[0041] Polyurethane (PU) is a polymer material with excellent elasticity, wear resistance, and chemical corrosion resistance. It can also be formulated into different forms such as flexible foam, rigid foam, and elastomers. It has a wide range of applications (such as automobiles, construction, and electronics). However, the chemical reaction of PU (polymerization of polyols and isocyanates) is characterized by rapid curing and high proportional sensitivity. Traditional manual mixing is difficult to meet the requirements of uniformity and aging.

[0042] A PU (polyurethane) injection machine is an industrial device specifically designed for mixing, metering, and injecting polyurethane materials. It is widely used in automobile manufacturing, furniture production, building insulation, electronic packaging, and shoe material manufacturing.

[0043] Existing PU (polyurethane) filling machines typically include multiple solvent tanks for storing raw materials. These solvents may contain impurities, which can be mixed in during the raw material mixing process, thus affecting the purity of the final polyurethane material.

[0044] To address the problems existing in the prior art, this application provides a metering device for a filling machine and a filling machine.

[0045] Please see Figures 1 to 5 The present invention provides a metering device for a filling machine, comprising a filter body 1 having a first filter chamber 101. The filter body 1 includes an inlet 102, a first flow channel 103, a second flow channel 104, and an outlet 105. The inlet 102 is connected to the first filter chamber 101, and the inlet 102 and the outlet 105 are connected through the first flow channel 103 and the second flow channel 104. A filter assembly 2 is disposed in the first filter chamber 101, and a pump assembly 3 is disposed on the filter body 1. The pump assembly 3 includes a pump body 301, a motor 302, and a reducer 303. The inlet of the pump body 301 is connected to the first flow channel 103, and the outlet of the pump body 301 is connected to the second flow channel 104. The metering device also includes a mounting plate 4. The filter body 1 and the mounting plate 4 are detachably connected. The motor 302 is connected to the mounting plate 4 through a bracket 401, and the motor 302 is disposed above the filter body 1.

[0046] In this embodiment, the pump body 301, the motor 302, and the reducer 303 constitute the pump assembly 3. The pump assembly 3 provides power for the flow of raw materials. It can be understood that by controlling the speed of the motor 302, the flow rate of the raw materials can be controlled, thereby realizing the metering function. The motor 302 can be a conventional motor 302 available on the market, which will not be described in detail here. In addition, in this embodiment, a flow channel for the raw materials to pass through is formed by the liquid inlet 102-first filter chamber 101-filter assembly 2-first flow channel 103-pump assembly 3-second flow channel 104-liquid outlet 105. The filter assembly 2 is set in the first filter chamber 101. The filter assembly 2 can filter the impurities carried in the raw materials, improve the purity of the raw materials, and thus ultimately improve the purity of the polyurethane mixture. In addition, a valve 12 can be set at the liquid inlet 102 to control the opening and closing of the liquid inlet 102.

[0047] In other embodiments of this application, please refer to Figure 5 One end of the first filter chamber 101 is open, so the filter assembly 2 can be detachably installed in the first filter chamber 101, which facilitates the replacement, disassembly and cleaning of the filter assembly 2 and ensures the filtration effect of the filter assembly 2.

[0048] For a more detailed explanation of the working principle of filter component 2, please refer to other embodiments of this application. Figure 6 The filter assembly 2 includes a filter 201 and a filter screen (not shown in the figure). The filter 201 has a second filter chamber 2011 inside. One end of the second filter chamber 2011 is open and is connected to the first flow channel 103. The outer periphery of the filter 201 is also provided with a plurality of through holes 2012, which connect the first filter chamber 101 and the second filter chamber 2011. The filter screen is wrapped around the outer periphery of the filter 201.

