Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer printing processing, in particular to a heat transfer printing device. Background Art

[0002] For a traditional heat transfer printing device on the market at present, it first prints a desired pattern onto a transfer medium through ink, then evenly sprinkles hot melt powder on the transfer medium through a supporting powder shaking mechanism, and then melts and cures the hot melt powder adhered by the ink on the transfer medium through a heating mechanism. Then, the transfer medium is stacked on materials such as clothes, and finally the materials are transported to a heat transfer printing mechanism at other workstations, and the required pattern is heat transfer printed onto the materials through the heat transfer printing mechanism.

[0003] However, traditional heat transfer printing printers need to arrange multiple mechanisms such as a powder shaking mechanism, a heating mechanism, and a heat transfer printing mechanism relatively separately and far away from each other, so there are deficiencies in unreasonable structural layout and large space occupation caused thereby.

[0004] Therefore, there is an urgent need to provide a heat transfer printing device with a reasonable structural layout and small space occupation. Summary of the Utility Model

[0005] In view of the unreasonable structural layout and large space occupation of the above-mentioned existing technology, to achieve an object of the utility model, a heat transfer printing device is provided, including: a conveying mechanism for conveying a transfer medium; a printing mechanism, a powder shaking mechanism, and a powder supply mechanism arranged in sequence along the conveying direction of the transfer medium conveyed by the conveying mechanism. The first surface of the transfer medium receives inkjet from the printing mechanism to obtain a heat transfer printing pattern. The transfer medium passes through both sides of the powder supply mechanism in a relatively reverse movement manner. The powder supply mechanism supplies hot melt powder to the first surface so that the heat transfer printing pattern adheres to the hot melt powder. The powder shaking mechanism supports and shakes the second surface of the transfer medium opposite to the first surface, so that the excess hot melt powder in the area other than the heat transfer printing pattern on the first surface is shaken off.

[0006] Further, the powder shaking mechanism includes a pair of shaking rollers. The powder supply mechanism is located below the gap between the pair of shaking rollers. The transfer medium is bent between the pair of shaking rollers to form a U-shaped portion. The powder supply mechanism is close to the inner bottom surface of the U-shaped portion. The pair of shaking rollers respectively support both ends of the U-shaped portion and shake in the vertical direction.

[0007] Further, the central axes of the pair of shaking rollers are aligned with each other horizontally, and the pair of shaking rollers shake synchronously upward or downward in the vertical direction.

[0008] Further, the pair of shaking rollers reciprocally move synchronously upward or downward, so as to shake off the excess hot melt powder located in the U-shaped portion. When the pair of shaking rollers move upward to the highest position, the powder supply mechanism is spaced above the U-shaped portion.

[0009] Further, the powder feeding mechanism includes a rotating assembly, a hollow cylinder rotatably connected thereto, and a powder feeding mechanism located inside the hollow cylinder. A plurality of powder dropping holes are formed in the outer periphery of the hollow cylinder. The powder feeding mechanism is used to supply hot melt powder into the hollow cylinder. The rotating assembly includes a rotating motor and a rotating shaft. The rotating shaft is fixedly connected to the hollow cylinder in the central axis direction of the hollow cylinder. The rotating motor drives the rotating shaft to drive the hollow cylinder to rotate, so that the hot melt powder continuously falls through the powder dropping holes onto the first surface of the transfer medium.

[0010] Further, the heat transfer printing device further includes a heat preservation mechanism and a heat transfer printing processing mechanism that are located downstream of the powder shaking mechanism and the powder feeding mechanism relative to the conveying direction. The heat preservation mechanism and the heat transfer printing processing mechanism have a spaced space in the vertical direction to heat the second surface and the first surface of the transfer medium passing through the spaced space respectively, so that the heat transfer printing pattern and the hot melt powder are both heated, thereby melting and drying the hot melt powder on the heat transfer printing pattern.

[0011] Further, the heat transfer printing device further includes a finished product storage mechanism for receiving and storing the finished transfer medium. The finished transfer medium has a heat transfer printing pattern. The conveying mechanism includes a first guiding roller, a second guiding roller, and a third guiding roller. The first guiding roller is used to guide the transfer medium towards the printing mechanism. The second guiding roller is used to guide the transfer medium adhered with hot melt powder towards the spaced space. The third guiding roller is used to guide the transfer medium through the spaced space towards the finished product storage mechanism.

[0012] Further, the heat transfer printing device further includes a cutting knife mechanism. In the conveying direction, the cutting knife mechanism is located between the spaced space and the finished product storage mechanism. The cutting knife mechanism is used to cut a predetermined area of the transfer medium including the heat transfer printing pattern to obtain the finished transfer medium.

