Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label production technology, and in particular to a self-cleaning transfer roller for self-adhesive labels. Background Technology

[0002] Self-adhesive labels are a type of composite material with built-in adhesive. During production, they require the use of rollers for transfer, winding, and other processes.

[0003] During the transfer and production of self-adhesive labels, the adhesive layer of the self-adhesive label is sandwiched between the face stock and the backing paper. The roller only contacts the backing paper and does not adhere to the adhesive. However, if adhesive overflow occurs at the edge of the material or the backing paper is damaged, the adhesive will adhere to the outside of the roller, affecting subsequent production.

[0004] To address the aforementioned issues, a cell electrode film wrapping machine and its roller surface cleaning device are disclosed in application number 201210284707.0. In this device, a scraper is used to clean the roller surface. However, the scraper is fixed in its installation position and is only applicable to rollers located at that position, resulting in a narrow range of application. Therefore, improvements are needed. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Reference Figures 1-3 According to an embodiment of the present invention, a self-cleaning transfer roller for self-adhesive labels includes a roller body 11, the roller body 11 including a roller core 21 and a roller 22 fixed outside the roller core 21, a vertical plate 13 rotatably connected to the roller core 21 on both sides of the roller 22, a control plate 14 installed between the two vertical plates 13, and a lifting assembly for controlling the distance of the control plate 14 relative to the roller 22, and a locking assembly for locking the angle of the vertical plate 13.

[0028] When the roller 11 is installed in the frame to transfer the self-adhesive, the roller 11 can be driven to rotate by the motor on the frame. At this time, under the control of the locking component, the vertical plate 13 can be locked at an angle so as not to rotate with the roller 11.

[0029] Furthermore, the controlled plate 14 is equipped with a scraper 15, which is obliquely arranged to form an acute angle with the surface of the roller 22 that can be adhered to. When it is necessary to scrape the curved surface of the roller 22, the lifting assembly controls the controlled plate 14 and the scraper 15 to move closer to the roller 22 until the roller 22 is adhered to the curved surface of the roller 22. Then, when the roller 22 rotates, the scraper 15 can scrape and clean the surface of the roller 22.

[0030] The lifting assembly includes a horizontal plate 16 connected between the two vertical plates 13. A cylinder 17 is fixed on the horizontal plate 16, and the piston rod inside the cylinder 17 passes through the horizontal plate 16 and is connected to the side of the controlled plate 14. That is, the cylinder 17 can control the distance between the controlled plate 14 and the scraper 15 relative to the roller 22, and the controlled plate 14 is slidably connected to the two vertical plates 13 so that the movement of the controlled plate 14 is stable.

[0031] In one embodiment of the locking assembly, the vertical plate 13 can be directly connected to the frame by fasteners to lock the angle.

[0032] In the second embodiment of the locking assembly, in order to facilitate the adjustment of the angle of the vertical plate 13, the locking assembly includes a pin 18, which is threaded into the vertical plate 13. Each vertical plate 13 is provided with two symmetrically distributed pins 18, and one end of each pin 18 is equipped with a cap. In addition, it also includes two mounting plates 19 distributed on the left and right. The two ends of the roller core 21 are respectively rotatably connected to the two mounting plates 19. The side of the mounting plate 19 is provided with locking holes 20 that are adapted to the pins 18. The locking holes 20 are evenly distributed around the axis of the roller core 21, and the mounting plate 19 is provided with mounting holes for installation in the frame.

[0033] In this embodiment, the mounting plate 19 is fixed inside the frame, and the roller core 21 can extend outside the mounting plate 19 to connect with the motor on the frame and be driven.

[0034] Furthermore, when it is necessary to adjust the angle of the vertical plate 13, the operator can rotate the cap to rotate the pin 18, thereby disengaging the pin 18 from the locking hole 20. At this time, the vertical plate 13 is unlocked and the angle can be adjusted at will. After the adjustment is completed, the operator can rotate the cap to re-insert the pin 18 into other locking holes 20 to complete the locking of the angle of the vertical plate 13.

[0035] It should be noted that when the roller 22 is in operation, its surface will be covered with self-adhesive. After the vertical plate 13 is installed, the position of the roller 22 corresponding to the scraper 15 should be an area not covered by self-adhesive, so as to avoid interference between the scraper 15 and the self-adhesive when cleaning.

[0036] Furthermore, in a third embodiment of the self-cleaning transfer roller for self-adhesive labels, in order to prevent the dirt scraped off by the scraper 15 from falling back onto the roller 22, a negative pressure groove 31 is provided in the controlled plate 14, and the negative pressure groove 31 is directly opposite the side of the scraper 15 away from the roller 22, so that the dirt on the scraper 15 will be directly sucked away.

[0037] Specifically, the upper side of the controlled plate 14 is provided with an air intake that is connected to the negative pressure groove 31, and the horizontal plate 16 is provided with a through hole. The air intake and the through hole are connected by a corrugated pipe, and the through hole is connected to a negative pressure cleaning device (such as a vacuum cleaner) by a flexible hose.

[0038] By using the central hole and the corrugated pipe, compared to the solution of directly connecting the hose to the air inlet, the service life of the hose can be extended, interference between the hose and the horizontal plate 16 can be avoided when the controlled plate 14 moves outward, and the negative pressure cleaning device should work when the scraper 15 presses against the roller 22 so that suction is generated in the negative pressure groove 31.

[0039] It should also be noted that the adhesive scraped off by the scraper 15 should have solidified to avoid remaining in the negative pressure groove 31.

[0040] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
