Description

Technical Field

[0001] This invention relates to the field of cable winding technology, and in particular to a non-adhesive cable reel and winding equipment. Background Technology

[0002] Cable reels are load-bearing components used for winding cables, and winding equipment is an accessory to extruders. (Reference) Figure 1 and Figure 2 Traditional winding equipment typically includes a frame 10, a rotating shaft 11, a winding wheel 12, and a linear drive mechanism 13. The cable reel includes a cylinder 100 with a first side plate 110 and a second side plate 120 connected to its left and right ends, respectively.

[0003] Before winding begins, the worker first places the cable reel's cylinder 100 onto the rotating shaft 11. At this time, the linear drive mechanism 13 has already positioned the winding wheel 12 in the starting position above the first side plate 110. The worker then attaches the first end of the cable 20 to the cylinder 100 near the first side plate 110, preparing for the winding operation. (Reference) Figure 2 After the equipment is started, the rotating shaft 11 drives the cable reel to rotate continuously, while the linear drive mechanism 13 drives the winding wheel 12 to reciprocate along the axial direction of the cylinder 100. The moving speed of the winding wheel 12 is strictly matched with the rotation speed of the rotating shaft 11, so that the cable reel is gradually wound around the cylinder 100 to form multiple layers. The distance sensor on the frame 10 monitors the radius of the cable reel in real time. When the radius of the cable reel is detected to be close to the preset value (i.e., the penultimate layer is about to be fully wound), the winding wheel 12 is exactly at the starting position above the first side plate 110, and then begins to wind the last layer of cable 20. During the winding of the last layer of cable 20, the moving speed of the winding wheel 12 is dynamically matched with the rotation speed of the rotating shaft 11, ensuring that the cable 20 is evenly arranged to the right, starting from the first side plate 110, and finally completed at the second side plate 120, at which point the radius of the cable reel reaches the preset value. After the final winding is completed, the rotating shaft 11 and the linear drive mechanism 13 continue to operate briefly. The linear drive mechanism 13 drives the winding wheel 12 to continue moving to the right from the position of the second side plate 120. Finally, the worker cuts the cable 20 between the winding wheel 12 and the cable roll, and glues the tail of the cable 20 to the surface of the cable roll near the second side plate 120 to complete the finishing. This method of fixing the tail of the cable 20 by gluing is relatively cumbersome. After cutting the cable 20, the worker needs to quickly find the gluing position. If the action is slightly slow, or if the tail of the cable 20 is briefly left unattended, the cable roll is very likely to loosen, which will affect the winding effect of the cable roll. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a non-adhesive cable reel, which can eliminate the step of adhering the cable tail section, thereby achieving rapid fixation of the cable tail section and thus helping to ensure the winding effect of the cable reel.

[0005] The present invention also proposes a winding device having the above-mentioned adhesive-free cable reel.

[0006] According to a first aspect of the present invention, a non-adhesive cable reel includes a cylindrical body, with a first side plate and a second side plate respectively provided at its left and right ends; a winding side plate disposed on the side of the second side plate facing the first side plate, the winding side plate being coaxially arranged with the second side plate, the radius of the winding side plate being smaller than the radius of the second side plate, the cylindrical body between the first side plate and the winding side plate being used for winding cables, and the outer wall of the winding side plate being used for winding the last layer of cables; and a wire pressing mechanism disposed on the second side plate, the wire pressing mechanism being used to press the cables tightly against the outer wall of the winding side plate.

[0007] It has at least the following beneficial effects:

[0008] During the final layer of cable winding, the winding wheel moves to the right, causing the cable to be evenly distributed to the right, starting from the first side plate, round after round, until the final round of the last layer is completed. At this point, the winding wheel is positioned directly above the winding side plate. The shaft then continues to rotate the cable reel, and the linear drive mechanism drives the winding wheel to continue moving to the right. Because the winding wheel remains in contact with the cable and the cable has a certain tension, the cable follows the winding wheel to the right as it continues to move, naturally winding around the outer wall of the winding side plate as it rotates. The winding wheel continues to move to the right until it reaches the right side of the second side plate, at which point the shaft and linear drive mechanism stop. The worker cuts the cable between the pressing mechanism and the winding wheel, and then the pressing mechanism presses and secures the resulting cable tail to the outer wall of the winding side plate. After the last layer and last turn of cable are wound, as the winding wheel continues to move to the right and the cable reel continues to rotate, the cable is wound onto the outer wall of the winding side plate under tension. After the worker cuts the cable between the pressing mechanism and the winding wheel, the tail of the cable is pressed and fixed to the outer wall of the winding side plate by the pressing mechanism. This eliminates the time difference caused by finding the bonding position after cutting the cable, and eliminates the possibility of the cable tail becoming loose when no one is pulling it. It replaces the step of bonding the cable tail, avoids the cable roll from becoming loose, and thus ensures the winding effect of the cable roll.

[0009] According to a first aspect of the present invention, the non-adhesive cable reel includes a pressing rod, and a waist-shaped groove is provided on the side of the second side plate facing the first side plate. The pressing rod is movably connected to the second side plate, and the waist-shaped groove is used to receive the pressing rod. The pressing rod can extend out from the waist-shaped groove and press the cable against the outer wall of the winding side plate.

