Description

Technical Field

[0001] This utility model relates to a lifting and opening hydraulic baler. Background Technology

[0002] After powdered materials are bagged, the bag structure is relatively loose, making them prone to instability and collapse during stacking. Therefore, a baling machine is needed to compress them into a more regular shape before stacking. Traditional hydraulic balers compress from both top and bottom, creating arc-shaped bulges on the sides under pressure. When stacking powder bags, the length and width of the stack are large due to these bulges, resulting in a large space occupation and a small contact area between adjacent bags, making the stack prone to collapse. Therefore, a device that can compress powder bags from multiple sides is needed. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a lifting and opening hydraulic baler that can compress powder bags from multiple sides, making the powder bags neat and orderly.

[0004] To achieve this objective, the structure adopted in this utility model is as follows: a lifting and opening hydraulic baler, including a frame, the frame including four vertically arranged columns connected to the four corners of the base, the top of the four columns being provided with a connecting frame to form a cuboid frame; movable frames are symmetrically arranged on the front and rear sides of the cuboid frame, and fixed frames are symmetrically arranged on the left and right sides, the fixed frames being fixedly connected to the columns; lifting cylinders are symmetrically arranged on both sides of the movable frames and connected to the columns; a crossbeam is provided above each fixed frame, the two crossbeams are connected to each other by two longitudinal beams, and a cylinder seat is provided between the two longitudinal beams; a pressure plate assembly is provided in the center of the frame, the pressure plate assembly including a fixed pressure plate, a movable pressure plate and an upper pressure plate, the fixed frame is connected to the fixed pressure plate by a push cylinder, the movable frame is connected to the movable pressure plate by a push cylinder, and the cylinder seat is connected to the upper pressure plate by a push cylinder; a hydraulic station is provided next to the frame, the lifting cylinder and the push cylinder are connected to the hydraulic station through pipelines.

[0005] Guide rails are respectively installed on the two uprights of the movable frame. The guide rails include clamps and stainless steel grooves. The stainless steel grooves clamp the two sides of the movable frame. The clamps are symmetrically arranged on both sides of the stainless steel grooves and are connected to the uprights by bolts.

[0006] A nylon slider is installed between the movable frame and the stainless steel tank.

[0007] Both the fixed frame and the movable frame are grid-like frames. A cylinder hole is set in the center of the grid-like frame, and the pushing cylinder is set in the cylinder hole. Guide sleeves are evenly arranged around the cylinder hole, and guide posts are inserted in the guide sleeves. The guide posts are connected to the fixed pressure plate or the movable pressure plate. Multiple guide sleeves are arranged around the cylinder seat on the longitudinal beam. Guide posts are inserted in the guide sleeves and connected to the upper pressure plate.

[0008] The guide sleeve has a through hole in the middle and annular grooves at both ends. Connecting holes are evenly arranged on the outside of the grooves. A copper sleeve is placed in each groove. Each copper sleeve is pressed against both ends of the guide sleeve by a flange ring. The flange ring has a through hole in the center and connecting holes are evenly arranged around the through hole. Bolts connect the flange ring and the guide sleeve through the connecting holes on the guide sleeve and the flange ring. The center of the flange ring protrudes towards the guide sleeve, and the protruding part contacts the copper sleeve. The copper sleeve is a graphite copper sleeve. The guide post is inserted in the center of the guide sleeve and the flange ring.

[0009] The guide post is provided with a first dust cover and a second dust cover at both ends.

The two lower connecting rods are parallel to each other and are connected to the top ends of the two columns respectively. The two upper connecting rods are parallel to each other and are connected to the two ends of the two lower connecting rods respectively.

[0011] A vertical signal detection frame is installed on the longitudinal beam, and multiple signal detectors are installed on the vertical signal detection frame; multiple signal detection frames are installed on the column connected to the lifting cylinder, and each signal detection frame is equipped with a signal detector.

[0012] Its beneficial effects are: The structure of this utility model is reasonable and ingenious. The conveyor belt for conveying powder bags passes through the frame. When the powder bag reaches the bottom of the pressure plate group, the pressure plate group applies pressure from the front, back, left, right and top of the powder bag to make it more regular. Then the movable pressure plate and movable frame rise, and the conveyor belt sends out the packaged powder bag. The more regular powder bag saves more space when stacking and has better stability.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1-6 The lifting and opening hydraulic baler shown includes a frame, such as Figure 2As shown, the frame includes four vertically arranged columns 1, which are connected to the four corners of the base 4. A connecting frame is provided at the top of the four columns 1 to form a cuboid frame. The connecting frame includes two lower connecting rods 3 and two upper connecting rods 2. The two lower connecting rods 3 are parallel to each other and connect to the top of the two columns 1 respectively. The two upper connecting rods 2 are parallel to each other and connect to the two ends of the two lower connecting rods 3 respectively. This connecting frame has a large welding area and a relatively strong structure. The open top facilitates the installation and operation of the equipment below. Movable frames 5 are symmetrically arranged on the front and rear sides of the cuboid frame, and fixed frames 6 are symmetrically arranged on the left and right sides. The fixed frames 6 are fixedly connected to the columns 1. Lifting cylinders 8 are symmetrically arranged on both sides of the movable frames 5 and connected to the columns 1. A crossbeam 9 is provided above each fixed frame 6. The crossbeam 9 is an I-beam structure, and its two ends are connected to the columns 1 by bolts or welding. Two crossbeams 9 are connected to each other by two longitudinal beams 10, and a cylinder seat is provided between the two longitudinal beams 10. A pressure plate assembly is installed in the center of the frame, such as Figure 3 As shown, the pressure plate assembly includes a fixed pressure plate 21, a movable pressure plate 22, and an upper pressure plate 16. The fixed frame 6 is connected to the fixed pressure plate 21 via a push cylinder 17. The movable frame 5 is connected to the movable pressure plate 22 via a push cylinder 17. The cylinder seat is connected to the upper pressure plate 16 via a push cylinder 17. A hydraulic station 15 is set next to the frame. The lifting cylinder 8 and the push cylinder 17 are connected to the hydraulic station via pipelines.

