Description

Technical Field

[0001] The utility model relates to the technical field of film cutting knives, and more specifically, to a roll film cutting knife. Background Art

[0002] Rolled films are commonly used in the packaging field, which are packaging films rolled up. The main advantage is to save the cost of the entire packaging process. Common ones include PVC shrink film rolls, opp rolls, pe rolls, pet protective films, composite rolls, etc.

[0003] At present, after the rolled film is used in packaging, it needs to be cut off by a cutting knife. However, most of the existing rolled film cutting knives are in a single cutting knife mode. Due to the stretchability of the rolled film, it is easy for the direction of the rolled film and the cutting knife not to be perpendicular, resulting in reduced cutting efficiency or uneven cutting. Moreover, during long-term use, the cutting knife is prone to wear and has a low service life. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the present utility model is to provide a roll film cutting knife, aiming to solve the problems that most of the existing roll film cutting knives are in a single cutting knife mode. Due to the stretchability of the rolled film, it is easy for the direction of the rolled film and the cutting knife not to be perpendicular, resulting in reduced cutting efficiency or uneven cutting. Moreover, during long-term use, the cutting knife is prone to wear and has a low service life.

[0006] 2. Technical Solutions

[0007] To solve the above problems, the present utility model adopts the following technical solutions:

[0008] A roll film cutting knife includes a tool holder. One end of the tool holder is provided with an assembly opening, and two tool bodies are detachably connected in the assembly opening. Two waist-shaped holes are provided on the tool holder, and both waist-shaped holes penetrate the assembly opening. A set of connection holes are provided on each of the two tool bodies, and the two sets of connection holes correspond to the two waist-shaped holes.

[0009] As a preferred solution of the present utility model, each tool body includes a connection part and a cutting part. The connection part is detachably connected in the assembly opening, and a set of connection holes are provided on the connection part. The cutting part is fixedly connected to the connection part, and the connection part is located on one side of the tool holder.

[0010] As a preferred solution of the present utility model, the two connection parts are arranged in a staggered manner, and a cutting angle is provided between the two cutting parts.

[0011] As a preferred solution of the present utility model, each set of connection holes is provided with two, and each set of two connection holes corresponds to the two waist-shaped holes respectively.

[0012] 3. Beneficial effects

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] (1) In this solution, two tool bodies are installed on the tool rest through two waist-shaped holes and two groups of connection holes. After the two tool bodies are installed, a cutting edge is formed. When the winding film passes through the cutting edge of the cutting tool, the included angle between the two cutting parts passes in a relative direction, ensuring the cutting direction, enabling each cutting to be in an optimal working condition, thereby reducing the uneven cutting condition and improving the cutting efficiency.

[0015] (2) In this solution, the two tool bodies are assembled into a double-cutting tool mode, and the two tool bodies cut the winding film simultaneously, effectively reducing the cutting resistance and extending the service life. The two waist-shaped holes and two groups of connection holes are correspondingly installed with two tool bodies, and the cutting position can be adjusted to enable the two tool bodies to achieve the effect of repeated use, further extending the service life.

[0024] Embodiment:

[0025] Please refer to Figures 1-3 , a roll film cutter, including a tool holder 1. One end of the tool holder 1 is provided with an assembly opening 2. Two tool bodies 3 are detachably connected in the assembly opening 2. Two waist-shaped holes 4 are provided on the tool holder 1, and both of the two waist-shaped holes 4 penetrate through the assembly opening 2. A set of connection holes 5 are provided on each of the two tool bodies 3, and the two sets of connection holes 5 correspond to the two waist-shaped holes 4.

[0026] In this embodiment, the two tool bodies 3 are inserted into the assembly opening 2. By screwing through the two waist-shaped holes 4 and the two sets of connection holes 5, the two tool bodies 3 are fixed on the tool holder 1 to complete the assembly of the double cutters. The two tool bodies 3 after assembly correspond to each other and cut the roll film smoothly. When the two tool bodies 3 are worn, by adjusting the correspondence between the two sets of connection holes 5 and the two waist-shaped holes 4, the positions of the two tool bodies 3 can be changed, so that the two tool bodies 3 can continue to be used.

[0027] Specifically, each tool body 3 includes a connecting portion 32 and a cutting portion 31. The connecting portion 32 is detachably connected in the assembly opening 2, and a set of connection holes 5 are provided on the connecting portion 32. The cutting portion 31 is fixedly connected to the connecting portion 32, and the connecting portion 32 is located on one side of the tool holder 1.

[0028] In this embodiment, the connecting portion 32 is used to connect the tool holder 1, and the cutting portion 31 is used to cut the roll film. By adjusting the corresponding position of a set of connection holes 5 and the two waist-shaped holes 4, the installation position of the cutting portion 31 can be changed, so that the tool body 3 can continue to be used after being worn.

[0029] Specifically, the two connecting parts 32 are distributed in a staggered manner, and a cutting angle is provided between the two cutting parts 31.

[0030] In this embodiment, after the two connecting parts 32 are staggeredly installed in the assembly port 2, the two cutting parts 31 form a cutting angle, and the angle is the incision position.

[0031] Specifically, each group of connecting holes 5 is set to two, and the two connecting holes 5 in each group respectively correspond to the two waist-shaped holes 4.

[0032] In this embodiment, by making the two connecting holes 5 in each group correspond to the two waist-shaped holes 4, the installation positions of the two tool bodies 3 can be adjusted, so as to adjust the incision position, and the two tool bodies 3 can continue to be used after being worn.

[0033] Working principle: The two connecting parts 32 are inserted into the assembly port 2, and the two connecting parts 32 are fixed on the tool holder 1 by screws passing through the two waist-shaped holes 4 and the two groups of connecting holes 5, completing the assembly of the double cutting knives. A cutting edge is formed between the two cutting parts 31 to cut the rolled film smoothly. When the two tool bodies 3 are worn, by adjusting the correspondence between the two groups of connecting holes 5 and the two groups of waist-shaped holes 4, the cutting edge between the two cutting parts 31 is adjusted, and the two tool bodies 3 can continue to be used.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
