Abstract

The invention relates to a compact spinning reduction device which comprises a roller stand and a clamping block. The roller stand is provided with a first limiting protrusion and a clamping groove. The clamping groove is clamped with the clamping part of the negative pressure tube plug; a second limiting bulge is arranged on the clamping block; limiting holes are formed in the two ends of the flute pipe respectively, and the flute pipe is arranged between the adjacent roller stands. When compact spinning is carried out, the first limiting protrusions are sleeved with the limiting holes. When ring spinning is implemented, the clamping blocks are arranged in the clamping grooves, and the second limiting protrusions on the adjacent clamping blocks are oppositely arranged. And the limiting hole is formed in the second limiting bulge in a sleeving manner.

[0037] Figure 1 A schematic diagram of the three-dimensional structure of the compact spinning reduction device of the present invention in the compact spinning mode is shown. Figure 2 A schematic diagram of the three-dimensional structure of the compact spinning reduction device of the present invention in the ring spinning mode is shown. Figure 3 A partial enlarged view of the compact spinning reduction device of the present invention at position A is shown. Figure 4 A schematic diagram of the three-dimensional structure of a block in the compact spinning reduction device of the present invention is shown. Figure 5 A schematic diagram of the three-dimensional structure of a flute tube in the compact spinning reduction device of the present invention is shown. Figure 7 The schematic diagram of the structure of the roller seat in the compact spinning reduction device of the present invention in the inner direction is shown. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 A compact spinning reduction device is used to switch between compact spinning and ring spinning. The compact spinning reduction device includes a roller seat 1 and a clamping block 4. A first limiting protrusion 11 is provided on the roller seat 1 and a clamping slot 221 is provided. The flute tube 5 can be fixed between the two roller seats 1 through the first limiting protrusion 11. The clamping slot 221 clamps the clamping part of the negative pressure tube plug 7, and the negative pressure tube is fixed between the two roller seats 1 through the clamping slot 221. A second limiting protrusion 414 is provided on the clamping block 4, and the clamping block 4 can also be clamped in the clamping slot 221. Among them, limiting holes 51 are respectively provided at both ends of the flute tube 5, and the flute tube 5 is arranged between adjacent roller seats 1. When compact spinning is implemented, the limiting hole 51 is sleeved on the first limiting protrusion 11. When ring spinning is implemented, the clamping block 4 is arranged in the clamping slot 221, and the second limiting protrusions 414 on adjacent clamping blocks 4 are arranged facing each other. The limiting hole 51 is sleeved on the second limiting protrusion 414. When it is necessary to switch from compact spinning to ring spinning, it is only necessary to remove the negative pressure tube from between the card slots 221, fix the card block 4 in the card slot 221, and then switch the flute tube 5 fixed on the first limiting protrusion 11 to the second limiting protrusion 414 to complete the switch. The roller seat 1 of the compact spinning reduction device can fix the negative pressure tube and the flute tube 5 at the same time. Compared with ordinary compact spinning equipment, no additional flute tube 5 reduction support is set, and the structure is not complicated. The production cost is low, and the volume of the equipment is not expanded. At the same time, the compact spinning reduction device is easy to switch between the two modes of compact spinning and ring spinning, which can adapt to the needs of different products, thereby quickly responding to market changes, reducing equipment downtime, and improving overall production efficiency.

[0038] In this embodiment, the connecting piece 41 on the block 4 is set at an angle of 30° with the length direction of the block 4. When the flute tube 5 is fixed on the roller seat 1 through the second limiting protrusion 414, the distance from the yarn 8 to the flute tube 5 is the distance from the flute tube 5 to the yarn 8 in ring spinning. At this time, the distance from the yarn 8 to the flute tube 5 is moderate, and the flute tube 5 can absorb the broken ends, hairiness, floating ends and fibers of the yarn in time, thereby improving the spinning quality and keeping the air in the production workshop clean.

[0039] Figure 6 The three-dimensional structural diagram of the switching seat in the compact spinning reduction device of the present invention is shown. Figure 2 , Figure 3 and Figure 6 The roller seat 1 is provided with a detachable switch seat 2, and the card slot 221 is provided on the switch seat 2. By replacing the switch seat 2, the card slot 221 can be quickly maintained and replaced to adapt to negative pressure tubes and flute tubes 5 of different specifications, thereby improving the adaptability of the equipment.

[0040] Preferably, a first limiting groove 23 is formed at the bottom of the switching seat 2, and the upper end of the roller seat 1 extends into the first limiting groove 23. The threaded fastener 6 passes through the base 21 and is connected to the roller seat 1 to fix the switching seat 2 on the roller seat 1.

[0041] More preferably, the switching seat 2 includes a base 21, a side plate 22 and a swing arm 3. The side plate 22 is arranged on the base 21, and a slot 221 is provided on the side plate 22. The swing arm 3 is rotatably connected to the side plate 22. When the block 4 is arranged in the slot 221, the swing arm 3 is rotated, and the swing arm 3 contacts and squeezes the block 4 toward the bottom of the slot 221. In the compact spinning mode, the negative pressure pipe plug 7 is arranged in the slot 221, and the swing arm 3 is rotated to contact the negative pressure pipe plug 7, so that the negative pressure pipe plug 7 can be fixed in the slot 221, thereby increasing the connection strength between the negative pressure pipe plug 7 and the switching seat 2. In the ring spinning mode, the block 4 is arranged in the slot 221, and the swing arm 3 is rotated to contact the block 4, so that the block 4 can be fixed in the slot 221, thereby increasing the connection strength between the block 4 and the switching seat 2.

