Description

Technical Field

[0001] This invention relates to the field of warping machine technology, and in particular to a warp knitting slitting and copying warping machine and its production method. Background Technology

[0002] A warping machine is a mechanical device used to arrange warp yarns. It helps to draw a limited amount of yarn from the spindle or bobbin, arrange it, and then feed it into the loom head to complete the weaving of fabrics of different specifications and shapes. It mainly includes yarn arrangement, weft control, weft guiding, yarn feeding, transmission, and control. The warping machine is an important component of the loom and an indispensable piece of equipment in textile production. It can improve the efficiency and quality of textile production.

[0003] The warp knitting slitting copy warping machine is a new type of high-efficiency warping machine. It has a unique head-rolling process. It only needs to use dozens of yarn packages and adopt the method of slitting and splicing to produce head rolls of the same length and length as traditional slitting warping machines. It has the characteristics of saving raw materials, saving costs, fast product turnover, short production cycle and economic practicality.

[0004] When using a warping machine, an empty warp beam needs to be installed. In order to fix the empty warp beam in place by the clamps on both sides, the position of the empty warp beam needs to be adjusted manually and repeatedly, which increases the labor intensity and reduces the installation efficiency. Summary of the Invention

[0005] This invention discloses a warp knitting slitting and copying warp machine and its production method, aiming to solve the technical problems in the background art that require repeated manual adjustment of the position of the empty warp beam, which increases labor intensity and results in low installation efficiency.

[0006] The present invention proposes a warp knitting slitting and copying warp machine, comprising a machine housing, side seats on both sides of the machine housing, slide seats on both side seats, and the side seats being movably connected to the machine housing. Clamping plates are movably connected to both side seats, and multiple circumferentially equidistant retaining protrusions are fixedly connected to opposite sides of the two clamping plates. An empty warp beam is disposed between the two clamping plates. The empty warp beam consists of two side rings and two tail rings, with the two tail rings symmetrically distributed at both ends of the empty warp beam and the two side rings symmetrically distributed between the two tail rings. Multiple circumferentially equidistant retaining grooves are formed on both tail rings, and a warp beam feeding assembly is disposed between the two side seats.

[0007] By setting up a housing, side seat, clamp, retaining protrusion, empty warp beam, side ring, tail ring, retaining groove, and warp beam feeding assembly, the clamp and empty warp beam are used as matching equipment. That is, the retaining protrusion of the clamp corresponds and fits with the retaining groove on the tail ring. The warp beam feeding assembly is used to assist in the feeding operation of the empty warp beam, which can realize the flipping feeding and positioning of the empty warp beam, thereby realizing the quick retention of the empty warp beam by the clamp. The mechanical method replaces the manual auxiliary transfer operation during the installation of the empty warp beam, reducing the labor intensity of workers and improving the installation efficiency of the empty warp beam.

[0008] In a preferred embodiment, the warp beam feeding assembly includes two support arms, each located below two side rings. Each support arm has a displacement groove, which fits into the opening of the groove. A limit block is movably connected inside the displacement groove. A first hydraulic cylinder is fixedly connected to each support arm, with its extension / retraction end fixedly connected to the limit block on the same side. Each support arm also has a rectangular slide groove, inside which an inner moving plate is movably connected. A slide groove is formed on the upper side of the inner moving plate, and a positioning frame is movably connected inside the slide groove. The positioning frame is located outside the tail ring, and a positioning spring is fixedly connected to the side of the positioning frame away from the support arm. The other end of the positioning spring is fixedly connected to the inner moving plate. The positioning frame is semi-circular, and two symmetrical positioning protrusions are fixedly connected to the positioning frame. The positioning protrusions fit into the retaining groove. A rectangular mounting hole is opened on the side of the support arm away from the positioning frame. An electric push rod is fixedly connected inside the rectangular mounting hole. The other end of the electric push rod is fixedly connected to the inner moving plate. Both support arms are provided with round holes. A flip motor is fixedly connected to one side of the chassis. The output end of the flip motor is connected to a flip shaft through a coupling. The other end of the flip shaft passes through the round holes of the two support arms and is movably connected to the inner wall of the other side of the chassis. The outside of the flip shaft is fixedly connected to the round holes of the support arms.

