Description

Technical Field

[0001] This invention belongs to the field of building materials processing technology, and in particular relates to a multi-pass sawing machine. Background Technology

[0002] When constructing a house, curved walls are often encountered, requiring the use of curved wall panels. Currently, curved wall panels are mainly made by grooving one side of a straight panel and then bending it into a curved shape. Grooving straight panels relies heavily on manual labor, involving measuring and drawing lines with a ruler and then using a cutting saw to cut the grooves. This process is labor-intensive and time-consuming, and the width and depth of the grooves are difficult to control, resulting in poor quality and low efficiency in the production of curved panels. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide a multi-pass sawing machine to solve at least one technical problem existing in the current production of curved wall panels.

[0004] In a first aspect, embodiments of the present invention provide a multi-pass sawing machine, comprising:

[0005] frame;

[0006] A conveying mechanism, mounted on the frame and passing through the frame, is used to transport the sheet metal.

[0007] A cutting saw, comprising multiple saw blades spaced apart along the transport direction of the sheet metal, is mounted on a frame above the conveying mechanism and is capable of cutting the sheet metal on the conveying mechanism by reciprocating in a horizontal direction perpendicular to the transport direction of the sheet metal and reciprocating in a vertical direction.

[0008] Furthermore, the conveying mechanism includes multiple active rollers distributed on the front and rear sides of the frame, which rotate at the same speed under the drive of the transmission mechanism.

[0009] Furthermore, the conveying mechanism also includes multiple auxiliary rollers, which are spaced apart within the frame and can rotate under the influence of the plate above them.

[0010] Furthermore, the upper surfaces of the multiple auxiliary rollers and the multiple active rollers are on the same plane.

[0011] Furthermore, the multi-pass sawing machine also includes a pressing mechanism, which is located above the conveying mechanism on both the front and rear sides of the frame, and can reciprocate in the vertical direction to press the sheet metal on the conveying mechanism.

[0012] Furthermore, the pressing mechanism includes a pressing roller and a first hydraulic cylinder, the first hydraulic cylinder being connected between the frame and the pressing roller.

[0013] Furthermore, the multi-pass sawing machine also includes a U-shaped pressure plate disposed within the frame. The opening of the U-shaped pressure plate faces the conveying mechanism and can reciprocate in the vertical direction. The U-shaped pressure plate has multiple saw grooves through which the multi-pass saw blades pass.

[0014] Furthermore, the U-shaped pressure plate is provided with second hydraulic cylinders at both ends, and the second hydraulic cylinders are connected to the frame.

[0015] Furthermore, the cutting saw also includes a cutting motor and a moving motor. The cutting motor is mounted on a platform and is connected to the multi-saw blade via a belt. The moving motor drives the platform to reciprocate in a horizontal direction perpendicular to the transport direction of the sheet metal via a chain.

[0016] Furthermore, the cutting saw also includes a third hydraulic cylinder;

[0017] One side of the platform is hinged to the top of the frame, and the other side is connected to one end of the third hydraulic cylinder, the other end of which is connected to the top of the frame.

[0018] The multi-pass sawing machine provided in this embodiment of the invention has a conveying mechanism mounted on a frame for transporting boards. The cutting saw includes multiple saw blades spaced apart along the transport direction of the boards. The cutting saw is mounted on the frame above the conveying mechanism and can cut the boards on the conveying mechanism by reciprocating in a horizontal direction perpendicular to the transport direction of the boards and reciprocating in a vertical direction. This allows for automatic cutting by replacing manual labor with mechanical methods, resulting in uniform and freely controllable groove width and depth, thus improving the manufacturing quality and efficiency of curved wall panels.

[0024] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings and embodiments, so as to fully understand how the present invention uses technical means to solve technical problems and achieve technical effects and to implement it accordingly.

[0025] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or system. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or system that includes said element. Specific Implementation

[0027] Please refer to Figure 1 This is a three-dimensional structural diagram of a multi-pass sawing machine provided in an embodiment of the present invention. The multi-pass sawing machine includes a frame 10, a conveying mechanism 20, and a cutting saw 30.

