Description

Technical Field

[0001] This utility model relates to the field of resin technology, and in particular to a quantitative conveying component and an unsaturated resin dispensing device. Background Technology

[0002] Unsaturated resin is a thermosetting polymer that is widely used in composite materials, artificial stone, and coatings. In unsaturated resin batching equipment, screw pumps are often selected as precision metering pumps for resin due to their advantages of stable delivery, low pulsation, and low shear force on the medium.

[0003] Because the viscosity of unsaturated resin changes significantly with temperature, when using a screw pump for delivery, an insulation jacket is usually installed in the delivery section of the pump body to prevent the viscosity from increasing due to temperature drop, reduce the resistance of the screw pump delivery, and ensure quantitative delivery. The connection pipe at the inlet end of the screw pump often lacks effective constant temperature protection measures due to its relatively simple structure, which makes it easy for heat to be lost in this area, and the temperature drops significantly, thus affecting the flowability of the resin and the quantitative delivery performance of the pump.

[0004] Therefore, we propose a quantitative conveying component and an unsaturated resin batching device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quantitative conveying component and an unsaturated resin batching device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quantitative delivery component, comprising:

[0008] A screw pump, wherein the inlet end of the screw pump is fixedly connected to a connecting pipe, and a flow meter is provided on the outer wall of the connecting pipe;

[0009] Two connecting covers are fitted on the outside of the connecting pipe. The two connecting covers are fixedly connected to a connecting shell on the side that is far apart from each other. One side of the connecting shell is fixedly connected to an insert pipe. A flexible hose is inserted between the two insert pipes. The flexible hose is wrapped around the outside of the screw pump. A fan is fixedly installed on the inside of the connecting shell.

[0010] The inner wall of the connecting cover is fixed with two fixing plates, and multiple heating tubes are fixedly inserted between the two fixing plates. The heating tubes are arranged around the connecting tube. An arc-shaped groove is opened on one side of the fixing plate. Temperature sensors are fixed on the inner wall of the connecting cover and the inner wall of the connecting tube.

[0011] In one possible design, the two connecting covers are fixedly connected by a plurality of connectors, each connector including two connecting blocks, which are respectively welded to one side of the two connecting covers. A bolt passes between the two connecting blocks, and a nut is threaded onto one end of the bolt.

[0012] In one possible design, two positioning blocks are fixed to the outer wall of the connecting pipe, and the two positioning blocks are located between two fixing plates.

[0013] In one possible design, the inner wall of the connecting cover is bonded with thermal insulation cotton, and a controller is fixed to one side of the outer wall of one of the connecting covers.

[0014] In one possible design, a pressure gauge is provided on the outer wall of the connecting pipe.

[0015] An unsaturated resin batching device includes a metering conveying component.

[0016] In this application, during the resin delivery process of the screw pump, the heating tube is turned on. During the resin flow, temperature sensors inside and outside the connecting tube monitor the temperature and send the signal to the controller. The controller adjusts the operating power of the heating tube in real time according to the signal, thereby adjusting the temperature inside and outside the connecting tube to ensure that the resin is within a stable temperature range, which facilitates the delivery of resin by the screw pump. At the same time, the fan is turned on so that hot air passes through the hose and over the outside of the screw pump delivery section to prevent the resin from losing heat.

[0017] Beneficial effects: In this utility model, the quantitative conveying component and unsaturated resin batching equipment, through the setting of structures such as connecting cover, heating tube and heat insulation cotton, can adjust the heating tube according to the temperature inside and outside the connecting tube, thereby ensuring that the resin is kept in a stable temperature range, and can also keep the screw pump conveying section warm, which facilitates the screw pump to quantitatively convey the resin.

[0018] In this utility model, the quantitative conveying component and unsaturated resin batching equipment, through the setting of connecting parts and other structures, make it easy for people to disassemble and assemble the connecting cover, which provides convenience for later maintenance;

[0019] In this utility model, the quantitative conveying component and unsaturated resin dispensing equipment can position the fixing plate and connecting cover by setting the positioning block and other structures, so as to avoid the connecting cover shifting randomly after assembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In one embodiment: Refer to Figures 1-3 A quantitative delivery assembly includes: a screw pump 1, the inlet end of which is fixedly connected to a connecting pipe 2. A flow meter 5 is installed on the outside of the connecting pipe 2 for real-time monitoring of the resin flow rate through the connecting pipe 2.

