A production apparatus for bent tempered glass according to an embodiment of the present invention will be described below with reference to fig. 1 to 14, including a processing module 1 and a lifting module 3 provided to a heating hob;

the processing module 1 comprises a forming section 11, the forming section 11 is provided with a plurality of upper forming roll shafts 111 and lower forming roll shafts 112, and the upper forming roll shafts 111 and the lower forming roll shafts 112 are arranged in a one-to-one up-and-down correspondence manner;

the upper forming roller shaft 111 and the lower forming roller shaft 112 each include a shaft body 1111 and a forming wheel 1112, the forming wheel 1112 being provided at one end of the shaft body 1111;

each pair of the forming wheel 1112 of the upper forming roller shaft 111 and the forming wheel 1112 of the lower forming roller shaft 112 which are arranged up and down are in a circular truncated cone structure with complementary inclination angles b and a, and the inclination angle a of the forming wheel 1112 of the lower forming roller shaft 112 is gradually increased from the feeding direction to the discharging direction;

the lifting module 3 comprises a lifting unit 32, which lifting unit 32 is adapted to lift all of the upper forming roll shafts 111.

The heated and softened glass sequentially passes through the forming wheel 1112 of the lower forming roller shaft 112 with the gradually increased inclination angle of the production equipment for bending the toughened glass, and is positioned by the forming wheel 1112 of the upper forming roller shaft 111 which is complementary with the inclination angle of the forming wheel 1112 of the lower forming roller shaft 112, so that the edge of the glass is gradually bent, a preset bending angle is finally formed, and the working hour for forming the bent glass is greatly reduced. The production equipment for the bent toughened glass can meet the requirements of glass with different thicknesses by adjusting the height of the upper forming roll shaft 111 through the lifting unit 32, does not need to replace parts when producing glass with different thicknesses, and therefore improves the production efficiency and reduces the production cost.

As shown in fig. 2 to 4, the inclination angle a is an angle at which a ray formed by extending one end of the forming wheel 1112 of the lower forming roller shaft 112 connected to the shaft body 1111 toward the other end is inclined upward, and the inclination angle b is an angle at which a ray formed by extending one end of the forming wheel 1112 of the upper forming roller shaft 111 connected to the shaft body 1111 toward the other end is inclined upward. During processing, glass enters from a feed inlet of the heating furnace, the lower forming roll shaft 112 drives the glass to advance, and the glass is heated by a heating wire in the heating furnace while advancing so as to soften the glass. Then, the edge of the glass is bent in accordance with the inclination of the forming wheel 1112 of the lower forming roller shaft 112, and the glass is held at a predetermined bend angle by the positioning of the forming wheel 1112 of the upper forming roller shaft 111. As the inclination angle a of the forming wheel 1112 of the lower forming roller shaft 112 is increased, the glass bend angle is increased to finally reach a predetermined bend angle. Compared with the equipment for cooling and bending glass after the mold is shaped, the production equipment for bending the toughened glass can bend the glass without a shaping link because the bending angle of the glass is gradually finely adjusted, so that the glass can reach a preset bending angle, the processing time is shortened, and the efficiency is improved.

When processing glass of different thickness, hoisting unit 32 drives all simultaneously go up the action of shaping roller 111, makes go up shaping roller 111 and make elevating movement in vertical direction to adjust go up the interval of shaping roller 111 and lower shaping roller 112, make the interval accord with glass's thickness. In addition, when the glass is unexpectedly broken in the process of processing, the upper forming roller shaft 111 is lifted by the lifting unit 32, and the glass fragments in the heating furnace can be conveniently cleaned.

In some embodiments, the forming wheel 1112 includes a first core 1113 and a forming skewed roll surface 1115 wrapped around the exterior of the first core 1113, the first core 1113 being removably coupled to the shaft body 1111;

the axle body 1111 includes second axle core 1114 and wraps up in the outside shaping flat roll face 1116 of second axle core 1114, first axle core 1113 and second axle core 1114 can dismantle the connection, shaping flat roll face 1116 is the cylinder structure, the diameter of shaping flat roll face 1116 equals the diameter of the one end that the oblique roll face 1115 of shaping and axle body 1111 are connected.

