Description

Technical Field

[0001] This utility model relates to a laminating machine, and more particularly to a double-sided feeding laminating and shearing integrated machine. Background Technology

[0002] In modern industrial production, double-sided laminating machines for boards are widely used in furniture manufacturing, building decoration, and many other fields. By applying a protective film to both sides of the board, the wear resistance, corrosion resistance, and aesthetics of the board can be effectively improved. Among these processes, the cutting step after lamination is a crucial link in the entire production process, as it determines the specifications and quality of the finished board.

[0003] However, in practical applications, the shearing devices of existing double-sided laminating machines for sheet materials often fail to cut completely, resulting in some sheets not being completely severed. This is due to two main reasons. First, sheet materials have thickness tolerances during production; different batches or even different parts of the same batch may have slight thickness variations. When thicker sheets enter the shearing device, the existing cutter hardness and shearing force are insufficient to cut them completely in one go. Second, prolonged high-frequency use leads to wear and dulling of the cutter blade, reducing shearing capacity. Furthermore, the lack of effective cutter wear detection and automatic compensation mechanisms prevents timely adjustment of shearing parameters after wear, further exacerbating the problem of incomplete cutting.

[0004] During the collection process, these incompletely cut boards can interfere with subsequent boards, causing them to shift or become stuck. This not only prevents the laminating film from adhering accurately to the board surface, resulting in quality defects such as bubbles and wrinkles, but also causes misaligned boards to fail to cut properly when entering the shearing device, leading to incompletely cut new boards and creating a vicious cycle. This severely impacts equipment operation, reduces production efficiency, increases downtime, and wastes boards, raising production costs. Furthermore, frequent equipment failures and production interruptions can cause significant economic losses and increase production management pressure for the company. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a double-sided feeding, coating and shearing integrated machine. This double-sided feeding, coating and shearing integrated machine can coat the board material on both sides and cut it into single sheets. It can also detect whether the board is completely cut, avoid the situation where the boards are connected, and effectively ensure the quality of the board.

[0006] To solve the above technical problems, the following technical solution is adopted:

[0007] A double-sided feeding, laminating, and shearing integrated machine includes a frame, a sheet material conveying device, a laminating device, a shearing device, a control device, and two film material conveying devices. The sheet material conveying device, laminating device, shearing device, control device, and film material conveying devices are respectively mounted on the frame. The sheet material conveying device, laminating device, and shearing device are arranged sequentially from front to back along the sheet material conveying direction. Both film material conveying devices are located in front of the laminating device and are respectively positioned on the upper and lower sides of the sheet material conveying device. The signal input terminals of the sheet material conveying device, laminating device, and shearing device are electrically connected to the corresponding signal output terminals of the control device. The machine is characterized by further including a shearing detection device, which is mounted on the frame and positioned between the laminating device and the shearing device. The signal output terminal of the shearing detection device is electrically connected to the corresponding signal input terminal of the control device.

[0008] In operation, the aforementioned double-sided feeding, laminating, and shearing integrated machine transports the sheet material via a sheet conveying device. As the laminating film is laminated onto the sheet, the film feeding roller, pulled forward by the laminating device and the sheet conveying device, continuously feeds out the film. Under the action of the laminating mechanism, the two films gradually adhere and are laminated onto the sheet. Finally, the laminated sheet is fed into the shearing device, which cuts the film into individual sheets, which fall to a collection location. During the shearing process, a cutting detection device monitors the sheet. If the sheet is not completely cut and shows signs of entanglement, the cutting detection device sends a signal to the control device, causing the control device to stop all devices from operating. This double-sided feeding, laminating, and shearing integrated machine can double-sidedly laminate and cut the sheet into individual sheets, and can detect whether the sheet is completely cut, preventing entanglement and effectively ensuring sheet quality.

[0009] The aforementioned control device can be a computer, a microcontroller, a programmable controller, etc.; the aforementioned sheet material conveying device can be multiple conveying rollers and a drive mechanism capable of driving the conveying rollers to rotate; the aforementioned laminating device can be two parallel composite rollers and a drive mechanism capable of driving the composite rollers to rotate, with a gap between the two composite rollers for the sheet material to pass through; the aforementioned shearing device can be a cutter and a drive mechanism for driving the cutter.

