[0002] Polylaurolactam belongs to thermoplastics, which are the most widely used plastics. They are made of thermoplastic resin as the main component and various additives. Under certain temperature conditions, plastics can soften or melt into any shape, and the shape remains unchanged after cooling; this state can be repeated many times and always has plasticity, and this repetition is just a physical change. This kind of plastic is called thermoplastic.

[0003] Under the existing technology, a device that drives a motor to rotate a spiral cutter is used to crush and granulate polylaurolactam. However, when the existing device crushes and granulates polylaurolactam, the material may be carbonized due to local overheating of the cutter, and the material may have a large size difference after crushing and granulating. The problem addressed by this device is how to prevent the polylaurolactam material from being carbonized during crushing and granulating and solve the problem of large size difference after crushing and granulating.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides the following technical solutions: a crushing and granulating device for polylaurolactam material, comprising a main body barrel 1, a feed box 2 is fixedly installed on the left side of the top of the main body barrel 1, a driving motor 5 is fixedly installed in the middle of the top of the main body barrel 1, and a spiral blade 20 and a spiral cutter 23 are fixedly installed on the driving motor 5 through a rotating shaft 19 at the output end, a baffle 22 is fixedly installed inside the main body barrel 1, a drop opening 21 is opened on the surface of the baffle 22, a granulating disk 24 is fixedly installed at the bottom of the main body barrel 1, a granulating opening 25 is opened on the surface of the granulating disk 24, and the spiral cutter 23 is arranged between the baffle 22 and the granulating disk 24, water tanks 6 are fixedly installed on both sides of the front and rear of the main body barrel 1, a water pipe 7 is fixedly installed at the bottom of the water tank 6, a water-cooled radiator 8 is fixedly installed on the surface of the main body barrel 1, and the radiator 8 is fixedly connected to one end of the water pipe 7, a storage box 27 is fixedly installed at the bottom of the main body barrel 1, a table board 14 is fixedly installed at the bottom of the storage box 27, and a connecting pipe 12 is fixedly installed on the surface of the water tank 6.

[0021] The starting drive motor 5 can drive the spiral blade 20 and the spiral cutter 23 to rotate through the rotating shaft 19 at the output end. The rotation of the spiral blade 20 can continuously stir the polylaurolactam material in the main barrel 1, so that the material falls from the drop opening 21 on the surface of the baffle 22 to the bottom. The rotation of the spiral cutter 23 makes the material crushed and granulated, and falls into the storage drawer 13 inside the storage box 27 below through the granulation opening 25 on the granulation disk 24, that is, the crushing and granulation of the material is completed. The larger material in the storage drawer 13 can be crushed and granulated again, which greatly solves the problem of large size differences of polylaurolactam materials after granulation, can ensure material quality, and increase the practicality of the device. Water is injected into the water tank 6 through the water inlet 11, so that the water tank 6, the water pipe 7, the water cooling radiator 8 and the connecting pipe 12 work in a cycle. During the operation of the device, the water cooling radiator 8 reduces the temperature of the rotating shaft 19 and the spiral cutter 23 by reducing the barrel temperature, thereby preventing the polylaurolactam material from being crushed. The carbonization problem caused by overheating of the rotating shaft and the spiral cutter during the granulation process ensures the quality of the material after crushing and granulation. The setting of the box cover 3 and the movable handle 4 makes it easy to cover the feed box 2 at any time to prevent dust and impurities from entering. The setting of the storage drawer 13 and the second fixed handle 26 makes it easy to check and store the crushed and granulated polylaurolactam material. The setting of the first fixed handle 17 makes it easy to better grasp and carry the device, and the multiple anti-slip grooves 18 are arranged in a circle on the surface of the first fixed handle 17, which can increase the friction on the surface of the first fixed handle 17, so that the user is not likely to slip when grasping the first fixed handle 17. The setting of the four supporting legs 15 is easy to stabilize the device, and the setting of the four fixed pads 16 increases the friction with the ground, making the device more stable. The setting of the water inlet 11 makes it easy to inject water into the water tank 6 at any time. The setting of the water outlet pipe 9 and the valve 10 makes the water tank and the water-cooled radiator drain better. All electrical equipment in this device is powered by an external power supply.

[0022] In one aspect of the present embodiment, the provision of the box cover 3 and the movable handle 4 makes it convenient to cover the feed box 2 at any time to prevent dust and impurities from entering, thereby ensuring that the polylaurolactam material is clean and free of impurities. The provision of the storage drawer 13 and the second fixed handle 26 facilitates the inspection and storage of the crushed and granulated polylaurolactam material. If problems are found in the crushing and granulation, the crushing and granulation operation can be performed again, and it can be stored and used if there are no problems.

[0023] In one aspect of the present embodiment, the provision of the first fixed handle 17 facilitates better grasping and carrying of the device, and the plurality of anti-slip grooves 18 are arranged circumferentially on the surface of the first fixed handle 17, which can increase the friction on the surface of the first fixed handle 17, making it less likely for the user to slip when grasping the first fixed handle 17. The provision of four supporting legs 15 facilitates stabilizing the device, and the provision of four fixed pads 16 increases the friction with the ground, making the device more stable.

[0024] In one aspect of the present embodiment, the setting of the water inlet 11 makes it convenient to inject water into the water tank 6 at any time, and the top thread of the water inlet 11 is provided with a sealing cover, which facilitates better sealing of the water tank and avoids the problem of impurities entering the water tank and making it difficult to clean. The setting of the water outlet pipe 9 and the valve 10 allows better drainage of the water tank and the water-cooled radiator, greatly increasing the practicality of the device and improving the working efficiency of the device.

[0025] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
