Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and in particular to a transfer device for transfer stickers. Background Technology

[0002] Transfer stickers are a type of sticker used to decorate the surface of clothing or models. The main body is a transparent plastic sheet with a pattern, and the surface is covered with a protective paper layer to prevent the sticker from being damaged. When using it, the patterned side of the sticker needs to be attached to the surface of the model or clothing, and the pattern is completely transferred to the target position by a transfer device.

[0003] Traditional equipment for producing transfer stickers includes a base and a rotating transfer plate. A perforated mold plate is located in the center of the transfer plate, and a printing plate is movably mounted on it. Blank transfer stickers are placed on the base, and the movement of the transfer plate causes the perforated mold plate to press down on the blank transfer stickers. The printing plate is equipped with pipes for the outflow of printing liquid. The printing liquid is transferred onto the transfer stickers through the gaps in the perforated mold plate and the movement of the printing plate. The overall transfer efficiency is convenient and fast.

[0004] However, after printing, some printing liquid remains on the die plate. If too much is left, it is easy to overflow and is inconvenient to recycle. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a transfer device for transfer stickers.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A transfer device for transfer stickers includes a base and a transfer plate rotatably mounted thereon. A mold plate is disposed in the middle of the transfer plate, and a printing plate is movably disposed on the mold plate. Receiving grooves are formed at opposite ends within the mold plate. Driving rods are arranged opposite each other within the receiving grooves. The two sets of driving rods are rotatably connected to the receiving grooves at their closest points via rotating rods. A scraper is rotatably disposed at the other end of each driving rod. A guide groove is formed on the inner wall of the receiving groove along the length of the mold plate. One end of the plate is slidably connected to the guide groove via a guide rod. Two sets of opposing rotating rods are provided with expansion plates arranged vertically and horizontally. Each of the two sets of expansion plates has a rack on its closest side. A sliding block is provided inside the storage groove. The sliding block is located between the two sets of expansion plates and is provided with a gear that meshes with the rack. A gear is sleeved on the rotating rod. A rack is provided on the outer wall of the sliding block that meshes with the gear. Several sets of flow pipes are provided inside the mold plate. A main pipe is provided outside the mold plate and communicates with the flow pipes.

[0007] Preferably, a motor is mounted on the sliding block, and the gear is mounted on the output shaft of the motor.

[0008] Preferably, a cylinder is provided on the outside of the mold plate, and the top end of the piston rod of the cylinder passes through the storage groove and is connected to the sliding block.

[0009] Preferably, a flexible pad is provided on the lower side of the scraper.

[0024] like Figures 1 to 6As shown, a transfer device for transfer stickers includes a base 1 and a transfer plate 2 that rotates on it. The transfer plate 2 is hollow in the middle, and a mold plate 3 is disposed in the middle. In this embodiment, ball screws (not shown in the figure) are disposed on the left and right sides of the transfer plate 2 along its width direction. The ball screws are driven by a motor (not shown in the figure). Pneumatic actuators (not shown in the figure) are slidably disposed on the ball screws. The piston rods of the two sets of pneumatic actuators are respectively connected to the left and right ends of the printing plate 4. The purpose is to enable the printing plate 4 to move up and down through the movement of the pneumatic actuators. At the same time, the ball screws can indirectly drive the printing plate 4 to move back and forth on the upper side of the mold plate 3. A pipe for the outflow of printing liquid (not shown in the figure) is provided on the printing plate 4. The above structures are all technical components conventionally used by those skilled in the art.

