Description

Technical Field

[0001] This invention relates to the field of pharmaceutical equipment technology, and in particular to a platform lifting mechanism that facilitates material loading. Background Technology

[0002] In the pharmaceutical industry, there is a need for lifting forklift platforms for raising and lowering hoppers.

[0003] In traditional material lifting processes, the hopper is typically pushed to a designated position manually before being lifted by mechanical equipment. However, this method has many inconveniences, such as high labor intensity and low efficiency when manually pushing the hopper, and the hopper being prone to swaying during lifting, affecting stability and safety. In addition, existing lifting mechanisms often lack effective auxiliary feeding and hopper stabilization devices, resulting in the need for additional manpower and resources in actual operation to ensure hopper stability and smooth lifting. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as high labor intensity and low efficiency when manually pushing the hopper, easy shaking of the hopper during the lifting process, and lack of effective auxiliary feeding and hopper stabilization devices in the lifting mechanism. Therefore, this invention proposes a platform lifting mechanism that facilitates feeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A platform lifting mechanism for easy loading includes a base and a top seat, the base and the top seat are arranged in parallel, the top seat is located directly above the base, and mounting slots are provided on the sides of the base and the top seat that are close to each other. Two first sliding blocks and two second sliding blocks are symmetrically arranged and slidably connected inside the two mounting slots respectively. A set of lifting components for lifting the top seat is provided between the second sliding blocks and the first sliding blocks.

[0007] Two symmetrically arranged fixing plates are fixedly connected to one side of the top seat, and the same set of auxiliary feeding components for assisting feeding is arranged between the two fixing plates;

[0008] A fixed back plate is fixedly connected to one side of the top of the top seat, and a stabilizing component for stabilizing the hopper is provided on one side of the fixed back plate.

[0009] In one possible design, the lifting assembly includes eight symmetrically arranged mounting seats that are respectively fixedly connected to the bottom of the first sliding block and the top of the second sliding block. The eight mounting seats are arranged symmetrically in pairs. Two rotating rods are rotatably connected between four mounting seats on the same side. The two rotating rods are arranged crosswise, and the same bolt passes through the two rotating rods. Two nuts are symmetrically arranged on the outer wall of the bolt.

[0010] In one possible design, the feeding assembly includes a rotating shaft rotatably connected to one side of a fixed plate, a common feeding plate being fixedly connected between two rotating shafts, a plurality of first rotating rods rotatably passing through one side of the feeding plate, and a flat groove being provided at one end of the feeding plate.

[0011] In one possible design, a rectangular groove is provided on one side of the feeding plate, and a rectangular slot is provided on one side of the top seat. The same push plate is slidably connected between the inner walls of the two sides of the rectangular slot. Two first tension springs are fixedly connected between one side of the push plate and one side of the inner wall of the rectangular slot. The push plate is used in conjunction with the rectangular groove.

[0012] In one possible design, the stabilizing component includes two grooves formed on one side of the fixed back plate, with a slider slidably connected inside the grooves. A second tension spring is fixedly connected between one side of the slider and the inner wall of one side of the groove. A sliding side plate is fixedly connected to one side of the slider. Two symmetrically arranged second strip-shaped holes are formed on the top of the top seat. A second rectangular block is fixedly connected to one side of the bottom of the sliding side plate, and the bottom of the second rectangular block extends into the interior of the second strip-shaped holes.

[0013] In one possible design, a servo motor is fixedly connected to one side of the top seat. The output shaft of the servo motor rotates through the top seat and is fixedly connected to a bidirectional lead screw. The bidirectional lead screw is threaded through two first sliding blocks. An L-shaped block is fixedly connected to one side of each first sliding block. The L-shaped block is located inside a second strip hole and cooperates with a second rectangular block.

[0014] In one possible design, a triangular block is fixedly connected to one side of the first sliding block, two symmetrically arranged first rectangular blocks are fixedly connected to the bottom of the push plate, and two symmetrically arranged first strip holes are opened on the top of the top seat. The first rectangular block passes through the first strip hole and cooperates with the triangular block.

