Description

Technical Field

[0001] This utility model relates to a packaging box flat plate stacking adjustment device. Background Technology

[0002] A packaging box is a box used to package and store products. During the processing of packaging boxes, the cardboard or plastic sheet of the packaging box needs to be cut or creasing. The unprocessed cardboard or plastic sheet is collectively referred to as the packaging box flat sheet. When cutting or creasing, the packaging box flat sheets usually need to be arranged and placed for subsequent creasing or cutting. However, packaging box flat sheets placed manually or automatically unloaded on an assembly line will have problems such as misalignment and displacement. Moreover, manual neat placement is not only time-consuming and labor-intensive, but the cardboard or plastic sheet after placement is also easily affected by the external environment, resulting in misalignment or displacement. In particular, lightweight PET plastic sheets are more prone to being blown away by external air currents, making it difficult to stably and effectively carry out subsequent automated creasing and cutting processing of cardboard or plastic sheets. Utility Model Content

[0003] This utility model mainly solves the technical problems existing in the prior art, thereby providing a packaging box stacking adjustment device that facilitates the operator to adjust and place packaging box flat panels, and can centrally restrict and adjust packaging box flat panels of different specifications.

[0004] This utility model is a packaging box flat stacking adjustment device, including a workbench and two sets of first and second guardrails movably connected to the upper surface of the workbench. An active gear is movably connected inside the workbench, and a linkage mechanism is connected to the outside of the active gear. A movable mechanism for driving the first and second guardrails to move is connected to the side of the linkage mechanism. The linkage mechanism includes a driven gear meshing with the active gear, a core rod connected behind the driven gear, and a shaft seat movably connected to the front end of the core rod. The movable mechanism includes a screw that meshes with the core rod, and a nut seat threaded to the center of the screw for controlling the movement of the first or second guardrail. A cylinder for controlling the meshing of the driven gear and the active gear is connected inside the workbench, and a motor for driving the active gear to rotate is connected below the workbench.

[0005] Preferably, there are two of each of the first and second fences, located around the workbench. Each of the first and second fences has a movable mechanism below it, and the movable mechanism and the linkage mechanism cooperate with each other, so that the linkage mechanism can drive the movable mechanism to rotate. In turn, the movable mechanism controls the corresponding connected first and second fences to move closer or further apart, so that the first and second fences can surround and center the packaging box flat plate on the workbench surface.

[0006] Preferably, a straight shaft is connected between the driven tooth and the core rod, and the bearing seat is movably connected to the outside of the straight shaft. A connecting rod connected to the piston rod of the cylinder is connected to the side of the bearing seat, so that the cylinder can drive the straight shaft to move through the connecting rod and the bearing seat, and then drive the driven tooth to move and adjust through the straight shaft.

[0007] Preferably, the screw has a core hole that mates with the core rod inside. One end of the screw passes through the worktable and is connected to a turntable. The other end of the screw near the driven tooth is connected to a retaining ring, so that the core rod can be inserted into the screw through the core hole and the core rod and the screw can cooperate with each other, so that the core rod can drive the screw to rotate. At the same time, the turntable can also drive the screw to rotate. The retaining ring is provided to limit the end of the screw.

[0008] Preferably, the core rod and the core hole are in a sliding fit and are both polygonal structures, so that the core rod can synchronously drive the screw to rotate through the fit between the core rod and the core hole.

[0009] Preferably, the core rod and core hole can be triangular, quadrilateral, pentagonal or hexagonal structures, so that the core rod can drive the screw to rotate through the cooperation with the core hole, and the core rod can be embedded in the core hole placed inside the screw and slide inside the core hole.

[0010] Preferably, a support rod for connecting the first fence or the second fence is connected above the nut seat, and a bearing is connected between the shaft seat and the straight shaft, so that the movement of the nut seat can synchronously drive the first fence or the second fence connected to it to move accordingly, and the bearing arrangement facilitates the rotation of the straight shaft inside the shaft seat.

