The springs made by the spring machine body 1 fall on the conveying bucket 57, and then the springs pass through the conveying pipe 53 and the discharge conduit 55, and finally fall on the gasket 63 in the collecting barrel 61. Whenever a spring falls in the collecting barrel 61, the first motor 561 drives the discharge conduit 55 to rotate a certain angle through the transmission of the second pulley 563, the first pulley 562 and the belt 564, so that the springs are placed one by one in the collecting barrel 61 along the ring. When the springs are filled along a ring, the cylinder 52 drives the discharge conduit 55 to rise a certain distance through the connecting plate 54, and then the springs are placed one by one in the collecting barrel 61 along the ring. The made springs are led out by the discharge conduit 55, and the rotating mechanism 56 drives the discharge conduit 55 to rotate, and the cylinder 52 drives the discharge conduit 55 to rise, so that the springs are regularly discharged in the collecting barrel 61 in a ring shape, and are stacked up in sequence, so that the springs are neatly placed, the internal space of the collecting barrel 61 is reasonably utilized, and it is also convenient to take the springs out of the collecting barrel 61 later.

[0031] The rotating mechanism 56 includes a first motor 561 fixedly connected to the connecting plate 54 and a first pulley 562 fixedly connected to the exhaust duct 55. The first motor 561 is electrically connected to an external power supply and is controlled by an external control program. The output end of the first motor 561 is fixedly connected to a second pulley 563. The second pulley 563 and the first pulley 562 are connected via a belt 564.

When the number of springs located directly below the unloading mechanism 5 reaches a certain number, the second motor 622 will drive the disc 623 and the limit disc 624 to rotate. By utilizing the cooperation of the limit disc 624, the protruding rod 625 and the rotating disc 626, and the action of the clamping mechanism 65, the next collecting barrel 61 is moved to the bottom of the unloading mechanism 5, and then the springs continue to be collected.

[0034] Embodiment 2

[0035] Based on Example 1, see Figure 1-5 shown.

[0036] The positioning mechanism 2 includes a threaded rod 21 rotatably connected to the spring machine body 1 and a positioning groove 22 provided on the fixing frame 51, the threaded rod 21 is threadedly connected with an L-shaped plate 23, and the L-shaped plate 23 is connected with a positioning rod 25 used in conjunction with the positioning groove 22 through a reset mechanism 24, one side of the positioning rod 25 is set as an inclined surface, and one side of the fixing frame 51 is set as an inclined surface. By moving the support platform 3 to one side of the spring machine body 1 and fitting the side edge of the fixing frame 51 with the side edge of the L-shaped plate 23, when pushing the support platform 3, the fixing frame 51 squeezes the positioning rod 25, so that the positioning rod 25 moves, thereby causing the reset spring 242 to be compressed. When the support platform 3 and the fixing frame 51 fit with the spring machine body 1, the positioning rod 25 is pressed against the fixing frame 51, and the fixing frame 51 is pressed against the fixing frame 51. The positioning rod 25 and the positioning groove 22 are just aligned, so that under the action of the reset spring 242, the positioning rod 25 is stuck in the positioning groove 22, thereby fixing the spring machine body 1 and the support platform 3 together. When the spring machine body 1 needs to be repaired, the L-shaped plate 23 is supported and the threaded rod 21 is rotated to move the positioning rod 25 out of the positioning groove 22. At this time, the spring machine body 1 and the support platform 3 can be disassembled, and then the support platform 3 is removed to facilitate the maintenance of the spring machine body 1. By setting the positioning mechanism 2, the spring machine body 1 and the support platform 3 can be disassembled and assembled. After installation, the support platform 3 will not be offset, which is conducive to the collection of spring blanks. After disassembly, it is convenient to repair the spring machine body 1.

[0037] The reset mechanism 24 includes a connection block 241 fixedly connected to the positioning rod 25 and a reset spring 242 sleeved on the positioning rod 25 . The reset spring 242 is fixedly connected to the connection block 241 and the L-shaped plate 23 , respectively.

[0038] Embodiment 3

[0039] Based on Example 1, see Figure 7 and Figure 8 shown.

