Description

Technical Field

[0001] The invention relates to the technical field of circular knitting machines, in particular to a pressure-graded double-sided electronic circular knitting machine and a double-sided knitting process. Background Art

[0002] The pressure-graded double-sided electronic circular knitting machine is an advanced knitting equipment that combines pressure control and electronic technology. When knitting, the finished knitted fabrics can be designed with three pressure belts in the three core areas of waist and abdomen, buttocks, and legs according to the body changes and functional needs during pregnancy: U-shaped partition pressure design on the waist and abdomen, ring-shaped partition pressure design on the neck, and inverted triangle partition pressure design on the legs. These designs increase the support of the abdomen and back, tighten the false hips and relax the thighs, visually modify the legs and buttocks to make them look thinner and straighter, and strengthen core stability.

[0003] However, the existing circular knitting machines have a series of significant problems in actual operation. On the one hand, operators generally lack consideration for the weight of the bobbin with wire. The weight of the bobbin varies. During long-term use, an overweight bobbin will exert greater pressure on the support roller. Since the material and structural design of the existing support roller have limitations in bearing excessive loads, this can easily cause the support roller to deform. Once the support roller is deformed, first of all, the placement state of the bobbin will be unstable, and shaking and eccentricity will occur during the rotation process, which in turn causes uneven tension of the wire during transportation, sometimes too tight and sometimes too loose. Unstable tension not only affects the quality of knitted products, causing inconsistent fabric density and defects, but also causes wire breakage, increases downtime, and reduces production efficiency. Moreover, the deformed support roller will also aggravate the wear between the bobbin and the support roller, shorten the service life of the bobbin and the support roller, and increase production costs. More importantly, in the prior art, there is a lack of effective detection measures for whether the support roller is deformed. Operators can only realize that the support roller has been deformed after obvious product quality problems or equipment failures occur, which undoubtedly further aggravates production losses.

[0004] On the other hand, the installation level of the spandex rack is also extremely important for its normal operation and the stability of the entire knitting process. When installing the spandex rack, although it will be ensured to be installed horizontally in the initial stage, as the equipment runs for a long time and is affected by various factors such as vibration and collision in the workshop environment, the position of the spandex rack will gradually change, and its horizontal state is difficult to maintain for a long time; once the spandex rack loses its level, the force on the bobbin on the support roller will be uneven, resulting in the bobbin's unsmooth rotation, which will also cause tension fluctuations and instability during the wire conveying process; in addition, if the bobbin itself is deformed due to various reasons, such as being hit during transportation, or deformed due to its own quality problems during long-term use, then when it is placed on the support roller, it will further aggravate the instability of the entire device, seriously affecting the conveying effect of the knitting thread, and then negatively affecting the quality and production efficiency of the knitted products. However, in the prior art, there is a lack of effective monitoring and maintenance mechanisms for the changes in the horizontal position of the spandex rack and the deformation of the bobbin, which greatly restricts the improvement of the production efficiency and product quality of the double-sided electronic circular knitting machine.

[0005] Therefore, the present invention proposes a pressure-graded double-sided electronic circular knitting machine to solve the above problems. Summary of the invention

