Description

Technical Field

[0001] The utility model relates to the technical field of folding devices, in particular to a folding device for carton production. Background Art

[0002] Cartons are containers made of paper pulp, usually used for packaging, storing and transporting items. They can be manufactured in different sizes, shapes and thicknesses to suit a variety of needs. Cartons are lightweight, environmentally friendly and relatively low-cost, so they are widely used in business and daily life. In the process of carton production, semi-finished cardboard needs to be grooved and crimped. After these two steps, the cardboard will eventually be folded near the crimping line. The common folding process requires manual folding, which is labor-intensive.

[0003] A Chinese utility model patent with publication number CN220864877U discloses a rapid folding device for box production, including a transport mechanism, a folding mechanism is arranged on one side of the transport mechanism, the folding mechanism includes a support frame, a placing plate 1 is fixedly installed on one side of the top of the support frame, a limiting plate is fixedly connected to one side of the top of the placing plate 1, a placing plate 2 is fixedly installed on the other side of the top of the support frame, a slope is provided on the side of the placing plate 2 away from the placing plate 1, a through opening is provided in the middle of the bottom of the slope of the placing plate 2, springs are fixedly installed on both sides of the top of the support frame, the tops of the springs on both sides are fixedly connected with lifting plates, and the two sides of the lifting plates are slidably connected to the support frame.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device folds the cardboard through the pressure plate that moves up and down. When the staff needs to take out the cardboard, the staff needs to pull the slide plate to collect the cardboard. However, in actual operation, since the slide plate is slidably connected to the lifting plate, when the pressure plate is pressed down, the cardboard is easily displaced in the horizontal direction under the action of the slide plate, which easily leads to a high defective rate, which is not conducive to improving the user experience of the staff. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a folding device for carton production.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a folding device for carton production, comprising a support frame, a placing plate installed on the upper surface of the support frame, and a folding device arranged on the placing plate, the upper surface of the placing plate is provided with a slide groove, the inner bottom wall of the slide groove is provided with a support spring, a lifting plate is slidably arranged in the slide groove, the lifting plate and the support spring are fixed to each other, a moving groove is provided on the upper surface of the lifting plate, a moving rod is slidably arranged in the moving groove, a slide plate is fixed on the upper surface of the moving rod, and a limiting component for limiting the slide plate is provided on the slide plate.

[0007] By adopting the above technical solution, when the staff needs to fold the cardboard, the staff needs to place the cardboard on the slide plate and start the folding device, so that the pressing plate on the folding device can move downward and press against the central area of ​​the cardboard, and then the cardboard and the lifting plate move downward under the action of the pressing plate, so that the two ends of the cardboard are folded. Afterwards, the staff needs to reset the folding device and close the limit assembly, so that the slide plate can be slid, thereby reducing the difficulty of the staff to take out the cardboard.

[0008] Furthermore, limiting grooves are provided on both sides of the bottom surface of the slide plate, and the limiting assembly includes a limiting rod slidably arranged in the limiting groove, a limiting spring with one end fixed to the upper surface of the limiting rod, and a connecting rope with one end fixed to the upper surface of the limiting rod, the other end of the limiting spring is fixed to the inner top wall of the limiting groove, and limiting holes matching the limiting rod are provided on both sides of the upper surface of the lifting plate.

[0009] By adopting the above technical solution, when the staff connects the moving rod and the moving groove, the limit rod moves completely into the limit groove. Then, when the staff pushes the limit, the limit groove gradually approaches the limit hole and finally faces the limit hole. At this time, the limit rod is connected to the limit hole under the action of the limit spring, so that the two limit rods limit the slide plate, thereby reducing the probability of relative displacement between the slide plate and the lifting plate at this time, thereby improving the stability of the device.

[0010] Furthermore, an arc-shaped groove is provided on the side wall of the slide plate, a rotating rod is rotatably arranged in the arc-shaped groove, and one end of the two connecting ropes away from the limiting rod is fixed to the rotating rod.

[0011] By adopting the above technical solution, when the staff needs to take down the folded cardboard, in order to reduce the difficulty of the staff's operation, the staff needs to slide the slide plate. At this time, the staff needs to rotate the rotating rod, so that one end of the two connecting ropes can move with the rotating rod at the same time, so that the two limit rods move upward under the action of the two connecting ropes respectively, and then the limit rods return to the limit groove. At this time, the staff only needs to pull the slide plate to separate the slide plate from the lifting plate, thereby improving the staff's user experience.

[0012] Furthermore, a first inclined surface is formed on the bottom surfaces of the two limiting rods and the side walls thereof away from the arc-shaped groove.

