[0002] A gluing machine is a device that can perform glue dipping on the surface of fabrics (cotton fiber, glass fiber, carbon fiber, polyester fiber, etc.). In the process of gluing the fabrics, a single wet dipping followed by drying is generally used. However, some products require composite resin dipping. The fluidity of the composite resin is poor at low temperatures, which results in poor dipping results. Traditional gluing machines drip glue onto a roller brush and evenly spread the glue on the fabric by rotating the roller brush, but are unable to achieve gluing of fabrics of different thicknesses. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of the utility model is to provide a solvent-free hot-melt gluing system, which can be realized by providing a temperature-adjustable heating shaft at the gluing location, so that the fabric is softened after the surface of the heating shaft is instantaneously heated. At this time, the hot-melt resin and the fabric are fully integrated to ensure the gluing quality.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A solvent-free hot melt gluing system comprises a support frame and a glue brush roller, the top of the support frame is provided with a traction roller, the top of the support frame is provided with a drying box, and columns are symmetrically arranged on both sides of the top of the support frame, the columns are placed on one side of the feeding end of the drying box, a heating shaft is arranged between the two columns, a heat conduction sleeve is rotatably installed on the surface of the heating shaft, a hot melt resin box is arranged on the top of the two columns, the top of the hot melt resin box is open, a glue outlet is arranged at the bottom of the hot melt resin box, a flow control valve is evenly installed on the inner side of the glue outlet, a slide groove is arranged above the side where the two columns are close to each other, a slider is vertically slidably installed inside the slide groove, the glue brush roller is placed parallel to the heat conduction sleeve, extension shafts are symmetrically arranged at both ends of the glue brush roller, the two extension shafts are respectively installed on the slider through bearings, the glue brush roller is placed directly below the glue outlet, and the fiber cloth runs through between the glue brush roller and the heat conduction sleeve.

[0006] Furthermore, a spring is arranged inside the slide groove, and the bottom of the spring contacts the upper surface of the slide block.

[0007] Furthermore, sleeves are installed on the surfaces of the two extension shafts through bearings, and discharge guide grooves are arranged on the tops of the two sleeves. The discharge guide grooves are placed parallel to the tops of the glue brushing rollers, and the tops of the discharge guide grooves slide below the inner side of the glue outlet.

[0008] Furthermore, a stirring roller is installed at the lower inner side of the hot melt resin box.

[0009] Furthermore, a box cover is flip-mounted at the open top of the hot-melt resin box.

[0010] Furthermore, the support frame is provided with a guide roller, and the guide roller is placed on a side of the hot melt resin box away from the drying box.

[0011] Compared with the prior art, the utility model has the following beneficial effects: when composite resin dipping is required, the conductive sleeve can be heated by the heating shaft to soften the gluing area of ​​the fabric, and the hot-melt resin and the fabric are fully integrated to ensure the gluing quality. At the same time, the brush roller above can adapt to the gluing work of fabrics of different thicknesses to ensure the contact strength between the brush roller and the surface of the fabric. At the same time, when gluing fabrics of different thicknesses, the height change of the brush roller can drive the discharge guide groove on its top to move up and down, so that the actual discharge port is consistent with the height of the brush roller, thereby ensuring the consistency of gluing.

It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] Please refer to Figure 1 and Figure 2 As shown, a solvent-free hot melt gluing system includes a support frame 1 and a glue brush roller 15, a traction roller 2 is arranged on the top of the support frame 1, a drying box 3 is fixedly arranged on the top of the support frame 1, and the glued cloth passes through the drying box for drying, columns 4 are symmetrically arranged on both sides of the top of the support frame 1, and the columns 4 are placed on one side of the feeding end of the drying box 3, a heating shaft 9 is arranged between the two columns 4, and a heat conduction sleeve 10 is rotatably installed on the surface of the heating shaft 9, and the heat conduction sleeve 10 can be heated by the heating shaft 9, and the heating range is (adjustable from 20 to 200°C), and the heat conduction sleeve 10 can rotate with the movement of the cloth, and a hot melt resin box 6 is arranged on the top of the two columns 4, and the hot melt resin box 6 has a heat preservation effect. The top of the hot melt resin box 6 is open, which is convenient for adding raw materials. A box cover 7 is flip-mounted at the top opening of the hot melt resin box 6 to seal the top opening, and a stirring roller 8 is installed at the lower inner side of the hot melt resin box 6, and the stirring roller 8 is driven by a motor to rotate to stir the glue inside the bottom.

