Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carton slotting, in particular to a packaging carton die-cutting slotting device. Background Art
[0002] Carton die-cutting and slotting refers to a cutting process for the later processing of packaging cartons. The die-cutting process can make packaging cartons or other paper products into die-cutting knife plates according to pre-designed patterns for cutting, so that the shape of the carton is no longer limited to straight edges and right angles. Traditional die-cutting production uses die-cutting knives to combine into die-cutting plates according to the patterns required by product design. Under the action of pressure, printed materials or other plate-like blanks are rolled into the required shape or cut marks. The mark process uses a creasing knife or a creasing die to press out line marks on the sheet through the action of pressure, or uses a rolling wheel to roll out line marks on the sheet, so that the sheet can be bent and formed according to the predetermined position. Usually, the die-cutting and creasing process combines the die-cutting knife and the creasing knife in the same template, and performs die-cutting and creasing processing on the die-cutting machine at the same time.
[0003] An existing packaging carton die-cutting and slotting device uses an automatic feeding device to feed the cardboards to be die-cut and slotted into the die-cutting and slotting machine one by one when feeding the packaging carton die-cutting and slotting. However, since the packaging carton itself is light in weight, when the number of stacked cardboards decreases, the pressure on the bottom layer decreases, and the feeding mechanism will convey multiple pieces of cardboard on the upper layer when conveying the bottom layer of cardboard into the die-cutting and slotting machine, thereby causing the cardboard slotting failure and resulting in waste of cartons.
[0004] For this purpose, a packaging carton die-cutting and slotting device is specially proposed. Utility Model Content
[0005] The purpose of the utility model is to provide a packaging carton die-cutting and slotting device to solve the problems raised in the above-mentioned background technology.

[0014] Compared with the prior art, the utility model provides a packaging carton die-cutting and slotting device, which has the following beneficial effects:
[0015] By setting a base, a pull rod, a pressure plate, a spring, a support plate and a supporting bottom plate, when die-cutting and slotting packaging cartons, the carton to be slotted can be placed on the top of the supporting bottom plate, and then the pull rod is pulled upward to make the two ends of the pull rod slide upward inside the support plate, and at the same time, the springs installed on the outside of the two ends of the pull rod are compressed to increase the height of the pressure plate, so that the bottom end of the pressure plate is pressed on the top of the stacked cartons. At this time, the pull rod is released, and the compressed springs at both ends of the pull rod will rebound to push the pressure plate downward. At this time, the stacked cartons can be pressed on the top of the supporting bottom plate by the pressure of the pressure plate.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Embodiment 1: Two supporting bottom plates 24 are installed on one side of the top of the base 1, a supporting plate 11 is installed on the top of the supporting bottom plate 24, a limiting plate 9 is installed on both sides of the two supporting plates 11, a pull rod 10 is movably installed on the top of the two support plates 11, both ends of the pull rod 10 pass through the top of the support plate 11, springs 22 are installed on the outside of both ends of the pull rod 10, pressure plates 21 are installed on the bottom of both ends of the pull rod 10, and a feeding trough 25 is provided between the limiting plate 9 and the supporting bottom plate 24.
[0023] Specifically, Figure 1 , Figure 2 and Figure 4As shown, when die-cutting and slotting the packaging cartons, the cartons to be slotted can be placed above the supporting bottom plate 24, and then the pull rod 10 is pulled upward to make the two ends of the pull rod 10 slide upward inside the support plate 11, and at the same time, the springs 22 installed on the outside of the two ends of the pull rod 10 are compressed, thereby raising the height of the pressing plate 21, so that the bottom end of the pressing plate 21 is pressed above the stacked cartons. At this time, the pull rod 10 is released, and the compressed springs 22 at both ends of the pull rod 10 will rebound to push the pressing plate 21 downward. At this time, the stacked cartons can be pressed above the supporting bottom plate 24 by the pressing of the pressing plate 21. Limiting plates 9 are installed on both sides of the plate 11, and the two limiting plates 9 can be used to limit the two sides of the stacked cartons. Since a feeding trough 25 is provided between the limiting plates 9 and the supporting bottom plate 24, the feeding trough 25 can ensure that the cartons at the bottom layer are pushed into the die-cutting machine for slotting. When the cartons are fed into the die-cutting and slotting machine one by one, the height of the cardboard stacked above the supporting bottom plate 24 will drop, and the pressing plate 21 can always press the carton board through the spring 22, thereby avoiding the situation where the upper cartons are pulled out during the transportation of the bottom cartons, and avoiding the waste of cartons caused by failed production.
[0024] Embodiment 2: A mounting groove 14 is provided inside the base 1, a screw rod 15 is installed inside the mounting groove 14, a slider 13 is provided on the outer side of the screw rod 15 through a threaded engagement sleeve, the top end of the slider 13 extends out of the mounting groove 14, a second push plate 23 is installed on the top of one side of the slider 13, a motor 12 is installed on one side of the base 1, and the output end of the motor 12 extends into the mounting groove 14 and is connected to one end of the screw rod 15.
