Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices for processing sealing rings, in particular to a cutting device for processing sealing rings. Background Art

[0002] The cutting device is a device that divides a whole object into pieces. When the sealing ring is cut, the cutting device is often used for cutting. The sealing ring is placed on the surface of the drum and is cut by a cutter to rotate and cut the entire rubber ring into multiple sealing rings.

[0003] The inventor discovered during daily use of the cutting device that, since the diameters of the sealing rings mounted on the surface of the drum are of different sizes and the diameter of the drum is fixed, the sealing rings cannot be firmly mounted on the surface of the drum, which causes the sealing rings to shift during cutting, resulting in uneven cutting of the sealing rings and breakage of the cut sealing rings, which in turn causes an impact. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a cutting device for processing a sealing ring.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cutting device for processing a sealing ring, comprising an operating table, a rectangular plate is fixedly connected to the upper top of the operating table, a first motor is fixedly connected to the side of the rectangular plate, a roller is fixedly connected to the output end of the first motor, a propping device is arranged inside the roller, a rectangular groove is opened on the upper top of the operating table, a threaded rod is rotatably connected to the inside of the rectangular groove, a second motor is fixedly connected to the side of the operating table, a threaded rod is fixedly connected to the output end of the second motor, a rectangular groove is threadedly connected to the surface of the threaded rod Rod, the upper top of the rectangular rod is fixedly connected to a U-shaped rod, the side of the U-shaped rod is fixedly connected to a third motor, the output end of the third motor is fixedly connected to a rotating shaft, a cutter is provided on the surface of the rotating shaft, a fixed rod is inserted on the side of the cutter, an adjusting device is provided on the side of the U-shaped rod, the opening device includes a circular groove opened inside the drum, a sliding rod is slidably connected inside the circular groove, one end of the sliding rod is fixedly connected to a trapezoidal block, the inside of the circular groove is slidably connected to a sliding rod, the surface of the sliding rod is fixedly connected to a conical block, and one end of the sliding rod is fixedly connected to an arc plate.

[0006] The effect achieved by the above components is: under the action of the conical block and the trapezoidal block, the arc plate can be stretched outward, thereby increasing the diameter of the drum, thereby making the sealing rings of different diameters firmly fixed on the surface of the drum, and when the sealing ring needs to be cut, the sealing ring is sleeved on the surface of the drum, the first motor is started, thereby making the drum rotate, the second motor is started, the threaded rod is rotated, and the rectangular rod is driven to move, thereby moving the cutter to the surface of the drum, and when it moves to a suitable position, the second motor is stopped, and the third motor is started, thereby making the cutter rotate and cut the sealing ring, thereby cutting the sealing ring.

[0007] Preferably, a round bar is fixedly connected to the side surface of the conical block, and the round bar is a rubber strip.

[0008] The effect achieved by the above components is that, under the action of the round bar, no rigid contact phenomenon occurs when the conical block is pressed toward the trapezoidal block.

[0009] Preferably, a drawstring is fixedly connected to the side surface of the trapezoidal block, and the other end of the drawstring is fixedly connected to one end of the conical block.

[0010] The effect achieved by the above components is: under the action of the pull rope, when there is no need to increase the diameter of the drum, the sliding rod is pulled outward, so that the pull rope pulls the trapezoidal block to move inside the circular groove, thereby making the arc plate stick to the surface of the drum.

[0011] Preferably, one end of the drum is fixedly connected with a rectangular block, a clamping rod is inserted into the side of the rectangular block, and the clamping rod is inserted into the interior of the sliding rod.

[0012] The effect achieved by the above components is: under the action of the clamping rod, the arc plate can be moved to the appropriate position and then fixed. When the sealing ring needs to be fixed on the surface of the drum, if the diameter of the sealing ring is larger than the diameter of the drum, the sliding rod is pressed toward the inside of the drum, so that the conical block squeezes the trapezoidal block to move toward the inner wall of the circular groove. Under the action of the round bar, there is no rigid contact when the conical block is pressed toward the trapezoidal block position, so that the arc plate is moved away from the surface of the drum, thereby increasing the diameter of the drum, and then the sealing ring is firmly fixed to the surface of the drum. If the diameter of the drum does not need to be increased, under the action of the pull rope, when the diameter of the drum does not need to be increased, the sliding rod is pulled outward, so that the pull rope pulls the trapezoidal block to move toward the inside of the circular groove, so that the arc plate is attached to the surface of the drum, thereby achieving the effect of opening.

