Description

Technical Field

[0001] The present invention relates to a multi-wire cutting machine, in particular to a multi-wire cutting machine with a one-way movement. Background Art

[0002] On the left and right sides of the frame of a conventional multi-wire cutting machine, a wire take-up roller and a wire pay-off roller are respectively arranged. The multi-wire cutting machine uses a device for the high-speed reciprocating movement of the cutting wire, and this device simultaneously cuts the material to be cut into hundreds of sheet-like structures. This cutting and processing technology is widely used in the stone industry. The conventional multi-wire cutting machine has the following defects: 1. Since the motor in the multi-wire cutting machine needs to drive the cutting wire to perform reciprocating start-stop movements, the power consumption of the motor is relatively large and the load requirement for the motor is relatively high, resulting in a relatively high cost of the motor.

[0003] 2. Since the cutting wire is wound on the wire take-up roller and the wire pay-off roller, and the cutting wire is randomly arranged in the axial direction of the roller, an axial movement of the wire arranging mechanism is required to smoothly guide the cutting wire into the circumferential groove of the cutting roller, which results in a relatively high manufacturing cost of the multi-wire cutting machine.

[0004] In summary, how to reduce the energy consumption during the operation of the multi-wire cutting machine and reduce the manufacturing cost has become an urgent problem to be solved by researchers in this field. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: how to reduce the energy consumption during the operation of the multi-wire cutting machine and reduce the manufacturing cost; To solve the above technical problem, the technical solution adopted by the present invention is: The present invention is a multi-wire cutting machine with a one-way movement, including: a cutting frame; a plurality of cutting rollers arranged in parallel, which are rotationally arranged on the cutting frame under the control of a first motor; a wire storage frame, which is arranged on one side outside the cutting frame; at least two wire storage rollers, which are rotationally arranged on the wire storage frame; a single cutting wire, which sequentially passes around the second circumferential grooves of a plurality of the cutting rollers and is led out by a first single wire, and then sequentially passes around a plurality of the wire storage rollers and is led out by a second single wire, and then is connected end to end with the cutting wire on the cutting roller; the cutting wire between adjacent cutting rollers forms a cutting mesh surface.

[0006] Further, at least one side of the cutting frame is provided with a tensioning mechanism for tensioning the cutting wire.

[0007] Further, each of the wire storage rollers is configured with a second motor for driving its rotation.

[0008] Further, a plurality of first circumferential grooves for accommodating the cutting wire are formed in the cutting roller along its axial direction; a plurality of second circumferential grooves for accommodating the cutting wire are formed in the wire storage roller along its axial direction; the groove pitch between adjacent second circumferential grooves is smaller than the groove pitch between adjacent first circumferential grooves.

[0009] Further, the first circumferential groove at the end of the cutting roller and the second circumferential groove at the end of the wire storage roller are in the same plane.

[0010] Further, a plurality of the wire storage rollers are arranged in pairs, and the cutting wires on the adjacent wire storage rollers arranged in pairs are connected by a third single wire.

[0011] Advantages of the present invention: The present invention is a multi-wire cutting machine with unidirectional movement. In this application, the arrangement of the wire storage roller is adopted to replace the original arrangement of the wire take-up roller and the wire pay-off roller. During the cutting process of the device, the wire storage roller and the cutting roller rotate synchronously and unidirectionally, and the rotation speeds of the plurality of cutting rollers are fixed. Therefore, the first motor does not need to start, stop, rotate forward and backward during the rotation process, reducing the load and power consumption of the first motor. The first motor can drive the cutting roller to rotate by using a low-cost stepping motor. Description of the Drawings

[0012] The present invention will be further described below in conjunction with the drawings and embodiments.

[0013] Figure 1 is a schematic structural diagram of the present invention; Figure 2 is a schematic diagram of another structure of the present invention; Figure 3 is a schematic structural diagram of the cutting roller and the wire storage roller. Detailed Description of the Invention

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0015] As Figure 1 shown, it is a schematic structural diagram of the present application. The cutting frame 1 in the figure is a frame structure. Two cutting rollers 2 are respectively arranged at the upper left and right positions above the cutting frame 1, and two cutting rollers 2 are respectively arranged at the lower left and right positions below. There are a total of four cutting rollers 2. The cutting rollers 2 are connected to the corresponding first motor (not shown). The four cutting rollers 2 are connected into a rectangular structure, and a cutting wire 3 is wound around the four cutting rollers 2; a cutting wire 3 between the two lower cutting rollers 2 forms a cutting mesh surface 4.

