Description

Technical Field

[0001] This application relates to the field of pad printing equipment technology, and more particularly to a shaft expansion mechanism and a glue removal process module including the shaft expansion mechanism. Background Technology

[0002] As a commonly used printing device, pad printing machines utilize a glue cleaning system. A drive wheel rotates a belt on a driven wheel, causing the moving stamp head to contact the belt. The belt removes the glue from the moving stamp head, thus cleaning it. During the cleaning process, the glue-laden belt is wound onto the drive wheel, while a new belt is simultaneously released from the driven wheel, automatically replacing the belt.

[0003] However, existing pad printing machines have some problems with the use of tape. When all the tape on the driven roller is used up and wound onto the drive roller, the waste tape loops wound on the drive roller need to be removed. However, the waste tape loops are wound tightly around the drive roller, making them difficult to remove. Currently, the waste tape loops are usually removed by scraping or pulling with a knife. This traditional method is not only inefficient and increases manual operation time and labor intensity, but also poses certain safety hazards, easily leading to operator injury. Furthermore, scraping off the waste tape loops requires cutting the tape wound on the drive roller, which may cause accidental damage to components such as the drive shaft of the pad printing machine, affecting the normal service life and operational stability of the equipment, and consequently impacting the overall efficiency and quality of the pad printing work. Utility Model Content

[0004] The technical problem this utility model aims to solve is the inconvenience and high risk associated with the operation of existing pad printing machine glue cleaning devices when removing waste tape rings.

[0005] To address this issue, this invention provides an expansion shaft mechanism. By adjusting the radial distance between the top plate and the tensioning shaft, the overall outer diameter of the expansion shaft mechanism can be adjusted. Waste tape is wound around the expansion shaft mechanism, and the top plate supports the inner ring of the waste tape ring. When removing the waste tape ring, the overall outer diameter of the expansion shaft mechanism is contracted by adjusting the radial distance between the top plate and the tensioning shaft, causing the tape ring to separate from the top plate. The waste tape ring can then be easily removed and discarded, improving the efficiency of waste tape replacement, reducing the difficulty and risk of manual operation, and effectively avoiding potential damage to the equipment caused by the use of cutting tools. This improves the overall performance and reliability of the pad printing machine, ensuring the continuity and stability of pad printing operations.

[0006] An expansion shaft mechanism according to an embodiment of the present utility model includes:

[0007] Tensioner shaft, and;

[0008] A sleeve, which is sleeved on the tensioning shaft and moves axially along the tensioning shaft;

[0009] The top plate is provided in a ring around the axis of the tensioning shaft. Each top plate is connected to the sleeve by a connecting rod assembly. When the sleeve moves axially along the tensioning shaft, the connecting rod assembly drives the top plate to move radially along the tensioning shaft.

[0010] According to one embodiment of the present invention, a base plate is provided at the end of the tensioning shaft, and a spring is provided between the base plate and the sleeve.

[0011] According to one embodiment of the present invention, the tensioning shaft is provided with a thread, and a handwheel is threadedly connected to the tensioning shaft. The handwheel is located on the side of the sleeve away from the base plate, and the handwheel is used to control the sleeve to move axially along the tensioning shaft.

[0012] According to one embodiment of the present invention, the linkage assembly includes:

[0013] A push rod, one end of which is hinged to the sleeve and the other end of which is hinged to the top plate;

[0018] A first push rod, one end of which is hinged to the sleeve and the other end of which is hinged to the top plate;

[0019] The second push rod has one end hinged to the bottom plate and the other end hinged to the top plate. The second push rod and the first push rod are arranged crosswise and hinged to each other.

[0020] Wherein, the end of the first push rod or the second push rod that is hinged to the top plate slides in cooperation with the top plate along the axial direction of the sleeve.

[0021] According to one embodiment of the present invention, a sliding opening is provided on the top plate along the axial direction of the sleeve, and the hinge shaft between the first push rod or the second push rod and the top plate slides in cooperation with the sliding opening along the axial direction of the sleeve.

[0022] According to an embodiment of the present invention, a tape cleaning process module is also provided. The tape is simultaneously unwound and wound up via an unwinding shaft and a winding shaft. An expansion shaft mechanism is provided on the winding shaft. When winding up the waste tape, the waste tape is wound around the expansion shaft mechanism. Thus, when removing the waste tape ring, it is only necessary to shrink the overall outer diameter of the expansion shaft mechanism to easily separate the waste tape ring from the expansion shaft mechanism, thereby improving the efficiency of replacing waste tape.

