[0018] The present utility model provides a screw feeder with anti-jamming, as Figures 1-3 shown, including a frame 1, a feed hopper 2 and a screw lifting device 5. The feed hopper 2 is fixedly installed on the top surface of the frame 1. A sloping hopper 3 is provided at the bottom of the feed hopper 2. A feed pipe 4 is provided in the middle of the bottom of the sloping hopper 3. The feed inlet at one end of the screw lifting device 5 is communicated with the bottom side of the feed pipe 4. A vertical arrangement dredging mechanism 6 is provided on the top surface of the feed hopper 2, and the end of the dredging mechanism 6 extends into the feed pipe 4. A vibration mechanism 7 is movably installed below the sloping hopper 3 at the bottom of the frame 1.

[0019] During feeding, plastic particle products are poured into the feed hopper 2. Under the action of gravity, the plastic particles move towards the sloping hopper 3 and the feed pipe 4, so that the plastic particles fall into the screw lifting device 5. At this time, the dredging mechanism 6 stirs the granular materials in the feed hopper 2, the sloping hopper 3 and the feed pipe 4, and disperses the materials to avoid blockage of the feed pipe 4 caused by the concentration of materials; at the same time, the vibration mechanism 7 generates vibration to knock on the four sides of the bottom surface of the sloping hopper 3, so that the sloping hopper 3 generates vibration. Under the action of the amplitude and gravity, the materials are shaken and dispersed and move closer to the feed pipe 4 and roll down. The dredging mechanism 6 and the vibration mechanism 7 cooperate with each other to effectively avoid the situation of material blockage.

[0020] As one of the embodiments, the dredging mechanism 6 includes a cross bracket 61, a reduction motor 62, a connecting rod 63 and a stirring rod 64. The cross bracket 61 is detachably installed on the top surface of the feed hopper 2. A reduction motor 62 is installed on the top surface of the middle part of the cross bracket 61. A connecting rod 63 is rotatably installed on the bottom surface of the middle part of the cross bracket 61, and the bottom end of the connecting rod 63 extends to the inner bottom end of the feed pipe 4. A plurality of stirring rods 64 are arranged on the outer surface of the connecting rod 63.

[0021] During feeding, the reduction motor 62 is turned on, and the reduction motor 62 drives the connecting rod 63 to slowly and evenly rotate at the bottom of the cross bracket 61, so that a plurality of stirring rods 64 on the outer surface of the connecting rod 63 stir the surrounding materials and disperse the materials to avoid blockage of the feed pipe 4 caused by the concentration of materials.

[0022] As one of the embodiments, the vibration mechanism 7 includes a support plate 71, a gasket 72, a spring 73, a vibration motor 74, a support rod 75, and a rubber ball 76. The four corners of the support plate 71 are slidably sleeved on the legs of the frame 1. A through hole for the material pipe 4 to pass through is provided in the middle of the support plate 71. A gasket 72 is fixedly installed at the bottom of each leg located at the bottom of the support plate 71. A spring 73 is sleeved between the leg and the support plate 71 and the gasket 72. A vibration motor 74 is fixedly installed on the bottom surface of the support plate 71. Support rods 75 are fixedly installed in the middle of the four sides of the top surface of the support plate 71. A rubber ball 76 is fixedly connected to the top of each support rod 75. The rubber ball 76 contacts the bottom surface of the inclined hopper 3. The four rubber balls 76 respectively correspond to and contact the middle parts of the four sides of the bottom surface of the inclined hopper 3.

[0023] During feeding, the vibration motor 74 is turned on. The vibration motor 74 generates vibrations. Under the action of the spring 73, the support plate 71 shakes, so that the four support rod rubber balls 75 on the top surface of the support plate 71 and the four rubber balls 76 also shake. Further, the rubber balls 76 knock on the four sides of the bottom surface of the inclined hopper 3, causing the inclined hopper 3 to generate an amplitude. Under the action of the amplitude and gravity, the materials are shaken loose and roll towards the material pipe 4.

[0024] As one of the embodiments, the bolt lifting device 5 includes a conveying pipe 51, a spiral blade 52, a rotating motor 53, a discharge pipe 54, and a support rod 55. The conveying pipe 51 is designed at an inclined angle. The bottom end of the conveying pipe 51 is communicated with the material pipe 4. A discharge pipe 54 is provided at the bottom of the other end. A spiral blade 52 is rotatably installed inside the conveying pipe 51. A rotating motor 53 is fixedly installed at the top of the other end of the conveying pipe 51. The output shaft of the rotating motor 53 is fixedly connected to the spiral blade 52. The bottom of the conveying pipe 51 is detachably installed on the support rod 55.

[0025] During feeding, the rotating motor 53 is turned on. The rotating motor 53 drives the spiral blade 52 to rotate inside the conveying pipe 51, so as to spirally lift the materials falling from the material pipe 4. The continuously lifted materials move to the top of the conveying pipe 51 and fall and are discharged from the discharge pipe 54.

[0026] Working principle of the utility model: During feeding, plastic pellet products are poured into the feed box 2. Under the action of gravity, the plastic pellets move towards the inclined hopper 3 and the feed pipe 4. At the same time, the reduction motor 62, the vibration motor 74 and the rotation motor 53 are started. The reduction motor 62 drives the connecting rod 63 to slowly rotate evenly at the bottom of the cross bracket 61, so that several stirring rods 64 on the outer surface of the connecting rod 63 agitate the surrounding materials, disperse the materials, and prevent the feed pipe 4 from being blocked due to the concentration of materials. The vibration motor 74 generates vibration, and under the action of the spring 73, the support plate 71 shakes, so that the four support rod rubber balls 75 on the top surface of the support plate 71 and the four rubber balls 76 also shake. Furthermore, the rubber balls 76 knock on the four sides of the bottom surface of the inclined hopper 3, causing the inclined hopper 3 to generate an amplitude. Under the action of the amplitude and gravity, the materials are shaken and dispersed and roll towards the feed pipe 4. The rotation motor 53 drives the spiral blade 52 to rotate inside the conveying pipe 51, and spirally lifts the materials falling from the feed pipe 4. The continuously lifted materials move to the top of the conveying pipe 51 and fall and are discharged from the discharge pipe 54.
