Description

Technical Field

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

[0002] A ton bag is a commonly used industrial packaging container for powder materials, usually weighing 1 ton. Currently, ton bags are available in various sizes, ranging from 0.5 to 3 tons. They are used for transporting powdery or granular materials, have a large loading capacity, and when full, their regular shape makes them easy to transfer and stack. They are widely used in the storage and handling of materials.

[0003] An existing patent (publication number: CN219193878U) discloses a ton bag winding mechanism, belonging to the field of ton bag production winding technology. It includes: a base plate for placing the entire winding mechanism; a mounting plate fixedly connected to the base plate, a fixed plate fixedly mounted on the mounting plate, a fixed roller rotatably connected to the mounting plate, and a movable roller slidably connected to the mounting plate. This invention solves the problem of wrinkles appearing after winding due to back-and-forth shaking during the ton bag winding process in the prior art. It limits the front-and-back position of the ton bag during winding, avoiding wrinkles caused by back-and-forth shaking, and effectively ensuring the neatness of the wound product.

[0004] Although the device in the aforementioned comparative document solves the problem of wrinkles appearing after winding due to back-and-forth shaking during the winding process of ton bags in the prior art, the device lacks compression and tension functions. When winding the ton bag fabric, it is easy to cause the ton bag fabric to be rolled unevenly, and the connection between the packing strap and the winding drum is relatively loose, resulting in the packing strap being loose on the winding drum. In order to solve the above problems, a winding device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a winding device with advantages such as pressing and tensioning functions, which solves the problems of uneven winding of fabric and loose connection between the packing strap and the winding drum when winding ton bag fabric.

[0006] To achieve the above objectives, this application provides the following technical solution: a winding device, including a base plate and a winding roller, wherein a vertical plate is fixedly connected to the top of the base plate, an L-shaped connecting plate is fixedly connected to the top of the vertical plate, and a shrinkage groove is provided inside the base plate;

[0007] The bottom of the L-shaped connecting plate is fixedly connected to multiple first elastic retractable rods. The bottom end of each first elastic retractable rod is fixedly connected to a first U-shaped plate. An extrusion rod is rotatably connected inside the first U-shaped plate. The top of the base plate is fixedly connected to a second U-shaped plate and a support frame. The top of the base plate is fixedly connected to a first electric push rod and two first retractable rods. The first electric push rod and the first retractable rods are located inside the second U-shaped plate, with one first electric push rod positioned between the two first retractable rods. The top ends of the first electric push rod and the first retractable rods are fixedly connected to a lower movable frame. Multiple lower rotating rods are rotatably connected inside the lower movable frame. The top end of the second U-shaped plate is fixedly connected to multiple second elastic retractable rods. The bottom end of each second elastic retractable rod is fixedly connected to an upper movable frame. Multiple upper rotating rods are rotatably connected inside the upper movable frame.

[0008] With the above scheme, by setting up a squeezing roller and a first elastic shrinking rod, when the fabric is being rolled up, the squeezing roller can constantly squeeze the fabric being rolled up on the surface of the rolling roller under the action of the first elastic shrinking rod, thereby improving the firmness of the fabric roll-up. By setting up a first electric push rod, the operation of the first electric push rod can push the lower rotating roller to move, thereby adjusting the distance between the lower rotating roller and the upper rotating roller, forming an upper and lower clamping mechanism to assist in material transmission and maintain tension, and to prevent the material from being too loose or too tight during the winding process.

[0009] Furthermore, a second electric push rod and two second retractable rods are fixedly connected to the top of the base plate. The second electric push rod and the second retractable rods are located inside the support frame, with one second electric push rod positioned between the two second retractable rods.

[0010] By implementing the above solution and installing a second electric push rod, the position of the tensioning roller can be adjusted.

[0011] Furthermore, a third U-shaped plate is fixedly connected to the top of the second electric push rod and the second retraction rod, and a tensioning rod is rotatably connected inside the third U-shaped plate.

