Description

Technical Field

[0001] This utility model relates to the field of resin technology, and in particular to a resin metering component and a precise epoxy resin dispensing device. Background Technology

[0002] Epoxy resin systems typically consist of resin (component A) and curing agent (component B). Some formulations also include auxiliary components such as fillers and pigments (which may be labeled as components C, D, etc.). The curing reaction of this system is extremely sensitive to the component ratio; deviations in the ratio can significantly affect the performance of the final product.

[0003] Epoxy resin and curing agent are typically high-viscosity liquids, requiring flow meters or weighing sensors for precise mixing during the metering process. However, the viscosity of these two components is significantly affected by temperature, exhibiting marked differences under different temperature conditions. Currently, in actual production, the structural design of delivery pipelines is often relatively simple, lacking effective temperature control measures and making them susceptible to fluctuations in ambient temperature. This leads to viscosity instability between different batches of epoxy resin during transportation, consequently affecting the detection accuracy of the flow meter and ultimately causing mixing deviations.

[0004] Therefore, we propose a resin metering component and a precise epoxy resin dispensing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a resin metering component and a precise epoxy resin dispensing device.

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

[0007] A resin metering assembly, comprising:

[0008] The feed pipe has a serpentine connecting pipe fixedly connected to one end, and a discharge pipe fixedly connected to one end of the connecting pipe. A flow meter is provided on the outer wall of the connecting pipe.

[0009] Two covers are fitted between the feed pipe and the discharge pipe. The connecting pipe is located inside the covers. The two covers are fixed together by bolts. Two connecting plates are fixed on the top inner wall and the bottom inner wall of the covers. A heating pipe is fixed between two adjacent connecting plates. Temperature sensors are fixed on the bottom inner wall and the inner wall of the connecting pipe. A clearance opening is provided on the opposite side of the covers to allow space for the flow meter, feed pipe and discharge pipe.

[0010] The controller is fixed to one side of the outer wall of one of the enclosures.

[0011] In one possible design, the outer wall of the feed pipe is provided with a first control valve and a water inlet pipe with a control valve, the water inlet pipe being located between the first control valve and the connecting pipe, and the outer wall of the discharge pipe is provided with a second control valve and a water outlet pipe, the water outlet pipe being located between the second control valve and the connecting pipe.

[0012] In one possible design, the inner wall of the cover is bonded with insulating cotton.

[0013] In one possible design, two positioning plates are fixed to the inner wall of one side of the cover, and four positioning rings are fixed to the outer wall of the connecting pipe. The positioning rings and positioning plates are used in conjunction. An arc-shaped groove is opened on one side of the positioning plate, and the arc-shaped groove is adapted to the outer wall of the connecting pipe.

[0014] In one possible design, both the feed pipe and the discharge pipe are equipped with quick connectors at one end, and a lead wire hole is provided through one side of the outer wall of the cover.

[0015] An epoxy resin precision dispensing device includes a resin metering component.

[0016] In this application, during use, the first control valve and the second control valve are in the open state, and the inlet pipe and the outlet pipe are in the closed state. The resin passes through the feed pipe, the connecting pipe and the outlet pipe in sequence. The temperature sensor inside the connecting pipe and the temperature sensor inside the cover monitor the temperature inside and outside the connecting pipe respectively, and transmit the signal to the controller. The controller adjusts the operating power of the heating tube so that the temperature of the resin remains stable when it flows in the connecting pipe.

[0017] When cleaning the pipes, close the first control valve and the second control valve, and then inject water from the inlet pipe to flush and clean the inner wall of the pipes.

[0018] Beneficial effects: In this utility model, the resin metering component and epoxy resin precision dispensing equipment, through the setting of structures such as the cover, temperature sensor and heating tube, can monitor and adjust the temperature of the cover in real time, so that the temperature of the resin can remain stable when passing through the connecting pipe, and ensure the flow meter's accurate detection of the fluid.

[0019] In this utility model, the resin metering component and epoxy resin precision dispensing equipment, through the setting of the cover connecting plate and quick connector and other structures, can facilitate the disassembly and assembly of the cover and feed pipe and other structures, providing convenience for later maintenance.

[0020] In this utility model, the resin metering component and epoxy resin precision dispensing equipment, through the setting of structures such as positioning rings and positioning plates, can position the cover after assembly, preventing the cover from shifting randomly.

Detailed Implementation

[0025] 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.

