When the conveying belt mechanism units are placed, a certain small gap is ensured between two conveying belts on two adjacent conveying belt mechanism units, and the function of the small gap is to prevent the two conveying belts from rubbing in the moving process.

The working principle of the invention is as follows: for convenience of description, the cross-sectional area of the transport belt is set to a1, the moving speed of the transport belt is set to V1, the density of the transport belt is set to P1, and the moving mass of the transport belt per unit time is set to M1, that is, the moving mass of the transport belt per unit time M1 is a 1V 1 ρ 1; under the condition that rho 1 is kept unchanged, the moving mass M1 of the conveying belt in unit time is determined by the cross sectional area A1 of the conveying belt and the moving speed V1 of the conveying belt, namely under the condition that the moving mass M1 of the conveying belt in unit time is kept constant, the smaller the cross sectional area A1 of the conveying belt is, the higher the moving speed V1 of the conveying belt is, on the contrary, the larger the cross sectional area A1 of the conveying belt is, the lower the moving speed V1 of the conveying belt is, in the invention, in order to meet the requirement that goods can be put into one end of a main drive of a conveying belt mechanism unit, the moving of the conveying belt can drive the goods to move, the goods cannot slip phenomenon occurs on the conveying belt and two groups of D-shaped rollers arranged at two ends of a supporting frame, the goods moving into a V-shaped groove between two adjacent conveying belts can smoothly move out of the V-shaped groove, and the moving, in other words, at the position of the V-shaped groove, the speed of the corresponding conveyor belt driven by the main-driven D-shaped roller in the conveyor belt mechanism unit positioned at the rear side of the V-shaped groove is higher than the speed of the corresponding conveyor belt driven by the driven D-shaped roller in the conveyor belt mechanism unit positioned at the front side of the V-shaped groove; under the condition that the power output by the driving mechanisms in all the conveying belt mechanism units to the main-drive D-shaped roller is the same, the moving speed of the conveying belt part positioned at the front end in the same conveying belt mechanism unit is higher than that of the conveying belt part positioned at the rear end, namely the rotating speed of the main-drive D-shaped roller is higher than that of the passively-operated D-shaped roller; in order to meet the above conditions, the driving mechanism is designed, a driving force is provided for the main-driving D-shaped roller through the driving mechanism, the passive-operating D-shaped roller is driven to rotate through the transmission belt, the rotation of the passive-operating D-shaped roller requires the transmission belt to overcome the inherent resistance of the passive-operating D-shaped roller to drive the passive-operating D-shaped roller to rotate, so that the moving speed of the transmission belt at one end of the passive-operating D-shaped roller is smaller than that of the transmission belt at one end of the active-driving D-shaped roller, and the inherent resistance of the passive-operating D-shaped roller is the frictional resistance between the corresponding supporting driving plate and the corresponding semicircular shaping main; from M1 ═ a1 ═ V1 × ρ 1, it can be seen that, with ρ 1 remaining unchanged, V1 increases and a1 decreases, i.e., the cross section of the belt driven by the main-driven D-roller on the lower side of the belt becomes smaller, i.e., a section of the belt on the lower side of the belt is stretched to a greater extent than a section of the belt on the upper side of the belt; according to the invention, by designing the driving mechanism, a driving force is provided for the main-driven D-shaped idler wheels through the driving mechanism, and meanwhile, the stretching degree of a section of transmission belt on the lower side of the transmission belt is greater than that of a section of transmission belt on the upper side of the transmission belt, so that the requirement that goods are placed at one end of the main drive of the transmission belt mechanism unit is met, the goods can be driven to move by the movement of the transmission belt, meanwhile, the transmission belt and two groups of D-shaped idler wheels arranged at two ends of the supporting frame cannot slip, and the goods moving to the V-shaped groove between two adjacent transmission belts can smoothly move out of the V-.

