Description

Technical Field

[0001] This utility model relates to the field of plastic testing equipment, and in particular to a testing device for testing the properties of plastics. Background Technology

[0002] Plastic pellets are raw materials for storing, transporting, and processing plastics in a semi-finished form. During the manufacturing process, waste plastics need to be crushed, cleaned, and dried, and then transported to an extruder for melting and extrusion. The extruded strips of plastic are then transported to a pelletizing machine to be cut into pellets.

[0003] Since most plastic particles tend to clump together during the plastic granulation process, a camera is used to inspect the appearance quality of the particles in the area when testing their performance. However, due to the disordered arrangement of the particles, a lot of time needs to be spent manually separating the plastic particles to avoid affecting the accuracy of the test, which is quite troublesome.

[0004] Therefore, it is necessary to provide a new testing device for plastic performance testing to solve the above-mentioned technical problems. Utility Model Content

[0017] In the specific implementation process, such as Figures 1-5 As shown, the testing device for plastic performance testing includes a frame 1, a plastic pellet feeding assembly, a dispensing assembly, and a testing assembly. The dispensing assembly and the testing assembly are located at opposite ends of the frame 1, and the output end of the plastic pellet feeding assembly is located above the dispensing assembly. The dispensing assembly includes a dispensing tray 2, a conveying mechanism, a feeding box 3, and four elastic telescopic mechanisms fixed to the four corners of the feeding box 3. The dispensing tray 2 is located on the conveying mechanism. Multiple placement slots 4 for placing plastic granules are arrayed on the dispensing tray 2. The granules fall into the placement slots 4 through the discharge port 14 of the cylinder 10, forming a single-layer orderly arrangement. The feeding box 3 is located above the dispensing tray 2. Multiple feeding cylinders 5 corresponding to the positions of the placement slots 4 are arranged side by side at the bottom of the feeding box 3. The four elastic telescopic mechanisms are fixedly installed on the top of the frame 1. The inner wall of one side of the feeding box 3 is inclined downward to the top of the feeding cylinder 5. Multiple feeding cylinders 5 are arranged side by side at the bottom of the feeding box 3. The downward inclination angle of the inner wall of the feeding box 3 guides the granules to fall accurately into the feeding cylinders 5. The four elastic telescopic mechanisms adjust the height of the feeding box 3 in real time. It is worth noting that the number of material distribution trays 2 can be increased according to demand, and they can be arranged in a stacked manner.

[0018] In some embodiments, the elastic telescopic mechanism includes a connecting plate 15, a base 16, a movable rod 17, and a sleeve 18.

The other end of the sleeve 18 is fixedly connected to one end of the connecting plate 15. The reset spring 19 causes the feeding box 3 to automatically reset under the action of gravity, ensuring that the particles are accurately aligned with the feeding cylinder 5. The elastic telescopic mechanism eliminates the risk of particle jamming and can also prevent multiple particles from falling from the feeding cylinder 5 at the same time, realizing single-particle arrangement, which is convenient for subsequent plastic performance testing.

[0019] In some embodiments, the detection assembly includes a detection frame 6 and two opposing telescopic electric cylinders 7. The two telescopic electric cylinders 7 are respectively fixedly installed on the top of the frame 1. The two ends of the detection frame 6 are respectively fixedly connected to the output ends of the two telescopic electric cylinders 7. The bottom wall of the detection frame 6 is also provided with a detection camera 8. The two telescopic electric cylinders 7 work synchronously to drive the detection frame 6 to move up and down, so that the detection camera 8 is accurately aligned with the plastic particles on the dispensing tray 2.

[0020] In some embodiments, reference is made to Figure 4 As shown, the plastic granule feeding assembly includes a support 9, a cylinder 10, an auger rod 11, a drive motor 12, and a storage box 13 for storing plastic granules. The support 9 is located on one side of the frame 1. The cylinder 10 is fixedly and inclined on the support 9. One end of the cylinder 10 is provided with a discharge port 14, which is directly above the feeding box 3. The end of the cylinder 10 away from the discharge port 14 is connected to the inner cavity of the storage box 13. The auger rod 11 is rotatably installed inside the cylinder 10. The drive motor 12 is fixedly installed at one end of the cylinder 10, and the output end of the drive motor 12 is fixedly connected to one end of the auger rod 11. The plastic granules in the storage box 13 enter the cylinder 10 through the cylinder 10. The drive motor 12 drives the auger rod 11 to rotate, conveying the granules from the storage box 13 to the discharge port 14 of the cylinder 10. The pitch of the auger rod 11 and the tilt angle of the cylinder 10 are designed in coordination to ensure a stable granule flow rate and avoid accumulation or blockage.

[0021] In some embodiments, reference is made to Figure 5As shown, the transmission mechanism includes a power motor 20, a transmission belt 21, and two opposing transmission rollers 22. The two transmission rollers 22 are rotatably mounted on one side of the frame 1. The two ends of the transmission belt 21 are respectively sleeved on the outer surface of the two transmission rollers 22. The power motor 20 is fixedly mounted on one side of the frame 1. The output end of the power motor 20 is fixedly connected to one of the transmission rollers 22. The power motor 20 drives the transmission roller 22 to rotate, which in turn drives the transmission belt 21 to move, sending the material distribution plate 2 directly below the material box 3.

[0022] The working principle of this utility model is as follows: When the device is in use, the drive motor 12 drives the auger rod 11 to rotate, conveying the particles from the storage box 13 to the discharge port 14 of the cylinder 10. The downward tilt angle of the inner wall of the feeding box 3 guides the particles to fall accurately into the feeding cylinder 5. The four elastic telescopic mechanisms adjust the height of the feeding box 3 in real time. The power motor 20 drives the transmission roller 22 to rotate, which drives the transmission belt 21 to move and send the distribution plate 2 to the bottom of the feeding box 3. The two telescopic electric cylinders 7 work synchronously, driving the detection frame 6 to move up and down, so that the detection camera 8 is accurately aligned with the plastic particles on the distribution plate 2. The detection camera 8 captures images of the particle surface and analyzes the particle shape, size and surface defects in real time.
