DETAILED DESCRIPTION

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0017] Example 1 See also Figure 1-7 , a box-dropping machine, comprising a frame 1, a cardboard feeding device 3, a material storage device 4, a noodle conveying device 8, a cardboard bending mechanism 9 and a cardboard conveying device 6; The noodle conveyor 8 is disposed at the bottom end of the frame 1, and the noodle conveyor 8 passes through the frame 1 along the transmission direction. The noodle conveyor 8 is used to transport the quantitative noodles, and the distances between the noodles on the noodle conveyor 8 are the same. In this way, it is convenient for the paperboard 5 to be discharged in the subsequent process so as to correspond to the noodles.

[0018] The storage device 4 is used to store the paperboard 5 covering the noodles. Figure 2 The cardboard 5 is arranged in an inclined manner in the storage device 4, and slides toward the discharge end of the storage device 4 by the component force of its own gravity. The discharge end of the storage device 4 is the position where the vacuum suction cup 302 faces when the feeding rod 301 rotates to the position of the storage device 4. The storage device 4 is located on one side of the cardboard unloading device 3. The storage device 4 and the cardboard unloading device 3 are both located above the cardboard conveying device 6. The cardboard unloading device 3 is provided with a plurality of vacuum suction cups 302. The cardboard 5 in the cardboard conveying device 6 is transported to the cardboard conveying device 6 by the cardboard unloading device 3.

[0019] A driving device 2 is provided on the side of the cardboard blanking device 3 , and the driving device 2 drives a plurality of vacuum suction cups 302 in the cardboard blanking device 3 to rotate.

[0020] The cardboard unloading device 3 includes an outer shell, which is in a hollow cylindrical shape. A disc 203 is rotatably connected inside the outer shell. An output shaft is fixedly connected to the output end of the driving device 2. The output shaft extends into the outer shell and is fixedly connected to the disc 203 on the output shaft inside the outer shell. A driving gear 201 is fixedly connected to the outer shell. When the cardboard 5 is unloading, the driving device 2 drives the disc 203 to rotate.

[0021] The disk 203 is rotatably connected to three driven gears 202, which are located outside the driving gear 201 and arranged in an equilateral triangle. When the disk 203 rotates, it drives the multiple driven gears 202 to rotate around the driving gear 201. During the rotation of the driven gears 202, they will also rotate due to the driving gear 201.

[0022] The disc 203 is also provided with three delivery shafts 205, which are respectively arranged at positions close to the outside of the three driven gears 202. The delivery shafts 205 are rotatably connected to the disc 203, and the outer wall of the delivery shaft 205 is fixedly connected with a feeding gear 206, which is meshed with the driven gear 202. The delivery shaft 205 is also fixedly connected with a feeding rod 301 in its setting direction, and one end of the feeding rod 301 away from the delivery shaft 205 is fixedly connected to the vacuum suction cup 302. The delivery shaft will also rotate with the rotation of the disc 203, and because the driven gear 202 rotates, it will also drive the delivery shaft 205 to rotate. When the delivery shaft 205 rotates, it drives the feeding rod 301 and the vacuum suction cup 302 to rotate. When the vacuum suction cup 302 rotates, its suction end will face the discharge end of the storage device 4 and the conveying chain 602, and under the control of the sensor, the cardboard 5 in the storage device 4 is transferred to the conveying chain 602. The sensor is a prior art and will not be described in detail.

[0023] When the vacuum suction cup 302 rotates to the position of the material storage device 4, its suction end is directly opposite to the material storage device 4. The suction or retraction of the vacuum suction cup 302 is controlled by a sensor, which is arranged at the position of the feeding rod 301, and the sensor is used to detect the position of the feeding rod 301. When the feeding rod 301 moves to a position close to the material storage device 4, the suction end of the vacuum suction cup 302 is directly opposite to the discharge end of the material storage device 4, and the suction end will contact the cardboard 5, and then the vacuum suction cup 302 will suck the cardboard through the control of the sensor. Since the cardboard 5 has elasticity under certain circumstances, it can undergo slight deformation. When the vacuum suction cup 302 sucks the cardboard 5 and moves it, the cardboard 5 will deform and then separate from the material storage device 4. After the cardboard 5 is deformed and separated from the material storage device 4, it will deform back to its original state.

[0024] The adsorption end of the vacuum suction cup 302 can adsorb the cardboard 5 in the storage device 4. When the vacuum suction cup 302 rotates to the top of the cardboard conveying device 6, its adsorption end is in a state of facing the cardboard conveying device 6. After the vacuum suction cup 302 adsorbs the cardboard 5, during the revolution of the feeding rod 301, it will rotate from the position close to the storage device 4 to the top of the cardboard conveying device 6. When the vacuum suction cup 302 moves to the top of the cardboard conveying device 6, the sensor will release the adsorption effect on the cardboard 5 by sensing the position, so that the cardboard falls on the cardboard conveying device 6, and the cardboard 5 is sequentially transported in this way.

