Description

Technical Field

[0001] This invention relates to the field of film transfer printing, and more particularly to a roll-to-roll film transfer printing machine. Background Technology

[0002] Existing roll-to-roll UV transfer equipment uses UV adhesive to replicate fine textures through curing under ultraviolet light.

[0003] For example, Chinese patent CN222727651U discloses a drying assembly for UV transfer decorative panels, which is designed with multiple ultraviolet lamps arranged in a row. The external ultraviolet lamps can be flexibly turned on according to the size of the UV transfer product, which is more energy-efficient. However, it still has a drawback: all the ultraviolet lamps are exposed, and volatile impurities in the printing ink or dust in the production process will adhere to the surface of the lamps, resulting in a reduction in the intensity of ultraviolet light.

[0004] For example, Chinese patent CN116811428A discloses a printing device for printed materials, which uses a sponge that contacts the quartz tube wall of a UV curing lamp and can inject anhydrous ethanol into the sponge. When the reflector rotates, it can clean the quartz tube wall of the reflector. However, it still has a defect: the sponge is prone to aging and cracking when exposed to the high temperature environment of the lamp for a long time, which affects its subsequent use. Summary of the Invention

[0005] In order to overcome the shortcomings of existing UV transfer equipment in lacking an effective protective structure for ultraviolet lamps, the present invention provides a roll-to-roll film transfer machine.

[0006] Technical Solution: A roll-to-roll adhesive film transfer machine includes a transfer machine body, a housing, lamps, and partitions; the housing is mounted on the transfer machine body; multiple lamps for curing UV adhesive are installed inside the housing; multiple partitions are installed inside the housing, dividing the interior of the housing into multiple spaces, and the partitions and lamps are alternately distributed; it also includes a moving drive component and a moving plate; two pairs of moving drive components are mounted on the outer surface of the housing; each pair of moving drive components has a moving plate mounted on its driving end; the moving plate moves along the lower surface of the housing; the moving plate moves to cooperate with the partitions to seal off unused lamps.

[0007] Furthermore, it is particularly preferred that the partition is hollow inside and has through slots; an air duct is installed on the top of the cover; the air duct has multiple branches, each of which passes through the cover and communicates with one of the partitions; the air duct is used to extract the hot air between the lamps.

[0008] Furthermore, it is particularly preferred that a plurality of rotary drive components are installed on the side wall of the housing; the drive end of each rotary drive component is connected to one of the lamp tubes; and a cleaning strip for cleaning the lamp tubes is installed on each of the movable plates.

[0009] Furthermore, it is particularly preferred that the cleaning strip is made of sponge material.

[0010] Furthermore, it is particularly preferred that the cleaning strip is detachably mounted on the movable plate.

[0011] Furthermore, it is particularly preferred that the lower end face of the cover has two receiving grooves for accommodating the cleaning strip.

[0012] Furthermore, it is particularly preferred that each of the movable plates is embedded with a liquid inlet pipe, each liquid inlet pipe is in contact with a cleaning strip, and each liquid inlet pipe has a through hole on the wall surface in contact with the corresponding cleaning strip. By introducing anhydrous ethanol into the liquid inlet pipe, the anhydrous ethanol is allowed to pass through the through hole of the liquid inlet pipe and seep into the cleaning strip.

[0013] Furthermore, it is particularly preferred that a telescopic plate is slidably provided at the lower part of the partition, the lower end surface of the telescopic plate is a curved surface, and the opposing ends of the two moving plates are both curved surfaces. When the moving plate moves to the lower part of the partition, it can push the telescopic plate upward, allowing the telescopic plate to fill the internal cavity of the partition and seal the through groove.

[0014] Furthermore, it is particularly preferred that the housing, the telescopic plate, and the movable plate are all coated with a heat-insulating coating.

[0015] Furthermore, it is particularly preferred that when the two movable plates are closed at the lower opening of the cover, the lower opening of the cover can be covered.

[0016] Beneficial effects: The present invention utilizes a movable plate, in conjunction with partitions distributed between two adjacent lamp tubes, to form a closed space, thereby sealing and protecting the lamp tubes that are not in use.

