Description

Technical Field

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

[0002] In order to facilitate the identification of the gas filled in the gas cylinder, labels indicating gas information and safety warning information are generally attached to the surface of the gas cylinder. Before the gas cylinder is refilled with gas, not only the inside and outside of the gas cylinder need to be cleaned, but also the old labels need to be removed to facilitate the attachment of new labels.

[0003] Currently, the physical peeling method is mainly adopted, that is, tools such as a scraper or a squeegee are used to scrape the label off the surface of the gas cylinder (during which a hair dryer is used to preheat the glue inside the label first). After the paper label is removed, media such as alcohol and glue remover are applied to the remaining glue, and scraping is continued with a squeegee until the remaining glue is completely removed.

[0004] However, the existing label removal method is mainly manual throughout the whole process, and the whole process is long and time-consuming. Therefore, there is an urgent need to propose a cleaning device for residual labels on gas cylinders dedicated to removing gas cylinder labels to solve the above problems. Summary of the Invention

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

[0006] The present invention is implemented by the following technical solutions: a placement rack for placing a gas cylinder, a rotating pressing plate and a movable support frame are arranged on the placement rack, a pressing shaft is rotatably installed on the support frame, and the two cooperate to limit the gas cylinder on the placement rack and drive the gas cylinder to rotate circumferentially; An electromagnetic heating roller and a wiping roller are rotatably arranged on the placement rack, a cover shell fixedly connected to the support frame is slidably installed on the placement rack, a scraper and a hopper are arranged in the cover shell, and powder for smearing the residual glue of the label is arranged in the hopper, so that when the gas cylinder rotates, the label on its surface is heated by the electromagnetic heating roller, then the label is scraped off by the scraper, then powder is smeared on the residual glue of the label to remove the stickiness, and finally the residual glue after removing the stickiness is removed by the wiping roller.

[0007] As a further improvement of the above solution, the surface of the wiping roller is made of rubber material and is provided with thread grooves, so that it has a better cleaning effect on the residual glue on the surface of the gas cylinder when rotating.

[0008] As a further improvement of the above scheme, a base frame is elastically installed on the placement frame, and the electromagnetic heating roller and the wiping roller are rotatably installed on the base frame. A telescopic lever for pressing down the base frame is rotatably installed 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 be transferred to the position of the electromagnetic heating roller and the wiping roller, and the two will contact the gas cylinder.

[0009] 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.

[0010] As a further improvement of the above scheme, the telescopic lever consists of two sleeve frames, a forked frame slidably mounted on the two sleeve frames, a roller arranged on the forked frame for contacting the cam, and a pressing block arranged under the two sleeve frames for pressing the base frame.

[0011] As a further improvement of the above scheme, a connecting plate is fixedly installed on the support frame, an arc-shaped sliding opening is arranged on the connecting plate, and a protrusion is arranged on the fork frame, which passes through the arc-shaped sliding opening and is slidably connected thereto, so that the fork frame moves synchronously with the support frame and always keeps in contact with the cam.

[0012] 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 by rotating.

[0013] 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.

[0014] Compared with the prior art, the present invention has the following beneficial effects: A label cleaning device that can automatically clean gas cylinder labels is formed by combining a placement rack, a plate, an axle, an electromagnetic heating roller, a wiping roller, a scraper, and a hopper provided with powder. 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 because of its stickiness. After the gas cylinder is cleaned of the label, it does not need to be dried or air-dried, eliminating the subsequent waiting time for drying and improving the overall processing efficiency. The electromagnetic heating roller and the wiping roller are arranged on a base frame with an elastic structure, and a cam and a telescopic lever are arranged to control the lifting and lowering of the base frame, so that the electromagnetic heating roller and the wiping roller will come into contact with the cylinder body only when the label on the gas cylinder is transferred to the electromagnetic heating roller and the wiping roller, so that 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; By arranging an arc-shaped rack on the cam and arranging a circular gear that can transmit 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, so as to accurately sprinkle the powder and avoid waste caused by excessive discharge of powder.

[0020] Please refer to Figure 5 to Figure 8 , a base frame 7 is elastically installed on the second platform 104 of the placement rack 1. Four screw columns 701 distributed in a rectangle are threadedly installed on the second platform 104. All four screw columns 701 penetrate through the base frame 7 and are slidably connected thereto, and springs 702 are sleeved on all four screw columns 701. The two ends of the springs 702 abut against the base frame 7 and the second platform 104 respectively. The electromagnetic heating roller 8 and the wiping roller 10 are rotatably installed on the base frame 7. A second motor 9 is fixedly installed on the base frame 7. Gears are provided on the output shaft of the second motor 9 and the shaft rod of the wiping roller 10, and the two gears are meshed with each other. A telescopic lever 15 for pressing down the base frame 7 is rotatably installed on the placement rack 1. A cam 16 for controlling the pressing down of the telescopic lever 15 is fixedly sleeved on the abutting 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 two will only contact the gas cylinder when the label on the gas cylinder is transferred to the positions of the electromagnetic heating roller 8 and the wiping roller 10.

[0021] Through the above technical solution, when the label on the gas cylinder is only transferred to the positions of the electromagnetic heating roller 8 and the wiping roller 10, the electromagnetic heating roller 8 and the wiping roller 10 will contact the gas cylinder body, so that the electromagnetic heating roller 8 can focus on heating the label area of the gas cylinder, avoiding overheating the gas cylinder, and the wiping roller 10 can focus on wiping and cleaning the label area of the gas cylinder, avoiding excessive wear of the wiping roller 10.

[0022] Please refer to Figures 6 to 8 , the cam 16 is composed of a small-diameter semi-circular ring in the upper half and a large-diameter semi-circular ring in the lower half. The small-diameter semi-circular ring occupies a 100-degree angular range of the entire cam 16, which is used for aligning with the label on the gas cylinder. When the label on the gas cylinder is facing down, it is also in the downward position, so that the telescopic lever 15 and the base frame 7 rebound and rise.

[0023] Please refer to Figure 8 , the telescopic lever 15 is composed of two sleeve frames 151, a bifurcated frame 152 slidably installed on the two sleeve frames 151, a roller 153 provided on the bifurcated frame 152 for contacting the cam 16, and a pressing block 154 provided below the two sleeve frames 151 for pressing the base frame 7. The two sleeve frames 151 are rotatably installed on the second platform 104; Please refer to Figure 8A 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 keeps in contact with the cam 16.

[0024] Please combine Figure 9 A sponge roller 14 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 meshing 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 when the label on the gas cylinder is transferred to the hopper 13, the sponge roller 14 will rotate and discharge the powder.

[0025] 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, so as to accurately sprinkle the powder and avoid waste caused by excessive discharge of powder.

[0026] The implementation principle of the gas cylinder residual label cleaning device in this application is: 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), then drive the support rack 5 to move through the electric push rod 4, 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 against the abutment plate 3; Start the first motor 2, the first motor 2 drives the gas cylinder and the shaft 6 to rotate through the plate 3 (refer to Figure 9 Clockwise rotation), when the small diameter semicircular ring on the cam 16 moves downward, the telescopic lever 15 without the restriction of the large diameter semicircular ring will release 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; 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 the powder on the residual glue by rotating. When the residual glue attached with the powder is transferred to the wiping roller 10, during this process, the second motor 9 drives the wiping roller 10 to rotate, and the rotating wiping roller 10 can remove the residual glue.
