Technical Field
[0001] The present invention relates to the technical field of paper packaging box processing, and particularly to an expandable integrated structure for stacking and conveying paper packaging boxes. Background Art
[0002] As is well known, during the processing of paper packaging boxes, after plate making, printing, and indentation, stacking, packaging, and bundling are required for convenient long-distance transportation. The purpose of stacking in this process is to fix a large number of un-folded paper packaging box products into a whole, effectively reducing the occupied space and facilitating subsequent processing.
[0003] When processing paper packaging boxes, stacking and conveying devices are needed. The problems existing in the prior art are as follows: Most stacking relies on gravity or grabs the box products by a robot and then stacks the sheet materials of the box products. Then, the sheet materials are transported to a position convenient for continued bundling or packaging together with the tray by a feeding trolley or a forklift. Although in this process, the finished sheet materials can be directly introduced to the top of the tray by piecing, in this process, it is limited by the size of the tray and the shape of the finished sheet materials. Since the finished sheet materials need to be folded and have self-adhesive edges, they are prone to misalignment or position deviation during the stacking process. Moreover, the stacking method is limited by the vertical height of the front conveying equipment because it is difficult to stack the sheet materials higher than the height of equipment such as the conveying belt during the stacking process. Therefore, the use process is relatively limited. Based on the above-mentioned problems, we found that it is difficult for the existing paper packaging box stacking and conveying devices to avoid the above problems at the same time. Therefore, we propose an expandable integrated structure for stacking and conveying paper packaging boxes to solve the above existing problems. Summary of the Invention
[0004] Aiming at the deficiencies of the prior art, the present invention provides an expandable integrated structure for stacking and conveying paper packaging boxes, which has the advantages of being able to limit the position of the finished sheet materials of the packaging boxes at a relatively low cost during stacking, making them relatively flat during stacking, and at the same time not being limited by the vertical height of the front conveying equipment during stacking, and being able to flexibly adjust the number of different stacks according to the needs by selecting different trays.
[0005] The above technical objectives of the present invention are achieved through the following technical solutions: An expandable integrated structure for stacking and conveying paper packaging boxes includes a stacking and conveying frame and a conveyor belt. The conveyor belt is installed on the right side of the stacking and conveying frame. A track is provided at the bottom inside the stacking and conveying frame, and a feeding trolley is movably connected to the top of the track. A stacking tray is movably connected to the top of the feeding trolley. The stacking and transporting rack includes a frame body. Two side frames are fixedly connected to the right side of the frame body. A first electric cylinder is fixedly connected to the right side of the top side frame. The telescopic end of the first electric cylinder penetrates through the side frame and is fixedly connected to a sliding plate frame. A second electric cylinder is installed inside the bottom side frame. The telescopic end of the second electric cylinder is fixedly connected to a stacking and warping frame; The stacking tray includes three cross beams. A sliding frame is fixedly connected to the rear side of the cross beam. A concave frame is fixedly connected to the front side of the cross beam. A corner frame is fixedly connected to the top of the middle cross beam. A secondary beam is movably connected inside the concave frame. The rear side of the secondary beam is slidably connected to the sliding frame. Vertical plates are fixedly connected to the front side and the rear side of the top of the secondary beam. A baffle is fixedly connected to the rear side of the front vertical plate. The rear side of the baffle is fixedly connected to the rear vertical plate. Side rails are fixedly connected to the tops of the vertical plates.
