Description

Technical Field

[0001] The utility model relates to the technical field of flat pasting equipment, in particular to a cold and hot glue flat pasting, covering and pressing integrated machine. Background Art

[0002] After the furniture board is produced, it needs to be coated on the surface. The coating treatment can ensure the furniture's smoothness for a long time and extend its service life. Different boards need to be pasted with thin films, which are mainly used to protect the board surface, and some boards need to be pasted with thick films. Thick films are mainly some decorative films with patterns on the board surface, which are used to protect and decorate the boards. Board film pasting is generally achieved through film pasting (flat pasting) equipment, and some board flat pasting machines can only past thin films on boards, not thick films. If thick films are to be pasted, other equipment is required, and the versatility is poor.

[0003] In addition, most of the current flat laminating machines apply glue on the board and then cover the film on the surface of the board for pressing. When the thickness of the board is thin, there is a high probability that the board will be rolled up on the glue coating roller due to glue adhesion. Therefore, most of the existing flat laminating machines find it difficult to stably produce thin plate products.

[0004] The technical problem to be solved by the utility model is: how to solve the problems of bloated volume, poor versatility and poor production stability of existing gluing, laminating and coating equipment. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide an all-in-one cold and hot glue flat laminating, coating and pressing machine, which can realize operations such as gluing, pressing and coating on the same device, has a compact structure, and can also enable the flat laminating process of thin plate products to be produced stably.

[0006] The technical scheme adopted by the utility model is: a cold and hot glue flat laminating and pressing machine, comprising a frame, a film placing mechanism, a glue coating mechanism and a pressing mechanism respectively installed on the frame, the film placing mechanism comprises a first air expansion shaft and a second air expansion shaft rotatably connected to the frame, the first air expansion shaft is used to load a thick film, and the first air expansion shaft is used to load a protective film, the pressing mechanism comprises an upper pressing roller and a lower pressing roller arranged opposite to each other up and down, the upper pressing roller and the lower pressing roller are rotatably connected to the frame, and the upper pressing roller can slide on the frame toward or away from the lower pressing roller;

[0007] The glue coating mechanism includes a glue coating roller, a glue control roller and a film extrusion roller rotatably arranged on a frame. The glue control roller and the film extrusion roller are arranged on the side of the glue coating roller, and the glue control roller and the film extrusion roller are slidably connected to the frame. The glue coating mechanism also includes a glue control power part and a film extrusion power part installed on the frame. The glue control power part drives the glue control roller to approach or move away from the glue coating roller, and the film extrusion power part drives the film extrusion roller to approach or move away from the glue coating roller.

[0008] The hot and cold glue flat laminating, coating and laminating all-in-one machine of the present application organically integrates the film placing mechanism, the glue coating mechanism and the laminating mechanism on a frame, and can realize the processes of flat laminating, laminating and coating on one device, which is conducive to making the device structure more compact, more functional and more versatile. In addition, by setting the glue coating roller as a heatable glue coating roller, hot and cold glue flat laminating can be realized, and the use is flexible and changeable.

[0009] In addition, compared with the traditional laminating machine that applies glue to the plate, the equipment of the present application applies glue on the thick film by passing the thick film between the film extrusion roller and the glue coating roller, instead of applying the glue on the plate and then laminating the thick film and the plate together through the upper pressing roller and the lower pressing roller. This can prevent thin plate workpieces from being rolled into the glue coating roller when gluing, thereby improving the stability of the flat laminating production of thin plate products.

[0010] In some embodiments, the glue coating mechanism further includes a glue gun installed on the side of the glue coating roller, and the glue gun is used to spray glue onto the surface of the glue coating roller.

[0011] By adopting the above technical solution, the glue gun can be used to better control the glue amount, improve the utilization rate of glue and reduce waste.

[0012] In some embodiments, a glue receiving basin is provided at the bottom of the glue coating roller and the glue controlling roller.

[0013] By adopting the above technical solution, the glue receiving basin can receive the glue dripping from the glue coating roller and the glue control roller, thereby preventing the glue from contaminating other parts of the equipment.

