[0043] During the material receiving process of the material distribution box 42, first, the upper end of the sealing frame 4332 is tightly attached to the lower end of the material discharging control valve 33 to seal and prevent the material from leaking out. Then, the two material receiving cylinders 4333 simultaneously pull out the corresponding baffles 4334 to connect the material receiving channel 4335 to the material distribution box 42, and then the two material discharging control valves 33 are opened synchronously to discharge the material. When the material in the material distribution box 42 contacts the material sensor 435, the two material discharging control valves 33 are closed to stop discharging, and then the pneumatic dustproof valve 433 is closed.

[0045] Please refer to Figure 7 , Figure 8 The fixed assembly 56 includes a fixed chain belt 561, a plurality of fixed sprockets 562 and two pull rods 563. One fixed sprocket 562 is fixed to the driving chain shaft 55, and the other plurality of fixed sprockets 562 are arranged at intervals on the inner side of the fixed frame 41 along the circumference of the fabric box 42. The fixed chain belt 561 is sequentially wound and meshed with the plurality of driving sprockets 54; each end of the fixed chain belt 561 is fixedly connected to a pull rod 563, and the end of the pull rod 563 away from the fixed chain belt 561 is fixedly connected to the fabric box 42.

[0046] In some embodiments, please refer to Figure 4 , Figure 5 , Figure 6The lifting mechanism 5 also includes a plurality of guide limit assemblies 57, which are arranged between the fixed frame 41 and the cloth box 42, and the cloth box 42 is slidably connected to the guide limit assemblies 57. The guide limit assemblies 57 include a mounting seat 571 and a limit wheel 572. The mounting seat 571 is fixedly arranged on the fixed frame 41, and the limit wheel 572 is rotatably arranged on the mounting seat 571. A groove is arranged on the circumferential side of the limit wheel 572, and the positive corner of the cloth box 42 is located in the groove, which can reduce the friction resistance of the cloth box 42 during the lifting process and ensure the balance of the cloth box 42, thereby improving the stability of the up and down movement of the cloth box 42 and the operation efficiency.

[0047] The mounting seat 571 includes a mounting plate 5711, an L-shaped support plate 5712, and two lugs 5713. One end of the mounting plate 5711 is fixed to the fixed frame 41, and the other end of the mounting plate 5711 is provided with a V-shaped avoidance groove, and the limiting wheel 572 is located above the avoidance groove. The support plate 5712 is screwed to the mounting plate 5711, and two lugs 5713 are provided on the side of the support plate 5712 facing the fabric box 42, and the limiting wheel 572 is rotatably connected between the two lugs 5713.

[0048] A wire encoder 58 is also provided at the lower end of the fixed frame 41, which can accurately control the height of the cloth box 42. At the same time, a mechanical limiter 59 can be provided on the cloth box 42 to ensure the safety of the equipment. Specifically, the mechanical limiter 59 can be provided as a rod-shaped structure.

[0049] The lifting process of the fabric box 42 is described in detail below.

[0050] First, a photoelectric sensor 67 is provided at the position of the driving wheel 64 of the walking active mechanism 6. After the photoelectric sensor 67 is aligned with the signal on the storage mechanism 3, it can be determined that the receiving port 4311 of the material distribution box 42 and the discharge hole 32 of the storage hopper 31 are accurately aligned, thereby improving the accuracy of docking and the efficiency of material receiving.

[0051] Second, the lifting motor 51 rotates forward to drive the lifting reducer 52, the driving sprocket 54, the driving chain belt 53, and the driving chain shaft 55 to rotate. The driving chain shaft 55 can drive the fixed chain belt 561 connected thereto to rotate. The fixed chain belt 561 is rewound under the action of multiple fixed sprockets 562, and the effective length of the fixed chain belt 561 is shortened, thereby pulling the corresponding pull rod 563 to lift. The four pull rods 563 drive the fabric box 42 to rise synchronously to the material receiving position. During the lifting process, the four limiting wheels 572 can limit the fabric box 42 to prevent the fabric box 42 from shaking or tilting, thereby ensuring the stability of operation.

[0052] Third, when the material box 42 is filled with materials, the lifting motor 51 reverses, the fixed chain belt 561 rotates in the opposite direction, the effective length of the fixed chain belt 561 increases, and the material box 42 descends to the material distribution position under its own weight, and the lifting motor 51 is turned off.

[0053] In some embodiments, please refer to Figure 1 , Figure 4 , Figure 5 , the frame 2 is provided with two guide rails 21, and the length direction of the guide rails 21 is consistent with the cloth direction. The walking active mechanism 6 includes a walking motor 61, a walking reducer 62, a transmission rod 63 and four driving wheels 64. The length direction of the transmission rod 63 is perpendicular to the cloth direction. The transmission rod 63 is arranged on one side of the fixed frame 41. The transmission rod 63 is connected to the walking reducer 62, and the output shaft of the walking motor 61 is fixedly connected to the walking reducer 62. Both ends of the transmission rod 63 are fixedly connected with a driving wheel 64, and the driving wheel 64 is slidably connected to the corresponding guide rail 21. Both ends of the other side of the fixed frame 41 are correspondingly provided with a driving wheel 64, and each guide rail 21 is provided with two driving wheels 64 at intervals along the length direction, which reduces the friction resistance of the cloth box 42 during the cloth movement, so that the cloth box 42 runs more stably and the cloth precision is higher.

