[0026] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application.
[0027] It should be understood that, in the description of the application, the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and do not indicate or imply that the devices or elements indicated must be in a particular orientation, constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application. The terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. That is, the features with "first", "second" can explicitly or implicitly include one or more features. In addition, unless otherwise stated, the meaning of "multiple" is two or more.
[0028] In addition, the technical features involved in different embodiments of the application described below can be combined with each other as long as there is no conflict between them.
[0029] As Figures 1-4 shown, the hair removal device in the long glass fiber reinforced particle of the embodiment of the utility model, including stock bin 1, conveying pipeline 2, collection bin 3, vacuum pump 4 and filter disc 5. The long glass fiber reinforced particle with hair is input into the stock bin 1, the vacuum pump 4 is vacuumized to the collection bin 3, the conveying pipeline 2 forms negative pressure, the hair is inhaled into the conveying pipeline 2 through the filter disc 5, and is finally collected in the collection bin 3.
[0030] The upper and lower ends of the stock bin 1 correspond to the feed inlet 11 and the discharge outlet 12, and the discharge outlet 12 is configured to communicate with the injection molding machine. Among them, the feed inlet 11 is used to input the long glass fiber reinforced particle, and the long glass fiber reinforced particle is mixed with hair.
[0031] The conveying pipe 2 has an input end 21 and an output end 22, the input end 21 is connected to the side wall of the bin 1. The output end 22 is connected to the side wall of the collecting bin 3, the bin 1 is communicated with the collecting bin 3 through the conveying pipe 2. The collecting bin 3 is used for collecting the hairiness.
[0032] The vacuum pump 4 is installed on the side wall of the collecting bin 3, and is used for vacuumizing the collecting bin 3. The hairiness can be sucked from the bin 1 into the conveying pipe 2 through the vacuum pump 4, and finally collected in the collecting bin 3.
[0033] The filter disc 5 is detachably located in the conveying pipe 2 at the input end 21, and the filter disc 5 has a plurality of filter holes 51, the filter holes 51 are configured to separate the long glass fiber reinforced particles and the hairiness, so that the hairiness passes through the conveying pipe 2 into the collecting bin 3. Specifically, the pore size of the filter holes 51 is set to be such that the long glass fiber reinforced particles cannot be sucked away, while the hairiness can be sucked away. Thus, the long glass fiber reinforced particles are prevented from being sucked into the conveying pipe 2. It should be noted that the ratio of the total cross-sectional area of the plurality of filter holes 51 to the cross-sectional area of the conveying pipe 2 is 0.3-0.7. If the ratio is less than 0.3, the total cross-sectional area of the plurality of filter holes 51 is too small, which reduces the separation efficiency of the hairiness. If the ratio is greater than 0.7, the total cross-sectional area of the plurality of filter holes 51 is too large at this time, the passing amount of gas is larger, at this time, the negative pressure in the conveying pipe 2 is lower, which affects the separation speed of the hairiness, and also reduces the separation efficiency.
[0034] As shown in Figure 4 some embodiments, the conveying pipe 2 has a insertion hole 23 on the outer wall, the filter disc 5 includes a disc body 52, the filter holes 51 are arranged on the disc body 52, and the disc body 52 is installed in the conveying pipe 2 through the insertion hole 23. By arranging the insertion hole 23, the disc body 52 is convenient to install and detach, which is beneficial to cleaning and maintaining the disc body 52.
[0035] As shown in Figure 2 and 3 some embodiments, the filter disc 5 further includes a disc cover 53 arranged on the disc body 52, and the disc cover 53 covers the insertion hole 23. The disc body 52 is used for filtering the hairiness, the disc cover 53 can seal the insertion hole 23, can maintain the conveying pipe 2 in a negative pressure state, and the arrangement of the disc cover 53 is convenient for installing and detaching the filter disc 5.
[0036] As shown in Figure 2As shown, in some embodiments, the filter disc 5 further includes a sealing layer 54, which is disposed below the disc cover 53. The sealing layer 54 is used to seal between the disc cover 53 and the outer wall of the conveying pipe 2. Specifically, the sealing layer 54 is made of rubber and is bonded to the disc cover 53. When the vacuum pump 4 is turned on, a negative pressure is formed in the conveying pipe 2, causing the sealing layer 54 below the disc cover 53 to press tightly against the outer wall of the conveying pipe 2. At this time, the insertion hole 23 is sealed, preventing air from entering the conveying pipe 2 from the insertion hole 23 and affecting the negative pressure effect of the conveying pipe.
[0037] In some embodiments, the outer diameter of the disc 52 is equal to the inner diameter of the conveying pipe 2. To prevent fuzz or long glass fiber reinforced particles from leaking from the gap between the disc 52 and the conveying pipe 2, a sealing ring is provided on the outer periphery of the disc 52 to achieve a sealing effect.
[0038] like Figure 3 and 4 As shown, in some embodiments, the width of the cover 53 is greater than the width of the socket 23, and the thickness of the disc body 52 is less than the width of the socket 23. This allows the disc body 52 to be smoothly inserted into the socket 23, while the cover 53 can cover the socket 23 and seal it.
[0039] In some embodiments, the circumferential length of the cover 53 is greater than or equal to the circumferential length of the socket 23. It should be noted that both the circumferential length of the cover 53 and the circumferential length of the socket 23 are arc-shaped, so that the cover 53 can seal the socket 23.
[0040] In some embodiments, the conveying pipe 2 is arranged horizontally or inclined downwards from the input end 21 to the output end 22. This allows the lint in the conveying pipe 2 to be smoothly fed into the collection bin 3 along the conveying pipe 2.
[0041] In some embodiments, the filter holes 51 have at least ten holes, which are arranged in a ring array on the filter disc 5. By providing multiple filter holes 51, the filtration efficiency of the hair can be improved.
[0042] In some embodiments, the vacuum pump 4 and the output end 22 of the delivery pipe 2 are positioned opposite each other on the side wall of the collection chamber 3. This ensures that the vacuum pump 4 will not interfere with the delivery pipe 2 during operation, guaranteeing operational safety.
[0043] like Figure 1 As shown, in some embodiments, the bottom of the collection chamber 3 has a discharge port 31. The feathers in the collection chamber 3 can be discharged through the discharge port 31.
[0044] In some embodiments, a valve is installed in each of the feeding port 11, the discharging port 12 and the discharging port 31. By setting the valve, the opening or closing of the feeding port 11 and the discharging port 12 of the material bin 1 can be controlled, and the opening or closing of the discharging port 31 of the collecting bin 3 can be controlled.
[0045] The above merely describes the preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
