[0013] In summary, 1. The present invention adopts the design of the bottom plate, the feeding rack, the buffer mechanism, the auxiliary wheel assembly, the extruder, the first cooling mechanism, the wire diameter measuring mechanism, the inkjet printer, the second cooling mechanism, the electric spark generator, the temporary storage rack, the adjustment assembly, the quick maintenance assembly, the motor and the screw rod. The feeding rack is used to place the finished wire core, and the buffer mechanism is used to buffer the cable to compensate for the tension during the cable transportation and prevent the cable from breaking or piling up due to the tension problem during the transportation process;

[0014] The wire core after passing through the buffer mechanism passes through the extruder to form a finished cable;

[0022] 2. The present invention adopts the design of a fixed shell, a lever, a limit block, a movable plate, a third spring push rod and a movable plate. When the motor drives the movable plate to move on the surface of the temporary storage rack by using a screw rod, the fixed shell will rotate along with the rotation of the rotating wheel, and in the whole process, the fixed shell will drive the four groups of levers to continuously push the limit block, so that the limit block is limited inside the temporary storage rack by the movable plate, the third spring push rod is used to drive the limit block to reset, and the limit block and the movable plate are connected by screws, which can speed up the time of replacing the limit block. Because the limit block is in direct contact with the temporary storage rack, wear will occur, thereby achieving the effect of preventing the adjustment component from being unusable for a long time due to wear.

[0023] 3. The present invention adopts the design of the rotating wheel, rotating column, sphere, center rod, push rod, connecting plate, first spring top rod, telescopic spring, transmission block, second spring top rod, limit plate, inclined plate and inclined block. When the rotating wheel moves and rotates, it will drive the rotating column and the transmission block to rotate. Multiple groups of transmission blocks are spliced ​​together for temporary storage of cables. The limit plate is used to limit the movement of the rotating wheel. When the rotating wheel moves to a certain position, the sphere will contact the inclined plate, so that the sphere drives the center rod to move inside the rotating column, and drives the push rod to move and push the inclined block. Since one side of the inclined block surface is an inclined surface, the transmission block can be used to The second spring push rod extends outward to adjust the relative positions of the corresponding four groups of transmission blocks and temporarily store the cables. This method is suitable for use when the temporary storage rack cannot store more cables, and the transmission blocks can be reasonably adjusted according to the contact position of the sphere and the inclined plate to prevent cable accumulation or breakage. When the surface of some transmission blocks cannot be adjusted due to the storage of cables, in order to prevent jamming, the push rod will be moved by the first spring push rod, and the telescopic spring is used to drive the center rod to reset when the adjustment component is not in use, thereby effectively preventing the cable accumulation caused by the inability of the temporary storage rack to store more cables.

[0047] The above scheme is adopted: through the design of the fixed shell 1301, the lever 1302, the limit block 1303, the movable plate 1304, the third spring push rod 1305 and the movable plate 1306, when the motor 14 drives the movable plate 1306 to move on the surface of the temporary storage rack 11 by using the screw rod 15, the fixed shell 1301 will rotate along with the rotation of the rotating wheel 1201, and in the whole process, the fixed shell 1301 will drive the four groups of levers 1302 to continuously push the limit block 1303, so that the limit block 1303 is limited inside the temporary storage rack 11 by the movable plate 1304, the third spring push rod 1305 is used to drive the limit block 1303 to reset, and the limit block 1303 and the movable plate 1304 are connected by screws, which can speed up the time of replacing the limit block 1303. Because the limit block 1303 is in direct contact with the temporary storage rack 11, wear will occur, thereby achieving the effect of preventing the adjustment component 12 from being unusable for a long time due to wear.

[0048] refer to Figure 6 , Figure 8 and Fig. 9The adjusting assembly 12 includes an inclined plate 1212, a limiting plate 1211, a rotating wheel 1201, a central rod 1204, a telescopic spring 1208 and a conveying block 1209. The inclined plate 1212 is fixedly connected to one end of one side of the inner wall of the temporary storage rack 11, and two groups of limiting plates 1211 are fixedly connected to the bottom of the temporary storage rack 11. The rotating wheel 1201 is fixedly connected to one side of the surface of the fixed shell 1301; a rotating column 1202 is fixedly connected to the middle of one side of the surface of the rotating wheel 1201, and a plurality of groups of holes are opened on the surface of the rotating column 1202. The central rod 1204 is movably connected to the inside of the rotating column 1202, and a sphere 1203 is fixedly connected to one end of the surface of the central rod 1204; the telescopic spring 1208 is fixedly connected between the central rod 1204 and the rotating column 1202, and the central rod 1 Several groups of connecting plates 1206 are fixedly connected to the four sides of the surface 204, one side of the surface of several groups of connecting plates 1206 is fixedly connected to the first spring push rod 1207, the piston ends of several groups of first spring push rod 1207 are fixedly connected to the push rod 1205, and the push rod 1205 and the hole are movably connected; several groups of second spring push rods 1210 are fixedly connected to the surface of the rotating column 1202, several groups of second spring push rods 1210 are respectively arranged on one side of several groups of holes, several groups of transmission blocks 1209 are respectively fixedly connected to the piston ends of the corresponding two groups of second spring push rods 1210, one side of the surface of several groups of transmission blocks 1209 is fixedly connected to the inclined block 1213, and the inclined block 1213 is located between the second spring push rod 1210 and the push rod 1205.

