When the paid-out cable is larger than the collected / transported cable, the cable tends to be loose. When the paid-out cable is smaller than the collected / transported cable, the cable tends to be tighter. This also leads to the following problems: the sprayed color ring is not uniform enough; when replacing the pay-off reel on the take-up shaft, the entire production line needs to be stopped.

[0019] The following is further explained in conjunction with the accompanying drawings. Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] See also Figure 1 and Figure 2 A cable retracting and releasing adjustment mechanism comprises a frame body 1, a mounting portion 2, two wire wheels 3 and an action portion 4.

[0021] The mounting portion 2 is movably connected to the frame body 1. More specifically, the movably connected between the mounting portion 2 and the frame body 1 is a hinged connection or a sliding connection.

[0022] One of the two wire wheels 3 is rotatably connected to the frame 1, that is, the wire wheel 3 is relatively fixed; the other is rotatably connected to the mounting portion 2, that is, the wire wheel 3 is relatively movable. The distance between the two wire wheels 3 can be increased or decreased by the movement of the mounting portion 2 relative to the frame 1. The mounting portion 2 and the frame 1 are hinged, and the range of the distance between the two wire wheels 3 can be relatively small; the mounting portion 2 and the frame 1 are slidably connected, and the range of the distance between the two wire wheels 3 can be relatively larger.

[0023] The action part 4 acts on the mounting part 2 to increase the distance between the two guide wheels 3. For example, the action part 4 can be an elastic member disposed between the mounting part 2 and the frame 1.

[0024] In some embodiments, the movable connection between the mounting portion 2 and the frame 1 can adopt the above-mentioned hinge connection, but the axis of rotation needs to be limited to be horizontal; it can also adopt the above-mentioned sliding connection, but the sliding direction needs to be limited to the up and down direction. Accordingly, after the above-mentioned further limitations are added to the hinge connection and the sliding connection, the two wire wheels 3 need to be arranged one above and one below.

[0025] Thus, the acting part 4 may be an elastic member or a counterweight, and gravity may be used to act on the mounting part 2, so that the mounting part 2 swings or slides in a direction that increases the distance between the two guide wheels 3 .

[0026] Furthermore, the action part 4 is a first counterweight block, that is, a counterweight is used to move the mounting part 2. Compared with the use of elastic members, the structure is simpler, and the gravity acting on the mounting part 2 remains unchanged during the movement of the mounting part 2.

[0027] See also Figure 1 In some embodiments (marked as embodiment 1), on the basis of the above-mentioned "the action part 4 is the first counterweight block", for the two wire wheels 3, the wire wheel 3 connected to the mounting part 2 is at the bottom. The first counterweight block is the mounting part 2 itself. That is, by using the gravity of the mounting part 2 itself, the mounting part 2 can be swung or slid in the direction of increasing the distance between the two wire wheels 3.

[0028] See also Figure 2 In some implementations (marked as Example 2), on the basis of the above-mentioned "the action part 4 is the first counterweight", for the two wire pulleys 3, the wire pulley 3 connected to the mounting part 2 is on the top, and a connecting link is provided between the first counterweight and the mounting part 2, and the connecting link can be a belt, a chain, etc. The frame 1 is provided with a fixed pulley 1a that acts on the connecting link and changes the direction of the force, and the fixed pulley 1a can be a pulley, a sprocket 11a, etc. That is, the direction of the force is changed by the fixed pulley 1a, so that the first counterweight slides downward, driving the mounting part 2 to move upward. In addition, in this implementation, it is more appropriate for the mounting part 2 to slide up and down compared to the hinge.

[0029] The two wire wheels 3 are both provided with a plurality of wire grooves for allowing the cable to be wound multiple times, so that the distance between the two wire wheels 3 tends to be reduced, and the force of the action part 4 on the mounting part 2 is balanced.

[0030] More specifically, the mounting portion 2 is designed with two limit positions, the first limit position corresponds to a maximum distance between the two wire wheels 3 , and the second limit position corresponds to a minimum distance between the two wire wheels 3 .

