[0033] Example 1
[0034] This embodiment provides an anti-pinch saw, which includes a mounting frame. A cutting saw is mounted on the left side of the mounting frame, and the cutting saw is connected to a first driving device that moves the cutting saw left and right. A profile placement frame is mounted on the right side of the mounting frame. After the cutting saw moves to the right, its blade moves to the profile placement frame and cuts the profiles on the frame. The profile placement frame includes a fixed frame 3 located behind the saw blade and a movable frame 4 located in front of the saw blade. The movable frame 4 is mounted on the mounting frame and moves back and forth. A second driving device 5 is also provided between the movable frame 4 and the mounting frame to drive the movable frame 4 to move back and forth. A first profile fixing device is provided at the fixed frame 3, and a second profile fixing device is provided at the movable frame 4.
[0035] The aforementioned anti-pinch saw divides the profile placement frame into two parts: a movable frame 4 at the front of the saw and a fixed frame 3 at the rear. The profile is placed on the profile placement frame by a material conveying device or manually. The saw moves toward the profile under the drive of the first drive device and cuts the profile.
[0036] After sawing is completed, the moving frame 4 and the second profile fixing device move forward under the drive of the second drive device 5, which in turn drives the remaining material forward, thereby moving the remaining material away from the cutting saw, and thus facilitating the removal of the saw blade from the cutting saw.
[0037] It should be noted that the cutting saw can be smoothly withdrawn when it is only close to the profile on the fixing frame 3. When necessary, the first profile fixing device can also be loosened, the profile on the fixing frame 3 can be moved to another position, and then the cutting saw can be withdrawn.
[0038] Specifically, in this embodiment, the mounting frame includes a partition plate 2 separating the left and right sides. The right side of the partition plate 2 is the profile placement rack; the left side of the partition plate 2 is a cutting saw. The saw blade can extend to the profile placement rack to cut the profile. The first profile fixing device includes a fixing plate 6 extending to the right from the upper part of the partition plate 2. The fixing plate 6 is provided with a first telescopic device 7 extending downward towards the fixing frame 3. The telescopic end of the first telescopic device 7 is provided with a first pressing block 8. When the first pressing block 8 moves downward, it presses the profile located on the fixing frame 3. This arrangement, with the first telescopic device 7 extending downward at the upper part of the fixing frame 3, presses the profile down onto the fixing frame 3 when the first telescopic device 7 moves downward, thereby fixing the profile vertically and preventing it from jumping.
[0039] Specifically, in this embodiment, the profile also needs to be fixed left and right to prevent the profile from moving. To this end, the first profile fixing device includes a second telescopic device 9 fixed to the right side of the fixing frame 3. The telescopic end of the second telescopic device 9 extends to the left. The telescopic end of the second telescopic device 9 is provided with a second pressing block. When the second pressing block moves to the left, it presses the profile located behind the saw blade.
[0040] A fixing plate 10 is provided on the right side of the fixing frame 3 at the position corresponding to the second telescopic device 9. The profile is clamped by the fixing plate 10 and the second clamping block. It should be noted that when the partition plate 2 is provided on the mounting frame, the fixing plate 10 can be a part of the partition plate 2 or a structure fixedly connected to the partition plate 2.
[0041] Specifically, in this embodiment, a specific movement method for the movable frame 4 is also provided: the movable frame 4 includes a horizontal plate, the upper surface of which is used to place profiles, and the horizontal plate and the mounting frame are connected by guide rails arranged front and rear. The guide rails allow the horizontal plate to move back and forth, and the second driving device 5 of the movable frame 4 can be any existing technology, such as a telescopic motor, capable of driving the horizontal plate to move back and forth.
[0042] Specifically, in this embodiment, the second profile fixing device on the moving frame 4 needs to move together with the moving frame 4 and the profile after sawing is completed. Therefore, the second profile fixing device should be fixedly connected to the moving frame 4 or move synchronously. In this embodiment: the second profile fixing device includes a third telescopic device 11 located on the right side of the moving frame 4. The telescopic end of the third telescopic device 11 extends to the left, and a third clamping block is provided at the telescopic end of the third telescopic device 11. When the third clamping block moves to the left, it clamps the profile located in front of the saw blade.
[0043] The movable frame 4 has an upwardly extending movable backing plate 12 on the left side. The movable backing plate 12 moves back and forth with the movable frame 4, and the profile is clamped by the movable backing plate 12 and the third clamping block.
[0044] More specifically, in this embodiment, the mounting frame includes a partition plate 2 separating the left and right parts, and the right side of the partition plate 2 is the profile placement rack; to avoid interference between the movement of the partition plate 2 and the movable backing plate 12: the partition plate 2 is provided with a hollow hole at the corresponding position of the third telescopic device 11, and the movable backing plate 12 moves back and forth within the hollow hole.
[0045] More specifically, in this embodiment, for the fixed installation of the third telescopic device 11, the movable frame 4 includes a horizontal plate, on which an upwardly extending mounting plate 13 is detachably provided, and the third telescopic device 11 is fixed to the mounting plate 13. When the mounting plate 13 is installed by means of bolts or other disassembly methods, the modular installation of the third telescopic device 11 is facilitated.
[0046] Specifically, in this embodiment, the mounting frame includes a partition plate 2 separating the left and right sides, and the right side of the partition plate 2 is the profile placement rack; the partition plate 2 is provided with at least one strip hole 14, and the saw blade of the cutting saw extends out from the strip hole 14.
[0047] More specifically, in this embodiment, the setting precision of the strip hole 14 is required to be high. Simultaneously, to prevent damage to the saw blade when it collides with the structure surrounding the strip hole 14, the structure surrounding the strip hole 14 is preferably made of aluminum. Therefore, the partition plate 2 has a mounting hole at the point where the cutting saw exits, and a mounting plate 15 is provided on the mounting hole. This mounting plate 15 can be made of aluminum, and the strip hole 14 is located on the mounting plate 15. In this embodiment, the mounting plate 15 is fixed to the partition plate 2 by bolts.
[0048] More specifically, in order to collect the leftover material, the front of the mobile frame is provided with a leftover material collection hopper. The leftover material is driven to the leftover material collection hopper, and after the third telescopic device 11 releases the leftover material, the leftover material falls into the leftover material collection hopper under the action of gravity.
[0049] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model and should be protected by the present utility model.
