Description

Technical Field

[0001] The utility model relates to a cutting mechanism, in particular to an SMC sheet cutting mechanism, and belongs to the technical field of cutting mechanisms. Background Art

[0002] Sheet molding compound is abbreviated as SMC, which means sheet molding compound. SMC is a type of sheet molding compound made of resin paste impregnated fiber or chopped fiber mat covered with polyethylene film on both sides. It is generally composed of three categories: synthetic resin, reinforcing material and auxiliary material. The synthetic resin is unsaturated polyester resin, the reinforcing material is chopped fiber coarse sand or raw silk, and the auxiliary materials include curing agent (initiator), surface treatment agent, thickener, low shrinkage additive, release agent, colorant, filler and cross-linking agent. The role of the cross-linking agent in the initial batching is similar to that of a diluent, but the cross-linking agent participates in the curing reaction of the resin, thereby adjusting the performance of the product. When using sheet molding compound, it is usually necessary to equip it with a cutting mechanism to cut it into the required length for easy use.

[0003] Since the SMC sheet itself has a certain toughness, there will be a large friction between the two when the cutting blade contacts it for cutting. When the cutter moves, it is easy to drive the sheet to move or bend and deform, making it difficult to ensure the flatness of the cut. Therefore, a SMC sheet cutting mechanism is proposed to address the above problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an SMC sheet cutting mechanism, which can press down and fix the SMC sheet near the incision during cutting, so that the sheets on both sides of the cutting mouth cannot move, thereby achieving the fixation of the cutting position, and is not easy to cause the sheet to move due to the movement of the tool, thereby making the incision uneven, thereby solving the technical problem in the prior art that when using a rotating blade to cut the SMC sheet, it is easy to cause the sheet to move, thereby making it difficult to ensure the flatness of the incision.

[0005] In order to solve the above problems, the following technical solutions are provided:

[0006] A SMC sheet cutting mechanism is designed, including a workbench, characterized in that a cutting mechanism and a feeding mechanism are fixedly arranged on the upper surface of the workbench from right to left, respectively, the cutting mechanism includes a cutting gantry, a cutting hydraulic cylinder is fixedly arranged at the center of the lower end surface of the top crossbeam of the cutting gantry, a transmission plate is fixedly connected to the output shaft end of the cutting hydraulic cylinder, a parallel double pressure plate is fixedly arranged on the left side of the lower end surface of the transmission plate, a screw transmission mechanism is fixedly arranged on the right side of the lower end surface of the transmission plate, a cutting motor is installed below the screw transmission mechanism, the output shaft of the cutting motor extends into the parallel double pressure plate and the shaft end is fixedly connected with a cutting blade, and the cutting blade is arranged in the parallel double pressure plate.

[0007] Furthermore, a sliding groove for the output shaft of the cutting motor to slide is provided on the plate body on the right side of the parallel double pressure plate.

[0010] The above structure can drive the screw to rotate through the screw motor, thereby controlling the sliding block threadedly connected to the screw to slide back and forth, thereby driving the cutting motor fixedly connected to the sliding block to move, and completing a complete cutting process.

[0011] Furthermore, an end restraining piece is fixedly provided on the side of the cutting gantry, and an end of the screw rod away from the screw rod motor is rotatably connected to the end restraining piece.

[0012] The above-mentioned structural form can restrain the free end of the screw rod by the end restraining piece, thereby preventing the end of the screw rod from being deformed by force.

[0013] Furthermore, a cutting groove is provided on the upper surface of the workbench at a position directly below the cutting blade, and the lowest point of the cutting blade is located in the cutting groove.

[0014] The above structural form can provide necessary conditions for the cutting work of the cutting blade.

[0015] Furthermore, the feeding mechanism includes a feeding gantry, a feeding hydraulic cylinder is fixedly arranged at the center of the lower end surface of the top crossbeam of the feeding gantry, the output shaft of the feeding hydraulic cylinder is fixedly connected to a roller mounting frame, and an electric roller is installed below the roller mounting frame.

[0016] The above-mentioned structural form can change the working height of the electric roller through the feeding hydraulic cylinder, which is convenient for adjusting the distance between the electric roller and the driven roller, and thus can play a good feeding role for sheets of different thicknesses.

[0017] Furthermore, a mounting groove is provided on the work table at a position directly below the electric roller, and a driven roller is rotatably arranged in the mounting groove.

[0018] The above-mentioned structural form can clamp the sheet material by the combination of the driven roller and the electric roller, thereby preventing the sheet material from sliding relative to each other during the conveying process and affecting the conveying efficiency.

[0019] Furthermore, a scratch-proof groove is provided at the left end edge of the workbench, and support legs are fixedly provided at the four corners of the lower end surface of the workbench.

[0020] In the above structural form, the anti-scratch groove can prevent the sheet from being damaged due to scratches between the sheet and the end of the worktable during feeding.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] The utility model discloses a double parallel pressure plate, which can fall with the cutting blade when cutting, and has a pressing and fixing effect on both ends of the cutting part. Then the cutting blade is driven by the screw transmission mechanism and moves horizontally to the other end to complete the cutting of the sheet between the double parallel pressure plates. This cutting method can effectively prevent the sheet from sliding and deforming during the cutting process, so that the incision has a higher flatness. BRIEF DESCRIPTION OF THE DRAWINGS

In the above structural form, the anti-scratch groove 13 can prevent the sheet from being damaged due to scratches between the sheet and the end of the work table 1 during feeding.

[0039] The use principle and use process of the utility model are as follows: the end of the sheet is laid on the work table 1 so that it is located between the feeding mechanisms 3, the feeding hydraulic cylinder 32 works to change the working height of the electric roller 34, and the distance between the electric roller 34 and the driven roller 35 is adjusted, so that the driven roller 35 and the electric roller 34 work in combination to clamp the sheet, and then the electric roller 34 works and rotates to drive the sheet to move forward, completing the feeding work.

[0040] When cutting, the cutting hydraulic cylinder 22 works to push the transmission plate 23 connected at the bottom to move downward, so that the parallel double pressure plate 24 can fall together with the cutting blade 27 during cutting.