[0031] When no cable is wound between the two wire wheels 3, "the acting portion 4 acts on the mounting portion 2 to increase the distance between the first wire wheel 3 and the second wire", that is, at this time, the acting portion 4 makes the mounting portion 2 in the first limit position.

[0032] The cable enters the cable retracting and releasing adjustment mechanism, and after being wound multiple times on the two wire wheels 3 and leaving, the cable between the two wire wheels 3 is straightened, "for winding the cable multiple times so that the distance between the two wire wheels 3 tends to decrease", that is, the tension of the cable acts on the two wire wheels 3, so that the mounting portion 2 is in a position between the first limit and the second limit.

[0033] "Balancing the force of the action part 4 on the installation part 2" means that the force on the installation part 2 is balanced. In the two side positions of the cable retracting and releasing adjustment mechanism, one side is a device that actively releases the cable; the other side is a device that actively collects / transports the cable. In theory, the released cable and the collected / transported cable are synchronized, and the installation part 2 will also maintain the initial position between the first limit and the second limit. In fact, the released cable and the collected / transported cable will each fluctuate due to various reasons. When the released cable is larger than the collected / transported cable, the cable between the two wire wheels 3 tends to relax, and the action part 4 causes the installation part 2 to move toward the first limit, the spacing between the first wire wheel 3 and the second wire increases, and the balance is restored on the installation part 2. When the released cable is smaller than the collected / transported cable, the cable between the two wire wheels 3 tends to be tighter, causing the installation part 2 to move toward the second limit, the spacing between the first wire wheel 3 and the second wire decreases, and the balance is restored on the installation part 2.

[0034] See also Figure 3 A cable color ring production line includes a pay-off shaft 5, a synchronous tension wheel 6, a color ring synchronizer 7, a color ring inkjet printer 8, a drying device 9, a traction device 10, a wire storage device 11 and a take-up shaft 12.

[0035] See also Figure 3 and Figure 4 The pay-off shaft 5 is used for installing a pay-off drum with a cable wound thereon. After the cable on the pay-off drum is led out, the first motor 5a drives the installed pay-off drum to rotate, thereby releasing the cable on the pay-off drum.

[0036] See also Figure 4 , Figure 5 and Figure 6 , the synchronous tension wheel 6 includes the above-mentioned cable retracting and releasing adjustment mechanism and the sensor 6a.

[0037] The cable retracting and releasing adjustment mechanism in the synchronous tension wheel 6 is arranged in accordance with the above-mentioned embodiment 1, satisfying the following conditions: the movable connection between the mounting part 2 and the frame 1 is a hinged connection around a horizontal axis or an up and down sliding connection; the action part 4 is a first counterweight block; for the two wire wheels 3, the wire wheel 3 connected to the mounting part 2 is at the bottom, and the first counterweight block is the mounting part 2 itself.

[0038] The sensor 6a controls the first motor 5a of the synchronous tension wheel 6 through the mounting part 2. That is, the position change of the mounting part 2 is reflected to the sensor 6a, and then the first motor 5a is controlled. More specifically, a PLC can be used, the PLC is connected to an analog module, the sensor 6a is input to the analog module, the analog module outputs data according to a linear relationship and stores it in the PLC, and the PLC edits a corresponding program to control the first motor 5a to form feedback regulation.

[0039] When the cable released by the pay-off shaft 5 is less than the cable transported by the subsequent color ring synchronizer 7, the mounting part 2 is active, the distance between the two synchronous wheels is reduced, and the value input to the analog module by the sensor 6a increases or decreases. After exceeding the range set in the PLC program, the PLC accelerates the first motor 5a to increase the cable released by the pay-off shaft 5. On the contrary, when the cable released by the pay-off shaft 5 is more than the cable transported by the subsequent color ring synchronizer 7, the mounting part 2 is active, the distance between the two synchronous wheels is increased, and the value input to the analog module by the sensor 6a increases or decreases. After exceeding the range set in the PLC program, the PLC decelerates the first motor 5a to reduce the cable released by the pay-off shaft 5.