[0042] The threaded fastener 6 can be a bolt, a screw, a threaded rod, etc. The threaded fastener 6 is connected by interlocking threads, has high connection strength, is not easy to loosen, and the threaded connection can withstand large tensile and shear forces, has high reliability and is easy to disassemble.

[0043] Figure 8 The vertical cross-sectional structure diagram of the roller seat in the compact spinning reduction device of the present invention is shown. Figure 2 , Figure 3 and Figure 8Two side plates 22 are provided, and a second limiting groove 24 is formed between the two side plates 22, and the swing arm 3 is provided in the second limiting groove 24. A rotating shaft 31 is provided in the second limiting groove 24, and the swing arm 3 is rotatably connected to the switching seat 2 through the rotating shaft 31. The side plates 22 completely limit the movement of the swing arm 3 along the rotating shaft 31, so as to prevent the swing arm 3 from lateral movement and shaking along the rotating shaft 31, thereby affecting the stability of the negative pressure pipe plug 7 or the clamping block 4 fixed in the clamping groove 221. In this way, the stability of the entire compact spinning reduction device is guaranteed, and the probability of failure is reduced.

[0044] In this embodiment, an extension portion 32 and a handle portion 33 are extended from one end of the middle swing arm 3 near the slot 221. The extension portion 32 is arranged on the side of the swing arm 3 near the switching seat 2. There is an arc transition between the extension portion 32 and the main body of the swing arm 3. The contact area between the swing arm 3 and the negative pressure pipe plug 7 or the block 4 is increased by the arc used for transition. The increase in the contact area between the swing arm 3 and the negative pressure pipe plug 7 or the block 4 can effectively disperse the pressure, increase the connection strength of the contact part and improve the stability of the system. The handle portion 33 is arranged on the side of the swing arm 3 away from the switching seat 2, which is convenient for the operator to pull the swing arm 3 and improve the operating efficiency of the swing arm 3.

[0045] Please refer to Figure 2 and Figure 3 , a connecting piece 41 is respectively provided on the block 4 and the roller seat 1. The connecting piece 41 includes a first section 411 and a second section 413. The second section 413 is bent toward the side away from the roller seat 1. The first limiting protrusion 11 or the second limiting protrusion 414 is provided on the second section 413, and a gap is formed between the second section 413 and the roller seat 1. The interval between the connecting pieces 41 can be changed by squeezing the second section 413 and utilizing the elastic deformation of the second section 413 to approach the side of the roller seat 1. When disassembling the flute tube 5, the second section 413 is squeezed so that the interval between the second sections 413 on both sides of the length of the flute tube 5 is increased. At this time, the connecting piece 41 and the flute tube 5 can be conveniently separated, and then the flute tube 5 can be quickly disassembled. The increased disassembly speed of the flute tube 5 can reduce the speed of the compact spinning reduction device switching between the compact spinning and ring spinning working modes, reduce the downtime of the compact spinning heat exchange device, and improve production efficiency.

[0046] Preferably, the connecting piece 41 is connected to the clamping block 4 or the roller seat 1 through the threaded fastener 6. A waist-shaped hole 412 is provided on the connecting piece 41. The threaded fastener 6 passes through the waist-shaped hole 412 and is connected to the clamping block 4 or the roller seat 1. Along the opening direction of the waist-shaped hole 412, the position of the threaded fastener 6 in the waist-shaped hole 412 can be easily adjusted, thereby changing the position of the connecting piece 41 on the roller seat 1. The setting of the waist-shaped hole 412 improves the flexibility of the position of the connecting piece 41.

[0047] More preferably, two connecting pieces 41 are provided on the clamping block 4. The two connecting pieces 41 are provided on the opposite sides of the clamping block 4. In this way, when multiple roller seats 1 are arranged in parallel for production, only one clamping block 4 is required to be provided on one roller seat 1, so that the flute tubes 5 can be provided on the opposite sides of the roller seat 1, which greatly simplifies the number of parts in the compact spinning reduction device. The reduction in the number of parts reduces the cost of raw materials and processing costs. At the same time, fewer parts means fewer connection points between parts, thereby reducing the possibility of failure at the connection. This improves the overall performance and service life of the compact spinning reduction device.

[0048] The specific workflow of the present invention is as follows:

[0049] When switching the compact spinning mode to the ring spinning mode. The operator first pushes the flute tube 5 along one side of the length direction of the flute tube 5. The flute tube 5 pushes the second section 413, causing the connecting piece 41 to produce elastic deformation, and the second section 413 deforms toward the side close to the roller seat 1. At this time, the distance between the two connecting pieces 41 connecting the flute tube 5 increases, and the first limiting protrusion 11 can be pulled out from the end of the flute tube 5, and then the flute tube 5 is removed from between the two connecting pieces 41. Then the operator pulls the handle 33 to drive the swing arm 3 to move away from the slot 221. At this time, the swing arm 3 no longer interferes with the movement of the negative pressure pipe plug 7, and the negative pressure pipe plug 7 is taken out of the slot 221, and then the entire negative pressure pipe is removed. Then move the block 4 and insert the block 4 into the slot 221. Then squeeze the second section 413 of the connecting piece 41 on the block 4, so that the distance between the second sections 413 on the two blocks 4 increases. At this time, the second limiting protrusion 414 is extended into the end of the flute tube 5, and the flute tube 5 is fixed between the two roller seats 1 through the second limiting protrusion 414. Finally, the handle 33 is pulled to drive the swing arm 3 to swing toward the side close to the card slot 221 until the swing arm 3 contacts the card block 4, completing the switching of the spinning mode.

[0050] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
