Description

Technical Field

[0001] The invention relates to the technical field of cloth-pulling machines for processing infant slings, and in particular to an automatic cloth-pulling machine for processing infant slings. Background Art

[0002] Infant slings, also known as baby carriers, baby backpacks, baby sling towels, etc., are wearable products designed specifically for caring for infants and young children. They are mainly used to carry babies on the chest or back of parents. Infant slings use soft and breathable fabrics to provide comfortable support while reducing pressure on the baby's bones and muscles. The production process of infant slings involves multiple key steps, including cutting, sewing, and splicing of fabrics. Each link requires precise fabric control to ensure the comfort, safety and appearance of the final product. Since the original fabric of the sling is in a rolled state, an automatic cloth-pulling machine is needed in the processing of infant slings to unfold the rolled fabric into a multi-layer stacked flat state, and the automatic cloth-pulling machine is used to accurately control the stretching, transmission and positioning of the fabric.

[0003] The invention patent with publication number CN116675040A discloses a cloth pulling machine for convenient cloth loading. When working, the cloth end is clamped and then the cloth is pulled out from the roll and unfolded. Since the pulling device usually clamps the end of the cloth, and the relative lateral movement with the previously laid cloth cannot be completely avoided during the laying process of the cloth, due to the friction between the cloths, the already laid cloth may be affected by the pulling force of the cloth during pulling, resulting in wrinkles or even displacement. Especially when the cloth is long or thick, this phenomenon is easy to occur, resulting in errors in the subsequent sewing and cutting links, thereby affecting the quality of the final product.

[0004] In addition, this patent only clamps the ends of the rolled cloth and then pulls it when laying it out, and the cloth is then naturally unfolded and laid out. Since the inner and outer layers of the rolled cloth are subjected to different compression and bending forces when the rolled cloth is wound, wrinkles are easily formed on the surface of the cloth, and these wrinkles usually appear when the cloth is unfolded. The above method cannot effectively flatten the wrinkles, resulting in the wrinkles still existing when the cloth is pulled out and being laid on the workbench, thereby affecting the subsequent cutting accuracy of the cloth. Summary of the invention

[0005] The present invention provides an automatic cloth-pulling machine for processing baby slings, which solves the technical problems that in the existing cloth-pulling machine, since the cloth-rolling drum is stationary, the end of the cloth roll cannot avoid relative movement with the laid cloth during the pulling process, the friction between the cloths may cause the laid cloth to wrinkle or shift, which is more obvious when the cloth is long or thick, and the compression and bending force of the inner and outer layers of the rolled cloth when it is wound may cause surface wrinkles, and these wrinkles cannot be effectively flattened during the cloth-pulling process, thereby affecting the flatness of the cloth, resulting in insufficient subsequent cutting accuracy, thereby affecting the quality of the final product.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] See also Figure 1 , Figure 4 , Figure 5 and Figure 6The present invention provides a technical solution: an automatic cloth-pulling machine for processing infant slings, comprising a rectangular carrier 1, a cloth-receiving platform 2 located directly below the rectangular carrier 1, a load-bearing telescopic rod group fixedly connected to the four corners of the lower end surface of the rectangular carrier 1, and a support leg 3 fixedly connected to the lower part of the load-bearing telescopic rod group, a guide groove 4 symmetrically arranged in the front and rear of the upper end surface of the rectangular carrier 1, an electric material-moving part 5 for driving the roll of cloth to move is slidably connected in the two guide grooves 4, a cloth-clamping part 6 for clamping the cloth and cooperating with the electric material-moving part 5 to facilitate the spreading of the cloth is arranged on the right part of the upper end surface of the rectangular carrier 1, the electric material-moving part 5 is used to drive the roll of cloth to be spread and moved to prevent the roll of cloth from contacting and rubbing with the laid cloth, resulting in wrinkles on the laid cloth, and the electric material-moving part 5 is composed of two support plates 51 symmetrically distributed in the front and rear and respectively slidably connected in the guide grooves 4, and a connecting frame 52 fixedly connected between the two support plates 51. , a placing fork 53 fixedly connected to the upper part of the support plate 51 for placing the cloth roll, a cloth guide cylinder 54 rotatably connected to the left part between the two support plates 51, a cloth clamping roller group 55 rotatably connected to the right part between the two support plates 51, a pulley power unit 56 arranged on the front side of the front support plate 51 for driving the cloth guide cylinder 54 and the cloth clamping roller group 55 to rotate, and a cutting unit 57 jointly arranged on the right part between the two support plates 51 for cutting the cloth, a smoothing mechanism 7 for smoothing the cloth from the middle to the front and rear sides so as to eliminate cloth wrinkles is arranged in the middle part between the two support plates 51, a tensioning mechanism 8 for tensioning the cloth along the front and rear directions to make the cloth taut during the cloth pulling process is jointly arranged between the two support plates 51, and an intermittent upward movement mechanism 9 for making the rectangular support frame 1 move upward synchronously with the gradually stacked cloth during the cloth pulling process is jointly arranged between the rectangular support frame 1, the support legs 3 and the two support plates 51.