[0006] With the above technical solution, a conveyor belt is provided to convey the finished paper packaging box sheets from the previous process to the stacking position of the stacking rack. During normal use, when the sheet moves to the end of the conveyor belt, the sheet will naturally fall. During this process, it will slide down along the inclined part of the slide frame of the stacking support. When it slides to the bottom, the second electric cylinder pushes the stacking frame close to the sheet and presses the sheet flat. As the number of sheets stacked on the stacking tray increases, the first electric cylinder gradually retracts and pulls the slide frame away from the stacking position to adapt to the current stacking height. Since there is no need to rely on gravity for vertical stacking, there is no length limit during stacking. You can choose a stacking tray with a longer size according to your needs to expand the maximum number of stacked sheets. When the sheet falls on the top of the stacking tray, due to the limitation of the stacking rack, it will fall vertically. Since the folding edges and other positions of the finished paper packaging box sheets always have a right angle or two sides that can form a right angle after extension, when the sheet falls, it will be limited after contacting the baffle on the top of the secondary beam, and the bottom right angle will be stuck outside the angle frame, and its two sides will fit against the baffle to achieve the effect of limiting the sheet. Since the second electric cylinder always pushes a new sheet to stack during the reciprocating movement, it will also limit the sheet during the pushing process to prevent it from tipping over. According to the different sheets to be processed, the position of the secondary beam that moves along with the concave frame and the sliding frame can also be adjusted to adjust the position of the vertical sheet and the baffle, which can be flexibly adjusted for different processed sheets. The setting of the side bar can be used as the bottom limit for stacking and effectively support the sheet. By using the right-angle edge of the sheet and the 90-degree angle frame to achieve vertical stacking, the sheets restricted by the angle during stacking will not be misaligned, etc., and no complex high-precision equipment is required. After calibration in the processing of the same batch of packaging boxes, it can be continuously used, which can reduce the equipment cost and maintenance cost to a certain extent. Before and after the stacking action, the stacking tray connected to it can be moved to the working position or the stacked stacking tray can be transported out of the stacking position by the feeding trolley. When the sheet falling along the conveyor belt is difficult to tilt, the parking position of the feeding trolley can be adjusted to make the falling position of the sheet itself deviate from the angle frame to achieve the cooperation between the sheet and the angle frame.
[0007] The present invention is further configured as: a sponge sheet is pasted on the outside of the angle frame, and an extension plate is movably connected to the top of the baffle.
[0008] With the above technical solution, by setting the sponge sheet, the angle frame will not directly contact the sheet. The paper packaging box material has a certain flexibility. During the erection and stacking process, the carton material can withstand a certain degree of deformation without damage, and its easily deformable bottom directly contacting the sponge sheet can avoid the material from deforming or bending caused by direct contact with rigid materials. The setting of the extension plate can assist the overly long side of the sheet to lean on when the sheet is too long, so as to achieve the effect of auxiliary limiting.
[0009] The present invention is further configured such that: narrow plates are fixedly connected to both the top of the side of the baffle away from the corner bracket and the bottom of the extension plate. The top narrow plate and the bottom narrow plate are movably connected by connecting bolts, and a mating groove is formed inside the narrow plate.
[0010] By adopting the above technical solution, by providing the narrow plates, it is convenient to fix the baffle and the extension plate with connecting bolts, so as to be flexibly assembled as required. The provided mating groove is relatively long, so a certain radial misalignment between the extension plate and the baffle can be allowed. When there are protruding parts such as sticking edges on the long side of the packaging box, the position of the extension plate can be adjusted to fit the protruding parts, ensuring that sheets of different shapes can be stacked stably.
[0011] The present invention is further configured such that: a ratchet plate is fixedly connected to the top inside the concave frame, a shaft bracket is fixedly connected to the top of the secondary beam, a short shaft is rotatably connected inside the shaft bracket, a ratchet tooth is fixedly connected to the outside of the short shaft, the ratchet tooth is engaged with the ratchet plate, torsion springs are fixedly connected to both sides of the ratchet tooth, the side of the torsion spring away from the ratchet tooth is fixedly connected to the shaft bracket, and the torsion spring is sleeved on the outside of the short shaft.
[0012] By adopting the above technical solution, by providing the ratchet plate in cooperation with the ratchet tooth, when the position of the secondary beam needs to be adjusted, if it needs to be moved towards the position close to the corner bracket, the secondary beam can be directly pushed to move. When the ratchet tooth contacts the ratchet plate, it will rotate along the rotating shaft, and at this time the torsion spring stores energy. When the movement of the secondary beam is stopped at the required position, the torsion spring rebounds to push the ratchet tooth to reset and be stuck in the ratchet plate. When the secondary beam moves away from the corner bracket due to the force on the top structure, the ratchet tooth is stuck inside the ratchet plate, and the outside of the shaft bracket will hold the ratchet tooth so that it cannot rotate, so displacement will not occur, so as to achieve the effect of quickly adjusting the position of the secondary beam. While moving, the secondary beam slides along the sliding frame to limit the movement of the structure.
