Description

Technical Field

[0001] This utility model relates to the field of cardboard box manufacturing technology, specifically to a folding machine for cardboard box production and processing. Background Technology

[0002] A carton folding machine is a type of mechanical equipment used in the production of cartons. It is mainly used to fold cartons according to a predetermined folding method to form finished cartons, which facilitate subsequent storage and transportation.

[0003] To ensure that the suction cup mechanism can stably pick up the cardboard, existing cardboard folding machines have a fixed baffle placed above and to the side of the cardboard. As the suction cup mechanism moves the cardboard, the baffle exerts a large force on the outer wall of the cardboard because it is fixed. This may damage the outer wall of the cardboard and affect the overall quality of the cardboard. Therefore, we propose a folding machine for cardboard production and processing. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a folding machine for carton production and processing to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a folding machine for carton production and processing, comprising a machine housing, a suction cup mechanism and a cardboard frame for holding the carton, wherein a support rod is provided inside the machine housing, and a plurality of blocking components are provided on the support rod to block the movement of the carton, the blocking components blocking the carton on the cardboard frame;

[0006] The blocking component includes an elastic telescopic rod, the bottom of which is provided with a blocking block for blocking the cardboard box on the side closest to the suction cup mechanism.

[0007] Furthermore, the blocking block is inclined toward one side of the cardboard shell, and its inclined surface abuts against the top of the cardboard shell.

[0008] Furthermore, the elastic telescopic rod includes a thick rod with a hollow bottom and a thin rod. The top of the thin rod is slidably connected to the hollow cavity of the thick rod and connected by a first spring. The bottom of the thin rod is connected to a blocking block. The side wall of the thin rod is provided with a cavity, in which a limiting block is slidably connected and connected by a second spring. The top of the limiting block abuts against the bottom of the thick rod, and its bottom has a sloping structure. The bottom of the thick rod is provided with a protrusion above the limiting block.

[0009] The suction cup mechanism is equipped with a squeezing rod that works in conjunction with the limiting block to push the bottom slope of the limiting block. The protrusion has a cavity inside to accommodate the upward-moving limiting block.

[0010] Furthermore, the top of the thick rod is provided with a U-shaped mounting block installed on the outer wall of the support rod, and the U-shaped mounting block is provided with a hand-tightening screw that passes through the support rod.

[0011] Furthermore, the upper side of the U-shaped mounting block is provided with a through hole and the lower side is provided with a corresponding threaded groove. The hand-tightening screw passes through the through hole and the support rod and is screwed into the threaded groove.

[0012] Furthermore, the cardboard frame is provided with a paper pressing component, which includes a lower pressing plate that moves along the cardboard frame and a vertical pressing plate that abuts against the side wall of the cardboard. The top of the vertical pressing plate is inclined away from the side of the cardboard.

[0013] This utility model provides a folding machine for cardboard box production and processing. It has the following beneficial effects:

[0014] 1. When the suction cup mechanism picks up the cardboard box from the cardboard frame, the thin rod will move upward, so that the limiting block no longer abuts against the cardboard box. When the suction cup mechanism drives the cardboard box to move, the thin rod will be resisted when it returns to its original position. Its return speed is less than the speed at which the suction cup mechanism drives the cardboard box to move. This avoids the blocking block from creating resistance to the movement of the cardboard box and prevents surface damage to the cardboard box during the movement process, which would affect the overall quality of the carton.

[0015] 2. By setting a limit block, the blocking block can be prevented from moving upward under the pressure of the cardboard, causing the cardboard to fall directly and affecting subsequent work. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See attached document Figure 1-5 A folding machine for carton production and processing includes a machine housing 1, a suction cup mechanism 2, and a cardboard frame 3 for holding the carton. The machine housing 1 is provided with a support rod 4, and the support rod 4 is provided with a plurality of blocking components that block the movement of the carton. The blocking components block the carton on the cardboard frame 3. The suction cup mechanism 2 moves to the cardboard frame 3 and suctions and pulls the carton on it. The movement of the carton is blocked by the blocking components.

[0024] The blocking component includes an elastic telescopic rod. The bottom of the elastic telescopic rod is provided with a blocking block 53 for blocking the cardboard box 3 on the side closest to the suction cup mechanism 2. When the suction cup mechanism 2 picks up the cardboard box, the elastic telescopic rod retracts, so that the blocking block 53 does not block the cardboard box. When the cardboard box moves beyond the blocking block 53, the blocking block 53 returns to its initial state, so as to avoid the cardboard box being damaged by the resistance of the blocking block 53, which would affect the overall quality of the carton.

