[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying Figure 1-7 drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] As shown in the figure, a cutting device for producing Christmas ornaments includes a frame 1. A traction mechanism 2 and a cutting mechanism 3 are arranged on the frame 1. The cutting mechanism 3 includes a hydraulic cylinder 31, a driving plate 32, a first mounting plate 33, a second mounting plate 34 and a cutter 35. The driving plate 32 is longitudinally slidably arranged on the frame 1 through a linear guide rail 12 arranged on the frame 1. The hydraulic cylinder 31 is arranged on the frame 1 and connected to the driving plate 32. The first mounting plate 33 is arranged on the driving plate 32. The second mounting plate 34 is hinged to the first mounting plate 33. An installation ring 351 is formed at the end of the cutter 35. A number of installation holes 341 for the cutter 35 to pass through are formed on the second mounting plate 34. An installation groove 342 matching the installation ring 351 is formed at the port of the installation hole 341 facing the second mounting plate 34. The cutter 35 passes through the installation hole 341 to place the installation ring 351 in the installation groove 342. The second mounting plate 34 swings towards the first mounting plate 33, fits against the first mounting plate 33 and is fastened to the first mounting plate 33 through a fastening component, so that the first mounting plate 33 presses and holds the installation ring 351 in the installation groove 342. A supporting plate 11 located below the cutter 35 is arranged on the frame 1.
[0025] Specifically, the traction mechanism 2 includes a first conveyor belt 21 and a second conveyor belt 22. The two first conveyor belts 21 are arranged on the frame 1 on both sides of the supporting plate 11 respectively. The two second conveyor belts 22 are arranged on the frame 1 above the two first conveyor belts 21 respectively.
[0026] Specifically, the fastening component includes a locking screw 331 and a locking nut 332. The locking screw 331 is hinged to the first mounting plate 33. A locking groove 343 matching the locking screw 331 is formed on the side end of the second mounting plate 34. The locking screw 331 swings and is clamped into the locking groove 343. The locking nut 332 is screwed onto the locking screw 331 and abuts against the second mounting plate 34.
[0027] In the above structure, when disassembling and assembling the cutting knife 35, loosen the locking nut 332, swing the locking screw rod 331 upward so that it exits from the locking groove 343, enable the second mounting plate 34 to swing relative to the first mounting plate 33 along the hinge axis, swing the second mounting plate 34 downward to drive the cutting knife 35 away from the first mounting plate 33, and make the mounting ring 351 leave the position pressed by the first mounting plate 33 to expose the mounting groove 342. At this time, the mounting ring 351 can be taken out from the mounting groove 342 and the cutting knife 35 can be withdrawn from the mounting hole 341 to realize the disassembly of the cutting knife 35. According to production needs, the cutting knife 35 with different shapes is passed through the mounting hole 341 so that the mounting ring 351 is placed in the mounting groove 342, and the second mounting plate 34 is swung towards the first mounting plate 33 to drive the cutting knife 35 to swing. When the second mounting plate 34 is in contact with the first mounting plate 33, the first mounting plate 33 presses on the mounting ring 351 to keep it in the mounting groove 342 and the cutting knife 35 is kept on the first mounting plate 33. Then, swing the locking screw rod 331 downward to engage it in the locking groove 343, and then tighten the locking nut 332 to fasten the first mounting plate 33 and the second mounting plate 34, and the installation of the cutting knife 35 can be realized. The disassembly and assembly operation of the above cutting knife 35 is very convenient, which is convenient to replace the cutting knife 35 with different shapes according to the production requirements of different-shaped parts of Christmas ornaments, thus facilitating the use in production and making the cutting device have better applicability. When cutting the parts of Christmas ornaments, materials such as felt, leather, and cardboard are placed on the supporting plate 11, and both ends of the materials are respectively inserted between the first conveyor belt 21 and the second conveyor belt 22. The operating first conveyor belt 21 and the second conveyor belt 22 drive the materials to intermittently move on the supporting plate 11 towards the lower part of the cutting knife 35 by clamping the side ends of the materials. When the materials move to the lower part of the cutting knife 35, the hydraulic cylinder 31 drives the driving plate 32, which drives the first mounting plate 33 and the second mounting plate 34, and then drives the cutting knife 35 to move downward. The downward-moving cutting knife 35 cuts into the materials and cooperates with the supporting plate 11 to cut out the parts of Christmas ornaments on the materials. After the cutting knife 35 is driven by the hydraulic cylinder 31 to reset, the first conveyor belt 21 and the second conveyor belt 22 drive the materials to continue to move forward a certain distance, and when the cutting knife 35 moves downward again, the materials are cut for the next time. Repeating like this, the parts of Christmas ornaments can be continuously cut out on the materials. In the above structure, the first conveyor belt 21 and the second conveyor belt 22 are common existing technologies and will not be elaborated too much. And a buffer spring can be set on the downward movement path of the driving plate 32 to buffer the movement of the cutting knife 35, which are all common means in the existing technologies and those skilled in the art can implement according to needs and will not be elaborated too much here.