The glass can be machined to different bend angles by simply replacing the forming wheel 1112. The forming wheel 1112 is easier and faster to replace than the entire roll shaft.

When the diameter of the forming flat roll surface 1116 is equal to the diameter of the end of the bottom surface of the forming inclined roll surface 1115, which is connected with the shaft body 1111, no protrusion is formed at the joint of the forming flat roll surface 1116 and the forming inclined roll surface 1115, but the glass is smooth in transition surface, and no protrusion or jam is formed when the glass passes through the glass, so that the glass can be smoothly conveyed.

The forming flat surface 1116 of the lower forming roll shaft 112 is used for transporting glass, and the forming flat surface 1116 of the upper forming roll shaft 111 is used for pressing the glass positioned on the lower forming roll shaft 112, so that the thickness of each position of the processed glass is the same. During operation, the lower forming roll shaft 112 rotates around the axis of the lower forming roll shaft 112, the forming flat roll surface 1116 of the lower forming roll shaft 112 also rotates along with the lower forming roll shaft, and the glass is conveyed forwards, so that the upper forming roll shaft 111 also rotates at the same angular speed, and the situation that the patterned glass is scraped due to the fact that the angular speeds of the upper forming roll shaft 111 and the lower forming roll shaft 112 are different is avoided.

For example, the tolerance of the inclination angle of the forming wheel 1112 of the adjacent two lower forming roller shafts 112 is a fixed value.

That is, the difference between the inclination angles of the forming wheels 1112 of every two adjacent lower forming roll shafts 112 is a fixed value, and an equal difference series is formed, so that the above structure can bend the glass at a fixed change rate, and when the glass is transited from one lower forming roll shaft 112 to the next lower forming roll shaft 112, the bent part will not crack due to sudden over-large or sudden over-small change rate of the inclination angle, thereby improving the quality of glass forming.

the stabilizing section 13 is provided with a plurality of upper stabilizing roller shafts 131 and lower stabilizing roller shafts 132, and the upper stabilizing roller shafts 131 and the lower stabilizing roller shafts 132 are used for keeping the bending angle of the glass at a fixed angle.

The fixed section 12 is used for guiding glass to enter the forming section 11 and avoiding glass deviation, and the fixed section 12 and the forming section 11 have no height difference due to the structure, so that the glass can be transported more stably.

Since the edge of the glass is gradually bent during the transportation of the glass, when the edge at the front end of the glass is bent to a predetermined bend angle, the edge at the rear end of the glass does not reach the predetermined bend angle, and at this time, the stabilizing section 13 can keep the portion having reached the predetermined bend angle at the forming angle, and wait for the edge at the rear end to be bent until the edge of the whole glass is bent to the predetermined bend angle. As shown in fig. 10, the right end is the tip. The structure of the upper stabilizer roller shaft 131 is identical to that of the upper mold roller shaft 111 positioned at the end, and the structure of the lower stabilizer roller shaft 132 is identical to that of the lower mold roller shaft 112 positioned at the end.

During operation, the lower driving wheel 211 rotates, the lower driving wheel 211 drives the lower driven wheel 212 to rotate, the lower driven wheel 212 drives the driving shaft 22 to rotate, so that all the lower driving wheels 213 sleeved outside the driving shaft 22 rotate, and each lower driving wheel 213 drives the corresponding roller shaft in the lower roller shaft group 14 to rotate, thereby achieving synchronous rotation. The lower drive pulley 211 is driven by a lower drive mechanism 21, and the lower drive mechanism 21 is preferably a motor.

Specifically, as shown in fig. 7 to 9, all of the upper fixed roller shaft 121, the upper forming roller shaft 111, and the upper stabilizer roller shaft 131 constitute the upper roller shaft group 15;
