Oil cloth paper is adhered to the self-adhesive layer on the back of the self-adhesive label to maintain the stickiness of the adhesive layer. The self-adhesive label is printed through a coating device to print the required text and pattern on the label. A large number of self-adhesive labels can be produced quickly. A coating device is often installed on the coating equipment to control the temperature when coating the label.
[0003] In the prior art, the coating device applies silicon or glue to the self-adhesive label through a roller, and conveys the self-adhesive label through another roller, so that the self-adhesive label is continuously coated with silicon or glue during the movement.
[0004] However, with this type of coating equipment, the self-adhesive label may deviate along the guide roller during the transmission process, resulting in the self-adhesive label position not corresponding to the coating position of the coating equipment, resulting in part of the self-adhesive label not being coated.

[0028] Example 1
[0029] This embodiment proposes a temperature-controlled coating device for uniformly coating self-adhesive labels with silicon glue, such as Figure 1 As shown, it includes two symmetrically arranged mounting plates 1, a vertical plate 2 is fixedly installed on the top of the mounting plate 1, and the two vertical plates 2 are rotatably connected to the same coating roller 3 on the opposite side, and the coating roller 3 is provided with a self-adhesive label; the two vertical plates 2 are rotatably connected to the opposite side with multiple driving rollers, the self-adhesive labels are transported by the driving rollers, and then the self-adhesive labels are coated with silicon or glue by the coating roller 3.
[0030] like Figure 2 and 3 As shown, the temperature-controlled coating equipment also includes a guide assembly 4, which includes a telescopic assembly, a sleeve 43, an insertion rod 44, a contact ring 45 and a contact switch 47. The sleeve 43 is arranged at the end of the telescopic assembly, the inner wall of the sleeve 43 is slidably connected to the insertion rod 44, the contact ring 45 is fixedly installed at the end of the insertion rod 44, and the contact switch 47 is fixedly installed inside the sleeve 43 and on the extension line of the end of the insertion rod 44; the telescopic assembly is fixedly installed on the side of the upright plate 2, the contact switch 47 is electrically connected to the telescopic assembly through the controller, and the contact ring 45 contacts the self-adhesive label on the side away from the insertion rod 44.
[0031] The sleeve 43 is moved by extending the telescopic assembly, and the sleeve 43 drives the contact ring 45 and the insertion rod 44 to move synchronously. When the contact ring 45 contacts the self-adhesive label, as the sleeve 43 moves, the insertion rod 44 is retracted into the sleeve 43, and its end contacts the contact switch 47. At this time, the contact switch 47 stops the movement of the telescopic assembly through the controller. The contact ring 45 contacts the self-adhesive label to determine the overall width of the self-adhesive label, so that the two contact rings 45 position and guide the self-adhesive label to prevent the self-adhesive label from being offset along the coating roller 3. This prevents the self-adhesive label position from not corresponding to the coating position of the coating device, resulting in invalid coating and uneven coating.
[0032] like Figure 3As shown, a return spring 46 is elastically connected between the end of the insertion rod 44 and the sleeve 43, and the sleeve 43 and the contact ring 45 are both sleeved on the coating roller 3. After the contact ring 45 contacts the self-adhesive label, the insertion rod 44 moves into the sleeve 43 and compresses the return spring 46. When the contact ring 45 is not subjected to force, the return spring 46 uses its elasticity to return the insertion rod 44 and the contact ring 45 to their original positions.
[0033] The coating roller 3 has a convex strip 6 fixedly mounted on the curved surface near the end, and the inner wall of the sleeve 43 has a groove 48, and the convex strip 6 slides in the groove 48 of the inner wall of the sleeve 43. The coating roller 3 drives the sleeve 43 to rotate synchronously through the convex strip 6, that is, the contact ring 45 moves synchronously with the self-adhesive label.
[0034] The telescopic assembly includes a docking ring 41 and an electric push rod 42. The end of the electric push rod 42 is fixedly mounted on the side of the upright plate 2. The other end of the electric push rod 42 is fixedly connected to the docking ring 41. The side of the docking ring 41 away from the electric push rod 42 is rotatably connected to the sleeve 43. The electric push rod 42 is electrically connected to the contact switch 47. The electric push rod 42 extends to move the sleeve 43. The above steps are performed by rotating the electric push rod 42 and the sleeve 43 to prevent the sleeve 43 from getting stuck with the electric push rod 42 when the coating roller 3 rotates.
[0035] In this embodiment, the sleeve 43 is moved by extending the electric push rod 42, so that the contact ring 45 contacts the self-adhesive label, the contact ring 45 and the insertion rod 44 move toward the sleeve 43, and the end of the insertion rod 44 contacts the contact switch 47. At this time, the contact switch 47 stops the telescopic component from moving through the controller, and the contact ring 45 contacts the self-adhesive label to determine the overall width of the self-adhesive label, so that the two contact rings 45 position and guide the self-adhesive label to avoid the self-adhesive label from being offset along the coating roller 3. In this way, the self-adhesive labels of different widths can be adapted to prevent the position of the self-adhesive label from not corresponding to the coating position of the coating device, resulting in invalid coating and uneven coating.
[0036] Example 2
[0037] Based on Example 1, this example proposes a temperature-controlled coating device for uniformly coating self-adhesive labels with silicon glue, such as Figure 1 and 4 As shown, the cleaning assembly 5 is also included. The cleaning assembly 5 includes a guide rod 51, a first scraper 52 and a second scraper 54. The two ends of the guide rod 51 are respectively installed on the sides of the two upright plates 2. A plurality of guide rods 51 are provided, two of which form a group. The first scraper 52 and the second scraper 54 slide on the two guide rods 51 in a group respectively. By adjusting the positions of the first scraper 52 and the second scraper 54 to adapt to the coating width of the self-adhesive label, the coating roller 3 is cleaned to avoid the accumulation of glue or silicon residue on the coating roller 3, which leads to uneven coating of glue or silicon.
[0038] The guide rod 51 is located just above the coating roller 3. The first scraper 52 and the second scraper 54 are provided with arc surfaces at their bottoms, which are in contact with the coating roller 3 and have the same arc. The arc surfaces at the bottoms of the first scraper 52 and the second scraper 54 are used to clean the arc surface of the coating roller 3.
[0039] like Figure 4 As shown, the ends of the first scraper 52 and the second scraper 54 are fixedly mounted with a docking block 53, the cross section of the docking block 53 adopts an I-shaped structure, the contact ring 45 is located at the I-shaped opening of the docking block 53, and the positions of the first scraper 52 and the second scraper 54 are staggered. When the position of the contact ring 45 changes, the positions of the first scraper 52 and the second scraper 54 also change with the contact ring 45, that is, when the two contact rings 45 adapt to the width of the self-adhesive label, the second scraper 54 and the first scraper 52 also adapt to the width of the self-adhesive label.
[0040] In this embodiment, when the position is adjusted by the contact ring 45 to adapt to the width of the self-adhesive label, the contact ring 45 drives the electric push rod 42 and the insertion rod 44 to move. When the distance between the two contact rings 45 changes, the electric push rod 42 and the insertion rod 44 change accordingly to adapt to the distance between the two contact rings 45, so that the electric push rod 42 and the contact ring 45 can always contact the coating roller 3 for cleaning.
[0041] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