[0010] According to a first aspect of the present invention, the non-adhesive cable reel, the pressing mechanism further includes an elastic element and a damping element. The waist-shaped groove extends radially along the second side plate. The damping element is movably connected to the second side plate and is capable of moving radially inward or outward along the second side plate. The pressing rod is connected to the output end of the damping element. The elastic element is used to drive the damping element to move radially inward along the second side plate. The damping element is used to drive the pressing rod to move toward the first side plate. The pressing rod is held against the side of the winding side plate away from the first side plate and is housed in the waist-shaped groove. The damping element is in a compressed state. The damping element moves radially outward along the second side plate. The pressing rod disengages from the abutment with the winding side plate. The damping element drives the pressing rod to extend out of the waist-shaped groove so that the pressing rod extends to the outside of the cable wound on the outer wall of the winding side plate and presses the cable against the outer wall of the winding side plate.

[0011] According to a first aspect of the present invention, the non-adhesive cable reel further includes a trigger member, the elastic member being a torsion spring, the trigger member having a trigger end and a connecting end, the middle portion of the trigger member being hinged to the second side plate, the trigger end of the trigger member being located on the outer side of the outer wall of the winding side plate, the connecting end of the trigger member being drivenly connected to the damping member, the torsion spring being used to drive the connecting end of the trigger member to swing inward, when the trigger end of the trigger member is pressed by a cable wound on the outer wall of the winding side plate, the connecting end of the trigger member drives the damping member to move radially outward along the second side plate, so that the pressure rod disengages from the abutment with the winding side plate, the damping member drives the pressure rod to extend outward from the waist-shaped groove, the pressure rod extending to the outer side of the cable wound on the outer wall of the winding side plate, after the cable is cut, the connecting end of the trigger member drives the damping member to move radially inward along the second side plate, so that the pressure rod presses the cable tightly against the outer wall of the winding side plate.

[0012] According to a first aspect of the present invention, in the non-adhesive cable reel, a limiting block is provided on the side of the winding side plate away from the first side plate, the limiting block extends into the waist-shaped groove, and the pressure rod can abut against the limiting block to increase the travel of the pressure rod extending out of the waist-shaped groove.

[0013] According to a first aspect of the present invention, the adhesive-free cable reel further includes a connecting rod, the connecting rod being parallel to the radial direction of the second side plate, one end of the connecting rod being connected to the damping member, and the other end of the connecting rod being provided with a transmission post, the connecting end of the trigger member being provided with a transmission waist-shaped hole, and the transmission post passing through the transmission waist-shaped hole.

[0014] According to a first aspect of the present invention, the adhesive-free cable reel further includes a fixing member disposed on the first side plate and located close to the cylindrical body, the cylindrical body being used to fix the beginning end of the cable.

[0015] According to a first aspect of the present invention, the non-adhesive cable reel is a gland head, which is disposed on the side of the first side plate away from the second side plate. The first side plate is provided with a cable passage hole, which is disposed close to the cylinder. The cable passage hole communicates with a through hole on the gland head. The cable passage hole and the through hole on the gland head are used to allow the cable head to pass through, so that the gland head can clamp the cable head.

[0016] According to a second aspect of the present invention, a winding device includes a frame, a rotating shaft, a winding wheel, a linear drive mechanism, and a non-adhesive cable reel according to the first aspect of the present invention described above.

[0017] It has at least the following beneficial effects: This winding equipment has all the beneficial effects brought about by the above-mentioned non-adhesive cable reels, which will not be repeated here.

[0018] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0039] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0040] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0041] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0042] refer to Figure 1 and Figure 2 It should be explained that multi-turn, multi-layered cable rolls are a common structure formed during the winding process of cable 20. Multi-turn refers to the continuous winding of cable 20 around the cylindrical body 100 of the cable reel within the same layer, with one tightly arranged turn after another, extending from the first side plate 110 towards the second side plate 120 or from the second side plate 120 towards the first side plate 110, forming a complete circular arrangement; multi-layered means that after one layer of cable 20 has filled the cylindrical body 100, a new layer is continued to be wound on top of it, so that the cable 20 is accumulated layer upon layer, eventually forming a cable roll with a radius that increases with the number of layers.

[0043] refer to Figure 2 It should be explained that after the last turn of cable 20 is wound, the linear drive mechanism 13 drives the winding wheel 12 to continue moving to the right side of the second side plate 120 from its position to create safe and convenient conditions for the final winding. Firstly, moving the winding wheel 12 to the right side of the second side plate 120 allows for a straight, unobstructed transition section between the winding wheel 12 and the cable roll, facilitating clear observation and precise cutting of this section of cable 20 by the worker, avoiding damage to the wound cable roll during cutting. Secondly, moving the winding wheel 12 to the right side of the second side plate 120 reduces the impact of cable 20 tension fluctuations when the winding equipment stops on the winding of the last few turns of cable 20, and also provides sufficient space for subsequent removal of the cable reel from the left end of the shaft 11, preventing collisions between the cable reel and the winding wheel 12 during removal. On the other hand, if the winding wheel 12 stops at any position after the cable reel reaches the preset radius, the cut end of the cable 20 will deviate from the first side plate 110 or the second side plate 120 of the cable reel body 100. If the winding wheel 12 stops above the middle of the body 100, the cut end of the cable 20 will be stuck to the middle of the cable reel, resulting in uneven edges of the cable reel and affecting the winding effect of the cable reel.

