Description

Technical Field

[0001] This invention relates to the technical field of tempering furnaces, and in particular to a hot bending tempering furnace for tempered glass. Background Technology

[0002] Hot-bent glass is designed to meet the high-quality requirements of modern architecture. Hot-bent glass is formed by heating flat glass to near its softening temperature in a hot-bending furnace and shaping it according to a pre-made mold. However, when tempering glass products in a hot-bending tempering furnace, existing hot-bending furnaces rely solely on heating and mold forming, which cannot achieve complex shapes with large changes in curvature. It is also difficult to control the curvature, resulting in the glass and mold not fitting perfectly and failing to achieve the ideal hot-bending effect.

[0003] Currently, glass products are hot-bent in a hot-bending tempering furnace and then sent to an air grid system for cooling. The upper and lower air grid systems spray room temperature air at a wind speed of 20-80 m / s. During the blowing, the air grid nozzles need to be 20-50 mm away from the glass surface (too close will cause cracking, too far will reduce cooling efficiency). However, the fixed air outlet angle of the air grid is difficult to adjust, making it difficult to cover the entire glass product with air. Because the glass products are curved arc structures, and the arc structure of the glass products also makes it difficult to adjust the blowing distance, the blowing angle and pressure distribution of the air grid cannot evenly cover the surface of the glass product. Uneven cooling will lead to uneven distribution of internal stress in the glass, which will cause the glass to crack or deform, greatly affecting the quality of the glass products and production efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a hot bending tempering furnace for tempered glass.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a hot bending tempering furnace for tempered glass, comprising a hot bending furnace body, a tempering furnace body, and a base conveyor frame, wherein the hot bending furnace body and the tempering furnace body are disposed on the top of the base conveyor frame, and a conveying friction roller is disposed on the top of the base conveyor frame; a hot bending bonding assembly for hot bending the heated glass is disposed inside the hot bending furnace body, the hot bending bonding assembly comprising a lower mold, an upper mold, and a soft capsule, the soft capsule being disposed at the bottom of the upper mold; an annular cooling assembly for cooling the hot-bent glass is disposed inside the tempering furnace body, a fan frame disposed on the annular cooling assembly for cooling the hot-bent glass; the annular cooling assembly further comprises a cooling base plate for placing the hot-bent glass, the cooling base plate causing the hot-bent glass to rotate around the fan frame for cooling;

[0006] Inside the tempering furnace, at the end furthest from the hot bending furnace, there is a horizontal cooling component that reciprocates to cool the hot-bent glass. The base fan box of the horizontal cooling component cools the bottom of the hot-bent glass back and forth. A rotating disk inside the tempering furnace drives the base fan box to reciprocate horizontally at the bottom of the cooling plate. Inside the tempering furnace, at the end furthest from the hot bending furnace, there is a unloading pushing component that pushes the cooled glass. The unloading pushing component includes a pushing box and a movable suction cup for gripping the glass.

[0007] As a preferred embodiment of the present invention, the tempering furnace body is provided with a rotating bracket whose height matches that of the conveying friction roller, and the rotating bracket is provided with a rotating support roller for conveying glass. A first lifting cylinder is fixedly installed at the bottom of the tempering furnace body by bolts, and the lower mold is fixedly installed at the top of the first lifting cylinder, and the lower mold is located at the bottom of the rotating bracket.

[0010] A rotary motor is fixedly installed on one side of the outer side of the tempering furnace body. The output end of the rotary motor is connected to a rotary shaft. First pulleys are fixedly installed at both ends of the rotary shaft. Second pulleys are fixedly installed at the end of the supporting shaft away from the fan frame. A transmission belt is connected between the second pulley and the first pulley. A movable gear is fixedly installed on the side of the rotating plate away from the fan frame. The movable gear meshes with the fixed gear. Several staggered first fans are provided at both ends of the fan frame. A battery pack that provides power to the first fans is fixedly installed at the center of the fan frame. Several strip grooves are evenly opened on the cooling base plate.

