[0031] Please refer to Figures 1 to 6As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0033] This utility model provides a finished product collection device for a nut cold heading machine, including a cold heading machine body 1 and a collection mechanism 2. The collection mechanism 2 is located at the feeding port of the cold heading machine body 1, and a linkage mechanism 3 and a sound-generating mechanism 4 are arranged above the collection mechanism 2.

[0034] The collection mechanism 2 includes a main collection box 21 and a receiving plate 23 that is slidably connected inside the main collection box 21. Side guide buckets 26 and auxiliary collection boxes 27 are provided on both sides of the main collection box 21.

[0035] The linkage mechanism 3 includes a linkage plate 31 and guide blocks 33 fixedly connected to both sides below the linkage plate 31. A baffle plate 32 is fixedly connected above the linkage plate 31.

[0036] The sound-generating mechanism 4 includes multiple pneumatic cylinders 41 and a pneumatic sound-generating assembly 48, which includes a sound-generating base 481, a central tube 486 and a metal disc 484.

[0037] The main body 1 of the cold heading machine is a cold heading machine used in the prior art for producing flange nuts. Its feeding hopper is placed above the main collection box 21. The top cover 22 and the linkage plate 31 have the same cross section, and the baffle plate 32 passes through the top cover 22. Therefore, during the reciprocating movement of the linkage plate 31, the nuts can be prevented from entering the gap between the linkage plate 31 and the top cover 22. The baffle plate 32 plays a protective role. The bottom surface of the guide block 33 is a beveled surface. Therefore, during the downward movement, it will push the nuts below towards the side guide buckets 26 on both sides.

[0038] In a further embodiment, a top cover 22 is installed on the upper port of the main collection box 21, and pneumatic cylinders 41 are all embedded inside the top cover 22. The pneumatic sound-generating component 48 is installed above the top cover 22, and the linkage plate 31 is located between the top cover 22 and the receiving plate 23.

[0039] In this embodiment, the top cover 22 is provided with a circular groove for installing the pneumatic cylinder 41, and a groove for the material blocking plate 32 to pass through.

[0040] In a further embodiment, a drive motor 25 is installed on one side of the main collecting box 21, the output end of the drive motor 25 is provided with a cam 24 through a shaft, the cam 24 is in close contact with the bottom of the receiving plate 23, one end of the side guide hopper 26 is located above the auxiliary collecting box 27, and the other end is fixedly connected to the main collecting box 21.

[0041] In this embodiment, a door plate is further connected to one side of the main collecting box 21 through a hinge, so that it is convenient to take the nuts after the main collecting box 21 is full; the drive motor 25 and the cam 24 provide power for the up-down reciprocating movement of the receiving plate 23 in the prior art, so that the nuts can be uniformly dispersed above the receiving plate 23, avoiding accumulation; the main collecting box 21 has an opening at the side guide hopper 26, so that the excess nuts can be concentrated into the auxiliary collecting box 27 through the opening and the side guide hopper 26.

[0042] In a further embodiment, a piston 45 is slidably connected inside the pneumatic cylinder 41, the bottom of the piston 45 is fixedly connected with a connecting column 46, and the bottom end of the connecting column 46 is fixedly connected with the linkage plate 31.

[0043] In this embodiment, when the nuts continue to accumulate below the linkage plate 31, the movement of the receiving plate 23 will make the linkage plate 31 move up and down together, so that the airflow can be continuously injected into the inside of the concentrating pipe 486.

[0044] In a further embodiment, the upper end of the pneumatic cylinder 41 is provided with an air inlet end 42 and an air outlet end 43, one side of the sound emitting base 481 is provided with an air inlet head 485, and the air outlet end 43 is connected to the air inlet head 485 through a connecting pipe 44.

[0045] In this embodiment, the air inlet end 42 and the air outlet end 43 are both one-way, when the piston 45 moves up, the airflow only flows from the air outlet end 43 and the connecting pipe 44 to the inside of the concentrating pipe 486, and when the piston 45 moves down, the air inlet end 42 will supplement the gas into the inside of the pneumatic cylinder 41; one end of the connecting pipe 44 is connected to the air inlet head 485, but the other end is connected to the air outlet end 43.

[0046] In a further embodiment, the bottom of the sound emitting base 481 is threadedly connected with a mounting cover 482, the upper side of the mounting cover 482 is provided with a spring 483, a metal disc 484 is placed above the spring 483, and the metal disc 484 is located below the concentrating pipe 486.

[0047] When the inside of the concentration pipe 486 is continuously injected with gas, the gas injection hole 487 will spray out, thus the pressure is increased, thereby blowing to the metal disc 484, making the metal disc 484 vibrate with the spring 483 to generate sound, thereby reminding the user that the screw cap in the main collecting box 21 is full.

[0048] In further embodiments, one end of the concentration pipe 486 is in communication with the air inlet head 485, and the middle of the concentration pipe 486 is provided with a downward gas injection hole 487, and the upper portion of the sound generating base 481 is fixedly connected with a horn pipe 488.

[0049] In this embodiment, the horn pipe 488 is used to facilitate the amplification of the sound generated by the metal disc 484, thereby being more conveniently heard.

[0050] The working principle of the utility model is as follows:

[0051] When the cold header main body 1 produces flange screw caps, the driving motor 25 will also operate, thereby rotating the cam 24 and moving the receiving plate 23 up and down in the main collecting box 21. At this time, the produced screw caps can be evenly scattered after falling into the inside of the receiving plate 23. As the accumulation of screw caps increases, the lower portion of the linkage plate 31 will be gradually approached. When the bottom surface of the linkage plate 31 is flush, because the receiving plate 23 is always in an up-and-down moving state, the linkage plate 31 will also move up and down synchronously due to the accumulation of screw caps, thereby pushing the piston 45 to move up and down reciprocatingly. Thus, the pneumatic cylinder 41 will continuously inject air flow into the air inlet head 485 through the connecting pipe 44, and the air flow will enter the inside of the concentration pipe 486 and be sprayed out from the inside of the small gas injection hole 487, thereby impacting the metal disc 484 and generating vibration and sound, thereby reminding the staff that the screw caps in the main collecting box 21 are full, so that the touch sensor and the buzzer are not needed, thereby reducing the use cost.

[0052] During the process of moving the linkage plate 31 up and down by the screw caps accumulated above the main collecting box 21, the screw caps below the material guiding block 33 will be pushed by the material guiding block 33 to the side guide hopper 26, thereby guiding the screw caps to be collected into the inside of the auxiliary collecting box 27 through the side guide hopper 26. In this way, not only can the cold header main body 1 continuously produce screw caps for collection, but also the pneumatic sound generating assembly 48 can continuously generate sound for reminding.

Therefore, the present application is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the present application should also fall within the protection scope of the claims of the present application.
