Description

Technical Field

[0001] The invention relates to the technical field of abdominal pad production equipment, and more particularly to a fabric fixed-length folding processing device. Background Art

[0002] During the operation of the human body, the doctor needs to use an abdominal pad to wipe the blood on the surgical incision and surgical instruments to facilitate the visualization of the relevant parts of the human body and perform the operation accurately. Therefore, the demand for this in hospitals is increasing year by year, and the production efficiency of manufacturers needs to be improved along with the demand. At present, the production process of the abdominal pad is replaced by automated production. The automated production equipment must include a conveying mechanism, a folding mechanism and a sewing mechanism. The conveying mechanism is the most important in realizing automated assembly line production. The conveying of the conveying mechanism determines the finished product effect and sewing efficiency of the subsequent sewing. The present invention relates to the initial feeding mechanism in the conveying mechanism. The current abdominal pad fabric is quantitatively cut and folded during the production process, but the existing quantitative cutting is There are two ways of folding the abdominal pad fabric. One is the traditional manual production, in which the abdominal pad fabric is folded and then quantitatively cut through a size plate. This quantitative cutting is prone to uneven superposition, resulting in skewed cutting edges, and inconsistent cutting sizes of the middle and lower abdominal pad fabrics. The other is automated production, in which the abdominal pad fabric is conveyed to the bottom of the cutting knife through a conveyor roller, and the length of the abdominal pad fabric conveyed is calculated by the number of rotations of the conveyor roller, or the length of the abdominal pad fabric is determined by the positioning point in front of the cutting knife to meet the requirements. The folding mechanism of the abdominal pad fabric is relatively complex and needs to be achieved through the linkage of multiple parts. This quantitative cutting is only suitable for cutting of shorter lengths, and this folding method has low folding efficiency and cannot achieve automated and rapid production.

[0027] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0028] There are two existing quantitative cutting and folding methods. One is traditional manual production, in which the abdominal pad fabric is folded and then quantitatively cut through a size plate. This kind of quantitative cutting is prone to uneven superposition, resulting in skewed cutting edges, and inconsistent cutting sizes of the middle and lower abdominal pad fabrics. The other is automated production, in which the abdominal pad fabric is conveyed to the bottom of the cutting knife through a conveyor roller, and the conveyed length of the abdominal pad fabric is calculated by the number of rotations of the conveyor roller, or the length of the abdominal pad fabric is determined to meet the requirements through the positioning point in front of the cutting knife. The folding mechanism 6 of the abdominal pad fabric is relatively complex and needs to be realized through the linkage of multiple parts. This kind of quantitative cutting is only suitable for cutting of shorter lengths, and this folding method has low folding efficiency and cannot achieve automated and rapid production. Therefore, the present invention designs this fabric fixed-length folding processing device, and the specific structure is as follows Figure 1As shown, the machine comprises a frame 1, the frame 1 comprises a working platform, a discharging roller 2, a feeding roller group 3 and a cutting mechanism 4, the discharging roller 2 is sleeved with an abdominal padding material roll 21, the feeding roller group 3 is used to transport the output fabric of the abdominal padding material roll 21 to the working platform, the feeding roller group 3 comprises an adjusting roller 13, an upper pressing roller 31 and a lower pressing roller 32, connecting plates 33 are respectively provided on both sides of the frame 1, the upper pressing roller 31 and the lower pressing roller 32 are both connected between the connecting plates 33, a rotating motor 34 for driving the lower pressing roller 32 to rotate is provided on the connecting plates 33 on one side, and limiting bolts are provided on the connecting plates 33 on both sides, and one end of the limiting bolts on both sides passes through the corresponding connecting plates 3 The upper surface of the adjusting roller 13 is pressed against the upper pressing roller 31 (the upper pressing roller 31 is adjusted by adjusting the tightness of the limit bolt, so that the spacing between the upper pressing roller 31 and the lower pressing roller 32 can be adjusted, and the conveying speed and tightness of the output fabric can be adjusted). Two vertical slide posts 15 are also provided on both sides of the frame 1. Locking members 16 are provided between the adjusting roller 13 and the two slide posts 15. The adjusting roller 13 is slidably connected to the two slide posts 15 through the locking members 16 (the locking members 16 on both sides are rotated to enable the adjusting roller 13 to move up and down on the slide posts 15, and the output fabric passes through the adjusting roller 13, so the purpose is to adjust the conveying tightness of the conveying surface).

