Technical Field

[0001] The invention relates to a glass edge grinding machine, in particular to a belt-type glass edge pressing mechanism and a method for pressing glass. Background Art

[0002] Glass edge grinding machine is a device used to chamfer the edge of glass. The existing technology often uses a clamping method in which a belt mechanism and a conveyor belt mechanism cooperate up and down to transport and fix the glass at the edge grinding station. Figure 7 As shown, the outer surface of the belt 4 of the traditional belt mechanism is flat. In the process of clamping the glass 7, the full width of the belt 4 is pressed against the glass 7. For the glass with a pre-protective film on the top surface, since the contact area between the belt 4 and the glass 7 is large, the area of ​​the pre-film on the glass 7 that is damaged is bound to be large, which can easily lead to unqualified glass processing. Summary of the invention

[0003] The present invention aims to improve the above-mentioned deficiencies of the existing belt-type glass edge pressing mechanism, and the technical solutions adopted are as follows:

[0004] A belt-type glass edge pressing mechanism comprises a lifting plate arranged vertically on a plate surface, the lifting plate is connected to a lifting mechanism for driving the lifting plate to move up and down, pulleys are arranged on the same side plate surface of the lifting plate at intervals in the horizontal direction, a belt is wound around each pulley, the bottom section of the belt is horizontally exposed below the lifting plate, an elastic pressing block is also arranged on the lifting plate, the elastic pressing block is located in a belt loop of the belt and the bottom surface of the elastic pressing block contacts the inner surface of the bottom section of the belt so as to provide downward pressure to the bottom section of the belt, a circle of bosses is circumferentially arranged on the outer surface of the belt, and a circle of narrow bosses is circumferentially arranged on the outer surface of the bosses for pressing the glass downward.

[0005] As a preferred solution, the boss is narrower than the belt and is flush with the belt and offset to the side of the outer surface of the belt close to the lifting plate.

[0006] As a preferred solution, the boss is an independent rubber piece and is glued and fixed on the belt.

[0007] As a preferred solution, the narrow protrusion is narrower than the boss and is flush with the side of the outer surface of the boss close to the lifting plate, so that the narrow protrusion is located below the positive projection of the lifting plate.

[0021] The present invention is described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-5The belt-type glass edge pressing mechanism shown in the figure comprises a lifting plate 1 vertically arranged on a plate surface, the lifting plate 1 is connected with a lifting mechanism 2 for driving the lifting plate 1 to move up and down, the lifting mechanism 2 comprises two sets of lifters 2.1, the two sets of lifters 2.1 are arranged outside the same side plate surface of the lifting plate 1 at a distance from each other in the horizontal direction, each set of lifters 2.1 comprises a support tube 2.11, a transmission box 2.12, a lifting rod 2.13 and a connection box 2.14, wherein: the support tube 2.11 is arranged upright 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 connected to the transmission box 2.12 for transmission and movement up and down, and the bottom is movably arranged on the lifting rod 2.13. In the support tube 2.11, the connecting box 2.14 is sleeved and fixed on the lifting rod 2.13 and fixedly connected to the lifting plate 1, so that the lifting plate 1 is transmission-connected to the two lifting rods 2.13; the lifting mechanism 2 also includes a synchronous shaft 2.2 and a driving motor 2.3, and the two ends of the synchronous shaft 2.2 are respectively transmission-connected to the two transmission boxes 2.12, and the driving motor 2.3 is fixedly installed on any transmission box 2.12 and transmission-connected to the transmission box 2.12; when working, 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, thereby driving the two connecting boxes 2.14 to rise and fall synchronously, and then driving the lateral ends of the lifting plate 1 to rise and fall synchronously.

[0023] Pulleys 3 are rotatably provided at both lateral ends of the lifting plate 1, and a belt 4 is wound between the pulleys 3 at both ends. The bottom section of the belt 4 is horizontally exposed below the lifting plate 1 so that the belt 4 can contact the glass through the outer surface of its bottom section. In order to provide downward pressure to the bottom section of the belt 4, a plurality of pressure block assemblies are arranged side by side along the bottom edge of the lifting plate 1. Each pressure block assembly includes a fixed seat arranged on the lifting plate 1 and an elastic pressure block 5 arranged at the bottom of the fixed seat. All the elastic pressure 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 circle of bosses 4.1 narrower than the belt 4 is provided on the outer surface of the belt 4, and a circle of narrow protrusions 4.11 narrower than the bosses 4.1 and used to press the glass downward is provided on the outer surface of the bosses 4.1, and the width of the narrow protrusions 4.11 is set at 2-8mm.

