[0002] As we all know, glass tempering refers to: through complex tempering treatment, a compressive stress is formed on the surface of the glass. When the glass is subjected to external force, the surface stress will offset part of the external force, so that the external force on the glass itself is weakened, thereby achieving an increase in the bearing capacity; the glass tempering process is often carried out in a tempering furnace, and during this process, the glass needs to be sent to the tempering furnace by a conveying equipment.

[0003] Chinese utility model patent CN219409558U discloses an automatic glass tempering furnace loading machine that is easy to adjust in height. A workbench is installed on the upper side of the loading machine body, and a suction cup flip frame is installed on one side of the workbench to facilitate workers to stack glass plates on the workbench. When the automatic glass tempering furnace loading machine is not stacking glass plates, dust is not easy to fall on the table. However, by adjusting the height of the entire loading machine to meet the height requirement of the glass being loaded to the tempering furnace, energy consumption is high and the adjustment convenience is poor. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a tempering furnace loading platform which is convenient for adjusting the height of the glass loading plate, has a more reasonable structural layout, and effectively reduces the energy consumption of the equipment.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-4 The utility model provides a tempering furnace loading platform, including a conveying mechanism and a height-adjusting loading mechanism installed at the discharge end of the conveying mechanism. The conveying mechanism in this embodiment includes a frame 14, a plurality of conveying rollers 15 rotatably installed on the frame 14, and a motor 16 providing power for the rotation of the conveying rollers 15. The output end of the motor 16 is connected to each conveying roller 15 through a transmission belt 17. The glass is placed on the plurality of conveying rollers 15, and the transmission belt 17 is driven to rotate by the motor 16. The transmission belt 17 drives the plurality of conveying rollers 15 to transmit synchronously, thereby realizing horizontal transmission of the glass.

[0029] The height-adjustable film loading mechanism includes a frame 1, a slide 2 slidably mounted on the frame 1, a flip frame 3 rotatably mounted on the slide 2, and an adjustment platform 4 mounted on the flip frame 3. A sliding drive assembly 5 for providing power for the sliding of the slide 2 is mounted on the frame 1, a driving cylinder 6 for providing power for the rotation of the flip frame 3 is mounted on the slide 2, two limit rods 7 are mounted on the flip frame 3, and the connecting surface formed between the adjustment platform 4 and the central axis of the two limit rods 7 is arranged in parallel.

[0030] Two symmetrically arranged supporting rollers 18 are slidably mounted on the conveying roller 15. The supporting rollers 18 are provided with an annular supporting portion 19. The edges of both sides of the glass are placed on the annular supporting portion 19 of the supporting rollers 18 to limit the positions of both sides of the glass, further ensuring the accuracy of the position of the glass on the plate. A rubber ring 20 is sleeved on the annular supporting portion 19, and the rubber ring 20 can realize flexible contact between the annular supporting portion 19 and the glass, thereby preventing the glass from being scratched by the supporting rollers 18 during the conveying process.

[0031] The supporting wheel 18 is slidably mounted on the conveying roller 15 and is fixedly connected to the conveying roller 15 by bolts. The distance between the two supporting wheels 18 on the same conveying roller 15 is adjusted to meet the conveying requirements of glass of different widths and improve the applicability of the conveying mechanism.

[0032] One end of the driving cylinder 6 is hinged to the slide 2, and the other end of the driving cylinder 6 is hinged to the flip frame 3; the adjusting table 4 can adopt a turbine screw lifting table, a scissors-type lifting table or other equivalent parts with supporting lifting effects, preferably a scissors-type lifting table; the sliding drive component 5 can adopt a hydraulic cylinder or a pneumatic cylinder, or it can adopt an equivalent part with linear driving effect such as a ball screw component; more specifically, when the sliding drive component 5 is fully extended, that is, when the slide 2 moves to the extreme state, the edge of the glass just enters the tempering furnace, and the limit rod 7 limits the loading position of the glass on the adjusting table 4, so that the loading position of each glass end is consistent with the adjusting table 4, so that the glass can enter the tempering furnace accurately and smoothly, and the limit adjustment of the glass loading height and the loading position at the end is simultaneously realized, effectively improving the loading accuracy of the glass into the tempering furnace.

