Description

Technical Field

[0001] The invention relates to the technical field of hot stamping mechanisms, in particular to a hot melt adhesive scraper mechanism for a hot stamping machine. Background Art

[0002] The hot stamping process on clothing with hot stamping machines is mainly electrochemical aluminum hot stamping foil, which mainly uses heating and pressure to transfer patterns or texts to the surface of the hot stamped material. The old hot stamping process uses oily hot stamping paste, which accumulates under the flower roller. The hot stamping paste is heated, and the flower roller is driven to rotate. The surface is attached with the heated hot stamping paste, which then heats the flower roller.

[0003] This type of glue will easily produce pungent exhaust gas when it evaporates when heated during use, which can easily affect the working environment. For this reason, hot melt adhesive is used instead of traditional oil-based hot stamping paste.

[0004] However, the scraper has a simple structure, and the hot melt adhesive needs to be replenished in time. The transmission method is manual addition, but manual addition is inconvenient to control the amount. Adding too little will affect the hot stamping effect, and adding too much will easily overflow and fall to the ground, causing unnecessary waste and polluting the working environment.

DETAILED DESCRIPTION

[0032] The embodiment of the present invention provides a hot melt adhesive scraper mechanism for a hot stamping machine, such as Figure 1-8 As shown, it is placed on the back of the frame 1, and a flower roller 12 is fixedly installed on the front of the frame 1, including a hollow scraper plate 2 inside. The entire scraper plate 2 is arranged obliquely, and an extension column 21 is welded to the end of the scraper plate 2, and the extension column 21 is connected to the frame 1. A slope 24 is provided in the upper half area of ​​the front of the scraper plate 2, and the lower half area of ​​the front of the scraper plate 2 is in conflict with the flower roller 12. A material injection box 6 is slidably fitted in the scraper plate 2, and a material injection tube 61 is fixedly installed at the bottom of the material injection box 6, and the material injection tube 61 extends to the back of the scraper plate 2.

[0033] It also includes multiple arc tubes 4, which are fixedly installed on the top of the scraper plate 2 at equal distances. Multiple spraying pipes are fixedly installed on the top of the injection box 6. The spraying pipes correspond to the arc tubes 4 one by one. The upper ends of the spraying pipes pass through the arc tubes 4 and face the slope 24.

[0034] A coating assembly is provided on the top of the scraper plate 2, which includes a paddle 8. The upper end of the paddle 8 is hinged to the top of the scraper plate 2. The coating assembly drives the paddle 8 to swing back and forth, so that the paddle 8 spreads the hot melt adhesive dripped on the slope 24 to all sides.

[0035] It also includes two side plates 3, which are symmetrically fixed on the left and right sides of the scraper plate 2, and two gratings 31 are fixedly installed on the opposite sides of the two side plates 3. The two gratings 31 are arranged up and down, and the front ends of the side edges 3 are in conflict with the left and right sides of the flower roller. The scraper plate 2, the flower roller 12, and the side plates 3 surround and conflict with each other to form a liquid accumulation groove that can accommodate hot melt adhesive.

[0036] During operation, after the hot melt adhesive is sprayed out from the injection tube of the injection box 6, it flows on the slope 24 of the scraper plate 2, and the hot melt adhesive contacts the paddle 8. Then, the smearing component drives the paddle 8 to swing back and forth slowly, so that the hot melt adhesive is evenly spread on the slope 24 and finally flows into the liquid accumulation tank. When the liquid level in the liquid accumulation tank rises to a certain height, the top grating 31 is blocked, and the hot melt adhesive is stopped from being sprayed. When the liquid level in the liquid accumulation tank drops to a certain level, the bottom grating 31 is exposed to the outside world, and the hot melt adhesive starts to be sprayed.

[0037] There is a pattern on the surface of the flower roller 12. The flower roller 12 is heated, and the hot melt adhesive penetrates into the pattern. At the same time, the flower roller 12 is in a rotating state. Since the flower roller 12 conflicts with the scraper plate 2, the purpose of scraping off excess hot melt adhesive is achieved, so that only the hot melt adhesive in the pattern exists on the surface of the flower roller 12, so that the flower roller 12 can be hot-stamped.

[0038] The smearing component includes multiple rotary switches 5 and multiple racks 43. The rotary switches 5 and the racks 43 correspond to the arc tube 4 one by one. The rotary switch 5 is fixedly installed on the top of the scraper plate 2. A support rod 51 is welded on the top of the rotary switch 5. A motor 52 is fixedly installed on the front section of the support rod 51. A gear 53 is welded on the transmission shaft of the motor 52. The rack 43 is arranged horizontally and slidably cooperates with the arc tube 4. The gear 53 meshes with the top of the rack 43, and the bottom of the rack 43 contacts the upper end of the paddle 8.

