Description

Technical Field

[0001] This utility model relates to the field of reagent filling technology, specifically to a positioning structure for a reagent weighing and filling machine. Background Technology

[0002] Chemical reagents are relative standard substances used in chemical research and component analysis. They are an important condition for scientific and technological progress and are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. After production and synthesis, chemical reagents need to be packaged to facilitate their transportation, sales and storage.

[0003] There is a reagent container that is rectangular in shape and includes three fixedly connected reagent bottles. The three reagent bottles are used to hold different reagents. In use, the three reagent bottles (first reagent bottle, second reagent bottle and third reagent bottle) are placed on three different weighing and filling machines in sequence, and the first reagent bottle, second reagent bottle and third reagent bottle are filled by the three weighing and filling machines respectively.

[0004] However, the existing weighing and filling machines still have some shortcomings: when placing the three reagent bottles as a whole onto different weighing and filling machines, manual positioning is required to ensure that the three reagent bottles are positioned directly below the filling head in sequence, which can easily lead to inaccurate positioning and low filling efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a positioning structure for a reagent weighing and filling machine that addresses the above-mentioned deficiencies. When reagent bottles are placed on different weighing and filling machines for filling, the structure can automatically position the reagent bottles with high accuracy and improve work efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a positioning structure for a reagent weighing and filling machine, including a base and a first positioning plate and a second positioning plate that are adjustable on both sides of the base. The first positioning plate is provided with a limiting part that can position it to three positions. When the first positioning plate moves to these three positions respectively, the three reagent bottles can be located directly below the filling head. Along the length direction of the base, a tension spring is provided between the second positioning plate and the base.

[0007] The working principle of this solution is as follows: Three weighing and filling machines with positioning structures are placed sequentially at intervals. The first positioning plate on the first weighing and filling machine is located at the first limit position, the first positioning plate on the second weighing and filling machine is located at the second limit position, and the first positioning plate on the third weighing and filling machine is located at the third limit position. When the first reagent needs to be filled into the first reagent bottle, the second positioning plate is pulled away from the first positioning plate. Then, the three reagent bottles are placed on the upper side of the base, so that one side of the third reagent bottle abuts against the inner side of the first positioning plate. Then, the hand is released, and the second positioning plate moves under the action of the tension spring to abut against one side of the first reagent bottle, thereby fixing the three reagent bottles and positioning the first reagent bottle directly below the filling head.

[0008] After the first reagent is filled into the first reagent bottle, it is removed from the first weighing and filling machine and placed on the base of the second weighing and filling machine. The above steps are repeated to fix the three reagent bottles with the first and second positioning plates and to position the second reagent bottle directly below the filling head. The second reagent is then filled into the second reagent bottle. Then the above steps are repeated to position the third reagent bottle directly below the filling head on the third weighing and filling machine, thereby filling the third reagent into the third reagent bottle.

[0009] Compared with the existing technology, the beneficial effects of this solution are as follows: by adjusting the position of the first positioning plate on the three weighing and filling machines and the cooperation between the first positioning plate and the second positioning plate, when the reagent bottle is placed on each weighing and filling machine as a whole, it can be positioned by the first positioning plate and the second positioning plate, so that the first reagent bottle, the second reagent bottle and the third reagent bottle are respectively located directly below the filling head. This avoids the problem of inaccurate positioning and low efficiency that may occur when the reagent bottle is placed on different weighing and filling machines, which requires manual alignment of the reagent bottle mouth with the filling head.

[0010] In a preferred embodiment of the present invention, the base is provided with symmetrical sliding grooves on both sides. The first positioning plate includes a first vertical plate and a first horizontal plate arranged perpendicularly to each other. The second positioning plate includes a second vertical plate and a second horizontal plate arranged perpendicularly to each other. The first horizontal plate and the second horizontal plate are slidably engaged with the two sliding grooves respectively. The tension spring is located between the second horizontal plate and the side wall of the sliding groove.

[0011] The beneficial effects of this solution are as follows: by having the first horizontal plate and the second horizontal plate slide in conjunction with the two sliding grooves respectively, the first positioning plate and the second positioning plate slide in conjunction with the two sides of the base respectively, thereby adjusting the distance between the first vertical plate and the second vertical plate to accommodate different reagent bottles located directly below the filling head.

[0012] In a preferred embodiment of this utility model, three slots are symmetrically arranged on the sidewalls of the sliding groove that slides with the first horizontal plate. The first horizontal plate has a receiving groove along its length and through grooves that communicate with the two receiving grooves symmetrically arranged along its width. The limiting part includes a limiting block disposed in the receiving groove and a locking block disposed on one side of the limiting block and extending out of the through groove. The locking block can engage with the slot. Compression springs are connected between the side of the two limiting blocks that are close to each other and the sidewall of the receiving groove.

[0013] The beneficial effects of this solution are as follows: When it is necessary to adjust the position of the first positioning plate on the base, press the two limiting blocks in the direction of mutual approach to make the locking blocks disengage from the slots. Then slide the first horizontal plate along the slide groove and release it when it is in the appropriate position. The two limiting blocks move in the direction of mutual distance under the action of the compression spring, so that the locking blocks are locked into the slots at different positions. The first positioning plate set on different weighing and filling machines is moved to different limiting positions, so that the three reagent bottles can be positioned separately.

[0014] In a preferred embodiment of this utility model, clamping blocks are respectively provided on the side of the first vertical plate and the second vertical plate that are close to each other. The front end of the clamping block has a first groove, and the length of the first groove matches the width of the reagent bottle.

[0015] The beneficial effects of this solution are as follows: the first reagent bottle and the third reagent bottle are clamped by two clamping blocks respectively. Since the length of the first groove matches the width of the reagent bottle, the first reagent bottle and the third reagent bottle can be inserted into the first groove, thereby limiting the width of the reagent bottle as a whole and ensuring a more stable filling process.

[0016] In a preferred embodiment of the present invention, the upper part of the base has two second grooves on both sides along the vertical direction, which are connected to the two sliding grooves. The length of the second groove matches the length of the first vertical plate and the second vertical plate.

[0017] The beneficial effects of this solution are as follows: If a second groove communicating with the slide is not provided on the upper side of the base, when the first reagent bottle is located directly below the filling head, the distance between the first reagent bottle and the second positioning plate is large, and the second positioning plate can only move to its inner side to contact one side of the base, and cannot contact and position the first reagent bottle.
