Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0027] It should be further explained that the drawings and implementation modes of the present invention mainly describe the concept of the present invention. On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above-mentioned specific forms and settings in a well-known manner.

[0028] When an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

[0029] The directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself. The directions or positional relationships indicated by the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0030] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0032] The single-wire cutting equipment for bar processing provided by the present invention is now described.

[0033] like Figures 1 to 3 As shown, one embodiment of the present invention provides a single-wire cutting device for bar processing, including a machine body 1 and a slide 2 slidably arranged on the machine body 1, the slide 2 is slidably connected to two conveying tables 3, the two conveying tables 3 are rotatably connected to inclined conveying rollers 31, and the two conveying rollers 31 are arranged in a V shape; two support tables 4 parallel to the conveying tables 3 are slidably connected to the slide 2, and the top surfaces of the two support tables 4 are arranged in a V shape; a fixing mechanism 5 for pressing and fixing the silicon rods to the two support tables 4 is arranged on the support table 4; a segmented driving mechanism 6 for driving the two conveying tables 3 to move closer to or away from each other and for driving the two support tables 4 to move closer to or away from each other is arranged on the slide 2, and the movement of the conveying table 3 and the movement of the support table 4 are not performed simultaneously.

[0034] Compared with the prior art, the single-wire cutting equipment for rod processing provided in this embodiment first supports and pushes the silicon rod through two conveying rollers 31. After the support position of the silicon rod is adjusted, the two support platforms 4 are driven to approach each other and support the silicon rod through the segmented driving mechanism 6. The segmented driving mechanism 6 then drives the two conveying platforms 3 away from each other to separate the conveying rollers 31 from the silicon rod. At this time, the fixing mechanism 5 presses the silicon rod against the two support platforms 4 to fix it, and the slide 2 can drive the silicon rod to move to the cutting position for subsequent operations. The fixation of the silicon rod will neither cause pressure and damage to the conveying rollers 31, nor is there a need to set a fixing structure for the silicon rod on the top of the machine body 1, thereby reducing the space occupied by the machine body 1.

[0035] like Figure 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0036] The fixing mechanism 5 includes a connecting screw 51, an automatic connecting and separating component 52, a movable frame 53, a pressing plate 54 and a driving component 55. The connecting screw 51 is rotatably connected to the two support platforms 4. The connecting screw 51 is divided into two sections with opposite thread rotation directions by the position between the two support platforms 4. The automatic connecting and separating component 52 is arranged at the ends of the two sections of the connecting screw 51 that are close to each other. The automatic connecting and separating component 52 is used to automatically connect or automatically separate the two end connecting screws 51 when the two support platforms 4 are close to or away from each other; the movable frame 53 has two corresponding connecting screws 51 that are threadedly connected to different sections. The two movable frames 53 are slidably connected to the support platforms 4 and are located on the outsides of the two support platforms 4. The pressing plate 54 is arranged on the top of the movable frame 53 and is used to press the silicon rod; the driving component 55 is arranged in one of the support platforms 4 and is used to drive the connecting screw 51 to rotate.

[0037] When the segmented driving mechanism 6 drives the two support platforms 4 to approach each other to the supporting position, the automatic connection and separation component 52 enables the two sections of the connecting screw 51 to be automatically connected. At this time, the driving component 55 drives the connecting screw 51 to rotate, so that the two movable frames 53 can approach each other. The two pressing plates 54 press and fix the silicon rods on the support platforms 4. Only one motor is needed to achieve the pressing force on the silicon rods in two directions, thereby improving the pressing and fixing effect of the silicon rods.

[0038] like Figure 2 and Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0039] The automatic connection and separation component 52 includes a rectangular block-shaped connecting portion 521 and an inserting portion 522 with a groove. The connecting portion 521 is arranged on the end face of one of the connecting screws 51, and the inserting portion 522 is arranged on the end face of the other connecting screw 51; the groove on the inserting portion 522 is for the connecting portion 521 to be inserted.

