Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum foil production, and specifically to an aluminum foil rewinder. Background Art
[0002] In the prior art, a rewinder is often used to rewind a large aluminum foil master roll into smaller sub-rolls. The working process of the rewinder includes feeding by a feeding roller, longitudinally cutting the master roll into smaller sub-rolls by a longitudinal cutting device, and winding the sub-rolls by a winding roller.
[0003] During the process of the longitudinal cutting device cutting the master roll, a large amount of aluminum foil debris will be generated. Due to reasons such as electrostatic adsorption, some debris will adhere to the surface of the aluminum foil. If the debris on the aluminum foil surface is not cleaned in time, the rewound sub-rolls will have wrinkles and other situations.
[0004] In the prior art, a blower is generally used to clean the debris, but the adhesion of the debris on the aluminum foil surface is relatively strong. If only by increasing the wind force of the blower to clean the debris, it is difficult to ensure that the debris on the aluminum foil surface has been completely cleaned before the winding roller winds, and it will increase the noise and energy consumption in the production workshop of the aluminum foil rewinder. Summary of the Utility Model
[0005] Aiming at the problem that it is difficult to thoroughly clean the debris attached to the aluminum foil surface by using a blower in the prior art, which affects the quality of aluminum foil products, the utility model provides an aluminum foil rewinder.
[0006] To solve the above technical problems, the utility model is solved by the following technical solutions:
[0007] An aluminum foil rewinder includes a mounting base, on which a feeding roller, a longitudinal cutting device and a winding roller are sequentially installed. A cleaning device is arranged between the longitudinal cutting device and the winding roller. The cleaning device includes a dust removing member arranged above the master roll, one end of the dust removing member abuts against the master roll, the cleaning device further includes a blower, a cavity is arranged inside the dust removing member, and a plurality of ventilation holes communicating with the cavity are arranged on one side of the dust removing member close to the longitudinal cutting device, and the blower is connected to the cavity.
[0008] In the utility model, the dust removing member can effectively scrape the debris on the surface of the master roll by abutting against the master roll; the air flow blown by the blower enters the cavity and then is discharged through the ventilation holes. The air flow can not only remove the debris on the master roll, but also timely clean the debris collected by the dust removing member, avoiding the problem that the dust removing efficiency of the dust removing member decreases due to debris accumulation.
[0009] Preferably, one end of the dust removing member away from the master roll extends outwards to form an extension end, and the ventilation holes are arranged on one side of the extension end close to the master roll.
[0010] In the present utility model, by arranging the ventilation holes at the extension end, the air flow direction of the ventilation holes is directed towards the ground. Compared with the air flow directions of other ventilation holes, this air flow direction can reduce the diffusion space of debris, and at the same time enable the debris on the mother roll to fall more quickly, which can more effectively avoid the situation of debris flying in the production workshop and protect the production environment of the production workshop.
[0011] Preferably, the dust removal member is arranged in a "V" shape, and the opening direction of the "V" shape of the dust removal member is consistent with the advancing direction of the mother roll.
[0012] In the present utility model, by arranging the dust removal member in a "V" shape, the debris will gradually move to both ends of the dust removal member along with the advancing direction of the mother roll, avoiding the accumulation of debris in the middle of the dust removal member, and enabling the blower to more effectively blow off the debris collected by the dust removal member.
[0013] Preferably, the ventilation holes are symmetrically arranged on both sides of the central axis of the extension end, and the ventilation holes are inclined in the extension end.
[0014] In the present utility model, through the ventilation holes inclined on the extension end, the air flow direction deviates towards both ends of the dust removal member, so that the blower can more quickly blow off the debris on the dust removal member.
[0015] Preferably, a recovery box with an open upper end is installed on the mounting seat, and the recovery box is arranged directly below the dust removal member.
[0016] In the present utility model, through the recovery box arranged directly below the dust removal member, the debris collected by the dust removal member can be collected more timely and effectively.
[0017] Preferably, a suction air pipe is connected to the inner cavity of the recovery box.
[0018] In the present utility model, through the suction air pipe connected to the recovery box, a negative pressure environment is formed inside the recovery box, and the debris can be more effectively collected into the recovery box. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0027] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model rather than limiting it.
[0028] In actual production, due to the excessively large master roll 160 of the aluminum foil, a rewinder is often used to rewind the aluminum foil master roll 160 into smaller sub-rolls. As Figure 1 shown, the rewinding process of the aluminum foil master roll 160 includes feeding through the feeding roller 120 on the mounting base 110, then cutting through the longitudinal cutting device 130, and the aluminum foil is then wound up by the coiling roller 140.
