Description

Technical Field

[0001] The present invention relates to the technical field of double veneer panels, and more specifically, to an automatic paper suction and turning mechanism for double veneer panels and a working method thereof. Background Art

[0002] Double-sided veneer is a kind of board with special treatment on the surface of the base material. Both sides of the board are usually affixed with the same or different decorative papers or films to achieve beautiful and practical effects. This kind of board is used in the production of panel furniture such as furniture, cabinets, wardrobes, as well as wall and ceiling decoration in interior decoration.

[0003] When processing double-sided veneer panels, the face paper is usually flipped manually so that the back of the face paper faces upward, and then the plain board is covered on the face paper with the back facing upward, and then a layer of face paper with the front facing upward is covered on the top of the plain board. After the operation is completed, the plain board and the face paper are sent to the processing equipment for compounding, or the face paper is laminated by electric flipping, that is, the face paper is flipped on the equipment and the front and back of the face paper are adjusted. However, the electric flipping method cannot be used for larger face paper. When one end is flipped, the other end will sag and cannot be flipped, or when the adsorbed end is pulled and moved, the face paper moves as a whole and still cannot be flipped. Therefore, the staff improved the existing method and added a toggle mechanism at the paper flipping position to achieve the purpose of completely flipping the face paper.

[0004] However, double-sided veneer panels require the facing paper to be transferred twice. When laminating thinner plain panels or special-shaped plain panels, thin plain panels and special-shaped plain panels will bend and warp. When the flipped facing paper is laid and the plain panel is covered, the plain panel and the bottom facing paper cannot be completely in contact. In this state, covering another layer of facing paper still cannot fit completely, and may even offset. When laminating, the facing paper and the plain panel will not be able to be completely covered. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide an automatic paper suction and turning mechanism for a double veneer panel and a working method thereof.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic paper suction and turning mechanism for a double veneer panel, comprising an electric lifting work platform, a paper turning assembly arranged on one side of the electric lifting work platform, the paper turning assembly comprising a grabbing mechanism arranged behind the electric lifting work platform and an auxiliary mechanism arranged in front of the electric lifting work platform, the grabbing mechanism is suitable for sucking and turning over the facing paper, the auxiliary mechanism is suitable for limiting and guiding the turned facing paper, the auxiliary mechanism comprises a vertical plate arranged in front of the electric lifting work platform, an auxiliary motor installed above the front surface of the vertical plate, an L-shaped plate arranged above the rear surface of the vertical plate, and a first roller and a second roller connected to the side wall of the L-shaped plate, and the output end of the auxiliary motor passes through the vertical plate and is connected to the side wall of the L-shaped plate.

[0007] A feeding assembly and a transfer assembly installed on the top of the feeding assembly are arranged on one side of the electric lifting workbench. The transfer assembly is suitable for transferring the facing paper, and the feeding assembly is suitable for placing and conveying the transferred facing paper.

[0008] A sorting assembly and a positioning assembly are installed on the top of the feeding assembly. The positioning assembly is suitable for supporting and positioning the facing paper, and the sorting assembly is suitable for flattening the facing paper. The sorting assembly includes a sorting frame installed on the top of the feeding assembly and two sorting cylinders hinged to the side walls of the sorting frame. A tube body is rotatably connected between the ends of the piston rods of the two sorting cylinders.

[0009] The positioning assembly includes a shell installed on the top of the transfer assembly, and four positioning grooves are opened at the four corners of the top of the shell. A positioning block is slidably connected inside each of the positioning grooves, and the positioning blocks are provided with protrusions toward the middle of the shell.

[0010] The present invention is further configured as follows: the grabbing mechanism includes a bracket arranged behind the electric lifting work platform, the bracket is arranged along the extension direction of the electric lifting work platform, a first electric guide rail is installed on the top of the bracket, a support frame is slidably connected to the top of the first electric guide rail, a flipping rod is horizontally arranged on the side of the support frame facing the electric lifting work platform, and a plurality of paper flipping suction cups are equidistantly installed on the bottom of the flipping rod.

[0011] The present invention is further configured as follows: a lifting cylinder is installed on the top of the support frame, the piston rod of the lifting cylinder extends to the interior of the support frame and is installed with a connecting frame, a rotating cylinder is installed on the side of the connecting frame away from the flip rod, and the output end of the rotating cylinder is connected to one end of the flip rod.