[0025] This embodiment is a process of transporting the cardboard 5 in the storage device 4 to the conveyor chain 602.

[0026] Example 2 The paperboard conveying device 6 is located above the noodle conveying device 8 and is connected to the frame 1. The paperboard conveying device 6 includes a guide bar, a conveying chain 602 with a conveying function is arranged between the two guide bars, a plurality of pushers 603 are arranged on the conveying chain 602, the spacing between the plurality of pushers 603 is the same, the distance between the pushers 603 is greater than the length of the paperboard 5, and a guide plate 601 is arranged on the opposite side of the two guide bars, and the distance between the two guide plates 601 corresponds to the width of the paperboard 5.

[0027] As described above, the cardboard 5 is sucked by the vacuum suction cup 302 and grabbed onto the cardboard conveying device 6, wherein the cardboard 5 falls onto the conveying chain 602 with a conveying function, and the position where the cardboard 5 falls is also between the two pushing members 603, and the cardboard 5 is moved by the action of the pushing members 603.

[0028] Taking the conveying direction of the noodle conveying device 8 as the positive direction, the paperboard conveying device 6 further comprises a conveying mechanism 7, which is composed of two symmetrically arranged conveying bars 701, the two conveying bars 701 are arranged in an up-and-down manner, and a plurality of transmission shafts 703 are rotatably connected to the conveying bars 701, and the plurality of transmission shafts 703 are synchronously rotated by a chain. Two symmetrically arranged rotating wheels 702 are fixedly connected to the transmission shaft 703. The symmetrical rotating wheels 702 correspond to the symmetrically arranged guide plates 601 respectively, and the rotating wheels 702 are arranged on the rear side of the guide plates 601. The rotating wheels 702 transmit the cardboard between the pushing members 603 by rotating, wherein the transmission direction is the positive direction. Two symmetrically arranged supporting cross plates are arranged between the two transmission bars 701, and the supporting cross plates are used to support the cardboard 5 being transmitted.

[0029] When the rotating wheel disc 702 rotates, the cardboard 5 is transported to between the two rotating wheel discs 702 by the conveying chain 602 , and then the cardboard 5 is moved forward between the two rotating wheel discs 702 by friction.

[0030] This embodiment is a part of transporting the cardboard on the conveying chain 602 to the cardboard bending mechanism 9 Example 3 The cardboard bending mechanism 9 is arranged at the rear side of the cardboard conveying device 6, and the cardboard bending mechanism 9 is used to bend both sides of the long sides of the conveyed cardboard 5; The paperboard bending mechanism 9 includes a transport shaft 903 and a transport chain 901. A sprocket is provided on the outer wall of the transport shaft 903. The sprocket drives the transport chain 901 to move. The transport chain 901 is arranged above the tail end of the conveyor chain 602. A plurality of transport racks 902 are also arranged on the transport chain 901. The distance between the transport racks 902 corresponds to the length of the paperboard. The paperboard is driven to move by the action of the transport chain 901 and the transport rack 902. Bending guard plates 904 are provided on opposite sides of the transmission chain 901 . The tail ends of the bending guard plates 904 are close to the transmission chain 901 , and bending plates for bending the paperboard 5 are provided at the ends thereof.

[0031] When the conveyor chain 602 drives the cardboard 5 to move to the front end of the transmission chain 901, the cardboard 5 will continue to move forward through the action of the transmission frame 902, and in the process of moving forward, the side edge of the long side of the cardboard 5 will contact the bending plate, which is set in an inclined manner in the transportation direction of the cardboard 5, that is, there is a height difference between the rear end of the bending plate and the transmission chain 901, and the two sides of the transported cardboard 5 are bent by squeezing the height difference. In this way, the bending parts of multiple cardboards 5 are fixed, which is convenient for subsequent packaging and makes the integrity of multiple packages consistent.

[0032] The end of the cardboard bending mechanism 9 is above the noodle conveying device 8, and the cardboard bending mechanism 9 conveys the bent cardboard 5 to the noodles above the noodle conveying device 8. The cardboard 5 will cover the noodles on the noodle conveying device 8, which is convenient for the subsequent packaging process.

[0033] In this embodiment, the cardboard 5 is bent during transportation and placed on the corresponding hanging surface that needs to be packaged, so as to facilitate the subsequent packaging process.
