[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 2023118433904, filed with the Chinese Patent Office on December 28, 2023, entitled “A conveying device and a glass annealing production line,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0003] The present disclosure relates to the technical field of material conveying, and in particular to a conveying device and a glass annealing production line. Background Art

[0004] Currently, the mainstream methods of material conveying include belt drives, roller drives, and chain drives. Belt drives utilize friction between a driving pulley and a driven pulley to drive the conveyor belt, achieving material conveying. However, the friction between the driving pulley and the conveyor belt in existing belt drives is not adjustable. Excessive friction can cause the conveyor belt to become overly tight, making it prone to tearing or breaking. Excessive friction can cause the conveyor belt to slip relative to the driving pulley, impacting material conveying efficiency.

[0046] The following describes some embodiments of the present disclosure in detail with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0047] 1 to 3 , the present disclosure provides a glass annealing production line 10 configured to anneal plate glass 500. The production line can conveniently and quickly adjust the friction between the driving wheel 130 and the conveyor belt 150 to prevent the conveyor belt 150 from tearing, breaking, or slipping, thereby ensuring efficient material transportation.

[0048] The glass annealing production line 10 includes an annealing lehr 300, a conveyor roller 400, and a conveying device 100. The conveyor roller 400 is installed within the annealing lehr 300 and is configured to convey sheet glass 500 into the annealing lehr 300. The annealing lehr 300 is configured to anneal the sheet glass 500. The conveyor roller 400 and the annealing lehr 300 work together to achieve continuous annealing of multiple sheets of sheet glass 500, thereby improving annealing efficiency. During the actual annealing process, due to various reasons such as poor temperature control or a high impurity content in the sheet glass 500, the sheet glass 500 located on the conveyor roller 400 in the annealing lehr 300 may explode, generating a large amount of glass fragments 600 that fall downward. In this embodiment, the material is glass fragments 600. The conveying device 100 is installed in the annealing furnace 300 and is arranged below the conveyor 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.

[0049] 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. In other embodiments, the conveying device 100 can also convey other materials, and the application scenario of the conveying device 100 is not specifically limited.

[0050] The conveying device 100 includes a frame 110, a drive mechanism 120, a driving wheel 130, a driven wheel 140, a conveyor belt 150, a pressure regulating mechanism 160, a tensioning mechanism 170, a guide roller 180, a load-bearing beam 190, a support plate 200, and a safety limit switch 210. The drive mechanism 120 is mounted on the frame 110 and connected to the driving wheel 130. The drive mechanism 120 is configured to drive the driving wheel 130 to rotate. The driving wheel 130 is in transmission connection with the conveyor belt 150, that is, the driving wheel 130 is connected to the driven wheel 140 via the conveyor belt 150. The driven wheel 140 is rotatably mounted on the frame 110. During rotation, the driving wheel 130 can drive the driven wheel 140 to rotate relative to the frame 110 via the conveyor belt 150. 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 tangential 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 against 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 being too large or too small, thereby avoiding the conveyor belt 150 from tearing, breaking or slipping, and ensuring the conveying efficiency of the glass fragments 600.

[0051] It should be noted that the tensioning mechanism 170 is mounted on the frame 110 and cooperates with the conveyor belt 150. The tensioning mechanism 170 is configured to tighten the conveyor belt 150 to ensure that the conveyor belt 150 can rotate with the driving wheel 130 and the driven wheel 140. The guide roller 180 is rotatably mounted on the frame 110, and the conveyor belt 150 is disposed 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 deflecting or tilting. The load-bearing beam 190 is mounted on the frame 110 and disposed below the conveyor belt 150. The load-bearing beam 190 is configured to support the conveyor belt 150 to prevent the conveyor belt 150 from falling downward under the action of gravity between the driving wheel 130 and the driven wheel 140, thereby ensuring the stability of the conveying of the glass fragments 600.

[0052] Optionally, a support plate 200 is mounted on the frame 110. The support plate 200 is disposed between the pressure regulating mechanism 160 and the guide roller 180 and 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 the correct direction, thereby ensuring the guiding accuracy of the guide roller 180. A safety limit switch 210 is mounted on the frame 110 and electrically connected to the drive 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 drive mechanism 120 upon detecting that the conveyor belt 150 has deviated, thereby causing the drive mechanism 120 to stop suddenly.