[0044] refer to Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 10This invention discloses a non-adhesive cable reel, comprising a cylindrical body 100, a winding side plate 130, and a wire pressing mechanism 400. A first side plate 110 and a second side plate 120 are respectively provided at the left and right ends of the cylindrical body 100.

[0045] A winding side plate 130 is disposed on the side of the second side plate 120 facing the first side plate 110, and the winding side plate 130 is located between the first side plate 110 and the second side plate 120. In this embodiment of the invention, the winding side plate 130, the first side plate 110, and the second side plate 120 are all circular plates. The central axes of the winding side plate 130, the first side plate 110, the second side plate 120, and the cylinder 100 all coincide. The first side plate 110 and the second side plate 120 have the same radius, and the radius of the winding side plate 130 is smaller than the radius of the second side plate 120. The outer wall of the winding side plate 130 is used for winding the last turn of the cable 20 of the last layer. In this embodiment of the invention, the distance from the central axis of the cylinder 100 to the outer surface of the cable roll is the radius of the cable roll.

[0046] The wire pressing mechanism 400 is disposed on the second side plate 120. After the last layer of cable 20 is wound around the outer wall of the winding side plate 130, the wire pressing mechanism 400 can press the last layer of cable 20 tightly onto the outer wall of the winding side plate 130. The cable 20 between the wire pressing mechanism 400 and the winding wheel 12 is used to be cut. As an embodiment of the present invention, the wire pressing mechanism 400 includes a first magnetic suction member and a second magnetic suction member. The first magnetic suction member is disposed on the outer wall of the winding side plate 130. After the last layer of cable 20 is wound on the outer wall of the winding side plate 130, the worker places the second magnetic suction member on the area of ​​the cable 20 corresponding to the first magnetic suction member, so that the second magnetic suction member and the first magnetic suction member attract each other. The second magnetic suction member can then press the cable 20 tightly onto the outer wall of the winding side plate 130. Finally, the worker cuts the cable 20 between the second magnetic suction member and the winding wheel 12. The resulting cable 20 tail section is then pressed and fixed by the second magnetic suction member, eliminating the step of gluing the cable 20 tail section.

[0047] Understandably, when the cable 20 needs to be wound up, the worker first places the cylinder 100 of the non-adhesive cable reel onto the rotating shaft 11 of the winding equipment. At this time, the linear drive mechanism 13 has already placed the winding wheel 12 in the starting position above the first side plate 110. After the worker fixes the beginning of the cable 20 to the cylinder 100 near the first side plate 110, the rotating shaft 11 and the linear drive mechanism 13 are activated. The rotating shaft 11 drives the cable reel to rotate continuously, and the linear drive mechanism 13 drives the winding wheel 12 to move back and forth along the axial direction of the cylinder 100, so that the winding wheel 12 moves back and forth between the first side plate 110 and the winding side plate 130. The moving speed of the winding wheel 12 matches the rotation speed of the rotating shaft 11, so that multiple layers of cable are gradually wound around the cylinder 100 between the first side plate 110 and the winding side plate 130. The distance sensor on the frame 10 monitors the radius of the cable reel on the cylinder 100 in real time. When the radius of the cable reel is detected to be close to the preset value (i.e., the penultimate layer is about to be fully wound), the winding wheel 12 is positioned at the starting position above the first side plate 110 and begins winding the last layer of cable 20. During the winding of the last layer of cable 20, the winding wheel 12 moves to the right, so that the cable 20 is evenly distributed to the right, starting from the first side plate 110, until the last turn of the last layer of cable 20 is completed. At this time, the winding wheel 12 is exactly above the winding side plate 130. Then the rotating shaft 11 continues to drive the cable reel to rotate, and the linear drive mechanism 13 drives the winding wheel 12 to continue to move to the right. Since the winding wheel 12 is in contact with the cable 20 and the cable 20 has a certain tension, the cable 20 will follow the winding wheel 12 to continue to move to the right as the winding wheel 12 continues to move to the right, so that the cable 20 is naturally wound around the outer wall of the winding side plate 130 as the winding side plate 130 rotates. The winding wheel 12 continues to move to the right until it reaches the right side of the second side plate 120, at which point the shaft 11 and the linear drive mechanism 13 stop. The worker cuts the cable 20 between the wire pressing mechanism 400 and the winding wheel 12, and then the wire pressing mechanism 400 presses and fixes the resulting cable 20 tail section onto the outer wall of the winding side plate 130. After the last layer and last turn of cable 20 are wound, as the winding wheel 12 continues to move to the right and in conjunction with the continuous rotation of the cable reel, the cable 20 is wound onto the outer wall of the winding side plate 130 under tension. After the worker cuts the cable 20 between the pressing mechanism 400 and the winding wheel 12, the tail end of the cable 20 is pressed and fixed to the outer wall of the winding side plate 130 by the pressing mechanism 400. This eliminates the time difference caused by finding the bonding position after cutting the cable 20, and prevents the possibility of the tail end of the cable 20 becoming loose when no one is pulling it. It replaces the step of bonding the tail end of the cable 20, avoids the cable roll from becoming loose, and thus ensures the winding effect of the cable roll.