[0037] First, the rolled cloth is placed on the placement fork 53, and then the end of the cloth is pulled through the cloth guide tube 54, the smoothing mechanism 7, the cloth clamping roller group 55 and the tensioning mechanism 8 in sequence, and finally the end of the cloth is placed on the cutting unit 57, and then the electric material moving part 5 is controlled to move rightward as a whole until the electric material moving part 5 moves to the right position of the rectangular carrier frame 1, and then the cloth clamping part 6 is controlled to clamp the end of the cloth, and then the electric material moving part 5 is controlled to move leftward, and the electric material moving part 5 drives the rolled cloth to move and rotate just above the cloth receiving table 2, so that the rolled cloth gradually releases the cloth, and when the electric material moving part 5 moves to the rectangular carrier frame 1, the cloth clamping part 6 is controlled to clamp the end of the cloth, and then the electric material moving part 5 is controlled to move leftward. When the rack 1 moves to the left, the cutting unit 57 is controlled to cut the cloth, and then the electric material moving part 5 can be controlled to move to the right again, and the above steps are repeated. The cloth clamping part 6 clamps the end of the cloth again. During the movement of the electric material moving part 5 to the left, the electric material moving part 5 drives the rolled cloth to rotate and move to release the cloth, so that there is no lateral relative movement between the released cloth and the cloth already laid on the cloth receiving table 2, thereby avoiding the wrinkles or displacement of the already laid cloth caused by the influence of the cloth being pulled out, and ensuring that each layer of the laid cloth can be stably stacked on the cloth receiving table 2.

[0038] See also Figure 1 , Figure 2 and Figure 4 In this embodiment, the intermittent upward movement mechanism 9 includes four rotating shafts 91 which are respectively connected to the corners of the rectangular support frame 1 and correspond to the support legs 3 and are located directly above the corresponding support legs 3. The lower end of the rotating shaft 91 is fixedly connected to a threaded rod 92, and the support leg 3 is fixedly connected to a nut plate 93 which is threadedly connected to the threaded rod 92. The outside of the rotating shaft 91 is commonly connected to a toothed belt pulley assembly 94 for transmission. A top rotation unit 95 for driving the threaded rod 92 to rotate is commonly provided between the two support plates 51 and the two rotating shafts 91 located on the left.

[0039] See also Figure 3 The top rotating unit 95 includes a vertical shaft 951 fixedly connected to the upper end of the rotating shaft 91, a gear plate 952 rotatably connected to the outside of the vertical shaft 951, and a rack 953 fixedly connected to the left end surface of the support plate 51 and meshing with the gear plate 952. A plurality of slots 954 are equidistantly provided on the outer wall of the vertical shaft 951 in the circumferential direction, an annular groove is provided on the upper part of the gear plate 952, and a plurality of lugs are equidistantly fixedly connected to the inner wall of the annular groove. A ratchet 955 cooperating with the slot 954 is hinged on the lug through a torsion spring.

