Description

Technical Field

[0002] Glass bottle is a common container, usually made of raw materials such as silica (i.e. sand), alkali and limestone, which are melted at high temperature and then blown and pressed into shape. With the development of technology, the production process of glass bottles has been continuously innovated. Today's glass bottles are larger, thin-walled, transparent and smooth. Glass bottles have the advantages of good chemical stability, sealing and recyclability. When using glass bottles, you need to pay attention to avoid collision, cleaning and high temperature to ensure the safety and reliability of the glass bottles. In the production process of glass bottles, glass bottles are easy to deform when placed in high-temperature flavoring nozzles. Therefore, in order to ensure the strength of the glass bottles, it is necessary to first use heating equipment to heat the mouth of the glass bottle, and then cool and recrystallize it to make it able to withstand higher temperatures.

[0003] When heating the mouth of a glass bottle, it is difficult to control the temperature difference on the glass bottle by using a flamethrower for one-time heating.

[0017] 1. The glass bottle heating equipment can limit and clamp the glass bottle to be processed through the setting of the limiter, and cooperate with the rotating table to make the glass bottle rotate under the fixation of the limiter, and then use the lifter to move the preheater down to evenly preheat the bottle mouth area of ​​the glass bottle to reduce the local temperature difference and prevent the glass bottle from breaking due to thermal stress in subsequent processing.

[0018] 2. The glass bottle heating equipment generates heat through the cooperation of the electric heater and the heating element, and cooperates with the setting of the converging inclined plate to block the heat from diffusing so that the heat is gathered in the cavity formed by the insulating ring plate and the fixed cover plate, and then uses the flat air supply plate and the arc air supply plate to surround the heating element to further gather heat, and then uses the cooperation of the motor and the screw rod to make the lifting plate drive the preheater to descend, and cooperates with the surrounding of the heating element on the outside of the glass bottle and the narrow thermal contact surface formed by the flat air supply plate and the arc air supply plate, thereby ensuring the heating efficiency of the preheating of the outside of the glass bottle, thereby achieving efficient heating of the mouth of the glass bottle.

[0019] 3. The glass bottle heating equipment, through the cooperation of the air guide box and the air supply pipe, guides the clean air to the air gathering ring plate for convergence, and cooperates with the guide pipe to send it into the cavity formed by the heat insulation ring plate and the fixed cover plate, and then utilizes the arc surface design of the air guide arc plate to make the air circulate and circulate in the heat insulation ring plate and the fixed cover plate, and then discharges from the narrow opening between the flat air supply plate and the arc air supply plate, accelerates the circulation of hot air, and thus gathers it on the surface of the glass bottle, thereby increasing the preheating speed of the glass bottle mouth and improving the heating output efficiency of the equipment.

[0020] Fourth, the glass bottle heating equipment, through the arc setting of the arc-mouth air supply plate, concentrates the airflow and blows the hot air in an inclined direction, and cooperates with the flat setting of the flat-mouth air supply plate, so that the airflow converges from the inner arc surface of the flat-mouth air supply plate and mixes with the hot air blown in the inclined direction of the arc-mouth air supply plate when discharged, so that the hot air discharged between the flat-mouth air supply plate and the arc-mouth air supply plate is evenly distributed and blown to the surface of the glass bottle, thereby ensuring that the glass bottle is heated evenly during the heating process.

[0021] 5. The glass bottle heating equipment can adaptively fix glass bottles with different bodies when they are placed on the platform through the coordination of the arc-shaped clamping plate and the roller. The arc-shaped clamping plate is pushed by the glass bottle body to drive the push rod to slide in the outer cylinder and compress the spring part to deform. The rebound force generated by the pressure on the spring part is utilized to push the arc-shaped clamping plate and the roller in the reverse direction to further tighten the glass bottle.

The setting of the roller 532 makes it faster and more convenient to remove the glass bottle after preheating.

[0045] The working principle of the glass bottle heating equipment is described in detail below.

[0046] When in use, the staff places the glass bottle to be processed on the support platform 51, and uses the arc clamping plate 531 to be pushed by the glass bottle body to drive the push rod 523 to slide in the outer cylinder 522, and compress the spring member 524 to deform, and use the rebound force generated by the compression of the spring member 524 to push the arc clamping plate 531 and the roller 532 in the opposite direction to further tighten the glass bottle, and then use the output shaft of the servo motor 22 to drive the workbench 21 to rotate on the frame 1, so that the glass bottle rotates under the fixation of the limiter 5, and then use the output shaft of the motor 32 to rotate the workbench 21 on the frame 1. The rotation of the output shaft drives the screw rod 33 to rotate, so that the lifting plate 34 drives the mounting plate 41 to move downward, and the electric preheating element 43 is used to uniformly preheat the bottle mouth area of ​​the glass bottle, reduce the local temperature difference and adopt annular heating rather than single-direction heating to ensure that the heat surrounds the bottle mouth uniformly from multiple angles, reduce the formation of hot spots, and at the same time, the outside air is guided by the air guide box 421 to filter it, and the clean air is guided to the air gathering ring plate 423 by the air supply pipe 422 for convergence, and is sent to the heat insulation ring plate 432 and the fixed cover plate 432 in conjunction with the guide pipe 424. 33, and then use the arc surface of the air guide arc plate 434 to make the air circulate in the heat insulation ring plate 432 and the fixed cover plate 433, and be discharged from the narrow opening between the flat air supply plate 438 and the arc air supply plate 439, so as to accelerate the circulation of hot air and gather the heat on the surface of the glass bottle. In addition, the flat air supply plate 438 and the arc air supply plate 439 are used to surround the heating element 436 to further gather the heat. Through the arc setting of the arc air supply plate 439, the air flow is concentrated and the hot air is blown in an inclined direction. The flat-mouth setting of 38 allows the airflow to converge from the inner curved surface of the flat-mouth air supply plate 438 and mix with the hot air blown along the inclined direction of the curved-mouth air supply plate 439 when it is discharged, so that the hot air discharged between the flat-mouth air supply plate 438 and the curved-mouth air supply plate 439 is evenly distributed and blown to the surface of the glass bottle, thereby efficiently heating the mouth of the glass bottle. After the preheating is completed, the preheater 4 rises as a whole and separates from the mouth of the glass bottle, and then the servo motor 22 is used to drive the workbench 21 to rotate, and the next glass bottle to be processed is rotated to the bottom of the preheater 4 for heating.
