the first roller shaft 91 is rotatably disposed on the machine body 10; each first roller shaft 91 is horizontally arranged, and the first roller shafts 91 are arranged in parallel with each other; the material placing cylinder 92 is arranged on the machine body 10, and the material placing cylinder 92 is positioned below the first roller shaft 91; one end of the swinging rod 93 is connected with the material swinging cylinder 92; the swing central axis of the swing lever 93 is parallel to the axis of the first roller shaft 91; the second roller shaft 94 is rotatably provided on the swing lever 93, and an axial direction of the second roller shaft 94 is parallel to an axial direction of the first roller shaft 91; the first roller shafts 91 are alternately arranged with the second roller shafts 94; the web semifinished product 6 passes through each of the first and second rollers 91, 94 in turn.
In the preferred embodiment, in order to ensure that the coiled material does not deviate, a deviation correction controller 100 can be arranged on the uncoiler 9; the deviation-rectifying controller 100 is located between the discharging speed control device 90 and the material changing area 12 and used for rectifying deviation of the coiled materials.
The working principle of the embodiment is as follows:
the feeding shaft 2 conveys the first coiled material 3 and the second coiled material 4 to a hot pressing device 5, the first coiled material 3 and the second coiled material 4 are pressed into a coiled material semi-finished product 6 through the hot pressing device 5, and then the coiled material semi-finished product is conveyed to a coil separator 9; the feeding device 1 belongs to the prior art, and the specific structure thereof can refer to the prior art, which is not described herein.
A dividing cutter 501 for cutting the coiled material semi-finished product 6 is arranged at the output end position of the hot pressing device 5, the dividing cutter 501 cuts the coiled material semi-finished product 6 into two to three parts, and the dividing cutter 501 can be driven by a motor to cut the coiled material semi-finished product 6, which is not described herein again; at this time, two to three coil separators 9 can be correspondingly arranged at the same time, the cut semi-finished coiled material 6 is guided and conveyed to different coil separators 9 by utilizing the frames 502 of the coil separating guide plates 53, and the direction-changing conveying of the semi-finished coiled material 6 can be realized by arranging guide rollers on the coil separating guide plates 53 in an inclined manner, which is not described herein; the hot pressing device 5 is combined with the structure of a plurality of coil separators 9, so that the coil separating efficiency of the production line can be improved by 2 to 3 times.
The specific working principle of the discharge speed control device 90 is as follows:
and the coiled material semi-finished product 6 is output from the hot-pressing device 5 and sequentially passes through the discharging speed control device 90, the deviation-correcting controller 100, the discharging shaft 72, the material receiving shaft 22 of the material changing area 12 and the material receiving shaft 22 of the material receiving area 13.
The coiled material semi-finished product 6 is output from the hot pressing device 5 to the discharging speed control device 90 and then enters the uncoiler 9, at this time, the rotating speed of the material receiving shaft 22 of the uncoiler 9 may be asynchronous with the feeding speed of the hot pressing device 5, for example, when the turntable 21 drives each material receiving shaft 22 to rotate, the feeding speed of the hot pressing device 5 may be asynchronous with the rotating speed of the material receiving shaft 22, at this time, differential regulation is performed through the discharging speed control device 90, when the material receiving speed of the uncoiler 9 is greater than the feeding speed of the hot pressing device 5, the coiled material on the second roller shaft 94 is strained, so that the oscillating rod 93 swings upwards, and the oscillating cylinder plays a role in stabilizing and damping in the swinging process of the oscillating rod 93; when the material receiving speed of the coil separator 9 is lower than the feeding speed of the hot-pressing device 5, the coil passing through the second roll shaft 94 becomes loose, and the swing rod 93 swings downwards under the action of gravity, so that differential regulation and control of the coil are realized.
The whole working principle of the separator 9 is as follows:
after the semi-finished coiled material 6 passes through the discharging speed control device 90 and the deviation correcting controller 100, the semi-finished coiled material passes through the material swinging shaft 72 and the material receiving shaft 22 of the material changing area 12, and finally the finished coiled material 7 is formed on the material receiving shaft 22 of the material receiving area 13;
after the coiled material of the receiving shaft 22 of the receiving area 13 is coiled to the thickness meeting the specification, the coiled material at the corresponding position is pressed tightly by the tailing press roller 81 and the auxiliary press roller 83, and then the coiled material is cut by the cooperation of the cutting mechanism 30 and the pressing mechanism 70, so that the receiving shaft 22 of the material changing area 12 can be connected with the cut semi-finished coiled material 6, and the winding of a new coiled material is continued; the material receiving shaft 22 of the material receiving area 13 continues to rotate until all the cut tailings are rolled up, and then labeling or sealing is carried out through the labeling mechanism 40, and a labeled coiled material finished product 7 is formed;
after the above actions are completed, the tailing press roller 81 is driven by the tailing pressing cylinder 82 to ascend; at this time, the core feeding mechanism 50 in the core feeding area 11 sleeves the paper core 8 on the material receiving shaft 22 at the position, and then the moving motor 23 drives the turntable 21 to rotate, so that the four material receiving shafts 22 switch positions; the material receiving shaft 22 of the upper core area 11 reaches the material changing area 12 to wait for the next coil material to be cut off and wound with the coil material; the material receiving shaft 22 of the material changing area 12 can drive the coiled material semi-finished product 6 to move to the material receiving area 13 and continue to receive the material, and the material receiving shaft 22 cannot stop running in the whole process, so that the continuous work of the coil separator 9 is realized; the material receiving shaft 22 of the material receiving area 13 carries the labeled finished coiled material 7 to the material discharging area 14, and the finished coiled material 7 is pushed out by the material discharging mechanism 60; the take-up shaft 22 of the discharge area 14 moves to the core loading area 11, and the core 8 is loaded by the core loading mechanism 50.
