[0003] The packaging bag side punching processing equipment is a special equipment for punching holes on the side of packaging bags, which is designed to give packaging bags the functions of breathability, drainage and connection. This equipment expands the functional application scenarios of packaging bags and promotes the development of the packaging industry.

[0004] In traditional punching equipment, punching tools experience wear and heat generation due to friction with packaging bag materials after prolonged continuous operation, affecting the shape and dimensional accuracy of the punched holes.

A filter element 207 is fixedly connected to the inner wall of the filter cartridge 203. The filter element 207 performs the dust filtration work.

[0034] Feeding mechanisms 4 are provided on both the left and right sides of the front side of the mounting plate 13. The feeding mechanisms 4 are responsible for conveying the packaging bag to the punching position. Each feeding mechanism 4 includes a feeding roller 401, which drives the packaging bag forward. The rear side of the outer wall of the feeding roller 401 is rotatably connected to the left side of the mounting plate 13, providing rotational support for the feeding roller 401. A discharge roller 403 is rotatably connected to the right side of the mounting plate 13, assisting in dispensing the punched packaging bag. The front and rear sides of the outer walls of the discharge roller 403 and the feeding roller 401 are fixedly connected. A limit ring 402 is connected to prevent the packaging bag from shifting left or right during the conveying process. Two fixing blocks 404 are fixedly connected to the top left and right sides of the operating table 7. The fixing blocks 404 are used to install the pressing shaft 405. The pressing shaft 405 is fixedly connected to the adjacent side of the two fixing blocks 404 on the left and the two fixing blocks 404 on the right. The pressing shaft 405 plays a role in pressing down and guiding the packaging bag. A drive component 5 is provided on the rear side of the feeding mechanism 4. The drive component 5 provides power to the feeding mechanism 4.

[0035] Drive assembly 5 includes two first transmission gears 501, which transmit power. The front sides of the two first transmission gears 501 are fixedly connected to the rear ends of the corresponding feeding roller 401 and discharging roller 403, respectively, to achieve power transmission.

The tracks 504 ensure stable power transmission. A punching mechanism 6 is provided on the top of the base 1 for punching holes. Mechanism 6 performs the punching operation. The punching mechanism 6 includes a punching base 601, which fixes the relevant components of the punching mechanism 6. The bottom of the punching base 601 is fixedly connected to the top of the base 1 to stabilize the position of the punching mechanism 6. A cylinder 602 is fixedly connected to the top inner side of the punching base 601. The cylinder 602 drives the punching cutter 603 to move up and down. The bottom end of the cylinder 602 is fixedly connected to the punching cutter 603. The punching cutter 603 punches holes on the side of the packaging bag. The bottom of the punching cutter 603 fits against the top of the punching base 10 to complete the punching action. The top of the feeding mechanism 4 is provided with a pressing mechanism 3. The pressing mechanism 3 is used to absorb and filter the dust generated during the operation of the equipment, and at the same time apply stable pressure to the packaging bag to ensure the punching accuracy.

