Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a sliver tension adjustment device for a roving frame. Background Technology

[0002] When cotton slivers pass through the conveyor rollers of the roving frame, the tension should not be too tight or too loose. This process often requires tension control of the conveyor rollers to ensure that the flow rate of the processed cotton slivers is equal at all points on the continuous production line. This prevents material accumulation and breakage, ensuring the quality of the processed product, such as dimensional accuracy, straightness, winding tightness, shape, and material properties, meets standard requirements.

[0003] When adjusting the tension of the conveyor rollers on a roving frame, the spacing between the rollers is usually adjusted. This necessitates that the conveyor rollers be designed to be movable or detachable. However, if they are movable or detachable, the connection of the conveyor rollers is often not secure enough, and they are prone to loosening over time, leading to fluctuations in the tension of the sliver feed.

[0004] In addition, during the transport of slivers, the conveyor rollers of the roving frame sometimes become looser or tighter due to reasons in the preceding or following processes, so the tension of the sliver is always within a fluctuating range. This fluctuation cannot be adjusted by adjusting the spacing of the conveyor rollers, and there has always been a lack of an effective compensation method to reduce the fluctuation of sliver tension. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a sliver tension adjustment device for roving frames, so as to solve the technical problems of the non-fixed length of the conveyor roller being easy to loosen and the lack of compensation for the fluctuation of sliver tension in the prior art.

[0006] To achieve the above objectives, this utility model provides a sliver tension regulating device for a roving frame, including an active conveying roller for conveying the sliver, and the sliver tension regulating device further includes:

[0007] The end plates are connected to both ends of the active conveying roller, and one of the end plates is equipped with a power mechanism. The active conveying roller is rotatably connected to the end plate and connected to the output shaft of the power mechanism.

[0008] The left and right rotating rollers are located below the active conveying roller. The two ends of the left and right rotating rollers are provided with sliding connectors. The sliding connectors are slidably connected to the inside of the end plate, and a locking component is also provided between the sliding connectors and the end plate.

[0009] Furthermore, the cotton sliver is wound around the active conveying roller, the left rotating roller, and the right rotating roller. The sliding connector is also provided with a tensioning component, which acts on the left rotating roller and the right rotating roller to tension the cotton sliver.

[0010] Furthermore, the locking assembly includes a through groove located in the middle of the end plate and a fastening bolt located in the through groove. The through groove is vertically arranged, the inner end of the fastening bolt is threadedly connected to the sliding connector, and the outer end of the fastening bolt is located on the outer side of the end plate.

[0011] Furthermore, the outer end of the fastening bolt is larger than the width of the through groove.

[0012] Furthermore, the sliding connector is provided with a roller groove, and the roller shafts of the left and right rotating rollers are located in the roller groove and are movably connected thereto.

[0013] Furthermore, the tensioning assembly is located in the roller groove and between the roller shafts of the left and right rotating rollers.

[0014] Furthermore, the tensioning assembly includes a pressure box, which contains two push plates connected by a spring. Each push plate is supported on a roller on its respective side by a support assembly.

[0015] Furthermore, the support assembly includes a connecting rod and a push block. The push block is fixedly connected to the outer end of the connecting rod and is also rotatably connected to the roller shaft. The inner end of the connecting rod passes through the pressure box and is fixedly connected to the push plate.

[0016] Furthermore, the inner side of the end plate is provided with a sliding groove, and a connecting slide rod is fixedly connected to the sliding connector, the connecting slide rod being slidably connected in the sliding groove.

[0017] The beneficial effects of this utility model are as follows: 1. By setting a rotating active conveyor roller for conveying cotton slivers, the active conveyor roller cannot be displaced or disassembled. Therefore, the problem of loosening of the active conveyor roller is avoided.

[0018] 2. Adjusting the sliver tension on the roving frame is achieved through the left and right rotating rollers below the active conveyor roller. The left and right rotating rollers are mounted on a sliding connector, the position of which is adjustable. Loosening the fastening bolts loosens the sliding connector, allowing the position of the left and right rotating rollers to be adjusted, thus achieving sliver tension adjustment. Tightening the fastening bolts fixes the sliding connector. The operation is simple and convenient.

[0019] 3. A tensioning assembly is also provided within the sliding connector. A spring is installed in the pressure box of the tensioning assembly. The spring provides elastic force, which is then applied to the roller shaft via a push plate, connecting rod, and push block. This force then acts on the left and right rotating rollers, causing them to expand outwards and tighten the cotton sliver. This reduces fluctuations in the tightness of the cotton sliver.

[0029] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, when adjusting the tension of the conveyor rollers of a roving frame, the spacing between the conveyor rollers is usually adjusted. This necessitates that the conveyor rollers be designed to be movable or detachable. However, if they are movable or detachable, the connection of the conveyor rollers is often not secure enough, and they are prone to loosening over time, causing fluctuations in the tension of the sliver conveyor. Therefore, this design incorporates an active conveyor roller 101 for conveying the sliver 01. The active conveyor roller 101 has end plates 102 connected to both ends, and the active conveyor roller 101 cannot be displaced or disassembled.

