Description

Technical Field

[0001] The invention relates to the technical field of textile processing equipment, and in particular to production equipment and method for high-elasticity warp knitted fabrics. Background Art

[0002] The finished fabric needs to be post-processed. Among them, the shearing machine is a device that can trim the fluff on the fabric and brush the trimmed fabric. The fabric treated by the shearing machine has better layering and ductility, which greatly improves the product quality of the finished fabric.

[0003] The prior art discloses an intelligent shearing machine and shearing process for easily curled fabrics, with publication number CN116289056A. The machine uses a beating roller to make the fluff on the surface of a specific fabric fluffy, and effectively cleans some floating hair and miscellaneous hair. The combing roller then raises the fluff in the same direction to facilitate contact between the fluff and the tool assembly, thereby ensuring the surface quality of the fabric after shearing.

[0004] Although it has the functions of beating and combing hair, there are still some defects in actual use. In the process of shearing and removing impurities for high-elasticity warp knitted fabrics, since the high-elasticity warp knitted fabrics are woven by multiple threads, some broken hairs are easy to fall into the gaps during the shearing process. However, the shearing machine only has the functions of beating and combing hairs, and is unable to stretch out the high-elasticity warp knitted fabrics, thereby being unable to completely beat out the stray hairs that fall into the gaps, causing the stray hairs and broken hairs to be sandwiched in the gaps, which the dust suction mechanism cannot suck out, thereby greatly reducing the cleaning effect of the device.

[0005] Therefore, a production equipment and method for high elasticity warp knitted fabrics are proposed to solve the above problems. Summary of the invention

[0015] In the above technical solution, further, a scale groove is provided on the side wall of the frame and located next to the lower travel switch, and a pointer is fixedly connected to the side wall of the lower travel switch.

[0016] A method for producing a high-elasticity warp knitted fabric is provided, using the above-mentioned production equipment for the high-elasticity warp knitted fabric, and the method steps are as follows:

[0017] Step 1: Let the fabric traction head pass through the tension adjustment mechanism, shearing mechanism, top roller, guide roller and fabric discharging mechanism in sequence, and set the timing controller to start the timing at the same time;

[0018] Step 2: Before use, adjust the stretching position according to the elasticity of the fabric. Turn the turntable to drive the threaded rod to rotate, which in turn drives the threaded sliding block to move. At the same time, observe the position of the pointer on the scale groove, accurately adjust the position of the lower travel switch, and then drive the lower travel switch to move, change the position of each pull-down reset, and then adjust the stretching length of the fabric;

[0019] Step 3: Then start the machine. When the high elastic performance warp knitted fabric is transported to the top roller after the shearing mechanism completes the shearing, the electric telescopic cylinder is controlled to start and drive the extrusion plate to slide downward. Since the inclined groove fits the inclined surface of the quadrilateral block, the downward movement of the extrusion plate will gradually squeeze the quadrilateral block to slide to both sides, and at the same time drive the guide block to move and compress the reset spring. At the same time, through the sliding of the quadrilateral block to both sides, the inclined surface of the quadrilateral block away from one side will gradually squeeze the roller downward, and then push the fixed seat, the push-down block and the clamping plate to slide downward, and at the same time compress the lower spring to clamp the fabric on the top roller;

[0020] Step 4: Then, the extrusion plate is driven by the electric telescopic cylinder to continue to slide downward, which will push the upper push block to slide downward, and slide the straight plate to the side of the quadrilateral block, and then push the upper push block and the extrusion roller to slide downward, so as to stretch the clamped high-elasticity warp knitted fabric from the middle downward. At the same time, when the extrusion plate drives the touch rod to slide downward, the extrusion of the upper stroke switch contact end will be lost, and then the upper stroke switch will transmit the signal to the controller, and the controller will control the vacuum cleaner to start, and at the same time control the cloth discharging mechanism to close, and through the transmission of the connecting pipe and the V-shaped pipe, the suction force is generated at the dust cover to absorb and clean the stray hair and broken hair on the stretched fabric;

