Description

Technical Field

[0001] The invention belongs to the technical field of wood board processing and relates to a precise cutting device for wooden packaging box boards. Background Art

[0002] Wooden packing boxes are wooden boxes used for packaging. There is no specific regulation on their size, which is generally determined by specific requirements. Wooden packing boxes are widely used for their strength, easy access to materials, moisture-proof and other advantages. This product is widely used in the transportation and outer packaging of products in industries such as logistics, mechanical electronics, ceramic building materials, hardware and electrical appliances, precision instruments, fragile goods and oversized items. The materials meet the quarantine requirements for export commodities.

[0003] Wooden packing boxes can generally be assembled by splicing several wooden packing box boards of different lengths. The production of wooden packing box boards needs to meet certain requirements, and the length of wooden packing box boards needs to be cut to a fixed length to meet usage requirements.

[0004] The end pieces of long boards can be recut and used as shorter boards. In addition, wooden packing boxes can generally be recycled and reused many times. The wooden packing boxes will be damaged to a certain extent, but the long boards can still be used. They can be cut into shorter boards for use at a lower cost.

[0005] After searching, it is found that a Chinese patent document discloses a wooden board cutting platform for construction [Application No.: 202120013835.6; Publication No.: CN215434071U]. This cutting platform includes: a support frame, on which a moving mechanism is installed; and a cutting mechanism, which is arranged on the moving mechanism. Although the moving mechanism and the cutting mechanism can be coordinated to automatically cut the wooden board, and the wooden board can be cut conveniently, the degree of automation is low, the cutting efficiency is low, and the cutting quality is poor.

[0006] Based on this, we propose a precise cutting device for wooden packaging crates, which can stably feed, stably clamp, intermittently convey, effectively and accurately cut to length, stably deliver, stably drill, and effectively collect wood chips generated by drilling, which is safe and environmentally friendly.

[0060] Working principle of the present invention:

[0061] According to the size of the wooden packaging box board to be processed, the width of the side baffle 49 of suitable specifications can be selected according to the position of the rotating hole, avoiding the position of the hole and the limit conveyor chain 50;

[0062] The lateral shift hand wheel 28 is turned to adjust the lateral shift position of the lower slide plate 29. The first locking bolt slides inside the lateral slot at the corresponding position, so that the cutting saw 33 corresponds to the cutting slot 26. The distance between the two cutting saws 33 is adjusted to adjust the cutting width of the wooden packaging box board. After the adjustment is completed, the first locking bolt is locked to fix the lower slide plate 29. The longitudinal shift hand wheel 31 is turned to adjust the longitudinal shift position of the upper slide plate 30. The second locking bolt slides inside the longitudinal slot at the corresponding position to adjust the distance between the cutting saw 33 and the cutting slot 26 to ensure stable cutting of the wooden packaging box board. The second locking bolt is locked;

[0063] The electric control box 1 controls the operation of each electrical component, places the wooden packaging box boards to be cut inside the board rack 37, and the lowest wooden packaging box board contacts the feeding chain 34. The other power shaft of the double-axis gearbox drives two symmetrical feeding driving wheels 41 to rotate synchronously. The feeding driving wheels 41 cooperate with the feeding chain 34 and the feeding driven wheels 36 to drive the feeding chain 34 to move, thereby outputting the wooden packaging box boards on the feeding chain 34 in sequence. The wooden packaging box boards move along the limiting plates 40, and the feeding pressing sheets 39 are used to press the wooden packaging box boards to ensure stable delivery of the wooden packaging box boards.

[0064] The output shaft of the power motor drives the double-axis gear box to rotate intermittently, and one of the power shafts of the double-axis gear box drives the cutting shaft 15 to rotate intermittently through the sprocket pair 17, thereby driving the two material-shifting plates 23 to rotate synchronously and intermittently, and the two material-shifting plates 23 drive the baffles 25 to rotate intermittently, and the two baffles 25 abut against the same wooden packaging box board, cooperate with the two conveyor belts 22, clamp the wooden packaging box board, and perform intermittent transportation, and a number of equidistantly distributed discharge pressing sheets 14 are used to press the wooden packaging box board to ensure stable delivery of the wooden packaging box board;

[0065] Used for extruding and binding wooden packaging box boards, the mounting frame 18 rotates on the adjustment plate 19 to tension the two conveyor belts 22 to convey the wooden packaging box boards;

[0066] The conveying turntable 6 cooperates with the pressing conveyor belt 7 to sequentially clamp and convey the wooden packaging box boards to the cutting mechanism 9. The output shaft of the cutting motor 32 drives the cutting saw 33 to rotate at a high speed to cut off the excess length of the board ends of the wooden packaging box boards. The cut ends and wood chips fall into the collection box 55 in the placement box 12. The cut wooden packaging box boards are continuously conveyed through the conveying turntable 6 and the pressing conveyor belt 7 and output from the upper end of the chassis 8. The cut wooden packaging box boards sequentially push the previous wooden packaging box boards from the board output rack 13 to be conveyed between the two limit rods on the limit conveyor chain 50.

[0067] The output shaft of the conveying motor drives one of the rotating shafts of the limiting conveying chain 50 to rotate intermittently, driving the conveying chain 50 to move the distance between the two limiting rods, so that the area of ​​the latter two limiting rods is just opposite to the plate output rack 13, and the conveying chain 50 drives the wooden packaging box to move to the bottom of the drilling mechanism 5, and the telescopic end of the positioning push rod 53 is pushed out, and the positioning push plate pushes the wooden packaging box inward, and the positioning push plate contacts the side baffle 49. At this time, the position of the wooden packaging box is fixed, and the output shaft of the belt motor 43 drives the rotating belt 44 to move, and the rotating belt 44 drives the sliding seat 45 to slide on the drilling frame, and the position of the drilling motor 48 is adjusted. The telescopic end of the electric push rod 46 extends out, driving the sliding plate 47 to move downward, that is, driving the drilling motor 48 to move downward, and drilling the wooden packaging box;

[0068] When drilling, wood chips are generated, and the fan sucks air, and the dust cover box 52 and the collection box 55 form a negative pressure, sucking the wood chips from the dust cover box 52 and into the collection box 55 through the connecting pipe. The top of the collection box 55 is open, and the negative pressure collects the cut wood chips and the fallen ends. The collection box 55 can be drawn out regularly for cleaning;

[0069] The punched finished wooden packaging box board falls onto the unloading crawler 4, and the side plates 51 prevent the wooden packaging box board from falling, and are transported to the subsequent steps.

[0070] In summary, the feeding mechanism 2 cooperates with the power mechanism 10 to achieve stable feeding of the wooden packaging box boards and sequentially transport them into the chassis 8;

[0071] Through the cooperation between the conveying turntable 6 and the pressing conveyor belt 7, and the cooperation between the conveying turntable 6 and the power mechanism 10, stable clamping and intermittent conveying of the wooden packaging box board are achieved to meet the cutting requirements;

[0072] Through the cooperation of the two cutting mechanisms 9, effective and accurate fixed-length cutting of wooden packaging box boards is achieved;

[0073] By pressing the conveyor belt 7 and cooperating with the board discharging frame 13, the wooden packaging box boards are stably conveyed and pushed to the material transfer mechanism 3;

[0074] The material moving mechanism 3 cooperates with the drilling mechanism 5 to stably drill holes in the wooden packaging box board, and the material moving mechanism 3 cooperates with the dust collecting mechanism to effectively collect wood chips generated by drilling, which is safe and environmentally friendly.
