Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a bottom support structure based on weight automatic control. Background Technique

[0002] The reaction cup is the place where the sample and the reagent carry out chemical reactions and is also used as a colorimetric cup. The reaction cup plays a crucial role in chemical analysis and biochemical experiments. They are not only the place where chemical reactions occur, but also used as colorimetric cups, which is necessary in many analytical methods. The design and material of the reaction cup are crucial for ensuring the accuracy and reliability of the experiment. For example, hard materials with good light transmittance are often used to make reaction cups to ensure the accurate transmission of the light path and the smooth progress of the reaction.

[0003] During the packaging operation of the reaction cups, a large number of reaction cups will be collected in a sub-packaging box. When a certain amount is collected in one sub-packaging box, another sub-packaging box is automatically conveyed to the corresponding position. The existing reaction cup packaging operation adopts traditional manual packaging, which cannot achieve quantitative collection when collecting reaction cups in the sub-packaging box and cannot achieve continuous packaging operation. Adopting traditional manual packaging greatly increases the labor cost and results in low packaging work efficiency. For this reason, we propose a bottom support structure based on weight automatic control to achieve continuous packaging operation of reaction cups. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bottom support structure based on weight automatic control to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A bottom support structure based on weight automatic control, including a frame, an activity frame is arranged on the frame, and a plurality of rotating rollers for conveying the sub-packaging box are rotatably arranged on the activity frame. Elastic components fixed on the frame are respectively arranged at the four corners of the bottom of the activity frame, and the activity frame can move up and down on the frame through the elastic telescopic of the elastic components;

[0007] A worm gear is fixed at one end of the rotating roller, a rotating shaft is rotatably arranged on the frame, and a worm meshed with the worm gear is fixed on the rotating shaft;

[0008] A bearing frame for placing the sub-packaging box is fixed on the frame, and a pushing mechanism is arranged above the bearing frame, and the pushing mechanism is used to push the sub-packaging box on the bearing frame onto the rotating roller.

[0009] For a bottom support structure based on weight automatic control as described above: the rotating shaft is driven to rotate by a motor fixed on the frame, and the output end of the motor is connected with the rotating shaft through a coupling.

[0010] A bottom support structure based on weight automatic control as described above: The elastic component includes an outer cylinder fixed on the frame. An inner rod fixed to the bottom of the movable frame is movably inserted into the outer cylinder, and a spring is sleeved on the inner rod.

[0011] A bottom support structure based on weight automatic control as described above: The pushing mechanism includes a cylinder fixed on the frame. A push plate is fixed to the output end of the cylinder, and the bottom of the push plate is smooth and slidably connected to the upper surface of the bearing frame.

[0012] A bottom support structure based on weight automatic control as described above: The two sides of the movable frame are respectively fixed with railing plates.

[0013] A bottom support structure based on weight automatic control as described above: One end of the movable frame away from the bearing frame is fixed with an inclined plate.

[0014] A bottom support structure based on weight automatic control as described above: A travel switch fixed on the frame is installed at the bottom of the movable frame. The travel switch is electrically connected to the cylinder through a wire. The travel switch is used to receive the mechanical collision of the movable frame, and its contact acts to turn on or off the control circuit to control the start and stop of the cylinder.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: Elastic components fixed on the frame are respectively arranged at the four corners of the bottom of the movable frame. The elastic components elastically expand and contract to enable the movable frame to move up and down on the frame. Thus, after the reaction cups in the dispensing box placed on the movable frame collect a certain weight, the load borne by the movable frame will cause the elastic components to contract, thereby driving the movable frame to move downward, and then driving the worm gear to move downward to contact and mesh with the rotating worm, thereby driving the worm gear to roll and driving the rotating roller to rotate to output the dispensing box after collecting a certain weight of reaction cups to one side for packaging. At the same time, when the movable frame moves downward, it elastically collides with the travel switch, triggering the travel switch to drive the cylinder to start, and the push plate conveys another dispensing box onto the movable frame, facilitating continuous packaging of the reaction cups;

[0016] Furthermore, the present utility model can realize automatic outward transportation of a dispensing box after collecting a certain weight of reaction cups, and at the same time, another dispensing box is automatically transported to the corresponding position, thereby realizing quantitative collection when collecting reaction cups in the dispensing box and realizing continuous packaging operations, greatly reducing labor costs and effectively improving the efficiency of packaging work.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Please refer to Figures 1 to 5 , as an embodiment of the present invention, a bottom support structure based on weight self-control includes a frame 1. A movable frame 2 is arranged on the frame 1. A plurality of rotating rollers 3 for transporting the sub-packaging box 14 are rotatably arranged on the movable frame 2. Elastic components 8 fixed on the frame 1 are respectively arranged at the four corners of the bottom of the movable frame 2. The movable frame 2 can move up and down on the frame 1 through the elastic expansion and contraction of the elastic components 8;

[0025] One end of the rotating roller 3 is fixed with a worm gear 4. A rotating shaft 5 is rotatably arranged on the frame 1. A worm 6 meshed with the worm gear 4 is fixed on the rotating shaft 5;

[0026] A placing frame 9 for placing the sub-packaging box 14 is fixed on the frame 1. A pushing mechanism is arranged above the placing frame 9. The pushing mechanism is used to push the sub-packaging box 14 on the placing frame 9 onto the rotating roller 3.

