Description

Technical Field

[0001] This utility model relates to a weight detection device for a paper cup production line. Background Technology

[0002] In the paper cup production process, the weight of the finished paper cups needs to be checked to ensure the quality of the paper cups. In the existing technology, gravity sensors are generally used to detect the paper cups. Although this can achieve the purpose, the cost of the entire detection device is relatively high and the detection efficiency is not high, which affects the production efficiency.

The motor is drivenly connected to the middle of the rotating rod through the rotating shaft. The two measuring rings are respectively set at both ends of the rotating rod. One of the measuring rings is located in the gap between the upper and lower tubes. The inner ring of the measuring ring is provided with several spring pieces, which are evenly arranged circumferentially around the center of the measuring ring. The measuring ring located in the gap between the upper and lower tubes is coaxially arranged with the upper tube. The lower tube has a rectangular opening at the end near the upper tube.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figure 1-3 As shown, a weight detection device for a paper cup production line includes a feeding assembly and a measuring assembly;

[0018] The material guiding assembly includes an upper tube 1, a lower tube 2, and a connecting rod 3. The upper tube 1 and the lower tube 2 are coaxially arranged. The upper tube 1 is located directly above the lower tube 2. One end of the connecting rod 3 is connected to the upper tube 1, and the other end of the connecting rod 3 is connected to the lower tube 2. A gap is provided between the upper tube 1 and the lower tube 2.

[0019] The measuring assembly includes a measuring unit and a motor 4. The motor 4 is connected to the measuring unit and is fixed on one side of the lower tube 2. The measuring unit includes a rotating shaft 5, a rotating rod 6, and two measuring rings 7. The rotating rod 6 is perpendicular to the axis of the lower tube 2. The motor 4 is connected to the middle of the rotating rod 6 via the rotating shaft 5. The two measuring rings 7 are respectively set at both ends of the rotating rod 6. One of the measuring rings 7 is located in the gap between the upper tube 1 and the lower tube 2. The inner ring of the measuring ring 7 is provided with several spring pieces 11. Each spring piece 11 is evenly arranged circumferentially around the center of the measuring ring 7. The measuring ring 7 located in the gap between the upper tube 1 and the lower tube 2 is coaxially arranged with the upper tube 1. The lower tube 2 has a rectangular opening at the end near the upper tube 1.

[0020] Two laser sensors 10 are provided on the inner side of the lower tube 2 near the upper tube 1, and the two laser sensors 10 are positioned facing each other.

[0021] Preferably, a fixing ring 8 is provided at the center of the rotating rod 6, and the rotating shaft 5 passes through the fixing ring 8.

[0022] Preferably, the upper end of the rotating shaft 5 is provided with a bearing seat 9, the bearing seat 9 is fixed on one side of the upper tube 1, one end of the rotating shaft 5 is connected to the motor 4 for transmission, and the other end of the rotating shaft 5 is connected to the bearing seat 9.

[0023] During measurement, the upper end of the upper tube 1 of the paper cup falls into the tube, and the paper cup falls by itself. When it passes the measuring ring 7, the mouth of the paper cup will be blocked by the spring piece 11. If the weight of the paper cup is up to standard and the size of the mouth of the cup is not larger than the standard size, the paper cup will break through the restriction of the spring piece 11 and continue to fall. If the weight of the paper cup is not up to standard or the size of the mouth of the cup is larger than the standard size, the paper cup will be stuck by the spring piece 11 in the measuring ring 7. When the paper cup is stuck, the laser sensor 10 will detect that the paper cup is stuck, and the motor 4 will drive the rotating shaft 5 to rotate, thereby rotating the other measuring ring 7 by 180° to replace the measuring ring 7. In this way, the sensing work can continue, while defective products are transferred out of the tube.

[0024] The bearing housing 9 is set here mainly to ensure the stability and accuracy of the rotation of the two measuring rings 7.

[0025] Compared with existing technologies, this weight detection device for paper cup production lines can not only sense the weight of paper cups by their free fall, but also detect the diameter of the cup rim. Paper cups that have passed the inspection can pass through smoothly, while paper cups that do not meet the standards can be automatically rejected by motor 4, thereby ensuring the continuity of production and inspection.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
