Description

Technical Field

[0001] This utility model relates to the technical field of quartz stone polishing devices, and in particular to a dust cover for quartz stone polishing. Background Technology

[0002] When processing quartz stone, grinding equipment is usually used to grind, cut and polish it. During the above processing, a large amount of fine dust with strong diffusion will be generated, which not only pollutes the working environment and affects the visibility of the processing, but also affects the health of the operators.

[0003] To address the aforementioned issues, Chinese utility model patent CN212240517U discloses a "dust hood for quartz stone polishing," comprising a housing with an inner cavity divided into an installation cavity on the left and a dust removal cavity on the right. A carrying rod is fixed to the housing, an air duct is fixed to the right end of the housing, and a hollow dust suction hood is provided at the left end of the housing. The inner wall of the dust suction hood has a dust suction hole communicating with the inner cavity of the dust suction hood. This utility model reduces dust diffusion at the source by removing dust during polishing and centrally treating the dust, thereby improving the working environment to a certain extent.

[0004] However, in actual use, the suction holes of this technology are prone to dust accumulation due to long-term use or blockage by large debris generated during processing, which greatly reduces the smoothness of the suction channel. This problem will directly weaken the suction power of the device and ultimately seriously affect the overall dust removal efficiency, making it difficult to meet the continuous and efficient dust removal needs of quartz stone processing. Utility Model Content

[0005] This invention provides a dust cover for quartz stone polishing that can effectively prevent dust blockage and maintain long-lasting and efficient dust removal capabilities, thereby solving the defects in the existing technology.

[0006] The technical solution is as follows: A dust cover for grinding quartz stone includes: a grinding machine, a drive shaft fixedly connected to the grinding machine, a grinding block fixedly connected to the drive shaft, and a cover fixedly connected to the grinding machine. The grinding block is assembled and fixed to the drive shaft using mounting parts. The cover covers the outside of the grinding block and has dust suction holes on its inner wall and a cavity inside, which communicates with the dust suction mechanism built into the grinding machine. The structure also includes: a mounting rail, with a mounting rail fixedly connected to the inner wall of the cover; and a connecting seat. The mounting track is equipped with sliding connecting seats, which will circulate along the track. Their length is greater than the distribution width of the dust collection holes, so that the circulating movement of the connecting seats can cover all the dust collection holes. The number of sets of connecting seats corresponds one-to-one with the number of mounting parts, and the connecting seats and the corresponding mounting parts make contact and fit. Brush bristles are fixedly connected to each set of connecting seats. The brush bristles are in direct contact with the dust collection holes on the inner wall of the cover. They use the relative displacement formed between the connecting seats and the dust collection holes when the connecting seats slide along the mounting track to clean the dust or debris blocking the dust collection holes.

[0007] Optionally, the structure further includes: a mounting cavity, which is fixedly connected to the connecting seat; a pressure block, which is slidably connected to the mounting cavity; and a return spring, which is fixedly connected between the mounting cavity and the pressure block, and the elastic force of the return spring makes the pressure block and the grinding block in stable contact.

[0008] Optionally, the structure further includes a friction layer, wherein a friction layer is fixedly connected to the contact surface of the pressing block and the grinding block to increase the friction of the contact surface of the pressing block.

[0009] Optionally, the structure further includes a cover plate, which is slidably connected to the mounting rail and is fixed to the connecting seat and moves synchronously therewith, so as to provide dynamic protection for the mounting rail.

[0010] Optionally, the structure further includes a protective layer, which is fixedly connected to the contact surface between the connector and the mounting component to soften the force when they come into contact.

[0011] Optionally, the structure further includes a guide ramp, which is provided on the connecting seat to guide dust to the outside of the connecting seat.

[0012] The beneficial effects of this utility model are: This utility model uses a connecting seat and brush bristles to achieve full-range coverage cleaning of all suction holes, effectively removing dust or debris clogging the suction holes, ensuring unobstructed suction holes, and maintaining the long-lasting and efficient dust removal capability of this utility model; at the same time, the connecting seat is moved by the contact transmission between the mounting part and the connecting seat, without the need for additional power to drive the cleaning structure, simplifying the overall structural design of this utility model and saving energy consumption, and can be cleaned simultaneously with the grinding operation without generating operation time.

