Description

Technical Field

[0001] This utility model relates to the technical field of cable production, and in particular to a rounding device for armored cables. Background Technology

[0002] During the production of armored cables, the outer insulation layer needs to be rounded. Chinese invention patent application CN112542278B discloses a rounding device for armored cables. This device includes a frame, a predetermined number of rounding mechanisms, and a vibration mechanism. The vibration head in the vibration mechanism vibrates and strikes the armored cable located above the cable inlet, making the fire-retardant powder filler more uniform, compact, and dense. Two of the predetermined number of rounding mechanisms, staggered on the support frame, clamp the armored cable tightly. Each rounding cylinder has an arc-shaped groove around its circumference that matches the outer diameter of the armored cable. The relative rotation of the two rounding cylinders rounds the armored cable, simultaneously pulling it. This improves the uniformity and compactness of the fire-retardant powder filler filling, enhances fire resistance, improves the roundness of the armored cable, and further improves the tensile and compressive strength of various parts of the armored cable, making it safer to use.

[0003] However, the aforementioned sizing equipment has a fixed sizing cylinder when sizing armored cables, and it cannot rotate around the cable at a certain angle. This causes extrusion marks to appear on the surface of the insulation layer of the armored cable at the joint of multiple sizing cylinders, reducing the surface quality of the cable. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rounding device for armored cables that reduces extrusion marks and improves the surface quality of the cable by continuously changing the rounding angle and position of the insulation layer of the armored cable.

[0005] This utility model discloses a device for rounding armored cables, including a frame and multiple rounding wheels; it also includes a mounting frame, a drive motor, two lifting rods, two shafts, and a drive mechanism. The multiple rounding wheels are rotatably mounted in the middle of the mounting frame, and each rounding wheel has an arc-shaped groove for rounding. The drive motor is mounted on the mounting frame and drives the multiple rounding wheels to rotate synchronously relative to each other. The two lifting rods are slidably inserted into the left and right sides of the frame, respectively. The drive mechanism is mounted on the frame and drives the two lifting rods to rise and fall alternately. The two shafts are slidably inserted into the left and right sides of the mounting frame, and the upper ends of the two lifting rods are rotatably connected to the two shafts, respectively. During operation, the armored cable passes through the arc-shaped grooves of multiple circular rollers. The drive motor drives the multiple circular rollers to rotate synchronously relative to each other, causing the multiple circular rollers to roll and round the outer layer of the armored cable. At the same time, the drive mechanism drives two lifting rods to alternately raise or lower, so that the upper ends of the two lifting rods drive two shafts to alternately raise and lower. The two shafts drive the left and right ends of the mounting frame to alternately raise and lower, so that the mounting frame drives the multiple circular rollers to reciprocate around the armored cable. This causes the multiple circular rollers to continuously change the round angle and position of the insulation layer of the armored cable, thereby reducing the extrusion marks on the surface of the insulation layer of the armored cable and improving the surface quality of the cable.

[0006] Preferably, it also includes two springs, each spring being fitted onto one of the two shafts. One end of each spring is connected to one of the two shafts, and the other end of each spring is connected to the left and right ends of the mounting frame. The mounting frame is elastically connected to the two shafts via the two springs, so that when the mounting frame reciprocates around the armored cable, the two shafts slide relative to the left and right sides of the mounting frame, compressing and releasing the two springs. The two springs elastically support the mounting frame, improving its stability.

