Description

Technical Field

[0001] The present invention belongs to the technical field of zipper detection, and particularly relates to a detection device for preventing missing teeth of special-shaped zipper teeth. Background Art

[0002] A zipper is a connecting piece that relies on continuously arranged zipper teeth to join or separate items, and is widely used in clothing, bags, tents, etc. Missing teeth refer to the phenomenon that a certain zipper tooth is missing on the continuous zipper teeth. When directly used, it will cause certain adverse effects, so it is necessary to detect the missing teeth of the zipper tape to avoid affecting subsequent production.

[0003] In the prior art, a Chinese patent with the patent number CN204353116U discloses a detection device for preventing missing teeth of a zipper, including a frame, a conveying device, a detection device and a marking device. The conveying device, the detection device and the marking device are sequentially installed on the frame along the feeding direction. The frame includes a horizontally arranged mounting plate, a vertically arranged adjusting frame and a plurality of sliding rollers. The conveying device, the detection device and the sliding rollers are installed on the side surface of the mounting plate. The sliding rollers are arranged side by side and are located below the detection device. The zipper passes through the conveying device and is fed horizontally on the sliding rollers. The adjusting frame is located between the two sliding rollers, and there is a certain horizontal distance between the adjusting frame and the side surface of the mounting plate. When the detection device detects the position of missing teeth on the cloth strip, the marking device marks the position of missing teeth on the cloth strip detected by the detection device, which is convenient for workers to find the position of missing teeth on the zipper, ensures the qualification rate of products and reduces the workload of staff.

[0004] In the prior art, by using a detection device to detect the position of missing teeth on the zipper and marking at the corresponding position through a marking device, it is convenient to find the position of missing teeth on the zipper and ensure the qualification rate of products. However, there are still certain deficiencies in the overall use: First, although the above prior art can detect and punch missing teeth of the zipper, it can only detect missing teeth and cannot comprehensively identify the quality problems of the zipper teeth, such as the length of the zipper teeth and the biting force between the zipper teeth, which reduces the accuracy of the detection results and cannot improve the quality of the zippers produced subsequently.

[0005] Secondly, after a complete zipper is produced, the overall cloth tape of the zipper will have a certain degree of wrinkles and bends, which will cause the zipper to slide smoothly, and even cause jamming or sticking, reducing the use experience of the zipper.

[0006] Finally, during the production and processing of zipper teeth, fine particles are generated due to surface friction, collision, and the operation of equipment, forming dust that adheres to the surface of the zipper teeth. This increases the frictional resistance, resulting in unsmooth zipper sliding, or even jamming or locking, reducing the user experience. Existing devices cannot clean them to a certain extent, affecting the overall processing efficiency. Summary of the Invention

[0007] In order to overcome the deficiencies of the prior art, the present invention provides a special-shaped tooth anti-loss zipper detection device. The present invention solves the problem that only tooth loss can be detected and the quality of zipper teeth cannot be comprehensively identified. On this basis, it solves the technical problems that the zipper tape will have a certain degree of wrinkles and bends, resulting in unsmooth zipper sliding and dust adhering to the surface of the zipper teeth, leading to unsmooth zipper sliding.

[0008] In order to achieve the above object, the present invention provides the following technical solution: A special-shaped tooth anti-loss zipper detection device, including a frame. A tensioning component is arranged at the bottom of the frame for tensioning two separated zipper tapes. A zipper head is fixedly installed on the front surface of the frame. A frequency detection sensor is fixedly installed on one side of the zipper head. A shrapnel is rotatably installed on the detection end of the frequency detection sensor for detecting whether the zipper teeth of the joined zipper are missing teeth. A detection roller is arranged below the frequency detection sensor for tensioning the zipper and opening the zipper teeth. Two detection plates are slidably installed in the middle of the detection roller for detecting the width of the lower part of the zipper teeth. Detection blocks are slidably installed on both sides of a storage box installed on one side wall of the two shrapnels for detecting the width of the upper part of the zipper teeth. A scraping plate and a first brush are fixedly installed on the lower surface of the storage box. A first dust suction hole located between the scraping plate and the first brush is also opened on the lower surface of the storage box. A punching component is arranged on one side of the detection roller for punching and marking the defects of the zipper teeth.

