Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

The bottle blank 100 shown in fig. 1 comprises a blank tube 101, a handle 102 and a bottle mouth 103, wherein one end of the handle 102 is connected with the blank tube 101 into a whole, the other end of the handle 102 is not connected with the blank tube 101 and is in a suspended state, the blank tube 101 of the bottle blown by the bottle blank is blown to form a bottle body 104, and the states of the handle 102 and the bottle mouth 103 are basically kept unchanged as shown in fig. 2.

The existing bottle blank heating device can heat the blank tube 101 and the handle 102 together, because the handle 102 is heated, and one end of the handle 102 is in a suspended state, the handle 102 can deform, so that the handle 102 cannot be embedded into a corresponding groove of a bottle blowing mold, and the bottle blowing mold cannot be closed to blow bottles.

In order to prevent the handle 102 from being heated and deformed, as shown in fig. 3 to 5, the preform heating apparatus according to an embodiment of the present invention includes a chamber 1, a top cover 2, and a plurality of heating lamps 3, as shown in fig. 6, a first receiving chamber 11 and a second receiving chamber 12 are formed in the chamber 1, the first receiving chamber 11 is cylindrical, the second receiving chamber 12 is connected to a side surface of the first receiving chamber 11, as shown in fig. 7, the heating lamps 3 include a lamp tube 31 and a lamp holder 32, the lamp tube 31 includes an arc portion 311 and two connecting portions 312, one end of the connecting portion 312 is connected to the lamp holder 32, the other end of the connecting portion 312 is connected to one end of the arc portion 311, the arc portion 311 is disposed in the first receiving chamber 11, the connecting portions 312 and the lamp holder 32 are disposed in the second receiving chamber 12, the top cover 2 is disposed on a top of the chamber 1, a first through hole 21 is formed in the top cover 2, the preform 101 of the preform 100 can be inserted into the first receiving chamber 11 through the first through hole 21 and surrounded by the arc portion 311, the radius of the first accommodating cavity 11 is smaller than the distance between the end of the handle 102 of the bottle blank 100 away from the tube 101 and the central axis of the tube 101, so that the handle 102 cannot be placed in the first accommodating cavity 11.

The bottle blank heating device of the embodiment has the cavity 1 with a specific size, so that the blank tube 101 of the bottle blank 100 can be inserted into the first accommodating cavity 11 through the first through hole 21 on the top cover 2 and surrounded by the heating lamp 3, the handle 102 of the bottle blank 100 cannot be placed inside the cavity 1, and the heating lamp 3 only heats the blank tube 101, so that the handle 102 is prevented from being deformed by heat, and conditions are created for the smooth blowing of the subsequent bottle blank 100. The shape of the cavity 1 is adapted to the shape of the heating lamp 3, the arc portion 311 of the heating lamp 3, which is responsible for heating the embryonic tube 101, is arranged in the first accommodating cavity 11, the connecting portion 312 of the heating lamp 3 and the lamp holder 32 are arranged in the second accommodating cavity 12, and the space in the cavity 1 is fully utilized, so that the cavity 1 has a compact volume, occupies a small space, and is convenient to install.

As shown in fig. 4, 5 and 8, the bottle blank heating device further includes a plurality of heat insulation rings 6, and the heat insulation rings 6 can be placed between two adjacent lamps 31, so that the heat insulation rings 6 surround the circumference of the circular arc portion 311. The heat-insulating ring 6 can block the light emitted from the lamp 31 from irradiating the inner wall of the cavity 1, and reflect the light back to the heating area of the first accommodating cavity 11, so as to improve the heating efficiency of the blank tube 101.

Specifically, two heat insulation rings 6 can be placed between two adjacent lamps 31, as shown in fig. 9, a notch 61 is formed on the heat insulation ring 6, and the two heat insulation rings 6 are stacked together, so that the two notches 61 are combined to form a hole for the lamp 31 to pass through. By controlling the distance between two adjacent lamp tubes 31, two heat insulation rings 6 stacked together can be just clamped between the two lamp tubes 31, and the heat insulation rings 6 can not easily fall out from between the lamp tubes 31.