[0013] The present invention is further configured such that: a transmission rod is fixedly connected to the outside of the short shaft, the bottom of the left side of the transmission rod is fixedly connected to the secondary beam, an anti-slip pad is sleeved on the right side of the outside of the transmission rod, and a handle is fixedly connected to the outside of the secondary beam, and the handle is arranged at the bottom of the transmission rod.
[0014] By adopting the above technical solution, by providing the transmission rod, when the position of the secondary beam needs to be adjusted to move it away from the corner bracket, the transmission rod can be pressed down to make it close to the handle. When the transmission rod is pressed down, it will rotate along the shaft bracket together with the short shaft connected thereto. At this time, the ratchet tooth connected to the short shaft will also be disengaged from the ratchet plate. After pulling the handle and the transmission rod, it can slide freely along the inside of the concave frame. When it moves to the required position, the torsion spring resets to make the ratchet tooth re-engage with the ratchet plate to complete the limitation of the structure.
[0015] The present invention is further configured such that: a chassis is fixedly connected to the top of the sliding frame, rubber legs are fixedly connected to the outside of the chassis, and a stress block is fixedly connected to the side of the chassis away from the rubber legs.
[0016] With the above technical solution, by providing the chassis, when it is necessary to change the stacking method of the sheet material from a standing-up stacking method to a flat vertical stacking method, the entire stacking tray can be rotated. After rotation, the chassis contacts the ground through the rubber legs to complete the support for the sheet material thereon. The provided stress block is in direct contact with the sheet material to assist in sharing the stress.
[0017] The present invention is further configured such that: a first rotating shaft is fixedly connected to the bottom of the sliding frame, the bottom of the first rotating shaft is movably connected to the feeding trolley, a cushion frame is fixedly connected to the bottom of the sliding frame, the top of the cushion frame is fixedly connected to the concave frame, and the bottom of the cushion frame contacts the feeding trolley.
[0018] With the above technical solution, by providing the first rotating shaft, it is convenient to rotate the sliding frame along the first rotating shaft to achieve the effect of rotating the entire stacking tray. The provided cushion frame can increase the stress area when the bottom of the stacking tray contacts the feeding trolley, so as to enhance the stress intensity of the structure.
[0019] The present invention is further configured such that: a plug block is fixedly connected to the bottom of the first rotating shaft, a plug frame is fixedly connected to the top of the feeding trolley, and the inside of the plug frame is plugged with the plug block.
[0020] With the above technical solution, by providing the plug block in cooperation with the plug frame, it is convenient to quickly insert the stacking tray together with the first rotating shaft into the plug frame through the plug block to complete the quick installation or disassembly of the stacking tray and the feeding trolley.
[0021] The present invention is further configured such that: a second rotating shaft is fixedly connected to the right side of the top of the feeding trolley, a lever is fixedly connected to the top of the second rotating shaft, and the left side of the lever is used in cooperation with the right cross beam.
[0022] With the above technical solution, by providing the second rotating shaft to connect the lever and the feeding trolley, when it is necessary to rotate the stacking tray, an external device can be used to pull the lever, so that it rotates along the second rotating shaft and the lever presses against the right cross beam with the second rotating shaft as the fulcrum, jacking up the entire stacking tray along the first rotating shaft to make it rotate.
[0023] The present invention is further configured such that: a pressure wheel is rotatably connected to the inside of the left side of the lever, and the pressure wheel contacts the bottom of the right cross beam.
[0024] With the above technical solution, by providing the pressure wheel, when the lever applies a force to the right cross beam, the pressure wheel rolls at the bottom of the right cross beam, changing the sliding friction into rolling friction, and playing the role of assisting the stress at the bottom of the stacking tray.
