Description

Technical Field

[0001] This utility model relates to equipment and facilities in the photovoltaic glass production process, specifically to a rolling roll head oil film cleaning device. Background Technology

[0002] Solar energy, as an ideal renewable and clean energy source, is receiving increasing attention, and countries around the world are committed to the development and utilization of solar energy resources. Photovoltaic rolled glass has also experienced rapid development. The production process of photovoltaic rolled glass involves pressing molten glass in a furnace through a rolling mill, cooling it into shape, and then annealing it. The pressing is achieved by two pressure bars pressing onto the top cover of the upper rolling roll, with each pressure bar applying approximately 6500 kgf. Due to the high pressure on the rolling roll, the roll head of the rolling mill needs to be lubricated regularly to ensure stable operation. However, the added oil seeps out and first spreads to the inside of the roll head, then gradually reaches the end of the rolling roll surface, contaminating the edges of the glass sheet. This results in the production of narrower glass sheets, significantly reducing the yield rate and greatly increasing production costs.

[0003] like Figure 1 The diagram shows the calendering roll system. Molten glass is pressed by the lower calendering roll 301 and the upper calendering roll 315, and cooled into glass strips 312. These strips are then pulled into the annealing furnace in the direction of travel, as indicated by arrow 314. The pressing pressure comes from two pressure bars 316. Oil is added to the roll head through the oiling pipe 306. The oil seeps out and spreads to the inner side 302 and outer side 303 of the roll head. The waste oil at the outer side 303 of the roll head has no impact on the product. However, the oil at the inner side 302 of the roll head further diffuses towards the end of the calendering roll as the roll rotates, as seen in the contaminated oil 310 and the outer edge 311 at the end of the calendering roll. This oil further contaminates the glass strip, as seen in the contaminated glass edge 313, resulting in product waste.

[0004] The previous practice was to regularly clean the oil off the end of the calender roll surface with a cotton cloth in the early stages. However, the problem is that the oil is difficult to clean completely. In addition, the temperature is high and the environment is harsh. During the cleaning process, debris is easily splashed onto the calender roll, causing the roll to wash and resulting in greater economic losses. Utility Model Content

[0005] In order to solve the problems in the prior art, this utility model provides a calender roll head oil film cleaning device, which can effectively clean the oil film on the inside of the roll head, thereby avoiding product waste caused by the spread of the oil film.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An oil film cleaning device for calender roll head includes an oil removal claw and an oil collection box located inside the roll head. The oil collection box is located directly below the inside of the roll head. One end of the oil removal claw is a fixed end, which is fixed to the oil collection box. The other end of the oil removal claw is an oil scraping end, which rests on the inside of the roll head and makes elastic contact with it.

[0008] Preferably, the oil collection box includes an arc-shaped bottom plate and a side panel with a lower arc, both of which have an arc radius greater than the radius of the calender roll head. The arc-shaped bottom plate and the side panel are fixedly connected to form an oil collection box with an upper opening.

[0009] Preferably, the oil collection box is provided with horizontal flaps at both ends, and the horizontal flaps are provided with first fixing holes. The oil collection box is fixed to the lower part of the inner side of the roller head through the first fixing holes and the matching fixing bolts.

[0010] Preferably, the arc-shaped bottom plate and side plate are made of stainless steel.

[0011] Preferably, the bottom of the oil collection box is provided with an oil guide hole, and an oil guide pipe is connected to the oil guide hole. The oil guide pipe extends outward and connects to the oil collection tank to form an oil storage system.

[0012] Preferably, the oil guide pipe is equipped with an oil cleaning switch.

[0013] Preferably, the oil guide pipe is made of stainless steel metal hose or copper pipe, and the oil collection tank is made of stainless steel sheet.

[0014] Preferably, the oil-removing spring claw belt includes an arc-shaped segment with a certain curvature, one end of which is connected to a horizontally arranged fixed end, and the other end of which serves as an oil scraping end.

[0015] Preferably, the fixed end is provided with a second fixing hole, through which the fixed end is fixed to the oil collection box.

[0016] Preferably, the degreasing spring claw is made of stainless steel, copper, or thin galvanized iron sheet.

[0017] The beneficial effects of this utility model are:

[0018] This invention is installed at the corresponding position on the calender roll head, which can effectively clean the oil film inside the roll head, thereby avoiding product waste caused by the spread of the oil film, improving the yield rate, reducing product defects, and lowering production costs.

[0019] This invention features an oil-removing claw with a specific curvature and elasticity. Its scraping end can make elastic contact with the inner side of the calendering roll head, thus removing the oil film that has seeped into the inner side of the roll head. The oil at this point is scraped off by the scraping end before it can diffuse to the end of the calendering roll and flows into the oil collection box.

