Description

Technical Field

[0001] The present invention relates to white ink heat transfer printing technology, and particularly to a combined powder shaking machine. Background Art

[0002] White ink heat transfer is a common heat transfer technology, usually used for transferring patterns or designs onto various fabrics or other materials, especially in the fields of clothing, household items, ornaments, etc.

[0003] When a heat transfer printer is working, it first prints a pattern on a heat transfer film, then uses a powder shaking machine to sprinkle hot melt powder onto the heat transfer film with the printed pattern, and shakes off the excess hot melt powder, so that the hot melt powder adheres to the pattern on the heat transfer film. Finally, a heating device is used to heat and melt the hot melt powder on the pattern of the heat transfer film, so that the hot melt powder firmly adheres to the heat transfer film.

[0004] Common powder shaking machines can sprinkle powder smoothly onto the heat transfer film after heat printing. However, after the excess hot melt powder is shaken off, it will accumulate at the bottom of the remaining part of the heat transfer film and requires manual cleaning. For example, in the utility model patent with the application number 202223470519.5, it discloses a recyclable powder shaking device. After powder sprinkling, the back of the heat transfer film is slapped by the rotation of powder shaking blades, so that the excess hot melt powder attached to its surface can be detached from its surface. However, in the actual application process, most of the slapped hot melt powder will accumulate at the bottom bending part of the heat transfer film, and only a small part will directly fall into the collection box at the bottom, so that subsequent manual cleaning is still required. And for example, in a powder shaking and printing all-in-one machine disclosed in a Chinese invention patent with the application number 202410884807.X, through a blowing pipe arranged at the bending part of the powder shaking part of the release film, during operation, it can blow the powder accumulated at the bending part. However, as the distance increases, the thrust of the gas blown out by the blowing pipe decreases sharply. At the same time, too much blowing force will also cause the hot melt powder to fly everywhere, thus not only resulting in poor collection effect of the hot melt powder, but also causing waste of the hot melt powder. Summary of the Invention

[0005] The purpose of the present invention is to provide a combined powder shaking machine to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A combined powder shaking machine, comprising a box body and a feeding guide roller and a feeding guide roller arranged at both ends of the inner wall of the box body. A heat transfer film is arranged between the feeding guide roller and the feeding guide roller. A powder feeding unit is arranged at the top of the box body, and the powder feeding unit includes a powder storage box; Vibration motors are installed on both sides of the powder storage box. Mounting brackets are symmetrically installed on both sides of the bottom of the powder storage box. A vibration guide roller is installed between the two mounting brackets. A surplus part is arranged on the drawing film between the vibration guide roller and the feeding guide roller. An arc part is formed by the free sagging of the bottom of the surplus part. A discharge screw blade is arranged on the inner wall of the box body. The discharge screw blade is driven by a motor. There is a gap between the discharge screw blade and the bottom of the upper surface of the arc part; An inclined discharge chute is opened at the bottom of the box body. Inclined guiding surfaces are arranged on both sides of the inclined discharge chute inside the box body. A guide box corresponding to the inclined discharge chute is arranged outside the box body.

[0007] Furthermore, the distance value range between the discharge screw blade and the bottom of the upper surface of the arc part is 4 mm to 7 mm.

[0008] Furthermore, a semi-circular groove is arranged at the bottom of the powder storage box. An auxiliary auger is arranged along the length direction inside the semi-circular groove. The auxiliary auger is driven by a motor. A plurality of powder discharge holes are opened at the bottom of the semi-circular groove.

[0009] Furthermore, fixing plates are installed at the bottoms of the two mounting brackets. The two ends of the fixing plate are respectively connected with a first connecting plate and a second connecting plate. The vibration guide roller is rotatably connected between the two first connecting plates on both sides. An auxiliary guide roller is rotatably connected between the two second connecting plates on both sides. The vibration guide roller and the auxiliary guide roller are symmetrically arranged on both sides of the fixing plate. The drawing film sequentially passes through the feeding guide roller, the vibration guide roller, the auxiliary guide roller and the feeding guide roller.

