[0044] The feeding assembly 2 includes a feeding pipe 201 fixedly installed on the top of the processing equipment 1. The inner diameter of the feeding pipe 201 is larger than the external connection of the feeding pipe 3121. A push rod 202 is provided inside the feeding pipe 201. A fixing rod 203 is installed between the push rod 202 and the inner wall of the feeding pipe 201. Before the masterbatch enters the conveying box 306, the bottom end of the feeding pipe 3121 contacts the bottom plate 305, pushing the guide longitudinal rod 3124 to move upward a short distance, so that the conductive rod 3129 is out of contact with the first contact 31211, and the fan 3112 is powered off and stopped, which is convenient for the masterbatch to enter. When feeding, the push rod 202 pushes the guide longitudinal rod 3124 upward a long distance, so that the conductive rod 3129 contacts the second contact 31212, so that the electromagnet 31197 is energized, and the second connecting hole 31192 is opened, so that the negative pressure inside the conveying box 306 disappears, which is convenient for the masterbatch loading.

[0045] Working principle: When working, first turn on the first motor 304 to control the longitudinal sliding frame 302 to move toward the side away from the processing equipment 1, drive the conveying box 306 to move to the top of the bottom plate 305, and then drive the conveying box 306 to move downward through the second motor 309 until the bottom end of the discharge pipe 3121 contacts the bottom plate 305. Since the bottom end of the guide longitudinal rod 3124 is located below the bottom end of the discharge pipe 3121, the guide longitudinal rod 3124 is pushed upward, so that the stopper 3123 moves upward, and the stopper 3123 will not enter the inside of the conveying box 306, and the discharge pipe 3121 is still closed. At this time, the movable plate 3128 moves upward, so that the two ends of the conductive rod 3129 are separated from the two first contacts 31211, so that the fan 3112 is in a power-off state to avoid affecting the masterbatch feeding;

[0046] Then, the two movable plates 3102 are pulled outward to open the top of the conveying box 306, and the masterbatch placed in the sealed bag is poured into the conveying box 306 until the amount required for processing is reached and the material surface is below the side tube 3111. After storage, the movable plate 3102 is released, so that the movable plate 3102 moves back under the elastic force of the first spring 3106, and the top of the conveying box 306 is closed;

[0047] Then, the conveying box 306 is controlled to move upward. After moving upward, the block 3123 moves upward under the pressure and its own gravity, thereby driving the movable plate 3128 to move downward, so that the end of the conductive rod 3129 contacts the first contact 31211 again, so that the fan 3112 is energized, driving the air inside the conveying box 306 to be continuously discharged through the side tube 3111. After the fan 3112 is turned on, the air inside the conveying box 306 continuously enters the inside of the side tube 3111, thereby pushing the baffle 3114 to move outward, so that the first connecting hole 3115 is connected to the outside, so that the air is discharged from the first connecting hole 3115. After the amount of air inside the conveying box 306 is continuously reduced, the baffle 3114 moves back under the elastic force of the second spring 3117, thereby closing the side tube 3111, reducing the amount of air inside the conveying box 306, reducing the probability of the masterbatch contacting with air and moisture, effectively preventing the masterbatch from being oxidized and damp, and protecting the masterbatch during the feeding process.

[0048] When the movable tube 3113 moves toward the outside, the movable block 31183 is pulled upward by the connecting rod 31185, and the extrusion block 31187 is simultaneously driven to move upward, so that the inclined surface of the extrusion block 31187 contacts the inclined surface of the pressure block 3107, and then the movable block 31183 continues to move upward, so that the rod groove 31188 is continuously compressed, and then the extrusion block 31187 is pressed against the pressure block 3107 by the elastic force of the rod groove 31188, so that the ends of the two movable plates 3102 are tightly attached, and the movable plate 3102 is tightly attached to the inner wall of the conveying box 306, so that when exhausting, the outside air will not enter the inside of the conveying box 306 from the top of the conveying box 306, thereby improving the exhaust effect, and the fan 3112 is always in a state during the feeding process, which can ensure that the amount of air inside the conveying box 306 is at a small level;

[0049] After the conveying box 306 is lifted to a height higher than the top of the processing equipment 1, the conveying box 306 is controlled to move toward the side of the processing equipment 1 until the conveying box 306 moves to the top of the processing equipment 1 and the discharge pipe 3121 is located directly above the feed pipe 201, and then the conveying box 306 is controlled to move downward. When the conveying box 306 moves downward, the discharge pipe 3121 enters the feed pipe 201. At this time, the top rod 202 inside the feed pipe 201 is inserted into the discharge pipe 3121, and the guide longitudinal rod 3124 is inferred to push the stopper 3123 to move upward into the conveying box 306. At this time, the masterbatch inside the conveying box 306 enters the processing equipment 1 from the discharge pipe 3121 and the feed pipe 201 for processing, and the top of the stopper 3123 is set in a conical shape to facilitate discharge and avoid obstruction to the masterbatch;

[0050] After the stop block 3123 moves upward and enters the interior of the conveying box 306, the movable plate 3128 moves upward until it contacts the top wall of the power box 31210, so that the two ends of the conductive rod 3129 contact the two second contacts 31212 respectively, causing the fan 3112 to be powered off and shut down. The electromagnet 31197 is energized to generate magnetic force, which produces a repulsive force on the magnetic block 31196, pushing the movable ring 31194 to move toward the side of the fixed ring 31193, opening the second connecting hole 31192. At this time, air can enter the conveying box 306, relieving the negative pressure effect inside the conveying box 306, thereby facilitating the smooth unloading of the masterbatch in the conveying box 306.
