Cable threading machine

Abstract

A cable threading machine. By configuring the groove width of an accommodating groove to be equal to the width of a traction member, the traction member for pulling a cable can be wound in the accommodating groove only in a single-row stacked manner, such that the unfavorable problem of the traction member being intertwined or overlapped in a staggered manner on a cable reel is avoided, thereby preventing accidental deformation of the traction member; and by the provision of a sliding member and a sliding guide structure, the end of the traction member located in the accommodating groove gradually moves towards the periphery of the cable reel during unwinding, such that the traction member can be positioned as close as possible to or in contact with the periphery of the cable reel. In this way, the traction member can be fed in the direction that is as tangential as possible to the periphery of the cable reel, and the lateral sides of the traction member are effectively supported, thereby preventing the problem of the traction member being bent due to excessive resistance during unwinding.

Description

Stringing Machine Technical Field

[0001] The present invention relates to the field of cable guiding, in particular to a cable stringing machine. Background Art

[0002] Stringing machines have become essential equipment for modern construction, significantly improving the accuracy and consistency of cable installation and significantly increasing construction efficiency. Typically, a stringing machine uses an electric, pneumatic, or hydraulic drive to rotate a sliding disc. A traction member, used to pull the cable, is wound around the disc, with one end secured to the disc. Controlling the direction of rotation of the disc drives the traction member to retract and unreel, allowing the traction member to move the cable for installation.

[0003] However, the threading machines in the related art generally have certain shortcomings in actual use. The winding of the traction parts is too chaotic, resulting in various positioning problems such as the traction parts being easily overlapped on the slide plate and the traction parts with different numbers of turns being entangled with each other. This further causes the traction parts to be easily bent, kinked or bound during the subsequent unwinding process.

[0004] Secondly, even if there is no overlapping problem with the traction parts, if there is little room for unwinding of the traction parts on the slide, if the unwinding resistance is large and the strength of the traction parts themselves is limited, the traction parts are also prone to bending and deformation.

Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0067] FIG1 and FIG2 show a wire stringing machine 10 in some embodiments of the present invention. The wire stringing machine 10 is used to pull a cable to move along a predetermined trajectory, thereby completing the installation of the cable.

[0068] As shown in FIG. 1 to FIG. 5 , the stringing machine 10 includes a housing 1 , a winding device 2 disposed in the housing 1 , and a sliding device 3 disposed on the winding device 2 .

[0069] It can be understood that the housing 1 accommodates the winding device 2 and the sliding device 3. The winding device 2 pulls the cable to move, while the sliding device 3 prevents bending.

[0070] As shown in FIG3 to FIG5 , the winding device 2 includes a wire drum 21 and a traction member 22 . The wire drum 21 is rotatably disposed on the housing 1 . A guide track 33 is provided on the wire drum 21 . The traction member 22 is wound on the wire drum 21 .

[0071] As will be understood, the wire drum 21 is used to drive the traction member 22 to reel or unreel during rotation, with the specific reeling or unreeling direction determined by the rotation direction of the wire drum 21. The rotation of the wire drum 21 can be configured to be driven by an electric drive, a hydraulic drive, or a pneumatic drive as known in the art. The wire drum 21 also accommodates the traction member 22.

[0072] As shown in Figures 3 to 7, the sliding device 3 is slidably set on the guide track 33, and the end of the traction member 22 is fixed on the sliding device 3. When the wire drum 21 rotates to reel the traction member 22, the sliding device 3 moves toward the center of the wire drum 21; when the wire drum 21 rotates to unwind the traction member 22, the sliding device 3 moves toward the center of the wire drum 21.

[0073] It can be understood that when the wire drum 21 rotates to unwind the traction member 22, that is, when the traction member 22 is drawn out from the wire drum 21 and passes through the shell 1, the sliding member 32 will drive the end of the traction member 22 to move along the guide track 33 in the direction away from the center of the wire drum 21.

[0074] When the wire drum 21 rotates to reel the traction member 22 , that is, when the traction member 22 is received into the housing 1 and recovered on the wire drum 21 , the sliding member 32 will drive the end of the traction member 22 to move along the guide track 33 toward the center of the wire drum 21 .