[0048] In this embodiment of the invention, the radius of the winding side plate 130 is equal to the difference between the preset radius of the cable roll and the diameter of the cable 20, that is, the radius of the winding side plate 130 is equal to the preset radius of the cable roll minus the diameter of the cable 20. It is understood that during the winding process, when the cable 20 is wound multiple times and multiple layers onto the cylinder 100 between the first side plate 110 and the winding side plate 130 to form a cable roll, the radius of the cable roll will gradually approach the preset value. Since the radius of the winding side plate 130 is the preset value of the radius of the cable roll minus the diameter of the cable 20, when the last layer of cable 20 is wound to the winding side plate 130, the distance from the cable 20 wound on the outer wall of the winding side plate 130 to the central axis of the cylinder 100 is exactly matched with the preset value of the radius of the cable roll formed on the cylinder 100. This avoids the problem of the cable 20 stacking at the winding side plate 130 during the winding process due to the excessively large radius of the winding side plate 130, and also avoids the cable roll becoming loose due to the sudden drop in tension when the cable 20 is wound due to the excessively small radius of the winding side plate 130. On the other hand, the radius of the winding side plate 130 is equal to the preset radius of the cable roll minus the diameter of the cable 20, so that the cable 20 can be smoothly wound on the outer wall of the winding side plate 130. This avoids abrupt changes in the distance between the cable 20 wound on the outer wall of the winding side plate 130 and the central axis of the cylinder 100, so that the tension of the cable 20 can remain stable, avoiding additional stress or slack in the cable 20, thereby ensuring the winding effect of the cable roll.

[0049] refer to Figures 4 to 8 The wire pressing mechanism 400 includes a pressing rod 430. A waist-shaped groove 121 is provided on the side of the second side plate 120 facing the first side plate 110 (i.e., the left side of the second side plate 120). The pressing rod 430 is movably connected to the second side plate 120. The waist-shaped groove 121 is used to house the pressing rod 430, which can extend from the waist-shaped groove 121 and press the cable 20 against the outer wall of the winding side plate 130. It is understood that during the winding of the cable 20, the pressing rod 430 is housed within the waist-shaped groove 121 on the second side plate 120 to avoid interfering with the winding of the cable 20. After the last layer of cable 20 is wound around the outer wall of the winding side plate 130, the pressing rod 430 extends from the waist-shaped groove 121 and presses the cable 20 against the outer wall of the winding side plate 130. As an embodiment of the present invention, one end of the pressure rod 430 is hinged to the inner wall of the waist-shaped groove 121. A motor is provided on the second side plate 120. The motor is used to drive the pressure rod 430 to swing, so that the pressure rod 430 can be stored in the waist-shaped groove 121, and also so that the pressure rod 430 can swing out from the waist-shaped groove 121 and press the cable 20 tightly against the outer wall of the winding side plate 130.

[0050] refer to Figures 4 to 8The pressing mechanism 400 also includes an elastic element 410 and a damping element 420. A waist-shaped groove 121 extends radially along the second side plate 120. The damping element 420 is movably connected to the second side plate 120 and can move radially inward or outward along the second side plate 120. The pressing rod 430 is connected to the output end of the damping element 420. The elastic element 410 drives the damping element 420 to move radially inward along the second side plate 120, and the damping element 420 drives the pressing rod 430 towards the first side plate 110. In other words, the damping element 420 drives the pressing rod 430... 30 moves to the left, the pressure rod 430 abuts against the side of the winding side plate 130 away from the first side plate 110 and is housed in the waist-shaped groove 121, the damping member 420 is in a compressed state, the damping member 420 moves outward along the radial direction of the second side plate 120, the pressure rod 430 disengages from the abutment with the winding side plate 130, the damping member 420 drives the pressure rod 430 to extend out of the waist-shaped groove 121, so that the pressure rod 430 extends to the outside of the cable 20 wound on the outer wall of the winding side plate 130, and the pressure rod 430 presses the cable 20 tightly against the outer wall of the winding side plate 130.

[0051] In one embodiment of the present invention, the elastic element 410 can be a tension spring, with its two ends connected to the damping element 420 and the second side plate 120, respectively. The tension spring can apply tension to the damping element 420, thereby driving the damping element 420 and the pressure rod 430 to move toward the cylinder 100. It should be noted that, in this embodiment of the present invention, moving radially toward the cylinder 100 along the second side plate 120 is considered inward movement, and moving radially away from the cylinder 100 along the second side plate 120 is considered outward movement.

