DETAILED DESCRIPTION

[0022] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0023] An energy-saving preheating bottle machine, such as Figure 1 and Figure 2, including a frame 1, a heating channel 11 arranged on the frame 1, and a conveying device 12 for conveying and outputting the bottle body into the heating channel 11, a blowing channel for heating the bottle mouth is arranged in the heating channel 11, and two blowing channels are arranged and distributed on both sides of the bottle body. The structure of the blowing channel can be a blowing channel structure in a new type of preheating bottle machine disclosed in the patent with announcement number CN114229763B, which will not be repeated here. The frame 1 is provided with an arc channel connected to the conveying device 12 at the inlet 112 of the heating channel 11 13, a conveyor belt 14 perpendicular to the length direction of the conveyor device 12 is provided at one end of the arc channel 13 away from the conveying device 12, and an arc cover 131 and a protective cover 141 covering the arc channel 13 and the conveying belt 14 are respectively provided on the frame 1, and the lower end surfaces of the arc cover 131 and the protective cover 141 are in contact with the upper end surfaces of the arc channel 13 and the conveying belt 14, and the contact means that the arc cover 131 and the protective cover 141 are not affected by the transmission of the arc channel 13 and the conveying belt 14, and only play the role of covering the bottle body for preheating and guiding.

[0024] like Figure 1 and Figure 2 The setting of the arc channel 13 allows the heat emitted from the inlet 112 of the heating channel 11 to preheat the arc channel 13 and the bottles on the conveyor belt 14, and the arc channel 13 increases the path of the hot air when it flows in the arc channel 13, so that the heat at the inlet 112 of the heating channel 11 is in contact with the bottle to be preheated for a long time, reducing the heat waste at the inlet 112 of the heating cover 111 and saving energy. The setting of the conveyor belt 14 changes the transmission direction of the bottle. The conveyor belt 14 and the conveying device 12 are L-shaped, which reduces the occupied area. When the bottle is conveyed into the heating cover 111, the bottle first passes through the protective cover 141 on the conveyor belt 14, and then passes through the arc cover 131 of the arc channel 13, and is gradually preheated.

[0025] like Figure 1 and Figure 2 The structure of the heating channel 11 can be a heating channel 11 structure in a new type of preheating bottle machine disclosed in the patent with announcement number CN114229763B, that is, the heating channel 11 includes a heating cover 111 arranged on the frame 1, and the two ends of the heating cover 111 are respectively provided with an inlet 112 and an outlet 113 for the conveying device 12 and the bottle body to move out and in; the reason why the arc channel 13 and the conveyor belt 14 are not arranged at the outlet 113 is because the bottle body moved out of the preheating bottle machine will enter the next process.

[0026] like Figure 1 and Figure 3The conveying device 12 includes a transmission belt 121 with one end arranged outside the inlet 112 of the heating cover 111 and the other end passing through the heating cover 111 and passing through the outlet 113 of the heating cover 111. The transmission belt 121 transmits the bottle body in and out of the heating cover 111. Both ends of the transmission belt 121 are provided with H-shaped support frames 122 supported on the ground. The support frames 122 are placed vertically, and pulleys are rotatably connected on the opposite mouth walls of the upper end opening of the support frame 122. The transmission belt 121 is wound around the pulley, and one of the support frames 122 is provided with a motor (not shown in the figure) for driving the pulley to rotate. The inner wall of the cabinet is provided with baffles located on both sides of the transmission belt 121 at one end of the transmission belt 121 located in the cabinet, and the baffles do not extend out of the inlet 112 of the heating cover 111.

[0027] like Figure 1 and Figure 2 The protective cover 141 above the conveyor belt 14 is distributed along the length direction of the conveyor belt 14. The arc channel 13 includes a plurality of pillars 132 placed on the ground. The upper ends of the pillars 132 are connected by a fixing plate 133. A circular groove 134 is provided on the upper end surface of the fixing plate 133. The fixing plate 133 is rotatably connected with a turntable 135 in the circular groove 134. At this time, one side of the fixing plate 133 is parallel to and close to the side of the transmission belt 121, and the other side is parallel to and close to the side of the conveyor belt 14. The upper end surface of the turntable 135 is flush with the upper end surface of the fixing plate 133. A motor 136 for driving the turntable 135 to rotate is provided at the bottom of the fixed plate 133. The upper end surfaces of the fixed plate 133 are flush with the upper end surfaces of the transmission belt 121 and the conveyor belt 14. One end of the arc cover 131 is fixed to the outer wall of the heating cover 111 and is connected to the inlet 112 of the heating cover 111, and the other end is connected to the protective cover 141 on the conveyor belt 14. The longitudinal sections of the protective cover 141 and the arc cover 131 are both inverted U-shaped, and the curvature of the arc cover 131 allows the bottle body to be transmitted from the transmission belt 121 to the disk surface of the turntable 135, and then to the conveyor belt 14.

