Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cardboard box production and processing technology, specifically a cardboard box punching device with a limiting structure. Background Technology
[0002] Cardboard boxes, as a packaging material, are lightweight, low-cost, easy to process, convenient for storage and transportation, and have a reasonable structure. As a result, they will continue to be the main packaging material for a long time to come. When punching holes in cardboard boxes, holes are usually punched directly on the corrugated cardboard, and in some cases, holes are punched directly on the cardboard box. The former has high production efficiency and is suitable for mass production of standardized hole patterns. In contrast, traditional punching usually involves manual, experience-based placement and positioning, which can easily lead to inaccurate punching positions and the cardboard box can easily slide, thus affecting punching efficiency. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides a cardboard box punching device with a limiting structure, which solves the problem that traditional punching usually relies on manual experience for positioning, which easily leads to inaccurate punching positions and the cardboard can easily slide, thus affecting punching efficiency.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a cardboard box punching device with a limiting structure, including a worktable, a U-shaped platform fixedly installed on the worktable, multiple limiting mechanisms provided on the worktable, a horizontal scale plate connected to the worktable, a vertical scale plate connected to both the worktable and the U-shaped platform, a horizontal slide groove and a vertical slide groove provided on the worktable, and a groove provided below the worktable;
[0005] A motor is fixedly installed on the worktable. The output shaft of the motor is connected to a lead screw. A slider is installed through the lead screw. Connecting frames are connected to both sides of the slider. Pressure plates are connected to the connecting frames. A material discharge port is opened below the U-shaped platform. An electric push rod is fixedly installed above the U-shaped platform. A punching head is installed on the movable end of the electric push rod.
[0006] As a further embodiment of this utility model: the limiting mechanism includes an adjusting screw, one end of which is connected to a handwheel, and the other end of which is rotatably connected to a connecting block, and a baffle is connected to the connecting block.
[0007] As a further embodiment of this utility model: there are two limiting mechanisms, one horizontal and one vertical, and the adjusting screws in the two limiting mechanisms are threadedly connected to the worktable. The connecting blocks in the two limiting mechanisms slide in the horizontal slide groove and the vertical slide groove respectively and are in contact with the groove wall.
[0008] As a further embodiment of this utility model: a support frame is connected below the workbench, a collection box is slidably installed inside the support frame, and a handle is connected to the collection box.
[0009] As a further embodiment of this utility model: the lead screw is rotatably connected to the worktable via a bearing and is located in a groove, the slider slides in the groove, and a mating sleeve is fixedly installed inside the slider, the mating sleeve being threadedly engaged with the lead screw.
[0010] As a further embodiment of this utility model: a rubber pad is connected to one side of the pressure plate, two guide grooves are opened on the worktable, and the two guide grooves are arranged on both sides of the groove. The connecting frame slides in the guide groove and is in contact with the groove wall.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This cardboard punching device with a limiting structure, consisting of a motor, lead screw, slider, groove, mating sleeve, connecting frame, and pressure plate, works by having the adjacent sides of the corrugated cardboard contact and abut against two baffles. The operator starts the motor to rotate the lead screw, causing the slider to slide within the groove through the threaded engagement of the mating sleeve and the lead screw. This sliding of the slider moves the connecting frame within the guide groove, gradually bringing the pressure plate closer to the corrugated cardboard until it comes into contact with it, thus confining the cardboard between the pressure plate and the baffles. This positioning and limiting mechanism prevents accidental slippage and improves punching accuracy.
[0013] 2. This cardboard punching device with a limiting structure includes a handwheel, adjusting screw, connecting block, baffle, horizontal slide, vertical slide, horizontal scale plate, and vertical scale plate. Before placing the corrugated cardboard, the operator rotates the adjusting screw by turning the handwheel, causing the adjusting screw to push the connecting block to move. This causes the baffles in the two limiting mechanisms to move along the horizontal and vertical slides, respectively, thereby changing the distance between the two baffles and the center point of the punching head. The horizontal and vertical scale plates allow the operator to easily observe the moving distance. The two perpendicular baffles position the corrugated cardboard, facilitating placement by the worker. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] like Figure 1-5 As shown, this utility model provides a technical solution: a cardboard box punching device with a limiting structure, including a workbench 1, a U-shaped platform 2 fixedly installed on the workbench 1, and multiple limiting mechanisms 3 provided on the workbench 1. Each limiting mechanism 3 includes an adjusting screw 301, a handwheel 302 connected to one end of the adjusting screw 301, and a connecting block 303 rotatably connected to the other end of the adjusting screw 301. A baffle 304 is connected to the connecting block 303. The handwheel 302 allows the worker to easily turn the adjusting screw 301 to adjust the position of the two baffles 304. The two mutually perpendicular baffles 304 then block and limit the adjacent sides of the corrugated cardboard to prevent rotational deviation.
