Description

Technical Field

[0001] The present invention relates to the technical field of gas cylinder processing, and in particular to a device for cleaning residual labels on gas cylinders. Background Art

[0002] In order to facilitate the identification of the gas filled in the gas cylinder, the surface of the gas cylinder is generally affixed with a label indicating the gas information and safety warning information. Before refilling the gas cylinder, not only the inside and outside of the gas cylinder need to be cleaned, but the old label also needs to be removed to facilitate the affixing of the new label.

[0003] At present, the main method used is the physical peeling method, which is to scrape the label from the surface of the gas cylinder with a tool such as a scraper or scraper (during the process, a hair dryer is used to preheat the glue in the label). After the paper label is removed, alcohol, glue remover and other media are applied on the remaining glue, and the scraper is used to continue scraping until the remaining glue is completely removed.

[0004] However, the entire process of the existing label removal method is mainly carried out manually, and the entire process is long and time-consuming. Therefore, it is urgent to propose a gas cylinder residual label cleaning device specifically for removing gas cylinder labels to solve the above problems. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a device for cleaning residual labels on gas cylinders.

[0006] The present invention is implemented by the following technical solution: a placement rack for placing gas cylinders, the placement rack is provided with a rotating plate and a movable support frame, the support frame is rotatably mounted with a shaft, the two cooperate to limit the gas cylinders on the placement rack and drive the gas cylinders to rotate circumferentially;

[0007] An electromagnetic heating roller and a wiping roller are rotatably installed on the placement rack, and a cover shell fixedly connected to the support frame is slidably installed on the placement rack. A scraper and a hopper are provided in the cover shell, and powder for smearing the residual glue on the label is provided in the hopper. In this way, when the gas cylinder rotates, the label on its surface is heated by the electromagnetic heating roller, and then the label is scraped off by the scraper, and then powder is applied to the residual glue on the label to remove it, and finally the residual glue that has been debonded is removed by the wiping roller.

[0008] As a further improvement of the above solution, the surface of the wiping roller is made of rubber and is provided with a threaded groove, so that it has a better cleaning effect on the residual glue on the surface of the gas cylinder when it rotates.

[0009] As a further improvement of the above scheme, a base frame is elastically mounted on the placement frame, and the electromagnetic heating roller and the wiping roller are rotatably mounted on the base frame. A telescopic lever for pressing down the base frame is rotatably mounted on the placement frame, and a fixed sleeve on the shaft is provided with a cam for controlling the downward pressure of the telescopic lever, so as to control the distance between the electromagnetic heating roller and the wiping roller and the gas cylinder, so that the label on the gas cylinder will only contact the gas cylinder when it is transferred to the position of the electromagnetic heating roller and the wiping roller.

[0010] As a further improvement of the above scheme, the cam consists of a small-diameter semicircular ring in the upper part and a large-diameter semicircular ring in the lower part. The small-diameter semicircular ring occupies an angle range of 100 degrees of the entire cam. It is used to align with the label on the gas cylinder. When the gas cylinder label is facing downward, it is also in a downward position, so that the telescopic lever and the base frame rebound and rise.

[0011] As a further improvement of the above solution, the telescopic lever consists of two sleeve frames, a fork frame slidably mounted on the two sleeve frames, a roller arranged on the fork frame for contacting the cam, and a pressure block arranged under the two sleeve frames for pressing the base frame.

[0012] As a further improvement of the above solution, a connecting plate is fixedly installed on the support frame, an arc-shaped sliding mouth is provided on the connecting plate, and a protrusion is provided on the fork frame. The protrusion passes through the arc-shaped sliding mouth and is slidably connected with it, so that the fork frame moves synchronously with the support frame and always maintains contact with the cam.

[0013] As a further improvement of the above solution, a sponge roller connected to a cam transmission is rotatably installed at the discharge port of the hopper, and the sponge roller can evenly discharge the powder in the hopper through rotation.

[0014] As a further improvement of the above solution, an arc-shaped rack is provided on one side of the cam, and a circular gear meshing with the arc-shaped rack is fixedly mounted on the shaft at one end of the sponge roller, so that the sponge roller will rotate and discharge the powder only when the label on the gas cylinder is transferred to the hopper.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By cooperating with a placement rack, a plate, a shaft, an electromagnetic heating roller, a wiping roller, a scraper, and a hopper provided with powder, a label cleaning device is formed that can automatically clean gas cylinder labels. Compared with the existing method of manually scraping labels, it is more convenient and efficient. Compared with the cleaning method of washing and scraping, it uses powder to remove the residual glue of the label, solving the problem that the residual glue is difficult to remove due to its stickiness. After the gas cylinder is cleaned, it does not need to be dried or air-dried, eliminating the subsequent waiting time for drying and improving the overall processing efficiency.

