Therefore, it is widely used in industry. During the preparation of thermoplastic elastomer (TPE), a mixer is generally required to mix the materials.

[0003] The prior art discloses a mixer comprising a machine body and a stirring mechanism, the stirring mechanism comprising a stirring frame and a rotating motor. The stirring frame is located at the bottom of a chamber within the machine body and is rotatably connected to the machine body, with the end of the stirring frame spaced a certain distance from the inner sidewall of the machine body.

During use, the material to be mixed is placed in the machine body, and the rotating motor then drives the stirring frame to rotate, causing the stirring frame to stir and mix the material.

[0004] Regarding the above-mentioned related technologies, since there is a certain distance between the end of the stirring frame and the inner wall of the machine body, when the material is stirred, the material in contact with the inner wall of the inner chamber of the machine body will easily adhere to the inner wall of the machine body, making it difficult to contact the stirring frame, and then difficult to separate from the inner wall of the inner chamber of the machine body, which reduces the uniformity of the material stirring, so it needs to be improved. Summary of the Invention

[0009] By adopting the above technical solution, the scraper frame and the drive assembly are arranged so that the drive member can drive the scraper frame to rotate through the drive assembly, so that the scraper frame can be in two states: open and retracted. Therefore, when the scraper frame is needed, the scraper frame will be in contact with the inner wall of the machine body, effectively reducing the time for the scraper frame to be in contact with the inner wall of the machine body, thereby reducing the wear between the scraper frame and the inner wall of the machine body and ensuring the service life of the scraper frame.

When the scraper frame is against the inner wall of the machine body, it is located on the sliding path of the reinforcement frame. The reinforcement frame is used to be inserted into the scraper frame, and the linkage assembly is used to drive the reinforcement frame to slide.

[0015] By adopting the above technical solution and setting up the reinforcement mechanism, the linkage assembly can drive the reinforcement frame to slide, so that the reinforcement frame can be inserted into the scraper frame in the open state after sliding, thereby reinforcing the scraper frame, reducing the chance of damage to the scraper frame due to uneven force during the rotation of the stirring frame, effectively ensuring the service life of the scraper frame, and at the same time reducing the chance of the scraper frame offset due to damage and hitting the inner wall of the machine body.

The main frame is slidably connected to the setting frame and is connected to the corresponding linkage rack. The intermittent frame is slidably connected to the main frame and is rotatably connected to the transmission frame. The elastic member uses its own elastic force to allow the main frame to drive the intermittent frame to slide together, and the driving member is used to drive the main frame to slide.

[0019] By adopting the above technical solution, the setting of the sleeve frame makes it possible that when the driving member drives the main body frame to slide, the elastic member can use its own elastic force to make the main body frame, the intermittent frame and the elastic member form a unified whole, so that the main body frame can drive the intermittent frame to move together, and at the same time, when the driving frame moves to the specified position, the elastic member can be compressed, so that the main body frame and the intermittent frame are relatively displaced, so that when the scraper frame moves relative to the stirring frame, the reinforcement frame can be smoothly inserted into the scraper frame under the drive of the linkage assembly, effectively ensuring the smooth insertion of the reinforcement frame and ensuring the smooth progress of this application.

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] Example 1: Example 1 of the present application discloses a mixer for preventing material from sticking together. Figure 1 and Figure 2 The material-adhesion preventing mixer includes a body 1 and a stirring mechanism 2, wherein the stirring mechanism 2 includes a stirring frame 21. The stirring frame 21 is further provided with a scraping mechanism 3, which includes a scraping frame 31. The scraping frame 31 is provided on the stirring frame 21 and is used to abut against the inner side wall of the inner chamber of the body 1.

[0036] Reference Figure 1 and Figure 2 A cover body 4 is provided on the top of the body 1, and the cover body 4 and the body 1 are detachably mounted on the top of the body 1 by bolts. The stirring frame 21 is provided at the bottom of the chamber of the body 1 and is rotatably connected to the body 1 by a bearing. A plurality of stirring parts 211 are also extended from the outside of the stirring frame 21. In the embodiment of the present application, the number of stirring parts 211 is set to four, and they are distributed at equal angles along the circumference of the rotation axis of the stirring frame 21. Each stirring part 211 is integrally formed with the main body of the stirring frame 21.

