Description

Technical Field

[0001] The invention relates to the technical field of container bag production, in particular to a winding device used for container bag production. Background Art

[0002] A bulk bag is a flexible transport packaging container, which is widely used in the transport packaging of powdered, granular and blocky items such as food, grains, medicines, chemicals and minerals. It is usually rolled into a tube during production for easy use.

[0003] For example, a container bag packaging and winding device with publication number CN221587441U winds the initial end of the container bag on the winding roller, starts the first cylinder to drive the bracket to move downward, so that the bottom ends of the two limit plates are close to the winding roller, starts the first motor to drive the screw to rotate, and the screw drives the two limit plates to move relative to each other, so that the two limit plates fit the two sides of the container bag, and starts the second motor to drive the winding roller to perform the winding operation, thereby achieving the purpose of limiting the two sides of the container bag and making it more neatly wound. However, in actual use, the container bag is woven by multiple layers of composite materials. In order to ensure the strength of the structure, the overall thickness of the container bag is approximately between 0.1 mm and 0.3 mm. When the container bag is being rolled up, the thickness of the container bag roll changes rapidly during the rolling process. The rolled container bag roll needs to be disassembled and replaced frequently, which is inconvenient. At present, a fixed structure is mostly used to position the roll. The disassembly and assembly process takes a long time, and the machine needs to be stopped during the disassembly and assembly process. The long downtime and low disassembly and assembly efficiency will affect the continuity of the container bag processing, reduce production efficiency, and have certain usage defects.

[0004] Therefore, we propose a winding device for container bag production to solve the above problems. Summary of the invention

At present, a fixed structure is mostly used to position the reel. The disassembly and assembly process takes a long time, and the machine needs to be stopped during the disassembly and assembly process.

The limiting plates are slidably connected with the rectangular grooves.

[0022] By adopting the above technical solution, the flexible intermediate bulk container is prevented from shifting during the winding movement, avoiding affecting the winding quality of the flexible intermediate bulk container.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: For the winding device used in the production of flexible intermediate bulk containers, a winding component is arranged on one side of the top of the workbench, so that the running of the rotating motor can fix the winding drum and wind the flexible intermediate bulk container. After the rotating motor stops running, the winding drum can automatically lose its limit, and then the winding drum can be directly removed after shutdown, which is convenient for the staff to disassemble the winding drum, reduces the shutdown time, is more convenient to operate, and improves the production continuity; 1. A winding component is provided on one side of the top of the workbench. When installing the reel, the reel is sleeved outside the two positioning plates. Then, the rotating motor is started. First, the rotating motor can drive the rotating plate to rotate. The connecting frame is inserted into the positioning hole, so that the movable plate will not rotate. The rotating plate rotates to push the two movable rods to move away from each other through the movable slot, so that the movable frame moves. The movable frame slides in the sliding slot for limiting. Furthermore, the two positioning plates can be made to move away from each other. After the positioning plates move, they drive the moving rods to slide on the mounting sleeve and stretch the telescopic springs. During the movement of the movable plate, the connecting frame can be driven to move. The two positioning plates are made of rubber. When the two positioning plates move and fit with the inner wall of the reel, they deform. At this time, the connecting frame just disengages from the positioning hole, so that the movable rod moves to the limit and abuts against the movable slot. Then, the two positioning plates can be driven to rotate by the rotating motor. The positioning plates fix the reel and then drive the reel to rotate, so that the flexible intermediate bulk container (FIBC) can be wound. During the winding process of the FIBC, the guide roller is driven to rotate. The damping bearing can provide resistance to the movement of the FIBC, which can assist the movable rod to abut against the movable slot. Furthermore, the FIBC is not likely to become loose during rotation, improving the winding quality. The rotating motor rotates to fix the reel. When the FIBC wound on the reel reaches a certain thickness, the operation of the rotating motor is stopped. Under the action of the telescopic spring, the positioning plates automatically reset. The output end of the rotating motor is not self-locking. Therefore, after the rotating motor stops running, the reel can be automatically released, and the reel sleeved outside the positioning plates will not fall off, preventing the reel from slipping and damaging the FIBC roll after losing its limit. Through the winding component, the rotating motor can be operated to fix the reel and wind the FIBC. After the rotating motor stops running, the reel can automatically lose its limit. Then, the reel can be directly removed after the machine stops, facilitating the staff to disassemble the reel, reducing the downtime, making the operation more convenient, and improving the production continuity; 2. The FIBC passes through the rotating roller and the movable roller during the winding process, and the FIBC drives the rotating roller and the movable roller to rotate during the winding process, which can further increase the resistance to the winding of the FIBC. During the winding process of the FIBC, overlapping folds may occur during its own movement (during normal conveying, the cross-section of the FIBC is rectangular, and when folds occur, the cross-section of the FIBC is similar to a wavy shape). If folds occur in the FIBC, its thickness will increase, causing the movable roller to tilt, so that the movable block slides on the fixed rod and compresses the return spring, driving the moving block to move upward, triggering the contact switch. Through the controller, the buzzer emits a sound, reminding the staff that an abnormal situation has occurred to the FIBC. The staff can stop the machine in time for adjustment, preventing the folds from being covered during direct winding and affecting the winding quality, improving the practicability; 3. During the winding process of the flexible intermediate bulk container (FIBC), the driving motor can be started to drive the bidirectional lead screw to rotate, so that the two movable seats can be driven to approach or move away from each other simultaneously. Furthermore, the two limiting plates can be driven to move. The two sides of the FIBC can be limited by the limiting plates, thereby avoiding the offset of the FIBC during the winding movement and preventing the influence on the winding quality of the FIBC, improving the practicability.

