[0043] The following is a further non-restrictive detailed description of the technical solution of the invention in conjunction with the preferred embodiments and the accompanying drawings. In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] like Figure 1 and Figure 2As shown, a riveting machine discharge device corresponding to a preferred embodiment of the present invention includes a discharge rack 1 for fixing a material tray (not shown) and a connecting shaft 2 fixedly connected to the discharge rack 1; the discharge rack 1 can drive the connecting shaft 2 to rotate. The connecting shaft 2 is connected to an angle adjuster 4 and a tensioning assembly 3. The angle adjuster 4 is connected to a fixed end 5. The material tray is connected to a feeding device (not shown), and the feeding device sends the material strip on the material tray to the processing area for processing (this is a prior art and will not be described here). Specifically, the connection method between the connecting shaft 2 and the angle adjuster 4 is: after the connecting shaft 2 is rotated in the feeding direction, it is connected to the angle adjuster 4. At this time, the tensioning assembly 3 stores elastic potential energy generated by the rotation of the connecting shaft; and the angle adjuster 4 prevents the connecting shaft 2 from rotating in a direction opposite to the feeding so that the elastic potential energy generated in the tensioning assembly 3 can be maintained. Among them, the rotation angle of the connecting shaft 2 can be adjusted according to actual needs, which can be one circle, two circles, three circles, etc., so that after the angle adjuster 4 is connected to the connecting shaft 2, the torque generated by the connecting shaft 2 rotating one circle, two circles, three circles, etc. stored in the tensioning component 3 is converted into the elastic potential energy of the tensioning component 3; thereby, the material rack 1 maintains a certain rotational force, so that the material belt on the material tray maintains a certain tension when being pulled.

[0045] The unloading frame 1 includes a mounting frame 14, a spindle 11, an adjustment handle 12 connected to the spindle 11, and a clamping portion 13. The unloading frame 1 rotates about the central axis H of the spindle 11. One end of the spindle 11 is fixedly connected to the adjustment handle 12, and the other end is connected to the connecting shaft 2. The spindle 11 can drive the connecting shaft 2 to rotate. Specifically, the spindle 11 and the connecting shaft 2 are fixedly connected via a flange 6. The spindle 11 is threadedly connected to the flange 6, and the connecting shaft 2 is fixedly connected to the flange 6. When the material tray is fed, the unloading frame 1 rotates with the material tray, causing the spindle 11 on the unloading frame 1 to drive the flange 6 and the connecting shaft 2 fixed to the flange 6 to rotate. The spindle 11 is also provided with a pair of tapered shafts 111. The pair of tapered shafts 111 are integrally formed with the spindle 11. Multiple clamping portions 13 are provided, and the multiple clamping portions 13 are evenly distributed around the outer circumference of the spindle 11. The clamping portion 13 includes a chuck 144 and a pair of connecting rods 131. A pair of connecting rods 131 are parallel to each other and at the same height. One end of the connecting rod 131 is connected to the chuck 144, and the other end abuts the tapered shaft 111. Specifically, a roller 133 is provided at the end of the connecting rod 131 abutting the tapered shaft 111. The roller 133 abuts the tapered shaft 111 to reduce frictional resistance when the connecting rod 131 moves relative to the tapered shaft 111. A connecting rod 131 is connected to each end of the chuck 144. The chuck 144 is also provided with a pair of first rotating shafts 141 for connecting the connecting rods 131. The first rotating shafts 141 extend through the connecting rod 131 and the chuck 144 to enable rotational connection between the connecting rod 131 and the chuck 144. The mounting frame 14 is provided with a second rotating shaft 143. The second rotating shaft 143 extends through the connecting rod 131 and the mounting frame 14 to enable rotational connection between the connecting rod 131 and the mounting frame 14. Specifically, the connecting rod 131 rotates relative to the mounting bracket 14 around the second rotation axis 143 .