[0053] In this embodiment, referring to FIG4 , the pressure regulating mechanism 160 includes a drive assembly 161 and a pressure regulating roller 162. The drive assembly 161 is mounted on the frame 110 and is in transmission connection with the pressure regulating roller 162. The drive assembly 161 is configured to drive the pressure regulating roller 162 to move. Specifically, the pressure regulating roller 162 is arranged parallel to 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 drive assembly 161 is configured to drive the pressure regulating roller 162 to move closer to or 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.

[0054] 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 drive assembly 161, and the other end is rotatably connected to the pressure regulating roller 162. The drive assembly 161 is configured to drive the rotating rod 163 to rotate relative to the support shaft 111, thereby driving the pressure regulating roller 162 to rotate relative to the support shaft 111, thereby causing the pressure regulating roller 162 to approach or move away from the driving wheel 130.

[0055] It should be noted that the rotating rod 163 extends vertically, the driving assembly 161 is connected to the bottom end of the rotating rod 163, and the pressure-regulating roller 162 is rotatably connected to the top end of the rotating rod 163. The driving assembly 161 and the driving pulley 130 are arranged on opposite sides of the rotating rod 163. When the driving assembly 161 pulls the rotating rod 163 horizontally and away from the driving pulley 130, the rotating rod 163 rotates relative to the support shaft 111, driving the pressure-regulating roller 162 toward the driving pulley 130, thereby increasing the pressure of the conveyor belt 150 on the driving pulley 130 and further increasing the friction between the conveyor belt 150 and the driving pulley 130. When the driving assembly 161 pulls the rotating rod 163 in the horizontal direction and toward 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.

[0056] In this embodiment, referring to Figure 4 , the drive assembly 161 includes a first drive member 1611, a capstan 1612, a fixed pulley 1613, and a transmission rope 1614. The first drive member 1611 is mounted on the frame 110 and connected to the capstan 1612. The first drive member 1611 is configured to rotate the capstan 1612. Specifically, the transmission rope 1614 is wound around the fixed pulley 1613. One end of the transmission rope 1614 is connected to the capstan 1612, and the other end is connected to the rotating rod 163. The fixed pulley 1613 is configured to adjust the direction of movement of the transmission rope 1614.

[0057] The first driving member 1611 is a driving motor, but is not limited thereto. In other embodiments, the first driving member 1611 may be a pneumatic motor or a hydraulic motor, and the type of the first driving member 1611 is not specifically limited.

[0058] 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, 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.

[0059] In an alternative embodiment, referring to FIG9 , the drive assembly 161 includes a second drive member 1615, a screw rod 1616, and a nut 1617. The second drive member 1615 is mounted on the frame 110 and connected to the nut 1617. The second drive member 1615 is configured to drive the nut 1617 to rotate. Specifically, the nut 1617 is threadedly engaged with the screw rod 1616, which is hingedly connected to the rotating rod 163. During rotation, the nut 1617 can drive the screw rod 1616 to move along its axial direction and drive the rotating rod 163 to rotate relative to the support shaft 111.

[0060] The second driving member 1615 is a driving motor, but is not limited thereto. In other embodiments, the second driving member 1615 may be a pneumatic motor or a hydraulic motor, and the type of the second driving member 1615 is not specifically limited.

[0061] Please continue to refer to Figures 2 and 3. It is worth noting that the conveyor belt 150 is relatively provided with a transport section 154 and a reset section 155, wherein the transport section 154 is arranged above the reset section 155 at intervals, and the transport section 154 and the reset section 155 are both located between the driving wheel 130 and the driven wheel 140. The conveyor belt 150 located in the transport section 154 can move to the reset section 155 under the driving action of the driving wheel 130 and the driven wheel 140, and the conveyor belt 150 located in the reset section 155 can move to the transport section 154 under the driving action of the driving wheel 130 and the driven wheel 140. Specifically, the conveyor belt 150 located in the transport section 154 is configured to receive the glass fragments 600 and send the glass fragments 600 out of the annealing furnace 300, and the safety limit switch 210 cooperates with the conveyor belt 150 located in the transport section 154; the conveyor belt 150 located in the reset section 155 is configured to realize the circular rotation of the conveyor belt 150, and the pressure regulating mechanism 160, the tensioning mechanism 170, the guide roller 180 and the support plate 200 all cooperate with the conveyor belt 150 located in the reset section 155.

[0062] Optionally, the load-bearing beam 190 is divided into a first load-bearing beam 193 and a second load-bearing beam 194, wherein the first load-bearing beam 193 is arranged below the transport section 154, and the first load-bearing beam 193 is configured to support the conveyor belt 150 located in the transport section 154, and the second load-bearing beam 194 is arranged below the reset section 155, and the second load-bearing beam 194 is configured to support the conveyor belt 150 located in the reset section 155.

