Description

Technical Field

[0001] The utility model relates to the technical field of plywood production, in particular to a log peeling machine. Background Art

[0002] In the plywood production process, the peeling machine can efficiently process logs or wood segments into continuous veneer strips. The veneer strip has a specific thickness and size and is the basic material for the production of plywood. The peeling machine can efficiently process the raw materials, improve production efficiency, and ensure the quality and stability of the plywood.

[0003] The existing Chinese patent with announcement number CN216328948U discloses a log peeling machine, including a placing table, a first motor is fixedly installed at both ends of the placing table, a threaded rod is fixedly installed on the output shaft of the first motor, and a threaded rod seat is threadedly connected to the left end of the threaded rod. The utility model starts the second motor and the third motor to rotate the rotating rod and the rotating wheel to drive the log, and the log is peeled by the slicing effect. By starting the fourth motor, the cutting rod cuts the material coming out of the cavity, and the cut material is temporarily stored through the placing plate.

[0004] Based on the above situation, the inventors believe that a large amount of wood powder is often produced when logs are peeled. Since wood powder has a high recycling value and if it is not handled in time, excessive contact between wood powder and the human body can easily cause respiratory and skin-related discomfort. At present, it is still difficult to quickly process and collect wood powder when logs are peeled. At the same time, during peeling, the logs will eventually become thin wooden sticks whose outer diameter does not meet the peeling requirements. At present, it is necessary to manually separate the transported wooden sticks and wooden boards, which makes it difficult to reduce the labor intensity and time. Utility Model Content

DETAILED DESCRIPTION

[0037] The technical solution of the utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0038] The utility model embodiment specifically provides a log peeling machine, please refer to Figure 1 , including a peeling mechanism 1, a support plate 2, a conveyor belt 3, a powder removal component 4 and a push rod mechanism 5.

[0039] The peeling mechanism 1 includes a support 11, a discharge port 12 opened on the support 11, and a peeling assembly fixed on the upper surface of the support 11. The bottom of the support 11 is fixed to the conveyor belt 3 through the support plate 2. After the log is peeled by the peeling assembly, the cardboard falls out from the discharge port 12, so that the cardboard falls out from the front end through the conveyor belt 3.

[0040] During implementation, the peeling assembly includes a first driving roller member 13, a second driving roller member 14, a push-pull assembly 15 and a scraper frame 16 which are arranged on the support 11. The first driving roller member 13 slides on the support 11 through the drive of the push-pull assembly 15, so that the first driving roller member 13 approaches and separates from the second driving roller member 14, so as to squeeze the log and drive it to rotate, and the log is rotated and then scraped into cardboard by the scraper frame 16. The bottom of the scraper frame 16 is fixed in the discharge port 12. Since the above-mentioned peeling assembly components are all existing mature components, the structure and peeling principle are not described in detail here.

[0041] Among them, the top of the powder removal component 4 is kept fixed with the discharge port 12, the wood powder generated during peeling is quickly collected by the powder removal component 4, the peeled cardboard falls onto the conveyor belt 3 through the powder removal component 4 and is output outward, and the pusher mechanism 5 is installed on the conveyor belt 3 to quickly push the peeled wood sticks from the conveyor belt 3.

The top of the chip guide pipe 41 is fixedly connected to the discharge port 12, and the collecting pipe 42 is located on the outside of the conveyor belt 3. The collecting pipe 42 is connected to the chip guide pipe 41. After the wood powder falls into the chip guide pipe 41, it is sucked and collected by the collecting pipe 42. When the log is cut, the wood powder falls into the chip guide pipe 41 by gravity and the suction of the collecting pipe 42. The cardboard falls onto the conveyor belt 3 along the guidance of the chip guide pipe 41, and the wood powder is collected by the collecting pipe 42 during the falling process.

[0043] For details, please refer to Figure 2The chip guide pipe 41 includes a vertical pipe 411 and a horizontal pipe 412. The top of the outer side of the vertical pipe 411 is fixed to the discharge port 12 so that the material falling into the discharge port 12 can be stably received by the vertical pipe 411. The inner end of the horizontal pipe 412 is fixedly connected to the vertical pipe 411, and the outer end of the horizontal pipe 412 is connected to the collecting pipe 42, so that the collecting pipe 42 can absorb and collect the wood powder in the vertical pipe 411.