[0010] Furthermore, the axis of symmetry between the vibration guide roller and the auxiliary guide roller, the central axis of the discharge screw blade and the central axis of the arc part are all in the same vertical plane.

[0011] Furthermore, a compensation part is arranged on the side of the drawing film close to the powder storage box. One end of the compensation part close to the arc part is inclined downward.

[0012] Furthermore, moving grooves are opened on both sides of the fixing plate. The first connecting plate and the second connecting plate are respectively slidably connected in the moving grooves on both sides. A linkage gear is rotatably connected to the inner side surface of the fixing plate. Tooth teeth are arranged on the sides of the first connecting plate and the second connecting plate close to the linkage gear. The first connecting plate and the second connecting plate are respectively meshed on both sides of the linkage gear through the tooth teeth. Anti-slip rubber pads are arranged on the sides of the first connecting plate and the second connecting plate far from the linkage gear.

[0013] Furthermore, the anti-slip rubber pad is slidably connected to the inner wall of the moving groove, and the thrust value applied by the drawing film to the vibration guide roller and the auxiliary guide roller is less than the sliding friction value between the anti-slip rubber pad and the inner wall of the moving groove.

[0014] Furthermore, adjusting cylinders are installed on both sides of the inner wall of the box. Connecting seats are fixedly connected to the bottoms of the telescopic ends of the adjusting cylinders on both sides. Limiting guide frames adapted to the connecting seats are symmetrically arranged on both sides of the inner wall of the box, and the inner sides of the connecting seats are slidably connected to the limiting guide frames.

[0015] Furthermore, the discharge spiral blade is rotatably connected between the connecting seats on both sides.

[0016] Compared with the prior art, a combined powder shaking machine provided by the present invention has the following beneficial effects: 1. In this combined powder shaking machine, through the mutual cooperation among the mounting frame, vibration guide rollers, vibration motors, arc parts, discharge spiral blades and inclined discharge chutes, the excess hot melt powder converged on the painting film can be effectively cleaned and collected during the working process of the powder shaking machine, preventing the painting film from being damaged due to excessive accumulation of hot melt powder, and at the same time, there is no need for later manual cleaning, making the powder shaking machine more convenient to use; 2. In this combined powder shaking machine, through the synergistic effect of the vibration guide rollers and the auxiliary guide rollers, the shape of the bottom arc part is more regular and can better match the shape of the discharge spiral blade, so that the discharge spiral blade can better discharge the hot melt powder converged in the arc part during rotation; 3. In this combined powder shaking machine, through the mutual cooperation among the compensation part, vibration guide rollers, auxiliary guide rollers, first connecting plate, second connecting plate, teeth and linkage gears, the inclination angle of the compensation part can be adjusted during the working process, so that when powder is sprinkled on different-sized patterns, the excess hot melt powder above can slide down and contact the pattern after powder sprinkling again, thereby effectively supplementing the hot melt powder on the pattern, ensuring uniform coverage of the hot melt powder at the edge of the pattern, avoiding color difference or wire breakage phenomena, and improving the clarity and aesthetics of the overall pattern; 4. In this combined powder shaking machine, through the mutual cooperation among the adjusting cylinders, connecting seats and limiting guide frames, the position height of the discharge spiral blade can be adjusted after the compensation part is adjusted, so that the position height of the discharge spiral blade can always match the arc part, thus not affecting its discharging work.