[0021] Step 5: At the same time, the fabric will accumulate beside the top roller after coming out of the shearing mechanism. When the extrusion plate moves down and touches the lower stroke switch, the lower stroke switch transmits a signal to the controller, and the controller starts to control the electric telescopic cylinder to retract the telescopic cylinder, driving the extrusion plate to slide upward, and then repeats the above operation in the reverse direction;

[0022] Step 6: When the extrusion plate is reset and drives the touch rod to touch the upper stroke switch, the upper stroke switch will transmit the signal to the controller, the controller controls the electric telescopic cylinder to close and the timing controller to energize, and at the same time starts the cloth discharging mechanism to take away the fabric after cleaning, and at the same time transports the sheared and accumulated fabric between the top rollers. Then the timing controller reaches the set time, controls the electric telescopic cylinder to start and repeats the above operations.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Through the cooperation between the cleaning mechanism and the dust suction mechanism, during the cleaning process of the elastic warp knitted fabric after hair shearing, the fabric can be stretched out for cleaning, so that the stray hair that falls into the gap can be completely sucked out, thereby improving the cleaning effect of the device.

[0025] 2. Through the cooperation of the upper travel switch, threaded rod and sliding block, the distance of each pull-down can be adjusted according to the elasticity of different warp knitted fabrics, so it is suitable for warp knitted fabrics with different elasticity, which not only improves the cleaning effect of each fabric, but also increases the universal performance of the device.

A pair of top rollers 6 are rotatably connected inside the frame 1 and beside the shearing mechanism 5. A squeezing roller 7 is provided between the top rollers 6. An upper sliding groove 8 is opened on the side wall of the frame 1 at a position corresponding to the squeezing roller 7. Clamping plates 9 are provided above the top rollers 6. Lower sliding grooves 10 are opened on the side wall of the frame 1 at positions corresponding to the clamping plates 9. A cleaning mechanism for clamping and stretching the fabric is provided on the side wall of the frame 1. A vacuum cleaner 30 is fixedly connected to the side wall of the frame 1;

[0038] The cleaning mechanism includes an electric telescopic cylinder 11. A top plate 12 is fixedly connected to the inside of the frame 1. The electric telescopic cylinder 11 is fixedly connected to the top of the top plate 12. An upper pushing block 13 is fixedly connected to the side wall of the squeezing roller 7 and is slidably connected to the inside of the upper sliding groove 8. Lower pushing blocks 14 are fixedly connected to the side walls of the clamping plates 9 and are slidably connected to the inside of the lower sliding groove 10. A dust suction mechanism is provided inside the frame 1 and below the top roller 6. Fixed seats 15 are fixedly connected to the tops of the lower pushing blocks 14. Quadrilateral blocks 16 with inclined sides on both sides are longitudinally slidably connected to the side walls of the frame 1 and above the fixed seats 15. The output end of the electric telescopic cylinder 11 passes through the top plate 12 and is fixedly connected to a pressing plate 17. Oblique grooves 18 that fit the inclined surfaces of the quadrilateral blocks 16 are provided on both sides of the pressing plate 17. A roller 19 is rotatably connected to the inside of the fixed seat 15 and fits the top end of the inclined surface of the quadrilateral block 16. Upper springs 20 are fixedly connected between the inside of the upper sliding groove 8 and the upper pushing block 13. Lower springs 21 are fixedly connected between the inside of the lower sliding groove 10 and the bottoms of the lower pushing blocks 14. Straight plates 42 are fixedly connected to both sides of the top of the pressing plate 17;

[0039] The dust suction mechanism includes a V-shaped plate 31. The V-shaped plate 31 is fixedly connected to the inside of the frame 1 and below the top roller 6. A plurality of dust suction covers 32 are fixedly connected to the inside of the V-shaped plate 31, and the openings of the plurality of dust suction covers 32 are arranged on the side close to each other. A plurality of V-shaped pipes 33 are fixedly connected to the bottom of the V-shaped plate 31. The plurality of V-shaped pipes 33 are all communicated with the dust suction covers 32. A connecting pipe 34 communicated with the V-shaped pipes 33 is fixedly connected to the side wall of the V-shaped plate 31. The end of the connecting pipe 34 is fixedly connected to the dust suction end of the vacuum cleaner 30;

