Description

Technical Field

[0001] The present invention relates to the technical field of knitting, and particularly to a knitting device and process for carpet roving yarns. Background Art

[0002] When producing and processing carpets, roving yarns are required. The knitting of roving yarns usually requires a roving frame. The models of roving frames include FA420, FA422, and Jingwei JWF1415. A roving frame is a spinning machine that makes fiber strips into roving yarns. The main functions of a roving frame are drafting and twisting, and winding the roving into a certain package.

[0003] According to the application number: CN201811402646.7, a roving frame for acrylic yarns, comprising a fixed bottom plate, on the top of which a lower dragon beam is fixedly installed, a cotton bale cylinder fixedly installed on the top of the fixed bottom plate and located on the right side of the lower dragon beam, and a support plate fixedly installed on the top of the fixed bottom plate and located between the lower dragon beam and the cotton bale cylinder.

[0004] When making yarns from multiple fibers by the roving frame in the above case, it is inconvenient to remove dust and broken flocs on the surface of the yarn, which seriously affects the cleanliness and smoothness of the yarn surface and reduces the production quality. Some devices use the cooperation of a suction fan and a filter screen to handle the dust and broken flocs on the surface of the yarn, such as the application number: CN201821472412.5, a roving frame for yarns.

[0005] When the filter screen in the above case becomes blocked, it affects the effect of dust removal and broken floc removal. At this time, it is necessary to stop the machine to replace the filter screen, which seriously affects the efficiency of dust removal and broken floc removal for the yarn. Therefore, we provide a knitting device and process for carpet roving yarns. Summary of the Invention

On the top of the frame, four wire columns are installed, and a wool fiber yarn bobbin, a nylon fiber yarn bobbin, a hemp fiber yarn bobbin, and a polyester fiber yarn bobbin are respectively sleeved on the four wire columns. At the bottom of the inner wall of the fixed frame and on the right side of the cleaning shell, a treatment shell is installed.

[0008] Preferably, it further includes a high-pressure blower, which is installed on the left side of the cleaning shell. On the right side of the high-pressure blower, a blowing pipe communicated with it is installed, and the right end of the blowing pipe penetrates through the cleaning shell and extends into its interior.

[0009] Preferably, a high-voltage power generator is installed on the left side of the cleaning shell, and an electrode body for discharging, which is used in cooperation with the high-voltage power generator, is installed on the left side of the inner wall of the cleaning shell. Two support blocks are installed at the bottom of the inner wall of the cleaning shell, and the two support blocks are fixedly connected by an annular frame. Cleaning brushes are installed on both the left and right sides of the inner wall of the annular frame.

[0010] Preferably, a fixed pipe is installed at the bottom of the high-pressure blower. One end of the fixed pipe away from the high-pressure blower penetrates through the processing shell and extends into its interior. A first hose is installed at the top end of the fixed pipe. The front and rear sides of the inner wall of the processing shell are fixedly connected by a partition plate, and filter nets are arranged on both the left and right sides of the partition plate.

[0011] Preferably, air guide covers are arranged at both the top and bottom of the left filter net. The air guide cover at the bottom and close to the first hose is connected to the first hose. The air guide cover at the top and away from the filter net is provided with a second hose. One end of the second hose away from the filter net is installed with an air suction pipe. The left end of the air suction pipe penetrates through the cleaning shell and extends into its interior. A sealing plate for cooperating with the partition plate is installed on the surface of the air guide cover.

[0012] Preferably, connection blocks are installed on both the left and right sides of the inner wall of the processing shell. Gas flow sensors are installed on the connection blocks. Top blocks are installed on both the left and right sides of the inner wall of the processing shell and on both the left and right sides of the partition plate. Sealing doors are rotatably connected to both the left and right sides of the front of the processing shell through hinges, and alarms are installed on the sealing doors.

[0013] Preferably, a servo motor is installed on the right side of the inner wall of the fixed frame. A threaded rod is installed at the left end of the output shaft of the servo motor. A moving plate is threadedly connected to the surface of the threaded rod. An adjusting block is installed on the left side of the moving plate and corresponding to the position of the air guide cover. The left side of the adjusting block is fixedly connected to the right side of the air guide cover.

