Description

Technical Field

[0001] This invention patent relates to the field of decorative panel molding, and particularly to a molding feeding system and a molding production line for decorative panels. Background Technology

[0002] Decorative panels are thermosetting laminated plastics made from various special papers that have undergone chemical treatment and are then bonded with high-temperature, high-pressure adhesives. The panels feature various wood grains or patterns, are smooth and glossy, and have vibrant and attractive colors. They also possess excellent physical properties such as high wear resistance, heat resistance, cold resistance, and fire resistance. Decorative panels can be molded to create the desired patterns, textures, and designs.

[0003] In existing molding processes for decorative panels, the blank is first placed on a work platform, and then the work platform and the decorative panel are fed into a molding machine for molding. However, if there is a gap or insufficient support on the work platform below the decorative panel blank during molding, the molding effect of the entire decorative panel blank will be greatly affected, and may even crush the entire decorative panel blank, thus affecting the overall processing quality and efficiency. Therefore, it is necessary to develop a molding system that can ensure stable support under the decorative panel before molding. Summary of the Invention

[0014] The second objective of this invention patent is to provide a molding production line for decorative panels, which can realize rapid feeding, molding and unloading of decorative panels, ensuring high quality and efficiency in the overall processing of decorative panels, and is stable and practical.

[0015] The technical solution to achieve the purpose of this invention patent is as follows: This invention patent includes the above-mentioned decorative panel molding and feeding system, molding machine, and unloading mechanism for unloading the molded decorative panel. The first substrate is transferred to the molding machine for molding by the sequential driving of the first driving member and the second driving member. After molding, it is brought back to the return material mechanism by the driving of the second driving member. The return material mechanism displays the molded decorative panel and resets each piece. Then, the unloading mechanism unloads each decorative panel. The unloading mechanism includes an unloading bracket fixed to one side of the return material bracket, an unloading cylinder fixed on the unloading bracket, a picking bracket rotatably connected to the unloading bracket under the driving of the unloading cylinder, and a vacuum suction plate fixed on the picking bracket. The vacuum suction plate is flipped above the second lifting plate on the return material bracket by the driving of the unloading cylinder and picks up the molded decorative panel on the first substrate.

[0016] This invention patent has the following positive effects: (1) This invention uses a feeding mechanism to feed the decorative panel and a return mechanism to return the decorative panel. During the feeding process, each block on the first substrate supports the decorative panel. The arrangement of each block can meet the support of decorative panels of various shapes and sizes. When the decorative panel on the first substrate passes under the scanning part, each baffle extends under the drive of the second cylinder and moves the magnetic rotating part, rotating the block that does not support the decorative panel from the vertical state to the horizontal state. After the movement is completed, the first substrate is reset again under the drive of the first driving member. After the reset is completed, the first lifting plate lifts the block under the decorative panel, thereby supporting the decorative panel and the decorative panel. The blocks under the decorative panels are inspected to ensure that each position under each decorative panel is fully supported. This effectively avoids the problem of gaps or empty supports under the decorative panels in existing technologies, which can lead to damage or breakage during molding. The support of each block effectively ensures the stability of the bottom support of the decorative panel. After molding, the second lifting plate is driven by the reset cylinder and the magnetic attraction between the second lifting plate and each rotating part to reset each rotated part after being moved. Under the drive of the second driving component, it is transferred to the loading bracket for unloading and loading of the next decorative panel. This ensures the stability of the loading and molding of the decorative panels, as well as the high efficiency of the molding process. The structure is ingenious, convenient and practical.

[0017] (2) This invention further ensures the stability of the decorative panel and the block support by setting an anti-slip pad on the top block. The rotating part rotates through the cooperation of the rotating shaft and the rotating hole, ensuring the smoothness of the rotating part. The diameter of the rotating hole is larger than the diameter of the rotating shaft, thus giving the rotating part sufficient rotation margin and rotation space. At the same time, after the pressing surface is disengaged from the stop surface by the paddle, it is guided by the arc-shaped guide surface and pressed against the pressing slope surface and fixed by the locking part, ensuring the stability of the rotating part after rotation. It will not rotate again due to its own weight, which is convenient and practical.

[0018] (3) The present invention provides a locking groove on the positioning part, a connecting rod in the locking groove, and a compression spring on the connecting rod to drive the locking rod to continuously press against the rotating part, thereby ensuring the stable shaping of the rotating part after rotation, which is convenient and practical.

[0019] (4) By setting a side guide block on the positioning part and setting a side guide groove on the side of the through groove to match the side guide block, the present invention can ensure the smoothness of the assembly block during the lifting process and ensure that the assembly block will not deviate during the lifting process, thus ensuring the stability of the assembly block when lifting, which is safe and convenient.

[0020] (5) By setting a mounting base at the telescopic end of the bottom cylinder and uniformly installing each second cylinder on the mounting base, the present invention effectively ensures the stability of the individual baffle during the process of moving the rotating plate, as well as the flexibility of moving the rotating part, thereby ensuring the precise moving of the rotating part on each block, which is stable and practical.

