressure roller 508 cooperate to press the coating film onto the surface of the strip steel. The gap between the first pressure roller 507 and the second pressure roller 508 can also be flexibly adjusted according to the thickness of the strip steel and the coating film.
