Description

Technical Field

[0001] This application belongs to the field of composite membrane technology, specifically relating to an adjustable composite membrane cutting device. Background Technology

[0002] In the beverage production process, the composite film packaging material used in the filling machine is changed from different rolls of film as production progresses; this is called splicing or film replacement. In existing technology, when replacing the composite film, the new film is cut horizontally. After being heated by a heater, the new film is bonded to the existing film on the machine. This splicing method results in a double-layered overlapping joint, and the new film may have raised edges on the inside of the paper tube. These raised edges become more pronounced after being soaked in hydrogen peroxide during production, potentially causing them to become stuck on the flange of the filling tube. This leads to abnormal equipment shutdown and damages the aseptic filling environment of the filling machine, requiring continuous online cleaning before production can resume.

[0003] In the above process, horizontal plane cutting can cause the joint to warp, which in severe cases can lead to production line shutdown and affect production efficiency. Summary of the Invention

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figures 1 to 7In one specific embodiment of this application, an adjustable composite film cutting device includes: a fixed base 100; and an adjustable support arm assembly 200. The adjustable support arm assembly 200 includes a support arm base 210 and an adjustable support arm 220. Two support arm bases 210 are respectively disposed at both ends of the fixed base 100 along its length and are detachably connected to the fixed base 100. Each support arm base 210 is rotatably equipped with the adjustable support arm 220, and the adjustable support arm 220 is lockable relative to the support arm base 210. The rotation axes of the adjustable support arm 220 are collinear and parallel to the length direction of the fixed base 100; the sliding rail 300 has two ends detachably connected to the ends of the two adjustable support arms 220 away from the fixed base 100; the cutter assembly 400 is slidably disposed on the sliding rail 300 and can slide back and forth along the sliding rail 300, and the cutting plane of the cutter assembly 400 has an angle with the upper surface of the fixed base 100, the angle being adjustable between 1° and 89°.

[0032] In existing technologies, when cutting composite films, the cut surface is typically a plane perpendicular to the surface of the composite film. That is, the cutting plane of the cutter assembly 400 is perpendicular to the upper surface of the fixed base 100. To make the cut surface an oblique plane with a certain angle to the surface of the composite film, the angle between the cutting plane of the cutter assembly 400 and the upper surface of the fixed base 100 should be an acute angle. Depending on the type and thickness of the composite film and the requirements of the production process, this angle should be adjustable between 1° and 89° to adapt to different applications. Further, the angle should be adjustable between 25° and 55°. This angle adjustment is mainly achieved through the adjustable support arm assembly 200. In use, the adjustable support arm 220 can rotate around the support arm base 210 according to actual needs. At this time, the sliding track 300 and the cutter assembly 400 also rotate relative to the fixed base 100 as the adjustable support arm 220 rotates. When the adjustable support arm 220 rotates to the angle between the cutting plane of the cutter assembly 400 and the upper surface of the fixed base 100 (that is, the angle between the adjustable support arm and the upper surface of the fixed base 100) which is the required angle, the adjustable support arm 220 is locked relative to the support arm base 210. The composite film to be cut is placed between the sliding track 300 and the fixed base 100. The cutter assembly 400 is slidable to cut the composite film laterally. At this time, the cut surface is a bevel with a certain angle to the surface of the composite film. This angle is the same as the angle between the cutting plane of the cutter assembly 400 and the upper surface of the fixed base 100, thus realizing the lateral bevel cutting of the composite film. This cut surface significantly improves the adhesion during splicing, reduces the joint thickness, and prevents the inner layer of the joint from warping or bulging. This prevents the warped or bulging parts from getting stuck on the flange of the injection pipe, which could lead to production line shutdowns and reduced efficiency. Furthermore, the angle between the cutting plane of the cutter assembly 400 and the upper surface of the fixed base 100 is adjustable, making it suitable for different types and thicknesses of composite films and various production process requirements, thus adapting to different applications and broadening its scope of use.

[0033] When adjusting the angle between the cutting plane of the cutter assembly 400 and the upper surface of the fixed base 100, the rotational effect resulting from adjusting the connection between the support arm and the support arm base 210 plays a crucial role. Therefore, in a preferred embodiment, the adjustable composite film cutting device further includes a connecting bolt 230. The support arm base 210 is provided with a columnar groove 211, and a connecting portion 212 is provided on one side of the columnar groove 211. One end of the adjustable support arm 220 is provided with a columnar rotating portion 221, which rotatably engages with the columnar groove 211. One end of the connecting bolt 230 passes through the connecting portion 212 and connects to the columnar rotating portion 221. The columnar rotating portion 221 is disposed inside the columnar groove 211, and the connecting bolt 230 passes through the columnar rotating portion 221, allowing the columnar rotating portion 221 to rotate around the connecting bolt 230 within the columnar groove 211. To prevent axial displacement of the cylindrical rotating part 221 within the cylindrical groove 211, a connecting part 212 is provided within the cylindrical rotating part 221. The connecting part 212 is immovable in the axial direction. One end of the connecting bolt 230 passes through the connecting part 212 and connects to the cylindrical rotating part 221. The connecting bolt 230 and the cylindrical rotating part 221 are threaded together. When the connecting bolt 230 is tightened, the cylindrical rotating part 221 is fixed within the cylindrical groove 211, thus preventing axial displacement. Furthermore, the adjustable composite film cutting device also includes a gasket 240. One end of the connecting bolt 230 passes sequentially through the gasket 240 and the connecting part 212 before connecting to the cylindrical rotating part 221. The gasket 240 increases the contact area between the connecting bolt 230 and the connecting part 212, reducing pressure, preventing loosening, and protecting the connecting part 212 and the connecting bolt 230.

