Description

Technical Field

[0001] This invention belongs to the technical field of cladding cutting equipment, and relates to a one-to-many cladding cutting production line. Background Technology

[0002] Laminating is a process in which paper and plastic are bonded together under pressure using rubber rollers to form a paper-plastic composite product. It is commonly used in the production of paper, boards, and laminates. Traditional laminating processes use laminating machines, grooving machines, and cutting machines. Moreover, to meet the diverse needs of users, the cutting of boards has changed from traditional fixed shapes to personalized irregular shapes. Ordinary cutting machines cannot meet the cutting requirements of irregular shapes and patterns on boards.

[0003] In the prior art, Chinese patent with publication number CN121468690A discloses a machine vision-based irregular shape cutting device that integrates machine vision, multi-axis linkage and intelligent adsorption functions; it can cut irregular shapes and patterns; however, in order to improve production efficiency, two cutting devices are set up side by side to perform cutting operations simultaneously. For the feeding of the two cutting devices, each is connected to a laminating machine or feeding device, or the feeding is done manually, which increases equipment investment, increases floor space, or increases labor intensity.

[0004] Therefore, in order to solve the above-mentioned technical problems, there is an urgent need for a one-to-many cladding cutting production line that can feed cladding to the cutting equipment. Summary of the Invention

[0005] This invention proposes a one-to-many sheet covering cutting production line, which effectively solves the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a one-to-many cladding cutting production line, including a feeding device and a cladding device connected to the feeding port of the feeding device, the discharge port of the cladding device being connected to a distributing device, the distributing device having two feeding ports at one end away from the cladding device, and a cutting device being provided at each feeding port.

[0007] The feeding device includes a feeding platform and multiple parallel conveying rollers arranged on the feeding platform. The feeding platform can receive the covering plate from the discharge port of the covering plate device and convey the covering plate to one end of the feeding platform close to the cutting device through the conveying rollers.

[0008] It also includes a transverse transfer platform mirrored on both sides of the loading platform. The transverse transfer platform is provided with multiple support rollers parallel to the conveying rollers. The transverse transfer platform is provided with a distribution mechanism that can transfer the cover plate on the loading platform to the transverse transfer platform.

[0009] The feeding port is located at one end of the transverse platform away from the covering plate device, and each feeding port is equipped with a conveying mechanism for conveying the covering plate on the transverse platform out of the feeding port for feeding the cutting device.

[0010] Furthermore, the dispensing mechanism includes a mobile platform, with rollers provided on the bottom surface of the mobile platform. A connecting beam for the rollers to reciprocate is spanned between the transverse platform and the feeding platform. The mobile platform is connected to a second drive source provided on the transverse platform. A follower structure capable of driving the cover plate to move is provided at one end of the mobile platform in the direction of movement.

[0011] Furthermore, the follow-up structure includes a first cylinder disposed on the moving platform, the axis of the first cylinder being perpendicular to the upper side of the moving platform, and the telescopic end of the first cylinder being able to extend above the cover plate.

[0012] Furthermore, the second drive source includes a second servo motor and a second transmission structure connected to the second servo motor, the second transmission structure being connected to the mobile platform.

[0013] Furthermore, the conveying roller is connected to a first drive source; the first drive source includes a first servo motor disposed in the middle of the loading platform, a rotating long shaft rotatably connected to the loading platform, and a first transmission structure connected between the first servo motor and the rotating long shaft, wherein a transmission belt is connected between the rotating long shaft and each conveying roller.

[0014] Furthermore, the conveying mechanism includes a frame and a drive roller and a driven roller rotatably mounted on the frame. The drive roller is connected to a third drive source mounted on the frame. The driven roller is mounted above the drive roller and can be adjusted up and down. The output side of the drive roller is provided with a support structure that can support the conveyed cover plate.

[0015] Furthermore, the support structure includes a support plate disposed on the output side of the drive roller, the support plate being hinged to the frame on the side near the frame, and a pull rope that can be connected to the frame is hooked in the middle of the support plate.

[0016] Furthermore, both ends of the driven roller are provided with a second cylinder connected to the frame, and the telescopic end of the second cylinder is connected to a mounting plate. Both ends of the driven roller are rotatably connected to the mounting plate.

