Description

Technical Field

[0001] This utility model relates to the field of ultrasonic slicing machine technology, specifically to a hot cutting 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 include an ultrasonic hot-cutting unit and a driving device. The hot-cutting unit includes a bottom mold and a moving mold (the moving mold is a roller cutter). The bottom mold is fixed and generates ultrasonic waves on its upper surface when energized. During processing, the towel to be hot-cut is placed between the bottom mold and the moving mold. The moving mold presses the towel firmly against the bottom mold. The driving device drives the moving mold to move laterally, thereby achieving lateral hot cutting to form the aforementioned hot-cut part. In the above-mentioned existing structure, because the bottom mold is fixed and the moving mold needs to cooperate with the bottom mold during hot cutting (that is, during hot cutting, the moving mold needs to always press the part of the towel to be hot-cut against the bottom mold), the length of the bottom mold needs to correspond to the width of the towel (the length of the bottom mold is generally greater than the width of the towel), resulting in a large volume of the bottom mold and high production and maintenance costs. In addition, after processing for a period of time, the bottom mold will be scratched by the moving mold (roller cutter), causing dents. These dents extend along the direction of the lateral displacement of the moving mold, causing a decrease in the hot-cut quality of the towel at the dents, requiring repair or replacement of the bottom mold, increasing costs. Utility Model Content

[0004] To address at least one of the aforementioned problems, this invention provides a hot-cutting unit suitable for installation on an ultrasonic slicer. The hot-cutting unit includes a frame, an ultrasonic base mold, and a cutter. The cutter is positioned on one side of the ultrasonic base mold. Both the ultrasonic base mold and the cutter are slidably mounted on the frame. A driving device is provided on the frame to drive the ultrasonic base mold and the cutter to slide in the same direction. The sliding speeds of the ultrasonic base mold and the cutter are the same or nearly the same. During hot-cutting, the material to be hot-cut is placed between the ultrasonic base mold and the cutter. The driving device drives the ultrasonic base mold and the cutter to slide synchronously. The side of the ultrasonic base mold closest to the material generates ultrasonic waves to perform ultrasonic hot-cutting on the material. The ultrasonic base mold of this invention can slide synchronously with the cutter, allowing for a smaller volume and lower production costs. The smaller ultrasonic base mold is also easier to disassemble, repair, or replace, reducing maintenance costs.

[0005] Optionally, the frame is provided with a first slide rail and a first sliding frame that slides with the first slide rail. The cutter is a roller cutter and is rotatably mounted on the first sliding frame. The driving device includes a first motor and a first transmission belt, and the first transmission belt is connected to the first sliding frame. During hot cutting, the first motor drives the first transmission belt to drive the first sliding frame and the cutter to slide.

[0006] Optionally, the first sliding frame includes a horizontal sliding frame and a vertical sliding frame. The horizontal sliding frame is slidably engaged with the first slide rail and connected to the first transmission belt. A cylinder is provided on the horizontal sliding frame, and the vertical sliding frame is connected to the telescopic rod of the cylinder. The cutter is rotatably mounted on the vertical sliding frame.

[0007] Optionally, a second motor for driving the cutter to rotate is provided on the vertical sliding frame.

[0008] Optionally, the frame is provided with a second slide rail and a second sliding frame that slides with the second slide rail. The ultrasonic bottom mold is connected to the second sliding frame. The driving device also includes a second transmission belt connected to the second sliding frame. During hot cutting, the first motor drives the second transmission belt to drive the second sliding frame and the ultrasonic bottom mold to slide.

[0009] Optionally, the material is a composite fiber textile fabric, and the ultrasonic bottom mold has an end face that generates ultrasonic waves. The end face is circular and has a diameter of 40mm-70mm.

[0010] Optionally, the ultrasonic base mold includes an ultrasonic transducer, a first mounting block, and a second mounting block. Both the first mounting block and the second mounting block are detachably mounted on the frame. The ultrasonic transducer has an outer flange arranged in annularly, and the outer flange is pressed between the first mounting block and the second mounting block for fixation.

[0011] Optionally, during hot cutting, the duration for which the cutter presses down and contacts the material is 1.2 seconds to 3.5 seconds.

[0012] Compared to existing technologies, the ultrasonic bottom mold in this invention's hot-cutting unit can slide synchronously with the cutter, allowing for a smaller ultrasonic bottom mold volume and lower production costs. The smaller ultrasonic bottom mold is easier to disassemble, repair, or replace, reducing maintenance costs. A single first motor drives the first and second sliding frames to slide synchronously, and the output shaft of the first motor is simultaneously connected to the first and second transmission belts, ensuring that the transmission speeds of the first and second transmission belts are the same, thus making the sliding speeds of the first and second sliding frames identical. This results in a rational structural design. The ultrasonic bottom mold can be disassembled... It is easy to install and disassemble. After disassembly, the upper surface of the ultrasonic transducer can be rotated circumferentially and repositioned. After repositioning, it can be repositioned so that the machining indentation on the end face can continue to be used in conjunction with the cutter for processing, thereby improving the utilization rate of the end face. When the end face can no longer be used after multiple repositionings, a new ultrasonic transducer can be replaced, reducing the replacement frequency and reducing costs. The hot cutting time is moderate so that the hot-cut parts of the material are processed, resulting in more stable hot-cut quality, smoother cut lines, and neater, cleaner, and flatter burrs after the material is torn apart, providing a better user experience.

