Description

Technical Field

[0001] The present application relates to the field of sawing machines, and in particular to a high-precision automated band sawing machine. Background Art

[0002] At present, a band saw machine winds a band saw blade around two wheels and transmits the band saw blade between the two wheels, so that the band saw blade moves relative to the workpiece to be cut, thereby cutting the workpiece to be cut.

[0003] In the related art, the band saw blade needs to be cooled in time when used. However, in the common solution, the way to cool the band saw blade is simply to pour coolant on the top of the band saw blade, which can easily lead to uneven contact between the coolant and the band saw blade, and ultimately lead to poor cooling effect of the band saw blade. When the saw blade cooling effect is poor, it is easy to cause the saw blade to have bad teeth, which greatly affects the processing accuracy.

[0004] Patent document CN202510083738.7 discloses using a guide wheel assembly to guide the band saw while spraying coolant on the guide wheel assembly for diversion, so that the band saw is cooled as it passes. Although the coolant can fully contact the saw blade through the guide wheel assembly, the amount of coolant sprayed on the guide wheel assembly is limited, and only a small part of the saw blade can be in contact with the coolant.

[0005] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects: The coolant is attached to the guide wheel assembly and then the guide wheel assembly makes the coolant contact with the saw blade. The amount of coolant contacting the saw blade is small, and the cooling effect is insufficient. The saw blade can only cool the part outside the workpiece to be cut, while the part inside the workpiece to be cut will have difficulty for the coolant to enter the incision of the workpiece to be cut, resulting in insufficient cooling effect of the saw blade inside the workpiece to be cut. Ultimately, the cooling effect of the saw blade is poor, and it is difficult to maintain the stable use of the saw blade for high-precision processing for a long time. Summary of the Invention

[0006] In order to improve the problem of poor cooling effect on the saw blade and difficulty in maintaining stable use of the saw blade for high-precision processing for a long time, the present application provides a high-precision automated band saw machine.

[0007] The high-precision automated band sawing machine provided by this application adopts the following technical solutions: A high-precision automated band saw machine, comprising: a machine base having an outwardly protruding protrusion, the protrusion having a material receiving groove; a saw blade arranged above the material receiving groove; the saw blade having a cutting section and a transmission section; a driving member for at least driving the saw blade to move up and down; the high-precision automated band saw machine also includes: a first liquid box having a first cooling chamber and a through groove connected to the first cooling chamber; a second liquid box having a second cooling chamber and a drainage groove connected to the second cooling chamber; a driving pump for at least adding coolant to the first cooling chamber and the second cooling chamber; wherein the first liquid box is located in the transmission section, the transmission section passes through the through groove so that part of the transmission section is located in the first cooling chamber; the second liquid box is located above the cutting section, and the drainage direction of the drainage groove intersects with the cutting section; the driving member is also used to drive the first liquid box to move with the saw blade and drive the second liquid box to move to abut against the outer wall of the workpiece to be cut; the through groove has a downwardly extending guide port.

[0008] By adopting the above technical solution and utilizing the setting of the first liquid box, the saw blade passes through the through groove, and the driving member adds coolant to the first cooling chamber of the first liquid box, thereby ensuring that the speed at which the driving member adds coolant to the first liquid box is greater than the speed at which the coolant is discharged outward from the through groove, it can be ensured that the saw blade is immersed in the coolant in the first liquid box, thereby better dissipating heat from the saw blade. Moreover, since the saw blade is immersed in the first liquid box, the waste chips produced by cutting and adhering to the saw blade will also be separated from the saw blade due to the saw blade being immersed in the coolant. In addition, the saw blade is in a transmission state, so the saw blade will move relative to the first liquid box, and the movement of the saw blade in the coolant can better separate the waste chips from the saw blade, thereby improving the heat dissipation effect of the saw blade and also having the effect of cleaning the saw blade, thereby better ensuring the service life of the saw blade.

