Description

Technical Field

[0001] This utility model relates to the technical field of impregnation treatment, and particularly to an impregnation treatment system. Background Technology

[0002] Impregnation is used in the surface coating process of films such as glass fiber or carbon fiber. It involves coating a roll of film with a specific functional adhesive, coating, paint, or ink, drying it, and then rewinding it. During the coating process, the film, such as glass fiber or carbon fiber, is driven forward by a feeding mechanism. Multiple rollers with different purposes are used to achieve feeding, removal of excess adhesive, coating, paint, or ink, or cooling.

[0003] In most impregnation systems, rollers are secured in place using connecting bearings. If impregnating liquids such as adhesives, coatings, paints, or inks enter the impregnation process and are not properly drained, it can cause the rollers to malfunction, leading to various quality problems such as uneven coating and wrinkles. In such cases, personnel often have to repair or replace the connecting bearings. Replacement requires repositioning, which is troublesome, time-consuming, and increases labor costs.

[0004] Furthermore, improper surface friction of the impregnation rollers or cooling rollers can cause wrinkles in the material (e.g., irregularly distributed wrinkles along the direction of travel), which can affect subsequent winding and the overall quality of the product. Moreover, uneven temperature during drying and cooling after impregnation can often result in defects such as false drying (the surface is dry but the interior is not), or cracking, thus affecting product quality.

[0005] In summary, the inventor of this utility model has conceived and designed an impregnation treatment system in order to improve upon the shortcomings of the prior art and thereby enhance its industrial application. Utility Model Content

[0032] Please refer to the following: Figures 1 to 5 . Figure 1 This is a schematic diagram of the overall structure of the impregnation treatment system of this utility model. Figure 2 This is a schematic diagram of the impregnation treatment module of the impregnation treatment system of this utility model. Figure 3 This is a schematic diagram of the metering roller in the impregnation treatment system of this utility model. Figure 4 This is a schematic diagram of the cooling air box module of the impregnation treatment system of this utility model. Figure 5 This is a schematic diagram of the structure of the cooling fabric spreading module of the impregnation treatment system of this utility model.

[0033] As shown in the figure, the impregnation treatment system S of this utility model mainly includes an impregnation treatment module 1, a heating module 2, a cooling air box module 3, and a cooling cloth spreading module.

[0034] In this process, substrate B is conveyed to the impregnation module 1 along the first direction D1. Incidentally, the impregnation system S of this invention includes a decoupling machine, on which a substrate B is wound, and which decouples the substrate B for conveying to the impregnation module 1. Furthermore, the first direction D1 can be a transverse direction, and the substrate B is conveyed to the impregnation module 1 along the first direction D1, which can be parallel to the first direction D1 or at a predetermined angle to the first direction D1, but the substrate B is generally still conveyed along the first direction D1.

[0035] Furthermore, the impregnation processing module 1 includes an impregnation tank 11, at least one upper impregnation roller 12, and at least one lower impregnation roller 13. The impregnation tank 11 stores an impregnation solution; the impregnation processing module 1 uses the impregnation solution to impregnate the substrate B; wherein the impregnation solution is, for example, an epoxy resin solution. The upper impregnation roller 12 is located above the surface of the impregnation solution, and the lower impregnation roller 13 is located at or below the surface of the impregnation solution; wherein, the lower impregnation roller 13 is located at the surface of the impregnation solution, for example, the lower impregnation roller 13 is partially below the surface and partially above the surface.

[0036] It is worth mentioning that a metering roller 14 is provided between the impregnation treatment module 1 and the heating module 2. The distance between the two metering rollers 14 corresponds to the thickness of the substrate B, and the two metering rollers 14 can appropriately retract to create a gap when facing the fabric end. There is a vertical distance H between the liquid surface of the impregnation tank 11 and the metering roller 14. This vertical distance H is configured according to different impregnation solutions; for example, when the impregnation solution is epoxy resin, the vertical distance H can be 150 mm. Therefore, the impregnation treatment system S of this invention adjusts the vertical distance H between the impregnation tank 11 and the metering roller 14 based on different impregnation properties, thereby achieving good impregnation treatment with a uniform coating effect and the expected thickness and resin content stability.

