Description

Technical Field

[0001] This invention relates to the field of ring chipper technology, specifically to a ring chipper for automated wood chip processing and transportation. Background Technology

[0002] Ring chippers are key pieces of equipment in the wood processing industry, used to cut wood into uniform chips. They are widely used in production lines in industries such as engineered wood products and papermaking. Their core working principle is to slice the fed wood using a high-speed rotating ring cutter head. To achieve continuous and automated production, modern ring chippers are typically integrated with automatic feeding, conveying, and screening systems to form an automated wood chip processing and transportation unit. This integrated design aims to improve overall production efficiency, reduce labor intensity, and ensure the uniformity of the produced wood chips to meet the raw material requirements of subsequent processes.

[0003] However, while existing automated ring chipper systems strive for efficient continuous production, they still suffer from several technical shortcomings that urgently need optimization. Firstly, in the core slicing unit, the ring cutter head in most machines has fixed or inconveniently adjustable blade angles, requiring machine shutdown and tedious individual adjustments using specialized tools. This makes it difficult to quickly adapt to changes in wood properties or chip sizes during production, impacting the equipment's process flexibility. Secondly, in the post-slicing screening stage, fixed screens or vibrating screens relying on independent power sources are commonly used, resulting in limited screening efficiency. Furthermore, wood chips and wood dust easily accumulate and clump on the screens, causing clogging and reducing grading effectiveness. Frequent shutdowns for cleaning are also necessary, severely restricting the continuous operation efficiency of automated production lines. In addition, the drive, slicing, and screening modules are often driven by independent motors or power sources, leading to complex system structures, high energy consumption, and insufficient coordination between mechanisms. Therefore, developing a ring chipper that enables convenient blade adjustment, efficient and clog-free screening, and optimized power coordination is of great significance for improving the overall performance of automated wood processing equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a ring-type wood chipper for automated processing and transportation of wood chips. This solves the problems of inconvenient blade adjustment, easy clogging of the screen, and poor coordination among the functional modules, which restrict the continuity and efficiency of production.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ring-type wood chipper for automated processing and transportation, comprising a discharge box, an outer shell communicating with the interior of the discharge box on one side, a chipper rotatably mounted inside the outer shell, the chipper being driven to rotate by a chipper drive mechanism mounted on the upper part of the discharge box to achieve chipping operation, finished product discharge outlet and wood chip discharge outlet respectively provided on both sides of the discharge box, and an upper screen and a lower screen respectively installed inside the discharge box, a screen vibration mechanism located between the upper screen and the lower screen inside the discharge box, and an anti-blocking mechanism installed on the outer side of the discharge box, the operation of the chipper drive mechanism in conjunction with the operation of the screen vibration mechanism and the anti-blocking mechanism, causing the screen vibration mechanism to drive the upper screen and the lower screen to vibrate, improving the screening effect, and the anti-blocking mechanism to clear the blockage position on the lower screen by blowing airflow.

An annular cutter head is disposed between the circular and annular hollow plates. A limiting shaft is rotatably disposed between the circular and annular hollow plates at the outer side of the annular cutter head. Worms are connected to both ends of the limiting shaft inside the circular and annular hollow plates. An annular body is rotatably disposed inside both the circular and annular hollow plates. An internal gear and a worm gear are respectively disposed on the inner and outer rings of the annular body. The worm gear meshes with the worm gear. Several adjusting gears corresponding to the blades on the annular cutter head are rotatably disposed at equal intervals at the inner ring of the annular body inside both the circular and annular hollow plates. The blades on the annular cutter head are connected to their corresponding adjusting gears on both sides, so that the blades rotate when the adjusting gears rotate. Each adjusting gear meshes with the internal gear.

[0007] Preferably, a hexagonal adjusting head connected to a worm gear is rotatably provided on the outer side of the annular hollow plate.

[0008] Preferably, both the upper and lower screens are inclined, with the upper screen inclined toward the finished product outlet and the lower screen inclined toward the sawdust outlet.

[0009] Preferably, a vibrating element one is provided on both sides of the inside of the discharge box below the upper screen. The vibrating element one includes a protrusion on the inner side wall of the discharge box. A spring is connected to the upper part of both ends of the protrusion.

A vibrating element two with the same structure as the vibrating element one is provided on both sides of the inside of the discharge box below the lower screen.

[0010] Preferably, the shaving drive mechanism includes a housing mounted on the upper part of the discharge box, a drive motor mounted on one side of the housing, and a main wheel connected to the output shaft of the drive motor inside the housing. The shaving drive mechanism also includes a drive transmission wheel rotatably mounted on one side of the housing, one end of which is connected to the center of one side of a circular hollow plate, so that the shaving device rotates when the drive transmission wheel rotates. The main wheel and the drive transmission wheel are connected by a drive belt.

