Technical Field
[0001] The utility model relates to the field of plastic particle production, and more specifically to a mixer feeding device used for plastic particle production. Background Art
[0002] During the preparation of plastic particles, depending on the different particles being prepared, several materials need to be sucked into the mixer under negative pressure, and there are requirements for the weight ratio of the materials. With the rapid development of the plastics industry, the quality requirements for plastic particles are getting higher and higher. As the raw material of plastic products, the quality of plastic particles directly affects the performance and service life of the final product.
[0003] When mixing multiple materials, traditional feeding devices often rely on manual operation or simple mechanical devices to mix the materials. This method is easily affected by human factors, such as operating errors and lack of concentration, resulting in low material ratio accuracy and affecting the quality of the final product. In addition, when the materials are about to run out, the feeding device often lacks an effective early warning mechanism, making it difficult for workers to find and replenish materials in time, thus causing production interruptions, which not only affects production efficiency, but may also cause unnecessary losses. In addition, the feeding device requires workers to perform multiple manual operations during the feeding process, which is not only cumbersome and time-consuming, but also prone to errors.

[0031] The fixed plate 2 is connected to a circular ring portion 10 through an electric lifting rod 2.1, and the movable end of the electric lifting rod 2.1 is connected to an L-shaped bracket 2.2, and the L-shaped bracket 2.2 is fixedly connected to the circular ring portion 10, and a plurality of snap rings 10.1 are connected to the circular ring portion 10, and the snap rings 10.1 have locking bolts 10.2.

[0032] Working principle: The feeding device of the present application needs to mix multiple materials in a certain proportion according to the requirements of the prepared plastic particles. First, add materials to each barrel. A weight sensor is installed in each containing tank to monitor the weight of the material in the barrel in real time. When the material is sucked into the mixer, the weight sensor will record the weight difference before and after the suction, so as to accurately calculate the amount of material added. When the material in a barrel is lower than the set threshold, the weight sensor will send a signal to remind the worker that material needs to be added to the barrel. This automatic feeding reminder greatly improves production efficiency and avoids production interruptions due to insufficient materials.
[0033] When adding materials, first the electric lifting rod drives the circular ring part to rise, so that the suction tube is separated from the barrel, and the rotating rod is lifted upward by the handle, so that the pressure rod presses down the clamping plate, thereby releasing the limit on the rotating disk, and then the control unit controls the rotation of the rotating disk, and rotates the barrel to the feeding position (such as the position where the limit unit is located). After the feeding is completed, the rotating disk is rotated back to its original position, and then the clamping plate is clamped to the clamping block to limit the rotating disk. Finally, the electric lifting rod drives the circular ring part to descend, so that the suction tube is inserted into the barrel again to perform the suction operation.
[0034] Although the present invention has been illustrated and described with respect to preferred embodiments, it should be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
