Description

Technical Field

[0001] This utility model relates to the field of epoxy AB glue production, specifically to a device for removing air bubbles in epoxy AB glue production. Background Technology

[0002] Epoxy AB adhesive is a two-component adhesive, mainly composed of epoxy resin and a curing agent. Epoxy resin contains two or more epoxy groups in its molecular structure, enabling it to form a three-dimensional cross-linked cured compound under appropriate chemical reagents and conditions.

[0003] Epoxy AB adhesive, a two-component adhesive consisting of epoxy resin (A glue) and a curing agent (B glue), is highly susceptible to air bubble formation during mixing and curing due to stirring, pouring operations, or chemical reactions. These air bubbles not only affect the appearance and adhesive properties of the adhesive but also lead to the formation of micropores or delamination after curing, significantly reducing the mechanical strength and service life of the product.

[0004] Traditional degassing methods include vacuum degassing, centrifugal degassing, and heating degassing, but all have limitations: vacuum degassing requires the use of open containers and is prone to causing "false boiling" due to excessive vacuuming; centrifugal degassing can easily cause filler stratification in adhesives containing fillers, and the equipment operation is complicated; heating methods require strict temperature control to avoid accelerating adhesive curing. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes an epoxy AB glue production bubble removal device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A bubble removal device for epoxy AB adhesive production includes a bubble removal mounting shell, a bubble removal mounting assembly inside the bubble removal mounting shell, a feeding mounting assembly on one side of the bubble removal mounting assembly, and a discharging mounting assembly on one side of the bubble removal mounting shell.

[0008] To achieve the purpose of bubble removal during installation, the bubble removal installation assembly includes a reciprocating screw, a movable slider that is fitted around the reciprocating screw, a screw pad mounting bracket that is installed around the movable slider, and a nylon filter membrane installed inside the screw pad mounting bracket. A limit mounting plate is movably connected to the reciprocating screw and is connected to the bubble removal installation housing. One end of the reciprocating screw is connected to a rotary drive shaft, and a stirring rod is connected to the rotary drive shaft. The other end of the reciprocating screw and the rotary drive shaft are movably connected and installed inside the bubble removal installation housing via a sealed bearing. One end of the rotary drive shaft is connected to a drive motor, and the drive motor housing is connected to the bubble removal installation housing.

[0009] Furthermore, a support frame is attached to the bottom of the housing to remove air bubbles.

[0010] Furthermore, a PLC controller is installed on one side of the support frame, and the PLC controller is electrically connected to the drive motor.

[0011] Furthermore, in order to achieve the function of feeding installation, the feeding installation component includes a feeding pipe, one end of which is connected to a material conveying pump, the input end of which is connected to an input pipe, and a feeding shut-off valve is installed inside the feeding pipe.

[0012] Furthermore, the material conveying pump and the feed shut-off valve are electrically connected to the PLC controller.

[0013] Furthermore, in order to achieve the function of material discharge installation, the material discharge installation component includes a material discharge pipe, a material discharge valve is installed inside the material discharge pipe, and an ultrasonic generator is provided on one side of the material discharge pipe. The ultrasonic generator is installed inside the material discharge pipe.

[0014] Furthermore, a flow sensor is installed inside the discharge pipe.

[0015] Furthermore, the discharge valve, ultrasonic generator, and flow sensor are electrically connected to the PLC controller.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) This utility model improves upon the existing technology. In actual use, by removing the bubble installation component, a single drive source is used to simultaneously perform debubbling of the filament pad and debubbling of the agitation, which solves the limitations of traditional debubbling methods, including vacuum debubbling, centrifugal debubbling and heating debubbling: vacuum debubbling requires the use of open containers and is prone to causing "false boiling" due to excessive vacuuming; centrifugal debubbling easily causes the filler to separate into layers in glues containing fillers, and the equipment operation is complicated; heating methods require strict temperature control to avoid accelerating the curing of the glue.

[0018] (2) In actual use, the processed material is discharged through the discharge pipe, and the discharge valve adjusts the opening according to the flow data fed back by the flow sensor; the ultrasonic generator breaks up the residual air bubbles in the discharge pipe for a second time to ensure that the finished product has no air bubbles.

Detailed Implementation

[0026] 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.

[0027] According to an embodiment of the present invention, an epoxy AB adhesive production bubble removal device is provided, including a bubble removal mounting shell 1, a bubble removal mounting assembly 2 inside the bubble removal mounting shell 1, a feeding mounting assembly 3 on one side of the bubble removal mounting assembly 2, and a discharging mounting assembly 4 on one side of the bubble removal mounting shell 1.

