Description

Technical Field

[0001] This utility model relates to the field of SMC sheet plastic production technology, specifically to a pressure device for the impregnation section of an SMC sheet molding compound production unit. Background Technology

[0002] SMC, or sheet molding compound, is mainly composed of SMC special yarn, unsaturated resin, low-shrinkage additives, fillers, and various auxiliaries. SMC is a type of sheet molding compound made by impregnating fiber or chopped fiber felt with resin paste and covering both sides with a polyhexene film. It is widely used in transportation vehicles, construction, electronics, electrical and other industries.

[0003] In the existing technology, the existing SMC sheet molding compound impregnation and pressure device will carry away excess resin paste during long-term operation. At the same time, the existing impregnation and pressure device will not be heated evenly during the thickening process of the impregnated sheet molding compound, which will affect the winding of the sheet molding compound. To address this, we propose an impregnation section pressure device for an SMC sheet molding compound production unit. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a pressure device for the impregnation section of an SMC sheet molding compound production unit. This device facilitates the collection of resin paste, helps reduce resource waste, prevents uneven heating during thickening, and quickly thickens the resin paste to prevent excess residue. It can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure device for the impregnation section of an SMC sheet molding compound production unit, comprising a base plate, an impregnation unit, an extrusion unit, and a thickening unit;

[0006] Base plate: The upper end is equipped with an immersion unit;

[0007] Soaking unit: includes a soaking tank, a fixing frame, a snap-fit ​​groove, a snap-fit ​​block and a sponge. The soaking tank is fixedly connected to the upper front side of the base plate. The fixing frame is fixedly connected to the upper front end of the soaking tank. A snap-fit ​​groove is opened in the middle of the upper end of the fixing frame. A sponge is fixedly connected to the lower end of the snap-fit ​​block. The snap-fit ​​groove snaps into the snap-fit ​​block.

[0008] Extrusion unit: mounted on the base plate;

[0009] Thickening unit: mounted on the base plate.

[0010] The snap-fit ​​blocks are fixed by snap-fit ​​grooves, the surface dust is simply cleaned by a sponge, and resin paste is placed in the soaking tank to achieve rapid soaking.

[0011] Furthermore, the soaking unit also includes pressure sensors, limiting frames, rotating wheels, and fixed wheels. Two pressure sensors are fixedly connected to the lower left and right sides of the fixed frame. The lower ends of the pressure sensors are fixedly connected to the limiting frames, and rotating wheels are rotatably connected to the inner sides of the two limiting frames. Fixed wheels are correspondingly fixedly connected to the lower left and right sides of the soaking tank. The pressure sensors detect the tensile force on the sheet molding compound during soaking. The limiting frames limit the rotating wheels, and the fixed wheels allow the device to better soak and stretch the film, ensuring effective soaking of the sheet molding compound in the resin paste.

[0012] Furthermore, the extrusion unit includes a mounting frame, an electric telescopic rod, and a second rotating wheel. Two mounting frames are fixedly connected to the upper rear side of the soaking tank, and an electric telescopic rod is fixedly connected to the lower end of each mounting frame. The second rotating wheel is rotatably connected between the two electric telescopic rods. The mounting frames limit the movement of the electric telescopic rods, and the electric telescopic rods limit the movement of the second rotating wheel, thereby guiding the sheet molding compound.

[0013] Furthermore, the extrusion unit also includes a support frame, three rotating wheels, a motor, gears, and a flow guide plate. Two support frames are fixedly connected to the left and right ends of the upper center of the base plate, and two rotating wheels are rotatably connected between the two support frames. Gears are fixedly connected to the right end of each rotating wheel, and the two gears mesh. A motor is fixedly connected to the left end of each support frame, and the output shaft of the motor is fixedly connected to the left end of each rotating wheel. A flow guide plate is fixedly connected to the middle of the support frames, and the lower end of the flow guide plate is fixedly connected to the soaking tank. The height of the rotating wheels is limited by the support frames, and the rotating wheels extrude excess resin paste from the surface of the sheet molding compound. The excess paste flows back into the soaking tank through the flow guide plate. The motor drives the rotating wheels to rotate, and power is transmitted through the gears.

[0014] Furthermore, the thickening unit includes two support plates fixedly connected to the upper center of the base plate, with a heating box fixedly connected to the upper end of each support plate. A ventilation fan is fixedly connected to the upper end of the heating box. A rectangular plate is fixedly connected between the two support plates at the center, and a collection box is placed on the rectangular support plate. Guide wheels are rotatably connected to the upper ends of the support plates. The resin paste on the surface of the sheet molding compound is dried by the heating box, air circulation is ensured below the heating box by the ventilation fan, and the resin paste dripping from the sheet molding compound is collected by the collection box.

[0015] Furthermore, the system also includes a support mounting bracket, a take-up roller, a third motor, and a motor mounting bracket. Two support mounting brackets are fixedly connected to the upper rear side of the base plate, and a take-up roller is rotatably connected between the two support mounting brackets. A motor mounting bracket is fixedly connected to the right end of each support mounting bracket, and a third motor is fixedly connected to the upper end of the motor mounting bracket. The output shaft of the third motor is fixedly connected to the take-up roller. The support mounting brackets limit the movement of the take-up roller, and the third motor provides power for the rotation of the take-up roller, thereby ensuring that the sheet molding compound can be wound within the normal tension range.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The pressure application device of the impregnation section of this SMC sheet molding compound production unit has the following advantages:

[0017] 1. The pressure device in the impregnation section of this SMC sheet molding compound production unit can quickly remove excess resin paste during the production process. The excess resin paste on the surface of the sheet molding compound is squeezed by the three rotating wheels and flows back into the impregnation tank through the diversion plate, thereby facilitating the collection of resin paste and reducing waste of resources.

[0018] 2. The pressure device in the impregnation section of this SMC sheet molding compound production unit thickens the resin paste on the surface of the sheet molding compound through a thickening device. A ventilation fan ensures air circulation inside the thickening device to prevent uneven heating during thickening and quickly thicken the resin paste to prevent excess residue.

Simultaneously, the resin paste is placed in the impregnation tank 31, achieving rapid impregnation. The pressure sensor 36 detects the tension on the sheet molding compound during impregnation. The limiting frame 37 limits the rotation wheel 38, and the fixed wheel 39 allows for better impregnation and stretching of the film, ensuring effective impregnation of the sheet molding compound in the resin paste. The mounting frame 41 limits the electric telescopic rod 42, which in turn limits the rotation wheel 43, guiding the sheet molding compound.