[0012] By adopting the above technical solution, when the paper turning suction cup needs to absorb the facial paper, the connecting frame and the flipping rod are pushed downward by the lifting cylinder, so that the paper turning suction cup can be contacted and squeezed with the facial paper. When the lifting cylinder contracts, the facial paper can be lifted. When the facial paper needs to be flipped, one end of the facial paper is first lifted, and then the flipping rod is driven to rotate 180 degrees by the rotating cylinder to flip the facial paper. This method can achieve the purpose of adjusting the orientation of the facial paper before use, which is convenient for the subsequent double-sided pasting of the plain board.

[0013] When the end of the tissue paper is flipped, it is between the first roller and the second roller. After the tissue paper is flipped, the first roller is wrapped by the tissue paper. When the end of the tissue paper is adsorbed and pulled, the auxiliary motor drives the L-shaped plate to swing downward, causing the first roller and the second roller to squeeze and limit the tissue paper, preventing the other end of the tissue paper from moving synchronously and affecting the flipping effect.

[0014] The present invention is further configured as follows: the feeding assembly includes a placing table arranged on one side of the electric lifting workbench, a through groove is opened on the table top of the placing table, a feeding electric slide rail is horizontally installed on the side wall of the through groove, a feeding plate is slidably connected to the side wall of the feeding electric slide rail, and the positioning assembly is installed on the top of the feeding plate.

[0015] The present invention is further configured as follows: the transferring assembly includes a transferring electric guide rail installed on the top of the placing table and a transferring frame slidably connected to the top of the transferring electric guide rail, an adjusting cylinder is installed on the side wall of the transferring frame, the piston rod end of the adjusting cylinder is connected to a supporting frame, the side wall of the supporting frame is hinged with a swing frame, and a plurality of transferring suction cups are equidistantly installed at the bottom of the swing frame.

[0016] The present invention is further configured as follows: two groups of limit blocks are installed on the side walls of the transfer rack, two limit rods are symmetrically installed on the top of the carrier rack, the two limit rods are arranged corresponding to the two groups of limit blocks, and the limit rods are passed through the interior of the corresponding group of limit blocks, and a driving cylinder is installed vertically downward on the top of the carrier rack, and the piston rod end of the driving cylinder is hinged to the top of the transfer suction cup.

[0017] By adopting the above technical scheme, the feeding electric slide rail drives the feeding plate to slide horizontally inside the through groove, that is, the flipped facial paper is transferred to the top of the feeding plate through the transfer assembly, and the staff covers the surface of the facial paper transferred for the first time with the plain plate, and then the transfer assembly transfers the unflipped facial paper to the plain plate. This state forms a pre-compounded state of the plain plate and the facial paper, and the plain plate and the facial paper are sent to the processing equipment position for compounding through the feeding plate to achieve the purpose of processing double-sided decorative panels.

[0018] When the transfer electric guide rail drives the transfer frame to the top of the electric lifting workbench, the top of the tissue paper pile is completely turned over and overlapped with the stacked tissue paper pile again. The tissue paper is in a reverse side facing up state, and the adjusting cylinder is used to drive the supporting frame, the swing frame and the transfer suction cup to move downward as a whole, so that the transfer suction cup contacts the tissue paper, and then the driving cylinder pushes the swing frame to swing downward, so that the transfer suction cup is squeezed and adsorbs the top surface of one end of the tissue paper close to the feeding assembly. After the tissue paper is adsorbed, the swing frame returns to a horizontal state, and the supporting frame moves up and reset as a whole. The transfer electric guide rail drives the transfer frame and the various components connected to the transfer frame in sequence to synchronously move to the top of the feeding assembly, and then the transfer suction cup releases the tissue paper, and then the staff covers the surface of this tissue paper with a blank board, and then uses the transfer assembly to transfer the unturned tissue paper to the surface of the blank board again. After the tissue paper and the blank board are stacked, the feeding assembly is used to feed the material for processing.

[0019] The present invention is further configured as follows: the sorting component also includes two rings that are sleeved on the outer wall of the tube body and symmetrically arranged, a spring is connected between the opposite sides of the two rings and the outer wall of the tube body, the outer wall of the tube body is symmetrically provided with two slide grooves, the two slide grooves are arranged corresponding to the two rings, a guide block is connected to the inner wall of each ring, the guide block on the inner wall of the ring is slidably connected to the inside of the corresponding slide groove, two guide cylinders are installed inside the tube body, the two guide cylinders are arranged corresponding to the two rings, and the piston rods of the guide cylinders are connected to the side walls of the corresponding guide blocks.

