Description

Technical Field

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

[0002] The winding device used in woven bag production is a key piece of equipment in the later stages of the woven bag production line. Its main function is to neatly and tightly wind the flat woven fabric, after processes such as printing and cutting, into rolls under constant tension, so as to facilitate subsequent storage, transportation, or further processing. In the continuous production of woven bags, from drawing and weaving to the finished product, the stability and quality of the winding process directly affect the roll shape and performance of the final product. For example, the prior art represented by the prior art document "A winding device for woven bag production" (publication number CN223280277U) uses the cooperation between the side plate, slot, screw, moving ring and nut to facilitate the removal and replacement of the fully wound roller. This solves the problem that existing winding devices for woven bag production are not easy to remove and replace the roller after winding, thus affecting the winding efficiency.

[0003] However, its structure still needs improvement, as detailed below: Existing equipment often uses bolts or complex locking mechanisms to secure one end of the take-up roller. When changing a fully rolled woven bag, operators must use tools to loosen and remove the bolts, a cumbersome and time-consuming process that not only significantly reduces replacement efficiency, becoming a bottleneck restricting the overall efficiency of the production line, but also increases the labor intensity of operators.

[0004] Furthermore, when one end of the take-up roll is disassembled, the entire weight of the roll and the heavy coil will be borne entirely by the bearing at the other end, creating a huge cantilever beam stress state. Forcibly pulling the coil off the roll in this state can easily cause the take-up roll to bend and deform, or damage the bearing structure at its support end, seriously affecting the service life and accuracy of the equipment.

[0005] Therefore, a winding device for woven bag production is needed to improve the above-mentioned problems. Utility Model Content

[0006] To address the problems of low disassembly efficiency of the winding rollers and easy equipment damage during unloading due to lack of effective support in the existing technology, this utility model provides a winding device for woven bag production to solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A winding device for woven bag production includes a winding mechanism. The winding mechanism has a support plate mechanism on its inner side, a pull cord linkage mechanism and two symmetrical slide rail mechanisms below the support plate mechanism, and a quick-release plate mechanism on one side of the winding mechanism, with a top block below the quick-release plate mechanism. The winding mechanism includes a base, side plates, a winding roller, and a tensioning assembly. The quick-release plate mechanism includes a support plate and a support half-frame fixedly connected above the support plate. A sliding plate is slidably connected to the inner side of the support half-frame, and a pull ring is fixedly connected to the inner side of the support plate. The slide rail mechanism includes a slide rail and a positioning plate inserted into one side of the slide rail. Two symmetrical toothed racks are provided on the inner side of the slide rail. The pull cord linkage mechanism includes an elastic pull cord, a connecting pull cord one, and a connecting pull cord two.

[0008] Preferably, the side plates are fixed above both sides of the base, and the winding roller is positioned between the two side plates, with one end of the winding roller rotatably connected to the side plates.

[0009] Preferably, the bottom of the support plate is connected to the base via a hinge, and a screw is rotatably connected to the top of the sliding plate, with the screw threaded through and connected to the support half-frame.

[0010] Preferably, the support plate has a groove on its upper part, a bottom arc plate is installed on the inner side of the groove, and a downward pressure arc plate is fixedly connected to the bottom of the sliding plate, with the downward pressure arc plate located inside the groove.

[0011] Preferably, the pallet mechanism includes an arc-shaped pallet and two symmetrical connecting rods at the lower ends of the arc-shaped pallet. Two symmetrical receiving sliders are slidably connected to the inner side of the slide rail. The upper ends of the connecting rods are rotatably connected to the arc-shaped pallet, and the lower ends of the connecting rods are drive-connected to the receiving sliders.

[0012] Preferably, the bottom of the receiving slider has a locking block that slides up and down, and a spring is set above the locking block. The locking block cooperates with the locking rack. One side of the positioning plate is fixedly connected with evenly arranged pull rings, and the other side of the positioning plate is fixedly connected with evenly arranged insert rods. The insert rods pass through the slide rail and are inserted into the receiving slider. A spring is set between the positioning plate and the slide rail.

[0013] Preferably, guide frame one and guide frame two are fixedly connected above the two slide rails respectively. Guide rods are rotatably connected to the inner sides of guide frame one and guide frame two. Connecting pull rope one and connecting pull rope two are symmetrical to each other and pass through the inner sides of guide frame one and guide frame two respectively.

