Abstract
Description
Technical Field
[0001] This invention relates to the field of paper box processing equipment technology, specifically a fully automatic folding box assembly and forming machine. Background Technology
[0002] Cardboard boxes are three-dimensional objects obtained by cutting, creasing, gluing, assembling, and folding one or more pieces of cardboard. They can be used to package various items to prevent damage from collisions during transportation. Various patterns can also be printed on their surface to enhance their aesthetics. As living standards improve, the demand for cardboard boxes is increasing. Traditional manual production has been gradually replaced by various mechanical production equipment due to its low efficiency.
[0003] In the process of producing finished folding cardboard boxes, multiple production steps are required. As a result, the cardboard may shift during movement, which can affect the accuracy of subsequent gluing and assembly, increasing the scrap rate. At the same time, the transfer and folding actions require multiple power sources, resulting in high energy consumption. In addition, in order to ensure that the various power sources can work together, a lot of time is usually spent on coordination before formal production, which is quite troublesome. Moreover, compared to fewer power sources, more power sources also increase the probability of equipment maintenance, which may affect normal production efficiency to some extent.

[0019] Working Principle: During operation, the worker places the crimped cardboard body at the rear top of the workbench. The crimped side panels and inner lining cardboard, required for assembly, are then placed sequentially from back to front in the areas where the trapezoidal blocks are located. At this point, the stepper motor is activated, causing the fixing plate to rotate. The connecting plate, connected to the fixing plate, is simultaneously pulled by the fixing plate, causing the mounting plate and push plate to reciprocate in an elliptical motion. This, combined with the pre-drilled grooves at the top of the workbench, allows the push plate to contact the concave surfaces at the rear of the cardboard body from both sides. Furthermore, by applying a pushing force to move the cardboard body forward through each processing step, the system ensures that the cardboard does not skew, thus preventing interference with subsequent gluing. Folding prevents an increase in scrap rate. After the pusher moves diagonally downward with the mounting plate, it can gradually separate from the cardboard body. At this time, the cardboard body can move to the area where the rear dispensing robot arm is located. Before the pusher contacts the cardboard body again, the rear dispensing robot arm can apply glue to both sides of the upper surface of the cardboard body. When the pusher rotates diagonally upward and contacts the cardboard body again, the glued cardboard body can move to below the second rear fixing plate. Since the stepper motor can also drive the incomplete gear to rotate synchronously when it rotates, under the action of the partial convex teeth on the surface of the incomplete gear, the convex teeth at the front and rear of the tooth plate can mesh with the incomplete gear in turn, causing the tooth plate to move back and forth in the vertical direction. At this time, through the upright plate and with the cooperation of the guide rod, the movable plate can be driven to fix the plate. The second plate moves up and down synchronously to transmit the rotation output of the stepper motor to other moving parts, thus fully utilizing the stepper motor. Since the length of the first rotating plate is fixed and it is connected to both the second fixed plate and the slider, when the second fixed plate moves up with the movable plate, the first rotating plate rotates to a certain extent, causing the slider to move closer to the trapezoidal block along the worktable. Then, under the action of the first support plate, the first spring, and the second guide rod, the first U-shaped plate can move the second connecting plate synchronously. When the second connecting plate contacts the first trapezoidal block via the inclined surface, the first trapezoidal block applies a force to the second connecting plate via the inclined surface, causing the second connecting plate to overcome the thrust of the first spring and move downwards along the inclined surface. After the second connecting plate moves down a certain distance, the suction cup can contact the side plate, and... As the suction cup continues to move downwards, the air inside is squeezed out, allowing it to adhere to the side cardboard surface under external air pressure. As the movable plate changes from upward to downward movement, the rotating plate can reverse its movement, causing the connecting plate to return. Once the connecting plate separates from the trapezoidal block, the suction cup, under the action of spring one, can move the side cardboard upwards a certain distance to avoid collision with the push plate. Simultaneously, as the connecting plate moves the side cardboard closer to the top of the cardboard body, the pressure column connected to the movable plate can move the pressure block one closer to the cardboard body. After the pressure column contacts the connecting plate, the connecting plate can overcome the spring force of spring one and move downwards again, allowing the side cardboard to contact the glued