Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a yarn tube holder that facilitates yarn tube replacement. Background Technology

[0002] A yarn bobbin holder is a component used to support yarn bobbins, which are formed by winding batches of yarn onto rollers. In the textile technology field, the yarn on the yarn bobbin holder needs to be pulled towards subsequent processing equipment to complete processes such as cutting and dyeing of the yarn.

[0003] For example, Chinese patent document CN220766110U discloses a textile roller for textiles, relating to the field of textile roller technology. This invention includes a base, with a support frame welded to its upper surface. The support frame has grooves and support slots on its upper surface. This invention uses a cover plate, with identical support frames installed at both ends of the take-up shaft to fix it. The fixing slot, locking slot, fastening slot, and support slot are threaded. The cover plate can be opened or closed by rotating a shaft and a rotating block in a rotatable engagement.

[0004] In the above technical solution, in order to avoid the gauze from contacting the ground during the traction process, the yarn bobbin needs to be set at a certain height. However, the yarn bobbin is quite heavy after being wound up. Therefore, when replacing the yarn bobbin, the worker needs to lift the yarn bobbin to a certain height before installing it on the yarn bobbin frame, which makes it more laborious and inconvenient to replace the yarn bobbin. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a yarn tube holder that facilitates yarn tube replacement and provides convenience for yarn tube replacement.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a yarn tube frame for easy yarn tube replacement, comprising a base, on which two frames that can move toward each other or away from each other are provided, the frames being used to support the ends of the yarn tube, and a lifting platform being provided above the base, the lifting platform lifting the yarn tube to the target position of the frames to facilitate yarn tube replacement.

[0007] The present invention is further configured such that: a support frame and a cylinder are provided on the base; the support frame is fixed to the base; symmetrically arranged slide rails are provided on the support frame; a slider is coupled on the slide rail; the slider and the slide rail form a sliding fit; the lifting platform is connected to the surface of the slider; and the cylinder is used to drive the slider to slide along the slide rail to realize the lifting of the lifting platform.

[0008] The present invention is further configured such that: a horizontally arranged connecting beam is provided on the support frame; a connecting seat is fixed to the output end of the cylinder; a horizontally extending connecting rod is provided on the connecting seat; a drive gear is fitted around the outer periphery of the connecting rod; and a drive chain is provided between the lifting platform and the connecting beam, the drive chain meshing with the drive gear.

[0009] The present invention is further configured such that: a rotatable bidirectional lead screw is provided on the base, and two side frames are respectively fitted on both sides of the bidirectional lead screw and respectively form a threaded engagement; a motor is provided on one side of the bidirectional lead screw, and the motor is used to drive the bidirectional lead screw to rotate.

[0010] The present invention is further configured such that: a support plate is provided on the inner side of the frame, and a rotatable support wheel is provided on the support plate, the support wheel contacting the end of the yarn bobbin to support the yarn bobbin.

[0011] The present invention is further configured such that: the end of the yarn bobbin is provided with an annular positioning groove adapted to the support wheel, the support wheel is coupled to the annular positioning groove, and a rolling fit can be formed between the two.

[0012] The present invention is further configured such that: a support seat is provided on the lifting platform, and a support groove is provided on the support seat to match the curvature of the yarn tube end.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Because of the adjustable lifting platform, when changing yarn bobbins, workers only need to place the bobbins on the lifting platform, and the platform will lift the bobbins to the target position on the machine frame to complete the replacement. In this way, the only work required to replace the bobbins is to lift them from the ground to the lifting platform, making it easier and more convenient for workers. Therefore, it effectively solves the technical problem in the existing technology where workers need to lift the bobbins too high, making the replacement process laborious.

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for 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 the invention.

[0020] like Figures 1 to 3 As shown, this utility model discloses a yarn tube frame that facilitates yarn tube replacement, including a base 1. The base 1 is provided with two frames 2 that can move towards each other or away from each other. The frames 2 are used to support the ends of the yarn tube 100 to realize the mounting of the yarn tube 100. A lifting platform 3 is provided above the base 1. The lifting platform 3 lifts the yarn tube 100 to the target position of the frames 2 by lifting. In this way, when the worker lifts the yarn tube 100, he only needs to overcome the work generated by the height of the ground from the lifting platform 3. After the yarn tube 100 is placed on the lifting platform 3, the lifting platform 3 will then lift the yarn tube 100. This makes it easier for the worker to replace the yarn tube 100. In addition, the two frames 2 are designed to be movable. When replacing the yarn tube 100, the two frames 2 can be moved away from each other to increase the distance between them, so as to increase the activity space and avoid interference with the lifting of the yarn tube 100.

