Technical Field

[0001] The present invention belongs to the technical field of elevators, and in particular relates to a precise blanking bidirectional flipping and lifting device and method. Background Art

[0002] In the pharmaceutical manufacturing process, elevators are specialized equipment used to vertically transport raw materials, intermediates, or finished products. They are widely used in the production of solid dosage forms (such as granules, powders, and tablets). Their core function is to efficiently and safely transfer materials between different steps (such as mixing, granulation, tableting, and packaging), ensuring the continuity and containment of the production process and complying with GMP (Good Manufacturing Practice) requirements.

[0003] Although the existing lifting device can transfer raw materials when in use, the raw materials are tilted up and down during the transfer process, which easily causes powder to be raised, affecting the on-site environmental quality and the accuracy of the transfer. Therefore, a precise material unloading and bidirectional flip lifting device is proposed. Summary of the Invention

The rubber rod is vertically arranged and used in conjunction with the fixing rod.

[0011] As a further solution of the invention, the top of the control valve is rotatably connected to a swivel, and the top of the swivel is fixedly connected to a spiral cleaning piece. The filter bag is located inside the cleaning piece and contacts the cleaning piece. One side of the swivel is fixedly connected to a mounting rod, and the circumference of the second drive shaft is fixedly connected to the drive rod, which contacts the mounting rod, and a tension spring is fixedly connected between the mounting rod and one side outer wall of the box.

[0012] As a further solution of the invention, the lifting mechanism includes a reduction motor and two docking blocks. The reduction motor is fixed to the bottom inner wall of the box body.

[0016] As a further solution of the invention, a plurality of rollers are fixedly connected to the bottom of the box body, and a handle is fixedly connected to an outer wall of one side of the box body.

[0017] The present invention also provides a method for using a precise blanking bidirectional flipping and lifting device, comprising the following steps:

[0018] S1: Start the reduction motor, which drives the threaded rod to rotate, thereby lowering the fixed frame and the hopper, and then adding materials into the hopper through the feeding port. After the feeding is completed, similarly, start the reduction motor, thereby driving the back plate and the hopper to move upward;

[0019] S2: During movement, one of the piston rods of the double-headed cylinder is activated according to the direction in which the raw materials are dumped, thereby driving one of the first clamping blocks to move closer to one of the second clamping blocks, thereby clamping and fixing the rotating rod, and at the same time the fixing frame moves on the support rod;

[0020] S3: As the fixed frame continues to rise, the force-bearing rod enters the docking port on the docking block. As the fixed frame rises, the force-bearing rod is restricted by the docking port, causing the fixed frame and the hopper to flip over, thereby putting the raw materials into the guide barrel;

[0021] S4: During the process of turning over and feeding, the fan is started to extract the air in the guide barrel and discharge it into the filter bag, thus avoiding the dust in the raw materials and improving the environmental quality on site;

[0022] S5: After the turning and feeding is completed, the raw materials enter the guide barrel. When the raw materials in the guide barrel need to be discharged, the first cylinder is started, the first cylinder drives the sliding frame to move upward, the sliding frame drives the sliding rod to move upward, and then the sliding rod drives the first drive shaft and the second drive shaft to rotate, thereby discharging the materials;

[0023] S6: When the sliding frame moves, it drives the rubber rod to move. The rubber rod contacts the fixed rod and reciprocates to reset its shape, and then knocks the fixed rod, causing the guide barrel to vibrate, preventing the raw materials from adhering to the guide barrel;

[0024] S7: When the second drive shaft rotates, it also drives the drive rod to rotate. The drive rod pushes the mounting rod and the swivel to rotate, thereby rotating the cleaning sheet. The cleaning sheet squeezes different positions of the filter bag, thereby completing the cleaning of the filter bag and facilitating the powder to fall into the guide barrel.

