Description

Technical Field

[0002] PPS diaphragm is a high-performance material based on polyphenylene sulfide fiber. It has the characteristics of high temperature resistance, strong alkali corrosion resistance, high porosity, and excellent electrical insulation. PPS base fabric is the support body and core of the composite diaphragm. It is currently mainly produced by textile production.

[0003] Among them, after the PPS base cloth is produced, in order to prevent the waste edge from affecting the subsequent winding, it is necessary to use a trimming device to cut off the edge of the PPS base cloth;

DETAILED DESCRIPTION

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] Example 1:

[0048] See also Figure 1-10 , a trimming device for textile production, comprising:

[0049] The carrying shaft 1 and the support plate 2 are fixedly connected to the middle part of the bottom end of the support plate 2 with a support base 3, the inner side of the support base 3 is fixedly connected to the support shaft 4, and the outer side of the support shaft 4 is rotatably connected to the support arm A5. The top end of the carrying shaft 1 is provided with a quick-release assembly 6, which is used to cooperate with the carrying shaft 1 to lock the position of the support plate 2;

[0050] Support arm B7, one end of support arm B7 close to support arm A5 is fixedly connected to an assembly shaft 8, and the assembly shaft 8 is also rotatably connected to one end of support arm A5. A positioning assembly 9 is provided on one side of support arm A5, and the positioning assembly 9 is used to cooperate with the support shaft 4 and the assembly shaft 8 to adjust the angle between the support plate 2 and support arm B7;

[0051] The mounting assembly 10 is mounted on the end of the support arm B7 away from the mounting shaft 8. The mounting assembly 10 is equipped with a cold cutting assembly 11 for cutting the selvedge of the PPS base fabric.

[0052] In this embodiment, the quick-install assembly 6 includes:

[0053] Two fixed splints 12, the two fixed splints 12 are fixedly connected to the two ends of the top of the carrying shaft 1, one side of the fixed splint 12 is vertically slidably connected to a stabilizing slide bar 13, and the top of the stabilizing slide bar 13 is fixedly connected to a movable splint 14;

[0054] The transmission seat 15 is fixedly connected to one side of the carrying shaft 1. The transmission seat 15 is rotatably connected to the center shaft 16 inside. Both ends of the center shaft 16 are provided with threaded sections 17, and the threads of the two threaded sections 17 are rotated in opposite directions. The two threaded sections 17 are threadedly connected to the displacement seats 18. The top ends of the two displacement seats 18 are rotatably connected to the displacement push rods 19, and the ends of the two displacement push rods 19 away from the displacement seat 18 are rotatably connected to the two movable splints 14 respectively.

[0055] In this embodiment, the top end of the fixed splint 12 and the bottom end of the movable splint 14 are both provided with an arc groove, and an anti-skid pad is fixedly connected in the arc groove. The anti-skid pad is provided with anti-skid grooves. The arrangement of the arc groove can increase the contact range between the fixed splint 12, the movable splint 14 and the carrying shaft 1, and the arrangement of the anti-skid pad can increase the friction between the fixed splint 12, the movable splint 14 and the carrying shaft 1, thereby preventing the support plate 2 from shaking uncontrollably on the carrying shaft 1.

[0056] In this embodiment, the anti-slip mat is PVC soft rubber, which is made of polyvinyl chloride powder mixed with plasticizers such as dinp / dop, and then added with heat-resistant and color-shifting resistant, and an appropriate amount of toughening agent, anti-aging agent, modifier, etc., and is made through mixing, calendering, vacuum forming and other processes. It has the characteristics of light weight, heat insulation, heat preservation, moisture resistance, flame retardancy, strong bending strength and impact toughness, high elongation when broken, simple construction, etc. It is a mature existing technology and will not be described in detail here;

[0057] In this embodiment, the anti-slip pattern may be:

[0058] Diamond pattern, whose surface is composed of staggered diamond-shaped protrusions, forming multi-directional anti-slip resistance;

[0059] The wave pattern, with its continuous wave-shaped groove design on the surface, can greatly improve the anti-slip resistance;

[0060] Dot / grain texture, with evenly distributed bumps or particles on the surface, can provide dispersed friction contact points;

[0061] The grid pattern, with its regular grid-like grooves and combined with elastic materials, has both anti-slip and cushioning properties;

[0062] Geometric concave-convex patterns, with irregular polygonal or three-dimensional concave-convex structures on the surface, increase friction by increasing the contact area;

