Description

Technical Field

[0001] The invention relates to the technical field of glass cleaning, in particular to a brush roller shaft head sealed waterproof internal circulation structure. Background Art

[0002] With the rapid development of the glass industry, the application of glass washing machines is becoming more and more extensive. In the process of cleaning glass, under the combined effect of high-pressure spray water and high-speed rotating brush roller, the water in the chamber will be randomly thrown out along the direction of the brush roller, and the thrown water will flow along the shaft head of the brush roller to the parts outside the cleaning chamber, which will not only cause waste of spray water, but also affect the appearance and life of the equipment. In addition, for the acid and alkali liquid cleaning process, the acid and alkali liquid will also corrode the equipment, which will cause greater safety hazards. The waterproof structure on the market usually uses a rubber ring on the shaft head of the brush roller in the chamber, but due to the high-speed rotation of the brush roller, water will still flow through the rubber ring along the inner wall of the chamber into the shaft head of the brush roller, and finally flow to the outside of the cleaning chamber.

[0003] In the prior art, in the Chinese utility model patent "Sealing Structure for End of Driving Roller of Glass Washing Machine" with announcement number CN201988552U, an inner baffle and an outer baffle are provided at the end of the water tank of the glass washing machine corresponding to the driving roller, and a sealing end plate is sealed on the outer baffle, and the end of the driving roller passes through the sealing end plates on the inner baffle and the outer baffle in turn, and a sealing retaining ring is fixedly connected to the part of the driving roller between the inner baffle and the outer baffle, and a V-shaped sealing ring is installed on the sealing retaining ring, and the lip of the V-shaped sealing ring is in contact with the inner side surface of the sealing end plate. When in use, the V-shaped sealing ring rotates with the driving roller and always maintains a contact seal with the inner side surface of the sealing end plate, which can prevent dust from outside the equipment from entering and water from inside the equipment from flowing out.

[0004] The above patent only solves the problem of sealing the gap at the junction of the water tank and the roller, and is not suitable for high-speed rotating brush rollers. When the brush roller rotates at high speed, the water on the brush will move in all directions, and the thrown water will flow along the shaft head of the brush roller to the parts outside the cleaning chamber. A small amount of water on the inner wall of the cleaning chamber will also flow into the shaft head of the brush roller and flow outward along the shaft head to the parts outside the cleaning chamber. Summary of the invention

[0005] The technical problem to be solved by the present invention is how to solve the problem of water leakage at the shaft head of the brush roller when the brush roller rotates at high speed.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0008] Furthermore, the sealing ring is interference fit with the shaft head of the brush roller.

[0009] Furthermore, the clamping plate is an upper and lower clamping groove structure with a through hole in the middle, and the shaft head of the brush roller passes through the through hole.

[0010] Furthermore, the clamping plate includes an end face 1 and an end face 2, the bell mouth of the inner sealing ring is in close contact with the end face 1, and there is a gap between the bell mouth of the outer sealing ring and the end face 2.

[0011] Furthermore, slots are provided on the side panels at both ends of the water bucket, and the clamping plate is inserted into the slots.

[0012] Furthermore, a plurality of drainage ports are provided on the side panels of the water bucket, and the drainage ports drain the water in the water diversion trough into the water bucket.

[0013] Furthermore, it also includes a bracket, and the brush roller assembly also includes a support seat, and both ends of the brush roller are fixed to the bracket through the support seat.

[0014] Furthermore, it also includes a spray assembly, which is fixed above the brush roller.

[0015] Compared with the prior art, the present invention provides a brush roller shaft head sealed waterproof internal circulation structure, which has the following beneficial effects:

[0016] In the present invention, at least two clamping plates are respectively sleeved on the shaft heads at both ends of the brush roller, the clamping plates are inserted into the water bucket, the shaft head of the brush roller rotates in the through hole of the clamping plates with a gap, the sealing ring rotates with the shaft head of the brush roller, the clamping plates play a role of dynamic sealing, and the bell mouths of at least two sealing rings are relatively sleeved on the shaft head of the brush roller and are located on both sides of the clamping plates. The sealing ring is a bell mouth structure, the bell mouth of the inner sealing ring is tightly attached to the clamping plate, and the bell mouths of the clamping plate and the inner sealing ring can block most of the water from flowing to the outside of the water bucket.