[0029] like Figure 1-8As shown, the cutting mechanism 4 is located on the working platform, and the cutting mechanism 4 is used to cut the output fabric of the abdominal pad fabric roll 21. The frame 1 also includes a folding mechanism and a folding mechanism 6. The folding mechanism includes a folding plate 51 and a first translational power source 52 (motor). The folding plate 51 is located on the upper surface of the working platform. The folding mechanism 6 includes an upper clamping plate 61, a lower clamping plate 62, a pressing plate 63, a second translational power source 64 (cylinder), a third translational power source 65 (cylinder), a first rotational power source 66 (motor) and a second rotational power source 67 (motor). The upper clamping plate 61 and the lower clamping plate 62 are both located below one side of the working platform (this side is the side of the output fabric outlet, that is, the end of the working platform), and the upper clamping plate 61 is located above the lower clamping plate 62, and the pressing plate 63 is located above the lower clamping plate 62. 3 is located above the working platform, and the upper clamping plate 61 and the lower clamping plate 62 are respectively provided with a first slot 611 and a second slot 621. When the conveying fabric is conveyed to the upper part of the upper clamping plate 61, the second translational power source 64 drives the pressing plate 63 to move in the vertical direction, so that the pressing plate 63 presses one side of the output fabric into the first slot 611 (at this time, one side of the output fabric is not aligned with the first slot 611, so the edge will be formed after the pressing plate 63 is inserted into the first slot 611), and the third translational power source 65 drives the upper clamping plate 61 to move in the vertical direction, so that the upper clamping plate 61 lifts one side of the clamped output fabric upward to the upper part of the working platform, and the first rotational power drives the upper clamping plate 61 to rotate in the vertical direction, so that the upper clamping plate 61 presses the clamped output fabric One side of the fabric rotates to be parallel to the working platform, and the first translational force source 52 drives the folding plate 51 to move in the horizontal direction, so that the folding plate 51 pushes the lifted output fabric to one side, and the movement direction of the folding plate 51 is the same as the conveying direction of the output fabric (through the cooperation of the upper clamping plate 61 and the folding plate 51, the upper clamping plate 61 first clamps the head end of the output fabric and lifts it, and then the folding plate 51 moves in the conveying direction of the output fabric so that the folding plate 51 pushes the lifted output fabric to one side of the conveying direction, so that the output fabric can be folded in half. Compared with the existing quantitative cutting mechanism 4, this method can arbitrarily select the required abdominal pad length according to needs, avoiding the problem that the required abdominal pad length is too long and the working platform is not enough to meet the required length). When the material is cut, the second translational power source 64 drives the pressing plate 63 to move in the vertical direction, so that the pressing plate 63 presses the side of the output fabric cut off into the second slot 621, and the second rotational power source 67 drives the lower clamping plate 62 to rotate in the vertical direction, so that the lower clamping plate 62 rotates the clamped side of the output fabric to be parallel to the working platform, and the rotation direction of the upper clamping plate 61 is the same as the rotation direction of the lower clamping plate 62 and both rotate toward the side of the discharge roller 2. Through the cooperation of the upper clamping plate 61, the lower clamping plate 62 and the pressing plate 63, the upper clamping plate 61 first clamps the head end of the output fabric, and the first clamping groove allows the side of the head end of the output fabric to be folded, and the upper clamping plate 61 lifts the output fabric, and then the folding plate 51 is quantitatively folded and cut, and then the output fabric is clamped by the lower clamping plate 62.The second clamping groove allows the side edge of the cut end of the output fabric to be folded, and after the head end is folded, it is aligned and superimposed on the folded edge of the cut end. Compared with the existing folding mechanism 6, this method combines the folds together during the quantitative process, so that the coordination between the various mechanism components is higher, the volume of the equipment is reduced, the work efficiency of quantitative folding, cutting and folding is improved, and the production efficiency of the abdominal pad is greatly improved.

