[0017] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom" and "top", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figures 1 to 4As shown, a preform feeding device comprises a bottle blowing machine body 1, the bottle blowing machine body 1 is an existing bottle blowing machine, a support plate 11 is fixedly arranged inside the bottle blowing machine body 1, a support disc 13 is fixedly arranged on the top of the support plate 11, two symmetrical half molds 12 are arranged on the top of the support disc 13, and a support platform 14 is arranged between the two half molds 12; through the arrangement of the bottle blowing machine body 1, the heated object can be blown into the two half molds 12, and then the bottle preform can be formed on the support platform 14.

[0019] The support platform 14 is fixedly arranged at the top of the support plate 13, and a driving mechanism 2 for driving the two half molds 12 to open or close is arranged on the support plate 13. The driving mechanism 2 includes a motor 21 fixedly arranged on one side of the inner wall of the bottle blowing machine body 1. The top of the support plate 13 is rotatably connected with a rotating shaft 1 22 and a rotating shaft 2 23. The rotating shaft 1 22 and the rotating shaft 2 23 are symmetrical and are respectively fixed with a gear 1 24 and a gear 2 25. The motor 21 is fixedly arranged at the top of the rotating shaft 1 22. The outer walls of the rotating shaft 1 22 and the rotating shaft 2 23 are fixed with connecting rods 26. The two connecting rods 26 are respectively fixed to the outer walls of the two half molds 12. Two symmetrical slide grooves 27 are arranged at the top of the support plate 13. The two slide grooves 27 are slidably connected with sliding Block 28, the size of the slide 27 is larger than the slider 28, and the two sliders 28 are respectively fixed to the bottom ends of the two half molds 12; by starting the motor 21, the shaft 1 22 and the gear 1 24 can be driven to rotate respectively, and when the gear 1 24 rotates, the gear 2 25 and the shaft 2 23 can be driven to rotate respectively. Since the rotation directions of the shaft 1 22 and the shaft 2 23 are opposite, when both rotate, the two half molds 12 can be driven to approach or separate from each other respectively. When the two half molds 12 move, the two sliders 28 can be driven to slide inside the two slide grooves 27 respectively. Since the size of the slide groove 27 is larger than the slider 28, when the half mold 12 is in an arc movement, the slider 28 can be prevented from colliding with the inner wall of the slide groove 27.

[0020] The bottle blowing machine body 1 is provided with a pushing mechanism 3 for pushing the bottle preform, and the pushing mechanism 3 includes a cylinder 31 fixedly mounted on the outer wall of the bottle blowing machine body 1, a piston rod of the cylinder 31 passes through the outer wall of the bottle blowing machine body 1 and a pushing block 32 is fixedly mounted on the piston rod, and the pushing block 32 is arranged in an arc shape; the pushing block 32 can be driven to move toward the bottle preform by starting the cylinder 31 until the bottle preform is pushed.

[0021] The support plate 13 and the support plate 11 are both penetrated with a through groove 15, and a discharge plate 16 is fixedly arranged at the bottom end of the support plate 11. A groove 17 is penetrated at one side of the outer wall of the bottle blowing machine body 1, and one end of the discharge plate 16 is located in the groove 17 and a discharge groove 161 is opened at the top. The discharge plate 16 and the discharge groove 161 are both arranged at an angle. A collecting box 18 is arranged at one side of the bottle blowing machine body 1, and the bottom end of the discharge plate 16 is located above the collecting box 18. A rubber pad 181 is arranged at the bottom end of the collecting box 18. When the pushing block 32 pushes the preform to the through groove 15, the preform can pass through the support plate 13 and the support plate 11 respectively, and fall into the discharge groove 161 on the discharge plate 16. Since the discharge plate 16 and the discharge groove 161 are both arranged at an angle, the preform can fall downward into the collecting box 18. The arrangement of the rubber pad 181 can prevent the preform from directly colliding with the bottom end of the collecting box 18 when it falls.

[0022] Working principle: When the bottle blowing machine body 1 blows the heated article into the two half molds 12, a preform can be formed inside the two half molds 12. Then the motor 21 of the driving mechanism 2 is started, which can drive the shaft 1 22 and the gear 1 24 to rotate respectively. When the gear 1 24 rotates, it can drive the gear 2 25 and the shaft 2 23 to rotate respectively. Since the rotation directions of the shaft 1 22 and the shaft 2 23 are opposite, when both rotate, they can drive the two half molds 12 to separate from each other, and can not only drive the two sliders 28 to move in the two The sliding inside the slide groove 27 can also make the two half molds 12 in an open state, which is convenient for the subsequent pushing of the pushing mechanism 3. After that, the cylinder 31 of the pushing mechanism 3 is started to drive the pushing block 32 to move toward the bottle embryo until the bottle embryo is pushed to the through groove 15. The bottle embryo can pass through the support plate 13 and the support plate 11 respectively, and fall into the discharge groove 161 on the discharge plate 16. Since the discharge plate 16 and the discharge groove 161 are both inclined, the bottle embryo can fall downward into the collection box 18, and finally the function of convenient unloading can be realized.

[0023] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
