Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sampler technology, and more specifically, relates to a quantitative sampler. Background Technology
[0002] In many fields of scientific research, production and quality inspection, accurate quantitative sampling of various materials is a fundamental and crucial operation. Sheet materials such as paper, leather, textile fabrics and plastic films often require the acquisition of circular samples with precise area and weight for subsequent physical performance testing, chemical composition analysis, product standard comparison and other work. Circular quantitative samplers have emerged to meet this need.
[0003] Based on existing technology, it has been found that existing quantitative samplers have some shortcomings:
[0004] Firstly, in actual operation, the cutting tool is usually rigidly fixed to the movable rod of the sampler by means of bolts. However, in actual application scenarios, cutting samples with different characteristics often requires the adaptation of different types of cutting tools. As a result, whenever there is a need to change the cutting tool, the operator has to spend a lot of time and energy to disassemble and install the bolts. The operation process is extremely cumbersome and greatly affects work efficiency.
[0005] Secondly, the quantitative sampler lacks a structure to assist in fixing the sample. This defect causes the sample to easily wrinkle at the cut and in the surrounding area due to the downward squeezing force from the cutter when the cutter is performing the cutting task. These wrinkles not only destroy the original flatness of the sample, but more importantly, they will seriously interfere with various tests and analyses carried out on the sample, greatly reducing the usability of the sample. Utility Model Content
[0006] To address the aforementioned technical problems, this utility model relates to a quantitative sampler, which solves the problem of imperfect blade fixing structure in existing quantitative samplers. In actual use, the blade is usually fixed to the movable rod of the sampler by bolts. Since different blades need to be replaced for different samples, it is very troublesome to replace the blades. Moreover, due to the lack of a structure to fix the sample in the quantitative sampler, the sample is easily wrinkled at the cut due to the downward squeezing force when the cutter is cutting, thus affecting the use of the sample.
[0007] In a first aspect, this disclosure provides a quantitative sampler, achieved by the following specific technical means:
[0008] A quantitative sampler, including:
[0009] The installation mechanism includes a base, a mating component, and a guide plate. The base is rectangular with a circular groove at its upper end. The mating component is located outside the circular groove at the upper end. The guide plate is located below the circular groove at the upper end of the base. The installation mechanism has a main body, with a fixed frame on the upper end of the base. The pressure ring at the lower end of the fixed frame is adjacent to the mating component, and the pressure ring and the mating component are on the same axis. The main body has a lifting mechanism. The lifting rod of the lifting mechanism is slidably installed inside the fixed frame through an elastic element. The lifting rod can only move up and down within the fixed frame, and the teeth on the outer side of the lifting rod mesh with the gears inside the fixed frame. The lifting rod passes through the fixed frame and the pressure ring. The lifting rod and the mating component are on the same axis, and the cutter at the outer end of the lifting rod is inside the pressure ring.
[0010] According to some solutions of this utility model, the main structure includes: a fixed frame and a movable slot; the fixed frame has a hollow structure inside; the movable slot is opened at the lower front side of the fixed frame.
[0011] According to some solutions of this utility model, the main structure includes: a movable block and a pressure ring; the movable block is slidably installed in the movable groove through an elastic element, and a rectangular groove is opened on the front side of the movable block; the pressure ring is located at the front end of the movable block, and the rectangular block on the outside of the pressure ring is inserted into the rectangular groove in the movable block.
[0012] According to some solutions of this utility model, the main mechanism includes: a control lever and a gear; the control lever is rotatably mounted on the side end of the fixed frame; the gear is sleeved and fixed on the control lever, and the gear is located inside the fixed frame.
[0013] According to some solutions of this utility model, the main structure includes: side blocks and a protective cover; the side blocks are symmetrically arranged on both sides of the fixing frame; the protective cover is located at the lower front end of the fixing frame, and the rectangular blocks on both sides of the upper end of the protective cover are inserted and matched with the side blocks.
[0014] According to some solutions of this utility model, the main structure includes: a cover and an insert plate; the cover is located on the upper outer side of the fixing frame; the insert plate is inserted into the front inner end of the fixing frame.
[0015] According to some solutions of this utility model, the lifting mechanism includes: a lifting rod and a fixing pin; the lifting rod has teeth on its rear side and a circular groove at its bottom; the fixing pin is inserted into the lower front end of the lifting rod and can be magnetically connected to the lifting rod.
[0016] According to some embodiments of this utility model, the lifting mechanism includes: a cutter and a connecting rod; the cutter is located at the bottom of the lifting rod; the connecting rod is located at the top of the cutter, and the connecting rod is penetrated by a fixing pin.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. This device is equipped with a lifting mechanism. A circular groove is provided at the lower end of the lifting rod. The cutter is placed at the lower end of the lifting rod, and the connecting rod on the cutter is inserted into the circular groove at the bottom of the lifting rod. The fixing rod on the lifting rod passes through the connecting rod, so that the cutter is fixed on the lifting rod. When it is necessary to replace the cutter on the quantitative sampler, the insert plate is removed from the front side of the fixing frame, and then the fixing pin is pulled out from the lifting rod, thus removing its restraining effect on the connecting rod. At this time, the cutter can be smoothly pulled out from the lower end of the lifting rod for replacement. Compared with the traditional method, it significantly saves the time cost required for cutter replacement and provides a strong guarantee for efficient and continuous operation.
[0019] 2. In this device, a main body mechanism is set up. A movable block is slidably installed in the movable groove of the main body through an elastic element. A pressure plate is inserted into the front side of the movable block, so that the pressure ring and the lifting rod slide together, and the cutter is located at the inner end of the pressure ring. When the cutter descends and cuts, the elastic element pushes the pressure ring to move downward with the cutter through the movable block. With this first-mover advantage, the pressure ring contacts the sample first and firmly fixes the sample with just the right pressure. In this way, even if the cutter continues to press down, the sample will not wrinkle or deform due to the pressure, effectively ensuring the flatness and integrity of the sample after cutting, and comprehensively and effectively improving the quality level of the sample after sampling.
