In addition, the functional mechanisms are respectively installed on the machine base 60.

With continuing reference to fig. 1, 3 and 4, in some embodiments, the reel-up mechanism 20 includes a mounting frame 21, a first driving member, a first transmission member, a material shaft 22 and a roller-passing member 23, the first driving member and the material shaft 22 are disposed on the mounting frame 21 and are mutually and drivingly connected through the first transmission member, and the roller-passing member 23 is disposed at one side of the material shaft 22 in a side-by-side spaced manner. In this embodiment, the first driving member is a motor, the first driving component is a pulley set, and the material shaft 22 is an expansion shaft. The outer part of the material shaft 22 is tightly fixed with a wide roll of material, which can be aluminum foil or other metal materials, mobile phone films, etc. In the present embodiment, aluminum foil is preferable. During operation, the first driving part drives the first transmission assembly to rotate, and the first transmission assembly synchronously drives the material shaft 22 to rotate, so that the wide roll raw material can be rotationally conveyed out to enter a subsequent processing station.

With continued reference to fig. 3 and 4, in some embodiments, the dedusting mechanism 30 is disposed in the path of travel after the wide roll of stock material is fed out. The dust removing mechanism 30 includes a mounting seat, a fixing shaft and a brush 31, the fixing shaft is disposed on the mounting seat and is located below the wide roll material sent out by the material shaft 22, and the brush 31 is disposed on the fixing shaft and is in contact with the surface of the wide roll material. The brush 31 can be fixed on the mounting seat through a fixed shaft, the wide roll of raw material sent out at the moment can be contacted with the brush 31 and slide with each other when moving through the dust removal mechanism 30, and the brush 31 can clean up the impurities such as dust, flock and the like which are contaminated by the wide roll of raw material, thereby being beneficial to improving the product quality.

Further, the brush 31 is arranged on the entire outer peripheral wall of the fixed shaft. The fixed shaft can be round, square and the like. The brush 31 is fully distributed on the peripheral surface of the fixed shaft, so that the brush 31 can continuously clean the continuously moving wide roll of raw material in the rotating process of the fixed shaft, and the cleaning dead angle on the wide roll of raw material is avoided.

Alternatively to the above embodiment, the brush 31 has a spiral structure and is disposed on the outer circumferential wall of the fixed shaft to extend in the axial direction of the fixed shaft. The difference from the above embodiment is that the brush 31 has a spiral structure, which not only has the function of continuously cleaning the wide roll of raw material, but also significantly reduces the material consumption of the brush 31 itself, which is beneficial to reducing the manufacturing and using costs.

Of course, in other embodiments, other modifications of the structure, installation manner, etc. of the brush 31 may be adopted, and are also within the protection scope of the present application.

In addition, in order to further enhance the dust removing capability of the brush 31, in addition to the above embodiment, the dust removing mechanism 30 further includes a second driving member for outputting a rotational power, the second driving member is disposed on the mounting seat and connected to the fixed shaft, and the rotation direction of the brush 31 is opposite to the moving direction of the wide roll material. In this embodiment, the second driving member is a motor, and the motor drives the fixed shaft to rotate, so that the brush 31 can rotate in a direction opposite to the moving direction of the wide roll of raw material, and at this time, the brush 31 can enhance the scraping capability of the impurities on the surface of the wide roll of raw material under the relative motion relationship.

Or, in still other embodiments, the fixed shaft, the brushes 31 and the second driving member are at least two and three of them are assembled and connected in a one-to-one correspondence manner, and at least two brushes 31 are arranged side by side and are all in contact with the surface of the wide roll of raw material. Thus, the plurality of brushes 31 are arranged side by side and are in contact with the wide roll of raw material, so that the cleaning area in unit time can be increased, and the dust removal efficiency is improved.

Further, the dust removing mechanism 30 further comprises an air source, an air pipe and an air nozzle, wherein the air nozzle is connected with the air source through the air pipe, and the air nozzle is arranged on the mounting seat and used for spraying air flow to the surface of the wide roll raw material. So, the air supply passes through the trachea and carries high-pressure gas to the jet head, and the jet head sprays high-pressure draught to the wide raw materials surface of rolling up afterwards, can blow off impurity. And the air flow cleaning way cooperates with the brush 31 to further improve the cleaning capability of the dust removing mechanism 30.

In still other embodiments, the dust removing mechanism 30 further comprises a vibrator disposed on the fixed shaft to generate high-frequency micro-amplitude vibration of the brush 31. Because the brush 31 can generate high-frequency micro-amplitude vibration under the drive of the vibrator, the brush 31 forms impact force on the impurities stained on the surface of the wide roll raw material, and the brush 31 has a scraping effect on the impurities and can quickly and effectively remove the impurities. Alternatively, the vibrator may be, but is not limited to, a vibration motor.

