Description

Technical Field

[0001] The utility model relates to the technical field of woven bag processing, in particular to a hot cutting and sewing component for woven bags. Background Technique

[0002] With the development of society, people's work and life have become much more convenient. In this stage of development, plastics are more widely used, and plastic woven bags are one of them. Most people engaged in work, farming, cargo transportation, and going to the market use plastic woven products. Plastic woven products can be found everywhere in stores and warehouses. The padding material of chemical fiber carpets has also been replaced by plastic woven fabrics. Woven bags are indispensable in supermarket shopping bags, freight woven bags for logistics transportation, logistics woven bags, flood fighting and disaster relief, etc. And wire drawing is an important link in the process of plastic woven bags, which is very important for the production of woven bags.

[0003] The patent with the publication number CN210257449U discloses a hot cutting machine for woven bag forming, including a base. An electric cabinet is arranged on the upper surface of the base. A machine tool platform is arranged at the top of the electric cabinet. A base is bolted and fixed at the center of the upper surface of the machine tool platform. Hydraulic lifting columns are bolted and fixed at the four corners of the outer surface of the top of the base. A support platform is welded at the center of the upper surface of the base. The top ends of the four hydraulic lifting columns are fixedly connected to the same top plate. A hot cutting mechanism is arranged at the bottom end of the top plate. Installation grooves are symmetrically arranged on the two side walls of the base along the radial direction. Bag feeding mechanisms are arranged on the two sides of the base along the transverse direction. However, when the existing woven bag production and weaving device for heat-resistant woven bags is actually used, there are still many drawbacks. For example, after the woven bag is moved to the corresponding position, it needs to be positioned and fixed. But usually in use, only by placing blocks on both sides of the woven bag to position the woven bag, it is very easy for the device to shift during the working process, affecting the cutting work. Therefore, it is very necessary to design a hot cutting and sewing component for woven bags that is convenient for fixing the position of the woven bag. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hot cutting and sewing component for woven bags to solve the problems put forward in the above background technique.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a woven bag hot cutting and seaming assembly, comprising a main body, the front end of the main body is fixedly connected to a guide rod, the upper surface of the main body is provided with a cutting assembly, the rear end of the main body is provided with a collecting assembly, and moving assemblies are provided on both sides of the main body, a second bracket is fixedly connected to the middle of the upper surface of the main body, a guide roller is rotatably connected to the inner side of the second bracket, a guide rod is provided below the guide roller, and the guide rod is rotatably connected to the second bracket, both sides of the second bracket are fixedly connected to a fixed block, a guide shaft is fixedly connected between the two fixed blocks, the upper surface of the guide shaft is rotatably connected to a guide wheel, and the rear end of the main body is fixed with a connecting rod, the cutting assembly comprises a first bracket, the first bracket is fixedly connected to the rear end of the upper surface of the main body, the upper surface of the first bracket is fixedly connected to two cylinders, the bottom ends of the two cylinders are provided with an output rod, the output end of the output rod is fixedly connected to a cutting knife, and the front and rear sides of the cutting knife are respectively fixedly connected to two connecting buckles, and each of the connecting buckles is hinged to a hinged rod at one end away from the cutting knife, and the hinged rod is hinged at one end away from the cutting knife There is an ear plate, and a pressing plate is fixedly connected to the lower surface of the ear plate. A vertical groove is opened on the outer surface of the first bracket, and the vertical groove runs through one side of the first bracket to the other side, and the vertical groove is slidably connected to the support rod. An elastic spring is fixedly connected to the middle position of the upper surface of the pressing plate. The woven bag is guided from the top of the guide rod to between the guide roller and the guide rod. Since the guide roller and the guide rod are rotatably connected to the second bracket, the guiding direction is assisted again when passing between the guide roller and the guide rod. Then the woven bag falls above the guide shaft rod, and the probability of the woven bag offset is reduced under the action of the guide wheel. When the woven bag moves to the front end of the main body, the cylinder starts to operate, causing the cutting knife to move downward. As the cutting knife moves downward, the pressing plate moves downward with the cutting knife. Under the joint action of the hinged rod, ear plate, and elastic spring, the cutting knife moves downward so that the pressing plates on both sides contact the woven bag and move away from each other. Then the pressing plate drives the connected hinged rod through the ear plate to deflect around the connection point of the cutting knife, so that the pressing plate can firmly press the woven bag against the upper surface of the main body while moving to both sides. Then the cutting knife falls until it contacts the woven bag, and the woven bag will be cut at this time.

