Description

Technical Field

[0001] This utility model relates to the field of panel furniture coating technology, and in particular to a high-efficiency panel furniture forward and reverse pressing coating machine pressing structure. Background Technology

[0002] In the manufacturing process of panel furniture, a laminating machine is required to apply a film to the panels used in the furniture.

[0003] However, existing laminating machines for panel furniture have shortcomings in their use. They cannot simultaneously laminate both sides of the board. After laminating one side, the board needs to be flipped over before laminating the other side, resulting in low laminating efficiency. Furthermore, it is inconvenient to clean dust and impurities from the board surface before laminating, which can negatively impact the laminating effect. Additionally, it is difficult to adjust the pressure according to the laminating requirements, reducing the versatility of the device. Therefore, we propose a high-efficiency laminating structure for a double-sided laminating machine for panel furniture to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings and propose a high-efficiency panel furniture front and back pressing and laminating machine pressing structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency panel furniture front and back laminating machine laminating structure includes a frame. Four conveying rollers, two hot pressing rollers, two film rollers, and two hollow cylinders are rotatably connected to the inner walls of the front and rear sides of the frame. Panels for panel furniture processing are movably placed on the four conveying rollers. A film for laminating is wound around the film rollers, and the film is wound around the outside of the corresponding hot pressing rollers. A cover is fixedly connected to the front side of the frame. A cleaning mechanism is provided between the cover and the two hollow cylinders. Six laminating rollers are rotatably arranged inside the frame. A pressure-adjustable laminating mechanism is provided between the frame and the six laminating rollers.

[0007] In a preferred embodiment of this utility model, the cleaning mechanism includes a drive motor fixedly connected to one side of the cover and a gear fixedly sleeved on the outside of the hollow cylinder. The two gears mesh with each other. A worm gear is fixedly connected to the output shaft of the drive motor. A fan blade is fixedly connected to the outside of the worm gear. A worm wheel is fixedly sleeved on the outside of the front hollow cylinder. The worm gear meshes with the worm wheel. Several fine brushes are fixedly connected to the outside of the hollow cylinder. Multiple dust suction holes are opened on the outside of the hollow cylinder.

[0008] In a preferred embodiment of this invention, the fine brush and the dust suction hole are arranged in a crisscross pattern.

[0009] In a preferred embodiment of this invention, the cover is connected to the front ends of the two hollow cylinders.

[0010] As a preferred embodiment of this utility model, an air outlet is fixedly connected to one side of the cover, and a dust collection bag is fixedly connected to the air outlet.

[0011] As a preferred embodiment of this utility model, the pressure-adjustable film pressing mechanism includes two cylinders, which are respectively fixedly connected to the top inner wall and the bottom inner wall of the frame. A servo motor is fixedly connected to one side of each cylinder, and a driving bevel gear is fixedly connected to the output shaft of the servo motor. A lifting screw is rotatably connected to the inner wall of each cylinder on the side away from each other. A driven bevel gear is fixedly sleeved on the outer side of the lifting screw, and the driving bevel gear meshes with the driven bevel gear. A lifting column is threaded on the outer side of the lifting screw.

[0012] As a preferred embodiment of this utility model, a pressure sensor is fixedly connected to the bottom end of the lifting column, a movable plate is fixedly sleeved on the outside of the pressure sensor, two mounting plates are fixedly connected to the inside of the movable plate, and six pressure rollers are rotatably connected between the corresponding two mounting plates.

[0013] As a preferred embodiment of this utility model, four connecting plates are fixedly connected to the inner side of the movable plate, and two mounting plates are respectively fixedly connected to the bottom of the corresponding connecting plates.

[0014] As a preferred embodiment of this utility model, limit grooves are provided on both inner walls of the cylinder, and limit blocks are slidably sleeved in the limit grooves, with the two limit blocks respectively fixedly connected to both sides of the lifting column.

[0015] As a preferred embodiment of this utility model, two telescopic rods are fixedly connected to the top inner wall and the bottom inner wall of the frame, and the ends of the four telescopic rods that are close to each other are respectively fixedly connected to the corresponding movable plates.

