Description

Technical Field

[0001] This utility model relates to the field of rotary cutting roller technology, and in particular to a novel rotary cutting roller assembly structure. Background Technology

[0002] Currently, rotary die-cutting technology is being used more and more widely, with applications in industries such as non-woven fabrics, leather products, electronic products, plastic products, medical dressings, packaging, printing, household paper, metal foil, PE and PP films, etc. These industries require rotary cutting rollers for material processing.

[0003] Common new rotary cutting roller assembly structures only include the function of rotary cutting, which can perform rotary cutting of materials, but lack the function of quick blade replacement. They cannot guarantee quick blade replacement and are prone to the blades being welded to the roller as a whole. In this case, after the blades are damaged or their sharpness decreases, the entire roller needs to be replaced, or the blades need to be ground and re-welded, which affects the processing efficiency.

[0004] Therefore, to address the lack of a quick blade replacement function in the aforementioned novel rotary cutting roller assembly structure, a new rotary cutting roller assembly structure can be designed. When blade replacement is required, the bolts are removed, thus freeing the movable protective ring from the roller body. The movable protective ring is then pulled out from around the roller body, allowing the roller sleeve to be removed as well. After the roller sleeve with a damaged or diminished blade is removed, a new roller sleeve can be fitted around the roller body, ensuring quick blade replacement. Utility Model Content

[0005] To overcome the common problem of lacking a quick-change blade function in the assembly structure of new rotary cutting rollers, which cannot guarantee the ability to quickly change blades, the blades on the roller are often welded together. This means that when the blades are damaged or their sharpness decreases, the entire roller needs to be replaced, or the blades need to be ground and re-welded, which affects processing efficiency.

[0006] The technical solution of this utility model is as follows: a novel rotary cutting roller assembly structure, including a cutter shaft body; further including a cutter roller body, a roller sleeve, a first limiting ring, a first limiting block, a movable protective ring, a first annular groove, a first limiting groove, an internal threaded hole, a fixing hole, and bolts. The cutter roller body is fitted around the middle of the cutter shaft body, and the roller sleeve is fitted around the cutter roller body. A first limiting ring is provided on the right side of the roller sleeve. Several first limiting blocks are arranged at equal intervals around the first limiting ring. A movable protective ring is fitted on the right side of the cutter roller body. A first annular groove is opened on the left side of the movable protective ring corresponding to the position of the first limiting ring. Several first limiting grooves are opened at equal intervals on the left side of the movable protective ring corresponding to the positions of the first annular groove and the first limiting block. Four internal threaded holes are opened at equal intervals on the right side of the cutter roller body. Four fixing holes are opened at equal intervals around the movable protective ring corresponding to the positions of the internal threaded holes. Bolts are installed inside the fixing holes.

[0007] Preferably, when the blade needs to be replaced, the bolts are removed, so that the movable protective ring is not fixed to the blade roller body. Then, the movable protective ring is pulled out from the blade roller body, and then the roller sleeve can be pulled out from the blade roller body. After the roller sleeve with a damaged blade or reduced sharpness is removed, a new roller sleeve can be fitted around the blade roller body, thus ensuring that the blade can be replaced quickly. This solves the problem that common new rotary cutting blade roller assembly structures only have the function of rotary cutting, which can perform rotary cutting of materials, but lack the function of quick blade replacement. They cannot guarantee quick blade replacement and are prone to the blades on the blade roller being welded to the blade roller as a whole. In this case, after the blade is damaged or reduced in sharpness, the entire blade roller needs to be replaced, or the blade needs to be ground and re-welded, which affects the processing efficiency.

[0008] Preferably, the first limiting ring is inserted into the inside of the first annular groove, and the first limiting block is inserted into the inside of the first limiting groove.

[0009] Preferably, the movable protective ring is connected to the cutter roller body by bolts passing through the movable protective ring and then screwing it into the internal threaded hole.

[0010] Preferably, a second limiting ring is provided on the left side of the roller sleeve, and several second limiting blocks are provided at equal intervals around the second limiting ring.

[0011] Preferably, a fixed protective ring is provided on the left side of the cutter roller body corresponding to the position of the second limiting ring. The fixed protective ring is welded to the cutter roller body as a whole, and two blades are symmetrically arranged in the middle of the roller surface sleeve.