[0037] Reference Figure 1 and Figure 2 The stirring mechanism 2 also includes a drive motor 22, which is fixedly mounted on the bottom end of the body 1, and the output shaft is arranged upward along the height direction of the body 1, and both extend into the body 1, and are fixedly connected to the bottom of the main body of the stirring frame 21 through a coupling to realize the driving of the stirring frame 21.

[0038] Reference Figure 1 and Figure 2A scraper frame 31 is provided at one end of each stirring part 211 away from the rotation axis of the stirring frame 21. One end of each scraper frame 31 is fixedly connected to the corresponding stirring part 211 by welding, and the other end is extended obliquely upward and abuts against the inner wall of the inner chamber of the body 1 to scrape off the material adhered to the inner wall of the body 1.

[0039] The implementation principle of the mixer for preventing material adhesion in Example 1 of the present application is as follows: when the driving motor 22 drives the stirring frame 21 to rotate, the scraper frame 31 can rotate together with the stirring frame 21, so that the scraper frame 31, which is against the inner wall of the inner chamber of the body 1, can scrape off the material adhered to the inner wall of the body 1, thereby effectively reducing the amount of material adhered to the inner wall of the inner chamber of the body 1, thereby ensuring the stirring effect of the material and improving the uniformity of the material stirring of this application.

[0040] Example 2: The difference between Example 2 of the present application and Example 1 is that: Figure 3 The cover body 4 includes a mounting cover 41 and a rotating cover 42. The mounting cover 41 is fixed to the top of the body 1 by bolts. The rotating cover 42 is rotatably connected to the cover body 4 by a pin, and the bottom wall is arranged to abut against the top of the body 1 to close the opening at the top of the body 1. In other embodiments, the top of the body 1 may also be provided with a cover lock to lock the rotating cover 42 with the body 1. This cover lock is a prior art and will not be described in detail here.

[0041] Reference Figure 3 and Figure 4 The bottom of each scraper frame 31 is rotatably connected to the end of the corresponding stirring portion 211 through a pin shaft, and when the scraper frame 31 is in the open state (that is, the state shown in the figure), it is against the inner wall of the body 1.

[0042] Reference Figure 3 and Figure 4 A setting frame 5 is also provided on the stirring frame 21. In the embodiment of the present application, the setting frame 5 is cylindrical, and the setting frame 5 is coaxially arranged with the stirring frame 21. The bottom end of the setting frame 5 is fixedly connected to the top of the stirring frame 21 by welding, and the top end of the setting frame 5 is rotatably connected to the mounting cover 42 through a bearing.

[0043] Reference Figure 3 、 Figure 4 and Figure 5The scraper mechanism 3 further includes a driving member 32 and a setting assembly 33. In the embodiment of the present application, the driving member 32 is configured as an electric telescopic rod. The electric telescopic rod is fixedly mounted on the mounting cover 41, and the piston rod extends downward along the height direction of the body 1 and extends into the body 1. The setting assembly 33 includes a sleeve frame 331 and a transmission frame 332. The sleeve frame 331 includes a main frame 3311, an intermittent frame 3312, and an elastic member 3313.

[0044] Reference Figure 4 and Figure 5 The main frame 3311 is cylindrical with openings at both ends. It is sleeved onto the mounting frame 5 and slidably connected thereto, sliding along the axis of the mounting frame 5. The mounting frame 5 defines a chamber. An extension frame 3314 is positioned at the opening of the main frame 3311. The extension frame 3314 is welded to the inner sidewall of the main frame 3311 and extends inward into the chamber of the mounting frame 5. The sidewalls of the mounting frame 5 also include slots for the extension frame 3314 to slide along with the main frame 3311. The bottom of the extension frame 3314 extends downward.

[0045] Reference Figure 4 and Figure 5 The top of the main frame 3311 is also provided with a rotating ring 6 and a mounting ring 7. The rotating ring 6 is sleeved on the top of the main frame 3311 and is rotatably connected to the main frame 3311 via a bearing. The bottom of the rotating ring 6 abuts against a protruding portion on the bottom of the main frame 3311, while the bottom of the mounting ring 7 abuts against the top of the main frame 3311 and is detachably connected via screws.