[0013] In this invention, the pressure block maintains stable contact with the grinding block by means of the elastic force of the return spring. As the grinding block pushes the connecting seat through the mounting component, the contact friction between the pressure block and the grinding block enhances the transmission stability and prevents the connecting seat from sliding or getting stuck. Furthermore, the above structure does not affect the disassembly and replacement of the grinding block, ensuring the convenience of grinding block replacement. Attached Figure Description

Detailed Implementation

[0019] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0020] Example: A dust cover for polishing quartz stone, such as Figures 1-4As shown, the device includes: a polishing machine 1; a drive shaft 101, which is fixedly mounted on the polishing machine 1 and driven to rotate; a polishing block 102, which is assembled and fixedly mounted on the drive shaft 101 using mounting parts 103, rotating synchronously with the drive shaft 101 to polish the quartz stone; the mounting parts 103 are specifically fixing bolts, allowing for easy replacement of the polishing block 102 according to actual usage needs, such as wear of the polishing block 102 or changes in polishing precision requirements; and a cover 104, which is fixedly mounted on the polishing machine 1 and covers the outside of the polishing block 102, providing protection and dust collection. The cover has suction holes on its inner wall and an internal cavity that connects to the built-in suction mechanism of the polishing machine 1. When the suction mechanism is activated, dust is drawn through the suction... The structure also includes: a mounting track 2, which is fixedly installed on the inner wall of the cover 104; a connecting seat 3, which is slidably installed on the mounting track 2 and will circulate along the mounting track 2. Its length is greater than the distribution width of the dust suction holes, so that the circulating movement of the connecting seat 3 can cover all the dust suction holes. There are two sets of connecting seats 3, which correspond one-to-one with the number of mounting parts 103 of the grinding block 102, and the connecting seat 3 and the corresponding mounting part 103 make contact and fit; and bristles 4, which are fixedly installed on each set of connecting seats 3. The bristles 4 are in direct contact with the dust suction holes on the inner wall of the cover 104. They use the relative displacement formed between the connecting seat 3 and the dust suction holes when it slides along the mounting track 2 to clean the dust or debris blocked in the dust suction holes.

[0021] When using this structure to polish quartz stone, start the polisher 1. The polishing block 102 will rotate via the drive shaft 101 to perform the polishing operation. At the same time, the dust collection mechanism built into the polisher 1 will absorb the dust generated during polishing through the cavity of the cover 104 and the dust collection holes. While the polishing block 102 is rotating, its mounting part 103 will rotate synchronously. When the mounting part 103 contacts and engages with the connecting seat 3, it will push the connecting seat 3 to move cyclically along the mounting track 2, so that the bristles 4 on it will simultaneously clean all the dust collection holes in a full range, ensuring that the dust collection holes are unobstructed and maintaining the long-lasting and efficient dust removal capability of this structure.

[0022] like Figure 2 As shown, this structure also includes: a cover plate 9, which is slidably installed on the mounting rail 2 and is fixed to the connecting seat 3 and moves synchronously therewith, so as to form dynamic protection for the mounting rail 2 and prevent dust from entering the mounting rail 2 and causing the connecting seat 3 to be obstructed; a protective layer 10, which is fixedly installed on the contact surface between the connecting seat 3 and the mounting part 103, to soften the force when the two are in contact, reduce component wear, and improve structural safety and service life; and a guide slope 11, which is equipped on the connecting seat 3 to guide dust to the outside of the connecting seat 3, to prevent dust from accumulating on the surface of the connecting seat 3, thereby reducing the difficulty of cleaning.

[0023] like Figure 2 and Figure 4 As shown, this structure also includes: a mounting cavity 5, which is fixedly mounted on the connecting seat 3; a pressure block 6, which is slidably mounted on the mounting cavity 5; a return spring 7, which is fixedly mounted between the mounting cavity 5 and the pressure block 6, and whose elastic force can keep the pressure block 6 and the grinding block 102 in stable contact; and a friction layer 8, which is fixedly mounted on the contact surface between the pressure block 6 and the grinding block 102, thereby increasing the contact friction and further improving the contact stability between the pressure block 6 and the grinding block 102.

[0024] With the cooperation of the return spring 7 and the pressure block 6, the grinding block 102 can push the connecting seat 3 to rotate through the mounting part 103, and at the same time, it can form a contact friction transmission with the pressure block 6, which greatly improves the stability of the rotation transmission of the connecting seat 3; and this transmission method does not affect the disassembly and replacement of the grinding block 102, making the operation convenient.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included 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.
