Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to a roving frame for processing sliver of wool-polyester fabric. Background Technology

[0002] The roving frame for processing wool-polyester blended slivers belongs to the field of textile machinery. It is mainly used to draft, twist, and wind wool-polyester blended slivers into rovings to provide raw materials for subsequent spinning processes. This type of equipment plays a key role in the production of wool-polyester fabrics. It needs to take into account the crimp characteristics of wool fibers and the smoothness of polyester fibers to ensure that the slivers maintain uniform tension and surface smoothness during processing, while meeting process requirements such as efficient dust removal and precise guidance.

[0003] In existing technologies, traditional roving frames have several shortcomings in processing wool-polyester slivers. First, the dust removal structure is poorly designed; most machines only use simple brushes or suction ports for surface cleaning, which cannot effectively remove the static-attracted dust and short fibers generated during wool-polyester fiber processing. Furthermore, the suction system is prone to efficiency reduction due to filter clogging, requiring frequent downtime for maintenance. Second, the fixed position of the guide rollers makes it difficult to adapt to the tension requirements of different sliver specifications, resulting in uneven yarn tension during drafting and affecting roving quality. In addition, traditional adjustment mechanisms rely on mechanical transmission and manual gear replacement, failing to dynamically adjust the spacing of the side column in real time. The limited use of automated adjustment components such as bidirectional lead screws leads to poor equipment adaptability and low production efficiency. Simultaneously, wool-polyester fibers easily attract dust due to static electricity, and the traditional inlet and outlet structures lack elastic buffering design, easily causing fiber wear or breakage, further affecting the stability of the finished product. Therefore, a roving frame for processing wool-polyester fabric slivers is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a roving frame for sliver processing of wool and polyester fabrics, which solves the technical problems of unreasonable dust removal structure design, where most equipment only performs surface cleaning with simple brushes or dust suction ports, failing to effectively remove statically adsorbed dust and short fibers generated during wool and polyester fiber processing, and where the dust suction system is prone to efficiency reduction due to filter clogging, requiring frequent machine shutdowns for maintenance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a roving frame for processing wool-polyester fabric sliver, comprising:

[0006] The outer casing and the control components are located on the front of the outer casing. The upper sides of both sides of the outer casing are evenly provided with inlets and outlets, and side rollers are rotatably connected to both ends of the inlets and outlets. The inner walls of the inlets and outlets are all equipped with elastic sleeves.

[0007] The guide roller is rotatably connected to the lower two sides of the outer shell, and side rotating columns are evenly provided above the guide roller, with dust removal components fitted on the outer surface of the side rotating columns;

[0008] A bidirectional lead screw is rotatably connected to the upper center of both sides of the outer casing, and a connecting rod is connected between the ends of adjacent bidirectional lead screws. A first drive motor is coaxially connected to the end of the bidirectional lead screw, and sliding blocks are sleeved on both sides of the outer surface of the bidirectional lead screw. The side rotating column is rotatably connected to the sliding block.

[0009] The vacuum cleaner is located at the lower center of both sides of the outer casing, and the air outlet of the vacuum cleaner is connected to a dust collection box, and the air outlet of the dust collection box is connected to an exhaust fan.

[0010] When using this roving frame for processing wool and polyester sliver, the equipment is first started by controlling the components. The wool and polyester sliver enters from the inlet and outlet at the upper part of both sides of the roving frame housing. The side rollers at both ends of the inlet and outlet rotate to assist the sliver in. The elastic sleeves on the inner walls of the inlet and outlet protect the sliver. Meanwhile, the internal mechanism components of the roving frame housing are common mechanisms on the market, so they will not be described in detail here.

[0011] After the cooked strip enters, it is guided by the guide rollers on both sides of the lower part of the outer shell. The side rotating column above the guide roller supports the cooked strip. The dust removal parts on the outer surface of the side rotating column remove the dust from the surface of the cooked strip. The first drive motor starts and drives the bidirectional lead screw to rotate. Since the ends of adjacent bidirectional lead screws are connected by connecting rods, multiple bidirectional lead screws rotate synchronously. The sliding blocks on both sides of the outer surface of the bidirectional lead screw move accordingly, thereby driving the side rotating column to move to adapt to different specifications of cooked strip.