[0014] In some embodiments, the glue coating mechanism also includes a first horizontal slider and a second horizontal slider which are slidably connected to the frame, the first horizontal slider is sleeved on both ends of the glue control roller, and the glue control power piece is transmission connected to the first horizontal slider, the second horizontal slider is sleeved on both ends of the film extrusion roller, and the film extrusion power piece is transmission connected to the second horizontal slider.

[0015] By adopting the above technical scheme, the first horizontal slider is pushed to slide by the glue control power part, thereby adjusting the distance between the glue control roller and the glue coating roller, thereby adjusting the thickness of the glue coating; similarly, the second horizontal slider is driven to slide by the film extrusion power part, thereby adjusting the distance between the film extrusion roller and the glue coating roller. During the gluing process, the film extrusion roller is pushed toward the glue coating roller to keep the thick film in contact with the glue coating roller to ensure the gluing effect. When passing the film, the film extrusion roller is separated from the glue coating roller to facilitate the film to pass through between the film extrusion roller and the glue coating roller.

[0016] In some embodiments, the glue coating roller and the glue control roller rotate in opposite directions.

[0017] By adopting the above technical solution, the glue can be evenly distributed on the glue coating roller.

[0018] In some embodiments, the pressing mechanism further includes a lifting platform slidably connected to the frame, the upper pressing roller is rotatably connected to the lifting platform, and a lifting power component for driving the lifting platform to move up and down is installed on the frame.

[0019] By adopting the above technical solution, the distance between the upper pressing roller and the lower pressing roller can be adjusted according to the thickness of the workpiece, so that the distance between the upper pressing roller and the lower pressing roller matches the thickness of the plate.

[0020] In some embodiments, the pressing mechanism also includes a lifting slider slidably connected to the lifting platform, the lifting slider is sleeved on both ends of the upper pressing roller, and the lifting platform is provided with a pressing power component transmission-connected to the lifting slider, the pressing power component drives the upper pressing roller to maintain contact with the workpiece.

[0021] By adopting the above technical solution, the pressing power part cooperates with the lifting slider to enable the upper pressing roller to apply appropriate pressure to the plate and the thick film, thereby ensuring the lamination effect of the plate and the thick film.

[0022] In some embodiments, the film placing mechanism further includes a plurality of film guide rollers, and each of the film guide rollers is arranged inside the frame at intervals.

[0023] By adopting the above technical solution, the number and position of the film guide rollers can be set according to the path of the film, so that the film can travel along a preset path.

[0024] In some embodiments, a plurality of supporting rollers are arranged at intervals inside the frame, and the top of each supporting roller is in the same horizontal plane as the top of the lower pressing roller.

[0025] With the above technical solution, the support rollers are used to support the plate to prevent the plate from bending due to its own gravity.

[0026] In some embodiments, a folding roller frame is hingedly connected to the feed end of the frame.

[0027] By adopting the above technical solution, the folding roller frame can be unfolded to receive the plate when necessary, and the folding roller frame can be stored to reduce the size of the equipment when not needed. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] See also Figures 1 to 4, which is a hot and cold glue flat laminating and pressing machine 100 of a preferred embodiment of the utility model, includes a frame 10, a film placing mechanism 20, a glue coating mechanism 30 and a pressing mechanism 40 respectively installed on the frame 10, the film placing mechanism 20 includes a first air expansion shaft 21 and a second air expansion shaft 22 rotatably connected to the frame 10, the first air expansion shaft 21 is used to load a thick film, and the first air expansion shaft 21 is used to load a protective film, the glue coating mechanism 30 is used to apply glue to the surface of the thick film, and the pressing mechanism 40 includes an upper pressing roller 41 and a lower pressing roller 42 arranged opposite to each other in an upper and lower direction, the upper pressing roller 41 and the lower pressing roller 42 are rotatably connected to the frame 10, and the upper pressing roller 41 can slide on the frame 10 toward or away from the lower pressing roller 42.

