Description

Technical Field

[0001] This utility model relates to the field of curved wire winding machine technology, specifically a novel constant tension curved wire winding machine. Background Technology

[0002] Patent CN220664514U provides a lawn curling yarn winding machine. In this patent, a reciprocating rod assembly is placed above the winding drum. The reciprocating rod assembly is heavy, and as the diameter of the winding drum increases, the angle of the reciprocating rod assembly also changes. That is, initially, the weight of the reciprocating rod assembly presses on the winding drum, but as the diameter increases, the pressure exerted on the winding drum by the weight of the reciprocating rod assembly decreases, causing the pressure on the curling yarn to change, thus affecting the winding quality of the curling yarn. Therefore, in order to ensure the forming quality of the curling yarn, this new constant tension curling yarn winding machine was designed. Utility Model Content

[0003] The purpose of this invention is to provide a novel constant tension filament winding machine. The reciprocating pressure bar assembly is always in close contact with the winding roller, which improves the winding quality. Furthermore, by placing the reciprocating pressure bar assembly below the winding roller, the influence of the gravity of the reciprocating pressure bar assembly on the winding roller is reduced, keeping the filament in a constant tension state and further improving the winding quality.

[0004] This utility model provides the following technical solution: a novel constant tension curved yarn winding machine, comprising a frame, characterized in that: a guide wheel, a traction roller, and a traction inclined roller are connected to the upper part of the frame; a reciprocating pressure rod assembly and a winding roller are rotatably connected to the middle part of the frame; a tension rod is connected to the lower part of the frame; the curved yarn is sequentially wound around the guide wheel, the traction roller, the traction inclined roller, the tension rod, the reciprocating pressure rod assembly, and the winding roller; the reciprocating pressure rod assembly is located on the lower side of the winding roller; a guide rail is fixed on the surface of the frame; the reciprocating pressure rod assembly swings along the guide rail; a brake assembly is fixed on the side of the reciprocating pressure rod assembly, causing the reciprocating pressure rod assembly to adhere to the winding roller.

[0005] Furthermore, the reciprocating pressure bar assembly includes a rotating housing rotatably connected by a mounting rod, a pressure plate rotatably connected inside the rotating housing, a first connecting seat fixed to the side of the rotating housing, a connecting rod hinged to the first connecting seat, a second connecting seat fixed to the side of the pressure plate, and the other end of the connecting rod hinged to the second connecting seat. The oscillation of the rotating housing causes the connecting rod to drive the pressure plate to rotate, keeping the pressure plate always in contact with the take-up roller.

[0006] Furthermore, a reciprocating rod is rotatably connected to the side of the pressure plate via a bracket. A sliding sleeve is threaded onto the reciprocating rod. The curved wire passes through the sliding sleeve and winds around the take-up roller. The reciprocating rod is attached to the take-up roller, and the curved wire is reciprocated and evenly wound around the take-up roller through the reciprocating rod.

[0007] Furthermore, the brake assembly includes a rod inserted into the rotating housing, and a brake handle is hinged to the end of the rod. The brake handle swings to control the forward and backward movement of the rod, pressing the rod against the guide rail and fixing the rotating housing. The brake assembly increases the friction between the rotating housing and the guide rail, allowing the reciprocating rod assembly to fit against the side of the take-up roller.

[0008] Furthermore, a stop block is fixed on the insertion rod, and a spring is sleeved on the insertion rod. The spring is located between the stop block and the rotating housing, and the insertion rod is reset by the spring.

[0009] Furthermore, a mounting base is fixed on the lower part of the frame, and a rotating component is rotatably connected inside the mounting base. A swing rod is connected to the rotating component, and the end of the swing rod is connected to a tension rod. The swing rod drives the tension rod to fluctuate up and down, adjusting the tension of the filament and keeping the filament in a constant tension state, thereby improving the winding quality.

