Description

Technical Field

[0001] This utility model relates to the field of glass coating machine technology, specifically a three-servo lifting device for a coating machine. Background Technology

[0002] A glass coating machine is a device used to coat one or more functional thin films onto the surface of a glass substrate. Different coatings impart specific properties to the glass, such as low emissivity, high reflectivity, scratch resistance, and abrasion resistance. There are many types of glass coating machines, each with different operating principles. Among them, the roller coating machine uses a coating roller to apply the coating agent to complete the coating process. It has a simple structure, relatively low cost, and is widely used.

[0003] Existing roller-type coating machines transport glass substrates via conveyor rollers, spray coating agents onto the substrates or coating rollers, and then complete the coating process through roller pressing, UV curing, and pressure roller pressing. The height of the coating rollers and pressure rollers is adjustable to accommodate glass substrates of varying thicknesses. The drive shaft of the roller assembly is connected to a drive motor via a coupling to accommodate rotational drive before and after height adjustment. However, existing coating machines use separate servo motors to drive the overall lifting and lowering of the coating rollers and pressure rollers. While the pressure rollers are rigid and the coating rollers are flexible, they can deform and shrink during use, whereas the pressure rollers remain flexible. Furthermore, the thickness and hardness of the coating agent differ at corresponding positions on the coating rollers and pressure rollers. The integrated lifting and lowering method for the coating rollers and pressure rollers prevents flexible adjustment based on actual conditions during use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a three-servo lifting device for a coating machine, which solves the problem that existing coating machines, which use a single servo motor to drive the overall lifting of the coating roller and pressure roller, cannot be flexibly adjusted individually according to actual needs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A three-servo lifting device for a coating machine includes a coating frame, on which a conveying roller for conveying glass substrates is installed. The coating frame is provided with a pressure roller, a coating adhesive roller, and a texture-removing roller located above the glass substrates. A lifting motor is installed on one side of the coating frame corresponding to the position of the pressure roller, and lifting motors are installed on both sides of the coating frame corresponding to the positions of the coating adhesive roller and the texture-removing roller.

[0007] The pressure roller is equipped with a bearing seat one at both ends, and the coating roller and the wrinkle-removing roller are equipped with bearing seat two at both ends. The bearing seat one and bearing seat two are respectively connected to four support plates provided on the coating frame. The support plates are vertically slidably connected to the coating frame through a sliding guide assembly.

[0008] The inner walls of the coating machine frame are vertically rotatably connected to the four support plates on both sides. The lifting rods are threadedly connected to the threaded connecting seats fixed to the bottom of the support plates through the threaded grooves on the upper surface. A driven bevel gear is installed at the lower end of the lifting rods.

[0009] The lower ends of the output shafts of both the first and second lifting motors are equipped with active bevel gears. A long, rotatable transmission shaft is horizontally mounted on the coating frame at the position of the active bevel gear below the first lifting motor. Transmission bevel gears that mesh with the active and driven bevel gears are mounted on the transmission shaft. A short, rotatable transmission shaft is horizontally mounted on the coating frame at the position of the two active bevel gears below the two second lifting motors. Transmission bevel gears that mesh with the active and driven bevel gears are mounted at both ends of the transmission shaft.

[0010] Preferably, both the first lifting motor and the second lifting motor are high-precision servo motors.

[0011] Preferably, the second bearing includes a rotating bearing disposed at one end of the coating roller and the texture-removing roller, and a sliding bearing disposed at the other end. The rotating bearing is fixedly mounted on the support plate, and the sliding bearing is hingedly mounted on the support plate via a hinge seat. The hinge axis of the hinge seat is perpendicular to the opposite plane of the coating roller and the texture-removing roller.

[0012] Preferably, the sliding guide assembly includes a guide rod vertically fixed below the support plate and slidably connected to the side of the coating frame, and a positioning slide block fixed to the side of the coating frame and slidably engaged with the surface of the guide rod.

[0013] Preferably, the sliding guide components are symmetrically arranged on the front and back sides of the first and second drive shafts, respectively, and the first and second lifting motors are fixedly mounted on the fixed frame on the side of the coating machine frame, with the guide slide rod vertically penetrating the fixed frame.

[0014] Preferably, the bottom of the fixed frame is respectively fixed with a sliding sleeve retainer that is movably sleeved on the output shaft surface of the first and second lifting motors for maintaining positioning.

