Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protective film winding equipment, in particular to a hand-held protective film winding device. Background Art
[0002] During the dust-proof packaging process of materials, it is often necessary to wrap the protective film on the materials to complete the packaging and film covering operation of the materials. At present, in the packaging and film covering operation, the operator needs to directly hold the protective film with both hands to package the materials, and the packaging speed is slow. Moreover, when the operator holds the paper tube of the protective film and goes around the material, it is impossible to make the protective film close to the material, and the winding effect is poor, which cannot meet the actual needs. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the above technical problems and propose a hand-held protective film winding device.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] Design a hand-held protective film winding device, including a handle, side plates arranged at both ends of the handle, a film roller arranged between the side plates for placing the protective film, and also including two guiding components arranged between the side plates. A clamping channel for the protective film to pass through is formed between the guiding components. A pressing component for pressing one of the guiding components against the other guiding component is arranged on the side plate. Wherein, the guiding component includes a roller shell and anti-slip parts arranged in an array along the outer surface of the roller shell. A pressing channel is formed between adjacent anti-slip parts for the anti-slip part of the other guiding component to enter so as to press the protective film in the pressing channel.
[0006] Further, the anti-slip part includes a support bar extending along the length direction of the roller shell and an anti-slip surface arranged on the support bar.
[0007] Further, the cross section of the support bar is arc-shaped, and the anti-slip surface is located at the top of the arc.
[0008] Further, a plurality of reinforcing ribs are arranged on the inner wall of the roller shell.
[0009] Further, the pressing component includes a lifting plate connected to the end of the roller shell through a connecting column, a sliding groove opened on the side plate for the connecting column to slide up and down, and a pushing part for pushing the lifting plate to push the guiding component towards the other guiding component.
[0010] Further, the pushing part includes a positioning plate fixed on the side plate, a spring connecting the positioning plate and the lifting plate, and a guiding column fixed on the lifting plate and slidably matched with the positioning plate.
[0011] A handheld protective film winding device proposed by the present utility model has the beneficial effects that: by arranging a pressing component and two guiding components between the side plates, when the protective film passes through the clamping channel, the anti-slip parts of the two guiding components and the pressing channel cooperate to press the protective film in the clamping channel, so as to ensure that the protective film can always be tightened when being wound around the material, making the protective film closely adhere to the material and ensuring the winding effect on the material.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0017] Referring to Figures 1-4 an embodiment of the present utility model, which discloses a handheld protective film winding device, including a handle 1, side plates 2 provided at both ends of the handle 1, a film roller 3 provided between the side plates 2 for placing a protective film 4, and two guiding components 5 provided between the side plates 2. A clamping channel 6 for the protective film 4 to pass through is formed between the guiding components 5. A pressing component 7 for pressing one guiding component 5 against the other guiding component 5 is provided on the side plates 2. Among them, the guiding component 5 includes a roller housing 501 and anti-slip parts 502 arrayed on the outer surface of the roller housing 501. A pressing channel 503 is formed between adjacent anti-slip parts 502 for the anti-slip part 502 of the other guiding component 5 to enter, so as to press the protective film 4 in the pressing channel 503.
[0018] By arranging the pressing component 7 and the two guiding components 5 between the side plates 2, when the protective film 4 passes through the clamping channel 6, the anti-slip parts 502 of the two guiding components 5 and the pressing channel 503 cooperate to press the protective film 4 in the clamping channel 6, so as to ensure that the protective film 4 can always be tightened when being wound around the material, making the protective film 4 closely adhere to the material and ensuring the winding effect on the material.
[0019] In an alternative embodiment of the present utility model, the anti-slip portion 502 includes a support strip 5021 extending along the length direction of the roller housing 501 and an anti-slip surface 5022 provided on the support strip 5021.
[0020] In an alternative embodiment of the present utility model, the cross-section of the support strip 5021 is arc-shaped, and the anti-slip surface 5022 is located at the top of the arc. Preferably, the support strip 5021 in this embodiment can be implemented with silicone or rubber materials; after the protective film 4 is pushed into the pressing channel 503 of another guiding assembly 5 by the anti-slip portion 502, on the one hand, the protective film 4 is pressed tightly in the pressing channel 503, and on the other hand, the contact between the protective film 4 and the support strip 5021 and the anti-slip surface 5022 can also increase the friction force, thereby tightening the protective film 4 and preventing the protective film 4 from slipping when it is wound around the material, improving the winding effect.
[0021] In an alternative embodiment of the present utility model, a plurality of reinforcing ribs 504 are provided on the inner wall of the roller housing 501. Preferably, the number of the reinforcing ribs 504 in this embodiment is three; through the arrangement of the reinforcing ribs 504, the structural strength of the roller housing 501 can be increased, thereby providing stable support for the contact between the support strip 5021 and the protective film 4.
[0022] In an alternative embodiment of the present utility model, the pressing assembly 7 includes a lifting plate 702 connected to the end of the roller housing 501 through a connecting column 701, a chute 703 opened on the side plate 2 for the connecting column 701 to slide up and down, and a pushing portion 704 for pushing the lifting plate 702 to push the guiding assembly 5 towards another guiding assembly 5.
[0023] In an alternative embodiment of the present utility model, the pushing portion 704 includes a positioning plate 7041 fixed on the side plate 2, a spring 7042 connecting the positioning plate 7041 and the lifting plate 702, and a guiding column 7043 fixed on the lifting plate 702 and slidably engaged with the positioning plate 7041. After the lifting plate 702 is lifted and drives the guiding assembly 5 away from another guiding assembly 5, the protective film 4 passes through the clamping channel 6, and at this time the spring 7042 is compressed; under the elastic action of the spring 7042, the lifting plate 702 drives the connecting column 701 to slide in the chute 703, so that the guiding assembly 5 contacts another guiding assembly 5 and presses the protective film 4 tightly.
[0024] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
