Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to a heated coating doctor blade roller. Background Technology

[0002] Heated coating doctor rollers are key equipment used in precision coating processes to control and improve coating quality. They combine the quantitative function of mechanical doctor blades with the temperature control function of active heating, and are widely used in new energy, electronics, optical films, adhesive tapes, and other fields. A heated coating doctor roller consists of a roller body and a doctor blade disposed on the outer surface of the roller body. The doctor blade is arranged along the axial direction of the roller body. The heated coating doctor roller cooperates with a back roller (coating roller), and the amount of coating transferred onto the substrate is precisely controlled through the gap between the two.

[0003] In existing technologies, the doctor blades on heated coating doctor blade rollers are formed by machining the roller body. Since the doctor blades scrape the coating on the back roller to ensure uniform coating on the substrate during the rotation of the roller body, the machining accuracy of the doctor blades is required to be very high, which leads to high processing costs for coating doctor blade rollers. In addition, during subsequent operation of the coating doctor blade roller, local wear of the doctor blades can cause the scraping amount in some parts to be greater than in other parts, resulting in uneven coating on the substrate and leading to the high cost of replacing the entire roller body. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heated coating doctor blade roller to solve the problem of high overall processing cost and high cost caused by the need to replace the entire roller body after the doctor blade wears in some areas.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a heated coating doctor roller, including an inner roller body, multiple upper doctor roller bodies, multiple lower doctor roller bodies, multiple upper connecting roller bodies, and multiple lower connecting roller bodies. The multiple upper connecting roller bodies are continuously arranged axially on the upper surface of the inner roller body, and the multiple lower connecting roller bodies are continuously arranged axially on the lower surface of the inner roller body. The multiple upper connecting roller bodies and the multiple lower connecting roller bodies are arranged vertically in correspondence. The upper connecting roller bodies and the lower connecting roller bodies are respectively fixedly installed on the upper and lower surfaces of the inner roller body. The multiple upper doctor roller bodies are respectively concentrically fixedly installed on the outer surfaces of the multiple upper connecting roller bodies, and the multiple lower doctor roller bodies are respectively concentrically installed on the outer surfaces of the multiple lower connecting roller bodies. A doctor blade is provided axially on the outer surface of the upper doctor roller body. The multiple upper doctor roller bodies, lower doctor roller bodies, upper connecting roller bodies, and lower connecting roller bodies are fixedly connected by connecting bolts.

[0007] Furthermore, the outer surfaces of the upper connecting roller and the lower connecting roller are respectively provided with a plurality of upwardly extending upper connecting protrusions and lower connecting protrusions. The upper connecting protrusions are arranged along the axial direction of the upper connecting roller, and the lower connecting protrusions are arranged along the axial direction of the lower connecting roller. The plurality of upper connecting protrusions are evenly spaced along the circumferential direction of the upper connecting roller, and the plurality of lower connecting protrusions are evenly spaced along the circumferential direction of the lower connecting roller. The inner walls of the upper scraper roller and the lower scraper roller are respectively provided with upper connecting grooves and lower connecting grooves that engage with the plurality of upper connecting protrusions and lower connecting protrusions.

[0008] Furthermore, the width of the upper connecting protrusion and the lower connecting protrusion gradually increases outward.

[0009] Furthermore, the inner roller body has a hollow roller body shape structure.

[0010] Furthermore, the outer edges of the upper connecting roller and the lower connecting roller are respectively provided with connecting holes, and the outer edges of the upper scraper roller and the lower scraper roller are respectively provided with through holes and threaded holes. The through holes and threaded holes are respectively connected to the connecting holes, wherein the through holes on the lower scraper roller and the threaded holes on the lower scraper roller are on the same side.

[0011] Furthermore, the outer surface of the inner roller body is provided with a groove arranged in the circumferential direction, and the inner walls of the upper connecting roller body and the lower connecting roller body are respectively provided with a locking block that matches the groove.

[0012] Beneficial effects:

[0013] This embodiment employs the aforementioned heated coating doctor blade roller, with the doctor blade roller body using a modular design. Multiple upper and lower doctor blade roller bodies are installed on the outer surface of the inner roller body in a separate modular form. In this way, when the doctor blade at a certain position is worn and damaged, only the upper doctor blade roller body at that position needs to be replaced to complete the repair of the doctor blade roller, thus reducing the maintenance and replacement cost of the doctor blade roller.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] See appendix Figures 1 to 5As shown, this embodiment provides a heated coating doctor blade roller 100, including an inner roller body 10, a plurality of upper doctor blade roller bodies, a plurality of lower doctor blade roller bodies 40, a plurality of upper connecting roller bodies 30 and a plurality of lower connecting roller bodies 20, wherein the number of upper doctor blade roller bodies, lower doctor blade roller bodies 40, upper connecting roller bodies 30 and lower connecting roller bodies 20 are the same.