[0063] 5 and 6 , in this embodiment, the conveyor belt 150 is a mesh belt, which is densely covered with a plurality of mesh holes 151 to reduce the weight of the entire conveyor belt 150 , thereby achieving lightweighting of the conveyor belt 150 and facilitating long-distance transportation. Furthermore, the conveyor belt 150 with the mesh holes 151 will not affect the heat transfer in the annealing furnace 300 , thereby ensuring the annealing effect.

[0064] Optionally, the width of the conveyor belt 150 ranges from 1 meter to 8 meters, and the width of the conveyor belt 150 is greater than the width of the plate glass 500. A reasonable width of the conveyor belt 150 can ensure that the glass fragments 600 falling from the conveyor roller 400 are completely received to prevent the omission of glass fragments 600.

[0065] Optionally, the mesh 151 is rectangular, the length of the mesh 151 ranges from 15 mm to 50 mm, the width of the mesh 151 ranges from 5 mm to 25 mm, and the size of the mesh 151 is smaller than the size of the glass fragments 600. Reasonable length and width of the mesh 151 can ensure the bearing effect of the glass fragments 600 and prevent the glass fragments 600 from falling through the mesh 151.

[0066] In this embodiment, the conveyor belt 150 includes a plurality of spiral buckles 152 and a plurality of connecting rods 153. The plurality of spiral buckles 152 are arranged side by side and staggered, and the connecting rod 153 is arranged to pass through two adjacent spiral buckles 152 at the same time and can rotate relative to the spiral buckles 152. That is, the two spiral buckles 152 are connected by a connecting rod 153 to prevent the two spiral buckles 152 from separating. Moreover, the two spiral buckles 152 can rotate relative to the connecting rod 153 to ensure that the conveyor belt 150 can move under the drive of the driving wheel 130 and the driven wheel 140.

[0067] Optionally, the connecting rod 153 and the spiral buckle 152 are detachably connected, and the user can select the number of the spiral buckle 152 and the connecting rod 153 according to actual conditions to adjust the length of the conveyor belt 150.

[0068] In this embodiment, the spiral buckle 152 is rectangular, i.e., the mesh 151 formed by the spiral buckle 152 is rectangular. The cross-section of the spiral buckle 152 is circular, and the diameter of the cross-section of the spiral buckle 152 is in the range of 1 mm to 4 mm. The connecting rod 153 is cylindrical, and the diameter of the connecting rod 153 is in the range of 1.5 mm to 5 mm.

[0069] It is understandable that a reasonable diameter of the circular cross section of the spiral ring buckle 152 and a diameter of the connecting rod 153 can ensure the strength and structural stability of the conveyor belt 150 and ensure the stability of conveying the glass fragments 600.

[0070] In this embodiment, the spiral ring buckle 152 and the connecting rod 153 are both made of stainless steel, but are not limited to this. In other embodiments, the spiral ring buckle 152 and the connecting rod 153 can both be made of metal materials or both be made of plastic. There is no specific limitation on the material of the spiral ring buckle 152 and the connecting rod 153.

[0071] Continuing with Figure 3 , the drive mechanism 120 includes a third drive member 121 and a gearbox 122. The gearbox 122 is mounted on the frame 110. The input end of the gearbox 122 is connected to the third drive member 121, and the output end of the gearbox 122 is connected to the driving wheel 130. The third drive member 121 is configured to output power to the gearbox 122, which is configured to increase torque, reduce rotational speed, and output power to the driving wheel 130. Specifically, the third drive member 121 utilizes variable frequency control, in conjunction with the gearbox 122, to achieve flexible adjustment of the rotational speed of the driving wheel 130, thereby adjusting the feed speed of the conveyor belt 150.

[0072] In this embodiment, the circumferential surface of the driving wheel 130 is provided with a rough layer (not shown), and the conveyor belt 150 is disposed in contact with the rough layer. The rough layer has a high coefficient of friction, which increases the friction between it and the conveyor belt 150 under the same pressure, thereby preventing the conveyor belt 150 from slipping relative to the driving wheel 130. Optionally, the diameter of the driving wheel 130 is larger than the diameter of the driven wheel 140. There are two driven wheels 140, which are spaced apart in the vertical direction. The top of the driving wheel 130 is located on the same horizontal plane as the top of the driven wheel 140 located above it, so as to ensure that the conveyor belt 150 can convey the glass fragments 600 horizontally out of the annealing furnace 300, thereby ensuring conveying efficiency.

