Description

Technical Field

[0001] The utility model relates to the technical field of air volume measurement, in particular to a device for measuring the air volume at the top of a soft-packaged infusion plastic bottle. Background Art

[0002] When filling a soft-packaged infusion plastic bottle, a certain volume of gas generally needs to be left. The presence of the gas at the top of the bottle helps to reduce the deformation of the bottle body caused by factors such as air pressure difference and temperature change during transportation, thereby reducing losses, and avoiding the oxidation reaction of the liquid medicine during storage and transportation, and prolonging the shelf life of the liquid medicine.

[0003] In actual production, it is necessary to determine the air volume at the top of the soft-packaged infusion plastic bottle. Therefore, it is necessary to measure it. The existing method is to measure it by sucking with a syringe. However, during the operation process, the air is easily compressed, resulting in a smaller data and inaccurate test results.

By the combined use of a graduated cylinder, a manual lifting frame, a first-stage manual adjusting clamp and a second-stage manual adjusting clamp, the soft-packaged infusion plastic bottle is compressed, and the gas inside it is introduced into the graduated cylinder. Then, the liquid level in the graduated cylinder is adjusted by the manual lifting frame to be flush with the liquid level in the outer water tank. The read scale is the gas volume above the soft-packaged infusion plastic bottle, which greatly improves the accuracy of the gas volume and reduces the influence of gas volume compression on the accuracy of the test data.

[0005] The present utility model is implemented by adopting the following technical solutions:

[0006] The device for measuring the air volume at the top of the soft-packaged infusion plastic bottle includes a water tank. A graduated cylinder is arranged inside the water tank. The graduated cylinder is connected to the top of the soft-packaged infusion plastic bottle through a hose. A first-stage manual adjusting clamp and a second-stage manual adjusting clamp are arranged on both sides of the soft-packaged infusion plastic bottle. A tightening shaft is connected between the first-stage manual adjusting clamp and the second-stage manual adjusting clamp. The graduated cylinder is inverted in the water inside the water tank.

[0007] A base is arranged below the water tank, and an iron stand is arranged on the base.

[0008] The iron stand is connected to the graduated cylinder through a manual lifting frame.

[0009] A rubber gasket is arranged at the connection between the graduated cylinder and the hose, and a puncture needle is arranged on the hose.

[0010] When in use, the puncture needle pierces through the rubber gasket and is connected to the graduated cylinder.

[0011] The hose is provided with a puncture device on one side away from the puncture needle, and a hose clamp is provided on the hose.

[0012] The tightening shaft is provided with a locking nut and a locking pressure plate. The locking nut is located on the side close to the first clamping plate of the manual adjustment clamp, and the locking pressure plate is located on the side close to the second clamping plate of the manual adjustment clamp.

[0013] The tightening shaft is provided with threads and is used in cooperation with the locking nut. When the locking nut is rotated, the first clamping plate and the second clamping plate of the manual adjustment clamp on the tightening shaft will move, either moving towards the middle or moving towards both sides simultaneously.

[0014] The working principle of the present utility model is as follows:

[0015] Place the soft-packaged infusion plastic bottle between the first clamping plate and the second clamping plate of the manual adjustment clamp, and rotate the locking nut so that the first clamping plate and the second clamping plate of the manual adjustment clamp on both sides are in a slightly clamped state with the soft-packaged infusion plastic bottle, without moving up, down, left, or right; fill water in the water tank, insert the puncture needle into the rubber gasket, adjust the manual lifting frame to adjust the bottom of the two barrels to be flush with the liquid level, and exhaust the internal air; then insert the puncture device into the soft-packaged infusion plastic bottle, adjust and rotate the locking nut, and the first clamping plate and the second clamping plate of the manual adjustment clamp on the tightening shaft move towards the middle until the liquid medicine rises to the top of the soft-packaged infusion plastic bottle; then adjust the manual lifting frame until the liquid level inside the measuring cylinder is flush with the liquid level in the water tank, and then read the volume on the measuring cylinder. Among them, the tightening shaft is provided with threads and is used in cooperation with the locking nut. When the locking nut is rotated, the first clamping plate and the second clamping plate of the manual adjustment clamp on the tightening shaft will move, either moving towards the middle or moving towards both sides simultaneously.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] By using the measuring device for the air volume at the top of the soft-packaged infusion plastic bottle of the present utility model, through the coordinated use of the measuring cylinder, the manual lifting frame, the first clamping plate of the manual adjustment clamp, and the second clamping plate of the manual adjustment clamp, the soft-packaged infusion plastic bottle is compressed, and the internal gas is introduced into the measuring cylinder. Then, the liquid level in the measuring cylinder is adjusted through the manual lifting frame to be flush with the liquid level in the outer water tank, and the reading scale is the air volume above the soft-packaged infusion plastic bottle, greatly improving the accuracy of the gas volume and reducing the influence of gas volume compression on the accuracy of the test data.