[0009] By adopting the above-mentioned technical solution and providing the second liquid box, coolant can be discharged onto the saw blade through the drainage groove above the saw blade, thereby cooling the cutting section of the saw blade. In addition, because the drainage groove matches the cutting section, when the saw blade cuts into the interior of the part to be cut, the drainage groove also discharges coolant into the incision of the part to be cut, thereby ensuring that a large amount of coolant can contact the saw blade entering or cutting into the part to be cut, thereby achieving a better cooling effect on the saw blade.

[0010] Among them, the guide port of the through groove is downward, so that the coolant can flow partially downward and outward in the through groove, so that it will flow partially downward on the saw blade, which can better separate the waste chips adhering to the saw blade downward from the saw blade.

[0011] Optionally, the first liquid box has an inlet and an outlet, and two inlets are provided; the liquid inlet direction of the inlet intersects with the transmission section; the driving pump injects the coolant into the first cooling chamber through the inlet; the outlet is arranged opposite to the inlet.

[0012] By adopting the above technical solution and utilizing the configuration of the inlet and outlet of the first liquid box, the coolant in the first liquid box is kept in a flowing state. Thus, the flowing coolant contacts the saw blade, allowing the flowing coolant to impact waste chips adhering to the saw blade, causing the waste chips to separate from the saw blade. Furthermore, the inlet's liquid inlet direction intersects the saw blade, so that when the coolant enters the first liquid box, the coolant directly impacts the saw blade, achieving a more effective cleaning effect on the saw blade and better separating waste chips from the saw blade.

[0013] Optionally, a lifting frame is provided on the machine base, the saw blade is provided on the lifting frame, and the driving member drives the lifting frame to rise to a first height position and descend to a second height position; a flow guide member is provided at the second liquid box, the flow guide member is flexible, and the flow guide member has a flow guide cavity and a plurality of flow guide holes connected to the flow guide cavity; one end of the flow guide member is connected to the second liquid box, and the other end of the flow guide member extends at least to the lifting frame; when the lifting frame is at the first height position, the flow guide member is suspended above the workpiece to be cut; when the lifting frame is at the second height position, the flow guide member is at least partially attached to the workpiece to be cut.

[0014] By adopting the above technical solution and utilizing the configuration of the flow guide, the coolant in the second liquid box can flow into the flow guide cavity of the flow guide and then be discharged outwardly through the flow guide hole, thereby spraying the coolant onto the workpiece to be cut or the saw blade over a large area and range. Furthermore, the flow guide is flexible, with one end of the flow guide communicating with the second liquid box and the other end extending to the lifting frame. Therefore, during the downward movement of the lifting frame, the flow guide will contact the workpiece to be cut. Due to the flexibility of the flow guide, the flow guide completely or largely adheres to the workpiece to be cut, thereby discharging the coolant directly and closely onto the workpiece to be cut, preventing the coolant from splashing onto the workpiece due to long-distance discharge. Consequently, the coolant can overflow the workpiece to be cut and flow into the incision of the workpiece to be cut, allowing more coolant to enter the incision and contact the band saw within the incision, thereby achieving a better cooling effect on the band saw. The guide piece is attached to the workpiece to be cut, and the coolant can overflow outward over a large area of ​​the workpiece to be cut, so that the coolant can better flow into the incision at most positions and contact the band saw, further improving the cooling effect of the band saw.

[0015] Optionally, the first liquid box is connected to the lifting frame; a flexible baffle is provided at the lower part of the first liquid box, and the flexible baffle has a converging surface located between the first liquid box and the material receiving trough; the converging surface has a recessed area and a protruding area, and the recessed area is located in the middle of the protruding area.

[0016] By adopting the above technical solution, since the band saw is in a moving state during cutting, the band saw will carry out some of the waste chips in the workpiece to be cut. The waste chips carried out by the band saw will also splash outward due to inertia. The provision of the flexible baffle can block the waste chips that splash outward, controlling the waste chips that splash outward within a certain range, thereby playing a role in preventing splashing. The flexible baffle is flexible and is between the first liquid box and the material receiving trough. Therefore, the lifting and lowering of the lifting frame causes the first liquid box to rise and fall synchronously, and the distance between the first liquid box and the material receiving trough changes. The flexible baffle adapts to the change in the distance between the first liquid box and the material receiving trough through its own flexible deformation.