[0020] By adopting the above technical scheme, after the face paper after the flipping operation is laid on the top of the shell, the finishing cylinder is used to drive the tube body to move, and the tube body rolls evenly on the face paper and the top of the shell, effectively flattens the face paper and eliminates uneven areas. This operation not only improves the flatness of the face paper, but also facilitates subsequent processing operations. The guide cylinder is used to push the corresponding guide block to slide inside the corresponding slide groove, causing the ring to slide on the outer wall of the tube body, and the two groups of rings squeeze the side wall of the blank board, so that during the flattening process of the top face paper and the blank board, the ring is used to assist in positioning the bottom face paper, and at the same time, the position of the blank board is clamped and positioned. The tube body and the ring cooperate to squeeze the fitting position between the blank board and the face paper, and the position of the blank board is adjusted again to ensure that there is no uncovered part between the blank board and the bottom face paper.

[0021] The present invention is further configured as follows: a fixed plate is installed inside the shell, a positioning electric guide rail is installed on the top of the fixed plate, two sliders are slidably connected to the top of the positioning electric guide rail, each of the sliders is arranged corresponding to two of the positioning blocks, and the positioning blocks are rotatably connected to the side walls of the corresponding sliders.

[0022] The present invention is further configured as follows: two positioning cylinders are hingedly installed on the top of each slider, and rotating rods are connected to the side walls of the two positioning blocks corresponding to the slider, and the piston rods of the two positioning cylinders respectively correspond to the rotating rods of the side walls of the two positioning blocks and are rotatably connected.

[0023] By adopting the above technical solution, after the plain board and the facial paper are placed on the top of the shell, they are flattened by rolling the tube body. During the flattening process, the tube body first passes through two of the positioning blocks, and these two positioning blocks swing to a horizontal state, while the other two positioning blocks remain vertical. The tube body continues to roll, and the horizontal positioning blocks return to a vertical state to clamp the plain board, while the vertical positioning blocks are adjusted to a horizontal state. After the tube body has completely passed, the four positioning blocks are all adjusted to a vertical state, which not only achieves the purpose of adjusting the plain board, but also avoids the plain board from bending again. When the positioning blocks clamp the plain board, the protrusions are used to increase the friction between the positioning blocks and the plain board, that is, after the plain board is flattened, it is positioned by the positioning blocks so that the plain board remains in a horizontal state. The plain board is flattened and the positioning blocks do not block the space above, which is convenient for subsequent processing operations.

[0024] The working method of the automatic paper suction and turning mechanism of the double veneer panel, using the automatic paper suction and turning mechanism of the double veneer panel described above, comprises the following steps:

[0025] S1. The facial paper is stacked on the top of the electric lifting workbench, and the height of the facial paper is adjusted by the electric lifting workbench. When the facial paper is used, the gripping mechanism is first used to adsorb and flip the top surface of the end of the facial paper away from the feeding assembly, and then the gripping mechanism drives the flipped end of the facial paper to move horizontally.

[0026] S2. When the tissue paper is turned over, it is between the first roller and the second roller. After the tissue paper is turned over, the first roller is wrapped by the tissue paper. When the end of the tissue paper is sucked and pulled, the auxiliary motor drives the L-shaped plate to swing downward, causing the first roller and the second roller to squeeze and limit the tissue paper.

[0027] S3. After the facial paper is completely turned over, it overlaps with the stacked facial paper material pile again. Then, the transfer component absorbs the turned facial paper and pulls it to the top of the feeding component and covers it on the top of the positioning component. Then, the finishing component is used to flatten the facial paper.

[0028] S4. The plain board is covered on the flattened surface paper, and then the surface paper on the top of the electric lifting workbench is adsorbed and transferred to the plain board by the transfer component, and this surface paper does not need to be turned over.

[0029] S5. After the placement of the face paper and the plain board is completed, the tube body is used again to roll and flatten them, and then the side wall of the flattened plain board is positioned by the positioning block. After the positioning of the plain board is completed, the feeding assembly is used to send the plain board and the face paper to the processing equipment for compounding.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] (1) By setting a tube body, when the face paper after the flipping operation is laid on the top of the shell, the finishing cylinder is used to drive the tube body to move, and the tube body rolls evenly on the face paper and the top of the shell, effectively flattening the face paper and eliminating uneven areas. This operation not only improves the flatness of the face paper, but also facilitates subsequent processing operations.

[0032] (2) The guide cylinder is used to push the corresponding guide block to slide inside the corresponding slide groove, causing the sleeve ring to slide on the outer wall of the tube body. The two sets of sleeve rings squeeze the side wall of the blank board, so that during the flattening process of the top surface paper and the blank board, the sleeve ring is used to assist in positioning the bottom surface paper, and at the same time, the position of the blank board is clamped and positioned. The tube body and the sleeve ring cooperate to squeeze the fitting position between the blank board and the surface paper, and the position of the blank board is adjusted again to ensure that there is no uncovered part between the blank board and the bottom surface paper.

