Description

Technical Field

[0001] This utility model relates to the technical field of PPO plastic pellet defect detection device, specifically to a PPO plastic pellet defect detection device. Background Technology

[0002] Plastic pellets, also known as plastic granules, are raw materials used for storing, transporting, and processing plastics in a semi-finished form. During processing into pellets, impurities may appear in the raw materials, affecting the quality of the final pellets. Therefore, it is necessary to inspect the plastic pellets during production. The current publication number CN206369737U discloses a plastic particle appearance inspection device, including a plastic particle receiving tank. The bottom of the plastic particle receiving tank is rotatably mounted on a bracket. One end of the plastic particle receiving tank is wider than the other end. The narrower end of the plastic particle receiving tank is provided with a discharge pipe, and the wider end of the plastic particle receiving tank is provided with a lifting device. When the lifting device lifts upward, the wider end of the plastic particle receiving tank rises with the bracket as the fulcrum. This utility model uses a lifting device, which is a cylinder. The cylinder pushes the wider end of the plastic particle receiving tank. When the lifting device lifts upward, the wider end of the plastic particle receiving tank rises with the bracket as the fulcrum. The inspected plastic particles slide down to the narrower end of the plastic particle receiving tank and are discharged from the discharge pipe. The operator can use a bag to cover the discharge pipe to collect the plastic particles. To address the issue of inspecting plastic particles, existing technology involves using a cylinder to push the wider end of the plastic particle receiving tank. When the lifting device lifts the tank upwards, the wider end rises with the support as the fulcrum. The inspected plastic particles slide down to the narrower end of the tank and are discharged through the discharge pipe. However, this method still requires manual handling to inspect the plastic particles, resulting in low inspection efficiency. Utility Model Content

[0006] A further improvement of this utility model is that: a vibration component is installed in the middle of the rotating shaft, a spring is installed inside the sleeve, and an upper sleeve is installed at one end of the spring, allowing the spring to move inside the upper sleeve.

[0007] A further improvement of the present invention is that a support plate is fixedly connected to one end of the upper sleeve, and a placement frame is fixedly connected to the surface of the support plate for placing plastic granules.

[0008] A further improvement of the present invention is that the vibration component includes a linkage block, the linkage block is fixedly connected to the middle of the rotating shaft, a connecting column is fixedly connected to the middle of the linkage block, a transmission column is sleeved on the surface of the connecting column, a locking column is sleeved at one end of the transmission column, and receiving blocks are fixedly connected to both ends of the locking column. The transmission column drives the receiving blocks to move up and down, and at the same time, the slot impacts the cone block.

[0009] A further improvement of this utility model is that: a slot is provided at one end of the receiving block, a limiting sleeve is fixedly connected to one end of the receiving block, a cone block is movably connected inside the slot, a connecting rod is fixedly connected to the surface of the cone block, cone blocks are fixedly connected to both ends of the connecting rod, a compression spring is sleeved on the surface of the connecting rod, one end of the compression spring is fixedly connected to one end of the limiting sleeve, the compression spring on the limiting sleeve is squeezed and rebounded, causing the cone block at the upper end of the connecting rod to reciprocate and impact within the fixed sleeve.

The motor drives the rotating shaft to rotate, which in turn drives the linkage block and connecting column to rotate. The connecting column drives the transmission column to move up and down, and the transmission column drives the receiving block to move up and down. Simultaneously, the slot impacts the cone block. During this impact, the compression spring on the limiting sleeve is squeezed and rebounds, causing the upper cone block of the connecting rod to reciprocate within the fixed sleeve, thus impacting the support plate. This causes the support plate and the placement frame to shake, resulting in the plastic granules inside the placement frame moving. As the placement frame shakes and impacts, the spring rebounds within the sleeve, assisting in the movement of the support plate and the placement frame. When it is no longer necessary to observe the plastic granules, the motor is stopped, and the entire mechanism loses its driving force. By vibrating the plastic granules inside the placement frame, the plastic granules are moved, eliminating the need for manual inspection and improving detection efficiency.

[0012] This utility model provides a defective PPO plastic pellet detection device. When the motor is started, it drives a first gear to rotate, which in turn drives a second gear to rotate. The second gear then drives a rotating column to rotate, which in turn drives a rotating disk to rotate. The motor is a servo motor, capable of intermittent rotation, allowing for adjustment of different magnifying glasses on the rotating disk. This facilitates the adjustment of different magnifying glasses for observing the plastic pellets, improving the practicality of the detection device. Attached Figure Description

A motor 22 is installed on the surface of the connecting plate 20. A first gear 23 is fixedly connected to the output end of the motor 22. A second gear 24 is meshed with one end of the first gear 23. The second gear 24 is rotatably connected to one side of the connecting plate 20. A rotating column 25 is installed at one end of the second gear 24. A rotating disk 26 is fixedly connected to one end of the rotating column 25. A magnifying glass 27 is installed on the surface of the rotating disk 26. Specifically, the motor 22 is started, which drives the first gear 23 to rotate. The first gear 23 drives the second gear 24 to rotate, the second gear 24 drives the rotating column 25 to rotate, and the rotating column 25 drives the rotating disk 26 to rotate. The motor 22 is a servo motor and can rotate intermittently. The magnification of the magnifying glass 27 varies.

