[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-5 A fork hole cutting mechanism for a blow-molded one-piece pallet includes a conveyor table 1, with a conveying mechanism and a cutting mechanism respectively arranged above the conveyor table 1.

[0018] The conveying mechanism is located below the cutting mechanism.

[0019] To improve the production efficiency of blow-molded pallets, continuous cutting of batch blow-molded pallets is performed by setting up a conveyor mechanism, such as... Figures 1-3 The conveying mechanism includes a conveying roller 2, which conveys the pallet to the area below the cutting mechanism.

[0020] The conveying mechanism also includes a conveying motor 201, a support column 202 is fixedly connected to the lower surface of the conveying platform 1, both ends of the conveying roller 2 are rotatably connected to the inner wall of the conveying platform 1, the surface of the conveying motor 201 is fixedly connected to the surface of the conveying platform 1, and the output shaft of the conveying motor 201 is fixedly connected to one end of the conveying roller 2 through a coupling.

[0021] Furthermore, the drive motor 201 drives the conveyor roller 2 to rotate, thereby moving the pallet placed above the conveyor roller.

[0022] The other end of the conveyor roller 2 is fixedly connected to a connecting pulley 203. Multiple connecting pulleys 203 are linearly arrayed along the length of the conveyor roller 2. Multiple conveyor rollers 2 are linearly arrayed along the length of the conveyor table 1. The surfaces of two adjacent connecting pulleys 203 are connected by belt drive.

[0023] Furthermore, multiple adjacent conveyor rollers 2 are connected by transmission between two connecting pulleys 203 or between two second connecting pulleys, so that multiple conveyor rollers 2 can rotate synchronously to move the pallet.

[0024] To cut off the blow molding opening of the blow-molded pallet and create forkholes for easy pallet transfer, a cutting mechanism is installed, such as... Figures 1-2 and Figures 4-5 The cutting mechanism includes a cutting blade 3, which performs the action of cutting the pallet fork hole.

[0025] The cutting mechanism also includes a mounting plate 301, a top plate 302 above the mounting plate 301, a shock-absorbing pad 303 fixedly connected to the lower surface of the mounting plate 301, guide rods 304 slidably connected to the surface of the mounting plate 301, and lifting screws 305 threadedly connected to the surface of the mounting plate 301. The two guide rods 304 and the two lifting screws 305 are symmetrically distributed with respect to the axis of the length direction of the mounting plate 301. The surface of the top plate 302 is fixedly connected to the upper end of the guide rods 304. The surface of 02 is rotatably connected to the upper end of the lifting screw 305. The surface of the lifting screw 305 is fixedly connected to the lifting bevel gear 306. The lower end of the lifting screw 305 is rotatably connected to the base 307. A dual-axis motor 308 is set below the conveyor table 1. Both ends of the dual-axis motor 308 are fixedly connected to the drive shaft 309 through couplings. One end of the drive shaft 309 is fixedly connected to the drive bevel gear 310. The surface of the drive bevel gear 310 is connected to the surface of the lifting bevel gear 306 in a transmission connection.

[0026] Furthermore, the dual-axis motor 308 drives the mounting plate 301 to move downwards via the lifting screw 305. The lower surface of the mounting plate 301 contacts the upper surface of the tray through the shock-absorbing pad 303, clamping and limiting the tray to prevent displacement during the cutting process.

[0027] A limiting plate 311 is fixedly connected to the surface of the mounting plate 301. A positioning motor 312 is fixedly connected to the surface of the limiting plate 311. A positioning screw 313 is fixedly connected to the output shaft of the positioning motor 312 through a coupling. The surface of the positioning screw 313 is rotatably connected to the surface of the limiting plate 311. A positioning clamping plate 314 is threadedly connected to the surface of the positioning screw 313. The surface of the positioning clamping plate 314 is slidably connected to the surface of the limiting plate 311 and the lower surface of the mounting plate 301, respectively. The two positioning clamping plates 314 are symmetrically distributed with the axis of the limiting plate 311 as the center.

[0028] Furthermore, the two positioning clamps 314 provided below the mounting plate 301 center and clamp the two sides of the pallet, which facilitates the cutting of the pallet blow molding opening.

[0029] A cutting cylinder 315 is fixedly connected to the upper surface of the mounting plate 301. A cutting slider 316 is fixedly connected to the output end of the cutting cylinder 315. The surface of the cutting slider 316 is slidably connected to the surface of the mounting plate 301. A cutting motor 317 is fixedly connected to the surface of the cutting slider 316. A cutting shaft 318 is fixedly connected to the output shaft of the cutting motor 317 through a coupling. One end of the cutting shaft 318 is fixedly connected to the surface of the cutting disc 3.

[0030] Furthermore, the cutting cylinder 315 drives the cutting slider 316 to slide along the surface of the mounting plate 301, thereby driving the cutting blade 3 located below the cutting slider 316 to cut the blow molding opening on the tray surface.

[0031] By setting up a conveying mechanism and a cutting mechanism, the conveying mechanism transports the pallet to the bottom of the cutting mechanism through the conveying roller 2, and the cutting mechanism cuts the blow-molded fork holes on one side of the pallet through the cutting blade 3, which solves the technical problem of low processing efficiency caused by the existing pallet production mode of single-piece independent cutting.

[0032] Working principle: Before use, place the blow-molded pallet on top of the conveyor table 1, with the blow-molding port side of the pallet facing the cutting mechanism side. The conveyor motor 201 on the surface of the conveyor table 1 drives the conveyor rollers 2 to rotate on the surface of the conveyor table 1. Multiple conveyor rollers 2 on the surface of the conveyor table 1 are connected by two adjacent connecting pulleys 203, achieving synchronous rotation of the multiple conveyor rollers 2. When the blow-molded pallet above the conveyor rollers 2 is conveyed to the area below the mounting plate 301, the limiting plate 311 on one side of the mounting plate 301 is located in front of the pallet, limiting the pallet's movement. When the pallet moves to the surface of the limiting plate 311, the conveyor motor 201 stops to prevent the pallet from exceeding the cutting range. The positioning motor 312 on the surface of the limiting plate 311 is then driven. The positioning motor 312, through the positioning screw 313, drives two positioning clamps 314 to slide along the surface of the limiting plate 311 towards the center of the pallet, positioning and clamping the pallet on both sides to facilitate fork hole cutting of the blow-molded pallet. The double positioning clamps 314 located below the conveyor table 1 are then driven... The two ends of the dual-axis motor 308 drive the drive shaft 309 to rotate via couplings. The drive bevel gear 310 on the surface of the drive shaft 309 is connected to the lifting bevel gear 306 on the surface of the lifting screw 305, driving the two lifting screws 305 to rotate synchronously. This moves the mounting plate 301 downward to press the upper surface of the tray. The lower surface of the mounting plate 301 is connected to the upper surface of the tray via a shock-absorbing pad 303. After the tray is positioned and clamped, the cutting motor 317 is driven. The output end of the cutting motor 317 drives the cutting blade 3 to rotate via the cutting shaft 318 to cut the fork hole on one side of the tray. The cutting cylinder 315 above the mounting plate 301 drives the cutting slider 316 to slide along the surface of the mounting plate 301, causing the cutting blade 3 to make a straight cut along the surface of the tray. After the cutting is completed, the positioning clamp on the tray is released, and the drive conveyor motor 201 drives the tray forward via multiple conveyor rollers 2, and moves the next tray below the cutting mechanism.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