[0016] On the left side outside the cutting frame 1, a wire storage frame 5 is provided. Two wire storage rollers 6 are rotatably arranged on the wire storage frame 5. The cutting wire 3 is wound in the second circumferential grooves of the two wire storage rollers 6. The position of the cutting wire 3 on the wire storage rollers 6 is defined by the second circumferential grooves, which is different from the random distribution of the cutting wire on the wire storage rollers or pay-off rollers in traditional multi-wire cutting machines. The leading end of the cutting wire 3 wound on the wire storage roller 6 is connected to the leading end of the cutting wire introduced on the cutting roller 2 (the connection of the leading end and the trailing end here forms the first single wire 31), and the leading end of the cutting wire wound on the wire storage roller 6 is connected to the trailing end of the cutting wire 3 introduced on the cutting roller 2 (the connection of the leading end and the trailing end here forms the second single wire 32).

[0017] The above solution uses the setting of the wire storage rollers 6 to replace the original wire take-up roller and pay-off roller. During the cutting process of this device, the wire storage roller 6 and the cutting roller 2 rotate synchronously in one direction, and the rotation speeds of the four cutting rollers 2 are fixed. Therefore, the first motor does not need to start, stop, rotate forward and backward during the rotation process, reducing the load and power consumption of the first motor. The first motor can use a low-cost stepper motor to drive the cutting roller to rotate.

[0018] As Figure 1 shown, in some possible embodiments, a tensioning mechanism 7 for tensioning the cutting wire 3 is provided on at least one side of the cutting frame 1; In this embodiment, a cutting frame is provided on the right side of the cutting frame 1. The tensioning mechanism 7 is a conventional technology, and its function is to keep the cutting wire 3 on the cutting roller 2 in a tensioned state, which will not be specifically described in this embodiment.

[0019] As Figure 1 shown, in some possible embodiments, each of the wire storage rollers 6 is configured with a second motor for driving its rotation; As Figure 1 shown, in this embodiment, the rotation of the wire storage roller 6 is controlled by the second motor. The synchronous one-way rotation of the multiple wire storage rollers 6 results in relatively low load and power consumption required by the second motor, and it can also be achieved by using a low-cost stepper motor.

[0020] As Figure 3 shown, in some possible embodiments, the cutting roller 2 is provided with a plurality of first circumferential grooves 21 for accommodating the cutting wire along its axial direction; the wire storage roller 6 is provided with a plurality of second circumferential grooves 61 for accommodating the cutting wire 3 along its axial direction; the groove pitch between adjacent second circumferential grooves 61 is smaller than the groove pitch between adjacent first circumferential grooves 61; In this embodiment, on the cutting roller 2 and the wire storage roller 6 with the same axial length, the number of the first circumferential grooves 21 on the cutting roller 2 is less than or equal to the number of the second circumferential grooves 61, so that a longer cutting wire can be stored on the wire storage roller 6, reducing the requirement for the number of wire storage rollers 6.

[0021] As Figure 1 shown, in some possible embodiments, the first circumferential groove 21 at the end of the cutting roller 2 and the second circumferential groove 61 at the end of the wire storage roller 6 are in the same plane; In this embodiment, since there is no wire arranging mechanism on both sides of the cutting frame 1, it is necessary to make the first circumferential groove 21 at the end of the cutting roller 2 and the second circumferential groove 61 at the end of the wire storage roller 6 be in the same plane, so that the first single wire 31 can be smoothly introduced from the second circumferential groove 61 to the first circumferential groove 21, and similarly the second single wire 32 can be smoothly introduced from the first circumferential groove 21 to the second circumferential groove 61. In this process, there is no need to use a wire arranging mechanism; A plurality of first circumferential grooves 21 are provided on the cutting roller 2, and a plurality of second circumferential grooves 61 are provided on the wire storage roller 6. The first circumferential groove 21 at the left end of the cutting roller 2 and the second circumferential groove 61 at the left end of the wire storage roller 6 at the end are correspondingly in the same plane. Similarly, the first circumferential groove 21 at the right end and the second circumferential groove 61 at the right end are in the same plane, so that the first single wire 31 and the second single wire 32 are in the Figure 1 horizontal shape as shown. The first single wire 31 and the second single wire 32 are respectively connected to the second circumferential groove 61 and the first circumferential groove 21 at the left end and the second circumferential groove 61 and the first circumferential groove 21 at the right end.

[0022] As Figure 2 shown, in some possible embodiments, a plurality of the wire storage rollers 6 are arranged in pairs, and the cutting wires 3 on the adjacent pairs of the wire storage rollers 6 are connected by a third single wire 33.

[0023] In this embodiment, two wire storage rollers 6 are in a pair, and there are multiple pairs. This embodiment provides two pairs of wire storage rollers 6, a total of four wire storage rollers 6. After the cutting wire 3 winds around two wire storage rollers 6, it is wound around the other two wire storage rollers 6 through the third single wire 33, and after the winding is completed, it is connected to the end of the cutting wire 3 on the cutting roller 2; it can be understood that in a pair of wire storage rollers 6, the greater the distance between the two wire storage rollers 6, the longer the length of the cutting wire 3 that can be stored.

[0024] Taking the above ideal embodiment based on the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
