Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a webbing cutting device with an automatic debris cleaning function. Background Technology

[0002] Automatic webbing cutting machines, also known as fully automatic webbing cutting machines or fully automatic webbing shearing machines, are industrial cutting equipment mainly used for cutting webbing, nylon tape, elastic bands, and other materials to specific dimensions, serving ribbon factories, webbing factories, and the packaging and gift processing industry. The existing technology has the following problems:

[0003] Chinese patent document CN219547396U discloses a webbing equal-length cutting device. A rolling conveyor mechanism conveys the webbing to a guiding mechanism and a cutting mechanism. The guiding mechanism prevents the webbing from shifting during conveying. The cutting mechanism includes an upper cutting wheel and a lower cutting wheel. The upper and lower cutting wheels rotate synchronously but in opposite directions. A cutting component is mounted on the surface of the upper cutting wheel along its axial direction. A cutting groove corresponding to the cutting component is formed on the surface of the lower cutting wheel. Using this technical solution, the webbing enters the guiding mechanism and cutting mechanism under the conveying of the rolling conveyor mechanism. The guiding mechanism guides the webbing, preventing it from tilting. Once inside the cutting mechanism, the webbing, with one revolution of the upper cutting wheel, can be cut to the same length as its circumference. With the continuous rotation of the upper cutting wheel, the webbing can be quickly cut into several strips of equal length, greatly improving cutting efficiency.

[0004] Although the aforementioned literature allows for the cutting of webbing, the fiber debris generated during cutting tends to accumulate on the lower cutting roller or fall into the collection box along with the webbing. When it accumulates on the lower cutting roller or in the gaps, it can easily cause equipment jamming and accelerated wear. Operators need to frequently stop the machine to clean up the debris, reducing production efficiency and increasing labor costs. Furthermore, the debris that falls into the collection box requires an additional debris cleaning process due to the overlapping webbing, which is quite inconvenient. Utility Model Content

[0011] A further improvement of this utility model is that: the webbing guide mechanism includes an adjusting plate, which is fixedly installed on the top of two opposing plates. The adjusting plate has a vertically penetrating groove. A positive and negative threaded rod is movably installed on the right side of the inner wall of the groove. The left end of the positive and negative threaded rod extends through to the left side of the adjusting plate and is fixedly installed with a handwheel. The left and right sides of the outer wall of the positive and negative threaded rod are respectively provided with threaded walls with opposite threads, and the outer walls of the two threaded walls are threaded with adjusting hanging plates.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3As shown, this utility model provides a webbing cutting device with automatic debris cleaning function, including a debris cleaning mechanism 1, a webbing cutting mechanism 2 on the top of the debris cleaning mechanism 1, a fixed box 11, a limiting groove 12 on the rear side of the inner wall of the fixed box 11, support plates 13 fixedly installed on both the left and right sides of the inner wall of the fixed box 11, a pull hole 14 penetrating the inner cavity of the fixed box 11 on the front side, the top of the support plate 13 aligned with the bottom of the inner wall of the pull hole 14 and the limiting groove 12, a webbing collecting frame 15 engaged with the inner side of the pull hole 14 and the limiting groove 12, a stainless steel woven mesh 16 fixedly installed below the inner ring of the webbing collecting frame 15, and a rubber ring 17 fixedly fitted on the front side of the outer wall of the webbing collecting frame 15. Rubber ring 17 fits into the inner ring of pull hole 14. A debris collection drawer 18 is provided below the webbing collection frame 15. A vibration groove 111 is provided on the left side of the fixed box 11, which penetrates its inner cavity. A vibration contact plate 112 is fixedly installed on the right side of the inner ring of the vibration groove 111. The right side of the vibration contact plate 112 fits into the outer wall of the webbing collection frame 15. A vibration motor 113 is fixedly installed on the left side of the vibration contact plate 112. A second pull hole 114 is provided at the front end of the fixed box 11, which penetrates its inner cavity. The second pull hole 114 is located below the first pull hole 14. The front end of the debris collection drawer 18 is engaged with the inner ring of the second pull hole 114. A rubber ring 181 is fixedly fitted on the front side of the outer wall of the debris collection drawer 18. The rubber ring 181 fits into the inner ring of the second pull hole 114.