[0040] When the electric material moving part 5 moves to the left part of the rectangular carrier frame 1 and the cutting unit 57 runs to cut the cloth, the electric material moving part 5 is in a stopped state. After the cutting unit 57 completely cuts the cloth, the electric material moving part 5 is controlled again to continue to move to the left for a distance. At this time, the support plate 51 moves to the left to drive the rack 953 to contact and mesh with the gear plate 952, and the rack 953 then drives the gear plate 952 to rotate, and the gear plate 952 then drives the ratchet 955 to rotate, so that the ratchet 955 is stuck in the slot 954, and the ratchet 955 then drives the vertical shaft 951 to rotate synchronously through the slot 954, and the vertical shaft 951 drives the rotating shaft 91 to rotate, and the two rotating shafts 91 on the left side then drive the two rotating shafts 91 on the right side to rotate synchronously through the toothed belt pulley assembly 94, and the rotating shaft 91 Then the threaded rod 92 is driven to rotate. During the rotation of the threaded rod 92, the threaded rod 92 interacts with the nut plate 93 threadedly connected thereto to make the threaded rod 92 move up. The threaded rod 92 then pushes the rectangular carrier 1 to move up. After the rectangular carrier 1 moves up a certain distance, the support plate 51 begins to move to the right. The support plate 51 then drives the rack 953 to move right synchronously. The rack 953 then drives the gear plate 952 to rotate in the opposite direction. The gear plate 952 then drives the ratchet 955 to reverse. After the ratchet switches direction, it disengages from the slot 954, and the gear plate 952 becomes an idling state until the rack 953 moves to the right and separates from the gear plate 952, so that the electric material moving part 5 can move up a certain height each time the cloth is spread out to prevent the cloth spread out later from hitting the cloth spread in front.

[0041] Then the electric material moving part 5 will move to the right again until it moves to the position where the cloth clamping part 6 can clamp the end of the cloth. Then the electric material moving part 5 will move to the left again, and the cloth can be stacked and laid together in sequence. When the cutting unit 57 cuts the cloth and the electric material moving part 5 starts to move left for the second time, the above-mentioned steps of the intermittent upward movement mechanism 9 being triggered and running will be repeated, so that the rectangular carrier frame 1 and the electric material moving part 5 will move up a certain distance synchronously.

[0042] See also Figure 5 , Figure 6 and Figure 7In this embodiment, the smoothing mechanism 7 includes a strip mounting frame 71 fixedly connected to the opposite sides of the two support plates 51, two slide seats 72 symmetrically slidably connected to the strip mounting frame 71 in the front and rear directions, a slide rod 73 running through and slidably connected to the slide seat 72, a strip base 74 fixedly connected to the lower end of the slide rod 73, an elastic strip scraper 75 fixedly connected to the lower end surface of the strip base 74, a support platform 76 fixedly connected between the two support plates 51 and located below the elastic strip scraper 75, a reciprocating drive assembly 77 jointly arranged between the support plate 51 and the strip mounting frame 71 for driving the two slide seats 72 to move back and forth toward each other, and two longitudinal contact and separation assemblies 78 corresponding to the slide rod 73 and symmetrically arranged on the strip mounting frame 71 for driving the slide rod 73 to move longitudinally, thereby controlling the contact and separation of the elastic strip scraper 75 with the cloth.

[0043] See also Figure 7 , Figure 8 and Fig. 9 The longitudinal movement contact assembly 78 includes a strip frame 781 fixedly connected to the upper end surface of the strip mounting frame 71 through a fixed column, a sliding block 782 is slidably connected with an interference fit in the strip frame 781, a C-shaped frame 783 is fixedly connected to the side of the sliding block 782 close to the slide rod 73, a mounting ring 784 is fixedly connected to the left end surface of the C-shaped frame 783, a turntable 785 is rotatably connected in the mounting ring 784, a lever 786 is fixedly connected to the left side of the turntable 785, an end of the lever 786 away from the center of the turntable 785 is hinged to the upper part of the slide rod 73, and a rotation limiting member 784 for limiting the rotation angle of the turntable 785 is provided between the mounting ring 784 and the turntable 785 87, the rotation limiting member 787 includes an arc-shaped guide groove 7871 and a guide column 7872, the mounting ring 784 is provided with an arc-shaped guide groove 7871, the outer wall of the turntable 785 is fixedly connected with a guide column 7872 slidably set in the arc-shaped guide groove 7871, the upper and lower sides of the sliding block 782 are provided with mounting grooves, the groove walls on the opposite sides of the two mounting grooves are fixedly connected with compression springs, and the ends of the two compression springs away from each other are fixedly connected with a top block 11 that fits the inner wall of the bar frame 781, and the compression spring pushes the top block 11 to tightly contact the inner wall of the bar frame 781, so as to indirectly increase the friction resistance of the sliding block 782 when sliding in the bar frame 781.

