Description

Technical Field

[0001] The invention belongs to the technical field of cable processing, and in particular relates to a spinning material removing mechanism for a multi-strand twisted cable. Background Art

[0002] In traditional multi-strand twisted cables, in order to ensure the roundness of the cable, the outer circumference of the single-strand or multi-strand core wire is wrapped or filled with a textile material, such as cotton yarn or non-woven fabric. However, when the cable end needs to be wired, the outer sheath is first cut off to expose the core wire, and then the wiring is completed by connecting the core wire to the interface. Therefore, during the wiring process, the textile material (cotton yarn) wrapped around the exposed part needs to be cut off.

[0003] At present, the cutting of spinning material is done manually, and the main tool used is scissors. One hand separates the cotton yarn from the core wire, and the other hand uses scissors to interrupt the cotton yarn. Obviously, this implementation method has the following defects:

[0004] 1) Once the cotton yarn and the core wire cannot be separated from the core wire from the root (the inner end of the core wire that leaks out), the thread ends formed by the cotton yarn after cutting will be long, and the lengths after cutting will be different (the layers will be uneven). Once the wiring is leaked, it will affect the quality and appearance of the wiring;

[0005] 2) The operating efficiency is low, the scissors kiln is easy to blunt, and the work intensity is high. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new spinning material removing mechanism for a multi-strand twisted cable.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A yarn removal mechanism for a multi-strand twisted cable comprises a knife seat, a disc cutter installed in the knife seat, and a driver for driving the disc cutter to rotate around an axis, wherein a cutout which is concave from the outside to the inside and has a relatively smaller diameter is formed on the knife seat, the cutout is relatively penetrated in the axial direction of the disc cutter, and a slope is formed by the outer edge of the end where the cutout is located tilted inward, the blade of the disc cutter is partially exposed from the cutout, the core wire and the yarn enter the cutout relatively separately, the core wire contacts and moves along the slope of the end through the cutout, and the yarn is dragged to move toward the other end through the cutout, and the yarn contacts and cuts the disc cutter from the exposed root.

[0009] Preferably, the incision is located at the front side of the knife seat, and the core wire and the spinning material are relatively separated and enter the incision from front to back. This arrangement is mainly convenient for manual semi-automatic cutting operations.

[0010] According to a specific implementation and preferred aspect of the present invention, the projection of the cut along the axial direction of the disc cutter is symmetrically arranged in the vertical direction with respect to the horizontal extension radial direction of the disc cutter. The advantage of such arrangement is that the disc cutter is convenient for cutting the textile material from the tangent direction, which not only has high cutting quality, but also has little damage to the cutter.

[0011] Preferably, the projection includes a first groove area and a second groove area, wherein the first groove area gradually decreases in diameter from the outside to the inside and is in an isosceles trapezoidal shape, and the second groove area continues to extend inward from the inner end of the first groove area and is in a polygonal shape, and the blade part is located in the second groove area, and when the operator's finger enters the incision by mistake, the first groove area and the corresponding slope separate the finger from the blade part. The setting of the double groove area not only satisfies the cutting function, but also avoids the phenomenon of cutting the finger, and has high safety.

[0012] Furthermore, the second groove area extends inward from the bottom edge of the first groove area and is rectangular, triangular or isosceles trapezoidal. The purpose of such arrangement is to facilitate the cutting of the spinning material by the disc cutter from the tangent direction.

[0013] Preferably, the first groove area and the second groove area form a V-shape with the opening extending inwards, which can be formed in one step, facilitating the processing of the incision.

[0014] According to a specific implementation and preferred aspect of the present invention, the knife seat includes a first seat body and a second seat body connected to each other, wherein an installation cavity is formed between the first seat body and the second seat body, and a knife groove perpendicular to the axial direction of the disc cutter is opened from one radial side edge of the disc cutter in the installation cavity, and the incision is formed by being recessed inward from both sides of the knife groove.

[0015] Preferably, the first seat body and the second seat body are both plate-shaped, the installation cavity is extended or penetrated inwardly by the knife groove along the axis perpendicular to the disc cutter, and the top and bottom are closed. Here, the top and bottom are closed to protect the cutter, and the front-to-back direction is extended to facilitate the molding and processing of the installation cavity.

