[0016] 1. Through the setting of the buffer mechanism, the sleeve of the present utility model can obtain a buffering effect. When the sleeve is subjected to impact vibration, the sleeve will drive the bearing seats on both sides to move synchronously. When the bearing seats move, the first combined plate can move, enabling the connecting rod to rotate and pushing the movable blocks on both sides to move in opposite directions. As a result, the damping springs can be compressed to buffer the vibration and impact force received by the bearing seats. Moreover, during this process, the air springs can also expand and contract, and the air springs can further provide a buffering effect for the bearing seats, enabling the sleeve to be in a stable state during operation and preventing the surface from being damaged by impact.

[0017] 2. Through the setting of the disassembly and assembly mechanism, the printing plate on the surface of the sleeve of the present utility model can be quickly replaced. When the printing plate on the surface of the sleeve needs to be replaced, the movable linkage plate is actuated, causing the slider to slide from the surface of the first guide rail to the surface of the second guide rail. Then, the storage plate is rotated downward, enabling the right bearing seat to disengage from the surface of the sleeve. Thus, the operator can quickly remove and replace the printing plate on the surface of the sleeve.

[0018] 3. Through the setting of the height adjustment mechanism, the height of the sleeve of the present utility model can be adjusted. When the motor is started, it drives the first bevel gear to rotate through the drive shaft, and the first bevel gear can drive a plurality of lead screws to rotate synchronously through meshing with the second bevel gear. As a result, the pushing frame can drive the top plate to move up and down under the influence of the thread, thereby changing the height position of the sleeve and improving the height adaptability of the sleeve.

[0027] Please refer to Figures 1-7 , an embossing sleeve buffer support frame, including a support mechanism 1, and a buffer mechanism 2, a disassembly and assembly mechanism 3, and a lifting mechanism 4 are arranged on the surface of the support mechanism 1;

[0028] The buffer mechanism 2 enables the sleeve 103 to obtain a buffering effect, the disassembly and assembly mechanism 3 enables the printing plate on the surface of the sleeve 103 to be quickly replaced, and the lifting mechanism 4 enables the height of the sleeve 103 to be adjusted.

[0029] The support mechanism 1 includes a bottom plate 101, a top plate 102 and a sleeve 103;

[0030] The buffer mechanism 2 includes two mounting plates 201. The left mounting plate 201 is fixed to the top of the top plate 102. Two first extension plates 202 are fixed to the top of the mounting plate 201. A connecting plate 203 is fixed to the top of the first extension plate 202. A bearing seat 206 is arranged above the mounting plate 201. Second combined plates 213 are fixed to both the top and bottom of the bearing seat 206. A first combined plate 209 is fixed to the surface of the second combined plate 213. Two connecting rods 208 are hinged to the surface of the first combined plate 209. A movable block 207 is hinged to the surface of the connecting rod 208. A damping spring 205 is fixed to the surface of the movable block 207. A U-shaped plate 204 is arranged on one side of the first combined plate 209. Two damping springs 205 are fixed to the surface of the U-shaped plate 204. One end of the damping spring 205 is fixedly connected to the surface of the movable block 207. A top block 210 is fixed to the surface of the U-shaped plate 204. An air spring 211 is fixed to the surface of the top block 210. One end of the air spring 211 is fixedly connected to the surface of the first combined plate 209. The surface of the upper U-shaped plate 204 is fixedly connected to the surface of the connecting plate 203. The surface of the lower U-shaped plate 204 is fixedly connected to the surface of the mounting plate 201. The inner wall of the left bearing seat 206 is fixedly connected to the surface of the sleeve 103. The inner wall of the right bearing seat 206 is movably connected to the surface of the sleeve 103;

[0031] When the sleeve 103 is subjected to impact vibration, the sleeve 103 will drive the two bearing seats 206 to move synchronously. When the bearing seat 206 moves, the first combined plate 209 can move, enabling the connecting rod 208 to rotate and pushing the two movable blocks 207 to move in opposite directions. As a result, the damping spring 205 can be compressed to buffer the vibration and impact force received by the bearing seat 206. And during this process, the air spring 211 can also expand and contract, and the air spring 211 can further provide a buffering effect for the bearing seat 206, enabling the sleeve 103 to be in a stable state during operation and preventing the surface from being damaged by impact.

[0032] Furthermore, a telescopic rod 212 is fixed to the surface of the top block 210. One end of the telescopic rod 212 is fixedly connected to the surface of the movable block 207;

[0033] The telescopic rod 212 can expand and contract, enabling the movable block 207 to obtain a guiding effect and preventing the movable block 207 from detaching from the surface of the U-shaped plate 204.

