Description

Technical Field

[0001] This invention relates to the field of data cable manufacturing and processing technology, and in particular to a core feeding device for data cable production. Background Technology

[0002] The cores of a data cable are typically made of copper wire or copper alloy wire, which are braided or twisted together to form a circuit for transmitting data. Different types of data cables can use different numbers and types of cores to provide different performance and transmission speeds.

[0003] The wire cores are stored using a winding method. During the feeding and sheathing process, the wire cores need to be straightened before the sheathing process. Straightening is usually done during feeding. Because individual wire cores are thin and are braided or twisted together, and because the wire cores are wound and stored, there is torque force during feeding. If the torque force is opposite to the direction of the wire core twisting, it will cause the twisted wire cores to loosen. This situation can easily lead to wire breakage. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] To address the issue that during the wire core straightening process, the winding torque is opposite to the wire core interlacing direction, which can cause the interlaced wire cores to become loose and prone to breakage, this invention provides the following technical solution:

[0006] A wire core feeding device for data cable production includes a support assembly, including a fixing plate, and a first assembly connection hole and a second assembly connection hole respectively opened on the fixing plate;

[0007] The guide assembly includes a first guide wheel, which is disposed in a first mounting connection hole of a fixed plate via a telescopic connecting shaft, and the first guide wheel is rotatably sleeved on the telescopic connecting shaft;

[0008] The output component includes a feeding wheel, and there are at least two feeding wheels. The feeding wheels cooperate with each other in pairs. The feeding wheels are mounted on the second assembly connection hole of the fixed plate through a shaft, and the feeding wheels are fixedly connected to the shaft.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] In a preferred embodiment of the wire core feeding device for data cable production according to the present invention, the bottom of the fixing plate is provided with a bottom support plate, the bottom support plate is sleeved on the slide rod, and the two ends of the slide rod are fixedly set on the top of the pad.

[0011] As a preferred embodiment of the wire core feeding device for the data cable production of the present invention, the bottom support plate is provided with a limiting screw, and the pad is provided with a digital scale for distance measurement.

[0012] As a preferred embodiment of the wire core feeding device for data cable production according to the present invention, the telescopic connecting shaft is fitted with a damping spring, one end of which is connected to a fixed plate, and the other end of which is connected to one side of a first guide wheel via a bearing. The inner ring of the first guide wheel is provided with a buffer sleeve, a connecting rod, a main damping groove, a first sleeve, a first damping protrusion, a first damping groove, a second sleeve, and a second damping protrusion. The connecting rod is fitted inside the first sleeve, and the main damping groove on the connecting rod is fitted in conjunction with the first damping protrusion on the inner wall of the first sleeve. The first sleeve is fitted inside the second sleeve, and the first damping groove on the first sleeve is fitted in conjunction with the second damping protrusion on the inner wall of the second sleeve.

[0013] As a preferred embodiment of the wire core feeding device for data cable production according to the present invention, the guiding component further includes a damping sleeve on the inner ring of the second guide wheel, the second guide wheel is disposed in the first assembly connection hole of the fixed plate through a connecting shaft, the second guide wheel is rotatably sleeved on the connecting shaft, and the first guide wheel and the second guide wheel cooperate to guide the wire core.

[0014] As a preferred embodiment of the wire core feeding device for the data cable production of the present invention, a collar is sleeved on the mounting groove of the feeding wheel, and the outer surface of the collar is provided with matching notches at equal intervals, and an extrusion member is provided on the collar.

[0015] As a preferred embodiment of the wire core feeding device for the data cable production of the present invention, the extrusion component includes an extrusion plate and an elastic pad, the extrusion plate is provided with the elastic pad, and the elastic pad is fitted and locked in the matching recess of the collar.

[0016] As a preferred embodiment of the wire core feeding device for the production of the data cable described in this invention, the outer surface of the extrusion plate is provided with anti-slip stripes to prevent slippage when in contact with the wire core surface, and the elastic pad is provided with a groove near the center to allow the extrusion plate to deflect towards the center.

