The soap particle extruding device can cut the soap particles in time during the extruding process, thereby reducing the intermediate slitting time, keeping the soap particles soft during rolling and improving the plasticity and quality of the soap.

[0004] However, when the above-mentioned device cuts the soap particles, the soap particles are in paste form during cutting, and the adhesive properties of the soap particles cause them to easily adhere to the blade and the rotating shaft.

The soap particles have a certain hardness when being cooled and cut, and the granulating behavior needs to be repeated frequently, which causes the blade edge to be worn, greatly shortening the service life of the blade. Once the blade is severely worn, it needs to be stopped for maintenance and replacement.

[0030] With reference to Figure 1 A U-shaped frame 8 is fixedly arranged on the collecting box 43, a sliding groove is arranged on the side wall of the extrusion chamber 4, a sliding rod 82 is slidably arranged in the sliding groove, a mounting disc 81 is fixedly arranged at one end of the sliding rod 82 away from the extrusion chamber 4, and a plurality of ejector pins matched with the extrusion opening are fixedly arranged on the mounting disc 81; the cleaning of the extrusion opening is realized through the rotating mounting disc 81 and the ejector pins moving along the sliding rod 82, the soap particle material not completely extruded after cutting is effectively avoided from being accumulated in the extrusion opening and causing blockage, the cleaning efficiency of the equipment is improved, and the service life of the equipment is prolonged.

[0031] With reference to Figure 2 A semicircular plate 9 is fixedly arranged at the end of the cutting blade 42, and a baffle 91 is fixedly arranged at one end of the side wall of the cutting blade 42 away from the blade edge; the semicircular plate 9 can make the separation of the grinding stone 411 and the blade edge more smooth, and the baffle 91 can ensure that the soap particles generated by cutting fall into the collecting box 43.

[0032] The specific working principle of the utility model is as follows:

[0033] In use, the driving motor 41 is started to drive the cutting knife 42 to rotate and cut the soap block extruded through the extrusion opening into soap particles. Since the driving motor 41 and the rotating shaft of the cutting knife 42 are arranged at the side of the extrusion chamber 4, the rotating shaft is ensured not to contact the extruded soap particles, and thus the cutting process is not affected by the adhesion of the raw materials. After the cutting knife 42 cuts the soap particles, the soap particles can be knocked off by the baffle 91 and fall into the collecting box 43, which can reduce the adhesion of the soap particles to the blade and inhibit the inconvenience of collecting the soap particles flying to both sides after being cut. When the cutting knife 42 rotates to the horizontal position outside the extrusion chamber 4, the grinding stone 411 can be contacted. The cutting knife 42 continues to rotate under the driving of the driving motor 41, and thus the mounting rod 47 moves. Since the mounting rod 47 can only vertically slide in the sliding sleeve 45, the mounting rod 47 drives the mounting block 410 and the grinding stone 411 to gradually slide along the blade from the position close to the rotating shaft to the end of the blade when the cutting knife 42 rotates. In this process, the grinding stone 411 can always maintain a certain pressure on the blade under the tension of the spring 49, and thus the grinding effect on the blade is ensured. When rotating to the end, the cutting knife 42 can be separated from the grinding stone 411 under the auxiliary action of the semicircular plate 9 and through the corresponding position of the sliding sleeve 45. The mounting rod 47 is reset under the action of the spring 49, and the next blade can be ground. The cutting and grinding of the blade can be realized at the same time, the blade of the cutting knife 42 is ensured to be sharp at all times, and thus the cutting efficiency is ensured and improved.

[0034] When the blade contacts the grinding stone 411, the mounting block 410 is first pressed to slide upward along the mounting groove, and thus the two side gears 51 are driven to rotate by the upward movement of the double-sided rack 5, and thus the driven rack 52 moves downward to drive the driving arm 53 to move downward. Under the action of the inclined surface, the two mounting plates 54 are pressed to move inward, and the cleaning sponge 6 clamps the blade. The cleaning sponge 6 can clean the soap particles and raw materials attached to the blade, ensure the cleanliness of the blade, and thus ensure the cutting effect. After the blade passes, the mounting block 410 and the mounting plate 54 can be automatically reset under the action of the spring 58 and the spring 57.

[0035] Each time the blade is ground, the mounting rod 47 drives the sliding block 46 to slide along the sliding groove of the sliding sleeve 45 to the top, so as to press the guide plate 7. When the mounting rod 47 is reset by the spring 49, the guide plate 7 is reset under the action of the spring 71, and thus the piston rod 72 can make a suction movement in the sealing cylinder. A small amount of liquid is sucked from the water tank 74 to the indicating box 73 through the one-way valve pipe, so as to roughly count the grinding times. When the liquid accumulates to the warning position of the indicating window 75, the operator can be warned that the grinding stone 411 has reached the service life, the grinding effect on the blade is poor, and the grinding stone 411 can be replaced in time. The working principle and connection mode of the one-way valve are both mature technologies, and thus will not be described in detail again.

[0036] When the cutting is completed, the granule material which is not completely extruded will be accumulated in the extrusion port, at this time, the cutting knife 42 can be staggered with the extrusion port, and the mounting disc 81 is rotated along the slide rod 82 to the corresponding position of the extrusion port, the mounting disc 81 is pushed in along the slide rod 82, the extrusion port is cleaned through the thimble, then the mounting disc 81 can be re-erected on the U-shaped frame 8 through reverse operation, so that the equipment cleaning can be ensured, the soap granule material hardening caused by the extrusion port is avoided to cause blockage, and the normal cutting work is not affected when the cutting knife 42 works.

[0037] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
