Description

Technical Field

[0001] This utility model relates to the technical field of yarn take-up equipment, and in particular to a take-up structure for a winding machine. Background Technology

[0002] A winding machine can be used to take up linear or strip products such as textile yarns and nylon ropes into spools. During take-up, the mandrel is placed over the take-up roller of the winding machine. The take-up roller then drives the mandrel to rotate, causing the linear or strip product to wind onto the mandrel. As the axial reciprocating speed of the take-up roller is adjusted, the spacing of the linear or strip product winding on the spool varies, thus obtaining spools with different textures. In existing technology, the yarn is guided by guide wheels and finally wound onto the mandrel by pressure rollers. The pressure rollers only compress the winding portion of the yarn on the spool and cannot roll other parts of the spool. The resulting spools have insufficient take-up tightness and it is difficult to obtain spools with complex textures, resulting in a monotonous spool texture. Utility Model Content

[0003] The purpose of this invention is to propose a winding structure for a winding machine, which features tight winding that prevents the yarn from fraying and facilitates the production of spools with diverse textures.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A winding structure for a winding machine includes a winding roller, a pressing mechanism, and a swing arm. The pressing mechanism is parallel to the winding roller, and the length of the pressing mechanism is equal to or greater than the length of the winding roller.

[0006] One end of the swing arm is connected to the body of the winding machine, and the other end of the swing arm is connected to the pressing mechanism. The swing arm causes the pressing mechanism to press against the surface of the spool on the take-up roller.

[0007] Furthermore, the pressing mechanism includes a roller frame and a pressure roller mounted on the roller frame, the pressure roller being parallel to the take-up roller, and the length of the pressure roller being equal to or greater than the length of the take-up roller.

[0008] Furthermore, a telescopic drive mechanism is connected to the tail end of the take-up roller, and a mounting plate is fixed to the tail end of the take-up roller.

[0009] One end of the roller frame is slidably connected to the mounting plate, and the top of the roller frame is slidably connected to the swing arm.

[0010] Furthermore, the swing arm includes a main arm and a connecting arm. One end of the main arm is connected to the body of the winding machine, and the other end is rotatably connected to a connecting rod.

[0011] The connecting arm is rotatably connected to the end of the connecting rod, and the connecting arm is slidably engaged with the roller frame.

[0012] Furthermore, the main arm and the connecting arm are each provided with a number of guide rollers.

[0013] Furthermore, a vertical baffle is provided on the side of the connecting arm near the mounting plate, and the vertical baffle is provided with the guide roller.

[0014] Furthermore, a torque adjusting component is provided at the connection between the main arm and the body of the winding machine.

[0015] Furthermore, a telescopic cylinder is connected between the mounting plate and the body of the winding machine, and the telescopic cylinder extends and / or retracts as the take-up roller moves.

[0016] Furthermore, the take-up roller includes a roller shaft, an expansion sleeve, and a locking rod. The roller shaft has a positioning plate with an inclined platform at each end. The positioning plate at the outer end of the roller shaft is slidably engaged with the roller shaft. The locking rod passes through the positioning plate at the outer end of the roller shaft and is threadedly connected to the roller shaft.

[0017] The technical solution provided by this utility model can include the following beneficial effects:

[0018] In this technical solution, a pressing mechanism is used instead of the pressing wheel in the prior art, and the length of the pressing mechanism is equal to or greater than the length of the take-up roller. This allows the pressing mechanism to press the entire spool on the take-up roller, making the wire wound on the spool tight and less prone to unraveling. This enables the take-up structure to be used to obtain spools with more complex textures, which is beneficial for obtaining spools with diverse textures using a winding machine.

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Reference Figures 1-5 The present invention discloses a winding structure for a winding machine, comprising a winding roller 1, a pressing mechanism 2, and a swing arm 3. The pressing mechanism 2 is parallel to the winding roller 1, and the length of the pressing mechanism 2 is equal to or greater than the length of the winding roller 1.

[0027] One end of the swing arm 3 is connected to the body of the winding machine, and the other end of the swing arm 3 is connected to the pressing mechanism 2. The swing arm 3 causes the pressing mechanism 2 to press against the surface of the spool 6 on the take-up roller 1.

[0028] In this invention, a pressing mechanism 2 replaces the pressing wheel of the prior art, and the length of the pressing mechanism 2 is equal to or greater than the length of the take-up roller 1, so that the pressing mechanism 2 can press the entire spool 6 on the take-up roller 1, making the wire wound on the spool 6 tight and not easy to unravel, so that the take-up structure can be used to obtain spools 6 with more complex textures, which is beneficial to obtaining spools 6 with diverse textures using a winding machine.

[0029] The pressing element in the pressing mechanism 2 of this utility model can be a pressure roller 22 or an arc-shaped pressure plate. Preferably, the pressing mechanism 2 includes a roller frame 21 and a pressure roller 22 mounted on the roller frame 21. The pressure roller 22 is parallel to the take-up roller 1, and the length of the pressure roller 22 is equal to or greater than the length of the take-up roller 1. The pressure roller 22 ensures smooth take-up and more even pressure on the spool 6. Since the length of the take-up roller 1 corresponds to the length of the spool 6, typically the spool 6 is the same length as the take-up roller 1 or slightly longer than the take-up roller 1 to achieve better positioning of the spool 6. In this solution, by limiting the relative length of the pressure roller 22 and the take-up roller 1, the length of the pressure roller 22 is adapted to the length of the spool 6, achieving the effect of synchronously pressing the entire spool 6. Specifically, both ends of the pressure roller 22 are rotatably connected to the roller frame 21.