[0075] It should be noted that the guide track 33 serves to define the sliding track of the sliding device 3. The length, profile, and location of the guide track 33 can be flexibly set. Of course, when selecting specific parameters, simulation software in the prior art can be used to determine more optimal parameters while keeping other influencing parameters fixed, and then apply them.

[0076] When the sliding member 32 moves toward the center of the wire drum 21, the end of the traction member 22 will gradually move toward the center of the wire drum 21, so that the traction member 22 can be gradually reeled. It should be noted here that during the reeling process, the traction member 22 located on the outer ring of the wire drum 21 will gradually form a force to retract toward the center of the wire drum 21. You can refer to the process of reeling a piece of paper. As the traction member 22 of the outer ring gradually retracts, the traction member of the inner ring will also be affected by the retraction force and gradually move toward the center of the wire drum 21 in a spiral inward manner.

[0077] When the sliding member 32 moves away from the center of the wire drum 21, the end of the traction member 22 located on the wire drum 21 will gradually move toward the periphery of the wire drum 21, so that the inner circle of the traction member 22 in the wound state will continue to expand during the unwinding process, that is, the inner circle of the traction member 22 in the wound state will gradually approach the periphery of the wire drum 21. In this way, the winding portion of the traction member 22 currently being unwound can fully fit the periphery of the wire drum 21, which also allows the traction member 22 to be fully supported by the periphery of the wire drum 21, thereby preventing the traction member 22 from bending.

[0078] It should be noted that in order to enable the outer periphery of the wire drum 21 to support the current number of unwinding turns of the traction member 22, a limiting structure or a guiding structure matching the outer periphery profile of the wire drum 21 can be provided on the shell 1.

[0079] It should also be noted that during actual construction, the traction member 22 will experience a certain load when winding or unwinding due to friction with the outside world, etc. When winding under load, the traction member 22 may initially become stuck due to the load. However, as the wire drum 21 continues to rotate, the sliding member 32 gradually approaches the center of the wire drum 21 and becomes fixed. Subsequently, with further rotation of the wire drum 21, the traction member 22 is able to overcome the load and rewind.

[0080] When unwinding is performed under load, if the traction member 22 is stuck in unwinding, as the wire drum 21 continues to rotate, the sliding member 32 will move to a position on the guide track 33 away from the center of the wire drum 21 under the force transmitted from the traction member 22. The greater the unwinding load, the greater the force transmitted from the traction member 22 to the sliding member 32, the greater the expansion of the inner circle of the traction member 22, and the closer the current unwinding number of turns is to the outer periphery of the wire drum 21. In this fully fitted state, the two sides of the current unwinding number of turns can be respectively limited and supported by the inner circle part of the traction member 22 and the outer periphery of the wire drum 21, thereby fully preventing the traction member 22 from accidentally bending, that is, the current unwinding number of turns on the traction member 2 will always be supported from both the inside and outside.

[0081] As shown in Figures 3 to 6, a receiving groove 211 is opened on the wire drum 21, and the traction member 22 is wound and arranged in the receiving groove 211. The width W1 of the receiving groove 211 corresponds to the width W2 of the traction member 22, so that the traction member 22 overlaps in a single row in the receiving groove 211.

[0082] It can be understood that the accommodating groove 211 is used to accommodate the traction member 22; the width W1 of the accommodating groove 211 corresponds to the width W2 of the traction member 22, which means that the width W1 of the accommodating groove 211 is configured to accommodate only a single row of traction members 22, that is, the parts of the traction member 22 with different winding layers after winding cannot be arranged side by side or overlap in the accommodating groove 211. It is preferred to configure the width W1 of the accommodating groove 211 to be equal to or slightly larger than the width W2 of the traction member 22.

[0083] It should be noted that the single-row overlapping traction member 22 means that the different winding layers on the traction member 22 in the wound state are only stacked up and down, that is, the winding layers of the traction member 22 after winding are gradually spirally wound on the same end face.

[0084] As shown in FIG. 3 to FIG. 7 , the guide track 33 has a proximal end 331 close to the bottom of the accommodating groove 211 and a distal end 332 close to the notch of the accommodating groove 211 (see FIG. 4 for the proximal end 331 and the distal end 332 ).