[0037] Specifically, the glue coating mechanism 30 includes a glue coating roller 31, a glue control roller 32 and a film extrusion roller 33 which are rotatably arranged on the frame 10. The glue control roller 32 and the film extrusion roller 33 are arranged on the side of the glue coating roller 31, and the glue control roller 32 and the film extrusion roller 33 are slidingly connected to the frame 10. The glue coating mechanism 30 also includes a glue control power part 35 and a film extrusion power part 36 installed on the frame 10. The glue control power part 35 drives the glue control roller 32 to approach or move away from the glue coating roller 31, and the film extrusion power part 36 drives the film extrusion roller 33 to approach or move away from the glue coating roller 31.

[0038] Furthermore, the glue coating mechanism 30 also includes a glue gun 34 installed on the side of the glue coating roller 31, and the glue gun 34 is used to spray glue on the surface of the glue coating roller 31. Preferably, the glue gun 34 sprays glue between the glue coating roller 31 and the glue control roller 32. The use of the glue gun 34 for gluing can better control the amount of glue, improve the utilization rate of glue, and reduce waste. It should be noted that the number of glue guns 34 and the distance between two adjacent glue guns 34 can be adjusted according to actual conditions, and are not limited to the number and position shown in the accompanying drawings.

[0039] In other embodiments, the gluing operation may also be achieved by immersing the bottom of the glue coating roller 31 in a glue basin.

[0040] Preferably, in order to prevent glue from dripping from the glue control roller 32 and the glue coating roller 31, a glue receiving basin 39 is provided at the bottom of the glue coating roller 31 and the glue control roller 32. The glue receiving basin 39 can receive the glue dripping from the glue coating roller 31 and the glue control roller 32 to prevent the glue from contaminating other parts of the equipment.

[0041] like Figure 1 and Figure 3As shown, the glue coating mechanism 30 further includes a first horizontal slider 37 and a second horizontal slider 38 which are slidably connected to the frame 10. The first horizontal slider 37 is sleeved on both ends of the glue control roller 32, and the glue control power member 35 is transmission-connected to the first horizontal slider 37. The second horizontal slider 38 is sleeved on both ends of the film extrusion roller 33, and the film extrusion power member 36 is transmission-connected to the second horizontal slider 38. The glue control power member 35 pushes the first horizontal slider 37 to slide, thereby adjusting the distance between the glue control roller 32 and the glue coating roller 31, thereby adjusting the thickness of the glue coating; similarly, the film extrusion power member 36 drives the second horizontal slider 38 to slide, thereby adjusting the distance between the film extrusion roller 33 and the glue coating roller 31. During the gluing process, the film extrusion roller 33 is pushed toward the glue coating roller 31, so that the thick film is kept in contact with the glue coating roller 31 to ensure the gluing effect. When the film is passed through, the film extrusion roller 33 is separated from the glue coating roller 31, so that the film passes between the film extrusion roller 33 and the glue coating roller 31.

[0042] In this embodiment, the rotation directions of the glue coating roller 31 and the glue control roller 32 are opposite. This arrangement can make the glue evenly distributed on the glue coating roller 31. Of course, in other embodiments, the rotation directions of the glue coating roller 31 and the glue control roller 32 can also be the same, and the rotation directions of the two can be selected according to the characteristics of the glue.

[0043] In this embodiment, the glue control power part 35 is a worm gear reducer with a hand wheel, and in order to make the movements of both ends of the glue control roller 32 consistent when the two ends move in translation, the first horizontal sliders 37 at both ends of the glue control roller 32 are connected by a synchronization rod to achieve synchronous sliding. In other embodiments, other power components that can achieve the same function can also be used, such as motors, pneumatic push rods, electric push rods, hydraulic push rods, etc. In this embodiment, the film extrusion power part 36 is a cylinder.

[0044] like Figure 1 and Figure 2 As shown, the pressing mechanism 40 also includes a lifting platform 43 that is slidably connected to the frame 10 for lifting and lowering, the upper pressing roller 41 is rotatably connected to the lifting platform 43, and a lifting power member 44 that drives the lifting platform 43 to lift and lower is installed on the frame 10. This arrangement can adjust the distance between the upper pressing roller 41 and the lower pressing roller 42 according to the thickness of the workpiece, so that the distance between the upper pressing roller 41 and the lower pressing roller 42 matches the thickness of the plate. In order to keep the movements of the two ends of the upper pressing roller 41 consistent when lifting and lowering, the lifting platforms 43 at both ends of the upper pressing roller 41 are connected by a synchronization rod. In this embodiment, the lifting power member 44 is a motor, and the motor drives the lifting platform 43 to rise and fall through a screw and a screw nut.

