[0001] This utility model relates to the field of turning equipment technology, and in particular to an anti-derailment turning machine for plastic film used in packaging bag production. Background Technology

[0002] In the packaging bag production process, the rewinding of plastic film is a crucial step, directly affecting the efficiency of subsequent bag-making processes and product quality. Currently, the industry commonly uses rewinding machines to perform operations such as unwinding, guiding, rewinding, and recycling of plastic film. Its core function is to transfer the film from its original roll state to the winding component through a transmission and guiding mechanism, forming a regular roll structure that facilitates storage, transportation, and downstream processing.

[0003] Existing film rewinding equipment has some problems in practical applications: when the film is running or the tension fluctuates, it is easy to deviate laterally due to insufficient limiting of the guiding mechanism, resulting in derailment, film wrinkles, tears, or even shutdown for adjustment, affecting the continuity of production.

[0004] To address these issues, those skilled in the art have proposed an anti-derailment rewinding machine for plastic film used in packaging bag production. Utility Model Content

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment provides an anti-derailment turning machine for plastic film used in packaging bag production, which can constrain the movement trajectory of the film and prevent the film from derailing. It includes a base plate 100. An unwinding guide mechanism 200, a rewinding mechanism 300, and a recycling mechanism 400 are sequentially arranged on the base plate 100 along the plastic film conveying direction; The unwinding guide mechanism 200 includes a mounting frame 201 and connecting plates 202 disposed on both sides of the mounting frame 201. The mounting frame 201 has a rail 204 installed on both sides of its inner wall. The connecting plates 202 are provided with two sets of guide rollers 205. A gap is left between the upper and lower sets of guide rollers 205 for the film to pass through. The unwinding assembly 206 is installed inside the connecting plate 202 near the front end.

[0029] The unwinding assembly 206 releases the plastic film, which passes through the gap between the upper and lower guide rollers 205 in the unwinding guide mechanism 200. The guide rail 204 and the guide rollers 205 limit the film's movement. Together with the support and guidance of the guide rollers 205, the film's movement trajectory is constrained, preventing it from deviating during transport. Subsequently, the film is transported to the rewinding mechanism 300 for rewinding. The rewinding film is then wound up by the recycling mechanism 400. Through the cooperation of various components, the movement trajectory of the film is effectively constrained, preventing the film from derailing.

[0030] Specifically, one end of each of the two connecting plates 202 has a slot 203, and the unwinding assembly 206 is installed inside the slot 203.

[0031] The unwinding assembly 206 is fixed inside the slot 203. When disassembly is required, the unwinding assembly 206 can be loosened and removed to facilitate the application of film.

[0032] Furthermore, the unwinding assembly 206 includes an unwinding motor 2061, a drive shaft 2062, an unwinding drum 2063, a coupling 2064, and a bushing 2065. The unwinding motor 2061 is mounted on the connecting plate 202. One end of the drive shaft 2062 is connected to the output shaft of the unwinding motor 2061 through the coupling 2064, and the other end is connected to the unwinding drum 2063 through the bushing 2065. The unwinding motor 2061 drives the drive shaft 2062 to rotate the unwinding drum 2063 to achieve unwinding. The bushing 2065 is mounted on the outside of the connecting plate 202, and the drive shaft 2062 is engaged inside the slot 203.

[0033] In use, after the film is placed on the unwinding drum 2063, the unwinding assembly 206 is fixed in the slot 203. The unwinding motor 2061 is started, and the transmission shaft 2062 is driven to rotate through the coupling 2064. The transmission shaft 2062 then drives the unwinding drum 2063 to rotate through the bushing 2065 to achieve unwinding. After passing through the guide roller 205 and the rail 204, the film is conveyed to the turning mechanism 300. After being straightened and tightened by the turning mechanism 300, the film is orderly wound onto the recycling mechanism 400.

[0034] Example 2

[0035] Reference Figures 1 to 4This is the second embodiment of the present invention. Unlike the previous embodiment, the turning mechanism 300 includes a fixed frame 301, a housing 302 and turning components. The fixed frame 301 is installed on the surface of the base plate 100, the housing 302 is installed on one side of the outer wall of the fixed frame 301, and there are multiple turning components, which are distributed alternately inside the housing 302 and the fixed frame 301.

[0036] The initial film is stretched and tightened by the flipping assembly, reducing wrinkles and ensuring uniform tension and tight, regular winding during the flipping and rewinding process, thereby improving the quality of the finished roll.

[0037] Specifically, the turning assembly includes a turning motor 303 and a shaft fixing seat 306. The turning motor 303 is installed inside the housing 302, and the shaft fixing seat 306 is installed on the inner wall of the fixing frame 301 on the side away from the housing 302. One end of the output shaft of the turning motor 303 is equipped with a connecting shaft 304, and the other end of the connecting shaft 304 is installed inside the shaft fixing seat 306. A turning drum 305 is sleeved on the outer circumference of the connecting shaft 304.

[0038] Furthermore, the turning drum 305 and the connecting shaft 304 are detachably connected, and the outer wall of the turning drum 305 is provided with anti-slip texture.

[0039] The anti-slip texture on the outer wall of the roll drum enhances the friction with the film. The roll drum stretches and tightens the film before winding it onto the take-up drum. The film is transferred from its original roll state to the take-up component through the transmission and guiding mechanism, forming a regular roll structure.

[0040] Example 3

[0041] Reference Figures 1 to 4 This is the third embodiment of the present invention. Unlike the previous embodiment, the recycling mechanism 400 includes a winding assembly and two connecting frames 401. The two connecting frames 401 are respectively installed at both ends of the tail of the fixed frame 301. One end of each of the two connecting frames 401 has a slot 402, and the winding assembly is engaged inside the slot 402.

[0042] The winding assembly is fixed in slot 2 402. After the film is completely wound up, the winding assembly can be taken out from slot 2 402, and then the wound film can be taken out.

[0043] Specifically, the winding assembly includes a winding motor 403, which is mounted on one side of the outer wall of the connecting frame 401. A second coupling 406 is mounted on one end of the winding motor 403, a horizontal shaft 404 is mounted on one end of the second coupling 406, a second bushing 407 is mounted on one end of the horizontal shaft 404, and one end of the second bushing 407 is fitted and fixed to the outer wall of the connecting frame 401. A winding drum 405 is fixedly mounted on the circumferential outer wall of the horizontal shaft 404.

[0044] Furthermore, the take-up drum 405 and the horizontal shaft 404 are connected by a keyway, and the length of the take-up drum 405 is adapted to the length of the flip drum 305.

[0045] Among them, coupling 1 2064 and coupling 2 406 are both flexible couplings, which will buffer vibration during transmission to ensure transmission stability.

[0046] In use, both coupling 2064 and coupling 406 are flexible couplings, which can buffer transmission vibration and prevent loosening or lag between the drive component and the roll. After being wound up by the winding assembly, the film is transferred from the original roll state to the winding component through the transmission and guiding mechanism to form a regular roll structure, which is convenient for storage, transportation and downstream processing.

[0047] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
