[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0039] See Figure 1 As shown, this embodiment provides a CNC sheet metal cutting equipment 100, including a frame 10, a non-powered roller material rack 20, a cutting device 50, a pressing device 40, and an automatic feeding device 30.

[0040] Reference Figure 1As shown, there is a pair of unpowered roller racks 20, which are arranged on the front and rear sides of the frame 10. That is, according to the conveying direction of the soft sheet 200, the pair of unpowered roller racks 20 are arranged on opposite sides of the frame 10. The unpowered roller racks 20 are used to provide support for the soft sheet 200 and enable the soft sheet 200 to be conveyed back and forth along the unpowered roller racks 20.

[0041] Reference Figure 1 and Figure 7 As shown, in this embodiment, the non-powered roller feeder 20 includes multiple rectangular feeders 21. The feeders 21 are arranged in the conveying direction of the soft sheet 200, and the multiple feeders 21 are evenly spaced laterally to provide support for the soft sheet 200 in the width direction. Each feeder 21 is equipped with multiple rollers 22. The center of the feeder 21 is hollow, and the multiple rollers 22 are spaced apart along the length direction of the feeder 21. The rollers 22 are installed inside the cavity, and their opposite ends are rotatably mounted on the inner wall of the feeder 21. When the soft sheet 200 is placed on the non-powered roller feeder 20 for conveying, the bottom surface of the soft sheet 200 contacts the roller 22, and the soft sheet 200 is transported by transmission on the roller 22 to reduce the frictional resistance during the movement of the soft sheet 200.

[0042] Reference Figure 1 As shown, in order to prevent the outer edges of the flexible sheet 200 from sagging due to lack of support during the conveying process, support plates 23 arranged along the conveying direction of the flexible sheet 200 are respectively installed on the outer edges of the non-powered roller rack 20. That is, the support plates 23 contact the outer edges of the flexible sheet 200 to provide upward support for the outer edges of the flexible sheet 200, thereby improving the phenomenon of the outer edges of the flexible sheet 200 sagging due to lack of support.

[0043] In this embodiment, the working panel and the material support plate 23 on the upper end face of the frame 10 are both made of smooth, friction-resistant and wear-resistant sheet material to avoid scratches on the bottom surface of the soft sheet material 200 during the conveying and moving process.

[0044] Reference Figure 1 , Figure 2 and Figure 8As shown, in this embodiment, the automatic feeding device 30 includes a drive motor 31, a connecting rod shaft 32, a pair of rolling components 34, a feeding rod support rod 33, and multiple sets of clamping and pressing cylinder assemblies 35. The pair of rolling components 34 are fixedly installed at opposite ends of the connecting rod shaft 32. The pair of rolling components 34 are respectively installed on opposite sides of the upper end face of the unpowered roller material rack 20. The drive motor 31 is fixedly connected to one end of the connecting rod shaft 32. The feeding rod support rod 33 is fixedly installed on the connecting rod shaft 32. The feeding rod support rod 33 can move back and forth along the unpowered roller material rack 20 through the rolling components 34. Multiple sets of clamping and pressing cylinder assemblies 35 are fixedly installed laterally at intervals on the feeding rod support rod. The clamping and pressing cylinder assemblies are used to clamp the soft board 200.

[0045] The power output by the drive motor 31 is synchronously transmitted to a pair of rolling components 34 through the connecting rod shaft 32. The pair of rolling components 34 can move back and forth synchronously along the unpowered roller rack 20. The rolling components 34 moving back and forth can synchronously drive the feeding rod support rod to move back and forth, thereby driving the clamping and pressing cylinder assembly installed on the feeding support rod to move back and forth. Thus, the clamping and pressing cylinder assembly can drive the soft sheet 200 to move back and forth along the unpowered roller rack 20.

[0046] The soft sheet 200 is clamped by multiple sets of clamping and pressing cylinder assemblies 35 in the automatic feeding device 30, and the sheet is pulled backward until it reaches the end of the unpowered roller material rack 20. After the soft sheet 200 is cut, the multiple sets of clamping and pressing cylinder assemblies 35 then drive the excess soft sheet 200 to gradually return to its original position. This achieves feeding and unloading on the same side, solving the problem of back-and-forth movement.

[0047] Reference Figure 2 and Figure 8 As shown, in this embodiment, the clamping and pressing cylinder assembly includes a clamping cylinder 352, a cylinder fixing seat 351, a clamping cylinder head 353, and a pad 354. The cylinder fixing seat 351 is fixedly installed on the feeding rod support rod. The clamping cylinder 352 is vertically fixedly installed on the cylinder fixing seat 351. The clamping cylinder head 353 is fixedly installed on the piston rod of the clamping cylinder 352. The clamping cylinder 352 is used to drive the clamping cylinder head 353 to move vertically up and down. The pad 354 is fixedly installed on the feeding rod support rod and is located directly below the clamping cylinder head 353.

[0048] When it is necessary to clamp the flexible sheet 200, the drive motor 31 drives the rolling assembly 34 to move, causing the clamping and pressing cylinder assembly to move along the unpowered roller rack 20 to the outer edge of one side of the flexible sheet 200. At this time, the clamping cylinder 352 drives the clamping cylinder head 353 to move downward, away from the pad 354 below, so that the clamping cylinder head 353 and the pad 354 have a certain vertical gap, so that the flexible sheet 200 can enter horizontally between the clamping cylinder head 353 and the pad 354. Within the gap formed by 54, as the drive motor 31 moves, the clamping and pressing cylinder assembly moves above one side edge of the soft sheet 200. The outer edge of one side of the soft sheet 200 is located within this gap. The clamping cylinder 352 drives the clamping cylinder head 353 to move vertically downward, pressing the outer edge of one side of the soft sheet 200 onto the pad 354. Subsequently, under the action of the drive motor 31, the clamping and pressing cylinder assembly drives the soft sheet 200 to move along with the gift support rod.

