This embodiment includes at least two longitudinal shearing assemblies 110, a switching track 120 and a power assembly 130. The longitudinal shearing assembly 110 is arranged at the working position 140 or the preparation position 150, and the longitudinal shearing assembly 110 is used for longitudinal shearing of the sheet. The switching track 120 connects the working position 140 and the preparation position 150, and the longitudinal shearing assembly 110 moves between the working position and the preparation position along the switching track 120.

The scissor shaft 112 includes an upper scissor shaft 1121 and a lower scissor shaft 1122, the upper scissor shaft 1121 is arranged opposite to the lower scissor shaft 1122, the upper scissor shaft 1121 is located above the lower scissor shaft 1122, the first motor 113 is connected to the upper scissor shaft 1121 through a worm gear 116, and the first motor 113 drives the upper scissor shaft 1121 to approach or move away from the lower scissor shaft 1122. The two ends of the upper scissor shaft 1121 are connected to the fixed bracket 1111 and the movable bracket 1112 on the first frame 111 through the guide rod 117. The first motor 113 is specifically a DC motor. The two ends of the upper scissor shaft 1121 are synchronously moved by the worm gear 116 to ensure that the upper scissor shaft 1121 keeps moving as a whole, thereby achieving stable pressure when the upper scissor shaft 1121 and the lower scissor shaft 1122 are sheared, and a high-precision slitting product is obtained.

[0047] Furthermore, the moving assembly 114 includes a second motor 1141, a transmission chain 1142 and rollers 1143. There are four rollers, and the rollers 1143 are respectively arranged at the four corners of the lower side of the first frame 111. The rollers 1143 roll along the switching track 120. The second motor 1141 is arranged on the first frame 111, and the second motor 1141 is connected to the rollers 1143 through the transmission chain 1142. The second motor 1141 drives the rollers 1143 to rotate through the transmission chain 1142, thereby driving the entire longitudinal shearing assembly 110 to move along the switching track 120. The moving assembly 114 is used to realize the movement of the longitudinal shearing assembly 110 on the switching track 120.

[0048] Specifically, Figure 5 As shown, the scissor shaft 112 includes a shaft body 1123, a sleeve 1124 and an annular blade 1125, and the shaft body 1123 is connected to the clutch assembly 160 through a coupling 115. The annular blade 1125 is sleeved on the shaft body 1123, and the sleeve 1124 is sleeved on the shaft body 1123. The sleeve 1124 and the annular blade 1125 are arranged at intervals.

The annular blades 1125 in the upper scissor shaft 1121 and the annular blades 1125 in the lower scissor shaft 1122 are arranged adjacently and staggered.

[0049] In one embodiment, one end of the scissor shaft 112 is connected to the fixed bracket 1111, and the other end is connected to the mobile bracket 1112. The fixed bracket 1111 and the mobile bracket 1112 are arranged on the first frame 111. The mobile bracket 1112 is slidably connected to the guide rail 1113 provided on the first frame 111. A third motor 1114 is provided below the mobile bracket 1112. The third motor 1114 is connected to the mobile bracket 1112 through a screw rod 1115. The third motor 1114 drives the mobile bracket 1112 to move along the guide rail 1113, approaching or moving away from the fixed bracket 1112. The mobile bracket 1112 moves along the guide rail 1113 to separate from the scissor shaft 112, so as to switch the annular blade 1125 installed on the scissor shaft 112.

[0050] In one embodiment, the power assembly 130 includes a second frame 131, a fourth motor 132, a reduction gear set 133 and a V-type transmission belt 134. The fourth motor 132 and the reduction gear set 133 are arranged on the second frame 131, the fourth motor 132 is transmission-connected to an input gear 1331 of the reduction gear set 133 via the V-type transmission belt 134, and the output gear 1332 of the reduction gear set 133 is transmission-connected to the clutch assembly 160. The fourth motor 132 is specifically a DC motor.