[0017] The beneficial effects of this invention are as follows: at least two feeding rollers clamp the wire core and cooperate with each other. Two identical gears are installed on the mechanism, causing the two feeding rollers to rotate at the same but opposite speeds. Thus, when clamping and feeding the wire core, the wire core is only subjected to the clamping force of the two feeding rollers, and is not subjected to sliding friction resistance, thereby preventing wire core breakage. Furthermore, an elastic pad is provided on the extrusion plate, and the elastic pad has a groove in the middle. When the extrusion plate contacts the surface of the wire core, the wire core is gathered together, making the wire bundle tighter, thereby further preventing the risk of the wire core being torn. Using multiple sets of feeding rollers operating synchronously allows for more stable feeding of the wire core and ensures that the wire core is not torn. In addition, the feeding rollers can also straighten the wire core.

[0018] The beneficial effects of this invention are as follows: a damping spring is installed on the telescopic connecting shaft. One end of the damping spring is fixed to the fixed plate, and the other end is connected to one side of the first guide wheel via a bearing. A buffer sleeve is provided on the inner ring of the first guide wheel. The first guide wheel is used to guide the wound core to the second guide wheel, which in turn guides it to the feeding wheel. Since the core is wound, it may swing when passing through the first guide wheel. The damping spring can slow down the swing of the core, and the buffer sleeve can buffer the vibration of the core. In addition, the damping sleeve on the second guide wheel can prevent tangling caused by the swing or vibration of the core, thereby avoiding the problem of wire breakage due to loose core during subsequent feeding.

[0019] Second, the telescopic connecting shaft is a structure consisting of multiple sleeves and connecting rods. Damping grooves and convex strips are used between each pair of sleeves and connecting rods to prevent rotation during telescopic movement. The multi-sleeve and connecting rod structure also counteracts the reaction force of the buffer sleeve. Furthermore, the identical damping grooves and convex strips between each sleeve ensure consistent frictional resistance. Theoretically, when the first guide wheel oscillates back and forth due to the seam, the more guide wheels there are, the better they counteract the reaction force, resulting in better vibration reduction. This provides more stable output conditions for subsequent seam transmission and also prevents the fixed plate from vibrating due to the seam affecting the first guide wheel.

[0020] The beneficial effects of the present invention are as follows: the bottom of the fixed plate is provided with a bottom support plate, the bottom support plate is sleeved on the slide rod, the two ends of the slide rod are fixedly set on the top of the pad plate, the bottom support plate is provided with a limit screw, and the pad plate is provided with a digital scale for measuring distance. By adjusting the distance between the fixed plate and the winding core, the tension between the first guide wheel and the winding core is controlled, so as to prevent the core from being overstretched and causing the core to break.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example

[0040] Reference Figures 1 to 11 As an embodiment of the present invention, this embodiment provides a core feeding device for data cable production. The support assembly 100 includes a fixed plate 101 and a first assembly connection hole 101a and a second assembly connection hole 101b on the fixed plate 101. The guide component 200 includes a first guide wheel 201 and a telescopic connecting shaft 202. The first guide wheel 201 is fitted into the first assembly connection hole 101a of the fixed plate 101 through the telescopic connecting shaft 202 and rotates. The output assembly 300 includes at least two feeding wheels 301, which are fixedly connected to the second assembly connection hole 101b of the fixed plate 101 through shafts 306.