[0010] In a preferred embodiment, the shearing detection device includes a displacement sensor and a roller. The cavity of the displacement sensor is mounted on the frame, with the moving end of the displacement sensor facing downwards. The roller is rotatably disposed at the lower end of the moving end of the displacement sensor, and the position of the roller corresponds to that of the laminating device. After the laminated sheet material is self-coating, it is fed to the shearing device. During conveying, the rollers roll in contact with the surface of the sheet material. If the shearing device does not completely cut the sheet material, the uncut pieces will pull on the sheet material as it falls, causing it to warp. This warped material will then push up the moving end of the displacement sensor via the rollers, causing it to move a significant distance. The displacement sensor sends the detected displacement distance signal to the control device. If the displacement distance signal received by the control device exceeds the preset reasonable displacement distance (the sheet material will also slightly push up the moving end of the displacement sensor during normal conveying, so the control device has a preset reasonable displacement distance; within this reasonable displacement distance, the control device determines that no uncut material has occurred), the control device determines that the sheet material has not been completely cut, and at this point, the control device stops the equipment.

[0011] In a preferred embodiment, the film feeding device includes a film feeding roller and a rotation counting mechanism. The film feeding roller is rotatably mounted on the frame. The rotation counting mechanism includes a code disk and a proximity switch. The code disk is coaxially and fixedly connected to the corresponding film feeding roller. The code disk has a notch. The proximity switch is mounted on the frame, and its sensing area is aligned with the code disk. The signal output terminal of the proximity switch is electrically connected to the corresponding signal input terminal of the control device. During the lamination process, the two film feeding rollers rotate at the same speed. Therefore, the corresponding proximity switch will detect the signal at the same time for each revolution of the two film feeding rollers. When the detection time of the two proximity switches deviates, it indicates a difference in the rotation speed of the two film feeding rollers. The film on the slower-rotating film feeding roller is in an overstretched state. Continuing to feed the film will cause it to break. Therefore, when the control device detects a time difference in the detection signals of the two proximity switches, it can control the traction lamination mechanism to stop working, allowing the operator to promptly inspect and adjust the film feeding rollers. This configuration further ensures the lamination quality of the sheet material.

[0012] In a further preferred embodiment, the film conveying device further includes a film feeding roller fine-tuning mechanism. The film feeding roller is rotatably mounted on the frame via the corresponding film feeding roller fine-tuning mechanism. When the speed of the film feeding roller deviates, it is mostly due to a deviation in the position of the film feeding roller. Therefore, the film feeding roller can be fine-tuned using the film feeding roller fine-tuning mechanism to return it to the normal film feeding position and continue feeding, ensuring that the fed film material is aligned with the sheet material.

[0013] In a further preferred embodiment, the film feeding roller fine-tuning mechanism includes a mounting plate, a mounting shaft, and at least one guide adjustment assembly. The mounting shaft is rotatably mounted on the mounting plate, and the film feeding roller is connected to the corresponding mounting shaft. The mounting plate is movable inward and outward on the frame via the guide adjustment assembly. During adjustment, the corresponding guide adjustment assembly moves and adjusts the mounting plate, thereby adjusting the position of the film feeding roller.

[0014] In a further preferred embodiment, the guide adjustment assembly includes an adjusting rod and a compression spring. The mounting plate has at least one through hole, and the frame has at least one screw hole corresponding to the position of the through hole. The number of through holes is the same as the number of guide adjustment assemblies, and they correspond one-to-one. The outer end of the adjusting rod has a stop, and the inner end of the adjusting rod has a thread matching the screw hole. The adjusting rod can move inward and outward through the through hole, and the inner end of the adjusting rod is threadedly connected to the screw hole. The compression spring is sleeved on the adjusting rod, and the outer end of the compression spring is in close contact with the stop of the adjusting rod, while the inner end of the compression spring is connected to the mounting plate. During adjustment, by rotating the adjusting rod, the stop on the adjusting rod moves closer to or further away from the frame. At this time, the mounting plate moves closer to or further away from the frame under the action of the compression spring, thereby driving the film feeding roller to move accordingly. The adjusting rod can be a screw, wherein the head of the screw constitutes the stop.

[0015] In a further preferred embodiment, the guiding adjustment assembly further includes a guide sleeve, which is fixedly installed in the through hole, and the adjusting rod moves inward and outward through the guide sleeve. During adjustment, the adjusting rod can move along the guide sleeve.