[0020] This invention can be easily implemented, which not only avoids pollution of glass sheets and strips by waste oil and reduces production losses, but also allows for the recycling and reuse of waste oil, thereby reducing the impact on the environment. Attached Figure Description

[0031] like Figures 2 to 4As shown, this embodiment provides an oil film cleaning device for calender roll head, including an oil removal claw 2 and an oil collection box 101 located inside the roll head. The oil collection box 101 is located directly below the inner side 302 of the roll head. One end of the oil removal claw 2 is a fixed end 202, which is fixed to the oil collection box 101. The other end of the oil removal claw 2 is an oil scraping end 201, which rests on the inner side 302 of the roll head and is in elastic contact with it.

[0032] In this embodiment, the oil collection box 101 includes an arc-shaped bottom plate and a side panel with a lower arc shape. The arc radius of both is greater than the radius of the calender roll head. The arc-shaped bottom plate and the side panel are welded and fixedly connected to form an oil collection box with an upper opening.

[0033] Horizontal flaps are provided at both ends of the arc-shaped bottom plate of the oil collection box 101. The horizontal flaps are provided with first fixing holes 105. The oil collection box 101 is fixed to the lower part of the inner side of the roller head through the first fixing holes 105 and the matching fixing bolts 106.

[0034] An oil guide hole 102 is provided at the bottom of the oil collection box 101, and an oil guide pipe 103 is connected to the oil guide hole 102. The oil guide pipe 103 extends outward and connects to the oil collection tank 4 to form an oil storage system 1. The oil storage system 1 can store and discharge the waste oil scraped off by the oil removal claw 2.

[0035] The oil guide pipe 103 is also equipped with an oil cleaning switch 104 for easy control.

[0036] In this embodiment, the oil removal claw 2 includes an arc-shaped segment with a certain curvature. One end of the arc-shaped segment is connected to a horizontally arranged fixed end 202, and the other end of the arc-shaped segment serves as an oil scraping end.

[0037] The fixed end 202 is provided with a second fixing hole 203. The fixing bolt 106 passes through both the second fixing hole 203 and the first fixing hole 105 to fix the fixed end of the oil removal claw 2 to the oil collection box 101.

[0038] In this embodiment, the arc-shaped bottom plate and side panels of the oil collection box 101 are made of stainless steel. The oil guide pipe 103 is made of stainless steel flexible metal hose or copper pipe, the oil collection tank 4 is made of stainless steel sheet, and the oil removal switch 104 is made of stainless steel. The oil removal spring claw 2 is made of rust-free materials such as stainless steel sheet, copper sheet, or thin galvanized iron sheet.

[0039] Taking the calender roll 301 as an example, the installation of the calender roll head oil film cleaning device is as follows:

[0040] like Figure 4As shown, the oil guide pipe 103 is connected to the oil guide hole 102 of the oil collection box 101. The connection can be achieved by means of threading, etc. An oil cleaning switch 104 is installed on the oil guide pipe 103. The oil collection box 101 is fixed to the lower part of the inner side 302 of the roller head through the first fixing hole 105 and the fixing bolt 106; the oil removal spring claw 2 is fixed through the second fixing hole 203 at the fixing end 202, and the oil scraping end 201 is placed on the inner side 302 of the roller head, and its curvature is adjusted so that it makes elastic contact with the inner side 302 of the roller head.

[0041] The oil film cleaning device for the calender roll head is arranged on the inner side of the roll head at both ends of the lower calender roll 301.

[0042] The working principle of this utility model is as follows (taking the following calendering roll as an example):

[0043] When the oil seeps out and spreads to the inner side 302 of the roller head, the oil scraper end 201 rests on the inner side 302 of the roller head and is in elastic contact. The oil at this point is scraped off by the oil scraper end 201 before it spreads to the end of the calender roll and flows into the oil collection box 101. The bottom plate of the oil collection box 101 has a downward arc-shaped structure with an oil guide hole 102 in the middle. The waste oil flows smoothly into the oil guide hole 102 and is discharged into the oil collection tank 4 through the oil guide pipe 103. When the waste oil in the oil collection tank 4 reaches a certain depth, the oil cleaning switch 104 is closed, an empty oil collection tank 4 is replaced, and the oil cleaning switch 104 is opened.

[0044] As can be seen from the above installation and usage process, this utility model can be easily implemented, which not only avoids pollution of glass plates and strips by waste oil and reduces production losses, but also allows for the recycling and reuse of waste oil, thereby reducing the impact on the environment.