[0021] Please refer to Figure 2-Figure 5 As shown, a glue outlet 61 is provided at the bottom of the hot melt resin box 6, and flow control valves 62 are evenly installed inside the glue outlet 61. The flow control valves 62 can be controlled individually. The glue output can be controlled by adjusting the flow control valves 62. When the cloth is narrow, the flow control valves 62 on both sides can be closed. A slide groove 11 is provided above the side where the two columns 4 are close to each other, and a slider 12 is vertically slidably installed inside the slide groove 11. A glue brush roller 15 is placed parallel to the heat transfer sleeve 10. The cloth passes between the glue brush roller 15 and the heat transfer sleeve 10, and the movement of the cloth drives the two to rotate. Extension shafts 14 are symmetrically arranged at both ends of the glue brush roller 15. The two extension shafts 14 are respectively installed on the slider 12 through bearings. The glue brush roller 15 is placed directly below the glue outlet 61, and then the height of the slider 12 is used to control the distance between the glue brush roller 15 and the heat transfer sleeve 10 to adapt to different cloths.

[0022] Among them, a spring 13 is arranged inside the slide groove 11, and the bottom of the spring 13 contacts the upper surface of the slider 12. The elastic force of the spring 13 is used to ensure that the slider 12 always has a downward force, thereby ensuring that the rubber brush roller 15 maintains contact with the cloth passing below.

[0023] Please refer to him 3- Figure 5The surfaces of the two extension shafts 14 shown are equipped with sleeves 16 through bearings, and the tops of the two sleeves 16 are provided with discharge guide grooves 17, which are placed parallel to the top of the glue brush roller 15, and a glue discharge gap is left between the discharge guide grooves 17 and the glue brush roller 15. The tops of the discharge guide grooves 17 slide underneath the inner side of the glue outlet 61, so that the discharge guide grooves 17 will not affect the rotation of the glue brush roller 15. The discharge guide grooves 17 are through grooves, and no matter how thick the fabric is or at what height the glue brush roller 15 is, the gap between the actual discharge and the glue brush roller 15 remains fixed to ensure the consistency of gluing.

[0024] Please refer to Figure 1 As shown, the support frame 1 is provided with a guide roller 5, and the guide roller 5 is placed on the side of the hot melt resin box 6 away from the drying box 3 to ensure the angle when brushing the glue.

[0025] The working principle of the utility model is as follows: the glue-free fiber is sequentially passed through the guide roller 5, the glue brush roller 15 and the heat conduction sleeve 10, the drying box 3 and the traction roller 2, and the fiber cloth is moved by the traction of the traction roller 2. Due to the presence of the springs 13 on both sides, the two sliders 12 have a downward thrust, and then the glue brush roller 15 can contact the surface of the fiber cloth passing below. Therefore, in the process of pulling the cloth to move, the glue brush roller 15 can be driven to rotate to adapt to the gluing work of fiber cloths of different thicknesses. According to the width of the cloth, The flow control valve 62 at different positions is adjusted to determine whether to discharge glue, or the amount of glue discharged by the flow control valve 62 is adjusted. The resin glue flows out through the flow control valve 62 and is guided by the discharge guide groove 17 to flow to the surface of the glue brush roller 15, and then the cloth passing below is glued. The heating shaft 9 can heat the heat conduction sleeve 10, so that the heat conduction sleeve 10 is kept in a high temperature state during the rotation process, so that the cloth is softened, and then the coated hot-melt resin is fully fused with the prepreg and sent to the gluing machine oven for secondary heat treatment to form the final prepreg.

[0026] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