[0014] Preferably, one end of the connecting pull rope one and the connecting pull rope two is connected to the pull ring two, and the other end of the connecting pull rope one and the connecting pull rope two are both fixedly connected to the elastic pull rope, and one end of the elastic pull rope is connected to the pull ring one.

[0015] The beneficial effects of this utility model are as follows: This utility model enables quick disassembly and installation of one end of the winding roller by setting up a quick-release plate mechanism and a top block structure, which improves the efficiency of changing woven bag rolls. After winding is completed, one end of the winding roller can be released simply by rotating the screw to move the sliding plate up, pulling out the top block and rotating the support plate. No bolts need to be removed, making the operation simple and quick.

[0016] This utility model, through the linkage design of the pallet mechanism and the slide rail mechanism, can automatically adjust the height of the arc-shaped pallet during the winding process to adapt to the increase in the diameter of the woven bag roll, maintain effective support for the roll material, prevent the roll material from deforming or loosening, and improve the winding quality.

[0017] This invention utilizes the coordinated action of a pull-cord linkage mechanism and a slide rail mechanism to automatically lock the position of the receiving slider while opening the quick-release plate, thereby fixing the height of the arc-shaped support plate. This ensures stable support when removing the woven bag roll, distributes the force on the winding roller, and extends the service life of the equipment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figure 1-6 The shown is a winding device for woven bag production, including a winding mechanism 1, a pallet mechanism 3 is provided on the inner side of the winding mechanism 1, a rope linkage mechanism 6 and two symmetrical slide rail mechanisms 4 are provided below the pallet mechanism 3, a quick release plate mechanism 2 is provided on one side of the winding mechanism 1, and a top block 5 is provided below the quick release plate mechanism 2. The winding mechanism 1 includes a base 11, a side plate 12, a winding roller 13, and a tensioning assembly 14; The quick-release plate mechanism 2 includes a support plate 21 and a support half-frame 22 fixedly connected above the support plate 21. A sliding plate 23 is slidably connected to the inner side of the support half-frame 22, and a pull ring 27 is fixedly connected to the inner side of the support plate 21. The slide rail mechanism 4 includes a slide rail 41 and a positioning plate 45 inserted into one side of the slide rail 41. Two symmetrical toothed racks 49 are provided on the inner side of the slide rail 41. The rope linkage mechanism 6 includes an elastic rope 61, a connecting rope one 62, and a connecting rope two 63.

[0022] The winding mechanism 1 constitutes a device for winding woven bags in the prior art, and a control device is provided on its outer side to control the operation of the entire device.

[0023] In this embodiment, the side plates 12 are fixed above both sides of the base 11, and the winding roller 13 is disposed between the two side plates 12, with one end of the winding roller 13 rotatably connected to the side plates 12. The tensioning assembly 14 is used to adjust the tension of the slit woven bag, and a motor is installed on one side of the side plate 12 to drive the winding roller 13 to rotate, thereby winding up the woven bag.

[0024] In this embodiment, the bottom of the support plate 21 is connected to the base 11 via a hinge, and the top of the sliding plate 23 is rotatably connected to a screw 24, which passes through and is threadedly connected to the support half-frame 22. One end of the top block 5 is an inclined surface, and its top can lift the support plate 21, thereby making the support plate 21 perpendicular to the base 11. At this time, the support plate 21 can support one end of the winding roller 13. The rotating sliding plate 23 can move the sliding plate 23 up and down with the pressing arc plate 25, thereby clamping one end of the winding roller 13.

[0025] In this embodiment, a groove is provided above the support plate 21, a bottom arc plate 26 is installed inside the groove, and a downward pressing arc plate 25 is fixedly connected to the bottom of the sliding plate 23. The downward pressing arc plate 25 is located inside the groove.

[0026] The lower pressure plate 25 and the bottom plate 26 are symmetrical, and both have ball bearings on their inner sides. Therefore, when one end of the winding roller 13 is located between the lower pressure plate 25 and the bottom plate 26, it can still rotate.

[0027] In this embodiment, the pallet mechanism 3 includes an arc-shaped pallet 31 and two symmetrical connecting rods 32 at the lower ends of the arc-shaped pallet 31. Two symmetrical receiving sliders 42 are slidably connected to the inner side of the slide rail 41. The upper ends of the connecting rods 32 are rotatably connected to the arc-shaped pallet 31, and the lower ends of the connecting rods 32 are drive-connected to the receiving sliders 42.

[0028] The surface of the arc-shaped pallet 31 is arc-shaped and smooth, which allows the woven bag to rotate during the winding process and push the woven bag along the direction of the arc-shaped pallet 31 during the unloading process.