[0025] Compared with the prior art, the present invention provides an expandable integrated structure for stacking and conveying paper packaging boxes, which has the following beneficial effects: For the expandable integrated structure for stacking and conveying paper packaging boxes, a conveyor belt is provided to convey the finished sheet of the paper packaging box in the previous process to the stacking position of the stacking and conveying rack. During normal use, when the sheet moves to the end of the conveyor belt, the sheet will naturally fall. During this process, it will slide down along the inclined part of the sliding plate rack of the stacking support. When it slides to the bottom, the second electric cylinder pushes the stacking frame close to the sheet and presses the sheet flat. As the number of sheets stacked on the stacking tray increases, the first electric cylinder gradually retracts and pulls the sliding plate rack away from the stacking position to adapt to the current stacking height. Since it does not rely on gravity to stack vertically, there is no length limit during stacking, and a stacking tray with a longer size can be selected according to needs to expand the maximum stacking quantity. When the sheet falls on the top of the stacking tray, due to the limitation of the stacking and conveying rack, it will fall vertically. And since there are always right angles or two sides that can form a right angle after extension at the folding edges and other positions of the finished paper packaging box sheet, when the sheet falls, it will be limited after contacting the baffle on the top of the secondary beam, and the right angle at its bottom will be stuck outside the angle bracket, and its two sides will fit against the baffle to achieve the effect of limiting the sheet. And since the second electric cylinder always pushes a new sheet to stack during the reciprocating movement, it will also limit the sheet during the pushing process to prevent it from tipping over. According to the different sheets to be processed, the position of the secondary beam that moves along with the concave frame and the sliding frame can also be adjusted to adjust the position of the vertical sheet and the baffle, which can be flexibly adjusted for different processed sheets. The setting of the side bar can be used as the bottom limit for stacking and effectively support the sheet. By using the right-angle edge of the sheet and the 90-degree angle bracket to achieve vertical stacking, the sheets restricted by the angle during stacking will not be misaligned, etc., and complex high-precision equipment is not required. After calibration in the processing of the same batch of packaging boxes, it can be continuously used, which can reduce the equipment cost and maintenance cost to a certain extent. Before and after the stacking action, the stacking tray connected to it can be moved to the working position or the stacked stacking tray can be transported out of the stacking position by the feeding trolley. When the sheet falling along the conveyor belt is difficult to tilt, the parking position of the feeding trolley can also be adjusted to make the falling position of the sheet itself deviate from the angle bracket to achieve the cooperation between the sheet and the angle bracket.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0029] Embodiment 1: Please refer to Figures 1-8 , an expandable integrated structure for stacking and conveying paper packaging boxes, including a stacking and conveying rack 1 and a conveyor belt 2. The conveyor belt 2 is installed on the right side of the stacking and conveying rack 1. A track is provided at the bottom inside the stacking and conveying rack 1, and a feeding trolley 3 is movably connected to the top of the track. A stacking tray 4 is movably connected to the top of the feeding trolley 3; The stacking and conveying rack 1 includes a frame body 101. Two side frames 102 are fixedly connected to the right side of the frame body 101. The right side of the top side frame 102 is fixedly connected to a first electric cylinder 103. The telescopic end of the first electric cylinder 103 penetrates through the side frame 102 and is fixedly connected to a slide plate frame 104. A second electric cylinder 105 is installed inside the bottom side frame 102, and the telescopic end of the second electric cylinder 105 is fixedly connected to a stacking and tilting frame 106; By setting the conveyor belt 2 to convey the finished paper packaging box sheets from the previous process to the stacking position of the stacking rack 1, during normal use, when the sheet moves to the end of the conveyor belt 2, the sheet will naturally fall. During this process, it will slide down along the inclined part of the skateboard rack 104 of the stacking support. When sliding to the bottom, the second electric cylinder 105 pushes the stacking and warping rack 106 close to the sheet and presses the sheet flat. As the number of sheets stacked on the stacking tray 4 increases, the first electric cylinder 103 gradually retracts and pulls the skateboard rack 104 away from the stacking position to adapt to the current stacking height. Since there is no need to rely on gravity for vertical stacking, the stacking can be unrestricted by length during stacking. You can choose a stacking tray 4 with a longer size according to your needs to expand the maximum stacking quantity.
