Description

Technical Field

[0001] The utility model relates to the technical field of hole pressing devices, and particularly relates to a high-frequency hole pressing device. Background Art

[0002] Plastic bags are generally used to hold various items. During the use and production of plastic bags, it is necessary to punch holes in them to prevent the excess air in the plastic bags from being difficult to discharge. Therefore, a punching machine is generally used to punch the vertices of plastic bags. Therefore, an existing high-frequency hole pressing device has been continuously innovated and developed. It can be seen that the current hole pressing device basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the publication number CN219446278U discloses: "A punching device for plastic bag production, which relates to the technical field of plastic bag processing equipment, includes a base and a waste collection box. A through hole is opened at the top of the base. The base is fixedly connected to a cylinder bearing seat through brackets welded to the front and back. The top of the cylinder bearing seat is fixedly connected to a cylinder. The bottom of the cylinder is fixedly connected to a hole opener bracket. The hole opener bracket is fixedly connected to a sleeve. The sleeve is sleeved with a top column inside it, and a baffle is arranged inside the sleeve. A retaining ring is arranged on the side of the top column. The bottom of the retaining ring is fixedly connected to a spring. A cutter is sleeved inside the sleeve. In this device, the cutter punches a hole in the plastic bag under the push of the cylinder. After the cutter contacts the rubber pad on the step surface through the through hole arranged on the base, the top column inside the cutter presses down against the spring pressure, and the cut plastic bag debris is pushed into the waste collection box", and the automatic feeding and material collection are realized by driving the material collection cylinder with a motor, improving the production rate. Under the push of the cylinder, the hole opener connected to the hole opener bracket presses down. After cutting the plastic bag and continuing to press down, when the cutter enters the through hole arranged on the base and contacts the rubber pad on the step surface of the through hole, the cutter stops moving. The rubber pad can reduce the probability of damage to the cutting edge of the cutter during the pressing process.

[0004] However, the cylinder of the above device consumes a high amount of funds, resulting in a high usage cost when used for punching plastic bags. Moreover, the telescopic speed of the cylinder during use is slow, leading to poor efficiency in punching plastic bags. Therefore, a galvanized square pipe bracket with adjustable height is needed to solve the above problems. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 、 Figure 3 and Figure 4 , a high-frequency hole-pressing device:

[0025] It includes: a machine body 1, an operation box 2 is fixedly connected to the front of the machine body 1, a first driving motor 3 is fixedly connected to the inner wall of the machine body 1, a driving rod 4 is installed at the output end of the first driving motor 3, and the surface of the driving rod 4 is rotatably connected to the inner walls of the machine body 1 and the operation box 2. A cam 5 is fixedly connected to the middle of the surface of the driving rod 4. A telescopic column 6 is slidably connected to the inner bottom wall of the operation box 2. On the left and right sides of the top of the telescopic column 6, connection plates 7 are fixedly connected. A spring 8 is fixedly connected to the bottom of the connection plate 7, and the bottom end of the spring 8 is connected to the inner wall of the operation box 2. The top of the telescopic column 6 is rotatably connected to a runner 9, and the top of the runner 9 abuts against the side of the cam 5. A screw rod 10 is threadedly connected to the inner wall of the bottom end of the telescopic column 6. A hole-pressing rod 11 is fixedly connected to the bottom end of the screw rod 10. A workbench 12 is fixedly connected to the bottom of the front of the machine body 1.

[0026] When punching holes in a plastic bag through the hole-pressing rod 11, place the plastic bag on the top of the workbench 12 so that the position to be punched is in the middle of the top of the workbench 12. Then, connect the first driving motor 3 to the power supply, so that the output end of the first driving motor 3 drives the driving rod 4 to rotate. The driving rod 4 drives the cam 5 on its surface to rotate, so that the cam 5 drives the runner 9 at the bottom to rotate, and the cam 5 at different positions presses the runner 9, so that the runner 9 drives the telescopic column 6 at the bottom to slide downward. At this time, the telescopic column 6 drives the connection plate 7 to compress the spring 8, so that the runner 9 always contacts the cam 5. Then, the telescopic column 6 drives the screw rod 10 at the bottom to move up and down. The screw rod 10 drives the hole-pressing rod 11 at the bottom to move up and down and press on the plastic bag to punch holes in the plastic bag. The rotation speed of the output end of the first driving motor 3 is different, so that the pressing frequency of the hole-pressing rod 11 is different.