[0011] As a preferred embodiment of the present invention, the horizontal cooling assembly further includes a first bevel gear fixedly mounted on a rotating shaft. A base plate is fixedly mounted at the bottom of the tempering furnace body at the end away from the hot bending furnace body. A connecting shaft is movably connected to the top of the base plate. A second bevel gear is fixedly mounted at one end of the connecting shaft, and the second bevel gear is movably meshed with the first bevel gear. A connecting disc is fixedly mounted at the other end of the connecting shaft. An arc-shaped limiting rod is fixedly mounted on the side of the connecting disc away from the first bevel gear. An arc-shaped rotating ring is movably sleeved on the outside of the arc-shaped limiting rod.

[0012] The bottom of the tempering furnace body has connecting plates fixedly installed at both ends on the side of the connecting plate away from the first bevel gear. The top of each connecting plate is movably sleeved with a moving rod. One end of each moving rod is fixedly installed on an arc-shaped rotating ring, and the other end of each moving rod is fixedly installed with a base fan box. A second fan is fixedly installed inside each base fan box, and the second fan is movable at the bottom of the cooling base plate.

[0013] As a preferred embodiment of the present invention, the unloading pushing assembly further includes a servo motor installed inside the pushing box. The pushing box is installed on the inner top of the tempering furnace body via a connecting column. A screw is fixedly installed at the output end of the servo motor.

The movable suction cup is movable at the top of the cooling bottom plate and the conveying friction roller.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0015] 1. In this invention, the fan frame in the surrounding cooling component, in conjunction with the cooling base plate, provides circumferential heat dissipation to the hot-bent glass product. This circumferential cooling along the vertical direction of the glass product improves the uniformity of cooling and ensures that the cold air can evenly cover the entire curved glass surface, regardless of the glass's size and shape. This allows for better control of the cold air jet angle and pressure distribution, thus achieving uniform cooling of the glass surface. The flexible capsule in the hot-bending bonding component applies uniform pressure to each point without pressure marks, allowing it to better conform to the required curvature of the mold. The horizontal cooling component reciprocates by blowing air onto the bottom of the glass product, improving heat dissipation.

[0016] 2. In this invention, the liquid in the soft capsule of the hot bending bonding component has good fluidity and uniform pressure. The liquid capsule method is used to uniformly press the glass surface. The liquid has good fluidity and the pressure is uniform at each point without pressure marks. Before pressing, the glass is heated to the extreme softening state by a heating gun to facilitate shaping. The liquid capsule applies pressure to the top of the glass to make it better match the curvature requirements of the mold and improve the hot bending quality of the glass product.

[0017] 3. In this invention, the fan frame of the annular cooling component adopts a three-dimensional dynamic positioning system, which can accurately move to the bottom, top and double edge positions of the cooling base plate to achieve full-enclosed cooling of glass products. The first fan array built into the fan frame works in conjunction with the high-capacity battery pack to improve the cooling uniformity of the glass products. The fans are arranged in an oblique staggered pattern to generate superimposed vortices, which break the thermal boundary layer on the glass surface and shorten the processing time of glass products compared with traditional systems.

[0018] 4. In this invention, the arc-shaped rotating ring in the horizontal cooling component, in conjunction with the arc-shaped limiting rod, drives the moving rod on the connecting plate to reciprocate, converting the rotational motion into the precise horizontal reciprocating motion of the moving rod. The moving rod is linked to the second fan group in the base fan box, causing it to perform a horizontally adjustable reciprocating sweeping airflow along the bottom of the glass product surface. This dynamic cooling mode breaks through the limitations of the traditional fixed air field, expanding the fan coverage area to 2-3 times that of the static system. This reduces the difference in cooling rate between the edge and the center during the glass tempering process, improves the cooling effect, and enhances the uniformity of internal stress in the glass product.

[0019] 5. In this invention, the push rod, servo motor, screw and electric telescopic rod in the unloading push assembly drive the array of adaptive movable suction cups to vacuum adsorb and grasp the glass products. After grasping, the servo motor and screw drive the push block to move horizontally and smoothly transfer the glass products carried by the suction cup assembly to the base transmission frame. The polyurethane-coated conveying friction roller outputs the finished product at an adjustable speed. The positional error of the entire process is low, which improves the transportation stability of curved glass products. Attached Figure Description