[0063] In more detail, the central shaft 16 is rotated, and the connection between the two threaded sections 17 with opposite threads on the central shaft 16 and the displacement seat 18 is coordinated. When the central shaft 16 rotates, the two threaded sections 17 can be used to drive the two displacement seats 18 to move closer to each other. Moreover, since the displacement push rod 19 is connected between the displacement seat 18 and the movable clamping plate 14, when the displacement seat 18 moves, the movable clamping plate 14 can be pulled by the displacement push rod 19, so that the movable clamping plate 14 is supported by the stabilizing slide bar 13 and moves close to the carrying shaft 1 until the movable clamping plate 14 is in close contact with the top end of the carrying shaft 1, and finally the support plate 2 is clamped on the carrying shaft 1 through the fixed clamping plate 12 and the movable clamping plate 14;

[0064] In this embodiment, the positioning component 9 includes:

[0065] Two anti-rotation cylinders 20, the two anti-rotation cylinders 20 are respectively fixedly connected to the two ends of one side of the support arm A5, and the support shaft 4 and the assembly shaft 8 are respectively located on the inner sides of the two anti-rotation cylinders 20. A plurality of anti-rotation rods 21 are slidably connected to the outer sides of the anti-rotation cylinders 20, and each anti-rotation rod 21 is fixedly connected to a anti-rotation plate 22 at one end located on the inner side of the anti-rotation cylinder 20;

[0066] Two linkage rings 23 are rotatably connected to the outside of the two anti-rotation cylinders 20. The linkage rings 23 are provided with arcuate through grooves 24 corresponding to the anti-rotation rods 21. The end of the anti-rotation rod 21 located outside the anti-rotation cylinder 20 is also movably connected to the corresponding arcuate through groove 24. The two linkage rings 23 are fixedly connected to the side close to each other with an extension plate 25. The middle part of the two extension plates 25 is provided with a linkage through groove 26.

[0067] An extension seat 27 is fixedly connected to the middle part of one side of the support arm A5. A transmission screw 28 is vertically rotatably connected to the inner side of the extension seat 27. A displacement push plate 29 is threadedly connected to the transmission screw 28. Both ends of the displacement push plate 29 are fixedly connected to linkage ears 30. One end of the linkage ear 30 is fixedly connected to a linkage column 31. The two linkage columns 31 are movably connected to the inside of the two linkage slots 26 respectively.

[0068] In this embodiment, one end of the anti-rotation rod 21 located outside the anti-rotation cylinder 20 is fixedly connected to an extension rod, and the anti-rotation rod 21 is movably connected to the inside of the arc-shaped through groove 24 through the extension rod, and a rubber sleeve is fixedly connected to the extension rod. Through the setting of the extension rod, when the linkage ring 23 rotates, the extension rod can be pulled or pushed through the arc-shaped through groove 24, thereby driving the anti-rotation rod 21 to perform adaptive displacement, and the setting of the rubber sleeve can protect the extension rod, reduce the loss of the extension rod, thereby improving the service life of the extension rod, and in order to be able to transmit the anti-rotation rod 21 through the arc-shaped through groove 24, the arc-shaped through groove 24 is set obliquely;

[0069] In this embodiment, a linear guide rod is vertically fixedly connected to the inner side of the extension seat 27, and the displacement push plate 29 is also slidably connected to the outer side of the linear guide rod. The arrangement of the linear guide rod can effectively limit the vertical displacement of the displacement push plate 29, preventing the displacement push plate 29 from rotating with the transmission screw 28.

[0070] In more detail, a threaded hole and a limiting hole are provided on the displacement push plate 29, and the transmission screw 28 is connected in the threaded hole, and a clearance fit is formed between the limiting hole and the linear guide rod;

[0071] More specifically, the transmission screw 28 is rotated. Under the connection between the transmission screw 28 and the displacement push plate 29, the displacement push plate 29 can be linearly displaced along the transmission screw 28. In conjunction with the connection between the linkage column 31 and the linkage slot 26, when the displacement push plate 29 linearly displaces, it can press the extension plate 25. Since the extension plate 25 is supported by the linkage ring 23, it can drive the linkage ring 23 to rotate. When the linkage ring 23 rotates, since the anti-rotation rod 21 is also movably connected to the arcuate slot 24 by means of the extension rod, it can drive the anti-rotation plate 22 to slide toward the anti-rotation cylinder 20 through the arcuate slot 24.