[0013] In addition, this utility model also provides an ultrasonic slicer, which includes the above-mentioned hot cutting unit. This ultrasonic slicer also has the same beneficial effects as the above-mentioned hot cutting 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 aforementioned ultrasonic slicing machine. Due to the low production and maintenance costs of the aforementioned ultrasonic slicing machine, the manufacturing cost of this roll of composite fiber textile fabric is reduced. The roll of composite fiber textile fabric can be torn through the hot-cut section. The hot-cut (hot-melt) quality of this roll of composite fiber textile fabric is more stable, the cut line is more rounded, and after the fabric is torn, the rough edges are neater, cleaner, and flatter, resulting in a better user experience.

Detailed Implementation

[0023] 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.

[0024] 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.

[0025] 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.

[0026] See Figures 1-7This utility model provides a hot-cutting unit suitable for installation on an ultrasonic slicing machine. The hot-cutting unit includes a frame 1, an ultrasonic base mold 2, and a cutter 3. The cutter 3 is placed on one side of the ultrasonic base mold 2. Both the ultrasonic base mold 2 and the cutter 3 are slidably mounted on the frame 1. The frame 1 is equipped with a driving device for driving the ultrasonic base mold 2 and the cutter 3 to slide in the same direction. The sliding speeds of the ultrasonic base mold 2 and the cutter 3 are the same or tend to be the same, so that the ultrasonic base mold 2 and the cutter 3 can cooperate during hot-cutting processing. The cutting blade 3 always presses the material onto the ultrasonic base mold 2. During hot cutting, the material to be hot-cut is placed between the ultrasonic base mold 2 and the cutting blade 3. The driving device drives the ultrasonic base mold 2 and the cutting blade 3 to slide synchronously. The ultrasonic base mold 2 generates ultrasonic waves on the side closest to the material to perform ultrasonic hot cutting on the material. The ultrasonic base mold of this utility model can slide synchronously with the cutting blade, so that the volume of the ultrasonic base mold can be set to be small, resulting in low production cost. The small volume of the ultrasonic base mold is easy to disassemble, repair, or replace, reducing maintenance costs.

[0027] See Figure 1 , Figure 4 and Figure 5 The frame 1 is equipped with a first slide rail 11 and a first sliding frame 12 that slides smoothly with the first slide rail 11, improving the stability during processing. The cutter 3 is a roller cutter, which is rotatably mounted on the first sliding frame 12. The driving device includes a first motor 41 and a first transmission belt 42, which is connected to the first sliding frame 12 by bolts or other means. During hot cutting, the first motor 41 drives the first transmission belt 42 to drive the first sliding frame 12 and the cutter 3 to slide. The cutter 3 is driven to slide horizontally by the first motor 41 and the first transmission belt 42. The transmission structure is simple and reliable. The first motor 41 can be set as a speed-regulating motor, which can adjust the sliding speed of the cutter 3 according to the requirements, and has a wide range of applications.

[0028] See Figure 1 , Figure 4 , Figure 5 and Figure 6The first sliding frame 12 includes a horizontal sliding frame 121 and a vertical sliding frame 122. The horizontal sliding frame 121 is slidably engaged with the first slide rail 11 and connected to the first transmission belt 42. The first motor 41 synchronously drives the horizontal sliding frame 121 and the vertical sliding frame 122 to slide horizontally. A cylinder 5 is installed on the horizontal sliding frame 121, and the vertical sliding frame 122 is connected to the extension rod of the cylinder 5. The cutter 3 is rotatably mounted on the vertical sliding frame 122, and the height of the cutter 3 can be adjusted by the cylinder 5 to meet different hot cutting effects. For example, when the part to be processed by hot cutting is thin, the height of the cutter 3 can be lowered; the cylinder 5 can also be set as an electric cylinder; a second motor 123 for driving the cutter 3 to rotate is set on the vertical sliding frame 122. The second motor 123 can drive the cutter 3 to rotate circumferentially through a transmission belt, chain, etc. During hot cutting, the cutter 3 can make corresponding rotational movements, so that the resistance of the cutter 3 is smaller when sliding, the sliding is smoother, and the stability during processing is improved; the second motor 123 can be set as a speed-regulating motor so as to adjust the rotation speed of the cutter 3.

