In order to solve the above technical problems, the embodiment provides a prepreg anti-crease cutting device, as shown in fig. 1, which includes a supply assembly 10 for conveying prepregs, and a receiving platform 20 disposed at one side of the supply assembly 10 and used for loading the prepregs, wherein a cutting assembly 30 is disposed between the supply assembly 10 and the receiving platform 20, the supply assembly 10 conveys the prepregs to the receiving platform 20, the cutting assembly 30 between the supply assembly 10 and the receiving platform 20 is movable upward to cut the prepregs, and then the cut prepregs are placed on the receiving platform 20, a blowing assembly is disposed at one side of the supply assembly 10 close to the cutting assembly 30, and the blowing assembly can blow air toward a lower side of the prepregs, so that the prepregs to be cut are not completely attached to the cut prepregs on the receiving platform 20 during the transferring process, and the prepregs to be cut are easy to be transported forward, prevent the prepreg from forming wrinkles, and improve the production efficiency and the product quality.

Specifically, as shown in fig. 2 and 4, the feeding assembly 10 includes a base 11 and a driving roller 14 installed on the base 11 and used for conveying the prepreg, wherein the driving roller 14 is driven by a motor fixed on a side of the base 11, and further rotates through the driving roller 14 to achieve the purpose of conveying the prepreg. And a discharge port 13 for discharging the prepregs is formed in the side surface of the base 11 close to the cutting assembly 30. The prepreg is continuously conveyed out from the discharge port 13 of the base 11 through the transmission conveying action of the transmission roller 14, and the prepreg is cut and placed on the material receiving table 20 through the cutting assembly 30 between the feeding assembly 10 and the material receiving table 20, so that the purpose of cutting the prepreg is achieved. Wherein, the periphery of the material receiving platform 20 is provided with a baffle 21, and the cut prepreg is prevented from sliding out of the material receiving platform 20 by the baffle 21.

As shown in fig. 3, the cutting assembly 30 includes a cutting knife 31 located below the limiting plate 12 and a driving assembly 32 for driving the cutting knife 31 to move upwards to cut the prepreg, a plurality of supporting blocks 34 are embedded at the bottom of the cutting knife 31, a push plate 33 is fixedly connected to the bottom of the supporting blocks 34, and the driving assembly 32 is fixedly connected to the push plate 33. Drive push pedal 33 through drive assembly 32 and reciprocate, realize that drive cutting knife 31 reciprocates in order to cut the prepreg, drive assembly 32 is for driving actuating cylinder, and the flexible end that drives actuating cylinder is fixed in the middle part of push pedal 33 to realize that cutting knife 31 keeps the horizontality.

In order to realize that the cutting knife 31 can move up and down smoothly to cut the prepreg, support guide posts 35 are connected to both sides of the driving assembly 32 at the bottom of the push plate 33. Through the direction and the supporting role of supporting guide post 35, realize that cutting knife 31 can reciprocate steadily when cutting the prepreg, guarantee that the back prepreg incision of cutting is level and smooth.

When the cutting knife 31 moves upwards for cutting, in order to prevent the supporting block 34 arranged at the bottom of the cutting knife 31 from impacting the bottom of the base platform 11 and the bottom of the material receiving platform 20, buffer cushion blocks are arranged at the bottom of the base platform 11 and the bottom of the material receiving platform 20, so that the cutting knife 31 can be prevented from moving upwards and overshooting while avoiding collision, and the stability of the device is improved.

Because the hardness of the prepreg of the PP material is insufficient and the prepreg is static, when the prepreg to be cut is stacked on the cut prepreg in the transferring process, the prepreg is difficult to transport and transfer in the cutting process due to the mutual adsorption effect of static electricity, and therefore, a blowing assembly is arranged on one side, close to the cutting assembly 30, of the feeding assembly 10 and is arranged on the side face of the base 11 and below the discharge port 13. The air blowing assembly can blow towards the lower part of the prepreg, so that the prepreg to be cut in the transferring process can not be completely attached to the cut prepreg on the material receiving table 20, the prepreg to be cut is easy to transport forwards, the prepreg is prevented from forming wrinkles, and the production efficiency and the product quality are improved.

Specifically, as shown in fig. 2, the blowing assembly includes a plurality of air outlets 12 formed in the side surface of the base 11, air inlets 16 formed in the end surface of the base 11 and communicated with the air outlets 12, and an electromagnetic controller 15 connected to the air inlets 16, the air outlets 12 are located below the air outlets 13, when the prepreg comes out from the air outlets 13 of the base 11, the part of the prepreg which is to be conveyed out is overlapped on the cut prepreg on the material receiving table 20, at this time, air is periodically supplied to the air inlets 16, and then air is blown out from the air outlets 12 to the bottom surface of the conveyed prepreg, wherein the air outlets 12 are uniformly arranged along the extending direction of the air outlets 13 to achieve uniform air blowing, so that the conveyed prepreg slightly floats, and further, the prepreg to be cut cannot be completely attached to the cut prepreg on the material receiving table 20 during the transfer process, the prepreg to be cut is easy to transport forwards, and the prepreg is prevented from forming wrinkles.

Furthermore, the prepreg needs to be cut by a cutting knife 31 after the prepreg extends out of a fixed length, the blowing assembly does not blow air at the moment, the prepreg is attached downwards, and then cutting is completed, therefore, an electromagnetic controller 15 is connected between the air inlet hole 16 and the air pump, the electromagnetic controller 15 can be an electromagnetic valve, air is supplied to or cut off from the air inlet hole 16 under the control of the electromagnetic controller 15, and periodic air blowing of the air outlet hole 12 is realized.

Further, the electromagnetic controller 15 is electrically connected to the driving assembly 32, and when the driving assembly 32 drives the cutting knife 31 to cut the prepreg upwards, the electromagnetic controller 15 controls the air outlet 12 to stop blowing air.
