Description

Technical Field

[0001] This utility model belongs to the field of packaging box punching technology, and relates to a packaging box punching device. Background Technology

[0002] Packaging refers to boxes used to encase products, primarily for ensuring product safety during transportation and enhancing the product's perceived quality. Most packaging boxes are made of paper for environmental reasons. To allow for the flow of air between the inside and outside of the packaging box, holes are usually punched in it.

[0003] Existing Chinese patent CN222681107U discloses a punching device for packaging boxes, including a base, a drive motor fixedly mounted on the base, and a drive disk fixedly mounted on the drive motor drive shaft; the drive disk has a placement slot for placing the packaging box, and the placement slot has an opening inside; a mounting bracket is fixedly mounted on one side of the base, a cylinder is fixedly mounted on the mounting bracket, and a punch is fixedly mounted on the cylinder drive rod; it also includes an air supply mechanism that supplies air when the punch moves downward to remove waste material inside the punch. This utility model proposes a punching device for packaging boxes. By providing an air supply mechanism, this utility model allows waste material inside the punch to be discharged when the punch moves downward, facilitating subsequent use.

[0004] However, in use, the aforementioned device lacks a corresponding limiting mechanism during the rotation of the packaging box to directly below the punch, due to the placement groove on the edge of the drive disc. This causes the packaging box to shift position within the groove due to inertia and centrifugal force as the drive disc rotates, affecting the consistency of punching. Furthermore, when the punch is lifted, it can easily lift the packaging box, potentially damaging it during the drive disc's rotation. Additionally, if the punch's vertical stroke is too short, unstable air pressure can easily occur, leading to problems such as the box not being able to be punched or excessive airflow blowing the box away. Therefore, this invention provides a packaging box punching device to solve these problems. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model discloses a packaging box punching device. The technical solution adopted includes a frame, the frame including a base and support legs arranged in a circular array on the lower edge of the base. A circular groove is formed in the middle of the upper surface of the base. A station switching mechanism is rotatably installed in the circular groove. The station switching mechanism includes a rotating disk. The center of the lower surface of the rotating disk is fixedly connected to the output shaft of a servo motor installed under the base. Several placement grooves are formed on the circumferential edge of the upper surface of the rotating disk. A through hole is opened at the bottom of the placement trough. A positioning punching mechanism is fixedly installed on the rear edge of the upper surface of the base. The positioning punching mechanism includes a Z-shaped bracket. A cylinder is installed through an opening in the upper horizontal arm of the Z-shaped bracket, which faces the through hole. A trough is opened at the lower part of the telescopic shaft of the cylinder. A punch is inserted into the trough. The rear side wall of the punch is connected to a solenoid valve installed at the upper end of the vertical arm of the bracket through a hose. An electric telescopic rod is installed on the lower rear side of the vertical arm of the Z-shaped bracket. A positioning plate is fixedly installed at one end of the telescopic shaft of the electric telescopic rod that passes through the bracket.

[0006] As a preferred embodiment of this utility model, the edge of the circular recess and the lower surface edge of the rotating disk are respectively provided with sliding grooves, and ball bearings are provided in the sliding grooves; by using ball bearings, the friction between the base and the rotating disk can be reduced, thereby reducing the movement resistance of the rotating disk.

[0007] As a preferred embodiment of this utility model, the bottom of the placement groove is flush with the upper surface of the base; this design facilitates the sliding of the packaging box that needs to be punched into or out of the placement groove on the rotating disk, and at the same time, it also facilitates the electric telescopic rod to drive the positioning plate to freely extend and retract into the placement groove to fix and limit the packaging box.

[0008] In a preferred embodiment of this utility model, a chip removal hole is formed through the circular groove corresponding to the through hole.

[0009] As a preferred embodiment of this utility model, the punch is inserted into the right side of the cylinder telescopic shaft and fixed by a stop screw screwed on the right side of the cylinder telescopic shaft; the use of a stop screw for fixing facilitates the disassembly and replacement of the punch.

[0010] As a preferred embodiment of this utility model, a touch screen is installed on the front edge of the lower surface of the base, and a controller is installed on the right edge of the lower surface of the base.

[0011] The beneficial effects of this utility model are:

[0012] By designing an electric telescopic rod in the positioning punching mechanism to drive the positioning plate, the packaging box placed in the sink can be precisely positioned, avoiding displacement during punching, improving the consistency of punching, and solving the problem of the punch lifting the packaging box.

