Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven bag making equipment, and in particular to a computer-controlled nonwoven bag making machine with stable material feeding. Background Technology

[0002] With the continuous advancement of environmental protection policies and the increasing environmental awareness of the public, non-woven bags, as reusable and biodegradable environmentally friendly packaging products, are increasingly widely used in packaging, retail, and advertising. Computerized non-woven bag making machines, as key equipment in the production of these environmentally friendly bags, directly affect the product's forming quality and production efficiency due to their level of automation and intelligence. During the bag-making process, the stable feeding of the fabric is particularly crucial, as it relates to the coordinated operation between various processes and the dimensional accuracy of the finished bags.

[0003] Existing computerized nonwoven bag making machines typically include an unwinding mechanism, a feeding roller assembly, a heat sealing device, a cutting unit, and a control system. The feeding system usually employs several sets of fixed rollers driven by a motor, continuously conveying the fabric from the roll to the processing unit through friction. To ensure synchronous feeding, the system sets a constant feeding speed, with the controller precisely adjusting the feeding rhythm. During machine operation, the feeding rollers guide the fabric and transmit tension, working in conjunction with subsequent heat sealing and bag cutting processes to achieve continuous automated production.

[0004] However, existing equipment generally suffers from insufficient fabric tension control during actual operation. Due to the lack of automatic tension adjustment in traditional structures, the outer diameter of the roll gradually decreases with continuous use, leading to weakened feeding tension and fabric slack or slippage. This situation causes poor feeding and fabric deviation, affecting the accuracy of subsequent edge sealing and cutting. Furthermore, it increases equipment failure rate, reduces production efficiency and product quality, and makes it difficult to meet the requirements for continuous and highly stable production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a computer-controlled nonwoven bag making machine with stable material feeding, aiming to improve the existing structure which lacks a tensioning structure, causing the fabric to loosen as the roll diameter gradually decreases during the conveying process, resulting in problems such as poor fabric feeding or slippage during material pulling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a computer-controlled nonwoven bag making machine with stable feeding capability, comprising a base plate, a connecting plate fixedly connected to the upper surface of the base plate, and an adjustment component provided on one side of the inner wall of the connecting plate;

[0007] The adjusting assembly includes a fixed block, the outer wall of which is disposed on one side of the inner wall of the connecting plate. A hydraulic cylinder is fixedly connected to one side of the outer wall of the connecting plate. A sliding roller is fixedly connected to the output end of the hydraulic cylinder. A sliding sleeve is slidably connected to the outer wall of the sliding roller. A sliding groove is opened inside the sliding sleeve. Four sets of connecting rods are rotatably connected to the inner wall of the sliding roller. The outer walls of the four sets of connecting rods are rotatably connected to the inner wall of the fixed block. A fixed rod is fixedly connected to the outer wall of the fixed block. A fixed plate is slidably connected to the outer wall of the sliding roller.

[0008] Furthermore, a column is fixedly connected to the outer wall of the base plate, a roller is rotatably connected to the inner wall of the column, a conveyor body is provided on one side of the outer wall of the column, a base is fixedly connected to the lower surface of the conveyor body, a rack and a rack are slidably connected to the inner wall of the base, a lead screw is threaded to the inner wall of the conveyor body, a connecting block is provided at one end of the lead screw, a gear is rotatably connected to the inner wall of the connecting block, racks and racks mesh on both sides of the outer wall of the gear, a guard is fixedly connected to the upper surface of rack, and a roller is rotatably connected to the inner wall of guard.

[0009] Furthermore, a hot press forming machine is fixedly connected to the outer wall of the conveyor body, and a cutting machine body is provided on one side of the outer wall of the hot press forming machine.

[0010] Furthermore, a second column is fixedly connected to the upper surface of the cutting machine body, and a third roller is fixedly connected to the inner wall of the second column.

[0011] Furthermore, a second protective frame is fixedly connected to the upper surface of the cutting machine body, and a cutting tool is fixedly connected to the inner wall of the second protective frame.

[0012] Furthermore, the fixing plate is fitted with the sliding sleeve, and the outer wall of the connecting rod is slidably connected to the inner wall of the sliding sleeve.

[0013] Furthermore, one end of the sliding sleeve is fixedly connected to the outer wall of another connecting plate, and the fixing block is in contact with the sliding sleeve.

