[0036] Example:

[0037] like Figure 1-7As shown, this application discloses a feeding mechanism for a feeder, comprising a feeding plate 10, a first drive mechanism 20 for driving the feeding plate 10 to reciprocate linearly along a first direction, a vacuum nozzle assembly 30 cooperating with the feeding plate 10, a second drive mechanism 40 for driving the vacuum nozzle assembly 30 to reciprocate linearly along the first direction, a first opening and closing frame 50 and a second opening and closing frame 60 cooperating with the vacuum nozzle assembly 30, a third drive mechanism 70 for driving the first opening and closing frame 50 to reciprocate linearly along a second direction, and a third drive mechanism 70 for driving the second opening and closing frame 60 to reciprocate linearly along a second direction. A fourth drive mechanism 80 performs linear reciprocating motion. The third drive mechanism 70 drives the first opening and closing frame 50, and the fourth drive mechanism 80 drives the second opening and closing frame 60 to move closer or further apart. Both the first opening and closing frame 50 and the second opening and closing frame 60 are equipped with two support rods 91 and a fifth power source 92 that drives the two support rods 91 to perform linear reciprocating motion along a third direction. Through the above structural design, not only can automatic feeding of high-elasticity elastic bands be achieved, greatly improving production efficiency, but also the intensity of manual labor is reduced, which is beneficial to maintaining the health of employees. In this embodiment, the first direction is... Figure 1 The X direction in the middle, the second direction is Figure 1 In the Y direction, the third direction is Figure 1 The Z direction in the equation.

[0038] In this embodiment, multiple highly elastic bands are stacked sequentially on the material support plate 10. The first drive mechanism 20 drives the material support plate 10 upward, conveying the material to a higher position. The second drive mechanism 40 drives the vacuum nozzle assembly 30 downward. After the vacuum nozzle assembly 30 adsorbs the material at the top, the second drive mechanism 40 drives the vacuum nozzle assembly 30 upward. Since the material is a ring-shaped object, the lower half of the material separates from the upper half under the action of gravity, making the entire material roughly ring-shaped. The first opening and closing frame 50 driven by the third drive mechanism 70 and the second opening and closing frame 60 driven by the fourth drive mechanism 80 approach each other. When the first opening and closing frame 50 and the second opening and closing frame 60 are roughly at the material, the two fifth power sources 92 respectively drive two support rods 91 to extend into the through holes of the ring-shaped material. The vacuum nozzle assembly 30 stops adsorption, and the material naturally falls onto the four support rods 91 on the first opening and closing frame 50 and the second opening and closing frame 60. At this time, the first opening and closing frame 50 driven by the third drive mechanism 70 and the second opening and closing frame 60 driven by the fourth drive mechanism 80 move away from each other, so that the material is stretched and tightened on the four support rods 91. The two fifth power sources 92 drive the two support rods 91 to retract respectively. The first drive mechanism 70 and the second drive mechanism 80 move synchronously to send the material to the two expansion wheels of the feeder. The first opening and closing frame 50 driven by the third drive mechanism 70 and the second opening and closing frame 60 driven by the fourth drive mechanism 80 move closer to each other again, so that the material naturally rests on the four support rods 91 of the first opening and closing frame 50 and the second opening and closing frame 60. The two fifth power sources 92 drive the two support rods 91 to extend again, so that the material is placed on the two expansion wheels of the feeder. After the two fifth power sources 92 drive the two support rods 91 to retract again, the two expansion wheels tighten the material to facilitate subsequent processing. Finally, after each working unit is reset, the next material feeding operation begins.

[0039] Specifically, the first drive mechanism 20 includes a first power source 21, which in this embodiment is a motor, a first drive wheel 22 mounted on the output shaft of the first power source 21, and a first driven wheel 24 cooperating with the first drive wheel 22 via a first belt 23. A first linkage block 25 is fixed on the first belt 23, and the material support plate 10 is mounted on the first linkage block 25. Through the above structural design, the first power source 21 drives the first drive wheel 22 to rotate. While the first drive wheel 22 drives the first driven wheel 24 to rotate via the first belt 23, it also drives the first linkage block 25 to perform linear reciprocating motion in the first direction, that is, to move in the vertical direction of the present invention, thereby enabling the material support plate 10 to move up and down.