[0017] The bell mouth of the inner sealing ring is close to the cardboard, which is equivalent to the bell mouth of the inner sealing ring being close to the inner wall of the water bucket. A small amount of water on the inner wall will flow into the shaft head of the brush roller through the bell mouth of the inner sealing ring and flow outward along the shaft head. There is a gap between the bell mouth of the outer sealing ring and the cardboard. Since the width of the water diversion grooves on both sides of the water bucket is greater than the distance of the gap, the bell mouth of the outer sealing ring will lead the water flowing into the shaft head along the inclined surface of the bell mouth into the water diversion groove, and re-flow into the water bucket through the drainage ports on both sides of the water bucket, realizing internal circulation drainage, which can completely prevent water leakage, thereby preventing the water randomly thrown out by the high-speed rotation of the brush roller from flowing along the shaft head to the parts outside the water bucket, avoiding waste of spray water, and also avoiding affecting the appearance and life of the equipment. When using acid and alkali liquid to clean glass, avoid acid and alkali liquid corrosion of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0032] like Figure 1-10 As shown, a brush roller shaft head sealed waterproof internal circulation structure includes: a brush roller assembly 10, a spray assembly 20, a water bucket 30, a water guide groove 31, and a bracket 40. The brush roller assembly 10 includes: a brush roller 11, a clamping plate 12, a sealing ring 13 and a support seat 14. The two ends of the brush roller 11 are fixed to the bracket 40 through the support seat 14. The spray assembly 20 is fixed above the brush roller 11. At least two clamping plates 12 are respectively sleeved on the shaft heads 111 at both ends of the brush roller 11. The clamping plate 12 is fixed on the water bucket 30. Figure 8 The sealing ring 13 is a bell-mouth structure. The bell-mouths 131 of at least two sealing rings 13 are relatively sleeved on the shaft head 111 of the brush roller 11 and are located on both sides of the clamping plate 12. The sealing ring 13 and the shaft head 111 of the brush roller 11 are interference fit. Figure 6 The sealing ring 13 at the end far from the shaft head 111 is an inner sealing ring, and the bell mouth 131 of the inner sealing ring is close to the card plate 12. The sealing ring 13 at the end close to the shaft head 111 is an outer sealing ring, and there is a gap 15 between the bell mouth 131 of the outer sealing ring and the card plate 12. Fig.11 The water diversion groove 31 is fixed on both sides of the water bucket 30, and the width d2 of the water diversion groove 31 is greater than the distance d1 of the gap 15. Generally, the distance d1 of the gap 15 is 5 mm.

[0033] like Figure 5-8 The card plate 12 is a top and bottom card slot structure, with a through hole 123 in the middle, see Figure 10-11The side plates 32 at both ends of the water bucket 30 are provided with slots 321. When installing, the card plate 12 is inserted into the slot 321, and the shaft head 111 of the brush roller 11 passes through the through hole 123. Figure 6 The bell mouth 131 of the inner sealing ring is in close contact with the end face 121 of the card plate 12 , and there is a gap 15 between the bell mouth 131 of the outer sealing ring and the end face 2 122 of the card plate 12 .

[0034] like Fig.10 As shown, a plurality of drainage ports 322 are provided on the side plate 32 of the water bucket 30 , which can redirect the water in the water diversion trough 31 back into the water bucket 30 , thus realizing internal circulation drainage.

[0035] Working principle: When cleaning the glass, the spray pipe of the spray assembly 20 sprays water to the brush roller 11, the brush roller 11 rotates at high speed, and the water on the brush will move in all directions. The two ends of the brush roller 11 are fixed to the bracket 40 through the support seat 14. The shaft head 111 of the brush roller 11 is located inside the water bucket 30. If the shaft head 111 of the brush roller 11 is not sealed, the water will flow along the shaft head 111 to the parts outside the water bucket 30, which will not only cause a waste of spray water, but also affect the appearance and life of the equipment. In addition, for the acid and alkali liquid cleaning process, the acid and alkali liquid will also corrode the equipment, causing a greater safety hazard.

[0036] The brush roller shaft head sealing waterproof internal circulation structure of the present invention has at least two clamps 12 respectively sleeved on the shaft heads 111 at both ends of the brush roller 11, and the clamps 12 are inserted into the notches 321 on the side plates 32 of the water bucket 30. The shaft head 111 of the brush roller 11 rotates in the through hole 123 of the clamps 12 with a gap, and the sealing ring 13 rotates with the shaft head 111 of the brush roller 11, and the clamps 12 can block the notches 321 of the water bucket 30, playing the role of dynamic sealing. The bell mouths 131 of at least two sealing rings 13 are relatively sleeved on the shaft head 111 of the brush roller 11, and are located on both sides of the clamps 12. The sealing ring 13 is a bell mouth structure, and the bell mouth 131 of the inner sealing ring is close to the end face 121 of the clamps 12. The clamps 12 and the bell mouths 131 of the inner sealing ring can block most of the water from flowing to the outside of the water bucket 30.

[0037] Since the bell mouth 131 of the inner sealing ring is in close contact with the cardboard 12, which is equivalent to the bell mouth 131 of the inner sealing ring being in close contact with the inner wall of the side plate 32 of the water bucket 30, a small amount of water on the inner wall of the side plate 32 will flow into the shaft head 111 of the brush roller 11 through the bell mouth 131 of the inner sealing ring, and flow outward along the shaft head 111. There is a gap 15 between the bell mouth 131 of the outer sealing ring and the end face 122 of the cardboard 12. Since the width d2 of the water diversion grooves 31 on both sides of the water bucket 30 is greater than the gap 15, the water on the inner wall of the side plate 32 will flow into the shaft head 111 of the brush roller 11 through the bell mouth 131 of the inner sealing ring, and flow outward along the shaft head 111. The distance d1, the bell mouth 131 of the outer sealing ring will lead the water flowing into the shaft head 111 into the water guide groove 31 along the inclined surface of the bell mouth 131, and then flow back into the water bucket 30 through the drainage ports 322 on both sides of the water bucket 30, realizing internal circulation drainage, which can completely prevent water leakage, thereby preventing the water randomly thrown out by the high-speed rotation of the brush roller 11 from flowing along the shaft head 111 to the parts outside the water bucket 30, avoiding the waste of spray water, and also avoiding affecting the appearance and life of the equipment. When using acid and alkali liquid to clean glass, avoid acid and alkali liquid corrosion of the equipment.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