[0026] In one embodiment: Refer to Figures 1-3 A resin metering assembly includes: a feed pipe 1, one end of which is fixedly connected to a serpentine connecting pipe 2. The connecting pipe 2 has a serpentine bend structure, which helps to prolong the residence time of the resin in the pipeline and make temperature regulation more efficient. The other end of the connecting pipe 2 is fixedly connected to a discharge pipe 3. A flow meter 7 is provided on the outer wall of the connecting pipe 2 for detecting the volumetric flow rate of the resin flowing through the connecting pipe.

[0027] The entire connecting pipe 2 area is surrounded by two covers 4. The covers 4 are fitted onto the section between the inlet pipe 1 and the outlet pipe 3 and are bolted together to form a closed, insulated cavity. The covers 4 have recesses to provide installation and operating space for the flow meter 7, the inlet pipe 1, and the outlet pipe 3. Two connecting plates 16 are fixed to the top and bottom inner walls of each cover 4, and heating pipes 17 are fixedly installed between adjacent connecting plates 16. The heating pipes 17 are used to heat the internal space of the covers 4, thereby indirectly regulating the temperature of the resin inside the connecting pipe 2.

[0028] To monitor the temperature in real time, temperature sensors 15 are fixedly installed on the inner walls of the top and bottom of the enclosure 4, as well as on the inner wall of the connecting pipe 2. These temperature sensors 15 are used to monitor the heating environment and the actual temperature of the resin, respectively, and provide feedback signals for temperature control.

[0029] A controller 6 is fixedly installed on one side of the outer wall of one of the enclosures 4. The controller 6 is electrically connected to all temperature sensors 15, heating tubes 17 and flow meters 7, and is used to receive sensor signals and adjust the operating power of heating tubes 17 according to preset logic to achieve closed-loop temperature control.

[0030] To further enhance the functionality of the components, a first control valve 12 and a water inlet pipe 8 with a control valve are installed on the outer wall of the feed pipe 1, with the water inlet pipe 8 located between the first control valve 12 and the connecting pipe 2. A second control valve 13 and a water outlet pipe 9 are installed on the outer wall of the discharge pipe 3, with the water outlet pipe 9 located between the second control valve 13 and the connecting pipe 2. These valves and pipes together form a cleaning circuit.

[0031] This application can be used in the field of resins, or in other fields applicable to this application.

[0032] In another embodiment: a resin metering component applied to the resin field;

[0033] In another aspect of this embodiment, thermal insulation cotton 14 is adhered to the inner wall of the cover 4 to reduce heat loss, improve thermal efficiency and maintain temperature stability.

[0034] To ensure accurate positioning of the connecting pipe 2 during assembly, two positioning plates 11 are fixed on the inner wall of one side of the cover 4, and four positioning rings 10 are fixed on the outer wall of the connecting pipe 2. The positioning plates 11 have arc-shaped grooves that fit the outer wall of the connecting pipe 2. During assembly, the positioning rings 10 work in conjunction with the positioning plates 11 to effectively prevent the cover 4 from shifting or rotating.

[0035] To facilitate pipe connection and cable arrangement, quick connectors are provided at one end of the feed pipe 1 and the discharge pipe 3, and a lead wire hole 5 is provided through the outer wall of one side of the cover 4 for the passage of power supply and signal cables.

[0036] An epoxy resin precision dispensing device includes the resin metering component described in any of the above embodiments.

[0037] The working process of this utility model is as follows:

[0038] During normal metering and batching, the first control valve 12 and the second control valve 13 are open, while the valves on the inlet pipe 8 and the outlet pipe 9 are closed. The resin material flows sequentially through the inlet pipe 1, the connecting pipe 2, and the outlet pipe 3. During the flow, each temperature sensor 15 continuously monitors the temperature and transmits the signal to the controller 6. The controller 6 adjusts the power of the heating tube 17 to maintain the temperature of the resin in the connecting pipe 2 at a constant set value, thereby maintaining its viscosity stability. The flow meter 7 performs accurate measurements under these stable conditions.

[0039] When the pipeline needs to be cleaned, first close the first control valve 12 and the second control valve 13 to block the main material passage. Then, open the valves on the inlet pipe 8 and the outlet pipe 9, and introduce cleaning fluid (e.g., water) into the inlet pipe 8. The cleaning fluid will flow through the connecting pipe 2 and flush the inner wall of the pipeline, and finally be discharged through the outlet pipe 9 to complete the cleaning process.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of the flow meter 7, temperature sensor 15 and heating tube 17 are all conventional methods 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.

[0041] 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.

[0042] 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.
