Description

Technical Field

[0001] The invention relates to the technical field of wire cutting, in particular to a single-wire slicing machine. Background Art

[0002] Machine tools cover two broad categories of materials for machining parts: plastic materials and hard and brittle materials. Machine tools for machining plastic materials are general-purpose metal cutting machines with a wide range of performance capabilities. Machine tools for machining hard and brittle parts are specialized machines (excluding EDM machines) that use diamond tools. These machines also include specialized machines for machining hard and brittle parts using diamond wire tools with slicing capabilities.

[0003] The cutting range of the above-mentioned machine tools with slicing function includes hard and brittle materials such as neodymium iron boron magnetic materials, ferrite magnetic materials, ceramics, crystals, semiconductors, gems, quartz, glass, crystal, precious stones, and cemented carbide. Its development status is as follows:

[0004] 1. The earliest slicers were cylindrical slicers (including multi-blade slicers) that appeared in the 1850s. Due to the thick blades, the processing effect was poor and the cut materials needed to be processed again, resulting in high processing costs and high material waste rate.

[0005] 2. The saw bow multi-strip steel strip slicer uses granular abrasive, which results in low cutting efficiency. In addition, the strip steel strip clamping accuracy is high, which is difficult and labor-intensive.

[0006] 3. In the 1970s, Japan's internal circle slicer was introduced, which greatly improved the processing effect and efficiency. However, one operator could only operate 2-3 machine tools. Since integrated processing is a labor-intensive industry, the machine tools use rough open processing, which causes great pollution to the environment.

[0007] 4. Since the 20th century, fully automatic slicers have been put into the domestic market, performing fully enclosed processing and solving the environmental problems of "three wastes". In addition, one operator can operate 20-30 machine tools, which has promoted the development of integrated processing of hard and brittle materials. There are more than 100,000 such fully automatic slicers in use in China today.

[0008] 5. Mortar steel wire multi-wire slicers have appeared. This type of machine tool is basically used for processing single silicon products for solar energy. Due to environmental pollution, low efficiency, high investment costs and other issues, it has now withdrawn from the market.

[0009] 6. The emergence of multi-wire diamond slicers. Driven by breakthroughs in high-tech micro-particle diamond coating technology, multi-wire diamond slicers have rapidly entered the market for machining hard and brittle parts. Their greatest advantage lies in processing large quantities of products, and the market for this product is currently saturated. Due to the large size and complexity of these machines, and the high investment cost, each machine requires the production of a corresponding cutting roller (commonly known as a "roller") for each product specification. Furthermore, these rollers require high machining precision, resulting in high operating costs. Consequently, this product has been difficult to popularize for small and medium-volume production and small and medium-sized enterprises.

[0010] 7. Diamond wire single-wire slicer. Currently, the slicer technology used in the market is still based on multi-wire slicer technology. The investment and operating costs are difficult to reduce to a level that small and medium-sized enterprises can widely use.

[0011] (1) The retractable wire structure adopts two independent diamond wire synchronous retractable wire structures, so the structure is complex. At the same time, the steel parts of the retractable wire drum need to be customized, and the diamond wire winding on the drum needs to be processed by the diamond wire manufacturer, which is inconvenient to use; each drum of wire weighs about 30 kilograms, has a large rotational inertia, and the supporting drive motor has a large no-load loss;

[0012] (2) The cutting roller process is used for cutting diamond wire, which has a complex structure and must be replaced for each product specification. Replacing the cutting roller requires a special hydraulic tool and the operator must be trained to a qualified level, so the use requirements are high and the operation is inconvenient;

[0013] (3) Due to the large rotational inertia of the reel, tension control is difficult (the diameter of the diamond wire is small), and the control cost of the equipment increases. At the same time, the tension is controlled in an open loop, so the tension control accuracy is relatively low;

[0014] (4) The workbench lifting structure uses a rolling guide and a ball screw, which are installed on the Z axis of the frame. In addition, the horizontal adjustment structure makes the structure complex, which makes it difficult to match the three waste treatment equipment of the shield;

[0015] (5) If the wire is wound on the cutting roller or when the wire is broken, the manual method by the operator (who must be trained and qualified) is difficult, labor-intensive and time-consuming.

[0016] Therefore, the current market for multi-wire and single-wire diamond slicers requires further improvement and innovation to meet the investment and use requirements of small and medium-sized enterprises. Addressing the above five shortcomings and defects of multi-wire and single-wire diamond slicers has become the prerequisite and basis for the development and innovation of this single-wire diamond slicer.

[0017] Moreover, the layout of the functional areas of the current slicer is not reasonable enough, and the operation is inconvenient. Summary of the Invention

[0018] The technical problem to be solved by the present invention is to provide a single-line slicer with reasonable layout of functional areas and convenient use in view of the current status of the existing technology.

[0019] The technical solution adopted by the present invention to solve the above technical problems is: a single-line slicer, including a frame and a cutting line for cutting materials, characterized in that: it also includes

[0020] A drum is rotatably mounted on the frame and is used to wind the cutting wire. The first side of the drum is a first winding side, and the second side of the drum is a second winding side. The first winding side and the second winding side switch back and forth between a wire arrangement state and a wire return state as the direction of rotation of the drum changes.

[0021] A guide wheel assembly is rotatably mounted on the frame and is used to guide the direction of the cutting line, wherein the cutting line passes around the guide wheel assembly to form at least two groups of cutting areas arranged at intervals;

[0022] a tension control mechanism, provided on the frame and linked to the cutting line, for controlling the tension of the cutting line;

[0023] A tension adjustment mechanism is provided on the frame and is linked to the cutting line, and is used to cooperate with the tension control mechanism to adjust the tension of the cutting line;

[0024] A winding mechanism, provided at the rear side of the drum, for winding the cutting wire onto the drum or recovering the waste wire on the drum; and

[0025] The working table can be moved forward and backward and lifted up and down and is arranged below the cutting area.

[0026] The guide wheel assembly includes a corner guide wheel that can divide the cutting line into left and right cutting areas and a steering guide wheel that further divides the two processing areas into four cutting stations.

