Description

Technical Field

[0001] The utility model belongs to the technical field of mixing and feeding systems, and in particular relates to a mixing and feeding mechanism for masterbatch main materials. Background Art

[0002] Existing masterbatch mixing usually uses a mixer to mix the masterbatch. This device is widely used in the field of chemical fiber production. Its principle includes the principle of screw movement. While the screw is rotating, due to its special spiral shape, it generates shearing, extrusion and other forces with the material in the mixing chamber, causing the material to continuously deform, thereby achieving a mixing effect. Alternatively, the principle of heat conduction is adopted. The screw masterbatch mixer usually heats the mixing chamber. Through the principle of heat conduction, the material reaches a certain temperature during the mixing process, thereby improving the mixing effect and the fluidity of the material. However, the above mixing methods cannot achieve uniform mixing of masterbatches in the feeding stage, thereby prolonging the material mixing time.

[0003] In order to solve the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a masterbatch feeding device [202210359014.7], in which a plurality of storage boxes are arranged side by side above the mixing box to store masterbatches of different colors; a feeding barrel is provided at the bottom of the storage box, and a discharging plate and a weighing platform for weighing the weight of the masterbatches discharged from the discharging plate are provided in the discharging cavity of the feeding barrel. The discharging plate is driven by a servo motor installed on the feeding barrel, and the masterbatches on the weighing platform are pushed out by an electric push rod arranged in the feeding barrel; a stirring roller group is provided in the mixing box to stir the plastic raw materials and masterbatches; a camera module for real-time shooting of the finished plastic product is also provided above the mixing box, and the feeding control system compares the color of the captured picture with the preset picture. When the color is consistent, the corresponding masterbatch dosage ratio is recorded as the basis for subsequent feeding.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1-5 As shown, a masterbatch main material mixing and discharging mechanism comprises a vertically arranged discharging barrel 1, and a plurality of independent feeding barrels 2 are connected to the upper end of the discharging barrel 1, and each feeding barrel 2 is respectively connected to a feeding pipeline. A plurality of stacked discharging plates 3 are arranged inside the discharging barrel 1 to receive the masterbatch, and a pushing assembly 4 extending to the edge is installed in the middle of the discharging plate 3. Under the action of the pushing assembly 4, the masterbatch is pushed from the middle of the discharging plate 3 to the edge and falls. A collecting funnel 5 is respectively installed below the discharging plate 3 to collect the discharged masterbatch to the middle of the discharging plate 3 below for multiple mixing, and a feeding assembly 6 is installed at the bottom of the discharging barrel 1 to guide the mixed masterbatch out for subsequent melting treatment.

[0025] Specifically, similar to the conventional feeding structure, the feeding barrel 2 in the present application is arranged at an angle and is connected to a feeding funnel 21. A locking buckle 22 is installed at the edge of the feeding funnel 21 for connecting and fixing an external feeding pipeline. A feeding observation port 23 is installed on one side of the feeding barrel 2, which is usually closed by a transparent cover. The operator can directly observe the internal feeding status through the feeding observation port 23.

[0026] In order to ensure that the blanking plate 3 can vibrate slightly to speed up the blanking, a support frame 7 is installed between the blanking plate 3 and the blanking barrel 1, a damping element 71 is installed between the lower end of the edge of the blanking plate 3 and the upper end of the support frame 7, and an electromagnetic vibrator 72 is installed at the lower end of the blanking plate 3. The electromagnetic vibrator 72 makes the blanking plate 3 vibrate at a high frequency.

[0027] Furthermore, in the present application, the pusher assembly 4 adopts a rotary propulsion method, which includes a driving rod 41 rotatably mounted at the center of the blanking plate 3, a driving motor 42 connected to the driving rod 41 is mounted at the upper end of the unloading barrel 1, the driving rod 41 is connected to a pusher rack 43 located at the upper end of the blanking plate 3, the pusher rack 43 has a plurality of pusher bars 44 arranged symmetrically and opposite to the upper end of the blanking plate 3, the pusher bars 44 are arc-shaped and have scraper bars 45 that fit the upper end of the blanking plate 3. The driving motor 42 drives the driving rod 41 and the scraper bars 45 to rotate, and the scraper bars 45 push the masterbatch located in the middle of the blanking plate 3 to the edge during the rotation process.

[0028] Furthermore, the diameter of the inlet at the upper end of the material collecting funnel 5 is larger than the diameter of the blanking plate 3, the outlet at the lower end of the material collecting funnel 5 is opposite to the center of the blanking plate 3, and a spiral guide rib 51 is arranged inside the material collecting funnel 5. When the masterbatch falls into the material collecting funnel 5, the guide rib 51 slides down in a spiral shape, and the masterbatch is mixed twice during the sliding process.

[0029] In addition, the feeding assembly 6 adopts a spiral feeding method, which includes a feeding trough 61 installed at the bottom of the lower barrel 1, a feeding barrel 62 is opened on one side of the feeding trough 61, a feeding screw 63 extending into the feeding trough 61 is rotatably installed inside the feeding barrel 62, and the feeding screw 63 is connected to the feeding motor 64. The mixed masterbatch is initially extruded through the feeding barrel 62 and the feeding screw 63, and then it is convenient to introduce it into the subsequent hot melt system.

[0030] At the same time, in order to maintain the vertical state of the material discharge barrel 1, a vertically arranged support rod 8 is connected to the outer side of the feeding screw 63, and a support frame 81 for assembling the material discharge plate 3 and the material collection funnel 5 is arranged in the middle of the support rod 8. The support rod 8 and the support frame 81 provide support for the material discharge barrel 1 while ensuring that the material collection funnel 5 is relatively fixed.

[0031] It can be seen that a sieve net 9 opposite to the feed barrel 2 is provided at the upper end of the discharge barrel 1, the sieve net 9 is movably connected to a vibration component, and a discharge port 91 opposite to the sieve net 9 is opened on the side of the discharge barrel 1. The sieve net 9 sieves the masterbatch, and the vibration component prevents the masterbatch from agglomerating during the screening process.

[0032] Obviously, the vibration component uses ultrasonic vibration to accelerate the screening of masterbatch, which includes a pulling rod 92 connected to the screen mesh 9, with an elastic reset member built in the pulling rod 92, and a transducer 93 is installed between the screen mesh 9 and the lower barrel 1. The vibration of the transducer 93 is directly transmitted to the screen mesh 9, and the masterbatch with too large particles jumps to the edge of the screen mesh 9 during the vibration process and is discharged from the discharge port 91.

[0033] Preferably, in addition to the conventional damping structure for sound absorption and vibration reduction, the outer side of the unloading barrel 1 is coated with a sound insulation layer 94 to further improve its sound insulation effect, thereby reducing the working noise of the unloading mechanism.

[0034] In summary, the principle of this embodiment is that the blanking plates 3 are stacked in the blanking barrel 1, and a collecting funnel 5 is installed under each blanking plate 3 to concentrate the discharged master particles. The pushing component 4 pushes the master particles on the blanking plate 3 into the collecting funnel 5. After multiple dispersions and concentrations, the master particles are evenly mixed and are extruded, shaped and exported by the feeding component 6.
