Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a punching device for processing packaging bags. Background Art

[0002] The function of the punching device for processing packaging bags is to accurately and efficiently punch the required holes in the packaging bags according to preset requirements and positions to meet various needs in the subsequent use of the packaging bags, such as ventilation, threading, easy opening and closing, etc.;

[0003] The existing Chinese patent (publication number CN220785073U) discloses a punching device for processing packaging bags. The packaging bag is laid on the placement plate and the workbench, and the position of the packaging bag to be punched is made to correspond to the through groove on the placement plate. First, the electric hydraulic cylinder A drives the limiting ring to tightly limit the periphery of the position of the packaging bag to be punched on the placement plate. Then, by starting the electric hydraulic cylinder B, the punching knife is driven to punch the packaging bag. The waste material of the punched packaging bag is collected into the aggregate box through the blanking groove. Then, the electric hydraulic cylinder B and the electric hydraulic cylinder A are reset in sequence, and the above operations are repeated to realize the tight limiting of the periphery of the position to be punched of packaging bags of different sizes, avoiding a series of adjustment and pressing operations before punching packaging bags of different sizes and achieving the technical effect of not being convenient for quickly punching packaging bags of different sizes continuously;

[0004] The above patent solves the problem that it is not convenient to quickly punch packaging bags of different sizes continuously in the prior art. Before punching, the limiting ring in the pressing component tightly limits the periphery of the position of the packaging bag to be punched, reducing the movement of the packaging bag during punching. Then, the punching knife is driven by the electric hydraulic cylinder B to perform the punching action, realizing the tight limiting of the periphery of the position to be punched of packaging bags of different sizes;

[0005] However, in actual use, since the limiting ring in the above patent is connected to the bottom of the fixed plate B by threads, although the threaded connection is relatively stable, during the actual downward pressing process, when the punching knife contacts the raw material, a large impact force and frictional force may be generated. This impact force and frictional force act on the limiting ring instantaneously. If the pressing force is not strong enough or the threaded connection becomes loose after long-term use, it may not be able to effectively fix the raw material, resulting in the movement of the raw material under the action of the punching knife.

[0006] Therefore, the utility model proposes a punching device for processing packaging bags. Summary of the Utility Model

[0013] As a preferred embodiment, a threaded column is rotatably connected to the bottom plate, and the threaded column on the bottom plate is threadedly connected to the clamping plate.

[0014] The technical effect of adopting the above further scheme is that by providing a shrapnel, the shrapnel can form a vibration force when the punching knife retracts, so that the waste stuck on the bottom plate can be shaken off to avoid blockage.

[0015] As a preferred embodiment, a shrapnel is fixedly connected to the bottom of the bottom plate, and one side of the shrapnel away from the bottom plate is fixedly connected to the base.

[0017] As a preferred embodiment, the air pump is fixedly communicated with the air chamber, a connecting member is fixedly connected to the air pump, and the connecting member is fixedly connected to the base.

[0018] The technical effect of adopting the above further solution is that by setting the air pump to be fixedly communicated with the air chamber, it is convenient to change the air pressure in the air chamber.

[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

This effectively avoids the displacement of the raw material at the moment of punching, thereby improving the punching accuracy and quality, and reducing the punching deviation and waste caused by the movement of the raw material.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] This embodiment provides a technical solution, as Figures 1 to 4 shown, a punching device for packaging bag processing, including a base 1, and a pressing assembly 2 is arranged on the base 1;

[0034] The pressing assembly 2 includes a gear 21, a second rotating shaft 23 is rotatably connected to the gear 21, a tooth block 29 is meshed and connected to the gear 21, a connecting block 24 is rotatably connected to the second rotating shaft 23, an arc-shaped connecting piece 25 is fixedly connected to the connecting block 24, a clamping plate 26 is fixedly connected to the arc-shaped connecting piece 25, a base plate 3 is arranged at the bottom of the clamping plate 26, and a dial 28 is fixedly connected to the base plate 3;

[0035] A sliding column 35 is fixedly connected to the base 1, a sliding plate 32 is slidably connected to the sliding column 35, a piston rod 41 is fixedly connected to the sliding plate 32, an air chamber 4 is slidably connected to the piston rod 41, a fixed plate 33 is fixedly connected to the air chamber 4, an air pump 34 is fixedly connected to the fixed plate 33, and a punch head 42 is fixedly connected to one end of the sliding plate 32 away from the fixed plate 33;

