This modular design can adjust the size, structure and function of the clamping frame as needed, increasing the flexibility and adaptability of the system.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The smart probes 20 can freely judge the bottle shape and whether the glass bottle has defects through image acquisition and analysis, and screen out qualified glass bottles for subsequent work. The smart probes 20 can also control the rotating block 3 to automatically position itself vertically above the bottle mouth of the glass bottle, which is convenient for subsequent clamping work and avoids the influence of misalignment of the bottle mouth.

A plurality of movable grooves 6 are provided at the bottom of the rotating block 3. The plurality of movable grooves 6 are distributed in a circular array around the elastic airbag 9. The plurality of movable grooves 6 are respectively slidably connected with a clamping frame 7, and a small push rod is fixedly connected to the inner wall of the movable groove 6 on the side of the clamping frame 7 away from the elastic airbag 9. The elastic airbag 9 is extended into the bottle mouth, and the small push rod pushes the clamping frame 7 to move in the direction close to the elastic airbag 9 to clamp the bottle mouth. The inflation tube 18 is connected to an external air pump to inflate the inflation hole 8. The gas enters the elastic airbag 9 through the inflation hole 8. The elastic airbag 9 expands to fix the glass bottle from the inside of the glass bottle mouth, and cooperates with the clamping frame 7 to clamp the glass bottle from the outside of the bottle mouth. This double fixing method greatly improves the stability of the bottle and prevents the bottle from falling off or being damaged due to vibration or tilting. The use of the elastic airbag 9 enables the equipment to flexibly adapt to bottle mouths of different sizes. When the airbag is inflated, it can automatically adjust according to the size of the bottle mouth, thereby providing clamping and fixing capabilities for different bottle mouth sizes, allowing the equipment to adapt to different types of glass bottles or cans, increasing the versatility of the equipment.

[0030] A clamping block is fixedly installed on the top of the main bracket 1. Multiple main brackets 1 can be assembled into an expandable clamping frame by connecting the external guide rail frame as needed. The clamping block on the top of the main bracket 1 is clamped to the guide rail frame, and the distance between two adjacent main brackets 1 is controlled to be the same, so as to achieve the purpose of clamping a row of glass bottles at one time. The size, structure and function of the clamping frame can be adjusted as needed to increase the flexibility and adaptability of the system. By bringing the main brackets 1 of the two clamping frames close to each other, the glass bottles can be converted from a single row to a double row of bottle mouths for stable clamping, effectively improving the efficiency of clamping, handling and production line operations.

[0031] The bottom of the main bracket 1 is fixedly connected to the bottom plate 10 through an electric push rod, and the side wall of the bottom plate 10 is fixedly connected to the pad 11 through an electric push rod. The pad 11 and the fixed block 2 are located on the same side of the main bracket 1, and the pad 11 is located below the fixed block 2. The top of the pad 11 is rotatably connected to the limit column 12, and the position of the bottom plate 10 and the pad 11 is adjusted by the electric push rod so that the limit column 12 is aligned with the center position of the bottom circle of the glass bottle. Then, the bottom plate 10 is driven to drive the pad 11 to move upward so that the limit column 12 contacts the bottom surface of the glass bottle, providing bottom support for the flat bottom surface of the glass, so that the glass The clamping of the glass bottle is safer and more stable, ensuring the stability of the glass bottle and preventing the bottle from tilting or shifting during the cleaning process, thereby improving the overall clamping accuracy and safety. The side wall of the main bracket 1 is rotatably connected to the first rotating brush 16, and the first rotating brush 16 is located on the same side as the fixed block 2. The first rotating brush 16 is located between the fixed block 2 and the pad 11. The first rotating brush 16 is controlled to rotate by the internal motor of the main bracket 1. The bottom of the first rotating brush 16 is slidably connected to the second rotating brush 17, and the bottom of the second rotating brush 17 contacts the top of the bottom plate 10.

[0032] The two sides of the main bracket 1 are fixedly connected with side frames 13 through electric push rods. The two side frames 13 are symmetrically distributed on both sides of the first rotating brush 16. A clearance groove 14 is provided on the side where the two side frames 13 are close to each other. A limiting component is provided in the clearance groove 14. The limiting component includes two roller frames 15. The two roller frames 15 are symmetrically distributed in the clearance groove 14 and are slidably connected to the clearance groove 14. The sides of the two roller frames 15 that are away from each other are fixedly connected to the inner wall of the clearance groove 14 with springs. The two roller frames 15 are rotatably connected with rollers respectively. The rollers of the roller frames 15 are made of elastic material. The two side frames 13 are close to each other until the rollers The wheel frame 15 contacts the glass bottle and causes the spring to be slightly compressed. The design of the spring can adapt to the rotation of glass bottles of different sizes, while ensuring that the glass bottle will not deflect or move during the cleaning process, preventing the bottle from becoming unstable or deviating due to vibration or rotation during the cleaning process, further enhancing the clamping stability and cleaning effect of the bottle. The rotating block 3 clamps the glass bottle and rotates. After the glass bottle rotates, the first rotating brush 16 and the second rotating brush 17 are controlled to rotate a certain angle, so that the first rotating brush 16 and the second rotating brush 17 can contact the surface of the glass bottle. In the process of the glass bottle following the rotation of the rotating block 3, the brush pair cleans the surface of the glass bottle.