[0014] The double-sided knitting process of the double-sided electronic circular knitting machine as described above comprises the following steps: Yarn preparation, equipment commissioning and testing, looping process, fabric drawing and winding, appearance inspection; The yarn preparation comprises: Yarn selection: Select appropriate yarn bobbins according to the characteristics of the required fabric; Yarn pretreatment: some yarns need to be pretreated with wax or oil; The equipment debugging and testing includes: Adjustment of needle cylinder and needle disk: The double-sided electronic circular knitting machine has a needle disk and a lower needle cylinder, which are arranged perpendicular to each other. When installing the knitting needles, it is necessary to ensure that the knitting needles on the needle cylinder and the needle disk are arranged neatly, and the gap between the needles is uniform to ensure the accuracy of the knitting action; at the same time, adjust the relative position of the needle cylinder and the needle disk to ensure that the gap between the two meets the process requirements and avoid collision between the needles; Cam system adjustment: According to different knitting structures and patterns, the angle, height and position of the upper and lower cam seats can be precisely adjusted to change the movement trajectory of the knitting needles and achieve different knitting effects, such as plain stitch, rib, double rib, jacquard and other structures; Testing the bearing capacity of the support rollers and the deformation of the components; by observing whether the support rollers A and B move after the placement of the bobbin, and through the auxiliary feedback of the flow rate sensor in the connecting pipe, it can be known whether the support rollers are overloaded; and the movement of the offset angle indicator bar and the deformation scale rod is fed back through the scale to provide feedback on the installation level of the spandex rack and whether the bobbin is deformed; after all the above tests are completed and qualified, the subsequent work can be continued; The looping process comprises: When the knitting needle rotates to the cam action area with the needle cylinder or needle disk, the knitting needle rises or falls along the needle groove under the push of the cam; when rising, the knitting needle takes the old coil out of the needle hook, forming a loop-removing action; when falling, the new yarn is introduced into the needle hook to complete the yarn padding; as the needle cylinder and needle disk continue to rotate, the knitting needle further descends, the new yarn bends into a loop in the needle hook, and is intertwined with the old coil to complete the loop-removing and loop-forming process; the knitting needles of the upper and lower needle cylinders work together and cooperate with each other to form a double-sided fabric structure; The fabric pulling and winding includes: Pulling device: After the knitted fabric is output from the knitting machine, a certain tension is applied through the pulling device to pull the fabric downward to prevent the fabric from piling up around the needle cylinder and needle disc, which would affect the knitting process; Winding device: The pulled fabric is wound into a roll by the winding device. The winding speed and the size of the roll are adjusted according to the characteristics of the fabric and production requirements to ensure that the rolled fabric roll is tight and neat, which is convenient for subsequent transportation and processing; The appearance inspection includes: during the production process, the operator needs to regularly check the appearance quality of the fabric to see if there are any problems such as broken yarn, holes, missed stitches, pattern errors, and color differences. Once a problem is found, the machine should be stopped in time to investigate the cause; Physical properties testing: Sampling tests are conducted on the physical properties of fabrics, including fabric density, weight, elasticity, shrinkage, and color fastness indicators. The test data are compared with product standards. If any indicator is found to not meet the requirements, the knitting process parameters are adjusted in a timely manner to ensure that the product quality meets the standards.

[0015] Compared with the prior art, the present invention provides a pressure-graded double-sided electronic circular knitting machine, which has the following beneficial effects: 1. The present invention introduces an overload warning component that can detect the weight of the bobbin and warn of overload in the spandex frame system of the double-sided electronic circular knitting machine, which can significantly improve many problems in existing work and bring many beneficial effects: Protect the support roller and extend its service life: By monitoring the weight of the wire drum, the component can accurately determine whether the pressure on the support roller exceeds its load limit; once it detects that the weight of the wire drum will cause the support roller to be overloaded, it will promptly issue an early warning through the auxiliary display device; prevent the support roller from being deformed due to long-term excessive pressure, effectively extend the service life of the support roller, and reduce the cost of equipment maintenance and replacement; Stable wire conveying and improved product quality: Stable support roller state is the key to ensure smooth rotation of the bobbin and uniform wire conveying. This component prevents the bobbin from shaking and eccentricity caused by support roller deformation, so that the tension of the wire remains stable during the conveying process; this helps to eliminate the quality problems of inconsistent fabric density and defects caused by uneven tension, significantly improving the quality and consistency of knitted products and reducing the defective rate; Reduce downtime and improve production efficiency: Avoiding wire breakage and equipment failure caused by support roller deformation means that the number of downtimes in the production process is greatly reduced. The continuity of production is guaranteed, and workers do not need to frequently interrupt production to deal with wire breakage or equipment abnormalities, saving a lot of time and labor costs, greatly improving the production efficiency of the double-sided electronic circular knitting machine, and creating more economic benefits for the company.

