Description

A winding unit, an ultrasonic slicing machine, and a roll of composite fiber textile fabric Technical Field

[0001] This utility model relates to the field of ultrasonic slicing machine technology, and more specifically, to a winding unit, an ultrasonic slicing machine, and a roll of composite fiber textile fabric. Background Technology

[0002] Tearable towels on the market have a heat-cut section that makes them easy to tear apart. The heat-cut section is easy to break under tension. When using them, only a little force is needed to break the heat-cut section, thereby tearing the two connected towels apart. The torn towels can be used individually. In the prior art, the heat-cut section of the towel is formed by transverse heat cutting of the whole towel using an ultrasonic heat-cutting device (such as an ultrasonic slicer). After heat cutting, the heat-cut towel is then rolled up on the outside of a roll (the roll is usually a paper tube) by a winding unit.

[0003] Some existing ultrasonic slicing machines have a winding unit consisting of a roller and a drive shaft. The drive shaft is driven to rotate by a motor or other device, and a roll is fitted around the outside of the roller. In order to smoothly wind up the towel, the diameter of the roller is generally set to be relatively large to increase the weight of the roller, so that the roller can press the towel more firmly onto the drive shaft when winding up the towel, thus ensuring that the wound towel is relatively tight and not loose. However, this structure also results in a large diameter of the roll fitted around the roller, resulting in a larger volume of towel products, larger packaging volume during transportation, and higher transportation costs. In addition, some existing winding units have a complex structure, making it difficult to disassemble and remove the roller, which is inconvenient for workers and affects production efficiency. Summary of the Invention

[0004] To address at least one of the aforementioned problems, this utility model provides a winding unit suitable for mounting on the frame of an ultrasonic slicer. The winding unit includes a roller, a drive shaft, a drive device, and a clamping frame. One end of the clamping frame is rotatably connected to the frame, and the roller is rotatably connected to the clamping frame. The roller includes a cylindrical shaft for mounting a roll, the diameter of which is 14mm-36mm. When winding material, the roll is mounted on the outside of the cylindrical shaft, and the end of the material to be wound is pressed against the roll and the drive shaft. The clamping frame uses its own weight to press the material against the drive shaft. The drive device drives the drive shaft to rotate, thereby winding the material onto the outside of the roll. This utility model has a simple structure and low production cost. By using the clamping frame to firmly press the material against the drive shaft, the diameter of the cylindrical shaft can be set to be smaller, thereby reducing the diameter of the roll, reducing the volume of the towel roll product, and lowering transportation costs.

[0005] Optionally, the material is a towel, and a rotating shaft is provided at the lower part of the pressing frame. The rotating shaft is rotatably connected to the frame, and a first bearing is provided between the rotating shaft and the frame. When the material is wound up, the pressing frame is in an inclined state. An angle is formed between the pressing frame and the horizontal plane, and the angle is 45°-80°.

[0006] Optionally, the clamping frame is provided with a mounting block for mounting the roller, and a second bearing is provided at both ends of the roller. The mounting block is provided with a mounting groove for detachably mounting the second bearing. When the roller is mounted on the mounting block, the second bearing is placed in the mounting groove, and the roller can rotate relative to the mounting block through the second bearing.

[0007] Optionally, the mounting groove is provided with an opening for inserting / removing the second bearing, and the opening is tilted downwards when the material is wound up.

[0008] Optionally, the second bearing is a bolt bearing, and the second bearing is threadedly connected to the roller.

[0009] Optionally, the roller further includes an inner shaft, and the cylindrical shaft includes a first cylindrical shaft and a second cylindrical shaft with the same diameter. The first cylindrical shaft and the second cylindrical shaft are both sleeved on the outside of the inner shaft. The drum is sleeved on the outside of both the first cylindrical shaft and the second cylindrical shaft. The first cylindrical shaft is provided with a first annular flange, and the second cylindrical shaft is provided with a second annular flange. A limiting installation groove is formed between the first annular flange and the second annular flange, and the drum is placed in the limiting installation groove for limiting.

[0010] Optionally, the axial length of the first cylindrical shaft is greater than the axial length of the second cylindrical shaft. The first cylindrical shaft is fixedly connected to the inner shaft, and the second cylindrical shaft is detachably connected to the inner shaft. The first cylindrical shaft is provided with a first bolt that is interference-fitted with the inner shaft, and the second cylindrical shaft is provided with a second bolt that is clearance-fitted with the inner shaft.

[0011] Optionally, the driving device is a motor, and the output end of the driving device is connected to the driving shaft; the diameter of the cylindrical shaft is 20mm-30mm.