[0017] By arranging the electromagnetic heating roller and the wiping roller on a base frame with an elastic structure, and providing a cam and a telescopic lever that can control the lifting and lowering of the base frame, the electromagnetic heating roller and the wiping roller will only come into contact with the cylinder body when the label on the gas cylinder is transferred to the electromagnetic heating roller and the wiping roller. In this way, the electromagnetic heating roller can focus on heating the label area of ​​the gas cylinder to avoid excessive heating of the gas cylinder, and the wiping roller can focus on wiping and cleaning the label area of ​​the gas cylinder to avoid excessive wear of the wiping roller.

[0018] By setting an arc-shaped rack on the cam and a circular gear that can transmit power to the arc-shaped rack on the sponge roller on the hopper, the cam that rotates synchronously with the gas cylinder can automatically drive the sponge roller to rotate when the label on the gas cylinder is transferred to the hopper area, thereby accurately sprinkling the powder and avoiding waste caused by excessive discharge of powder.

[0033] An electromagnetic heating roller 8 and a wiping roller 10 are rotatably provided on the placement rack 1. The surface of the wiping roller 10 is made of rubber and is provided with a threaded groove, so that it can have a better cleaning effect on the residual glue on the surface of the gas cylinder when it rotates. A cover 11 fixedly connected to the support frame 5 is slidably installed on the placement rack 1. A curtain can also be provided on the cover 11 to block the interior of the cover 11 to prevent the powder in the hopper 13 from spreading when it is sprinkled. A scraper 12 and a hopper 13 are provided in the cover 11. The scraper 12 is composed of a blade holder, and the cover An internal threaded barrel is also rotatably mounted on the shell 11, and a screw is mounted on the internal thread of the internal threaded barrel. One end of the screw is fixedly connected to the tool holder. By rotating the internal threaded barrel, the distance between the scraper 12 and the gas cylinder can be adjusted. Powder for smearing the residual glue of the label is provided in the hopper 13. The powder can be a powdered material such as flour. In this way, when the gas cylinder rotates, the label on its surface is heated by the electromagnetic heating roller 8, and then the label is scraped off by the scraper 12, and then the powder is applied to the residual glue of the label to remove it, and finally the residual glue that has been debonded is removed by the wiping roller 10.

[0034] Through the above technical solution, a label cleaning device that can automatically clean gas cylinder labels is formed. Compared with the existing method of manually scraping off labels, it is more convenient and efficient. Compared with the cleaning method of washing and scraping, it uses powder to remove the residual glue on the label, solving the problem that the residual glue is difficult to remove cleanly due to its stickiness. After the gas cylinder is cleaned, it does not need to be dried or air-dried, eliminating the subsequent waiting time for drying and improving the overall processing efficiency.

[0035] Please refer to Figure 5 to Figure 8 , a base frame 7 is elastically mounted on the second platform 104 of the placement frame 1, and four rectangularly distributed screw columns 701 are threadedly mounted on the second platform 104. The four screw columns 701 all penetrate the base frame 7 and are slidably connected thereto, and the four screw columns 701 are all sleeved with springs 702, and the two ends of the spring 702 are respectively against the base frame 7 and the second platform 104. The electromagnetic heating roller 8 and the wiping roller 10 are rotatably mounted on the base frame 7, and a second motor 9 is fixedly mounted on the base frame 7. The output shaft of the second motor 9 and the shaft rod of the wiping roller 10 are both provided with gears, and the two gears are engaged with each other. A telescopic lever 15 for pressing down the base frame 7 is rotatably mounted on the placement frame 1, and a cam 16 for controlling the downward pressure of the telescopic lever 15 is fixedly sleeved on the abutment shaft 6, so as to control the distance between the electromagnetic heating roller 8 and the wiping roller 10 and the gas cylinder, so that the electromagnetic heating roller 8 and the wiping roller 10 will contact the gas cylinder only when the label on the gas cylinder is transferred to the position of the electromagnetic heating roller 8 and the wiping roller 10.

