Description

Technical Field

[0001] The present invention relates to the field of rubber refining equipment, in particular to a rubber refining machine and a working method thereof. Background Art

[0002] A rubber mixing mill, especially an open-type mixing mill, generally consists of a roller assembly and a cutting assembly. The roller assembly is used to perform mixing operations such as shearing and extruding the rubber compound using the roller circumference and the gaps between the rollers. The cutting assembly is used to cut the mixed rubber compound.

[0003] However, currently, when mixing rubber with a roller assembly, an operator must stand beside the roller assembly to knead the rubber or add auxiliary materials to achieve the desired mixing. However, during this process, the cutting assembly is fixed between the roller assembly and the operator. The cutting blade of the cutting assembly does not operate during mixing, and the cutting assembly can easily interfere with the operator's manual mixing operations. Furthermore, during mixing, the rubber can easily get stuck between the cutting assembly and the roller assembly, forcing the operator to manually clean the rubber before mixing can resume. Repeated rubber jams reduce the mixing efficiency of the rubber compound, wasting manpower and time. Summary of the Invention

[0030] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections, or communication; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0031] Figure 1 1 is a schematic diagram of the working state of the rubber mixing machine 100 when mixing rubber materials according to an embodiment of the present invention. Figure 2 1 is a schematic diagram of the working state of the rubber mixing machine 100 when cutting rubber material according to an embodiment of the present invention.

[0032] See Figure 1 and Figure 2 The rubber mixing machine 100 of the embodiment of the present invention includes a rubber mixing machine body 10, a roller assembly 20 and a cutting assembly 30.

[0033] The roller assembly 20 is rotatably mounted on the rubber mixer body 10 about a horizontal axis and is used to mix the rubber material. For example, the roller assembly 20 includes a first roller 21 and a second roller 22. The first roller 21 and the second roller 22 are horizontally arranged and rotatable about the horizontal axis. The roller assembly 20 utilizes the circumferences of the first roller 21 and the second roller 22 and the gap between the circumferences of the first roller 21 and the second roller 22 to shear and squeeze the rubber material, and cooperates with manual kneading of the rubber material or the addition of auxiliary materials to achieve mixing of the rubber material.

[0034] The cutting assembly 30 is arranged on one side of the roller assembly 20 and can be rotatably arranged on the rubber mixing machine body 10 in a horizontal plane to switch between the cutting position and the rubber mixing position. Figure 1 As shown, in the mixing position, the cutting assembly 30 and the roller assembly 20 are arranged vertically in a horizontal plane, so as to form a mixing operation area 301 suitable for an operator to stand and perform manual mixing operations between the cutting assembly 30 and the roller assembly 20. Figure 2 As shown, at the cutting position, the cutting assembly 30 and the roller assembly 20 are arranged side by side in a horizontal plane to cut the mixed rubber material.

[0035] Thus, the working method of the rubber mixing machine 100 of the present invention comprises the following steps:

[0036] S10: Rotate the cutting assembly 30 in a direction away from the roller assembly 20 in a horizontal plane so that the cutting assembly 30 and the roller assembly 20 are vertically arranged in the horizontal plane to form a mixing operation area 301 between the cutting assembly 30 and the roller assembly 20.

[0037] S20: After the roller assembly 20 completes mixing the rubber material, the cutting assembly 30 is rotated in a horizontal plane toward the roller assembly 20 so that the cutting assembly 30 and the roller assembly 20 are arranged side by side in the horizontal plane, so that the cutting assembly 30 can cut the mixed rubber material.