[0025] The embodiments of the present invention have the following beneficial effects:

[0026] In the present invention, by installing a fan and a filter bag on the top of the material guide barrel, the powder can be collected by the filter bag during discharge and then discharged into the material guide barrel, thereby improving the on-site environmental quality, reducing the waste of raw materials, and improving the accuracy of material discharge.

[0027] In the present invention, the rubber rod and the fixed rod are used in conjunction with each other, so that when the sliding frame moves, the rubber rod and the fixed rod are in contact and reciprocated to reset their deformation, thereby knocking the fixed rod to vibrate the material guide barrel and prevent the raw materials from adhering to the material guide barrel.

[0028] In the present invention, a spiral cleaning sheet is installed on the circumference of the filter bag, so that the cleaning sheet squeezes different positions of the filter bag when it rotates, thereby completing the cleaning of the filter bag, facilitating the powder to fall into the material guide barrel, and maintaining the filtration efficiency of the filter bag.

[0029] In the present invention, the powder is collected by the filter bag and then discharged into the material guide barrel, thereby improving the on-site environmental quality, reducing the waste of raw materials, improving the accuracy of material feeding, and at the same time making the material guide barrel vibrate to prevent the raw materials from adhering to the material guide barrel.

[0030] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

During the feeding process, the fan 4 is started to extract the air in the material guide barrel 3 and discharge it into the filter bag 21, thereby avoiding the raising of dust in the raw materials and improving the environmental quality on site. At the same time, the extracted powder can be put into the material guide barrel 3 again to improve the accuracy of the feeding. The bottom of the material guide barrel 3 is hinged with a discharge plate 22 for controlling the feeding.

[0043] Two control mechanisms, both of which are arranged on one side of the box body 1 and are used to control the discharge of the two material guide barrels 3;

[0044] The material lifting mechanism is arranged in the box body 1 for lifting raw materials.

[0045] Example 2

[0046] Improvements based on Example 1: Refer to the attached Figures 1-6 .

[0047] The first and second drive shafts 33 are fixed to the discharge plate 22 and the control shaft of the control valve 20 on one side, and the slide rods 37 are respectively connected to the first and second drive shafts 23 and 33 on one side. The first and second drive shafts 33 are respectively fixed to the discharge plate 22 and the control shaft of the control valve 20 on one side, and the first and second drive shafts 23 and 33 on one side are fixed to the connection plate 35 on one side. A through slide 36 is provided on one side of the connection plate 35, and the slide rods 37 are respectively connected to the slide rails 36 for sliding connection. The first cylinder 26 is fixed to the outer wall of one side of the box body 1, and one end of the piston rod of the first cylinder 26 is fixed to the slide rail 25. When the first cylinder 26 is started, the first cylinder 26 drives the slide rail 25 to move upward, and the slide rail 25 drives the slide rod 37 to move upward, and then the slide rod 37 is used to drive the first and second drive shafts 23 and 33 to rotate, thereby performing discharge.

[0048] In particular, a plurality of evenly distributed fixed rods 28 are fixedly connected to the circumference of the material guide barrel 3, and a rubber rod 27 is fixedly connected to one side of the sliding frame 25. The rubber rod 27 and the fixed rod 28 are vertically arranged and used in conjunction with each other. When the sliding frame 25 moves, it drives the rubber rod 27 to move. The rubber rod 27 contacts and reciprocates with the fixed rod 28 to reset the deformation, and then knocks on the fixed rod 28, causing the material guide barrel 3 to vibrate, thereby preventing the raw materials from adhering to the material guide barrel 3.

