Description

Technical Field

[0001] This utility model belongs to the field of textile technology, and in particular relates to a tensioning mechanism for the production of all-polyester nonwoven fabric. Background Technology

[0002] Polyester nonwoven fabric is a textile product with excellent water repellency, high temperature resistance, breathability, and loop properties. These advantages have led to its widespread application in various fields. During the production process, the tensioning mechanism needs to be controlled to adjust the tension of the polyester nonwoven fabric, effectively preventing it from becoming too loose and tangling, or too tight and breaking.

[0003] A search revealed a tensioning device for nonwoven fabric production disclosed in patent document CN221318604U, but it still has the following shortcomings in practical use:

[0004] 1. The tensioning device for nonwoven fabric production disclosed in the patent document with patent publication number CN221318604U controls the self-locking motor to adjust the tensioning component and adjust the tension of the nonwoven fabric. However, the tensioning component is only provided at one end of the tensioning roller, which can only limit the position of one end of the tensioning roller. When the reaction force of the nonwoven fabric on the tensioning roller is too large, it will cause one end of the tensioning roller to tilt, making the tension of the nonwoven fabric unstable and affecting the normal production of nonwoven fabric.

[0005] 2. The tensioning device for nonwoven fabric production disclosed in the patent document with patent publication number CN221318604U adjusts the tension of the nonwoven fabric by adjusting the position of the tensioning roller during use. The guide roller limits the direction of the nonwoven fabric, and the winding roller rotates to wind up the nonwoven fabric. However, during the winding process, it is not convenient to smooth out the wrinkles of the nonwoven fabric, which will reduce the production quality of the nonwoven fabric.

[0006] To address these issues, we provide a tensioning mechanism for the production of all-polyester nonwoven fabrics. Utility Model Content

[0007] The purpose of this utility model is to provide a tensioning mechanism for the production of all-polyester nonwoven fabric. By setting a tensioning component, both ends of the two tensioning shafts are supported by components, which makes the tensioning shafts more stably support the all-polyester nonwoven fabric. In addition, a smoothing component is set to perform a smoothing operation on both sides of the all-polyester nonwoven fabric, thereby improving the processing quality of the all-polyester nonwoven fabric. This solves the technical problem mentioned in the background art of the tensioning device for nonwoven fabric production disclosed in the patent document with patent publication number CN221318604U.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a tensioning mechanism for the production of all-polyester nonwoven fabric, comprising a base plate, a tensioning assembly on the base plate, and two mounting plates symmetrically connected to the base plate. Each mounting plate has a through groove on its side wall. A tensioning shaft is symmetrically arranged on the inner side of each mounting plate, and slide blocks rotatably connected to both ends of the tensioning shaft are slidably connected inside the through groove. A bidirectional lead screw is provided on the outer side of the mounting plate, and ball nuts are symmetrically arranged on its periphery. Sleeves on the periphery of the ball nuts are connected to the outer side of the slide blocks. A smoothing assembly is provided on the outer side of the tensioning shaft, and the smoothing assembly includes a smoothing shaft located on the outer side of the tensioning shaft.

[0010] The present invention is further configured such that the outer side of the substrate has a sleeved mounting plate, and the mounting plate has threaded holes arranged in a rectangular array.

[0011] The present invention is further configured such that a take-up shaft and an unwind shaft are symmetrically arranged on the inner side of the mounting plate, and both ends of the take-up shaft and the unwind shaft are rotatably connected to the side walls of the two mounting plates. The output end of the take-up motor connected to the outer side wall of one of the mounting plates is connected to the end of the take-up shaft.

[0012] The present invention is further configured such that a tensioning motor is connected to the outer wall of one of the mounting plates, and the output end of the tensioning motor is connected to the end of one of the bidirectional lead screws.

[0013] The present invention is further configured such that the bidirectional lead screw has a sleeved pulley on its peripheral side, and the two pulleys are together fitted with a transmission belt.

[0014] The present invention is further configured such that the side wall of the bracket connected to the side wall of the slide block has a groove, the side wall of the slider slidably connected inside the groove has a connecting seat, and the end of the screw threadedly connected to the other side wall of the bracket is rotatably connected to the connecting seat.

[0015] The present invention is further configured such that a connecting pin is provided on the other side wall of the slider, and the pin is rotatably connected to the end of the smoothing shaft.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a tensioning component, starts the tensioning motor, and rotates the bidirectional lead screw. When the two ball nuts on the same bidirectional lead screw move towards each other, the two tensioning shafts move towards each other, reducing the distance between the two tensioning shafts and thus reducing the tension force; conversely, the distance between the two tensioning shafts increases, thus increasing the tension force. At the same time, the positions of the two ends of the tensioning shaft are limited, increasing the bearing capacity of the tensioning shaft, making the tensioning shaft more stable in supporting the polyester nonwoven fabric, avoiding the polyester nonwoven fabric from becoming loose or overly tensile during the production process, which is beneficial to the normal production of polyester nonwoven fabric.

[0018] 2. By setting up a smoothing component, the tensioning shaft contacts one surface of the polyester nonwoven fabric while the winding shaft rotates to wind up the polyester nonwoven fabric, and the smoothing shaft contacts the other surface of the polyester nonwoven fabric. The cooperation between the tensioning shaft and the smoothing shaft can smooth the two surfaces of the polyester nonwoven fabric, which is beneficial to improving the production quality of the polyester nonwoven fabric.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 and Figure 2 This utility model is a tensioning mechanism for the production of all-polyester nonwoven fabric, including a base plate 1 and a mounting plate 101, and the position of the base plate 1 is locked by external bolts.

