[0029] The present invention will be described in detail below with reference to the drawings and embodiments.

[0030] Refer to Figures 1 to 4 As shown, a quick-change device for a flexible belt card holder provided in an embodiment of the present invention includes two synchronous belts 1, two connecting blocks 2, two transmission blocks 3, one head slider 4, one belt 5, one head clip 6, and two indexing plungers 7. The connecting block 2 is fixed in the pre-drilled hole groove of the synchronous belt 1. The connecting block 2 passes through the hole on the synchronous belt 1 and is fixed to the transmission block 3 above. The transmission block 3 and the connecting block 2 clamp the synchronous belt 1. The lower part of the head slider 4 is provided with a four-way closed and two-way open dug hole, and the transmission block 3 can slide in along the opening direction. Due to the special design shape of the transmission block 3, the up and down directions are fixed after sliding in. The upper part of the head slider 4 is connected and fixed to the belt 5 and the head clip 6. Two indexing plungers 7 are installed on the head clip 6. When the indexing plunger 7 is pressed down, the pin is inserted into the small hole reserved above the transmission block 3, and the front and back directions of the transmission block are restricted. When the synchronous belt pulley drives the synchronous belt 1 to move, the transmission block 3 fixed on the synchronous belt 1 drives the flexible belt card holder to move. When the double-chain arrangement device needs to replace the flexible belt card holder, only need to pull up the indexing plunger pin 7 and push forward to make the transmission block 3 slide out of the head slider 4 to complete the removal.

[0031] Furthermore, the lower end of the slider is connected to the upper end of the transmission block through a quick-release movable connection structure, and the quick-release movable connection structure includes a card slot on the slider, and the transmission block is sleeved or clamped with the card slot of the slider.

[0032] Furthermore, the connecting block 2 is fixed in the pre-drilled hole groove of the synchronous belt 1, and the transmission block 3 cooperates to clamp above the synchronous belt 1.

[0033] Furthermore, the transmission block 3 is designed to be mushroom-shaped. When it slides into the groove of the same shape reserved in the head slide body 4, the up and down directions will be restricted by itself and no relative displacement will occur.

[0034] Furthermore, the fixing point of the head slide 4 and the transmission block 3 is a four-way closed and two-way open type. When the transmission block 3 slides in, the indexing plunger 7 fixed on the head slide 4 will extend a small pin and fit into the small hole reserved on the top of the transmission block 3, thereby limiting the last free direction and fixing the entire structure.

[0035] Furthermore, after the connecting block 2 is fixed in the pre-punched hole groove of the synchronous belt 1, the side fixed with the transmission block 3 should be higher than the belt surface. When fixed with the transmission block 3, it is actually clamping between the two workpieces, rather than locking and fixing by squeezing the synchronous belt 1.

[0036] Furthermore, including but not limited to the indexing plunger 7, all kinds of elastic pins can achieve this function.

[0037] Furthermore, guide rails are arranged on both sides of the synchronous belt, and the slide body is slidably connected to the guide rails; the guide rails are generally concave in shape, and protrusions are provided at both ends of the slide body, and the protrusions are embedded in corresponding U-shaped slide grooves.

[0038] When the slider slides in the guide rail, the upper surface of the protrusion contacts the upper surface of the U-shaped groove on the side of the guide rail, which solves the problem of the slider jumping up and down when the transmission block drives the slider forward; only under feeding conditions, when the slider steps forward, the protrusions at both ends of the slider will contact the guide rail, avoiding unnecessary contact and increasing sliding resistance.

[0039] Furthermore, the transmission block 3 and the head slide 4 are fixed in all directions. However, when the transmission block 3 is suddenly started or stopped, the synchronous belt 1 will be flexibly deformed, causing the slide 4 to jump up and down. The upper surface of the U-shaped slide groove on the side of the concave guide rail 11 limits the upper surface of the bosses at both ends of the slide 4 to ensure the smooth movement of the slide 4.

[0040] Furthermore, only under the feeding condition, when the slide body 4 steps forward, the protrusions at both ends of the slide body 4 will contact with the guide rail 11, thereby avoiding unnecessary contact and increasing sliding resistance.

[0041] Furthermore, a holder is connected to the belt to form a flexible holder.

[0042] Working principle of the present invention: After lifting the indexing plunger 7 upwards and rotating it clockwise by 90°, the indexing plunger 7 can achieve self-locking. Push the head clip 6 in the advancing direction of the belt 5, so that the transmission block 3 slides out of the head slider 4. Then lift the head clip upwards, and cooperate with the belt turnover guide rail of the double-ring chain arrangement device to realize the rapid disassembly of the flexible belt card seat. For the installation process, just push the flexible belt card seat into the guide rail groove, push the head slider 4 into the transmission block 3, and rotate the indexing plunger 7 counterclockwise by 90°, then the installation of the flexible belt card seat can be completed.

[0043] Refer to Figure 1 、 Figure 2 As shown, a quick replacement method for the flexible belt card seat of a double-ring chain arrangement device of the present invention includes two synchronous belts 1, two connecting blocks 2, two transmission blocks 3, a head slider 4, a belt 5, a head clip 6, and two indexing plungers 7. The connecting block 2 is fixed in the pre-drilled hole groove of the synchronous belt 1. The connecting block 2 passes through the hole on the synchronous belt 1 and is fixed to the transmission block 3 above. The transmission block 3 and the connecting block 2 clamp the synchronous belt 1. The lower part of the head slider 4 is provided with a four-way closed and two-way open card slot, and the transmission block 3 can slide in along the opening direction. Due to the special designed shape of the transmission block 3, after sliding in, the up and down directions are fixed. The upper part of the head slider 4 is connected and fixed to the belt 5 and the head clip 6. Two indexing plungers 7 are installed on the head clip 6. When the indexing plunger 7 is pressed down, the pin is inserted into the reserved pin hole above the transmission block 3, and the front and back directions of the transmission block are restricted. When the synchronous belt wheel drives the synchronous belt 1 to move, the transmission block 3 fixed on the synchronous belt 1 drives the flexible belt card seat to move. When the double-ring chain arrangement device needs to replace the flexible belt card seat, only need to pull up the indexing plunger pin 7 and push it forward to make the transmission block 3 slide out of the head slider 4 to complete the removal.

[0044] Refer to Figure 3 、 Figure 4 The transmission block is designed in a mushroom shape. After sliding into the same-shaped notch reserved in the head slider, the up and down directions will be restricted by itself and there will be no relative displacement.

[0045] Refer to Figure 3 、 Figure 4 The fixed part of the head slider 4 and the transmission block 3 is four-way closed and two-way open. When the transmission block 3 slides in, the indexing plunger 7 fixed on the head slider 4 will extend a small pin and snap into the pin hole reserved at the top of the transmission block 3 to restrict the last free direction and realize the fixation of the whole structure.

[0046] Furthermore, the transmission block is provided with counterbore holes, and bolts are arranged in the counterbore holes and connected to the connecting block.

[0047] Furthermore, the number of counterbore holes is two, and the two counterbore holes are arranged on both sides of the pin hole 9.

[0048] Further, the synchronous belt is provided with holes and grooves, the connecting block is embedded in the holes and grooves, the driving block passes through the holes and grooves and is fixedly connected with the connecting block, and the driving block and the connecting block clamp the synchronous belt.

[0049] Further, both sides of the card slot 8 are provided with grooves, both sides of the driving block 3 are provided with bumps 10, and when the driving block 3 slides into the card slot, the bumps 10 are clamped into the corresponding grooves.

[0050] The above are only the preferred embodiments of the present invention, and of course, the scope of rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the protection scope of the present invention.