part of the cardboard body, thus completing the side cardboard assembly. At the same time, the pressure block one can contact the pressure plate.When the side cardboard and the cardboard body are flattened under pressure, the pressure plate is pushed to move the baffle downwards, causing the baffle to leave the inside of the channel. Connecting plate three can also move with the pressure plate. Therefore, under the transmission of the connecting rod, the hollow block no longer adheres to the limiting cylinder, and the limiting cylinder no longer blocks the evenly distributed arc-shaped ventilation channels. Thus, outside air can enter the air chamber through the channel, and then enter the limiting cylinder and suction cup through the arc-shaped ventilation channels, making the air pressure inside and outside the suction cup the same, thereby canceling the suction effect of the suction cup on the side cardboard. Similarly, the pusher plate continues to apply pushing force to the cardboard body, causing it to move to the middle of the dispensing robot arm and complete the secondary glue application, and then continue moving to the front. After the second fixed plate is positioned below, the inner lining cardboard can be assembled again through the front rotating plate, connecting plate, suction cup, and pressure block. This achieves the goal of using the linkage between mechanical structures to replace the power source, saving energy, making it more environmentally friendly and economical, and ensuring more reliable transmission with a low failure rate. Furthermore, after the side cardboard and inner lining cardboard are assembled and glue is applied by the front dispensing robot arm, the cardboard can be moved to the surface of the horizontal plate under the pusher plate. Simultaneously, as the movable plate moves downward, the connecting frame can drive the pressure block to move downward until it contacts the cardboard on the surface of the horizontal plate. At this point, the hydraulic rod is activated, allowing the horizontal plate to move upward. The weight of the counterweight allows the rotating plate to pull the front and rear side ladders. Since the two trapezoidal blocks are close to each other, when the horizontal plate two transmits the upward thrust to the trapezoidal block two through the rotating plate three, the horizontal displacement of the trapezoidal block two can be canceled out. Then, under the overall movement of the horizontal plate two, the trapezoidal block two can push the folding cardboard one and the irregular plate upwards. This ensures that after the folding cardboard one pushes the side cardboard to rotate 90 degrees, its central area is in contact with both sides of the pressure block two. Furthermore, after the inclined plate and the irregular plate contact each other, their contacting inclined surfaces allow the two irregular plates to approach each other. This allows the front and rear parts of the side cardboard to be in contact with the front and rear ends of the pressure block two. As the folding cardboard one continues to move upwards, the bottom plane of the inclined plate can contact the folding cardboard one, thus preventing the folding cardboard one from moving further. As the hydraulic rod continues to increase the thrust on the horizontal plate two, the horizontal thrust on the trapezoidal block two will overcome the tension exerted on it by the counterweight. This allows the limiting rod two to move upwards along the interior of the T-shaped plate, while the rotating plate three rotates, pushing the trapezoidal block two closer to the trapezoidal block three. Furthermore, after the trapezoidal block two contacts the trapezoidal block three, the trapezoidal block three can use its inclined surface to move the folding cardboard two upwards along the limiting rod three, pushing the cardboard body and inner lining cardboard to rotate 90 degrees and fit against the front and rear ends of the pressing block two. The glued portion of the inner lining cardboard applied by the front gluing robot arm can also contact the side cardboard for bonding, achieving automatic forming without manual intervention.
[0020] This invention provides a fully automatic folding box assembly and molding machine. It has the following beneficial effects:
[0021] 1. This invention uses a stepper motor to enable a fixed plate to drive a connecting plate to reciprocate along an elliptical trajectory. This allows the cardboard body to pass through each processing step sequentially while allowing sufficient processing time, eliminating the need for repeated start-stop cycles. Simultaneously, the mounting plate and push plate apply a pushing force to the rear of the cardboard body from both sides, preventing deviation during movement due to the corresponding concave surface at the rear. This avoids deviations in dispensing and assembly, reducing the scrap rate. Furthermore, the assembly mechanism converts a portion of the stepper motor's output rotation into the power required for assembling the side and inner cardboard sheets. This allows for precise completion of the gripping, transferring, and pressing of the side and inner cardboard sheets during the intermittent movement of the cardboard body, avoiding cumbersome debugging work. The reduction in power source not only saves energy and aligns with green production principles but also reduces maintenance difficulty and frequency through the reliability of the mechanical structure.
