Description

Technical Field

[0001] This utility model relates to the field of hot press rollers, specifically a hot press roller assembly. Background Technology

[0002] Hot press rollers are key components widely used in many industrial production fields. Hot press rollers typically consist of a metal roller as the main structure, equipped with heating elements such as resistance wires, hot oil circulation channels, or steam pipes inside, which are used to heat the roller surface to the required working temperature. Their main function is to process specific materials by heating and applying pressure to achieve the expected physical or chemical changes, thereby meeting the requirements of the production process.

[0003] When the hot press roller is in operation, its heating system raises the surface temperature of the roller to the value required for a specific process. At the same time, the external pressure makes the roller come into close contact with the material being processed. When the material being processed passes through the gap between the hot press rollers, heat is rapidly transferred from the roller surface to the material, causing it to soften, melt, or undergo a chemical reaction. Meanwhile, the pressure causes the material to deform, bond, or laminate, ultimately achieving the process objectives of forming, compounding, and surface treatment of the material.

[0004] Currently, before plastic film and other processing materials enter the hot press roller equipment, the plastic film may have wrinkles or folds in the spread area. Plastic film with wrinkles or folds will seriously affect the hot press roller to process plastic film lamination, resulting in poor production quality of the laminated film. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a hot press roller assembly to solve the technical problem that existing hot press rollers have difficulty in handling plastic films with wrinkles or folds when performing composite processing on plastic films.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot press roller assembly, including an operating table, a support frame on the top of the operating table, a sorting device installed on the inner wall of the support frame, a fixing frame fixed on the top of the sorting device, a connecting frame connected to one side of the fixing frame, a connecting plate installed at the end of the connecting frame, a fixing plate at the bottom of the connecting plate, a first extrusion roller installed inside the fixing plate, a second extrusion roller installed at the bottom of the first extrusion roller, a support frame fixed on the top of the operating table, a hot press roller installed inside the support frame, and a control box on one side of the operating table.

[0007] By adopting the above technical solution, the technical problem of existing hot press rollers being unable to handle plastic films with wrinkles or folds during the lamination process is solved. The sorting device sorts and flattens the folded areas of the plastic film. Then, the plastic film moves to one side of the first and second extrusion rollers. Since a spring is installed between the connecting plate and the fixed plate, the spring presses the fixed plate downward, causing the first extrusion roller installed at the bottom of the fixed plate to press the plastic film with the cooperation of the second extrusion roller. The first extrusion roller flattens the wrinkled plastic film. Then, the extruded plastic film moves into the interior of the hot press roller, and the hot press roller processes and laminates the plastic film using the high temperature on its surface.

[0008] The present invention is further configured such that multiple sets of rollers are installed on the top of the operating table, and the top of the rollers is slightly higher than the top plane of the operating table.

[0009] By adopting the above technical solution, when the traction equipment pulls the plastic film, the roller set on the top of the operating table can reduce the contact friction between the plastic film and the operating table.

[0010] The present invention is further configured such that a lead screw is installed on the top of the connecting frame, and a handle is provided at the end of the lead screw.

[0011] By adopting the above technical solution, the operator rotates the handle, which drives the lead screw to rotate. Since the lead screw and the connecting frame are connected by threads, the rotation of the lead screw causes the connecting frame to move up and down.

[0012] The present invention is further configured such that a slider is provided at the end of the stylist, and one side of the stylist is arc-shaped.

[0013] By adopting the above technical solution, the slider at the end of the finisher moves up and down inside the support frame. The support frame limits the finisher by controlling the slider. The arc-shaped setting on one side of the finisher can reduce the damage to the plastic film caused by the edge of the finisher.

[0014] The present invention is further configured such that a limit post is fixed at the bottom of the connecting plate.

[0015] By adopting the above technical solution, the connecting plate limits the fixing plate through the limiting post to prevent the first extrusion roller from causing positional displacement when extruding the plastic film.

[0016] The present invention is further configured such that a limiting block is provided at the end of the limiting post, and the diameter of the limiting block is larger than the diameter of the limiting post.

