[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Example

[0026] like Figure 2 As shown, a double-carriage material distributing machine is composed of a frame 1, a left material distributing car 6 (including a left frame, a left conveyor belt, a transmission system and other components), a right material distributing car 7 (including a right frame, a right conveyor belt, a transmission system and other components), etc. The frame 1 is fixed to the outside of the feeder bin 5, and the left material distributing car 6 and the right material distributing car 7 make stepping motion in the same direction on the guide rail of the frame 1, that is, the left material distributing car 6 and the right material distributing car 7 move in the same direction and at the same stepping motion speed. When a connecting rod is provided between the left material distributing car and the right material distributing car, only one transmission system is used, and the left material distributing car and the right material distributing car are mechanically connected by the connecting rod to ensure that the stepping motion speeds of the left material distributing car and the right material distributing car are the same; the left and right conveyor belts both convey materials in the direction of the front of the left material distributing car 6 and the right material distributing car 7, and the conveying speeds of the left and right conveyor belts are the same. The left limit position A of the material distribution car is the leftmost side of the feeder silo 5. At this time, the front of the left material distribution car 6 should not exceed the leftmost side of the inner wall of the feeder silo 5 (to prevent the material on the left conveyor belt from falling outside the feeder silo 5); the right limit position B of the material distribution car is the rightmost side of the feeder silo 5. At this time, the front of the right material distribution car 7 should not exceed the leftmost side of the inner wall of the feeder silo 5 (to prevent the material on the left conveyor belt from falling outside the feeder silo 5); proximity switches are installed at the left and right limit positions respectively; in addition, the upstream conveyor belt 4 needs to be moved to the top of the center of the feeder silo 5.

[0027] Working principle of the double-carriage material distribution machine: in the initial position, the left material distribution car 6 and the right material distribution car 7 are placed symmetrically with respect to the center line of the feeder silo 5. At this time, the material directly enters the feeder silo 5 from the upstream conveyor belt 4; as the left material distribution car 6 and the right material distribution car 7 synchronously step forward to the left, the right material distribution car 7 enters the area below the upstream conveyor belt 4. At this time, the material enters the feeder silo 5 from the upstream conveyor belt 4 through the conveyor belt of the right material distribution car 7; when the front of the left material distribution car 6 reaches the left limit position A, the left material distribution car 6 and the right material distribution car 7 move in the opposite direction (to the right); as the left material distribution car 6 and the right material distribution car 7 step forward to the right The left material distribution vehicle 6 enters the area below the upstream conveyor belt 4. At this time, the material enters the feeder bin 5 from the upstream conveyor belt 4 through the conveyor belt of the left material distribution vehicle 6; and the right material distribution vehicle 7 distributes the material to the right side of the feeder bin 5; when the head of the right material distribution vehicle 7 reaches the limit position B, the left material distribution vehicle 6 and the right material distribution vehicle 7 move in the opposite direction (to the left) again; as the left material distribution vehicle 6 and the right material distribution vehicle 7 move step by step to the left, the right material distribution vehicle 7 enters the area below the upstream conveyor belt 4 again, at this time, the single distribution of the right feeder bin 5 is completed, and the left material distribution vehicle 6 starts to distribute the material to the left feeder bin 5. This cycle is repeated until the distribution is completed.

[0028] like Figure 3 As shown, this embodiment also provides a material placing method using the double-car material placing machine as described above, comprising the following steps:

[0029] Step 1: The left material distribution vehicle 6 and the right material distribution vehicle 7 are located at the initial position, and the material directly enters the feeder silo 5 from the upstream conveyor belt 4 to start distribution;

[0030] Step 2, the left material distribution car 6 and the right material distribution car 7 move step by step to the left synchronously, and the right material distribution car 7 gradually enters the area below the upstream conveyor belt 4, and the material enters the feeder silo 5 from the upstream conveyor belt 4 through the conveyor belt of the right material distribution car 7;

[0031] Step 3, determine whether the left cloth-making vehicle 6 head reaches the left limit position A (whether the proximity switch at point A is triggered). If not, return to step 2 and repeat the process. If reached, enter the process of whether to end the cloth-making judgment.

[0032] Step 4, determine whether the cloth making is finished. If the cloth making is finished, the left cloth making vehicle 6 and the right cloth making vehicle 7 return to the initial position synchronously, and the cloth making is finished; if the cloth making is not finished, the left cloth making vehicle 6 and the right cloth making vehicle 7 synchronously step to the right;

[0033] Step 5, the left material distribution car 6 and the right material distribution car 7 move synchronously to the right, the left material distribution car 6 gradually enters the area below the upstream conveyor belt 4, and the material enters the feeder silo 5 from the upstream conveyor belt 4 through the conveyor belt of the left material distribution car 6; at the same time, the right material distribution car 7 gradually exits the upstream conveyor belt 4 area, and the right material distribution car 7 starts to distribute the material to the right side of the feeder silo 5;

[0034] Step 6, determine whether the head of the right cloth car 7 has reached the right limit position B (whether the proximity switch at point B is triggered). If not, return to step 5 and repeat this cycle; if reached, enter the process of whether to end the cloth judgment;

[0035] Step 7, determine whether the cloth making is finished. If the cloth making is finished, the left cloth car 6 and the right cloth car 7 return to the initial position synchronously, and the cloth making is finished; if the cloth making is not finished, return to step 2 and repeat this cycle.

[0036] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
