Description

Technical Field

[0001] This utility model relates to the field of bag making machine traction cleaning technology, and in particular to a dual-channel traction cleaning device for a bag making machine. Background Technology

[0002] A bag-making machine is a machine that produces various plastic or other material packaging bags. Its processing range includes packaging bags of various sizes, thicknesses, and specifications made of plastic or other materials. Generally, plastic packaging bags are the main product. During the traction process, the outside of the existing packaging bags is prone to attracting dust due to static electricity. If this is not dealt with, it will lead to poor quality of the packaging bags after subsequent winding, and in severe cases, it may damage the packaging bags. In addition, traditional dust collection devices require stopping the machine to clean the filter screen, which affects production efficiency. Utility Model Content

[0003] In response to existing patents, this invention addresses the technical problem that existing packaging bags easily attract dust due to static electricity during the traction and winding process. If not addressed, this can lead to poor quality of the finished packaging bags and, in severe cases, damage to the bags. Furthermore, traditional dust collection devices require stopping the machine to clean the filter, which affects production efficiency. This invention provides a dual-channel traction cleaning device for bag making machines.

[0004] The technical solution adopted by this utility model is: a dual-channel traction cleaning device for a bag making machine, comprising: a cleaning mechanism, a traction mechanism, two U-shaped channels, and a connecting plate disposed between the two U-shaped channels. The cleaning mechanism includes two cleaning components respectively disposed in the two U-shaped channels, a dust suction mechanism disposed on the upper side of the connecting plate, and a dust removal mechanism disposed on the dust suction mechanism. The cleaning component includes an adjusting plate fixed in the U-shaped channel, a scraper elastically slidingly engaged with one side of the adjusting plate, and a dust suction head disposed on one side of the scraper.

[0005] Furthermore, the traction mechanism includes an active traction roller rotatably coupled to the entrance end of the U-shaped channel, a driven traction roller rotatably coupled to the U-shaped channel, a transmission shaft disposed between the two active traction rollers, and a first servo motor disposed on one side of one of the U-shaped channels. The output shaft of the first servo motor extends into and is fixedly connected to one of the active traction rollers. The two scrapers in the cleaning assembly correspond to the active traction roller and the driven traction roller in the U-shaped channel, respectively.

[0006] Furthermore, the vacuuming mechanism includes a vacuum box fixed to the connecting plate and connected to a plurality of vacuum heads, a filter screen located in the upper part of the vacuum box, a suction fan connected to the vacuum box, a Y-shaped main pipe connected to the lower part of the vacuum box, and a branch pipe connected between the side of the Y-shaped main pipe and the vacuum heads.

[0007] Furthermore, the dust collection box has a notch on its side, and the dust removal mechanism includes a collection box fixed in the notch, a scraper on the upper side of the collection box, and a second servo motor on the upper side of the dust collection box for driving the filter screen to rotate.

[0008] Furthermore, the collection box has a notch on its upper side, and the scraper is located at one end of the notch.

[0009] Furthermore, the dust removal mechanism also includes a guide strip that slides vertically within the dust collection box, a fan-shaped cleaning plate that rotates elastically on the upper side of the guide strip, and multiple cleaning needles located at the bottom end of the fan-shaped cleaning plate. The upper side of the fan-shaped cleaning plate is provided with an arc-shaped groove, and a curved spring return slide rod is provided between the inner wall of the arc-shaped groove and the guide strip. An electric push rod for driving the guide strip to slide is provided on the upper side of the dust collection box. The vertical cross-section of the guide strip and the arc-shaped groove is a T-shaped structure, and the fan-shaped cleaning plate rotates on the guide strip through the arc-shaped groove.

[0010] The beneficial effects of this utility model are:

[0011] By installing elastic scrapers at the entrance ends of both U-shaped channels, the friction between the active and driven traction rollers and the scrapers generates stronger electrostatic attraction to remove dust from the film. This makes it easier for the scrapers to remove dust from the active and driven traction rollers during traction, while the dust suction head simultaneously removes the dust, achieving simultaneous traction and real-time cleaning in both channels, thus improving the cleanliness of the film and the stability of traction.

[0012] By setting up a filter screen for filtration while another part of the filter screen is cleaned, and then rotating the filter screen alternates between the working and cleaning parts, the filter screen can work continuously, avoiding downtime for cleaning the filter screen and affecting production efficiency.

[0013] By using cleaning needles to push out dust from the filter holes on the filter screen, and then scraping it off with scrapers, the cleaning effect of the filter screen can be improved, maintaining the filter screen in good filtration condition, reducing the probability of the filter screen becoming clogged and affecting filtration and dust collection, and avoiding downtime for cleaning the filter screen, which would affect production efficiency.

[0023] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0024] To address the problems existing in the background art, this application proposes the following technical solution:

[0025] A dual-channel traction cleaning device for a bag making machine includes: a cleaning mechanism 1, a traction mechanism 2, two U-shaped channels 3, and a connecting plate 4 disposed between the two U-shaped channels 3. The cleaning mechanism 1 includes two cleaning components 101 respectively disposed in the two U-shaped channels 3, a dust suction mechanism 102 disposed on the upper side of the connecting plate 4, and a dust removal mechanism 103 disposed on the dust suction mechanism 102. The cleaning component 101 includes an adjusting plate 1011 fixed in the U-shaped channel 3, a scraper 1012 elastically slidably fitted on one side of the adjusting plate 1011, and a dust suction head 1013 disposed on one side of the scraper 1012. An elastic damper is provided between the adjusting plate 1011 and the scraper 1012.

