AI Technical Summary
In existing sponge round cutters, the blades are difficult to disassemble, and the two ends of the sponge are difficult to align after being curled, resulting in difficulty in replacing the blades and uneven sponge curling.
By setting up a sliding assembly and a driving assembly, the blade can easily be removed from the blade by pushing the connecting rod to relax the blade by the blade; at the same time, the limit assembly limits the position of both ends of the sponge through the baffle and knob on the reel, making the two ends of the sponge relatively flat after reel.
It realizes convenient replacement of blades and alignment of both ends after sponge coiling, improving the efficiency of equipment and product quality.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] As the instruction manual Figure 1 , 2As shown, a circular cutter with replaceable blades includes a base 1, a cutting device 2, and a winding device 3. The cutting device 2 is arranged on the base 1, and the winding device 3 is fixedly arranged on one side of the base 1. The cutting device 2 cuts the sponge raw material, and the winding device 3 winds up the cut sponge.
[0028] As the instruction manual Figure 1 , 2 As shown in Figure 4, a pair of driving components 4 are fixedly arranged on both sides of the base 1, and the driving components 4 drive the cutting device 2 to move. The pair of driving components 4 include a protection frame 4.1 fixedly arranged on both sides of the base 1, a connecting rod 1 4.2 and a connecting rod 2 4.3 hinged to the protection frame 4.1, a connecting platform 4.4 fixedly arranged on the connecting rod 1 4.2 and the connecting rod 2 4.3, a first motor 4.5 fixedly arranged on the connecting platform 4.4, and a cutter wheel 4.6 fixedly arranged at one end of the output shaft of the first motor 4.5. The cutter wheel 4.6 is driven by the first motor 4.5. Since the blade is sleeved on the pair of cutter wheels 4.6, the cutter wheel 4.6 can drive the blade to rotate. The protection frame 4.1 is a hollow mechanism, and a boss 1 for the connecting rod 1 4.2 to be hinged is fixedly arranged at the bottom of the protection frame 4.1, and a boss 2 for the connecting rod 2 4.3 to be hinged is fixedly arranged at the bottom of the protection frame 4.1. The connecting rod 1 4.2 is fixedly passed through the connecting platform 4.4, and the connecting rod 1 4.2 is movable through the top of the protection frame 4.1. A handle is fixedly provided at one end of the connecting rod 1 4.2. The corresponding connecting rod 1 4.2 is moved by pushing the handle. Since one end of the connecting rod 1 4.2 is hinged to the inner bottom of the protection frame 4.1, the connecting rod 1 4.2 will swing around the hinge. One end of the connecting rod 2 4.3 is fixedly connected to the connecting platform 4.4, and the other end is hinged to the boss 2 at the inner bottom of the base 1, thereby assisting the connecting rod 1 4.2 to move the connecting platform 4.4.
[0029] As the instruction manual Figure 1 , 2As shown in Figure 3, a pair of connecting rods 4.2 are provided with a sliding assembly 5 at one end, and the sliding assembly 5 includes a sliding sleeve 5.1 provided on the connecting rod 4.2, a sliding member 5.2 rotatably connected to the sliding sleeve 5.1, and a pair of guide rails 5.3 passing through the sliding member 5.2. Each guide rail 5.3 is provided with a thread, and each guide rail 5.3 is threadedly connected to a pair of nuts. A pair of nuts are respectively provided on both sides of the sliding member 5.2, and the position of the sliding member 5.2 is rotated by a pair of nuts. A pair of connecting shafts are provided on both sides of the sliding sleeve 5.1, a pair of bosses 3 are provided on the sliding member 5.2, and a pair of connecting shafts are rotatably connected to the corresponding bosses 3, and the sliding member 5.2 is slidably provided on the protection frame 4.1, and a slide bar is provided on both sides of the sliding member 5.2, and a slide groove for the sliding member 5.2 to slide is provided at the top of the protection frame 4.1. The sliding member 5.2 slides on the protection frame 4.1 through the slide bars on both sides, and at this time, the sliding member 5.2 does not contact the pair of guide rails 5.3. The winding device 3 is provided with a limit assembly 6, which limits the width of the winding sponge. The limit assembly 6 includes a pair of baffles 6.1 slidably arranged on the winding device 3, and a knob 6.2 is threadedly rotatably connected to each of the pair of baffles 6.1, and the knob 6.2 is threadedly rotatably passed through one side of the baffle 6.1. The pair of baffles 6.1 are slidably arranged on the winding shaft, and the position of the baffle 6.1 on the winding shaft is fixed by abutting one end of the knob 6.2 against the winding shaft.
[0030] The working principle of this utility model:
[0031] When the blade needs to be replaced, first adjust one of the sliding components 5, and rotate the nuts on the pair of guide rails 5.3 respectively, so that they rotate to both sides of the slide slot, and no longer restrict the slide 5.2. Then use the handle to push the connecting rod 1 4.2 toward the center of the base 1. Since the bottom of the connecting rod 1 4.2 is hinged with the protection frame 4.1, the connecting rod 1 4.2 will swing along the hinge. Since the sliding sleeve 5.1 is arranged on the connecting rod 1 4.2, the sliding sleeve 5.1 will move upward along the connecting rod 1 4.2. Since the sliding sleeve 5.1 is rotationally connected to the slide 5.2 through the connecting shafts on both sides, it will drive the slide 5.2 to move to one side along the slide slot. Since the connecting rod 1 4.2 is fixedly connected to the connecting platform 4.4, and the connecting platform 4.4 is fixedly provided with the first motor 4.5, and the output shaft of the first motor 4.5 is fixedly provided with a cutter wheel 4.6, the connecting rod 1 4.2 will drive the cutter wheel 4.6 to move to the side close to the base 1, and repeat the above. Step 1: adjust the other sliding component 5. Since the two cutting wheels 4.6 are moving toward the center, the cutting wheel 4.6 no longer restricts the blade wrapped thereon. Then, you only need to remove the blade, and then put a new blade on a pair of cutting wheels 4.6. Then, push the connecting rod 4.2 so that the connecting rod 4.2 drives the cutting wheel 4.6 to move until the blade is stably wrapped around the two cutting wheels 4.6. Turn the corresponding nuts so that each pair of nuts abuts against the two sides of the sliding member 5.2 respectively, thereby limiting the position of the sliding member 5.2, fixing the position of the cutting wheel 4.6, and completing the blade change.
[0032] When the winding device 3 winds up the sponge, first adjust the distance between the pair of baffles 6.1 so that the distance between the pair of baffles 6.1 is exactly equal to the width of the sponge. At this time, rotate the corresponding knob 6.2. Since the knob 6.2 thread rotates through one side of the baffle 6.1, rotate the knob 6.2 to make it abut against the winding shaft that passes through the baffle 6.1, thereby fixing the position of the baffle 6.1 on the winding shaft. When winding, the sponge will always be located between the two baffles 6.1, so that the two ends of the rolled sponge are relatively neat.
[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
