Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber prepreg processing equipment, in particular to a novel glue dipping device for a prepreg machine. Background Art

[0002] After the surface treatment, carbon fiber needs to be glued, which is used to protect the surface activity of carbon fiber after surface treatment and enhance the bonding strength between carbon fiber and matrix resin. The glue forms a smooth and tough film on the surface of the filaments and fibers, improves wear resistance, prevents the generation of hair, and maintains the original elasticity. The glue penetrates into the fiber and glues part of the fiber to increase the cohesion. At present, there are two main processes for the production of thermosetting resin matrix carbon fiber prepregs at home and abroad: solution impregnation and hot melt. The advantage of the solution impregnation method is that the reinforcing material is easily impregnated by the resin matrix; thin prepregs can be manufactured, and thick prepregs can also be manufactured; the equipment cost is relatively low. The disadvantage is that a drying furnace is required to remove the solvent or recover the solvent. Improper handling can cause combustion or environmental pollution; prepregs often have a certain amount of solvent remaining, which is easy to form voids during molding, affecting the performance of composite materials. The advantages of hot melt impregnation are high process speed and high efficiency; easy to control resin content; no solvent, low volatile content of prepreg, safe process; no need for drying furnace, reduced environmental pollution; film making and impregnation process can be carried out in steps, reducing the loss of materials, especially expensive reinforcement materials; and the appearance quality of prepregs made by this process is also good. Disadvantages are that thick prepregs, especially fabrics, are difficult to impregnate, high viscosity resins are difficult to impregnate, the amount of release paper and PE film is large, and currently only one-sided impregnation can be achieved, which cannot meet actual needs. These two process methods have their own advantages and disadvantages, but the overall production efficiency is relatively low.

[0045] The glue melting device is two groups of heating panels 12, which are symmetrical and tilted downward into the glue dipping pool; a heating cover is installed at the bottom of the heating panel 12 to heat the colloid inside the heating panel 12, and the two glues or one glue that need to be mixed can be heated and melted separately, and then flow out from the glue outlet at the bottom of the heating panel 12, enter the glue dipping pool for effective mixing, and perform one-step glue dipping, extrusion, and cloth discharging in real time. The operation is convenient, time-saving and labor-saving, and the use of hot melt glue is significantly reduced. The thickness of the colloid is accurately controlled according to actual needs. A heating filter screen plate 13 matching it is installed at the glue outlet at the bottom of the heating panel 12 to further control the liquid outflow quality of the hot melt glue, prevent the outflow of foreign matter or unmelted particles, and ensure that the glue dipping process is continuously and effectively carried out.

First of all, ensure that the relative position between the front and rear rubber baffle plates 4 is fixed during use to prevent lateral deviation, and can effectively control the seamless connection between the bottom of the rubber baffle plate 4 and the active glue dipping heating roller 2 and the driven glue dipping heating roller 3 to prevent glue overflow; at the same time, it can also realize that as the relative position between the active glue dipping heating roller 2 and the driven glue dipping heating roller 3 changes, the seamless connection between the bottom of the rubber baffle plate 4 and the active glue dipping heating roller 2 and the driven glue dipping heating roller 3 can be timely and effectively controlled.

[0047] A pad is provided at the bottom of the glue blocking plate 4, which is made of polytetrafluoroethylene; the upper surfaces of the active glue dipping heating roller 2 and the driven glue dipping heating roller 3 are made of smooth steel.

Two sets of parallel second guide rollers 25 and third guide rollers 26 are connected to the bottom surface of the top frame of the upper frame 14, respectively. The center lines of the active dipping and heating roller 2 and the driven dipping and heating roller 3 are arranged parallel to the third guide roller 26; the first guide roller 24 and the second guide roller 25 are arranged on the outer side and the inner side of the vertical frame of the upper frame 14 on the same side, respectively. A fourth guide roller 27 is also arranged at the bottom of the platform bracket, and the fourth guide roller 27 is arranged on the right side of the driven dipping and heating roller 3. The four guide rollers control the feed position, feed angle, and the relative position relationship between the feed and the hot melt adhesive device, so as to achieve accurate and effective control of parameters such as the dipping amount, dipping thickness, and dipping type, and have a wide range of applications.

[0052] The specific usage process is:

[0053] The utility model provides a novel glue dipping device for a prepreg machine. The glue dipping rollers move laterally, and the gap between the two glue dipping rollers is adjusted by a servo motor to control the amount of hot melt adhesive entering the glue dipping pool.

[0055] like Fig. 9As shown, when the feed material passes through the second guide roller 25 and the third guide roller 26 located on the bottom surface of the top frame of the upper frame 14, it passes through the two pressure rollers vertically from the center of the active dipping and heating roller 2 and the driven dipping and heating roller 3, and then comes out in the horizontal direction, the effect is achieved: the purpose of double-sided dipping can be achieved.

[0056] like Figure 8 As shown, when the feed material passes through the second guide roller 25 and the third guide roller 26 located on the bottom surface of the top frame of the upper frame 14, it passes through the two pressure rollers vertically from the center of the active dipping and heating roller 2 and the driven dipping and heating roller 3, and then passes through the fourth guide roller 27 below, and then the cloth is discharged in the horizontal direction, the effect is achieved: reducing the wrap angle when the cloth is discharged, so as to achieve the effect of double-sided dipping and reducing the contact area.
