A spring 710 is sleeved on the outer surface of the damper 78. One end of the spring 710 is fixed to the top side wall of the positioning plate 79, and the other end of the spring 710 is fixed to the bottom side wall of the transmission plate 77. Through the setting of the positioning component 7, the woven bag is pressed better, and the woven bag is effectively prevented from loosening or even detaching, which greatly improves the pressing and positioning effect of the woven bag, can effectively reduce the turnover auxiliary time between operations, greatly improve the work efficiency of production and processing, and has strong adaptability.

[0028] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it is worth specifically explaining that a distance adjustment component 8 adapted to the mounting frame b75 is provided on one side of the frame 1, and the distance adjustment component 8 includes two mounting seats 81, and the two mounting seats 81 are symmetrically distributed and fixed on the side wall of one side of the frame 1, and a guide rod 82 is commonly fixed on one side wall of the two mounting seats 81, and two symmetrically distributed guide plates 83 are fixed on one side wall of the mounting frame b75, and one guide plate 83 is slidably sleeved with the outer surface of the guide rod 82, and two symmetrically distributed bearing seats 84 are fixed on one side wall of the frame 1, and the adjacent side walls of the two bearing seats 84 rotate together. A threaded rod 85 is dynamically connected to the frame 1, and another guide plate 83 is threadedly connected to the threaded rod 85. A mounting plate 86 is fixed to a side wall of one side of the frame 1, and a servo motor 87 is fixed to a side wall of one side of the mounting plate 86. One end of the output shaft of the servo motor 87 is coaxially fixed with one end of the threaded rod 85.

[0029] This scheme has the following working process: when auxiliary positioning is required for the production and processing of plastic woven bags, the woven bags are first placed on the conveyor belt 3, and the sprocket 5 is driven by the driving motor 4 to rotate synchronously, and the meshing transmission effect between the sprocket 5 and the chain 6 is used to drive the rotating shaft 2 to rotate synchronously, so that the conveyor belt 3 is operated to transport and move the woven bags until the woven bags move to the position directly below the pressing plate 73, and the pressing plate 73 is driven by the cylinder a72 to move downward after being subjected to force, thereby driving the anti-skid rubber plate 74 to move synchronously until the rubber anti-skid plate fits the woven bag, and the servo motor 87 is driven to make the woven bag fit the rubber anti-skid plate. The threaded rod 85 moves synchronously, and the threaded transmission effect between the threaded rod 85 and one of the guide plates 83 is used to drive the installation frame b75 to move synchronously, ensuring that the positioning plate 79 is located directly above the woven bag. The transmission plate 77 is driven by the cylinder b76 until one side of the positioning plate 79 fits with the woven bag. The elastic effect between the damper 78 and the spring 710 is used to make the positioning plate 79 and the woven bag more compact and fit more closely. After completing the positioning of both sides of the woven bag, the servo motor 87 is rotated counterclockwise to achieve the purpose of stretching and pulling the woven bag, thereby completing the positioning and stretching of the woven bag.

[0030] According to the above working process, it can be known that: through the setting of the positioning component 7, the compression effect on the woven bag is better, and the woven bag is effectively prevented from loosening or even detaching, which greatly improves the compression and positioning effect of the woven bag, can effectively reduce the turnover auxiliary time between operations, greatly improve the work efficiency of production and processing, and has strong adaptability. Through the setting of the distance adjustment component 8, the tension of the woven bag after stretching and positioning can be adjusted according to actual needs, which is beneficial for the staff to sew the sealing part of the woven bag, and can be suitable for processing woven bags of different lengths and specifications, with strong adaptability and flexible and convenient operation.

Through the setting of the guide rods 82, a guiding and limiting function is played on the pressure plate 73, which greatly improves the stability of the pressure plate 73 when rising or falling, and prevents the pressure plate 73 from shaking due to unstable movement.

[0032] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that a limiting ring 9 is fixed at one end of the guide rod 82, and the diameter of the limiting ring 9 is greater than the diameter of the guide rod 82. A plurality of anti-skid grooves 10 are arranged on the side wall of one side of the conveyor belt 3 at equal intervals. The anti-skid grooves 10 are arranged to increase the efficiency of woven bag transmission and prevent the woven bags from slipping when being transported. The limiting ring 9 is arranged to limit the guide rod 82 and prevent the guide rod 82 from being disconnected from the mounting frame a71 due to excessive movement.

[0033] Further as Figure 3 As shown, it is worth explaining in detail that a load-bearing plate 11 is fixed to the side wall of one side of the frame 1, and the load-bearing plate 11 is located on one side of the conveyor belt 3. Two symmetrically distributed support rods 12 are fixed to the side wall of one side of the frame 1, and the other ends of the two support rods 12 are fixed to the bottom side wall of the load-bearing plate 11. Through the arrangement of the load-bearing plate 11 and the support rods 12, the load-bearing plate 11 carries and receives the woven bags, thereby avoiding the situation where the woven bags fall and are inconvenient for the staff to collect.

[0034] Further as Figure 1 and Figure 3 As shown, it is worth specifically explaining that a bottom plate 13 is fixed to the side wall of the bottom end of the frame 1, and the projection area of ​​the bottom plate 13 is greater than the projection area of ​​the frame 1. Through the setting of the bottom plate 13, the overall stability of the frame 1 can be effectively improved to prevent the frame 1 from shaking during operation.

[0035] In summary: through the setting of the guide rod 82, it plays a guiding and limiting role on the pressure plate 73, greatly improving the stability of the pressure plate 73 when rising or falling, preventing the pressure plate 73 from shaking due to instability, and through the setting of the anti-slip groove 10, the woven bag transmission efficiency is increased to prevent the woven bag from slipping when being transported, and through the setting of the limiting ring 9, it plays a limiting role on the guide rod 82 to prevent the guide rod 82 from being disconnected from the mounting frame a71 due to excessive movement, and through the setting of the carrying plate 11 and the support rod 12, the carrying plate 11 carries and receives the woven bag, thereby preventing the woven bag from falling and making it inconvenient for the staff to collect it, and through the setting of the bottom plate 13, the overall stability of the frame 1 can be effectively improved to prevent the frame 1 from shaking during work.