[0030] Specifically, a mounting plate 101 is sleeved on the outer side of the substrate 1, and the mounting plate 101 has threaded holes.

[0031] Furthermore, the mounting plate 101 has a U-shaped structure;

[0032] The operation process of this embodiment is as follows: place the mounting plate 101 in the placement position, tighten the bolt counterclockwise inside the threaded hole, and limit the substrate 1 to the mounting surface; conversely, remove the substrate 1 from the mounting surface.

[0033] Example 2

[0034] Please see Figure 1 and Figure 2 Based on the first specific embodiment, a tensioning assembly 2 is provided. The tensioning assembly 2 includes a winding motor 201, a tensioning motor 202, a bidirectional lead screw 202a, a tensioning shaft 203, a mounting plate 204, and a transmission belt 205. By controlling the tensioning motor 202, the distance between the two tensioning shafts 203 is adjusted to adjust the tension of the all-polyester nonwoven fabric. At the same time, the positions of the two ends of the tensioning shaft 203 are limited, which improves the stability of the tensioning shaft 203 and avoids excessive reaction force exerted by the all-polyester nonwoven fabric on the tensioning shaft 203, which would cause deformation of the tensioning shaft 203 and better stretch the all-polyester nonwoven fabric.

[0035] Specifically, the mounting plate 204 is vertically connected to the base plate 1, and a through slot 204a is formed on the side wall of the mounting plate 204. The winding motor 201 is connected to the outer side wall of the mounting plate 204, and the output end of the winding motor 201 has a winding shaft 201a connected in parallel. The winding shaft 201a is rotatably connected to the side wall of the mounting plate 204. The unwinding shaft 201b provided below the winding shaft 201a is rotatably connected to the side wall of the mounting plate 204. The tensioning motor 202 is connected to the side wall of the mounting plate 204, and the bidirectional lead screw 202a is rotatably arranged on the outer side of the mounting plate 204. On the wall, and on the peripheral side wall of the bidirectional lead screw 202a, there are symmetrically arranged ball nuts 202b, on the peripheral side wall of the ball nuts 202b, there is a sleeve 202c, on the side wall of the sleeve 202c, there is a connected slide 202d, the slide 202d is slidably connected inside the through groove 204a, and the inner side wall of the slide 202d is rotatably connected to the end of the tensioning shaft 203. The bidirectional lead screw 202a is connected to the output end of the tensioning motor 202, and a pulley 205a is sleeved on the peripheral side of the bidirectional lead screw 202a. The two pulleys 205a are together sleeved with a transmission belt 205.

[0036] Furthermore, the two mounting plates 204 are arranged symmetrically, the two bidirectional lead screws 202a are arranged symmetrically, and the two tensioning shafts 203 are arranged symmetrically.

[0037] The operation process of this embodiment is as follows: the free end of the all-polyester nonwoven fabric is wound around the upper side of a tensioning shaft 203, and then the free end of the all-polyester nonwoven fabric is wound around the lower side of another tensioning shaft 203. Then, the free end of the all-polyester nonwoven fabric is wound onto a take-up shaft 201a. The tensioning motor 202 is started, and the bidirectional lead screw 202a rotates. When the two ball nuts 202b on the bidirectional lead screw 202a move towards each other, the two tensioning shafts 203 move towards each other, reducing the tension. When the two ball nuts 202b on the bidirectional lead screw 202a move away from each other, the two tensioning shafts 203 move in opposite directions, increasing the tension. The take-up motor 201 is started, and the take-up shaft 201a rotates to wind up the all-polyester nonwoven fabric.

[0038] Example 3

[0039] Please see Figure 1 , Figure 3 and Figure 4 Based on specific embodiment one and specific embodiment two, a smoothing component 3 is provided. The smoothing component 3 includes a smoothing shaft 301, a bracket 302, a connecting seat 303, a screw 303a, a slider 304 and a shaft pin 304a. The smoothing shaft 301 is used to smooth the wrinkled surface of the all-polyester nonwoven fabric, which is beneficial to improving the production quality of the all-polyester nonwoven fabric.

[0040] Specifically, the smoothing shaft 301 has sliders 304 at both ends, and a shaft pin 304a connected to one side wall of the slider 304 is rotatably connected to the end of the smoothing shaft 301. The other side wall of the slider 304 has a connecting seat 303. The bracket 302 is connected to the side wall of the slide 202d, and the side wall of the bracket 302 has a groove 302a. The slider 304 is slidably connected inside the groove 302a. The other side wall of the bracket 302 has a threaded screw 303a, and the end of the screw 303a is rotatably connected to the side wall of the connecting seat 303.

[0041] Furthermore, the two smoothing shafts 301 are symmetrically arranged, and the bracket 302 has an L-shaped structure;

[0042] The operation process of this embodiment is as follows: the winding motor 201 is started, the winding shaft 201a rotates to wind up the polyester nonwoven fabric, and during the movement of the polyester nonwoven fabric, it comes into contact with the smoothing shaft 301 and the tensioning shaft 203 respectively, and the smoothing shaft 301 and the tensioning shaft 203 smooth different surfaces of the polyester nonwoven fabric; when the screw 303a is rotated clockwise, the slider 304 slides along the slide groove 302a, the connecting seat 303 moves away from the slide seat 202d, and the distance between the smoothing shaft 301 and the tensioning shaft 203 increases, which is suitable for polyester nonwoven fabrics with larger thickness; when the screw 303a is rotated counterclockwise, the smoothing shaft 301 moves closer to the tensioning shaft 203, which is suitable for polyester nonwoven fabrics with smaller thickness.
