Abstract
Description
Technical Field
[0001] This utility model relates to a non-woven packaging bag production device, belonging to the field of packaging equipment. Background Technology
[0002] Most packaging bags currently used are made of plastic. Plastic bags are filled directly during the molding process and then heat-sealed, which is highly efficient.
[0003] However, flour needs to be stacked during logistics and transportation, and the strength of plastic packaging is insufficient. Using woven bags can lead to leakage, while using fixed containers or cloth bags is costly.
[0004] Considering both structural strength and price, non-woven fabric packaging bags are becoming increasingly popular for flour packaging. Non-woven fabrics possess the foldable properties of plastics, are easy to print on, and have a structural strength suitable for stacking and conveying. However, the production of non-woven packaging bags is still in a phased stage, lacking equipment that integrates printing, folding, and sewing into a single production line. Summary of the Invention
[0005] To address the above problems, this invention provides a nonwoven packaging bag production device that solves the problem of integrated production line production of nonwoven packaging.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] This utility model relates to a non-woven packaging bag production device, comprising a feeding mechanism, a folding mechanism, a printing mechanism, a buffer feeding rack, a bag folding machine, and a sewing mechanism.
[0008] The feeding mechanism includes a feeding frame, an inclined cantilever, a lifting arm, a roller positioning mechanism, a hydraulic cylinder, and a feeding drive. The front end of the feeding frame is provided with a cantilever, and the feeding drive is provided on the inclined upper part of the cantilever. One end of the lifting arm is hinged to the feeding frame at the lower part of the lifting arm. The bottom of the hydraulic cylinder is hinged to the feeding frame. The front end of the piston rod of the hydraulic cylinder is the roller positioning mechanism. A non-woven fabric roll is placed on the roller positioning mechanism. The end of the non-woven fabric roll is connected to the feeding drive. The feeding drive on the non-woven fabric roll and the feeding drive at the end of the cantilever are poweredly connected.
[0009] The folding mechanism is located at the rear end of the feeding mechanism, and the printing mechanism is located at the rear end of the folding mechanism. The printing mechanism is connected to the bag folding machine through a buffer feeding frame. A conveyor is located at the rear end of the bag folding machine, and the sewing mechanism is located on the conveyor.
[0010] According to the nonwoven packaging bag production device, the folding mechanism includes multiple sets of steering rollers, lower pressure rollers, folding plate, folding guide plate, folding pressing block, and folding frame. The front end of the folding frame is provided with an infeed steering roller, the outlet end is provided with an outlet steering roller, the middle is provided with a folding plate, and the two sides of the folding plate are provided with folding pressing blocks. The folding guide plate is provided in front of the pressing block and is located on the edge side of the nonwoven fabric. The folding pressing block is triangular, with one side inclined from the infeed side to the outlet side towards the middle of the folding plate. The folding plate is parallel to the folding pressing block. The edge of the nonwoven fabric raw material is folded inward from the folding guide plate and then completely folded towards the middle of the folding pressing block.
[0011] According to the nonwoven packaging bag production device, the buffer feeding frame includes a buffer feeding frame, a fixed buffer roller and a movable buffer roller. The fixed buffer roller is fixed on the buffer feeding frame, and the movable buffer roller is set at the lower part of two sets of adjacent fixed buffer rollers through an elastic mechanism. The nonwoven fabric turns downward from the fixed buffer roller, turns upward through the movable buffer roller, and then turns again at the position of another fixed buffer roller.

The steering rollers are respectively set at the front and rear ends of the bag folding frame. A prime number of stacking frames are set in the middle of the bag folding frame. The power rollers are located at the rear end of the stacking frames. The stacking frames are triangular in shape, surrounded by an isosceles triangular plane and steering plates on both sides. One side of the two steering plates is fixedly connected to the two isosceles sides of the triangular plane. The other side of the two steering plates is parallel and the distance between them is maintained at a gap. The triangular pressure plate is parallel to the triangular plane and has the same shape as the triangular plane. The connecting side of the triangular pressure plate and the steering plate is parallel and spaced apart. The nonwoven fabric enters between the triangular pressure plate and the triangular plane through the opening of the triangular plane and exits between the two steering plates and enters between the power rollers.

[0020] The specific structure of this utility model will be further described below:
[0021] This utility model relates to a non-woven packaging bag production device, comprising a feeding mechanism 1, a folding mechanism 2, a printing mechanism 3, a buffer feeding frame 4, a bag folding machine 5, and a sewing mechanism 6. The folding mechanism 2 is located at the rear end of the feeding mechanism 1, and the printing mechanism 3 is located at the rear end of the folding mechanism 2. The printing mechanism 3 is connected to the bag folding machine 5 via the buffer feeding frame 4. A conveyor is located at the rear end of the bag folding machine, and the sewing mechanism 6 is mounted on the conveyor.
[0022] In this device, the feeding mechanism 1 holds the roll of nonwoven fabric raw material, which rotates and releases the nonwoven fabric during operation; the folding structure folds the edges of the nonwoven fabric 3-10cm to strengthen the opening of the nonwoven packaging bag; the printing mechanism prints the product information onto the nonwoven fabric; the buffer feeding mechanism connects the bag folding machine and the printing machine, allowing the printed nonwoven fabric to dry quickly; the bag folding machine folds wide nonwoven fabric raw materials to form a bag body; and the sewing mechanism sews the edges of the folded nonwoven fabric to form a complete packaging cavity. The nonwoven fabric prepared by this device can be fitted with a slitting mechanism after the bag folding machine 5 to separate the nonwoven packaging bag before the sewing edges.