[0028] like Figure 1-4As shown, the epoxy AB glue production bubble removal device according to an embodiment of the present invention includes a bubble removal mounting assembly 2 comprising a reciprocating screw 201, a movable slider 202 surrounding the reciprocating screw 201, a wire pad mounting bracket 203 surrounding the movable slider 202, a nylon filter membrane 204 installed inside the wire pad mounting bracket 203, a limiting mounting plate 206 movably connected to the reciprocating screw 201, the limiting mounting plate 206 being connected to the bubble removal mounting housing 1, and a rotary drive shaft 207 connected to one end of the reciprocating screw 201. 7. A stirring rod 208 is connected to the outside. The other end of the reciprocating screw 201 and the rotary drive shaft 207 are movably connected and installed inside the deaerator housing 1 through a sealed bearing 209. One end of the rotary drive shaft 207 is connected to a drive motor 205. The housing of the drive motor 205 is connected to the deaerator housing 1. A support frame 5 is connected to the bottom of the deaerator housing 1. The support frame 5 serves to support the deaerator housing 1. A PLC controller 6 is installed on one side of the support frame 5. The PLC controller 6 is electrically connected to the drive motor 205.

[0029] Through the above technical solution, the drive motor 205 drives the reciprocating screw 201 to rotate via the rotary drive shaft 207, while simultaneously driving the stirring rod 208 to mix the material. The rotational motion of the reciprocating screw 201 is converted into the linear reciprocating motion of the moving slider 202, which pushes the pad mounting bracket 203 and the nylon filter membrane 204 to move periodically under the constraint of the limiting mounting plate 206. When the nylon filter membrane 204 moves back and forth with the pad mounting bracket 203, it intercepts air bubbles in the material and crushes them. The stirring rod 208 rotates synchronously, enhancing the fluidity of the material and assisting in the separation of air bubbles. The reciprocating screw 201 and the rotary drive shaft 207 are installed inside the air bubble removal mounting housing 1 through the sealed bearing 209, ensuring the sealing between the moving parts and the housing and preventing material leakage.

[0030] Among them, nylon 204 filter membrane (PA66 material) has broad chemical compatibility, can withstand dilute acids, dilute alkalis and organic solvents (such as alcohols, hydrocarbons, esters, etc.), and has good compatibility with common components in AD adhesives such as epoxy resins and acrylates, avoiding deterioration of the adhesive due to chemical reactions. The pore size range of nylon 204 filter membrane is 0.01-10μm. For micron-sized bubbles (usually ≥0.1μm) in AD adhesives, selecting a filter membrane with a pore size of 0.2-0.45μm can effectively intercept bubbles while maintaining the flow rate of the adhesive (e.g., a water flow rate of 15-20mL / min / cm with a 0.45μm filter membrane). 2 ).

[0031] It is worth noting that the nylon filter membrane 204 in this application is suitable for situations where the AB glue concentration is low (fast-drying acrylic glue). At the same time, the stirring speed should not be too fast. When using it, the inside of the housing 1 should be evacuated to remove air bubbles to avoid the generation of secondary air bubbles. After stirring, let it stand for 8-10 minutes before discharging.

[0032] like Figure 1-4 As shown, in the epoxy AB glue production bubble removal device according to the embodiment of this utility model, the feeding installation assembly 3 includes a feeding pipe 301, one end of which is connected to a material conveying pump 302, the input end of which is connected to an input pipe 303, and a feeding shut-off valve 304 is installed inside the feeding pipe 301. The material conveying pump 302 and the feeding shut-off valve 304 are electrically connected to the PLC controller 6.

[0033] Through the above technical solution, the material enters the material conveying pump 302 through the input pipe 303, and is conveyed to the inside of the air bubble removal installation shell 1 through the feed pipe 301. The feed stop valve 304 is controlled by the PLC controller 6 to open and close, and the feed amount is precisely adjusted.

[0034] like Figure 1-4 As shown, in the epoxy AB glue production bubble removal device according to an embodiment of the present invention, the discharge installation assembly 4 includes a discharge pipe 401, a discharge valve 402 installed inside the discharge pipe 401, an ultrasonic generator 403 provided on one side of the discharge pipe 401, the ultrasonic generator 403 installed inside the discharge pipe 401, and a flow sensor 7 installed inside the discharge pipe 401. The discharge valve 402, the ultrasonic generator 403 and the flow sensor 7 are electrically connected to the PLC controller 6 respectively.

[0035] Through the above technical solution, the processed material is discharged through the discharge pipe 401, and the discharge valve 402 adjusts the opening according to the flow data fed back by the flow sensor 7; the ultrasonic generator 403 performs secondary crushing of the residual air bubbles in the discharge pipe 401 to ensure that the finished product has no air bubble residue.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