[0022] 2. The present invention, through the setting of the folding mechanism, can complete the three-dimensional folding and forming of the folding box with the cooperation of part of the assembly mechanism. It has high work efficiency and reliability, requires no manual intervention, and is suitable for the long-term production needs of large batches of folding boxes.
[0023] 3. This invention integrates various processing steps through the cooperation between mechanisms, greatly reducing the footprint of production equipment, avoiding repetitive loading and unloading, and saving manpower and resources. Attached Figure Description

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 This invention provides a fully automatic folding box assembly and forming machine, comprising:
[0037] Workbench 1, which is used to provide a basic support surface;
[0038] The protective cover 4 is fixedly connected to the top of the workbench 1 at its bottom end. Multiple dispensing robotic arms 5 are fixedly connected to the top of the inner side of the protective cover 4. Stepper motors 6 are fixedly connected to the front and rear sides of both sides of the workbench 1. Fixed plates 7 are fixedly connected to the output ends of the multiple stepper motors 6. Connecting plates 8 are rotatably connected to the ends of the two fixed plates 7 that are close to each other. Multiple mounting plates 9 are fixedly connected to the ends of the two connecting plates 8 that are close to each other. Push plates 10 are fixedly connected to the top sides of the multiple mounting plates 9.
[0039] The protective cover 4 can fix and support the evenly distributed dispensing robotic arms 5, so that each dispensing robotic arm 5 can move stably to complete the glue application at different positions, which is conducive to the subsequent assembly of the side cardboard and inner cardboard and the overall forming and fixing of the carton. The stepper motor 6 can drive the fixed plate 7 to rotate. Since the front and rear sides of the connecting plate 8 are connected to the fixed plate 7, the connecting plate 8 can perform a reciprocating rotational motion in an elliptical trajectory under the support and drive of the fixed plate 7. This allows the mounting plate 9 connected to the connecting plate 8 to drive the push plate 10 to move synchronously. When the push plate 10 moves upward and passes through the groove reserved on the surface of the worktable 1, it can gradually connect with the cardboard body. The body contacts and pushes the cardboard body forward. When the pusher plate 10 moves downward, it can gradually separate from the cardboard body, allowing the cardboard body to stay on the top of the worktable 1. This allows time for related gluing and assembly before the next contact. Under the reciprocating motion of the pusher plate 10, the cardboard body can stop and pass through each gluing robot arm 5 and the area where related processing flows are located in sequence without repeated start and stop. This extends the service life of the stepper motor 6 to a certain extent. In addition, the pusher plates 10 on both sides can contact the concave surface reserved at the rear of the cardboard body to prevent the cardboard body from tilting during the process of pushing the cardboard body to move. This prevents the gluing and assembly positions from being misaligned, which would cause the cardboard to be unable to be folded and formed normally.
[0040] Please see the appendix Figure 2 - Appendix Figure 4 Assembly mechanism 2 is located on both sides inside the workbench 1 and is used to assemble cardboard boxes;
[0041] The assembly mechanism 2 includes a movable plate 201. The outer side of the movable plate 201 is set inside the protective cover 4. The four corners of the bottom end of the movable plate 201 are fixedly connected to the upright plates 202. The bottom ends of the multiple upright plates 202 are fixedly connected to the toothed plates 203. The multiple toothed plates 203 are all meshed with incomplete gears 204. The middle part of the incomplete gears 204 is fixedly connected to the outer side of the output end of the stepper motor 6.
[0042] The stepper motor 6 can rotate the fixed plate 7 while simultaneously rotating the incomplete gear 204. Since the incomplete gear 204 only has some protruding teeth on its outer side, it can mesh with the protruding teeth on the front and rear sides of the gear plate 203 in sequence when it rotates. This allows the gear plate 203 to perform vertical reciprocating linear motion. Furthermore, under the transmission of the vertical plate 202, the movable plate 201 can perform vertical reciprocating motion. This achieves the purpose of converting part of the rotation output by the stepper motor 6 into linear motion, so that subsequent related actions can obtain power without the need for an additional power source, thus saving energy and making full use of the torque output by the stepper motor 6.
