Technical Field

[0001] This utility model relates to the field of weighing equipment, specifically a modified polypropylene automatic weighing device. Background Technology

[0002] Modified polypropylene is a synthetic material whose properties are improved by adding organic or inorganic modifiers to base polypropylene through physical or chemical methods. Currently, existing pellet weighing devices are typically located at the top of the tank, and are mostly passive weighing structures. These devices cannot directly weigh pellets from lower containers, resulting in cumbersome weighing procedures and reduced overall efficiency. Therefore, this paper proposes an automatic weighing device for modified polypropylene to address these issues. Utility Model Content

[0019] Please see Figure 1-3As shown, an automatic weighing device for modified polypropylene includes a weighing hopper 1, a side cover 2, an electro-hydraulic actuator 4, a motor 7, a weighing module 9, and a ring plate 10. The back of three triangular plates 8 located around the top port of the weighing hopper 1 are all connected to the weighing module 9, and the bottom of the weighing module 9 is fixedly connected to the surface of the ring plate 10. A spiral blade 3 is provided inside the short pipe 110 connected to the bottom of the weighing hopper 1, and the top of the spiral blade 3 is connected to the shaft end of the motor 7. The side cover 2 covers the side hole 111, and the back of the side cover 2 is connected to the electro-hydraulic actuator 4 located on the carrier plate 5.

[0020] like Figure 1 As shown, the motor 7 is fixedly installed in the middle of the three-leaf frame 6, and the three ends of the three-leaf frame 6 are fixedly connected to the top port of the weighing hopper 1. Through the three-leaf frame 6, the motor 7 and the weighing hopper 1 can be placed in the same weighing system.

[0021] A gap is left between the inner ring wall of the ring plate 10 and the surface of the weighing hopper 1 to avoid the ring plate 10 affecting the weighing of the weighing hopper 1.

[0022] The annular surface of the ring plate 10 is connected to the lifting platform connecting plate 11. By connecting the lifting platform connecting plate 11 to an external lifting platform, the entire weighing device can be moved up and down.

[0023] Furthermore, the top of the carrier plate 5 is fixedly connected to the surface of the weighing hopper 1.

[0024] Furthermore, part of the side strip hole 111 is located on the weighing hopper 1, and the other part is located on the short pipe 110.

[0025] Working principle: When the short tube 110 is lowered and inserted into the granules by means of an external lifting platform, the motor 7 drives the connected spiral blade 3 to rotate, so that the granules are sent along the short tube 110 through the rotating spiral blade 3 to the weighing hopper 1. The weight taken in one go is slightly more than the required weight. At this time, the short tube 110 resets. Since the weight taken in one go is slightly more than the required weight, under the weighing measurement of the weighing module 9, the motor 7 runs in reverse at a slow speed, driving the spiral blade 3 to rotate in the opposite direction, so that the granules in the middle fall off until the required weight is reached. When it is necessary to unload, the electro-hydraulic push rod 4, which is integrated with the weighing hopper 1, retracts and drives the connected side strip cover 2 to move out from the side strip hole 111, so that the granules inside the weighing hopper 1 are quickly discharged. At the same time, the motor 7 drives the spiral blade 3 to rotate in the opposite direction, which speeds up the unloading speed.

[0026] Compared with the existing technology, the difference is that the motor 7 drives the connected spiral blade 3 to rotate in both directions, which can not only transport the granular material into the weighing hopper 1, but also discharge the excess granular material, realizing the functions of automatic material picking, adjustment and weighing; the electro-hydraulic push rod 4 removes the connected side strip cover 2 from the side strip hole 111, and in conjunction with the reverse rotation of the spiral blade 3, speeds up the unloading speed and improves the working efficiency.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