[0016] Example 2 like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the placement mechanism 3 includes a mounting plate 30, which is disposed on one side of the fixing frame 1. A support block 32 is fixedly connected to the bottom of the mounting plate 30. A sleeve 31 is installed on the surface of the mounting plate 30. A slot is opened on the surface of the mounting plate 30. A motor 33 is installed on one side of the mounting plate 30. A rotating shaft 34 is installed at the output end of the motor 33. A vibration component 35 is installed in the middle of the rotating shaft 34. A spring 36 is installed inside the sleeve 31. An upper sleeve 37 is installed at one end of the spring 36. A support plate 38 is fixedly connected to one end of the upper sleeve 37. A placement frame 39 is fixedly connected to the surface of the support plate 38. The vibration component 35 includes a linkage block 350, which is fixedly connected to the middle of the rotating shaft 34. A connecting post 351 is fixedly connected to the middle of the linkage block 350. A transmission column 352 is sleeved on the surface of column 351. A locking column 353 is sleeved on one end of the transmission column 352. A receiving block 354 is fixedly connected to both ends of the locking column 353. A slot 355 is opened on one end of the receiving block 354. A limiting sleeve 358 is fixedly connected to one end of the receiving block 354. A cone block 356 is movably connected inside the slot 355. A connecting rod 357 is fixedly connected to the surface of the cone block 356. Both ends of the connecting rod 357 are fixedly connected to the cone block 356. A compression spring 359 is sleeved on the surface of the connecting rod 357. One end of the compression spring 359 is fixedly connected to one end of the limiting sleeve 358. A connecting sleeve 3593 is movably connected to the surface of the limiting sleeve 358. An installation sleeve 3591 is movably connected to the surface of the connecting sleeve 3593. A fixing sleeve 3592 is movably connected to one end of the installation sleeve 3591. The fixing sleeve 3592 is fixedly connected to the bottom of the support plate 38. Specifically, the plastic granules are placed in the placement frame 39, and then the motor 33 is started. The motor 33 drives the rotating shaft 34 to rotate, which in turn drives the linkage block 350 and the connecting column 351 to rotate. The connecting column 351 drives the transmission column 352 to move up and down, and the transmission column 352 drives the receiving block 354 to move up and down. At the same time, the slot 355 impacts the cone block 356. While the cone block 356 is impacting, it also causes the compression spring 359 on the limiting sleeve 358 to compress. The spring rebounds, causing the upper cone block 356 of the connecting rod 357 to reciprocate within the fixed sleeve 3592, thereby impacting the support plate 38 and causing the support plate 38 and the placement frame 39 to shake. This causes the plastic granules inside the placement frame 39 to shake. When the placement frame 39 is impacted and shaken, the spring 36 rebounds within the sleeve 31, assisting in the movement of the support plate 38 and the placement frame 39. When it is no longer necessary to observe the plastic granules, the motor 33 is stopped, causing the entire mechanism to lose its driving force.

[0017] The working principle of this PPO plastic pellet defect detection device will be explained in detail below.

[0018] like Figure 1-4 As shown, motor 22 is started, which drives the first gear 23 to rotate. The first gear 23 drives the second gear 24 to rotate, which in turn drives the rotating column 25 to rotate. The rotating column 25 drives the rotating disk 26 to rotate. Motor 22 is a servo motor and can rotate intermittently. Plastic pellets are placed in the placement frame 39, and then motor 33 is started. Motor 33 drives the rotating shaft 34 to rotate, which in turn drives the linkage block 350 and the connecting column 351 to rotate. The connecting column 351 drives the transmission column 352 to move up and down, and the transmission column 352 drives the receiving block 354 to move up and down. At the same time, slot 3... 55 impacts the cone block 356. Simultaneously, the cone block 356 impacts, causing the compression spring 359 on the limiting sleeve 358 to spring back, causing the upper cone block 356 of the connecting rod 357 to reciprocate within the fixed sleeve 3592, thereby impacting the support plate 38. This causes the support plate 38 and the placement frame 39 to shake, resulting in the plastic granules inside the placement frame 39 shaking. As the placement frame 39 impacts and shakes, the spring 36 springs back within the sleeve 31, assisting in the movement of the support plate 38 and the placement frame 39. When it is no longer necessary to observe the plastic granules, the motor 33 is stopped, causing the entire mechanism to lose its driving force.

[0019] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