[0025] The mold plate 3 consists of a frame and a hollow plate embedded therein. Storage grooves 5 are formed on the front and back sides of the inner wall of the frame. Driving rods 6 are arranged symmetrically in the storage grooves 5. The two sets of driving rods 6 are rotatably connected to the inner wall of the storage grooves 5 via rotating rods 7 at their closest points. A scraper 8 is rotatably mounted on the other end of the driving rods 6. A guide groove is formed along the length of the mold plate 3 on the inner wall of the storage grooves 5. A guide rod 9 is slidably connected to the guide groove at one end of the scraper 8. The purpose of this is to limit the range of motion of the scraper 8 when the driving rods 6 drive the scraper 8, through the cooperation between the guide rod 9 and the guide groove. Extension plates 10 are arranged alternately on the two sets of rotating rods, as shown in the details. Figures 4 to 6 As shown, rack 11 is provided on the side of each of the two sets of expansion plates 10 that are close to each other. A sliding block 12 is provided inside the storage groove 5 between the two sets of expansion plates 10. A gear 13 that meshes with rack 11 is provided on the sliding block 12. The upper and lower ends of gear 13 mesh with the two sets of rack 11 respectively. A gear 24 is sleeved on the outer wall of the rotating rod 7. A rack 25 that meshes with gear 24 is provided on the outer wall of the sliding block 12. An electromagnetic suction block 21 is embedded on the side of the expansion plate 10 facing the rotating rod 7. A magnetic suction block 22 that magnetically engages with the electromagnetic suction block 21 is embedded on the upper side of the gear. The purpose is to fix the position of gear 24 when it disengages from rack 25, so as to avoid misalignment with rack 25 during the return movement.

[0026] Several sets of flow pipes 16 are provided on the upper side inside the mold plate 3. A main pipe 17 is provided on the outside of the mold plate 3 and communicates with the flow pipes 16. A flexible pad 19 is provided on the lower side of the scraper 8. A motor (not shown in the attached figure) is provided on the sliding block 12. A gear 13 is sleeved on the output shaft of the motor and is driven by the motor. A cylinder 18 is provided on the outside of the mold plate 3. The top of the piston rod of the cylinder 18 passes into the storage groove 5 and is connected to the sliding block 12. The sliding block 12 is moved horizontally by the extension and retraction of the cylinder 18. A storage box 20 is provided on the outer wall of the base 1. The opening of the storage box 20 is located directly below the main pipe 17 and is used to collect the printing liquid flowing out of the main pipe 17. In this embodiment, an electric shut-off valve (not shown in the attached figure) is provided on the main pipe 17. Its purpose is to prevent the printing liquid on the mold plate 3 from flowing out when it is not necessary.

[0027] When performing the transfer of the transfer sticker normally, place a blank transfer sticker on base 1, such as... Figure 1 As shown, the scrapers 8 are all located in the receiving groove 5, the cylinder 18 is in the retracted state, the main pipe 17 is in the closed state, the printing plate 4 moves parallel to the mold plate 3 through the ball screw, and moves up and down through the pneumatic actuator. After the transfer is completed, the printing plate 4 moves up without contacting the upper side of the mold plate 3.

[0028] At this time, the control cylinder 18 extends, and the cylinder 18 moves the rack 15 through the sliding block 12. The gear 14 on the rotating rod 7 meshes with the rack 15, driving the driving rod 6 to rotate around the central axis of the rotating rod 7 by a certain angle, and pulling one end of the scraper 8 out of the receiving groove 5. The other end of the scraper 8 is limited by the guide rod 9 and slides in the guide groove. Figures 3 to 6 As shown, one end of the scraper 8 is located directly above the mold plate 3. At this time, the electromagnetic suction block 21 and the magnetic suction block 22 on the gear 14 magnetically attract each other, limiting the position of the rotating rod 7 and further fixing the position of the driving rod 6. The motor starts to rotate forward and is driven indirectly by the gear 13 meshing with the rack 11 on the upper and lower extension plates 10. The driving plate drives the scraper 8 to move on the mold plate 3. The flexible pad 19 under the scraper 8 adheres to the mold plate 3. During the movement, the printing liquid remaining on the mold plate 3 will be cleaned to the edge and flow out through the flow pipe 16. At this time, the electric shut-off valve is opened, and the printing liquid flows out of the main pipe 17 into the storage box 20, completing the collection of the residual printing liquid on the mold plate 3.

[0029] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
