Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and particularly relates to a cleaning mechanism for a tipping paper sizing device. Background Art

[0002] On some packaging production lines, it is necessary to apply glue to the paper tape to facilitate subsequent processes such as pasting. For example: in the manufacturing process of filter cigarettes in the tobacco industry, it is necessary to use a sizing device to coat and apply glue to the tipping paper tape so that the tipping paper cut into pieces can wrap and bond the cigarette rod and the filter tip to form a filter cigarette. During the operation of the tipping paper sizing device, glue will remain in the parts performing sizing. If too much glue accumulates, it will affect the sizing quality of the tipping paper, thereby affecting the quality of the final cigarette product. Therefore, it is necessary to design a cleaning mechanism for the sizing device to achieve the function of automatic maintenance and cleaning, improve the production efficiency and automation level of the unit, and reduce the labor intensity.

[0003] The applicant's prior application patent CN112387677A discloses a device for cleaning the glue application parts of cigarette tipping paper. This device uses high-pressure water flushing to clean the glue nozzle. Since the outlet pipeline is fixed and in order to maintain the water pressure, the impact area of the outlet water flow is small. In actual use, it is found that this cleaning method has a small cleaning area for the sizing parts and is difficult to clean the thick and dried glue scale on the surface of the sizing parts, with a low cleaning rate, thus affecting the sizing quality. Therefore, it is necessary to manually disassemble the tipping paper sizing device regularly for in-depth cleaning, which increases the maintenance difficulty of the sizing equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cleaning mechanism for a tipping paper sizing device to solve the problems of difficult cleaning of thick and dried glue scale on the surface of the sizing parts and low cleaning rate existing in the prior art when using high-pressure water flushing to clean a rotary tipping paper sizing device.

[0005] To achieve the above purpose, the utility model provides a cleaning mechanism for a tipping paper sizing device. The cleaning mechanism includes a water tank for containing a cleaning liquid, and a scraping strip fixed at one end is arranged inside the water tank;

[0006] The scraping strip is used to contact and move relative to the surface of the sizing part when the sizing part of the tipping paper sizing device rotates around its axis, so as to scrape the residual glue and other foreign matters on the sizing part. Further, the scraping strip is used to be in close contact with the glue outlet of the plate-shaped slit nozzle rotated to the position of the scraping strip after the cleaning action is completed to achieve glue sealing during shutdown.

[0007] In some alternative embodiments, the scraping strip is arranged below the liquid level of the cleaning liquid.

[0008] In some alternative embodiments, the material of the squeegee is an elastic material.

[0009] In some alternative embodiments, the material of the squeegee is nylon or rubber.

[0023] Figure 3 FIG. 16 is a schematic structural diagram of Embodiment 2 of the cleaning mechanism of a tipping paper sizing device provided by the present invention. Detailed Embodiments

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0025] Figure 1 FIG. 25 is a schematic structural diagram of Embodiment 1 of the cleaning mechanism of a tipping paper sizing device provided by the present invention. As Figure 1 shown in FIG. 27, the cleaning mechanism includes a water tank 24 for containing a cleaning liquid 21 (such as water). A scraping strip 26 is arranged inside the water tank 24 and fixed at one end. The scraping strip 26 is used to contact and move relative to the surface of the sizing component 1 when the sizing component 1 of the tipping paper sizing device rotates around its axis, so as to scrape the residual glue and other foreign matters on the sizing component 1.

[0026] As Figure 1 shown in FIG. 32, the tipping paper sizing device to which the cleaning device in the embodiment of the present invention is applied includes a sizing component 1 that can rotate around its axis for sizing. Its outer surface is approximately cylindrical. The sizing component 1 includes a on-off valve 11 and a plate-shaped slit nozzle 12. The axis of the sizing component 1 is installed parallel to the cleaning liquid surface of the water tank 24. The upper part of the sizing component 1 is higher than the top of the water tank 24, and the lower part is lower than the above-mentioned cleaning liquid surface. As Figure 2A shown in FIG. 34, during the rotation of the sizing component 1 around its axis, when the on-off valve 11 and the plate-shaped slit nozzle 12 are rotated to the sizing position on the upper side of the sizing component 1, the tipping paper 6 between the first guide roller 4 and the second guide roller 5 can be sized; as Figure 2BAs shown, when the on-off valve 11 and the plate-shaped slit nozzle 12 are rotated to the cleaning position below the sizing member 1, the on-off valve 11 and the plate-shaped slit nozzle 12 can be cleaned by the cleaning liquid 21 in the water tank 24. At the same time, the scraping strip 26 contacts the sizing member 1 and moves relatively, scraping the residual glue and other foreign matters on the plate-shaped slit nozzle 12 and the on-off valve 11.

