[0002] Belt conveyors, also known as belt conveyors, are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, and food for assembly, testing, debugging, packaging, and transportation of objects. Belt conveyors, also known as belt conveyors or belt conveyors, are economical logistics conveying equipment that are indispensable for rhythmic assembly lines. Belt conveyors can be divided into heavy-duty belt conveyors such as mining belt conveyors and light-duty belt conveyors such as those used in electronic plastics, food and light industry, chemical and pharmaceutical industries according to their conveying capacity.

[0004] However, the belt conveyor safety protection device has the following disadvantages:

[0005] (1) After long-term use, the belt becomes loose due to its own ductility, affecting the transmission efficiency between the roller and the belt, resulting in a waste of kinetic energy. At the same time, when transporting heavy objects, the objects squeeze the belt, causing the belt to be over-tightened, which may cause the belt to burst. There is a lack of structure to adjust the tightness of the belt.

[0006] (2) When transporting heavy items on a belt conveyor, the long-term pressure of the items on the rollers will cause the rollers to deform and lose the effect of supporting the belt, causing the belt to sink and lack of structure to protect the rollers. Utility Model Content

[0028] By setting the support plate 3, a driving motor for driving the transmission wheel 2 to rotate is set on the side of the support plate 3, and the support plate 3 is fixedly connected to the top surface of the slider 41, so that the tightness of the belt 1 can be adjusted conveniently and quickly;

[0029] See also Figure 2 The adjusting assembly 4 includes a slider 41 fixedly connected to the bottom surface of the support plate 3, a threaded hole is provided on the side of the slider 41, a screw rod 42 is threadedly connected to the inside of the threaded hole, the slider 41 is slidably connected to the inside of the slide groove 43, both ends of the slide groove 43 are fixedly connected to the limit plate 44, the side of the limit plate 44 is provided with a rotating hole matching the screw rod 42, one end of the screw rod 42 is fixedly connected to a screw block 8 for convenient force, the other end of the screw rod 42 is sleeved inside the bearing 9, and the bearing 9 is fixedly connected to the side of one of the limit plates 44;

[0030] By setting the bearing 9, when the screw rod 42 rotates inside the rotating hole opened on the side of the limit plate 44, the bearing 9 provides support for the rotating screw rod 42 to prevent one end of the screw rod 42 from being deformed during long-term use and affecting the normal sliding of the slider 41; at the same time, the limit plates 44 are fixed at both ends of the slide groove 43 to effectively prevent the slider 41 from excessive movement and falling off;

[0031] See also Figure 3 The side of the upper arc plate 73 is fixedly connected with a protrusion, and the side of the lower arc plate 74 is provided with a slide bar, and the inside of the slide bar is slidably connected with a matching protrusion;

[0032] By setting the protrusions, when the upper arc plate 73 moves on the inner wall of the lower arc plate 74, the protrusions set on the side of the upper arc plate 73 move synchronously inside the sliding strip on the side of the lower arc plate 74 to limit the upper arc plate 73, thereby preventing the upper arc plate 73 from deflecting when moving up and down, thereby affecting the compression and rebound effect of the spring 76;

[0033] See also Figure 4 The top surface of the support plate 10 is provided with a plurality of threaded holes in a rectangular array, and the internal threads of the threaded holes are connected with a universal wheel 11 for easy movement, and a brake structure is provided inside the universal wheel 11;

[0035] In the utility model, the working steps of the device are as follows:

[0036] First, when the tightness of the belt 1 needs to be adjusted, the screw block 8 can be turned to drive the screw rod 42 fixed on the side to rotate inside the rotating holes opened on the sides of the two limit plates 44, and the slider 41 threadedly connected to the surface of the screw rod 42 moves inside the slide groove 43, so that the support plate 3 fixed on the top surface of the slider 41 moves, and the belt 1 installed on the side of the support plate 3 through the transmission wheel 2 is stretched or shortened accordingly, thereby avoiding the belt 1 from being loosened due to the ductility of the belt 1 itself after long-term use of the belt conveyor, affecting the transmission efficiency between the transmission wheel 2 and the belt 1, and causing kinetic energy waste; at the same time, it is avoided that when transporting heavier objects, the objects squeeze the belt 1, causing the belt 1 to be over-tightened, resulting in the belt 1 bursting The danger of, finally, when conveying heavier objects, the heavy objects are placed on the surface of belt 1, and the rollers 5 inside belt 1 are pressed downward by force. The connecting plates 71 fixed at both ends of the rollers 5 by support rods 6 are also forced to move downward. The connecting plates 71 squeeze the top plates 72 below the two ends. When the top plates 72 move downward, they squeeze the springs 76. During the compression of the springs 76, the squeezing force of the heavy objects on the rollers 5 will be buffered by energy absorption to avoid damage to the rollers 5. At the same time, the screw 771 can be turned to move the adjusting plate 772 threaded on its surface downward. The adjusting plate 772 squeezes the spring 76, so that the elastic strength of the spring 76 is adjusted to meet the protection requirements for the rollers 5 when transporting objects of different weights.