[0009] The assembly includes a warp beam feeding system. This system utilizes two flip-type support arms to lift and feed empty warp beams. A movable positioning frame and positioning protrusions are used to position the empty warp beams, ensuring that the retaining groove of the tail ring on the lifted empty warp beam corresponds to the retaining protrusion of the clamping plate. This facilitates the quick positioning and installation of the empty warp beams by the clamping plate, improving the overall installation efficiency. A limit block restricts the placement of the empty warp beams, ensuring they are in the correct installation position after flipping. The first hydraulic cylinder adjusts the position of the limit block to prevent inaccurate positioning after flipping due to differences in the specifications of some empty warp beams.

[0010] In a preferred embodiment, a traction wheel is fixedly connected to the side of one of the clamps away from the empty warp shaft, and a drive motor is fixedly connected to the side seat on the same side. The output end of the drive motor is connected to a short shaft via a coupling, and the other end of the short shaft is fixedly connected to a drive wheel. A belt is provided between the drive wheel and the traction wheel. A shift seat is fixedly connected to the upper side of the slide of each of the two side seats. The shift seats have threaded holes, and the inner wall threads of the threaded holes on the two shift seats are in opposite directions. The inside of the threaded holes on the two shift seats is rotatably connected to the same lead screw via the inner wall threads. The two ends of the lead screw are movably connected to the inner walls of the two sides of the machine housing, respectively. A motor base is fixedly connected to the bottom inner wall of the machine housing, and an adjusting motor is fixedly connected to the motor base. The output end of the adjusting motor is connected to a rotating shaft via a coupling, and the other end of the rotating shaft is fixedly connected to a drive gear. An adjusting gear is fixedly connected to the outside of the lead screw, and the adjusting gear and the drive gear are meshed through tooth grooves.

[0011] In a preferred embodiment, the upper side of the chassis is provided with a cover, and the cover is provided with two symmetrical flip arms. The two flip arms are movably connected to the outer walls of the two sides of the chassis, and the cover is provided with multiple observation windows, each of which is made of tempered glass.

[0012] In a preferred embodiment, the machine cover is provided with a uniformity self-testing component; the uniformity self-testing component includes a self-testing frame and an outer indicator plate. The self-testing frame is located inside the machine cover, and a front plate is fixedly connected to the side of the self-testing frame away from the machine cover. Two symmetrical second hydraulic cylinders are fixedly connected to the inner wall of the machine cover near the self-testing frame, and the other ends of the two second hydraulic cylinders are fixedly connected to the self-testing frame. The outer indicator plate is located on the outside of the machine cover and is fixedly connected to the machine cover. Multiple equidistant warning lights are provided on the outer indicator plate; the front plate... The device has multiple equidistant circular holes, each with a connecting rod movably connected inside. A self-test head is fixedly connected to the end of the connecting rod away from the self-test frame, and a test cylinder is movably connected to each self-test head. The other end of the connecting rod is located between the self-test frame and the front plate. A gasket is provided on the outside of the connecting rod. The self-test frame has multiple equidistant rectangular mounting slots, each with a pressure sensor fixedly connected inside. A return spring is sleeved on the outside of the connecting rod, and both ends of the return spring are fixedly connected to the gasket and the corresponding pressure sensor's force-bearing end, respectively.

[0013] By incorporating a uniformity self-inspection component, the component uses a detection cylinder to contact the yarn outside the empty warp beam and monitors whether the winding of the yarn outside the empty warp beam is uniform based on data fed back by a pressure sensor. If the yarn is too thick or too thin, a warning light will be activated to prompt personnel to make timely adjustments, thereby improving the overall yarn winding effect of the device.

