DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please refer to Figure 1-5, Embodiment 1 of the present invention provides a conveying device for stamping and loading a face cover 4, the conveying device includes a feed conveyor belt 1 and a material limiting conveying structure 2, the feed conveyor belt 1 is connected to one side of the material limiting conveying structure 2, the feed conveyor belt 1 conveys the face cover 4 to the material limiting conveying structure 2, wherein the material limiting conveying structure 2 includes an annular feeding platform 21 and a plurality of groups of material shifting and limiting mechanisms 22, the plurality of groups of material shifting and limiting mechanisms 22 are spaced apart from each other and parallel to the transverse direction of the annular feeding platform 21, each group of material shifting and limiting mechanisms 22 includes a material shifting rod 221, a hinged fixed shaft 222, and an opening and closing tension spring 225 for facilitating the opening and closing of the material shifting rod 221, the material shifting rod 221 is parallel to the transverse direction of the annular feeding platform 21, and the hinged fixed shaft 222 is installed on the annular feeding platform 2 1, one end of the material removing rod 221 is connected to the hinged fixed shaft 222, one end of the opening and closing tension spring 225 is connected to the upper part of the other end of the material removing rod 221, and the other end of the opening and closing tension spring 225 is fixed above the outer edge of the annular feeding platform 21. The distance between the other end of the material removing rod 221 and the outer side of the annular feeding platform 21 forms a single cover conveying channel 224. In specific implementation, the feed conveyor belt 1 is connected to the feed end of the annular feeding platform 21 on one side of the material limiting conveying structure 2. The distance between the other end of the material removing rod 221 of each group of material removing limiting mechanisms 22 and the outer side of the annular feeding platform 21 is the distance of a surface cover 4, and the single cover conveying channel 224 is formed by the distance between the other end of the material removing rod 221 and the outer side of the annular feeding platform 21. When the multi-channel cover 4 conveyed on the annular feeding table 21 is delivered to the material-pulling rod 221 of the material-pulling limiting mechanism 22, the material-pulling rod 221 is pushed to open under the conveying thrust of the cover 4 and the elastic tension of the opening and closing tension spring 225. At this time, the opening and closing tension spring 225 above the material-pulling rod 221 is in a stretched state, and the multi-channel cover 4 is converted into a single-channel cover 4 through the cover-limiting conveying single channel 224, realizing the limited conveying of the cover channel. After the cover 4 passes through the cover-limiting conveying single channel 224, the opening and closing tension spring 225 above the material-pulling rod 221 needs to restore its deformation. Under the action of the opening and closing tension spring 225 above the material-pulling rod 221, the material-pulling rod 221 will return to The original position (i.e. the distance between the material shifting rod 221 and the outer edge of the annular feeding table 21 by one face cover 4) is achieved by cooperating with the material shifting rod 221 of the material shifting limiting mechanism 22 and the opening and closing tension spring 225, so that the multi-channel face covers 4 conveyed by the annular feeding table 21 can be conveyed with single-channel limited cover, thereby preventing the multi-channel face covers 4 from being stuck, and also preventing the multi-channel face covers 4 on the annular feeding table 21 from piling up during the conveying process, thereby avoiding confusion or jamming of the multi-channel face covers 4 during the conveying process, achieving uniform and orderly conveying of the face covers 4, preventing damage to the face covers 4, and protecting the face covers 4. At the same time, it also ensures the continuous supply and loading of the face covers 4 of the punching machine 6.

[0026] The conveying device of the present invention includes a cover-blocking and protective mechanism 24, which is fixed to the side of the annular feeding platform 21 and is located at the next station of each group of material-dispensing and limiting mechanisms 22, that is, the cover-blocking and protective mechanism 24 is located at the next station of the single cover-limiting and conveying channel 224. The cover-blocking and protective mechanism 24 includes a cover-blocking and protective cylinder 241 and a protective plate 242. The cover-blocking and protective cylinder 241 is fixed to the side of the annular feeding platform 21, and the piston rod of the cover-blocking and protective cylinder 241 is connected to the protective plate 242. The protective plate 242 is driven to move by the cover-blocking and protective cylinder 241, which limits the surface cover 4, preventing the surface cover 4 conveyed on the annular feeding platform 21 from colliding with the edge of the side of the annular feeding platform 21, and plays a role in limiting and protecting the conveyance of the surface cover 4, while also ensuring the stability of the surface cover 4 during the conveyance process.