[0036] Through the above technical solution, the electromagnetic heating roller 8 and the wiping roller 10 will only come into contact with the gas cylinder body when the label on the gas cylinder is transferred to the electromagnetic heating roller 8 and the wiping roller 10, so that the electromagnetic heating roller 8 can focus on heating the label area of ​​the gas cylinder to avoid excessive heating of the gas cylinder, and the wiping roller 10 can focus on wiping and cleaning the label area of ​​the gas cylinder to avoid excessive wear of the wiping roller 10.

[0037] Please combine Figures 6 to 8 The cam 16 is composed of a small-diameter semicircular ring in the upper part and a large-diameter semicircular ring in the lower part. The small-diameter semicircular ring occupies an angle range of 100 degrees of the entire cam 16. It is used to align with the label on the gas cylinder. When the gas cylinder label is facing down, it is also in a downward position, so that the telescopic lever 15 and the base frame 7 rebound and rise.

[0038] Please combine Figure 8 The telescopic lever 15 is composed of two sleeves 151, a fork frame 152 slidably mounted on the two sleeves 151, a roller 153 provided on the fork frame 152 for contacting the cam 16, and a pressure block 154 provided under the two sleeves 151 for pressing the base frame 7. Both sleeves 151 are rotatably mounted on the second platform 104.

[0039] Please combine Figure 8 A connecting plate 156 is fixedly mounted on the support frame 5, and an arc-shaped sliding opening is provided on the connecting plate 156. A protrusion 155 is provided on the fork frame 152, and the protrusion 155 passes through the arc-shaped sliding opening and is slidably connected thereto, so that the fork frame 152 moves synchronously with the support frame 5 and always maintains contact with the cam 16.

[0040] Please combine Figure 9 A sponge roller 14 that is rotatably connected to a cam 16 is rotatably installed at the discharge port of the hopper 13. The sponge roller 14 can evenly discharge the powder in the hopper 13 by rotating. An arc-shaped rack 17 is provided on one side of the cam 16. A circular gear 18 that meshes with the arc-shaped rack 17 is fixedly installed on the shaft at one end of the sponge roller 14. The shaft at one end of the sponge roller 14 is rotatably connected to the support frame 5, so that the sponge roller 14 will rotate and discharge the powder only when the label on the gas cylinder is transferred to the hopper 13.

[0041] Through the above technical solution, the cam 16 that rotates synchronously with the gas cylinder can automatically drive the sponge roller 14 to rotate when the label on the gas cylinder is transferred to the hopper 13 area, thereby accurately sprinkling the powder and avoiding waste caused by excessive discharge of powder.

[0042] The implementation principle of the device for cleaning residual labels on gas cylinders in this application is as follows:

[0043] When cleaning the label on the gas cylinder, place the gas cylinder on the placement rack 1 (the gas cylinder label needs to face upwards and align with the small diameter semicircular ring of the cam 16), and then the electric push rod 4 drives the support rack 5 to move, and the support rack 5 drives the cover 11 to cover the upper body of the gas cylinder, and drives the abutment shaft 6 to press the gas cylinder tightly against the abutment plate 3;

[0044] Start the first motor 2, the first motor 2 drives the gas cylinder and the shaft 6 to rotate through the disc 3 (refer to Figure 9 (rotate clockwise) When the small-diameter semicircular ring on the cam 16 moves downward, the telescopic lever 15, which is no longer restricted by the large-diameter semicircular ring, releases the pressure on the base frame 7. At this time, the base frame 7, driven by the spring 702, drives the electromagnetic heating roller 8 and the wiping roller 10 to rise and stick to the surface of the gas cylinder to contact the label on the surface of the gas cylinder. The label on the gas cylinder will contact the electromagnetic heating roller 8 after passing through the wiping roller 10 and be heated in the process.

[0045] The label is then transferred to the scraper 12, which scrapes off the label. At this time, the residual glue on the label (heated and melted) is transferred to the bottom of the hopper 13, and the cam 16 drives the sponge roller 14 to rotate. The sponge roller 14 evenly sprinkles powder on the residual glue through rotation. When the residual glue with powder is transferred to the wiping roller 10, the second motor 9 drives the wiping roller 10 to rotate during this process, and the rotating wiping roller 10 can remove the residual glue.

[0046] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