[0011] Preferably, the screen vibration mechanism includes a rotating shaft rotatably disposed in the discharge box, and a cam is disposed on the outside of the rotating shaft so that the cam continuously strikes the upper screen and the lower screen in sequence when it rotates.

[0012] Preferably, the screen vibration mechanism further includes a driven wheel rotatably disposed on the other side of the housing and a driving wheel on the other side of the discharge box. The driving wheel is connected to the rotating shaft, the driven wheel is connected to the main wheel inside the housing, and the driving wheel and the driven wheel are connected by a transmission belt.

[0013] Preferably, the anti-blocking mechanism includes a bellows and a turntable rotatably disposed on one side of the discharge box. The end of the rotating shaft away from the drive wheel is connected to the turntable. An eccentric rod is disposed on the side of the turntable away from the rotating shaft. A grooved strip is horizontally slidably sleeved on the eccentric rod. The bottom of the grooved strip is connected to the piston rod on the bellows.

[0015] This invention provides a ring-type wood chipper for automated processing and transportation, which has the following advantages compared with the prior art: 1. This ring-type wood chipper, used for automated wood chip processing and transportation, achieves convenient and synchronous adjustment of the angles of each blade on the ring cutter head through the meshing transmission of a worm gear and worm wheel, coupled with the linkage between the ring body and the adjusting gear. This ingenious structural design ensures a stable and reliable adjustment process, eliminating the need for individual blade adjustments and significantly improving the efficiency and accuracy of blade angle adjustment, thus better adapting to the needs of different chipping processes.

[0016] 2. This automated wood chip processing and transportation ring-type chipper, by incorporating upper and lower screens within the discharge box, effectively separates the chipped material into finished products, wood chips, and wood powder, achieving automatic material grading. Simultaneously, it creatively utilizes the rotation of the drive wheel as a power source, driving the two screens to vibrate continuously via a belt and cam mechanism. This not only eliminates the need for an additional vibration motor, simplifying the structure, but also significantly improves the screening efficiency and separation effect of the screens.

[0017] 3. This automated wood chip processing and transportation ring-type chipper uses a single rotating shaft to drive an anti-clogging mechanism. The shaft drives the turntable and eccentric rod, causing the piston rod of the bellows to reciprocate, continuously blowing airflow towards the bottom of the screen. This design effectively disperses and prevents wood dust from accumulating and clogging the lower screen, ensuring the long-term unobstructed flow of the screening channel and further guaranteeing the continuity and stability of the grading and screening process.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-2 In this embodiment of the invention, a ring-type wood chipper for automated processing and transportation includes a discharge box 1. A shell 2 communicating with the interior is located on the upper part of one side of the discharge box 1. A chipper 3 is rotatably mounted inside the shell 2. The chipper 3 is driven to rotate by a chipper drive mechanism 4 installed on the upper part of the discharge box 1 to achieve chipping. Finished product discharge outlet 5 and wood chip discharge outlet 6 are respectively located on both sides of the discharge box 1. An upper screen 7 and a lower screen 8 are respectively installed inside the discharge box 1. A screen vibration mechanism 9 is located between the upper screen 7 and the lower screen 8 inside the discharge box 1. An anti-blocking mechanism 10 is installed on the outer side of the discharge box 1. The operation of the chipper drive mechanism 4 is linked to the operation of the screen vibration mechanism 9 and the anti-blocking mechanism 10, causing the screen vibration mechanism 9 to drive the upper screen 7 and the lower screen 8 to vibrate, improving the screening effect. The anti-blocking mechanism 10 clears the airflow blowing out from the blockage position on the lower screen 8.

[0022] Please see Figures 1-2 In this embodiment of the invention, both the upper screen 7 and the lower screen 8 are inclined, with the upper screen 7 inclined toward the finished product outlet 5 and the lower screen 8 inclined toward the sawdust outlet 6.

[0023] In use, the wood is gripped by a robotic arm and inserted into and contacts the annular cutter head 33. Then, the planing drive mechanism 4 drives the annular cutter head 33 to rotate, and the blades on the annular cutter head 33 plan the wood. After planing, the planed wood falls onto the upper screen 7 in the discharge box 1. The upper screen 7 filters out the wood chips and wood powder in the material, while the finished product slides out from the finished product discharge outlet 5. The wood chips and wood powder fall onto the lower screen 8, which filters out the wood powder and it falls to the bottom of the discharge box 1, while the wood chips are discharged from the wood chip discharge outlet 6.