[0033] A heat dissipation nozzle 19 is provided on the side wall of the main bracket 1. The heat dissipation nozzle 19 and the fixed block 2 are located on the same side of the main bracket 1. The heat dissipation nozzle 19 is connected to the external air supply equipment through a pipe, and can blow out cooling gas of appropriate temperature. The heat dissipation nozzle 19 corresponds to the first rotating brush 16. The heat dissipation nozzle 19 can rotate up and down. When the glass bottle is clamped and rotated, the heat dissipation nozzle 19 is controlled to continuously deflect up and down and spray cooling gas. In the process of clamping and rotating the glass bottle, the increase in temperature will cause uneven temperature on the surface or inside of the bottle, thereby affecting the stability or processing accuracy of the bottle. The heat dissipation nozzle 19 sprays cooling gas, which can effectively control the temperature of the surface of the glass bottle, so that the bottle remains stable during the rotation process, thereby avoiding deformation, cracks or other possible damage to the glass bottle caused by temperature difference. The heat dissipation nozzle 19 continuously deflects up and down, which helps to blow the cooling gas evenly to the part that needs heat dissipation, enhance the heat dissipation effect, and avoid local overheating.

[0034] In the present invention, several movable grooves 6 are provided around the inflation hole 8 inside the rotating block 3. Several clamping frames 7 are fixed inside the movable grooves 6 by small push rods. Several clamping frames 7 are distributed in an array with the inflation hole 8 as the center. The extension and contraction of the small push rod can control the several clamping frames 7 to move closer to or farther away from each other. Several rotatable intelligent probes 20 are installed at the bottom of the rotating block 3. Through image acquisition and analysis, the bottle type can be freely judged and defective glass bottles can be screened. The intelligent probe 20 can also control the rotating block 3 to automatically position itself to a position vertically above the mouth of the glass bottle, so as to facilitate clamping the mouth of the glass bottle. After the several clamping frames 7 have initially clamped the mouth of the glass bottle, the elastic airbag 9 has not expanded and just extends into the bottle mouth, and the top of the fixed block 2 An inflation tube 18 is inserted, and the inflation tube 18 corresponds to the position of the inflation hole 8. One end of the fixed block 2 is extended to connect to an external air pump. It is only necessary to inflate the elastic airbag 9 through the inflation tube 18 to expand the elastic airbag 9, fix the glass bottle from the inside of the glass bottle mouth, and cooperate with the clamping frame 7 to clamp from the outside of the bottle mouth, which can play a role in stable clamping. You can also assemble multiple main brackets 1 into a clamping frame with a guide rail frame as needed. It is only necessary to clamp the top clamping block of the main bracket 1 to the guide rail frame, and control the spacing between two adjacent main brackets 1 to be the same. A row of glass bottles can be quickly clamped at one time. By moving the main brackets 1 of the two clamping frames close to each other, the glass bottles can be converted from a single row to a double row for stable clamping of the bottle mouth.

[0035] After the bottle mouth is clamped, the electric push rod installed at the bottom of the main bracket 1 is controlled to extend, so that the bottom plate 10 reaches the bottom position of the glass bottle. The electric push rod inside the bottom plate 10 is then controlled to extend, so that the pad 11 and the limit column 12 connected to the top of the pad 11 are located at the center of the glass bottle surface. The corresponding electric push rod is then controlled to make the limit column 12 contact the bottom surface of the glass bottle, providing bottom support for the flat bottom surface of the glass, making the clamping of the glass bottle safer and more stable. The main bracket 1 is rotatably connected to the side facing the pad 11 with a first rotating brush 16. The bottom of the first rotating brush 16 is slidably connected to the second rotating brush 17, and the bottom of the second rotating brush 17 contacts the bottom plate 10.

[0036] After the bottom of the bottle is further supported by the limiting column 12, the two side frames 13 are controlled to approach each other. A clearance groove 14 is opened on the side where the side frames 13 approach each other. The inside of the clearance groove 14 is connected to the roller frame 15 through a spring. The roller of the roller frame 15 is made of elastic material. The side frames 13 approach each other until the roller frame 15 contacts the glass bottle and causes the spring to be slightly compressed, so that the side limit of the glass bottle cannot be deflected. At this time, the driving gear 5 is controlled to rotate, which can make the rotating block 3 clamp the glass bottle for rotation. The side and bottom surfaces of the glass bottle are supported by the rollers and the limiting column 12 respectively, and will not prevent rotation. Due to its ductility, the spring can adapt to the situation where there are slight defects and deformations in the bottle body without getting stuck, and the design of the spring can adapt to glasses of different sizes. The bottle rotates, and after the glass bottle rotates, the first rotating brush 16 and the second rotating brush 17 are controlled to rotate so that the brushes can contact the surface of the glass bottle and clean the surface of the glass bottle, so that the surface of the glass bottle is fully cleaned before entering the next process, which helps to improve the quality of the final product. A heat dissipation nozzle 19 is fixedly installed on the side of the main bracket 1 facing the fixed block 2. The heat dissipation nozzle 19 is connected to the external air supply equipment through a pipeline and can blow out cooling gas at a suitable temperature. The heat dissipation nozzle 19 corresponds to the first rotating brush 16 and can be deflected up and down. When the glass bottle is clamped and rotated, the heat dissipation nozzle 19 is controlled to continuously deflect up and down and spray cooling gas, which can not only improve the cleaning effect but also evenly cool the bottle body.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