[0046] Reference Figure 4 and Figure 5 The bottom of the mounting ring 7 abuts against the top of the rotating ring 6 to limit the rotating ring 6 so that the rotating ring 6 can drive the main frame 3311 to move together. The piston rod of the electric push rod in the driving member 32 is fixedly connected to the top of the rotating ring 6.

[0047] Reference Figure 4 and Figure 5 The intermittent frame 3312 is sleeved on the bottom of the main frame 3311 and is slidably connected to the main frame 3311, and the sliding direction is the axial direction of the setting frame 5. In the embodiment of the present application, the elastic member 3313 is configured as a pressure spring. The pressure spring is sleeved on the inner wall of the main frame 3311 and is located within the intermittent frame 3312. The top end of the pressure spring abuts against the bottom of the main frame 3311, and the bottom end abuts against the inner bottom wall of the intermittent frame 3312. This allows the elastic force of the pressure spring to be transmitted to the main frame 3311 and the intermittent frame 3312, thereby allowing the main frame 3311 and the intermittent frame 3312 to move relative to each other.

[0048] Reference Figure 4 and Figure 5 A contact portion 51 is also provided on the setting frame 5. The contact portion 51 is integrally formed with the setting frame 5. The contact portion 51 is located below the intermittent frame 3312 and on the displacement path of the intermittent frame 3312, so that the intermittent frame 3312 can abut against the contact portion 51 when sliding with the main frame 3311, thereby hindering the further sliding of the intermittent frame 3312, so that the main frame 3311 can slide relative to the intermittent frame 3312.

[0049] Reference Figure 4 The scraper mechanism 3 also includes a drive assembly 34. In the embodiment of the present application, the number of the drive assemblies 34 is set to four, and they are arranged in a one-to-one correspondence with the scraper frames 31, and the transmission frames 332 are set to four groups. The four groups of transmission frames 332 are arranged in a one-to-one correspondence with the four drive assemblies 34. The four groups of transmission frames 332 are respectively located on the peripheral sides of the intermittent frame 3312, and two transmission frames 332 are arranged in each group.

[0050] Reference Figure 4 and Figure 5 Each drive assembly 34 includes a support frame 341 and a drive frame 342. In this embodiment, each drive assembly 34 includes two support frames 341, one located on opposite sides of the corresponding scraper frame 31. The two transmission frames 332 within each group are located on opposite sides of the corresponding drive frame 342. One end of each transmission frame 332 is rotatably connected to the intermittent frame 3312 via a pin, and the other end of each transmission frame 332 is rotatably connected to the corresponding drive frame 342 via a pin.

[0051] Reference Figure 4 Each driving frame 342 is sleeved on the corresponding stirring portion 211 and is slidably connected to the corresponding stirring portion 211, and the sliding direction is set to the length direction of the stirring portion 211. One end of each supporting frame 341 is rotatably connected to the corresponding driving frame 342 via a pin, and the other end is rotatably connected to the corresponding scraper frame 31 via a pin to achieve rotational drive of the scraper frame 31.

[0052] Reference Figure 4 and Figure 5 In the initial state, i.e., when the scraper frame 31 is retracted, the scraper frame 31 is located away from the end pivotally connected to the stirring portion 211 and closer to the mounting frame 5. At this point, the main frame 3311 is at the top of its sliding path. When the driving member 32 drives the rotating ring 6 downward, the rotating ring 6 also causes the main frame 3311 to slide. At this time, the elastic force of the elastic member 3313 drives the intermittent frame 3312 downward.

[0053] Reference Figure 4 and Figure 5 During this process, the intermittent frame 3312 drives the transmission frame 332 to move, causing the transmission frame 332 to drive the corresponding driving frame 342 to slide away from the setting frame 5. At this time, the driving frame 342 drives the scraper frame 31 to rotate relative to the stirring part 211 through the support frame 341, causing the scraper frame 31 to gradually approach the inner side wall of the machine body 1 and eventually abut against the inner side wall of the machine body 1.

[0054] Reference Figure 4 and Figure 6 A reinforcement mechanism 8 is also provided on the stirring frame 21. The reinforcement mechanism 8 includes a reinforcement frame 81 and a linkage assembly 82. The linkage assembly 82 includes a linkage gear 821, a transmission gear 822 and a linkage rack 824. In the embodiment of the present application, the number of the reinforcement frame 81, the linkage gear 821, the transmission gear 822 and the linkage rack 824 is set to four, and is arranged one-to-one corresponding to the scraper frame 31.