[0026] Furthermore, the traction mechanism 2 includes an active traction roller 201 rotatably engaged with the entrance end of the U-shaped channel 3, a driven traction roller 202 rotatably engaged with the U-shaped channel 3, a transmission shaft 203 disposed between the two active traction rollers 201, and a first servo motor 204 disposed on one side of one of the U-shaped channels 3. The output shaft of the first servo motor 204 extends into and is fixedly connected to one of the active traction rollers 201. The two scrapers 1012 in the cleaning assembly 101 correspond to the active traction roller 201 and the driven traction roller 202 in the U-shaped channel 3, respectively.

[0027] Furthermore, the vacuuming mechanism 102 includes a vacuum box 1021 fixed on the connecting plate 4 and connected to a plurality of vacuum heads 1013, a filter screen 1022 located in the upper part of the vacuum box 1021, a suction fan 1023 connected to the vacuum box 1021, a Y-shaped main pipe 1024 connected to the lower part of the vacuum box 1021, and branch pipes 1025 connected between the side of the Y-shaped main pipe 1024 and the vacuum heads 1013.

[0028] Furthermore, the dust collection box 1021 has a notch 1026 on its side, and the dust removal mechanism 103 includes a collection box 1031 fixed in the notch 1026, a scraper 1032 on the upper side of the collection box 1031, and a second servo motor 1033 on the upper side of the dust collection box 1021 for driving the filter screen 1022 to rotate.

[0029] Furthermore, the upper side of the collection box 1031 is provided with a notch 1034, and the scraper 1032 is located at one end of the notch 1034.

[0030] Furthermore, the dust removal mechanism 103 also includes a guide strip 1035 that slides vertically within the dust collection box 1021, a fan-shaped cleaning plate 1036 that rotates elastically on the upper side of the guide strip 1035 and corresponds to the collection box 1031, and a plurality of cleaning needles 1037 located at the bottom of the fan-shaped cleaning plate 1036. The upper side of the fan-shaped cleaning plate 1036 is provided with an arc groove 1038, and a curved spring return slide rod 1039 is provided between the inner wall of the arc groove 1038 and the guide strip 1035. The upper side of the dust collection box 1021 is provided with an electric push rod 1030 for driving the guide strip 1035 to slide. The curved spring return slide rod 1039 includes a curved barrel and a curved rod that slides at one end within the curved barrel, and a spring fixed between the inner wall of the curved barrel and the curved rod. The vertical cross-section of the guide strip 1035 and the arc groove 1038 is a T-shaped structure, and the fan-shaped cleaning plate 1036 rotates on the guide strip 1035 through the arc groove 1038.

[0031] Working principle: The first servo motor 204 drives the active traction roller 201 to rotate, which works with the driven traction roller 202 to transport the film. The active traction roller 201 and the driven traction roller 202 rub against the scraper 1012 to generate stronger static electricity to attract dust off the film. The scraper 1012 scrapes the dust off the active traction roller 201 and the driven traction roller 202. The suction fan 1023 sucks the dust scraped by the scraper 1012 into the dust collection box 1021 through the dust collection head 1013 and filters it through the filter screen 1022.

[0032] The dust is filtered through the filter screen 1022 area outside the collection box 1031. The electric push rod 1030 drives the guide bar 1035 to slide the fan-shaped cleaning plate 1036 and cleaning needle 1037 vertically, causing the cleaning needle 1037 to insert into the filter holes of the filter screen 1022 located above the collection box 1031, pushing out the dust from the filter holes. The second servo motor 1033 drives the filter screen 1022 to rotate in a step-by-step manner. The filter screen 1022 drives the fan-shaped cleaning plate 1036 and cleaning needle 1037 to rotate on the guide bar 1035, protecting the cleaning needle 1037 from being inserted into the filter holes of the filter screen 1022. The scraper 1032 scrapes away the dust in the area of ​​the filter screen 1022 cleaned by the cleaning needle 1037. Then, the electric push rod 1030 drives the guide bar 1035 to move the fan-shaped cleaning plate 1036 and cleaning needle 1037 upwards, bending... The spring-reset slide bar 1039 drives the fan-shaped cleaning plate 1036 and cleaning needle 1037 to rotate and reset on the guide bar 1035. The cleaned part of the filter screen 1022 rotates to the outside of the collection box 1031, completing the switching between the cleaned area and the filtration working area on the filter screen 1022. While one part of the filter screen 1022 is performing filtration, the other part is being cleaned. This allows for alternating between the working and cleaning parts of the filter screen 1022 by rotating it, ensuring continuous operation of the filter screen 1022 and avoiding downtime for cleaning, which would affect production efficiency. The cleaning needle 1037 pushes out the dust from the filter holes on the filter screen 1022, which is then scraped off with the scraper 1032, improving the cleaning effect of the filter screen 1022, maintaining its good filtration condition, and reducing the probability of the filter screen 1022 becoming clogged and affecting filtration and dust collection.