[0016] 2. The present invention adjusts the control electromagnet to have different magnetic strengths through the overload warning component, thereby indirectly changing the flow resistance of the magnetorheological fluid in the connecting pipe associated with it, which can bring the following benefits: High adaptability and cost reduction: Operators can flexibly control the magnetic strength of the electromagnet according to actual usage. Since the electromagnet is interrelated with the magnetorheological fluid in the connecting tube, the change in magnetic strength can indirectly adjust the flow resistance of the magnetorheological fluid. This feature enables the overload warning component to cleverly adapt to support rollers of different sizes, diameters, lengths and wall thicknesses, as well as standard load-bearing capacity detection of various specifications of wire bobbins. There is no need to specially manufacture multiple types of detection devices for wire bobbins and support rollers A and B of different specifications, which greatly reduces the company's cost investment in equipment procurement and maintenance. At the same time, the wide adaptability means that when companies replace wire bobbins or support rollers of different specifications, there is no need for additional debugging or replacement of detection equipment, which significantly improves the versatility of the equipment and the flexibility of production, and further improves the company's production efficiency and economic benefits.

[0017] 3. The present invention can bring the following benefits to the overall work through the design of component standardization detection assembly: Ensure production stability: Through the effective detection of the installation level of the spandex rack, the change of its position can be detected in time; once the level is found to deviate from the standard, the operator can be quickly reminded to make adjustments to prevent uneven force and poor rotation of the bobbin due to the tilt of the spandex rack, ensure the stability of wire transportation, avoid frequent shutdowns caused by transportation problems, and maintain the continuity and efficiency of production; at the same time, the detection of bobbin deformation can detect the deformed bobbin at the first time and replace it in time to avoid its interference with the stability of the entire transportation system, further ensuring the smooth operation of the production process; Improve product quality: Stable wire delivery is the key to ensuring the quality of knitted products. Accurately detecting the horizontality of the spandex frame can avoid wire tension fluctuations caused by tilting, making the fabric density uniform and reducing the probability of defects; controlling the deformation of the wire bobbin can prevent abnormal wire delivery caused by deformed wire bobbins, thereby ensuring clear textures and accurate patterns of knitted products, significantly improving the appearance and internal quality of the products; Improve production efficiency: Standardized component detection components reduce production interruptions caused by spandex rack level problems and bobbin deformation; operators do not need to spend a lot of time troubleshooting and solving production stagnation caused by conveying problems, and can devote more energy to normal production, increase output per unit time, and give full play to the production potential of the equipment.

[0018] 4. The present invention can bring the following benefits to the component standardization detection work by using the offset angle indicator bar and the deformed scale rod through the component standardization detection assembly: Significantly improved operational convenience: With the help of the offset angle indicator bar, operators can visually observe the horizontality of the spandex rack. Without the need for complex measuring tools or professional calibration knowledge, operators can quickly determine whether the spandex rack is in a horizontal state by simply checking the offset degree of the offset angle indicator bar. Similarly, the offset angle indicator bar can directly display the deformation of the bobbin, and display the subtle deformation of the bobbin that was originally difficult to detect in the form of clear scales. This intuitive feedback method greatly simplifies the operator's daily inspection process of the equipment; Significantly optimized testing process: Under traditional testing methods, determining the horizontality of the spandex rack and the deformation of the bobbin requires cumbersome operations, such as using a level to measure the spandex rack and measuring the dimensions of the bobbin in all directions; the application of the offset angle indicator bar and the deformation scale bar makes the testing process clear at a glance, and the components of this assembly are in a stable installation state with the required testing parts. Different from the instability of manual testing, operators can quickly obtain key information, which not only saves manpower and time costs, but also reduces omissions caused by complex testing processes, making the testing work more efficient and accurate; Accelerate problem location and resolution: When there is a problem with the horizontality of the spandex rack or the bobbin is deformed, the operator can promptly detect the abnormality through the offset angle indicator bar and the deformation scale bar; this intuitive feedback helps to quickly locate the problem and avoid long-term troubleshooting due to the difficulty in detecting the problem; once the problem is identified, the operator can immediately take corresponding measures, effectively shortening the processing time of equipment failure, reducing the impact on production, and ensuring production continuity; Promote the normalization of equipment maintenance: Since detection becomes simple and convenient, operators are more willing to take the initiative to conduct daily inspections on the equipment. This helps to timely discover potential problems with the equipment, eliminate problems in the bud, and prevent small problems from turning into major failures; through normalized equipment maintenance, the overall performance of the equipment is better maintained, further extending the service life of the equipment and improving the reliability and stability of the equipment.