[0043] Please see the appendix Figure 2 - Appendix Figure 4 Multiple toothed plates 203 are slidably connected to limit plates 216 at their front and rear ends. The bottom ends of multiple limit plates 216 are fixedly connected to the bottom of the workbench 1. Multiple incomplete gears 204 are rotatably connected to U-shaped brackets 217 on the outer side away from the fixed plate 7. The ends of the U-shaped brackets 217 away from the incomplete gears 204 are respectively fixedly connected to the front and rear parts of both sides of the workbench 1. The ends of the fixed plates 7 on both sides are rotatably connected to support frames 218. The front and rear parts of the ends of the support frames 218 on both sides are respectively fixedly connected to the ends of the limit plates 216 on both sides. The top four corners of the movable plate 201 are fixedly connected to guide rods 219. The tops of multiple guide rods 219 penetrate the protective cover 4.
[0044] The toothed plate 203 can be limited by the limiting plate 216 to prevent it from tilting during movement and affecting the normal movement of the movable plate 201. The U-shaped bracket 217 can support the incomplete gear 204, thereby preventing the stepper motor 6 from breaking due to excessive force. At the same time, the fixed plate 7 can be restricted by the support frame 218 in conjunction with the limiting plate 216 to prevent the fixed plate 7 from swaying horizontally when under force. In addition, the guide rod 219 can further improve the stability of the movable plate 201 during movement.
[0045] Please see the appendix Figure 5 - Appendix Figure 8The movable plate 201 has fixed plates 205 fixedly connected to both the front and rear sides of its bottom end. A rotating plate 206 is rotatably connected to one side of the bottom end of each of the fixed plates 205. A slider 207 is rotatably connected to the bottom end of each rotating plate 206. A U-shaped plate 208 is slidably connected to the upper part of the slider 207 near the fixed plate 205. Support plates 209 are fixedly connected to the bottom of the front and rear ends of the slider 207. Springs 210 are fixedly connected to both sides of the top of each support plate 209. The top of 210 is fixedly connected to the bottom of the front and rear U-shaped plates 208. The front and rear U-shaped plates 208 are fixedly connected to the end of the fixed plate 205. The bottom of the front and rear connecting plates 211 is fixedly connected to the air pressure chamber 212. The bottom of the front and rear air pressure chambers 212 is fixedly connected to multiple suction cups 213. The end of the front and rear connecting plates 211 away from the U-shaped plate 208 is abutted against the trapezoidal block 214. The front and rear fixed plates 205 are offset from the dispensing robot arm 5.
[0046] The rear fixed plate 205 can apply an upward force to the rotating plate 206 when the movable plate 201 moves upward. Since the length of the rotating plate 206 is fixed and its bottom is connected to the slider 207, the rotating plate 206 can rotate, causing the slider 207 to move closer to the fixed plate 205. This allows the U-shaped plate 208 to move the connecting plate 211 synchronously. After the movable plate 201 moves upward a certain distance, the connecting plate 211 can move the air chamber 212 and multiple suction cups 213. The movable plate 201 moves to contact the trapezoidal block 214, and under the action of the inclined surface of the trapezoidal block 214, the connecting plate 211 can overcome the elastic force of the spring 210 and move down along the inclined surface. This allows the air chamber 212 to drive the suction cup 213 to contact the side cardboard placed in the area where the rear trapezoidal block 214 is located. At the same time, during the downward movement of the air chamber 212, the air inside the suction cup 213 can be squeezed out, so that the suction cup 213 can be adsorbed onto the surface of the side cardboard under the action of external air pressure. As the movable plate 201 moves down, the rotating plate 211... 06 can rotate in the opposite direction and drive the U-shaped plate 208, connecting plate 211, air chamber 212, suction cup 213 and side cardboard back through slider 207. This achieves the purpose of actively grabbing and transferring the side cardboard during the movement of the cardboard body. There is no need to use an additional controller for position adjustment or to carry out complicated debugging work before formal production. Moreover, the linkage between various mechanical structures can reduce the use of power source, further reducing the number of maintenance and difficulty. Similarly, when the side cardboard is assembled and the cardboard body moves to the front fixed plate 205 under the push of push plate 10, the front rotating plate 206 can repeat the above steps to complete the grabbing of the inner liner cardboard. In addition, the staggered setting of fixed plate 205 and glue dispensing robot arm 5 ensures that the corresponding glue application process can be completed before the assembly or forming process to avoid the cardboard from loosening again after assembly or forming. The spring 210 can drive the side cardboard or inner liner cardboard to move upward after the connecting plate 211 separates from the trapezoidal block 214 to avoid collision with push plate 10 during the transfer process.