[0017] By adopting the above technical solution, the limiting post limits the fixed plate through the limiting block. Since there is a spring between the connecting plate and the fixed plate, the setting of the limiting block enables the connecting plate and the fixed plate to maintain a certain distance.

[0018] The present invention is further configured such that a spring is fixed at the bottom of the connecting plate, and the spring is sleeved on the outer wall of the limiting post.

[0019] By adopting the above technical solution, the spring presses the fixing plate downwards, so that the first extrusion roller installed at the bottom of the fixing plate, in cooperation with the second extrusion roller, presses the wrinkled plastic film flat.

[0020] The present invention is further configured such that a rotating groove is provided on the top of the operating table, and the rotating groove is located directly below the hot press roller.

[0021] By adopting the above technical solution, since the lower roller of the hot press roller is located inside the operating table, the hot press roller exchanges a certain amount of heat with the surrounding air. The rotating groove set at the bottom of the hot press roller allows the air that has absorbed the heat of the hot press roller to circulate and exchange with the outside air.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the technical problem of existing hot press rollers being unable to handle plastic films with wrinkles or folds during the lamination process by setting up an operating table, a sorting device, a first extrusion roller, and a second extrusion roller. The sorting device smooths out the folded areas of the plastic film and then moves the plastic film to one side of the first and second extrusion rollers. Since a spring is installed between the connecting plate and the fixed plate, the spring presses the fixed plate downwards, causing the first extrusion roller installed at the bottom of the fixed plate to press the plastic film with the cooperation of the second extrusion roller. The first extrusion roller flattens the wrinkled plastic film, and then the extruded plastic film moves into the interior of the hot press roller. The hot press roller processes and laminates the plastic film using the high temperature on its surface.

[0024] 2. By setting up vent holes, rotating grooves and ventilation grooves, the present invention allows outside air to flow into the interior of the rotating groove through the ventilation grooves and vent holes, so that the interior of the rotating groove forms circulating air, thereby reducing the difference in heat dissipation between the upper and lower rollers of the hot press roller.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1

[0036] A hot press roller assembly, such as Figure 1 - Figure 5As shown, the system includes an operating table 1, a support frame 2 on top of the operating table 1, a sorting device 3 installed on the inner wall of the support frame 2, a fixing frame 201 fixed on top of the sorting device 3, a connecting frame 202 connected to one side of the fixing frame 201, a connecting plate 602 installed at the end of the connecting frame 202, a fixing plate 603 at the bottom of the connecting plate 602, a first extrusion roller 6 installed inside the fixing plate 603, a second extrusion roller 601 installed at the bottom of the first extrusion roller 6, a support frame 501 fixed on top of the operating table 1, a hot press roller 5 installed inside the support frame 501, and a control box 101 on one side of the operating table 1. This system solves the problem of existing hot press rollers in the lamination processing of plastic films. The technical problem of handling plastic films with wrinkles or folds is difficult to solve. The sorter 3 sorts and flattens the folded areas of the plastic film. Then the plastic film moves to one side of the first extrusion roller 6 and the second extrusion roller 601. Since a spring 606 is installed between the connecting plate 602 and the fixed plate 603, the spring 606 presses the fixed plate 603 downward, so that the first extrusion roller 6 installed at the bottom of the fixed plate presses the plastic film with the cooperation of the second extrusion roller 601. The first extrusion roller 6 flattens the wrinkled plastic film. Then the extruded plastic film moves into the interior of the hot press roller 5. The hot press roller 5 processes and laminates the plastic film with the high temperature on its surface.

[0037] Please see Figure 1 Multiple sets of rollers 102 are installed on the top of the operating table 1, and the top of the rollers 102 is slightly higher than the top plane of the operating table 1. When the traction device pulls the plastic film, the rollers 102 installed on the top of the operating table 1 can reduce the contact friction between the plastic film and the operating table 1.

[0038] Please see Figure 2 A lead screw 4 is installed on the top of the connecting frame 202, and a handle 401 is provided at the end of the lead screw 4. When the operator rotates the handle 401, the handle 401 drives the lead screw 4 to rotate. Since the lead screw 4 is connected to the connecting frame 202 by a thread, the rotation of the lead screw 4 causes the connecting frame 202 to move up and down.

