The single-channel coiled material conveying mechanism is improved to facilitate the simultaneous conveying of two coiled materials, so that the single-channel coiled material conveying mechanism is high in applicability, can only convey coiled materials of one specification in work, and in real life, the situation that multiple coiled materials of different specifications need to be used often occurs, so that the defects of the single-channel coiled material conveying mechanism are exposed, although processing can be achieved, the continuous replacement of the coiled materials wastes time and labor, meanwhile, because the specifications of the coiled materials are different, the position of the coiled materials needs to be adjusted in the replacement process, and the transmission efficiency of the single-channel coiled material conveying mechanism is low.

Referring to fig. 3-11, to solve the above problems, there is provided a dual path web transfer mechanism including: a feeding assembly 100 comprising two rolls of stored web material, the rolls comprising a first roll 110 and a second roll 120, the first roll 110 and the second roll 120 being arranged one above the other;

a feeding assembly 200, in which a conveying channel for the coiled material on the material roll to pass through is arranged; and

an aftertreatment assembly 300 located at a downstream end of the feed assembly 200;

the feeding assembly 200 comprises a feeding plate 210 and a discharging plate 220, the feeding plate 210 and the discharging plate 220 are sequentially arranged up and down to form a cavity 250 therebetween, and a coiled material is fed from one end close to the feeding assembly 100 to one end close to the post-processing assembly 300 in the cavity 250;

the width of the cavity 250 gradually decreases along the feeding direction until the discharge port downstream of the feeding assembly 200 can receive one roll of the rolls; specifically, referring to fig. 7 to 9, the feeding plate 210 is integrally formed by a first feeding end 213, a first discharging end 212, and a first feeding portion 211 in sequence along the feeding direction, and the feeding plate 210 gradually folds toward the discharging plate 220 along the feeding direction, so that the gap between the feeding plate 210 and the discharging plate 220 is gradually reduced, and finally, the first discharging end 212 and the second discharging end 223 form the discharging port; the feeding plate 210 and the discharging plate 220 form an inverted trapezoid;

the feeding assembly 200 further includes a dividing plate 230 located in the cavity 250, the dividing plate 230 includes a first forming portion 231 and a second forming portion 232, and the feeding plate 210 and the first forming portion 231 are sequentially arranged up and down to form a first dividing channel 251 for conveying one of the coils; meanwhile, the second forming portion 232 and the blanking plate 220 are sequentially arranged up and down to form a second sub-runner 252 for conveying another coiled material; by providing the dividing plate 230 within the cavity 250, the webs from the two rolls are transported in respective flow paths and fed from the same exit port to the aftertreatment assembly 300.

In a preferred embodiment, the dividing plate 230 is in the shape of an elongated plate, and is bent at a position near the middle of the dividing plate 230 along a direction perpendicular to the feeding direction so as to fold the overall shape of the dividing plate 230 into a V shape, the bending position of the dividing plate 230 is a connecting portion 233, and the opening portions of the two ends of the connecting portion are the first forming portion 231 and the second forming portion 232.

The bent shunting plate 230 is convenient to form and high in forming precision, and the bent shunting plate is applied to improvement of a transmission mechanism, is convenient for batch production and saves cost; the addition of the lane plates 230 facilitates the modification of a single-lane web transport mechanism to a dual-lane configuration, meanwhile, the bent shunting plate 230 has high strength, especially at the end of the formed shunting passage, the end position is used as the meeting position of two coiled materials, the connecting part 233 at the end receives the coiled materials in the first shunting passage 251 and is pressed by the coiled materials corresponding to the connecting part, when the coil material in the first shunt passage 251 retracts, the connecting portion 233 acts as a supporting point and receives a larger force, and on the other hand, the coil material in the second shunt passage 252 arches upward to make the connecting portion 233 receive an impact force, the connection part 233 itself is always in a vibration state, and the connection part 233 is laminated by two layers of plates, thereby improving the strength of the end, the strength of the tail end is enough to ensure that the shape of the tail end is in a controllable state in the long-term use process, so that the maintenance cost is reduced.

The first forming portion 231 and the second forming portion 232 are formed by bending the whole block of the channel plate 230, and a common connection manner such as welding is relatively easy to increase the thickness of a connection position if a welding seam exists between the first forming portion 231 and the second forming portion 232 through welding, and the gap between the feeding plate 210 and the discharging plate 220 is not too large, so that the outlet positions of the first branch channel 251 and the second branch channel 252 are reduced to influence discharging, and the connection portion 233 is smaller in thickness through the bending manner, and meanwhile, the strength of the connection portion 233 can be improved through the bending manner; in its bending process, because its radius of bending is little for the whole thickness of connecting portion 233 after the shaping of bending is almost two-layer thick, is favorable to practicing thrift narrow and small passageway internal structure size, and connecting portion 233 improves because of the technology of bending simultaneously, tip intensity, promotes the stability of whole panel structure, and especially when great to panel transverse dimension, the stability of end structure is especially important, avoids the coiled material terminal disturbance that arouses when withdrawing to cause whole panel structure to warp.

