Description

Technical Field

[0001] This utility model relates to the field of manufacturing machinery, and more specifically, it relates to a wire take-up device and a wire drawing machine. Background Technology

[0002] The wire drawing machine achieves continuous processing of plastic filaments through the linear synergy of four core components. The extrusion unit plasticizes plastic granules (such as PP and PE) or melts them, forming a preform through a spinneret. The preform filament is rapidly cooled by a water bath or air-cooling system to prevent deformation and improve crystallinity. Then, a traction and stretching device cuts the preform into filaments, achieving a 5-10 times stretch through multi-stage roller speed differences. A hot drying oven softens the filament, causing the molecular chains to align and significantly improving tensile strength. Finally, a winding device winds the filaments. The winding device includes a winding drum and a guiding mechanism. The winding drum drives the core drum to rotate, causing the plastic filaments to wind around it. The reciprocating motion of the guiding mechanism ensures uniform winding of the filaments. Existing technologies use reciprocating screws for guiding, which require keyways to be machined on the screw surface, resulting in high processing difficulty, high cost, easy wear, and high maintenance costs. Therefore, there is an urgent need for a simple and low-cost winding device. Utility Model Content

[0018] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly or indirectly attached to that other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component. This "connection" is not limited to a fixed connection or a movable connection; the specific connection method should be determined based on the specific technical problem to be solved.

[0020] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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 limitations on this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Example 1: This example provides a take-up device that uses a reciprocating push rod 22 as the core component of the guide mechanism 2, resulting in a simple structure and low cost. The take-up device includes a cabinet 1, a drive mechanism, a winding mechanism 3, and a guide mechanism 2. The cabinet 1 is hollow inside for mounting the drive mechanism, the winding mechanism 3, and the guide mechanism 2. The right side of the cabinet 1 is a mounting plate 11, which has shaft mounting holes and push rod mounting holes.

[0023] The winding mechanism 3 includes a take-up roller; the take-up roller is coaxially connected to the winding shaft 32; the winding shaft 32 passes through a rotating shaft mounting hole and is rotatably connected to the cabinet 1, meaning the take-up roller rotates under the drive of the winding shaft 32. The take-up roller is used to house the core tube 0. After the core tube 0 is housed, it rotates under the drive of the take-up roller and winds the yarn. The yarn guiding mechanism 2 includes a reciprocating push rod 22, which has a guide hole; the guide hole is used to guide the yarn; the reciprocating push rod 22 passes through the push rod mounting hole and is slidably connected to the cabinet 1; meaning the reciprocating push rod 22 can extend and retract from the cabinet 1. The reciprocating push rod 22 is arranged parallel to the take-up roller. The drive mechanism simultaneously drives the take-up roller to rotate and the reciprocating push rod 22 to reciprocate.

[0024] Traditional wire guide mechanisms rely on reciprocating lead screws with keyways on their surfaces, which require precision machining and are prone to wear. This device uses a smooth reciprocating push rod 22, eliminating the need for keyway machining and significantly reducing manufacturing difficulty and material costs. The drive mechanism simultaneously controls rotational and reciprocating motions, reducing the need for independent motors or transmission components and further simplifying the structure.

[0025] Example 2: This example provides a winding device based on the above examples, giving the specific structure of the reciprocating mechanism and the specific implementation of the driving mechanism, achieving the technical effect of one machine serving multiple purposes.

[0026] The drive mechanism includes a drive motor 12; a first spatial transmission gear 13 and a first parallel shaft transmission gear 15 are provided on the output shaft 14 of the drive motor 12; a second spatial transmission gear 31 is provided on the winding shaft 32; the first spatial transmission gear 13 and the second spatial transmission gear 31 mesh. Preferably, a bearing is provided in the shaft mounting hole; the winding shaft 32 is connected to the cabinet 1 through the bearing.

[0027] The reciprocating push rod 22 is provided with a sliding groove 221, and the axis of the sliding groove 221 is perpendicular to the axis of the reciprocating push rod 22; the cabinet 1 is provided with a gear mounting bracket 16, and a second parallel shaft transmission gear is mounted on the gear mounting bracket 16; the first parallel shaft transmission gear 15 meshes with the second parallel shaft transmission gear.

[0028] The second parallel shaft transmission gear is provided with a sliding handle 211; the sliding handle 211 cooperates with the sliding groove 221.

[0029] Optionally, the first spatial transmission gear 13 and the second spatial transmission gear 31 are bevel gears; the first parallel shaft transmission gear 15 and the second parallel shaft transmission gear are either spur gears or helical gears. By changing the transmission ratio of the first spatial transmission gear 13 and the second spatial transmission gear 31, the rotational speed of the take-up roller can be changed. Similarly, by adjusting the position of the gear mounting bracket 16 and the transmission ratio of the first parallel shaft transmission gear 15 to the second parallel shaft transmission gear, the reciprocating speed of the reciprocating push rod 22 can be adjusted. Adjusting the position of the sliding handle 211 on the second parallel shaft transmission gear can change the stroke of the reciprocating push rod 22.

[0030] Preferably, a bearing or a small wheel is provided on the sliding handle 211 so that the sliding handle 211 can move smoothly within the sliding groove 221.

[0031] Example 3: This example provides a take-up device based on the above examples, and provides a take-up roller structure, which solves the problem of increased equipment cost caused by relying on pneumatic expansion to fix the core cylinder in the prior art.

[0032] The take-up roller includes a roller section 33 and a baffle 34; a slider hole is provided on the roller section; an extrusion hole is provided on the baffle 34; a tension block 42 is provided inside the slider hole; a first inclined surface is provided at the bottom of the tension block 42; an extrusion pin 41 is provided inside the roller section 33, and the extrusion pin 41 has a second inclined surface that cooperates with the first inclined surface; the extrusion hole is used to install an extrusion assembly 43; the extrusion assembly 43 is connected to the extrusion pin 41 through a springback component; the springback component is used to reset the extrusion assembly 43 and the extrusion pin 41.

