Description

Technical Field

[0001] This utility model relates to the field of fabric processing, specifically to a positioning fixture for irregularly shaped tubular fabrics that is easy to adjust. Background Technology

[0002] Irregular tubular fabrics are textiles with a cylindrical structure. They are characterized by forming a continuous loop during the weaving process, similar to a tube or cylinder, such as cuffs or protective sleeves in clothing. To facilitate subsequent dyeing, printing, sewing, and finishing processes, they need to be positioned.

[0003] During the positioning process, due to the elasticity of the fabric and the different tubular diameters of different specifications of fabric, it is inconvenient to adjust the support range. Furthermore, during processing, the fabric is prone to slipping out and detaching, making it inconvenient to automatically press and fix the bottom end of the fabric. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable positioning fixture for irregularly shaped tubular fabrics to solve the technical problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An easily adjustable positioning fixture for irregularly shaped tubular fabric includes a chassis. An adjustment mechanism is installed inside the chassis, and a fixing mechanism is installed on the top of the chassis. The adjustment mechanism includes three slides movably mounted on the top of the chassis. A positioning plate is fixedly mounted on the top of each slide. Three screws are movably mounted inside the chassis, and three guide rods are fixedly mounted. A worm gear is movably mounted near the bottom of the chassis. The top of the worm gear's shaft and the inner ends of the three screws are each equipped with bevel teeth. A worm is movably mounted through the interior of the chassis, and a knob is fixedly mounted on the outer end of the worm.

[0007] Preferably, the positioning plate is arranged in an arc shape, and the three slides and the three positioning plates are arranged in a circumferential configuration.

[0008] Preferably, the slide is movably connected to the outside of the screw and the guide rod, and the slide and the screw are connected by a thread.

[0009] Preferably, the bevel teeth at the top of the worm gear are meshed with the bevel teeth at the inner end of the screw, and the worm and the worm gear are meshed together.

[0010] Preferably, the fixing mechanism includes three guide seats, which are respectively fixedly installed on the outer side of three slides. A pressure plate is movably installed inside the guide seat. Several positioning blocks are provided on the inner wall of the pressure plate. A pull rod is installed on the outer side of the pressure plate and through the outer end of the guide seat. A spring is sleeved on the outside of the pull rod. A pull plate is fixedly installed on the outer end of the pull rod.

[0011] Preferably, the inner walls on both sides of the guide seat are provided with guide rail grooves, and the bottom end of the pressure plate is located inside the guide seat and is slidably disposed through the guide rail grooves.

[0012] Preferably, the pull rod and the pressure plate are fixedly installed together, and the pull rod slides through the outer end of the guide seat.

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

[0014] 1) This positioning fixture, through the setting of an adjustment mechanism, the screw drives the slide to slide, thereby changing the distance between the three positioning plates, which facilitates the adjustment and positioning of tubular fabrics of different specifications. Through the threaded connection of the screw and the meshing of the worm gear, the slide is automatically fixed after adjustment and sliding.

[0015] 2) This positioning fixture, through the setting of a fixing mechanism, pulls the pressure plate to slide outward, and the pressure plate slides inward under the action of the spring. Through the positioning block, the friction between the pressure plate and the fabric is increased, which can press and fix the bottom end of the fabric, making it convenient for fixing and taking the fabric out.

[0020] 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.

[0021] Example 1

[0022] Combination Figures 1-3 An adjustable irregularly shaped tubular fabric positioning fixture includes a chassis 1, an adjustment mechanism 2 installed inside the chassis 1, and a fixing mechanism 3 installed on the top of the chassis 1.

[0023] See Figure 2 Furthermore, the adjustment mechanism 2 includes three slides 4, which are movably mounted on the top of the chassis 1. Each slide 4 has a positioning plate 5 fixedly mounted on its top. Inside the chassis 1, three screws 6 are movably mounted and three guide rods 7 are fixedly mounted. Inside the chassis 1, a worm gear 8 is movably mounted near the bottom. The top of the shaft of the worm gear 8 and the inner ends of the three screws 6 are both equipped with bevel teeth 9. A worm 10 is movably mounted through the interior of the chassis 1, and a knob 11 is fixedly mounted on the outer end of the worm 10.

