The detailed connection means is a known technology in the art, and the working principle and process are mainly introduced below, and the electrical control is not described.

[0043] Example 1: according to the description Figures 1-11It can be known that the application discloses a conveying and sorting machine for bearing production, which comprises a feeding hopper 1, a main machine shell 2 and two pairs of supporting legs 7, the main machine shell 2 is a shell with a rectangular cavity structure, the feeding hopper 1 is installed on one side of the main machine shell 2 and communicates with the inside of the main machine shell 2, the bottom surface of the main machine shell 2 is provided with the two pairs of supporting legs 7, the inside of the main machine shell 2 is provided with a discharging and sorting mechanism 3, a first magnetic floatation mechanism 4 is arranged in connection with the discharging and sorting mechanism 3, and a second separation mechanism 5 is arranged in connection with the first magnetic floatation mechanism 4, in the specific implementation process, the side wall of the main machine shell 2 is connected to the adjacent wall through a plurality of screws, a plurality of heat dissipation grooves 8 are formed in the outer side wall of the main machine shell 2, the heat dissipation grooves 8 facilitate disassembly and maintenance, increase the heat dissipation effect and avoid overheating of the internal components, the feeding hopper 1 is installed on one side of the main machine shell 2 and is used for adding materials to the discharging and sorting mechanism 3 in the main machine shell 2, so that the materials fall into the first magnetic floatation mechanism 4 along the discharging and sorting mechanism 3, the first magnetic floatation mechanism 4 sorts the steel bearing ring pieces by using the principle of magnetic adsorption, the bearing inner ring is screened out by using the magnetic action, and the magnetic outer ring is conveyed to the second separation mechanism 5 to be sorted for the second time, so as to complete the sorting of the bearing inner and outer rings.

[0044] According to the description attached Figures 1-11 It can be known that the first magnetic floatation mechanism 4 comprises a conveying slope channel 41, a roller shaft conveyor 42, a pair of transmission roller shafts 43, a pair of transmission roller belts 44, a plurality of conveying plates 45, a plurality of electromagnets 46 and a first discharging port 47, and the connection relationship and position relationship are as follows.

[0045] The top end of the conveying slope channel 41 is connected to the bottom end of the discharging and sorting mechanism 3, the bottom end of the conveying slope channel 41 is connected with the roller shaft conveyor 42, the two ends of the main machine shell 2 are respectively provided with a pair of symmetrical transmission roller shafts 43, a pair of symmetrical transmission roller belts 44 are sleeved on the transmission roller shafts 43, a plurality of steel conveying plates 45 are sleeved on the transmission roller belts 44, a plurality of electromagnets 46 are arranged on the inner sides of the conveying plates 45, a first discharging port 47 is formed in one side of the main machine shell 2, a separation and discharging assembly 48 is arranged on the first discharging port 47, the ends of the transmission roller shafts 43 penetrate through the side wall of the main machine shell 2, a pair of transmission gears 9 are sleeved on the ends of the transmission roller shafts 43, a transmission chain 10 is sleeved on the transmission gears 9, and the driving end of a transmission motor 11 is connected with the end of one of the transmission roller shafts 43.

[0046] In the specific implementation process, the width of the conveying slope channel 41 matches the gap width of the bottom end of the blanking and straightening mechanism 3, and is slightly larger than the width of the bearing ring side. When the conveying slope channel 41 sends the bearing ring to the roller conveyor 42, a pair of transmission rollers 43 are connected through a pair of transmission roller belts 44, and form a complete chain conveyor with a plurality of conveying plates 45. Each conveying plate 45 is provided with an electromagnet 46. The electromagnet 46 generates magnetism through energization control, thereby attracting the bearing ring to adhere to the conveying plate 45. Due to the action of gravity, the heavier bearing outer ring cannot be attracted, and the lighter bearing inner ring is attracted to the conveying plate 45. The conveying plate 45 is made of steel structure, and the steel conveying plate 45 is driven by the transmission roller 43 to move forward, thereby conveying the attracted bearing inner ring to the side of the first blanking port 47. The bearing inner ring is stripped off by the separating blanking assembly 48 to complete one sorting. The movement of the pair of transmission rollers 43 is driven by the transmission motor 11 to rotate one transmission roller 43. The transmission gear 9 and the transmission chain 10 are engaged to transmit torque to drive the other transmission roller 43 to rotate synchronously.

[0047] According to the description attached Figures 1-11 It can be seen that the above blanking and straightening mechanism 3 comprises: a feeding port, a pair of sliding plates 31, a pair of sliding ways, an adjusting hopper 32, two pairs of fixed plates 33, a plurality of pairs of springs 35 and a pair of vibration motors 36. The connection relationship and positional relationship are as follows:

[0048] A feeding port is provided at the top of the conveying slope channel 41. A pair of parallel sliding plates 31 is symmetrically provided on the feeding port. The bottom end of the adjusting hopper 32 is provided with a pair of sliding ways matched with the pair of sliding plates 31. An upper feeding port is provided in the side wall of the main machine shell 2 and connected with the upper feeding hopper 1. The inner side of the upper feeding port is provided with the same structure as the feeding port and is communicated with one side of the top end of the adjusting hopper 32. The adjusting hopper 32 is a hollow shell. Two pairs of fixed plates 33 are symmetrically provided on the two sides of the adjusting hopper 32. A plurality of pairs of springs 35 are provided on the two pairs of fixed plates 33 and connected to the two sides of the adjusting hopper 32.

The two ends of the adjusting hopper 32 are respectively connected with the upper feeding port and the feeding port.

[0049] In the specific implementation process, the material enters the adjusting hopper 32 through the upper feeding port. The adjusting hopper 32 is vibrated and slightly horizontally moved in the horizontal direction by controlling the operation of the pair of vibration motors 36. The horizontal movement effect is limited by the plurality of pairs of springs 35 on the fixed plates 33 to avoid excessive shaking of the adjusting hopper 32 causing material leakage. The sliding design of the feeding end and the discharging end of the adjusting hopper 32 with the same structure makes the adjusting hopper 32 more stable when shaking, avoiding the adjusting hopper 32 from being out of control of the machine body, so that the material will not block the feeding port of the lower conveying slope channel 41 under the action of vibration and shaking.
