Technical Field

[0001] The utility model relates to the technical field of copper powder grinding, in particular to a copper powder grinding anti-blocking discharge pipe. Background Art

[0002] A grinder is a commonly used device for grinding particles or block objects, and copper powder processing also requires a grinder for grinding. The ground copper powder is discharged from the discharge pipe.

[0003] The existing copper powder discharge pipe does not have an anti-blocking function. Copper powder is easily blocked in the pipe and needs to be knocked from outside the pipe or unblocked from inside the pipe. The grinder needs to be stopped when unblocking the pipe, which not only easily delays the progress of copper powder grinding, but also increases the workload of unblocking the copper powder discharge pipe. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a copper powder grinding anti-blocking discharge pipe, which solves the problem that the existing copper powder discharge pipe has no anti-blocking ability and is difficult to automatically dredge the pipe by utilizing the gradually increasing weight of the copper powder blocked in the pipe.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a copper powder grinding anti-blocking discharge pipe, comprising an intermediate pipe, inner pipes are installed at both ends of the intermediate pipe, a dredging groove is opened on the inner wall of the intermediate pipe, and an anti-blocking component is installed inside the dredging groove to dredge the blocked copper powder from top to bottom after the weight of the copper powder in the intermediate pipe increases;

[0006] The anti-blocking component includes a lifting ring slidably connected to the inner wall of the dredging groove, a plurality of longitudinal plates are fixedly connected to the top of the lifting ring, an arc-shaped plate extending to the outside of the dredging groove is provided on the top of the longitudinal plate, a tilting rod is fixedly connected to the top of the arc-shaped plate, and a metal spring is fixedly connected between the bottom of the lifting ring and the inner wall of the dredging groove.

[0007] Preferably, a cone is installed at one end of the bottom of the tilting rod, and the tilting rod and the cone are both made of wear-resistant plastic material.

[0008] Preferably, one side of the metal spring sheet is fixedly connected to a lever, and the metal spring sheet is squeezed and bent to push the lever to extend to the outside of the dredging groove.

[0009] Preferably, the inner tube movably extends into the interior of the middle tube, and a plurality of bolts movably extending into the interior of the middle tube are provided on the outer side of the middle tube.

[0010] Preferably, both sides of the middle tube are fixedly connected with elastic paddles, a side of the elastic paddle close to the middle tube is fixedly connected with an impact block, and a side of the elastic paddle away from the impact block is fixedly connected with a protrusion.

[0011] Preferably, an arc groove matching the curvature of the middle tube is formed on one side of the protrusion, a plurality of elastic rods are fixedly connected to one side of the protrusion, and a weight ball is fixedly connected to one end of the elastic rod away from the protrusion.

[0012] Compared with the prior art, the utility model provides a copper powder grinding anti-blocking discharge pipe, which has the following beneficial effects:

[0013] 1. The anti-blocking component is set up to make the copper powder discharge pipe have the ability to prevent blocking. It can use the gradually increasing weight of the copper powder blocked in the pipe to automatically dredge the pipe, reducing the workload of the staff to dredge the pipe.

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Embodiment 1

[0025] Figure 1-Figure 3 As one embodiment of the utility model, a copper powder grinding anti-blocking discharge pipe comprises an intermediate tube 1, inner tubes 2 are installed at both ends of the intermediate tube 1, a dredging groove is opened on the inner wall of the intermediate tube 1, and an anti-blocking component 3 is installed inside the dredging groove for dredging the blocked copper powder from top to bottom after the weight of the copper powder in the intermediate tube 1 increases. The ground copper powder is discharged from the intermediate tube 1 and the inner tube 2. When the copper powder is blocked in the intermediate tube 1 and the inner tube 2 at the top thereof, the anti-blocking component 3 dredges the copper powder blocked in the pipeline to ensure that the copper powder can pass through the intermediate tube 1 and the inner tube 2 smoothly.

