Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of masterbatch production, and more specifically to a pelletizer feeding device for PBAT biodegradable masterbatch. Background Art
[0002] Masterbatch is a new type of colorant specially used for polymer materials, also known as pigment preparation, mainly used in plastics. It is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading an extraordinary amount of pigment into the resin. The pelletizer cuts the extruded strip material into particles of a certain size to form the prototype of the masterbatch. The masterbatch is then screened and discharged through the feeding device to facilitate subsequent processing and production.
[0003] Based on the above, the inventors found that when the existing masterbatch particles fall from the pelletizer to the feeding device, the landing points are concentrated together, which results in a large number of masterbatch particles being fed through a single feeding trough, seriously affecting the feeding efficiency. Therefore, in view of this, the existing structure is studied and improved, and a pelletizer feeding device for PBAT biodegradable masterbatch is provided, in order to achieve a more practical purpose.

[0026] Example:
[0027] See also Figure 1-4 , a pelletizer feeding device for PBAT biodegradable masterbatch comprises a feeding frame 1, a feeding port 2 is provided at the top of the feeding frame 1, a driving motor 3 is fixedly connected to one end of the feeding port 2, a dust removal mechanism 4 is centrally arranged on one side of the feeding port 2, a plurality of feeding troughs 5 are provided on one side of the feeding frame 1, a group of collecting frames 6 are slidably connected to the bottom of the feeding frame 1, a group of partitions 7 are centrally fixedly connected to the inside of the feeding frame 1, a reciprocating screw 8 is fixedly connected to the output end of the driving motor 3, a slider 9 is sleeved on the outer side of the reciprocating screw 8, a push plate 10 is fixedly connected to the bottom surface of the slider 9, and a plurality of air suction holes 11 are provided on both sides of the push plate 10;
[0028] The dust removal mechanism 4 includes a dust pump 12, the input end of the dust pump 12 is fixedly connected to a bellows 13, and the output end of the dust pump 12 is fixedly connected to a dust collecting box 14, and the bottom of the dust collecting box 14 is slidably connected to a suction plate 15 on one side, in order to absorb dust impurities adhered to the surface of the masterbatch particles during the feeding process.
[0029] See also Figure 1 The feed chute 5 is arranged in an inclined shape, and the diameter below the feed chute 5 is larger than the diameter above the feed chute 5. The masterbatch particles pass through the bottom end of the feed inlet 2 and slide down the feed chute 5. According to the size of the masterbatch particles, they automatically fall when they move to the corresponding diameter position of the feed chute 5.
[0030] See also Figure 2 A plurality of collecting frames 6 and a plurality of partitions 7 are arranged alternately, and the partitions 7 are used to prevent the masterbatch particles from being offset when they fall. Then, the plurality of collecting frames 6 cooperate with each other to collect the masterbatch particles of different sizes.
[0031] See also Figure 3 The reciprocating screw 8 passes through the feed port 2, and the reciprocating screw 8 is movably connected to the feed port 2. The feed port 2 is aligned with the discharge position of the pelletizer. The cut masterbatch particles fall directly into the feed port 2. The drive motor 3 is started to drive the reciprocating screw 8 to rotate, thereby causing the slider 9 to reciprocate.
[0032] See also Figure 3 The push plate 10 is located at the lower part of the feed port 2 and is slidably connected to the feed port 2. The movement of the slider 9 drives the push plate 10 to slide horizontally, pushing the masterbatch particles evenly to different feed troughs 5 to avoid the masterbatch particles from piling up.
[0033] See also Figure 4 The dust pump 12 and the dust collecting box 14 are fixedly connected to the feed port 2. The dust pump 12 transports the dust to the inside of the dust collecting box 14, and the dust falls into the inside of the suction plate 15. After the unloading work is completed, the suction plate 15 can be taken out for cleaning.

At the same time, the bellows 13 is stretched synchronously when the push plate 10 moves.
[0035] When in use: align the feed port 2 with the discharge position of the pelletizer, the cut masterbatch particles fall directly into the feed port 2, start the drive motor 3 to drive the reciprocating screw 8 to rotate, so that the slider 9 moves back and forth, and the movement of the slider 9 drives the push plate 10 to slide horizontally, and the masterbatch particles are evenly pushed to different discharge troughs 5 to avoid the masterbatch particles from piling up together. The masterbatch particles pass through the bottom end of the feed port 2 and slide along the discharge trough 5. According to the size of the masterbatch particles, when they move to the corresponding diameter position of the discharge trough 5, they automatically fall down, and the partition 7 is used to prevent the masterbatch particles from offsetting when falling. After that, multiple collection frames 6 cooperate with each other to collect masterbatch particles of different sizes, and at the same time start the dust extraction pump 12 to allow the dust on the surface of the masterbatch particles to pass through the suction hole 11 into the bellows 13. When the push plate 10 moves, the bellows 13 is stretched synchronously, and finally the dust is transported to the inside of the dust collecting box 14, and the dust falls into the inside of the pumping plate 15. After the unloading work is completed, the pumping plate 15 can be taken out for cleaning.
