Description

Technical Field

[0001] The present invention relates to the field of material suction equipment components, and particularly to a material suction mechanism of a vacuum feeding machine. Background Art

[0002] A vacuum feeding machine is a dust-free closed pipeline conveying equipment that uses vacuum suction to convey granular and powdered materials. By using the air pressure difference between the vacuum and the ambient space, gas flow is formed in the pipeline to drive the powdered materials to move, thereby completing the conveying of powders.

[0003] The patent document with the publication number CN111115273A discloses a suction gun mechanism of a vacuum feeding machine for conveying powders, including a suction gun head. On both sides of the bottom of the suction gun head, there are air delivery pipes. At the top and bottom of the side of the air delivery pipe, air guide pipes are connected, and the top of the air guide pipe is connected to an air inlet pipe. The end of the air inlet pipe away from the air guide pipe is connected to an inflation device. On both sides of the inner cavity of the air delivery pipe, sealing blocks are movably sleeved, and through grooves are opened on both sides of the sealing blocks. A linkage shaft is movably sleeved between the two sealing blocks. For this suction gun mechanism of the vacuum feeding machine for conveying powders, through the design of the air delivery pipes on both sides of the suction gun head, air is continuously introduced into the upper and lower inner cavities of the air delivery pipe through the air inlet pipe and the air guide pipe, so that the moving block drives the sliding plate to reciprocate up and down, compressing and relaxing the spring, and using the spring to filter and shear the agglomerated materials to prevent the agglomerated materials from blocking between the suction gun and the pipeline of the vacuum feeding machine, ensuring the continuous and efficient material feeding of the vacuum feeding machine.

[0014] As a further solution of the invention, a limiting snap ring is fixedly sleeved on the lower part of the transmission rotating cylinder.

The upper end of the support clamping plate is slidably connected to the L-shaped frame.

[0020] Advantages of the present invention:

[0021] (1) When it is necessary to perform vacuum feeding on the powder material, the whole device is installed on the upper middle part of the box body containing the powder material through the support frame. The telescopic plate is telescoped to adapt to different widths of the powder material box bodies. Subsequently, the height of the telescopic cylinder is adjusted up and down so that the lower end of the telescopic cylinder is buried in the powder material, and at the same time, the upper part of the telescopic cylinder is exposed outside the powder material. Subsequently, the nozzle of the suction pipe of the vacuum feeder is docked with the limiting cylinder, and the vacuum feeder is started. Through the suction of the vacuum feeder and the feeding through the telescopic cylinder, the suction cylinder and the limiting cylinder, the powder material is sucked and fed. At the same time, the driving motor is started, and the driving rod is rotated through the driving motor. The driving rod pushes the suction cylinder to rotate around the driving motor. At the same time, the limiting ring limits the limiting cylinder, and thus limits the suction cylinder to prevent the limiting cylinder from rotating along with the rapid rotation of the suction cylinder, avoiding safety accidents. At the same time, the suction cylinder pushes the telescopic cylinder to rotate, and the lower part of the telescopic cylinder continuously stirs the powder material, thereby facilitating suction and keeping the powder material continuously sucked. As the powder material is continuously sucked, the telescopic cylinder continuously moves downward, keeping the lower half of the telescopic cylinder buried in the powder material, thereby maintaining the absorption efficiency of the powder material and preventing the interruption of powder material transportation, so as to quickly and fully suck the powder material in the box body into the vacuum feeder for feeding;

[0022] (2) The sealing ring enables the telescopic cylinder to maintain a seal when moving up and down on the outer periphery of the material suction cylinder, preventing air leakage and ensuring stable working efficiency. The support ring further maintains the sealed socket connection between the material suction cylinder and the telescopic cylinder to prevent air leakage. The first strip limits the support ring, thereby preventing the telescopic cylinder from rotating with the driving rotating cylinder due to the rapid rotation of the crushing motor, further ensuring the steady improvement of working efficiency. The support clamping plate and the support clamping column are clamped on the inner and outer sides of the upper end of the box body side wall. The support clamping plate is pushed by the limit bolt to keep the support clamping plate and the support clamping column in stable clamping. The support seat is rotatably connected to the support frame, thus being applicable to box bodies of different shapes and expanding the scope of application;

