Description

Technical Field

[0001] This utility model relates to the field of film processing equipment technology, and in particular to a dual-axis plus multi-axis winding and slitting machine. Background Technology

[0002] In modern industrial production, roll materials such as plastic film, paper, and metal foil are widely used in packaging, electronics, printing, and other industries. A slitting machine is the core equipment that cuts wide rolls of material into several narrow rolls according to process requirements. After slitting, the narrow rolls need to be rewound into rolls using a winding device.

[0003] Currently, slitting and winding equipment on the market is generally classified into different types based on the winding method. For example, some equipment uses a vertical winding system with upper and lower shafts adjacent to the slitting blade assembly. This structure is simple and compact, suitable for products with larger slitting widths and less stringent tension control requirements, offering a short process flow and high efficiency. Other equipment uses horizontal winding, especially horizontal multi-shaft winding equipped with magnetic slip shafts. This method can provide independent and precise tension control for multiple narrow-width rolls, making it particularly suitable for high-end products with small slitting widths, large winding diameters, and extremely high requirements for the flatness of the winding end face and tension stability.

[0004] However, existing technologies have the following drawbacks:

[0005] Limited functionality: Traditional equipment typically only has one winding function. If a manufacturing company needs to process different types of products, it must purchase two different types of slitting and winding machines, resulting in high equipment investment costs and large production space requirements.

[0006] Poor versatility: Single-function equipment cannot flexibly adapt to diverse production needs. When the specifications of ordered products (such as width, roll diameter, tension) vary greatly, existing equipment is difficult to meet them simultaneously, limiting the company's production flexibility and market competitiveness.

[0007] Therefore, how to design a slitting and rewinding device that is structurally integrated, fully functional, and capable of switching between multiple rewinding methods on a single device to adapt to different process requirements is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0008] The purpose of this invention is to provide a dual-axis plus multi-axis winding and slitting machine, which aims to solve the problems of single function, poor versatility and high cost of existing slitting and winding equipment.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A dual-axis plus multi-axis winding and slitting machine includes:

[0011] The slitting mechanism (1) includes an unwinding device (111) for unwinding, a slitting device (121) for cutting the film, and a sizing device (122) for arranging the slitting film.

[0012] A traction mechanism (2) is connected downstream of the material preparation device (122) and is used to pull the film output from the material preparation device (122);

[0013] and a winding mechanism (3), which is connected downstream of the traction mechanism (2).

[0014] Its key innovation lies in the fact that: the slitting mechanism (1) is also provided with at least one first winding device (123), which is used to selectively and directly wind up the film output from the material preparation device (122); the winding mechanism (3) includes at least one second winding device (31), which is used to wind up the film traction by the traction mechanism (2).

[0015] Through the above structure, this utility model realizes a dual-mode winding function. When processing materials with simple process requirements, the operator can choose to use the first winding device (123) set inside the slitting mechanism (1) for direct winding, which has a short path and high speed. When processing precision materials with high requirements for tension control and winding diameter, the first winding device (123) is not used. Instead, the film is allowed to continue forward, and precise tension is established and transmitted through an independent traction mechanism (2). Finally, the second winding device (31) in the winding mechanism (3) (such as horizontal slip shaft winding) performs high-quality winding. This dual-path design allows one device to have two mainstream winding modes, which greatly improves the versatility and multi-functionality of the equipment and reduces the equipment investment and site costs for enterprises.

[0016] As a preferred implementation scheme:

[0017] The slitting mechanism (1) includes a first functional section (11) and a second functional section (12) arranged symmetrically on the left and right sides, and a third functional section (13) disposed above the first functional section (11) and the second functional section (12). The unwinding device (111) is disposed in the first functional section (11), while the slitting device (121), the material straightening device (122), and the first winding device (123), which serves as a direct winding unit, are all integrated in the second functional section (12). This modular partitioned layout makes the equipment structure clear and facilitates manufacturing, installation, and maintenance.

[0018] The third functional unit (13) is equipped with a CCD camera (131) and a support roller (132). The CCD camera (131) is used to monitor the edge of the masterbatch or the printing line on the unwinding device (111) in real time, providing a signal to the correction system to ensure slitting accuracy. The support roller (132) provides stable support and guidance for the masterbatch before it enters the slitting station.

[0019] The traction mechanism (2) consists of multiple traction devices (21), each of which includes an upper and lower feed roller (211) and a lower and upper discharge roller (212), as well as a drive motor (213). As an independent tension control zone, the traction device (21) can provide stable and precise feed tension for subsequent horizontal winding, which is the key to ensuring high-quality winding.

[0020] The second winding device (31) is a horizontal differential winding structure, specifically including a winding arm (313), a magnetic differential shaft (311) at one end, and an air plug (314) at the other end. The magnetic differential shaft (311) is the core component for achieving precise tension control. It allows multiple winding rolls on the same shaft to wind independently with a small speed difference, thereby compensating for the effects of uneven material thickness and ensuring uniform tension in all sub-rolls. The air plug (314) is used for quick loading and unloading of the winding rolls (315).

[0021] To prevent the axial movement of the roll material caused by the increase in roll diameter during the winding process, the second winding device (31) is also provided with a material tray (312), which is located at one end of the winding arm (313) near the air expansion plug (314) to effectively block the winding roller (315) and ensure that the winding end face is flat.

