Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a laminating pressing mechanism of a laminating machine. Background Art

[0002] The laminating machine's laminating and pressing mechanism is responsible for evenly and tightly pressing the film onto the covering material, such as paper or textiles. It needs to ensure that the film is tightly bonded to the covering material to avoid the generation of bubbles and wrinkles. The mechanism needs to precisely control temperature, pressure and speed to ensure consistent laminating results. At the same time, it is required to have high strength and durability to adapt to long-term, high-frequency operation.

[0003] The utility model with the authorization publication number CN210190821U provides a laminating and pressing mechanism of a laminating machine, which belongs to the technical field of "laminating machine". The protected claim: "It includes a pressing frame and a second lifting mechanism, a first lifting mechanism is provided inside one side of the pressing frame, and a rack is provided on one side of the first lifting mechanism, one side of the rack is meshed with a gear, and one side of the gear is connected to an upper pressing wheel through the pressing frame through a drive shaft, and a partition is fixed inside the pressing frame below the first lifting mechanism. In the utility model, the device is provided with a first lifting mechanism and a second lifting mechanism inside the pressing frame, and the first lifting mechanism and the second lifting mechanism are provided with a screw, a gear and a rack. By manually rotating the screw, the screw is raised or lowered to a certain height. The bottom of the screw is connected to the upper pressing wheel through a bearing, and the upper pressing wheel is meshed with a gear and a rack on one side, and can rotate with the movement of the screw, so that the upper pressing wheel can easily adjust the distance with the lower pressing wheel, which is convenient for the pressing operation after lamination."

[0004] In this device, although the tightness of the pressing can be adjusted by adjusting the spacing of the pressing mechanism, the pressing area between the pressing mechanism and the film cannot be increased, and it cannot ensure that the film is evenly distributed on the surface of the coated material to form a smooth, wrinkle-free covering layer. It also cannot reduce the pressing area and cannot perform enhanced treatment in special areas where bubbles are generated. For this reason, we propose a laminating pressing mechanism for a laminating machine. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1-4 As shown, in this embodiment, a laminating and pressing mechanism of a laminating machine includes a base frame 1 and a pressing assembly 2, and the pressing assembly 2 is arranged in the base frame 1;

[0024] The pressing assembly 2 includes a rotating seat 201, a bidirectional motor 204 and a second press fitter 4; the rotating seat 201 is arranged in the base frame 1, and a rotating shaft 202 is rotatably connected between the rotating seat 201 and the base frame 1, and the inner bottom surface of the base frame 1 is rotatably connected to a hydraulic rod 203, and the driving end of the hydraulic rod 203 is rotatably connected to the bottom of the rotating seat 201; the bidirectional motor 204 is fixedly connected to the inner bottom surface of the rotating seat 201, and the driving ends on both sides of the bidirectional motor 204 are fixedly connected to a rotating rod 205, and the outer ends of the two rotating rods 205 are fixedly connected to a first bevel gear 206, and the outer sides of the two first bevel gears 206 are meshed with a second bevel gear 207, and the two second bevel gears 207 are fixedly connected with a screw 208, and the bottom ends of the two screws 208 are rotatably connected to the inner bottom surface of the rotating seat 201, and the upper ends of the two screws 208 are threadedly connected to the first press fitter 3; the second press fitter 4 is fixedly connected to the top of the base frame 1.

[0025] During the specific implementation, the film is inserted between the first laminator 3 and the second laminator 4, and then the two bidirectional motors 204 are started. The two bidirectional motors 204 drive the two sets of rotating rods 205 to rotate synchronously in the same direction, thereby driving the two sets of first bevel gears 206 to rotate. The rotation of the two sets of first bevel gears 206 drives the two sets of second bevel gears 207 to rotate. The rotation of the two sets of second bevel gears 207 drives the two sets of screws 208 with opposite threads to rotate. The rotation of the two sets of screws 208 can drive the first laminator 3 to rise and fall under the limit of the slider 6 and the slide groove 5 through the four vertical plates 301 to adapt to different thicknesses. The film can also enhance the pressing pressure by synchronously starting multiple hydraulic rods 203. Multiple hydraulic rods 203 synchronously drive one end of the rotating seat 201 to rotate and lift under the action of two rotating shafts 202 as fulcrums, that is, one end of the first press 3 is rotated and lifted, so that the pressing area between the first press 3 and the second press 4 is reduced, and the special area where bubbles are generated can be strengthened. Vice versa, the first press 3 is rotated to a position parallel to the second press 4, which can increase the pressing area to ensure that the film is evenly distributed on the surface of the coating material to form a smooth, wrinkle-free covering layer.

