Description

Technical Field

[0001] This utility model relates to the technical field of film winding devices, specifically a PE film assisted winding device. Background Technology

[0002] PE stretch film (also known as PVC stretch film) is a type of plastic film mainly made from a mixture of several different grades of polyethylene resin through extrusion. It is self-adhesive and can be single-sided (cast) or double-sided (blow-molded). It can be stretched and tightly wrapped around items, and its self-adhesive does not adhere to the surface of the wrapped item, but only exists between the film layers. The production process of PE stretch film involves winding and rolling to collect the film for easy preparation into rolls for sale.

[0003] The utility model with announcement number CN219839241U discloses a PE stretch film winding device. This utility model, by setting a linear guide box, a servo motor, a threaded column, a sliding block and a second vertical plate, can more conveniently change the distance between the second vertical plate and the first vertical plate, thereby conveniently fitting the PE stretch film winding cylinder onto the outer surface of the two rotating insert columns, and conveniently removing the PE stretch film winding cylinder after winding.

[0004] In the above-mentioned device, the winding drum is fixedly installed by inserting a rotating insert post into both ends of the winding drum. However, this installation method has certain problems. First, it can only fix a specific winding drum that matches the size of the rotating insert post, and its applicability is extremely narrow. If the device is to be applicable to winding drums of other sizes, the rotating insert post needs to be disassembled and replaced with the corresponding size. In the above-mentioned device, replacing the rotating insert post is a rather cumbersome operation. There are many structures that are connected to it, which makes the replacement work very cumbersome and inconvenient, and also limits the applicability of the device to a certain extent. Therefore, in order to address the above problems, a PE film assisted winding device is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a PE film auxiliary winding device. This film winding device clamps and fixes the winding drum by inserting a conical clamping mechanism into both ends of the winding drum. The conical clamping mechanism is conical and can adapt to winding drums of various diameters within a certain range. The distance between the two conical clamping mechanisms is adjustable, so it can also adapt to the fixing of winding drums of different lengths. In addition, the conical clamping drum and the rotating shaft are detachably connected by a plug-in connection, so it is convenient to replace conical clamping drums of different sizes, which can further broaden the clamping range of the conical clamping mechanism and make the winding device more widely applicable. This solves the technical problem of the poor applicability of the rotating insertion column in the comparative technology, which can only fix specific winding drums of a certain size and is inconvenient to replace, thus leading to poor applicability.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A PE film auxiliary winding device includes a base plate with a fixed support frame fixed on one side of its upper surface and an installation groove on the other side, wherein a movable support frame is slidably arranged; a conical clamping mechanism is rotatably mounted on top of the fixed and movable support frames; and an adjusting guide rail is set on the base plate, wherein an adjustable film guiding mechanism is slidably arranged. The conical clamping mechanism includes a rotating shaft with a conical clamp detachably mounted at its front end. The surface of the conical clamp has several anti-slip grooves arranged in a circumferential array. The film winding device clamps and fixes the winding drum by inserting the conical clamp into both ends of the winding drum. Because of its conical shape, it can adapt to winding drums of various diameters within a certain range, and the spacing of the conical clamps is adjustable, which can also adapt to the fixing of winding drums of different lengths. In addition, the conical clamp and the rotating shaft are detachably connected by a plug-in connection, so different sizes of conical clamps can be easily replaced, which can further broaden the clamping range of the conical clamping mechanism and make the winding device more widely applicable.

[0008] In one possible implementation, an end piece is fixedly provided at the front end of the rotating shaft, and a rib is fixedly provided on it. The conical clamp has an insertion groove corresponding to the rib. Based on the above structure, the conical clamp can be fixedly installed by simply aligning the insertion groove with the rib and fitting it on the sleeve through friction, which is very convenient for disassembly and assembly.

[0009] In one possible implementation, the adjustable film guiding mechanism includes a sliding plate seat with a film support roller at the center of its upper end face and guide rods on both sides of the sliding plate seat. A sliding seat is installed therein, and several anti-deviation rollers are installed on the upper end face of the sliding seat. When the film is wound up, the film support roller lifts the middle part of the film to keep it in a taut and flat state, while the anti-deviation rollers can abut against the sides of the film to prevent it from deviating during operation. In addition, since the spacing between the anti-deviation rollers is adjustable, it can match film with different widths and has strong applicability.

