Technical Field

[0001] This application relates to the field of spinning equipment technology, and in particular to a spinning device for roving with a large dry weight of 8.5g. Background Technology

[0002] In traditional spinning processes, roving weight is typically low, such as 6.5g dry weight, which leads to a large number of pre-spinning equipment, high energy consumption, and high costs. With the continuous development of spinning technology, how to reduce spinning costs, reduce energy consumption, and improve yarn quality has become the focus of the industry. Therefore, it is necessary to improve existing spinning equipment to meet the spinning needs of high-weight roving. Utility Model Content

[0003] The purpose of this application is to provide a spinning device for roving with a large dry weight of 8.5g, which has the advantages of reducing spinning costs, reducing energy consumption, and improving yarn quality, and solves the problems mentioned in the background art.

[0004] The roving high-weight dry weight 8.5g spinning device provided in this application adopts the following technical solution: the roving high-weight dry weight 8.5g spinning device includes a cradle, and the cradle is provided with an upper roller assembly, a middle roller assembly and a lower roller assembly in sequence inside the cradle. The pressure of the cradle is reduced by 60N compared with the roving 6.5g dry weight.

[0005] The middle roller assembly includes a middle support and a middle roller rotatably connected to the middle support, and a large rubber roller with a diameter of ∮35 is sleeved at the end of the middle roller;

[0006] The upper roller assembly includes an upper support and an upper roller rotatably connected to the upper support. The end of the upper roller is fitted with a carbon fiber coated rubber roller with a diameter of ∮28. The bottom of the upper support is fixedly connected to an upper pin frame, which is an extended upper pin frame.

[0007] The lower roller assembly includes a lower support and a lower roller rotatably connected to the lower support. The end of the lower roller is fitted with a carbon fiber coated rubber roller with a diameter of ∮28.

[0008] By adopting the above technical solutions, and by using high-weight roving (8.5g dry weight replacing 6.5g dry weight) technology, the equipment investment in the pre-spinning process is reduced, saving land rental and purchase costs, optimizing the production layout, improving space utilization, and reducing spinning costs. By reducing the pressure of the cradle by 60N compared to 6.5g dry weight roving, fine yarn production is smoother and energy consumption is reduced, saving the company a significant amount of energy costs. By increasing the diameter of the carbon fiber-coated rubber roller at the top roller end to ∮28 and the large rubber roller to ∮35, and lengthening the top roller, the fiber holding force and bundling ability are enhanced, the fiber floating area is reduced, fiber loss and waste are reduced, fiber cohesion is increased, the 40s yarn forming level is improved, and the yarn quality is enhanced.

[0009] Preferably, the top of the middle bracket is fixedly connected to the cradle by bolts.

[0010] By adopting the above technical solution, the stability and rigidity of the middle roller assembly are ensured by fixing the middle support and the cradle with bolts. This avoids the problem of unstable tension during spinning caused by loosening or displacement of the assembly, thereby improving the continuity and stability of spinning, reducing downtime and maintenance costs caused by equipment failure, and facilitating subsequent disassembly and maintenance by fixing the middle support and the cradle with bolts.

[0011] Preferably, the upper support is slidably connected to the inside of the rocker arm, a sliding plate is fixedly connected to the top of the upper support, and a sliding groove is provided inside the rocker arm, through which the sliding plate is slidably connected to the rocker arm.

[0012] By adopting the above technical solution, the sliding connection design between the upper support and the cradle allows the upper roller assembly to be flexibly adjusted according to actual needs, facilitating the adjustment of the roller spacing as required, and improving the flexibility and adaptability of the equipment.

[0013] Preferably, each of the slide plates has two positioning rods fixedly connected to its outer surface, and each positioning rod has a positioning nut threaded onto its outer circumferential surface.

[0014] By adopting the above technical solution, the design of the positioning rod and positioning nut provides a precise positioning and fixing mechanism for the sliding of the upper support. After adjusting the position of the upper support, the position of the slide plate can be firmly locked by rotating the positioning nut, preventing it from shifting due to vibration or external force during the spinning process, thereby ensuring the stability and consistency of the spinning process and guaranteeing the spinning quality.

[0015] Preferably, a shock-absorbing plate is sleeved on the outside of the positioning rod, and the shock-absorbing plate is disposed between the positioning nut and the rocker arm.