Meanwhile, the welding mode is formed by splicing two plates and welding the two plates, the welding technical requirement is higher, the vibration of a channel can be caused due to the fact that coil materials slide in a flow channel and a driver works in the using process, and when the welding line at the tail end of the flow channel is not firmly connected, the coil materials are easy to separate, so that the tail end of the shunt channel deforms and influences use; more importantly, the surface shape of the welding seam is difficult to grasp in the welding process, so that the surface shape of the welding seam is complex, the coiled material is switched, particularly when the coiled material conveyed in the first diversion channel 251 is retracted, the coiled material can be contacted with the welding seam when the coiled material is retracted, and when the coiled material is collided with the welding seam with the complex surface shape, the coiled material is easy to damage by pulling; in the preferred embodiment, the bent connection portions 233 are formed in the bent track plate 230, and the connection portions 233 have smooth transition and high surface quality, so that the coil is not easily damaged when sliding on the connection portions 233.

It should be noted that the technical solution of the shape of the lane plate 230 formed by bending the lane plate 230 is not limited to this, and the lane plate 230 according to the present invention can also be formed by injection molding, such as acrylic plate; however, compared to injection-molded parts, the material of the shunting plate 230 may be selected from: the channeling plate 230 formed by bending common sheet metal such as an aluminum plate, a steel plate, a galvanized plate and the like has moderate surface friction, the coiled material can form proper static electricity when sliding on the channeling plate so as to ensure that the coiled material is attached to the channeling plate, and the surface friction of an injection molding part is too large, so that additional surface treatment is needed, and the manufacturing cost is increased; secondly, the injection molding part is high in hardness but brittle, and for a structure with a large transverse size, the thickness of the injection molding part needs to be increased to ensure the strength of the injection molding part, so that the width of the whole feeding assembly 200 is increased; finally, the injection molding part needs a special mold to be molded, so that the manufacturing cost is increased, and meanwhile, the service life of the injection molding part is low and the wear resistance is poor due to high internal temperature.

Thereby set up lane plate 230 in the appearance chamber 250 and form two subchannel that supply different coiled material to transmit, compare in single channel coiled material transmission mechanism only add lane plate 230, be convenient for change into the binary channels coiled material transmission mechanism of different specification coiled materials with single channel coiled material transmission mechanism, saved manufacturing cost.

As shown in fig. 8, the first forming portion 231 and the second forming portion 232 are inclined with respect to each other, and an included angle α therebetween ranges from 30 ° to 50 °; the shapes of the upper plate 210 and the lower plate 220 correspond to the first forming portion 231 and the second forming portion 232, respectively, and meanwhile, the sizes of gaps at each position in the first sub-runner 251 formed by the upper plate 210 and the first forming portion 231 are the same or approximately the same, and the sizes of gaps at each position in the second sub-runner 252 formed by the lower plate 220 and the second forming portion 232 are the same or approximately the same, so that the widths of the channels in the formed first sub-runner 251 and the second sub-runner 252 are uniform, and the web can be prevented from arching in the runners when passing through the channels.

The preferable range of the gap of the sub-runner is 3.5-8mm, because the coiled material moves in the transmission channel, if the gap is too small, the coiled material is easy to contact with the upper inner wall and the lower inner wall of the transmission channel simultaneously, so that friction is increased, meanwhile, the friction between the coiled material and the inner wall of the transmission channel in the sliding process is easy to generate static electricity, the coiled material bends in the transmission channel, and the coiled material is easy to block in the transmission channel to influence feeding after the gap is too small and the coiled material bends; when the gap is too large, the bending phenomenon is easy to occur due to the fact that the bending amplitude of the coiled material in the transmission channel is increased, so that the coiled material generates creases to influence subsequent use, therefore, after the inventor conducts multiple tests, for example, the paper material in the coiled material adopts the transmission channel with the gap ranging from 3.5 mm to 8mm, and at the moment, the coiled material is smoothly transmitted and is not easy to bend when being fed in the transmission channel; in the above paper materials, such as a0-3 paper or a similar common engineering drawing to a0-3 paper, in practice, a0 and a1 can use the same size of roll, and a2 and A3 use another size of roll, so that although two sizes of rolls are used, four different sizes of drawings can be formed.

