DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] A bottle preheating machine with an adjustable air duct position structure, such as Figure 1 and Figure 2 , including a frame 1 and a heating cover 11 provided on the frame 1 and a conveying device for conveying bottles into and out of the heating cover 11, the conveying device including but not limited to the conveying device in a new type of preheating bottle machine of application number , which is an existing structure and will not be described in detail here, the frame 1 can be a plurality of vertical rods provided at the lower end of the heating cover 11, the purpose of which is to support the heating cover 11 off the ground;

[0026] like Figure 1 and Figure 2 A hot air blower 12 is provided on the outer wall of the upper end of the heating cover 11, and a blowing duct 13 for heating the bottle body and the bottle mouth is provided in the heating cover 11. The blowing duct 13 is provided with two and distributed on both sides of the bottle body. The blowing duct 13 is a vertically distributed plate with a hollow cavity. The hollow cavity is located in the middle and lower part of the blowing duct 13, and the length of the blowing duct 13 is distributed along the transmission direction of the bottle body. A long strip-shaped air outlet 131 is provided on the side of the blowing duct 13 facing the bottle body. At this time, the blowing port 162 is distributed toward the bottle mouth of the bottle body, which is convenient for entering the heating cover. The bottle bodies and mouths in the heating hood 11 are heated. A first hose 132 communicating with the hollow cavity is provided above each blowing channel 13. A connecting pipe 133 is provided on the inner wall of the upper end of the heating hood 11. The connecting pipe 133 connects the first hose 132 and the hot air blower 12. That is, the connecting pipe 133 is fixed to the inner wall of the heating hood 11, but one end is connected to the first hose 132, and the other end extends out of the outer wall of the heating hood 11 and communicates with the hot air blower 12. The heating hood 11 is provided with a power element that drives the two blowing channels 13 to move horizontally and vertically. In addition, the portion of the connecting pipe 133 outside the heating hood 11 is provided with a shut-off valve and a pressure regulating valve (not shown in the figure) to facilitate the control of the air volume delivered within the connecting pipe 133.

[0027] like Figure 1 and Figure 2 The conveying device conveys the bottle body into the heating cover 11. During the conveying process in the heating cover 11, the hot air from the hot air blower 12 is conveyed to the blowing channel 13 through the connecting pipe 133, and then blown to both sides of the bottle mouth of the bottle body through the air outlet 131 of the blowing channel 13 to heat it. When the conveying device conveys bottles of different specifications, the height of the blowing channel 13 and the horizontal distance between the two blowing channels 13 are adjusted by the power parts to expand the applicable range and dry bottles of different specifications.

[0028] like Figure 2 and Figure 4 , the power part includes two lifting plates 14 vertically slidably connected to the opposite inner walls of the heating cover 11, the two lifting plates 14 are distributed along the length of the blowing duct 13, and the two ends of the two lifting plates 14 are connected by guide rods 141 respectively, and the two guide rods 141 pass through the two ends of the two blowing ducts 13 respectively, that is, the blowing duct 13 can slide on the two guide plates, and a driving rod 142 is rotatably connected between the two lifting plates 14, one of the lifting plates 14 is provided with a motor 143, the rotating shaft of the motor 143 is horizontally distributed and coaxially fixedly connected to a driving gear 144, and a driven gear 145 meshing with the driving gear 144 is provided on the outer wall of the driving rod 142, and the driving rod 142 passes through the side walls of the two blowing ducts 13 and the driving rod The outer wall of 142 is provided with a reverse thread which is respectively threadedly connected to the two blowing ducts 13. The reverse thread, that is, the driving rod 142 is provided with two threads with different rotation directions, so that when the driving rod 142 rotates in one direction, the two blowing ducts 13 are moved closer to each other or transported due to the reverse thread. The driven gear 145 is located between the blowing duct 13 and the lifting plate 14. The upper ends of the two lifting plates 14 are connected by an inverted U-shaped pull rod 146. The upper end of the outer wall of the heating cover 11 is provided with an electric pole 147 for driving the pull rod 146 to rise and fall, that is, the electric pole 147 is fixed to the upper end of the outer wall of the heating cover 11, but the rod part of the electric pole 147 enters the heating cover 11 and is fixed to the upper end of the pull rod 146, so that the electric pole 147 and the hot air blower 12 are staggered.

