[0001] The invention relates to the production of infusion bottles, in particular to an automatic steering device for large infusion bottles which can automatically adjust the angle of the large infusion bottles and meet the cleaning requirements of bottle washing equipment. Background Art

[0002] At present, the production process of conventional large infusion products includes several steps such as water preparation, bottle washing, stopper processing, polyester film processing, ingredient preparation, filling, capping, sterilization, light inspection and labeling packaging. In the bottle washing process, the cross-section of the empty large infusion bottle is elliptical. After being produced by the bottle blowing equipment, it is handed over to the handover fingers of the bottle washing equipment through the handover fingers of the bottle blowing equipment, and is sent to the bottle washing equipment for cleaning by the handover fingers of the bottle washing equipment. However, the large infusion bottle received by the bottle washing equipment has an elliptical cross-section with the short axis direction parallel to the movement direction of the handover fingers, and the long axis direction perpendicular to the movement direction of the handover fingers. The existing bottle washing equipment needs to rotate the large infusion bottle 90°, that is, the long axis of the elliptical cross-section of the large infusion bottle is parallel to the movement direction of the handover fingers, and the short axis is perpendicular to the movement direction. Therefore, it is necessary to adjust the angle of the large infusion bottle during the operation of the handover fingers of the bottle washing equipment to facilitate cleaning.

The automatic steering device is characterized in that it comprises a bottle calibration bracket and a handover finger, the handover finger is an array, and is equidistantly installed on the running track and moves with the running track; the bottle calibration bracket is fixed on the frame at the bottle inlet of the bottle washing equipment, and the handover finger passes through the bottle calibration bracket during operation; wherein:

[0006] The handover finger includes a finger substrate, a movable finger and a spreading device. The finger substrate is fixedly installed on the running track and slides with the running track. The middle of the finger substrate and the movable finger are connected by a rivet. The movable finger rotates around the rivet. The finger substrate and the front end of the movable finger are both provided with an arc-shaped notch. The arc-shaped notch of the finger substrate and the arc-shaped notch of the movable finger form an arc-shaped supporting area to clamp the bottleneck of the large infusion bottle; the spreading device includes a circular pulley, an elliptical pulley, a connecting rod, a reset spring and a spreading rod. The circular pulley is arranged on the outside of the handover finger, located behind the running direction of the handover finger, and higher or lower than the handover finger. The finger, a circular pulley is provided with a circular hole at the center, the elliptical pulley is provided between the finger substrate and the movable finger, and is located in front of the connecting rivet, and a circular hole is provided on the circular surface of the elliptical pulley; the connecting rod is fixed on the finger substrate and rotates around the fixed point, and axles are provided at both ends of the connecting rod, the axle at the front end of the connecting rod is installed in the circular hole on the circular surface of the elliptical pulley, and the axle at the rear end of the connecting rod is installed in the circular hole at the center of the circular pulley; the expansion rod is installed on the bottle calibration bracket, and its height is the same as that of the circular pulley; the reset spring is provided at the rear end of the intersection finger, one end of the reset spring is connected to the tail of the finger substrate, and the other end is connected to the tail of the movable finger;

[0007] The bottle calibration bracket includes a bottleneck slide, a bottle calibration frame and a bottle calibration plate. The bottle calibration frame is a rectangular frame, the interior of the rectangular frame is an adjustment area, the top frame is fixed to the bottom of the frame, the upper half of the inner frame is open, and the lower half is located inside the lower part of the running track; the bottle calibration plate is vertically fixed to the inner wall of the lower half of the inner frame of the bottle calibration frame, and the front end of the inner wall of the bottle calibration plate is set as an arc surface, which gradually thickens from the bottle inlet end to the bottle outlet end; the bottleneck slide is two parallel steel pipes, which are horizontally fixed below the top frame of the bottle calibration frame, and its height is between the handover finger and the protrusion below the bottle mouth of the large infusion bottle;

[0008] The support rod is horizontally fixed below the top frame of the bottle calibration frame or outside the inner frame, parallel to the running track; the horizontal distance from the outer wall of the support rod to the bottle calibration frame is greater than the horizontal distance from the circular pulley to the bottle calibration frame.

[0009] The length of the propping rod is the same as the length of the bottleneck slideway, and the length of the bottle correction frame is shorter than the length of the propping rod.

During the rotation, the front end of the bottle adjustment plate is designed with an arc surface, which reduces the collision between the large infusion bottle and the bottle adjustment plate, and reduces the external force on the large infusion bottle itself. At the same time, due to the friction between the protrusion under the bottle mouth and the bottleneck slide, the large infusion bottle will not be rotated at too large an angle, and the thickness of the bottle adjustment plate can be adjusted to achieve the goal of rotating the bottle body 90°. After the rotation of the bottle body is completed, the large infusion bottle continues to run along the bottleneck slide for a distance, and when the circular wheel axle is separated from the expansion rod, the movable finger is reset under the action of the reset spring, and the bottleneck of the large infusion bottle continues to be tightened, and it is brought into the bottle washing equipment through the handover finger.

[0011] The automatic steering device for large infusion bottles of the present invention has reasonable design, simple structure and convenient use. A bottle calibration bracket is arranged on a traditional bottle washing equipment, and the angle of the large infusion bottle is adjusted by the bottle calibration plate of the bottle calibration bracket to meet the needs of the bottle washing equipment. An opening device capable of automatically releasing and clamping the movable fingers is arranged on the junction fingers, so that the large infusion bottle can be automatically released from the bottle calibration bracket, which is convenient for adjusting its angle. After the bottle calibration is completed, the bottle can be automatically reset and re-clamped, which greatly improves the efficiency of calibration and realizes the automatic production of the equipment.
