In the specific implementation: as shown in figures 1-3, a snack vending machine capable of preventing collision damage during discharging comprises a vending machine body 1 provided with a discharging bin 101 at the bottom, wherein spring spiral channels 2 which are uniformly distributed are arranged inside the vending machine body 1, a discharging mechanism 4 capable of preventing collision damage of goods during discharging is further arranged inside the vending machine body 1, the discharging mechanism 4 comprises a conveying belt 401 with the lower end penetrating into the discharging bin 101 and the top vertically extending, two driving rollers 402 which are respectively connected with the vending machine body 1 and the discharging bin 101 in a rotating manner are rotatably connected to the inner surface of the conveying belt 401, a servo motor 403 which is fixedly connected with the vending machine body 1 is fixedly connected to one end of the driving roller 402 at the upper end, bearing plates 404 which are annularly distributed are fixedly connected to the surface of the conveying belt 401 at equal intervals, and an included angle exists between the bearing plates 404 and the horizontal plane, and the top of carrier plate 404 is disposed toward spring coil lane 2. Go out the interior diapire of feed bin 101 and be convex, the inner wall that goes out feed bin 101 is provided with the protection sponge.

When the goods inside the spring spiral goods passage 2 are pushed onto the loading plate 404, the servo motor 403 can smoothly convey the goods to the discharging bin 101 through the driving roller 402 and the conveyor belt 401. Compared with the existing discharging mode, the discharging mechanism 4 can convey goods into the discharging bin 101 at a constant speed, the falling height and kinetic energy of the goods can be greatly reduced, the probability of collision damage of the goods during discharging is reduced, and the protection effect is achieved, the included angle between the bearing plate 404 and the horizontal plane is ten degrees, the opening of the included angle between the bearing plate 404 close to the spiral spring goods channel 2 and the conveyor belt 401 is upward, the probability that the goods slide off from the bearing plate 404 can be reduced, the goods can be conveyed stably by the discharging mechanism 4, and the good anti-skidding effect is achieved;

as shown in fig. 2 and 3, a mounting groove 405 is formed on the top surface of the bearing plate 404, a pressure sensor 406 is fixedly connected in the mounting groove 405, an output end of the pressure sensor 406 is electrically connected with an input end of the controller 3, an input end of the servo motor 403 is electrically connected with an output end of the controller 3 in the vending machine body 1, when goods fall on the bearing plate 404, the goods press the pressure sensor 406, so that the pressure sensor 406 outputs a pressure signal to the controller 3, the controller 3 controls the servo motor 403 to rotate in a corresponding direction according to a driving instruction preset in the controller 3 by a worker, manual adjustment by a user is not required, so that the blanking mechanism 4 can automatically discharge the goods, when the goods are separated from the bearing plate 404, the pressure sensor 406 loses pressure, the pressure sensor 406 can stop sending a signal to the controller 3, and the controller 3 controls the servo motor 403 to rotate according to a reset instruction preset in the controller by the worker, the servo motor 403 resets all the loading plates 404 through the driving roller 402 and the conveyor belt 401 to ensure that the loading plates 404 can catch the goods at a constant speed when the goods move out of the spring spiral goods passage 2, thereby achieving a good self-resetting effect. Inner wall one side of mounting groove 405 articulates there is the crimping behind being used for accepting the goods pressure sensor 406's clamp plate 407, clamp plate 407 and mounting groove 405's size phase-match, when the goods falls on loading board 404, the goods just contacts with clamp plate 407 very easily for clamp plate 407 extrusion pressure sensor 406 need not worry the unable extrusion pressure sensor 406's of goods that falls on loading board 404 surface the condition, with guarantee unloading mechanism 4 can normal operating, thereby improved unloading mechanism 4's practicality. The bottom surfaces of two sides of the pressing plate 407 are connected with one end of a spring 408 with a V-shaped cross section, the other end of the spring 408 is fixedly connected with the mounting groove 405, and the elasticity of the spring 408 is not large. After the goods is separated from the pressing plate 407, the elastic piece 408 can push back the pressing plate 407, so that the pressing plate 407 is separated from the pressure sensor 406, the blanking mechanism 4 can be reset by the controller 3, manual adjustment by workers is not needed, a good self-resetting effect is achieved, meanwhile, the elastic piece 408 can also apply a resistance to the pressing plate 407, and when the goods do not fall onto the surface of the bearing plate 404, the probability that the pressing plate 407 mistakenly touches the pressure sensor 406 is prevented, a baffle 409 is fixedly connected to the end of the length direction of the bearing plate 404, the baffle 409 is perpendicular to the bearing plate 404, and the baffle 409 can reduce the probability that the goods slide down from the surface of the bearing plate 404 in the conveying process, so that the goods can be conveyed into and out of the feed bin 101 smoothly.

When the utility model is used, when goods in the spring spiral goods channel 2 is pushed to the pressure plate 407 on the bearing plate 404, the goods presses the pressure plate 407 downwards, the pressure plate 407 presses the pressure sensor 406 downwards, so that the pressure sensor 406 outputs a pressure signal to the controller 3, the controller 3 controls the servo motor 403 to rotate towards the corresponding direction according to a driving instruction preset in the controller 3 by a worker, the servo motor 403 drives the upper end driving roller 402 to rotate, the upper end driving roller 402 drives the conveyor belt 401 to rotate, the conveyor belt 401 drives the bearing plate 404 to move, the bearing plate 404 can drive the goods to move downwards stably, when the bearing plate 404 passes by the vicinity of the lower end driving roller 402, the conveyor belt 401 can drive the bearing plate 404 to rotate along the lower end driving roller 402, at the moment, the goods 404 drives the goods to rotate, so that the gravity center of the bearing plate is continuously adjusted, when the gravity center of the goods is not on the bearing plate 404, the goods can fall under the influence of gravity, so that the goods fall into the discharging bin 101. Compare in current ejection of compact mode, this unloading mechanism 4 can be with the inside of goods at the uniform velocity transport feed-in discharge bin 101, can cut down the height and the kinetic energy of goods whereabouts by a wide margin to reduce the impaired probability of goods, simultaneously because the existence of unloading mechanism 4, unloading mechanism 4 also can prevent lawless persons from stealing the goods inside vending machine body 1 through discharge bin 101, thereby improves the factor of safety of vending machine. It should be noted that the vending machine should sell products with a certain weight, such as biscuits, cakes and the like. The controller and the pressure sensor are mature and commercially available products, and the manufacturer can select the corresponding model according to the size and the layout of the vending machine.