[0009] Through the settings of detectors, shrapnels, detection rollers, detection plates, detection blocks, scraping plates, and first brushes, etc., the joined teeth can be comprehensively detected, greatly improving the detection effect. At the same time of detection, the upper surface of the teeth can be cleaned of dust, preventing dust from adhering to the surface of the zipper teeth, improving the smoothness of zipper sliding, and enhancing the user experience of the zipper.

[0010] In the above special-shaped tooth anti-loss zipper detection device, the tensioning component includes a vertical plate fixedly installed at one end of the frame.

[0020] In the above-mentioned special-shaped chain tooth anti-loss zipper detection device, a fixing block is fixedly installed on the surface of the punching head. An air chamber is fixedly installed on the lower surface of the fixing block. A piston rod is slidably installed at the bottom of the air chamber. The bottom end of the piston rod is fixedly connected to the upper surface of the pigment box. A conduit communicating with the air chamber is fixedly installed inside the through hole.

[0021] Through the air chamber, the piston rod and the conduit, the waste can be blown out while punching, which is convenient for the discharge and collection of the waste, and greatly improves the punching effect.

[0022] In the above-mentioned special-shaped chain tooth anti-loss zipper detection device, a guide wheel is rotatably installed on the front surface of the frame. A tension wheel is arranged obliquely above the guide wheel. A second brush is slidably installed above the tension wheel.

[0023] Through the arrangement of the tension wheel and the second brush, the zipper teeth can be opened, and the residual dust in the separated zipper teeth can be swept away, further improving the dust removal effect.

[0024] In the above-mentioned special-shaped chain tooth anti-loss zipper detection device, a top plate is fixedly installed at the top of the tension wheel. A reciprocating lead screw is rotatably installed on the top of the top plate. A slider fixedly connected to the second brush is threadedly installed on the surface of the reciprocating lead screw.

[0025] Through the arrangement of the reciprocating lead screw and the slider, the second brush can be driven to slide reciprocally, further cleaning the zipper teeth, making the dust in the zipper teeth cleaned more thoroughly, and greatly improving the cleaning effect.

[0026] In the above-mentioned special-shaped chain tooth anti-loss zipper detection device, a fourth support plate is fixedly installed on one side of the top plate on the top of the frame. Two symmetrically arranged second vacuum cleaners are fixedly installed on the upper surface of the fourth support plate. The suction heads of the second vacuum cleaners are located on both sides of the bristles of the second brush.

[0027] Through the arrangement of the second vacuum cleaner, while sweeping the dust from the zipper teeth, the swept dust can be sucked out, greatly improving the dust removal effect.

[0028] In summary, compared with the prior art, a special-shaped chain tooth anti-loss zipper detection device provided by the present invention has the following beneficial effects:

[0029] In the present invention, through the settings of the roller, air holes, outer roller, grooves, brush plate, etc., the zipper cloth tape can be uniformly heated, which is convenient for flattening it, avoiding wrinkles and bending phenomena, greatly improving the quality of the zipper tape. While the zipper cloth tape is flattened, the dust can be controlled within a small range and then all the dust is sucked out, avoiding incomplete suction of the surrounding dust, and greatly improving the dust cleaning effect;

[0030] In the present invention, through the settings of a detection roller, a shrapnel, a detection plate, a detection block, a storage box, a scraper, a first brush, etc., the zipper teeth can be opened, which is convenient for improving the detection effect.

Detailed implementation manners

[0050] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0051] Embodiment 1:

[0052] A detection device for special-shaped chain teeth anti-loss zippers, referring to Figure 1 、 Figure 2 and Figure 3 , includes a frame 10. One end of the frame 10 is fixedly installed with a vertical plate 11. On the front surface of the other end of the frame 10, two discharging wheels 72 are rotatably installed. On the front surface of the bottom of the vertical plate 11, a first conveying wheel 12 is rotatably installed. On the front surface of the top of the vertical plate 11, a second conveying wheel 13 is fixedly installed. On the lower surface of the frame 10, a slide plate 14 is fixedly installed. On the front surface of the slide plate 14, a slide rod 15 is fixedly installed. On the surface of the slide rod 15, a third conveying wheel 16 is slidably installed. On the front surface of the frame 10, a fourth conveying wheel 17 is fixedly installed. During use, two zipper tapes pass through from the lower surface of the first conveying wheel 12, then pass through from the left side of the second conveying wheel 13, then pass through from the lower surface of the third conveying wheel 16, and finally are clamped by the two discharging wheels 72. On one side of one of the discharging wheels 72 and on one side of the frame 10, there is a motor. The output end of the motor drives the discharging wheel 72 to rotate, providing power for it. During conveying, the two discharging wheels 72 rotate and clamp the whole zipper to move forward, providing power for it. The rotation of the first conveying wheel 12 and the second conveying wheel 13 facilitates the conveying of the two zipper tapes. After conveying a certain distance, the discharging wheels 72 and the fourth conveying wheel 17 stop rotating, and the third conveying wheel 16 slides downward by its own weight to automatically tension the zipper tape, ensuring the stability and reliability of the conveyor belt. After the zipper tape is tensioned by gravity, the first conveying wheel 12 and the second conveying wheel 13 stop rotating, and the discharging wheel 72 pulls the zipper tape to move to one side. At this time, the zipper tape pulls the third conveying wheel 16 upward, facilitating the next tensioning operation, making the zipper tape always in a tensioned state and improving the conveying effect of the zipper tape. Therefore, in this solution, the movement and stop of the whole zipper are controlled by the rotation and stop of the discharging wheel 72. The motor is a prior art and has a certain reaction delay, which will not be elaborated too much in this solution.

[0053] Furthermore, referring to Figure 1A zipper head 18 is fixedly installed on the front surface of the frame 10 and on one side of the fourth conveying wheel 17. A mounting plate 19 is fixedly installed on the upper surface of the frame 10. A first support plate 20 is fixedly installed on the front surface of the mounting plate 19. A first elastic component 21 is fixedly installed on the lower surface of the first support plate 20. The first elastic component 21 includes a telescopic rod fixedly installed on the lower surface of the first support plate 20. A pressing plate 22 is fixedly installed on the bottom end of the telescopic rod. A spring penetrated by the telescopic rod is fixedly installed between the upper surface of the pressing plate 22 and the lower surface of the first support plate 20. When no zipper passes through, the pressing plate 22 The lower end surface of the zipper is basically flush with the bottom end surface of the zipper head 18 under the elastic support of the first elastic component 21. When in use, the two zipper tapes are closed and then transported when passing through the zipper head 18, which is convenient for subsequent chain tooth detection. When the zipper is closing and moving to one side, the thickness of the zipper itself will push the pressure plate 22 upward. At this time, the first elastic component on the pressure plate 22 will apply elastic pressure, so that the zipper can have a downward pressure when it moves to one side after closing, so that the zipper that has just been closed can be pressed relatively flat as a whole, ensuring the quality of the closing and improving the detection accuracy.

[0054] Example 2:

[0055] A special-shaped chain tooth missing zipper detection device, based on the embodiment 1, is further implemented, referring to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 14 An L-shaped plate 25 is fixedly mounted on the front surface of the frame 10, and a plurality of push cylinders 26 are fixedly mounted on the upper surface of the L-shaped plate 25. A support frame 27 is fixedly mounted on the output end of the push cylinder 26. A detection roller 28 is rotatably mounted inside the support frame 27, and a detection slot is provided inside the detection roller 28. A frequency detection sensor 23 used in conjunction with the detection roller 28 is fixedly mounted on the front surface of the frame 10. Two springs 24 are rotatably mounted on the detection end of the frequency detection sensor 23. The two springs 24 naturally droop as a whole. When the springs 24 are pushed upward, the frequency detection sensor 23 will perform detection and counting. At the same time, the frequency detection sensor 23 can also detect the amplitude of a single lifting of the spring 24. Among them, the frequency detection sensor 23 is a prior art and will not be elaborated in detail in this scheme.