One side of the fixing plate 201 is fixedly installed with a mounting plate 202, and a rotating motor 203 is fixedly installed on the top of the mounting plate 202. The output end of the rotating motor 203 passes through the fixing plate 201 and is fixedly installed with a rotating plate 204. At the same time, two groups of movable slots 205 are symmetrically penetrated and connected on one side of the rotating plate 204, and two movable rods 206 are slidably connected inside the two groups of movable slots 205; A movable plate 207 is fixedly installed at one end of the movable rod 206. One end of the movable plate 207 away from the movable rod 206 is fixedly installed with a movable frame 208. Both ends of the two groups of movable frames 208 away from the movable rod 206 are fixedly installed with positioning plates 209. At the same time, a circular plate 210 is arranged on one side of the rotating plate 204. Two groups of sliding slots 211 are symmetrically penetrated and opened on one side of the circular plate 210, and the movable plate 207 is slidably connected with the sliding slots 211; An annular groove 212 is opened on the outside of the circular plate 210, and a limiting ring 213 is fixedly installed outside the circular plate 210 on the fixing plate 201, and the limiting ring 213 is slidably connected with the annular groove 212; A column rod 214 is fixedly installed at the center of one side of the circular plate 210 close to the positioning plate 209. A number of mounting slots 215 are opened on the outside of the column rod 214. Four mounting sleeves 216 are fixedly installed inside each group of four mounting slots 215. At the same time, a movable rod 218 is slidably connected inside the mounting sleeve 216, and one end of the movable rod 218 is fixedly connected with the positioning plate 209; One end of the movable rod 218 away from the positioning plate 209 is fixedly installed with a telescopic spring 217, and one end of the telescopic spring 217 away from the movable rod 218 is fixedly connected with the mounting slot 215; On one side of each of the group of movable plates 207, a connecting frame 219 is fixedly installed, and a positioning ring 220 is fixedly installed on one side of the fixed plate 201 where the rotating plate 204 is located. A number of positioning holes 221 are penetrated and opened on the outer side of the positioning ring 220. At the same time, the connecting frame 219 is adaptively connected to the positioning holes 221; On one side of the fixed plate 201 at the top of the workbench 1, fixing frames 102 are symmetrically installed, and a guide roller 103 is rotatably connected between the two fixing frames 102 through a damping bearing.

