Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag production, specifically to a fixing auxiliary device for plastic woven bag production. Background Technology

[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. Their raw materials are generally polyethylene, polypropylene, and other chemical plastic raw materials. Plastic woven bags can be divided into packaging bags for industrial and agricultural products, food packaging bags, and materials for tourism and transportation.

[0003] Equipment used in the technology has revealed that during the production process, plastic woven bags need to be sewn together. Because plastic woven bags are relatively soft and there is no auxiliary structure to fix them, they are prone to shifting during sewing, which makes sewing difficult and significantly reduces work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, a fixing auxiliary device for the production of plastic woven bags is provided. This technical solution solves the problem mentioned in the background art that plastic woven bags need to be sewn during the production process. Because plastic woven bags are relatively soft, without an auxiliary structure to fix them, they are prone to displacement during sewing, which is not conducive to sewing and thus leads to a significant reduction in work efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fixed auxiliary device for producing plastic woven bags includes a conveyor table, with support bars on the front and rear sides of the conveyor table, a mounting frame fixedly installed on the top of the support bars, a moving mechanism on the top of the mounting frame, and a fixing mechanism on the bottom of the mounting frame.

[0007] The fixing mechanism includes a movable block, on which first connecting rods are rotatably mounted on the front and rear sides. Four sets of first connecting rods are provided, and the other ends of the four sets of first connecting rods are rotatably mounted on the top of the pressure plate. A fixing plate is provided on the right side of the movable block. Two sets of fixing plates are provided, with the other set of fixing plates located at the bottom of the movable block. A second lead screw is rotatably mounted on the inner side of the two sets of fixing plates. A second guide rod is also provided on the inner side of the two sets of fixing plates. One end of the second lead screw is fixedly mounted on the output end of the second motor.

[0008] Preferably, the outer surface of the second lead screw is threaded with a slider, the slider is also slidably mounted on the outer surface of the second guide rod, the bottom end of the slider is movably connected to the connecting block through the second connecting rod, and the second connecting rod is provided in two sets, the connecting block is rotatably mounted on the inner side of the first connecting rod in two sets.

[0009] Preferably, the top of the mounting bracket has two sets of sliding grooves.

[0010] Preferably, the moving mechanism includes a mounting plate, two sets of mounting plates are provided, and the mounting plates are located at the ends of the corresponding slide grooves. A first lead screw is rotatably mounted on the inner side of the mounting plate, and a first guide rod is also provided on the inner side of the mounting plate. One end of the first lead screw is fixedly mounted on the output end of the first motor.

[0011] Preferably, the fixing mechanism is provided in two sets, and the two sets of fixing mechanisms are symmetrically arranged on the conveyor table.

[0012] Preferably, the two sets of threads on the outer surface of the first lead screw have opposite directions of rotation, and the outer surface of the first lead screw is threadedly connected to two sets of movable blocks, which are also slidably mounted on the outer surface of the first guide rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] First, by incorporating a fixing mechanism, a second motor drives a second lead screw to rotate, causing a slider to move along a second guide rod. This, in turn, causes the first connecting rod to rotate via a second connecting rod and a connecting block, pushing a pressure plate downwards to press the plastic woven bag, thus achieving stable fixing of the woven bag and ensuring that it will not move during sewing. Second, by incorporating a moving mechanism, a first motor drives a first lead screw to rotate. Because the two sets of threads on the outer surface of the first lead screw rotate in opposite directions, the two fixing mechanisms can move towards or away from each other along the first guide rod. This allows for adaptability to plastic woven bags of different sizes. The position of the fixing mechanism can be flexibly adjusted according to the size of the woven bag and the sewing position requirements, thereby adapting to the fixing needs of different specifications of plastic woven bags and enhancing the applicability and flexibility of the device.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Reference Figure 1-3 As shown, a fixing auxiliary device for producing plastic woven bags includes a conveyor table 1. Support bars 2 are provided on the front and rear sides of the conveyor table 1. A mounting frame 3 is fixedly installed on the top of the support bars 2. A moving mechanism 4 is provided on the top of the mounting frame 3, and a fixing mechanism 5 is provided at the bottom of the mounting frame 3. The fixing mechanism 5 includes a movable block 501. Two sets of fixing mechanisms 5 are provided, symmetrically arranged on the conveyor table 1. First connecting rods 502 are rotatably installed on the front and rear sides of the movable block 501. Four sets of first connecting rods 502 are provided, with the other ends of all four sets rotatably mounted on the top of a pressure plate 503. A fixing plate 504 is provided on the right side of the movable block 501. Two sets of 504 are provided. Another set of fixed plates 504 is located at the bottom of the movable block 501. The inner side of the two sets of fixed plates 504 is rotatably mounted with a second lead screw 505. The inner side of the two sets of fixed plates 504 is also provided with a second guide rod 506. One end of the second lead screw 505 is fixedly installed at the output end of the second motor 507. The outer surface of the second lead screw 505 is threadedly connected with a slider 508. The slider 508 is also slidably installed on the outer surface of the second guide rod 506. The bottom end of the slider 508 is movably connected to the connecting block 510 through the second connecting rod 509. Two sets of the second connecting rod 509 are provided. The connecting block 510 is rotatably installed on the inner side of two sets of first connecting rods 502.