[0036] In the present invention, the raw material is initially clamped by the threaded column, and then the clamping force is enhanced by the linkage of the clamping mechanism when the air pump 34 drives the punch head 42 to punch holes. When punching downwards, the arc-shaped connecting piece 25 can drive the clamping plate 26 to move downwards, which can ensure that the raw material can still be stably clamped at the moment of punching during the punching process. This effectively avoids the displacement of the raw material at the moment of punching, thereby improving the punching accuracy and quality, and reducing the punching deviation and waste product generation caused by the movement of the raw material.

[0037] Furthermore, as Figure 3 . Figure 4As shown in the figure, a first rotating shaft 22 is rotatably connected to the gear 21, the first rotating shaft 22 is rotatably connected to the base 1, a receiving layer 12 is fixedly connected to the tooth block 29, the receiving layer 12 is slidably connected within the base 1, a paddle 28 is slidably connected to the tooth block 29, a connecting block 24 is slidably connected to the base 1. When the gear 21 rotates, it can drive the connecting block 24 to move. An arc-shaped connecting piece 25 is fixedly connected to the connecting block 24, and the arc-shaped connecting piece 25 is fixedly connected to the clamping plate 26. The clamping plate 26 is connected to the bottom plate 3 through a threaded column. When the gear 21 rotates, it can drive the clamping plate 26 to move up and down. Also, because the connecting block 24 is slidably connected to the base 1, it plays a certain limiting role in the movement of the connecting block 24;

[0038] A threaded column is rotatably connected to the bottom plate 3, and the threaded column on the bottom plate 3 is threadedly connected to the clamping plate 26. By providing a spring piece 27, the spring piece 27 can cause the bottom plate 3 to form a vibration force when the punching tool retracts, so that the waste material stuck on the bottom plate 3 can be shaken off to avoid blockage;

[0039] A spring piece 27 is fixedly connected to the bottom of the bottom plate 3, and one side of the spring piece 27 away from the bottom plate 3 is fixedly connected to the base 1. By providing an air pump 34, during use, by starting the air pump 34, the air pump 34 sends air into the air chamber 4, so that the piston rod 41 is pushed out under the action of air pressure, and the piston rod 41 drives the sliding plate 32 to slide downward on the sliding column 35, so that the punching tool contacts the workpiece.

[0040] In the above solution, there is also a problem that the power source of the sliding plate 32 is not proposed, such as Figures 1 to 4 As shown in the figure, the air pump 34 is fixedly connected and communicated with the air chamber 4, a connecting piece 13 is fixedly connected to the air pump 34, and the connecting piece 13 is fixedly connected to the base 1. By providing that the air pump 34 is fixedly connected and communicated with the air chamber 4, it is convenient to change the air pressure in the air chamber 4;

[0041] A convex block is fixedly connected to the punch 42, a sliding frame is fixedly connected within the base 1, and the sliding frame on the base 1 is slidably connected to the paddle 28. By providing a sliding frame within the base 1, the limit of the paddle 28 is realized.

[0042] Working principle:

[0043] Such as Figures 1-4As shown in the figure: When in use, first place the raw material between the bottom plate 3 and the clamping plate 26. By externally twisting the threaded column threadedly connected to the clamping plate 26, the clamping plate 26 moves towards the bottom plate 3 to achieve the preliminary clamping of the raw material. After that, by starting the air pump 34, the air pump 34 conveys air into the air chamber 4, causing the piston rod 41 to be pushed out, the sliding plate 32 to be pushed downward, and the punch 42 to move downward to punch the raw material. When the punch 42 moves downward, the convex block on the punch 42 contacts the clamping plate 26, and the clamping plate 26 moves downward. The dial 28 will be driven to move the gear block 29, causing the gear 21 to rotate slightly, the connecting block 24 to be driven to move up and down, and the clamping plate 26 to be driven to move downward by the arc-shaped connecting piece 25, so that the clamping force between the clamping plate 26 and the bottom plate 3 instantaneously increases.

[0044] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