[0033] (3) By setting the positioning blocks, after the plain board and the face paper are placed on the top of the shell, the tube body is used to roll and flatten them. During the flattening process, the tube body first passes through two of the positioning blocks. These two positioning blocks swing to a horizontal state, and the other two positioning blocks remain vertical. The tube body continues to roll, and the horizontal positioning blocks return to a vertical state to clamp the plain board, while the vertical positioning blocks are adjusted to a horizontal state. After the tube body has completely passed, the four positioning blocks are all adjusted to a vertical state, which not only achieves the purpose of adjusting the plain board, but also prevents the plain board from bending again.

[0034] (4) When the positioning block clamps the blank plate, the protrusion is used to increase the friction between the positioning block and the blank plate. That is, after the blank plate is flattened, it is positioned by the positioning block so that the blank plate remains in a horizontal state. The blank plate is flattened and the positioning block does not block the space above, which is convenient for subsequent processing operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0055] See also Figure 1-Figure 11 , the present invention provides the following technical solutions:

[0056] Embodiment 1, the automatic paper suction and turning mechanism of the double veneer panel comprises an electric lifting work platform 1 and a paper turning assembly 2 arranged on one side of the electric lifting work platform 1. The electric lifting work platform 1 can be a scissors-type electric lifting platform, which converts the inclined telescopic movement or the horizontal telescopic movement into a vertical up and down movement through the scissors-type lifting mechanism, thereby completing the lifting of the lifting platform. No specific limitation is made here. The electric lifting work platform 1 is used to carry stacked facial papers.

[0057] See also Figure 1 The paper turning assembly 2 includes a gripping mechanism 21 disposed at the rear of the electric lifting workbench 1 and an auxiliary mechanism 22 disposed at the front of the electric lifting workbench 1. The gripping mechanism 21 is suitable for adsorbing and turning over the facing paper, and the auxiliary mechanism 22 is suitable for limiting and guiding the turned facing paper. The specific structure of the gripping mechanism 21 is as follows:

[0058] See also Figure 1-Figure 3 The grabbing mechanism 21 includes a bracket 211 arranged at the rear of the electric lifting workbench 1, and the bracket 211 is arranged along the extension direction of the electric lifting workbench 1. A first electric guide rail 212 is installed on the top of the bracket 211, and a support frame 213 is slidably connected to the top of the first electric guide rail 212. The first electric guide rail 212 can be a stepper motor linear slide rail screw slide module, which is not specifically limited here. The first electric guide rail 212 is used to drive the support frame 213 to slide in the horizontal direction. A flipping rod 214 is horizontally arranged on the side of the support frame 213 facing the electric lifting workbench 1, and a plurality of paper turning suction cups 218 are equidistantly installed at the bottom of the flipping rod 214. When the support frame 213 is displaced, the flipping rod 214 and the paper turning suction cup 218 can be driven to move synchronously. The paper turning suction cup 218 is used to absorb the stacked facial paper on the top of the electric lifting workbench 1, and transfer the facial paper through the first electric guide rail 212.

[0059] See also Figure 2 and Figure 3A lifting cylinder 215 is installed on the top of the support frame 213, and the piston rod of the lifting cylinder 215 extends to the inside of the support frame 213 and is installed with a connecting frame 217. A rotating cylinder 216 is installed on the side of the connecting frame 217 away from the flipping rod 214, and the output end of the rotating cylinder 216 is connected to one end of the flipping rod 214. When the paper turning suction cup 218 needs to adsorb the facing paper, the lifting cylinder 215 pushes the connecting frame 217 and the flipping rod 214 to move down, so that the paper turning suction cup 218 can be contacted and squeezed with the facial paper. When the lifting cylinder 215 contracts, the facial paper can be lifted. When the facial paper needs to be flipped, one end of the facial paper is first lifted, and then the flipping rod 214 is driven to rotate 180 degrees by the rotating cylinder 216 to flip the facial paper. This method can achieve the purpose of adjusting the direction of the facial paper before use, which is convenient for the subsequent double-sided pasting of the plain board.