[0013] By adopting the above technical solution, when the staff pushes the slide plate, the limit rod automatically moves into the limit groove under the joint action of the first inclined surface and the slide plate, and the staff does not need to manually slide the limit rod, thereby reducing the operating difficulty of the staff.

[0014] Furthermore, a C-shaped groove is provided on the inner wall of the arc-shaped groove, and a blocking rod for blocking the rotating rod is slidably provided in the C-shaped groove.

[0015] Furthermore, an L-shaped rod is fixed on the side wall of the baffle rod, a return spring is fixed on the side wall of the L-shaped rod away from the rotating rod, the other end of the return spring is fixed to the inner wall of the C-shaped groove, and a second inclined surface is provided on the upper surface of the baffle rod.

[0016] By adopting the above technical solution, when the staff rotates the rotating rod, the blocking rod is completely moved into the C-shaped groove under the joint action of the first inclined surface and the rotating rod. Subsequently, when the rotating rod passes over the blocking rod, the blocking rod quickly resets and blocks the rotating rod, thereby reducing the probability of the rotating rod automatically resetting at this time, and the staff can directly release the rotating rod, thereby reducing the difficulty of the staff's operation. Furthermore, when the staff needs to reset the rotating rod, the staff only needs to press the L-shaped rod to make the blocking rod move with the L-shaped rod, and then the blocking rod is completely moved into the C-shaped groove, so that the rotating rod is reset under the action of the connecting rope.

[0017] Furthermore, a stabilizing rod is fixed to the bottom surface of the lifting plate, and the stabilizing rod is slidably connected to the inner bottom wall of the sliding groove.

[0018] By adopting the above technical solution, the stability of the lifting plate is improved, thereby reducing the probability of one side of the lifting plate tilting when the lifting plate moves up and down.

[0019] Furthermore, a silicone sheet for reducing pain is provided on the side wall of the L-shaped rod away from the return spring.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to fold the cardboard, the staff needs to place the cardboard on the slide and start the folding device, so that the pressing plate on the folding device moves downward and presses against the center area of ​​the cardboard, and then the cardboard and the lifting plate move downward under the action of the pressing plate, so that the two ends of the cardboard are folded. Afterwards, the staff needs to reset the folding device and close the limit assembly, and then slide the slide, thereby reducing the difficulty of the staff to take out the cardboard;

[0022] 2. In this application, when the staff connects the moving rod and the moving slot, the limit rod moves completely into the limit slot. Then, when the staff pushes the limit, the limit slot gradually approaches the limit hole and finally faces the limit hole. At this time, the limit rod is connected to the limit hole under the action of the limit spring, so that the two limit rods limit the slide plate, thereby reducing the probability of relative displacement between the slide plate and the lifting plate, thereby improving the stability of the device;

[0023] 3. In the present application, when the staff member rotates the rotating rod, the blocking rod moves completely into the C-shaped groove under the joint action of the first inclined surface and the rotating rod. Subsequently, when the rotating rod passes over the blocking rod, the blocking rod quickly resets and blocks the rotating rod, thereby reducing the probability of the rotating rod automatically resetting at this time, and the staff member can directly release the rotating rod, thereby reducing the difficulty of the staff member's operation. Furthermore, when the staff member needs to reset the rotating rod, the staff member only needs to press the L-shaped rod to make the blocking rod move with the L-shaped rod, and then the blocking rod moves completely into the C-shaped groove, so that the rotating rod is reset under the action of the connecting rope.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0031] like Figure 1-5 As shown, the embodiment of the present application discloses a folding device for carton production, including a support frame 1, a placement plate 11, a folding device 2, a support spring 3, a lifting plate 31, a moving rod 41, a slide plate 5, a limit assembly 6, a rotating rod 71, a blocking rod 81, an L-shaped rod 82, a reset spring 83, a stabilizing rod 85 and a silicone sheet 9. The placement plate 11 is mounted on the upper surface of the support frame 1, and a slide groove 21 is provided on the upper surface of the placement plate 11. The folding device 2 is arranged on the placement plate 11 and is used to fold the cardboard. One end of the support spring 3 is arranged on the inner bottom wall of the slide groove 21, the lifting plate 31 is a rectangular plate-shaped structure, the lifting plate 31 is slidably arranged in the slide groove 21, and the lifting plate 31 and the support spring 3 are fixed to each other. A moving groove 4 is provided on the upper surface of the lifting plate 31, and the moving rod 41 is a rectangular rod-shaped structure, and the moving rod 41 is slidably arranged in the moving groove 4. The slide plate 5 is a rectangular plate-shaped structure, and the slide plate 5 is fixed to the upper surface of the moving rod 41.

