Description

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 belt mechanism and a conveyor belt mechanism to cooperate with each other to transport the glass and fix it in 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 glass with a pre-prepared 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-prepared film on the glass 7 is inevitably damaged. It is easy to cause 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 includes a lifting plate arranged vertically on the plate surface, the lifting plate is connected to a lifting mechanism for driving it to move up and down, pulleys are provided on the same side plate surface of the lifting plate at a laterally spaced interval, a belt is wound around each pulley, and the bottom section of the belt is horizontally exposed below the lifting plate, and an elastic pressure block is also provided on the lifting plate, the elastic pressure block is located in the belt loop and the bottom surface contacts the inner surface of the bottom section of the belt connected to provide downward pressure to the bottom section of the belt, a circle of bosses is provided on the outer surface of the belt, and a circle of narrow bosses is provided 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 and offset to the side of the outer surface of the boss close to the lifting plate, so that the narrow protrusion is located below the orthographic projection of the lifting plate.

[0008] As a preferred solution, the narrow bump and the boss are integrally formed rubber parts.

[0009] As a preferred solution, a guide groove is provided on the inner surface of the belt in a circumferential direction, and the elastic pressure block is slidably connected to the guide groove via a guide block protruding from the bottom surface of the elastic pressure block.

[0010] As a preferred solution, the guide groove is arranged in the middle of the inner surface of the belt to be away from both sides of the belt.

[0011] As a preferred solution, a convex rib parallel to the guide block is provided on the edge of the bottom surface of the elastic pressure block away from the lifting plate, and a belt groove is formed between the convex rib and the guide block. Most of the bottom section of the belt slides in the belt groove and is flush with the bottom surface of the elastic pressure block, and the boss and the narrow convex block are exposed on the bottom surface of the elastic pressure block.

[0021] The present invention will be described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-5The belt-type glass edge pressing mechanism shown in the figure includes a lifting plate 1 arranged vertically on the plate surface, the lifting plate 1 is connected to a lifting mechanism 2 for driving it to move up and down, the lifting mechanism 2 includes two sets of lifters 2.1, the two sets of lifters 2.1 are arranged horizontally and spaced apart outside the same side plate surface of the lifting plate 1, each set of lifters 2.1 includes 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 with its bottom 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 vertical movement, and the bottom is movably arranged on the lifting plate 2.14. Inside 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, thereby transmission connecting the lifting plate 1 to the two lifting rods 2.13; the lifting mechanism 2 also includes a synchronous shaft 2.2 and a drive 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 drive motor 2.3 is fixedly installed on any one of the transmission boxes 2.12 and transmission-connected to the transmission box 2.12; when working, the drive 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 number 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 provided on the lifting plate 1 and an elastic pressure block 5 provided 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 bumps 4.11 narrower than the bosses 4.1 and used to press the glass downward are provided on the outer surface of the bosses 4.1. The width of the narrow bumps 4.11 is set at 2-8 mm.

[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 force on the narrow protrusion 4.11, the protrusion 4.1 is offset and aligned on the side of the outer surface of the belt 4 close to the lifting plate 1, and the narrow protrusion 4.11 is offset and aligned on the side of the outer surface of the protrusion 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 grooves 4.2 through the guide blocks 5.1 protruding from its bottom surface; it should be pointed out in particular that the guide grooves 4.2 need 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 prone to wear, which will result 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 provided on the edge of the bottom surface of the elastic pressure block 5 away from the lifting plate 1. A belt groove 5.3 is formed between the convex rib 5.2 and the guide block 5.1. The bottom section of the belt 4 slides in the belt groove 5.3 and is flush with the bottom surface of the elastic pressure block 5. 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 belt-type glass edge pressing mechanism is installed as follows: the 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 that passes around the support platform 8, and the narrow protrusion 4.11 is positioned so that it is directly opposite 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 of 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 pressure block 5 to descend, and the narrow protrusion 4.11 presses on 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. The belt 4 and the conveyor belt 9 cooperate with each other 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 necessarily incidental to the processing and grinding area 7.1, so that no additional pre-filming damage will occur.