[0014] Preferably, four guide rollers are installed on the top of the frame. Four first twisting wheels are installed on the top of the inner wall of the frame. Two second twisting wheels are installed on the top of the fixed frame. Two conducting rollers are installed on the back of the inner wall of the fixed frame.

[0015] Preferably, a winding assembly is arranged at the bottom of the fixed frame. A limit cap is threadedly connected to the top end of the thread post.

[0016] A knitting process for carpet roving yarn specifically includes the following steps:

[0017] S1. Raw material preparation: Prepare a certain amount of wool fibers, nylon fibers, hemp fibers, and polyester fibers, then wind them onto bobbins. Then place the wool fiber bobbin, nylon fiber bobbin, hemp fiber bobbin, and polyester fiber bobbin onto the thread posts, and then rotate the limit caps onto the thread posts;

[0018] S2. Fiber processing and impurity removal: The fibers pass through the guide rollers, the first twisting wheel, the second twisting wheel, and the conduction roller in sequence and enter the cleaning shell, so that the fibers are twisted into roving yarns. Start the high-pressure blower and the static eliminator. The static eliminator is a high-voltage power generator and a discharge electrode body, which removes the broken flocs and dust on the yarns, sucks them into the processing shell through the suction pipe, filters and intercepts the dust and broken flocs through the filter screen, and the yarns are further cleaned by the cleaning brush and then wound on the winding assembly;

[0019] S3. Making carpets: Export the roving yarns wound on the winding assembly and enter the shuttle loom equipment. The roving yarns are woven into carpets through warp and weft. After weaving, the carpets need to be trimmed and sorted to remove the excess threads to make the carpet surface smoother and more even.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. By starting the high-pressure blower, the high-voltage power generator, and the discharge electrode body, the present invention enables the discharge electrode body to generate high-voltage corona discharge to ionize the air into a large number of positive and negative ions, and then blows a large number of positive and negative ions onto the surface of the yarns to neutralize the static electricity, so that the dust and broken flocs on the yarns fall off, and at the same time, the static electricity is eliminated. The dust and broken flocs are filtered and intercepted through the filter screen. The gas flow sensor senses the gas flow passing through the corresponding filter screen. When the filter screen is blocked, the gas flow decreases, triggering the corresponding alarm to remind the staff to disassemble and clean the filter screen.

[0022] 2. The present invention drives the air guide cover to move left and right through the servo motor. When one filter screen is blocked, the air guide cover moves to another filter screen, and the dust and broken flocs on the yarns are continuously filtered and intercepted through the other filter screen, avoiding affecting the efficiency of dust removal and broken floc removal of the yarns, enabling it to work continuously. The cleaning brush can further process the dust and broken flocs on the surface of the yarns, improving the processing effect, thereby improving the cleanliness and smoothness of the yarn surface and the production quality.

[0023] 3. By setting up the wool fiber bobbin, the softness, elasticity, warmth retention and moisture absorption of the carpet made of the yarn are improved. By setting up the nylon fiber bobbin, the wear resistance, resilience and easy cleaning effect of the carpet made of the yarn are improved. By setting up the hemp fiber bobbin, the toughness, elasticity and insect-proof and mildew-proof effects of the carpet made of the yarn are improved. By setting up the polyester fiber bobbin, the wear resistance, wrinkle resistance and stain resistance of the carpet made of the yarn are improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1-8 , a knitting device for carpet roving, including a frame 1 and a fixed frame 2 installed on the inner wall of the frame 1. The front of the fixed frame 2 is in an open state. The bottom of the inner wall of the fixed frame 2 is fixedly connected with a cleaning shell 3. Four wire columns 4 are fixedly connected to the top of the frame 1. A wool fiber bobbin 5, a nylon fiber bobbin 6, a hemp fiber bobbin 7 and a polyester fiber bobbin 8 are respectively sleeved on the four wire columns 4. A processing shell 9 is fixedly connected to the bottom of the inner wall of the fixed frame 2 and on the right side of the cleaning shell 3.

