Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a spandex filament support device. Background Technology

[0002] In the textile industry, spandex filament is one of the main raw materials for producing elastic yarn, and its usage is increasing significantly. All machinery requiring spandex filament must be equipped with or select suitable spandex filament support devices. Existing spandex filament support devices generally include a support assembly and a spandex filament bobbin support core roller mounted on the support assembly. For example, in a spandex filament support device disclosed in Chinese Patent Publication No. CN205023610U, a rotatable base is mounted on the mounting plate via a connecting shaft. A handle is provided at the upper end of the base, and a rotatable shaft is provided on the base. The shaft includes a body, a spring, and a tensioning body. Two tensioning bodies are symmetrically arranged on the body, and a spring is provided between the two tensioning bodies. The spring is located within the body.

[0003] However, when using a shaft to support the spandex bobbin, the lack of a device to restrict the left and right sides of the spandex bobbin causes it to deviate as it rotates on the shaft. This can cause the spandex bobbin to fall off the shaft, thus affecting the use of the spandex bobbin. Utility Model Content

[0004] To address the problem mentioned in the background art, where the spandex bobbin loses its position and falls off the shaft due to the lack of a device to restrict the left and right sides of the bobbin, this invention provides the following technical solution:

[0005] A spandex filament support device includes a support shaft for mounting spandex filament bobbins, a clamping device for clamping and fixing the spandex filament bobbins on the shaft body, and a limiting device movably connected to the clamping device for assisting the clamping device in restricting the spandex filament bobbins on the support shaft.

[0006] The clamping device includes a drive assembly mounted on a support shaft for left and right movement, and a reset assembly for controlling the movement of the drive assembly is provided inside the support shaft.

[0007] The limiting device includes a limiting component for folding disposed within the drive assembly, and the limiting component is provided with rollers for assisting the spandex filament bobbin to rotate on the support shaft.

[0008] Furthermore, the support shaft has two arc grooves for the drive assembly to move left and right, and storage slots for storing the restraining assembly are provided at both ends of the support shaft.

[0009] Furthermore, the reset assembly includes a circular rod disposed within an arc groove for moving the reset assembly left and right, and a spring for controlling the left and right movement of the drive assembly is fitted onto the rod.

[0010] Furthermore, the drive assembly includes a movable ring fitted on a round rod for left and right movement. The movable ring has a hinge groove for allowing the limiting assembly to rotate, and a pin for locking the limiting assembly.

[0011] Furthermore, the limiting component includes a hinge plate disposed within the hinge groove for hinged engagement, wherein the end of the hinge plate away from the moving ring has a placement groove for the roller to roll.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By setting up a clamping device and a limiting device, when it is necessary to install and use the spandex filament bobbin, firstly, the two moving rings are controlled to move away from each other, which compresses the spring on the round rod. Then, the spandex filament bobbin is fitted onto the support shaft. By erecting the hinge plate around the hinge groove, and then inserting the pin through the moving ring and the hinge plate, the erected limiting component can be fixed. At the same time, the compressed spring, under the elastic action, can make the two moving rings move closer to each other, which can make the rollers on the two hinge plates move closer to the spandex filament bobbin on the support shaft, thereby limiting the spandex filament bobbin and preventing it from falling off the support shaft.

[0026] Please see Figures 1-5 This utility model provides a spandex filament support device.

[0027] The device includes a support shaft 100 for mounting spandex filament bobbins. The support shaft 100 has two clamping devices 200 for clamping and fixing the spandex filament bobbins. The two clamping devices 200 are symmetrically distributed on the support shaft 100. A limiting device 300 is movably connected to the clamping device 200 to assist the clamping device 200 in restricting the spandex filament bobbins on the support shaft 100.

[0028] The support shaft 100 has two arc grooves 101 on its shaft body for the drive assembly 210 to move left and right. The two arc grooves 101 are symmetrically distributed on the shaft body of the support shaft 100 to facilitate the movement of the two drive assemblies 210 within the two arc grooves 101. The support shaft 100 has two storage slots 102 on its left and right ends for storing the limiting assembly 310. The two storage slots 102 are symmetrically distributed on the left and right ends of the support shaft 100.

[0029] The clamping device 200 includes a drive assembly 210 mounted on the support shaft 100 for left and right movement, and the drive assembly 210 can move left and right within two arc grooves 101; a reset assembly 220 is provided in the support shaft 100 for controlling the movement of the drive assembly 210.

[0030] The reset assembly 220 includes two round rods 221 disposed in the arc groove 101 for moving the reset assembly 220 left and right. The two round rods 221 are symmetrically distributed in the arc groove 101. A spring 222 for controlling the left and right movement of the drive assembly 210 is fitted on the rod body of the round rod 221. The spring 222 is located on the right side of the drive assembly 210 so that the elastic action of the compressed spring 222 can be used to restrict the spandex bobbin on the support shaft 100 to prevent the spandex bobbin from falling off the support shaft 100.

[0031] The drive assembly 210 includes a movable ring 211 mounted on a round rod 221 for left and right movement, and the movable ring 211 can move within the arc groove 101; the movable ring 211 has a hinge groove 212 for the restriction assembly 310 to rotate, and there are two hinge grooves 212, which are symmetrically distributed vertically on the ring body of the movable ring 211; the movable ring 211 has a pin 213 for locking the restriction assembly 310, so that the pin 213 can pass through the movable ring 211 and the restriction assembly 310 to fix the vertically erected restriction assembly 310, thereby restricting the spandex bobbin mounted on the support shaft 100 to prevent the spandex bobbin from falling off the support shaft 100.

[0032] The limiting device 300 includes a limiting component 310 disposed within the drive assembly 210 for folding, and a roller 320 disposed within the limiting component 310 for assisting the spandex filament bobbin to rotate on the support shaft 100.

[0033] The limiting component 310 includes a hinge plate 311 disposed within the hinge groove 212 for hinged connection, and a pin 213 can pass through the moving ring 211 and the plate body of the hinge plate 311 to fix the vertically erected limiting component 310. The end of the hinge plate 311 away from the moving ring 211 has a placement groove 312 for the roller 320 to roll. Therefore, when it is necessary to install and use the spandex filament bobbin, firstly, the two moving rings 211 are controlled to move away from each other, which compresses the spring 222 on the round rod 221, and then the spandex filament bobbin is fitted onto it. On the support shaft 100, by erecting the hinge plate 311 around the hinge groove 212, and then inserting the pin 213 through the moving ring 211 and the plate body of the hinge plate 311, the erected limiting component 310 can be fixed. At the same time, the spring 222 in the compressed state can make the two moving rings 211 move closer to each other under the elastic action, so that the rollers 320 on the two hinge plates 311 can move closer to the spandex bobbin on the support shaft 100, thereby limiting the spandex bobbin and preventing the spandex bobbin from falling off the support shaft 100.

[0034] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