[0011] Preferably, the upper surface of the workbench is provided with waist grooves and sliding grooves. There are four waist grooves, and the support rod passes through the waist groove and is connected to the first or second guardrail. Sliding grooves are provided on both sides of the waist grooves. Sliding blocks connected to the first or second guardrail are slidably connected inside the sliding grooves. The first guardrail has slots on both sides, and the second guardrail has railings on both sides that cooperate with the slots, so that the support rod can be connected to the first or second guardrail through the waist grooves. At the same time, the sliding blocks connected below the first or second guardrail can be slidably connected in the sliding grooves on the surface of the workbench to increase the stability of the first or second guardrail when sliding. The slots and railings facilitate the staggering of the first and second guardrails, so as to increase the interception and limitation of the packaging box flat plate placed on the workbench by the first and second guardrails, and maximize the contact area of ​​the first and second guardrails with the packaging box flat plate on the workbench.

[0012] Preferably, the cylinder is a standard cylinder or a bidirectional cylinder, the motor is a geared motor or a servo motor, and a rotating shaft connected to the output shaft of the motor is connected below the driving gear. When the cylinder is a standard cylinder, a cylinder is connected to the side of each shaft seat to drive the driven gear to move. When the cylinder is a bidirectional cylinder, two opposing shaft seats can be connected simultaneously through the bidirectional cylinder, thereby synchronously driving the two opposing driven gears to move synchronously. The geared motor or servo motor drives the rotating shaft to drive the driving gear to rotate at low speed and high torque.

[0013] The beneficial effects of this utility model are as follows: Due to the mating connection between the core rod and the screw, the rotation of the driven teeth can drive the screw to rotate, causing the nut seat threaded to the center of the screw to move accordingly. The movement of the nut seat drives the first or second guardrail connected to it to slide accordingly. Each of the first or second guardrails on the worktable has a corresponding driven tooth below it, and the driven teeth are distributed and meshed on the outside of the driving teeth. This allows the rotation of the driving teeth to synchronously drive the driven teeth that mesh with them to rotate, enabling the first and second guardrails on the worktable surface to move closer or further apart synchronously. This allows the packaging box flats placed on the worktable to be centered and adjusted by the restriction of the first and second guardrails, avoiding the misalignment that occurs when conventional packaging box flats are stacked. This limitation of the packaging box flats increases the stacking efficiency. The device achieves a neat and orderly effect. The core rod is slidably connected to the core hole in the center of the screw, and the front end of the core rod is connected to a bearing seat. The worktable is connected to a cylinder for driving the bearing seat to move. The cylinder drives the bearing seat and the core rod connected to it to slide, so that the operator can control whether the driven tooth and the driving tooth mesh. By controlling whether the driven tooth and the driving tooth mesh, the operator can adjust whether the driving tooth drives the screw to rotate, and thus reasonably adjust the movement of the nut seat in the center of the screw. This allows the operator to adjust the distance between the first or second guardrail on the worktable surface according to the size of the packaging box flat. The first and second guardrails can reasonably restrict and adjust the packaging paper of various specifications, so that the device can center and restrict the adjustment of packaging box flats of different specifications, ensuring the flatness and neatness of the stacked packaging paper flats.

[0020] like Figures 1 to 4 The illustrated packaging box flat stacking adjustment device includes a workbench 1 and two sets of first railings 241 and second railings 242 movably connected to the upper surface of the workbench 1. An active gear 4 is movably connected inside the workbench 1. A linkage mechanism 3 is connected to the outside of the active gear 4, and a movable mechanism 2 for driving the first railings 241 and second railings 242 is connected to the side of the linkage mechanism 3. The linkage mechanism 3 includes a driven gear 34 meshing with the active gear 4, a core rod 32 connected behind the driven gear 34, and a shaft seat 33 movably connected to the front end of the core rod 32. The movable mechanism 2 includes a screw 21 cooperating with the core rod 32, and a nut seat 23 threaded to the center of the screw 21 for controlling the movement of the first railing 241 or the second railing 242. A cylinder 5 for controlling the meshing of the driven gear 34 and the active gear 4 is connected inside the workbench 1. A motor (not labeled) for driving the active gear 4 to rotate is connected below the workbench 1.