[0023] A glue removal process module according to an embodiment of the present utility model includes:

[0024] Mounting base, and

[0025] An unwinding roller, which is rotatably mounted on the mounting base;

The take-up roller is provided with the tensioning shaft mechanism as described above, and the tensioning shaft is coaxially connected to the take-up roller.

[0027] The tape has one end wound around the unwinding roller and the other end wound around the expansion shaft mechanism.

[0028] According to one embodiment of the present invention, a support plate is provided on the mounting base. The support plate is located above the take-up roller and the unwind roller, and is spaced apart from the take-up roller and the unwind roller. The support plate is located between the take-up roller and the unwind roller, and is supported below the tape located between the take-up roller and the unwind roller, and is opposite to the non-adhesive surface of the tape.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] A glue removal process module includes a worktable 1, a cleaning component 3, and a pad printing component 2. The pad printing component 2 is disposed on the worktable 1, and the cleaning component 3 is disposed on the worktable 1 and located on one side of the pad printing component 2. The glue removal process module is disposed below a movable stamp head that can move along three axes.

[0045] The pad printing assembly 2 includes a pad printing plate 21, a glue cup 23, and a drive component 24 for controlling the movement of the pad printing plate 21. A mounting bracket 22 is fixedly mounted on the worktable 1, and the glue cup 23 is fixedly mounted on the mounting bracket 22 with its bottom suspended. The mounting bracket 22 has a through-hole, and the pad printing plate 21 is located below the glue cup 23. The pad printing plate 21 moves along the X-axis through the through-hole. Multiple sliders 25 are arranged on the worktable 1 along the X-axis. A slide rail 26 is provided at the bottom of the pad printing plate 21 to slide with the sliders 25. The length of the slide rail 26 is arranged along the X-axis, and the slide rail 26 is located at the middle position of the pad printing plate 21 along the Y-axis. In this application, the driving component 24 is set as a cylinder. The output end of the cylinder is connected to one end of the pad printing plate 21 through a connecting plate 212. The output end of the cylinder and the connecting plate 212 can be connected by a floating joint to buffer and align the connecting plate 212. A baffle 213 is connected to the pad printing plate 21. The baffle 213 is located in the middle of the side of the pad printing plate 21 away from the driving component 24. Two buffer devices are also provided on the worktable 1, namely a first buffer device 27 and a second buffer device 28. The first buffer device 27 is located on the negative X-axis side of the connecting plate 212, and the second buffer device 28 is located on the positive X-axis side of the baffle 213. In this embodiment, both the first buffer device 27 and the second buffer device 28 are hydraulic buffer devices.

[0046] A stamp area 211 with a recessed pattern is provided on one side of the printing plate 21 in the positive X direction. The driving component 24 controls the movement of the printing plate 21, and the stamp area 211 moves to below the glue cup 23. At this time, the connecting plate 212 abuts against the first buffer device 27 to buffer the inertial force after the driving component 24 reaches the bottom. Glue is dispensed from the glue cup 23, and the glue fills the recessed pattern in the stamp area 211. Then, the driving component 24 controls the printing plate 21 to move in the positive X direction, and the stamp area 211 moves out from under the glue cup 23 and is exposed until the baffle 213 abuts against the second buffer device 28 to buffer the inertial force after the cylinder reaches the bottom. The printing plate 21 moves to the transfer operation position of the moving stamp head, so that the moving stamp head can transfer the glue in the stamp area 211.

[0047] The cleaning component 3 includes a mounting base 31, a take-up roller 32, and an unwind roller 33. The take-up roller 32 and the unwind roller 33 are arranged along the X-axis and are rotatably connected to the side of the mounting base 31 away from the pad printing component 2. The axial direction of the take-up roller 32 and the unwind roller 33 is set along the Y-axis. A drive device for driving the take-up roller 32 to rotate is provided on the side of the mounting base 31 near the pad printing component 2. It should be noted that the unwind roller 33 is provided with a tensioning mechanism 37. Adhesive tape is wound between the tensioning mechanism 37 and the unwind roller 33. A disposable adhesive tape roll is sleeved on the tensioning mechanism 37. The adhesive tape is unwound by the unwind roller 33 and wound onto the disposable adhesive tape roll by the take-up roller 32 and the tensioning mechanism 37. The adhesive side of the adhesive tape wound on the take-up roller 32 and the unwind roller 33 is away from the tensioning mechanism 37 and the unwind roller 33.