[0016] Specifically, a notch is formed on one of the first and second bodies, and the notch and the inner wall of the other body form a mounting cavity, wherein the thickness of the body where the notch is located is greater than the thickness of the other body, and the body where the notch is located is arranged close to the driver, and during cutting, the core wire moves along the slope outside the body where the notch is located. The advantages of this design are: 1. It is convenient for forming the mounting cavity (it can be directly disassembled); 2. Since the thickness of the side where the core wire is located is relatively thin, under the guidance of the slope, the core wire has a small deviation, and at this time the root of the spinning material exceeds the corresponding direction deviation (the amplitude is greater than the deflection amplitude of the core wire), so after the disc cutter cuts, it is more conducive to the smoothness of the incision.

[0017] In addition, the driver includes a driving shaft of the vertical disc cutter, a driving motor, and a transmission component that connects the driving motor to the driving shaft, wherein the transmission component includes a driving wheel and a driving belt, and a tensioning adjustment part, the driving wheel is a sprocket or a pulley, the driving belt is a matching chain and belt, and the tensioning adjustment part is used to adjust the tension of the chain or belt.

[0018] The tensioning adjustment part includes an adjustment seat, a tensioning wheel located between two driving wheels and abutting against the outside of the chain or belt, and an adjustment member that pushes the tensioning wheel to move and forces the chain or belt to arch inward for tensioning, wherein the driving shaft is arranged transversely through the adjustment seat, and the two ends are respectively connected to the driving wheel and the disc cutter.

[0019] Specifically, the adjusting member uses conventional bolts to tighten and linear guides to adjust the position of the tensioning wheel relative to the chain or belt.

[0020] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0021] The present invention not only facilitates the guiding tool cutting area for the optimal separation angle between the core wire and the textile material, but also can implement the cutting of the textile material from the exposed root. Therefore, the length of the exposed end of the textile material is relatively neat, thereby ensuring the wiring quality and appearance of the cable wiring end. At the same time, the cutting is convenient, efficient and low in labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 1 and Figure 2 As shown, the yarn removal mechanism for a multi-strand twisted cable of this embodiment includes a knife seat 1, a disc cutter 2 installed in the knife seat 1, and a driver 3 for driving the disc cutter 2 to rotate around its axis, wherein a cut 10 which is concave from the outside to the inside and has a relatively smaller diameter is formed on the knife seat 1, and the cut 10 is relatively penetrated in the axial direction of the disc cutter 2, and a slope m is formed by inward inclination of the outer edge of the end where the cut is penetrated, and the blade portion of the disc cutter 2 is exposed from the cut 10.

[0038] Specifically, the tool holder 1 includes a first seat body 11 and a second seat body 12 connected to each other, wherein a mounting cavity Q is formed between the first seat body 11 and the second seat body 12 .

[0039] The installation cavity Q is provided with a knife groove q1 perpendicular to the axial direction of the disc cutter 2 from one radial side of the disc cutter 2, and the cutouts 10 are formed by being recessed inwards from both sides of the knife groove q1.

[0040] Combination Figures 3 to 5 As shown, the first seat body 11 and the second seat body 12 are both plate-shaped, and the installation cavity Q is penetrated inward by the knife groove q1 along the axial direction perpendicular to the disc cutter 2, and the top and bottom are closed. Here, the top and bottom are closed to protect the cutter, and the front and back directions are penetrated, which is convenient for the molding and processing of the installation cavity.

[0041] Specifically, a notch 120 is formed on the second base body 12 , and the inner wall surface of the first base body 11 is a plane, which closes the notch 120 to form the installation cavity Q.

[0042] In this example, the thickness of the first base body 11 is thinner than that of the second base body 12 , and the driver 3 is mounted on the second base body 12 .

[0043] The incision 10 is located at the front side of the knife holder 1, and the core wire and the spinning material are relatively separated and enter the incision 10 from front to back.

[0044] The cutout 10 is concave from the outside to the inside from the front sides of the first base body 11 and the second base body 12 respectively, and the diameter becomes smaller relatively.

[0045] Meanwhile, the projection formed along the axial direction of the disc cutter 2 is symmetrically arranged up and down about the horizontal extension radial direction of the disc cutter 2. The advantage of such arrangement is that the disc cutter can cut the spinning material in the tangent direction, which not only has high cutting quality but also has little damage to the cutter.

[0046] Specifically, the projection s includes a first groove area s1 and a second groove area s2, wherein the first groove area s1 gradually decreases in diameter from the outside to the inside and is in an isosceles trapezoidal shape, and the second groove area s2 continues to extend inward from the inner end of the first groove area s1 and is in a polygonal shape.

