Description

Technical Field

[0001] The utility model relates to the technical field of film laminating equipment, in particular to a double-sided multi-layer film laminating device. Background Art

[0002] Acrylic sheet lamination refers to covering the surface of acrylic sheet with a protective film. This protective film is usually made of PET substrate coated with acrylic glue. Acrylic sheet lamination can provide an extra layer of protection to its surface to prevent damage or scratches caused by friction, collision or scratches during daily use, transportation or installation. This protection can ensure that the acrylic sheet maintains its original beauty and smoothness for a long time. Lamination can also enhance the weather resistance of acrylic sheet, making it better resistant to erosion by environmental factors such as ultraviolet rays, moisture, and chemicals.

[0003] Most of the current acrylic sheet laminating equipment can only laminate one side of the acrylic sheet at a time. After laminating one side, the acrylic sheet needs to be turned over for laminating on the other side, which is troublesome to operate. In addition, the existing laminating equipment needs to be manually adjusted when laminating acrylic sheets of different thicknesses, thereby reducing the laminating efficiency of the acrylic sheet. Utility Model Content

[0004] The purpose of the utility model is to provide a double-sided multi-layer laminating device to solve the problem mentioned in the above background technology that most of the current acrylic plate laminating equipment can only laminate one side of the acrylic plate at a time, and after laminating one side, the acrylic plate needs to be turned over for laminating the other side, which is troublesome to operate. In addition, when laminating acrylic plates of different thicknesses, the existing laminating equipment needs manual adjustment, which reduces the laminating efficiency of the acrylic plate.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A double-sided multi-layer laminating device comprises a laminating mechanism, one side of which is fixedly provided with a heat drying mechanism;

[0007] The coating mechanism includes a feed rack, the bottom of the feed rack is symmetrically fixedly connected to two supporting columns, the end of the feed rack is symmetrically fixedly connected to two side plates, two limit grooves are symmetrically provided on the side plates, the two limit grooves are slidably connected with sliding seats, a rotating shaft 1 is rotatably connected in the sliding seat, a coating roller is fixedly sleeved on the rotating shaft 1, a bevel gear 1 is fixedly sleeved on the end of the rotating shaft 1, a bevel gear 2 is meshingly connected to one side of the bevel gear 1, a driving column is slidably sleeved in the bevel gear 2, and the bottom end of the driving column is fixedly connected to the output end of a servo motor.

[0008] Furthermore, an L-shaped seat is rotatably sleeved on the end of the first rotating shaft, and the L-shaped seat is rotatably sleeved on the second bevel gear.

[0009] Furthermore, the sliding seat is fixedly connected with a compression spring which is fixedly connected to the inner wall of the side plate.

[0010] Furthermore, the top end of the side plate is fixedly connected to a limiting column, the outer side of the limiting column is slidably sleeved with a disassembly seat, a film rolling roller is rotatably arranged at the center position of the disassembly seat, a sloped seat is fixedly connected to the side wall of the disassembly seat, a round head rod is slidably inserted in the sloped seat, the outer side of the round head rod is slidably sleeved with a fixed seat, and the outer side of the round head rod is sleeved with a return spring fixed to the fixed seat.

[0011] Furthermore, two fixing frames are fixedly connected between the two side panels, an electric rod is fixedly connected between the two fixing frames, and a cutting plate is fixedly connected to the end of the electric rod.

[0012] Furthermore, the heat drying mechanism includes an oven, a fan is fixedly connected to the top of the oven, an air heater is arranged at a height above the output end of the fan, a connecting pipe is fixedly connected to the air heater, the end of the connecting pipe is fixedly connected to a cavity plate connected to the interior thereof, and a plurality of air outlet columns connected to the interior thereof are fixedly connected at equal distances to the bottom of the cavity plate.

