The moving direction of the driving chain is the same as the moving direction of the conveying device.
Because the annealing box is in a high-temperature environment, the fan blade cannot be directly driven by the air blowing driving device through the motor. The first motor is started to enable the driving roller to rotate and drive the driving chain to move, so that the driving chain wheel rotates and the fan blades rotate. The driving chain and the driving chain wheel are arranged and used for driving the fan blades to rotate, and air flow is blown into the storage box.

The first transmission rod and the second transmission rod are matched with the reciprocating roller, so that the reciprocating roller can rotate reciprocally.
Because the annealing box is in a high-temperature environment, the reciprocating driving device cannot directly drive the reciprocating drum by using the motor. When the driving sprocket rotates, the first driving gear is driven to rotate, the second driving gear is driven to rotate, the rotating protrusion performs circular motion on the vertical plane, the reciprocating roller is driven to rotate in a reciprocating manner through the first transmission rod and the second transmission rod, and the plurality of reciprocating rollers are driven to rotate synchronously through the synchronous sprocket.

Because the moving speed of the driving chain is greater than that of the storage box, the storage box can slide on the annealing conveyor belt, and the accurate control of the annealing time is not facilitated. When the storage box is placed on the annealing conveyor belt, the anti-skid rod enters the driving groove through the abutting block and is connected with the anti-skid baffle. The abutting block is a spherical sliding block and is elastically abutted with the inner wall of the driving groove to prevent sliding. An anti-slip baffle is arranged to block the movement of the anti-slip rod and limit the driving chain. The anti-slip device is arranged at the side of the driving sprocket along the direction opposite to the conveying direction of the conveying device and is used for enabling the storage box to be conveyed to the goods discharging device more easily.
Further, the shipment device includes: the delivery support frame is arranged on the side of the annealing conveyor belt, a plurality of delivery rollers are arranged above the delivery support frame, the delivery rollers are arranged along the conveying direction of the conveying device, the rotating shafts at two ends of the delivery rollers are connected with the delivery support frame through bearings, the delivery rollers penetrate through the inner sides of two driving chains, the upper surfaces of the delivery rollers and the upper surface of the annealing conveyor belt are located on the same plane, a buffer baffle is arranged on the side of the delivery rollers, the buffer baffle faces the annealing conveyor belt and is located above the driving chains, a directional rod is transversely fixed on the outer side of the buffer baffle, a directional sleeve is sleeved on the directional rod, the other end of the directional sleeve is fixed with the delivery support frame, the moving path of the buffer baffle is parallel to the conveying direction of the delivery rollers, a plurality of springs are arranged on the outer side of the buffer baffle, and the other ends of the springs are fixed with the delivery support frame.
Due to the anti-slip device, the separation of the storage box and the annealing conveyor belt is hindered, and the storage box can not be conveyed to the shipment device. The storage box is conveyed to the shipment roller under the action of the conveying of the annealing conveying belt and the two driving chains, and is driven by the driving chains to move to the buffer baffle to stop. The shipment cylinder passes two drive chain insides for make the drive chain separate the receiver, and make the conveying between annealing conveyer belt and the shipment cylinder continuous, make the conveying of receiver more stable, can also drive the receiver and remove on the shipment cylinder. The buffer baffle is arranged to be elastic and used for reducing the impact degree and protecting the storage box.
Further, the shipment device includes: the pressure sensor is arranged on the buffer baffle; the lifting cylinder is arranged on the shipment support frame and located below the shipment rollers, is located on the inner side of the buffer baffle and adjacent to the buffer baffle, a lifting table is fixed above the lifting cylinder, a plurality of transfer conveying structures are arranged at the top of the lifting table and located between two adjacent shipment rollers and arranged along the axis direction of the shipment rollers, the transfer conveying structures are located between two driving chains and comprise transfer conveying belts, a plurality of anti-slip protrusions are arranged on the surfaces of the transfer conveying belts and are strip-shaped rubber, the transfer conveying belts are arranged along the axis direction of the shipment rollers, and the shipment conveying belts are matched with the transfer conveying belts and are matched with the storage boxes.