[0030] Among them, the top of the sliding frame 402 is fixedly connected to the chassis 15. The outer side of the chassis 15 is fixedly connected with rubber legs. One side of the chassis 15 away from the rubber legs is fixedly connected with a stress block 16. By setting the chassis 15, when it is necessary to change the stacking method of the sheet from the upright stacking method to the flat vertical stacking method, the entire stacking tray 4 can be rotated. After rotation, the chassis 15 contacts the ground through the rubber legs to complete the support of the sheet thereon. The set stress block 16 is directly in contact with the sheet to assist in sharing the stress. The bottom of the sliding frame 402 is fixedly connected with a first rotating shaft 17. The bottom of the first rotating shaft 17 is movably connected to the feeding trolley 3. The bottom of the sliding frame 402 is fixedly connected with a cushion frame 18. The top of the cushion frame 18 is fixedly connected to the concave frame 403. The bottom of the cushion frame 18 contacts the feeding trolley 3. By setting the first rotating shaft 17, it is convenient to rotate the sliding frame 402 along the first rotating shaft 17 to achieve the effect of rotating the entire stacking tray 4. The set cushion frame 18 can increase the stress area when the bottom of the stacking tray 4 contacts the feeding trolley 3 to enhance the stress intensity of the structure. The bottom of the first rotating shaft 17 is fixedly connected with an insertion block 19. The top of the feeding trolley 3 is fixedly connected with an insertion frame 20. The inner side of the insertion frame 20 is inserted with the insertion block 19. By setting the insertion block 19 in cooperation with the insertion frame 20, it is convenient to quickly insert the stacking tray 4 together with the first rotating shaft 17 into the insertion frame 20 through the insertion block 19 to complete the quick installation or disassembly of the stacking tray 4 and the feeding trolley 3. The right side of the top of the feeding trolley 3 is fixedly connected with a second rotating shaft 21. The top of the second rotating shaft 21 is fixedly connected with a lever 22. The left side of the lever 22 is used in cooperation with the right cross beam 401. By setting the second rotating shaft 21 to connect the lever 22 and the feeding trolley 3, when it is necessary to rotate the stacking tray 4, an external device can be used to pull the lever 22 to make it rotate along the second rotating shaft 21 so that the lever 22 presses against the right cross beam 401 with the second rotating shaft 21 as the fulcrum, and the entire stacking tray 4 is lifted along the first rotating shaft 17 to make it rotate. The inner side of the left side of the lever 22 is rotatably connected with a pressing wheel 23. The pressing wheel 23 contacts the bottom of the right cross beam 401. By setting the pressing wheel 23, when the lever 22 applies a force to the right cross beam 401, the pressing wheel 23 rolls on the bottom of the right cross beam 401, changing the sliding friction into rolling friction, and playing an auxiliary role in stressing the bottom of the stacking tray 4.
[0031] Working principle of this embodiment: First, insert the stacking tray 4 into the insertion frame 20 on the feeding trolley 3 through the insertion block 19 at the bottom of the first rotating shaft 17 to complete the rapid installation of the stacking tray 4 and the feeding trolley 3. During normal operation, the conveyor belt 2 conveys the paper packaging box finished sheets from the previous process to the stacking position of the stacking and conveying rack 1. After the sheets move to the end of the conveyor belt 2, they fall naturally. During the falling process, they slide down along the inclined part of the sliding plate frame 104. When the sheets slide to the bottom, the second electric cylinder 105 pushes the stacking and warping frame 106 close to the sheets and presses and flattens the sheets. As the number of sheets on the stacking tray 4 increases, the first electric cylinder 103 gradually retracts, pulling the sliding plate frame 104 away from the stacking position to adapt to the continuously increasing stacking thickness. After the stacking is completed, according to actual requirements, if it is necessary to adjust the stacking tray 4 from standing stacking to flat vertical stacking, an external device can be used to pull the lever 22 on the feeding trolley 3. The lever 22 takes the second rotating shaft 21 as the fulcrum, drives the pressing wheel 23 to press against the right cross beam 401, and jacks up the entire stacking tray 4 along the first rotating shaft 17. During the rotation process, the pressing wheel 23 rolls at the bottom of the right cross beam 401 to reduce friction and assist in bearing the force. After the rotation is completed, the bottom frame 15 contacts the ground through the rubber legs to provide support for the sheets on the stacking tray 4. The stress block 16 contacts the sheets to assist in sharing the force. At the same time, the cushioning frame 18 increases the contact area between the bottom of the stacking tray 4 and the feeding trolley 3, enhancing the structural stress strength.