[0041] The bottom support plate 102 is fixed to the bottom of the plate 101, and the bottom support plate 102 is sleeved on the slide rod 103. The two ends of the slide rod 103 are fixed to the top of the pad plate 105. The bottom support plate 102 is provided with a limit screw 104, and the pad plate 105 is provided with a digital scale 105a, which can be used for distance measurement;

[0042] like Figure 2 , Figure 9 As shown, the bottom of the fixing plate 101 is equipped with a bottom support plate 102, which is fitted onto the slide rod 103. Both ends of the slide rod 103 are fixed to the top of the pad plate 105. The bottom support plate 102 is provided with a limiting screw 104, while the pad plate 105 is provided with a digital scale 105a for distance measurement. By adjusting the distance between the fixing plate 101 and the winding core, the tension between the first guide wheel 201 and the winding core can be controlled to prevent the core from being overstretched and breaking.

[0043] A damping spring 202a is sleeved on the telescopic connecting shaft 202. One end of the damping spring 202a is connected to the fixed plate 101. The other end of the damping spring 202a is connected to one side of the first guide wheel 201 through a bearing. The inner ring of the first guide wheel 201 is provided with a buffer sleeve 201a. The guide assembly 200 also includes a damping sleeve 203a on the inner ring of the second guide wheel 203. The second guide wheel 203 is set in the first assembly connection hole 101a of the fixed plate 101 through the connecting shaft 204. The second guide wheel 203 is rotatably sleeved on the connecting shaft 204. The first guide wheel 201 and the second guide wheel 203 cooperate to guide the wire core.

[0044] like Figure 1 , Figure 3 , Figure 4 As shown, a damping spring 202a is installed on the telescopic connecting shaft 202. One end of the damping spring 202a is fixed to the fixing plate 101, and the other end is connected to one side of the first guide wheel 201 via a bearing. A buffer sleeve 201a is provided on the inner ring of the first guide wheel 201. The first guide wheel 201 is used to guide the wound core to the second guide wheel 203, which in turn guides it to the feeding wheel 301. Since the core is wound, it may swing when passing through the first guide wheel 201. The damping spring 202a can slow down the swing of the core, and the buffer sleeve 201a can buffer the vibration of the core. In addition, the damping sleeve 203a on the second guide wheel 203 can prevent the twisting problem caused by the swinging or vibration of the core, thereby avoiding the problem of wire breakage due to loose core during subsequent feeding.

[0045] like Figures 10-11As shown, the telescopic connecting shaft 202 adopts a structure of multiple sleeves and connecting rods. Damping grooves and ridges are used between the sleeves and between the sleeves and the connecting rods to prevent rotation of the telescopic connecting shaft 202 during telescopic movement. Furthermore, the multi-sleeve and connecting rod structure can counteract the reaction force of the buffer sleeve 201a. The same damping groove and ridge structure is used between each sleeve to ensure uniform frictional resistance. Theoretically, when the first guide wheel 201 oscillates back and forth due to the influence of the stitching, the more sleeves there are, the better the reaction force can be counteracted, thus achieving a better vibration reduction effect. This provides more stable output conditions for subsequent stitching during transmission and also prevents the fixed plate 101 from vibrating due to the influence of the stitching on the first guide wheel 201.

[0046] Furthermore, the telescopic connecting shaft 202 adopts a damping groove and convex strip structure. This damping effect is achieved by setting convex strips and grooves between the sleeve and the connecting rod. The identical shapes of the convex strips and grooves ensure that adjacent sleeves have the same damping characteristics, thus providing a balanced damping force in the swing direction to prevent rotation of the telescopic connecting shaft 202 during telescopic movement. In addition, the multi-section sleeve and connecting rod sleeve structure can counteract the reaction force of the buffer sleeve 201a, allowing the entire system to operate more smoothly. Regarding the stitching effect on the first guide wheel 201, the damping structure of the sleeve and connecting rod can eliminate the reaction force generated during back-and-forth swinging, thereby achieving a vibration reduction effect. Furthermore, the multi-section sleeve and connecting rod sleeve structure can provide more balanced resistance in the swing direction, thereby improving the vibration reduction effect.

