Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of textile machinery, and particularly relates to an antibacterial and deodorizing polyester fiber knitted mattress fabric production device and method. BACKGROUND

[0002] In order to improve the comfort, air permeability and supportability of the knitted mattress fabric, the knitted mattress fabric is usually composed of multiple layers of sub-fabrics with different functions.

[0003] The outermost layer of the mattress fabric is usually made of polyester (polyester fiber) through the warp knitting or weft knitting process, has high elasticity and is usually provided with air holes. The middle layer of the mattress fabric is usually made of 3D mesh and sponge, the 3D mesh has a three-dimensional structure and can play the functions of support and air permeability, and the sponge can increase the softness of the mattress fabric. In some mattress fabrics, a natural latex thin layer or a silver ion antibacterial fabric layer is added to the middle layer to improve the fabric resilience and play the effect of inhibiting bacteria and mites. The inner layer of the mattress fabric is usually made of high-density non-woven fabric to enhance the stability of the fabric structure and prevent the displacement of the filler.

[0004] In the current mattress fabric production process, the layers of sub-fabrics constituting the mattress fabric are first flattened and then stacked in order, and finally the layers of sub-fabrics are sewn together by a quilting machine, and finally a rhombic or regular hexagonal grid pattern is formed on the surface of the mattress fabric.

[0005] In practice, the inventors found that the air permeability and supportability of the mattress fabric made according to the above process method often do not reach the theoretical simulation effect. Through research, it was found that the potential reason is that because the layers of textile fabrics constituting the mattress fabric have different stretchability, the deformation amount generated by each layer of sub-fabric when stretched is not uniform. For example, when a user lies on the mattress, the mattress will be pressed downward, thereby causing a stretching effect on the mattress fabric. At this time, the sub-fabric with air holes in the mattress fabric originally has air holes, and the size of the air holes may be narrowed or even completely closed due to stretching, such as shown in FIG. 1, a piece of elastic fabric with rhombic air holes gradually becomes smaller after being stretched, thereby reducing the air permeability of the mattress during use. In some special layer structures and material combinations, the air permeability of the mattress fabric is also reduced due to the staggered blocking of the air holes between adjacent layers. Figure 1

[0006] It can be seen that how to solve the above problems is the key to improving the quality of the mattress fabric, and is also a technical difficulty that needs to be overcome at present. SUMMARY

DETAILED DESCRIPTION

[0027] Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings.

[0028] In the description of the present specification, the description of the terms "certain embodiments", "one embodiment", "some embodiments", "illustrative embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the described embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0029] An antibacterial deodorant fiber polyester knitted mattress fabric production device, as shown in the figure, comprises a frame 100, a sewing machine head 200 and a feeding system 300. Figure 1

[0030] The above-mentioned sewing machine head 200 comprises a plurality of sewing needles 211 arranged on the support crossbar 210, so as to simultaneously sew multiple layers of sub-fabrics.

[0031] The feeding system 300 comprises a flattening roller 311 group 310, a tensioning roller 321 group 320 and a laminating roller 331 group 330. The flattening roller 311 group 310 comprises a plurality of flattening rollers 311 rotatably arranged between the two side frames 100 through bearings 103, for flattening each layer of sub-fabric to remove wrinkles of the sub-fabric. The laminating roller 331 group 330 comprises at least one laminating roller 331 rotatably arranged between the two side frames 100, and the multiple layers of sub-fabrics are laminated together at the laminating roller 331 and then conveyed to below the sewing needle 211 for sewing.

[0032] Compared with the prior art, the improvement is that the tensioning roller 321 group 320 comprises a plurality of tensioning rollers 321 rotatably arranged between the two side frames 100 through bearings 103, and each tensioning roller 321 corresponds to a layer of sub-fabric, for tensioning each layer of sub-fabric to be sewn according to different stretching forces.