[0034] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0035] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a hot bending tempering furnace for tempered glass includes a hot bending furnace body 10, a tempering furnace body 12, and a base transfer frame 13. The hot bending furnace body 10 and the tempering furnace body 12 are disposed on top of the base transfer frame 13. A conveying friction roller 14 is disposed on the top of the base transfer frame 13. A hot bending bonding assembly for hot bending the heated glass is disposed inside the hot bending furnace body 10. The hot bending bonding assembly includes a lower mold 21, an upper mold 22, and a soft capsule 20. The soft capsule 20 is disposed at the bottom of the upper mold 22.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The tempering furnace body 12 is equipped with a rotating bracket 15 that matches the height of the conveying friction roller 14. The rotating bracket 15 is equipped with a rotating roller 16 for conveying glass. The rotating roller 16 can move inside the rotating bracket 15. When the lower mold 21 is lifted, the adjacent rotating rollers 16 will be displaced to different degrees, so that the lower mold 21 drives the glass sheet on the rotating roller 16 to perform hot bending. The bottom of the tempering furnace body 12 is fixedly installed with a first lifting cylinder 23 by bolts. The lower mold 21 is fixedly installed on the top of the first lifting cylinder 23 and is located at the bottom of the rotating bracket 15. The top of the tempering furnace body 12 is fixedly installed with a second lifting cylinder 24 by bolts. The upper mold 22 is fixedly installed at the bottom of the second lifting cylinder 24 and the upper mold 22 and the lower mold 21 are matched. The upper mold 22 is located at the top of the rotating bracket 15.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The hot bending bonding assembly also includes a heating spray gun 25, an inlet pipe 26, and an outlet pipe 27. The inlet pipe 26 is fixedly installed at one top end of the upper mold 22, and the outlet pipe 27 is fixedly installed at the other top end of the upper mold 22. Both the inlet pipe 26 and the outlet pipe 27 extend into the interior of the soft capsule 20. The liquid medium inside the soft capsule 20 is transported, cooled, connected to the hydraulic system, and its hydraulic pressure is maintained and adjusted by the inlet pipe 26 and the outlet pipe 27. A hydraulic system composed of conventional hydraulic pumps, air pumps, pressure regulating valves, and other pressure regulating devices can achieve pressure adjustment of the liquid medium. This patent will not elaborate further. The furnace body 10 has several heating guns 25 at both ends of the rotating bracket 15. The pre-ignited heating guns 25 continue to soften the glass to the limit to meet the bending requirements. Several heating tubes 28 are evenly installed at the bottom of the lower mold 21 by bolts. The soft capsule 20 is wrapped with a heat-insulating and wear-resistant layer. The liquid medium inside the soft capsule 20 can be water or other non-polluting, non-flammable, non-corrosive, and non-expanding liquid at high temperatures. The soft capsule 20 is elastic, high-temperature resistant rubber, and is wrapped with ultra-fine cloth that is more heat-resistant and abrasion-resistant. The heat-insulating and wear-resistant material layer is such as glass fiber cloth or glass fiber, stainless steel metal wire cloth, etc.

[0038] See Figure 1 , Figure 2 , Figure 3 and Figure 4The heated glass is transported to the interior of the hot bending furnace 10 via the conveying friction roller 14 on the base transfer frame 13, so that the glass is in a softened but firm state. When the glass enters the top of the rotating bracket 15 of the hot bending furnace 10, the pre-ignited heating gun 25 further softens the glass to the limit to meet the bending requirements. At this time, the PLC controller controls the first lifting cylinder 23 to drive the lower mold 21 to move upward. The lower mold 21 lifts the glass on the rotating bracket 15. At the same time, the second lifting cylinder 24 drives the upper mold 22 and the soft capsule 20 to move downward. The soft capsule 20 presses the glass down and adheres it to the lower mold 21. The PLC controls the upper and lower molds 21 to open and close to the stop point. The soft capsule 20, the upper mold 22 and the lower mold 21 are used to hot bend the glass on the rotating bracket 15.

