Description

Technical Field

[0001] This utility model relates to the field of glass processing, specifically to glass coating equipment. Background Technology

[0002] During glass processing, the required properties vary depending on the application. For example, glass undergoes etching, frosting, and polishing processes. Glass etching is a technique that uses chemical or physical means to form patterns, textures, or structures on the glass surface. Chemical etching can use corrosive agents to react with the silica in the glass. The core of chemical frosting is to use a solution prepared with frosting powder and fish acid, and then immerse the glass in it to cause a chemical reaction on the glass surface, forming a uniform texture. Due to product requirements, before chemical processing, protective films need to be applied to the surfaces of the glass that do not require etching, frosting, or polishing.

[0003] In the existing technology, when applying a film to glass, the glass is placed vertically by a rotating roller, and the film roll is rotated and installed at the bottom of the equipment. At the same time, the protective film is wrapped around the rotating roller. When the rotating roller rotates, the protective film on the bottom film roll is pulled out and attached to the glass surface. However, during this process, the film roll will shake at the bottom, which will cause the protective film to roll up or become uneven. At the same time, the shaking of the film roll will cause unstable installation. Utility Model Content

[0004] The present invention aims to provide a glass coating equipment to solve the problem of film roll vibration during the film drawing process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a glass coating equipment, including a frame, a rotating shaft detachably connected to the frame, the rotating shaft being used to coaxially fix a film roll, and mounting grooves for mounting the rotating shaft being provided on both sides of the frame with upward openings, the rotating shaft rotating at the mounting grooves under the drive of the film roll, the rotating shaft being provided with a balancing part, the balancing part being used to provide a vertically downward pulling force on the rotating shaft.

[0006] The beneficial effects of this solution are as follows: In existing glass coating equipment, the film rolls vibrate due to installation defects when the protective film is pulled off the roll. Compared with the existing technology, the balance unit always exerts a vertical downward force on the rotating shaft, which can effectively prevent the rotating shaft from vibrating. In addition, the rotating shaft can be detachably connected to the frame, and several film rolls can be installed on several rotating shafts. After the film roll is pulled out, it can be quickly replaced, improving coating efficiency.

[0007] Furthermore, the balancing part includes a wheel fixed to the rotating shaft, the wheel and the rotating shaft are coaxially arranged, a balancing component is vertically suspended at the bottom of the wheel, a U-shaped flexible component is fixed at the top of the balancing component, and a balancing gap is opened around the wheel for the flexible component to be hung.

[0008] The beneficial effects of this scheme are as follows: the wheel hangs the balance component through the balance gap and the flexible component. When the shaft rotates, the flexible component is located within the balance gap. Therefore, the wheel and the flexible component rotate relative to each other. Under the gravity of the balance component, the flexible component always has tension, which can ensure the purpose of the wheel and the flexible component rotating relative to each other, thereby ensuring that the balance component is set vertically downward.

[0009] Furthermore, the balancing components are symmetrically arranged on both sides of the rotating shaft.

[0010] Furthermore, the wheel is radially fixed to the shaft by bolts.

[0011] Furthermore, the mounting groove has a V-shaped opening, and a circular rotating groove for the rotating shaft to rotate is provided at the bottom of the mounting groove. The two sides of the mounting groove are respectively set as a vertical surface and an inclined surface, and the film roll is pulled in the same direction as the vertical surface.

[0012] The beneficial effects of this solution are as follows: by setting the two sides of the mounting groove as a vertical surface and an inclined surface respectively, if the protective film on the film roll is pulled out in the same direction as the inclined surface, the film roll will drive the shaft to rotate on the inclined surface. At this time, due to the friction between the shaft and the inclined surface, the shaft will roll upward along the inclined surface and roll out of the mounting groove. Therefore, the design of the mounting groove in this solution can prevent this phenomenon and ensure the stability of the shaft during rotation.

[0013] Furthermore, there are several rotating shafts and mounting slots, and the film roll is detachably connected to the rotating shaft.

[0014] The beneficial effects of this solution are: several rotating shafts are fitted with film rolls for backup, which can improve the efficiency of glass coating.

[0015] Furthermore, a connecting sleeve for mounting the film roll is fitted on the outer ring of the rotating shaft, and the connecting sleeve and the rotating shaft are also radially fixedly connected by bolts.

[0016] Furthermore, the outer ring of the connecting cylinder is used for supplying the film roll sleeve.

[0017] Furthermore, both ends of the connecting cylinder are fitted with cones, which are connected to the connecting cylinder by an interference fit.

[0018] The beneficial effects of this solution are as follows: by setting a cone, the conical surface of the cone is tangent to the inner ring of the film roll, and as the cones are installed facing each other, the conical surface of the cone gradually makes an interference fit with the inner ring of the film roll. Therefore, it can ensure the connection stability of the film roll installed on the rotating shaft, prevent the film roll from slipping on the connecting cylinder when drawing the film, and thus ensure the consistency between the rotation of the film roll and the rotation of the rotating shaft.

[0019] Furthermore, the frame is fixed with a mounting plate, the mounting groove is opened on the mounting plate, the outer ring of the rotating shaft is also fitted with a positioning ring, the positioning ring is also radially fixed to the rotating shaft by bolts, and the positioning plate is located between the positioning ring and the wheel.

[0020] The beneficial effects of this solution are as follows: by setting a positioning ring, which cooperates with the wheel and limits the mounting plate between them, the axial direction of the rotating shaft can be limited, thereby improving the accuracy of film coating.

[0028] The following detailed description illustrates the specific implementation method:

[0029] The reference numerals in the accompanying drawings include: frame 1, mounting plate 11, mounting groove 12, rotating groove 121, rotating shaft 2, wheel 21, balance gap 211, weight 22, flexible part 23, positioning ring 24, film winding tube 3, connecting tube 4, cone tube 41.

