Description

Technical Field

[0001] This invention relates to the field of polishing technology, and in particular to a wood polishing apparatus and polishing method for manufacturing violins. Background Technology

[0002] The violin is widely played around the world and is the most important instrument in the string section of a modern orchestra. It occupies a very important position in instrumental music and is a pillar of the modern symphony orchestra.

[0003] In violin production, polishing is necessary to improve the appearance of the soundboard. This process typically involves using polishing equipment to grind the wood material. The wood is conveyed to the barrel-shaped polishing rollers via a conveyor belt, polished, and then discharged from the other end of the conveyor belt. The conveyor belt has limit rollers at both the inlet and outlet. During the polishing process, the polishing rollers simultaneously grind and polish the surface of the wood. With the flying debris, protective shielding devices are usually installed to prevent it from affecting the work of surrounding workers. However, the debris will still scatter on the grinding equipment after being shielded, and over time, it needs to be cleaned regularly to avoid affecting the normal operation of the grinding process. Alternatively, some machines use suction hoods to absorb the debris generated during grinding. Basically, there is one suction hood on each grinding roller. When the grinding roller rotates and grinds, the debris flies out at an angle upward, resulting in poor absorption of debris by the suction hood directly above.

[0004] Therefore, this invention proposes a wood polishing device and polishing method for manufacturing violins to solve the above-mentioned problems. Summary of the Invention

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figures 1-15A wood polishing device for manufacturing violins includes a conveyor belt device 1 and support bodies 3 arranged on both sides of the conveyor belt device 1. A control motor 4 is symmetrically arranged on the outer side of one of the support bodies 3. The control motor 4 is connected to a polishing roller 5. The polishing roller 5 polishes the wood board 2 to be processed. The wood board 2 to be processed is placed on the conveyor belt device 1. A suction hood 601 is arranged above the polishing roller 5. The suction hood 601 is located at the bottom end of the debris suction pipe 6. Support frames 602 are symmetrically fixed at both ends of the suction hood 601. The other end of the support frame 602 is fixed to the support body 3 by screws. The support frame 602 is connected to a cleaning auxiliary component and a polishing auxiliary mechanism.

[0039] When the wood board 2 to be processed reaches the position of the polishing roller 5 via the conveyor belt device 1, the surface of the wood board 2 is polished by the rotation of the polishing roller 5 driven by the control motor 4. The polishing roller 5 and the control motor 4 are set in the same number of groups, with two symmetrically arranged groups of polishing roller 5. The rotation directions of the polishing roller 5 are opposite; one polishing roller 5 rotates counterclockwise, and the other polishing roller 5 rotates clockwise. That is, according to the attached... Figure 5 It can be seen that the polishing roller 5 on the left rotates counterclockwise, and the polishing roller 5 on the right rotates clockwise. That is, when the two sets of polishing rollers 5 are rotating, the debris generated during the polishing process will splash towards the position between the two sets of polishing rollers 5. Then, through the cooperation of the debris suction pipe 6 and the suction hood 601, the debris generated during the polishing process of the wood board 2 to be processed is collected, avoiding debris splashing. The polishing auxiliary mechanism provides an auxiliary function for the collection of debris and impurities. At the same time, in order to further improve the efficiency of debris collection, this solution also sets a polishing auxiliary mechanism between the two sets of polishing rollers 5, which can further improve the recycling function of polishing debris, prevent the splashed debris from affecting the working environment, and play a positive role in improving the polishing quality of the template. Finally, the cleaning brush 704 in the cleaning auxiliary component cleans the debris and impurities adhering to the polishing rollers 5, ensuring the polishing quality of the wood board 2 to be processed by the polishing rollers 5.

[0040] To prevent excessive debris and impurities from accumulating on the surface of the polishing roller 5 during continuous polishing, this solution employs a cleaning auxiliary component to clean the surface of the polishing roller 5. This cleaning auxiliary component includes a connecting rod 701, a connecting seat 702, a mounting plate 703, and a cleaning brush 704. One end of the connecting rod 701 is fixedly connected to the connecting seat 702, and the other end is fixedly connected to the mounting plate 703. The connecting seat 702 is fixed to one of the support frames 602 by screws. The mounting plate 703 and the cleaning brush 704 are connected and fixed by bolts. The number of cleaning brushes 704 and the polishing roller 5 is the same, and the cleaning brushes 704 are in contact with the polishing roller 5. According to the attached... Figure 5 and attached Figure 6 It is known that the cleaning brush 704 is in contact with the polishing roller 5, and the cleaning brush 704 is located on the inner side of the roller surface of the polishing roller 5. That is, when the polishing roller 5 rotates, the debris and impurities cleaned by the cleaning brush 704 from the roller surface of the polishing roller 5 are prevented from splashing to the outside of the polishing roller 5, and the debris and impurities cleaned are also absorbed by the suction hood 601.

