[0002] In the traditional glass manufacturing process using the calendering process, when the glass liquid overflows from the feed pipe and is squeezed and formed by the calendering rollers, the calendering operation technicians are usually required to assist in guiding the glass plate to the auxiliary rollers and then to the annealing furnace so that the glass plate can be continuously produced. The tool needed in the guiding process is the flat key. The reasons for not using mechanical equipment to guide the glass plate are: 1. There are many uncertain factors in the process of using equipment to guide the plate. For example, the amount of glass liquid pulled will fluctuate to a certain extent, the calendering process of different calendering equipment will be different, the sensitivity and responsiveness of the guide plate equipment are extremely high, and the space of the calendering equipment is not enough to install the guide plate equipment.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

[0019] In the embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 3 , Fig. 9 and Fig.10 A novel flat key for glass plate guide includes a flat key head 1 and a flat key rod 2. The flat key head 1 includes a double sheet 12. A contact cavity 11 is provided inside the double sheet 12. A convex block 13 is fixedly installed on one side of the double sheet 12. A contact tip 14 is fixedly connected to one side of the convex block 13. The glass plate is forked through the contact cavity 11. In this embodiment, the flat key head 1 can be Fig. 9 The method used utilizes the contact cavity 11 opened in the middle to fork the two sides of the glass plate, because compared with Figure 8Compared with the short length of the existing flat key head shown, the present application effectively widens the length of the flat key head 1 and increases the contact area with the glass plate, so that the flat key head 1 can be smoothly forked when facing a hard or smooth glass plate; In addition, please refer to Figure 3 The flat key rod 2 includes an outer rod sleeve 21 and an inner rod tube 22. The outer rod sleeve 21 is fixedly connected to the double piece 12, and the inner rod tube 22 is movably connected to the outer rod sleeve 21. The structure of the double piece 12 also enables it to cope with more uncertain situations of the glass guide plate. Also, please refer to Fig.10 , the protrusion 13 and the contact tip 14 are used for dragging the glass plate, that is, the contact tip 14 and the protrusion 13 can increase the force points between the flat key head 1 and the glass plate and make it easier to guide the glass plate into the annealing furnace, and also avoid the danger of the glass plate falling midway; Other embodiments of the present invention: Figure 1 , and also includes an adjusting bolt 4. The flat key rod 2 is arranged on one side of the flat key head 1 and can be adjusted in length. Specifically, the adjusting bolt 4 is passed through the outer rod sleeve 21 and is screwed together with the outer rod sleeve 21, and can abut against the inner rod tube 22. Therefore, the overall contraction / extension function of the equipment can be achieved by adjusting the bolt 4, so that the equipment can cope with more different guiding conditions during the transportation of the glass plate, and avoid the problem of people being burned due to not being able to touch the glass plate inside the annealing furnace.

[0020] Other embodiments of the present invention: Figure 1 , and also includes a flat key handle 3, which is a T-shaped structure and is fixedly connected to the end of the inner rod tube 22 away from the outer rod sleeve 21, so that a person can transfer the glass plate in a stable manner by holding the flat key handle 3 with both hands, so as to avoid the problem of equipment imbalance and glass plate falling due to one end of the flat key rod 2 being too heavy.

[0021] Other embodiments of the present invention: Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The outer rod sleeve 21 is fixedly connected with a traction rod 23, and the inner rod tube 22 is provided with a traction cavity 24. The traction rod 23 is adapted to the traction cavity 24. Specifically, the diameter of the traction cavity 24 is larger than the diameter of the traction rod 23. The traction cavity 24 and the traction rod 23 are in a clearance fit state. Therefore, the traction rod 23 and the traction cavity 24 can limit the contact between the outer rod sleeve 21 and the inner rod tube 22 during the mutual movement. Specifically, the collision, friction and sliding of the traction rod 23 and the traction cavity 24 make the forces at both ends of the outer rod sleeve 21 and the inner rod tube 22 relatively balanced when the outer rod sleeve 21 and the inner rod tube 22 move, so as to achieve a smooth movement effect of the outer rod sleeve 21 and the inner rod tube 22. Please refer to Figure 2 and Figure 6 A second shock-absorbing pad 26 is fixedly connected to one end of the traction rod 23, and the second shock-absorbing pad 26 is movably connected to the inner end surface of the traction cavity 24. A first shock-absorbing pad 25 is fixedly connected to the inside of the traction cavity 24, and the first shock-absorbing pad 25 is movably connected to the inner end surface of the outer rod sleeve 21. Therefore, when the outer rod sleeve 21 and the inner rod tube 22 move to the position where the traction rod 23 contacts the traction cavity 24, shock absorption and noise reduction can be performed to avoid noise problems.

[0022] Other embodiments of the present invention: Figure 4 and Figure 7 A ball anti-slip cavity 29 is provided on the side of the outer rod sleeve 21 close to the contact cavity 11, and an easy-pull ball 20 is rotatably connected inside the ball anti-slip cavity 29, and the easy-pull ball 20 is adapted to the inner rod cylinder 22, and a cylinder anti-slip groove 27 is provided in an annular array on the side of the outer rod sleeve 21 close to the flat key handle 3, and the depth of the cylinder anti-slip groove 27 away from the end of the flat key handle 3 is greater than the depth of the cylinder anti-slip groove 27 close to the end of the flat key handle 3, and a variable pressure ball 28 is movably connected inside the cylinder anti-slip groove 27, and the variable pressure ball 28 is connected to the inner rod cylinder 22. The rod barrel 22 is adapted to each other, so when the inner rod barrel 22 starts to move in the outer rod sleeve 21, the inner rod barrel 22 can be moved and pulled more smoothly through the design of the easy-to-pull ball 20 and the ball anti-escape cavity 29. However, when the inner rod barrel 22 is close to the position of being separated from the outer rod sleeve 21, the depth of the tube anti-escape groove 27 away from the end of the flat key handle 3 can be greater than the depth of the tube anti-escape groove 27 close to the end of the flat key handle 3, so that the inner rod barrel 22 can be pulled tighter and tighter, so that it has certain limiting and anti-escape functions.

[0023] The working principle of the present invention is: the present invention can reduce the defective product rate, production accidents and production costs by conveniently, quickly and effectively introducing the glass plate into the annealing furnace. The present invention has a simple structure, and the operation and plate introduction process is safe, convenient, fast and effective, which can significantly shorten the introduction time and make up for the shortcomings of insufficient skills of the rolling operator. Thereby reducing the time of subsequent production debugging, reducing the probability of production safety hazards, ensuring production safety, and improving production capacity.