[0052] In this embodiment of the invention, the damping element 420 is a common elastic damping element, which includes a compression spring, a push rod 423, and a housing. The housing is movably connected to the second side plate 120. One end of the push rod 423 is connected to the pressure rod 430, and the other end extends into the housing and abuts against the compression spring. When the pressure rod 430 abuts against the side of the winding side plate 130 away from the first side plate 110, and the pressure rod 430 is retracted into the waist-shaped groove 121, the push rod 423 connected to the pressure rod 430 retracts into the housing. The compression spring located in the housing is compressed by the push rod 423 and stores elastic potential energy. The friction pair between the outer wall of the push rod 423 and the inner wall of the housing remains in abutment. At this time, the damping element is in a compressed state. When the pressure rod 430 and damping element 420 move outward, and the pressure rod 430 disengages from the winding side plate 130, the compression spring inside the housing begins to return to its original state. During this process, the compression spring releases elastic potential energy, generating an outward thrust on the push rod 423. The push rod 423 then begins to move towards the first side plate 110, pushing the pressure rod 430 towards the first side plate 110. During the movement of the push rod 423, the friction pair between the outer wall of the push rod 423 and the inner wall of the housing generates a reverse damping force. This damping force slows down the movement speed of the push rod 423 and the pressure rod 430, prolonging the time it takes for the pressure rod 430 to extend out of the waist-shaped groove 121. This allows the pressure rod 430 to slowly move to the left, extending out of the waist-shaped groove 121 and reaching the outside of the winding side plate 130.

[0053] Understandably, the elastic element 410 can always apply a force close to the cylinder 100 to the damping element 420, so that the pressure rod 430 and the damping element 420 always tend to move closer to the cylinder 100. The damping element 420 can always apply a thrust (i.e., a leftward thrust) towards the first side plate 110 to the pressure rod 430. During the winding process of the cable 20, the pressure rod 430 is housed in the waist-shaped groove 121, and under the action of the elastic element 410 and the damping element 420, one end of the pressure rod 430 can always be kept in contact with the side of the winding side plate 130 away from the first side plate 110. At this time, the damping element 420 is in a compressed state. As the winding process proceeds, once the cable 20 is wound on the outer wall of the winding side plate 130, and the winding wheel 12 moves to the right side of the second side plate 120 while the rotating shaft 11 and linear drive mechanism 13 stop, the worker drives the damping element 420 to move rapidly outward. The pressure rod 430 then moves outward within the waist-shaped groove 121, disengaging from its contact with the winding side plate 130 and moving to the outside of the wound cable 20 on the winding side plate 130. Under the damping characteristics of the damping element 420 itself, the damping element 420 drives the pressure rod 430 to extend out of the waist-shaped groove 121 and to the outside of the cable 20 wound on the outer wall of the winding side plate 130. At this point, the cable 20 is located between the winding side plate 130 and the pressure rod 430. Next, the worker cuts the cable 20 between the pressure rod 430 and the winding reel 12 and releases the damping element 420. Under the action of the elastic element 410, the damping element 420 and the pressure rod 430 move inward, thereby allowing the pressure rod 430 to press the tail end of the cable 20 tightly against the outer wall of the winding side plate 130. Before winding, the non-adhesive cable reel is in an empty state. The worker can press the pressure rod 430 into the waist-shaped groove 121 and move the damping element 420 and the pressure rod 430 inward, so that one end of the pressure rod 430 is once again in contact with the side of the winding side plate 130 away from the first side plate 110.

[0054] refer to Figure 4 , Figure 5 , Figure 6 and Figure 10The non-adhesive cable reel also includes a trigger element 200, an elastic element 410 which is a torsion spring, a mounting cavity formed in the winding side plate 130, and a mounting opening 131 communicating with the mounting cavity on the outer wall of the winding side plate 130. The trigger element 200 has a trigger end 210 and a connecting end 220. The middle part of the trigger element 200 is hinged to the second side plate 120. The connecting end 220 of the trigger element 200 is located in the mounting cavity. The trigger end 210 of the trigger element 200 extends out from the mounting opening 131 so that the trigger end 210 of the trigger element 200 is located on the outer side of the outer wall of the winding side plate 130. The connecting end 220 of the trigger element 200 is connected to the damping element 420. The torsion spring is used to drive the connecting end 220 of the trigger element 200 to swing inward. When the trigger end 210 of the trigger 200 is pressed by the cable 20 wound on the outer wall of the winding side plate 130, the connecting end 220 of the trigger 200 drives the damping member 420 to move radially outward along the second side plate 120, so that the pressure rod 430 disengages from the abutment of the winding side plate 130. The damping member 420 drives the pressure rod 430 to extend out of the waist-shaped groove 121. The pressure rod 430 extends to the outside of the cable 20 wound on the outer wall of the winding side plate 130. After the cable 20 between the pressure rod 430 and the winding wheel 12 is cut, the connecting end 220 of the trigger 200 drives the damping member 420 to move radially inward along the second side plate 120, so that the pressure rod 430 presses the cable 20 tightly against the outer wall of the winding side plate 130.

