The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1 to 8, the present invention provides a technical solution:

example (b):

as shown in fig. 1-5, an automatic feeding device for bag loading materials comprises a conveying conveyor belt 1, a bin 2 and a bag breaking mechanism 3, wherein the bag breaking mechanism 3 comprises a feeding bin 4, a bag cleaning turntable 5, a bag breaking member 6 and a driving mechanism 7, the feeding bin 4 is of a structure with openings at two ends, the bottom end of the feeding bin 4 is communicated with the bin 2, the section of the upper half of the feeding bin 4 is trapezoidal, the section of the lower half of the feeding bin 4 is square, and the discharge end of the conveying conveyor belt 1 is positioned above the feeding bin 4; the lower half part of the feeding bin 4 is provided with a horizontal grid 8, the bag breaking pieces 6 are multiple, the multiple bag breaking pieces 6 are connected with the driving mechanism 7 through a first connecting shaft 9, the bag breaking pieces 6 are arranged below the horizontal grid 8, the multiple bag breaking pieces 6 correspond to grid holes of the horizontal grid 8 respectively, the bag cleaning turntable 5 is coaxially provided with a second connecting shaft 10, the second connecting shaft 10 is connected with the feeding bin 4 through a turntable support, and the second connecting shaft 10 is connected with the driving mechanism 7 through a belt; the bag cleaning turntable 5 is provided with a bag claw 11 along the circumferential direction, and the bag claw 11 is used for taking out empty bags in the feeding bin 4 when the bag cleaning turntable 5 rotates.

As shown in fig. 3 and 4, the bag breaking member 6 is a circular saw blade or a circular blade, and the driving mechanism 7 is a motor. Wherein, a first belt pulley is arranged on the second connecting shaft 10, a second belt pulley is arranged on the output shaft of the driving mechanism 7, and the second connecting shaft 10 is connected with the driving mechanism 7 through a belt, the first belt pulley and the second belt pulley. The bag grippers 11 are arranged 4 or 6, preferably 4, along the circumference of the bag cleaning rotating disc 5.

As shown in fig. 1, a plurality of partition plates 18 are uniformly distributed on the conveying belt 1 along the running direction thereof. A bag material is arranged between two adjacent partition plates 18, so that the bag material can be uniformly distributed, and meanwhile, the bag material can be prevented from sliding off.

The working principle is as follows: the bagged material is transported to the top of the feeding bin 4 by the material transporting conveyor belt 1 and enters the feeding bin 4 from the top of the feeding bin 4. The driving mechanism 7 drives the bag breaking piece 6 to rotate, so that the material bag is broken to form an opening, the materials in the material bag enter the storage bin 2 through the opening under the action of gravity, and the discharged material bag still stays in the feeding bin 4 due to the interception of the horizontal grating 8. The driving mechanism 7 drives the bag breaking piece 6 to rotate and simultaneously drives the bag cleaning turntable 5 to rotate through a belt, and the bag claw 11 on the bag cleaning turntable 5 hooks out the material bag left in the feeding bin 4 when the bag cleaning turntable 5 rotates. When the rotating is continued until the bag claw 11 faces downwards, the material bag automatically breaks away from the bag claw 11, and the bag cleaning of the material bag is completed.

In the process, the use conditions of bag breaking, feeding and bag cleaning are met through the presetting of the running speed of the material conveying conveyor belt 1 and the rotating speed of the bag cleaning turntable 5. The residence time of the bagged materials in the feeding bin 4 can be ensured individually by controlling the running speed of the clinker conveyor belt and the uniform distribution of the bagged materials in the clinker conveyor belt at intervals, so that the materials in the material bags and enough time are ensured to enter the bin 2. The bag breaking pieces 6 can break the material bag into a plurality of openings to ensure the discharging speed. The rotating speed of the bag cleaning rotating disc 5 is controlled to ensure the retention time of the bag filling material between two adjacent bag claws 11, and when the material discharging in the material bag is finished, the next bag claw 11 just enters the upper part of the horizontal grating 8 to grab the material bag 11. To ensure that the bag breaking member 6 breaks the material bag first, the diameter ratio of the first belt pulley and the second belt pulley can be 5: 1. 4: 1. or 3:1, the arrangement is such (for example 5:1) that the bag cleaning turntable 5 rotates 1/5 of a turn when the driving mechanism 7 drives the bag breaking member 6 to rotate one turn.

The automatic feeding device disclosed by the invention realizes automatic feeding, bag breaking and bag cleaning, manual carrying and bag dismantling are not needed, and potential safety hazards are effectively avoided.

Further, as shown in fig. 4, a plurality of bag breaking members 6 form two parallel bag breaking assemblies, and the rotation directions of the two bag breaking assemblies are opposite. The two groups of bag breaking assemblies and the driving mechanism 7 realize reverse transmission of rotation through gear transmission, and specific connection relation and structure are not described herein. Set up two sets of broken bag subassembly that turn to opposite and improve broken bag efficiency, increase opening quantity simultaneously for the material speed of unloading.

Further, as shown in fig. 6 to 8, the feeding device further comprises a bag guiding assembly 12, the bag guiding assembly 12 includes an impeller 13, a third connecting shaft 14 and a wind guiding housing 15, the second connecting shaft 10 is of a hollow structure, the second connecting shaft 10 is coaxially and rotatably sleeved outside the third connecting shaft 14, connecting ends of the third connecting shaft 14 respectively extend out of the second connecting shaft 10, one end of the third connecting shaft 14 is provided with a driven wheel 16, the impeller 13 is arranged at the other end of the third connecting shaft 14, the wind guiding housing 15 is arranged outside the impeller 13, and the wind guiding housing 15 is connected with the feeding bin 4 through a connecting rod;

the top of the bin 2 is provided with a waste bag collecting box 17, the side surface of the waste bag collecting box 17 is provided with a bag inlet, and the bag inlet is opposite to the air guide opening of the air guide shell 15.

The output shaft of the driving mechanism 7 is provided with a driving wheel, and the third connecting shaft 14 is connected with the driven wheel 16, the driving wheel and a transmission belt (belt or chain). Wherein the ratio of the diameter of the drive wheel to the driven wheel 16 is 5:1 or 6:1, the driving wheel is arranged to rotate for one circle, the driven wheel 16 rotates for 5 or 6 circles, and therefore the impeller 13 on the third connecting shaft 14 is enabled to generate sufficient wind.

When the driving mechanism 7 drives the bag breaking piece 6 and the bag cleaning turntable 5 to move, the third connecting shaft 14 is driven to move simultaneously, and the impellers 13 on the third connecting shaft 14 move synchronously, so that wind is generated. The wind generated by the impeller 13 is guided by the wind guide housing 15 and then output directionally. When the bag claw 11 automatically drops towards the material bag on the bag claw 11, the material bag is blown down into the waste bag collecting box 17 to be collected under the action of directional wind, and then the problem that the material bag flies in disorder or falls back to the feeding bin 4 again when airflow exists is avoided.
