[0002] Adhesive tape has the advantages of strong adhesion and waterproof ability, and is widely used in various industries;

[0003] In the prior art, the roller-type glue coating equipment used in the production process of the tape uses a rubber roller to apply glue to the tape substrate. In this process, since the glue liquid is applied to the substrate by the rubber roller rotating in the glue collecting tank and then directly dried and shaped, it is easy to cause the glue liquid on the tape substrate to be uneven;

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Please refer to the attached Figure 1-3 , a transfer coating device for adhesive tape production, comprising:

[0024] The transfer tape unit 1 comprises a transfer tape unwinding roller 10, a glue collecting tank 11, a glue scraping assembly 12, a drying chamber 13 and a transfer tape winding roller 14, wherein the glue scraping assembly 12 is fixedly connected to the glue collecting tank 11;

[0025] The tape unit 2 includes a tape unwinding roller 20, a pressing assembly 21 and a tape winding roller 22 which are arranged in sequence;

[0026] Guide roller 3;

[0027] A plurality of guide rollers 3 are provided in the transfer tape portion 1 and the tape portion 2 ; the tape unwinding roller 20 is located between the drying chamber 13 and the extrusion assembly 21 , and the transfer tape winding roller 14 is located behind the extrusion assembly 21 .

[0028] When used specifically, (for ease of description, add transfer tape 4 and product tape 5, as shown in the attached Figure 1 The transfer tape 4 and the product tape 5 are provided with a matte surface and a glossy surface, both of which are sticky, and the matte surface is stickier than the glossy surface) After the transfer tape 4 is guided, its glossy surface contacts the glue transfer roller 112, and the glue transfer roller 112 applies the glue on the adhesive roller 110 to the glossy surface of the transfer tape 4. Then, when the transfer tape 4 passes through the scraper assembly 12, the glue exceeding the preset thickness is scraped off by the scraper plate 120, and the glue on the glossy surface of the transfer tape 4 is simply smoothed. Then, the transfer tape 4 enters the drying chamber 13 after being guided. In the process of passing through the entire drying chamber 13 , the glue on the smooth surface of the transfer tape 4 is dried to a semi-gel state, and then contacts the rough surface of the product tape 5 that is prevented from coming out of the tape unwinding roller 20 and is squeezed by a pair of squeezing components 20 to squeeze the uneven parts on the transfer tape 4 flat. At the same time, after the rough surface of the product tape 5 contacts the smooth surface of the transfer tape 4, due to the different viscosities, the glue will be transferred to the product tape 5. At least 4 groups of squeezing components 20 can maintain the entire squeezing contact process for a certain period of time to avoid the glue being unable to complete the purpose of complete transfer. Finally, the transferred product tape 5 and transfer tape 4 can be reeled up.

[0029] Specifically, the glue collecting tank 11 is provided with a glue roller 110, a first guide roller 111 and a glue transfer roller 112 which are movably connected thereto, the glue transfer roller 112 is located in the middle position of the glue roller 110 and the first guide roller 111, the glue roller 110 is located at the lower end of the glue transfer roller 112, and the glue roller 110 is in contact with the glue transfer roller 112, and the first guide roller 111 is against the glue roller 110; considering that the glue will have extremely poor smoothness if it is directly applied by the glue roller 110, the transfer-type application of the glue transfer roller 112 is adopted to improve the smoothness of the glue application, and the setting of the first guide roller 111 can ensure that the transfer tape 4 penetrates deep into the glue collecting tank 11 to avoid the occurrence of glue splash cleaning.

[0030] Specifically, the scraper assembly 12 includes a scraper plate 120, a pair of L-shaped plates 121 and a position adjustment plate 122. The pair of L-shaped plates 121 are fixedly connected to the two ends of the scraper plate 120, and the end of the L-shaped plate 121 away from the scraper plate 120 is provided with a slot 1210 and a fixing bolt 1211. The two ends of the position adjustment plate 122 pass through the two groups of the slots 1210 respectively, and the fixing bolt 1211 passes through the upper side of the L-shaped plate 121 and contacts the position adjustment plate 122, and the fixing bolt 121 1 is threadedly connected with the L-shaped plate 121; the thickness of the initial glue application of the transfer tape 4 is determined by the distance between the scraper plate 120 and the transfer tape 4, and the glue exceeding the thickness is scraped off, and the uneven glue can also be smoothed. At the same time, according to the thickness of the transfer tape 4, the position lock of the position adjustment plate 122 can be released by the fixing bolt 1211, and the distance between the transfer tape 4 and the scraper plate 120 is changed by adjusting the position of the position adjustment plate 122 in the slot 1210, so as to achieve the initial control of the glue thickness.

[0031] Specifically, the scraper 120 is located at the upper end of the first guide roller 111, and its side away from the first guide roller 111 is curved; the position of the scraper 120 is set to ensure that it can scrape off excess glue while smoothing the glue on the transfer tape 4.

[0032] Specifically, the extrusion assembly 21 is provided with at least four groups, including a connecting frame 210, two groups of outer sleeves 211, two groups of inner sleeves 212, two groups of springs 213 and an extrusion roller 214. One end of the inner sleeve 212 is sleeved in the outer sleeve 211. The spring 213 is located in the outer sleeve 211, and its two ends are respectively fixedly connected to the outer sleeve 211 and the inner sleeve 212. The two ends of the extrusion roller 214 are respectively rotatably connected to the ends of the two groups of inner sleeves 212 away from the outer sleeve 211. The outer plate 211 is fixedly connected to the connecting frame 210 at one end away from the inner plate 212; the extrusion of the transfer tape 4 and the product tape 5 is completed by setting a pair of extrusion components 21 in relative positions, and at least 4 groups can ensure that the transfer tape 4 and the product tape 5 have a certain contact extrusion distance. In this process, the remaining uneven areas on the transfer tape 4 can be squeezed flat by external force, and the transfer of glue can be achieved by the different viscosity characteristics of the smooth surface of the transfer tape 4 and the rough surface of the product tape 5.

[0033] Specifically, the transfer tape unit 1 and the tape unit 2 are provided with at least one set of motors.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