[0036] Specifically, the feeding mechanism 4 starts working under the drive component 5. The two servo motors 502 in the drive component 5 start, and the second transmission gear 503 at its output end drives the first transmission gear 501 to rotate through the track 504, thereby causing the feeding roller 401 and the discharge roller 403 to rotate synchronously. The feeding roller 401 conveys the packaging bag in. The limit ring 402 can prevent the packaging bag from shifting left and right during the conveying process. The pressing shaft 405 plays a certain downward pressing and guiding role on the packaging bag, ensuring that the packaging bag is smoothly conveyed to the punching position. When the packaging bag reaches the punching position, the punching mechanism 6 starts working. The cylinder 602 on the punching base 601 drives the punching cutter 603 to move downward, cooperating with the punching seat 10 to punch holes on the side of the packaging bag. The dust collection mechanism 2 continues to work to solve the dust problem. Dust generated by the high-speed friction between the drilling tool and the packaging material during drilling will permeate the workshop. The two suction pipes 201 of the dust collection mechanism 2 are located near the drilling area and can effectively collect dust. The dust enters the dust collection inlet pipe 202 through the suction pipes 201 and then reaches the filter cartridge 203. The filter component 207 inside the filter cartridge 203 filters the dust. The filtered clean air is discharged through the exhaust pipe 206. The vacuum cleaner 204 collects the dust inside the filter cartridge 203 to prevent dust accumulation from affecting the filtration effect. The dust collection mechanism 2 effectively collects and filters the dust generated during the drilling process, avoiding dust from permeating the working environment and harming the health of operators. It also prevents dust from entering the equipment and affecting the normal operation of other precision components, ensuring the stable operation of the equipment and the health and safety of operators.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The pressing mechanism 3 includes two fixed plates 301 for applying pressure to the packaging bag to assist in the punching operation. The rear sides of the two fixed plates 301 are respectively fixedly connected to the top of the left and right ends of the front side of the mounting plate 13. Slide rods 302 are slidably connected to the front and rear sides of the two fixed plates 301. The slide rods 302 allow the pressing shaft 305 to have vertical movement space. Springs 303 are slidably connected to the outer walls of the multiple slide rods 302. The springs 303 play the role of elastic buffering and pressure adjustment. The bottom of the multiple slide rods 302 are respectively fixedly connected to... The corresponding connecting shaft 304 is used to connect the slide rod 302 and the pressing shaft 305. The top ends of multiple springs 303 are respectively attached to the bottom front and rear sides of the corresponding fixing plate 301 to ensure that the upper end of the spring 303 is fixed. The bottom ends of multiple springs 303 are respectively attached to the top front and rear sides of the corresponding connecting shaft 304 to ensure that the lower end of the spring 303 is connected to the connecting shaft 304. The outer walls of the two connecting shafts 304 are rotatably connected to the pressing shaft 305. The pressing shaft 305 directly contacts the packaging bag and applies pressure.

[0038] Specifically, during equipment operation, two fixed plates 301 are fixed to the top front side of the mounting plate 13, providing stable support for the pressing mechanism 3. The slide rod 302 can slide freely on the front and rear sides of the fixed plate 301. This design allows the pressing shaft 305 to have a certain amount of vertical movement. The spring 303 is sleeved on the slide rod 302, with its top end fitting against the bottom of the fixed plate 301 and its bottom end fitting against the top of the connecting shaft 304. The spring 303 plays a key role in elastic buffering and pressure regulation. When the feeding mechanism 4 conveys the packaging bag to the punching position, the pressing shaft 305 contacts the packaging bag. Due to the elasticity of the spring 303, the pressing shaft 305... Shaft 305 can adapt to the unevenness of the packaging bag surface. Through the compression and extension of spring 303, it always maintains a uniform downward pressure on the packaging bag, ensuring that the packaging bag will not shift due to uneven local force during the punching process. The connecting shaft 304 enables the downward pressure shaft 305 to rotate. During the movement of the packaging bag, the downward pressure shaft 305 can roll smoothly, reducing the frictional resistance on the packaging bag and further ensuring that the packaging bag moves smoothly to the punching position. Moreover, it will not deviate from the predetermined position due to external force interference at the moment of punching, thereby effectively improving the punching accuracy and solving the problem of insufficient punching accuracy caused by unstable position of the packaging bag in the prior art.

[0039] Reference Figure 1 , Figure 2 and Figure 4 The inner wall of the operating table 7 is provided with a debris slide 8, which can guide the debris generated during the drilling process to slide down along the debris slide 8. A collection box 9 is fixedly connected to the bottom of the operating table 7. The collection box 9 is used to receive the debris that slides down from the debris slide 8, so as to realize the centralized collection of debris. A dust suction hood 11 is fixedly connected to the front side of each of the two dust suction branches 201. The dust suction hood 11 can effectively approach the drilling area to enhance the dust collection ability. Both dust suction hoods 11 adopt a funnel-shaped design, which can expand the dust suction range and improve the dust collection efficiency. The bottom of each of the multiple slide rods 302 is fixedly connected to a limit block 12. The limit block 12 plays the role of limiting the stroke of the slide rod 302 and preventing the slide rod 302 from coming out of the fixed plate 301. The bottom of the multiple limit blocks 12 respectively fits against the front and rear sides of the top of the corresponding fixed plate 301 to ensure that the limit block 12 and the fixed plate 301 are tightly fitted and stably perform the limiting function.

