Description

Technical Field

[0001] The utility model relates to the technical field of LED bracket material strip production, in particular to a secondary ejection mechanism with a lever structure. Background Art

[0002] During the production process of LED bracket material strips, the material strips need to be stripped after injection molding. The existing practice is to strip the material on a stripping machine. The material strips need to be conveyed before stripping. The conveying process requires an ejection mechanism to eject the material strips. The push rod on the ejection mechanism pushes out the push plate, and then pushes out the ejector connected to the push plate. After being pushed out, the ejector can push out the limit plate, and then push the material strip out onto the conveying channel. Since the ejector rod is easily damaged by ejecting the material strip once, two ejection mechanisms are generally used in the prior art. However, the use of two ejection mechanisms will not only make the equipment more complicated, but also greatly increase the cost of the equipment. For this reason, we propose a secondary ejection mechanism with a lever structure. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a secondary ejection mechanism of a lever structure, which can effectively solve the problems raised in the above-mentioned background technology after being improved.

[0004] The technical solution of the utility model is:

[0005] A secondary ejection mechanism of a lever structure comprises a push plate assembly, a push rod, a pry rod and an ejector rod assembly;

[0006] The push plate assembly includes a first push plate, a second push plate and a third push plate which are arranged in sequence; the push rod assembly includes a first push rod and a second push rod, the first push rod is fixedly connected to the second push plate, the second push rod is fixedly connected to the first push plate, the second push plate is also rotatably connected to a pry rod, and the third push plate is connected to a push rod at one end away from the first push plate.

[0007] Furthermore, the secondary ejection mechanism also includes a first connecting plate and a second connecting plate, the push plate assembly is arranged between the first connecting plate and the second connecting plate, the push rod is inserted into the first connecting plate, and the other ends of the first ejector rod and the second ejector rod are connected to the second connecting plate and extend to the outside of the second connecting plate.

[0008] Furthermore, an abutment plate is provided between the first connecting plate and the second connecting plate, and one end of the abutment plate abuts against one end of the pry bar.

[0009] Furthermore, the second push plate is rotatably connected to the pry bar via a rotating shaft.

[0010] Furthermore, a return spring is fixedly mounted on the second connecting plate, and the other end of the return spring is fixedly connected to the first push plate.

[0011] The beneficial effects of the utility model are:

[0012] Compared with the prior art, the utility model is provided with a push plate assembly, a pry bar and a push rod assembly. In the process of the push rod being pushed forward, the push plate assembly can be pushed out, and then the first push rod and the second push rod are pushed out a certain distance at the same time, so as to realize one-time ejection; because the pry bar is arranged on the second push plate, when the second push plate pushes the pry bar to rotate, the rotation of the pry bar can squeeze out the first push plate, and then the second push rod is ejected, so as to realize secondary ejection; the secondary ejection structure of the utility model not only simplifies the complexity of the equipment, and one ejection mechanism can complete the secondary ejection work, but also greatly saves the equipment cost. At the same time, the use effect of the ejection mechanism is better, and the material strip can be effectively protected from being damaged after the secondary ejection, and the practicability is strong.

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0017] like Figure 1-2 As shown,

[0018] A secondary ejection mechanism of a lever structure comprises a push plate assembly, a push rod 1, a pry bar 2 and a push rod assembly; the push plate assembly comprises a first push plate 3, a second push plate 4 and a third push plate 5 arranged in sequence; the push rod assembly comprises a first push rod 6 and a second push rod 7, the first push rod 6 is fixedly connected to the second push plate 4, the second push rod 7 is fixedly connected to the first push plate 3, the second push plate 4 is also rotatably connected to the pry bar 2, and the third push plate 5 is connected to the push rod 1 at one end away from the first push plate 3; in this embodiment, since the pry bar 2 can be rotated under the push of the second push plate 4, and then the first push plate 3 is ejected after the rotation, thereby realizing the secondary ejection work, the design of the present application is ingenious, which greatly simplifies the structure of the secondary ejection or reduces the use of the ejection mechanism, and the use effect is better.

[0019] As a preferred embodiment; the secondary ejection mechanism also includes a first connecting plate 8 and a second connecting plate 9, the push plate assembly is arranged between the first connecting plate 8 and the second connecting plate 9, the push rod 1 is inserted into the first connecting plate 8, and the other ends of the first push rod 6 and the second push rod 7 are connected to the second connecting plate 9 and extend to the outside of the second connecting plate 9; it can be understood that the push rod 1 can move on the first connecting plate 8, the first push rod 6 and the second push rod 7 can move on the second connecting plate 9, and the push plate assembly is arranged between the first connecting plate 8 and the second connecting plate 9, so that the connection of this mechanism is more compact.

[0020] As a preferred embodiment, an abutment plate 10 is also provided between the first connecting plate 8 and the second connecting plate 9, and one end of the abutment plate 10 abuts against one end of the pry bar 2. By providing the abutment plate 10, the abutment plate 10 is in a stationary state, and the pry bar 2 can rotate along the lower end of the abutment plate 10 when rotating, providing a lever fulcrum, thereby effectively pushing out the first push plate 3.

[0021] As a preferred embodiment, the second push plate 4 is rotatably connected to the pry bar 2 via a rotating shaft 11 .

[0022] As a preferred embodiment, a return spring 12 is also fixedly mounted on the second connecting plate 9, and the other end of the return spring 12 is fixedly connected to the first push plate 3. By providing the return spring 12, the return spring 12 can not only effectively reset the first push plate 3 and the pry bar 2 (after losing the force of the push rod 1), but also the pry bar 2 can be smoother when ejecting the first push plate 3, and will not eject the first push plate 3 and the second push rod 7 all at once, thereby improving the quality of the secondary ejection.

[0023] The working principle of the utility model is as follows: the push rod 1 is pushed forward, thereby pushing the entire push plate assembly forward, and at the same time pushing out the first push rod 6 and the second push rod 7 (realizing one-time ejection). During the ejection process, the second push plate 4 will push the pry bar 2 to rotate. Since the second push rod 7 is arranged on the first push plate 3, the pry bar 2 can eject the first push plate 3 when rotating, and then eject the second push rod 7 (realizing secondary ejection). The secondary ejection method adopted in the present application aims to push the material belt out of the conveying channel for conveying, and can effectively protect the material belt. During the first ejection, the material belt can be effectively ejected from the equipment slot, and during the second ejection, the material belt can be directly pushed out into the conveying channel.

[0024] It should be pointed out that the main problem in the prior art is that two ejection mechanisms are generally used in the prior art to work. However, the use of two ejection mechanisms not only makes the equipment more complicated, but also greatly increases the cost of the equipment.

[0025] Therefore, after the improvement of the present application, the secondary ejection structure of the utility model not only simplifies the complexity of the equipment, one ejection mechanism can complete the secondary ejection work, but also greatly saves the equipment cost. At the same time, the use effect of the ejection mechanism is better, and the material strip can be effectively protected from being damaged after the secondary ejection.

[0026] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
