[0025] Preferably, the U-shaped frame is threadedly connected with an unlocking bolt that cooperates with the slot.

[0026] A method for operating a calender for glass production comprises the following steps:

[0027] S1. When adjusting the distance between the two calendering rollers, first use the cylinder push rod to push the plate frame and the sleeve to move, and the sleeve uses the connecting rod to push the two connecting shafts and the calendering rollers to move in opposite directions, so that the calendering distance increases;

[0028] S2. Before adjusting the calendering cylinder pitch, press the control pin along the sleeve, the bar-shaped teeth in the bottom groove push the ball column to rotate, and drive the two slip rings to rotate in opposite directions along the cone mouth, so that the T-shaped teeth on the two slip rings are dislocated and unlocked, and then the inclined table pushes the ball column upward, and the top of the ball column squeezes the two slip rings along the cone mouth to move in opposite directions, at this time the T-shaped teeth separate and disconnect the connection between the two transmission gears;

[0029] S3, after the two transmission gears are disconnected, the translational transmission gear is pushed by the meshing outer gear to rotate in the opposite direction, and the air bags on the wheel surfaces on both sides squeeze each other in the process, and spray high-speed airflow along the nozzle to the meshing point between the transmission gear and the outer gear of the cylinder;

[0030] S4. When the cylinder push rod pushes the plate frame to move horizontally, the push-pull block on the inner side of the through slot moves synchronously and pushes the pin head and the control pin to move axially along the inclined slot. At this time, the control pin automatically controls the ball column and continues to push the sleeve and the U-shaped frame to move after the transmission gear is disconnected. Finally, after the position is locked by the spring tooth, the cylinder push rod is pulled back to drive the control pin to reset. At this time, the two transmission gears are connected to each other.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] In the present invention, by pressing the control pin along the sleeve, the bar teeth in the bottom groove push the ball column to rotate, and drive the two slip rings to rotate in opposite directions along the cone mouth, so that the T-shaped teeth on the two slip rings are dislocated and unlocked, and then the inclined table pushes the ball column to move upward, and the top end of the ball column squeezes the two slip rings along the cone mouth to move in opposite directions. At this time, the T-shaped teeth separate and disconnect the connection between the two transmission gears. Compared with the existing method of directly pushing the intermediate gear in the meshing state, the above two transmission gears can be actively disconnected, so as to avoid the conflict between the rotation of the outer gear of the cylinder driven by the movement of the transmission gear and the rotation direction of the outer gear of the cylinder itself, so that the equipment does not need to be stopped to adjust the cylinder distance and then restarted, which optimizes the waste of machine start-up and stop time and increases production efficiency.

[0033] In the present invention, the translational transmission gear is pushed by the meshing outer gear of the cylinder to rotate in the opposite direction. The air bags on the wheel surfaces on both sides squeeze each other in the process, and high-speed airflow is sprayed along the nozzle toward the meshing point between the transmission gear and the outer gear of the cylinder, so that the meshing transmission area is automatically cleaned during the cylinder distance adjustment process. The use of automated air blowing reduces the frequency of manual inspection and cleaning, and improves the convenience of equipment use.

[0034] In the present invention, the push-pull block pushes the pin head and the control pin along the inclined groove to move axially. At this time, the control pin automatically controls the ball column and continues to push the sleeve and the U-shaped frame to move after the transmission gear is disconnected. Finally, after the position is locked by the spring tooth, the cylinder push rod is pulled back to drive the control pin to reset. At this time, the two transmission gears are connected to each other. Compared with the user manually operating the control pin, the above-mentioned plate frame can use the push-pull block to first automatically operate the control pin to complete the disconnection of the transmission gear, and then adjust the cylinder distance, so that the operator only needs to operate the cylinder push rod, which optimizes and reduces the specific operation steps and has better operation safety.

[0056] One end of the bottom groove 518 is set as an inclined platform 521 that matches the ball column 515. The control pin 517 is pressed into the sleeve 54. The bar teeth 519 in the bottom groove 518 push the ball column 515 to rotate, and drive the two slip rings 59 to rotate in opposite directions along the cone mouth 516, so that the T-shaped teeth 513 on the two slip rings 59 are dislocated and unlocked. Then the inclined platform 521 pushes the ball column 515 to move upward, and the top end of the ball column 515 squeezes the two slip rings 59 along the cone mouth 516 to move in opposite directions. At this time, the T-shaped teeth 513 separate and disconnect the connection between the two transmission gears 57.