[0040] In order to guide the sliding of the quadrilateral block 16, guiding grooves 22 that are recessed are provided on the side walls of the frame 1 at positions corresponding to the quadrilateral block 16. Guiding blocks 23 are fixedly connected to the side walls of the quadrilateral block 16 and are slidably connected to the inside of the guiding grooves 22. A return spring 24 is fixedly connected between the inside of the guiding grooves 22 and the side walls of the guiding blocks 23. Through the arrangement of the guiding grooves 22 and the guiding blocks 23, the sliding of the quadrilateral block 16 can be guided, avoiding the random movement of the quadrilateral block 16 and affecting the normal operation of the cleaning mechanism.

[0041] In order to improve the stability during the fabric conveying process, a guiding roller 25 is rotatably connected to the inside of the frame 1 and below the fabric outlet mechanism 4. The clamping plates 9 are arranged in an arc shape adapted to the outer wall of the top roller 6. Through the arrangement of the guiding roller 25, the conveyed fabric after cleaning can be guided, avoiding directly conveying it upward to the fabric outlet mechanism 4 and causing the phenomenon that the fabric is squeezed by the clamping plates 9.

[0042] In order to improve the degree of automation of the device, a timing controller 26 is fixedly connected to the side wall of the frame 1, a touch rod 27 is fixedly connected to the side wall of the extrusion plate 17, an upper travel switch 28 is fixedly connected to the side wall of the frame 1 and is located next to the touch rod 27, and a lower travel switch 29 is provided on the side wall of the frame 1 and is located below the extrusion plate 17. The upper travel switch 28 and the lower travel switch 29 are electrically connected to the timing controller 26, the electric telescopic cylinder 11, the cloth discharging mechanism 4 and the vacuum cleaner 30 through the controller. By setting the timing controller 26, the upper travel switch 28 and the lower travel switch 29, the operation of the cleaning mechanism can be automatically controlled to improve the automation efficiency of the device.

[0043] When the high elastic warp knitted fabric is transported to the top roller 6 after the shearing is completed by the shearing mechanism 5, the electric telescopic cylinder 11 is controlled to start and drive the extrusion plate 17 to slide downward. Since the inclined groove 18 fits the inclined surface of the quadrilateral block 16, the downward movement of the extrusion plate 17 will gradually squeeze the quadrilateral block 16 to slide to both sides, and at the same time drive the guide block 23 to move the compressed reset spring 24. At the same time, through the sliding of the quadrilateral block 16 to both sides, the inclined surface of the quadrilateral block 16 away from one side will gradually squeeze the roller 19 downward, thereby pushing the fixed seat 15, the push-down block 14 and the clamping plate 9 to slide downward, and at the same time compressing the lower spring 21 to clamp the fabric on the top roller 6;

[0044] Then, the squeezing plate 17 is driven by the electric telescopic cylinder 11 to continue to slide downward, which will push the upper push block 13 to slide downward, and at the same time, the straight plate 42 will slide to the side of the quadrilateral block 16, and then the upper push block 13 and the squeezing roller 7 will be pushed downward to stretch the clamped high elasticity warp knitted fabric from the middle downward. At the same time, when the squeezing plate 17 drives the touch rod 27 to slide downward, the squeezing of the contact end of the upper stroke switch 28 will be lost, and then the upper stroke switch 28 will transmit the signal to the controller, and the controller controls the vacuum cleaner 30 to start, and at the same time controls the cloth discharging mechanism 4 to close, and through the transmission of the connecting pipe 34 and the V-shaped pipe 33, suction is generated at the dust hood 32 to absorb and clean the stray hair and broken hair on the stretched fabric.