[0027] Preferably, the winding mechanism includes

[0028] A bobbin is rotatably arranged on one side of the drum;

[0029] a bracket, arranged on the frame;

[0030] An oscillating body is provided on the bracket so as to be able to swing back and forth, and the swing axis of the oscillating body is perpendicular to the axial direction of the drum;

[0031] A guide wheel is rotatably mounted on the oscillating body and oscillates synchronously with the oscillating body, wherein the axis of the guide wheel is parallel to the axial direction of the drum in a static state;

[0032] The outlet end of the cutting line extends from the wire drum and passes around the upper edge of the guide wheel. The guide wheel assembly is constrained on the drum. The cutting line at the top edge of the guide wheel is roughly in the same straight line as the swing center line of the swing body.

[0033] When winding the wire onto the drum, the cutting wire on the wire drum continuously changes its position along the winding direction when the wire is unwound. With the above structure, after the cutting wire passes through the guide wheel, the guide wheel can swing back and forth perpendicular to the axial direction of the drum under the action of the deflection force of the cutting wire. However, during the swinging process, the cutting wire at the top edge of the guide wheel is always colinear with the swinging center line of the swinging body, thereby ensuring that the position of the cutting wire after passing the guide wheel is constant, thereby avoiding the back-line problem when winding the wire onto the drum, thereby improving the winding accuracy and the cutting wire tension stability.

[0034] In the above scheme, the guide wheel assembly includes a first guide wheel, a second guide wheel, a third guide wheel, a fourth guide wheel, and a fifth guide wheel, the axis lines of the first guide wheel, the second guide wheel, the third guide wheel, the fourth guide wheel, and the fifth guide wheel extend forward and backward and are all located in a first vertical plane, the first guide wheel and the second guide wheel are arranged at intervals below the first side of the third guide wheel, the fourth guide wheel and the fifth guide wheel are arranged at intervals below the second side of the third guide wheel and are located on the same straight line as the first guide wheel and the second guide wheel, the cutting line passes through the first guide wheel, the second guide wheel, the third guide wheel, the fourth guide wheel, and the fifth guide wheel in sequence to form a "J"-shaped structure, the first side horizontal side of the "J"-shaped structure is located in the first cutting area and forms a first cutting station, and the second side horizontal side of the "J"-shaped structure is located in the second cutting area and forms a second cutting station. With the above structure, cutting stations are formed in the two cutting areas respectively, and the two cutting areas arranged side by side are arranged adjacent to each other, so that one operator can take care of the work of the two cutting areas at the same time, thereby improving processing efficiency.

[0035] As an improvement, the third guide wheel is mounted on the frame and is positioned at the top of the "J"-shaped structure, allowing it to float up and down. The cutting line is arranged around the upper edge of the third guide wheel, and the frame is provided with an elastic member that enables the third guide wheel to maintain an upward movement trend. The present invention utilizes the third guide wheel to divide a cutting line in the same conveying direction into two cutting stations. When the cutting line is activated or reversed, problems such as uneven tension in various parts of the cutting line and excessive tension in some parts of the cutting line may occur. If the cutting line is partially too loose, it cannot meet the cutting requirements, affecting the cutting quality; if the cutting line is partially too tight, it is very likely to cause the cutting line to break. Using the above structure, when the cutting line is relatively loose, the elastic member drives the third guide wheel to move the cutting line upward by a certain displacement, thereby tensioning the cutting line. When the cutting line is too tight, the third guide wheel is allowed to move downward by a certain displacement under the pull of the cutting line. In other words, the third guide wheel can float up and down with the tension of the cutting line, effectively adjusting the tension of the cutting line in real time, thereby maintaining uniform tension across the cutting line, maintaining a stable cutting force, and preventing line breakage.

[0036] In the above scheme, the tension control mechanism includes the third guide wheel, the tension sensor and the third elastic mechanism. The third elastic mechanism is arranged below the third guide wheel and makes the third guide wheel always maintain the tendency to move upward. The tension sensor is arranged on the third elastic mechanism and the upper end is against the third guide wheel.

[0037] Preferably, the guide wheel assembly further includes a sixth guide wheel, a seventh guide wheel, an eighth guide wheel, a ninth guide wheel, a tenth guide wheel and an eleventh guide wheel, the axis lines of the sixth guide wheel, the eighth guide wheel, the ninth guide wheel and the eleventh guide wheel extend forward and backward and are all located in a second vertical plane, the second vertical plane is located on the rear side of the first vertical plane, the sixth guide wheel corresponds to the first guide wheel arrangement, the seventh guide wheel is arranged above or below the first cutting area and is used to reverse the cutting line between the first guide wheel and the sixth guide wheel, the eighth guide wheel corresponds to the second guide wheel arrangement, the cutting line between the sixth guide wheel and the eighth guide wheel is located in the first cutting area and forms a third cutting station, the ninth guide wheel corresponds to the fifth guide wheel arrangement, the tenth guide wheel is arranged above or below the second cutting area and is used to reverse the cutting line between the fifth guide wheel and the ninth guide wheel, the eleventh guide wheel corresponds to the fourth guide wheel arrangement, the cutting line between the ninth guide wheel and the eleventh guide wheel is located in the second cutting area and forms a fourth cutting station. By adopting the above structure, the direction of the cutting line is cleverly reversed 180°, and the third cutting station is aligned with the first cutting station, and the fourth cutting station is aligned with the second cutting station, which facilitates the simultaneous operation of multiple stations and further improves the processing efficiency; and the four cutting stations are formed by one cutting line, which facilitates the control of the cutting force of each cutting station to be stable and uniform, thereby improving the cutting effect.

[0038] Preferably, the seventh and tenth guide wheels are both located above their corresponding cutting areas with their axis lines arranged vertically. The first end of the cutting line is arranged from front to back in sequence around the outer edge of the first guide wheel, the inner edge of the seventh guide wheel, the outer edge of the sixth guide wheel, and the lower edge of the eighth guide wheel. The second end of the cutting line is arranged from front to back in sequence around the outer edge of the fifth guide wheel, the inner edge of the tenth guide wheel, the outer edge of the ninth guide wheel, and the lower edge of the eleventh guide wheel. This structure not only facilitates the reversal of the cutting line, but also minimizes the length of the cutting line in the reversal area, which is conducive to controlling the overall tension stability of the cutting line.

