[0036] EMBODIMENT

[0037] Please refer to Figure 1As shown, the embodiment provides a granulator, which comprises a material tank 10, a discharging mechanism 20 and a circulating pipe 30, the discharging mechanism 20 comprises a suction tank 201 and a suction power unit 202 arranged on the suction tank 201, the inlet of the suction tank 201 is communicated to the material tank 10, the suction tank 201 is provided with an outlet pipe 2011, and the outlet pipe 2011 is provided with a rubbing charge generating member 2012; the outlet pipe 2011 is communicated to one end of the circulating pipe 30; the middle part of the circulating pipe 30 is provided with a discharging pipe 301 and a blowing pipe 302, and the discharging pipe 301 and the blowing pipe are linearly arranged on the two side walls of the circulating pipe 30.

[0038] In the embodiment, the granulator can be applied to the filling work of foaming material, and the suction power unit (such as a suction fan) is used to suck and transport the foaming particles in the material tank 10, and finally output the filling through the discharging pipe 301, so as to form the effect of automatic equipment filling. In order to facilitate the understanding of the following description, the transportation of foaming particles is taken as an example.

[0039] In use, the granulator is started, so that the suction power unit 202 sucks and transports the foaming particles in the material tank 10, and rubs the foaming particles through the rubbing charge generating member 2012 on the outlet pipe 2011 to generate static electricity, so that the foaming particles carry the same charge, and the mutual repulsion between the foaming particles is achieved. Thus, when the foaming particles are output into the circulating pipe 30, the foaming particles are blown out through the blowing pipe 302 towards the discharging pipe 301 at the position of the discharging pipe 301, and the foaming particles are blown out through the discharging pipe 301, so as to realize the purpose of high efficiency and smooth filling of the foaming particles, and good practicability is achieved.

[0040] Specifically, the rubbing charge generating member 2012 can be artificial fibers such as nylon or wool; thus, when the foaming particles rub against the nylon or wool, the same static electricity is carried, so that each foaming particle carries static electricity for output, and the mutual repulsion between the foaming particles can effectively avoid the foaming particles from being blocked in the discharging pipe 301, and the output efficiency and smoothness are improved.

[0041] Further, as shown in the drawings, Figure 1 and Figure 2As shown, the friction member 2012 in this embodiment can be designed as a brush structure 2013, and the bristle material of the brush structure 2013 is not adjacent to the foamed particles in the triboelectric sequence. The brush structure 2013 is fixed on the outlet pipe 2011, so that each particle can be rubbed with the friction member 2012, and the friction resistance is small, which can be output through the airflow, and the efficiency of the foamed particle conveying can be ensured.

[0042] Specifically, according to the difficulty of electron gain and loss, different substances can be arranged in an electrostatic sequence table by experimental method. When any two substances in the sequence are in close contact or rubbed, the former is positively charged and the latter is negatively charged. The farther apart the positions of the two substances in the sequence, the more significant the charge when they are in close contact or rubbed. According to Hu Jiyong, editor-in-chief of Textile Sensitive Materials and Sensors, 2019 edition, page 266, the triboelectric sequence of some common materials can be seen in Table 1. Therefore, based on the material of the foamed particles, materials adjacent to or far away from them in the sequence table can be selected as the material of the friction member 2012.

[0043] Table 1: Triboelectric sequence of common materials

[0044]

[0045]

[0046] Further, the number of outlet pipes 2011 can be one or more. When the outlet pipes are multiple, the same or different materials of the friction member 2012 can be arranged in different outlet pipes 2011, for example, the foamed particles are thermoplastic polyurethane foamed material, and the bristle material of the brush structure 2013 is wool or silk or rubber or artificial fiber or polystyrene or polyethylene. As a more specific example, referring to Figure 1 As shown, the outlet pipe 2011 can be two, one of which is installed with artificial fiber (such as nylon), and the other is installed with wool, so that the amount of electricity carried by the foamed particles in the two outlet pipes 2011 is different, so that the conveying can be more intensive during conveying, and the conveying efficiency can be improved. The setting of multiple outlet pipes makes the charging effect of the foamed particles less affected by the state of a single friction material, which is more conducive to the stability of the overall charging.

