Description

Technical Field

[0001] This utility model relates to the field of packaging bag making technology, specifically a three-dimensional folding bag making machine with a punching function. Background Technology

[0002] Packaging bags are bags used to package various goods, facilitating transportation and storage during production and distribution. The commercial nature of packaging itself is becoming increasingly prominent; it has become a special product no longer dependent on commodity production, but a widely used product indispensable to all commodities.

[0003] 3D folded edge bags are commonly used by various takeout vendors and milk tea shops. They are usually non-woven fabric packaging bags. Some 3D folded edge bags require perforation for functions such as heat dissipation or positioning. Existing bag making machines typically use a hollow perforating shaft for perforation. The lower end of the perforating shaft has a shark tooth-shaped ring for cutting the non-woven fabric. The non-woven fabric is fed forward intermittently by a feeding device. The perforating device intermittently moves up and down in conjunction with the feeding device to achieve perforation. The perforated non-woven fabric is then fed into a handle welding device and an inner folding device. The controller of the inner folding machine regulates the inner folding device to finally obtain the 3D folded edge bag.

[0004] However, existing punching devices have the following problems: fabric fragments generated during punching may get stuck inside the punching shaft or on the shark teeth, which may cause a lot of burrs on the edge of the round hole, requiring the fabric fragments to be cleaned. The feeding device and the punching device need to be repeatedly adjusted, and improper coordination may cause the punching position to be unstable and the relative distance of the round holes to be inconsistent. Therefore, we propose a three-dimensional folding bag making machine with punching function. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This three-dimensional folding bag making machine with perforation function has the following advantages:

[0016] 1. When the non-woven fabric that has completed the external folding and welding passes through the perforation groove, the second motor starts, driving the rotating wheel to rotate one revolution. Through the connecting rod, it drives the perforation seat to move up and down once, realizing the perforation. When the lower end of the perforation seat passes through the non-woven fabric, the perforation seat is a hollow perforation seat. The external air pump blows air through the air blowing hole, blowing out the non-woven fabric fragments located inside the perforation seat. The non-woven fabric fragments are blown to the lower end of the non-woven fabric, avoiding contact between the non-woven fabric fragments and the non-woven fabric, reducing the generation of perforation burrs, and improving the perforation quality.

[0017] 2. When the round hole of the nonwoven fabric passes through the photoelectric switch, the photoelectric switch sends a position signal to the controller of the inward folding machine. The controller of the inward folding machine controls the second motor to start and punch holes. The relative distance between the two holes is the relative distance between the photoelectric switch and the punching seat, which realizes the correction of the punching position. After the vertical bag is processed, the round hole positions are the same. Attached Figure Description

When the lower end of the punching seat 65 passes through the non-woven fabric, the external air pump blows air through the air blowing hole 64 to blow out the non-woven fabric fragments located inside the punching seat 65. The non-woven fabric fragments are blown to the lower end of the non-woven fabric. When the round hole of the non-woven fabric passes through the photoelectric switch 62, the photoelectric switch 62 sends a position signal to the controller of the inner folding machine.

The base 3 A magnetic powder brake 39 is fixedly connected to the right side of the 8. The right side of the cutting shaft 37 is inserted into the brake hole of the magnetic powder brake 39. The input end of the magnetic powder brake 39 is electrically connected to the output end of the controller of the inner folding machine. It also includes a roll welding worktable 2, which is placed between the support base 1 and the base 38. The upper end of the roll welding worktable 2 is equipped with ultrasonic roll welding machines 4 symmetrically distributed on the left and right. The input ends of the ultrasonic roll welding machines 4 are electrically connected to the output end of the controller of the inner folding machine. The non-woven fabric roll is sleeved on the outside of the cutting shaft 37, and the non-woven fabric is manually pulled out and passed through the guide shaft 36 and the lower shaft 37 in sequence.

When passing between the lower outer folding shaft 33 and the upper outer folding shaft 34, the edge is manually folded, and the folding distance is determined by the positioning ring 7. The distance between the two limiting rings 35 of the third guide shaft 36 is the same as the width of the nonwoven fabric, and the distance between the two limiting rings 35 of the first guide shaft 31 and the second guide shaft 32 is the same as the distance between the two positioning rings 7, so as to avoid the nonwoven fabric from deviating.

[0026] The working principle of the three-dimensional folding bag making machine with perforation function provided by this utility model is as follows: A handle welding device and an inward folding device are set at the rear end of the three-dimensional folding bag making machine with perforation function. These devices form a production line for three-dimensional folding bags. Each device is controlled by the controller of the inward folding machine. The non-woven fabric roll is placed outside the cutting shaft 37. The non-woven fabric is manually pulled out and passes sequentially between guide shaft three 36, the lower outer folding shaft 33 and the upper outer folding shaft 34, guide shaft two 32, guide shaft one 31, the welding roller of the ultrasonic welding machine 4, the inside of the perforation groove 63, and between the two tension shafts 53. The magnetic powder brake 39 keeps the non-woven fabric taut at all times. When passing between the lower outer folding shaft 33 and the upper outer folding shaft 34, the edge is manually folded. The folding distance is determined by the positioning ring 7. The distance between the two limiting rings 35 of guide shaft three 36 is the same as the width of the non-woven fabric. The distance between the two limiting rings 35 of guide shaft one 31 and guide shaft two 32 is the same as the distance between the two positioning rings 7, avoiding… When the non-woven fabric deviates from its intended path, the folded non-woven fabric is pressed and folded by guide shaft 1 31 and guide shaft 2 32. The welding rollers of the ultrasonic welding machine 4 perform ultrasonic welding to fix the folded edge. When it passes through the punching groove 63, motor 2 69 starts, driving the rotating wheel 68 to rotate one revolution. This rotation, via connecting rod 67, drives the punching seat 65 to move up and down once, thus punching a hole. When the lower end of the punching seat 65 passes through the non-woven fabric, an external air pump blows air through the air blowing hole 64, blowing out the non-woven fabric fragments located inside the punching seat 65. Nonwoven fabric fragments are blown to the lower end of the nonwoven fabric. When the round hole of the nonwoven fabric passes through the photoelectric switch 62, the photoelectric switch 62 sends a position signal to the controller of the inner folding machine. The controller of the inner folding machine controls the second motor 69 to start punching and realize the correction of the punching position. The output shaft of the first motor 51 rotates, driving the upper tension shaft 53 and gear 54 to rotate. Through the meshing of the two gears 54, the relative rotation of the two tension shafts 53 is realized, pulling the nonwoven fabric to the rear side to realize the feeding of the nonwoven fabric.

[0027] It is worth noting that, in the above embodiments, the motor 51 can be a CH200 geared motor, the photoelectric switch 62 can be an E3FA-TP11-D photoelectric switch, the motor 69 can be an HSV-24-350 servo motor, the magnetic powder brake 39 can be a ZA-A magnetic powder brake, and the ultrasonic welding machine 4 can be a CX-1500P ultrasonic welding machine. The controller of the inner folding machine controls the operation of the motor 51, the photoelectric switch 62, the motor 69, the magnetic powder brake 39, and the ultrasonic welding machine 4 using methods commonly used in the prior art.
