[0027] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessary ambiguity in the present application; and, for clarity, the sizes of some structures may be exaggerated.

[0030] Under existing technology, the seven-roller mill's startup and speed-up process is time-sensitive, and manual operation by workers is prone to operational errors, resulting in production losses. Furthermore, when a large number of production lines need to be started, personnel spend a long time on the mill, unable to start operations in a timely manner, resulting in wasted waiting time.

[0031] This application solves the problem of automating the start-up and speed-up of the seven-roller machine during the process of double-drawing start-up and speed-up, and reduces the problem of easy mistakes in human operation. Figure 1 and Figure 2 The multiple wire pulling assembly of the embodiment of the present application is described in detail.

[0032] Figure 1 This is a structural diagram of a multiple wire pulling assembly provided in an embodiment of the present application. Figure 2 for Figure 1 A partial enlarged view of .

[0033] See also Figure 1 The embodiment of the first aspect of the present application provides a multiple-thread drawing assembly for producing fiber 000, comprising a traction mechanism 100, a baking mechanism 200, a first rotating mechanism 300, and a button controller 500. The traction mechanism 100 comprises a traction rope 110, which is used to draw fiber 000. The traction rope 110 comprises a traction portion 120, which is connected to fiber 000 and is located on the downstream side of the traction rope 110. The baking mechanism 200 is used to bake the fiber 000. The first rotating mechanism 300 is located downstream of the baking mechanism 200 and is used to drive the traction rope 110. The button controller 500 is used to control the first rotating mechanism 300 to accelerate its rotation when the traction portion 120 is drawn and passes downstream of the first rotating mechanism 300.

[0034] In the embodiment provided herein, the multiple-thread assembly includes a traction mechanism 100, a baking mechanism 200, a first rotating mechanism 300, and a button controller 500. The traction mechanism 100 includes a traction rope 110, which is used to pull the fiber 000. The traction rope 110 includes a traction portion 120, which is connected to the fiber 000 and located downstream of the traction rope 110. The baking mechanism 200 is used to heat and bake the fiber 000. The first rotating mechanism 300 is located downstream of the baking mechanism 200 and is used to drive the traction rope 110. When the button controller 500 is activated, when the traction portion 120 is pulled downstream of the first rotating mechanism 300, the button controller 500 controls the first rotating mechanism 300 to accelerate. The first rotating mechanism 300 drives the fiber 000 at a higher speed, creating a speed difference with the original fiber 000 movement speed, thereby stretching the fiber 000. In the embodiment of the present application, by setting a button controller 500, the first rotating mechanism 300 can be automatically accelerated when the traction part 120 is pulled to pass downstream of the first rotating mechanism 300, without manual operation, thereby improving production efficiency and production automation.

[0035] Optionally, the fiber 000 to be processed is an ultra-high molecular weight polyethylene fiber, and the baking mechanism 200 bakes and utilizes the speed difference to stretch the fiber as one of the process steps for producing the fiber 000. The produced ultra-high molecular weight polyethylene fiber can generally be used to make ropes and fishing nets, and can also be used for textiles, bulletproofing, breeding, etc.

[0036] Optionally, the baking mechanism 200 may be an oven, and the fiber 000 may be subjected to a high-temperature baking and stretching process in the oven.

[0037] Alternatively, the traction rope 110 may be an aramid rope, which has a low stretchability. In this embodiment, the first rotating mechanism 300 automatically accelerates only after the traction unit 120 has been pulled downstream of the first rotating mechanism 300. At this point, only the fibers 000 are stretched, thereby alleviating the problem of aramid rope breakage caused by stretching. The material of the traction rope 110 is not specifically limited, as long as it is heat-resistant and corrosion-resistant and meets manufacturing requirements.

[0038] Optionally, the traction portion 120 is the connection between the traction rope 110 and the fiber 000 , and the traction portion 120 is located downstream of the fiber 000 .

[0039] Optionally, when all accelerations are completed, the first rotating mechanism 300 will not continue to accelerate by pressing the button controller 500. That is, the button controller 500 can be used to control the start, stop and acceleration state of the first rotating mechanism 300.