[0047] A collar 303 is fitted onto the mounting groove 301a of the feeding roller 301. The outer surface of the collar 303 has equally spaced matching recesses 303a. An extrusion member 302 is provided on the collar 303. The extrusion member 302 includes an extrusion plate 302a and an elastic pad 302b. The elastic pad 302b is provided on the extrusion plate 302a. The elastic pad 302b is fitted into the matching recesses 303a of the collar 303. The outer surface of the extrusion plate 302a is provided with anti-slip stripes 302a-1 to prevent slippage when in contact with the core surface. The elastic pad 302b has a groove 302b-1 near the center to allow the extrusion plate 302a to deflect towards the center.

[0048] It is worth mentioning that the multiple-sleeve configuration provides better cushioning, primarily because it increases the system's damping performance. In the sleeve and connecting rod structure, each sleeve employs the same damping groove and ridge structure, ensuring uniform frictional resistance between adjacent sleeves. When the first guide wheel oscillates back and forth due to the seam, each sleeve generates a reaction force. These reaction forces cancel each other out through the interaction between the sleeves and connecting rods. With the multiple-sleeve structure, these reaction forces can be more evenly distributed among the different sleeves and connecting rods, thus achieving a better damping effect.

[0049] like Figure 1 , Figure 9 , Figures 2-8 As shown, at least two feeding rollers 301 clamp the wire core and cooperate with each other. Two identical gears 305 are mounted on the mechanism, causing the two feeding rollers 301 to rotate at the same but opposite speeds. Thus, when clamping and feeding the wire core, the wire core is only subjected to the clamping force of the two feeding rollers 301, without being subjected to sliding friction resistance, thereby preventing wire core breakage. Furthermore, an elastic pad 302b is provided on the extrusion plate 302a, and the elastic pad 302b has a groove 302b-1 in the middle. When the extrusion plate 302a contacts the surface of the wire core, the wire core is gathered together, making the wire bundle tighter, thereby further preventing the risk of the wire core being torn. Using multiple sets of feeding rollers 301 operating synchronously allows for more stable feeding of the wire core and ensures that the wire core is not torn. In addition, the feeding rollers 301 can also straighten the wire core.

[0050] Working principle: First, the fixed plate 101 is connected to the first guide wheel 201 through the first assembly connection hole 101a, and to the feeding wheel 301 through the second assembly connection hole 101b. The first guide wheel 201 and the second guide wheel 203 in the guide assembly 200 are mounted on the fixed plate 101 through connecting shafts 202 and 204 for guiding the wire core. There are at least two feeding wheels 301, which are mounted on the second assembly connection hole 101b of the fixed plate 101 through shafts 306 and are fixedly connected to the shafts 306. The bottom of the fixed plate 101 is provided with a bottom support plate 102, which is sleeved on the slide rod 103. The two ends of the slide rod 103 are fixedly mounted on the top of the pad 105. The bottom support plate 102 is provided with a limit screw 104 for controlling the height of the wire core. The pad 105 is provided with a digital scale 105a for distance measurement. A damping spring 202a is fitted onto the telescopic connecting shaft 202 to reduce vibration and noise. One end of the spring is connected to one side of the first guide wheel 201 via a bearing. A buffer sleeve 201a is provided on the inner ring of the first guide wheel 201 to reduce friction with the wire core. A damping sleeve 203a is provided on the inner ring of the second guide wheel 203 to control the speed of the wire core. A collar 303 is fitted onto the mounting groove 301a of the feeding wheel 301. The outer surface of the collar 303 has equally spaced fitting recesses 303a. An extrusion member 302 is provided on the collar 303, including an extrusion plate 302a and an elastic pad 302b. The elastic pad 302b is provided on the extrusion plate 302a and fits into the fitting recesses 303a of the collar 303 to fix the wire core. The outer surface of the extrusion plate 302a is provided with anti-slip stripes 302a-1 to prevent slippage when in contact with the wire core surface. The elastic pad 302b has a groove 302b-1 near the center to allow the extrusion plate 302a to deflect towards the center for better fixation of the wire core.
