[0002] In the tobacco industry, the shredder is a key piece of equipment in tobacco production. The blade assembly of the EVO shredder has high installation accuracy requirements. Currently, the parallelism and gap of each component are located manually by taking multiple measurements at multiple points. Manual measurement is time-consuming and prone to measurement errors.

[0003] When the blade assembly is installed on the base, there may be non-standard parallelism and gap. When the guide strip and the two blade covers are not level or the gap is too small, when the drive motor drives the guide strip to reciprocate, the guide strip is prone to friction with the blade covers on both sides, causing obstruction, wear, jamming and other phenomena, which affect the continuous operation of the shredder and also cause wear or even damage to the parts of the shredder.

[0004] Therefore, there is an urgent need for a positioning fixture for the gap of the blade assembly of the shredder to solve the above problems. Utility Model Content

[0036] like Figures 1-4As shown, in this embodiment, the blade assembly gap positioning fixture of the shredder is used to position the blade assembly. The blade assembly includes a base 100, a guide strip 200, and two blade covers 300. The two blade covers 300 are mounted on the base 100, and the guide strip 200 is slidably disposed between the two blade covers 300. The blade assembly gap positioning fixture of the shredder includes a main body 1 and two positioning components. The two positioning components are respectively located at both ends of the guide strip 200. Each positioning component includes a positioning part 2 and two insertion parts 3. The positioning part 2 is disposed on the main body 1 and is sandwiched between the two blade covers 300 to position the two blade covers 300 to be parallel to each other. The two insertion parts 3 are parallel and spaced apart from the positioning part 2, and the two insertion parts 3 can be respectively inserted into the two sides of the guide strip 200 and the corresponding blade cover 300.

[0037] Specifically, two blade cover 300s are installed on the base 100. The two blade cover 300s are parallel and have a certain distance between them. A guide wire 200 is located in the gap between the two blade cover 300s. The guide wire 200 has sliding grooves on both sides. The sides of the two blade cover 300s are respectively located in the corresponding sliding grooves. The guide wire 200 slides with the blade cover 300 through the sliding grooves. Two positioning components are respectively protruding from both ends of the main body 1 on the same side. Two insertion parts 3 are spaced apart and protruding from the positioning parts 2. The main body 1 presses against one of the blade cover 300s. The positioning parts 2 of the two positioning components are spaced apart between the two blade cover 300s. That is, the sides of the two blade cover 300s are respectively in contact with the two end faces of the positioning parts 2, so that the distance between the two blade cover 300s is equal to the width of the positioning parts 2 and they are parallel to each other. This allows for precise positioning of the parallelism and distance between the two blade cover 300s, with a required distance of 32mm. The two positioning components have their insertion parts 3 facing each other and spaced apart. The two insertion parts 3 of the same positioning component are respectively inserted between the two sides of the guide strip 200 and the blade cover 300, i.e., the insertion parts 3 are inserted into the groove. The two end faces of the insertion parts 3 are respectively in contact with the bottom of the groove and the side of the blade cover 300, ensuring that the gap between the two blade covers 300 and the guide strip 200 is equal to the thickness of the insertion part 3 and that all three are parallel to each other. This allows for precise positioning of the parallelism and gap between the two blade covers 300 and the guide strip 200, requiring a gap of 0.8mm. This blade assembly gap positioning fixture for the shredder can accurately position the blade assembly, enabling standardized installation, ease of use, and ensuring smooth operation of the blade assembly, preventing jamming and obstruction, thereby reducing wear on the blade assembly.

[0038] Furthermore, continue to refer to Figures 1-4The positioning part 2 has a first positioning surface 21 and a second positioning surface 22, which are respectively abutted against the sides of the two blade cover 300. The main body 1 has a third positioning surface 11, which is perpendicular to the second positioning surface 22 and abutted against the end face of the blade cover 300. Specifically, the main body 1 presses against one of the blade cover 300, the third positioning surface 11 abuts against the end face of the blade cover 300, and then the sides of the two blade cover 300 are respectively abutted against the first positioning surface 21 and the second positioning surface 2 of the positioning part 2, so that the distance between the two blade cover 300 is equal to the distance between the first positioning surface 21 and the second positioning surface 22 and they are parallel to each other, thereby accurately positioning the parallelism and distance between the blade cover 300.

[0039] Furthermore, continue to refer to Figures 1-4 The insertion part 3 has a fourth positioning surface 31 and a fifth positioning surface 32. The guide wire 200 has a sliding groove. The fourth positioning surface 31 slides against the bottom of the sliding groove, and the fifth positioning surface 32 slides against the side of the blade cover 300. Specifically, the fourth positioning surface 31 and the fifth positioning surface 32 are both arranged parallel to the second positioning surface 22. The two insertion parts 3 of the same positioning component are respectively inserted between the two sides of the guide wire 200 and the blade cover 300, that is, the insertion part 3 is inserted into the sliding groove. The fourth positioning surface 31 and the fifth positioning surface 32 of the insertion part 3 are respectively against the bottom of the sliding groove and the side of the blade cover 300, so that the gap between the two blade covers 300 and the guide wire 200 is equal to the distance between the fourth positioning surface 31 and the fifth positioning surface 32 and the three are parallel to each other, thereby accurately positioning the parallelism and gap between the two blade covers 300 and the guide wire 200.

[0040] Furthermore, continue to refer to Figures 1-4 The slicing machine blade assembly gap positioning fixture also includes a limiting part 4, which is spaced apart from the positioning part 2 on the main body 1, and is parallel to the second positioning surface 22. Specifically, the limiting part 4, the third positioning surface 11, and the second positioning surface 22 form a concave structure. The blade cover 300 is a standard part, that is, the width of the blade cover 300 is equal to the distance between the limiting part 4 and the second positioning surface 22, so that the two sides of the blade cover 300 can fit against the second positioning surface 22 and the limiting part 4 respectively, and the positioning is accurate.

[0041] Furthermore, continue to refer to Figures 1-4The main body 1 is provided with a clearance part 5. The guide wire 200 is mounted on the base 100 via a motor 400. The clearance part 5 is used to prevent the motor 400 from sliding relative to the blade cover 300. Specifically, the clearance part 5 has a U-shaped structure and a sixth positioning surface 51. The sixth positioning surface 51 is arranged parallel to the second positioning surface 22. The sixth positioning surface 51 is used for parallel positioning with the guide wire 200. Under the driving action of the motor 400, during the reciprocating sliding process of the guide wire 200 relative to the blade cover 300, the distance between the guide wire 200 and the sixth positioning surface 51 is measured to ensure that the measured distance value remains constant. Thus, the parallelism between the guide wire 200 and the two blade covers 300 can be further verified and accurately positioned through the sixth positioning surface 51.
