Technical Field

[0001] This utility model relates to the field of powder shaking machine technology, and in particular to a positioning and powder control device for a powder shaking machine. Background Technology

[0002] Heat transfer printing, also known as heat printing, generally involves printing a pattern onto a release film using a digital printer, then applying hot melt powder onto the release film using a powder shaker, cleaning off any excess powder outside the pattern using a powder shaker, then heating the film in a curing machine to melt the hot melt powder onto the pattern, cooling it to obtain a release film with the pattern, and finally transferring the pattern onto the fabric using a heat transfer machine.

[0003] In existing technologies, the powder control part of the powder shaker increases the weight of the release film by sprinkling in more hot melt powder to prevent the release film from shaking left and right and damaging the printed pattern. However, this prevention method is inefficient, the hot melt powder is consumed quickly, and the powder dispensing box needs to be refilled frequently, which increases labor costs, production efficiency and production costs.

[0004] Therefore, there is an urgent need to design a positioning and powder control device for a powder shaking machine, so that the position of the release film can be moved in a controllable manner, thereby improving the adsorption stability of hot melt powder. Utility Model Content

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0029] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," "up," "down," "front," "back," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0032] like Figures 1-5 As shown, a positioning and powder control device for a powder shaking machine 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 grooves 31 in the shape of concave grooves, and the two ends of the rotating shaft 20 are respectively slidably sleeved with the grooves 31.

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

[0034] Furthermore, 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 shaft 20 has a large length-to-diameter ratio. The shaft 20 is made of carbon fiber material, which has the advantages of good straightness (up to 0.1~0.5mm / m), light weight, and high strength.

[0036] Furthermore, since the powder application device is usually located above the release film 40 and the powder control plate 10, during powder application and use, the hot melt powder 50 will inevitably enter between the pressure ring 12 and the release film 40. In order to prevent the pressure ring 12 of the powder control plate 10 from squeezing the hot melt powder 50 and causing the release film 40 to deform and shift, the pressure ring 12 is provided with a relief groove 16 recessed on the surface of the pressure ring 12.

[0037] Furthermore, several of the clearance grooves 16 are arranged in a circular array along the circumference of the pressure ring 12.

[0038] Furthermore, in order to discharge the hot melt powder 50 that accidentally enters between the pressure ring 12 and the release film 40 and to avoid the continuous compression of the hot melt powder 50 through repeated cycles, a low-level powder discharge hole 17 is provided at the connection between the pressure ring 12 and the film-blocking edge 13, which passes through the film-blocking edge 13. The low-level powder discharge hole 17 is connected to the anti-cavity groove 16.

[0039] Furthermore, in order to quickly remove the hot melt powder 50 that accidentally enters between the pressure ring 12 and the release film 40 during rotation, such as... Figure 2 , 3 As shown in Figure 5, the clearance groove 16 has an arc-shaped structure that is less than or equal to a semicircle. The center of the arc is close to the side of the baffle edge 13, the top of the arc is close to but does not penetrate the powder-blocking surface 14, and the two ends of the arc coincide with the baffle edge 13.

[0040] In this embodiment, by making the center of the arc close to the side of the baffle edge 13 and the clearance groove 16 not connected to the powder blocking surface 14, the side of the clearance groove 16 near the powder blocking surface 14 is made to have an arc-shaped top. As it approaches the low-position powder discharge hole 17, the arc gradually expands and connects with the low-position powder discharge hole 17, so that the clearance groove 16 is in an open state towards the side of the baffle edge 13. Thus, as the powder control disk 10 rotates with the release film 40, the hot melt powder 50 gradually moves towards the side of the baffle edge 13 along the arc of the clearance groove 16 under the action of gravity, until it is discharged from the outside of the powder control disk 10 through the low-position powder discharge hole 17.

[0041] Furthermore, by setting the clearance groove 16 to an arc-shaped structure, the powder control plate 10 can achieve a good hot melt powder 50 discharge effect regardless of the installation direction or rotation direction.

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

[0043] Furthermore, in order to ensure that the excess hot melt powder 50 of the V-shaped bottom release film 40 is discharged evenly and quickly, there are two or more high-position powder discharge holes 15 arranged in a circumferential array with the connecting hole 11 as the center.

[0044] Furthermore, in order to maintain a certain tension on the release film through the powder control plate 10, a counterweight (not shown in the drawings) is provided on the powder control plate 10 to adjust the weight of the powder control plate 10.

[0045] Furthermore, such as Figure 3 , 5 As shown, a powder guiding edge 18 covering the void groove 16 is provided between the low-position powder discharge hole 17 and the high-position powder discharge hole 15. One side of the powder guiding edge 18 is connected to the high-position powder discharge hole 15, and the other side extends obliquely towards the low-position powder discharge hole 17 to the contour edge of the powder control plate 10.

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

[0047] Furthermore, in order to prevent the rotating shaft 20 from getting stuck when it slides up and down in the slide groove 31, each end of the rotating shaft 20 is provided with a ball head 21 with a spherical structure, and the ball head 21 is slidably sleeved with the slide groove 31.

[0048] Furthermore, in order to facilitate the insertion of the rotating shaft 20 into the slide groove 31 from top to bottom, a guide plate 32 extending outward from the top of the slide groove 31 is provided.

[0049] A type of powder shaking machine, such as Figure 1As shown, it includes a powder-spraying device 60 disposed above the positioning and powder-controlling device.

[0050] The operation steps of this utility model are as follows:

[0051] 1. Insert the two powder control discs 10 symmetrically into the rotating shaft 20;

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

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

[0054] 4. The roll release film 40 is pulled through from below the pressure ring 12. Under the gravity of the powder control plate 10, the release film 40 forms a hot melt powder adsorption area with a "V" shape. 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 displacement in other directions and improving the hot melt powder adsorption stability.

[0055] 5. Start the powder spreading device 60 to spread the hot melt powder 50 onto the release film 40. The hot melt powder 50 accumulates at the bottom of the "V"-shaped release film 40.

[0056] 6. During the conveying process, the roll release film 40 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 designated area of ​​the release film 40.

[0057] Hot melt powder 50, which is higher than the high-level powder discharge hole 15, is discharged through the high-level powder discharge hole 15, forming a "V" shape.

[0058] The amount of hot melt powder in the hot melt powder adsorption region of the shaped structure remains stable;

[0059] Hot melt powder 50 that accidentally enters between the pressure ring 12 and the release film 40 is discharged through the low-position powder discharge hole 17.

[0060] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