[0033] Further improvement is that the adjustment assembly is used to adjust the stretching state of each layer of sub-fabric during sewing, that is, when the stretching state of one layer of sub-fabric changes, the stretching state of the adjacent layer of sub-fabric will change synchronously, thereby ensuring that the relative position and tension degree of the breathable holes on each layer of sub-fabric remain stable.

[0034] In detail, the adjustment assembly comprises a stretching driving module 410, a stretching detection module 420, a first data storage module 430 and a control module 440.

[0035] ​The stretching driving module 410 is configured to drive each of the tension rollers 321 to move in a set direction to change the stretching state of the sub-fabric carried on each of the tension rollers 321. The stretching detection module 420 is configured to detect the stretching force value of each layer of the sub-fabric before sewing and output a detection signal. The first data storage module 430 is configured to store the movement distance of each of the tension rollers 321 and the corresponding stretching force value of the sub-fabric. The control module 440 is in control connection with the stretching driving module 410 and in signal connection with the stretching detection module 420, receives the detection signal and outputs a control signal, and controls the coordinated action of each of the stretching driving modules 410 to maintain the ratio of the stretching force of each layer of the sub-fabric in a set interval.

[0036] As shown in Figure 2 The rack 100 is provided with a plurality of recessed grooves 101, each of which is slidably provided with a mounting sliding block 102, and each of the mounting sliding blocks 102 is protruded at the edge and slidably arranged in the groove 101. A bearing 103 is arranged at the middle position of the mounting sliding block 102, and the axial direction of the bearing 103 is perpendicular to the sliding direction of the mounting sliding block 102 and perpendicular to the rack 100. The aforementioned tension roller set 320 includes a plurality of tension rollers 321, and each of the tension rollers 321 is rotationally connected to the mounting sliding block 102 through the bearing 103. Therefore, when the mounting sliding block 102 moves, the tension roller 321 also moves, and in combination with Figure 1 Therefore, the stretching state (tensioning state) of the sub-fabric carried thereon can be changed.

[0037] In actual application, the stretching driving module 410 can include a hydraulic driving module 411 or a servo driving module according to needs.

[0038] In an embodiment, the stretching driving module 410 is configured as a hydraulic driving module 411. The hydraulic driving module 411 includes a hydraulic pump 4111 in control connection with the control module 440 and a main hydraulic cylinder 4112 in communication with the hydraulic pump 4111. A plurality of sub-hydraulic cylinders 4113 are arranged in communication on the main hydraulic cylinder 4112, and the plurality of sub-hydraulic cylinders 4113 are arranged on the rack 100 and correspond to the mounting sliding blocks 102 one by one. The hydraulic push rod arranged on each of the sub-hydraulic cylinders 4113 is fixedly connected to the mounting sliding block 102, and the extension direction of the hydraulic push rod is parallel to the sliding direction of the mounting sliding block 102. When the hydraulic push rod corresponding to the sub-hydraulic cylinder 4113 moves, the mounting sliding block 102 can be driven to move.

[0039] In the embodiment of the present application, the above-mentioned main hydraulic cylinder 4112 is connected to the multiple sub-hydraulic cylinders 4113 via multiple metal hydraulic pipes 4114. A diverter valve 4115 for controlling the flow of each hydraulic pipe 4114 is provided between the multiple hydraulic pipes 4114 and the main hydraulic cylinder 4112. The diverter valve 4115 is control-connected to the control module 440 and adjusts its own opening and closing parameters in response to the control signal output by the control module 440 to adjust the flow of the oil circuit corresponding to each sub-hydraulic cylinder 4113. At the same time, each sub-hydraulic cylinder 4113 is provided with a hydraulic detection component 4116 for detecting the hydraulic pressure. The above-mentioned hydraulic detection component 4116 includes a pressure sensor, each of which is signal-connected to the control module 440 to detect and output a hydraulic detection signal. The control module 440 receives the hydraulic detection signal corresponding to each sub-hydraulic cylinder 4113 and outputs a control signal to adjust the opening and closing parameters of the diverter valve 4115.