Further, the conveying channel includes a feeding end and a discharging end, and the discharging plate 220 includes a second feeding portion 222 and a second feeding end 221, which form the conveying channel with the feeding plate 210, specifically, the second feeding portion 222 is arc-shaped, and the shape of the first feeding portion 211 on the feeding plate 210 corresponds to the second feeding portion 222, so as to form the smooth conveying channel for facilitating the passing of the coiled material; the feeding plate 210 comprises a first feeding portion 211 and a first feeding end 213 respectively corresponding to the second feeding portion 222 and the second feeding end 221; the lower material plate 220 and the upper material plate 210 further include a second discharge end 223 and a first discharge end 212 corresponding to each other, and the second discharge end 223 and the first discharge end 212 form an opening at the discharge end of the transmission channel;

as shown in fig. 11, the ratio of the length (L), the width (D), and the height (H) of the blanking plate 220 is (5-15): (3-5): 1, other plate-shaped structures forming a conveying channel with the blanking plate 220 are correspondingly arranged according to the size of the blanking plate, so that the feeding assembly 200 can convey long coiled materials.

Thereby conveying channel's extension trend is horizontal downwards to the discharge port that is located bottommost position department gradually by the pan feeding port start and is formed the coiled material and get into by pan feeding port department in the conveying channel and receive its self gravity and slide down to discharge port gradually and stretch out in the discharge port, through with conveying channel design is decurrent trend, makes the coiled material be in receive the effect of self gravity simultaneously when conveying channel removes to it is more steady to make the coiled material remove in conveying channel, difficult jam is in conveying channel is interior.

One end of the transmission channel, which is close to the feeding assembly 100, is a feeding end of a coiled material, the feeding assembly 200 further comprises a transmission module 240, and the transmission module 240 is arranged at the feeding end; the transmission module 240 includes two pressing wheels, a common tangent plane 244 is provided between the two pressing wheels, the material roll is disposed below the common tangent plane 244, the pressing wheels include a driving wheel 242 and a roller 243 corresponding to the driving wheel 242, and the transmission module 240 further includes a driving part 241 for driving the driving wheel 242 to rotate; referring to fig. 1 and 2, it is shown that the transmission module 240 is disposed at a central axis of the transmission channel, so that one transmission module 240 can transmit the coiled materials with different specifications, thereby reducing the usage of the transmission module 240, and the feeding plate 210, the discharging plate 220 and the lane dividing plate 230 are provided with a hole for avoiding, so that two transmission modules 240 respectively extend into the first lane dividing channel 251 and the second lane dividing channel 252 to transmit the coiled materials.

In order to correspond to the position of the material roll, the driving wheel 242 is arranged below the tangent plane 244, the roller 243 is arranged above the tangent plane 244, and the material roll and the driving wheel 242 are arranged on the same side of the tangent plane 244, so that the material roll is pressed on the driving wheel 242, the friction force between the material roll and the driving wheel 242 is increased, the driving wheel 242 drives the material roll to move smoothly, and the phenomenon of slipping is avoided; the coil is driven by the driving wheel 242 to move along the feeding direction, so that the coil drives the roller 243 to rotate; the material roll is arranged at a position below the common tangent plane 244 so as to avoid the material roll from contacting the upper material plate 210.

Specifically, the driving wheel 242 is disposed at a connecting position of the second feeding end 221 and the second feeding portion 222, and the roller 243 is disposed at a position corresponding to the feeding plate 210, so that the roller 243 and the driving wheel 242 collide in the conveying channel, the driving wheel 242 drives the coiled material to move, so that the coiled material is driven to rotate, and the coiled material wound thereon is pulled to be continuously fed into the conveying channel; in a preferred embodiment, the web material during the conveying process is tangent to the material roll and the driving wheel 242, and the second feeding end 221 is inclined outwards relative to the common tangent plane 244, so that the second feeding end 221 and the first feeding end 213 of the feeding plate 210 form a feeding opening, the feeding opening is larger than the conveying channel, the design prevents the web material from contacting the second feeding end 221, and the friction is reduced to reduce the moving resistance.

An included angle between the first forming portion 231 and the second forming portion 232 is not too small, and since the transmission module 240 needs to be installed in the first sub-channel 251 and the second sub-channel 252, in order to avoid interference between the two transmission modules 240, the included angle between the first forming portion 231 and the second forming portion 232 is not less than 30 degrees; simultaneously, first shaping portion 231 with contained angle between second shaping portion 232 should not be too big, when the contained angle is too big, makes the interval increase of two material rolls, thereby has increased the ascending height of whole equipment vertical direction, and more seriously, along with the interval increase of two material rolls, the height that is located the material of top is too high, will increase the degree of difficulty of material loading, because the material that will use up is rolled up and is changed, and the material of full volume is rolled up weight great, because material is rolled up and is changed the position and rised, the degree of difficulty that leads to changing improves greatly, wastes time and energy.