[0040] Specifically, a vertical plate 26 is also provided between the first driving mechanism 20 and the material support plate 10. The vertical plate 26 is vertically mounted on a base plate. Two guide rods 27 are provided on one side of the material support plate 10 relative to the vertical plate 26. There is a limiting space between the guide rods 27 and the vertical plate 26, thereby limiting the material stacked on the material support plate 10 and preventing it from tipping over when moving up and down.

[0041] Specifically, each end of the material support plate 10 is provided with a movable plate, and each movable plate is provided with two guide sleeves 28. Each guide sleeve 28 is sleeved on the guide rod 29 and can move linearly back and forth along the guide rod 29. The guide rod is installed on the side plates at both ends of the vertical plate 26. Through the above structural design, it can be ensured that the material support plate 10 can move in the up and down direction without deviation or shaking, thus ensuring the stable operation of the material support plate 10.

[0042] Specifically, the second driving mechanism 40 includes a second power source 41, which in this embodiment is a cylinder, and also includes a bracket 42 and a vacuum nozzle assembly mounting bracket 43. The bracket 42 is connected to the piston rod of the second power source 41. The vacuum nozzle assembly mounting bracket 43 is provided on the bracket 42, and the vacuum nozzle assembly 30 is mounted on the vacuum nozzle assembly mounting bracket 43. The bracket 42 is also provided with four vacuum connectors 44. Each of the vacuum connectors 44 is connected to the four nozzles of the vacuum nozzle assembly 30 through a pipeline. Through the above structural design, the second power source 41 drives the bracket 42 to move up and down, thereby driving the vacuum nozzle assembly 30 to move up and down to complete the adsorption or desorption of materials.

[0043] As a preferred embodiment, each of the vacuum connectors 44 is provided with a silencer 45 on its side. By providing the silencer 45, the noise generated when air enters and exits the vacuum connector can be effectively absorbed and suppressed, thereby providing a quieter working environment and helping to protect the hearing health of the operators.

[0044] Specifically, the third drive mechanism 70 includes a third power source 71, which in this embodiment is a motor; a third drive wheel 72 mounted on the output shaft of the third power source 71; and a third driven wheel 74 cooperating with the third drive wheel 72 via a third belt 73. A third linkage block 75 is fixed on the third belt 73, and the first opening and closing frame 50 is mounted on the third linkage block 75. The fourth drive mechanism 80 includes a fourth power source 81, which in this embodiment is a motor; a fourth drive wheel 82 mounted on the output shaft of the fourth power source 81; and a third driven wheel 74 cooperating with the third drive wheel 72 via a fourth belt 83. The fourth driven wheel 84 is coupled with the fourth driven wheel 82. A fourth linkage block 85 is fixed on the fourth belt 83. The second opening and closing frame 60 is installed on the fourth linkage block 85. Through the above structural design, the third power source 71 drives the third driving wheel 72 to rotate. The third driving wheel 72 drives the third driven wheel 74 to rotate through the third belt 73, and at the same time drives the third linkage block 75 to make linear reciprocating motion in the second direction, that is, to move in the left and right direction of the present invention, so that the first opening and closing frame 50 can move left and right. Similarly, the fourth power source 81 can drive the second opening and closing frame 60 to move left and right, so that the first opening and closing frame 50 and the second opening and closing frame 60 move closer or further apart.

[0045] In a preferred embodiment, each of the support rods 91 is provided with a stop rod 93 on its side. The stop rod 93 is approximately L-shaped, and the two stop rods 93 are arranged opposite each other. The two stop rods 93 are respectively installed on two stop rod seats, and the two stop rod seats are fixed on the first opening and closing frame 50 or the second opening and closing frame 60. The stop rod seats are provided with through holes for the support rods 91 to move through. With the above structural design, when the fifth power source 92 drives the two support rods 91 to retract, the two stop rods 93 can block the material and prevent the material from retracting with the support rods 91.

[0046] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, high degree of automation, and high production efficiency.

[0047] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