[0040] The clamping mechanism 65 includes an L-shaped arm 651 fixedly connected to the top of the rotating disk 626 and a first through slot 652 penetrating the top of the sleeve 64. The L-shaped arm 651 passes through the through hole 4 and is inserted into the sleeve 64. A second through slot 653 is penetrating the top of the L-shaped arm 651. A clamping plate 655 used in conjunction with the second through slot 653 is slidably connected to the first through slot 652 through a limiting mechanism 654. When the collection of the spring is full, When the cylinder 61 is moved away from the front of the unloading mechanism 5, the clamping plate 655 is lifted upward, and then the clamping plate 655 is pulled out of the second through groove 653. At this time, the collecting cylinder 61 and the L-shaped arm 651 can be separated, so that it is convenient to pick up the collecting cylinder 61 and pour out the spring. By setting the clamping mechanism 65, it is convenient to drive the collecting cylinder 61 to move and realize the collection of the spring, and it is also convenient to disassemble the collecting cylinder 61 and the delivery mechanism 62, so that it is convenient to pick up the collecting cylinder 61 and pour out the spring.

[0041] The limiting mechanism 654 includes a third through slot 6541 extending through the card plate 655 and a shaft rod 6542 fixedly connected to the first through slot 652. The shaft rod 6542 is slidably connected to the third through slot 6541. By setting the limiting mechanism 654, the card plate 655 can be prevented from detaching from the first through slot 652.

[0042] The working principle of the present invention is as follows: by moving the support platform 3 to one side of the spring machine body 1, and fitting the side of the fixing frame 51 with the side of the L-shaped plate 23, when pushing the support platform 3, the fixing frame 51 squeezes the positioning rod 25, so that the positioning rod 25 moves, so that the return spring 242 is forced to be in a compressed state, and when the support platform 3 and the fixing frame 51 fit with the spring machine body 1, the positioning rod 25 and the positioning groove 22 are just aligned, so that under the action of the return spring 242, the positioning rod 25 is stuck in the positioning groove 22, thereby fixing the spring machine body 1 and the support platform 3 together; thereafter, the spring manufactured by the spring machine body 1 falls on the conveying bucket 57 After that, the spring passes through the conveying pipe 53 and the discharge conduit 55, and finally falls on the gasket 63 in the collection barrel 61 (the spring falls on the gasket 63, which can reduce the shaking of the spring and is conducive to the subsequent placement of the spring). Whenever a spring falls into the collection barrel 61, the first motor 561 drives the discharge conduit 55 to rotate a certain angle through the transmission of the second pulley 563, the first pulley 562 and the belt 564, so that the springs are placed one by one in the collection barrel 61 along the ring. When the springs are fully placed along a ring, the cylinder 52 drives the discharge conduit 55 to rise a certain distance through the connecting plate 54, and then the springs are placed one by one in the collection barrel 61 along the ring (odd-numbered layers of springs are placed one by one). The number of springs in an odd-numbered layer is one more than the number of springs in an even-numbered layer. For example, when the number of springs in an odd-numbered layer is 10, the number of springs in an even-numbered layer is 9, so that the springs in the upper layer will be placed in the gap between the springs in the lower layer to avoid the springs being stuck together); thereafter, when the number of springs located directly below the feeding mechanism 5 reaches a certain number, the second motor 622 will drive the disc 623 and the limiting disc 624 to rotate, and by utilizing the cooperation of the limiting disc 624, the protruding rod 625 and the rotating disc 626, and the action of the clamping mechanism 65, the next collecting barrel 61 is moved to the bottom of the feeding mechanism 5, and then the springs are continued to be collected; thereafter, when the collecting barrel 61 filled with springs is removed from the feeding mechanism 5 is removed, the card plate 655 is lifted up, and then the card plate 655 is pulled out from the second through groove 653. At this time, the collection tube 61 and the L-shaped arm 651 can be separated, so that it is convenient to pick up the collection tube 61 and pour out the springs; thereafter, the empty collection tube 61 is installed on the L-shaped arm 651 to continue collecting springs; when the spring machine body 1 needs to be repaired, the L-shaped plate 23 is supported and the threaded rod 21 is rotated, so that the positioning rod 25 is moved out of the positioning groove 22 (the positioning mechanisms 2 on both sides perform the same operation), at this time, the spring machine body 1 and the support platform 3 can be disassembled, and then the support platform 3 is removed, so as to facilitate the maintenance of the spring machine body 1.

[0043] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