[0040] Based on the above technical solution, multiple sub-hydraulic cylinders 4113 can be controlled simultaneously by changing the hydraulic pressure in the main hydraulic cylinder 4112, and the hydraulic parameters of individual sub-hydraulic cylinders 4113 can also be adjusted as needed. This not only facilitates the coordinated control of the tension rollers 321, controlling the ratio of the tensile forces of each sub-fabric within an appropriate range, ensuring sewing quality and mattress fabric quality, but also allows for flexible adjustment of the parameters of the entire production device when the material of each layer of sub-fabric changes, adapting to the production and processing of different mattress fabrics.

[0041] In another embodiment, the stretching drive module 410 is configured as a servo drive module. The servo drive module primarily comprises a servo drive control module 440 connected to the control module 440 and a plurality of lead screw linear drive modules electrically connected to the servo drive control module 440. In practical applications, the servo drive control module 440 can be configured as an independent control circuit board to convert the control instructions output by the control module 440 into multiple sets of coordinated control signals, or it can be directly loaded as a program module and configured in the main control chip of the control module 440.

[0042] Each linear actuator module includes a mounting base, a servo motor, a ball screw, a guide rail, and a sliding block mounted on the ball screw. The mounting base is bolted to the frame 100. The sliding block is bolted to the corresponding mounting slide 102 of the linear actuator module, transferring its kinetic energy to the mounting slide 102, driving it along the slide 101.

[0043] Based on the above technical solution, the position of each tensioning roller 321 can be adjusted accurately and synchronously, thereby adjusting the tensile force exerted on the sub-fabric carried by each tensioning roller 321, but the ratio of the tensile force exerted on each sub-fabric during the entire adjustment process is always within the set range.

[0044] The tension detection module 420 is mainly used for detecting the tension degree of each sub-fabric.

[0045] In an embodiment, in combination with Figure 3 As shown in the figure, the tension detection module 420 includes an image acquisition module 421, a second data storage module 422, an image recognition module 423, and a tension output module 424.

[0046] The image acquisition module 421 is arranged on the crossbar of the rack 100 and is used for acquiring image data of the fabric to be sewn. In the embodiment of the application, it is specifically configured as a high-definition camera and is used for taking the surface texture image of each layer of sub-fabric. The second data storage module 422 is used for associatively storing various image features of the surface of the sub-fabric and the tension force acting on it, and is specifically stored in the form of a data comparison table. The image features include the texture features of the surface of the sub-fabric, the shape features of the air-permeable holes, etc. For various sub-fabrics, the image of the surface texture after being subjected to a set tension force can be measured and stored in advance.

[0047] The image recognition module 423 is in data connection with the image acquisition module 421 and is internally provided with an identification algorithm for identifying the image features of the surface of the sub-fabric. It receives the image data output by the image acquisition module 421 and identifies and outputs the image features of the surface of the sub-fabric. The tension output module 424 looks up the corresponding tension force from the second data storage module 422 according to the image features and outputs it as the tension detection signal.

[0048] The above technical solution adopts the image recognition mode, can detect and obtain the tension force acting on each sub-fabric in a non-contact manner by analyzing the surface texture image features of the sub-fabric, and is fast, convenient and accurate.

[0049] In another embodiment, the tension detection module 420 includes a pressing wheel, a support rod, and a pressure detection piece.

[0050] The pressing wheel is in contact with the sub-fabric. In order to avoid excessive concentration of stress on the sub-fabric caused by the pressing wheel, the pressing wheel is arranged in a cylindrical shape as a whole to increase the contact area between the pressing wheel and the sub-fabric. When working, the surface of the pressing wheel is in contact with the corresponding sub-fabric. It should be pointed out that the contact here refers to the contact between the pressing wheel and the sub-fabric, and the influence of the pressing wheel itself on the tension state of the sub-fabric can be ignored. In order to make the detection result more accurate, the pressing wheel is arranged close to the laminating roller 331 group 330 in actual application.

