DETAILED DESCRIPTION
[0022] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor should belong to the scope of protection of the present application.
[0023] The terms "one embodiment" or "an embodiment" as may be used herein means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the present application. The appearances of the phrase "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily referring to a single, "one embodiment."
[0024] To solve the problems in the prior art, according to an aspect of the present application, a PI film roll forming device is disclosed. Specifically, referring to Figures 1 to 5 As shown in the figure, the device comprises a roll forming rack assembly 1, a feeding assembly 2, and a roll forming assembly 3. The roll forming rack assembly 1 comprises a support frame 11, and the feeding assembly 2 and the roll forming assembly 3 are supported on the support frame 11. The feeding assembly 2 is used to provide PI film 7 for the roll forming assembly 3. The roll forming assembly 3 comprises a plurality of roll jigs and two shaping jigs arranged in sequence and spaced apart in the length direction of the support frame 11 away from the feeding assembly 2. The roll jigs are provided with roll grooves. The circumference of the PI film 7 on the rear roll jigs is based on the circumference of the PI film 7 on the front roll jigs, and the target circumference is achieved by superposition. The rear roll jigs are the roll jigs adjacent to the rear side of the front roll jigs. The two shaping jigs comprise an initial shaping jig 34 and a target shaping jig 35. The initial shaping jig 34 is arranged between the target roll jig 33 and the target shaping jig 35. The target roll jig 33 is the roll jig farthest from the feeding assembly 2 among the plurality of roll jigs. The initial shaping jig 34 performs initial shaping on the target PI roll film obtained by rolling the target roll jig 33 based on the initial shaping groove 341 to obtain an initial shape PI roll film. The target shaping jig 35 performs target shaping on the initial shape PI roll film based on the target shaping groove 351 to obtain a target shape PI roll film.
[0025] Specifically, the number of roll jigs can be specifically set based on the demand for roll circumference.
[0026] In some embodiments, the film shaping assembly 3 may include two film-winding fixtures: an initial film-winding fixture 31 and a target film-winding fixture 33. The initial film-winding fixture 31 has an initial film-winding groove 311, which is configured as a semi-circular structure with a target circumference. The target film-winding fixture 33 has a target film-winding groove 331, which is a spiral structure with a target circumference that is a first target multiple. In this example, the first target multiple can refer to 4 times, that is, the circumference of the target film-winding groove is 4 times the circumference of the initial film-winding groove 311.
[0027] In some other embodiments, the film shaping component 3 may also include an intermediate film rolling fixture 32, which is disposed between the initial film rolling fixture 31 and the target film rolling fixture 33. An intermediate film rolling groove is provided on the intermediate film rolling fixture 32, which is a spiral structure with a second target multiple of the target circumference, the second target multiple being less than the first target multiple.
[0028] It is understandable that the number of intermediate film winding fixtures 32 can be one or more, and the specific number can be set based on the actual film winding requirements. In this example, there are four intermediate film winding fixtures 32. Specifically, as shown... Figure 1 As shown, the film shaping assembly 3 includes an initial film rolling fixture 31, four intermediate film rolling fixtures 32, and a target film rolling fixture 33. The four intermediate film rolling fixtures 32 are disposed between the initial film rolling fixture 31 and the target film rolling fixture 33. The four intermediate film rolling fixtures 32 include a first film rolling fixture 321, a second film rolling fixture 322, a third film rolling fixture 323, and a fourth film rolling fixture 324. The initial film rolling groove 311 of the initial film rolling fixture 31 has a target circumference. The first film rolling groove 3211 opened on the first film rolling fixture 321 is a spiral with a first circumference, the length of which is twice the target circumference of the initial film rolling groove 311 of the initial film rolling fixture 31. The second membrane jig 322 has a second membrane groove 3221, which is a spiral with a second circumference. The length of the second circumference is 2.5 times the target circumference of the initial membrane groove 311. The third membrane jig 323 has a third membrane groove 3231, which is a spiral with a third circumference. The length of the third circumference is 3 times the target circumference of the initial membrane groove 311. The fourth membrane groove 3241 is a spiral with a fourth circumference. The length of the fourth circumference is 3.5 times the target circumference of the initial membrane groove 311. The target circumference of the target membrane groove 331 is 4 times the target circumference.
[0029] It can be understood that, in order to achieve better layering between the PI film roll layers after rolling, the circumference of the rear rolling film slot of the rear rolling film jig can be enlarged by a certain multiple compared to the circumference of the front rolling film slot of the front rolling film jig. The specific enlargement factor can be set based on actual needs, which is not specifically limited here.
[0030] It can be understood that the number of intermediate rolling film jigs 32 can also be other numbers, which are not specifically limited here.
[0031] It can be understood that the technical scheme realizes automatic rolling and shaping of the PI film 7 by setting the rolling film slot and the shaping jig, which is not subject to human subjective influence, improves the rolling efficiency and rolling precision. Moreover, by setting multiple rolling and shaping jigs, the rolling operation of the PI film 7 can be divided into stages, which can be adjusted according to actual needs, adapt to PI films 7 of different specifications and thicknesses, improve the flexibility of production, and the rolling film slot designed on the rolling jig allows the circumference of the film to be adjusted according to different needs, which helps to realize diversified product specifications; further, by setting the initial shaping jig 34 and the target shaping jig 35 to shape the PI film in stages, the stress concentration of the material is reduced, the uniformity of the shaping is improved, and the quality of the target-shaped PI roll film is improved; further, the setting of the intermediate rolling film jig 32, combined with the spiral-shaped slot, can realize gradual rolling, gradually adjusting the shape and size of the film, reducing material stress, and improving the uniformity of the rolling and shaping.