[0028] The conveying mechanism 20 is mounted on the frame 10 and passes through the frame 10 for transporting the plate 40; the cutting saw 30 includes multiple saw blades 310 arranged at intervals along the transport direction of the plate 40, and is mounted on the frame 10 above the conveying mechanism 20, and can cut the plate on the conveying mechanism 20 by reciprocating in the horizontal direction perpendicular to the transport direction of the plate 40 and reciprocating in the vertical direction.

[0029] Specifically, the frame 10 is a square metal frame, welded from iron or stainless steel profiles; the conveying mechanism 20 is a strip structure, with the plate 40 placed on top and transported horizontally. The conveying mechanism 20 is mounted on the frame 10 and extends across it, from one side of the cutting saw 30 to the other, to transport the plate 40 into the frame 10 for cutting by the cutting saw 30, and then transport the cut plate 40 out of the frame 10, thus completing the cutting of the plate 40; the multiple saw blades 310 are arranged at intervals along the transport direction of the plate 40 on the body of the cutting saw 30. The number of saw blades 310 is not strictly limited in this embodiment and depends mainly on the width of the frame 10, the length of the plate 40, and the spacing of the kerfs 410. The emphasis here is on having multiple saw blades 310, i.e., the number of saw blades 310 is not less than two, so that the plate can be cut at once. The saw blade 40 cuts at least two kerfs 410, thereby greatly improving the cutting efficiency of the plate 40. Furthermore, the multiple saw blades 310 are all mounted on the frame 10 above the conveying mechanism 20. Each saw blade 310 is driven by a motor to rotate coaxially, and another motor drives it to reciprocate in a horizontal direction perpendicular to the transport direction of the plate 40, thereby cutting the plate 40 to form multiple kerfs 410. The multiple saw blades 310 can be driven by a lifting mechanism... The multi-saw blade 310 moves back and forth vertically so that it can be inserted into the plate 40 to cut it when it is lowered, and after the cut is completed, the multi-saw blade 310 is raised to leave the plate 40, thereby completing one cut of the plate 40; after one cut is completed, the conveying mechanism 20 continues to convey the plate 40 forward a distance, and the multi-saw blade 310 repeats the above actions to complete the first cut of the plate 40. This cycle is repeated to complete the cutting of the entire plate 40.

[0030] It should be noted here that the board 40 is formed by bonding two outer layers and a middle filling layer together with glue or its own adhesive properties. The outer layers are metallic coating materials and soft material layers, including but not limited to color-coated steel plates, aluminum-magnesium-manganese plates, stainless steel plates, aluminum foil, galvanized iron sheets, kraft paper, etc.; the filling layer includes but is not limited to rock wool, glass wool, polyurethane core material, etc. When cutting the board 40, only one side of the outer layer and the middle filling layer needs to be cut, while the other side of the outer layer remains intact. This creates multiple grooves 410 on the board 40. During construction, bending inward along the side with the grooves 410 forms an arc-shaped board, such as... Figure 2As shown. In this embodiment of the invention, the depth of the multi-slit groove 410 is controlled by the lifting mechanism driving the multi-slit saw blade 310 to reciprocate along the vertical direction, so as to ensure that the galvanized iron sheet layer on the other side is not damaged, thereby improving the cutting quality of the plate 40.

[0031] In the multi-pass sawing machine provided in the embodiments of the present invention, the multi-pass saw blade 310 can cut the plate 40 on the conveying mechanism 20 by reciprocating in the horizontal direction perpendicular to the transport direction of the plate 40 and reciprocating in the vertical direction, thereby automatically cutting by replacing manual labor with machinery, so that the width and depth of the cut groove are uniform and freely controllable, thereby improving the manufacturing quality and efficiency of the curved wall panel.

[0032] Furthermore, please combine Figure 3 and Figure 4 In other preferred embodiments of the present invention, the conveying mechanism 20 includes multiple active rollers 210 distributed on the front and rear sides of the frame 10, and the multiple active rollers 210 rotate at the same speed under the drive of the transmission mechanism (not shown in the figure).

