[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Example 1

[0027] Reference Figure 1-3 A positioning device for a rapier loom includes a frame 1, an mounting base 2 mounted on the inner side of the frame 1, a fabric roll support 3 mounted on the top of the mounting base 2, and a mating mechanism between the mounting base 2 and the fabric roll support 3. The mating mechanism is used for quick connection between the mounting base 2 and the fabric roll support 3. The mating mechanism includes a sleeve 4, a positioning groove 5, and a locking component. The four corners of the top of the mounting base 2 are fixed with sleeves 4, and the top of each sleeve 4 is provided with a positioning groove 5. The positioning groove 5 is slidably connected to the four feet at the bottom of the fabric roll support 3. A locking component is mounted between the sleeve 4 and the feet.

[0028] The locking assembly includes a built-in groove 6, a drag plate 7, a lock head 8, a connecting spring 9, a shuttle rod 10, and an anti-disengagement groove 11. The built-in groove 6 is located on the inner side of the support sleeve 4, offset from the positioning groove 5. The built-in groove 6 communicates with the positioning groove 5. The drag plate 7 is slidably connected to the inner side of the built-in groove 6. The shuttle rod 10 is fixed to one side of the drag plate 7 and is slidably connected to the support sleeve 4. The lock head 8 is fixed to the other side of the drag plate 7 and is slidably connected to the built-in groove 6. A connecting spring 9 is sleeved on the outer side of the shuttle rod 10. A spring 9 is connected to a drag plate 7 at one end, and another end of the spring 9 is fixed to the inner side of the built-in groove 6 at the other end. A non-disengagement groove 11 corresponding to the position of the lock head 8 is provided on one side of the support leg. The non-disengagement groove 11 is slidably connected to the lock head 8. An inclined surface is provided at one end of the lock head 8. When the support leg is inserted along the inner side of the positioning groove 5 and contacts the inclined surface, the inclined surface can push the lock head 8 to retract towards the inner side of the built-in groove 6, which facilitates the quick connection between the support leg and the support sleeve 4.

[0029] Example 2

[0030] Further optimizations to Example 1, specifically, such as... Figure 1 , 4As shown in Figure 5, an adjustment mechanism is installed between the mounting base 2 and the frame 1. The adjustment mechanism is used to adjust the height of the fabric roll support 3. The adjustment mechanism includes a first hydraulic rod 12, a force-applying rod 13, a sliding sleeve 14, a first transmission rod 15, a second transmission rod 16, and a transmission assembly. An inverted U-shaped frame is slidably connected to the top of the frame 1. The first hydraulic rod 12 is fixed to the top of the inner side of the inverted U-shaped frame. The output end of the first hydraulic rod 12 passes through the inverted U-shaped frame and is fixed to the force-applying rod 13. Both ends of the force-applying rod 13 are rotatably connected to the sliding sleeve 14. The inner side of the sliding sleeve 14 is slidably connected to the first transmission rod 15. One end of the first transmission rod 15 is rotatably connected to the inverted U-shaped frame. Two second transmission rods 16 are rotatably connected to one end of the bottom of the mounting base 2. A transmission assembly is installed between the mounting base 2 and the inverted U-shaped frame. When the first hydraulic rod 12 is activated, its output end pushes the force-applying rod 13 upward. Since the force-applying rod 13 is rotatably connected to the sliding sleeve 14 and the sliding sleeve 14 is slidably connected to the first transmission rod 15, the sliding sleeve 14 can drive the first transmission rod 15 to rotate. Since the first transmission rod 15 and the second transmission rod 16 are rotatably connected through the central rod 17, and the rollers 18 are in close contact with the mounting base 2 and the inverted U-shaped frame, the first transmission rod 15 and the second transmission rod 16 can rotate in opposite directions, thereby changing the height of the mounting base 2 and adjusting the height of the fabric roll support 3.

[0031] The transmission assembly includes a central rod 17, rollers 18, and a guide limit frame 19. A central rod 17 is rotatably connected to the middle of the first transmission rod 15 and the second transmission rod 16. A roller 18 is rotatably connected to the end of the first transmission rod 15 away from the inverted U-shaped frame. A roller 18 is also rotatably connected to the end of the second transmission rod 16 away from the mounting base 2. The rollers 18 are in close contact with the mounting base 2 and the inverted U-shaped frame. Guide limit frames 19 are fixed to the bottom of the mounting base 2 and the top of the inverted U-shaped frame. The rollers 18 are in close contact with the inner side of the guide limit frames 19. The guide limit frames 19 provide guidance and limit for the movement of the rollers 18.

[0032] Both ends of the frame 1 are fixed with second hydraulic rods 20. The output ends of the second hydraulic rods 20 are fixed to the inverted U-shaped frame. The second hydraulic rods 20 facilitate the adjustment of the lateral displacement of the inverted U-shaped frame. When the two second hydraulic rods 20 are activated, their output ends retract and extend respectively.

[0033] In summary:

[0034] This utility model addresses the technical problem of the fixed connection between the fabric roll support and the connecting seat in existing technologies, making it difficult to quickly remove the fabric roll support when it needs to be disassembled, repaired, or replaced. The present invention employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:

[0035] During use, when it is necessary to separate the fabric roller support 3 from the mounting base 2, pull the shuttle rod 10 so that the shuttle rod 10 drives the drag plate 7 to move along the inner side of the built-in groove 6. At the same time, the drag plate 7 compresses the connecting spring 9 to retract, thereby causing the locking head 8 to retract into the built-in groove 6 and separate from the anti-detachment groove 11. At this time, the locking head 8 releases the vertical limit on the support foot of the fabric roller support 3. Then, pull the fabric roller support 3 upward so that the support foot separates from the positioning groove 5. This can achieve quick separation between the mounting base 2 and the fabric roller support 3, which is convenient for subsequent maintenance or replacement of the fabric roller support 3.

[0036] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0037] 1. Through the structural design of the matching mechanism, this utility model makes it easy to quickly connect the fabric roll support 3 and the mounting base 2. At the same time, when it is necessary to repair or replace the fabric roll support 3 with a different specification of fabric roll support 3 in the later stage, the fabric roll support 3 can be quickly separated from the mounting base 2, which makes it easier for users to speed up the disassembly and assembly.

[0038] 2. Through the structural design of the adjustment mechanism and the second hydraulic rod 20, this utility model enables the device to adjust the height and lateral position of the fabric roll support 3, which is beneficial for the rapid positioning of the fabric roll support 3 and solves the problem of difficulty in manual adjustment in the traditional way.
