[0026] The first sensor is located near the front section of the feeding assembly 8, and is situated beside or above the forward movement path of the sheet material. It is used to output a sheet material arrival signal to trigger the flipping action of the flip cover 9.

The lifting plate 10 is located below the sheet material running path and rises vertically under the drive of the fourth cylinder 51 to lift the sheet material to a predetermined height when the flip cover 9 presses down on the sheet material, thereby completing the peeling.

[0029] The principle of this utility model is as follows: This utility model, a flip-top lifting sheet feeder, achieves automated and precise sheet feeding through the sequential coordination and structural cooperation of various functional modules. Its core workflow follows the logical sequence of "sheet feeding from the hopper → material handling and loading → material pressing and fixing → material pulling forward → sensor triggering → flip-top lifting and peeling → ready to be grabbed," as detailed below: 1. Initial preparation and silo height compensation First, the stacked sheet material is placed on the first support plate 11 of the hopper section 2. The four first guard plates 18 form a four-way limit on the sheet material through the first guide holes 17 at the four corners of the first support plate 11 to prevent the sheet material from shifting or tipping over. The first motor 14 starts and drives the first support plate 11 to move up and down along the two first slide rails 13 through the meshing of the first gear 15 on the output shaft and the vertically set first rack 16. This achieves height compensation of the stacked sheet material and ensures that the top layer of sheet material is always within the adsorption range of the suction cup 4 of the conveying part 3, providing a stable material supply basis for subsequent suction actions.

[0030] 2. Sheet material handling and peeling station loading The conveying section 3 starts: the second motor 24 drives the first pulley 22 to rotate, which in turn drives the first belt 21, which is wrapped around the first pulley 22 and the second pulley 23, to move, thereby driving the first mounting plate 20, which is slidably mounted on the second slide rail 19, to move horizontally to the top of the hopper. The first cylinder 25 (vertically set) drives the second mounting plate 26 to move downward, so that the multiple suction cups 4 on the second mounting plate 26 contact the upper surface of the sheet and adhere and fix it. The first cylinder 25 resets and drives the second mounting plate 26 to rise. At the same time, the second motor 24 drives the first mounting plate 20 to move horizontally along the second slide rail 19 to above the peeling blade 27 at the peeling station. The first cylinder 25 then drives the second mounting plate 26 to descend again, and the suction cup 4 releases the sheet material, completing the precise handling and feeding of the sheet material from the hopper to the peeling station.

[0031] 3. The pressing mechanism fixes the tail of the sheet material. According to the current sheet length specifications, the third motor 35 starts, and drives the second belt 32 to move through the fifth pulley 36 on the output shaft (the second belt 32 is wrapped around the third pulley 33 and the fourth pulley 34, and is tensioned and guided by the first tensioning pulleys 37 on both sides), thereby driving the first support plate 29 fixed on the second belt 32 to move horizontally along the two third slide rails 28, and adjusting the horizontal position of the first pressure plate 31; When the first pressure plate 31 moves to the position corresponding to the tail of the sheet material, the second cylinder 30 is activated, and the output end drives the first pressure plate 31 to move downward, pressing the tail of the sheet material to achieve axial fixation of the sheet material and avoid displacement of the sheet material during subsequent pulling and peeling processes.

[0032] 4. The feeding assembly moves the sheet forward. When the third cylinder 42 of the feeding assembly 7 is activated, the output end pushes the first bracket 43 forward, causing the second roller 39, which is rotatably mounted on the first bracket 43, to move closer to the first roller 38 until the two rollers clamp the head of the sheet material. The fourth motor 40 starts and drives the first roller shaft 38 to rotate through the third belt 41. Using the friction between the two roller shafts and the sheet, the sheet is pulled forward along the running path of the peeling plate 27. The peeling plate 27 simultaneously forms a lateral peeling guide edge on the sheet, preparing for subsequent complete peeling.

[0033] 5. Sensor triggering and flip cover lifting work together to separate When the sheet material moves forward to the predetermined position in front of the peeling station, the first sensor, which is set beside or above the sheet material's forward movement path, senses that the sheet material has arrived and immediately outputs a signal to trigger the flip-top lifting assembly 8 to move. The fifth motor 46 starts and drives the fourth belt 48, which is wound around the sixth belt 45 (installed at one end of the first rotating shaft 44 of the flip cover 9), through the seventh belt pulley 47 on the output shaft. This drives the flip cover 9 to flip over to cover and press the middle / front section of the sheet material, thereby fixing the sheet material peeling point. Synchronous with the flip cover 9, the fourth cylinder 51 (vertically set) is activated, and its output end pushes the second support plate 50 and the L-shaped side plate 49 fixed thereon to move upward, thereby driving the lifting plate 10 located below the sheet material to rise vertically. The lifting plate 10 lifts the sheet material upwards, and together with the lateral guide edge of the peeling blade 27 and the downward pressure of the flip cover 9, a three-dimensional peeling force of "upward pressure + downward lifting + lateral guidance" is formed, which completely separates the current sheet material from the subsequent sheet material (if they are stuck together), and the separated sheet material remains flat.

[0034] 6. Material to be grabbed and cyclical feeding After the sheet material is completely peeled off, the lifting plate 10 is reset under the drive of the fourth cylinder 51, the flip cover 9 is flipped and reset under the reverse drive of the fifth motor 46, the first pressure plate 31 of the pressing mechanism 6 is raised and reset under the drive of the second cylinder 30, and the second roller 39 of the pulling assembly 7 is retracted and reset under the drive of the third cylinder 42. After being stripped, the sheet material enters the waiting-to-be-grabbed state, awaiting the grabbing mechanism of the subsequent process to pick up the material; at the same time, the first support plate 11 of the hopper section 2 performs height compensation again according to the consumption of the sheet material, and the conveying section 3 repeats the above actions to pick up the next sheet material from the hopper and enter the next round of material supply cycle.

[0035] The entire working process is controlled by a time-series linkage triggered by sensors, realizing a fully automated closed loop of "feeding-transporting-fixing-forward movement-peeling". The driving method of each module (motor + gear rack / belt drive, cylinder drive) and the structural cooperation (slide rail guide, roller clamping, guard plate limit) ensure the accuracy, stability and efficiency of sheet material feeding.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the protection scope of the present utility model.
