TECHNICAL FIELD

[0001] The utility model relates to a lens edger technical field, specifically to an eye -glasses lens edger's peculiar smell pumping system. BACKGROUND

[0002] The edge processing of the spectacle lens is the key link in the spectacle manufacturing and the matching process, and is usually completed by the special lens edger. However, the existing spectacle lens edger generally has peculiar smell diffusion problem when working, which causes significant adverse effects on the working environment and personnel health, and is specifically shown in the following aspects:

[0003] The traditional spectacle lens edger design mainly focuses on the grinding precision and efficiency, and generally lacks the integrated type and the processing system specially aiming at the grinding peculiar smell. In the process of grinding the lens (especially the resin lens) or PC lens, the high-speed friction between the grinding wheel and the material can produce peculiar smell gas containing organic volatile matter, dust, burnt smell and the like, and the equipment manufacturer and the user usually only rely on the natural ventilation or simple exhaust fan of the workshop or working place to try to disperse the peculiar smell.

[0004] During the operation of the existing equipment, these generated peculiar smell gas lacks effective control and guidance, and often directly diffuses into the working environment around the equipment. This not only leads to the deterioration of the air quality of the working area, produces the unpleasant smell, but also more likely to pose a potential threat to the respiratory system health of the operators and the surrounding personnel in the environment for a long time. SUMMARY

[0005] The utility model aims at the problem that the lens edger lacks peculiar smell pumping system in the prior art, and provides a peculiar smell pumping system of spectacle lens edger.

[0023] Explanation of reference signs: edging machine 1, grinding cavity 11, negative pressure suction assembly 2, exhaust channel 21, exhaust groove 211, air inlet 2111, cavity cover plate 212, exhaust connector 22, air guide pipe 23, air suction device 24. DETAILED DESCRIPTION

[0024] Referring to Figures 1-4 , the technical solution adopted in the present embodiment is: an odor extraction system of an eyeglass lens edging machine, which comprises an edging machine 1 and a negative pressure suction assembly 2 arranged on a grinding cavity 11 in the edging machine 1.

[0025] The specific negative pressure suction assembly 2 comprises an exhaust channel 21, an exhaust connector 22, an air guide pipe 23 and an air suction device 24. The exhaust channel 21 is provided with two exhaust channels 21 respectively located at two ends of the grinding cavity 11, and the end of the exhaust channel 21 is connected with the air suction device 24 through the exhaust connector 22 and the air guide pipe 23.

[0026] More specifically, the exhaust channel 21 comprises an exhaust groove 211 and a cavity cover plate 212. The exhaust groove 211 is provided with a plurality of air inlets 2111 on the side facing the grinding cavity 11 and a slot opening (not marked in the figure) facing the cavity cover plate 212, and the exhaust groove 211 is located on the side wall of the grinding cavity 11 and cooperates with the cavity cover plate 212 installed on the edging machine 1 to form the exhaust channel 21.

[0027] Working state one: grinding operation mode (cavity cover plate 212 closed)

[0028] When the cavity cover plate 212 is closed and the grinding program is started, the high-speed airflow of the air suction device 24 only enters the air duct through the air inlet. At this time, the dust odor generated by grinding is limited in the closed cavity, and the double exhaust channels 21 form a convection at both ends of the cavity to eliminate the airflow dead angle.

[0029] Working state two: maintenance and cleaning mode (cavity cover plate 212 opened)

[0030] After the work is completed, the cavity cover plate 212 is manually opened to expose the entire exhaust groove 211, and the remaining gas and the gas floating in the air are sucked.

[0031] In another embodiment, the air inlet 2111 is connected with: a ring-shaped air suction cover module, in a 360° surrounding structure, for forming a closed suction space around the pollution source, directly sucking into the cover, source blocking, and minimum escape rate, suitable for high-concentration pollution of fixed points.

[0032] In another embodiment, the air inlet 2111 is connected with: an adjustable angle air suction arm module, adopting a multi-joint mechanical arm structure, and being provided with an air suction port at the tail end, so that the tail end air suction port is accurately positioned to the closest position from the grinding point. Flexible response to different shapes of lenses or non-standard grinding paths.

[0033] In another embodiment, the air inlet 2111 is connected with: a following dynamic air suction module, which is linked with the edging machine 1, dynamically sucks in real time according to the edging process, and is always kept above or at the side of the pollution source. (The following dynamic air suction module is a conventional technical means in the art, and thus will not be described here.)

[0034] In another embodiment, the exhaust passage 21 is a magnetic positioning air suction port structure, including a magnetic adsorption component and a detachable air duct, for quickly positioning and installing to a specified area of the workbench surface. (The magnetic positioning air suction port structure is a conventional technical means in the art, and thus will not be described here.)

[0035] In another embodiment, the exhaust passage 21 is a hidden slit air suction structure, and the exhaust passage 21 is embedded inside the grinding cavity 11 in the edging machine 1, and the slit opening continuously extends along the edge of the processing area to form a negative pressure capture belt. (The hidden slit air suction structure is a conventional technical means in the art, and thus will not be described here.)

[0036] Working principle of the utility model:

[0037] 1. Grinding start and pollution generation:

[0038] When the edging machine 1 starts processing the lens, the grinding tool (such as a grinding wheel) contacts the lens to generate high-temperature friction, releasing mixed pollutants containing resin dust, metal particles, cutting fluid volatiles and other odors.

[0039] 2. Activation of the negative pressure system:

[0040] The air suction device 24 is started: the edging machine 1 operation signal triggers or the staff manually starts the air suction device 24 to work, and a stable negative pressure is established in the exhaust passage 21.

[0041] 3. Gas collection and transmission:

[0042] The pollutants enter the exhaust groove 211 through the air inlet 2111, and the inhaled air flow is efficiently collected to the exhaust joint 22. Then the gas is transported to the air extraction device 24 through the air guide pipe 23. The air extraction device 24 sends the contaminated gas to the subsequent processing unit (such as an activated carbon filter, an electrostatic precipitator or a spray tower) to remove harmful particles and odor components. (The subsequent processing unit is a conventional technical means in the art, and therefore will not be described here.)

[0043] The purified gas meets the environmental protection standard and is safely discharged to the outdoor or the workshop ventilation system through the pipeline.

[0044] 4. Continuous circulation and shutdown:

[0045] During the edge grinding process, the negative pressure suction continuously operates to form a dynamic air flow barrier to prevent the pollutants from spreading in the cavity.

[0046] After the grinding is completed, the air extraction device 24 is delayed to be closed (to ensure that the residual pollutants are removed), and the system is on standby.

[0047] The above description is only used to explain the technical scheme of the present application but not to limit it. Other modifications or equivalent replacements to the technical scheme of the present application made by those skilled in the art should be covered in the scope of the claims of the present application as long as they do not depart from the spirit and range of the present application.
