Description

Technical Field

[0001] This utility model relates to the field of cigarette machinery and equipment technology, and more specifically, to a dust removal device for a transparent paper cutting roller. Background Technology

[0002] In the FOCKE408 model, the cutting of the carton's cellophane is accomplished by a cutting roller. The cellophane cutter consists of a moving blade and a fixed blade, whose function is to cut the cellophane to a fixed length for easy packaging. During actual production, some white powder adheres to the surface of the cutting roller. This powder comes from the cellophane manufacturer and its purpose is to add a layer of white powder (metallization film) to the surface. This metallization film can be aluminum or other metals. Its purpose is to reduce the surface resistivity of the cellophane, prevent static electricity accumulation, and give the cellophane a good appearance and texture, while maintaining the original excellent properties of the cellophane, such as transparency, mechanical strength, and folding resistance.

[0003] However, during production, the white powder adhering to the surface of the cutting roller is drawn into the inside of the cutting roller and the suction conveying pipe by the negative pressure suction, thus clogging the negative pressure suction and reducing the suction pressure. The reduced negative pressure suction will also cause the transparent paper adsorbed on the cutting roller to shift, resulting in quality defects in the finished cigarette packs such as crooked folds, wrinkles, uneven stitching, and misaligned seams.

[0004] Therefore, how to provide a dust removal device for transparent paper cutting rollers has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0029] like Figures 1 to 3 As shown, this utility model embodiment provides a dust removal device for a transparent paper cutting roller. The cutting roller 4 is fixed on the fixed plate 5 of the packaging machine. The fixed plate 5 is connected to a support bracket 6 and a turret mold box 7.

[0030] Specifically, the cutting roller 4 has multiple suction holes 41 so that the transparent paper can be adsorbed onto the cutting roller 4. A transparent paper conveying roller 8 is provided on one side of the cutting roller 4 to convey the transparent paper onto the cutting roller 4. A packaging turret 9 is provided on the other side of the cutting roller 4, and the turret mold box 7 is located above the packaging turret 9.

[0031] The dust removal device includes a fixing component 1, a negative pressure component 2, and a cleaning component 3; the fixing component 1 is fixed on the support bracket 6 and is located above the cutting roller 4.

[0032] Negative pressure component 2 and cleaning component 3 are both mounted on fixed component 1. Negative pressure component 2 is located downstream of cleaning component 3. Cleaning component 3 includes felt 31 and felt seat 32. The felt seat 32 is provided with a groove. The first end of felt 31 is located in the groove, and the second end of felt 31 is in contact with the outer peripheral wall of cutting roller 4.

[0033] Specifically, the fiber structure of the felt 31 has a certain elasticity and adsorption. With appropriate force and angle, the felt 31 can remove powder and debris from the surface of the cutting roller 4. The felt 31 completes a full roller cleaning for each rotation of the cutting roller 4.

[0034] In addition, when replacing the felt 31, simply pull the felt 31 out of the groove.

[0035] During operation, as the cutting roller 4 rotates, the cutting roller 4 and the felt 31 move relative to each other. At this time, the felt 31 comes into contact with the cutting roller 4, pushing the powder and debris on the surface of the cutting roller 4 to the negative pressure component 2. The negative pressure component 2 absorbs the powder and debris, thus completing the cleaning of the powder and debris.

[0036] This invention fixes a fixed component 1 on a support bracket 6, with the fixed component 1 positioned above the cutting roller 4. Both the negative pressure component 2 and the cleaning component 3 are mounted on the fixed component 1, with the negative pressure component 2 downstream of the cleaning component 3. A groove is provided on the felt seat 32, with the first end of the felt 31 positioned within the groove and the second end of the felt 31 contacting the outer peripheral wall of the cutting roller 4. During operation, as the cutting roller 4 rotates, relative movement occurs between the cutting roller 4 and the felt 31. At this time, the felt 31 contacts the cutting roller 4, pushing powder and debris from the surface of the cutting roller 4 to the negative pressure component 2. The negative pressure component 2 absorbs the powder and debris, preventing them from entering the suction hole 41 of the cutting roller 4 and causing blockage of the suction. This cleans the cutting roller 4, ensuring stable negative pressure suction and solving problems such as skewed transparent paper transfer, wrinkled transparent paper wrapping, uneven threading, and misaligned seams.

