Description

Technical Field

[0001] The utility model belongs to the technical field of tire production equipment, and particularly relates to an automatic batching machine for tire production. Background Technique

[0002] In the processing and production of tires, in order to ensure the quality, it is necessary to accurately proportion each raw material and then put it into a kneading machine for mixing. Due to the large number of raw material types, the weighing and batching process is complex and cumbersome, and it is prone to deviation, affecting the quality of subsequent production. The authorized patent with the publication number of CN211968013U discloses an automatic batching device for rubber production, including a mixing box and an adjusting mechanism. On both sides of the top surface of the mixing box, batching boxes are fixedly welded. Between the inner walls of the batching boxes, fixing plates are fixedly welded. Second through holes are respectively opened at the centers of the fixing plates. On one side of the top surface of the mixing box, a fixing rod is fixedly welded. At the top of the fixing rod, a servo motor is fixedly installed through a mounting seat. The output shaft of the servo motor is fixedly sleeved with a gear. This patent solves the problem that various required batching components are poured into the box body at one time and then mixed, resulting in poor mixing effect between the required batching components during the mixing process, thereby reducing the quality of rubber and not meeting the needs of users. However, since the batching box is communicated with the mixing box, the next mixing can only be started after one mixing is completed, and the amount of mixing is limited, reducing the production efficiency and not being suitable for large-scale factory production. Therefore, an automatic batching machine for tire production is needed to solve the above technical problems. Content of the Utility Model

When the infrared sensor senses the receiving bucket below, each receiving bucket corresponds to each discharge pipe one by one, the electric rail vehicle stops moving, each electric switch valve I is opened, and materials are discharged into the corresponding receiving bucket.

[0017] The discharge pipe 11 is fixedly connected with a horizontal feeding pipe 6, a feeding screw 16 is arranged in the horizontal feeding pipe 6, the feeding screw 16 is connected with a stepping motor 12, the discharge end 13 of the horizontal feeding pipe 6 is connected with a receiving hopper 7, a weight sensor 8 is arranged on the receiving hopper 7, and an electric switch valve II is arranged at the discharge port 14 of the receiving hopper 7. This setting further improves the accuracy of batching. The raw materials in the storage tank 9 are transported into the receiving hopper 7 under the action of the feeding screw 16. When the raw materials in the receiving hopper 7 reach the weight corresponding to the ratio, the weight sensor 8 transmits a signal, the electric switch valve I is closed and the feeding screw 16 stops rotating, the raw materials no longer enter the receiving hopper 7, the electric switch valve II is opened, and the raw materials in the receiving hopper 7 enter the receiving bucket 3 of the electric rail vehicle 2 below, and the batching is more accurate.

[0018] A vibrator is arranged on the receiving hopper 7. The setting of the vibrator can make the materials in the receiving hopper 7 fully fall into the receiving bucket 3, further improving the accuracy of the ratio.

[0019] A control panel 15 is arranged on the receiving hopper 7, and the control panel 15 is electrically connected with the electric switch valve I, the electric switch valve II, the stepping motor 12, the vibrator, the infrared sensor and the weight sensor 8. The control principle of the control panel 15 and its connection with each component are all prior arts and will not be elaborated here. This setting improves the degree of automation.

The operation is convenient and efficient, improving the production efficiency.

[0021] Working principle: Different raw materials are stored in each storage tank 9. Each electric rail vehicle 2 continuously moves on the circular track 1 and moves one by one under each storage tank 9. When the electric switch valve of the storage tank 9 is opened, a certain amount of material is injected into the material receiving bucket 3 on the electric rail vehicle 2. Subsequently, the electric switch valve is closed. After the electric rail vehicle 2 moves to the next storage tank 9, the above operation is repeated until all the raw materials fall into the material receiving bag in the material receiving bucket 3 according to the proportion. Then, the material receiving bag is taken out, and the proportioned raw materials in the material receiving bucket 3 can be quickly transferred to the next process (mixing in a kneader). After the empty material receiving bucket 3 is sleeved with a new material receiving bag, the next material receiving operation is carried out on the electric rail vehicle 2. This setting can continuously complete multiple proportioning operations and supply materials to multiple kneaders, improving the production efficiency and being beneficial to large-scale production in the factory. At the same time, it can also supply materials to the same kneader multiple times, avoiding the problem of poor mixing effect caused by pouring all the raw materials at one time.