[0025] In this solution, the second motor 507 drives the second lead screw 505 to rotate, so that the slider 508, which is threaded to the outer surface of the second lead screw 505, can slide along the second guide rod 506. When the slider 508 moves, the first connecting rod 502 is driven to rotate through the second connecting rod 509 and the connecting block 510, thereby realizing the up and down movement of the pressure plate 503. This achieves the function of fixing and releasing the plastic woven bag, which can stably fix the plastic woven bag according to production needs, ensure its positional accuracy during the production process, and improve production efficiency and product quality.

[0026] Reference Figure 1-2 As shown, the top of the mounting bracket 3 is provided with two sets of sliding grooves 301. The moving mechanism 4 includes a mounting plate 401. Two sets of mounting plates 401 are provided, and the mounting plates 401 are located at the ends of the corresponding sliding grooves 301. A first lead screw 402 is rotatably mounted on the inner side of the mounting plate 401. A first guide rod 403 is also provided on the inner side of the mounting plate 401. One end of the first lead screw 402 is fixedly mounted on the output end of the first motor 404. Two sets of threads with opposite directions are opened on the outer surface of the first lead screw 402. Two sets of movable blocks 501 are threadedly connected to the outer surface of the first lead screw 402. The two sets of movable blocks 501 are also slidably mounted on the outer surface of the first guide rod 403.

[0027] In this scheme, the first motor 404 drives the first lead screw 402 to rotate, so that the two sets of movable blocks 501 threaded to the outer surface of the first lead screw 402 can move towards or away from each other along the first guide rod 403. This allows the fixing mechanism 5 to flexibly adjust the width of the two fixing mechanisms 5 according to the size and position requirements of the plastic woven bag, thereby improving the applicability and ease of operation of the device.

[0028] The working principle of this utility model is as follows: In use, firstly, the woven bag is placed on the conveyor table 1, and the first motor 404 is started. Its output end drives the first lead screw 402 to rotate. Since the two sets of threads on the outer surface of the first lead screw 402 rotate in opposite directions, and the two sets of movable blocks 501 are threadedly connected to the outer surface of the first lead screw 402 and slidably mounted on the outer surface of the first guide rod 403, when the first lead screw 402 rotates, the two sets of movable blocks 501 will move towards or away from each other along the first guide rod 403, thereby driving the two sets of fixed mechanisms 5 to move according to the plastic... To meet the size and position requirements of the woven plastic bag, the width of the two sets of fixing mechanisms 5 is flexibly adjusted. Next, the second motor 507 is started, and its output end drives the second lead screw 505 to rotate. When the second lead screw 505 rotates, the slider 508 slides along the second guide rod 506. When the slider 508 moves, it drives the two sets of first connecting rods 502 to rotate through the two sets of second connecting rods 509 and connecting blocks 510. The rotation of the first connecting rods 502 drives the pressure plate 503 to move up and down, thereby realizing the fixing and release of the plastic woven bag to meet the needs of the staff.