[0085] During specific application, when the wire drum 21 rotates to unwind the traction member 22, the sliding member 32 drives the end of the traction member 22 to move along the guide track 33 toward the direction close to the distal end 332; when the wire drum 21 rotates to reel in the traction member 22, the sliding member 32 drives the end of the traction member 22 to move along the guide track 33 toward the direction close to the proximal end 331.

[0086] It can be understood that the proximal end 331 is closer to the center of the wire drum 21 than the distal end 332 , and the distal end 332 is closer to the periphery of the wire drum 21 than the proximal end 331 .

[0087] As shown in Figure 3, in some embodiments of the stringing machine 10, a limiting peripheral wall 11 is provided in the shell 1, and the limiting peripheral wall 11 is arranged around the outer side of the periphery of the wire reel 21. Each limiting peripheral wall 11 jointly covers the notch of the accommodating groove 211, thereby confining the traction member 22 in the accommodating groove 211.

[0088] It is understood that the limiting peripheral wall 11 can be configured as a continuous convex wall or as a plurality of spaced convex walls. The limiting peripheral wall 11 can define a chamber within the housing 1 for accommodating the wire drum 21. The limiting peripheral walls 11 collectively position the wire drum 21 so that the wire drum 21 can only rotate within the chamber. On the other hand, the limiting peripheral wall 11 has a certain shielding effect on the accommodating groove 211. Under the shielding of the limiting peripheral wall 11, the traction member 22 can be effectively confined within the accommodating groove 211, preventing the traction member 22 from being dislodged and stuck.

[0089] It should be noted that, in actual use, even if the limiting peripheral wall 11 is not provided inside the shell 1 , it will not affect the normal use of the product.

[0090] As shown in Figures 3 to 7, the sliding device 3 includes a sliding guide structure 31 and a sliding member 32; the sliding guide structure 31 is arranged on the wire drum 21, and the sliding guide structure 31 defines a guide track 33 on the wire drum 21. The sliding member 32 is slidably arranged on the guide track 33, and the end of the traction member 22 is arranged on the sliding member 32; when the wire drum rotates, the sliding member 32 drives the end of the traction member 22 to move along the guide track 33.

[0091] It can be understood that the sliding guide structure 31 serves to define the sliding track of the sliding member 32. The sliding member 32 serves to fix one end of the traction member 22, and the other end of the traction member 22 is used to pull the cable to move to complete the cable setting.

[0092] It should be noted that the sliding guide structure 31 can be defined by a groove, a hole or other recessed structure, or can be defined by a shaft, a guide rail or other structure with a protrusion.

[0093] As shown in FIG4 and FIG8, in some embodiments of the stringing machine 10, the guide track 33 is a straight line or a curve, or the traction member 22 is a metal belt; or the width of the traction member is 3 mm to 7.8 mm, and the thickness T2 of the traction member 22 is 0.5 mm to 1.2 mm.

[0094] It can be understood that when the guide track 33 is straight, the slider 32 can move along the straight line toward or away from the center of the wire drum. When the guide track 33 is curved, the slider 32 moves along the curve toward or away from the center of the wire drum. Configuring the traction member as a metal belt can increase its strength and durability. Setting the traction member width to 3 mm to 7.8 mm and the traction member thickness T2 to 0.5 mm to 1.2 mm can make the traction member 22 flatter overall.

[0095] It should be noted that no matter whether the guide track 33 is set to a straight line or a curve, it is necessary to ensure that the sliding member 32 moves toward the center of the wire drum when the traction member 22 is wound, and moves away from the center of the wire drum when the traction member 22 is unwound.

[0096] In some embodiments, the guide track 33 is further provided with a proximal end 331 and a distal end 332, and the bobbin is provided with a receiving groove 211. The proximal end 331 is close to or located at the bottom of the receiving groove 211, while the distal end 332 is close to or located at the notch of the receiving groove 211. In this way, the outline of the guide track 33 can be defined on the bobbin 21.