[0028] Example 1: As Figures 1-7As shown in the figure, a winding component 2 is arranged on one side of the top of the workbench 1. When installing the winding drum 101, the winding drum 101 is sleeved outside two positioning plates 209. Then, the rotation motor 203 is started. The rotation motor 203 can first drive the rotation plate 204 to rotate. The connecting frame 219 is inserted into the positioning hole 221, so that the movable plate 207 will not rotate. The rotation of the rotation plate 204 pushes the two movable rods 206 to move away from each other through the movable slot 205, so that the movable frame 208 moves. The movable frame 208 slides in the sliding slot 211 for limiting. Furthermore, the two positioning plates 209 can be made to move away from each other. After the positioning plates 209 move, they drive the moving rod 218 to slide on the mounting sleeve 216 and stretch the telescopic spring 217. During the movement of the movable plate 207, it can drive the connecting frame 219 to move. The two positioning plates 209 are made of rubber. When the two positioning plates 209 move and fit with the inner wall of the winding drum 101, they will deform. At this time, the connecting frame 219 just disengages from the positioning hole 221, so that the movable rod 206 moves to the limit and abuts against the movable slot 205. Then, the rotation motor 203 can drive the two positioning plates 209 to rotate, and the positioning plates 209 fix the winding drum 101 and then drive the winding drum 101 to rotate, so that the flexible intermediate bulk container can be wound. During the winding process of the flexible intermediate bulk container, it drives the guide roller 103 to rotate. The damping bearing can provide resistance to the movement of the flexible intermediate bulk container, which can assist the movable rod 206 to abut against the movable slot 205. Furthermore, the flexible intermediate bulk container is not easy to loosen during rotation, improving the winding quality. The rotation of the rotation motor 203 can fix the winding drum 101. When the flexible intermediate bulk container wound on the winding drum 101 reaches a certain thickness, the operation of the rotation motor 203 is stopped. Under the action of the telescopic spring 217, the positioning plates 209 automatically reset. The output end of the rotation motor 203 is not self-locking. Therefore, after the rotation motor 203 stops running, the winding drum 101 can be automatically released, and the winding drum 101 sleeved outside the positioning plates 209 will not fall off, avoiding the winding drum 101 from slipping and injuring the flexible intermediate bulk container roll after losing the limit. Through the winding component 2, the operation of the rotation motor 203 can fix the winding drum 101 and wind the flexible intermediate bulk container. After the rotation motor 203 stops running, the winding drum 101 can automatically lose the limit. Then, the winding drum 101 can be directly removed after shutdown, which is convenient for the staff to disassemble the winding drum 101, reduces the shutdown time, is more convenient to operate, and improves the production continuity.

[0029] A limiting component 3 is arranged on the other side of the top of the workbench 1; The limit component 3 includes a mounting frame 301 fixedly installed on the top of the workbench 1 on one side of the guide roller 103. The inner side of the mounting frame 301 is rotatably connected with a rotating roller 302 through a damping bearing. An active roller 303 is arranged above the rotating roller 302 on the inner side of the mounting frame 301. Both ends of the active roller 303 are rotatably connected with active blocks 304 through damping bearings. Symmetric through slots 305 are formed in the upper parts of both sides of the mounting frame 301. Fixed rods 306 are symmetrically installed inside the through slots 305. The active blocks 304 are slidably connected with the fixed rods 306. Above the outer parts of the two fixed rods 306, return springs 307 are sleeved. The two ends of the return springs 307 are fixedly connected with the through slots 305 and the active blocks 304 respectively; A support frame 309 is fixedly installed above the through slot 305 on one side of the mounting frame 301. A contact switch 310 is fixedly installed at the bottom end of the support frame 309. A moving block 308 is fixedly installed on one side of the active block 304. A buzzer 311 is fixedly installed above the support frame 309 on one side of the mounting frame 301. A controller 312 is arranged below the through slot 305 on one side of the mounting frame 301.

[0030] Embodiment 2: As Figure 1 and Figures 8-9 shown, the flexible intermediate bulk container passes through the rotating roller 302 and the active roller 303 during the winding process. During the winding process of the flexible intermediate bulk container, the rotating roller 302 and the active roller 303 are driven to rotate, which can further increase the resistance of the winding of the flexible intermediate bulk container. During the self - movement process of the flexible intermediate bulk container during the winding process, overlapping wrinkles may be generated. If wrinkles are generated on the flexible intermediate bulk container, the thickness will increase, which will cause the active roller 303 to tilt up, causing the active block 304 to slide on the fixed rod 306 and compress the return spring 307, thereby driving the moving block 308 to move upward, triggering the contact switch 310 by the upward movement of the moving block 308. The buzzer 311 emits a sound through the controller 312, so that the staff can be reminded that an abnormal situation occurs to the flexible intermediate bulk container. The staff can stop the machine in time for adjustment, avoiding the wrinkles being covered during direct winding, which affects the winding quality and improves the practicability.

[0031] Mounting blocks 313 are symmetrically installed on the top of the mounting frame 301. A bidirectional lead screw 314 is rotatably connected between the two mounting blocks 313. Movable seats 316 are symmetrically threadedly connected to the outer part of the bidirectional lead screw 314. A driving motor 315 is fixedly installed on one side of the right mounting block 313. The output end of the driving motor 315 passes through the right mounting block 313 and is fixedly connected with the bidirectional lead screw 314. Limit plates 317 are fixedly installed at the bottoms of the two movable seats 316. Rectangular slots 318 are symmetrically formed in the top of the mounting frame 301. The limit plates 317 are slidably connected with the rectangular slots 318.