[0026] The anti-blocking component 3 includes a lifting ring 31 which is slidably connected to the inner wall of the dredging groove, a plurality of longitudinal plates 32 are fixedly connected to the top of the lifting ring 31, a curved plate 33 extending to the outside of the dredging groove is provided on the top of the longitudinal plate 32, a tilting rod 34 is fixedly connected to the top of the curved plate 33, and a metal spring 35 is fixedly connected between the bottom of the lifting ring 31 and the inner wall of the dredging groove. When in use, the ground copper powder passes through the inner tube 2, the middle tube 1 and the inner tube 2 in turn and is discharged. When the copper powder is blocked in the inner tube 2 at the top of the middle tube 1, the copper powder gradually accumulates above the middle tube 1, and the blocked copper powder squeezes the curved plate 33 downward. As the blocked copper powder gradually increases, the weight of the copper powder squeezing the curved plate 33 downward also gradually increases, and the curved plate 3 After being squeezed downward, the lifting ring 31 is pushed down, and the lifting ring 31 squeezes and bends the metal spring piece 35. At this time, the longitudinal plate 32, the arc plate 33 and the tilting rod 34 all fall down, and the copper powder around the empty gap where the tilting rod 34 was originally located collapses to that place. The copper powder originally squeezed into a pile begins to loosen and fall downward, and the weight of the copper powder squeezing the arc plate 33 is reduced. The metal spring piece 35 pushes the lifting ring 31 and the arc plate 33 to rise until the blocked copper powder is completely discharged. At this time, the metal spring piece 35 pushes the lifting ring 31 and the arc plate 33 to rise to the starting point, so that the copper powder discharge pipe has the ability to prevent blocking, and can automatically dredge the pipe by using the gradually increasing weight of the copper powder blocked in the pipe, reducing the workload of the staff in dredging the pipe.

[0027] A cone 4 is installed at one end of the bottom of the tilting rod 34. The tilting rod 34 and the cone 4 are both made of wear-resistant plastic. A lever 5 is fixedly connected to one side of the metal spring 35. After the metal spring 35 is squeezed and bent, it pushes the lever 5 to extend to the outside of the dredging groove. When the copper powder is blocked, the copper powder pushes the arc plate 33 and the lifting ring 31 to descend and squeeze and bend the metal spring 35. After the tilting rod 34 descends with the arc plate 33, a vacant position is generated inside the blocked copper powder. The cone 4 descends with the tilting rod 34, which can make the vacant position inside the copper powder larger, so that the copper powder can collapse and flow faster. At the same time, the bent metal spring 35 pushes the lever 5 to move obliquely upward, which can contact and move the bottom of the blocked copper powder, thereby speeding up the dredging of the copper powder.

[0028] The inner tube 2 is movably extended to the inside of the middle tube 1, and the outer side of the middle tube 1 is provided with a plurality of bolts 6 movably extended to the inside thereof. When in use, the two inner tubes 2 are respectively inserted into the inside of the middle tube 1 from both ends of the middle tube 1, and then the bolts 6 are rotated until the bolts 6 squeeze the inner tube 2 and fix the inner tube 2 on the middle tube 1, which can facilitate the installation and disassembly of the inner tube 2 and the middle tube 1.

[0029] Embodiment 2

[0030] Reference Figure 1-Figure 4 On the basis of the first embodiment, elastic paddles 7 are fixedly connected to both sides of the middle tube 1, and a collision block 8 is fixedly connected to the side of the elastic paddle 7 close to the middle tube 1, and a protrusion 9 is fixedly connected to the side of the elastic paddle 7 away from the collision block 8. When the copper powder in the middle tube 1 and the inner tube 2 is blocked, the staff holds the protrusion 9, then pulls the elastic paddle 7 to bend in the direction away from the middle tube 1, and finally releases the protrusion 9. The elastic paddle 7 pushes the collision block 8 to hit the middle tube 1 under its own elastic action, and can actively vibrate the pipeline by hitting the pipeline, and then use the vibration to make the blocked copper powder fall off and then dredge it.

[0031] An arc groove matching the curvature of the middle tube 1 is provided on one side of the protrusion 9. A plurality of elastic rods 10 are fixedly connected to one side of the protrusion 9. A counterweight ball 11 is fixedly connected to one end of the elastic rod 10 away from the protrusion 9. When the elastic paddle 7 drives the impact block 8 to collide with the middle tube 1, the elastic rod 10 drives the counterweight ball 11 to shake continuously after the collision, thereby increasing the vibration amplitude and time of the protrusion 9 and enhancing the effect of using vibration to clear the copper powder blocked in the pipeline.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
