Description

Technical Field

[0001] The utility model belongs to the technical field of punching bags, and specifically relates to a punching device with an anti-displacement function for forming a handle hole of a packaging bag. Background Art

[0002] A packaging bag refers to a bag used for packaging various articles, which facilitates the transportation of goods during the production and circulation process and is easy to store. It is widely used in daily life and industrial production. Most commonly used packaging bags are made of paper. During the production process of packaging bags, according to the design and usage requirements of the packaging bags themselves, it is necessary to punch holes in the packaging bags, such as handle holes, hanging holes, etc. Therefore, a punching device is required during the production process of packaging bags.

[0003] In Chinese Patent CN221024666U, a packaging bag punching device is disclosed, belonging to the technical field of punching devices. A packaging bag punching device includes a workbench and a centering mechanism arranged on the top of the workbench for limiting the packaging bag. A groove block is arranged on the outer wall of the top of the workbench, a punching cylinder is installed on the outer wall of the top of the groove block, an installation block is arranged on the outer wall of the bottom of the groove block, a punching head is arranged at the bottom of the installation block, and one end of the piston rod of the punching cylinder is fixedly connected to the outer wall of the top of the installation block. A collection groove is formed on the other side of the outer wall of the top of the workbench.

[0004] Most of the existing packaging bag punching devices do not have the function of centering the packaging bag. If the packaging bag is not centered, the phenomenon of multiple packaging bags being placed unevenly will occur. As a result, when punching holes, the punching positions of multiple packaging bags will be different. In actual use, it is often the case that workers stack multiple packaging bags in the punching device for punching, which is rather troublesome. In the above document, by rotating the first rotating rod until the two clamping plates are attached to both ends of the packaging bag, multiple packaging bags can be centered. However, since the packaging bag is generally relatively soft, when the clamping plate clamps the packaging bag, due to the lack of a limiting component, when the first rotating rod rotates excessively, the clamping plate will squeeze the packaging bag to make it arch, thereby affecting the normal punching operation. Therefore, when rotating the first rotating rod, workers need to highly concentrate their attention, and it is rather troublesome to use.

[0005] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0006] Regarding the problems in the related art, the utility model provides a punching device with an anti-displacement function for forming a handle hole of a packaging bag to overcome the above-mentioned technical problems existing in the prior related art.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to a punching device with an anti-displacement function for forming a handle hole of a packaging bag, which comprises a workbench. A limiting component and a first positioning component are arranged inside the workbench. A punching component is fixedly connected to the top of the workbench. A second positioning component is fixedly connected to the outer surface of the punching component. The limiting component is used for limiting and fixing the first positioning component. The first positioning component is used for fixing the packaging bag from both sides. The second positioning component is used for fixing the packaging bag from above.

[0009] Further, the limiting component comprises a first screw rod. A sliding groove is formed on the outer surface of the workbench. The first screw rod is rotatably connected inside the sliding groove. A first hand wheel is fixedly connected to the end of the first screw rod. A limiting block is threadedly connected to the outer surface of the first screw rod. The limiting block is slidably connected inside the sliding groove. A round hole is formed on the outer surface of the limiting block.

[0010] Further, the first positioning component comprises a second screw rod. The second screw rod is rotatably connected inside the sliding groove. A second hand wheel is fixedly connected to the end of the second screw rod. A sliding baffle is threadedly connected to the outer surface of the second screw rod. The sliding baffle is slidably connected to the sliding groove. The second screw rod passes through the round hole.

[0011] Further, the punching component comprises a bracket. An electric push rod is fixedly connected to the outer surface of the bracket. A punching head is fixedly installed at the movable end of the electric push rod.

[0012] Further, the second positioning component comprises a connecting rod. The connecting rod is fixedly connected to the movable end of the electric push rod. A spring is fixedly connected inside the connecting rod. A sliding rod is slidably connected inside the connecting rod. A pressing plate is fixedly connected to the lower end of the sliding rod.

[0013] Further, a collecting component is arranged on the workbench.

