Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a cutting tool for the metal mesh of a printing screen. Background Art

[0002] A printing screen includes an outer aluminum alloy frame and a polyester plate and a metal mesh inside it. The polyester plate is a hollow structure, and the metal mesh adheres to the lower end face of the hollow-structured polyester plate.

[0003] During the production process of the metal mesh, there are certain requirements for the angles of the warp and weft threads. Therefore, when cutting, it is necessary to cut according to the required angles to make the angles of the warp and weft threads meet the standards. In the prior art, an angle ruler needs to be used for measurement during cutting, which affects the work efficiency. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a cutting tool for the metal mesh of a printing screen. When cutting the metal mesh to be cut, a right-angled triangular plate is used to determine the cutting angle, so that the angles of the warp and weft threads of the metal mesh quickly and accurately meet the standards. Lines are drawn and cut according to the outer contour of the square plastic plate, effectively improving the work efficiency of metal mesh cutting.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is as follows:

[0006] A cutting tool for the metal mesh of a printing screen includes a square plastic plate and a right-angled triangular plate; a handle for convenient grasping is arranged on the square plastic plate; the acute angle α of the right-angled triangular plate is set to 22.5°; when cutting the metal mesh to be cut, the right-angled triangular plate is used to determine the cutting angle, and lines are drawn and cut according to the outer contour of the square plastic plate.

[0007] A further improvement of the technical solution of the utility model lies in that: a pull rope is further arranged on one side of the handle.

[0008] A further improvement of the technical solution of the utility model lies in that: the square plastic plate is a transparent plastic plate.

[0009] A further improvement of the technical solution of the utility model lies in that: the side length L of the square plastic plate is set to 30 cm.

[0010] A further improvement of the technical solution of the utility model lies in that: the side length L of the square plastic plate is set to 22.5 cm.

[0011] A further improvement of the technical solution of the utility model lies in that: the handle is arranged at the center position of the square plastic plate.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model is as follows:

[0014] 1. By setting a square plastic plate with the same size as the required metal mesh and a right-angled triangular plate with an acute angle of 22.5° that can determine the cutting angle, when cutting the metal mesh to be cut, the cutting angle is determined with the help of the right-angled triangular plate, which can quickly and accurately meet the standard of the angles of the warp and weft of the metal mesh, and the angles are more accurate; by drawing lines and cutting according to the outer contour of the square plastic plate, the size cutting of the metal mesh is more precise, takes less time, and effectively improves the working efficiency of metal mesh cutting; at the same time, it is more convenient and labor-saving when cutting metal meshes of different sizes in a mixed manner.

[0015] 2. By setting a pull rope on one side of the handle to make the pull rope in an eccentric position, when an adsorption phenomenon occurs between the square plastic plate and the metal mesh to be cut, the eccentric pull rope is convenient to lift the square plastic plate to break the adsorption force, which can more effectively improve the working efficiency.

[0024] It should be noted that, for the description of the specification and claims of the present utility model and the above-mentioned drawings, the terms "include" and "have" and any of their variations are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily limit to those clearly listed steps or units, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0026] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0027] The following further describes the present utility model in detail with reference to the drawings and embodiments:

[0028] As Figures 1-3 shown, a cutting tool for a metal mesh of a printing screen plate includes a square plastic plate 1 and a right-angled triangular plate 3; a handle 2 for convenient grasping is provided on the square plastic plate 1; the acute angle α of the right-angled triangular plate 3 is set to 22.5°; when cutting the metal mesh 4 to be cut, the cutting angle is determined by means of the right-angled triangular plate 3, and a line is drawn according to the outer contour of the square plastic plate 1, and then cutting is performed after the line is drawn.

[0029] Further, as Figures 4-5 shown, a pull rope 5 is further provided on one side of the handle 2. The pull rope 5 is provided on one side of the handle 2 to ensure that the pull rope 5 is in an eccentric position. When an adsorption phenomenon occurs between the square plastic plate 1 and the metal mesh 4 to be cut, the eccentric pull rope 5 is used to conveniently lift the square plastic plate 1 to break the adsorption force, which can more effectively improve the work efficiency.

[0030] Furthermore, the square plastic plate 1 is a transparent plastic plate. The setting of the transparent plastic plate not only facilitates drawing the contour line but also helps to easily discover the damage on the metal mesh 4 to be cut.

[0031] Furthermore, the side length L of the square plastic plate 1 is set to 30 cm.

[0032] Furthermore, the side length L of the square plastic plate 1 is set to 22.5 cm. The above side length dimensions are set according to the specifications of the metal mesh, and square plastic plates 1 with other dimensions can also be set.

[0033] Furthermore, the handle 2 is arranged at the center position of the square plastic plate 1.

[0034] Furthermore, the handle 2 is a hollow cylinder. The design of the hollow cylinder effectively reduces the weight of the handle 2 and also facilitates grasping.

[0035] Usage method:

[0036] As Figure 6 shown, place the right-angled triangular plate 3 and the square plastic plate 1 on the metal mesh 4 to be cut. Align the right-angled side of the acute angle α of the right-angled triangular plate 3 with one side of the metal mesh 4 to be cut, place one side of the square plastic plate 1 on the hypotenuse of the right-angled triangular plate 3, and appropriately adjust the distance between the vertex angle of the acute angle α of the right-angled triangular plate 3 and the included angle between the two sides of the metal mesh 4 to be cut to ensure that the two vertex angles of the square plastic plate 1 respectively abut against the two sides of the metal mesh 4 to be cut. At this time, the metal mesh 4 to be cut is tilted upward by 22.5°. At this time, the cutting angle of the metal mesh is determined (that is, the angles of the warp and weft of the metal mesh meet the requirements). Draw the contour line according to the outer contour of the transparent square plastic plate 1 (as Figure 6 shown). After drawing the first contour line, use the handle 2 to pick up the square plastic plate 1, align one side of the square plastic plate 1 with one side of the first contour line, and draw the next one in sequence, and so on. After all the contour lines to be cut are drawn, then use scissors to cut according to the contour lines, and a metal mesh with the angles of the warp and weft meeting the requirements can be obtained.

[0037] When using the square plastic plate 1 to draw the contour line, an adsorption phenomenon may occur between the square plastic plate 1 and the metal mesh 4 to be cut. When adsorption occurs, using the eccentric pull rope 5 to lift the square plastic plate 1 can break the adsorption force.

[0038] Figure 6 The drawn one is a wiring diagram of a kind of specification metal mesh. On the metal mesh 4 to be cut, square plastic plates 1 with different specifications can also be used for mixed cutting of metal meshes with different sizes. The usage method of the right-angled triangular plate 3 is the same as above, so that the mixed cutting is more convenient and fast.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
