[0002] In the production process of medical devices, lathes are required to ensure the precision of parts. When turning parts, especially in the case of dry turning, not only dust but also a certain amount of smoke will be generated. In order to avoid environmental pollution caused by the splashing of debris and dust, dust removal is required during the lathe processing;

[0003] In the prior art, for example, a utility model with publication number 202321726234.5 discloses a dust removal device for CNC lathe processing. The device comprises a brake servo motor, an L-shaped tube, a transition dust removal cylinder, a drainage output component, a curved support, a collecting component, a filtering component and a self-cleaning component, which constitute a multifunctional dust removal device. When used in combination with a CNC lathe, in addition to being able to perform negative pressure drainage and filtration on the dust generated during the production process of the CNC lathe, the dust removal device itself has a self-cleaning effect, and has the effect of continuous operation and high efficiency.

[0004] Similar to the above application, there are still some shortcomings:

[0005] Although the linkage method can simultaneously control the rotation of the fan blades and the cleaning plate to self-clean the surface of the filter, the high-speed operation of the motor will cause the brush plate to continuously rub against the surface of the filter, increasing the wear rate of the filter and the brush plate, and affecting the service life of the brush plate and the filter;

[0006] Therefore, an environmental protection device for a medical device production lathe is designed to optimize the above-mentioned problems. Utility Model Content

[0007] The main purpose of the utility model is to provide an environmental protection device for a lathe producing medical equipment, which fixes a through pipe at the middle position of the filter and arranges a telescopic mechanism consisting of a baffle, a rotating rod, a limit block and a spring inside the through pipe. When there are many impurities on the surface of the filter, the end of the mounting tube away from the air intake port is in a negative pressure state, and the baffle controls the rotating rod to move toward one end of the motor, and fits the brush plate to the top of the filter. At the same time, the connecting mechanism consisting of a plug rod and a plug sleeve between the rotating rod and the shaft rod is plugged in, and the shaft rod and the rotating rod are connected to control the brush plate to self-clean the surface of the filter, and the brush plate automatically resets after cleaning is completed, thereby ensuring the service life of the filter and the brush plate, and having higher practicality. By arranging a storage bin for storing activated carbon at the end of the mounting tube away from the air intake port, deodorization can be performed at the same time after the dust and impurities are filtered out, and the environmental protection effect is better.

DETAILED DESCRIPTION

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1-Figure 4 As shown, the present embodiment provides an environmental protection device for a medical device production lathe, including a lathe body 1, a mounting tube 2 which is in communication with the inside of the lathe body 1 is installed on the top of the shell of the lathe body 1, an air inlet 3 is opened at the bottom of the mounting tube 2, a filter 4 is vertically installed at one end of the mounting tube 2 near the air inlet 3, a motor 5 with an output end facing the filter 4 is installed at the middle position of the mounting tube 2, a shaft 6 is installed on the output shaft of the motor 5, a fan blade 7 is installed on the shaft 6, and a filter 4 is fixed at the middle position of the filter 4. A through pipe 10 is provided, and a baffle 11 is slidably provided inside the through pipe 10. A limit block 13 is provided at one end of the through pipe 10 near the shaft 6. A spring 14 is provided between the baffle 11 and the limit block 13. A rotating rod 12 is rotatably installed at the middle position of the baffle 11. A brush plate 8 is fixed to one end of the rotating rod 12 near the air intake port 3. A collecting frame 9 is slidably provided at the inner bottom of the mounting tube 2 and below the brush plate 8. The rotating rod 12 and the shaft 6 are located on the same straight line, and a connecting mechanism is provided between the end of the rotating rod 12 and the shaft 6.

[0025] Overall working principle: During the processing of medical device parts by the lathe body 1, some dust particles and smoke will be generated. At this time, the motor 5 is turned on to control the rotation of the shaft 6. The shaft 6 will drive the fan blades 7 to rotate at high speed, generating negative pressure inside the mounting tube 2, absorbing the debris and smoke inside the lathe body 1, and filtering them through the filter 4. After long-term use, the surface of the filter 4 is covered with debris and the air permeability is low. Since the rotation speed of the fan blades 7 is fixed, the pressure inside the mounting tube 2 increases, causing the baffle 11 to slide inside the through pipe 10. While the baffle 11 slides, it will control the movement of the rotating rod 12, fit the brush plate 8 with the surface of the filter 4, and connect it to the end of the shaft 6 using a connecting mechanism. At this time, the start-up of the motor 5 will simultaneously drive the brush plate 8 on the rotating rod 12 to rotate, and clean the outside of the filter 4. After the filter 4 is cleaned, the air permeability increases, and the baffle 11 is reset under the action of the spring 14, and the plug 15 is separated from the shaft 6.

[0026] In this embodiment, the connection mechanism includes an insertion rod 15 and a sleeve 16. The insertion rod 15 is fixed to the end of the rotating rod 12. The insertion rod 15 is in the shape of a quadrangular prism. The sleeve 16 is fixed to the end of the shaft 6. The insertion rod 15 and the sleeve 16 are plugged together.

[0027] Partial working principle: When the rotating rod 12 moves horizontally, the insertion rod 15 will be inserted into the inside of the insertion sleeve 16 to connect the rotating rod 12 and the shaft rod 6. The insertion rod 15 is a quadrangular prism, so the rotation of the shaft rod 6 will drive the rotating rod 12 to rotate.

[0028] In this embodiment, a protective net 19 is provided at one end of the installation tube 2 away from the air inlet 3 , and the outer side of the protective net 19 is in contact with the inner wall of the installation tube 2 .

[0029] Partial working principle: By using the protection net 19, the interior of the installation pipe 2 can be protected.

[0030] In this embodiment, a storage bin 17 is provided inside the installation tube 2 between the motor 5 and the protective net 19 . The storage bin 17 is filled with activated carbon 18 , and a cover plate is provided on the top of the storage bin 17 .

[0031] Partial working principle: Since the extracted gas contains smoke caused by dry cars, the use of activated carbon 18 can effectively remove odors and has a better environmental protection effect.

[0032] In this embodiment, there is a gap between the outer side of the filter screen 4 and the bristles of the brush plate 8, and the shape of the filter screen 4 is circular.

[0033] Partial working principle: When the filter screen 4 is not cleaned, the brush plate 8 is separated from the filter screen 4, which effectively prevents the brush plate 8 from blocking the filter screen 4 and ensures the air permeability of the filter screen 4.

[0034] In this embodiment, a sealing ring is provided between the outer side of the baffle 11 and the inner wall of the through pipe 10 , and the sealing ring is fixed on the baffle 11 .

[0035] Partial working principle: During the use of the baffle 11, the use of the sealing ring ensures the sealing effect of the baffle 11 on the inside of the through pipe 10, effectively avoiding gas leakage and ensuring that the baffle 11 can move stably.

[0036] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