[0012] Compared to existing technologies, the winding unit in this invention has a simple structure and low production cost. The pressing frame firmly presses the material against the drive shaft, allowing for a smaller diameter cylindrical shaft, which in turn reduces the diameter of the roll, decreases the volume of the towel roll, and lowers transportation costs. The mounting slot has an opening for inserting / removing the second bearing. When winding the material, the opening is tilted downwards, allowing the roller to press a portion of the material against the drive shaft using its own weight, resulting in a tighter roll of the towel. One end of the first bolt has a clearance fit with the inner shaft, facilitating the assembly and disassembly of the second cylindrical shaft. The second cylindrical shaft rotates synchronously with the inner shaft during assembly, and disassembly only requires slight axial sliding of the second cylindrical shaft. After removing the second cylindrical shaft, the rolled towel roll can be removed and a new roll to be rolled can be inserted. The shorter length of the second cylindrical shaft reduces operational difficulty and improves production efficiency.

[0013] In addition, this utility model also provides an ultrasonic slicing machine, which includes the above-mentioned winding unit. This ultrasonic slicing machine also has the beneficial effects of the above-mentioned winding unit, which will not be described in detail here.

[0014] In addition, this utility model also provides a roll of composite fiber textile fabric, which is produced by the ultrasonic slicing machine mentioned above. This roll of composite fiber textile fabric is small in size and saves transportation costs. Attached Figure Description

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0028] Referring to Figures 1-9, this embodiment of the present invention provides a winding unit suitable for mounting on the frame 1 of an ultrasonic slicer. The winding unit includes a roller 2, a drive shaft 3, a drive device 4, and a clamping frame 5. The clamping frame 5 is a rectangular frame, with one end rotatably connected to the frame 1. The roller 2 is rotatably connected to the clamping frame 5. The roller 2 includes a cylindrical shaft 21 for mounting a roll 6. The diameter of the cylindrical shaft 21 is 14mm-36mm, preferably 20mm-30mm. In this embodiment, the diameter of the cylindrical shaft 21 is 26mm. The diameter is appropriately sized to avoid increasing winding difficulty if the diameter is too small, and to avoid increasing product transport volume if the diameter is too large. The inner wall of the roll 6 is clearance-fitted with the cylindrical shaft 21, allowing the cylindrical shaft 21 to rotate synchronously with the roll 6, and the roll 6 can... The cylindrical shaft 21 can be disassembled. When winding the material, the drum 6 is fitted onto the outside of the cylindrical shaft 21, and the end of the material to be wound is placed between the drum 6 and the drive shaft 3. The clamping frame 5 presses a portion of the material against the drive shaft 3 by its own weight. The drive device 4 drives the drive shaft 3 to rotate, so as to wind the material onto the outside of the drum 6. During winding, the roller 2 rotates passively. The utility model has a simple structure and low production cost. By pressing the material tightly against the drive shaft by the clamping frame, the diameter of the cylindrical shaft can be set to be smaller, thereby reducing the diameter of the drum, reducing the volume of the towel roll product, and reducing transportation costs. During winding, in actual operation, the operator wraps the end of the material around the outside of the drum 6 once or approximately once to prevent the material from falling off at the beginning of winding, so as to ensure the smooth progress of the winding work.

[0029] Referring to Figure 1, the material is a towel 10, specifically a tearable towel. A rotating shaft 51 is provided at the lower part of the clamping frame 5. The rotating shaft 51 is rotatably connected to the frame 1. A first bearing 7 is provided between the rotating shaft 51 and the frame 1, which ensures smooth rotation and improves the smoothness of the material winding process. When winding the material, the clamping frame 5 is in an inclined state. The inclined clamping frame 5 can press a portion of the material that is against the roll 6 against the drive shaft 3 through the component of its own weight.

[0030] Referring to Figures 1, 2, and 4, when winding the material, the clamping frame 5 forms an angle A with the horizontal plane. The angle A is 45°-80°, and in this embodiment, the angle A is 55°-70°, specifically 63°. The size of the angle A is reasonably set. When the operator loads / unloads the roller 2, the clamping frame 5 needs to be flipped upwards. The angle A should not be set too small, so as not to make it too difficult for the operator to flip the clamping frame 5 upwards. The angle A should also not be set too large, so as not to make the wound towel product too loose due to poor pressing effect of the clamping frame 5.

