Description

Technical Field

[0001] This utility model relates to the field of weed control fabric production technology, specifically a rewinding machine for weed control fabric production. Background Technology

[0002] In the production and processing of weed control fabric, rewinding is a crucial post-processing step. Its core function is to rewind the produced continuous weed control fabric rolls into finished rolls with uniform specifications and tight structure according to the needs of subsequent storage, transportation and use. This directly affects the final quality and ease of use of the weed control fabric. However, the conventional weed control fabric rewinding equipment currently on the market still has many problems that need to be solved in actual application, making it difficult to meet the needs of efficient and high-quality production.

[0003] The design of the winding and unwinding mechanisms in existing rewinding equipment has flaws. The fixing and disassembly of the winding and unwinding rollers are complicated and cumbersome. Most equipment adopts an integrated or multi-bolt fastening structure. When changing to different specifications of winding rollers or removing the finished roll after completing the rewinding operation, a lot of time is required to disassemble and assemble the parts. This not only prolongs the auxiliary time of a single operation and reduces the overall production efficiency, but also increases the labor intensity of the operators.

[0004] According to the patent application published on the Internet, a storage and winding device for producing weed control fabric (authorization announcement number: CN216105050U) is described as including a "base, support plate" etc., to realize the winding work.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This device for storing and winding weed control fabric uses a base and support plate to achieve the winding operation. When in use, the device uses an electric winding roller for winding. However, after winding, it cannot be easily disassembled, which affects the winding operation. Therefore, this device needs to be improved. Utility Model Content

[0007] The purpose of this utility model is to provide a rewinding machine for producing weed control fabric, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a rewinding machine for producing weed control fabric, comprising a base, rewinding mechanisms on the left and right sides of the top of the base, and a tension adjustment mechanism on the top of the base;

[0009] The rewinding mechanism includes a support plate, which is fixedly connected to the top right side of the base. A fixed frame is fixedly connected to the rear side of the support plate, and a hydraulic cylinder is fixedly connected to the rear side of the fixed frame. A fixed plate is fixedly connected to the front side of the hydraulic cylinder, and a first servo motor is fixedly connected to the rear side of the fixed plate. A rotating rod is fixedly connected to the front side of the first servo motor, and a connecting shaft is fixedly connected to the front side of the rotating rod. A support roller is inserted into the outer periphery of the front end of the connecting shaft. A limit plate is threadedly connected to the outer periphery of the support roller. A support cylinder is slidably connected to the outer periphery of the front end of the support roller. A connecting arm is fixedly connected to the front side of the support cylinder. A support column is slidably connected to the outer periphery of the right end of the connecting arm. A fixed shaft is threadedly connected inside the connecting arm, and a load-bearing frame is fixedly connected to the left side of the bottom of the connecting arm.

[0010] Preferably, the fixed plate is slidably connected to the fixed frame, and the rotating rod is rotatably connected to the inside of the fixed plate, so as to facilitate the rotation of the connecting shaft by the rotating rod.

[0011] Preferably, the fixed shaft passes through the inside of the support column, and the support column is fixedly connected to the right side of the base, so as to ensure the stability between the connecting arm and the support column through the fixed shaft.

[0012] Preferably, the load-bearing frame is slidably connected to the inside of the base, and two sets of limiting plates are provided, which are symmetrically distributed on the front and rear sides of the outer periphery of the support roller, so as to fix the take-up roller on the support roller through the limiting plates.

[0013] Preferably, the support plate, support roller, support cylinder, limiting plate, connecting arm, support column, fixed shaft and load-bearing frame are provided in two sets and symmetrically distributed on the left and right sides of the top of the base. The right side is for taking in the fabric and the left side is for putting in the fabric. By setting two sets, the fabric can be put in and taken in at the same time.