[0039] Preferably, the first guide wheel is aligned front to back with the sixth guide wheel, and the second guide wheel is aligned front to back with the eighth guide wheel. The fourth guide wheel is aligned front to back with the eleventh guide wheel, and the fifth guide wheel is aligned front to back with the ninth guide wheel. The above structure ensures that the cutting line lengths corresponding to the first, second, third, and fourth cutting stations are consistent, and the cutting forces are consistent and stable. Furthermore, the cutting line of the first cutting station is aligned front to back with the cutting line of the third cutting station, and the cutting line of the second cutting station is aligned front to back with the cutting line of the fourth cutting station. When cutting materials, when the materials correspond to the same front and rear positions, the tension of the cutting line is consistent, and the cutting effect is consistent, thereby improving the consistency of the material cutting effect while maintaining a high cutting effect.

[0040] In order to facilitate winding the cutting line onto the drum, the guide wheel assembly further includes a twelfth guide wheel, a thirteenth guide wheel, and a fourteenth guide wheel. The twelfth guide wheel is provided on a vertical mounting plate and the vertical mounting plate is vertically arranged at the rear side of the second vertical plane. The thirteenth guide wheel is provided on the second vertical plane and is located above the eighth guide wheel, and the inner edge of the thirteenth guide wheel is aligned with the front edge of the twelfth guide wheel. The fourteenth guide wheel is provided on the vertical mounting plate and is located behind and below the twelfth guide wheel. The drum is laterally arranged behind the fourteenth guide wheel. The first end of the cutting line passes through the lower edge of the eighth guide wheel, the inner edge of the thirteenth guide wheel, the front edge and upper edge of the twelfth guide wheel, and the lower edge of the fourteenth guide wheel from front to back and is wound around the upper side of the drum. With the above structure, the cutting line is wound onto the drum without deviation. When the drum rotates forward, the lower side of the drum is the cutting line release side and the upper side of the drum is the cutting line return side. When the drum rotates backward, the upper side of the drum is the cutting line release side and the lower side of the drum is the cutting line release side, so as to achieve stable reciprocating transmission of the cutting line.

[0041] Preferably, the guide wheel assembly further includes a fifteenth guide wheel and a sixteenth guide wheel. The fifteenth guide wheel is mounted on the vertical mounting plate and is located below the twelfth guide wheel. The front edge of the fifteenth guide wheel is aligned with the inner edge of the eleventh guide wheel. The sixteenth guide wheel is mounted on the vertical mounting plate and is located below and behind the fifteenth guide wheel. The second end of the cutting line passes from front to back in sequence around the lower edge and inner edge of the eleventh guide wheel, the front edge and upper edge of the fifteenth guide wheel, and the lower edge of the sixteenth guide wheel, and is wound around the underside of the drum. The above structure is conducive to improving the transmission stability of the cutting line.

[0042] In the above schemes, the tension adjustment mechanism includes a twelfth guide wheel, a fourteenth guide wheel, a first elastic mechanism, and a second elastic mechanism. The twelfth guide wheel and the fourteenth guide wheel are respectively arranged on the frame so as to be movable up and down. The first elastic mechanism is arranged below the twelfth guide wheel and enables the twelfth guide wheel to always maintain a tendency to move upward. The second elastic mechanism is arranged below the fourteenth guide wheel and enables the fourteenth guide wheel to always maintain a tendency to move upward.

[0043] Preferably, the first elastic mechanism, the second elastic mechanism, and the third elastic mechanism have the same structure, each comprising a body, an elastic member, and an adjustment rod. The body is provided with a mounting hole extending vertically therethrough, the elastic member being movably disposed in the mounting hole. The adjustment rod is movably constrained to the lower end of the mounting hole of the body, and the upper end of the adjustment rod abuts against the lower end of the elastic member. The upper end of the elastic member is exposed above the mounting hole and abuts against the lower portion of the corresponding wheel. The first elastic mechanism, the second elastic mechanism, and the third elastic mechanism can provide adjustable displacement within a certain tension range for the cutting line. When the cutting line is relatively loose, the tension is released to drive the corresponding guide wheel to move in the opposite direction of the force of the cutting line, thereby increasing the tension of the cutting line. When the cutting line is too tight, the tension is absorbed to allow the corresponding guide wheel to move in the same direction as the force of the cutting line, thereby reducing the tension of the cutting line. This allows the tension of the cutting line to be adjusted in real time, improves the tension stability of the cutting line, avoids breaking the cutting line, and is also conducive to improving cutting quality.

[0044] Preferably, a pre-set component is disposed above each of the third, twelfth, and fourteenth guide wheels, each capable of cooperating with a corresponding elastic mechanism to set the vertical floating displacement of the corresponding guide wheel. The pre-set component has a telescopic rod that can be extended and retracted to abut against the upper end of the corresponding guide wheel. The pre-set component can be used to set the upper floating limit of the corresponding guide wheel and preset a predetermined value of tension on the cutting line through the elastic mechanism, thereby facilitating the maintenance of a stable cutting line tension.

[0045] A workbench is provided below the cutting area, and the workbench comprises:

[0046] A base is arranged on the frame so as to be movable forward and backward;

[0047] A first driving mechanism, provided on the frame and used to drive the base to move forward and backward;

[0048] An installation box, wherein the lower end of the installation box is arranged on the base, the interior of the installation box is hollow to form an installation cavity, and the upper end of the installation box is provided with an installation opening communicating with the installation cavity;

[0049] A lifting member is inserted into the installation opening of the installation box so as to be lifted up and down, with the upper end always exposed above the installation opening;

[0050] A second driving mechanism is provided in the installation cavity and is used to drive the lifting member to move up and down; and

[0051] A workbench is arranged at the upper end of the lifting member.

[0052] Compared with the prior art, the advantages of the present invention are that the functional areas on the slicer of the present invention are reasonably arranged, convenient to operate and use; and it has multiple cutting areas, which is conducive to improving processing efficiency.

[0074] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0075] In the specification, claims and following embodiments of the present invention, directional words such as "up", "down", "left", "right" and "side" are used, but these directional words only indicate relative position relationships and are not limited to absolute directions. For example, "up" and "down" are not limited to directions opposite to or consistent with the direction of gravity.