[0026] In addition, it should be noted that the pressing belt 306 is made of high-hardness rubber material and has a smooth surface.

[0027] Furthermore, the two screw rods 208 in each group have opposite thread directions. Only when the two screw rods 208 have opposite thread directions can the first press-fit device 3 be driven to rise and fall synchronously.

[0028] like Figure 1-2 As shown, further, the base frame 1 includes a base plate 101; four support plates 102 are fixedly connected to the base plate 101, the outer ends of the two rotating shafts 202 are respectively rotatably connected to the inner sides of two opposite support plates 102, and the second presser 4 is fixedly connected between the four support plates 102. By setting four support plates 102, the second presser 4 can be fixed, and the first presser 3 can be set.

[0029] like Figure 2-3 As shown, further, two groups of slide grooves 5 are opened on the inner side of the rotating seat 201, and the four vertical plates 301 of the first press 3 are fixedly connected to the outer sides with sliders 6, and the four sliders 6 are respectively slidably connected in the four slide grooves 5. The rotation of the two groups of screws 208 can drive the first press 3 to rise and fall through the four vertical plates 301 under the limit of the sliders 6 and the slide grooves 5. The sliders 6 and the slide grooves 5 are set for limit to avoid deviation.

[0030] Example 2

[0031] like Figure 4 As shown, the first press 3 and the second press 4 each include a vertical plate 301; two roller bodies 302 are rotatably connected between the four vertical plates 301, and both ends of the two roller bodies 302 are fixedly sleeved with driving gears 303, and the outer sides of the two vertical plates 301 are fixedly connected with driving motors 304, and the driving ends of the two driving motors 304 are respectively fixedly connected to one end of the corresponding two roller bodies 302, and the outer sides of the driving gears 303 on both sides are meshed with chains 305, and the outer sides of the two roller bodies 302 are sleeved with pressing belts 306.

[0032] During specific implementation, the specific structures of the first laminator 3 and the second laminator 4 are the same. The driving motor 304 is started, and the driving motor 304 drives the driving gear 303 to rotate. The rotation of the driving gear 303 drives one roller 302 to rotate, and at the same time, under the linkage action of the chain 305, the other roller 302 is synchronously driven to rotate. The synchronous rotation of the two rollers 302 can drive the laminating belt 306 to rotate. The driving directions of the driving motors 304 in the first laminator 3 and the second laminator 4 are opposite to facilitate laminating the films.

[0033] like Figure 1 As shown, further, a guide plate 7 is fixedly connected to one side of the rotating seat 201. By providing the guide plate 7, the pressed film can slide out of the device along the guide plate 7.

[0034] Working principle: First, insert the film between the first laminator 3 and the second laminator 4, then start the two bidirectional motors 204, the two bidirectional motors 204 synchronously drive the two sets of rotating rods 205 to rotate in the same direction, which in turn drives the two sets of first bevel gears 206 to rotate, the two sets of first bevel gears 206 rotate, the two sets of second bevel gears 207 rotate, the two sets of second bevel gears 207 rotate and drive the two sets of screws 208 with opposite threads to rotate, the rotation of the two sets of screws 208 can drive the first laminator 3 to move up and down through the four vertical plates 301 under the limit of the slider 6 and the slide 5 to adapt to different thicknesses The film can be tightened and the pressing pressure can be enhanced by synchronously starting multiple hydraulic rods 203. Multiple hydraulic rods 203 synchronously drive one end of the rotating seat 201 to rotate and lift under the action of two rotating shafts 202 as fulcrums, that is, one end of the first press 3 is rotated and lifted, so that the pressing area between the first press 3 and the second press 4 is reduced, and the special area where bubbles are generated can be strengthened. Vice versa, the first press 3 is rotated to a position parallel to the second press 4, which can increase the pressing area to ensure that the film is evenly distributed on the surface of the coating material to form a smooth, wrinkle-free covering layer.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