[0021] Two of each of the first fence 241 and the second fence 242 are provided and are located around the workbench 1 respectively. Each of the first fence 241 and the second fence 242 is provided with a movable mechanism 2 below it. The movable mechanism 2 and the linkage mechanism 3 cooperate with each other, so that the linkage mechanism 3 can drive the movable mechanism 2 to rotate. In turn, the movable mechanism 2 controls the corresponding connected first fence 241 and second fence 242 to move closer or further apart, so that the first fence 241 and the second fence 242 surround and center the packaging box flat plate on the surface of the workbench 1.

[0022] A straight shaft 31 is connected between the driven gear 34 and the core rod 32. The bearing seat 33 is movably connected to the outside of the straight shaft 31, and a connecting rod 51 connected to the piston rod of the cylinder 5 is connected to the side of the bearing seat 33, so that the cylinder 5 can drive the straight shaft 31 to move through the connecting rod 51 and the bearing seat 33, and then drive the driven gear 34 to move and adjust through the straight shaft 31.

[0023] The screw 21 has a core hole 22 that mates with the core rod 32. One end of the screw 21 passes through the workbench 1 and is connected to the turntable 25. The other end of the screw 21, near the driven tooth 34, is connected to a retaining ring 26, so that the core rod 32 can be inserted into the screw 21 through the core hole 22 and the core rod 32 and the screw 21 can cooperate with each other, so that the core rod 32 can drive the screw 21 to rotate. At the same time, the turntable 25 can also drive the screw 21 to rotate. The retaining ring 26 is provided to limit the end of the screw 21.

[0024] The core rod 32 and the core hole 22 are in sliding fit and are both polygonal structures, so that the core rod 32 can synchronously drive the screw 21 to rotate through the cooperation of the core rod 32 and the core hole 22.

[0025] The core rod 32 and the core hole 22 can be triangular, quadrilateral, pentagonal or hexagonal structures, so that the core rod 32 can drive the screw 21 to rotate through the cooperation with the core hole 22. At the same time, the core rod 32 can be embedded in the core hole 22 placed inside the screw 21 and slide inside the core hole 22.

[0026] A support rod 24 for connecting the first fence 241 or the second fence 242 is connected above the nut seat 23. A bearing 331 is connected between the shaft seat 33 and the straight shaft 31, so that the movement of the nut seat 23 can synchronously drive the first fence 241 or the second fence 242 connected to it to move accordingly. The bearing 331 facilitates the rotation of the straight shaft 31 inside the shaft seat 33.

[0027] The upper surface of the workbench 1 is provided with waist grooves 11 and sliding grooves 12. Four waist grooves 11 are provided, and a support rod 24 passes through the waist groove 11 and connects to either a first guardrail 241 or a second guardrail 242. Sliding grooves 12 are provided on both sides of each waist groove 11. A slider 121, connected to either the first guardrail 241 or the second guardrail 242, is slidably connected inside each sliding groove 12. The first guardrail 241 has slots 2411 on both sides, and the second guardrail 242 has railings 2421 on both sides that mate with the slots 2411, allowing the support rod 24 to pass through the waist grooves 11 and connect to either the first guardrail 241 or the second guardrail 242. The fences 242 are connected, and the sliders 121 connected below the first fence 241 or the second fence 242 can slide in the grooves 12 on the surface of the workbench 1 to increase the stability of the first fence 241 or the second fence 242 when sliding. The slots 2411 and the railings 2421 facilitate the interlacing of the first fence 241 and the second fence 242, so as to increase the interception and limitation of the packaging box plate placed on the workbench 1 by the first fence 241 and the second fence 242, and maximize the contact area of ​​the first fence 241 and the second fence 242 with the packaging box plate on the workbench 1.

