Description

Technical Field

[0001] This invention relates to the field of packaging bag processing technology, specifically to a conveying device for packaging bag processing equipped with a pneumatic adjustment component. Background Technology

[0002] Packaging bags are bags used to package various items, making it convenient to transport and store goods during production and distribution. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags end up in landfills like ordinary garbage, with only 7% being recycled. During the processing of packaging bags, conveying equipment is needed to transport the packaging film so that it can be rolled up and used to make packaging bags.

[0003] However, existing packaging bag processing conveyor equipment does not have pneumatic adjustment components, which causes the packaging film to be too loose or too tight during the conveying and winding process. This directly leads to the packaging film not being able to be wound and wound well or even breaking directly, which affects the normal operation of the packaging bag conveyor equipment. Therefore, a packaging bag processing conveyor equipment with pneumatic adjustment components is proposed. Summary of the Invention

The vertical position of the piston rod is freely controlled, and the rotation angle of the push plate is freely controlled with the cooperation of the mounting plate, drive rod, and mounting groove. With the sliding assistance of the slide rail and moving slider, the height of the push frame and adjusting roller is controlled.

Conversely, when the packaging film is too loose, the adjusting roller is moved upwards to restore the packaging film to its optimal tension. The entire process is pneumatically controlled, and the first and second gas flow meters accurately calculate the inflation and deflation volumes. This not only precisely controls the tightness of the packaging film during transport but also provides a certain degree of flexibility and buffering, preventing the packaging film from tearing due to rigid direct adjustment, and facilitating better winding of the packaging film by the user.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] Please see Figure 1-7This invention provides a technical solution: a conveying device for processing packaging bags with a pneumatic adjustment component, comprising a first base 1 and a second base 2 located to the right of the first base 1.

Mounting plates 4 are symmetrically fixedly connected to the second base 2 along the front-back direction. Each mounting plate 4 has a placement groove 5, and a block 6 is engaged within the placement groove 5. A fixed shaft 7 is rotatably mounted on the side of the blocks 6 that is close to each other.

By setting the pneumatic adjustment component, the entire process is controlled by pneumatic means. The first gas flow meter 43 and the second gas flow meter 47 are used to accurately calculate the inflation and deflation volume. This not only accurately controls the tightness of the packaging bag film 10 during transportation, but also has a certain degree of flexibility and buffering force, avoiding the packaging bag film 10 from being torn by hard direct adjustment. This makes it easier for users to roll up the packaging bag film 10. A docking plate 3 is symmetrically fixedly connected to the opposite side of the first base 1 and the second base 2 along the front and back direction. A controller is fixedly connected to the front of the top of one set of docking plates 3 through the vertical plate.