[0033] Specifically, the conveying mechanism 20 also includes crossbars 220 at both ends of the multiple active rollers 210. The crossbars 220 pass through the frame 10. The multiple active rollers 210 are arranged at intervals along the length of the crossbars 220, mainly on the front and rear sides of the frame 10. The multiple active rollers 210 rotate at the same speed relative to the crossbars 220 under the drive of the transmission mechanism. The transmission mechanism includes, but is not limited to, belt drive or chain drive. The two ends of the transmission mechanism are respectively connected to the multiple active rollers 210 and a stepper motor (not shown in the figure). The multiple active rollers 210 rotate at the same speed through the drive of the stepper motor, thereby driving the plate 40 above them to move. It should be noted that the same speed here means that the rotation speed and rotation direction of the multiple active rollers 210 are the same.

[0034] Furthermore, in other preferred embodiments of the present invention, the conveying mechanism 20 further includes multiple auxiliary rollers 230, which are spaced apart within the frame 10 and can rotate under the drive of the plate 40 above it.

[0035] Specifically, the multiple auxiliary rollers 230 are also connected between the two crossbars 220, but they are mainly distributed within the frame 10. They serve as auxiliary supports when the cutting saw 30 cuts the plate, ensuring the flatness of the plate 40 and thus improving the cutting quality. Therefore, they do not require power transmission, i.e., they are not connected to the transmission mechanism and motor. However, they can rotate relative to the crossbars 220 under the drive of the plate 40 above them, so that the plate 40 can pass through the frame 10 under the drive of the multiple active rollers 210.

[0036] In addition, in other preferred embodiments of the present invention, in order to ensure the flatness of the plate 40 during conveying and cutting, and to make the plate 40 have a more uniform slit groove 410 to improve the cutting quality of the plate 40, the upper surfaces of the multiple auxiliary rollers 230 and the multiple active rollers 210 are on the same plane, that is, the heights of the multiple auxiliary rollers 230 and the multiple active rollers 210 are consistent, thus ensuring that the plate 40 is conveyed and cut on a horizontal plane.

[0037] Furthermore, in other preferred embodiments of the present invention, the multi-pass sawing machine further includes a pressing mechanism 50, which is disposed above the conveying mechanism 20 on the front and rear sides of the frame 10, and is capable of reciprocating in the vertical direction to press the plate 40 on the conveying mechanism 20.

[0038] Specifically, the pressing mechanism 50 includes two parts, one at the front and one at the back, respectively located on the front and back sides of the frame 10. Specifically, it is located on the frame 10 above the conveying mechanism 20 on the front and back sides of the frame 10. The pressing mechanism can reciprocate in the vertical direction so that it falls and presses on the plate 40 when the cutting saw 30 cuts the plate 40, keeping the plate 40 stationary during cutting. This prevents the plate 40 from shifting its position due to the force exerted by the multi-saw blade 310 during cutting, which would affect the straightness of the kerf groove 410. As a result, the cutting quality of the plate 40 can be effectively improved.

[0039] Furthermore, in other preferred embodiments of the present invention, the pressing mechanism 50 includes a pressing roller 510 and a first hydraulic cylinder 520, wherein the first hydraulic cylinder 520 is connected between the frame 10 and the pressing roller 510.

[0040] Specifically, the pressing mechanism 50 further includes a connecting plate 530 arranged along the width direction of the plate 40 and a connecting rod 540 arranged along the length direction of the plate 40. Two pressing rollers 510 are arranged on both sides of the bottom of the connecting plate 530. One end of the connecting rod 540 is connected to the frame 10 above the conveying mechanism 20, and the other end is used to set the first hydraulic cylinder 520. The output end of the first hydraulic cylinder 520 is connected to the top of the connecting plate 530. The first hydraulic cylinder 520 can drive the connecting plate 530 and the pressing rollers 510 to reciprocate in the vertical direction to press the plate 40.

[0041] In addition, in other preferred embodiments of the present invention, the multi-pass sawing machine further includes a U-shaped pressure plate 60 disposed within the frame 10. The opening of the U-shaped pressure plate 60 faces the conveying mechanism 20 and can reciprocate in the vertical direction. The U-shaped pressure plate 60 has multiple saw grooves 610 through which the multi-pass saw blades 310 pass.