[0055] Reference Figure 4 and Figure 6 Each linkage gear 821 is disposed within the main body of the stirring frame 21 and is rotationally connected to the stirring frame 21 via a pin. Each transmission gear 822 is coaxially disposed with and fixedly connected to the corresponding linkage gear 821. The number of teeth on each transmission gear 822 is smaller than that on the corresponding linkage gear 821 to minimize slippage of the linkage rack 824.

[0056] Reference Figure 4 and Figure 6 The top of each linkage frame 823 is fixedly connected to the bottom of the extension frame 3314 and is slidably connected to the interior of the installation frame 5. Each linkage frame 823 is provided with tooth grooves on all sides, so that the teeth formed by each tooth groove mesh with the corresponding linkage gear 821. One end of each linkage rack 824 extends into the corresponding stirring portion 211 and is slidably connected to the corresponding stirring portion 211, with the sliding direction being the length direction of the corresponding stirring portion 211. It is also fixedly connected to the corresponding reinforcement frame 81 and meshes with the corresponding transmission gear 822.

[0057] Reference Figure 4 and Figure 6 Each reinforcement frame 81 is located within the corresponding stirring portion 211 and is slidably connected to the inner wall of the corresponding stirring portion 211, with the sliding direction being the length direction of the corresponding stirring portion 211. The sliding path of each reinforcement frame 81 extends outside the corresponding stirring portion 211, and each scraper frame 31 is located on the displacement path of the end of the corresponding reinforcement frame 81, so that the reinforcement frame 81 can be inserted into the corresponding scraper frame 31. A slot is formed at the end of each scraper frame 31 for inserting the reinforcement frame 81.

[0058] Reference Figure 4 、 Figure 5 and Figure 6 In the initial state, the reinforcement frame 81 is located at the end of its sliding path away from the stirring portion 211. When the main frame 3311 drives the intermittent frame 3312 to slide, the extension frame 3314 connected to the main frame 3311 drives one of its linked racks 824 to slide, thereby causing the linked rack 824 to slide through the linked gear 821 and the transmission gear 822, thereby causing the reinforcement frame 81 to slide and gradually approach the scraper frame 31.

[0059] Reference Figure 4 、 Figure 5 and Figure 6 When the intermittent frame 3312 abuts against the abutment portion 51, thereby preventing the intermittent frame 3312 from sliding further, the main frame 3311 continues to slide, causing the extension frame 3314 to continue to slide through the linkage assembly 82, causing the reinforcement frame 81 to continue to approach the reinforcement frame 81. During this process, the scraper frame 31 remains stationary relative to the stirring portion 211, and the elastic member 3313 is compressed. Thereafter, the reinforcement frame 81 continues to slide and is eventually inserted into the groove defined in the bottom of the scraper frame 31, thereby reinforcing the scraper frame 31.

[0060] The principle of implementation of the material-adhesion-preventing mixer of Example 2 of the present application is as follows: when the scraper frame 31 needs to be driven to expand, the driving member 32 drives the rotating ring 6 to move downward, and the rotating ring 6 drives the main frame 3311 to slide together. At this time, the rotating ring 6 drives the intermittent frame 3312 to move downward through the elastic force of the elastic member 3313. During this process, the intermittent frame 3312 drives the transmission frame 332 to move, so that the transmission frame 332 drives the corresponding driving frame 342 to slide away from the setting frame 5. At this time, the driving frame 342 drives the scraper frame 31 to rotate relative to the stirring portion 211 through the support frame 341, thereby causing the scraper frame 31 to gradually approach the inner wall of the machine body 1.

[0061] After the scraper frame 31 abuts the inner wall of the machine body 1, the intermittent frame 3312 abuts the abutment portion 51, preventing the intermittent frame 3312 from sliding further. At this point, the main frame 3311 continues to slide, causing the extension frame 3314 to continue to slide through the linkage assembly 82, causing the reinforcement frame 81 to continue to approach the reinforcement frame 81. During this process, the scraper frame 31 remains stationary relative to the stirring portion 211, and the elastic member 3313 is compressed. Thereafter, the reinforcement frame 81 continues to slide and is ultimately inserted into the groove defined in the bottom of the scraper frame 31, reinforcing the scraper frame 31.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
