The invention relates to a box type film belt cutting and sewing system. For example, the box-type film belt slitting system comprises a working box and a slitting assembly, wherein the working box is provided with two through cutting grooves which are oppositely arranged and used for allowing a film belt to pass through. For example, a containing space is formed in the working box, a through groove is formed in the side wall of the working box, the lancing assembly comprises a driving cylinder and a lancing cutter, and the driving cylinder is mounted on the side wall of the working box. For example, the slitting knife is connected to an output shaft of the driving cylinder, and the slitting knife is slidably inserted into the through groove. For example, the slitting knife is used for reciprocating under the driving of the driving air cylinder so as to cut the film strip in the working box.

Referring to fig. 1 to 5, a box-type film tape slitting system includes a work box 10 and a slitting assembly 20, the work box 10 is provided with two through cutting grooves 11, the two through cutting grooves 11 are oppositely disposed and are used for a film tape to pass through, a slitting area is formed between the two through cutting grooves 11, a receiving space 12 is formed in the work box 10, a through groove is formed in a side wall of the work box 10, the slitting assembly 20 includes a driving cylinder 21 and a slitting knife 22, the driving cylinder 21 is mounted on the side wall of the work box 10, the slitting knife 22 is connected to an output shaft of the driving cylinder 21, the slitting knife 22 is slidably inserted into the through groove, and the slitting knife 22 is used for reciprocating under the driving of the driving cylinder 21 to cut the film tape in the work box 10.

For example, the box-type film tape slitting system is used to pass the film tape through the two through slits 11 and position it. Then, the slit cutter 22 is driven by the driving cylinder 21 to move toward the film tape to cut the film tape inside the work box 10. Because the two opposite sides of the membrane strip can be abutted against the side walls of the two through cutting slots 11 when cutting is stressed, the row opening and the extension of the cutting slots can be reduced, and the length of the cutting slots can be controlled easily.

For example, in order to guide the slitting blade 22 to cut stably, two guide bodies 13 are protruded on the work box 10, and the two guide bodies 13 are respectively located at opposite ends of the through slot. Each of the guiding bodies 13 is provided with a guiding groove, and two opposite sides of the slitting knife 22 are respectively inserted into the guiding grooves of the two guiding bodies 13 in a sliding manner. The passing cutting groove 11 extends in a vertical direction, and the moving direction of the slitting knife 22 is perpendicular to the extending direction of the passing cutting groove 11. The working box 10 is in a rectangular box shape, sliding grooves 14 are further formed in two opposite sides of the working box 10, and the two sliding grooves 14 are arranged oppositely. The sliding groove 14 extends toward the passage incision 11, and the extending direction of the sliding groove 14 is perpendicular to the extending direction of the passage incision 11. The lancing assembly 20 further includes two guide frames 23, and the two guide frames 23 are respectively inserted into the two sliding slots 14. By providing the two guide bodies 13, the opposite sides of the slitting knife 22 can be guided by the guide grooves in the two guide bodies 13, so that the sliding stability of the slitting knife 22 can be improved, and the slitting precision can be improved.

For example, in order to improve the sliding accuracy of the slitting knife 22, the slitting assembly 20 further includes two abutting pieces 24, and the two abutting pieces 24 are respectively protruded on the slitting knife 22 and respectively adjacent to two opposite sides of the slitting knife 22. The supporting member 24 includes an installation block 241 and a supporting strip 242, the installation block 241 is convexly disposed on the slitting knife 22, one end of the supporting strip 242 is fixed on the installation block 241, and the other end slidably supports against the inner side wall of the working box 10. By arranging the two abutting pieces 24, the two abutting pieces 24 can be used for abutting against the inner side of the working box 10 more conveniently, and the sliding smoothness and stability of the slitting knife 22 are further improved.

For example, the present invention provides a slitting process that employs a box film tape slitting system as described above. The slitting method comprises the following steps:

firstly, enabling the membrane strip to pass through the two through slots 11; and

and step two, driving the slitting knife 22 to move towards the film strip by using the driving air cylinder 21 so as to cut the film strip in the working box 10.