[0030] In order to ensure that the pressing mechanism 2 can press against the spool 6 throughout the winding process, the tail end of the winding roller 1 is further connected to a telescopic drive mechanism 5, and the tail end of the winding roller 1 is fixed with a mounting plate 11.

[0031] One end of the roller frame 21 is slidably connected to the mounting plate 11, and the top of the roller frame 21 is slidably connected to the swing arm 3.

[0032] Understandably, the tail end of the take-up roller 1 is connected to a rotary drive motor, which is driven by the telescopic drive mechanism 5 to move, thereby realizing the axial movement of the take-up roller 1. Specifically, the telescopic drive mechanism 5 can be a screw drive, that is, the motor drives the screw to rotate, and the screw drives the rotary drive motor to move through the threaded sleeve. At the same time, the rotary drive motor and the body of the winding machine are connected by a slider and slide rail to achieve smooth movement.

[0033] During the take-up process, the telescopic drive mechanism 5 drives the take-up roller 1 to reciprocate axially, while the swing arm 3 remains in place, allowing the yarn to completely cover the mandrel. When the telescopic drive mechanism 5 drives the take-up roller 1 to reciprocate axially, the mounting plate 11 moves with the take-up roller 1, which in turn drives the entire pressing mechanism 2 to move synchronously with the take-up roller 1. Based on the sliding connection between the top of the roller frame 21 and the swing arm 3, the swing arm 3 can continuously apply pressure to the roller frame 21. Moreover, as the take-up progresses, the thickness of the yarn on the mandrel increases. Based on the sliding fit between the roller frame 21, the mounting plate 11, and the swing arm 3, the pressure roller 22 can remain pressed tightly against the surface of the spool 6. For example, the sliding fit between the roller frame 21 and the mounting plate 11, and the sliding fit between the roller frame 21 and the swing arm 3 are both achieved through a slider rail.

[0034] In one embodiment of this utility model, the swing arm 3 includes a main arm 31 and a connecting arm 32. One end of the main arm 31 is connected to the body of the winding machine, and the other end is rotatably connected to a connecting rod. The connecting arm 32 is rotatably connected to the end of the connecting rod, and the connecting arm 32 is slidably engaged with the roller frame 21. By connecting the main arm 31 and the connecting arm 32 with a connecting rod, the angle between the main arm 31 and the connecting arm 32 can change. Therefore, when the pressing mechanism 2 moves as the diameter of the bobbin 6 increases, the angle between the main arm 31 and the connecting arm 32 changes, and the swing arm 3 can maintain pressure on the pressing mechanism 2. Specifically, the bottom end of the main arm 31 is connected to the body of the winding machine, the upper end of the main arm 31 is connected to the top end of the connecting rod, and the bottom end of the connecting rod is connected to the connecting arm 32.

[0035] Preferably, the main arm 31 and the connecting arm 32 are each provided with a plurality of guide rollers 34 for guiding the conveyor belt.

[0036] Furthermore, a vertical baffle 35 is provided on the side of the connecting arm 32 near the mounting plate 11, and the guide roller 34 is provided on the vertical baffle 35. The vertical baffle 35 is used to limit the movement of the wire strip and has the effect of preventing wire tangling.

[0037] Furthermore, a torque adjusting component 36 is provided at the connection between the main arm 31 and the body of the winding machine. The torque adjusting component 36 is used to adjust the torque applied to the swing arm 3, thereby adjusting the pressure of the pressing mechanism 2 on the bobbin 6. Specifically, the torque adjusting component 36 includes a rotating shaft, a torsion spring, and an adjusting cylinder. The rotating shaft is installed on the body of the winding machine. The swing arm 3, the torsion spring, and the adjusting cylinder are all sleeved on the rotating shaft. One end of the torsion spring is connected to the swing arm 3, and the other end is connected to the adjusting cylinder. The adjusting cylinder is fixed to the rotating shaft by threads. The torque applied to the swing arm 3 by the torsion spring is changed by adjusting the angle of the adjusting cylinder.

[0038] Furthermore, a telescopic cylinder 12 is connected between the mounting plate 11 and the body of the winding machine. The telescopic cylinder 12 extends and / or retracts as the take-up roller 1 moves. The telescopic cylinder 12 is used to seal the gap between the take-up roller 1 and the body of the winding machine, preventing the yarn from entering the winding machine. Specifically, the telescopic cylinder 12 is mounted to the body of the winding machine via a connecting plate 4.

[0039] In one embodiment of this utility model, the take-up roller 1 includes a roller shaft, an expansion sleeve 14, and a locking rod 15. The two ends of the roller shaft are respectively provided with positioning disks 16 with inclined platforms. The positioning disk 16 at the outer end of the roller shaft is slidably engaged with the roller shaft. The locking rod 15 passes through the positioning disk 16 at the outer end of the roller shaft and is threadedly connected to the roller shaft.

[0040] When installing the mandrel of the spool 6 on the take-up roller 1, first, the mandrel is sleeved on the outside of the expansion sleeve 14. Then, the locking rod 15 is rotated so that it is screwed into the roller shaft, thereby pushing the positioning plate 16 into the expansion sleeve 14 until the outer wall of the expansion sleeve 14 abuts against the inner wall of the mandrel, thus positioning the mandrel. An operating knob is fixed to the end of the locking rod 15.