[0097] As shown in Figures 8 and 9, in some embodiments of the stringing machine 10, the sliding member 32 includes a seat body 321 and a fixing structure 323. The seat body 321 is located on the wire reel 21. The seat body 321 can slide along the guide track 33. The fixing structure 323 is used to fix the end of the traction member 22 on the seat body 321.

[0098] It can be understood that the seat 321 is used to drive the end of the pulling member 22 in the wire drum 21 to move together, and the fixing structure 323 is used to fix the end of the pulling member 22 in the wire drum 21 to the seat 321. The seat 321 is limited to slide along the guide track 33 to prevent deviation.

[0099] It should be noted that the fixing structure 323 can be configured to fix the end of the traction member 22 by plugging, clamping, screwing, locking and other methods in the relevant technology.

[0100] As shown in Figure 7, in some embodiments of the stringing machine 10, the sliding guide structure 31 includes a first sliding track 311 and a second sliding track 312, and the first sliding track 311 and the second sliding track 312 are respectively located on two opposite sides of the wire reel 21, and the first sliding track 311 and the second sliding track 312 are aligned; the seat body 321 is located between the first sliding track 311 and the second sliding track 312, and the seat body 321 is slidably set on the first sliding track 311 and the second sliding track 312, respectively.

[0101] It is understandable that the seat 321 is always defined between the first sliding track 311 and the second sliding track 312. In this way, the end of the traction member 22 can be always confined within the position on the spool 21 for accommodating the traction member 22. The first sliding track 311 and the second sliding track 312 can be defined by the same structure, such as a groove, hole, track, or guide rail, or they can be defined by different structures. For example, the first sliding track 311 is defined by one of the various structures such as a groove, hole, track, or guide rail, while the second sliding track 312 is defined by another of the various structures such as a groove, hole, track, or guide rail.

[0102] In order to enable the sliding guide structure 31 to smoothly define the first sliding track 311 and the second sliding track 312 to guide the sliding track of the seat 321, the sliding guide structure 31 has at least the following embodiments:

[0103] In the first embodiment, the sliding guide structure 31 includes a first sliding groove and a second sliding groove. The first sliding groove defines a first sliding track 311 on the wire drum 21, and the second sliding groove defines a second sliding track 312 on the wire drum 21. The seat body 321 is slidably connected in the first sliding groove and the second sliding groove respectively.

[0104] It is understandable that in this embodiment, two different positions of the seat body 321 are guided and limited by two grooves. By further determining the range of motion of the two points while maintaining the overall size of the seat body 321, the sliding trajectory of the entire seat body 321 can be determined, thereby further establishing the range of motion of the end of the pulling member 22. The sliding connection between the seat body 321 and the first and second chute grooves can be a direct contact surface-to-surface sliding friction, or a rolling friction connection using other structures that facilitate sliding.

[0105] In a second embodiment, as shown in FIG7 , the sliding guide structure 31 includes a first sliding hole 3111 and a second sliding hole 3121 . The first sliding hole 3111 defines a first sliding track 311 on the wire drum 21 , and the second sliding hole 3121 defines a second sliding track 312 on the wire drum 21 . The base 321 is slidably connected to the first sliding hole 3111 and the second sliding hole 3121 , respectively.

[0106] It is understandable that in this embodiment, two holes are used to guide and limit the two different positions of the seat body 321, thereby also limiting the sliding trajectory of the seat body 321. The first sliding hole 3111 and the second sliding hole 3121 are both configured as elongated waist holes, and the hole wall profiles of the first sliding hole 3111 and the second sliding hole 3121 are preferably configured to be identical. The first sliding hole 3111 and the second sliding hole 3121 can both be configured as a straight structure or have a certain degree of curvature. The sliding connection between the seat body 321 and the first sliding hole 3111 and the second sliding hole 3121 can be direct contact surface-to-surface sliding friction, or rolling friction through other structures that facilitate sliding.

[0107] As shown in FIG8 and FIG9 , the sliding member 32 further includes a plurality of sliding wheels 322 ; each sliding wheel 322 is rotatably disposed on the base 321 , some sliding wheels 322 are slidably disposed on the first sliding track 311 , and the remaining sliding wheels 322 are slidably disposed on the second sliding track 312 .