[0060] See also Figure 1 and Figure 4 The auxiliary mechanism 22 includes a vertical plate 221 arranged in front of the electric lifting workbench 1, an auxiliary motor 222 installed above the front surface of the vertical plate 221, an L-shaped plate 223 arranged above the rear surface of the vertical plate 221, and a first roller 224 and a second roller 225 connected to the side wall of the L-shaped plate 223. The output end of the auxiliary motor 222 passes through the vertical plate 221 and is connected to the side wall of the L-shaped plate 223. In order to avoid the problem that the displacement of the facial paper affects the flipping effect when the facial paper is flipped and pulled, the auxiliary mechanism 22 is used to cooperate with the facial paper limit, that is, the end of the facial paper is between the first roller 224 and the second roller 225 when flipping. After the facial paper is flipped, the first roller 224 is wrapped by the facial paper. When the end of the facial paper is sucked and pulled, the auxiliary motor 222 drives The L-shaped plate 223 swings downward, causing the first roller 224 to squeeze and limit the facial paper, while the outer wall of the second roller 225 adjusts and squeezes the wrinkles of the facial paper to prevent the other end of the facial paper from moving synchronously and affecting the flipping effect. Although the existing method uses the flipping and transfer method to lay the facial paper, it is unable to limit the wrinkled facial paper, so that the facial paper is not only wrinkled, but also the facial paper is displaced as a whole when flipped and pulled, affecting the flipping effect. The first roller 224 and the second roller 225 are swung and adjusted in height through the L-shaped plate 223, so that the first roller 224 squeezes and limits the facial paper to avoid the overall displacement of the facial paper, and the outer wall of the second roller 225 adjusts and squeezes the wrinkles of the facial paper to alleviate the wrinkle problem when the facial paper is flipped.

[0061] See also Figure 1 , Figure 5 and Figure 6 A feeding assembly 4 and a transfer assembly 3 installed on the top of the feeding assembly 4 are provided on one side of the electric lifting workbench 1. The transfer assembly 3 is suitable for transferring the facing paper, and the feeding assembly 4 is suitable for placing and conveying the transferred facing paper.

[0062] See also Figure 5 The feeding assembly 4 includes a placing table 41 arranged on one side of the electric lifting workbench 1, and a through groove is opened on the table top of the placing table 41. A feeding electric slide rail 43 is horizontally installed on the side wall of the through groove. A feeding plate 42 is slidably connected to the side wall of the feeding electric slide rail 43. The feeding electric slide rail 43 can be a stepper motor linear slide rail screw slide module, which is not specifically limited here. The feeding electric slide rail 43 is used to drive the feeding plate 42 to slide horizontally inside the through groove, that is, the flipped facial paper is transferred to the top of the feeding plate 42 through the transfer assembly 3, and the staff covers the surface of the facial paper transferred for the first time with a plain plate, and then the transfer assembly 3 transfers the unflipped facial paper to the plain plate. This state forms a pre-composite state of the plain plate and the facial paper, and the plain plate and the facial paper are sent to the processing equipment position for compounding through the feeding plate 42 to achieve the purpose of processing double-sided decorative panels.

[0063] See also Figure 5 and Figure 6 The transfer assembly 3 includes a transfer electric guide rail 31 installed on the top of the placement table 41 and a transfer frame 32 slidably connected to the top of the transfer electric guide rail 31. The transfer electric guide rail 31 can be a stepper motor linear slide rail screw slide module, which is not specifically limited here. The transfer electric guide rail 31 is used to drive the transfer frame 32 to move. An adjusting cylinder 33 is installed on the side wall of the transfer frame 32. The piston rod end of the adjusting cylinder 33 is connected to a carrier frame 36. The side wall of the carrier frame 36 is hinged with a swing A plurality of transfer suction cups 37 are equidistantly installed at the bottom of the movable frame 39 and the swing frame 39, two groups of limit blocks 34 are installed on the side wall of the transfer frame 32, and two limit rods 35 are symmetrically installed on the top of the support frame 36. The two limit rods 35 are arranged corresponding to the two groups of limit blocks 34, and the limit rods 35 are passed through the interior of the corresponding group of limit blocks 34. A driving cylinder 38 is installed vertically downward on the top of the support frame 36, and the piston rod end of the driving cylinder 38 is hinged to the top of the transfer suction cup 37.

