Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] This invention discloses a clamp 4 recirculation mechanism, such as... Figure 1-9 As shown, it includes: a first feeding line 1, a second feeding line 2, and a mold opening assembly 3. The first feeding line 1 and the second feeding line 2 are arranged vertically. Both the first feeding line 1 and the second feeding line 2 are used for horizontally transmitting the fixture 4. The mold opening assembly 3 is used to open the fixture 4. A first pushing assembly 5 for pushing the fixture 4 into the second feeding line 2 is installed on the first feeding line 1.

[0042] The second feeding line 2 is provided with a lifting machine 6 on one side for driving the clamp 4 to move up and down in the vertical direction. The second feeding line 2 is provided with a second pushing component 7 at one end relative to the first feeding line 1 for pushing the clamp 4 into the lifting machine 6. The lifting machine 6 is provided with a first discharge line 8 located below the first feeding line 1 on one side. The lifting machine 6 is provided with a third pushing component 9 for pushing the clamp 4 onto the first discharge line 8.

[0043] The first discharge line 8 is perpendicular to one end of the elevator 6 and the second discharge line 10 is provided. The first discharge line 8 is equipped with a fourth push-in component 14 for pushing the clamp 4 into the second discharge line 10.

[0044] The conveying direction of the clamp 4 on the first feed line 1 is parallel to the conveying direction of the clamp 4 on the second discharge line 10, and the conveying direction of the clamp 4 on the second feed line 2 is parallel to the conveying direction of the clamp 4 on the first discharge line 8.

[0045] It should be noted that the conveying direction of the clamp 4 on the first feed line 1 is parallel to the conveying direction of the clamp 4 on the second discharge line 10, and the conveying direction of the clamp 4 on the second feed line 2 is parallel to the conveying direction of the clamp 4 on the first discharge line 8. This provides a clamp 4 return mechanism. Since the feeding position of the first feed line 1 and the position of the second discharge line 10 are on the same side, it is convenient to return the clamp 4 and reduce the space occupied by the clamp 4 return mechanism.

[0046] like Figure 1 and Figure 2 As shown, it also includes a blocking component installed on the first feed line 1. The blocking component is located on one side of the first push-in component 5 and is used to prevent the clamp 4 from moving on the first feed line 1. It should be noted that by setting the blocking component, it is easy to prevent the clamp 4 from moving on the first feed line 1, and it is convenient for the first push-in component 5 to push the clamp 4.

[0047] like Figure 1 and Figure 2 As shown, the blocking assembly includes two blocking cylinders 15 arranged opposite to each other. It should be noted that the blocking action of the blocking cylinders 15 prevents the clamp 4 from moving on the first feed belt 12, so that the first pushing assembly 5 can push the clamp 4 onto the second feed belt 22.

[0048] like Figure 1 and Figure 2 As shown, the first feeding line 1 includes a first feeding frame 11, on which a first feeding belt 12 is wound, and a first feeding motor 13 for driving the first feeding belt 12 to move is installed on one side of the first feeding frame 11.

[0049] like Figure 1 and Figure 6 As shown, the second feeding line 2 includes a second feeding frame 21, on which a second feeding belt 22 is wound. A second feeding motor 23 for driving the second feeding belt 22 to move is installed on one side of the second feeding frame 21. It should be noted that the second feeding motor 23 drives the second feeding belt 22 to move on the second feeding frame 21, thereby causing the second feeding belt 22 to drive the clamp 4 to move horizontally.

[0050] like Figure 1-5 As shown, the mold opening assembly 3 includes a mold opening frame 31, on which an upper mold opening component 32 is installed. A lower mold opening component 33 and a positioning component 34 are installed on the first feeding line 1. The positioning component 34 is used to position and clamp the fixture 4 on the first feeding line 1. Both the upper mold opening component 32 and the lower mold opening component 33 are used to open the fixture 4.

[0051] It should be noted that there are two upper mold opening parts 32 and two lower mold opening parts 33. The clamp 4 contains an electronic detonator, which is clamped at both ends. The positioning part 34 clamps and positions the clamp 4 so that the clamp 4 is in the mold opening position. Under the mold opening action of the upper mold opening part 32 and the lower mold opening part 33, the clamp 4 is released from clamping the electronic detonator, which is convenient for the operator to manually demold.

[0052] like Figure 1-5As shown, the upper mold opening component 32 includes an upper mold opening cylinder 321 mounted on the mold opening frame 31. The telescopic rod of the upper mold opening cylinder 321 is fixedly connected to an upper mold opening base 322, and several upper mold opening wheels 323 are hinged on the upper mold opening base 322. It should be noted that the upper mold opening base 322 moves vertically by the upper mold opening cylinder 321, which in turn drives the upper mold opening wheels 323 to move, thereby releasing the clamps 4 from the electronic detonators.

[0053] like Figure 1-5 As shown, the lower opening mold component 33 includes a lower opening mold cylinder 331 installed on the side wall of the first feed line 1, and a lower opening module 332 is fixedly connected to the telescopic rod of the lower opening mold cylinder 331. It should be noted that the lower opening mold cylinder 331 drives the lower opening module 332 to move, thereby lifting the electronic detonator and releasing the clamp 4 from the electronic detonator.

