Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bag production, and more specifically, particularly relates to a punching device for processing plastic packaging bags. Background Art

[0002] Packaging bags refer to bags used to package various supplies, which make it convenient to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. The commodity nature of the packaging itself is becoming more and more obvious. It has become a special product that is no longer dependent on commodity production. It is a product that all commodities cannot do without and is widely used.

[0003] The existing publication number CN217021604U discloses a punching device for processing plastic packaging bags. Although the punching position of the packaging bag can be pressed and fixed by setting a second electric push rod and a clamping ring to prevent the packaging bag from shifting during the punching process and ensure the quality of the punching process, a waste box is set to collect the waste generated by punching to avoid subsequent manual cleaning of the waste. A slider and a slide groove are set to facilitate the sliding of the waste box, thereby improving the convenience of operation.

[0004] Based on the above, the inventors found that the following problems exist: However, the second electric push rod is used for pressing, which results in the need to wait for the second electric push rod to press the packaging bag before punching, and then perform the remaining work, and the second electric push rod needs to be retracted after punching, resulting in the punching efficiency of the device being too low. Existing packaging bags are generally transported to the bottom of the punching machine by rollers, and the rollers transport them through friction, while the friction of plastic packaging bags is generally low, and they are prone to slipping, resulting in offset during punching.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a punching device for processing plastic packaging bags is provided, in order to achieve a more practical purpose. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a punching device for processing plastic packaging bags to solve the problems that the current punching efficiency is too low and the friction of plastic packaging bags is generally low, which is easy to slip and cause deviation during punching.

[0007] The utility model provides a punching device for processing plastic packaging bags, which is achieved by the following specific technical means:

[0008] A punching device for processing plastic packaging bags comprises a bottom plate, support columns are fixed to the four corners of the top of the bottom plate, a top plate is fixed to the top of the support columns, a reciprocating hydraulic telescopic rod is fixed to the middle of the bottom of the top plate, a sleeve block is fixed to the power output end of the reciprocating hydraulic telescopic rod, a telescopic block is movably sleeved on the bottom of the sleeve block, a first spring and a connecting rod are fixed to the top of the inner wall of the sleeve block, a connecting disk is fixed to the bottom of the connecting rod, a punching head is arranged at the bottom of the connecting disk, and a punching table is fixed to the middle of the top of the bottom plate.

[0009] Furthermore, the top of the first spring is fixed to the top of the inner wall of the sleeve block, the bottom of the first spring is fixed to the top of the telescopic block, and the height of the connecting rod is greater than the height of the telescopic block.

[0010] Furthermore, a slide groove is formed through one side of the support column, a slider is slidably connected inside the slide groove, and a driven roller is rotatably connected to one side of the slider.

[0011] Furthermore, a fixed plate is fixed on one side of the support column, a second spring is fixed on the bottom of the fixed plate, and a bottom end of the second spring is fixed to the movable plate.

[0012] Furthermore, a micro servo motor is fixed on one side of the support column, a driving roller is fixed on the power output end of the micro servo motor, and the driving roller and the driven roller are in contact with each other.

[0013] Furthermore, a connecting bolt is threadedly connected through the middle of the inner wall of the punching head, and the connecting bolt is threadedly connected to the connecting plate. The middle cross-section of the bottom of the punching head is in the shape of an isosceles trapezoid.

[0014] Furthermore, a collecting groove is formed through one side of the punching platform, and a hole is formed through the top of the punching platform, wherein the diameter of the hole is smaller than the diameter of the connecting disk.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. In the utility model, the sleeve block is driven by a reciprocating hydraulic telescopic rod, and the telescopic block is supported by a first spring, so that when not subject to external force, the bottom end of the telescopic block can be located at the bottom of the punching head, so that when punching, the telescopic block can touch the plastic packaging bag at the bottom before the punching head, and the plastic packaging bag is squeezed by the telescopic block. At this time, the reciprocating hydraulic telescopic rod drives the sleeve block to continue to move downward, and the telescopic block is first used for squeezing and then punching through the punching head, so as to move together with the punching device, limit the plastic packaging bag before punching, and achieve the effect of limiting while reducing the impact on work efficiency.

[0017] 2. In the utility model, the elastic potential energy is released by the second spring. When plastic packaging bags of different thicknesses pass through the middle of the active roller and the driven roller, the active roller and the driven roller are always in contact with each other. At the same time, the second spring keeps the driven roller in contact with the active roller, so that the squeezing force between the driven roller, the active roller and the plastic packaging bag is increased, thereby increasing the friction force, thereby achieving the effect of reducing the possibility of slipping of the plastic packaging bag during feeding.

[0018] 3. In the present invention, when it is necessary to replace a punching head of a different size, the connecting bolts are removed, a new punching head is placed at the bottom of the connecting plate, and the punching head is fixed by the connecting bolts, thereby achieving a more convenient effect of replacing the punching head.