Because the driving chain is positioned in the limiting groove, the storage box cannot be directly transmitted to the shipment conveyor belt. After the receiver is sensed to the pressure sensor, control lift cylinder extension makes the transfer conveyer belt upwards move, holds up the receiver, conveys the receiver to shipment conveyer belt. The transfer conveying structure is arranged to be a transfer conveying belt, and if the roller is used, the roller can sink into the limit groove, so that the conveying of the storage box is unstable, and the transfer conveying belt is arranged.

Further, the method comprises the steps of: the lid, the lid is located on the receiver, the lid is connected with receiver upper portion pivot along one side of conveyer's direction of delivery, be provided with a plurality of second blowholes on the lid medial surface, a plurality of second blowholes communicate each other, and communicate with a plurality of first blowholes, evenly be provided with a plurality of second exhaust holes between a plurality of second blowholes, the second exhaust hole sets up on the lid medial surface, the outside lateral surface intercommunication with the lid of second exhaust hole, one side of conveyer's direction of delivery is followed to the lid is the arc angle.
If the glass product bursts, a lot of fragments are generated, which easily damage the inside of the annealing box and easily cause the clamping of the annealing conveyor belt. And placing the storage box cover on an annealing conveyor belt after the cover is covered. Because the receiver is covered by the lid, external air current can't get into from the top, sets up second blowhole and second exhaust hole for make the holistic heat exchange of glassware even. The second blowing holes and the second exhaust holes are alternately arranged and used for enabling the glass products to be heated uniformly.

The insulating device generally adopts a fixed insulating table, and when facing glass products with different heights, the distance between the lower part of the insulating table and the annealing conveyor belt needs to be changed, which is very troublesome. The storage box pushes the heat insulation plate to rotate under the conveying of the annealing conveying belt, and then enters the next temperature interval. The protective roller is arranged, so that the protective roller can be connected with the annealing conveyor belt, and the insulation device has better separation effect on the inner space of the annealing box. If the cover is not arranged, the heat insulation plate can be contacted with the glass product to damage the glass product, and the heat insulation plate is matched with the cover to protect the glass product.

When the storage box is conveyed out of the annealing box, the storage box has a certain temperature, so that the anti-skid protrusions are easy to age, and the service life of the anti-skid protrusions is reduced. When receiver and buffer baffle contact, drive chain and drive sprocket still are the meshing state, and the fan of blowing can blow in the receiver with the outside air and cool down it.
A control method of a low stress glass production system comprises the following steps when a storage box is conveyed to a fire box, wherein the fire box comprises the following steps: b1: the control system controls the first motor to rotate forward for 10 seconds; b2: the control system controls the first motor to rotate reversely for 10 seconds; b3, repeating the steps B1 and B2 in sequence until the storage box is conveyed out of the annealing box.

During this time, the blower driving device drives the fan blades 421 to rotate, blows air outside the storage box 4 into the storage box 4 through the plurality of first blowing holes 432, exchanges heat with the bottom of the glass product, and then discharges the air from the plurality of first exhaust holes 431. Meanwhile, the reciprocating driving device drives the plurality of reciprocating rollers 43 to reciprocate, so that the glass product reciprocates, and the bottom of the glass product uniformly contacts with air. The storage box 4 passes through the annealing box 5 and then is transferred to the shipment device. Limiting protrusions 32 and limiting grooves are arranged and used for preventing the storage box 4 from deviating from the annealing conveyor belt 31, and the storage box cannot be accurately conveyed to a cargo discharging device.

The first motor is started to rotate the driving roller 2, drive the driving chain 21 to move, rotate the driving sprocket 44 and rotate the fan blade 421. A drive chain 21 and a drive sprocket 44 are provided for driving the rotation of the fan blade 421 to blow an air flow into the housing box 4.

The glass product is placed in the center of the storage box 4, and a certain distance is reserved between the glass product and the inner wall of the storage box 4, so that the glass product is prevented from colliding with the inner wall of the storage box 4. The rotation shafts at both ends of the first driving gear 45 penetrate the lower portion of the storage case 4 and are fixed to the rotation shafts of the two driving sprockets 44, respectively, so that the reciprocating roller 43 and the fan blades 421 can be continuously operated when the driving sprocket 44 and the driving chain 21 at one side cannot be engaged due to the inclination of the storage case 4.