[0055] It should be explained that when the connecting end 220 of the trigger 200 swings inward toward the cylinder 100, it means that the connecting end 220 swings inward; when the connecting end 220 of the trigger 200 swings outward away from the cylinder 100, it means that the connecting end 220 swings outward.

[0056] In this embodiment of the invention, the trigger 200 is similar to a lever structure. The middle part of the trigger 200 is hinged to the second side plate 120 via a hinge shaft. A torsion spring is sleeved on the hinge shaft, and the two elastic arms of the torsion spring are respectively connected to the trigger 200 and the second side plate 120. The two ends of the trigger 200 are a trigger end 210 and a connecting end 220, respectively. The connecting end 220 of the trigger 200 is connected to the damping member 420 in a transmission manner, and the torsion spring provides the oscillating power for the trigger 200. A limiting structure is provided on the trigger end 210 of the trigger 200, which can abut against the inner wall of the mounting cavity. Under normal conditions, when the trigger end 210 of the trigger 200 is not pressed, the connecting end 220 of the trigger 200 always tends to swing inward under the force of the torsion spring. At this time, the trigger end 210 of the trigger 200 extends out of the mounting port 131 on the outer wall of the winding side plate 130, the limiting structure on the trigger end 210 abuts against the inner wall of the mounting cavity, and at this time the pressure rod 430 abuts against the winding side plate 130 and is housed in the waist-shaped groove 121, and the damping member 420 is in a compressed state.

[0057] Understandably, during the process of the cable 20 being wound around the outer wall of the winding side plate 130, the cable 20, maintaining tension, will press the trigger end 210 of the trigger member 200, causing the trigger member 200 to swing around the central hinge point. The connecting end 220 of the trigger member 200 will then swing outward, thereby causing the connecting end 220 of the trigger member 200 to drive the damping member 420 and the pressure rod 430 to move outward. The pressure rod 430 disengages from the winding side plate 130 and, under the action of the damping characteristics of the damping member 420 itself, moves to the left and extends from the waist-shaped groove 121 to the outside of the wound cable 20. After the winding wheel 12 moves to the right side of the second side plate 120 and the rotating shaft 11 and linear drive mechanism 13 stop, the worker cuts the cable 20 between the winding wheel 12 and the pressure rod 430. The pressure of the cable 20 on the trigger end 210 disappears. Under the action of the torsion spring, the connecting end 220 of the trigger 200 swings inward, causing the connecting end 220 of the trigger 200 to drive the damping element 420 and the pressure rod 430 to move inward. This causes the pressure rod 430 to move towards the outer wall of the winding side plate 130, thus pressing and fixing the tail end of the cable 20 onto the outer wall of the winding side plate 130. During the process of the cable 20 winding around the outer wall of the winding side plate 130, the cable 20 can press the trigger end 210 of the trigger 200 to realize the automatic movement of the damping element 420 and the pressure rod 430, replacing the operation of the worker to drive the damping element 420. When the cable 20 is wound to the trigger end 210 of the trigger member 200, the pressure of the cable 20 on the trigger end 210 triggers the damping member 420 and the pressure rod 430 to move outward, ensuring that the pressure rod 430 disengages from the winding side plate 130 and extends out of the waist-shaped groove 121 at the appropriate time. After the cable 20 between the pressure rod 430 and the winding wheel 12 is cut, the torsion spring drives the trigger member 200 to swing, causing the damping member 420 and the pressure rod 430 to move inward automatically, so as to achieve the clamping and fixing of the tail section of the cable 20 by the pressure rod 430, thereby reducing manual intervention and simplifying the operation process of clamping and fixing the tail section of the cable 20.

[0058] It should be explained that after the trigger end 210 of the trigger 200 is pressed by the cable 20, the trigger end 210 of the trigger 200 can extend into the mounting cavity; after the cable 20 between the pressure rod 430 and the winding wheel 12 is cut, the torsion spring drives the trigger 200 to swing, so that the trigger end 210 of the trigger 200 extends out from the mounting port 131 and out from the outer wall of the winding side plate 130. At this time, the limiting structure on the trigger end 210 abuts against the inner wall of the mounting cavity to ensure that the trigger 200 will not swing before being pressed. In this embodiment of the invention, the waist-shaped groove 121 provides sufficient space for the pressure rod 430 to move, allowing it to reach the outer area of ​​the wound cable 20 during its movement within the groove 121. This prevents the pressure rod 430 from being blocked by the cable 20 or the winding side plate 130 due to insufficient travel, thus avoiding it failing to reach its designated position. Furthermore, the design of the trigger 200 ensures that the pressure rod 430 and the damping element 420 have sufficient distance to move to the outer area of ​​the wound cable 20. This ensures that after the pressure rod 430 fully extends from the waist-shaped groove 121, it can remain outside the cable 20 wound on the outer wall of the winding side plate 130 (i.e., the cable 20 is located between the pressure rod 430 and the outer wall of the winding side plate 130). It should be noted that, along the rotation direction of the shaft 11, the cable 20 is first wound around the pressure rod 430 before the trigger end 210 of the trigger 200 is pressed.

