[0003] Existing winding devices require deviation correction when winding food packaging film. Deviation during winding leads to irregularities, reducing production quality and increasing the defect rate. Furthermore, due to the varying sizes of the winding drums, workers must replace the winding rollers according to the drum size during disassembly and assembly, a time-consuming and labor-intensive operation. Therefore, to solve these problems, we need to design a food packaging film winding flatness correction device. Utility Model Content:

[0010] In a preferred embodiment of the food packaging film winding flatness correction device of this utility model, the pressing assembly includes a cylinder, a lifting plate, a slide rod, a spring, a connecting block, and a pressing roller. A top plate is fixedly connected to the top of the side plate, the cylinder is fixedly connected to the top plate, the lifting plate is fixedly connected to the cylinder, the slide rod is fixedly connected to the connecting block, both sides of the pressing roller are rotatably connected to the connecting block, one end of the spring is fixedly connected to the connecting block, the other end of the spring is fixedly connected to the bottom of the lifting plate, the slide rod is slidably connected to the lifting plate, and a limit plate is fixedly connected to the top of the slide rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this device, the second motor operates to rotate the lead screw. Since the lead screw is a bidirectional lead screw and the slider is threadedly connected to the lead screw, the slider slides in the adjustment groove. When the lead screw rotates, the sliders on both sides of the lead screw move towards the middle, which allows the joint to drive the movable strip to move outward in the movable groove. This allows the annular plate on the movable strip to clamp and fix the winding drum, thus facilitating the operation of the first motor and causing the winding roller to drive the winding drum to rotate, which is convenient for winding the food packaging film. Furthermore, when it is necessary to correct the packaging film during the winding process, the electric push rod operates to extend and retract the movable rod under the action of the electric push rod. This allows the correction roller on the movable rod to be adjusted left and right, which is convenient for correcting the food packaging film. At the same time, the cylinder operates to press the packaging film wound on the winding drum, which enhances the flatness of the packaging film when the device winds it up and avoids wrinkles during winding, thus affecting the winding effect.

In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Please see Figures 1-4 This utility model provides a device for correcting the flatness of food packaging film roll-up, comprising:

[0023] The base plate 101 is provided with a winding assembly 110, a clamping assembly 120 is provided on the winding assembly 110, a pressing assembly 130 is provided on the base plate 101, and a correction assembly 140 is provided on the base plate 101.

[0024] Specifically, the clamping component 120 can clamp and fix winding drums 110c of different sizes, facilitating the winding operation of the winding component 110; the alignment component 140 can perform alignment work when the winding component 110 is winding the packaging film, improving the practicality of the device and reducing the possibility of wrinkles; the pressing component 130 allows the device to press the winding packaging film when it is winding, facilitating the flattening of the wound packaging film and increasing the flatness during winding.

[0025] Please see Figures 1-3The winding assembly 110 includes a first motor 110a, a winding roller 110b, and a winding drum 110c. A side plate 101a is fixedly connected to one side of the base plate 101. The first motor 110a is fixedly connected to the side plate 101a. The winding roller 110b is fixedly connected to the first motor 110a. The winding drum 110c is movably connected to the winding roller 110b. The clamping assembly 120 includes a second motor 120a, a lead screw 120b, a slider 120c, a movable bar 120d, a joint 120e, and an annular plate 120f. The second motor 120a is fixedly connected to the take-up roller 110b, the lead screw 120b is fixedly connected to the second motor 120a, the slider 120c is threadedly connected to the lead screw 120b, one end of the joint 120e is rotatably connected to the slider 120c, and the other end of the joint 120e is rotatably connected to one side of the inner groove of the movable bar 120d. The annular plate 120f is fixedly connected to the other side of the movable bar 120d. The take-up roller 110b has an adjustment groove 110d, and the adjustment groove 110d has a movable groove 110e. The lead screw 120b is rotatably connected to the adjustment groove 110d, the slider 120c is slidably connected to the adjustment groove 110d, and the movable bar 120d is slidably connected to the movable groove 110e.

[0026] Specifically, the second motor 120a inside the take-up roller 110b operates, causing the lead screw 120b to rotate. Since the slider 120c is threadedly connected to the lead screw 120b, and the slider 120c is limited by the adjusting groove 110d, it slides within the adjusting groove 110d. When the lead screw 120b rotates, it drives the slider 120c to move, causing the joint 120e to move. This allows the movable strip 120d to move within the movable groove 110e, thereby allowing the lead screw 120b to rotate. The annular plate 120f on the movable strip 120d clamps and fixes the inner wall of the take-up drum 110c. When the first motor 110a works, the take-up roller 110b drives the take-up drum 110c to rotate, which facilitates the winding of the food packaging film. Furthermore, since the lead screw 120b is a bidirectional lead screw, the sliders 120c on both sides of the lead screw 120b can move simultaneously toward the middle of the lead screw 120b, improving the clamping effect of the movable strip 120d and the annular plate 120f on the take-up drum 110c.

[0027] Please see Figures 1-4The pressing assembly 130 includes a cylinder 130a, a lifting plate 130b, a slide rod 130c, a spring 130d, a connecting block 130e, and a pressing roller 130f. The top plate 101b is fixedly connected to the top of the side plate 101a. The cylinder 130a is fixedly connected to the top plate 101b. The lifting plate 130b is fixedly connected to the cylinder 130a. The slide rod 130c is fixedly connected to the connecting block 130e. The two sides of the pressing roller 130f are rotatably connected to the connecting block 130e. One end of the spring 130d is fixedly connected to the connecting block 130e, and the other end of the spring 130d is fixedly connected to the bottom of the lifting plate 130b. The slide rod 130c is slidably connected to the lifting plate 130b, and a limit plate 130g is fixedly connected to the top of the slide rod 130c.

[0028] Specifically, when the winding drum 110c is winding, the pressing roller 130f can press the food packaging film being wound to prevent wrinkles from forming during winding and affecting the winding effect. At the same time, when a certain thickness is wound, the slide bar 130c can be moved, and through the force of the spring 130d, the pressing roller 130f can increase the pressing effect on the food packaging film being wound on the winding drum 110c, preventing wrinkles from forming during winding and affecting the subsequent winding effect. Furthermore, the position and height of the pressing roller 130f can be adjusted by the cylinder 130a, which facilitates the winding and pressing of winding drums 110c of different thicknesses and the wound food packaging film.

[0029] Please see Figures 1-2 The correction assembly 140 includes an electric push rod 140a, a movable rod 140b, a correction roller 140c, and a limiting ring 140d. The electric push rod 140a is fixedly connected to one side plate 101a. One end of the electric push rod 140a is fixedly connected to the movable rod 140b, and the other end of the movable rod 140b is fixedly connected to the limiting ring 140d. The correction roller 140c is rotatably connected to the movable rod 140b, and the other side of the movable rod 140b is slidably connected to another side plate 101a.

[0030] Specifically, when it is necessary to correct the flatness of the rolled food packaging film, the electric push rod 140a is operated, which allows the movable rod 140b to move on the side plate 101a, thereby driving the correction roller 140c to adjust its left and right position. This causes the food packaging film on the correction roller 140c to move, making it easier for the take-up roller 110b to drive the take-up drum 110c to perform the take-up operation, thus avoiding problems such as wrinkles in the food packaging film during take-up. Furthermore, the limiting ring 140d can prevent the movable rod 140b from leaving the side plate 101a when the electric push rod 140a retracts too much, which would affect the use of the device.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
