Description

Technical Field

[0001] This utility model relates to the field of wooden packaging box production technology, specifically to a cutting and positioning fixture for wooden packaging box panels. Background Technology

[0002] Wooden packaging boxes, also known as wooden crates, are rectangular packaging containers made of wood, bamboo, or wood-based composite materials. They are sturdy, durable, moisture-proof, and shock-resistant, and are widely used for the transportation packaging of machinery, electronic products, precision instruments, and other products. In the production and processing of wooden packaging boxes, wood board cutting is a crucial preliminary process, as its cutting accuracy and efficiency directly determine the quality and production progress of the subsequent packaging box assembly.

[0003] Chinese Patent Publication No. CN 222060592 U discloses a wood board cutting device. This solution uses a fixing component to fix the wood board. The device places the wood board on the surface of a push plate, and a threaded shaft rotates inside the mating plate. This controls the movement of a movable sleeve on the surface of the threaded shaft. The movement of the movable sleeve can drive the pressure plate to move downward. During the movement of the pressure plate, the wood board can be pressed down, ensuring the stability of the wood board placed on the push plate surface. This reduces the probability of the wood board moving under force when it comes into contact with the cutting toothed disc for cutting, and further ensures the accuracy of cutting.

[0004] However, the following defects still exist in the actual implementation process: when fixing the wooden board, the position of the wooden board cannot be actively adjusted. Each cut requires manual adjustment, which is not only time-consuming and laborious, but also easily affects the consistency of batch cutting.

[0005] Based on this, this utility model designs a cutting and positioning fixture for wooden packaging boxes to solve the above problems. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] In some embodiments, please refer to the appendix to the instruction manual. Figure 1 - Figure 4 A cutting and positioning fixture for wooden packaging boxes includes a base plate 1. A cutting mechanism 2 is fixedly connected to the upper end of the base plate 1. A chain conveying structure 3 is provided inside the cutting mechanism 2. The chain conveying structure 3 includes a chain, a chain and a drive motor. Multiple blocking strips 4 are fixedly connected inside the cutting mechanism 2. A positioning mechanism 5 is fixedly connected inside the chain conveying structure 3. The positioning mechanism 5 includes a wooden box panel 51. A fixing component 52 is provided at the lower end of the wooden box panel 51. A tensioning component 53 is fixedly connected to the lower part of the fixing component 52.

[0017] The drive motor of the chain conveyor structure 3 is a YE4-100L1-4 three-phase asynchronous motor, which can provide power to the chain conveyor structure 3 and drive the sprocket to rotate so that the chain can circulate.

[0018] The shielding strip 4 is made of PVC material, which has a certain degree of flexibility and wear resistance. It is fixed to the inside of the side plate 21 by bolts, which can effectively prevent wood chips generated during the cutting process from clogging the chain conveyor structure 3.

[0019] The fixing component 52 includes a placement platform 521. Multiple rollers 522 are fixedly connected to the lower end of the placement platform 521. Multiple limit blocks 523 are fixedly connected to the upper end of the placement platform 521. Multiple connecting frames 524 are fixedly connected to the upper end of the placement platform 521. A cylinder 525 is rotatably connected inside each of the multiple connecting frames 524. A connecting rod 526 is fixedly connected to the output end of the cylinder 525. A rubber hammer 527 is fixedly connected inside the connecting rod 526.

[0020] The cylinder 525 is an ACQ20×25-SB compact cylinder, which can drive the rubber hammer 527 to press and fix the wooden box board 51 vertically.

[0021] The tensioning assembly 53 includes multiple connecting pins 531, which are fixedly installed inside the chain. Two connecting bars 532 are fixedly connected to the outer surfaces of the multiple connecting pins 531. A support plate 533 is fixedly connected to one end of the two connecting bars 532 that are close to each other. A connecting block 534 is fixedly connected to the upper end of the support plate 533. A placement platform 521 is fixedly installed on the upper end of the connecting block 534. A hydraulic cylinder 535 is fixedly connected to the inner cavity of the connecting block 534. A pull-back plate 536 is fixedly connected to the output end of the hydraulic cylinder 535. A rubber pad 537 is fixedly connected to one side of the pull-back plate 536.

[0022] The hydraulic cylinder 535 is a CMC06-15 single-acting hydraulic cylinder, which drives the pull-back plate 536 to tighten and position the wooden box board 51, and works with the component 24 to ensure that the wooden board and the cutting component 23 are precisely aligned.