[0072] When the anti-rotation plate 22 is separated from the support shaft 4 or the assembly shaft 8, the friction force of the support arm A5 and the support arm B7 can be reduced. Then, the support arm A5 and the support arm B7 can be pulled to adjust the angle between the support arm A5 and the support arm B7 under the support of the support shaft 4 and the assembly shaft 8 until the fixed cutter 44 and the movable cutter 46 are adapted to the transmission position of the PPS base cloth before winding;

[0073] In this embodiment, the mounting assembly 10 includes:

[0074] An assembly ring 32 is fixedly connected to the end of the support arm B7 away from the assembly shaft 8. A notch is formed at the end of the assembly ring 32 away from the support arm B7. Two locking plates 33 are fixedly connected to the notch. A through hole 34 is formed in the middle of each locking plate 33, and a bolt 35 is provided between the two through holes 34.

[0075] In this embodiment, the inner diameter of the locking plate 33 is the same as the diameter of the polished rod 37;

[0076] Example 2:

[0077] See also Figure 1-10 This embodiment provides a technical solution based on the first embodiment: In this embodiment, the cold cutting component 11 includes:

[0078] A carrying bar 36, one end of which is fixedly connected to a polished rod 37, and the carrying bar 36 is assembled on the inner side of the assembly ring 32 through the polished rod 37, and the top end of the carrying bar 36 is laterally slidably connected to a displacement block 39;

[0079] A positioning cylinder 40 is embedded in the middle of one side of the carrying bar 36. A limiting slot 41 is provided on one side of the displacement block 39, and the positioning cylinder 40 is located in the limiting slot 41. One end of the positioning cylinder 40 is threadedly connected to a positioning screw 42.

[0080] A cold cutting seat 43 is fixedly connected to the top of the displacement block 39. A fixed cutter 44 is fixedly connected to the top of the cold cutting seat 43. One end of the top of the cold cutting seat 43 is rotatably connected to a rotating shaft 45. One end of the rotating shaft 45 is fixedly connected to a movable cutter 46. One end of the cold cutting seat 43 is fixedly connected to a transmission motor 47. The output end of the transmission motor 47 is fixedly connected to an eccentric wheel 48. An assembly hole 49 is formed at the end of the movable cutter 46 away from the rotating shaft 45, and the eccentric wheel 48 is also fixedly connected inside the assembly hole 49.

[0081] The eccentric wheel 48 is a wheel-shaped component with an axial hole offset from the center of rotation, a type of cam. As it rotates, the outer edge of the eccentric wheel 48 undergoes periodic displacement due to the eccentricity, thereby driving the movable cutter 46 to oscillate back and forth. This is a mature prior art and will not be further described here.

[0082] In this embodiment, a linear slide 38 is provided at the top of the carrying bar 36, and a linear slider is fixedly connected to the bottom end of the displacement block 39. The displacement block 39 is slidably connected to the inside of the linear slide 38 through the linear slider. The cooperation between the linear slide 38 and the linear slider can effectively guide the displacement of the displacement push plate 29, thereby preventing the displacement push plate 29 from uncontrollable displacement.

[0083] In this embodiment, the cross-sectional shape of the linear slide 38 and the linear slider may be an I-shape. In other embodiments, the linear slide 38 and the linear slider may also be a T-shape or a dovetail shape.

[0084] A support hole is formed at one end of the top of the cold cutting seat 43, and the rotating shaft 45 is connected to the support hole through a ball bearing;

[0085] More specifically, the position where the PPS base fabric needs to be cut is introduced into the gap between the fixed cutter 44 and the movable cutter 46, and the transmission motor 47 is started to drive the eccentric wheel 48 to rotate continuously. Since the eccentric wheel 48 is assembled inside the assembly hole 49, when the eccentric wheel 48 rotates, the movable cutter 46 can follow the rotation of the eccentric wheel 48 and swing back and forth under the support of the rotating shaft 45, thereby cooperating with the fixed cutter 44 to form a cold cutting process of the PPS base fabric and avoid sagging;

[0086] More specifically, the positioning screw 42 is unscrewed from the positioning cylinder 40 to disengage the positioning screw 42 from the displacement block 39, thereby reducing the friction of the displacement block 39 sliding. The displacement block 39 is then pulled to move linearly under the limit of the carrying bar 36, thereby adjusting the operating positions of the fixed cutter 44 and the movable cutter 46 to meet the cutting requirements of different PPS base fabrics.