[0049] The top of the control valve 20 is rotatably connected to a swivel 29, and a spiral cleaning piece 30 is fixedly connected to the top of the swivel 29. The filter bag 21 is located inside the cleaning piece 30 and conflicts with the cleaning piece 30. One side of the swivel 29 is fixedly connected to a mounting rod 31. The circumference of the second drive shaft 33 is fixedly connected to a driving rod 34. The driving rod 34 contacts the mounting rod 31. When the second drive shaft 33 rotates, it also drives the driving rod 34 to rotate. The driving rod 34 pushes the mounting rod 31 and the swivel 29 to rotate, thereby causing the cleaning piece 30 to rotate. The cleaning piece 30 squeezes different positions of the filter bag 21, thereby completing the cleaning of the filter bag 21 and facilitating the powder to fall into the material guide barrel 3. A tension spring 32 is fixedly connected between the mounting rod 31 and the outer wall of one side of the box body 1. The tension spring 32 is used to drive the cleaning piece 30 to reset.

[0050] In the present invention, the lifting mechanism includes a reduction motor 10 and two docking blocks 7. The reduction motor 10 is fixed to the bottom inner wall of the box body 1. One end of the output shaft of the reduction motor 10 is fixedly connected to a threaded rod 5. The circumferential thread of the threaded rod 5 is connected to a back plate 9. One side of the back plate 9 is fixedly connected to two support rods 13. A fixing frame 11 is placed on the top of the two support rods 13. The surface of the fixing frame 11 is fixedly connected to a hopper 12. The reduction motor 10 drives the threaded rod 5 to rotate, thereby causing the fixing frame 11 and the hopper 12 to move. The bottom of the hopper 12 is fixedly connected to two force rods 18. The two docking blocks 7 are both fixed to the inner wall of one side of the box body 1. The bottoms of the two docking blocks 7 are each provided with an inclined docking interface 8. The two docking interfaces 8 are respectively used in conjunction with the two force rods 18. The force rods 18 enter the docking interface 8 on the docking block 7. When the fixed frame 11 rises, the force rods 18 are restricted by the docking interface 8, thereby causing the fixed frame 11 and the hopper 12 to flip over.

[0051] In particular, the bottom of the fixing frame 11 is rotatably connected to two support rods 13, and one side of the back plate 9 is fixedly connected to two second clamping blocks 17. The two support rods 13 are respectively on one side of the two second clamping blocks 17. One side of the back plate 9 is fixedly connected to a double-headed cylinder 14, and one end of the piston rods at both ends of the double-headed cylinder 14 is fixedly connected to a first clamping block 15. The bottom of the fixing frame 11 is fixedly connected to two symmetrically arranged rotating rods 16. The two first clamping blocks 15 are respectively used in conjunction with the two second clamping blocks 17 to clamp the rotating rod 16. Starting one of the piston rods of the double-headed cylinder 14 drives one of the first clamping blocks 15 to approach one of the second clamping blocks 17, thereby clamping and fixing the rotating rod 16, which facilitates the rotation of the fixing frame 11.

[0052] It should be noted that a guide rod 6 is fixedly connected between the top inner wall and the bottom inner wall of the box body 1 , and the guide rod 6 slides through the back plate 9 , and the guide rod 6 plays a role in guiding the back plate 9 .

[0053] In the present invention, a feeding port is provided on one side of the box body 1, and the feeding port is convenient for feeding.

[0054] In particular, a plurality of rollers are fixedly connected to the bottom of the box body 1, and there are four rollers, two of which are directional and the other two are universal wheels, which are convenient to use. A handle is fixedly connected to the outer wall of one side of the box body 1.

[0055] The present invention also provides a method for using a precise blanking bidirectional flipping and lifting device, comprising the following steps:

[0056] S1: Start the reduction motor 10, which drives the threaded rod 5 to rotate, thereby lowering the fixed frame 11 and the hopper 12, and then feeding the material into the hopper 12 through the feeding port. After the feeding is completed, similarly, start the reduction motor 10, thereby driving the back plate 9 and the hopper 12 to move upward;

[0057] S2: During movement, one of the piston rods of the double-headed cylinder 14 is activated according to the direction in which the raw materials are dumped, thereby driving one of the first clamping blocks 15 to move closer to one of the second clamping blocks 17, thereby clamping and fixing the rotating rod 16, and at the same time, the fixing frame 11 moves on the support rod 13;

[0058] S3: As the fixing frame 11 continues to rise, the force-bearing rod 18 enters the docking port 8 on the docking block 7. As the fixing frame 11 rises, the force-bearing rod 18 is restricted by the docking port 8, causing the fixing frame 11 and the hopper 12 to flip over, thereby feeding the raw materials into the guide barrel 3.