[0012] By adjusting the position of the tensioning rollers, the tension of the fabric can be adjusted, ensuring that the fabric is rolled up evenly and tightly.

[0013] Furthermore, a rotating rod is tightly nested inside the upright plate via bearings. A second gear is fixedly connected to one end of the rotating rod. A rotary motor is fixedly connected to the side of the upright plate. A first gear is fixedly connected to the output end of the rotary motor. The first gear and the second gear mesh with each other. A fixed shell is fixedly connected to the side of the upright plate. The first gear and the second gear are located inside the fixed shell.

[0014] The above scheme involves setting up a rotary motor. When the rotary motor runs, it can rotate the first gear. Through the meshing of the first gear and the second gear, it can drive the rotating rod and the winding roller to rotate. The rotation of the winding roller can then be used to wind up the fabric.

[0015] Furthermore, a first connecting block is fixedly connected to the other end of the rotating rod, and a second connecting block is fixedly connected to one end of the winding roller. The second connecting block is snapped into the first connecting block, and two connecting bolts are threadedly connected inside the first and second connecting blocks.

[0016] The above solution, by setting the first connecting block and the second connecting block to interlock, facilitates quick replacement of the winding roller. The connecting bolts can be used to fasten the first connecting block and the second connecting block, ensuring that the winding roller and the rotating rod rotate synchronously.

[0017] Furthermore, a stepper motor is fixedly connected to the inner side of the shrinkage groove, a first threaded rod is fixedly connected to the output end of the stepper motor, a second threaded rod is fixedly connected to one end of the first threaded rod, the shaft end of the second threaded rod is rotatably connected to the inner side of the shrinkage groove, and threaded cylinders are threadedly connected to the surfaces of both the first and second threaded rods, with a movable plate fixedly connected to the surface of the threaded cylinder.

[0018] The above scheme, by setting a stepper motor, can rotate the first and second threaded rods. Through the limiting of the movable plate, the two threaded cylinders can be driven to move closer or further away from each other on the surfaces of the first and second threaded rods, thereby adjusting the distance between the two U-shaped limiting plates.

[0019] Furthermore, the movable plate is slidably connected within the shrinkage groove, and a U-shaped limiting plate is fixedly connected to the top of the movable plate, with the winding roller located inside the two U-shaped limiting plates.

[0020] The above solution, by setting a U-shaped limiting plate, can prevent the fabric from shifting when it is rolled up, thus limiting the fabric on both sides.

[0021] Furthermore, a limiting rod is rotatably connected inside the support frame.

[0022] The above solution, by setting a limiting rod, can guide the material path and prevent deviation.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This winding device, by setting up a squeezing roller and a first elastic shrinking rod, allows the squeezing roller to constantly compress the fabric on the surface of the winding roller during the winding process, thereby improving the firmness of the fabric winding. By setting up a first electric push rod, the operation of the first electric push rod can push the lower rotating roller to move, thereby adjusting the distance between the lower rotating roller and the upper rotating roller, forming an upper and lower clamping mechanism to assist in material transmission and maintain tension, preventing the material from being too loose or too tight during the winding process.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Please see Figure 1 , Figure 3 and Figure 4 The winding device in this embodiment includes a base plate 1 and a winding roller 2. A vertical plate 101 is fixedly connected to the top of the base plate 1, and an L-shaped connecting plate 102 is fixedly connected to the top of the vertical plate 101. A shrinkage groove 1032 is opened inside the base plate 1.

