The plurality of guide rollers guide the fiberglass cloth to be sequentially conveyed through the solvent pre-impregnation tank, the thin adhesive pre-impregnation tank, the impregnation tank, and the permeation tank. At least one degassing roller assembly for rolling the fiberglass cloth is respectively arranged in the thin adhesive pre-impregnation tank and the impregnation tank. The permeation tank is surrounded by a saturation zone and a permeation zone, and the saturation zone is connected to one end of an adhesive injection pipe for injecting adhesive solution into the saturation zone. The fiberglass cloth output from the impregnation tank passes through the permeation tank, and both sides of the fiberglass cloth are located in the saturation zone and the permeation zone, respectively.

[0003] Chinese Patent Publication No. CN201880663U discloses an impregnation device, comprising: a main body, a first floating roller and a second floating roller mounted on the main body, a pre-impregnation roller mounted on the main body, an adhesive tray, an adhesive spraying device, and an adhesive scraping device. The pre-impregnation roller is disposed between the first and second floating rollers. The adhesive tray is disposed below the first floating roller and between the first floating roller and the pre-impregnation roller. The adhesive spraying device is disposed above the space between the pre-impregnation roller and the second floating roller. The adhesive scraping device includes a scraper disposed below the space between the pre-impregnation roller and the second floating roller, and a scraping roller disposed on the side of the second floating roller opposite to the pre-impregnation roller. This impregnation device features multiple scraping and extrusion impregnation processes. Furthermore, by adjusting the position of the floating rollers, the extrusion contact area between the reinforcing material and the adhesive can be increased, resulting in more thorough extrusion and impregnation of the reinforcing material and the adhesive, and a continuous and uniform impregnation effect. The prepreg produced using this invention reduces air bubbles between the reinforcing material and the prepreg adhesive, improving the surface quality of the produced copper-clad laminate substrate.

[0004] However, existing dipping equipment has a simple structure, cannot control temperature and amount of adhesive, and has low working efficiency. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The implementation of this utility model will be described in detail below with reference to specific embodiments.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0022] like Figure 1-2 As shown, this utility model provides a temperature- and glue-volume controllable impregnation device, including a frame 1, a double-layer glue tank 2, a yarn guide roller 3, and a retaining roller assembly 4. The double-layer glue tank 2 is fixedly connected to the middle of the frame 1, the yarn guide roller 3 is rotatably connected to one end of the frame 1, and the retaining roller assembly 4 is installed at the end of the frame 1 away from the yarn guide roller 3. The detachable connection of the pressure roller bracket 5 facilitates quick replacement or maintenance of the pressure roller 6, reducing downtime and improving production efficiency; when the pressure roller 6 contacts the fiber, rolling friction replaces sliding friction, avoiding fiber damage and ensuring uniform glue penetration; the rigid connection design between the double-layer glue tank 2 and the frame 1 enhances overall vibration resistance and is suitable for high-speed continuous production scenarios.

[0023] The double-layer glue tank 2 is equipped with a pressure roller bracket 5 and a pressure roller 6. The pressure roller bracket 5 is detachably connected to both sides of the double-layer glue tank 2, and the pressure roller 6 is rotatably connected to the pressure roller bracket 5.

[0024] A recycling conduit 14 is installed at the bottom of the double-layer glue tank 2, and the recycling conduit 14 is connected to the external glue recycling tank.

[0025] The recycling conduit 14 guides the dripping adhesive to the recycling tank in real time, reducing adhesive waste and lowering production costs; it also prevents the adhesive from dripping directly onto the ground and causing pollution, meeting the requirements of green production; and by dynamically recycling the adhesive, it maintains a stable adhesive level in the double-layer adhesive tank 2, ensuring consistent adhesive impregnation.

[0026] The roller bracket assembly 4 includes a roller bracket 7, a fixed roller 9, a movable roller 10, a slider 11, a screw 12, and a handwheel 13. The roller bracket 7 is installed on the top of the frame 1. The fixed roller 9 is rotatably connected to the middle of the roller bracket 7. The slider 11 is slidably connected to the middle of the roller bracket 7. The screw 12 is rotatably connected to the top of the roller bracket 7. The bottom of the screw 12 is threadedly connected to the middle of the slider 11. The handwheel 13 is installed on the top of the screw 12.

[0027] The height of the moving roller 10 can be finely adjusted by the handwheel 13 to precisely control the amount of adhesive on the fiber (±0.1mm accuracy) and avoid excessive or insufficient adhesive. The threaded transmission structure of the screw 12 and the slider 11 enables a single person to complete the adhesive adjustment within a minute, improving process flexibility. The surface of the moving roller 10 is plated with hard chrome, which improves wear resistance by more than 3 times and is suitable for high-intensity continuous operation.

[0028] It also includes a guide plate 18, which is adjustablely mounted on the front end of the guide roller bracket 7 and the rear end of the guide roller 3. The transverse and longitudinal positions of the guide plate 18 are adjustable to accommodate different fiber widths (5-50mm) and prevent fiber deviation or entanglement; the edges of the guide plate 18 are rounded and polished to reduce frictional resistance when the fiber passes through, reducing the yarn breakage rate by more than 40%; it supports rapid switching production of multiple types of fibers (such as carbon fiber and glass fiber).

[0029] It also includes casters 15, fixed brackets 16 and fixed rods 17. The casters 15 are distributed at the four corners and rotatably connected to the bottom of the frame 1. The fixed brackets 16 are rotatably connected to the bottom of the frame 1, and the fixed rods 17 are rotatably connected to the middle of the fixed brackets 16.

[0030] The 15 casters support 360° rotation, allowing a single person to easily push the equipment in the workshop, saving transportation time; the fixed bracket 16 is pressed against the ground by the fixed rod 17 after landing, preventing displacement of the equipment during operation (resistance to offset force ≥500N), ensuring production accuracy; switching from mobile mode to fixed mode takes only 10 seconds, adapting to the needs of multi-station production.

[0031] The surface of the yarn guide roller 3 is coated with polytetrafluoroethylene to reduce fiber friction damage. A temperature control component, including a heating rod and a thermocouple, is located in the middle of the double-layer adhesive tank 2.

[0032] The PTFE coating has a friction coefficient of only 0.04, reducing resistance by 60% when fibers pass through, thus reducing fuzzing or breakage; it is resistant to solvents in the adhesive (such as acetone and epoxy resin), extending the service life of the guide roller 3 to more than 5 years; the heating rods are distributed and combined with real-time thermocouple feedback, controlling the temperature fluctuation of the adhesive within ±1℃, ensuring stable adhesive viscosity; the heating power is adjusted using a PID algorithm, reducing energy consumption by 25% compared to traditional heating methods;

[0033] Referring to the figure, a preferred embodiment of the present invention is provided.

[0034] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
