Description

Technical Field

[0001] This utility model belongs to the technical field of wood processing equipment, and more specifically, it relates to a feeding and conveying device for wood board processing. Background Technology

[0002] Currently, the wood processing industry has a very broad market in my country. In wood processing production lines, due to the need for quality control and production requirements, after cutting wood into flat rectangular planks, the planks usually need to be fed to a testing device (such as the knot scanning and detection cutting device with patent publication number CN218462424U) for surface quality or color detection, and then processed according to the test results. The traditional method of feeding and conveying planks involves manually bending over to stack the cut planks into a material frame, then manually carrying the stacked planks and the material frame from the cutting process to one side of the testing device. After that, manually bending over to pick up and place individual planks from the material frame into the testing device for detection. The material is fed onto a conveyor. However, some existing testing devices require a large space for their testing or processing sections, so the height of the testing conveyor is often set quite high. The manual feeding method described above requires frequent bending over to stack and pick up the wood boards, which is not only time-consuming and labor-intensive, but also unsuitable for complex conveying environments where the distance between the cutting process and the testing conveyor is far or there are obstacles between them. In addition, when manually grabbing stacked wood boards, some thin wood boards are tightly attached, making it inconvenient to grab a single wood board or accidentally grabbing multiple wood blocks onto the testing conveyor at once, affecting the feeding efficiency and subsequent testing results. Overall, the problem is low feeding efficiency, high labor intensity, and low adaptability. Utility Model Content

By leveraging the height of the trolley to increase the height of the material bin, and employing a vertical stacking method along the thickness of the wood planks during the cutting process, compared to the existing method of horizontally stacking planks from bottom to top, it avoids the need for workers to frequently bend over during the stacking process, thus reducing labor intensity and improving material loading efficiency. The combination of the trolley, lifting conveyor, and limiting channel enables flexible transport of the wood planks and sequential loading onto the inspection conveyor. Compared to existing methods involving purely manual transport and the laying of long or complex conveyors, this utility model is more time-saving and labor-saving, with the conveyor occupying less space and being more applicable. Depending on the conveying environment, the material box is designed to be flippable. Combined with locking and flipping components, it can switch between vertical and horizontal stacking of wooden boards inside the material box. The cover-pushing mechanism automatically pushes the cover of the flipped material box upwards until the bottom horizontal wooden board passes through, thus automatically opening the cover. The pushing mechanism and pushing port automatically transport the horizontal wooden boards in the material box one by one to the lifting conveyor. The pressure plate and push plate are used to press down and adjust the top sides of the horizontal wooden boards and separate adjacent horizontal wooden blocks, respectively, to ensure that the horizontal wooden boards are always within the limit channel, thus automatically adjusting the horizontal wooden boards on the lifting conveyor.

[0016] This utility model uses a combination of a trolley, a tiltable material box, and a lifting conveyor to achieve flexible conveying and sequential loading of wooden boards, saving time and labor. It is suitable for complex conveying environments where the distance between the cutting process and the inspection conveyor is far or there are obstacles. It has the advantages of high loading efficiency, low labor intensity, and high adaptability. Attached Figure Description

[0028] To explain the technical content, objectives, and effects of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. It should be noted that the terms "upper" and "lower" used in the following description refer to the attached drawings. Figure 1 and Figure 6 The direction in the middle, the words "bottom" and "top" refer to the attached Figure 1and Figure 6 The direction of the center of the specific component's geometry is the same as the direction in which the lifting conveyor transports the horizontally placed wooden planks. It is also parallel to the "width direction of the feed inlet" or the width direction of the wooden planks inside the hopper (i.e., the direction of the wide side d1 of the wooden planks).

[0029] The most crucial concept of this utility model lies in the following: by combining the trolley 1 with the lifting conveyor 2, the flexible conveying and sequential loading of the wooden boards d are achieved, saving time and labor. This method is applicable to various conveying environments and avoids multiple wooden boards sticking together during loading. Furthermore, by utilizing the height of the trolley 1 to increase the height of the material box 7, the vertical stacking of the wooden boards d along their thickness is employed during the cutting process. Compared to the existing method of horizontally stacking the wooden boards d from bottom to top, this avoids the need for workers to frequently bend over when stacking the wooden boards d during the cutting process, further reducing costs. Labor intensity; by using locking components, flipping components, and setting the material box 7 to be flippable, the two stacking methods of wooden boards d in the material box 7 can be switched between vertical and horizontal stacking. Through the push cover mechanism 24 and the push material mechanism, the wooden boards d are automatically pushed one by one onto the lifting conveyor 2. Through the pressure plate 6 and the push plate 4, the wooden boards d on the lifting conveyor 2 are separated and limited one by one. In addition, the flipping component is not set on the trolley 1, which not only ensures that the trolley 1 and the material box 7 are lightweight, but also makes it easy for the trolley 1 and the material box 7 to be flexibly used for conveying other processes of wooden board d processing.

