[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] like Figures 1-6As shown, this utility model provides an automatic pallet supply device for palletizing equipment, including a base 1, a frame 2 fixedly mounted on the base 1, a housing 3 fixedly mounted on the frame 2, a conveyor table 4 fixedly mounted on the base 1, a lifting frame 5 movably mounted on the frame 2, and a lifting mechanism 6 fixedly mounted on the frame 2. The lifting mechanism 6 drives and connects to the lifting frame 5, and a gripping mechanism 7 is fixedly mounted on the lifting frame 5. The gripping mechanism 7 includes a first motor 8 and a gripping arm 9, with the first motor 8 driving and connecting to the gripping arm 9 via a lead screw 10. The gripping arm 9 includes a crossbeam 11 and a hook plate 12, with the crossbeam 11 fixedly mounted to the hook plate 12 via an adjusting member 13. The conveyor table 4 includes a fixed frame 14, a second motor 15, and a roller 16, with the fixed frame 14 movably mounted to the roller 16, and the second motor 15 driving and connecting to the roller 16. A guide rail 17 is fixedly mounted on the frame 2, and a guide wheel 18 is fixedly mounted on the lifting frame 5, with the guide wheel 18 and the guide rail 17 in a restrictive fit. The lifting mechanism 6 drives and connects to the lifting frame 5 via a chain 19.

[0022] Through the above technical solution, the frame 2 of this utility model is fixedly installed with a lifting mechanism 6, which drives and connects to a lifting frame 5. The lifting mechanism 6 is fixedly installed with a gripping mechanism 7. When the device is running, multiple pallets are first stacked on the conveyor table 4. When the palletizing equipment needs a pallet, the lifting mechanism 6 drives the lifting frame 5, so that the gripping mechanism 7 on the lifting frame 5 is positioned at the position of the second pallet at the bottom. The gripping mechanism 7 is activated and grips and fixes the second pallet at the bottom. The lifting mechanism 6 is activated again to lift the second pallet at the bottom and all the pallets on it. At this time, only one pallet remains on the conveyor table 4. The conveyor table 4 is activated to transport the pallet to the palletizing equipment, automatically completing the pallet supply operation, reducing manual intervention and improving work efficiency.

[0023] Example 2:

[0024] like Figures 1-6 As shown, the base 1 of this utility model serves as the basic support structure for the entire device. The frame 2 is fixedly installed on the base 1, forming the main frame of the device and providing installation and support for various components. The outer shell 3 is fixedly installed on the frame 2, serving to protect the internal mechanisms and also enhancing the overall appearance. The conveyor table 4 is fixedly installed on the base 1 for conveying and temporarily storing pallets awaiting supply. The lifting frame 5 is movably installed on the frame 2, capable of moving up and down along the frame 2. The lifting frame 5 adopts a lightweight design, reducing energy consumption during the lifting process. A lifting mechanism 6 is fixedly installed on the frame 2, and the lifting mechanism 6 is drivenly connected to the lifting frame 5. The lifting mechanism 6 is electrically driven, and a precise control system enables the smooth up and down movement of the lifting frame 5. A gripping mechanism 7 is fixedly installed on the lifting frame 5 for gripping and releasing pallets.

[0025] In practical applications, workers first stack multiple pallets on conveyor table 4. When the palletizing equipment needs a pallet, lifting mechanism 6 drives lifting frame 5 to move, positioning gripping mechanism 7 at the position of the second pallet from the bottom of the pallet stack. Gripping mechanism 7 activates and secures all pallets except the bottom one. Subsequently, lifting mechanism 6 drives lifting frame 5 to rise, lifting the secured pallets and separating the bottom pallets from the others. Conveyor table 4 then transports the bottom pallets to the palletizing equipment. After supplying the pallets, lifting mechanism 6 restarts, returning the remaining pallets to conveyor table 4 for the next use. This automated supply method significantly improves work efficiency and reduces manual intervention.

[0026] Example 3:

[0027] like Figures 1-6 As shown, the gripping mechanism 7 of this utility model includes a first motor 8 and a gripping arm 9. The first motor 8 is driven and connected to the gripping arm 9 via a lead screw 10. The gripping arm 9 is symmetrically arranged and, driven by the first motor 8 in conjunction with the lead screw 10, can open or close, thereby completing the gripping of the pallet. The first motor 8, as the power source of the gripping mechanism 7, adopts a stepper motor design, which can provide precise rotation control. The output shaft of the motor is directly connected to the lead screw 10, ensuring efficient power transmission. In actual operation, when it is necessary to grip the pallet, the control system issues a command, and the first motor 8 begins to rotate. The rotational motion of the motor is converted into linear motion through the lead screw 10, pushing the gripping arm 9 to move inward. The gripping arm 9 gradually closes until it firmly clamps the pallet. When it is necessary to release the pallet, the motor rotates in the opposite direction, and the lead screw 10 drives the gripping arm 9 to move outward, thereby releasing the pallet. By adjusting the stroke of the lead screw 10, the gripping mechanism 7 can accommodate pallets of different widths. This flexibility allows the device to handle pallets of various sizes, increasing its versatility and avoiding the hassle of frequently changing gripping devices. To further improve gripping accuracy, the gripping mechanism 7 is also equipped with position sensors. These sensors monitor the position of the gripping arm 9 in real time and feed the information back to the control system. The control system then fine-tunes the motor's operation based on this information, thereby achieving more precise gripping actions.