[0017] By adopting the above-mentioned technical solution, the focusing surface on the flexible baffle is used to block the flying waste chips, while the recessed area and the protruding area on the focusing surface are used to concentrate the waste chips in the recessed area, and the protruding area prevents the waste chips from overflowing outward from the side of the flexible baffle, thereby better preventing the waste chips from flying over a large area.

[0018] Optionally, the flexible baffle includes: an elastic rope and a flexible membrane; the edge of the flexible membrane is curled to form an inserting cavity with two ends open; the surface of the flexible membrane forms the flow converging surface; two elastic ropes are provided; the elastic rope passes through the inserting cavity, one end of the elastic rope is fixed to the first liquid box, and the other end of the elastic rope is fixed to the material receiving trough, so that the flexible membrane extends between the first liquid box and the material receiving trough; the length of the flexible membrane matches the length of the elastic rope, and the width of the flexible membrane is greater than the distance between the two elastic ropes, so that the flow converging surface has the concave area and the convex area.

[0019] By adopting the above technical solution and the arrangement of the elastic cord, during the upward and downward movement of the lifting frame, the ends of the elastic cord are located at the first liquid box and the material receiving trough, respectively, so that the elastic cord can be placed in a straight line between the first liquid box and the material receiving trough. The flexible membrane is attached to the elastic cord, and a membrane opening is formed in the flexible membrane. This membrane opening is always located between the first liquid box and the material receiving trough, thereby better ensuring that waste is blocked and collected by the flexible membrane.

[0020] By adopting the above-mentioned technical solution, the flexible membrane forms a nested cavity that maintains a flat membrane opening. This prevents the flexible membrane from deforming during the upward and downward movement of the lifting frame, which could result in the flexible membrane being unable to receive or block waste. Furthermore, the flexible membrane's width is greater than the distance between the two elastic cords, causing the flexible membrane to be recessed relative to the elastic cords, thereby more easily accommodating waste and preventing it from spilling out.

[0021] Optionally, the high-precision automated band saw machine further includes a guide roller, which is arranged at the junction of the cutting section and the transmission section; the axial direction of the guide roller is parallel to the side of the cutting section; and the guide roller is partially or completely arranged in the first liquid box.

[0022] By adopting the above technical solution, the guide roller is used to form the saw blade into the cutting section, while the first fluid chamber is located in the transmission section. The saw blade is twisted and deformed at the junction of the cutting and transmission sections. Therefore, by placing the guide roller partially or entirely within the first fluid chamber, all areas where the saw blade is twisted and deformed are located within the first fluid chamber. This creates a stronger impact between the twisted and deformed areas of the saw blade and the coolant, effectively separating waste chips from the saw blade.

[0023] Optionally, the liquid inlet direction of the inlet is completely or partially opposite to the conveying direction of the saw blade.

[0024] By adopting the above technical solution, when the liquid inlet direction is completely or partially opposite to the conveying direction of the saw blade, the flowing coolant will offset the transmission direction of the saw blade, thereby better separating the waste chips adhering to the saw blade from the saw blade.

[0025] Optionally, an air injection pipe is provided in the first liquid box, and the air injection direction of the air injection pipe intersects with the saw blade; the air injection pipe is externally connected to an air compressor so that air is injected into the air injection pipe in a compressed state; and a plurality of air injection holes matching the air injection direction are opened on the side of the air injection pipe.

[0026] By adopting the above technical solution, air is compressed and then injected into the first liquid box. As a result, the compressed air rapidly expands when it reaches the coolant in the first liquid box, causing bubbles to burst and the coolant to churn rapidly. This increases the impact of the coolant on the saw blade when it comes into contact with the saw blade, thereby better separating waste from the saw blade. The air injection holes are provided on the side of the air injection pipe, and there are multiple air injection holes. This allows the air injection pipe to inject the compressed air into the coolant in the first liquid box over a large area, allowing the compressed air to be quickly ejected to the position of the saw blade, so that when the air bursts, it bursts near the saw blade, further enhancing the effectiveness of cleaning waste from the saw blade.

