[0023] Embodiment 1

[0024] See also Figure 1-5 As shown, the utility model is a slitting device for prepreg production, comprising a main frame 1, a traction roller 2 is rotatably connected to the inner side of the main frame 1, and a slitting mechanism 3 for slitting the prepreg is arranged on the main frame 1; the slitting mechanism 3 comprises a positioning column 31 fixedly connected to the inner side of the main frame 1, a slide seat 32 is slidably connected to the positioning column 31, two slide seats 32 are arranged, and the two slide seats 32 are connected by an adjustment mechanism 33, a dovetail groove 34 is opened at the lower side of one side of the slide seat 32, and the bottom of the dovetail groove 34 is open. A holder 35 is clamped in the dovetail groove 34, a groove 36 is provided on the top of the holder 35, a blade assembly 37 is fixedly connected to the holder 35, and a positioning block 39 used in conjunction with the groove 36 is connected to the slide seat 32 through a movable mechanism 38. The holder 35 is clamped in the dovetail groove 34 and the holder 35 is positioned by the cooperation of the positioning block 39 and the groove 36. At the same time, the positioning block 39 and the groove 36 can be separated by the movable mechanism 38, thereby facilitating the disassembly and assembly of the blade assembly 37 and facilitating the subsequent replacement of the blade assembly 37.

[0025] The other side of the slide seat 32 is provided with a movable groove 4 , and the interior of the slide seat 32 is provided with an movable cavity 5 which is connected with the movable groove 4 and the dovetail groove 34 respectively.

[0026] One side of the bottom of the positioning block 39 is provided with an inclined surface, and the top of the inclined surface is flush with the opening of the bottom of the active cavity 5 , and the positioning block 39 is slidably connected with the active cavity 5 .

[0027] The movable mechanism 38 includes a spring 381 and a straight rod 382 respectively fixedly connected to the positioning block 39 , one end of the spring 381 is fixedly connected to the inside of the movable cavity 5 , and one end of the straight rod 382 passes through the movable slot 4 and extends to the outside of the slide seat 32 .

[0028] An upper guide roller 6 and a lower guide roller 7 are rotatably connected to the inner side of the main frame 1 .

[0029] Embodiment 2

[0030] Based on Example 1, see Figure 1 and Figure 2 shown.

[0031] The adjusting mechanism 33 includes a screw rod 331 threadedly connected to the slide seat 32, the screw rod 331 is a bidirectional screw rod, one end of the screw rod 331 is rotatably connected to the inner side of the main frame 1, the other end of the screw rod 331 penetrates the main frame 1 and extends to the outside of the main frame 1, and the other end of the screw rod 331 is fixedly connected to a handle 332. By setting the adjusting mechanism 33, the position of the blade assembly 37 is adjusted by using the adjusting mechanism 33. Compared with the existing adjustment method, the position of the blade assembly 37 can be adjusted more accurately.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] The working principle of the utility model is as follows: the position of the blade assembly 37 is adjusted according to the width of the prepreg to be cut, and the screw rod 331 is driven to rotate by rotating the handle 332, thereby driving the slide 32 to slide on the positioning column 31, so as to adjust the blade assembly 37 to a suitable position. After that, the prepreg is placed on top of the traction roller 2, and then the prepreg is wound from under the positioning column 31 to above the upper guide roller 6, and the prepreg can be cut by the blade assembly 37, and the cut product is guided and conveyed by the upper guide roller 6, and the remaining material after cutting is guided and conveyed by the lower guide roller 7. When the blade assembly 37 needs to be replaced, the straight rod 382 is lifted up to move the positioning block 39 out of the groove 36, so that the holder 35 can be removed from the dovetail groove 34 to replace the blade assembly 37. During installation, the holder 35 is placed in the dovetail groove 34 and pushed forward. The holder 35 squeezes the positioning block 39, causing the positioning block 39 to move into the movable cavity 5 and compress the spring 381. When the positioning block 39 and the groove 36 are in the same vertical line, the spring 381 will drive the positioning block 39 to be stuck in the groove 36, so that the holder 35 will not detach from the slide seat 32. In summary, the device is convenient for disassembly and assembly of the blade assembly 37, and is convenient for subsequent replacement of the blade assembly 37. Compared with the existing adjustment method, the position adjustment of the blade assembly 37 is more precise.
