Description

Technical Field

[0001] The utility model relates to the technical field of pattern transfer, in particular to a transfer molding machine. Background Art

[0002] During the transfer process of the molding machine, the transfer plate roller rotates and presses the film material in coordination with the transfer rubber roller to transfer the pattern on the transfer plate roller to the UV varnish on one side of the film material. Most areas of the outer circumference of the transfer plate roller are engraved with the pattern to be transferred, so that its surface is not smooth and uniform, and the corresponding outer diameters of each area are slightly different, resulting in the instantaneous linear speed of the transfer rubber roller and the instantaneous transmission speed of the film material not being completely consistent, causing the transfer plate roller to slightly pull the film material. Due to the continuous rotation of the transfer plate roller and the transfer rubber roller and the continuous forward transmission of the film material, the film material will eventually be deformed to a certain extent during the long-term accumulation process, which also affects the pattern transfer quality.

[0020] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0021] Reference Figure 1 and Figure 2 The utility model discloses an intermittent transfer molding machine, comprising a workbench 1, on which a discharge roller 3, a coating anilox roller 4, a coating tank 5, a drying tunnel 6, a transfer plate roller 7, a transfer rubber roller 8, a UV curing lamp 9 and a winding roller 10 are sequentially arranged from back to front along the transmission direction of a film material 2.

[0022] The unwinding roller 3 is used to unwind the film material 2 to be transferred, and the winding roller 10 is used to wind up the transferred film material 2. The unwinding roller 3 and the winding roller 10 can rotate automatically to realize the forward transmission of the film material 2.

[0023] Reference Figure 1 UV varnish can be placed in the coating tank 5, and the coating anilox roller 4 is configured to adhere to the UV varnish in the coating tank 5 and transfer it to one side of the film material 2, so that the UV varnish is coated on one side of the film material 2. The drying tunnel 6 has multiple groups of heating tubes 61 arranged in sequence along the transmission direction of the film material 2. The heating tubes 61 are used to radiate and heat the UV varnish on one side of the film material 2. Since the surface flatness of the newly coated UV varnish is slightly poor, the heating tubes 61 radiate and heat the UV varnish while ensuring temperature balance, which can keep the UV varnish on the film material 2 flat.

[0024] Further references Figure 2 The outer peripheral surface of the transfer plate roller 7 is engraved with a pattern. The transfer plate roller 7 can approach the transfer rubber roller 8 and press the film material 2 onto the transfer rubber roller 8, and rotate synchronously for one circle to transfer the pattern to the UV varnish on one side of the film material 2. Then the transfer plate roller 7 stops rotating and the film material 2 stops transmitting, and the transfer plate roller 7 first moves away from the transfer rubber roller 8 to loosen the film material 2, and then approaches the transfer rubber roller 8 and presses the film material 2 onto the transfer rubber roller 8.

[0025] The irradiation direction of the UV curing lamp 9 is directly facing the film material 2 , so that the UV varnish on one side of the film material 2 can be cured.

[0026] Reference Figure 1 and Figure 2 The layout of the molding machine is reasonable. The film material 2 released by the unwinding roller 3 can be coated with the UV varnish in the coating tank 5 through the coating anilox roller 4. The film material 2 can be radiantly heated after passing through the drying tunnel 6, so that the UV varnish on the film material 2 remains flat. The transfer plate roller 7 transfers the pattern to the UV varnish on one side of the film material 2. Since the transfer plate roller 7 stops rotating after each rotation and the film material 2 stops transmitting, the transfer plate roller 7 first moves away from and then approaches the transfer rubber roller 8, that is, the film material 2 is first loosened and then pressed, eliminating the stress and pulling of the transfer plate roller 7 and the transfer rubber roller 8 on the film material 2, thereby reducing the deformation of the film material 2 and improving the pattern transfer quality.

[0027] Then the transfer plate roller 7 continues to rotate and the film material 2 continues to be transported, and the UV varnish is cured by the UV curing lamp 9 before the film material 2 is rolled up.

[0028] Reference Figure 2 In some embodiments of the utility model, a linear drive unit 11 is provided on the workbench 1, and the linear drive unit 11 is connected to a transmission block 12, and the transfer plate roller 7 is installed on the transmission block 12. The linear drive unit 11 can drive the transfer plate roller 7 to approach or move away from the transfer rubber roller 8.

[0029] In some embodiments, the linear driving unit 11 can drive the transmission block 12 to move vertically, that is, when the transmission block 12 moves vertically, the transfer plate roller 7 moves closer to or away from the transfer rubber roller 8 .

[0030] Reference Figure 2 In some embodiments, the transmission block 12 is provided with a slide groove 121 extending in the vertical direction, the transfer plate roller 7 is slidably connected to the slide groove 121, and the slide groove 121 is also slidably connected to the pressure roller 13, the pressure roller 13 and the transfer plate roller 7 are distributed up and down and can slide freely relative to the slide groove 121, the pressure roller 13 always presses on the transfer plate roller 7 by its own weight, when the transfer plate roller 7 is close to the transfer rubber roller 8, the pressure roller 13, the transfer plate roller 7 and the transfer rubber roller 8 are arranged in sequence from top to bottom in the vertical direction, when the transfer plate roller 7 transfers the pattern to the UV varnish on one side of the film material 2, the transfer plate roller 7 is pressed down by the gravity of the transfer rubber roller 8, so as to realize the load transfer of the transfer plate roller, which is beneficial to transfer the pattern to the UV varnish, and the transfer plate roller 7 will not be subjected to the overload force, so as to prevent the film material 2 from being crushed.

[0031] In addition, the linear drive unit 11 can be specifically a servo cylinder. When the linear drive unit 11 drives the transmission block 12 to descend, the transfer plate roller 7 will be pressed against the film material 2 and the transfer rubber roller 8. Even if the transmission block 12 continues to descend for a distance, it will not affect the position of the transfer plate roller 7 relative to the transfer rubber roller 8. Similarly, when the linear drive unit 11 drives the transmission block 12 to rise a certain distance, the transfer plate roller 7 will be gradually lifted and away from the transfer rubber roller 8. In this way, the driving accuracy requirements of the linear drive unit 11 are reduced.

[0032] Reference Figure 1 In some embodiments of the utility model, the coating anilox roller 4 partially extends into the UV varnish in the coating tank 5, and the workbench 1 is installed with a coating rubber roller 14 at a position close to the coating anilox roller 4. A coating channel for the film material 2 to pass through is formed between the coating anilox roller 4 and the coating rubber roller 14. When the film material 2 passes through the coating channel, it is coated with UV varnish by the coating anilox roller 4.

[0033] In addition, in some embodiments, a scraper is installed on the outside of the coating anilox roller 4 on the workbench 1, and the scraper abuts against the outer surface of the coating anilox roller 4. The scraper can scrape off excess UV varnish on the coating anilox roller 4 to ensure coating stability and uniformity and improve transfer accuracy.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