[0045] Furthermore, the laminating mechanism 40 further includes a lifting slider 45 slidably connected to the lifting platform 43, the lifting slider 45 is sleeved on both ends of the upper laminating roller 41, and the lifting platform 43 is provided with a laminating power member 46 which is transmission-connected to the lifting slider 45, and the laminating power member 46 drives the upper laminating roller 41 to keep in contact with the workpiece. The laminating power member 46 cooperates with the lifting slider 45 to enable the upper laminating roller 41 to apply appropriate pressure to the plate and the thick film, thereby ensuring the laminating effect of the plate and the thick film. Preferably, the laminating power member 46 is a cylinder or a hydraulic cylinder.

[0046] In this embodiment, the number of the upper pressing rollers 41 and the number of the lower pressing rollers 42 are both two, and each upper pressing roller 41 corresponds to one lower pressing roller 42 .

[0047] Preferably, each of the glue coating roller 31, the glue control roller 32, the upper pressing roller 41 and the lower pressing roller 42 is driven by a motor respectively, so that the rotation speed of each roller can be controlled according to the actual situation, so that the control of the equipment during operation is more accurate. Of course, in other embodiments, multiple rollers can also be driven by one motor to rotate, which can reduce the number of power components and reduce costs.

[0048] Preferably, in order to facilitate loading and unloading of rolled film materials, the first air expansion shaft 21 and the second air expansion shaft 22 are arranged at one end of the frame 10 .

[0049] In this embodiment, the film placing mechanism 20 further includes a plurality of film guide rollers 23, each of which is arranged at intervals inside the frame 10. The number and position of the film guide rollers 23 can be set according to the actual film path, so that the film can travel along a preset path.

[0050] Preferably, a plurality of support rollers 11 are arranged at intervals inside the frame 10, and the top of each support roller 11 is at the same horizontal plane as the top of the lower pressing roller 42. The support rollers 11 are used to support the plate to prevent the plate from bending due to its own gravity.

[0051] In one embodiment, the feeding end of the frame 10 is also hinged with a folding roller frame 12, which can be unfolded to receive the plate when needed, and can be stored to reduce the size of the equipment when not needed. Preferably, the folding roller frame 12 is driven by a cylinder to automatically unfold or fold.

[0052] Preferably, in order to facilitate the replacement of the membrane material and each working roller, a crane 13 is provided on the top of the frame 10, and the crane 13 can be used to hoist the membrane material or the working roller.

[0053] The hot and cold glue flat laminating, coating and laminating all-in-one machine 100 of the present application organically integrates the film placing mechanism 20, the glue coating mechanism 30 and the laminating mechanism 40 on the frame 10, and can realize the processes of flat laminating, laminating and coating on one device. After the thick film is pulled out, it is glued by the glue coating mechanism 30, and then the thick film and the plate are pressed into one by the laminating mechanism 40. The pressed product is then coated with a protective film and sent out of the device. This is conducive to making the device structure more compact, more functional and more versatile. In addition, by setting the glue coating roller 31 as a heatable glue coating roller 31, hot and cold glue flat laminating can be achieved, and the use is flexible and changeable.

[0054] Compared with the traditional laminating machine that applies glue to the plate, the hot and cold glue flat laminating, coating and pressing machine 100 of the present application passes the thick film between the film extrusion roller 33 and the glue coating roller 31, so that the glue is coated on the thick film, instead of coating the glue on the plate, and then the thick film and the plate are pressed and flattened together through the upper pressing roller 41 and the lower pressing roller 42. In this way, thin plate workpieces can be prevented from being rolled into the glue coating roller 31 when being glued, and the stability of the flat laminating production of thin plate products can be improved.
