Description

Technical Field

[0001] This utility model belongs to the field of cable production technology, and specifically relates to a cable hot-press printing wheel. Background Technology

[0002] Currently, all cable products are required to have the manufacturer's name, product model, rated voltage, and other continuous markings printed on their surfaces. Additionally, products subject to production license management must also display a production license mark and number, and products subject to mandatory certification must display a CCC mark and factory number. These printing requirements must comply with the relevant cable product standards and GB6995-1986 "Identification Marking of Wires and Cables". The main methods for marking cable product surfaces are ink printing (which can be further divided into ink roller printing and inkjet printing) and thermoforming printing (which can be further divided into thermoforming ribbon printing and thermoforming roller printing).

[0003] In the existing technology, during the hot pressing of high-voltage cables, the printing wheel is generally integrally formed, and the engravings on the printing wheel are mostly engraved on the outer side wall. When different models and specifications of cables need to be printed, the entire printing wheel often needs to be replaced, which is cumbersome and inefficient.

[0004] Therefore, improvements are urgently needed. Utility Model Content

[0005] To address the aforementioned deficiencies in existing technologies, this utility model provides a cable hot-press printing wheel, comprising a left printing wheel, a right printing wheel, an adjusting mechanism, and a lifting mechanism. Based on the cable's perpendicular inward movement along the paper, the left and right printing wheels are respectively positioned on the left and right sides of the cable. The left printing wheel includes a left annular portion and a left disc-shaped portion. Three first protrusions are evenly arranged on the inner wall of the left annular portion, and three L-shaped first slots are evenly formed on the outer edge of the left disc-shaped portion. The positions of the three first slots not only correspond one-to-one with the positions of the three first protrusions, but also correspond to the positions of the first protrusions. The right printing wheel includes a right annular part and a right disc-shaped part. Three second protrusions are evenly arranged on the inner side wall of the right annular part, and three inverted L-shaped second slots are evenly opened on the outer edge of the right disc-shaped part. The positions of the three second slots not only correspond one-to-one with the positions of the three second protrusions, but also match the second protrusions. The center of the left disc-shaped part and the right disc-shaped part are both provided with a central hole, and a rotating shaft is fixedly installed at their central holes. The bottom end of the rotating shaft is rotatably connected to the base. In addition, the outer side walls of the left annular part and the right annular part are provided with intaglio characters or patterns.

[0006] The adjustment mechanism is located below the two printing wheels and is used to adjust the distance between the two printing wheels.

[0007] The lifting mechanism is located below the adjusting mechanism and is used to adjust the height of the two printing wheels and the adjusting mechanism.

[0008] Optionally, the adjustment mechanism includes a base plate, two vertical plates, a horizontal slide rail, a double-acting screw, and two slide blocks. The two vertical plates are fixed to the left and right ends above the base plate, respectively. The horizontal slide rail is installed on the top surface of the base plate. The double-acting screw is rotatably connected between the two vertical plates and located above the horizontal slide rail. The left and right ends of the double-acting screw pass through the two slide blocks, and the two slide blocks are slidably connected to the double-acting screw through the nut pair of the double-acting screw. The bottom ends of the two slide blocks are slidably connected to the horizontal slide rail, and the top ends of the two slide blocks are fixedly connected to the bottom surfaces of the two chassis, respectively.

[0009] Optionally, one end of the bidirectional lead screw passes through the vertical plate and is fitted with a hand crank.

[0010] Optionally, limit blocks are provided at both ends of the horizontal slide rail.

[0011] Specifically, the limit block is used to limit the movement of the slide.

[0012] Optionally, the lifting mechanism includes a base and a hydraulic cylinder, with the cylinder seat of the hydraulic cylinder fixed on the base and the piston rod of the hydraulic cylinder fixedly connected to the bottom surface of the base plate.

[0013] This invention also includes other components that enable the normal use of a cable hot-press printing wheel, all of which are conventional techniques in the art. Furthermore, any devices or components not specified in this invention employ conventional techniques in the art, such as hydraulic cylinders.

