[0028] The following description is used to disclose the present disclosure so that those skilled in the art can implement the present disclosure. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations. The basic principles of the present disclosure defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present disclosure.
[0029] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.
[0030] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0031] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0032] In the related art, when the cutter of the mixing mill cuts the film, especially when cutting the thick film, it is difficult for the film to be smoothly and fully cut.
[0033] In view of this, the present disclosure provides a cutter assembly for an open mixing mill. When the cutter assembly for the open mixing mill is used to cut a thick film, the film can be cut smoothly and the cutting effect is good.
[0034] Figure 1 It is a structural schematic diagram of the open mixing mill according to an embodiment of the present disclosure. Figure 2 4 is a cross-sectional view of the mixing mill in a cutting state according to an embodiment of the present disclosure. Figure 3 It is a cross-sectional view of the mixing mill in an uncut state according to an embodiment of the present disclosure.
[0035] See also Figures 1 to 3 The cutter assembly for the mixing mill includes a cutter shaft 10, a first driving member 20, a cutter 30 and a second driving member 40.
[0036] The knife shaft 10 is rotatably arranged on one side of the roller assembly 92 and extends side by side with the roller assembly 92 .
[0037] It is worth mentioning that the roller assembly 92 of the open mill is used to mix the rubber material to form a film and to provide film winding. That is to say, when the open mill is running, the roller assembly 92 will mix the rubber material to form a film, and the formed film will be wound around the roller surface of the roller assembly 92.
[0038] Optionally, the roller assembly 92 includes a first roller 921 and a second roller. The first roller 921 is rotatably disposed on the open mill body 91. The second roller is rotatably disposed on the open mill body 91, and the second roller is arranged side by side with the first roller 921 and spaced apart to cooperate with the first roller 921 to mix the rubber material. Thus, when mixing the rubber material, the rubber material will be placed between the first roller 921 and the second roller, and when the first roller 921 and the second roller rotate, the roller surfaces of the first roller 921 and the second roller cooperate with each other, thereby shearing and squeezing the rubber material between the first roller 921 and the second roller. The rubber sheet formed by the rubber material extrusion will be wound around the roller surface of the first roller 921 or the second roller, and will rotate between the first roller 921 and the second roller as the first roller 921 or the second roller rotates, so as to be repeatedly squeezed and sheared, thereby achieving the mixing of the rubber material and improving the mechanical properties of the rubber material. The knife shaft 10 is rotatably arranged on one side of the first roller 921 or the second roller through which the rubber material is wound, and extends side by side with the first roller 921 or the second roller.
[0039] The first driving member 20 is connected to the knife shaft 10 to drive the knife shaft 10 to rotate. The cutter 30 is rotatably connected to the knife shaft 10 and can rotate with the knife shaft 10 relative to the roller surface of the roller assembly 92 in a far / close manner.
[0040] Optionally, the first driving member 20 includes a first telescopic member 21 and a transfer arm 22. The transfer arm 22 is connected to the first telescopic member 21 and the knife shaft 10 respectively, and extends along the radial direction of the knife shaft 10 to drive the knife shaft 10 to rotate under the drive of the first telescopic member 21.
[0041] Specifically, the first telescopic member 21 is a first cylinder. Therefore, when a predetermined amount of gas is filled into or discharged from the first cylinder, the telescopic rod of the first cylinder can be telescoped in the cylinder body, thereby driving the transfer arm 22 to drive the knife shaft 10 to rotate, and then the knife shaft 10 drives the cutter 30 to approach or move away from the roller surface of the roller assembly 92.
[0042] Thus, when the first driving member 20 drives the cutter shaft 10 to rotate around its axis, the rotation of the cutter shaft 10 drives the cutter 30 to rotate, so that the cutter 30 is close to or away from the roller surface of the roller assembly 92. The cutter 30 is rotatably connected to the cutter shaft 10 so that the cutter 30 can rotate relative to the cutter shaft 10.
[0043] In some examples, the cutter 30 may be directly rotatably connected to the cutter shaft 10 , so that the cutter 30 can rotate relative to the cutter shaft 10 .
[0044] In other examples, a knife seat 50 may be provided on the knife shaft 10 , and the cutter 30 is indirectly rotationally connected to the knife shaft 10 by being rotationally connected to the knife seat 50 , so that the cutter 30 can rotate relative to the knife shaft 10 .
[0045] The second driving member 40 is connected to the cutter 30 and is used to drive the cutter 30 to continue rotating from the position reached by the cutter shaft 10 , wherein the continued rotation includes a cutting position that touches the roller surface.
[0046] In other words, the first driving member 20 will first drive the blade shaft 10 to rotate, so that the blade shaft 10 drives the cutter 30 to rotate to a close position close to the roller surface of the roller assembly 92. Therefore, when the film to be cut is wound around the roller surface of the roller assembly 92, the second driving member 40 drives the cutter 30 to rotate relative to the blade shaft 10, so that the cutter 30 continues to rotate, and the cutter 30 rotates from the previous close position to the cutting position in contact with the roller surface of the roller assembly 92, so that the cutter 30 can fully cut the film under the drive of the second driving member 40. Therefore, the cutter assembly of the embodiment of the present disclosure can fully cut the film with a large thickness, and the cutting effect is good.
[0047] Optionally, the second driving member 40 includes a second telescopic member. The second telescopic member is connected to the cutter 30 to drive the cutter 30 to rotate relative to the cutter shaft 10 when telescoping.
[0048] Specifically, the second telescopic member is a second cylinder. Thus, when the second cylinder is filled with or discharged with gas, the telescopic rod of the second cylinder can be telescoped in the cylinder body, thereby driving the cutter 30 to rotate relative to the cutter shaft 10, so that the cutter 30 continues to rotate.