[0044] See also Figure 5 , Figure 7 and Fig.13The reciprocating drive assembly 77 includes a shaft rod 771 rotatably connected between the two support plates 51, the front end of the shaft rod 771 passes through the front support plate 51 and is fixedly connected to a transmission wheel 772 that is transmission-connected to the pulley power unit 56, the outside of the shaft rod 771 is symmetrically fixedly connected to a reciprocating screw rod cylinder 773 front and back, the left side wall plate of the strip mounting frame 71 is provided with a strip through groove connected to the inside of the strip mounting frame 71, the left end face of the slide seat 72 is fixedly connected to a connecting column 774 slidably set in the strip through groove, and the left end of the connecting column 774 is fixedly connected to a sliding bushing 775 that is threadedly matched with the reciprocating screw rod cylinder 773 and slidably sleeved on the outside of the reciprocating screw rod cylinder 773.

[0045] When the cloth is pulled out, it passes between the elastic strip scraper 75 and the support platform 76. When the pulley power unit 56 is running, it also drives the transmission wheel 772 to rotate, and the transmission wheel 772 then drives the shaft 771 to rotate, and the shaft 771 further drives the reciprocating screw rod cylinder 773 to rotate, and the reciprocating screw rod cylinder 773 drives the sliding bushing 775 matched with its thread to move back and forth. The movement directions of the two sliding bushings 775 are opposite. The sliding bushing 775 drives the sliding seat 72 to move back and forth synchronously through the connecting column 774. When the two sliding seats 72 are removed from the strip mounting frame 71, When the middle parts move in the direction away from each other, the slide seat 72 will drive the slide bar 73 to move synchronously, and the slide bar 73 will drive the turntable 785 to rotate through the lever 786, and the turntable 785 will drive the guide column 7872 to slide in the arc-shaped guide groove 7871 until the guide column 7872 slides and hits the groove wall of the arc-shaped guide groove 7871 at the lower part. In the process of the guide column 7872 sliding downward in the arc-shaped guide groove 7871, the slide bar 73 also continues to move downward until it drives the elastic strip scraper 75 to move downward and hit the surface of the cloth on the support platform 76.

[0046] Then the slide bar 73 drives the mounting ring 784 to move horizontally through the lever 786 and the turntable 785, and the mounting ring 784 then drives the sliding block 782 to move through the C-shaped frame 783 (at this time, the force driven on the sliding block 782 is greater than the friction between the sliding block 782 and the strip frame 781). During the movement of the two elastic strip scrapers 75 away from each other, the cloth is pulled from the middle to the front and rear sides to flatten the wrinkles on the cloth.

[0047] When the two slides 72 move to the farthest distance, the reciprocating screw rod tube 773 will drive the two slides 72 to move closer to each other, and the slide 72 will then drive the slide bar 73 to move closer to the middle of the strip mounting frame 71, and the slide bar 73 will drive the turntable 785 to rotate in the opposite direction through the lever 786, and the turntable 785 will drive the guide column 7872 to rotate upward in the arc-shaped guide groove 7871. During this process, the lever 786 will drive the slide bar 73 to gradually move upward until the guide column 7872 rotates to the highest position, that is, it contacts the arc-shaped guide groove 7871. 871 upper groove wall, at this time, the slide bar 73 has also moved up completely, and the elastic strip scraper 75 has also moved up to separate from the cloth on the support platform 76; then the slide bar 73 drives the mounting ring 784 to move horizontally through the lever 786 and the turntable 785, and the mounting ring 784 then drives the slide block 782 to move in the strip frame 781 through the C-shaped frame 783, until the slide bar 73 drives the elastic strip scraper 75 to move to the middle position of the strip mounting frame 71. During this process, the elastic strip scraper 75 is in a separated state from the cloth on the support platform 76.

