Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch processing and manufacturing, in particular to a material changing device of a masterbatch feeder. Background Art

[0002] Masterbatch is a plastic colorant made by well-dispersing a high proportion of pigments or additives with thermoplastic resins. The selected resin has good wetting and dispersing effects on the colorant and has good compatibility with the colored material. During processing, a small amount of masterbatch and uncolored resin are mixed through a feeder to achieve the colored resin or product with the designed pigment concentration. In order to effectively control the discharge speed and avoid excessive discharge, the diameter of the discharge port is generally smaller. After long-term use, the masterbatch raw materials are likely to accumulate in the discharge port and discharge pipe, causing blockage, affecting the normal production work and reducing production efficiency.

The bottom surface of the storage bin 5 is fixedly connected to the discharging hopper 31. The knocking plates 312 are symmetrically arranged on both sides of the discharging hopper 31. The surface of the knocking plate 312 is symmetrically slidably connected to the fixing rod 313 with a T-shaped structure, and one end of the fixing rod 313 is connected to the discharging hopper 31. The surface of the fixing rod 313 is sleeved with a spring. There is a spring 314, the surface of the lower hopper 31 is slidably connected to the moving block 310, and the upper surface of the moving block 310 is symmetrically hinged with two sets of connecting rods 311, and one end of the connecting rod 311 is hinged to the knocking plate 312, the bottom surface of the bracket 1 is fixedly connected to the fixing box 35, the interior of the fixing box 35 is rotatably connected to the rotating rod 33, the outer surface of the rotating rod 33 is fixedly sleeved with a cam 37, a push block 39 is provided above the cam 37, and the push block 39 is slidably connected to the interior of the bracket 1, and the side of the fixing box 35 is fixedly connected to the motor 1-36, and the output end of the motor 1-36 is connected to the rotating rod 33. When the device is in use, the masterbatches of different specifications are added to the interior of the storage bin 5 respectively. When feeding, the material is fed into the feeder through the lower hopper 31 and the feeding pipe 32. By driving the storage barrel 2 to rotate, the lower hopper 31 on the different storage bins 5 is aligned with the feeding pipe 32 to realize the replacement of masterbatches of different specifications. During the feeding process, the rotating rod 33 is driven to rotate by starting the motor 1-36, and then the push block 39 is pushed to move back and forth vertically through the cam 37. When the hopper 31 is in the working state, the moving block 310 on the side of the hopper 31 is moved, and the two sets of knocking plates 312 are pushed to slide on the surface of the fixed rod 313 through the connecting rod 311, and the spring 314 is squeezed to contract. When the moving block 310 moves downward, the knocking plates 312 are moved by the elastic force of the spring 314, and the knocking plates 312 are reciprocated to knock and vibrate the side wall of the hopper 31, so that the masterbatch inside the hopper 31 vibrates and falls, thereby avoiding the material from being blocked inside the hopper 31 and affecting the unloading efficiency of the hopper 31. Example 2:

[0027] See also Figure 1-6In this embodiment, a feeding pipe 32 is fixedly connected to one side of the bottom surface of the bracket 1 near the fixed box 35, and the feeding pipe 32 is located below one group of lower hoppers 31. One end of the rotating rod 33 passes through the surface of the fixed box 35 and the feeding pipe 32, and is connected to the conveying auger 34 arranged inside the feeding pipe 32.

The lower hopper 31 is aligned with the feeding tube 32 to realize the replacement of masterbatches of different specifications. The material inside the feeding tube 32 is easily transported by the conveying auger 34. When the storage barrel 2 rotates, the inclined surface of the push block 39 pushes the inclined surface of the moving block 310 to move, so that the push block 39 moves to the bottom of the moving block 310.

A rubber block is fixedly connected to one side of the knocking plate 312 to facilitate knocking on the lower hopper 31 to vibrate it, so that the masterbatch on the inner wall of the lower hopper 31 falls off.

[0028] And by setting the material changing component 4, the surface of the bracket 1 is provided with a material changing component 4, the material changing component 4 includes a transmission rod 41, a second motor 42, a slider 44 and a rotating member 45, the transmission rod 41 is fixedly connected to the center of the inner part of the storage barrel 2, the bottom end of the transmission rod 41 is fixedly connected to the rotating member 45, the side of the bracket 1 surface close to the rotating member 45 is fixedly installed with the second motor 42, the output end of the second motor 42 is fixedly connected to the slider 44 through the connecting rod, the surface of the rotating member 45 is provided with a circular array of movable grooves that match the slider 44, the output end of the slider 44 is fixedly connected to the side of the slider 44 away from the slider 44, and the rotating member 45 is fixedly provided with a fan-shaped block 43. The side of the component 45 is provided with an arc groove in a ring array and matching the sector block 43. The slider 44 is driven by the motor 2 42 to rotate one circle, and the slider 44 will slide in the movable groove on the rotating component 45. Then the rotating component 45 will drive the storage barrel 2 to rotate ninety degrees through the transmission rod 41 to facilitate the alignment of the lower hopper 31 and the feeding pipe 32. When the slider 44 has not slid into the interior of the rotating component 45, the motor 2 42 will drive the sector block 43 to slide in the arc groove on the side of the rotating component 45. The sector block 43 will contact the side wall of the rotating component 45 to limit the rotating component 45, and at the same time ensure that the slider 44 is aligned and slides into the movable groove.

[0029] Through the above steps, by starting the rotation of motor 2 42, the slider 44 can push the rotating part 45 to rotate, thereby driving the storage barrel 2 to rotate, so that different discharge hoppers 31 are moved to the top of the feeding pipe 32, thereby realizing rapid material replacement of different color masterbatches.
