In this way, the clamping assembly 31 is arranged near the new material roll 6, the adsorption structure 313 is firstly utilized to attract the material strip at the outermost layer of the new material roll 6, then the third driving assembly operates to enable the first roller 311 and the second roller 312 to rotate simultaneously, so that the attracted material strip is gradually clamped by the first roller 311 and the second roller 312 under the driving of the second roller 312 in a matched manner, reliable fixing is realized, and meanwhile, the material strip is pulled during the process, so that the material strip is torn along with the material strip, and frequent operation of tearing the material strip by a worker is not needed. Moreover, because the first roller 311 and the second roller 312 are arranged side by side, the material strips are clamped by rotation between the first roller 311 and the second roller 312, no relative displacement is needed, the whole structure of the material clamping assembly 31 is compact and concentrated, the required working space is small, the adaptability is high, the flexible arrangement in the roll changing equipment is convenient, and meanwhile, the layout design of the roll changing equipment where the roll changing assembly is positioned is facilitated. Moreover, since the second roller 312 has the ability to rotate clockwise and counterclockwise, in actual operation, tapes of different rotational directions can be compatible.

In order to ensure more reliable gripping of the head, it is preferable to provide the first roller 311 and the second roller 312 with a length that matches the width of the tape. More specifically, the first roller 311 and the second roller 312 may be disposed side by side in the horizontal direction or may be disposed side by side in the vertical direction, and the arrangement may be specifically selected according to the position of the stub bar of the new roll 6 and the orientation of the nip assembly 31 in the new roll 6. In order to achieve a better effect of pulling the new web, it is preferable to provide the second roller 312 below the first roller 311, and the suction structure 313 is located on the downward facing surface of the second roller 312.

It should be noted that the motor may be replaced with a rotary cylinder.

The first roller 311 and the second roller 312 are driven by one power, the rotation synchronism between the two rollers is strong, and the mode is beneficial to clamping the material belt more tightly due to the rotation along the opposite directions, so that the clamping reliability is high, and the material is not easy to fall off; moreover, the matching mode of the double gears and the power source has low requirement on the assembly space. Of course, the first roller 311 and the second roller 312 can also be configured to rotate in the same direction by using a synchronous wheel structure; alternatively, two motors are provided to drive the first roller 311 and the second roller 312 to rotate, respectively.

In another embodiment, the suction structure 313 includes a suction cup and a negative pressure channel; wherein the suction cups are disposed on the second roller 312; a negative pressure channel is provided in the second roller 312 and communicates with the suction cup to provide negative pressure to the suction cup.

In addition, the clamping component 31 is arranged on the displacement component assembly, and the displacement component assembly can drive the clamping component 31 to move at least along the second direction and the third direction, so that the clamping component 31 is positioned at different positions, wherein the positions comprise a starting station close to the material winding head, and a cutting station for pulling the material winding head to be far away from the material winding to the exposed cutting position of the material belt. The starting mechanism is integrated in a position obliquely above the new roll 6.

So arranged, the clamping assembly 31 clamps the material belt when being positioned at the starting station, and can pull out the material head after moving to the cutting station in a state of clamping the material belt, so that a part of the new material belt is exposed, and the pulled new material belt is cut off in the subsequent belt receiving process; thus, automatic starting is realized, the operation intensity of workers is reduced, and the production efficiency is improved.

In another specific embodiment, the displacement component assembly is provided specifically comprising a fifth drive component 32 and a sixth drive component 33; the clamping assembly 31 is arranged on the sixth driving assembly 33, and the sixth driving assembly 33 can drive the clamping assembly 31 to move and switch between the starting station and the cutting station along the second direction; the sixth driving component 33 is disposed on the fifth driving component 32, and the fifth driving component 32 can drive the sixth driving component 33 to move along the third direction, so that the material clamping component 31 can be moved and switched between the cutting-off station and the standby station; the clamping assembly 31 moves along the second direction and then moves along the third direction, so that the standby station can be moved to the head starting station.

Further, the position where the nip assembly 31 is provided further includes a standby position away from the roll in the axial direction of the roll. Thus, when the new material strip is cut and the strip connection with the old material strip 7 is completed, the clamping assembly 31 leaves along the axial direction of the material roll to avoid interference with the output of the material strip, and the cut waste material is clamped to return to the standby station, and then the waste material is released to wait for the next operation.

In a preferred embodiment, the starting mechanism is provided with a waste collection assembly 34, the waste collection assembly 34 being capable of collecting cut waste released by the clamping assembly 31 at the standby station. Therefore, the cut-off waste is collected in a centralized way, hidden danger that the material belt is disturbed to be output normally due to random discarding is avoided, and workers only need to clean at regular time, so that the manual workload is reduced.

In a specific embodiment, the arrangement of the waste collection assembly 34 includes a collection cassette and a seventh drive assembly that drives the movement of the collection cassette to enable the collection cassette to move below the standby station, in particular the seventh drive assembly may be a pneumatic cylinder, hydraulic cylinder or other linear actuator. Of course, the collecting box may be fixed below the standby position.

The direction layout with respect to the coordinate system formula may be set such that the first direction is a horizontal direction, the second direction is a vertical direction, and the third direction is a horizontal direction perpendicular to the first direction.

In this way, the two groups of driving components enable the clamping component 31 to move in a plane coordinate system, so that the condition of moving and switching among three stations is met, and the electromechanical control is convenient. It should be noted that, the fifth driving assembly 32 and the sixth driving assembly 33 may be configured to drive the screw nut by a motor, or may be a cylinder, a hydraulic cylinder, or other linear actuator.

In a preferred embodiment, the clamping assembly 31 is disposed on a first mount, the fifth drive assembly 32 is disposed on a second mount, the second mount is connected to the frame 5, and the sixth drive assembly 33 is disposed on a third mount; a first guide component extending along a second direction is arranged between the second mounting seat and the third mounting seat; and/or a second guide component extending along a third direction is arranged between the first mounting seat and the second mounting seat.

So set up, the removal of clamp material subassembly 31 is steady smooth and easy, and its position control is more accurate. Specifically, the first guide assembly and the second guide assembly can be both provided as a sliding block and sliding rail type or a linear bearing and a guide rod type.

In another preferred embodiment, the tape splicing device is provided with a pinch roller mechanism provided on the frame 5 for pinching and positioning the used tape 7 in the moving direction of the tape to prevent the used tape 7 from being pulled away by tension. In this way, the old material belt 7 is still output outwards, and the clamping roller mechanism can prevent the old material belt 7 from being drawn away due to poor adsorption capacity of the first positioning structure 11, so that smooth proceeding of the belt receiving process is effectively ensured.

Further, a nip roller mechanism is provided including a passing roller 41 and a pressing roller 42; wherein the passing roller 41 is used for abutting against the material belt; the fourth drive assembly drives the platen roller 42 toward and away from the over roller 41 to pinch and discharge the web. In this way, the old material tape 7 is wound around the passing roller 41 in the output path away from the tape splicing device, and when the tape splicing process is started, the pressing roller 42 operates to press the old material tape 7 against the passing roller 41, and after the tape splicing is completed, the pressing roller 42 is released.

Furthermore, the nip roller mechanism is preferably provided to further include a power source for driving the rotation of the passing roller 41 so that the passing roller 41 can assist the output and the pull-back of the used material web 7.
