Abstract

The utility model relates to a sand proof structure for a cutting roller box of a filter multi-wire cutting machine, and the sand proof structure is used in a filter multi-wire cutting machine. The sand proof structure comprises a box body, a cutting roller and a front end cover, wherein the cutting roller is arranged on the box body, the front end cover is sleeved on the cutting roller and is fixed with the box body. The sand proof structure is characterized by further comprising a sand proof shield and a sand proof ring, wherein the sand proof shield is sleeved outside the front end cover and is fixed with the box body, sand outlets are opened in the sand proof shield, the sand proof ring is sleeved and fixed on the cutting roller, a gap is arranged between the sand proof ring and the sand proof shield, annular sand proof grooves are opened in the front end cover, and the sand proof grooves are communicated with the gap and the sand outlet holes. According to the sand proof structure, the structure design is reasonable, crystal sand can be prevented from entering the gap between the cutting roller and the box body, and further the crystal sand is prevented from entering a bearing, so that the bearing is protected.

Description

The cutting roller case sand prevention structure of optical filter multi-line cutting machine

Technical field

The utility model relates to a kind of cutting roller case sand prevention structure of optical filter multi-line cutting machine, is used for the optical filter multi-line cutting machine.

Background technology

The optical filter multi-line cutting machine is that a kind of cutting roller that utilizes drives the wire high-speed motion, the optical filter crystal slab once is cut into simultaneously the machine of tens plate sheets.Cutting roller is installed on the casing.Drive end bearing bracket is sleeved on the cutting roller, and fixes with casing, and drive end bearing bracket plays the effect that is fixedly mounted on the bearing on the cutting roller.In the process of cutting optical filter crystal slab, the optical filter crystal slab is understood many quartzy fine sands of emerging because cut at cutting part, and these quartzy fine sands can enter into through the space between cutting roller and the casing on the bearing, influence the life-span of bearing.

The utility model content

The utility model technical problem to be solved is to overcome deficiency of the prior art and a kind of reasonable in design is provided, can prevents that quartzy fine sand from getting into the cutting roller case sand prevention structure of the optical filter multi-line cutting machine of bearing.

The technical scheme that the utility model solves the problems of the technologies described above employing is: a kind of cutting roller case sand prevention structure of optical filter multi-line cutting machine comprises casing, cutting roller, drive end bearing bracket; Cutting roller is installed on the casing; Drive end bearing bracket is sleeved on the cutting roller, and fixes with casing; It is characterized in that: also comprise anti-sand cover and sand prevention circle; Anti-sand cover is sleeved on outside the drive end bearing bracket, and fixes with casing, on anti-sand cover, has out husky hole; Sand prevention snare dress is fixed on the cutting roller, has the gap between itself and the anti-sand cover; On drive end bearing bracket, have the sand prevention groove of annular, the sand prevention groove respectively with the gap with go out husky hole and communicate.

The cross section of the described sand prevention groove of the utility model is an arc.

The utility model compared with prior art has following advantage and effect: reasonable in design can prevent that quartzy fine sand from can get into the space between cutting roller and the casing, and then prevent that quartzy fine sand from getting into bearing, protected bearing.

The specific embodiment

Below in conjunction with accompanying drawing and through embodiment the utility model is described further.

Referring to Fig. 1～Fig. 8, the utility model embodiment comprises casing 1, cutting roller 2, drive end bearing bracket 3, anti-sand cover 4, sand prevention circle 5.

Cutting roller 2 is installed on the casing 1.Drive end bearing bracket 3 is sleeved on the cutting roller 2, and fixing with casing 1, and drive end bearing bracket 3 plays the effect of the bearing 9 that is fixedly mounted on the cutting roller 2.

Anti-sand cover 4 is sleeved on outside the drive end bearing bracket 3, and fixes with casing, on anti-sand cover 4, has out husky hole 10.

Sand prevention circle 5 suits also are fixed on the cutting roller 2, have gap 6 between itself and the anti-sand cover 4, and like this, sand prevention circle 5 does not contact with anti-sand cover 4, can not wear and tear in the rotation at a high speed with cutting roller 2.

On drive end bearing bracket 3, have the sand prevention groove 7 of annular, sand prevention groove 7 respectively with gap 6 with go out husky hole 10 and communicate.The cross section of sand prevention groove 7 is an arc.

During use, quartzy fine sand enters into sand prevention groove 7 through

gap

6, and 7 pairs of quartzy fine sands of sand prevention groove play inhibition.Because action of centrifugal force, quartzy fine sand can be discharged through going out husky hole 10 again.Like this, can prevent that just quartzy fine sand from getting into the space 8 between cutting roller 2 and the casing 1, and then prevent that quartzy fine sand from getting into bearing 9, protected bearing 9.