[0059] S4: During the process of turning over and feeding, the fan 4 is started to extract the air in the guide barrel 3 and discharge it into the filter bag 21, thereby avoiding the raising of dust in the raw materials and improving the environmental quality on site;

[0060] S5: After the turning and feeding is completed, the raw materials enter the guide barrel 3. When the raw materials in the guide barrel 3 need to be discharged, the first cylinder 26 is started, and the first cylinder 26 drives the sliding frame 25 to move upward, and the sliding frame 25 drives the sliding rod 37 to move upward, and then the sliding rod 37 drives the first drive shaft 23 and the second drive shaft 33 to rotate, thereby discharging the raw materials;

[0061] S6: When the sliding frame 25 moves, it drives the rubber rod 27 to move. The rubber rod 27 contacts the fixed rod 28 and reciprocates to reset, thereby knocking the fixed rod 28, causing the guide barrel 3 to vibrate, thereby preventing the raw materials from adhering to the guide barrel 3;

[0062] S7: When the second drive shaft 33 rotates, it also drives the drive rod 34 to rotate. The drive rod 34 pushes the mounting rod 31 and the swivel 29 to rotate, thereby rotating the cleaning sheet 30. The cleaning sheet 30 squeezes different positions of the filter bag 21, thereby completing the cleaning of the filter bag 21 and facilitating the powder to fall into the material guide barrel 3.

After the addition is completed, similarly, start the reduction motor (10), thereby driving the back plate (9) and the hopper (12) to move upward; S2: During movement, one of the piston rods of the double-headed cylinder (14) is activated according to the direction in which the raw materials are dumped, thereby driving one of the first clamping blocks (15) to approach one of the second clamping blocks (17), thereby clamping and fixing the rotating rod (16), and at the same time, the fixing frame (11) moves on the support rod (13); S3: When the fixed frame (11) continues to rise, the force-bearing rod (18) enters the docking port (8) on the docking block (7). As the fixed frame (11) rises, the force-bearing rod (18) is restricted by the docking port (8), causing the fixed frame (11) and the hopper (12) to flip over, thereby feeding the raw materials into the guide barrel (3); S4: During the process of turning over and feeding, the fan (4) is started, and the fan (4) extracts the air in the guide barrel (3) and discharges it into the filter bag (21), thereby avoiding the raising of dust in the raw materials and improving the environmental quality on site; S5: After the turning and feeding is completed, the raw materials enter the guide barrel (3). When the raw materials in the guide barrel (3) need to be discharged, the first cylinder (26) is started, the first cylinder (26) drives the sliding frame (25) to move upward, the sliding frame (25) drives the sliding rod (37) to move upward, and then the sliding rod (37) drives the first drive shaft (23) and the second drive shaft (33) to rotate, thereby discharging the raw materials; S6: When the sliding frame (25) moves, the rubber rod (27) is driven to move. The rubber rod (27) contacts the fixed rod (28) and reciprocates to reset the deformation, thereby knocking the fixed rod (28) to vibrate the guide barrel (3) to prevent the raw materials from adhering to the guide barrel (3); S7: When the second drive shaft (33) rotates, it also drives the drive rod (34) to rotate. The drive rod (34) pushes the mounting rod (31) and the rotating ring (29) to rotate, thereby rotating the cleaning sheet (30). The cleaning sheet (30) squeezes different positions of the filter bag (21), thereby completing the cleaning of the filter bag (21) and facilitating the powder to fall into the guide barrel (3).