[0014] Furthermore, the gear is located inside the conveyor body, and the outer wall of the fixing rod is slidably connected to the inner wall of the fixing plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by setting a connecting plate and its internal adjustment components on the base plate, the distance between the sliding roller and the fixed plate is changed by using a hydraulic cylinder. With the help of the sliding sleeve and sliding groove structure, as well as four sets of connecting rods, the sliding roller is guided and limited. This allows the spacing between the feeding rollers to be dynamically adjusted when the fabric roll diameter changes, automatically compensating for tension fluctuations, thereby always keeping the fabric in a taut state. This structure effectively avoids the problems of slippage, deviation or wrinkling of the fabric during feeding caused by the looseness or uneven tension of the fabric in traditional bag making machines. It improves the continuity, stability and bag making accuracy of the feeding process, and ensures the consistency and reliability of the finished bag forming.

[0017] 2. In this utility model, the fabric pressing distance between the upper and lower rollers is controlled by setting a rack-gear-screw linkage mechanism. By adjusting the roller spacing, the fabric tension can be flexibly adjusted to adapt to non-woven fabric materials of different thicknesses and hardnesses. After the upper and lower rollers form a fabric pressing structure, the feeding is more stable, which can avoid tension imbalance caused by uneven fabric thickness and effectively prevent fabric wrinkling, excessive stretching or slippage. With the coordinated work of the conveying mechanism, hot pressing forming machine and cutting unit, this invention not only improves the feeding accuracy, but also ensures the synchronization of subsequent hot pressing and cutting processes, thus improving the overall efficiency and product yield of non-woven bag making.

A second column 14 is fixedly connected to the upper surface of the cutting machine body 12. A third roller 15 is fixedly connected to the inner wall of the second column 14. A second guard frame 13 is fixedly connected to the upper surface of the cutting machine body 12. A cutting blade 16 is fixedly connected to the inner wall of the second guard frame 13. The cutting blade 16 is used to cut the formed fabric into a predetermined shape and structure.

The outer wall of the connecting rod 19 is slidably connected to the inner wall of the sliding sleeve 17. One end of the sliding sleeve 17 is fixedly connected to the outer wall of another connecting plate 3. The fixed block 20 is attached to the sliding sleeve 17. The gear 26 is set inside the conveyor body 7. The conveyor body 7 is used for horizontal conveying and transporting of the fabric. It provides a continuous conveying path between processes such as feeding, hot pressing, and forming. At the same time, it is equipped with adjustment mechanisms such as gear 26 and lead screw 23. The outer wall of the fixed rod 21 is slidably connected to the inner wall of the fixed plate 4.

[0029] Working principle: When a computer-controlled nonwoven bag making machine with stable feeding is required, the tension control of the nonwoven fabric feeding process is achieved through the connecting plate 3 set on the base plate 1 and the internal adjustment components. The fixing block 20 is set on the inner wall of the connecting plate 3 to support four sets of connecting rods 19. One end of the connecting rod 19 is rotatably connected to the inner wall of the fixing block 20, and the other end is rotatably connected to the inner wall of the sliding roller 18. The outer wall of the sliding roller 18 is fitted with a sliding sleeve 17, which has a sliding groove 22 inside, so that the connecting rod 19 can move within the range of the inner wall of the sliding sleeve 17. Limiting the sliding is achieved, thereby realizing the dynamic clamping adjustment of the roller body. The hydraulic cylinder 2 is fixed on the outer wall of the connecting plate 3. Through its output end, it pushes the sliding roller 18 to slide along the direction of the fixed rod 21, thereby adjusting the distance between the sliding roller 18 and the fixed plate 4. When the diameter of the fabric roll gradually decreases, the inner diameter of the feed roller is adjusted by hydraulic drive, pushing the sliding roller 18 closer to the fabric direction to keep the fabric continuously taut. This structure effectively avoids problems such as slippage and deviation caused by fabric slack, and improves the stability and continuity of the feeding process.

[0030] Furthermore, during the feeding process, the fabric is continuously transported through the conveyor body 7. The base 8 below it contains rack 25 and rack 27, which mesh with the two sides of gear 26 within the conveyor body 7. Gear 26 is driven by lead screw 23 to rotate on the two racks. One end of lead screw 23 is connected to block 24, thus enabling coordinated adjustment of the rack positions. A guard frame 9 is fixedly connected to the upper part of rack 27. Roller 10 is installed inside guard frame 9, forming an upper and lower pressure roller structure through cooperation with roller 6 inside column 5. Adjusting the positions of rack 25 and rack 27 controls the distance between roller 6 and roller 10. A smaller roller gap increases fabric tension, and a larger gap decreases tension. This adjustment structure allows for flexible tension adjustment based on fabric thickness and characteristics, preventing fabric loosening, wrinkling, or excessive stretching, thus improving feeding accuracy and the final bag-making product's forming quality and consistency.