[0035] Furthermore, a microcomputer is fixedly connected to the left side of the frame 1.

[0036] It further includes a high-pressure blower 10. The high-pressure blower 10 is installed on the left side of the cleaning shell 3. The right side of the high-pressure blower 10 is fixedly connected with a blowing pipe 11 communicating with it. The right end of the blowing pipe 11 penetrates through the cleaning shell 3 and extends into its interior. A high-voltage power generator 12 is fixedly connected to the left side of the cleaning shell 3. An electrode body 13 cooperating with the high-voltage power generator 12 is fixedly connected to the left side of the inner wall of the cleaning shell 3. The electrode body 13 is made in the shape of an ion needle, and air is ionized into a large number of positive and negative ions through the high-voltage corona discharge at the tip. The high-voltage power generator 12 and the electrode body 13 are combined into an electrostatic eliminator. Two support blocks 14 are fixedly connected to the bottom of the inner wall of the cleaning shell 3. The two support blocks 14 are fixedly connected through an annular frame 15. Cleaning brushes 16 are fixedly connected to both the left and right sides of the inner wall of the annular frame 15.

[0037] A fixed pipe 17 is fixedly connected to the bottom of the high-pressure blower 10. One end of the fixed pipe 17 away from the high-pressure blower 10 penetrates through the processing shell 9 and extends into its interior. A first hose 20 is fixedly connected to the top end of the fixed pipe 17. The front and rear sides of the inner wall of the processing shell 9 are fixedly connected through a partition plate 21. Filter nets 22 are arranged on both the left and right sides of the partition plate 21. The surface of the filter net 22 is in contact with the inner wall of the processing shell 9. One side of the filter net 22 close to the partition plate 21 is in contact with the partition plate 21. Air guide covers 23 are arranged at both the top and bottom of the left filter net 22. The air guide cover 23 at the bottom and close to the first hose 20 is connected to the first hose 20. The air guide cover 23 at the top and away from the filter net 22 is fixedly connected to a second hose 24. The lengths of the first hose 20 and the second hose 24 are relatively long and will not affect the movement of the air guide cover 23. One end of the second hose 24 away from the filter net 22 is fixedly connected to an air suction pipe 25. The left end of the air suction pipe 25 penetrates through the cleaning shell 3 and extends into its interior. The air suction pipe 25 is fixedly connected to the right side of the inner wall of the cleaning shell 3 through a reinforcing block. By setting the reinforcing block, the stability of the air suction pipe 25 in the cleaning shell 3 is improved. A sealing plate 200 used in cooperation with the partition plate 21 is fixedly connected to the surface of the air guide cover 23. The surface of the sealing plate 200 is in contact with the inner wall of the processing shell 9. One side of the sealing plate 200 close to the partition plate 21 is in contact with the partition plate 21. By setting the sealing plate 200, the sealing performance of the air guide cover 23 is improved, and it is avoided that gas leaks in the processing shell 9 and affects the blowing and suction effects.

[0038] Connecting blocks 26 are fixedly connected to both the left and right sides of the inner wall of the processing shell 9. A gas flow sensor 27 is fixedly connected to the connecting block 26. Top blocks 28 are fixedly connected to both the left and right sides of the inner wall of the processing shell 9 and the left and right sides of the partition plate 21. The top of the top block 28 is in contact with the bottom of the filter net 22. By setting the top block 28, the effect of supporting the filter net 22 is achieved. Sealing doors 29 are rotatably connected to both the left and right sides of the front of the processing shell 9 through hinges. An alarm 30 is fixedly connected to the sealing door 29. A servo motor 31 is fixedly connected to the right side of the inner wall of the fixed frame 2. The left end of the output shaft of the servo motor 31 is fixedly connected to a threaded rod 32. A moving plate 33 is threadedly connected to the surface of the threaded rod 32. An adjusting block 34 is fixedly connected to the left side of the moving plate 33 at a position corresponding to the air guide cover 23. The left side of the adjusting block 34 is fixedly connected to the right side of the air guide cover 23.

[0039] Furthermore, since the surface of the sealing plate 200 is always in contact with the inner wall of the processing shell 9, the stability of the moving plate 33 driving the air guide cover 23 to move to the right through the adjusting block 34 is ensured.

