[0031] In order to make the purpose, technical scheme and advantages of the utility model clearer, the embodiments of the utility model will be further described in detail below with reference to the drawings.

[0032] The embodiments of the utility model provide a cutter positioning device for positioning a cutter 1 at a preset mounting position on a gear shaft 2, referring to Figure 1 , the gear shaft 2 is arranged in a case 3, the cutter 1 is arranged on a cutter seat 4, the cutter seat 4 is sleeved on the gear shaft 2, the gear shaft 2 extends along a first direction (X direction in Figure 1 and Figure 2 ,

[0033] The positioning device is detachably connected with the case 3, two oppositely arranged positioning surfaces 6 are arranged on the positioning device, both of the two positioning surfaces 6 are perpendicular to the first direction, the cutter seat 4 has two end surfaces 7 perpendicular to the first direction, the distance between the two positioning surfaces 6 is equal to the distance between the two end surfaces 7 of the cutter seat 4, and the cutter seat 4 can be at least partially inserted between the two positioning surfaces 6, so that the two positioning surfaces 6 are respectively attached to the two end surfaces 7 of the cutter seat 4. The positioning device can be fixed at a specific position on the case 3 (i.e. the position where the positioning device is located in Figure 1 ), and the positioning device can define the mounting position of the cutter seat 4 by using the two positioning surfaces 6. When the positioning device is located at the specific position, the cutter 1 inserted between the two positioning surfaces 6 is located at the preset mounting position (i.e. the position where the cutter 1 is located in Figure 1 ).

[0034] By adopting the above technical solution, two opposing positioning surfaces 6 are set on the positioning device, and the distance between the two positioning surfaces 6 is equal to the thickness of the blade holder 4, so that the blade holder 4 can be accommodated between the two positioning surfaces 6, thereby limiting the relative position between the cutter 1 and the positioning device. When the positioning device is fixed at a specific position on the housing 3, the cutter 1 is located in the preset installation position, and the positioning surfaces 6 can restrict the axial movement of the cutter 1 and the blade holder 4 along the gear shaft 2, thereby preventing the operator from fixing the blade holder 4 to the gear shaft 2, ensuring that the cutter 1 is always located in the preset installation position, and thus ensuring that the crease line cut by the cutter 1 is located in the preset position. Specifically, when installing the cutter 1, first fix the cutter 1 on the cutter holder 4 and then fit the cutter holder 4 onto the gear shaft 2; then insert the cutter holder 4 into the gap between the two positioning surfaces 6, so that the two positioning surfaces 6 respectively fit against the two end faces 7 of the cutter holder 4; then fix the positioning device at a specific position on the housing 3, and the positioning device restricts the degree of freedom of the cutter holder 4 in the first direction, so that the cutter holder 4 is located in the preset installation position.

[0035] Furthermore, the positioning device includes a fixed base 5 and a sliding member 9. The fixed base 5 is detachably connected to the housing 3 to fix the positioning device in a specific position. The sliding member 9 is disposed on the fixed base 5 and is movable relative to the fixed base 5 along... Figure 1 The Y-direction shown slides between the first position 10 and the second position 12. The slider 9 has a slot 16, and the two positioning surfaces 6 are the two opposing inner sidewalls of the slot 16. When the slider 9 slides to the first position 10, as... Figure 1 As shown, the slot 16 is inserted into the outside of the blade holder 4, so that the two positioning surfaces 6 respectively fit against the two end faces 7 of the blade holder 4 to define the installation position of the blade holder 4, so that the cutter 1 on the blade holder 4 is located in the preset installation position; when the slider 9 slides to the second position 12, the slot 16 separates from the blade holder 4 to prevent the slot 16 from interfering with the movement of the blade holder 4 along the first direction to the installation position of the blade holder 4. In this embodiment, when installing the cutter 1, the cutter 1 is first installed on the blade holder 4, the blade holder 4 is sleeved on the gear shaft 2, and the gear shaft 2 is installed inside the chassis; then the slider 9 is slid to the second position 12 to prevent the slider 9 from interfering with the blade holder 4 when the fixing seat 5 is installed later; then the fixing seat 5 is installed in a specific position on the chassis 3; the slider 9 is moved toward the first position 10, and at the same time the blade holder 4 is moved along the first direction so that the blade holder 4 is inserted into the slot 16, thus limiting the blade holder 4 to the preset installation position. Additionally, the tool holder 4 is provided with a threaded hole 15. After the tool holder 4 is positioned in the preset installation position, tightening the bolt inside the threaded hole 15 can fix the tool holder 4 onto the gear shaft 2. After installation, the sliding member 9 can be moved to the second position 12, and the fixing seat 5 can be removed from the housing 3.

