Some embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

1 to 3, the embodiment of the present disclosure provides a glass annealing production line 10, which is configured to perform annealing on plate glass 500. It can conveniently and quickly adjust the friction between the driving wheel 130 and the conveyor belt 150 to avoid the conveyor belt 150 from tearing, breaking or slipping, thereby ensuring the material conveying efficiency.

The glass annealing production line 10 includes an annealing furnace 300, a conveyor roller 400 and a conveying device 100. The conveyor roller 400 is installed in the annealing furnace 300, and the conveyor roller 400 is configured to convey the plate glass 500 into the annealing furnace 300. The annealing furnace 300 is configured to anneal the plate glass 500. The conveyor roller 400 and the annealing furnace 300 work together to achieve continuous annealing of multiple plate glasses 500 and improve the annealing efficiency. In the actual annealing process, due to various reasons such as poor temperature control or high impurity content in the plate glass 500, the plate glass 500 located on the conveyor roller 400 in the annealing furnace 300 may explode, generating a large amount of glass fragments 600 and falling downward. In this embodiment, the material is glass fragments 600, and the conveying device 100 is installed in the annealing furnace 300 and is arranged below the conveying roller 400. The material falls onto the conveying device 100 under the action of gravity. The conveying device 100 is configured to receive the glass fragments 600 and send the glass fragments 600 out of the annealing furnace 300 to achieve the automatic cleaning and transportation function of the glass fragments 600, thereby preventing the glass fragments 600 from accumulating in the annealing furnace 300 and affecting the annealing effect.

In this embodiment, the conveying device 100 should be configured as a glass annealing production line 10, and the material conveyed by the conveying device 100 is glass fragments 600, but it is not limited to this.

The driving wheel 130 is transmission-connected to the conveyor belt 150, that is, the driving wheel 130 is connected to the driven wheel 140 through the conveyor belt 150, and the driven wheel 140 is rotatably mounted on the frame 110. The driving wheel 130 can drive the driven wheel 140 to rotate relative to the frame 110 through the conveyor belt 150 during the rotation process. The pressure regulating mechanism 160 is installed on the frame 110. The pressure regulating mechanism 160 and the driving wheel 130 are arranged opposite to each other. The conveyor belt 150 is sleeved outside the driving wheel 130 and extends along the tangent direction of the driving wheel 130, so that part of the conveyor belt 150 is arranged between the pressure regulating mechanism 160 and the driving wheel 130. The pressure regulating mechanism 160 is configured to press this part of the conveyor belt 150 on the circumferential surface of the driving wheel 130. The pressure regulating mechanism 160 can adjust the pressure of the conveyor belt 150 on the driving wheel 130, thereby adjusting the friction between the conveyor belt 150 and the driving wheel 130 to ensure that the friction between the conveyor belt 150 and the driving wheel 130 is within a reasonable range, avoiding the friction between the conveyor belt 150 and the driving wheel 130 to be too large or too small, thereby avoiding the conveyor belt 150 from being torn, broken or slipped, and ensuring the conveying efficiency of the glass fragments 600.

It should be noted that the tensioning mechanism 170 is mounted on the frame 110, and the tensioning mechanism 170 cooperates with the conveyor belt 150.

The guide roller 180 is rotatably mounted on the frame 110, and the conveyor belt 150 is arranged in close contact with the guide roller 180. The guide roller 180 is configured to guide and limit the conveyor belt 150 to prevent the conveyor belt 150 from being offset or tilted. The load-bearing beam 190 is mounted on the frame 110 and arranged below the conveyor belt 150. The load-bearing beam 190 is configured to support the conveyor belt 150 to prevent the conveyor belt 150 between the driving wheel 130 and the driven wheel 140 from falling downward under the action of gravity, thereby ensuring the stability of the conveying of the glass fragments 600.

Optionally, the support plate 200 is mounted on the frame 110, and the support plate 200 is disposed between the pressure regulating mechanism 160 and the guide roller 180, and is disposed below the conveyor belt 150. The support plate 200 is configured to lift the conveyor belt 150 to ensure that the conveyor belt 150 output from the pressure regulating mechanism 160 enters the guide roller 180 in an accurate direction, thereby ensuring the guiding accuracy of the guide roller 180. The safety limit switch 210 is mounted on the frame 110 and is electrically connected to the driving mechanism 120. The position of the safety limit switch 210 corresponds to the position of the conveyor belt 150. The safety limit switch 210 is configured to send a control signal to the driving mechanism 120 when the conveyor belt 150 is detected to be offset, so as to control the driving mechanism 120 to stop urgently.

