Description

Technical Field

[0001] This utility model relates to the field of shearing equipment technology, and more specifically, it relates to a shearing device for processing woven bags. Background Technology

[0002] Woven bags, primarily made of polypropylene or polyethylene plastic flat yarns, are a widely used packaging material, commonly used for packaging bulk commodities such as grains, fertilizers, cement, chemical raw materials, feed, and building materials. In its complete production and use chain, "cutting" is a crucial link. The production process of woven bags typically involves: yarn drawing – weaving – coating / lamination – printing – cutting – sewing. The fabric coming off the weaving machine is a continuous tubular material and must be cut to the specific length required by the customer to become an individual bag. The most common woven bag cutting equipment is the cutting machine. However, existing cutting machines have some problems and shortcomings, which can affect the cutting of woven bags.

[0003] Firstly, in the current use of cutting machines, after the woven bags are cut, the woven bags are left at the exit position of the cutting blade of the cutting machine. Transportation relies on manual operation, resulting in poor automation of the equipment and thus low working efficiency.

[0004] Secondly, the transportation of woven bags is quite messy, requiring them to be sorted and processed again at the next stage. This cumbersome process reduces the functionality of the equipment and consequently lowers its production efficiency.

[0005] In addition, the transportation of equipment relies heavily on manual labor. Stacking too many woven bags increases the weight, is time-consuming and labor-intensive, and increases the transportation cost of the equipment, thus resulting in higher operating costs. Utility Model Content

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides a cutting device for woven bag processing to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a shearing device for woven bag processing, comprising a machine body, a conveying device mounted on the machine body, the conveying device including a mounting frame, the bottom end of the mounting frame being connected to the top end of the machine body, a long groove on the mounting frame, a fixed block rotatably connected to the long groove, an electric push rod on the fixed block, a rotating shaft on the electric push rod, a support arm rotatably connected to the mounting frame, a mounting seat on the support arm, the rotating shaft passing through the mounting seat and rotatably connected to the support arm, a guide rail on the support arm, a conveying plate slidably connected to the guide rail, a receiving device at the top end of the machine body, the receiving device including a module plate, a drive shaft on the module plate, a second motor on the drive shaft, a flip plate on the drive shaft, a slot on the flip plate, a buckle on the slot, a receiving box at one end of the buckle, a roller at the bottom end of the receiving box, and a feeding device at the top end of the machine body.

[0008] This utility model is further configured such that: a lead screw is provided at the bottom end of the support arm, and a sleeve is threadedly connected to the lead screw; one end of the sleeve is connected to one end of the conveyor plate; a motor is provided with the lead screw. After the machine body finishes cutting the woven bag, the woven bag falls onto the machine body. During this process, an electric push rod is activated to extend and retract. As the electric push rod extends, it drives the rotating shaft connected to it to support the mounting base, causing the support arm connected to the mounting base to rotate on the mounting frame. As the angle of the support arm changes, the electric push rod drives the fixed block to rotate and adjust on the long groove. By raising the conveyor plate, the woven bag falls directly onto the conveyor plate. During this process, if the conveyor plate is far away, the motor is activated to rotate, causing it to drive the lead screw on the support arm to rotate accordingly. Through the threaded connection between the lead screw and the sleeve, the motor drives the support arm to rotate. The sleeve-connected conveyor plate slides along the guide rail, pulling the conveyor plate and the output end of the machine body closer together. This facilitates direct collection of woven bags by the conveyor plate, reducing manual intervention, increasing the automation level of the equipment, and thus improving its working efficiency. During this process, after the conveyor plate has finished collecting, the electric push rod one is activated to retract, causing the conveyor plate to rotate to a vertical position. At the same time, the motor two is activated to rotate, causing the drive shaft to rotate on the module plate. The receiving box, connected to the flip plate by a buckle, is placed at the bottom of the conveyor plate to collect the falling woven bags. During the rotation of the receiving box, it is supported by the rollers at the bottom. After collection, the receiving box is slid out of the slot and transported by the rollers. This reduces the difficulty of conveying the equipment, improves the ease of movement, and thus increases the production efficiency of the equipment.

[0009] The present invention is further configured such that: a partition is provided at the top of the conveyor plate; during the rotation of the conveyor plate, in order to prevent the woven bags from falling into the gap between the conveyor plate and the mounting frame, a partition is added so that the partition changes shape with the rotation to cover the gap, thereby improving the collection stability of the equipment.

