[0020] like Figure 1-3 As shown, a quantitative discharging device for recycling rubber powder masterbatch of waste tires comprises a supporting base plate 1, a supporting platform 2, a quantitative cylinder 3 and a mobile feeding unit; the supporting base plate 1 has a corresponding supporting force; the supporting platform 2 has a corresponding supporting force and is erected above the supporting base plate 1; the quantitative cylinder 3 has a corresponding accommodating chamber, and is provided with a plurality of chambers and is installed at intervals at the bottom of the supporting platform 2 along the length direction of the supporting platform 2, the upper end opening penetrates the supporting platform 2, and the lower end is connected to a discharging pipe 4; the mobile feeding unit moves along the length direction of the supporting platform 2, and is used for discharging materials into the quantitative cylinder 3 at different discharging positions. During the movement, the mobile feeding unit feeds materials into the quantitative cylinder 3 in batches, and stores the materials quantitatively in the quantitative cylinder 3 respectively, so as to facilitate the quantitative cylinder 3 to discharge materials separately and in small batches, which is more convenient to control and improves the accuracy of the discharge amount.

[0021] The discharge pipe 4 of the quantitative cylinder 3 is provided with a valve for opening and closing the discharge pipe 4. The support base plate 1 is provided with a weighing platform 5 corresponding to the quantitative cylinder 3. The weighing platform 5 is electrically connected to the controller, and the controller is electrically connected to the valve to receive feedback from the weighing platform 5 and control the opening and closing of the valve. When the material is collected on the weighing platform 5 to a predetermined weight, the controller receives feedback from the weighing platform 5, controls the corresponding valve of the discharge pipe 4 to close, and stops discharging;

[0022] In some preferred embodiments, the mobile feeding unit includes a mobile support part 6, which has a corresponding supporting force and moves along the length direction of the mobile platform. Here, preferably, mobile guide rails are installed on both sides of the length direction of the mobile platform, and the mobile support part 6 moves stably along the mobile guide rails and supports the material receiving barrel 7; the material receiving barrel 7 is connected to the mobile support part 6 and moves with the mobile support part 6. The bottom is connected to a discharge channel 8 for discharging materials into the quantitative cylinder 3. A pull-out baffle plate 9 is provided at the top of the discharge channel 8 for closing and opening the discharge channel 8. Here, it should be noted that the material receiving barrel 7 is mounted on the supporting working surface of the mobile support part 6, and the discharge channel 8 at the bottom of the material receiving barrel 7 passes through the mobile support part 6. When it moves to the corresponding position, it can discharge materials into the quantitative cylinder 3 below. Furthermore, the pull-out baffle plate 9 is pulled out to different positions to adjust the size of the material outlet at the top of the discharge channel, thereby adjusting the discharge speed.

[0023] It should be noted that the mobile feeding unit is connected to a mobile drive, and the mobile drive is configured to provide the mobile feeding unit with a driving force for moving along the length direction of the support platform 2. Specifically, the mobile drive can be a hydraulic push rod 15, which is connected to the material receiving barrel 7 to push the material receiving barrel 7 to slide along the mobile guide rail.

[0024] In some preferred embodiments, a stirring and dispersing assembly is provided in the material receiving barrel 7, which is rotatably mounted inside the material receiving barrel 7 and connected to a rotary drive 16, so as to perform corresponding stirring and dispersing operations inside the material receiving barrel 7. Specifically, the stirring and dispersing assembly includes a rotating shaft 10, the top end of which is rotatably mounted on a supporting cross bar 11 at the top end of the material receiving barrel 7, and the bottom end of which extends downward along the central axis of the material receiving barrel 7; a supporting rod 12, which is mounted on the rotating shaft 10, and the section extending in the same direction as the rotating shaft 10 is in contact with the inner wall of the material receiving barrel 7 during rotation, so as to perform corresponding wall scraping operations; a stirring cross bar 13, which is fixed on the rotating shaft 10 in a direction perpendicular to the central axis of the rotating shaft 10, and the length of the parts located on both sides of the rotating shaft 10 has a predetermined length difference, and a fixed ball 14 is mounted at the fixed distal end of the shorter part. In this embodiment, the rotating shaft 10 is connected to the rotating drive 16, and the rotating drive 16 is installed on the supporting cross bar 11. The top of the rotating shaft 10 is fixedly connected to the output end of the rotating drive 16. After the rotating drive 16 is started, the rotating motor output end rotates to drive the rotating shaft 10 to rotate, and the rotating shaft 10 rotates to drive the supporting rod 12 and the stirring cross bar 13 and the fixed ball 14 on the stirring cross bar 13 to rotate, wherein the outer side of the supporting rod 12 can be equipped with a brush, and the inner wall of the docking barrel 7 is used to hang the wall fixed ball 14 and the stirring cross bar 13 to rotate. Since the stirring cross bar 13 has different lengths on both sides of the rotating shaft 10, when rotating, the inner and outer rings of the material body are stirred to dissipate heat from the material body to avoid adhesion, and the material body is dispersed during the stirring process. When in use, the device is placed at a suitable operating position and installed at the discharging position of the rubber powder masterbatch granulation, and since the receiving barrel is movable, it is convenient to match the receiving position according to the actual situation.

[0025] When the receiving barrel 7 receives the material, the rotary drive 16 can be started to make the support rod 12, the stirring cross bar 13 and the fixed ball 14 rotate in the material, stirring and dispersing the material, and cooling the material at the same time to prevent the material from sticking together, facilitate discharge and avoid blockage;

[0026] After the material receiving is completed, the movable material receiving cylinder 7 can discharge the material quantitatively into multiple linearly arranged quantitative cylinders 3 in turn, and the material in the material receiving cylinder 7 is discharged into the quantitative cylinder 3 through the discharge channel 8. The sensor in the quantitative cylinder 3 can detect the height of the internal material body, and the discharge channel can be closed when the volume or height is predetermined; then the material is discharged through the quantitative cylinder 3, and further weighed by a weighing sensor. When the predetermined weight is reached, the controller closes the valve of the discharge pipe 4 to improve the accuracy of the discharge; at the same time, the quantitative cylinder 3 can be used to discharge materials at multiple locations at the same time to improve the efficiency of discharge and bagging.

[0027] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the scope of protection of the utility model.
