Description

Technical Field

[0001] This utility model relates to the field of film wrapping machine technology, specifically a film wrapping machine that can flatten the film. Background Technology

[0002] Film wrapping machines, also known as wrapping machines, are widely used in foreign trade exports, food and beverage production, canning, papermaking, dyeing and other products to meet the packaging requirements of containerized storage, transportation and mechanized loading and unloading operations. They help reduce the cost of containerized products, improve production efficiency, prevent damage to goods during handling, and provide dustproof, moisture-proof and cleanliness protection.

[0003] The existing Chinese utility model patent with publication number CN220721481U discloses a film wrapping machine, including a chassis, a loading tray rotatably connected to the chassis, a drive motor mounted on the chassis, and a wrapping assembly. A turntable rotatably rotates around the outer periphery of the loading tray on the chassis. The wrapping assembly is disposed on the turntable and located on the outer periphery of the loading tray. A linkage assembly is connected between the drive motor, the loading tray, and the turntable to drive the turntable and the loading tray to rotate coaxially and in opposite directions. This utility model has the following advantages and effects: the film wrapping machine has higher wrapping efficiency, longer service life, and convenient operation.

[0004] In the aforementioned film wrapping machine, by installing an adjusting component on the film frame, the problem of low efficiency in traditional film wrapping machines that drive the tray to rotate in one direction when wrapping thicker films or wrapping large items has been successfully solved. However, currently available film wrapping machines are still prone to film folding and deformation during the wrapping process. When the film folds and deforms, as the film continues to wrap, the folded and deformed film will be rolled into the film roll. Under the pressure of wrapping and winding, prolonged compression will cause damage and deformation to the film. This not only affects the efficiency of the wrapping process but may also lead to poor wrapping effect, thus affecting the final wrapping effect. Utility Model Content

[0005] The purpose of this invention is to overcome the problem that existing technologies are not convenient for flattening the film, thus affecting the winding effect, and to provide a film winding machine that can flatten the film.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A film wrapping machine capable of flattening a film includes:

[0008] A support frame has two rubber rollers rotatably connected to its inner two sides. A support plate is fixedly installed at the bottom of one side of the support frame, and a rotating disk is rotatably connected to the top center of the support plate. An air shaft is fixedly installed on the top of the rotating disk, and a film roller is clamped and connected to the outside of the air shaft. Two mounting shafts are rotatably connected to the other side of the support frame. A support block is rotatably connected to one side of the mounting shaft, and a flattening roller is rotatably connected to one side of the support block. The flattening roller has a structure that is thicker in the middle and thinner at both sides. Two baffles are fixedly installed on both sides of the flattening roller. A support spring is fixedly installed on one side of the support block, and a mounting block is fixedly installed on one side of the support spring.

[0009] In a preferred embodiment, a lifting groove is fixedly installed on the top of one side of the support frame, and a lifting block is slidably connected inside the lifting groove. The lifting block is a structure for moving up and down inside the lifting groove.

[0010] In a preferred embodiment, the top of the lifting block is rotatably connected to a connecting shaft, and one side of the connecting shaft is rotatably connected to a connecting plate, the connecting plate being a structure for connection.

[0011] In a preferred embodiment, an annular shaft is rotatably connected to one side of the connecting plate, the annular shaft being a structure for supporting the top of the air shaft.

[0012] In a preferred embodiment, a lifting plate is fixedly installed on one side of the support frame, and an electric lifting frame is slidably connected to the outside of the lifting plate. The electric lifting frame is a structure used to drive the lifting plate to move up and down inside it.

[0013] In a preferred embodiment, a base plate is fixedly installed at the bottom of the electric lifting frame, and a rotating seat is rotatably connected to the top of the base plate. The rotating seat is a structure used to drive the support seat to rotate.

[0014] In a preferred embodiment, a support base is rotatably connected to the top of the rotating seat, the support base being a structure for supporting the article.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In the film wrapping machine that can flatten the film, the use of flattening rollers to effectively support the film during the film processing is crucial. These flattening rollers are designed with a thicker middle section and relatively thinner ends. This shape helps to evenly support the film and prevent unnecessary folds or wrinkles during processing. To further optimize the flatness of the film, the support springs are designed to extend and contract accordingly when stretched or compressed. This elasticity allows the support blocks mounted on the rotating shaft to be flexibly angled. By adjusting the angle of the flattening rollers, the tension applied to the film can be precisely controlled to ensure that the film remains straight during the wrapping process. This mechanism of straightening and flattening the film significantly improves the packaging effect of the film wrapping machine, making the final product packaging neater and more beautiful, while also improving the efficiency and reliability of the packaging process.

