Such a structural solution requires workers to lubricate it regularly, and the transmission of the power transmission mechanism will generate relatively large noise. Therefore, for the progress of the industry technology, to better ensure the power transmission function of the pallet shaping machine and improve the core technology competitiveness, this application proposes a new implementation scheme different from the power transmission mechanism of the pallet shaping machine in the prior art. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems that the existing power transmission mechanism requires workers to lubricate it regularly and the transmission of the power transmission mechanism will generate relatively large noise, and to propose a power transmission mechanism of a pallet shaping machine.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The power transmission mechanism of a pallet shaping machine includes a frame. Both sides of the top of the frame are rotatably inserted with linkage rods. A support frame is fixedly connected to the top of the frame. A motor is fixedly connected to the top of the support frame. The inner wall of the top of the support frame is rotatably connected with a transmission shaft. A transmission gear is key-connected to the output end of the motor and the bottom end of the transmission shaft. The two transmission gears are meshed with each other. A synchronous pulley is key-connected to the top end of the linkage rod, the output end of the motor and the bottom end of the transmission shaft. A synchronous belt is connected in transmission between every two synchronous pulleys. Two support seats are fixedly connected between the inner walls on both sides of the frame. A bearing seat is arranged on the bottom inner wall of the support seat. A tension pulley is rotatably connected to the top of the bearing seat. The synchronous belt is wound around the tension pulley.

[0007] Further, a support rail is fixedly connected to the bottom inner wall of the support seat. A sliding block is slidably connected in the support rail. The top of the sliding block is fixedly connected to the bottom of the bearing seat.

[0008] Further, a rotating screw rod is rotatably inserted between the inner walls at both ends of the support seat. The bearing seat is threadedly sleeved on the rotating screw rod. A worm gear is key-connected to one end of the rotating screw rod.

[0009] Further, a worm is rotatably connected to the top of the support seat. The worm is meshed with the worm gear.

[0010] Further, a fixing screw is fixedly connected to the top of the bearing seat, and a wing nut is threadedly sleeved on the top end of the fixing screw.

[0011] Further, a connecting plate is fixedly connected between the inner walls at both ends of the supporting seat. A guiding notch is provided at the top of the connecting plate, and the fixing screw slides in the guiding notch.

[0012] Further, a protective cover is fixedly connected to the top of the supporting seat, and the protective cover covers the outer sides of the worm and the worm gear.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. By replacing the chain drive with a synchronous belt drive, the noise is smaller, the operation is more stable, and the synchronous belt drive will not have the common sliding phenomenon in the belt drive. The maintenance is simple, the synchronous belt drive does not require lubrication, the maintenance cost is low, and the service life is long.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-6 , the power transmission mechanism of the tray shaping machine includes a frame 1. Link rods 2 are rotatably inserted at both sides of the top of the frame 1. A support frame 3 is fixed to the top of the frame 1 by bolts. A motor 4 is fixed to the top of the support frame 3 by bolts. A transmission shaft 5 is rotatably connected to the inner wall of the top of the support frame 3. Transmission gears 6 are key-connected to the output end of the motor 4 and the bottom end of the transmission shaft 5. The two transmission gears 6 are meshed with each other. Synchronous pulleys 7 are key-connected to the top end of the link rod 2, the output end of the motor 4, and the bottom end of the transmission shaft 5. A synchronous belt 8 is connected between every two synchronous pulleys 7. Tooth grooves are provided on the inner side of the synchronous belt 8. Two support seats 9 are fixed to the inner walls on both sides of the frame 1 by bolts. A bearing seat 10 is provided on the bottom inner wall of the support seat 9. A tensioning pulley 11 is rotatably connected to the top of the bearing seat 10. The synchronous belt 8 is wound around the tensioning pulley 11. Driven by the motor 4 and under the action of the meshing of the two transmission gears 6, the synchronous pulley 7 rotates, thereby driving the synchronous belt 8 to rotate, and further driving the link rod 2 to rotate, so as to drive the shaping assembly to rotate for shaping operations.

[0025] The bottom inner wall of the support base 9 is fixed with a support rail 13 by bolts. A sliding block 12 is slidably connected in the support rail 13. The top of the sliding block 12 is fixedly connected to the bottom of the bearing base 10. A rotating screw rod 14 is rotatably inserted between the inner walls at both ends of the support base 9. The bearing base 10 is threadedly sleeved on the rotating screw rod 14. One end of the rotating screw rod 14 is key-connected with a worm gear 15. A worm 16 is rotatably connected to the top of the support base 9. The worm 16 meshes with the worm gear 15. By turning the worm 16, the rotating screw rod 14 is driven to rotate under the action of the meshing of the worm 16 and the worm gear 15, so as to drive the sliding block 12 to move in the support rail 13, and further drive the bearing base 10 and the tension pulley 11 to move, thus adjusting the tension of the synchronous belt 8. A fixing screw rod 19 is welded to the top of the bearing base 10. A wing nut 20 is threadedly sleeved on the top end of the fixing screw rod 19. The wing nut 20 is screwed onto the fixing screw rod 19 to fix the position of the tension pulley 11. A connecting plate 17 is welded between the inner walls at both ends of the support base 9. A guiding notch 18 is provided on the top of the connecting plate 17. The fixing screw rod 19 slides in the guiding notch 18 so that the fixing screw rod 19 can move along with the bearing base 10. A protective cover 21 is fixed to the top of the support base 9 by bolts. The protective cover 21 covers the outside of the worm 16 and the worm gear 15, and the worm 16 and the worm gear 15 are protected by the protective cover 21.

[0026] The working principle of this embodiment: When in use, the shaping assembly is connected to the linkage rod 2. First, turn the worm 16. The rotating screw rod 14 is driven to rotate under the action of the meshing of the worm 16 and the worm gear 15, so as to drive the sliding block 12 to move in the support rail 13, and further drive the bearing base 10 and the tension pulley 11 to move, thus adjusting the tension of the synchronous belt 8. At the same time, the bearing base 10 drives the fixing screw rod 19 to move in the guiding notch 18. Then the wing nut 20 is screwed onto the fixing screw rod 19 to fix the position of the tension pulley 11. Then, start the motor 4. The synchronous pulley 7 is driven to rotate under the drive of the motor 4 and the action of the meshing of the two transmission gears 6, so as to drive the synchronous belt 8 to rotate, and further drive the linkage rod 2 to rotate, thus driving the shaping assembly to rotate for shaping operation.