[0076] like Figures 1 to 21 As shown, the single-wire slicer of this embodiment includes a frame 1, a cutting wire 2, a roller 3, a guide wheel assembly 4, a tension control mechanism, a winding mechanism 6, a tension adjustment mechanism 7 and a workbench 8.

[0077] Among them, such as Figure 1 As shown, the cutting wire 2 is used to cut the material, and the drum 3 is used to wind the cutting wire 2. The cutting wire 2 in this embodiment is a diamond wire, but of course the cutting wire is not limited to a diamond wire. The drum 3 is rotatably arranged at the rear side of the frame 1, and the drum 3 is arranged horizontally on the left and right sides. The upper side of the drum 3 is the first winding side, and the lower side of the drum 3 is the second winding side. The first winding side and the second winding side switch back and forth between the wire arrangement state and the wire return state as the rotation direction of the drum 3 changes. For example, when the drum 3 rotates in one direction, the upper side of the drum 3 is the wire arrangement side of the cutting wire 2, and the lower side of the drum 3 is the wire return side of the cutting wire 2; when the drum 3 rotates in the opposite direction, the lower side of the drum 3 is the wire arrangement side of the cutting wire 2, and the upper side of the drum 3 is the wire return side of the cutting wire 2. The guide wheel assembly 4 includes multiple guide wheels, each of which is rotatably arranged on the frame 1. The guide wheel assembly 4 is used to guide the direction of the cutting line 2. The cutting line 2 forms a closed loop structure that can reciprocate between the roller 3 and the guide wheel assembly 4. The cutting line 2 bypasses the guide wheel assembly 4 to form at least two groups of cutting areas arranged at intervals.

[0078] The guide wheel assembly 4 of this embodiment first divides the cutting line into two cutting areas on the left and right sides through the corner guide wheel, and then further divides the two processing areas into four cutting stations through the steering guide wheel.

[0079] The axis lines of the first guide wheel 401, the second guide wheel 402, the third guide wheel 403, the fourth guide wheel 404 and the fifth guide wheel 405 extend forward and backward and are all located in the first vertical plane 100. The first vertical plane 100 is parallel to the axial arrangement of the drum 3 and is located on the front side of the drum 3. The third guide wheel 403 is located in the upper middle part of the first vertical plane 100. The first guide wheel 401 and the second guide wheel 402 are arranged at intervals below the left side of the third guide wheel 403. The fourth guide wheel 404 and the fifth guide wheel 405 are arranged at intervals below the right side of the third guide wheel 403 and are located on the same straight line as the first guide wheel 401 and the second guide wheel 402. The cutting line 2 passes around the first guide wheel 401, the second guide wheel 402, the third guide wheel 403, the fourth guide wheel 404 and the fifth guide wheel 405 in sequence to form a "J"-shaped structure. More precisely, the "J"-shaped structure is Shape structure, The first side of the shaped structure is located in the first cutting area 4a and forms a first cutting station 41. The second side of the shaped structure is located in the second cutting area 4b and forms the second cutting station 42. The third guide wheel 403 is arranged on the first vertical plane 100 and is located The cutting line 2 is arranged around the upper edge of the third guide wheel 403 at the top of the shaped structure.

[0080] The axial center lines of the sixth guide wheel 406, the eighth guide wheel 408, the ninth guide wheel 409 and the eleventh guide wheel 411 extend forward and backward and are all located in the second vertical plane 200. The second vertical plane 200 is arranged parallel to the rear side of the first vertical plane 100 and the front side of the roller 3. The sixth guide wheel 406 is arranged corresponding to the first guide wheel 401. The seventh guide wheel 407 is arranged above the first cutting area 4a and is used to reverse the cutting line 2 between the first guide wheel 401 and the sixth guide wheel 406. The eighth guide wheel 408 is arranged corresponding to the second guide wheel 402. The cutting line 2 between the sixth guide wheel 406 and the eighth guide wheel 408 is located in the first cutting area 4a and forms a third cutting station 43. The ninth guide wheel 409 is arranged corresponding to the fifth guide wheel 405, the tenth guide wheel 410 is arranged above the second cutting area 4b and is used to reverse the cutting line 2 between the fifth guide wheel 405 and the ninth guide wheel 409, and the eleventh guide wheel 411 is arranged corresponding to the fourth guide wheel 404. The cutting line 2 between the ninth guide wheel 409 and the eleventh guide wheel 411 is located in the second cutting area 4b and forms the fourth cutting station 44. The seventh guide wheel 407 and the tenth guide wheel 410 of this embodiment are both located above the corresponding cutting area and arranged with their axis vertically. Of course, the seventh guide wheel 407 and the tenth guide wheel 410 can also be located below the corresponding cutting area, as long as the corresponding front and rear cutting lines 2 can be reversed. The first end of the cutting line 2 passes, from front to back, in sequence around the outer edge of the first guide wheel 401, the inner edge of the seventh guide wheel 407, the outer edge of the sixth guide wheel 406, and the lower edge of the eighth guide wheel 408. The second end of the cutting line 2 passes, from front to back, in sequence around the outer edge of the fifth guide wheel 405, the inner edge of the tenth guide wheel 410, the outer edge of the ninth guide wheel 409, and the lower edge of the eleventh guide wheel 411. This structure cleverly reverses the direction of the cutting line 2 by 180°, aligning the third cutting station 43 with the first cutting station 41 and the fourth cutting station 44 with the second cutting station 42, facilitating simultaneous operation of multiple cutting stations and further improving processing efficiency. Furthermore, the four cutting stations are formed by a single cutting line 2, making it easier to control the cutting force of each cutting station to be stable and uniform, thereby improving the cutting effect.