With continuing reference to fig. 4, in still other embodiments, the dust removing mechanism 30 further includes a negative pressure generator, a negative pressure pipeline, and a negative pressure suction nozzle 32, the negative pressure suction nozzle 32 is connected to the negative pressure generator through the negative pressure pipeline, and the negative pressure suction nozzle 32 is disposed at one side of the brush 31 and near the wide roll of raw material. Therefore, the negative pressure suction nozzle 32 can generate suction force to suck and recycle the parts such as the brush 31 and the like to remove the impurities such as the falling dust and the like from the wide roll raw material, and the pollution to the machine and the environment caused by the falling impurities scattered around is avoided.

Preferably, the negative pressure suction nozzle 32 is a wide flat structure or a cylindrical structure, and the length of the negative pressure suction nozzle 32 is not less than half of the width of the wide roll of raw material; or, there are at least two negative pressure suction nozzles 32, and at least two negative pressure suction nozzles 32 are arranged at intervals. Through adopting above-mentioned two kinds of embodiments, can promote suction efficiency and the effect to the impurity that drops, realize impurity and thoroughly clear away.

The dust removing mechanism 30 further includes a dust collecting box connected to the negative pressure generator. The impurities such as dust sucked by the negative pressure suction nozzle 32 can be collected and recovered into the dust collection box, so that the dust collection box is convenient to be regularly and intensively treated.

With reference to fig. 4, in view of the problem that the brush 31 generates a reaction force on the wide roll of raw material when rotating in a reverse direction relative to the wide roll of raw material, so that the wide roll of raw material is deflected and folded, thereby affecting the conveying reliability, the dust removing mechanism 30 further includes a pressing rod 33 and a flexible strip 34, the pressing rod 33 is disposed above the mounting seat at an interval, and the flexible strip 34 is disposed on the bottom surface of the pressing rod 33 and is opposite to the mounting seat at an interval. The wide roll of raw material slides over the upper surface of the mounting seat, and the mounting seat supports and lifts the wide roll of raw material; meanwhile, the pressing rod 33 above the mounting seat can generate proper pre-pressing force on the wide roll of raw materials, so that the harmful influence of the resistance of the brush 31 on the wide roll of raw materials can be effectively eliminated, and the wide roll of raw materials can be prevented from sliding and wrinkling. And because the flexible strip 34 is additionally arranged on the pressure lever 33, the flexible strip 34 is directly contacted with the wide roll of raw material, and the product quality is not influenced by scratching.

Alternatively, the flexible strip 34 is made of rubber, foam, or the like.

With reference to fig. 5 and fig. 6, on the basis of any of the above embodiments, the material cutting wiping mechanism 40 includes a fixed seat, an active cutter 41, a passive cutter 42, a third driving member 43 and a shifting assembly 44, the third driving member 43 is disposed on the fixed seat and is in rotational driving connection with the active cutter 41, the passive cutter 42 is rotatably disposed on the fixed seat and is spaced from and opposite to the active cutter 41, and the shifting assembly 44 is disposed on the fixed seat and can drive the active cutter 41 to approach or depart from the passive cutter 42.

In this embodiment, the third driving member 43 is a motor. In the initial state, the displacement assembly 44 is reset and the active cutter 41 is moved away from the passive cutter 42 to form a through passage through which the incoming wide roll of stock material can pass. During machining, the motor drives the driving cutter 41 to rotate at a high speed, and at the same time, the shifting assembly 44 drives the driving cutter 41 to approach the driven cutter 42 continuously. At a certain moment, when the driving cutter 41 is close to the driven cutter 42 and the driving cutter 41 and the driven cutter are simultaneously contacted with the front surface and the back surface of the wide roll of raw material, the driven cutter 42 supports and positions the wide roll of raw material, and the driving cutter 41 can cut the wide roll of raw material into at least two paths of narrow rolls of raw material (raw material with small width).

With reference to fig. 5, further, the driving cutter 41 includes a main cutter shaft 411 and at least two blades 412 axially spaced apart from each other on the outer circumferential wall of the main cutter shaft 411, the driven cutter 42 includes an auxiliary cutter shaft 421 and a cutter sleeve 422 sleeved outside the auxiliary cutter shaft 421, the cutter sleeve 422 is provided with at least two cutter grooves 423 circumferentially extending and axially spaced apart from each other along the auxiliary cutter shaft 421, and the blades 412 can be inserted into the cutter grooves 423 in a one-to-one correspondence manner. The blade 412 extends into the knife groove 423, so that the blade 412 can generate enough pressure on the wide roll of raw material, and the blade 412 penetrates through the thickness direction of the wide roll of raw material, so that complete cutting can be ensured, and the phenomenon that the product quality is influenced due to pulling caused by incomplete cutting and incomplete adhesion during subsequent shunt movement can be prevented.

In this embodiment, the blades 412 are in an annular cutter head structure, fixed on the main cutter shaft 411 through fasteners, and arranged perpendicular to the axial direction of the main cutter shaft 411. The width of the sipe 423 is slightly larger than the thickness of the blade 412 to ensure that the blade 412 is more easily inserted into the sipe 423, reducing the probability of collision interference.

