Description

Technical Field

[0001] The utility model relates to the technical field of stripping cloth cutting, in particular to a small-width stripping cloth thermal cutting device. Background Art

[0002] Conventional large cutting machines can process stripping cloth with a width of 2.3m. The semi-finished stripping cloth processed is a large roll of full-width semi-finished stripping cloth after weaving, washing and shaping. This semi-finished product is generally 6000m long, about 200cm wide, and has a roll diameter of about 1m. Conventional cutting machines are mainly used for batch production of large-volume stripping cloth. The finished product of stripping cloth is generally 10cm wide and 300m long. The minimum production width is 5cm. In order to avoid defective products when cutting with conventional large cutting machines, secondary cutting is required. Therefore, a special small cutting machine that can be used to slitting single rolls of stripping cloth and small-width stripping cloth has been developed.

[0003] However, when the prior art is used, if the release cloth cannot be stably cut, the cutting quality is affected, and if the cutter cannot be replaced, the cutting efficiency is affected. Utility Model Content

[0004] The purpose of the utility model is to provide a small-width stripping cloth thermal cutting device to solve the problems raised by the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] Preferably, the output end of the winding tension controller is fixedly connected to a winding shaft, and the unwinding shaft and the winding shaft are both rotatably connected between the two boxes.

[0008] Preferably, one end of the first screw is fixedly connected to a first knob, and the limiting hole is adapted to the size of the first screw.

[0009] Preferably, one end of the second screw is fixedly connected to the second knob, and the other end of the second screw is threadedly connected to an arc-shaped limiting plate, and the arc-shaped limiting plate is in contact with the surface of the mounting rod.

[0010] Preferably, the output end of the first motor is fixedly connected to one end of the bidirectional screw rod, and a cutter is fixedly connected to the bottom of the mounting rod.

[0011] Preferably, two cloth guide shafts are rotatably connected between the two boxes, and a control area is provided on the surface of one side of the box, and the control area is electrically connected to the first motor, the second motor, and the electric push rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When the utility model is in use, the control area starts the tension controller to adjust the input and output currents of the magnetic powder brake, controls the coil current size, and makes the output torque reach the required torque. Based on the electromagnetic principle, the magnetic powder is used to transmit the torque, and the excitation current and the transmission torque are in a linear relationship. By adjusting the size of the excitation current, the size of the torque can be effectively controlled. Finally, the second motor connected to the winding magnetic powder brake is started to drive the winding magnetic powder brake to rotate. The rotation of the winding magnetic powder brake drives the chain to rotate, and the chain drives the tension controller to rotate, thereby realizing effective control of the running speed and ensuring that the stripping cloth can be cut at a stable running speed, so as to solve the problem of affecting the cutting quality if the stripping cloth cannot be cut stably.

