Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting, in particular to a cutting assembly and a wire cutting machine. Background Art

[0002] At present, there are many sizes of silicon rods commonly used in the photovoltaic industry. Each size of silicon rod corresponds to a certain specification of the main roller wheelbase of the slicer. Therefore, the corresponding slicer specifications will increase, which greatly increases the cost of production enterprises. In order to improve the applicability of the slicer, a slicer with a variable wheelbase came into being. This slicer adjusts the main roller wheelbase by adjusting the position of the main roller.

[0003] However, when adjusting the wheelbase of a slicer with a variable wheelbase, it is necessary to first stop the machine and remove the wire mesh wound on the main roller, and then adjust the wheelbase of the main roller. After the adjustment is completed, the wire mesh is laid on the main roller before the next step of cutting can be performed. It can be seen that the existing slicer with a variable wheelbase has the problem of long main roller wheelbase adjustment time and low efficiency.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content

[0051] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0052] It should be noted that, in the description of the present application, the terms "upper", "lower", "left", "right", "vertical", "horizontal", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", and "fourth" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "multiple" refers to at least two.

[0053] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0054] As described in the background technology, when adjusting the wheelbase of a variable wheelbase slicer, it is necessary to first stop the machine and remove the wire mesh wrapped around the main roller, and then adjust the wheelbase of the main roller. After the adjustment is completed, the wire mesh is laid on the main roller before the next cutting step can be carried out. This not only prolongs the adjustment time of the wheelbase of the main roller, but also brings about problems such as reduced cutting efficiency.

[0055] In order to solve the problem of long time and low efficiency of adjusting the main roller wheelbase, the cutting assembly of the present application includes a cutting frame, a first main roller assembly and a second main roller assembly. Two first main roller assemblies are provided, and the two ends of each first main roller assembly are respectively adjustably arranged on two opposite side walls of the cutting frame. The second main roller assembly is located on one side of the vertical line between the axes of the two first main roller assemblies, and the two ends of the second main roller assembly are respectively movably arranged on two opposite side walls of the cutting frame along the same straight line direction, wherein there is an angle between the straight line direction and the vertical line.

[0056] For example, in the above arrangement, when the wheelbase between the two first main roller assemblies needs to be reduced, the two first main roller assemblies are first adjusted in a direction close to each other, at which time the tension of the wire web between the two first main roller assemblies and between the first main roller assembly and the second main roller assembly becomes smaller, and in order to prevent the wire web from being derailed, the second main roller assembly is controlled to move in a direction away from the perpendicular line connecting the axes of the two first main roller assemblies, and finally the wheelbase of the two first main roller assemblies is adjusted without being derailed. When the wheelbase between the two first main roller assemblies needs to be increased, it is only necessary to adjust in the opposite direction to the above.

[0057] The above technical scheme, through the adjustable setting of the first main roller assembly and the adjustable setting of the second main roller assembly in the straight direction, can utilize the adjustment action of the first main roller assembly to cooperate with the adjustment action of the second main roller assembly. For example, when the two first main roller assemblies are close to each other, the second main roller assembly is moved in the direction away from the vertical line between the axes of the two first main roller assemblies to maintain the wire net tension and prevent the wire net from being derailed; when the two first main roller assemblies are away from each other, the second main roller assembly is moved in the direction close to the vertical line between the axes of the two first main roller assemblies to maintain the wire net tension and prevent the wire net from being broken; thereby realizing the adjustment of the wheelbase without disassembling the wire net, and the adjustment process can also realize that the tension of the center wire net remains basically unchanged, which not only greatly saves the adjustment time of the main roller wheelbase, but also improves the cutting efficiency, and is suitable for popularization and use.

[0058] It should also be noted that "adjustable" in this application means that the two ends of the first main roller assembly only change in position in the radial direction before and after adjustment, and there is no or almost no position change in the axial direction. The specific method of achieving "adjustable" is not limited in this application, and two examples are given in the following preferred embodiments, respectively, the first main roller assembly changes position after eccentric rotation and linear sliding.

[0059] Refer to the following Figures 1 to 5C , the first preferred implementation of the present application is introduced.