[0023] In this embodiment of the utility model, by activating the hydraulic cylinder 535, its piston rod is controlled to retract, driving the pull-back plate 536 to move towards the wooden box board 51. When the silicone rubber pad 537 on one side of the pull-back plate 536 is tightly attached to one side of the wooden box board 51, the continuous pulling force provided by the hydraulic cylinder 535 can further eliminate the gap between the wooden box board 51 and the limiting block 523, ensuring that the wooden box board 51 abuts against the limiting block 523 at the upper end of the placement platform 521. Then, the cylinder 525 is activated, causing its piston rod to extend upward, driving the connecting rod 526 to rotate downward around the rotation connection point of the connecting frame 524. At this time, the rubber hammer 527 at the end of the connecting rod 526 moves downward accordingly, finally pressing tightly against the upper surface of the wooden box board 51. Through the stable pressure output by the cylinder 525, the wooden box board 51 is firmly fixed in the vertical direction, preventing the wooden box board 51 from tilting upward during the cutting process.

[0024] By starting the drive motor of the chain conveyor structure 3, the chain is driven to circulate through the meshing transmission between the chain and the driven gear. Since the connecting pin 531 of the tensioning component 53 is fixedly installed inside the chain, the movement of the chain will drive the connecting pin 531, connecting bar 532, support plate 533, connecting block 534 and the placement table 521 to move as a whole. The roller 522 at the lower end of the placement table 521 will also roll along the rolling groove 22, reducing the frictional resistance when the placement table 521 moves, so that the placement table 521 drives the wooden box board 51 to move smoothly towards the cutting component 23. When the saw blade 2365 contacts the edge of the wooden box board 51, the cutting operation of the edge of the wooden box board 51 begins.

[0025] In some embodiments, such as Figure 5 - Figure 9 As shown, in a preferred embodiment of the present invention, the cutting mechanism 2 includes two side plates 21, both side plates 21 are fixedly installed on the upper end of the base plate 1, both side plates 21 are provided with rolling grooves 22, both sides of the two side plates 21 are fixedly connected to the cutting components 23, and both sides of the two side plates 21 are fixedly connected to the alignment components 24.

[0026] In addition to providing support, the side plate 21 has a rolling groove 22 at its upper end that provides a moving track for the roller 522 at the lower end of the placement platform 521, ensuring that the placement platform 521 moves stably along a fixed track under the drive of the chain conveyor structure 3 and avoids deviation.

[0027] The cutting assembly 23 includes two connecting seats 231, which are fixedly installed on the outer sides of the two side plates 21 respectively. One of the connecting seats 231 is fixedly connected to a motor 232 on one side. The output end of the motor 232 is fixedly connected to a bidirectional lead screw 233 through a coupling. The two threads on the outer surface of the bidirectional lead screw 233 are the same but opposite in direction. A reinforcing seat 234 is rotatably connected to the outer surface of the bidirectional lead screw 233. The reinforcing seat 234 is fixedly installed on the inner side of the two side plates 21. Two slide rails 235 are fixedly connected to the ends of the two connecting seats 231 that are close to each other. The slide rails 235 are fixedly installed on the outer side of the side plate 21. Two cutting pieces 236 are threadedly connected to the outer surface of the bidirectional lead screw 233.

[0028] Motor 232 is a YE3-90S-4 three-phase asynchronous motor, which serves as the power source for the bidirectional lead screw 233 in the cutting assembly 23. It drives the lead screw to rotate forward and backward to achieve synchronous movement of the two cutting pieces 236 in opposite directions, facilitating the adjustment of the cutting width. The cutting component 236 includes a moving block 2361, which is threaded to the outer surface of a two-way lead screw 233. Slider 2362s are fixedly connected to both sides of the moving block 2361. The inner surfaces of the two sliders 2362s are slidably connected to the outer surfaces of the two slide rails 235, respectively. A motor 2364 is fixedly connected to the upper end of the moving block 2361. The output end of the motor 2364 is fixedly connected to a pulley drive structure 2363 through a coupling. The pulley drive structure 2363 includes a drive wheel, a synchronous belt, and a transmission wheel. The output end of the motor 2364 is fixedly connected to the drive wheel. A saw blade 2365 is fixedly installed on the inner wall of the transmission wheel. The saw blade 2365 is fixedly connected inside the pulley drive structure 2363.

