AI Technical Summary
In the existing technology, the internal pressure detection of polypropylene infusion bottles and bags relies on subjective human judgment, which leads to inconsistent testing standards and results in products with insufficient internal pressure entering the market.
Design a device for detecting the internal pressure of polypropylene infusion bottles and bags, including a bracket and a scale. The device measures the internal pressure by using a support rod, a weight plate, and an optical axis limiting frame structure, combined with the weight change of the weight plate, to simulate the internal pressure of the product and provide a quantitative evaluation standard.
This technology enables standardized and quantitative testing of the internal pressure of polypropylene infusion bottles and bags, avoiding subjective errors, promptly identifying products with insufficient internal pressure, and ensuring product quality.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of large infusion production quality control, and particularly relates to a polypropylene infusion bottle and infusion bag internal pressure detection device. BACKGROUND
[0002] At present, when polypropylene infusion bottles and infusion bags are produced, the detection of whether the internal pressure of the product is full mainly relies on subjective judgment of people, there are differences in the judgment standards between different detection personnel, the product with insufficient internal pressure is not detected, and thus unqualified products flow into the market. INVENTION CONTENTS
[0003] In order to be able to quantitatively detect the internal pressure of the polypropylene infusion bottle and infusion bag product produced on site, avoid the influence of subjective evaluation of people on the judgment of the internal pressure of the product, the utility model provides a polypropylene infusion bottle and infusion bag internal pressure detection device for quantifying the internal pressure evaluation standard of the polypropylene infusion bottle and infusion bag product.
[0004] A polypropylene infusion bottle and infusion bag internal pressure detection device, characterized in that: it comprises a support and a scale, the support comprises a bottom plate, a bearing plate, a weight plate, a top plate, a support rod and an optical axis, the bottom plate, the bearing plate, the weight plate and the top plate are all isosceles trapezoids with the same area, the support rod is sequentially threaded through the three corners of the bottom plate, the bearing plate, the weight plate and the top plate, and is fixed at the connection of the bottom plate, the bearing plate and the top plate with the support rod using a bolt fixing piece, is connected at the connection of the support rod and the weight plate using a linear bearing, a through hole is formed on the top plate, the weight plate and the bearing plate, and a counterbore is arranged at the position corresponding to the through hole of the bottom plate, the optical axis is sequentially threaded through the through hole and fixed in the counterbore to form a limiting frame, the scale is sequentially threaded through the top plate, the weight plate and the bearing plate and fixed on the bottom plate, and the 0 scale line of the scale is flush with the top surface of the bearing plate.
[0005] Further, the limiting frame is provided with three optical axes distributed in a triangular shape at the front end, the spacing is matched with the size of the bottle opening and the bottle neck of the infusion bottle, at least one optical axis is arranged on each side, the optical axes on the two sides can use different specifications of the width of the infusion bottle according to the through hole inserted into different positions, and one optical axis is arranged at the rear side and corresponds to the position of the bottom of the infusion bottle.
[0006] The utility model discloses beneficial effect lies in: through the mounting position of different specification infusion bottle or infusion bag corresponding provided by the limiting frame, the product is placed on the bearing plate in turn and is stacked, and the weight plate is touched with the infusion bottle of the most top, measures an original height through the initial position of weight plate, places the weight of fixed weight on the weight plate, and the weight plate is moved down under the weight, and then measures a height after pressurization, judges whether the internal pressure of polypropylene infusion bottle and infusion bag meets the requirement through the way of exhausting to simulate the internal pressure of product, so that the internal pressure of polypropylene infusion bottle and infusion bag meets the requirement. The device structure is simple, convenient for daily operation, can judge in time whether the internal pressure meets, when the product of production site does not meet the internal pressure standard of polypropylene infusion bottle and infusion bag, can find in time and carry out corresponding adjustment to the batch product being filled, avoid the product of polypropylene infusion bottle and infusion bag internal pressure deficiency to flow into the market. BRIEF DESCRIPTION OF DRAWINGS
[0007] Figure 1 It is a kind of polypropylene infusion bottle and infusion bag internal pressure detection device.
[0008] Wherein: 1-bottom plate, 2-bearing plate, 3-weight plate, 4-top plate, 5-supporting rod, 6-bolt fixing piece, 7-linear bearing, 8-optical axis, 9-ruler, 10-infusion bottle. DETAILED DESCRIPTION
[0009] Example 1: a kind of polypropylene infusion bottle and infusion bag internal pressure detection device, it is characterized by: including support and ruler 9, support includes bottom plate 1, bearing plate 2, weight plate 3, top plate 4, supporting rod 5 and optical axis 8, bottom plate 1, bearing plate 2, weight plate 3 and top plate 4 are all same area isosceles trapezoidal, supporting rod 5 is sequentially passed through bottom plate 1, bearing plate 2, weight plate 3 and top plate 4 three corner places, and uses bolt fixing piece 6 to be fixed at the connection of bottom plate 1, bearing plate 2 and top plate 4 with supporting rod 5, uses linear bearing 7 to connect at the connection of supporting 5 rod and weight plate 3, top plate 4, bearing plate 2 and weight plate 3 are set up through hole, and bottom plate 1 is set up counterbore at the position of through hole, optical axis 8 is sequentially passed through through hole and fixed in counterbore and forms limiting frame, the front end of limiting frame is equipped with three optical axes 8 and is distributed in triangle, interval matches the size of infusion bottle mouth and bottle neck, the three optical axes 8 of front end are used to fix the mouth of infusion bottle 10, each side is equipped with one optical axis 8, and the optical axis 8 of both sides can use different specification infusion bottle 10 width according to inserting different positions through hole, rear side is equipped with one optical axis 8, and the position corresponds with the bottom position of infusion bottle 10, for limiting the bottom of infusion bottle. Ruler 9 is sequentially passed through top plate 4, bearing plate 2 and weight plate 3 and is fixed on bottom plate 1, and the 0 scale line of ruler 9 is flush with the top surface of bearing plate 2.
[0010] In use, the infusion bottle 10 is placed horizontally on a supporting plate, the infusion bottle 10 is limited by the optical axes 8, the bottom surface of the weight plate 3 is adjusted to contact the uppermost infusion bottle 10, then 3.5 g of weight is placed on the weight plate 3, the measurement value is obtained by observing the reading, and the value is not less than 36.5 cm, which indicates that the internal pressure meets the requirements, and 37 cm is the best.