[0039] Further examples: The double-sided knitting process of the double-sided electronic circular knitting machine as described above comprises the following steps: Yarn preparation, equipment commissioning and testing, looping process, fabric drawing and winding, appearance inspection; Yarn preparation includes: Yarn selection: Select appropriate yarn bobbins according to the characteristics of the required fabric 4; Yarn pretreatment: some yarns need to be pretreated with wax or oil; Equipment debugging and testing include: Adjustment of needle cylinder and needle disk: The double-sided electronic circular knitting machine has a needle disk and a lower needle cylinder, which are arranged perpendicular to each other. When installing the knitting needles, it is necessary to ensure that the knitting needles on the needle cylinder and the needle disk are arranged neatly, and the gap between the needles is uniform to ensure the accuracy of the knitting action; at the same time, adjust the relative position of the needle cylinder and the needle disk to ensure that the gap between the two meets the process requirements and avoid collision between the needles; Cam system adjustment: According to different knitting structures and patterns, the angle, height and position of the upper and lower cam seats can be precisely adjusted to change the movement trajectory of the knitting needles and achieve different knitting effects, such as plain stitch, rib, double rib, jacquard and other structures; The bearing capacity of the support rollers and the deformation of the components are detected; by observing whether the support rollers A611 and B612 move after the placement of the bobbin 4, and through the auxiliary feedback of the flow rate sensor in the connecting pipe 608, it can be known whether the support rollers are overloaded; and the movement of the offset angle indicator bar 708 and the deformation scale rod 712 is fed back through the scale, so as to feedback the installation level of the spandex rack 3 and whether the bobbin 4 is deformed; after all the above tests are completed and qualified, the subsequent work can be continued; The looping process includes: When the knitting needle rotates to the cam action area with the needle cylinder or needle disk, the knitting needle rises or falls along the needle groove under the push of the cam; when rising, the knitting needle takes the old coil out of the needle hook, forming a loop-removing action; when falling, the new yarn is introduced into the needle hook to complete the yarn padding; as the needle cylinder and needle disk continue to rotate, the knitting needle further descends, the new yarn bends into a loop in the needle hook, and is intertwined with the old coil to complete the loop-removing and loop-forming process; the knitting needles of the upper and lower needle cylinders work together and cooperate with each other to form a double-sided fabric structure; Fabric pulling and winding include: Pulling device: After the knitted fabric is output from the knitting machine, a certain tension is applied by the pulling device to pull the fabric downward to prevent the fabric from piling up around the needle cylinder and the needle disc, which would affect the knitting process; Winding device: The pulled fabric is wound into a roll by the winding device. The winding speed and the size of the roll are adjusted according to the characteristics of the fabric and production requirements to ensure that the rolled fabric roll is tight and neat, which is convenient for subsequent transportation and processing; Appearance inspection includes: During the production process, operators need to regularly check the appearance quality of the fabric to see if there are any problems such as broken yarn, holes, missed stitches, pattern errors, and color differences. Once a problem is found, the machine should be stopped in time to investigate the cause; Physical properties testing: Sampling tests are conducted on the physical properties of fabrics, including fabric density, weight, elasticity, shrinkage, and color fastness indicators. The test data are compared with product standards. If any indicator is found to not meet the requirements, the knitting process parameters are adjusted in a timely manner to ensure that the product quality meets the standards.