In this embodiment, please refer to FIG. 4 , the pressure regulating mechanism 160 includes a driving assembly 161 and a pressure regulating roller 162. The driving assembly 161 is mounted on the frame 110 and is in transmission connection with the pressure regulating roller 162. The driving assembly 161 is configured to drive the pressure regulating roller 162 to move. Specifically, the pressure regulating roller 162 is arranged in parallel with the driving wheel 130, and the conveyor belt 150 is arranged in close contact with the pressure regulating roller 162, that is, the conveyor belt 150 is arranged between the pressure regulating roller 162 and the driving wheel 130. The driving assembly 161 is configured to drive the pressure regulating roller 162 to approach or move away from the driving wheel 130 to adjust the pressure of the conveyor belt 150 on the driving wheel 130, thereby adjusting the friction between the conveyor belt 150 and the driving wheel 130, which is convenient and quick.

Optionally, the pressure regulating mechanism 160 further includes a rotating rod 163. The frame 110 is provided with a support shaft 111, the rotating rod 163 is sleeved outside the support shaft 111, and is rotatably connected to the support shaft 111, the rotating rod 163 can rotate relative to the support shaft 111, and the support shaft 111 can support and limit the rotating rod 163. Specifically, the support shaft 111 is provided in the middle of the rotating rod 163, one end of the rotating rod 163 is connected to the driving assembly 161, and the other end is rotatably connected to the pressure regulating roller 162, and the driving assembly 161 is configured to drive the rotating rod 163 to rotate relative to the support shaft 111, so as to drive the pressure regulating roller 162 to rotate relative to the support shaft 111, so as to make the pressure regulating roller 162 approach or move away from the driving wheel 130.

It should be noted that the rotating rod 163 is extended in the vertical direction, the driving assembly 161 is connected to the bottom end of the rotating rod 163, the pressure regulating roller 162 is rotatably connected to the top end of the rotating rod 163, and the driving assembly 161 and the driving wheel 130 are relatively arranged on both sides of the rotating rod 163. When the driving assembly 161 pulls the rotating rod 163 in the horizontal direction and in the direction away from the driving wheel 130, the rotating rod 163 rotates relative to the support shaft 111 to drive the pressure regulating roller 162 to move in the direction close to the driving wheel 130, thereby increasing the pressure of the conveyor belt 150 on the driving wheel 130, and then increasing the friction between the conveyor belt 150 and the driving wheel 130. When the driving assembly 161 pulls the rotating rod 163 in the horizontal direction and in the direction close to the driving wheel 130, the rotating rod 163 rotates relative to the support shaft 111 to drive the pressure regulating roller 162 to move in the direction away from the driving wheel 130, thereby reducing the pressure of the conveyor belt 150 on the driving wheel 130, and further reducing the friction between the conveyor belt 150 and the driving wheel 130.

In this embodiment, referring to FIG. 4 , the driving assembly 161 includes a first driving member 1611, a capstan 1612, a fixed pulley 1613, and a transmission rope 1614.

It can be understood that when the first driving member 1611 drives the capstan 1612 to rotate, the transmission rope 1614 is wound around the capstan 1612, and the length of the transmission rope 1614 outside the capstan 1612 is shortened to pull the rotating rod 163 to rotate relative to the support shaft 111, thereby causing the pressure regulating roller 162 to move toward the direction close to the driving wheel 130; when the first driving member 1611 drives the capstan 1612 to rotate in the opposite direction, the capstan 1612 loosens the transmission rope 1614, and the length of the transmission rope 1614 outside the capstan 1612 increases. At this time, the conveyor belt 150 drives the pressure regulating roller 162 to move in the direction away from the driving wheel 130 under the action of its own tension force, and causes the rotating rod 163 to rotate in the opposite direction relative to the support shaft 111 until the transmission rope 1614 outside the capstan 1612 is straightened.

In an optional embodiment, please refer to FIG. 9 , the driving assembly 161 includes a second driving member 1615, a screw rod 1616 and a nut 1617.

Specifically, the nut 1617 is threadedly matched with the screw rod 1616, the screw rod 1616 is hinged to the rotating rod 163, and the nut 1617 can drive the screw rod 1616 to move along its axial direction during the rotation process, and drive the rotating rod 163 to rotate relative to the support shaft 111.

The conveyor belt 150 is densely provided with a plurality of mesh holes 151 to reduce the weight of the entire conveyor belt 150, realize the lightweight of the conveyor belt 150, and facilitate long-distance transportation. The conveyor belt 150 with the mesh holes 151 will not affect the heat transfer in the annealing kiln 300, thereby ensuring the annealing effect.

Optionally, the width of the conveyor belt 150 ranges from 1 meter to 8 meters. The width of the conveyor belt 150 is greater than the width of the plate glass 500.