[0025] The blocking block 53 is inclined toward one side of the cardboard shell, and its inclined surface abuts against the top of the cardboard shell, so that the blocking block 53 can block the cardboard shell on the cardboard frame 3.

[0026] In this embodiment, the elastic telescopic rod includes a thick rod 51 with a hollow bottom and a thin rod 52. The top of the thin rod 52 is slidably connected to the hollow cavity of the thick rod 51 and is connected by a first spring 54. The bottom of the thin rod 52 is connected to the blocking block 53. The side wall of the thin rod 52 is provided with a cavity, in which a limiting block 55 is slidably connected and connected by a second spring 56. The top of the limiting block 55 abuts against the bottom of the thick rod 51. By setting the limiting block 55, the blocking block 53 can be prevented from moving upward under the pressure of the cardboard, causing the cardboard to fall directly.

[0027] The suction cup mechanism 2 is equipped with a pressing rod 21 that works in conjunction with the limiting block 55. This rod pushes the inclined surface at the bottom of the limiting block 55. The bottom of the thick rod 51, positioned above the limiting block 55, has a protrusion 57 with a cavity inside. This cavity is designed to hold the upward-moving limiting block 55. During the suction cup mechanism 2's process of picking up the cardboard, the pressing rod 21 first presses the inclined surface at the bottom of the limiting block 55, causing the limiting block 55 to move into the cavity of the thin rod 52, and then upward into the cavity of the protrusion 57. At this time, the thin rod 52 drives the blocking block 53 to move upward. When the blocking block 53 is no longer against the paper shell, the suction cup mechanism 2 just holds the paper shell. When the suction cup mechanism 2 drives the paper shell to move, under the action of the second spring 56, the limiting block 55 abuts against the inner cavity of the protrusion 57, so that the thin rod 52 and the thick rod 51 have friction in the hollow cavity. The reset speed of the thin rod 52 under the push of the first spring 54 is less than the speed at which the suction cup structure 2 drives the paper shell to move. When the paper shell moves beyond the bottom of the limiting block 55, the limiting block 55 will reset to the initial state to avoid the limiting block 55 affecting the movement of the paper shell and causing damage to the paper shell.

[0028] In this embodiment, the top of the thick rod 51 is provided with a U-shaped mounting block 6 installed on the outer wall of the support rod 4. The U-shaped mounting block 6 is provided with a hand-tightening screw 7 that passes through the support rod 4. The blocking component is installed, fixed and its position is adjusted by the cooperation of the hand-tightening screw 7 and the U-shaped mounting block 6, so that the blocking component can limit the cardboard of different models.

[0029] In this embodiment, the upper side of the U-shaped mounting block 6 is provided with a through hole 61 and the lower side is provided with a corresponding threaded groove 62. The hand-tightening screw 7 passes through the through hole 61 and the support rod 4 and is screwed into the threaded groove 62 to increase the fixing force of the hand-tightening screw 7 on the U-shaped mounting block 6 and the support rod 4.

[0030] In this embodiment, the cardboard frame 3 is provided with a paper pressing component to prevent the cardboard from being pushed and tilted by the suction cup mechanism 2, which would affect subsequent work and facilitate the movement of the cardboard on the cardboard frame 3. The paper pressing component includes a lower pressing plate 31 that moves along the cardboard frame 3 and a vertical pressing plate 32 that abuts against the side wall of the cardboard. The top of the vertical pressing plate 32 is inclined away from the cardboard, which makes it easier to place the cardboard on the side of the paper pressing component that is close to the blocking component.

[0031] Working principle: Place the cardboard box on the cardboard frame 3. At this time, the cardboard box is located between the vertical pressure plate 32 and the blocking block 53.

[0032] When the device is working, the suction cup mechanism 2 picks up the cardboard box on the cardboard frame 3. During this process, the squeezing rod 21 squeezes the bottom slope of the limiting block 55, so that the limiting block 55 first moves into the thin rod 52, and then pushes the thin rod 52 upward, so that the limiting block 55 no longer abuts against the cardboard box. When the suction cup mechanism 2 drives the cardboard box to move, the thin rod 52 is resisted when it returns to its downward position. Its return speed is less than the speed at which the suction cup mechanism 2 drives the cardboard box to move, thus avoiding the blocking block 53 from generating resistance to the movement of the cardboard box and preventing surface damage to the cardboard box during the movement process, which would affect the overall quality of the carton.
