Description

Technical Field

[0001] This utility model relates to the field of punching device technology, specifically a pneumatic punching device for the production of packaging paper bags. Background Technology

[0002] Packaging paper is a general term for a type of paper used for packaging purposes. It can be divided into ordinary packaging paper, special packaging paper, label paper, greaseproof packaging paper, and moisture-proof packaging paper, etc. It typically possesses high strength and toughness. Different types of packaging paper have different properties and uses. For example, special fruit packaging paper is thin and soft. Photosensitive protective paper is opaque. Greaseproof packaging paper (such as vegetable parchment) has anti-grease penetration properties. Moisture-proof packaging paper (such as asphalt paper, oil paper, and aluminum foil paper) is moisture-proof. Label paper is used for packaging after printing. Ordinary packaging paper is mostly used for general commodity packaging, and its quality requirements are not strict.

[0003] A current pneumatic punching device for producing packaging paper bags, as described in patent CN217514669U, comprises: a base plate, with a gasket fixedly connected to the bottom surface of the base plate; a support rod fixedly connected to the upper surface of the base plate; a top plate fixedly connected to the end of the support rod away from the base plate; and a control mechanism positioned above the base plate. Through the cooperation of the control mechanism, the punching mechanism, and the fixing mechanism, the fixing mechanism first secures the packaging paper according to actual needs. Then, under the action of the control mechanism, the punching mechanism can be adjusted according to actual needs, allowing it to be controlled in a suitable position and perform circular array punching. This eliminates the need for pre-marking when punching the packaging paper, thus solving the problem of increased labor intensity caused by the current practice of pre-marking during drilling.

[0004] Regarding the aforementioned related technologies, the applicant discovered that a pneumatic punching device for packaging paper bag production punches holes in the paper bag using a drill rod. After punching, fragments of the punched paper bag are left on the bottom plate. After prolonged punching, a large amount of paper bag fragments accumulate on the surface of the bottom plate. When the punched paper bag is removed, the fragments on the bottom plate are dragged along with the bag, causing paper bag fragments to be scattered around the work environment, making subsequent collection inconvenient. Therefore, we propose a pneumatic punching device for packaging paper bag production. Utility Model Content

[0032] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0033] Please see Figures 1-3 The diagram illustrates a pneumatic punching device for producing paper bags, comprising a workbench 1 and a collection trough 101. A fixed frame 102 is fixedly mounted on the top of the workbench 1. A cylinder 103 is mounted on the top wall of the fixed frame 102. A sliding plate 104 is mounted on the telescopic end of the cylinder 103. The sliding plate 104 is slidably connected to the bottom of the fixed frame 102. Hydraulic rods 105 are mounted at both ends of the bottom of the sliding plate 104. A fixed plate 106 is fixed to the telescopic end of the hydraulic rods 105. A punching assembly 2 is mounted on the bottom of the sliding plate 104. The punching assembly 2 includes a stepper motor 201. The stepper motor 201 and the sliding plate 104 are connected... 4 are fixedly connected. One end of the output shaft of the stepper motor 201 is fixedly provided with a fixed seat 202. The fixed seat 202 is rotatably connected with a threaded rod 203. One end of the threaded rod 203 is fixedly provided with a throttle 2031. The outer wall of the threaded rod 203 is threadedly connected with a threaded sleeve 204. The bottom of the threaded sleeve 204 contacts the top wall of the fixed seat 202, thereby limiting the movement of the threaded sleeve 204. The bottom of the threaded sleeve 204 is fixedly provided with a pneumatic push rod 205. One end of the pneumatic push rod 205 is fixedly provided with a first motor 206. One end of the output shaft of the first motor 206 is fixedly provided with a drill rod 2061.

[0034] When punching holes in the packaging paper bag, the paper bag is laid on the top of the workbench 1. Then, the control cylinder 103 pushes the slide plate 104 to move downward under the limit of the fixed frame 102, and the hydraulic rod 105 controls the fixed plate 106 to fix the two ends of the packaging paper bag. Then, the throttle 2031 is turned to drive the threaded rod 203 to rotate synchronously. Through the rotation of the threaded rod 203, the threaded sleeve 204, the pneumatic push rod 205, the first motor 206 and the drill rod 2061 are driven to move horizontally until the drill rod 2061 is moved to the appropriate position. Then, the first motor 206 controls the drill rod 2061 to punch holes in the packaging paper bag. By controlling the stepper motor 201 to rotate the fixed seat 202 precisely, the circular array of holes in the packaging paper bag can be achieved.

