Description

Technical Field

[0001] This utility model belongs to the field of laminating machine technology, and specifically relates to a fixing mechanism for a laminating machine. Background Technology

[0002] Laminating machines can be divided into two main categories: instant laminating machines and pre-coating laminating machines. They are specialized equipment used for paper, boards, and film lamination. After being pressed together by rubber rollers, they form a paper-plastic composite product.

[0003] In existing laminating machines, the sheets are prone to shifting during the conveyor belt transport process due to various factors, such as minor vibrations of the equipment itself and uneven friction of the conveyor belt. Once the conveying direction of the sheet deviates from the predetermined track, it can easily cause the sheet to shift or tilt during transport, making it difficult for the film to adhere accurately to the sheet. This results in deviations in the laminating position, causing problems such as laminating wrinkles and uneven edges, which seriously affect product quality and reduce the product qualification rate. In addition, operators need to frequently intervene and adjust the conveying direction of the sheet, which not only increases labor intensity but also greatly reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fixing mechanism for a laminating machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing mechanism for a laminating machine, comprising:

[0006] The base has uprights connected to both sides of its top, and one end of each upright is connected to a frame.

[0007] A conveyor plate is connected to the base surface for conveying the plate. One side of the upright plate is provided with a guide assembly for fixing and guiding the conveying direction of the plate. The guide assembly includes a cylinder and a guide frame. There are two sets of cylinders, which are respectively located on the two sets of upright plates. The piston rod of the cylinder moves through the upright plate and is connected to the guide frame. Several guide rollers are rotatably connected inside the guide frame through bearings.

[0008] A cleaning frame, connected between two sets of uprights, is used to clean the coated panels.

[0009] Preferably, one end of the guide frame is connected to an inclined plate, and several guide rollers are rotatably connected inside the inclined plate via bearings.

[0010] Preferably, brush plates are connected to both the top and bottom of the cleaning frame.

[0011] Preferably, both ends of the guide frame are connected to guide rods, and the other end of the guide rod slides through the upright plate.

[0012] Preferably, a transmission gear is internally engaged at one end of the conveyor plate, and a driven gear is engaged at the other end. A motor is provided on the surface of the base, and the output shaft of the motor rotates through the base and connects to the transmission gear.

[0013] Preferably, a film roll is rotatably connected to the frame via a bearing, and a guide roller is rotatably connected to the bottom of the film roll via a bearing.

[0014] Preferably, a coating roller for rolling and coating the sheet is rotatably connected to one side of the bottom of the guide roller via a bearing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) By setting up a guide assembly, the guide frame is moved by the cylinder, and the guide roller in the guide frame fixes the conveying direction of the board. This effectively avoids the board from shifting or tilting due to factors such as equipment vibration and uneven friction of the conveyor belt during the conveying process, so that the film and the board can be accurately bonded, greatly reducing problems such as film wrinkles and uneven edges, significantly improving the product qualification rate and improving the product quality.

[0017] (2) The brush plates connected to the top and bottom of the cleaning frame can clean the coated board and remove dust, debris and other impurities that may be generated on the board surface during the coating process, further ensuring the quality of the coating and making the coated board surface cleaner and more beautiful.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The shown is a fixing mechanism for a laminating machine, comprising:

[0025] Base 1, with upright plates 2 connected to both sides of the top of the base 1 and a frame 3 connected to one end of the upright plates 2;

[0026] The conveying plate 4 is connected to the surface of the base 1 for conveying the plate 5. The upright plate 2 has a guide assembly on one side for fixing and guiding the conveying direction of the plate 5. The guide assembly includes a cylinder 6 and a guide frame 7. The cylinder 6 is provided in two sets and is respectively provided on the two sets of upright plates 2. The piston rod of the cylinder 6 moves through the upright plate 2 and is connected to the guide frame 7. Several guide rollers 8 are rotatably connected inside the guide frame 7 through bearings.

[0027] The cleaning frame 9 is connected between two sets of upright plates 2 and is used to clean the film-coated board 5.

[0028] One end of the guide frame 7 is connected to an inclined plate 10, and several guide rollers 8 are rotatably connected inside the inclined plate 10 via bearings.

[0029] The cleaning frame 9 has brush plates 11 connected to both the top and bottom.

[0030] Both ends of the guide frame 7 are connected to guide rods 12, and the other end of the guide rods 12 slides through the upright plate 2. The guide rods 12 can guide the movement direction of the guide frame 7 when the cylinder 6 pushes the guide frame 7, restrict the movement direction of the guide frame 7, and make it only move along the axial direction of the guide rods 12, so as to avoid unstable situations such as shaking or deviation when the guide frame 7 moves.

