Description

Technical Field

[0001] The utility model relates to the technical field of capacitor element processing equipment, in particular to a smoke purification device for a laser engraving machine. Background Art

[0002] Laser engraving is based on numerical control technology and uses laser as the processing medium. The physical transformation of the processing material that melts and vaporizes instantly under the irradiation of laser engraving can achieve the purpose of laser engraving. Since the laser will vaporize the surface of the workpiece during the processing, a large amount of smoke will be generated. The smoke components generated by the laser burning the workpiece are different depending on the processing material, resulting in toxic and harmful components in the smoke, especially in the processing of capacitors.

[0003] However, since traditional laser engraving equipment usually does not have smoke exhaust and purification functions, a large amount of smoke is directly discharged into the factory or outdoors, causing damage to the surrounding environment. There is a long-term risk of causing harm to the body. The smoke is easily inhaled by the operator in large quantities, causing harm to the operator's body.

[0004] At present, Chinese patent publication number CN219561843U discloses a small purifier and a laser engraving machine using the small purifier, which includes: a shell, a filter element installed in the shell, a fan arranged at the bottom of the shell and used to generate suction, a bottom cover installed at the bottom of the shell and used to fix the fan, an upper cover installed on the shell and used to install a connecting hose, and at least two connecting locks arranged on the side wall of the shell and used to connect the upper cover, and the other end of the hose is connected to the laser engraving machine.

[0005] Although this small purifier can purify the smoke from the laser engraving machine, the device purifies the smoke by setting a filter element in the shell. However, when the capacitor is processed by the laser engraving machine, metal particles enter the smoke, which can easily cause the filter element to be blocked. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a laser engraving machine exhaust gas purification device to solve the problem of poor smoke purification effect and easy clogging of the engraving machine when processing capacitor elements in the prior art.

[0007] To achieve the above-mentioned purpose and other related purposes, the utility model provides a laser engraving machine exhaust gas purification device, including a connecting pipe connected to the laser engraving machine, a fan connected to the connecting pipe for extracting smoke, and a dust-free bag arranged at the air outlet of the fan, the dust-free bag having a connecting port, the connecting port being sleeved outside the air outlet of the fan, and a connecting component for fixing the dust-free bag and the fan being arranged on the connecting port, and an opening and closing component for opening the dust-free bag being also arranged on the dust-free bag.

[0008] By adopting the above technical scheme, when the engraving machine processes capacitor elements, the smoke in the engraving machine can be extracted and discharged into the dust-free bag at the air outlet of the fan through the cooperation connection of the fan, and the smoke is filtered by the dust-free bag. The low density of the dust-free cloth is utilized to prevent metal particles in the smoke from leaving the dust-free bag through the smoke, thereby achieving the filtration of metal particles. Moreover, the bag method is adopted to prevent metal particles from blocking the air outlet channel of the smoke, thereby ensuring the purification effect of the smoke. The dust-free bag can be opened by the opening and closing component, and the inside of the dust-free bag can be cleaned, which is convenient for later maintenance. The dust-free bag has a low cost and is easier to promote and use.

[0009] In one embodiment of the utility model, the cross-sectional shape of the dust-free bag is set to be a rectangle, the connecting port is located on the left-right symmetrical plane of the dust-free bag, and a connecting sleeve extending outwardly for setting an air outlet is also provided at the connecting port.

[0010] By adopting the above technical solution, the dust-free bag is designed into a rectangular shape, which is more convenient for the production and processing of the dust-free bag, and makes the smoke escape more and less prone to clogging. In addition, by providing a connecting sleeve at the connecting port, it is easier to connect the dust-free bag to the fan and facilitate installation by the staff.

[0011] In one embodiment of the present invention, the connection assembly includes an upper clamping hoop sleeved outside the connection sleeve, a lower clamping hoop arranged opposite to the upper clamping hoop, and a fastener connecting the upper clamping hoop and the lower clamping hoop.

[0012] By adopting the above technical solution, the dust-free bag and the fan are fixedly connected by a clamp, so that the connection between the two is more reliable and the connection is more tightly sealed, so that the dust-free bag is not easy to detach, and the staff only needs to adjust the fasteners to replace the dust-free bag, which is simple and convenient to operate.

[0013] In one embodiment of the present invention, the opening and closing assembly includes an opening disposed on a side of the dust-free bag, chain belts disposed oppositely on two sides of the opening, and a zipper head engaged with the chain belts.

[0014] By adopting the above technical solution, the dust-free bag can be quickly opened and closed by a zipper, which is convenient for the staff to operate and is more conducive to cleaning the dust-proof bag.

[0015] In one embodiment of the present invention, the length of the chain matches the length of the side of the dust bag.

[0016] By adopting the above technical solution, the opening of the dustproof cloth bag can be made larger, and the side wall of the dustproof cloth bag can be fully opened, making it easier to clean the inside of the dustproof cloth bag.

[0017] In one embodiment of the present invention, the chain belt is a sealed chain belt, and the zipper head is a sealed zipper head that cooperates with the sealed chain head.

[0018] By adopting the above technical solution, the sealed chain belt and zipper head can be used to make the sealing better, making it difficult for smoke to escape from the zipper, thereby improving the purification effect of the smoke.

[0019] In one embodiment of the present invention, the dust-free bag is an anti-static dust-free bag.

[0020] By adopting the above technical solution, the use of anti-static dust-free bags can prevent the generation and accumulation of static electricity, which is more suitable for the production environment of capacitor components.

[0021] As described above, the laser engraving machine exhaust gas purification device of the utility model has the following beneficial effects: when the engraving machine processes capacitor elements, the smoke in the engraving machine can be extracted and discharged into the dust-free bag at the air outlet of the fan through the connection with the fan, and the smoke is filtered by the dust-free bag. The small density of the dust-free cloth is utilized to prevent the metal particles in the smoke from leaving the dust-free bag through the smoke, thereby achieving the filtration of the metal particles. Moreover, the bag method is adopted to prevent the metal particles from blocking the air outlet channel of the smoke, thereby ensuring the purification effect of the smoke. The opening and closing assembly can then be used to open the dust-free bag and clean the inside of the dust-free bag, which is convenient for later maintenance. Moreover, the dust-free bag has a low cost and is easier to promote and use. BRIEF DESCRIPTION OF THE DRAWINGS