[0060] like Figures 1 to 3 As shown, the cutting assembly includes a cutting frame 1, a first main roller assembly 2, a second main roller assembly 3, a first eccentric sleeve 41, a second eccentric sleeve 42, a third slider 63 and a fourth slider (not shown). The cutting frame 1 has two side walls opposite to each other, one of which has two first mounting holes 11 and a third slide 13, and the other side wall has two second mounting holes and a fourth slide correspondingly. The two first mounting holes 11 are both circular through holes, and the two first mounting holes 11 are arranged horizontally at the upper part of the side wall. The third slide 13 is a strip-shaped through groove, which extends in the vertical direction below the two first mounting holes 11, and the horizontal position is located between the two first mounting holes 11. In this way, the third slide 13 and the two first mounting holes 11 form an inverted triangle arrangement. Similarly, the two second mounting holes are both circular through holes, and the two second mounting holes are arranged horizontally at the upper part of the side wall. The fourth slide groove is a strip-shaped through groove, which extends vertically below the two second mounting holes and is horizontally located between the two second mounting holes. Further, each first mounting hole 11 is concentrically arranged with a second mounting hole, and the third slide groove 13 is arranged correspondingly with the fourth slide groove and their projections overlap.

[0061] The first eccentric sleeve 41 is provided with a first eccentric hole, and the second eccentric sleeve 42 is provided with a second eccentric hole. Preferably, two first eccentric sleeves 41 and two second eccentric sleeves 42 are provided, and the two first eccentric sleeves 41 are respectively installed in the two first mounting holes 11, and the two second eccentric sleeves 42 are respectively installed in the two second mounting holes. After installation, the first eccentric sleeve 41 can rotate relative to the first mounting hole 11, and the second eccentric sleeve 42 can rotate relative to the second mounting hole. Taking the first eccentric sleeve 41 as an example, a connecting hole can be provided on one end face of the first eccentric sleeve 41, and a plurality of screw holes greater than the connecting holes can be provided on the periphery of the first mounting hole 11. After the first eccentric sleeve 41 is rotated, the connecting hole is connected with different screw holes to realize the rotation of the first eccentric sleeve 41; the first eccentric sleeve 41 can also be transitionally matched or clearance matched with the first mounting hole 11 to realize the rotation of the first eccentric sleeve 41. The two ends of each first main roller assembly 2 are respectively installed in the first eccentric hole and the second eccentric hole. Specifically, the first main roller assembly 2 includes a first main roller 23 and a first bearing box 21 and a second bearing box 22 installed at both ends of the first main roller 23. The first bearing box 21 and the second bearing box 22 are respectively installed in a first eccentric sleeve 41 and a second eccentric sleeve 42 corresponding to each other.

[0062] See also Figure 4 The third slider 63 is rectangular as a whole, and a circular third limiting hole 631 is formed in the middle of the plate body. The third limiting hole 631 protrudes from the plate body and is slidably connected to the third slide groove 13. The third limiting hole 631 is a through hole. Similarly, the fourth slider has the same structure as the third slider 63, and the fourth slider is slidably connected to the fourth slide groove. The fourth slider is formed with a fourth limiting hole protruding from the plate body. Taking the third slider 63 as an example, a plurality of through holes can be set on the third slider 63, and a number of screw holes greater than the number of through holes can be set on the periphery of the third slide groove 13. After the third slider 63 slides, the through holes are connected to different screw holes to realize the slidable setting of the third slider 63; for another example, a clamping block can be set on the third slider 63, and a plurality of clamping slots can be set on the third slide groove 13. The position adjustment of the third slider 63 can be realized by changing the clamping position of the clamping block in the third slide groove 13.

[0063] The two ends of the second main roller assembly 3 are respectively mounted on the third slider 63 and the fourth slider. Specifically, the second main roller assembly 3 includes a second main roller 33 and a third bearing box 31 and a fourth bearing box 32 mounted on both ends of the second main roller 33, and the third bearing box 31 and the fourth bearing box 32 are respectively mounted in the third limiting hole 631 and the fourth limiting hole.