[0048] Specifically, the tensioning shaft mechanism 37 includes a tensioning shaft 371, a sleeve 372, a handwheel 373, a top plate 377, and a connecting rod assembly 378. A base 374 is provided at one end of the tensioning shaft 371, and the tensioning shaft 371 is coaxially connected to the take-up roller 32 via the base 374. The sleeve 372 is slidably sleeved on the tensioning shaft 371 along its axial direction. A base plate 375 is also fixedly connected to the tensioning shaft 371, located between the sleeve 372 and the base 374. A spring 376 is provided between the base plate 375 and the sleeve 372.

[0049] The handwheel 373 is sleeved on the tensioning shaft 371 and is used to push the sleeve 372 to slide along the axial direction of the tensioning shaft 371. Specifically, the tensioning shaft 371 is provided with threads, and the handwheel 373 is located on the side of the sleeve 372 away from the base plate 375. The handwheel 373 is threadedly connected to the tensioning shaft 371 and abuts against the sleeve 372. In other embodiments, the handwheel 373 and the sleeve 372 can be rotatably connected.

[0050] Multiple top plates 377 are provided along the circumference of sleeve 372. In this embodiment, three top plates 377 are provided. The top plates 377 are connected to the sleeve 372 through connecting rod assembly 378. A first mounting plate 3721 for mounting the connecting rod assembly 378 is provided on the outer wall of the sleeve 372. A second mounting plate 3771 for mounting the connecting rod assembly 378 is provided on the side of the top plate 377 facing the sleeve 372.

[0051] Specifically, each linkage assembly 378 includes a push rod 3781 group, a connecting rod 3783 group, and an auxiliary rod 3782 group. The push rod 3781 group includes two push rods 3781, the connecting rod 3783 group includes two connecting rods 3783, and the auxiliary rod 3782 group includes two auxiliary rods 3782. The two push rods 3781, the two connecting rods 3783, and the two auxiliary rods 3782 are symmetrically arranged on both sides of the corresponding first mounting plate 3721 and the second mounting plate 3771. Taking the push rod 3781, connecting rod 3783, and auxiliary rod 3782 located on the same side of a first mounting plate 3721 as an example, the auxiliary rod 3782 and the push rod 3781 are arranged parallel to each other along the axial direction of the sleeve 372. The auxiliary rod 3782 and the push rod 3781 are of equal length, so that the plane of the top plate 377 is parallel to the axial direction of the sleeve 372. The push rod 3781 is located on the side of the auxiliary rod 3782 closer to the bottom plate 375. One end of the auxiliary rod 3782 and the push rod 3781 are hinged to the first mounting plate 3721, and the other end is hinged to the second mounting plate 3771. One end of the connecting rod 3783 is hinged to the bottom plate 375, and the other end is hinged to the middle part of the push rod 3781.

[0052] A disposable tape roll is placed around the top plate 377. When the handwheel 373 is turned, the sleeve 372 can move axially along the tension shaft 371. When the sleeve 372 moves toward the bottom plate 375, the spring 376 is compressed, the distance between the sleeve 372 and the bottom plate 375 decreases, and the hinge point between the push rod 3781 and the first mounting plate 3721 moves closer to the hinge point between the connecting rod 3783 and the bottom plate 375. Thus, the connecting rod 3783 and the push rod 3781 rotate, causing the top plate 377 to move. 77 is pushed radially away from sleeve 372. The auxiliary rod 3782, push rod 3781, first mounting plate 3721, and second mounting plate 3771 form a parallelogram structure, so that the top plate 377 is parallel to the axial direction of sleeve 372 and moves stably radially along sleeve 372, changing the outer diameter of the expansion shaft mechanism 37. The top plate 377 presses against the inner wall of the disposable tape roll, so that the expansion shaft mechanism 37 can be adapted to disposable tape rolls of different diameters.