[0087] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0088] Working principle: first, fix the carrying shaft 1 on the PPS base cloth textile machine near its winding component, then hold the support plate 2, make the fixed splint 12 contact with the bottom end of the carrying shaft 1, and at the same time rotate the central shaft 16, cooperate with the connection between the two threaded sections 17 with opposite threads on the central shaft 16 and the displacement seat 18, when the central shaft 16 rotates, the two displacement seats 18 can be driven to approach each other with the help of the two threaded sections 17, and because the displacement push rod 19 is connected between the displacement seat 18 and the movable splint 14, when the displacement seat 18 moves, the movable splint 14 can be pulled by the displacement push rod 19, prompting the movable splint 14 to approach the carrying shaft 1 under the support of the stabilizing slide bar 13 until the movable splint 14 is in close contact with the top end of the carrying shaft 1, and finally the support plate 2 is clamped on the carrying shaft 1 by the fixed splint 12 and the movable splint 14;

[0089] The transmission screw 28 is rotated. Under the connection between the transmission screw 28 and the displacement push plate 29, the displacement push plate 29 can be linearly displaced along the transmission screw 28. In conjunction with the connection between the linkage column 31 and the linkage slot 26, when the displacement push plate 29 linearly displaces, it can press the extension plate 25. Since the extension plate 25 is supported by the linkage ring 23, it can drive the linkage ring 23 to rotate. When the linkage ring 23 rotates, since the anti-rotation rod 21 is also movably connected to the arcuate slot 24 by means of the extension rod, it can drive the anti-rotation plate 22 to slide toward the anti-rotation cylinder 20 through the arcuate slot 24.

[0090] When the anti-rotation plate 22 is separated from the support shaft 4 or the assembly shaft 8, the friction force of the support arm A5 and the support arm B7 in rotating can be reduced. Subsequently, the support arm A5 and the support arm B7 can be pulled to adjust the angle between the support arm A5 and the support arm B7 under the support of the support shaft 4 and the assembly shaft 8 until the fixed cutter 44 and the movable cutter 46 are adapted to the transmission position of the PPS base cloth before winding. After the support arm A5 and the support arm B7 are adjusted, the transmission screw 28 is rotated to move the anti-rotation plate 22 in the direction close to the support shaft 4 or the assembly shaft 8 until the anti-rotation plate 22 contacts the corresponding support shaft 4 or the assembly shaft 8, thereby increasing the friction force of the support arm A5 and the support arm B7 during rotation, and finally locking the position of the support arm A5 and the support arm B7;

[0091] The position of the PPS base fabric to be cut is introduced into the gap between the fixed cutter 44 and the movable cutter 46, and the transmission motor 47 is started to drive the eccentric wheel 48 to rotate continuously. Since the eccentric wheel 48 is assembled inside the assembly hole 49, when the eccentric wheel 48 rotates, the movable cutter 46 can follow the rotation of the eccentric wheel 48 and swing back and forth under the support of the rotating shaft 45, thereby cooperating with the fixed cutter 44 to form a cold cutting process of the PPS base fabric and avoid the generation of sagging;

[0092] The positioning screw 42 can also be unscrewed from the positioning cylinder 40 to disengage the positioning screw 42 from the displacement block 39, thereby reducing the friction of the displacement block 39 sliding. The displacement block 39 is then pulled to move linearly under the limit of the carrying bar 36, thereby adjusting the operating positions of the fixed cutter 44 and the movable cutter 46 to meet the cutting requirements of different PPS base fabrics.

[0093] The nut of the bolt 35 can be loosened to increase the connection gap between the polished rod 37 and the assembly ring 32, so that the polished rod 37 can rotate inside the assembly ring 32, thereby changing the cutting angles of the fixed cutter 44 and the movable cutter 46;

[0094] In summary, the trimming device used in textile production, through the overall structural coordination, can achieve cold cutting processing of the front edge of the PPS base cloth before winding with the help of the reciprocating swing of the movable cutter 46. Compared with the hot cutting method, it avoids the hanging phenomenon, and the edge is smoother, and the extraction of waste edges is more stable.

[0095] The trimming device for textile production, through the structural coordination of the support arm A5, the support arm B7, the assembly shaft 8 and the positioning component 9, can effectively adjust the operating positions of the fixed cutter 44 and the movable cutter 46 by changing the angle between the support arm A5 and the support arm B7, thereby ensuring the trimming quality of the fixed cutter 44 and the movable cutter 46.