[0031] Referring to Figures 1-3, the clamping frame 5 is equipped with a mounting block 52 for mounting the roller 2. Both ends of the roller 2 are equipped with second bearings 22. The mounting block 52 has a U-shaped mounting groove 521 for detachably mounting the second bearings 22. When the roller 2 is mounted on the mounting block 52, the second bearings 22 are placed in the mounting groove 521, allowing the roller 2 to rotate relative to the mounting block 52 smoothly, improving the stability of the winding process. After one towel product is wound up, the drive device 4 stops, tears apart the wound towel product from the towel material to be wound, flips the clamping frame 5 upwards, removes the roller 2 from the clamping frame 5, separates the towel product from the roller 2, and then reinstalls the roller 2 back into the clamping frame 5 to continue winding the next towel product. The operation is convenient. Referring to Figure 3, the arrows indicate the rotation direction of the roller 2 during winding.

[0032] Referring to Figures 2, 3, and 5, the mounting groove 521 is provided with an opening 522 for inserting / removing the second bearing 22. When the material is wound up, the opening 522 is tilted downwards so that the roller 2 can press a portion of the material against the roll 6 against the drive shaft 3 by its own weight, making the towel product wound more tightly. The second bearing 22 is a bolt bearing, which is threaded onto the roller 2. The structure is simple and the production cost is low.

[0033] Referring to Figures 2, 6, 7, 8, and 9, the roller 2 includes an inner shaft 23, and the cylindrical shaft 21 includes a first cylindrical shaft 211 and a second cylindrical shaft 212 of the same diameter. Both the first cylindrical shaft 211 and the second cylindrical shaft 212 are sleeved on the outside of the inner shaft 23. The drum 6 is sleeved on the outside of both the first cylindrical shaft 211 and the second cylindrical shaft 212. The first cylindrical shaft 211 is provided with a first annular flange 213, and the second cylindrical shaft 212 is provided with a second annular flange 214. A limiting mounting groove 215 is formed between the first annular flange 213 and the second annular flange 214. The drum 6 is placed in the limiting mounting groove 215 for limiting, and after limiting, the drum 6 is not easy to move, improving the stability during winding. The axial length of the first cylindrical shaft 211 is greater than the axial length of the second cylindrical shaft 212. The first cylindrical shaft 211 is fixedly connected to the inner shaft 23, and the second cylindrical shaft 212 is detachably connected to the inner shaft 23. The first cylindrical shaft 211 is provided with an interference fit with the inner shaft 23. A first bolt 242 is threaded to a first cylindrical shaft 211, and one end of the first bolt 242 has an interference fit with the inner shaft 23 to fix the first cylindrical shaft 211 to the inner shaft 23. A second bolt 252 is provided on the second cylindrical shaft 212, and the second bolt 252 is threaded to the second cylindrical shaft 212. One end of the first bolt 242 has an interference fit with the inner shaft 23 to fix the second cylindrical shaft 211 to the inner shaft 23. The second cylindrical shaft 212 is disassembled and assembled with the inner shaft 23. The second cylindrical shaft 212 rotates synchronously with the inner shaft 23 during assembly. When disassembling, only a slight force is needed to slide the second cylindrical shaft 212 axially. After removing the second cylindrical shaft 212, the roll 6 of the wound towel can be taken out and a new roll 6 of the towel to be wound can be installed. The operator can disassemble and assemble the shorter second cylindrical shaft 212, which reduces the difficulty of operation and improves production efficiency. If the part is disassembled and assembled, it will be inconvenient to operate because the part is relatively heavy and long.

[0034] Referring to Figure 1, the drive device 4 is a motor. The output end of the drive device 4 is connected to the drive shaft 3. The motor drives the drive shaft 3 to rotate / stop, which is convenient to control.

[0035] The winding unit in this invention has a simple structure and low production cost. The pressing frame firmly presses the material against the drive shaft, allowing for a smaller diameter cylindrical shaft, which in turn reduces the diameter of the roll, decreases the volume of the towel roll, and lowers transportation costs. The mounting slot has an opening for inserting / removing the second bearing. When winding the material, the opening is tilted downwards, allowing the roller to press a portion of the material against the drive shaft using its own weight, resulting in a tighter roll of the towel. One end of the first bolt has a clearance fit with the inner shaft, facilitating the assembly and disassembly of the second cylindrical shaft. The second cylindrical shaft rotates synchronously with the inner shaft during assembly, and disassembly only requires slight axial sliding of the second cylindrical shaft. After removing the second cylindrical shaft, the rolled towel roll can be removed and a new roll to be rolled can be inserted. The shorter length of the second cylindrical shaft reduces operational difficulty and improves production efficiency.

[0036] In addition, this utility model also provides an ultrasonic slicing machine, which includes the above-mentioned winding unit. This ultrasonic slicing machine also has the beneficial effects of the above-mentioned winding unit, which will not be described in detail here.

[0037] In addition, this utility model also provides a roll of composite fiber textile fabric, which is produced by the ultrasonic slicing machine mentioned above. This roll of composite fiber textile fabric is small in size and saves transportation costs.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