[0012] Preferably, a second annular groove is provided on the right side of the fixed protective ring corresponding to the position of the second limiting ring, and several second limiting grooves are provided on the right side of the fixed protective ring at equal intervals corresponding to the positions of the second annular groove and the second limiting block.

[0013] Preferably, the second limiting ring is inserted into the interior of the second annular groove, and the second limiting block is inserted into the interior of the second limiting groove.

[0014] The beneficial effects of this utility model are:

[0015] 1. When it is necessary to replace the blade, remove the bolts so that the movable protective ring is not fixed to the cutter roller body. Then, pull the movable protective ring out from the cutter roller body, and then pull the roller sleeve out from the cutter roller body. After the roller sleeve with a damaged or dull blade is removed, a new roller sleeve can be fitted around the cutter roller body, thus ensuring that the blade can be replaced quickly. This solves the problem of common new rotary cutting cutter roller assembly structures that only have the function of rotary cutting, which can perform rotary cutting of materials, but lack the function of quick blade replacement. They cannot guarantee quick blade replacement and are prone to the blades on the cutter roller being welded to the cutter roller as a whole. In this case, after the blade is damaged or dulled, the entire cutter roller needs to be replaced, or the blade needs to be ground and re-welded, which affects the processing efficiency.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment: a novel rotary cutting roller assembly structure, including a cutter shaft body 1; and also including a cutter roller body 2, a roller sleeve 3, a first limiting ring 4, a first limiting block 5, a movable protective ring 6, a first annular groove 7, a first limiting groove 8, an internal threaded hole 9, a fixing hole 10, and a bolt 11. The cutter roller body 2 is fitted around the middle of the cutter shaft body 1, and the roller sleeve 3 is fitted around the cutter roller body 2. The first limiting ring 4 is provided on the right side of the roller sleeve 3, and several first limiting blocks 5 are arranged at equal intervals around the first limiting ring 4. The movable protective ring 6 is fitted on the right side of the cutter roller body 2. A first annular groove 7 is opened on the left side of the movable protective ring 6 corresponding to the position of the first limiting ring 4. Several first limiting grooves 8 are opened at equal intervals on the left side of the movable protective ring 6 corresponding to the positions of the first annular groove 7 and the first limiting block 5. Four internal threaded holes 9 are opened at equal intervals on the right side of the cutter roller body 2, and four internal threaded holes 9 are opened at equal intervals around the movable protective ring 6 corresponding to the positions of the internal threaded holes 9. There are four fixing holes 10, and bolts 11 are installed inside the fixing holes 10. When it is necessary to replace the blade 17, the bolts 11 are removed, so that the movable protective ring 6 is not fixed to the blade roller body 2. Then the movable protective ring 6 is pulled out from the blade roller body 2, and then the roller sleeve 3 can be pulled out from the blade roller body 2. After the roller sleeve 3 with the blade 17 damaged or reduced sharpness is removed, a new roller sleeve 3 can be put on the blade roller body 2, thus ensuring that the blade 17 can be quickly replaced. This solves the problem that the common new rotary cutting blade roller assembly structure only has the function of rotary cutting, which can perform rotary cutting of materials, but lacks the function of quick replacement of blade 17. It cannot guarantee that the blade 17 can be quickly replaced. It is easy for the blade 17 on the blade roller to be welded to the blade roller as a whole. In this case, after the blade 17 is damaged or reduced in sharpness, the entire blade roller needs to be replaced, or the blade 17 needs to be ground and re-welded, which affects the processing efficiency.

[0023] Please see Figures 2-4 In this embodiment, a fixed protective ring 14 is provided on the left side of the cutter roller body 2 corresponding to the position of the second limiting ring 12. The fixed protective ring 14 is welded to the cutter roller body 2 as a whole. Two blades 17 are symmetrically arranged in the middle of the roller surface sleeve 3. A second annular groove 15 is opened on the right side of the fixed protective ring 14 corresponding to the position of the second limiting ring 12. Several second limiting grooves 16 are opened at equal intervals on the right side of the fixed protective ring 14 corresponding to the positions of the second annular groove 15 and the second limiting block 13. The second limiting ring 12 is inserted into the inside of the second ring groove 15, and the second limiting block 13 is inserted into the inside of the second limiting groove 16. When it is necessary to replace the blade 17, the bolt 11 is removed so that the movable protective ring 6 is not fixed to the blade roller body 2. Then the movable protective ring 6 is pulled out from the periphery of the blade roller body 2, and then the roller sleeve 3 can be pulled out from the periphery of the blade roller body 2. After the roller sleeve 3 with the blade 17 damaged or reduced sharpness is removed, a new roller sleeve 3 can be fitted around the periphery of the blade roller body 2.