[0037] The heating module 2 is located on the output side of the impregnation treatment module 1. The substrate B after impregnation treatment is transported from the impregnation treatment module 1 to the heating module 2. In the heating module 2, the substrate B is transported along a second direction D2 that is perpendicular to the first direction D1; that is, the second direction D2 is a vertical direction.

[0038] Furthermore, the heating module 2 may include multiple heating mechanisms to heat the substrate B and the impregnation solution on the substrate B. The heating module 2 has an input path 21 and an output path 22. One end of the input path 21 is connected to the impregnation treatment module 1, and the other end is connected to the cooling air box module 3, which is connected to the cooling fabric spreading module 4. The cooling fabric spreading module 4 is then connected to the cooling air box module 3, which is connected to the output path 22. Incidentally, the other end of the output path 22 may be connected to a cooling roller and an edge trimming machine, etc.

[0039] The cooling air box module 3 includes a first cooling air box 31 and a second cooling air box 32. The first cooling air box 31 is located between the other end of the input path 21 and the cooling cloth laying module 4. The second cooling air box 32 is located between the cooling cloth laying module 4 and one end of the output path 22.

[0040] It is worth mentioning that the first cooling air box 31 and the second cooling air box 32 each include multiple sets of nozzle groups 33. These multiple sets of nozzle groups 33 are arranged along the second direction D2, and the number of multiple sets of nozzle groups 33 in the first cooling air box 31 is greater than the number of multiple sets of nozzle groups 33 in the second cooling air box 32. Optionally, the number of multiple sets of nozzle groups 33 in the first cooling air box 31 is at least two more sets than the number of multiple sets of nozzle groups 33 in the second cooling air box 32. Furthermore, each nozzle group 33 includes two nozzles 331 arranged at intervals and symmetrically, with one nozzle orifice 332 of each nozzle 331 facing each other. The nozzle orifice 332 of each nozzle 331 forms an angle with the second direction D2; the angle can be, for example, 30 degrees, 45 degrees, or 60 degrees.

[0041] The impregnation treatment system S of this utility model, through the predetermined structural configuration of the cooling box module 3, can appropriately dry and cool the substrate B and the impregnation solution on it, so as to avoid false drying or drying defects such as cracking, and uniform cooling to prevent the substrate from sticking and wrinkling on the top roller.

[0042] It is worth mentioning that, of the two metering rollers 14, one metering roller 14 is made of special steel, while the other roller 14 can be made of tungsten carbide. Optionally, the surface of the metering roller 14 made of tungsten carbide has a high-hardness and ultra-wear-resistant antistatic layer 141. Thus, the impregnation treatment system S of this invention can avoid the problem of uneven impregnation.

[0043] The cooling fabric spreading module 4 is located between the other end of the input path 21 and one end of the output path 22. The substrate B is conveyed from the heating module 2 to the cooling fabric spreading module 4, which includes multiple cooling fabric spreading rollers 41. Optionally, the surface of the cooling fabric spreading rollers 41 is provided with a plasma layer 42. Thus, the impregnation treatment system S of this invention can avoid wrinkling and prevent the substrate from sticking due to insufficient cooling. Incidentally, the other end of the output path 22 can be connected to the cooling rollers and an edge trimming machine, and the cooling rollers can also utilize the plasma layer 42.

[0044] Please refer to the following: Figures 6 to 8 . Figure 6 This is an exploded structural diagram of the bearing housing of the impregnation treatment system of this utility model. Figure 7 This is a schematic diagram of the combined structure of the bearing housing of the impregnation treatment system of this utility model. Figure 8 This is a cross-sectional structural diagram of the bearing housing of the impregnation treatment system of this utility model. Figure 9 This is a schematic diagram illustrating the application of the bearing housing in the impregnation treatment system of this utility model.

