Description

Technical Field

[0001] This utility model relates to the field of pad printing machine technology, and in particular to a pad printing machine adhesive removal mechanism. Background Technology

[0002] Pad printing machines are printing equipment suitable for plastics, toys, glass, metals, ceramics, electronics, IC packaging, etc. Pad printing is an indirect concave pad printing technology, which has become a major method for printing and decorating various object surfaces. During the use of pad printing machines, different patterns need to be printed, and the patterns originally left on the pad need to be removed. Usually, the staff will replace the pad. However, during the replacement process, the staff needs to spend time and effort to replace and recalibrate the pad, which will cause the printing work to be interrupted and delay the work time.

[0003] Therefore, we propose a pad printing machine adhesive removal mechanism to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pad printing machine adhesive removal mechanism to solve the technical problem in the prior art that "during the use of the pad printing machine, different patterns need to be printed, and the patterns originally left on the adhesive head need to be removed. Usually, the staff will replace the adhesive head, but in the process of replacing the adhesive head, the staff needs to spend time and effort to replace and recalibrate and adjust, which will cause the printing work to be suspended and delay the work time."

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pad printing machine adhesive removal mechanism includes a pad printing machine body and an adhesive removal component. The adhesive removal component is disposed on the pad printing machine body and includes a mounting plate, a second side plate, and a first side plate. Multiple conveying rollers are evenly spaced along the top of the mounting plate. Each conveying roller is rotatably connected to both ends of a support member. The lower end of each support member is fixedly mounted on the side wall of the mounting plate. Both ends of the mounting plate are provided with a steering roller. Both ends of the steering roller are rotatably connected to end plates. The other end of each end plate is fixedly mounted on the side wall of the mounting plate.

[0007] The upper end of the second side plate is fixedly installed on the side wall of the mounting plate. The side wall of the second side plate has a mounting hole. A central shaft is transversely inserted into the mounting hole. The central shaft is slidably connected in the mounting hole. One end of the central shaft is rotatably sleeved with a limit ring. The limit ring is fixed to the second side plate by bolts. The other end of the central shaft is fixedly connected to a second limit plate. An unwinding roller is fixedly installed on the other side of the second limit plate.

[0008] The upper end of the first side plate is fixedly installed on the side wall of the mounting plate. A gear reducer is fixedly installed on the side wall of the first side plate. A servo motor is provided at the input end of the gear reducer. The output end of the gear reducer passes through the side wall of the first side plate and is fixedly installed with a first limiting plate. A take-up roller is fixedly installed on the other side of the first limiting plate.

[0009] As a preferred embodiment of this utility model, four support rods are symmetrically and fixedly installed on the lower end of the mounting plate, and the lower ends of the four support rods are slidably connected to a support plate, which is fixedly installed on the main body of the pad printing machine.

[0010] As a preferred embodiment of this utility model, a telescopic cylinder is fixedly installed on the lower end face of the support plate, and the telescopic end of the telescopic cylinder passes through the upper end face of the support plate and is equipped with a lifting block, which is located directly below the mounting plate.

[0011] As a preferred embodiment of this utility model, a cleaning cloth is provided on the unwinding roller, one end of which is placed on the unwinding roller, and the other end of the unwinding roller is wound around the take-up roller after passing through the guide roller and the conveyor roller.

[0012] As a preferred technical solution of this utility model, the ink tray and independent printing head are also used in conjunction with the adhesive removal part.

[0013] As a preferred technical solution of this utility model, the parts used in conjunction with the cleaning parts also include a feeding robot, a sprue cutter, a shuttle clamp, and a discharging robot.

[0014] This utility model provides a pad printing machine adhesive removal mechanism, which has the following beneficial effects:

[0015] The telescopic cylinder extends upwards, lifting the mounting plate up and down via the lifting block. This allows the cleaning cloth on the upper surface of the mounting plate to press against the printing pad. Then, the servo motor starts, and through its output, it activates the gear reducer. The output of the gear reducer drives the take-up roller to rotate counterclockwise and the unwind roller to rotate clockwise. This causes the cleaning cloth to wipe the surface of the printing pad, removing the ink residue. This facilitates the replacement of the printing pad and allows for continued use. This solves the technical problem that "during the use of the pad printing machine, different patterns need to be printed, and the original patterns left on the pad need to be removed. Usually, the staff will replace the pad, but the replacement process requires time and effort to replace and recalibrate, which leads to the interruption of printing work and delays."

Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0024] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments:

[0025] refer to Figure 1-2The pad printing machine includes a feeding robot 6, a sprue 10, a pad printing host 1, an ink tray 2, a glue removal component 3, an independent printing head 9, and a rotating worktable 4 composed of rotary motors 5 and 12, a shuttle module 11, a pressing mechanism 15, an automatic lifting motor 14, and a manual lifting mechanism 13. After printing, the products are unloaded by the unloading robot 7 and placed on the assembly line for packaging. The motion control is completed by the touch screen 8.

The rotary servo motors 5 and 12 rotate, and the servo shuttle module 11 completes multi-station multi-color printing. The printing is completed by the independent printing head 9, and then the unloading robot 7 unloads the products onto the assembly line for packaging.

[0026] refer to Figure 3-5 The adhesive removal component 3 is installed on the main body 1 of the pad printing machine. The adhesive removal component 3 includes a mounting plate 308, a second side plate 311 and a first side plate 307. Multiple conveying rollers 309 are arranged at equal intervals along the mounting plate 308 above the mounting plate 308. Each conveying roller 309 is rotatably connected to a support member 310 at both ends. The lower end of each support member 310 is fixedly installed on the side wall of the mounting plate 308. Both ends of the mounting plate 308 are provided with a steering roller 306. Both ends of the steering roller 306 are rotatably connected to an end plate 301. The other end of the end plate 301 is fixedly installed on the side wall of the mounting plate 308.

[0027] The upper end of the second side plate 311 is fixedly installed on the side wall of the mounting plate 308. The side wall of the second side plate 311 has a mounting hole. A central shaft 318 is transversely inserted into the mounting hole. The central shaft 318 is slidably connected in the mounting hole. One end of the central shaft 318 is rotatably sleeved with a limit ring 319. The limit ring 319 is fixed on the second side plate 311 by bolts. The other end of the central shaft 318 is fixedly connected to a second limit plate 320. The unwinding roller 312 is fixedly installed on the other side of the second limit plate 320.

[0028] The upper side of the first side plate 307 is fixedly installed on the side wall of the mounting plate 308. A gear reducer 304 is fixedly installed on the side wall of the first side plate 307. A servo motor 305 is provided at the input end of the gear reducer 304. The output end of the gear reducer 304 passes through the side wall of the first side plate 307 and is fixedly installed on the first limiting plate 303. A take-up roller 302 is fixedly installed on the other side of the first limiting plate 303.

[0029] Among them, four support rods 313 are symmetrically fixedly installed on the lower end of the mounting plate 308, and the lower ends of the four support rods 313 are slidably connected to the support plate 314, which is fixedly installed on the main body 1 of the pad printing machine.

[0030] A telescopic cylinder 316 is fixedly installed on the lower end face of the support plate 314. The telescopic end of the telescopic cylinder 316 passes through the upper end face of the support plate 314 and is equipped with a lifting block. The lifting block is located directly below the mounting plate 308.

[0031] The unwinding roller 312 is provided with a cleaning cloth 317. One end of the cleaning cloth 317 is placed on the unwinding roller 312, and the other end of the unwinding roller 312 passes through the guide roller 306 and the conveyor roller 309 and then wraps around the take-up roller 302.

[0032] Among them, the ink tray 2 and the independent printing head 9, which are used in conjunction with the cleaning part 3, are also installed on the main body 1 of the pad printing machine.

[0033] Among them, the parts used in conjunction with the cleaning component 3 include a loading robot 6, a sprue 10, a shuttle clamp 4, and an unloading robot 7.

[0034] Specifically, when the printing head 9 finishes printing the previous pattern and needs to print the next pattern, it only needs to be controlled by the touch screen 8 to move the printing head 9 directly above the mounting plate 308. Then, the touch screen 8 controls the telescopic cylinder 316 to start, and the telescopic end of the telescopic cylinder 316 extends upward, lifting the mounting plate 308 up and down through the lifting block, so that the adhesive tape 317 on the upper surface of the mounting plate 308 presses against the printing head 9. Then, the servo motor 305 starts, and the servo motor 305 starts the gear reducer 304 through the output end. The output end of the gear reducer 304 drives the take-up roller 302 to rotate counterclockwise. The unwinding roller 312 rotates clockwise, causing the cleaning cloth 317 to wipe the surface of the printing pad 9, removing the ink from the printing pad 9. This makes it easier to replace the printing pad 9 for continued use. At the same time, the cleaning cloth 317 is wound up and recycled by the rewinding roller 302. This solves the technical problem that "during the use of the pad printing machine, different patterns need to be printed, and the patterns left on the pad need to be removed. Usually, the staff will replace the pad. However, during the replacement process, the staff needs to spend time and effort to replace and readjust the pad, which will cause the printing work to be interrupted and delay the work time."

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