[0030] Example

[0031] The basic implementation examples are as follows: Figure 1-7 As shown, Figures 1-4The glass coating equipment shown includes a frame 1. Mounting plates 11 are symmetrically welded to both sides of the frame 1. Mounting plates 11 have upward-opening mounting grooves 12. The mounting grooves 12 are V-shaped. The front and rear sides of the mounting grooves 12 are respectively set as vertical and inclined surfaces. The mounting grooves 12 also include a circular rotating groove 121 opened at the bottom. The two sides of the rotating groove 121 are connected to the vertical and inclined surfaces respectively. That is, the top of the rotating groove 121 is set through the vertical and inclined surfaces. Several sets of symmetrical mounting plates 11 are provided on the frame 1, and several sets of mounting plates 11 are provided with mounting grooves 12. The frame 1 is detachably connected to a rotating shaft 2 through the mounting grooves 12. The rotating shaft 2 is inserted into the rotating grooves 121 to realize the rotational connection between the rotating shaft 2 and the frame 1. Positioning rings 24 and wheel disks 21 are respectively sleeved on both sides of the mounting plates 11 at both ends of the rotating shaft 2. The positioning rings 24 are located on the inner side of both ends, and the wheel disks 21 are located on the outer side of both ends.

[0032] like Figures 1-2 As shown, both the positioning disc and the wheel 21 are coaxially arranged with the rotating shaft 2. The positioning disc is radially threaded with bolts, which pass through the positioning ring 24 and abut against the rotating shaft 2, thereby fixing the positioning ring 24 onto the rotating shaft 2. The wheel 21 is hollow and is sleeved on the rotating shaft 2. The wheel 21 is located on the side of the mounting plate 11 away from the positioning ring 24. The wheel 21 is designed like a pulley and has a balance gap 211 in the middle. The balance gap 211 is a hollow ring in the middle of the wheel 21 and is coaxial with the rotating shaft 2. A fixing ring is fixedly welded to the end of the wheel 21 away from the mounting plate 11. The fixing ring is coaxial with the rotating shaft 2 and is also threaded with bolts. The bolts on the fixing ring pass through the fixing ring and abut tightly against the rotating shaft 2, thereby fixing the wheel 21 onto the rotating shaft 2.

[0033] A balancer is suspended at the bottom of the rotating shaft 2 via a wheel 21. The balancer is a weight 22. A connecting rod is fixed to the top of the weight 22. A connecting plate is fixed to the top of the connecting rod. A flexible component 23 is fixed to the top of the connecting plate. Both the front and rear sections of the flexible component 23 are connected to the connecting plate, thus forming a U-shape. The flexible component 23 is made of wear-resistant steel. The flexible component 23 is hung on the wheel 21 via a balance gap 211.

[0034] like Figure 7As shown, a connecting cylinder 4 is sleeved on the rotating shaft 2. The connecting cylinder 4 is coaxially arranged with the rotating shaft 2 and is also threaded with bolts. The bolts on the connecting cylinder 4 pass through the connecting cylinder 4 and abut against the rotating shaft 2, thereby fixing the connecting cylinder 4 on the rotating shaft 2. The outer ring of the connecting cylinder 4 is used to sleeve the film roll 3. The two ends of the connecting cylinder 4 are symmetrically sleeved with cones 41. The inner ring of the cone 41 and the outer ring of the connecting cylinder 4 are interference fit. In addition, when the connecting cylinder 4 and the rotating shaft 2 are fixedly installed by bolts, the side of the bolt will abut tightly against the base of the cone 41. This not only fixes the connecting cylinder 4 on the rotating shaft 2, but also limits the position of the cone 41.

[0035] The specific implementation process is as follows: Before film covering, firstly, the film roll 3 is sleeved on the outer ring of the connecting tube 4, and then the cone tube 41 is sleeved on both ends of the connecting tube 4. The conical surface of the cone tube 41 is embedded in the gap between the outer ring of the connecting tube 4 and the inner ring of the film roll 3. As the two cone tubes 41 move towards each other and are fixed at both ends of the connecting tube 4, the conical surface of the cone tube 41 gradually makes an interference fit with the inner ring of the film roll 3, thereby initially fixing the film roll 3 on the connecting tube 4. This is repeated several times to connect the film roll 3 of the towing rod assembly to the connecting tube 4 in this way. Then, the connecting tube 4 with the film roll 3 sleeved on it is sleeved on the rotating shaft 2, and it is fixedly connected to the rotating shaft 2 by the bolts connected to the connecting tube 4. At this time, the bolts on the connecting tube 4 are tightly abutted against the end of the cone tube 41, thereby fixing the film roll 3 on the rotating shaft 2. The above operation is repeated to connect several sets of connecting tubes 4 with the film roll 3 sleeved on them to the rotating shaft 2 in sequence and place them in the mounting groove 12 for later use.

[0036] A positioning ring 24 and a wheel 21 are fitted onto the rotating shaft 2, and a mounting plate 11 is placed between them to axially limit the rotating shaft 2. The protective film on the film roll 3 is wound around the rotating roller, and the rotating roller rotates to extract the protective film. During the extraction process, the film roll 3 drives the connecting cylinder 4 to rotate. Since the connecting cylinder 4 and the rotating shaft 2 are fixedly connected, the rotating shaft 2 also begins to rotate. At the same time, the wheel 21 rotates together with the rotating shaft 2. When the wheel 21 rotates, the flexible part 23 located in the balance gap 211 rubs against the wheel 21. The weight 22 is always vertically downward under the action of the flexible part 23, so that the rotating shaft 2 is always subjected to a vertically downward force, thereby preventing the rotating shaft 2 from shaking.