[0059] refer to Figure 4 A limiting block 132 is provided on the side of the winding side plate 130 away from the first side plate 110. The limiting block 132 extends into the waist-shaped groove 121. The depth of the waist-shaped groove 121 is greater than the length of the pressure rod 430. The pressure rod 430 can abut against the limiting block 132 to increase the travel of the pressure rod 430 as it extends out of the waist-shaped groove 121. It can be understood that during the process of the cable 20 being wound around the outer wall of the winding side plate 130, when the trigger end 210 of the trigger member 200 is pressed by the cable 20, the connecting end 220 of the trigger member 200 will drive the damping member 420 and the pressure rod 430 to move outward, causing the pressure rod 430 to disengage from the abutment of the limiting block 132. Because the depth of the waist-shaped groove 121 is greater than the length of the pressure rod 430, and the limiting block 132 extends into the waist-shaped groove 121 and abuts against one end of the pressure rod 430, the limiting block 132 limits the position of the pressure rod 430 within the waist-shaped groove 121, allowing the pressure rod 430 to have a sufficiently large travel. This ensures that after the pressure rod 430 disengages from the limiting block 132, it maintains a safe distance from the cable 20 wound on the winding side plate 130 during its extension. Without the limiting effect of the limiting block 132, the travel of the pressure rod 430 would be too small, causing it to quickly approach the cable 20 wound on the winding side plate 130 after disengaging from the limiting block. This would exert a pushing force on the cable 20, disrupting its winding trajectory and tension stability.

[0060] On the other hand, the travel of the pressure rod 430 is increased so that it can fully extend from the waist-shaped groove 121 only after it has moved to the outer area of ​​the cable 20. When the pressure rod 430 and the damping member 420 begin to move outward, the pressure rod 430 is located in the waist-shaped groove 121 under the abutment of the limiting block 132 and moves synchronously with the damping member 420. After the pressure rod 430 disengages from the limiting block 132, the damping member 420 drives the pressure rod 430 to move at a lower speed. In the initial stage of the movement of the pressure rod 430, the pressure rod 430 is still located in the waist-shaped groove 121, which avoids interference between the pressure rod 430 and the cable 20 before reaching the designated position (i.e., the outer side of the cable 20), ensuring that the pressure rod 430 can cross the position of the cable 20. After the pressure rod 430 moves with the damping element 420 to the outer area of ​​the cable 20, thanks to the greater depth of the waist-shaped groove 121 than the length of the pressure rod 430, and the travel space provided by the limiting block 132, the pressure rod 430 extends completely from the waist-shaped groove 121 and accurately reaches the predetermined position on the outer side of the cable 20. This ensures that the pressure rod 430 will not interfere with the cable 20 during movement, and can form an effective pressing posture after it is in place. Before winding, the non-adhesive cable reel is in an empty state. The worker can press the pressure rod 430 into the waist-shaped groove 121 and move the damping element 420 and the pressure rod 430 inward, so that one end of the pressure rod 430 abuts against the limiting block 132 again.

[0061] refer to Figure 4 and Figure 6 The inner bottom wall of the waist-shaped groove 121 is provided with a guide waist-shaped hole 122. One end of the damping member 420 passes through the guide waist-shaped hole 122. The guide waist-shaped hole 122 is parallel to the radial direction of the second side plate 120. The damping member 420 is provided with a limiting protrusion 421 and a nut 422. The nut 422 is threadedly connected to the outer wall of the damping member 420. The limiting protrusion 421 is located in the waist-shaped groove 121 and can abut against the inner bottom wall of the waist-shaped groove 121. The nut 422 is located on the right side of the second side plate 120 and can abut against the second side plate 120. Specifically, the limiting protrusion 421 is located on the outer wall of the housing, and the nut 422 is threadedly connected to the outer wall of the housing. Understandably, the limiting protrusion 421 and the nut 422 limit the damping element 420, preventing the damping element 420 from coming out of the guide waist-shaped hole 122, and ensuring that the damping element 420 can move along the guide waist-shaped hole 122, so as to realize the damping element 420 moving radially inward or outward along the second side plate 120.

[0062] refer to Figure 5 and Figure 6The adhesive-free cable reel also includes a connecting rod 300, which is parallel to the radial direction of the second side plate 120. One end of the connecting rod 300 is connected to the damping member 420, and the other end of the connecting rod 300 is provided with a transmission post 310. The connecting end 220 of the trigger member 200 is provided with a transmission waist-shaped hole 221, and the transmission post 310 passes through the transmission waist-shaped hole 221. It can be understood that the transmission post 310 on the other end of the connecting rod 300 passes through the transmission waist-shaped hole 221 on the connecting end 220, and the guide waist-shaped hole 122 provides a suitable movement space for the damping member 420. When the trigger 200 swings around the central hinge point, the connecting end 220 of the trigger 200 will generate an arc-shaped trajectory. The transmission column 310 slides with the transmission waist-shaped hole 221, and the inner wall of the transmission waist-shaped hole 221 can abut against the transmission column 310, so that the arc-shaped swing of the trigger 200 is converted into a linear force along the axial direction of the connecting rod 300. This causes the connecting rod 300 to drive the damping element 420 and the pressure rod 430 to move radially inward or outward along the second side plate 120, realizing the transmission connection between the connecting end 220 of the trigger 200 and the damping element 420. In this embodiment of the invention, the end of the waist-shaped groove 121 near the cylinder 100 is connected to the mounting cavity, and the transmission column 310 extends into the mounting cavity. In this embodiment of the invention, one end of the connecting rod 300 is connected to the limiting protrusion 421 on the damping element 420.