[0047] Please see the appendix Figure 2 Appendix Figure 5 and attached Figure 7 The bottom ends of the front and rear sliders 207 are slidably connected to the top of the worktable 1. The front and rear U-shaped plates 208 have guide rods 220 running through their front and rear sides. The bottom ends of the guide rods 220 are fixedly connected to the top of the support plate 209. Multiple springs 210 are wrapped around the outside of the guide rods 220. The top of the front and rear U-shaped plates 208 is fixedly connected to the side of the fixed plate 205. The bottom ends of the front and rear U-shaped plates 221 are fixedly connected to the top of the connecting plate 211. The front and rear trapezoidal blocks 214 are fixedly connected to the side of the front and rear trapezoidal blocks 214 away from the connecting plate 211. The bottom ends of the front and rear fixed frames 215 are fixedly connected to the top of the worktable 1.
[0048] The movement direction of the slider 207 can be restricted by the worktable 1 to prevent the slider 207 from deflecting when it moves under force. The guide rod 220 can limit the U-shaped plate 208 to ensure that the U-shaped plate 208 does not deflect. This ensures that multiple suction cups 213 can contact the side cardboard or inner lining cardboard at the same time. The spring 210 wrapped around the outside of the guide rod 220 can prevent them from interfering with each other when they move. At the same time, the U-shaped plate 221 can improve the reliability of the connection between the U-shaped plate 208 and the connecting plate 211. In addition, the fixing bracket 215 can fix the trapezoidal block 214 to prevent the trapezoidal block 214 from being displaced when it is subjected to the action of the connecting plate 211.
[0049] Please see the appendix Figure 8 Both the front and rear connecting plates 211 have through slots 222 on the side away from the U-shaped plate 208. Each through slot 222 has a baffle 223 inside. A pressure plate 224 is fixedly connected to the middle of each baffle 223. A connecting plate 225 is fixedly connected to the bottom of each pressure plate 224. A spring 226 is fixedly connected to the bottom of each connecting plate 225 near the slider 207. The bottom of each spring 226 is fixedly connected to the bottom of the air chamber 212. Multiple limiting cylinders 227 are fixedly connected to the bottom of the air chamber 212 on the side away from the slider 207. Hollow blocks 228 are slidably connected inside the multiple limiting cylinders 227. Multiple arc-shaped ventilation slots 229 are opened on the outer side of the top of the multiple hollow blocks 228. Connecting rods 230 are fixedly connected to the middle of the top of the multiple hollow blocks 228. The top of the connecting rods 230 passes through the limiting cylinders 227 and is fixedly connected to the bottom of the connecting plate 225. The multiple limiting cylinders 227 are all facing the suction cup 213.
[0050] Spring 226 pushes connecting plate 225 upward, which in turn causes pressure plate 224 to move baffle 223 upward, blocking the through slot 222 and preventing outside air from entering the air chamber 212 through the through slot 222. Simultaneously, when connecting plate 225 moves upward, connecting rod 230 moves hollow block 228 upward until it is in contact with the top of limiting cylinder 227. At this time, the evenly distributed arc-shaped ventilation slots 229 on the top of hollow block 228 are blocked by limiting cylinder 227, completely isolating the air chamber 212 from the outside air. This ensures that when suction cup 213 contacts the side cardboard or inner lining cardboard, causing some air inside suction cup 213 and limiting cylinder 227 to be squeezed out, air inside air chamber 212 will not enter suction cup 213, thus preventing the side cardboard or inner lining cardboard from falling off the bottom of suction cup 213. After the linerboard and the cardboard body are assembled, applying pressure to the pressure plate 224 causes the connecting plate 225 to move down and compress the spring 226. At this time, the baffle 223 can leave the inside of the through groove 222, allowing outside air to enter the air pressure chamber 212. At the same time, the connecting rod 230 can drive the hollow block 228 to move down, so the limiting cylinder 227 no longer blocks the arc-shaped ventilation groove 229. Outside air can further pass through the inside of the air pressure chamber 212, through the arc-shaped ventilation groove 229 and the hollow block 228, and enter the inside of the suction cup 213. Thus, when the internal and external air pressures are consistent, the suction cup 213 no longer adheres to the surface of the side cardboard or the inner linerboard, achieving the purpose of preventing the side cardboard or the inner linerboard from falling off during the gripping process and from releasing itself after assembly. In addition, the limiting cylinder 227 facing the suction cup 213 can avoid misalignment and affect the normal adjustment of the internal air pressure of the suction cup 213.
