[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 3 As shown, a stainless steel pipe cutting device provided by an embodiment of the utility model includes a frame 1 and a cutting knife 2. Two adjusting circular grooves 3 are symmetrically provided on the frame 1. A cutting circular roller 4 is installed in the two adjusting circular grooves 3 for co-rotation. A plurality of cutting knives 2 are evenly installed on the cutting circular roller 4. The cutting circular roller 4 can slide in the adjusting circular groove 3 to adjust the cutting position of the cutting knife 2.

[0025] Specifically, the frame 1 is a frame body on which devices such as conveying, cutting, and welding of stainless steel strips are installed. The cutting knife 2 is an annular blade. When the cutting knife 2 rotates, the stainless steel strip passes through the position of the cutting knife 2, so that the cutting knife 2 can cut the stainless steel strip and cut the overall rolled stainless steel strip into multiple strips of stainless steel strips with the same width direction. However, the stainless steel strip needs to be transported smoothly to evenly cut the stainless steel strip. When the output of the stainless steel strip deviates, it will cause the cutting of the stainless steel strip to deviate, which will lead to uneven cutting of the stainless steel strip, and the width of the stainless steel strip is different, which affects the subsequent winding and welding of the stainless steel strip. When the stainless steel strip deviates, the rolled stainless steel strip is difficult to adjust, and the position of the cutting knife 2 needs to be adjusted to adapt to the deviation of the stainless steel strip. At this time, it is necessary to adjust the position of the cutting roller 4 in the adjusting circular groove 3 so that the cutting roller 4 drives the cutting knife 2 to move until the cutting knife 2 moves to a suitable cutting position. The position of the cutting knife 2 enables the cutting knife 2 to continue cutting the stainless steel strip, and can cut the stainless steel strip into multiple strips with the same width. In the prior art, when the common stainless steel strip passes through the position of the cutting knife 2, the cutting knife 2 cuts the stainless steel strip. When the stainless steel strip is being cut and conveyed, the stainless steel strip may be offset during conveying or the stainless steel strip roll may be lateralized. Since the position of the cutting knife 2 is fixed and it is troublesome to adjust the stainless steel strip roll, the cutting of the stainless steel strip by the cutting knife 2 is uneven, thereby affecting the cutting effect of the stainless steel strip. In the present embodiment, when the stainless steel strip passes through the position of the cutting knife 2, the cutting knife 2 cuts the stainless steel strip. When the stainless steel strip is lateralized during conveying, the position of the cutting roller 4 in the adjusting circular groove 3 is adjusted, so that the cutting roller 4 drives the position of the cutting knife 2 to change, until the cutting knife 2 moves to the best cutting position, so that the cutting knife 2 can cut the stainless steel strip with equal width.

[0026] Furthermore, two straight grooves 5 are symmetrically provided on the frame 1, a straight plate 6 is slidably installed in each of the two straight grooves 5, and the two adjusting circular grooves 3 are respectively provided on the two straight plates 6; a first threaded rod 7 is rotatably installed on one of the straight plates 6, a threaded groove 8 is provided at one end of the cutting circular roller 4, and the threaded groove 8 and the first threaded rod 7 are threadedly connected; a first driving member 9 is provided and connected to the first threaded rod 7; a second driving member 10 is installed on the outer wall of the other straight plate 6, a square active rod 11 is installed at the output end of the second driving member 10, a square groove 12 is provided at the other end of the cutting circular roller 4, and the square active rod 11 is slidably installed in the square groove 12.

[0027] Specifically, when it is necessary to adjust the position of the cutting circular roller 4 in the adjusting circular groove 3, the first driving member 9 is started (the first driving member 9 is a device whose driving end can perform forward and reverse motion, which can be a motor or a manually driven crank structure) to drive the first threaded rod 7 to rotate. Since the first threaded rod 7 is rotatably installed on the straight plate 6, the first threaded rod 7 will only rotate on the straight plate 6 without axial movement, and since the output end of the second driving member 10 (the second driving member 10 is a device whose driving end can perform forward and reverse motion, preferably a motor) is provided with a square active rod 11, and a sliding installation device is provided between the square active rod 11 and the square groove 12 on the cutting circular roller 4. The first threaded rod 7 is arranged so that the first threaded rod 7 and the threaded groove 8 on the cutting roller 4 are meshed with each other, thereby driving the cutting roller 4 to slide in the adjusting groove 3, so that the cutting roller 4 drives the cutting knife 2 to move to a suitable cutting position, so that the cutting knife 2 can stably cut the stainless steel strip. When it is necessary to drive the cutting roller 4 and the cutting knife 2 to rotate, the second driving member 10 is started to drive the square active rod 11 to rotate. Since the square active rod 11 is slidably connected with the square groove 12 on the cutting roller 4, the square active rod 11 drives the cutting roller 4 to rotate through the square groove 12, and the cutting roller 4 drives the cutting knife 2 to rotate, so that the cutting knife 2 can smoothly cut the stainless steel strip.

