Technical Field
[0001] This application relates to the technical field of thin film production, and in particular to a thin film roll splitting device. Background Technology
[0002] Film rolls are a general term in the packaging industry for packaging films supplied in rolls. A film roll is a roll formed by winding continuous film material onto a mandrel. It mainly consists of a film and a mandrel. The film is the main part of the film roll and is made of various polymer materials, such as polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), and polyester (PET). Different materials have different performance characteristics. The mandrel is usually made of paper or plastic and is used to support the film roll, keeping it in a wound state for easy transportation, storage, and use.
[0003] Common film roll slitting equipment mainly consists of a cutting element and a support roller. When cutting the film roll, it is placed directly on the support roller for cutting. Relying solely on the support roller for support and fixation results in poor stability during cutting, inconvenient adjustment of the cutting length, low overall cutting efficiency, and inconsistent cutting quality. Summary of the Invention
[0004] To improve stability, efficiency, and quality during cutting, this application provides a film roll splitting device.
[0005] The film roll splitting device provided in this application adopts the following technical solution:
[0006] A film roll slitting device includes a worktable with a drive screw threaded through one side. A mounting frame is fixedly installed at the top of the worktable, and a cutting assembly is fixedly installed at the top of the mounting frame. Two second fixed vertical plates are symmetrically fixedly installed in the middle of the worktable. A second support rod is fixedly connected to one side of each of the two second fixed vertical plates. A sliding block is slidably connected to the middle of each second support rod, and a lifting assembly is fixedly connected to the top of each sliding block. An internal support assembly is driven and installed on one side of the lifting assembly. A support assembly is symmetrically fixedly connected between the two second support rods. A manual drive assembly is driven and connected inside the mounting frame. Support legs are fixedly connected to the four corners of the bottom of the worktable. During use, this device can support and internally fix the film roll, ensuring stable fixing of the film roll and guaranteeing cutting stability and quality. Simultaneously, the film roll can move on the support rollers, making it convenient to adjust the cutting length and improving cutting efficiency.
[0007] Preferably, the cutting assembly includes a telescopic cylinder, with a telescopic cylinder embedded in the middle of the top of the telescopic cylinder, a lifting frame fixedly connected to the bottom of the telescopic cylinder, a cutting machine body fixedly installed on one side of the lifting frame, and guide rods symmetrically fixedly installed on the top wall of the telescopic cylinder. The guide rods facilitate more stable movement of the lifting frame.
[0008] Preferably, the lifting assembly includes four plug-in columns, which are respectively fixedly connected to the four corners of the top of the sliding block. A movable frame is slidably connected to the top of the four plug-in columns. An adjusting screw is rotatably connected to the middle of the top of the sliding block. The adjusting screw and the movable frame are threadedly connected. The sliding block is penetrated by a driving screw and the two are threadedly connected. The rotation of the driving screw allows the sliding block to slide.
[0009] Preferably, the inner support assembly includes a drive motor, which is fixedly installed on the side of the movable frame away from the mounting frame. A drive shaft is rotatably connected to the side of the movable frame near the mounting frame. The drive shaft and the output shaft of the drive motor are connected in a transmission connection. Two fixed ring seats are fixedly connected to one end of the drive shaft, and a sliding ring seat is threaded to the other end of the drive shaft. Limit grooves are symmetrically opened on the outer side of the drive shaft. A positioning nut is threaded to the side of the mounting frame near the movable frame. Support arms are rotatably connected to the outer sides of the two fixed ring seats and one sliding ring seat. An inner support block is rotatably connected to the top of each support arm. The fixed ring seats cooperate with the sliding ring seats, support arms, and inner support blocks to make the distance between the inner support blocks adjustable, which is convenient for supporting different film roll cores.
[0010] Preferably, the support assembly includes two first fixed vertical plates, which are symmetrically and movably connected inside the mounting frame. Each of the two first fixed vertical plates is rotatably connected to a support roller, and the outside of the support roller is rotatably connected to several universal ball bearings, so that the film roll can rotate and move on the support roller, making it convenient to adjust the position of the film roll.
[0011] Preferably, the drive assembly includes a bidirectional lead screw, which passes through one side of the mounting frame. First support rods are symmetrically mounted inside the mounting frame. The bidirectional lead screw is threadedly connected to two first fixed vertical plates. The first support rods pass through the two first fixed vertical plates. Adjusting wheels are fixedly connected to the ends of both the bidirectional lead screw and the drive lead screw, providing a point of leverage for the operator to rotate the bidirectional lead screw and the drive lead screw, facilitating easy and labor-saving adjustment.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The design incorporates a first fixed vertical plate, a support roller, universal ball bearings, a first support rod, and a bidirectional screw. By rotating the bidirectional screw and screwing the two first vertical plates together, the two first fixed vertical plates can move closer to or further away from each other, which facilitates the support of film rolls of different diameters. At the same time, the film rolls can move along the axis of the support roller on the support roller using the universal ball bearings, which facilitates the cutting of film rolls of different lengths.
[0014] The device incorporates a drive shaft, plug-in column, adjusting screw, sliding block, adjusting wheel, fixed ring seat, sliding ring seat, limiting groove, positioning nut, support arm, and inner support block. By rotating the positioning nut, the sliding ring seat is positioned, allowing the inner support block to provide support from inside the film roll core shaft, thus improving the stability of the film roll placement.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0021] This application discloses a film roll splitting device.
