Description

Technical Field

[0001] The utility model relates to the technical field of roller dust removal, in particular to a winding device and vacuum coating equipment. Background Art

[0002] Vacuum coating equipment consists of a winding unit and an evaporation unit. The winding unit includes a main roller for conveying PET film, while the evaporation unit is used to evaporate and coat the PET film. During the evaporation process, the PET film is burned through and falls onto the main roller for pre-cooling, forming metal particles that adhere to the main roller. During subsequent winding of the PET film, metal particles and other impurities on the main roller can cause perforations or pits in the PET film.

[0003] In order to solve the above problems, in the existing technology, a scraper blade is generally in contact with the outer peripheral surface of the main roller. During the rotation of the main roller, the scraper blade scrapes off impurities such as metal particles on the outer peripheral surface of the main roller. The metal particles fall under the action of gravity, but some tiny metal particles cannot fall because the gravity is too light. Utility Model Content

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] The present invention provides a winding device and vacuum coating equipment. The vacuum coating equipment includes the winding device and an evaporation device 100 provided in this embodiment. The evaporation device 100 is used to perform evaporation coating on a PET film. The winding device is protected from impurities such as metal particles, thereby preventing defects such as perforations or pits from forming on the PET film during winding.

[0042] like Figure 1-Figure 5 As shown, the winding device includes a bracket 1, a main roller 2, a scraper assembly 3, and a dust removal assembly 4. The main roller 2 is rotatably connected to the bracket 1. During the evaporation coating process of the evaporation device 100, impurities such as metal particles may adhere to the outer circumference of the main roller 2. To remove these impurities, the scraper assembly 3 includes a scraper blade 31. The scraper blade 31 is capable of contacting the outer circumference of the main roller 2 and scraping away metal particles and other impurities from the outer circumference of the main roller 2 as the main roller 2 rotates. It is understood that when removing impurities, the PET film wrapped around the outer circumference of the main roller 2 is also removed.

[0043] Due to the presence of tiny particles in impurities such as metal particles, when the scraper blade 31 scrapes off the impurities, the tiny particles cannot fall off by gravity, but are arranged in a line and attached to the outer peripheral surface of the main roller 2 under the action of the scraper blade 31. In order to solve the above problem, the dust removal component 4 includes a dust removal drive 41 and a dust removal roller 42. The dust removal drive 41 is arranged on the bracket 1, and the dust removal roller 42 is connected to the output end of the dust removal drive 41. After the scraper blade 31 is separated from the outer peripheral surface of the main roller 2, the dust removal drive 41 can drive the dust removal roller 42 to abut the outer peripheral surface of the main roller 2, and the dust removal roller 42 can rotate with the main roller 2 and can adhere the impurities scraped by the scraper blade 31 and in a linear shape still attached to the outer peripheral surface of the main roller 2 to the dust removal roller 42, so as to completely remove the impurities on the main roller 2.

[0044] The winding device first scrapes impurities from the outer peripheral surface of the main roller 2 by setting a scraper blade 31, and after the scraper blade 31 is separated from the main roller 2, the dust removal drive 41 drives the dust removal roller 42 to abut the outer peripheral surface of the main roller 2. When the dust removal roller 42 rotates following the main roller 2, impurities on the main roller 2 that are not removed by the scraper blade 31 can adhere to the dust removal roller 42, solving the problem of tiny particles unable to fall off, ensuring the cleanliness of the main roller 2, and avoiding affecting the film.

[0045] Optionally, the dust removal roller 42 is made of silicone. By using silicone to make the dust removal roller 42, impurities can be adhered.

[0046] In this embodiment, the bracket 1 includes two vertical plates 11 , and the main roller 2 is rotatably disposed between the two vertical plates 11 ; in order to enhance the stability of the two vertical plates 11 , a connecting roller 12 is further disposed between the two vertical plates 11 .

[0047] Along the rotation direction of the main roller 2, the scraper blade 31 is located upstream of the dust removal roller 42, as shown in FIG. Figure 1 As shown, when the main roller 2 rotates clockwise, after the scraper blade 31 scrapes off impurities on the outer peripheral surface of the main roller 2, the main roller 2 rotates a smaller angle, and the dust removal roller 42 can adhere to the impurities that are not removed by the scraper blade 31, with higher adhesion efficiency and more reasonable structural design.

