[0028] like Figures 1 to 4 As shown, the embodiment of the present invention provides a film rolling device for packaging film production, which includes a frame 10, a feed roller 20 and a film rolling assembly 40. The feed roller 20 is arranged on one side of the top of the frame 10 and is connected to the frame 10. The feed roller 20 is adjustably arranged on two limit plates 30. When the packaging film roll 80 is installed on the feed roller 20, the two limit plates 30 respectively abut against the two ends of the packaging film roll 80; the film rolling assembly 40 includes a power part 41, a winding roller 42, a first film splicing roller 43 and a second film splicing roller 44. The first film splicing roller 43 and the second film splicing roller 44 are connected to the frame 10 and form a staggered distribution. The first film splicing roller 43 is located between the second film splicing roller 44 and the unloading roller 20, and the second film splicing roller 44 is located below the first film splicing roller 43. The winding roller 42 is located between the first film splicing roller 43 and the second film splicing roller 44. The power member 41 is located on the outside of the frame 10, and the output end of the power member 41 passes through the frame 10 and is connected to one end of the winding roller 42, which is used to drive the winding roller 42 to rotate to realize the winding of the packaging film.
[0029] The film rolling equipment for packaging film production based on the above technical features loads the packaging film roll 80 into the unloading roller 20. At this time, the two limit plates 30 are located on both sides of the packaging film roll 80. Then, the positions of the two limit plates 30 on the unloading roller 20 are adjusted so that the two limit plates 30 respectively abut against the two ends of the packaging film to complete the assembly of the packaging film roll 80. The structure is simple and the assembly is convenient. The relative positions of the two limit plates 30 can be adjusted according to needs. It is suitable for rolling packaging films with different inner diameters, which is beneficial to reducing costs. After the packaging film roll 80 is assembled, one end of the packaging film is passed through the first film splicing roller 43 and the second film splicing roller 44 in turn, and is wound onto the winding roller 42. Then, the power part 41 is used to drive the winding roller 42 to rotate so that the packaging film is wound onto the winding roller 42, thereby realizing automatic film rolling of the packaging film. The structure is simple and the operation is convenient.
[0030] In one possible embodiment, a locking member 90 is further included. A connecting portion extends outward from the outer surface of the limiting disk 30. The connecting portion has an axial hole formed therein along its axial direction. The limiting disk 30 has a through hole connected to the axial hole. The locking member 90 is provided at the connecting portion, and one end of the locking member 90 is used to abut against the discharge roller 20 to lock the limiting disk 30 on the discharge roller 20. In this way, when winding packaging film rolls 80 with different inner diameters, it is necessary to adjust the position of the limiting disk 30 on the discharge roller 20 until the limiting disk 30 is adjusted to abut against the end surface of the packaging film roll 80. By tightening the locking member 90 so that one end of the locking member 90 continuously approaches the discharge roller 20 until the locking member 90 abuts against the surface of the discharge roller 20, the limiting disk 30 is locked, which can effectively prevent deviation during the film winding process, thereby resulting in poor film quality.
[0031] In one possible embodiment, connecting plates 60 extend outward from the two outer side walls of the top of the frame 10. A mounting groove 60a is defined at one end of the connecting plate 60 away from the frame 10. The end of the discharge roller 20 is fixed in the mounting groove 60a to achieve connection between the discharge roller 20 and the frame 10. In other words, when the packaging film roll 80 is inserted into the discharge roller 20 and then mounted on the frame 10, the end of one end of the discharge roller 20 is first inserted into the mounting groove 60a of one connecting plate 60, and then the other end of the discharge roller 20 is inserted into the mounting groove 60a of the other connecting plate 60, thereby assembling the packaging film roll 80 to be wound. This has a simple structure and is easy to assemble.
[0032] In one possible embodiment, a clamping block 70 is further included. The clamping block 70 is used to secure the end of the discharge roller 20 inserted into the mounting groove 60a. The clamping block 70 is detachably connected to the connecting plate 60. In this way, after the end of the discharge roller 20 is inserted into the mounting groove 60a, the clamping member is used to clamp the end of the discharge roller 20 in the mounting groove 60a to prevent the discharge roller 20 from jumping out of the mounting groove 60a during the film rolling process, thereby preventing the packaging film roll 80 from being properly unwound and affecting the film rolling efficiency.
[0033] In one possible embodiment, a first fixing hole is formed on the connecting plate 60, and a second fixing hole is formed on the top of the frame 10 to match the first fixing hole. Thus, by placing the end of the connecting plate 60 with the fixing hole in contact with the connecting plate 60, the first fixing hole and the second fixing hole are aligned. Fasteners are then passed through the first and second fixing holes, respectively, to securely connect the connecting plate 60 to the frame 10. This provides a simple structure and easy assembly and disassembly.
[0034] In one possible embodiment, a tension roller 45 is further included. The tension roller 45 is located below the winding roller 42 and can be moved vertically toward or away from the winding roller 42 to adjust the tension of the packaging film. Thus, the tension roller 45 can be used to adjust the tension of the packaging film to ensure that the packaging film is always in a certain tension state, preventing wrinkles in the packaging film during the winding process, which could affect the quality of the rolled film.
[0035] In one embodiment, the frame 10 has two symmetrical extension bars 50 extending downward in the vertical direction. Each extension bar 50 defines a first adjustment hole 50a. The ends of the tension roller 45 extend into the first adjustment holes 50a and connect to the extension bars 50. In other words, because the ends of the tension roller 45 extend into the first adjustment holes 50a and connect to the extension bars 50, the tension roller 45 can be adjusted within the first adjustment holes 50a, thereby enabling adjustment of the tension roller to meet the different tensioning requirements of different packaging films.
[0036] In one possible embodiment, two axisymmetric connecting plates 60 are further included. The two connecting plates 60 are respectively provided on the inner side surface of the frame 10, and the two ends of the first receiving roller are respectively connected to the top ends of the two connecting plates 60, so that the first receiving roller spans the inside of the frame 10. In this way, by providing two connecting plates 60 on the inner side surface of the frame 10 and then connecting the two ends of the first receiving roller to the top ends of the two connecting plates 60, the first receiving roller is connected to the frame 10, which has a simple structure and convenient connection.
[0037] In one possible embodiment, the connecting plate 60 has a second adjustment hole along its length, and the inner side of the frame 10 has a mounting hole that matches the second adjustment hole, so that the height of the first receiving roller can be adjusted. In other words, when the height of the first receiving roller needs to be adjusted, the fasteners extending into the mounting hole and the second adjustment hole are loosened, and the connecting plate 60 is then adjusted vertically to drive the first receiving roller to adjust. After the first receiving roller is adjusted to the desired height, the fasteners are then re-entered through the mounting hole and the second adjustment hole and tightened. This allows the first receiving roller to be adjusted to meet different receiving requirements.
[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
