Description
Technical Field
[0001] This utility model relates to the field of woven bag cutting technology, specifically a positioning and cutting device for woven bag production. Background Technology
[0002] Woven bags are one of the most widely used packaging materials in daily life. Their raw materials are generally various chemical plastics such as polyethylene and polypropylene. During the production process of woven bags, cutting devices are needed to cut the woven bags.
[0003] Existing woven bag cutting devices can only cut woven bag material in one direction, and often require multiple rounds of cutting to achieve the specified length and width of the bag material. Since woven bag material is relatively light, it is necessary to position the woven bag material before cutting to ensure sufficient cutting and improve the cutting effect.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a positioning and cutting device for woven bag production, in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this invention is to provide a positioning and cutting device for woven bag production, so as to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is a positioning and cutting device for woven bag production, including a workbench, a conveyor belt, a first cutting mechanism, a second cutting mechanism, and an adjusting mechanism. A cutting cavity is formed in the workbench, and the conveyor belt passes through the lower part of the cutting cavity. Multiple pairs of parallel support blocks are fixed on the conveyor belt. The first cutting mechanism and the second cutting mechanism are sequentially arranged above the conveyor belt within the cutting cavity. The first cutting mechanism includes a first hydraulic cylinder, a connecting plate, a pressure arm, a damper, a pressure block, a cutting machine, a first cutting blade, and an air hole. The output end of the hydraulic cylinder is fixedly connected downwards to the connecting plate, and the pressure arm is fixed at each of the four corners of the connecting plate. The pressure arm extends downward and is fixedly connected to the damper at the bottom. The pressure block is fixed at the bottom of the damper. The cutting machine is fixed at the bottom of the connecting plate. The first cutting blade is provided below the cutting machine. The first cutting blade is parallel to the conveyor belt conveying direction. The horizontal height of the pressure block is lower than the first cutting blade. The second cutting mechanism has the same structure as the first cutting mechanism. The second cutting blade of the second cutting mechanism is perpendicular to the conveyor belt conveying direction. The second hydraulic cylinder of the second cutting mechanism is fixed at the top of the cutting cavity. The worktable is located directly above the first cutting mechanism and has a placement cavity. The adjustment mechanism is provided in the placement cavity.
[0007] Furthermore, the adjustment mechanism includes a servo motor, a worm gear, a worm wheel, a screw, a slide bar, a moving block, a moving rod, a connecting rod, and a support block. The servo motor is located on one side of the placement cavity. The output end of the servo motor is fixedly connected to the worm gear. The end of the worm gear away from the servo motor is rotatably connected to the support block. The worm wheel is sleeved and fixed at the end of the screw, and the worm wheel cooperates with the worm gear. Both ends of the screw are rotatably connected to the inner wall of the placement cavity. Both ends of the slide bar are fixedly connected to the inner wall of the placement cavity. The screw and the slide bar are parallel. Two slidable moving blocks are sleeved on both the slide bar and the screw. A pair of corresponding moving blocks are fixedly connected by the moving rod.
[0008] Furthermore, the surface of the slide bar is smooth, the inner wall of the moving block on the slide bar is smooth, and the inner wall of the moving block on the screw is provided with a thread that matches the screw.
[0009] Furthermore, two parallel sliding grooves are provided on the partition between the placement cavity and the cutting cavity. Each of the two moving rods is fixed with two connecting rods that extend vertically into the cutting cavity through the sliding grooves. The bottoms of the two pairs of connecting rods are fixedly connected to the first hydraulic cylinder. The sliding grooves are located directly above the support blocks, and the length of the sliding grooves is shorter than the spacing between each pair of support blocks.
[0010] The beneficial effect of adopting the above-mentioned further solution is that by starting the servo motor, the worm gear drives the worm wheel to rotate, thereby causing the screw to rotate. With the cooperation of the screw, the moving block, and the slider, the moving rod can move in the placement cavity. The connecting rod at the bottom of the moving rod drives the first hydraulic cylinder in the cutting cavity to move, thereby adjusting the cutting position of the first cutting blade. At the same time, the length limitation of the slide groove limits the cuttable position of the first cutting blade.
[0011] Furthermore, each pair of support blocks cooperates with the pressure block above, and the support blocks are provided with woven bag material.
[0012] Furthermore, the partition at the bottom of the cutting cavity is located between the upper and lower conveyor belts of the conveyor belt and is close to the upper conveyor belt. Furthermore, the pressure block has a vertically penetrating air hole.
[0013] The beneficial effect of adopting the above-mentioned further solution is that when the output end of the hydraulic cylinder presses down, it will drive the airflow above the woven bag material, which will affect the position of the woven bag material on the conveyor belt and affect the subsequent cutting. By setting up a damper and a pressure block, when the output end of the hydraulic cylinder presses down, the pressure block presses down and contacts the woven bag material first, while squeezing the support block. Together with the partition plate at the bottom of the conveyor cavity, which plays a supporting role, the woven bag material to be cut is fixed. Positioning is achieved by the pressure block contacting and squeezing the woven bag material first. By opening air holes in the pressure block, the influence of airflow on the woven bag material when pressing down can be reduced.