[0016] In this utility model, the high-efficiency panel furniture front and back laminating machine has a laminating structure. Four conveying rollers transport the panels used for processing the panel furniture to the right. Before lamination, a drive motor rotates a worm gear, which in turn drives a worm wheel and a hollow cylinder. Through the meshing of two gears, the two hollow cylinders rotate in opposite directions. These two hollow cylinders drive the rotation of multiple fine brushes, simultaneously cleaning dust and impurities adhering to both sides of the panel, preventing them from affecting the subsequent lamination effect. Two film rollers provide film to the hot pressing rollers. The two hot pressing rollers heat-press the film onto both sides of the panel, achieving double-sided lamination and improving the efficiency of panel lamination. After heat pressing, the panel continues to be transported to the area of ​​the laminating rollers to the right.

[0017] In this utility model, the high-efficiency panel furniture forward and reverse laminating machine pressing structure, according to the pressing needs, starts a servo motor, which drives the rotation of the active bevel gear, which in turn drives the rotation of the driven bevel gear and the lifting screw. Under the limit of the limit block, the lifting screw drives the lifting column and the pressure sensor to move closer to the board. The pressure sensor can detect the pressure of the pressing film. When the requirement is met, the pressure sensor sends a signal to the controller, which then shuts off the servo motor, thereby adjusting the pressure of the pressing film. This not only improves the pressing effect of the pressing roller on the film, but also improves the versatility of the device.

[0018] This utility model has a reasonable structural design. Before lamination, it can clean and remove dust and impurities attached to both sides of the board, ensuring the cleanliness of both sides and improving the lamination effect. Furthermore, by setting two hot press rollers and multiple lamination rollers, double-sided lamination of the board can be performed, improving the efficiency of lamination. The lamination pressure can also be adjusted according to the lamination requirements, ensuring not only the lamination effect but also improving the versatility of the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-4 A high-efficiency panel furniture front and back laminating machine laminating structure includes a frame 1. Four conveying rollers 2, two hot pressing rollers 6, two film rollers 3, and two hollow cylinders 51 are rotatably connected to the inner walls of the front and rear sides of the frame 1. Panels for panel furniture processing are movably placed on the four conveying rollers 2. Films 4 for laminating are wound around the film rollers 3 and are wound around the outer side of the corresponding hot pressing rollers 6. A cover 8 is fixedly connected to the front side of the frame 1. A cleaning mechanism 5 is provided between the cover 8 and the two hollow cylinders 51. Six laminating rollers 701 are rotatably arranged inside the frame 1. A pressure-adjustable laminating mechanism 7 is provided between the frame 1 and the six laminating rollers 701.

[0026] As a further aspect of this utility model, the cleaning mechanism 5 includes a drive motor 58 fixedly connected to one side of the cover 8 and a gear 54 fixedly sleeved on the outside of the hollow cylinder 51. The two gears 54 mesh with each other. A worm 57 is fixedly connected to the output shaft of the drive motor 58. A fan blade 56 is fixedly connected to the outside of the worm 57. A worm wheel 55 is fixedly sleeved on the outside of the front hollow cylinder 51. The worm 57 meshes with the worm wheel 55. Several fine brushes 52 are fixedly connected to the outside of the hollow cylinder 51. Multiple dust suction holes 53 are opened on the outside of the hollow cylinder 51. The fine brushes 52 and the dust suction holes 53 are arranged in a crisscross pattern. The cover 8 is connected to the front ends of the two hollow cylinders 51. An air outlet is fixedly connected to one side of the cover 8. A dust bag 59 is fixedly connected to the air outlet.

[0027] The above scheme is adopted as follows: Before lamination, the drive motor 58 drives the worm gear 57 to rotate, and the worm gear 57 drives the worm wheel 55 and a hollow cylinder 51 to rotate. Through the meshing transmission of two gears 54, the two hollow cylinders 51 are driven to rotate in opposite directions. The two hollow cylinders 51 drive the rotation of multiple fine brushes 52, which can simultaneously clean the dust and impurities attached to the front and back of the board, so as to avoid affecting the effect of lamination. At the same time, the worm gear 57 drives the fan blades 56 to rotate, which can suck the cleaned dust and impurities into the dust suction hole 53, the hollow cylinder 51 and the cover 8, and finally be sucked into the dust bag 59 for collection and treatment.