[0027] Further, the scraping strip 26 is used to closely contact the glue outlet of the plate-shaped slit nozzle 12 rotated to the position of the scraping strip 26 after the cleaning operation is completed, so as to achieve the glue sealing effect at the glue outlet during shutdown.

[0028] Preferably, as Figure 1 shown, the scraping strip 26 is arranged below the liquid level of the cleaning liquid. Before cleaning the nozzle, the cleaning liquid 21 is first pumped into the water tank 24 to make the water level higher than the position of the scraping strip 26, so that the scraping strip 26 can be wetted by water when scraping the sizing member 1, improving the scraping effect.

[0029] Preferably, the material of the scraping strip 26 is an elastic material, such as nylon or rubber, so that the cleaning device can be applicable to the sizing member 1 with a non-smooth cylindrical surface shape. For example: when there is a groove on one side of the plate-shaped slit nozzle 12 close to the on-off valve 11, on the premise of avoiding scratching the plate-shaped slit nozzle 12, when the groove on the plate-shaped slit nozzle 12 rotates to the position relative to the scraping strip 26, the elastic scraping strip 26 can extend into the groove to scrape off dirt, achieving a better cleaning effect. Specifically, when the tipping paper sizing device is not working, after the plate-shaped slit nozzle 12 is cleaned, keep its outlet below the liquid level of the cleaning liquid 21.

[0030] In some embodiments, as Figure 1 shown, the cleaning mechanism provided by the present invention further includes air nozzles 28, 29 arranged at the upper left and / or upper right of the water tank 24. The air nozzles 28, 29 form an angle with the vertical direction and the bottom ends are inclined towards the sizing member 1. When starting up, the plate-shaped slit nozzle 12 and the on-off valve 11 are rotated to the sizing position by clockwise or counterclockwise rotation. If the sizing member 1 is rotated to the sizing position by clockwise rotation, the left air nozzle 28 is started. If the sizing member 1 is rotated to the sizing position by counterclockwise rotation, the right air nozzle 29 is started. The rotation of the sizing member 1 and the blowing of the air nozzles 28, 29 are carried out simultaneously. Before the sizing member 1 rotates to perform the rotation action, the cleaning liquid 21 in the water tank 24 should be drained first to prevent pollution caused by the splashing of the cleaning liquid 21.

[0031] Figure 3 It is a schematic structural diagram of the second embodiment of the cleaning mechanism of a tipping paper sizing device provided by the present invention, as Figure 3As shown, the sink 24 has a water inlet 22 and a drain outlet 25; the cleaning mechanism further includes a water tank 31, a water inlet pump 32, a water inlet pipe 34, a water extraction pump 35, and a drain pipe 38; the water inlet of the sink 24 is connected to the output end of the water inlet pump 32 through the water inlet pipe 34, and the water tank 31 is connected to the input end of the water inlet pump 32 through a pipeline; the drain outlet 25 of the sink 24 is connected to the input end of the water extraction pump 35 through the drain pipe 38, and the water tank 31 is connected to the output end of the water extraction pump 35 through a pipeline. The water inlet pump 32 can extract the cleaning liquid 21 from the water tank 31 and pump it into the sink 24 through the water inlet pipe 34 and the water inlet 22, and the water extraction pump 35 can pump the water in the sink 24 back to the water tank 31. Thus, the cleaning liquid 21 in the water tank 31 and the sink 24 is circulated or replaced.

[0032] Preferably, as Figure 3 shown, a first one-way / check valve 33 is provided on the water inlet pipe 34 between the water inlet and the water inlet pump 32 to prevent the cleaning liquid 21 in the sink 24 from flowing back; a second one-way / check valve 36 is provided on the drain pipe 38 between the drain outlet 25 and the water extraction pump 35 to prevent the cleaning liquid 21 in the sink 24 from flowing by itself.

[0033] Preferably, as Figure 3 shown, a filter 37 is provided on the drain pipe 38 between the drain outlet 25 and the water extraction pump 35. To prevent foreign objects from blocking the inlet and outlet pipelines.

[0034] Preferably, as Figure 1 shown, the cleaning mechanism further includes a communicating vessel 27 connected to the bottom side of the sink 24, and a liquid level detection device (such as a liquid level sensor) is installed in the communicating vessel 27. Since the communicating vessel 27 is connected to the sink 24, the liquid level of the communicating vessel 27 is the liquid level of the sink 24. By providing the communicating vessel 27, it is convenient to detect the liquid level in the sink 24, so as to control the operation of the water inlet pump 32 or the water extraction pump 35 in real time according to the detection result of the liquid level detection device.

[0035] In some embodiments, as Figure 1 shown, a detachable filter screen 23 is provided at the bottom of the sink 24 to prevent foreign objects such as paper pieces and dried glue particles from blocking the drain outlet 25, and the detachable design also facilitates the replacement and cleaning of the filter screen 23.