[0027] Optionally, a branch pipeline is provided on the gas injection pipe; the pipe opening of the branch pipeline is located on the side of the first liquid box and the pipe opening of the branch pipeline is opposite to the saw blade.

[0028] Optionally, a filter membrane with filter holes is provided at the pipe mouth of the branch pipe.

[0029] In summary, this application includes at least one of the following beneficial technical effects: By setting the first liquid box, the saw blade can be immersed in the coolant of the first saw blade during the transmission process, so that the saw blade in the transmission can be fully cooled, and the saw blade can be kept stable for a long time for high-precision processing. The method of immersing the saw blade in the coolant can also remove the waste chips adhering to the saw blade so that the waste chips are separated from the saw blade, thereby better ensuring the service life of the saw blade; The guide port of the through groove is downward, so that the coolant can flow partially downward and outward in the through groove, so that the coolant can flow partially downward on the saw blade, which can better separate the waste chips adhering to the saw blade downward from the saw blade.

[0030] By setting the second liquid box, when the cutting section of the saw blade cuts the workpiece to be cut, the drainage groove of the second liquid box will discharge the coolant into the incision of the workpiece to be cut, so that the coolant can penetrate more and more easily into the incision of the workpiece to be cut, and the saw blade in the incision of the workpiece to be cut can be cooled and dissipated in time, thereby better ensuring the heat dissipation effect of the saw blade; By setting the guide piece, when the saw blade cuts the workpiece to be cut, the guide piece fits against the surface of the workpiece to be cut, and then the guide piece discharges the coolant onto the workpiece to be cut, and the coolant flows into the incision along the workpiece to be cut. Therefore, in the position of the incision that the drainage trough cannot directly discharge to, the coolant can be better entered into the discharge port through the setting of the guide piece, so that a larger amount of coolant can be discharged into the incision of the workpiece to be cut.

[0033] The following is combined with Figure 1-17 This application is described in further detail.

[0034] The embodiment of the present application discloses a high-precision automated band sawing machine.

[0035] Refer to the attached drawings Figure 1-5 A high-precision automated band sawing machine includes: a machine base 1, a saw blade 2, a driving member 3, a first liquid box 4, a second liquid box 5 and a driving pump 6.

[0036] The machine base 1 has an outwardly protruding portion 11, which has a material receiving trough 111. The workpiece to be cut is placed on the protruding portion 11, and the saw blade 2 is positioned above the material receiving trough 111. Therefore, when the saw blade 2 cuts the workpiece, the waste generated by the cutting will fall directly into the material receiving trough 111, making it easy to collect the waste. In addition, the saw blade 2 has a cutting section 21 and a transmission section 22. The sawing machine also has transmission wheels 31. The saw blade 2 is wound around two transmission wheels 31. The transmission wheels 31 are driven by a drive motor 32 to rotate, causing the saw blade 2 to be driven. The saw blade 2 also has a guide roller 33, which is located at the junction of the cutting section 21 and the transmission section. The guide roller 33 is used to position the teeth of the saw blade 2 vertically downward, thereby achieving cutting of the workpiece to be cut. The saw blade 2 between the two guide rollers 33 is the cutting section 21, and the remaining portion of the saw blade 2 is the transmission section 22. The driving member 3 at least drives the saw blade 2 to move up and down. When the driving member 3 drives the saw blade 2 to move down, the cutting section 21 moves down, so that the cutting section 21 cuts into the workpiece to be cut, thereby achieving cutting of the workpiece to be cut.