[0073] In this embodiment, referring to FIG7 , the tensioning mechanism 170 includes a tensioning roller 171 and a counterweight 172. The frame 110 is provided with a base 113 having a guide rail 112. The guide rail 112 extends in a vertical direction. The tensioning roller 171 slidably engages with the guide rail 112 and is rotatable relative to the guide rail 112. The counterweight 172 is suspended from the tensioning roller 171. Under the action of its own weight and the weight of the counterweight 172, the tensioning roller 171 has a tendency to slide downward relative to the guide rail 112. Specifically, the conveyor belt 150 is arranged in close contact with the tensioning roller 171 and is arranged at the bottom of the tensioning roller 171. The conveyor belt 150 supports the tensioning roller 171. The weight of the tensioning roller 171 and the counterweight block 172 are all borne on the conveyor belt 150 to realize the tensioning function of the conveyor belt 150, and the conveyor belt 150 can drive the tensioning roller 171 to rotate relative to the guide rail 112 to ensure the stability of the conveyor belt 150 during the conveying process.

[0074] Optionally, referring to FIG7 , the tensioning mechanism 170 is provided with a counterweight 172. The weight of the counterweight 172 and the tensioning roller 171 are jointly borne on the conveyor belt 150 to ensure that the conveyor belt 150 is tensioned. However, the present invention is not limited to this embodiment. In other embodiments, the tensioning mechanism 170 may not be provided with the counterweight 172. In this case, only the weight of the tensioning roller 171 is borne on the conveyor belt 150. In some scenarios, this can also ensure that the conveyor belt 150 is tensioned.

[0075] Optionally, there are multiple tensioning mechanisms 170 and bases 113, and multiple guide rollers 180. Multiple tensioning mechanisms 170 and multiple guide rollers 180 are alternately arranged in sequence to ensure the tensioning and guiding effects on the conveyor belt 150, thereby optionally improving the stability of the movement of the conveyor belt 150.

[0076] Optionally, referring to Figure 10 , the tensioning mechanism 170 further includes a fourth drive member 173, and the tensioning mechanism 170 no longer includes the counterweight 172. It should be noted that the fourth drive member 173 is mounted on the base 113 and connected to the tensioning roller 171. The fourth drive member 173 is configured to drive the tensioning roller 171 to slide relative to the guide rail 112 to adjust the tensioning force of the tensioning roller 171 on the conveyor belt 150, thereby ensuring that the conveyor belt 150 is in a tensioned state.

[0077] The fourth driving member 173 is an electric cylinder, but is not limited thereto. In other embodiments, the fourth driving member 173 may be a pneumatic cylinder or a hydraulic cylinder, and the type of the fourth driving member 173 is not specifically limited.

[0078] Please refer to Figure 8. In this embodiment, the load-bearing beam 190 includes a load-bearing crossbeam 191 and a load-bearing longitudinal beam 192. The load-bearing crossbeam 191 is arranged perpendicular to the load-bearing longitudinal beam 192 and is fixedly connected to the load-bearing longitudinal beam 192. The load-bearing crossbeam 191 and the load-bearing longitudinal beam 192 work together to optionally enhance the support effect of the conveyor belt 150 and ensure the stability of the movement of the conveyor belt 150.

[0079] In this embodiment, the first driving member 1611 and the third driving member 121 are both driving motors, but are not limited to this. In other embodiments, the first driving member 1611 and the third driving member 121 can both be pneumatic motors or hydraulic motors, and there is no specific limitation on the types of the first driving member 1611 and the third driving member 121.

The pressure regulating mechanism 160 is configured to press the conveyor belt 150 against the circumference of the driving wheel 130 and adjust the friction between the conveyor belt 150 and the driving wheel 130. Compared to the prior art, the conveying device 100 provided in the present disclosure, due to the use of the driving wheel 130 connected to the driving mechanism 120 and the conveyor belt 150 disposed between the pressure regulating mechanism 160 and the driving wheel 130, can conveniently and quickly adjust the friction between the driving wheel 130 and the conveyor belt 150, thereby preventing the conveyor belt 150 from tearing, breaking, or slipping, thereby ensuring the efficient conveying of the glass fragments 600. The glass annealing production line 10 can realize automatic cleaning and transportation of the glass fragments 600, saving time and labor, and having high cleaning efficiency and good cleaning effect.
