[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] Please refer to the following: Figures 1-7 ,in, Figure 1 A schematic diagram of a preferred embodiment of the plastic bottle dryer provided by this utility model; Figure 2 This is a schematic diagram of the rear view structure of this utility model; Figure 3 This is a schematic diagram showing the arrangement of plastic bottles during the drying process in this utility model; Figure 4 This is a schematic diagram of the ventilation hole in this utility model; Figure 5 This is a schematic diagram showing the disassembled state of the exhaust pipe and the baffle sleeve in this utility model; Figure 6 This is a schematic diagram of the connection structure between the rotating shaft and the bidirectional threaded sleeve in this utility model; Figure 7 This is a schematic diagram of the connection structure between the screw and the mounting plate in this utility model.
[0026] The plastic bottle dryer includes: a support base 1, with multiple placement slots 2 on the top of the support base 1. These placement slots 2 have a large inner diameter, allowing for the placement of plastic bottles of various diameters for drying, thus increasing its applicability. Two electric push rods 3 are fixedly installed on the top of the support base 1. A single top support plate 4 is fixedly installed on the output shaft of the two electric push rods 3. A ventilation pipe 5 is fixedly installed at the bottom of the top support plate 4. Multiple smaller diameter exhaust pipes 6 are fixedly installed at the bottom of the ventilation pipe 5. Multiple exhaust holes 7 are provided on each exhaust pipe 6. These holes 7 are distributed around the body and bottom of the exhaust pipe 6, which can blow out hot air more comprehensively and increase the uniformity of hot air drying. In addition, the multiple exhaust pipes 6 are aligned with the axis of the multiple placement slots 2, which allows the exhaust pipes 6 to be smoothly inserted into the plastic bottles. A hot air blower 8 is fixedly installed on the top of the top support plate 4 by two columns. The air outlet of the hot air blower 8 is connected to the ventilation pipe 5 through the air guide pipe 9, which passes through the top support plate 4.
[0027] In the above method, in order to clamp the plastic bottle and accurately confine it to the center position of the placement slot 2, a concave seat 10 is fixedly installed on the support base 1, and a rotating shaft 11 is rotatably installed inside the concave seat 10. One end of the rotating shaft 11 extends outside the concave seat 10 for easy rotation operation. Multiple bidirectional threaded sleeves 12 are fixedly sleeved on the rotating shaft 11. Two linkage bars 13 are threadedly installed on each of the multiple bidirectional threaded sleeves 12. A locking arc plate 14 is fixedly installed on one side of each of the multiple linkage bars 13. The two corresponding locking arc plates 14 are matched, and the center lines of the two corresponding locking arc plates 14 are aligned with the center line of the opposite direction. The center lines of the corresponding placement slots 2 are on the same vertical line. By rotating the rotating shaft 11, the threaded engagement between the bidirectional threaded sleeve 12 and the linkage bar 13 can be used to move the corresponding two linkage bars 13 away from each other or separate, thereby clamping and positioning the plastic bottle. In order to ensure that the linkage bar 13 can only move in a straight line, a single bar is fixed in the concave seat 10. The single bar passes through multiple linkage bars 13 and slides through multiple linkage bars 13. In addition, the design of the locking arc plate 14 can adapt to plastic bottles of multiple sizes and specifications, and can clamp and position various plastic bottles.
[0028] In this method, to accommodate the height of the plastic bottle and block the exhaust vent 7 that is not inside the plastic bottle, a hole-blocking sleeve 15 is slidably fitted on multiple exhaust pipes 6. A fixing strip 16 is fixedly installed on multiple hole-blocking sleeves 15. Two guide posts 17 are slidably installed on the top support plate 4. The bottom ends of the two guide posts 17 are fixedly connected to the fixing strip 16. Furthermore, a back-connecting plate 18 is fixedly installed on the top of the top support plate 4, and a screw 19 is threaded onto it. An mounting plate 20 is rotatably installed on one end of the screw 19. Two fastening rods 21 are fixedly installed on one side of the mounting plate 20. The ends of the two fastening rods 21 abut against the two guide posts 17 respectively. By rotating the screw 19, the fastening rods 21 are separated from the guide posts 17, thereby adjusting the height of the hole-blocking sleeve 15 and blocking the corresponding exhaust vent 7 according to actual needs. In addition, a blocking plate is fixedly installed on the top of each of the two guide posts 17 to prevent the guide posts 17 from detaching from the top support plate 4.
[0029] In the above method, in order to ensure that the mounting plate 20 can only move in a straight line, two limiting rods are slidably installed on the back plate 18, and the same-direction ends of the two limiting rods are fixedly connected to the mounting plate 20.
[0030] The working principle of the plastic bottle internal dryer provided by this utility model is as follows:
[0031] When it is necessary to dry the inside of the plastic bottle, first activate the output shafts of the two electric push rods 3 to extend and bring multiple exhaust pipes 6 to a high position. Then, take out multiple plastic bottles and place them in the corresponding placement slots 2 in sequence. Then, rotate the rotating shaft 11 clockwise to drive the bidirectional threaded sleeve 12 to rotate. At this time, the corresponding two linkage bars 13 move towards each other. When the linkage bars 13 contact the plastic bottle, they gradually move it towards the center of the placement slot 2, and finally restrict the multiple plastic bottles to the center position of each placement slot 2.
[0032] Then, the output shaft of the electric push rod 3 retracts, and multiple exhaust pipes 6 will descend and eventually enter the corresponding plastic bottles. At this time, observe the position of the exhaust holes 7 on the exhaust pipes 6. When some of the exhaust holes 7 have not entered the plastic bottles, the screw 19 can be turned counterclockwise to separate the two fastening rods 21 from the two guide posts 17. Then, the guide posts 17 can be moved up or down as needed to drive the hole-blocking sleeve 15 to rise or fall until all the exhaust holes 7 protruding from the plastic bottles are blocked. Then, the screw 19 is turned clockwise to re-tighten the guide posts 17 using the fastening rods 21.
[0033] Next, the hot air blower 8 is turned on, and the hot air it generates is guided into the ventilation pipe 5 through the air guide pipe 9 and into each exhaust pipe 6. Finally, it is blown into the plastic bottle through the exhaust hole 7 located inside the plastic bottle, thus achieving a rapid drying effect. After a period of time, the drying work is completed, and the hot air blower 8 can be turned off. Then, the output shaft of the electric push rod 3 is activated to extend and bring the exhaust pipe 6 out of the plastic bottle, so that the dried plastic bottle can be removed. Afterward, multiple plastic bottles are put back into the placement slot 2 to continue the hot air drying work for the next batch.
[0034] Compared with related technologies, the plastic bottle internal drying machine provided by this utility model has the following advantages:
[0035] Beneficial effects:
[0036] This utility model provides a plastic bottle internal drying machine. Through the provided exhaust pipe 6 and the exhaust hole 7 on the exhaust pipe 6, it can be smoothly inserted into the plastic bottle, and hot air is discharged into the plastic bottle through the exhaust hole 7, thus forming a hot air drying working state. Compared with traditional natural wind drying, this method is faster and significantly improves the production efficiency of plastic bottles, making it more suitable for large-scale production lines. Furthermore, the locking arc plate 14 and the large-diameter placement groove 2 enable this method to be applicable to the drying of plastic bottles of various diameters, thus having a wide range of applications.
