[0002] In glass printing technology, patterned glass is made by calendering, which involves rolling patterns or designs onto the glass.

[0003] A search revealed a utility model patent with application number 202222098254.4, entitled "A Glass Printing Device for Glass Processing." This patented device uses a brush roller to scrape the glass surface repeatedly, which can remove dust from the glass surface, thereby effectively improving the quality of glass printing processing and preventing the printed glass from failing to meet the standards due to dust on the glass surface. This, in turn, improves the pass rate of glass printing processing to a certain extent.

[0004] However, this patented device may require maintenance due to wear and tear, leading to prolonged downtime of the production line and affecting the device's production efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a calendering roll with adjustable gap.

[0011] Preferably, the bottom of the lifting block is fixedly connected to a connecting plate aligned with the rotating block, the bottom of the connecting plate is fixedly connected to a baffle aligned with the circular block, the circumferential side of the rotating block is rotatably connected to the circumferential side of the baffle, and the circumferential side of the locking block abuts against the circumferential side of the baffle.

[0012] Preferably, at least two telescopic grooves are provided between the two sides of the lifting block and are misaligned with the rotating block. A telescopic block is slidably connected between the top inner wall and the bottom inner wall of the telescopic groove. The two ends of the telescopic block extend to the outside of the telescopic groove. One side of the telescopic block abuts against one side of the rotating block.

[0013] Preferably, the lifting block has a slot inside that is aligned with the telescopic block. A limiting post is fixedly connected between the inner walls of the two sides of the slot.

[0014] Compared with the prior art, this utility model provides a calendering roll with adjustable gap, which has the following beneficial effects:

[0015] The rotating block activates motor two, which drives the lead screw to rotate. The lead screw then moves the lifting block, which in turn moves the rotating block. The rotating block moves the circular block, which in turn moves the locking block, which in turn moves the roller shaft. This allows the device to adjust the gap between the two sets of roller shafts. This adjustment is beneficial for the device to control the distance between the roller shafts according to the processing needs of materials such as glass, ensuring uniform glass thickness and avoiding stress concentration or deformation caused by uneven thickness. Motor one then activates the rotating shaft, which in turn rotates the circular block, which in turn rotates the locking block, which in turn rotates the roller shaft. This allows the roller shaft to continuously print on the glass. Motor one is then activated for the roller shaft that has not yet been processed. Motor one rotates the circular block, which in turn moves the locking block to align with the notch in the rotating groove, moving the roller shaft and removing it from the notch. This allows the device to remove and repair roller shafts that have been in use for a period of time while ensuring continuous operation of the production line. This helps prevent prolonged downtime for maintenance due to wear and tear, which would otherwise affect the device's production efficiency. Attached Figure Description

[0023] A lifting groove 9, aligned with the rotating block 2, is provided between the two sides of the fixed plate 1. A motor 8 is fixedly connected to the top outer wall of the lifting groove 9. A lead screw 10 is fixedly connected to the output shaft of the motor 8. The other end of the lead screw 10 is rotatably connected to the bottom interior of the fixed plate 1.

[0024] The circumferential side of the lead screw 10 is threaded with at least two lifting blocks 11 aligned with the rotating block 2. One side of the lifting block 11 is slidably connected to the inner wall of the lifting groove 9. One end of the rotating block 2 is rotatably connected to the side of the lifting block 11. The bottom of the fixing plate 1 is fixedly connected to the bottom plate 14.

[0025] The bottom of the lifting block 11 is fixedly connected to a connecting plate 16 aligned with the rotating block 2. The bottom of the connecting plate 16 is fixedly connected to a baffle 15 aligned with the circular block 5. The circumferential side of the rotating block 2 is rotatably connected to the circumferential side of the baffle 15. The circumferential side of the locking block 4 abuts against the circumferential side of the baffle 15.

[0026] At least two telescopic grooves are provided between the two sides of the lifting block 11, which are misaligned with the rotating block 2. A telescopic block 12 is slidably connected between the top inner wall and the bottom inner wall of the telescopic groove. The two ends of the telescopic block 12 extend to the outside of the telescopic groove. One side of the telescopic block 12 abuts against one side of the rotating block 2.

This allows the device to adjust the gap between the two sets of rollers 3, which is beneficial for adjusting the distance between rollers 3 according to the processing needs of materials such as glass. This controls the glass thickness to ensure uniform thickness and avoids stress concentration or deformation caused by uneven thickness. Starting motor 7 drives rotating shaft 6 to rotate, which in turn rotates circular block 5. The circular block 5 drives the clamping block 4 to rotate, and the clamping block 4 drives the roller 3 to rotate, so that the roller 3 continuously prints on the glass. The motor 7 corresponding to the roller 3 that has not been processed is started. The motor 7 drives the circular block 5 to rotate, and the circular block 5 drives the clamping block 4 to align with the notch of the rotating groove, moving the roller 3 so that the roller 3 is removed from the notch of the rotating groove. This allows the device to remove other rollers 3 that have been working for a period of time for maintenance while ensuring the continuous operation of the production line. This helps to prevent the production line from being shut down for a long time for maintenance due to wear and tear, which would affect the production efficiency of the device.