The airbags 5221 on the wheel surfaces on both sides are squeezed against each other in this process, and high-speed airflow is ejected along the nozzle 5222 toward the meshing point between the transmission gear 57 and the outer cylinder gear 56.

[0060] An automatic unlocking component 5223 is provided on the plate frame 53 , the equipment frame 1 and the control pin 517 .

[0068] A method for operating a calender for glass production comprises the following steps:

[0069] S1. When adjusting the distance between the two calendering rollers 3, the cylinder push rod 52 is first used to push the plate frame 53 and the sleeve 54 to move, and the sleeve 54 uses the connecting rod 55 to push the two connecting shafts 4 and the calendering rollers 3 to move in opposite directions, so that the calendering distance is increased.

[0070] S2. Before adjusting the calendering cylinder pitch, the control pin 517 is pressed in along the sleeve 54, and the bar teeth 519 in the bottom groove 518 push the ball column 515 to rotate, and drive the two slip rings 59 to rotate in opposite directions along the cone mouth 516, so that the T-shaped teeth 513 on the two slip rings 59 are dislocated and unlocked, and then the inclined table 521 pushes the ball column 515 to move upward, and the top end of the ball column 515 squeezes the two slip rings 59 along the cone mouth 516 to move in opposite directions, and at this time the T-shaped teeth 513 separate and disconnect the connection between the two transmission gears 57.

[0071] S3. After the two transmission gears 57 are disconnected, the translational transmission gear 57 is pushed by the meshing outer gear 56 to rotate in the opposite direction. The air bags 5221 on the wheel surfaces on both sides squeeze each other in this process and eject high-speed airflow along the nozzle 5222 toward the meshing point between the transmission gear 57 and the outer gear 56.

[0072] S4. When the cylinder push rod 52 pushes the plate frame 53 to translate, the push-pull block 52238 on the inner side of the through slot 52235 moves synchronously, and pushes the pin head 52236 and the control pin 517 to move axially along the inclined slot 52237. At this time, the control pin 517 automatically controls the ball column 515, and after the transmission gear 57 is disconnected, it continues to push the sleeve 54 and the U-shaped frame 52231 to move. Finally, after the position is locked by the spring tooth 52233, the cylinder push rod 52 is pulled back to drive the control pin 517 to reset. At this time, the two transmission gears 57 are connected to each other.

[0073] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments.

7. A calender for glass production according to claim 3, characterized in that: The U-shaped frame (52231) is threadedly connected with an unlocking bolt that matches the clamping slot (52234).

8. The method for operating a calender for glass production according to claim 3, comprising the following steps: S1. When adjusting the distance between the two calendering rollers (3), the cylinder push rod (52) is first used to push the plate frame (53) and the sleeve (54) to move, and the sleeve (54) uses the connecting rod (55) to push the two connecting shafts (4) and the calendering rollers (3) to move in opposite directions, so that the calendering distance increases; S2. Before adjusting the calendering cylinder pitch, the control pin (517) is pressed in along the sleeve (54), and the bar-shaped teeth (519) in the bottom groove (518) push the ball column (515) to rotate, and drive the two slip rings (59) to rotate in opposite directions along the cone mouth (516), so that the T-shaped teeth (513) on the two slip rings (59) are dislocated and unlocked, and then the inclined platform (521) pushes the ball column (515) to move upward, and the top end of the ball column (515) squeezes the two slip rings (59) along the cone mouth (516) to move in opposite directions, and at this time, the T-shaped teeth (513) separate and disconnect the connection between the two transmission gears (57); S3, after the two transmission gears (57) are disconnected, the translationally moving transmission gear (57) is pushed by the meshing outer gear (56) to rotate in the opposite direction, and the air bags (5221) on the wheel surfaces on both sides are squeezed against each other in the process, and high-speed airflow is ejected along the nozzle (5222) toward the meshing point between the transmission gear (57) and the outer gear (56); S4. When the cylinder push rod (52) pushes the plate frame (53) to translate, the push-pull block (52238) inside the through slot (52235) moves synchronously and pushes the pin head (52236) and the control pin (517) to move axially along the inclined slot (52237). At this time, the control pin (517) automatically controls the ball column (515) and continues to push the sleeve (54) and the U-shaped frame (52231) to move after the transmission gear (57) is disconnected. Finally, after the position is locked by the spring locking teeth (52233), the cylinder push rod (52) is pulled back to drive the control pin (517) to reset. At this time, the two transmission gears (57) are connected to each other.
