Description

Technical Field

[0001] The invention relates to the field of granule filling equipment, in particular to a granule filling machine. Background Art

[0002] Nowadays, many fabrics need to be filled with fillers, such as foamed particles. However, there are the following difficulties when filling with foamed particles: First, for the pipes of existing filling equipment, when the size is relatively small, it is easy for the foamed particles to block the discharge port or discharge pipe; second, if the size of the discharge pipe is increased, the volume of the equipment will be increased invisibly, and the filling equipment will not be suitable for some fabrics with small filling channels. Manual filling is time-consuming and labor-intensive, and the product quality is uneven.

[0003] In summary, in order to solve the above problems and at the same time perform filling operations efficiently, the present invention proposes a pelletizing machine to fill the gap in the market. Summary of the invention

[0004] The object of the present invention is to provide a granulator, aiming to improve the problem of easy blockage during foaming and filling in the prior art.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] After adopting the above technical solution, the present invention has the following advantages compared with the background technology:

[0007] 1. The friction between the friction parts and the filler makes the filler carry static electricity, and the fillers with the same charge will have repulsion. In this way, the fillers will not stick together during the conveying process, which will cause the problem of clogging the discharge pipe, forming an efficient and smooth conveying effect, improving production efficiency, and reducing the failure rate.

[0008] 2. Connect the circulation pipe to the material box so that the material box, the discharging mechanism and the circulation pipe form a loop. In this way, a circulation can be formed during the filling operation, and there is no need to perform additional recovery of the filler discharged from the other end of the circulation pipe, thereby improving the efficiency of the equipment operation.

[0009] 3. There is an electrostatic neutralizer at the end of the circulation pipe, which can eliminate the static electricity carried by the filler, so that the filler returning to the material box will not be affected by static electricity and can be smoothly sucked out of the material box again, thereby improving the smoothness and practicality of the operation of the granulator.

[0025] Example

[0026] Please refer to Figure 1-Figure 3 As shown, the present embodiment provides a pelletizing machine, including a feed box 10, a discharging mechanism 20 and a circulation pipe 30, the discharging mechanism 20 includes a suction box 201 and a suction power unit 202 arranged on the suction box 201, the inlet of the suction box 201 is connected to the feed box 10, the suction box 201 is provided with at least one outlet pipe 2011, and the outlet pipe 2011 is provided with a friction member 2012 for generating electric charge by friction; the outlet pipe 2011 is connected and arranged on one end of the circulation pipe 30; the discharging pipe 301 and the blowing pipe 302 are arranged in the middle of the circulation pipe 30, and the discharging pipe 301 and the blowing pipe 302 are arranged on the two side walls of the circulation pipe 30 in a straight line and opposite to each other.

[0027] In this embodiment, the pelletizing machine can be used in the filling operation of the foaming material, and the foaming particles in the feed box 10 are sucked and transported by using the suction force of the suction power unit (such as a suction fan), and finally output and fill them through the discharge pipe 301, thereby forming an automated equipment filling effect. For ease of understanding, the following description takes the transportation of foaming particles as an example.

[0028] When in use, the pelletizing machine is turned on, so that the suction power unit 202 pumps out the foam in the feed box 10, and generates static electricity through friction with the friction piece 2012 on the outlet pipe 2011, so that the foam particles carry the same charge, so that the foam particles will not stick to each other during the output process, that is, there is mutual repulsion between the foam particles. In this way, after the foam particles are output to the circulation pipe 30, when passing through the position of the discharge pipe 301, the blowing pipe 302 is used to blow air toward the discharge pipe 301, and the foam particles are blown out through the discharge pipe 301, and the discharge pipe 301 is docked and filled, so that the foam particles can be quickly transported without blocking at a smaller pipe diameter (for example, at the position of the discharge pipe 301, the circulation pipe 30 or the outlet pipe 2011, the foam particles will not stick to each other and block the pipe), so as to achieve the purpose of efficient and smooth filling of foam particles, and has good practicality.

[0029] Specifically, different substances can be arranged into an electrostatic sequence table by experimental methods according to the difficulty of gaining or losing electrons. When any two substances in the sequence are in close contact or friction, the former is positively charged and the latter is negatively charged; the farther the positions of the two substances in the sequence are, the more significant the charge is when they are in close contact or friction. According to the 2019 edition of "Textile Sensitive Materials and Sensors" edited by Hu Jiyong, page 266, the triboelectric series of some common materials can be seen Figure 4 Therefore, based on the material of the foamed particles, a material that is adjacent to or farther away from the foamed particles in the sequence table may be selected as the material of the friction member 2012 .

[0030] If there are multiple outlet pipes 2011, the friction member 2012 can be made of different materials and installed in different outlet pipes 2011; or, the friction member 2012 can be made of the same material. For example, the foaming particles are thermoplastic polyurethane foaming materials, and the bristles of the brush structure 2013 are made of wool, silk, rubber, artificial fiber, polystyrene or polyethylene.