[0026] Since the conveyor wheel 24 is suspended above the fixed housing 11, the cut webbing along with the debris falls into the webbing collection frame 15 inside the fixed housing 11 and onto the stainless steel woven mesh 16. The webbing is collected by the stainless steel woven mesh 16, while the debris falls through the holes of the stainless steel woven mesh 16 into the debris collection drawer 18. To improve the efficiency of debris falling, the vibration motor 113 can be activated to control the webbing collection frame 15, which is in contact with the vibration contact plate 112, to vibrate at high frequency. This causes the webbing on the stainless steel woven mesh 16 to vibrate and constantly change position, allowing the debris to quickly fall through the stainless steel woven mesh 16, thus improving the screening and cleaning efficiency. When collecting the webbing, simply place the webbing collection frame 15... Simply pull it out from the inside of the pull-out hole 14. During installation, align it with the pull-out hole 14 and insert it. With the support of the support plate 13, slide it into the limiting slot 12 to complete placement. After insertion, the rubber ring 17 is inserted into the pull-out hole 14 to improve the stability of the webbing collection frame 15 and prevent it from falling off due to vibration. Similarly, when it is necessary to clean up the collected debris, simply pull out the debris collection drawer 18 located below the stainless steel woven mesh 16 inside the pull-out hole 214 to empty the debris. During installation, align the debris collection drawer 18 with the pull-out hole 214 and slide it in until the rubber ring 181 is inserted into the inner ring of the pull-out hole 214 to complete the fixation. This also prevents the debris collection drawer 18 from popping out due to vibration and ensures stability during the collection process.

[0027] like Figure 4 , Figure 5As shown, the webbing cutting mechanism 2 includes two L-shaped brackets 21. The bottom ends of the vertical parts of the two L-shaped brackets 21 are fixedly installed on the top left and right sides of the fixed housing 11, respectively. Opposing plates 22 are fixedly installed on the horizontal opposite ends of the two L-shaped brackets 21. Two servo motors 23 are fixedly installed on the front and rear sides of the left end of the left opposing plate 22. The output shafts of the servo motors 23 pass through the opposite surfaces of the two opposing plates 22 and are fixedly installed with conveyor wheels 24. A webbing guide mechanism 25 is provided in the middle of the opposite surfaces of the two opposing plates 22. The webbing guide mechanism 25 is located between the two front and rear conveyor wheels 24. The webbing guide mechanism 25 includes an adjusting plate 251, which is fixedly installed on the top of the two opposing plates 22. The adjusting plate 251 has a vertically penetrating groove. A positive and negative threaded rod 252 is movably installed on the right side of the inner wall of the chute. The left end of the positive and negative threaded rod 252 extends to the left side of the adjusting plate 251 and is fixedly installed with a handwheel 253. The left and right sides of the outer wall of the positive and negative threaded rod 252 are respectively provided with threaded walls with opposite threads, and the outer walls of the two threaded walls are threadedly installed with adjusting hanging plates 254. The two adjusting hanging plates 254 are slidably connected to the chute opened in the adjusting plate 251. The bottom ends of the two adjusting hanging plates 254 are fixedly installed with guide plates 255. The opposite surfaces of the two guide plates 255 are provided with pulley grooves 256. Several grooved pulleys 257 are movably installed between the upper and lower sides of the inner wall of the two pulley grooves 256. The groove of the grooved pulley 257 is on the same horizontal line as the top of the lower one of the two front and rear conveying wheels 24.

[0028] During cutting, four servo motors 23 are started synchronously. The encoder controls the rotation direction of the two lower servo motors 23 to be opposite to that of the upper servo motor 23, so that the webbing can be clamped between the upper and lower conveyor wheels 24 and conveyed forward. During the conveying process, the handwheel 253 can be rotated according to the width of the webbing, thereby driving the positive and negative threaded rods 252 to rotate. By using the threaded walls of the opposite threads on the left and right sides of the outer wall of the positive and negative threaded rods 252 to connect with the threads of the adjusting hanging plates 254, the guide plates 255 at the bottom of the two adjusting hanging plates 254 can be controlled to move closer to each other. At the same time, the grooved pulleys 257 in the pulley grooves 256 opened on the left and right guide plates 255 will also move closer to each other until they fit against both sides of the webbing, thereby limiting the left and right position of the webbing and preventing the webbing from shifting too much, which would affect the cutting effect. It can also improve the compatibility for webbing of different widths.