[0051] Please see the appendix Figure 1 and attached Figure 5 The front and rear fixed plates 205 are both fixedly connected to the middle of the bottom of the plate 205. The front and rear fixed plates 231 are both fixedly connected to the side of the plate 206. The front and rear fixed plates 231 are both fixedly connected to the side of the plate 206. The front end of the movable plate 201 is fixedly connected to the connecting frame 233. The bottom end of the connecting frame 233 is fixedly connected to the second pressure block 234.
[0052] The pressure column 231 applies pressure to the connecting plate 211, which drives the side cardboard or inner liner cardboard back, when the movable plate 201 moves down. This causes the spring 210 to contract under force, making the side cardboard or inner liner cardboard contact the glued cardboard body to achieve self-pressing. The pressure block 232 applies pressure to the pressure plate 224 during pressing by compressing the cardboard body, side cardboard, or inner liner cardboard, so that the suction cup 213 no longer performs its gripping function, thus preparing for the next round of gripping. In addition, the connecting frame 233 allows the pressure block 234 to also move down with the movable plate 201, thereby cooperating with the subsequent processing to complete the folding and forming of the cardboard box.
[0053] Please see the appendix Figure 1 Appendix Figure 9 and attached Figure 10 Folding mechanism 3, which is located at the front end of workbench 1, is used to fold the cardboard box into shape;
[0054] Folding mechanism 3 includes a folding table 301, the rear end of which is fixedly connected to the front end of workbench 1. A second support plate 302 is fixedly connected inside the folding table 301. Limiting rods 303 are fixedly connected to both sides of the top of the second support plate 302. A horizontal plate 304 is fixedly connected to the top of the limiting rods 303. A hydraulic rod 305 is fixedly connected to the middle of the top of the second support plate 302. A horizontal plate 306 is fixedly connected to the output end of the hydraulic rod 305. Limiting rods 307 are fixedly connected to both sides of the top of the second horizontal plate 306. T-shaped plates 308 are slidably connected to the outer sides of the tops of the two limiting rods 307. Folding plates are fixedly connected to the tops of the two T-shaped plates 308. The top and front sides of the folding board 309 on both sides are slidably connected to irregularly shaped plates 310. The top and front sides of the folding table 301 are fixedly connected to inclined plates 311. The outer sides of the limit rods 307 on both sides are slidably connected to counterweights 313. The front and rear ends of the counterweights 313 on both sides are rotatably connected to rotating plates 314. The top of the multiple rotating plates 314 is rotatably connected to trapezoidal blocks 315. The top of the trapezoidal blocks 315 is slidably connected to the front and rear sides of the bottom of the folding board 309 on both sides. The bottom of the multiple trapezoidal blocks 315 is rotatably connected to rotating plates 316. The bottom of the multiple rotating plates 316 is rotatably connected to the front and rear sides of the top of the horizontal plate 306 on both sides.