[0012] The dust removed by the dust removal components is sucked into the dust collection cylinder by the exhaust fan, and then enters the dust collection box for collection through the air outlet and filter components of the dust collection cylinder.

[0013] Preferably, pulleys are rotatably connected to both sides of the back of the outer casing, and the pulleys are connected to the ends of the corresponding bidirectional lead screws, with a transmission belt between the pulleys. When the bidirectional lead screw rotates, the pulleys connected to the ends of the bidirectional lead screws rotate accordingly. Under the action of the transmission belt, the pulleys on the other side rotate synchronously, thereby driving the corresponding bidirectional lead screws to rotate synchronously.

[0014] Preferably, the outer surface of the vacuum cleaner is provided with uniformly spaced suction holes, all of which are connected to a confluence pipe at the air outlet of the vacuum cleaner. During the vacuuming process, dust enters the vacuum cleaner through the uniformly spaced suction holes on the outer surface of the vacuum cleaner, and then enters the confluence pipe from the air outlet of the vacuum cleaner.

[0015] Preferably, the outlet end of the merging pipe is connected to the inlet end of the dust collection box, and the dust collection box is connected to the back of the outer casing. The dust collected in the merging pipe enters the inlet end of the dust collection box through its outlet end and is finally stored in the dust collection box, which is kept in a fixed position by its connection to the back of the outer casing.

[0016] Preferably, dust discharge slots are provided on the lower parts of both sides of the dust collection box, and a rotating shaft is rotatably connected to the center of the inner cavity of the dust discharge slot. When dust stored in the dust collection box needs to be discharged, it can be discharged through the dust discharge slots on both sides. The rotating shaft rotates in the center of the inner cavity of the dust discharge slot, providing an auxiliary function for dust discharge.

[0017] Preferably, a second drive motor is mounted on both sides of the front and back of the dust collection box via a motor mount, and the second drive motor is coaxially connected to the end of the rotating shaft. When it is necessary to drive the rotating shaft to rotate, the second drive motor mounted on both sides of the front and back of the dust collection box via the motor mount is started. The operation of the second drive motor drives the end of the rotating shaft coaxially connected to it to rotate, thereby causing the entire rotating shaft to rotate.

[0018] Preferably, dust scraper plates are installed on both the upper and lower parts of the outer surface of the rotating shaft, and the outer surface of the dust scraper plates slides against the inner wall of the dust discharge trough. When the rotating shaft rotates, the dust scraper plates installed on the upper and lower parts of its outer surface rotate together, and the outer surface of the dust scraper plates slides against the inner wall of the dust discharge trough, scraping the inner wall of the dust discharge trough during the rotation.

[0019] Preferably, a filter screen is installed at the bottom of the inner cavity of the dust collection box, and the filter screen is designed with a higher center and lower ends. The outer surface of the dust scraper is slidably attached to both sides of the upper surface of the filter screen. After dust enters the dust collection box, it falls onto the filter screen at the bottom of the inner cavity. The design of the filter screen, with its higher center and lower ends, causes the dust to accumulate on both sides. At the same time, when the dust scraper rotates, its outer surface slides against both sides of the upper surface of the filter screen, scraping away the dust on the filter screen.

[0020] Compared with the prior art, the present invention provides a roving frame for sliver processing of wool-polyester fabrics, which has the following beneficial effects:

[0021] This roving frame for processing wool-polyester slivers features guide rollers that guide the conveying path of the slivers, ensuring stable movement of the fabric along a preset trajectory. Dust-cleaning components on the outer surface of the side rotating columns clean the fabric as it passes, reducing dust and impurities. Driven by a first drive motor, the bidirectional screws rotate, moving the sliding blocks on both sides and adjusting the position of the side rotating columns to accommodate slivers of different widths, thus improving the equipment's versatility. Furthermore, the connecting rods at the ends of adjacent bidirectional screws ensure synchronized movement, resulting in more coordinated and consistent adjustment of the side rotating column positions.