[0047] The blade of the disc cutter 2 is located in the second groove area s2, and when the operator's finger enters the incision 10 by mistake, the first groove area s1 and the corresponding slope m separate the finger from the blade. The double groove area arrangement not only satisfies the cutting function, but also avoids the occurrence of finger cutting, and has high safety.

[0048] The second tank area s2 extends inward from the bottom edge of the first tank area s1 and is rectangular, triangular or isosceles trapezoidal. The purpose of such arrangement is to facilitate the cutting of the spinning material by the disc cutter from the tangent direction.

[0049] In this example, the first groove area s1 and the second groove area s2 form a V-shape with the opening extending inwards, which can be formed in one step, facilitating the processing of the cut.

[0050] Meanwhile, in this example, the slope m on the first seat body 11 or the second seat body 12 is also vertically symmetrical, and therefore, the slope m on the first seat body 11 or the second seat body 12 is also V-shaped.

[0051] The driver 3 includes a driving shaft 30 of the vertical disc cutter 2 , a driving motor 31 , and a transmission component 32 that transmits and connects the driving motor 31 to the driving shaft 30 .

[0052] In this example, the transmission component 32 includes a transmission wheel 320, a transmission belt 321, and a tensioning adjustment part 322, wherein the transmission wheel 320 is respectively fixed on the output shaft of the driving shaft 30 and the driving motor 31, the transmission belt 321 is an annular belt, and the tensioning adjustment part 322 is used for tensioning the annular belt.

[0053] The tensioning adjustment part 322 includes an adjustment seat a, a tensioning wheel b located between the two transmission wheels 320 and in contact with the outside of the annular belt, and an adjustment member c that pushes the tensioning wheel b to move and forces the annular belt to arch inward for tensioning, wherein the drive shaft 30 is arranged to cross the adjustment seat a, and the two ends are respectively connected to the transmission wheel 320 and the disc cutter 2.

[0054] Specifically, the adjusting member c uses conventional bolt tightening and linear guide to adjust the position of the tensioning wheel b relative to the annular belt.

[0055] In this example, the adjusting member c includes a positioning bolt c1 that can be removably installed on the adjusting seat a, a slider c2 having a slide groove c20 for the positioning bolt c1 to pass through, a connecting shaft c3 whose two ends are respectively connected to the slider c2 and the tensioning wheel b, and an adjusting bolt c4 that is arranged on the adjusting seat a and can push the slider c2 to move along the length direction of the slide groove c20.

[0056] Specifically, the adjusting bolt c4 and the slider c2 form a screw nut transmission structure. When the adjusting bolt c4 rotates forward or reverse, the slide groove c20 and the positioning bolt c1 cooperate to implement the slider c2 to be relatively close to or away from the transmission belt 321 along the direction of the slide groove c20, thereby completing the tension adjustment.

[0057] In summary, the implementation process of this embodiment is as follows:

[0058] The spinning material and the core wire are relatively separated and sent into the V-shaped incision 10. The core wire moves along the slope outside the first seat body 11, and the spinning material moves along or away from the slope of the second seat body 12. The core wire and the spinning material that are separated to the extreme are brought into contact with the disc cutter 2 from the exposed root of the spinning material, and the deflected spinning material is cut off from the root in the tangent direction of the disc cutter 2.

[0059] Therefore, this embodiment has the following advantages:

[0060] 1. The cutting area of ​​the guide tool is convenient for the best separation angle between the core wire and the spinning material, and the spinning material can be cut from the exposed root. Therefore, the length of the exposed end of the spinning material is relatively neat, thus ensuring the wiring quality and appearance of the cable wiring end;

[0061] 2. The spinning material keeps deflection and is cut in the tangent direction of the disc cutter. At the same time, because the thickness of the side where the core wire is located is relatively thin, under the guidance of the slope, the core wire is slightly offset. At this time, the root of the spinning material is offset to the left (the amplitude is greater than the deflection amplitude of the core wire). This is more conducive to the smoothness of the incision after the disc cutter cuts. Therefore, not only the cutting efficiency is high and the probability of tool damage is small, but also the end face of the incision is neat, which is conducive to neat and high-quality wiring;

[0062] 3. The design of double groove area and slope not only meets the cutting function, but also avoids cutting fingers, which is highly safe.

[0063] The present invention has been described in detail above, but the present invention is not limited to the above embodiments. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be included in the protection scope of the present invention.
