The embodiments of the present utility model are described in detail below in conjunction with the drawings.

[0037] It should be understood that the drawings are only used to illustrate the present application.

[0038] A pneumatic slitting knife with adjustable deflection angle, such as Figure 1-Figure 17 As shown, it includes a tool body fixing seat 1, a main rod 2 rotatably arranged on the tool body fixing seat 1, a fixing block 3 connected to the main rod 2, a tool assembly 4 connected to the fixing block 3, and a feed adjustment handle 21 arranged at the tail of the main rod 2.

[0039] The tool assembly 4 includes a tool fixing shell connected to the fixing block 3, a knife-supporting cylinder arranged on the tool fixing shell, a circular knife arranged on the knife-supporting cylinder, and a tool protection cover arranged on the outside of the circular knife. One side of the tool protection cover is open for easy cutting. The bottom of the circular knife extends below the bottom of the tool protection cover, and the remaining part of the circular knife is protected by the tool protection cover to avoid scratching the operator.

[0040] The side of the tool fixing shell close to the fixing block 3 is set to a dovetail shape, and the side of the fixing block 3 close to the tool fixing shell is provided with a dovetail groove 31, and the dovetail-shaped tool fixing shell is inserted into the dovetail groove 31 to realize the splicing of the tool fixing shell and the fixing block 3. The dovetail splicing makes the connection more reliable and easy to disassemble.

[0041] An adjustment hole 32 is provided on one side of the fixing block 3 away from the dovetail groove 31, and an adjustment rod 5 is inserted into the adjustment hole 32. By rotating the adjustment rod 5, the connection between the adjustment rod 5 and the adjustment hole 32 includes a limiting posture and an adjustment posture, such as Figure 2 As shown, in the restricted posture, the tool assembly 4 is in a normal position, as shown in FIG. Figure 3 As shown, when adjusting the posture, the tool assembly 4 is in an adjustable state, and the position of the tool assembly 4 is adjusted leftward or rightward according to actual needs to adapt to cutting needs. In order to prevent the unreliable connection between the adjustment rod 5 and the adjustment hole 32, a connecting assembly is provided after the adjustment rod 5 is inserted into the adjustment hole 32 to connect them. The connecting assembly includes two connecting bolts, and the two connecting bolts reliably connect the adjustment rod 5 and the adjustment hole 32.

[0042] The adjusting rod 5 includes a connecting section connected to the blade fixing seat 1 and an adjusting section connected to the fixing block 3. The connecting section is set as a circular rod, and the adjusting section is set as a shape that matches the adjusting hole 32. Of course, the adjusting rod 5 can be set as a whole to a shape that matches the adjusting hole 32. The specific setting method can be set as needed. In this solution, the connecting section is set as a circular rod for easy rotation. The two sides of the adjusting section are set as planes, and the two ends of the adjusting section are set as arc surfaces. The straight-line distance between the two planes is less than the straight-line distance between the two arc surfaces. Of course, the adjusting section can set both side surfaces and both end surfaces as planes, as long as the relative distances are not equal. The adjustment hole 32 includes a limiting direction and a moving direction. The limiting direction is the same as the axial direction of the connecting bolt. When the two arc surfaces are set in the limiting direction, the straight-line distance between the two arc surfaces is equal to the distance in the limiting direction of the adjusting hole 32, and the adjusting rod 5 cannot move left and right. When the two arc surfaces are set in the moving direction, the straight-line distance between the two planes is less than the distance in the limiting direction of the adjusting hole 32, and the adjusting rod 5 can move left and right. The left and right deflection angles of the tool assembly 4 can be adjusted by adjusting the screw-in length of the two connecting bolts.

[0043] Mounting holes 33 are provided on both sides of the fixing block 3. The mounting holes 33 are connected to the adjusting holes 32. The axial direction of the mounting holes 33 is the same as the limiting direction of the adjusting holes. Abutment holes 51 are provided around the adjusting rod 5. When the position of the adjusting rod 5 needs to be limited, the two connecting bolts pass through the mounting holes 33 and abut against the adjusting rod 5. The abutment holes 51 include positioning abutment holes provided on two arc surfaces and moving abutment holes provided on a plane. When the tool assembly 4 is in a normal working state, the two positioning abutment holes are aligned with the two mounting holes 33. The two connecting bolts pass through the mounting holes 33 and abut against the positioning abutment holes to connect the adjusting rod 5 to the fixing block 3. That is, the two connecting bolts abut against the adjusting rod 5 in the limiting direction of the adjusting hole 32, and the adjusting rod 5 cannot be displaced. When the tool needs to be adjusted left and right, the two movable abutment holes are aligned with the two mounting holes 33, and the two connecting bolts pass through the mounting holes 33 and abut against the movable abutment holes, that is, the two connecting bolts abut against the adjusting rod 5 in the limiting direction of the adjusting hole 32. The tool assembly 4 is adjusted to deflect to the left or right by adjusting the screwing length of the left and right connecting bolts, and the adjusting rod 5 is connected to the fixed block 3 at the same time.