[0024] Please see Figures 2-5In this embodiment of the invention, the slicer 3 includes a circular hollow plate 31 and an annular hollow plate 32. The circular hollow plate 31 and the annular hollow plate 32 are rotatably mounted on the inner sidewalls of both ends of the outer casing 2, and an annular cutter disc 33 is disposed between the circular hollow plate 31 and the annular hollow plate 32. A limiting shaft 34 is rotatably disposed between the circular hollow plate 31 and the annular hollow plate 32 at the outer side of the annular cutter disc 33. Worms 35 are connected to both ends of the limiting shaft 34 inside the circular hollow plate 31 and the annular hollow plate 32. An annular body 36 is rotatably arranged inside the annular body 36. The inner and outer rings of the annular body 36 are respectively provided with an internal gear 38 and a worm gear 37. The worm 35 meshes with the worm gear 37. Several adjusting gears 39, corresponding to each blade on the annular cutter disc 33, are rotatably arranged at equal intervals in the inner ring of the annular body 36 within the circular hollow plate 31 and the annular hollow plate 32. The blades on the annular cutter disc 33 are connected to the corresponding adjusting gears 39 on both sides, so that the blades rotate when the adjusting gears 39 rotate. Each adjusting gear 39 meshes with the internal gear 38.

[0025] Please see Figure 2 In this embodiment of the invention, a hexagonal adjusting head 310 connected to a worm gear 35 is rotatably provided on the outer side of the annular hollow plate 32.

[0026] In use, a hex wrench is used to turn the hexagonal adjusting head 310, which drives the worm gears 35 at both ends of the limiting shaft 34 to rotate. Since the worm gears 35 mesh with the worm wheel teeth 37 on the ring body 36, the rotation of the worm gears 35 will drive the ring body 36 to rotate. Since each adjusting gear 39 meshes with the internal gear 38 on the ring body 36, the rotation of the ring body 36 will drive each adjusting gear 39 to rotate. Each adjusting gear 39 drives the blade connected to it to rotate, thereby adjusting the angle of the blade.

[0027] Please see Figure 2 and Figure 6 In this embodiment of the invention, the shaving drive mechanism 4 includes a housing 41 installed on the upper part of the discharge box 1. A drive motor 42 is installed on one side of the housing 41. The output shaft of the drive motor 42 is located inside the housing 41 and connected to a main wheel. The shaving drive mechanism 4 also includes a drive transmission wheel 43 rotatably disposed on one side of the outer shell 2. One end of the drive transmission wheel 43 is connected to the center of one side of the circular hollow plate 31, so that when the drive transmission wheel 43 rotates, it drives the shaving device 3 to rotate. The main wheel and the drive transmission wheel 43 are connected by a drive belt 44.

[0028] In use, the drive motor 42 drives the main wheel inside the housing 41 to rotate, the main wheel causes the drive belt 44 to drive the drive transmission wheel 43 to rotate, the drive transmission wheel 43 drives the circular hollow plate 31 to rotate, and the circular hollow plate 31 drives the annular cutter head 33 to rotate.

[0029] Please see Figure 2 In this embodiment of the invention, a vibrating element 1 is provided on both sides of the inside of the discharge box 1 below the upper screen 7. The vibrating element 1 includes a protrusion 11 provided on the inner side wall of the discharge box 1. A spring 12 is connected to the upper part of both ends of the protrusion 11. The upper end of the spring 12 is connected to the bottom of the upper screen 7. A vibrating element 2 with the same structure as the vibrating element 1 is provided on both sides of the inside of the discharge box 1 below the lower screen 8.

[0030] Please see Figure 2 and Figure 6 In this embodiment of the invention, the screen vibration mechanism 9 includes a rotating shaft 91 rotatably disposed in the discharge box 1, and a cam 92 is disposed on the outside of the rotating shaft 91, so that when the cam 92 rotates, it will continuously strike the upper screen 7 and the lower screen 8 in sequence.

[0031] Please see Figure 2 and Figure 6 In this embodiment of the invention, the screen vibration mechanism 9 further includes a driven wheel 94 rotatably disposed on the other side of the housing 41 and a driving wheel 93 on the other side of the discharge box 1. The driving wheel 93 is connected to the rotating shaft 91, the driven wheel 94 is connected to the main wheel inside the housing 41, and the driving wheel 93 and the driven wheel 94 are connected by a transmission belt 95.

[0032] In use, the main wheel drives the driven wheel 94 to rotate, the driven wheel 94 causes the transmission belt 95 to drive the driving wheel 93 to rotate, and the driving wheel 93 drives the cam 92 on the rotating shaft 91 to rotate. Utilizing the elasticity of the spring 12, when the cam 92 rotates continuously, it will continuously strike the bottom of the upper screen 7 and the upper part of the lower screen 8, thereby causing the upper screen 7 and the lower screen 8 to vibrate and improve the screening efficiency of the upper screen 7 and the lower screen 8.