[0040] Specifically, when it is necessary to remove the left filter net 22, open the sealing door 29, and then pull the filter net 22 forward, and the left filter net 22 can be pulled out of the processing shell 9.

[0041] By starting the high-pressure blower 10, the high-voltage power generator 12 and the discharge electrode body 13, the discharge electrode body 13 conducts high-voltage corona discharge to ionize the air into a large number of positive and negative ions, and then blows a large number of positive and negative ions to the surface of the yarn to neutralize static electricity, causing the dust and broken flocs on the yarn to fall off, and at the same time achieving the effect of eliminating static electricity. The dust and broken flocs are filtered and intercepted by the filter screen 22. The gas flow sensor 27 senses the gas flow passing through the corresponding filter screen 22. When the filter screen 22 is blocked, the gas flow decreases, triggering the corresponding alarm 30 to remind the staff to disassemble and clean the filter screen 22.

[0042] The air guide cover 23 is driven by the servo motor 31 to move left and right. When one filter screen 22 is blocked, the air guide cover 23 moves to another filter screen 22, and the dust and broken flocs of the yarn are continuously filtered and intercepted by the other filter screen 22, avoiding affecting the efficiency of dust removal and broken floc removal of the yarn, enabling it to work continuously. The cleaning brush 16 can further process the dust and broken flocs on the surface of the yarn, improving the treatment effect, thereby improving the cleanliness and smoothness of the yarn surface and the production quality.

[0043] Four guide rollers 35 are fixedly connected to the top of the frame 1. Four first twisting wheels 36 are fixedly connected to the top of the inner wall of the frame 1. Two second twisting wheels 37 are fixedly connected to the top of the fixed frame 2. Two conduction rollers 38 are fixedly connected to the back of the inner wall of the fixed frame 2. A winding assembly 39 is arranged at the bottom of the fixed frame 2. The top end of the thread post 4 is threadedly connected with a limit cap 40. By setting the limit cap 40, the stability of the bobbin 5 on the thread post 4 is ensured, avoiding the phenomenon of detachment.

[0044] Furthermore, the winding assembly 39 includes mounting plates 391. The number of the mounting plates 391 is two and they are respectively mounted at the bottom of the fixed frame 2. A rotating motor 392 is fixedly connected to the left mounting plate 391. The right end of the output shaft of the rotating motor 392 penetrates through the left mounting plate 391 and extends to its outside. A winding drum 393 is fixedly connected to the surface of the output shaft of the rotating motor 392.

[0045] Furthermore, the high-pressure blower 10, the high-voltage power generator 12, the discharge electrode body 13, the gas flow sensor 27, the alarm 30, the servo motor 31 and the rotating motor 392 are respectively electrically connected to the microcomputer, and the control circuit can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the art and will not be elaborated here too much.

[0046] By setting up the wool fiber bobbin 5, the softness, good elasticity, warmth retention and moisture absorption of the carpet made of the yarn are improved. By setting up the nylon fiber bobbin 6, the wear resistance, resilience and easy cleaning effect of the carpet made of the yarn are improved. By setting up the hemp fiber bobbin 7, the toughness, elasticity and insect and mildew prevention effect of the carpet made of the yarn are improved. By setting up the polyester fiber bobbin 8, the wear resistance, wrinkle resistance and stain resistance of the carpet made of the yarn are improved.

[0047] A weaving process for carpet rovings specifically includes the following steps:

[0048] S1. Raw material preparation: Prepare a certain amount of wool fiber, nylon fiber, hemp fiber and polyester fiber, then wind them on bobbins, then place the wool fiber bobbin 5, nylon fiber bobbin 6, hemp fiber bobbin 7 and polyester fiber bobbin 8 on the thread post 4, and then rotate the limit cap 40 onto the thread post 4;