[0044] The specific method for adjusting the deflection angle of the tool assembly 4 is:

[0045] When the tool assembly 4 needs to work normally, the arc surface of the adjusting rod 5 is set in the limiting direction of the adjusting hole 32. At this time, the adjusting rod 5 cannot move in the limiting direction. The two connecting bolts are screwed into the mounting hole 33 and abut against the positioning abutment hole. The connecting bolts are tightened to connect the adjusting rod 5 to the fixing block 3.

[0046] When the tool assembly needs to be angled left or right, the adjusting rod 5 is rotated so that the arc surface of the adjusting rod 5 is arranged in the moving direction of the adjusting hole 32, and the plane of the adjusting rod 5 is arranged in the limiting direction of the adjusting hole 32. The distance between the two planes of the adjusting rod 5 is smaller than the distance in the limiting direction. Therefore, the adjusting rod 5 can move in the limiting direction. At this time, the two connecting bolts are screwed into the mounting holes 33 and abut against the movable abutment holes. When the tool assembly 4 needs to be angled to the right, the connecting bolt on the left is screwed in for a longer length. When the tool assembly 4 needs to be angled to the left, the connecting bolt on the right is screwed in for a longer length.

[0047] Pneumatic slitting knives are generally fixed on other equipment for use, so a locking through hole 71 is provided on one side of the knife body fixing seat 1, and a locking member is provided in the locking through hole 71. The locking member can move up and down in the locking through hole 71, so that the pneumatic slitting knife is clamped on other equipment. A limiting groove 72 is provided on the side of the locking through hole 71 close to the knife body fixing seat 1, and the limiting groove 72 is connected to the locking through hole 71. The limiting groove 72 is provided with a bottom surface for limiting the movement of the locking member. When the locking member can no longer move downward, it indicates that the movement position of the locking member has reached the limit, thereby preventing excessive clamping of other equipment and preventing the locking member from detaching from the locking through hole 71.

[0048] The locking member includes a locking sleeve 73 and a locking rod 74 inserted in the locking sleeve 73. The locking sleeve 73 is arranged in the locking through hole 71. The lower end of the locking sleeve 73 extends out of the locking through hole 71 for clamping other equipment. The upper end of the locking rod 74 extends out of the locking through hole 71 for easy operation and movement, so that the locking sleeve 73 clamps other equipment. A cover body is provided at the end of the locking rod 74 extending out of the locking through hole 71 for easy grasping by the operator. The connection between the locking rod 74 and the locking sleeve 73 can be pasted, integrally formed or welded, but for the convenience of operation, a limiting groove 741 is provided on the locking rod 74, and a limiting protrusion 732 is provided on the locking sleeve 73, which is an annular groove surrounding the locking rod 74, so that even if the locking rod 74 rotates, the limiting protrusion 732 will not be separated from the limiting groove 741, ensuring the reliable connection between the limiting rod and the limiting sleeve. A limiting block 731 is provided on the locking sleeve 73, and the limiting block 731 is inserted in the limiting groove 72, and the bottom surface of the limiting groove 72 limits the movement of the locking sleeve 73. The position of the limiting block 731 on the locking sleeve 73 needs to ensure that when the limiting block 731 contacts the bottom surface of the limiting groove 72, the locking sleeve 73 will not be separated from the locking through hole 71.

[0049] A knife feed adjustment handle 21 is provided at the end of the main rod 2 close to the knife body fixing seat 1, which can intuitively control the height adjustment of the main rod 2 and further control the cutting depth of the circular knife.

[0050] The utility model mainly designs a pneumatic slitting knife with adjustable deflection angle, and adjusts the angle of the cutter head assembly by setting an adjustment rod 5 and an adjustment hole 32. When the connection between the adjustment rod 5 and the adjustment hole 32 is in a restricted posture, the cutter head assembly is kept in a normal working state by abutting the connection assembly. When the connection between the adjustment rod 5 and the adjustment hole 32 is in an adjusted posture, the cutter head assembly is moved to the left or right by adjusting the position of the connection assembly, so as to achieve the deflection angle of the cutter head assembly and realize cutting of different materials. A locking member and a locking through hole 71 are provided to facilitate connection with other equipment, and the locking member is provided as a locking sleeve 73 and a locking rod 74 for easy operation. The fixing block 3 is provided as a dovetail groove 31, which is clamped with the tool assembly 4, so as to facilitate replacement and maintenance, and easy operation.