[0026] Example 2

[0027] Please see Figure 1-7This invention provides a technical solution: a conveying device for processing packaging bags with a pneumatic adjustment component, comprising a first base 1 and a second base 2 located to the right of the first base 1. Supporting vertical plates 18 are symmetrically fixedly connected to the first base 1 along the front-back direction. Mounting plates 4 are symmetrically fixedly connected to the second base 2 along the front-back direction. Each mounting plate 4 has a placement groove 5, and a block 6 is engaged within the placement groove 5. A fixed shaft 7 is rotatably mounted on the side of the blocks 6 that is close to each other. A winding drum 9 is fixedly connected to the fixed shaft 7, and a packaging bag film 10 is wound on the winding drum 9. Electric slide rails 13 are fixedly connected to both sides of the top back of one set of mounting plates 4. A sliding seat 14 is provided within the electric slide rail 13, and a mounting plate 14 is fixedly connected to the side of the sliding seat 14 that is close to each other. Mounting sleeve 15, with motor 16 fixedly connected inside. The output shaft of motor 16 is fixedly connected to external spline shaft 17, with the end of external spline shaft 17 away from motor 16 inserted into fixed shaft 7. Each set of electric slide rails 13 has diagonal braces fixedly connected to both sides of its bottom back surface, with the end of the diagonal brace away from the electric slide rail 13 fixedly connected to one of the mounting plates 4. The diagonal brace design supports the electric slide rail 13, improving its stability. Limiting frames 8 are fixedly connected to the inner side of the surface of block 6, with the opposite sides of the limiting frames 8 attached to mounting plate 4. A support frame 19 is fixedly connected to the left side of the supporting vertical plate 18. Multiple sets of auxiliary shafts 20 are sequentially fixedly connected to the support frame 19 along the left-right direction. The number of auxiliary shafts 20 is at least three sets, and the overall structure of the multiple sets of auxiliary shafts 20 is V-shaped. The limitation on the number and shape of the auxiliary shafts 20 allows for better conveying of the packaging film 10. A guide cylinder 21 that works with the packaging film 10 is rotatably mounted on the auxiliary shaft 20. A U-shaped sliding frame 11 is horizontally inserted into the top of one side of the mounting plate 4. The right side of the U-shaped sliding frame 11 is inserted into the right side of the inner cavity of the placement groove 5. A limit bolt 12 is threadedly connected to the top right side of the mounting plate 4 through a limit nut, and the bottom end of the limit bolt 12 is attached to the bend of the U-shaped sliding frame 11. A fixing groove 49 that works with the U-shaped sliding frame 11 is opened on the left side of the inner cavity of the placement groove 5. By setting the U-shaped sliding frame 11, the block 6 is quickly limited to prevent the block 6 from falling off the mounting plate. The groove 5, with its threaded connection between the limiting nut and the limiting bolt 12, allows for the positioning of the U-shaped sliding frame 11, improving its limiting effect on the block 6. The design of the fixing groove 49 allows the U-shaped sliding frame 11 to be hidden when releasing its limiting effect on the block 6, preventing interference with the normal up-and-down movement of the block 6. A pneumatic adjustment assembly for use with the packaging film 10 is provided on one side of the supporting vertical plates 18 that are close to each other. The pneumatic adjustment assembly includes a strip-shaped hole 22 on one side of the supporting vertical plates 18 that is close to each other. A moving block 23 is slidably disposed within the strip-shaped hole 22. A connecting shaft 25 is fixedly connected to one side of the moving block 23 that is close to each other. An adjusting roller 26 for use with the packaging film 10 is fixedly connected to the connecting shaft 25.A pusher frame 27 is fixedly connected to the inner side of the bottom of the movable block 23, and the front and back of the pusher frame 27 are slidably disposed on the side of the supporting vertical plate 18 that are close to each other.

Positioning grooves 28 are provided on the right side of the bottom front of one set of supporting vertical plates 18 and the bottom of the left side of the bottom front of another set of supporting vertical plates 18. A pusher plate 29 is rotatably mounted within the positioning grooves 28, and one end of the pusher plate 29 is rotatably mounted on the movable slider 31. An installation groove 32 is provided at the other end of the pusher plate 29. The pneumatic adjustment assembly also includes an air pump 40 fixedly connected to the left side of the top front of the first base 1. The air outlet of the air pump 40 is connected to a main pipe 41. The front and back of the top of the first base 1 are... Multiple sets of fixed cylinders 33 are vertically embedded along the left-right direction on the back. A piston rod 34 is slidably arranged inside the fixed cylinder 33. The top of the piston rod 34 is fixedly connected to the mounting plate 35. A drive rod 36 is slidably arranged in each set of mounting slots 32, and both ends of the drive rod 36 are rotatably mounted on the mounting plate 35. The top and bottom of the fixed cylinders 33 are respectively connected to a first pipe 37 and a second pipe 38. Both ends of the main pipe 41 are connected to the second pipe 38. A branch pipe 42 is connected to the first pipe 37, and one end of the branch pipe 42 is connected to the main pipe 41. Both the first pipe 37 and the second pipe 38 are connected to exhaust pipes 39. Two sets of first solenoid valves 44 are arranged along the front-back direction on the main pipe 41. A second solenoid valve is arranged at the end of the branch pipe 42 near the main pipe 41. A second solenoid valve 45 is located above the first solenoid valve 44. A third solenoid valve 46 is installed on the exhaust pipe 39. Two sets of first gas flow meters 43 are installed on the main pipe 41, with the first gas flow meters 43 located above the second solenoid valve 45. A second gas flow meter 47 is installed on the exhaust pipe 39, located inside the third solenoid valve 46. By setting up a pneumatic adjustment component, the entire process is controlled pneumatically. The first gas flow meters 43 and the second gas flow meters 47 are used to accurately calculate the inflation and deflation volumes. This not only allows for precise control of the tightness of the packaging film 10 during transport but also provides a certain degree of flexibility and cushioning, preventing the packaging film 10 from tearing due to rigid direct adjustment, thus facilitating use. The packaging film 10 is wound up more effectively. One-way valves 48 are installed at the end of the main pipe 41 near the second pipe 38 and at the end of the branch pipe 42 near the first pipe 37. The one-way valves 48 are designed to allow gas to be quickly discharged through the exhaust pipe 39 without entering the main pipe 41 or the branch pipe 42. A mating plate 3 is symmetrically fixedly connected to the side of the first base 1 and the second base 2 that are close to each other along the front-back direction. A controller is fixedly connected to the top front of one set of mating plates 3 via a vertical plate. A positioning insert 24 is fixedly connected to the top of the inner cavity of the strip hole 22. The bottom of the positioning insert 24 passes through the moving block 23 and is fixedly connected to the bottom of the inner cavity of the strip hole 22. A support is fixedly connected to the main pipe 41, and the bottom of the support is fixedly connected to the first base 1.The design of the positioning plate 24 limits the movement of the moving block 23, improving its stability during movement. Furthermore, the design of the support component enhances the overall stability of the main pipe 41, preventing breakage.