[0016] In a further preferred embodiment, the inner end face of the mounting shaft or the end face of the film feeding roller is provided with a limiting protrusion, and the end face of the film feeding roller or the inner end face of the mounting shaft is provided with a limiting groove that matches the limiting protrusion. When the film feeding roller is connected to the mounting shaft, the limiting protrusion can be inserted into the limiting groove, thereby fixing the position of the film feeding roller.

[0017] The beneficial effects of this utility model are as follows: This double-sided feeding, coating and shearing integrated machine can coat the board material on both sides and cut it into single sheets. It can also detect whether the board is completely cut, avoid the situation where the boards are connected, and effectively ensure the quality of the board. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] like Figure 1-6 The double-sided feeding, laminating, and shearing integrated machine shown includes a frame 1, a sheet material conveying device 2, a laminating device 3, a shearing device 4, a control device, a shearing detection device 5, and two film material conveying devices 6. The sheet material conveying device 2, laminating device 3, shearing device 4, control device, shearing detection device 5, and film material conveying device 6 are respectively mounted on the frame 1. The sheet material conveying device 2, laminating device 3, shearing detection device 5, and shearing device 4 are arranged sequentially from front to back along the sheet material conveying direction. The two film material conveying devices 6 are both located in front of the laminating device 3, and the two film material conveying devices 6 are respectively arranged on the upper and lower sides of the sheet material conveying device 2. The signal input terminals of the sheet material conveying device 2, laminating device 3, and shearing device 4 are electrically connected to the corresponding signal output terminals of the control device, and the signal output terminal of the shearing detection device 5 is electrically connected to the corresponding signal input terminal of the control device.

[0026] In operation, the aforementioned double-sided feeding, laminating, and shearing integrated machine transports the sheet material via the sheet material conveying device 2. Since the film material is laminated onto the sheet material, the film feeding roller 601, pulled forward by the laminating device 3 and the sheet material conveying device 2, continuously feeds out the film. Under the action of the laminating mechanism, the two films gradually adhere and laminate onto the sheet material. Finally, the laminated sheet material is fed into the shearing device 4, which cuts the film material into individual sheets, which fall to the collection position. During the shearing process, the cutting detection device 5 detects the sheet material. If the sheet material is not completely cut and becomes entangled, the cutting detection device 5 sends a detection signal to the control device, causing the control device to stop all devices from operating. This double-sided feeding, laminating, and shearing integrated machine can double-sidedly laminate and cut the sheet material into individual sheets, and can detect whether the sheet material is completely cut, avoiding entanglement and effectively ensuring the quality of the sheet material.

[0027] The aforementioned control device can be a computer, a microcontroller, a programmable controller, etc.; the aforementioned sheet material conveying device 2 can be multiple conveying rollers and a drive mechanism that can drive the conveying rollers to rotate; the aforementioned laminating device 3 can be two parallel composite rollers and a drive mechanism that can drive the composite rollers to rotate, with a gap between the two composite rollers for the sheet material to pass through; the aforementioned shearing device 4 can be a cutter and a drive mechanism that drives the cutter.

[0028] The shearing detection device 5 includes a displacement sensor 501 and a roller 502. The cavity of the displacement sensor 501 is mounted on the frame 1, and the moving end of the displacement sensor 501 faces downward. The roller 502 is rotatably disposed at the lower end of the moving end of the displacement sensor 501, and the position of the roller 502 corresponds to that of the laminating device 3. The laminated sheet material is fed to the shearing device 4 from the rear of the self-coating device 3. During the conveying process, the roller 502 rolls and contacts the surface of the sheet material. If the shearing device 4 does not completely cut the sheet material, the uncut sheet material will pull on the sheet material as it falls, causing the sheet material to lift up. At this time, the lifted sheet material will push up the moving end of the displacement sensor 501 through the roller 502, causing the moving end to move a large distance. The displacement sensor 501 sends the detected displacement distance signal to the control device. If the displacement distance signal received by the control device exceeds the preset reasonable displacement distance (the sheet material will also slightly lift the moving end of the displacement sensor 501 during normal conveying, so the control device has a preset reasonable displacement distance. Within the reasonable displacement distance, the control device judges that there is no uncut situation), the control device judges that the sheet material is not completely cut, and at this time the control device controls the equipment to stop.