[0046] Rotating the adjustment handle 12 causes the spindle 11, which is fixedly connected to the adjustment handle 12, to rotate, thereby controlling the distance between the threaded connection between the spindle 11 and the flange 6, thereby moving the spindle 11 forward or backward along the central axis H. The spindle 11 drives the connecting rod 131, which is in contact with it, to move. Specifically, the connecting rod 131 rotates about the second rotation axis 143, causing the end of the connecting rod 131 connected to the spindle 11 to swing in accordance with the movement of the spindle 11 in the direction of the central axis H. At this time, the end of the connecting rod 131 connected to the chuck 144 swings in the opposite direction. When the spindle 11 moves backward along the central axis H, the spindle 11 drives the connecting rod 131 to rotate clockwise, i.e., the end of the connecting rod 131 connected to the chuck 144 swings forward, while the end of the connecting rod 131 connected to the spindle 11 swings backward. At this time, the chuck 144 approaches the spindle 11, allowing the placement or removal of the tray. When the spindle 11 moves forward along the center axis H, the spindle 11 drives the connecting rod 131 to rotate counterclockwise, that is, the end of the connecting rod 131 connected to the chuck 144 swings backward, and the end of the connecting rod 131 connected to the spindle 11 swings forward. At this time, the chuck 144 gradually moves away from the spindle 11 and abuts against the inner ring of the material tray to fix the material tray.

[0047] The tensioning assembly 3 includes a mainspring 31 and a mainspring box 32 sleeved on the connecting shaft 2. The mainspring box 32 is provided with a mounting shaft 321. The inner ring of the mainspring 31 is fixedly connected to the connecting shaft 2, and the outer ring of the mainspring 31 is fixedly connected to the mounting shaft 321 (this is a prior art and will not be described in detail here). When the connecting shaft 2 rotates, the connecting shaft 2 drives the inner ring of the mainspring 31 to rotate, and the outer ring of the mainspring 31 remains stationary relative to the connecting shaft 2, thereby causing the mainspring 31 to generate elastic potential energy, causing the connecting shaft 2 to generate a rotational force, and then causing the unloading rack 1 connected to the connecting shaft 2 to generate a rotational force and put the material belt delivered by the material tray into a tensioned state. Preferably, bearings are provided between the mainspring box 32, the connecting shaft 2, and the fixed end 5.

[0048] Further references Figure 3 The connecting shaft 2 is provided with a slot 23 that mates with the inner ring of the mainspring 31. Furthermore, one end of the connecting shaft 2 is fixedly connected to the flange 6, and the other end is connected to the angle adjuster 4. Specifically, the connecting shaft 2 is connected to the inner ring of the mainspring 31 via the slot 23 (this is prior art and will not be described in detail here). The end of the connecting shaft 2 that connects to the angle adjuster 4 is provided with a groove 21 and a first stopper 22. The groove 21 is used to accommodate the angle adjuster 4. The first stopper 22 is disposed within the groove 21 and abuts the angle adjuster 4.