[0015] In one possible design, the top of the top seat is rotatably connected to two symmetrically arranged second rotating rods. A rotating side plate is fixedly sleeved on the outer wall of the second rotating rod, and a second gear is fixedly sleeved on the outer wall of the second rotating rod. A clearance hole is opened at the bottom of one side of the rotating side plate, and the clearance hole is used in conjunction with the second gear. A first gear is rotatably connected to the top of the top seat, and the first gear meshes with the second gear. A rack is fixedly connected to one side of the sliding side plate, and the rack meshes with the first gear.

[0016] In one possible design, two symmetrically arranged support blocks are fixedly connected to one side of the top seat, and a sloping groove is opened on one side of the support block, which is used in conjunction with the feeding plate.

[0017] In one possible design, sliding inner rods are fixedly connected to the bottom four corners of the top seat, and U-shaped sleeves are fixedly connected to the top four corners of the base, with the sliding inner rods slidably connected inside the U-shaped sleeves.

[0018] In this application, during use, the hopper is pushed to the top of the top seat by the feeding plate. At this time, since the bottom of the feeding plate is provided with a flat groove, and the support block supports the feeding plate, and the inclined groove is adapted to the feeding plate, the stability of the feeding plate can be guaranteed. In addition, due to the setting of multiple first rotating rods, the friction of the hopper can be reduced, and the feeding difficulty can be reduced.

[0019] After the material is fed, the servo motor can be started. The output shaft of the servo motor drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the two first sliding blocks to move closer to each other. The first sliding blocks drive the rotating rod to rotate. At this time, the rotating rod drives the two second sliding blocks below to move closer to each other, thereby lifting the top seat upward and realizing the lifting process of the material.

[0020] At the same time, when the first sliding block moves, it will drive the triangular block to move laterally. The two triangular blocks will move closer to each other, and the triangular block will push the first rectangular block, which will then move inside the first strip hole. The first rectangular block will drive the push plate to move laterally, and the push plate will stretch the first tension spring. At this time, the push plate will enter the interior of the rectangular groove, and the push plate will lift the feeding plate. The feeding plate will start to rotate around the rotating shaft and be adjusted to a horizontal state.

[0021] Furthermore, the first sliding block will cause the L-shaped blocks on both sides to move closer to each other. The two L-shaped blocks move inside the second strip hole. At this time, the L-shaped blocks no longer abut against the second rectangular block, thus releasing the braking state of the sliding side plate. The two sliders move closer to each other under the tension of the second tension spring. The sliders drive the sliding side plate to move laterally. The two sliding side plates clamp the hopper to ensure the stability of the device.

[0022] When the two sliding side plates approach each other, they will drive the first gear to rotate through the rack, the first gear to rotate the second gear, the second gear to rotate the second rotating rod, and the second rotating rod to rotate the rotating side plate. At this time, the rotating side plate can rotate to one side of the hopper, so that the hopper can be protected from the front again.

[0023] When the device moves down, the servo motor can make the two first sliding blocks move away again. As the device moves down, the first sliding blocks push the second rectangular block through the L-shaped block. At this time, the sliding side plates on both sides move away again, and the sliding side plates can make the two rotating side plates open again. At the same time, the first rectangular block is no longer blocked by the triangular block, and then the push plate is reset under the tension of the first tension spring. The feeding plate is reset under the action of gravity, which is convenient for the next use.

[0024] Beneficial effects: Simplifies the feeding process and reduces labor intensity: By setting up auxiliary feeding components and utilizing the design of the feeding plate and the first rotating rod, the friction between the hopper and the platform is effectively reduced, making the feeding process easier and faster, and reducing the labor intensity of workers.

[0025] Improved lifting efficiency: A servo motor drives a bidirectional lead screw, which in turn moves the first and second sliding blocks, enabling rapid lifting and lowering of the top seat and improving lifting efficiency.

