Detailed implementation manners

[0030] In order to further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail with reference to the accompanying drawings.

[0031] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] As Figures 1 to 7 shown, a safety protection device for an automotive seat material cutting machine provided by an embodiment of the present invention includes a cutting machine base 1, a longitudinal moving arm 2, a transverse moving arm 3 and a cutter 4. The longitudinal moving arm 2 is slidably connected to the top of the cutting machine base 1, the transverse moving arm 3 is slidably connected to the top of the longitudinal moving arm 2, the cutter 4 is fixedly connected to the front side of the transverse moving arm 3, a cavity 5 is formed inside the transverse moving arm 3, rotating structures 6 are arranged on both the left and right sides inside the cavity 5, the front sides of the rotating structures 6 penetrate and extend out of the surface of the transverse moving arm 3, and a protective cover 7 is rotatably connected to one side where the rotating structure 6 extends out, and the protective cover 7 covers the cutter 4.

[0033] Reference Figure 4 and Figure 5 Figure 5 , the rotating structure 6 includes a placement rack 601, a motor 602, a driving gear 603, a driven gear 604, a rotating rod 605, a connecting block 606 and a mounting plate 607. The placement rack 601 is fixedly connected to the inner wall of the cavity 5, the motor 602 is fixedly connected to the top of the placement rack 601, the driving gear 603 is fixedly connected to the output end of the motor 602, the driven gear 604 is rotatably connected to the inner wall of the cavity 5, and is located above the driving gear 603 and meshed with the driving gear 603. The rotating rod 605 is fixedly connected to the front side of the driven gear 604, and the rotating rod 605 penetrates and extends out of the surface of the lateral moving arm 3. The connecting block 606 is fixedly connected to the extended surface of the rotating rod 605, and the mounting plate 607 is fixedly connected to the surfaces on the left and right sides of the connecting block 606 by bolts, and one side of the mounting plate 607 close to the protective cover 7 is fixedly connected to the surface of the protective cover 7 by bolts.

[0034] With the above solution: by setting the rotating structure 6, the protective cover 7 can be driven to rotate, so that the cutter 4 on the front side of the lateral moving arm 3 can be exposed, and thus the cutter 4 can be operated.

[0035] Reference Figure 2 Figure 2 , a gap is left on one side where the two protective covers 7 are close to each other, and the protective cover 7 is made of transparent acrylic board.

[0036] With the above solution: by using the protective cover 7 made of transparent acrylic board, it is convenient for the staff to observe the working condition of the cutter 4, avoiding problems during the cutting work, and leaving a certain gap can facilitate the flipping of the two protective covers 7.

[0037] Reference Figure 4 and Figure 6 Figure 6 , a lifting structure 8 is fixedly connected inside the cavity 5, and the lifting structure 8 is in contact with the bottom surface of the protective cover 7.

[0038] With the above solution: by setting the lifting structure 8, a stress point can be provided for the non-flipped protective cover 7, avoiding deformation of the rotating rod 605 after long-term stress, and improving the stability of the protective cover 7 to prevent it from shaking.

[0039] Reference Figure 6, the lifting structure 8 includes a placement plate 801, a first electric cylinder 802, a cross bar 803, two L-shaped rods 804, two optical rods 805 and two electromagnetic blocks 806. The placement plate 801 is fixedly connected to the inner wall of the cavity 5. The first electric cylinder 802 is fixedly connected to the top of the placement plate 801, and the output end of the first electric cylinder 802 penetrates and extends out of the bottom of the placement plate 801. The cross bar 803 is fixedly connected to the output end of the first electric cylinder 802. The two L-shaped rods 804 are respectively fixedly connected to the left and right sides of the bottom of the cross bar 803, and the L-shaped rod 804 penetrates and extends out of the surface of the transverse moving arm 3, and the top of the L-shaped rod 804 is in contact with the bottom of the protective cover 7. The two optical rods 805 are both fixedly connected to the inner wall of the cavity 5, and the side of the optical rod 805 close to the cross bar 803 penetrates and extends out of the surface of the cross bar 803. The two electromagnetic blocks 806 are respectively fixedly connected to the tops of the two optical rods 805, and the electromagnetic block 806 is magnetically connected to the cross bar 803.