[0032] In some embodiments, the feeding assembly 2 includes a feeding main roller 21, a main roller support 22, a first feeding auxiliary roller 23, a first auxiliary support 24, a second feeding auxiliary roller 25, and a second auxiliary support 26. The feeding main roller 21 is supported above the support frame 11 by the main roller support 22, the first feeding auxiliary roller 23 is supported below the support frame 11 by the first auxiliary support 24, and the second feeding auxiliary roller 25 is supported on the support frame 11 by the second auxiliary support 26. The first feeding auxiliary roller 23 can move up and down relative to the first auxiliary support 24. The PI film is drawn from the feeding main roller 21, passes around the first feeding auxiliary roller 23 and the second feeding auxiliary roller 25, and then reaches the rolling and shaping assembly 3. It can be understood that this scheme can adjust the tension and feeding height of the PI film 7 by adjusting the height of the first feeding auxiliary roller 23, thereby improving the stability of the PI film 7 raw material delivery.
[0033] In some embodiments, the device further comprises a shaping and cutting frame assembly and a shaping and cutting assembly 5, the shaping and cutting frame assembly is arranged on one side of the film shaping frame assembly 1, and the shaping and cutting assembly 5 is arranged above the shaping and cutting frame assembly. The shaping and cutting assembly 5 comprises a butt joint block 51, a cutting shear 52, and a square tube 53 clamp. The butt joint block 51 is arranged close to the target shaping jig 35, and a butt joint groove is formed in the butt joint block 51. The butt joint block 51 slides relative to the target shape PI film, and after sliding, the butt joint block 51 is butt jointed with the square tube 53 clamp to assist the target shape PI film to pass into the square tube 53. The cutting shear 52 is arranged between the butt joint block 51 and the square tube 53, and is used for cutting the target shape PI film. It can be understood that the sliding design between the butt joint block 51 and the target shape PI film ensures that the film material can be accurately butt jointed to the square tube 53 clamp, reduces the error in the butt joint process, and improves the precision of the operation.
[0034] In some embodiments, the device further comprises a conveying assembly 6, which comprises a support column and a conveying auxiliary plate 61. One end of the support column is arranged on the shaping and cutting frame assembly, and the other end of the support column is supported below the conveying auxiliary plate 61. The conveying auxiliary plate 61 is provided with a conveying groove 62, and the target shape PI film is conveyed along the conveying groove 62 to the shaping and cutting assembly 5.
[0035] It can be understood that by conveying the target shape PI film along the conveying groove 62, the groove structure of the conveying groove 62 provides a relatively stable conveying path for the target shape PI film, reduces the displacement or damage of the target shape PI film during the conveying process, improves the safety of the conveying process, and the design of the conveying groove 62 can make the PI film move smoothly along the set trajectory, reduce friction and resistance, and improve the conveying efficiency.
[0036] In some embodiments, the conveying assembly 6 further comprises a pressing plate 63, which is arranged on the conveying auxiliary plate 61 and spans both sides of the conveying groove 62.
[0037] It can be understood that by acting on the conveying auxiliary plate 61 through the pressing plate 63, the target shape PI film can be limited in the conveying groove 62, reducing the accidental falling of the film material during the conveying process, and improving the safety of the operation.
[0038] In some embodiments, the conveying assembly 6 further comprises a front clamping assembly 64 and a rear clamping assembly 65, which are respectively arranged at both ends of the conveying auxiliary plate 61. The target shape PI film passes through the front clamping assembly 64, the conveying groove 62, and the rear clamping assembly 65 in sequence. The front clamping assembly 64 and the rear clamping assembly 65 are out of sync in clamping the target shape PI film.
[0039] In some embodiments, the front clamping assembly 64 includes a front upper clamping plate 641 and a front lower clamping plate 642, and the front upper clamping plate 641 and the front lower clamping plate 642 are closer to or farther from each other to clamp or loosen the target shape PI roll film. The rear clamping assembly 65 includes a rear upper clamping plate 651 and a rear lower clamping plate 652, and the rear upper clamping plate 651 and the rear lower clamping plate 652 are closer to or farther from each other to clamp or loosen the target shape PI roll film. When the target shape PI roll film is clamped by the front clamp, the target shape PI roll film is loosened by the rear clamp. When the target shape PI roll film is loosened by the front clamp, the target shape PI roll film is clamped by the rear clamp. Specifically, in the present example, the rear upper clamping plate 651 and the rear lower clamping plate 652 are closer to each other to clamp the target shape PI roll film, at this time, the front upper clamping plate 641 and the front lower clamping plate 642 are farther from each other, and the front clamping assembly 64 does not act on the target shape PI roll film, so that the target shape PI roll film is moved in the direction of approaching the square tube by the rear clamping assembly 65. After moving in place, the rear upper clamping plate 651 and the rear lower clamping plate 652 are farther from each other, and the rear clamping assembly 65 loosens the target shape PI roll film. At this time, the front upper clamping plate 641 and the front lower clamping plate 642 are controlled to be closer to each other to clamp the target shape PI roll film. The cutting shears 52 are controlled to cut the target shape PI roll film in the clamped state, and further fill the PI film into the next square tube.
[0040] It can be understood that the different step clamping design of the front clamping assembly 64 and the rear clamping assembly 65 can realize flexible control of the target shape PI roll film, avoid material displacement in the clamping and loosening process, and improve the cutting accuracy. The present scheme integrates the roll film, shaping, conveying, clamping and cutting functions, simplifies the operation process, reduces the need for manual intervention, and improves the automation level of roll film shaping.
[0041] The above is only a preferred embodiment of the present application, and is not intended to limit the present application.