[0033] Please see Figure 2 and Figures 6-7 In this embodiment of the invention, the anti-blocking mechanism 10 includes a bellows 101 and a turntable 102 rotatably disposed on one side of the discharge box 1. The end of the rotating shaft 91 away from the drive wheel 93 is connected to the turntable 102. An eccentric rod 103 is disposed on the side of the turntable 102 away from the rotating shaft 91. A grooved strip 104 is horizontally slidably sleeved on the eccentric rod 103. The bottom of the grooved strip 104 is connected to the piston rod on the bellows 101. The air outlet of the bellows 101 is located inside the discharge box 1 and connected to a main pipe 105. A number of branch pipes 106 are equidistantly connected on one side of the main pipe 105 at a position below the lower screen 8. The upper part of the branch pipes 106 is densely covered with air outlets 107.

[0034] When in use, the rotating shaft 91 will also drive the rotating disk 102 to rotate. The rotating disk 102 will drive the eccentric rod 103 to make eccentric movements. The eccentric rod 103 will drive the grooved bar 104 to move longitudinally repeatedly. The grooved bar 104 will continuously pull the piston rod on the bellows 101 back and forth, thereby compressing air into the main pipe 105. Then, it will be sprayed from the air outlets 107 on each branch pipe 106 to the bottom of the lower screen 8, blowing the wood dust and preventing the wood dust from clogging the lower screen 8 and affecting its screening effect.

[0035] Please see Figure 7 In this embodiment of the invention, guide shafts 108 are provided on the upper parts of both sides of the bellows 101. The two ends of the grooved strip 104 are respectively longitudinally slidably sleeved on the two guide shafts 108. When the grooved strip 104 is displaced, it will slide on the guide shafts 108, which plays a role in limiting and guiding the displacement of the grooved strip 104.

[0036] Working principle: The wood is gripped by a robotic arm and inserted into and contacts the annular cutter head 33. Then, the drive motor 42 drives the main wheel inside the housing 41 to rotate. The main wheel causes the drive belt 44 to drive the drive transmission wheel 43 to rotate. The drive transmission wheel 43 drives the circular hollow plate 31 to rotate. The circular hollow plate 31 drives the annular cutter head 33 to rotate. The blades on the annular cutter head 33 will then plane the wood. This is existing technology and will not be described in detail. When it is necessary to adjust the angle of each blade on the annular cutter head 33, use a hex wrench to turn the hexagonal adjusting head 310, which drives the worm gears 35 at both ends of the limiting shaft 34 to rotate. Since the worm gears 35 mesh with the worm wheel teeth 37 on the annular body 36, the rotation of the worm gears 35 will drive the annular body 36 to rotate. Since each adjusting gear 39 meshes with the internal gear 38 on the annular body 36, the rotation of the annular body 36 will drive the adjustment gears 39 to rotate. Each adjusting gear 39 drives the blade connected to it to rotate, thereby adjusting the angle of the blade. After being shaving, the wood chips fall onto the upper screen 7 inside the discharge box 1. The upper screen 7 filters out the wood chips and wood powder in the material, while the finished product slides out from the finished product discharge outlet 5. The wood chips and wood powder fall onto the lower screen 8, which filters out the wood powder and it falls to the bottom of the discharge box 1, while the wood chips are discharged from the wood chip discharge outlet 6. When the drive motor 42 drives the main wheel inside the housing 41 to rotate, the main wheel will drive the driven wheel 94 to rotate. The driven wheel 94 causes the transmission belt 95 to drive the drive wheel 93 to rotate. The drive wheel 93 drives the cam 92 on the rotating shaft 91 to rotate. Utilizing the elasticity of the spring 12, when the cam 92 rotates continuously, it will continuously strike the bottom of the upper screen 7 and the upper part of the lower screen 8, thereby causing the upper screen 7 and the lower screen 8 to vibrate and improve the screening efficiency of the upper screen 7 and the lower screen 8. When the rotating shaft 91 rotates, it also drives the turntable 102 to rotate. The turntable 102 drives the eccentric rod 103 to make eccentric movements. The eccentric rod 103 drives the grooved bar 104 to move longitudinally and repeatedly. The grooved bar 104 will continuously pull the piston rod on the bellows 101 back and forth, thereby compressing air into the main pipe 105. Then, it is sprayed from the air outlets 107 on each branch pipe 106 to the bottom of the lower screen 8, blowing the wood dust and preventing the wood dust from clogging the lower screen 8 and affecting its screening effect.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
