A label printing clamp for glass bottles based on adsorption engagement

Abstract

This utility model relates to the field of glass bottle printing fixture technology, specifically disclosing a glass bottle outer label printing fixture based on adsorption and clamping. It includes a mounting plate, on the outer surface of which a first electric push rod is fixedly mounted. The mounting plate is connected to the rotating shaft of a printing press. This glass bottle outer label printing fixture based on adsorption and clamping allows the glass bottle to be inserted into the upright and the first electric push rod to be activated. The push rod pulls a sliding rod, which in turn moves a guide head and expands a tab. This expander rotates and rests against the inner wall of the glass bottle, allowing the anti-slip pad to fit tightly against the inner surface of the bottle. The expansion angle of the tab can be adjusted to clamp and fix glass bottle openings of different diameters, ensuring that the outer surface of the glass bottle is fully exposed during printing. This facilitates the printing press in printing patterns and information onto the outer surface of the glass bottle without obstruction by clamps or other objects, greatly improving the convenience of the printing process.

Description

Technical Field

[0001] This utility model relates to the field of glass bottle printing fixture technology, specifically a glass bottle outer label printing fixture based on adsorption and clamping. Background Technology

[0002] Glass is a special material existing in a state between crystalline and liquid. It is made by supercooling a melt and has a structure characterized by short-range order and long-range disorder. Its optical properties include transparency and gloss, high heat resistance, and a low coefficient of thermal expansion. It also provides complete barrier properties against gases, liquids, and solvents. Broken glass can be recycled and melted to remanufacture glass products. With the production and creation of various solutions, containers are needed for holding them, and glass bottles are a good and stable type of container. In order to distinguish and check the liquid contained in a glass bottle, information labels about the contents need to be printed on the outer surface of the glass bottle to identify the type of solution inside. However, in the current glass bottle products, the clamps generally clamp and fix the outside of the bottle, which means that the label information cannot be printed over a large area on the outside of the glass bottle, making the printing process inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a glass bottle outer label printing fixture based on adsorption and clamping, so as to solve the problem mentioned in the background art that the fixture is located on the outside of the glass bottle and it is inconvenient to print on a large area.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a glass bottle outer label printing fixture based on adsorption and engagement, comprising a mounting plate, a first electric push rod fixedly mounted on the outer surface of the mounting plate, the output end of the first electric push rod passing through the mounting plate, the mounting plate being connected to the rotating shaft of a printing machine, and the mounting plate and the rotating shaft of the printing machine being concentrically designed, a second electric push rod fixedly mounted on the outer surface of the end of the first electric push rod away from the mounting plate, and the second electric push rod, the first electric push rod and the mounting plate being concentrically designed, a vertical rod threadedly mounted on the outer surface of the mounting plate, and a sliding rod slidably inserted inside the vertical rod, and the sliding rod being connected to the output end of the first electric push rod, an expansion piece rotatably mounted on the end of the vertical rod away from the mounting plate, a guide head engaging with the outer surface of the sliding rod, and the guide head and the sliding rod being fixed by screws, the guide head being wedge-shaped, and the outer surface of the guide head fitting against the outer surface of the expansion piece, and an elastic ring engaging with the outer surface of the expansion piece.

[0005] Preferably, an anti-slip pad is inserted and installed on the outer surface of the expansion piece, and the anti-slip pad engages with the expansion piece. The expansion piece is lower than the outer surface of the anti-slip pad, and the anti-slip pad is designed with an inclination. The opening of the anti-slip pad slot on the outer surface of the expansion piece faces upward.

[0006] By adopting the above technical solution, the anti-slip performance during use can be improved by using the anti-slip pad, and the expansion plate can be prevented from scratching the inner surface of the glass bottle. At the same time, the slot opening of the anti-slip pad on the expansion plate faces upward, which can further reduce the chance of the anti-slip pad falling off, and greatly reduce the chance of glass bottle damage during printing.