[0013] Further, the heat transfer printing processing mechanism includes a heat preservation box body having an opening and an inner cavity, a heating plate arranged in the inner cavity, and a support frame that moves into or out of the inner cavity relative to the opening. The support frame that moves outwards receives and supports the material with the finished transfer medium stacked thereon. The support frame that moves inwards makes the heating plate abut against the finished transfer medium, so as to transfer the heat transfer printing pattern with the hot melt powder that has been melted and dried onto the material.

[0014] Further, the printing mechanism, the heat preservation mechanism, and the heat transfer printing processing mechanism are sequentially spaced apart relative to each other in the vertical direction. In the vertical direction, both the powder shaking mechanism and the powder feeding mechanism are located between the printing mechanism and the heat preservation mechanism. In the horizontal direction, relative to a vertical space that simultaneously accommodates the printing mechanism, the heat preservation mechanism, and the heat transfer printing processing mechanism, the powder shaking mechanism and the powder feeding mechanism are located on one outer side of the vertical space, and the finished product storage mechanism is located on the other opposite outer side of the vertical space.

[0015] The beneficial effects of the present utility model are as follows:

[0016] The heat transfer printing device of the present utility model has the advantages of reasonable structural layout and small space occupation by adopting a structure in which the transfer medium moves reversely relative to the powder supply mechanism from both sides thereof and a powder shaking mechanism is arranged upstream of the transfer medium relative to the powder supply mechanism.

If there is no conflict, the embodiments of the present utility model and the various features in the embodiments may be combined with each other, and all are within the protection scope of the present utility model.

[0023] Please refer to Figure 1, as an object of the present utility model, a heat transfer printing device is provided, which includes a conveying mechanism and a printing mechanism 1, a powder shaking mechanism, and a powder supply mechanism 2 arranged in sequence along the conveying direction of the transfer medium by the conveying mechanism. The transfer medium can specifically be a PET transparent film as a heat transfer film. The printing mechanism 1 can be a printing carriage and can perform printing operations in a reciprocating or Single-Pass manner. Preferably, a printing platform for supporting the transfer medium to pass through is arranged below the printing mechanism 1. The first side of the transfer medium, which can be understood as the front side, receives the inkjet of the printing mechanism 1 to obtain a heat transfer printing pattern. That is to say, a heat transfer printing pattern formed by ink droplets is obtained through inkjet printing. The transfer medium passes through both sides of the powder supply mechanism 2 in a relatively reverse movement, that is, a folding movement. The powder supply mechanism 2 supplies hot melt powder to the first side so that the heat transfer printing pattern adheres to the hot melt powder. The powder shaking mechanism supports and shakes the second side of the transfer medium, which is opposite to the first side and can also be understood as the back side, so that the excess hot melt powder in the area other than the heat transfer printing pattern on the first side is shaken off. Therefore, by making the transfer medium pass through both sides of the powder supply mechanism 2 in a reverse movement relative to it, and arranging a powder shaking mechanism upstream of the transfer medium relative to the powder supply mechanism 2, the heat transfer printing device has the advantages of reasonable structural layout and small space occupation.

[0024] Specifically, the powder shaking mechanism includes a pair of shaking rollers 3. The powder supply mechanism 2 is located below the gap between the pair of shaking rollers 3. The transfer medium bends between the pair of shaking rollers 3 to form a U-shaped portion. The powder supply mechanism 2 is close to the inner bottom surface of the U-shaped portion. The pair of shaking rollers 3 respectively support both ends of the U-shaped portion and shake in the vertical direction, thereby shaking the second side. In this way, when the heat transfer printing pattern passes through the powder supply mechanism 2 in the shape of a U-shaped portion, it can fully and evenly receive the hot melt powder discharged by the powder supply mechanism 2, and the excess hot melt powder discharged in the area of the transfer medium other than the heat transfer printing pattern, under the action of its own gravity and the shaking of the powder shaking mechanism, the excess hot melt powder can be reliably shaken off and slide towards the inner surface of the U-shaped portion.