[0010] Furthermore, a limit rod is fixed on the side of the mounting base, and the swing rod swings within the limit rod.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) The reciprocating pressure bar assembly is always in close contact with the take-up roller, which improves the take-up quality. Furthermore, by placing the reciprocating pressure bar assembly below the take-up roller, the influence of the gravity of the reciprocating pressure bar assembly on the take-up roller is reduced, which keeps the filament in a constant tension state and further improves the take-up quality. (2) By winding the filament around the tension bar, the tension bar swings up and down with the change in the diameter of the take-up roller, which further ensures the constant tension of the filament and improves the take-up quality of the filament.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1 and 2This utility model provides a technical solution: a novel constant tension curved wire winding machine, including a frame 8. A guide wheel 2, a traction roller 1, and a traction inclined roller 3 are connected to the upper part of the frame 8. The guide wheel 2 is connected to the frame 8 via a shaft and bearings. A motor 11 is also fixed to the back of the frame 8. The output end of the motor 11 is connected to the traction roller 1, driving the traction roller 1 to rotate. The traction inclined roller 3 is connected to the frame 8 via bearings. The traction inclined roller 3 and the traction roller 1 are connected via a synchronous pulley and a synchronous belt. The frame 8 is also rotatably connected to a reciprocating pressure bar assembly 7 and a take-up roller 6. The take-up roller 6 is also bearing-connected to the frame 8. The take-up speed of the take-up roller 6 is controlled by another motor 11. A control button panel 5 is installed on the frame 8, which is used to adjust the rotation speed of the motor 11. A tension rod 4 is connected to the lower part of the frame 8. The curved wire is wound sequentially on the guide wheel 2, traction roller 1, traction skew roller 3, tension rod 4, reciprocating pressure bar assembly 7 and take-up roller 6. The reciprocating pressure bar assembly 7 is located below the take-up roller 6, reducing the impact of its gravity on the filaments on the take-up roller 6. A guide rail 77 is fixed to the surface of the frame 8, and the reciprocating pressure bar assembly 7 swings along the guide rail 77. A brake assembly is fixed to the side of the reciprocating pressure bar assembly 7, enhancing the friction between the reciprocating pressure bar assembly 7 and the guide rail 77, causing the reciprocating pressure bar assembly 7 to adhere to the take-up roller 6. As the take-up roller 6 winds up, the filaments on the take-up roller 6... The diameter of the bobbin gradually increases, providing support to the reciprocating pressure bar assembly 7, causing the reciprocating pressure bar assembly 7 to swing to the left. The curved wire is clamped between the reciprocating pressure bar assembly 7 and the take-up roller 6. The clamping of the curved wire ensures the winding quality of the curved wire. At the same time, the change in the winding diameter of the curved wire will increase the tension force received by the curved wire, causing the tension bar to swing up and down under the action of the curved wire. This further adjusts the tension force on the curved wire on the tension bar 4, so that the curved wire receives a constant tension, thus improving the winding quality of the curved wire.

[0015] The reciprocating pressure bar assembly 7 includes a rotating housing 72 rotatably connected by a mounting rod 71. The rotating housing 72 rotates around the mounting rod 71. A pressure plate 76 is rotatably connected inside the rotating housing 72. One end of the pressure plate 76 is rotatably connected inside the rotating housing 72 by a pin. A first connecting seat 73 is fixed to the side of the rotating housing 72. A second connecting seat 75 is connected to the side of the pressure plate 76. A connecting rod 74 is hinged to the first connecting seat 73. The other end of the connecting rod 74 is hinged to the second connecting seat 75. The swinging of the rotating housing 72 causes the connecting rod 74 to tilt to one side, which in turn pushes the pressure plate 76 to tilt to one side as well. Because the second connecting seat 75 is fixed to the bottom surface of the pressure plate 76, the pressure plate 76 causes the reciprocating rod 78 to tilt, further ensuring that the curved wire is always located between the pressure plate 76 and the take-up roller 6.

[0016] A reciprocating rod 78 is rotatably connected to the side of the pressure plate 76 via a bracket. The bracket is fixed to the pressure plate 76, and the reciprocating rod 78 is rotatably connected to the bracket via a pin. A sliding sleeve is threaded onto the reciprocating rod 78. The curved wire passes through the sliding sleeve and winds around the take-up roller 6. The reciprocating rod 78 is in contact with the take-up roller 6. The rotation of the reciprocating rod 78 adjusts the movement of the sliding sleeve. The reciprocating motion of the sliding sleeve drives the curved wire to reciprocate on the take-up roller 6, so that the curved wire is evenly distributed on the take-up roller 6.

[0017] The brake assembly includes a rod 79 inserted into the rotating housing 72. A brake handle 710 is hinged to the end of the rod 79. The brake handle 710 swings to control the forward and backward movement of the rod 79, pressing the rod 79 against the guide rail 77 to fix the rotating housing 72.

[0018] A stop 711 is fixed on the insertion rod 79, and a spring 712 is sleeved on the insertion rod 79. The spring 712 is located between the stop 711 and the rotating housing 72. After the brake handle 710 is reset, the spring force causes the insertion rod 79 to reset, moving the insertion rod 79 away from the guide rail 77, which facilitates the adjustment of the position of the pressure plate 76.

[0019] A mounting base 41 is fixed on the lower part of the frame 8. A rotating component 42 is rotatably connected inside the mounting base 41. A swing rod 43 is connected to the rotating component 42. The end of the swing rod 43 is connected to the tension rod 4. The rotation of the rotating component 42 drives the swing rod 43 to rotate, causing the tension rod 4 to swing up and down, fluctuating with the change in diameter on the take-up roller 6.

[0020] A limiting rod 44 is fixed on the side of the mounting base 41. The limiting rod 44 is a U-shaped rod. The swing rod 43 swings within the limiting rod 44, limiting the fluctuation angle of the swing rod 43.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