[0038] In other words, before the roller assembly 20 mixes the rubber material, the operator can rotate the cutting assembly 30 in a horizontal plane in a direction away from the roller assembly 20, thereby rotating the cutting assembly 30 into a shape as shown in FIG. Figure 1The state shown makes the cutting assembly 30 and the roller assembly 20 vertically arranged in a horizontal plane, and a mixing operation area 301 is formed between the cutting assembly 30 and the roller assembly 20, so that the operator can stand in the mixing operation area 301 and cooperate with the rotation of the roller assembly 20 to perform manual mixing operations such as kneading the rubber material or adding auxiliary materials, thereby enabling the roller assembly 20 to achieve mixing of the rubber material. The operator has a large manual operation space, and the manual mixing operation is not easily interfered with. Moreover, when mixing the rubber material, the rubber material will not be stuck between the cutting assembly 30 and the roller assembly 20, and the rubber mixing efficiency is high. After the rubber material on the roller assembly 20 is mixed, the operator leaves the mixing operation area 301, and the cutting assembly 30 rotates in the horizontal plane toward the roller assembly 20, thereby rotating the cutting assembly 30 and the roller assembly 20 into the following state. Figure 2 In the state shown, the cutting assembly 30 and the roller assembly 20 are arranged side by side in a horizontal plane, so that the mixed rubber material is cut by the cutting assembly 30 .

[0039] Therefore, when the rubber mixing machine 100 of the present invention mixes rubber materials, manual mixing operations are not easily interfered with, and the rubber materials are not easily stuck, thereby achieving high mixing efficiency.

[0040] Figure 3 is a schematic structural diagram of the cutting assembly 30 according to an embodiment of the present invention, see Figure 2 and Figure 3 The rubber mixing machine body 10 is provided with a mounting base 11, and the mounting base 11 is provided with a rotatable vertical shaft 12. The cutting assembly 30 includes a support bracket 31 and a cutting component 32. One end of the support bracket 31 is connected to the vertical shaft 12, and the other end is a free end. Figure 4 It is a schematic structural diagram when the cutting component 32 is connected to the supporting bracket 31. Figure 5 Figure 3 is a cross-sectional view of the cutting component 32 cutting the rubber material. The cutting component 32 includes a cutter 321, a first adapter 322, and a cutting drive 323. The cutter 321 is positioned below the roller assembly 20. One end of the first adapter 322 is connected to the support bracket 31 for vertical rotation. The other end is provided with the cutter 321, which is used to drive the cutter 321 to rotate upward toward the rubber material on the roller assembly 20 to cut the rubber material. The cutting drive 323 is connected to the first adapter 322 for driving the first adapter 322 to rotate vertically.

[0041] In this way, when the vertical rotating shaft 12 rotates, thereby driving the supporting bracket 31 to rotate in the horizontal plane, and then the supporting bracket 31 is horizontally close to the roller assembly 20 and arranged side by side with the roller assembly 20 in the horizontal plane, the cutting drive member 323 drives the first adapter 322 to rotate upward, thereby driving the cutter 321 to rotate upward and approach the rubber material on the roller assembly 20 arranged above it, thereby completing the cutting of the rubber material.

[0042] Specifically, the cutting drive member 323 can be a first drive cylinder, which is tilted and connected to the first adapter 322, thereby driving the first adapter 322 to rotate up and down around the rotation connection point between the first adapter 322 and the support bracket 31.

[0043] According to some preferred embodiments of the present invention, see Figure 3 and Figure 4 The cutting members 32 are multiple and are spaced apart along the support bracket 31 at adjustable intervals, so that the cutting distance between the multiple cutters 321 is adjustable. Thus, when cutting rubber, the present invention can adjust the cutting distance between the multiple cutters 321 by adjusting the distance between the multiple cutting members 32, thereby enabling the entire rubber to be cut into different sizes according to different cutting requirements, thus having a wide range of applications.

[0044] Specifically, in Figure 3 In the example, there are five cutting parts 32, and the five cutting parts 32 are arranged at intervals. Of course, it can be understood that the number of the cutting parts 32 is not limited to this and can be set accordingly according to needs.

[0045] According to some preferred embodiments of the present invention, see Figure 3 and Figure 4 The cutting assembly 30 further includes a plurality of sliders 33 and a plurality of threaded handles 34. The plurality of sliders 33 are slidably disposed on the support bracket 31 and are connected one by one to the plurality of cutting components 32. The plurality of threaded handles 34 pass through the plurality of sliders 33 and abut against the support bracket 31 to lock the plurality of sliders 33. In this way, when the spacing distance between the plurality of cutting components 32 needs to be adjusted, the threaded handles 34 can be unscrewed from the sliders 33, and then the sliders 33 can be slid, thereby adjusting the distance between the plurality of cutting components 32 by adjusting the spacing distance between the plurality of sliders 33.