[0049] Further references Figure 4The fixed end 5 is provided with a second stopper 514 at one end connected to the angle adjuster 4. The fixed end 5 includes a fixing bracket 53, a torque limiter 51, and an adjustment assembly 52. ​​The second stopper 514 is fixed to the torque limiter 51. The fixing bracket 53 houses the torque limiter 51 and the adjustment assembly 52. ​​The torque limiter 51 includes a fixed disk 511, a sliding disk 512, and a ball 516 disposed between the fixed disk 511 and the sliding disk 512. The sliding disk 512 is connected to the tensioning assembly 3 and can drive the tensioning assembly 3 to rotate. Specifically, the sliding disk 512 is keyed to the mainspring barrel 32 via a connecting key 322, allowing the sliding disk 512 to drive the mainspring barrel 32 to rotate. The sliding disk 512 is connected to the angle adjuster 4, and the end of the sliding disk 512 connected to the angle adjuster 4 is fixedly connected to the second stopper 514. Preferably, the sliding disk 512 and the second stopper 514 are integrally formed. The other end of the sliding disk 512 is provided with a plurality of "V"-shaped grooves 515. One end of the fixed disk 511 is connected to the sliding disk 512, and the other end is connected to the adjustment assembly 52. ​​The fixed disk 511 is provided with a plurality of semicircular grooves 513 corresponding to the "V"-shaped grooves 515. A plurality of corresponding balls 516 are provided. The ball 516 is arranged in a chamber formed by the "V"-shaped grooves 515 and the semicircular grooves 513. The adjustment assembly 52 includes a spring 521 abutting against the torque limiter 51, a fixed shaft 522 and an adjustment knob 523. One end of the spring 521 abuts against the torque limiter 51, and the other end abuts against the fixed shaft 522. The adjustment knob 523 abuts against the fixed shaft 522, and the adjustment knob 523 is threadedly connected to the fixed end 5. The fixed shaft 522 is key-connected to the fixing frame 53, and the fixed shaft 522 can slide relative to the fixing frame 53 along the direction of the central axis H. Rotating the adjustment knob 523 adjusts its position relative to the fixed end 5, driving the fixed shaft 522 to move, thereby controlling the degree to which the fixed shaft 522 compresses the spring 521. At this point, the fixed disk 511, which abuts the spring 521, is pressed against the sliding disk 512 by the pressure from the spring 521, securing the ball 516 between the sliding disk 512 and the fixed disk 511. The ball 516 is held in a fixed position relative to the sliding disk 512 and the fixed disk 511 by the elastic force applied by the spring 521 to the fixed disk 511. When the torque applied to the sliding disk 512 from the connecting shaft 2 is sufficient to cause the ball 516 to overcome the elastic force applied by the spring 521 to the fixed disk 511, the ball 516 rolls out of the V-shaped groove 515, allowing the sliding disk 512 to rotate relative to the fixed disk 511, thus placing the torque limiter 51 in a slipping state. Furthermore, the above torque, which is sufficient to enable the ball 516 to overcome the elastic force applied to the fixed plate 511 by the spring 521, is greater than the torque generated by the elastic potential energy stored in the tensioning assembly 3 acting on the connecting shaft 2 in the initial installation state; and is less than the torque applied to the connecting shaft 2 by the feeding device when pulling the material belt.The torque limiter 51 maintains the sliding plate 512 and the fixed plate 511 in a relatively static state in the initial state. When the torque applied to the connecting shaft by the feeding device through the material belt acts on the sliding plate 512, the torque limiter 51 slips.

[0050] Further references Figure 5 and Figure 6 , one end of the angle adjuster 4 is connected to the connecting shaft 2, and the other end is connected to the fixed end 5. In addition, one end of the angle adjuster 4 is provided with a protrusion 411 that abuts against the first limit block 22, and the other end is provided with a protrusion 411 that abuts against the second limit block 514. Specifically, the angle adjuster 4 includes an angle adjustment seat 41. The angle adjustment seat 41 can be set to one or more. In this embodiment, multiple angle adjustment seats 41 are provided; multiple angle adjustment seats 41 are connected in sequence. Protrusions 411 are respectively provided on both sides of the angle adjustment seat 41. Specifically, the angle adjustment seat 41 includes a circular main body 412, and a protrusion 411 is respectively provided on the two end faces of the main body 412. The protrusion 411 and the main body 412 are integrally formed. By adjusting the relative position between the protrusions 411 and the protrusions 411 when they abut, the maximum elastic potential energy stored in the tensioning assembly 3 in the initial state can be adjusted.