[0031] In this embodiment, there are more than two outlet pipes, and the coefficient of frictional electrification of the friction piece on one outlet pipe is greater than or equal to the coefficient of frictional electrification of the friction piece on the other outlet pipe. Taking two outlet pipes as an example, one outlet pipe is made of nylon material for the friction piece, and the other outlet pipe is made of wool for the friction piece, so that the foamed particles can carry different amounts of charges through the friction pieces of different materials, forming a more dense and non-sticky conveying effect; at the same time, it can also avoid the situation where the effect of frictional electrification is weakened due to environmental humidity or material wear and other reasons. Different materials can prevent the situation where the same reason affects the effect, and can ensure that one of the effects is reduced, and the static electricity effect generated by the friction of the other is still effective, ensuring the high efficiency of foamed particle conveying.

[0032] That is, when the foamed particles rub against nylon or wool, they can carry the same static electricity, so that each foam particle carries static electricity for transportation, and then the air is blown through the blowing pipe 302 and output through the discharge pipe 301 to fill the foamed particles. The mutually repelling foamed particles can effectively prevent the foamed particles from being blocked in the discharge pipe 301, thereby improving the efficiency and smoothness of the output.

[0033] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, the friction member 2012 can be designed as a brush structure 2013 and fixed on the outlet pipe 2011. The fluffy structure design has good softness and can perform good contact friction, so that each particle can be ensured to rub against the friction member 2012. At the same time, the friction resistance will be smaller and can be output through the airflow to ensure the efficiency of the foaming particle transportation.

[0034] In this embodiment, the outlet pipe is made of conductive material, or a conductive part connected to the friction part is provided inside the outlet pipe; a grounding wire is provided on the outlet pipe or the conductive part. Specifically, the outlet pipe or the conductive part can be made of stainless steel. After being grounded by the grounding wire, the friction part can be prevented from carrying too much static electricity to reduce the friction effect, and the charge of the friction part can be guided out to ensure the friction performance.

[0035] like Figure 1 As shown, in this embodiment, an electrostatic neutralization component 303 is provided in the inner wall of the last section of the circulation pipe 30. The electrostatic neutralization component 303 can be a brush structure made of stainless steel. The static electricity on the foamed particles can be absorbed by the setting of the electrostatic neutralization component 303. In this way, for the recycled foamed particles, the problems caused by static electricity, such as the foamed particles are easy to fly away and are not easy to be directly used for filling again, can be avoided. The convenience and practicality of use can be improved by eliminating static electricity.

[0036] Furthermore, in this embodiment, the other end of the circulation pipe 30 is arranged on the supply box 10, so that the foaming particles with static electricity eliminated can flow back to the supply box 10 to form a cycle without the need for additional recycling treatment, which has good practicality and improves production efficiency.

[0037] In another embodiment, the foaming particles are recovered by independently setting up a recovery box connected to the circulation pipe 30, and then the supply box 10 is replenished with filling materials at regular intervals. The number of recovered foaming particles can also be used to know the numerical value of the discharge amount of the foaming particles, so as to adjust the wind speed of the blowing pipe 302 and improve practicality.

[0038] like Figure 1 As shown, in this embodiment, an air pump 304 is provided on the air inlet end of the air blowing tube 302, and an electric control switch 305 for manual start or stop is provided on the air pump 304, that is, the electric control switch 305 is installed on the power line of the air pump 304, and the air pump 304 is started or stopped by connecting or disconnecting the power line, thereby achieving the purpose of controlling the air pump 304.

[0039] like Figure 1 As shown, in this embodiment, a trumpet-shaped inlet portion 3011 is provided at the connection between the discharge pipe 301 and the circulation pipe 30 to form a smooth transition arc surface, which can avoid unnecessary collision when the foamed particles are turned by blowing through the blowing pipe 302, thereby improving the flow of the output.

[0040] Furthermore, if Figure 1As shown, in this embodiment, the inlet of the suction box 201 is arranged on one end of the supply box 10, and the bottom of the supply box 10 is provided with an inclined surface 101 inclined toward the inlet direction of the suction box 201; the other end of the circulation pipe 30 is arranged on the top surface or side surface of the inclined surface 101 of the supply box 10 relative to the highest point position.

[0041] Specifically, the design of the inclined surface 101 is conducive to concentrating the materials in the feed box 10 at one end of the outlet of the feed box 10 by their own weight, which is convenient for the discharge mechanism 20 to suck and transport. At the same time, the filler entering through the circulation pipe 30 is input to the highest point of the inclined surface 101 of the feed box 10, which can avoid clogging of the outlet of the circulation pipe 30 and improve practicality.

[0042] like Figure 3 As shown, in this embodiment, a detector for detecting the material level is provided in the feed box 10, or an observation window 102 for observing the material is provided on the feed box 10. For example, by setting a GP2D12 model infrared detector, the height of the filler in the feed box 10 can be known to judge the amount of filler in the feed box 10 so as to replenish it in time. Alternatively, by directly checking and judging through the observation window, the situation of insufficient filler in the feed box 10 is avoided, thereby improving practicality.

[0043] like Figure 1 As shown, in this embodiment, the air blowing pipe 302 is provided with an air flow regulating valve 3021 and an air pressure detector 3022, and the air pressure detector 3022 is of the DP-702LH model. By controlling the opening of the air flow regulating valve 3021, the air output of the air blowing pipe 302, that is, the size of the air flow, is controlled to control the discharge amount. At the same time, the air pressure in the air blowing pipe 302 can be known through the air pressure detector 3022, so as to determine whether the air blowing pipe 302 has good air tightness; at the same time, the air pressure value in the air blowing pipe 302 can be known, so as to adjust as needed and improve practicality.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