[0033] See also Figure 5 A photoelectric sensor 23 is installed on the frame 14 near the height adjustment loading mechanism; the photoelectric sensor 23 is electrically connected to the motor 16 through an external PLC system. When the photoelectric sensor 23 senses the head and tail of the glass, the signal is transmitted to the motor 16 through the external PLC system, and the motor 16 stops running to ensure that the glass is loaded to the height adjustment loading mechanism in a single piece state, avoiding the next glass from interfering with the glass on the height adjustment loading mechanism.

[0034] See also Figure 6-8 The adjustment platform 4 in this embodiment includes a base 8, a first transmission rod 9, a second transmission rod 10, a lifting frame 11 and a lifting drive assembly. The middle parts of the first transmission rod 9 and the second transmission rod 10 are hinged, and one adjacent end of the first transmission rod 9 and the second transmission rod 10 is hinged to the base 8 and the lifting frame 11 respectively. The other adjacent ends of the first transmission rod 9 and the second transmission rod 10 are slidably connected to the base 8 and the lifting frame 11 respectively. The lifting drive assembly includes a threaded screw 12 rotatably mounted on the lifting frame 11, a driving cross bar 13 threadedly connected to the threaded screw 12, and a driving motor 24 that provides power for the rotation of the threaded screw 12. The driving cross bar 13 is rotatably connected to the second transmission rod 10; the driving motor 24 drives the threaded screw 12 to rotate. After thread transmission, the driving cross bar 13 drives one end of the second transmission rod 10 to approach the middle part of the lifting frame 11. After transmission by the first transmission rod 9 and the second transmission rod 10, the distance between the lifting frame 11 and the base 8 changes, so as to achieve height adjustment of the lifting frame 11.

[0035] A plurality of rollers 21 are rotatably mounted on the lifting frame 11, and the rollers 21 are rotatably connected to the lifting frame 11 through an inertial bearing. The rollers 21 can reduce the friction between the lifting frame 11 and the rollers 21, and when the glass is unloaded at the lifting frame 11, the glass can be moved out of the lifting frame 11 more smoothly. The limit rod 7 and the rollers 21 in this embodiment are both soft rubber rollers, which can avoid direct hard contact between the limit rod 7 and the rollers 21 and the glass, so as to prevent damage to the glass.

[0036] Two sockets 22 are provided on the frame 14, and the sockets 22 can be used for the forks of an external forklift to be inserted. Before the glass enters the tempering furnace, some of the glass needs to be cleaned, and a cleaning machine needs to be added. However, if the outlet of the cleaning machine is directly connected to the entrance of the tempering furnace, when producing glass that does not need to be cleaned, the glass cannot be loaded because the space is occupied by the cleaning machine; the loading platform can be used as a "transition section". When the glass needs to be cleaned, the forklift is inserted into the socket 22, the loading platform is moved away, and the cleaning machine is moved in; when cleaning is not required, the loading platform is moved in, thereby meeting production needs, and the socket 22 can provide a better fulcrum for the forklift, thereby improving the movement stability of the loading platform.

[0037] When in use, the glass is horizontally conveyed by the conveying mechanism until the end of the glass contacts the two limit rods 7, and then the output end of the driving cylinder 6 is extended, and the turning frame 3 is turned over by the driving cylinder 6, and the adjustment table 4 gradually changes from a vertical state to a horizontal state. At the same time, the sliding drive assembly 5 drives the slide 2 to move away from the conveying mechanism until the glass is completely moved to the horizontal adjustment table 4. At this time, the limit rod 7 is in a horizontal placement state, and the driving motor 24 drives the threaded screw 12 to rotate. After thread transmission, the driving cross bar 13 drives one end of the second transmission rod 10 to approach the middle of the lifting frame 11. After transmission by the first transmission rod 9 and the second transmission rod 10, the distance between the lifting frame 11 and the base 8 changes, so as to realize the height adjustment of the lifting frame 11 and complete the adjustment of the feeding height position of the glass.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