[0025] Preferably, the central axes of the pair of shaking rollers 3 are aligned with each other horizontally, and the pair of shaking rollers 3 shake synchronously upward or downward in the vertical direction. In this way, by using the two shaking rollers 3 to shake vertically up and down, on the basis of the self-gravity of the excess hot melt powder, two opposite forces, the same or opposite, are repeatedly applied relative to the direction of gravity. As a result, the inertial force of the excess hot melt powder is much greater than the frictional force of the transfer medium it receives, making it easy for the excess hot melt powder to break away from the attachment of the transfer medium and be shaken off. Thus, the excess hot melt powder drops from the surface of the transfer medium that has already passed through the powder supply mechanism 2 to the inner surface of the U-shaped portion for the next heat transfer printing pattern that comes with the movement of the transfer mechanism to adhere to. Therefore, it can particularly adapt to various particle values of hot melt powder with smaller particle values and significantly improve the powder shaking efficiency.

[0026] Please refer to Figure 2, specifically, a pair of jitter rollers 3 reciprocate synchronously upward or downward to shake off the excess hot melt powder located in the U-shaped part. When the pair of jitter rollers 3 move upward to the highest position, the powder supply mechanism 2 is intermittently located above the U-shaped part. Therefore, the stroke h of the synchronous up-and-down movement of the pair of jitter rollers 3 can generate a large jitter amplitude, thus generating a large shaking force on the excess hot melt powder, so it has a very good powder shaking effect. Moreover, even when the pair of jitter rollers 3 move upward to the highest position, they will not interfere with the U-shaped part, thus ensuring the reliable operation of the heat transfer printing device.

[0027] Specifically, the powder supply mechanism 2 includes a rotating assembly, a hollow cylinder connected by rotation, and a powder feeding mechanism located inside the hollow cylinder. A plurality of powder dropping holes are formed on the outer circumference of the hollow cylinder. The powder feeding mechanism is used to supply hot melt powder into the hollow cylinder. The rotating assembly includes a rotating motor and a rotating shaft. It can be known that the rotating motor and the rotating shaft can be fixedly connected separately or integrally. The rotating shaft is fixedly connected to the hollow cylinder in the central axis direction of the hollow cylinder. The rotating motor drives the rotating shaft to drive the hollow cylinder to rotate so as to continuously make the hot melt powder fall through the powder dropping holes onto the first surface of the transfer medium. In this way, since the aperture values of the powder dropping holes are constant, the powder supply mechanism 2 can reliably and evenly supply hot melt powder to the first surface of the transfer medium.

[0028] Preferably, the heat transfer printing device further includes a heat preservation mechanism 4 and a heat transfer printing treatment mechanism 5 that are relatively located downstream of the powder shaking mechanism and the powder supply mechanism 2 in the conveying direction. The heat preservation mechanism 4 and the heat transfer printing treatment mechanism 5 have a spaced space in the vertical direction to heat the second surface and the first surface of the transfer medium that passes horizontally through the spaced space respectively. More specifically, the heat preservation mechanism 4 can use several heating lamps to heat the second surface, and the heat transfer printing treatment mechanism 5 can use the top surface of the following heat preservation box to heat the first surface. The heat transfer printing pattern and the hot melt powder are both heated so that the hot melt powder adhered to the heat transfer printing pattern melts and dries. In this way, the heat of the heat transfer printing treatment mechanism 5 can be fully utilized to heat the transfer medium, saving energy. Moreover, the heat transfer printing treatment mechanism 5 is arranged relatively close to both the powder shaking mechanism and the heat preservation mechanism 4, thus further optimizing the structural layout and reducing the space occupation.

[0029] Further preferably, the heat transfer device further comprises a finished product storage mechanism 9 for receiving and storing the finished transfer medium 300, the finished transfer medium 300 having a heat transfer pattern, and the conveying mechanism comprises a first guide roller 6, a second guide roller 7 and a third guide roller 8. With respect to the above conveying direction, the first guide roller 6 is used to guide the transfer medium to be conveyed toward the printing mechanism 1, the second guide roller 7 is used to guide the transfer medium to which the hot melt powder has been adhered to be conveyed toward the spacing space, and the third guide roller 8 is used to guide the transfer medium to be conveyed through the spacing space toward the finished product storage mechanism 9. Therefore, the heat transfer device can realize the return conveying of the transfer medium in the horizontal direction, which not only ensures the reliable conveying of the transfer medium, but also makes the overall structure of the heat transfer device compact, thereby facilitating the reduction of the occupied space in the horizontal direction.

[0030] Further preferably, the heat transfer device further comprises a cutter mechanism 10, which is located between the spacing space and the finished product storage mechanism 9 in the conveying direction, and is used to cut the predetermined area of ​​the transfer medium including the heat transfer pattern to obtain the finished transfer medium 300. Therefore, by providing the cutter mechanism 10, the heat transfer device can efficiently and automatically cut out the finished transfer medium 300, especially the finished transfer medium 300 of uniform size. In addition, the finished transfer medium 300 can also be cut manually, which reduces the cost but has low work efficiency.