[0048] Alternatively, as Figure 4 As shown, in the same cross section, the angle a between the line connecting the center of the main roller 2 and the center of the dust removal roller 42 and the Y axis is 0°-45°. This structure allows the impurities attached to the outer surface of the main roller 2 that are not removed by the scraper blade 31 to adhere to the dust removal roller 42 before they are scattered when the main roller 2 rotates.

[0049] Alternatively, as Figure 2-Figure 3As shown, the winding device further includes a mounting frame 5, which is arranged corresponding to the two vertical plates 11 of the bracket 1, that is, two mounting frames 5 are provided, and the two mounting frames 5 are respectively connected to the two vertical plates 11. Two dust removal drive members 41 are provided, and the two dust removal drive members 41 are respectively connected to the two mounting frames 5. The two ends of the scraper assembly 3 are respectively connected to the two mounting frames 5. This structure is simplified by mounting both the dust removal drive member 41 and the scraper assembly 3 on the mounting frame 5.

The scraper driving member can drive the scraper blade 31 to rotate and make the scraper blade 31 abut against the outer peripheral surface of the main roller 2, so that the scraper blade 31 can be rotated by the scraper driving member to abut against the main roller 2, or be separated from the main roller 2.

Among the two groups of airbags, one group of airbags is inflated to drive the scraper blade 31 to rotate and abut against the outer peripheral surface of the main roller 2, and the other group of airbags is inflated to drive the scraper blade 31 to separate from the main roller 2.

[0053] When the scraper blade 31 abuts against the main roller 2, in order to be able to adjust the angle of the scraper blade 31, a rotating shaft 331 is provided on both end surfaces of the first plate of the scraper mounting plate 33, and the two scraper fixing blocks 32 are both provided with a third mounting hole. The rotating shaft 331 is set in the third mounting hole, and the rotating shaft 331 can be rotated and adjusted relative to the third mounting hole. The third fastener can fix the rotating shaft 331 after rotation adjustment in the third mounting hole.

[0054] In this embodiment, the third fastener can be selected as a screw. The scraper fixing block 32 is provided with a threaded hole connected to the third mounting hole. The third fastener is screwed into the threaded hole and can abut against the rotating shaft 331 to fix the rotating shaft 331 in the third mounting hole.

[0055] Alternatively, as Figure 5 Shown and combined Figure 3As shown, the mounting frame 5 includes a main structure 51 and a transverse connecting plate 52. One end of the main structure 51 is connected to the vertical plate 11 of the bracket 1, and the transverse connecting plate 52 is provided at the other end of the main structure 51. The scraper fixing block 32 is connected to the transverse connecting plate 52, and the scraper fixing block 32 can be moved and adjusted along the X-axis to adjust the distance between the scraper blade 31 and the main roller 2 along the X-axis to increase the contact force of the scraper blade 31. The X-axis and the Y-axis are perpendicular to each other.

[0056] Furthermore, the transverse connecting plate 52 is provided with a second elongated hole 521 extending along the X-axis direction.

The upper connecting portion 321 of the scraper fixing block 32 is provided with a second mounting hole. A second fastener 522 can be inserted into the second mounting hole and the second elongated hole 521 to connect the scraper fixing block 32 and the transverse connecting plate 52. The second fastener 522 moves in the second elongated hole 521 to allow the scraper fixing block 32 to be moved and adjusted along the X-axis direction, thereby allowing the scraper fixing block 32 to drive the scraper blade 31 to be moved and adjusted via the scraper mounting plate 33.

[0057] In order to realize the connection of the dust removal drive member 41, the mounting frame 5 also includes a vertical connecting plate 53, which is fixedly connected to the horizontal connecting plate 52. The dust removal drive member 41 is connected to the vertical connecting plate 53, and the horizontal connecting plate 52 is provided with a notch for avoiding the dust removal drive member 41, and the dust removal drive member 41 can move along the X-axis direction to adjust the distance between the dust removal roller 42 and the main roller 2 along the X-axis direction.

[0058] Furthermore, the vertical connecting plate 53 is provided with a first elongated hole 531 extending along the X-axis direction, and the dust removal drive member 41 is provided with a first mounting hole. A first fastener is inserted into the first mounting hole and the first elongated hole 531 to connect the dust removal drive member 41 to the vertical connecting plate 53.

In this embodiment, two first elongated holes 531 and two second mounting holes are provided, one corresponding to each other.