[0081] In this embodiment, the first guide wheel 401 is aligned front-to-back with the sixth guide wheel 406, and the second guide wheel 402 is aligned front-to-back with the eighth guide wheel 408. The fourth guide wheel 404 is aligned front-to-back with the eleventh guide wheel 411, and the fifth guide wheel 405 is aligned front-to-back with the ninth guide wheel 409. This structure ensures that the cutting lines 2 corresponding to the first cutting station 41, the second cutting station 42, the third cutting station 43, and the fourth cutting station 44 are of uniform length, resulting in consistent and stable cutting forces. Furthermore, the cutting lines 2 of the first cutting station 41 and the third cutting station 43 are aligned front-to-back, and the cutting lines 2 of the second cutting station 42 and the fourth cutting station 44 are aligned front-to-back. When cutting material, when the material corresponds to the same front-to-back position, the tension of the cutting line 2 is consistent, resulting in a consistent cutting effect. This improves the consistency of the material cutting effect while maintaining a high cutting effect.

[0082] The above-mentioned twelfth guide wheel 412 is provided on the vertical assembly plate 300, and the vertical assembly plate 300 is vertically arranged on the rear side of the second vertical plane 200 and the front side of the drum 3. The thirteenth guide wheel 413 is provided on the second vertical plane 200 and is located above the eighth guide wheel 408.

The above structure allows the cutting line 2 to be wound around the drum 3 without deviation. When viewed from the right side, when the drum 3 rotates forward, the lower side of the drum 3 is the cutting line release side, and the upper side of the drum 3 is the cutting line return side. When the drum 3 rotates backward, the upper side of the drum 3 is the cutting line release side, and the lower side of the drum 3 is the cutting line release side, thereby achieving stable reciprocating transmission of the cutting line 2.

[0084] The fifteenth guide wheel 415 and the sixteenth guide wheel 416 are positioning guide wheels for limiting the position of the inlet and outlet wires; the twelfth guide wheel 412 and the fourteenth guide wheel 414 are floating guide wheels for cooperating with the tension adjustment mechanism 7 to achieve tension adjustment; the eighth guide wheel 408 and the eleventh guide wheel 411 are turning guide wheels for guiding the direction of the cutting wire to make a 90-degree turn; the seventh guide wheel 407 and the tenth guide wheel 410 are steering guide wheels for guiding the cutting wire to change direction; the third guide wheel 403 is a tension wheel for cooperating with the tension control mechanism to achieve tension control; a cutting station is formed between the first guide wheel 401 and the second guide wheel 402 of the cutting wheel, and a cutting station is formed between the fourth guide wheel 404 and the fifth guide wheel 405.

[0085] In this embodiment, a roller moving mechanism 5 is provided for driving the roller 3 to move back and forth in the axial direction and the front-back direction. The roller moving mechanism 5 is provided on the frame 1. Figures 17-19As shown, the roller moving mechanism 5 of this embodiment includes a driving member 510 for driving the roller 3 to reciprocate in a vertical axial direction, and a driving member 520 for driving the roller 3 to reciprocate back and forth. The roller 3 is provided with a sensor capable of detecting the tension of the cutting wire 2 wound around the roller 3. Specifically, the frame 1 is provided with a first supporting plate 55. The frame 1 is provided with a screw rod 5100 extending vertically in the axial direction of the roller 3. The screw rod 5100 is connected to the output end of the driving member 510. The first supporting plate 55 is provided on the screw rod 5100 so as to be movable back and forth along the screw rod 5100 via a nut pair 5101. The roller 3 is provided on the first supporting plate 55, so that the roller 3 can achieve vertical axial reciprocating movement.

[0086] In this embodiment, the frame 1 is also provided with a guide rail 5102 arranged with parallel screws 5100. Correspondingly, a slide groove 551 is provided at the bottom of the support plate 55 to cooperate with the guide rail 5102. This structure is conducive to improving the stability of the vertical axial reciprocating movement of the roller. A second support plate 56 that can move back and forth along the axial direction of the roller 3 is provided above the first support plate 55. The roller 3 is provided on the second support plate 56. This structure allows the roller 3 to move back and forth along the axial direction. Since the position of the cutting line 2 extending and returning does not change during the process of the roller 3 retracting and releasing the line, in order to avoid interference between the cutting lines 2, the cutting line 2 is spirally wound along the axial direction of the roller 3 without overlapping. With the above structure, the position of the roller 3 can be changed to adapt to the winding requirements of the cutting line 2, thereby avoiding interference between the cutting lines 2 and improving the retraction and release stability of the cutting line 2. The upper wall of the first support plate 55 is provided with a screw rod 5200 that extends axially and can rotate along the roller 3. A driving member 520 is provided on one side of the first support plate 55 for driving the screw rod 5200 to rotate. The bottom of the second support plate 56 is mounted on the screw rod 5200 via a nut pair 5201, which can move back and forth along the screw rod 5200. This structure facilitates the axial reciprocating movement of the roller. The upper wall of the first support plate 55 is also provided with a guide rail 5202 arranged parallel to the screw rod 5200. Correspondingly, the bottom of the second support plate 56 has a chute 561 that cooperates with the guide rail 5202. This structure helps to improve the stability of the roller's axial reciprocating movement. For ease of assembly, the second support plate 56 is provided with vertically extending mounting plates 562 at each end. The roller 3 is located above the second support plate 56 and is rotatably constrained to the corresponding mounting plates 562 at both ends. The outer side of the mounting plates 562 is provided with a driving member 530, whose output end is connected to the roller 3.

[0087] In this embodiment, the driving members 510, 520, and 530 are all motors, and the sensors, driving members 510, 520, and 530 are all electrically connected to the same control system. The sensors in this embodiment can be provided separately or integrated with the output shaft of the driving member 530 to detect changes in the tension of the cutting line on the drum 3 through the output torque of the motor.

[0088] This embodiment can detect the tension of the cutting line 2 wound on the drum 3 in real time through the sensor. During the cutting process of the cutting line 2, the distance between the drum 3 and the cutting area can be changed by moving the drum 3 back and forth vertically, thereby changing the tightness and tension of the cutting line 2 and adjusting the tension of the cutting line 2 in real time.