[0051] In one embodiment, the clutch assembly 160 includes a first clutch claw 161, a second clutch claw 162, a clutch claw cylinder 163 and a push rod 164. The first clutch claw 161 is connected to the scissor shaft 112 in the longitudinal shear assembly 110 through a coupling 115. The second clutch claw 162 is transmission-connected to the output gear 1332 of the reduction gear set 133, and the output gear 1332 of the reduction gear set 133 drives the second clutch claw 162 to rotate. The clutch claw cylinder 163 is disposed on the second frame 131, specifically at the top of the second frame 131, and the clutch claw cylinder 163 is connected to the second clutch claw 162 through a push rod 164, and the clutch claw cylinder 163 pushes the second clutch claw 162 to extend and retract to engage or separate with the first clutch claw 161. The first clutch claw 161 and the second clutch claw 162 respectively include a plurality of staggered teeth. The teeth of the first clutch claw 161 and the teeth of the second clutch claw 162 are staggered and engaged with each other to achieve linkage.

[0052] Specifically, the push rod 164 is a U-shaped fork, one end of which is a closed end and the other end is an open end. The second clutch claw 162 is located inside the space clamped by the push rod 164. The middle parts of the push rod arms 1641 on both sides of the push rod 164 are hinged to the two sides of the second clutch claw 162. The head ends of the push rod arms 1641 are connected to form closed ends. An extension section 1642 extends from the closed end of the push rod 164 and is hinged to the telescopic end of the clutch claw cylinder 163. The end of the push rod arm 1641 is hinged to the fixed seat 1643, and the fixed seat 1643 is fixedly connected to the horizontal plane. When the clutch claw cylinder 163 pushes the push rod 164 outward, the push rod 164 drives the second clutch claw 162 to move inward, and the second clutch claw 162 and the first clutch claw 161 are separated. When the clutch claw cylinder 163 pulls the push rod 164 to move inward, the push rod 164 drives the second clutch claw 162 to move outward, and the second clutch claw 162 and the first clutch claw 161 are engaged.

[0053] In one embodiment, the working position 140 is provided with a fixed base 141, the fixed base 141 is provided with a switching track 120, and locking cylinders 142 are provided on both sides of the fixed base 141. The locking cylinders 142 are connected to the locking bevel block 143, and the locking cylinders 142 drive the locking bevel block 143 to move up and down. The first frame 111 in the longitudinal shear assembly 110 is provided with bevel blocks 1116 on both sides, the bevel of the locking bevel block 143 is downward, and the bevel of the bevel block 1116 is upward. The bevel of the bevel block 1116 is opposite to the bevel of the locking bevel block 143, and the size is matched. When the longitudinal shear assembly 110 is located at the working position 140, the locking cylinder 142 pushes the locking bevel block 143 to contact the bevel block 1116, applies pressure to the bevel block 1116, and the longitudinal shear assembly 110 is locked and fixed with the fixed base 141, ensuring that the longitudinal shear assembly 110 remains stable during operation.

[0054] In one embodiment, the preparation position 150 is provided with a mobile base 151, and the mobile base 151 is provided with a plurality of switching tracks, and the plurality of switching tracks 120 are arranged in parallel. The lower side of the mobile base 151 is slidably connected to the mobile guide rail 152, and the setting direction of the mobile guide rail 152 is perpendicular to the setting direction of the switching track 120.

The switching track 120 of the mobile base 151 moves with the mobile base 151 and can be aligned with the switching track 120 of the fixed base 141.

[0055] In this embodiment, the mobile base 151 includes at least two switching rails 120, and the number of longitudinal shearing assemblies 110 is 2. The switching process of the two longitudinal shearing assemblies 110 is as follows: the mobile base 151 moves along the mobile guide rail 152 in the x direction to align the non-loaded switching rail 120 with the switching rail 120 of the fixed base 141. The non-loaded switching rail refers to the switching rail without the longitudinal shearing assembly 110, and the loaded switching rail refers to the switching rail with the longitudinal shearing assembly 110 loaded. The locking bevel 143 of the fixed base 141 releases the longitudinal shearing assembly 110, and the longitudinal shearing assembly 110 moves along the switching rail 120 to the non-loaded switching rail of the mobile base 151. The movable base 151 moves along the movable guide rail 152 in the -x direction, so that the switching track 120 of the longitudinal shearing component 110 to be switched is aligned with the switching track 120 of the fixed base 141, and the longitudinal shearing component 110 to be switched moves along the switching track 120 to the fixed base 141, and the locking bevel block 143 locks the longitudinal shearing component 110, thereby completing the switching.