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. Embodiment

[0030] Please refer to Figures 1-9 , a combined powder shaking machine, including a box body 1 and a feeding guide roller 101 and a feeding guide roller 102 arranged at both ends of the inner wall of the box body 1. A film drawing 103 is arranged between the feeding guide roller 101 and the feeding guide roller 102. A powder feeding unit is arranged at the top of the box body 1, and the powder feeding unit includes a powder storage box 2; Vibration motors 3 are installed on both sides of the powder storage box 2. Mounting brackets 31 are symmetrically installed on both sides of the bottom of the powder storage box 2. A vibration guide roller 32 is installed between the two mounting brackets 31. A surplus part 33 is provided on the film 103 between the vibration guide roller 32 and the feeding guide roller 102. An arc part 34 is formed by the free hanging of the bottom of the surplus part 33. A discharge screw blade 35 is provided on the inner wall of the box body 1. The discharge screw blade 35 is driven by a motor. There is a gap between the discharge screw blade 35 and the bottom of the upper surface of the arc part 34. An inclined discharge chute 36 is formed at the bottom of the box body 1. Inclined guiding surfaces 37 are provided on both sides of the inclined discharge chute 36 inside the box body 1. A guiding box 38 corresponding to the inclined discharge chute 36 is provided outside the box body 1.

[0031] It should be noted that the guiding box 38 can be connected to an external material lifting mechanism, which can be a lifting auger or a lifting conveyor belt, etc. And the above-mentioned material lifting mechanisms are all existing equipment and can be purchased. Through the external material lifting mechanism, the collected hot melt powder can be conveyed back to the powder storage box 2 again, so that the hot melt powder can be recycled and the production efficiency can be improved.

[0032] In this embodiment, the distance value range between the discharge screw blade 35 and the bottom of the upper surface of the arc part 34 is 4 mm to 7 mm. During the actual working process, there is always a certain amount of hot melt powder on the arc part 34, which can provide pressure to the arc part 34, so that the arc part 34 is not likely to have a large position shift during vibration and can maintain a relatively stable state. At the same time, it also makes the discharge screw blade 35 not directly contact the film 103, thus effectively avoiding the situation that the discharge screw blade 35 rubs against the surface of the film 103 too much during rotation, resulting in serious wear of the surface of the film 103.

[0033] In this embodiment, a semi-circular groove 21 is provided at the bottom of the powder storage box 2. An auxiliary auger 22 is arranged along the length direction inside the semi-circular groove 21. The auxiliary auger 22 is driven by a motor. A plurality of powder discharge holes 23 are formed at the bottom of the semi-circular groove 21. Through the arrangement of the auxiliary auger 22, it can stir the hot melt powder in the semi-circular groove 21, so that the normal discharge of the hot melt powder is not blocked, and the situation of blockage of the powder discharge holes 23 can be effectively avoided. In addition, through the coordinated use of the vibration motor 3, the powder storage box 2 can be vibrated synchronously, thereby further ensuring the smooth operation of the powder discharge holes 23.

[0034] During the working process, the printed pattern on the film 103 moves synchronously as the film 103 moves. When it passes below the powder discharge hole 23, powder is continuously discharged at the powder discharge hole 23, so that the discharged hot melt powder can adhere to the surface of the printed pattern, forming a uniform and delicate powder layer. During this process, the vibration motor 3 continuously vibrates and drives the mounting frame 31 and the vibration guide roller 32 to vibrate, so that the vibration guide roller 32 can drive the film 103 to vibrate locally, thereby shaking off the excess hot melt powder adhering to its surface and converging it at the arc portion 34 at its bottom. At this time, the discharge screw blade 35 is always in a rotating state, and during its rotation, it can convey the hot melt powder converged at the arc portion 34 to one side of the film 103, so that it can be discharged from its side and fall into the inclined discharge chute 36, and finally discharged from the guide box 38 at the end of the inclined discharge chute 36. Embodiment

[0035] Please refer to Figure 3 、 Figures 8-10 In this embodiment, on the basis of the above embodiment, a technical solution is provided: Fixing plates 4 are installed at the bottoms of the two mounting frames 31. The two ends of the fixing plate 4 are respectively connected with a first connecting plate 41 and a second connecting plate 42. The vibration guide roller 32 is rotatably connected between the two first connecting plates 41 on both sides. An auxiliary guide roller 43 is rotatably connected between the two second connecting plates 42 on both sides. The vibration guide roller 32 and the auxiliary guide roller 43 are symmetrically arranged on both sides of the fixing plate 4. The film 103 passes through the feeding guide roller 101, the vibration guide roller 32, the auxiliary guide roller 43 and the feeding guide roller 102 in sequence.