[0030] like Figure 6 As shown, two sets of angle-shifting mechanisms 7 are arranged on one side of the pressing plate 63, and the two sets of angle-shifting mechanisms 7 include an angle-shifting plate 71 and a fourth translational power source 72 (cylinder). Slideways 631 are symmetrically arranged on both sides of the pressing plate 63. The angle-shifting plate 71 includes a connecting portion 711 and an angle-shifting portion 712 protruding downward. The connecting portion 711 is connected to the fourth translational power source 72. An upper limit groove and a lower limit groove are symmetrically arranged on the connecting portion 711 and the angle-shifting portion 712, respectively. The openings of the upper limit groove and the lower limit groove are opposite. The pressing plate 63 at the upper end of the slideway 631 is embedded in the upper limit groove. In the groove, the pressing plate 63 at the lower end of the slide 631 is embedded in the lower limit groove, and the fourth translational force source 72 drives the connecting part 711 to move in the horizontal direction, so that the corner shifting part 712 shifts a corner of the output fabric after folding to the middle of the output fabric, and a corner shifting mechanism 7 is arranged on both sides of the pressing plate 63. The two corners of the folded edge are shifted inward by the corner shifting piece 71 in the corner shifting mechanism 7. The purpose of this process is to prevent the corners from overflowing outward during the process of folding and sewing the fabric, resulting in inadequate sewing of the corners or uneven side sewing, which ultimately leads to a reduction in the production yield.

[0031] like Figure 8 As shown, the cutting mechanism 4 includes a knife frame 41, an upper cutter 42, a lower cutter 43 and a fifth translational power source 44 (cylinder). Vertical slide rails 45 are also provided on both sides of the knife frame 41. The upper cutter 42 is slidably connected between the vertical slide rails 45 on both sides. The lower cutter 43 is located at one side of the working platform. The fifth translational power source 44 drives the upper cutter 42 to move in the vertical direction, so that the upper cutter 42 presses the conveyed fabric downward onto the lower cutter 43 to cut it. The movement direction of the upper cutter 42 is perpendicular to the conveying direction of the output fabric and crosses it (when the upper cutter 42 moves downward to act on the lower cutter 43, the output fabric is cut, and the upper cutter 42 cuts on the width of the output fabric, and the direction of the output fabric when conveyed is the length direction). Figure 7As shown, a clamping mechanism is also provided on the tool holder 41, and the clamping mechanism includes a pressing frame 81, a pressing plate 82, a feeding plate 83, a sixth translational power source 84 (cylinder) and a seventh translational power source 85 (cylinder). The pressing frame 81 is slidably connected between the two sides of the tool holder 41, the feeding plate 83 is located on the tool holder 41, and the feeding plate 83 is on the same plane as the working platform, and the pressing plate 82 is located on the tool holder 41 above the feeding plate 83. The sixth translational power source 84 drives the pressing frame 81 to move in the horizontal direction so that the feeding plate 83 pushes the conveyed fabric to one side of the folding mechanism 6, and the seventh translational power source 85 drives the pressing block to move in the vertical direction so that the pressing block presses on the conveyed fabric on the feeding plate 83. When the upper cutter 42 needs to move downward to act on the lower cutter 43, the purpose is to cut the output fabric, so the pressing plate 82 is required to press the output fabric on one side of the cutter to prevent wrinkles from occurring during the cutting process.