[0058] The unwinding mechanism 400 is used to load the coiled material, and unwind the coiled material into a sheet and convey it to the flattening mechanism. The first flattening mechanism 200 receives the unwinded sheet and flattens it and conveys it to the first shearing mechanism 300. The shearing mechanism 300 is used to shear the sheet horizontally, and in this embodiment is mainly used to shear the head of the sheet, and the sheet with the sheared head of the sheet is conveyed to the longitudinal shearing mechanism 100. The longitudinal shearing mechanism 100 longitudinally shears the sheet to obtain stripped sheets. The pre-separation mechanism 500 separates the stripped sheets in parallel, and the separated stripped sheets are conveyed to the second flattening mechanism 200 for flattening and the second shearing mechanism 300 for shearing the head of the sheet, and finally conveyed to the winding mechanism 600 for winding to obtain multiple coiled material units. It also includes a film laminating mechanism 700, which is arranged between the flattening mechanism 200 and the shearing mechanism 300, specifically the flattening mechanism 200 and the shearing mechanism 300 between the unwinding mechanism 400 and the longitudinal shearing mechanism 100.

The tension component 520 applies pressure to the strips of the sheet after separation to reduce the lateral displacement of the strips of the sheet to cause overlapping again.

[0061] The tension assembly 520 includes an upper pressing block 521, a lower pressing block 522 and a first oil cylinder 523. The upper pressing block 521, the lower pressing block 522 and the first oil cylinder 523 are arranged on the third frame 510, the upper pressing block 521 is located above the lower pressing block 522, the lower pressing block 522 is fixedly connected to the third frame 510, the upper pressing block 521 and the lower pressing block 522 are arranged opposite to each other, and the space between the upper pressing block 521 and the lower pressing block 522 is used for stripping the sheet. The telescopic end of the first oil cylinder 523 is connected to the upper pressing block 521, and the first oil cylinder 523 drives the upper pressing block 521 to approach or move away from the lower pressing block 522.

[0063] The pressing surface of the upper pressing block 521 and the pressing surface of the lower pressing block 522 are respectively provided with felt 527.

The telescopic assembly 830 is in transmission connection with the coil assembly 840, and the telescopic assembly 830 drives the coil assembly 840 to expand or contract.

Specifically, the supporting surface formed by the support strips 843 is circular, and the cross-sectional size formed by the connecting strips 844 is circular. Because the circular shape of the supporting surface is larger than the cross-sectional size, the size of the supporting surface can match the size of the rotating plate 841.

The outer diameter of the supporting surface surrounded by the supporting bars 843 is larger than the cross-sectional size surrounded by the connecting bars 844. The support bars 843 are used for waste winding in the stretched state.

[0087] When the telescopic assembly 830 drives the rotating shaft 842 to move upward in the axial direction, the support bar 843 shrinks inward, and the lower side of the connecting bar 844 shrinks inward.

The waste strip passes through the guide port 852 and is coiled in the coil assembly 840.

[0091] The lifting cylinder 851 drives the guide opening 852 to move up and down, thereby driving the waste strip passing through the guide opening 852 to move up and down, so as to achieve uniform winding of the waste.

[0092] Furthermore, the guide port 852 includes a support frame 8521 and a plurality of rollers 8522. The support frame 8521 is connected to the telescopic end of the lifting cylinder 851. The rollers 8522 are arranged on the support frame 8521. The plurality of rollers 8522 form a through hole 8523 for the waste strip to pass through. Specifically, the number of rollers 8522 is 4, and the four rollers 8522 form a rectangular through hole 8523.