[0049] S2. Fiber processing and impurity removal: The fibers pass through the guide roller 35, the first twisting wheel 36, the second twisting wheel 37 and the conduction roller 38 in sequence and enter the cleaning shell 3, so that the fibers are twisted into rovings. Start the high-pressure blower 10 and the static eliminator. The static eliminator is a high-voltage power generator 12 and a discharge electrode body 13, which removes the broken flocs and dust on the yarn, sucks them into the treatment shell 9 through the suction pipe 25, filters and intercepts the dust and broken flocs through the filter screen 22, and the yarn is then cleaned by the cleaning brush 16 and then wound on the winding assembly 39;

[0050] S3. Carpet making: Export the rovings wound on the winding assembly 39 and enter the shuttle loom equipment. The model of the shuttle loom is GA615F. The rovings are woven into a carpet through warp and weft. After weaving, the carpet needs to be trimmed and sorted to remove the redundant threads to make the carpet surface smoother and more even.

[0051] During use, the wool fiber bobbin 5, nylon fiber bobbin 6, hemp fiber bobbin 7 and polyester fiber bobbin 8 are placed on the thread post 4, and then the limit cap 40 is rotated onto the thread post 4. The fibers pass through the guide roller 35, the first twisting wheel 36, the second twisting wheel 37 and the conduction roller 38 in sequence and enter the cleaning shell 3. At this time, the fibers are twisted into rovings;

[0052] Start the high-pressure blower 10 and the static eliminator. The static eliminator is a high-voltage power generator 12 and a discharge electrode body 13. Blow air onto the yarn through the air blowing pipe 11. Cooperating with the static eliminator, the broken flocs and dust on the yarn can be effectively removed. When the dust particles pass through the electrostatic field, they are adsorbed onto the electrode under the action of the electric field force to achieve the dust removal effect;

[0053] Meanwhile, since the high-pressure blower 10 is started, suction force is generated in the suction pipe 25, and dust and broken flocs are discharged into the processing shell 9 through the suction pipe 25 and the air guide cover 23 located at the top, and are filtered and intercepted by the filter screen 22 located on the left side. The gas then enters the first hose 20 through the air guide cover 23 located at the bottom, and the gas is transmitted to the high-pressure blower 10 again through the fixed pipe 17 and then discharged through the blow pipe 11;

[0054] The gas flow sensor 27 senses the gas flow passing through the filter screen 22 on the left side. When the gas flow is lower than the set value, a signal is sent to the microcomputer, and the microcomputer then starts the alarm 30 located on the left side to sound an alarm, reminding the staff that the filter screen 22 on the left side needs to be disassembled and cleaned. At the same time, the servo motor 31 is started. The servo motor 31 drives the threaded rod 32 to rotate through the output shaft. The threaded rod 32 drives the adjustment block 34 to move to the right through the moving plate 33. The adjustment block 34 drives the air guide cover 23 to move to the right. The air guide cover 23 drives the sealing plate 200 to move to the right, so that the sealing plate 200 is in close contact with the right side of the inner wall of the processing shell 9. The two air guide covers 23 move to the positions corresponding to the filter screen 22 on the right side, and then the dust and broken flocs are filtered and intercepted by the filter screen 22 on the right side;

[0055] The yarn is further cleaned by the cleaning brush 16 and then wound around the winding drum 393. The rotating motor 392 is started, and the rotating motor 392 drives the winding drum 393 to rotate, so as to wind the woven yarn.

[0056] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

Fiber processing and impurity removal: The fibers pass through the guide rollers (35), first twisting wheels (36), second twisting wheels (37), and conduction rollers (38) in sequence and enter the cleaning shell (3), so that the fibers are twisted into roving. Start the high-pressure blower (10) and the static eliminator. The static eliminator is a high-voltage power generator (12) and a discharge electrode body (13), which removes broken flocs and dust on the yarn. The yarn is sucked into the processing shell (9) through the suction pipe (25), and the dust and broken flocs are filtered and intercepted by the filter screen (22). The yarn is then cleaned by the cleaning brush (16) and then wound on the winding assembly (39). S3. Carpet making: The roving wound on the winding assembly (39) is led out and enters the weaving machine equipment. The roving is woven into a carpet through warp and weft. After weaving, the carpet needs to be trimmed and sorted to remove the excess threads to make the carpet surface smoother and more even.