[0010] This utility model is further configured such that: the feeding device includes a positioning frame, the bottom end of which is connected to the top end of the machine body; an adjusting frame is slidably connected to the top end of the positioning frame; an adjusting knob is provided on the adjusting frame; a shaft hole is provided on the adjusting frame; a positioning shaft is fitted on the shaft hole; a feeding roller is provided on the positioning shaft; a drive gear and a driven gear are respectively provided at one end of the two sets of positioning shafts; the driven gear meshes with the drive gear; a positioning plate is provided at the other end of the drive gear and the driven gear; and a motor is provided on the positioning plate. During the conveying process, the adjusting frame is slid to align with the outlet of the machine body; the position of the adjusting frame and the positioning frame is fixed by rotating the adjusting knob; during this process, the motor is started to rotate on the positioning plate; the rotation drives the drive gear connected to it to rotate; and the meshing relationship between the drive gear and the driven gear drives the two sets of drive shafts to rotate in opposite directions, thereby driving the feeding roller to rotate, directly pulling the woven bag at the outlet and making it fall accurately onto the conveyor plate, thereby improving the cleanliness of the equipment, reducing subsequent sorting steps, and improving the production efficiency of the equipment.

[0011] The present invention is further configured such that: an electric push rod II is provided on the conveyor plate, and a clamping frame is provided at the output end of the electric push rod II. When the woven bag falls onto the conveyor plate and the conveyor plate rotates in a concentrated manner, in order to prevent the woven bag from sliding and scattering due to the rotation of the conveyor plate, the electric push rod II is activated to retract, so that it drives the clamping frame to gather the woven bag, so that it can fall accurately into the receiving box, thereby improving the automation level of the equipment and thus improving the working efficiency of the equipment.

[0012] The present invention is further configured such that: the clamping frame is provided with a through hole, the through hole is slidably connected to a clamping shaft, the clamping shaft is equipped with a spring, one end of the spring is connected to one end of the clamping frame, and the clamping shaft is provided with a top block. During the clamping process, in order to prevent the woven bag from being fixed in the center and the two ends from falling apart, causing the two ends of the woven bag to bend and not fall into the receiving box in an orderly manner, a clamping shaft is added to the clamping frame so that it slides along the through hole. After the top block collides with the woven bag, it drives the clamping shaft to slide in the through hole. The spring rebounds the clamping shaft, thereby improving the neatness of the equipment's collection and thus improving the working efficiency of the equipment.

[0013] The present invention is further configured such that: a rubber pad is provided on the feeding roller, which prevents the woven bag from running off-center during the conveying process. The addition of the rubber pad increases the friction of the feeding roller, improves the conveying stability of the equipment, and thus improves the working efficiency of the equipment.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention has the following beneficial effects: 1. After the machine body finishes cutting the woven bags, the woven bags fall onto the machine body. During this process, the electric push rod is activated to extend and retract. As the electric push rod extends, it drives the rotating shaft connected to it to support the mounting base, causing the support arm connected to the mounting base to rotate on the mounting frame. As the angle of the support arm changes, the electric push rod drives the fixed block to rotate and adjust on the long groove. By raising the conveyor plate, the woven bags fall directly onto the conveyor plate. During this process, if the conveyor plate is far away, the motor is activated to rotate, causing the lead screw on the support arm to rotate accordingly. Through the threaded connection between the lead screw and the sleeve, the conveyor plate connected to the sleeve slides along the guide rail, pulling the conveyor plate and the output end of the machine body closer together. This facilitates the direct collection of woven bags by the conveyor plate, reduces manual intervention, and improves the automation level of the equipment. 2. After the conveyor plate has finished collecting, start the electric push rod one to retract, causing the conveyor plate to rotate to a vertical position. During this process, start the motor two to rotate, causing the drive shaft to rotate on the module plate. Place the receiving box, which is connected to the flip plate by a buckle, at the bottom of the conveyor plate to collect the falling woven bags. The receiving box is supported by the rollers at the bottom during rotation. After collection, slide the receiving box to pull it out in the slot and transport it by the rollers. This reduces the difficulty of conveying the equipment, improves the convenience of the equipment's movement, and thus improves the production efficiency of the equipment. 3. During the conveying process, the sliding adjustment frame is aligned with the machine's outlet. The positions of the adjustment frame and positioning frame are fixed by rotating the adjustment knob. During this process, the motor is started and rotated on the positioning plate. The rotation drives the connected drive gear to rotate. Through the meshing relationship between the drive gear and the driven gear, the two sets of drive shafts rotate in opposite directions, thereby driving the feeding roller to rotate. This directly pulls the woven bag at the outlet, causing it to fall accurately onto the conveyor plate. This improves the cleanliness of the equipment, reduces subsequent sorting steps, and increases the production efficiency of the equipment. Attached Figure Description