[0036] It should be added that the axis of symmetry between the vibration guide roller 32 and the auxiliary guide roller 43, the central axis of the discharge screw blade 35 and the central axis of the arc portion 34 are all in the same vertical plane. Through the synergistic effect of the vibration guide roller 32 and the auxiliary guide roller 43, the shape of the bottom arc portion 34 is more regular and can better match the shape of the discharge screw blade 35, so that the discharge screw blade 35 can better discharge the hot melt powder converged at the arc portion 34 during rotation. Embodiment

[0037] Please refer to Figure 3 、 Figures 5-6 、 Figure 10 In this embodiment, on the basis of the above embodiment, a technical solution is provided: A compensation portion 5 is provided on the side of the film 103 close to the powder storage box 2, and one end of the compensation portion 5 close to the arc portion 34 is inclined downward.

[0038] In this embodiment, moving grooves 51 are formed on both sides of the fixed plate 4. The first connecting plate 41 and the second connecting plate 42 are respectively slidably connected in the moving grooves 51 on both sides. A linkage gear 52 is rotatably connected to the inner side surface of the fixed plate 4. Tooth teeth 53 are provided on one side of the first connecting plate 41 and the second connecting plate 42 close to the linkage gear 52. The first connecting plate 41 and the second connecting plate 42 are respectively meshed on both sides of the linkage gear 52 through the tooth teeth 53. Anti-slip rubber pads 54 are provided on one side of the first connecting plate 41 and the second connecting plate 42 away from the linkage gear 52.

[0039] It should be added that the anti-slip rubber pad 54 is slidably connected to the inner wall of the moving groove 51, and the thrust value exerted by the drawing film 103 on the vibration guide roller 32 and the auxiliary guide roller 43 is less than the sliding friction value between the anti-slip rubber pad 54 and the inner wall of the moving groove 51, so that the vibration guide roller 32 and the auxiliary guide roller 43 can always maintain a relatively stable state during normal operation.

[0040] In this embodiment, adjusting cylinders 55 are installed on both sides of the inner wall of the box body 1. The bottoms of the telescopic ends of the two adjusting cylinders 55 are fixedly connected with connecting seats 56. Limiting guide frames 57 adapted to the connecting seats 56 are symmetrically arranged on both sides of the inner wall of the box body 1. The connecting seats 56 are slidably connected to the inner side surfaces of the limiting guide frames 57. The discharging spiral blade 35 is rotatably connected between the two connecting seats 56.

[0041] During the working process, when processing drawing films 103 with different pattern sizes, by pulling the vibration guide roller 32 and the auxiliary guide roller 43, the distance between the two is changed, so that the inclination angle of the compensation part 5 can be adjusted. When the pattern after powder spreading reaches the position of the compensation part 5, through the vibration of the vibration guide roller 32, the excess hot melt powder above can slide downwards and pass through the pattern part again, thereby effectively supplementing the hot melt powder on the pattern, ensuring uniform coverage of the hot melt powder at the pattern edge, avoiding color difference or broken line phenomena, and improving the clarity and beauty of the overall pattern.

[0042] In addition, after the inclination angle of the compensation part 5 changes, the position of the arc part 34 changes synchronously. At this time, the connecting seat 56 is driven by the adjusting cylinder 55 to move vertically, so that the position height of the discharging spiral blade 35 can be adjusted, and the normal discharging work of the discharging spiral blade 35 is not affected.

[0043] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