Compared with the traditional conveying belt mechanism technology, the conveying belt designed by the invention is supported by the two D-shaped rollers at the front end and the rear end of the conveying belt, under the action of the D-shaped rollers, the straight surfaces are arranged at the front end and the rear end of the supporting frame on the conveying belt, the conveying belts at the joint of the two adjacent conveying belt mechanism units are in straight surface contact, a V-shaped groove formed at the joint of the two conveying belts is smaller, and the probability that smaller goods are deadly clamped when passing through the V-shaped groove is reduced; meanwhile, the friction strength of the transmission belt in the rear-side transmission belt mechanism unit in two adjacent transmission belt mechanism units in the transmission belt mechanism unit is higher than that of the transmission belt in the rear-side transmission belt mechanism unit, so that when goods pass through the V-shaped groove, the friction force of the rear-side transmission belt on the goods is higher than that of the front-side transmission belt on the goods, and the goods are more easily transmitted from the front-side transmission belt to the rear-side transmission belt; in addition, the moving speed of the conveying belt part at the rear side of the V-shaped groove is higher than that of the conveying belt part at the front side of the V-shaped groove, so that goods can be more easily conveyed from the conveying belt at the front side to the conveying belt at the rear side. According to the invention, the conveying belt is supported by the D-shaped roller, so that the contact area between the conveying belt and the roller is not reduced by replacing a large roller with the D-shaped roller.

According to the invention, the conveying belt 4 is supported by the D-shaped roller, so that the contact area between the conveying belt 4 and the roller is not reduced by replacing a large roller with the D-shaped roller.

In the invention, one end of the supporting driving plate 12 is connected with the rubber ring 13 through the fixing sleeve 21, the rubber ring 13 has elasticity, the rubber ring 13 can extrude the supporting driving plate 12 to enable the other end of the supporting driving plate 12 to be tightly attached to the semicircular shaped column 14, the lengths of all the supporting driving plates 12 arranged between the rubber ring 13 and the semicircular shaped column 14 are the same, and the semicircular shaped column 14 is in a semi-cylindrical shape, so that the rubber ring 13 is also in a semi-cylindrical shape under the action of the semicircular shaped column 14 and the supporting driving plate 12, the semicircular shaped column 14 is fixed, the overall shape of the rubber ring 13 cannot be changed in the rotating process of the rubber ring 13, the straight section of the rubber ring 13 is always in a straight surface, namely, the appearance of the D-shaped roller 26 cannot be changed along with the movement of the transmission belt 4.

The driving ring 11 belonging to the active driving D-shaped roller 26 of the invention provides driving force for the driving ring through the driving mechanism 2, and the driving ring 11 rotates under the guiding action of the supporting cylindrical groove 19 opened on the first fixing plate 5 and the guiding ring 17 opened on the second fixing plate 9 after receiving the driving force; the driving ring 11 rotates to drive the supporting driving plate 12 matched with the guide groove 22 to rotate around the axis of the driving ring 11 through the guide groove 22 opened on the driving ring 11; the supporting driving plate 12 rotates to drive the rubber ring 13 to rotate; the rubber ring 13 provides a driving force to the conveyor belt 4.

According to the invention, under the action of the two D-shaped rollers, the front end and the rear end of the support frame 25 on the transmission belt 4 are provided with straight surfaces, the transmission belt 4 at the joint of the two adjacent transmission belt mechanism units 1 is in straight surface contact, and a V-shaped groove formed at the joint of the two transmission belts 4 is smaller, so that smaller goods are prevented from being deadly clamped when passing through the V-shaped groove. When the conveyor belt mechanism units 1 are placed, a certain small gap is ensured between two conveyor belts 4 on two adjacent conveyor belt mechanism units 1, and the function of the gap is to prevent the two conveyor belts 4 from rubbing in the moving process.