[0022] There are two limiting mechanisms 3, one horizontal and one vertical. The adjusting screws 301 in both limiting mechanisms 3 are threadedly connected to the worktable 1. The connecting blocks 303 in the two limiting mechanisms 3 slide in the horizontal slide groove 6 and the vertical slide groove 7 respectively and are in contact with the groove walls. Through the contact between the groove walls of the horizontal slide groove 6 and the vertical slide groove 7 and the connecting blocks 303, the connecting blocks 303 can be guided and restricted, preventing the connecting blocks 303 from rotating or tilting during movement.
[0023] A horizontal scale plate 4 is connected to the workbench 1, and a vertical scale plate 5 is connected to both the workbench 1 and the U-shaped table 2. A horizontal slide 6 and a vertical slide 7 are provided on the workbench 1. A support frame 17 is connected below the workbench 1, and a collection box 18 is slidably installed inside the support frame 17. A handle 19 is connected to the collection box 18. Waste material generated from drilling will fall into the collection box 18 from the discharge port 14, thereby collecting the waste material in a concentrated manner through the collection box 18. The handle 19 makes it convenient for workers to pull the collection box 18 to move.
[0024] A groove 8 is provided below the workbench 1. A motor 9 is fixedly installed on the workbench 1. The output shaft of the motor 9 is connected to a lead screw 10. A slider 11 is installed through the lead screw 10. The lead screw 10 is rotatably connected to the workbench 1 via a bearing and is located in the groove 8. The slider 11 slides in the groove 8. A mating sleeve 20 is fixedly installed in the slider 11. The mating sleeve 20 is threadedly engaged with the lead screw 10. By rotating the lead screw 10, the slider 11 slides along the lead screw 10 in the groove 8 via the mating sleeve 20, thereby driving the pressure plate 13 to move. This causes the pressure plate 13 to press and fix the corrugated cardboard, preventing the cardboard from sliding or tilting during punching.
[0025] Connecting frames 12 are connected to both sides of the slider 11, and pressure plates 13 are connected to the connecting frames 12. A material discharge port 14 is opened below the U-shaped platform 2. An electric push rod 15 is fixedly installed above the U-shaped platform 2. A punching head 16 is installed on the movable end of the electric push rod 15. A rubber pad 21 is connected to one side of the pressure plate 13. Two guide grooves 22 are opened on the worktable 1, and the two guide grooves 22 are located on both sides of the groove 8. The connecting frame 12 slides in the guide groove 22 and is in contact with the groove wall. The rubber pad 21 on the pressure plate 13 can increase the friction with the corrugated cardboard, thereby improving the stability of the limit fixation. The contact between the groove wall of the guide groove 22 and the connecting frame 12 can prevent the slider 11 and the connecting frame 12 from rotating and deviating.
[0026] The working principle of this utility model is as follows:
[0027] By turning the handwheel 302 to rotate the adjusting screw 301, the adjusting screw 301 pushes the connecting block 303 to move, causing the baffles 304 in the two limiting mechanisms 3 to move along the horizontal slide groove 6 and the vertical slide groove 7 respectively, thereby changing the distance between the two baffles 304 and the center point of the punch head 16. The horizontal scale plate 4 and the vertical scale plate 5 allow the operator to easily observe the movement distance of the two baffles 304. Then, the adjacent sides of the corrugated cardboard are brought into contact with the two baffles 304, and then the motor 9 is started to drive the lead screw 10 to rotate. This causes the slider 11 to slide along the lead screw 10 in the groove 8 via the sleeve 20, which in turn causes the slider 11 to drive the connecting frame 12 to move in the guide groove 22, causing the pressure plate 13 to gradually approach the corrugated cardboard until the pressure plate 13 and the corrugated cardboard are in contact, thereby restricting the corrugated cardboard between the pressure plate 13 and the baffle 304. Then, the electric push rod 15 is activated to push down the punching head 16, so that the punching head 16 contacts the corrugated cardboard to complete the punching work. The waste generated by punching can fall from the discharge port 14 into the collection box 18 for centralized collection.
