DETAILED DESCRIPTION

[0031] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0032] like Figures 1 to 5 As shown, in one embodiment of the present invention, an automatic cutting device for processing blinds, the automatic cutting device comprises a bracket 10, a support seat 17, a stamping mechanism and a segmenting mechanism;

[0033] The support seat 17 is installed on the bracket 10, and the support seat 17 is used to support the sheet material 2; one end of the support seat 17 is provided with a material unloading area; the support seat 17 is provided with a stamping mechanism and a segmenting mechanism in sequence along the conveying direction of the sheet material 2, and the stamping mechanism is installed on the connecting plate 6, and the two ends of the connecting plate 6 are respectively slidably connected with the lifting slide 20 through the side sliders, and the connecting plate 6 is used to drive the stamping mechanism to reciprocate in the direction of the support seat 17 to stamp the sheet material 2;

[0034] The segmentation mechanism is used to segment the sheet material 2 after stamping. The segmentation mechanism includes an auxiliary push component 8, a feedback component 9 and a segmentation component. The segmentation component and the feedback component 9 are respectively located at two ends of the unloading area. The segmentation component includes a protective cover 18 and a segmentation cutter 19. The protective cover 18 is located on one side of the support seat 17, and the segmentation cutter 19 is installed on the protective cover 18. The segmentation cutter 19 is used to segment the sheet material 2. The two ends of the protective cover 18 are also slidably connected to the lifting slide 20 provided on the bracket 10, and one side of the end of the protective cover 18 is also connected to the end of the lifting slide 20 through a reset spring 33; the end of the protective cover 18 away from the support seat 17 is spaced apart from the connecting plate 6;

[0035] The auxiliary push assembly 8 includes a pad 82, one end of which is connected to the feedback assembly 9, and the other end of which is arranged opposite to the gap between the connecting plate 6 and the protective cover 18, and both sides of the pad 82 are also slidably connected to the transverse sliding groove 21 on the bracket 10 through the auxiliary sliding block 81;

[0036] When the length of the sheet material 2 after punching reaches the segment length, the end of the sheet material 2 collides with the feedback component 9, and the feedback component 9 drives the pad 82 to move to the gap between the connecting plate 6 and the protective cover 18. When the connecting plate 6 moves toward the direction close to the support seat 17 to the punching height, the punching mechanism punches the sheet material 2, and the segment cutting knife 19 segments the punched sheet material 2.

[0037] Preferably, the auxiliary pushing assembly 8 further comprises a push plate 83 and a push plate sliding pin 84, one end of the push plate 83 is connected to the feedback assembly 9 via the push plate sliding pin 84, and the other end of the push plate 83 is provided with a pad 82;

[0038] The feedback assembly 9 includes a feedback plate 93 and a feedback slot 91. One end of the feedback plate 93 is arranged opposite to the sheet material 2 on the support seat 17, and the other end of the feedback plate 93 is provided with a feedback slot 91. The feedback slot 91 is sleeved on the outer periphery of the push plate slide pin 84 and is slidably hinged with the push plate slide pin 84. The side of the feedback plate 93 is also hinged to the bracket 10 through a torsion spring shaft 92, and the torsion spring shaft 92 is located between the support seat 17 and the feedback slot 91; when the sheet material 2 pushes the feedback plate 93 to swing to the segmented angle, the feedback plate 93 pushes the pad 82 to move to the interval between the connecting plate 6 and the protective cover 18.

[0039] Thus, the sheet 2 can be conveyed toward the unloading area until the length of the sheet 2 in the unloading area reaches the segment length. As the end of the sheet 2 pushes the feedback plate 93 to swing, the push plate slide pin 84 cooperates with the feedback slide slot 91 to push the connecting plate 6 to move toward the protective cover 18, so that the pad 82 moves to the gap between the connecting plate 6 and the protective cover 18. Thus, when the connecting plate 6 moves toward the direction close to the support seat 17 to the cutting height, the segment cutting knife 19 is driven to move toward the direction close to the support seat 17 and segment the sheet 2. Thus, when the length of the conveyed sheet 2 reaches the conveying length, the sheet 2 is automatically cut into segments.

[0040] In order to facilitate the unloading of the segmented sheets 2, preferably, a guide slope 22 is provided at one end of the support seat 17 close to the unloading area. Thus, the segmented sheets 2 can be collected in the unloading area under the guidance of the guide slope 22. In practical application, a collection box can be provided in the unloading area to collect the segmented sheets 2.

