[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Please refer to Figures 1-8, an embodiment of the present invention is: a precise cutting device for high-quality copper electric heating wires, including a bottom plate 1, a conveying frame 2 is fixedly connected to the top of the bottom plate 1, an electric wire reel 3 is installed on the inner wall of the conveying frame 2, a U-shaped plate one 4 is fixedly connected to the top of the bottom plate 1, a U-shaped plate two 5 is fixedly connected to the top of the bottom plate 1, a cylinder 6 is fixedly connected to the top of the U-shaped plate two 5, a cutter 7 is fixedly connected to the output end of the cylinder 6, a wire transporting plate 8 is fixedly connected to the inner wall of the U-shaped plate one 4, a pressing plate 9 is fixedly connected to the inner wall of the cutter 7, a fixed frame one 10 is fixedly connected to the top of the U-shaped plate one 4, a sliding rod 11 is slidably connected to the inner wall of the fixed frame one 10 through a spring, a jitter mechanism 13 for improving the discharging effect is arranged on the top of the bottom plate 1, a pushing and spreading mechanism 14 for preventing the excessive accumulation of electric heating wires is arranged on the top of the bottom plate 1, and a rubber block 12 is fixedly connected to the bottom of the sliding rod 11; When cutting the electric heating wire, the electric heating wire is conveyed to the cutting area through the electric wire reel 3. When the electric heating wire is conveyed, it will be transported on the inner wall of the wire transporting plate 8, which can reduce the stress of the electric heating wire, so as to ensure that the electric heating wire will not bend and improve the cutting accuracy of the electric heating wire. When the electric heating wire is conveyed to the cutting area, the cylinder 6 is started to drive the cutter 7 to move downward, so as to generate a squeezing force on the electric heating wire, and then the electric heating wire can be cut off, and multiple electric heating wires can be cut off in batches, greatly improving the cutting efficiency of the electric heating wire; The bottom of the cutter 7 is in contact with the inner wall of the U-shaped plate one 4, and the cutter 7 is used to cut off the electric heating wire. The inner wall of the wire transporting plate 8 is in contact with the bottom of the rubber block 12, and the rubber block 12 is used to fix the electric heating wire; During the process of cutting the electric heating wire, the downward movement of the cutter 7 drives the pressing plate 9 to move downward. The downward movement of the pressing plate 9 will contact the sliding rod 11, and then push the sliding rod 11 to move downward and compress the spring. The downward movement of the sliding rod 11 drives the rubber block 12 to move downward, so as to softly limit the electric heating wire on the surface of the wire transporting plate 8, so as to ensure that the electric heating wire is in a horizontal state during cutting, and then ensure that the length of the electric heating wire is the same each time it is cut, greatly improving the cutting accuracy, avoiding the problem that the length of the cut electric heating wire is different due to the inclination and deviation of the electric heating wire during cutting, which affects the cutting quality. At the same time, when limiting the electric heating wire, the rubber block 12 itself will deform, so as to avoid the problem of abrasion on the surface of the electric heating wire.

[0017] Working principle: When cutting the heating wire, the heating wire is transported to the cutting area through the electric wire reel 3. When the heating wire is transported, it will be transported on the inner wall of the wire transporting plate 8, which can reduce the stress of the heating wire, ensure that the heating wire will not bend, and improve the cutting accuracy of the heating wire. When the heating wire is transported to the cutting area; during the process of cutting the heating wire, the sliding rod 11 moves downward to drive the rubber block 12 to move downward, so as to softly limit the heating wire on the surface of the wire transporting plate 8, ensure that the heating wire is in a horizontal state during cutting, and then ensure that the length of the heating wire is the same each time it is cut.

[0018] Please refer to Figures 1-8 , on the basis of the above embodiment, in another embodiment of the present invention, the jitter mechanism 13 includes a collection box 131, the collection box 131 is installed and connected to the top of the bottom plate 1, the right side of the U-shaped plate 1 4 is fixedly connected with a U-shaped frame 132, the right side of the cutting knife 7 is fixedly connected with an L-shaped rod 1 133, the inner wall of the U-shaped plate 1 4 is rotatably connected with a jitter plate 134, the inner wall of the U-shaped frame 132 is threadedly connected with a threaded rod 135, the circumferential surface of the threaded rod 135 is rotatably connected with a wire blocking plate 136, the inner wall of the wire blocking plate 136 is fixedly connected with a sliding rod 137, and the inner wall of the U-shaped plate 1 4 is fixedly connected with an L-shaped rod 2 138; When the cutting of the heating wire is completed, the cutting knife 7 moves upward to drive the L-shaped rod 1 133 to move upward, the L-shaped rod 1 133 moves upward to drive the jitter plate 134 to rotate upward. At the same time, when cutting the heating wire, the cutting knife 7 moves downward to drive the L-shaped rod 1 133 to move downward, and the L-shaped rod 1 133 moves downward to drive the jitter plate 134 to rotate downward. When the jitter plate 134 rotates downward, it will contact the right side of the L-shaped rod 2 138 and generate vibration, so as to shake off the cut heating wire on the surface of the jitter plate 134, and then quickly discharge the heating wire, improve the cutting efficiency of the heating wire, and avoid the heating wire accumulating on the surface of the jitter plate 134, affecting the subsequent cutting of the heating wire; The top of the jitter plate 134 is rotatably connected with the L-shaped rod 1 133, and the jitter plate 134 is used to shake off the heating wire. The inner wall of the U-shaped frame 132 is slidably connected with the circumferential surface of the sliding rod 137. A pressure sensor is arranged on the left side of the wire blocking plate 136, and the electric wire reel 3 is electrically connected with the pressure sensor. The L-shaped rod 2 138 is in contact with the bottom of the jitter plate 134, and the wire blocking plate 136 is electrically connected with the air cylinder 6; When it is necessary to adjust the cut length of the heating wire, the cut part of the heating wire will be on the left side of the wire blocking plate 136. At this time, the wire blocking plate 136 will be subjected to the impact force generated by the heating wire during transportation. At this time, the wire blocking plate 136 will conduct an electrical signal to the electric wire coil 3 to stop the transmission of the heating wire. At the same time, the air cylinder 6 will be started. When adjusting the length, the screw rod 135 is rotated through the knob. The rotation of the screw rod 135 will contact the slider inside the U-shaped frame 132 through the thread on the surface, so that the screw rod 135 moves to the right relative to the U-shaped frame 132. The rightward movement of the screw rod 135 drives the wire blocking plate 136, and the rightward movement of the wire blocking plate 136 drives the sliding rod 137 to move to the right, so that the contact distance between the heating wire and the wire blocking plate 136 can be changed. Furthermore, heating wires of different lengths can be cut according to different needs, and multiple functions can be realized by adjusting the cutting length, meeting the switching of heating wires of different lengths, and avoiding the idle waste of equipment.