[0028] Working principle: The user activates the air pump 40, the second solenoid valve 45, and the third solenoid valve 46 corresponding to the second pipe 38 via the controller. The air pump 40 then delivers gas through the main pipe 41 to the branch pipe 42, and then through the branch pipe 42 to the first pipe 37, finally reaching the top of the inner cavity of the fixed cylinder 33. As gas continuously fills the cylinder, it pushes the piston rod 34 downwards. The gas below the piston rod 34 is discharged through the exhaust pipe 39 connected to the second pipe 38. The first gas flow meter 43 and the second gas flow meter 47 monitor the intake and exhaust volumes in real time. The downward-moving piston rod 34, in cooperation with the mounting plate 35, drives the drive rod 36 downwards synchronously. At this time, the drive rod... The sliding connection between the drive rod 36 and the mounting groove 32 allows the drive rod 36 to move downwards, causing one end of the push plate 29 to swing downwards, while the other end swings upwards synchronously. With the sliding assistance of the slide rail 30 and the movable slider 31, the push frame 27, the movable block 23, and the adjusting roller 26 move upwards synchronously. The upward-moving adjusting roller 26 then moves the packaging film 10 upwards until it is pushed back from a loose state to a suitable tightness. At this point, the second solenoid valve 45 and the third solenoid valve 46 corresponding to the second pipe 38 are closed. If the packaging film 10 is too tight, the corresponding first solenoid valve 44 and the third solenoid valve 46 corresponding to the first pipe 37 are opened. The film is filled from the bottom of the fixed cylinder 33, driving the piston rod 34 to move upward, which in turn drives the adjusting roller 26 to move downward, quickly relieving the tension of the packaging film 10 and restoring it to its optimal tension. The entire process is pneumatically controlled, providing precise control over the tension of the packaging film 10 during transport while also offering flexibility and cushioning to prevent the film from tearing due to rigid direct adjustment. This allows for better winding of the packaging film 10. Simultaneously, the user activates the motor 16 via the controller. The motor 16 drives the external spline shaft 17 and the fixed shaft 7 to rotate synchronously, driving the winding drum 9 to continue winding the packaging film. The membrane 10 is wound up. After winding is complete, the user rotates the limiting bolt 12 to rotate and move upward within the limiting nut until the limiting bolt 12 disengages from the U-shaped sliding frame 11 and moves above the U-shaped sliding frame 11. Then, the user pulls one end of the U-shaped sliding frame 11 to one side until the other end of the U-shaped sliding frame 11 is hidden in the fixing groove 49. At this time, the user activates the electric slide rail 13 through the controller. The electric slide rail 13 drives the slide base 14, mounting sleeve 15, motor 16 and external spline shaft 17 to move backward until the external spline shaft 17 is completely disengaged from the fixing shaft 7. At this time, the user lifts the winding drum 9 upward to quickly disassemble the winding drum 9 after winding and replace it with a new winding drum 9.

[0029] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric slide rail 13, motor 16, air pump 40, controller, first solenoid valve 44, second solenoid valve 45, third solenoid valve 46, first gas flow meter 43 and second gas flow meter 47 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
