Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a dust removal device for silicone rubber keypad paper tape. Background Technology

[0002] Silicone rubber keypad paper tape, also known as silicone keypad paper tape, is a tool used to test the abrasion resistance of silicone rubber keypads. It is commonly used in RCA paper tape testing, a method for evaluating the abrasion resistance of polyurethane coatings applied to silicone rubber keypads. Because silicone rubber itself has poor abrasion resistance, a protective coating is usually sprayed onto its surface to improve its abrasion resistance. By using silicone keypad paper tape for testing, the wear and tear that the keypad surface coating might encounter during prolonged use can be simulated, thereby evaluating the coating's durability and the overall performance of the keypad.

[0003] In addition, silicone keypad tape can also be used to protect silicone keys, preventing dust, moisture, oil, and other impurities from entering the key body, while improving key sensitivity and making the feel smoother. This tape is a soft material that can be applied to the keys, providing both protection and optimization.

[0004] Silicone keypad paper tape requires dust removal during production to meet subsequent usage requirements. However, existing dust removal devices can only clean the top surface of the item. For example, utility model patent CN209613620U discloses a silicone keypad dust removal device with good performance. This device can easily brush away dust adhering to the silicone keypad and allows for easy replacement of the brush bristle fixing plate for continued use.

[0005] However, in actual use, this device can only remove dust from the upper surface of the silicone keypad paper tape, and cannot treat the lower surface of the silicone keypad paper tape, thus affecting the dust removal effect of the silicone keypad paper tape and failing to meet the usage requirements. Utility Model Content

[0006] The purpose of this invention is to provide a dust removal device for silicone rubber keypad paper tape to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dust removal device for silicone rubber keypad paper tape includes: a base on which a dust removal frame is mounted, and multiple sets of guide rods are rotatably mounted on the dust removal frame; an unwinding mechanism mounted on the dust removal frame for unwinding the silicone keypad paper tape; an adjusting mechanism mounted on the dust removal frame for adjusting the tension of the silicone keypad paper tape; a dust removal mechanism mounted on the dust removal frame for dust removal on both sides of the silicone keypad paper tape; and a winding mechanism mounted on the dust removal frame for winding up the dust-removed silicone keypad paper tape.

[0009] As a preferred embodiment, both the unwinding mechanism and the rewinding mechanism are composed of the same winding assembly. The winding assembly includes a winding disc rotatably mounted on the front side of the dust collector frame, a winding rod mounted on the front side of the winding disc, a winding roller slidably inserted on the winding rod, a winding sleeve fitted on the front side of the winding rod, and a winding bolt threaded onto the winding sleeve. The end of the winding bolt is in contact with the winding rod. A winding motor is also mounted on the rear side of the dust collector frame, and the output end of the winding motor is drivenly connected to the shaft end of the winding disc.

[0010] As a preferred embodiment, the winding rod is a quadrangular prism with a chamfer at its end. The chamfer facilitates the mounting of the winding roller onto the winding rod, and the quadrangular prism shape effectively prevents the winding roller from rotating relative to the winding rod.

[0011] As a preferred embodiment, the adjustment mechanism includes an adjustment groove on the dust collector frame, an adjustment screw rotatably mounted in the adjustment groove, an adjustment slider slidably mounted in the adjustment groove, the adjustment slider being threaded onto the adjustment screw, an adjustment motor also being mounted on the dust collector frame, the output end of the adjustment motor being drivenly connected to the shaft end of the adjustment screw, and an adjustment rod rotatably mounted on the front side of the adjustment slider.

[0012] As a preferred embodiment, the dust removal mechanism includes a pair of dust removal discs rotatably mounted on the front side of the dust removal frame. Each dust removal disc has a dust removal rod mounted on its front side. A dust removal roller is fitted onto the dust removal rod. A dust removal sleeve is also fitted onto the front side of the dust removal rod. A dust removal bolt is threaded onto the dust removal sleeve. The end of the dust removal bolt is in contact with the dust removal rod.

[0013] As a preferred embodiment, a dust removal gear is also installed on the shaft end of a pair of dust removal discs, and the dust removal gears are meshed with each other. A dust removal mounting base is also installed on the rear side of the dust removal frame, and a dust removal motor is installed on the dust removal mounting base. The output end of the dust removal motor is drivenly connected to the shaft end of any dust removal disc.

[0014] As a preferred embodiment, the dust removal rod is a quadrangular prism with a chamfer on its front side. The chamfer facilitates the fitting of the dust removal roller onto the dust removal rod, and the quadrangular prism shape effectively prevents the dust removal roller from rotating relative to the rod.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: By driving the dust removal discs to rotate via a dust removal motor, and through the cooperation of dust removal gears, the pair of dust removal discs can rotate synchronously. This allows the dust removal rollers on both sides to simultaneously remove dust from both sides of the silicone keypad paper tape, effectively improving the dust removal effect and better meeting usage requirements. This utility model has a reasonable structure and can simultaneously remove dust from both sides of the silicone keypad paper tape, improving dust removal efficiency and ensuring the dust removal effect, thus better meeting usage requirements.
