[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1-6 ,in, Figure 1 A schematic diagram of a preferred embodiment of the PET plastic preform production apparatus provided by this utility model; Figure 2 This is a schematic diagram of the installation structure of the first servo motor in this utility model;Figure 3 This is a schematic diagram of the internal structure of the cleaning tub in this utility model; Figure 4 This is a schematic diagram of the card slot structure in this utility model; Figure 5 This is a schematic diagram of the opening of the first bottle mouth hole in this utility model; Figure 6 This is a schematic diagram of the second bottle opening in this utility model. The PET plastic preform production device includes: a washing tank 1 and a support column 5. A drain pipe is fixedly installed on one side of the washing tank 1, and a water valve is provided on the drain pipe to facilitate the discharge of wastewater. A through groove 6 is opened on the support column 5, and a first lifting screw 7 is rotatably installed in the through groove 6. A second servo motor is fixedly installed on the top of the support column 5, and its output shaft is fixedly connected to the top of the first lifting screw 7. A lifting arm 8 is threadedly installed on the first lifting screw 7. Both sides of the lifting arm 8 extend outside the support column 5 and are slidably connected to the support column 5, which ensures that the lifting arm 8 can only perform linear lifting. A rectangular frame is fixedly installed on one side of the lifting arm 8. A rectangular frame 9 has a rotating shaft 10 rotatably mounted on the side of the frame away from the support column 5. A third servo motor is fixedly mounted inside the rectangular frame 9, with its output shaft fixedly connected to one end of the rotating shaft 10. An eccentric plate 11 is fixedly mounted at the end of the rotating shaft 10. A slot 12 is formed at the top of the eccentric plate 11, and an assembly arm 13 is fixedly mounted in the slot 12 by bolts. A shelf 14 is fixedly mounted on the side of the assembly arm 13 away from the rectangular frame 9. The shelf 14 is not concentric with the rotating shaft 10, so when the rotating shaft 10 rotates, the shelf 14 can rotate along a larger diameter circle, thus smoothly mounting the assembled arm. The preforms are brought into the cleaning tank 1 for cleaning. Multiple placement holes 15 are provided on the top of the shelf 14. Multiple water passage holes 16 are provided on the inner bottom wall of each placement hole 15. Multiple protrusions 17 are fixedly installed on the inner bottom wall of each placement hole 15. The ends of these protrusions 17 are spherical. When the preforms are placed into the placement holes 15, they are supported by the spherical ends of the protrusions 17, thus engaging with the water passage holes 16 to allow the cleaning fluid to effectively clean the bottom of the preforms, improving the thoroughness of the cleaning. An extension arm 18 is fixedly installed on the side of the shelf 14 away from the rectangular frame 9. A second liter is rotatably mounted on this extension arm 18. The lowering screw 19 has a linkage block 20 threaded onto it. A pressure strip 21 is fixedly installed on one side of the linkage block 20. The pressure strip 21 has multiple first bottle mouth holes 22, which are adapted to multiple placement countersunk holes 15. A rubber strip 23 is fixedly installed at the bottom of the pressure strip 21. The rubber strip 23 has multiple second bottle mouth holes 24, which are adapted to multiple first bottle mouth holes 22. By cooperating with the first bottle mouth holes 22 and the second bottle mouth holes 24, the preform can be fixed in the placement countersunk hole 15. At the same time, the rubber strip 23 can prevent damage to the plastic preform.

[0024] In the above method, in order to improve the cleaning effect, a bearing shaft 2 is rotatably installed on the bottom inner wall of the cleaning tank 1, and multiple stirring blades 3 arranged in a ring array are fixedly installed on the bearing shaft 2. A first servo motor is fixedly installed at the bottom of the cleaning tank 1, and its output shaft is fixedly connected to the bottom end of the bearing shaft 2. By rotating the stirring blades 3, the cleaning liquid can be driven to flow rapidly, thereby improving the cleaning effect on the preform.

[0025] In this method, in order to collect the tilted impurity particles, a mesh frame 4 is provided inside the cleaning tank 1. Connecting ears are fixedly installed on both outer walls of the cleaning tank 1 with bolts, and the bottom of the two connecting ears is fixedly connected to the mesh frame 4.

[0026] In this method, in order to align the mounting holes on the assembly arm 13 with the mounting holes on the eccentric plate 11 at one time to improve the ease of installation, two spacers are fixedly sleeved on the assembly arm 13, and the eccentric plate 11 is located between the two spacers.

[0027] The working principle of the PET plastic preform production device provided by this utility model is as follows:

[0028] Before cleaning, pour enough cleaning solution into cleaning bucket 1;

[0029] When it is necessary to clean the preforms, first place multiple preforms in the corresponding placement holes 15 and support them on the protrusions 17. Then rotate the second lifting screw 19, and the linkage block 20 will descend. Multiple first bottle opening holes 22 and second bottle opening holes 24 will pass through the bottle openings of the corresponding preforms until the bottom edge of the second bottle opening hole 24 contacts the preform.

[0030] At this point, the preforms are positioned, and then the third servo motor is started. Its output shaft drives the rotating shaft 10 to rotate, and the eccentric plate 11 rotates with the shelf 14. After the eccentric plate 11 rotates 180°, the third servo motor is turned off. At this point, the preforms change from the original bottle mouth facing up to the bottle mouth facing down. Then, the second servo motor is started in the forward direction. Its output shaft drives the first lifting screw 7 to rotate, and the lifting arm 8 will drive the rectangular frame 9 to descend. Finally, multiple preforms descend together until the preforms are completely submerged in the cleaning solution, and then the second servo motor is turned off.

[0031] Then, the first servo motor is started, and its output shaft drives the bearing shaft 2 to rotate, which in turn drives multiple stirring blades 3 to rotate. During the rotation, the cleaning liquid can flow, thus cleaning the outer and inner sides of the preform at the same time.

[0032] After cleaning, the first servo motor is turned off, and the second servo motor is started in reverse. The preforms gradually rise. After rising above the cleaning tank 1, the third servo motor is started again. After the eccentric plate 11 rotates 180° again, the third servo motor is turned off. Then the second lifting screw 19 is rotated to make the pressure bar 21 rise. When it is completely separated from the cleaned preforms, the preforms can be removed and the next batch of preforms to be cleaned can be placed. This process is repeated until all preforms are cleaned.

[0033] In subsequent use, the wastewater can be discharged by opening the water valve. At the same time, the mesh frame 4 can separate the washed impurity particles. The mesh frame 4 can be directly removed from the washing tank 1 for centralized cleaning of the impurity particles.

[0034] Compared with related technologies, the PET plastic preform production apparatus provided by this utility model has the following advantages:

[0035] This utility model provides a production device for PET plastic preforms. By opening multiple placement holes 15 on the shelf 14, multiple preforms to be cleaned can be fixed at one time. Then, by rotating the eccentric plate 11, the bottle mouth of the preform is turned downwards and then inserted into the cleaning liquid for cleaning. This can increase the number of preforms cleaned in a single cleaning process and reduce the physical labor of workers, thereby improving cleaning efficiency and the degree of automation.