[0047] As Figure 1As shown, the inner wall of the end section of the circulation pipe 30 in the embodiment is provided with an electrostatic neutralizer 303, which is used to neutralize or eliminate the charge generated by the friction between the foamed particles and the friction element. The electrostatic neutralizer 303 can be a brush structure made of stainless steel, which can attract and remove the static electricity on the foamed particles. In this way, for the recycled foamed particles, the static electricity can be avoided, which can cause the foamed particles to scatter easily and not be easy to use directly for filling, etc. By eliminating static electricity, the convenience and practicality of use can be improved.

[0048] Further, in the embodiment, the other end of the circulation pipe 30 is arranged on the material box 10, so that the foamed particles with eliminated static electricity can be reflowed to the material box 10 to form a circulation, without the need for additional recycling treatment, which has good practicality and improves the production efficiency.

[0049] In another embodiment, by independently arranging a recycling box in communication with the circulation pipe 30, the foamed particles are recycled, and then the material box 10 is supplemented with filling material at a certain time. The number of recycled foamed particles can also be used to know the value of the discharge amount of the foamed particles, so as to adjust the air speed of the blowing pipe 302 to improve the practicality.

[0050] As shown, Figure 1 In the embodiment, the air inlet end of the blowing pipe 302 is provided with an air pump 304, and the air pump 304 is provided with a manually opened or stopped electric control switch 305, that is, the electric control switch 305 is installed on the power line of the air pump 304. The opening or stopping of the air pump 304 is realized by connecting or disconnecting the power line, so as to achieve the control purpose of the air pump 304.

[0051] As shown, Figure 1 In the embodiment, the connection between the discharge pipe 301 and the circulation pipe 30 is provided with a horn-shaped inlet portion 3011 to form a smooth transition camber surface, which can avoid unnecessary collision of the foamed particles when turning through the blowing pipe 302 for blowing, and improve the flow process of the output.

[0052] Further, as shown, Figure 1 In the embodiment, the inlet of the suction material box 201 is arranged at one end of the material box 10, and the bottom of the material box 10 is provided with an inclined surface 101 inclined toward the inlet direction of the suction material box 201; the other end of the circulation pipe 30 is arranged on the top surface or side surface at the highest point of the inclined surface 101 of the material box 10.

[0053] Specifically, by the design of the inclined surface 101, it is beneficial to concentrate the material in the material box 10 at the outlet end of the material box 10 by self-weight, facilitating the suction and conveying of the discharging mechanism 20. At the same time, the filler entering through the circulating pipe 30 is input to the highest point of the inclined surface 101 of the material box 10, which can avoid the blockage of the outlet of the circulating pipe 30 and improve the practicability.

[0054] As shown in Figure 3 the detector for detecting the material level is arranged in the material box 10, or the observation window 102 for observing the material is arranged on the material box 10. For example, by arranging the GP2D12 type infrared detector, the height of the filler in the material box 10 can be known, so as to judge how much filler is in the material box 10, so as to supplement in time. Alternatively, the filler in the material box 10 is directly observed and judged through the observation window, so as to avoid the situation that the filler in the material box 10 is insufficient, and improve the practicability.

[0055] As shown in Figure 1 the gas flow regulating valve 3021 and the air pressure detector 3022 are arranged on the blowing pipe 302, and the DP-702LH type air pressure detector 3022 is arranged on the blowing pipe 302. By controlling the opening degree of the gas flow regulating valve 3021, the air outlet amount of the blowing pipe 302, that is, the size of the gas flow, is controlled, so as to control the discharging amount. At the same time, the air pressure in the blowing pipe 302 can be known through the air pressure detector 3022, so as to judge whether the blowing pipe 302 has good air tightness; at the same time, the air pressure value in the blowing pipe 302 can be known, so as to adjust as required, and improve the practicability.

[0056] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any change or replacement easily thought of by those skilled in the art within the technical range disclosed by the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