[0035] Please see Figures 1-5In the figure, a collection component 3 is installed at the bottom of the workbench 1 near the collection tank 101. The collection component 3 includes a collection box 301, which is fixedly connected to the workbench 1. The collection box 301 and the collection tank 101 are connected through an air duct 302. A sleeve 303 is fixedly provided on the outer wall of the collection box 301. The collection box 301 and the sleeve 303 are connected. A second motor 304 is installed on the outer wall of the sleeve 303. A fan blade 305 is provided inside the sleeve 303. One end of the fan blade 305 is connected to the output shaft of the second motor 304. A filter plate 306 is installed between the collection box 301 and the sleeve 303. A collection box 307 is squeezed and connected to the bottom of the inside of the collection box 301.

[0036] After the punching operation of the packaging paper bag is completed, the control cylinder 103 moves the punching component 2 upward, and then removes the paper bag. Next, the second motor 304 in the collection component 3 is started. The output shaft of the second motor 304 drives the fan blade 305 to rotate, causing the fan blade 305 to blow air towards one end of the second motor 304. This creates a negative pressure inside the collection box 301 and the air duct 302, causing the paper bag fragments that fall into the collection trough 101 to be sucked into the collection box 301 through the air duct 302. Due to their own gravity, they fall into the collection box 307, where they are collected. Driven by the second motor 304 in the collection component 3, the automatic collection of paper bag fragments after punching is achieved, thus avoiding the phenomenon of paper bag fragments scattering all over the ground after the punching operation. This not only improves the quality of the surrounding working environment but also achieves unified collection and processing of paper bag fragments, improving the practicality of the device during use.

[0037] Please see Figures 1-5 The diagram shows that a feeding assembly 4 is installed on one side of the outer wall of the slide plate 104. The feeding assembly 4 includes a transmission rack 401, which is fixedly connected to the slide plate 104. A rotating shaft 402 is rotatably connected to the middle position of one side of the outer wall of the workbench 1. A gear 4021 is fixedly provided on the outer wall of the rotating shaft 402. The transmission rack 401 and the gear 4021 are on the same horizontal plane. The bottom of the transmission rack 401 is lower than the bottom of the drill rod 2061. The transmission rack 401 and the gear 4021 are connected by transmission. A toothed plate 403 is provided on the outer wall of the gear 4021. The toothed plate 403 meshes with the gear 4021. A transmission rod 404 is fixedly provided at the bottom of one side of the outer wall of the toothed plate 403. A support plate 405 is fixedly provided at one end of the transmission rod 404. The transmission rod 404 passes through the interior of the collection trough 101 and is slidably connected to the collection trough 101. A collection trough 4051 for the support plate 405 to be stored is opened at the bottom of the collection trough 101.

[0038] As the slide plate 104 moves downward, the transmission rack 401 moves downward simultaneously and then meshes with the gear 4021. The continued downward movement of the slide plate 104 drives the transmission rack 401 to rotate the gear 4021. The rotation of the gear 4021 sequentially drives the toothed plate 403, transmission rod 404, and support plate 405 to move upward in sequence. When the slide plate 104 completes its downward movement, the support plate 405 simultaneously moves upward, ensuring that the top of the support plate 405 is level with the top of the workbench 1. After the paper bag is punched, the paper bag fragments are automatically... The paper bag fragments fall onto the surface of the tray 405 and move downwards along with the slide plate 104 until the tray 405 is completely moved into the collection slot 4051. At this point, under the influence of the collecting component 3, the paper bag is sucked away from the top of the tray 405. Then, through the cooperation of the slide plate 104 and the transmission rack 401 in the feeding component 4, the automatic movement of the tray 405 is realized. Without consuming additional energy, continuous automatic feeding of packaging paper bag fragments is achieved, saving energy and improving the automation level of the device.