[0023] (3) The two electric push rods synchronously extend and retract to push the transmission plate, and the transmission plate pushes the telescopic cylinder, so that the lower half of the telescopic cylinder remains buried in the powder material to ensure the working efficiency when absorbing the powder material. The crushing motor rotates the transmission rod, the transmission rod drives the driving rotating cylinder to rotate, the driving rotating cylinder drives the first crushing rod to rotate, and at the same time, the driving rotating cylinder moves synchronously with the movement of the telescopic cylinder. When the lower end of the telescopic cylinder is buried in the powder material, both the first crushing rod and the second crushing rod are buried in the powder material. The first crushing rod rotates rapidly to stir the powder material, facilitating the airflow to drive the powder material to rise and be suctioned. At the same time, the second crushing rod cooperates with the first crushing rod. When there are particulate matters in the powder material, the first crushing rod pushes the particulate matters between the first crushing rod and the second crushing rod and uses the shearing force to crush the particulate matters, thereby preventing large particulate matters from not being suctioned and preventing particulate matters from blocking the pipeline and hindering material suction, ensuring the best working efficiency of absorption. When the telescopic cylinder descends as the powder material is continuously suctioned, through the limitation of the limit frame and the limit clamping ring, the driving rotating cylinder is moved downward, thereby synchronously moving the first crushing rod and the second crushing rod downward to ensure the stirring and crushing efficiency of the first crushing rod and the second crushing rod.

Specific embodiments

[0031] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present invention as follows.

[0032] Please refer to Figures 1-5 As shown: A material suction mechanism of a vacuum feeding machine includes a support plate 1. One side of the middle of the support plate 1 is provided with a drive motor 2. The drive shaft of the drive motor 2 penetrates through the support plate 1, and the drive motor 2 is vertically downward. One side of the end of the drive shaft of the drive motor 2 is fixedly connected with a transmission rod 3. The lower side of one end of the transmission rod 3 is rotatably connected with a material suction cylinder 4. The lower part of the material suction cylinder 4 is movably sleeved with a telescopic cylinder 5. One side of the upper part of the material suction cylinder 4 is connected with a limiting cylinder 8 for conveying powder to the vacuum feeding machine. The other side of the middle of the support plate 1 is rotatably connected with a limiting rod 9. The lower end of the limiting rod 9 is fixedly connected with a limiting ring 10. The limiting cylinder 8 movably penetrates through the limiting ring 10. Both ends of the support plate 1 are movably sleeved with telescopic plates 11, and the support plate 1 is installed with a support frame 12 through the telescopic plates 11.

[0033] In this embodiment, when vacuum feeding of powder materials is required, the whole device is installed on the upper middle part of the powder material box through the support frame 12. The telescopic plate 11 is telescoped to adapt to different widths of the powder material boxes. Subsequently, the height of the telescopic cylinder 5 is adjusted up and down so that the lower end of the telescopic cylinder 5 is buried in the powder materials, while keeping the upper part of the telescopic cylinder 5 exposed outside the powder materials. Subsequently, the nozzle of the suction pipe of the vacuum feeder is docked with the limit cylinder 8, and the vacuum feeder is started. Through the suction of the vacuum feeder and the feeding through the telescopic cylinder 5, the suction cylinder 4 and the limit cylinder 8, the powder materials are sucked and fed. At the same time, the driving motor 2 is started, the transmission rod 3 is rotated by the driving motor 2, the transmission rod 3 pushes the suction cylinder 4 to rotate around the driving motor 2, and at the same time, the limit ring 10 limits the limit cylinder 8, and then limits the suction cylinder 4 to prevent the limit cylinder 8 from rotating along with the rapid rotation of the suction cylinder 4 and avoid safety accidents. At the same time, the suction cylinder 4 pushes the telescopic cylinder 5 to rotate, and the lower part of the telescopic cylinder 5 continuously stirs the powder materials, so as to facilitate suction and keep the powder materials being continuously sucked. As the powder materials are continuously sucked, the telescopic cylinder 5 continuously moves downward, keeping the lower half of the telescopic cylinder 5 buried in the powder materials, so as to maintain the absorption efficiency of the powder materials and prevent the interruption of powder material transportation, and thus quickly and fully suck the powder materials in the box into the vacuum feeder for feeding.