[0007] Preferably, the side of the upright near the mounting plate is hexagonal, a first sealing ring is fitted inside the upright, the outer surface of the first sealing ring is tightly fitted with the outer surface of the sliding rod, and the sliding rod and the first sealing ring are slidably connected.

[0008] By adopting the above technical solution, the hexagonal design of the upright allows it to be easily installed and fixed on the outer surface of the mounting plate, and the use of the first sealing ring ensures the sealing between the upright and the sliding rod and facilitates installation.

[0009] Preferably, a sealing plug is slidably mounted on the outer surface of the upright, and a second sealing ring is fixedly mounted inside the sealing plug, and the second sealing ring is in tight frictional connection with the upright. The sealing plug is a pagoda-shaped design.

[0010] By adopting the above technical solution, the sealing of the top stopper and the pagoda-shaped design, as well as the use of the second sealing ring, can ensure the sealing between the top stopper and the sliding rod, allowing the clamp to tighten and seal the mouth of different glass bottles.

[0011] Preferably, the outer surface of the sealing top plug is chamfered, and an air intake chamber is designed through the outer surface of the sealing top plug. An air tube is inserted into the side of the air intake chamber near the mounting plate. Through holes are opened on both outer surfaces of the mounting plate, and the air tube passes through the through holes of the mounting plate. A pressure detection sensor is fixedly installed on one side of the mounting plate and is connected to the air tube of the air intake chamber. The pressure detection sensor is connected to the air pump.

[0012] By adopting the above technical solution, the chamfer on the outer surface of the sealing cap makes it easier to insert the sealing cap into the mouth of the glass bottle, reducing the risk of the sealing cap failing to be inserted due to misalignment. Furthermore, the suction chamber can extract gas from inside the bottle, and the pressure inside the glass bottle can be monitored by the extracted gas and a pressure sensor to ensure the bottle is properly clamped. Monitoring the pressure inside the glass bottle further enhances the stability and intelligence of the clamped glass bottle.

[0013] Preferably, a connecting plate is fixedly installed at the output end of the second electric actuator, and guide rods are fixedly installed on the outer surface of the connecting plate, and another guide rod is slidably inserted into the outer surface of the mounting plate, and the guide rod is fixedly connected to the sealing top plug.

[0014] By adopting the above technical solution, the force after the second electric push rod is pushed out can be evenly distributed through the connecting plate, allowing the sealing top stopper to move horizontally so that the sealing top stopper can completely fit with the bottle mouth, preventing the glass bottle from leaking air due to the positional displacement of the sealing top stopper.

[0015] Preferably, a sleeve is inserted and installed on the outer surface of the guide rod, and locking nuts are threaded on both ends of the sleeve, with the outer surface of the locking nuts fitting against the outer surface of the sleeve. An annular protrusion is provided on the outer surface of the guide rod, and the annular protrusion of the guide rod engages with the inner surface of the sleeve.

[0016] By adopting the above technical solution, the length between the guide rods can be fixed by rotating the locking nut and the sleeve. The engagement of the guide thread annular protrusion with the sleeve further enhances the firmness between the sleeve and the guide rod after the locking nut is tightened. This allows the height of the sealing plug on the upright to be adjusted at will to adapt to the distance between the bottle neck and the bottle body of different glass bottles. When dealing with glass bottles of different sizes, the expansion piece can be inserted into the transition between the bottle neck and the bottle body, and the sealing plug seals the glass bottle neck, further improving the convenience and flexibility of use.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the glass bottle outer label printing fixture based on adsorption and clamping:

[0018] 1. In use, simply insert the glass bottle into the upright and start the first electric push rod. The first electric push rod will pull the sliding rod, which will drive the guide head to move and expand the expansion plate. The expansion plate can rotate and move against the inner wall of the glass bottle, allowing the anti-slip pad to fit tightly against the inner surface of the glass bottle. The expansion angle of the expansion plate can clamp and fix glass bottle mouths of different diameters, so that the outer surface of the glass bottle can be fully exposed during printing. This makes it convenient for the printing machine to print patterns and information on the outer surface of the glass bottle without being blocked by clamps or other objects, greatly improving the convenience of printing.

