[0026] The utility model will be further described in detail through specific embodiments in combination with the drawings.

[0027] Example 1

[0028] As Figures 1-5 shown, the embodiment provides a cigarette machine M5 scraper adjusting device, which is installed on the rubbing drum 5 when in use, and is used for quickly adjusting the distance between the scraper 6 and the rubbing drum 5. Specifically, the cigarette machine M5 scraper adjusting device comprises a positioning plate 1, a connecting arm 2 and an adjusting plate 3, the connecting arm 2 is arranged at both ends of the positioning plate 1, and a U-shaped structure is formed together on the positioning plate 1, screw holes are arranged on the connecting arm 2, when in use, the connecting arm 2 is connected with the screw holes on the two end faces of the rubbing drum 5 through bolts, so as to install the entire adjusting device on the rubbing drum 5 and at the position corresponding to the scraper 6. The side of the positioning plate 1 close to the rubbing drum 5 is designed into a circular arc structure which is matched with the tobacco receiving groove 51 of the rubbing drum 5, and when in use, the entire tobacco receiving groove 51 is filled, and the other side is a flat surface for abutting against the scraper 6, the overall thickness of the positioning plate 1 is the gap between the scraper 6 and the tobacco receiving groove 51, and when the scraper 6 is adjusted, the scraper 6 only needs to be pushed to abut against the flat side of the positioning plate 1.

[0029] Further, in the actual adjustment process, the precision is relatively high, and the distance between the two ends of the scraper 6 and the inner side and the outer side of the rubbing drum 5 is not the same, which leads to poor rubbing of the product and wrinkling of the tipping paper, so a movable adjusting plate 3 is arranged on the side of the positioning plate 1 away from the tobacco receiving groove 51, the adjusting plate 3 serves as a support plate for the scraper 6, so that the scraper 6 is uniformly stressed, thereby ensuring that the distance between the two ends of the scraper 6 and the rubbing drum 5 is the same.

[0030] Specifically, two guide columns 4 are arranged on the positioning plate 1, the adjusting plate 3 is slidingly connected to the guide columns 4, and a cavity for accommodating the scraper 6 is arranged between the adjusting plate 3 and the positioning plate 1; the end of the guide column 4 away from the positioning plate 1 is provided with a screw thread, and a fixing block 42 (nut) is arranged on the screw thread; a spring 41 is arranged between the nut and the adjusting plate 3; the position of the fixing block 42 is adjustable, so as to adjust the rebound force of the spring 41. When the spring 41 is in a natural state, the distance between the positioning plate 1 and the adjusting plate 3 is slightly smaller than the width of the scraper 6; the rebound force of the spring 41 can be used to push the scraper 6 to be close to the planar side of the positioning plate 1, and finally the scraper 6 is clamped between the positioning plate 1 and the adjusting plate 3 under the rebound force of the spring 41; after clamping and fixing, the scraper 6 is fixed by using the adjusting bolt of the scraper 6; the scraper 6 is pushed and clamped by the spring 41, so that the scraper 6 does not need to be held, the fixing of the scraper 6 is facilitated, and the movement of the scraper 6 caused by tightening the adjusting bolt is avoided.

[0031] Specifically, the use process of the cigarette machine M5 scraper adjusting device is as follows:

[0032] The device is placed at the scraper 6, the adjusting plate 3 is pressed down, the spring 41 is compressed, and the scraper 6 is located between the positioning plate 1 and the adjusting plate 3; during the process, if the gap between the scraper 6 and the tobacco receiving groove 51 is greater than the standard value, a gap will be left between the scraper 6 and the positioning plate 1, and normal installation can be performed; if the gap between the scraper 6 and the tobacco receiving groove 51 is less than the standard value, the adjusting bolt of the scraper 6 is loosened, the scraper 6 is removed or moved down, the installation position of the positioning plate 1 is left, then the connecting arms 2 on both sides are connected to the rubbing drum 5 by using the bolt, after the device is installed and fixed, the scraper 6 is pushed up by the rebound of the spring 41, the end surface of the scraper 6 is abutted against the back plane of the positioning plate 1, and the scraper 6 is clamped by the positioning plate 1 and the adjusting plate, and finally the adjusting bolt of the scraper 6 is tightened, so that the gap between the scraper 6 and the tobacco receiving groove 51 can be quickly adjusted.

[0033] The above describes the present application by using specific examples, which is only used to help understand the present application and does not limit the present application. According to the idea of the present application, those skilled in the art can make some simple deductions, deformations or substitutions.