[0015] Preferably, the two sets of lifting rods and driven bevel gears below the pressure roller are symmetrically arranged on the left and right, and the spiral direction of the threaded grooves on the two lifting rods below the pressure roller is consistent, and the two transmission bevel gears corresponding to the driven bevel gears below the pressure roller are located on the same side of the corresponding driven bevel gears.

[0016] Preferably, the two sets of lifting motors, driving bevel gears, lifting rods, driven bevel gears, and transmission bevel gears corresponding to the coating roller are symmetrically arranged on the left and right, and the spiral directions of the threaded grooves on the two lifting rods below the coating roller are consistent.

[0017] Preferably, a positioning shaft seat is fixed on the inner wall of the coating frame, and the lifting rod is rotatably connected to the positioning shaft seat.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This utility model sets up one lifting motor to drive the pressure roller to adjust the height, and two other lifting motors to drive the coating roller to adjust the height. The height adjustment of the pressure roller and the coating roller can be controlled independently. According to the actual situation, the gap of glass substrates of different thicknesses can be compensated, so that the rolling and coating effect is better, the product quality is improved, and the problem of existing coating machines that use a single servo motor to drive the overall lifting of the coating roller and the pressure roller cannot be adjusted flexibly according to actual needs is solved.

[0020] (2) The coating roller of this utility model is equipped with a lifting motor at each end to adjust the height of the two ends of the coating roller independently. One end of the coating roller is installed through a sliding shaft seat and a hinge seat to adapt to the angle difference caused by the independent adjustment of the height of the two ends. The independent adjustment of the height of the two ends changes the pressure between the two ends and the glass substrate, eliminating the "ghosting" defect of the glass substrate caused by the traditional fixed pressure and fixed speed. Independent adjustment can disrupt the fixed cycle of "ghosting" and eliminate such defects. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-3 As shown, this utility model provides a technical solution: a three-servo lifting device for a coating machine, including a coating machine frame 1, a conveying roller 7 for conveying glass substrate 8 installed on the coating machine frame 1, a pressure roller 2, a coating adhesive roller 4 and a texture-removing roller 3 located above the glass substrate 8, a lifting motor 5 installed on one side of the coating machine frame 1 corresponding to the position of the pressure roller 2, and lifting motors 6 installed on both sides of the coating machine frame 1 corresponding to the positions of the coating adhesive roller 4 and the texture-removing roller 3. The glass substrate 8 is conveyed from back to front. The roller group cover and ultraviolet lamp of the coating machine are not shown in the figure. The structural components added in this utility model are misaligned with the inherent transmission groups of the conveying roller 7, the pressure roller 7, the coating adhesive roller 4 and the texture-removing roller 3 to avoid hindering the normal operation of the equipment.

[0027] Both the lifting motor 5 and the lifting motor 6 are high-precision servo motors. The lifting motor 5 and the lifting motor 6 are respectively fixedly installed on the fixing bracket 21 fixed on the side of the coating machine frame 1. In this utility model, the lifting motor 5 and the lifting motor 6 are servo motors that are commonly used in the market and are familiar to those skilled in the art. The lifting motor 5 and the lifting motor 6 can be installed and wired according to the instruction manual of the purchased servo motor model. No special circuit design is required. Servo motors are widely used in existing equipment. Their control system and circuit are not part of the technical features of this patent and will not be described here.

[0028] The pressure roller 2 is equipped with bearing seat 9 at both ends, and the coating roller 4 and the anti-wrinkle roller 3 are equipped with bearing seat 10 at both ends. The bearing seat 10 includes a rotating bearing seat 1001 at one end of the coating roller 4 and the anti-wrinkle roller 3 and a sliding bearing seat 1002 at the other end. The rotating bearing seat 1001 is fixedly installed on the support plate 11, and the sliding bearing seat 1002 is hinged to the support plate 11 through the hinge seat 1003. The hinge axis of the hinge seat 1003 is perpendicular to the coating roller 4 and the anti-wrinkle roller 3. One end of the coating roller 4 is installed through the sliding bearing seat 1002 and the hinge seat 1003 to adapt to the angle difference problem caused by the independent adjustment of the height at both ends. The independent adjustment of the height at both ends changes the pressure between the two ends and the glass substrate 8, eliminating the "ghosting" defect of the glass substrate 8 caused by the traditional fixed pressure and fixed speed. Independent adjustment can disrupt the fixed cycle of "ghosting" and eliminate such defects.