[0040] Everything in the above example works like this: In the initial state: The first return spring 606 is not compressed, the electromagnet 609 is not energized, the outer expansion piece 715 is not clamped in the wire drum 4, the buckle cylinder 709 is not sleeved on the transmission roller, and the second return spring 707 and the third return spring 714 are in a normal relaxed state.

[0041] The following is the working process of the overload warning component 6: When in use, the operator energizes the electromagnet 609 through the control circuit, and then places the bobbin 4 on the support roller A611 and the support roller B612, so that the support roller A611 and the support roller B612 support the bobbin 4. Figure 6 At this time, the bobbin 4 will generate a component force on the support roller A611 and the support roller B612 under the action of its own gravity, and the support roller A611 and the support roller B612 will be in a certain extrusion state; Furthermore, since the working process of the overload warning assembly 6 on the support roller A611 and the support roller B612 when they are squeezed is similar, the following description is only based on the support roller A611. Figure 7When the support roller A611 is squeezed, there are two situations. First, the weight of the bobbin 4 meets the strength that the support roller A611 can bear. That is, at this time, the support roller A611 will not carry the sleeve 603 to make the sleeve 603 move with the guide rail 602 as the guide, and the first return spring 606 will not be compressed. Second, the weight of the bobbin 4 does not meet the strength that the support roller A611 can bear. At this time, the support roller A611 will carry the sleeve 603 to make the sleeve 603 move with the guide rail 602 as the guide. At this time, the first return spring 606 is compressed, and the sleeve 603 will move with the pushing piece 605 through the connecting piece 604. 05 During the movement in the overload feedback cavity 607, the magnetorheological fluid in the overload feedback cavity 607 will be squeezed to flow into the fluid storage element 610 through the connecting tube 608. Since a flow rate sensor is provided in the connecting tube 608, it is used to monitor the flow rate of the magnetorheological fluid in the connecting tube 608, so as to feedback the pressure state of the support roller at this time through an external display device with an electrical connection relationship; at this time, the flow rate sensor in the connecting tube 608 provides feedback to the corresponding personnel through the external display device with an electrical connection relationship, so as to inform that the weight of the bobbin 4 is greater than the force that the support roller group composed of the support roller A611 and the support roller B612 can withstand, and please replace it; Furthermore, by adjusting and controlling the electromagnet 609 to have different magnetic strengths through the overload warning component 6, the flow resistance of the magnetorheological fluid in the connecting pipe 608 associated with it is indirectly changed, which can be highly adaptable and reduce costs: the operator can flexibly control the magnetic strength of the electromagnet 609 according to actual usage; since the electromagnet 609 is interrelated with the magnetorheological fluid in the connecting pipe 608, the change in magnetic strength can indirectly adjust the flow resistance of the magnetorheological fluid; this feature enables the overload warning component 6 to cleverly adapt to support rollers of different sizes, diameters, lengths and wall thicknesses, as well as standard load-bearing capacity detection of various specifications of wire bobbins 4, without the need to specially manufacture multiple models of detection devices for wire bobbins 4 and support rollers A611 and B612 of different specifications, greatly reducing the company's cost investment in equipment procurement and maintenance; at the same time, the wide adaptability means that when the company replaces wire bobbins 4 or support rollers of different specifications, there is no need for additional debugging or replacement of detection equipment, which significantly improves the versatility of the equipment and the flexibility of production, and further improves the company's production efficiency and economic benefits.

[0042] Please refer to the above working process Figure 1 , Figure 2 , Figure 6 , Figure 7 .