[0034] Electric push rods 6 are installed on both sides of the suction cylinder 4. The upper end of the telescopic cylinder 5 is fixedly connected with a transmission plate 7, and the suction cylinder 4 movably penetrates through the middle of the transmission plate 7. The two electric push rods 6 are vertically downward, and the telescopic ends of the two electric push rods 6 are fixedly connected to the transmission plate 7. When in use, the two electric push rods 6 are telescoped synchronously to push the transmission plate 7, and the transmission plate 7 pushes the telescopic cylinder 5, so that the lower half of the telescopic cylinder 5 is kept buried in the powder materials to ensure the working efficiency when sucking the powder materials.

[0035] At the inner top of the material suction cylinder 4, a crushing motor 18 is installed. The crushing motor 18 is vertically downward, and the lower end of the drive shaft of the crushing motor 18 is fixedly connected to a transmission rotating rod 19. A transmission rotating cylinder 20 is movably sleeved at the lower end of the transmission rotating rod 19. The outer periphery of the lower end of the transmission rotating cylinder 20 is fixedly connected to a first crushing rod 23. A second crushing rod 24 is fixedly connected to the inner peripheral side wall of the lower end of the telescopic cylinder 5. During operation, the crushing motor 18 rotates the transmission rotating rod 19, the transmission rotating rod 19 drives the transmission rotating cylinder 20 to rotate, the transmission rotating cylinder 20 drives the first crushing rod 23 to rotate, and at the same time, the transmission rotating cylinder 20 moves synchronously with the movement of the telescopic cylinder 5. When the lower end of the telescopic cylinder 5 is buried in the powder material, both the first crushing rod 23 and the second crushing rod 24 are buried in the powder material. The first crushing rod 23 rotates rapidly to stir the powder material, facilitating the airflow to drive the powder material to rise and be suctioned. At the same time, the second crushing rod 24 cooperates with the first crushing rod 23. When there are particulate matters in the powder material, the first crushing rod 23 pushes the particulate matters between the first crushing rod 23 and the second crushing rod 24 and uses the shearing force to crush the particulate matters, thereby preventing large particulate matters from not being suctioned and preventing particulate matters from blocking the pipeline and hindering material suction, ensuring the best working efficiency of absorption.

[0036] Inside the material suction cylinder 4 and between the crushing motor 18 and the limiting cylinder 8, there is a shielding plate 31 for protecting the crushing motor 18. The shielding plate 31 prevents the powder material from contaminating the crushing motor 18.

[0037] A sealing ring 26 is embedded in the inner side of the top end of the telescopic cylinder 5. The sealing ring 26 is movably sleeved on the outer periphery of the material suction cylinder 4, and the sealing ring 26 remains in contact and sealed with the material suction cylinder 4. Through the sealing ring 26, the telescopic cylinder 5 maintains sealing when moving up and down on the outer periphery of the material suction cylinder 4, preventing air leakage and ensuring stable working efficiency.

[0038] A limiting clamping ring 22 is fixedly sleeved on the lower part of the transmission rotating cylinder 20. The outer periphery of the middle part of the limiting clamping ring 22 is rotatably connected to a limiting frame 21. The limiting frame 21 is fixedly connected to the inner wall of the lower end of the telescopic cylinder 5 through two connecting rods. During use, when the telescopic cylinder 5 descends as the powder material is continuously suctioned, through the limitation of the limiting frame 21 and the limiting clamping ring 22, the transmission rotating cylinder 20 moves downward, thereby synchronously moving the first crushing rod 23 and the second crushing rod 24 downward, ensuring the stirring and crushing efficiency of the first crushing rod 23 and the second crushing rod 24.