[0042] Specifically, the U-shaped pressure plate 60 is located within the frame 10, with its opening facing downwards and capable of reciprocating vertically under the drive of the lifting mechanism. When cutting the sheet material 40, the U-shaped pressure plate 60 descends, fixing the sheet material 40 onto the conveying mechanism 20 to prevent displacement, thus ensuring the straightness of the kerf groove 410 and effectively improving the cutting quality of the sheet material 40. Furthermore, to facilitate the multi-saw blades 310 passing through the U-shaped pressure plate 60 to cut the sheet material 40, multiple saw grooves 610 need to be opened in the U-shaped pressure plate 60 for the saw blades 310 to pass through. It should be noted that when cutting different sheets of material 40 with different kerf groove spacings, the spacing of the multi-saw blades 310 needs to be adjusted, and a U-shaped pressure plate 60 with a different kerf groove spacing needs to be used to match it.

[0043] Furthermore, in other preferred embodiments of the present invention, the two ends of the U-shaped pressure plate 60 are provided with second hydraulic cylinders 620, and the second hydraulic cylinders 620 are connected to the frame 10.

[0044] Specifically, the lifting mechanism that drives the U-shaped pressure plate 60 to reciprocate in the vertical direction is the second hydraulic cylinder 620. The second hydraulic cylinder 620 is connected to the frame 10, and its output end is connected to both ends of the U-shaped pressure plate 60. The second hydraulic cylinder 620 can drive the U-shaped pressure plate 60 to move downward, thereby pressing the plate 40 onto the multi-auxiliary rollers 230. This prevents the plate 40 from shifting position due to the force exerted by the multi-saw blade 310 during cutting, which would affect the straightness of the kerf groove 410. This effectively improves the cutting quality of the plate 40.

[0045] In other preferred embodiments of the present invention, the cutting saw 30 further includes a cutting motor 320 and a moving motor 330. The cutting motor 320 is mounted on a platform 340 and is connected to the multi-saw blade 310 via a belt. The moving motor 330 drives the platform 340 to reciprocate in a horizontal direction perpendicular to the transport direction of the plate 40 via a chain.

[0046] Here, the cutting motor 320 provides the rotational driving force for the multi-saw blade 310, while the moving motor 330 provides the corresponding power for the cutting saw 30 to reciprocate along the width direction of the plate 40. Specifically, a platform 340 is provided on the frame 10 to support the cutting motor 320, and the multi-saw blade 310 is located on the side of the platform 340. The multi-saw blade 310 has a common rotation axis, and the cutting motor 320 drives the rotation axis to rotate via a belt, thereby causing the multi-saw blade 310 to rotate coaxially. The moving motor 330 is fixed on the frame 10 and drives the platform 340 to reciprocate in a horizontal direction perpendicular to the transport direction of the plate 40 via a transmission chain, thereby allowing the multi-saw blade 310 to reciprocate in the width direction of the plate 40, so that the multi-saw blade 310 cuts the plate 40 along the width direction of the plate 40 under the drive of the cutting motor 320.

[0047] Furthermore, in other preferred embodiments of the present invention, the cutting saw 30 further includes a third hydraulic cylinder 350; one side of the platform 340 is hinged to the top of the frame 10, and the other side is connected to one end of the third hydraulic cylinder 350, the other end of the third hydraulic cylinder 350 being connected to the top of the frame 10.

[0048] Here, the third hydraulic cylinder 350 is the lifting mechanism of the multi-saw blade 310, which can drive the multi-saw blade 310 to move back and forth in the vertical direction, so that the multi-saw blade 310 can descend downwards to extend into the plate 40 to cut it, and rise upwards to disengage from the plate 40 when the cutting is completed.

[0049] Specifically, one side of the platform 340 is hinged to the frame 10, and the other side is provided with the third hydraulic cylinder 350. The top of the third hydraulic cylinder 350 is connected to the frame 10, and the bottom, i.e. the output end, of the third hydraulic cylinder 350 is connected to the other side of the platform 340. Thus, through the extension and contraction of the third hydraulic cylinder 350, the platform 340 can rotate relative to the frame 10 along the hinge point, thereby driving the multi-saw blade 310 on the platform 340 to reciprocate in the vertical direction, so that when cutting the plate 40, it descends and extends into the plate 40, and when the cutting is completed, it rises and disengages from the plate 40.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