[0040] With the above scheme: by setting the lifting structure 8, the L-shaped rod 804 can be lowered when the protective cover 7 needs to be flipped, so as to provide a flipping space for the protective cover 7, and the protective cover 7 can be limited by the L-shaped rod 804 when the protective cover 7 is not flipped.

[0041] Reference Figure 7 , telescopic structures 9 are fixedly connected to both the left and right sides of the transverse moving arm 3, and the telescopic structure 9 is in contact with the surface of the rotated protective cover 7.

[0042] With the above scheme: by setting the telescopic structure 9, the structure can be started after the protective cover 7 is flipped, and then a force application point can be provided for the flipped protective cover 7 to prevent the protective cover 7 from falling due to gravity.

[0043] Reference Figure 7 , the telescopic structure 9 includes a second electric cylinder 901, a limiting rod 902, an extension block 903, a moving plate 904 and two push rods 905. The second electric cylinder 901 is fixedly connected to the left side of the transverse moving arm 3. The limiting rod 902 is fixedly connected to the front side of the second electric cylinder 901. The extension block 903 is sleeved on the surface of the limiting rod 902 and is slidably connected thereto. The moving plate 904 is fixedly connected to the output end of the second electric cylinder 901. The two push rods 905 are respectively fixedly connected to the top and bottom of the moving plate 904, and the side of the push rod 905 close to the extension block 903 is fixedly connected to the top of the extension block 903.

[0044] With the above scheme: by setting the telescopic structure 9, the flipped protective cover 7 can be limited to prevent the protective cover 7 from moving after being flipped, so as to facilitate the user to operate the cutter 4.

[0045] Reference Figure 7, a limiting disk 10 is fixedly connected to the front side of the limiting rod 902, and two clamping blocks 11 are fixedly connected to one side of the extension block 903 close to the second electric cylinder 901. The two clamping blocks 11 are located at the top and bottom of the limiting rod 902, and the clamping blocks 11 are slidably connected to the surface of the limiting rod 902.

[0046] Adopting the above solution: By setting the limiting disk 10 and the clamping blocks 11, the moving extension block 903 can be restricted to prevent the extension block 903 from exceeding the stroke after moving, resulting in the extension block 903 detaching from the limiting rod 902. The working principle of the present invention:

[0047] When the cutter 4 needs to be operated, the first electric cylinder 802 can be started first. The first electric cylinder 802 drives the cross bar 803 and the two L-shaped rods 804 to descend along the optical rod 805. At this time, the motor 602 can be started. The motor 602 drives the driving gear 603 to rotate. When the driving gear 603 rotates, it drives the meshing-connected driven gear 604 to rotate, thereby driving the rotating rod 605 and the connecting block 606 to rotate. Then, the rotation of the connecting block 606 can drive the protective cover 7 to flip. After the protective cover 7 flips to the specified position and exposes the cutter 4, the second electric cylinder 901 can be started. The second electric cylinder 901 drives the moving plate 904 and the two push rods 905 to move towards the side close to the second electric cylinder 901. Then, the movement of the push rods 905 drives the extension block 903 to extend along the limiting rod 902. At this time, the flipped protective cover 7 can be supported by the extension block 903, thereby improving the stability of the protective cover 7.

[0048] In summary: The safety protection device for the automobile seat material cutting machine, through the combined use of the cutting machine base 1, the longitudinal moving arm 2, the transverse moving arm 3, the cutter 4, the cavity 5, the rotating structure 6, the placing rack 601, the motor 602, the driving gear 603, the driven gear 604, the rotating rod 605, the connecting block 606, the mounting plate 607, the protective cover 7, the lifting structure 8, the placing plate 801, the first electric cylinder 802, the cross bar 803, the L-shaped rod 804, the optical rod 805, the electromagnetic block 806, the telescopic structure 9, the second electric cylinder 901, the limiting rod 902, the extension block 903, the moving plate 904, the push rod 905, the limiting disk 10 and the clamping block 11, solves the problem that during the cutting process, the material may rebound or splash due to the too-fast tool, and without the protection of the protective cover, these splashes may directly hit the operator, causing serious physical injuries.