[0007] Preferably, the drive mechanism includes a geared motor, a turntable, a pull rod, a rocker arm, and a vertical rod. The geared motor is mounted on the frame, and its output shaft is concentric with the turntable. The upper end of the pull rod is rotatably connected to the outer edge of the turntable, and the lower end of the pull rod is rotatably connected to one end of the rocker arm. The two ends of the rocker arm are in sliding contact with the lower ends of the two lifting rods, respectively. The upper end of the vertical rod is connected to the frame, and the lower end of the vertical rod is rotatably connected to the middle of the rocker arm. The geared motor drives the turntable to rotate, which in turn causes the upper end of the pull rod to rotate around the turntable's axis, thereby causing the lower end of the pull rod to reciprocate up and down. The lower end of the pull rod causes the two ends of the rocker arm to swing back and forth relative to each other around the lower end of the vertical rod. When the two ends of the rocker arm swing, they respectively drive the two lifting rods to alternately reciprocate up and down, realizing the alternating reciprocating up and down drive of the two lifting rods, which is practical.

[0008] Preferably, it also includes a vibration motor, which is mounted on the mounting frame; when the vibration motor is started, it vibrates the mounting frame and multiple round wheels, thereby ensuring that the fire-retardant powder filler inside the armored cable is filled evenly and compactly.

[0009] Preferably, the assembly also includes multiple track wheels, a complete circle, and multiple round wheels II. The multiple track wheels are rotatably mounted on the frame, the complete circle is rolled on the multiple track wheels via an outer track, and the multiple round wheels II are rotatably mounted inside the complete circle. Each of the multiple round wheels II has an arc-shaped groove I for rounding. The armored cable extends from between the multiple round wheels I and passes through the arc-shaped groove I between the multiple round wheels II. The complete circle rolls on the multiple track wheels, and the complete circle drives the multiple round wheels II to rotate around the armored cable. When the armored cable is conveyed backward, the multiple round wheels II rotate to perform secondary rolling and rounding on the outer layer of the armored cable, improving the rounding quality.

[0010] Preferably, it also includes a gear ring, a gear, and a rack. The gear ring is mounted on the outer wall of the entire circle. The gear is rotatably mounted on the frame via a bracket and meshes with the gear ring. The rack is mounted on the lifting rod via a bracket and meshes with the gear. When the lifting rod reciprocates, it drives the rack to reciprocate. The rack meshes with the gear and drives it to rotate reciprocally. The gear meshes with the gear and drives the gear ring, thereby causing the gear ring to drive the entire circle to rotate reciprocally. The entire circle drives multiple circular wheels to roll the outer layer of the armored cable at different angles to form the entire circle, improving the quality of the entire circle.

[0011] Preferably, it also includes a heater and a temperature detector. The heater is mounted on the circular ring, which is used to heat the outer layer of the armored cable. The temperature detector is mounted on the circular ring and is used to detect the temperature of the armored cable. The heater heats the armored cable that enters between multiple circular rings. The temperature detector detects the temperature of the armored cable and adjusts the heating power of the heater according to the detected temperature value. The softened outer layer of the armored cable is easier to be shaped by the circular ring, improving the circular ring effect.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the armored cable passes through the arc-shaped groove of multiple circular wheels. The drive motor drives the multiple circular wheels to rotate synchronously relative to each other, so that the multiple circular wheels roll and round the outer layer of the armored cable. At the same time, the drive mechanism drives two lifting rods to alternately raise or lower, so that the upper ends of the two lifting rods drive two shafts to alternately raise and lower. The two shafts drive the left and right ends of the mounting frame to alternately raise and lower, so that the mounting frame drives the multiple circular wheels to reciprocate around the armored cable. This causes the multiple circular wheels to continuously change the circular angle and position of the insulation layer of the armored cable, thereby reducing the extrusion marks on the surface of the insulation layer of the armored cable and improving the surface quality of the cable.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1