[0089] like Figures 6-10 As shown, the tension control mechanism d of this embodiment includes a third guide wheel 403, a tension sensor 78, and a third elastic mechanism 730. The third elastic mechanism 730 is located below the third guide wheel 403 and ensures that the third guide wheel 403 always moves upward. The tension sensor 78 is located on the third elastic mechanism 730, with its upper end abutting against the third guide wheel 403. The tension adjustment mechanism 7 is connected to the guide wheel assembly 4 and is used to drive the twelfth guide wheel 412 and the fourteenth guide wheel 414 to float up and down as the tension of the cutting line 2 changes, thereby stabilizing the tension on the cutting line 2. The tension adjustment mechanism 7 includes a twelfth guide wheel 412, a fourteenth guide wheel 414, a first elastic mechanism 710, and a second elastic mechanism 720. The twelfth guide wheel 412 and the fourteenth guide wheel 414 are respectively arranged on the frame 1 so as to be movable up and down. The first elastic mechanism 710 is arranged below the twelfth guide wheel 412 and enables the twelfth guide wheel 412 to always maintain a tendency to move upward. The second elastic mechanism 720 is arranged below the fourteenth guide wheel 414 and enables the fourteenth guide wheel 414 to always maintain a tendency to move upward.

[0090] Specifically, a first prefabricated component 7100 is provided above the twelfth guide wheel 412, and is capable of cooperating with the first elastic mechanism 710 to set the up and down floating displacement of the twelfth guide wheel 412; a second prefabricated component 7200 is provided above the fourteenth guide wheel 414, and is capable of cooperating with the second elastic mechanism 720 to set the up and down floating displacement of the fourteenth guide wheel 414; a third prefabricated component 7300 is provided above the guide wheel 403, and is capable of cooperating with the third elastic mechanism 730 to set the up and down floating displacement of the guide wheel 403. Specifically, the first prefabricated component 7100 is fixed above the twelfth guide wheel 412 through the first assembly plate 7101, and the output end 7102 of the first prefabricated component 7100 passes through the first assembly plate 7101 and abuts against the rear portion of the twelfth guide wheel 412; the second prefabricated component 7200 is fixed above the fourteenth guide wheel 414 through the second assembly plate 7201, and the output end 202 of the second prefabricated component 7200 passes through the second assembly plate 7201 and abuts against the rear portion of the fourteenth guide wheel 414; the third prefabricated component 7300 is fixed above the guide wheel 403 through the third assembly plate 7301, and the power output end 7302 of the third prefabricated component 7300 extends downward from the third assembly plate 7301 and abuts against the rear portion of the guide wheel 403. The third assembly plate 7301 is also provided with a sensor 7303 that can detect whether the line is broken or not, and a limit screw 7304 that can abut against the guide wheel 403 in the broken state to protect the sensor 7303. The length of the power output end 7302 of the third prefabricated part 7300 extending downward from the third assembly plate 7301 is A, the length of the limit screw 7304 extending downward from the third assembly plate 7301 is B, and the length of the sensor 7303 extending downward from the third assembly plate 7301 is C, A>B>C.

[0091] The above-mentioned first pre-set component 7100 and second pre-set component 7200 can be used to set the limit position of the twelfth guide wheel 412 / the fourteenth guide wheel 414 rising, and preset a certain value of tension for the cutting line 2 through the first elastic mechanism 710 / the second elastic mechanism 720; the above-mentioned third pre-set component 7300 can be used to set the limit position of the guide wheel 403 rising, and preset a certain value of tension for the cutting line 2 through the third elastic mechanism 730; during the cutting process, when the cutting line 2 breaks, the pressure of the cutting line 2 on the guide wheel 403 disappears instantly, the guide wheel 403 floats quickly and contacts the limit screw 7304, at which time, the sensor 7303 transmits the received signal to the controller to stop the equipment operation as soon as possible.

[0092] The first elastic mechanism 710, the second elastic mechanism 720, and the third elastic mechanism 730 of this embodiment have the same structure. Figure 8 、 9As shown, they all include a main body 711, an elastic member 712 and an adjusting rod 713. The main body 711 is provided with a mounting hole 7111 which passes through the main body 711, and the elastic member 712 is arranged in the mounting hole 7111 so as to be movable up and down. The adjusting rod 713 is constrained at the lower end of the mounting hole 7111 of the main body 711 so as to be movable up and down, and the upper end of the adjusting rod 713 is abutted against the lower end of the elastic member 712, and the upper end of the elastic member 712 is exposed above the mounting hole 7111.

[0093] Specifically, the elastic member 712 of this embodiment includes a linear spring 7121 and a push rod 7122. The linear spring 7121 is concealed in the mounting hole 7111. The push rod 7122 is positioned above the linear spring 7121. The upper end of the linear spring 7121 abuts against the lower end of the push rod 7122, and the lower end of the linear spring 7121 abuts against the upper end of the adjustment rod 713. The upper end of the push rod 7122 is exposed above the mounting hole 7111. The push rod 7122 can transmit the preset tension of the linear spring 7121 upward. Compared to direct transmission by the linear spring 7121, the push rod 7122 can improve the stability of tension transmission. To facilitate assembly and adjustment, the upper portion of the adjustment rod 713 has external threads. Correspondingly, the inner wall surface of the lower end of the mounting hole 7111 has internal threads. The upper portion of the adjustment rod 713 is threadedly connected to the lower end of the mounting hole 7111. By rotating the adjusting rod 713 , a controllable tension can be set on the elastic member 712 to meet the tension adjustment requirements of the cutting line of the cutting machine.

[0094] In this embodiment, a tension sensor 78 is disposed between the third guide wheel 403 and the third elastic mechanism 730. This tension sensor 78 can slide up and down and is used to detect the tension of the cutting line 2 in real time. The lower end of the tension sensor 78 abuts the upper end of the push rod 7122, and the upper end of the tension sensor 78 abuts the lower portion of the guide wheel 403. This tension sensor 78 not only facilitates the setting of the preset tension of the cutting line 2 and the setting of the cutting tension of the cutting line 2 in conjunction with the third elastic mechanism 730 before the machine is operated, but also provides real-time feedback of the tension of the cutting line 2 to the controller during the cutting process, allowing the controller to control the movement of the roller 3 and thus achieve macroscopic control of the tension of the cutting line 2.

