[0042] Specifically, the stacked upper box covers 6 are placed on the feeding base 2, and the stacked upper box covers 6 are placed on the supporting plane formed by the support block 24 and the support platform 23. The stacked upper box covers 6 can be stably supported by the supporting plane, and the detection sensor 25 detects the situation of the stacked upper box covers 6 on the support platform 23 to ensure the accuracy of the transportation of the stacked upper box covers 6. At the same time, the detection sensor 25 and the lifting ensure continuous rising feeding.

[0043] Furthermore, the jacking drive component includes a jacking cylinder 13, the jacking cylinder 13 is arranged on the feeding rack 1, the feeding rack 1 is provided with a jacking slide rail 14, the jacking slide rail 14 is slidably provided with a jacking plate 15, the jacking plate 15 is driven and connected to the jacking cylinder 13, the feeding base 2 is arranged on the jacking plate 15, and the jacking cylinder 13 is used to drive the feeding base 2 on the jacking plate 15 to reciprocate along the jacking slide rail 14.

[0044] Furthermore, the lifting cylinder 13 is used to drive the feeding base 2 on the lifting plate 15 to reciprocate along the lifting slide rail 14. The lifting cylinder 13 drives the feeding base 2 on the lifting plate 15 to move along the conveying channel 72, so that the stacked upper box covers 6 on the supporting plane move upward to the loading station 74 located in the middle of the guide frame 7, thereby realizing the automation of the conveying of the stacked upper box covers 6 and realizing the vertical conveying of the stacked upper box covers 6, which can effectively reduce the labor intensity of workers and improve production efficiency.

[0045] Furthermore, the guide frame 7 further includes a guide plate 16 , which is disposed on the feed frame 1 . The guide plate 16 and a plurality of guide plates 71 form a conveying channel 72 to guide the stacked box covers 6 .

[0046] Specifically, a conveying channel 72 is formed by the guide plate 16 and multiple guide plates 71 to guide the stacked upper box cover 6. By utilizing its guiding function, the workpiece can quickly enter the discharge station 75 at the top of the guide frame 7, avoiding the stacked upper box cover 6 from getting stuck in the conveying channel 72. It can guide the stacked upper box cover 6 and protect the stacked upper box cover 6.

[0047] Furthermore, the spring adjustment component 8 includes an adjustment seat 81, which is arranged on the material guide plate 71, and a first table 82 is provided on the adjustment seat 81, and second tables 83 are provided on both sides of the first table 82. The first table 82 is higher than the second table 83 so that a stepped structure is formed on the adjustment seat 81, and spring pieces are provided on both the first table 82 and the second table 83, and an accommodating groove for accommodating a single upper box cover is formed between the spring piece on the first table 82 and the spring piece on the second table 83.

[0048] Specifically, the upper box cover at the top of the stacked upper box covers 6 is grasped by the external material-picking device (manipulator, suction cup device) and the lifting cylinder 41 drives the support rod 52 upward. The edge of the upper box cover at the top of the stacked upper box covers 6 squeezes the spring piece 84 on the second table 83 to cause it to be slightly deformed. Then, the edge of the upper box cover at the top of the stacked upper box covers 6 is stuck in the accommodating groove for accommodating a single upper box cover, thereby separating the single upper box cover from the stacked upper box covers 6. The above operation is repeated to release the upper box covers from the stacked upper box covers 6 one by one. This arrangement represents

[0049] It replaces manual work and can coordinate with the packaging machine, greatly improving work efficiency;

[0050] At the same time, the single upper box cover located in the accommodating groove is driven by the external material-retrieving equipment to squeeze the single spring piece 84 located on the first table 82, causing it to deform slightly and then easily detach from the spring piece adjustment component 8 to complete the unloading of the upper box covers one by one, thereby realizing the separation operation of the stacked upper box covers 6 and saving the labor intensity and operation time of the operator.

[0051] Furthermore, the spring piece includes a spring piece 84, a waist-shaped groove 85 is provided on the spring piece 84, a mounting hole matching the waist-shaped groove 85 is provided on the adjustment seat 81, and a fixing block 86 is provided on the spring piece 84.

[0052] Specifically, the fixing block 86 is connected to the mounting hole by screws to fix the spring piece 84 on the adjustment seat 81. By adjusting the relative position of the spring piece 84 and the fixing block 86, the extension amount of the spring piece 84 out of the adjustment seat 81 is adjusted to ensure that a single upper box cover can be smoothly accommodated in the clamping groove, thereby ensuring the consistency of the extension amount of the spring piece 84, improving product yield, and improving production efficiency. At the same time, adjusting the extension amount of the spring piece 84 out of the adjustment seat 81 can also clamp upper box covers of different sizes.

[0053] Furthermore, the spring adjustment component 8 also includes a blowing hole 87, which is arranged on the guide plate 71. The blowing hole 87 is connected to the air valve 88. The center point of the blowing hole 87 is located on the second table 83 or on the accommodating groove. The blowing hole 87 is used to blow air on the stacked upper box cover 6 to separate the upper box cover located on the top of the stacked upper box cover 6.

[0054] Specifically, the air valve 88 is connected to an air blowing device such as an air pump, and is abutted against the upper box cover at the top of the stacked upper box covers 6 through the spring piece 84 located on the second table 83, so that an opening is formed between the upper box cover at the top of the stacked upper box covers 6 and the stacked upper box covers 6, and air is blown to the stacked upper box covers 6 through the blowing hole 87 to separate the upper box covers at the top of the stacked upper box covers 6, thereby realizing rapid separation of the upper box covers adsorbed together, effectively ensuring that the stacked upper box covers 6 are truly separated, and ensuring that the upper box covers are unloaded one by one.

