Description

Technical Field

[0001] This invention relates to the field of hot stamping equipment technology, and in particular to a heat transfer hot stamping equipment. Background Technology

[0002] Hot stamping is a special printing process that does not use ink. It mainly utilizes the principle of heat transfer. Under pressure, the hot stamping foil comes into contact with the stamping plate and the substrate. The heating plate generates heat, which melts the thermoplastic dyeing resin layer and adhesive. The adhesive strength of the dyeing resin layer decreases, while the special heat-sensitive adhesive increases after melting. The aluminum layer is transferred to the substrate while being separated from the hot stamping foil base film. As the pressure is released, the adhesive cools and solidifies rapidly, and the aluminum layer adheres firmly to the substrate, completing the hot stamping process.

[0003] Currently, in the manufacturing process of the round cover plate for drum washing machines, a layer of aluminum is often manually printed on its outer contour surface to improve its aesthetic appearance. However, while existing hot stamping equipment can stamp the aluminum layer, it can only perform simple stamping on flat surfaces of the substrate and cannot effectively stamp the curved surfaces of annular substrates (the outer contour surface of the drum washing machine's round cover plate). Therefore, to improve the efficiency of aluminum layer printing on the round cover plate of drum washing machines, there is an urgent need for a hot stamping device that can automatically stamp the aluminum layer on the outer contour surface of the drum washing machine's round cover plate.

The automatic rotating clamping mechanism 3 includes a chassis 31 fixed inside the cabinet 1, a hydraulic telescopic cylinder 32 vertically fixed inside the chassis 31, a lifting platform 33 fixedly installed at the top of the piston rod of the hydraulic telescopic cylinder 32, a rotating shaft 34 rotatably installed at the top of the lifting platform 33 and extending through the top of the chassis 31, a rotating device 35 that drives the rotating shaft 34 to rotate, a lower clamping plate 36 fixed on the rotating shaft 34, a fixed shaft 37 vertically fixed inside the cabinet 1 and suspended above the lower clamping plate 36, and an upper clamping plate 38 rotatably connected to the fixed shaft 37 and parallel to the lower clamping plate 36. The lower clamping plate 36 and the upper clamping plate 38 are located in front of the hot stamping roller 26 and clamp and fix the round cover plate of the drum washing machine. The outer contour surface of the hot stamping roller 26 can roll contact with the outer contour surface of the round cover plate of the drum washing machine. A suspension beam 11 connected to the upper end of the fixed shaft 37 is fixedly installed inside the cabinet 1. The automatic loading and unloading mechanism 4 includes a pair of parallel sliding plates 41 slidably disposed on the top of the housing 31, a moving device 42 that drives the two sliding plates 41 to slide closer or further away from each other, and a pair of belt conveying devices 43 horizontally mounted on the two sliding plates 41. The two sliding plates 41 are located on the front and rear sides of the lower clamping plate 36, and the opposite sides of the two sliding plates 41 are respectively provided with notches 411 for the two sides of the lower clamping plate 36 to extend into. The two belt conveying devices 43 are respectively parallel to each other in the middle of the two sliding plates 41, and can clamp and convey the drum washing machine cover plate on the lower clamping plate 36.

[0020] like Figure 6As shown, the sliding frame 24 is rotatably mounted on both sides of the hot stamping roller 26, with multiple tension rollers 241 respectively. Support discs 271 for supporting the electroplated aluminum film are fixedly mounted on the unwinding roller 27 and the take-up roller 28, respectively. A pair of positioning discs for positioning the electroplated aluminum film are fixedly mounted on the tension rollers 241. By employing the aforementioned tension rollers 241, support discs 271, and positioning discs, not only can the stability of the unwinding and take-up of the electroplated aluminum film be effectively ensured, but also the electroplated aluminum film can be accurately and effectively clamped between the hot stamping roller 26 and the outer contour surface of the drum washing machine's round cover plate, thereby effectively improving the hot stamping quality of this equipment.

[0021] like Figure 5 As shown, a circular groove 361 is formed in the center of the top of the lower clamping plate 36, and a circular protrusion 381 is fixedly provided in the center of the bottom of the upper clamping plate 38, which movably inserts into the circular groove 361. The outer diameter of the circular protrusion 381, the inner diameter of the circular groove 361, and the inner diameter of the drum washing machine cover plate are the same. By using the above-mentioned circular groove 361 and circular protrusion 381, the upper clamping plate 38 and the lower clamping plate 36 can stably and accurately clamp and fix the drum washing machine cover plate, thereby ensuring that the hot stamping roller 26 can wrap the electroplated aluminum film and make uniform contact with the outer contour surface of the drum washing machine cover plate.

