[0002] Hot stamping, also known as heat transfer printing, generally involves first printing a pattern on a release film through a digital printer, then sprinkling hot melt powder on the release film through a powder shaking machine, cleaning the excess hot melt powder on the film outside the pattern through a powder shaking device, melting the hot melt powder on the pattern through a curing machine, and finally cooling to obtain a release film with a pattern. Finally, the pattern is transferred to the fabric by hot pressing with a hot stamping machine.

[0003] In the prior art, the powder control part of the powder shaking machine increases the weight of the release film by sprinkling more hot melt powder to prevent the release film from shaking left and right and damaging the printed pattern. However, this preventive measure has low efficiency, fast consumption of hot melt powder, and high powder adding frequency to the powder sprinkling box, thus increasing labor costs, low production efficiency, and high production costs.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right", "up", "down", "front", "rear" and similar expressions used herein are only for the purpose of illustration.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] Next, in combination with the drawings and specific implementation manners, the present invention will be further described:

[0032] As Figures 1 to 5 shown, an automatic positioning powder control device includes a rod-shaped rotating shaft 20 and positioning plates 30 located at both ends of the rotating shaft 20. The positioning plates 30 include vertically arranged groove-shaped sliding grooves 31, and both ends of the rotating shaft 20 are slidably sleeved with the sliding grooves 31.

[0033] One powder control plate 10 is arranged on each side of the rotating shaft 20. The powder control plate 10 includes a connection hole 11 sleeved with the rotating shaft 20. The outside of the connection hole 11 is provided with a cylindrical film pressing ring 12 coaxial with the connection hole 11, and the outside of the film pressing ring 12 is provided with a film blocking edge 13. A continuous powder blocking surface 14 is arranged between the film pressing ring 12 and the connection hole 11. The powder blocking surface 14 is provided with a high-position powder discharge hole 15 penetrating the powder blocking surface 14. The high-position powder discharge hole 15 is located between the film pressing ring 12 and the connection hole 11 and is not connected to the film pressing ring 12.

[0034] Further, the rotating shaft 20 is made of carbon fiber material.

[0035] In this embodiment, since the width of the release film can reach more than 1 meter, the rotating shaft 20 has a large length-diameter ratio. Using carbon fiber material to manufacture the rotating shaft 20 has the advantages of good straightness (up to 0.1 - 0.5 mm / m), light weight, and high strength.

[0036] Further, since the powder spraying device is usually located above the release film 40 and the powder control plate 10, during powder spraying and use, the hot melt powder 50 will inevitably enter between the film pressing ring 12 and the release film 40. To prevent the film pressing ring 12 of the powder control plate 10 from squeezing the hot melt powder 50 and causing deformation and deviation of the release film 40, an air clearance groove 16 recessed from the surface of the film pressing ring 12 is provided on the film pressing ring 12.

[0037] Further, a plurality of the air clearance grooves 16 are arranged in a circumferential array along the film pressing ring 12.

[0038] Further, to discharge the hot melt powder 50 that accidentally enters between the film pressing ring 12 and the release film 40 and avoid continuous extrusion of the hot melt powder 50 in a repeated cycle, a low-position powder discharge hole 17 penetrating through the film blocking edge 13 is provided at the connection between the film pressing ring 12 and the film blocking edge 13, and the low-position powder discharge hole 17 is communicated with the air clearance groove 16.

[0039] Further, to quickly discharge the hot melt powder 50 that accidentally enters between the film pressing ring 12 and the release film 40 during rotation, as shown in FIGS. Figure 2 、 3 、5, the air clearance groove 16 has a circular arc structure with a radius less than or equal to a semicircle. The center of the arc is close to the side of the film blocking edge 13. The top of the arc is close to but does not penetrate the powder blocking surface 14, and the two end points of the arc coincide with the film blocking edge 13.

[0040] In this embodiment, by making the center of the arc close to the side of the film blocking edge 13 and not connecting the air clearance groove 16 with the powder blocking surface 14, the side of the air clearance groove 16 close to the powder blocking surface 14 is the top of the arc. When approaching the low-position powder discharge hole 17, the arc gradually expands and is communicated with the low-position powder discharge hole 17, making the air clearance groove 16 open towards the side of the film blocking edge 13. Thus, during the rotation of the powder control plate 10 following the release film 40, the hot melt powder 50 moves gradually along the arc of the air clearance groove 16 towards the side of the film blocking edge 13 under the action of gravity until it is discharged outside the powder control plate 10 through the low-position powder discharge hole 17.