[0053] When the waste tape roll needs to be replaced, turn the handwheel 373 in the opposite direction. Under the action of the spring 376, the sleeve 372 moves away from the base plate 375. The connecting rod 3783 and the push rod 3781 rotate, pulling the top plate 377. The top plate 377 moves closer to the sleeve 372, reducing the outer diameter of the expansion shaft mechanism 37, so that the top plate 377 separates from the inner wall of the disposable tape roll, making it easier to remove and replace the tape roll.

[0054] Furthermore, a support plate 34 is provided on the mounting base 31. The support plate 34 is located between the take-up roller 32 and the unwind roller 33. The support plate 34 is located above the take-up roller 32 and the unwind roller 33 and is spaced apart from the take-up roller 32 and the unwind roller 33. The tape located between the take-up roller 32 and the unwind roller 33 is located above the support plate 34. The non-adhesive surface of the support plate 34 is opposite to the non-adhesive surface of the tape. Preferably, the top surface of the support plate 34 and the top surface of the pad printing plate 21 are located in the same horizontal plane.

[0055] A tension roller 35 and a pressure roller 36 are rotatably mounted on the support plate 34. The axial directions of the tension roller 35 and the pressure roller 36 are both along the Y-axis. In this embodiment, there are two pressure rollers 36. The tension roller 35 is located on one or both sides of the two pressure rollers 36 that are far apart from each other. In this embodiment, there is one tension roller 35, located between the unwinding roller 33 and the pressure roller 36 located near the unwinding roller 33. The tape unwound from the unwinding roller 33 first passes over the tension roller 35, then S-shaped around the tension roller 35 and the pressure roller 36, and then passes between the two pressure rollers 36 and the support plate 34, and is finally wound onto the take-up roller 32.

[0056] When the movable stamp head moves onto the support plate 34 and towards the support plate 34, the movable stamp head presses against the tape on the support plate 34. The tape removes the adhesive from the movable stamp head, thus cleaning it.

[0057] Example 2

[0058] In this embodiment, each linkage assembly 378 includes a first push rod 3784 group and a second push rod 3785 group. The first push rod 3784 group includes two first push rods 3784, which are symmetrically arranged on both sides of the second mounting plate 3771 on the corresponding top plate 377. One end of the first push rod 3784 is hinged to the sleeve 372, and the other end is hinged to the second mounting plate 3771. A sliding port 3772 is provided on the second mounting plate 3771 along the axial direction of the sleeve 372. In this embodiment, the sliding port 3772 is located on the side away from the bottom plate 375 from the hinge point between the first push rod 3784 and the second mounting plate 3771.

[0059] The second push rod 3785 group includes two second push rods 3785, which are symmetrically arranged on both sides of the second mounting plate 3771 on the corresponding top plate 377. One end of the second push rod 3785 is hinged to the bottom plate 375, and the ends of the two second push rods 3785 away from the bottom plate 375 are connected together by a hinge shaft. The hinge shaft passes through the sliding opening 3772 and slides along the length of the sliding opening 3772. The first push rod 3784 and the second push rod 3785 located on the same side of a second mounting plate 3771 are arranged crosswise and hinged together.

[0060] In other embodiments, the sliding port 3772 may also be located on the side of the hinge point between the second push rod 3785 and the second mounting plate 3771 near the bottom plate 375. One end of the second push rod 3785 is hinged to the bottom plate 375, and the other end is hinged to the second mounting plate 3771. One end of the first push rod 3784 is hinged to the sleeve 372. The ends of the two first push rods 3784 away from the sleeve 372 are connected together by a hinge shaft. The hinge shaft passes through the sliding port 3772 and slides along the length of the sliding port 3772.

[0061] It should be noted that the hinge shafts on push rod 3781, connecting rod 3783, auxiliary rod 3782, first push rod 3784, and second push rod 3785 can all adopt shoulder hinge pins 38. A retaining ring 39 is provided on the side of push rod 3781, connecting rod 3783, and auxiliary rod 3782 away from the head of the shoulder hinge pin 38. The inner ring of the retaining ring 39 is embedded in the groove provided on the outer wall of the shoulder hinge pin 38 to play a limiting role, prevent the shoulder hinge pin 38 from loosening during the up and down movement of the expansion sleeve 372, and ensure the stability of the mechanism.