[0022] like Figure 3 As shown, the cabinet 1 is provided with an automatic supply device 6 and an automatic storage device 7 on both sides of the chassis 31 for supplying and storing the round cover plates of the drum washing machine.

The automatic storage device 7 includes a pair of vertically parallel rotating shafts 71 rotatably mounted on the inner wall of the cabinet 1, two pairs of sprockets 72 respectively fixedly mounted on the two rotating shafts 71, two vertically parallel chains 73 respectively sleeved and mounted on the two pairs of sprockets 72, multiple pairs of horizontally parallel storage plates 74 respectively evenly fixed on the two chains 73, and a servo motor 75 fixedly mounted on the cabinet 1 with its output end connected to a rotating shaft 71. The supply plate 64 and the storage plate 74 are symmetrically located on both sides of the chassis 31 and are parallel to each other below the two sliding plates 41.

By using the above-mentioned positioning posts 641 and 741, the drum washing machine cover plate can be accurately positioned in the middle of the two supply plates 64 and the two storage plates 74, thereby effectively cooperating with the two sliding plates 41 to stably transfer the drum washing machine cover plate.

[0024] like Figure 1 , Figure 3 As shown, rectangular openings 12 are provided on both sides of the cabinet 1. A rectangular frame 13 is fixedly installed around the rectangular openings 12 in the cabinet 1. The rectangular frame 13 is located inside the cabinet 1. Servo motor 65 or servo motor 75 is fixedly installed on the outer wall of the rectangular frame 13. The two ends of the rotating shaft 61 or rotating shaft 71 are respectively rotatably connected to the inner wall of the rectangular frame 13, and one end rotatably passes through the side wall of the rectangular frame 13 to connect to the output end of servo motor 65 or servo motor 75. By using the rectangular openings 12 and the rectangular frame 13, it is not only convenient to install and support the various components in the automatic supply device 6 and automatic storage device 7, but also to utilize the space outside the cabinet 1 to ensure the safe operation of the automatic supply device 6 and automatic storage device 7.

[0025] like Figure 2 As shown, the lead screw lifting device 23 includes a linear guide rail 231 vertically fixed on the base 21, a lead screw 232 vertically rotatably mounted on the linear guide rail 231, a nut 233 sliding on the linear guide rail 231 and threadedly connected to the lead screw 232, and a servo motor 234 fixed on the linear guide rail 231 and driving the lead screw 232 to rotate.

By employing the aforementioned lead screw lifting device 23 and lead screw moving device 25, not only can the hot stamping roller 26 and the electroplated aluminum film be evenly hot stamped on the outer contour surface of the drum washing machine cover, but by controlling the lead screw lifting device 23 and the lead screw moving device 25, the height and horizontal position of the hot stamping roller 26 can also be adjusted, thereby adapting to drum washing machine cover plates of different diameters and thicknesses to a certain extent.

[0026] like Figure 5 , Figure 6As shown, the rotating device 29 includes a servo motor 291 fixedly mounted on the sliding frame 24, a drive gear 292 fixedly mounted on the servo motor 291, and a pair of driven gears 293 that simultaneously mesh with the drive gear 292 and are respectively fixedly connected to the hot stamping roller 26 and the take-up roller 28. A U-shaped mounting bracket 294U for mounting the servo motor 291 is fixedly provided at the bottom of the sliding frame 24. The drive gear 292 and the driven gear 293 are located at the bottom of the sliding frame 24 and mesh. The hot stamping roller 26 and the take-up roller 28 are located at the top of the sliding frame 24, and the lower ends of the hot stamping roller 26 and the take-up roller 28 respectively rotate through the sliding frame 24 and connect to the two driven gears 293. The rotating device 35 includes a worm gear 351 fixed to the lower end of the rotating shaft 34, a worm 352 rotatably mounted on the lifting platform 33 and meshing with the worm gear 351, and a servo motor 353 fixed on the lifting platform 33 and driving the worm 352 to rotate. The lifting platform 33 is hollow inside, and the worm gear 351 and worm 352 are located inside the lifting platform 33 and mesh for transmission. The servo motor 353 is fixedly installed outside the lifting platform 33, and one end of the worm 352 rotates out of the inner wall of the lifting platform 33 and connects to the output end of the servo motor 353. The lower end of the rotating shaft 34 rotates from the top wall of the lifting platform 33 and enters its interior, and is fixedly connected to the worm gear 351.