[0041] It is necessary to explain that when the pad 82 is located on one side of the interval between the connecting plate 6 and the protective cover 18, and the connecting plate 6 moves toward the direction close to the support seat 17 to the cutting height, the connecting plate 6 is always spaced apart from the protective cover 18 during the process of descending to drive the stamping mechanism to stamp, thereby avoiding the problem that when the length of the sheet 2 in the unloading area has not reached the segmented length, the connecting plate 6 pushes the protective cover 18 to descend, causing the segmented cutting knife 19 to cut the sheet 2.

[0042] In this embodiment, the punching mechanism includes an upper mold plate 35, a lower mold plate 37, an upper mold 39 and a lower mold 38, the upper mold 39 and the lower mold 38 are respectively arranged on both sides of the sheet 2, and the upper mold 39 and the lower mold 38 cooperate to punch the sheet 2; the upper mold 39 is installed on the upper mold plate 35, the lower mold 38 is installed on the lower mold plate 37, the lower mold plate 37 and the upper mold plate 35 are respectively connected to the bracket 10 in a sliding manner, the upper mold plate 35 is also connected to the connecting plate 6 through the connecting side plate 40, and the lower mold plate 37 and the upper mold plate 35 are driven to move synchronously in the opposite direction through the connecting member. The connecting member includes a bidirectional screw rod 36, the bidirectional screw rod 36 is rotatably connected to the bracket 10, and the threaded parts at both ends of the bidirectional screw rod 36 are respectively threadedly connected to the lower mold plate 37 and the upper mold plate 35, so that the lower mold 38 can be driven to rise under the action of the bidirectional screw rod 36 when the upper mold 39 is driven to descend by the connecting plate 6, so that the upper mold 39 can cooperate with the lower mold 38 to punch out the fins of the sheet 2.

[0043] like Figure 1 , Figure 2 and Figure 6As shown, in one embodiment of the present invention, the automatic cutting equipment also includes a fixed-length conveying mechanism located on the side of the protective cover 18 away from the unloading area, the fixed-length conveying mechanism is used to convey the sheet material 2 to the unloading area, the fixed-length conveying mechanism includes a conveying shaft 31 and a first conveying roller 11, the conveying shaft 31 is provided with two and is arranged on both sides of the support seat 17, the two conveying shafts 31 are intermittently rotated in opposite directions, each conveying shaft 31 is installed with a first conveying roller 11, the two first conveying rollers 11 are arranged at intervals, and the interval between the two first conveying rollers 11 is a conveying area for conveying the sheet material 2, and the two first conveying rollers 11 are in friction contact with the sheet material 2 respectively.

[0044] In this embodiment, gears 34 are respectively installed on the two conveying shafts 31, and the two gears 34 are meshed and connected, so that when the motor drives one of the conveying shafts 31 to rotate, the two conveying shafts 31 can be driven to rotate synchronously in opposite directions, thereby realizing the function of conveying the sheet material 2.

[0046] When the conveying shaft 31 rotates until the connecting slide pin 32 is located in the concave guide groove 51 , the connecting plate 6 moves toward the direction close to the supporting seat 17 to the cutting height.

[0047] In actual application, the connecting plate 6 can also be driven to intermittently reciprocate by a hydraulic cylinder.

[0048] In this embodiment, the conveying shaft 31 is driven to rotate intermittently by an intermittent driving mechanism, and the intermittent driving mechanism includes a driving disc 41, a driving slide pin 43, a driving plate 44 and a driving shaft 45.

The other end of the driving plate 44 is connected to the driving shaft 45, and the driving shaft 45 is rotatably connected to the bracket 10. The driving motor drives the driving shaft 45 to rotate, thereby driving the conveying shaft 31 to rotate intermittently.

[0049] Preferably, the segment length of the sheet material 2 is an integer multiple of the circumference of the first conveying roller 11 .

[0050] In this embodiment, as the conveying shaft 31 rotates, the connecting pin 32 is slidably connected to the concave guide groove 51 or the annular guide groove 52 respectively, so that when the conveying shaft 31 rotates until the connecting pin 32 is located in the concave guide groove 51, the connecting plate 6 moves toward the direction close to the support seat 17, and then when the pad 82 is located in the gap between the connecting plate 6 and the protective cover 18, and the connecting pin 32 slides from the annular guide groove 52 to the concave guide groove 51, the connecting plate 6 moves to the cutting height, thereby driving the segmented cutting knife 19 to segment the sheet 2.