[0040] See also Figure 6 In some embodiments, for the cable retracting and releasing adjustment mechanism in the synchronous tension wheel 6, the movable connection between the mounting portion 2 and the frame 1 is a hinge, and the mounting portion 2 is also fixedly connected at the hinge position with an eccentric wheel 6b for sensing by the sensor 6a.

[0041] Compared with sliding up and down, the eccentric wheel 6b is hingedly matched. When the mounting part 2 swings, the amount of change of the eccentric wheel 6b in the vertical direction is relatively small, which is more suitable for being sensed by the sensor 6a, for example, a capacitive sensor 6a can be used. By designing the length of the mounting part 2, the spacing between the two guide wheels 3 can still be within a certain appropriate range through the swing of the mounting part 2.

[0042] See also Figure 5 In some embodiments, for the cable retraction and release adjustment mechanism in the synchronous tension wheel 6, a second counterweight block 6c is also fixedly connected to the mounting portion 2, and the second counterweight block 6c can be adjusted to a fixed position on the mounting portion 2, away from or close to the hinge position.

[0043] The tension of the cable between the two guide wheels 3 can be adjusted by adjusting the second counterweight 6c. That is, when the second counterweight 6c is away from the hinged position, the moment on the mounting portion 2 increases, and accordingly, in order to maintain the balance of the mounting portion 2, the tension on the cable also increases; when the second counterweight 6c is close to the hinged position, the moment on the mounting portion 2 decreases, and accordingly, in order to maintain the balance of the mounting portion 2, the tension on the cable also decreases.

[0044] See also Figure 5In some embodiments, the synchronous tension wheel 6 further includes a normally closed travel switch 6d. The normally closed travel switch is arranged on the frame 1, below the corresponding mounting portion 2 and is triggered by the mounting portion 2, and is used to control the cable color ring production line. That is, when the mounting portion 2 does not contact the normally closed travel switch 6d, the normally closed travel switch 6d is turned on, and the operation of the cable color ring production line is not affected; when an unexpected situation occurs, such as the cable is disconnected or detached from the wire wheel 3, the mounting portion 2 is pressed downward to the normally closed travel, which is triggered, and the cable color ring production line is suspended.

[0045] See also Figure 3 and Figure 4 The color ring synchronizer 7 is used to transmit the cable coming out of the synchronous tension wheel 6. More specifically, the color ring synchronizer 7 includes a first traction wheel 7a, a second motor driving the first traction wheel 7a to rotate, and first guide wheels 7b arranged on both sides of the first traction wheel 7a. The two first guide wheels 7b are used to increase the contact area between the cable and the first traction wheel 7a. Through friction, the first traction wheel 7a rotates to transport the cable. When the first traction wheel 7a stops rotating and does not transport the cable, the cable can be fixed on the first traction wheel 7a and the two first guide wheels 7b through friction. The two first guide wheels 7b can also adjust their positions up and down relative to the first traction wheel 7a to adjust the contact area between the cable and the first traction wheel 7a.

[0046] See also Figure 3 The coding of the color ring inkjet printer is controlled by the color ring synchronizer 7. More specifically, every time the first traction wheel 7a of the color ring synchronizer 7 rotates a certain angle, the color ring inkjet printer will code the cable once.

[0047] See also Figure 3 The drying device 9 is used to dry the color ring sprayed on the surface of the cable. More specifically, the drying device 9 may include a pipe 9a for the cable to pass through and a warm air blower 9b connected to the pipe 9a. In addition, a blower 9c may be provided outside the drying device 9 to blow air and cool the cable coming out of the drying device 9. See also Figure 7 The traction device 10 is used to convey the cable from the drying device 9. More specifically, the traction device 10 is a belt conveyor type, that is, the cable passes between the second traction wheel 10a and the conveyor belt 10b and is conveyed by friction. In addition, the traction device 10 can be equipped with an encoder to record the number of meters of the cable passing through.

