DETAILED DESCRIPTION
[0025] As Figures 1-7As shown, a resin automatic stirring system comprises a support 1, a lifting device, a containing frame 2, a control system, the containing frame 2 is upwardly open, the lifting device is located directly above the containing frame 2, the execution end of the lifting device is provided with a downward stirrer, a switch door 3 is rotatably arranged on the front side wall of the containing frame 2, a placing table 4 is arranged in the containing frame 2 through a linear movement driver, a weighing instrument 5 is arranged on the placing table 4, a fixer is arranged on the weighing table 6 of the weighing instrument 5, the moving direction of the placing table 4 driven by the linear movement driver is perpendicular to the side wall of the containing frame 2 on which the switch door 3 is arranged and parallel to the upper surface of the placing table 4, a mechanical control assembly for controlling the opening and closing of the switch door 3 is arranged on the placing table 4, at least two pumps 7 are fixedly arranged on the opening edge of the containing frame 2, one flow control valve 8 is arranged at the outlet end of each pump 7, and the outlet end of each flow control valve 8 is within the opening range of the containing frame 2; when the execution end of the stirrer is located in the containing frame 2, each flow control valve 8 is provided with a preset distance between the outlet end and the stirrer, and the control system is signal connected with the lifting device, the weighing instrument 5, the flow control valve 8, the pump 7, the linear movement driver and the fixer.
[0026] In use, the mass of resin to be made is input into the control system via the input keyboard 32, the door 3 is opened, the bucket 30 is placed on the weighing platform 6, and then a start command is input from the input keyboard 32. The control system controls the door 3 to close, and after the door 3 is closed, the fixing device fixes the bucket 30. The control system controls the pumps 7 and the flow control valves 8 to draw the raw materials from the raw material storage tanks 31 into the bucket 30 according to the proportions of the raw materials input by the worker from the input keyboard 32 (which can also be pre-stored in the control system). Then, the control system controls the lifting device to lower, so that the stirrer extends into the bucket 30 to stir the materials in the bucket 30. After the stirring is completed, the control system controls the stirrer to stop stirring, and controls the lifting device to rise and leave the bucket 30. Then, the control system controls the linear movement driver to drive the placement table 4 to extend from the door 3 of the holding frame 2. In this process, because of the mechanical control assembly, the linear movement driver drives the placement table 4 to extend from the door 3 of the holding frame 2 while slowly opening the door 3, that is, at this time the weighing platform 6 is away from directly below the stirrer, so as to facilitate the worker to take away the stirred resin. Then, the control system controls the fixing device to release the fixing of the bucket 30, so that the worker can take away the vertical. Because of the mechanical control assembly, the linear movement driver drives the placement table 4 to pull into the holding frame 2 from outside the holding frame 2 while slowly closing the door 30, which mainly plays a safety protection role to prevent the worker from adding materials or touching the stirrer during the working of the stirrer to cause a safety accident. The flow control valve 8 is used to control the amount of raw materials entering the bucket 30. The weighing platform 6 is used to give a signal feedback to the control system after the raw materials enter the bucket 30, especially when the relationship between the flow control valves 8 is the ratio of flow. When the total amount input into the bucket 30 by all the flow control valves 8 reaches the preset value, the weighing platform 6 sends the total weight input into the bucket 30 to the control system, and the control system controls all the pumps 7 to stop working. In this way, the raw material proportioning and stirring are integrated, so that the worker does not need to carry the raw materials from the raw material proportioning station to the stirring station during the resin stirring process, thereby reducing the workload of the worker and improving the stirring efficiency.

After the arrangement, after the barrel 30 is placed on the weighing instrument 5, the control system controls the extension rod 24 to be elongated, and the left clamping jaw 20 and the right clamping jaw 21 clamp the barrel 30, so that the barrel 30 is prevented from moving or shaking under the stirring of the stirrer and the rotation of the resin in the barrel 30.
[0032] As a preferred mode, the left clamping jaw 20 and the right clamping jaw 21 are arranged at the top end of the left side plate 22 and the top end of the right side plate 23 respectively.
