Description

Technical Field

[0001] The utility model relates to the technical field of glass bottle detection equipment, in particular to a batch detection device for the mouths of oral liquid glass bottles. Background Art

[0002] In traditional packaging production lines, the inspection of glass bottles often focuses on the final inspection of finished products, especially the leakage detection of the bottle mouth after packaging. Although this method can screen out unqualified products to a certain extent, it has obvious limitations and defects. Specifically:

[0003] 1. Delayed detection: Existing leak detection is usually carried out after the product is packaged, which means that problems with the bottle mouth can only be discovered after packaging is completed. This post-detection method cannot correct quality problems in the production process in a timely manner, resulting in unnecessary material waste.

[0004] 2. Serious material loss: Leakage caused by defects in the bottle mouth or poor sealing will be discovered during post-packaging inspection, and the entire batch of affected products will be treated as waste, which not only directly causes the loss of raw materials and semi-finished products, but also adds additional processing costs and environmental burdens.

[0005] 3. Low production efficiency: Post-leak detection is often accompanied by complex detection processes and a high false detection rate, which not only consumes a lot of time and human resources, but also may seriously affect the operating efficiency and overall output of the production line due to frequent shutdown inspections and rework.

[0006] 4. Product quality risk: Failure to effectively inspect the bottle mouth at an early stage may result in some minor defects that are sufficient to affect the long-term sealing performance being overlooked, thereby affecting the shelf life of the product and the safety and health of consumers. Summary of the invention

[0007] The technical problem to be solved by the utility model is the lack of early detection of glass bottles.

[0009] Preferably, the detection unit also includes a test seat and the docking joints arranged side by side on the test seat, the airflow duct includes a connecting tube and an air supply tube fixedly arranged on the test seat, a plurality of the docking joints are connected in parallel on the connecting tube, a plurality of the connecting tubes are connected in parallel on the air supply tube, and the sealing test unit is connected to the top of the docking joints.

[0010] Preferably, the sealing test unit comprises a transparent tube connected to the top of the docking joint and a plastic ball vertically slidably arranged in the transparent tube, and the outer wall of the plastic ball fits with the inner wall of the transparent tube.

[0011] Preferably, a connecting rod is fixedly provided at the bottom of the test seat, an annular support plate is fixed at the bottom end of the connecting rod, the docking joint is vertically slidably provided between the test seat and the support plate, and a spring is mounted on the docking joint, the top end of the spring is fixedly connected to the docking joint, the bottom end of the spring is fixedly connected to the top surface of the support plate, and under the action of the spring, there is a gap between the top end of the docking joint and the test seat.

[0013] Preferably, the supporting plate is provided with matching holes matched with the bottom ends of the glass bottles in an array.

[0014] The utility model provides a device for batch inspection of the mouths of oral liquid glass bottles. A load-bearing plate is provided to place glass bottles side by side in batches. The load-bearing plate is pushed by a cylinder so that the mouths of the glass bottles are docked with a docking joint. Before docking, negative pressure is generated by an air flow duct to draw a plastic ball to the top of a transparent tube. After docking, reverse inflation is performed slowly to observe the descending position of the plastic ball. If the plastic ball is located at the bottom of the transparent tube, the seal with the docking joint fails, thereby realizing early batch inspection of the glass bottles.

DETAILED DESCRIPTION

[0021] like Figure 1-4 A device for batch testing of the mouth of glass bottles of oral liquid comprises a base 1, a supporting plate 2 vertically lifted and arranged on the base 1 to accommodate glass bottles 5, and a testing unit fixed directly above the supporting plate 2. The testing unit comprises an airflow pipeline, a butt joint 14 connected to the airflow pipeline, and a sealing test unit arranged on the airflow pipeline. The butt joint 14 is located directly above the top port of the glass bottle 5, and the outer diameter of the butt joint 14 is smaller than the outer diameter of the port of the glass bottle 5, and larger than the inner diameter of the port of the glass bottle 5.

[0022] The base 1 is fixedly arranged, and a groove is arranged on the top of the base 1, and the groove is adapted to the bearing plate 2 to ensure the vertical sliding of the bearing plate 2; a guide column 3 is fixed at the bottom of the bearing plate 2, and the guide column 3 vertically penetrates the base 1 to guide the sliding of the bearing plate 2. A push cylinder 4 is installed at the bottom of the base 1, and the output end of the push cylinder 4 penetrates the base 1 and is fixedly connected to the bearing plate 2, and the bearing plate 2 is pushed upward by extending the movable end of the push cylinder 4.