[0039] A support ring 28 is fixedly sleeved on the outer periphery of the lower end of the material suction cylinder 4. The outer peripheral side surface of the support ring 28 abuts against the inner peripheral side surface of the telescopic cylinder 5. A plurality of first inlay strips 27 are fixedly connected to the inner peripheral side surface of the telescopic cylinder 5 and are evenly distributed at equal angles. A through groove corresponding to and penetrating through the first inlay strip 27 is formed in the outer periphery of the support ring 28. During operation, the support ring 28 further maintains the sealed sleeving of the material suction cylinder 4 and the telescopic cylinder 5 to prevent air leakage. Through the limitation of the support ring 28 by the first inlay strip 27, the telescopic cylinder 5 is prevented from rotating along with the rotation of the transmission rotating cylinder 20 due to the rapid rotation of the crushing motor 18, further ensuring the steady improvement of the working efficiency.

[0040] A plurality of second inlay strips 29 are fixedly connected to the outer periphery of the transmission rotating rod 19 and are evenly distributed at equal angles. A plurality of inlay grooves are formed in the inner peripheral side surface of the transmission rotating cylinder 20 and are evenly distributed at equal angles. The inlay grooves correspond to the second inlay strips 29 one by one and are slidably connected. The transmission rotating rod 19 drives the transmission rotating cylinder 20 to rotate synchronously through the second inlay strips 29, and at the same time, it is convenient for the transmission rotating cylinder 20 to move up and down along the transmission rotating rod 19.

[0041] A plurality of first crushing rods 23 are provided. The plurality of first crushing rods 23 are evenly distributed in a double helix shape. A plurality of second crushing rods 24 are provided, and the second crushing rods 24 correspond to the first crushing rods 23 one by one. When the corresponding first crushing rod 23 and the second crushing rod 24 converge, the first crushing rod 23 and the second crushing rod 24 frictionally abut against each other. Through the first crushing rods 23 and the second crushing rods 24 evenly distributed in a double helix shape, the crushing and stirring efficiency of the first crushing rods 23 and the second crushing rods 24 is improved, facilitating the lower end of the telescopic cylinder 5 to be buried in the powder material for convenient material suction.

[0042] A plurality of support cone blocks 30 are fixedly connected to the outer surface of the lower end of the telescopic cylinder 5 and are evenly distributed at equal angles. Through the piercing ability of the support cone blocks 30, the downward movement of the telescopic cylinder 5 is facilitated. At the same time, when the lower end of the telescopic cylinder 5 abuts against the bottom of the box body and the powder material is about to be completely absorbed, the support cone blocks 30 ensure that a gap is maintained between the bottom of the telescopic cylinder 5 and the box body to ensure the continuous absorption of the powder material.

[0043] Positioning bolts 25 are threadedly inserted through one ends of the telescopic plates 11 close to the driving motor 2. The positions of the telescopic plates 11 on the support plate 1 are positioned by the positioning bolts 25, so as to maintain stable support. Support seats 13 are rotatably connected to the lower ends of the support frames 12. A lower end of each support seat 13 is fixedly connected to an L-shaped frame 14. A limiting bolt 15 is threadedly inserted through one side of the L-shaped frame 14. Two support clamping columns 17 are fixedly connected to a side of the L-shaped frame 14 away from the limiting bolt 15. The limiting bolt 15 penetrates through the L-shaped frame 14, and a support clamping plate 16 is rotatably connected to an end of the limiting bolt 15. The upper end of the support clamping plate 16 is slidably connected to the L-shaped frame 14. During operation, the support clamping plate 16 and the support clamping columns 17 clamp the inner and outer sides of the upper end of the side wall of the box body. The support clamping plate 16 is pushed by the limiting bolt 15, so that the support clamping plate 16 and the support clamping columns 17 maintain stable clamping. Due to the rotatable connection between the support seat 13 and the support frame 12, it is applicable to boxes of different shapes, thus expanding the scope of application.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