[0025] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rotation of the output end of the motor 12 can drive the screw rod 15 to rotate, and the rotation of the screw rod 15 can drive the slider 13 to slide along the installation direction of the screw rod 15, and the movement of the slider 13 can drive the second push plate 23 to move. The movement of the second push plate 23 can push out the bottom layer of cartons stacked on the supporting bottom plate 24. When the bottom layer of cartons has not reached the inside of the die-cutting and slotting machine, the second push plate 23 will be above the supporting bottom plate 24, thereby supporting the bottom of the cartons stacked above the supporting bottom plate 24 to ensure the stability of the stacked cartons.
[0026] Embodiment 3: Four supporting legs 16 are installed at the bottom of the base 1, and the four supporting legs 16 are respectively located at the four corners of the bottom of the base 1, a supporting rod 3 is installed on one side of the top of the base 1, a top plate 5 is installed on the top of the supporting rod 3, a first electric telescopic rod 8 is installed on the top of the top plate 5, and the output end of the first electric telescopic rod 8 passes through the inside of the top plate 5, a die-cutting board 6 is installed at the output end of the first electric telescopic rod 8, a slotting knife 4 is installed at the bottom of the die-cutting board 6, and a supporting slide bar 7 is installed on both sides of the top of the die-cutting board 6, and the two supporting slide bars 7 are installed on the top of the die-cutting board 6. The top of the base 1 slides through the top plate 5, a lower die-cutting groove 2 is installed on the top of the base 1, and the lower die-cutting groove 2 is located directly below the die-cutting plate 6, a discharge port 17 is opened at the bottom of the base 1, and the discharge port 17 passes through the inside of the base 1, and the lower die-cutting groove 2 and the discharge port 17 are used in conjunction with each other, a mounting frame 19 is installed on one side of the top of the base 1, and a second electric telescopic rod 18 is installed on one side of the mounting frame 19, the output end of the second electric telescopic rod 18 passes through the inside of the mounting frame 19, and a first push plate 20 is installed on the output end of the second electric telescopic rod 18.
[0027] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the carton can be transported to the top of the lower die-cutting groove 2 by the conveying of the second push plate 23, and then the die-cutting plate 6 is driven to move downward by the extension of the output end of the first electric telescopic rod 8. Since a slotting knife 4 is installed at the bottom of the die-cutting plate 6, the carton can be die-cut and slotted by extruding the die-cutting plate 6 and the lower die-cutting groove 2. Since the die-cutting groove opened inside the lower die-cutting groove 2 is connected with the inside of the discharge port 17, the waste generated after the carton is slotted and die-cut will slide out through the discharge port 17. By placing a collecting device below the discharge port 17, the waste can be collected uniformly to avoid the waste being scattered all over the ground, thereby ensuring a clean and tidy working environment. After the slotting is completed, the first push plate 20 can be driven to move toward the top of the lower die-cutting groove 2 by the extension of the output end of the second electric telescopic rod 18, thereby pushing the carton with the slotted top of the lower die-cutting groove 2 to the top of the lower die-cutting groove 2, so as to facilitate the processing of subsequent cartons.
[0028] Working principle: When in use, place the carton to be slotted on the top of the supporting bottom plate 24, then pull the pull rod 10 upwards to press the bottom end of the pressing plate 21 on the top of the stacked carton, and the stacked carton can be pressed on the top of the supporting bottom plate 24 by the pressing of the pressing plate 21, and the two sides of the stacked carton can be limited by the two limit plates 9, and then the rotation of the output end of the motor 12 can drive the screw rod 15 to rotate, and the rotation of the screw rod 15 can drive the slider 13 to slide along the installation direction of the screw rod 15, and the movement of the slider 13 can drive the second push plate 23 to move, and the movement of the second push plate 23 can push out the bottom layer of the carton stacked on the supporting bottom plate 24, and push the second push plate 23 to push the bottom layer of the carton stacked on the supporting bottom plate 24. The conveying of the plate 23 can convey the carton to the top of the lower die-cutting groove 2, and then the die-cutting plate 6 is driven to move downward by the extension of the output end of the first electric telescopic rod 8. The carton can be die-cut and slotted by the extrusion of the die-cutting plate 6 and the lower die-cutting groove 2. The waste generated after the carton is slotted and die-cut will slide out through the discharge port 17. The waste can be collected uniformly by placing the collecting device under the discharge port 17. After the slotting is completed, the first push plate 20 can be driven to move toward the top of the lower die-cutting groove 2 by the extension of the output end of the second electric telescopic rod 18, so that the carton with the slotted top of the lower die-cutting groove 2 can be pushed down to the top of the lower die-cutting groove 2. Repeat the above operation to perform the die-cutting and slotting operation on the carton.