[0015] The utility model has the following beneficial effects:

[0016] 1. Through the connection between the limiting component and the first positioning component, the limiting component is adjusted to be equal to the width of the packaging bag. The first positioning component moves along the limiting component, and the limiting component restricts the moving distance of the first positioning component. When the first positioning component contacts the limiting component, a slight collision occurs and a sound is emitted, which can remind the staff that the first positioning component has moved in place at this time, avoiding the situation that the first positioning component moves excessively and squeezes the packaging bag. The staff only needs to listen to the sound prompt, which is relatively easy and convenient to use.

[0017] 2. Through the connection between the limiting block and the sliding baffle, first adjust the distance between the two limiting blocks so that the distance between the outer sides of the two limiting blocks is the same as the width of the packaging bag. Then push the sliding baffle to rotate. The sliding baffle pushes the packaging bag on the workbench to move and center it. When the sliding baffle contacts the limiting block, a slight collision occurs and a sound is emitted, prompting the staff to stop pushing the sliding baffle. Even if the sliding baffle is continuously pushed, it is blocked by the limiting block and cannot move, thus avoiding the situation that the sliding baffle moves excessively and squeezes the packaging bag, making it more convenient to use.

[0018] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the utility model.

[0030] Please refer to Figures 1-6 As shown, the present utility model is a punching device with an anti-misalignment function for forming the handle holes of packaging bags, including a workbench 1. A limiting component 2 and a first positioning component 3 are arranged inside the workbench 1. A punching component 4 is fixedly connected to the top of the workbench 1. A second positioning component 5 is fixedly connected to the outer surface of the punching component 4. The limiting component 2 is used to limit and fix the first positioning component 3. The first positioning component 3 is used to fix the packaging bag from both sides. The second positioning component 5 is used to fix the packaging bag from above.

[0031] First, adjust the position of the limiting component 2 according to the width of the packaging bag, so that the maximum distance between the outer sides of the limiting component 2 is equal to the width of the packaging bag. Then stack the packaging bags on the workbench 1, and make the first positioning component 3 slide along the workbench 1. During the sliding process, the first positioning component 3 can push the packaging bag to move, so as to center and arrange the packaging bag. The moving distance of the first positioning component 3 is limited by the limiting component 2 to avoid the first positioning component 3 from excessively squeezing the packaging bag. Then start the punching component 4 on the workbench 1. The punching component 4 drives the second positioning component 5 to descend. The second positioning component 5 presses the packaging bag from above to avoid the situation that the packaging bag is driven by the punching component 4 to move downward. At this time, the packaging bag is respectively limited by the second positioning component 5 and the first positioning component 3. The punching component 4 continues to move downward to punch the packaging bag.

[0032] Through the connection between the limiting component 2 and the first positioning component 3 of the present utility model, the limiting component 2 is adjusted to be equal to the width of the packaging bag. The first positioning component 3 moves along the limiting component 2, and the limiting component 2 limits the moving distance of the first positioning component 3. When the first positioning component 3 contacts the limiting component 2, it generates a slight collision and makes a sound, which can remind the staff that the first positioning component 3 has moved in place at this time, avoiding the situation that the first positioning component 3 moves excessively and squeezes the packaging bag. The staff only needs to listen to the sound prompt, which is relatively easy and convenient to use.

[0033] In one embodiment, for the above-mentioned limiting component 2, the limiting component 2 includes a first screw rod 201. A chute 202 is formed on the outer surface of the workbench 1. The first screw rod 201 is rotatably connected inside the chute 202. A first hand wheel 203 is fixedly connected to the end of the first screw rod 201. A limiting block 204 is threadedly connected to the outer surface of the first screw rod 201. The limiting block 204 is slidably connected inside the chute 202. A round hole 205 is formed on the outer surface of the limiting block 204.

[0034] Rotate the first hand wheel 203. The first hand wheel 203 drives the first screw rod 201 to rotate. The first screw rod 201 drives the limiting block 204 to move along the chute 203. The chute 203 can limit the limiting block 204 to avoid unnecessary rotation of the limiting block 204.