[0014] A method of using a warp knitting slitting and copying warp machine, comprising the following steps:

[0015] Step 1: The yarn installation operation sequence is as follows: place the yarn on the device, move the empty warp beam to the front of the machine box, and use the warp beam feeding assembly to position the empty warp beam and then flip it over to feed the yarn.

[0016] Step 2: Start the adjusting motor to adjust the position of the two side seats so that the two clamps hold and fix the empty warp beam. Then the warp beam feeding assembly is reset, and the yarn is wound and fixed on the outside of the empty warp beam.

[0017] Step 3: After closing the machine cover, adjust the position of the uniformity self-inspection component. With the uniformity self-inspection component in operation, start the drive motor. The empty warp beam rotates with the chuck to perform the warping operation of the yarn.

[0018] As can be seen from the above, the warp knitting slitting and copying warp machine provided by the present invention has a clamping plate and an empty warp beam as supporting equipment. That is, the fixing protrusion of the clamping plate corresponds and fits with the fixing groove on the tail ring. The empty warp beam is fed by the warp beam feeding assembly, which can realize the flipping feeding and positioning of the empty warp beam, thereby realizing the quick fixing of the empty warp beam by the clamping plate. The mechanical method replaces the manual auxiliary transfer operation during the installation of the empty warp beam, reducing the labor intensity of workers and improving the installation efficiency of the empty warp beam.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The warp knitting slitting and copying warp machine disclosed in this invention is mainly used in scenarios where the installation efficiency of empty warp beams is low.

[0029] Reference Figure 1-7 A warp knitting slitting and copying warp machine includes a machine housing 1. Side seats 2 are provided on both sides of the machine housing 1. Slide seats are provided on each side seat 2. The side seats 2 are slidably connected to the machine housing 1. Clamping plates 3 are rotatably connected to each side seat 2 via bearings. Multiple circumferentially spaced retaining protrusions 4 are bolted to the opposite side of each clamping plate 3. An empty warp beam 5 is provided between the two clamping plates 3. The empty warp beam 5 consists of two side rings 6 and two tail rings 7. The two tail rings 7 are symmetrically distributed at both ends of the empty warp beam 5. The two side rings 6 are symmetrically distributed between the two tail rings 7. Multiple circumferentially spaced retaining grooves 8 are provided on each tail ring 7. A warp beam feeding assembly 9 is provided between the two side seats 2.

[0030] Specifically, the yarn installation operation sequence is as follows: the empty warp beam 5 is moved to the front of the machine housing 1, and the empty warp beam 5 is positioned and flipped for loading using the warp beam loading assembly 9. The clamping plate 3 and the empty warp beam 5 are a matching device, that is, the fixing protrusion 4 of the clamping plate 3 corresponds and fits with the fixing groove 8 on the tail ring 7. The loading of the empty warp beam 5 is assisted by the warp beam loading assembly 9, which can realize the flipping loading and positioning of the empty warp beam 5, thereby realizing the quick fixing of the empty warp beam 5 by the clamping plate 3. The mechanical operation replaces the manual auxiliary transfer operation during the installation of the empty warp beam 5, reducing the labor intensity of workers and improving the installation efficiency of the empty warp beam 5.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The shaft feeding assembly 9 includes two support arms 901, which are located below two side rings 6. Each support arm 901 has a displacement groove 902, which fits into the opening of the side ring 6. A limit block 903 is slidably connected inside the displacement groove 902. A first hydraulic cylinder 904 is bolted to each support arm 901, and the extension / retraction end of the first hydraulic cylinder 904 is bolted to the limit block 903 on the same side. Each support arm 901 has a rectangular sliding groove, inside which an inner moving plate 908 is slidably connected. A sliding groove is formed on the upper side of the inner moving plate 908, and a positioning frame 905 is slidably connected inside the sliding groove. The positioning frame 905 is located outside the tail ring 7. A positioning spring 909 is bolted to the side of the positioning frame 905 away from the support arm 901. The other end of the positioning spring 909... The inner moving plate 908 is connected by bolts. The positioning frame 905 is semi-circular. Two symmetrical positioning protrusions 906 are bolted to the positioning frame 905. The positioning protrusions 906 fit into the fixing groove 8. A rectangular mounting hole is opened on the side of the support arm 901 away from the positioning frame 905. An electric push rod 907 is bolted to the inside of the rectangular mounting hole. The other end of the electric push rod 907 is bolted to the inner moving plate 908. Both support arms 901 have round holes. A flip motor 911 is bolted to one side of the housing 1. The output end of the flip motor 911 is connected to a flip shaft 910 through a coupling. The other end of the flip shaft 910 passes through the round holes of the two support arms 901 and is rotatably connected to the inner wall of the other side of the housing 1 through bearings. The outside of the flip shaft 910 is bolted to the round holes of the support arm 901.

