Description

Technical Field

[0001] The utility model relates to the technical field of coil processing equipment, in particular to a cutting and winding integrated machine. Background Art

[0002] In the process of processing wire mesh or sheet materials, for the transmission of wire mesh or sheet materials, the tension is often controlled based on a torque controller.

[0003] However, the torque controller is restricted by many factors during operation. For example, the installation shaft of the torque sensor is easily affected by the vibration of the machine, resulting in weak anti-interference ability. Also, for example, the output value of the torque sensor is proportional to the force arm. During long-term use, as the force arm wears, it will directly affect the sensing accuracy of the torque sensor. In addition, when the wire mesh or sheet material is not in a tensioned state, the output value of the torque sensor will be wavy, which will also affect the sensing accuracy of the torque sensor. Summary of the Utility Model

[0004] An embodiment of the present application provides a cutting and winding integrated machine, which can effectively ensure the conveying accuracy of wire mesh or sheet materials during the cutting and winding process, thereby achieving the purpose of ensuring the flat movement of wire mesh or sheet materials, and having strong anti-interference ability.

[0005] An embodiment of the present application provides a cutting and winding integrated machine, including a frame, a traction roller, a supporting roller, a control roller, a cutting knife, and a winding roller. The traction roller is installed in the frame, and a first servo motor for driving the traction roller to rotate is installed on the frame. The control roller includes a front control roller, and the front control roller is rotatably installed on one side of the frame through a first rotating shaft. A first rotary encoder for monitoring the rotation of the first rotating shaft is arranged on the frame, and the first rotary encoder is electrically connected to the first servo motor. The winding roller is installed on the other side of the frame relative to the front control roller, and a second servo motor for driving the winding roller to rotate is installed on the frame. The supporting roller has a plurality of them, and they are respectively installed between the front control roller and the traction roller and between the traction roller and the winding roller. The cutting knife is installed in the frame in a manner that can move up and down directionally, and is located between the traction roller and the winding roller.

[0006] In a possible implementation manner, the control roller further includes a rear control roller, and the rear control roller is rotatably installed on the frame through a second rotating shaft and is located between the cutting knife and the winding roller. A second rotary encoder for monitoring the rotation of the second rotating shaft is arranged on the frame, and the second rotary encoder is electrically connected to the second servo motor.

[0007] In a possible implementation, both the first rotary encoder and the second rotary encoder are mechanical rotary encoders or both are optoelectronic rotary encoders.

[0008] In a possible implementation, the first rotary encoder is an optoelectronic rotary encoder and the second rotary encoder is a mechanical rotary encoder; or the first rotary encoder is a mechanical rotary encoder and the second rotary encoder is an optoelectronic rotary encoder.

[0009] In a possible implementation, the front control roller and the rear control roller are respectively vertically connected to the first rotating shaft and the second rotating shaft through two connecting rods, and the two connecting rods are respectively close to both ends of the first rotating shaft or the second rotating shaft.

[0010] In a possible implementation, there are two winding rollers, and the two winding rollers are symmetrically distributed in the height direction with respect to the traction plane of the traction roller. Two second servo motors for respectively controlling the rotation of the two winding rollers are installed on the frame.

[0011] Beneficial effects: Compared with the prior art, the cutting and winding integrated machine provided by the present application sets a rotary front control roller in front of the traction roller, and at the same time, the frame is also provided with a first rotary encoder for monitoring the first rotating shaft connecting the front control roller. The corresponding digital signal is formed by the displacement or rotation angle of the first rotary encoder and sent to the first servo motor. Thus, the rotation speed of the first servo motor can be controlled by the first rotary encoder instead of the torque sensor, so as to ensure the flat movement of the mesh or sheet material, with high control precision, strong anti-interference ability, not easily affected by machine vibration and the tension of the mesh or sheet material, and can also effectively reduce the installation and use costs;

[0012] Among them, there are two winding rollers and two second servo motors, and the winding rollers are symmetrically distributed in the height direction with respect to the traction plane of the traction roller, so that the winding operation can be carried out by the other winding roller after one winding roller finishes winding, thereby improving the work efficiency.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present utility model.

[0019] It can be understood that the term "one" should be understood as "at least one" or "one or more".

[0020] Reference Figures 1 to 3 , an embodiment of the present application provides a cutting and winding integrated machine, including a frame 10, a traction roller 20, a supporting roller 30, a control roller 40, a cutting knife 50 and a winding roller 60. The traction roller 20 is installed in the frame 10, and a first servo motor 11 for driving the traction roller 20 to rotate is installed on the frame 10, so as to actively traction a web or sheet material 70 to move directionally and at a constant speed through the traction roller 20. The control roller 40 includes a front control roller 41, and the front control roller 41 is rotatably installed on one side of the frame 10 through a first rotating shaft 411. A first rotary encoder 412 for monitoring the rotation of the first rotating shaft 411 is arranged on the frame 10, and at the same time, the first rotary encoder 412 is electrically connected to the first servo motor 11.