[0028] In addition, a sliding block 333 with a T-shaped cross-section is fixedly connected to the first mounting plate 33. A sliding groove 321 that matches the sliding block 333 and penetrates through the driving plate 32 to one side is formed in the driving plate 32. The sliding block 333 is held in the sliding groove 321 so that the first mounting plate 33 is slidably connected to the driving plate 32. A limiting rod 334 is inserted through the first mounting plate 33. First limiting holes 322 and second limiting holes 323 that match the limiting rod 334 are respectively formed at both ends of the driving plate 32. A first spring 335 is arranged on the first mounting plate 33 and acts on the limiting rod 334 to make the limiting rod 334 have a tendency to slide towards the driving plate 32. When the limiting rod 334 slides towards the driving plate 32 under the action of the first spring 335 and is inserted into the first limiting hole 322, the cooperation between the limiting rod 334 and the first limiting hole 322 limits the sliding of the first mounting plate 33 relative to the driving plate 32. At this time, the cutting knife 35 is located above the supporting plate 11, and the first mounting plate 33 can stably move with the driving plate 32 to drive the second mounting plate 34 and the cutting knife 35 to perform the cutting operation on the Christmas ornament components. When the cutting knife 35 needs to be replaced, the limiting rod 334 is pulled downward to make it withdraw from the first limiting hole 322. At this time, the first mounting plate 33 can be pulled or pushed to slide relative to the driving plate 32. The first mounting plate 33 drives the second mounting plate 34 and the cutting knife 35 to slide relative to the driving plate 32. When the limiting rod 334 slides with the first mounting plate 33 to the second limiting hole 323, the limiting rod 334 is inserted into the second limiting hole 323 under the action of the first spring 335. At this time, the second mounting plate 34 completely leaves above the supporting plate 11, that is, the first mounting plate 33 and the second mounting plate 34 are slid to one side of the frame 1, providing a larger operating space for the operation of replacing the cutting knife 35 and further facilitating the replacement operation of the cutting knife 35. After the cutting knife 35 is replaced, the first mounting plate 33 and the second mounting plate 34 are pushed to slide on the driving plate 32 to the position where the limiting rod 334 is inserted into the first limiting hole 322.
[0029] Additionally, the cutting knife 35 has a hollow structure. A pressure rod 336 located inside the cutting knife 35 is fixedly connected to the first mounting plate 33. A pressure sleeve 337 is slidably disposed on the pressure rod 336. A second spring 338 acting on the pressure sleeve 337 to make the pressure sleeve 337 have a downward sliding tendency is sleeved on the pressure rod 336. When the cutting knife 35 swings relative to the first mounting plate 33 with the second mounting plate 34, the hollow-structured cutting knife 35 will not interfere with the pressure rod 336 and the pressure sleeve 337. In the natural state, the lower end of the pressure sleeve 337 abuts against the lower end of the cutting knife 35. When the cutting knife 35 moves downward to cut the components of the Christmas hanger, the pressure sleeve 337 first contacts the material and presses the material tightly. During the process of the cutting knife 35 cutting into the material, the pressure sleeve 337 always abuts against the material through the upward sliding of the pressure sleeve 337 on the pressure rod 336 and the restoring force of the second spring 338, ensuring the stability of the material when being cut by the cutting knife 35, thereby guaranteeing the quality of cutting. When the cutting knife 35 moves upward to withdraw from the material, the components of the Christmas hanger are retained on the material by the abutment of the pressure sleeve 337 against the components of the cut Christmas hanger and move forward with the material, facilitating the subsequent blanking operation.
[0030] Additionally, a limiting protrusion 344 is formed on the side wall of the mounting groove 342. A limiting groove 352 matching the limiting protrusion 344 is formed on the mounting ring 351. When the mounting ring 351 is placed in the mounting groove 342, the limiting protrusion 344 is retained in the limiting groove 352. The cooperation between the limiting protrusion 344 and the limiting groove 352 limits the rotation of the mounting ring 351 in the mounting groove 342, making the cutting knife 35 stable after installation and the second cutting knife 35 stable, thus guaranteeing the quality of cutting. At the same time, the cooperation between the limiting protrusion 344 and the limiting groove 352 also plays a positioning role in the operation of installing the cutting knife 35, ensuring the consistency of the positions of the cutting knives 35 after being installed on the second mounting plate 34, thereby facilitating the operation of installing the cutting knife 35.
[0031] Additionally, a plurality of blanking ejector rods 324 are fixedly connected to the driving plate 32 on one side of the cutting knife 35. A blanking opening 111 is formed on the supporting plate 11 below the blanking ejector rods 324. The components of the Christmas hanger retained on the material after cutting move forward with the material to above the blanking opening 111. While the driving plate 32 drives the cutting knife 35 to perform the next cutting operation, the blanking ejector rods 324 move downward with the driving plate 32 and push the components of the Christmas hanger retained on the material, ejecting the components of the Christmas hanger from the material and dropping them through the blanking opening 111, realizing the blanking of the components of the cut Christmas hanger, thereby saving the subsequent blanking operation and improving the production efficiency.
[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