[0032] like Figure 8 As shown, a lifting plate 91 is provided on one side of the lower cutter 43, and an eighth translational power source 92 (cylinder) is provided on both sides of the bottom of the lifting plate 91. The eighth translational power source 92 drives the lifting plate 91 to move in the vertical direction so that the lifting plate 91 lifts the side edge of the cut output fabric. When the upper cutter 42 moves downward and acts on the lower cutter 43, the output fabric is cut off. Then, the cut edge of the output fabric is pressed downward by the upper cutter 42 to one side of the lower cutter 43, that is, below the working platform. Therefore, a parallel lifting plate 91 is provided on one side of the lower cutter 43. When cutting is required, the lifting plate 91 moves downward. When the cutting is completed, the lifting plate 91 is reset upward and one side of the abdominal pad to be cut is lifted upward to be parallel to the working platform for subsequent conveying and folding.

[0033] like Figure 1-2 As shown, a fabric clamping frame 10 is vertically arranged on one side of the working platform, and connecting grooves 11 are respectively arranged at both ends of the upper surface of the fabric clamping frame 10. A pressing mechanism 12 is also arranged on one side of the cutting mechanism 4, and the pressing mechanism 12 includes a fabric clamping strip 121, a ninth translational power source 123 (cylinder) and a tenth translational power source 124 (cylinder). The fabric clamping strip 121 is located above the fabric clamping frame 10, and plugs 122 matching the connecting grooves 11 are respectively arranged on both sides of the bottom of the fabric clamping strip 121. The ninth translational power source 123 is provided with a plug 122 that matches the connecting grooves 11. The fabric clamp 121 is driven to move in the horizontal direction so that the pin 122 of the fabric clamp 121 is aligned with the connecting groove 11, and the tenth translational force source 124 drives the fabric clamp 121 to move in the vertical direction so that the pin 122 of the fabric clamp 121 is inserted into or disengaged from the connecting groove 11. When the output fabric is quantitatively folded and the folded edge cutting is completed, the completed abdominal pad will be transferred to the fabric clamp frame 10, and then pressed on the fabric clamp frame 10 by the fabric clamp 121, and then transported to the sewing mechanism for sewing.

[0034] like Figure 4As shown, an elastic plate 612 is provided in the first slot 611 and the second slot 621, and an elastic cylinder 14 is provided on one side of the elastic plate 612 to drive the elastic plate 612 to move so that the elastic plate 612 can press or detach from the output fabric. When the pressing plate 63 presses the corresponding edges of the output fabric into the first slot 611 and the second slot 621 respectively, the elastic cylinder 14 will drive the elastic plate 612 to press the output fabric pressed into the corresponding slot to prevent it from detaching from the corresponding slot during movement and affecting the subsequent folding.

[0035] Working principle: First, the abdominal pad fabric roll 21 on the discharge roller 2 outputs the fabric and passes through the feed roller group 3 and enters the working platform. When the head edge of the output fabric is transported to the top of the upper clamping plate 61, the pressing plate 63 presses the head edge downward into the first slot 611. At this time, the head edge will form a folded edge. Then the upper clamping plate 61 clamps the head edge of the output fabric and lifts it. Then the folding plate 51 moves in the conveying direction of the output fabric so that the folding plate 51 pushes the lifted output fabric to one side of the conveying direction, so that the output fabric is quantitatively folded in half. After folding in half, the folded edge is reset, and the pressing plate 82 presses the output fabric downward, and the lifting plate 91 moves upward. The upper cutter 42 moves downward and acts on the lower cutter 43 to cut the output fabric. The upper cutter 42 is reset, and the lifting plate 91 moves upward to lift the cut edge upward. The tail edge of the abdominal pad fabric on the front side of the cut is located above the lower clamping plate 62, and the pressing plate 63 presses the head edge into the second slot 621 downward. At this time, the tail edge will form a folded edge. When the head edge and the tail edge are both folded, the upper clamping plate 61 will rotate a certain angle to make the head edge parallel to the working platform, and then the head edge and the tail edge will be released, aligned and stacked, and then transferred to the fabric clamping frame 10, and then pressed by the fabric clamping strip 121 and transported to the sewing equipment for sewing.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
