Description

Technical Field

[0001] This utility model relates to the field of packaging film production technology, and in particular to a deviation correction mechanism for packaging film production. Background Technology

[0002] During the continuous production of packaging film, the film material is prone to lateral shift due to uneven tension, guide roller installation deviation, or equipment vibration. Traditional correction methods mainly rely on mechanical limits or photoelectric sensors in conjunction with servo motors to adjust the position of the guide rollers. Photoelectric correction systems require precision sensors and control systems, which are difficult to maintain and cannot be afforded by small and medium-sized enterprises. Rigid limit devices or rollers directly squeezing the film material can easily cause surface scratches or indentations, affecting the quality of the finished product. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deviation correction mechanism for packaging film production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A deviation correction mechanism for packaging film production includes a first mounting frame, a correction frame disposed at the middle of the upper surface of the first mounting frame, a second mounting frame slidably fitted at the bottom of the correction frame, a downward pressure frame slidably fitted on the second mounting frame, and a packaging film transfer mechanism disposed on the second mounting frame. The packaging film transfer mechanism includes servo electric cylinders, which are symmetrically mounted on the second mounting frame. Pressure plates are horizontally mounted at the bottom of the piston rods of the servo electric cylinders on both sides, and traceless adhesive tape is provided on the bottom surface of the pressure plates.

[0005] In addition, a preferred structure is that multiple packaging film transfer and pressing frames are evenly arranged on both sides of the correction frame on the upper surface of the mounting frame, and guide rollers are arranged on the upper surface of the mounting frame below the correction frame.

[0006] In addition, a preferred structure is that the top of the correction frame is provided with a slide rail, and sliders are symmetrically slidably fitted on the slide rail, with the sliders mounted on the second mounting frame.

[0007] In addition, a preferred structure is that the second mounting bracket has symmetrically vertically arranged sliding rods, the lower pressure bracket is slidably fitted on the sliding rods, and the bottom of each sliding rod is fitted with a spring, the bottom end of the spring abutting against the bottom plate of the sliding rod, and the top end of the spring abutting against the lower pressure bracket.

[0008] In addition, a preferred structure is that the lowering frame includes a sliding frame symmetrically slidingly fitted on the sliding rod, with lowering rods symmetrically arranged at the bottom of both sides of the sliding frame, a connecting plate connected to one side wall of the sliding frame, and a handle provided at one end of the connecting plate.

[0009] The beneficial effects of this utility model are as follows: This utility model uses the non-marking adhesive tape at the bottom of the pressure plate to adsorb the offset film material, avoiding scratches or indentations caused by mechanical hard contact, ensuring the integrity of the packaging film surface. It adopts manual mechanical adjustment such as sliders, slide rails, and handles, eliminating the need for expensive sensors and servo control systems, reducing manufacturing costs and maintenance difficulty. The lower pressure frame automatically resets through springs, and together with the lower pressure rod, it quickly separates the film material from the non-marking adhesive tape, ensuring that the film material falls smoothly back to the transmission station after correction.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Reference Figure 1-7 A deviation correction mechanism for packaging film production includes a first mounting frame 1. The first mounting frame 1 has a correction frame 3 located at the center of its upper surface. A second mounting frame 4 is slidably fitted to the bottom of the correction frame 3. A lower pressure frame 5 is vertically slidably fitted to the second mounting frame 4. A packaging film transfer mechanism 7 is mounted on the second mounting frame 4. The packaging film transfer mechanism 7 includes servo cylinders 71 symmetrically mounted on the second mounting frame 4. Pressure plates 72 are horizontally mounted at the bottom ends of the piston rods of the servo cylinders 71 on both sides. A traceless adhesive tape 73 is provided on the bottom surface of the pressure plate 72 for sticking the packaging film.

[0014] Among them, multiple packaging film transfer and pressing frames 2 are evenly arranged on both sides of the correction frame 3 on the upper surface of the first mounting frame 1, and guide rollers 6 are arranged on the upper surface of the first mounting frame 1 below the correction frame 3.

[0015] Furthermore, the top of the straightening frame 3 is provided with a slide rail 31, and a slider 32 is symmetrically slidably fitted on the slide rail 31. The slider 32 is installed on the second mounting frame 4. A slide rod 41 is symmetrically and vertically arranged on the second mounting frame 4. The lower pressure frame 5 is slidably fitted on the slide rod 41, and a spring 42 is sleeved on the bottom of each slide rod 41. The bottom end of the spring 42 abuts against the bottom plate of the slide rod 41, and the top end of the spring 42 abuts against the lower pressure frame 5. The spring 42 is used to realize the reset of the slide frame 51.

[0016] In addition, the lowering frame 5 includes a sliding frame 51 that is symmetrically slidably fitted on the sliding rod 41. Lowering rods 52 are symmetrically arranged at the bottom of both sides of the sliding frame 51. A connecting plate 53 is connected to one side wall of the sliding frame 51. A handle 54 is provided at one end of the connecting plate 53. The handle 54 is used for operation by the operator.

[0017] In this embodiment, when the packaging film is transferred on the production line via the packaging transfer pressing frame 2, the position of the packaging film changes due to the slippage of the guide roller 6. At this time, an offset correction mechanism is required. The packaging film transfer pressing frames 2 on both sides no longer hold the packaging film. The servo cylinder 71 is activated, causing its piston rod to extend. The non-marking adhesive tape 73 at the bottom of the pressure plate 72 can slightly adhere to the packaging film. The piston rod of the servo cylinder 71 retracts, thereby suspending the packaging film. Then, the operator can push the handle 54 to make the second mounting frame 4 move along the slider 32 on the slide rail 31, thereby correcting the overall position of the packaging film. After correction, the handle 54 drives the sliding frame 51 to slide downward on the slide rod 41. The spring 42 retracts, allowing the lower pressure rod 52 to contact the packaging film below, thereby causing it to fall off the non-marking adhesive tape 73 and resume the transfer process.

[0018] In this invention, the offset film material is adsorbed by the traceless adhesive tape 73 at the bottom of the pressure plate 72, avoiding scratches or indentations caused by mechanical hard contact and ensuring the integrity of the packaging film surface. Manual mechanical adjustment, such as the slider 32, slide rail 31, and handle 54, eliminates the need for expensive sensors and servo control systems, reducing manufacturing costs and maintenance difficulty. The lower pressure frame 5 automatically resets via spring 42, and, in conjunction with the lower pressure rod 52, quickly separates the film material from the traceless adhesive tape 73, ensuring the film material smoothly falls back to the transmission station after correction. The above description is only a preferred embodiment of this invention, but the scope of protection of this invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this invention, based on the technical solution and inventive concept of this invention, should be included within the scope of protection of this invention.