[0024] The positioning plate 5 is arranged in an arc shape, and the three slides 4 and the three positioning plates 5 are arranged in a ring. The fabric is sleeved on the outside of the three positioning plates 5 and is opened and positioned by the positioning plates 5.

[0025] The slide 4 is movably connected to the outside of the screw 6 and the guide rod 7. The slide 4 and the screw 6 are connected by a thread. The screw 6 drives the slide 4 and the positioning plate 5 to slide, thereby adjusting and positioning fabrics of different specifications.

[0026] The bevel teeth 9 at the top of the worm gear 8 are meshed with the bevel teeth 9 at the inner end of the screw 6. The worm 10 is meshed with the worm gear 8. The worm 10 drives the worm gear 8 to rotate, so that the three screws 6 rotate simultaneously for quick adjustment.

[0027] Specifically, rotating the worm 10 causes the three screws 6 to rotate simultaneously through the meshing of the worm wheel 8 and the meshing of the bevel teeth 9. The slide 4 slides through the threads of the screws 6, changing the distance between the three positioning plates 5, thereby changing the diameter of the three positioning plates 5 surrounding each other, so as to adjust and position tubular fabrics of different specifications.

[0028] Example 2

[0029] See Figure 3Furthermore, based on Embodiment 1, the fixing mechanism 3 includes three guide seats 12, which are respectively fixedly installed on the outside of the three slide seats 4. A pressure plate 13 is movably installed inside the guide seat 12. Several positioning blocks 14 are provided on the inner wall of the pressure plate 13. A pull rod 15 is installed on the outside of the pressure plate 13 and through the outer end of the guide seat 12. A spring 16 is sleeved on the outside of the pull rod 15. A pull plate 17 is fixedly installed on the outer end of the pull rod 15.

[0030] Guide rail grooves are provided on both inner walls of the guide seat 12. The bottom end of the pressure plate 13 is located inside the guide seat 12 and is slidably set through the guide rail groove. The pressure plate 13 slides inward to press the bottom end of the fabric tightly. The positioning block 14 increases the friction between the pressure plate and the fabric.

[0031] The pull rod 15 is fixedly installed with the pressure plate 13. The pull rod 15 passes through the outer end of the guide seat 12 and is slidably installed. The pressure plate 13 is slidably pulled by the pull rod 15, which facilitates the quick fixing and loading of the fabric.

[0032] Specifically, pulling the lever 15 outward causes the spring 16 to contract, the pressure plate 13 to slide outward and disengage from the positioning plate 5, the fabric is sleeved on the outside of the positioning plate 5, and the pressure plate 13 slides inward under the action of the spring 16 to press the bottom end of the fabric tightly, and the positioning block 14 increases the friction to fix the bottom end of the fabric.

[0033] In actual operation, the irregularly shaped tubular fabric is sleeved on the outside of the three positioning plates 5. The three positioning plates 5 support and position the fabric for subsequent processing.

[0034] When adjusting, turning the knob 11 drives the worm 10 to rotate. Through the meshing of the worm 10 with the worm wheel 8 and the meshing between the bevel teeth 9, the worm 10 drives the worm wheel 8 to rotate. The worm wheel 8 drives the three screws 6 to rotate simultaneously. The screws 6 drive the slide block 4 to slide through the thread, thereby changing the distance between the three positioning plates 5, and thus changing the diameter of the three positioning plates 5 surrounding each other, so as to adjust and position tubular fabrics of different specifications.

[0035] When fixing, pull rod 15 is pulled outward by pull plate 17, so that pressure plate 13 slides outward and disengages from positioning plate 5. When the fabric is sleeved on the outside of positioning plate 5, pull rod 15 is pulled outward, and pressure plate 13 slides inward under the action of spring 16 to press the bottom end of the fabric. The positioning block 14 increases the friction force, thereby fixing the bottom end of the fabric, so as to fix the fabric and put it away.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