[0033] Preferably, a retraction spring is provided between the tensioning block 42 and the roller portion 33. As the second inclined plane moves away from the first inclined plane, the retraction spring retracts the tensioning block 42 back into the slider hole. Optionally, a force-bearing platform is provided at the bottom of the tensioning block 42, and the roller portion 33 has a cavity to accommodate the force-bearing platform. A retraction spring is provided within the cavity, with its two ends abutting against the roller portion 33 and the force-bearing platform, respectively. In use, the retraction spring is in a compressed state.

[0034] Preferably, the roller portion 33 is provided with at least three slider holes and tensioning blocks 42 corresponding to the number of slider holes; the pressing pin 41 is provided with a second inclined surface corresponding to the number of tensioning blocks 42; the at least three slider holes are arranged in an array along the circumference of the roller portion 33. The at least three slider holes form a group; at least two groups of slider holes are provided on the axis of the roller portion 33.

[0035] Before the core cylinder 0 is fitted into the roller section 33, the extrusion assembly 43 is in an unpressurized state. At this time, the extrusion pin 41 is kept in its reset state under the action of the spring-loaded component (such as a spring), the tension block 42 retracts into the slider hole, and the outer diameter of the roller is smaller than the inner diameter of the core cylinder 0, which facilitates the insertion of the core cylinder 0.

[0036] The operator pushes the extrusion assembly 43, causing it to apply pressure inward through the extrusion hole. The extrusion assembly 43 pushes the extrusion pin 41 to move, and the second inclined surface of the extrusion pin 41 slides relative to the first inclined surface at the bottom of the tensioning block 42. The inclined surface design converts the axial movement of the extrusion pin 41 into the radial expansion movement of the tensioning block 42.

[0037] When disassembling the core cylinder 0, the pressure on the extrusion assembly 43 is released. The springback component automatically pushes the extrusion pin 41 to reset, and the tension block 42 retracts into the slider hole along with the inclined plane. The outer diameter of the roller decreases, and the core cylinder 0 can be easily removed.

[0038] Traditional pneumatic expansion structures require air pumps, pipelines, and control valves. This design achieves the same function through a purely mechanical structure, reducing costs and enhancing reliability.

[0039] Example 4: This example provides a take-up device based on the above examples, and provides a self-locking mechanism to achieve the purpose of self-locking after the core tube is installed.

[0040] The baffle 34 includes a front baffle 34134 and a baffle 34 cover; the front baffle 34134 and the baffle 34 cover are combined to form an inner cavity; the baffle 34 cover is connected to the winding shaft 32; the front baffle 34134 is connected to the roller; the springback component includes a linkage disc;

[0041] The linkage plate is set in the inner cavity; the extrusion pin 41 is fixedly connected to the linkage plate; the extrusion assembly 43 includes an extrusion block 431, which passes through the extrusion hole and is connected to the linkage plate; a return spring 44 is provided on the linkage plate; one end of the return spring 44 is connected to the linkage plate, and the other end is connected to the front baffle 34134.

[0042] The extrusion assembly 43 also includes a self-locking tongue 432; the extrusion block 431 is provided with a self-locking groove 433; one end of the self-locking tongue 432 is connected to the front baffle 34134 through a torsion spring 435, and the other end cooperates with the self-locking groove 433; the extrusion block 431 is also provided with an unlocking protrusion 434; the unlocking protrusion 434 is located between the self-locking groove 433 and the front baffle 34134.

[0043] Preferably, the front baffle 34134 is provided with at least three extrusion components 43, and the at least three extrusion components 43 are arranged in a row around the axis of the core cylinder O.

[0044] Preferably, it includes at least three return springs 44, and the at least three return springs 44 are arranged in a row around the axis of the core cylinder O.

[0045] Preferably, the tensioning block 42 is made of a material such as rubber that has good elasticity and a high coefficient of friction.

[0046] When the core cylinder 0 is not installed, the pressing block 431 is in the retracted position under the action of the return spring 44, and the self-locking tongue 432 disengages from the self-locking groove 433 under the action of the torsion spring 435, allowing the core cylinder to be inserted into the take-up cylinder without obstruction. Pushing the pressing block 431 inward causes the linkage disc to move axially, and the pressing pin 41, along with the linkage disc, pushes the tensioning block 42 (through a bevel engagement) to expand radially, causing the tensioning block 42 to press against the inner wall of the core cylinder 0, fixing the core cylinder 0 under the action of friction. When the pressing block 431 moves to the set position, the self-locking tongue 432 automatically engages in the self-locking groove 433 of the pressing block 431 under the action of the torsion spring 435, preventing the pressing block 431 from rebounding and ensuring that the tensioning block 42 continuously presses against the core cylinder 0, preventing it from disengaging from the self-locking groove 433 during high-speed rotation. After the winding is complete, push the core cylinder 0 inward. The unlocking protrusion 434 will lift the self-locking tongue 432 and disengage it from the self-locking groove 433. The return spring 44 will pull the linkage plate to reset. The pressing pin 41 will disengage from the tensioning block 42. Under the action of the recovery spring, the tensioning block 42 will retract radially, and the core cylinder 0 can be easily removed.

[0047] This self-locking mechanism solves the pain points of traditional pneumatic expansion and fixing, which are "high cost, slow response and easy failure", through an innovative combination of mechanical locking and elastic reset.

[0048] Example 5: This example provides a wire drawing machine, which includes an extrusion device, a cooling device, a traction and stretching device, and the wire take-up device in the previous examples.

[0049] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
