In this embodiment, the wrapping mode and the wire breaking mode of the packaging film are both the prior art, and the utility model is designed deeply based on the prior art, aiming at the problem of edge twisting and folding during the paying-off of the packaging film, while the wrapping mode and the wire breaking mode in the prior art can refer to the structure shown in fig. 1, and include a rotating roller group 1a (rotatable, which facilitates the object to adjust the wrapping position of the wrapping mode), a pushing frame 1b disposed at the bottom of the rotating roller group and rotationally connected with the fixing frame 1, and a pushing rod 1c rotationally connected with the pushing frame 1b and the fixing frame 1, wherein the side wall of the rotating roller group 1a is provided with a plurality of limiting clamp shafts for clamping the converged packaging film.
After the wrapping action of changing the position is continuously performed, after the wrapping action is completed, the push rod 1c can push the pushing frame 1b to deflect around the rotating point rotationally connected with the fixing frame 1, so that the rotating roller group 1a is inclined, then the inclined rotating roller group 1a can push the object to gradually slide out, meanwhile, the packaging film can be converged towards the limiting clamping shaft area and clamped into the limiting clamping shaft area, and once the object is separated from the rotating roller group 1a, the packaging film is torn off, that is, the limiting clamping shaft area can clamp the end of the torn packaging film.
In order to prevent the pull-back member 5 from occurring in the case of the overall deviation of the wide packaging film, it is preferable that the rotating lever assembly 2 includes a pair of rotating levers 21 rotatably connected to the film roll frame 3, and both ends of each rotating lever 21 are sleeved with the pull-back member 5.
The clamping cylinder group 4 comprises two clinging cylinders 41, the two clinging cylinders 41 are respectively sleeved at the same ends of the two rotating rods 21 in a one-to-one correspondence manner, the end parts of the clinging cylinders 41 are provided with mounting grooves 42, and the inner walls of the mounting grooves 42 are fixedly connected with the end faces of the pull-back pieces 5.
The packaging film is limited by the two rotating rods 21, so that the packaging film can only move between the two rotating rods 21, the two ends of each rotating rod 21 are provided with the clinging cylinder 41, so that both sides of the packaging film can be limited, and when the packaging film is clinged by the clinging cylinder 41, the packaging film cannot contact the pull-back piece 5 (preferably a spring) because the pull-back piece 5 is positioned in the mounting groove 42, and the situation that the packaging film is damaged can be avoided.
Although the two close-fitting cylinders 41 can clamp one side of the packaging film, once, it is preferable that a plunger ring 43 is provided on the side wall of one of the close-fitting cylinders 41, and a plurality of locking tooth blocks 45 are provided on the side wall of the plunger ring 43; a pressing groove 44 is formed in the other side wall of the close-fitting cylinder 41 and corresponds to the pressing ring 43; the tucker ring 43 can push the edge of the packaging film into the tucker groove 44.
For ease of viewing and understanding, the left side is denoted d and the right side is denoted e as shown in fig. 3.
In this embodiment, the positioning tooth block 45 has two embodiments, when the packaging film is thinner, the positioning tooth block 45 selects softer foam cotton or sponge material, which plays a role in increasing friction force with the packaging film; embodiment two: when the packaging film is thicker, and when the flexibility is stronger, the metal material can be selected to screens tooth piece 45 this moment, set up in the tamponade groove 44 of e side simultaneously with screens tooth piece 45 complex punching groove (not shown in fig. 3), realize carrying out the effect that the edge punched a hole was fixed a position after the packaging film passed through, and this embodiment can cooperate the structure in fig. 6 to operate, when the packaging film punched a hole and fixed a position the back, when the roller bearing in fig. 6 of rethread, the roller bearing in this fig. 6 can set up and collude the post for collude in the post can imbeds the hole that the packaging film was punched out, prevent the packaging film rocking.
When the packaging film is introduced between d and e, the edge of the packaging film is pushed by the plunger ring 43 to enter the plunger groove 44, that is, part of the edge area of the packaging film is pushed into the plunger groove 44 by the plunger ring 43, so that the edge of the packaging film cannot easily slide along the cling cylinder 41 when being subjected to larger oblique pulling force, and after the edge of the packaging film is pushed into the plunger groove 44, the friction force of the packaging film can be increased by the arrangement of the plurality of clamping tooth blocks 45, so that the anti-skid performance of the packaging film is higher.
If the central area of the packaging film is not pressed, the packaging film can shake up and down between the two rotating rods 21, so that the edge of the packaging film in the pressing groove 44 slides, therefore, preferably, the central area of each pair of rotating rods 21 is fixedly sleeved with a pressing cylinder 22, and both ends of the pressing cylinder 22 are respectively provided with a pushing piece 23 which is sleeved on the side wall of the rotating rod 21 and is fixedly connected with the corresponding close-fitting cylinder 41 at the end part of the pressing cylinder 22.