[0032] Specifically, the empty warp beam 5 is moved to the front of the housing 1 and pushed forward. The two side rings 6 enter the shifting slots 902 of the two support arms 901 respectively. The front end of the side ring 6 contacts the limiting block 903. The flipping motor 911 starts and drives the flipping shaft 910 to rotate 30°, then pauses. The electric push rods 907 on the two support arms 901 start to retract synchronously. The inner shift plate 908 shifts, the positioning frame 905 moves towards the tail ring 7, and the positioning protrusion 906 contacts and presses against the tail ring 7. The positioning spring 909 is compressed. The electric push rod 907 retracts to the predetermined position and stops. At this time, the empty warp beam 5 is rotated, and the tail ring 7 rotates accordingly. When the positioning protrusion 906 reaches the fixed position... Under the elastic force of the positioning spring 909, the positioning frame 905 moves towards the tail ring 7, and the positioning protrusion 906 is inserted into the fixing groove 8 to achieve the positioning of the empty warp shaft 5. Then, the flip motor 911 continues to start, causing the empty warp shaft 5 to be raised to the installation position, that is, between the two clamping plates 3. During the fixing process of the clamping plates 3 on the empty warp shaft 5, the two clamping plates 3 move towards the empty warp shaft 5 simultaneously, the fixing protrusion 4 is inserted into the fixing groove 8, the positioning protrusion 906 is moved out, and the positioning frame 905 is offset away from the tail ring 7 to achieve the installation and fixing of the empty warp shaft 5. Then, the flip motor 911 reverses to drive the support arm 901 to move down and reset, and at the same time, the electric push rod 907 extends to drive the inner moving plate 908 to reset.

[0033] In specific application scenarios, the warp beam feeding assembly 9 is suitable for the installation of empty warp beams 5. The warp beam feeding assembly 9 uses two flip-type support arms 901 to lift and feed the empty warp beams 5. The movable positioning frame 905 and the positioning protrusion 906 can be used to position the empty warp beams 5, so that the fixing groove 8 of the tail ring 7 on the lifted empty warp beams 5 can correspond to the fixing protrusion 4 of the clamping plate 3. This facilitates the quick positioning and installation of the empty warp beams 5 by the clamping plate and improves the overall installation efficiency of the empty warp beams 5. The limiting block 903 can limit the empty warp beams 5 after they are placed, so that the empty warp beams 5 can be in the correct installation position after flipping. The first hydraulic cylinder 904 can adjust the position of the limiting block 903 to avoid inaccurate positioning after flipping due to different specifications of some empty warp beams 5.

[0034] Reference Figure 1 , Figure 2 and Figure 5On one of the clamping plates 3, a traction wheel 10 is bolted to the side away from the empty warp shaft 5, and a drive motor 11 is bolted to the side seat 2 on the same side. The output end of the drive motor 11 is connected to a short shaft via a coupling, and the other end of the short shaft is bolted to a drive wheel 12. A belt is installed between the drive wheel 12 and the traction wheel 10. A shifting seat 13 is bolted to the upper side of the slide of each of the two side seats 2. Each shifting seat 13 has a threaded hole, and the inner threads of the two shifting seats 13 are in opposite directions. The same lead screw 14 is rotatably connected to the threaded hole on the seat 13 through the inner wall thread. The two ends of the lead screw 14 are rotatably connected to the inner walls of the two sides of the housing 1 through bearings. The bottom inner wall of the housing 1 is bolted to a motor base. An adjusting motor 16 is bolted to the motor base. The output end of the adjusting motor 16 is connected to a rotating shaft through a coupling. The other end of the rotating shaft is bolted to a drive gear 17. An adjusting gear 15 is bolted to the outside of the lead screw 14. The adjusting gear 15 and the drive gear 17 are meshed through tooth grooves.