[0031] Further preferably, the heat transfer processing mechanism 5 comprises a heat preservation box having an opening and an inner cavity, a heating plate arranged in the inner cavity, and a support frame 5.1 that moves in or out relative to the inner cavity through the opening, the support frame 5.1 that moves out relatively receives and supports the material 400 on which the finished transfer medium 300 is stacked, and the material 400 can be specifically a cloth such as clothes, and the support frame 5.1 that moves in relatively makes the heating plate abut against the finished transfer medium 300, so that the heat transfer pattern with the hot melt powder that has been melted and dried is heat-printed on the material 400. Specifically, the heating plate presses the finished transfer medium 300 on the clothes at 150-160°C for 10 seconds, and then the finished transfer medium 300 on the clothes is peeled off from the clothes, thereby completing the heat transfer. Therefore, by arranging the above-mentioned heat press processing mechanism 5 vertically below the heating mechanism of the heat press equipment, it is not only convenient to superimpose each transfer medium with a heat press pattern on each material 400 at a close distance, thereby saving time, but also the heat released by the heat press processing mechanism 5 to the outside world can be used to heat the transfer medium.

[0032] Further preferably, the printing mechanism 1, the heat preservation mechanism 4, and the heat transfer printing processing mechanism 5 are sequentially arranged at intervals relative to each other in the vertical direction. In the vertical direction, both the powder shaking mechanism and the powder feeding mechanism 2 are located between the printing mechanism 1 and the heat preservation mechanism 4. In the horizontal direction, relative to a vertical space that simultaneously accommodates the printing mechanism 1, the heat preservation mechanism 4, and the heat transfer printing processing mechanism 5, the powder shaking mechanism and the powder feeding mechanism 2 are located on one outer side of the vertical space, and the finished product storage mechanism 9 is located on the other opposite outer side of the vertical space. Therefore, the overall structural layout of the heat transfer printing device is reasonable. Not only do the projections of the printing mechanism 1, the heat preservation mechanism 4, and the heat transfer printing processing mechanism 5 at least partially overlap in the vertical direction, saving the space occupied in the horizontal direction, but also the transfer medium can pass horizontally and reversely between the printing mechanism 1 and the heat preservation mechanism 4 and between the heat preservation mechanism 4 and the heat transfer printing processing mechanism 5 in sequence. Thus, in the case where the transfer medium passes through both sides of the powder feeding mechanism 2 in a relatively reverse movement manner, the distance between the printing mechanism 1 and the heat preservation mechanism 4 in the vertical direction can be reduced, thereby saving the space occupied in the vertical direction, and thus saving the entire space occupied.

[0033] The working process is further described below in combination with the above-described embodiments of the heat transfer printing device of the present invention, and the material 400 is taken as an example of clothes. The transfer medium is unrolled from the material roller included in the conveying mechanism, first cut by the first guiding roller 6, and then passes through the position where the printing mechanism 1 is located. The printing mechanism 1 prints a pattern on the transfer medium. Subsequently, the transfer medium passes through the powder shaking mechanism employing two shaking rollers 3 and is naturally bent into a U-shaped portion. The powder feeding mechanism 2 is arranged on the inner side of the transfer medium of the U-shaped portion. The powder feeding mechanism 2 continuously supplies hot melt powder to the transfer medium, and the transfer medium adheres the hot melt powder to the part of the transfer medium printed with the heat transfer printing pattern while moving.

[0034] Under the shaking action of the two shaking rollers 3, the hot melt powder that is not adhered to the heat transfer printing pattern falls off from the surface of the transfer medium rising on the left side of the powder feeding mechanism 2 shown, that is, the left side portion of the U-shaped portion, and is deposited at the bottom of the U-shaped portion and adhered to the transfer medium conveyed from the right side. During this process, the powder feeding mechanism 2 replenishes the hot melt powder. Figure 1 The transfer medium after passing through the two shaking rollers 3 passes through the baking channel formed by the spaced space between the heat transfer printing processing mechanism 5 and the heat preservation mechanism 4, and then the transfer medium is cut into the finished transfer medium 300 by the cutting mechanism 10 and falls into the finished product storage mechanism 9.

[0035] The cut finished transfer medium 300 and the clothes are stacked together manually or automatically, and then are sent into the heat transfer printing processing mechanism 5 together. The heat transfer printing processing mechanism 5 transfers the heat transfer printing pattern on the product transfer medium to the clothes.
