Description

Technical Field

[0001] This utility model relates to a ring spinning machine for textiles. More specifically, this utility model relates to the spindle arrangement of a ring spinning machine for textiles. Background Technology

[0002] In textile spinning mills, cotton is transformed into yarn through a series of machines. The ring spinning machine is a key machine in textile spinning mills for producing synthetic yarn. Textile roving material produced by the roving frame is typically fed into the ring spinning machine. The ring spinning machine is the final stage of cotton feeding in the spinning process, the so-called yarn. The fed roving material is drafted by means of a drafting device. Furthermore, the drafted fibers are spun into yarn by means of a ring and traveler arrangement. The spun yarn is further wound onto bobbins placed on spindles. Ring spinning machines are typically divided into multiple sections along the length of a frame approximately 75 meters long, arranged in two rows. The spinning machine typically consists of two rows of up to 1824 spindles (i.e., 912 spindles per row). In existing ring spinning machines, the center-to-center pitch / gauge length between adjacent spindles is 70 mm or greater.

[0003] In existing ring spinning machines, the increased space between adjacent spindles requires increased raw material consumption for related components during manufacturing, leading to higher costs. Existing ring spinning machines also occupy a significant floor space in textile mills after installation, resulting in higher capital and recurring costs. Due to the modern demands of the textile industry, it is necessary to optimize the production of ring spinning machines within existing spaces. This necessitates the development of new spindle arrangements that optimize the output of ring spinning machines with existing layouts.

[0004] There is a need to overcome the above-mentioned shortcomings, and this invention provides an improved solution. This invention provides a solution by reducing the spindle pitch within the usable area of ​​an existing spinning machine. Utility Model Content

[0005] The main purpose of this invention is to provide a spindle arrangement that reduces the footprint of existing ring spinning machines.

[0006] Another objective of this invention is to provide a spindle arrangement that reduces the working length of a ring spinning machine compared to existing arrangements.

[0007] Another objective of this invention is to provide a spindle arrangement for a ring spinning machine that improves output.

[0008] This invention provides a spindle arrangement for a ring spinning machine. Roving is fed from roving bobbins in a roving frame. The fed roving is conveyed to the drafting rollers by means of a cotton collector. The roving is further drafted in the drafting zone, i.e., the linear density of the roving is reduced. Twist is further imparted to the drafted fibers by means of rings and travelers. The twisted fiber strands, referred to as yarn, are further wound around bobbins mounted on the spindles. Multiple spindles are arranged on a spindle track. The axial distance between two adjacent spindles is called the spindle pitch. The spinning machine has multiple sections, each section consisting of a predetermined number of spindles.

[0009] According to this utility model, a textile ring spinning machine includes a roving frame area, a drafting area and a spindle area, wherein the distance from the center of the shaft to the center between two adjacent spindles is 65mm, that is, 64mm to 66mm, and the length of each segment is in the range of 1536mm to 1584mm.

[0010] According to one embodiment of the present invention, the total number of spindles in the ring spinning machine is increased. Each section contains 24 spindles, and multiple sections are arranged adjacent to each other along the length of the spinning machine. The length of each section is in the range of 1500mm to 1600mm, preferably in the range of 1536mm to 1584mm, for example, 1560mm.

[0011] According to one embodiment of the present invention, the spindle pitch interval of the spinning module is redefined to 64mm to 66mm, preferably 65mm, and therefore the segment length is redefined to 1560mm. Reducing the spindle pitch in a ring spinning machine is a crucial parameter for significantly improving production efficiency. By reducing the spindle pitch, the number of spindles per unit length increases, resulting in increased production efficiency. Since there are more spindles at a given length, a greater quantity of yarn can be produced simultaneously. All corresponding related components of the ring spinning machine are properly aligned according to the redefined spindle pitch length. This leads to a significant increase in machine productivity. Furthermore, it allows for better utilization of the available space on the ring spinning machine, optimizing its production capacity. According to the present invention, the total number of spindles in a ring spinning machine can be increased to 2400 or more.

[0012] According to one embodiment of the present invention, the ring spinning machine is a compact spinning machine or a non-compact spinning machine.

[0013] Other aspects and advantages of the present invention will become apparent from the following description taken in conjunction with the accompanying drawings, which illustrate the principles of the invention by way of example. Attached Figure Description

[0014] Figure 1 A side view of a textile ring spinning machine according to the present invention is shown.

[0015] Figure 2 A front view of a section of a textile ring spinning machine according to the present invention is shown. Detailed Implementation

[0016] According to one preferred embodiment of the present invention, the spindles of the ring spinning machine 1 are arranged in... Figure 1 and 2 As shown in the figure. The textile spinning machine 1 according to this utility model is not limited to a ring spinning machine, but can also be any yarn spinning equipment such as a non-compact and compact yarn ring spinning machine.

[0017] The roving is fed from the roving bobbin 3 in the roving frame 2. The fed roving is conveyed to the drafting assembly 4 by means of a cotton collector. The drafting assembly 4 consists of rubber rollers arranged on a grooved bottom roller. The roving is drafted in the drafting assembly 4. The linear density of the roving is reduced by changing the speed of the drafting rollers. The drafted roving further passes through the yarn guide 6 to the loops and travelers 5. With the help of the loops and travelers 5, the fiber bundle is twisted. The twisted fiber strands, referred to as yarn, are further wound onto a bobbin positioned on a spindle 7.

[0018] Spindles 7 are arranged on spindle tracks 8. According to this invention, the center-to-center distance between two adjacent spindles (i.e., spindle pitch G) is reduced to 64mm to 66mm, preferably 65mm, thereby increasing the number of spindles 7 in the spinning machine by increasing the number of sections. The length L of each section is in the range of 1500mm to 1600mm (preferably 1536mm to 1584mm, most preferably 1560mm). According to this invention, the spinning module spacing G is redefined as 65mm, therefore the section length L is redefined as 1560mm. Reducing the spindle pitch G in the ring spinning machine 1 is an important parameter for significantly improving production efficiency. By reducing the spindle pitch G, the number of spindles 7 per unit length increases, resulting in increased production efficiency. Since there are more spindles 7 at a given length, a larger quantity of yarn can be produced simultaneously. The reduction in spindle pitch G allows a larger number of spindles 7 to be accommodated at the same length of the ring spinning machine, resulting in an increase in the total output of the ring spinning machine 1. The redefined spindle spacing G according to this invention helps save 120mm of space per section, resulting in a 4.5m reduction in floor space for existing 1824-spindle machines. According to this invention, the total number of spindles in a ring spinning machine can be increased to 2400 or more. Furthermore, the increased section size due to the aforementioned space savings will increase productivity by 8% while reducing raw material consumption.

[0019] In view of this disclosure describing the present invention, all changes, modifications, and variations within the equivalent meaning and scope are considered to be within the scope and spirit of the present invention. It should be understood that the aspects and embodiments disclosed above can be used in any combination with each other. Several aspects and embodiments can be combined together to form another embodiment of this disclosure.