[0013] Furthermore, two connecting plates are symmetrically fixedly connected to the inner wall of the oven, a plurality of conveying rollers are rotatably connected with each other at equal distances between the two connecting plates, the ends of the plurality of conveying rollers are fixedly sleeved with double-groove pulleys, one end of the conveying roller at the end is fixedly connected with the output end of the driving motor, and a synchronous belt is sleeved between two adjacent double-groove pulleys.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. One end of the film on the film roll will be attached to the laminating roller. When the acrylic sheet is fed between the two laminating rollers, the output end of the servo motor will drive the driving column to rotate, and the driving column can drive the two bevel gears 2 to rotate. The two bevel gears 2 in opposite directions can drive the bevel gear 1 on one side to rotate, thereby driving the two rotating shafts 1 and the laminating rollers to rotate in opposite directions at the same time. As a result, the two laminating rollers can press the film on the top and bottom surfaces of the acrylic sheet while rubbing the acrylic sheet forward, so that the double-sided automatic laminating operation of the acrylic sheet can be completed, thereby improving the laminating efficiency of the acrylic sheet. The L-shaped seat can always keep meshing between bevel gear one and bevel gear two, so that when laminating acrylic plates of different thicknesses, the extrusion spring will squeeze the two laminating rollers and keep them in contact with the two sides of the acrylic plates, and the sliding seat will slide in the limit groove when the laminating rollers are raised and lowered, so that the driving column will still drive the two laminating rollers to rotate and laminate. In this way, the device does not need to be manually adjusted when laminating acrylic plates of different thicknesses on both sides, thereby saving time and making the device more practical. Under the extrusion of the extrusion spring, the laminating rollers remain in close contact with the plate surface during laminating, thereby reducing the generation of bubbles and ensuring the production quality of the product.

[0016] 2. When the film on the film roll is used up, the round-headed rod can be pulled out from the inclined plane seat, so that the inclined plane seat loses its limit position, and then the disassembly seat slides out from the limit column, and then the film roll can be replaced to replenish the film. By pushing the disassembly seat and the limit column to re-engage and slide, the inclined surface of the inclined plane seat and the round-headed rod come into contact, and then the reset spring pops out and the inclined plane seat is reinserted into the limit position, thereby speeding up the film roll replacement speed.

[0017] 3. Through the driving motor and multiple double-groove pulleys and synchronous belts, multiple conveyor rollers can be driven to rotate at the same time. When the acrylic plate is coated, two electric rods are used to drive the cutting plate to move vertically relative to each other, so that the cutting plate can cut the film on the acrylic plate. After that, the plate body is transported in the oven through the conveyor rollers, and the outside air is introduced into the cavity plate through the fan. The air will be heated into hot air when passing through the air heater, so that hot air can be sprayed to the plate surface through multiple air outlet columns, so that the coating adhesive layer is softened, so that it can better fit with the surface of the acrylic plate, which can increase the adhesion between the coating and the acrylic plate, and ensure that the coating is more firmly attached to the acrylic plate, not easy to fall off or shift. In the process of coating, bubbles or wrinkles are sometimes inevitable. The heat baking process expands the coating material by heating, which helps to squeeze out the bubbles and flatten the wrinkles, which can further improve the appearance quality of the acrylic plate after coating.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 6 In an embodiment of the utility model, a double-sided multi-layer laminating device includes a laminating mechanism 100, and a heat drying mechanism 200 is fixedly arranged on one side of the laminating mechanism 100;

[0027] The coating mechanism 100 includes a feed rack 101, the bottom of which is symmetrically fixedly connected with two support columns 102, the end of which is symmetrically fixedly connected with two side panels 103, two limit grooves 104 symmetrically provided on the side panels 103, the two limit grooves 104 are slidably connected with sliding seats 105, the sliding seats 105 are rotatably connected with a rotating shaft 106, a coating roller 107 is fixedly sleeved on the rotating shaft 106, a bevel gear 109 is fixedly sleeved on the end of the rotating shaft 106, a bevel gear 110 is meshedly connected to one side of the bevel gear 109, a driving column 112 is slidably sleeved in the bevel gear 110, and the bottom end of the driving column 112 is fixedly connected with the output end of a servo motor 113; an L-shaped seat 111 is rotatably sleeved on the end of the rotating shaft 106, and the L-shaped seat 111 is rotatably sleeved with the bevel gear 110.

[0028] Specifically, one end of the adhesive film on the film-winding roller 116 will be attached to the coating roller 107. When the acrylic sheet is fed between the two coating rollers 107, the output end of the servo motor 113 will drive the driving column 112 to rotate, and the driving column 112 can drive the two bevel gears 110 to rotate. The two bevel gears 110 in opposite directions can drive the bevel gear 1 109 on one side to rotate, thereby driving the two rotating shafts 106 and the coating rollers 107 to rotate in opposite directions at the same time, so that the two coating rollers 107 can press the adhesive film on the top and bottom surfaces of the acrylic sheet while rubbing the acrylic sheet forward, thereby completing the double-sided automatic coating operation of the acrylic sheet, thereby improving the coating efficiency of the acrylic sheet. Since the bevel gear 109 and the bevel gear 2 110 can always keep meshing through the L-shaped seat 111, when coating acrylic plates of different thicknesses, the extrusion spring 108 will squeeze the two coating rollers 107 and keep them in contact with the two sides of the acrylic plate, and the sliding seat 105 will slide in the limit groove 104 when the coating rollers 107 are raised and lowered, so that the driving column 112 can still drive the two coating rollers 107 to rotate and coat. In this way, the device does not need to be manually adjusted when coating acrylic plates of different thicknesses on both sides, thereby saving time and making the device more practical. In addition, under the extrusion of the extrusion spring 108, the coating rollers 107 remain in close contact with the plate surface during coating, thereby reducing the generation of bubbles, thereby ensuring the production quality of the product.