[0064] When the transfer electric guide rail 31 drives the transfer rack 32 to move to the top of the electric lifting workbench 1, the top tissue paper in the tissue paper stock pile is completely turned over and overlapped with the stacked tissue paper stock pile again, that is, the paper turning suction cup 218 turns over and transfers the tissue paper and cancels the adsorption, and the tissue paper falls on the stacked tissue paper stock pile and overlaps again, and this tissue paper is in a reverse side facing up state, and then the paper turning suction cup 218 is moved away and reset, and then the regulating cylinder 33 is used to drive the carrier frame 36, the swing frame 39 and the transfer suction cup 37 to move downward as a whole, so that the transfer suction cup 37 contacts with the tissue paper, and then the cylinder 38 is driven to push the swing frame 39 to swing downward, causing The transfer suction cup 37 is squeezed and adsorbs the top surface of one end of the facial paper close to the feeding component 4. After the facial paper is adsorbed, the swing frame 39 returns to a horizontal state, and the supporting frame 36 moves up and reset as a whole. The transfer electric guide rail 31 drives the transfer frame 32 and the components connected to the transfer frame 32 in sequence to move synchronously to the top of the feeding component 4. Then the transfer suction cup 37 releases the facial paper. Then the staff covers the surface of the facial paper with a blank board, and then uses the transfer component 3 again to transfer the unturned facial paper to the surface of the blank board. After the facial paper and the blank board are stacked, the feeding component 4 is used to feed the material for processing.

[0065] In the second embodiment, the double-sided decorative board needs to transfer the facing paper twice. When compounding thinner plain boards or irregular plain boards, the thin plain boards and irregular plain boards will bend and warp. When the flipped facing paper is laid and the plain board is covered, the plain board and the bottom facing paper cannot be completely in contact. In this state, covering another layer of facing paper still cannot be completely attached, and may even be offset. When compounding, the facing paper and the plain board will not be completely covered.

[0066] For this purpose, see Figure 1 and Figure 7 A sorting component 5 and a positioning component 6 are installed on the top of the feeding component 4. The sorting component 5 is suitable for leveling the facing paper. The positioning component 6 includes a shell 61 installed on the top of the feeding plate 42. The shell 61 is used to carry the special-shaped plain board and the facing paper.

[0067] See also Figure 7 and Figure 8 The sorting component 5 includes a sorting frame 51 installed on the top of the feeding component 4 and two sorting cylinders 52 hinged to the side wall of the sorting frame 51. A tube body 53 is rotatably connected between the ends of the piston rods of the two sorting cylinders 52. When the turned-over facial paper is laid on the top of the shell 61, the tube body 53 is driven by the sorting cylinder 52 to move, causing the tube body 53 to roll on the top of the facial paper and the shell 61, thereby flattening the facial paper.

[0068] See also Figure 7 and Figure 8The finishing component 5 also includes two sleeve rings 54 which are sleeved on the outer wall of the tube body 53 and are symmetrically arranged. A spring 55 is connected between the opposite sides of the two sleeve rings 54 and the outer wall of the tube body 53. The outer wall of the tube body 53 is symmetrically provided with two slide grooves 56. The two slide grooves 56 are arranged corresponding to the two sleeve rings 54. A guide block 58 is connected to the inner wall of each sleeve ring 54. The guide block 58 on the inner wall of the sleeve ring 54 is slidably connected to the inside of the corresponding slide groove 56. Two guide cylinders 57 are installed inside the tube body 53. The two guide cylinders 57 are arranged corresponding to the two sleeve rings 54. The piston rods of the guide cylinders 57 are connected to the side walls of the corresponding guide blocks 58. After the surface paper is leveled, the staff places the special-shaped blank board on the top of the shell 61 and adjusts the bottom The top surface paper is covered. After the surface paper and the plain board are placed, the tube body 53 is used again to roll and flatten the top surface paper and the plain board. At the same time, the guide cylinder 57 is used to push the corresponding guide block 58 to slide inside the corresponding slide groove 56, so that the ring 54 slides on the outer wall of the tube body 53, and the two groups of rings 54 squeeze the side wall of the plain board, so that during the flattening process of the top surface paper and the plain board, the ring 54 is used to assist in positioning the bottom surface paper, and at the same time, the position of the plain board is clamped and positioned. Then the transfer component 3 transfers another piece of surface paper to cover the plain board, and the tube body 53 and the ring 54 cooperate to squeeze the fitting position between the plain board and the surface paper, and adjust the position of the plain board again to ensure that there is no uncovered part between the plain board and the bottom surface paper.

[0069] In the third embodiment, even if the plain board is flattened, the plain board will still return to a bent state due to the stress on the element board. The bent plain board will still affect the top surface paper, causing the top surface paper to deviate.