[0028] As attached Figure 1 To Attachment Figure 4 As shown:

[0029] The utility model provides a punching device for processing plastic packaging bags, comprising a bottom plate 1, support columns 2 are fixed to the four corners of the top of the bottom plate 1, a top plate 3 is fixed to the top of the support column 2, a reciprocating hydraulic telescopic rod 4 is fixed to the middle of the bottom of the top plate 3, a sleeve block 5 is fixed to the power output end of the reciprocating hydraulic telescopic rod 4, a telescopic block 6 is movably sleeved at the bottom of the sleeve block 5, a first spring 7 and a connecting rod 8 are fixed to the top of the inner wall of the sleeve block 5, a connecting disk 9 is fixed to the bottom of the connecting rod 8, a punching head 10 is arranged at the bottom of the connecting disk 9, and a punching table 12 is fixed to the middle of the top of the bottom plate 1.

[0030] Among them, the top of the first spring 7 is fixed to the top of the inner wall of the sleeve block 5, the bottom of the first spring 7 is fixed to the top of the telescopic block 6, the height value of the connecting rod 8 is greater than the height value of the telescopic block 6, and the telescopic block 6 is supported by the first spring 7, so that when not subject to external force, the bottom end of the telescopic block 6 can be located at the bottom of the punching head 10, so that when punching, the telescopic block 6 can touch the plastic packaging bag at the bottom before the punching head 10, and the plastic packaging bag is squeezed through the telescopic block 6. At this time, the reciprocating hydraulic telescopic rod 4 drives the sleeve block 5 to continue to move downward, and the telescopic block 6 is used for squeezing first and then the punching head 10 is used for punching.

[0031] Among them, a slide groove 15 is opened through one side of the support column 2, a slider 16 is slidably connected inside the slide groove 15, and a driven roller 20 is rotatably connected to one side of the slider 16. A fixed plate 18 is fixed on one side of the support column 2, and a second spring 19 is fixed at the bottom of the fixed plate 18. The bottom end of the second spring 19 is fixed to the movable plate 17. The second spring 19 provides elastic potential energy so that the driven roller 20 is always in contact with the active roller 21.

[0032] Among them, a micro servo motor 22 is fixed on one side of the support column 2, and an active roller 21 is fixed to the power output end of the micro servo motor 22. The active roller 21 and the driven roller 20 are fitted together, and the elastic potential energy is released through the second spring 19. When plastic packaging bags of different thicknesses pass through the middle of the active roller 21 and the driven roller 20, the active roller 21 and the driven roller 20 are always fitted together. At the same time, the second spring 19 keeps the driven roller 20 in fit with the active roller 21, so that the extrusion force between the driven roller 20 and the active roller 21 and the plastic packaging bag is increased, thereby increasing the friction.

[0033] Among them, a connecting bolt 11 is threadedly connected through the middle of the inner wall of the punching head 10, and the connecting bolt 11 is threadedly connected to the connecting disk 9. When the punching head 10 of a different size needs to be replaced, the connecting bolt 11 is removed, and the new punching head 10 is placed at the bottom of the connecting disk 9, and the punching head 10 is fixed by the connecting bolt 11. The middle cross-section of the bottom of the punching head 10 is an isosceles trapezoidal shape, which can better avoid excessive plastic packaging bag punching waste at the punching head 10 after punching.

[0034] Among them, a collecting groove 13 is opened through one side of the punching platform 12, and a hole 14 is opened through the top of the punching platform 12. The diameter of the hole 14 is smaller than the diameter of the connecting plate 9 to prevent the connecting plate 9 from slipping out of the hole 14. The collecting groove 13 can collect the packaging bag waste after punching.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In the utility model, a punching head 10 of corresponding size is first selected, and the punching head 10 is fixed by connecting bolts 11, and then one end of the packaging bag passes between one of the active rollers 21 and the driven roller 20, and then passes between the other active roller 21 and the driven roller 20, and the micro servo motor 22 is started to drive the active roller 21 to rotate, and the elastic potential energy is released by the second spring 19. When plastic packaging bags of different thicknesses pass through the middle of the active roller 21 and the driven roller 20, the active roller 21 and the driven roller 20 are always in contact, and at the same time, the second spring 19 is always in contact with the driven roller 20, so that the driven roller 20 and the active roller 21 are in contact with the plastic packaging bag. The extrusion force increases, and the friction force increases, so that the packaging bag is always in a taut state and is located on the top of the punching table 12. The reciprocating hydraulic telescopic rod 4 is controlled to drive the sleeve block 5 to move downward, and the telescopic block 6 is supported by the first spring 7, so that when not subject to external force, the bottom end of the telescopic block 6 is located at the bottom of the punching head 10. When punching, the telescopic block 6 can touch the plastic packaging bag at the bottom before the punching head 10, and the plastic packaging bag is squeezed by the telescopic block 6. At this time, the reciprocating hydraulic telescopic rod 4 drives the sleeve block 5 to continue to move downward, and the telescopic block 6 is used for squeezing first, and then the punching head 10 is used for punching. After punching, the collection tank 13 collects the waste packaging bag after punching.