[0032] Embodiment 3: AsFigure 1 and Figure 8 As shown, during the winding process of the flexible intermediate bulk container (FIBC), the driving motor 315 can be started to drive the bidirectional lead screw 314 to rotate, so that the two movable seats 316 can be driven to approach or move away from each other simultaneously. Furthermore, the two limit plates 317 can be driven to move. The two sides of the FIBC can be limited by the limit plates 317, thereby avoiding the deviation of the FIBC during the winding movement, preventing the influence on the winding quality of the FIBC, and improving the practicability.

[0033] Working principle: When using the winding device for FIBC production, first, as shown in Figures 1-9 , a winding assembly 2 is arranged on one side of the top of the workbench 1. When installing the winding drum 101, the winding drum 101 is sleeved outside the two groups of positioning plates 209. Then, the rotating motor 203 is started. The rotating motor 203 can first drive the rotating plate 204 to rotate. The connecting frame 219 is inserted into the positioning hole 221, so that the movable plate 207 will not rotate. The rotation of the rotating plate 204 pushes the two groups of movable rods 206 to move away from each other through the movable slot 205, so that the movable frame 208 moves. The movable frame 208 slides in the sliding slot 211 for positioning. Furthermore, the two groups of positioning plates 209 can be made to move away from each other. After the positioning plates 209 move, the moving rod 218 slides on the mounting sleeve 216 and stretches the telescopic spring 217. During the movement of the movable plate 207, the connecting frame 219 can be driven to move. The two groups of positioning plates 209 are made of rubber. When the two groups of positioning plates 209 move and fit with the inner wall of the winding drum 101, they deform. At this time, the connecting frame 219 just disengages from the positioning hole 221, so that the movable rod 206 moves to the limit and abuts against the movable slot 205. Then, the two groups of positioning plates 209 can be driven to rotate by the rotating motor 203. The positioning plates 209 fix the winding drum 101 and drive the winding drum 101 to rotate, so that the FIBC can be wound. During the winding process of the FIBC, the guide roller 103 is driven to rotate. The damping bearing can provide resistance to the movement of the FIBC, which can assist the movable rod 206 to abut against the movable slot 205. Furthermore, the FIBC is not easy to loosen during the rotation process, improving the winding quality. The rotation of the rotating motor 203 can fix the winding drum 101. When the FIBC wound on the winding drum 101 reaches a certain thickness, the operation of the rotating motor 203 is stopped. Under the action of the telescopic spring 217, the positioning plates 209 automatically reset. The output end of the rotating motor 203 is not self-locking. Therefore, after the rotating motor 203 stops running, the winding drum 101 can be automatically released, and the winding drum 101 sleeved outside the positioning plates 209 will not fall off, preventing the winding drum 101 from slipping and hurting the FIBC roll after losing the limit; During the winding process, the flexible intermediate bulk container passes through the rotating roller 302 and the movable roller 303, and the rotation of the rotating roller 302 and the movable roller 303 is driven during the winding process of the flexible intermediate bulk container, which can further increase the resistance of the winding of the flexible intermediate bulk container. During the movement of the flexible intermediate bulk container itself during the winding process, overlapping wrinkles may be generated. If wrinkles are generated on the flexible intermediate bulk container, the thickness will increase, which will cause the movable roller 303 to tilt, causing the movable block 304 to slide on the fixed rod 306 and compress the return spring 307, thereby driving the moving block 308 to move upward, causing the moving block 308 to move upward to trigger the contact switch 310, and causing the buzzer 311 to emit a sound through the controller 312, so as to remind the staff that an abnormal situation has occurred to the flexible intermediate bulk container, and the staff can stop the machine in time for adjustment. During the winding process of the flexible intermediate bulk container, the driving motor 315 can be started to drive the bidirectional lead screw 314 to rotate, so as to drive the two movable seats 316 to approach or move away from each other at the same time, and then drive the two limiting plates 317 to move. The two sides of the flexible intermediate bulk container can be limited through the limiting plates 317, so as to avoid the deviation of the flexible intermediate bulk container during the winding movement process, avoid affecting the winding quality of the flexible intermediate bulk container, and improve the practicability.