[0029] In this embodiment, a locking block 43 slides up and down at the bottom of the receiving slider 42. A spring 44 is set above the locking block 43. The locking block 43 cooperates with the locking rack 49. A pull ring 47 is fixedly connected to one side of the positioning plate 45. A rod 46 is fixedly connected to the other side of the positioning plate 45. The rod 46 passes through the slide rail 41 and is inserted into the receiving slider 42. A spring 48 is set between the positioning plate 45 and the slide rail 41.

[0030] Spring 44 keeps the locking block 43 engaged with the locking rack 49, thereby supporting the upper arc-shaped support plate 31 via the connecting rod 32; the insert rod 46 can be inserted into one side of the receiving slider 42, thereby restricting the position of the receiving slider 42, thus preventing the arc-shaped support plate 31 from moving down via the connecting rod 32, thereby fixing the relative height of the arc-shaped support plate 31.

[0031] In this embodiment, guide frame 1 64 and guide frame 2 65 are fixedly connected above the two slide rails 41 respectively. Guide rods 66 are rotatably connected to the inner sides of guide frame 1 64 and guide frame 2 65. Connecting pull rope 1 62 and connecting pull rope 2 63 are symmetrical to each other and pass through the inner sides of guide frame 1 64 and guide frame 2 65 respectively.

[0032] Among them, connecting pull rope 1 62 and connecting pull rope 2 63 are used to apply tension evenly, so that the positioning plate 45 is close to the slide rail 41; guide frame 1 64 and guide frame 2 65 are used to change the direction of the tension; guide rod 66 is used to reduce the friction when connecting pull rope 1 62 and connecting pull rope 2 63 pass through, so as to avoid damage. Guide frame 1 64 and guide frame 2 65 are in the shape of a square frame, and guide rod 66 is rotatably connected to the inner side of the four sides of the square frame.

[0033] In this embodiment, one end of connecting pull rope 1 62 and connecting pull rope 2 63 is connected to pull ring 2 47, and the other end of connecting pull rope 1 62 and connecting pull rope 2 63 are both fixedly connected to elastic pull rope 61, and one end of elastic pull rope 61 is connected to pull ring 27.

[0034] Both the first connecting rope 62 and the second connecting rope 63 have three strands. The first connecting rope 62 faces the quick-release plate mechanism 2. One end of the second connecting rope 63 is connected to one end of the elastic rope 61, and one end of the first connecting rope 62 is connected to the left end of the elastic rope 61.

[0035] The working principle of this solution is as follows: After the woven bag is cut and tensioned by the tensioning component 14, it can be wound up by the winding roller 13. During the winding process, due to the continuous accumulation of the woven bag, it will expand outward, which will push the arc-shaped support plate 31 to move down, and through the connecting rod 32, the receiving slider 42 will slide, so that the displacement of the receiving slider 42 continues to support the height of the arc-shaped support plate 31. Once the outer perimeter of the winding roller 13 is fully wound, the sliding plate 23, along with the lower pressure arc plate 25, can be moved upward by rotating the screw 24, thereby releasing the pivot of the winding roller 13. Then, the top block 5 can be pulled out, causing the bottom of the support plate 21 to lose support. This allows the support plate 21 to rotate 90 degrees around the hinge base 11. At this point, the support plate 21 no longer supports one end of the winding roller 13, thus quickly releasing one end of the winding roller 13. This makes it convenient to remove the woven bag wound around the outer perimeter of the winding roller 13 without disassembling the bolts. Furthermore, when the support plate 21 is tilted and rotated 90 degrees, one end of the elastic pull rope 61 will be pulled by the pull ring 27. The connecting pull rope 63 at the other end of the elastic pull rope 61 and the connecting pull rope 62 in the middle will be guided by the guide frame 65 and the inner guide rod 66 of the guide frame 64 respectively, changing the direction of the pulling force. This will pull the positioning plate 45 and the insertion rod 46 towards one side of the slide rail 41 through the pull ring 47, so that the insertion rod 46 can be inserted and fixed in position of the receiving slider 42, thus preventing the receiving slider 42 from sliding. At this time, the height of the arc-shaped support plate 31 will also be determined by the connecting rod 32. Then, when picking up the woven bag on the outside of the winding roller 13, the arc-shaped support plate 31 can form an auxiliary support at the bottom, thereby distributing the weight and improving the service life of the winding roller 13 when one end of the winding roller 13 is not supported.

[0036] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