[0049] Reference Figure 2 and Figure 10 As shown, specifically in this embodiment, the rolling assembly 34 includes a first gear 342 and a first rack 341. The first gear 342 is fixedly installed at one end of the connecting rod shaft 32, and the first rack 341 is fixedly installed on the upper surface of the unpowered roller feeder 20 along the length direction of the unpowered roller feeder 20. The first gear 342 meshes with the first rack 341. Meanwhile, bearing seats are installed at opposite ends of the connecting rod shaft 32. The bottom ends of the bearing seats are slidably installed on the upper surface of the unpowered roller feeder 20, and the opposite ends of the feeding rod support rod are fixedly connected to the bearing seats respectively.

[0050] When the drive motor 31 operates, the power output by the drive motor 31 is transmitted to the connecting rod shaft 32, causing the connecting rod shaft 32 to rotate. The rotating connecting rod shaft 32 then drives the first gear 342, which is fixedly installed at both ends, to rotate. The rotating first gear 342 meshes with the first rack 341 below. Since the first rack 341 is fixed on the unpowered roller material rack 20, the first gear 342 will move along the length direction of the first rack 341. That is, the meshing of the first gear 342 and the first rack 341 will cause the bearing seat to move along the upper end face of the unpowered roller material rack 20. The moving bearing seat then drives the feeding rod support rod to move back and forth.

[0051] Reference Figure 3 and Figure 4 As shown, in this embodiment, the pressing device 40 is fixedly installed on the frame 10 and is located directly above the cutting device 50. The pressing device 40 is used to press the soft board 200 tightly against the upper end face of the non-powered roller material rack 20.

[0052] Specifically, the pressing device 40 includes a pressing rod 43, a pressure cylinder 42, and a gantry frame 41. The gantry frame 41 is fixedly installed on the upper end face of the frame 10, and the pressure cylinder 42 is fixedly installed on the gantry frame 41. The piston rod of the pressure cylinder 42 is fixedly connected to the pressing rod 43, and the pressing rod 43 is located directly above the cutting device 50. When it is necessary to cut the soft sheet 200, the pressure cylinder 42 drives the pressing rod 43 to move vertically downward, so that the pressing rod 43 presses the soft sheet 200 against the worktable of the frame 10. At this time, the automatic feeding device 30 stops moving, and the cutting device 50 performs a transverse cut on the soft sheet 200.

[0053] Reference Figure 1 , Figure 5 , Figure 6 and Figure 9 As shown, in this embodiment, the cutting device 50 is disposed at the bottom end of the frame 10, and the cutting device 50 is used to perform transverse cutting on the soft board 200. Specifically, the cutting device 50 includes a bottom guide rail seat 51, a second rack 53, a second gear 54, a bottom slide plate 52, a servo motor 55, a motor 59, and a saw blade 510. The bottom guide rail seat 51 is fixedly installed at the bottom end of the frame 10, the second rack 53 is fixedly installed on one side of the top end of the bottom guide rail seat, the servo motor 55 is connected to the second gear 54, the second gear 54 meshes with the second rack 53, the servo motor 55 is fixedly installed on the bottom slide plate 52, and the bottom end surface of the bottom slide plate 52 forms a sliding connection with the upper end surface of the bottom guide rail seat 51. For example, a slider is installed on the bottom end surface of the bottom slide plate 52, and a slide rail that slides and engages with the slider is installed on the upper end surface of the bottom guide rail seat 51. The motor 59 is fixedly mounted on the upper surface of the bottom slide plate 52. The motor 59 is fixedly connected to the saw blade 510. The upper surface of the frame 10 is provided with a cutting groove 11 for the saw blade 510 to rotate and cut. That is, the saw blade 510 moves laterally along the cutting groove 11 to cut the soft board 200. The bottom surface of the pressure rod 43 is provided with a slot 44 that cooperates with the saw blade 510 for cutting (see reference). Figure 4 (As shown).

[0054] Reference Figure 6 and Figure 9 As shown, in order not to affect the back-and-forth conveying of the soft board 200, the cutting device 50 also includes a lifting cylinder 58, a lifting guide rail seat 56, and a lifting slide plate 57. The lifting guide rail seat 56 is fixedly installed on the upper end face of the bottom slide plate 52, the lifting cylinder 58 is fixedly installed on the lifting guide rail seat 56, the piston rod of the lifting cylinder 58 is fixedly connected to the lifting slide plate 57, the lifting slide plate 57 and the lifting guide rail seat 56 form a vertical sliding connection, and the motor 59 is fixedly installed on the lifting slide plate 57.

[0055] When the soft sheet material 200 needs to be cut, the lifting cylinder 58 drives the lifting slide plate 57 to move vertically upward along the lifting guide rail 56, so that the lifting slide plate 57 drives the saw blade 510 to protrude vertically upward from the cutting groove 11 on the frame 10. After the saw blade 510 rises to its position, the motor 59 drives the saw blade 510 to rotate, and at the same time, the servo motor 55 drives the second gear 54 to move laterally along the second rack 53, so that the saw blade 510 cuts the soft sheet material 200 laterally. In addition, it can be understood that the lifting cylinder 58 can also adjust the cutting height of the saw blade 510, that is, by adjusting the height of the saw blade 510 rising to protrude from the cutting groove 11, it can adapt to the cutting of soft sheet materials 200 of different thicknesses.

[0056] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