[0028] The cylinder 5 is a standard cylinder or a bidirectional cylinder, and the motor is a geared motor or a servo motor. The drive gear 4 is connected to a rotating shaft (not labeled) connected to the output shaft of the motor. When the cylinder 5 is a standard cylinder, each bearing 33 is connected to a cylinder 5 on its side to drive the driven gear 34 to move. When the cylinder 5 is a bidirectional cylinder, two opposing bearings 33 can be connected simultaneously through the bidirectional cylinder, thereby synchronously driving the two opposing driven gears 34 to move synchronously. The geared motor or servo motor drives the rotating shaft to drive the drive gear 4 to rotate at low speed and high torque.

[0029] This packaging box stacking adjustment device can center and limit the packaging box flats located on the workbench 1. First, the packaging box flats are stacked on the surface of the workbench 1, with the first guardrail 241 and the second guardrail 242 on the perimeter of the workbench 1 respectively. The motor drives the active gear 4 to rotate, causing the active gear 4 to drive the driven gear 34 that meshes with it to rotate. Through the cooperation between the core rod 32 and the screw 21, the driven gear 34 drives the screw 21 to rotate accordingly, allowing the nut seat 23 connected to the center of the screw by the thread 21 to slide. Then, through the support rod 24 connected to the nut seat 23, the first guardrail 241 or the second guardrail 242 slides accordingly, allowing the first guardrail 241 and the second guardrail 242 to limit and center the packaged packaging box flats. When the packaging box flats are of different sizes, only the cylinder 5 needs to be driven to move the bearing seat 33, allowing the bearing seat 3... 3. The core rod 32 connected to it is driven to penetrate into the core hole 22 inside the screw 21, and at the same time, the driven tooth 4 is disengaged from the driving tooth 34. This prevents the rotation of the driving tooth 4 from driving the disengaged driven tooth 34 to rotate, thereby stopping the first fence 241 or the second fence 242 connected to the disengaged driven tooth 34. The operator can then manually drive the corresponding screw 21 of the disengaged driven tooth 34 to rotate directly through the turntable 25 to adjust the movement of the nut seat 23, thereby manually controlling the corresponding movement of the first fence 241 or the second fence 242. Alternatively, the motor can drive the driving tooth 4 to drive the driven tooth 34 and the corresponding first fence 241 or the second fence 242 to slide, so that the first fence 241 and the second fence 242 can effectively wrap and limit the packaging box flats of different sizes to ensure the neatness of the stacked items. Both the driving tooth 4 and the driven tooth 34 are straight bevel gears.

[0030] The beneficial effects of this utility model are as follows: Due to the mating connection between the core rod and the screw, the rotation of the driven teeth can drive the screw to rotate, causing the nut seat threaded to the center of the screw to move accordingly. The movement of the nut seat drives the first or second guardrail connected to it to slide accordingly. Each of the first or second guardrails on the worktable has a corresponding driven tooth below it, and the driven teeth are distributed and meshed on the outside of the driving teeth. This allows the rotation of the driving teeth to synchronously drive the driven teeth that mesh with them to rotate, enabling the first and second guardrails on the worktable surface to move closer or further apart synchronously. This allows the packaging box flats placed on the worktable to be centered and adjusted by the restriction of the first and second guardrails, avoiding the misalignment that occurs when conventional packaging box flats are stacked. This limitation of the packaging box flats increases the stacking efficiency. The device achieves a neat and orderly effect. The core rod is slidably connected to the core hole in the center of the screw, and the front end of the core rod is connected to a bearing seat. The worktable is connected to a cylinder for driving the bearing seat to move. The cylinder drives the bearing seat and the core rod connected to it to slide, so that the operator can control whether the driven tooth and the driving tooth mesh. By controlling whether the driven tooth and the driving tooth mesh, the operator can adjust whether the driving tooth drives the screw to rotate, and thus reasonably adjust the movement of the nut seat in the center of the screw. This allows the operator to adjust the distance between the first or second guardrail on the worktable surface according to the size of the packaging box flat. The first and second guardrails can reasonably restrict and adjust the packaging paper of various specifications, so that the device can center and restrict the adjustment of packaging box flats of different specifications, ensuring the flatness and neatness of the stacked packaging paper flats.

Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