[0054] like Figure 1-5 As shown, the positioning component 34 includes a positioning cylinder 341 installed on the first feeding line 1, and a positioning block 342 is fixedly connected to the telescopic rod of the positioning cylinder 341. It should be noted that the positioning cylinder 341 drives the positioning block 342 to move, thereby positioning and clamping the fixture 4 on the first feeding frame 11, which facilitates the mold opening assembly 3 to open the fixture 4.

[0055] like Figure 1-5 As shown, a stop cylinder 16 is installed on the first feed line 1, located on one side of the positioning member 34. The stop cylinder 16 is used to prevent the fixture 4 from moving on the first feed line 1. It should be noted that there are two stop cylinders 16. The blocking effect of the stop cylinders 16 facilitates the mold opening assembly 3 to open the fixture 4.

[0056] like Figure 1 and Figure 2 As shown, the first pushing assembly 5 includes a first pushing cylinder 51, and the telescopic rod of the first pushing cylinder 51 is fixedly connected to a first pushing plate 52. It should be noted that the first pushing cylinder 51 is installed on one side of the first feeding frame 11, and the first pushing cylinder 51 drives the first pushing plate 52 to move linearly, pushing the clamp 4 on the first feeding belt 12 into the second feeding line 2.

[0057] like Figure 1 and Figure 7 As shown, the elevator 6 includes an elevator frame 61, a lifting seat 62 slidably connected within the elevator frame 61, and an elevator motor 63 fixedly installed within the elevator 6 to drive the lifting seat 62 to move vertically. It should be noted that the elevator motor 63 drives the lifting seat 62 to move vertically within the elevator frame 61, receiving the clamp 4 from the second feed line 2 and moving it downwards. Through the pushing action of the third pushing component 9, the clamp 4 is pushed into the first discharge line 8.

[0058] like Figure 1 and Figure 6 As shown, the second pushing assembly 7 includes a second pushing base plate 71 vertically fixedly mounted on the second feeding line 2. A second pushing plate 72 is slidably connected to the second pushing base plate 71. A second pushing cylinder 73 for driving the second pushing plate 72 to move horizontally linearly is mounted on the second pushing base plate 71. It should be noted that the second pushing base plate 71 is vertically fixedly connected to the second feeding frame 21. The second pushing cylinder 73 drives the second pushing plate 72 to move linearly on the second pushing base plate 71, so that the second pushing plate 72 pushes the clamp 4 on the second feeding belt 22 into the lifting seat 62.

[0059] like Figure 1 and Figure 8 As shown, the first discharge line 8 includes a first discharge frame 81, on which a first discharge belt 82 is wound. A first discharge motor 83 for driving the first discharge belt 82 to move obliquely in a straight line is fixedly installed on the first discharge frame 81. It should be noted that a speed regulator for controlling the output torque of the first discharge motor 83 is fixedly installed on the first discharge frame 81; the first discharge motor 83 drives the first discharge belt 82 to move, causing the first discharge belt 82 to drive the clamp 4 to move for discharge.

[0060] like Figure 1 and Figure 7 As shown, the third pushing assembly 9 includes a third pushing base plate 91 fixedly installed inside the elevator 6. A third pushing plate 92 is slidably connected to the third pushing base plate 91. A third pushing cylinder 93 is installed on the third pushing base plate 91 to drive the third pushing plate 92 to move linearly. It should be noted that the third pushing base plate 91 is fixedly connected to the elevator 6 frame. The third pushing cylinder 93 drives the third pushing plate 92 to move on the third pushing base plate 91, so that the third pushing plate 92 pushes the clamp 4 inside the lifting seat 62 into the first discharge line 8.

[0061] like Figure 1 and Figure 9 As shown, the second discharge line 10 includes a second discharge frame 101, on which a second discharge belt 102 is wound. A second discharge motor 103 is fixedly installed on the second discharge frame 101 to drive the second discharge belt 102 to move obliquely in a linear fashion. It should be noted that the second discharge motor 103 drives the second discharge belt 102 to move, causing the second discharge belt 102 to drive the returning clamp 4 to discharge material, thus achieving the return flow of the clamp 4.

[0062] like Figure 1 and Figure 8As shown, the fourth pushing assembly 14 includes a fourth pushing cylinder 141, and the telescopic rod of the fourth pushing cylinder 141 is fixedly connected to a fourth pushing plate 142. It should be noted that the fourth pushing cylinder 141 drives the fourth pushing plate 142 to move linearly, so that the fourth pushing plate 142 pushes the clamp 4 on the first discharge line 8 onto the second discharge line 10, and discharges the material through the second discharge line 10.

[0063] Working principle: The conveying direction of the clamp 4 on the first feed line 1 is parallel to the conveying direction of the clamp 4 on the second discharge line 10, and the conveying direction of the clamp 4 on the second feed line 2 is parallel to the conveying direction of the clamp 4 on the first discharge line 8. This provides a clamp 4 return mechanism. Since the feeding position of the first feed line 1 and the position of the second discharge line 10 are on the same side, it is convenient to return the clamp 4 and reduce the space occupied by the clamp 4 return mechanism.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
