Description

Technical Field

[0001] This utility model belongs to the field of roving winding, and specifically relates to a roving winding device. Background Technology

[0002] Currently, roving yarn, also known as carded wool yarn or combed cotton yarn, refers to yarn that is combed using a general spinning system without undergoing a combing process. This type of yarn is mostly used as raw material for general fabrics and knitwear, such as roving wool fabrics and medium- or high-density cotton fabrics. However, when roving yarn is processed, it needs to undergo subsequent combing, de-hairing, and other processes. In order to transfer and store the roving yarn after production, a corresponding winding device is needed to achieve tightening and limiting.

[0003] However, existing winding devices, when in use, generally rely on human visual identification of the current yarn tension when winding the yarn, and cannot achieve automatic identification and adjustment. This can easily lead to unexpected situations such as the roving being too loose or too tight, resulting in yarn breakage. Therefore, they have limitations.

[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking the best, with the assistance of professional knowledge and experience, and after a lot of ingenuity and experimentation, this utility model was created. It provides a roving winding device to solve the problem that the existing devices generally rely on human visual identification of the current tension of the yarn when winding the yarn, which cannot achieve automatic identification and adjustment. This can easily lead to the roving being too loose or too tight, resulting in unexpected situations such as yarn breakage. Utility Model Content

[0005] This utility model proposes a roving winding device, which solves the problem that the existing technology generally relies on human visual identification of the current tension of the yarn when winding it, which cannot achieve automatic identification and adjustment. This can easily lead to the roving being too loose or too tight, resulting in unexpected situations such as yarn breakage.

[0006] The technical solution of this utility model is implemented as follows: a roving winding device includes: a processing mechanism, a horizontally arranged guide rail assembly is fixedly connected to the inner side of the processing mechanism, the guide rail assembly and the processing mechanism together form a guiding structure, and a gantry frame is fixedly connected to the top surface of the guide rail assembly.

[0007] The gantry frame is longitudinally arranged, and a longitudinal groove is opened inside the gantry frame. The bottom end of the transverse component of the gantry frame is fixedly connected to a longitudinally arranged traction push rod. A guide plate is installed at the bottom end of the traction push rod. The guide plate is a rectangular plate structure. A mounting frame is fixedly connected to the bottom surface of the guide plate. The mounting frame is a U-shaped structure with a one-way opening at the bottom. A pressure sensor is fixedly connected to the bottom surface of the transverse component in the mounting frame. An assembly plate is fixedly connected to the bottom end of the pressure sensor. The assembly plate is slidably connected inside the mounting frame. A side plate is fixedly connected to the bottom end of the assembly plate. The side plate is perpendicular to the assembly plate. A guide roller is rotatably connected to the inner side of the side plate. There are two guide rollers. The two guide rollers are arranged in a linear array and rotatably connected to the inner positions of the two side plates. The side plates and guide rollers together form a guiding structure for the yarn.

[0008] In a preferred embodiment, a support leg assembly is fixedly connected to the bottom end face of the processing mechanism. There are four support leg assemblies, which are fixedly connected to the four corners of the bottom end face of the processing mechanism. A guide shaft assembly is fixedly connected to the top end face of the tray assembly. A wire roller is sleeved on the outside of the guide shaft assembly, and a nut is screwed onto the outside of the guide shaft assembly.

[0009] In a preferred embodiment, the processing mechanism is fixedly connected to an installation assembly on its outer side. There are four installation assemblies in total, with each pair of longitudinally adjacent installation assemblies forming a group. A servo motor A is fixedly connected to the outer side of each group of installation assemblies.

[0010] In a preferred embodiment, a drive wheel is mounted on the front output shaft of the servo motor A, and the drive wheel and the servo motor A together form a drive structure.

[0011] In a preferred embodiment, a moving mechanism is slidably connected to the inner side of the guide rail assembly, and two toothed assemblies are fixedly connected to each other on the outer side of the moving mechanism. The toothed assemblies mesh with the drive wheel for transmission.

[0013] After using the above technical solution, the beneficial effects of this utility model are:

[0014] 1. Unlike existing technologies that rely on visual inspection to determine yarn tension, this device uses a pressure sensor to monitor yarn tension in real time and a control system to automatically adjust the speed of the servo motor B, thus achieving automated adjustment of yarn tension. This effectively avoids yarn becoming too loose or too tight due to human visual error, greatly reducing the risk of yarn breakage and improving the quality and efficiency of roving winding.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown, a roving winding device includes: a processing mechanism 1, a transversely arranged guide rail assembly 1014 fixedly connected to the inner side of the processing mechanism 1, the guide rail assembly 1014 and the processing mechanism 1 together form a guiding structure, and a gantry frame 3 fixedly connected to the top surface of the guide rail assembly 1014.