[0017] Furthermore, the support structure includes a first frame that can extend from the output side of the drive roller to the outside of the frame, and a support member is provided at the end of the first frame away from the frame, and the support member has an inclined connecting surface on the side facing the frame.

[0018] Furthermore, a stop plate is provided at the end of the feeding platform opposite to the covering plate device.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In this invention, the feeding platform receives the covering plates output from the outlet of the covering plate device, and the distribution mechanism can transfer the covering plates from the feeding platform to the transverse platform. The conveying mechanism on different transverse platforms feeds different cutting devices, which satisfies the transverse distribution of the covering plates and realizes the conveying of covering plates to two cutting devices set up side by side. This reduces the use of the covering plate device or the feeding device, reduces the workload of workers, and improves production efficiency. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figures 1 to 3 As shown, this invention proposes a one-to-many veneer cutting production line, including a feeding device 23 and a veneer device 24 connected to the feeding port of the feeding device 23. A distribution device is connected to the discharge port of the veneer device 24. The distribution device has two feeding ports at one end away from the veneer device 24, and each feeding port is equipped with a cutting device 25. The veneer device 24 has a cutting mechanism and a mounting mechanism. The feeding device 23 continuously feeds veneer material to the mounting mechanism, which presses the plastic film onto the veneer. The cutting mechanism cuts the mounted veneer into veneers of the same size. After being conveyed out of the cutting mechanism, the veneers are received by the distribution device and then distributed... The feeding device distributes the board to different cutting devices 25 to cut the irregular shapes on the board. In this embodiment, the feeding device 23 and the covering device 24 are both existing technologies. For example, the specific structure disclosed in a multi-functional mounting and cutting integrated machine with publication number CN114055544B can be used to complete the feeding, mounting and cutting actions, preparing for the feeding device to distribute the board and the cutting device 25 to cut the irregular shapes. Furthermore, the cutting device 25 is also existing technology. For example, the technical solution disclosed in a machine vision-based irregular shape cutting device with publication number CN121468690A can be used to cut the covering of the irregular shape pattern.

[0038] In this embodiment, the dispensing device includes a feeding platform 1 and a plurality of parallel conveying rollers 2 disposed on the feeding platform 1; it also includes a transverse platform 4 mirror-distributed on both sides of the feeding platform 1, a plurality of support rollers 5 parallel to the conveying rollers 2 disposed on the transverse platform 4, and a dispensing mechanism 6 disposed on the transverse platform 4 capable of transferring the cover plate on the feeding platform 1 to the transverse platform 4. The feeding port is disposed at one end of the transverse platform 4 away from the cover plate device 24, and each feeding port is provided with a conveying mechanism 7, which can transfer the cover plate on the transverse platform 4 out of the transverse platform 4 and feed it to the cutting device 25.

[0039] Among them, such as Figure 2 As shown, both the loading platform 1 and the transverse platform 4 are steel frames welded from shaped steel or steel pipes. Supports or bearing seats are bolted to both sides of the loading platform 1, and the two ends of the conveying roller 2 are rotatably connected to the supports or bearing seats. Support plates are welded or bolted to both sides of the transverse platform 4, and the ends of the support roller 5 are connected to the support plates by screws. In this embodiment, the ends of the conveying roller 2 and the support roller 5 are aligned and on the same horizontal plane. Multiple parallel connecting beams 8 are provided between the loading platform 1 and the transverse platform 4, and the distributing mechanism 6 can move along the connecting beams 8.