Further, the heat insulation ring 6 is spaced from the inner wall of the chamber 1, so that a heat insulation cavity 111 is formed between the heat insulation ring 6 and the chamber 1. The heat insulation cavity 111 belongs to a part of the first accommodating cavity 11 and is located at the edge of the first accommodating cavity 11, and the heat insulation cavity 111 prevents the heat of the heat insulation ring 6 from being transferred to the cavity 1 through direct heat conduction, so that the temperature of the cavity 1 is not too high, and the handle 102 located outside the cavity 1 can be protected from being deformed due to high temperature.

Furthermore, the bottle blank heating device further comprises a bottom plate 7 and an exhaust pipe 8, the bottom of the cavity 1 is arranged on the bottom plate 7, the exhaust pipe 8 is detachably connected with the bottom plate 7 through a second screw 9, a second through hole (not shown in the figure) is formed in the bottom plate 7, and the exhaust pipe 8 penetrates through the second through hole and is inserted into the first accommodating cavity 11. In the process that the germ 101 is heated by the heating lamp 3, the outside air needs to be introduced to cool the germ 101 so as to avoid the high temperature of the germ 101, the exhaust pipe 8 is used for connecting the fan, so that the inside of the first accommodating cavity 11 forms negative pressure, and the outside air continuously flows into the inside of the first accommodating cavity 11.

As shown in fig. 4, a gap 13 is formed between the bottom of the top cover 2 and the top of the chamber 1, the gap 13 is communicated with the heat insulating chamber 111, and the heat insulating chamber 111 is communicated with the exhaust pipe 8. Specifically, a plurality of third through holes 81 are formed in the exhaust pipe 8, the third through holes 81 enable the exhaust pipe 8 to be communicated with the heat insulation cavity 111, and outside air enters the heat insulation cavity 111 through the gap 13 and then enters the inside of the exhaust pipe 8 through the third through holes 81. Therefore, an air curtain surrounding the heat insulating ring 6 is formed in the heat insulating cavity 111, which can take away more heat from the surface of the heat insulating ring 6, and avoid the temperature of the inner wall of the cavity 1 from being too high to affect the handle 102.

As shown in fig. 6, further, the side surface of the chamber body 1 is provided with air inlet holes 14, and the air inlet holes 14 are communicated with the second accommodating chamber 12. The outside air can enter the cavity 1 from the air inlet 14 besides entering the cavity 1 from the gap 13, and the outside air can enter the cavity 1 from the air inlet 14, so as to cool the connecting portion 312 of the lamp tube 31 and the lamp holder 32, thereby preventing the lamp holder 32 from being damaged due to overheating, and enabling the hot air in the cavity 1 to be discharged from the exhaust tube 8 only, and not to leak out from other places to affect the handle 102 of another bottle blank 100 on the adjacent bottle blank heating device.

As shown in fig. 4 and 5, a first cooling cavity 15 is arranged in the cavity 1, a first water inlet 16 and a first water outlet 17 are arranged on the surface of the cavity 1, and both the first water inlet 16 and the first water outlet 17 are communicated with the first cooling cavity 15. The cavity 1 has a double-layer structure, cooling water flows out from the first water outlet 17 after being introduced into the first cooling cavity 15 from the first water inlet 16, the first water inlet 16 is arranged at the lower part of the side surface of the cavity 1, the first water outlet 17 is arranged at the upper part of the side surface of the cavity 1, and the cooling water can further reduce the temperature of the cavity 1, so that the handle 102 outside the cavity 1 cannot deform due to high temperature.

As shown in fig. 8, a second cooling chamber (not shown in the figure) is arranged in the top cover 2, a second water inlet 22 and a second water outlet 23 are arranged on the surface of the top cover 2, and both the second water inlet 22 and the second water outlet 23 are communicated with the second cooling chamber. The handle 102 has a portion located directly above the top cap 2 and the spout 103 is also located directly above the top cap 2, which can affect the handle 102 and the spout 103 if the top cap 2 is at an excessive temperature. Therefore, it is necessary to cool the top cover 2 so that the temperature of the top cover 2 is not excessively high.

As shown in fig. 4 and 5, the central axis of the tubular blank 101 inserted into the first accommodating cavity 11 coincides with the central axis of the first accommodating cavity 11, so that the tubular blank 101 is located in the middle of the first accommodating cavity 11, and the distances from the circular arc portion 311 to all positions on the surface of the tubular blank 101 are substantially the same, so that the tubular blank 101 can be uniformly heated. When the blank 101 is heated, the blank 101 can also be rotated in the first receiving chamber 11 by rotating the mouth 103 in order to heat the blank 101 uniformly.