[0037] Refer to the attached drawings Figure 1-5, 8-9, the first liquid box 4 has a first cooling chamber and a through groove 41 connected to the first cooling chamber. The first liquid box 4 is connected to the output end of the driving member 3, so that the first liquid box 4 moves up and down synchronously with the saw blade 2. The through groove 41 is a groove body that passes through the first liquid box 4, so that the saw blade 2 can pass through the through groove 41, and the saw blade 2 will be immersed in the first liquid box 4 during the transportation process. The driving pump 6 is at least used to add coolant to the first cooling chamber. Therefore, the speed at which the coolant is added to the first cooling chamber is greater than the speed at which the coolant overflows outward from the through groove 41, so that the saw blade 2 can be immersed in the coolant in the first liquid box 4. The saw blade 2 is ensured to be immersed in the coolant in the first liquid box 4, thereby better dissipating the heat of the saw blade 2. Since the saw blade 2 is immersed in the first liquid box 4, the waste chips produced by cutting and adhering to the saw blade 2 will also be separated from the saw blade 2 due to the saw blade 2 being immersed in the coolant. In addition, the saw blade 2 is in a transmission state, so the saw blade 2 will move relative to the first liquid box 4. The movement of the saw blade 2 in the coolant can better separate the waste chips on the saw blade 2 from the saw blade 2, thereby improving the heat dissipation effect of the saw blade 2 and also having the effect of cleaning the saw blade 2. This better ensures the service life of the saw blade 2.

[0038] Refer to the attached drawings Figure 1-5 8-9. Specifically, the first liquid box 4 is located in the transmission section 22, which extends through the through-slot 41, so that a portion of the transmission section 22 is located within the first cooling chamber. This prevents the coolant from affecting the normal cutting of the cutting section 21. The driving member 3 is also used to drive the first liquid box 4 to move with the saw blade 2 and to drive the second liquid box 5 to abut the outer wall of the workpiece to be cut. The through-slot 41 has a downwardly extending guide port 411. The guide port 411 allows the coolant to flow downward, effectively flushing waste chips from the saw blade.

[0039] The second liquid box 5 has a second cooling chamber and a drainage trough connected to the second cooling chamber. The drainage trough is located at the lower end of the second liquid box 5. The driving pump 6 is used to add coolant to the second cooling chamber. The second liquid box 5 is located above the cutting section 21. The drainage direction of the drainage trough intersects with the cutting section 21. The matching of the drainage trough and the cutting section 21 means that when observed from top to bottom, the drainage direction of the drainage trough and the cutting section 21 partially overlap, so that the coolant discharged from the drainage trough can directly fall on the cutting section 21, and when the cutting section 21 cuts into the interior of the workpiece to be cut, some coolant also flows into the incision of the workpiece to be cut and immerses in the cutting section 21, thereby cooling and dissipating the heat of the cutting section 21 located in the incision. Keeping the coolant in contact with the saw blade 2 that enters or cuts into the part to be cut in large quantities can better cool the saw blade 2.

[0040] Refer to the attached drawings Figure 5Specifically, the axial direction of the guide roller 33 is parallel to the side of the cutting section 21; the guide roller 33 is partially or completely arranged in the first liquid box 4. Preferably, the guide roller 33 is completely arranged in the first liquid box 4. Since the guide roller 33 is used to form the cutting section 21 of the saw blade 2, and the first liquid box 4 is arranged in the transmission section 22, and the saw blade 2 is twisted and deformed at the junction of the cutting section 21 and the transmission section 22. Therefore, by partially or completely arranging the guide roller 33 in the first liquid box 4, all the positions where the saw blade 2 is twisted and deformed can be located in the first liquid box 4. As a result, the positions where the saw blade 2 is twisted and deformed will have a stronger impact with the coolant, so that the waste chips on the saw blade 2 can be better separated.

[0041] Refer to the attached drawings Figure 1-3 In some embodiments, a lifting frame 34 is provided on the machine base, the saw blade 2 is provided on the lifting frame 34, and the driving member 3 drives the lifting frame 34 to rise to a first height position and to descend to a second height position. The driving member 3 includes a guide column 35 and a first driving cylinder 36. Among them, the first driving cylinder 36 is provided on the machine base, and the first driving cylinder 36 directly drives the lifting frame 34 to rise and descend, and the guide column 35 is slidably connected to the lifting frame 34, so that the guide column 35 is used to guide the rise and fall of the lifting frame 34. In addition, the transmission wheel 31 and the drive motor 32 are both provided on the lifting frame. The guide roller 33 is also provided on the lifting frame 34 to realize the rise and fall of the saw blade 2, so that the saw blade 2 can feed the workpiece to be cut.

