[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0021] like Figure 1 As shown, an embodiment of this application provides a pallet feeding device, including a fixed plate 1. The fixed plate 1 is provided with a plurality of pallet lifting mechanisms 2. The pallet lifting mechanism 2 includes a base plate 21 for placing a pallet 3, a positioning component 22 for positioning the pallet 3, a guide column component 23 for guiding the base plate 21, and a lifting component 24 for driving the base plate 21 to move up and down.
[0022] like Figure 3 As shown, the lifting assembly 24 includes a motor 241 and a lead screw assembly 242. The motor 241 is installed at the bottom of the fixed plate 1. The driving end of the motor 241 is connected to the lead screw assembly 242 through a synchronous pulley transmission assembly 243. The driving end of the lead screw assembly 242 is connected to the base plate 21. The motor 241 is used to drive the lead screw assembly 242 to move the base plate 21 up and down.
[0023] Specifically, two pallet lifting mechanisms 2 are installed on the fixed plate 1. Multiple pallets 3 are stacked on the base plate 21 along the positioning component 22. The positioning component 22 positions the pallets 3 to ensure that there is no misalignment or shaking during the movement of the pallets 3. Then, the motor 241 drives the synchronous wheel transmission component 243 to rotate the nut 002 of the lead screw component 242. The rotation of the nut 002 causes the lead screw 001 to move upward. The lead screw 001 drives the base plate 21 and multiple pallets 3 to move upward along the positioning component 22 for feeding. During the movement, the guide column component 23 guides the base plate 21. The unloading mechanism unloads the pallets 3 sequentially. After all the pallets 3 on the base plate 21 have been unloaded, the motor 241 drives the lead screw component 242 to move the base plate 21 downward to the initial loading position to continue the pallet 3 loading and feeding operation.
[0024] In the above structure, the positioning component 22 positions the multiple pallets 3 on the base plate 21, ensuring that the pallets 3 will not misalign or shake during movement. Furthermore, the lifting component 24 and the guide column component 23 work together to achieve rapid feeding of the pallets 3, while simultaneously improving the stability and efficiency of feeding multiple pallets 3 from the base plate 21. This pallet feeding device not only has high positioning accuracy but also high stability, significantly improving feeding efficiency.
[0025] like Figure 3 As shown, in one embodiment, the lead screw assembly 242 of the tray feeding device includes a lead screw 001 and a nut 002. One end of the lead screw 001 is fixedly connected to the base plate 21 via a fixing block 003, and the other end of the lead screw 001 extends through the nut 002 to the underside of the fixing plate 1. The nut 002 and the lead screw 001 engage with each other via a threaded pair to form a transmission mechanism. One end of the synchronous pulley transmission assembly 243 is connected to the motor 241, and the other end of the synchronous pulley transmission assembly 243 is connected to the nut 002. When the motor 241 drives the synchronous pulley transmission assembly 243 to rotate the nut 002, the lead screw 001 is constrained by the rotation of the fixing block 003 and only performs axial linear motion, achieving high-precision tray 3 feeding. The fixing block 003 prevents the lead screw 001 from spinning under the influence of the nut 002, ensuring that the lead screw 001 and the base plate 21 do not separate. The lead screw assembly 242 and the motor 241 work together to achieve high-precision tray 3 feeding and improve feeding stability.
[0026] like Figure 3 As shown, in one embodiment, the synchronous pulley transmission assembly 243 of the pallet feeding device includes a driving pulley 004, a driven pulley 005, and a belt 006 wound around the driving pulley 004 and the driven pulley 005. The driving pulley 004 is connected to the drive end of the motor 241, and the driven pulley 005 is connected to the bottom of the fixed plate 1 through a fixing assembly 244. One end of the nut 002 is fixedly installed inside the driven pulley 005, and the other end of the nut 002 is fixedly installed inside the fixing assembly 244. The motor 241 drives the driving pulley 004 to rotate, which in turn drives the belt 006 and the driven pulley 005 to rotate. The driven pulley 005 drives the nut 002 and the connector 008 to rotate, and the fixing assembly 244 positions the driven pulley 005 and the nut 002. This synchronous pulley transmission assembly 243, in cooperation with the motor 241, facilitates the rotation of the nut 002, improving the lifting and moving efficiency of the lead screw 001 and the base plate 21.
[0027] like Figure 3As shown, in one embodiment, the fixing assembly 244 of the pallet feeding device includes a connecting seat 007 and a connecting head 008. One end of the connecting head 008 is fixedly connected to the bottom of the driven wheel 005, and the other end of the connecting head 008 is connected to the connecting seat 007 via a bearing. When the driven wheel 005 rotates, it drives the nut 002 and the connecting head 008 to rotate, and the connecting head 008 rotates within the connecting seat 007. The fixing assembly 244 improves the support strength for the driven wheel 005 and the nut 002.
[0028] like Figure 3 As shown, in one embodiment, a limiting plate 009 is provided at the end of the lead screw 001 of the pallet feeding device away from the base plate 21, and the limiting plate 009 limits the movement distance of the lead screw 001. This arrangement facilitates the limitation of the stroke of the lead screw 001.
[0029] like Figure 2 As shown, in one embodiment, the positioning component 22 of the pallet feeding device includes a plurality of positioning posts 221, which are mounted on the fixed plate 1. These positioning posts 221 are used to position the pallet 3 on the base plate 21. Two positioning posts 221 are located at the left end, two at the right end, and two at the rear end of the base plate 21, thus positioning the three ends of the base plate 21 to form a cavity for placing the pallet 3. The pallet 3 can be fed from the front end of the base plate 21. This arrangement not only improves the positioning effect of the pallet 3 but also facilitates the feeding of the pallet 3.
[0030] like Figure 2 As shown, in one embodiment, the guide post assembly 23 of the pallet feeding device includes four symmetrically arranged guide posts 231. One end of each guide post 231 is fixedly connected to the base plate 21, and the other end of each guide post 231 passes through the fixing plate 1 and is connected to the fixing plate 1 via a guide sleeve 232. This arrangement facilitates the guidance of the base plate 21, improving the stability and accuracy of the movement of the base plate 21.
[0031] like Figure 1 and Figure 2As shown, in one embodiment, the pallet lifting mechanism 2 of the pallet feeding device further includes a lower limit sensor 25 and several limiting blocks 26 for limiting the bottom plate 21. The lower limit sensor 25 and the limiting blocks 26 are mounted on the fixed plate 1 and located below the bottom plate 21. The lower limit sensor 25 is located below the bottom plate 21. When the lead screw assembly 242 drives the bottom plate 21 to move downwards beyond a specified position, the lower limit sensor 25 issues an alarm signal to promptly remind the staff to handle the situation. Two limiting blocks 26 are symmetrically arranged on the fixed plate 1. The two limiting blocks 26 are located below the bottom plate 21. The limiting blocks 26 limit the bottom plate 21 and prevent it from bumping against the fixed plate 1.
[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