[0039] Please see Figure 3 The end of the sorter 3 is provided with a slider 301. One side of the sorter 3 is arc-shaped. The slider 301 at the end of the sorter 3 moves up and down inside the support frame 2. The support frame 2 limits the sorter 3 through the slider 301. The arc-shaped design on one side of the sorter 3 can reduce the damage of the plastic film to the edges of the sorter 3.

[0040] Please see Figure 5 The bottom of the connecting plate 602 is fixed with a limiting post 604. The connecting plate 602 limits the fixing plate 603 through the limiting post 604 to prevent the first extrusion roller 6 from shifting position when it extrudes the plastic film.

[0041] Please see Figure 5 The end of the limiting post 604 is provided with a limiting block 605, and the diameter of the limiting block 605 is larger than the diameter of the limiting post 604. The limiting post 604 limits the fixing plate 603 through the limiting block 605. Since a spring 604 is provided between the connecting plate 602 and the fixing plate 603, the setting of the limiting block 605 enables the connecting plate 602 and the fixing plate 603 to maintain a certain distance.

[0042] Please see Figure 5 A spring 604 is fixed to the bottom of the connecting plate 602, and a spring 606 is sleeved on the outer wall of the limiting post 604. The spring 606 presses down on the fixing plate 603, so that the first extrusion roller 6 installed at the bottom of the fixing plate 603 presses the plastic film with wrinkles by cooperating with the second extrusion roller 601.

[0043] Please see Figure 4 The top of the operating table 1 is provided with a rotating groove 502, and the rotating groove 502 is located directly below the hot press roller 5. Since the lower roller of the hot press roller 5 is located inside the operating table 1, the hot press roller 5 exchanges heat with the surrounding air. The rotating groove 502 at the bottom of the hot press roller 5 allows the air that has absorbed the heat of the hot press roller 5 to circulate and exchange with the outside air.

[0044] Example 2

[0045] A hot press roller assembly, such as Figure 6 and Figure 7 As shown, the technical solution and components of this embodiment are basically the same as those of Embodiment 1. The technically similar parts will not be described again here. The difference is that the inner wall of the rotating groove 502 is provided with multiple sets of ventilation holes 503, and the ventilation holes 503 are equally spaced. The ends of the ventilation holes 503 are connected to ventilation grooves 504. The bottom of the ventilation grooves 504 is connected to the outside. Since the upper roller of the hot press roller 5 is located at the top of the operating table 1, while the lower roller of the hot press roller 5 is located inside the operating table 1, there is a difference in the heat dissipation of the upper roller and the lower roller of the hot press roller 5. This results in a difference in the heat received by the top and bottom areas of the plastic film. Outside air flows into the interior of the rotating groove 502 through the ventilation grooves 504 and the ventilation holes 503, so that the interior of the rotating groove 502 forms circulating air, thereby reducing the difference in the heat dissipation of the upper roller and the lower roller of the hot press roller 5.

[0046] The working principle of this utility model is as follows: First, the traction device guides the plastic film through the areas of the sorting device 3, the first extrusion roller 6, and the hot press roller 5 in sequence. The operator rotates the handle 401, which drives the lead screw 4 to rotate. Since the lead screw 4 is connected to the connecting frame 202 by a thread, the rotation of the lead screw 4 causes the connecting frame 202 to move up and down, adjusting the distance between the sorting device 3 and the surface of the operating table 1 to a suitable distance. The sorting device 3 sorts and flattens the areas of the plastic film that are folded. Then, the plastic film moves to one side of the first extrusion roller 6 and the second extrusion roller 601. Since a spring 606 is installed between the connecting plate 602 and the fixed plate 603, the spring 606 presses the fixed plate 603 downward, so that the first extrusion roller 6 installed at the bottom of the fixed plate 603, through cooperation with the second extrusion roller 601, presses the plastic film with wrinkles. Then, the extruded plastic film moves into the interior of the hot press roller 5, where the hot press roller 5 processes and laminates the plastic film through the high temperature on its surface.

[0047] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