[0029] Motor 2364 adopts a Y2VP-112M-2 variable frequency speed control three-phase asynchronous motor to provide high-speed rotation power for the saw blade 2365 of the cutting part 236. The torque is transmitted to the saw blade 2365 through the pulley drive structure 2363 to achieve cutting.

[0030] The alignment assembly 24 includes two connecting seats 241, which are fixedly installed on the outer sides of the two side plates 21 respectively. One of the connecting seats 241 is fixedly connected to a motor 242 on one side. The output end of the motor 242 is fixedly connected to a double-acting screw 243 via a coupling. The two threads on the outer surface of the double-acting screw 243 are the same but opposite in direction. A reinforcing seat 244 is rotatably connected to the outer surface of the double-acting screw 243. The reinforcing seat 244 is fixedly installed on the inner side of the two side plates 21. Two slide rails 245 are fixedly connected to the ends of the two connecting seats 241 that are close to each other. The slide rails 245 are fixedly installed on the outer side of the side plates 21. Two alignment parts 246 are threadedly connected to the outer surface of the double-acting screw 243.

[0031] Motor 3 242 adopts YE3-80M1-4 three-phase asynchronous motor, which can drive the bidirectional lead screw 243 of the alignment component 24 to rotate, and drive the two alignment parts 246 to move synchronously to adjust the position of the wooden box board 51 so that it can be aligned with the cutting component 23, which facilitates the completion of double-sided cutting.

[0032] The alignment component 246 includes a second movable block 2461, which is threaded to the outer surface of the second bidirectional lead screw 243. Slider 2462 is fixedly connected to both sides of the second movable block 2461. The inner surfaces of the two sliders 2462 are slidably connected to the outer surfaces of the two slide rails 245 respectively. A connecting plate 2463 is fixedly connected to the upper end of the second movable block 2461. A push plate 2464 is fixedly connected inside the connecting plate 2463. A rubber pad 2465 is fixedly connected to one side of the push plate 2464.

[0033] In this embodiment of the invention, by controlling the motor 242 to operate, its output end drives the bidirectional lead screw 243 to rotate via a coupling. Since the two sections of the thread on the outer surface of the bidirectional lead screw 243 have opposite directions and are threadedly connected to the moving block 2461, and the sliders 2462 on both sides of the moving block 2461 slide against the slide rail 245, restricting the rotation of the moving block 2461, the two moving blocks 2461 will drive the alignment member 246 to move synchronously towards each other; alignment... As the push plate 2464 of component 246 moves with the second moving block 2461, the silicone rubber pad 2465 on one side of the push plate 2464 gradually comes into contact with both sides of the wooden box board 51. By continuously applying lateral pushing force, the lateral position of the wooden box board 51 on the placement table 521 is adjusted until the two push plates 2464 are respectively attached to both sides of the wooden box board 51. At this time, the center line of the wooden box board 51 coincides with the cutting center line of the cutting component 23, realizing the center alignment of the wooden box board 51 and the cutting component 23, and the alignment process is completed.

[0034] By energizing motor 232, its output end drives the bidirectional lead screw 233 to rotate via a coupling. The two reverse threads on the outer surface of the bidirectional lead screw 233 drive the two moving blocks 2361 to move synchronously in opposite directions. The sliders 2362 on both sides of the moving blocks 2361 slide on the slide rail 235, ensuring that the moving blocks 2361 move accurately along a fixed trajectory, thereby adjusting the distance between the two cutting pieces 236 to match the preset cutting width. Then, motor 2364 is started, and its output end drives the drive wheel of the belt drive structure 2363 to rotate via a coupling. The drive wheel transmits power to the transmission wheel through a synchronous belt, and the transmission wheel in turn drives the saw blade 2365 to rotate at high speed.

[0035] It should be noted that the motor 242, hydraulic cylinder 535, motor 232, motor 2364, chain conveyor structure 3, and cylinder 525 in this utility model are powered by a power source and controlled by a controller.

