Description

Technical Field

[0001] This utility model relates to the field of epoxy resin production technology, and more specifically, to an adjustable micro feed valve for epoxy resin production. Background Technology

[0002] Epoxy resin is a high molecular weight polymer, referring to a class of polymers whose molecules contain two or more epoxy groups. Due to its strong adhesion, low shrinkage, and excellent mechanical and electrical properties, epoxy resin is widely used in coatings, adhesives, and electronic appliances. During the epoxy resin production process, especially during the feeding process, flow control valves are frequently used to regulate the feed flow.

[0003] Existing feed valves, such as the adjustable micro feed valve for epoxy resin production with patent number CN211914454U, feature a turntable with multiple third mounting slots. Each third mounting slot corresponds to a filter screen. To select the appropriate filter screen, the turntable is rotated, facilitating the screening of large particles and sludge in the epoxy resin. However, this feed valve requires manual rotation of the turntable. Furthermore, during adjustment, the corresponding filter screen number is observed through an observation window. After selecting the appropriate filter screen, the turntable is rotated to align the filter screen with the outlet pipe, and finally, the outlet pipe is installed in the third mounting slot. This conversion method is difficult to position during installation and is time-consuming and labor-intensive. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an adjustable micro valve for epoxy resin production that is easy to position and quickly replace the filter screen.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 and Figure 2This utility model provides an adjustable micro feed valve for epoxy resin production, comprising: a valve body 10 having a discharge port 11 disposed at the bottom of the valve body 10; a rotating mechanism 20 disposed on the valve body 10, having a rotating disk 21 rotatably disposed at the bottom of the valve body 10; a plurality of filter components 30, arranged in a ring around the center of the rotating disk 21 and passing through the rotating disk 21, for filtering impurities in the epoxy resin; the filter components 30 being disposed opposite to the discharge port 11; and a limiting mechanism 40 including a plurality of positioning holes 41 and an elastic fixing component 42. The plurality of positioning holes 41 and the plurality of filter components 30 are concentrically arranged around the bottom of the rotating disk 21, and are respectively disposed on one side of the filter components 30. The elastic fixing component 42 is disposed at the bottom of the valve body 10 corresponding to one of the positioning holes 41, for automatically popping out and inserting into the positioning hole 41 to fix the rotating disk 21. The marking mechanism 50 has a marking disk 52 located at the top of the valve body 10 and connected to the output end of the rotating mechanism 20, used to mark the positions of several filter components 30 and rotate together with the rotating disk 21.

[0017] Understandably, the rotating mechanism 20 is a component that provides rotational motion; for example, it can be an electrically driven rotating mechanism 20 or a hydraulically driven rotating mechanism 20, but it is not limited to these. The rotating disk 21 is a disk-mounted component that houses multiple filter components 30; for example, it can be a circular rotating disk 21 or a square rotating disk 21, but it is not limited to these. The filter components 30 are components that filter out large particles and other impurities from the epoxy resin; for example, they can be bag filters or cartridge filters, but they are not limited to these. The limiting mechanism 40 is a component that limits the single rotation angle of the rotating disk 21; for example, it can be an indexing pin or a ratchet and pawl mechanism, but it is not limited to these. The positioning hole 41 is a hole for limiting the rotation of the rotating disk 21; for example, it can be a positioning pin hole or a threaded hole, but it is not limited to these. Multiple positioning holes 41 and multiple filter components 30 are correspondingly arranged to fix the rotation angle of the rotating disk 21. For example, the positioning holes 41 can be arranged in a ring on the rotating disk 21, and the angles between the positioning holes 41 are all the same. Alternatively, the elastic fixing component 42 can be inserted into the positioning hole 41 to fix the rotating disk 21 and prevent the rotating disk 21 from rotating left or right. For example, it can be a positioning pin or a telescopic rod mechanism, but it is not limited to these. The marking mechanism 50 is a mechanism that marks the position of the corresponding filter component 30. For example, it can be a shaft-scale mechanism or a probe-lever trigger marking mechanism, but it is not limited to these. The marking disk 52 is a component on the top of the valve body 10 that marks the position of the corresponding filter component 30. For example, it can be a digital marking disk 52 or a graphic marking disk 52, but it is not limited to these.

[0018] As described above, the equipment is equipped with a limiting mechanism 40, which has positioning holes 41 corresponding to multiple filters, and an elastic fixing component 42. When the filter component 30 needs to be replaced, the elastic fixing component 42 is pulled out from the positioning hole 41, and the rotating mechanism 20 is started to rotate the rotating disk 21. When the elastic fixing component 42 aligns with the next positioning hole 41, it is inserted into the positioning hole 41, fixing the rotating disk 21. This allows workers to quickly replace the filter component 30, improving production efficiency. The equipment also has an indicator plate 52 installed on the top of the valve. The indicator plate 52 marks the position of each filter component 30, and when the rotating disk 21 rotates, the rotating shaft 20 drives the indicator plate 52 to rotate synchronously, allowing workers to better observe which filter component 30 is being used, facilitating quick replacement of the corresponding filter component 30 and further improving production efficiency.

[0019] Optionally, in some embodiments, please refer to Figure 2 The filter assembly 30 includes: a through-hole 31 disposed on the rotating disk 21; and a filter membrane 32 disposed within the through-hole 31 for filtering impurities within the epoxy resin.

[0020] Understandably, filter membrane 32 is a filter component that separates epoxy resin from impurities. For example, it can be a polypropylene filter membrane 32 or a polytetrafluoroethylene filter membrane 32, but it is not limited to these.