[0039] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The tempering furnace body 12 is equipped with an annular cooling assembly for cooling the hot-bent glass. A fan frame 30 within the annular cooling assembly cools the hot-bent glass. The annular cooling assembly also includes a cooling base plate 40 for placing the hot-bent glass. The cooling base plate 40 causes the hot-bent glass to move around the fan frame 30 for cooling. The annular cooling assembly also includes cross-shaped fixing brackets 34 fixedly installed at both ends of the bottom of the tempering furnace body 12. Each cross-shaped fixing bracket 34 has a first sliding groove 35 horizontally on the side away from the fan frame 30, and a first sliding groove 35 vertically on the side away from the fan frame 30. The first slide 35 is slidably connected to the second slide 36. The fan frame 30 is movable between the cross-shaped fixing frame 34. Inside the tempering furnace body 12, there are support frames 42 at both ends of the fan frame 30. The top of the support frame 42 is movably connected to the support shaft 43. The support shaft 43 is fixedly installed with a fixed gear 44 at one end near the fan frame 30. The first slide 35 is slidably connected to the first slide 37. The second slide 36 is slidably connected to the second slide 38. The first slide 35 and the second slide 36 are connected through each other. The first slide 37 and the second slide 38 are connected to a rotating plate 33 on the side away from the fan frame 30.

[0040] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9A rotary motor 11 is fixedly installed on one side of the tempering furnace body 12. The output end of the rotary motor 11 is connected to a rotary shaft 48. First pulleys 45 are fixedly installed at both ends of the rotary shaft 48. Second pulleys 46 are fixedly installed at the end of the supporting rotating shaft 43 away from the fan frame 30. A transmission belt 47 connects the second pulleys 46 and the first pulleys 45. A movable gear 39 is fixedly installed on the side of the rotating plate 33 away from the fan frame 30. The movable gear 39 is in movable mesh with the fixed gear 44. Several staggered first fans 31 are arranged at both ends inside the fan frame 30. Air can be blown from both sides of the fan frame 30. When the fan frame 30 moves to the top side of the cooling base plate 40, air is discharged from the bottom of the fan frame 30 for cooling. When the fan frame 30 moves to the bottom side of the cooling base plate 40, air is discharged from the top of the fan frame 30 for cooling. A battery pack 32 that provides power to the first fan 31 is fixedly installed in the center of the fan frame 30. The cooling base plate 40 is evenly provided with several strip grooves 41. Air is blown to cool the bottom of the hot-bent glass product through the strip grooves 41. The upper and lower sides of the fan frame 30 are both conical structures, and ventilation holes are provided on both the upper and lower sides of the fan frame 30.

[0041] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The rotating motor 11 on the outside of the tempering furnace body 12 drives the first pulleys 45 at both ends of the rotating shaft 48 to rotate. The first pulleys 45 drive the second pulleys 46 on the supporting shaft 43 to rotate synchronously via the transmission belt 47. The supporting shaft 43 rotates smoothly and stably at the top of the support frame 42. The supporting shaft 43 drives the fixed gear 44 to rotate. The fixed gear 44 meshes with and drives the outer movable gear 39 to rotate. When the movable gear 39 rotates around the fixed gear 44, it synchronously drives the rotating plate 33 to rotate outside the fixed gear 44. At this time, the first slider 37 and the second slider 38 at both ends of the rotating plate 33 will move synchronously. The first slider 37 will reciprocate horizontally along the first slide groove 35, while the second slider 38 will reciprocate vertically along the second slide groove 36. When the first slider... When the first slide 37 moves toward the fixed gear 44 in the first slide 35, the second slide 38 moves away from the fixed gear 44 in the second slide 36. Similarly, when the first slide 37 moves away from the fixed gear 44 in the first slide 35, the second slide 38 moves toward the fixed gear 44 in the second slide 36. This process repeats, causing the first slide 37 to drive the cooling base plate 40 to move horizontally back and forth, while the second slide 38 drives the fan frame 30 to move vertically back and forth. The fan frame 30 will perform cooling in a circular motion around the cooling base plate 40 in the vertical direction. The fan frame 30 will move to the bottom, top, or sides of the cooling base plate 40. The first fan 31 inside the fan frame 30, in conjunction with the battery pack 32, cools the glass products on the cooling base plate 40. The airflow of the first fan 31 inside the fan frame 30 is staggered to improve the uniformity of cooling of the glass products.