[0051] The support rod is arranged between the frame 100 and the pressing wheel and is arranged in two sections. The lower support rod is provided with a sliding groove along its axial direction. One end of the upper support rod is slidably sleeved in the sliding groove and is connected with the lower support rod in an extendable and retractable manner. The bottom of the sliding groove is provided with an elastic member, such as an elastic rubber block or a spring, between the upper support rod and the lower support rod. The end of the upper support rod close to the pressing wheel is provided with a bearing 103 for mounting and supporting the pressing wheel to press the sub-fabric. The pressure detection member is arranged between the upper support rod and the lower support rod, specifically between the elastic member and the bottom of the sliding groove, for detecting the pressure between the upper support rod and the lower support rod and outputting the detection signal.

[0052] The above technical solution uses the pressure between the upper support rod and the lower support rod to know the pressure of the sub-fabric applied to the pressing wheel. Under the premise of knowing the angle between the sub-fabric and the upper support rod, the force can be analyzed and solved to obtain the tension of the sub-fabric under the action of the tension roller 321.

[0053] In actual application, the tension state of the sub-fabric is adjusted by the tension roller 321. Although both the hydraulic drive module 411 and the servo drive module have high movement accuracy, the precision control of the tension state of the sub-fabric is still difficult to reach the ideal level. Therefore, in the embodiment of the present application, the production device further comprises a third data storage module 453. The third data storage module 453 stores a data relationship table between the temperature of each sub-fabric and its tensile strength, i.e., the corresponding tensile force of each type of sub-fabric stretched to a set length under different temperature conditions. In actual production, if the difference between the tension of the sub-fabric and the set threshold is detected and the above difference is lower than a set value, and the adjustment by the stretching drive module 410 cannot compensate for the above difference, the temperature of the sub-fabric can be changed to make the tension state of each layer of sub-fabric of the mattress after sewing in a set range.

[0054] The temperature adjusting member 450 for adjusting the temperature of each sub-fabric and the temperature detection member 451 for detecting the temperature of each sub-fabric are arranged before the laminating roller 331 group 330. The temperature detection member 451 detects the temperature of the sub-fabric to be sewn and outputs a temperature detection signal. The temperature adjusting member 450 is connected with the control module 440. The control module 440 receives and responds to the temperature detection signal and outputs a control signal to adjust the temperature of the sub-fabric to be sewn based on the data relationship table.

[0055] In order to fine-tune the relative position of each sub-fabric in the horizontal direction during sewing, a movable groove is arranged on the slider 102 in the horizontal direction, and a bearing 103 for installing the tension roller 321 is arranged in the movable groove. The outer ring of the bearing 103 is fixedly connected to a movable block arranged in the movable groove. The movable block is in sliding connection with the movable groove, and a plurality of clamping blocks for fixing the relative position of the movable block and the movable groove are arranged between the movable block and the movable groove. The plurality of clamping blocks are in the form of a sheet. In actual application, the position of the movable block can be adjusted and fixed by embedding or removing the clamping blocks on both sides of the movable block.

[0056] In an embodiment, the temperature adjusting member 450 includes a plurality of temperature adjusting roller groups. Each temperature adjusting roller group includes a plurality of temperature adjusting rollers, both ends of each temperature adjusting roller are rotatably arranged on the rack 100 through a bearing 103, and the temperature adjusting rollers are arranged in parallel with the tension rollers 321 and the laminating rollers 331. The temperature adjusting rollers are hollow and have a liquid flow cavity therein. The liquid flow cavity is filled with a heat-conducting fluid, and the liquid flow cavity is in communication with an external temperature adjusting device through a temperature adjusting pipeline. A circulating pump is arranged on the temperature adjusting pipeline. The heat-conducting fluid is configured as water, and the external temperature adjusting device includes a refrigerator and an electric heater for adjusting the temperature of the water flowing therethrough. The temperature detecting member 451 includes an infrared temperature measuring probe arranged on the rack 100 and in signal connection with the control module 440. The detection output end of the infrared temperature measuring probe is in signal connection with the control module 440 for detecting the temperature of the sub-fabric. The circulating pump and the external temperature adjusting device are both in control connection with the control module 440. The control module 440 receives and responds to the temperature signal output by the temperature detecting member 451, and outputs a control signal to control the temperature of the circulating pump and the external temperature adjusting device according to the aforementioned data relationship table, so as to adjust the surface temperature of the temperature adjusting rollers.