[0030] Reference Figure 1 and Figure 2 As shown, in this embodiment, multiple upper connecting rollers 30 are continuously arranged on the upper circumferential surface of the inner roller 10, and correspondingly, multiple lower connecting rollers 20 are continuously arranged on the lower circumferential surface of the inner roller 10. The upper connecting rollers 30 and the lower connecting rollers 20 are arranged opposite each other.

[0031] Reference Figure 3 and Figure 4 As shown, in some embodiments, to facilitate the fixed installation of the upper connecting roller 30 and the lower connecting roller 20 on the inner roller 10, the outer surface of the inner roller 10 is provided with grooves 11 arranged in the circumferential direction. There are multiple grooves 11, spaced apart along the axial direction of the inner roller 10, i.e., one groove 11 corresponds to one upper connecting roller 30 and one lower connecting roller 20. Correspondingly, the inner walls of the upper connecting roller 30 and the lower connecting roller 20 are respectively provided with locking blocks 70 that match the grooves 11. The grooves 11 and locking blocks 70 can restrict the axial movement of the upper connecting roller 30 (or the lower connecting roller 20) on the inner roller 10.

[0032] Reference Figures 1 to 3 As shown, in some embodiments, in order to reduce the weight of the entire scraper roller, the inner roller body 10 has a hollow roller body shape structure.

[0033] Reference Figure 1 and Figure 2 As shown, multiple upper scraper rollers 50 are concentrically fixed on the outer surfaces of multiple upper connecting rollers 30, and multiple lower scraper rollers are concentrically fixed on the outer surfaces of multiple lower connecting rollers 20. Scrapers are axially arranged on the outer surface of each upper scraper roller 50. The multiple upper scraper rollers, lower scraper rollers 40, upper connecting rollers 30, and lower connecting rollers 20 are fixedly connected by connecting bolts 60. The upper scraper rollers 50, lower scraper rollers, upper connecting rollers 30, and lower connecting rollers 20 are modularly mounted on the outer surface of the inner roller 10. This allows for easy repair of the scraper rollers by simply replacing the upper scraper roller at that location when a scraper at a certain position becomes worn or damaged, thus reducing the maintenance and replacement costs of the scraper rollers.

[0034] Reference Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, the outer surfaces of the upper connecting roller 30 and the lower connecting roller 20 are respectively provided with a plurality of upwardly extending upper connecting protrusions 31 and lower connecting protrusions 21. The upper connecting protrusions 31 are arranged along the axial direction of the upper connecting roller 30, and the lower connecting protrusions 21 are arranged along the axial direction of the lower connecting roller 20. The plurality of upper connecting protrusions 31 are evenly spaced along the circumferential direction of the upper connecting roller 30, and the plurality of lower connecting protrusions 21 are evenly spaced along the circumferential direction of the lower connecting roller 20. The inner walls of the upper scraper roller 40 and the lower scraper roller 40 are respectively provided with the plurality of upper connecting protrusions 31 and 21. The upper connecting groove 51 and the lower connecting groove 41 that engage with the lower connecting protrusion 21, the cooperation between the upper connecting roller 30 and the upper scraper roller 31 and the upper connecting groove 51, and the cooperation between the lower connecting roller 20 and the lower scraper roller 40, can all enable the upper connecting roller 30 and the lower connecting roller 20 to be positioned and installed on the upper scraper roller 30 and the lower scraper roller 40 respectively, thereby improving the accuracy of the installation position of the upper scraper roller 30 and the lower scraper roller 40 on the upper connecting roller 30 and the lower connecting roller 20.

[0035] Reference Figure 2 and Figure 4 As shown, in some embodiments, the upper connecting protrusion 31 and the lower connecting protrusion 21 have an outer width that gradually increases outwards. This outer structure improves the bonding force (bonding strength) with the upper scraper roller (or lower scraper roller 40) and more effectively prevents the upper scraper roller (or lower scraper roller 40) from separating from the upper connecting protrusion 31 (or lower connecting protrusion 21). For example, the upper connecting protrusion 31 and the lower connecting protrusion 21 can be formed with a generally inverted trapezoidal cross-sectional shape.

[0036] Reference Figure 5 As shown, in some embodiments, connecting holes are respectively provided on the outer edges of the upper connecting roller 30 and the lower connecting roller 20, and through holes and threaded holes are respectively provided on the outer edges of the upper scraper roller 40 and the lower scraper roller 40. The through holes and threaded holes are connected to the connecting holes. The through holes and threaded holes on the lower scraper roller 40 are on the same side, that is, the through holes on the upper scraper roller 40 and the through holes on the lower scraper roller 40 are staggered. Similarly, the threaded holes on the upper scraper roller 40 and the threaded holes on the lower scraper roller 40 are staggered. For example, if the left side of the upper scraper roller 40 is a through hole, then the left side of the lower scraper roller 40 is a threaded hole. By staggering the through holes and threaded holes on the upper scraper roller 40 and the lower scraper roller 40, the heads of the connecting bolts 60 installed on them are also arranged symmetrically, thereby making it easy to adjust the overall weight balance of the rollers.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
