A fixing plate is fixedly mounted on the top of the first slider. However, this cutting machine does not cut the two sides of the fiber felt during use, resulting in uneven edges and low practicality. Utility Model Content

[0004] This utility model provides an alumina fiber felt cutting device, which solves the problem proposed in the prior art that the cutting machine does not cut both sides of the fiber felt when cutting the fiber felt, resulting in uneven edges of the fiber felt and low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cutting device for alumina fiber felt includes a base. A guiding mechanism is provided on the top of the base. The guiding mechanism includes two mounting seats bolted to the outer wall of the top of the base, a guide shaft with both ends penetrating and connected to the outer walls of the two mounting seats via bearings, and a guide roller fixed to the outer wall of the guide shaft. An adjusting assembly is provided between the two mounting seats. The adjusting assembly includes mounting plates bolted to the outer walls of the two mounting seats on both sides, an adjusting cylinder bolted to one outer wall of the mounting plates, a mounting frame bolted to one end of the piston rod of the adjusting cylinder, an adjusting shaft with both ends penetrating and connected to the outer walls of the mounting frame via bearings, and an adjusting roller fixed to the outer wall of the adjusting shaft. A conveying assembly is provided between the two mounting seats. The conveying assembly includes a conveying motor bolted to one outer wall of the mounting seat, a conveying shaft connected to one end of the output shaft of the conveying motor via a coupling, two support rollers slidably sleeved on the outer walls of both ends of the conveying shaft, an adjusting motor bolted to one outer wall of the mounting seat, and a guide roller... A coupling connects a double-ended screw to one end of the output shaft of the regulating motor and two sliders respectively screwed to both ends of the double-ended screw. An extrusion assembly is provided above the base. The extrusion assembly includes a first fixed plate bolted to the top outer wall of the two mounting seats, a first lifting cylinder bolted to the top outer wall of the first fixed plate, a lifting frame bolted to the bottom end of the piston rod of the first lifting cylinder, mounting shafts penetrating at both ends and connected to the outer walls of both sides of the lifting frame via bearings, two extrusion rollers slidably sleeved on the outer walls of both ends of the mounting shafts, and two ring-cutting blades bolted to the outer walls of one side of the two extrusion rollers. A cutting assembly is provided on one side of the lifting frame. The cutting assembly includes a second fixed plate bolted to the top outer wall of the two mounting seats, a second lifting cylinder bolted to the top outer wall of the second fixed plate, a lifting plate bolted to the bottom end of the piston rod of the second lifting cylinder, a cutting blade bolted to the bottom outer wall of the lifting plate, and support plates bolted to the outer walls of one side of the two mounting seats.

[0007] Preferably, each of the two mounting bases has two stabilizing plates bolted to one outer wall, and the four stabilizing plates are bolted to the top outer wall of the base.

[0008] Preferably, the two sides of the mounting frame abut against the outer wall of one side of the two mounting seats, and each of the outer walls of one side of the two mounting seats has a slide rail along the length direction, and the two ends of the adjusting shaft are slidably installed in the two slide rails respectively.

[0009] The above scheme guides the fiber felt by adjusting rollers and guide rollers. The piston rod of the adjusting cylinder moves, which drives the mounting frame and adjusting rollers to move. The adjusting rollers tension the fiber felt, making the surface of the fiber felt taut and preventing wrinkles from forming during transportation.

[0010] Preferably, one end of the conveying shaft passes through and is connected to the outer wall of the mounting base via a bearing, and a limiting groove is opened on the outer wall of the conveying shaft. Pins are inserted into the outer walls of the two support rollers, and the two pins are slidably installed in the limiting grooves. One end of the bidirectional screw passes through and is connected to the outer wall of the mounting base via a bearing. The two sliders are slidably sleeved on the outer wall of the conveying shaft, and the two sliders are connected to the outer wall of one end of the two support rollers via bearings.

[0011] Preferably, two first limiting rods are fixed on the top outer wall of the lifting frame, and the two first limiting rods are respectively inserted through and slidably installed on the top outer wall of the first fixed plate. Fastening nuts are screwed onto the outer walls of the two extrusion rollers, and the two fastening nuts are respectively screwed onto the outer wall of the mounting shaft.

[0012] The above scheme involves adjusting the motor output shaft to drive a bidirectional screw to rotate. The bidirectional screw then moves two sliders and two support rollers, ensuring the distance between the two support rollers matches the factory width of the fiber felt. Subsequently, the piston rod of the first lifting cylinder lowers the lifting frame and two extrusion rollers, moving the two extrusion rollers so that the two ring cutters contact the outer walls of the two support rollers. Then, the piston rod of the first lifting cylinder rises, placing one end of the fiber felt above the two support rollers. The piston rod of the first lifting cylinder then descends, causing the extrusion rollers to contact the support rollers and extrude pressure on the fiber felt. The output shaft of the conveyor motor drives the conveyor shaft and the two support rollers to rotate, thereby conveying the fiber felt. Under the action of friction, the extrusion rollers rotate, while the ring cutters cut both sides of the fiber felt.

[0013] Preferably, two second limiting rods are fixed on the top outer wall of the lifting plate, and the two second limiting rods are respectively inserted through and slidably installed on the top outer wall of the second fixed plate, and a cutting hole is opened on the top outer wall of the support plate.

[0014] The above scheme uses the piston rod of the second lifting cylinder to descend, which drives the cutting blade to descend. The cutting blade and the cutting hole on the support plate work together to cut the fiber felt.

[0015] The beneficial effects of this utility model are as follows:

[0016] The output shaft of the adjusting motor drives the bidirectional screw to rotate, which in turn moves two sliders and two support rollers, ensuring the distance between the two support rollers matches the factory width of the fiber felt. Then, the piston rod of the first lifting cylinder drives the lifting frame and two extrusion rollers to descend, moving the two extrusion rollers so that the two ring cutters contact the outer walls of the two support rollers. Next, the piston rod of the first lifting cylinder rises, placing one end of the fiber felt above the two support rollers. The piston rod of the first lifting cylinder then descends, causing the extrusion rollers to contact the support rollers and compress the fiber felt. The output shaft of the conveying motor drives the conveying shaft and the two support rollers to rotate, thus conveying the fiber felt. Under the action of friction, the extrusion rollers rotate, while the ring cutters cut the two sides of the fiber felt. This allows for simultaneous conveying and cutting of the fiber felt's sides, resulting in flat edges and improved practicality. Attached Figure Description
