Description

Technical Field

[0001] The utility model belongs to the field of acrylic plate processing, and particularly relates to a polishing device for acrylic plate processing. Background Art

[0002] An acrylic sheet polishing device is a device specifically designed for surface treatment of acrylic materials. Acrylic (also known as PMMA or plexiglass) is a transparent plastic widely used in advertising, lighting, furniture, and other fields. The main function of a polishing device is to polish the edges and surfaces of acrylic sheets to improve their appearance, remove burrs, and enhance smoothness and transparency.

[0003] Traditionally, acrylic sheet grinding is done manually, often by pushing the sheet forward to contact the grinding wheel. Larger acrylic sheets require two operators to work together: one controls the grinding wheel, while the other pushes the sheet forward. This method is affected by factors such as the operator's pushing force, speed, and stability. The advancement distance of the sheet is not precise enough during batch grinding, and the sheet often requires reciprocating grinding, resulting in poor grinding consistency. Manually pushing the acrylic sheet requires considerable physical effort and energy, especially in mass production. Therefore, a grinding device for acrylic sheet processing is proposed to address these issues. Utility Model Content

[0009] A connecting plate is installed on the side of the connecting slider, and a grinding seat is installed on the side of the connecting plate.

[0010] As a further improvement of the present invention, the acrylic plate moving assembly also includes two linear guide rails arranged parallel to the polishing platform, and two linear sliders are slidingly provided on the two linear guide rails; the four linear sliders are arranged in a rectangular distribution and their tops are connected to the bottom of the acrylic plate supporting platform.

[0011] As a further improvement of the present invention, a reciprocating motor is installed on the side of one of the bearing seats, and the output end of the reciprocating motor extends to be connected to one end of the threaded screw.

[0012] As a further improvement of the present invention, a mounting seat is installed on the top of the acrylic plate supporting platform. The mounting seat is arranged in an inverted U shape and a guide rod cylinder is installed on the top. The output end of the guide rod cylinder extends vertically and passes through the top of the mounting seat to be connected to a lower pressure plate.

[0013] As a further improvement of the present invention, the grinding assembly further includes a reciprocating rotating motor arranged on the top of the vertical frame, and the output end of the reciprocating rotating motor passes through the vertical frame and is connected to the top end of the threaded screw.

[0030] A connecting plate 36 is installed on the side of the connecting slider 35 , and a grinding seat 37 is installed on the side of the connecting plate 36 .

[0031] In this embodiment, compared with traditional manual propulsion, the polishing device of the present application can limit acrylic plates of different sizes and thicknesses through the acrylic plate moving component 2, and drive it to move back and forth in a straight line, thereby ensuring the accurate positioning of the acrylic plate during the polishing process to improve the uniformity and consistency of the polishing.

[0032] Furthermore, preferably, compared with traditional grinding operations, the grinding device of the present application can achieve precise control of the grinding height to adapt to workpieces of different thicknesses and shapes; at the same time, through precise height adjustment, it can ensure optimal contact between the grinding seat 37 and the acrylic plate, thereby improving the grinding quality and consistency and reducing surface defects.

At this time, the screw nut 23 engaged with the outside of the threaded screw 22 can drive the nut slider 24 and the acrylic plate support platform 25 to achieve reciprocating linear operation.

[0037] Furthermore, the power supply connection method of the reciprocating motor 26 is the existing technology, and the control circuit can be implemented by simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.
