Description

Technical Field

[0001] The utility model relates to the technical field of oral liquid filling, in particular to an adjustable liquid injection structure for oral liquid filling equipment. Background Art

[0002] Oral liquid is based on Chinese herbal decoction. The active ingredients in the medicine are extracted, and additives such as flavoring agents and antibacterial agents are added. It is made into a sterile or semi-sterile oral liquid preparation according to the ampoule filling process of injection. Therefore, it is also called oral ampoule. Oral liquid needs to be stored and filled after production.

[0003] At present, the injection structure of most oral liquid filling equipment operates on a single line, injecting liquid into an oral bottle liquid conveyor belt, which is inefficient. In addition, the injection structure of most oral liquid filling equipment is fixed, and the height of the injection needle cannot be adjusted. When filling different types of oral liquid bottles, the injection structure of the oral liquid filling equipment needs to be replaced, which is complicated. Utility Model Content

[0006] Preferably, both the top of the Y-shaped bracket and the top of the adjusting ring are provided with limiting holes, and the limiting columns are commonly inserted inside the two limiting holes. After the height adjustment is completed, the limiting hole provided at the top of the adjusting ring is rotated to below the limiting hole provided at the top of the Y-shaped bracket, and the limiting columns are inserted into the two limiting holes to fix the adjusting ring so that the screw rod can move without being affected by gravity.

[0007] Preferably, the top of the adjusting ring is sleeved inside the front end of the bracket, and the adjusting ring is threadedly connected to the screw. The adjusting ring is rotated to cause the screw to move linearly up and down to adjust the height of the injection needle. There is no need to replace the injection structure when filling oral liquid bottles of different models, and the application range is wide.

[0008] Preferably, the outer surface of the anti-rotation shell is sleeved with a locking bracket, and the bottom end of the locking bracket is fixedly mounted on the top surface of the bracket. When the adjusting ring is rotated, the screw is restricted by the locking bracket through the anti-rotation shell and will not rotate, thereby ensuring that the screw can be driven to perform linear up and down motion.

[0009] Preferably, two guide rails are provided at both side edges of the bottom end of the bracket, and sliders are sleeved on the outer surfaces of the two guide rails. The guide rails are limited by the sliders so that the bracket will not tilt when performing arc-shaped linear motion.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The adjustable liquid injection structure of the oral liquid filling equipment drives the end of the rotating rod to rotate through a motor, and the head end of the rotating rod pulls the crank, which drives the top of the connecting rod to swing back and forth, so that the bracket reciprocates along the arc groove as a trajectory. When the bracket reciprocates, the guide rail is limited by the slider and performs linear motion in the vertical direction, so that the bracket will not tilt when performing arc linear motion, and the injection needle is alternately raised and lowered above the two conveying mechanisms. When the injection needle descends, it is inserted into the oral liquid bottle for injection. After the injection is completed, the injection needle rises and moves to the other conveying mechanism, and then descends again for injection. The oral liquid bottles on the two conveying lines are injected, thereby improving the efficiency of the injection structure and the injection speed.

[0013] 2. The adjustable injection structure of the oral liquid filling equipment is used in conjunction with an adjusting ring and a screw. When the adjusting ring is rotated, the screw is restricted by the locking bracket through the anti-rotation housing and will not rotate, so the screw will be raised or lowered to adjust the height of the injection needle. There is no need to replace the injection structure when filling oral liquid bottles of different models, and the application range is wide. BRIEF DESCRIPTION OF THE DRAWINGS
