Description

Technical Field

[0001] The utility model belongs to the technical field of bamboo chopstick processing, and particularly relates to a dust removal device for bamboo chopstick production. Background Technique

[0002] First of all, suitable bamboo raw materials need to be selected. Usually, bamboo varieties that are mature in growth, tough in texture, and straight in grain are chosen. After the bamboo is felled, it needs to go through a series of pretreatment steps, including removing the branches, leaves, and bamboo joints of the bamboo, cutting the bamboo into appropriate lengths. Next is the preliminary processing link, splitting the bamboo into bamboo boards, and then polishing the bamboo boards by mechanical or manual means to make their surfaces smooth, removing burrs and sharp parts. After that is the shaping stage. According to the designed chopstick specifications and shapes, the bamboo boards are cut, sharpened, etc. to initially have the shape of chopsticks. After the initial shaping is completed, fine processing is also required, such as further polishing the surface of the chopsticks to make them smoother and more delicate, improving the comfort of use. In order to increase the beauty and durability of the bamboo chopsticks, polishing, painting, or other surface treatment processes may be carried out. Finally, after quality inspection, ensuring that the dimensions, appearance, strength, etc. of the bamboo chopsticks meet the relevant standards, they are packaged for transportation and sales;

[0003] Currently, during the processing of bamboo chopsticks, after the preliminary treatment of the bamboo boards, a large amount of dust, broken bamboo, and sawdust are extremely likely to adhere to the outer surface of the bamboo boards. In the prior art, a Chinese patent with the publication number "CN218590008U" discloses a dust removal device for a numerical control processing center for wood and bamboo processing, which includes a displacement seat. An elevating assembly is arranged on the displacement seat. A processing seat is arranged between the two displacement seats. One end of a connecting air duct is communicated with the upper end of the processing seat. One end of the numerical control processing center body is fixedly installed with a dust removal box. The other end of the connecting air duct is communicated with the dust removal box. The lower end of the processing seat is fixedly connected with an annular protective cover. A movable cover is sleeved on the lower end of the protective cover. A cleaning brush is fixedly installed on the lower surface of the movable cover. The lifting block drives the processing seat to move downward to realize the processing of the surface of the wood and bamboo materials. And the movable cover and the wood and bamboo materials are mutually attached, so that the protective cover and the movable cover form a closed isolation for the processing area, preventing debris from flying everywhere, facilitating the dust removal work. At the same time, when the processing seat moves, the cleaning brush cleans the surface of the wood and bamboo materials, ensuring the dust removal effect;

[0004] During the actual application of the above device, dust is collected by means of suction by a blower. However, in the specific cleaning process, there are obvious defects. The device lacks a corresponding special cleaning structure and simply relies on the negative pressure generated by the suction fan to assist in dust collection. Since the surface of the fluff is very fine, it is extremely easy to firmly adhere to the outer surface of the bamboo board. For the fluff that is stably attached to the outer surface of the bamboo board, it is obvious that simply using the method of suction dust removal is difficult to effectively remove it. Therefore, it is impossible to quickly and effectively clean the fluff during the overall cleaning process. At the same time, during the process of cleaning and dust removal, it is not convenient to quickly synchronously clean both sides of the bamboo board. In summary, the device has certain limitations and deficiencies, and there is an urgent need to improve and optimize it. Summary of the Invention

[0030] By setting up the dust removal device 7 in cooperation with the cleaning component 6, during the use of this device, the electric push rod 5 can be started to operate. The electric push rod 5 drives the mounting frame 61 to move downward. When the mounting frame 61 moves downward, it can drive the cleaning brush roller 62 to move downward and fit the top of the bamboo board. The cleaning brush roller 62 at the bottom can stably fit the bottom of the bamboo board. At this time, by starting the first motor 63 to operate, the first motor 63 drives the cleaning brush roller 62 to rotate. At this time, the cleaning brush plate fits the top and bottom of the bamboo board, and the top and bottom of the outer surface of the bamboo board can be synchronously brushed and cleaned, which can avoid the situation of wool residue on the outer surface of the bamboo board. And during its application process, after the bamboo chips are collected, the magnetic attraction plate 78 can adsorb and fix the sealing cover 77 on the top of the filter box 72. If it needs to be disassembled, only need to lift the indentation 79 to assist in pulling out the filter screen frame 76 inside the filter box 72, so that the whole device can quickly disassemble and separate the filter screen frame 76, making the whole device have strong dust-proof performance, improving the convenience of cleaning bamboo chips of the whole device, and improving the convenience during the whole use period of the device.