[0029] like Figure 6As shown, one of the upper two conveyor wheels 24 on the front side has a spring chamber 241. Several springs 242 are evenly fixedly installed on the inner wall of the spring chamber 241. A sliding plate 243 is fixedly installed on one end of the several springs 242 away from the center of the conveyor wheel 24. The sliding plate 243 is slidably connected to the inner cavity of the spring chamber 241. A cutting blade 244 is fixedly installed on the side of the sliding plate 243 away from the springs 242. The other end of the cutting blade 244 penetrates to the outer wall of the conveyor wheel 24.

[0030] When the webbing passes between the two front conveyor rollers 24, the cutting blade 244 protruding from the outer wall of the conveyor roller 24 will squeeze when it rotates between the lower conveyor roller 24, causing the slide plate 243 to compress the spring 242. Using the compression force of the spring 242 in the spring chamber 241, the cutting blade 244 can press the blade of the passing webbing to cut it, and achieve the same length of cutting of the webbing as it passes.

[0031] The working principle of this ribbon cutting device with automatic debris cleaning function will be explained in detail below.

[0032] like Figure 1-6As shown, during cutting, four servo motors 23 are started synchronously. An encoder controls the rotation direction of the two lower servo motors 23 to be opposite to that of the upper servo motor 23, thus clamping the webbing between the upper and lower conveyor wheels 24 and conveying it forward. During conveying, the handwheel 253 can be rotated according to the width of the webbing, thereby driving the positive and negative threaded rods 252 to rotate. The threaded walls of the positive and negative threaded rods 252, with their opposite threads on the left and right sides, are connected to the threads of the adjusting hanging plates 254, controlling the guide plates 255 at the bottom of the two adjusting hanging plates 254 to move closer together. Simultaneously, the grooved pulleys 257 in the pulley grooves 256 of the left and right guide plates 255 also move closer together until they fit against both sides of the webbing, thus cutting the webbing. The left and right positions are limited to prevent the webbing from shifting significantly and affecting the cutting effect. This also improves compatibility with webbing of different widths. When the webbing passes between the two front conveyor wheels 24, the protruding cutting blades 244 on the outer wall of the conveyor wheels 24 rotate to between the lower conveyor wheel 24, causing the slide plate 243 to compress the spring 242. Utilizing the compression force of the spring 242 within the spring chamber 241, the cutting blades 244 press against the passing webbing for cutting, achieving equal-length cuts as the webbing passes. Since the conveyor wheels 24 are suspended above the fixed housing 11, the cut webbing, along with debris, falls into the fixed housing 11. The webbing is collected inside the webbing collection frame 15 and falls onto the stainless steel woven mesh 16. The webbing is collected by the stainless steel woven mesh 16, while the debris falls through the holes of the stainless steel woven mesh 16 into the debris collection drawer 18. To improve the efficiency of debris falling, the webbing collection frame 15, which is in contact with the vibrating contact plate 112, is controlled to vibrate at high frequency by starting the vibration motor 113. This causes the webbing on the stainless steel woven mesh 16 to vibrate and constantly change position, allowing the debris to fall quickly through the stainless steel woven mesh 16, thus improving the screening and cleaning efficiency. When collecting the webbing, simply pull the webbing collection frame 15 out from the inside of the pull hole 14. During installation, align it with the stainless steel woven mesh 16. The tape collection frame 15 is inserted into the pull-out hole 14 and supported by the support plate 13 until it slides into the limiting slot 12 for placement. After insertion, the rubber ring 17 is inserted into the pull-out hole 14 to improve the stability of the tape collection frame 15 and prevent it from falling off due to vibration. Similarly, when it is necessary to clean up the collected debris, simply pull out the debris collection drawer 18 located under the stainless steel woven mesh 16 inside the pull-out hole 214 to empty the debris. During installation, align the debris collection drawer 18 with the pull-out hole 214 and slide it in until the rubber ring 181 is inserted into the inner ring of the pull-out hole 214 to complete the fixation. This also prevents the debris collection drawer 18 from popping out due to vibration and ensures stability during the collection process.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
