DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Reference Figure 1-Figure 9 A glass product annealing furnace with a bottle pushing mechanism comprises a table body 1, an annealing furnace body 2 is fixedly installed on the upper surface of the table body 1, two pairs of mounting plates 3 are symmetrically fixedly installed on the upper surface of the table body 1, a rotating shaft 4 is horizontally rotatably installed between each pair of mounting plates 3, a transmission roller 5 is fixedly sleeved on the rotating shaft 4, and a conveyor belt 6 is wound around the two transmission rollers 5, a driving motor 7 is fixedly installed on the surface of one of the mounting plates 3, and the output shaft of the driving motor 7 is fixedly connected to one of the rotating shafts 4.

[0018] An L-shaped vertical plate 8 is fixedly installed on the back of the platform 1 through a support rod, and a first rotating rod 9 and a second rotating rod 10 are installed horizontally and rotatably on the surface of the vertical plate 8. A reciprocating screw rod 11 is fixedly installed on one end of the second rotating rod 10, and a sliding rod 12 is threadedly sleeved on the reciprocating screw rod 11. A rectangular through-hole is opened on the upper surface of the sliding rod 12, and a plug rod 13 with a rectangular cross section is slidably inserted in the through-hole. A push plate 14 is fixedly installed on the bottom end of the plug rod 13, and a mounting block is fixedly installed on the top end of the plug rod 13. The mounting block is fixedly connected to the sliding rod 12 through a telescopic component, and the telescopic component includes a sleeve A telescopic spring 18 is arranged on the insertion rod 13, and the two ends of the telescopic spring 18 are fixedly connected to the mounting block and the slide rod 12 respectively. The first rotating rod 9 and the output shaft of the driving motor 7 are fixedly sleeved with a bevel gear 15, and the two bevel gears 15 are meshingly connected. The first rotating rod 9 and the second rotating rod 10 are fixedly sleeved with a sprocket 16, and the two sprockets 16 are meshingly wound with a chain 17. The slide rod 12 is restricted in rotation by a limiting component, and the limiting component includes a limiting rod 19 fixedly installed horizontally on the surface of the vertical plate 8, and the slide rod 12 is slidably sleeved on the limiting rod 19.

[0019] When the drive motor 7 is started, the output shaft of the drive motor 7 will rotate with one of the rotating shafts 4 and the transmission roller 5. At this time, under the transmission action of the conveyor belt 6, the other rotating shaft 4 and the transmission roller 5 will also rotate together, thereby realizing the operation of the conveyor belt 6.

[0020] When the output shaft of the driving motor 7 rotates, the bevel gear 15 fixedly sleeved on the output shaft of the driving motor 7 will rotate, and the bevel gear 15 meshing with the bevel gear 15 and fixedly sleeved on the first rotating rod 9 will also rotate with the first rotating rod 9, and then under the transmission action of the two sprockets 16 and the chain 17, the second rotating rod 10 will rotate with the reciprocating screw rod 11.

[0021] When the reciprocating screw 11 rotates, the sliding rod 12 threadedly connected to the reciprocating screw 11 will carry the insertion rod 13 and the push plate 14 to move back and forth laterally under the limiting action of the limiting rod 19. When the push plate 14 moves in the direction close to the annealing furnace body 2, the push plate 14 will push the glass products on the upper surface of the table 1 onto the conveyor belt 6, and then the conveyor belt 6 will transport the glass products into the annealing furnace body 2. When the push plate 14 moves in the direction away from the annealing furnace body 2 and resets, it will push the subsequent glass products onto the conveyor belt 6. That is, only one set of electric drive device is needed to achieve the effect of controlling the operation of the conveyor belt 6 and the lateral reciprocating movement of the push plate 14, which reduces the volume occupied by the equipment and also reduces the electricity cost required during the annealing process.

[0022] The mounting block is fixedly mounted with an inclined plate 20 on the side wall close to the annealing furnace body 2, a rectangular plate is fixedly mounted on the top of the annealing furnace body 2, a trapezoidal pressing plate 21 is horizontally fixedly mounted on the surface of the rectangular plate, the inclined surface of the pressing plate 21 is arranged face to face with the inclined surface of the inclined plate 20, a locking assembly is provided on the upper surface of the slide bar 12, the locking assembly is used to lock the insertion rod 13, the locking assembly includes a support plate 22 fixedly mounted on the upper surface of the slide bar 12, a spring rod 23 fixedly mounted on the surface of the support plate 22 horizontally, and a spring rod 23 fixedly mounted on the spring rod 23 A triangular locking block 24 is provided at one end, and a trapezoidal vertical block 25 is vertically fixedly installed on the upper surface of the mounting block. The inclined surface of the vertical block 25 is arranged face to face with the inclined surface of the locking block 24. A locking opening 26 for the locking block 24 to enter is opened on the surface of the vertical block 25. The spring rod 23 is controlled to retract by a pressing assembly. The pressing assembly includes an L-shaped pressing rod 27 vertically fixedly installed on the upper surface of the platform 1 and an inclined rod 28 fixedly installed on the side wall of the locking block 24. The inclined surface of the pressing rod 27 is arranged face to face with the inclined surface of the inclined rod 28.

