Description

Technical Field

[0001] The utility model relates to the technical field of plastic granulation, in particular to a feeder for plastic particle granulation. Background Art

[0002] The recycling and resource development of waste plastics is a production method that stems from a deep understanding of the environment and resources. It is a way of reducing the pollution of waste plastics to the environment and reducing the waste of resources. Realizing the recycling and resource development of waste plastics is a major event that benefits the country and the people. At present, it mainly relies on the use of plastic granulators to recycle woven bags, container bags or strip plastic lumps and plastic bags. When processing and granulating woven bags, container bags, etc., it is necessary to use a feeder to crush the woven bags, container bags, etc.

[0003] When the existing feeder is in use, a large amount of broken filamentary belts will be wound around the crushing roller when the woven bags and container bags are crushed, which can easily cause the crushing roller to get stuck and rotate unsmoothly. Therefore, more energy is needed to power the crushing roller. In addition, since the woven bags and container bags are light in weight and have a smooth surface, it is difficult for the crushing roller to crush the bags without external force. Usually, the staff manually presses the bags against the crushing roller, but the manual pressing operation is very dangerous and increases the workload of the staff. Utility Model Content

[0004] In order to overcome the above technical problems, the purpose of the utility model is to provide a feeder for plastic particle granulation, which can make the two baffles rotate intermittently by starting the second motor, so that the ends of the bags on the two baffles can be preferentially drawn between the two baffles and between the two crushing rollers in the crushing box, thereby preventing the surface of the bag from contacting the crushing roller, making it difficult for the crushing roller to crush the bag, and does not require the staff to manually press the bag on the crushing roller, thereby avoiding the danger of manual pressing by the staff and reducing the workload of the staff.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A feeder for granulating plastic particles comprises a support frame, a crushing box is fixedly passed through the interior of the support frame, a conveying mechanism is arranged at the bottom end of the crushing box, a cleaning mechanism is arranged inside the crushing box, a shaking mechanism is arranged at the top end of the crushing box, the cleaning mechanism comprises a cleaning component, a blowing component is arranged inside the cleaning component, the cleaning component comprises two pipe shafts respectively located below two crushing rollers inside the crushing box, and the pipe shafts are rotatably connected to two opposite side surfaces inside the crushing box, and a brush with a hollow interior is fixedly connected to the outer wall of the pipe shaft.

[0007] Furthermore, one side of the crushing box is fixedly connected with a U-shaped frame.

[0009] Furthermore, two symmetrical arc-shaped holes are respectively penetrated and opened on both sides of the crushing box along the length direction of the crushing roller. The shaking mechanism includes two symmetrical baffles rotatably connected between the inner sides of both sides of the crushing box. Connecting rods respectively penetrating and sliding through the arc-shaped holes at the corresponding positions are fixedly connected to both ends of the adjacent sides of the two baffles.

[0028] Working principle: When in use, first put the recycled woven bags, container bags, etc. on the two baffles 31, then start the motor 2 37 to make the incomplete gear 38 rotate, when the incomplete gear 38 is meshed with one of the complete gears 2 36, the reel 34 at the corresponding position can rotate, the rotating reel 34 can reel in the two pull ropes 35 at the corresponding position, the reeled pull rope 35 can rotate the baffle 31 at the corresponding position, when the incomplete gear 38 is disengaged from one of the complete gears 2 36, the baffle 31 at the corresponding position is under the action of its own gravity. The incomplete gear 38 is meshed with the other complete gear 2 36 at this time. The rotating incomplete gear 38 can make the other complete gear 2 36 drive the reel 34 at the corresponding position to rotate, so that the baffle 31 at the corresponding position can rotate. The two baffles 31 can be intermittently rotated by starting the motor 2 37, so that the ends of the bags on the two baffles 31 can be preferentially drawn between the two baffles 31 and between the two crushing rollers in the crushing box 11, thereby preventing the surface of the bag from contacting the crushing roller, making it difficult for the crushing roller to crush the bag. When the crushing roller crushes the bag, a lot of broken filamentary belts will be stuck on the crushing roller. At this time, the motor 215 and the air pump 224 can be started.

The two rotating brushes 211 can clean the filamentary belts wrapped around the crushing roller, so as to prevent the filamentary belts from getting stuck on the crushing roller and causing the crushing roller to rotate unsmoothly. , more energy is needed to provide greater power to the crushing roller. After the brush 211 cleans the filamentary belt on the crushing roller, a part of the filamentary belt will remain on the brush 211, and the started air pump 224 can draw external gas into the two hard tubes 221. Since a through hole is provided at the bottom end of the outer wall of the hard tube 221, and multiple air holes are penetrated through the outer walls of the brush 211 and the tube shaft, the gas filled into the hard tube 221 is discharged from the through hole, and the discharged gas can blow the filamentary belt remaining on the brush 211 to the bottom of the crushing box 11.