[0041] Moreover, by setting the air clearance groove 16 as a circular arc structure, good discharge effect of the hot melt powder 50 can be achieved regardless of the installation direction or rotation direction of the powder control plate 10.

[0042] In other embodiments, the clearance groove 16 can also be set to a triangle, with one side of the triangle coinciding with the film blocking edge 13. The triangular clearance groove also has a good powder discharging effect.

[0043] Further, in order to uniformly and quickly discharge the excessive hot melt powder 50 from the V-shaped bottom release film 40, two or more high-position powder discharging holes 15 are arranged in a circumferential array centered on the connecting hole 11.

[0044] Further, in order to keep the release film under a certain tension through the powder control plate 10, a counterweight block (not shown in the drawings) for adjusting the weight of the powder control plate 10 is arranged on the powder control plate 10.

[0045] Further, as Figure 3 、 5 shown, a powder guiding edge 18 covering the clearance groove 16 is arranged between the low-position powder discharging hole 17 and the high-position powder discharging hole 15. One side of the powder guiding edge 18 is connected to the high-position powder discharging hole 15, and the other side extends obliquely towards the low-position powder discharging hole 17 to the contour edge of the powder control plate 10.

[0046] In this embodiment, the powder guiding edge 18 covers the clearance groove 16. After the hot melt powder 50 is discharged from the high-position powder discharging hole 15, it is directly discharged to the outside of the powder control plate 10 along the inclined powder guiding edge 18.

[0047] Further, in order to prevent the rotating shaft 20 from getting stuck when lifting and sliding in the sliding groove 31, spherical heads 21 in the shape of spherical structures are respectively arranged at both ends of the rotating shaft 20, and the spherical heads 21 are slidably sleeved with the sliding groove 31.

[0048] Further, in order to facilitate the insertion of the rotating shaft 20 into the sliding groove 31 from top to bottom, a guide plate 32 extending towards the outside of the sliding groove 31 is arranged at the top of the sliding groove 31.

[0049] A powder shaking machine, as Figure 1 shown, a powder spreading device 60 is arranged above the automatic positioning powder control device.

[0050] The operation steps of the present invention are as follows:

[0051] 1. Sleeved two powder control plates 10 symmetrically on the rotating shaft 20;

[0052] 2. Adjust the distance between the film blocking edges 13 between the two powder control plates 10 according to the width of the release film 40, and then fix the two powder control plates 10 on the rotating shaft 20;

[0053] 3. Insert the rotating shaft 20 into the sliding groove 31 of the positioning plate 30, and test that the rotating shaft 20 can rotate smoothly and slide up and down in the sliding groove 31;

[0054] 4. Traverse the roll-shaped release film 40 under the lower part of the film pressing ring 12. Under the gravity of the powder control plate 10, a hot melt powder adsorption area with a "V" shape is formed on the release film 40. Under the action of the positioning plate 30 and the sliding groove, the hot melt powder adsorption area of the release film 40 can only move up and down, avoiding deviation in other directions and improving the adsorption stability of the hot melt powder.

[0055] 5. Start the powder sprinkling device 60 and sprinkle the hot melt powder 50 on the release film 40. The hot melt powder 50 accumulates at the bottom of the "V"-shaped release film 40.

[0056] 6. During the transmission of the roll-shaped release film 40, it continuously contacts the hot melt powder 50 accumulated at the bottom of the "V" shape, so that the hot melt powder 50 is adsorbed on the set area of the release film 40.

[0057] The hot melt powder 50 with a height higher than the high-position powder discharge hole 15 is discharged through the high-position powder discharge hole 15, so that the amount of hot melt powder in the hot melt powder adsorption area with a "V" shape remains stable.

[0058] The hot melt powder 50 accidentally entering between the film pressing ring 12 and the release film 40 is discharged through the low-position powder discharge hole 17.