[0019] 2. After the expansion plate is inserted into the glass bottle and expands, the second electric push rod will retract and pull the sealing top stopper towards the bottle opening, so that the sealing top stopper can press against and be inserted into the glass bottle. Through the pressing of the sealing top stopper and the conical shape formed after the expansion plate rotates, the gas is drawn out of the glass bottle by the suction chamber, so that the glass bottle can automatically align with the center and be firmly fixed after being clamped and fixed. At the same time, the pressure obtained by suction is used to monitor whether the clamping position of the glass bottle is correct, so that the glass bottle will not be affected by the offset when printing the pattern, which will affect the printing quality or cause printing failure.

[0020] 3. When dealing with glass bottles of different sizes, first loosen the sleeve and locking nut according to the size of the glass bottle. This allows the guide rod to loosen and the distance to be quickly adjusted. Then, tighten the locking nut so that both ends of the sleeve can grip the guide rod. This allows the position of the sealing plug on the upright to be adjusted, thereby adjusting the distance between the sealing plug and the expansion plate. This allows glass bottles with different neck lengths and sizes to be clamped and fixed. The pagoda-shaped and chamfered design of the sealing plug allows glass bottles of different sizes to be clamped, improving the flexibility of the clamp during use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6This utility model provides a technical solution: a glass bottle outer label printing fixture based on adsorption and clamping, including a mounting plate 1. A first electric actuator 2 is fixedly mounted on the outer surface of the mounting plate 1, and the output end of the first electric actuator 2 passes through the mounting plate 1. The mounting plate 1 is connected to the rotating shaft of the printing machine, and the mounting plate 1 and the rotating shaft of the printing machine are concentrically designed. A second electric actuator 12 is fixedly mounted on the outer surface of the end of the first electric actuator 2 away from the mounting plate 1, and the second electric actuator 12, the first electric actuator 2, and the mounting plate 1 are concentrically designed. A vertical rod 3 is threadedly mounted on the outer surface of the mounting plate 1, and a sliding rod 5 is slidably inserted inside the vertical rod 3. Furthermore, the sliding rod 5 is connected to the output end of the first electric push rod 2, and the end of the upright rod 3 away from the mounting plate 1 is rotatably mounted with an expansion plate 7. The outer surface of the sliding rod 5 is fitted with a guide head 6, and the guide head 6 is fixed to the sliding rod 5 with screws. The guide head 6 has a wedge-shaped design, and the outer surface of the guide head 6 is in contact with the outer surface of the expansion plate 7. The outer surface of the expansion plate 7 is fitted with an elastic ring 17, and the outer surface of the expansion plate 7 is inserted with an anti-slip pad 8, and the anti-slip pad 8 is fitted with the expansion plate 7. The expansion plate 7 is lower than the outer surface of the anti-slip pad 8, and the anti-slip pad 8 has an inclined design. The slot opening of the anti-slip pad 8 on the outer surface of the expansion plate 7 faces upward.

[0030] Firstly, when printing on glass bottles, simply take the glass bottle and insert it into the inside of the upright rod 3, and limit its position using the sealing top plug head 9. Then, the retraction of the first electric push rod 2 drives the sliding rod 5 and the guide head 6 to move, allowing the guide head 6 to push open the expansion plate 7 and deform the elastic ring 17, so that the anti-slip pad 8 can come against the inner surface of the glass bottle to clamp glass bottles with different bottle mouth diameters. The anti-slip pad 8 can be stuck between the bottle body and the bottle neck. In conjunction with the retraction of the second electric push rod 12, the connecting plate 13 moves, allowing the guide rod 14 to push the sealing top plug head 9 to move, so that the sealing top plug head 9 can clamp the glass bottle with the opened expansion plate 7. During printing, the glass bottle can be rotated quantitatively by the rotating shaft of the printing machine to drive the mounting plate 1. At the same time, there are no obstructions around the glass bottle during printing, which greatly improves the convenience and operability of printing, and makes it easy to pick up and place the glass bottle.