[0013] After the punch penetrates the packaging box and extends into the through hole, high-pressure gas is introduced into the punch through a hose by controlling the switch of the solenoid valve on the back of the punch. This quickly blows out the paper scraps stuck inside the punch, improving the stability of the scrap removal and effectively avoiding the problem of paper scraps getting stuck in the punch due to unstable air pressure in existing patents.

Detailed Implementation

[0019] Example 1

[0020] like Figs. 1 to 4As shown, the packaging box punching device of this utility model adopts the following technical solution: It includes a frame 1, which includes a base 11 and support legs 12 arranged in a circular array on the lower edge of the base. A circular recess 13 is formed in the middle of the upper surface of the base 11. A chip removal hole 14 is formed through the circular recess 13 corresponding to the through hole 24. A station switching mechanism 2 is rotatably installed in the circular recess 13. The station switching mechanism 2 includes a rotating disk 21. The center of the lower surface of the rotating disk 21 is fixedly connected to the output shaft of a servo motor 22 installed under the base. Several placement recesses 23 are formed circumferentially on the upper surface of the rotating disk 21. The bottom of the placement recesses 23 is flush with the upper surface of the base 11. Through holes 24 are formed at the bottom of the placement recesses 23. The edges of the circular recesses 13 are separated from the edges of the lower surface of the rotating disk 21. A corresponding sliding groove is provided, and a ball bearing 25 is provided in the sliding groove. A positioning punching mechanism 3 is fixedly installed on the rear edge of the upper surface of the base 11. The positioning punching mechanism 3 includes a Z-shaped bracket 31. A cylinder 32 is installed through an opening in the upper horizontal arm of the Z-shaped bracket 31, which is directly opposite the through hole 24. A recess is provided in the lower part of the telescopic shaft of the cylinder 32. A punch 33 is inserted in the recess. The rear side wall of the punch 33 is connected to a solenoid valve 35 installed on the upper end of the vertical arm of the bracket through a hose 34. An electric telescopic rod 36 is installed on the lower rear side of the vertical arm of the Z-shaped bracket 31. A positioning plate 37 is fixedly installed at one end of the telescopic shaft of the electric telescopic rod 36 that passes through the bracket. The width of the positioning plate 37 is smaller than the width of the recess 23. The punch 33 is inserted into the right side of the telescopic shaft of the cylinder 32 and fixed by a stop screw 38 screwed on the right side of the telescopic shaft of the cylinder 32.

[0021] A touch screen 4 is installed on the front edge of the lower surface of the base 11, and a controller 5 is installed on the right edge of the lower surface of the base 11. The controller 5 is electrically connected to the servo motor 22, the cylinder 32, the solenoid valve 35, the electric telescopic rod 36, and the touch screen 4. The controller 5 receives operation commands input from the touch screen 4, controls the start and stop of the servo motor 22 and its rotation angle to drive the rotating disk 21 to precisely switch work positions, controls the extension and retraction of the electric telescopic rod 36 to drive the positioning plate 37 to position and fix the packaging box, controls the extension and retraction of the cylinder 32 to drive the punch 33 to complete the punching action, and controls the opening and closing of the solenoid valve 35 to supply air to the punch 33 through the hose 34, so as to realize the coordinated work of each component.

[0022] The working principle of this utility model is as follows: The packaging box to be punched is placed in the placement groove 23 of the rotating disk 21. After receiving the operation command through the touch screen 4, the controller 5 controls the servo motor 22 to start, driving the rotating disk 21 to rotate in the circular groove 13. The ball bearing 25 reduces rotational friction, so that the placement groove 23 is accurately moved below the positioning punching mechanism 3. At this time, the electric telescopic rod 36 extends, pushing the positioning plate 37 into the placement groove 23 to position and fix the packaging box. Then, the cylinder 32 extends, driving the punch 33 to move down to punch the packaging box. The waste generated during punching can easily get stuck inside the punch 33. After the punch 33 passes through the packaging box, the control solenoid valve 35 introduces high-pressure gas into the punch 33 through the hose 34. The high-pressure gas blows the stuck debris out through the through hole 24 at the bottom of the placement trough 23 and the corresponding chip discharge hole 14 at the bottom. Then the solenoid valve 35 is closed, the cylinder 32 drives the punch 33 back to its original position, the electric telescopic rod 36 retracts and resets, and the servo motor 22 drives the rotating disk 21 to rotate again, moving the next placement trough 23 to the processing position, and the continuous punching operation is completed in a cycle.