[0027] The conveying device of the present invention includes a plurality of cover discharging and loading conveyor belts 3, which are distributed at intervals on the other side of the material limiting conveying structure 2, and one end of each cover discharging and loading conveyor belt 3 is connected to the other side of the annular feeding platform 21. In specific implementation, each cover discharging and loading conveyor belt 3 is connected to the other side of the annular feeding platform 21, and a cover discharging conveying channel 25 is provided on the other side of the annular feeding platform 21. The cover discharging and loading conveyor channel 25 is located at the next workstation of the cover blocking protection mechanism 24, and the cover discharging and loading conveyor channel 25 is composed of two arc-shaped guide rods 251, which are distributed in parallel and at intervals. The distance between the two arc-shaped guide rods 251 forms the cover discharging and loading conveyor channel 25, so that the face cover 4 passing through the cover limiting conveying single channel 224 is transported to the cover discharging and loading conveyor channel 25, and then transported to the cover discharging and loading conveyor belt 3 by the cover discharging and loading conveyor channel 25, and the other end provided between the cover discharging and loading conveyor belts 3 is connected with a punching machine 6. The face covers 4 conveyed by the material limiting conveying structure 2 are conveyed to the punching machine 6 via the cover discharge and loading conveyor belt 3, so that the face covers 4 can be loaded in an orderly manner. The feeding conveyor belt 1 is connected to the cover discharge end of the unloading machine detection frame 5.

[0028] In a specific implementation of the embodiment of the present utility model, each set of the material-dipping limiting mechanism 22 includes a plurality of material-dipping fixing frames 23, which are fixed above the annular feed platform 21 at intervals. The position of each material-dipping fixing frame 23 is distributed along the transverse direction of the annular feed platform 21 and is located above the annular feed platform 21.

The material-dipping fixing frame 23 is designed in a door-shaped structure, which facilitates the installation and fixation of the material-dipping fixing frame 23.

[0029] The utility model is provided with a pull rod 2211 fixed above the other end of the material removing rod 221, and one end of the opening and closing tension spring 225 is sleeved on the pull rod 2211 above the other end of the material removing rod 221 to realize the connection between one end of the opening and closing tension spring 225 and the other end of the material removing rod 221. In specific implementation, a connecting column corresponding to the position of the opening and closing tension spring 225 is fixed above the outer edge of the annular feeding platform 21, and the other end of the opening and closing tension spring 225 is sleeved on the connecting column at the outer edge of the annular feeding platform 21. The opening and closing tension spring 225 set in the utility model has the following two main functions: on the one hand, when the face cover 4 has not yet been conveyed to the position of the material removing rod 221, the other end of the material removing rod 221 can be kept close to the outer side of the annular feeding platform 21 and the material removing rod 221 is at a distance of one face cover 4 from the outer side of the annular feeding platform 21; on the other hand, when the face cover 4 is conveyed to the position of the material removing rod 221, the other end of the material removing rod 221 is convenient to open under the pushing action of the face cover 4 and the elastic force of the opening and closing tension spring 225, so that the face cover 4 can smoothly pass through the limited conveying single channel, thereby ensuring the conveying of the single-channel face cover 4.

[0030] In the embodiment of the present invention, each set of the material-dispensing and limiting mechanisms 22 includes a limiting guide plate 223, which is arranged along the conveying direction of the cover 4 of the single cover-limiting and conveying channel 224. The limiting guide plate 223 is mounted at the other end of the material-dispensing rod 221 and is located on the annular feed platform 21. After being limited by the material-dispensing rod 221, the multi-channel cover 4 conveyed on the annular feed platform 21 will be conveyed out of the single cover-limiting and conveying channel 224. The provision of the limiting guide plate 223 can play a role in guiding the conveying of the cover, making it easier for the cover 4 to be conveyed in an orderly manner along the conveying direction of the single cover-limiting and conveying channel 224.

[0031] The material limiting and conveying structure 2 of the present invention includes an annular material guiding rod 211 . The annular material guiding rod 211 is distributed on the outer periphery of a plurality of groups of material shifting and limiting mechanisms 22 and is fixed to the inner edge of the annular material feeding platform 21 .

[0032] The working process of the conveying device of the present invention for feeding the punching machine 6 with materials and caps is as follows:

[0033] First, the cover 4 is inspected by the unloading machine inspection frame 5 and then transported to the annular feeding platform 21 of the material limiting conveying structure 2 through the feeding conveyor belt 1;

[0034] Next, the face covers 4 conveyed on the annular feeding platform 21 will form a multi-channel face cover 4 conveyance after passing through the arc-shaped bend of the annular feeding platform. When the multi-channel face covers 4 are conveyed to the material-moving rod 221 of the material-moving limiting mechanism 22, the material-moving rod 221 will push the material-moving rod 221 to open under the thrust of the face covers 4 conveyed forward and the elastic force of the opening and closing tension spring 225. The multi-channel face covers 4 are transformed into a single-channel conveyance through the single-channel cover-limiting conveyance 224, thereby realizing the cover-limiting conveyance of the multi-channel face covers 4 into the single-channel face covers 4;

[0035] Then, the cover 4 is conveyed to the cover discharge and loading conveyor belt 3 along the cover conveying direction of the cover limiting conveying single channel 224;

[0036] Finally, the cover discharging and loading conveyor belt 3 conveys the cover 4 to the punching machine 6.

[0037] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
