[0002] The Chinese utility model patent, authorization announcement number CN 214687021 U, discloses a plywood processing positioning fixture, including a conveyor belt, a mounting frame, and a limit block. The plywood processing positioning fixture can realize the movement or disassembly of the mounting frame, which is convenient for adjustment at any time, and fixes the conveyor belt. The worm gear is driven to rotate by rotating the worm, and the threaded screw moves to the left or right when the worm gear rotates, so that the distance between the left and right pressure plates changes, and the plywood transmitted by the conveyor belt is positioned by the pressure plate.

[0003] The above solution solves the technical problems raised in the background technology, but in practical application, the above solution still has certain problems.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0028] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a plywood processing positioning fixture tooling, including a conveying mechanism 1 and a controller, the conveying mechanism 1 is fixed on the top of a frame (not shown in the figure), the conveying mechanism 1 includes a plurality of equally distributed conveyor belts 2, and also includes a side frame, a roller and a driving motor, the driving motor drives the roller to realize that the roller drives the conveyor belt 2 to rotate, when in use, the plywood is placed on the top of the conveyor belt 2, and the conveyor belt 2 is used to convey the plywood.

[0029] Gaps 3 are formed between adjacent conveyor belts 2. In this embodiment, three conveyor belts 2 are provided to form two gaps 3. A bottom positioning mechanism 4 is provided at the bottom of the conveyor belt 2 to adsorb the bottom end surface of the plywood.

[0030] like Figure 2 As shown, the bottom positioning mechanism 4 includes a hydraulic cylinder 401, a lifting frame 402 is fixed at the end of the telescopic end of the hydraulic cylinder 401, and four suction cups 403 distributed in a matrix are arranged on the top of the lifting frame 402. It can be seen that the suction cup 403 is located directly below the gap 3, and the diameter of the suction cup 403 is smaller than the width of the gap 3. A connecting pipe is fixedly connected to the bottom of the suction cup 403, and the connecting pipe is fixed to the lifting frame 402. The connecting pipe is connected to an air pump arranged on one side of the conveying mechanism 1. The air pump is an ordinary negative pressure pump or vacuum pump commonly used on the market. After starting the air pump, the suction cup 403 can adsorb the plywood.

[0031] A top positioning mechanism 5 is provided on the top of the conveyor belt 2 , and the top positioning mechanism 5 is used to press the top of the plywood, so that the plywood is stably fixed between the bottom positioning mechanism 4 and the top positioning mechanism 5 .

[0032] like Figure 3 As shown, the top positioning mechanism 5 includes a single-head electric telescopic rod, which is fixed between the conveyor belts 2 through a support seat 502. The telescopic rod of the single-head electric telescopic rod is movably plugged into the side frame of the conveyor mechanism 1, and the telescopic rod of the single-head electric telescopic rod extends out of the side frame. Two stands 503 are fixed to the top of the side frame on one side of the conveyor mechanism 1. The stands 503 are movably connected to an upwardly inclined movable frame 504 through a connecting shaft 1. A downwardly inclined support frame 505 is fixed to the end of the movable frame 504. The angle formed between the movable frame 504 and the support frame 505 is 100-150°. A top pressure roller 506 made of rubber material is movably connected to the bottom of the support frame 505 through a connecting shaft 2. In this way, since the top pressure roller 506 has a certain elasticity, when the top pressure roller 506 squeezes the top of the plywood, it can effectively prevent the top of the plywood from being damaged.

[0033] A hinge seat is fixed at the bottom of the movable frame 504 and the end of the telescopic rod of the single-head electric telescopic rod. A hinge rod 507 is arranged between the two hinge seats. Both sides of the hinge rod 507 are movably connected to the connecting shafts of the two hinge seats respectively. Example 2

[0034] Different from the single-head electric telescopic rod in Example 1, the electric telescopic rod in this embodiment is a double-head electric telescopic rod 501. Specifically, the double-head electric telescopic rod 501 is fixed between the conveyor belts 2 through a support seat 502. The two telescopic rods of the double-head electric telescopic rod 501 are movably connected to the two side frames of the conveying mechanism 1, and the telescopic rods of the double-head electric telescopic rod 501 extend out of the side frames. The tops of the side frames on both sides of the conveying mechanism 1 are fixed with a stand 503. The stand 503 is movably connected to a movable frame 504 through a connecting shaft 1. A support frame 505 is fixed to the end of the movable frame 504. The bottom of the support frame 505 is movably connected to a top pressure roller 506 made of rubber material through a connecting shaft 2. The bottom of the movable frame 504 and the end of the telescopic rod of the double-head electric telescopic rod 501 are fixed with an articulated seat. A hinged rod 507 is arranged between the two articulated seats. The two sides of the articulated rod 507 are movably connected to the connecting shafts 3 of the two articulated seats.

[0035] The double-headed electric telescopic rod 501 and both sides are provided with top pressure rollers 506, and the purpose of such arrangement is to improve the stability of the plywood after being limited.

[0036] In addition, U-shaped frames 601 are fixed on the inner sides of the side frames on both sides of the conveying mechanism 1, and a plurality of smooth wheels 602 are arranged on the sides of the U-shaped frames 601. The smooth wheels 602 on both sides guide the plywood to prevent the plywood from deflecting during the transmission process.

[0037] To supplement this solution, during operation, the plywood is placed on the top of the conveyor belt 2, and then the driving motor of the conveyor mechanism 1 is started. When the conveyor belt 2 rotates, it drives the plywood to move to the cutting station or other processing stations. At this time, the smooth wheels 602 on both sides guide the plywood to prevent the plywood from deviating during the transmission process. When the plywood moves horizontally to the cutting station, the controller controls the driving motor to stop, and then the controller controls the hydraulic cylinder 401 and the air pump to start. The hydraulic cylinder 401 drives the suction cup 403 to move upward, and the suction cup 403 passes through the gap 3 and contacts the bottom end surface of the plywood. At this time, the suction cup 403 adsorbs the bottom end surface of the plywood.

[0038] The controller controls the double-headed electric telescopic rod 501 to extend. When the telescopic rod of the double-headed electric telescopic rod 501 extends, the movable frame 504 is pushed through the hinged rod 507, so that the movable frame 504 rotates around the connecting axis 2, thereby pressing the top pressure roller 506 downward until the top pressure roller 506 is squeezed with the top surface of the plywood, and finally the plywood is stably fixed between the bottom positioning mechanism 4 and the top positioning mechanism 5.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