[0021] like Figures 1 to 4As shown, a rounding device for armored cables includes a frame 1 and multiple rounding wheels 2; it also includes a mounting frame 3, a drive motor 4, two lifting rods 5, two shafts 6, and a drive mechanism. The multiple rounding wheels 2 are rotatably mounted in the middle of the mounting frame 3, and each wheel 2 has an arc-shaped groove for rounding. The drive motor 4 is mounted on the mounting frame 3 and drives the multiple rounding wheels 2 to rotate synchronously relative to each other. The two lifting rods 5 are slidably inserted into the left and right sides of the frame 1, respectively. The drive mechanism is mounted on the frame 1 and drives the two lifting rods 5 to rise and fall alternately. The two shafts 6 are slidably inserted into the left and right sides of the mounting frame 3, and the upper ends of the two lifting rods 5 are rotatably connected to the two shafts 6, respectively. It also includes two springs 7. Two springs 7 are respectively fitted onto two shafts 6, one end of each spring 7 is connected to the two shafts 6, and the other end of each spring 7 is connected to the left and right ends of the mounting frame 3 respectively; the drive mechanism includes a geared motor 8, a turntable 9, a pull rod 10, a rocker 11, and a vertical rod 12. The geared motor 8 is mounted on the frame 1, and the output shaft of the geared motor 8 is concentric with the turntable 9. The upper end of the pull rod 10 is rotatably connected to the outer edge of the turntable 9, and the lower end of the pull rod 10 is rotatably connected to one end of the rocker 11. The two ends of the rocker 11 are in sliding contact with the lower ends of the two lifting rods 5 respectively. The upper end of the vertical rod 12 is connected to the frame 1, and the lower end of the vertical rod 12 is rotatably connected to the middle of the rocker 11; it also includes a vibration motor 13, which is mounted on the mounting frame 3.

[0022] During operation, the armored cable passes through the arc-shaped grooves of multiple circular rollers 2. The drive motor 4 drives the multiple circular rollers 2 to rotate synchronously relative to each other, so that the multiple circular rollers 2 roll and round the outer layer of the armored cable. At the same time, the reduction motor 8 drives the turntable 9 to rotate. The turntable 9 drives the upper end of the pull rod 10 to rotate around the rotation axis of the turntable 9, thereby driving the lower end of the pull rod 10 to reciprocate up and down. The lower end of the pull rod 10 drives the two ends of the rocker arm 11 to swing back and forth relative to each other around the lower end of the vertical rod 12. When the two ends of the rocker arm 11 swing, they respectively drive the two lifting rods 5 to rise or fall alternately, so that the upper ends of the two lifting rods 5 respectively drive the two shafts 6 to rise and fall alternately. The two shafts 6 respectively drive the left and right ends of the mounting frame 3 to rise and fall alternately. The mounting frame 3 is raised and lowered, causing multiple circular wheels 2 to reciprocate around the armored cable. The mounting frame 3 is elastically connected to two shafts 6 via two springs 7. When the mounting frame 3 reciprocates around the armored cable, the two shafts 6 slide relative to the left and right sides of the mounting frame 3, compressing and releasing the two springs 7. The two springs 7 elastically support the mounting frame 3, thereby causing the multiple circular wheels 2 to continuously change the circular angle and position of the armored cable insulation layer, thus reducing the extrusion marks on the surface of the armored cable insulation layer. The vibration motor 13 is started to vibrate the mounting frame 3 and the multiple circular wheels 2, thereby ensuring that the fireproof powder filler inside the armored cable is filled evenly and compactly, improving the surface quality of the cable.

[0023] Example 2

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, based on Embodiment 1, it also includes multiple track wheels 14, a complete circle 15, and multiple complete circle wheels 16. The multiple track wheels 14 are rotatably mounted on the frame 1. The complete circle 15 is rolled on the multiple track wheels 14 via an outer track. The multiple complete circle wheels 16 are rotatably mounted inside the complete circle 15. Each of the multiple complete circle wheels 16 has an arc-shaped groove for forming a circle on its wheel surface. It also includes a gear ring 17, a gear 18, and a rack 19. The gear ring 17 is mounted on the outer wall of the complete circle 15. The gear 18 is rotatably mounted on the frame 1 via a bracket and meshes with the gear ring 17. The rack 19 is mounted on the lifting rod 5 via a bracket and meshes with the gear 18.

