Description

Technical Field

[0001] The utility model belongs to the technical field of shoemaking and relates to an open mill, in particular to an open mill with a slicing mechanism. Background Art

[0002] An open mixing mill, also known as an open rubber mixer, is a device for plasticating, mixing, sheeting, and crushing raw rubber. Its main structure consists of two cooperating rollers that rotate simultaneously, using the rollers to compress the raw rubber for mixing, crushing, or sheeting. In the shoemaking industry, sheeting is primarily used to create specific features on the sole. In the prior art, after sheeting on the mixing mill, the rubber adheres to the rollers. A mold of the desired shape is then manually placed on the rollers, creating a deep indentation. The resulting sheet is then removed by hand. This method has the following disadvantages: the molds are placed in a disorderly manner, resulting in poor continuity, which can prevent some vacant spaces from being filled with raw rubber in a timely manner. Furthermore, manual labor efficiency is low, and tearing the sheet by hand is dangerous, resulting in poor safety. Utility Model Content

[0003] In order to solve the above deficiencies in the prior art, the present invention aims to provide an open mill with a slicing mechanism, so as to achieve the purpose of improving slicing continuity, improving work efficiency and improving safety.

[0004] In order to achieve the above purpose, the technical solutions adopted by the present utility model are as follows:

[0005] A mixing mill with a slicing mechanism comprises a bracket, a pressure roller mechanism rotatably arranged on the bracket, and a first mounting shaft fixed to the bracket. The slicing mechanism also comprises a mounting frame assembled on the first mounting shaft and a roller rotatably connected to the mounting frame. The surface of the roller is provided with a blade matching the cutting shape, and the blade is arranged tangent to the pressure roller of the pressure roller mechanism.

[0006] As a limitation of the present invention, the mounting frame is hingedly arranged on the first mounting axis and also includes an angle adjustment device for adjusting the rotation angle of the mounting frame around the first mounting axis. A second mounting axis is fixed on the bracket, and the angle adjustment device is assembled on the second mounting axis.

[0007] As a further limitation of the present invention, the angle adjustment device includes a mounting seat, a screw and a handwheel, the mounting seat is rotatably set on the second mounting shaft, the screw is threadedly connected to the mounting seat, the handwheel is threadedly connected to the screw, and a U-shaped fork is fixed to the end of the mounting frame where the hob is not set, the U-shaped fork is sleeved on the screw, and the top surface of the U-shaped fork is against the bottom surface of the handwheel.

[0008] As another limitation of the present invention, the mounting bracket is provided with an arc-shaped groove, which is buckled on the first mounting shaft to form a hinge point.

[0009] As a limitation of the present invention, a handle is fixedly provided on the mounting frame.

[0010] As a third limitation of the present invention, the outline formed by the blade is a long strip, and the head end and the tail end of the blade are separated by a blank area.

[0011] As a fourth limitation of the present invention, the outline formed by the blade is in the shape of a shoe sole, and the head end and the tail end of the shoe sole-shaped outline formed by the blade are separated by a blank area.

[0012] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0013] (1) The utility model sets a roller cutter attached to the roller pressing mechanism to cut the film. As the roller pressing mechanism rotates, the roller cutter is driven to rotate, so that the blade on the roller cutter contacts the film attached to the roller pressing mechanism, and the film of the corresponding shape is cut, which saves the trouble of manual operation. As the roller cutter rotates, it can continuously form gaps at regular positions, so that the raw rubber is filled in time, and the slicing efficiency is improved. Only the cut film needs to be taken away manually, which greatly improves safety.

[0014] (2) The utility model can change the tangent position of the roller and the pressure roller mechanism through the angle adjustment device to adapt to films of different thicknesses and rollers of different diameters, and has strong versatility;

[0015] (3) The utility model can buckle the mounting bracket onto the first mounting shaft, and utilize the principle of lever to make the hand wheel press one side of the U-shaped fork, which makes disassembly and assembly more convenient and also facilitates the rapid replacement of different hobs;

[0016] (4) The blades of different shapes on the hob of the utility model can cut films of different shapes, which makes the hob more versatile and more practical.

[0017] In summary, the utility model can continuously and quickly cut films of different shapes, has high working efficiency and high safety, and is suitable for being installed on an open mixing mill to cut films. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention and are not intended to limit the present invention.

[0026] Example 1: A mixing mill with a slicing mechanism

[0027] like Figure 1 As shown, this embodiment includes a bracket 1 and a roller mechanism rotatably mounted on the bracket 1. A first mounting shaft 3 and a second mounting shaft 4 are fixedly mounted on the bracket 1 parallel to the length of the roller mechanism. The roller mechanism includes two tangential rollers 2. The rotation of the two rollers 2 causes the raw rubber to adhere to the rollers 2. This structure is similar to an open mixing mill in the prior art and will not be described in detail. This embodiment adds a slicing mechanism to the open mixing mill to automatically and continuously cut the film into the desired shape.