[0028] Furthermore, a third driving member 13 is installed at the bottom end of the frame 1, and a supporting plate 14 is installed at the output end of the third driving member 13. The supporting plate 14 is located at the bottom end of the cutting knife 2. A plurality of cutting grooves 15 are evenly opened on the supporting plate 14. The cutting grooves 15 cooperate with the cutting knife 2. Specifically, before the cutting knife 2 cuts the stainless steel strip, the third driving member 13 is started (the third driving member 13 is a device capable of linear reciprocating motion at the driving end, which can be a mechanism capable of linear reciprocating motion such as a cylinder, an electric push rod, and a hydraulic cylinder) to drive the supporting plate 14 to press against the position of the cutting knife 2. , so that the cutting groove 15 on the supporting plate 14 and the cutting knife 2 are similar to a socket fit (that is, the cutting knife 2 can enter the cutting groove 15, and the cutting knife 2 will not contact the supporting plate 14). When the cutting knife 2 cuts the stainless steel strip, the cutting knife 2 rotates in the cutting groove 15, so that the cutting knife 2 can smoothly cut the stainless steel strip, thereby improving the stability of the stainless steel strip cutting. When the position of the cutting knife 2 changes, the third driving member 13 can also be slidably installed on the frame 1, so that the third driving member 13 and the cutting groove 15 on the supporting plate 14 can always cooperate with the cutting knife 2.

[0029] Preferably, two conveying rollers 16 are symmetrically installed on the frame 1 on both sides of the supporting plate 14 in a rotating manner. Specifically, before the stainless steel strip enters the supporting plate 14 and after the cutting knife 2 cuts the stainless steel strip, the two rotating conveying rollers 16 can smoothly convey the stainless steel strip, which provides convenience for the cutting of the stainless steel strip.

[0030] Furthermore, a screw 17 is threadedly installed on each side of the two straight plates 6, the bottom end of the screw is rotatably installed at the bottom end of the straight groove 5, and the top end of the screw 17 is rotatably installed at the top end of the straight groove 5; the top ends of the two screws 17 pass through the frame 1 and are each installed with a first bevel gear 18; two flat plates 19 are symmetrically installed on the top of the frame 1, and a transmission shaft 20 is rotatably installed on the two flat plates 19, and a second bevel gear 21 is installed at each end of the transmission shaft 20, and the second bevel gear 21 and the corresponding first bevel gear 18 are meshed with each other, and a fourth driving member 22 is installed on the side wall of one side of the frame 1, and the output end of the fourth driving member 22 is connected to the transmission shaft 20.

[0031] Specifically, when it is necessary to adjust the distance between the cutting knife 2 and the supporting plate 14, start the fourth driving member 22 (the fourth driving member 22 is a device that can perform forward and reverse motion at the driving end, preferably a motor) to drive the transmission shaft 20 to rotate, and the transmission shaft 20 simultaneously drives the two second bevel gears 21 to rotate, and the two second bevel gears 21 respectively drive the first bevel gears 18 meshing therewith to rotate in the same direction, and the two first bevel gears 18 drive the lead screws 17 connected thereto to rotate in the same direction, so that the two lead screws 17 simultaneously drive the straight plates 6 threadedly connected thereto to slide in the same direction in the straight groove 5, so that the two straight plates 6 simultaneously drive the cutting roller 4 and the cutting knife 2 to move until the distance between the cutting knife 2 and the supporting plate 14 reaches the optimal cutting position. At this time, the fourth driving member 22 is closed, so that the distance between the cutting knife 2 and the supporting plate 14 reaches the optimal cutting position, thereby providing the cutting effect of the cutting knife 2 on the stainless steel strip.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