[0022] The dust collection cannon generates suction under the action of the exhaust fan to suck up the dust cleaned by the dust removal components. It is then transported to the dust collection box through the air outlet for collection, which prevents dust from accumulating inside the outer shell and affecting the processing quality of wool and polyester fabric slivers. At the same time, it keeps the internal environment of the equipment clean, which is conducive to improving the processing effect and the service life of the equipment. Attached Figure Description

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] This invention provides a technical solution: a roving frame for processing wool-polyester fabric sliver, comprising: (see details) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The outer shell 1 and the control component 2 are disposed on the front of the outer shell 1. The upper sides of the outer shell 1 are evenly provided with inlet and outlet 3, and the two ends of the inlet and outlet 3 are rotatably connected with side rollers 5. The inner walls of the inlet and outlet 3 are all equipped with elastic sleeves 4.

[0034] Guide roller 6 is rotatably connected to the lower two sides of the outer shell 1, and side rotating columns 9 are evenly provided above the guide roller 6, and dust removal components are sleeved on the outer surface of the side rotating columns 9.

[0035] A bidirectional lead screw 7 is rotatably connected to the upper center of both sides of the outer casing 1, and a connecting rod 10 is connected between the ends of adjacent bidirectional lead screws 7. A first drive motor 13 is coaxially connected to the end of the bidirectional lead screw 7, and sliding blocks 8 are sleeved on both sides of the outer surface of the bidirectional lead screw 7. The side rotating column 9 is rotatably connected to the sliding block 8.

[0036] The vacuum cleaner 14 is located at the lower center of both sides of the outer casing 1, and the air outlet of the vacuum cleaner 14 is connected to the dust collection box 17, and the air outlet of the dust collection box 17 is connected to the exhaust fan 23.

[0037] When using this roving frame for processing wool and polyester fabric sliver, the equipment is first started by controlling component 2. The wool and polyester fabric sliver enters from the inlet and outlet 3 on the upper part of both sides of the roving frame housing 1. The side rollers 5 at both ends of the inlet and outlet 3 rotate to assist the sliver in entering. The elastic sleeves 4 on the inner wall of the inlet and outlet 3 protect the sliver. At the same time, the internal mechanism components of the roving frame housing 1 are common mechanisms on the market, so they will not be described in detail here.

[0038] After the cooked strip enters, it is guided by the guide rollers 6 on both sides of the lower part of the outer shell 1. The side rotating column 9 above the guide roller 6 supports the cooked strip. The dust removal parts on the outer surface of the side rotating column 9 remove the dust on the surface of the cooked strip. The first drive motor 13 starts and drives the bidirectional lead screw 7 to rotate. Since the ends of adjacent bidirectional lead screws 7 are connected by connecting rods 10, multiple bidirectional lead screws 7 rotate synchronously. The sliding blocks 8 on both sides of the outer surface of the bidirectional lead screw 7 move accordingly, thereby driving the side rotating column 9 to move to adapt to different specifications of cooked strip.

[0039] The dust removed by the dust removal components is sucked into the dust collection cylinder 14 by the exhaust fan 23, and then enters the dust collection box 17 for collection through the air outlet and filter components of the dust collection cylinder 14.

[0040] The first drive motor 13 drives the bidirectional lead screw 7 to rotate, and the connecting rod 10 makes multiple bidirectional lead screws 7 rotate synchronously, driving the sliding block 8 and the side rotating column 9 to move. The position of the side rotating column 9 can be adjusted according to different specifications of molten steel, which improves the applicability of the equipment.