[0042] Refer to the attached drawings Figure 4 、 6-7, 15-16, a flow guide 7 is provided at the second liquid box 5. The flow guide 7 is flexible and has a flow guide cavity and multiple flow guide holes 71 connected to the flow guide cavity. The flow guide 7 utilizes a flexible tubular body, with the flow guide cavity being the lumen of the tubular body and the flow guide holes 71 being holes located on the sidewalls of the tubular body. One end of the flow guide 7 is connected to the second liquid box 5, and the other end of the flow guide 7 extends at least to the lifting frame 34. The flow guide 7 has one open end and the other closed end. The open end of the flow guide 7 is connected to the end of the second liquid box 5, while the closed end of the flow guide 7 is also connected to the lifting frame 34. Specifically, the guide member 7 is located in the middle of the second liquid box 5. That is, the guide member 7 and the drainage groove of the second liquid box 5 are coplanar. Consequently, the guide member 7, the drainage groove of the second liquid box 5, and the incision of the workpiece to be cut are coplanar. Therefore, the coolant discharged from the drainage groove and the coolant discharged from the guide holes 71 of the guide member 7 can all be discharged into the incision of the workpiece to be cut. When the lifting frame 34 is at the first height position, the guide member 7 is suspended above the workpiece to be cut. Due to the flexibility of the guide member 7, when the lifting frame 34 is at the second height position, the guide member 7 at least partially contacts the workpiece to be cut. Since the guide member 7, the drainage groove of the second liquid box 5, and the incision of the workpiece to be cut are coplanar, when the guide member 7 is in contact with the workpiece to be cut, it contacts the incision of the workpiece to be cut, and the guide holes 71 of the guide member 7 discharge directly into the incision. By utilizing the configuration of the flow guide 7, the coolant in the second liquid box 5 can flow into the flow guide channel of the flow guide 7 and then be discharged outwardly through the flow guide hole 71, thereby spraying the coolant onto the workpiece to be cut or onto the saw blade 2 over a large area and range. This allows the coolant to be more quickly injected into the incision and contact the saw blade 2 in the incision, thereby improving the cooling effect on the saw blade 2.

[0043] Refer to the attached drawings Figure 1-3 In some embodiments, a second driving cylinder 37 is provided above the second liquid box 5, and the second driving cylinder 37 is provided on the lifting frame 34. The second driving cylinder 37 is used to drive the second liquid box 5 to rise and fall relative to the lifting frame 34, so that the second liquid box 5 is against the incision of the workpiece to be cut during the rising and falling process of the lifting frame 34.

[0044] Refer to the attached drawings Figure 1-3, 12-14, 17, specifically, a vent box 52 is provided in the second liquid box 5, and an air groove 521 is provided at the lower end of the vent box 52. The vent box 52 is located in the drainage groove. A gap is formed between the vent box 52 and the inner wall of the drainage groove, and an elastic rubber membrane 53 is provided in the gap. The elastic rubber membrane 53 blocks the drainage groove, so that the middle of the drainage groove is an air outlet, and the edge of the air outlet is the elastic rubber membrane 53. The driving member 3 includes a coolant storage tank 38, an air pump 39, and an air pipe 391. The air pump 39 is connected to the vent box 52 via the air pipe 391. The driving pump 6 injects coolant from the coolant storage tank 38 into the second liquid box 5, so that the coolant in the second liquid box 5 gradually increases, causing the rubber to expand. After the rubber membrane 53 expands, it will abut against the outer wall of the workpiece to be cut. A through hole 531 is provided in the rubber membrane 53, and the through hole 531 is used to allow the coolant to pass out. After the coolant flows outward through the through hole 531, it reaches the location of the drain groove, allowing the coolant to flow into the incision of the workpiece to be cut. After the rubber membrane 53 expands and abuts the workpiece to be cut, a nearly sealed area is formed at the incision of the workpiece to be cut. After the coolant is discharged into this area, it can prevent the coolant from splashing or flowing into the workpiece outside the incision. This ensures that the coolant flows more concentratedly into the incision of the workpiece to be cut.

