Detailed Embodiment

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model provides as Figures 1-5A scraping mechanism for a mixer, as shown, includes a mixer body 1. At the top of the mixer body 1, there is a feed pipe 2 for the entry of materials. At the top of the mixer body 1, there is a scraping mechanism for scraping the inner wall of the feed pipe 2. The scraping mechanism includes a scraping component and a driving component. The scraping component includes a scraping piece and a connecting piece. The scraping piece includes a scraper 3. At the bottom end of the scraper 3, there is a rotating gear 5 for driving the rotation of the scraper 3. The driving component is used to drive the rotation of the rotating gear 5.

[0021] Specifically, the mixer body 1 is an existing model ZYQ-QZ400 type double-shaft mixing mixer. The feed pipe 2 is the feed pipe of the mixer body 1. The feed pipe 2 is frustum-shaped and is connected to the mixer body 1 in a through manner. By pouring materials into the feed pipe 2, they enter the interior of the mixer body 1 for mixing.

[0022] Specifically, the connecting piece includes an insertion block 13. At the top end of the rotating gear 5, there is a connecting seat 4 for connecting the scraper 3. At the top end of the connecting seat 4, there is a slot. The insertion block 13 is inserted into the slot. Inside the insertion block 13, there is a cavity. On one side of the inner wall of the cavity, there is an insertion hole. On one side of the inner wall of the slot, there is a locking hole. Inside both the insertion hole and the locking hole, there is an inserted block 10. On the back of the inserted block 10, there is a fixed connection with a baffle 11. On the back of the baffle 11, there is an elastic block 12 for pushing the baffle 11.

[0023] Furthermore, the scraper 3 is U-shaped. The outer wall of the scraper 3 is treated with a non-stick coating mainly composed of polytetrafluoroethylene. Thus, when the scraper 3 scrapes the materials, the materials are not easily adhered to the surface of the scraper 3. One end of the scraper 3 is attached to the inner wall of the feed pipe 2. The bottom end of the scraper 3 is fixedly connected to the top end of the insertion block 13 by welding. The bottom end of the connecting seat 4 is fixedly connected to the top end of the rotating gear 5 by welding. The size of the insertion block 13 matches the size of the slot. The insertion hole and the locking hole have the same size, which is 1.02 times the size of the inserted block 10. The size of the baffle 11 is 1.2 times the size of the insertion hole. The elastic block 12 is an elastic rubber block and is in a compressed state inside the cavity. By inserting the insertion block 13 into the slot, the inserted block 10 is simultaneously inserted into the insertion hole and the locking hole, and the insertion block 13 can be fixedly connected to the connecting seat 4, thereby fixedly installing the scraper 3 at the top end of the connecting seat 4. When the rotating gear 5 rotates, the rotating gear 5 drives the scraper 3 to rotate synchronously through the connecting seat 4, enabling the scraper 3 to scrape the adhered materials on the inner wall of the feed pipe 2 and making them fall along the feed pipe 2 into the interior of the mixer body 1.

[0024] Specifically, a rotating bearing 6 is sleeved on the outer wall of the bottom of the feed pipe 2, and a rotating gear 5 is sleeved on the outer wall of the rotating bearing 6. The driving assembly includes a motor 9. The output end of the motor 9 is fixedly connected with a driving gear 8. A transmission gear 7 for driving the rotating gear 5 to rotate is arranged on one side of the driving gear 8. The bottom end of the transmission gear 7 is fixedly connected with a mounting column 14. A mounting bearing 15 is sleeved on the outer wall of the bottom of the mounting column 14, and the mounting bearing 15 is arranged on the top end of the mixer body 1.

[0025] Furthermore, a rotating bearing 6 is fixedly sleeved on the outer wall of the bottom of the feed pipe 2. The rotating bearing 6 is a ball bearing. The rotating gear 5 is fixedly sleeved on the outer wall of the rotating bearing 6. Thus, the rotation of the rotating gear 5 can drive the scraper 3 to rotate without affecting the feed pipe 2. The transmission gear 7 and the rotating gear 5 are meshed with each other. The bottom end of the transmission gear 7 and the top end of the mounting column 14 are fixedly connected by welding. The inner wall of the mounting bearing 15 is fixedly sleeved on the outer wall of the bottom of the mounting column 14. The mounting bearing 15 is a ball bearing. However, the height of the outer ring of the mounting bearing 15 is 2-3 mm higher than that of the inner ring. The bottom end of the outer ring of the mounting bearing 15 and the top end of the mixer body 1 are fixedly connected by welding, so as to ensure that the rotation of the mounting column 14 and the transmission gear 7 is not affected. The driving gear 8 and the transmission gear 7 are meshed with each other. A round rod is welded to the bottom end of the driving gear 8. The round rod is fixedly connected with the output end of the motor 9 through a coupling. The bottom end of the motor 9 is fixedly connected with a support plate. The support plate is fixedly welded to the side wall of the mixer body 1. Therefore, when feeding materials through the feed pipe 2, by controlling the start of the motor 9, the driving gear 8 is driven to rotate. The driving gear 8 drives the transmission gear 7, the transmission gear 7 drives the rotating gear 5, the rotating gear 5 drives the connecting seat 4, and the connecting seat 4 drives the scraper 3 to rotate along the feed pipe 2 through the insertion block 13 to scrape the inner wall of the feed pipe 2.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