[0034] After adjusting the angle between the cutting plane and the upper surface of the fixed base 100 in the previous step, this angle needs to be kept fixed to prevent changes during use. In other words, the adjusting arm and the arm base 210 must be locked together to prevent rotation. Therefore, in a preferred embodiment, the arm base 210 is also provided with a through hole 213, which is perpendicular to the length direction. An arm angle adjusting bolt 250 is provided in the through hole 213 and is threadedly connected to the through hole 213. The columnar rotating part 221 is provided with a friction part 222 in its rotation direction, and one end of the arm angle adjusting bolt 250 extending into the through hole 213 is locked into the friction part 222. When it is necessary to adjust the angle between the adjusting arm and the upper surface of the fixed base 100, that is, when it is necessary to adjust the angle between the cutting plane of the cutter assembly 400 and the upper surface of the fixed base 100, simply loosen the connecting bolt 230 and the arm angle adjusting bolt 250, then rotate the adjusting arm so that the angle between the cutting plane of the cutter assembly 400 and the upper surface of the fixed base 100 reaches the stated angle. Then tighten the connecting bolt 230 and simultaneously tighten the arm angle adjusting bolt 250 so that the end of the arm angle adjusting bolt 250 that extends into the through hole 213 locks (i.e., tightens) with the friction part 222. Due to the combined action of the preload of the adjusting bolt and the friction force of the friction part 222, the columnar rotating part 221 can be prevented from rotating in its rotation direction, thereby keeping the aforementioned angle unchanged during use.

[0035] Furthermore, the friction part 222 is a tooth 223, and the columnar rotating part 221 is arranged with a plurality of teeth 223 in an array in its rotation direction. One end of the support arm angle adjusting bolt 250 that extends into the through hole 213 is provided with a set screw 251. The set screw 251 cooperates with the teeth 223 to lock the adjustable support arm 220 from rotating. As described above, when the angle between the cutting plane of the cutter assembly 400 and the upper surface of the fixed base 100 reaches the required angle, the connecting bolt 230 is tightened, and the support arm angle adjusting bolt 250 is tightened at the same time. At this time, the set screw 251 will extend into the teeth 223 and lock the teeth 223, thereby preventing the columnar rotating part 221 from rotating in its rotation direction, and thus keeping the above-mentioned angle unchanged during use.

[0036] In practical use, due to different production processes, it is necessary to adjust the relative position of the sliding track 300 and the adjustable support arm 220. The adjustable support arm 220 is provided with a number of adjustment holes 225 along its extension direction. The sliding track 300 can be detachably connected to any of the adjustment holes 225, so as to better adapt to different composites and different production lines.

[0037] In another preferred embodiment of this application, the cutter assembly 400 includes a cutter fixing block 410, a cutter 420, and a cutter fixing clamp 430. The cutter fixing block 410 has a sliding through hole 213, and the sliding track 300 is slidably engaged with the sliding through hole 213. The bottom surface of the cutter fixing block 410 is provided with a cutter fixing groove, and the cutter 420 is disposed in the cutter fixing groove. The cutter fixing clamp 430 is detachably connected to the bottom surface of the cutter fixing block 410 and cooperates with the cutter fixing block 410 to clamp the cutter 420. The cutting plane of the cutter 420 has the included angle with the upper surface of the fixing base 100. The cutter 420 slides on the sliding track 300 along with the cutter fixing block 410, enabling lateral cutting of the composite film. The cutter 420 is clamped by the clamping action of the cutter fixing block 410 and the cutter fixing clip 430. The cutter 420 is detachably connected to the cutter fixing block 410 and the cutter fixing clip 430, allowing adjustment of the length of the blade extending beyond the cutter fixing block 410 according to different composite film thicknesses, thus achieving cutting of composite films of varying thicknesses. Furthermore, since the cutter 420 is a consumable part, its blade will dull after prolonged use and require replacement; the aforementioned detachable connection facilitates the replacement of the cutter 420.

[0038] During the transverse cutting of the composite film by the cutter 420, the other end of the blade may be suspended, causing the composite film to be uneven during cutting and resulting in cutting errors. Therefore, the aforementioned adjustable composite film cutting device also includes a cutter plate 500. The cutter plate 500 is disposed on the fixed base 100 and parallel to the sliding track 300. The cutter plate 500 has a cutting groove for cooperating with the cutter 420 for cutting. The cutter plate 500, in cooperation with the cutter, ensures that the cut surface of the composite film remains flat, thereby guaranteeing a stable cut shape.

[0039] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
