[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 6 As shown, this embodiment provides a drying device for the production of plastic packaging containers, including a drying chamber 1, a hollow cavity inside the drying chamber 1, a warm air blower 2 on the side of the drying chamber 1, and a flip-open top cover 3 at the top of the drying chamber 1. A rotatable pressure ring 31 is provided in the center of the top cover 3, and the pressure ring 31 rotates synchronously when the top cover 3 is flipped.

[0031] Furthermore, the hollow cavity is equipped with a replaceable drying module and a rotatable drive shaft 4. The drying module includes a rotatable rotating drum 5, which is sleeved on the outside of the drive shaft 4. Inside the rotating drum 5, there is a liftable pressure drum 6, and an axially arranged drying rack 7 is rotatably arranged on the outside of the rotating drum 5.

[0032] Specifically, the lower end of the drying chamber 1 is provided with a fixedly connected drive motor 41. The rotating shaft of the drive motor 41 is fixedly connected to the drive shaft 4 through a coupling. The drive motor 41 drives the drive shaft 4 to rotate synchronously.

[0033] Furthermore, a drive disk 42 is fixedly connected to the drive shaft 4. When the drive shaft 4 rotates, it drives the drive disk 42 to rotate synchronously. The drive disk 42 is provided with an axially arranged drive groove 43.

[0034] Specifically, the top of the rotating drum 5 is provided with a handle 51, the bottom of the rotating drum 5 is provided with an axially arranged locking block 52, the inside of the rotating drum 5 is provided with a through hole 53, the outside of the rotating drum 5 is provided with an axially arranged mounting block 54, and the mounting block 54 is provided with a fixedly connected baffle 55 and a rotatable drying rack 7.

[0035] Furthermore, the rotating barrel 5 is mounted on the drive shaft 4, which passes through the through hole 53. The locking block 52 is locked in the drive groove 43 for limiting and fixing. When the drive shaft 4 rotates, it drives the drive disc 42, the locking block 52, and the rotating barrel 5 to rotate synchronously.

[0036] Specifically, the bottom of the pressure barrel 6 is provided with a rotatable push wheel 61. The number and installation position of the push wheel 61 are the same as those of the mounting block 54. A spring 62 is provided below the pressure barrel 6. The upper end of the spring 62 is fixedly connected to the bottom end of the pressure barrel 6, and the lower end of the spring 62 is fixedly connected to the bottom end of the inside of the rotating barrel 5. When the pressure barrel 6 is pressed, the push wheel 61 descends and the spring 62 contracts. After the external force is released, the spring 62 pushes the pressure barrel 6 and the push wheel 61 to rise and return to their original positions.

[0037] Furthermore, the drying rack 7 is inserted into the mounting block 54 and rotatably connected to it. The drying rack 7 has an array of arc-shaped frames 72 on one side and a bent edge 71 at the lower end. The bent edge 71 is inserted into the mounting block 54. The push wheel 61 is tangent to the mounting block 54. When there is no external force pressing the pressure barrel 6, the drying rack 7 unfolds to the outside of the rotating barrel 5. The drying rack 7 stops unfolding after being blocked by the baffle 55.

[0038] On the other side of the drying rack 7, there are multiple sets of placement racks 73. The placement racks 73 are arranged in order of height and the radius gradually increases. The placement racks 73 are provided with axially arranged placement seats 74. The size of the placement seats 74 can be selected according to the diameter and height of different plastic packaging cups. A through air pipe 741 is provided at the center of the placement seat 74. A drainage groove 742 is provided on the side of the placement seat 74.

[0039] The working principle of this utility model:

[0040] When in use, select a drying rack 7 of different sizes according to the diameter and height of different plastic packaging cups, and place the plastic packaging cups upside down on the placement seat 74. At this time, the pressure tank 6 is in the raised state, the drying rack 7 is tilted, and the residual liquid inside the plastic packaging cups on the placement seat 74 is discharged along the drain groove 742.

[0041] Next, the entire drying module is lifted by the handle 51 and installed into the hollow cavity. The drive shaft 4 passes through the through hole 53, and the locking block 52 is locked in the drive groove 43 for limiting and fixing.

[0042] When the top cover 3 is closed, the pressure ring 31 presses down on the pressure barrel 6 and descends. When the pressure barrel 6 descends, it drives the push wheel 61 to descend synchronously. The spring 62 contracts. The push wheel 61 presses down on the bent edge 71 and drives the drying rack 7 to reverse and stand up. When the top cover 3 is completely closed, the drying rack 7 and the rotating barrel 5 remain horizontal. The arc frame 72 contacts and presses the side wall of the rotating barrel 5.

[0043] The drive motor 41 drives the drive shaft 4 to rotate. When the drive shaft 4 rotates, it drives the drive disc 42, the clamping block 52, the rotating drum 5, the pressure drum 6, the pressure ring 31, and the drying rack 7 to rotate synchronously. Then the warm air blower 2 starts to dry the food. Hot air can enter the plastic packaging cup through the air pipe 741 to dry it.

[0044] After drying is complete, open the top cover 3 and remove the dried plastic packaging cup. If the drying module needs to be replaced, simply pull it out and replace it.