[0045] Because the rubber membrane 53 has a limited degree of deformation, it can only fit within a portion of the upper end of the workpiece to be cut, allowing coolant to be injected into the portion of the upper end of the cut to be cut. Therefore, the guide member 7 can deform and fit within the portion of the workpiece that the rubber membrane 53 cannot reach, allowing coolant to be injected into the majority of the cut to be cut. This improves the cooling effect of the coolant on the cut of the workpiece, that is, improves the cooling effect of the coolant on the workpiece to be cut and the saw blade 2, thereby ensuring better cutting results and extending the service life of the saw blade 2.

[0046] In some embodiments, an elastic bag is provided on the side of the second liquid box 5. The elastic bag is connected to the second liquid box 5. A limiting plate is also provided on the side of the second liquid box 5, and the limiting plate is located above the elastic bag. When the pump 6 is driven to inject coolant into the second liquid box 5, the coolant in the second liquid box 5 gradually increases, causing the coolant to flow into the elastic bag, causing the elastic bag to expand. After the elastic bag expands, it abuts the limiting plate, and the elastic bag cannot expand upward. Therefore, the elastic bag expands downward and presses the workpiece to be cut away from the incision position, thereby assisting in positioning the workpiece to be cut. The elastic bag is made of a membrane, so after the elastic bag contacts the workpiece to be cut, it can help cool the workpiece to be cut, better ensuring the stability of the cutting process of the workpiece to be cut.

[0047] The limiting plate can directly adopt a flat plate body, and can also adopt a plate body of a surrounding plate. When the surrounding plate is adopted, it is mainly to allow the elastic bag to expand downward only to contact the workpiece to be cut.

[0048] Refer to the attached drawings Figure 1-3 11. In some embodiments, the first liquid box 4 is connected to the lifting frame 34; a flexible baffle 8 is provided at the lower portion of the first liquid box 4, and the flexible baffle 8 has a flow-converging surface 81 located between the first liquid box 4 and the material receiving trough 111. The flow-converging surface 81 has a recessed area 82 and a protruding area 83, and the recessed area 82 is located in the middle of the protruding area 83. The flexible baffle 8 includes: an elastic rope 84 and a flexible membrane 85. The edge of the flexible membrane 85 is curled to form a sheathing cavity 851 with two open ends, and the surface of the flexible membrane 85 forms the flow-converging surface 81. Two elastic ropes 84 are provided; the elastic rope 84 passes through the sheathing cavity 851, one end of the elastic rope 84 is fixed to the first liquid box 4, and the other end of the elastic rope 84 is fixed to the material receiving trough 111, so that the flexible membrane 85 extends between the first liquid box 4 and the material receiving trough 111. The length of the flexible membrane 85 matches the length of the elastic cords 84, and the width of the flexible membrane 85 is greater than the distance between the two elastic cords 84, so that the flow converging surface 81 has a concave area 82 and a convex area 83. The concave area is formed by the bending of the flexible membrane 85. Because the maximum width of the flexible membrane 85 is greater than the distance between the two elastic cords 84, the flexible membrane 85 bends between the two elastic cords 84, forming the concave area 82. The convex area 83 is the portion of the flexible membrane 85 that curls up relative to the concave area 82, and this portion is the convex area 83.

[0049] By adopting the above technical solution, through the arrangement of the elastic cord 84, during the upward and downward movement of the lifting frame 34, the ends of the elastic cord 84 are respectively located at the first liquid box 4 and the material receiving trough 111, thereby allowing the elastic cord 84 to be placed in a straight line between the first liquid box 4 and the material receiving trough 111. The flexible membrane 85 is located on the elastic cord 84, so there is a membrane opening in the flexible membrane 85. This membrane opening is always blocked between the first liquid box 4 and the material receiving trough 111, thereby better ensuring that waste is blocked and stored by the flexible membrane 85. The insertion cavity 851 formed by the flexible membrane 85 maintains a flat membrane opening, thereby preventing the flexible membrane 85 from deforming during the upward and downward movement of the lifting frame 34, thereby preventing the flexible membrane 85 from being able to receive or block waste. The width of the flexible membrane 85 is greater than the distance between the two elastic cords 84, which causes the flexible membrane 85 to be recessed relative to the elastic cords 84, thereby more easily accommodating waste and preventing waste from overflowing. The flexible membrane 85 is a membrane body, and the flexible membrane 85 is made of a rubber material with high wear resistance. In some other solutions, a layer of flexible mesh made of metal material can also be provided on the flexible membrane 85 to further increase the quality of the flexible membrane 85 itself.