[0035] In one embodiment, for the above-mentioned first positioning component 3, the first positioning component 3 includes a second screw rod 301. The second screw rod 301 is rotatably connected inside the chute 202. A second hand wheel 302 is fixedly connected to the end of the second screw rod 301. A sliding baffle 303 is threadedly connected to the outer surface of the second screw rod 301. The sliding baffle 303 is slidably connected to the chute 202. The second screw rod 301 passes through the round hole 205.

[0036] After adjusting the distance between the outer sides of the two groups of limiting blocks 204 to be the same as the width of the packaging bag, rotate the second handwheel 302 to drive the second screw rod 301. The second screw rod 301 drives the sliding baffle 303 to slide along the chute 203. The sliding baffle 303 can push the packaging bag on the workbench 1 to move, centralize and organize the packaging bag. Until the sliding baffle 303 contacts the limiting block 204 and produces a slight collision and makes a sound, the staff can stop rotating the second handwheel 302. At this time, even if the second handwheel 302 continues to rotate, since the sliding baffle 303 is blocked by the limiting block 204, it can avoid excessive movement of the sliding baffle 303 and cause extrusion of the packaging bag.

[0037] In one embodiment, for the above-mentioned punching component 4, the punching component 4 includes a bracket 401, an electric push rod 402 is fixedly connected to the outer surface of the bracket 401, and a punching head 403 is fixedly installed at the movable end of the electric push rod 402.

[0038] In one embodiment, for the above-mentioned second positioning component 5, the second positioning component 5 includes a connecting rod 501. The connecting rod 501 is fixedly connected to the movable end of the electric push rod 402. A spring 502 is fixedly connected inside the connecting rod 501. A sliding rod 503 is slidably connected inside the connecting rod 501. A pressing plate 504 is fixedly connected to the lower end of the sliding rod 503.

[0039] Start the electric push rod 402 to drive the punching head 403 and the connecting rod 501 to move downward. The pressing plate 504 on the connecting rod 501 first contacts the packaging bag and presses and fixes the packaging bag. When the electric push rod 402 continues to descend, the connecting rod 501 can compress the spring 502, and the sliding rod 503 retracts into the connecting rod 501. At the same time, the punching head 403 on the electric push rod 402 completes the punching operation on the packaging bag.

[0040] In one embodiment, for the above-mentioned workbench 1, a collecting component 6 is arranged on the workbench 1.

[0041] In one embodiment, for the above-mentioned collecting component 6, the collecting component 6 includes a slide rail 601. The slide rail 601 is fixedly connected to the bottom of the workbench 1. A collecting box 602 is slidably connected to the outer surface of the slide rail 601. A square groove 603 is formed in the outer surface of the workbench 1.

[0042] The packaging bag waste cut by the punching head 403 passes through the square groove 603 and falls into the collecting box 602. Pulling the collecting box 602 to move along the slide rail 601 can remove it, which is convenient for cleaning the collecting box 602.

[0043] Through the above technical solutions: 1. By connecting the limiting component 2 with the first positioning component 3, the limiting component 2 is adjusted to be equal to the width of the packaging bag. The first positioning component 3 moves along the limiting component 2, and the limiting component 2 restricts the moving distance of the first positioning component 3. When the first positioning component 3 contacts the limiting component 2, a slight collision occurs and a sound is emitted, which can remind the staff that the first positioning component 3 has moved in place at this time, avoiding the situation that the first positioning component 3 moves excessively and squeezes the packaging bag. The staff only needs to listen to the sound prompt, which is relatively easy and convenient to use. 2. By connecting the limiting block 204 with the sliding baffle 303, first adjust the distance between the two limiting blocks 204 so that the distance between the outer sides of the two limiting blocks 204 is the same as the width of the packaging bag. Then push the sliding baffle 303 to rotate. The sliding baffle 303 pushes the packaging bag on the workbench 1 to move and center it. When the sliding baffle 303 contacts the limiting block 204, a slight collision occurs and a sound is emitted, prompting the staff to stop pushing the sliding baffle 303. Even if the sliding baffle 303 is continuously pushed, the sliding baffle 303 is blocked by the limiting block 204 and cannot move, thus avoiding the situation that the sliding baffle 303 moves excessively and squeezes the packaging bag, making it more convenient to use.