[0029] Embodiment 1

[0030] like Figure 5As shown, in the present embodiment, the top end of the side plate 103 is fixedly connected to a limiting column 114, the outer portion of the limiting column 114 is slidably sleeved with a disassembly seat 115, a film rolling roller 116 is rotatably provided at the center position of the disassembly seat 115, a sloped seat 117 is fixedly connected to the side wall of the disassembly seat 115, a round head rod 118 is slidably inserted in the sloped seat 117, the outer portion of the round head rod 118 is slidably sleeved with a fixed seat 119, and the outer portion of the round head rod 118 is sleeved with a return spring 120 fixed to the fixed seat 119.

[0031] In this embodiment, when the film on the film roller 116 is used up, the round head rod 118 can be pulled out from the inclined plane seat 117, so that the inclined plane seat 117 loses its limit, and then the disassembly seat 115 can be slid out from the limiting column 114, and then the film roller 116 can be replaced to replenish the film. By pushing the disassembly seat 115 and the limiting column 114 to re-engage and slide, the inclined surface of the inclined plane seat 117 and the round head rod 118 collide with each other, and then the reset spring 120 pops out and the inclined plane seat 117 is reinserted into the limit, thereby speeding up the replacement speed of the film roller 116.

[0032] Embodiment 2

[0033] like Figure 6 As shown, in this embodiment, the hot drying mechanism 200 includes an oven 201, a fan 202 is fixedly connected to the top of the oven 201, an air heater 203 is arranged at a height above the output end of the fan 202, a connecting pipe 204 is fixedly connected to the air heater 203, a cavity plate 205 connected to the inside of the connecting pipe 204 is fixedly connected to the end of the connecting pipe 204, and a plurality of air outlet columns 206 connected to the inside of the cavity plate 205 are fixedly connected to the bottom of the cavity plate 205 at equal distances; two connecting plates 207 are symmetrically fixedly connected to the inner wall of the oven 201, and a connecting plate 207 is rotatably connected to the two connecting plates 207 at equal distances. There are multiple conveying rollers 209, and the ends of the multiple conveying rollers 209 are fixedly sleeved with double-groove pulleys 210. One end of the conveying roller 209 located at the end is fixedly connected to the output end of the driving motor 208, and a synchronous belt 211 is sleeved between two adjacent double-groove pulleys 210; the sliding seat 105 is fixedly connected with an extrusion spring 108 fixedly connected to the inner wall of the side plate 103; two fixing frames 121 are fixedly connected between the two side plates 103, and an electric rod 122 is fixedly connected between the two fixing frames 121, and a cutting plate 123 is fixedly connected to the end of the electric rod 122.

[0034] In a specific implementation, the driving motor 208, the multiple double-groove pulleys 210 and the synchronous belt 211 can simultaneously drive the multiple conveying rollers 209 to rotate, so that when the coating of the acrylic plate is completed, the two electric rods 122 are used to drive the cutting plate 123 to move relatively vertically, so that the cutting plate 123 can cut the film on the acrylic plate, and then the plate body is conveyed in the oven 201 by the conveying rollers 209, and the outside air is introduced into the cavity plate 205 by the fan 202. When the air passes through the air heater 203, It is heated into hot air, so that hot air can be sprayed to the board surface through multiple air outlet columns 206, so that the coating adhesive layer is softened, so that it can better fit with the surface of the acrylic board. This can increase the adhesion between the coating and the acrylic board, ensure that the coating is more firmly attached to the acrylic board and is not easy to fall off or shift. In the process of laminating, bubbles or wrinkles are sometimes unavoidable. The heat baking process expands the coating material by heating, which helps to squeeze out the bubbles and flatten the wrinkles. This can further improve the appearance quality of the acrylic board after lamination.
