[0002] In the actual application of wires, in order to meet the precise requirements of wire length for various complex projects and products, it is usually necessary to cut the rolled wires into several shorter segments of equal length. This cutting work is crucial to ensuring the quality and performance of wire products. However, the traditional manual cutting method has many shortcomings. First, the wire length is manually measured with a ruler, and then cut with the help of a cutting tool. This method is not only inefficient, but also easily affected by human factors, resulting in errors in the cutting length. Secondly, long-term manual operation will make workers feel tired, increase work intensity, and may even cause work-related accidents. In order to solve these problems, automatic fixed-length cutting equipment for wires has gradually appeared on the market, such as the application publication number CN109676066A, named A fixed-length cutting machine for wires.

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problem that the equipment structure is too complex, resulting in high procurement and maintenance costs, the present invention provides a fixed-length slitting device for linear materials, which can simplify the equipment structure and reduce procurement and maintenance costs.

[0020] It should be noted that the fixed-length slitting device for linear materials described in the present invention is used for but not limited to electric wires, etc. For the convenience of explanation, in the present invention, only the fixed-length slitting device for linear materials applied to electric wires is used as an example for explanation. The principle of applying a fixed-length slitting device for linear materials to other types of equipment is essentially the same as the principle of applying it to electric wires, and will not be elaborated here.

[0021] See also Figure 1-Figure 3 ,in Figure 1Schematic diagram of the structure of a fixed-length slitting device for linear materials in one embodiment of the present invention, a fixed-length slitting device for linear materials includes a support frame 1, a cutting assembly 2 and a power assembly 3, the cutting assembly 2 includes a first driving member 21, a disc 22, a pair of arms 23, a pair of cutters 24, a spring 25 and a pair of round rods 26, the first driving member 21 is connected to the support frame 1, the disc 22 is connected to the first driving member 21 by transmission, the arc surface of the disc 22 is provided with an annular channel 221, one end of the two arms 23 is hinged respectively On both sides of the annular channel 221, the other ends of the two arms 23 are respectively connected to the two cutters 24, and the spring 25 is installed between the two arms 23 so that a part of the two arms 23 protrudes from both sides of the disc 22. The two round rods 26 are provided on both sides of the disc 22 and are used to realize the relative movement of the two arms 23 and the cutting of the two cutters 24 by respectively abutting the protruding parts of the two arms 23 when the disc 22 rotates. The power assembly 3 is located at one end of the disc 22 and is used to drive the linear material into the annular channel 221.

[0022] In this embodiment, the setting of the tool 24 constitutes a shearing structure for linear materials, and the setting of the disc 22 allows the staff to process linear materials of different fixed lengths by simply adjusting the disc 22 to different rotational speeds without changing the speed at which the power component 3 transmits the linear material. Compared with traditional equipment, the device structure of the present invention is simpler, that is, the procurement cost and maintenance cost are lower.

[0023] First, the first driving member 21 drives the disc 22 to rotate, that is, the disc 22 drives the two arms 23 to rotate together; then, during the rotation of the disc 22, the protruding parts of the arms 23 will abut against the round rod 26. Since the two round rods 26 are fixed, the two arms 23 move relative to each other under the pressure of the round rod 26, and then the two cutters 24 can move relative to the thickness direction of the disc 22 until they are closed, that is, the wire between the two cutters 24 is cut.

[0024] It should be noted that the required length of the wire is determined, and the end of the wire is manually brought through the power component 3 and continues to pass through the annular channel 221, with the vertical plane where the round rod 26 is located as the reference point. When the wire is straightened, the distance between the end of the wire and the vertical plane where the round rod 26 is located is the required length, so that the tool 24 can cut the wire exactly on the vertical plane where the round rod 26 is located.

[0025] Furthermore, the first driving member 21 is a servo motor.

[0026] Furthermore, under the premise that the wire moves at a uniform speed, the time it takes for the wire to reach the required length is calculated through the computer according to the required wire length, and the time is fed back to the control end of the first drive member 21. The rotation speed of the disc 22 is regulated by the calculation formula of the PLC computer control end, that is, the circumference of the disc 22 divided by the time is the required rotation speed of the disc 22, and the staff can cut wires of different lengths by adjusting the rotation speed of the disc 22.

[0027] In one embodiment, see Figure 1-Figure 3 Both side walls of the annular channel 221 are provided with mounting grooves 222 , and the bottom surface of the mounting grooves 222 is coplanar with the bottom surface of the annular channel 221 .

[0028] In this embodiment, the arm 23 and the cutter 24 are accommodated in the mounting groove 222 by the provision of the mounting groove 222, thereby reducing the space occupied by the device. Furthermore, the bottom surface of the mounting groove 222 is coplanar with the bottom surface of the annular channel 221, so that the cutter 24 can cut off the wires at any height in the annular channel 221, ensuring that the wires are cut off by the cutter 24.

[0029] In one embodiment, see Figure 1-Figure 3 The top of the round rod 26 is rotatably connected to a guide wheel 261.

[0030] In one embodiment, see Figure 1-Figure 3 The opposite sides of the two arms 23 are provided with an oblique angle 231 , which is adapted to the guide wheel 261 .