[0070] For this purpose, see Figure 9-11 Four positioning grooves 62 are provided at the four corners of the top of the shell 61, and a positioning block 63 is slidably connected inside each positioning groove 62. A fixing plate 64 is installed inside the shell 61, and a positioning electric guide rail 65 is installed on the top of the fixing plate 64. Two sliders 66 are slidably connected to the top of the positioning electric guide rail 65, and each slider 66 is arranged corresponding to two of the positioning blocks 63, and the positioning block 63 is rotatably connected to the side wall of the corresponding slider 66. The positioning electric guide rail 65 can be a stepper motor linear slide rail lead screw slide module, and the lead screw of the positioning electric guide rail 65 is a bidirectional threaded lead screw. When the bidirectional threaded lead screw rotates, since the bidirectional threaded lead screw has two threads in opposite directions, the two moving blocks can be moved toward or away from each other at the same time. No specific limitation is made here. The positioning electric guide rail 65 is used to drive the sliders 66 to move closer to or away from each other. When the two sliders 66 approach each other, the corresponding positioning block 63 can be driven to approach the direction of the plain plate, thereby clamping and positioning the plain plate.

[0071] See also Figure 9-11The positioning block 63 is provided with a protrusion 68 toward the middle of the shell 61. When the positioning block 63 clamps the plain board, the protrusion 68 is used to increase the friction between the positioning block 63 and the plain board. That is, after the plain board is flattened, it is positioned by the positioning block 63 so that the plain board remains in a horizontal state.

[0072] Two positioning cylinders 67 are hingedly installed on the top of each slider 66, and the side walls of the two positioning blocks 63 corresponding to the slider 66 are connected with rotating rods 69. The piston rods of the two positioning cylinders 67 correspond to the rotating rods 69 on the side walls of the two positioning blocks 63 and are rotatably connected.

[0073] The positioning cylinder 67 is used to drive the corresponding rotating rod 69 to move, so that the rotating rod 69 drives the corresponding positioning block 63 to swing, so that the positioning block 63 can be retracted or erected from the corresponding positioning groove 62. When the piston rod of the positioning cylinder 67 is extended, the positioning block 63 swings to a horizontal state and is retracted into the positioning groove 62. When the piston rod of the positioning cylinder 67 is retracted, the positioning block 63 swings to a vertical state and stands up. The adjustment of this state can not only avoid the interference between the positioning block 63 and the tube body 53, but also play a positioning role for the plain plate.

[0074] Specifically, when the plain board and the facial paper are placed on the top of the shell 61, the tidying cylinder 52 is in a fully extended state at this time, and then the piston rod of the tidying cylinder 52 gradually contracts, and the plain board and the facial paper are flattened by the rolling of the tube body 53. During the flattening process, the tube body 53 first passes through the two positioning blocks 63 opposite to the protrusion 68. At this time, the positioning cylinders 67 corresponding to the two positioning blocks 63 operate, causing the positioning blocks 63 to contract into the corresponding positioning grooves 62, while the other two positioning blocks 63 are in a vertical state. After the tube body 53 passes through the horizontal positioning blocks 63, Since the tube body 53 is still in a state of squeezing the plain board, the plain board at the position of the horizontal positioning block 63 remains horizontal. At this time, the horizontal positioning block 63 swings to a vertical state and clamps the plain board, while the other two vertical positioning blocks 63 are adjusted to a horizontal state. The tube body 53 continues to roll to squeeze the plain board. After the tube body 53 passes through four positioning blocks 63, the horizontal positioning block 63 returns to a vertical state again. At this time, the plain board is flattened and is in a horizontal state, and the positioning block 63 does not block the space above the plain board, thereby facilitating subsequent processing operations.

[0075] Embodiment 4, a working method of the automatic paper suction and turning mechanism of a double veneer panel, using the automatic paper suction and turning mechanism of the double veneer panel as described above, comprises the following steps:

[0076] S1. The facial tissue is stacked on the top of the electric lifting workbench 1. The height of the facial tissue is adjusted by the electric lifting workbench 1. When the facial tissue is used, the gripping mechanism 21 is first used to adsorb and flip the top surface of one end of the facial tissue away from the feeding assembly 4. Then, the gripping mechanism 21 drives the flipped end of the facial tissue to move horizontally.

[0077] The more specific steps of S1 are:

[0078] S11. The facial paper is stacked on the top of the electric lifting workbench 1, and the height of the facial paper is adjusted by the electric lifting workbench 1. When the facial paper is used, the lifting cylinder 215 drives the connecting frame 217, the turning rod 214 and the paper turning suction cup 218 to move downward as a whole, so that the paper turning suction cup 218 adsorbs the top surface of the end of the facial paper away from the feeding component 4, and then the rotating cylinder 216 drives the turning rod 214, the paper turning suction cup 218 and the adsorbed facial paper end to turn over. After the facial paper end is turned over, the first electric guide rail 212 drives the support frame 213 and the various components installed on the support frame 213 to move as a whole, so that the turned facial paper end moves horizontally toward the feeding component 4.