[0019] Working principle: When the cutting of the heating wire is completed, the cutter 7 moves upward to drive the first L-shaped rod 133 to move upward. The upward movement of the first L-shaped rod 133 drives the shaking plate 134 to rotate upward. At the same time, when cutting the heating wire, the cut heating wire falling on the surface of the shaking plate 134 can be shaken off, so that the discharging of the heating wire can be accelerated, and the cutting efficiency of the heating wire can be improved. When it is necessary to adjust the cut length of the heating wire, the screw rod 135 moves to the right to drive the wire blocking plate 136, and the rightward movement of the wire blocking plate 136 drives the sliding rod 137 to move to the right, so that the contact distance between the heating wire and the wire blocking plate 136 can be changed. Furthermore, heating wires of different lengths can be cut according to different needs.

[0020] The pushing and spreading mechanism 14 includes a fixed rod 141. The fixed rod 141 is fixedly connected to the inner wall of the collecting box 131 through a spring. A sliding plate 142 is slidably connected to the circumferential surface of the fixed rod 141. A pushing plate 143 is fixedly connected to the rear part of the sliding plate 142. A chamfered plate 144 is fixedly connected to the top of the shaking plate 134. A roller 145 is rotatably connected to the inner wall of the chamfered plate 144. A limiting frame 146 is fixedly connected to the top of the bottom plate 1. A fixed column 147 is fixedly connected to the left side of the collecting box 131; When discharging the heating wire, the upward rotation of the shaking plate 134 drives the chamfered plate 144 to move upward. The upward movement of the chamfered plate 144 drives the roller 145 to move upward. During the movement of the roller 145, it will contact the sliding plate 142 and can push the sliding plate 142 to move to the right. The rightward movement of the sliding plate 142 drives the pushing plate 143 to move to the right. When the pushing plate 143 moves to the right, the accumulated heating wires will be pushed and spread, so that the heating wires can be more evenly distributed inside the collecting box 131. Furthermore, the space utilization rate inside the collecting box 131 can be improved, and the situation of space waste can be avoided; On the left side of the fixed column 147, there is a fixedly connected groove block 148. On the top of the limit frame 146, there is a fixedly connected second fixed frame 149. Inside the inner wall of the second fixed frame 149, there is a moving rod 1410 slidably connected through a spring. At the bottom of the moving rod 1410, there is an inclined strip 1411 fixedly connected. The surface of the collection box 131 is in contact with the inner wall of the limit frame 146, and the limit frame 146 is used to determine the position of the collection box 131. The bottom of the pushing plate 143 is in contact with the inner wall of the collection box 131. The left side of the sliding plate 142 is in contact with the circumferential surface of the roller 145, and during the operation of the roller 145, it will push the sliding plate 142 to move. The inner wall of the groove block 148 is in contact with the bottom of the inclined strip 1411; When the electric heating wires stored in the collection box 131 are taken away for processing and then put back, the collection box 131 will come into contact with the inner wall of the limit frame 146, so as to ensure that the position where the collection box 131 is placed is the same as the original position. During the process of placing the collection box 131, the collection box 131 will drive the fixed column 147 to move. The movement of the fixed column 147 drives the groove block 148 to move. During the movement of the groove block 148, it will generate an upward extrusion force on the inclined strip 1411, causing the inclined strip 1411 to move upward. The upward movement of the inclined strip 1411 drives the moving rod 1410 to move upward and compress the spring. When the groove position of the groove block 148 is opposite to the position of the inclined strip 1411, the moving rod 1410 will move downward through the spring reset, so as to fix the position of the collection box 131, ensure the normal operation of the device, and avoid the wrong position of the collection box 131 affecting the normal operation of other components.

[0021] Working principle: When discharging the electric heating wires, the shaking plate 134 rotates upward to drive the chamfered plate 144 to move upward. The sliding plate 142 moves to the right to drive the pushing plate 143 to move to the right. When the pushing plate 143 moves to the right, it will push the piled-up electric heating wires apart, making the electric heating wires more evenly distributed inside the collection box 131, thereby improving the space utilization rate inside the collection box 131. During the process of placing the collection box 131, the collection box 131 will drive the fixed column 147 to move. The movement of the fixed column 147 drives the groove block 148 to move, so as to fix the position of the collection box 131, ensure the normal operation of the device, and avoid the wrong position of the collection box 131 affecting the normal operation of other components.