[0017] This invention allows the telescopic plate to move upward inside the partition, which not only blocks the through slot of the partition, preventing the suction airflow from passing through the unused lamps and reducing the waste of suction power, thus making efficient use of suction energy, but also fills the internal cavity of the partition. The telescopic plate, coated with a heat-insulating coating, isolates the used and unused lamps, thus providing heat insulation protection for the sealed unused lamps and the cleaning strips that are also in the sealed space.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0024] Example 1: A roll-to-roll film transfer machine, such as Figures 1-4 As shown, the machine includes a main body of a transfer machine (not shown in the figure), a housing 1, lamps 2, and partitions 3 mounted on the main body of the transfer machine; multiple lamps 2 are installed inside the housing 1 at equal intervals, and four lamps 2 are shown in the figure for example. The lamps 2 are ultraviolet lamps; multiple partitions 3 are installed inside the housing 1 at equal intervals, and the partitions 3 divide the interior of the housing 1 into multiple spaces. The partitions 3 and the lamps 2 are distributed alternately, and each partition 3 is located between two adjacent lamps 2. Three partitions 3 are shown in the figure for example; the machine also includes a moving drive component 4 and a moving plate 5; two pairs of symmetrically distributed moving drive components 4 are mounted on the top of the outer surface of the housing 1. The moving drive components 4 are electrically driven push rods; each pair of moving drive components 4 has a moving plate 5 mounted on its driving end, and the two moving plates 5 are symmetrical about the central axis of the housing 1; the moving plates 5 move along the lower surface of the housing 1.

[0025] The partition 3 is hollow inside, and through slots 32 are provided on both sides of the partition 3; an air duct 6 is installed on the top of the cover 1; the air duct 6 is connected to an external pump; the air duct 6 has multiple branch pipes, each of which passes through the cover 1 and is connected to one of the partitions 3.

[0026] Multiple rotary drive components 21 are installed on the side wall of the housing 1. Four rotary drive components 21 are shown in the figure. Each rotary drive component 21 is a DD motor. The drive end of each rotary drive component 21 is connected to one of the lamp tubes 2. A cleaning strip 7 is installed on the upper surface of each moving plate 5.

[0027] The cleaning strip 7 is made of a sponge material with deformation capabilities.

[0028] The cleaning strip 7 is detachably installed on the movable plate 5, making it easy to replace the cleaning strip 7.

[0029] Two receiving grooves 11 are provided on the lower end surfaces of both sides of the cover 1.

[0030] Example 2: Based on Example 1, such as Figures 1-4 As shown, each of the movable plates 5 is embedded with a liquid inlet pipe 8, and each liquid inlet pipe 8 is in contact with a cleaning strip 7. A through hole (not shown in the figure) is provided on the wall surface of each liquid inlet pipe 8 that is in contact with the corresponding cleaning strip 7.

[0031] A telescopic plate 31 is slidably disposed at the lower part of the partition 3. The lower end surface of the telescopic plate 31 is a curved surface, and the opposing ends of the two moving plates 5 are both curved surfaces.

[0032] The surfaces of the cover 1, the telescopic plate 31, and the movable plate 5 are all coated with a heat-insulating coating.

[0033] When the two movable plates 5 are closed at the lower opening of the cover 1, they can cover the lower opening of the cover 1.

[0034] In this invention, the housing 1 is installed on the main body of the transfer machine, and the worker places the film to be transferred under the housing 1. The ultraviolet lamp 2 inside the housing 1 is used to perform UV transfer and curing on the film. This UV transfer process is common knowledge in the prior art and will not be described in detail here.

[0035] Because the size of the adhesive film varies, multiple equally spaced lamps 2 are designed (the specific number of lamps 2 depends on the actual production needs). According to the size of the transferred adhesive film, the lamps 2 within the corresponding range are turned on, while the lamps 2 outside the range of the adhesive film size are not turned on. In other words, the irradiation range of the lamps 2 is adapted to the size of the transferred adhesive film to achieve efficient use of energy.