[0079] S2. When the tissue paper is turned over, it is between the first roller 224 and the second roller 225. After the tissue paper is turned over, the first roller 224 is wrapped by the tissue paper. When the end of the tissue paper is sucked and pulled, the auxiliary motor 222 drives the L-shaped plate 223 to swing downward, causing the first roller 224 and the second roller 225 to squeeze and limit the tissue paper.

[0080] S3, after the facial paper is completely turned over, it overlaps with the stacked facial paper pile again, and then the transfer component 3 absorbs the turned facial paper and pulls it to the top of the feeding component 4 and covers it on the top of the positioning component 6, and then the finishing component 5 is used to flatten the facial paper.

[0081] The more specific steps of S3 are:

[0082] S31, after the facial paper is completely turned over, it overlaps with the stacked facial paper pile again, and then the transfer electric guide rail 31 drives the transfer frame 32 to move to the top of the electric lifting workbench 1, and the adjustment cylinder 33 drives the load frame 36, the swing frame 39 and the transfer suction cup 37 to move downward as a whole, so that the transfer suction cup 37 contacts with the facial paper, and then the driving cylinder 38 pushes the swing frame 39 to swing downward, so that the transfer suction cup 37 is squeezed and adsorbed on the top surface of one end of the facial paper close to the feeding component 4.

[0083] S32, after the facial paper is adsorbed, the swing frame 39 returns to the horizontal state, and the supporting frame 36 moves up and reset as a whole, and the transfer electric guide rail 31 drives the transfer frame 32 and the components connected to the transfer frame 32 in sequence to move synchronously to the top of the feeding component 4, and then the transfer suction cup 37 releases the facial paper, and the facial paper covers the top of the shell 61.

[0084] S33, the placed tissue paper is driven by the arranging cylinder 52 to move the tube body 53, so that the tube body 53 rolls on the tissue paper and the top of the shell 61, thereby flattening the tissue paper.

[0085] S4, the plain board is covered on the flattened surface paper, and then the surface paper on the top of the electric lifting workbench 1 is adsorbed and transferred to the plain board by the transfer component 3, and the surface paper does not need to be turned over.

[0086] S5. After the placement of the face paper and the plain board is completed, the tube body 53 is used again to roll and flatten them, and then the side wall of the flattened plain board is positioned by the positioning block 63. After the positioning of the plain board is completed, the feeding component 4 is used to feed the plain board and the face paper to the processing equipment for compounding.

[0087] The more specific steps of S5 are:

[0088] S51, after the placement of the face paper and the blank board is completed, the tube body 53 is used again to roll and flatten the top face paper and the blank board. At the same time, the guide cylinder 57 is used to push the corresponding guide block 58 to slide inside the corresponding slide groove 56, causing the ring 54 to slide on the outer wall of the tube body 53. The two groups of rings 54 squeeze the side wall of the blank board, so that during the flattening process of the top face paper and the blank board, the ring 54 is used to assist in positioning the bottom face paper until the sorting cylinder 52 is fully extended.

[0089] S52, then the tube body 53 rolls in the opposite direction, and the piston rod of the tidying cylinder 52 gradually shrinks. During the flattening process, the tube body 53 first passes through the two positioning blocks 63 opposite to the protrusions 68. At this time, the positioning cylinders 67 corresponding to the two positioning blocks 63 operate, causing the positioning blocks 63 to shrink into the corresponding positioning grooves 62, while the other two positioning blocks 63 are in a vertical state. After the tube body 53 passes through the horizontal positioning block 63, since the tube body 53 is still in a state of squeezing the plain board, the plain board at the position of the horizontal positioning block 63 remains horizontal. At this time, the horizontal positioning block 63 swings to a vertical state and clamps the plain board in position, while the other two vertical positioning blocks 63 are adjusted to a horizontal state, and the tube body 53 continues to roll to squeeze the plain board. After the tube body 53 passes through four positioning blocks 63, the horizontal positioning block 63 returns to a vertical state again. At this time, the plain board is in a horizontal state after being flattened.

[0090] S53. Finally, the feeding electric slide rail 43 is used to drive the feeding plate 42 to move, and the plain plate and the surface paper are sent to the processing equipment for compounding.

[0091] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