[0014] At the same time, when the present invention is in use, as time goes by, the cutter will become blunt due to longer use and rust, which affects the cutting efficiency. Therefore, by turning the first knob and the second knob, the first knob and the second knob will drive the first screw and the second screw to move toward the outside of the first hollow connecting piece and the second hollow connecting piece respectively, thereby driving the arc limit plate away from the mounting rod until the first screw is away enough to remove the mounting rod from the first hollow connecting piece, and finally remove the mounting rod from the first hollow connecting piece and the second hollow connecting piece, and then install the new cutter into the first hollow connecting piece and the second hollow connecting piece according to the reverse operation of the above method, so as to solve the problem of affecting the cutting efficiency if the cutter is not replaced.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5The utility model provides a technical solution: a small-width demoulding cloth thermal cutting device, comprising two box bodies 1, two second motors 22 are fixedly connected inside the box body 1 on one side, the output end of the second motor 22 on one side is fixedly connected to the unwinding magnetic powder brake 23, the output end of the unwinding magnetic powder brake 23 is fixedly connected to the unwinding shaft 4, the output end of the second motor 22 on one side is fixedly connected to the winding magnetic powder brake 24, the output end surface of the winding magnetic powder brake 24 is fixedly connected to the ring chain 26, one end of the ring chain 26 is fixedly connected to the winding tension controller 25, the output end of the unwinding magnetic powder brake 23 is fixedly connected to the unwinding shaft 4, the output end of the winding tension controller 25 is fixedly connected to the winding shaft 3, the unwinding shaft 4 and the winding shaft 3 are both rotatably connected Between the two boxes 1, an electric push rod 6 is fixedly connected to the top of the box 1, a fixed plate 7 is fixedly connected to the top of the electric push rod 6, two support plates 8 are fixedly connected to the bottom of the fixed plate 7, a bidirectional screw rod 9 is threadedly connected between the two support plates 8, a first motor 10 is fixedly connected to the surface of the support plate 8 on one side, two wire seats 11 are threadedly connected to the surface of the bidirectional screw rod 9, a first hollow connector 13 and a second hollow connector 14 are fixedly connected to the surface of the wire seat 11, a first screw 15 is threadedly connected to the surface of the first hollow connector 13, a mounting rod 19 is threadedly connected to the surface of the first screw 15, and two limiting holes 20 are provided on the surface of the mounting rod 19. The second hollow connector 14 is threadedly connected to the second screw 17 on both sides, and the first screw 15 is threadedly connected to the second screw 17 on both sides. One end is fixedly connected with a first knob 16, a limiting hole 20 is adapted to the size of the first screw 15, one end of the second screw 17 is fixedly connected with a second knob 18, and the other end of the second screw 17 is threadedly connected with an arc-shaped limiting plate 21, and the arc-shaped limiting plate 21 is in contact with the surface of the mounting rod 19. The stripping cloth is placed on the surface of the unwinding shaft 4, and then one end is fixedly connected to the winding shaft 3. The input and output currents of the magnetic powder brake are adjusted by the tension controller to control the coil current so that the output torque reaches the required torque. Based on the electromagnetic principle, the torque is transmitted by magnetic powder, and the excitation current and the transmission torque are in a linear relationship. By adjusting the excitation current, the torque can be effectively controlled. Finally, the second motor 22 connected to the winding magnetic powder brake 24 is started to bring the stripping cloth to the winding shaft 3. The dynamic winding magnetic powder brake 24 rotates, and the rotation of the winding magnetic powder brake 24 will drive the chain to rotate, and the chain will drive the tension controller to rotate, thereby realizing effective control of the running speed, ensuring that the stripping cloth can be cut at a stable running speed. During cutting, as the stripping cloth is cut thinner and thinner, it is inconvenient for the cutter 12 to contact the stripping cloth. Therefore, after cutting a certain thickness, the electric push rod 6 is started, and the electric push rod 6 will drive the fixed plate 7 to move downward, and the fixed plate 7 moves downward to drive the two support plates 8 to move downward, and the support plate 8 moves downward to drive the bidirectional screw rod 9 to move downward, and the bidirectional screw rod 9 moves downward to drive the wire holder 11 to move downward, and the wire holder 11 moves downward to drive the first hollow connector 13 and the second hollow connector 14 to move downward.The first hollow connecting member 13 and the second hollow connecting member 14 move downward, driving the two cutters 12 to move downward until they move to a suitable position, thereby facilitating cutting. As time goes by, the cutter 12 will become blunt due to long-term use and rust, affecting cutting efficiency. Therefore, by turning the first knob 16 and the second knob 18, the first knob 16 and the second knob 18 will drive the first screw rod 15 and the second screw rod 17 to move outward of the first hollow connecting member 13 and the second hollow connecting member 14 respectively, thereby driving the arc-shaped limit plate 21 away from the mounting rod 19 until the first screw rod 15 is away enough to remove the mounting rod 19 from the first hollow connecting member 13, and finally remove the mounting rod 19 from the first hollow connecting member 13 and the second hollow connecting member 14, and then install the new cutter 12 into the first hollow connecting member 13 and the second hollow connecting member 14 according to the reverse operation of the above method.

