Description

Technical Field

[0001] This utility model relates to the technical field of unwinding structure for a rewinding machine, specifically to an automatic rewinding machine for plastic woven bags. Background Technology

[0002] A winding machine is a device used to wind and store products. It is generally used on flexible products such as fabrics and woven bags. By rotating the winding column, the product can be wound into a cylindrical shape, making it easier to store or process for the next step.

[0003] Current winding machines typically remove the corresponding winding post along with the material during unwinding, and then place a new winding post on the machine for the next batch of winding. This method increases the weight of the woven bag roll because there is no support, and it may suddenly fall when the winding post is disassembled, which could easily lead to a safety accident. Therefore, an automatic winding machine for plastic woven bags is proposed. Utility Model Content

[0004] The technical problem this invention aims to solve is that current unwinding methods involve disassembling the winding post together, which increases the transport weight and, lacking auxiliary support, easily leads to safety accidents. This invention provides an automatic rewinding machine for plastic woven bags that separates the winding post from the woven bag roll, reducing its weight and providing auxiliary support to prevent safety accidents during disassembly.

[0005] The technical solution adopted by this utility model to solve the technical problem is: an automatic winding machine for plastic woven bags, including a support column, a rotating main shaft fixedly connected to the middle of the top of the support column, a connecting column rotatably connected to the top of the rotating main shaft, a motor detachably connected to the end of the connecting column away from the rotating main shaft, and a winding column detachably connected to the output end of the motor, a baffle fixedly connected to one end of the winding column, a movable horizontal plate provided on the side of the support column near the bottom, and lifting telescopic rods embedded and connected to both ends of the movable horizontal plate, with a support plate fixedly connected to the output end of the lifting telescopic rod.

[0006] As a preferred embodiment of this utility model, a movable telescopic rod is detachably embedded at one end of the movable horizontal plate near the support column, the output end of the movable telescopic rod is detachably connected to the side wall of the support column near the bottom, and three rollers are detachably connected evenly to the bottom side wall of the movable horizontal plate.

[0007] As a preferred embodiment of this utility model, the pallet has an L-shaped structure, the top of the vertical plate of the pallet has an arc-shaped structure with the same curvature as the winding column, the horizontal plate of the pallet has an arc-shaped structure corresponding to the woven bag winding column, and the height of the vertical plate of the pallet is the same as the radius of the woven bag winding column.

[0008] As a preferred technical solution of this utility model, a sliding groove is provided on one side wall of the baffle, and a slider is slidably connected in the sliding groove. A pressing plate is fixedly connected to one end of the slider. The curvature of the pressing plate is the same as that of the winding column. Auxiliary top columns are fixedly connected to the top of the support column and the two side walls near the rotating main shaft. A ball is rotatably connected to the top of the auxiliary top column, and the ball fits against the lower side wall of the connecting column.

[0009] As a preferred technical solution of this utility model, a stabilizing column is provided at the end of the winding column away from the baffle, and one end of the winding column is rotatably placed on the top of the stabilizing column. The stabilizing column is a telescopic structure, and an extension plate is fixedly connected to the same side of the stabilizing column and the supporting column. The extension plate is an inclined structure, and a tensioning column is rotatably connected to the end of the extension plate away from the supporting column.

[0010] This utility model has the following advantages: It is equipped with a lifting telescopic rod and a support plate, which provides auxiliary support for the woven bag roll, preventing it from suddenly falling during unwinding and causing safety accidents, thus improving production safety. The support plate can restrain the roll, and then moving the horizontal plate moves the support plate, thereby detaching the roll from the winding column. Simultaneously, because the vertical plate of the support plate has the same radius as the roll, and the curvature of the vertical plate fits the winding column, it can prevent the roll from being pulled apart during unwinding, ensuring the integrity of the roll after unwinding. Furthermore, it eliminates the need to disassemble the winding column, reducing the weight of the roll and improving transportation convenience. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to the following: Figure 1-3This utility model discloses an automatic winding machine for plastic woven bags, including a support column 1, a rotating main shaft 15 fixedly connected to the middle of the top of the support column 1, a connecting column 2 rotatably connected to the top of the rotating main shaft 15, a motor detachably connected to the end of the connecting column 2 away from the rotating main shaft 15, and a winding column 3 detachably connected to the output end of the motor, a baffle 4 fixedly connected to one end of the winding column 3, a movable horizontal plate 10 provided on the side of the support column 1 near the bottom, and lifting telescopic rods 11 embedded and connected to both ends of the movable horizontal plate 10, with a support plate 12 fixedly connected to the output end of the lifting telescopic rods 11.