[0036] It should be noted that the specific installation methods, circuit connection methods, oil circuit connection methods, and control methods of motor 242, hydraulic cylinder 535, motor 232, motor 2364, chain conveyor structure 3, and cylinder 525 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0037] Working principle: After placing the wooden crate 51 to be cut on the placement table 521, the alignment component 24 is activated, energizing the motor 242. Its output drives the bidirectional lead screw 243 to rotate via a coupling. Since the two threads on the outer surface of the bidirectional lead screw 243 are in opposite directions and are threadedly connected to the moving block 2461, and the sliders 2462 on both sides of the moving block 2461 slide against the slide rail 245, restricting the rotation of the moving block 2461, the two moving blocks 2461 will drive the alignment component 246. The push plate 2464 of the alignment component 246 moves with the second moving block 2461. The silicone rubber pad 2465 on one side of the push plate 2464 gradually contacts both sides of the wooden box 51. By continuously applying lateral pushing force, the lateral position of the wooden box 51 on the placement table 521 is adjusted until the two push plates 2464 are respectively attached to both sides of the wooden box 51. At this time, the center line of the wooden box 51 coincides with the cutting center line of the cutting component 23, realizing the center alignment of the wooden box 51 and the cutting component 23, and the alignment process is completed.

[0038] After alignment, the position of the wooden box panel 51 can be defined. First, the hydraulic cylinder 535 in the tensioning assembly 53 is activated, and its piston rod retracts, driving the pull-back plate 536 to move towards the wooden box panel 51. When the silicone rubber pad 537 on one side of the pull-back plate 536 is tightly attached to one side of the wooden box panel 51, the continuous pulling force provided by the hydraulic cylinder 535 can further eliminate the gap between the wooden box panel 51 and the limiting block 523, ensuring that the wooden box panel 51 is pressed against the limiting block 523 at the upper end of the placement platform 521. Then, the cylinder 525 is activated, causing its piston rod to extend upward, driving the connecting rod 526 to rotate downward around the rotation connection point of the connecting frame 524. At this time, the rubber pressure hammer 527 at the end of the connecting rod 526 moves downward accordingly, finally pressing tightly against the upper surface of the wooden box panel 51. Through the stable pressure output by the cylinder 525, the wooden box panel 51 is firmly fixed in the vertical direction, preventing the wooden box panel 51 from tilting upward during the cutting process.

[0039] After the positioning process is completed, the cutting component 23 can be adjusted according to the cutting size before cutting begins. The motor 232 is powered on and its output end drives the double-acting screw 233 to rotate through the coupling. The two reverse threads on the outer surface of the double-acting screw 233 drive the two moving blocks 2361 to move synchronously in opposite directions. The sliders 2362 on both sides of the moving blocks 2361 slide on the slide rail 235 to ensure that the moving blocks 2361 move accurately along the fixed trajectory, thereby adjusting the distance between the two cutting parts 236 to match the preset cutting width. Then, the motor 2364 is started, and its output end drives the drive wheel of the belt drive structure 2363 to rotate through the coupling. The drive wheel transmits power to the transmission wheel through the synchronous belt, and the transmission wheel drives the saw blade 2365 to rotate at high speed.

[0040] At this time, the sprocket of the chain conveyor structure 3 is rotated under the drive of the drive motor. Through the meshing transmission between the chain and the driven gear, the chain is driven to circulate. Since the connecting pin 531 of the tensioning component 53 is fixedly installed inside the chain, the movement of the chain will drive the connecting pin 531, connecting bar 532, support plate 533, connecting block 534 and the placement table 521 to move as a whole. The roller 522 at the lower end of the placement table 521 will also roll along the rolling groove 22, reducing the frictional resistance when the placement table 521 moves, so that the placement table 521 drives the wooden box board 51 to move smoothly towards the cutting component 23. When the saw blade 2365 contacts the edge of the wooden box board 51, the cutting operation of the edge of the wooden box board 51 begins.

[0041] Once the wooden box board 51 has completely passed through the saw blade 2365 and the edge trimming is complete, control cylinders 525 and 535 reset. The piston rod of cylinder 525 retracts downward, causing the rubber hammer 527 to leave the upper surface of the wooden box board 51. The piston rod of hydraulic cylinder 535 extends, causing the pull-back plate 536 and rubber pad 537 to detach from the side of the wooden box board 51, releasing the fixation on the wooden box board 51. The wooden box board 51 can then be removed. Control the chain conveyor structure 3 to reverse the conveying, resetting the positioning mechanism 5 so that it returns to the alignment component 24. Place the wooden box board 51 to be cut again and repeat the above process for continuous cutting.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
