[0003] During the vulcanization process, traditional vulcanization production lines usually use warm water tanks and hot steam for vulcanization.

[0034] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1-13 A vulcanization production line for cable production is shown, comprising a wire unwinder 1, a rubber extruder 2, a vulcanization box 3, a cooling box 4 and a wire take-up device 5; a vulcanization tank 301 is provided in the vulcanization box 3, a first shearing assembly 7 is provided at the end of the vulcanization tank 301 and is fixedly connected to a fixed frame 8 and the inner wall of the vulcanization tank 301, a second shearing assembly 9 is provided on one side of the first shearing assembly 7, the second shearing assembly 9 is connected to a moving block 10 slidably connected to the vulcanization box 3, the moving block 10 is threadedly connected to an axial screw rod 11, the axial screw rod 11 is connected to a first motor 12, the first motor 12 drives the moving block 10 to move along the length direction of the vulcanization box 3 through the axial screw rod 11, and the moving block 10 drives the second shearing assembly 9 to move along the length direction of the vulcanization box 3;

[0037] The first shearing assembly 7 includes a mounting cylinder 14 and a mounting cover 17 fixedly connected to the mounting cylinder 14. A rotating cylinder 15 rotatably connected thereto is mounted in the mounting cylinder 14. Clamping roller assemblies 16 equidistantly distributed circumferentially are mounted on the inner side of the rotating cylinder 15. The clamping roller assemblies 16 distributed circumferentially clamp and guide the cable body 6 circumferentially. A worm gear ring 18 is sleeved and fixed on the outer side of the rotating cylinder 15. The worm gear ring 18 is meshed with a worm 19. A second motor 20 is connected to the upper end of the worm 19. The second motor 20 drives the rotating cylinder 15 to rotate through the worm 19 and the worm gear ring 18. The rotating cylinder 15 drives the clamping roller assembly 16 thereon to make a circular motion.

[0038] The clamping roller assembly 16 includes a clamping wheel 1601 abutting against the cable body 6, the clamping wheel 1601 is rotatably connected to a wheel frame 1602, the wheel frame 1602 is connected to a moving frame 1603 extending into the rotating cylinder 15, and the moving frame 1603 is threadedly connected to a radial screw rod 1604 installed in the rotating cylinder 15; the outer end of the radial screw rod 1604 is fixedly connected to a passive gear 21, the passive gear 21 is meshed with a transmission gear ring 22 nested in the rotating cylinder 15, the transmission gear ring 22 is meshed with a driving gear 23, and the driving gear 23 is connected to a third motor 24 installed in the rotating cylinder 15, the third motor 24 drives the radial screw rod 1604 to rotate through the driving gear 23, the transmission gear ring 22 and the passive gear 21, and the radial screw rod 1604 drives the clamping wheel 1601 to reciprocate radially through the moving frame 1603 and the wheel frame 1602;

[0039] The structure of the second shearing assembly 9 is the same as that of the first shearing assembly 7 .

[0040] For details, please refer to Figure 11-13 When the cable is vulcanized, first, a heat source is introduced into the vulcanization tank 301; then, the cable body 6 is directional-guided through the first shearing assembly 7. More specifically, according to the diameter of the cable body 6, the third motor 24 of the first shearing assembly 7 is started, and the third motor 24 drives the radial screw 1604 to rotate through the driving gear 23, the transmission gear ring 22 and the passive gear 21. The radial screw 1604 drives the clamping wheel 1601 to move toward the axis of the cable body 6 through the moving frame 1603 and the wheel frame 1602. The clamping wheels 1601 distributed in a circle abut against the circumferential side wall of the cable body 6, so that the cable body 6 close to the first shearing assembly 7 cannot self-twist and can only move along its own axial direction, thereby realizing directional guidance;

[0041] The third motor 24 of the second shearing assembly 9 is started. Similarly, the circumferentially distributed clamping wheels 1601 of the second shearing assembly 9 are brought into contact with the circumferential side of the cable body 6. Then the second motor 20 of the second shearing assembly 9 is started. The second motor 20 drives the rotating cylinder 15 to periodically reciprocate through the worm 19 and the worm ring 18. The rotating cylinder 15 drives the circumferentially distributed clamping wheels 1601 to perform periodic reciprocating circumferential rotation. The clamping wheels 1601 drive the cable body 6 inside to twist. The rubber sleeve is subjected to the shearing effect of the external force during the processing, so that the rubber sleeve is twisted. The molecular chains are deformed and entangled with each other to form a mesh structure, which promotes the vulcanization of the deep internal position of the rubber sleeve, thereby improving the vulcanization effect of the cable body 6. At the same time, the first motor 12 is started, and the first motor 12 drives the axial screw 11 to reciprocate, and the axial screw 11 drives the moving block 10 to reciprocate in the vulcanization tank 301. The moving block 10 drives the second shearing component 9 to reciprocate horizontally in the vulcanization tank 301, and twists each position of the cable body 6 flowing through the vulcanization tank 301, so as to further improve the uniformity of the shearing action and improve the vulcanization effect.

