[0021] The present application will be described below in conjunction with the drawings and specific embodiments.

[0022] As Figures 1-5The illustrated one kind of belt type glass device includes the vertical setting of the plate surface lifting plate 1, lifting plate 1 is connected with the lifting mechanism 2 for driving its up-down movement, lifting mechanism 2 includes two sets of lifter 2.1, two sets of lifter 2.1 are laterally apart from the same side plate surface outside lifting plate 1, each set of lifter 2.1 includes a support tube 2.11, a transmission box 2.12, a lifting rod 2.13 and a connecting box 2.14, wherein: the support tube 2.11 is vertically arranged and the bottom is exposed below the lifting plate 2.1, the transmission box 2.12 is fixedly arranged on the top of the support tube 2.1, the top of the lifting rod 2.13 is drivingly connected to the transmission box 2.12, the bottom is movably arranged in the support tube 2.11, the connecting box 2.14 is sleeved and fixed to the lifting rod 2.13 and is fixedly connected to the lifting plate 1, so that the lifting plate 1 is drivingly connected to the two lifting rods 2.13; the lifting mechanism 2 further includes a synchronous shaft 2.2 and a driving motor 2.3, the two ends of the synchronous shaft 2.2 are drivingly connected to the two transmission boxes 2.12, and the driving motor 2.3 is fixedly installed on any transmission box 2.12 and is drivingly connected to the transmission box 2.12; during operation, the driving motor 2.3 can drive the two lifting rods 2.13 to move up and down synchronously through the two transmission boxes 2.12, so as to drive the two connecting boxes 2.14 to move up and down synchronously, and further drive the two ends of the lifting plate 1 to move up and down synchronously.

[0023] The lateral ends of the lifting plate 1 are rotatably provided with pulleys 3, and a belt 4 is wound between the pulleys 3 at the two ends. The bottom section of the belt 4 is exposed below the lifting plate 1 to enable the belt 4 to contact the glass through the outer surface of the bottom section. In order to provide downward pressure to the bottom section of the belt 4, a plurality of pressing block assemblies are arranged side by side along the bottom edge of the lifting plate 1. Each pressing block assembly includes a fixed seat arranged on the lifting plate 1 and an elastic pressing block 5 arranged at the bottom of the fixed seat. All the elastic pressing blocks 5 are connected to the inner surface of the bottom section of the belt 4 through their respective bottom surfaces.

[0024] In order to reduce the contact area between the belt 4 and the top surface of the glass, a protrusion 4.1 narrower than the belt 4 is arranged on the outer surface of the belt 4 in a circumferential direction. A narrow protruding block 4.11, which is narrower than the protrusion 4.1 and used to press the glass downward, is arranged on the outer surface of the protrusion 4.1 in a circumferential direction. The width of the narrow protruding block 4.11 is set to be 2-8 mm.

[0025] In order to reduce the difficulty of forming the belt 4, the protrusion 4.1 is arranged as an independent rubber part and is fixedly attached to the belt 4. In order to ensure the connection stability and pressing stability of the narrow protruding block 4.11, the narrow protruding block 4.11 is arranged as a rubber part integrally formed with the protrusion 4.1.

[0026] In order to facilitate the force bearing of the narrow protrusion 4.11, the protrusion 4.1 is arranged on the outer surface of the belt 4 and is offset to the side of the lifting plate 1, and the narrow protrusion 4.11 is arranged on the outer surface of the protrusion 4.1 and is offset to the side of the lifting plate 1, so that the narrow protrusion 4.11 is located below the orthographic projection of the lifting plate 1.

[0027] In order to improve the running stability of the belt 4 on the bottom surface of the elastic pressing block 5, a guide groove 4.2 is arranged on the inner surface of the belt 4 in the circumferential direction, and the elastic pressing block 5 is slidably connected to the guide groove 4.2 through the guide block 5.1 protruding from the bottom surface of the elastic pressing block 5. It should be particularly pointed out that the guide groove 4.2 should be arranged in the middle of the inner surface of the belt 4 to be away from the two sides in the width direction of the belt 4. The purpose of this is to avoid arranging the guide structure on the edge of the belt 4 which is prone to wear, so that the belt 4 cannot run smoothly after the guide structure is worn.

[0028] In order to further improve the running stability of the belt 4 on the bottom surface of the elastic pressing block 5, a protruding rib 5.2 parallel to the guide block 5.1 is arranged on the side edge of the bottom surface of the elastic pressing block 5 away from the lifting plate 1. The protruding rib 5.2 and the guide block 5.1 are separated by a belt groove 5.3, and the bottom section of the belt 4 in the width direction is slidably arranged in the belt groove 5.3 and is flush with the bottom surface of the elastic pressing block 5. The protrusion 4.1 and the narrow protrusion 4.11 are exposed from the bottom surface of the elastic pressing block 5.

[0029] In order to further improve the running stability of the belt 4 on the bottom surface of the elastic pressing block 5, a buckle plate 6 for making the belt 4 adhere to the elastic pressing block 5 is further arranged on the elastic pressing block 5. The buckle plate 6 is an L-shaped plate, one fold surface of which is fixed to the side of the elastic pressing block 5 as a connecting surface through screws, and the other fold surface is arranged horizontally below the elastic pressing block 5 as a supporting surface and lightly presses the belt 4 in the belt groove 5.3. The protrusion 4.1 needs to be partially or completely exposed below the supporting surface of the buckle plate 6, so that the narrow protrusion 4.11 can be completely exposed below the supporting surface of the buckle plate 6.

[0030] The installation method of the above-mentioned belt type glass edge pressing device is as follows: two support pipes 2.11 are fixed to the same side of the support table 8 of the glass edging machine, so that the belt 4 is located directly above the support table 8 and is parallel to the conveying belt 9 around the support table 8, and the narrow protrusion 4.11 is located in a position that is vertically opposite to the inner side of the edging area 7.1 set on the upper edge of the glass 7.

[0031] As Figure 1 and 6The method for pressing the glass of the above-mentioned belt type glass pressing device is as follows: the lifting mechanism 2 drives the lifting plate 1, the pulley 3, the belt 4 and the elastic pressing block 5 to descend, the narrow protrusion 4.11 presses the inner side area of the edging area 7.1 of the glass 7 top surface close to the upper edge of the glass, so as to press the edge of the glass to the conveying belt 9 and the support table 8, the belt 4 is matched with the conveying belt 9 up and down, the glass 7 is clamped and moved to the edging position, in the above process, the belt 4 does not have rotating power by itself, but is driven by the conveying belt 9 through the glass 7 to move synchronously with the conveying belt 9; since the narrow protrusion 4.11 avoids the edging area 7.1, it will not hinder the edging mechanism to chamfer the upper edge of the edging area 7.1; since the narrow protrusion 4.11 is narrow and adjacent to the edging area 7.1, the pre-sticking film area pressed by the narrow protrusion 4.11 is in the damage range necessarily accompanied by the processing and polishing area 7.1, so that no additional pre-sticking film damage is caused.