[0064] Refer to the following FIG. 5A to FIG. 5C , the process of adjusting the wheelbase in the first embodiment is introduced. It should be noted that, for ease of understanding, the following text is only based on FIG. 5A to FIG. 5CThe side wall of the cutting frame and the components on the side wall are described as an example. Those skilled in the art can understand that the adjustment process of the other side wall is similar to this, so it will not be repeated here.

[0065] like Figures 5A to 5C As shown, when the wheelbase between the two first main roller assemblies 2 needs to be increased, the two first eccentric sleeves 41 are rotated outwards respectively, and the rotation direction is as follows: Figure 5A and Figure 5B As shown, the first eccentric sleeve 41 on the left rotates counterclockwise, and the first eccentric sleeve 41 on the right rotates clockwise. As the rotation process proceeds, the distance between the two first main rollers 23 gradually increases. At this time, the tension of the cutting line between the two first main rollers 23 and the tension of the cutting line between each first main roller 23 and the second main roller 33 are increased. In order to increase the length of the cutting line between the two first main rollers 23 and reduce the tension of the cutting line, the two first main rollers 23 can be controlled to rotate inwards accordingly, that is, the first main roller 23 on the left rotates clockwise, and the first main roller 23 on the right rotates counterclockwise, so as to convey the cutting line between the two first main rollers 23. At the same time, the third slider 63 is moved to drive the second main roller assembly 3 to move upward, so as to convey the cutting line to the cutting area (between the two first main rollers 23), and finally the wheelbase between the two first main rollers 23 is increased, while the total length and tension of the wire web 9 wound on the two first main rollers 23 and the second main roller 33 are kept basically unchanged during the entire adjustment process.

[0066] By providing the first eccentric sleeve 41 and the second eccentric sleeve 42, the rotation position of the first main roller assembly 2 can be adjusted. By providing the third slider 63 and the fourth slider, the linear position of the second main roller assembly 3 can be adjusted. By controlling the synchronous rotation of the first main roller 23 during the adjustment process, the conveying effect of the cutting line can be improved, and the wheelbase adjustment effect can be improved.

[0067] Of course, the above implementations are not set in stone. Without departing from the principles of the present application, those skilled in the art may adjust the above implementations so that the adjusted solutions are suitable for more specific application scenarios.

[0068] For example, although the above embodiment is described in conjunction with the two first main roller assemblies 2 being arranged above the second main roller assembly 3, the specific arrangement positions of the first main roller assembly 2 and the second main roller assembly 3 are not unique, as long as the second main roller assembly 3 can be on one side of the vertical line connecting the axes of the two first main roller assemblies 2. For example, the second main roller assembly 3 can also be above the first main roller assembly 2, or the two first main roller assemblies 2 are arranged in the vertical direction, and the second main roller assembly 3 is located on the left or right side of the two first main roller assemblies 2.

[0069] For another example, although the above embodiment only lists the combination form of the cutting assembly including two first main roller assemblies 2 and one second main roller assembly 3, this is not restrictive. On the premise of ensuring that two first main roller assemblies 2 and one second main roller assembly 3 are provided on the cutting frame 1, those skilled in the art can add other main roller assemblies. For example, an additional third main roller assembly is added between the two first main roller assemblies 2 to achieve double-station processing. For another example, a fourth main roller assembly is added on each of the left and right sides of the second main roller assembly 3 to increase the space in the wire mesh 9.

[0070] For another example, although the first mounting hole 11 and the second mounting hole are described above by taking through holes as an example, the arrangement of the first mounting hole 11 and the second mounting hole is not unique, and those skilled in the art can make adjustments as long as the first eccentric sleeve 41 and the second eccentric sleeve 42 can be effectively installed. For example, one or all of the first mounting hole 11 and the second mounting hole can also be a blind hole or a countersunk hole.

[0071] For another example, it is not necessary to provide the first eccentric hole on the first eccentric sleeve 41 and the second eccentric hole on the second eccentric sleeve 42. In other embodiments, the first eccentric hole or the second eccentric hole can be replaced by an eccentric groove, an eccentric bracket, etc.

[0072] For another example, although the third slide groove 13 and the fourth slide groove are described in combination with the through groove as an example, the specific structural forms of the two are not unique, and those skilled in the art can adjust them as long as the sliding of the third slider 63 and the fourth slider can be effectively achieved. For example, one or both of them can also be replaced by a sink or a slide rail.

