[0023] This utility model provides an automatic continuous feeding mechanism for PU foam sheets with effective material control, including a frame 101, a lifting and translating unit 102, multiple sets of needle-punching assemblies, a conveying assembly, and two sets of material-supporting assemblies. Each set of needle-punching assemblies includes a connecting seat 103, two spring rods 104, a needle-punching seat 105, and two sets of piercing elements. The lifting and translating unit is located on the upper surface of the frame 101. The multiple sets of needle-punching assemblies are all located below the lifting and translating unit 102. The connecting seat 103 is fixedly connected to the lifting and translating unit 102. One end of each of the two spring rods 104 is connected to the connecting seat 103, and the other end of each spring rod 104 is connected to the needle-punching seat 105. The two sets of piercing elements are symmetrically arranged on both sides of the needle-punching seat 105. The conveying assembly is located on one side of the frame 101, and the two sets of material-supporting assemblies are symmetrically arranged on the frame 101.
[0024] In this embodiment, PU foam sheets are stacked under the piercing elements. Then, the lifting and translating unit 102 drives multiple connecting seats 103 to move downward. The connecting seats 103 drive the needle-piercing seats 105 to move downward via two spring rods 104. The needle-piercing seats 105 drive two sets of piercing elements to move downward until the piercing elements are in contact with the PU foam sheets. The piercing elements then pierce the PU foam sheets. The lifting and translating unit 102 moves the PU foam sheets upward to the conveying position. The lifting and translating unit 102 then moves the PU foam sheets forward into the conveying assembly. The rear of the PU foam sheets are supported by two sets of material-supporting assemblies. After that, the piercing elements are released. Finally, the conveying assembly transports the PU foam sheets forward into the rolling glue machine.
[0025] Furthermore, each set of piercing components includes a first cylinder 106, a connecting plate 107, and multiple piercing needles 108. The first cylinder 106 is fixedly connected to the piercing seat 105, the output end of the first cylinder 106 is fixedly connected to the connecting plate 107, one end of each of the multiple piercing needles 108 is fixedly connected to the connecting plate 107, and the other end of each of the multiple piercing needles 108 passes through the piercing seat 105.
[0026] In this embodiment, when the output end of the first cylinder 106 retracts, the connecting plate 107 drives multiple needles 108 to extend from the needle seat 105 and pierce the PU foam. When the output end of the first cylinder 106 extends, the connecting plate 107 drives multiple needles 108 to retract into the needle seat 105.
[0027] Furthermore, the conveying assembly includes two mounting plates 109, a drive roller 110, a drive motor 111, a driven roller 112, and two sets of lifting components. Both mounting plates 109 are fixedly connected to the frame 101. The two ends of the drive roller 110 are rotatably connected to the two mounting plates 109 respectively. The drive motor 111 is fixedly connected to one of the mounting plates 109, and the output end of the drive motor 111 is fixedly connected to the drive roller 110. The two sets of lifting components are respectively disposed on the two mounting plates 109, and the driven roller 112 is rotatably connected to the two sets of lifting components respectively.
[0028] In this embodiment, after the PU bubble sheet is fed between the active roller 110 and the driven roller 112, the two sets of lifting components drive the driven roller 112 to move downward to clamp the PU bubble sheet. Then, the active roller 110 is driven to rotate by the drive motor 111, thereby conveying the PU bubble sheet forward into the rolling machine.
[0029] Furthermore, each set of lifting components includes a slide rail 113, a slide plate 114, and a second cylinder 115. The slide rail 113 is fixedly connected to the corresponding mounting plate 109, the slide plate 114 is slidably connected to the slide rail 113, the second cylinder 115 is fixedly connected to the corresponding mounting plate 109, and the output end of the second cylinder 115 is fixedly connected to the slide plate 114.
[0030] In this embodiment, the second cylinder 115 is activated, and the output end of the second cylinder 115 drives the slide plate 114 to slide on the slide rail 113. The slide plate 114 drives the driven roller 112 to move downward.
[0031] Furthermore, the conveying assembly also includes a synchronizing link 116, two gears 117 and two racks 118. The two racks 118 are fixedly connected to the two mounting plates 109 respectively. The two ends of the synchronizing link 116 are rotatably connected to the two sliding plates 114 respectively. The two gears 117 are fixedly connected to the two ends of the synchronizing link 116 respectively and mesh with the corresponding racks 118 respectively.
[0032] In this embodiment, the movement of the two sliding plates 114 drives the synchronous connecting rod 116 to move, and the synchronous connecting rod 116 drives the two gears 117 to rotate on the corresponding racks 118, thereby preventing jamming caused by the asynchronous lifting and lowering of the two second cylinders 115.
[0033] Furthermore, the conveying assembly also includes a transition bracket 119, which is rotatably connected to the two mounting plates 109 respectively.
[0034] In this embodiment, the transition bracket 119 is connected to the rolling machine to facilitate the conveying of PU foam sheets.

[0036] In this embodiment, the rotary cylinder 120 is activated, which drives the round rod 121 to rotate to the bottom of the PU bubble, thereby supporting the PU bubble and preventing it from tearing due to jamming during transportation.
[0037] The beneficial effects of this utility model are as follows: The transition bracket 119 is connected to the rolling machine. PU foam sheets are stacked below multiple needle-piercing seats 105. Then, the lifting and translating unit 102 drives multiple connecting seats 103 to move downwards. The connecting seats 103, through two spring rods 104, drive the needle-piercing seats 105 downwards until the needles 108 are in contact with the PU foam sheets. Then, the output end of the first cylinder 106 retracts, causing the connecting plate 107 to drive multiple needles 108 to extend from the needle-piercing seats 105 and pierce the PU foam sheets. Then, the lifting and translating unit 102 moves upwards, raising the PU foam sheets to the conveying position. Then, the lifting and translating unit 102 drives the PU foam sheets forward, positioning them between the driving roller 110 and the driven roller 112. The second cylinder 115 drives the slide plate 114 to move downwards, which in turn drives the driven roller 112 to move downwards, thereby clamping the PU bubble sheet. Then, the rotary cylinder 120 is activated, which drives the round rod 121 to rotate to the bottom of the PU bubble sheet, thereby supporting the PU bubble sheet. Afterwards, the output end of the first cylinder 106 extends, causing the connecting plate 107 to drive multiple needles 108 to retract into the needle seat 105, thereby releasing the PU bubble sheet. Finally, the drive motor 111 drives the active roller 110 to rotate, thereby conveying the PU bubble sheet forward into the rolling machine. This method can effectively solve the problem in the prior art that PU bubble sheets are usually fed into the rolling machine manually, which is very time-consuming and labor-intensive, and the PU bubble sheets are easily contaminated during manual feeding.