[0051] Specifically, when the material strip is fed in a clockwise direction, the connecting shaft 2 is rotated to allow the tensioning assembly 3 to store a certain amount of elastic potential energy, and the angle adjuster 4 is installed on the connecting shaft 2 to prevent the connecting shaft 2 from rotating. The installation process of the angle adjuster 4 is as follows: the protrusion 411 of the angle adjustment seat 41 that abuts the connecting shaft 2, which is close to the connecting shaft 2, is rotated counterclockwise until it abuts the first limit block 22; the protrusion 411 of the next angle adjustment seat 41, which is close to the previous angle adjustment seat 41, is rotated counterclockwise until it abuts the protrusion 411 of the previous angle adjustment seat 41; and then the protrusion 411 of the next angle adjustment seat 41, which is close to the previous angle adjustment seat 41, is rotated counterclockwise until it abuts the protrusion 411 of the previous angle adjustment seat 41. After all angle adjustment seats 41 are installed, the sliding plate 512 is connected to the angle adjuster 4, and the second stopper 514 is positioned on the counterclockwise side of the protrusion 411 on one end of the angle adjustment seat 41 connected to the sliding plate 512. Simultaneously, the second stopper 514 abuts against the protrusion 411. At this point, when the connecting shaft 2 generates a rotational force due to the elastic potential energy stored in the tensioning assembly 3, causing the connecting shaft 2 to rotate counterclockwise, the first stopper 22 is restrained by the protrusion 411 on the angle adjustment seat 41 abutting against the first stopper 22. Furthermore, the protrusion 411 on the other end of the angle adjustment seat 41 is restrained by the protrusion 411 of the other angle adjustment seat 41 connected to it. Similarly, the protrusion 411 connecting the angle adjustment seat 41 to the sliding plate 512 is restrained by the second stopper 514, ultimately limiting the rotation of the connecting shaft 2. Therefore, the unloading rack 1 can generate a certain rotational force in its initial state after installation. When the unloading device is in use, the unloading rack 1 rotates clockwise and drives the connecting shaft 2 to rotate clockwise. At this time, the first limit block 22 rotates one circle clockwise and abuts against the protrusion 411, thereby driving the angle adjustment seat 41 fixed with this protrusion 411 to rotate clockwise. The protrusion 411 at the end of the angle adjustment seat 41 away from the first limit block 22 rotates one circle clockwise and abuts against the next angle adjustment seat 41, driving the next angle adjustment seat 41 to rotate; and so on. When the protrusion 411 abutting against the sliding disk 512 rotates one circle clockwise and abuts against the second limit block 514, the connecting shaft 2, under the pulling force of the feeding device connected to the rack, generates a torque sufficient to cause the torque limiter 51 to slip and transmits it to the angle adjuster 4, causing the angle adjuster 4 to overcome the elastic force applied by the spring 521 to the fixed disk 511 and cause the torque limiter 51 to slip.

[0052] In other words, by adjusting the number of angle adjusters 41, the maximum elastic potential energy stored in the tensioning assembly 3 can be controlled. Specifically, when the number of angle adjustment seats 41 is reduced, the number of rotations required for the angle adjuster 4 to rotate to abut against the sliding disk 512 and drive the torque limiter 51 to slip during use can be reduced, thereby controlling the maximum elastic potential energy stored in the tensioning assembly 3. The number of angle adjustment seats 41 can be selected based on the maximum number of rotations of the mainspring 31 or the tensioning force required for the material strip; to ensure that when the material strip has the required tensioning force and the mainspring 31 can reach the maximum number of turns, the angle adjuster 4 drives the torque limiter 51 to slip, thereby preventing the mainspring 31 from exceeding the maximum number of turns and being damaged.

[0053] The present invention can also control the maximum elastic potential energy generated by the tensioning assembly 3 by adjusting the relative position of the abutment of two adjacent angle adjustment seats 41. Specifically, when installing the angle adjuster 4, the protrusion 411 at one end of one angle adjustment seat 41 and the adjacent angle adjustment seat 41 is rotated clockwise until it abuts against the protrusion 411 of the previous angle adjustment seat 41; at this time, when the elastic potential energy of the tensioning assembly 3 generates a force that drives the connecting shaft 2 to rotate counterclockwise, this angle adjustment seat 41 is driven by the connecting shaft 2 to rotate counterclockwise until it abuts against the adjacent angle adjustment seat 41 and is restricted from rotating by the torque limiter 51, thereby reducing the elastic potential energy stored in the tensioning assembly 3, thereby achieving the size of the elastic potential energy stored in the tensioning assembly 3 in the initial state.

[0054] When the material strip is fed in a counterclockwise direction, the installation positions of the angle adjuster 4 and the second limit block 514 are opposite to the installation directions when the material strip is fed in a clockwise direction, but the working principles are the same and will not be repeated here.