[0021] (6) The present invention provides multiple mounting slots on the second lifting plate, sets opposing magnetic side plates in the mounting slots, and sets magnetic strips between the magnetic side plates. Through the cooperation of the magnetic side plates and magnetic strips, and the driving of the second lifting plate by the reset cylinder, the molded decorative panel can be lifted and displayed. On the other hand, during the descent of the second lifting plate, the rotating parts after rotation can be rotated and reset. This ensures that the rotating parts on all the panels can be reset at the same time, and also ensures the subsequent use of the first substrate. Even if the first substrate is slightly offset during the reset process, the multiple parallel mounting slots can ensure that all rotating parts can be reset, which is efficient and convenient.

[0022] (7) The present invention provides a plurality of first driving blocks on a first substrate, and the driving screws on each first driving block pass through the threaded holes and extend into the chain gaps on the first conveyor chain, thereby ensuring a rapid connection between the first substrate and the first conveyor chain, as well as a firm connection between the first driving block and the first substrate. It also ensures that the first substrate is transported stably and smoothly under the drive of the first conveyor chain, avoiding relative sliding between the first substrate and the first conveyor chain. This invention achieves a rapid connection between the first substrate and the first conveyor chain, as well as a rapid disengagement of the first substrate from the first conveyor chain when it enters the second or third conveyor chain. The structure is ingenious, stable and practical.

[0023] (8) This invention sets up an upper channel and a lower channel on the return support. The upper channel is responsible for taking out the first substrate from the molding machine, and the lower channel is responsible for conveying the first substrate on the loading support into the molding machine. At the same time, the cooperation of the upper channel and the lower channel can realize the alternating operation of the two first substrates. After the first substrate is taken out from the molding machine, the other first substrate can be sent back into the molding machine. Then, the two first substrates are used to feed, convey and unload the decorative panel in turn. When the upper channel is connected to the discharge port of the loading support, the first conveyor chain can cooperate with the second conveyor chain to convey the first substrate after each rotating part is reset to the loading support. When the lower channel is connected to the discharge port of the loading support, the first conveyor chain can cooperate with the third conveyor chain to convey the first substrate on the loading support into the molding machine. This realizes the cyclic use of the two second substrates, thereby ensuring the high efficiency of the overall feeding and molding. It is efficient and practical.

[0024] (9) The present invention sets the drive bracket to include the connection of the upper and lower brackets arranged in parallel and the rotating bracket. The upper bracket is lifted and lowered by the drive of the lifting cylinder, and drives the return bracket to lift and lower, thereby realizing the rapid switching between the upper channel and the lower channel, which is efficient, stable and practical.

[0025] (10) The present invention sets up a molding production line and sets up a feeding mechanism for feeding. Each vacuum suction hole on the vacuum suction plate is driven by the feeding cylinder to flip the feeding bracket to the top of the first substrate in the upper channel, and the molded decorative board is picked up and fed, which ensures the stability of the decorative board and the efficiency of feeding during the feeding process.

The end is slidably connected to the upper support 51, and a connecting shaft 55 is provided between each rotating support 53. The connecting shaft 55 is arranged parallel to the lower support 52 and is rotatably connected to each first rotating rod 531 and second rotating rod 532. The lifting cylinder 54 rotates on the lower support 52, and the extension end of the lifting cylinder 54 is rotatably connected to the connecting shaft 55.

[0054] This invention also relates to a molding production line for decorative panels, including a molding feeding system for decorative panels, a molding machine 3, and a feeding mechanism for unloading the molded decorative panels. A first substrate 4 is sequentially driven by a first driving member and a second driving member to be transferred into the molding machine 3 for molding. After molding, it is brought back to the return material mechanism 2 by the second driving member. The return material mechanism 2 displays the molded decorative panels and resets each assembly piece 7 before unloading each decorative panel through the feeding mechanism. The feeding mechanism includes a fixed support... The material support 21 includes a material feeding support 61 on one side, a material feeding cylinder 62 fixed on the material feeding support 61, a material taking support 63 rotatably connected to the material feeding support 61 under the drive of the material feeding cylinder 62, and a vacuum suction plate 64 fixed on the material taking support 63. The vacuum suction plate 64 is provided with multiple vacuum suction holes 65. The vacuum suction plate 64 is flipped above the second lifting plate 25 on the return support 21 by the drive of the material taking support 63 by the material feeding cylinder 62, and takes the molded decorative panel by adsorbing the decorative panel through each vacuum suction hole 65.