[0045] As shown in the figure, one or both of the upper impregnation roller 12 and the lower impregnation roller 13 are disposed in a bearing housing 15 having a predetermined structure; optionally, the lower impregnation roller 13 is disposed in the bearing housing 15 having a predetermined structure.

[0046] Furthermore, the bearing housing 15 includes a bearing 151 and a base 152. The bearing 151 can be a bearing known or commonly used by those skilled in the art, such as a precision ball bearing; the bearing 151 is fixed to the connecting shaft of the roller, such as the connecting shaft of the lower impregnated roller 13. The bearing 151 is fixed to a roller connecting shaft, and the base 152 includes a first base 153 and a second base 154 that are detachably assembled as a whole. The first base 153 and the second base 154 each have a half-receiving groove 155, and when the first base 153 and the second base 154 are combined, the two half-receiving grooves 155 form a bearing chamber 156 that can accommodate the bearing 151. One of the first base 153 and the second base 154 has a communicating groove 157. In this embodiment, the second base 154 having a communicating groove 157 is used as an example. The connecting groove 157 is connected to the semi-accommodating groove 155 from the outer side of the first base 153 or the second base 154 in the radial direction, and the connecting groove 157 corresponds to the direction of gravity.

[0047] It is worth mentioning that the connecting channel 157 is an elongated elliptical shape. Incidentally, the axial direction is perpendicular to the direction of gravity, the radial direction is perpendicular to the axial direction, and there is an arbitrary angle between the radial direction and the direction of gravity.

[0048] Furthermore, the semi-circular receiving groove 155 has a diameter corresponding to the diameter of the bearing 151, thus the bearing housing 156 is also approximately circular with a diameter corresponding to the diameter of the bearing 151. The semi-circular receiving groove 155 includes a semi-annular positioning groove 158, and the bearing 151 has a semi-annular positioning protrusion 159 corresponding to the semi-annular positioning groove 158. Optionally, the bearing 151 has the semi-annular positioning protrusion 159, and the semi-circular receiving groove 155 has the semi-annular positioning groove 158 corresponding to the semi-annular positioning protrusion 159. Therefore, the bearing 151 can be appropriately and securely positioned in the bearing housing 156.

[0049] Furthermore, the first base 153 and the second base 154 can be made of metal, and their structures are largely the same except for the connecting groove 157. Each base includes a semi-disc portion, a semi-pillar portion, and two radial portions. The semi-pillar portion is located at the center point of the semi-disc portion and extends axially. The two radial portions are symmetrically arranged about the center point of the semi-disc portion and extend axially; in this embodiment, the extending direction of the radial portions forms a 90-degree angle with the direction of gravity.

[0050] The semi-accommodating groove 155 is disposed in the half-shaft column portion. The semi-disc portion is provided with multiple fixing holes, allowing the user to use the fixing holes to position the bearing seat 15 in a desired predetermined position. Each of the two radial portions is provided with an assembly portion; optionally, the assembly portion can be a through hole and a threaded hole, for example, the assembly portion of the first base 153 is a through hole, while the assembly portion of the second base 154 is a threaded hole, so that the user can use a bolt to pass through the through hole and lock it into the threaded hole to make the first base 153 and the second base 154 stably connected.

[0051] The impregnation treatment system of this utility model utilizes a bearing housing formed by the above-mentioned predetermined structure. When an impregnation liquid such as glue, coating, paint or ink is impregnated into the bearing housing, the impregnation liquid can be discharged through a connecting channel, thereby improving the problem of poor operation of the bearing housing caused by the impregnation liquid.

[0052] The above description is merely illustrative and not restrictive. Any equivalent modifications or alterations made without departing from the spirit and scope of this utility model should be included in the appended claims.