[0014] Preferably, the tension adjustment mechanism includes a concave frame, which is fixedly connected to the top of the base. A second servo motor is fixedly connected to the front side of the concave frame, and a rotating shaft is fixedly connected to the rear side of the second servo motor. The rotating shaft is rotatably connected inside the concave frame, and a connecting frame is fixedly connected to the periphery of the rotating shaft. A connecting rod is fixedly connected to the inner side of the connecting frame, and a pressing roller is rotatably connected to the periphery of the connecting rod.

[0015] Preferably, the pressing roller is located between two sets of support rollers, which facilitates pressing the weed control fabric with the pressing roller and ensures neatness during the rewinding process.

[0016] Compared with the prior art, this utility model provides a rewinding machine for producing weed control fabric, which has the following beneficial effects:

[0017] 1. This rewinding machine for weed control fabric production, through its rewinding mechanism, allows for the following steps during weed control fabric production: First, the take-up roller is slid to the outer periphery of the support roller and positioned in the middle. Two sets of limiting discs are rotated to fix the take-up roller, ensuring its stability. Simultaneously, the connecting arm is slid into the support column, driving the support cylinder to slide to the outer periphery of the support roller's front end. This allows the load-bearing frame to slide into the base. The fixed shaft secures the support column and connecting arm, ensuring the stability of the support cylinder and support roller. Two sets of components—support plate, support roller, support cylinder, limiting disc, connecting arm, support column, fixed shaft, and load-bearing frame—are provided, allowing for simultaneous fixing of the take-up and unload rollers, thus improving ease of installation and disassembly. During rewinding, the hydraulic cylinder pushes the fixed plate to slide within the fixed frame, causing the servo motor to drive the rotating rod and connecting shaft to insert into the support roller on the right side, rotating the take-up roller for rewinding.

[0018] 2. This rewinding machine for producing weed control fabric, through a tension adjustment mechanism, has a concave frame fixed on top of the base, with the pressing roller located between two sets of support rollers, adapted to the transmission path of the weed control fabric. During operation, the second servo motor drives the rotating shaft to rotate within the concave frame. The rotating shaft drives the connecting frame and connecting rod to rotate synchronously, thereby adjusting the pressing pressure of the pressing roller on the weed control fabric. When the tension of the weed control fabric is too low, the pressure of the pressing roller can be increased to raise the tension, preventing the weed control fabric from loosening and causing loose rewinding. When the tension of the weed control fabric is too high, the pressure of the pressing roller can be reduced to lower the tension, preventing the weed control fabric from being damaged or deformed due to excessive stretching. This ensures that the weed control fabric maintains a uniform and appropriate tension throughout the rewinding process, resulting in a tightly wound weed control fabric. Attached Figure Description

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-6 This utility model provides a technical solution: a rewinding machine for producing weed control fabric, including a base 1, rewinding mechanisms 2 are provided on the left and right sides of the top of the base 1, and a tension adjustment mechanism 3 is provided on the top of the base 1;

[0032] The rewinding mechanism 2 includes a support plate 21, which is fixedly connected to the top right side of the base 1. A fixed frame 22 is fixedly connected to the rear side of the support plate 21. A hydraulic cylinder 23 is fixedly connected to the rear side of the fixed frame 22. A fixed plate 25 is fixedly connected to the front side of the hydraulic cylinder 23. A first servo motor 24 is fixedly connected to the rear side of the fixed plate 25. A rotating rod 28 is fixedly connected to the front side of the first servo motor 24. A connecting shaft 29 is fixedly connected to the front side of the rotating rod 28. A support roller 26 is inserted into the outer periphery of the front end of the connecting shaft 29. A limit plate 291 is threadedly connected to the outer periphery of the outer periphery of the support roller 26. A support cylinder 27 is slidably connected to the outer periphery of the front end of the support roller 26. A connecting arm 292 is fixedly connected to the front side of the support cylinder 27. A support column 293 is slidably connected to the outer periphery of the right end of the connecting arm 292. A fixed shaft 294 is threadedly connected inside the connecting arm 292. A load-bearing frame 295 is fixedly connected to the left side of the bottom of the connecting arm 292.