[0056] From the attached Figure 1It can be seen that the entire detection roller 28 is basically higher than the pressing plate 22 on one side. When the device is started, the output end of the pushing cylinder 26 will push the support frame 27 upward, thereby pushing the detection roller 28 upward. At this time, the detection groove in the middle of the detection roller 28 will push the zipper upward, so that the zipper can be tightened upward by the detection roller 28. At this time, since the zipper is pushed upward, each tooth of the zipper will also expand outward, which is convenient for the detection work. When detecting, the frequency detection sensor 23 and the elastic piece 24 are located above the teeth of the zipper, and when the bottom end of the elastic piece 24 hangs naturally, it will abut against the upper surface of the tooth of the zipper. When the zipper is continuously dragged in the direction of the discharge wheel 72 during detection, since the elastic piece 24 can move up and down, the tooth of the zipper will push the elastic piece 24 upward when there is a tooth of the zipper. If there is no tooth of the zipper, one end of the elastic piece 24 will droop downward. Thus, the frequency detection sensor 23 detects whether there is a missing tooth of the zipper according to the number of times the elastic piece 24 swings up and down, and the height of each time the elastic piece 24 is lifted can be used to judge whether the upper end surface of the tooth is flat. If the heights of multiple teeth are the same, the height of the elastic piece 24 lifted will be the same. If there is an abnormal protrusion, the elastic piece 24 will be abnormally lifted, indicating that this tooth is deformed abnormally.

[0057] Further, referring to Figure 8 , an installation block 281 is fixedly installed inside the detection roller 28, and two detection plates 30 are slidably installed in the detection groove of the detection roller 28. On both side end faces of the installation block 281 between the two detection plates 30, first displacement sensors 29 are fixedly installed. The first displacement sensors 29 are prior art and will not be elaborated in detail in this solution. The detection ends of the first displacement sensors 29 face the detection plates 30. A return spring 31 is fixedly installed between one side of the detection plate 30 and the first displacement sensor 29. When the device is started, the zipper after closing the chain is pushed upward by the detection groove of the detection roller 28. Therefore, the two side walls of the teeth of the zipper abut against the opposite surfaces of the two detection plates 30. The return spring 31 will pull the detection plate 30 to always abut against the two side walls of the teeth of the zipper. At this time, if there are abnormal protrusions or abnormal depressions on both sides of the tooth, the detection plate 30 will slide. At this time, the first displacement sensor 29 can detect the sliding distance or stroke of the detection plate 30, so as to judge the abnormal deformation of the tooth here, and thus can detect whether the width of the tooth of the zipper is qualified.

[0058] It should be noted here that under the blockage of the chain cloth, the teeth of the zipper form upper teeth and lower teeth. The lower teeth clamped by the detection plate 30 mentioned above are the lower teeth under the chain cloth, and the detection is the width of the lower teeth.

[0059] Further, referring to Figure 8 、 Figure 14 and Figure 15, on one side wall of two elastic pieces 24, a storage box 35 is fixedly installed. Two side plates 39 are slidably arranged on both sides of the storage box 35. A detection block 40 is fixedly installed at the bottom of the side plate 39. The detection block 40 will abut against both side walls of the upper chain teeth of the zipper. And a spring is arranged between the side plate 39 and the storage box 35. A sliding rod is connected to the end face of the side plate 39 at the middle part of the spring. One end of the sliding rod is slidably arranged inside the storage box 35. On one side of the side plate 39 and on the end face of the storage box 35, a second displacement sensor 41 is arranged. The detection end of the second displacement sensor 41 faces the side plate 39.

[0060] During operation, since one end of the elastic piece 24 always abuts against the upper part of the zipper, the storage box 35 can also always move up and down synchronously according to the elastic piece 24. And the detection block 40 will also abut against both sides of the upper chain teeth under the action of the spring and the like. Similar to the above for detecting the lower chain teeth from above, if there are abnormal protrusions or depressions on the upper chain teeth, relative sliding will occur between the detection block 40 and the side plate 39. At this time, the second displacement sensor 41 can detect this stroke or distance, so as to judge the width dimension of the upper end chain teeth.

[0061] Furthermore, referring to Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 10 , Figure 11 and Figure 12 , since the zipper is tensioned upward by the detection roller 28, the chain teeth on the surface are all opened outward. Therefore, a first vacuum cleaner 42 is fixedly installed on the upper surface of the frequency detection sensor 23. A scraping plate 36 and a first brush 38 are fixedly installed on the lower surface of the storage box 35. A first suction hole 37 communicating with the first vacuum cleaner 42 is also opened on the lower surface of the storage box 35 and between the scraping plate 36 and the first brush 38. During the detection of the zipper, one end of the bottom of the scraping plate 36 will also abut against the upper surface of the zipper to scrape off burrs, dirt, etc. on the upper surface of the zipper. And the first brush 38 will further sweep it to scrape the dust out of the gaps between each zipper tooth. Then, the dust is sucked out through the first suction hole 37, avoiding the dust sticking to the surface of the zipper teeth, improving the smoothness of the zipper sliding, and improving the use experience of the zipper.

