It measures, gas in heated protective cover 31, enhances air pressure in protective cover 31, pass the gas through 33 flowing of opening, drive 34 turns of flabellum
Dynamic, the rotation of flabellum 34 can reinforce the flowing of gas, can effectively be radiated to light source 32 by air-flow.
As one embodiment of the present invention, 1 upper surface of pedestal opens up fluted 14；It is evenly arranged in groove 14
There is closed bucket 15；Stripper plate 16 is slidably connected in the closed bucket 15；The "T"-shaped design of the stripper plate 16, and upper end is worn
Cross closed bucket 15, lower end is connected by second spring 17 and closed 15 bottom of bucket, and when stripper plate 16 is initial props up the first spring
25；31 inner wall of protective cover has been evenly arranged port 35；15 internal cavity of closed bucket is connected to port 35；When work, produce
Product 5 are placed in 25 surface of the first spring by feeding inlet 21, since the both ends internal diameter of the first spring 25 differs, in the weight of product 5
Under power effect, it can be pressed down against the first spring 25, stripper plate 16 contacts 25 surface of the first spring when initial, under the first spring 25
It moves, stripper plate 16 is driven to move down, to squeeze closed 15 internal cavity of bucket, flow out sky intracavity gas by port 35, accelerate to protect
The flowing of 31 interior air-flow of shield to accelerate the rotation of flabellum 34, and then reinforces the cooling effect to light source 32.
As one embodiment of the present invention, the spring wire surface of first spring 25 has been evenly arranged double wedge；Institute
It states double wedge surface and is attached with the grains of sand；When work, the friction between the first spring 25 and product 5 can be enhanced by double wedge and the grains of sand
Power prevents from skidding in 5 transportational process of product, while the contact area of double wedge meeting larger production 5 and air, to accelerate product 5
Cooling rate.
As one embodiment of the present invention, collection chamber 26 is fixed at the top of the framework 2；It is equipped at the opening 33
Conduit；Conduit connection opening 33 and collection chamber 26, conduit are equipped with check valve, when guaranteeing that flabellum 34 rotates in opening 33, do not stop
To collection chamber 26 inflate；The collection chamber 26 is connected to dry ice maker 4；Connectivity part is equipped with pressure valve, when pressure reaches one
Pressure valve is opened when definite value, and gas makes dry ice pass through high-pressure nozzle 41 faster to be sprayed onto 5 surface of product, is cooled down to product 5；Work
When, product 5 is placed in flabellum 34 behind 25 surface of the first spring and rotates, collection chamber 26 is inflated, when product 5 right end with most
Most in short-term, 26 air pressure of collection chamber reaches maximum value to the distance between right end high-pressure nozzle 41, and air pressure valve is opened, and dry ice is sprayed on production
5 surface of product, product 5 continue to move to right, when the region that dry ice was sprayed on 5 surface of product will leave the sprayable area of high-pressure nozzle 41
When domain, 26 pressure of collection chamber reaches maximum value again, and pressure valve is opened, and effectively prevent the sprinkling of 5 surface dry ice of product non-uniform
Phenomenon makes 5 surface dry ice of product more evenly, cools down more thorough.
When work, motor 11 is rotated, and drives shaft 24 to rotate by the rope made of hemp 13, shaft 24 drives the first spring 25 when rotating
Rotation, product 5 are placed in 25 surface of the first spring by feeding inlet 21, since the both ends internal diameter of the first spring 25 differs, are producing
Under the gravity of product 5, it can be pressed down against the first spring 25, the first spring 25 moves down, and drives stripper plate 16 to move down, to squeeze
Closed 15 internal cavity of bucket flows out sky intracavity gas by port 35, accelerates the flowing of 31 interior air-flow of protective cover, meanwhile, light source 32
Amount of heat is generated in the course of work, gas in heated protective cover 31 enhances air pressure in protective cover 31, passes the gas through opening
33 flowings, drive flabellum 34 to rotate, are inflated to collection chamber 26, under the cooperation by two 25 uniform rotation of the first spring,
Landing will not be controlled while moving right product 5 at the uniform velocity, by the rotary transport of the first spring 25, make product 5 through too drastic
Optical generator 3 cut, when the distance between the right end of product 5 and right end high-pressure nozzle 41 most in short-term, 26 air pressure of collection chamber
Reach maximum value, air pressure valve is opened, and dry ice is sprayed on 5 surface of product, and product 5 continues to move to right, when dry ice was sprayed on 5 surface of product
Region when will leave the sprayable region of high-pressure nozzle 41,26 pressure of collection chamber reaches maximum value again, and pressure valve is opened,
It effectively prevent 5 surface dry ice of product to spray non-uniform phenomenon, makes 5 surface dry ice of product more evenly, cool down more thorough.

(34)；Light source (32) work, heated protective cover (31) interior gas enhance air pressure, and gas drives fan by opening (33) flowing
Leaf (34) rotation, flabellum (34) can reinforce the flowing of gas, effectively radiate to light source (32).
3. a kind of laser cutting machine according to claim 1, it is characterised in that: pedestal (1) upper surface offers recessed
Slot (14)；Closed bucket (15) have been evenly arranged in groove (14)；Stripper plate (16) are slidably connected in the closed bucket (15)；
The "T"-shaped design of the stripper plate (16), and upper end passes through closed bucket (15), lower end passes through second spring (17) and closed bucket (15)
Bottom is connected, and when stripper plate (16) is initial props up the first spring (25)；Protective cover (31) inner wall has been evenly arranged port
(35)；Closed bucket (15) internal cavity is connected to port (35)；When product (5) is placed in the first spring (25) surface, squeeze
First spring (25) makes port (35) outlet to squeeze closed bucket (15) internal cavity, accelerates air-flow flowing, accelerates flabellum
(34) it rotates, reinforces the cooling effect to light source (32).
4. a kind of laser cutting machine according to claim 1, it is characterised in that: the spring silk table of first spring (25)
Face has been evenly arranged double wedge；The double wedge surface is attached with the grains of sand；The first spring (25) can be enhanced by double wedge and the grains of sand and produced
Frictional force between product (5) prevents from skidding in product (5) transportational process, while double wedge can contact of the larger production (5) with air
Area, to accelerate the cooling rate of product (5).
5. a kind of laser cutting machine according to claim 1, it is characterised in that: be fixed with gas collection at the top of the framework (2)
Room (26)；Conduit is equipped at the opening (33)；Conduit connection opening (33) and collection chamber (26), conduit are equipped with check valve,
When guaranteeing opening (33) interior flabellum (34) rotation, ceaselessly collection chamber (26) are inflated；The collection chamber (26) and dry ice manufacture
Device (4) connection；Connectivity part is equipped with pressure valve, and when pressure reaches certain value, pressure valve is opened, and gas passes through dry ice faster
High-pressure nozzle (41) is sprayed onto product (5) surface, cools down to product (5), after collection chamber (26) interior gas just sprays, product (5)
When high-pressure nozzle (41) sprayable region will be left by having sprayed the region of dry ice, pressure valve reaches maximal pressure force value,
Jet again effectively prevent the sprinkling of product (5) surface dry ice uneven, cooling is caused to be not thorough.