[0108] It can be understood that the sliding wheel 322 is used to support the sliding of the seat body 321. The sliding wheel 322 is limited to the sliding guide structure 31, thereby ensuring that the seat body 321 can slide along the guide track 33 to prevent deviation.

[0109] Specifically, in some embodiments, the number of the sliding wheels 322 can be configured to be two, wherein one sliding wheel 322 is slidably disposed on the first sliding track 311 , and the other sliding wheel 322 is slidably disposed on the second sliding track 312 .

[0110] Specifically, the sliding member 32 includes four sliding wheels, two of which are slidably disposed within the first sliding track 311, and the remaining sliding wheels are slidably disposed within the second sliding track 312. Steps can be provided on both the first sliding track 311 and the second sliding track 312, and the sliding wheels 322 disposed within the first sliding track 311 and the second sliding track 312 will abut against the steps, thereby limiting the position of each sliding wheel 322 and preventing it from falling out.

[0111] In some embodiments, the sliding wheel 322 may be configured in a columnar shape, and the columnar structure is rotatably disposed on the base 321. It can be understood that the base 321 can slide along a predetermined track through the columnar structure.

[0112] In some embodiments, the sliding wheel 322 may be configured in a spherical shape, and the spherical structure is rotatably disposed on the base 321. It can be understood that the base 321 can slide along a predetermined track through the spherical structure.

[0113] In other embodiments of the stringing machine 10, the sliding guide structure 31 may be configured to include only the first sliding track 311. Specifically, the sliding member 32 may be guided solely by the first sliding track 311. It is understood that even if the sliding member 32 is guided solely by the first sliding track 311, the retraction and unretraction of the traction member 22 can still be successfully completed.

[0114] In other embodiments of the stringing machine 10, the sliding guide structure 31 may also be configured to include only the second sliding track 312. Specifically, the sliding member 32 may be guided solely by the second sliding track 312. It is understood that even if the sliding member 32 is guided solely by the second sliding track 312, the retraction and unretraction of the traction member 22 can still be successfully completed.

[0115] In order to enable the fixing structure 323 to fix the end of the pulling member 22 on the base 321, the fixing structure 323 has at least the following embodiments:

[0116] The first type, as shown in Figures 8 and 9, the fixing structure 323 includes a fixing groove 3231a and a locking pin 3232a. The fixing groove 3231a is opened on the seat body 321, and the locking pin 3232a is passed through the end of the traction member 22. A locking groove 2333a is opened on the groove wall of the fixing groove 3231a; the end of the traction member 22 is inserted into the fixing groove 3231a, and the locking pin 3232a is clamped in the locking groove 2333a, thereby limiting the relative position of the end of the traction member 22 and the seat body 321.

[0117] As can be understood, the fixing groove 3231a is used to accommodate the end of the traction member 22. The profile of the end of the traction member 22 is configured to match the groove wall of the fixing groove 3231a, thereby minimizing the gap between the end of the traction member 22 and the groove wall of the fixing groove 3231a, thereby improving the tightness of the fit between the two. After the locking pin 3232a passes through the end of the traction member 22 and is clamped into the locking groove 2333a, the relative position of the locking pin 3232a and the locking groove 2333a is fixed, thereby also fixing the relative position of the end of the traction member 22 and the fixing groove 3231a. As a result, the end of the traction member 22 is fixed to the base 321, and the end of the traction member 22 can move together with the base 321.

[0118] It should be noted that the opening direction of the locking groove 2333 a intersects with the opening direction of the fixing groove 3231 a , so that the locking pin 3232 a can prevent the end of the pulling member 22 from falling out of the fixing groove 3231 a .

[0119] Furthermore, as shown in FIG9 , the fixing structure 323 further includes a cover plate 324 disposed on the base body 321 , and the cover plate 324 is used to shield the fixing groove 3231 a and the locking groove 2333 a , thereby preventing the end of the traction member 22 from falling out of the notch of the fixing groove 3231 a .

[0120] The wall of the fixing groove 3231a can be configured to be straight or to have a certain bending angle, and the end of the pulling member 22 can also be configured to have a bending angle. The bending position of the pulling member 22 matches the bending position of the fixing groove 3231a, thereby improving the fit between the two and further preventing the end of the pulling member 22 from accidentally loosening.

