Technical Field

[0002] PET food barrels are mostly produced by processes such as blow molding, injection molding, thermoforming, and rotational molding, and burrs will inevitably be generated during the production process. These burrs affect the quality and appearance of PET food barrels and need to be removed. In the related art, the dry ice deburring method is used to remove the burrs on PET food barrels. This method uses dry ice particles to accelerate and impact on the product to remove the burrs in a high-pressure air flow. The dry ice instantaneously vaporizes during this process and does not produce any secondary waste. What needs to be cleaned up is only the dirt removed. However, since the movement trajectory of the burrs is uncontrollable during the use of this solution, the burrs can adhere to any part of the food barrel, resulting in the need for subsequent re-cleaning of the food barrel, which affects the processing efficiency of the food barrel; and the burrs on the food barrel appear randomly, and in the prior art, the burrs are usually removed by spraying all-round on the parts of the food barrel where burrs are likely to be generated, increasing the consumption of dry ice.

[0029] The electrical components involved in this application are all prior arts. Those skilled in the art understand their connection methods. Through those skilled in the art, all the electrical components in this application are connected to their adapted power supplies through wires, and a suitable controller is selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, refer to the following description. The electrical components are electrically connected in the order of their working sequence one after another. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.
[0030] In summary, when the burr repair device for PET food buckets is in use, the conveying structure 3 is used to transport the PET food buckets to be repaired. If the burrs of the bucket mouth of the PET food bucket need to be repaired, the position of the PET food bucket on the conveying structure 3 is as shown in the attached Figure 1 to the attached Figure 4 As shown, during the transportation of the PET food bucket, the burr detector 4 can detect the burrs at the bucket mouth. The control system in the device can judge the position and quantity of the burrs at the bucket mouth according to the detection results of the burr detector 4. When the PET food bucket moves below the through hole, the conveying structure 3 stops working, and the electric telescopic rod 10 drives the lower sealing plate 12 to move downward until the lower sealing plate 12 sleeves on the PET food bucket, and the bucket mouth of the PET food bucket is located above the horizontal end of the lower sealing plate 12, as shown in the attached Figure 3 and the attached Figure 4 As shown; the electric telescopic rod 13 drives the upper sealing plate 19 to move downward until the upper sealing plate 19 seals the inner cavity of the PET food bucket to prevent the debris generated during the repair process from falling into the PET food bucket.
[0031] The dry ice deburring machine 5 and the servo motor 11 both work. The servo motor 11 drives the connected gear 17 to rotate. The gear 17 drives the rotating ring 15 to rotate through the engaged toothed ring. The rotating ring 15 drives the nozzle 14 to rotate. The work of the dry ice deburring machine 5 makes the nozzle 14 spray dry ice particles. The dry ice particles sprayed by the nozzle 14 can clean the burrs at the bucket mouth of the PET food bucket. And the control system in the device controls the work of the dry ice deburring machine 5 according to the detection results of the burr detector 4, so that the dry ice particles sprayed by the nozzle 14 are sprayed onto the burrs to reduce the dry ice loss.
[0032] After the burr cleaning of the PET food bucket is completed, the dust removal structure works. The work of the ion blower 7 makes the air spraying plate 6 evenly spray the gas containing a large number of positive and negative ions. The gas sprayed by the air spraying plate 6 can blow the burrs generated during the repair process into the guiding box 8. The burrs slide down along the guiding box 8 into the collecting box 9, which is convenient for the unified treatment of the burrs. After the dust removal is completed, both the lower sealing structure and the upper sealing structure are reset, and the conveying structure can continue to transport the PET food buckets.