[0048] See also Figure 7 and Figure 8 The cable storage device 11 includes the above-mentioned cable retracting and releasing adjustment mechanism.

[0049] The cable retracting and releasing adjustment mechanism in the wire storage device 11 is arranged in accordance with the above-mentioned second embodiment, satisfying the following requirements: the movable connection between the mounting part 2 and the frame body 1 is an up and down sliding connection; the acting part 4 is a first counterweight block; for the two wire wheels 3, the wire wheels 3 connected to the mounting part 2 are at the top, a connecting link is arranged between the first counterweight block and the mounting part 2, and a fixed pulley 1a is arranged on the frame body 1, which acts on the connecting link and changes the direction of the force.

[0050] By adopting the up and down sliding and designing the wire wheel 3 connected to the mounting part 2 at the top, the range of movement between the two wire wheels 3 is larger, which is more in line with the requirements of the wire storage device 11 for the amount of stored cables and the safety requirements of the wire storage device 11 during use.

[0051] In addition, the first counterweight block is adjusted, and weight blocks of different weights are installed as the first counterweight block, so that the tension of the cable between the two wire wheels 3 can be adjusted.

[0052] See also Figure 8 In some embodiments, the wire storage device 11 further includes a fifth motor 11b and a brake 11c. The connecting link is a closed chain, that is, the frame 1 is also equipped with an upper and lower sprocket 11a, and the fixed pulley 1a is the upper sprocket 11a. The fifth motor 11b is connected to the lower sprocket 11a, and the brake 11c is used to suspend the corresponding mounting part 2, that is, when the fifth motor 11b and the brake 11c are not started, the first counterweight block can drive the mounting part 2 to slide upward through the chain.

[0053] When winding the cable between the two wire wheels 3, the fifth motor 11b can be used to first move the mounting part 2 downward by a certain distance so that the mounting part 2 is between the two designed limit positions, and the brake 11c is used to lock the rotation of the lower sprocket 11a so that the mounting part 2 remains in this position, i.e., it is suspended. After the cable winding between the two wire wheels 3 is completed, the fifth motor 11b and the brake 11c are turned off, the mounting part 2 tends to move upward, and the tension between the first counterweight block and the cable finally balances the mounting part 2.

[0054] When the cable delivered by the traction device 10 is less than the cable collected by the subsequent take-up shaft 12, the installation part 2 moves and the distance between the two synchronous wheels decreases. Conversely, when the cable delivered by the traction device 10 is more than the cable collected by the subsequent take-up shaft 12, the installation part 2 moves and the distance between the two synchronous wheels increases.

[0055] See also Figure 7The wire take-up shaft 12 collects the cables coming out of the wire storage mechanism. The wire take-up shaft 12 is used to connect the cables coming out of the wire storage device 11. The fourth motor 12a drives the wire pay-off drum to rotate, thereby collecting the cables. In addition, in order to make the cables swing back and forth along the axis of the wire pay-off drum during the process of being collected by the wire pay-off drum, the wire take-up shaft 12 also includes a wire module 12b for guiding the cables and a screw module 12c for driving the wire module 12b to slide back and forth.

[0056] When replacing the pay-off reel on the take-up reel 12, only the take-up reel 12 is paused, the broken end of the cable is fixed, the new pay-off reel is installed on the take-up reel 12, the broken end of the cable is connected to the new pay-off reel, and the take-up reel 12 is started. There is no need to stop the parts between the pay-off reel 5 and the wire storage device 11. The wire sent out by the traction device 10 will be stored between the two synchronous wheels through the increase of the spacing between the two synchronous wheels. When starting the take-up reel 12, the speed of the take-up reel 12 is first adjusted faster to collect more cables stored between the two synchronous wheels. After the spacing between the two synchronous wheels is reduced to return to the original appropriate range, the speed of the take-up reel 12 is adjusted back.
