Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically to a spiral feeding device for composite premixed materials. Background Technology

[0002] Currently, screw conveyors are often used when adding compound premixes to containers. However, the discharge end of traditional feeding devices is mostly fixed, which causes the material below the discharge end to accumulate too high after entering the container, resulting in uneven distribution of the material. This affects subsequent processing such as packaging to some extent. To address this, we propose a screw feeding device for compound premixes to solve the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a spiral feeding device for composite premixed materials to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spiral feeding device for composite premixed materials, comprising a feeding cylinder, a first discharge pipe fixedly connected to and communicating with the bottom right side of the feeding cylinder, a second discharge pipe connected to the bottom end of the first discharge pipe via a folded pipe, a translation block fixedly installed on the outer side of the second discharge pipe, a first connecting plate welded to the bottom of the feeding cylinder via a vertical rod, a slide rail fixedly installed on the right side of the first connecting plate, a slider slidably connected to the slide rail on the rear side of the translation block via a slider, a second connecting plate fixedly installed at the bottom of the translation block via a telescopic component, and a plurality of feeding rods rotatably connected below the second connecting plate.

[0005] Furthermore, a first motor is fixedly installed on the left side of the first connecting plate, and the output shaft of the first motor passes through to the outside of the first connecting plate and is fixedly connected to a screw. The translation block is threadedly connected to the surface of the screw along the axial direction.

[0006] Furthermore, a second motor is fixedly installed on the top of the second connecting plate, and the output shaft of the second motor passes through to the outside of the second connecting plate and is fixedly connected to a circular plate. The feeding rod is fixedly connected to the outer surface of the circular plate.

[0007] Furthermore, a bearing seat is fixedly installed on one end of the slide rail corresponding to the screw, and one end of the screw passes through the bearing seat and is movably connected to it.

[0008] Furthermore, a hopper is fixedly connected to the left side of the top of the feeding cylinder and communicates with it. A third motor is fixedly installed at the left end of the feeding cylinder. The output shaft of the third motor passes through the inside of the feeding cylinder and is fixedly connected to the surface of the auger plate.

[0009] Furthermore, a sealing ring is fixedly connected to the left side of the inner wall of the feeding cylinder at the position corresponding to the output shaft of the third motor, and the inner side of the sealing ring is in contact with the surface of the output shaft of the third motor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention involves adding the composite premixed material to be fed through a hopper, with the second discharge pipe facing the top of the container. After the third motor is turned on, its output shaft drives the auger blades to rotate, achieving spiral feeding and conveying the material to the first discharge pipe. During this process, the first motor is turned on, causing its output shaft to intermittently drive the screw to rotate in both directions. A translation block threaded onto the screw, limited by a slide rail and slider, can cause the second discharge pipe to move intermittently left and right horizontally, achieving uniform material discharge. Furthermore, based on the height of the material accumulation inside the container, a telescopic component drives the second connecting plate to move vertically. After the second motor is turned on, its output shaft drives the circular plate and multiple feeding rods to rotate slowly, achieving uniform material distribution at the discharge point and further improving the uniformity of material addition. This spiral feeding device for the composite premixed material has a reasonable structural design and is easy to use. Its discharge end adopts a movable design, ensuring uniformity of material distribution and preventing high material accumulation at the discharge end. It also continuously and evenly distributes material on the upper surface of the container, further improving the uniformity of material addition and facilitating subsequent packaging and other processing. It has high practicality. Attached Figure Description

[0018] Please see Figure 1-4 A spiral feeding device for a composite premix includes a feeding cylinder 1. A first discharge pipe 2, which is connected to and communicates with the bottom right side of the feeding cylinder 1, is fixedly connected to the feeding cylinder 1. The bottom end of the first discharge pipe 2 is connected to a second discharge pipe 4 through a folded pipe 3. A translation block 5 is fixedly installed on the outside of the second discharge pipe 4. A first connecting plate 6 is welded to the bottom of the feeding cylinder 1 through a vertical rod. A slide rail 7 is fixedly installed on the right side of the first connecting plate 6. The rear side of the translation block 5 is slidably connected to the slide rail 7 through a slider 8. A second connecting plate 10 is fixedly installed at the bottom of the translation block 5 through a telescopic component 9. The telescopic component 9 can be an electric or pneumatic telescopic column. Several material-distributing rods 11 are rotatably connected to the bottom of the second connecting plate 10. The material-distributing rods 11 can evenly distribute the material from the upper surface of the material piled in the container.

[0019] Specifically, a first motor 12 is fixedly installed on the left side of the first connecting plate 6. The output shaft of the first motor 12 passes through the outside of the first connecting plate 6 and is fixedly connected to a screw 13. The translation block 5 is threadedly connected to the surface of the screw 13 along the axial direction.

[0020] Specifically, a second motor 14 is fixedly installed on the top of the second connecting plate 10, and the output shaft of the second motor 14 passes through to the outside of the second connecting plate 10 and is fixedly connected to a circular plate 15. The feeding rod 11 is fixedly connected to the outer surface of the circular plate 15.

[0021] Specifically, a bearing seat 16 is fixedly installed on one end of the slide rail 7 corresponding to the screw 13. One end of the screw 13 passes through the bearing seat 16 and is movably connected to it. The bearing seat 16 can connect and support the end of the screw 13, thereby improving its smoothness during rotation.

[0022] Specifically, a hopper 17 is fixedly connected to the left side of the top of the feeding cylinder 1 and communicates with it. A third motor 18 is fixedly installed at the left end of the feeding cylinder 1. The output shaft of the third motor 18 passes through the inside of the feeding cylinder 1 and is fixedly connected to the surface of the auger plate 19.

[0023] Specifically, a sealing ring 20 is fixedly connected to the left side of the inner wall of the feeding cylinder 1 at the position corresponding to the output shaft of the third motor 18. The inner side of the sealing ring 20 is in contact with the surface of the output shaft of the third motor 18. The sealing ring 20 can prevent material from seeping out through the gap between the output shaft of the third motor 18 and the feeding cylinder 1.

[0024] The spiral feeding device for this composite premix has a reasonable structural design and is easy to use. Its discharge end adopts a movable design, which ensures the uniformity of the discharge and prevents the material from accumulating at the discharge end. It can also continuously and evenly distribute the material on the upper surface of the container, further improving the uniformity of material addition. This is beneficial to subsequent packaging and other processing, and has high practicality.

[0025] In use, the compound premixed material to be fed is added through the hopper 17, so that the second discharge pipe 4 is directly above the container. After the third motor 18 is turned on, its output shaft drives the auger plate 19 to rotate, realizing spiral feeding and conveying the material to the first discharge pipe 2. During this process, the first motor 12 is turned on, so that its output shaft intermittently drives the screw 13 to rotate in both directions. The translation block 5 threaded on it can drive the second discharge pipe 4 to move horizontally left and right intermittently through the limit of the slide rail 7 and the slider 8, so as to achieve uniform discharge of material. According to the height of the material accumulation in the container, the telescopic part 9 drives the second connecting plate 10 to move vertically. After the second motor 14 is turned on, its output shaft drives the circular plate 15 and multiple feeding rods 11 to rotate slowly, so as to achieve uniform distribution of material at the discharge point and further improve the uniformity of material addition.