[0042] See Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11Inside the tempering furnace body 12, at the end furthest from the hot bending furnace body 10, a horizontal cooling component is provided to reciprocate and cool the hot-bent glass. A base fan box 59 of the horizontal cooling component reciprocates and cools the bottom of the hot-bent glass. A rotating disk inside the tempering furnace body 12 drives the base fan box 59 to reciprocate horizontally at the bottom of the cooling base plate 40. The horizontal cooling component also includes a first bevel gear 49 fixedly mounted on a rotating shaft 48. A base plate 50 is fixedly mounted at the bottom of the tempering furnace body 12 at the end furthest from the hot bending furnace body 10. A connecting shaft 51 is movably connected to the top of the base plate 50. A second bevel gear 53 is fixedly mounted at one end of the connecting shaft 51, and the second bevel gear 53 meshes movably with the first bevel gear 49. A connecting plate 54 is fixedly mounted at the other end of the connecting shaft 51, located furthest from the first bevel gear 49. An arc-shaped limiting rod 55 is fixedly installed on one side of the 9. An arc-shaped rotating ring 56 is movably sleeved on the outside of the arc-shaped limiting rod 55. The arc-shaped limiting rod 55 moves to the upper and lower ends of the support plate. The arc-shaped limiting rod 55 is located at both ends of the arc-shaped rotating ring 56. The arc-shaped limiting rod 55 moves to the left and right ends of the support plate. The arc-shaped limiting rod 55 is located at the middle of the arc-shaped rotating ring 56. Connecting plates 57 are fixedly installed at both ends of the bottom of the tempering furnace body 12 on the side of the connecting plate 54 away from the first bevel gear 49. The top of the connecting plates 57 is movably sleeved with moving rods 58. One end of the moving rods 58 is fixedly installed on the arc-shaped rotating ring 56. The other end of the moving rods 58 is fixedly installed with a base fan box 59. A second fan 52 is fixedly installed inside the base fan box 59. The second fan 52 is movable at the bottom of the cooling base plate 40.

[0043] See Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11 When the cooling base plate 40 moves horizontally to the end near the push box 60, the first bevel gear 49 on the rotating shaft 48 meshes with the second bevel gear 53 and rotates. The second bevel gear 53 drives the connecting shaft 51 on the base plate 50 to rotate synchronously. The connecting shaft 51 drives the connecting plate 54 to rotate. During the rotation of the connecting plate 54, the arc-shaped limiting rod 55 drives the arc-shaped rotating ring 56 to move. During the movement, the arc-shaped rotating ring 56 drives the moving rod 58 on the connecting plate 57 to move horizontally. The moving rod 58 drives the second fan 52 in the base fan box 59 to reciprocate. The second fan 52 blows air horizontally and reciprocally on the glass products on the cooling base plate 40 to cool them, thereby improving the cooling effect and the uniformity of the internal stress of the glass products.

[0044] See Figure 10 , Figure 12 and Figure 13Inside the tempering furnace body 12, at the end furthest from the hot bending furnace body 10, there is a material unloading and pushing assembly for pushing cooled glass. The material unloading and pushing assembly includes a pushing box 60, a movable suction cup 67 for gripping the glass, and a servo motor 61 installed inside the pushing box 60. The pushing box 60 is installed on the inner top of the tempering furnace body 12 via a connecting column. A screw 62 is fixedly installed at the output end of the servo motor 61. A pushing block 63 is threaded through the screw 62. The bottom of the pushing block 63 is connected to an electric telescopic rod 65 via a pushing rod 64. The bottom of the electric telescopic rod 65 is connected to the movable suction cup 67 via a moving plate 66. A positioning rod 68 is installed inside the pushing box 60. Both ends of the pushing block 63 move within the positioning rod 68. A pushing groove 69 is opened at the bottom of the pushing box 60, and the pushing rod 64 moves through the pushing groove 69. The movable suction cup 67 moves at the top of the cooling base plate 40 and the conveying friction roller 14.

[0045] See Figure 10 , Figure 12 and Figure 13 The servo motor 61 inside the push box 60 drives the push block 63 on the screw 62 to reciprocate horizontally under the action of the positioning rod 68. The push rod 64 drives the movable suction cup 67 under the electric telescopic rod 65 through the push groove 69 to stably grip the glass product. After gripping, the screw 62 and the push block 63 drive the glass product under the movable suction cup 67 to move onto the conveying friction roller 14 of the base transmission frame 13. The conveying friction roller 14 is used to transport the processed glass product out.