[0043] The following is the working process of the component standardization detection component 7: Furthermore, after the overload warning component 6 has completed its detection work, the buckle cylinder 709 is sleeved on the support roller A611 and the support roller B612. Furthermore, the limit sleeve 702 sleeved on the auxiliary rod 701 will move under the action of the counterweight rod 703, that is, the counterweight rod 703 will be perpendicular to the ground under the action of its own gravity. Since the support roller A611 and the support roller B612 are arranged in parallel on the spandex frame 3, if the spandex frame 3 is installed horizontally, the horizontal plane where the support roller A611 and the support roller B612 are located should be perpendicular to the vertical line where the counterweight rod 703 and the limit rod 704 are located at this time. Please refer to the attached figure. Figure 3 , that is, at this time, the sliding indicator 706 on the sleeve A705 sleeved on the limit rod 704 will not move, that is, the sliding indicator 706 will not cause the second return spring 707 fixedly connected on both sides to be compressed; on the contrary, if the spandex rack 3 is loosened due to installation or use of the overall device and the installation level is offset, then at this time, the sleeve A705 will lead the sliding indicator 706 to change the relative position of the offset angle indicator bar 708, and the indicator needle on the sliding indicator 706 can feedback the horizontal deflection degree of the spandex rack 3 at this time, and the operator can perform corresponding maintenance operations accordingly; Furthermore, if the spandex frame 3 is in a horizontal installation state, under this premise, the outer expansion piece 715 can be clamped into the wire drum 4, as shown in the attached Figure 4 , at this time, the third return spring 714 in the piston cylinder 713 will be compressed. Since the deformation scale rod 712, the piston cylinder 713, the third return spring 714 and the outer expansion sheet 715 are a group, two groups are symmetrically arranged. When in use, the scales of the depth feedback of the deformation scale rod 712 in the two groups entering the piston cylinder 713 can be compared to determine whether the sleeve ring of the wire drum 4 is deformed at this time; if the scales of the depth feedback are consistent, deformation has occurred, otherwise, deformation has occurred; therefore, at this time, relevant personnel can determine whether the wire drum 4 is deformed at this time by observing the depth of the symmetrical deformation scale rod 712 inserted into the piston cylinder 713; if accurate detection is required, the above operation can be repeated multiple times; Furthermore, the component standardization detection assembly 7 can significantly improve the convenience of operation in component standardization detection work by using the offset angle indicator bar 708 and the deformation scale rod 712: with the help of the offset angle indicator bar 708, the operator can intuitively observe the horizontality of the spandex rack 3, without the need for complex measuring tools or professional calibration knowledge, and can quickly determine whether the spandex rack 3 is in a horizontal state by simply checking the offset degree of the offset angle indicator bar 708; similarly, the offset angle indicator bar 708 can directly present the deformation of the bobbin 4, and display the originally imperceptible subtle deformation of the bobbin 4 in the form of clear scales; this intuitive feedback method greatly simplifies the operator's daily inspection process of the equipment; Significantly optimize the inspection process: Under the traditional inspection method, determining the horizontality of the spandex frame 3 and the deformation of the bobbin 4 requires cumbersome operations, such as using a level to measure the spandex frame 3 and measuring the dimensions of the bobbin 4 in all directions; the application of the offset angle indicator bar 708 and the deformation scale bar 712 makes the inspection process clear at a glance, and the components of this assembly are in a stable installation state with the required inspection parts. Different from the instability of manual inspection, the operator can quickly obtain key information, which not only saves manpower and time costs, but also reduces omissions caused by the complexity of the inspection process, making the inspection work more efficient and accurate; Accelerate problem location and resolution: When the spandex rack 3 has a problem with its levelness or the bobbin 4 is deformed, the operator can promptly detect the abnormality through the offset angle indicator bar 708 and the deformation scale bar 712; this intuitive feedback helps to quickly locate the problem and avoid long-term troubleshooting due to the difficulty in detecting the problem; once the problem is identified, the operator can immediately take corresponding measures, effectively shortening the processing time of equipment failure, reducing the impact on production, and ensuring the continuity of production; Promote the normalization of equipment maintenance: Since detection becomes simple and convenient, operators are more willing to take the initiative to conduct daily inspections on the equipment. This helps to timely discover potential problems with the equipment, eliminate problems in the bud, and prevent small problems from turning into major failures; through normalized equipment maintenance, the overall performance of the equipment is better maintained, further extending the service life of the equipment and improving the reliability and stability of the equipment.