[0034] Further, the disassembly and assembly mechanism 3 includes first guide rails 301. The number of the first guide rails 301 is two. The first guide rails 301 are fixed to the right side of the top of the top plate 102. A slider 302 is slidably connected to the surface of the first guide rail 301. A linkage plate 303 is fixed to the top of the slider 302. The top of the linkage plate 303 is fixedly connected to the bottom of the right mounting plate 201. Second extension plates 304 are fixed to the front and rear sides of the surface of the top plate 102. A rotating shaft 305 is rotatably connected to the surface of the second extension plate 304. A storage plate 306 is fixed to the surface of the rotating shaft 305. Two second guide rails 307 are fixed to the surface of the storage plate 306;

[0035] When the printing plate on the surface of the sleeve 103 needs to be replaced, move the linkage plate 303 to make the slider 302 slide from the surface of the first guide rail 301 to the surface of the second guide rail 307, and then rotate the storage plate 306 downward so that the right bearing block 206 can be separated from the surface of the sleeve 103, so that the operator can quickly take out and replace the printing plate on the surface of the sleeve 103.

[0036] Further, a knob 309 is threadedly penetrated through the surface of the linkage plate 303, and a plurality of positioning holes for cooperating with the knob 309 are opened on the surface of the top plate 102;

[0037] Rotating the knob 309 can make it enter the positioning hole, so that the linkage plate 303 can be fixed, avoiding the situation that the linkage plate 303 moves by itself when the sleeve 103 is in use.

[0038] Further, a limiting plate 308 is fixed to the surface of the storage plate 306. A pin rod 310 is slidably penetrated through the surface of the second extension plate 304. A limiting hole for cooperating with the pin rod 310 is opened on the surface of the storage plate 306;

[0039] The limiting plate 308 can limit the linkage plate 303 to prevent the linkage plate 303 from driving the slider 302 to fall off the surface of the second guide rail 307. Passing the pin rod 310 through the second extension plate 304 can make it enter the limiting hole, so that the storage plate 306 can be limited.

[0040] Further, the lifting mechanism 4 includes a mounting frame 401 and a motor 402. The mounting frame 401 and the motor 402 are both fixed to the surface of the bottom plate 101. A driving shaft 403 is fixed to the output shaft of the motor 402. One end of the driving shaft 403 is rotatably connected to the surface of the bottom plate 101. A pushing frame 404 is fixed to the bottom of the top plate 102. A plurality of lead screws 405 are rotatably connected to the bottom of the mounting frame 401. The lead screws 405 are threadedly penetrated through the pushing frame 404. A plurality of first bevel gears 406 are fixed to the surface of the driving shaft 403. A second bevel gear 407 is fixed to the bottom end of the lead screw 405. The first bevel gear 406 is engaged with the second bevel gear 407;

[0041] When the motor 402 starts, it drives the first bevel gear 406 to rotate through the drive shaft 403. The first bevel gear 406 can drive multiple lead screws 405 to rotate synchronously through meshing with the second bevel gear 407, so that the pushing frame 404 can drive the top plate 102 to move up and down under the influence of the thread, thereby changing the height position of the sleeve 103 and improving the height adaptability of the sleeve 103.

[0042] Furthermore, a plurality of guide rods 409 are fixed on the surface of the bottom plate 101. The tops of the guide rods 409 are fixedly connected to the surface of the mounting frame 401. A plurality of sliding sleeves 408 are fixed on the surface of the pushing frame 404. The sliding sleeves 408 are slidably connected to the surfaces of the guide rods 409.

[0043] When the pushing frame 404 moves, the sliding sleeves 408 can slide on the surfaces of the guide rods 409, so that the pushing frame 404 can obtain a guiding effect, thereby improving the stability of the top plate 102 and the pushing frame 404 when moving.

[0044] Furthermore, rectangular bellows 104 are fixed on the surfaces of both the bottom plate 101 and the second combined plate 213. The top of the rectangular bellows 104 on the surface of the upper second combined plate 213 is fixedly connected to the surface of the connecting plate 203. The bottom of the rectangular bellows 104 on the surface of the lower second combined plate 213 is fixedly connected to the top of the mounting plate 201. The top of the rectangular bellows 104 on the surface of the bottom plate 101 is fixedly connected to the bottom of the top plate 102.

[0045] The rectangular bellows 104 can expand and contract, thereby preventing the hands or feet of a person from entering between the bottom plate 101 and the top plate 102, and preventing foreign objects from entering between the second combined plate 213 and the mounting plate 201 and the connecting plate 203, thereby preventing the structure from being stuck due to foreign object blockage.