[0028] like Figure 1 and Figure 3 A closing plate 142 extending downward is provided at one end of the protective cover 141 on the conveyor belt 14 away from the arc cover 131 , and a gap exists between the lower end surface of the closing plate 142 and the conveyor belt 14 . A moving-in hole 143 for the bottle body to move into the protective cover 141 is provided on the closing plate 142 .

[0029] like Figure 1 and Figure 3, a protective cover 141 extends from one end of the conveyor belt 14, and a storage board 15 is distributed on both sides of the conveyor belt 14 at the extended end. The function of the storage board 15 is to place the bottle body on the storage board 15 in advance. The lower ends of the two storage boards 15 are provided with a plurality of vertical rods 151 extending to the ground and fixed on the ground. The length direction of each storage board 15 is distributed along the length direction of the conveyor belt 14. The storage board 15 is provided with a moving part for moving the bottle body placed on the storage board 15 to the conveyor belt 14. At this time, the moving part moves the bottle body on the storage board 15 to the conveyor belt 14, and the bottles on both sides of the storage board 15 are placed in a staggered manner.

[0030] like Figure 3 and Figure 4 The movable member includes a horizontally distributed guide rail 152 arranged on the opposite side of the two storage plates 15. The height of the guide rail 152 is higher than the height of the storage plate 15. Both ends of each guide rail 152 are provided with a connecting rod 153. The end of the connecting rod 153 away from the guide rail 152 is fixed on the vertical rod 151. Slide blocks 154 are slidably connected to the two guide rails 152. The slide blocks 154 are located on the side opposite to the two guide rails 152. The upper and lower ends of the two slide blocks 154 extend out of the upper and lower ends of the guide rails 152, and the parts extending out of the upper and lower ends of the guide rails 152 are provided with fixed blocks 155 that continue to extend in the opposite side directions of the two guide rails 152. A U-shaped guide bar 156 is provided between the fixed blocks 155 on the two guide rails 152. The two vertical edges of the guide bar 156 are respectively connected to the fixed blocks 155 on the two guide rails 152. The edge located between the two vertical edges is an arc edge. A power member for driving the slide blocks 154 to move is provided on the guide rail 152.

[0031] like Figure 3 and Figure 4 At this time, the power member drives the slider 154 to move, thereby driving the guide bar 156 to move, so that the two ends of the guide bar 156 are close to the bottle body on the storage plate 15, so that the bottle body slides into the arc edge from the opposite ends of the guide bar 156. When the bottle body is located at the most curved part of the arc edge, the bottle body is located on the conveyor belt 14, so that the bottle body is sent from the storage plate 15 to the conveyor belt 14. The speed of the guide bar 156 is less than the speed of the conveyor belt 14 to transport the bottle body, so that after the bottle body is guided to the conveyor belt 14, the conveyor belt 14 accelerates the transmission speed of the bottle body, so that the bottle body moves away from the guide bar 156.

[0032] like Figure 3 and Figure 4The power part includes a long strip chute 16 provided on the opposite side of the two guide rails 152, and a slider 154 is slidably connected in the chute 16. A screw rod 161 is rotatably connected to the opposite groove wall of one of the chute 16, and the screw rod 161 passes through the slider 154 and is threadedly connected to the slider 154. A second motor 162 is provided on the guide rail 152 to drive the screw rod 161 to rotate. The second motor 162 drives the screw rod 161 to rotate, so that the screw rod 161 drives the slider 154 to rotate in the chute 16, so as to drive the guide bar 156 to move.

[0033] like Figure 3 and Figure 4 One end of the guide bar 156 extends out of the position connected with the fixed block 155, so that the guide bar 156 can contact the side wall of the fish bottle body, and the width of the side of the guide bar 156 in contact with the guide rail 152 is greater than the width of the guide rail 152. The upper and lower end surfaces of the guide rail 152 are provided with moving grooves 163 distributed along the length direction of the guide rail 152. The guide bar 156 is provided with a moving block 164 sliding in the moving groove 163 on the side facing the guide rail 152. The material of the guide bar 156 is a flexible plastic, and the fixed block 155 is connected to the moving block 164. At this time, the moving block 164 makes the guide bar 156 slide on the guide rail 152 stably and is convenient for connecting with the fixed block 155.

[0034] like Figure 3 and Figure 4 The fixed block 155 is detachably connected to the moving block 164. The upper end surface of the fixed block 155 is threadedly connected with a screw 165, and the screw 165 passes through the fixed block 155 and is threadedly connected to the moving block 164. At this time, it is convenient to disassemble and install the fixed block 155 and the moving block 164.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
