Description

Technical Field

[0001] This utility model belongs to the technical field of glass deep processing equipment, and relates to a glass coating roller frame. Background Technology

[0002] In the glass processing industry, double-sided film application is an essential process for protecting glass surfaces from scratches and contamination. Traditional methods involve mechanically applying film to side #1 (outdoor side) of the glass, then unloading the glass into wooden crates, and manually cutting and applying the electrostatic film to side #4 (indoor side). This process has the following drawbacks:

[0003] 1. High labor costs: 3-4 people are needed to complete the cutting, positioning, and film application.

[0004] 2. Unstable quality: Manual operation can easily lead to uneven film surface and residual air bubbles;

[0005] 3. Low efficiency: Multiple steps extend the production cycle.

[0006] While some automated film application equipment exists in the current technology, most are designed for single-sided film application. Double-sided film application still requires manual intervention, and the equipment is complex and costly. Therefore, there is an urgent need for a low-cost, efficient, and stable double-sided film application solution. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a glass coating roller frame that enables double-sided glass coating at a lower cost.

[0008] The objective of this utility model can be achieved through the following technical solution: A glass coating roller frame, characterized in that the roller frame includes a roller frame body; the top of the roller frame body is provided with a conveying roller track, which is composed of a plurality of conveying rollers and free rollers arranged together, and the free rollers are arranged in the middle of the conveying roller track; the roller frame body is provided with a motor that can drive each conveying roller to rotate synchronously; a first coating mechanism and a second coating mechanism are respectively provided on the roller frame body above and below the conveying roller track; the first coating mechanism includes a support and a pressure roller spanning across the conveying roller track, and a first unwinding shaft is provided on the support; rollers are rotatably connected to both ends of the pressure roller, and annular grooves are provided on the outer circumference of each roller; the support is vertically provided with limiting grooves corresponding to the annular grooves on both sides of the conveying roller track, and under the mutual limiting action of the limiting grooves and the annular grooves, the rollers can only move up and down; the second coating mechanism includes a free roller and a second unwinding shaft.

[0009] Preferably, both ends of the first unwinding shaft and the second unwinding shaft are provided with bearings. The outer rings of the bearings at both ends of the first unwinding shaft are fixedly connected to the bracket, and the inner rings of the bearings at both ends of the first unwinding shaft are sleeved on the first unwinding shaft. The outer rings of the bearings at both ends of the second unwinding shaft are fixedly connected to the roller frame body, and the inner rings of the bearings at both ends of the second unwinding shaft are sleeved on the second unwinding shaft.

[0010] The advantages of this utility model are:

[0011] 1. Simple structure and low cost: This laminating frame has a simple structure, requiring only structural modifications to the company's existing unloading roller frame, thus the cost is very low. Moreover, it can complete the laminating operation on both sides of the glass with only a few manual assistance, reducing labor costs and equipment investment.

[0012] 2. Quality Improvement: Mechanical rolling eliminates bubbles and wrinkles from manual film application, increasing the yield rate to over 99%.

[0013] 3. Efficiency optimization: Film application and conveying are carried out simultaneously, reducing the production cycle of a single piece of glass by 30%. Attached Figure Description

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, a glass coating roller frame includes a roller frame body 1; the top of the roller frame body 1 is provided with a conveyor roller track, which is composed of a plurality of conveyor rollers 11 arranged together and free rollers, and the free rollers 12 are located in the middle of the conveyor roller track; the roller frame body 1 is provided with a motor 13 that can drive each conveyor roller 11 to rotate synchronously; a first coating mechanism and a second coating mechanism are respectively provided on the roller frame body 1 above and below the conveyor roller track; the first coating mechanism includes a support 21 and a pressure roller 22 spanning across the conveyor roller track, and a first unwinding shaft 23 is provided on the support 21; rollers 24 are rotatably connected to both ends of the pressure roller 22, and annular grooves 25 are provided on the outer circumferential surface of each roller 24; a limiting groove 26 corresponding to the annular groove 25 is vertically opened on both sides of the conveyor roller track on the support 21, and under the mutual limiting action of the limiting grooves 26 and the annular grooves 25, the rollers 24 can only move up and down; the second coating mechanism includes a free roller 12 and a second unwinding shaft 3.

[0020] Working principle as follows Figure 2 As shown, this coating roller frame is located at the end of the automatic glass production line for enamel glass, coated glass, etc. The processed glass flows from the automatic production line to the conveyor roller of this roller frame. We pre-load the film roll 4 onto the first unwinding shaft 23 and the second unwinding shaft 3, and start the motor 13 to make the conveyor roller run. When the glass is conveyed to the bottom of the first coating mechanism, we pull out the film from the first unwinding shaft 23, so that the adhesive side is stuck to the edge of the upper surface of the glass, while the non-adhesive side is wrapped around the outer circumference of the pressure roller 22 and pressed by the pressure roller 22. Then, as the glass is conveyed on the conveyor roller, the coating of its upper surface is completed. In this process, under the action of the pressure roller 22's own weight, it can continuously roll the film. When the glass passes over the second coating mechanism, we can pull out the film from the second unwinding shaft 3 and make it wrap around the free roller 12 in an "S" shaped path with the adhesive side facing up. When the glass passes the free roller 12, the bottom of the glass will be automatically adhered to the film, and the film will be applied to the lower surface of the glass as the glass is conveyed on the conveyor roller. During this process, the free roller 12 can roll the film on the lower surface of the glass under the action of the glass's own gravity.

[0021] This laminating frame can apply film to both surfaces of glass. Its simple structure requires only modifications to the existing unloading roller frame, resulting in very low cost. Furthermore, it can complete the glass lamination process with minimal manual assistance, significantly improving production efficiency and reducing labor costs and equipment investment. During the lamination process, it utilizes the pressure roller 22 and the glass's own gravity to roll the applied film, ensuring a smoother adhesion and greatly reducing air bubbles left after lamination.

[0022] like Figure 1 As shown, bearings 5 ​​are provided at both ends of the first unwinding shaft 23 and the second unwinding shaft 3. The outer rings of the bearings 5 ​​at both ends of the first unwinding shaft 23 are fixedly connected to the bracket 21, and the inner rings of the bearings 5 ​​at both ends of the first unwinding shaft 23 are sleeved on the first unwinding shaft 23. The outer rings of the bearings 5 ​​at both ends of the second unwinding shaft 3 are fixedly connected to the roller frame body 1, and the inner rings of the bearings 5 ​​at both ends of the second unwinding shaft 3 are sleeved on the second unwinding shaft 3. The provision of bearings 5 ​​at both ends of the first unwinding shaft 23 and the second unwinding shaft 3 can significantly reduce the noise generated by the coating process. Furthermore, the free insertion of the first unwinding shaft 23 and the second unwinding shaft 3 into their respective bearings 5 ​​makes the installation and disassembly of the film roll 4 more convenient.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
