[0002] A woven bag, which is a kind of plastic bag for packaging, is generally made of various chemical plastic raw materials such as polyethylene and polypropylene. In the production and processing of woven bags, after the woven bags are formed, they are connected end to end, so they cannot be used directly and need to be cut into separate woven bags through cutting before they can be used. The traditional cutting method is to cut at the connection between two adjacent woven bags, so only one woven bag can be cut off at a time, with low cutting efficiency. Moreover, the cutting speed is fast, and users do not have enough reaction time in case of emergencies during work, which poses a great safety hazard and low work safety.
[0003] In view of the above problems, the utility model is improved. Summary of the Invention

[0005] The technical solution of the utility model is realized as follows: A fixed-distance slitter for woven bags includes a first conveying device. In the middle section inside the first conveying device, a second conveying device is installed. On one side of the second conveying device, there is a base. On the top of the base, a frame is fixedly installed. At the bottom inside the frame, a double-shaft motor is fixedly installed. On the output shafts on both sides of the double-shaft motor, special-shaped gears are fixedly installed. Inside the frame, a rotating rod is rotatably installed above the double-shaft motor. At both ends of the rotating rod, turning plates are fixedly installed. On both sides of the surface of the rotating rod, gears are sleeved inside the turning plates, and the gears are meshed with the special-shaped gears.
[0006] For the fixed-distance slitter for woven bags as described above in the utility model, further: At both sides of the bottom of the turning plate, cutting knives are fixedly installed.

[0012] In summary, the beneficial effects of the present utility model are as follows:
[0013] 1. The present utility model adopts an intermittent fixed-distance cutting structure design. The cutting knife will fall at intervals of a certain gap to cut the woven bag, and the head and tail ends of the woven bag are cut simultaneously, so that two woven bags can be cut at one time, which not only improves the cutting efficiency and quality of the woven bag, but also enables the user to have enough reaction time to handle emergencies during work, improves the work safety of the user, and provides convenience for the user's work use.
[0014] 2. Through the setting of the cutting knives in the present utility model, both cutting knives are installed at the bottom of the flipping plate and flip and work along with the flipping of the flipping plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] The following will combine the attached drawings in the embodiments of the present utility modelFigures 1-5 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the protection scope of the present invention. Embodiment
[0026] A fixed-distance slitter for woven bags, comprising a first conveying device 1. A second conveying device 2 is installed in the middle of the inner side of the first conveying device 1. One side of the second conveying device 2 is provided with a base 3. A frame 4 is fixedly installed on the top of the base 3. A double-shaft motor 5 is fixedly installed at the bottom inside the frame 4. Special-shaped gears 6 are fixedly installed on the output shafts on both sides of the double-shaft motor 5. A rotating rod 7 is rotatably installed inside the frame 4 above the double-shaft motor 5. Turning plates 9 are fixedly installed at both ends of the rotating rod 7. Gears 8 are sleeved on both sides of the surface of the rotating rod 7 inside the turning plates 9. The gears 8 are meshed with the special-shaped gears 6.
[0027] The specific usage process is as follows: First, the special-shaped gear 6 is different in appearance from the gear 8. There is a part of the special-shaped gear 6 without teeth. Therefore, when the special-shaped gear 6 and the gear 8 mesh and rotate, when the part without teeth rotates to meet the gear 8, the connection between the special-shaped gear 6 and the gear 8 will be temporarily disconnected. Without the drive of the special-shaped gear 6, the gear 8 will also rotate under the drive of the cutting knife 10 and the turning plate 9. At this time, the cutting knife 10 and the turning plate 9 will automatically fall. Finally, the cutting knife 10 can cut the woven bags passing through on the conveying device 2. And the two cutting knives 10 can cut two adjacent woven bags at the same time, doubling the cutting efficiency of the woven bags. After that, the part of the special-shaped gear 6 with teeth will then mesh with the gear 8 and drive the gear 8 to rotate, thereby driving the turning plate 9 and the cutting knife 10 to turn up and retract. Then the conveying device 1 and the conveying device 2 continue to convey the woven bags. The cutting knife 10 falls again to cut the woven bags, and then turns up and retracts again after cutting, preparing for the next cutting operation. The specific process is to start the double-shaft motor 5 to work. The double-shaft motor 5 drives the two special-shaped gears 6 to rotate at the same time. The two special-shaped gears 6 drive the two gears 8 to rotate at the same time. The two gears 8 drive the rotating rod 7 to rotate. The rotating rod 7 drives the turning plate 9 to turn up and retract. Furthermore, the cutting knife 10 will also follow and retract upward. When the part of the special-shaped gear 6 without teeth rotates to the position of the gear 8, the turning plate 9 and the cutting knife 10 automatically fall to cut the woven bags. After that, the special-shaped gear 6 continues to rotate and the part with teeth meshes with the gear 8 again to drive the gear 8 to rotate. At this time, the turning plate 9 and the cutting knife 10 retract upward, preparing for the next cutting operation. In this way, an intermittent fixed-distance cutting structure design is adopted. The cutting knife will fall to cut the woven bags after a certain interval, and cut the head and tail ends of the woven bags at the same time, which can cut two woven bags at one