Description

Technical Field

[0001] The utility model relates to the field of packaging bag processing, in particular to a high-speed punching mechanism for packaging bags. Background Technique

[0002] A packaging bag is a container for packaging various items. They are usually made of plastics, papers, fibers, fabrics or composite materials, and can be made into bags of different shapes and sizes through various bag-making processes to meet different packaging needs.

[0003] In the processing process, raw materials such as plastic films, papers, aluminum foils, etc. need to be processed through a series of processing techniques to be made into bag-shaped products for packaging different commodities. Before the packaging bags are cut into individual bags after several layers of films are laminated together, they are in a long strip shape. At this time, it is necessary to punch holes at intervals on the bag surface and then cut, which requires a punching mechanism.

[0004] When the existing punching mechanism punches the packaging bag, it usually punches the packaging bag on the conveyor belt, and the conveyor needs to stop during punching. The response speed of the conveyor is limited, which greatly limits the punching mechanism. When the punching speed is too fast, it is easy to make the start-stop speed of the conveyor inconsistent with the punching speed. Therefore, when the punch has not yet risen, the bag may move forward, resulting in the situation of pulling the bag on the punch, which greatly affects the punching efficiency.

[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] Refer to Figures 1-3 , Figure 6 , an embodiment provided by the present invention: A high-speed punching mechanism for packaging bags, including a rail 1, the rail 1 is installed on the side plates of both sides of the transport machine through bolts. The transport machine is used to transport the packaging bags during the processing, which is a well-known prior art to those skilled in the art, so no more details will be described here. A support plate 3 is slidably connected to the inner wall of the rail 1. The bottom end of the support plate 3 is detachably installed on the outer wall of the rail 1 through a limiting mechanism 2. The limiting mechanism 2 limits the current position of the support plate 3 to prevent it from moving along the rail 1. A baffle 4 is fixedly connected to the inner side wall of the support plate 3. The baffle 4 plays a role in protecting the internal punching mechanism components. The inner wall of the support plate 3 is connected to a punch 11 through a transmission mechanism 9. The transmission mechanism 9 includes a slide block 98. The middle part of the slide block 98 is a cylinder, and flat grooves are provided at the upper and lower diagonal corners of the slide block 98. An inclined groove 91 is provided on the inner wall of the support plate 3. The inclination angle of the inclined groove 91 with respect to the horizontal plane of the rail 1 is 35°, and the inclined direction is the same as the transport direction of the transport machine for transporting the packaging bags. The inner wall of the flat groove provided at the diagonal corner of the slide block 98 is slidably connected to the inner wall of the inclined groove 91. By providing the flat groove, it can be avoided that the slide block 98 rotates on the inner wall of the inclined groove 91, so as to ensure that its current angle does not change.

[0034] Refer to Figures 2-5, the transmission mechanism 9 further includes a motor 95 which is the power source for the punching opening. The motor 95 is fixedly connected to the inner side wall of the support plate 3 by bolts. The output shaft of the motor 95 is fixedly connected with a first transmission gear 93. A second transmission gear 94 is meshed with the bottom of the first transmission gear 93. A first turntable 96 is fixedly connected to the center of the second transmission gear 94. The connecting shaft between the second transmission gear 94 and the center of the first turntable 96 is rotatably connected to the inner wall of the support plate 3. By driving the first transmission gear 93 to rotate by the motor 95, the second transmission gear 94 and the first turntable 96 are driven to rotate at the same time. A movable rod 97 is rotatably connected to the side wall of the first turntable 96. The other end of the movable rod 97 is rotatably connected to a fixed rod 92. The other end of the movable rod 97 is sleeved on the outer wall of the fixed rod 92, so that the movable rod 97 can rotate along the outer wall of the fixed rod 92. One end of the fixed rod 92 is fixedly connected to the side wall of the slider 98, and the other end of the fixed rod 92 is fixedly connected to the end side wall of the punch 11. The punch 11 and the slider 98 can be driven to move synchronously through the fixed rod 92.