[0040] In this embodiment, as Figure 2 , Figure 4 , Figure 10 As shown, the conveyor roller 2 is connected to a first drive source 3. The first drive source 3 includes a first servo motor disposed in the middle of the loading platform 1, a rotating long shaft 301 rotatably connected to the loading platform 1, and a first transmission structure 302 connecting the first servo motor and the rotating long shaft 301. A transmission belt 303 is connected between the rotating long shaft 301 and each conveyor roller 2. The two ends of the transmission belt 303 are respectively sleeved on the conveyor roller 2 and the rotating long shaft 301, and the power is transmitted through friction. Specifically, multiple [unclear text - possibly a continuation of the previous sentence] are fitted on the rotating long shaft 301. A bearing and bearing housing are mounted on the loading platform 1. The transmission belt 303 is a rubber belt. The first transmission structure 302 includes a drive pulley mounted on the output shaft of the first servo motor, a driven pulley keyed to the rotating long shaft 301, and a synchronous belt connecting the drive pulley and the driven pulley. The first servo motor drives the rotating long shaft 301 to rotate through the first transmission structure 302. The rotating long shaft 301 drives all the conveying rollers 2 to rotate through the transmission belt 303, thereby realizing the conveying of the cover plate on the loading platform 1.

[0041] In this embodiment, as Figures 5 to 7As shown, the dispensing mechanism 6 includes a moving platform 601, with rollers 602 mounted on its bottom surface. The rollers 602 enable the moving platform 601 to reciprocate on the transverse platform 4. The moving platform 601 is connected to a second drive source 9 mounted on the transverse platform 4. One or both ends of the moving platform 601 are equipped with a follower structure capable of moving the cover plate. The second drive source 9 includes a second servo motor and a second transmission structure connected to the second servo motor. The second transmission structure uses a synchronous pulley and a synchronous belt structure. The synchronous pulley is mounted on the transverse platform 4. The synchronous belt spans across the transverse platform 4 on both sides of the platform 4. The output shaft of the second servo motor is connected to a drive gear, and the drive pulley is coaxially connected to a driven gear. The driven gear and the drive gear can mesh to drive the rotation of the synchronous pulley. The moving platform 601 is connected to a clamping plate structure 26 that can clamp the synchronous belt. The clamping plate structure 26 consists of two parallel plates located on the upper and lower sides of the synchronous belt. Bolt holes are opened on the plates, and the two plates are fixed to the moving platform 601 by bolt and nut structure, thereby transmitting power to the moving platform 601.

[0042] Specifically, the mobile platform 601 includes longitudinal beams and multiple crossbeams vertically connected to the longitudinal beams. Both the longitudinal beams and crossbeams can be made of square steel pipes or steel plates bent into rectangular box shapes. The crossbeams can be aligned parallel at equal intervals, and one end of the crossbeam is bolted to the longitudinal beam. At both ends of the crossbeams, an inverted U-shaped frame is fixed with screws. Rollers 602 are rotatably connected to the opening of the U-shaped frame. The rollers 602 can be solid flat wheels or channel steel wheels. The platform can move as a whole between the loading platform 1 and the transverse moving platform 4 on the connecting beam 8 via the rollers 602.

[0043] Specifically, a vertical plate is connected to the side of the crossbeam, and a slider is fixed to the lower end of the vertical plate by screws. A slide rail is provided between the transverse platform 4 or the loading platform 1. The slide rail is connected to the steel frame of the transverse platform 4 and / or the loading platform 1 by screws. The slider slides onto the slide rail. The groove on the slider can be a dovetail groove or a T-groove. The slide rail and slider can guide the movement of the moving platform 601, prevent the roller 602 from deviating from or detaching from the connecting beam 8, and make the operation more stable.

[0044] In this embodiment, as Figure 3 , Figure 5As shown, the follow-up structure includes a first cylinder 10 disposed on the moving platform 601. The axis of the first cylinder 10 is perpendicular to the upper side of the moving platform 601, and the telescopic end of the first cylinder 10 can extend to the top of the cover plate. When the moving platform 601 passes under the cover plate, the first cylinder 10 passes under the cover plate to the other side of the cover plate, and the telescopic end of the first cylinder 10 can extend to the top of the cover plate. When the moving platform 601 returns to its original position, the telescopic end of the first cylinder 10 can stop and push the edge of the cover plate. As the moving platform 601 moves laterally on the loading platform 1 and the transverse moving platform 4, the follow-up operation of the cover plate is completed.