[0073] For another example, the third limiting hole 631 and the fourth limiting hole are introduced by taking the protruding plate body as an example, but their specific structural forms are not restrictive. In other embodiments, the third limiting hole 631 and the fourth limiting hole can also be set as a groove, or set flush with the plate body, and the shape can also be replaced with a square, oval, etc., as long as it matches the outer side of the bearing box.

[0074] For another example, although the rotational position adjustment is achieved by rotating the first eccentric sleeve 41 and the second eccentric sleeve 42 at both ends of the first main roller assembly 2 in the above-mentioned embodiment, this is not restrictive, and the position adjustment of the two ends of the first main roller assembly 2 can also be achieved by other means. For example, the first bearing box 21 and the second bearing box 22 at both ends of the first main roller assembly 2 can be set as eccentric bearing boxes, and the position adjustment of the first main roller assembly 2 can be achieved by rotating the first bearing box 21 and the second bearing box 22.

[0075] Similarly, the adjustment method of the second main roller assembly 3 does not necessarily require the use of the third slider 63 and the fourth slider. In other embodiments, the third bearing box 31 and the fourth bearing box 32 can also be slidably set in the third slide groove 13 and the fourth slide groove to achieve linear adjustment of the second main roller assembly 3.

[0076] Combine the following Figure 6 , the second implementation method of the present application is introduced.

The first driving unit 5 is used to drive the two first eccentric sleeves 41 to rotate in opposite directions, and the second driving unit is used to drive the two second eccentric sleeves 42 to rotate in opposite directions. The fifth driving device 8 is used to drive the third slider 63 to slide in a straight line direction, and the sixth driving device is used to drive the fourth slider to slide in a straight line direction.

[0078] Specifically, the first driving part 5 includes two first driving devices 51, each of which is connected to a first eccentric sleeve 41, and is used to drive the first eccentric sleeve 41 to rotate. More specifically, the first driving device 51 includes a first driving motor 511 and a first transmission assembly 512, the first driving motor 511 is fixedly connected to the cutting frame 1, the first driving motor 511 is connected to the first transmission assembly 512, and the first transmission assembly 512 is connected to the first eccentric sleeve 41. Preferably, the first transmission assembly 512 is a gear, and the outer peripheral side of the first eccentric sleeve 41 is provided with a toothed structure meshing with the gear. Similarly, the second driving part includes two second driving devices, each of which is connected to a second eccentric sleeve 42, and is used to drive the second eccentric sleeve 42 to rotate. The second driving device includes a second driving motor and a second transmission assembly, the second driving motor is fixedly connected to the cutting frame 1, the second driving motor is connected to the second transmission assembly, and the second transmission assembly is connected to the second eccentric sleeve 42.

[0079] The fifth drive device 8 includes a fifth drive motor 81 and a fifth transmission assembly 82. The fifth drive motor 81 is fixedly connected to the cutting frame 1, and the fifth drive motor 81 is connected to the fifth transmission assembly 82, and the fifth transmission assembly 82 is connected to the third slider 63. Preferably, the fifth transmission assembly 82 is a screw nut assembly, the screw in the screw nut assembly is connected to the fifth drive motor 81, and the nut in the screw nut assembly is connected to the third slider 63. Similarly, the sixth drive device includes a sixth drive motor and a sixth transmission assembly, the sixth drive motor is fixedly connected to the cutting frame 1, the sixth drive motor is connected to the sixth transmission assembly, and the sixth transmission assembly is connected to the fourth slider. Among them, the sixth transmission assembly is a screw nut assembly, the screw in the screw nut assembly is connected to the sixth drive motor, and the nut in the screw nut assembly is connected to the fourth slider.

[0081] By providing the first drive unit 5 and the second drive unit, the first eccentric sleeve 41 and the second eccentric sleeve 42 can be automatically adjusted, the degree of automation is improved, and it is beneficial to further reduce the adjustment time of the main roller wheelbase.

[0082] Of course, the above-mentioned configuration is merely exemplary. Without departing from the principles of the present application, those skilled in the art may adjust the above-mentioned configuration so that the present application is applicable to more specific application scenarios.