[0035] Referring to Figure 1 and Figure 3 , the limiting mechanism 2 includes a limiting plate 22. The cross section of the limiting plate 22 is L-shaped. The side wall of the limiting plate 22 is fixedly connected to the outer plate of the support plate 3. A limiting rod 24 penetrates and is slidably connected to the inner wall of the limiting plate 22. A plurality of groups of limiting grooves 21 are formed on the outer wall of the track 1. A return spring 23 is fixedly connected to the inner wall of the protruding part at the outer end of the limiting rod 24. The other end of the return spring 23 is fixedly connected to the outer side wall of the limiting plate 22. The elasticity of the return spring 23 can play a preliminary limiting role on the limiting rod 24. The inner end of the limiting rod 24 is clamped on the inner wall of the limiting groove 21, and it is always kept in a clamped state with the limiting groove 21 under the action of the elasticity of the return spring 23 without being affected by external forces.

[0036] Referring to Figure 1 and Figure 3, a punching component 8 is also slidably connected to the inner wall of the track 1. The difference between the punching component 8 and the above-mentioned device is that it lacks a motor 95 and a first transmission gear 93, and other structures remain the same. The punching component 8 is detachably installed on the outer wall of the support plate 3 through a connection mechanism. The connection mechanism includes two groups of second turntables 13. The center of the second turntable 13 is fixedly connected to the center of the second transmission gear 94. The second transmission gear 94 can drive the second turntable 13 to rotate. Another group of second turntables 13 is arranged on the punching component 8. A first connecting rod 5 is rotatably connected to the outer wall of the second turntable 13. A threaded groove is provided at the outer end of the first connecting rod 5. A threaded sleeve 10 is threadedly connected to the outer end of the first connecting rod 5. The right end of the threaded sleeve 10 is rotatably connected to a second connecting rod 12. The right end of the second connecting rod 12 is rotatably connected to the outer wall of the second turntable 13 on the outside of the punching component 8. When the two groups of second turntables 13 are connected by the first connecting rod 5, the threaded sleeve 10, and the second connecting rod 12, when one group of second turntables 13 rotates, it can drive the other group of second turntables 13 to rotate synchronously. A moving plate 6 is also slidably connected to the inner wall of the track 1. A connecting sleeve 7 is slidably connected to the outer wall of the moving plate 6 in the vertical direction. The outer end of the connecting sleeve 7 is slidably connected to the outer wall of the first connecting rod 5, preventing the first connecting rod 5 from tilting during movement and ensuring its horizontal state. The moving plate 6 is detachably installed on the inner wall of the track 1 through a limiting mechanism 2.

[0037] Working principle: When punching, the motor 95 is used to drive the first transmission gear 93 to rotate, so that the first transmission gear 93 drives the second transmission gear 94 to rotate. The second transmission gear 94 drives the first turntable 96 to rotate. The first turntable 96 drives one end of the movable rod 97 to move along the circumferential center of the first turntable 96. The other end of the first turntable 96 will drive the fixed rod 92 to move. The fixed rod 92 will drive the slider 98 to move along the track of the inclined groove 91, so as to drive the punch 11 to reciprocate along the track of the inclined groove 91. When the punch 11 moves downward, the conveyor stops at this time to punch the packaging bag. When the punch 11 moves away from the packaging bag after punching, its initial moving state is the same as the transportation direction of the packaging bag and moves obliquely upward. At this time, when the packaging bag moves, it can make the packaging bag and the punch 11 relatively stationary in the horizontal state to a certain extent, and move away from each other in the vertical state, avoiding the situation where the bag moves forward when the punch 11 has not been lifted due to too fast punching speed, causing the situation of pulling the bag.

[0038] When simultaneous punching is required, the limiting rod 24 can be moved outward to disengage it from the limiting groove 21. At this time, the support plate 3 and the punching assembly 8 can be moved, and the first connecting rod 5 and the threaded sleeve 10 can be docked. By rotating the threaded sleeve 10, it is connected to the first connecting rod 5. After connection, the limiting rod 24 is reinserted into the limiting groove 21 to limit the distance therebetween, and the distance can be adjusted by rotating the threaded sleeve 10. At this time, when the second transmission gear 94 rotates, it will drive one end of the first connecting rod 5 to move along the center circumference of the second turntable 13, and drive the end of the second connecting rod 12 at the other end to produce synchronous movement, so as to drive the second turntable 13 on the punching assembly 8 to rotate, enabling the passing packaging bags to be punched twice synchronously, greatly improving the punching efficiency without adding an additional motor drive.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