[0024] A certain space is left between the bottom of the fixed frame 6 and the top of the base 4, with a height of approximately 30-100cm, allowing the conveyor belt of the powder bags to pass directly through the frame. The conveying and packaging of the powder bags are carried out on the conveyor belt, making it more efficient and faster. The lifting cylinder 8 realizes the lifting operation of the movable frame 5. When the powder bags are conveyed, the movable frame 5 drives the movable pressure plate 22 to rise, allowing the powder bags to enter the center of the frame. Then, the movable frame 5 drives the movable pressure plate 22 to fall. Then, the fixed pressure plate 21, the movable pressure plate 22, and the upper pressure plate 16 squeeze and shape the powder bags from the front, back, left, right, and top. The movable frame 5 rises again to send the powder bags out, making the powder bags form a more regular shape, which is conducive to more stable stacking of the powder bags.

[0025] like Figure 4 As shown, guide rails 7 are respectively installed on the two side columns 1 of the movable frame 5. Each guide rail 7 includes a clamping plate 71 and a stainless steel channel 72. The stainless steel channel 72 clamps both sides of the movable frame 5. The clamping plates 71 are symmetrically arranged on both sides of the stainless steel channel 72 and are connected to the columns 1 by bolts. This structure makes the installation of the guide rails 7 more convenient. The stainless steel channel 72 is wear-resistant and rust-resistant, ensuring the smooth movement of the guide rails 7. A nylon slider 23 is installed between the movable frame 5 and the stainless steel channel 72. The nylon slider 23 has self-lubricating properties, which can compensate for jamming caused by vertical width errors of the guide rails 7, further ensuring the smooth movement of the movable frame 5 on the guide rails 7.

[0026] Both the fixed frame 6 and the movable frame 5 are grid-like frames. A cylinder hole 13 is located in the center of the grid-like frame, and a pushing cylinder 17 is positioned within the cylinder hole 13. Guide sleeves 14 are evenly arranged around the cylinder hole 13, with guide posts 18 inserted through them. The guide posts 18 are connected to the fixed pressure plate 21 or the movable pressure plate 22. Multiple guide sleeves 14 are arranged around the cylinder seat on the longitudinal beam 10, with guide posts 18 inserted through them and connected to the upper pressure plate 16. A grid-like reinforcing frame is provided on the outer side of the fixed pressure plate 21, the movable pressure plate 22, and the upper pressure plate 16. A pressure connecting ring 20 is provided on the grid-like reinforcing frame corresponding to the pushing cylinder 17, and a guide post connecting block 19 is provided on the grid-like reinforcing frame corresponding to the guide post 18. The grid-like reinforcing frame strengthens the structural strength of the fixed pressure plate 21, the movable pressure plate 22, and the upper pressure plate 16, while also evenly distributing the pressure of the pushing cylinder 17, ensuring uniform pressure on the powder bag.

[0027] like Figure 5 , Figure 6 The guide sleeve 14 has a through hole in the middle and annular grooves at both ends. Connecting holes are evenly distributed on the outer side of the grooves. A copper sleeve 28 is placed in each groove, and each copper sleeve 28 is pressed against both ends of the guide sleeve 14 by a flange ring 27. The flange ring 27 has a through hole in the center, and connecting holes are evenly distributed around the through hole. Bolts connect the flange ring 27 to the guide sleeve 14 through the connecting holes on the guide sleeve 14 and the flange ring 27. The center of the flange ring 27 protrudes towards the guide sleeve 14, and the protruding part contacts the copper sleeve 28. The copper sleeve 28 is a graphite copper sleeve. A guide post 18 is inserted between the guide sleeve 14 and the center of the flange ring 27. The graphite copper sleeve provides lubrication, and the diameter of the through hole in the center of the guide sleeve 14 can be larger than the diameter of the guide post 18, reducing the friction between the guide sleeve 14 and the guide post. The structure of the flange ring 27 facilitates the inspection and replacement of the copper sleeve 28.

[0028] The guide post 18 is provided with a first dust cover 24 and a second dust cover 26 at both ends. One end of the first dust cover 24 is connected to the end of the guide post 18 via a clamp 25, and the other end is connected to the guide sleeve 14 via a clamp 25. One end of the second dust cover 26 is connected to the guide sleeve 14 via a clamp 25, and the other end is connected to the fixed pressure plate 21, movable pressure plate 22, or upper pressure plate 16 corresponding to the guide post 18. The dust covers prevent the guide post 18 from contacting the outside environment during the extension and retraction of the guide post 18, preventing impurities from entering and causing scratches and jamming between the guide post and the copper sleeve 28, extending the service life of the guide post 18, and reducing the maintenance frequency.

[0029] A vertical signal detection frame 12 is installed on the longitudinal beam 10, and multiple signal detectors are installed on the vertical signal detection frame 12. Multiple signal detection frames 11 are installed on the column 1 connected to the lifting cylinder 8, and each signal detection frame 11 is equipped with a signal detector. The signal detectors detect the position of the corresponding guide column 18 or movable frame 5. When a signal detector detects a signal, it transmits the signal to the controller. The controller provides feedback based on the detected position signal and performs corresponding lifting operations. Long strip-shaped connecting grooves are provided on the vertical signal detection frame 12 and the signal detection frame 11, allowing the signal detectors to be adjusted to the corresponding positions as needed, thus adjusting the pressure applied to the powder bag.