[0036] A plurality of first elastic retractable rods 103 are fixedly connected to the bottom of the L-shaped connecting plate 102. A first U-shaped plate 104 is fixedly connected to the bottom end of each first elastic retractable rod 103. A compression rod 105 is rotatably connected inside the first U-shaped plate 104. A second U-shaped plate 1018 and a support frame 1019 are fixedly connected to the top of the base plate 1. A first electric push rod 1021 and two first retractable rods 1023 are fixedly connected to the top of the base plate 1. The first electric push rod 1021 and the first retractable rods 1023 are located inside the second U-shaped plate 1018. One first electric push rod 1021 is located between two first retractable rods 1023. In section 23, a lower movable frame 1028 is fixedly connected to the top of the first electric push rod 1021 and the first shrinking rod 1023. Multiple lower rotating rollers 1029 are rotatably connected inside the lower movable frame 1028. Multiple second elastic shrinking rods 1027 are fixedly connected to the top of the inside of the second U-shaped plate 1018. An upper movable frame 1030 is fixedly connected to the bottom of the second elastic shrinking rods 1027. Multiple upper rotating rollers 1031 are rotatably connected inside the upper movable frame 1030. By setting the squeezing roller 105 and the first elastic shrinking rod 103, when the fabric is rolled up, the first elastic shrinking rod 103... Under the action of the compression roller 105, the fabric being wound on the surface of the winding roller 2 can be constantly compressed, thereby improving the firmness of the fabric winding. By setting the first electric push rod 1021, the operation of the first electric push rod 1021 can push the lower rotating roller 1029 to move, thereby adjusting the distance between the lower rotating roller 1029 and the upper rotating roller 1031, forming an upper and lower clamping mechanism to assist in material transmission and maintain tension, preventing the material from being too loose or too tight during the winding process. A second electric push rod 1022 and two second shrinking rods 1024 are fixedly connected to the top of the base plate 1. The second shrink rod 1022 and the second shrink rod 1024 are located inside the support frame 1019. A second electric push rod 1022 is located between the two second shrink rods 1024. By setting the second electric push rod 1022, the position of the tension rod 1026 can be adjusted. The top ends of the second electric push rod 1022 and the second shrink rod 1024 are fixedly connected to a third U-shaped plate 1025. The tension rod 1026 is rotatably connected inside the third U-shaped plate 1025. By adjusting the position of the tension rod 1026, the tension of the fabric can be adjusted, which can ensure that the fabric is rolled up evenly and tightly.

[0037] Please see Figure 5A rotating rod 109 is tightly nested inside the upright plate 101 via bearings. A second gear 1010 is fixedly connected to one end of the rotating rod 109. A rotary motor 107 is fixedly connected to the side of the upright plate 101. A first gear 108 is fixedly connected to the output end of the rotary motor 107. The first gear 108 and the second gear 1010 mesh with each other. A fixed housing 106 is fixedly connected to the side of the upright plate 101. The first gear 108 and the second gear 1010 are located within the fixed housing 106. When the rotary motor 107 operates, it causes the first gear 108 to rotate. Through the meshing of the first gear 108 and the second gear 1010, the rotating rod 109 is driven. The rotating rod 109 rotates with the take-up roller 2, which can take up the fabric. The other end of the rotating rod 109 is fixedly connected to the first connecting block 1011, and the other end of the take-up roller 2 is fixedly connected to the second connecting block 201. The second connecting block 201 is snapped into the first connecting block 1011. The first connecting block 1011 and the second connecting block 201 are internally threaded with two connecting bolts 3. By setting the snapping action of the first connecting block 1011 and the second connecting block 201, it is easy for people to quickly replace the take-up roller 2. By setting the connecting bolts 3, the first connecting block 1011 and the second connecting block 201 can be fastened to ensure that the take-up roller 2 and the rotating rod 109 rotate synchronously.