[0032] Limiting grooves 51 are provided on both sides of the bottom surface of the slide plate 5. The limiting assembly 6 is arranged on the slide plate 5 for limiting the slide plate 5. The limiting assembly 6 comprises a limiting rod 61, a limiting spring 62 and a connecting rope 63. The limiting rod 61 is a rectangular rod-shaped structure, and the limiting rod 61 is slidably arranged in the limiting groove 51. One end of the limiting spring 62 is fixed to the upper surface of the limiting rod 61, and the other end of the limiting spring 62 is fixed to the inner top wall of the limiting groove 51. One end of the connecting rope 63 is fixed to the upper surface of the limiting rod 61, and limiting holes 64 matching the limiting rod 61 are provided on both sides of the upper surface of the lifting plate 31.

[0033] When the staff connects the moving rod 41 and the moving slot 4, the limiting rod 61 completely moves into the limiting slot 51. Then, when the staff pushes the limit, the limiting slot 51 gradually approaches the limiting hole 64 and finally faces the limiting hole 64. At this time, the limiting rod 61 is connected to the limiting hole 64 under the action of the limiting spring 62, so that the two limiting rods 61 limit the slide plate 5, thereby reducing the probability of relative displacement between the slide plate 5 and the lifting plate 31 at this time, thereby improving the stability of the device.

[0034] An arc groove 7 is formed on the side wall of the slide plate 5 . The rotating rod 71 is a rod-shaped structure. The rotating rod 71 is rotatably disposed in the arc groove 7 . One end of the two connecting ropes 63 away from the limiting rod 61 is fixed to the rotating rod 71 .

[0035] When the staff needs to take off the folded cardboard, in order to reduce the difficulty of operation, the staff needs to slide the slide plate 5. At this time, the staff needs to rotate the rotating rod 71, so that one end of the two connecting ropes 63 can move with the rotating rod 71 at the same time, so that the two limit rods 61 move upward under the action of the two connecting ropes 63, and then the limit rods 61 return to the limit groove 51. At this time, the staff only needs to pull the slide plate 5 to separate the slide plate 5 from the lifting plate 31, thereby improving the staff's use experience.

[0036] In order to reduce the difficulty of operation for the staff, the bottom surfaces of the two limit rods 61 and the side walls away from the arc groove 7 are both provided with first inclined surfaces 72. When the staff pushes the slide plate 5, the limit rods 61 automatically move into the limit groove 51 under the joint action of the first inclined surfaces 72 and the slide plate 5, and the staff does not need to manually slide the limit rods 61, thereby reducing the difficulty of operation for the staff.

[0037] A C-shaped groove 8 is formed on the inner wall of the arc groove 7 . The blocking rod 81 is a rod-shaped structure. The blocking rod 81 is slidably disposed in the C-shaped groove 8 to block the rotating rod 71 .

[0038] The L-shaped rod 82 is a rod-shaped structure with an L-shaped cross section, and the L-shaped rod 82 is fixed to the side wall of the blocking rod 81.

[0039] When the staff member rotates the rotating rod 71, the blocking rod 81 is completely moved into the C-shaped groove 8 under the joint action of the first inclined surface 72 and the rotating rod 71. Subsequently, when the rotating rod 71 passes over the blocking rod 81, the blocking rod 81 quickly resets and blocks the rotating rod 71, thereby reducing the probability of the rotating rod 71 automatically resetting at this time, and the staff member can directly release the rotating rod 71, thereby reducing the difficulty of the staff member's operation. Further, when the staff member needs to reset the rotating rod 71, the staff member only needs to press the L-shaped rod 82 to make the blocking rod 81 move with the L-shaped rod 82, and then the blocking rod 81 is completely moved into the C-shaped groove 8, so that the rotating rod 71 is reset under the action of the connecting rope 63.

[0040] The stabilizing rod 85 is a round rod structure, fixed to the bottom surface of the lifting plate 31, and slidably connected to the inner bottom wall of the slide groove 21. The stabilizing rod 85 improves the stability of the lifting plate 31, thereby reducing the probability of one side of the lifting plate 31 tilting when the lifting plate 31 moves up and down.

[0041] In order to improve the user experience of the staff, a silicone sheet 9 for reducing pain is provided on the side wall of the L-shaped rod 82 away from the return spring 83.

[0042] The working principle of a folding device 2 for carton production in this embodiment is as follows: when the staff needs to fold the cardboard, the staff needs to place the cardboard on the slide plate 5 and start the folding device 2, so that the pressing plate on the folding device 2 moves downward and presses against the central area of ​​the cardboard, and then the cardboard and the lifting plate 31 move downward under the action of the pressing plate, so that the two ends of the cardboard are folded. Subsequently, the staff needs to reset the folding device 2 and close the limit assembly 6, so that the slide plate 5 can be slid, thereby reducing the difficulty of the staff to take out the cardboard.