[0030] One of the end plates 102 is equipped with a power mechanism, and the active conveying roller 101 is rotatably connected to the end plate 102 and connected to the output shaft of the power mechanism.

[0031] By setting a rotating active conveyor roller 101 for conveying the cotton sliver 01, the active conveyor roller 101 cannot be displaced or disassembled. Therefore, the problem of the active conveyor roller 101 becoming loose is avoided.

[0032] Additionally, a left rotating roller 104 and a right rotating roller 105 are arranged below the active conveying roller 101. Sliding connectors 103 are provided at both ends of the left and right rotating rollers 104 and 105. The two sliding connectors 103 are slidably connected to the inner sides of the two end plates 102, and a locking assembly is provided between the sliding connectors 103 and the end plates 102. The cotton sliver 01 is wound around the active conveying roller 101, the left rotating roller 104, and the right rotating roller 105.

[0033] The locking assembly includes a through groove 106 located in the middle of the end plate 102 and a fastening bolt 107 located in the through groove 106. The through groove 106 is vertically arranged, the inner end of the fastening bolt 107 is threadedly connected to the sliding connector 103, and the outer end of the fastening bolt 107 is located on the outer side of the end plate 102.

[0034] Preferably, the outer end of the fastening bolt 107 is larger than the width of the through groove 106.

[0035] Adjusting the sliver tension on the roving frame is achieved through the left rotating roller 104 and the right rotating roller 105 located below the active conveyor roller 101. The left rotating roller 104 and the right rotating roller 105 are mounted on the sliding connector 103, and the position of the sliding connector 103 is adjustable. Loosening the fastening bolt 107 loosens the sliding connector 103, allowing the position of the left rotating roller 104 and the right rotating roller 105 to be adjusted, thereby achieving sliver tension adjustment. Tightening the fastening bolt 107 fixes the sliding connector 103, making the operation simple and convenient.

[0036] The second aspect of this utility model is as follows: Figure 1 , Figure 3 and Figure 4 As shown, in order to compensate for the fluctuation of the tightness of the cotton strip, a tensioning component is also provided in the sliding connector 103. The tensioning component acts on the left rotating roller 104 and the right rotating roller 105 to tighten the cotton strip 01.

[0037] Specifically, the sliding connector 103 is provided with a roller groove 110, and the roller shafts 116 of the left rotating roller 104 and the right rotating roller 105 are located in the roller groove 110 and are movably connected thereto. The tensioning assembly is located in the roller groove 110 and between the roller shafts 116 of the left rotating roller 104 and the right rotating roller 105.

[0038] The tensioning assembly includes a pressure box 111, which contains two push plates 114 and a spring 115 connecting the two push plates 114. Each of the two push plates 114 is supported on a roller 116 on its respective side by a support assembly.

[0039] The support assembly includes a connecting rod 112 and a push block 113. The push block 113 is fixedly connected to the outer end of the connecting rod 112 and is also rotatably connected to the roller shaft 116. The inner end of the connecting rod 112 passes through the pressure box 111 and is fixedly connected to the push plate 114.

[0040] Preferably, the inner side of the end plate 102 is also provided with a sliding groove 108, and a connecting slide rod 109 is fixedly connected to the sliding connector 103, and the connecting slide rod 109 is slidably connected in the sliding groove 108.

[0041] The pressure box 111 in the tensioning assembly contains a spring 115. The spring 115 provides elastic force, which is then applied to the roller 116 via the push plate 114, connecting rod 112, and push block 113. This force then acts on the left and right rotating rollers 104 and 105, causing them to expand outward and tighten the cotton sliver 01. This reduces fluctuations in the tension of the cotton sliver.

[0042] In summary, this utility model uses a rotating active conveyor roller 101 to transport the sliver 01. The active conveyor roller 101 cannot be displaced or disassembled, thus avoiding the problem of loosening. The tension of the sliver on the roving frame is adjusted via a left rotating roller 104 and a right rotating roller 105 located below the active conveyor roller 101. These rollers are mounted on a sliding connector 103, which is adjustable. Loosening the fastening bolt 107 loosens the sliding connector 103, allowing adjustment of the positions of the left and right rotating rollers 104 and 105 to regulate the sliver tension. Tightening the fastening bolt 107 fixes the sliding connector 103, making the operation simple and convenient.

[0043] Additionally, a tensioning assembly is provided within the sliding connector 103. A spring 115 is located within the pressure box 111 of the tensioning assembly. The spring 115 provides elastic force, which is then applied to the roller shaft 116 via the push plate 114, connecting rod 112, and push block 113. This force then acts on the left and right rotating rollers 104 and 105, causing them to expand outwards and tighten the cotton sliver 01. This reduces fluctuations in the tightness of the cotton sliver.