[0041] Please see Figure 2 and Figure 6 Pulleys 11 are rotatably connected to both sides of the back of the outer casing 1, and the pulleys 11 are connected to the ends of the corresponding bidirectional lead screws 7. A transmission belt 12 is provided between the pulleys 11. When the bidirectional lead screw 7 rotates, the pulleys 11 connected to the ends of the bidirectional lead screw 7 rotate accordingly. Under the action of the transmission belt 12, the pulleys 11 on the other side rotate synchronously, thereby driving the corresponding bidirectional lead screw 7 to rotate synchronously. Through the cooperation of the pulleys 11 and the transmission belt 12, the synchronous rotation of the two bidirectional lead screws 7 can be achieved, ensuring the consistency and stability of the transmission and facilitating the coordinated work of related components.

[0042] Please see Figure 3 and Figure 6 The outer surface of the vacuum cleaner cylinder 14 is evenly provided with suction holes 15, and each of these holes is connected to a confluence pipe 16 at the air outlet of the vacuum cleaner cylinder 14. During the vacuuming process, dust enters the vacuum cleaner cylinder 14 through the evenly provided suction holes 15 on the outer surface of the vacuum cleaner cylinder 14, and then enters the confluence pipe 16 from the air outlet of the vacuum cleaner cylinder 14. The even distribution of the suction holes 15 makes the vacuuming range wider and the vacuuming effect more uniform. The confluence pipe 16 can collect the dust collected by multiple vacuum cleaner cylinders 14, which is convenient for subsequent centralized processing.

[0043] Please see Figure 2 , Figure 7 and Figure 8The outlet of the confluence pipe 16 is connected to the inlet of the dust collection box 17, and the dust collection box 17 is connected to the back of the outer casing 1. Dust collected in the confluence pipe 16 enters the inlet of the dust collection box 17 through its outlet and is ultimately stored inside the dust collection box 17. The dust collection box 17 is fixed in position through its connection to the back of the outer casing 1, achieving centralized dust storage. The connection between the dust collection box 17 and the outer casing 1 ensures the stability of the overall structure and facilitates unified dust treatment. Dust discharge troughs 18 are provided on both lower sides of the dust collection box 17, and a rotating shaft 19 is rotatably connected to the center of the inner cavity of the dust discharge trough 18. When dust stored in the dust collection box 17 needs to be discharged, it can be discharged through the dust discharge troughs 18 on both lower sides. The rotating shaft 19 rotates at the center of the inner cavity of the dust discharge trough 18, providing assistance for dust discharge. The dust discharge troughs 18 provide a channel for dust discharge, and the rotation of the rotating shaft 19 helps to promote dust discharge, making the dust discharge process smoother. A second drive motor 21 is mounted on both sides of the front and back of the dust collection box 17 via motor mounts, and the second drive motor 21 is coaxially connected to the end of the rotating shaft 19. When it is necessary to drive the rotating shaft 19 to rotate, the second drive motor 21 mounted on both sides of the front and back of the dust collection box 17 via motor mounts is started. The operation of the second drive motor 21 drives the end of the rotating shaft 19 coaxially connected to it to rotate, thereby causing the rotating shaft 19 to rotate as a whole. The second drive motor 21 provides a stable power source for the rotation of the rotating shaft 19, and the mounting method of the motor mounts ensures the stability of the second drive motor 21, ensuring that the rotating shaft 19 can operate reliably. Dust scraper plates 20 are installed on the upper and lower parts of the outer surface of the rotating shaft 19, and the outer surface of the dust scraper plates 20 slides against the inner wall of the dust discharge trough 18. When the rotating shaft 19 rotates, the dust scraper plates 20 installed on the upper and lower parts of its outer surface rotate together. The outer surface of the dust scraper plate 20 slides against the inner wall of the dust discharge trough 18, scraping the inner wall of the dust discharge trough 18 during rotation. The dust scraper plate 20 can promptly remove dust adhering to the inner wall of the dust discharge trough 18, preventing dust accumulation and blockage, and ensuring smooth dust discharge. At the same time, the dust scraper plate 20 and the dust discharge trough 18 work together to prevent gas from being discharged outside the dust collection box 17. A filter screen plate 22 is installed at the bottom of the inner cavity of the dust collection box 17. The filter screen plate 22 is designed with a high center and low ends. The outer surface of the dust scraper plate 20 slides against the upper surface of the filter screen plate 22 on both sides. After dust enters the dust collection box 17, it falls onto the filter screen plate 22 at the bottom of the inner cavity. The design of the filter screen plate 22, which is high in the center and low at both ends, causes the dust to accumulate on both sides. At the same time, when the dust scraper 20 rotates, its outer surface slides and adheres to both sides of the upper surface of the filter screen plate 22, scraping off the dust on the filter screen plate 22. The filter screen plate 22 can filter dust, and its design of high in the center and low at both ends facilitates dust accumulation. The scraping action of the dust scraper 20 can clean the dust on the filter screen plate 22 in time, prevent the filter screen plate 22 from clogging, and improve the dust collection efficiency of the dust collection box 17.

