Technical Field
[0001] The utility model relates to the technical field of conveying and transferring equipment, in particular to a hopper structure of a bottle embryo basket loading machine. Background Art
[0002] After the preforms are produced by the injection molding production line, they need to be transported to the filling line. In the prior art, the preforms are loaded into baskets by placing the baskets directly at the end of the conveyor line. After the baskets are full, they are transported away. This method easily causes the preforms to be bumped and deformed due to the large drop. Therefore, it is very important to design a hopper that can transport the preforms into the baskets and then release them. This can reduce the drop height of the preforms and effectively solve the problem of bumping and deformation of the preforms. Utility Model Content
[0003] In view of the deficiencies in the prior art, the main purpose of the utility model is to provide a hopper structure of a preform basket loading machine that can realize the opening and closing of the hopper and can realize the automatic release of the preforms.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hopper structure of a preform basket loading machine, comprising a hopper frame with an opening at the top, a pneumatic opening and closing assembly being arranged at the bottom of the hopper frame, the pneumatic opening and closing assembly comprising two inclined bottom plates arranged at the bottom of the hopper by rotating through a rotating shaft, a telescopic cylinder capable of driving the inclined bottom plates to rotate being arranged on the side wall of the hopper frame, and an ultrasonic detection sensor being arranged on one side of the hopper frame.
[0005] Preferably, a connecting rod is provided on the outer side wall of each inclined bottom plate, and both ends of each connecting rod are respectively connected to a telescopic cylinder, and the telescopic cylinder is rotatably connected to the side wall of the hopper frame through a pin shaft.
[0006] Preferably, a middle plate is respectively provided at the bottom of the two inclined bottom plates, and a gap is provided between the two middle plates.
[0007] Preferably, extension guard plates are respectively provided on both sides of each inclined bottom plate.
[0008] Compared with the prior art, the utility model has the following advantages: its function is to drive the two inclined bottom plates to rotate through the action of the telescopic cylinder, thereby realizing the opening and closing of the hopper, and realizing the automatic release of the bottle preforms and the loading of the bottle preforms. The entire hopper structure can cooperate with the lifting mechanism to realize the release after the hopper is transported to the appropriate position, which can reduce the falling height of the bottle preforms and effectively solve the problem of the bottle preforms being bumped and deformed. The ultrasonic detection probe can detect the distance between the hopper and the top layer of the bottle preforms in the basket during the hopper's descent. When the set distance is reached, the pneumatic opening and closing component is activated, and the hopper releases the bottle preforms into the basket. It is ensured that the hopper releases the material at a set shorter distance. BRIEF DESCRIPTION OF THE DRAWINGS

The entire hopper structure can cooperate with the lifting mechanism to realize the release after the hopper is transported to the appropriate position, which can reduce the falling height of the preforms and effectively solve the problem of the preforms being bumped and deformed. The ultrasonic detection probe can detect the distance between the hopper and the top layer of the preforms in the basket during the hopper's descent. When the set distance is reached, the pneumatic opening and closing component is activated, and the hopper releases the preforms into the basket. It is ensured that the hopper releases the material only at the set shorter distance.