[0049] Optionally, the second driving member 40 further includes an air charging valve. The air charging valve is connected to the second cylinder and is used to adjust the air charging amount of the second cylinder. Therefore, when the thickness or viscosity of the film is relatively large, the relevant personnel can manually start the air charging valve and make the opening of the air charging valve relatively large, so that the second cylinder can be filled with more gas through the air charging valve within a predetermined time, ensuring that the cutter 30 can smoothly pass through the film with relatively large thickness or viscosity and reach the roller surface of the roller assembly 92, thereby ensuring that the film with relatively large thickness or viscosity can be smoothly cut.
[0050] When the thickness or viscosity of the film is small, the relevant personnel can manually start the inflation valve and make the opening of the inflation valve small, and the second cylinder can be filled with less gas through the inflation valve, ensuring that the cutter 30 can pass through the film with small thickness or viscosity and smoothly reach the roller surface of the roller assembly 92, thereby ensuring that the film with small thickness or viscosity can also be cut smoothly. Therefore, the present disclosure can adjust the inflation amount of the second cylinder by adjusting the opening of the inflation valve, thereby ensuring that both the thicker film and the thinner film can be cut smoothly, and the adjustment is convenient.
[0051] When the cutter assembly for the mixing mill further includes a cutter holder 50 to which the cutter 30 is rotatably connected. Optionally, the cutter holder 50 forms a fitting hole 501 for the cutter shaft 10 to fit, and the cross-sections of the cutter shaft 10 and the fitting hole 501 are cross-sections that limit relative rotation. Optionally, the cross-sections of the cutter shaft 10 and the fitting hole 501 are both non-circular cross-sections. Specifically, the non-circular cross-section is a rectangular cross-section or a diamond cross-section, etc. Thus, when the cutter 30 rotates relative to the cutter holder 50 around the rotation connection point with the cutter holder 50, the cutter holder 50 can remain stationary and fixed on the cutter shaft 10, and the cutter holder 50 is difficult to rotate during this process, thereby avoiding the situation where the cutter 30 cannot smoothly touch the roller surface of the roller assembly 92 due to the rotation of the cutter holder 50.
[0052] Optionally, the knife seat 50 is adjustable in position along the axial direction of the knife shaft 10, so that the position of the cutter 30 along the axial direction of the knife shaft 10 is adjustable. Therefore, when the position of the knife seat 50 along the axial direction of the knife shaft 10 is adjusted, the position of the cutter 30 along the axial direction of the knife shaft 10 is also adjusted. Since the knife shaft 10 and the roller assembly 92 extend side by side, the axial direction of the knife shaft 10 is parallel to the width direction of the film on the roller surface of the roller assembly 92. Therefore, when the position of the cutter 30 along the axial direction of the knife shaft 10 is adjusted, the position of the cutter 30 corresponding to the width of the film is also adjustable. Therefore, the width of the cut film formed by the cutter 30 is adjustable, and the cutter 30 can cut cut films of different widths.
[0053] Optionally, the knife seat 50 can be slidably disposed on the knife shaft 10 and form a fastening hole 502. The cutter assembly further includes a fastener 60. The fastener 60 passes through the fastening hole 502 and is fastened to the knife shaft 10, so that the knife seat 50 is fastened to the knife shaft 10.
[0054] Therefore, when adjusting the position of the knife seat 50 along the axial direction of the knife shaft 10, the knife seat 50 can slide along the axial direction of the knife shaft 10, thereby changing the position of the knife seat 50 along the axial direction of the knife shaft 10. After the position of the knife seat 50 along the axial direction of the knife shaft 10 is changed, the fastener 60 passes through the fastening hole 502 on the knife seat 50 and is fastened to the knife shaft 10, thereby achieving the fixing of the knife seat 50 to the knife shaft 10.
[0055] Figure 4 yes Figure 1 A magnified schematic diagram of part A in Figure 2. Figure 4 The knife shaft 10 is formed with a positioning hole 101 extending in the axial direction, and the fastener 60 passes through the fastening hole 502 and is fastened in the positioning hole 101. Therefore, after the knife seat 50 is fixed on the knife shaft 10, the firmness is high.
[0056] Optionally, the cutter assembly for the mixing mill further includes a cutter arm 70. The cutter arm 70 is rotatably connected to the cutter shaft 10 and is connected to the cutter 30. The second driving member 40 is connected to the cutter arm 70 to drive the cutter arm 70 to drive the cutter 30 to rotate relative to the cutter shaft 10. Thus, when the second driving member 40 is driven, the second driving member 40 drives the cutter arm 70 to rotate first, and the cutter arm 70 rotates to drive the cutter 30 to rotate.
[0057] The disclosed embodiment also provides an open mill, which includes an open mill body 91, a roller assembly 92 and the above-mentioned cutter assembly. The roller assembly 92 is rotatably arranged on the open mill body 91, and is used to mix the rubber material and provide the rubber material for winding. The cutter assembly is arranged on one side of the roller assembly 92, and is used to cut the rubber material after the open mill.
[0058] When the film formed by mixing in the open mixer according to the embodiment of the present disclosure is cut by the cutter assembly, the film can be fully cut off and the cutting effect is good.
[0059] It should be understood by those skilled in the art that the embodiments of the present disclosure described above and shown in the accompanying drawings are only examples and do not limit the present disclosure. The advantages of the present disclosure have been fully and effectively realized. The functions and structural principles of the present disclosure have been demonstrated and explained in the embodiments, and the embodiments of the present disclosure may be deformed or modified in any way without departing from the principles.