[0036] Furthermore, the mounting base 5 includes a crossbeam 11 and a positioning rod 8. The crossbeam 11 extends along a first direction and is detachably connected to the chassis 3, specifically by bolts. When installing the cutter 1, the crossbeam 11 is connected to the chassis 3; after installation, the crossbeam 11 is removed from the chassis 3. The positioning rod 8 is located on the crossbeam 11, and its length direction (…) Figure 1 and Figure 2 The first position 10 and the second position 12 are located on the positioning rod 8, and the sliding member 9 is sleeved on the positioning rod 8 and can slide along the Y direction.

[0037] Furthermore, such as Figure 2 As shown, the positioning rod 8 has a rectangular cross-section, and the sliding member 9 has a rectangular through hole 21. The rectangular through hole 21 is fitted onto the positioning rod 8, and the sliding member 9 can slide along the positioning rod 8 under the action of external force. The rectangular through hole 21 and the rectangular cross-section positioning rod 8 cooperate to prevent the sliding member 9 from rotating around the positioning rod 8, so as to keep the positioning surface 6 always perpendicular to the first direction, which facilitates the positioning surface 6 to fit with the end face 7 of the tool holder 4.

[0038] Furthermore, such as Figure 1 As shown, the chassis 3 is provided with a clearance opening 14, which faces the preset installation position. The positioning rod 8 can pass through the clearance opening 14 and enter the interior of the chassis 3. Two threaded holes 15 are provided on each side of the clearance opening 14, and two connecting holes 13 corresponding to the two threaded holes 15 are provided at both ends of the crossbeam 11. The connecting holes 13 are connected to the threaded holes 15 by bolts. The clearance opening 14 can be an inherent opening on the chassis 3 in the prior art, or it can be an opening machined by the operator on the chassis 3. After installation, the operator can choose to seal or open the clearance opening 14 as needed.

[0039] Furthermore, such as Figure 1 As shown, the blade holder 4 is disc-shaped, and the cutter 1 protrudes from the outer circumference of the blade holder 4. The cutter 1 includes crescent blades 17 and dotted blades 18 arranged alternately along the circumference of the blade holder 4, and a positioning notch 19 is provided between the crescent blades 17 and the dotted blades 18.

[0040] Furthermore, such as Figure 1 As shown, each slot 16 is provided with a mounting surface 22. The mounting surface 22 is located between two positioning surfaces 6 and is perpendicular to the two positioning surfaces 6 respectively. The mounting surface 22 is provided with a positioning piece 20 protruding from the mounting surface 22, and the edge of the positioning piece 20 faces the outer circumferential surface of the blade holder 4. When the sliding member 9 moves to the first position 10, the positioning piece 20 can be inserted into its corresponding positioning notch 19 to restrict the cutter 1 from rotating around its circumference.

[0041] The number of the cutting knives 1 in the present fact example is two, accordingly, the number of the knife holders 4, the sliding pieces 9 and the positioning rods 8 is also two, and each positioning rod 8, sliding piece 9, knife holder 4 and cutting knife 1 corresponds one to one. When installing the cutting knife 1, rotating the two knife holders 4 around the gear shaft 2, and inserting the positioning pieces 20 on the two sliding pieces 9 into the positioning notches 19 on the two cutting knives 1 respectively, the positions of the two cutting knives 1 on the circumferences of the knife holders 4 can be limited to be consistent, and the two cutting knives 1 can cut the consistent and symmetrical crease lines on the inner frame paper.

[0042] The embodiment of the present application also provides an inner frame paper processing device.

[0043] The embodiment of the present application also provides a packaging machine, which comprises the inner frame paper processing device.