[0044] This solution: Start the roving frame for processing wool-polyester fabric sliver by controlling component 2;

[0045] The sliver of the wool-polyester fabric enters from the inlet and outlet 3 on both sides of the upper part of the outer shell 1. The side rollers 5 at both ends of the inlet and outlet 3 rotate to assist the sliver in entering. The elastic sleeve 4 on the inner wall of the inlet and outlet 3 protects the sliver.

[0046] After the cooked strip enters, it is guided by the guide rollers 6 at the lower part of both sides of the outer shell 1. The side rotating column 9 above the guide roller 6 supports the cooked strip, and the dust removal part on the outer surface of the side rotating column 9 removes the dust from the surface of the cooked strip.

[0047] The first drive motor 13 starts and drives the bidirectional lead screw 7 to rotate. Since the ends of adjacent bidirectional lead screws 7 are connected by connecting rods 10, multiple bidirectional lead screws 7 rotate synchronously. The sliding blocks 8 on both sides of the outer surface of the bidirectional lead screw 7 move accordingly, thereby driving the side rotating column 9 to move to adapt to different specifications of molten strips.

[0048] When the bidirectional lead screw 7 rotates, the pulley 11 connected to the end of the bidirectional lead screw 7 rotates accordingly. Under the action of the transmission belt 12, the pulley 11 on the other side rotates synchronously, thereby driving the corresponding bidirectional lead screw 7 to rotate synchronously.

[0049] The dust removed by the dust removal component enters the dust collection cylinder 14 through the dust collection holes 15 evenly opened on the outer surface of the dust collection cylinder 14 under the action of the exhaust fan 23, and then enters the confluence pipe 16 from the air outlet of the dust collection cylinder 14.

[0050] Dust collected in the confluence pipe 16 enters the inlet of the dust collection box 17 through its outlet end and is finally stored in the dust collection box 17. The dust collection box 17 is kept in a fixed position by its connection with the back of the outer shell 1.

[0051] After dust enters the dust collection box 17, it falls onto the filter screen 22 at the bottom of the inner cavity. The design of the filter screen 22, which is high in the center and low at both ends, causes the dust to gather on both sides.

[0052] When dust stored in the dust collection box 17 needs to be discharged, it is discharged through the dust discharge channels 18 opened on both sides at the bottom.

[0053] The second drive motor 21, which is mounted on both sides of the front and back of the dust collection box 17 via a motor mount, is started. The operation of the second drive motor 21 drives the end of the rotating shaft 19, which is coaxially connected to it, to rotate, thereby causing the rotating shaft 19 to rotate in the center of the inner cavity of the dust discharge trough 18.

[0054] When the rotating shaft 19 rotates, the dust scraper 20 installed on the upper and lower parts of its outer surface rotates together. The outer surface of the dust scraper 20 slides and adheres to the inner wall of the dust discharge trough 18 and the upper surface of the filter screen 22 on both sides, scraping the dust on the inner wall of the dust discharge trough 18 and the filter screen 22 during the rotation.