[0029] During the longitudinal cutting of the aluminum foil, due to static electricity and other reasons, a part of the debris will adhere to the surface of the aluminum foil. If not cleaned in time, it will affect the winding effect of the coiling roller 140. Therefore, a cleaning device 150 is provided between the longitudinal cutting device 130 and the coiling roller 140 to clean the debris on the master roll 160. The cleaning device 150 includes a dust removal member 1501 disposed above the master roll 160. The dust removal member 1501 scrapes off the debris on the surface of the master roll 160 by abutting against the master roll 160; the cleaning device 150 further includes a fan 1502. The fan air flow 180 blown by the fan 1502 passes through the cavity 1503 inside the dust removal member 1501 and then discharges from the ventilation hole 1504 on the dust removal member 1501, thereby blowing off the debris collected by the dust removal member 1501 and avoiding the accumulation of debris.
[0030] The debris collected by the dust removal member 1501 needs to be cleaned in time. Therefore, a recycling box 170 with an open upper end can be installed on the mounting base 110, and the recycling box 170 is disposed directly below the dust removal member 1501, thereby effectively collecting the debris collected by the dust removal member 1501 in a timely manner.
[0031] The air flow at the rewinding processing site is relatively disordered, and debris is easily affected by the air flow and moves; therefore, in order to improve the recovery effect of the recovery box 170, an air suction pipe 1701 can be connected to the inner cavity of the recovery box 170, so that a negative pressure environment is formed inside the recovery box 170 through the air suction pipe 1701.
[0032] In view of the possible problems that may occur during the specific use of the dust removal member 1501, the present utility model designs various structures of the dust removal member 1501.
[0033] Embodiment 1
[0034] When the blower air flow 180 blows off debris, it will cause the debris to fly in the production workshop, affecting the environment of the production workshop. Therefore, we provide a structure of the dust removal member 1501, as Figure 2 and Figure 3 shown, one end of the dust removal member 1501 away from the master roll 160 extends outward to form an extended end 1505, and the ventilation holes 1504 are arranged on the side of the extended end 1505 close to the master roll 160.
[0035] This setting makes the air flow direction of the blower 180 downward, thereby reducing the diffusion space of the debris, and at the same time enabling the debris to fall faster, more effectively avoiding the situation of debris flying in the production workshop and protecting the production environment of the production workshop.
[0036] Embodiment 2
[0037] Conventional dust removal members 1501 are generally set in a cuboid shape, and debris is easily accumulated in the middle of the dust removal member 1501 of this shape; when the blower air flow 180 of the blower 1502 is small, it is difficult to remove the debris accumulated in the middle of the dust removal member 1501. Although increasing the blower air flow 180 of the blower 1502 can blow off the debris accumulated in the middle of the dust removal member 1501, it will aggravate the flying of the debris and affect the environment of the production workshop. According to this situation, as Figure 4 shown, we set the dust removal member 1501 in a "V" shape, and the opening direction of the "V" shape of the dust removal member 1501 is consistent with the traveling direction of the master roll 160.
[0038] The debris will gradually move to both ends of the dust removal member 1501 along with the traveling direction of the master roll 160, avoiding the accumulation of debris in the middle of the dust removal member 1501, so that the blower 1502 can use a smaller blower air flow 180 to blow off the debris collected by the dust removal member 1501.
[0039] Embodiment 3
[0040] For the dust removal member 1501 provided in Embodiment 1 and Embodiment 2, if the ventilation holes 1504 are directly vertically arranged in the extended end 1505, as Figure 5The blower air flow 180 blown out from the ventilation holes 1504 will first reach the aluminum foil surface and then spread around. The blower air flows 180 of multiple ventilation holes 1504 will disturb each other, affecting the cleaning effect of the blower air flow 180 on the dust removal member 1501.
[0041] As Figure 6 shown, we provide a structure of the dust removal member 1501. By symmetrically arranging the ventilation holes 1504 on both sides of the central axis of the extension end 1505 and obliquely arranging the ventilation holes 1504 in the extension end 1505, the disturbance effect between the blower air flows 180 of multiple ventilation holes 1504 is reduced, enabling the blower 1502 to clean the dust removal member 1501 with a smaller blower air flow 180.
[0042] In summary, the above are only the preferred embodiments of this embodiment. All equivalent changes and modifications made according to the scope of the patent application of this embodiment shall fall within the scope covered by the patent of this embodiment.