[0023] The airflow pipeline is connected to an external air source device to realize the positive pressure and double pressure conversion in the airflow pipeline.

[0024] like Figure 1 and Figure 3 The detection unit also includes a test seat 6 and the docking joints 14 arranged side by side on the test seat 6, the airflow duct includes a connecting tube 7 and an air supply tube 8 fixedly arranged on the test seat 6, a plurality of the docking joints 14 are connected in parallel to the connecting tube 7, a plurality of the connecting tubes 7 are connected in parallel to the air supply tube 8, and the sealing test unit is connected to the top of the docking joint 14.

[0025] The gas supply cylinder 8 and the connecting cylinder 7 are both fixedly arranged, and the gas source equipment is connected to the gas supply cylinder 8 , and the gas source equipment supplies gas to all the docking joints 14 at the same time.

[0026] like Figure 1 and Figure 4 The sealing test unit comprises a transparent tube 9 connected to the top of the butt joint 14 and a plastic ball 10 vertically slidably arranged in the transparent tube 9 , and the outer wall of the plastic ball 10 is in contact with the inner wall of the transparent tube 9 .

[0027] When conducting the test, the air supply cylinder 8 and the connecting cylinder 7 are first controlled to be in a negative pressure state through the air source equipment, and the plastic ball 10 is adsorbed to the inner top of the transparent tube 9. After the docking joint 14 is docked with the top port of the glass bottle 5, the air source equipment is controlled to supply air to the air supply cylinder 8, so that the air pressure above the transparent tube 9 slowly increases. Since the air pressure inside the glass bottle 5 is atmospheric pressure, when the air pressure in the air supply cylinder 8 is increased, the pressurization rate is controlled according to the position of the plastic ball 10 in the transparent tube 9. When the plastic ball 10 is in the middle of the transparent tube 9, the pressurization is stopped and the positions of all the plastic balls 10 are observed. The plastic ball 10 located at the bottom of the transparent tube 9 corresponds to the failure of the seal between the glass bottle 5 and the docking joint 14.

[0028] A push light is also arranged on the test seat 6, and the push light corresponds to the docking joint 14 one by one. When the staff finds that the docking joint 14 and the glass bottle 5 have failed sealing, they press the push light and the light comes on, which is convenient for taking out the glass bottle 5 for the next step of testing.

[0029] like Figure 1 and Figure 4 As shown, in order to improve the tightness of the docking joint 14 and the glass bottle 5 and improve the accuracy of the detection. A connecting rod 12 is fixedly arranged at the bottom of the test seat 6, and an annular support plate 13 is fixed at the bottom end of the connecting rod 12. The docking joint 14 is vertically slidably arranged between the test seat 6 and the support plate 13, and a spring is sleeved on the docking joint 14. The top end of the spring is fixedly connected to the docking joint 14, and the bottom end of the spring is fixedly connected to the top surface of the support plate 13. Under the action of the spring, there is a gap between the top end of the docking joint 14 and the test seat 6.

[0030] After pushing the glass bottle 5 upward, the mouth of the glass bottle 5 contacts the bottom end of the docking head 14, and the mouth of the glass bottle 5 pushes the docking head 14 upward. When the docking head 14 moves upward, it pulls the spring, and the spring is in a stretched state. The docking head 14 is subjected to the downward elastic force of the spring, so that the docking head 14 is in close contact with the mouth of the glass bottle 5.

[0031] like Figure 4 As shown, in order to improve the accuracy of the movement of the docking joint 14, a guide rod 15 is vertically fixed on the side wall of the docking joint 14, and the guide rod 15 vertically penetrates the support plate 13. The guide rod 15 is used to guide the movement of the docking joint 14, and a protrusion is provided at the bottom end of the guide rod 15, which is used as a limit block to prevent the guide rod 15 from falling off the support plate 13.

[0032] like Figure 2 As shown, in order to achieve stable placement of the glass bottle 5, the supporting plate 2 is provided with matching holes 11 matched with the bottom ends of the glass bottles 5 in an array.
