[0024] Referring to Figure 1 According to the embodiment of the utility model discloses a kind of quantitative discharge systems, including machine table 11, the machine table 11 is fixed with material cylinder 13 by support frame 12, the bottom of the material cylinder 13 is connected with obliquely extended discharge pipe 14, pneumatic ball valve 15 is contained in the discharge pipe 14, electronic scale 16 is also mounted on the machine table 11, and receiving bucket 17 is provided on the electronic scale 16, and the discharge pipe 14 can be opposite to the receiving bucket 17.

[0025] Further including control system 22, the control system 22 includes button and display screen, and the control system 22 is electrically connected to the electronic scale 16 and pneumatic ball valve 15.

[0026] When needing to discharge, staff can input the required discharge weight by the button, and execute discharge work, at this time, the pneumatic ball valve 15 is opened, and the material in the material cylinder 13 will enter receiving bucket 17 through discharge pipe 14 under the action of gravity.

[0027] When the electronic scale 16 detects that the weight of the material in the receiving barrel 17 meets the standard, the control system 22 controls the automatic closing of the pneumatic ball valve 15, and the quantitative discharging is completed.

[0028] It is necessary to additionally explain that the specific way of electrically connecting and controlling the electronic scale 16 and the pneumatic ball valve 15 by the control system 22 is the conventional setting of the prior art, which will not be described here.

[0029] In the embodiment, the discharging pipe 14 comprises a first section pipe 91, a middle pipe 92 and a last section pipe 93. One end of the first section pipe 91 is connected to the material cylinder 13, and the other end of the first section pipe 91 is connected to the middle pipe 92 through a first manual ball valve 18. The other end of the middle pipe 92 is connected to the last section pipe 93 through the pneumatic ball valve 15. The last section pipe 93 is curved, and the last end of the last section pipe 93 faces downward.

[0030] When the first manual ball valve 18 is in the closed state, the device is stopped, and the opening of the pneumatic ball valve 15 does not affect the discharging.

[0031] In order to avoid the downward bending of the discharging pipe 14 due to gravity, the middle pipe 92 and the pneumatic ball valve 15 are further fixed to the support frame 12 through fasteners.

[0032] In addition, in order to improve the monitoring degree of the material in the material cylinder 13 and facilitate the cleaning and feeding of the material cylinder 13, a vertical pipe 19 is vertically arranged in the bottom surface of the material cylinder 13. The lower end of the vertical pipe 19 is provided with a second manual ball valve 20. A temperature measuring module 21 is arranged in the bottom surface of the material cylinder 13. The temperature measuring module 21 is electrically connected to the control system 22, so that the material temperature in the material cylinder 13 can be displayed on the display screen in the control system 22. A feeding pipe 23 is arranged at the upper end of the material cylinder 13, and the feeding pipe 23 is closed by a cover plate.

[0033] In the second embodiment of the quantitative discharging system, in order to avoid the interference and collision between the receiving barrel 17 and the discharging pipe 14 and the pneumatic ball valve 15 when the staff places the receiving barrel 17 on the electronic scale 16, a support table 24 is slidably connected to the left and right of the machine table 11, and the electronic scale 16 is fixed to the support table 24. A pneumatic cylinder 25 for controlling the left and right movement of the support table 24 is arranged on the machine table 11, and the pneumatic cylinder 25 is electrically connected to the control system 22.

[0034] That is, in the initial state, the electronic scale 16 is at the rightmost position, when the operator places the receiving bucket 17 on the electronic scale 16, the electronic scale 16 senses the gravity of the electronic scale 16 itself, after a certain delay, the control system 22 drives the electronic scale 16 and the receiving bucket 17 to the leftmost position through the air cylinder 25, and at this time, the receiving bucket 17 is opposite to the tail section pipe 93, then the operator can control the pneumatic ball valve 15 to open through the control system 22, and make the material in the barrel 13 flow into the receiving bucket 17, after the electronic scale 16 senses that the weight reaches the input value, the pneumatic ball valve 15 is automatically closed, and then the air cylinder 25 controls the electronic scale 16 to move to the rightmost position, so that the receiving bucket 17 is no longer under the tail section pipe 93, so as to facilitate the taking out of the receiving bucket 17.

[0035] In addition, the machine table 11 is further provided with a baffle 26 for shielding the pneumatic ball valve 15 and the discharge pipe 14, the baffle 26 extends to the right and then bends downward, further protecting the discharge pipe 14.

[0036] In order to prevent the residual material in the tail section pipe 93 from dropping after the receiving bucket 17 is pushed away from the tail section pipe 93, the machine table 11 is further provided with a collecting box 27, which is located under the support table 24 and opposite to the discharge pipe 14.

[0037] It is necessary to additionally explain that the piston rod of the air cylinder 25 extends out of and is connected to the support table 24, and the collecting box 27 and the tail section pipe 93 are staggered in front and back, and the collecting box 27 is detachable for cleaning.

[0038] The above only describes specific embodiments of the present application, but the technical features of the present application are not limited to this, any person skilled in the art in the field of the present application, the changes or modifications made are covered in the patent range of the present application.