[0029] See Figure 1 and Figure 4 The frame 1 is equipped with a second slide rail 13 and a second sliding frame 14 that slides smoothly and stably with the second slide rail 13. The ultrasonic bottom mold 2 is connected to the second sliding frame 14 by bolts or other means. The driving device also includes a second transmission belt 43 connected to the second sliding frame 14. During hot cutting, the first motor 41 drives the second transmission belt 43 to drive the second sliding frame 14 and the ultrasonic bottom mold 2 to slide. The transmission structure is simple and reliable. The first sliding frame 12 and the second sliding frame 14 slide synchronously through the same first motor 41. The output shaft of the first motor 41 is connected to the first transmission belt 42 and the second transmission belt 43 at the same time, so that the transmission speed of the first transmission belt 42 and the second transmission belt 43 is the same, so that the sliding speed of the first sliding frame 12 and the second sliding frame 14 is the same. The structural design is reasonable.

[0030] See Figures 1-3 The material is a composite fiber textile fabric. The ultrasonic bottom mold 2 has an end face 202 that generates ultrasonic waves. The end face 202 is circular and the diameter L of the end face 202 is 40mm-70mm. In this embodiment, the diameter L is 54mm. The area of ​​the end face 202 is small, and the overall volume of the ultrasonic bottom mold 2 can be set to be small, so as to reduce production and maintenance costs.

[0031] See Figures 1-4The ultrasonic base mold 2 includes an ultrasonic transducer 20, a first mounting block 21, and a second mounting block 22. Both the first mounting block 21 and the second mounting block 22 are detachably mounted on the frame 1 using bolts. The ultrasonic base mold 2 is easy to assemble and disassemble. After disassembly, the upper end face of the ultrasonic transducer 20 can be rotated circumferentially and then reinstalled to reverse the machining indentation at the end face 202. This allows the intact portion of the end face 202 to continue processing with the cutting tool, improving the utilization rate of the end face 202. When the end face 202 becomes unusable after multiple reversals, a new ultrasonic transducer 20 is replaced, reducing the replacement frequency and cost. The ultrasonic transducer 20 has an annular outer flange 201, which is pressed between the first mounting block 21 and the second mounting block 22 for fixation. After installation, the structure is stable, improving processing stability. During the heat-cutting process, the duration for which the cutter 3 presses down and contacts the material is 1.2 to 3.5 seconds. This means the material completes one ultrasonic heat-cut in 1.2 to 3.5 seconds. The ultrasonic heat-cutting time refers to the duration for forming a complete tearable tangent (heat-cut section) on the material. The material is a tearable towel 6 that is torn through the aforementioned tangent (heat-cut section). In this embodiment, the heat-cutting time is 2.5 seconds. This moderate heat-cutting time ensures more stable heat-cutting (heat-melting) quality, a smoother tangent, and neater, cleaner, and flatter edges after tearing, resulting in a better user experience. The heat-cutting time should not be set too long, as this will slow down the process and affect efficiency. Conversely, the heat-cutting time should not be set too short, as this will result in poor heat-cutting (heat-melting) quality, leading to uneven and rough edges after tearing.

[0032] The hot-cutting unit of this invention features an ultrasonic bottom mold that slides synchronously with the cutter, allowing for a smaller ultrasonic bottom mold size and lower production costs. The smaller ultrasonic bottom mold is easy to disassemble, repair, or replace, reducing maintenance costs. A single first motor drives the first and second sliding frames to slide synchronously, with the output shaft of the first motor simultaneously connected to the first and second transmission belts, ensuring identical transmission speeds for both belts and the sliding frames. This design is rational. The ultrasonic bottom mold is easy to disassemble and assemble. After disassembly, the upper surface of the ultrasonic transducer can be rotated circumferentially and then reinstalled to reverse the machining indentation on the end face, allowing continued use of the intact portion of the end face in conjunction with the cutter, improving end face utilization. When the end face becomes unusable after multiple reversals, a new ultrasonic transducer is replaced, reducing replacement frequency and costs. The hot-cutting time is moderate, resulting in more stable hot-cut quality, smoother cut lines, and neater, cleaner, and flatter edges after tearing, providing a superior user experience.

[0033] In addition, this utility model also provides an ultrasonic slicer, which includes the above-mentioned hot cutting unit. This ultrasonic slicer also has the same beneficial effects as the above-mentioned hot cutting unit, which will not be described in detail here.

[0034] In addition, this utility model also provides a roll of composite fiber textile fabric, which is produced by the aforementioned ultrasonic slicing machine. Due to the low production and maintenance costs of the aforementioned ultrasonic slicing machine, the manufacturing cost of this roll of composite fiber textile fabric is reduced. The roll of composite fiber textile fabric can be torn through the hot-cut section. The hot-cut (hot-melt) quality of this roll of composite fiber textile fabric is more stable, the cut line is more rounded, and after the fabric is torn, the rough edges are neater, cleaner, and flatter, resulting in a better user experience.

[0035] 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.
