[0024] 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.

[0025] Example 1: Please refer to Figures 1 to 4 The present invention provides the following technical solution:

[0026] A limit frame for an easily movable and unloading NMP solution recovery tank includes a support chassis 1. Equally spaced moving clamps 2 are slidably connected to the top of the support chassis 1. An adjustment assembly is installed at the bottom of the support chassis 1. The adjustment assembly includes a scissor-type telescopic assembly installed at the bottom of the support chassis 1. The scissor-type telescopic assembly is composed of X-shaped connecting rods 3 hinged together, with a hinge shaft 4 at each hinge point. A through groove distributed along the length of the support chassis 1 is provided in the middle. The hinge shafts 4 installed in the middle of the connecting rods 3 extend through the through groove to the top of the support chassis 1, and the hinge shafts 4 are equally spaced within the through groove. The hinge shaft 4 in the middle of the scissor-type telescopic assembly is fixedly connected to the middle of the support chassis 1.

[0027] The bottom middle of the motion clamping plates 2 located at both ends of the top of the support chassis 1 is fixedly connected to the hinge shafts 4 at both ends of the scissor-type telescopic assembly. An adjusting slider 6 is fixedly connected to the bottom of the hinge shaft 4. Two vertically distributed clamping bars 5 are fixedly connected to the side of the adjacent motion clamping plates 2 that are close to each other. The clamping bars 5 on the two motion clamping plates 2 are aligned with each other and have an arc-shaped structure.

[0028] A guide rail 7 is fixedly connected to the bottom center of the support chassis 1. The guide rail 7 is aligned with the through groove in the middle of the support chassis 1. Both ends of the guide rail 7 are fixedly connected to the bottom of the support chassis 1. The guide rail 7 and the connecting rod 3 do not interfere with each other. A reverse screw 8 is rotatably connected to the inside of the guide rail 7. Both ends of the reverse screw 8 are rotatably connected to the two ends of the guide rail 7. The adjusting slider 6 is slidably connected to the inside of the guide rail 7. The adjusting slider 6 is threadedly connected to the outside of the reverse screw 8. Fixed universal wheels 11 are fixedly connected to the four corners of the bottom of the support chassis 1.

[0029] The reverse lead screw 8 is provided with a bevel gear at its end. Both ends of the support chassis 1 are fixedly connected with push handles 10. The middle of the push handle 10 is rotatably connected to a drive shaft 9 through a bracket. The upper end of the drive shaft 9 is fixedly connected with a rotating handle, and the lower end of the drive shaft 9 is provided with a bevel gear that meshes with the bevel gear at the end of the reverse lead screw 8.

[0030] In the initial state, the moving clamps 2 are evenly distributed along the top of the supporting chassis 1, and the scissor-type telescopic assembly is in a natural telescopic state. When it is necessary to limit and clamp NMP solution recovery tanks of different sizes, the operator can rotate the rotating handle at the upper end of the drive shaft 9. The drive shaft 9 then rotates around the bracket in the middle of the push handle 10. Since the bevel gear at the lower end of the drive shaft 9 meshes with the bevel gear at the end of the reverse lead screw 8, the reverse lead screw 8 will rotate along the inner side of the guide rail 7 under the drive of the drive shaft 9. The adjusting slider 6 is threaded to the outside of the reverse lead screw 8 and slidably connected to the inside of the guide rail 7. The guide rail 7 forms a circumferential limit on the adjusting slider 6, so that the rotation of the reverse lead screw 8 is converted into the linear movement of the adjusting slider 6 along the guide rail 7. The two adjusting sliders 6 can move towards or away from each other as the reverse lead screw 8 rotates.

[0031] The adjusting slider 6 is fixedly connected to the hinge shafts 4 at both ends of the scissor-type telescopic assembly, while the hinge shaft 4 in the middle of the scissor-type telescopic assembly is fixed to the middle of the supporting base 1. Therefore, when the hinge shafts 4 at both ends move with the adjusting slider 6, the scissor-type telescopic assembly will undergo telescopic deformation, and the X-shaped included angle between the connecting rods 3 will increase or decrease accordingly. At the same time, the hinge shaft 4 in the middle will slide synchronously in the through groove of the supporting base 1 and always maintain an equidistant distribution.

