Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] A roller support for a belt conveyor, such as Figure 1-Figure 4 As shown, it includes a bracket 1, a side frame 2, a first motor 3, a belt 4, a compression spring 5, a fixed block 6, a tensioning wheel 7, a printing mechanism 8 and an emergency stop mechanism 9. Six supporting feet are provided at the lower part of the bracket 1 for easy support. A distribution box is provided on the left side of the front of the bracket 1, and the distribution box is connected to the side frame 2 on the front side to provide power. The bracket 1 is connected to two front and rear side frames 2. The left part of the front side frame 2 is connected to the first motor 3. Four rollers arranged on the left and right are rotatably connected to the side frame 2. The leftmost roller is connected to the output shaft of the first motor 3. Belts 4 are wound around the rollers, and the belts 4 are made of rubber. Fixed blocks 6 are slidably connected to the inner sides of the middle parts of the side frames 2. Tensioning wheels 7 are rotatably connected between the fixed blocks 6. Compression springs 5 ​​are connected between the side frames 2 and the fixed blocks 6. A printing mechanism 8 for extruding textures is provided between the right parts of the side frames 2, and an emergency stop mechanism 9 for emergency stopping of the machine is provided between the left parts of the side frames 2.

[0021] like Figure 1 and Figure 3As shown, the printing mechanism 8 includes a second motor 81, a printing roller 82 and a pressure plate 83. The second motor 81 is connected to the right part of the front side frame 2, and the printing roller 82 is rotatably connected between the lower right side of the side frame 2. The printing roller 82 is connected to the output shaft of the second motor 81. A pressure plate 83 is connected between the lower right side of the side frame 2, and the pressure plate 83 is located on the upper side of the printing roller 82.