[0041] The polishing auxiliary mechanism utilizes a combination of methods. A portion of the splashed debris is directly absorbed by the suction hood 601, while the remainder is collected by the loading assembly on the transmission belt body 808. This reduces the working pressure on the suction hood 601 and provides a barrier and collection function for the splashed debris, effectively limiting its spread. The polishing auxiliary mechanism includes a support vertical plate 801, an auxiliary bearing 802, a load-bearing shaft 803, a transmission roller 804, an adjustment handle 805, a support positioning body 806, a fixing disc 807, a transmission belt body 808, and a loading assembly. The support vertical plate 801... Two sets of symmetrically arranged auxiliary bearings 802 are embedded through the top and bottom of the support vertical plate 801. A bearing shaft 803 is inserted into the auxiliary bearing 802. One end of the bearing shaft 803 at the top of the support vertical plate 801 extends outward and is fixedly fitted with an adjustment handle 805. The bearing shaft 803 is symmetrically fixed at both ends of the transmission roller 804. A support positioning body 806 is fixedly installed on one side of the top of one of the support vertical plates 801, and a fixing disc 807 is fixedly installed at the other end of the support positioning body 806. The fixing disc 807 is fixed to the inner side of one of the support frames 602 by screws. The transmission rollers 804 are symmetrically arranged in two sets and are connected to the transmission belt body 808. A loading assembly is provided on the outer wall of the transmission belt body 808. The loading assembly includes a fixing strip 901, a loading groove 902, a first positioning magnetic sheet 903, a temporary collection box 904, a material passage hole 905, a cover plate 906, a second positioning magnetic sheet 907, and auxiliary structures. The fixing strips 901 are equidistantly fixed on the outer wall of the transmission belt body 808, and the loading groove 902 is provided on the fixing strips 901. The first positioning magnetic sheet 903 is embedded and fixedly installed at the bottom end of the loading groove 902. The temporary collection box 904... One end of the temporary collection box 904 has an opening, and the other end corresponding to the opening is sealed. The sealed end of the temporary collection box 904 has material passage holes 905 at equal intervals. A threaded groove is provided at the opening end of the temporary collection box 904. The opening of the temporary collection box 904 is sealed by a cover plate 906, which is fixedly connected to the opening position of the temporary collection box 904 by screws. A second positioning magnetic sheet 907 is embedded and fixedly provided on the outside of the cover plate 906. The second positioning magnetic sheet 907 and the first positioning magnetic sheet 903 are positioned correspondingly and attract each other. An auxiliary structure is provided at the inner opening position of the material passage hole 905.

[0042] Some impurities enter directly from the material passage 905 at the end of the temporary collection box 904 and are temporarily collected there. Removing the collected impurities is also very convenient. For installation and fixation, the temporary collection box 904 is directly inserted into the loading slot 902 in the fixing strip 901, ensuring that the second positioning magnetic piece 907 on the cover plate 906 contacts and adheres to the first positioning magnetic piece 903 in the loading slot 902, thus achieving quick installation. To clean the debris and impurities collected in the temporary collection box 904, the fixed connection between the cover plate 906 and the temporary collection box 904 must be released. After releasing the cover plate 906, it can be removed. Finally, the debris and impurities in the temporary collection box 904 can be removed. The debris and impurities can be cleaned up. When replacing the temporary collection boxes 904 at different positions on the main body of the transmission belt 808, the transmission roller 804 and the main body of the transmission belt 808 are driven by the control handle 805, which in turn moves the position of the temporary collection box 904 on the main body of the transmission belt 808. When a temporary collection box 904 needs to be removed, the temporary collection box 904 at the corresponding position is adjusted to the top position of the main body of the transmission belt 808, so that the operator can operate it. When the temporary collection box 904 is adjusted to the top position of the main body of the transmission belt 808, the operator can directly pull the temporary collection box 904 out of the loading tank 902, clean up the stored debris and impurities, and then insert the temporary collection box 904 into the corresponding loading tank 902.

[0043] The position of the temporary collection box 904 is controlled by adjusting the handle 805 to drive the transmission roller 804 and the transmission belt body 808. Specifically, when the temporary collection box 904 passes the bottom of the transmission belt body 808, to prevent debris and impurities in the collection box 904 from falling into the material passage 905, an auxiliary structure is provided at the inner opening of the material passage 905. This auxiliary structure includes a tapered tube head 1001, an annular groove 1002, and a support bar 1003. One end of the tapered tube head 1001 is fixedly installed at the inner opening of the material passage 905, and an annular groove 1002 is provided on the side wall of the tapered tube head 1001. Support bars 1003 are symmetrically fixed in the through groove 1002. The annular through groove 1002 is inclined. The tapered tube head 1001 and the material passage hole 905 are arranged in the same number of sets. That is, the small end of the tapered tube head 1001 is located inside the temporary collection box 904. The annular through groove 1002 is provided on the side wall of the temporary collection box 904. On the one hand, when the temporary collection box 904 passes the bottom position of the transmission belt body 808, it is necessary to avoid the stored debris and impurities from flowing out of the material passage hole 905. On the other hand, the annular through groove 1002 on the side wall of the tapered tube head 1001 is intended to avoid affecting the collection of externally splashed debris and impurities.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