[0083] For example, although the first drive unit 5 is described in combination with two first drive devices 51, and the second drive unit is described in combination with two second drive devices, the specific composition of the first drive unit 5 and the second drive unit is not unique. In other embodiments, the first drive device 51 can simultaneously drive the two first eccentric sleeves 41, and the second drive device can simultaneously drive the two second eccentric sleeves 42. For example, the first drive motor 511 drives the two first eccentric sleeves 41 by driving multiple gears at the same time. For another example, the configuration of the first drive unit 5 and the second drive unit can be the same or different.

[0084] For another example, although the first transmission assembly 512 and the second transmission assembly in the above embodiment are both described by taking gears as an example, the transmission mode is not fixed, and in other embodiments, any transmission assembly that can drive the first eccentric sleeve 41 and the second eccentric sleeve 42 to rotate can be applied to the present application. For example, at least one of the first transmission assembly 512 and the second transmission assembly can also be replaced by a gear rack assembly, a worm gear assembly, a pulley assembly, a sprocket assembly, etc.

[0085] For another example, although the fifth drive device 8 is described in combination with the fifth drive motor 81 and the fifth transmission assembly 82, and the sixth drive device is described in combination with the sixth drive motor and the sixth transmission assembly, the specific structural forms of the fifth drive device 8 and the sixth drive device are not unique. In other embodiments, a linear motor, a hydraulic cylinder, a pneumatic cylinder, etc. can also be used to directly drive the third slider 63 or the fourth slider.

[0086] For another example, although the above-mentioned embodiment is introduced in conjunction with the fifth transmission assembly 82 and the sixth transmission assembly being both screw-nut assemblies, the specific structural forms of the fifth transmission assembly 82 and the sixth transmission assembly are not fixed. In other embodiments, those skilled in the art may also adopt a rack and pinion assembly, a sprocket assembly, etc. as a transmission assembly.

[0087] Refer to the following 7A to 7C , the third implementation mode of the present application is introduced.

[0088] like Fig. 7AAs shown, in the third embodiment, compared with the first embodiment, the difference is that the two first main roller assemblies 2 are adjusted in position by sliders. Specifically, the cutting assembly includes two first sliders 61 and two second sliders, two first slide grooves 12 are provided on one side wall of the two opposite side walls of the cutting frame 1, and two second slide grooves are provided on the other side wall, the two first sliders 61 are respectively slidably connected to the two first slide grooves 12, and the two second sliders are respectively slidably connected to the two second slide grooves, and the two ends of each first main roller assembly 2 are respectively installed on a first slider 61 and a second slider corresponding to each other. In this way, the linear position adjustment of the first main roller assembly 2 can be achieved by sliding the first slider 61 and the second slider.

[0089] Specifically, the two first slide grooves 12 are both bar-shaped through grooves, which are arranged in the horizontal direction and extend in the horizontal direction. The two second slide grooves are respectively arranged corresponding to the two first slide grooves 12 and their projections overlap. A first limiting hole is provided on each first slider 61, and a second limiting hole is provided on each second slider. The two ends of each first main roller assembly 2 are respectively installed in the first limiting hole and the second limiting hole. The setting method of the first slider 61 and the second slider can refer to the third slider 63 in the first embodiment mentioned above, and will not be repeated in this embodiment. In the two first main roller assemblies 2, the first bearing box 21 and the second middle bearing box at both ends of each first main roller assembly 2 are respectively installed in a first slider 61 and a second slider.

[0090] Refer to the following 7A to 7C , the process of adjusting the wheelbase in the first embodiment is introduced. It should be noted that, for ease of understanding, the following text is only based on 7A to 7C The side wall of the cutting frame and the components on the side wall are described as an example. Those skilled in the art can understand that the adjustment process of the other side wall is similar to this, so it will not be repeated here.