[0062] Furthermore, referring to Figure 7 and Figure 10At both ends of the detection roller 28 are belt rollers 32, and a plurality of air holes 33 are opened on the surface of the belt roller 32. Hot air blowers 34 are fixedly installed on the upper surface of the support frame 27 on both sides of the belt roller 32. The hot air blowers 34 are connected to the belt rollers 32. During testing, when the zipper tape of the detection roller 28 is tensioned, the zipper tape will be located on the outer surface of the belt roller 32. At this time, the hot air blower 34 blows hot air to the zipper tape through the air holes 33, so that the zipper tape is evenly heated, so that the relatively curved and wrinkled zipper tape just produced is softened, so that it can be flattened and shaped in the subsequent steps.

[0063] For further reference, Figure 1 and Figure 4 The front surface of the mounting plate 19 is fixedly mounted with a second support plate 43, the lower surface of the second support plate 43 is fixedly mounted with a second elastic component 44, the bottom of the second elastic component 44 is fixedly mounted with a U-shaped U-shaped plate 45, the second elastic component 44 includes a telescopic rod fixedly mounted on the lower surface of the second support plate 43, the outer side of the telescopic rod is fixedly mounted with a spring, the inner side of the U-shaped plate 45 is rotatably mounted with two pressure rollers 46 used in conjunction with the belt roller 32, the outer surface of the pressure roller 46 is fixedly mounted with an outer roller 47, the outer roller 47 is made of flexible material, and when in use, the pressure roller 46 drives the outer roller 4 7 abuts against the upper surface of the zipper tape. When the second elastic component 44 is used, the pressure roller 46 can be pressed downward. When the zipper tape is not placed, the outer roller 47 abuts against the surface of the belt roller 32. When the zipper tape passes, the pressure roller 46 drives the outer roller 47 to rotate and clamp the zipper tape between the outer roller 47 and the belt roller 32. At this time, since the belt roller continues to rotate and heats the zipper tape, the outer roller 47 can cooperate with the belt roller to flatten the zipper tape, eliminating wrinkles and deformation on its surface, greatly improving the quality of the zipper tape and enhancing the smoothness of the zipper sliding.

[0064] For further reference, Figure 11 and Figure 13 The surface of the outer roller 47 is provided with a plurality of grooves 48, and a brush plate 49 is fixedly installed inside the groove 48. The inner surface of the groove 48 is also provided with a second dust suction hole 50 corresponding to the bottom of the brush plate 49. The second dust suction hole 50 is connected to the inside of the outer roller 47, and the outer roller 47 is connected to the dust suction end of the first vacuum cleaner 42. When the zipper tape is flattened, the outer roller 47 will undergo elastic deformation, so that the groove 48 is squeezed and deformed and flattened, so that the brush plate 49 contacts the surface of the zipper tape, thereby scraping the dust on the surface of the zipper tape through the brush plate 49. During the scraping process, the second dust suction hole 50 sucks away the dust, thereby sucking away the dust, so that the surface dirt of the zipper tape can be cleaned, and the design of the second dust suction hole 50 being arranged inside the groove 48 can prevent too much dust from being blown outward, thereby improving the dust cleaning effect.

[0065] Example 3:

[0066] A special-shaped chain tooth anti-loss zipper detection device, on the basis of Embodiment 2, is further implemented. Refer to Figure 1 , Figure 6 and Figure 9 , a punching table 51 is fixedly installed on the front surface of the frame 10, a third support plate 52 is fixedly installed on the top of the mounting plate 19, a second cylinder 53 is fixedly installed on the top of the third support plate 52, the output end of the second cylinder 53 penetrates through the third support plate 52 and is in rotational fit, the output end of the second cylinder 53 is fixedly installed with a punching head 54, a through hole 55 is opened inside the punching head 54. When in use, if unqualified chain teeth are detected, the second cylinder 53 can be controlled to drive the punching head 54 to move downward for punching and marking, which is convenient for the staff to find and timely process the unqualified chain teeth. The middle part of the hollow punching head 54 is in a middle hole shape, which can improve the uniformity of pressure distribution during punching and reduce the risk of deformation or fracture of the rest of the fabric.