[0045] In order to be able to adjust the distance of each pull-down according to the elasticity of different warp knitted fabrics, an inward adjustment groove 35 is opened on the side wall of the frame 1 and located next to the lower travel switch 29, a threaded rod 36 is rotatably connected to the inner side of the adjustment groove 35, and a sliding block 37 is threadedly connected to the outer wall of the threaded rod 36, and the sliding block 37 is fixedly connected to the side wall of the lower travel switch 29, and a through groove 41 is opened through the side wall of the frame 1 and located below the adjustment groove 35, and a turntable 38 is fixedly connected to the inner side of the through groove 41 through the bottom of the threaded rod 36, and a scale groove 39 is opened on the side wall of the frame 1 and located next to the lower travel switch 29, and a pointer 40 is fixedly connected to the side wall of the lower travel switch 29;

[0046] By rotating the turntable 38, the threaded rod 36 is driven to rotate, and then the slidable block 37 connected by threads is driven to move. At the same time, observe the position of the pointer 40 on the scale groove 39, accurately adjust the position of the lower travel switch 29, and then drive the lower travel switch 29 to move, changing the position of each pull-down reset, so as to adjust the stretching length of the fabric, and thus be applicable to warp knitted fabrics with different elasticities, not only improving the cleaning effect of each fabric, but also increasing the general performance of the device.

[0047] A production method of a warp knitted fabric with high elastic performance uses the above-mentioned production equipment for a warp knitted fabric with high elastic performance. The method steps are as follows:

[0048] Step 1: Pass the fabric traction head through the tension adjusting mechanism 3, the shearing mechanism 5, the top roller 6, the guiding roller 25 and the fabric outlet mechanism 4 in sequence, and at the same time set the timing controller 26 to start the timing.

[0049] Step 2: Before use, adjust the stretching position according to the elasticity of the fabric. By rotating the turntable 38, the threaded rod 36 is driven to rotate, and then the slidable block 37 connected by threads is driven to move. At the same time, observe the position of the pointer 40 on the scale groove 39, accurately adjust the position of the lower travel switch 29, and then drive the lower travel switch 29 to move, changing the position of each pull-down reset, so as to adjust the stretching length of the fabric.

[0050] Step 3: Then start the machine. When the warp knitted fabric with high elastic performance is conveyed towards the top roller 6 after being sheared by the shearing mechanism 5, control the electric telescopic cylinder 11 to start and drive the pressing plate 17 to slide downward. Since the inclined groove 18 is in contact with the inclined surface of the quadrilateral block 16, when the pressing plate 17 moves downward, the quadrilateral block 16 will be gradually squeezed to slide to both sides, and at the same time drive the guiding block 23 to move and compress the return spring 24. At the same time, due to the sliding of the quadrilateral block 16 to both sides, the inclined surface on the side where the quadrilateral block 16 is away from each other will gradually press down on the roller 19, thereby pushing the fixed seat 15, the lower pushing block 14 and the clamping plate 9 to slide downward, and at the same time compressing the lower spring 21 to clamp the fabric on the top roller 6.

[0051] Step 4: Then, the squeezing plate 17 is driven by the electric telescopic cylinder 11 to continue to slide downward, which will push the upper push block 13 to slide downward, and at the same time, the straight plate 42 will slide to the side of the quadrilateral block 16, and then the upper push block 13 and the squeezing roller 7 will be pushed downward to stretch the clamped high elasticity warp knitted fabric from the middle downward. At the same time, when the squeezing plate 17 drives the touch rod 27 to slide downward, the squeezing of the contact end of the upper stroke switch 28 will be lost, and then the upper stroke switch 28 will transmit the signal to the controller, and the controller controls the vacuum cleaner 30 to start, and at the same time controls the cloth discharging mechanism 4 to close, and through the transmission of the connecting pipe 34 and the V-shaped pipe 33, the dust cover 32 generates suction, and the stray hair and broken hair on the stretched fabric are adsorbed and cleaned;

[0052] Step 5: At the same time, the fabric will be accumulated beside the top roller 6 after coming out of the shearing mechanism 5. When the squeezing plate 17 moves down and touches the lower stroke switch 29, the lower stroke switch 29 transmits a signal to the controller, and the controller starts to control the electric telescopic cylinder 11 to retract the telescopic cylinder, driving the squeezing plate 17 to slide upward, and then repeats the above operation in the reverse direction;

[0053] Step six: When the squeezing plate 17 is reset and drives the touch rod 27 to touch the upper travel switch 28, the upper travel switch 28 will transmit a signal to the controller, and the controller controls the electric telescopic cylinder 11 to close and controls the timing controller 26 to be energized, and at the same time starts the cloth discharging mechanism 4 to take away the fabric after cleaning, and at the same time transports the sheared and accumulated fabric to between the top rollers 6. Then the timing controller 26 reaches the set time, and controls the electric telescopic cylinder 11 to start and repeat the above operations repeatedly.