[0028] As a further aspect of this utility model, the pressure-adjustable film pressing mechanism 7 includes two cylinders 706, which are respectively fixedly connected to the top inner wall and the bottom inner wall of the frame 1. A servo motor 710 is fixedly connected to one side of the cylinder 706, and a drive bevel gear 711 is fixedly connected to the output shaft of the servo motor 710. A lifting screw 713 is rotatably connected to the inner wall of the two cylinders 706 on the side away from each other. A driven bevel gear 712 is fixedly sleeved on the outer side of the lifting screw 713. The drive bevel gear 711 meshes with the driven bevel gear 712. A lifting column 707 is threaded on the outer side of the lifting screw 713.

[0029] As a further feature of this invention, a pressure sensor 705 is fixedly connected to the bottom end of the lifting column 707, and a movable plate 704 is fixedly sleeved on the outside of the pressure sensor 705. Two mounting plates 702 are fixedly connected to the inside of the movable plate 704, and six pressure rollers 701 are rotatably connected between the corresponding two mounting plates 702.

[0030] The above scheme is adopted as follows: According to the needs of film lamination, the servo motor 710 is started. The servo motor 710 drives the rotation of the active bevel gear 711, which in turn drives the rotation of the driven bevel gear 712 and the lifting screw 713. Under the limit of the limit block 708, the lifting screw 713 drives the lifting column 707 and the pressure sensor 705 to move closer to the plate. The pressure sensor 705 can detect the pressure of the film lamination. When the requirements are met, the pressure sensor 705 sends a signal to the controller (not shown in the figure). The controller then shuts off the servo motor 710, thereby adjusting the pressure of the film lamination. This not only improves the effect of the film lamination roller 701 on the film 4 but also improves the versatility of the device.

[0031] As a further feature of this invention, four connecting plates 703 are fixedly connected to the inner side of the movable plate 704, and two mounting plates 702 are respectively fixedly connected to the bottom of the corresponding connecting plates 703, which facilitates the support and fixation of the mounting plates 702.

[0032] As a further feature of this invention, limit grooves 714 are provided on both inner walls of the cylinder 706. Limit blocks 708 are slidably sleeved in the limit grooves 714. The two limit blocks 708 are fixedly connected to both sides of the lifting column 707, which helps to limit the lifting column 707 and prevent it from rotating together with the lifting screw 713.

[0033] As a further feature of this invention, two telescopic rods 709 are fixedly connected to the inner top wall and the inner bottom wall of the frame 1. The ends of the four telescopic rods 709 that are close to each other are fixedly connected to the corresponding moving plates 704, which facilitates the guidance of the moving plates 704 and makes their movement more stable and smooth.

[0034] In this invention, during use, four conveying rollers 2 transport the panels used for processing panel furniture to the right. Before lamination, a drive motor 58 drives the rotation of a worm gear 57, which in turn drives the rotation of a worm wheel 55 and a hollow cylinder 51. Through the meshing transmission of two gears 54, the two hollow cylinders 51 are driven to rotate in opposite directions. The two hollow cylinders 51 drive the rotation of multiple fine brushes 52, thereby simultaneously cleaning the dust and impurities attached to both sides of the panels, preventing them from affecting the lamination effect later. At the same time, the worm gear 57 drives the rotation of a fan blade 56, which sucks the cleaned dust and impurities into the suction hole 53, the hollow cylinder 51, and the cover 8, and finally into the dust bag 59 for collection. Two film rollers 3 provide a film 4 to the hot press roller 6. The two hot press rollers 6 heat-press the film 4 onto the surface. On both sides of the sheet, double-sided lamination is achieved, improving the efficiency of sheet lamination. After hot pressing, the sheet continues to be conveyed to the right to the area of ​​the lamination roller 701. According to the lamination requirements, the servo motor 710 is started. The servo motor 710 drives the rotation of the active bevel gear 711, which in turn drives the rotation of the driven bevel gear 712 and the lifting screw 713. Under the limit of the limit block 708, the lifting screw 713 drives the lifting column 707 and the pressure sensor 705 to move closer to the sheet. The pressure sensor 705 can detect the pressure of the lamination film. When the requirements are met, the pressure sensor 705 sends a signal to the controller (not shown in the figure). The controller then turns off the servo motor 710, thereby adjusting the pressure of the lamination film. This not only improves the lamination effect of the lamination roller 701 on the film 4, but also improves the versatility of the device.