[0027] By adopting the above-mentioned technical solutions, rotating device 29 and rotating device 35 can not only effectively drive the hot stamping roller 26, the take-up roller 28 and the rotating shaft 34 to rotate, but also the gear transmission structure in rotating device 29 and the worm gear 351 and worm 352 transmission structure in rotating device 35 can make the hot stamping roller 26 and the take-up roller 28 rotate synchronously and the rotating shaft 34 rotate self-locking. In addition, in conjunction with other components of this equipment, the hot stamping processing of the round cover of the drum washing machine can be stably realized.

[0028] like Figure 4As shown, the moving device 42 includes a pair of U-shaped plates 421 that are parallel to each other and fixed to the top of the chassis 31; a pair of rotating shafts 422 that are parallel to each other and rotate perpendicularly through the two U-shaped plates 421; a servo motor 423 that drives one of the rotating shafts 422 to rotate; two pairs of sprockets 424 that are respectively fixedly mounted on the two rotating shafts 422; two chains 425 that are sleeved and mounted on the two pairs of sprockets 424; a pair of sliders 426 that are fixed to the bottom of one sliding plate 41 and slide on the two U-shaped plates 421 respectively; and a pair of sliders 426 that are respectively fixed to the bottom of another sliding plate 41 and slide on the two U-shaped plates 421 respectively. Slider 427, which moves on the two U-shaped plates 421, two pairs of sprockets 424 and two chains 425 are located inside the U-shaped plates 421. The two U-shaped plates 421 and the two sliding plates 41 intersect perpendicularly, and the lower clamping plate 36 is located between the two U-shaped plates 421. Slider 426 and slider 427 on the U-shaped plates 421 are respectively fixedly connected to the opposite parts of the chains 425. Servo motor 423 is fixedly installed on the side wall of one U-shaped plate 421, and the rotating shaft 422 extends out of the U-shaped plate 421 and is fixedly connected to the output end of servo motor 423. By using the above-mentioned moving device 42, not only can it cooperate with the automatic supply device 6 and the automatic storage and retrieval device to achieve the fully automatic loading and unloading effect of the drum washing machine cover plate, but the moving device 42 can also control the distance between the two sliding plates 41, thus adapting to hot stamping processing of drum washing machine cover plates of different diameters.

[0029] like Figure 4 As shown, the conveyor device 43 includes a pair of toothed pulleys 431 that rotate vertically on a sliding plate 41, a synchronous belt 432 sleeved on the toothed pulleys 431, a support plate 433 vertically fixed to the top of the sliding plate 41 and located in the middle of the synchronous belt 432, and a servo motor 434 that drives one of the toothed pulleys 431 to rotate. The two toothed pulleys 431 are located at both ends of the support plate 433, and the servo motor 434 is fixedly installed at the bottom of the sliding plate 41. The lower end of the toothed pulley 431 rotates through the sliding plate 41 and connects to the output end of the servo motor 434. The two sides of the support plate 433 are in parallel contact with the inner side of the synchronous belt 432. By adopting the above technical solution, not only can the drum washing machine cover plate be conveyed on the two sliding plates 41, but the synchronous belt 432, in conjunction with the support plate 433, can also clamp and position the drum washing machine cover plate to ensure that the drum washing machine cover plate is accurately conveyed to the lower clamping plate 36.

