Technical Field

[0001] The utility model relates to the technical field of coiled material coating, in particular to a polymer self-adhesive coating device. Background Art

[0002] Self-adhesive coatings are self-adhesive coatings that are applied to the surface of a material. When they come into contact with other surfaces, they adhere automatically and create a durable bond without the need for additional glue or adhesives. Self-adhesive coatings are usually made of special adhesives or polymer materials.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1: A polymer self-adhesive coating device, such as Figure 1 and Figure 3 As shown, it includes a coating pool 1 and a drying table 7. A sliding frame 2 is slidably installed on the side of the coating pool 1 away from the drying table 7. A plurality of rollers 3 are provided on the bottom surface of the sliding frame 2. A support frame 4 is fixedly installed on the sliding frame 2. When in use, the base cloth to be coated is rolled up on the winding shaft, and the material rolled up with the base cloth is supported and held by the support frame 4. A guide roller 5 is movably installed on the side of the upper edge of the coating pool 1 close to the support frame 4 through a rotating shaft, and a left-right symmetrical retaining ring 50 is fixedly sleeved on the guide roller 5.

[0029] like Figure 2 As shown, two groups of scraper rollers 15 are rotatably installed on the side of the upper edge of the coating pool 1 away from the guide roller 5, and the two groups of scraper rollers 15 are correspondingly distributed up and down, and the reel with the base cloth rolled up is placed on the support frame 4, and one end of the base cloth is pulled through the guide roller 5 to extend into the coating pool 1 through the external traction mechanism, and one end of the base cloth is sequentially extended to the side close to the drying table 7 through the guide roller 5 and the scraper roller 15, and the coating pool 1 is provided with a base cloth extrusion mechanism 13 for controlling the self-coating of the base cloth;

[0030] like Figure 4As shown, the base fabric extrusion mechanism 13 includes two groups of elliptical plates 131, and the top surface of the coating pool 1 is fixedly installed with left-right symmetrical connecting ears, and a connecting sleeve 130 is rotatably installed between the two groups of connecting ears. The two groups of elliptical plates 131 are fixedly sleeved on the connecting sleeve 130, and multiple groups of extrusion rollers 132 are rotatably installed between the two groups of left-right symmetrical elliptical plates 131. The multiple groups of extrusion rollers 132 are rotatably installed on one side of the elliptical plate 131 close to the edge. A hand wheel 14 is rotatably installed on the connecting ear, and the hand wheel 14 is fixedly connected to the connecting sleeve 130. By rotating the hand wheel 14, the hand wheel 14 controls the rotation of the base fabric extrusion mechanism 13. The inside of the coating pool 1 stores a polymer self-adhesive coating, and the base fabric extrusion mechanism 13 is used to separate the polymer self-adhesive coating. The base fabric in the middle of the coating pool 1 is squeezed downward to make the base fabric contact with the polymer coating in the coating pool 1, so that the polymer coating is evenly dipped on the upper and lower sides of the base fabric, thereby completing the self-adhesive coating of the base fabric. The base fabric with the coating is continuously pulled outward by two sets of scraper rollers 15. As the base fabric completes the self-adhesive coating operation, the polymer coating in the coating pool 1 becomes less and less. At this time, the hand wheel 14 is rotated to make the hand wheel 14 and the base fabric squeezing mechanism 13 rotate eccentrically, so that the base fabric squeezing mechanism 13 can conveniently squeeze the base fabric distributed in the coating pool 1, so as to avoid the reduction of the polymer coating in the coating pool 1, which makes it difficult for the base fabric to be completely dipped in the coating. The scraper roller 15 is provided to conveniently scrape off the excess coating on the base fabric.

[0031] Embodiment 2, based on embodiment 1, as Figure 1 and 2 As shown, the coating pool 1 and the drying table 7 are fixedly connected by a connecting platform 6, and the top surface of the connecting platform 6 is inclined. A drying chamber 10 is provided on the drying table 7, and a plurality of discharge ports 11 are provided on the top surface of the drying chamber 10. A feeding port 12 is provided on one side of the drying chamber 10 close to the coating pool 1. The base cloth after self-adhesive coating enters the drying chamber 10 through the feeding port 12 for drying treatment. A fixing frame 8 is fixedly installed on the outer side of the drying table 7, and a winding roller 9 is rotatably installed inside the fixing frame 8. The self-adhesive coating and the dried material are wound up by the winding roller 9.

[0032] Embodiment 3, based on embodiment 1, Figure 1 and 2 As shown, a collecting box 16 is fixedly installed on the side wall of the connecting platform 6, and a reflux pipe 17 is provided on the collecting box 16. The end of the reflux pipe 17 away from the collecting box 16 is connected to the inside of the coating pool 1. After the base cloth has completed the self-adhesive coating in the coating pool 1, it passes through two sets of scraper rollers 15 corresponding to the upper and lower parts. The scraper rollers 15 scrape off the excess polymer coating attached to the material. Some of the scraped off polymer coating will be guided into the collecting box 16 through the connecting platform 6, and finally the excess polymer coating will be returned to the coating pool 1 through the reflux pipe 17, so as to avoid the waste of excess polymer coating scraped off.

[0033] The working principle of this utility model:

[0034] The reel with the base cloth rolled up is placed on the support frame 4, and one end of the base cloth is pulled through the guide roller 5 to extend into the coating pool 1 by an external traction mechanism, and one end of the base cloth is sequentially extended through the guide roller 5 and the scraper roller 15 to the side close to the drying table 7;

[0035] By turning the hand wheel 14, the hand wheel 14 controls the base fabric extrusion mechanism 13 to rotate. The coating pool 1 stores polymer self-adhesive coating inside. The base fabric distributed in the middle of the coating pool 1 is squeezed downward by the base fabric extrusion mechanism 13, so that the base fabric contacts the polymer coating in the coating pool 1, and the polymer coating is evenly dipped on the upper and lower sides of the base fabric, thereby completing the self-adhesive coating of the base fabric. The base fabric with the coating is continuously pulled and stretched outward by two sets of scraper rollers 15. As the base fabric completes the self-adhesive coating operation, the polymer coating in the coating pool 1 becomes less and less during the production process. At this time, by turning the hand wheel 14, the hand wheel 14 is driven by the base fabric extrusion mechanism 13 to rotate eccentrically, so that the base fabric extrusion mechanism 13 is convenient for squeezing the base fabric distributed in the coating pool 1, so as to avoid the reduction of the polymer coating in the coating pool 1, which makes it difficult for the base fabric to be completely dipped in the coating. The scraper roller 15 is provided to facilitate scraping off the excess coating on the base fabric, and the base fabric with the self-adhesive coating enters the drying chamber 10 through the feed inlet 12 for drying.

[0036] After the base fabric has completed the self-adhesive coating in the coating pool 1, it passes through two corresponding sets of scraper rollers 15 above and below, and the scraper rollers 15 scrape off the excess polymer coating attached to the material. Some of the scraped off polymer coating will be guided to the collection box 16 through the connecting platform 6, and finally the excess polymer coating will be returned to the coating pool 1 through the reflux pipe 17, so as to avoid the waste of the excess polymer coating scraped off.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
