DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3 In the present embodiment, a shell breaking device for nut processing comprises an operating table 1, on the table top of the operating table 1, a conveying device 2 and a movable plate 15 located below the tail end of the conveying device 2 are installed, the conveying portion of the conveying device 2 is composed of a plurality of arc-shaped plates, a propulsion block 12 located at the center line and a blanking assembly are fixed on the plate surface of the movable plate 15, a sleeve hole 13 is provided on the left side of the propulsion block 12, an extrusion column 14 is fixed on the inner side of the sleeve hole 13, and the extrusion column 14 is T-shaped, a pushing assembly is installed on the left side of the conveying device 2, an extrusion cylinder 9 and a sleeve 10 fixed to the ejection end of the extrusion cylinder 9 are installed on one side of the lifting portion of the pushing assembly, and side notches are provided on both sides of the sleeve 10.

[0017] In the above structure, the nuts are carried by the arc plate in the conveying device and conveyed to the tail end, and the nuts in the arc plate are pushed into the sleeve by the pushing component and conveyed to be aligned with the extrusion column. The extrusion cylinder pushes out to drive the sleeve forward, and the sleeve can extend into the sleeve hole. With the help of the side notch, the extrusion column can avoid affecting the advancement of the sleeve. At the same time, the sleeve hole can also limit the sleeve to avoid the sleeve being stretched and damaged during the extrusion process, until the nut shelling is completed under the action of the sleeve and the extrusion column. After the shelling is completed, during the retreat of the sleeve, the unloading component guides the internal nuts through the side notch to complete the unloading operation, thereby realizing automatic and continuous shelling and improving production efficiency.

[0018] The pushing assembly includes a pushing assembly and a feeding assembly. The pushing assembly includes a linear module 3 installed at the tail end of the conveying device 2. A pushing block 4 is fixed to the moving end of the linear module 3. One end of the pushing block 4 is cylindrical and fits the inner side of the arc plate. When the conveying device conveys the nuts to the tail end, where the arc plate is opposite to the pushing block, the linear module drives the pushing block to move, and the pushing block pushes the nuts therein. The nuts are pushed to the left by the nuts pushing the nuts, thereby achieving the function of pushing the materials.

[0019] In addition, the feeding assembly includes a side plate 5 fixed to the left side of the conveying device 2, a through pipe 6 is fixed on the side of the side plate 5 opposite to the cylindrical end of the push block 4, and a push-down cylinder 7 is installed on the top, a push plate 8 sliding with the side plate 5 is fixed to the ejection end of the push-down cylinder 7, a material guide channel is formed between the push plate 8 and the side plate 5, and the extrusion cylinder 9 is installed on the push plate 8. When the above-mentioned push assembly pushes nuts, the nuts will extend into the sleeve through the through pipe, and then the push-down cylinder drives the push plate to move downward, so that the sleeve moves in the material guide channel until the sleeve moves to align with the extrusion column, completing the feeding operation.

[0020] like Figure 3 A screw device 11 is installed on the top of the operating table 1. The outer side of the screw of the screw device 11 is threadedly connected to the moving plate 15, and the moving plate 15 is slidably connected to the operating table 1. The screw device can drive the moving plate to move, thereby driving the advancement of the fast movement, so that the distance between the squeezing column and the sleeve can be adjusted, so that the squeezing force of the sleeve on the nut in cooperation with the squeezing column when advancing can be controlled, and when the screw device drives the squeezing column to continue to advance, the squeezing force can be continuously increased, so the squeezing force can be adjusted according to demand.

[0021] In addition, the unloading assembly includes a side plate 16 fixed on the surface of the moving plate 15, and a clamping cylinder 17 is installed on the side of the side plate 16 close to the sleeve 10. The clamping end of the clamping cylinder 17 is respectively fixed with a clamping block 18 and a concave block 19, and the clamping block 18 is located on the concave surface of the concave block 19. Side notches are opened on both sides of the sleeve 10. When the sleeve and the extrusion column squeeze the nut to break the shell, the clamping cylinder opens, driving the clamping block and the concave block to pass through the side notch to clamp the nut inside, and then when the sleeve retreats, the nut can be removed from the sleeve to complete the unloading operation.

[0022] The working principle of the above embodiment is:

[0023] First, according to the needs, the movable plate is driven to move through the screw device, thereby driving the push block to move, adjusting the extrusion column to a suitable position, controlling the extrusion force, and the conveying device conveys the nuts to the tail end to align with the push block and the through tube, and the sleeve is aligned with the through tube, and then the push block is driven to move by the linear module, the nut is pushed to the through tube and moved into the sleeve, the push-down cylinder drives the push plate to move downward until the sleeve moves down to align with the extrusion column, the extrusion cylinder drives the sleeve to advance, the sleeve extends into the sleeve hole, and the extrusion column extends into the sleeve to complete the extrusion and shelling of the nut. After the shelling is completed, the sleeve is in the process of retreating, and the clamping cylinder drives the clamping block and the concave block to clamp the nut until the sleeve is completely retreated, and the nut can be moved out to complete the unloading operation, and then the above operation is repeated to realize the automated continuous shelling operation, thereby effectively improving the production efficiency.