7. A method for producing a high-elasticity warp knitted fabric, using the production equipment for a high-elasticity warp knitted fabric according to claim 6, the method steps are as follows: Step 1: The fabric pulling head is passed through the tension adjustment mechanism (3), the shearing mechanism (5), the top roller (6), the guide roller (25) and the fabric discharging mechanism (4) in sequence, and the timing controller (26) is set to start the timing; Step 2: Before use, the stretching position is adjusted according to the elasticity of the fabric, the threaded rod (36) is driven to rotate by turning the turntable (38), and the threaded sliding block (37) is driven to move, and the position of the pointer (40) on the scale groove (39) is observed at the same time, and the position of the lower travel switch (29) is accurately adjusted, thereby driving the lower travel switch (29) to move, changing the position of each pull-down reset, and thereby adjusting the stretching length of the fabric; Step 3: Then, the machine is started. When the high elastic performance warp knitted fabric passes through the shearing mechanism (5) and is transported toward the top roller (6) after shearing, the electric telescopic cylinder (11) is controlled to start and drive the squeezing plate (17) to slide downward. Since the inclined groove (18) fits the inclined surface of the quadrilateral block (16), the squeezing plate (17) moves downward, and the quadrilateral block (16) is gradually squeezed to slide to both sides, and the guide block (23) is driven to move and compress the return spring (24). At the same time, the quadrilateral block (16) slides to both sides, and the inclined surface of the quadrilateral block (16) away from one side gradually squeezes the roller (19) downward, thereby pushing the fixed seat (15), the push-down block (14) and the clamping plate (9) to slide downward, and compressing the lower spring (21) to clamp the fabric on the top roller (6); Step 4: Then, the squeezing plate (17) is driven by the electric telescopic cylinder (11) to continue to slide downward, which will push the upper push block (13) to slide downward, and at the same time, the straight plate (42) is slid to the side of the quadrilateral block (16), and then the upper push block (13) and the squeezing roller (7) are pushed downward to stretch the clamped high elasticity warp knitted fabric from the middle downward. At the same time, when the squeezing plate (17) drives the touch rod (27) to slide downward, the squeezing of the contact end of the upper travel switch (28) is lost, and then the upper travel switch (28) transmits a signal to the controller, and the controller controls the vacuum cleaner (30) to start, and at the same time controls the cloth discharging mechanism (4) to close, and through the transmission of the connecting pipe (34) and the V-shaped pipe (33), suction is generated at the dust cover (32), and the stray hair and broken hair on the stretched fabric are adsorbed and cleaned; Step 5: At the same time, the fabric will be accumulated beside the top roller (6) after coming out of the shearing mechanism (5). When the squeezing plate (17) moves downward and touches the lower travel switch (29), the lower travel switch (29) transmits a signal to the controller, and the controller starts to control the electric telescopic cylinder (11) to retract the telescopic cylinder, driving the squeezing plate (17) to slide upward, and then repeating steps 3 to 5; Step 6: When the squeezing plate (17) is reset and drives the touch rod (27) to touch the upper travel switch (28), the upper travel switch (28) transmits a signal to the controller, and the controller controls the electric telescopic cylinder (11) to close and controls the timing controller (26) to energize, and at the same time starts the cloth discharging mechanism (4) to take away the fabric after cleaning, and at the same time transports the sheared and accumulated fabric to the top roller (6). Then, when the timing controller (26) reaches the set time, it controls the electric telescopic cylinder (11) to start and repeat the operation of steps 3 to 6.