The specific working principle of the core feeding mechanism 50 is as follows:
the paper core 8 is stored in the paper core 8 storage rack and can fall into the U-shaped clamping groove 521 of the rotating bracket 52 from the opening 511; the rotary driving source 55 drives the rotary bracket 52 to rotate, so that the paper core 8 in the clamping groove 521 falls into the feeding channel 54; by arranging the guide plate 53, the paper core 8 in the clamping groove 521 can not fall off in the rotating process of the rotating bracket 52; after the paper core 8 falls into the feeding channel 54, the paper core can be positioned on the material pushing plate 57, and the material pushing driving source 56 can drive the material pushing plate 57 and the paper core 8 to be sleeved on the material receiving shaft 22 of the upper core area 11; in order to ensure that the paper core 8 is sleeved in the accurate position of the take-up shaft 22, other limiting devices can be further arranged for limiting, and details are not described herein.
The concrete working principle that the coil is cut off by the material cutting mechanism 30 in cooperation with the material pressing mechanism 70 is as follows:
after the coiled material of the material receiving shaft 22 of the material receiving area 13 is rolled to a thickness meeting the specification (how to realize the thickness detection of the coiled material belongs to the prior art, for example, a sensor can be used to detect the thickness of the coiled material in real time, which is not described herein), the tailing pressing roller 81 is driven to press downward by the tailing pressing cylinder 82, and the coiled material at the corresponding position is pressed by the tailing pressing roller 81 and the auxiliary pressing roller 83;
the material pressing driving source 73 drives the material swinging shaft 72 to swing through the pressure swinging disc, so that the material swinging shaft 72 drives the coiled materials on the surface of the material swinging shaft to move until the coiled materials on the surface of the material swinging shaft 72 are contacted with the coiled materials between the material receiving area 13 and the material changing area 12, and at the moment, the coiled materials surround the material receiving shaft 22 of the material changing area 12 in a large range, and the coiled materials are convenient to be subsequently wound on the material receiving shaft 22; meanwhile, the cutting driving source 31 drives the cutting swinging disc 32 to swing, so that the cutting knife 33 is close to the auxiliary cutting knife 34, and the material receiving pressing sheet 71 presses the coiled material to the rotating material receiving shaft 22 of the material changing area 12;
after the coil material is cut off by the material cutting knife 33 and the auxiliary cutting knife 34, the material receiving shaft 22 of the material receiving area 13 continues to rotate until the left coil material tailing after cutting is completely coiled, and then labeling or sealing is carried out through the labeling mechanism 40, and a labeled coil material finished product 7 is formed; the material receiving pressing sheet 71 presses the tail material on the right side to the material receiving shaft 22 of the material changing area 12, so that the material receiving shaft 22 of the material changing area 12 can wind the tail material of the coiled material and wind a new coil of the coiled material; the coiled material on the surface of the material swinging shaft 72 is in contact with the tail material of the coiled material on the right side, and the coiled material on the surface of the material swinging shaft 72 can pull the tail material of the coiled material on the right side to be better wound with the material receiving shaft 22 of the material changing area 12;
finally, the pressing driving source 73 drives the material swinging shaft 72 to swing, so that the material swinging shaft 72 swings and retreats to a position between the material changing area 12 and the hot pressing device 5; meanwhile, the tailing press roller 81 is driven by the tailing press cylinder 82 to ascend; the moving motor 23 drives the turntable 21 to rotate, so that the four material receiving shafts 22 perform position exchange once.
The specific working principle of the discharging mechanism 60 is as follows:
when a new material receiving shaft 22 enters the material discharging area 14 from the material receiving area 13, the material discharging cylinder 61 drives the material discharging pushing member 62 to move, the position of the material discharging pushing member 62 can be in contact with the labeled finished coiled material 7, and the finished coiled material 7 is driven to be separated from the material receiving shaft 22, so that the material discharging action is completed.
Compared with the prior art, the full-automatic continuous production of the packaging roll film is realized by arranging the core feeding area, the material changing area, the material receiving area and the material discharging area on the roll separator and arranging the material receiving shafts at the positions which can be alternately switched in each area; by arranging the material pressing mechanism, the coiled material can be ensured to be tightly attached to the material receiving shaft and finish winding action in the coiled material changing process, and the production line does not need to stop running in the whole production process, so that the production efficiency is greatly improved, and the production cost is saved;
in order to realize continuous work, the production line of the preservative film often causes that the feeding speeds of different roll shafts are inconsistent, and further needs to carry out independent speed regulation and control on each key roll shaft through a plurality of servo motors, and the scheme needs a complex circuit system to monitor and regulate the rotating speeds of different motors, so that the cost of a separator is increased; by arranging the discharging speed control device, the invention can realize the differential adjustment of the feeding speed of the coiled materials on the roller shafts in the hot-pressing device and the coil separator, and solves the problem of inconsistent feeding speed of the coiled materials on the roller shafts

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