[0095] In this embodiment, the process of pre-setting the tension of the cutting wire 2 by using the first elastic mechanism 710, the second elastic mechanism 720, and the third elastic mechanism 730 is performed after the winding of the guide wheel assembly 4 is completed. After the winding is completed, the first elastic mechanism 710, the second elastic mechanism 720, and the third elastic mechanism 730 are not pre-set with tension, and the twelfth guide wheel 412, the fourteenth guide wheel 414, and the guide wheel 403 are in a falling state under the action of their own gravity; the output end of the first pre-set component 7100, the output end of the second pre-set component 7200, and the output end of the third pre-set component 7300 are respectively extended downward by a certain distance. The position of the lower end of each prefabricated component output end is the upper limit position of the corresponding twelfth guide wheel 412 / fourteenth guide wheel 414 / guide wheel 403 in the normal cutting state; at this time, there is a certain distance between the output end 7102 of the first prefabricated component 7100 and the twelfth guide wheel 412, between the output end 7202 of the second prefabricated component 7200 and the fourteenth guide wheel 414, and between the output end 7302 of the third prefabricated component 7300 and the guide wheel 403; rotate the adjusting rods at the lower ends of the first elastic mechanism 710, the second elastic mechanism 720, and the third elastic mechanism 730 713 compresses the elastic member 712 in the first elastic mechanism 710, the second elastic mechanism 720, and the third elastic mechanism 730. The top rod 7122 at the upper end of the elastic member 712 pushes the corresponding twelfth guide wheel 412 / the fourteenth guide wheel 414 / the guide wheel 403 to move upward to overcome its own gravity and counteract the output end of the corresponding first prefabricated member 7100 / the second prefabricated member 7200 / the third prefabricated member 7300. At this time, the first elastic mechanism 710, the second elastic mechanism 720, and the third elastic mechanism 730 preset a force f on the cutting line through elastic compression. This force f will pass The tension sensor 78 transmits the signal to the controller and displays it on the control screen; the cutting line 2 is tightened by the roller 3, and the cutting line 2 pulls the corresponding twelfth guide wheel 412 / fourteenth guide wheel 414 / guide wheel 403 downward. The signal of the tension F on the cutting line 2 is transmitted to the controller through the tension sensor 78 and displayed in real time on the control screen until the value of the tension F on the cutting line 2 meets the requirement, and the output end 7102 of the first prefabricated component 7100, the output end 7202 of the second prefabricated component 7200, and the output end 7302 of the third prefabricated component 7300 move upward and leave the preset position.

[0096] The first elastic mechanism 710, the second elastic mechanism 720, and the third elastic mechanism 730 can all be pneumatic cylinders, with the power output end of each cylinder abutting against the bottom of the corresponding wheel. This is sufficient as long as the power output end of the cylinder can consistently provide the corresponding wheel with upward force. Compared to the aforementioned elastic structure, pneumatic cylinders offer greater controllability and can more accurately control tension balance.

[0097] The winding mechanism 6 of this embodiment is arranged at the rear side of the frame 1, and is used to wind the cutting line 2 onto the drum 3 or to recycle the waste line on the drum 3. Figures 11-16As shown, the winding mechanism 6 of this embodiment comprises a bobbin 63, a bracket 64, an oscillating member 65, and a floating guide wheel 66. The bobbin 63 is rotatably mounted on the rear side wall of the frame 1, positioned below and to the side of the drum 3. The bracket 64 is located on the rear side of the frame 1, above the bobbin 63, with its upper end positioned above the drum 3. The oscillating member 65 is mounted on the bracket 64, capable of reciprocating perpendicularly to the axis of the drum 3. The oscillating member 65 is mounted on the front side of the bracket 64. A rotating shaft 641 extending forward and backward is provided on the bracket 64. A shaft hole 650 extending forward is defined in the rear wall of the oscillating member 65, into which the front portion of the shaft is inserted. The inner wall of the shaft hole 650 rotatably engages the shaft 641 via a bearing 6100. A cover 6501 is also provided on the rear side of the shaft hole 650, which seals the bearing 6100 within the shaft hole 650, enabling the oscillating member 65 to oscillate back and forth. The floating guide wheel 66 is rotatably provided on the swinging body 65 and swings synchronously with the swinging body 65 . The axis of the floating guide wheel 66 is parallel to the axial direction of the drum 3 .

[0098] In this embodiment, a floating guide wheel 66 is mounted on the swinging body 65 via a support arm assembly 67. The upper portion of the support arm assembly 67 is vertically adjustable on the swinging body 65, while the lower portion of the support arm assembly 67 extends toward the drum 3. The floating guide wheel 66 is rotatably mounted on the lower portion of the support arm assembly 67. The floating guide wheel 66 is typically made of a plastic material. After a period of use, friction with the cutting line 2 can easily cause the guide groove 61 in the floating guide wheel 66 to deepen, causing the cutting line 2 to lose alignment with the centerline of the swinging body 65, affecting winding accuracy. With the above-described structure, the support arm assembly 67 is vertically movably mounted on the bracket 64. The height of the floating guide wheel 66 can be adjusted in real time as the depth of the guide groove 61 in the floating guide wheel 66 changes, thereby ensuring that the cutting line 2 is always aligned with the centerline of the swinging body 65, maintaining winding accuracy.

[0099] like Figure 13-15As shown, the support arm assembly 67 comprises a connecting arm 671 and a top plate 672. The connecting arm 671 is L-shaped, with a vertical portion 6711 constrained to the swinging body 65. The horizontal portion 6712 of the L-shaped connecting arm 671 extends toward the drum 3 and is used to mount the floating guide wheel 66. The top plate 672 is vertically adjustable above the swinging body 65 and is connected to the side of the connecting arm 671. An adjustment assembly 68 is connected between the top plate 672 and the swinging body 65, enabling the top plate 672 to be raised and lowered. The adjustment assembly 68 is threadedly connected between the top plate 672 and the swinging body 65. Two connecting arms 671 are arranged parallel to each other on either side of the swinging body 65. The connecting arms 671 are fastened to the side walls of the swinging body 65 via screws 6200. The floating guide wheel 66 is rotatably connected between the lower ends of the two connecting arms 671. The floating guide wheel 66 is rotatably connected between the two connecting arms 671 via a guide wheel shaft and corresponding bearings. This rotatable connection structure is a conventional rotating wheel mounting structure and will not be described in detail here. After the floating guide wheel 66 is installed, the cutting line 2 extends from the spool 63, passes around the upper edge of the floating guide wheel 66, and winds around the upper edge of the drum 3. The cutting line 2 at the top edge of the floating guide wheel 66 and the swing axis of the swing body 65 are approximately aligned. The cutting line 2 at the top edge of the floating guide wheel 66, the swing axis of the swing body 65, and the upper edge of the drum 3 are all in the same plane.