[0028] Example 4:

[0029] like Figures 1-6As shown, the gripping arm 9 of this utility model includes a crossbeam 11 and a hook plate 12. The hook plate 12 is fixedly mounted on the crossbeam 11 via an adjusting member 13. The hook plate 12 is used to hook onto the pallet, allowing the gripping mechanism 7 to grip the pallet. The position of the hook plate 12 on the crossbeam 11 can be adjusted via the adjusting member 13, facilitating the hook plate 12 to hook onto different types of pallets. The crossbeam 11, as the main structure of the gripping arm 9, adopts a hollow design, ensuring both strength and weight reduction. The length of the crossbeam 11 is determined according to the maximum pallet size, ensuring coverage of pallets of various specifications. Connection points are provided at both ends of the crossbeam 11 for connection with other parts of the gripping mechanism 7, ensuring the stability of the overall structure. The hook plate 12 is the part of the gripping arm 9 that directly contacts the pallet. The shape of the hook plate 12 allows it to firmly hook onto the edge of the pallet. The adjusting member 13 adopts a sliding mechanism design, allowing the hook plate 12 to slide freely on the crossbeam 11. The adjusting component 13 includes a locking device that can fix the hook plate 12 in the desired position after adjustment. This allows operators to quickly adjust the position of the hook plate 12 according to different sizes and shapes of the clamps, greatly improving the adaptability of the device.

[0030] In practical applications, when handling new types of pallets, the operator first unlocks the adjusting component 13. Then, according to the size of the new pallet, the hook plate 12 is slid to the appropriate position. After confirming the correct position, the adjusting component 13 is relocked to complete the adjustment process. This simple adjustment method does not require complicated tools, greatly reducing equipment changeover time.

[0031] Example 5:

[0032] like Figures 1-6 As shown, the conveyor table 4 of this utility model is mounted on the base 1 for conveying pallets. The conveyor table 4 consists of a fixed frame 14, a second motor 15, and rollers 16. The fixed frame 14, as the main structure of the conveyor table 4, is welded from steel and has sufficient strength to support the rollers 16 and the drive system. The fixed frame 14 is provided with multiple bearing seats for movably mounting the rollers 16. The rollers 16 are cylindrical metal shafts with a rubber layer covering the surface to increase friction. Multiple rollers 16 are arranged in parallel to form a conveying plane. The second motor 15 is mounted on one side of the fixed frame 14 and is connected to the rollers 16 via belt drive or chain drive 19. When pallets need to be conveyed, the control system starts the second motor 15, and the motor output shaft rotates, driving the transmission mechanism to rotate, which in turn drives the rollers 16 to rotate. The rotating rollers 16 generate friction with the bottom surface of the pallets, pushing the pallets forward. During the conveying process, photoelectric sensors monitor the position of the pallets. When the pallets reach the designated position, the control system stops the second motor 15, completing the conveying of a single pallet. This process is repeated to achieve continuous and automatic supply of pallets.

[0033] Example 6:

[0034] like Figures 1-6As shown, the frame 2 of this utility model serves as the main frame of the device, constructed from welded steel profiles, providing excellent rigidity and stability. A guide rail 17 is fixedly installed on the vertical portion of the frame 2. The guide rail 17 is made of high-precision steel with a hardened surface, exhibiting extremely high straightness and smoothness. The guide rail 17 extends along the entire height of the frame 2, providing full-range guidance for the lifting frame 5. The lifting frame 5 is a rectangular frame structure with multiple guide wheels 18 fixedly installed on both sides. The guide wheels 18 are made of high-strength engineering plastic, possessing excellent wear resistance and self-lubricating properties. The outer circumference of the guide wheels 18 is tightly fitted against the surface of the guide rail 17, forming a rolling contact. When the lifting mechanism 6 drives the lifting frame 5 to move, the guide wheels 18 roll along the guide rail 17, restricting the lateral movement of the lifting frame 5 and allowing it to move only in the vertical direction. This guiding method greatly reduces friction during the lifting process, making the lifting motion smoother. Meanwhile, the cooperation between the guide rail 17 and the guide wheel 18 eliminates any possible swaying or tilting of the lifting frame 5, ensuring the accuracy and stability of the lifting.

[0035] Example 7:

[0036] like Figures 1-6 As shown, the lifting mechanism 6 of this utility model is fixedly installed on the top of the frame 2, and mainly consists of a geared motor, a drive sprocket, a driven sprocket, and a chain 19. The geared motor is fixed to the frame 2 via a flange, and its output shaft is connected to the drive sprocket. The drive sprocket is installed on the top of the frame 2, and the driven sprocket is installed on the bottom of the frame 2. The two are connected by the chain 19 to form a closed-loop transmission system. One side of the chain 19 is fixedly connected to the lifting frame 5, and the movement of the chain 19 drives the lifting frame 5 to move up and down. When the geared motor starts, it drives the chain 19 to move through the drive sprocket, thereby driving the lifting frame 5 to rise or fall. The tension of the chain 19 transmission system is achieved by adjusting the position of the driven sprocket to ensure that no slack occurs during transmission.