For example, it is particularly important that, in order to facilitate the tightening of the membrane strip, the opposite sides of the working chamber 10 are each further provided with a piston chamber 15, wherein the two piston chambers 15 are each adjacent to the two passage slots 11. The piston box 15 is in a rectangular box shape, a rectangular piston 16 is arranged in the piston box 15, the guide frame 23 comprises a penetrating rod and a piston rod 231 which are vertically connected with each other, the penetrating rod is connected to the side edge of the slitting knife 22 and penetrates through the sliding groove 14, one end of the piston rod 231 is vertically connected with the penetrating rod, and the other end of the piston rod is connected with the corresponding rectangular piston 16. A through opening is formed in one end of the piston box 15, which is adjacent to the through slot 11, and a stop frame is arranged at the periphery of the through opening in an inward protruding manner. Each piston box 15 is further provided with a holding box 160 therein, the periphery of one end of the holding box 160 is outwardly protruded with a blocking frame 161, and the blocking frame 161 is used for blocking the blocking frame to prevent the holding box 160 from being separated from the piston box 15. When the slitting knife 22 cuts the film, the two guide frames 23 are used for driving the two rectangular pistons 16 to move so as to push out the two abutting box bodies 160 through air pressure, and the two abutting box bodies 160 are used for flexibly abutting and positioning the two opposite ends of the film strip, so that the slitting knife 22 can cut the film strip. When the slitting knife 22 retreats, the two abutting box bodies 160 can return to the inside of the piston box 15.

For example, after all slitting operations are completed, it is necessary to place a film tape in the work box 10 and close the storage space 12 with the slitting knife 22. The two through slots are movably provided with a trigger frame 115, and the trigger frame 115 is a rectangular frame and protrudes out of the accommodating space 12. A through notch 117 is formed in the middle of the trigger frame 115, and a plurality of slits are formed in the edge of the trigger frame 115 facing the outside of the work box 10. The passing notch 117 is used for passing the slitting knife 22. Each of the trigger frames 115 is provided with two sets of guiding elastic pieces 116, and the two sets of guiding elastic pieces 116 are respectively located at the upper and lower sides of the passing notch 117. Each set of the guiding elastic pieces 116 includes two guiding elastic pieces, and the two guiding elastic pieces 116 are respectively located at two opposite sides of the triggering frame 115. One end of each guiding elastic sheet 116 is connected with the inner side wall of the work box 10, the other end of each guiding elastic sheet is connected with the edge of the trigger frame 115, and the guiding elastic sheets 116 extend obliquely. Two sets of depressions are further formed on the side wall of each through slot 11 corresponding to the two sets of guiding elastic pieces 116. Each set of the recesses includes two recesses on opposite sides of the trigger frame 115. The two recesses correspond to the two guiding elastic pieces 116, respectively. The bottom surface of the slitting knife 22 is also provided with two abutting pieces 24.

After all the lancing operations are completed, the two groups of guiding elastic pieces 116 on each trigger frame 115 are used for guiding the two abutting pieces 24 on one side of the lancing cutter 22 to abut and pass through, the abutting strips 242 of the abutting pieces 24 are moved to the trigger frame 115 along the guiding elastic pieces 116 to force the guiding elastic pieces 116 to enter the recesses, and the trigger frame 115 enters the passing slot 11 and protrudes out of the work box 10. For example, the width of the holding strip 242 is larger than the width of the trigger frame 115, so that the holding piece 24 is not sunk into the trigger frame 115. After the supporting member 24 retreats away from the trigger frame 115, the two sets of guiding elastic pieces 116 guide the trigger frame 115 to reset by using elastic restoring force.

