Description

Technical Field

[0001] The utility model relates to the field of production technology, in particular to a masterbatch mixer. Background Art

[0002] The masterbatch mixer plays a crucial role in the plastic processing industry. Its main function is to evenly disperse masterbatch (plastic particles containing high concentrations of additives or pigments) into the base resin to ensure color, performance, and quality consistency of the final product.

[0003] During the daily operation of the masterbatch mixer, there is a technical problem, which is the cleaning problem of the equipment. Masterbatch, especially those containing high concentrations of pigments or additives, often leave residues on the inner wall of the machine, mixing blades, and corners of complex structures during the mixing process. These residues become increasingly difficult to remove over time, partly because they may contain certain components, such as pigments or additives, which may solidify or become extremely viscous under the action of heat and pressure and adhere tightly to the metal surface. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a masterbatch mixer, which solves the technical problem that the existing masterbatch mixer is inconvenient to clean.

[0005] A masterbatch mixer according to an embodiment of the utility model includes a mixing barrel and a mixing device arranged on the upper side of the mixing barrel. One side of the bottom of the mixing barrel is provided with a discharge port, and an opening and closing door is arranged at the discharge port. The inner wall of the mixing barrel is provided with heating wires.

[0006] A wear-resistant protection bag is arranged inside the mixing barrel. The wear-resistant protection bag is detachably installed at the bottom edge and the side of the mixing barrel. The bottom of the wear-resistant protection bag is provided with a discharge ring, and the discharge ring is detachably installed at the discharge port.

[0007] The technical principle of the utility model is as follows: Before heating and mixing, first fix a wear-resistant protection bag on the inner wall of the mixing barrel, then add raw materials, heat through the heating wires, and mix with the mixing device. After the raw materials are heated and mixed, open the opening and closing door, and pierce the wear-resistant protection bag at the discharge ring with a sharp object to let the raw materials flow out from the discharge port. When cleaning, directly remove the wear-resistant protection bag and discard it, and the cleaning of the mixing barrel can be quickly completed.

[0008] Specifically, due to the existence of the wear-resistant protection bag, the opening and closing door does not need to be sealed, and only needs to block the outflow of raw materials.

[0009] Compared with the prior art, the utility model has the following beneficial effects: by installing the wear-resistant protection bag inside the mixing barrel and cooperating with the discharge port and the opening and closing door, it solves the technical problem of inconvenient cleaning existing in the existing masterbatch mixer.

[0010] Further, the mixing device includes a mixing motor and a mixing paddle, and a heat shrinkable protective layer is wrapped on the mixing paddle.

[0011] Further, cutting grooves are provided on the mixing paddle.

[0012] During cleaning, directly use a knife to slide along the cutting groove to cut open the heat shrinkable protective layer; during installation, put the heat shrinkable protective layer on the mixing paddle, and then use a hot air gun to heat it to make it closely adhere to the mixing paddle.

[0013] Further, one side of the opening and closing door is hinged to the mixing barrel, and a buckle structure is provided on the other side of the opening and closing door to connect with the mixing barrel.

[0014] Further, fluff stickers are provided on the outer side of the top of the wear-resistant protection bag, and fluff stickers are provided on the bottom of the wear-resistant protection bag and the outer side of the heat shrinkable protective layer. Burr stickers are provided on the inner edges of the top and bottom of the inner side of the mixing barrel and the inner side of the discharge port, and the burr stickers hook the fluff stickers to fix.

[0015] Further, convex columns are evenly distributed on the outer side of the top of the mixing barrel. An elastic rope loop is provided on the top of the wear-resistant protection bag, and notches are evenly distributed on the top of the wear-resistant protection bag. The elastic rope loop passes through the notches and is fixed on the convex columns.

[0016] Further, the wear-resistant protection bag is made of polytetrafluoroethylene.

[0017] Further, the discharge ring is made of rubber. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0024] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.

[0025] As Figures 1-3 shown, the masterbatch mixer includes a mixing barrel 100 and a mixing device 200 arranged on the upper side of the mixing barrel 100 for mixing. One side of the bottom of the mixing barrel 100 is provided with a discharge port 110 for discharging materials. An opening and closing door 111 is arranged at the discharge port 110. The inner wall of the mixing barrel 100 is provided with a heating wire 120 for heating raw materials;

[0026] Specifically, a wear-resistant protective bag 300 is arranged inside the mixing barrel 100. The wear-resistant protective bag 300 is detachably installed on the bottom edge and the side surface of the mixing barrel 100. A discharge ring 310 is arranged at the bottom of the wear-resistant protective bag 300. The discharge ring 310 is detachably installed at the discharge port 110, so that the wear-resistant protective bag 300 is stably fixed on the inner wall of the mixing barrel 100, avoiding the displacement of the wear-resistant protective bag 300 when the mixing device 200 works. The wear-resistant protective bag 300 is made of polytetrafluoroethylene and can work within a temperature of 300 °C. The discharge ring 310 is made of rubber to avoid the problem that the entire wear-resistant protective bag 300 is torn after the discharge port 110 of the wear-resistant protective bag 300 is punctured.

[0027] As Figure 1 、 4 shown, the mixing device 200 includes a mixing motor 210 and a mixing paddle 220. A heat-shrinkable protective layer 221 is wrapped on the mixing paddle 220. A cutting groove 222 is arranged on the mixing paddle 220 to facilitate the peeling of the heat-shrinkable protective layer 221 for cleaning.

[0028] As Figures 2-3 shown, one side of the opening and closing door 111 is hinged to the mixing barrel 100 by a hinge. The other side of the opening and closing door 111 is provided with a buckle structure to connect with the mixing barrel 100. When it needs to be opened, the buckle structure is untied. When it needs to be closed, the opening and closing door 111 is connected to the mixing barrel 100 through the buckle structure.

[0029] As Figure 5As shown, a fluff sticker 320 is adhesively fixed to the outer side of the top of the wear-resistant protection bag 300, and fluff stickers 320 are adhesively fixed to both the bottom of the wear-resistant protection bag 300 and the outer side of the heat-shrinkable protection layer 221. Fluff stickers 130 are adhesively fixed to the inner edges of the top and bottom of the side of the stirring barrel 100 and the inner side of the discharge port 110. The fluff stickers 130 hook the fluff stickers 320 to be fixed, forming a Velcro connection relationship, which is convenient for fixing and disassembling.

[0030] As Figure 5 shown, evenly distributed protruding columns 140 are welded and fixed to the outer side of the top of the stirring barrel 100. An elastic rope loop 330 is provided at the top of the wear-resistant protection bag 300, and notches 331 are evenly distributed at the top of the wear-resistant protection bag 300. The elastic rope loop 330 passes through the notches 331 and is fixed to the protruding columns 140, playing a role in fixing the wear-resistant protection bag 300.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