The outside of each pushing piece 23 is sleeved with a defending ring group 24 with the end part fixedly connected with the end part of the middle pressing cylinder 22 corresponding to the pushing piece 23, a sliding groove 25 is formed in the position, corresponding to the defending ring group 24, of the side wall of each clinging cylinder 41, and one end, far away from the middle pressing cylinder 22, of the defending ring group 24 extends into the sliding groove 25.
The packaging film passing between d and e is pressed by the middle pressing cylinder 22 on the two rotating rods 21 at the same time, and then the central area of the packaging film is limited, that is, the packaging film is simultaneously pressed by the middle pressing cylinder 22 and the two pressing cylinders 44, so that the positions of the packaging film can be limited by forces in three directions, and the problem of deviation of the packaging film can be greatly prevented.
When the packaging film is tilted, the abutting cylinder 41 moves toward the side of the centering cylinder 22, and guides the pushing member 23 and the pulling-back member 5 to elastically deform.
However, when the gap between the press cylinder 22 and the close cylinder 41 is large, the sliding close cylinder 41 is easily scratched and the pushing member 23 is easily hooked, so that when the close cylinder 41 moves toward the press cylinder 22, the guard ring set 24 slides along the sliding groove 25 to separate the packaging film from the gap between the press cylinder 22 and the close cylinder 41.
Because the tight-fitting cylinder 41 is sleeved on the rotating rod 21, when the tight-fitting cylinder 41 is driven to move by the packaging film, once the tight-fitting cylinder 41 and the middle-pressing cylinder 22 are subjected to speed difference, namely relative movement, the phenomenon that the packaging film is torn easily occurs, so that preferably, the outer side wall of the defending ring set 24 is flush with the outer side wall of the middle-pressing cylinder 22, and the defending ring sets 24 at the same end of each pair of middle-pressing cylinders 22 can be respectively pressed on the surfaces of two sides of the packaging film.
By the arrangement, the packaging film is fully prevented from being pressed by the pressing middle cylinder 22, so that the distortion phenomenon is avoided, and the distortion part is prevented from being broken due to the inclination of the packaging film.
Traction grooves 26 are formed in the surfaces of the guard ring groups 24 located on two sides of the packaging film, driving strips 27 are arranged in the traction grooves 26 in the surfaces of one guard ring group 24, one ends of the driving strips 27 extend into sliding grooves 25 corresponding to the guard ring group 24 along the surfaces of the guard ring group 24, and inserting blocks 28 are arranged at the other ends of the driving strips 27.
When the close-fitting cylinder 41 moves toward the middle pressing cylinder 22, the guard ring set 24 slides along the sliding groove 25, and the driving bar 27 drives the insert block 28 to slide along the traction groove 26, so that the sliding insert block 28 cannot shake easily, that is, cannot generate relative movement.
Since the packaging film is subjected to forces from three directions simultaneously, the pulling-out phenomenon is liable to occur once it is too tight, it is preferable that the surface of the insert block 28 is provided with a push-out bump 29.
A push block 210 is arranged in the traction groove 26 on the surface of the other defending ring set 24; when each pair of rotating rods 21 rotates simultaneously, the traction groove 26 on one guard ring set 24 is opposite to the traction groove 26 on the other guard ring set 24 and causes the ejector block 210 to push the insertion block 28 toward the side of the centering cylinder 22.
When the d-side guard ring set 24 rotates simultaneously with the e-side guard ring set 24, once the traction groove 26 on the d-side guard ring set 24 rotates opposite to the traction groove 26 on the e-side guard ring set 24, the d-side insert block 28 will be inserted into the traction groove 26 on the e-side guard ring set 24 with the push bump 29, and during this process, the push block 210 in the e-side traction groove 26 pushes the insert block 28 towards the side of the press cylinder 22, so that the close cylinder 41 will move towards the side of the press cylinder 22 (that is, no external force is applied any more, for example, the packaging film is not inclined at this time), and then, the two sides of the packaging film will move towards the central area, thereby reducing the pressure of the packaging film.
After the packaging film is broken again, the packaging film is in a tight state, at the moment, the packaging film is larger in force from the direction of the close-fitting cylinder 41, and the phenomenon that the broken end of the packaging film is separated from the limiting clamping shaft easily occurs, so that preferably, one side of the middle pressing cylinder 22, which is close to the fixing frame 1, is provided with a fixing column 211 connected with the film roll frame 3, the side wall of the fixing column 211 is provided with an expansion cylinder 212 with adjustable size, the side wall of the expansion cylinder 212 is provided with a limiting ring groove 213, and the limiting ring groove 213 can limit the packaging film.
