[0015] The technical solution of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0016] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0017] Reference Figure 1 and Figure 2 The utility model proposes a dust removal mechanism for remote control buttons, including a dust removal bracket 3, a lifting bracket 32 ​​that can move up and down is provided on the dust removal bracket 3, a dust sticking roller 31 is installed at the lower part of the lifting bracket 32, and a limiting structure that can limit the maximum downward movement of the lifting bracket 32 ​​relative to the dust removal bracket 3 is provided between the lifting bracket 32 ​​and the dust removal bracket 3, and the lifting bracket 32 ​​is connected to an elastic device that can apply a downward elastic force to the lifting bracket 32.

[0018] This dust removal mechanism can be used on screen printing machines. When the turntable rotates, a mold with remote control buttons mounted on it moves from the loading station to the screen printing station. The screen printing mechanism at this station then prints numbers or symbols on the workpiece. During this process, the mold comes into contact with a sticky roller, which automatically removes dust from the workpiece.

[0019] In one embodiment, the lifting frame 32 includes a crossbar 322 and a first guide post 323 fixed to the crossbar 322. The dust removal bracket 3 includes a base plate 35 located above the crossbar 322. The base plate 35 is provided with a guide hole that slidably engages with the first guide post 323. The limiting structure includes a limit block 3231 provided on the first guide post 323, the lower surface of the limit block 3231 abutting the upper surface of the base plate 35. The elastic device includes a compression spring 34 sleeved on the first guide post 323, the upper end of the compression spring 34 abutting the base plate 35, and the lower end of the compression spring 34 abutting the crossbar 322. This design makes the dust sticking roller 31 on the lifting frame 32 elastically retractable, and the lowest point of the dust sticking roller 31 can be set slightly lower than the upper surface of the workpiece on the mold 22, so that the workpiece can be pressed by the dust sticking roller 31 when passing through it, thereby improving the dust removal effect. In order to enable the sticky roller 31 to smoothly roll over the workpiece on the mold, a guiding slope may be provided at the head end of the mold.

[0020] Furthermore, two hinged seats 33 are provided on the lifting frame 32, one on the left and one on the right. At least one of the hinged seats 33 is detachably connected to the lifting frame 32. The sticky roller 31 includes a main shaft 311 and a cylindrical consumable material 312 mounted on the main shaft 311. Both hinged seats 33 have sockets, and both ends of the main shaft 311 can be rotatably inserted into the corresponding sockets, so that the two ends of the main shaft 311 are rotatably connected to the two hinged seats 33. Specifically, two mounting seats 321 are provided on the lifting frame 32, one on the left and one on the right. The left mounting seat 321 has a slot 3211 with a leftward opening, and the right mounting seat 321 has a slot 3211 with a rightward opening. The hinged seats 33 have insertion arms 331, each of which is mounted in a corresponding slot 3211 and threadedly connected to the corresponding mounting seat 321. This design allows the cylindrical consumable material 312 to be removed and replaced after use. The cylindrical consumable 312 can be a specially made sticky device or can be purchased from the market. For example, a replacement roll of lint remover commonly found on the market can be used. The surface of the replacement roll of paper has many layers of sticky paper adhered to it. After using it for a period of time, the surface layer of sticky paper can be torn off, and the inner layer of sticky paper can be used to remove dust from the surface of the workpiece.

[0021] In one embodiment, the dust removal bracket 3 includes a bottom plate 36, a top plate 37, a second guide post 38 fixed between the bottom plate 36 and the top plate 37, a lifting seat 39 that slidably engages with the second guide post 38, and a height locking device capable of locking the lifting seat 39. The aforementioned base plate 35 is mounted on the lifting seat 39. This design allows the height of the sticky roller 31 to be adjusted. When the diameter of the cylindrical consumable 312 of the sticky roller 31 is significantly reduced, or when the height of the mold 22 changes due to a change in product, the height locking device can be unlocked, and the lifting seat 39 can then be moved up and down to adjust the sticky roller 31 to the appropriate height. Finally, the lifting seat 39 can be locked using the height locking device.

[0022] In one embodiment, the height locking device includes a set screw 51 threadedly connected to the lifting base 39. The tip of the set screw 51 can abut against the second guide post 38 to lock the lifting base 39. The head of the set screw 51 is connected to a handle 511. The lifting base 39 can be unlocked by loosening the set screw 51 using the handle 511, and locked by tightening the set screw 51 using the handle 511.

[0023] Furthermore, a handwheel 52 is rotatably mounted on the top plate 37. A lifting transmission mechanism is provided between the handwheel 52 and the lifting base 39, capable of driving the lifting base 39 up and down when the handwheel 52 is rotated. Preferably, the transmission mechanism includes a screw 53 rotatably mounted between the top plate 37 and the bottom plate 36. A nut 54 is provided on the lifting base 39, engaging with the screw 53. The upper end of the screw 53 protrudes from the upper surface of the top plate 37, and the handwheel 52 is fixed to the upper end of the screw 53. With this design, after the lifting base 39 is unlocked, the height of the sticky roller 31 can be precisely adjusted by rotating the handwheel 52.

[0024] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