[0039] The arc tube 4 is bent into a semicircular ring shape, the paddle 8 is located directly below the arc tube 4, the rack 43 is located between the paddle 8 and the arc tube 4, a half gear 81 is welded on the upper end of the paddle 8, and the half gear 81 is meshed with the bottom of the rack 43. The motor 52 and the gear 53 cooperate to drive the rack 43 to move back and forth, and the rack 43 drives the paddle 8 to swing back and forth through the half gear 81.

[0040] The end of the injection box 6 is slidably matched with the inner wall of the scraper plate 2. A hose 62 is connected to the top of the injection box 6 spray pipe, and the hose 62 can pass through the arc tube 4. A plurality of motors 7 are connected to the bottom of the inner wall of the scraper plate 2. The motors 7 are arranged at equal distances. The transmission shaft of the motor 7 is vertically connected to a screw 71, and the screw 71 threadedly passes through the injection box 6.

[0041] The working end of the rotary switch 5 extends into the arc tube 4, and the upper end of the screw rod 71 is connected to the working end of the rotary switch 5. Figure 7 It can be seen that the motor 7 drives the screw 71 to rotate, so that the injection box 6 rises slowly. When the injection box 6 rises to a specified height, the screw 71 rotates a certain number of times, and the entire rotary switch is closed. At this time, the injection box 6 starts to work.

[0042] The rotary switch is composed of a sleeve, an upper conductive sheet 54, and a lower conductive sheet 55. The upper conductive sheet 54 is located above the lower conductive sheet 55. The upper conductive sheet 54 is slidably matched with the inner wall of the sleeve. The upper end of the screw 71 extends into the sleeve and is welded to the lower conductive sheet 55. Two thin ropes 56 are connected between the upper conductive sheet 54 and the lower conductive sheet 55. When the screw 71 rotates, the two thin ropes 56 are entangled together. When the screw 71 is twisted to a certain extent, the two conductive sheets contact each other, thereby achieving the effect of closing the switch.

[0043] A connecting rod 41 is welded between two adjacent arc tubes 4 , a hoop is welded at the front end of the support rod 51 , the connecting rod 41 passes through the hoop, the front end of the arc tube 4 faces the slope 24 , and the rear end of the arc tube 4 is connected to the scraper plate 2 .

[0044] Slide bars 42 are symmetrically welded on both sides of the front end of the arc tube 4 . A slide groove 431 is formed along the length direction of the rack 43 . The slide bars 42 and the slide groove 431 are slidably matched.

[0045] The frame 1 is provided with a through slot 11, and an extension column 21 passes through the through slot 11 at one end away from the scraper plate 2, and a handle 22 is fixedly installed thereon. A through slot 23 adapted to the injection tube 61 is provided on the back of the scraper plate 2, and the injection tube 61 extends to the outside of the scraper plate 2 through the through slot 23. The frame 1 is threadedly connected with a screw rod 13, which extends into the through slot 11 and conflicts with the extension column 21.

[0046] In summary, the hot melt adhesive scraper mechanism for the hot stamping machine has side plates 3 at both ends of the scraper plate 2, and the scraper plate 2, the pattern roller 12, and the side plates 3 cooperate to surround each other to form a liquid accumulation groove for receiving the hot melt adhesive. Since the scraper plate 2 is in contact with the pattern roller 12, the scraper plate 2 removes excess hot melt adhesive during the rotation of the pattern roller 12, and the hot melt adhesive penetrates into the surface pattern, replacing the traditional oily hot stamping paste to cover the entire pattern roller 12, which is cleaner to use.

[0047] In addition, a filling box 6 is set up in the scraper plate 2, and an arc tube 4, a paddle 8 and a smearing component are set up on the top of the scraper plate 2. The smearing component is composed of a paddle 8, a motor 52, a gear 53, and a half gear 81. The spray pipe of the filling box 6 is guided to the surface of the scraper plate 2 through the arc tube 4, so that the hot melt adhesive sprayed from the filling box 6 drips onto the scraper plate 2. The side plate 3 is connected to the grating 31, and the filling box 6 is controlled by the grating 31 to inject hot melt adhesive into the liquid accumulation tank, replacing the traditional manual operation, achieving the purpose of automatic addition, facilitating the control of the amount of hot stamping material added, and playing a role in reducing resource waste.