[0021] With this configuration, when the epoxy resin passes through the filter membrane 32, the filter membrane 32 filters out impurities in the epoxy resin, preventing impurities from affecting subsequent processing.

[0022] Optionally, in some embodiments, the adjustable micro-feed valve for epoxy resin production further includes a discharge pipe 60 disposed on the discharge port 11 and connected to the through hole 31. The through hole 31 is provided with threads for connecting the discharge pipe 60.

[0023] Understandably, the discharge pipe 60 is a component that can be detachably connected to the through hole 31 and discharges the filtered epoxy resin to the valve body 10. For example, it can be connected by a threaded connection or by a snap-fit ​​connection, but it is not limited to these methods.

[0024] Optionally, in some embodiments, the rotating mechanism 20 further includes a rotating shaft 23 disposed inside the valve body 10 and passing through the top end of the valve body 10, and connected to the rotating disk 21 and the marking disk 52. It also includes a rotating driver 22 disposed outside the top end of the valve body 10, with its output end connected to the rotating shaft 23, for driving the rotating disk 21 and the marking disk 52 to rotate synchronously.

[0025] Understandably, the rotating shaft 23 is a shaft that needs to connect both the rotating disk 21 located at the bottom of the valve body 10 and the marking disk 52 located at the top of the valve body 10, driving the rotating disk 21 and the marking disk 52 to rotate synchronously. For example, it can be a single rotating shaft, connected to the rotating disk 21, passing through the top of the valve body 10, and then connecting to the marking disk 52. Alternatively, it can be two rotating shafts, each connected to its respective rotating disk 21 and marking disk 52, and then connected together by welding or threading, etc., but is not limited to these methods. The rotary actuator 22 is a component that provides rotational power. For example, it can be an electrically driven rotary actuator 22 or a hydraulically driven rotary actuator 22, but is not limited to these methods.

[0026] With this configuration, the rotating disk 21 and the marking disk 52 are connected by a rotating shaft, and the rotating disk 21 and the marking disk 52 are driven to rotate synchronously, so that the marking disk 52 can mark the position of the corresponding filter component 30 at any time, which is convenient for workers to observe.

[0027] Optionally, in some embodiments, please refer to Figure 1 The marking mechanism 50 includes: a groove 51, disposed opposite to the discharge port 11 on the top outer end of the valve body 10, for indicating the position of the discharge port 11; and a marking disk 52, disposed opposite to the rotating disk 21 on the top outer outer end of the valve body 10 and connected to the output end of the rotary driver 22, for indicating whether the filter assembly 30 is aligned with the discharge port 11. The marking disk 52 is engraved with several marks for correspondingly marking several of the filter assemblies 30. The rotary driver rotates, causing the numbers on the marking disk 52 to rotate and align with the groove 51.

[0028] Understandably, the groove 51 marks the location of the outlet 11 on the top of the valve body 10. A label for the outlet 11 can be affixed inside the groove 51; for example, it could be a square groove 51 or an arrow-shaped label, but it is not limited to these. The marking disc 52 is engraved with marks corresponding to the multiple filter components 30, with one mark representing one filter component 30. These marks can be numerical or color-coded, but are not limited to these. When the mark on the marking disc 52 corresponds to the groove 51, it indicates that the corresponding filter component 30 is connected to the outlet 11.

[0029] With this configuration, the label plate 52 rotates together with the rotating plate 21. When the rotating plate 21 rotates and drives the corresponding filter component 30 to the discharge port 11, the corresponding mark on the label plate 52 corresponds to the groove 51, making it convenient for workers to observe which filter component 30 is being used.

[0030] Optionally, in some embodiments, please refer to Figure 3The elastic fixing assembly 42 includes: a mounting tube 421 disposed on the mounting hole 13; a tension rod 422 disposed inside the mounting tube 421 for engaging with the positioning hole 41 to fix the rotating disk 21; and an elastic element 423 disposed on the tension rod 422 and located inside the mounting tube 421 for resetting the tension rod 422.

[0031] Understandably, the mounting tube 421 is a mounting tube 421 connected to the mounting hole 13, for example, it can be a fixed welded connection or a threaded connection, but is not limited to these. The tension rod 422 is a component that extends into the positioning hole 41 to fix the rotating disk 21, and shortens to separate from the positioning hole 41 and thus relax the rotating disk 21, for example, it can be a manual tension rod 422 or an electric tension rod 422, but is not limited to these. The elastic element 423 is a component that automatically pushes the tension rod 422 out and resets it to be inserted into the positioning hole 41 when the tension rod 422 is aligned with the positioning hole 41, for example, it can be a spring or an elastic sheet, but is not limited to these.

[0032] With this configuration, when the rotating disk 21 needs to be rotated, the tension rod 422 is pulled out of the positioning hole 41, and then the rotating disk 21 is rotated. When the tension rod 422 rotates to the next positioning hole 41 position and is aligned with the positioning hole 41, it automatically pops out and inserts into the positioning hole 41, preventing the rotating disk 21 from continuing to rotate, thereby enabling faster replacement of the filter component 30.

[0033] As can be seen from the above, when the filter assembly 30 needs to be replaced, first remove the discharge pipe 60 from the through hole 31, then pull out the tension rod 422 in the elastic fixing assembly 42 from the positioning hole 41, rotate the rotating disk 21, and when the elastic fixing assembly 42 aligns with the next positioning hole 41, the discharge port 11 and the filter assembly 30 are aligned. The elastic element 423 in the fixing mechanism automatically drives the tension rod 422 to spring back and insert into the positioning hole 41. Repeat the above steps until the filter assembly 30 to be used and the discharge port 11 are aligned, and then put the discharge pipe 60 back into the through hole 31.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
