Description

Technical Field

[0001] The utility model relates to the field of hot stamping machines, and more specifically, to a coating head mechanism of a hot stamping machine. Background Art

[0002] The coating head mechanism of the hot stamping machine is the mechanism used for gluing the hot stamping machine, which is used to apply glue on the surface of the hot stamping film.

[0003] The coating head mechanism of the prior art hot stamping machine often includes a glue groove and a pattern roller. The glue groove is a long groove with a rectangular cross-section. The pattern roller adheres glue from the glue groove, and the excess glue will be scraped off by the scraper and flow back into the glue groove. Due to the high viscosity of the glue, the speed of the glue flowing in the horizontal direction is slow. After the glue falls into the glue groove, the glue liquid level is not easy to level out, which will cause the glue liquid level below the scraper to be higher and the glue liquid level below the pattern roller to be lower, and the dipping effect of the pattern roller will be poor.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a coating head mechanism for a hot stamping machine, which makes it easier for glue to fall off.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: the hot stamping machine coating head mechanism includes a frame, bases are arranged on both sides of the cloth feeding end of the frame, flower roller frames are arranged on the two bases, and flower rollers are connected to the two flower roller frames for common rotation, a glue groove is arranged on the base, the inner wall of the glue groove is arc-shaped, the projection of the center axis of the flower roller on the glue groove is located on the line connecting the lowest points of the glue groove, the end of the glue groove away from the frame is higher than the end of the glue groove facing the frame, a baffle is arranged on the end of the glue groove away from the frame, and the bottom of the glue groove is slidably connected to the base through a sliding component.

[0007] The utility model is further configured as follows: the sliding assembly includes a sliding block fixedly connected to the bottom of the glue groove, sliding grooves matching the sliding block are provided on the sides of the two bases, the sliding grooves extend to the top surface of the base, and the sliding block and the sliding groove are detachably connected with a fixing piece for fixing the sliding block.

[0008] The utility model is further configured as follows: a first opening is opened on the side of the sliding block, a plurality of second openings are opened on the groove wall of the sliding groove, and the first opening and the second openings together form a locking opening matched with the fixing member.

[0009] The utility model is further configured as follows: a holding ring is arranged on the fixing member.

[0010] The utility model is further configured as follows: an L-shaped bracket is arranged on the base, a scraper is arranged on the top of the bracket, the scraper includes a knife body fixedly connected to the bracket and a scraping part facing the flower roller, the scraper is arranged obliquely and the end of the scraper facing the flower roller is higher than the end of the scraper away from the flower roller.

[0011] The utility model is further configured as follows: a plurality of drainage grooves are provided on the scraping part, and the drainage grooves are perpendicular to the pattern roller.

[0012] In summary, the utility model has the following beneficial effects:

[0013] The utility model is provided with a glue groove on the base, and the inner wall of the glue groove is in an arc shape, and the projection of the center axis of the flower roller on the glue groove is located on the line connecting the lowest points of the glue groove. Since the inner wall of the glue groove is in an arc shape, the projection of the center line of the glue liquid level in the glue groove on the glue groove coincides with the line connecting the lowest points of the glue groove. When the glue slides along the inner wall of the glue groove, the glue falls closer to the center line of the glue liquid level, thereby reducing the horizontal movement distance of the glue, so that the glue is easier to fall back to the lowest point of the glue groove and contact the flower roller.

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment: Hot stamping machine coating head mechanism, such as Figure 1-Figure 4As shown, it includes a frame 1, bases 2 are arranged on both sides of the cloth feeding end of the frame 1, and flower roller frames 3 are arranged on the two bases 2. Flower rollers 4 are connected to the two flower roller frames 3 for common rotation, and a glue groove 5 is arranged on the base 2. The inner wall of the glue groove 5 is in an arc shape, and the projection of the central axis of the flower roller 4 on the glue groove 5 is located on the line connecting the lowest points of the glue groove 5. When in use, glue is injected into the glue groove 5. Since the inner wall of the glue groove 5 is in an arc shape, the projection of the center line of the glue liquid level in the glue groove 5 on the glue groove 5 coincides with the line connecting the lowest points of the glue groove 5. When the glue slides along the inner wall of the glue groove 5, the glue falls closer to the center line of the glue liquid level, which reduces the horizontal movement distance of the glue, making it easier for the glue to fall back to the lowest point of the glue groove 5 and contact the flower roller 4.

[0021] like Figure 3 , Figure 4 As shown, the end of the glue groove 5 away from the frame 1 is higher than the end of the glue groove 5 facing the frame 1 , and a baffle 6 is provided at the end of the glue groove 5 away from the frame 1 to block the dripping glue and reduce the glue from dripping out of the glue groove 5 .

[0022] like Figure 1 , Figure 2 As shown, the bottom of the glue groove 5 is slidably connected to the base 2 through a sliding assembly, and the sliding assembly includes a slider 7 fixedly connected to the bottom of the glue groove 5. The sides of the two bases 2 are provided with sliding grooves 8 matching the slider 7, and the sliding groove 8 extends to the top surface of the base 2. The slider 7 and the sliding groove 8 are detachably connected with a fixing part 9 for fixing the slider 7. By sliding the slider 7 in the sliding groove 8, the glue groove 5 can be moved up and down. The downward movement of the glue groove 5 can increase the gap between the glue groove 5 and the flower roller 4, which can make it more convenient to add glue. The upward movement of the glue groove 5 can make the flower roller 4 better contact with the glue.

[0023] like Figure 2 As shown, a first opening 10 is provided on the side of the slider 7, and a plurality of second openings 11 are provided on the groove wall of the sliding groove 8. The first opening 10 and the second opening 11 together form a locking opening 12 matching the fixing member 9. The fixing member 9 is inserted into the locking opening 12, and the slider 7 is locked by the fixing member 9. The slider 7 cannot slide in the sliding groove 8, so that the upper and lower positions of the rubber groove 5 are fixed. A gripping ring is provided on the fixing member 9, and the user can grasp the gripping ring and apply force, so that the fixing member 9 can be inserted and pulled out of the locking opening 12.

[0024] like Figure 3 , Figure 4As shown, an L-shaped bracket is provided on the base 2, and a scraper is provided on the top of the bracket. The scraper includes a blade body 13 fixedly connected to the bracket and a scraping portion 14 facing the flower roller 4. The scraper is inclined and the end of the scraper facing the flower roller 4 is higher than the end of the scraper away from the flower roller 4. When excess glue on the flower roller 4 is scraped off by the scraping portion 14 of the scraper, the inclination of the scraper can guide the glue to flow toward the baffle 6 to prevent the fallen glue from dripping on the flower roller 4 again.

[0025] like Figure 3 , Figure 4 As shown, a plurality of drainage grooves 15 are provided on the scraper 14, and the drainage grooves 15 are perpendicular to the pattern roller 4. The drainage grooves 15 can better guide the flow of glue and reduce the lateral flow of glue.