[0040] When the segmented driving mechanism 6 drives the two support platforms 4 to approach each other, the connecting part 521 is automatically inserted into the plug-in part 522, thereby realizing the automatic connection of the two connecting screws 51; when the segmented driving mechanism 6 drives the two support platforms 4 to move away from each other, the connecting part 521 is automatically separated from the plug-in part 522, thereby realizing the automatic separation of the two connecting screws 51, thereby improving the convenience of operation.

[0041] Furthermore, in this embodiment, the outer end of the connecting portion 521 may be in a pointed cone shape, so that it can be automatically inserted into the plug-in portion 522 more conveniently.

[0042] like Figure 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0043] The pressing plate 54 is rotatably connected to the top of the moving frame 53 , and the bottom surface of the pressing plate 54 is inclined toward the top surface of the supporting platform 4 opposite thereto.

[0044] The rotatably connected pressing plate 54 can automatically adjust its angle according to the position where it is pressed on the silicon rod, so that the direction of the force applied to the silicon rod is better.

[0045] like Figure 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0046] The driving component 55 includes a fixed motor 551 and a first gear set 552. The fixed motor 551 is installed in one of the support platforms 4. The first gear set 552 is connected between the output shaft of the fixed motor 551 and the connecting screw 51. Specifically, in this embodiment, the first gear set 552 includes two gears meshing with each other, one of which is coaxially fixed on the output shaft of the fixed motor 551, and the other is coaxially fixed on the connecting screw 51.

[0047] By starting the driving motor 62 , the connecting screw 51 can be driven to rotate through the first gear set 552 , which has a simple structure and is easy to operate.

[0048] like Figure 5 and Figure 6 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0049] The segmented driving mechanism 6 includes a driving screw 61, a driving motor 62, a driving block 63, two adjusting screws 64 and two sets of transmission components 65. The slide 2 is provided with a receiving chamber 21. The driving screw 61 and the adjusting screw 64 are both rotatably connected in the receiving chamber 21 and are parallel to each other. The driving screw 61 is located between the two adjusting screws 64. The adjusting screw 64 is divided into two sections of threads with opposite rotation directions from its middle part. The two conveying platforms 3 and the two supporting platforms 4 are correspondingly threadedly connected to the threads of the adjusting screw 64 with different rotation directions. The driving motor 62 is provided On the slide 2 and connected to the driving screw 61; the driving block 63 is slidably connected in the accommodating chamber 21 and is threadedly connected to the driving screw 61, and the driving screw 61 is divided into a transmission section 611 and a support section 612 by its middle part; the transmission assembly 65 is arranged between the driving block 63 and the corresponding adjusting screw 64; when the driving block 63 moves on the transmission section 611, one of the transmission assemblies 65 drives the corresponding adjusting screw 64 to rotate; when the driving block 63 moves on the supporting section 612, the other transmission assembly 65 drives the corresponding adjusting screw 64 to rotate.

[0050] Specifically, in this embodiment, the portion of the driving screw 61 close to the driving motor 62 is the supporting section 612 , and the portion away from the driving motor 62 is the conveying section 611 .

[0051] When the conveying roller 31 supports the silicon rod, the driving block 63 is located at one end of the support section 612 close to the driving motor 62. When the driving motor 62 is started to rotate the driving screw 61, the driving block 63 moves in a direction away from the driving motor 62. At this time, the driving block 63 drives the adjusting screw 64 on the supporting platform 4 to rotate through the transmission component 65, so that the two supporting platforms 4 are close to each other. When the driving block 63 is separated from the supporting section 612, the two supporting platforms 4 have completed the support of the silicon rod. When the driving block 63 continues to move to the supporting section 612, it starts to drive the adjusting screw 64 on the conveying platform 3 to rotate through another set of transmission components 65, so that the two conveying platforms 3 are separated from the silicon rod. During the whole process, the driving motor 62 only needs to rotate in one direction.