[0032] Embodiment 2: Refer to Figures 1-7 , an expandable integrated structure for stacking and conveying paper packaging boxes further includes a stacking tray 4. Among them, the stacking tray 4 includes three cross beams 401. A sliding frame 402 is fixedly connected to the rear side of the cross beam 401. A concave frame 403 is fixedly connected to the front side of the cross beam 401. A corner frame 404 is fixedly connected to the top of the middle cross beam 401. A secondary beam 405 is movably connected to the inside of the concave frame 403. The rear side of the secondary beam 405 is slidably connected to the sliding frame 402. Vertical pieces 406 are fixedly connected to the front side and the rear side of the top of the secondary beam 405. A baffle 407 is fixedly connected to the rear side of the front vertical piece 406. The rear side of the baffle 407 is fixedly connected to the rear vertical piece 406. A side bar 408 is fixedly connected to the top of the vertical piece 406; When the sheet falls onto the top of the stacking tray 4 through the conveyor belt 2, it will fall vertically due to the limit of the stacking rack 1. Since the folding edges of the finished paper packaging box sheet always have right angles or two sides that can form a right angle after extension, when the sheet contacts the baffle 407 on the top of the secondary beam 405 during the fall, it will be limited, and the right angle at its bottom will be stuck outside the angle bracket 404. The two sides on both sides will fit against the baffle 407 to achieve the effect of limiting the sheet. Since the second electric cylinder 105 always pushes a new stack of sheets during the reciprocating movement, it will also limit the sheet during the pushing process to prevent it from tipping over. According to the different sheets to be processed, the position of the secondary beam 405 that moves along with the concave frame 403 and the sliding frame 402 can also be adjusted to adjust the positions of the vertical sheet 406 and the baffle 407, which can be flexibly adjusted for different processed sheets. The setting of the side bar 408 can be used as the bottom limit for stacking, effectively supporting the sheet. The vertical stacking is achieved by using the right-angle edge of the sheet and the 90-degree angle bracket 404. During the stacking process, the sheets restricted by the angle will not be misaligned, etc., and complex high-precision equipment is not required. After the calibration of the packaging boxes in the same batch, it can be continuously used, which can reduce the equipment cost and maintenance cost to a certain extent. Before and after the stacking action, the stacking tray 4 connected to it can be moved to the working position or the stacked stacking tray 4 can be transported out of the stacking position by the feeding trolley 3. When the sheet falling along the conveyor belt 2 is difficult to tilt, the parking position of the feeding trolley 3 can also be adjusted to make the falling position of the sheet itself deviate from the angle bracket 404 to achieve the cooperation between the sheet and the angle bracket 404.
[0033] Among them, a sponge sheet 5 is pasted on the outer side of the tripod 404, and an extension plate 6 is movably connected to the top of the baffle 407. By setting the sponge sheet 5, the tripod 404 will not directly contact the sheet material. The paper packaging box material has a certain flexibility. During the erection and stacking process, the carton material can withstand a certain degree of deformation without damage, and its easily deformable bottom directly contacts the sponge sheet 5, which can avoid the deformation or bending of the material caused by direct contact with rigid materials. The setting of the extension plate 6 can assist the long side of the sheet to lean on when the sheet is too long, so as to play an auxiliary limiting effect. Narrow plates 7 are fixedly connected to the top of the side of the baffle 407 away from the tripod 404 and the bottom of the extension plate 6. The top narrow plate 7 and the bottom narrow plate 7 are movably connected by connecting bolts. A fitting groove is provided inside the narrow plate 7. By setting the narrow plate 7, it is convenient to fix the baffle 407 and the extension plate 6 through the connecting bolts, so as to assemble flexibly as required. The set fitting groove is relatively long, so a certain radial misalignment between the extension plate 6 and the baffle 407 is allowed. When there are protruding parts such as adhesive edges on the long side of the packaging box, the position of the extension plate 6 can be adjusted to fit the protruding part, ensuring that sheets of different shapes can be stacked stably. A ratchet plate 8 is fixedly connected to the top inside the concave frame 403, a shaft frame 9 is fixedly connected to the top of the secondary beam 405, a short shaft 10 is rotatably connected to the inside of the shaft frame 9, a ratchet 11 is fixedly