[0025] The armored cable extends from between multiple circular wheels 12 and passes through the arc groove between multiple circular wheels 16. The circular wheel 15 rolls on multiple track wheels 14, driving the multiple circular wheels 16 to rotate around the armored cable. When the armored cable is conveyed backward, the multiple circular wheels 16 rotate to perform secondary rolling and rounding on the outer layer of the armored cable, improving the rounding quality. When the lifting rod 5 reciprocates, it drives the rack 19 to reciprocate. The rack 19 meshes with the drive gear 18 to reciprocate. The gear 18 meshes with the drive gear ring 17, thereby causing the gear ring 17 to drive the circular wheel 15 to reciprocate. The circular wheel 15 drives the multiple circular wheels 16 to roll and round the outer layer of the armored cable at different angles, improving the rounding quality.

[0026] Example 3

[0027] like Figures 1 to 5 As shown, based on Embodiment 2, it also includes a heater 20 and a temperature detector 21. The heater 20 is mounted on the circular ring 15, which is used to heat the outer layer of the armored cable. The temperature detector 21 is mounted on the circular ring 15 and is used to detect the temperature of the armored cable. The heater 20 heats the armored cable that enters between the multiple circular rings 16. The temperature detector 21 detects the temperature of the armored cable and adjusts the heating power of the heater 20 according to the detected temperature value. The softened outer layer of the armored cable is easier to be shaped by the circular ring, thus improving the circular ring effect.

[0028] like Figures 1 to 5As shown, this utility model discloses a rounding device for armored cables. During operation, the armored cable first passes through the arc-shaped grooves of multiple rounding wheels 2. A drive motor 4 drives the multiple rounding wheels 2 to rotate synchronously relative to each other, causing the wheels to roll and round the outer layer of the armored cable. Then, a reduction motor 8 drives a turntable 9 to rotate. The turntable 9 causes the upper end of a pull rod 10 to rotate around its axis, thereby causing the lower end of the pull rod 10 to reciprocate. The lower end of the pull rod 10 causes the two ends of a rocker arm 11 to swing relative to each other around the lower end of a vertical rod 12. When the two ends of the rocker arm 11 swing, they respectively cause two lifting rods 5 to alternately rise and fall, causing the upper ends of the two lifting rods 5 to alternately rise and fall on two shafts 6. Then, the two shafts 6... The mounting frame 3 is raised and lowered alternately at both ends, causing multiple circular wheels 1 2 to rotate back and forth around the armored cable. This causes the multiple circular wheels 1 2 to continuously change the circular angle and position of the insulation layer of the armored cable. After the armored cable extends from between the multiple circular wheels 1 2, it passes through the arc groove 1 between the multiple circular wheels 2 16. The circular circle 15 rolls on the multiple track wheels 14. The circular circle 15 drives the multiple circular wheels 2 16 to rotate around the armored cable. Finally, when the armored cable is conveyed backward, the multiple circular wheels 2 16 rotate to perform a secondary rolling and circularization of the outer layer of the armored cable. By continuously changing the circular angle and position of the insulation layer of the armored cable, the extrusion marks on the surface of the insulation layer of the armored cable can be reduced.

[0029] The main functions achieved by this utility model are:

[0030] 1. By continuously changing the circular angle and position of the insulation layer of the armored cable, the extrusion marks are reduced and the surface quality of the cable is improved;

[0031] 2. The armored cable is rolled into a round shape twice to improve the rounding efficiency;

[0032] 3. By heating the cable, the rounding effect is improved.

[0033] The armored cable rounding device of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the desired effect can be implemented. The rounding wheel 1 2, mounting frame 3, drive motor 4, spring 7, reduction motor 8, turntable 9, vibration motor 13, track wheel 14, rounding circle 15, rounding wheel 2 16, gear ring 17, gear 18, rack 19, heater 20, and temperature detector 21 of this utility model are commercially available.