[0017] A movable telescopic rod 17 is detachably connected to one end of the movable horizontal plate 10 near the support column 1. The output end of the movable telescopic rod 17 is detachably connected to the side wall of the support column 1 near the bottom. Three rollers 16 are detachably connected evenly to the bottom side wall of the movable horizontal plate 10. The support plate 12 has an L-shaped structure. The top of the vertical plate of the support plate 12 has an arc-shaped structure with the same curvature as the winding column 3. The horizontal plate of the support plate 12 has an arc-shaped structure corresponding to the woven bag rolling column. The height of the vertical plate of the support plate 12 is the same as the radius of the woven bag rolling column. A sliding groove 5 is opened on one side wall of the baffle 4. A slider 13 is slidably connected in the sliding groove 5. A pressing plate 6 is fixedly connected to one end of the slider 13. The curvature of the pressing plate 6 is the same as that of the winding column 3.

[0018] The technical effect of this solution is as follows: When unloading is required, the stabilizing column 7 is lowered, and then the winding column 3 is rotated to a state horizontal with the moving horizontal plate 10. The lifting telescopic rod 11 is activated in advance to raise the pallet 12 to a specified height. After the winding column 3 is rotated into place, the height of the pallet 12 is raised to support the winding column, ensuring the stability of the winding column 3 and the winding column, and avoiding safety accidents caused by sudden falls. After ensuring that the pallet 12 is in close contact with the winding column and the winding column 3, the moving horizontal plate 10 is driven to move horizontally by the moving telescopic rod 17, thereby removing the winding column from the winding column 3 without disassembling the winding column 3, reducing the weight after unloading and improving the convenience of transportation.

[0019] Auxiliary top columns 14 are fixedly connected to the top of the support column 1 and the two side walls near the rotating main shaft 15. The top of the auxiliary top column 14 is rotatably connected to a ball bearing, and the ball bearing is in contact with the lower side wall of the connecting column 2. A stabilizing column 7 is provided at the end of the winding column 3 away from the baffle 4. One end of the winding column 3 is rotatably placed on the top of the stabilizing column 7. The stabilizing column 7 is a telescopic structure. An extension plate 8 is fixedly connected to the same side of the stabilizing column 7 and the support column 1. The extension plate 8 is an inclined structure. A tensioning column 9 is rotatably connected to the end of the extension plate 8 away from the support column 1.

[0020] The technical effects of this solution are as follows: the rotating main shaft 15 ensures the smooth rotation of the connecting column 2, while the auxiliary top column 14 provides support for the connecting column 2, ensuring its stability and stability during rotation. The extension plate 8 and tensioning column 9 tighten the woven bag, ensuring the flatness of the winding and rolling, and preventing wrinkles from forming in the woven bag.

[0021] Specifically, in use, one end of the woven bag passes under the tensioning column 9 and is then pressed onto the winding column 3 by the pressing plate 6. The winding column 3 is then driven by a motor to rotate and wind the woven bag. When unwinding is required after winding, the stabilizing column 7 is lowered, and the winding column 3 is pushed to rotate along the rotating main shaft 15. At the same time, the lifting telescopic rod 11 is activated to raise the pallet 12 to a specified height, thereby supporting the winding column 3 and the roll, which are parallel to the moving horizontal plate 10, to ensure their stability. Then, the moving telescopic rod 17 is activated to push the moving horizontal plate 10 to move. The roll is detached from the winding column 3 by the restraint of the pallet 12. Thanks to the support of the pallet 12, the roll can be prevented from falling suddenly and causing a safety accident. Since it does not need to be disassembled and transported together with the winding column 3, the convenience of transportation is improved.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