[0026] Ensuring hopper stability: By incorporating a stabilizing component, the hopper is effectively clamped using the cooperation of sliding and rotating side plates, preventing it from swaying during lifting and ensuring its stability. Simultaneously, the design of the L-shaped block and the second rectangular block enables braking and releasing of the sliding side plate, further enhancing stability.

[0027] High degree of automation and easy operation: This mechanism achieves automated operation of lifting and stabilizing the hopper through the drive of a servo motor, which simplifies the operation process and reduces the skill requirements for workers.

[0028] Compact structure and highly adaptable: This mechanism is reasonably designed, compact in structure, occupies little space, and can adapt to hoppers of different sizes and weights, thus having high adaptability and practicality. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1; Refer to Figure 1-7A platform lifting mechanism for easy loading, used in the pharmaceutical equipment field, includes: a base 1 and a top seat 3, which are arranged in parallel. The top seat 3 is located directly above the base 1. Mounting slots 15 are provided on the sides of the base 1 and the top seat 3 that are close to each other. Two symmetrically arranged first sliding blocks 11 and two symmetrically arranged second sliding blocks 19 are slidably connected inside the two mounting slots 15. A lifting assembly for lifting the top seat 3 is provided between the second sliding blocks 19 and the first sliding blocks 11. The lifting assembly includes eight symmetrically arranged mounting seats 17, which are fixedly connected to the bottom of the first sliding blocks 11 and the top of the second sliding blocks 19. The eight mounting seats 17 are symmetrically arranged in pairs. Two rotating rods 18 are rotatably connected between four mounting seats 17 on the same side. The two rotating rods 18 are arranged crosswise. A single bolt 22 is rotatably inserted through the top seat 3. Two nuts 23 are symmetrically arranged on the outer wall of the bolt 22. A servo motor 2 is fixedly connected to one side of the top seat 3. The output shaft of the servo motor 2 rotatably passes through the top seat 3 and is fixedly connected to a bidirectional lead screw 20. The bidirectional lead screw 20 is threaded through two first sliding blocks 11. An L-shaped block 21 is fixedly connected to one side of the first sliding block 11. The L-shaped block 21 is located inside the second strip hole 41 and works in conjunction with the second rectangular block 34. After the material is loaded, the servo motor 2 can be started. The output shaft of the servo motor 2 drives the bidirectional lead screw 20 to rotate. The bidirectional lead screw 20 drives the two first sliding blocks 11 to move closer to each other. The first sliding blocks 11 drive the rotating rod 18 to rotate. At this time, the rotating rod 18 drives the two second sliding blocks 19 below to move closer to each other, thereby lifting the top seat 3 upward and realizing the lifting process of the material.

[0039] Two symmetrically arranged fixed plates 31 are fixedly connected to one side of the top seat 3. A set of auxiliary feeding components for assisting feeding is provided between the two fixed plates 31. The feeding component includes a rotating shaft 30 rotatably connected to one side of the fixed plate 31. A single feeding plate 7 is fixedly connected between the two rotating shafts 30. Multiple first rotating rods 8 rotatably pass through one side of the feeding plate 7. A flat groove 9 is opened at one end of the feeding plate 7 to push the hopper to the top of the top seat 3. Since the flat groove 9 is provided at the bottom of the feeding plate 7, and the support block 27 supports the feeding plate 7, and the inclined groove 28 is adapted to the feeding plate 7, the stability of the feeding plate 7 can be ensured. Furthermore, the multiple first rotating rods 8 reduce the friction of the hopper and reduce the difficulty of feeding. A rectangular groove 29 is opened on one side of the feeding plate 7, and a rectangular groove 14 is opened on one side of the top seat 3. A single pusher plate 26 is slidably connected between the inner walls of the two sides of the rectangular groove 14. Two symmetrically arranged first tension springs 25 are fixedly connected between the side and the inner wall of one side of the rectangular groove 14. At the same time, when the first sliding block 11 moves, it will drive the triangular block 16 to move laterally. The two triangular blocks 16 approach each other and push the first rectangular block 24, thereby causing the first rectangular block 24 to move inside the first strip hole 13. The first rectangular block 24 drives the push plate 26 to move laterally. The push plate 26 stretches the first tension spring 25. At this time, the push plate 26 enters the interior of the rectangular groove 29. The push plate 26 lifts the feeding plate 7, and the feeding plate 7 starts to rotate around the rotating shaft 30 and is adjusted to a horizontal state. The push plate 26 works in conjunction with the rectangular groove 29. A triangular block 16 is fixedly connected to one side of the first sliding block 11. Two symmetrically arranged first rectangular blocks 24 are fixedly connected to the bottom of the push plate 26. Two symmetrically arranged first strip holes 13 are opened on the top of the top seat 3. The first rectangular block 24 passes through the first strip hole 13 and works in conjunction with the triangular block 16.