[0121] The second type, please refer to Figures 11-a to 14-b, the fixing structure 323 includes a first fixing hole 3231b, a second fixing hole 3232b and a fixing member 3233b; the first fixing hole 3231b is opened at the end of the traction member 22, and the second fixing hole 3232b is opened on the seat body 321, and the fixing member 3233b passes through the first fixing hole 3231b and is locked in the second fixing hole 3232b, thereby fixing the end of the traction member 22 on the seat body 321.

[0122] It is understood that the first fixing hole 3231b is preferably configured as a through hole to allow the fixing member 3233b to be smoothly inserted. The second fixing hole 3232b can be configured to be provided with a thread, so that the second fixing hole 3232b and the fixing member 3233b are threadedly engaged. The second fixing hole 3232b and the fixing member 3233b can be configured to cooperate with each other through an interference fit, thereby also achieving fixation of the end of the traction member 22. The second fixing hole 3232b and the fixing member 3233b can also be connected by welding or gluing, thereby also achieving fixation of the end of the traction member 22.

[0123] Furthermore, as shown in FIG. 11 - a and FIG. 11 - b , the end portion of the traction member 22 is wound around the outer wall of the seat body 321 , and the first fixing hole 3231 b is aligned with the second fixing hole 3232 b .

[0124] It can be understood that the end of the traction member 22 is wound along the outer contour of the seat body 321, which can improve the fit, so that the traction member 22 including the end and the wound part are used to transmit the force together, which can avoid the problem of local force damage to a certain extent.

[0125] It should be noted that a groove or protrusion or other structure can be provided on the seat body 321 to guide the two to align with each other. Of course, with the assistance of the winding shape of the end of the traction member 22 itself, the adaptation between the contours can also quickly complete the assembly connection.

[0126] As shown in Figures 12-a to 14-b, in the implementation of the above-mentioned two fixing structures 323, the fixing structure 323 can be configured to further include a slot 3234b; the slot 3234b is located on the seat body 321, the second fixing hole 3232b is connected to the slot 3234b, and the traction member 22 is detachably inserted in the slot 3234b, so that the first fixing hole 3231b is aligned with the second fixing hole 3232b.

[0127] It can be understood that the groove wall profile of the slot 3234b is configured to adapt to the end of the traction member 22. After the end of the traction member 22 is inserted into the slot 3234b, the first fixing hole 3231b on the end of the traction member 22 will be aligned with the second fixing hole 3232b. Subsequently, the fixing member 3233b is correspondingly penetrated with the first fixing hole 3231b and the second fixing hole 3232b to complete the fixation of the end of the traction member 22.

[0128] The portion of the traction member 22 for inserting into the slot 3234b is preferably configured to be bent, so that a larger force can be generated after the end is inserted to prevent the end of the traction member 22 from accidentally falling out.

[0129] Preferably, the cross section of the base body 321 is circular, rectangular or oblong.

[0130] It can be understood that, as shown in FIG. 11 - a to FIG. 12 - b , the seat body 321 is configured as a cylinder, and the cross section of the seat body 321 is circular.

[0131] As shown in FIG. 14 - a and FIG. 14 - b , the base body 321 is configured as a rectangular column, and the cross section of the base body 321 is a rectangle.

[0132] As shown in FIG. 13 - a and FIG. 13 - b , the seat body 321 is formed into a flat columnar shape, and the cross section of the seat body 321 is an oblong shape.

[0133] Preferably, the corners of the seat body 321 are provided with rounded corners.

[0134] It can be understood that the rounded corners can prevent the edge of the seat body 321 from being damaged due to stress concentration.

[0135] In any of the above embodiments, no matter what implementation method is adopted for setting the fixed structure 323 or the seat body 321, the sliding member 32 can be configured to include a seat body 321, and the seat body 321 is not provided with a roller or a structure similar to a roller in structure and function. The seat body 321 is directly in contact with the sliding guide structure 31, and there is a sliding contact between the two, which can also guide the seat body 321 to slide along the guide track 33.