[0017] 2. This film wrapping machine that can flatten the film effectively supports the film roller by using an air shaft. The downward movement of the lifting block inside the lifting groove and the rotation mechanism of the connecting shaft achieve support of the top of the air shaft by the annular rotating shaft. Furthermore, the rotation of the rotating disk drives the film roller to perform continuous rotation. This design significantly improves the support effect and overall stability of the film wrapping machine that can flatten the film, ensuring a smooth and efficient wrapping process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Combined with appendix Figure 1-4 In this embodiment, a film wrapping machine capable of flattening film includes: a support frame 1, with two rubber rollers 11 rotatably connected to the inner two sides of the support frame 1, a support plate 12 fixedly installed at the bottom of one side of the support frame 1, a rotating disk 13 rotatably connected to the top center of the support plate 12, an air shaft 14 fixedly installed at the top of the rotating disk 13, a film roller 15 clamped and connected to the outer side of the air shaft 14, two mounting shafts 16 rotatably connected to the other two sides of the support frame 1, a support block 17 rotatably connected to one side of the mounting shaft 16, a flattening roller 18 rotatably connected to one side of the support block 17, the flattening roller 18 having a structure that is thick in the middle and thin at both sides, two baffles 19 fixedly installed on both sides of the flattening roller 18, a support spring 110 fixedly installed on one side of the support block 17, and a mounting block 111 fixedly installed on one side of the support spring 110.

[0025] Specifically, the operation of the air shaft 14 effectively fixes the film roller 15, ensuring its stability and safety. Meanwhile, inside the support frame 1, two rubber rollers 11 play a crucial role, precisely guiding and supporting the film to ensure it remains flat during transport. Furthermore, with the assistance of the flattening roller 18, the film is further flattened, thus guaranteeing the quality and performance of the film. To accommodate films of different thicknesses and materials, the support spring 110 is designed to extend and contract appropriately. This elastic mechanism allows the mounting shaft 16 to drive the support block 17 for flexible angle adjustment. This adjustment mechanism not only improves the straightening effect of the film but also ensures that the film achieves optimal flatness after passing through the entire device.

[0026] A lifting groove 2 is fixedly installed on the top of one side of the support frame 1. A lifting block 21 is slidably connected inside the lifting groove 2. A connecting shaft 22 is rotatably connected to the top of the lifting block 21. A connecting plate 23 is rotatably connected to one side of the connecting shaft 22. An annular shaft 24 is rotatably connected to one side of the connecting plate 23.

[0027] Specifically, by moving the lifting block 21 downwards inside the lifting groove 2, it is ensured that the lifting block 21 can reach the designated position smoothly and accurately. At the same time, the descent of the lifting block 21 is closely coordinated with the operation of the connecting shaft 22. The rotation of the shaft drives the connecting plate 23 to rotate accordingly. This linkage mechanism design allows the annular shaft 24 to effectively apply support force to the top of the air shaft 14, thereby providing auxiliary support for the film roller 15. This support method significantly improves the stability of the film winding machine when winding film, ensuring the smoothness and efficiency of the film winding process, thereby improving the performance and reliability of the entire equipment.

[0028] A lifting plate 3 is fixedly installed on one side of the support frame 1. An electric lifting frame 31 is slidably connected to the outside of the lifting plate 3. A base plate 32 is fixedly installed at the bottom of the electric lifting frame 31. A rotating seat 33 is rotatably connected to the top of the base plate 32. A support seat 34 is rotatably connected to the top of the rotating seat 33.

[0029] Specifically, the operation of the electric lifting frame 31, driven by electricity, moves the lifting plate 3 up and down within it, thereby adjusting the height of the lifting plate to meet different usage needs. Simultaneously, the base plate 32 supports the bottom of the film wrapping machine, ensuring its stability and reliability. The base plate 32 is designed with load-bearing capacity and stability in mind, ensuring the wrapping machine will not tilt or move during the film wrapping process. Furthermore, the operation of the rotating seat 33, driven by a motor, rotates the support seat 34, allowing the supported items to be evenly wrapped with film during the wrapping process. This rotating mechanism not only improves the efficiency of film wrapping but also ensures the uniformity and aesthetics of the wrapping, making the wrapped items more stable and attractive.

[0030] Working principle: First, the film wrapping machine, which can flatten the film, is supported at the bottom by the base plate 32. The operation of the rotating seat 33 drives the item supported by the support seat 34 to rotate. The operation of the electric lifting frame 31 drives the lifting plate 3 to move up and down inside, thereby adjusting the height of the support frame 1. The support frame 1 supports the support plate 12, and the film roller 15 is placed outside the air shaft 14. The operation of the air shaft 14 clamps and fixes the film roller 15. The lifting block 21 moves downward inside the lifting groove 2, and the operation of the connecting rotating shaft 22 drives the connecting plate 23 to flip, so that the annular rotating shaft 24 connects to the top of the air shaft 14, thereby assisting the air shaft 14. The support improves the stability of the air shaft 14. The rotation of the rotating disk 13 and the annular rotating shaft 24 drives the film roller 15 to rotate. The film is guided and flattened by two rubber rollers 11. The film is supported by the flattening roller 18. The shape of the flattening roller 18 flattens the film, improving the flattening effect of the film winding machine. The support spring 110 is connected by the mounting block 111. When the flattening roller 18 is under pressure, the support spring 110 extends, thereby driving the support block 17 to rotate through the mounting shaft 16. This facilitates the straightening of the film and avoids the problem of film breakage due to excessive tension, thus improving the flattening effect of the film winding machine.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