[0027] In this embodiment, elastic components 8 fixed to the frame 1 are respectively provided at the four corners of the bottom of the movable frame 2. The elastic components 8 elastically expand and contract to enable the movable frame 2 to move up and down on the frame 1. Thus, after the reaction cups in the dispensing box 14 placed on the movable frame 2 collect a certain weight, the load borne by the movable frame 2 will cause the elastic components 8 to contract, driving the movable frame 2 to move downward. Then, the worm wheel 4 is driven to move downward and come into contact with and engage with the rotating worm 6, driving the worm wheel 4 to roll and driving the rotating roller 3 to rotate, so as to output and package the dispensing box after collecting a certain weight of reaction cups to one side. At the same time, when the movable frame 2 moves downward, another dispensing box 14 is conveyed onto the movable frame 2 through the pushing mechanism, facilitating continuous packaging of the reaction cups.

[0028] As a further solution of the present utility model, the rotating shaft 5 is driven to rotate by a motor 7 fixed on the frame 1, and the output end of the motor 7 is connected to the rotating shaft 5 through a coupling.

[0029] In this embodiment, starting the motor 7 can drive the rotating shaft 5 to rotate.

[0030] As a further solution of the present utility model, the elastic component 8 includes an outer cylinder body 801 fixed to the frame 1. An inner rod 802 fixed to the bottom of the movable frame 2 is movably inserted into the outer cylinder body 801, and a spring 803 is sleeved on the inner rod 802.

[0031] In this embodiment, when the movable frame 2 bears a load, it drives the inner rod 802 to be inserted into the outer cylinder body 801, and at the same time, it presses down the spring 803.

[0032] As a further solution of the present utility model, the pushing mechanism includes a cylinder 11 fixed to the frame 1. A push plate 10 is fixed to the output end of the cylinder 11, and the bottom of the push plate 10 is smooth and is slidably connected to the upper surface of the bearing frame 9.

[0033] In this embodiment, when the cylinder 11 is started, it pushes the push plate 10 to move, so as to push another dispensing box 14 onto the movable frame 2 through the push plate 10.

[0034] As a further solution of the present utility model, retaining plates 12 are respectively fixed to both sides of the movable frame 2.

[0035] In this embodiment, when the dispensing box 14 is conveyed on the movable frame 2, its two sides are limited to prevent the dispensing box 14 from falling off the movable frame 2.

[0036] As a further solution of the present utility model, an inclined plate 13 is fixed to one end of the movable frame 2 away from the bearing frame 9.

[0037] In this embodiment, it is convenient to guide and convey the dispensing box 14 outwards from the movable frame 2.

[0038] As a further solution of the utility model, a travel switch 15 fixed to the frame 1 is installed at the bottom of the movable frame 2. The travel switch 15 is electrically connected to the air cylinder 11 through a wire. The travel switch 15 is used to receive the mechanical collision of the movable frame 2, and its contact is actuated to realize the on-off control circuit to control the start and stop of the air cylinder 11.

[0039] In this embodiment, when the movable frame 2 moves downward, it elastically collides with the travel switch 15, causing the contact of the travel switch 15 to actuate, triggering the travel switch 15 to drive the air cylinder 11 to start, and conveying another sub-packaging box 14 to the movable frame 2 through the push plate 10.

[0040] It should be noted that when the movable frame 2 bears the load and moves down to the bottom, it is flush with the height of the placement frame 9, which is convenient for pushing the sub-packaging box 14 from the placement frame 9 onto the movable frame 2.

[0041] The working principle of the utility model is as follows: when collecting reaction cups, first place a sub-packaging box 14 on the movable frame 2 and place another sub-packaging box 14 on the placement frame 9. Thus, when the reaction cups in the sub-packaging box 14 placed on the movable frame 2 collect to a certain weight, the movable frame 2 bearing the load will cause the elastic component 8 to contract, thereby driving the movable frame 2 to move downward, and then driving the worm gear 4 to move downward to contact and mesh with the rotating worm 6, thereby driving the worm gear 4 to roll and driving the rotating roller 3 to rotate to output and package the sub-packaging box 14 after collecting a certain weight of reaction cups to one side. At the same time, when the movable frame 2 moves downward, it elastically collides with the travel switch 15, triggering the travel switch 15 to drive the air cylinder 11 to start, and conveying another sub-packaging box 14 to the movable frame 2 through the push plate 10. Another sub-packaging box 14 continues to collect reaction cups, which is convenient for continuously packaging the reaction cups.

[0042] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the utility model, all technical solutions that can implement the utility model in other specific forms are included in the utility model.