[0057] In another embodiment, the temperature adjusting member 450 includes an electric heating radiation plate 452 arranged between the laminating roller group 330 and the tension roller group 320. The electric heating radiation plate 452 has a heat radiation direction towards the side where the sub-fabric is located and is in control connection with the control module 440. The control module 440 controls the heat output of the electric heating radiation plate 452 by controlling the heating power of the electric heating radiation plate 452, so as to adjust the surface temperature of the sub-fabric.

[0058] In the embodiments of the present application, the control module 440 is implemented by using a single-chip microcomputer and its peripheral control circuit. The peripheral control circuit includes a signal sampling conversion and filtering circuit, and the first data storage module 430, the second data storage module 422, and the third data storage module 453 are configured as independent data storage chips in communication connection with the single-chip microcomputer. In a specific embodiment, the data storage chips can also be directly loaded into the storage unit inside the single-chip microcomputer.

[0059] Based on the antibacterial and deodorant fiber polyester knitted mattress fabric production device, an antibacterial and deodorant fiber polyester knitted mattress fabric production method is also disclosed in the embodiments of the present application. Figure 4As shown, mainly includes the following steps: S100, obtain the tensile force value and its ratio of each layer of sub-fabrics of the mattress fabric when the support and ventilation parameters of the mattress fabric reach the maximum under the set extrusion deformation condition and store them.

[0060] S200, based on the antibacterial and deodorant fiber polyester knitted mattress fabric production device as described above, obtain the movement distance of each tension roller 321 and the tensile force value of the corresponding sub-fabric by analysis and calculation or test and store them; S310, detect the tensile force value of each layer of sub-fabrics before sewing and output a tension detection signal; S400, adjust the displacement of each tension roller 321 according to the tension detection signal so that the tensile force value and its ratio of each layer of sub-fabrics are maintained in a set interval; In step S100, the set extrusion deformation condition refers to the pressure applied to the mattress fabric during use, such as the pressure applied to the mattress fabric by an adult of a standard body weight. The support and ventilation parameters are calculated by weighting the ventilation data and support strength data of the mattress fabric. If the ventilation of the mattress fabric is to be highlighted, the weight of the ventilation data can be increased.

[0061] The above production method further comprises: S320, obtain the corresponding relationship between the temperature of each sub-fabric and its tensile strength and store it as a data relationship table; S321, detect the tensile force value of each layer of sub-fabrics before sewing and compare it with a set threshold value: S3211, if the difference between the current tensile force value of the sub-fabric and the set threshold value is less than a set value, then according to the data relationship table, the temperature adjusting member 450 adjusts the temperature of the sub-fabric to a set value; S3212, if the difference between the current tensile force value of the sub-fabric and the set threshold value is greater than a set value, then jump to step S400.

[0062] In the present application, each layer of sub-fabrics to be sewn is placed in a different tensile state just before being sewn together. After sewing, the position of each layer of sub-fabrics of the mattress fabric is relatively fixed. The size of the ventilation holes opened on each sub-fabric will not decrease due to extrusion and stretching when the mattress fabric is used under pressure. Therefore, the ventilation of the mattress fabric during use can be guaranteed. At the same time, for some fabric layers that play a supporting role, they can be pre-stretched to be in a set tensile state, so that the support force of the mattress fabric after sewing is more uniform and stable.

[0063] Although the embodiments of the present application have been shown and described above, it is understood that the above-described embodiments are exemplary and are not to be construed as limiting the present application, and that changes, modifications, substitutions and variations can be made by those skilled in the art without departing from the scope of the present application.