[0029] Shaft seat 1 9 and shaft seat 2 10 are respectively connected to four support plates 11 provided on the coating frame 1. The support plates 11 are vertically slidably connected to the coating frame 1 through the sliding guide assembly 12. The sliding guide assembly 12 includes a guide slide rod 1201 vertically fixed below the support plate 11 and slidably connected to the side of the coating frame 1, and a positioning slide seat 1202 fixed to the side of the coating frame 1 and slidably engaged with the surface of the guide slide rod 1201. The guide slide rod 1201 vertically penetrates the fixing frame 21. The sliding guide assembly 12 is symmetrically arranged on the front and back of the drive shaft 1 17 and the drive shaft 2 19 respectively.

[0030] Lifting rods 13 are vertically rotatably connected to the four support plates 11 on both sides of the inner wall of the coating frame 1. A positioning shaft seat 23 is fixed on the inner wall of the coating frame 1. The lifting rods 13 are rotatably connected to the positioning shaft seat 23. The lifting rods 13 are threadedly connected to the threaded connecting seat 14 fixedly connected to the bottom of the support plate 11 through the threaded groove on the upper surface. A driven bevel gear 15 is installed at the lower end of the lifting rods 13.

[0031] A long, rotatable drive shaft 17 is horizontally installed at the position of the active bevel gear 16 below the lifting motor 5 on the coating frame 1. A drive bevel gear 18 that meshes with the active bevel gear 16 and the driven bevel gear 15 is installed on the drive shaft 17. A short, rotatable drive shaft 19 is horizontally installed at the position of the two active bevel gears 16 below the two lifting motors 6 on the coating frame 1. A drive bevel gear 20 that meshes with the active bevel gear 16 and the driven bevel gear 15 is installed at both ends of the drive shaft 19.

[0032] The two sets of lifting rods 13 and driven bevel gears 15 below the pressure roller 2 are symmetrically arranged on the left and right sides, and the spiral direction of the thread grooves on the two lifting rods 13 below the pressure roller 2 is consistent. The two transmission bevel gears 18 corresponding to the driven bevel gears 15 below the pressure roller 2 are located on the same side of the corresponding driven bevel gears 15, so that the lifting drive on both sides is consistent and jamming is avoided.

[0033] The two sets of lifting motors 6, driving bevel gear 16, lifting rod 13, driven bevel gear 15 and transmission bevel gear 20 corresponding to the coating roller 4 are symmetrically arranged on the left and right, and the spiral direction of the threaded grooves on the two lifting rods 13 below the coating roller 4 is consistent. As a component, it has high versatility, which makes the manufacturing cost low and the installation convenient.

[0034] The lower ends of the output shafts of lifting motor 5 and lifting motor 6 are respectively equipped with driving bevel gears 16. The bottom of the fixing frame 21 is respectively fixed with sliding sleeve retainers 22 that are movably sleeved on the output shaft surfaces of lifting motor 5 and lifting motor 6 for positioning. Gearbox housings can be fixedly installed on the sliding sleeve retainers 22 at positions corresponding to the ends of transmission shaft 17 and transmission shaft 29 to maintain stable meshing transmission between driving bevel gear 16 and transmission bevel gear 18 and transmission bevel gear 20, as well as installation stability.

[0035] Working principle:

[0036] The lifting motor 5 drives the active bevel gear 16 to rotate, and through the transmission shaft 17 and the transmission bevel gear 18, it synchronously drives the two sets of driven bevel gears 15 and their corresponding lifting rods 13 to rotate in the same direction. Through the threaded connection seat 14, it drives the support plate 11 and the pressure roller 2 above it to move up or down to adjust the height.

[0037] The second lifting motor 6 drives the active bevel gear 16 to rotate, which in turn drives the driven bevel gear 15 and its corresponding lifting rod 13 to rotate via the second transmission shaft 19 and the second transmission bevel gear 20. The threaded connection seat 14 drives the support plate 11 and the coating roller 4 and the texture removal roller 3 above it to move up or down to adjust the height. The two lifting motors 6 can be driven separately, so the two ends of the coating roller 4 can be adjusted to be at different heights. One end of the coating roller 4 is installed through the sliding shaft seat 1002 and the hinge seat 1003 to accommodate the angle difference caused by the individual adjustment of the height at both ends.

[0038] In this invention, all components are regularly inspected and maintained according to actual production conditions, and all vulnerable parts are replaced during maintenance according to wear and tear and usage time to ensure normal operation.
