Figure 1 The directions or positional relationships shown are only for the convenience of describing the present invention, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0017] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0018] In order to solve the above technical problems, Figure 1-4 As shown, the utility model designs a high-stability pallet track, including a frame 1 and a driving mechanism. The frame 1 is equipped with support rails 2 arranged opposite to each other on the left and right, and a conveyor belt 3 is provided on the inner side of each support rail 2. The driving mechanism is installed on the frame 1 and is used to drive the conveyor belt 3 to run longitudinally. Specifically, the driving mechanism includes a motor 4 and a guide wheel assembly 5. A fixed plate is provided under each support rail 2, and the motor 4 is installed on one side of the fixed plate. The output end of the motor 4 is connected to the conveyor belt 3 through the guide wheel assembly 5. The conveyor belt 3 is used to deliver the pallet to the unloading station. The inner side of the conveyor belt 3 is preferably provided with a pallet, which is used to support the conveyor belt 3 to prevent the pallet from sinking when it is conducted on the conveyor belt 3. The motor 4 can drive the conveyor belt 3 to run back and forth continuously to ensure stable and smooth transmission.

[0019] The frame 1 is provided with a blocking mechanism, which includes a transverse plate 6, a second lifting cylinder 7, a mounting seat 8, a bracket 9, and a roller 10. The transverse plate 6 is fixedly arranged below the two support rails 2, and the cylinder body of the second lifting cylinder 7 is fixedly connected to the transverse plate 6. The piston rod of the second lifting cylinder 7 is upwardly fixedly connected to the mounting seat 8. The bracket 9 is rotatably connected to the mounting seat 8. The roller 10 is arranged on the bracket 9. A torsion spring is installed on the connecting shaft between the mounting seat 8 and the bracket 9. The torsion spring can provide resistance when the bracket rotates. Before the pallet moves to the unloading station, the second lifting cylinder 7 raises the roller 10 so that the roller 10 can block the pallet in front of its moving direction. After the material is discharged, the roller can be lowered to release the pallet to complete the initial positioning. The roller 10 blocking mechanism controlled by the second lifting cylinder 7 can be flexibly raised and lowered as needed, and can flexibly fix and release the pallet. The torsion spring is mainly used to buffer the contact between the blocking mechanism and the pallet, reducing the impact and noise that may be generated by direct impact on the pallet. The elasticity of the torsion spring can ensure that the contact between the roller 10 and the pallet is smoother, avoiding wear of the pallet or roller 10 caused by hard contact.

[0020] The frame 1 is provided with a positioning mechanism, which is used to position the pallet at the unloading station. The positioning mechanism includes a support plate 11, a first lifting cylinder 12, a lifting plate 13, and a positioning rod 14. The support plate 11 is fixedly installed below the two support rails 2, and the first lifting cylinder 12 is fixedly installed below the support plate 11. The piston rod of the first lifting cylinder 12 passes upward through the support plate 11 and is fixedly connected to the lifting plate 13. A positioning rod 14 is fixedly provided on the lifting plate 13, and the positioning rod 14 cooperates with the positioning hole on the pallet. When the pallet is stopped by the blocking mechanism, the positioning mechanism runs, the lifting plate 13 is lifted so that the positioning rod 14 is inserted into the positioning hole of the pallet, and then the pallet is lifted for unloading. The pallet is positioned by the positioning mechanism to ensure the accurate position of the pallet on the unloading station, which provides a basis for subsequent automatic unloading and reduces errors and material losses.

[0021] It is further preferred in this embodiment that the lifting plate 13 is provided with four cantilevers that are symmetrical in pairs, and four positioning rods 14 are fixedly mounted on each cantilever respectively. The head of the positioning rod 14 is in the shape of a cone with a small upper part and a large lower part, which improves the accuracy and stability of the positioning mechanism and ensures that the pallet can be evenly positioned in all directions. The conical design of the head of the positioning rod 14 enables it to be more accurately inserted into the positioning hole of the pallet.

[0022] It is further preferred in this embodiment that a fixing seat 15 is provided on the top of the support rail 2, and a limiting plate 16 is installed on the top of the fixing seat 15. Two waist-shaped holes are provided on the limiting plate 16, and the waist-shaped holes are used to install adjusting bolts. The adjusting bolts are connected to the threaded holes on the fixing seat 15, and the adjusting bolts are used to fix the limiting plate 16 when tightened. The limiting plate can limit the pallet from above to ensure that the pallet is lifted to a precise position.

[0023] In this embodiment, it is further preferred that a control box 17 is further included, which is fixedly mounted on one side of the frame 1. The provision of the control box 17 realizes centralized control of the entire pallet rail system, simplifies the operation process, and improves the convenience of operation and the reliability of the system.

[0024] It is further preferred in this embodiment that an in-position sensor 18 is installed on one side of the support plate 11. The use of the in-position sensor 18 can monitor the position status of the pallet in real time, ensuring that corresponding operations can be performed in time when the pallet reaches the predetermined position, thereby improving the automation level of the system.

[0025] This pallet track not only improves the stability and positioning accuracy of pallet transportation, but also realizes efficient and intelligent pallet transportation through automated control. It is suitable for various automated production lines and has broad application prospects and market potential.

[0026] It is worth noting that the technical features such as motors, torsion springs, and cylinders involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout of these technical features can be selected according to conventional methods in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.

[0027] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