[0045] In this embodiment, as Figure 8 , Figure 9 As shown, the conveying mechanism 7 includes a frame and a drive roller 701 and a driven roller 702 rotatably mounted on the frame. The drive roller 701 is connected to a third drive source 703 mounted on the frame. The output side of the third drive roller 701 is provided with a support structure that can support the conveyed cover plate. Both ends of the driven roller 702 are provided with a vertical second cylinder 13 connected to the frame. The telescopic end of the second cylinder 13 is connected to a mounting plate 14. Both ends of the driven roller 702 are rotatably connected to the mounting plate 14. The second cylinder 13 can drive the driven roller 702 to move up and down, and can clamp the end edge of the cover plate between the drive roller 701 and the driven roller 702. Under the power provided by the third drive source 703, the clamped cover plate is conveyed. Specifically, the third drive source 703 is a synchronous pulley and synchronous belt structure driven by a servo motor. The synchronous pulley is connected to the output shaft of the servo motor and the end of the drive roller 701. When the servo motor is started, the drive roller 701 can be rotated through the transmission of the synchronous pulley and synchronous belt.

[0046] In this embodiment, the support structure includes a support plate 11 disposed on the output side of the drive roller 701. The support plate 11 is hinged to the frame on the side near the frame, and a pull rope 12 that can be connected to the frame is hooked in the middle of the support plate 11. Screws are connected to both sides of the support plate 11 in the conveying direction of the cover plate. Both ends of the pull rope 12 are tied with lifting rings. Similarly, screws are also connected to the mounting shell of the frame. The lifting rings at both ends of the pull rope 12 are hooked onto the screws. After the support plate 11 is rotated and lowered, the support plate 11 is kept horizontal under the action of the pull rope 12. The cover plate output from the output side of the drive roller 701 is supported to prevent the end edge of the cover plate from tilting downward due to its own weight, and to ensure that the cover plate can smoothly enter the feed port of the cutting device.

[0047] In this embodiment, the transverse platform 4 and the distributing mechanism 6 can be arranged in multiple groups along the conveying direction of the feeding platform 1, thereby accommodating cover plates of different lengths and increasing the range of applications.

[0048] In this embodiment, a stop plate 15 is provided at one end of the feeding platform 1 opposite to the covering plate device 24; the two ends of the stop plate 15 are connected to upright plates by screws, and the upright plates are connected to the steel frame of the feeding platform 1 by screws; the stop plate 15 can stop the covering plate on the feeding platform 1, prevent the covering plate from being transported out of the feeding platform 1, and also ensure that when the covering plate is transferred from the feeding platform 1 to the transverse platform 4, the end edge of the covering plate is located between the drive roller 701 and the driven roller 702.

[0049] When using the above technical solution:

[0050] First, the feeding device 23 continuously feeds the sheet material to the covering device 24. The covering device 24 can press the plastic film onto the sheet and cut it into covered products of the same size. The covered sheets output by the covering device 24 are received by the feeding platform 1 in the distribution device.

[0051] Next, the first drive source 3 is started, which drives multiple conveyor rollers 2 to transport the entire cover plate onto the loading platform 1, and the end edges of the cover plate are stopped by the stop plate 15.

[0052] Next, the feeding mechanism 6 on one side of the feeding platform 1, driven by the second drive source 9, drives the moving platform 601 to pass under the cover plate, and causes the first cylinder 10 to move to the other side of the cover plate. The first cylinder 10 is controlled to extend its telescopic end to the top of the cover plate. At this time, the second drive source 9 drives the moving platform 601 to move in the opposite direction. The telescopic end of the first cylinder 10 moves the cover plate, so that the cover plate is transferred to the transverse platform 4 along with the moving platform 601, and the end edge of the cover plate is located between the drive roller 701 and the driven roller 702 in the conveying mechanism 7.

[0053] Finally, the second cylinder 13 drives the driven roller 702 to move downward, so that the driven roller 702 clamps the end edge of the cover plate onto the drive roller 701, and starts the third drive source 703 in the conveying mechanism 7. The third drive source 703 drives the drive roller 701 to rotate, thereby causing the cover plate to be transferred out of the transverse platform 4 and fed to the corresponding cutting device 25. The cutting device 25 cuts the irregular shape pattern on the cover plate to form the final product.