[0040] Specifically, the dust hood 11 is fixed to the front of the dust suction branch pipe 201. Its funnel-shaped design increases the dust collection range. The dust suction branch pipe 201 sucks away the dust and solves the problem of dust diffusion. The limiting block 12 at the bottom of the slide bar 302 fits against the top of the fixing plate 301 to prevent the slide bar 302 from slipping too much, ensuring the stability of the pressing mechanism 3 and avoiding the impact of drilling due to the instability of the mechanism.

[0041] Working principle: When the equipment is running, the feeding mechanism 4 starts working under the drive component 5. The two servo motors 502 in the drive component 5 start, and the second transmission gear 503 at its output end drives the first transmission gear 501 to rotate through the track 504, thereby causing the feeding roller 401 and the discharge roller 403 to rotate synchronously. The feeding roller 401 conveys the packaging bag in. The limit ring 402 can prevent the packaging bag from shifting left and right during the conveying process. The pressing shaft 405 plays a certain role in pressing down and guiding the packaging bag, ensuring that the packaging bag is smoothly conveyed to the punching position. When the packaging bag reaches the punching position, the punching mechanism 6 starts working. The cylinder 602 on the punching base 601 drives the punching cutter 603 to move downward, cooperating with the punching seat 10 to punch holes on the side of the packaging bag. The dust collection mechanism 2 continues to work to solve the dust problem. The problem is that dust generated by the high-speed friction between the cutting tool and the packaging bag material during drilling will permeate the workshop. The two suction pipes 201 of the dust collection mechanism 2 are located near the drilling area and can effectively collect dust. The dust enters the dust collection inlet pipe 202 through the suction pipes 201 and then reaches the filter cartridge 203. The filter component 207 inside the filter cartridge 203 filters the dust. The filtered clean air is discharged through the exhaust pipe 206. The vacuum cleaner 204 collects the dust inside the filter cartridge 203 to prevent dust accumulation from affecting the filtration effect. The dust collection mechanism 2 effectively collects and filters the dust generated during the drilling process, avoiding dust from permeating the working environment and harming the health of the operators. It also prevents dust from entering the equipment and affecting the normal operation of other precision components, ensuring the stable operation of the equipment and the health and safety of the operators.

[0042] Furthermore, during equipment operation, two fixed plates 301 are fixed to the top front side of the mounting plate 13, providing stable support for the pressing mechanism 3. The slide rod 302 can slide freely on the front and rear sides of the fixed plate 301. This design allows the pressing shaft 305 to have a certain amount of vertical movement. The spring 303 is sleeved on the slide rod 302, with its top end fitting against the bottom of the fixed plate 301 and its bottom end fitting against the top of the connecting shaft 304. The spring 303 plays a crucial role in elastic buffering and pressure regulation. When the feeding mechanism 4 conveys the packaging bag to the punching position, the pressing shaft 305 contacts the packaging bag. Due to the elasticity of the spring 303, the pressing shaft... 305 can adapt to the unevenness of the packaging bag surface. Through the compression and extension of the spring 303, it always maintains a uniform downward pressure on the packaging bag, ensuring that the packaging bag will not shift due to uneven local force during the punching process. The connecting shaft 304 enables the downward pressure shaft 305 to rotate. During the movement of the packaging bag, the downward pressure shaft 305 can roll smoothly, reducing the frictional resistance on the packaging bag and further ensuring that the packaging bag moves smoothly to the punching position. Moreover, it will not deviate from the predetermined position due to external force interference at the moment of punching, thereby effectively improving the punching accuracy and solving the problem of insufficient punching accuracy caused by the unstable position of the packaging bag in the prior art.
