DETAILED DESCRIPTION

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a cutting device for straw processing, comprising a bottom plate 1, an electric telescopic rod 2 is fixed on the top of the bottom plate 1, a top plate 3 is fixed on the top of the electric telescopic rod 2, a fixed plate 4 is fixed on the bottom of the top plate 3, a side wall of the fixed plate 4 is provided with a slide groove 5, a slider 6 is slidably installed on the inner wall of the slide groove 5, a connecting block 7 is fixed on the side of the slider 6 away from the slide groove 5, a cutting blade 8 is fixed on the bottom of the connecting block 7, four groups of connecting blocks 7 and cutting blades 8 are provided, and the four groups of connecting blocks 7 and cutting blades 8 are arranged on the fixed plate 4 in a linear array, by starting the electric telescopic rod 2, the top plate 3 can be moved downward, the cutting blade 8 can be moved downward, and then the straw on the bottom plate 1 can be cut, an adjusting mechanism 9 for adjusting the spacing between the cutting blades 8 is provided on the fixed plate 4, and a pressing mechanism 10 is provided on the top plate 3.

[0023] Specifically, the adjustment mechanism 9 includes a groove 91, a threaded rod 92, a knob 95, a threaded sleeve 93, a movable plate 94, an inclined groove 96 and a fixed rod 97; the groove 91 starts at the side wall of the fixed plate 4, the inner wall of the groove 91 is rotatably mounted with a threaded rod 92, the bottom of the threaded rod 92 is fixed with a knob 95, the outer wall of the threaded rod 92 is threadedly connected with a threaded sleeve 93, and the threaded sleeve 93 is slidably mounted on the inner wall of the groove 91. When the knob 95 is rotated forwards and backwards, the threaded sleeve 93 can be moved up and down on the threaded rod 92. The threaded sleeve 93 is movable, a movable plate 94 is fixed to the side wall of the threaded sleeve 93, a fixed rod 97 is fixed to the front of the connecting block 7, an inclined groove 96 is provided on the movable plate 94, and the fixed rod 97 passes through the inclined groove 96. When the threaded sleeve 93 moves up and down, the movable plate 94 is driven to move up and down, so that the inner wall of the inclined groove 96 squeezes the fixed rod 97, and then the slider 6 can be driven to move in the slide groove 5, and the distance between the four groups of cutting blades 8 can be adjusted at the same time, so that the straw can be cut according to the required length of the straw.

[0024] Specifically, the pressing mechanism 10 includes a transmission rod 101, a squeezing spring 103, a stopper 102 and a pressing block 104. The top plate 3 is penetrated by the transmission rod 101, and the transmission rod 101 is slidably connected to the penetration of the top plate 3. The top of the transmission rod 101 is fixed with a stopper 102, the bottom of the stopper 102 is fixed with a squeezing spring 103, the bottom of the squeezing spring 103 is fixed to the top of the top plate 3, and the bottom of the transmission rod 101 is fixed with a pressing block 104. By setting the pressing block 104, the straw can be pressed and fixed. The pressing block 104 is provided in two groups, and the two groups of pressing blocks 104 are symmetrical with the center line of the movable plate 94 in the vertical direction as the axis of symmetry. The arrangement is symmetrical, so that when the straw is cut, the electric telescopic rod 2 moves downward, so that the top plate 3 drives the pressing block 104 to move downward, so that the pressing block 104 presses the straw, and when the straw is pressed, the top plate 3 continues to move downward, so that the pressing block 104 squeezes the transmission rod 101, and the stopper 102 drives the squeezing spring 103 to stretch. Through the squeezing spring 103, the pressing block 104 can always press the straw, and when the top plate 3 continues to move downward, the cutting blade 8 cuts the straw. Because the pressing block 104 fixes the straw, the straw can be prevented from displacement during cutting, which affects the cutting effect of the straw.

[0025] Working principle: When it is necessary to cut the straw, the straw can be placed on the top of the bottom plate 1 to prevent it from being at the bottom of the pressing block 104. When the knob 95 is rotated forwards and backwards, the threaded sleeve 93 can move up and down on the threaded rod 92, driving the movable plate 94 to move up and down, so that the inner wall of the inclined groove 96 squeezes the fixed rod 97, and then drives the slider 6 to move in the slide groove 5. The four sets of cutting blades 8 can be adjusted to facilitate cutting the straw according to the required length of straw.

[0026] When the distance of the cutting blades 8 is adjusted, the electric telescopic rod 2 can be started to drive the top plate 3 to move downward, and when the top plate 3 moves downward, the pressing block 104 is driven to move downward, so that the pressing block 104 presses the straw, and when the straw is pressed, the top plate 3 continues to move downward, so that when the cutting blade 8 cuts the straw, the pressing block 104 fixes the straw, which can prevent the straw from shifting during cutting and affecting the cutting effect of the straw.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