connected to the outside of the short shaft 10, and the ratchet 11 is engaged with the ratchet plate 8. Torsion springs 12 are fixedly connected to both sides of the ratchet 11, and the side of the torsion spring 12 away from the ratchet 11 is fixedly connected to the shaft frame 9. The torsion spring 12 is sleeved on the outside of the short shaft 10. By setting the ratchet plate 8 to cooperate with the ratchet 11, when the position of the secondary beam 405 needs to be adjusted, if it needs to move towards the position close to the tripod 404, the secondary beam 405 can be directly pushed to move. When the ratchet 11 contacts the ratchet plate 8, it will rotate along the rotating shaft. At this time, the torsion spring 12 stores energy. When the movement of the secondary beam 405 stops at the required position, the torsion spring 12 rebounds and can push the ratchet 11 to reset and be stuck in the ratchet plate 8. When the secondary beam 405 moves away from the tripod 404 due to the force on the top structure, the ratchet 11 is stuck inside the ratchet plate 8, and the outside of the shaft frame 9 will block the ratchet 11 to prevent it from rotating, so it will not displace, so as to quickly adjust the position of the secondary beam 405. At the same time, when moving, the secondary beam 405 slides along the sliding frame 402 to limit the movement of the structure. A transmission rod 13 is fixedly connected to the outside of the short shaft 10. The bottom of the left side of the transmission rod 13 is fixedly connected to the secondary beam 405. An anti-slip pad is sleeved on the right side of the outside of the transmission rod 13. A handle 14 is fixedly connected to the outside of the secondary beam 405, and the handle 14 is arranged at the bottom of the transmission rod 13. By setting the transmission rod 13, when the position of the secondary beam 405 needs to be adjusted to make it away from the tripod 404, the transmission rod 13 can be pressed down to make it close to the handle 14. When the transmission rod 13 is pressed down, it will rotate along the shaft frame 9 together with the short shaft 10 connected to it. At this time, the ratchet 11 connected to the short shaft 10 will also be disengaged from the ratchet plate 8,After pulling the handle 14 and the transmission rod 13, they can slide freely along the inner side of the concave frame 403. When moving to the desired position, the torsion spring 12 resets, causing the ratchet 11 to re-engage with the ratchet plate 8 to complete the structural limit.
[0034] Working principle of this embodiment: First, according to the size and shape of the sheet to be processed, adjust the position of the auxiliary beam 405. When moving it towards the corner bracket 404, directly push the auxiliary beam 405. When the ratchet 11 contacts the ratchet plate 8, it rotates along the rotating shaft, and the torsion spring 12 stores energy. Stop pushing when reaching the desired position. The torsion spring 12 rebounds to reset the ratchet 11 and lock it in the ratchet plate 8, completing the position adjustment of the auxiliary beam 405 close to the corner bracket 404. At the same time, the auxiliary beam 405 slides along the sliding frame 402 to limit the movement. When moving away from the corner bracket 404, press down the transmission rod 13 to make it close to the handle 14. The transmission rod 13 drives the short shaft 10 to rotate along the shaft bracket 9, and the ratchet 11 disengages from the ratchet plate 8. Pull the handle 14 and the transmission rod 13 to make the auxiliary beam 405 slide freely along the inner side of the concave frame 403 to the desired position. Release the transmission rod 13, and the torsion spring 12 resets to make the ratchet 11 re-engage with the ratchet plate 8, completing the position adjustment of the auxiliary beam 405 away from the corner bracket 404. If the sheet is too long, connect the narrow plate 7 at the bottom of the extension plate 6 and the narrow plate 7 at the top of the baffle 407 with connecting bolts. Use the longer mating groove inside the narrow plate 7 to adjust the radial position between the extension plate 6 and the baffle 407 according to the protruding parts such as the pasting edge on the long side of the packaging box to ensure that it can fit the protruding part of the sheet. When the sheet falls, the right angle formed by its folding edge contacts the baffle 407 at the top of the auxiliary beam 405, and the bottom right angle is stuck outside the corner bracket 404. The two side edges are attached to the baffle 407. The second electric cylinder 105 reciprocates to push the stacked new sheets, and at the same time limits the sheet to prevent it from tipping over. If the sheet falling along the conveyor belt 2 is difficult to tilt, adjust the parking position of the feeding trolley 3 to make the falling position of the sheet deviate from the corner bracket 404 to achieve the cooperation between the sheet and the corner bracket 404.