[0136] Of course, in any of the above embodiments, no matter what embodiment is adopted for setting the fixed structure 323 or the seat body 321, the sliding member 32 can also be configured to include a seat body 321 and a sliding wheel 322 arranged on the seat body 321, and the sliding wheel 322 is in contact with the sliding guide structure 31, so that the purpose of guiding the seat body 321 to slide along the guide track 33 can also be achieved.

[0137] As shown in Figures 3 to 7, in some embodiments of the stringing machine 10, the winding device 2 also includes a plurality of axles 23, each of which is rotatably arranged in the shell 1, and each axle 23 is distributed along the outer periphery of the wire drum 21. Each axle 23 has a rotating contact surface 233 for slidingly abutting against the traction member 22, and each rotating contact surface 233 is aligned with the accommodating groove 211.

[0138] As can be understood, the axle 23 is used to prevent the pulling member 22 from getting stuck outside the accommodating groove 211, thereby acting as a limiter. Furthermore, the rotatable arrangement of the axle 23 allows the axle 23 to guide the pulling member 22 to move in a predetermined direction within the wire drum 21. Each axle 23 is provided with a rotating contact surface 233, which is configured to directly contact the pulling member 22.

[0139] It should be noted that each rotating contact surface 233 is aligned with the receiving groove 211, so that when the traction member 22 deviates in the direction away from the receiving groove 211, it will preferentially contact the rotating contact surface 233 when contacting other structures, preventing the traction member 22 from being stuck by foreign objects.

[0140] Preferably, the distances from the center of each wheel axle 23 to the center of the wire drum 21 are configured to be equal.

[0141] Preferably, referring to FIG4 , the distance between the center of the wheel axle 23 and the center of the wire drum 21 gradually increases along the unwinding direction of the traction member. This can further guide the traction member 22 to gradually pass through the predetermined position on the housing 1. Of course, during the rewinding process, this embodiment can also play a role in guiding the traction member 22 to gradually rewind.

[0142] As shown in Figure 6, in some embodiments of the stringing machine 10, each wheel axle 23 includes a rotating shaft 231 and a wheel body 232. The rotating shaft 231 is rotatably arranged on the shell 1, and the wheel body 232 is sleeved on the rotating shaft 231. The rotating contact surface 233 is located on the wheel body 232, and the width W3 of the wheel body 232 corresponds to the width of the traction member.

[0143] It is understandable that the rotating shaft 231 is cylindrical in shape as a whole. The overall outer shape of the wheel body 232 is cylindrical, but it can also be configured to be tire-shaped or approximately tire-shaped. The width W3 of the wheel body 232 corresponds to the width of the accommodating groove 211, which means that the width W3 of the wheel body 232 is equal to the width of the accommodating groove 211. In this way, on the one hand, the rotating contact surface 233 of the wheel body 232 can fully correspond to each position in the width direction of the accommodating groove 211, preventing the traction member 22 from being unable to abut against the rotating contact surface 233 after being dislodged from a part of the accommodating groove 211. On the other hand, it also avoids the wheel body 232 being too large due to the width W3 of the wheel body 232 being too large and occupying too much space, thereby ensuring the overall compactness of the product.

[0144] It is particularly important to note that, in some embodiments, part of the wheel body 232 can be configured to be partially inserted into the accommodating groove 211 so that the traction member 22 is directly and completely confined in the accommodating groove 211, and the traction member 22 cannot escape from the notch of the accommodating groove 211.

[0145] As shown in FIG. 3 , in some embodiments of the stringing machine 10 , the limiting peripheral wall 11 is configured to include a plurality of spaced-apart convex walls, and each convex wall is spaced-apart from each axle 23 .

[0146] Understandably, first, the convex wall and the axle 23 together serve to limit the traction member 22. Furthermore, the effective contact area between the axle 23 and the traction member 22 is relatively small, and the cost of installing the axle 23 is higher than that of installing the limiting peripheral wall 11. Therefore, a certain number of axles combined with a certain number of convex walls can, on the one hand, reduce the friction force on the traction member 22 during the winding and unwinding process, and on the other hand, minimize the production cost of the product.