[0021] In the embodiments of this application: a lead screw 19 is provided at the bottom end of the support arm 7, and a sleeve 20 is threadedly connected to the lead screw 19. One end of the sleeve 20 is connected to one end of the conveyor plate 10. A motor 21 is provided with the lead screw 19. After the machine body 1 finishes cutting the woven bag, the woven bag falls onto the machine body 1. During this process, the electric push rod 5 is activated to extend and retract. During the extension of the electric push rod 5, it drives the rotating shaft 6 connected to it to support the mounting base 8, causing the support arm 7 connected to the mounting base 8 to rotate on the mounting frame 2. As the angle of the support arm 7 changes, the electric push rod 5 drives the fixing block 4 to rotate and adjust on the long groove 3. By raising the conveyor plate 10, the woven bag falls directly onto the conveyor plate 10. During this process, the conveyor plate 10 may be far away. The motor 21 is activated to rotate, so that the woven bag falls onto the support arm 7. The upper drive screw 19 rotates accordingly. Through the threaded connection between the screw 19 and the sleeve 20, the conveyor plate 10 connected to the sleeve 20 slides along the guide rail 9, pulling the conveyor plate 10 and the output end of the machine body 1 inward, so that the conveyor plate 10 can directly collect the woven bags. During this process, after the conveyor plate 10 has finished collecting, the electric push rod 5 is activated to retract, driving the conveyor plate 10 to rotate into a vertical state. During this process, the motor 13 is activated to rotate, causing the drive shaft 12 to rotate on the module plate 11, placing the receiving box 17 connected to the flip plate 14 through the buckle 16 at the bottom of the conveyor plate 10, so that it can collect the falling woven bags. During the rotation of the receiving box 17, it is supported by the rollers 18 at the bottom. After collection, the receiving box 17 is slid to be pulled out in the slot 15 and transported by the rollers 18.

[0022] More specifically: a spacer 22 is provided at the top of the conveyor plate 10. During the rotation of the conveyor plate 10, in order to prevent the woven bag from falling into the gap between the conveyor plate 10 and the mounting frame 2, the spacer 22 is installed so that the spacer 22 changes shape with the rotation to cover the gap.

[0023] More specifically: the feeding device includes a positioning frame 23, the bottom end of which is connected to the top end of the machine body 1. An adjusting frame 24 is slidably connected to the top end of the positioning frame 23. An adjusting knob 25 is provided on the adjusting frame 24. A shaft hole 26 is provided on the adjusting frame 24, and a positioning shaft 27 is fitted onto the shaft hole 26. A feeding roller 28 is provided on the positioning shaft 27. A drive gear 29 and a driven gear 30 are respectively provided at one end of each of the two sets of positioning shafts 27. The driven gear 30 meshes with the drive gear 29. A positioning piece 31 is provided at the other end of the drive gear 29 and the driven gear 30. The positioning plate 31 is equipped with a motor 32. During the conveying process, the sliding adjustment frame 24 is aligned with the outlet of the machine body 1. The positions of the adjustment frame 24 and the positioning frame 23 are fixed by rotating the adjustment knob 25. During this process, the motor 32 is started to rotate on the positioning plate 31. The rotation drives the drive gear 29 connected to it to rotate. Through the meshing relationship between the drive gear 29 and the driven gear 30, the two sets of drive shafts 12 are driven to rotate in opposite directions, thereby driving the feeding roller 28 to rotate. The woven bag at the outlet is directly pulled and accurately falls onto the conveyor plate 10.