[0054] The walking active mechanism 6 also includes a sensor 65, a sensor sheet 66 and a connecting shaft. The sensor sheet 66 is arranged on the fixed frame 41, and the sensor 65 is fixedly connected to the axis of one of the driving wheels 64 through the connecting shaft. The sensor sheet 66 is electrically connected to the sensor 65 to record the number of rotations of the driving wheel 64, so as to monitor the position of the cloth box 42 in real time, prevent the cloth box 42 from exceeding the range of the cloth and causing waste of materials, and improve the efficiency of cloth.

[0055] During the material laying process, the travel motor 61 drives the two driving wheels 64 thereon to rotate through the travel reducer 62 and the transmission rod 63, and the other two driving wheels 64 follow the material laying box 42. After the material is laid, the material laying port is closed, and the lifting mechanism 5 drives the material laying box 42 to rise to a set height so that the material duckbill 421 of the material laying box 42 is separated from the material tray 8, which can effectively prevent the material from dragging. Then the material laying box 42 is lowered to the material laying position, and the active travel mechanism 6 drives the material laying box 42 to move in the material laying direction, scraping off the excess material on the material tray 8, so that the material on the material tray 8 is laid more evenly.

[0056] Please refer to Fig. 9 A material distribution method of a double-discharge material distribution machine 1, comprising any of the double-discharge material distribution machines 1 described above, comprising:

[0057] Step S1, the storage hopper 31 discharges the material from the current discharge port corresponding to the material distribution box 42 into the material distribution box 42 until the material in the material distribution box 42 is loaded to the set position; the feed port of the material distribution box 42 and the current discharge port of the storage hopper 31 are closed;

[0058] Step S2, the lifting mechanism 5 drives the material distribution box 42 to descend to the material distribution height, and the walking active mechanism 6 drives the material distribution box 42 to reciprocate in a direction perpendicular to the conveying direction of the material tray 8; synchronously, the material distribution port of the material distribution box 42 is opened and the material is distributed in the material tray 8; until the material tray 8 is full of material, the material distribution box 42 is located below one of the discharge ports of the storage hopper 31;

[0059] Step S3: the lifting mechanism 5 drives the material distribution box 42 to rise to the material receiving position; and steps S1 and S2 are repeated to perform the next round of material distribution operation.

[0060] In some embodiments, step S2 also includes: when the material tray 8 is filled with materials, the material distribution box 42 closes the material distribution port and rises to a set height. The material distribution box 42 descends to the material distribution height, and the active travel mechanism 6 drives the material distribution box 42 to scrape off the excess material on the material tray 8. The material distribution box 42 is located below one of the material outlets of the storage hopper 31, which can effectively prevent the tailing phenomenon, so that the material distribution on the material tray 8 is more uniform and smooth.

[0061] In some embodiments, in step S3, the lifting mechanism 5 drives the material box 42 to rise to the material receiving position, and the conveyor table 7 removes the material tray 8 full of materials and delivers the next material tray 8 to be laid to the laying position, which can effectively avoid the material tray 8 being moved out of the laying position by the conveyor table 7 when it is not full of materials or is full of materials but not leveled, thereby improving the efficiency and quality of laying.

[0062] The workflow of step S1 is described in detail below.

[0063] Step S11, a photoelectric sensor 67 is provided at the driving wheel 64 of the walking active mechanism 6, and the photoelectric sensor 67 is aligned with the signal on the material storage mechanism 3;

[0064] Step S12, the lifting motor 51 rotates forward to drive the lifting reducer 52, the driving sprocket 54, the driving chain belt 53, and the driving chain shaft 55 to rotate.

[0065] Step S13, the two material receiving cylinders 4333 synchronously pull out the corresponding baffles 4334 to connect the material receiving channel 4335 to the material distribution box 42, and then synchronously open the two material discharging control valves 33 to discharge the material;

[0066] Step S14, when the material in the material distribution box 42 contacts the material sensor 435, the two discharge control valves 33 are closed to stop the discharge, and then the pneumatic dust prevention valve 433 is closed.

[0067] The workflow of step S2 is described in detail below.

[0068] Step S21, when the material distribution box 42 is full of materials, the lifting motor 51 is reversed, the fixed chain belt 561 rotates in the opposite direction, the effective length of the fixed chain belt 561 increases, and the material distribution box 42 is lowered to the material distribution position under the action of its own weight, and the lifting motor 51 is turned off;

[0069] Step S22, the travel motor 61 is started and drives the two driving wheels 64 thereon to rotate through the travel reducer 62 and the transmission rod 63, and the other two driving wheels 64 follow the fabric box 42 to travel;

[0070] Step S23, the material duckbill 421 of the material box 42 is opened to perform material laying operation; the active walking mechanism 6 drives the material box 42 to reciprocate within the material laying range until the material laying is completed;

[0071] Step S24, when the material tray 8 is filled with materials, the material distribution box 42 closes the material distribution opening and rises to a set height to separate the material distribution duckbill 421 from the materials in the material tray 8;

[0072] Step S25, the lifting mechanism 5 lowers the material distribution box 42 to the material distribution position, and the active walking mechanism 6 drives the material distribution box 42 to move along the material distribution direction to scrape off the excess material on the material tray 8, and the material distribution of the material tray 8 is completed.

[0073] The workflow of step S3 is described in detail below.

[0074] Step S31, the active walking mechanism 6 drives the material distribution box 42 to move so that the photoelectric sensor 67 is aligned with the signal on the material storage mechanism 3;

[0075] Step S32, the lifting mechanism 5 pulls the material box 42 to the material receiving position;

[0076] Step S33, the conveyor 7 starts and removes the tray 8 filled with materials and delivers the next tray 8 to be laid to the laying position;

[0077] Step S34, repeat steps S1 and S2 to carry out the next round of material laying operation.