[0035] Specifically, during the fixing of the chuck 3 to the empty warp beam 5, the adjusting motor 16 rotates, driving the drive gear 17 to mesh with the adjusting gear 15, the lead screw 14 rotates, and the two shift seats 13 are forced to move the two side seats 2 closer to each other; during the warping process, the drive motor 11 is started, the drive wheel 12 uses a belt to drive the traction wheel 10 to rotate, the two chucks 3 rotate synchronously, and the empty warp beam 5 performs the warping operation of the yarn along with the rotation of the chuck 3;

[0036] Reference Figure 1 and Figure 6 The upper side of the chassis 1 is provided with a cover 18. The cover 18 is provided with two symmetrical flip arms. The two flip arms are rotatably connected to the outer walls of the two sides of the chassis 1 through bearings. The cover 18 is provided with multiple observation windows 19, and each of the multiple observation windows 19 is provided with tempered glass.

[0037] Specifically, during the entire production line process, the cover 18 is in a closed state, and the status of the entire line can be monitored in real time through the observation window 19. The cover 18 can effectively prevent accidental contact by personnel during the entire production line process, create a semi-enclosed space, and improve the self-cleaning and safety of the entire line.

[0038] Reference Figure 1 , Figure 6 and Figure 7The machine cover 18 is equipped with a uniformity self-testing component 20. The uniformity self-testing component 20 includes a self-testing frame 2001 and an outer indicator plate 2002. The self-testing frame 2001 is located inside the machine cover 18. A front plate 2003 is bolted to the side of the self-testing frame 2001 away from the machine cover 18. Two symmetrical second hydraulic cylinders 2009 are bolted to the inner wall of the side of the machine cover 18 closest to the self-testing frame 2001. The other ends of the two second hydraulic cylinders 2009 are bolted to the self-testing frame 2001. The outer indicator plate 2002 is located on the outside of the machine cover 18 and is bolted to the machine cover 18. Multiple equidistant warning lights 2010 are provided on the outer indicator plate 2002. The front plate 2003 has... Multiple equidistant circular holes are provided, and connecting rods 2006 are slidably connected inside each hole. One end of each connecting rod 2006 away from the self-test frame 2001 is bolted to a self-test head 2004. A test cylinder 2005 is rotatably connected to each self-test head 2004 via a bearing. The other end of the connecting rod 2006 is located between the self-test frame 2001 and the front plate 2003. A gasket is provided on the outside of the connecting rod 2006. Multiple equidistant rectangular mounting slots are provided on the self-test frame 2001. Pressure sensors 2008 are bolted inside each rectangular mounting slot. A return spring 2007 is sleeved on the outside of each connecting rod 2006. The two ends of the return spring 2007 are bolted to the gasket and the corresponding force-bearing end of the pressure sensor 2008, respectively.

[0039] Specifically, after the cover 18 is closed, the second hydraulic cylinder 2009 adjusts the position of the self-testing frame 2001, bringing it closer to the empty warp beam 5 until the detection cylinder 2005 contacts the yarn outside the empty warp beam 5. The pressure sensor 2008 feeds back a pressure signal. Once the pressure signal reaches the preset value, the second hydraulic cylinder 2009 stops automatically, and all warning lights 2010 are turned off. During the entire production process, if a local area has excessively thick or thin yarn, the pressure sensor 2008 will feed back the value to the panel, and the corresponding warning light 2010 will turn on, illuminating red to prompt personnel to make timely adjustments. It should be noted that the data changes received by the pressure sensor 2008 during the entire production process will be directly fed back to the panel. When the overall pressure value reaches the preset critical value, the second hydraulic cylinder 2009 will be controlled to contract, meaning that the extension and retraction of the second hydraulic cylinder 2009 changes with the amount of yarn outside the empty warp beam 5.