[0054] Example 2

[0055] The difference compared to Example 1 is as follows: Figure 11As shown, the second drive source 9 also includes a mounting box 21. The mounting box 21 is rectangular and assembled from plates, with only side panels and no top or bottom panels. A synchronous pulley is rotatably mounted in the mounting box 21. Auxiliary wheels 22 are rotatably connected to the mounting box 21 at both ends of the synchronous pulley. The synchronous belt passes over the auxiliary wheels 22 and under the synchronous pulley inside the mounting box 21. The synchronous pulley inside the mounting box 21 is coaxially connected to the drive gear. The second servo motor is bolted to the steel frame of the transverse platform 4. The two auxiliary wheels 22 enable the synchronous belt and the synchronous pulley inside the mounting box 21 to have a reliable engagement angle, ensuring stable power transmission. Preferably, if setting multiple crossbeams results in a wider mobile platform 601, multiple sets of synchronous pulleys and synchronous belt structures can be set. The active synchronous pulleys in the multiple sets of synchronous pulleys and synchronous belt structures are coaxially connected by a long shaft. Therefore, after cooperating with the clamping plate structure 26, multiple uniform force application points are formed on the mobile platform 601, maintaining the stability of the mobile platform 601 during movement.

[0056] Example 3

[0057] The difference compared to the above embodiments is as follows: Figure 12 , Figure 13 As shown, the support structure includes a first frame 16 that can extend from the output side of the drive roller 701 to the outside of the frame. A support member 17 is provided at the end of the first frame 16 away from the frame, and an inclined connecting surface 18 is provided on the side of the support member 17 facing the frame.

[0058] The first frame 16 is welded into a quadrilateral shape from multiple steel sections or pipes. Two columns are welded to the end of the first frame 16 away from the machine frame. The support member 17 is stamped from sheet metal into a trapezoidal shape. The two side plates of the support member 17 are installed on the upper end of the columns with screws. The upper side plate of the support member 17 is horizontal, while the inclined side plate on the support member 17 is the connecting surface 18. The support member 17 is positioned in the middle of the machine frame and the cutting device. The support member 17 supports the conveyed cover plate, preventing it from tilting downwards and allowing it to smoothly enter the feed port of the cutting device. The inclined connecting surface 18 guides the end edge of the cover plate, allowing it to slide along the connecting surface 18 to the top of the support member 17 during the conveying process, thus supporting the cover plate.

[0059] In this embodiment, a slider is bolted to the lower side of the first frame 16, and a slide rail that cooperates with the slider is provided below the first frame 16. The slide rail is connected to the second frame 19. By cooperating with the slider and the slide rail, the distance between the support member 17 and the frame can be adjusted, making it suitable for gaps of different widths. For cover plates of different materials, the length of the output side of the drive roller 701 is different, and the downward tilt position is also different. The position of the support member 17 can be adaptively adjusted by the slider and the slide rail, making it more widely applicable. Specifically, the second frame 19 is made of steel pipe or profile, and the slide rail is bolted to the upper surface of the second frame 19.

[0060] In this embodiment, a stop cylinder 20 is provided at one end of the slide rail, and a frame is integrally formed or welded to the end of the second frame 19. The stop cylinder 20 is installed on the frame by bolts. Multiple stop holes are opened on the lower side of the first frame 16, and the stop holes are arranged along the length of the slide rail. The telescopic end of the stop cylinder 20 can be inserted into the stop hole. The second frame 19 can be installed on the steel frame of the transverse platform 4 or the frame of the conveying mechanism 7 by bolts. When the position of the support member 17 is adjusted by the slide rail slider, the telescopic end of the stop cylinder 20 is extended and inserted into the stop hole to limit the position of the first frame 16 and the support member 17, so as to prevent movement during the conveying of the cover plate and improve the reliability of use.

[0061] Furthermore, the support structure in this embodiment can be installed on the feeding end of the feeding platform 1 facing the covering device 24, and the inclined connecting surface 18 on the support member 17 can face the covering device 24 to receive the covering plate discharged from the outlet of the covering device 24, thereby improving the reliability of feeding the feeding platform 1.

[0062] Although the present invention 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 invention should be included within the protection scope of the present invention.