[0029] like Figure 2 and Figure 4 The working principle of the power part is: when the position of the blowing duct 13 needs to be adjusted, the motor 143 drives the driving gear 144 to rotate, and then drives the driven gear 145 and the driving rod 142 to rotate. The driving rod 142 drives the two blowing ducts 13 to move closer to or away from each other through the reverse thread. At this time, the guide rod 141 guides the movement of the blowing duct 13, which makes it easy to adjust the horizontal distance between the two blowing ducts 13, suitable for heating bottle bodies and bottle mouths of different widths. The electric pole 147 drives the pull rod 146 to move up and down, which is convenient for driving the two lifting plates 14 to move up and down. At this time, the lifting plate 14 drives the blowing duct 13 to move up and down together through the guide rod 141 and the driving rod 142, which is convenient for heating bottle bodies and bottle mouths of different heights. In addition, the lifting plate 14 is detachably connected to a heat insulation cover (not shown in the figure) that covers the outer wall of the motor 143. The rotating shaft of the motor 143 passes through the heat insulation cover and is rotatably connected to the cover wall of the heat insulation cover. The driving gear 144 is located outside the heat insulation cover. In addition, the side wall of the heating cover 11 is also provided with an inspection door 111 for placing and inspecting the motor 143.

[0030] like Figure 2 and Figure 4The air duct 13 is provided with air guide plates 15 on both sides of the upper and lower sides of the air outlet 131 to guide the wind toward the bottle body. At this time, the function of the air guide plates 15 is to guide the hot air toward the bottle body and the bottle mouth.

[0031] like Figure 3 and Figure 4 and Figure 5 In order to heat the top of the bottle mouth of the bottle body and speed up the heating efficiency, the two blowing ducts 13 are provided with mutually staggered insertion rods 16 at both ends of the opposite side, and a top plate 161 is placed between the two blowing ducts 13. The top plate 161 is distributed in the length direction of the smoke blowing duct 13, and each insertion rod 16 is inserted into the two ends of the top plate 161 and is located on the outer walls of the two guide rods 141. A ventilation cavity distributed along the length direction of the top plate 161 is provided inside the top plate 161, and a long strip blowing port 162 facing the top of the bottle body is opened on the lower end surface of the top plate 161. A second hose 163 connected to the ventilation cavity is provided on one side of the top plate 161, and the end of the second hose 163 away from the top plate 161 is connected to the connecting pipe 133. A limiting member is provided on the top plate 161 so that the top plate 161 is always located directly above the bottle mouth of the bottle body. At this time, the function of the limiter is to fix the position of the top plate 161, so that the blowing port 162 on the top plate 161 can deliver hot air directly above the bottle mouth of the fragrance bottle. The setting of the insertion rod 16 makes it convenient for the two blowing ducts 13 to move closer to or away from each other, while the top plate 161 remains in the position directly above the bottle mouth and does not affect the movement of the blowing duct 13.

[0032] like Figure 3 and Figure 4 and Figure 5 The limiting member includes slide rods 165 arranged on both sides of the length direction of the top plate 161. The longitudinal section of the heating cover 11 is an inverted U-shaped cover body, and both ends are closed. Both closed ends are provided with inlets and outlets 164 for the bottles and the conveying device to enter and exit. The ends of the two slide rods 165 away from the top plate 161 are respectively slidably connected to the inner wall of the heating cover 11 with the inlet and outlet 164.

[0033] like Figure 3 and Figure 4 and Figure 5 At this time, when the power member drives the blowing duct 13 to rise and fall, the top plate 161 slides on the inner wall of the heating cover 11 via the slide rod 165, thereby facilitating the rise and fall of the blowing duct 13. However, when the horizontal distance between the two blowing ducts 13 is adjusted, the top plate 161 is always located directly above the bottle mouth due to the arrangement of the slide rod 165. In order to facilitate the sliding of the slide rod 165 on the inner wall of the heating cover 11, the slide rod 165 can be arranged in a Z shape, so that the lower end of the slide rod 165 is fixed to the top plate 161, and the higher end of the slide rod 165 slides on the inner wall of the heating cover 11.

[0034] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