For example, to facilitate closing of the two passage slots 11 of the work box 10 and to maintain a positive pressure inside the work box 10 against the ingress of moisture. An installation groove 1615 corresponding to the through slot 11 is opened on the side wall of each abutting box 160, and the installation groove 1615 is enclosed in the side wall of the piston box 15. An expansion cavity 162 communicated with the piston box 15 is formed in the abutting box body 160, a step groove 163 is concavely formed in the inner side wall of the expansion cavity 162, the bottom surface of the step groove 163 is larger than the area of the mounting groove 1615, and the step groove 163 is communicated with the expansion cavity 162 and the mounting groove 1615. A plurality of communication grooves 164 are formed in a side wall of the mounting groove 1615, one end of each of the communication grooves 164 extends toward the work box 10, and the other end extends toward the step groove 163. The end of the communicating groove 164 is spaced apart from the outer surface of the holding box 160. The movable closing block 17 is installed in the installation groove 1615, the movable closing block 17 includes a closing substrate 171 and a closing body 172 convexly disposed on the closing substrate 171, the closing substrate 171 is clamped into the stepped groove 163, and the closing body 172 is slidably disposed in the installation groove 1615 to close the installation groove 1615, and closes the communication grooves 164 by using a side wall thereof. A compression spring 1625 is arranged in the bulging cavity 162, and the compression spring 1625 abuts against the sealing substrate 171 to enable the movable sealing block 17 to seal the mounting groove 1615.

When the slitting knife 22 performs reciprocating cutting, the abutting box 160 moves back and forth under the action of air pressure to abut and position the film strip or release the film strip. The mounting groove 1615 of the holding box 160 is closed on the side wall of the piston box 15. When the two passing cutting grooves 11 need to be closed after all the cutting operations are completed, the driving cylinder 21 is used for driving the cutting knife 22 to pass through the two trigger frames 115 and abut against the inner side wall of the working box 10 so as to close the accommodating space 12. The abutting piece 24 on the slitting knife 22 is used for abutting against the trigger frame 115 to retract into the through cutting groove 11 and making the trigger frame 115 protrude out of the working box 10, the abutting box body 160 continuously moves forward under the air pressure to make the mounting groove 1615 expose out of the piston box 15 and align with the through cutting groove 11, the trigger frame 115 is clamped into the mounting groove 1615 and pushes the movable closing block 17 to move, the movable closing block 17 moves into the bulging cavity 162 to expose the communication grooves 164, and the pressure gas in the bulging cavity 162 enters into the accommodating space through the stepped groove 163, the communication grooves 164, the cracks on the trigger frame 115 and the through cutting groove 11, so that the accommodating space is kept at a positive pressure to prevent moisture intrusion from the outside. The abutting box 160 and the piston box 15 can ensure the sealing of the receiving space 12. When the lancing operation needs to be performed again, the driving cylinder 21 is used for driving the lancing cutter 22 to retreat so that the abutting piece 24 releases the trigger frame 115, and the trigger frame 115 returns under the action of the guiding elastic sheet 116, in the process, the gas in the accommodating space 12 can enter the piston box 15 to retreat the rectangular piston 16 (even if the return speed of the trigger frame 115 is slow, the return of the abutting box 160 is blocked, because the gas pressure in the piston box 15 is small, the rectangular piston 16 can freely retreat along with the guiding frame 23). Thereafter, the two holding boxes 160 can be pushed into the two piston boxes 15 for the lancing operation to be performed again.

The two piston boxes 15 can improve the moving stability of the cutting knife, position the film belt, and communicate with the accommodating space 12 by the abutting box 160 to keep positive pressure in the accommodating space 12.

After step two, the slitting method further comprises the steps of:

step three: the driving cylinder 21 drives the cutting knife 22 to pass through the two trigger frames 115 and abut against the inner side wall of the working box 10 to close the accommodating space 12, the abutting piece 24 on the cutting knife 22 abuts against the trigger frame 115 to retract into the through cutting slot 11 and causes the trigger frame 115 to protrude out of the working box 10, the abutting box body 160 continuously advances under the air pressure to cause the mounting groove 1615 to expose out of the piston box 15 and align with the through cutting slot 11, the trigger frame 115 is clamped into the mounting groove 1615 and pushes the movable closing block 17 to move, the movable closing block 17 moves into the expansion cavity 162 to expose the communication grooves 164, the pressure gas in the expansion cavity 162 enters into the accommodating space through the step groove 163, the communication grooves 164, the slits on the trigger frame 115 and the through cutting slot 11, so that a positive pressure is maintained in the receiving space to prevent intrusion of external moisture.
