Description

Technical Field

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

[0002] The coating head mechanism of a hot stamping machine is a mechanism in the hot stamping machine for pre-coating glue on the fabric, and it can apply glue with a specific pattern on the fabric through a patterned roller.

[0003] Hot stamping machines in the prior art often use oil-based glue, which often contains flammable, explosive and toxic organic solvents such as toluene and methyl ethyl ketone, and is not environmentally friendly. Water-based glue has better environmental protection compared to oil-based glue.

[0004] In the prior art, the glue tank of the coating head mechanism of a hot stamping machine is often at the bottom of the patterned roller. In order to ensure the fluidity of water-based glue, only water-based glue with a lower viscosity can be used. Only glue with a low viscosity and large fluidity can quickly fall back to the bottom of the glue tank. However, when the water-based glue with a smaller viscosity is transferred from the patterned roller to the film, there will be phenomena such as pattern sagging and lack of fineness, resulting in defective products.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the present utility model is to provide a coating head mechanism of a hot stamping machine applicable to water-based adhesives, which can use glue with a high viscosity.

[0007] The above technical purpose of the present utility model is achieved through the following technical solutions: A coating head mechanism of a hot stamping machine applicable to water-based adhesives includes a frame. On both sides of the fabric feeding end of the frame, there are bases. Each base includes a bracket and a bottom plate. The bracket is located on the upper surface of the bottom plate. A patterned roller is rotatably connected to the bracket. On the two bottom plates, there are hydraulic cylinders. The output ends of the two hydraulic cylinders are jointly provided with a glue tank. The glue tank is located on the side of the patterned roller away from the frame. The glue tank is connected to the output end of the hydraulic cylinder through an angle adjustment component. The angle between the glue tank and the horizontal plane is 30° - 60°.

[0008] The present utility model is further provided as: The angle adjustment component includes a connecting plate in the shape of a sector and fixedly connected to the hydraulic cylinder. One side of the central angle of the connecting plate is rotatably connected to the outer side wall of the glue tank. An arc-shaped groove is opened on the connecting plate. A limiting column matching the arc-shaped groove is provided on the outer side wall of the outer side wall of the glue tank. A screw hole is opened on the limiting column.

[0009] The present utility model is further provided as: A plurality of fixing holes for fixing the hydraulic cylinders are opened on the bottom plate, and the fixing holes are arranged from the direction close to the frame to the direction away from the frame.

[0010] The present utility model is further configured such that: a scraper is provided on the glue tank, and knife rests are provided on both sides of the scraper, and one ends of the two knife rests are both fixed on the outer side wall of the glue tank.

[0011] The present utility model is further configured such that: the thickness of the scraper gradually increases from the side facing the flower roller to the side away from the flower roller.

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

[0013] By arranging the glue tank at the output end of the hydraulic cylinder, and the glue tank is located on the side of the flower roller away from the machine frame, the glue in the glue tank adheres to the flower roller from the side of the flower roller. Through the connection between the angle-adjusting assembly and the output end of the hydraulic cylinder, the angle between the glue tank and the horizontal plane can be adjusted. Since the glue tank is located on the side of the flower roller and there is an angle between the glue tank and the horizontal plane, the glue in the glue tank can flow back to the bottom of the glue tank along the inclined inner wall of the glue tank by gravity, avoiding the problem that it is difficult for the water-based glue with high viscosity to flow back, and enabling the use of water-based glue with higher viscosity.

[0017] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0018] Embodiment: A gilding machine coating head mechanism applicable to water-based adhesives, as shown in Figure 1 、 Figure 2As shown in the figure, it includes a frame 1. On both sides of the fabric inlet end of the frame 1, there are bases 2. The base 2 includes a bracket 3 and a bottom plate 4. The bracket 3 is located on the upper surface of the bottom plate 4. A pattern roller 5 is rotatably connected to the bracket 3. Hydraulic cylinders 6 are arranged on the two bottom plates 4. The hydraulic cylinders 6 are connected to a hydraulic pump. Through the adjustment of the hydraulic pump, the output ends of the hydraulic cylinders 6 can extend and contract. The output ends of the two hydraulic cylinders 6 are jointly provided with a glue tank 7. The height of the glue tank 7 can be adjusted. The glue tank 7 is located on the side of the pattern roller 5 away from the frame 1. The glue in the glue tank 7 adheres to the pattern roller 5 from the side of the pattern roller 5. Through the connection of the angle adjustment component and the output end of the hydraulic cylinder 6, the angle between the glue tank 7 and the horizontal plane can be adjusted. Further, the adjustment range of the angle between the glue tank 7 and the horizontal plane is 30° - 60°. The glue tank 7 is located on the side of the pattern roller 5 and there is an angle between the glue tank 7 and the horizontal plane. The glue in the glue tank 7 can flow back to the bottom of the glue tank 7 along the inner wall of the inclined glue tank 7 by gravity, avoiding the problem that it is difficult for the water-based glue with high viscosity to flow back, and enabling the use of water-based glue with greater viscosity.

[0019] The angle between the glue tank 7 and the horizontal plane can be adjusted, and the height of the glue tank 7 can also be adjusted, so that the flow-back speed of the glue can be controlled, and glues with more viscosities can be applicable.

[0020] The angle adjustment component includes a connecting plate 8 which is fan-shaped and fixedly connected to the hydraulic cylinder 6. One side of the central angle of the connecting plate 8 is rotatably connected to the outer side wall of the glue tank 7. An arc-shaped groove 9 is opened on the connecting plate 8. A limiting post matching the arc-shaped groove 9 is arranged on the outer side wall of the outer side wall of the glue tank 7. A screw hole is opened on the limiting post. The limiting post can move relative to the arc-shaped groove 9, and thus the angle between the glue tank 7 and the horizontal plane can be adjusted. After adjustment, a screw matching the screw hole can be used to fix the glue tank 7 and the connecting plate 8, so that the angle between the glue tank 7 and the horizontal plane is fixed.

[0021] A number of fixing holes 10 for fixing the hydraulic cylinder 6 are opened on the bottom plate 4. The fixing holes 10 are arranged from the direction close to the frame 1 to the direction away from the frame 1. Fixing the hydraulic cylinder 6 in different fixing holes 10 can make the hydraulic cylinder 6 close to or away from the pattern roller 5, which is applicable to the use state of the glue tank 7 at different angles.

[0022] A scraper 11 is arranged on the glue tank 7. Knife holders are arranged on both sides of the scraper 11. One ends of the two knife holders are both fixed on the outer side wall of the glue tank 7. The scraper 11 can scrape off the excess glue on the pattern roller 5, and the thickness of the scraper 11 gradually thickens from the side facing the pattern roller 5 to the side away from the pattern roller 5. The gradually thickening scraper 11 can gradually level the glue on the surface of the pattern roller 5, making the distribution of the glue more uniform.

All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