[0031] One end of the conveyor plate 4 is internally engaged with a transmission gear 13, and the other end is engaged with a driven gear 14. The surface of the base 1 is provided with a motor 15, and the output shaft of the motor 15 rotates through the base 1 and connects with the transmission gear 13.

[0032] Inside the frame 3, a film-winding roller 16 is rotatably connected via bearings, and a guide roller 17 is rotatably connected via bearings at the bottom of the film-winding roller 16. A coating roller 18 for rolling and coating the board 5 is rotatably connected via bearings on one side of the bottom of the guide roller 17. Since the coating roller 18 is rotatably connected via bearings, when the board 5 comes into contact with the coating roller 18, the friction force can drive the coating roller 18 to move flexibly. At this time, the film 19 conveyed from the film-winding roller 16 through the guide roller 17 comes into contact with the board. Under the rolling action of the coating roller 18, the film 19 is tightly adhered to the surface of the board 5, completing the coating operation. During the rolling process, the pressure applied by the coating roller 18 is evenly distributed on the contact surface of the board 5 and the film 19, so that the two are fully bonded and problems such as bubbles and wrinkles are avoided.

[0033] In operation, the fixing mechanism of this laminating machine first places the sheet material 5 on the conveyor plate 4, with one end passing through the cleaning frame 9. Then, the motor 15 is started by an external controller. The output shaft of the motor 15 drives the transmission gear 13 to rotate. The transmission gear 13 meshes with the conveyor chain inside the conveyor plate 4, thereby driving the conveyor plate 4 to rotate and convey the sheet material. The driven gear 14 meshes with the other end of the conveyor plate 4, providing auxiliary support and stabilizing the conveying process. During the conveying of the sheet material 5, the surface of the sheet material 5 entering the cleaning frame 9 can be cleaned by the brush plates 11 at the top and bottom of the cleaning frame 9. To remove any dust, debris, or other impurities, ensuring the surface of the board 5 is clean and tidy before lamination, multiple inductive proximity sensors (not shown in the attached diagram) are symmetrically installed on the two sets of vertical plates 2. Under normal circumstances, the board 5 is located in the center of the conveyor plate 4 during transport, with the proximity sensors on both sides at equal distances from the board 5. The signals detected by the proximity sensors are relatively stable. When the board 5 shifts, the distance between the proximity sensor on one side decreases, while the distance on the other side increases. On the side with the smaller distance, the influence of the board 5 on the alternating magnetic field of the proximity sensor increases, affecting the transmission... The oscillation amplitude attenuation or frequency change detected by the sensor is more obvious; while on the side with greater distance, the effect is relatively weaker. The sensor transmits the detected signal changes to the control system (not shown in the attached figure). The control system determines whether the plate 5 has shifted and the direction and degree of the shift based on the difference in signals on both sides. Then, the control system controls the cylinder 6 to move according to the preset program after processing the electrical signal. The piston rod of the cylinder 6 pushes the guide frame 7 to move, so that the guide roller 8 inside the guide frame 7 approaches the plate 5. After the guide roller 8 contacts the plate 5, it fixes and guides the conveying direction of the plate 5, ensuring that the plate 5 is stably conveyed along the predetermined track. If the plate 5 shifts, the proximity sensor will detect it in time and adjust the extension and retraction of the piston rod of the cylinder 6 through the control system to move the guide frame 7 to the appropriate position and correct the conveying direction of the plate 5. The inclined plate 10 connected to one end of the guide frame 7 and the guide roller 8 inside it further enhance the guiding effect of the plate 5, so that the plate 5 can be initially aligned and guided before entering the main body of the guide frame 7. The guide rods 12 at both ends of the guide frame 7 slide in the vertical plate 2 to ensure the stability of the guide frame 7 during the movement and prevent its shaking from affecting the guiding accuracy.

[0034] The film-coating material is installed on the film-winding roller 16 inside the frame 3. The film-coating material is released from the film-winding roller 16, guided by the guide roller 17, and reaches the position of the film-coating roller 18. When the board 5 is conveyed to the bottom of the film-coating roller 18, the film-coating roller 18 rolls and coats the board 5, tightly adhering the film 19 to the surface of the board 5. The guide roller 17 plays the role of adjusting the conveying direction and tension of the film 19, ensuring that the film 19 can accurately cover the board 5, and ensuring the flatness and tension uniformity of the film 19 during the coating process.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