[0023] When the push plate 14 moves toward the annealing furnace body 2 and pushes the glass product to be annealed to the conveyor belt 6, it will be at the lowest point. As the push plate 14 moves, the inclined plate 20 and the pressure plate 21 will gradually approach each other. When the inclined surface of the pressure plate 21 slides in contact with the inclined surface of the inclined plate 20, the inclined plate 20 will move upward with the insertion rod 13, the push plate 14 and the vertical block 25 under the action of the inclined surface pressure. The telescopic spring 18 will be stretched at this time. When the vertical block 25 moves upward, the inclined surface of the top of the vertical block 25 will contact the locking block 24. The inclined surfaces are in sliding contact, and under the action of the inclined surfaces' pressure, the spring rod 23 will shrink until the upright block 25 moves up to the position where the locking opening 26 opened on the surface corresponds to the position of the locking block 24. At this time, the pressure exerted by the upright block 25 on the locking block 24 disappears, and the locking block 24 will quickly move and reset under the elastic potential energy of the spring rod 23, and be inserted into the locking opening 26, thereby completing the locking of the upright block 25, the insertion rod 13 and the push plate 14. At this time, the push plate 14 will be at the highest point and will move in the direction away from the annealing furnace body 2.

[0024] Since the push plate 14 is at the highest position when it moves and resets, the glass products to be annealed will not be pushed down or blocked during the reset process. Only when the push plate 14 moves and resets, the end of the push rod 27 will slide in contact with the inclined surface of the inclined rod 28. Under the action of the push rod 23, the spring rod 23 will shrink, and the locking block 24 will move out of the locking port 26, thereby releasing the locking of the opposing block 25, the insertion rod 13 and the push plate 14. The upright block 25, the insertion rod 13 and the push plate 14 will quickly move down and reset under the elastic potential energy of the telescopic spring 18, and the push plate 14 will be at the lowest position again. Then, when it moves toward the direction close to the annealing furnace body 2, it will push the glass products to be annealed onto the conveyor belt 6.

[0025] The surface of the push plate 14 close to the annealing furnace body 2 is provided with an arc surface 29 matching the outer contour of the glass product to be annealed. The surface of the arc surface 29 is bonded with an anti-skid layer made of rubber, so that the glass products entering the annealing furnace body 2 are arranged neatly and will not be damaged by the collision of the push plate 14.

[0026] A plurality of spherical grooves are provided on the lower surface of the push plate 14, in which rolling balls 30 are embedded and rolled with the ball 30 for contacting with the table 1 and the conveyor belt 6. The ball 30 can support the push plate 14 while reducing the friction between the contact surfaces of the push plate 14, the table 1 and the conveyor belt 6.

[0027] In the present invention, the drive motor 7 is started, and the output shaft of the drive motor 7 will rotate with one of the rotating shafts 4 and the transmission roller 5. At this time, under the transmission action of the conveyor belt 6, the other rotating shaft 4 and the transmission roller 5 will also rotate together, thereby realizing the operation of the conveyor belt 6. When the output shaft of the drive motor 7 rotates, the bevel gear 15 fixedly sleeved on the output shaft of the drive motor 7 will rotate, and the bevel gear 15 meshing with the bevel gear 15 and fixedly sleeved on the first rotating rod 9 will also rotate with the first rotating rod 9. Then, under the transmission action of the two sprockets 16 and the chain 17, the second rotating rod 10 will rotate with the reciprocating screw rod 11. When the reciprocating screw rod 11 rotates, the screw The sliding rod 12 sleeved on the reciprocating screw rod 11 will move back and forth laterally with the insertion rod 13 and the push plate 14 under the limiting action of the limiting component. When the push plate 14 moves in the direction close to the annealing furnace body 2, the push plate 14 will push the glass products on the upper surface of the table body 1 onto the conveyor belt 6, and then the conveyor belt 6 will transport the glass products into the annealing furnace body 2. When the push plate 14 moves in the direction away from the annealing furnace body 2 and resets, it will push the subsequent glass products onto the conveyor belt 6. That is, only one set of electric drive device is needed to achieve the effect of controlling the operation of the conveyor belt 6 and the lateral reciprocating movement of the push plate 14, which reduces the volume occupied by the equipment and also reduces the electricity cost required during the annealing process.