[0040] In some optional embodiments, the multiple thread pulling assembly further includes a second rotating mechanism 400 and a timer. The second rotating mechanism 400 is located upstream of the baking mechanism 200 and is configured to move the fiber 000 at a first constant speed V1. The timer is configured to measure the rotation time t1 of the second rotating mechanism 400. The maximum distance between the first rotating mechanism 300 and the second rotating mechanism 400 is L1. The button controller 500 is configured to accelerate the first rotating mechanism 300 when L1 = V1t1.

[0041] In these optional embodiments, the button controller 500 is used to control the automatic acceleration of the first rotating mechanism 300 when L1 = V1t1, that is, after the position of the traction portion 120 passes the downstream of the first rotating mechanism 300 through automatic calculation.

[0042] For example, when the operator presses the button controller 500, the second rotating mechanism 400 starts to drive the fiber 000 to move at a constant speed of the first speed V1, and the timer starts to accumulate the rotation time t1 of the second rotating mechanism 400. The product of the first speed V1 and the rotation time t1 of the second rotating mechanism 400 is the distance moved by the traction part 120. When the distance moved by the traction part 120 is the maximum distance L1 between the first rotating mechanism 300 and the second rotating mechanism 400, it can be determined that the traction part 120 has just passed the downstream end of the first rotating mechanism 300. At this time, the button controller 500 can be used to control the first rotating mechanism 300 to start accelerating.

[0043] Afterwards, due to the accelerated operation of the first rotating mechanism 300, the rotation speed of the first rotating mechanism 300 is greater than the rotation speed of the second rotating mechanism 400, so that the fiber 000 can be stretched in the baking mechanism 200, and the automatic acceleration of the first rotating mechanism 300 can be achieved through the button controller 500 and the timer. No manpower is required, and the position of the traction part 120 is automatically obtained through calculation, the acceleration timing is accurate, and the production efficiency is improved at the same time.

[0044] Optionally, the first rotating mechanism 300 and the second rotating mechanism 400 may both be seven-roller machines, and the rollers of the seven-roller machine drive the fiber 000 to move, thereby achieving stretching of the fiber 000.

[0045] In some optional embodiments, the multiple-pull assembly further includes two or more first rotating mechanisms 300, and a baking mechanism 200 is provided between two adjacent first rotating mechanisms 300. The button controller 500 is used to control at least one first rotating mechanism 300 to accelerate rotation when the traction part 100 passes downstream of at least one first rotating mechanism 300.

[0046] In these optional embodiments, when the traction part 120 passes downstream of at least one first rotating mechanism 300, the button controller 500 can control at least one first rotating mechanism 300 to accelerate rotation, thereby realizing step-by-step automatic acceleration between multiple first rotating mechanisms 300, and improving the situation where the multiple first rotating mechanisms 300 accelerate too fast or too slow, causing wire breakage or damage to the equipment.

[0047] Optionally, when the traction part 120 reaches any first rotating mechanism 300, the button controller 500 can control all the first rotating mechanisms 300 that the traction part 120 has not passed through to accelerate their rotation, thereby realizing step-by-step automatic acceleration between any first rotating mechanism 300 that the traction part 120 has passed through and the first rotating mechanism 300 that the traction part 120 has not passed through, thereby improving the situation where the multiple first rotating mechanisms 300 accelerate too fast or too slow, causing wire breakage or damage to the equipment.