[0025] In order to reduce the difficulty of forming the belt 4, the boss 4.1 is set as an independent rubber part and is glued and fixed on the belt 4; in order to ensure the connection firmness and pressing stability of the narrow protrusion 4.11, the narrow protrusion 4.11 is set as a rubber part integrally formed with the boss 4.1.

[0026] In order to facilitate the narrow protrusion 4.11 to bear force, the boss 4.1 is arranged flush with the side of the outer surface of the belt 4 close to the lifting plate 1, and the narrow protrusion 4.11 is arranged flush with the side of the outer surface of the boss 4.1 close to the lifting plate 1, so that the narrow protrusion 4.11 is located below the positive 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 pressure block 5, a circle of guide grooves 4.2 are provided on the circumference of the inner surface of the belt 4, and the elastic pressure block 5 is slidably connected to the guide groove 4.2 through a guide block 5.1 protruding from its bottom surface; it should be particularly pointed out that the guide groove 4.2 needs to be arranged in the middle of the inner surface of the belt 4 to be away from the width sides of the belt 4. The purpose of this is to avoid setting the guide structure on the edge of the belt 4 that is easy to wear, resulting in the belt 4 being unable to 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 pressure block 5, a convex rib 5.2 parallel to the guide block 5.1 is further provided on the edge of the bottom surface of the elastic pressure block 5 away from the lifting plate 1, and a belt groove 5.3 is formed between the convex rib 5.2 and the guide block 5.1. Most of the bottom section of the belt 4 is slidably arranged in the belt groove 5.3 and is flush with the bottom surface of the elastic pressure block 5, and the boss 4.1 and the narrow convex block 4.11 are exposed from the bottom surface of the elastic pressure block 5.

[0029] In order to further improve the running stability of the belt 4 on the bottom surface of the elastic pressure block 5, a buckle plate 6 is provided on the elastic pressure block 5 for making the belt 4 fit the elastic pressure block 5. The buckle plate 6 is an L-shaped plate and one folded surface thereof is fixed to the side of the elastic pressure block 5 by screws as a connecting surface, and the other folded surface is horizontally arranged under the elastic pressure block 5 as a supporting surface and the belt 4 is lightly pressed into the belt groove 5.3. The boss 4.1 needs to be partially or completely exposed under the supporting surface of the buckle plate 6 so that the narrow protrusion 4.11 can be completely exposed under the supporting surface of the buckle plate 6.

[0030] The installation method of the above-mentioned belt-type glass edge pressing mechanism is as follows: two support tubes 2.11 are fixed to the same side of the support platform 8 of the glass edge grinding machine, so that the belt 4 is located directly above the support platform 8 and is vertically parallel to the conveyor belt 9 wound around the surface of the support platform 8, and the narrow protrusion 4.11 is located in a position where it can be directly opposite to the inner side of the edge grinding area 7.1 set at the upper edge of the glass 7.

[0031] like Figure 1 and 6As shown, the method of pressing the glass by the above-mentioned belt-type glass edge pressing mechanism 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, and the narrow protrusion 4.11 presses the inner area of ​​the edge grinding area 7.1 set on the top surface of the glass 7 adjacent to the upper edge of the glass, so as to press the edge of the glass against the conveyor belt 9 and the support platform 8, and the belt 4 cooperates with the conveyor belt 9 up and down to clamp the glass 7 and move it to the edge grinding station. During the above process, the belt 4 itself does not have a rotating power, but is driven by the conveyor belt 9 through the glass 7 and moves synchronously with the conveyor belt 9; because the narrow protrusion 4.11 avoids the edge grinding area 7.1, it will not hinder the edge grinding mechanism from chamfering the upper edge of the edge grinding area 7.1; because the narrow protrusion 4.11 is narrow and adjacent to the edge grinding area 7.1, the pre-filming area damaged by it can be limited to the damage range that is inevitably incidental to the processing and grinding area 7.1, so no additional pre-filming damage will occur.