[0022] See Figures 1-4The film roll cutting equipment includes a worktable 1, a drive screw 15 passing through one side of the worktable 1, an installation frame 2 fixedly installed at the top of the worktable 1, a cutting component fixedly installed at the top of the installation frame 2, two second fixed vertical plates 13 symmetrically fixedly installed in the middle of the worktable 1, a second support rod 14 fixedly connected to one side of each of the two second fixed vertical plates 13, a sliding block 21 slidably connected to the middle of the second support rod 14, a lifting component fixedly connected to the top of the sliding block 21, an internal support component installed on one side of the lifting component, a support component symmetrically fixedly connected between the two second support rods 14, a manual drive component connected internally to the installation frame 2, and support legs 3 fixedly connected to the four corners of the bottom of the worktable 1.
[0023] Furthermore, the cutting assembly includes a telescopic cylinder 4, which is embedded in the middle of its top. A lifting frame 5 is fixedly connected to the bottom of the telescopic cylinder 4. A cutting machine body 6 is fixedly installed on one side of the lifting frame 5. Guide rods 7 are symmetrically fixedly installed on the top wall of the telescopic cylinder 4. Before use, the cutting machine body 6 and the telescopic cylinder 4 are connected to a power supply wire and a controller. The telescopic cylinder 4 is extended by the external controller, which drives the lifting frame 5 to move downward, thereby causing the cutting machine body 6 to move downward and cut the film roll.
[0024] Furthermore, the lifting assembly includes four plug-in columns 19, which are fixedly connected to the four corners of the top of the sliding block 21. A movable frame 16 is slidably connected to the top of the four plug-in columns 19. An adjusting screw 20 is rotatably connected to the middle of the top of the sliding block 21. The adjusting screw 20 and the movable frame 16 are threadedly connected. The sliding block 21 is penetrated by the drive screw 15 and the two are threadedly connected. After adjusting the distance between the two support rollers 9, the film roll is placed between the two support rollers 9. Then, according to the position of the film roll, the adjusting screw 20 is rotated so that the movable frame 16 slides on the four plug-in columns 19, thereby changing the position of the movable frame 16. At the same time, when it is necessary to change the position of the film roll, the drive screw 15 is rotated and screwed onto the sliding block 21 so that the sliding block 21 slides on the second support rod 14, which can perform continuous cutting of film rolls of different widths.
[0025] Furthermore, the internal support assembly includes a drive motor 17. Before use, the drive motor 17 is connected to a power supply wire and a controller. The drive motor 17 is fixedly installed on the side of the movable frame 16 away from the mounting frame 2. A drive shaft 18 is rotatably connected to the side of the movable frame 16 near the mounting frame 2. The drive shaft 18 and the output shaft of the drive motor 17 are connected in a transmission connection. Two fixed ring seats 23 are fixedly connected to one end of the drive shaft 18, and a sliding ring seat 24 is threaded to the other end of the drive shaft 18. Limit grooves 25 are symmetrically opened on the outer side of the drive shaft 18. Matching protrusions are opened on the inner wall of the sliding ring seat 24 to further ensure the stability of the sliding ring seat 24 when the drive shaft 18 rotates. The side of the mounting frame 2 near the movable frame 16 is threadedly connected to... The device includes a positioning nut 26, two fixing ring seats 23, and a sliding ring seat 24, each with a support arm 27 rotatably connected to its outer side. Each support arm 27 has an inner support block 28 rotatably connected to its top. When installing the film roll, the film roll mandrel is placed on the outside of the inner support block 28. Rotating the positioning nut 26 moves the sliding ring seat 24, causing the support arm 27 to drive the inner support block 28, which then presses against the inner wall of the film roll mandrel to support the film roll. After installation, the drive motor 17 rotates, driving the transmission shaft 18 to rotate, causing the fixing ring seat 23, sliding ring seat 24, limiting groove 25, positioning nut 26, support arm 27, and inner support block 28 to rotate, thus rotating the film roll. Cutting can then be performed.
[0026] Furthermore, the support assembly includes two first fixed vertical plates 8, which are symmetrically and movably connected inside the mounting frame 2. Each of the two first fixed vertical plates 8 is rotatably connected to a support roller 9, and a number of universal ball bearings 10 are rotatably connected to the outside of the support roller 9. When placing the film roll, the bidirectional screw 12 is rotated and engaged with the two first fixed vertical plates 8, so that the two first fixed vertical plates 8 can move closer or further apart from each other. The distance between the two first fixed vertical plates 8 can be adjusted according to the film rolls of different diameters, thereby changing the distance between the two support rollers 9. Then the film roll is placed between the two support rollers 9.
[0027] Furthermore, the drive assembly includes a bidirectional lead screw 12, which is inserted through one side of the mounting frame 2. A first support rod 11 is symmetrically mounted inside the mounting frame 2. The bidirectional lead screw 12 is threadedly connected to two first fixed vertical plates 8. The first support rod 11 passes through the two first fixed vertical plates 8. Adjusting wheels 22 are fixedly connected to the ends of both the bidirectional lead screw 12 and the drive lead screw 15.
[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