[0031] The upright 3 has a hexagonal design on the side near the mounting plate 1. A first sealing ring 4 is fitted inside the upright 3, and the outer surface of the first sealing ring 4 is tightly fitted with the outer surface of the sliding rod 5. The sliding rod 5 and the first sealing ring 4 are slidably connected. A sealing plug 9 is slidably installed on the outer surface of the upright 3, and a second sealing ring 10 is fixedly installed inside the sealing plug 9. The second sealing ring 10 is tightly frictionally connected to the upright 3. The sealing plug 9 has a pagoda-shaped design, and the outer surface of the sealing plug 9 has a chamfered design. An air intake chamber 11 is designed through the outer surface of the sealing plug 9, and an air tube is inserted into the side of the air intake chamber 11 near the mounting plate 1. Through holes are opened on both sides of the outer surface of the mounting plate 1, and the air tube passes through the through holes of the mounting plate 1. A pressure detection sensor 18 is fixedly installed on one side of the mounting plate 1, and the pressure detection sensor 18 is connected to the air tube of the air intake chamber 11. The pressure detection sensor 18 is connected to the air pump.

[0032] Secondly, the pagoda-shaped design and chamfered design of the sealing top plug 9 allow it to be firmly inserted into the mouth of the glass bottle. The clamping between the sealing top plug 9 and the expansion plate 7 enables the glass bottle to automatically align itself and ensure concentricity with the upright rod 3. The use of the first sealing ring 4 and the second sealing ring 10 ensures that the suction chamber 11 remains sealed when extracting gas from the glass bottle. This allows the air pressure sensor 18 to monitor whether the glass bottle and the clamp are clamped and fixed in place by the pressure during suction, further improving the accuracy and convenience of the clamp when gripping the glass bottle and greatly enhancing the practicality of the clamp.

[0033] The output end of the second electric actuator 12 is fixedly installed with a connecting plate 13, and a guide rod 14 is fixedly installed on the outer surface of the connecting plate 13. Another guide rod 14 is slidably inserted into the outer surface of the mounting plate 1. The guide rod 14 is fixedly connected to the sealing top plug 9. A sleeve 15 is inserted into the outer surface of the guide rod 14. Locking nuts 16 are threaded on both ends of the sleeve 15, and the outer surface of the locking nut 16 is in contact with the outer surface of the sleeve 15. The outer surface of the guide rod 14 is provided with an annular protrusion, and the annular protrusion of the guide rod 14 is engaged with the inner surface of the sleeve 15.

[0034] Furthermore, when clamping glass bottles of different sizes and lengths, the distance between the guide rods 14 needs to be adjusted according to the length of the glass bottle neck. This allows the length of the guide rods 14 to be extended or shortened. The sleeve 15 can be deformed by tightening the locking nut 16 to hold and fix the guide rod 14, so that the position of the sealing top plug 9 on the upright rod 3 can be adjusted. This allows glass bottles of different sizes to be clamped and fixed, greatly improving the convenience and flexibility of the clamp during use.

[0035] Working principle: During printing, simply insert the glass bottle into the upright 3 and make it contact the sealing plug head 9. Then, activate the first electric push rod 2 to move the sliding rod 5 and the guide head 6 together, allowing the guide head 6 to expand the expansion plate 7. This allows the second electric push rod 12 to retract and move the connecting plate 13, enabling the guide rod 14 to push the sealing plug head 9 to move. With the expansion plate 7 and the anti-slip pad 8 in use, the glass bottle can be clamped and automatically aligned. Then, the air pump and suction chamber 11 extract the gas from the glass bottle. At the same time, the air pressure detection sensor 18 monitors the air pressure inside the glass bottle, allowing it to be detected if the glass bottle is not aligned and leaks air. This ensures the accuracy of the glass bottle's position after being clamped by the fixture. Finally, the rotation of the printing press shaft drives the mounting plate 1 to rotate precisely, allowing the printing press to print on the glass bottle, greatly improving the convenience and reliability of the printing process.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
