[0025] Please refer to Figures 1 - 3 , a preform heating device, including a support plate 1 and an adjustable heating assembly. A top plate 2 and a protection box 3 are sequentially arranged on the top of the support plate 1. Support feet 4 are arranged at the bottom of the support plate 1. There are two support plates 1, and a rectangular groove with an open top is opened on the side close to each other. An adjustable heating assembly is arranged in the two rectangular grooves;
[0026] The adjustable heating assembly includes a moving plate 5, a connecting seat 6, a heating pipe 7 and a linkage module. The linkage module consists of a motor 10, a sprocket set, a rotating rod 9 and a guiding column 11. The motor 10 and the sprocket set are arranged inside the top plate 2. The rotating rod 9 is threadedly connected to the moving plate 5. The guiding column 11 is inserted into the moving plate 5. The moving plate 5 is bolt-fixed to the connecting seat 6. The heating pipe 7 is installed inside the connecting seat 6.
[0027] In this embodiment, the connecting seat 6 is composed of a first connecting seat 601 and a second connecting seat 602. The bottom of the first connecting seat 601 is open, and the heating pipe 7 is installed at its bottom opening. A heater is arranged inside the first connecting seat 601 and at the top of the heating pipe 7.
[0028] It should be noted that this split design of the connecting seat 6 not only facilitates the installation and positioning of the heating pipe 7, but also makes the maintenance and replacement of the heater simpler.
[0029] In this embodiment, slots are opened on both sides of the first connecting seat 601, and heat insulation plates 8 are bolt - fixed in the slots. There are two second connecting seats 602, which are respectively welded to the outer sides of both sides of the first connecting seat 601, and insertion blocks are arranged on the outer sides of the second connecting seats 602.
[0030] It should be noted that the heat insulation plates 8 are provided to reduce the heat loss during the heating process and improve energy efficiency. By bolting the heat insulation plates 8 in the slots of the first connecting seat 601, the stability and durability of the heat insulation effect can be ensured. The welding and insertion - block design of the second connecting seats 602 enhances the overall structural strength of the connecting seat 6, and also facilitates the insertion and fixation with the moving plate 5.
[0031] In this embodiment, the two second connecting seats 602 are respectively inserted into the two moving plates 5 through the insertion blocks, and are bolt - fixed after insertion. There are two rotating rods 9, which are respectively thread - connected to the two moving plates 5. Both ends of the rotating rods 9 are rotatably connected to the support plate 1 and the top plate 2 through bearings.
[0032] It should be noted that this way of insertion plus bolt - fixation not only ensures the firm connection between the connecting seat 6 and the moving plate 5, but also facilitates disassembly and replacement when needed.
[0033] In this embodiment, first sprockets are bolt - fixed to the outer parts of the two rotating rods 9 near the top. The motor 10 is located in the protection box 3, and a rotating rod is bolt - fixed to its output end. The end of the rotating rod is rotatably connected to the top plate 2 through a bearing.
[0034] In this embodiment, a second sprocket is bolt - fixed to the outer part of the rotating rod. A chain is commonly sleeved on the outer parts of the two first sprockets and the second sprocket. The two rotating rods 9 have the same size and the same thread direction.
[0035] It should be noted that the two rotating rods 9 have the same size and the same thread direction, which can ensure that during the transmission of the sprocket group, the two rotating rods 9 can rotate synchronously, thereby driving the two moving plates 5 to move up and down synchronously, and realizing the precise adjustment of the height of the heating pipe 7.
[0036] Working principle:
[0037] The motor 10 is located inside the protection box 3. Its output end drives the rotating rod to rotate. The rotating rod is rotatably connected to the top plate 2 through a bearing, and a second sprocket is fixed on its outer side. The second sprocket is connected to the first sprockets at the near-top ends of two screw rods 9 through a chain, forming a sprocket group transmission system. Both ends of the screw rod 9 are respectively rotatably connected to the support plate 1 and the top plate 2 through bearings, and the screw rod 9 is threadedly connected to the moving plate 5. When the motor 10 is started, through the transmission of the sprocket group, the screw rod 9 rotates, thereby driving the moving plate 5 to move up and down under the guidance of the guide post 11. The moving plate 5 is fixed to the connecting seat 6 through bolts. The connecting seat 6 is composed of a first connecting seat 601 and a second connecting seat 602. The insertion block on the outer side of the second connecting seat 602 is inserted into and bolted to the moving plate 5. The bottom of the first connecting seat 601 is open, and the heating pipe 7 is installed here, and a heater is provided at the top inside it. As the moving plate 5 moves up and down, the height of the heating pipe 7 is also adjusted accordingly to meet the heating requirements of different preforms. At the same time, heat insulation plates 8 are bolted in the grooves on both sides of the first connecting seat 601 to improve energy efficiency and protect the surrounding components.
[0038] Advantageous effects:
[0039] For this preform heating device, the motor 10 drives the sprocket group to rotate, thereby driving the screw rod 9 to rotate, so that the moving plate 5 threadedly connected to the screw rod 9 moves up and down under the guidance of the guide post 11, thus adjusting the height of the heating pipe 7. The connecting seat 6 adopts a split design, which is convenient for the disassembly and maintenance of the heating pipe 7. In addition, the device is also provided with heat insulation plates 8 to improve energy efficiency and protect the surrounding components.
[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