[0033] The fixed plate 25 is slidably connected to the fixed frame 22, and the rotating rod 28 is rotatably connected to the inside of the fixed plate 25, so that the connecting shaft 29 can be rotated through the rotating rod 28.

[0034] The fixed shaft 294 passes through the inside of the support column 293, which is fixedly connected to the right side of the base 1, so as to ensure the stability between the connecting arm 292 and the support column 293 through the fixed shaft 294.

[0035] The load-bearing frame 295 is slidably connected to the inside of the base 1. Two sets of limiting plates 291 are provided and symmetrically distributed on the front and rear sides of the outer periphery of the support roller 26, so as to fix the take-up roller on the support roller 26 through the limiting plates 291.

[0036] The support plate 21, support roller 26, support cylinder 27, limiting plate 291, connecting arm 292, support column 293, fixed shaft 294 and load-bearing frame 295 are provided in two sets and are symmetrically distributed on the left and right sides of the top of the base 1. The right side is for taking in the fabric and the left side is for putting in the fabric. By setting two sets, the fabric can be put in and taken in separately.

[0037] Example 2

[0038] Please see Figure 1-6 Furthermore, based on Embodiment 1, the tension adjustment mechanism 3 further includes a concave frame 31, which is fixedly connected to the top of the base 1. A second servo motor 32 is fixedly connected to the front side of the concave frame 31, and a rotating shaft 33 is fixedly connected to the rear side of the second servo motor 32. The rotating shaft 33 is rotatably connected to the inside of the concave frame 31, and a connecting frame 34 is fixedly connected to the periphery of the rotating shaft 33. A connecting rod 35 is fixedly connected to the inner side of the connecting frame 34, and a pressing roller 36 is rotatably connected to the periphery of the connecting rod 35.

[0039] The pressing roller 36 is located between the two sets of support rollers 26, which facilitates pressing the weed control fabric through the pressing roller 36 to ensure neatness during the rewinding process.

[0040] In actual operation, when this device is used and rewinding is required during the production of weed control fabric, the take-up roller for weed control fabric is first slid to the outer periphery of the support roller 26 and positioned in the middle of the support roller 26. The two sets of limiting discs 291 are rotated to fix the take-up roller under the action of the limiting discs 291, ensuring its stability. At the same time, the connecting arm 292 is slid into the support column 293, which in turn drives the support cylinder 27 to slide to the outer periphery of the front end of the support roller 26, so that the load-bearing frame 295 slides into the base 1. The support column 293 and the connecting arm 292 are fixed by the fixing shaft 294, which can ensure the stability of the support cylinder 27 and the support roller 26. The support plate 21, support roller 26, support cylinder 27, limiting disc 291, connecting arm 292, support column 293, fixing shaft 294 and load-bearing frame 295 are provided in two sets, which can fix the take-up roller and the release roller at the same time, thereby improving the convenience of installation and disassembly.

[0041] During rewinding, hydraulic cylinder 23 pushes fixed plate 25 to slide within fixed frame 22, thereby causing servo motor to drive rotating rod 28 and connecting shaft 29 to insert into the support rollers 26 on the right side, driving take-up roller to rotate for rewinding. Concave frame 31 is fixed to the top of base 1, and pressing roller 36 is located between the two sets of support rollers 26, adapted to the transmission path of weed control fabric. During operation, second servo motor 32 drives rotating shaft 33 to rotate within concave frame 31, and rotating shaft 33 drives connecting frame 34. The connecting rod 35 rotates synchronously, thereby adjusting the pressing pressure of the pressing roller 36 on the weed control fabric. When the tension of the weed control fabric is too low, the pressure of the pressing roller 36 can be increased to raise the tension, thus preventing the weed control fabric from loosening and causing loose rewinding. When the tension of the weed control fabric is too high, the pressure of the pressing roller 36 can be reduced to lower the tension, preventing the weed control fabric from being damaged or deformed due to excessive stretching. This ensures that the weed control fabric maintains a uniform and appropriate tension throughout the rewinding process, resulting in a tightly rolled weed control fabric.