[0032] The hinge shaft 4 extending to the top of the support chassis 1 will drive the connected moving clamp 2 to slide along the top of the support chassis 1, thereby changing the distance between adjacent moving clamps 2. When the moving clamp 2 moves to a position that matches the size of the recycling tank, the upper and lower arc-shaped clamping strips 5 on the side of the adjacent moving clamps 2 will align and fit against the outer wall of the recycling tank, thereby achieving the limiting clamping of the recycling tank. When it is necessary to move the entire limiting frame and the recycling tank, the operator can push the handle 10 in conjunction with the fixed universal wheels 11 at the four corners of the bottom of the support chassis 1 to drive the entire device to move smoothly.

[0033] Example 2: Based on Example 1, please refer to... Figures 3 to 6 The following structure was also disclosed:

[0034] A fixed plate 12 is fixedly connected to the top center of the support chassis 1. Adjustment plates 13, which are symmetrically distributed on both sides of the fixed plate 12, are slidably connected to the top of the support chassis 1. Motion plates 16 are slidably connected to the top outer sides of both the fixed plate 12 and the adjustment plates 13. The fixed plate 12 and the adjustment plates 13 are located between two motion clamps 2.

[0035] One end of the adjustment plate 13 is provided with a mounting hole 14. A positioning block 15 with a spherical structure at the upper end is slidably connected inside the mounting hole 14. A spring is fixedly connected between the positioning block 15 and the mounting hole 14. A loading area 17 is provided in the middle of the moving plate 16.

[0036] One end of the motion plate 16 is provided with a positioning hole 18 aligned with the mounting hole 14. The positioning block 15 is engaged and connected inside the positioning hole 18. A pull handle 19 is fixedly connected to one end of the motion plate 16 near the positioning hole 18. The other end of the motion plate 16 near the positioning hole 18 is wrapped around the outside of the adjustment plate 13. A movable universal wheel 20 is fixedly connected to the bottom of this end of the motion plate 16. The bottom of the movable universal wheel 20 is flush with the bottom of the fixed universal wheel 11.

[0037] After initial positioning of the recycling tank, the fixed plate 12 and the adjusting plate 13 provide support from the bottom of the tank. The operator can slide the adjusting plate 13 according to the length of the recycling tank, changing the distance between the adjusting plate 13 and the fixed plate 12 to adapt the support structure to the size of the recycling tank. The moving plate 16 is fixed to the top of the fixed plate 12 and the adjusting plate 13 via a positioning structure. Under the elastic force of the spring, the spherical upper end of the positioning block 15 in the mounting hole 14 of the adjusting plate 13 engages with the positioning hole 18 of the moving plate 16, thereby restricting the sliding of the moving plate 16. The loading area 17 in the middle of the moving plate 16 supports the recycling tank.

[0038] When it is necessary to move and unload, the operator pulls the pull handle 19 at the end of the moving plate 16 outward. After the moving plate 16 is subjected to force, the inner wall of the positioning hole 18 will exert a squeezing force on the upper spherical end of the positioning block 15, forcing the positioning block 15 to compress the spring and retract into the mounting hole 14. At this time, the restriction of the positioning structure on the moving plate 16 is released, and the moving plate 16 can slide along the top outer side of the fixed plate 12 and the adjusting plate 13. Since the bottom of the moving plate 16 near the positioning hole 18 is fixed with a movable universal wheel 20, and the bottom of the movable universal wheel 20 is flush with the bottom of the fixed universal wheel 11, the movable universal wheel 20 can provide stable support for the moving plate 16 during the sliding process.

[0039] The operator can pull the moving plate 16 and the recycling tank it carries out smoothly from the limit frame by pulling the handle 19 to complete the unloading operation. After unloading, the moving plate 16 is pushed to reset along the fixed plate 12 and the adjusting plate 13. When the positioning block 15 is aligned with the positioning hole 18 again, the positioning block 15 will be re-engaged into the positioning hole 18 under the elastic force of the spring, so as to realize the reset and fixation of the moving plate 16.