[0055] The working principle of this invention: In the process of using this invention, each assembly block 7 is first installed on the first substrate 4 through the insertion and engagement with the through slot 41, and the insertion and engagement of each side guide block 75 and the side guide slot 42. Then, the first substrate 4 is placed on the loading bracket 11, and the first conveyor chain 14 on the loading bracket 11 is embedded in the groove 431 of each first drive block 43. At the same time, each drive screw 44 extends into the corresponding chain gap on the first conveyor chain 14. Then, the blank of the decorative panel is placed on the first substrate 4, and the first motor drives the first conveyor chain 14 to start running. The first conveyor chain 14 drives the first substrate 4 to move towards the scanning unit 13. The scanning unit 13 scans the blank of the decorative panel. Each second cylinder 18 controls the extension of each baffle 19 according to the scanning result. While scanning, it moves the rotating part 73 under each piece 7 that does not support the blank of the decorative panel. During the process of rotating each rotating part 73 from the vertical state to the horizontal state, the pressing surface 734 is separated from the stop surface 723 and then pressed against the pressing inclined surface 725 by the guide of the arc-shaped guide surface 724. Then the locking rod 76 presses against the rotating part 73 through the continuous force of the compression spring 77, thereby realizing the shaping of the rotating part 73 after rotation. At this time, the lifting cylinder 54 drives the upper bracket 51 to lift. When it is lifted to the point that the lower channel 2b is connected to the discharge port of the feeding bracket 11, the lifting cylinder 54 stops driving.

[0056] After the rotating parts 73 on all the unsupported decorative panel pieces 7 are repositioned, the first base plate 4, in conjunction with the first conveyor chain 14 and the third conveyor chain 23, returns to the loading bracket 11. Then, the first cylinder 15 drives the first lifting plate 12 to lift. During the lifting process, since all the other rotating parts 73 have rotated to a horizontal state, only the rotating parts 73 on the decorative panel pieces 7 remain in a vertical state. Driven by the first lifting plate 12, each piece 7 below the decorative panel is pushed out. At this time, the operator can... By observation, it can be directly seen whether there are any pieces 7 that have not been ejected, and they can be adjusted. After the adjustment is completed, the first cylinder 15 drives the first lifting plate 12 to descend. Then, the first conveyor chain 14 and the third conveyor chain 23 drive the first substrate 4 in sequence and send it into the molding machine 3. At the same time, the second first substrate 4 is placed into the feeding bracket 11, and the installation method of the first first substrate 4 is connected to the first conveyor chain 14. Each piece 7 is then loaded, and the decorative panel blanks that need to be molded later are placed on this first substrate 4.

[0057] After the decorative panel on the first substrate 4 in the molding machine 3 is molded, the lifting cylinder 54 drives the return support 21 to descend by driving the drive bracket 5. The descent stops when the upper channel 2a connects with the discharge port of the molding machine 3. The second conveyor chain 22, driven by the second motor, picks up the first substrate 4 in the molding machine 3. After being picked up to the upper channel 2a, the reset cylinder 24 drives the second lifting plate 25 to begin lifting, pushing out each of the supporting blocks 7 of the decorative panel and displaying the molded decorative panel. After the display is complete, the reset cylinder 24 drives the second lifting plate 25 to begin lifting. As the second lifting plate 25 descends, the magnetic side plates 26 and the magnetic absorbing pieces 731 on the rotating part 73 magnetically engage during the descent, causing the rotating parts 73 to rotate from a horizontal state to a vertical state. After the rotating parts 73 are reset, the vacuum suction plate 64 is driven by the unloading cylinder 62 to flip the material picking bracket 63 onto the first substrate 4 and adsorbs and picks up the decorative panel through the adsorption of the vacuum suction holes 65. After adsorbing the decorative panel, the vacuum suction plate 64 is driven by the unloading cylinder 62 to reset the material picking bracket 63, and then the operator can remove the decorative panel.

[0058] After the decorative panel on the first substrate 4 in the upper channel 2a is removed, the lifting cylinder 54 drives the drive bracket 5 to raise the lower channel 2b to connect with the outlet of the loading bracket 11. Then, the second first substrate 4 undergoes the aforementioned scanning, prying, resetting, and display. The second first substrate 4 is then sequentially conveyed into the molding machine 3 along the first conveyor chain 14 and the second conveyor chain 22 for molding. The lifting cylinder 54 then drives the drive bracket 5 to lower the upper channel 2a and the first first substrate 4 on the upper channel 2a to connect with the outlet of the loading bracket 11. The first first substrate 4 is then conveyed back to the loading bracket 11 for the placement of the decorative panel blank. Meanwhile, the empty... The upper channel 2a waits for the output of the second first substrate 4 in the molding machine 3. After receiving the second first substrate 4 in the molding machine 3, it performs display, resetting of the assembly 7, and unloading. This process is repeated, with the two first substrates 4 cycling through loading, scanning, displaying, molding, and unloading of the decorative panel blank. On the one hand, this effectively solves the problem in the prior art where the decorative panel blank is damaged due to uneven stress during molding caused by the lack of support or gaps at the bottom. On the other hand, the entire production line also ensures the overall processing efficiency and quality of the decorative panel. The cyclical use of the two first substrates 4 improves the overall molding efficiency and has good adjustability and applicability, making it highly efficient and convenient.
