[0039] The utility model provides a connection structure in a blanking device, which includes a positioning guide rail and a connection member; the connection member includes a base plate, and a first roller and a second roller mounted on the base plate; the base plate is used to connect with the blanking unit; the track of the positioning guide rail is located between the first roller and the second roller, and the first roller and the second roller are rollingly connected on opposite sides of the track. In the connection structure in the blanking device, the connection member is rollingly connected to opposite sides of the positioning guide rail through the first roller and the second roller, so that it can bear torque in more directions, making the connection between the connection member and the positioning guide rail more stable and reliable. During long-term use, the connection member is not prone to deflection; and the connection member is used to connect with the blanking unit, so as to better avoid the deflection of the blanking unit and better ensure the normal blanking or blocking of the blanking unit.

[0040] Please refer to Figures 1 to 5 This embodiment provides a connection structure 100 in a blanking device, which is mainly used to solve the problem in the prior art that the components connected to the positioning guide rail are unstable in force and prone to deflection, thereby affecting normal blanking or blocking.

[0041] The connection structure 100 in the blanking device includes a positioning guide rail 10 and a connecting member 20. The connecting member 20 includes a base plate 21, and a first roller 23 and a second roller 24 mounted on the base plate 21. The base plate 21 is used to connect to the blanking unit. The track 11 of the positioning guide rail 10 is located between the first roller 23 and the second roller 24, and the first roller 23 and the second roller 24 are rollingly connected on opposite sides of the track 11. The positioning guide rail 10 can be formed by splicing multiple sections of the track 11 in sequence. In other words, the connecting member 20 is clamped on the track 11 through the first roller 23 and the second roller 24, so that it can be connected to receive force from at least two sides of the track 11, making the force more stable.

[0042] It is understandable that in the unloading device in the prior art, the unloading unit is usually connected to one side of the positioning guide rail through a roller, so that the force is biased to one side, resulting in unstable force.

[0043] In the connection structure 100 in the blanking device provided in this embodiment, the connection member 20 can be connected to the blanking unit, and the connection member 20 is connected to the two opposite sides of the positioning guide rail 10 through the first roller 23 and the second roller 24, so that the force is more balanced and can bear torque in more directions, making the connection between the connection member 20 and the positioning guide rail 10 more stable and reliable. The connection member 20 can be connected to the blanking unit, so as to better ensure the force stability between the blanking unit and the positioning guide rail 10. During long-term use, the blanking unit is not prone to deflection, so as to better ensure the normal blanking and blocking of the blanking unit. At the same time, the setting of the bottom plate 21 also makes the installation of the blanking unit more convenient, and during installation, the connection member 20 can be installed on the positioning guide rail 10 first, and then the blanking unit can be installed, which also reduces the difficulty of installing the connection member 20.

There are two second rollers 24, and the two second rollers 24 are arranged side by side along the extension direction of the positioning guide rail 10, that is, the two second rollers 24 are connected to the track 11 in a rolling manner one after the other. Through this structure, the balance of the force on the connecting member 20 along the extension direction of the positioning guide rail 10 can be better guaranteed, so that the connecting member 20 is not easily deflected along the extension direction of the positioning guide rail 10. That is to say, in this embodiment, the connecting member 20 is connected to the positioning guide rail 10 in a rolling manner through four rollers, so that it can bear torques in more directions, making the connection more stable and reliable.

[0046] Preferably, in one embodiment, the two first rollers 23 and the two second rollers 24 are arranged opposite each other, that is, one second roller 24 is arranged on the opposite side of one first roller 23, and another second roller 24 is arranged on the opposite side of another first roller 23. The four rollers are distributed in a rectangular structure as a whole, so as to better ensure the balance of force.

[0047] Preferably, in one embodiment, the first roller 23 is rollingly connected to the inner side 12 of the positioning guide rail 10, and the second roller 24 is rollingly connected to the outer side 13 of the positioning guide rail 10. That is, in this embodiment, the first roller 23 and the second roller 24 are connected to opposite sides of the positioning guide rail 10 in the horizontal direction, which can better utilize the horizontal space and avoid interference with other components in the equipment.

The blanking unit 200 includes a fixed part and a movable part that can be relatively raised and lowered. Specifically, in one embodiment, a material cavity having a feed port and a discharge port is provided in the fixed part and / or the movable part. By raising and lowering the movable part relative to the fixed part, the material cavity can be blocked or opened, so that the material is temporarily stored in the material cavity or the material flows out from the discharge port, thereby achieving blocking or blanking. The movable part is provided on the downward pressure guide rail 300, and there is a height difference in some areas of the downward pressure guide rail 300, so that when the movable part moves along the downward pressure guide rail 300, the downward pressure guide rail 300 can drive the movable part to rise or fall, thereby controlling the relative lifting between the fixed part and the movable part, thereby achieving blocking or blanking of the blanking unit 200. The fixed part is connected to the bottom plate 21.

[0054] Preferably, in one embodiment, the movable part is mounted on the downward pressure guide rail 300 through a cam follower, and is supported on the guide rail through the cam follower. During the movement of the movable part, the cam follower can roll on the guide rail, thereby avoiding wear between the movable part and the guide rail, and can better improve the service life.