[0027] Please refer to Figure 1 and Figure 2 , a stacking box 13 is slidably connected to the inner wall of the front of the workbench 12. A handle 14 is fixedly connected to the front of the stacking box 13. A hole-pressing plate 15 is lapped on the top of the workbench 12. Pulling rods 16 are fixedly connected to the left and right sides of the inner wall of the hole-pressing plate 15.

[0028] When punching holes of different sizes in a plastic bag through this device, you can hold the pulling rod 16 and pull it upward, so that the hole-pressing plate 15 is separated from the workbench 12. Then, place the hole-pressing plates 15 with holes of different sizes on the workbench 12. Then, rotate the screw rod 10 so that the screw rod 10 is separated from the telescopic column 6. Then, replace the hole-pressing rod 11 with a corresponding size hole-pressing rod 11 to facilitate punching holes of different sizes in plastic bags of different sizes.

[0029] Please refer to Figure 1 and Figure 5, connection shells 17 are fixedly connected to the ends on both the left and right sides of the workbench 12. A second drive motor 18 is fixedly connected to the inner wall of the connection shell 17. A rotating rod 19 is installed at the output end of the second drive motor 18. The front and rear ends of the rotating rod 19 are rotatably connected to the inner wall of the workbench 12. A drive gear 20 is fixedly connected to the surface of the rotating rod 19. An engaging gear 21 is meshed with the surface of the drive gear 20. A connecting rod 22 is fixedly connected to the inner wall of the engaging gear 21. The front and rear ends of the connecting rod 22 are rotatably connected to the inner wall of the workbench 12. A first rotating roller 23 is fixedly connected to the front end of the rotating rod 19. The rear end of the first rotating roller 23 is rotatably connected to the inner wall of the workbench 12. A second rotating roller 24 is fixedly connected to the front end of the connecting rod 22. The rear end of the second rotating roller 24 is rotatably connected to the inner wall of the workbench 12.

[0030] When transporting a plastic bag through this device, the second drive motor 18 is powered on, causing the rotating rod 19 at its output end to rotate. The rotating rod 19 drives the drive gear 20 on its surface to rotate. The drive gear 20 drives the engaging gear 21 on its surface to rotate. The engaging gear 21 drives the connecting rod 22 on its inner wall to rotate. At this time, the rotating rod 19 drives the first rotating roller 23 to rotate, and the connecting rod 22 drives the second rotating roller 24 to rotate. Then, the plastic bag is flattened and passed through the gap between the middle parts of the first rotating roller 23 and the second rotating roller 24, and the first rotating roller 23 and the second rotating roller 24 drive the plastic bag to move towards the top of the workbench 12. Then, the plastic bag is passed through the gap between the middle parts of the first rotating roller 23 and the second rotating roller 24 on the right side of the workbench 12, and the two groups of rotating rollers drive the plastic bag to be transported to one side.

[0031] Working principle: Hold the pull rod 16 and remove the hole-pressing disc 15. Place the hole-pressing disc 15 of the corresponding hole on the top of the workbench 12. Then rotate the screw rod 10 to make the screw rod 10 disengage from the fixed telescopic column 6. Then fix the corresponding hole-pressing rod 11 and the screw rod 10 to the inner wall of the telescopic column 6. Subsequently, the second drive motor 18 is powered on, causing its output end to drive the first rotating roller 23 and the second rotating roller 24 to rotate. Then, the plastic bag is passed through the gap between the middle parts of the rotating rollers on the left side of the workbench 12 and transported. Then, the plastic bag is passed through the gap between the middle parts of the rotating rollers on the right side of the workbench 12 and transported. Subsequently, the first drive motor 3 is powered on, causing it to drive the telescopic column 6 to move up and down telescopically. Thus, the telescopic column 6 drives the hole-pressing rod 11 at its bottom end to move up and down, and the hole-pressing rod 11 moves up and down to press holes in the plastic bag. The plastic bag scraps generated when pressing the holes fall into the accumulation box 13, facilitating pulling out the accumulation box 13 for centralized processing.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
