Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, it relates to an automatic selvage tension adjustment device. Background Technology

[0002] Tension is a physics concept, mainly used to describe a mechanical effect produced when an object deforms under the action of external force, especially when it undergoes tensile deformation.

[0003] As products continue to pursue differentiation and diversification, many existing looms (including air-jet, water-jet, and rapier looms) have opted to install a selvage folding device, commonly known as a smooth selvage machine. When using this device, most selvages can still be woven normally when the weft density is not high. However, when weaving high-density fabrics, the increased selvage density (1cm-1.5cm of selvage is twice the density of other parts) causes the weft opening to deviate significantly outward, resulting in a weft opening slippage phenomenon. At this time, the folded selvage edge will not be able to hook in, resulting in fuzzy fabric, which seriously affects product quality. Utility Model Content

[0004] The purpose of this invention is to provide an automatic selvage tension adjustment device to solve the above-mentioned problems.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic selvage tension adjustment device, comprising: a housing, on which a base is fixedly installed; a tension roller, rotatably connected to the base, the side of the tension roller being provided with a plurality of protrusions for inserting into the selvage; a support mechanism, installed on the base, the support mechanism being used to ensure that the selvage and the protrusions are always in contact; and a power mechanism, installed on the housing, the power mechanism being used to drive the tension roller to rotate.

[0006] The tension roller is driven by a power mechanism to increase the gripping force on the selvage. Combined with a support mechanism, this ensures that the selvage and the tension roller are always in contact. Therefore, the tension of the selvage can be actively adjusted to ensure that the selvage does not deviate too much during the weaving process. In other words, the tension of the selvage is actively adjusted through electromechanical integration, which in turn ensures the smooth operation of the selvage folding device. This allows the selvage folding device to smoothly hook the yarn in, thus keeping the surface of the woven fabric smooth and improving product quality.

[0007] Preferably, the support mechanism includes a roller, and an elastic component for driving the roller to lift the fabric edge upward is installed between the roller and the base.

[0008] By incorporating an elastic component, the roller can be made to move upwards under the weight of the fabric edge, thus ensuring that the fabric edge and the tassels remain in contact during use.

[0009] Preferably, the elastic component includes a bracket mounted on the base, a linkage plate rotatably connected to the bracket, a roller mounted on one end of the linkage plate, and a tension spring installed between the other end of the linkage plate and the bracket.

[0010] The force of the tension spring is used to ensure that the end of the linkage plate away from the tension spring has an upward tendency, which in turn drives the idler roller to have an upward tendency, thus supporting the edge of the fabric.

[0011] Preferably, a fixed plate is fixedly installed on the bracket, and a slot for one end of the tension spring to be inserted is provided on one side of the fixed plate, and a pin for the other end of the tension spring to be hooked is threaded onto the linkage plate.

[0012] By setting a separate mounting plate, that is, by adopting a separate structure between the mounting plate and the bracket, they can be manufactured separately, reducing production costs. Furthermore, due to the cooperation between the slots and pins, the two ends of the tension spring can be quickly assembled onto the slots and pins, making assembly simpler and more convenient.

[0013] Preferably, the base has a positioning groove on its side, a first screw hole in the positioning groove, the bracket is slidably connected to the positioning groove, and the bracket has an elongated hole that mates with the first screw hole.

[0014] By setting the bracket to slide within the positioning groove, the mating position of the elongated hole and the first screw hole can be adjusted appropriately, which in turn facilitates the adjustment of the tension roller to a certain position to improve its adaptability.

[0015] Preferably, the power mechanism includes a geared motor and a driven pulley coaxially arranged with the tensioning roller. The output shaft of the geared motor is equipped with a driving pulley, and a belt is arranged between the driving pulley and the driven pulley.

[0016] By using a belt drive to move the tension roller, the transmission is smoother and the performance is improved.

[0017] Preferably, a limiting protrusion is fixedly connected to the side of the output shaft of the geared motor, and a limiting groove is provided on the inner wall of the drive pulley to slide with the limiting protrusion.

[0018] By setting mutually cooperating limit protrusions and limit grooves, the assembly process can be completed simply by inserting the drive pulley into the output shaft of the geared motor, making the assembly process simpler and more convenient.

[0019] Preferably, the output shaft end face of the geared motor is provided with a second screw hole, and a side baffle is fixedly installed in the second screw hole by screws.

[0020] By setting a side baffle, the drive pulley can be blocked, preventing it from coming off the output shaft of the geared motor and improving its performance.

[0021] In summary, this utility model has the following beneficial effects:

[0022] This invention increases the gripping force on the fabric selvage by driving the movement of the spikes on the tension roller through a power mechanism, and combines this with a support mechanism to ensure that the fabric selvage and the spikes are always in contact. Therefore, it can actively adjust the tension of the selvage to ensure that the selvage does not deviate too much during the weaving process. That is, it actively adjusts the tension of the selvage through electromechanical combination, thereby ensuring the smooth operation of the selvage folding device, so that the selvage folding device can smoothly hook the yarn in, achieving the goal of keeping the surface of the woven fabric smooth and improving product quality.

[0029] 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.