The working principle of the invention is as follows: for convenience of description, the cross-sectional area of the conveying belt 4 is set to a1, the moving speed of the conveying belt 4 is set to V1, the density of the conveying belt 4 is set to ρ 1, and the moving mass of the conveying belt 4 per unit time is set to M1, that is, the moving mass of the conveying belt 4 per unit time is set to M1 ═ a1 × V1 × ρ 1; under the condition that rho 1 is kept unchanged, the mass M1 moving in unit time of the conveying belt 4 is determined by the cross sectional area A1 of the conveying belt 4 and the moving speed V1 of the conveying belt 4, namely under the condition that the mass M1 moving in unit time of the conveying belt 4 is kept constant, the cross sectional area A1 of the conveying belt 4 is smaller, the moving speed V1 of the conveying belt 4 is larger, on the contrary, the cross sectional area A1 of the conveying belt 4 is larger, and the moving speed V1 of the conveying belt 4 is smaller The moving speed of the belt conveyor mechanism unit 1 is higher than that of the belt conveyor mechanism unit 1 at the front side of the V-shaped groove, namely the moving speed of the belt conveyor mechanism unit 1 at the rear side of the V-shaped groove is higher than that of the belt conveyor mechanism unit 1 at the front side of the V-shaped groove; under the condition that the power output by the driving mechanisms in all the conveying belt mechanism units 1 to the main-driving D-shaped roller is the same, the moving speed of the part, positioned at the front end, of the conveying belt 4 in the same conveying belt mechanism unit 1 is higher than that of the part, positioned at the rear end, of the conveying belt 4, namely the rotating speed of the main-driving D-shaped roller is higher than that of the passively-operating D-shaped roller; in order to meet the above conditions, the driving mechanism 2 is designed, the driving mechanism 1 provides a driving force for the main-driving D-shaped roller, the passive-operating D-shaped roller is driven to rotate by the transmission belt 4, and the rotation of the passive-operating D-shaped roller requires the transmission belt 4 to overcome the inherent resistance of the passive-operating D-shaped roller to drive the passive-operating D-shaped roller to rotate, so that the moving speed of the transmission belt at one end of the passive-operating D-shaped roller is lower than that of the transmission belt 4 at one end of the active-driving D-shaped roller; from M1 ═ a1 ═ V1 × ρ 1, it can be seen that, with ρ 1 kept constant, V1 increases and a1 decreases, i.e., the cross section of the belt 4 driven by the main-driven D-roller on the lower side of the belt 4 becomes smaller, i.e., the length of the belt 4 on the lower side of the belt 4 is stretched to a greater extent than the length of the belt 4 on the upper side of the belt 4; according to the invention, by designing the driving mechanism 2, a driving force is provided for the main-driven D-shaped idler wheels through the driving mechanism 2, and meanwhile, the stretching degree of a section of transmission belt 4 on the lower side of the transmission belt 4 is greater than that of a section of transmission belt 4 on the upper side of the transmission belt 4, so that the requirement that goods are placed at one end of the main drive of the transmission belt mechanism unit 1 is met, the goods can be driven to move by the movement of the transmission belt 4, meanwhile, the phenomenon of slipping does not occur between the transmission belt 4 and two groups of D-shaped idler wheels arranged at two ends of the supporting frame 25, and the goods moving to the V-shaped groove between two adjacent transmission belts 4 can be.

The working process of the invention is as follows: when the conveying mechanism designed by the invention is used, goods are placed on the conveying belt 4 in the use process, and when small goods pass through the V-shaped groove between two adjacent conveying belt mechanism units 1, on one hand, the V-shaped groove formed at the joint of the two conveying belts 4 is reduced through the two D-shaped rollers 26, so that the probability that the small goods are stuck when passing through the V-shaped groove is reduced; meanwhile, the friction strength of the transmission belt 4 in one transmission belt mechanism unit 1 positioned at the rear side in two adjacent transmission belt mechanism units 1 in the transmission belt mechanism unit 1 in the transmission belt 4 mechanism designed by the invention is greater than that of the transmission belt 4 in the next transmission belt mechanism unit 1, so that when goods pass through the V-shaped groove, the friction force of the transmission belt 4 positioned at the rear side to the goods is greater than that of the transmission belt 4 positioned at the front side to the goods, and the goods are more easily transmitted from the transmission belt 4 at the front side to the transmission belt 4 at the rear side; moreover, the moving speed of the conveyor belt 4 at the front end of the conveyor belt 4 is higher than that of the conveyor belt 4 at the rear end of the conveyor belt 4 at the V-shaped groove, so that goods can be more easily conveyed from the conveyor belt 4 at the front side to the conveyor belt 4 at the rear side.