[0063] In this embodiment of the invention, the width of the winding side plate 130 is greater than the diameter of the cable 20. The width of the winding side plate 130 is its axial dimension along the cylinder 100. When the cable 20 is wound around the outer wall of the winding side plate 130, the cable 20 will occupy a certain space along the axial direction of the winding side plate 130. Because the width of the winding side plate 130 is greater than the diameter of the cable 20, the cable 20 can be stably wound within the width range of the winding side plate 130 during the winding process, so that the winding area of ​​the cable 20 can completely cover the trigger end 210 of the trigger member 200, so that the cable 20 can form sufficient contact with the trigger end 210 of the trigger member 200 during the winding process, thereby ensuring that the cable 20 can smoothly press the trigger end 210 of the trigger member 200. Reference Figure 11 In another embodiment of the present invention, the adhesive-free cable reel includes two wire pressing mechanisms 400, two trigger elements 200, and two connecting rods 300. The two connecting rods 300 are symmetrical about the central axis of the cylinder 100, the two wire pressing mechanisms 400 are symmetrical about the central axis of the cylinder 100, and the two trigger elements 200 are symmetrical about the central axis of the cylinder 100. It is understood that the two trigger elements 200 are respectively arranged corresponding to the two wire pressing mechanisms 400 to ensure that at least one set of trigger elements 200 and wire pressing mechanisms 400 can achieve the clamping and fixing of the cable 20. Further details are omitted here.

[0064] refer to Figure 9The non-adhesive cable reel also includes a fixing member 111, which is located on the first side plate 110 and close to the cylinder 100, which is used to fix the beginning of the cable 20. It should be explained that traditionally, before winding the cable 20, the beginning of the cable 20 needs to be glued to the cylinder 100 near the first side plate 110. This is not only cumbersome but also prone to adhesive failure, leading to loosening of the cable 20's beginning. The fixing member 111 secures the beginning of the cable 20, replacing the traditional method of gluing the cable 20's beginning, eliminating the need for manual gluing, simplifying the operation, and preventing the cable 20's beginning from becoming loose. In this embodiment of the invention, the fixing member 111 is a gland head, which is located on the side of the first side plate 110 away from the second side plate 120. The first side plate 110 has a wire-passing hole, which is located near the cylinder 100 and communicates with a through hole on the gland head. The wire-passing hole and the through hole on the gland head are used for the cable 20 to pass through, so that the gland head can clamp the cable 20. It should be explained that the gland head is a common connector used to fix and seal the cable 20. The gland head includes a base with internal threads and a pressure cap with external threads. A sealing ring is provided between the base and the pressure cap. The center of the base has a through hole for the cable 20 to pass through. It can be understood that the gland head is located on the side of the first side plate 110 away from the second side plate 120, and the first side plate 110 has a wire-passing hole near the cylinder 100, which communicates with the through hole of the gland head. When it is necessary to clamp the beginning of the cable 20, the worker first passes the beginning of the cable 20 through the cable hole and the through hole of the gland in sequence, so that the beginning of the cable 20 extends out of the first side plate 110. Then, the gland cap is tightened. The cap squeezes the sealing ring in the base through the threaded engagement. After the sealing ring is deformed by the force, it tightly wraps around and clamps the beginning of the cable 20, thus achieving non-adhesive clamping and fixing of the beginning of the cable 20.

[0065] refer to Figure 12The present invention also discloses a winding device, including a frame 10, a rotating shaft 11, a winding reel 12, a linear drive mechanism 13, and a non-adhesive cable reel. The rotating shaft 11 is rotatably connected to the frame 10, and the non-adhesive cable reel is sleeved on the rotating shaft 11. The rotating shaft 11 is used to drive the non-adhesive cable reel to rotate. It is understood that when the cable 20 needs to be wound, the worker can sleeve the cylinder 100 of the non-adhesive cable reel on the rotating shaft 11. After the fixing member 111 of the non-adhesive cable reel has completed clamping the beginning end of the cable 20, the worker can start the winding device to make the rotating shaft 11 drive the non-adhesive cable reel to rotate. After the non-adhesive cable reel starts to rotate, the cable 20 is wound around the cylinder 100 between the first side plate 110 and the winding side plate 130. The linear drive mechanism 13 is mounted on the frame 10. The winding wheel 12 is rotatably connected to the output end of the linear drive mechanism 13. The limiting ring groove on the outer wall of the winding wheel 12 is used for the cable 20 to extend into, and the cable 20 is wound around the inner bottom wall of the limiting ring groove. The linear drive mechanism 13 is used to drive the winding wheel 12 to move back and forth in the left and right directions. Further details are omitted here.
