Technical Field

[0001] The utility model relates to the technical field of plastic particle inspection equipment, in particular to a plastic particle appearance inspection equipment. Background Art

[0002] Thermoplastic plastic particles are a kind of raw materials with thermoplastic resin as the main component and various additives added. After the thermoplastic plastic particles are produced, they need to be inspected by inspectors. The appearance inspection of thermoplastic plastic particles mainly includes the following steps: 1. Observe the shape, color and surface finish of the particles. Qualified plastic particles should have a uniform color, no bubbles and impurities, and the shape should meet the specification requirements. At the same time, check whether there are scratches, breakages, flaws, particles, oil stains, discoloration, cracks and other defects on the surface of the particles; 2. Check whether the particles have bubbles. Bubbles are one of the common appearance defects of thermoplastic plastic particles. It is necessary to carefully observe whether there are obvious bubbles on the surface of the particles; 3. Check the impurities of the particles. Impurities are also an important factor affecting the quality of plastic particles. It is necessary to check whether there are obvious impurities in the particles.

[0003] When conducting appearance inspection, it is necessary to ensure that the inspection environment is well-lit. Currently, a white enamel tray is required for inspection, and then a separate dedicated lighting source is used to illuminate the plastic particles. Even if a suitable lighting source is provided, the light shines on the plastic particles from top to bottom and then reflects to the eyes. When observing tailing particles, it is not easy to find the tailing part of the particles, and it is difficult to observe the bubbles in the plastic particles, which requires the observer to carefully identify. If the inspection is carried out under such conditions for a long time, the inspector will need to spend more time on the inspection, which will cause damage to the inspector's eyes, and it is easy to miss the inspection of tailing particles and unqualified particles containing bubbles.

The upper frame plate 11 is provided with a plurality of locking members 5 for quickly locking the lower frame plate 12. The locking members 5 enable the upper frame plate 11 and the lower frame plate 12 to be quickly and conveniently disassembled and assembled, so that maintenance personnel can disassemble it to repair or replace the internal LED light strip 4.

[0035] The LED light strip 4 is clamped between the upper frame plate 11 and the lower frame plate 12. The LED light strip 4 is located on the inner side of the frame plate 1 and is provided with a circle around the inner side of the frame plate 1. The LED light strip 4 is provided on the side to prevent the light from being directly reflected on the eyes of the examiner. The equipment is provided with an adjustment switch connected to the LED light strip 4. The brightness of the LED light strip 4 can be adjusted by the adjustment switch to protect the eyes of the examiner.

[0036] The locking component 5 includes a locking block 51 and a moving block 54. The moving block 54 is provided with a limiting rod 57. The limiting rod 57 is sleeved with a spring 56 and a limiting plate 58. The spring 56 is located between the limiting plate 58 and the moving block 54. One end of the locking block 51 is connected to the moving block 54. The spring 56 is used to pull the locking block 51 so that the locking end 511 on the locking block 51 can pull the lower frame plate 12 and the upper frame plate 11 to lock them tightly together.

[0037] A locking end 511 is provided at one end of the locking block 51 away from the moving block 54, and a connecting end 121 connected to the locking member 5 is provided on the lower frame plate 12. A connecting groove 122 matching with the locking end 511 is provided on the connecting end 121.

[0041] When in use, the plastic particles to be inspected are placed on the irradiation plate 2, and the LED light strip 4 is powered on to illuminate the irradiation plate 2. The light passes through the irradiation plate 2 to irradiate and inspect the plastic particles, so that the LED light can directly illuminate the plastic particles from bottom to top, making it easier for the inspector to observe the bubbles in the plastic particles, and there is no need for a separate lighting source or to select lighting conditions with higher requirements. The brightness of the LED light strip 4 can be adjusted by adjusting the brightness through a switch, so that the inspector can choose a suitable brightness to inspect the plastic particles, which can protect the inspector's eyes to a large extent and avoid direct damage to the inspector's eyes. Compared with the inspection of plastic particles by a white enamel plate, the device can facilitate the observer to observe and inspect the bubbles in the plastic particles, further improving the inspector's work efficiency, and effectively reducing the time required for inspection, so that the inspector can complete the inspection in a shorter time.

[0042] When the LED in the frame plate 1 is damaged and needs to be repaired and replaced, the moving block 54 is moved toward the lower frame plate 12, and the moving block 54 pushes the locking block 51 to move together. When the locking block 51 moves downward, it first moves downward along the guide hole 512 for a distance. As the locking block 51 continues to move, the locking block 51 hinged to the moving block 54 can rotate outward through the guide hole 512, so that the locking end 511 on the locking block 51 moves out of the connecting groove 122. At this time, the positioning rod 55 corresponds to the positioning hole on the positioning plate 111, and the positioning rod 55 can be pushed toward the positioning hole, so as to move the positioning rod 55 into the positioning hole, and locate the position of the moving block 54 to avoid automatic reset after releasing the moving block 54;

[0043] After all the locking parts 5 are operated in the above manner, the upper frame plate 11 and the lower frame plate 12 can be directly separated. After the upper frame plate 11 and the lower frame plate 12 are separated, the internal LED light strip 4 can be exposed, and the staff can directly repair or replace the LED light strip 4. The upper frame plate 11 and the lower frame plate 12 can be quickly and conveniently disassembled and assembled, which makes it easier for maintenance personnel to disassemble it for maintenance when necessary.

[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed or modified in any way.
