A baffle plate 111 is provided on the feeding box 101. The collection assembly includes a collection box 112 and a partitioning member. The partitioning member includes a first partition 113 and a second partition 114. Through the foregoing solution, in the process of discharging materials after injection molding of particles, the particles have different sizes. The device collects the particles uniformly, resulting in the need to separately screen the particles subsequently, increasing the working steps and reducing the efficiency. It can be understood that the foregoing solution can be used to facilitate the screening of particles in the process of discharging materials after injection molding of particles, so that the particles can be collected according to their different sizes, improving the working efficiency. It can also be used to at least screen the raw materials into three different sizes.

[0022] For this specific embodiment, the feed hopper 102 is fixedly connected to the feed box 101 and is located on one side of the feed box 101. The observation window 103 is fixedly connected to the feed box 101 and is located on one side of the feed box 101. The screen 104 is arranged on the feed box 101. The feed hopper 102 is fixed to the upper end of the feed box 101, and the feed hopper 102 is used for feeding. The observation window 103 is arranged on the right outer surface of the feed box 101 for observing the internal situation of the feed box 101. The screen 104 is also arranged inside the feed box 101 to filter out impurities larger than the raw materials, rather than filtering dust. The above are all prior arts.

[0023] Among them, the first sieve plate 105 is fixedly connected to the feeding box 101 and is located on one side of the feeding box 101. The second sieve plate 106 is fixedly connected to the first sieve plate 105 and is located on one side of the first sieve plate 105. The third sieve plate 107 is fixedly connected to the second sieve plate 106 and is located on one side of the second sieve plate 106. The collecting assembly is arranged on the feeding box 101. The sizes of the first through hole 108, the second through hole 109, and the third through hole 110 increase in sequence. The first sieve plate 105, the second sieve plate 106, and the third sieve plate 107 are spliced and fixed together in sequence. The first sieve plate 105 is located inside the feeding box 101. The length of the first sieve plate 105 is adapted to the length of the screen 104. The first sieve plate 105 is located directly below the screen 104. The first sieve plate 105, the second sieve plate 106, and the third sieve plate 107 are in a state of inclining to the right. The raw materials fall onto the first sieve plate 105 through the screen 104. The first sieve plate 105 conducts a preliminary screening on the raw materials. The raw materials with sizes larger than the first through hole 108 continue to roll to the right and are screened by the second through hole 109 on the second sieve plate 106. Similarly, the third through hole 110 on the third sieve plate 107 conducts a final screening on the raw materials, so that the raw materials are at least screened into three different sizes. The collecting assembly is arranged inside the feeding box 101. The collecting assembly is located below the first sieve plate 105, the second sieve plate 106, and the third sieve plate 107, so that raw materials of at least three different sizes can be collected, and the operation is simple. During the discharging process after the particles are injection-molded, the raw materials fall onto the first sieve plate 105 through the screen 104. The first sieve plate 105 conducts a preliminary screening on the raw materials. The raw materials with sizes larger than the first through hole 108 continue to roll to the right and are screened by the second through hole 109 on the second sieve plate 106. Similarly, the third through hole 110 on the third sieve plate 107 conducts a final screening on the raw materials, so that the raw materials are at least screened into three different sizes, and the raw materials can be collected according to particles of different sizes, improving the work efficiency.

[0024] Secondly, the baffle 111 is fixedly connected to the feeding box 101 and is fixedly connected to the third sieve plate 107. The number of the baffles 111 is two. The two baffles 111 are respectively fixed on both sides of the inner cavity of the feeding box 101, and the baffles 111 are respectively located on both sides of the first sieve plate 105, the second sieve plate 106, and the third sieve plate 107, so that when the first sieve plate 105, the second sieve plate 106, and the third sieve plate 107 conduct screening on the raw materials, the raw materials will not fall from both sides under the blocking action of the baffles 111.

[0025] Meanwhile, the collection box 112 is detachably connected to the feeding box 101 and is located on one side of the feeding box 101; the first partition plate 113 is fixedly connected to the collection box 112 and is located on one side of the collection box 112; the second partition plate 114 is fixedly connected to the collection box 112 and is located on one side of the collection box 112. The collection box 112 is of a box structure and is placed inside the feeding box 101. The first partition plate 113 and the second partition plate 114 are fixedly arranged inside the collection box 112 in sequence. The first partition plate 113 and the second partition plate 114 divide the interior of the collection box 112 into a first accommodation groove, a second accommodation groove and a third accommodation groove in sequence. The positions of the first accommodation groove, the second accommodation groove and the third accommodation groove correspond to the positions of the first sieve plate 105, the second sieve plate 106 and the third sieve plate 107 respectively, so that after the first sieve plate 105, the second sieve plate 106 and the third sieve plate 107 screen the raw materials, raw materials of different sizes can enter the collection box 112 for collection, improving the working efficiency.

[0026] When using an injection molding automatic feeding device of this embodiment, during the discharging process after injection molding of the particles, the raw materials fall onto the first sieve plate 105 through the screen mesh 104. The first sieve plate 105 conducts a preliminary screening on the raw materials. The raw materials with sizes larger than the first through hole 108 continue to roll to the right and are screened by the second through hole 109 on the second sieve plate 106. Similarly, the third through hole 110 on the third sieve plate 107 conducts a final screening on the raw materials, so that the raw materials are at least screened into three different sizes, enabling collection according to particles of different sizes and improving the working efficiency.