[0024] Please see Figures 1-4 In this embodiment, the first limiting ring 4 is inserted into the interior of the first annular groove 7, the first limiting block 5 is inserted into the interior of the first limiting groove 8, and the movable protective ring 6 is screwed into the interior of the internal threaded hole 9 after passing through the movable protective ring 6 with a bolt 11 and connected to the cutter roller body 2. A second limiting ring 12 is provided on the left side of the roller sleeve 3, and several second limiting blocks 13 are provided at equal intervals around the second limiting ring 12. After the new roller sleeve 3 is fitted around the cutter roller body 2, the new roller sleeve 3 is pushed towards the fixed protective ring 14, so that the second limiting ring 12 is inserted into the interior of the second annular groove 15 and the second limiting block 13 is inserted into the interior of the second limiting groove 16. Then the movable protective ring 4 is inserted into the interior of the first limiting groove 7. The protective ring 6 is fitted around the cutter roller body 2, and the movable protective ring 6 is pushed towards the new roller surface sleeve 3 until the first limiting ring 4 is inserted into the first ring groove 7 and the first limiting block 5 is inserted into the first limiting groove 8. Finally, the bolt 11 is screwed into the inner threaded hole 9 after passing through the movable protective ring 6, thereby fixing the cutter roller body 2 and the movable protective ring 6. This realizes the function of quickly replacing the blade 17 and prevents the blade 17 on the cutter roller from being welded to the cutter roller as a whole. In this case, if the blade 17 is damaged or its sharpness decreases, the entire cutter roller needs to be replaced, or the blade 17 needs to be ground and re-welded, which affects the processing efficiency.

[0025] When it is necessary to replace the blade 17 during operation, remove the bolt 11 to prevent the movable protective ring 6 from being fixed to the cutter roller body 2. Then, pull the movable protective ring 6 out from around the cutter roller body 2. Next, pull the roller sleeve 3 out from around the cutter roller body 2. After removing the roller sleeve 3 with a damaged blade 17 or reduced sharpness, install a new roller sleeve 3 around the cutter roller body 2. After the new roller sleeve 3 is installed, push it towards the fixed protective ring 14, thereby causing the second limit... The retaining ring 12 is inserted into the inside of the second annular groove 15, and the second limiting block 13 is inserted into the inside of the second limiting groove 16. Then, the movable protective ring 6 is fitted around the body of the cutter roller 2 and pushed towards the new roller surface sleeve 3 until the first limiting ring 4 is inserted into the inside of the first annular groove 7 and the first limiting block 5 is inserted into the inside of the first limiting groove 8. Finally, the bolt 11 is screwed into the inner threaded hole 9 after passing through the movable protective ring 6, thereby fixing the cutter roller 2 and the movable protective ring 6, realizing the function of quickly changing the blade 17.

[0026] Through the above steps, when the blade 17 needs to be replaced, the bolt 11 is removed, so that the movable protective ring 6 is not fixed to the blade roller body 2. Then, the movable protective ring 6 is pulled out from the blade roller body 2, and then the roller sleeve 3 can be pulled out from the blade roller body 2. After the roller sleeve 3 with the blade 17 damaged or with reduced sharpness is removed, a new roller sleeve 3 can be fitted around the blade roller body 2, thus ensuring that the blade 17 can be quickly replaced. This solves the problem that common new rotary cutting blade roller assembly structures only include the function of rotary cutting, which can perform rotary cutting of materials, but lack the function of quickly replacing the blade 17. It cannot guarantee that the blade 17 can be quickly replaced. It is easy for the blade 17 on the blade roller to be welded to the blade roller as a whole. In this case, after the blade 17 is damaged or its sharpness is reduced, the entire blade roller needs to be replaced, or the blade 17 needs to be ground and re-welded, which affects the processing efficiency.
