Description

Technical Field

[0001] The utility model relates to the technical field of SMC sheet production equipment, in particular to a folding and rolling mechanism for SMC sheet molding material. Background Art

[0002] SMC is a type of sheet molding material made of resin paste impregnated fibers or chopped fiber mats covered with polyethylene film on both sides. It has the properties of electrical insulation, heat resistance, flame retardancy, good mechanical strength, etc., and is therefore widely used in industries such as transportation vehicles. During the production process, it will be folded, rolled and stored through a winding mechanism.

[0003] In the prior art, the SMC sheet molding compound folding and winding mechanism collects the folded and fallen sheets through a collecting box, but the position of the collecting box needs to be manually positioned. Some winding machines use a positioning mechanism for positioning. For example, an SMC sheet molding compound folding and winding mechanism with publication number CN202221200217.3, although it can position the collecting box, the front and rear positions of the collecting box are not automatically positioned, resulting in a large deviation in the front and rear directions of the collecting box. The sheets cannot be normally stored in the collecting box, and the collecting box needs to be manually pushed back and forth in the winding frame, which is very troublesome. Therefore, it is necessary to design an SMC sheet molding compound folding and winding mechanism to solve the above problems. Utility Model Content

[0021] Reference Figure 1-3 , a SMC sheet molding compound folding and winding mechanism, including a first mounting frame 1 and a winding frame body 7, the winding frame body 7 is a winding frame in the prior art, and its working principle is not described in detail. The upper end of the first mounting frame 1 is fixedly connected to a mounting frame 5, and the mounting frame 5 is provided with a first positioning mechanism for positioning the position of the SMC sheet material collection box. The first positioning mechanism includes two sliding frames 14 slidably connected to the top of the mounting frame 5, and a double-headed screw 3 is rotatably connected to the mounting frame 5, and a hand wheel 13 is fixedly connected to one end of the double-headed screw 3. A first conveyor belt 2 is provided in the first mounting frame 1, and a first motor 6 is provided on the side wall of the first mounting frame 1. The first motor 6 can be a Siemens servo motor with a model of 1FK7101-2AC71-1RH1. The output shaft speed of the first motor 6 is adjustable, and the moving speed of the collection box can be controlled.

[0022] A second positioning mechanism for positioning the SMC sheet material collection box is provided in the winding frame body 7. The second positioning mechanism includes a fixed frame 10 fixedly connected to the inner wall of the winding frame body 7. A reciprocating screw 11 is rotatably connected to the inner wall of the fixed frame 10. A positioning plate 8 and a turntable 17 are provided on the reciprocating screw 11.

[0023] In the utility model, a second motor 9 is fixedly connected to the side wall of the winding frame body 7, and one end of the reciprocating screw 11 close to the second motor 9 is fixedly connected to the output shaft of the second motor 9. The second motor 9 can be an external drive screw integrated stepper motor with model SPS86E276-5.08-150, which does not require manual rotation of the hand wheel 13, thereby improving the degree of automation of the device.

[0024] In the utility model, the side wall of the mounting frame 5 is fixedly connected to the third motor 12, and the other end of the double-headed screw 3 is fixedly connected to the output shaft of the third motor 12. The third motor 12 can be a servo motor with model 130ZFMA1-0003CBNM, and its output shaft can be rotated forward and reversely. The control mode is one of the following: pulse control mode, analog control mode, and communication control mode. There is no need to manually rotate the hand turntable 17, thereby improving the degree of automation of the device.

[0025] In the utility model, a plurality of guide rollers 4 are provided on the inner wall of the sliding frame 14, and the plurality of guide rollers 4 are arranged at equal intervals, so that when the collecting box is close to the collecting box, the first conveyor belt 2 will not be affected and the collecting box does not need to be pushed completely onto the first conveyor belt 2 manually.

[0026] In the utility model, a second mounting frame 18 is fixedly connected to the side wall of the first mounting frame 1, a second conveyor belt 15 is provided in the second mounting frame 18, a fourth motor 16 is installed on the side wall of the second mounting frame 18, and the fourth motor 16 can be a Siemens servo motor with model 1FK7101-2AC71-1RH1. The output shaft speed of the first motor 6 is adjustable, and the moving speed of the collection box can be controlled.

[0027] In the initial state, the collection box is not on the first conveyor belt 2.

[0028] When in use, place the collection box on the first conveyor belt 2, push it into the mounting frame 5, turn the hand wheel 13, so that the two sliding frames 14 move toward each other to push the collection box to the center of the first conveyor belt 2, and then start the first motor 6. The output shaft of the first motor 6 drives the first conveyor belt 2 to rotate, and the first conveyor belt 2 automatically transports the collection box to the bottom of the winding frame body 7. During the process, the collection box can be automatically positioned and input, and there is no need to worry about the misalignment of the collection box placement direction causing the sheet material to not be completely folded into the collection box, and it also avoids the action of manual correction;

[0029] Secondly, for the collection box under the winding frame body 7, it is not necessary to manually block it. By rotating the turntable 17, the reciprocating screw 11 rotates, and the L-shaped positioning plate 8 moves to the center of the first conveyor belt 2 to block the collection box from moving forward. The reciprocating screw 11 is reversed, and the L-shaped positioning plate 8 is reinserted into the side wall of the winding frame body 7 without affecting the movement of the collection box.

[0030] In addition, after the collection box is collected, the first motor 6 and the fourth motor 16 can be started, and the first conveyor belt 2 and the second conveyor belt 15 can rotate. After the collection box moves to the second conveyor belt 15, it can be automatically moved out from under the winding frame body 7, and it is convenient for the collection box to unload and the other collection box to load.