[0048] Optionally, the timer can also be used to determine the time t2 at which the first rotating mechanism 300 upstream of the multiple-wire assembly begins accelerating. The maximum distance between the multiple first rotating mechanisms 300 is L2. The button controller 500 is used to determine the position of the traction unit 120 by using L2-t2(V1+V2) / 2, thereby controlling the acceleration of all first rotating mechanisms 300 that the traction unit 120 has not passed. For example, there may be three first rotating mechanisms 300, and the second rotating mechanism 400 may rotate at a uniform speed of first velocity V1. When the traction unit 120 is pulled past the first first rotating mechanism 300, all first rotating mechanisms 300 are accelerated to rotate at V2. The button controller 500 can determine the position of the traction unit 120 by using L2-t2(V1+V2) / 2. When the traction unit 120 is pulled past the second first rotating mechanism 300, while the first first rotating mechanism 300 is still rotating at V2, the first rotating mechanism 300 controls the second and third first rotating mechanisms 300 to automatically accelerate to rotate at V3. When the traction unit 120 is pulled through the third first rotating mechanism 300, the first first rotating mechanism 300 rotates at V2, the second first rotating mechanism 300 rotates at V3, and the third first rotating mechanism 300 rotates at V4, where V1 is the initial acceleration speed and V4 is the final acceleration speed of the first rotating mechanism 300. This embodiment of the present application can achieve step-by-step automatic acceleration of multiple first rotating mechanisms 300, thereby alleviating the problem of wire breakage or equipment damage caused by excessive or slow acceleration of multiple first rotating mechanisms 300.

[0049] In some optional embodiments, the multiple-wire assembly further includes an indicator light 510, which is used to display the acceleration state of the first rotating mechanism 300. The color of the indicator light 510 when the first rotating mechanism 300 is in the acceleration state is different from the color of the indicator light 510 when the acceleration is completed.

[0050] In these optional embodiments, the multiple-pull assembly also includes an indicator light 510. The color of the indicator light 510 when the first rotating mechanism 300 is in the acceleration state is different from the color of the indicator light 510 when the acceleration is completed. For example, when the first rotating mechanism 300 is in the acceleration process, it displays red, and when the first rotating mechanism 300 is accelerated into place, the indicator light 510 displays green, which makes it convenient for staff to monitor the working conditions of the production line.

[0051] Optionally, the position of the indicator light 510 is not specifically limited, as long as it is convenient for staff to observe. Specifically, the indicator light 510 can be set on any first rotating mechanism 300 to more intuitively display the acceleration state of the first rotating mechanism 300.

[0052] In some optional embodiments, the multiple-wire assembly further includes a warning light 520 , which is used to issue an alarm when an abnormality occurs in the production process.

[0053] In these optional embodiments, the warning light 520 is used to alarm when an abnormality occurs in the production process. For example, when the first rotating mechanism 300 and the second rotating mechanism 400 stop suddenly, or when the inverter of the oven mechanism fails, the flashing of the warning light 520 can alert the staff to stop the machine for inspection.

[0054] In some optional embodiments, the first rotating mechanism 300 and / or the second rotating mechanism 400 includes a roller assembly 310, and the roller assembly 310 includes rollers 313 arranged at intervals along the first direction X. The rollers 313 are used to wind the traction rope 110, and the traction rope 110 is driven to move by the rotation of the rollers 313.

[0055] In these optional embodiments, the roller assembly 310 includes rollers 313 spaced apart along the first direction X. The rollers 313 are used to wind the traction rope 110. The rotation of the rollers 313 drives the traction rope 110 to move. By changing the rotation speed of the rollers 313, the movement and stretching of the fiber 000 can be achieved.

[0056] In some optional embodiments, the roller assembly 310 includes a first roller assembly 311 and a second roller assembly 312 . The roller assemblies 310 are spaced apart along the second direction, and the number of rollers 313 in the first roller assembly 311 is less than the number of rollers 313 in the second roller assembly 312 .

[0057] In these optional embodiments, the fiber 000 is sequentially wound between the roller 313 of the second roller assembly 312 and the roller 313 of the first roller assembly 311 along the moving direction, which can improve the problem of winding of the fiber 000 during movement.

[0058] In some optional embodiments, the roller 313 of the first roller assembly 311 is located between adjacent rollers 313 of the second roller assembly 312 along the second direction, and the fiber 000 is wound sequentially between the roller 313 of the second roller assembly 312 and the roller 313 of the first roller assembly 311 along the direction of movement.

[0059] In these optional embodiments, the roller 313 of the first roller assembly 311 is located between the adjacent rollers 313 of the second roller assembly 312 along the second direction, and the fiber 000 is wound sequentially between the roller 313 of the second roller assembly 312 and the roller 313 of the first roller assembly 311 along the direction of movement, which can improve the problem of winding of the fiber 000 during movement.

