Detailed Description

The following describes in detail specific embodiments of the present invention. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, the use of the terms of orientation such as "upper and lower" in the case where no description is made to the contrary generally means the orientation in the assembled and used state. "inner and outer" refer to the inner and outer contours of the respective component itself.

In the present invention, a feeding device is provided, as shown in fig. 1, the feeding device includes a bin, a feeding plane 17, and a conveying mechanism capable of conveying material in the bin to the feeding plane 17.

Therefore, the conveying mechanism can convey the material in the bin to the material plane 17, and automatic feeding can be realized by combining the parts on the punching machine, so that the working efficiency of punching is improved.

The storage bin and the feeding plane 17 can be arranged on the same plane or different planes. In an embodiment of the present invention, the storage bin and the feeding plane 17 are disposed on different horizontal planes, the feeding plane 17 is located above the storage bin, and the feeding plane 17 is disposed as an inclined plane, and an included angle between the inclined plane and the horizontal plane is preferably set to be 15 ° to 30 °, so that the material on the feeding plane 17 can naturally slide to the edge of the feeding plane 17 (a position convenient for the punching machine to take the material) under the action of gravity, so as to facilitate the punching machine to take the material. As shown in fig. 4, the storage bin is a box body which is enclosed by a bottom plate 12 and two limit baffles 14 and is provided with an opening at the upper part. The bottom plate 12 is arranged to be an inclined plane, and an included angle between the inclined plane and the horizontal plane is 15-30 degrees. In this way, the material placed on the base plate 12 will naturally slide down to the transport mechanism due to the effect of gravity.

It should be noted that, as shown in fig. 1, the "material loading plane 17 is set as an inclined plane" means that the lower part of the inclined plane extends to be close to the chain (i.e., "upper outside and lower inside" as shown in fig. 1); the term "the bottom plate 12 is configured as a slope" means that the lower part of the slope extends to the edge of the loading device (i.e., "the inner part is higher than the outer part as shown in fig. 1).

The conveying mechanism comprises a chain wheel 16, a chain meshed with the chain wheel 16, a driving motor used for driving the chain wheel 16 and a hook part 15 arranged on the chain, wherein the hook part 15 moves along with the movement of the chain. The chain perpendicular to horizontal plane sets up and extends to bottom plate 12 places material of bottom plate 12 department receives the action of gravity can naturally slide to chain department, behind the drive sprocket 16, colludes portion 15 on the chain and can catch on material to transport material on the bottom plate 12 to material plane.

The silo includes a bottom plate 12, limit plates 14 located at both sides of the bottom plate 12, and a driving assembly for driving the limit plates 14 away from and close to each other. Two specific embodiments of drive assemblies are provided below:

the first embodiment is as follows: as shown in fig. 1, the driving assembly includes a sliding rail 134, a linear bearing 133 disposed at the bottom of the position limiting plate 14, a lead screw 132 disposed at the bottom of the bottom plate 12, and a hand wheel 131 connected to one end of the lead screw 132; the linear bearing 133 is slidably connected to the sliding rail 134, and the limit plate 14 is connected to the lead screw 132. Turning the handwheel 131 drives the lead screw 132 to turn, thereby driving the two stopper plates 14 to move closer to or away from each other.

The second embodiment is as follows: as shown in fig. 2, the driving assembly includes a sliding rail 134 and a motor 135 disposed at the bottom of the position limiting plate 14, and the motor 135 can drive the position limiting plate 14 to move along the sliding rail 134. The motor 135 may be a linear motor.

In order to detect the quantity of the material on the feeding plane 17 and realize quantitative feeding to the punching machine, the feeding device is further provided with an infrared sensor, and the infrared sensor is used for detecting the quantity of the material on the feeding plane 17.

The working principle of the feeding device is briefly explained by taking a pipeline as an example: firstly, the distance between the limit baffles 14 is adjusted to limit the length of the pipeline placed in the storage bin, and the bottom plate 12 is arranged to be an inclined surface, so that the pipeline can naturally slide to the chain after being placed in the storage bin. The drive sprocket 16 is then activated to drive the chain and thereby transport the pipe from the base plate 12 to the loading level 17. Because the feeding plane 17 is also inclined, the pipeline can slide to the edge of the feeding plane 17 under the action of gravity, so that the punching machine can take materials conveniently.

As shown in fig. 5 and 6, the punching machine includes a material taking support 22, a material taking support bridge 21, and a base 25 disposed below the material taking support, the base 25 is connected to the material taking support 22 through an air cylinder 23, the air cylinder 23 can drive the material taking support 22 to move in the vertical direction, the material taking support bridge 21 is connected to the feeding device and the punching machine, the base 25 is connected to the material taking support bridge 21 through a sliding rail, and the base 25 can slide back and forth on the material taking support bridge 21. When the punching machine takes materials, the material taking support 22 is adjusted through the air cylinder 23, so that the material taking support 22 is lower than the material loading plane 17, the material taking support 22 is moved to the position below the material, then the air cylinder 23 is driven again, the material is borne on the material taking support 22, then the material taking support 22 is driven to slide to the original position along the material taking support bridge 21, and then the material is sent into the punching assembly 24 through the air cylinder 23 to be punched.

In addition, the feeding device further comprises a support frame 11 for supporting the silo, the feeding plane 17 and the conveying mechanism.

As mentioned above, the power source for driving the material taking support 22 can be a motor or a hydraulic cylinder.