[0023] like Figure 1 and Figure 2 As shown, the output end of the first motor 10 is fixedly connected to one end of the bidirectional screw rod 9, and the cutter 12 is fixedly connected to the bottom of the mounting rod 19. The first motor 10 drives the bidirectional screw rod 9 to rotate. The rotation of the bidirectional screw rod 9 will drive the wire seat 11 to move in the corresponding direction or in the opposite direction on its surface, thereby driving the two cutters 12 to move closer and farther away.

[0024] like Figure 1 As shown, two cloth guide shafts 5 are rotatably connected between the two boxes 1, and a control area 2 is provided on the surface of the other side of the box 1. The control area 2 is electrically connected to the first motor 10, the second motor 22, and the electric push rod 6. The cloth guide shaft 5 is used to guide the demolding cloth, and the control area 2 is used to control the start of the first motor 10, the second motor 22, and the electric push rod 6.

[0025] Working principle: When in use, place the stripping cloth on the surface of the unwinding shaft 4, and then fix one end to the rewinding shaft 3;

[0026] Then, the tension controller is activated through control area 2 to adjust the input and output currents of the magnetic powder brake, controlling the coil current to achieve the required output torque. Based on the electromagnetic principle, the magnetic powder is used to transmit torque, and the excitation current and the transmitted torque are linearly related. By adjusting the excitation current, the torque can be effectively controlled. Finally, the second motor 22 connected to the winding magnetic powder brake 24 is activated to drive the winding magnetic powder brake 24 to rotate. The rotation of the winding magnetic powder brake 24 drives the chain to rotate, and the chain drives the tension controller to rotate, thereby achieving effective control of the operating speed and ensuring that the stripping cloth can be slit at a stable operating speed.

[0027] Since the stripping cloth becomes thinner and thinner during slitting, it is inconvenient for the cutter 12 to contact the stripping cloth. Therefore, after cutting a certain thickness, the electric push rod 6 is started, and the electric push rod 6 will drive the fixed plate 7 to move downward, and the fixed plate 7 moves downward to drive the two support plates 8 to move downward, and the support plate 8 moves downward to drive the bidirectional screw rod 9 to move downward, and the bidirectional screw rod 9 moves downward to drive the wire holder 11 to move downward, and the wire holder 11 moves downward to drive the first hollow connector 13 and the second hollow connector 14 to move downward, and the first hollow connector 13 and the second hollow connector 14 move downward to drive the two cutters 12 to move downward until they move to a suitable position, thereby facilitating cutting;

[0028] In order to adapt to stripping cloths of different widths, the first motor 10 is started through the control area 2. The first motor 10 drives the bidirectional screw 9 to rotate. The rotation of the bidirectional screw 9 drives the wire holder 11 to move in the corresponding direction or in the opposite direction on its surface, thereby driving the two cutters 12 to move closer and farther away, so as to adapt to stripping cloths of different widths.

[0029] As time goes by, the cutter 12 will become blunt due to long-term use and rust, affecting the cutting efficiency. Therefore, by turning the first knob 16 and the second knob 18, the first knob 16 and the second knob 18 will drive the first screw 15 and the second screw 17 to move outside the first hollow connecting member 13 and the second hollow connecting member 14 respectively, thereby driving the arc-shaped limit plate 21 away from the mounting rod 19 until the first screw 15 is away enough to remove the mounting rod 19 from the first hollow connecting member 13, and finally remove the mounting rod 19 from the first hollow connecting member 13 and the second hollow connecting member 14, and then install the new cutter 12 into the first hollow connecting member 13 and the second hollow connecting member 14 according to the reverse operation of the above method.

[0030] Through the above operation, the release cloth can be cut stably and the cutter 12 can be easily replaced.