[0036] Furthermore, since the lamp tubes 2 may be affected by volatile impurities in the printing ink or dust from the production process, it is necessary to protect the lamp tubes 2 that are not in use. At this time, the moving drive component 4 is controlled to move the moving plate 5 along the lower surface of the cover 1. Taking the leftmost lamp tube 2 that is not in use as an example, the left moving plate 5 is controlled to move to the right end to contact the leftmost partition 3, so that the left moving plate 5, the leftmost partition 3 and the cover 1 together form a closed protective space, covering and sealing the leftmost lamp tube 2 to prevent the adhesion of external dust and impurities. By analogy, the left moving plate 5 can contact the partition 3 one by one from left to right, and the lamp tubes 2 can be sealed and protected one by one. The right moving plate 5 moves from right to left in the same way to achieve sealing and protection of the lamp tubes 2 that are not in use on both sides.

[0037] Furthermore, the partition 3 is designed as a hollow structure, and the air duct 6 is pre-connected to the external pump. The heat from the lamp tube 2 is drawn away from the through groove 32 and then drawn outward along the inside of the partition 3 and the air duct 6. This allows the partition 3, which is distributed between two adjacent lamp tubes 2, to be used as a heat dissipation element to quickly remove the heat from the gaps between multiple lamp tubes 2 that are evenly distributed, thereby improving the heat dissipation efficiency of the array lamp tubes 2.

[0038] Furthermore, in order to clean the lamp tube 2, a sponge cleaning strip 7 is installed on the moving plate 5. After the lamp tube 2 is used up, the moving plate 5 is controlled to move so that the cleaning strip 7 is directly below the lamp tube 2 and in contact with the lamp tube 2. The liquid inlet pipe 8 is pre-connected to the external anhydrous ethanol delivery pump. Anhydrous ethanol is introduced into the liquid inlet pipe 8, allowing the anhydrous ethanol to seep into the cleaning strip 7 through the through hole of the liquid inlet pipe 8. At the same time, the rotating drive component 21 is started to drive the lamp tube 2 to rotate one or two revolutions. In this way, the surface of the lamp tube 2 is wiped clean by the cleaning strip 7 with anhydrous ethanol. The cleaning strip 7 is moved to multiple lamp tubes 2 in sequence to wipe and clean them, thus completing the cleaning operation.

[0039] In its initial state, the cleaning strip 7 is housed within the receiving groove 11 of the housing 1. The housing 1 with its heat-insulating coating and the movable plate 5 provide heat insulation protection for the cleaning strip 7, reducing the impact of heat emitted by the lamp tube 2 during operation on the cleaning strip 7. However, to close the lamp tube 2 when it is not in use, the position of the movable plate 5 needs to be adjusted. Moving the movable plate 5 will cause the cleaning strip 7 to move out of the receiving groove 11 (since the cleaning strip 7 is made of deformable sponge material, it can move in and out). Therefore, a telescopic plate 31 is added inside the partition 3. When the end of the movable plate 5 moves to the corresponding position of the partition 3, it will contact the lower end of the telescopic plate 31 inside the partition 3. The curved end of the movable plate 5 pushes the telescopic plate 31 upward (similar to the pushing principle of the wedge structure), causing the telescopic plate 31 to move upward inside the partition 3. This allows the telescopic plate 31 to not only block the through slot 32 of the partition 3, preventing the suction airflow from passing through the unused lamp tube 2 and reducing the waste of suction power, thus making efficient use of suction energy, but also fill the internal cavity of the partition 3. The telescopic plate 31, coated with a heat-insulating coating, isolates the used and unused lamp tube 2 between them, thus providing heat insulation protection for the sealed unused lamp tube 2 and the cleaning strip 7, which is also in the sealed space.

[0040] Furthermore, after the lamp tube 2 has finished working, when the two movable plates 5 are closed at the lower opening of the cover 1, the lower opening of the cover 1 is covered, thereby achieving the sealing and dust prevention of all lamp tubes 2.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