time, improving both the cutting efficiency and quality of the woven bags, and enabling the user to have enough reaction time to handle emergencies during work, improving the user's work safety and providing convenience for the user's work use. Among them, the buffer mechanism 14 is used to provide buffering for the cutting knife 10 during cutting. On the basis of ensuring that the woven bags can be cut off, it prevents the cutting knife 10 from falling and hitting the conveying device 1 and being damaged mutually, extending the service life of the cutting knife 10 and the conveying device 1, and providing convenience for the user's work use. Specifically as follows, when the cutting knife 10 falls to cut, the cutting knife 10 will fall and contact the support plate 143, then press down the support plate 143. At the same time, the support plate 143 compresses the spring 144. The support plate 143 also slides in the groove 142. Under the action of the spring 144, the force of the cutting knife 10 falling is reduced until it is less than the elastic force of the spring 144. Finally, the spring 144 bounces the support plate 143 back to its original position for subsequent use. The bracket 11, the guiding plate 12, and the adjusting screw 13 form a guiding structure. The two guiding structures are respectively arranged at the feeding end and the discharging end to prevent the woven bags from warping when feeding the woven bags and ensure that the woven bags are smoothly fed into the machine.The guide structure provided at the discharge end can also limit the warping of the woven bag during discharge, ensuring the smooth discharge of the woven bag and providing convenience for the user's work. Specifically, a slope is provided on the side of the guide plate 12 facing the woven bag, and the woven bag will be guided by the slope during transportation. Moreover, the height of the guide plate 12 can also be adjusted by rotating the adjustment screw 13 to meet the actual use requirements and provide convenience for the user's work. It should be noted that in order to ensure the smooth transportation of the woven bag, a guide plate can be provided at the connection of the conveying device 1, the conveying device 2, and the buffer mechanism 14 according to the actual work requirements to prevent the woven bag from being blocked in the machine.
[0028] Cutter knives 10 are fixedly mounted on both sides of the bottom of the flip plate 9 , and buffer mechanisms 14 adapted to the cutter knives 10 are arranged on both sides of the conveying device 2 , and the buffer mechanisms 14 are detachably mounted on the conveying device 1 .
[0029] Specifically, the two cutters 10 are installed at the bottom of the flip plate 9, and they flip and work as the flip plate 9 flips and falls. When the flip plate 9 flips and falls, the woven bags passing through the conveying device 2 are cut and processed, providing convenience for the user's work.
[0030] The buffer mechanism 14 includes a mounting frame 141 fixedly mounted on the conveying device 1, and a groove 142 adapted to the cutter 10 is provided on the top of the mounting frame 141. A support plate 143 adapted to the cutter 10 is slidably mounted inside the groove 142, and springs 144 are fixedly mounted on both sides of the bottom of the support plate 143, and the bottom end of the spring 144 is fixedly connected to the inner wall of the groove 142.
[0031] Specifically, the buffer mechanism 14 is provided to provide a buffer for the cutter 10 when cutting. On the basis of ensuring that the woven bag can be cut, the buffer mechanism 14 is prevented from falling and colliding with the conveying device 1 and damaging each other, thereby extending the service life of the cutter 10 and the conveying device 1, and providing convenience for the user's work. Specifically, when the cutter 10 falls to cut, the cutter 10 will fall and contact the support plate 143, and then the support plate 143 will be pressed down. At the same time, the support plate 143 compresses the spring 144. The support plate 143 also slides in the groove 142. Under the action of the spring 144, the force of the cutter 10 falling is reduced until it is less than the elastic force of the spring 144. Finally, the spring 144 rebounds the support plate 143 to its original position for subsequent use.
[0032] On both sides of the top of the conveying device 1, brackets 11 are erected. Inside the brackets 11, a guiding plate 12 is movably arranged. On both sides of the top of the guiding plate 12, adjusting screws 13 are rotatably installed. The top ends of the adjusting screws 13 penetrate through the tops of the brackets 11, and the adjusting screws 13 are threadedly installed on the brackets 11.
[0033] Specifically, with the settings of the brackets 11, the guiding plate 12, and the adjusting screws 13, the brackets 11, the guiding plate 12, and the adjusting screws 13 form a guiding structure. Two guiding structures are respectively arranged at the feeding end and the discharging end. When the woven bag is fed, it can prevent the woven bag from warping, ensuring that the woven bag is smoothly fed into the machine. The guiding structure arranged at the discharging end can also limit the warping of the woven bag during discharging, ensuring the smooth discharging of the woven bag, providing convenience for the user's work. Specifically, a slope is provided on the side of the guiding plate 12 facing the woven bag. The woven bag will be guided by this slope during transportation. Moreover, the height of the guiding plate 12 can be adjusted by rotating the adjusting screws 13 to meet the actual use requirements, providing convenience for the user's work.
[0034] Mounting blocks 15 are sleeved on the output shafts on both sides of the dual-axis motor 5, and the bottoms of the mounting blocks 15 are fixedly connected to the inner wall of the frame 4.
[0035] Specifically, with the setting of the mounting blocks 15, the mounting blocks 15 are mounted on the output shafts of the dual-axis motor 5 to provide support and fixation for the output shafts of the dual-axis motor 5, improving the stability of the dual-axis motor 5 during operation and providing convenience for the user's work.
