Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing, specifically a packaging cardboard box punching device that facilitates adjustment of the punching diameter. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. The production process of cardboard boxes involves punching cardboard into the required shape, then punching and punching holes according to needs, and finally folding and gluing them together to form the desired cardboard box.

[0003] Current cardboard box punching devices mainly consist of a punching guide tube and a drive mechanism. When working, the drive mechanism moves the punching guide tube downwards, thereby punching holes of the corresponding size into the cardboard. When holes of other diameters need to be punched, the previous punching guide tube needs to be disassembled and replaced with a punching guide tube of the corresponding diameter, which makes it inconvenient to adjust the punching diameter. Utility Model Content

[0004] The purpose of this invention is to provide a packaging carton punching device that facilitates adjustment of the punching diameter, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A perforation device for packaging cartons with easily adjustable perforation diameter, comprising:

[0007] A support mechanism includes a base, a U-shaped frame fixedly connected to the top of the base, hydraulic rods symmetrically fixed through the interior of the U-shaped frame, a movable plate fixedly connected to the output ends of the two sets of hydraulic rods, a stepper motor fixedly connected to the top of the movable plate, a rotating shaft fixedly connected to the output end of the stepper motor, and a turntable fixedly connected to the bottom of the rotating shaft.

[0008] The switching mechanism includes punching blade tubes arranged in a circular array that slide through the interior of the turntable. Each group of punching blade tubes has a different inner diameter. A fixing plate is fixedly connected to the top of each group of punching blade tubes. A first spring is fixedly connected between each group of fixing plates and the turntable. A guide post is fixedly connected to one side of the top of each group of fixing plates. A guide ring corresponding to each group of guide posts is fixedly connected to the bottom of the moving plate. A protrusion is fixedly connected to one side of the bottom of the guide ring.

[0009] As a further embodiment of this utility model: guide rods are fixedly connected to the top four corners of the movable plate, and each set of guide rods slides through the U-shaped frame.

[0010] As a further embodiment of this utility model: the top of the turntable is fixedly connected with multiple reinforcing ribs in a circular array, and each group of reinforcing ribs is fixedly connected to the rotating shaft.

[0011] As a further embodiment of this utility model: each group of punching tubes is fitted with a push rod inside, each group of push rods is slidably connected to each group of fixed plates, and each group of push rods is fixedly connected to a top block, with a second spring fixedly connected between the top block and the fixed plate.

[0012] As a further embodiment of this utility model: each group of push rods has a push block fixedly connected to the end away from the top block, and the diameter of each group of push blocks is smaller than the inner diameter of each group of punching tubes.

[0013] As a further embodiment of this utility model: each group of punching tubes has a beveled opening at the bottom, and each group of guide posts has a ball bearing movably connected to the top.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] With the above-described structure, this invention utilizes the cooperation of a stepper motor, turntable, punching tubes, and protrusions. When holes of different diameters need to be punched, the stepper motor can be activated, driving the rotating shaft and turntable to rotate. The turntable's rotation causes each set of punching tubes, the fixing plate, and the guide post to rotate as well. As the guide post rotates, it moves along the bottom of the guide ring or the protrusion. When a punching tube of a corresponding diameter rotates to align with the protrusion, the corresponding guide post moves to the bottom of the protrusion. At this point, the corresponding ball bearing and the corresponding guide post move downwards. This downward movement of the guide post causes the corresponding fixing plate and the corresponding punching tube to move downwards as well, making the corresponding punching tube lower than the height of the other sets of punching tubes. This allows for switching between punching tubes of different diameters, facilitating the adjustment of the punching diameter of the cardboard box. Attached Figure Description

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Please see Figure 1-4 A packaging carton punching device with adjustable punching diameter includes a support mechanism 1. The support mechanism 1 includes a base 101, which provides support for the cardboard to be punched. A U-shaped frame 102 is fixedly connected to the top of the base 101. Hydraulic rods 103 are symmetrically fixed through the interior of the U-shaped frame 102. The output ends of the two sets of hydraulic rods 103 are fixedly connected to a movable plate 105. The hydraulic rods 103 are used to drive the movable plate 105 to move up and down when the device is started. Guide rods 104 are fixedly connected to the four corners of the top of the movable plate 105. Each set of guide rods 104 slides through the U-shaped frame 102 and guides the up and down movement of the movable plate 105.