[0060] In some optional embodiments, the traction mechanism 100 further includes an unwinder 130 , on which the fiber 000 is wound. The unwinder 130 is located upstream of the re-drawing assembly and is used to output the fiber 000 to be processed.

[0061] In these optional embodiments, the unwinder 130 is located upstream of the re-drawing assembly. The unwinder 130 is used to receive and output the fiber 000 to be processed. The fiber 000 moves driven by the first rotating mechanism 300 and the second rotating mechanism 400, and is unwound from the unwinder 130 at the same time to complete the baking and stretching.

[0062] Alternatively, the unwinder 130 may not need to provide power for unwinding the fiber 000, and the fiber 000 may be driven by the first rotating mechanism 300 and the second rotating mechanism 400 to move and unwind, thereby saving energy. Alternatively, the unwinder 130 may provide power for unwinding the fiber 000, and the fiber 000 may be unwound by the unwinder 130, the first rotating mechanism 300, and the second rotating mechanism 400.

[0063] In some optional embodiments, the traction mechanism 100 further includes a winder 140, which is located downstream of the re-drawing assembly and is used to receive the processed fiber 000. Optionally, the winder 140 needs to provide its own power for unwinding the fiber 000.

[0064] In these optional embodiments, the winder 140 is located downstream of the re-drawing assembly and is used to receive the processed fiber 000. Optionally, the winder 140 can provide its own power for winding the fiber 000 to store and store the processed fiber 000, thereby improving the problem of fiber 000 winding and knotting.

[0065] Optionally, one end of the traction rope 110 is connected to the fiber 000, and the other end is connected to the winding machine 140 to pull the fiber 000 to move.

[0066] Optionally, the multiple wiring assembly further includes a central control device, which is used to display the operating status of the first rotating mechanism 300, the second rotating mechanism 400 and the baking mechanism 200. For example, the central control device can display whether the first rotating mechanism 300 and the baking mechanism 200 are started.

[0067] Optionally, the central control device also includes a temperature indication, which is used to prompt when the temperature of the baking mechanism 200 reaches a preset temperature, so that the staff can operate the first rotating mechanism 300 and the second rotating mechanism 400 according to the temperature indication to improve the baking mechanism 200. The temperature is too high and does not meet the process requirements.

[0068] Optionally, the central control device can also display the current operating specifications of the production line, so that the staff can make timely adjustments based on the on-site conditions.

[0069] Optionally, the central control device can also limit the number of times the first rotating mechanism 300 accelerates, so as to improve the problem of fiber 000 breaking or equipment damage caused by accelerating too fast or too slow during the first rotating mechanism 300 acceleration process.

[0070] Optionally, the central control device includes an account that can only be operated by the administrator, which can realize the start and stop of the multiple wiring assembly and the acceleration and deceleration of the first rotating mechanism 300. When the administrator logs out, the staff can only view the instructions of the central control device and cannot operate.

[0071] Optionally, the first rotating mechanism 300 and the second rotating mechanism 400 may be seven-roller machines, there may be four seven-roller machines, there may be two baking assemblies, and two baking assemblies are provided between the two seven-roller machines.

[0073] After the staff member confirms via the central control device that the baking mechanism 200 has reached the preset temperature, a matrix of product specifications and speeds is displayed on the central control device. The staff member can select the corresponding product specifications and the final speed of the No. 4 seven-roller mill 004, starting all seven-rollers and ensuring that all seven-rollers are running at a uniform speed. The staff member then presses the button controller 500. When the traction unit 120 passes the downstream end of the No. 2 seven-roller mill 002, the No. 2 seven-roller mill 002, the No. 3 seven-roller mill 003, and the No. 4 seven-roller mill 004 all automatically accelerate. When the traction unit 120 passes the downstream end of the No. 3 seven-roller mill 003, the No. 3 seven-roller mill 003 and the No. 4 seven-roller mill 004 all automatically accelerate. When the traction unit 120 passes the downstream end of the No. 4 seven-roller mill 004, the No. 4 seven-roller mill 004 automatically accelerates, completing the acceleration of all seven-roller mills, thus achieving automated production of multi-wire assembly.
