Description

Technical Field

[0001] This utility model relates to the field of pressure roller technology, and specifically to a variable pressure roller. Background Technology

[0002] Decorative film is a new type of decorative material made from high-molecular polymers (such as PVC) as raw materials, with the addition of various additives, through calendering and lamination. It has good UV resistance and anti-aging properties, which can extend the service life of products. It is also environmentally friendly, inexpensive, easy to install, and can save on decoration costs.

[0003] Publication number CN212763718U discloses a film pressing roller device. Its rotating transmission rod drives a screw to rotate, causing a screw sleeve to disengage and move downwards under the rotation of the screw. This causes a connecting plate to move a cutter downwards, exposing the cutter in a cutting groove. A plastic film is then placed in the pressing channel between the upper and lower film pressing rollers. A drive motor rotates both rollers. Each rotation of the upper roller cuts a plastic film sheet with a circumference equal to that of the upper roller. However, this device can only process decorative films of a single specification and cannot adjust the spacing between the rollers to meet different needs. Therefore, processing decorative films of different thicknesses requires the use of other types of equipment, which has certain limitations. To address this, we propose a variable film pressing roller. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a variable pressure roller.

[0005] The technical solution adopted by this utility model to solve its technical problem is a variable pressure roller, including a fixed base. A hydraulic lifting mechanism is installed inside one side of the fixed base. A connecting module is installed at the top of the hydraulic lifting mechanism. A first transmission rod is fixedly connected to the side wall of the connecting module. A movable pressure roller is rotatably connected to the end of the first transmission rod away from the connecting module through a coupling. The end of the movable pressure roller away from the first transmission rod is rotatably connected to the side wall of a second transmission rod. The second transmission rod is fixedly connected to the side wall of a limiting module. The limiting module is slidably connected to the outer periphery of a limiting slide rod.

[0006] The top surface of the fixed base is integrally constructed with an extension bracket. An external water inlet is connected to the side wall of the extension bracket. An internal multi-port connecting pipe connected to the external water inlet is installed inside the extension bracket. A transfer pipe is connected to the water outlet of the internal multi-port connecting pipe. The end of the transfer pipe away from the internal multi-port connecting pipe is connected to the water inlet of the pressurized atomizer. The water inlet of the pressurized atomizer is installed on the side wall of the pressurized sprayer. A spray nozzle for cooling is installed inside the pressurized sprayer.

[0007] By adopting the above technical solution, when it is necessary to adjust the distance between the two pressing rollers, the connecting module connected to the first transmission rod on one side of the movable pressing roller moves up and down with the operation of the hydraulic lift, while the limiting module connected to the second transmission rod on the other side moves up and down in coordination with the extension and retraction of the hydraulic lift under the limitation of the limiting slide rod, thereby adjusting the movable pressing roller to a suitable position to cooperate with the fixed pressing roller to perform calendering processing on the decorative film;

[0008] After the decorative film is calendered, it needs to be cooled down in time. When it passes through the through groove of the extension bracket, the water supplied through the external water inlet passes through the internal multi-connection pipe and the transfer pipe connected at both ends, and enters the interior of the pressurized sprayer through the water inlet of the sprayer for pressurization and atomization. Then it is sprayed from the spray nozzle onto the decorative film to cool it down, which also facilitates subsequent cleaning operations.

[0009] Specifically, both ends of the limiting slide rod are assembled inside the fixed base via fixed mounting seats.

[0010] By adopting the above technical solution, the limiting slide bar is fixed by a fixed mounting base, thereby cooperating with the operation of the hydraulic lift to raise or lower the movable pressure roller.

[0011] Specifically, the end of the internal multi-port connecting pipe away from the water inlet of the sprayer is equipped with a second sprayer through the same connecting structure, and the adapter pipe, spray nozzle and the second sprayer are all installed inside the extension bracket through a pressurized sprayer.

[0012] By adopting the above technical solution, when the decorative film is calendered and moved to the opening of the spray nozzle corresponding to the extension bracket, the two sides of the calendered decorative film are sprayed and cooled by two pressurized sprayers set opposite each other at the upper and lower ends.

[0013] Specifically, the extension bracket has a discharge port located in the center of the side away from the fixed base.

[0014] By adopting the above technical solution, after calendering and spray cooling treatment, the decorative film can be discharged from the outlet and then proceed to the next cleaning operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When it is necessary to adjust the distance between the two pressing rollers, the movable pressing roller is raised and lowered by the connecting module connected to the first transmission rod on one side, and the limiting module connected to the second transmission rod on the other side moves up and down in coordination with the extension and retraction of the hydraulic lift under the limitation of the limiting slide rod, thereby adjusting the movable pressing roller to a suitable position to cooperate with the fixed pressing roller to perform calendering processing on the decorative film;

