[0022] See also Figure 1-4The utility model provides an embodiment of a flame retardant raw material belt conveyor, comprising a support frame 1, a plurality of rollers 3 are rotated at equal intervals on the inner side wall of the support frame 1, and a conveyor belt 2 is wrapped around the outer surface of the rollers 3. The two inner side walls of the support frame 1 close to the rollers 3 are fixed with mounting seats 4 by bolts, and the ends of the mounting seats 4 are clamped with end covers 5. The middle of the mounting seats 4 is provided with a second slot 11 for the rollers 3 to be plugged in, and a third slot 14 is provided on the inner side wall of the end cover 5. The two mounting seats 4 and the end cover 5 are made of plastic. The outer size of one end of the mounting seat 4 is adapted to the inner size of the third slot 14, which improves the stability of the end cover 5. A fourth slot 15 is provided in the middle of the end cover 5 and is connected to the third slot 14. Two sliders 16 are fixed on the inner side wall of the third slot 14, and the slider 16 is fixedly connected to the end cover 5 to form an integrated structure. The inner wall of the fourth slot 15 A card slot three 17 is provided on it, and a sealing ring 18 is clamped inside the card slot three 17. The sealing ring 18 is made of rubber and is in a circular ring shape. The internal size of the sealing ring 18 is adapted to the external size of the two ends of the roller shaft 3. Two card slots 12 are provided on the surface of the mounting seat 4, and two card slots 13 are symmetrically provided on the side wall of the mounting seat 4, which are connected to the card slot 12 in sequence. The external size of the slider 16 is adapted to the internal size of the card slot 12 and the card slot 2 13, which improves the convenience of installing the end cover 5. The slider 16 is clamped inside the card slot 12 and the card slot 2 13 in sequence, which improves the convenience of installing the end cover 5. The two ends of the roller shaft 3 pass through the slot four 15, the slot three 14 and the slot two 11 in sequence, so that the mounting seat 4, the end cover 5 and the sealing ring 18 are sleeved on the two ends of the roller shaft 3, which improves the sealing performance of the connection between the roller shaft 3 and the support frame 1, thereby improving the rotation life of the roller shaft 3.

[0023] Two notches 6 are symmetrically provided at the top of the support frame 1, and a number of U-shaped covers 8 are slidably connected to the inside of the notches 6. The U-shaped covers 8 are made of plastic, which reduces the overflow of dust. A number of groups of support legs 10 are fixed at equal intervals at the bottom of the support frame 1, which improves the stability of the support of the support frame 1.

[0024] The conveyor belt 2 is made of silicone and has good corrosion resistance. Several groups of blocks 7 are fixedly connected to the surface of the conveyor belt 2. The blocks 7 are all V-shaped and fixedly connected to the conveyor belt 2 to form an integrated structure to prevent the raw materials from slipping, thereby improving the stability of the flame retardant raw material transportation. A servo motor 9 is fixedly provided on the side wall of the support frame 1 by bolts. The output end of the servo motor 9 is fixed to the end of the roller 3 through a coupling. Starting the servo motor 9 can drive the roller 3 to rotate. The conveyor belt 2 rotates synchronously with the roller 3 under the action of friction, thereby realizing the transportation of flame retardant raw materials.

[0025] Working principle: When using this flame retardant raw material belt conveyor, the operator first connects the external power supply, places the flame retardant raw material on the surface of the conveyor belt 2, starts the servo motor 9 to drive the roller 3 to rotate, and the conveyor belt 2 rotates synchronously with the roller 3 under the action of friction, which can realize the transportation of flame retardant raw materials. When dust is generated during transportation, the two ends of the roller 3 pass through the slot 4 15, the slot 3 14 and the slot 2 11 in sequence, so that the mounting seat 4, the end cover 5 and the sealing ring 18 are set on the two ends of the roller 3 to seal. The ring 18 is made of rubber, which improves the sealing of the connection between the roller shaft 3 and the support frame 1, reduces dust pollution, and thus increases the rotation life of the roller shaft 3. By rotating the end cover 5, the slider 16 can slide out of the second slot 13 and the first slot 12 in turn, thereby separating the mounting seat 4 and the slot four 15 to facilitate the filling of lubricant into the interior of the second slot 11. The lubricant is a prior art and will not be described here. The slider 16 is then clamped in the interior of the slot one 12 and the slot two 13 in turn to improve the convenience of connecting the mounting seat 4 and the end cover 5.

[0026] Secondly, when several U-shaped covers 8 are slidably connected to the inside of the slot 1 6 in sequence, the top of the conveyor belt 2 can be covered, which can reduce dust overflow and avoid contaminating the connection between the outer wall of the support frame 1 and the roller 3.