[0055] The horizontal plate 304 is supported by the support plate 2 302 and the limiting rod 303 to ensure that the horizontal plate 304 will not shift and affect the folding shape of the folding box. At the same time, the weight of the counterweight 313 can pull the rotating plate 2 314 to bring the front and rear trapezoidal blocks 2 315 closer together. The supporting force applied to the trapezoidal blocks 2 315 by the rotating plate 316 can be decomposed into vertical and horizontal thrusts. Since the angles of the rotating plate 316 and the rotating plate 2 314 are different, the horizontal thrust of the rotating plate 316 can be reduced by the horizontal pulling force obtained by the weight of the counterweight 313. The counterweights cancel each other out, allowing trapezoidal block 2 315 to maintain balance under the action of counterweight 313, rotating plate 316, and its own weight. After the cardboard is assembled and glued by the front dispensing robot arm 5, it moves to the surface of horizontal plate 1 304 under the action of push plate 10 and is pressed by pressure block 234. Then, hydraulic rod 305 is activated, allowing horizontal plate 2 306 to move its top structure upward. The upward thrust can then be transmitted to folding plate 1 309 through trapezoidal block 2 315. The upward movement of folding plate 1 309 pushes the side cardboard to rotate 90 degrees along the indentation and then stick to both sides of pressure block 234. Simultaneously, after the irregular plate 310 contacts the bottom inclined surface of the inclined plate 311, the two irregular plates 310 can move a certain distance along the folding cardboard 309 under the action of the inclined surface, so as to apply a pushing force to the front and rear parts of the side cardboard and make the front and rear parts of the side cardboard rotate along the indentation and approach the front and rear ends of the pressure block 234, thus achieving the purpose of completing the side folding and forming of the carton. The action is stable and reliable. When the folding cardboard 309 moves up to contact the bottom plane of the inclined plate 311, the folding cardboard 309 no longer moves. As the thrust of the hydraulic rod 305 increases, the trapezoidal block 315 is subjected to a horizontal thrust from the rotating plate 316. The horizontal pulling force provided by the counterweight 313 can be gradually increased, so the front and rear trapezoidal blocks 315 can move away from each other and the counterweight 313 can be pulled up along the limiting rod 307 by the rotating plate 314. The trapezoidal blocks 315 can provide power for the subsequent folding of the carton in the front and back directions. As the horizontal plate 306 moves up, the limiting rod 307 connected to it can move along the corresponding hole inside the T-shaped plate 308 to avoid interfering with the movement of the trapezoidal blocks 315 and the rotating plate 316 after being subjected to force. At the same time, the stability of the folding board 309 can be further improved by the limiting rod 307 and the T-shaped plate 308.
[0056] Please see the appendix Figure 9 and attached Figure 10The top of the horizontal plate 304 is flush with the top of the folding table 301. The two sides of the horizontal plate 306 are slidably connected to the outside of the limiting rod 303. The internal parts of the multiple irregular plates 310 are slidably connected to the limiting frame 312. The bottom of the multiple limiting frames 312 is fixedly connected to the top of the folding plate 309. The multiple inclined plates 311 are directly opposite the irregular plates 310. The internal parts of the multiple trapezoidal blocks 315 are all connected to the limiting plate 320. The front and rear limiting plates 320 are fixedly connected to the front and rear ends of the T-shaped plate 308 respectively.
[0057] The horizontal plate 304 is flush with the folding table 301 to prevent interference with the movement of the cardboard. The horizontal plate 306 moves along the limiting rod 303 to improve its stability during movement. At the same time, the limiting frame 312 can restrict the irregular plate 310 to prevent it from shaking under force. The inclined plate 311 is directly opposite the irregular plate 310 to avoid misalignment that would affect normal movement. In addition, the limiting plate 320 can support the trapezoidal block 315 to prevent it from tilting during movement and causing the folding cardboard 309 to shake.
[0058] Please see the appendix Figure 9 The top and front and rear sides of the horizontal plate 306 are fixedly connected to the limit rod 317. The outer sides of the limit rod 317 are slidably connected to the folding plate 318. The front and rear folding plate 318 are fixedly connected to the trapezoidal block 319 on both sides.
[0059] Trapezoidal block 319 can drive folding cardboard 218 to move upward along limiting rod 317 when trapezoidal block 215 approaches, through their contacting inclined surfaces. Then, folding cardboard 218 can be used to fold the front and rear parts of the cardboard box. Furthermore, when the cardboard body, inner lining cardboard and pressing block 234 are attached to the front and rear ends, the cardboard body and inner lining cardboard are glued by the glued part of the front glue dispensing robot arm 5 and the side cardboard are attached to the front and rear ends of pressing block 234 to complete the overall folding and fixing of the cardboard box without manual intervention.
