Abstract
Description
Technical Field
[0001] This utility model relates to the field of rewinding machine technology, and in particular to a rewinding machine with stable winding. Background Technology
[0002] Rewinding machines are primarily used to transfer finished or semi-finished products from one package to another for inspection, meter counting, or repackaging. The working principle of a rewinding machine is based on the rewinding and winding of wire or tubing by a take-up mechanism. When the wire or tubing enters the take-up mechanism via the support platform, the take-up arm winds it onto the drum. Simultaneously, the transmission system drives the drum to rotate, causing the wire or tubing to wind onto the drum with a certain tension. During the rewinding process, the tightness of the wire or tubing can be controlled by adjusting the winding tension to meet different needs.
[0003] Existing rewinding machines cannot adjust the tension during wire winding, which can easily lead to insufficient winding tension and cause the filaments on the take-up reel to become loose. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rewinding machine with stable winding.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rewinding machine with stable winding includes a rewinding machine body. A fixed frame is provided on one side of the rewinding machine body. A screw drive assembly is provided between the fixed frames, and a tensioning assembly is provided between the fixed frames through the screw drive assembly. The tensioning assembly includes a fixed seat. Support seats are symmetrically installed on both sides of the top of the fixed seat. A movable roller assembly is inserted into the middle between the two support seats. A first guide roller assembly and a second guide roller assembly are symmetrically arranged above the two sides between the two support seats.
[0007] Furthermore, in a preferred configuration, the movable roller assembly includes a fixed shaft, a first guide roller is sleeved on the outer wall of the fixed shaft, and T-shaped fixing blocks are symmetrically installed on both sides of the fixed shaft. An extension rod is installed at one end of each T-shaped fixing block, and a limiting sleeve is sleeved on the outer wall of the extension rod.
[0008] In addition, a preferred structure is that extension blocks are symmetrically installed on both sides of the outer wall of the extension rod and outside the support base, and a sliding groove is provided through the extension block inside the limiting sleeve.
[0009] Furthermore, in a preferred configuration, the support base has equidistant locking grooves at the T-shaped fixing block, and an auxiliary groove is provided through one side of the locking groove in the support base, with the cross-sectional area of the auxiliary groove being the same as that of the T-shaped fixing block.
[0010] In addition, a preferred structure is that the support base has a movable sliding groove at the extension rod and a limit slot at the limit sleeve.
[0011] In addition, a preferred structure is that T-shaped guide blocks are installed at the top and bottom of the auxiliary chute, and through holes are opened at the top and bottom of the T-shaped fixing blocks at the T-shaped guide blocks.
[0012] The beneficial effects of this utility model are as follows:
[0013] In this invention, the screw drive assembly, in conjunction with the tensioning assembly, allows the tensioning assembly to reciprocate smoothly through precise control of the screw drive assembly. During the reciprocating horizontal linear motion of the tensioning assembly, the tension of the wire is stably controlled, ensuring that the wire maintains a constant tension state during winding and reducing the occurrence of slack or excessive tension in the wire during winding.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Reference Figure 1-3A rewinding machine with stable winding includes a rewinding machine body 1. A fixed frame 2 is provided on one side of the rewinding machine body 1. A screw drive assembly 3 is provided between the fixed frames 2, and a tensioning assembly 4 is provided between the fixed frames 2 through the screw drive assembly 3. The tensioning assembly 4 includes a fixed seat 41. Support seats are symmetrically installed on both sides of the top of the fixed seat 41. A movable roller assembly 45 is inserted into the middle between the two support seats. A first guide roller assembly 42 and a second guide roller assembly 43 are symmetrically arranged above the two sides between the two support seats. The tensioning assembly 4 is driven by the screw drive assembly 3 to perform horizontal reciprocating linear motion. The specific structure, connection method and working principle of the screw drive assembly 3 and the rewinding machine body 1 are all existing technologies that have been disclosed in the market and are not the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them.
[0020] The first guide roller assembly 42 and the second guide roller assembly 43 both include a limiting shaft, and the outer wall of the limiting shaft is fitted with a second guide roller.
[0021] Furthermore, the movable roller assembly 45 includes a fixed shaft, a first guide roller is sleeved on the outer wall of the fixed shaft, and T-shaped fixing blocks 451 are symmetrically installed on both sides of the fixed shaft. An extension rod 452 is installed at one end of the T-shaped fixing block 451, and a limiting sleeve 454 is sleeved on the outer wall of the extension rod 452.
[0022] Furthermore, extension blocks 453 are symmetrically installed on both sides of the outer wall of the extension rod 452 and outside the support base, and a sliding groove is provided through the limit sleeve 454 at the extension block 453.
[0023] Meanwhile, the support base has a locking groove at equal intervals at the T-shaped fixing block 451, and an auxiliary groove is provided through the support base on one side of the locking groove. The cross-sectional area of the auxiliary groove is the same as that of the T-shaped fixing block 451.
[0024] Meanwhile, a movable sliding groove is provided inside the support base at the extension rod 452, and a limit slot is provided inside the support base at the limit sleeve 454.
[0025] Furthermore, T-shaped guide blocks 44 are installed at the top and bottom of the auxiliary chute, and through holes are opened at the top and bottom of the T-shaped fixing block 451 at the T-shaped guide block 44.
[0026] In this embodiment, by using the lead screw drive assembly 3 in conjunction with the tensioning assembly 4, the tensioning assembly 4 can smoothly reciprocate under the precise control of the lead screw drive assembly 2. During the reciprocating horizontal linear motion of the tensioning assembly 4, the tension of the wire is stably controlled, ensuring that the wire maintains a constant tension state during the winding process and reducing the occurrence of loosening or excessive tension of the wire during the winding process.
[0027] The wound wire is passed sequentially through the top of the first guide roller assembly 42, the bottom of the movable roller assembly 45, and the top of the second guide roller assembly 43, and then wound onto the outer wall of the take-up roller of the rewinding machine body 1.
[0028] When tension adjustment is required, the groove of the limiting sleeve 454 is aligned with its extension block 453 and the limiting sleeve 454 is removed. Then, the extension rod 452 is slid along the movable groove 452 to be located in the auxiliary groove. As needed, the T-shaped fixing block 451 is slid to be located in the corresponding locking groove. Then, the groove of the limiting sleeve 454 is aligned with its extension block 453 and locked. Then, the limiting sleeve 454 is rotated until its groove is no longer aligned with its extension block 453. The whole process is convenient, and the limiting sleeve 454 limits the movable roller assembly 45 to ensure its stability.
[0029] In this invention, the screw drive assembly 3, in conjunction with the tensioning assembly 4, allows the tensioning assembly 4 to reciprocate smoothly under the precise control of the screw drive assembly 2. During the reciprocating horizontal linear motion of the tensioning assembly 4, the tension of the wire is stably controlled, ensuring that the wire maintains a constant tension state during the winding process and reducing the occurrence of loosening or excessive tension in the wire during the winding process.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
