For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] Example 1
[0030] This embodiment provides a semi-automatic plastic cutting device with a safety protection structure, such as Figure 1 As shown, the machine body 1 includes a cutting cavity 2 in the middle of the machine body 1, a slide rail 3 is fixedly installed on the side of the machine body 1 and located at the cutting cavity 2, a slide plate 4 is slidably connected to the top of the slide rail 3, and a bottom cutting mold 5 is fixedly installed on the top of the slide plate 4. The operator puts the plastic part on the bottom cutting mold 5 and pushes the plastic part into the cutting cavity 2 by pushing the slide plate 4.
[0031] like Figure 2 As shown, a cutting assembly 6 is provided inside the body 1 and located at the cutting chamber 2. The cutting assembly 6 includes an electric push rod 61, a buffer assembly, a protective cover 64, a cutting pressure plate 65 and a touch switch 66. The electric push rod 61 is fixedly installed inside the body 1 and located at the cutting chamber 2. A buffer assembly is provided at the bottom of the electric push rod 61. The buffer assembly includes a push plate 62 and a buffer telescopic rod 63. The top of the push plate 62 is fixedly connected to the electric push rod 61. The bottom of the buffer telescopic rod 63 is fixedly installed with a protective cover 64. The middle part of the protective cover 64 is rotatably connected to the cutting pressure plate 65 through a rotating shaft.
[0032] The bottom of the cutting plate 65 is provided with a groove that matches the shape of the plastic part, and the cutting plate 65 and the bottom cutting die 5 cut the plastic part. The electric push rod 61 is pushed downward to move the push plate 62, the buffer telescopic rod 63, the protective cover 64 and the cutting plate 65 downward, and the cutting plate 65 and the bottom cutting die 5 are used to cut the plastic part together. And because there is a human arm at the bottom of the protective cover 64, the protective cover 64 is forced to move upward to shrink the buffer telescopic rod 63 to prevent the protective cover 64 and the body 1 from clamping the human arm. At the same time, due to the existence of the buffer telescopic rod 63, the protective cover 64 first covers the bottom cutting die 5, and then the cutting plate 65 moves down to cut the plastic part with the bottom cutting die 5, which prevents plastic chips from splashing when the plastic part is cut.
[0033] like Figure 2 and 4 As shown, there is a gap between the top of the cutting platen 65 and the protective cover 64. Initially, the cutting platen 65 is in a horizontal state, and the bottom end of the touch switch 66 contacts the cutting platen 65. The touch switch 66 is fixedly installed on the top inner wall of the protective cover 64. The touch switch 66 is located directly above the cutting platen 65. Two cutting platens 65 are provided and symmetrically distributed on the top of the cutting platen 65. The two cutting platens 65 are respectively located on the left and right sides of the rotating shaft of the cutting platen 65. The touch switch 66 is electrically connected to the electric push rod 61.
[0034] When a person's arm is at the bottom of the cutting platen 65 , the forces on both sides of the rotating shaft of the cutting platen 65 are uneven, and the cutting platen 65 deflects. The deflection of the cutting platen 65 squeezes the touch switch 66 at the top thereof, and the touch switch 66 is pressed to stop the electric push rod 61 from extending.
[0035] In this embodiment, the electric push rod 61 is lowered to enable the cutting plate 65 and the bottom cutting mold 5 to cut the plastic parts. During the downward movement of the protective cover 64 and the cutting plate 65, the protective cover 64 is buffered by the buffer telescopic rod 63 to prevent the presence of human arms between the protective cover 64 and the machine body 1. When a human arm is between the cutting plate 65 and the bottom cutting mold 5, the forces on both sides of the rotating shaft of the cutting plate 65 are uneven, and the cutting plate 65 is deflected. The deflection of the cutting plate 65 squeezes the touch switch 66 on its top. The touch switch 66 is pressed to stop the extension of the electric push rod 61, thereby preventing the electric push rod 61 from further extending and causing damage to the human arm.
[0036] Example 2
[0037] Based on Example 1, this embodiment proposes a semi-automatic plastic cutting device with a safety protection structure, such as Figure 2 and 3 As shown, a support assembly 7 is provided in the middle of the protective cover 64, and the support assembly 7 includes a pressure column 71 and a horizontal plate 72. The top of the pressure column 71 is fixedly connected to the push plate 62, and the pressure column 71 passes through the protective cover 64. The bottom of the pressure column 71 is fixedly installed with the horizontal plate 72. The horizontal plate 72 is in a horizontal state, and the cutting plate 65 is located directly below the horizontal plate 72.
[0038] When the push plate 62 moves downward, the push plate 62 drives the pressure column 71 and the horizontal plate 72 to move downward, and the cutting plate 65 is supported by the horizontal plate 72 to keep the cutting plate 65 in a horizontal state so as to cut the plastic parts.
[0039] like Figure 4 As shown, a return spring 74 is fixedly installed on the top inner wall of the protective cover 64, and the bottom end of the return spring 74 is fixedly connected to the protective cover 64. A slide 75 is slidably connected to the top of the cutting plate 65, and a guide telescopic rod 73 is hinged on the top of the slide 75. The top of the guide telescopic rod 73 is fixedly connected to the protective cover 64.
[0040] The cutting plate 65 is kept level by the guide telescopic rod 73 and the return spring 74. When a person's arm is between the cutting plate 65 and the bottom cutting mold 5, the level of the cutting plate 65 changes. The slide 75 is used to prevent the cutting plate 65 from being affected by the guide telescopic rod 73 and getting stuck when it deflects.
[0041] In this embodiment, when the push plate 62 moves downward, the push plate 62 drives the pressure column 71 and the horizontal plate 72 to move downward, and the horizontal plate 72 is used to support the cutting plate 65 so that the cutting plate 65 remains in a horizontal state to facilitate cutting of plastic parts.
[0042] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