[0022] The winding mechanism (3) also includes multiple guide wheel assemblies (32), each guide wheel assembly including a support frame (321) and a guide wheel (322). These guide wheels (322) are cleverly arranged between the traction mechanism (2) and each of the second winding devices (31), and are responsible for accurately and smoothly guiding the multiple narrow strips of film after slitting to their respective winding positions.

[0023] In order to correspond to the name "dual axis", the second functional unit (12) is preferably provided with two first winding devices (123) arranged vertically, which can realize dual axis vertical winding and further improve the production efficiency in the direct winding mode.

[0024] Specifically, the unwinding device (111) includes a pneumatic unwinding shaft (1111) and multiple unwinding rollers (1112) to facilitate the fixing and conveying of the masterbatch. The slitting device (121) adopts a combination of a blade holder (1211) and blades (1212), which has a simple and reliable structure. The material straightening device (122) includes a material straightening shaft and material straightening rollers driven by a motor, which are used to straighten and guide the material after slitting.

[0034] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0035] Example

[0036] Reference Figures 1 to 5 This utility model discloses a dual-axis plus multi-axis winding and slitting machine, the core of which is to provide two selectable material winding paths.

[0037] The equipment consists of three main components: a slitting mechanism (1), a traction mechanism (2), and a winding mechanism (3).

[0038] The slitting mechanism (1) is the front-end processing unit of the equipment. It is designed as a modular structure, comprising a first functional unit (11), a second functional unit (12), and a third functional unit (13). The first functional unit (11) and the second functional unit (12) are arranged symmetrically on the left and right, and the structure is stable; the third functional unit (13) is located above them.

[0039] In the first functional unit (11), an unwinding device (111) is provided. This device includes a pneumatic unwinding shaft (1111) for locking a wide roll of film masterbatch, and multiple unwinding rollers (1112) for guiding and conveying. After the masterbatch is unwound from the unwinding shaft (1111), it passes over an upper support roller (132), which is located in the third functional unit (13). At the same time, a CCD camera (131) in the third functional unit (13) is directly facing the film at the unwinding device (111) to detect the edge position of the film or printed marks, thereby achieving high-precision automatic deviation control.

[0040] The film then enters the second functional section (12). Here, it first passes through a slitting device (121), which consists of multiple cutter holders (1211) and blades (1212) fixed thereon, to precisely slit the wide film into multiple strips of the required narrow film. The slit film strips then enter a shaping device (122), which consists of a shaping motor, a shaping shaft, and shaping rollers, to shape the film so that it is flat and orderly before entering the next process.

[0041] One of the key features of this utility model is reflected in the subsequent design of the second functional unit (12). Within this functional unit, two vertically arranged first winding devices (123) are positioned immediately following the material preparation device (122). These two devices are typical vertical winding units. When the production task is suitable for direct winding, the operator can activate the first winding devices (123), and the slit film, after passing through the material preparation device (122), is directly wound up by these two upper and lower shafts, completing the winding operation. This path is "Mode 1: Dual-shaft direct winding".

[0042] When precision winding is required, the first winding device (123) is not used. After being drawn out from the forming device (122), the slit film enters an independent traction mechanism (2). This mechanism consists of multiple traction devices (21), each containing a feed roller (211) and an output roller (212), driven by a drive motor (213). The traction mechanism (2) establishes an independent tension zone between slitting and winding by precisely controlling the speed of the feed and output rollers, providing a stable prerequisite for subsequent high-quality winding.

[0043] After leaving the traction mechanism (2), the film enters the final winding mechanism (3). This path is "Mode 2: Multi-axis Precision Winding". The winding mechanism (3) mainly consists of multiple second winding devices (31) and guide wheel sets (32). The multiple film strips coming out of the traction mechanism (2) first pass through the guide wheel sets (32). Each guide wheel set consists of a support frame (321) and a rotatable guide wheel (322), and their function is to accurately guide the film strips at different positions to the corresponding second winding device (31).

[0044] The second winding device (31) is a horizontally mounted precision winding unit. It consists of a winding arm (313) as its main body, with a core component magnetic slip shaft (311) installed at one end and an air-filled plug (314) for fixing the winding roller (315) installed at the other end. The film is guided onto the winding roller (315) for winding. During the winding process, as the roll diameter increases, the magnetic slip shaft (311) allows for slight speed differences between the winding rollers, thereby ensuring that the tension of each roll of narrow-band film remains constant and uniform. At the same time, in order to prevent the winding roller (315) from axially moving during high-speed rotation and as the roll diameter increases, a material tray (312) is also installed at the end of the winding arm (313) near the air-filled plug (314), which effectively limits and blocks movement, ensuring that the winding end face is neat.

[0045] In summary, this utility model, by cleverly integrating a first winding device (123) within the slitting mechanism (1) and separately configuring an independent traction mechanism (2) and a second winding device (31), successfully achieves an organic combination of two functional modes on a single device: "vertical dual-axis direct winding" and "horizontal multi-axis slip differential precision winding." Users can flexibly select the working path according to different product requirements, thus making the equipment highly versatile, multifunctional, and economical.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