[0091] like Figures 7A to 7C As shown, when the wheelbase between the two first main roller assemblies 2 needs to be increased, the two first sliders 61 are moved outwards respectively, and the moving directions are as follows: Fig. 7A and Figure 7BAs shown, the first slider 61 on the left side moves to the left, and the first slider 61 on the right side moves to the right. With the movement of the first slider 61, the distance between the two first main rollers 23 gradually increases. At this time, the tension of the cutting line between the two first main rollers 23 and the tension of the cutting line between the first main roller 23 and the second main roller 33 are increased. In order to increase the length of the cutting line between the two first main rollers 23 and reduce the tension of the cutting line, the two first main rollers 23 can be controlled to rotate inwards accordingly, that is, the first main roller 23 on the left side rotates clockwise, and the first main roller 23 on the right side rotates counterclockwise, so as to convey the cutting line between the two first main rollers 23. At the same time, the third slider 63 is moved to drive the second main roller assembly 3 to move upward, so as to convey the cutting line to the cutting area (between the two first main rollers 23), and finally the wheelbase between the two first main rollers 23 is increased, while the total length and tension of the wire web 9 wound on the two first main rollers 23 and the second main roller 33 are kept basically unchanged during the entire adjustment process.

[0092] Next, refer to Figure 8 , the fourth implementation method of the present application is introduced.

[0093] like Figure 8 As shown, in the fourth embodiment, compared with the second embodiment, since the adjustment mode of the two first main roller assemblies 2 is adjusted to a slider, the driving mode is adaptively adjusted. Specifically, the cutting assembly also includes a third driving unit and a fourth driving unit, the third driving unit is used to drive the two first sliders 61 to slide in opposite directions, and the fourth driving unit is used to drive the two second sliders to slide in opposite directions.

[0094] The third driving part includes a third driving device 71, which is connected to the two first sliders 61 at the same time; the fourth driving part includes a fourth driving device, which is connected to the two second sliders at the same time. The third driving device 71 includes a third driving motor 711 and a third transmission assembly 712, which is fixedly connected to the cutting frame 1, connected to the third driving motor 711 and the third transmission assembly 712, and connected to the two first sliders 61 at the same time. Preferably, the third transmission assembly 712 is a lead screw nut assembly, wherein two lead screws are provided in the lead screw nut, and the two lead screws have opposite rotation directions, one end of one lead screw is connected to the third driving motor 711, and the other end is connected to the other lead screw. A nut is provided on each of the two lead screws, and the two nuts are connected to the two first sliders 61 respectively. Similarly, the fourth driving device includes a fourth driving motor and a fourth transmission assembly, which is fixedly connected to the cutting frame 1, connected to the fourth transmission assembly, and connected to the two second sliders at the same time. Preferably, the fourth transmission assembly is a screw-nut assembly, which includes two screws and two nuts, the two screws have different rotation directions, the two nuts are respectively connected to the two screws, and each nut is connected to a second slider. In this way, when moving the two first sliders 61 or the two second sliders, the third drive motor 711 or the fourth drive motor simultaneously drives the two screws with opposite rotation directions to rotate, so that the two nuts move in opposite directions, and finally realize the movement of the two first sliders 61 or the two second sliders.

[0095] By providing the third driving unit and the fourth driving unit, the first slider 61 and the second slider can be automatically adjusted, the degree of automation can be improved, and the adjustment time of the main roller wheelbase can be further reduced. By using the third driving device 71 to drive the first slider 61 at the same time and using the fourth driving device to drive the second slider at the same time, the synchronization of the movements of the first slider 61 and the second slider can be improved, which is conducive to improving the wheelbase adjustment effect.

[0096] Of course, the method of using one drive motor to drive the two sliders to move at the same time is only exemplary, and those skilled in the art can adjust it without departing from the principle of the present application. For example, two independent drive motors can be set to drive the two first sliders 61 or the two second sliders respectively.

[0097] The present application also provides a wire cutting machine, which includes the above-mentioned cutting assembly. Preferably, the wire cutting machine is a slicer. Of course, in addition to the slicer, the cutting assembly of the present application is also applicable to other wire cutting equipment, such as a mortar machine, etc.

[0098] The wire cutting machine of the present application, by setting the above-mentioned cutting assembly, can adjust the main roller wheelbase without disassembling the wire mesh 9, and the tension of the wire mesh 9 remains basically unchanged during the adjustment process. This can not only greatly reduce the adjustment time and improve the cutting efficiency, but also is suitable for popularization and use.
