Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-5 The protective mechanism shown herein and its synthetic leather internal mixer include a synthetic leather internal mixer 1, which is used to pressurize and melt raw materials. A feed pipe 2 is fixedly installed on the front of the synthetic leather internal mixer 1. The feed pipe 2 is arranged in an L-shape and is used to add raw materials into the synthetic leather internal mixer 1. The raw materials are added into the interior of the synthetic leather internal mixer 1 through the feed pipe 2.

[0022] The feed inlet 3 is located at the top of the feed pipe 2 and is used to add raw materials into the inner cavity of the feed pipe 2. The feed inlet 3 is funnel-shaped and the material is added into the inner cavity of the feed pipe 2 through the feed inlet 3, which facilitates the addition of material.

[0023] A protective device 4 is provided on the feed inlet 3 to seal and protect the top of the feed pipe 2. The protective device 4 is used to seal the opening at the top of the feed pipe 2 to prevent impurities from entering the inner cavity of the feed pipe 2 and contaminating the raw materials.

[0024] The protective device 4 includes a connecting pipe 41, which is square-tube shaped and located at the top of the feed pipe 2. The top end of the connecting pipe 41 is fixedly connected to the bottom end of the feed inlet 3. The inner cavity of the connecting pipe 41 is slidably inserted into the top of the feed pipe 2, and the inner wall of the connecting pipe 41 is in contact with the outer wall of the feed pipe 2. The feed inlet 3 is slidably installed on the top of the feed pipe 2 through the connecting pipe 41, causing the feed inlet 3 to slide on the top of the feed pipe 2. Two protective plates 42 are symmetrically arranged at the top of the inner cavity of the feed inlet 3. The protective plates 42 are used to close the top end of the feed pipe 2. The protective plates 42 move together with the feed inlet 3. Fixed shafts 43 are fixedly connected to both sides of the top of the protective plates 42 for mounting the protective plates. 42. The top of the protective plate 42 rotates around the fixed shaft 43. One end of the fixed shaft 43 is rotatably connected to the mounting block 44. The fixed shaft 43 is fixedly connected to the inner wall of the feed inlet 3 through the mounting block 44. The protective plate 42 is installed in the inner cavity of the feed inlet 3. One end of the mounting block 44 is fixedly connected to the inner wall of the feed inlet 3. The mounting block 44 is set at the top of the inner wall of the feed inlet 3. By moving the feed inlet 3 upward, the connecting pipe 41 slides upward on the top of the feed pipe 2. The top of the protective plate 42 moves upward with the feed inlet 3. The top of the protective plate 42 rotates around the fixed shaft 43. As the feed inlet 3 moves, the outer wall of the protective plate 42 rotates to a position that fits against the inner wall of the feed inlet 3, releasing the protective plate 42 from the sealing of the feed pipe 2.

[0025] Installation devices 5 are provided on both sides of the connecting pipe 41 for installing and connecting the connecting pipe 41 with the feed pipe 2. The installation devices 5 are used to ensure the stable movement of the feed inlet 3 and the connecting pipe 41.

[0026] The mounting device 5 includes two connecting rods 51, which connect the connecting pipe 41 and the feed pipe 2. One end of the connecting rod 51 is fixedly connected to a connecting shaft 1, and the other end of the connecting rod 51 is rotatably connected to a fixing block 52 through the connecting shaft 1. Both ends of the connecting shaft 1 are rotatably connected to fixing blocks 52. The fixing blocks 52 are used to install the connecting shaft 1. Two fixing blocks 52 are fixedly connected to the bottom end of the connecting pipe 41, and the other two fixing blocks 52 are fixedly connected to the outer wall of the feed pipe 2.

[0027] A connecting block 53 is provided between the two connecting rods 51. The two connecting rods 51 are connected at opposite ends through the connecting block 53. Both ends of the connecting block 53 are fixedly connected to the connecting shaft 2. The two ends of the connecting shaft 2 are rotatably connected to the inner wall of one end of the connecting rod 51. The two ends of the connecting block 53 are rotatably connected to one end of the connecting rod 51 through the connecting shaft 2. One end of the two connecting rods 51 is rotatably connected through the connecting block 53, which facilitates the rotation and folding of the two connecting rods 51. A bolt 54 is threaded through one of the connecting rods 51. The bolt 54 rotates with one of the connecting rods 51. One end of the bolt 54 is slidably connected to the outer wall of the feed pipe 2. By rotating and loosening the bolt 54, the fixing of one of the connecting rods 51 is released. One end of the two connecting rods 51 rotates around the connecting block 53. The top of one of the connecting rods 51 drives the connecting pipe 41 to slide downward, thereby rotating and folding the two connecting rods 51.

[0028] The working principle of this utility model is as follows: By moving the feed inlet 3 upward, the connecting pipe 41 slides upward at the top of the feed pipe 2. The top of the protective plate 42 moves upward along with the feed inlet 3. The top of the protective plate 42 rotates around the fixed shaft 43. As the feed inlet 3 moves, the outer wall of the protective plate 42 rotates to a position where it fits against the inner wall of the feed inlet 3, releasing the protective plate 42 from sealing the feed pipe 2. When the feed inlet 3 slides downward, the bottoms of the two protective plates 42 move towards each other and move to the top of the feed pipe 2 to seal the opening. At the same time, by rotating and loosening the bolt 54, the fixing of one of the connecting rods 51 is released. One end of the two connecting rods 51 rotates around the connecting block 53. The top of one of the connecting rods 51 drives the connecting pipe 41 to slide downward, rotating and folding the two connecting rods 51 to ensure the stability of the connecting pipe 41 and the feed inlet 3, facilitating the movement of the connecting pipe 41 and the addition of raw materials to the feed pipe 2.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