[0010] In one possible implementation, threaded adjusting rods are installed on both sides of the sliding plate seat, which are threadedly connected to the sliding seat. When the threaded adjusting rods are turned, they drive the sliding seat connected to them to move along the guide rod, thereby adjusting the position of the anti-deviation roller so that it can match films of different widths and has strong applicability.

[0011] In one possible implementation, the adjusting guide rail includes a guide rail plate with a mating groove. The sliding plate seat has several locking screws on both sides, which are slidably disposed in the mating groove and threaded with locking wheels. Based on the above structure, the adjustable film guiding mechanism and the adjusting guide rail can be slidably connected, which facilitates the adjustment of the position of the adjustable film guiding mechanism and ensures that it can be aligned with the winding drum. After the position of the adjustable film guiding mechanism is adjusted, tightening the locking wheels can fix its position through friction.

[0012] In one possible implementation, a rotation drive mechanism is provided on the lower side of the fixed support frame, which includes a drive motor. The output shaft of the drive motor is fixedly connected to a drive wheel, and a driven wheel is fixedly provided on the corresponding rotation shaft. The drive wheel and the driven wheel are connected by a transmission belt. When the drive motor is working, it can drive the drive wheel to rotate and drive the driven wheel to rotate through the transmission belt, thereby driving the conical clamping mechanism on the fixed support frame to rotate, and driving the winding drum it clamps to rotate to complete the automatic winding and rewinding work.

[0013] In one possible implementation, the lower side of the movable support frame is provided with a screw adjustment mechanism, which includes a mounting guide rail, wherein a sliding table fixedly connected to the movable support frame is slidably disposed therein, and a rotatable drive screw is provided in the mounting guide rail, which is threadedly connected to the sliding table. When the drive screw is turned, it can drive the sliding table to slide, thereby moving the movable support frame connected thereto, thereby realizing the adjustment of the spacing of the conical clamping mechanism.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] The film winding device clamps and fixes the winding drum by inserting a conical clamping mechanism into both ends of the winding drum. The conical clamping mechanism is conical and can adapt to winding drums of various diameters within a certain range. The distance between the two conical clamping mechanisms is adjustable, so it can also adapt to the fixing of winding drums of different lengths.

[0016] Furthermore, in the conical clamping mechanism, the conical clamp and the rotating shaft are detachably connected by a plug-in connection, which allows for easy replacement of conical clamps of different sizes, further expanding the clamping range of the conical clamping mechanism and making the winding device more widely applicable.

Detailed Implementation

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0025] like Figure 1 - Figure 3 As shown, this embodiment provides a PE film auxiliary winding device, including a base plate 1, a fixed support frame 2 fixedly mounted on one side of its upper end face, and an installation groove 11 opened on the other side, wherein a movable support frame 3 is slidably arranged, a conical clamping mechanism 4 is rotatably mounted on the top of the fixed support frame 2 and the movable support frame 3, an adjusting guide rail 5 is set on the base plate 1, and an adjustable film guiding mechanism 6 is slidably arranged therein, wherein the conical clamping mechanism 4 includes a rotating shaft 41, and a conical clamping cylinder 44 is detachably mounted on its front end, and a plurality of anti-slip grooves 45 arranged in a circumferential array are opened on the surface of the conical clamping cylinder 44. The film winding device clamps and fixes the winding cylinder by inserting the conical clamping cylinder 44 into both ends of the winding cylinder. Because it is conical, it can adapt to winding cylinders of various diameters within a certain range, and the spacing of the conical clamping cylinders 44 is adjustable, which can also adapt to the fixing of winding cylinders of different lengths.

[0026] The rotating shaft 41 has an end piece 42 fixedly installed at its front end, and a rib 43 fixedly installed on it. The conical clamp 44 has a corresponding insertion groove 46 inside. Based on the above structure, the conical clamp 44 can be fixedly installed by simply aligning the insertion groove 46 with the rib 43 during installation and using friction. This makes it very easy to install and remove.