[0040] A fixed back plate 4 is fixedly connected to one side of the top of the top seat 3. A stabilizing component for stabilizing the hopper is provided on one side of the fixed back plate 4. The stabilizing component includes two sliding grooves 35 opened on one side of the fixed back plate 4. A slider 33 is slidably connected inside the sliding grooves 35. A second tension spring 32 is fixedly connected between one side of the slider 33 and one side inner wall of the sliding groove 35. A sliding side plate 5 is fixedly connected to one side of the slider 33. Two symmetrically arranged second strip holes 41 are opened on the top of the top seat 3. The first sliding block 11 will drive the L-shaped blocks 21 on both sides to move closer to each other. The two L-shaped blocks 21 are inside the second strip holes 41. The L-shaped block 21 no longer abuts against the second rectangular block 34, thus releasing the braking state of the sliding side plate 5. The two sliders 33 approach each other under the tension of the second tension spring 32, causing the sliders 33 to move the sliding side plate 5 laterally. The two sliding side plates 5 clamp the hopper, ensuring the stability of the device. A second rectangular block 34 is fixedly connected to one side of the bottom of the sliding side plate 5. The bottom of the second rectangular block 34 extends into the interior of the second strip hole 41. Two symmetrically arranged second rotating rods 40 are rotatably connected to the top of the top seat 3. Rotating side plates 6 are fixedly sleeved on the outer walls of the second rotating rods 40. A second gear 38 is fixedly fitted onto the outer wall of the rotating side plate 6. A clearance hole 39 is provided at the bottom of one side of the rotating side plate 6, which cooperates with the second gear 38. A first gear 37 is rotatably connected to the top of the top seat 3, and the first gear 37 meshes with the second gear 38. A rack 36 is fixedly connected to one side of the sliding side plate 5, and the rack 36 meshes with the first gear 37. When the two sliding side plates 5 approach each other, the rack 36 drives the first gear 37 to rotate, the first gear 37 drives the second gear 38 to rotate, the second gear 38 drives the second rotating rod 40 to rotate, and the second rotating rod 40 drives the rotating side plate 6 to rotate. At this point, the rotating side plate 6 can be rotated to one side of the hopper, providing further protection for the hopper from the front. When the device moves down, the servo motor 2 can cause the two first sliding blocks 11 to move away again. As the device moves down, the first sliding blocks 11 push the second rectangular block 34 through the L-shaped block 21. At this point, the sliding side plates 5 on both sides move away again, and the sliding side plates 5 can cause the two rotating side plates 6 to open again. Meanwhile, the first rectangular block 24 is no longer blocked by the triangular block 16, and the push plate 26 is reset under the tension of the first tension spring 25. The feeding plate 7 is reset under the action of gravity, making it convenient for the next use.

[0041] Example 2; Reference Figure 1-6 An improvement based on embodiment 1: Two symmetrically arranged support blocks 27 are fixedly connected to one side of the top seat 3. An inclined groove 28 is opened on one side of the support block 27. The inclined groove 28 is used in conjunction with the feeding plate 7. Sliding inner rods 12 are fixedly connected to the four bottom corners of the top seat 3. U-shaped sleeve plates 10 are fixedly connected to the four top corners of the base 1.