[0024] More specifically: The conveyor plate 10 is equipped with an electric push rod 39, and the output end of the electric push rod 39 is equipped with a clamping frame 33. When the woven bag falls onto the conveyor plate 10 and the conveyor plate 10 rotates in a concentrated manner, in order to prevent the woven bag from sliding and scattering due to the rotation of the conveyor plate 10, the electric push rod 39 is activated to retract, so that it drives the clamping frame 33 to gather the woven bag and make it fall accurately into the receiving box 17.

[0025] More specifically: the clamping frame 33 is provided with a through hole 34, and a clamping shaft 35 is slidably connected to the through hole 34. A spring 36 is provided on the clamping shaft 35, one end of the spring 36 is connected to one end of the clamping frame 33, and a top block 37 is provided on the clamping shaft 35. During the clamping process of the clamping frame 33, in order to prevent the center of the woven bag from being fixed and the two ends from falling apart, causing the two ends of the woven bag to bend and not fall into the receiving box 17 in an orderly manner, a clamping shaft 35 is added to the clamping frame 33 so that it slides along the through hole 34. After the top block 37 collides with the woven bag, it drives the clamping shaft 35 to slide in the through hole 34, and the spring 36 rebounds the clamping shaft 35.

[0026] More specifically: a rubber pad 38 is provided on the feeding roller 28 to prevent the woven bag from deviating during the conveying process, and the rubber pad 38 is added to increase the friction of the feeding roller 28.

[0027] In summary, during the conveying process, the sliding adjustment frame 24 is aligned with the outlet of the machine body 1. The positions of the adjustment frame 24 and the positioning frame 23 are fixed by rotating the adjustment knob 25. During this process, the motor 32 is started and rotates on the positioning plate 31. This rotation drives the connected drive gear 29 to rotate. The meshing relationship between the drive gear 29 and the driven gear 30 drives the two sets of drive shafts 12 to rotate in opposite directions, thereby driving the feeding roller 28 to rotate. This directly pulls the woven bag at the outlet, ensuring it falls precisely onto the conveyor plate 10. After the machine body 1 has finished cutting the woven bag, the bag falls onto the machine body 1. During this process, the motor 32 is started. The electric push rod 5 extends and retracts. During the extension of the electric push rod 5, it drives the rotating shaft 6 connected to it to support the mounting base 8, causing the support arm 7 connected to the mounting base 8 to rotate on the mounting frame 2. As the angle of the support arm 7 changes, the electric push rod 5 drives the fixing block 4 to rotate and adjust on the long groove 3. By raising the conveyor plate 10, the woven bag falls directly onto the conveyor plate 10. During this process, if the conveyor plate 10 is far away, the motor 21 is started to rotate, causing it to drive the lead screw 19 to rotate on the support arm 7. Through the threaded connection between the lead screw 19 and the sleeve 20, the conveyor plate 10 connected to the sleeve 20 is driven to move along the guide rail 9. The conveyor plate 10 and the output end of the machine body 1 are pulled inwards to facilitate direct collection of woven bags by the conveyor plate 10. During this process, after the conveyor plate 10 has finished collecting, the electric push rod 5 is activated to retract, causing the conveyor plate 10 to rotate and become vertical. When the woven bags fall onto the conveyor plate 10 and the conveyor plate 10 rotates in a concentrated manner, in order to prevent the woven bags from sliding and scattering due to the rotation of the conveyor plate 10, the electric push rod 39 is activated to retract, causing it to drive the clamping frame 33 to gather the woven bags, so that they can fall accurately into the collection box 17. During the clamping process of the clamping frame 33, in order to prevent the woven bags from being fixed in the center and scattered at both ends, causing the ends of the woven bags to bend and not fall into the collection box in an orderly manner, the clamping frame 33 is activated to retract, causing it to drive the clamping frame 33 to gather the woven bags. Inside 17, a clamping shaft 35 is installed on the clamping frame 33, allowing it to slide along the through hole 34. After the top block 37 collides with the woven bag, it drives the clamping shaft 35 to slide within the through hole 34. The spring 36 then rebounds the clamping shaft 35. During this process, the second motor 13 is started to rotate, causing the drive shaft 12 to rotate on the module plate 11. The receiving box 17, connected to the flip plate 14 via the buckle 16, is placed at the bottom of the conveyor plate 10 to collect the falling woven bags. During rotation, the receiving box 17 is supported by the rollers 18 at the bottom. After collection, the receiving box 17 is slid out of the slot 15 and transported by the rollers 18.