[0014] The working principle of this utility model is as follows: First, based on the position of the extruder outlet, the height of the two printing wheels is adjusted by controlling the extension or retraction of the piston rod of the hydraulic cylinder; then, according to the cable model and specifications, the left and right annular portions with corresponding fonts or patterns are selected. The first protrusion of the left annular portion is inserted from top to bottom into the first slot of the left disc-shaped portion, and then the left annular portion is rotated counterclockwise until it is fully rotated. Next, the second protrusion of the right annular portion is inserted from top to bottom into the second slot of the right disc-shaped portion, and then the right annular portion is rotated clockwise until it is fully rotated. Finally, based on the outer diameter of the cable, the distance between the two printing wheels is adjusted by the adjusting mechanism. (Specific steps follow.) The process is as follows: Manually rotate the hand crank to drive the bidirectional lead screw, causing the two slides to move towards or away from each other, thereby bringing the two printing wheels closer together or further apart, thus adjusting their spacing. After the above adjustment is completed, the cable exits from the extruder and passes between the two printing wheels, causing the left printing wheel to rotate counterclockwise and the right printing wheel to rotate clockwise, thus allowing the two printing wheels to heat-press the lettering onto the cable. When it is necessary to change the heat-pressed lettering, simply remove the left annular part clockwise and the right annular part counterclockwise, and replace them with new left and right annular parts. The disassembly and assembly are convenient and the replacement efficiency is high.

[0015] The advantages of this utility model are that the printing wheel adopts a split design, which is convenient for disassembly and assembly, and the font replacement is quick and convenient, eliminating the trouble of replacing the entire printing wheel and improving the replacement efficiency; the adjustment mechanism makes it easy to adjust the distance between the two printing wheels to adapt to cables of different diameters and improve the applicability.

The right printing wheel 2 includes a right annular portion and a right disc-shaped portion 8. Three second protrusions are evenly arranged on the inner sidewall of the right annular portion. Three inverted L-shaped second slots 10 are evenly opened on the outer edge of the right disc-shaped portion 8. The positions of the three second slots 10 not only correspond one-to-one with the positions of the three second protrusions, but also match the second protrusions. The center of the left disc-shaped portion 4 and the right disc-shaped portion 8 are both provided with a center hole 11, and a rotating shaft 12 is fixedly installed at their center holes 11. The bottom end of the rotating shaft 12 is rotatably connected to the base 13. In addition, the outer sidewalls of the left annular portion 3 and the right annular portion are provided with intaglio characters or patterns.

[0025] An adjustment mechanism is located below the two printing wheels and is used to adjust the distance between the two printing wheels. The adjustment mechanism includes a base plate 14, two upright plates 15, a horizontal slide rail 16, a double-acting screw 17, and two slide blocks 18. The two upright plates 15 are fixed to the left and right ends above the base plate 14, respectively. The horizontal slide rail 16 is installed on the top surface of the base plate 14. The double-acting screw 17 is rotatably connected between the two upright plates 15 and located above the horizontal slide rail 16. The left and right ends of the double-acting screw 17 pass through the two slide blocks 18, and the two slide blocks 18 are slidably connected to the double-acting screw 17 through the nut pair of the double-acting screw 17. The bottom ends of the two slide blocks 18 are slidably connected to the horizontal slide rail 16, and the top ends of the two slide blocks 18 are fixedly connected to the bottom surfaces of the two base plates 13, respectively.

[0026] In addition, one end of the bidirectional lead screw 17 passes through the vertical plate 15 and is equipped with a hand crank turntable 19. Limit blocks 20 are provided at both ends of the horizontal slide rail 16, and the limit blocks 20 are used to limit the movement of the slide block 18.

[0027] The lifting mechanism is located below the adjusting mechanism and is used to adjust the height of the two printing wheels and the adjusting mechanism.

[0028] The working principle of this utility model is as follows: First, based on the position of the extruder outlet, the height of the two printing wheels is adjusted by controlling the hydraulic cylinder 22 to extend or retract the piston rod; then, based on the model and specifications of the cable 23, the left annular part 3 and the right annular part with corresponding fonts or patterns are selected. The first protrusion 5 of the left annular part 3 is inserted from top to bottom into the first slot 6 of the left disc-shaped part 4, and then the left annular part 3 is rotated counterclockwise until it is fully rotated. Then, the second protrusion of the right annular part is inserted from top to bottom into the second slot 10 of the right disc-shaped part 8, and then the right annular part is rotated clockwise until it is fully rotated. Finally, based on the outer diameter of the cable 23, the distance between the two printing wheels is adjusted by the adjusting mechanism. (Specific steps follow.) The process is as follows: Manually rotate the hand crank 19 to drive the bidirectional lead screw 17 to rotate, causing the two slides 18 to move towards or away from each other, thereby bringing the two printing wheels closer together or further apart, thus adjusting their spacing. After the above steps are completed, the cable 23 exits from the extruder outlet and passes between the two printing wheels, causing the left printing wheel 1 to rotate counterclockwise and the right printing wheel 2 to rotate clockwise, thus allowing the two printing wheels to heat-press the cable 23 with characters. When it is necessary to change the heat-pressed characters, simply remove the left annular part 3 in a clockwise direction and the right annular part in a counterclockwise direction, and replace it with a new left annular part 3 and a new right annular part. The disassembly and assembly are convenient and the replacement efficiency is high.