[0055] Furthermore, the conveying component 5 includes a conveying bracket 51, which is arranged on the conveying base 53, and the conveying base 53 is slid on the substrate 54. A conveying cylinder 55 is provided on the substrate 54, and the conveying cylinder 55 is driven and connected to the conveying base 53. The conveying cylinder 55 is used to drive the conveying bracket 51 to reciprocate toward the stacked box cover 6 of the loading station 74.

[0056] Specifically, the conveying cylinder 55 drives the conveying bracket 51 to move toward the stacked upper box cover 6 of the loading station 74, and the conveying bracket 3 receives the stacked upper box cover 6, thereby achieving the technical effect of convenient, fast and automatic material receiving, and ensuring the stability of the stacked upper box cover 6 transportation.

[0057] Furthermore, the conveying bracket 51 includes two support rods 52, which are arranged at intervals on the conveying base 53, and the two support rods 52 are respectively located on both sides of the support platform 23. The support platform 23 is provided with a slot 26 matching the support rod 52. The support rod 52 is driven by the conveying cylinder 55 and is passed through the slot 26 and conveys the stacked box covers 6 on the support platform 23 under the drive of the power component 4.

[0058] Specifically, the conveying cylinder 55 drives the conveying bracket 51 to move toward the stacked upper box cover 6 of the loading station 74, and the support rod 52 is driven by the conveying cylinder 55 to pass through the slot 26. At this time, the support rod 52 is located on both sides of the support platform 23. The conveying frame 3 can accurately position and fix the stacked upper box cover 6, that is, to achieve secondary positioning. It occupies a small space, effectively reduces the use length of the jacking cylinder 13, and is low-carbon and environmentally friendly.

[0059] Furthermore, the power component 4 includes a lifting frame, which is arranged on the conveying frame 3. A lifting cylinder 41 is provided on the lifting frame. The piston rod end of the lifting cylinder 41 is drive-connected to the base plate 54. A guide rod 42 is provided on the base plate 54. The guide rod 42 is passed through the guide sleeve 43 on the lifting frame.

[0060] Specifically, the lifting cylinder 41 drives the base plate 54 to move to the loading station 74, so that the support rod 52 is driven by the conveying cylinder 55 to pass through the slot 26, ensuring the accuracy of the support rod 52 in picking up the material. At the same time, the lifting cylinder 41 lifts the stacked upper box cover 6 on the support platform 23 and conveys the stacked upper box cover 6 to the unloading station 75 located on the top of the guide frame 7. The stacked upper box cover 6 is driven by the lifting cylinder 41 for secondary conveying, which effectively reduces the use stroke of the lifting cylinder 13 and reduces production costs. At the same time, the stacked upper box cover 6 is guided by the guide frame 7 during the conveying process, which can further ensure the accuracy of conveying.

[0061] Usage process:

[0062] The stacked upper box cover 6 is placed on the feeding base 2, and the stacked upper box cover 6 is placed on the supporting plane formed by the support block 24 and the support platform 23. At this time, the stacked upper box cover 6 enters the conveying channel 72 from the upper box cover feeding end 73, and the jacking cylinder 13 drives the feeding base 2 on the jacking plate 15 to move along the conveying channel 72, so that the stacked upper box cover 6 on the supporting plane moves upward to the loading station 74 in the middle of the guide frame 7, and the lifting cylinder 41 drives the base plate 54 to move to the loading station 74, and the conveying cylinder 55 drives the conveying bracket 51 to move toward the stacked upper box cover 6 of the loading station 74. The support rod 52 is driven by the conveying cylinder 55 to pass through the slot 26. At this time, the support rod 52 is located on both sides of the support platform 23, and is driven by the power component 4 to jack up the stacked upper box cover 6 on the support platform 23 and convey the stacked upper box cover 6 to the unloading station 75 at the top of the guide frame 7;

[0063] At this time, the lifting cylinder 13 drives the feeding base 2 on the lifting plate 15 to move along the conveying channel 72 and descend to the origin. At this time, manual replenishment of materials can be carried out on the feeding base 2 to achieve uninterrupted replenishment of materials without stopping the machine.

[0064] The upper box cover 6 of stacking is conveyed by the guide plate 16 and multiple guide plates 71 to form a conveying channel 72 to guide the upper box cover 6 of stacking. After the upper box cover 6 of stacking is conveyed to the discharge station 75, the upper box cover at the top of the stacking upper box cover 6 is grasped by the external material picking device (manipulator, suction cup device) and the lifting cylinder 41 drives the support rod 52 upward to lift the upper box cover. The edge of the upper box cover at the top of the stacking upper box cover 6 squeezes the spring piece 84 on the second table 83 to cause it to be slightly deformed. At the same time, the blowing hole 87 can blow air on the stacking upper box cover 6 to assist in separating the upper box cover at the top of the stacking upper box cover 6. The single upper box cover in the accommodating groove squeezes the single spring piece 84 on the first table 82 under the drive of the external material picking device to cause it to be slightly deformed and then easily detaches from the spring piece adjustment component 8 to complete the unloading of the upper box cover one by one.