[0067] Furthermore, refer to Figure 9 , a fixing block 57 is fixedly installed in the middle of the punching head 54, an air chamber 58 is fixedly installed on the lower surface of the fixing block 57, a piston rod 59 is slidably installed inside the air chamber 58, a paint box 56 is fixedly installed at the bottom end of the piston rod 59, the punching head 54 slidably penetrates through the paint box 56 and is hermetically arranged with the paint box 56. A spring penetrated by 54 is fixedly installed between the upper surface of 56 and the lower surface of 57. An arc-shaped groove 61 is opened in the middle of the punching head 54, and a conduit 60 is fixedly installed inside the through hole 55, and this conduit 60 is communicated with the air chamber 58. When punching, the paint box 56 will first come into contact with the end face of the fabric, so as to be able to flatten the cloth tape around the punching, ensuring the punching effect. When the punching head 54 penetrates through the paint box 56, the arc-shaped groove 61 contacts the paint box 56, and then the paint in the paint box 56 enters the arc-shaped groove 61 and remains around the punching after punching, which is convenient for the staff to find and improves the work efficiency. At the same time, the paint box 56 drives the piston rod 59 to squeeze the air in the air chamber 58, so as to blow out the waste material left in the through hole 55 through the conduit 60 and fall into the collection box in the punching table 51, which is convenient for the discharge and collection of waste materials and greatly improves the punching effect.

[0068] It should be noted here that there is a certain distance between the detection position and the marking position, and the reason for not being in the same working station is that the zipper moves continuously at a constant speed during the detection process. Therefore, there is a certain delay time for the detection device to detect the abnormal chain teeth and react to control the motor to stop rotating the discharge wheel 72. During this time, the abnormal chain teeth have already moved forward a certain distance. If the two are in the same working station, it will instead affect the punching accuracy.

[0069] However, considering that the moving distance per second of the zipper and the delay time are basically determined, it can be judged that the distance that the abnormal zipper is dragged during each delay reaction process is basically determined. Therefore, the distance between the identification position and the detection position in this solution is determined according to the distance dragged by this delay. This is a conventional technology and will not be elaborated in this solution.

[0070] Embodiment 4:

[0071] A detection device for preventing missing teeth of special-shaped chain teeth zippers. On the basis of Embodiment 1, Embodiment 2 and Embodiment 3, a further embodiment is made. Refer to Figure 1 and Figure 16 , a guide wheel 62 is rotatably installed on the front surface of the frame 10, and a tension wheel 63 is arranged on the upper surface of the frame 10. During use, the zipper tape after chain closing detection passes through the lower surface of the guide wheel 62, then passes over the upper surface of the roller of the tension wheel 63, and finally passes through the middle of the discharge wheel 72 for transmission. The roller tensions the zipper tape and separates the chain teeth, facilitating the subsequent dust removal work.

[0072] Further, refer to Figure 16 , a top plate 64 is fixedly installed at the top of the tension wheel 63. A motor 65 and a mounting bracket 66 are fixedly installed on the upper surface of the top plate 64. The output end of the motor 65 is fixedly installed with a reciprocating lead screw 67. The surface of the reciprocating lead screw 67 has two mutually staggered thread lines, which can achieve the purpose of the driving block on the surface reciprocatingly moving with a single output end. This is a prior art and will not be elaborated in this solution. The reciprocating lead screw 67 is rotatably installed on one side of the mounting bracket 66. A chute is opened in the middle of the top plate 64. A slider 68 that slides inside the chute is threadedly driven on the outer surface of the reciprocating lead screw 67. A second brush 69 is fixedly installed at the bottom end of the slider 68. During use, the output end of the motor 65 drives the connected reciprocating lead screw 67 to rotate, thereby driving the slider 68 to reciprocatingly slide inside the chute, and further driving the second brush 69 to reciprocatingly slide to sweep the dust in the separated chain teeth, further improving the dust removal effect.

[0073] Further, refer to Figure 16 , two symmetrically arranged second vacuum cleaners 71 are fixedly installed on the upper surface of the fourth support plate 70 at the top of the frame 10. The second vacuum cleaners 71 are prior art and will not be elaborated in detail in this solution. The suction heads of the second vacuum cleaners 71 are located on both sides of the bristles of the second brush 69. When the second brush 69 reciprocatingly slides to sweep the dust in the chain teeth, the second vacuum cleaners 71 suck the swept dust, improving the dust removal effect.