[0028] like Figure 2 As shown, the slicing mechanism includes a mounting frame 5 and a rotary cutter 6. The mounting frame 5 is U-shaped, with two mounting blocks 51 fixed to one side of the mounting frame 5, one fixed to either side of the open end. The other side of the mounting frame 5 is provided with two arc-shaped grooves 52, one located midway along the length of the mounting frame 5 and on either side. A U-shaped fork 55 is fixed to the end of the mounting frame 5 not provided with the rotary cutter 6, secured to the closed end of the mounting frame 5 via a positioning rod 54. A handle is provided on the mounting frame 5 to facilitate lifting and replacing the entire slicing mechanism.

[0029] like Figure 2 、 Figure 3As shown, the cutter 6 is rotatably connected to the mounting frame 5 via a rotating shaft. The two ends of the rotating shaft are respectively arranged on the two mounting blocks 51 of the mounting frame 5, so that the cutter 6 is located at the opening of the mounting frame 5. The surface of the cutter 6 is provided with a blade 61 that matches the cutting shape, and the blade 61 is arranged tangentially to the pressure roller mechanism. In this embodiment, the profile formed by the blade 61 is long and strip-shaped. Multiple blades 61 are arranged at intervals along the axial direction of the cutter 6. When the cutter 6 rotates one circle, it can cut multiple strips of film in parallel, cutting out long strips of film for making the sole strip. In order to also produce cut marks at the beginning and end of the strip of film, the beginning and end of the blade 61 are separated by a blank area, and the beginning and end of the strip are surrounded by blades 61, so that the long strip profile forms a closed profile. The blank area is used to disconnect the strip of rubber, making it easy to remove manually.

[0030] When installing the slicing mechanism, the arc-shaped groove 52 on the mounting frame 5 is buckled onto the first mounting shaft 3, forming a hinged structure between the mounting frame 5 and the first mounting shaft 3. The blade 61 of the roller cutter 6 is arranged tangentially to one of the rollers 2 of the roller mechanism. The roller cutter 6 at one end of the mounting frame 5 and the U-shaped fork 55 at the other end of the mounting frame 5 form a lever structure with the first mounting shaft 3 as the fulcrum. One end of the U-shaped fork 55 is positioned by an angle adjustment device to adjust the rotation angle of the mounting frame 5 about the first mounting shaft 3 and control the position at which the roller cutter 6 and the roller 2 are tangential.

[0031] like Figure 4 As shown, the angle adjustment device includes a mounting base 7, a screw rod 8, and a handwheel 9. The mounting base 7 is U-shaped, with one open end rotatably mounted on the second mounting shaft 4. The screw rod 8 is threadedly connected to the closed end of the mounting base 7. The handwheel 9 is threadedly connected to the screw rod 8. The gap portion of the U-shaped fork 55 on the mounting base 7 is sleeved on the screw rod 8, so that the top surface of the U-shaped fork 55 abuts the bottom surface of the handwheel 9. Since the mounting frame 5 uses the hinge of the first mounting shaft 3 as a fulcrum, and one end of the mounting frame 5 is rotatably connected to the heavier hob 6, the hob 6 tends to move downward, causing the U-shaped fork 55 at the other end of the mounting frame 5 to tend to move upward. Therefore, by adjusting the position of the handwheel 9, the handwheel 9 blocks the upward movement of the U-shaped fork 55, and the U-shaped fork 55 moves in a curve around the hinge point. The mounting base 7 rotatably mounted on the second mounting shaft 4 can be adaptively adjusted to adjust its position, thereby achieving the purpose of positioning the hob 6. This structure can not only realize the positioning of the roller cutter 6, but also facilitate the adjustment of the position of the roller cutter 6 and the pressure roller 2 at any time to adapt to the thickness of different films, and can realize the rapid replacement of different roller cutters 6.

[0032] When using this embodiment, the cutter 6 is first fixed to the mounting frame 5, and then the arc-shaped groove 52 on the mounting frame 5 is buckled onto the first mounting shaft 3. The mounting base 7 of the angle adjustment device is installed on the second mounting shaft 4. The mounting base 7 is then rotated in a direction away from the U-shaped fork 55. When the screw 8 is aligned with the gap between the U-shaped fork 55, the mounting base 7 is rotated toward the U-shaped fork 55 until the screw 8 is located within the gap between the U-shaped fork 55. The hand wheel 9 is rotated so that the hand wheel 9 contacts the top surface of the U-shaped fork 55. By adjusting the position of the hand wheel 9 on the screw 8, the position of the cutter 6 and the pressure roller 2 is adjusted. After installation is completed, the mill is started, and the raw rubber passes through the pressure roller 2 of the pressure roller mechanism into a sheet and adheres to the pressure roller 2. The rubber on the pressure roller 2 drives the cutter 6 to rotate, and the blade 61 on the cutter 6 cuts the rubber into strips. The cut rubber is then manually removed.

[0033] Example 2: A mixing mill with a slicing mechanism

[0034] like Figure 5 As shown, this embodiment is essentially identical in structure to Example 1, differing in the shape of blade 61 on hob 6. In this embodiment, blade 61 forms a shoe sole-shaped profile, giving the cut film a sole-shaped shape for use in making shoe soles. Two blades 61 are spaced apart along the circumference of roller 4, forming two sole-shaped film sheets per rotation of hob 6. To prevent the two sole-shaped cuts from intersecting, a blank space is provided between the leading and trailing ends of blade 61, where the sole outline is formed.

[0035] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