[0030] The working principle of this embodiment: When the device starts working, the servo motor 65 first drives the rotating shaft 61 and the two sprockets 62 on the rotating shaft 61 to rotate. At the same time, the chain 63 meshes with the two sprockets 62. Under the rotation of the two sprockets 62, each pair of supply plates 64 containing the drum washing machine cover is lifted. The supply plate 64 at the highest position and the drum washing machine cover on it will be lifted above the two sliding plates 41 (at this time, the distance between the two sliding plates 41 is greater than the diameter of the drum washing machine cover). Next, servo motor 7 423 will drive rotating shaft 3 422, causing rotating shaft 3 422 to drive sprocket 3 424 in the two U-shaped plates 421 to rotate. At the same time, chain 3 425 meshing with sprocket 3 424 will drive slider 1 426 and slider 2 427 to slide relative to the top of U-shaped plate 421 as the two sprockets 3 424 rotate. Since slider 1 426 and slider 2 427 on U-shaped plate 421 are respectively fixedly connected to the parts of chain 3 425 that move up and down in opposite directions, slider 1 426 and slider 2 427 will drive the sliding plates 41 they are connected to to move closer to each other in opposite directions until the spacing of the synchronous belt 432 on the two sliding plates 41 is the same as the diameter of the round cover of the drum washing machine. Then, the aforementioned servo motor 65 works again, and through the sprocket 62 and chain 63, it lowers each pair of supply plates 64 and the drum washing machine cover plate to a certain height. The supply plate 64 at the highest position, after descending below the two sliding plates 41, will be blocked by the two sliding plates 41 and stay between the two synchronous belts 432. In this way, the drum washing machine cover plate is supplied to the automatic loading and unloading mechanism 4. Subsequently, the servo motors 434 in the two conveyor belts 43 synchronously drive the toothed pulleys 431 to rotate, causing the two toothed pulleys 431 to drive the synchronous belts 432 above the two sliding plates 41 to move. The drum washing machine cover plate, which was previously sandwiched between the two synchronous belts 432, will move relative to the two sliding plates 41 under the movement of the two synchronous belts 432, and move from one end of the two sliding plates 41 to the upper part of the lower clamping plate 36 in the middle. Since the two sides of the lower clamping plate 36 previously extended into the notches 411 on one side of the two sliding plates 41, and the upper end surface of the lower clamping plate 36 is flush with the top of the sliding plates 41, after the drum washing machine cover plate and the lower clamping plate 36 are aligned, the drum washing machine cover plate will naturally fall on the lower clamping plate 36, thereby realizing the automatic feeding of the drum washing machine cover plate. Subsequently, the hydraulic telescopic cylinder 32 inside the casing 31 extends its piston rod, raising the lifting platform 33 and the rotating shaft 34. Simultaneously, the lower clamping plate 36 at the upper end of the rotating shaft 34 rises to lift the drum washing machine's round cover until the lower clamping plate 36 and the upper clamping plate 38 clamp and fix the drum washing machine's round cover at a certain height above the casing 31. At the same time, the screw lifting device 23 and the screw moving device 25 in the automatic hot stamping mechanism 2 control the lifting frame 22 and the sliding frame 2, respectively, during the clamping and fixing process of the drum washing machine's round cover. 4. Move the hot stamping roller 26 on the base 21 in both the height and horizontal directions until it contacts the outer contour surface of the round cover of the drum washing machine. Since the electroplated aluminum film pulled out from the electroplated aluminum film roll on the unwinding roller 27 has passed through the hot stamping roller 26 and the tensioning rollers 241 on both sides, and the end of the electroplated aluminum film is fixedly connected to the take-up roller 28, the electroplated aluminum film will be sandwiched between the two after the hot stamping roller 26 contacts the outer contour surface of the round cover of the drum washing machine. This completes the preparation work for hot stamping of the round cover of the drum washing machine. Finally, rotating device 29 and rotating device 35 drive the hot stamping roller 26, the take-up roller 28 and the rotating shaft 34 to rotate, so that the electroplated aluminum film is continuously pulled out from the electroplated aluminum film roll on the unwinding roller 27 and contacts the outer contour of the drum washing machine cover in sequence. At the same time, under the pressure between the hot stamping roller 26 and the drum washing machine cover, and under the heating condition of the hot stamping roller 26, the aluminum layer on the electroplated aluminum film will be evenly transferred to the outer contour surface of the drum washing machine cover, thereby achieving the effect of uniformly hot stamping aluminum layer on the outer contour surface of the drum washing machine cover.

[0031] After the hot stamping of the drum washing machine cover plate is completed, the hydraulic telescopic cylinder 32 automatically retracts its piston rod, causing the lower clamping plate 36 to descend to its initial height. The finished drum washing machine cover plate then returns to the two synchronous belts 432. Next, the servo motor 434 restarts, causing the two synchronous belts 432 to transport the drum washing machine cover plate above the storage plate 74. Then, the servo motor 75 drives the rotating shaft 71 and sprocket 72 to rotate, causing the chain 73 to lift all the storage plates 74. Simultaneously, the pair of storage plates 74 closest to the bottom of the drum washing machine cover plate will rise above the two sliding plates 41 during the lifting process, and as they pass through the two sliding plates 41, they will pull the drum washing machine cover plate out from the two synchronous belts 432. Afterwards, the servo motor 423... The drive shaft 3 422 and sprocket 3 424 rotate, causing chain 3 425 to drive two sliding plates 41 to slide away from each other via slider 1 426 and slider 2 427, until the distance between the two sliding plates 41 is greater than the diameter of the drum washing machine cover. Finally, servo motor 2 75 drives the drive shaft 2 71 and sprocket 2 72 to rotate in the opposite direction, causing the pair of storage plates 74 and the drum washing machine cover to descend below the two sliding plates 41. At the same time, the pair of storage plates 74 on the side of chain 2 73 away from the machine housing 31 will go around from above sprocket 2 72 to the side of the machine housing 31 and chain 2 73 that are close to each other, and continue to descend between the drum washing machine cover and the sliding plates 41. In this way, the processed drum washing machine cover is stored sequentially on each pair of storage plates 74 on chain 2 73.
