Description

Technical Field

[0001] The utility model belongs to the technical field of horizontal tempering furnace glass positioning, in particular to a furnace front glass positioning device used for a horizontal tempering furnace. Background Art

[0002] Tempered glass, which increases its strength through rapid heating at high temperatures and then rapid cooling, is widely used in industries such as construction and automotive. During the glass tempering process, glass sheets typically enter a horizontal tempering furnace for heating and cooling. To ensure tempering quality, the glass must be precisely positioned before entering the furnace to ensure uniform stress distribution during heating and cooling.

[0003] In existing horizontal tempering furnace systems, glass is typically transported and positioned before entering the furnace using a conveyor. However, this traditional pre-furnace positioning method presents several issues: 1. Positioning accuracy is insufficient. Glass can easily shift during transport due to mechanical vibration or other factors, resulting in inaccurate positioning of the glass upon entering the tempering furnace, affecting heating and cooling uniformity and, in turn, tempering performance. 2. Balancing speed and positioning is difficult. High production efficiency is crucial for tempered glass, and the pre-furnace positioning system must maintain precise positioning during high-speed transport. However, excessively fast transport speeds can easily lead to positioning deviations, impacting overall production line efficiency. 3. The glass surface is susceptible to damage. Traditional positioning devices, which mechanically fix or frictionally position the glass before entering the furnace, can cause scratches or indentations on the glass surface, impacting the quality of the final product. 4. Poor adaptability to multiple glass specifications. Glass of varying sizes and shapes places varying demands on the positioning device. Existing positioning equipment often has poor adaptability to changing glass specifications, making adjustments difficult and reducing production efficiency.

[0004] Therefore, there is an urgent need for a device that can achieve high-precision positioning of the glass before it enters the horizontal tempering furnace to ensure the stability and quality of the glass during the tempering process, reduce damage to the glass surface, and adapt to the positioning requirements of various specifications of glass.

[0014] 2. It can reduce surface damage. Through the rolling contact between the positioning wheel and the glass, the device can effectively prevent the glass surface from being scratched or indented during the positioning process, protect the surface quality of the glass, and improve the appearance quality of the finished product. It is especially important for high-demand architectural and automotive glass.

[0015] 3. It can improve production efficiency.

[0020] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a glass positioning device for a horizontal tempering furnace of the present invention in conjunction with the accompanying drawings.

[0021] In order to realize automatic positioning of the glass in front of the furnace and automatic feeding of the glass into the furnace, stainless steel positioning strips are installed on both sides of the transmission roller. The positioning strips are driven by a screw pair and a hand wheel, and can be manually adjusted to suit the width of the glass to realize the left and right positioning of the glass.

[0022] like Figure 1 and Figure 2 As shown, the present embodiment provides a furnace front glass positioning device for a horizontal tempering furnace, which realizes the front and rear positioning of the glass, including a mounting plate 1 fixedly arranged on both sides of the roller frame, a mounting base 2 is arranged on the mounting plate 1, and a transverse positioning rod 3 is rotatably connected between the mounting bases 2 on both sides, and the transverse positioning rod 3 is axially slidably connected with a fixable transverse slider 4, the outer front of the transverse slider 4 is fixedly connected with a longitudinal positioning rod 5, and the longitudinal positioning rod 5 is axially slidably connected with a fixable longitudinal slider 6, a fixed shaft 7 is provided below the longitudinal slider 6, and a positioning wheel 8 is installed on the fixed shaft 7, and a connecting rod 9 is fixed to one end side of the transverse positioning rod 3, the connecting rod 9 includes a fixing portion 91 fixedly connected to the transverse positioning rod 3, a connecting head 92 extending upward is provided at the rear of the fixing portion 91, and a limiting portion 93 extending forward is provided in front of the fixing portion 91, and the limiting portion 93 can be against the mounting plate 1 to limit the maximum rotation angle of the transverse positioning rod 3, and a cylinder 10 is provided on the mounting plate 1 at the rear position of the connecting rod 9, and the piston rod end of the cylinder 10 is pivotally connected to the connecting head 92.

[0023] In this embodiment, the transverse positioning rod 3 and the longitudinal positioning rod 5 are both square rods. The two ends of the transverse positioning rod 3 are connected to the mounting base through two bearing supports. The end of the piston rod of the cylinder 10 is provided with a U-shaped ear seat, and the connecting head 92 is pivotally connected to the U-shaped ear seat through a pin shaft 11.

[0024] The transverse slider 4 is connected to the transverse positioning rod 3 via a gland and bolts, allowing it to move back and forth and left and right on the transverse positioning rod 3. Based on process requirements and glass size, the transverse slider 4 is secured in place using two bolts threaded into the center of the gland. The longitudinal slider 6 is mounted on the longitudinal positioning rod 5 and can move back and forth along the rod via internal guide grooves. It can then be secured in place on the rod 5 using bolts. The positioning wheel 8 is secured to the longitudinal slider 6 via a pin and nut.

[0025] Two sets of positioning wheels 8 are installed on the transverse positioning rod 3. When only a single positioning wheel 8 is needed for positioning before and after the glass, one set is spare and the other is used; when two positioning wheels 8 are needed for positioning before and after the glass, the two sets are used simultaneously.

[0026] When the piston rod of the cylinder 10 extends, the transverse positioning rod 3 rotates a certain angle, driving the longitudinal positioning rod 5 to descend, thereby driving the positioning wheel 8 to descend. After the glass is transferred to the positioning section, it is positioned forward and backward by the positioning wheel 8. When a piece of glass is positioned, the piston rod of the cylinder 10 retracts, the positioning wheel 8 rises, and the glass enters the heating furnace through the conveying roller. After the glass leaves the positioning section, the piston rod of the cylinder 10 extends, the positioning wheel 8 descends, and waits for the next piece of glass to be positioned, and so on.

[0027] This set of furnace front glass positioning device realizes automatic and continuous positioning of furnace front glass with high positioning accuracy and a cycle time of as fast as 4 seconds per piece, which fully meets the furnace front glass positioning requirements of tempering furnaces.