[0017] After the decorative film is calendered, it needs to be cooled down in time. When it passes through the through groove of the extension bracket, the water supplied through the external water inlet passes through the internal multi-connection pipe and the transfer pipe connected at both ends, and enters the interior of the pressurized sprayer through the water inlet of the sprayer for pressurization and atomization. Then it is sprayed from the spray nozzle onto the decorative film to cool it down, which also facilitates subsequent cleaning operations. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a variable pressure roller, including a fixed base 1, a hydraulic lift 2 is installed inside one side of the fixed base 1, a connecting module 3 is installed at the top of the hydraulic lift 2, a first transmission rod 4 is fixedly connected to the side wall of the connecting module 3, a movable pressure roller 5 is rotatably connected to the end of the first transmission rod 4 away from the connecting module 3 through a coupling, the end of the movable pressure roller 5 away from the first transmission rod 4 is rotatably connected to the side wall of the second transmission rod 6, the second transmission rod 6 is fixedly connected to the side wall of the limiting module 7, and the limiting module 7 is slidably connected to the outer periphery of the limiting slide rod 8;

[0025] The top surface of the fixed base 1 has an integrally constructed extension bracket 10. The side wall of the extension bracket 10 is connected to an external water inlet 11. The extension bracket 10 is equipped with an internal multi-port connecting pipe 12 that communicates with the external water inlet 11. The water outlet of the internal multi-port connecting pipe 12 is connected to a transfer pipe 13. The end of the transfer pipe 13 away from the internal multi-port connecting pipe 12 is connected to the water inlet of the pressurized atomizer. The water inlet of the pressurized atomizer is mounted on the side wall of the pressurized sprayer 15. The interior of the pressurized sprayer 15 is equipped with a spray nozzle 16 for cooling.

[0026] In use, when it is necessary to adjust the distance between the two pressing rollers, the movable pressing roller 5 moves up and down with the hydraulic lift 2 via the connecting module 3 connected to the first transmission rod 4 on one side, and moves up and down with the extension and retraction of the hydraulic lift 2 via the limiting module 7 connected to the second transmission rod 6 on the other side under the restriction of the limiting slide rod 8, thereby adjusting the movable pressing roller 5 to a suitable position to cooperate with the fixed pressing roller to perform calendering processing on the decorative film;

[0027] After the decorative film is calendered, it needs to be cooled down in time. When it passes through the through groove of the extension bracket 10, the water supplied through the external water inlet 11 passes through the internal multi-connection pipe 12 and the adapter pipe 13 connected at both ends, and enters the interior of the pressurized sprayer 15 through the sprayer water inlet 14 for pressurization and atomization. Then it is sprayed from the spray nozzle 16 onto the decorative film to cool it down, which also facilitates subsequent cleaning operations.

[0028] As shown in the figure, the two ends of the limiting slide bar 8 are assembled inside the fixed base 1 through the fixed mounting seat 9.

[0029] In use, the limiting slide bar 8 is fixed by the fixed mounting base 9, thereby cooperating with the hydraulic lift 2 to raise or lower the movable pressure roller 5.

[0030] As shown in the figure, the end of the internal multi-connector pipe 12 away from the water inlet 14 of the sprayer is equipped with a second sprayer 17 through the same connecting structure, and the adapter pipe 13, the spray nozzle 16 and the second sprayer 17 are all installed inside the extension bracket 10 through the pressurized sprayer 15.

[0031] When in use, after the decorative film is calendered, it moves to the opening of the spray nozzle 16 corresponding to the extension bracket 10, and the two opposing pressurized sprayers 15 at the upper and lower ends spray the two sides of the calendered decorative film to cool it down.

[0032] As shown in the figure, the extension bracket 10 has a discharge port 18 in the center on the side away from the fixed base 1.

[0033] When in use, after calendering and spray cooling, the decorative film is discharged from the discharge port 18 and the next cleaning operation can be carried out.

[0034] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the distance between the two pressing rollers, one side of the movable pressing roller 5 is raised and lowered by the connecting module 3 connected to the first transmission rod 4 along with the operation of the hydraulic lift 2. The other side is raised and lowered by the limiting module 7 connected to the second transmission rod 6 under the restriction of the limiting slide rod 8, in conjunction with the extension and retraction of the hydraulic lift 2. This adjusts the movable pressing roller 5 to a suitable position. The fixed pressing roller driven by the motor rotates in conjunction with the adjustable movable pressing roller 5 at the bottom to perform calendering processing on the decorative film. After the decorative film is calendered, it needs to be lowered in time. When the decorative film passes through the through groove of the extension bracket 10, the water supplied through the external water inlet 11 passes through the internal multi-connection pipe 12 and the adapter pipe 13 connected at both ends, and enters the interior of the pressurized sprayer 15 through the sprayer water inlet 14 for pressurized atomization. When the decorative film moves to the opening of the spray nozzle 16 corresponding to the extension bracket 10 after calendering, the two pressurized sprayers 15 arranged opposite each other at the upper and lower ends spray and cool both sides of the calendered decorative film. After calendering and spray cooling treatment, the decorative film is discharged from the discharge port 18 and can proceed to the next cleaning operation.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