[0016] The effect achieved by the above components is that under the action of the ball, the friction between the cutter and the adjusting block is reduced, thereby avoiding the phenomenon of the cutter being worn due to excessive friction.

[0017] Preferably, a spring is sleeved on the surface of the round rod, and the two ends of the spring are fixedly connected to the side of the U-shaped rod and one end of the round rod away from the U-shaped rod respectively. A locking rod is inserted into the upper top of the U-shaped rod, and the locking rod is inserted into the interior of the round rod.

[0018] The effects achieved by the above components are: under the action of the spring, the round rod can push the adjustment block to be inserted between the cutters, and under the action of the positioning rod, the adjustment block can be fixed after being adjusted to a suitable position.

[0019] Preferably, a ring groove is provided on the side of the cutter, a protrusion is slidably connected inside the ring groove, one end of the protrusion is fixedly connected to a rope, and the other end of the rope is connected to one side of the adjustment block.

[0020] The effect achieved by the above-mentioned components is: under the action of the rope, after the adjusting block is separated from the cutter, the cutter can be pulled by the rope, so that the distance between the cutters becomes smaller. When the position of the cutter needs to be adjusted, the positioning rod is pulled outward, and then under the action of the spring, the rectangular long plate pushes the adjusting block to be inserted between the cutters. When adjusted to a suitable position, the positioning rod is pressed down, so that the round rod is fixed under the action of the ball, so that the friction between the cutter and the adjusting block is reduced, thereby avoiding the phenomenon that the cutter is worn due to excessive friction. Under the action of the rope, after the adjusting block is separated from the cutter, the cutter can be pulled by the rope, so that the distance between the cutters becomes smaller, thereby achieving the effect of adjustment.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by arranging an expansion device, when it is necessary to fix the sealing ring on the surface of the drum, if the diameter of the sealing ring is larger than the diameter of the drum, the sliding rod is pressed toward the inside of the drum, thereby causing the conical block to squeeze the trapezoidal block and move toward the inner wall of the circular groove. Under the action of the round bar, the conical block is pressed toward the trapezoidal block position without rigid contact, thereby causing the arc plate to move away from the surface of the drum, thereby increasing the diameter of the drum, thereby firmly fixing the sealing ring on the surface of the drum. If it is not necessary to increase the diameter of the drum, under the action of the pull rope, when it is not necessary to increase the diameter of the drum, the sliding rod is pulled outwards, so that the pull rope pulls the trapezoidal block to move toward the inside of the circular groove, thereby causing the arc plate to stick to the surface of the drum, thereby achieving the expansion effect, thereby solving the problem that sealing rings of different diameters cannot be firmly sleeved on the drum surface.

When it is necessary to fix the sealing ring on the surface of the roller 5, if the diameter of the sealing ring is larger than the diameter of the roller 5, the sliding rod 21 is pressed into the inside of the roller 5, so that the conical block 22 presses the trapezoidal block 23 to move toward the inner wall of the circular groove. Under the action of the round bar 26, there is no rigid contact when the conical block 22 is pressed toward the position of the trapezoidal block 23, so that the arc plate 25 is away from the surface of the roller 5, so that the diameter of the roller 5 is increased, and the sealing ring is firmly fixed. The sliding rod 21 is pulled outward under the action of the pull rope 27 so that the diameter of the roller 5 does not need to be increased, so that the pull rope 27 pulls the trapezoidal block 23 to move inside the circular groove, thereby making the arc plate 25 stick to the surface of the roller 5, thereby achieving the effect of stretching. When the position of the cutter 6 needs to be adjusted, the positioning rod 35 is pulled outward, and then under the action of the spring 36, the rectangular long plate 32 pushes the adjusting block 33 to be inserted between the cutters 6.