[0042] Compared with the traditional vulcanization production line, the present invention realizes the twisting of the rubber sleeve of the cable body 6 at various positions by arranging a first shearing assembly 7 for directional guidance and a second shearing assembly 9 for mobile shearing and a screw assembly in the vulcanization tank 301, and utilizes the shearing action to shear and vulcanize the deep position of the rubber sleeve of the cable body 6, and cooperates with the heat source to vulcanize the surface of the rubber sleeve, thereby improving the vulcanization speed and vulcanization effect.

[0043] See also Figure 3 The vulcanization tank 301 is a horizontal columnar cavity. Inlet holes connected to the vulcanization tank 301 are opened on both sides of the vulcanization box 3. Sealing rings are installed in the inlet holes. A heat source inlet pipe connected to the vulcanization tank 301 is provided on the lower side of the right end of the vulcanization box 3, and a heat source outlet pipe is connected to the upper side of the left end of the vulcanization box 3.

[0044] Specifically, the heat source includes hot air, hot steam and warm water, which is convenient for realizing heating vulcanization, and the vulcanization effect is improved by combining shear vulcanization with heat source heating vulcanization.

[0045] See also Figure 5 and Figure 7 The mounting cylinder 14 is an annular cylinder with a concave cross-section, the rotating cylinder 15 is a closed annular cylinder, the rotating cylinder 15 is rotatably connected to the mounting cylinder 14 through a bearing, the worm ring 18 is installed in an outer annular cavity formed between the mounting cylinder 14 and the rotating cylinder 15, and a mounting cover 17 with a hollow box structure is fixedly connected to the upper end of the mounting cylinder 14. The worm 19 is installed in the outer annular cavity and extends into the mounting cover 17, and the second motor 20 is installed in the mounting cover 17.

[0046] Specifically, the installation cylinder 14, the rotating cylinder 15 and the installation cover 17 are used to realize the sealed assembly of the torsion power component, thereby preventing the heat source from causing damage to the component.

[0047] See also Figure 7-9 The rotating cylinder 15 is provided with an inner annular cavity, the movable frame 1603 is a rectangular frame, the movable frame 1603 penetrates the inner wall of the rotating cylinder 15 and extends into the inner annular cavity, and the radial screw 1604, the passive gear 21, the transmission gear ring 22, the driving gear 23 and the third motor 24 are all installed in the inner annular cavity.

[0048] Specifically, the closed installation of the clamping power component is achieved by the annular rotating cylinder 15.

[0049] See also Figure 6 The clamping wheel 1601 is a guide wheel that is thin in the middle and wide at both ends and has an hourglass-shaped cross section.

[0050] Specifically, while having a good guiding effect, when the cable body 6 needs to be twisted, the clamping wheel 1601 applies a tangential force tangent to the cross-sectional circle of the cable body 6 to the cable body 6, thereby facilitating twisting and shearing.

[0051] Second implementation method:

[0052] Figure 14-15 A vulcanization production line for cable production is shown. Based on the first embodiment, a third shearing assembly 13 is provided on the right side of the second shearing assembly 9, which is symmetrical to the vertical plane of the center of the moving block 10. The structure of the third shearing assembly 13 is the same as that of the second shearing assembly 9. The third shearing assembly 13 and the second shearing assembly 9 have opposite torsional directions when twisting the cable body 6.

[0053] For details, please refer to Fig.15 By providing a third shearing component 13 with opposite torsional directions and synchronous movement with the second shearing component 9, the cable body 6 is locally twisted in opposite directions synchronously, thereby increasing the degree of local misalignment of the rubber sleeve of the cable body 6, improving the shearing effect, and further increasing the shear vulcanization speed and vulcanization effect of the deep layer of the rubber sleeve.

[0054] See also Figure 2 , Figure 5 and Fig. 9 A control terminal 28 is installed on the vulcanization box 3, and the input end of the control terminal 28 is respectively connected to a first photoelectric encoder 25 installed on the output shaft of the first motor 12, a second photoelectric encoder 26 installed on the output shaft of the second motor 20, and a third photoelectric encoder 27 installed on the output shaft of the third motor 24. The first motor 12, the second motor 20 and the third motor 24 are respectively connected to the output end of the control terminal 28.

[0055] Specifically, the number of rotations and the rotation position of the first motor 12 are monitored by the first photoelectric encoder 25, and then the positions of the second shearing assembly 9 and the third shearing assembly 13 are monitored; the number of rotations and the rotation position of the second motor 20 are monitored by the second photoelectric encoder 26, and then the position and the torsion angle of the clamping roller assembly 16 are monitored; the number of rotations and the rotation position of the third motor 24 are monitored by the third photoelectric encoder 27, and then the moving position of the clamping wheel 1601 is monitored, so as to adapt to the clamping, guiding and torsion of the cable body 6 with different diameter specifications.

[0056] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