[0006] The moving component includes a transmission gear, the outer surface of the rear side of the transmission gear is meshed with a first rack plate, the outer surface of the bottom side of the transmission gear is meshed with a second gear plate, guiding blocks are fixed on both sides of the front end of the main body, a limiting block is fixedly connected to the top end of the front side of the guiding block, a pressing rod is slidably penetrated through the limiting block, a return spring is arranged inside the limiting block, and both ends of the return spring are fixedly connected to the limiting block and the pressing rod respectively. The collecting component includes a collecting box, a horizontal groove is formed in the middle of the box body and extends from one side of the box body to the other side, a guiding plate is fixedly connected above the inner wall of the box body, the collecting box is slidably connected in the middle of the box body, two positioning blocks are fixedly connected to the top surface of the box body, one end of the elastic spring away from the pressing plate is fixedly connected to the cutting knife. The first rack plate is meshed with the transmission gear, and the second gear plate is meshed with the transmission gear. Since the support rod is fixedly connected to the cutting knife and the support rod is fixedly connected to the first rack plate, when the cutting knife drops, the first rack plate will move downward synchronously with the cutting knife. When the support rod causes the first rack plate to move downward, the transmission gear rotates clockwise, and at this time, it will drive the second gear plate to move forward. Therefore, when the first rack plate drops, the box body will move forward. When the pressing rod contacts the guiding block, there is a gap between the pressing rod and the guiding block, and the woven bag passes through between the pressing rod and the guiding block. After cutting is completed, the box body moves forward, causing the pressing rod to disengage from the guiding block. The pressing rod and the guiding block are reset under the action of the return spring and approach the positioning block to clamp the cut woven bag. When the woven bag disengages from the main body, the pressing rod will guide the woven bag to fall into the collecting box through the guiding plate. When the number of woven bags in the collecting box reaches a certain amount, the handle can be pulled to take out the woven bags in the collecting box, and the cut woven bags are separated from the uncut woven bags by moving through the collecting box.

Subsequently, the pressing plate drives the connected hinge rod to deflect around the connection point with the cutting knife through the ear plate, so that while the pressing plate moves to both sides, the woven bag can be firmly pressed on the upper surface of the main body. Then the cutting knife drops to contact the woven bag, and at this time, the woven bag will be cut. By moving the two pressing plates away from each other, the cut part of the woven bag is tightened, avoiding the deviation or wrinkle of the woven bag from affecting the cutting effect.

[0009] The utility model is provided with a fixed block, a guide wheel, a moving component, a first rack plate, a transmission gear, a second gear plate, a pressing rod, a guiding block, a limiting block, a guiding roller, a collecting component and a collecting box, so that the cut woven bag is separated from the uncut woven bag through the movement of the collecting box, and the cut woven bag falls to a designated position, playing a role in storage and stacking.

[0020] Working principle: The woven bag is guided above the guiding rod 3 to between the guiding roller 8 and the guiding rod 10. Since the guiding roller 8 and the guiding rod 10 are rotatably connected to the second bracket 12, the direction is assisted and guided again when passing between the guiding roller 8 and the guiding rod 10. Subsequently, the woven bag falls above the guiding shaft rod 13, and the probability of the woven bag shifting is reduced under the action of the guiding wheel 6. When the woven bag moves to the front end of the main body 1, the air cylinder 406 starts to operate, causing the cutting knife 402 to move downward. While the cutting knife 402 moves downward, the pressing plate 405 follows the cutting knife 402 and moves downward together. Under the combined action of the hinge rod 403, the ear plate 404, and the elastic spring 408, when the cutting knife 402 moves downward, the two side pressing plates 405 contact the woven bag and move away from each other. Subsequently, the pressing plate 405 drives the connected hinge rod 403 to deflect around the connection point with the cutting knife 402 through the ear plate 404, enabling the pressing plate 405 to firmly press the woven bag on the upper surface of the main body 1 while moving to both sides. Subsequently, the cutting knife 402 drops to contact the woven bag, and at this time, the woven bag will be cut. By moving the two side pressing plates 405 away from each other, the cutting part of the woven bag is tightened, preventing the woven bag from shifting or wrinkling and affecting the cutting effect. Since the support rod 409 is fixedly connected to the cutting knife 402 and the support rod 409 is fixedly connected to the first rack plate 701, when the cutting knife 402 drops, the first rack plate 701 will move downward synchronously with the cutting knife 402. When the support rod 409 moves the first rack plate 701 downward, the transmission gear 702 rotates clockwise, and at this time, it will drive the second gear plate 703 to move forward. Therefore, when the first rack plate 701 drops, the box body 2 will move forward. When the pressing rod 704 contacts the guiding block 705, there is a gap between the pressing rod 704 and the guiding block 705, and the woven bag passes through between the pressing rod 704 and the guiding block 705. When the cutting is completed, the box body 2 moves forward, causing the pressing rod 704 to disengage from the guiding block 705. The pressing rod 704 and the guiding block 705 are reset and approach the positioning block under the action of the reset spring to clamp the cut woven bag. When the woven bag disengages from the main body 1, the pressing rod 704 will guide the woven bag to fall into the collection box 901 through the guiding plate 902. When the number of woven bags in the collection box 901 reaches a certain amount, the handle can be pulled to take out the woven bags in the collection box 901. The cut woven bags are separated from the uncut woven bags through the movement of the collection box 901, allowing the cut woven bags to fall to the designated position, playing the role of storage and stacking. At the same time, after this device moves the woven bag to the corresponding position, it can position and fix it, so that the woven bag does not shift during the slitting process, can accurately cut the specified position of the woven bag, and is also convenient for collecting the woven bags, greatly improving the work efficiency.

[0021] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