[0023] Specifically, the feeding mechanism 1 in this device includes a feeding frame 2, an inclined cantilever 12, a lifting arm 13, a roller positioning mechanism 14, a hydraulic cylinder 15, and a feeding drive 16. The cantilever 12 is located at the front end of the feeding frame 2, and the feeding drive 16 is located at the inclined upper part of the cantilever 12. One end of the lifting arm 13 is hinged to the feeding frame 2 at its lower position. The bottom of the hydraulic cylinder is hinged to the feeding frame 2. The roller positioning mechanism 14 is located at the front end of the lifting arm 13, and the piston rod of the hydraulic cylinder is hinged to the lower front end of the lifting arm 13. A non-woven fabric roll 17 is placed on the roller positioning mechanism 14, and the end of the non-woven fabric roll 17 is connected to the feeding drive 16. The feeding drive 16 on the non-woven fabric roll 17 and the feeding drive 16 at the end of the cantilever 12 are dynamically connected.
[0024] During feeding, the lifting arm is first lowered to a low position by a hydraulic cylinder. The nonwoven fabric roll is then placed on the roller positioning mechanism 14 by a lifting structure. The hydraulic cylinder then raises the cantilever to a high position. The driven mechanism at the front end of the lifting arm 13 contacts the feeding drive at the end of the cantilever, which drives the nonwoven fabric roll to release the nonwoven fabric.
[0025] Specifically, the folding mechanism 2 includes multiple sets of steering rollers 21, lower pressure rollers 22, folding plate 23, folding guide plate 24, folding pressure block 25, and folding frame 26. The front end of the folding frame 26 is provided with a material inlet steering roller 21, the outlet end is provided with an outlet steering roller 21, the middle is provided with a folding plate 23, and the two sides of the folding plate 23 are provided with folding pressure blocks 25. The folding guide plate 24 is provided in front of the pressure block and is located on the edge side of the non-woven fabric. The folding pressure block 25 is triangular, with one side inclined from the material inlet side to the material outlet side towards the middle of the folding plate 23. The folding plate 23 is parallel to the folding pressure block 25. The edge of the non-woven fabric raw material is folded inward from the folding guide plate 24 and completely folded towards the middle of the folding pressure block 25. The nonwoven fabric raw material is turned downward at the turning roller, and the lower pressure roller enters the position above the folding plate. The folding guide plate and folding pressure block 25 at the edge of the nonwoven fabric raw material together fold the edge of the nonwoven fabric inward and then flatten it in the subsequent roller pressing equipment.
[0026] The folded nonwoven fabric enters the printing press for printing. After printing, it is buffered and fed into the buffer feeder 4, where the printing dye is simultaneously air-dried. The buffer feeder 4 includes fixed buffer rollers and movable buffer rollers. The fixed buffer rollers are fixed on the buffer feeder 4, and the movable buffer rollers are positioned below two adjacent sets of fixed buffer rollers via an elastic mechanism. The nonwoven fabric turns downwards from the fixed buffer rollers, then upwards via the movable buffer rollers, and then turns again at the position of another fixed buffer roller. The elastic mechanism controls the continuous output from the printing press to the bag folding machine, controlling the feeding speed of the bag folding machine and extending the conveying time of the printed nonwoven fabric.
[0027] The bag folding machine in this device includes multiple steering rollers 21, a pair of power rollers, a stacking frame, and a bag folding frame. The steering rollers 21 are respectively installed at the front and rear ends of the bag folding frame. A prime number of stacking frames are installed in the middle of the bag folding frame. The power rollers are located at the rear end of the stacking frames. The stacking frames are triangular in shape, surrounded by an isosceles triangular plane and steering plates on both sides. One side of the two steering plates is fixedly connected to the two isosceles sides of the triangular plane. The other side of the two steering plates is parallel and the distance between them is maintained at a gap. The triangular pressure plate is parallel to the triangular plane and has the same shape as the triangular plane. The connecting side of the triangular pressure plate and the steering plate is parallel and spaced apart. The nonwoven fabric enters between the triangular pressure plate and the triangular plane through the opening of the triangular plane and exits between the two steering plates into the space between the power rollers.
[0028] The non-woven fabric enters the gap between the triangular plane and the triangular pressure plate in the folding frame, where the edge of the non-woven fabric turns at the position of the turning plate and completes symmetry at the apex position of the triangular plane and the triangular pressure plate, passing through the gap between the two turning plates.
[0029] After being folded in a bag-folding machine, the non-woven fabric is heat-sealed and cut into individual non-woven packaging bags. The folded edges are simply heat-sealed together, and then the bags enter the conveyor line where the edges are sewn together by a sewing mechanism to produce complete non-woven packaging bags.
[0030] This device integrates the folding, printing, folding, and sewing of non-woven packaging bags into a single production line, improving production efficiency. Its compact structure saves space compared to individual equipment setups.