[0037] In one embodiment of the transparent paper cutting roller dust removal device of this utility model, such as Figure 2As shown, in order to improve the cleaning effect of the felt 31, the second end of the felt 31 is set as an arc-shaped structure. The diameter of the arc-shaped structure at the second end of the felt 31 is equal to or slightly larger than the diameter of the cutting roller 4, so that the felt 31 can concentrate all the powder and debris on the surface of the cutting roller 4 under the cleaning component 3, thereby enabling the cleaning component 3 to absorb the powder and debris.

[0038] In one embodiment of the transparent paper cutting roller dust removal device of this utility model, such as Figure 1 and Figure 2 As shown, the negative pressure assembly 2 includes a dust suction hood 21, a negative pressure air pipe, and a connector 22. The connector 22 is located at the top of the dust suction hood 21, which is located above the cutting roller 4. The first end of the negative pressure air pipe is connected to the connector 22, and the second end of the negative pressure air pipe is used to connect to an external negative pressure source.

[0039] This utility model sets the connector 22 at the top of the dust collection hood 21, which is located above the cutting roller 4. The first end of the negative pressure air pipe is connected to the connector 22, and the second end of the negative pressure air pipe is used to connect to an external negative pressure source. The external negative pressure source provides negative pressure to the negative pressure air pipe, so that the dust collection hood 21 can absorb powder and debris, thereby achieving the cleaning of powder and debris.

[0040] In one embodiment of the transparent paper cutting roller dust removal device of this utility model, such as Figure 2 As shown, the length of the dust hood 21 and the length of the felt 31 are less than or equal to the length of the cutting roller 4.

[0041] In this embodiment, there are multiple negative pressure air pipes and connectors 22. The connectors 22 are spaced apart along the length of the dust collection hood 21. The multiple negative pressure air pipes are connected to the multiple connectors 22 respectively to improve cleaning efficiency.

[0042] In one embodiment of the transparent paper cutting roller dust removal device of this utility model, such as Figure 1 and Figure 2 As shown, the fixing component 1 includes a connecting plate 11, a mounting plate 12 and a plurality of fixing bolts 13. The connecting plate 11 is fixed on the support bracket 6, the mounting plate 12 is perpendicularly connected to the connecting plate 11, and the plurality of fixing bolts 13 pass through the mounting plate 12 and are respectively connected to the felt seat 32 and the dust collection cover 21.

[0043] Specifically, the connecting plate 11 is fixed to the support bracket 6 by bolts.

[0044] This utility model fixes the connecting plate 11 on the support bracket 6, and the mounting plate 12 is vertically connected to the connecting plate 11. Multiple fixing bolts 13 pass through the mounting plate 12 and are respectively connected to the felt seat 32 and the dust collection hood 21, thereby enabling the felt seat 32 and the dust collection hood 21 to be stably installed on the mounting plate 12, ensuring the stability of the transparent paper cutting roller dust removal device of this utility model.

[0045] In one embodiment of the transparent paper cutting roller dust removal device of this utility model, such as Figures 1 to 3 As shown, the mounting base has multiple connection holes.

[0046] The felt base 32 is provided with a first mounting hole 33, and the dust cover 21 is provided with a second mounting hole. Multiple fixing bolts 13 pass through multiple connecting holes and are threadedly connected to the first mounting hole 33 and the second mounting hole.

[0047] Specifically, there are three first mounting holes 33 and three second mounting holes, and six fixing bolts 13.

[0048] This utility model provides a first mounting hole 33 on the felt base 32 and a second mounting hole on the dust collection cover 21. Multiple fixing bolts 13 pass through multiple connecting holes and are threadedly connected to the first mounting hole 33 and the second mounting hole, thereby fixing the dust collection cover 21 and the felt base 32 onto the mounting plate 12. The fixing bolts 13 can also be used to adjust the distance between the dust collection cover 21 and the felt 31 and the cutting roller 4, thereby improving the cleaning efficiency of powder and debris on the surface of the cutting roller 4.

[0049] In one embodiment of the transparent paper cutting roller dust removal device of this utility model, such as Figures 1 to 3 As shown, the fixing component 1 also includes a spring 14, which is respectively sleeved on a plurality of fixing bolts 13.