[0031] In this embodiment, the function of the guide wheel 261 is to reduce the friction between the bevel 231 and the guide wheel 261 , so that the bevel 231 and the guide wheel 261 contact more smoothly, that is, the cutting tool 24 cuts more smoothly.

[0032] In one embodiment, see Figure 1-Figure 3 A support panel 11 is fixedly connected to the top surface of the support frame 1.

[0033] In this embodiment, the support panel 11 is used to store tools.

[0034] In one embodiment, see Figure 1 and Figure 3 The support panel 11 is provided with a clearance hole 111 , the first driving member 21 is mounted on the bottom surface of the support panel 11 , and the disc 22 passes through the clearance hole 111 and is in transmission connection with the first driving member 21 .

[0035] In this embodiment, the function of the clearance hole 111 is to prevent the height of the disc 22 from being too high, which makes it difficult for the staff to operate. The design of the disc 22 passing through the clearance hole 111 effectively reduces the height of the disc 22. At the same time, it also facilitates the lowering of the axis of the disc 22 below the support panel 11, making it easier for the first drive member 21 to be installed below the support panel 11.

[0036] In one embodiment, see Figure 2 The bottom surface of the supporting panel 11 is fixedly connected to the mounting frame 12 , and the first driving member 21 is fixedly mounted on the mounting frame 12 .

[0037] In this embodiment, the installation of the mounting bracket 12 facilitates the installation of the first driving member 21 below the support panel 11 , thereby providing space for storing more tools above the support panel 11 .

[0038] In one embodiment, see Figure 1 and Figure 2 The power assembly 3 includes a support platform 31, a pair of transmission wheels 32 and a second driving member 33. The support platform 31 is installed on the support panel 11 and is located on one side of the annular channel 221. The two transmission wheels 32 are rotatably connected to the top surface of the support platform 31, and the two transmission wheels 32 are relatively spaced apart. The second driving member 33 is transmission-connected to the transmission wheel 32.

[0039] In this embodiment, the second driving member 33 adopts a small servo motor. The second driving member 33 is connected to the end of one of the transmission wheels 32, and the ends of the two transmission wheels 32 are provided with gears. The two gears are engaged, so that the second driving member 33 can simultaneously drive the two transmission wheels 32 to rotate synchronously, thereby realizing the two transmission wheels 32 driving the wires to move. It should be noted that the two rollers slightly clamp the linear material and drive the linear material to move in a straight line. This is a conventional method in this field, so it will not be elaborated in detail.

[0040] Furthermore, in order to enhance the moving effect of the electric wires, there are more than one pair of transmission wheels 32 , and each pair of transmission wheels 32 is connected by a belt or a chain to achieve synchronous rotation of each pair of transmission wheels 32 .

[0041] Furthermore, the surface of the transmission wheel 32 is frosted, which is convenient for increasing the friction between the transmission wheel 32 and the wire, making the wire smoother during transmission.

[0042] Furthermore, an encoder or meter is installed on the support platform 31 to feedback the length of the wire moved, and the data is connected to the control end of the first drive member 21. The rotation speed of the first drive member 21 is continuously corrected by the data. That is, after the encoder or meter measures the required length, the length divided by the rotation speed of the second drive member 33 is the time taken, and the length of the disk 22 divided by the time required is the rotation speed of the disk 22.

[0043] In one embodiment, see Figure 1-Figure 3 A baffle 34 is provided above the gap between the two transmission wheels 32 .

[0044] In this embodiment, the electric wire is prevented from being separated from between the two transmission wheels 32 .

[0045] In one embodiment, see Figure 2 , the top surface of the support platform 31 is tangent to the top of the annular channel 221 .

[0046] In this embodiment, the electric wires can better enter the annular channel 221 from the support platform 31 , effectively preventing the electric wires from bending during the process of moving into the annular channel 221 .

[0047] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the present invention is described in detail: First, in the initial state, the two cutters 24 are in a closed state under the action of the two guide wheels 261, so that the end of the wire is in contact with the closed position of the two cutters 24, so that the wire takes the closed position of the two cutters 24 as the starting point; then, the second driving member 33 is started, and the wire is continuously moved at a uniform speed toward the annular channel 221 under the action of the uniform rotation of the transmission wheel 32. The time taken to move the required length of wire is calculated by the computer-side PLC, and then the time is converted and programmed by the computer and fed back to the control end of the first driving member 21. Through the regulation of the control end, the time taken by the first driving member 21 to drive the disc 22 to rotate one circle and the time taken to move the wire of the required length are consistent; finally, since the time taken by the two is consistent, the device can automatically cut out a large number of fixed-length wires; It can be seen that, under the premise that the moving speed of the wires is constant, the device of the present invention only needs to adjust the rotation speed of the disc 22. When a large number of longer wires need to be cut, the rotation speed of the disc 22 can be slowed down; conversely, when a large number of shorter wires need to be cut, the rotation speed of the disc 22 can be accelerated, which effectively avoids the labor intensity of manual cutting. At the same time, compared with traditional automatic shearing machines, the device has a simpler structure and lower procurement and maintenance costs.

[0048] The above specific embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