[0030] like Figures 1-3As shown, an automatic selvage tension adjustment device includes a housing 10, a base 3 fixedly mounted on the housing 10, a tension roller 8 rotatably connected to the base 3, a plurality of protrusions 81 for inserting into the selvage on the side of the tension roller 8, a support mechanism mounted on the base 3 to ensure that the selvage and the protrusions 81 are always in contact, and a power mechanism mounted on the housing 10 to drive the tension roller 8 to rotate.

[0031] By using a power mechanism to drive the movement of the spikes 81 on the tension roller 8 to increase the gripping force on the selvage, and combined with a support mechanism to ensure that the selvage and the spikes 81 are always in contact, the tension of the selvage can be actively adjusted to ensure that the selvage does not deviate too much during the weaving process. That is, the tension of the selvage is actively adjusted through electromechanical combination, which in turn ensures the smooth operation of the selvage folding device, so that the selvage folding device can smoothly hook the yarn in, thereby achieving the goal of keeping the surface of the woven fabric smooth and improving product quality.

[0032] It is worth mentioning that, such as Figure 2 and Figure 4 As shown, the side of the base 3 is provided with a shaft hole 33, and a bearing is installed in the shaft hole 33. The inner ring of the bearing is fixedly connected to the central shaft of the tension roller 8 to achieve smooth rotation.

[0033] Furthermore, such as Figure 3 As shown, the support mechanism includes a roller 9. An elastic component is installed between the roller 9 and the base 3 to drive the roller 9 to support the fabric edge upward. Under the gravity of the fabric edge, the elastic component can make the roller 9 move upward, thereby ensuring that the fabric edge and the tack 81 are always in contact during use.

[0034] It is understandable that, such as Figure 3 As shown, the idler roller 9 and the tension roller 8 are located on both sides of the fabric edge.

[0035] Furthermore, such as Figure 3 As shown, the elastic component includes a bracket 4 mounted on the base 3, a linkage plate 7 rotatably connected to the bracket 4, a roller 9 mounted on one end of the linkage plate 7, and a tension spring 6 installed between the other end of the linkage plate 7 and the bracket 4.

[0036] The force of the tension spring 6 is used to ensure that the end of the linkage plate 7 away from the tension spring 6 has an upward movement tendency, which in turn drives the idler roller 9 to have an upward movement tendency, thus playing the role of supporting the edge of the fabric.

[0037] It is understandable that, such as Figure 3 As shown, the linkage plate 7 is rotatably engaged with the bracket 4 via the pin 72. The linkage plate 7 can be divided into a horizontal part and an inclined part. The hinge point of the linkage plate 7 is located at the junction of the horizontal part and the inclined part, that is, the pin 72 is located at the junction of the horizontal part and the inclined part. The idler roller 9 is fixedly installed at the end of the inclined part away from the horizontal part.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, a fixed plate 5 is fixedly installed on the bracket 4. A slot 51 is provided on one side of the fixed plate 5 for one end of the tension spring 6 to be inserted. A pin 71 is threadedly connected to the linkage plate 7 for the other end of the tension spring 6 to be hooked.

[0039] The fixed plate 5 and the bracket 4 adopt a separate structure, which can be manufactured separately, reducing production costs. Furthermore, due to the cooperation between the slot 51 and the pin 71, the two ends of the tension spring 6 can be quickly assembled onto the slot 51 and the pin 71, making assembly simpler and more convenient.

[0040] It is understandable that, such as Figure 3 As shown, pin 71 is located at the end of the horizontal section away from the oblique section.

[0041] Furthermore, such as Figure 2 and Figure 4 As shown, the base 3 has a positioning groove 31 on its side, and a first screw hole 32 is provided in the positioning groove 31. The bracket 4 is slidably connected in the positioning groove 31, and an elongated hole 41 is provided on the bracket 4 to cooperate with the first screw hole 32.

[0042] Since the bracket 4 can slide in the positioning groove 31, the mating position of the elongated hole 41 and the first screw hole 32 can be adjusted appropriately, which in turn facilitates the adjustment of the tension roller 8 to a certain position to improve its adaptability.

[0043] It is worth mentioning that, such as Figure 2 and Figure 4 As shown, there are two of each of the first screw hole 32 and the oblong hole 41, and they are set in a one-to-one correspondence.

[0044] Furthermore, such as Figure 1 and Figure 2 As shown, the power mechanism includes a geared motor 1 and a driven pulley 23 coaxially arranged with the tension roller 8. The output shaft of the geared motor 1 is equipped with a driving pulley 21. A belt 22 is arranged between the driving pulley 21 and the driven pulley 23. The tension roller 8 is driven by belt transmission, which makes the transmission smoother and improves the performance.

[0045] Furthermore, such as Figure 1 and Figure 5 As shown, a limiting protrusion 211 is fixedly connected to the side of the output shaft of the geared motor 1. The inner wall of the drive pulley 21 is provided with a limiting groove 11 that slides with the limiting protrusion 211. The limiting protrusion 211 and the limiting groove 11 cooperate with each other so that during assembly, it is only necessary to insert the drive pulley 21 onto the output shaft of the geared motor 1 to complete the assembly process, making the assembly process simpler and more convenient.

[0046] Furthermore, such as Figure 1 and Figure 5 As shown, the output shaft end face of the geared motor 1 is provided with a second screw hole 12. A side baffle is fixedly installed in the second screw hole 12 by screws, which can block the drive pulley 21 and prevent it from coming off the output shaft of the geared motor 1, thereby improving the performance.

[0047] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