[0016] By adopting the above technical solution, the introduction of the damping plate effectively absorbs the vibration and impact energy generated during the spinning process, thereby preventing the positioning nut from easily loosening and causing the upper support and upper roller to shift during the spinning operation, thus affecting the quality of the spinning operation.

[0017] Preferably, the top end of the lower support is fixedly connected to the cradle by bolts.

[0018] By adopting the above technical solution, the lower bracket is fixedly connected to the cradle with bolts, which ensures the stability of the connection between the lower bracket and the cradle and facilitates the subsequent disassembly and maintenance of the lower bracket.

[0019] Preferably, the extended upper bracket model is Bx-6939Ls, replacing the original model sx-6839D.

[0020] By adopting the above technical solutions, the design of lengthening the upper roller, combined with increasing the diameter of the carbon fiber-coated rubber roller at the end of the upper roller to ∮28, and increasing the diameter of the large rubber roller to ∮35, increases the contact area and gripping force between the fiber and the roller, enhances the fiber gripping force and bundling ability, reduces the fiber floating area, increases fiber cohesion, and improves yarn quality.

[0021] Preferably, the rocker arm is an aluminum alloy frame, and the outer surface of the rocker arm is coated with an anti-rust coating.

[0022] By adopting the above technical solution, the cradle 1 made of aluminum alloy has the advantages of light weight, high strength and corrosion resistance, which helps to reduce the overall weight of the equipment, reduce energy consumption and improve the durability and service life of the equipment. At the same time, the anti-rust coating on the outer surface effectively prevents the corrosion problem of the cradle 1, further extending the service life of the equipment and reducing maintenance costs.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] This 8.5g dry weight roving spinning device reduces equipment investment in pre-spinning processes by adopting 8.5g dry weight roving (replacing 6.5g dry weight) technology, saving land rental and purchase costs, optimizing production layout, improving space utilization, and reducing spinning costs. By reducing the cradle pressure by 60N compared to 6.5g dry weight roving, fine yarn production becomes smoother and energy consumption is reduced, saving the company significant energy costs. By increasing the carbon fiber-coated rubber roller at the upper roller end to a diameter of ∮28 and the large rubber roller to a diameter of ∮35, and lengthening the upper roller, fiber holding power and bundling ability are enhanced, the fiber floating area is reduced, fiber loss and waste are reduced, fiber cohesion is increased, the 40s yarn forming level is improved, and yarn quality is enhanced.

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0033] Example 1: A spinning device for roving with a large dry weight of 8.5g, referring to... Figure 1 , Figure 2 and Figure 3 It includes a rocker arm 1, and inside the rocker arm 1 are arranged an upper roller assembly 2, a middle roller assembly 3 and a lower roller assembly 4 in sequence. The pressure applied by the rocker arm 1 is reduced by 60N compared to the dry weight of 6.5g roving.

[0034] The middle roller assembly 3 includes a middle support 301 and a middle roller 302 rotatably connected to the middle support 301. A large rubber roller 303 with a diameter of ∮35 is sleeved at the end of the middle roller 302.

[0035] The top of the middle support 301 is fixedly connected to the cradle 1 by bolts. The fixed connection between the middle support 301 and the cradle 1 by bolts ensures the stability and rigidity of the middle roller assembly 3, avoids the problem of unstable tension during spinning caused by loosening or displacement of the assembly, thereby improving the continuity and stability of spinning, reducing downtime and maintenance costs caused by equipment failure. At the same time, the fixed connection between the middle support 301 and the cradle 1 by bolts also facilitates subsequent disassembly and maintenance.

[0036] The upper roller assembly 2 includes an upper support 201 and an upper roller 202 rotatably connected to the upper support 201. The end of the upper roller 202 is fitted with a carbon fiber coated rubber roller with a diameter of ∮28. The bottom of the upper support 201 is fixedly connected to an upper roller frame 207, which is an extended upper roller.

[0037] The extended upper roller 207, model Bx-6939Ls, replaces the original model sx-6839D. The extended upper roller design, combined with the enlarged carbon fiber-coated rubber roller at the end of the upper roller 202 to a diameter of ∮28, and the enlarged large rubber roller 303 to a diameter of ∮35, increases the contact area and gripping force between the fiber and the roller, enhances the fiber gripping force and bundling ability, reduces the fiber floating area, increases fiber cohesion, and improves yarn quality.