[0040] In specific application scenarios, the uniformity self-inspection component 20 is suitable for monitoring the yarn outside the empty warp beam 5 during the whole line process. That is, the uniformity self-inspection component 20 uses the detection cylinder 2005 to contact the yarn outside the empty warp beam 5, and monitors whether the winding of the yarn outside the empty warp beam 5 is uniform by the data fed back by the pressure sensor 2008. When the yarn is too thick or too thin, the warning light 2010 is turned on to prompt the personnel to make timely adjustments, thereby improving the overall whole line effect of the device.

[0041] A method of using a warp knitting slitting and copying warp machine, comprising the following steps:

[0042] Step 1: Yarn Installation Operation Sequence. Place the empty warp beam 5 on the device and move it to the front of the machine housing 1. After positioning the empty warp beam 5 using the warp beam feeding assembly 9, flip it to feed (push the empty warp beam 5 to move it forward, and the two side rings 6 respectively enter the shifting grooves 902 of the two support arms 901, with the front end of the side ring 6 contacting the limit block 903). The flipping motor 911 starts, driving the flipping shaft 910 to rotate 30°, and then pauses. The electric push rods 907 on the two support arms 901 start synchronously to feed the yarn. As the warp retracts, the inner moving plate 908 shifts, the positioning frame 905 moves towards the tail ring 7, the positioning protrusion 906 contacts and presses against the tail ring 7, the positioning spring 909 is compressed, and the electric push rod 907 retracts to the predetermined position and stops. At this time, the hollow warp shaft 5 is rotated, and the tail ring 7 rotates accordingly. When the positioning protrusion 906 reaches the fixing groove 8, it is subjected to the elastic force of the positioning spring 909, the positioning frame 905 moves towards the tail ring 7, and the positioning protrusion 906 is inserted into the fixing groove 8, thus realizing the positioning of the hollow warp shaft 5.

[0043] Step 2: Start the adjusting motor 16 to adjust the position of the two side seats 2 so that the two clamping plates 3 clamp and fix the empty warp beam 5 (after the empty warp beam 5 is raised to the installation position, that is, between the two clamping plates 3, during the process of clamping the empty warp beam 5, the two clamping plates 3 move closer to the empty warp beam 5 at the same time, the fixing protrusion 4 is inserted into the fixing groove 8, the positioning protrusion 906 is moved out, and the positioning frame 905 is offset away from the tail ring 7 to realize the installation and fixation of the empty warp beam 5). Then the warp beam feeding assembly 9 is reset and the yarn is wound and fixed on the outside of the empty warp beam 5.

[0044] Step 3: After closing the machine cover 18, adjust the position of the uniformity self-test component 20. The uniformity self-test component 20 is in operation (using the second hydraulic cylinder 2009 to adjust the position of the self-test frame 2001, making it move closer to the empty warp beam 5 until the detection cylinder 2005 contacts the yarn outside the empty warp beam 5, the pressure sensor 2008 feeds back a pressure signal, and the second hydraulic cylinder 2009 stops automatically when the pressure signal reaches the preset value, and all warning lights 2010 are in the off state; during the whole line process, when there is a local yarn that is too thick or too thin, the pressure sensor The device 2008 will feed back the numerical status to the panel, and the corresponding warning light 2010 will be on, with a red light indicating that the personnel should make timely adjustments. It should be noted that the data changes received by the pressure sensor 2008 during the entire production line will be directly fed back to the panel. When the overall pressure value reaches the preset critical value, the second hydraulic cylinder 2009 will be adjusted to contract (that is, the extension and retraction state of the second hydraulic cylinder 2009 changes with the amount of yarn outside the empty warp beam 5), and the drive motor 11 will be started. The empty warp beam 5 will rotate with the clamp 3 to perform the warping operation of the yarn.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
