Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch feeders, in particular to a masterbatch feeder with a fast-changing hopper. Background Art

[0002] Masterbatch is a new type of colorant specially used for polymer materials, also known as pigment preparation. Masterbatch is mainly used in plastics. It is composed of three basic elements: pigment, carrier and additive. It is a pigment concentrate made by evenly loading an extraordinary amount of pigment into the resin, which can achieve the coloring of the designed pigment concentration.

[0003] The masterbatch feeders on the market have the following problems when in use: the existing hopper is connected to the feed port by welding. When the color needs to be changed, the hopper needs to be cleaned and then the corresponding masterbatch needs to be added. However, cleaning is very troublesome, especially when switching from red to white, which takes a long time.

[0004] If the feed hopper can be switched directly, the intermediate downtime can be greatly saved. Based on this, this case was born. Utility Model Content

[0014] (3) Beneficial effects

[0015] The utility model provides a masterbatch feeder with a quick hopper replacement. It has the following beneficial effects:

[0016] 1. This masterbatch feeder with a quick-change hopper requires only a press of the push rod to disassemble the hopper. As the hopper is pulled upward, the inner wall of the fixing groove forces the positioning ball into the guide groove, allowing for unrestricted insertion and removal. During the hopper installation phase, simply press the push rod. Once the sleeve is fully inserted into the fixing groove, release the push rod. The push rod then rises, and the lower section of the guide groove pushes the positioning ball into the fixing hole, creating a stop. This allows for rapid hopper replacement, minimizes downtime, and significantly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention provides a masterbatch feeder with a quick hopper replacement. Figure 1-4 As shown, it includes a feed box 1 connected to the extruder and a feed hopper 2. The bottom of the feed hopper 2 is provided with a flat support plate 3. The top of the feed box 1 is provided with a feed port 5. The bottom discharge port of the feed hopper 2 is provided with an inner sleeve 7 with a smaller outer diameter than the feed port 5 and an outer sleeve 6 with a larger inner diameter than the feed port 5. The combination of the outer sleeve 6 and the inner sleeve 7 can prevent the discharge of the feed hopper 2 from overflowing from the feed port 5, improving the sealing performance. The discharge port of the feed hopper 2 is provided with a solenoid valve. The discharge amount of the discharge port is controlled by the solenoid valve.

[0023] The support plate 3 and the feed box 1 are detachably connected via a fixing mechanism 4 .

[0024] Handles 10 are provided on both sides of the support plate 3 for holding the feed hopper 2 when it is disassembled.

[0025] like Figure 2 As shown, in order to facilitate the alignment of the discharge port of the feed hopper 2 with the feed port 5, a plurality of positioning rods 8 are provided on the top of the feed box 1. The support plate 3 is provided with positioning holes 9 corresponding to the plurality of positioning rods 8. When the positioning holes 9 are fitted over the positioning rods 8, the outer sleeve 6 and the inner sleeve 7 fit neatly over the feed port 5. A total of four positioning rods 8 are provided, and the four positioning rods 8 are distributed in a rectangular shape on the support plate 4.

[0026] There are two sets of fixing mechanisms 4 , which are respectively distributed on the support plate 3 and located on both sides of the feed hopper 2 .

[0027] like Figure 3-4As shown, the fixing mechanism 4 includes a fixing groove 41 vertically arranged on the feed box 1, a sleeve 42 vertically arranged on the support plate 3, a pressing column 43, a spring 44, several sets of positioning balls 45, and a guide groove 47. The sleeve 42 can be vertically inserted into the fixing groove 41, and the pressing column 43 is vertically slidably adapted on the sleeve 42, and the bottom is connected to the bottom of the sleeve 42 via the spring 44. A fixing hole 48 is formed on the inner wall of the fixing groove 41, and a through hole 46 corresponding to the fixing hole 48 is formed on the outer wall of the sleeve 42. When the sleeve 42 is fully inserted vertically into the fixing groove 41, the through hole 46 corresponds to the fixing hole 48. The guide groove 47 is opened in the middle section of the pressing column 43 and is trapezoidal in shape. The diameter of the section of the pressing column 43 located below the guide groove 47 is smaller than the diameter of the section located above the guide groove 47. The positioning ball 45 is located between the pressing column 43 and the sleeve 42 and below the guide groove 47. The diameter of the through hole 46 is slightly smaller than the diameter of the positioning ball 45. At least one-third of the positioning ball 45 can extend out of the through hole 46. The specific diameter ratio of the positioning ball 45 to the through hole 46 is 1 to 0.8.

[0028] Under normal conditions, the fixing mechanism 4 Figure 3 As shown, the positioning ball 45 is located below the guide groove 47 , and the pressing column 43 is located below the guide groove 47 to squeeze the positioning ball 45 out of the through hole 46 .

[0029] When installing or removing the feed hopper 2, the pressing post 43 is pressed downward, aligning the guide groove 47 with the through hole 46. Regardless of whether the sleeve 42 is inserted into or removed from the fixing groove 41, the inner wall of the fixing groove 41 can squeeze the positioning ball 45 into the guide groove 47, allowing for unrestricted insertion and removal. During the installation phase, after the sleeve 42 is fully inserted into the fixing groove 41, the pressing post 43 is released, and the pressing post 43 rises. The lower section of the pressing post 43 located below the guide groove 47 squeezes the positioning ball 45 into the fixing hole 48, forming a stop.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