[0038] The lower roller assembly 4 includes a lower support 401 and a lower roller 402 rotatably connected to the lower support 401. The end of the lower roller 402 is fitted with a carbon fiber coated rubber roller with a diameter of ∮28.

[0039] The top of the lower bracket 401 is fixedly connected to the cradle 1 by bolts. The fixed connection between the lower bracket 401 and the cradle 1 by bolts ensures the stability of the connection between the lower bracket 401 and the cradle 1 and facilitates the subsequent disassembly and maintenance of the lower bracket 401.

[0040] The cradle 1 is made of aluminum alloy and its outer surface is coated with an anti-rust coating. The cradle 1 made of aluminum alloy has the advantages of being lightweight, high-strength, and corrosion-resistant, which helps to reduce the overall weight of the equipment, reduce energy consumption, and improve the durability and service life of the equipment. At the same time, the anti-rust coating on the outer surface effectively prevents the corrosion of the cradle 1, further extending the service life of the equipment and reducing maintenance costs.

[0041] Example 2: A spinning device for roving with a large dry weight of 8.5g, referring to... Figure 3 , Figure 4 and Figure 5 The upper support 201 is internally slidably connected to the rocker arm 1. A slide plate 203 is fixedly connected to the top of the upper support 201. A slide groove 204 is provided inside the rocker arm 1. The slide plate 203 is slidably connected to the rocker arm 1 through the slide groove 204. The sliding connection design between the upper support 201 and the rocker arm 1 allows the upper roller assembly 2 to be flexibly adjusted according to actual needs, and it is convenient to adjust the roller spacing according to requirements, thereby improving the flexibility and adaptability of the equipment.

[0042] Two positioning rods 205 are fixedly connected to the outer surface of each slide plate 203. Each positioning rod 205 has a positioning nut 206 threadedly connected to its outer circumference. The design of the positioning rods 205 and positioning nuts 206 provides a precise positioning and fixing mechanism for the sliding of the upper support 201. After adjusting the position of the upper support 201, the position of the slide plate 203 can be firmly locked by rotating the positioning nut 206, preventing it from shifting due to vibration or external force during the spinning process. This ensures the stability and consistency of the spinning process and guarantees the spinning quality.

[0043] The positioning rod 205 is fitted with a shock absorber 208. The shock absorber 208 is located between the positioning nut 206 and the cradle 1. The introduction of the shock absorber 208 effectively absorbs the vibration and impact energy generated during the spinning process, thereby preventing the positioning nut 206 from easily loosening and causing the upper support 201 and upper roller 202 to shift during the spinning operation, which would affect the quality of the spinning operation.

[0044] It should be noted that the cradle 1 of the spinning device needs to be installed on the spinning machine for spinning processing.

[0045] The implementation principle of this application embodiment is as follows: Adopting high-weight roving (8.5g dry weight replacing 6.5g dry weight) technology reduces equipment investment in the pre-spinning process, saves land rental and purchase costs, optimizes production layout, improves space utilization, and reduces spinning costs. Simultaneously, reducing the pressure on the cradle 1 by 60N compared to 6.5g dry weight roving makes fine yarn production smoother and reduces energy consumption, saving the company significant energy costs. The extended upper roller design, combined with an enlarged carbon fiber-coated rubber roller at the end of the upper roller 202 to a diameter of ∮28, and an enlarged rubber roller 303 in the middle roller assembly 3 to a diameter of ∮35, increases the contact area and gripping force between the fiber and the roller, enhancing fiber gripping and bundling capabilities. The reduced floating zone increases fiber cohesion, resulting in significantly better yarn evenness in 40s compared to before the upgrade, thus improving yarn quality. The sliding connection between the upper support 201 and the rocker arm 1 allows the upper roller assembly 2 to be flexibly adjusted according to actual needs, facilitating roller spacing adjustment and enhancing equipment flexibility and adaptability. Tightening the positioning nut 206 securely locks the slide plate 203, ensuring the stability of the upper roller assembly 2 and preventing displacement due to vibration or external forces during spinning, thereby guaranteeing the stability and consistency of the spinning process. Loosening the positioning nut 206 releases the restriction on the slide plate 203, allowing the upper support 201 to move and adjust the roller spacing.