[0021] During the conveying process of the mesh material or sheet material 70, the movement of the mesh material or sheet material 70 on the front control roller 41 will cause the front control roller 41 to rotate a certain angle. The rotation angle of the front control roller 41 will be transmitted to the first rotary encoder 412 through the first rotating shaft 411. The first rotary encoder 412 will then convert the corresponding angle information into a digital signal that can be received by the first servo motor 11, thereby actively controlling the rotation speed of the traction roller 20 until the cutting and winding integrated machine reaches a conveying balance, that is, the rotation angle of the front control roller 41 and the rotation speed of the traction roller 20 both remain unchanged. This can ensure that the mesh material or sheet material 70 moves smoothly, is not easily affected by machine vibration and the tension state of the mesh material or sheet material 70, has higher induction accuracy, and there is no problem of arm wear.

[0022] The winding roller 60 is installed on the other side of the frame 10 relative to the front control roller 41. At the same time, a second servo motor 12 for driving the winding roller 60 to rotate is installed on the frame 10, so as to wind the mesh material or sheet material 70 through the winding roller 60. Among them, there are multiple supporting rollers 30, and the multiple supporting rollers 30 are respectively installed between the front control roller 41 and the traction roller 20 and between the traction roller 20 and the winding roller 60, for supporting the mesh material or sheet material to ensure that the mesh material or sheet material 70 can move along a predetermined conveying track. The cutting knife 50 is installed in the frame 10 in a manner that can move up and down directionally and is located between the traction roller 20 and the winding roller 60, for cutting off the mesh material or sheet material 70 after the winding roller 60 finishes winding. The cutting knife 50 can be driven to move up and down by a cylinder, an electric cylinder or a hydraulic cylinder.

[0023] In one embodiment, the control roller 40 further includes a rear control roller 42. The rear control roller 42 is rotatably installed on the frame 10 through a second rotating shaft 421 and is located between the cutting knife 50 and the winding roller 60. At the same time, a second rotary encoder 422 for monitoring the rotation of the second rotating shaft 421 is provided on the frame 10, and the second rotary encoder 422 is electrically connected to the second servo motor 12. In this way, the rotation angle of the rear control roller 42 can be converted into a digital signal that can be received by the second servo motor 12 through the second rotary encoder 422, and then the rotation speed of the winding roller 60 can be controlled through the second servo motor 12. By respectively controlling the rotation speeds of the traction roller 20 and the winding roller 60, the stability and reliability of the movement of the mesh material or sheet material 70 can be further ensured.

[0024] In one embodiment, both the first rotary encoder 412 and the second rotary encoder 422 are mechanical rotary encoders or both are photoelectric rotary encoders.

[0025] In another embodiment, the first rotary encoder 412 is a photoelectric rotary encoder, and the second rotary encoder 422 is a mechanical rotary encoder;

[0026] Alternatively, the first rotary encoder 412 is a mechanical rotary encoder, and the second rotary encoder 422 is a photoelectric rotary encoder.

[0027] The mechanical rotary encoder is used to sense the displacement signal of the rotating shaft, while the photoelectric rotary encoder is used to sense the angle signal of the rotating shaft, both of which can identify the rotation angle of the control roller.

[0028] In one embodiment, the front control roller 41 and the rear control roller 42 are respectively connected to the first rotating shaft 411 and the second rotating shaft 421 vertically through two connecting rods 43, and the two connecting rods 43 are respectively close to the two ends of the first rotating shaft 411 or the second rotating shaft 421. That is to say, the front control roller 41 is vertically connected to the first rotating shaft 411 through two connecting rods 43, and the two connecting rods 43 are respectively close to the two ends of the first rotating shaft 411, and the rear control roller 42 is also vertically connected to the second rotating shaft 421 through two connecting rods 43, and the two connecting rods 43 are also respectively close to the two ends of the second rotating shaft 421, so that the overall structure can be simpler under the premise of ensuring the sensing accuracy of the first rotary encoder 412 and the second rotary encoder 422 to the front control roller 41 and the rear control roller 42, thereby reducing the manufacturing and use costs and facilitating maintenance.

[0029] In one embodiment, there are two winding rollers 60. The two winding rollers 60 are symmetrically distributed in the height direction relative to the traction plane of the traction roller 20, and two second servo motors 12 are installed on the frame 10 for respectively controlling the rotation of the two winding rollers 60. In this way, when one winding roller 60 is wound, the other winding roller 60 can be directly used for winding operation. At the same time, when one winding roller 60 fails, it will not affect the work of the other winding roller 60, thereby ensuring the working efficiency and working reliability of the cutting and winding machine.

[0030] The first servo motor 11 can drive the traction roller 20 to rotate by means of a transmission wheel in combination with a transmission chain or a transmission belt. For example, the rotating shaft sleeve of the first servo motor 11 is provided with a driving wheel, and the traction roller 20 is provided with a transmission wheel, and the driving wheel and the transmission wheel are connected by a transmission belt or a transmission chain, so that the first servo motor 11 can drive the traction roller 20 to rotate in a directional and constant speed to ensure the smoothness of the movement of the web or sheet 70. The second servo motor 12 drives the winding roller 60 to rotate in a similar manner.

[0031] It should be noted that the terms "first" and "second" in this application are only for descriptive purposes, do not represent any order, and should not be construed as indicating or implying relative importance. These terms can be interpreted as names.