[0014] Furthermore, the output ends of the first hydraulic cylinder and the second hydraulic cylinder move downwards. When the damper is fully contracted, the bottom of the first cutting blade and the bottom of the second cutting blade are both lower than the top surface of the support block and higher than the bottom surface of the support block.
[0015] The advantage of adopting the above-mentioned further solution is that it limits the height of the cutting blade, ensuring that the cutting blade completely cuts the woven bag material while avoiding the cutting blade touching the conveyor belt.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: By providing a first cutting mechanism and a second cutting mechanism, the hydraulic cylinder is activated, and the output end of the hydraulic cylinder presses down to drive the connecting plate to move down. At this time, the pressure plate first contacts the edge of the woven bag material and simultaneously squeezes the support block. With the help of the partition plate at the bottom of the conveyor cavity, which plays a supporting role, the woven bag material to be cut is fixed. At this time, the output end of the hydraulic cylinder continues to press down, so that the cutting blade of the cutting machine touches the woven bag material and cuts it, thereby realizing the positioning and cutting of the woven bag material and improving the cutting effect. The first cutting blade is parallel to the conveyor belt conveying direction, and the second cutting blade is perpendicular to the conveyor belt conveying direction. By providing cutting blades with different orientations and cooperating with the provided adjustment mechanism to adjust the cutting position of the first cutting blade, woven bag material of specified length and width can be cut, reducing the number of cutting rounds and improving the cutting efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1 - Figure 5This utility model provides a technical solution: Multiple pairs of parallel support blocks 2001 are fixed on the conveyor belt of the conveyor belt 200. Each pair of support blocks 2001 cooperates with the upper pressure block 3005. Woven bag material 600 is provided on the support block 2001. The partition at the bottom of the cutting cavity 1001 is located between the upper and lower conveyor belts of the conveyor belt 200 and close to the upper conveyor belt. Through the provision of a damper 3004 and the pressure block 3005, when the output end of the hydraulic cylinder 3001 presses down, the pressure block 3005 first contacts the edge of the woven bag material, simultaneously squeezing the support block 2001, cooperating with the upper conveyor belt... The partition below the belt, which provides support, fixes the woven bag material to be cut. The pressure block 3005 has a vertically penetrating air hole 3008. The output ends of the first hydraulic cylinder 3001 and the second hydraulic cylinder 4001 move downward. When the damper 3004 is fully retracted, the bottom of the first cutting blade 3007 and the bottom of the second cutting blade 4002 are both lower than the top surface of the support block 2001 and higher than the bottom surface of the support block 2001. By limiting the minimum height of the cutting blade when it moves downward, it is ensured that the cutting blade completely cuts the woven bag material without touching the conveyor belt 200.
[0029] Specifically, the working principle and usage of this positioning and cutting device for woven bag production are as follows: Before use, check whether all components are intact. Then, adjust the position of the first cutting mechanism 200 according to the required length and width of the woven bag to be cut using the adjusting mechanism 500. By starting the servo motor 5001, the worm gear 5002 drives the worm wheel 5003 to rotate, thereby causing the screw 5004 to rotate. With the cooperation of the screw 5004, the moving block 5006, and the slider 5005, the moving rod 5007 can move within the placement cavity 1002. Through the connecting rod 5008 at the bottom of the moving rod 5007, the first hydraulic cylinder 3001 in the cutting cavity 1001 moves, thereby adjusting the cutting position of the first cutting blade 3007. After adjustment, the servo motor 5001 is turned off, and then the conveyor belt 200 is started, so that the woven bag material on the conveyor belt is cut sequentially by the first cutting mechanism 300 and the second cutting mechanism 400. The working of the first cutting mechanism 200 and the second cutting mechanism 400... The operation is consistent. By activating the first hydraulic cylinder 3001, the output end of the first hydraulic cylinder 3001 presses down, causing the connecting plate 3002 to move downward. At this time, the pressure plate 3005 first contacts the edge of the woven bag material, and at the same time squeezes the support block 2001. With the help of the partition plate at the bottom of the conveyor belt, which plays a supporting role, the woven bag material to be cut is fixed. At this time, the output end of the first hydraulic cylinder 3001 continues to press down, so that the cutting blade 3007 of the cutting machine 3006 touches the woven bag material and cuts it, thereby realizing the positioning and cutting of the woven bag material and improving the cutting effect. The first cutting blade 3007 is parallel to the conveying direction of the conveyor belt 200, and the second cutting blade 4002 is perpendicular to the conveying direction of the conveyor belt 200. By setting the cutting blades with different orientations, and with the adjustment mechanism 500 to adjust the cutting position of the first cutting blade 3007, woven bag material of a specified length and width can be cut, reducing the number of cutting rounds and improving the cutting efficiency. This practical structure is simple, easy to use, and has high practical value.