[0046] According to some preferred embodiments of the present invention, see Figure 3 and Figure 5The cutting assembly 30 further includes a protective cover 35, a second adapter 36, and a protective drive 37. When the cutter 321 is not cutting rubber, the protective cover 35 is positioned outside the cutter 321. One end of the second adapter 36 is rotatably connected to the support bracket 31, and the other end is connected to the protective cover 35. The first adapter 322 and the second adapter 36 rotate in opposite directions. The protective drive 37 is connected to the second adapter 36 and is used to drive the second adapter 36 to rotate.

[0047] In this way, when the cutter 321 is not cutting rubber, the cutter 321 is disposed within the protective cover 35. The protective cover 35 protects the cutter 321 and extends its service life. Furthermore, when the cutter 321 is required to cut rubber, the cutter 321 can rotate and escape from the protective cover 35 to cut the rubber. The protective cover 35 also protects the operator when the cutter 321 is not in use, reducing the chance of the operator accidentally touching the cutter 321 and thus helping to reduce accidents.

[0048] In addition, when the cutter 321 needs to run out of the protective cover 35, the protective drive member 37 can drive the second adapter 36 to rotate in the opposite direction of the first adapter 322. For example, when the first adapter 322 rotates upward, the second adapter 36 rotates downward, so that the cutter 321 can run out of the protective cover 35 more quickly, thereby cutting the rubber material.

[0049] Specifically, the protective driving member 37 can be a second driving cylinder, which is arranged at an angle and connected to the second adapter 36, and is used to drive the second adapter 36 to rotate up and down around the rotation connection point between the second adapter 36 and the support bracket 31.

[0050] According to some preferred embodiments of the present invention, see Figure 3 The cutting assembly 30 further includes a steering handle 38, which is disposed on the support bracket 31 and is positioned away from the vertical rotation axis 12 relative to the cutting component 32. Thus, an operator can pull the steering handle 38 to rotate the cutting assembly 30 in a horizontal plane. Furthermore, since the steering handle 38 is positioned away from the vertical rotation axis 12 relative to the cutting component 32, pulling the steering handle 38 requires less effort, and the cutting assembly 30 can be easily pulled and rotated.

[0051] According to some preferred embodiments of the present invention, see Figure 3The cutting assembly 30 further includes a guide roller 39, which is disposed above the support bracket 31 and is used to guide the cut rubber material away from the roller assembly 20. Thus, after the cutter 321 has cut the rubber material, the cut rubber material can be guided to the guide roller 39 and pulled away from the roller assembly 20 by the guide roller 39, thereby allowing the cut rubber material to be stably and smoothly transported away from the roller assembly 20.

[0052] Figure 6 This is a front view of the cutting assembly 30 according to an embodiment of the present invention. Figure 6 The cutting assembly 30 further includes a scale 310, which is disposed on the support bracket 31 and extends along the arrangement direction of the plurality of cutting components 32. Thus, by observing the graduations on the scale 310, an operator can accurately determine the exact spacing distance between the plurality of cutting components 32, thereby facilitating precise adjustment of the spacing distance between the plurality of cutting components 32 and improving adjustment accuracy.

[0053] According to some preferred embodiments of the present invention, see Figure 6 The rubber mixer 100 further includes a locking rod 310. A first locking hole 101 is formed on the mounting base 11 of the rubber mixer body 10, and a second locking hole 3101 is formed on the support bracket 31. When the cutting assembly 30 is in the cutting position, the first locking hole 101 and the second locking hole 3101 are aligned. The locking rod 310 is inserted through the first locking hole 101 and the second locking hole 3101 to lock the cutting assembly 30. In this way, when the cutting assembly 30 is in the cutting position, the locking rod 310 can lock and limit the cutting assembly 30, thereby ensuring high stability when the cutting assembly 30 cuts the rubber material. After cutting is completed, the locking rod 310 can be withdrawn from the first locking hole 101 and the second locking hole 3101, allowing the cutting assembly 30 to smoothly rotate away from the roller assembly 20.

[0054] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended to be illustrative only and are not intended to limit the present invention. The advantages of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
