[0002] Cosmetics refer to chemical industrial products or fine chemical products that are applied to any part of the human body surface, such as skin, hair, nails, lips and teeth, by smearing, spraying or other similar methods, for the purpose of cleaning, maintenance, beautification, modification and change of appearance, or correction of human body odor and maintenance of good condition.

[0003] There are many steps in the production of cosmetics, and the filling of liquid cosmetics is an indispensable step. After the filling is completed in the bottle, the quality of the product in the bottle needs to be tested to ensure that the quality of the product filled in the bottle meets the quality requirements.

[0004] However, currently, after bottle filling and other operations are completed, the products are generally collected and a few samples are selected from a batch of products for testing to determine whether the batch of products meets the requirements. However, the accuracy of this test is low. Alternatively, staff can set up electronic scales next to the conveyor belt to screen the moving products one by one. However, this method is affected by the speed of manual operation, has low efficiency, and consumes a lot of manpower. Utility Model Content

[0005] The purpose of the present invention is to provide a device for screening the weight of cosmetics after filling during transportation in order to overcome the defects of the prior art in that manual quality inspection is inefficient, time-consuming and labor-intensive.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0031] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0032] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown, this embodiment provides a device for screening cosmetic weight after filling during transportation, including a mounting frame 1, a conveyor belt 2, a driving member 3, a push plate 4, a receiving box 5 and a weight sensor. The upper end of the mounting frame 1 is provided with a mounting step 11;

[0035] The conveyor belt 2 is fixed on the mounting step 11. The driving member 3 is fixed on one side of the mounting step 11 and drives the push plate 4. The driving member 3 is a telescopic structure. The push plate 4 is located on the conveyor belt 2 and is perpendicular to the conveyor belt 2. The receiving box 5 is fixed on the side of the mounting step 11 opposite to the fixed driving member 3.

[0036] The weight sensor is fixed on the mounting frame 1 and is located between the conveyor belt 2 and the mounting frame 1. The output end of the weight sensor is connected to the comparison circuit and the switch circuit in sequence. The switch circuit is connected to the driving member 3, and the driving member 3 is connected to the power supply through the switch circuit.

[0037] Working principle: The product conveyor belt is set to an intermittent structure, and the conveyor belt 2 of the screening device is inserted into the product conveyor belt. When the filled product passes through the conveyor belt 11, the weight of the product is detected by the weight sensor; if the quality of the product meets the requirements, the switch circuit remains disconnected, the drive component 3 is powered off, and the product enters the next stage; if the quality of the product does not meet the requirements, the switch circuit is closed, the drive component 3 is powered, and the push plate 4 moves to one side of the receiving box 5, and pushes the unqualified products on the conveyor belt 2 into the receiving box 5, completing the screening of the products in transmission.

[0038] The weight sensor weighs the products being transported. If the product quality is acceptable, the switch circuit remains open and the push plate does not move. If the product is unqualified, the switch circuit closes, and the driver drives the push plate to push the unqualified product into the storage box, completing the screening of unqualified products. This screening device has a simple structure and can be directly added to the product production line for immediate use. It is flexible and easy to adjust and place, with a wide range of applications and strong practicality. By screening the products in transit, unqualified products are directly removed without affecting the normal delivery of qualified products, ensuring the production rhythm and production efficiency of the products. Compared with existing manual screening, it is more efficient and saves time and effort.

[0039] Among them, the weight sensor detects the quality of the product. If the detection result is greater than or equal to the threshold, the comparison circuit outputs a low level and the switch circuit remains open. If the detection result is less than the threshold, the comparison circuit outputs a high level and the switch circuit is closed.

[0040] The comparison circuit can be composed of a comparator and a feedback circuit, wherein the comparator is used to compare the size of the input signal, that is, to compare the detection signal with the preset threshold, and the feedback circuit is used to feed back the comparison result to the comparator, thereby controlling the output of the comparator. The two output results of the comparator control the opening and closing of the switching circuit, wherein the switching circuit can be implemented by semiconductor devices, such as transistors, relays, etc. These devices control the current on and off of the emergency module according to the output of the comparator.

[0041] In a preferred embodiment, the driving member 3 is a telescopic cylinder, a support frame is provided between the telescopic cylinder and the mounting frame 1, the support frame is fixed to one side of the mounting step 11, the telescopic cylinder is fixed on the support frame, and the telescopic rod of the telescopic cylinder is connected to the push plate.

[0042] Furthermore, the support frame includes a horizontal rod 12 and a vertical rod 13, the lower end of the vertical rod 13 is fixed to the mounting frame 1, the horizontal rod 12 is vertically fixed to the upper end of the vertical rod 13, and one end of the horizontal rod 12 is fixed to one side of the mounting step 11;

[0043] The lower end of the telescopic cylinder is provided with a U-shaped moving plate, which is provided with a long hole. The telescopic cylinder is fixed on the U-shaped moving plate, which is connected to the horizontal rod 12 by bolts and is clamped on the horizontal rod 12.

[0044] The push plate is driven to move horizontally by the telescopic cylinder, which can quickly move the push plate after detecting that the product quality is unqualified, and respond more quickly to avoid affecting the transportation of subsequent products; and the telescopic cylinder is fixed to the horizontal rod of the support frame through the U-shaped moving plate. The long holes and bolts set on the U-shaped moving plate can adjust the distance between the telescopic cylinder and the conveyor belt, that is, the initial distance between the push plate and the product, to adapt to the inspection of products of different shapes, with more flexible use and a wider range of applications.

[0045] The push plate 4 is provided with a protective layer 41 on the side away from the driving member 3. The protective layer 41 is an elastic structure. Optionally, the protective layer 41 is fixed to the push plate 4 by screws, and the material of the protective layer 41 is rubber.

[0046] By providing an elastic protective layer on the side of the push plate 4 that contacts the product, the push plate can protect the product when in contact with the product, without affecting the subsequent reuse of unqualified products, thus saving costs.

[0047] Specifically, the container 5 is a box body with openings at both ends. A triangular opening is provided on the side of the container 5 close to the conveyor belt 2, and an opening is provided on the upper side of the container 5. A protective layer is provided at the lower end of the interior of the container 5. The protective layer is a sponge pad.

[0048] The inclined opening facilitates the pushing of unqualified products into the storage box. An opening is provided above the storage box to facilitate subsequent observation of the interior of the bottle, thereby preventing the storage box from being full and affecting subsequent product screening, thereby ensuring the continuity of screening of the transmitted products. The protective layer placed at the bottom can also protect the products from rolling down.

[0049] Optionally, the end of the accommodating box 5 away from the conveyor belt 2 is tilted downward. In this way, the products entering the accommodating box 5 can be transferred to the side away from the conveyor belt 2 in time to avoid collision with subsequent products, thereby playing a role in assisting the protection of the products.

[0050] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