When the packaging film is torn, the volume of the expansion cylinder 212 is reduced immediately (the volume control mode of the expansion cylinder 212 can be composed of an air pump and an electromagnetic valve opening, when the expansion cylinder is inflated, the air pump is opened, the electromagnetic valve is closed, and when the expansion cylinder is contracted, the air pump is closed, the electromagnetic valve is opened), that is, the tightening force between the clamping shaft and the clinging cylinder 41 is reduced.
The side wall of the expansion cylinder 212 is provided with a bulge area 214, the bulge area 214 can bulge against the central area of the packaging film, and a driving roller 215 is arranged in the bulge area 214.
Once the expansion cylinder 212 is required to be inflated (that is, the packaging film is pulled out and wound on the side wall of the object at this time), the bulge area 214 can push the central area of the packaging film to bulge, and the roller 215 is driven to guide the movement of the packaging film, so that the packaging film cannot slide and rub with the bulge area 214 all the time, and the packaging film is scratched.
The driven roller 215 includes a raised section 2151 and a sloped section 2152 disposed within the raised region 214 and connected in sequence, the sloped section 2152 having a length greater than the length of the raised section 2151.
When the packaging film is lifted by the lifting area 214, the contact area between the lifting section 2151 and the inclined section 2152 pushes the packaging film to lift a point (the point represents an area of the packaging film to be unfolded first) so as to guide the edge of the packaging film to be unfolded towards two sides, and the inclined section 2152 has a longer length so that the contact with the packaging film is larger and the phenomenon that the edge of the packaging film shakes due to too fast rotation can not occur.
In this embodiment, the second embodiment of the driving roller 215 is as shown in fig. 6, and the second embodiment of the re-matching of the positioning tooth block 45 is thus provided.
The working principle of the utility model is as follows: in the whole winding work, the rotating roller group is driven to rotate through the rotating shaft arranged on the fixing frame 1, at the moment, the object can rotate (the packaging film is clamped by the limiting clamping shaft) to pull the packaging film to be wound on the side wall of the object, at the moment, the object can be driven by the rotating roller group 1a to rotate to change the winding position, and when the subsequent packaging film contacts the packaging film clamped by the limiting clamping shaft, the packaging film can push the end part of the packaging film clamped by the limiting clamping shaft to be separated from the limiting clamping shaft.
After the wrapping action of changing the position is continuously performed, after the wrapping action is completed, the push rod 1c can push the pushing frame 1b to deflect around the rotating point rotationally connected with the fixing frame 1, so that the rotating roller group 1a is inclined, then the inclined rotating roller group 1a can push the object to gradually slide out, meanwhile, the packaging film can be converged towards the limiting clamping shaft area and clamped into the limiting clamping shaft area, and once the object is separated from the rotating roller group 1a, the packaging film is torn off, that is, the limiting clamping shaft area can clamp the end of the torn packaging film.
When the packaging film is released:
the position of packaging film can be restricted through two dwang 21 for packaging film can only move between two dwang 21, and the both ends of every dwang 21 all are provided with and hug closely section of thick bamboo 41, make the both sides of packaging film can both be restricted, and when the packaging film was hugged closely by hugging closely section of thick bamboo 41 centre gripping, because the pull back piece 5 is in mounting groove 42, the packaging film can not contact pull back piece 5 (preferably spring) because of pull back piece 5, can avoid the condition emergence that the packaging film was damaged.
For ease of viewing and understanding, the left side is denoted d and the right side is denoted e as shown in fig. 3.
When the packaging film is introduced between d and e, the packing film edge is pushed by the packing ring 43 to enter the packing groove 44, that is, part of the packing film edge area is pressed into the packing groove 44 by the packing ring 43, so that the phenomenon that the packing film edge slides along the cling cylinder 41 easily when being subjected to larger oblique pulling force can not occur, and after the packing film edge is pressed into the packing groove 44, the friction force of the packing film can be increased by the arrangement of the plurality of clamping tooth blocks 45, so that the anti-skid performance of the packing film is higher.
The packaging film passing through the gap between d and e is also pressed by the middle pressing cylinder 22 on the two rotating rods 21, and then the central area of the packaging film is limited, that is, the packaging film is simultaneously subjected to the pressure from the middle pressing cylinder 22 and the two pressures pressed into the plug pressing grooves 44, so that the positions of the packaging film can be limited by the forces in three directions, and the problem of deviation of the packaging film can be greatly prevented.
When the packaging film tilts (for example, when the packaging film is clamped by the limiting clamp shaft, the packaging film tilts and converges a little), the cling cylinder 41 moves towards the side of the centering cylinder 22, and the pushing member 23 and the pull-back member 5 are guided to elastically deform.