[0026] The gantry frame 3 is arranged longitudinally, and a longitudinal groove is opened inside the gantry frame 3. The bottom end of the transverse component in the gantry frame 3 is fixedly connected to a longitudinally arranged traction push rod 301. A guide plate 3011 is installed at the bottom end of the traction push rod 301. The guide plate 3011 is a rectangular plate structure. A mounting frame 3012 is fixedly connected to the bottom surface of the guide plate 3011. The mounting frame 3012 is a U-shaped structure with a one-way opening at the bottom end. A pressure sensor 3013 is fixedly connected to the bottom surface of the transverse component in the mounting frame 3012. An assembly plate 3014 is fixedly connected to the bottom end of the pressure sensor 3013. The assembly plate 3014 is slidably connected in the mounting frame 3012. A side plate 3015 is fixedly connected to the bottom end of the assembly plate 3014. The side plate 3015 is perpendicular to the assembly plate 3014. The inner side of the moving mechanism 5 is rotatably connected to a guide roller 3016. There are two guide rollers 3016 in total. The two guide rollers 3016 are rotatably connected to the inner side of two side plates 3015 in a linear array. The side plates 3015 and the guide rollers 3016 together form a guiding structure for the yarn. The outer side of the moving mechanism 2 is fixedly connected to two slider assemblies 2011 with protruding structures. The bottom end of the moving mechanism 2 is fixedly connected to a base plate 2012. The bottom end of the base plate 2012 is equipped with a servo motor B2013. The top output shaft of the servo motor B2013 is equipped with a tray assembly 2014. The top end of the tray assembly 2014 is fixedly connected to a guide shaft assembly 2015. The outer side of the guide shaft assembly 2015 is sleeved with a yarn roller 2017. The outer side of the guide shaft assembly 2015 is screwed with a nut 2016.

[0027] Among them, a support assembly 101 is fixedly connected to the bottom end face of the processing mechanism 1. There are four support assemblies 101 in total, and the four support assemblies 101 are fixedly connected to the four corners of the bottom end face of the processing mechanism 1. An installation assembly 1011 is fixedly connected to the outside of the processing mechanism 1. There are four installation assemblies 1011 in total, and each pair of longitudinally adjacent installation assemblies 1011 forms a group. A servo motor A1012 is fixedly connected to the outside of each group of installation assemblies 1011.

[0028] Among them, a drive wheel 1013 is installed on the front output shaft of the servo motor A1012. The drive wheel 1013 and the servo motor A1012 together form a drive structure. A moving mechanism 2 is slidably connected to the inner side of the guide rail assembly 1014. Two gear rack assemblies 201 are fixedly connected to the outer side of the moving mechanism 2 in opposite directions. The gear rack assembly 201 meshes with the drive wheel 1013 for transmission.

[0029] In use, place one end of the roving to be wound under the guide roller 3016, so that the yarn maintains a certain direction under the guidance structure composed of the side plate 3015 and the guide roller 3016. The yarn roller 2017 is installed on the guide shaft assembly 2015 and fixed by the nut 2016 to ensure that the yarn roller 2017 is installed firmly and can rotate smoothly, in preparation for subsequent yarn winding.

[0030] When the servo motor A1012 is started, its front output shaft drives the drive wheel 1013 to rotate. Since the gear assembly 201 meshes with the drive wheel 1013 and the gear assembly 201 is fixed on the outside of the moving mechanism 2, the rotation of the drive wheel 1013 will drive the moving mechanism 2 to slide along the guide rail assembly 1014. The slider assembly 2011 on the outside of the moving mechanism 2 cooperates with the guide rail assembly 1014 to ensure the stability and smoothness of the movement of the moving mechanism 2.

[0031] After the moving mechanism 2 moves to the appropriate position, the servo motor B2013 is started. Its top output shaft drives the tray assembly 2014 to rotate, which in turn drives the yarn roller 2017 to rotate. As the yarn roller 2017 rotates, the yarn begins to be wound on the yarn roller 2017. During the winding process, the traction push rod 301 at the bottom of the transverse component in the gantry 3 can be extended or shortened according to actual needs. This needs are adjusted according to the different winding height of the roving. For example, when winding from the bottom of the yarn roller 2017, the traction push rod 301 is started to drive the guide plate 3011, mounting frame 3012, pressure sensor 3013, assembly plate 3014, side plate 3015 and guide roller 3016 to move up and down as a whole, thereby adjusting the winding position of the yarn so that the yarn is evenly wound on the yarn roller 2017.

[0032] During the yarn winding process, the pressure sensor 3013 monitors the yarn tension in real time. When the yarn is too loose, the pressure detected by the pressure sensor 3013 decreases. At this time, the control system can control the servo motor B2013 to increase its speed, so that the yarn roller 2017 winds the yarn faster, thereby tightening the yarn. When the yarn is too tight, the pressure detected by the pressure sensor 3013 increases. The control system controls the servo motor B2013 to decrease its speed, slowing down the yarn winding speed and preventing the yarn from breaking. Through this automated monitoring and adjustment method, the yarn is always kept in a suitable tension.

[0033] In practical applications, a pressure sensor 3013 with an accuracy of 0.1N and a measurement range of 0-10N can be selected, which can meet the requirements for accurate measurement of yarn tension during roving winding. Simultaneously, it is specified that analog signal transmission is used between the pressure sensor 3013 and the control system. An A / D conversion module converts the analog signal into a digital signal for processing by the control system. The pressure sensor 3013 is connected to the input port of the control system via a signal line to ensure the stability of signal transmission. Based on the signal fed back from the pressure sensor 3013, the control system controls the speed of the servo motor B2013 via a control cable. To ensure the accuracy and stability of control, a programmable logic controller (PLC) is used in the control system, and a corresponding control program is written to achieve precise control of the speed of the servo motor B2013.