[0050] Referring to Figures 13 and 10 , in some embodiments, the first liquid box 4 has two inlets 42 and two outlets. The drive pump 6 adds coolant from the coolant storage tank 38 to the two inlets 42. The inlet 42's direction of flow intersects the transmission section 22, allowing the coolant to directly impact the transmission section 22, facilitating rapid heat dissipation and cleaning of the saw blade 2. The drive pump 6 injects coolant into the first cooling chamber through the two inlets 42. The outlets are positioned opposite the inlets 42, facilitating direct flow of the coolant from the inlets 42 into the outlets and out of the outlets. This facilitates rapid coolant injection and discharge into the first liquid box 4, ensuring a relatively low temperature within the first liquid box 4, and effectively cooling the saw blade 2. Furthermore, the coolant's fluidity and the opposing outlets and inlets 42 facilitate rapid coolant flow, effectively flushing debris from the saw blade 2.

[0051] Specifically, the liquid inlet direction of the inlet 42 is completely or partially opposite to the conveying direction of the saw blade 2. When the liquid inlet direction of the inlet 42 is completely or partially opposite to the conveying direction of the saw blade 2, the flowing coolant will counteract the transmission direction of the saw blade 2, thereby better separating the waste chips adhering to the saw blade 2 from the saw blade 2.

[0052] Refer to the attached drawings Figure 11 In a preferred embodiment, the direction of coolant inlet 42 is partially opposite to the direction of delivery of the saw blade 2. A connecting block 43 is provided in the first liquid box 4, which includes a cavity and an inlet 42. The connecting block 43 has a surface parallel to the saw blade 2, on which the inlet 42 is located. The inlet 42 is angled relative to the connecting block 43, so that the direction in which coolant enters the first liquid box 4 at the inlet 42 is partially opposite to the direction of delivery of the saw blade 2. Two connecting blocks 43 are provided, one on one side of the saw blade 2 and the other on the other side. This provides two inlets 42 in the first liquid box 4, allowing both sides of the saw blade 2 to be flushed simultaneously, improving the cleaning effect of waste chips on the saw blade 2.

[0053] Refer to the attached drawings Figure 1-3 In some embodiments, an air injection pipe 91 is provided in the first liquid box 4 , with the air injection direction of the air injection pipe 91 intersecting the saw blade 2 . The air injection pipe 91 is connected to an external air compressor 9 to inject compressed air into the air injection pipe 91 . The air injection pipe 91 has multiple air injection holes on its side that match the air injection direction. The air compressor 9 is mounted on a machine base, and the air injection pipe 91 is partially a hose that connects the air compressor 9 to the first liquid box 4 .

[0054] After the compressed air is injected into the first liquid box 4, the compressed air will rapidly expand when it reaches the coolant in the first liquid box 4, causing bubbles to burst and the coolant to churn rapidly in the coolant in the first liquid box 4. This will cause the coolant to have a greater impact on the saw blade 2 when it comes into contact with the saw blade 2, thereby better separating the waste chips on the saw blade 2. The air injection holes are provided on the side of the air injection pipe 91, and there are multiple air injection holes, so that the air injection pipe 91 can inject the compressed air into the coolant in the first liquid box 4 over a large area, so that the compressed air can be quickly sprayed to the position of the saw blade 2, so that when the air bursts, the air bursts near the saw blade 2, further enhancing the effect of cleaning the waste chips on the saw blade 2.

[0055] In some other embodiments, a branch line is provided on the air injection pipe; the opening of the branch line is located on the side of the first liquid box and opposite the saw blade. The branch line discharges air outward, blowing away waste debris from the saw blade, further improving the waste cleaning effect while the coolant cleans the waste debris from the saw blade. The opening of the branch line is provided with a filter membrane with pores, which prevents dust and waste from entering the branch line from the outside when the device is not in use.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