[0049] Therefore, the raw material first enters the first filter chamber 101 through the inlet 102, and then passes through the filter screen to filter various impurities in the raw material. After filtration, the raw material enters the second filter chamber 2011 through the through hole 2012. The second filter chamber 2011 is connected to the first flow channel 103. Therefore, the filtered raw material enters the pump body 301 through the first flow channel, and then flows to the outlet 105 through the second flow channel 104. It can be understood that the filter screen and the filter 201 can be fixedly connected, or they can be detached connected by clamps, wires, snap-fits, etc., as long as the filter screen can be fixed to the outer periphery of the filter 201. The cross-sectional shape of the through hole 2012 can be, but is not limited to, circular, triangular, polygonal or irregular shape, as long as the filtered raw material can pass through. The cross-sectional area of ​​the through hole 2012 is not limited here.

[0050] In other embodiments of this application, please refer to [link / reference]. Figure 1-5 The filter body 1 also includes a cleaning port 5 communicating with the first filter chamber 101 and a first sealing cover 6. The cleaning port 5 is disposed on the filter body 1 opposite to the liquid inlet 102. The first sealing cover 6 is detachably disposed on the cleaning port 5. The cleaning port 5 is communicating with the first filter chamber 101 and their positions are corresponding. It can be understood that during the process of filtering the raw material by the filter assembly 2, solid impurities will accumulate in the first filter chamber 101 due to the filtration obstruction of the filter assembly 2. When there are too many solid impurities, they will cause obstruction in the first filter chamber 101, thereby affecting the smooth passage of the raw material. In order to ensure the smooth passage of the raw material, a cleaning port 5 is provided in this embodiment. When there are no impurities accumulating in the first filter chamber 101, the cleaning port 5 is sealed by the detachable first sealing port. When there are impurities accumulating in the first filter chamber 101, the motor 302 is turned off, the pump assembly 3 is stopped, and then the first sealing port is opened. The impurities in the first filter chamber 101 are processed through the cleaning port 5, thereby achieving the function of unblocking the first filter chamber 101 and ensuring the smooth passage of the raw material.

[0051] In other embodiments of this application, please refer to [link / reference]. Figure 1 and Figure 5 The filter body 1 also includes a drain port 7 connected to the first filter chamber 101 and a second sealing cover 8. The drain port 7 is located at the bottom of the filter body 1, and the second sealing cover 8 is detachably mounted on the drain port 7. When the metering device is no longer in operation, in order to prevent the raw material from remaining in the metering device, the second sealing cover 8 is opened, and the remaining raw material in the metering device is discharged to the outside of the device through the drain port 7 located at the bottom of the filter body 1.

[0052] To ensure the temperature of the raw material during the conveying process, in some other embodiments of this application, the metering device further includes a heat-conducting component, including a heat-conducting channel (not shown in the figure), a channel inlet 901, and a channel outlet 902. The heat-conducting channel is disposed at the bottom of the filter body 1, and the channel inlet 901 and the channel outlet 902 are respectively disposed at both ends of the heat-conducting channel. The heat-conducting channel is used to supply the flow of the heat-conducting medium. Specifically, the heat-conducting channel is located below the first filter chamber 101. Through the flow of the heat-conducting medium in the heat-conducting channel, the heat of the heat-conducting medium is transferred to the raw material in the first filter chamber 101, thereby ensuring the temperature of the raw material.

[0053] In some other embodiments of this application, the metering device further includes a pressure sensor 10 and a detection port 11. The detection port 11 is disposed on the filter body 1 and communicates with the second flow channel 104. The pressure sensor 10 is disposed at the detection port 11. The pressure sensor 10 is used to detect the pressure of the raw material in real time to prevent abnormal situations such as excessively high or low pressure.

[0054] In some other embodiments of this application, the first filter chamber 101 penetrates the filter body 1, one end of the first filter chamber 101 is provided with a filter assembly 2, and the other end is provided with a fixing member 13, which is threadedly connected to the filter assembly 2.

[0055] This utility model also provides a filling machine, including a solvent tank, a filling device, and a metering device for the filling machine as provided in the above embodiments. The metering device is mounted on the solvent tank via a mounting plate 4, with an inlet 102 communicating with the interior of the solvent tank and an outlet 105 communicating with the filling device. Since the filling machine provided by this utility model includes the metering device for the filling machine provided in the above embodiments, it has the same technical effects as the metering device for the filling machine provided in the above embodiments, and will not be described again here.

[0056] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
