[0009] By adopting the above technical solution, the motor drives the screw to rotate and then drives the pressing plate to move, and the pressing plate drives the abutment to move. One side of the abutment presses the dye tank, and the position of the abutment is fixed. At this time, the pressing plate continues to move to press the piston part at the dye tank to feed the material into the mixing barrel.

[0011] By adopting the above technical solution, when the dye tank is pressed by the abutment, the mounting ring on the dye tank pushes the sliding ring to slide, driving the feeding spring to compress; when the pressing plate drives the abutment back, the feeding spring pushes the dye tank back, making it convenient for the next feeding.

The guide block pushes the pushing plate until one end of the clamping block is clamped at the sliding hole of the abutting frame. At this time, the position between the abutting frame and the limiting rod is fixed. The pressing plate drives the guide block to slide along the guide groove to press the dye tank for discharging.

The rolling connection reduces the friction between the guide block 1621 and the push plate 51 when sliding.

[0051] Reference Figure 8 and Figure 9 A material changing assembly is arranged in the box body 1, and the material changing assembly includes a material transfer rack 6 and a conveyor belt mechanism 7. A clamping mechanism 9 is arranged on the vertical material transfer rack 6, and the clamping mechanism 9 includes a clamping block 91 and a pushing member 92. A material transfer rod 61 is arranged horizontally on the top of the material transfer rack 6. One end of the material transfer rod 61 is located on the upper side of the through hole 21 of the feeding tray 2, and the end of the material transfer rod 61 away from the feeding tray 2 is located on the upper side of the placement groove 731 of the elastic conveyor belt 73. A slide groove 611 is opened at both ends and on the side facing downward, and the slide groove 611 is arranged along the length of the material transfer rod 61 The transfer rod 61 is located at the slide groove 611 and is provided with a guide rod 612. The clamping block 91 is slidably installed at the slide groove 611 of the transfer rack 6 and is slidably connected with the guide rod 612. A return spring 613 is sleeved on the guide rod 612. There are two groups of clamping blocks 91 which are relatively arranged at both sides of the dye tank 22. The clamping blocks 91 are located on the opposite sides and are provided with clamping grooves 911. The opposite sides of the connecting plate 225 are respectively clamped at the clamping grooves 911 of the clamping blocks 91 on both sides. There are two groups of clamping mechanisms 9 which are respectively located on both sides of the length direction of the transfer rod 61.

[0052] Referring to Figure 8 and Figure 9 Figure 9

[0053] The pushing member 92 includes a pushing cylinder 921 and a driving plate 922. The pushing cylinder 921 is vertically and upwardly arranged on the material-transfer rod 61. The driving plate 922 is horizontally arranged at one end of the piston rod of the pushing cylinder 921. At both ends of the driving plate 922 and on the downward side, a first rack 923 is vertically connected. Meshing teeth are arranged on both opposite sides in the length direction of the first rack 923. A first gear 924 meshing with both sides of the first rack 923 is rotatably installed on the material-transfer rod 61. A second gear 925 coaxially connected with the first gear 924 is arranged on the material-transfer rod 61. The clamping block 91 is connected with a second rack 926. The second rack 926 is horizontally slidably installed on the material-transfer rod 61. One side of the second rack 926 meshes with the second gear 925.

[0054] The pushing cylinder 921 drives the driving plate 922 to move, driving the first rack 923 to slide. The first rack 923 drives the first gear 924 to rotate. The first gear 924 drives the coaxially arranged second gear 925 to rotate. The second gear 925 drives the second rack 926 to slide, thereby driving the clamping blocks 91 to slide towards each other. The clamping blocks 91 clamp the opposite sides of the connecting plate 225 at the clamping grooves 911. When clamping on both sides, the dye tank 22 is not easily shaken. The two clamping blocks 91 slide synchronously to clamp the dye tanks 22 on the feeding tray 2 and the elastic conveyor belt 73. During feeding, the lifting cylinder 81 drives the support plate 82 to move, thereby driving the material-transfer rack 6 to move. The clamping blocks 91 on the material-transfer rack 6 drive the spare dye tanks 22 on the elastic conveyor belt 73 and the dye tanks 22 to be replaced on the feeding tray 2 to move to the disengaging position at the same time. At this time, the rotating motor 83 drives the material-transfer rack 6 to rotate, driving the dye tanks 22 on both sides to change positions. The lifting cylinder 81 then drives the support plate 82 to move down to place the dye tanks 22 on both sides, and at the same time, the operations of discharging and feeding are completed.

[0055] When the dye tank 22 needs to be replaced, the lifting cylinder 81 drives the support plate 82 to drive the material transfer rack 6 to move to a position where the clamping block 91 is located at the dye tank 22. The pushing cylinder 921 drives the driving plate 922 to drive the clamping block 91 to clamp the dye tank 22. The clamping blocks 91 on both sides synchronously clamp the dye tanks 22 on the feeding tray 2 and the elastic conveyor belt 73. The lifting mechanism 8 drives the material transfer rack 6 to rise until the dye tank 22 is disengaged from the feeding tray 2 and the elastic conveyor belt 73. At this time, the material transfer rack 6 rotates to drive the dye tanks 22 on both sides to change positions. The lifting mechanism 8 lowers the material transfer rack 6, and the clamping mechanism 9 releases the dye tank 22 to complete the material replacement operation.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