[0026] Two connecting covers 6 are fitted around the outside of the connecting pipe 2. Each connecting cover 6 has a connecting shell 7 fixedly connected to the side of the connecting cover 6 furthest from the other. One side of the connecting shell 7 is connected to an insert pipe, and a flexible hose 8 is inserted between the two insert pipes, wrapped around the outside of the screw pump 1. A fan is installed inside the connecting shell 7 to generate airflow, allowing hot air to flow through the flexible hose 8, thereby insulating the delivery section of the screw pump 1.

[0027] Two fixing plates 9 are fixedly installed on the inner wall of each connecting cover 6, and multiple heating tubes 10 are fixedly installed through the two fixing plates 9. The heating tubes 10 are arranged around the connecting tube 2 to heat the connecting tube 2 and the resin flowing inside. An arc-shaped groove is formed on one side of the fixing plate 9. The inner diameter of the arc-shaped groove is slightly larger than the outer diameter of the connecting tube 2 to facilitate assembly and maintain the relative position between the heating tubes 10 and the connecting tube 2. Temperature sensors 11 are installed on the inner wall of the connecting cover 6 and the inner wall of the connecting tube 2, respectively, to monitor the temperature of the external environment and the internal material of the connecting tube 2.

[0028] The two connecting covers 6 are fixedly connected by multiple connectors. Each connector includes two connecting blocks 13, which are welded to the outer surfaces of the two connecting covers 6 respectively. A bolt 14 is inserted between the two connecting blocks 13, and one end of the bolt 14 is equipped with a nut. By tightening the nut, the two connecting covers 6 can be firmly connected, and it also facilitates disassembly for later maintenance.

[0029] This application can be used in the field of resins, or in other fields applicable to this application.

[0030] In another embodiment: a metering delivery assembly applied to the resin field;

[0031] In another aspect of this embodiment, two positioning blocks 4 are also fixedly provided on the outer wall of the connecting pipe 2, and these two positioning blocks 4 are located between the two fixing pieces 9. The positioning blocks 4 are used to limit the axial position of the fixing pieces 9 and the connecting cover 6 to prevent the connecting cover 6 from shifting after assembly.

[0032] The inner wall of the connecting cover 6 is covered with insulating cotton 12 to reduce heat loss, improve heating efficiency, and maintain temperature stability. A controller is installed on the outer wall of one side of one of the connecting covers 6. The controller is electrically connected to the temperature sensor 11, the heating tube 10, and the fan to receive temperature signals and adjust the operating power of the heating tube 10 and the operating status of the fan accordingly.

[0033] A pressure gauge 3 is also installed on the outer wall of the connecting pipe 2 to monitor the fluid pressure inside the connecting pipe 2 in real time and provide a reference for the system's operating status.

[0034] In actual operation, when the screw pump 1 starts conveying resin, the heating tube 10 begins to work and heats the connecting tube 2. The temperature sensor 11 monitors the internal and external temperatures of the connecting tube 2 in real time and transmits the signal to the controller. The controller dynamically adjusts the power of the heating tube 10 based on the difference between the preset temperature range and the measured temperature value, thereby achieving precise control of the resin temperature and ensuring stable flow at a suitable viscosity. This facilitates the quantitative conveying by the screw pump 1. The fan can adjust the temperature distribution inside the connecting cover 6 as needed through airflow. The insulation cotton 12 effectively reduces heat loss and improves energy efficiency. The pressure gauge 3 and flow meter 5 provide necessary parameter data for system monitoring.

[0035] In addition, an unsaturated resin batching device is provided, including the quantitative conveying component described in any one of the above, for realizing a stable and accurate conveying function of unsaturated resin during the batching process.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the screw pump 1, flow meter 5, heating tube 10 and temperature sensor 11 are all conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations, but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
