Description

Technical Field

[0001] The utility model belongs to the technical field of shoemaking, and relates to a cutting knife, in particular to a cutting knife for slicing on an internal mixer. Background Art

[0002] The sole processes in the prior art are mainly divided into two types. One is injection molded by an injection molding machine, and the other is cut after pressing raw rubber into sheets by an internal mixer. Among them, after pressing into sheets by the internal mixer, it is necessary to manually buckle a cutting knife mold of the required shape on the pressure roller of the internal mixer to cut out the required shape, and then manually remove the rubber sheet along the cutting contour. The disadvantages of this method are: (1) The speed of manually placing the cutting knife mold is slow, and it is necessary to adjust the rotation speed of the pressure roller of the internal mixer to a slower speed, which affects the production efficiency; (2) When manually placing the cutting knife mold, it is placed disorderly and the continuity is poor, resulting in some vacant positions that cannot be filled with raw rubber in time, affecting the quality of the slices. Content of the Utility Model

[0003] To solve the above deficiencies in the prior art, the utility model aims to provide a cutting knife for slicing on an internal mixer to achieve the purpose of improving production efficiency and improving the quality of film cutting.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A cutting knife for slicing on an internal mixer includes a mounting frame, a roller rotatably connected to the mounting frame, and a blade fixed on the roller. The blade is erected along the circumferential surface of the roller, and the contour formed by the blade matches the shape of the cutting film.

[0006] As a limitation of the utility model, the contour formed by the blade is in the shape of a sole, and the head end and the tail end of the sole-shaped contour formed by the blade are isolated by a blank area.

[0007] As a further limitation of the utility model, two blades surrounding the sole shape are arranged at intervals along the circumferential direction of the roller, and the two sole-shaped blades are isolated by a blank area.

[0008] As another limitation of the utility model, the contour formed by the blade is in the shape of a long strip, the head end and the tail end of the blade are isolated by a blank area, and segmented blades for closing are fixed at both the head end and the tail end of the blade.

[0009] As a limitation of the utility model, a plurality of blades are arranged at intervals along the axial direction of the roller.

[0010] As a third limitation of the utility model, two pairs of clamps are fixed on the mounting frame.

[0011] Due to the adoption of the above technical solution, the beneficial effects achieved by the present utility model compared with the prior art are as follows:

[0012] (1) The present utility model uses a continuously rotating roller to cut the rubber sheet on the pressure roller of the open mill, so that the cut rubber sheet forms the shape of the blade contour, meeting the requirements of the shape needed for shoe making, eliminating the trouble of manually placing the mold. Moreover, as the roller rotates with the pressure roller, it can continuously cut the rubber sheet, greatly improving the production efficiency. At the same time, since the position of the roller is fixed, the slicing positions are generated in sequence, and the vacant positions can be filled in sequence, ensuring the consistency of the thickness and quality of the rolled raw rubber, improving the quality of the rubber sheet, and reducing defective products.

[0013] (2) The present utility model is provided with multiple cutting areas, which can simultaneously generate multiple strip-shaped rubber sheets, with high production efficiency.

[0014] (3) The head and tail ends of the blade of the present utility model are separated by blank areas, facilitating the manual removal of the cut rubber sheet.

[0015] (4) The two sole-shaped blades on the roller of the present utility model enable the roller to cut two sole-shaped rubber sheets in one rotation, improving the production efficiency.

[0016] In summary, the present utility model can replace manual placement of the mold, improve the production efficiency, and generate cutting areas in sequence, enabling timely filling of the raw rubber, improving the forming quality of the rubber sheet, and is suitable for being installed on an open mill to cut rubber sheets.

[0023] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and understanding the present utility model, and are not used to limit the present utility model.

[0024] Embodiment 1 A cutter for slicing on an open mill

[0025] As Figure 1 shown, this embodiment includes a mounting frame 1, a roller 4 rotatably connected to the mounting frame 1, and a blade 5 fixed to the roller 4. The mounting frame 1 is used to be fixed on an open mill 8, so that the blade 5 on the roller 4 is tangent to the pressure roller of the open mill 8.

[0026] The mounting frame 1 is U-shaped. On both sides of the open end, mounting blocks 2 are fixedly provided, and on the closed end, two pairs of hoop clamps 3 are fixedly provided. The hoop clamps 3 adopt the structure in the prior art and are fixedly connected using bolts. During installation, the hoop clamps 3 on the mounting frame 1 are fixed on the mounting shaft 9 of the open mill 8, and the hoop clamps 3 and the mounting shaft 9 are fastened with bolts. This structure can arbitrarily adjust the angle of the mounting frame 1 to make the roller 4 tangent to the pressure roller of the open mill 8.

[0027] As Figure 2 shown, the roller 4 is cylindrical. The two sides of the roller 4 are rotatably connected to the mounting blocks 2 of the mounting frame 1 through rotating shafts. The blade 5 is the cutting part of the roller 4. The blade 5 is erected along the circumferential surface of the roller 4. The blade 5 is sheet-shaped and encloses the required shape, so that the contour formed by the blade 5 matches the shape of the cut rubber sheet.

[0028] The contour formed by the blade 5 on the roller 4 is in the shape of a sole, so that the cut rubber sheet forms the shape of a sole for making soles. There are two blades 5 enclosing the sole shape arranged at intervals along the circumferential direction of the roller 4. That is, when the roller 4 rotates one circle, two sole-shaped rubber sheets can be cut off. In order to prevent the two sole-shaped cut marks from crossing, a blank area 7 is provided between the head and the tail of the blade 5 forming the sole contour.

[0029] As Figure 3 shown, when using this embodiment, the original equipment of the open mill 8 is provided with a mounting shaft 9. The mounting shaft 9 is arranged parallel to the pressure roller of the open mill 8 and has a certain distance from the pressure roller. The two hoop clamps 3 of the mounting frame 1 are fixed on the mounting shaft 9 with bolts, so that the blade 5 on the roller 4 is tangent to the pressure roller. During installation, if the tangency is not enough, the angle between the mounting frame 1 and the mounting shaft 9 can be changed by adjusting the hoop clamps 3 to ensure that the blade 5 of the roller 4 is tangent to the pressure roller. During cutting, start the open mill 8 to make the raw rubber adhere to the pressure roller to form a rubber sheet. The rotation of the pressure roller drives the rotation of the roller 4, so that the blade 5 makes a cut mark on the rubber sheet, and the required-shaped rubber sheet can be taken off manually along the cut mark.

[0030] Embodiment 2 A cutter for slicing on an open mill

[0031] like Figure 4 As shown, the structure of this embodiment is basically the same as that of embodiment 1, except for the shape of the blade 5 on the roller 4. In this embodiment, the profile formed by the blade 5 is in the shape of a long strip, and multiple blades 5 are arranged at intervals along the axial direction of the roller 4, so that the roller 4 rotates one circle and can cut multiple strips of film in parallel. In order to produce cut marks at the beginning and end of the strip film, the beginning and end of the blade 5 are separated by a blank area 7, and the beginning and end of the blade 5 are fixed with a segmented blade 6 for closure, that is, the segmented blade 6 is arranged vertically with the blade 5, so that the area surrounded by the blade 5 forms a closed long strip, and a long strip of film is cut out to make the surrounding strip of the sole.

[0032] It should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
