Description

Technical Field

[0001] The utility model belongs to the field of liquid crystal glass substrate manufacturing, and particularly relates to a substrate glass fast replacement traction short roller device. Background Art

[0002] The overflow down-draw method is to allow the molten glass to flow into the overflow brick trough of the muffle furnace, so that the molten glass overflowing from the overflow trough to both sides flows down along the side walls and fuses and integrates at the tip of the overflow brick, thereby continuously forming a piece of plate glass. The glass is then clamped and pulled down by multiple sets of pulling short rollers driven by the annealing furnace motor, thereby producing qualified products that meet the process requirements.

[0003] The boss of the traction roller that clamps the glass is made of asbestos. This material has good friction when in contact with the glass and will not affect the glass. However, after a period of use, the boss of the traction roller will wear out and affect the quality of the glass. Therefore, the traction roller will be replaced after use beyond the process range.

[0004] Replacing the traction stub rollers requires downtime, and no product is produced during the replacement. Currently, replacement requires loosening the furnace door clamps, connecting rod clamps, and guide rail lock nuts, removing the traction stub rollers, and removing the nuts securing them to the base before installing the new rollers. After installation, the stub roller alignment, insertion depth, and elevation angle must be adjusted back to their original process values. This entire replacement process is lengthy, significantly impacting product output. To improve traction stub roller replacement efficiency and shorten replacement time, a design method for rapidly replacing traction stub rollers is desired. Summary of the Invention

[0005] The utility model provides a device for quickly replacing a traction short roller for substrate glass, so as to solve the technical problem that the replacement time of the traction short roller is long and the quality of the glass is affected.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A device for quickly replacing a traction short roller for a substrate glass comprises a short roller shaft cold sleeve, a bottom plate and a positioning tool, wherein the positioning tool is placed on the bottom plate, and the short roller shaft cold sleeve is clamped and fixed to the bottom plate;

[0008] The side of the short roller shaft cooling sleeve is inserted with a short roller, and the bottom of the short roller shaft cooling sleeve is provided with a slot;

[0009] The bottom plate is placed under the short roller shaft cold sleeve, and a guide rail is provided on the bottom plate. One side of the guide rail is provided with a positioning groove extending along the short side of the bottom plate;

[0010] The positioning tool is inserted into the positioning groove.

[0011] The slot is opened from the front end portion to the rear end portion of the short roller shaft cold sleeve.

[0012] The groove does not penetrate the rear end portion of the short roller shaft cold sleeve.

[0013] The guide rail is clamped and fixed to the card slot, and the shapes and sizes of the guide rail and the card slot correspond to each other.

[0014] There is a marking line engraved between the guide rail and the positioning groove on the bottom plate.

[0015] There is a gap between the positioning groove and the marking line.

[0016] A short roller slide is also provided under the bottom plate and is located at the bottom of the overall device.

[0017] The positioning tool is a "T" shaped guide rail device.

[0018] A tool handle is installed at one end of the positioning tool.

[0019] The lower end of the positioning tool corresponds to the shape and size of the positioning groove, and the lower end of the positioning tool is inserted into the positioning groove.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The utility model discloses a device for quickly replacing traction short rollers for substrate glass. The upper short roller shaft cold sleeve and the lower bottom plate are connected by guide rails and clamping grooves. The connection method is simple and easy to operate, and does not require a complicated connection process, which saves the replacement time of the short rollers to a certain extent. The clamping grooves and guide rails are relatively tight, which improves the stability of the short roller replacement device and provides a guarantee for the replacement of the traction short rollers.

[0022] Furthermore, the slot portion passes through the rear end portion of the short roller shaft cold sleeve, limiting the insertion depth of the short roller, eliminating the need to adjust the insertion depth, saving time for inserting the short roller and further saving time for replacing the short roller.

[0023] Furthermore, the clamping and fixing method between the short roller shaft cold sleeve and the base plate is in the form of a snap-on card hole. The connection method is simple and easy to operate, and the trapezoidal card slot and the inverted trapezoidal guide rail are fixed more firmly. To a certain extent, the stability of the traction short roller replacement device is improved, which provides a guarantee for the replacement of the short roller and saves replacement time.

[0024] Furthermore, by engraving a marking line on the fixed portion at the rear end of the guide rail, it is unnecessary to adjust the insertion depth of the short roller, thus saving the replacement time of the traction short roller.

[0025] Furthermore, the positioning tool is a T-shaped guide rail, which facilitates the insertion and extraction of the positioning tool, thereby effectively saving the time for replacing the short roller.

[0026] Furthermore, the tool handle installed on the positioning tool facilitates the staff to grasp the positioning tool, thereby improving the efficiency of extracting and inserting the positioning tool, and further effectively saving the time of replacing the short roller.