[0100] Specifically, such as Figure 15As shown, the adjustment assembly 68 includes an elastic member 681, an adjustment screw 682, and a positioning screw 683. The elastic member 681 is positioned between the top of the swinging body 65 and the top plate 672, ensuring that the top plate 672 maintains an upward movement. The top plate 672 has a through-hole 6721 extending vertically therethrough. Correspondingly, a threaded hole 651 is formed on the top wall of the swinging body 65. The adjustment screw 682 passes through the through-hole 6721 and its lower end is threadedly engaged with the threaded hole 651. The upper portion of the adjustment screw 682 has a circumferentially arranged retaining ring 6821 that abuts against the upper wall of the top plate 672. Turning the adjustment screw 682 allows for fine-tuning of the vertical position of the floating guide wheel 66 to meet the required height of the floating guide wheel 66, and this is easy to operate. The elastic member 681 comprises a spring 6811 and a push rod 6. A slot 652 is defined on the top wall of the swinging member 65 to accommodate the spring 6811. The spring 6811 is positioned within the slot 652, with its lower end abutting against the inner bottom wall of the slot 652. The lower end of the push rod 6 is connected to the upper end of the spring 6811 and concealed within the slot 652. The upper end of the push rod 6 abuts against the lower wall of the top plate 672, thereby maintaining an upward movement of the top plate 672 relative to the swinging member 65. Four sets of elastic members 681 are arranged around the periphery of the adjusting screw 682. The adjusting screw 682 extends vertically through the adjusting screw 682. A set screw 683 passes through the adjusting screw 682 and its lower end is threadedly connected to the bottom wall of the threaded hole 651. The upper end of the set screw 683 protrudes above the adjusting screw 682 and includes a stopper 6831 that abuts against the top wall of the adjusting screw 682, thereby limiting its upward movement. The length of the positioning screw 683 is greater than that of the adjusting screw 682. When assembled, the positioning screw 683 has an adjustment range 6832 located above the adjusting screw 682 and allowing the adjusting screw 682 to move upward. The positioning screw 683 prevents the top plate 672 from separating from the swinging member 65 when the adjusting screw 682 is over-adjusted, thereby improving assembly stability.

[0101] The bobbin 63 of this embodiment is mounted on the rear side wall of the frame 1 so that it can move back and forth axially along the drum 3. The frame 1 is also provided with a fourth drive member 620, which is a motor, that can drive the bobbin 63 to rotate in a set direction when the cutting line is being recycled. After the cutting line 2 has been used for a period of time, its performance deteriorates and there is a risk of breakage. Therefore, it needs to be replaced regularly. The above structure facilitates the recycling of waste line. The bobbin 63 is mounted on the frame 1 so that it can move back and forth via an assembly rack 69. The assembly rack 69 is connected to the frame 1 at its front and rear ends by transversely arranged guide rails 691. The upper portion of the assembly rack 69 has a horizontally arranged support plate 692. A bracket 64 is mounted on the support plate 692 and extends vertically through the lower portion. The support plate 692 and the upper portion of the bracket 64 have openings 6921 and 643 for the cutting line 2 to pass through, corresponding to the floating guide wheel 66. The above structure guides the cutting line 2 and prevents it from becoming disorganized.

[0102] When the cutting wire 2 on the bobbin 63 is wound onto the drum 3 using the winding structure of this embodiment, the bobbin 63 rolls, the drum 3 rotates and continuously moves axially, and the diamond wire on the bobbin continuously changes its position along the winding direction when the wire is discharged. After the diamond wire passes through the floating guide wheel 66, the floating guide wheel 66 swings back and forth perpendicular to the axial direction of the drum under the traction of the position change of the diamond wire, thereby balancing the tension change of the diamond wire caused by the different discharge positions on the bobbin. Since the diamond wire at the top edge of the floating guide wheel 66 is always colinear with the swing center line of the swing body during the swinging process of the guide wheel, it can ensure that the position of the diamond wire after passing the floating guide wheel 66 is constant, so that the bobbin can track the discharge position on the drum in real time while remaining motionless.

[0103] The workbench 8 of this embodiment can be moved forward and backward, up and down on the frame 1 and arranged corresponding to the cutting area to meet the cutting requirements. Figure 20 、 21 As shown, the workbench 8 includes a base 82, a first drive mechanism 83, an installation box 84, a lifting member 85, a second drive mechanism 86, and a workbench plate 87. The frame 1 has a horizontal mounting platform, and the base 82 is mounted on the mounting platform so that it can move back and forth. The first drive mechanism 83 is mounted on the frame 1 and is used to drive the base 82 to move back and forth. The lower end of the installation box 84 is fixed to the upper wall of the base 82. The installation box 84 is hollow inside to form a mounting cavity 841. The upper end of the installation box 84 has a mounting opening 8411 that communicates with the mounting cavity 841. The lifting member 85 is inserted into the mounting opening 8411 of the installation box 84 so that it can be raised and lowered, with its upper end always exposed above the mounting opening 8411. The second drive mechanism 86 is located in the mounting cavity 841 and is used to drive the lifting member 85 up and down. The workbench plate 87 is horizontally mounted on the upper end of the lifting member 85.

[0104] like Figure 20As shown, the second driving mechanism 86 of this embodiment includes a first screw rod 861, a first screw rod pair 862, a bearing 863, a second screw rod pair 864 and a first driving member 865. The edge of the mounting port 841 of the mounting box 84 is provided with a downwardly extending assembly cavity 8410, and the lifting member 85 is passed through from top to bottom to form a accommodating cavity 851. The first screw rod 861 can rotatably pass through the assembly cavity 8410 and the upper end extends into the accommodating cavity 851. The first screw rod pair 862 is matched with the first screw rod 861 and constrained on the lifting member 85.