[0029] The film material conveying device 6 includes a film feeding roller 601 and a rotation counting mechanism 602. The film feeding roller 601 is rotatably mounted on the frame 1. The rotation counting mechanism 602 includes a code disk 6021 and a proximity switch 6022. The code disk 6021 is coaxially fixedly connected to the corresponding film feeding roller 601. The code disk 6021 is provided with a notch 60211. The proximity switch 6022 is mounted on the frame 1, and the sensing area of ​​the proximity switch 6022 is aligned with the code disk 6021. The signal output terminal of the proximity switch 6022 is electrically connected to the corresponding signal input terminal of the control device. During the lamination process, the two film feeding rollers 601 rotate at the same speed. Therefore, the detection time of the corresponding proximity switch 6022 will be the same for each revolution of the two film feeding rollers 601. When the detection time of the two proximity switches 6022 deviates, it indicates that there is a difference in the rotation speed of the two film feeding rollers 601. The film material on the slower film feeding roller 601 is in an overstretched state, and continuing to feed the film will cause it to break. Therefore, when the control device detects a time difference in the detection signals of the two proximity switches 6022, it can control the traction lamination mechanism to stop working, allowing the staff to promptly inspect and adjust the film feeding rollers 601. This setting further ensures the lamination quality of the sheet material.

[0030] The film conveying device 6 also includes a film feeding roller fine-tuning mechanism 603. The film feeding roller 601 is rotatably mounted on the frame 1 via the corresponding film feeding roller fine-tuning mechanism 603. When the speed of the film feeding roller 601 deviates, the main reason is that the position of the film feeding roller 601 deviates. Therefore, the film feeding roller 601 can be finely adjusted by the film feeding roller fine-tuning mechanism 603 to return the film feeding roller 601 to the normal film feeding position and continue feeding, ensuring that the fed film material is aligned with the sheet material.

[0031] The film feeding roller fine-tuning mechanism 603 includes a mounting plate 6031, a mounting shaft 6032, and two guide adjustment components 6033. The mounting shaft 6032 is rotatably mounted on the mounting plate 6031, and the film feeding roller 601 is connected to the corresponding mounting shaft 6032. The mounting plate 6031 is movable inward and outward on the frame 1 via the guide adjustment components 6033. During adjustment, the mounting plate 6031 is moved and adjusted by the corresponding guide adjustment components 6033, thereby adjusting the position of the film feeding roller 601.

[0032] The guide adjustment assembly 6033 includes an adjustment rod 60331 and a compression spring 60332. The mounting plate 6031 has two through holes, and the frame 1 has two screw holes corresponding to the positions of the through holes. The number of through holes is the same as the number of guide adjustment assemblies 60333, and they correspond one-to-one. The outer end of the adjustment rod 60331 is provided with a stop block 603311, and the inner end of the adjustment rod 60331 is provided with a thread 603312 that matches the screw hole. The adjustment rod 60331 can move inward and outward through the through hole, and the inner end of the adjustment rod 60331 is connected to the screw hole thread 603312. The compression spring 60332 is sleeved on the adjustment rod 60331, and the outer end of the compression spring 60332 is in close contact with the stop block 603311 of the adjustment rod 60331. The inner end of the compression spring 60332 is connected to the mounting plate 6031. During adjustment, by rotating the adjusting rod 60331, the stop block 603311 on the adjusting rod 60331 moves closer to or further away from the frame 1. At this time, the mounting plate 6031 moves closer to or further away from the frame 1 under the action of the compression spring 60332, thereby driving the film feeding roller 601 to move accordingly. The adjusting rod 60331 can be a screw, wherein the head of the screw constitutes the stop block 603311.

[0033] The guide adjustment assembly 6033 also includes a guide sleeve 60333, which is fixedly installed in the through hole. The adjusting rod 60331 moves inward and outward through the guide sleeve 60333. During adjustment, the adjusting rod 60331 can move along the guide sleeve 60333.

[0034] The inner end face of the mounting shaft 6032 is provided with a limiting protrusion 60321, and the end face of the film feeding roller 601 is provided with a limiting groove 6011 that matches the limiting protrusion 60321. When the film feeding roller 601 is connected to the mounting shaft 6032, the limiting protrusion 60321 can be inserted into the limiting groove 6011, thereby fixing the position of the film feeding roller 601.