[0027] like Figure 5 As shown, the adjustable film guiding mechanism 6 includes a sliding plate base 61, with a film support roller 62 located in the center of its upper end face. Guide rods 63 are located on both sides of the sliding plate base 61, and a sliding seat 64 is slidably connected therein. Several anti-deviation rollers 65 are installed on the upper end face of the sliding seat 64. When winding the film, the film support roller 62 lifts the center of the film, keeping it in a taut and flat state, while the anti-deviation rollers 65 abut against both sides of the film to prevent it from shifting during operation. In addition, since the spacing between the anti-deviation rollers 65 is adjustable, it can match film of different widths, thus having strong applicability. Furthermore, threaded adjusting rods 66 are rotatably connected to both sides of the sliding plate base 61, which are threadedly connected to the sliding seat 64. When the threaded adjusting rods 66 are turned, they drive the sliding seat 64, which is threadedly connected to them, to move along the guide rods 63, thereby adjusting the position of the anti-deviation rollers 65 to match film of different widths, thus having strong applicability.

[0028] like Figure 4As shown, the adjusting guide rail 5 includes a guide rail plate 51 with a mating groove 52. Several locking screws 53 are provided on both sides of the sliding plate seat 61, which are slidably disposed in the mating groove 52 and threadedly connected to a locking wheel 54. Based on the above structure, the adjustable film guiding mechanism 6 and the adjusting guide rail 5 can be slidably connected, which facilitates the adjustment of the position of the adjustable film guiding mechanism 6 and ensures that it can be aligned with the winding drum. After the position of the adjustable film guiding mechanism 6 is adjusted, tightening the locking wheel 54 can fix its position through friction.

[0029] A rotation drive mechanism 7 is provided on the lower side of the fixed support frame 2. This mechanism includes a drive motor 71, with a drive wheel 72 fixedly connected to the output shaft of the drive motor 71. A driven wheel 73 is fixedly mounted on the corresponding rotation shaft 41. The drive wheel 72 and the driven wheel 73 are connected by a transmission belt 74. When the drive motor 71 operates, it drives the drive wheel 72 to rotate, and through the transmission belt 74, drives the driven wheel 73 to rotate. This drives the conical clamping mechanism 4 on the fixed support frame 2 to rotate, thereby rotating the winding drum it clamps to complete the automatic winding and take-up operation. Specifically, as shown... Figure 2 As shown.

[0030] like Figure 3 As shown, the movable support frame 3 is provided with a screw adjustment mechanism 8 on its lower side, which includes a mounting guide rail 81, in which a sliding table 82 fixedly connected to the movable support frame 3 is slidably arranged. The mounting guide rail 81 is provided with a rotatable drive screw 83, which is threadedly connected to the sliding table 82. When the drive screw 83 is turned, it can drive the sliding table 82 to slide, thereby moving the movable support frame 3 connected to it, thereby realizing the adjustment of the spacing of the conical clamping mechanism 4.

[0031] The working principle and usage process of this utility model:

[0032] The film winding device clamps and fixes the winding drum by inserting the conical clamping mechanism 4 into both ends of the winding drum. The conical clamping mechanism 4 is conical and can adapt to winding drums of various diameters within a certain range. The distance between the two conical clamping mechanisms 4 is adjustable, so it can also adapt to the fixing of winding drums of different lengths. Specifically, when the drive screw 83 is turned, it can drive the sliding table 82 to slide, and then the movable support frame 3 connected to it moves, thereby realizing the adjustment of the distance between the conical clamping mechanisms 4.

[0033] Furthermore, in the conical clamping mechanism 4, the conical clamp 44 and the rotating shaft 41 are detachably connected by a plug-in connection, thus allowing for easy replacement of conical clamps 44 of different sizes. This further expands the clamping range of the conical clamping mechanism 4, making the winding device more widely applicable. Specifically, when installing the conical clamp 44, it is only necessary to align the plug groove 46 with the rib 43 and put it on, and the conical clamp 44 can be fixedly installed through friction, which is very convenient for disassembly and assembly.

[0034] When winding the film, the film support roller 62 lifts the middle of the film to keep it taut and flat, while the anti-deviation roller 65 holds the sides of the film to prevent it from shifting during operation. When the threaded adjusting rod 66 is turned, it drives the sliding seat 64 connected to it to move along the guide rod 63, thereby adjusting the position of the anti-deviation roller 65 so that it can match film of different widths and has strong applicability.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