[0046] Working principle: The heated glass is transported to the interior of the hot bending furnace 10 via the conveying friction roller 14 on the base conveyor frame 13, so that the glass is in a softened but firm state. When the glass enters the top of the rotating bracket 15 of the hot bending furnace 10, the pre-ignited heating gun 25 further softens the glass to the limit to meet the bending requirements. At this time, the PLC controller controls the first lifting cylinder 23 to drive the lower mold 21 to move upward. The lower mold 21 lifts the glass on the rotating bracket 15. At the same time, the second lifting cylinder 24 drives the upper mold 22 and the soft capsule 20 to move downward. The soft capsule 20 presses the glass down and adheres it to the lower mold 21. The PLC controls the upper and lower molds 21 to open and close to the stop point. The glass on the rotating bracket 15 is hot bent into shape by the soft capsule 20, the upper mold 22 and the lower mold 21. Then, the hot-bent glass is transported again to the conveying friction roller 14 in the tempering furnace 12 by the rotating support roller 16 on the rotating bracket 15 to continue moving and transporting.

[0047] The hot-bent glass product is transported to the cooling base plate 40 by the conveying friction roller 14. The first pulley 45 at both ends of the rotating shaft 48 is driven to rotate by the rotary motor 11 on the outside of the tempering furnace body 12. The first pulley 45 drives the second pulley 46 on the supporting rotating shaft 43 to move synchronously through the transmission belt 47. The supporting rotating shaft 43 rotates smoothly and stably at the top of the support frame 42. The supporting rotating shaft 43 drives the fixed gear 44 to rotate. The fixed gear 44 meshes with the outer movable gear 39 to rotate. When the movable gear 39 rotates around the fixed gear 44, it synchronously drives the rotating plate 33 to rotate outside the fixed gear 44. At this time, the first slider 37 and the second slider 38 at both ends of the rotating plate 33 will move synchronously. The first slider 37 will reciprocate horizontally along the first slide groove 35, while the second slider 38 will move horizontally along the second slide groove 36. 6. A reciprocating vertical motion occurs. When the first slider 37 moves towards the fixed gear 44 in the first slide groove 35, the second slider 38 moves away from the fixed gear 44 in the second slide groove 36. Similarly, when the first slider 37 moves away from the fixed gear 44 in the first slide groove 35, the second slider 38 moves towards the fixed gear 44 in the second slide groove 36. This reciprocating motion causes the first slider 37 to drive the cooling base plate 40 to reciprocate horizontally, while the second slider 38 drives the fan frame 30 to reciprocate vertically. The fan frame 30 will perform cooling in a circular motion around the cooling base plate 40 in the vertical direction. The fan frame 30 will move to the bottom, top, or sides of the cooling base plate 40. The first fan 31 inside the fan frame 30, in conjunction with the battery pack 32, cools the glass products on the cooling base plate 40. The airflow of the first fan 31 inside the fan frame 30 is staggered to improve the uniformity of cooling of the glass products.

[0048] When the cooling base plate 40 moves horizontally to the end near the push box 60, the first bevel gear 49 on the rotating shaft 48 meshes with the second bevel gear 53 and rotates. The second bevel gear 53 drives the connecting shaft 51 on the base plate 50 to rotate synchronously. The connecting shaft 51 drives the connecting plate 54 to rotate. During the rotation of the connecting plate 54, the arc-shaped limiting rod 55 drives the arc-shaped rotating ring 56 to move. During the movement, the arc-shaped rotating ring 56 drives the moving rod 58 on the connecting plate 57 to move horizontally. The moving rod 58 drives the second fan 52 in the base fan box 59 to reciprocate. The second fan 52 blows air horizontally and reciprocally on the glass products on the cooling base plate 40 to cool them, thereby improving the cooling effect and the uniformity of the internal stress of the glass products.

[0049] After the glass product is cooled to below 100°C, the servo motor 61 in the push box 60 drives the push block 63 on the screw 62 to reciprocate horizontally under the action of the positioning rod 68. The push rod 64 drives the movable suction cup 67 under the electric telescopic rod 65 through the push groove 69 to stably grip the glass product. After gripping, the screw 62 and the push block 63 drive the glass product under the movable suction cup 67 to move onto the conveying friction roller 14 of the base transmission frame 13. The conveying friction roller 14 is used to transport the processed glass product out.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