[0052] After the silicon rod is cut, when the next silicon rod needs to be pushed and supported, the driving motor 62 is reversed again to make the driving block 63 move toward the driving motor 62 on the conveying section 611. At this time, the two conveying tables 3 are close to each other, so that the two conveying rollers 31 are reset to the supporting position again; after the driving block 63 returns to the conveying section 611 from the supporting section 612, the two supporting tables 4 are moved away from each other, and the next silicon rod can be placed on the transmission roller for pushing. The whole only needs one motor to perform a single rotation at a long interval to realize the relative sliding of the two conveying tables 3 and the two supporting tables 4 in different time periods, which is convenient and efficient to operate.

[0053] like Figures 5 and 6 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0054] The transmission assembly 65 includes a transmission screw 651, a transmission gear column 652, a driving gear 653 and a second gear group 654. The transmission screw 651 is rotatably connected in the accommodating chamber 21 and is located parallel to the driving screw 61 and the corresponding adjusting screw 64; the transmission gear column 652 is coaxially fixed on the corresponding transmission screw 651, and the transmission gear columns 652 in the two groups of transmission assemblies 65 are correspondingly facing the transmission section or the supporting section 612; the driving gear 653 is slidably connected to the driving screw 61 along the axial direction of the driving screw 61 and is rotatably connected to the driving block 63. The distance between the end faces of the two transmission gear columns 652 that are close to each other is greater than the width of the driving gear 653. When the driving gear 653 rotates and moves to the end face of the transmission gear column 652, it automatically meshes with the transmission gear column 652; the second gear group 654 is connected between the transmission screw 651 and the corresponding adjusting screw 64, and the second gear group 654 is used to drive the adjusting screw 64 to rotate when the transmission screw 651 rotates.

[0055] Specifically, in this embodiment, a slide groove can be opened on the driving screw 61 along its axial direction, and a slider can be fixed on the inner circumference of the driving gear 653 so that the slider slides in the slide groove to improve the stability of the driving gear 653 following the movement of the driving block 63 and the rotation of the driving screw 61.

[0056] When the conveying roller 31 supports the silicon rod, the driving block 63 is located on the conveying section 611 at one end close to the driving motor 62 , and at this time, the driving gear 653 is meshed with the transmission gear column 652 close to the supporting platform 4 .

[0057] After the silicon rod support position is adjusted, when the silicon rod needs to be fixed, the driving motor 62 is started to move the driving block 63 in the direction away from the driving motor 62, and the driving gear 653 drives the transmission gear column 652 close to the support platform 4 to rotate, so that the transmission screw 651 drives the adjustment screw 64 on the support platform 4 to rotate through the second gear set 654, so that the two support platforms 4 are close to each other. When the driving motor 62 drives the driving block 63 to continue to move to the conveying section 611, the driving gear 653 automatically meshes with the transmission gear column 652 close to the conveying platform 3 and drives it to rotate, so that the transmission screw 651 drives the adjustment screw 64 on the conveying platform 3 to rotate through the second gear set 654, so that the two support platforms 4 are away from each other. At this time, the silicon rod can be pressed and fixed to the two support platforms 4 by the fixing mechanism 5. And the self-locking property of the thread can keep the stability of the conveying roller 31 or the support platform 4 when the driving gear 653 and the transmission gear column 652 are not meshed.

[0058] Furthermore, the second gear set 654 includes two gears coaxially fixed on the transmission screw 651 and the adjusting screw 64 and meshing with each other. The outer diameter of the gear located on the transmission screw 651 is smaller than the outer diameter of the transmission gear column 652. The second gear set 654 is located between the end faces of the two transmission gear columns 652 that are close to each other.

[0059] When the transmission gear rotates, the adjusting screw 64 is driven to rotate through the second gear set 654. The structure is simple and the transmission efficiency is high. The outer diameter setting of the gear on the transmission screw 651 can make the driving gear 653 pass between the two transmission gear columns 652 more smoothly.

[0060] Furthermore, both end surfaces of each tooth on the driving gear 653 are conical, which enables the driving gear 653 to mesh with the corresponding transmission gear column more conveniently and accurately when the driving block 63 moves to the transmission section 611 or moves back to the support section 612.

[0061] Furthermore, a bearing 631 is provided between the driving gear 653 and the driving block 63 , so that the movement and rotation of the driving gear 653 can be easier and more stable.