[0021] In this embodiment, the lifting platform 3 has the following structure for lifting: a support frame 4 and a cylinder 5 are provided on the base 1. The support frame 4 is fixed to the base 1 and has symmetrically arranged slide rails 6. A slider 7 is coupled to the slide rails 6, and the slider 7 and the slide rails 6 form a sliding fit. The lifting platform 3 is connected to the surface of the slider 7. A horizontally arranged connecting beam 41 is provided on the support frame 4. A drive chain 11 is provided between the lifting platform 3 and the connecting beam 41. The two ends of the drive chain 11 are fixed to the connecting beam 41 and the lifting platform 3, respectively. A connecting seat 8 is fixed to the output end of the cylinder 5. A horizontally extending connecting rod 9 is provided on the connecting seat 8. A drive gear 10 is fitted around the outer periphery of the connecting rod 9. The drive gear 10 can rotate around the axis of the connecting rod 9. The drive chain 11 rotates and meshes with the drive gear 10. When the cylinder 5 drives the lifting platform 3 to rise and fall, the drive gear 10 follows the extension and retraction of the output end of the cylinder 5 to rise and fall. The friction generated by the meshing of the drive gear 10 and the drive chain 11 causes the drive gear 10 to rotate, so that there is relative movement between the drive chain 11 and the drive gear 10, thereby driving the lifting platform 3 to rise and fall. In addition, the design of the drive chain 11 and the drive gear 10 can form a movable pulley, which reduces the driving force requirement of the cylinder 5 while increasing the lifting stroke. Furthermore, the sliding action formed between the slider 7 and the slide rail 6 can guide the lifting platform 3 to rise and fall, ensuring the stability of the lifting platform 3 during the lifting process.

[0022] Additionally, it should be noted that the drive chain 11 shown in the attached diagram is for illustrative purposes only. In practice, the drive chain 11 can adopt a conventional structure.

[0023] In this embodiment, the structure for the two side frames 2 to move towards each other or away from each other is as follows: a rotatable bidirectional lead screw 12 is provided on the base 1, and the two ends of the bidirectional lead screw 12 are rotatably connected to the base 1 through bearings. The two side frames 2 are respectively fitted on both sides of the bidirectional lead screw 12 and respectively form a threaded engagement. A motor 13 is provided on one side of the bidirectional lead screw 12. The motor 13 is used to drive the bidirectional lead screw 12 to rotate. When the motor 13 drives the bidirectional lead screw 12 to rotate, under the limiting action of the guide rods 17 on both sides of the bidirectional lead screw 12, the two side frames 2 can move towards each other or away from each other along the direction of the bidirectional lead screw 12.

[0024] In this embodiment, the structure for supporting the end of the yarn bobbin 100 by the frame 2 is as follows: a support plate 14 is provided on the inner side of the frame 2, and the support plate 14 is fixed to the support plate 14 by pins. A rotatable support wheel 15 is provided on the support plate 14, and the pin fixed on the support plate 14 serves as the rotation axis of the support wheel 15. The support wheel 15 contacts the end of the yarn bobbin 100, and the support wheels 15 are symmetrically arranged to support the end of the yarn bobbin 100. In addition, an annular positioning groove 100a adapted to the support wheel 15 is provided at the end of the yarn bobbin 100. The support wheel 15 is coupled to the annular positioning groove 100a to limit the axial movement of the yarn bobbin 100 and improve the stability of the support for the yarn bobbin 100. When the subsequent traction equipment, such as the take-up roller, tractions the yarn on the yarn bobbin 100, the support wheel 15 and the annular positioning groove 100a can form a rolling fit to reduce the friction force on the yarn bobbin 100 when it rotates.

[0025] In this embodiment, a support base 16 is provided on the lifting platform 3, and a support groove 161 is provided on the support base 16 to match the curvature of the end of the yarn tube 100. In this way, when the yarn tube 100 is placed on the lifting platform 3, the support groove 161 limits the end of the yarn tube 100, which can prevent the yarn tube 100 from falling off the lifting platform 3 during the lifting process.

[0026] The implementation process for this solution is as follows:

[0027] When the yarn bobbin 100 needs to be installed for replacement, the motor 13 drives the bidirectional lead screw 12 to move the two side frames 2 in opposite directions, increasing the distance between them. At this point, the worker can move the yarn bobbin 100 onto the lifting platform 3 and position its end in the support groove 161 for limiting. Then, the output end of the cylinder 5 extends to raise the lifting platform 3 until the yarn bobbin 100 is above the frame 2. The opposing movement of the two side frames 2 previously allows the support wheels 15 to be misaligned with the end of the yarn bobbin 100, preventing interference with the lifting path of the yarn bobbin 100. Interference occurs, and then the motor 13 reverses, causing the two frames 2 to move towards each other until the support wheel 15 is moved to a position opposite to the annular positioning groove 100a on the end of the yarn tube 100. Then, by resetting the output end of the cylinder 5, the lifting platform 3 is lowered until the end of the yarn tube 100 contacts the support wheel 15, so that the yarn tube 100 can be mounted on the frame 2, completing the replacement of the yarn tube 100. In this way, the only work required to replace the yarn tube 100 is to lift the yarn tube 100 from the ground to the lifting platform 3, making it easier for workers to replace the yarn tube 100.

[0028] 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.