[0147] As shown in Figure 10, in some embodiments of the stringing machine 10, a traction port 12 is opened on the shell 1, and the traction port 12 is for the traction member 22 to be passed through; the stringing machine 10 also includes a guide device 4 (see Figures 1 to 5), please refer to Figure 10 again, the guide device 4 includes a guide wall 41 arranged in the shell 1 and a plurality of guide wheels 42 rotatably arranged in the shell 1, and a guide gap 43 is defined between each guide wheel 42; the traction member 22 slides against the guide wall 41, and the traction member 22 passes through the guide gap 43 and the traction port 12.

[0148] It is understood that the traction member 22 enters and exits the housing 1 through the traction opening 12 for retraction and unwinding. A structure for guiding the traction member 22 can be further provided outside the traction opening 12. For example, a guide cylinder 44 as shown in FIG10 can be further provided. The guide cylinder 44 is provided on the housing 1 and communicates with the traction opening 12. The provision of the guide cylinder 44 enables the traction member 22 to be retracted and unwound from a position more suitable for actual operation, improving operational convenience and preventing the traction member 22 from being stuck by the housing 1.

[0149] The guide device 4 is used to guide the traction member 22 between the spool 21 and the traction port 12, ensuring that the traction member 22 can be normally reeled and unreeled, and preventing the traction member 22 from getting stuck in the housing 1. When the traction member 22 has an expansion tendency, the guide wall 41 can support the traction member 22 in the expansion direction, playing a role of limiting and guiding.

[0150] The number of guide wheels 42 can be two, three, four, five, or more, and the guide wheels 42 collectively guide the traction member along a predetermined trajectory. The guide gap 43 is configured to conform to the contour of the traction member 22, thereby preventing the traction member 22 from excessively shaking within the guide gap 43.

[0151] As shown in FIG3 , FIG5 and FIG6 , in some embodiments of the stringing machine 10 , the winding device 2 further includes a driving member 24 , and the wire drum 21 includes a first rotating disk 212 , a second rotating disk 213 , and a ring body 214 located between the first rotating disk 212 and the second rotating disk 213 (the ring body 214 is shown in FIG7 );

[0152] The driving member 24 is connected to the first turntable 212 and the second turntable 213. The driving member 24 drives the first turntable 212 and the second turntable 213 to rotate at the same angular velocity. The ring body 214 is fixedly set on the first turntable 212 or the second turntable 213. The first turntable 212, the second turntable 213 and the ring body 214 jointly define the accommodating groove 211.

[0153] As will be understood, the driver 24 is used to output torque and can be configured as a motor, or as a pneumatic or hydraulically driven component commonly found in the prior art. The first and second rotating disks 212, 213 can be configured to rotate coaxially. They can be configured as brackets connected to the output shaft of the driver 24, or they can be driven by a gear transmission or belt transmission mechanism. The arrangement of the ring body 214 ensures that sufficient space is always reserved between the first and second rotating disks 212, 213 to accommodate the traction member 22.

[0154] The implementation of the present invention has the following beneficial effects:

[0155] The present invention relates to a wire threading machine, which sets the groove width of the accommodating groove to be equal to the width of the traction member, so that the traction member used for pulling the cable can only be wound in the accommodating groove in a single-row stacked manner, thereby avoiding the problem of the traction members being entangled or overlapping with each other on the line drum, and thus avoiding accidental deformation of the traction member.

[0156] By setting the sliding member and the sliding guide structure, the end of the traction member located in the accommodating groove will gradually move toward the periphery of the wire drum during the unwinding process, so that the traction member is as close to or fits as possible to the periphery of the wire drum. In this way, the traction member can be sent out in a direction tangent to the outer periphery of the wire drum as much as possible, so that the side of the traction member can be effectively supported, thereby preventing the traction member from bending due to excessive resistance during the unwinding process.

[0157] The scheme of the present invention has been described in detail above with reference to the accompanying drawings. In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

In addition, it is understood that the steps in the method of the embodiment of the present invention can be adjusted in order, merged and deleted according to actual needs, and the modules in the device of the embodiment of the present invention can be merged, divided and deleted according to actual needs.

[0158] While various embodiments of the present invention have been described above, the above descriptions are intended to be illustrative, non-exhaustive, and not limited to the disclosed embodiments.
