[0037] Example

[0038] like Figure 1-4 As shown, the utility model provides a cleaning mechanism for a nylon 6 raw material melting device, comprising: a rotating motor 1, a rotating block 2, and a telescopic mechanism 3. The rotating block 2 is arranged on the output shaft of the rotating motor 1. Two groups of through holes 20 are horizontally arranged on the rotating block 2. The telescopic mechanism 3 is arranged on opposite sides of the rotating block 2. The telescopic mechanism 3 comprises: a moving block 30, a limiting rope 31, and a spring 32. A scraper assembly 4 is arranged on the bottom surface of the moving block 30. One end of the limiting rope 31 is fixed to a side of the moving block 30 close to the rotating block 2, and the other end passes through a group of through holes 20 and a limiting block 310 is fixed at the end. The spring 32 is sleeved on the outer surface of the limiting rope 31. One end of the spring 32 is fixed to the moving block 30, and the other end is fixed to the rotating block 2. In the initial state, the limiting rope 31 in the spring 32 is in a straightened state, and the limiting block 310 contacts the side wall of the rotating block 2. The limiting rope 31 is made of soft material. Figure 1 The device is shown in the initial state. When the device is to be inserted into a heating barrel with melted nylon 6 raw material, the telescopic mechanism 3 is manually compressed so that the moving blocks 30 of the two sets of telescopic mechanisms 3 are close to each other, and the spring 32 is in a compressed state, so that the device is reduced in width to better enter the heating barrel. After the device enters the heating barrel, the spring 32 rebounds so that the scraper assembly 4 contacts the inner wall of the heating barrel. When the device needs to be retracted from the heating barrel, the limiting block 310 is manually pulled out from the upper part of the heating barrel, and the limiting rope 31 drives the spring 32 to compress. Since the limiting rope 31 is made of soft material, the limiting rope 31 can turn freely.

[0039] In this embodiment, the limiting rope 31 is preferably made of nylon rope.

[0040] In this embodiment, the scraper assembly 4 includes: a fixed tube 40, an upper scraper 41, a mobile tube 42, and a lower scraper 43. The upper end of the fixed tube 40 is fixed to the bottom surface of the mobile block 30. An annular baffle 400 is provided at the mouth of the fixed tube 40. A slot 401 is provided on the baffle 400. The upper end of the upper scraper 41 is connected to the outer surface of the fixed tube 40. The mobile tube 42 extends a limiting column 420 upward from the bottom. The limiting column 420 is limited in the slot 401. Part of the fixed tube 40 can enter the mobile tube 42. The lower end of the lower scraper 43 is connected to the outer surface of the mobile tube 42. The rotation of the scraper assembly 4 can drive the upper scraper 41 and the lower scraper 43 to contact the inner wall of the heating barrel. The upper scraper 41 and the lower scraper 43 are in different vertical planes. The scraper assembly 4 can produce expansion and contraction in the vertical direction, and can have higher adaptability to heating barrels of different depths. It is preferred to provide a rubber pad 44 at the lower end of the moving tube 42. The provision of the rubber pad 44 can reduce the wear of the scraper assembly 4 on the bottom surface of the heating barrel.

[0041] In this embodiment, it also includes: a shelf plate 5, a connecting shaft is arranged on the top of the rotating block 2, the connecting shaft is connected to the rotating motor 1 through a coupling, a connecting hole is arranged on the shelf plate 5, a bearing is arranged in the connecting hole, and the bearing is arranged on the outer surface of the connecting shaft. The shelf plate 5 enables the device to be placed on the heating barrel.

[0042] In this embodiment, the height of the lower scraper 43 is the same as the height of the movable tube 42, and the height of the upper scraper 41 is the same as the height of the fixed tube 40. The combination of the upper scraper 41 and the lower scraper 43 can better clean the inner wall of the heating barrel.

[0043] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