However, when the gap between the press cylinder 22 and the close cylinder 41 is large, the sliding close cylinder 41 is easily scratched and the pushing member 23 is easily hooked, so that when the close cylinder 41 moves toward the press cylinder 22, the guard ring set 24 slides along the sliding groove 25 to separate the packaging film from the gap between the press cylinder 22 and the close cylinder 41.
When the close-fitting cylinder 41 moves towards the middle pressing cylinder 22, the guard ring set 24 slides along the sliding groove 25, and the driving bar 27 drives the insertion block 28 to slide along the traction groove 26, so that the sliding insertion block 28 cannot shake easily, that is, cannot generate relative movement.
When the d-side guard ring set 24 rotates simultaneously with the e-side guard ring set 24, once the traction groove 26 on the d-side guard ring set 24 rotates opposite to the traction groove 26 on the e-side guard ring set 24, the d-side insert block 28 will be inserted into the traction groove 26 on the e-side guard ring set 24 with the push bump 29, and during this process, the push block 210 in the e-side traction groove 26 pushes the insert block 28 towards the side of the press cylinder 22, so that the close cylinder 41 will move towards the side of the press cylinder 22 (that is, no external force is applied any more, for example, the packaging film is not inclined at this time), and then, the two sides of the packaging film will move towards the central area, thereby reducing the pressure of the packaging film.
When the packaging film is torn off:
the expansion cylinder 212 can be reduced in volume immediately, i.e. the tightening force between the wrapping film re-restraining clamp shaft and the abutment cylinder 41 is reduced.
Once the inflation barrel 212 is required to be inflated (i.e., the package film is pulled out and wrapped around the side wall of the object), the inflation area 214 is able to push the central region of the package film to bulge, so that the package film is provided with a buffer section when cut later, and the package bag will not be pulled off by the broken end.
When the packaging film is lifted by the lifting area 214, the contact area between the lifting section 2151 and the inclined section 2152 pushes the packaging film to lift a point (the point represents an area of the packaging film to be unfolded first) so as to guide the edge of the packaging film to be unfolded towards two sides, and the inclined section 2152 has a longer length so that the contact with the packaging film is larger and the phenomenon that the edge of the packaging film shakes due to too fast rotation can not occur.
Compared with the prior art, the utility model can realize the aims of preventing the edges of the packaging film from twisting and preventing the whole deviation in the winding process by the clamping cylinder groups 4 and the pull-back pieces 5, and in the specific implementation, the edges of the packaging film can be directly clamped by the clamping cylinder groups 4, so that the edges of the packaging film can not twist easily in the releasing process, and once the packaging film is wholly deviated and the clamping cylinder groups 4 are driven to slide, each pull-back piece 5 can apply traction force to the corresponding clamping cylinder groups 4 to reset the clamping cylinder groups 4 sliding along the rotating rod groups 2, thereby enabling the packaging film to wholly and rapidly reset and preventing the phenomenon that the inclined packaging film is twisted and folded at the edges of objects in the subsequent winding process.
The utility model also provides a film releasing method of the horizontal packaging film winding device, which comprises the following steps:
s100, dragging the packaging film to sequentially pass through the rotating rod and the expanded expansion cylinder so that two sides of the edge of the packaging film are tightly clamped by the cylinder;
s200, pulling out the packaging film by rotating the object for a set time, winding the packaging film on the side wall of the object, and pushing the object to rotate in the rotating process so as to change the winding position of the packaging film;
s300, pressing the central area of the surface of the pulled packaging film through the guard ring groups on two sides of the packaging film to limit the whole deviation of the packaging film, and enabling the pushing block to push the insertion block to move towards one side of the middle pressing cylinder in the process of the traction groove of the side wall of the guard ring group on two sides of the packaging film so as to traction and clamp the edge of the packaging film to move towards one side of the middle pressing cylinder;
s400, pushing the object to incline after the rotation is completed for a set time, and guiding the packaging film on the side wall of the expansion cylinder to converge to a point so as to break the packaging film by the object sliding out of the fixing frame;
s500, reducing the diameter of the expansion cylinder to reduce the pulling force of the cling cylinder and the defending ring group on the packaging film;
s600, rotating the object for a set time again to pull out the packaging film and wind the packaging film on the side wall of the object, and guiding the end part of the packaging film converged to a point to be separated from the convergence point when changing the winding position of the packaging film, and gradually expanding the expansion cylinder until the expansion cylinder cannot expand;
when the expansion cylinder is gradually expanded, the contact area of the tilting section and the inclined section pushes a little of the packaging film to bulge so as to guide the edge of the packaging film to expand towards two sides (namely, push the middle first, namely, apply force to the middle first, thereby avoiding that the packaging film cannot be quickly expanded due to the integral application of force to the packaging film, and only the folded area needs to be pulled out first and then can be expanded).
The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements may be made to the present application by those skilled in the art, which modifications and equivalents are also considered to be within the scope of the present application.