[0049] The above scheme is adopted: through the design of the rotating wheel 1201, the rotating column 1202, the ball 1203, the central rod 1204, the push rod 1205, the connecting plate 1206, the first spring top rod 1207, the telescopic spring 1208, the transmission block 1209, the second spring top rod 1210, the limiting plate 1211, the inclined plate 1212 and the inclined block 1213, the rotating wheel 1201 will drive the rotating column 1202 and the transmission block 1209 to rotate during the movement and rotation, and multiple groups of transmission blocks 1209 are spliced ​​together for temporary storage of cables. The limiting plate 1211 is used to limit the movement of the rotating wheel 1201. When the rotating wheel 1201 moves to a certain position, the ball 1203 will contact the inclined plate 1212, so that the ball 1203 drives the central rod 1204 to move inside the rotating column 1202, and drives the push rod 1205 to move and adjust the inclined block 1213. 13 is pushed, and since one side of the surface of the inclined block 1213 is an inclined surface, the transmission block 1209 is extended outward by the second spring top rod 1210, so as to adjust the relative positions of the corresponding four groups of transmission blocks 1209 and temporarily store the cables. This method is suitable for use when the temporary storage rack 11 cannot store more cables, and the transmission block 1209 can be reasonably adjusted according to the contact position between the ball 1203 and the inclined plate 1212 to prevent the cables from piling up or breaking. When the surface of some transmission blocks 1209 cannot be adjusted due to the presence of cables, in order to prevent them from getting stuck, the push rod 1205 is moved by the first spring top rod 1207, and the telescopic spring 1208 is used to drive the center rod 1204 to reset when the adjustment component 12 is not in use, thereby effectively preventing the cables from piling up due to the inability of the temporary storage rack 11 to store more cables.

[0050] Working principle:

[0051] During use, when the motor 14 drives the movable plate 1306 to move on the surface of the temporary storage rack 11 by means of the screw rod 15, the fixed shell 1301 will rotate along with the rotation of the rotating wheel 1201, and in the whole process, the fixed shell 1301 will drive the four groups of levers 1302 to continuously push the limit block 1303, so that the limit block 1303 is limited inside the temporary storage rack 11 by means of the movable plate 1304, the third spring push rod 1305 is used to drive the limit block 1303 to reset, and the limit block 1303 and the movable plate 1304 are connected by screws, so that The time for replacing the limit block 1303 is accelerated. Because the limit block 1303 is in direct contact with the temporary storage rack 11, wear will occur. Through the design of the rotating wheel 1201, the rotating column 1202, the ball 1203, the central rod 1204, the push rod 1205, the connecting plate 1206, the first spring top rod 1207, the telescopic spring 1208, the transmission block 1209, the second spring top rod 1210, the limit plate 1211, the inclined plate 1212 and the inclined block 1213, the rotating wheel 1201 will drive the rotating column 1202 and the transmission block 1209 during the movement and rotation. 9 is rotated, and multiple groups of transmission blocks 1209 are spliced ​​together for temporary storage of cables. The limit plate 1211 is used to limit the movement of the rotating wheel 1201. When the rotating wheel 1201 moves to a certain position, the ball 1203 will contact the inclined plate 1212, so that the ball 1203 drives the central rod 1204 to move inside the rotating column 1202, and drives the push rod 1205 to move and push the inclined block 1213. Since one side of the surface of the inclined block 1213 is an inclined surface, the transmission block 1209 is extended outward by the second spring push rod 1210, thereby adjusting The relative positions of the four groups of transmission blocks 1209 correspond to each other and the cables are temporarily stored. This method is suitable for use when the temporary storage rack 11 cannot store more cables, and the transmission blocks 1209 can be reasonably adjusted according to the contact position of the sphere 1203 and the inclined plate 1212 to prevent the cables from piling up or breaking. When the surface of some transmission blocks 1209 cannot be adjusted due to the presence of cables, in order to prevent jamming, the push rod 1205 will be moved by the first spring top rod 1207, and the telescopic spring 1208 is used to drive the center rod 1204 to reset when the adjustment component 12 is not in use.

[0052] To sum up: this cable sheath forming production line, through the structure of fixed shell 1301, lever 1302, limit block 1303, movable plate 1304, third spring top rod 1305 and movable plate 1306, solves the problem that although the existing cable sheath forming production line has made certain progress, there are still some significant problems. First, the equipment integration is low, and there is a lack of effective coordination between the various devices, resulting in low overall production efficiency. Secondly, the degree of automation is not high enough, and it relies on a lot of manual intervention, which increases production costs and management difficulty. Finally, the intelligence level of the equipment is limited, and it is impossible to monitor and adjust production parameters in real time, resulting in large fluctuations in product quality.