[0048] When the two elastic strip scrapers 75 are driven by the slide rod 73 to move to the shortest distance, the slide seat 72 will again change to a state of moving away from each other. During the process of the two slide seats 72 moving away from each other, the elastic strip scrapers 75 will again move down and come into contact with the surface of the cloth, so as to automatically eliminate the wrinkles on the surface of the cloth.

[0049] See also Figure 5 , Figure 6 , Fig.10 , Fig.11 , Fig.12 and Fig.14 In this embodiment, the tensioning mechanism 8 includes a roller 81 rotatably connected between the two support plates 51 and transmission-connected to the pulley power unit 56, and two rectangular frames 82 symmetrically distributed front and back and fixedly connected to the opposite sides of the support plates 51 and located directly above the roller 81. An L-shaped plate 83 is slidably connected in the rectangular frame 82. A top spring 84 is fixedly connected between the transverse section of the L-shaped plate 83 and the rectangular frame 82. An arc plate 85 is fixedly connected to the lower side of the vertical section of the L-shaped plate 83. The lower surface of the arc plate 85 is fixedly connected along its own curvature at equal distances. A plurality of pillars 86 are connected, and two rows of pillars 86 are arranged in a staggered distribution in the front and rear. A strip frame 87 is slidably connected to the outside of the pillar 86. Two limit pillars 88 are symmetrically embedded and fixedly connected to the pillar 86 and respectively abut against the upper and lower opposite sides of the strip frame 87. A limit spring is fixedly connected between the pillar 86 and the strip frame 87. A flexible roller 89 is rotatably connected between the front and rear corresponding strip frames 87. Arc grooves are provided on the left and right parts of the arc plate 85, and a corner column 10 is rotatably connected in the arc groove through a pivot.

[0050] After the cloth passes through the cloth clamping roller group 55, it will pass through the roller 81 and the curved plate 85. When the cloth passes between the roller 81 and the curved plate 85, the corner column 10 is used to protect the cloth to prevent the cloth from contacting the corner of the curved plate 85 and causing damage. Under the push of the top spring 84, the L-shaped plate 83 moves downward, the L-shaped plate 83 drives the curved plate 85 to move downward, and the curved plate 85 drives the flexible roller 89 to move downward. The flexible roller 89 moves downward to clamp the cloth tightly between it and the roller 81. At the same time, the flexible roller 89 will also be deformed and bent under the push of the top spring 84, and then move along As the outer part of the roller 81 is bent, the flexible roller 89 will drive the front and rear symmetrical strip frames 781 to move closer to each other during the bending process, and the strip frames 781 will drive the limit springs to deform. When the cloth is pulled out, the pulley power unit 56 will also drive the roller 81 to rotate. As the cloth is continuously pulled out, the flexible roller 89 will also be driven to rotate. The obliquely arranged flexible rods will apply a pulling force from the middle to both sides of the cloth during its rotation, so that the cloth is in a taut state, thereby further eliminating wrinkles and ensuring that the cloth pulled out and laid on the cloth receiving table 2 remains flat.

[0051] During operation, the electric material moving part 5 is controlled to move to the right position of the rectangular carrier frame 1, the rolled cloth is placed in the electric material moving part 5, and then the cloth is pulled through the electric material moving part 5, the cloth clamping part 6 is controlled to clamp the cloth, and then the electric material moving part 5 is controlled to move to the left to flatten the rolled cloth and spread it on the cloth receiving table 2. At the same time, the smoothing mechanism 7 and the tensioning mechanism 8 will also be synchronously triggered to run, and the cloth is pulled from the middle to the front and rear sides to eliminate the wrinkles of the cloth and keep the cloth In the tensioned state, after the electric material moving part 5 has flattened the cloth, the cloth is cut, and then the electric material moving part 5 moves to the left for a distance again, and then triggers the intermittent upward movement mechanism 9 to operate, so that the rectangular carrier 1 rises a certain height, and then the electric material moving part 5 moves to the right again, until it moves to the rightmost position of the rectangular carrier 1, and then repeats the above-mentioned steps of clamping the cloth with the cloth clamping part 6 and moving the electric material moving part 5 to the left, and the next layer of cloth can be flattened.