[0038] Please see Figure 3 A stepper motor 1012 is fixedly connected to the inner side of the shrinkage groove 1032. A first threaded rod 1013 is fixedly connected to the output end of the stepper motor 1012. A second threaded rod 1014 is fixedly connected to one end of the first threaded rod 1013. The shaft end of the second threaded rod 1014 is rotatably connected to the inner side of the shrinkage groove 1032. Threaded cylinders 1015 are threadedly connected to the surfaces of both the first threaded rod 1013 and the second threaded rod 1014. A movable plate 1016 is fixedly connected to the surface of the threaded cylinder 1015. By setting the stepper motor 1012, when the stepper motor 1012 runs, the first threaded rod 1013 and the second threaded rod 1014 can be rotated. 014 rotates, and through the limiting of the movable plate 1016, it can drive the two threaded cylinders 1015 to move closer or further away from each other on the surfaces of the first threaded rod 1013 and the second threaded rod 1014, thereby adjusting the distance between the two U-shaped limiting plates 1017. The movable plate 1016 is slidably connected in the shrink groove 1032, and the top of the movable plate 1016 is fixedly connected to the U-shaped limiting plate 1017. The winding roller 2 is located inside the two U-shaped limiting plates 1017. By setting the U-shaped limiting plates 1017, the fabric can be prevented from shifting when winding, thereby limiting the two sides of the fabric.

[0039] Please see Figure 4 The support frame 1019 has a rotatable connection to a limiting rod 1020. By setting the limiting rod 1020, the material path can be guided and deviation can be prevented.

[0040] In this embodiment, by setting up a squeezing roller 105 and a first elastic shrinking rod 103, when the fabric is being rolled up, the squeezing roller 105 can constantly squeeze the fabric being rolled up on the surface of the winding roller 2 under the action of the first elastic shrinking rod 103, thereby improving the firmness of the fabric roll-up. By setting up a first electric push rod 1021, the operation of the first electric push rod 1021 can push the lower rotating roller 1029 to move, thereby adjusting the distance between the lower rotating roller 1029 and the upper rotating roller 1031, forming an upper and lower clamping mechanism to assist in material transmission and maintain tension, preventing the material from being too loose or too tight during the winding process. By setting up a second electric push rod 1022 and a tensioning roller 1026, the operation of the second electric push rod 1022 can adjust the position of the tensioning roller 1026. By adjusting the position of the tensioning roller 1026, the tension of the fabric can be adjusted, ensuring that the fabric is rolled up evenly and tightly.

[0041] The working principle of the above embodiment is as follows: In use, the second connecting block 201 is snapped into the first connecting block 1011, and then the first connecting block 1011 and the second connecting block 201 are connected by two connecting bolts 3. After the connection is completed, the fabric is passed through the surface of the limiting roller 1020 and the tensioning roller 1026, and then through the support of the lower rotating roller 1029 and the upper rotating roller 1031, and finally wound around the surface of the winding roller 2. After the winding is completed, the rotary motor 107 is started to make the first gear 108 rotate. Through the meshing of the first gear 108 and the second gear 1010, the fabric can be wound around the surface of the winding roller 2. The rotating rod 109 and the winding roller 2 are rotated. The rotation of the winding roller 2 can wind up the fabric. During winding, the stepper motor 1012 runs, which can rotate the first threaded rod 1013 and the second threaded rod 1014. Then, through the limiting of the movable plate 1016, the two threaded cylinders 1015 can be driven to move closer or further away from each other on the surfaces of the first threaded rod 1013 and the second threaded rod 1014, thereby adjusting the distance between the two U-shaped limiting plates 1017. When winding up the fabric, it can prevent the fabric from deviating, thus limiting the two sides of the fabric.

[0042] By setting up the extrusion roller 105 and the first elastic shrinking rod 103, when the fabric is being rolled up, the extrusion roller 105 can constantly squeeze the fabric being rolled up on the surface of the rolling roller 2 under the action of the first elastic shrinking rod 103, thereby improving the firmness of the fabric roll-up.

[0043] By setting a second electric push rod 1022 and a tensioning roller 1026, the operation of the second electric push rod 1022 can adjust the position of the tensioning roller 1026, thereby adjusting the tension of the fabric and ensuring that the fabric is wound evenly and tightly. By setting a first electric push rod 1021, the operation of the first electric push rod 1021 can push the lower rotating roller 1029 to move, thereby adjusting the distance between the lower rotating roller 1029 and the upper rotating roller 1031, forming an upper and lower clamping mechanism to assist in material transmission and maintain tension, and prevent the material from being too loose or too tight during the winding process.