[0024] A stepper motor 109 is fixedly connected to the top of the movable plate 105. A rotating shaft 106 is fixedly connected to the output end of the stepper motor 109. A turntable 108 is fixedly connected to the bottom of the rotating shaft 106. The stepper motor 109 is configured to drive the rotating shaft 106 and the turntable 108 to rotate when the machine starts working. Multiple reinforcing ribs 107 are fixedly connected in a circular array on the top of the turntable 108. Each set of reinforcing ribs 107 is fixedly connected to the rotating shaft 106. The reinforcing ribs 107 are configured to further connect and fix the turntable 108 and the rotating shaft 106, thereby improving the connection stability between the turntable 108 and the rotating shaft 106. A switching mechanism 2 includes a punching blade tube 201 that slides through the turntable 108 in a circular array. The punching blade tube 201 is configured to punch the cardboard on the base 101 when moving downwards, thereby punching holes of the corresponding diameter into the cardboard.

[0025] Each set of punching tubes 201 has a bevel 203 at its bottom, which facilitates cutting and punching the cardboard as the punching tube 201 moves downward. Each set of punching tubes 201 has a different inner diameter, allowing for the punching of holes of varying diameters. Each set of punching tubes 201 has a fixed plate 202 at its top, and each set of punching tubes 201 has a push rod 209 fitted inside. Each push rod 209 is slidably connected to its respective fixed plate 202. The fixed plate 202 is used to push out any pieces of paper stuck inside the punching tube 201 during punching when it moves downward.

[0026] Each push rod 209 has a top block 210 fixedly connected to its top. A second spring 211 is fixedly connected between the top block 210 and the fixing plate 202. The top block 210 and the second spring 211 provide support for the push rod 209. Each push rod 209 has a push block 212 fixedly connected to the end away from the top block 210. The diameter of each push block 212 is smaller than the inner diameter of each punching tube 201. The push block 212 is designed to move up and down synchronously with the push rod 209, so that when the push block 212 moves downward with the push rod 209, it can push the paper inside the punching tube 201 out of the punching tube 201.

[0027] Each set of fixed plates 202 is fixedly connected to the turntable 108 with a first spring 204. Specifically, the first spring 204 is in a compressed state, allowing it to pull the fixed plate 202 and the punching tube 201 up and down. A guide post 205 is fixedly connected to one side of the top of each set of fixed plates 202. The guide post 205 is used to push the ball bearings 206 and the punching tube 201 up and down. A guide ring 207 corresponding to each set of guide posts 205 is fixedly connected to the bottom of the moving plate 105. A protrusion 208 is fixedly connected to one side of the bottom of the guide ring 207. The guide ring 207 and the protrusion 208 guide the guide post 205. A ball bearing 206 is movably connected to the top of each set of guide posts 205. The ball bearing 206 reduces friction between the guide post 205 and the guide ring 207, allowing the ball bearing 206 to roll along the bottom of the guide ring 207 and the protrusion 208.

[0028] In use, the cardboard box to be punched is placed on the base 101. Then, the stepper motor 109 is started, which drives the rotating shaft 106 and the turntable 108 to rotate. When the turntable 108 rotates, it drives the various sets of punching tubes 201, the fixing plate 202, and the guide post 205 to rotate as well. When the guide post 205 rotates, the ball bearings 206 can roll along the bottom of the guide ring 207 or the protrusion 208. When the punching tube 201 of the corresponding diameter rotates to correspond with the protrusion 208, the corresponding ball bearing 206 rolls to the bottom of the protrusion 208. At this time, the corresponding ball bearing 206 and the corresponding guide post 205 move downwards. When the guide column 205 moves downward, it can drive the corresponding fixed plate 202 and the corresponding punching tube 201 to move downward as well, so that the height of the corresponding punching tube 201 is lower than that of the other groups of punching tubes 201. This moves the position of the cardboard to be punched to be directly below the corresponding punching tube 201. Then, the hydraulic rod 103 is activated, so that when the hydraulic rod 103 starts working, it can drive the moving plate 105, the rotating shaft 106, the turntable 108 and the groups of punching tubes 201 to move downward. Since the height of the corresponding punching tube 201 is lower than that of the other groups of punching tubes 201, the corresponding punching tube 201 contacts the cardboard first, thereby realizing the punching and punching of the cardboard.

[0029] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