[0044] Among them, a pull-up opening 413 is opened on one side of the vertical guide tube 411 close to the output end of the conveyor belt 3 to facilitate the cardboard and wooden sticks to quickly fall onto the conveyor belt 3 for transportation, avoid obstruction, and improve processing convenience.

[0045] For further information, please refer to Figure 2 The collecting pipe 42 includes a bin body 421 fixed to the outer end of the horizontal conduit 412 and a collecting box 422 inserted in the bin body 421.

[0047] An observation window 426 is embedded and fixed on the outer side of the bin body 421. The observation window 426 is located above the collecting box 422, so that the wood powder collection in the collecting box 422 can be observed through the observation window 426, and the wood powder can be poured out in time to avoid affecting the wood powder extraction efficiency.

[0048] For further information, please refer to Figure 2 and Figure 3The push stick mechanism 5 includes a detector 51 and a push stick assembly 52. ​​The detector 51 is fixed on the bottom side of the support 11. The detector 51 is a laser ranging sensor, and the detector 51 is located at the rear side of the push stick assembly 52, so that when the wooden stick is gradually transported from the rear end to the front end of the conveyor belt 3, the wooden stick with a thickness greater than that of the cardboard is first detected by the detector 51, and then the detector 51 sends the detection data to the background control system of the peeling process, so that the push stick assembly 52 starts to push the wooden stick out of the conveyor belt 3.

[0049] Among them, the push stick assembly 52 is installed on the side of the conveyor belt 3, and a push opening 6 corresponding to the pushing end direction of the push stick assembly 52 is opened on the support plate 2 and the conveyor belt 3, so that the push stick assembly 52 can push the wooden stick horizontally on the conveyor belt 3, so that the staff does not need to manually separate the wooden stick from the cardboard later, saving operating procedures.

[0050] For details, please refer to Figure 3 The push rod assembly 52 includes a push rod 53 linearly slidably installed on the conveyor belt 3 and a driving assembly 54 connected to the push rod 53. The push rod 53 pushes the wooden stick on the conveyor belt 3 outward through the drive of the driving assembly 54, so that the push rod 53 can be driven by the driving assembly 54 to slide telescopically on the conveyor belt 3 to meet the needs of pushing out and resetting the wooden stick.

[0051] Please refer to Figure 4 The outer side of the conveyor belt 3 is provided with a sliding opening 7, and a protruding slider 71 is integrally fixedly provided on the inner wall of the sliding opening 7. The push rod 53 includes a rod body 531, a guide rail 532, a push plate 533 and a groove 534. A guide rail 532 is provided on the outer side of the rod body 531, and the inner wall of the guide rail 532 is slidably matched with the slider 71. The outer side of the rod body 531 is slidably matched with the sliding opening 7, so that the rod body 531 can slide linearly along the sliding opening 7 under the guidance of the slider 71 and the guide rail 532;

[0052] The push plate 533 is fixed to the inner end of the rod body 531, and the rod body 531 pushes the log through the push plate 533. The groove 534 is opened on the bottom side of the rod body 531, and the groove 534 is provided at more than two places along the length direction of the rod body 531, so as to be connected with the driving assembly 54 through the groove 534, so that the rod body 531 can complete the telescopic sliding on the conveyor belt 3;

[0053] The driving assembly 54 includes a rotating wheel 541, a plugging rod 542, a gear box 543 and a motor 544. The plugging rod 542 is fixedly arranged on the outer periphery of the rotating wheel 541. The plugging rod 542 is arranged in two or more places in a circumferential array on the rotating wheel 541 so that the plugging rod 542 can cooperate with the groove 534. When the rotating wheel 541 rotates, the plugging rod 542 located at the top can be plugged into the groove 534, so that the rotation of the rotating wheel 541 pushes the rod body 531 to telescopically slide in the sliding opening 7.

[0054] The rotating wheel 541 is plugged into the groove 534 through the plug rod 542, the gear box 543 is fixedly mounted on the outside of the conveyor belt 3, and the output end of the gear box 543 is rotatably connected to the rotating wheel 541, and the motor 544 is fixedly mounted on the input end of the gear box 543 to drive the output end of the gear box 543 to rotate through the motor 544, so that the rotating wheel 541 can complete forward and reverse rotation, so that the rod body 531 meets the sliding requirements of pushing out the wooden stick.

[0055] It is worth noting that, since the height of the wooden stick is different from the thickness of the plate after peeling (either lower than the thickness of the plate, or higher), during implementation, the detection distance of the detector 51 can be customized according to actual conditions.

[0056] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
