Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

The present invention will be described in detail with reference to fig. 1 to 7. The utility model relates to a ration sanding equipment, including unwinding device 1, first feeding device 2, sanding device 3, operation platform 4, second feeding device 5 and the take-up device 6 that sets gradually.

After being led out from the unwinding device 1, the fabric 9 is fed to the sanding device 3 through the first feeding device 2 for sanding treatment, passes through the lower part of the operation platform 4 to the second feeding device 5, and is wound into a roll through the winding device 6. The unwinding device 1 and the winding device 6 used are prior art and will not be described in detail.

The sanding device 3 comprises a sanding belt 31 and a first movable guide roller 34; the sanding belt 31 is sleeved outside the sanding driving roller 32 and the sanding driven roller 33. The sanding drive roll 32 is used to be rotated by a power source.

Two ends of the sanding driving roller 32 are provided with air cylinders for adjusting the distance between the first movable guide roller 34 and the sanding belt 31, and the distance is the thickness of the fabric.

And two ends of the first movable guide roller 34 are provided with rotary adjusting devices for adjusting the sanding height of the fabric. Further, the rotation adjusting device comprises a screw rod pair connected with the end part of the first movable guide roller 34, and the other end of the screw rod pair is connected with a speed reducer and a rotation driving device. The rotary drive is a hand wheel, on which a handle is arranged. The first movable guide roller 34 can be driven to move through the speed reducer and the screw rod pair by rotating the hand wheel, so that fine adjustment of the first movable guide roller 34 can be realized, and the fine adjustment interval is the height of sanding.

In the present invention, the first feeding device 2 and the second feeding device 5 have the same structure, and the structure of the second feeding device 2 is taken as an example for illustration. The first feeding device 2 comprises a first cloth guide roller 21 and two second cloth guide rollers 22, the diameter of the first cloth guide roller 21 is at least twice of that of the second cloth guide rollers 22, and the wrapping angle of the fabric 9 and the first cloth guide roller 21 is larger than 180 degrees; the surface of the first cloth guide roller 21 is rough, and the surface of the second cloth guide roller is smooth 22; the first cloth guide roller 21 is driven to rotate by a power source. The rotation of first fabric guide roller 21 can drive the rotation of surface fabric because its coarse surface to its parcel angle is great, and further improved the frictional force between first fabric guide roller 21 and surface fabric 9.

In order to further adjust the tension of the fabric 9 entering the sanding area, a second movable guide roller 35 is arranged below the first movable guide roller 34, and the second movable guide roller 35 is driven by an air cylinder to move along the horizontal direction and is used for adjusting the tension.

In order to enable the cloth surface of the fabric 9 to be smoother when the fabric enters the sanding area, a tentering roller 37 is arranged below the second movable guide roller 35, one part of the Zhang Fu roller 37 is provided with smooth bulges which are spirally distributed anticlockwise, and the other part of the roller 37 is provided with smooth bulges which are spirally distributed clockwise.

Furthermore, in order to adjust the tension of sanding belt 31, a movable tension adjustment roller 36 is provided inside sanding belt 31 for adjusting the tension of sanding belt 31.

When the fabric 9 is sanded, dust can be generated, and certain influence is exerted on the health of operators. In order to reduce the diffusion of dust in the operation workshop, a first dust suction device 10 is arranged above a sanding area formed by the sanding belt 31 and the first movable cloth guide roller 34, a second dust suction device 11 is arranged below the sanding area, the two dust suction devices are similar in structure and respectively comprise a hollow shell which gradually shrinks, one end of the hollow shell is provided with a dust suction hole 12, the other end of the hollow shell is provided with a suction nozzle 13, and the suction nozzle 13 is connected with the suction device and can suck the dust at the position of the dust suction hole 12, so that the dust cannot diffuse in the operation workshop to affect operation workers.

When sanding is performed for a long time, the sanding belt 31 is in contact with the fabric 9 for sanding, so that the heating phenomenon can occur, and the sanding quality is affected. In order to reduce the temperature of sanding belt 31, a refrigerating device 301 is connected to one end of sanding drive roller 32 via a liquid inlet pipe 302 and a liquid outlet pipe 303. The cooling medium used in the refrigeration apparatus 301 is water.

A liquid inlet 321 and a liquid outlet 322 are arranged at the end part of the sanding driving roller 32, the liquid inlet 321 is communicated with the liquid inlet pipe 302, and the liquid outlet 322 is communicated with the liquid outlet pipe 322. The other end of the liquid inlet 321 is communicated with an outer spiral pipe 323, and the other end of the liquid outlet 322 is communicated with an inner spiral pipe 324. The cooling medium passing through the refrigerating device 301 enters the outer spiral pipe 323 through the liquid inlet pipe 302 and the liquid inlet 321, and the temperature of the surface of the sanding driving roller 32 is reduced by the cooling medium in the outer spiral pipe 323, so that the temperature of the frosting Mao Shadai is reduced. After cooling the surface of the sanding drive roll 32, the cooling medium enters the inner spiral tube 324 from the outer spiral tube 323, and the temperature of the cooling medium inside the inner spiral tube 324 increases.

A layer of heat insulating material 325 is further disposed between the inner spiral pipe 324 and the outer spiral pipe 323, so that heat exchange does not occur between the inner spiral pipe 324 and the outer spiral pipe 323, and the temperature of the cooling medium in the outer spiral pipe 323 is prevented from increasing. And the inner spiral tube 324 and the outer spiral tube 323 exhibit opposite spirals.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
