Description

Technical Field

[0001] The utility model relates to the technical field of slitting knives, in particular to a slitting mechanism in which the falling knife and the air pressure of the knife do not interfere with each other. Background Art

[0002] Before the pneumatic slitting knife works, it is necessary to perform the knife lowering (slitting knife moves downward) and knife leaning (slitting knife moves left and right) actions to align the knife. The size of the knife leaning force is an important factor affecting the slitting quality. If the size of the knife leaning force needs to be adjusted, it is usually achieved by ventilating the inside through the knife leaning air hole of the knife head seat through a separate external air source to push the knife head shaft to move left and right, so as to drive the blade on the knife head shaft to move closer to the lower knife.

[0003] In the prior art, the above-mentioned knife-leaning and knife-lowering actions are provided with gas through one air source, that is, one air source supplies air to the knife-lowering module and the knife-leaning module at the same time, resulting in the air pressure values of the two actions of knife-leaning and knife-lowering being basically the same. However, in actual use, the air pressure value required for the knife-leaning action is usually not greater than the air pressure value of the knife-lowering action, resulting in poor flexibility of the prior art. Summary of the Invention

DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0019] like Figures 1 to 4 As shown, the utility model provides a cutting mechanism in which the air pressure of the falling knife and the leaning knife do not interfere with each other, comprising a machine body 1, an air supply module 2 and a cutting knife module 3 both arranged on the machine body 1, the air supply module 2 being used to drive the cutting knife module 3 to drop the knife and lean the knife, the machine body 1 is also provided with a pressure regulating module 4, the air supply module 2 having a falling knife air duct 21 and a leaning knife air duct 22, and the pressure regulating module 4 being used to adjust the air pressure value of the leaning knife air duct 22.

[0020] In actual use, the cutting knife module 3 has a corresponding falling knife structure 31 and a leaning knife structure 32. These two structures are conventional structures in the pneumatic cutting knife and will not be described here; and the air supply module 2 is provided with an air pipe 29 for connecting to the external air source 5.

[0021] Specifically, the air supply module 2 of the present invention is supplied with air by an external air source 5, and the gas is transmitted to the falling knife air duct 21 after passing through the air supply module 2. Subsequently, the air supply module 2 switches its state, so that the air pressure value of the falling knife air duct 21 remains unchanged while being connected to the blade-supporting air duct 22. The air pressure value of the blade-supporting air duct 22 can be adjusted according to actual needs through the pressure regulating module 4. Since the falling knife air duct 21 is equivalent to being blocked after switching the state, adjusting the air pressure value of the blade-supporting air duct 22 will not affect the air pressure value of the falling knife air duct 21, achieving the effect of preventing the falling knife air duct 21 and the blade-supporting air duct 22 from interfering with each other, thereby improving the flexibility of the present invention.

[0022] In this embodiment, the pressure regulating module 4 includes a pressure regulating valve 41 movably disposed on the body 1 . The pressure regulating valve 41 is connected to the knife-edge air passage 22 . The pressure regulating valve 41 is used to adjust the air pressure value in the knife-edge air passage 22 .

[0023] In actual use, the pressure regulating valve 41 can be set between the external gas source 5 and the knife-supporting air duct 22, that is, the gas enters the knife-supporting air duct 22 after passing through the pressure regulating valve 41, and the staff can adjust the air pressure value of the knife-supporting air duct 22 according to the pressure regulating valve 41.

[0024] Specifically, the pressure regulating module 4 further includes a pressure gauge 42 disposed on the machine body 1 , and the pressure gauge 42 is used to indicate the air pressure value of the knife-side air channel 22 .

[0025] As an embodiment, the pressure gauge 42 has two ends, which are respectively connected to the pressure regulating valve 41 and the knife-supporting air duct 22, so that the gas needs to pass through the pressure regulating valve 41 before it can be transmitted to the knife-supporting air duct 22, so that the pressure gauge 42 can accurately sense the air pressure value and display it, which is convenient for the staff to control the pressure regulating valve 41.

[0026] Specifically, the air supply module 2 also includes a knob 23 rotatably arranged on the body 1, and the rotating shaft 24 of the knob 23 has an air inlet end 25, and the air inlet end 25 is used to connect to the external air source 5. The knob 23 has at least one air outlet end 26, and the air inlet end 25 is connected to the two air outlet ends 26 through the knob 23. The knob 23 rotates relative to the body 1 to adjust the connection status of the two air outlet ends 26 with the falling knife air duct 21 and the knife-supporting air duct 22 respectively.

[0027] That is, the interior of the knob 23 is a hollow structure, and only one air outlet end 26 may be provided, or if there are multiple air outlet ends 26 , the other air outlet ends 26 may be blocked by a sealing member 28 to prevent air leakage. The rotating shaft 24 of the knob 23 is always connected to the external air source 5 to ensure that the rotation of the knob 23 will not affect the introduction of gas; and the rotation of the knob 23 is used to realize the switching of the air outlet end 26 between the connection with the falling knife air duct 21 and the connection with the knife-supporting air duct 22, that is, when the air outlet end 26 is connected with the falling knife air duct 21, the gas enters the falling knife air duct 21 and makes the falling knife air duct 21 and the falling knife structure reach the required air pressure value; then the knob 23 is rotated to make the air outlet end 26 connected with the knife-supporting air duct 22, so that the external air source 5 can supply air to the knife-supporting air duct 22. At this time, the knob 23 or the seal 28 of the knob 23 will block the knife-supporting air duct 21 to avoid air leakage in the knife-supporting air duct 21, so as to achieve the effect that the knife-supporting and knife-supporting air pressures do not interfere with each other.

[0028] In this embodiment, the knob 23 is provided with a shift block 27, which is used to feedback the current position state of the knob 23, so that the staff can intuitively know the working state to which the knob 23 is currently switched, which is convenient for control.

[0029] In this embodiment, the body 1 is provided with a control groove 11, and the knob 23 is installed in the control groove 11. The control groove 11 is provided with an axial hole 12 for accommodating the rotating shaft 24 of the knob 23. The control groove 11 is connected to the falling knife air channel 21 and the supporting knife air channel 22. That is, the knob 23 is assembled with the rotating shaft 24 through the axial hole 12, and the relevant air channels are formed in the body 1 instead of providing an air pipe to communicate with the rotating shaft 24, so as to avoid air leakage when the knob 23 is rotated. In addition, the supporting knife air channel 22 and the falling knife air channel 21 are also formed in the body 1 through conventional processes such as stamping, die-casting or drilling. Therefore, they are directly connected to the control groove 11, so that after the knob 23 is rotated, the sealing member 28 at the corresponding position can reliably seal the air channel that is not connected to the external air source 5, thereby ensuring the sealing effect of the present invention.

[0030] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention, which do not depart from the content of the technical solution of the present invention, are within the scope of the technical solution of the present invention.
