as shown in fig. 2, 3, 6, 7 and 8, the process of making the non-stick coating on the surface of the transparent glass baking tray by adopting the non-stick coating glass baking tray making method in the steps S1-S6 also specifically relates to the glass baking tray bottom polishing treatment device, the device comprises a belt conveyor 1 for conveying the glass baking tray, a centering guide mechanism 2, a polishing treatment mechanism 3 and an interception mechanism 4 for intercepting the glass baking tray are sequentially distributed and arranged on a rack of the belt conveyor 1 along the conveying direction of the rack, a bearing clamping mechanism 5 is further assembled on the rack of the belt conveyor 1, and the bearing clamping mechanism 5 is positioned right below the polishing treatment mechanism 3.

As shown in fig. 2, 3, 6 and 7, the centering guide mechanism 2 includes a spacing adjustment assembly 21 mounted on the frame of the belt conveyor 1 and two guide and conveying assemblies 22 mounted on the spacing adjustment assembly 21; the two guide and positive conveying components 22 are symmetrically arranged along the horizontal direction perpendicular to the conveying direction of the belt conveyor 1, and the interval adjusting component 21 is used for adjusting the relative interval between the two guide and positive conveying components 22; the passing clearance between the two guide conveying members 22 gradually decreases in the process of gradually approaching the sanding mechanism 3 in the conveying direction of the belt conveyor 1. The interval adjusting assembly 21 comprises a bidirectional adjusting screw rod 211 which is horizontally and rotatably arranged on the frame of the belt conveyor 1, hand wheels are fixed at two ends of the bidirectional adjusting screw rod 211, two thread sections of the bidirectional adjusting screw rod 211 are in one-to-one corresponding threaded connection with a stroke frame 212, a first guide rod 213 is horizontally welded on the stroke frame 212, and the first guide rod 213 is in sliding fit with the frame of the belt conveyor 1; the two guiding and conveying components 22 are correspondingly assembled at the top ends of the two travel frames 212 one by one, the guiding and conveying components 22 comprise a roller frame 221 welded at the top ends of the travel frames 212, three guiding and conveying rollers 222 are vertically arranged on the roller frame 221 in a rotating mode, the three guiding and conveying rollers 222 are distributed in a triangular mode, flexible guiding belts 223 are sleeved on the three guiding and conveying rollers 222 together, a motor can be arranged at the shaft end of one guiding and conveying roller 222, so that the flexible guiding belts 223 are driven to move through the motor, the motor is not shown in the drawing, bristles are attached to the surfaces of the flexible guiding belts 223, and accordingly the glass baking tray can be guided through the guiding gaps through the bristles in the movement process of the flexible guiding belts 223.

In the actual processing process, the interception mechanism 4 has two states of interception and avoidance, and is realized through the rotation of the corner motor 41, the rotation of the rotation shaft 42 driven by the corner motor 41 can enable the fixed plate 43 and the adjustable baffle plate assembly 44 to synchronously rotate along with the rotation, when the baffle plate 441 is in a vertical state, the interception state can be the interception state, when the baffle plate 441 rotates to an inclined upward position back to the frosting treatment mechanism 3, the interception state can be the avoidance state, the glass baking tray can be allowed to pass through when the interception state is the avoidance state, and the fact that the corner motor 41 is motor equipment provided with a fixed corner and is provided with a self-locking structure can be required to maintain the state through self-locking under the two states.