Further, at least one side of the groove wall of the cutter groove 423 is provided with a cutter grinding body. Thus, when the blade 412 is inserted into the knife groove 423 to cut the wide roll of raw material, the blade 412 is in rotational contact with the knife sharpener, which grinds the edge of the blade 412 and strengthens the cutting ability of the blade 412, so that the blade 412 is renewed over time.

Further, the rotation directions of the driving cutter shaft and the driven cutter shaft are opposite, so that the blades 412 and the cutter grooves 423 are rotatably staggered. Due to the fact that the rotation directions are opposite (namely that one of the driving cutter shaft and the driven cutter shaft rotates clockwise and the other one rotates anticlockwise), a certain shearing effect can be formed, and the wide roll raw material can be cut off completely.

With continued reference to fig. 1 and 6, in addition to any of the above embodiments, the cut material wiping mechanism 40 further includes a blade cleaning assembly 45, the blade cleaning assembly 45 includes a fixing block 451, a pressing plate 452, and a wiping member 453, the pressing plate 452 is connected to the fixing block 451 and mounts and fixes the wiping member 453 on the fixing block 451, and the wiping member 453 can wipe off impurities on the blade 412. The wiping member 453 is firmly installed by pressing the pressing plate 452 and the fixing block 451, and when the blade 412 rotates to cut the wide roll of raw material, the blade 412 contacts with the wiping member 453, so that the wiping member 453 can clean impurities such as dust stained on the blade 412 after cutting the wide roll of raw material, and the quality of the narrow roll of raw material is guaranteed.

Preferably, on the basis of the above embodiment, the wiping member 453 is a wiping sponge, and the wiping sponge is soaked with alcohol. The wiping sponge soaked with alcohol has stronger impurity removal capability and has a cleaning effect on narrow rolls of raw materials.

With reference to fig. 7 and fig. 8, in addition to any of the above embodiments, the displacement assembly 44 includes a first driving wheel 441, a second driving wheel 442, a third driving wheel 443, a fourth driving wheel 444, a sliding rail module 445 and a driving rod 446, the first driving wheel 441 is in driving connection with the third driving member 43, the second driving wheel 442 is in driving fit with the first driving wheel 441, the third driving wheel 443 is coaxially connected with the second driving wheel 442, the fourth driving wheel 444 is in driving fit with the third driving wheel 443, the fourth driving wheel 444 is in threaded driving fit with the driving rod 446, the driving rod 446 is connected with the fixing seat, and the fixing seat is disposed on the sliding rail module 445.

In this embodiment, the third driving member 43 is a motor, and a power shaft of the motor is arranged downward. The first driving wheel 441 and the second driving wheel 442 are rubber wheels and are arranged with vertical axes, so that when the motor drives the first driving wheel 441 to rotate, the second driving wheel 442 can be synchronously driven to rotate, and the second driving wheel 442 can further drive the main knife shaft 411 to rotate together, so that the blade 412 can cut wide rolls of raw materials. Meanwhile, the third driving wheel 443 is coaxially connected to the second driving wheel 442, the third driving wheel 443 can synchronously drive the fourth driving wheel 444 to rotate, and since the fourth driving wheel 444 is connected to the driving rod 446 by a screw pair, the driving rod 446 can drive the fixed seat to slide on the sliding rail module 445, and the driving cutter 41 immediately moves close to the driven cutter 42, so that the blade 412 and the knife groove 423 cooperate to complete the slitting operation of the wide roll of raw material. The shifting assembly 44 has the advantages of compact structure, strong cooperation of all stations, high response speed and capability of improving the efficiency of material slitting operation.

With reference to fig. 6, the cut material wiping mechanism 40 further includes a dust collector, a dust collecting pipe and a dust collecting plate 46, two ends of the dust collecting pipe are respectively connected to the dust collector and the dust collecting plate 46, the dust collecting plate 46 is provided with a plurality of dust collecting holes, the dust collecting holes are communicated with the dust collecting pipe, and the dust collecting plate 46 is located below the driving cutter 41 and the driven cutter 42. Therefore, the scraps and dust generated in the process of cutting the wide roll raw material can be sucked into the dust collector through the dust suction pipe through the dust suction hole, so that the scraps and the dust are prevented from flying around to cause environmental pollution and harm the health of workers.

Further, the cut material wiping mechanism 40 further includes a lifting module, and the lifting module is connected to the dust suction plate 46 so that the dust suction plate 46 can be close to or far from the active cutter 41 and the passive cutter 42. During operation, the lifting module lifts the dust suction plate 46 to rise to be close to the driving cutter 41 and the driven cutter 42, and the suction capacity is enhanced by reducing the distance, so that the fragments and dust generated by cutting can be completely absorbed. When the lifting module and the dust suction plate 46 are in the non-working state, the lifting module and the dust suction plate are retracted to be in the low position, so that interference on movement of other parts can be avoided.

Alternatively, the lifting module may be, but is not limited to, a telescoping rod mechanism, a lead screw slider mechanism, a scissor fork mechanism, and the like.