[0055] During installation, connect the tensioning assembly 3, connecting shaft 2, and unloading frame 1. Rotate connecting shaft 2 to store a certain amount of elastic potential energy in the tensioning assembly 3. Install the angle adjuster 4 on the connecting shaft 2 and then install the fixed end 5. Control the adjustment knob 523 to control the torque required to slip the torque limiter 51.

[0056] During use, the feed rack is mounted on the unloading rack 1 and the adjustment handle 12 is rotated to secure the rack. The feed rack rotates under the action of the feeding device, driving the unloading rack 1 to rotate. This, in turn, causes the connecting shaft 2 connected to the unloading rack 1 to rotate, driving the multiple angle adjustment seats 41 to rotate as well. When the protrusion 411 of the angle adjustment seat 41 abuts the second stop block 514, the feed tray rotates further, causing the angle adjuster 4 to cause the torque limiter 51 to slip, causing the sliding plate 512 to rotate with the angle adjuster 4. The sliding plate 512 then drives the mainspring barrel 32 to rotate. At this point, the mainspring barrel 32 rotates synchronously with the connecting shaft 2, while the outer ring connected to the mainspring barrel 32 and the inner ring connected to the connecting shaft 2 remain relatively stationary.

[0057] like Figure 7 As shown, the present invention also provides a riveting machine discharge method, comprising the following steps:

[0058] Installation of the tensioning assembly: Connect the tensioning assembly 3 that can store elastic potential energy to the material rack 1 for mounting the material tray; preferably, the tensioning assembly 3 is connected to the material rack 1 through a connecting shaft 2.

[0059] Elastic potential energy storage: The unloading rack 1 is rotated along the feeding direction F, and the tensioning component 3 converts the torque generated by the rotation of the unloading rack 1 into elastic potential energy and stores it;

[0060] Angle adjuster installation: connect the tensioning assembly 3 to the angle adjuster 4 that prevents the unloading rack 1 from rotating in the direction opposite to the feeding direction F. The angle adjuster 4 prevents the release of the elastic potential energy of the tensioning assembly 3;

[0061] Angle adjuster fixing: fix the angle adjuster 4.

[0062] Material tray installation: install the material tray on the material rack 1; make the multiple chucks 144 of the material rack 1 contact with the inner circle of the material tray and fix the material tray.

[0063] Feeding: Pull the material belt on the tray along the feeding direction F, the unloading rack 1 and the angle adjuster 4 rotate synchronously, and the tensioning component 3 further converts the torque generated by the rotation of the unloading rack 1 into elastic potential energy and stores it;

[0064] The torque limiter slips: the angle adjuster 4 rotates a certain angle and contacts the second limit block 514 of the torque limiter 51. The angle adjuster 4 applies a torque to the torque limiter 51 that causes the torque limiter 51 to slip. The angle adjuster 4 drives the sliding plate 512 of the torque limiter 51 to rotate.

[0065] The tensioning assembly rotates synchronously: the sliding plate 512 of the torque limiter 51 drives the tensioning assembly 3 to rotate synchronously with the unwinding rack 1. The tensioning assembly 3 stops and converts the torque generated by the rotation of the unwinding rack 1 into elastic potential energy and stores it.

[0066] The step of "angle adjuster fixing" includes:

[0067] Connect the angle adjuster 4 to the torque limiter 51;

[0068] The sliding disc 512 of the torque limiter 51 is connected to the tensioning assembly 3 to adjust the torque required for the torque limiter 51 to slip.

[0069] According to the above description, the unloading device of the present invention, through the cooperation of the tensioning assembly 3 and the angle adjuster 4, enables the unloading rack 1 to have a certain rotational force in the initial state, thereby putting the material strip pulled out of the material tray installed on the unloading rack 1 into a tensioned state. By providing a torque limiter 51 and connecting the sliding disk 512 to the spring box 32, the torque limiter 51 slips after the spring 31 rotates a certain number of times, preventing the spring 31 from being damaged due to excessive rotation, thereby improving the stability and safety of the equipment. By providing multiple angle adjustment seats 41, the number of rotations of the spring 31 during use can be controlled, and the operation is convenient and the structure is simple.