[0030] This utility model uses a combination of a trolley 1, a flip-up material box 7, and a lifting conveyor 2 to achieve flexible conveying and sequential loading of wooden boards d, saving time and labor. It is not only suitable for complex conveying environments where the distance between the cutting process and the inspection conveyor 3 is far or there are obstacles, but the trolley 1 and the material box 7 can also be used alone for conveying wooden boards d in other processes besides the cutting process. It has the advantages of high loading efficiency, low labor intensity, and high adaptability.

[0031] Please refer to Figures 1 to 10As shown, a feeding and conveying device for wood processing is used to inspect a conveyor 3. It includes a trolley 1 and a lifting conveyor 2 that is inclined upwards towards the inspection conveyor 3. The front and rear ends of the lifting conveyor 2 are horizontally arranged. Several push plates 4 are evenly connected to the conveying end of the lifting conveyor 2 along the conveying direction. A limiting channel 5 is formed between adjacent push plates 4 for placing a single horizontally placed wood board d in the middle. Pressure plates 6 are mounted on both sides of the lifting conveyor 2 for pressing down and adjusting the sides of the horizontally placed wood board d. Several vertically placed wood boards d are rotatably connected to the trolley 1. The material boxes 7 are stacked along the thickness direction of the wooden boards. The trolley 1 is equipped with a locking component for fixing the material boxes 7. The upper end face of the material box 7 is provided with a feeding port 8, and the lower end face is provided with a pushing port 9 with a length less than the width of the wooden board. A cover plate 10 is slidably inserted through the feeding port 8 along its length direction. The front end of the lifting conveyor 2 is provided with a cover pushing mechanism 24, a flipping component for pushing the material box 7 to rotate 90° so that the wooden boards d inside the box are horizontally stacked, and a pushing mechanism that passes through the pushing port 9 and pushes the bottom horizontal wooden board d inside the material box 7 through the feeding port 8 to the lifting conveyor 2.

[0032] As described above, when it is necessary to transport and load the wood planks d from the cutting process, which are located at a relatively long distance, onto the inspection conveyor 3 of the inspection device, firstly, using the trolley 1 and the material box 7, the height of the material box 7 relative to the ground is increased by utilizing the height of the trolley 1. Without bending over, the wood planks d cut in the cutting process can be placed vertically in the material box 7, and the vertically placed wood planks d are stacked along the thickness d3 direction of the wood planks. After the material box 7 is full of wood planks d, the trolley 1 is used to push the material box 7 and the wood planks d together towards the front end of the lifting conveyor 2 until the material box 7 is located between the flipping component and the pushing mechanism. Then, manually... Open the locking assembly to release its fixing effect on the material box 7. Under the pushing action of the flipping assembly, the material box 7 flips downward toward the direction of the lifting conveyor 2 until the material box 7 flips 90°. At this time, the feed port 8 of the material box 7 faces the front end of the lifting conveyor 2. The wooden boards d inside the material box 7 flips from being vertically placed and stacked along the thickness of the board to being horizontally placed and stacked up and down along the thickness of the board. The push port 9 is close to the bottom surface of the flipped material box 7. In addition, because the length of the push port 9 is less than the width of the wooden board d, the vertically placed wooden board d will not fall out of the push port 9 before the material box 7 flips downward.

[0033] Next, using the push-cover mechanism 24, the cover plate 10 is pushed upwards until the feed inlet 8 is partially opened, allowing the bottommost horizontal wooden board d in the material box 7 to pass through. Then, the pushing mechanism is activated, with its pushing end passing through the pushing port 9, pushing the bottommost horizontal wooden board d in the material box 7 through the feed inlet 8 to the front end of the lifting conveyor 2. The pushing end of the pushing mechanism returns to its original position, and under gravity, the second-to-last horizontal wooden board d falls to the bottom of the material box 7. The pushing mechanism continues to repeat the pushing steps until there are no more wooden boards d in the material box 7. After the horizontal wooden board d is pushed to the lifting conveyor 2, under the action of the push plate 4, each horizontally placed... The wooden boards d are separated by corresponding limiting channels 5. The pressure plate 6 is used to press down on the top of both sides of the horizontal wooden boards d on the conveying end of the lifting conveyor 2 to prevent the horizontal wooden boards d from flipping upwards and falling outside the limiting channel 5. At the same time, when one side of the horizontal wooden board d abuts against the top of the push plate 4, the pressure plate 6 will also push the side of the wooden board d located on the top of the push plate 4 into the limiting channel 5, which plays the role of automatically adjusting the horizontal wooden boards d on the lifting conveyor 2. Finally, under the conveying action of the lifting conveyor 2, the wooden boards d are conveyed from the front end of the lifting conveyor 2 through the rear end of the lifting conveyor 2 to the detection conveyor 3, thus realizing the function of feeding the wooden boards d one by one.

[0034] Furthermore, the tilting assembly includes a base 12 and a support plate 11 on one side for pushing the material box 7 to tilt. The upper end of the support plate 11 is used to support the bottom surface of the tilted material box 7. The top of the base 12 is connected to the other side of the support plate 11. A reinforcing inclined plate 13 is connected between the bottom of the support plate 11 and the base 12. A support block 14 is installed on the side of the trolley 1 away from the lifting conveyor 2 for the bottom of the other side of the support plate 11 to be placed and located outside the tilting range of the material box 7. Positioning columns 16 are mounted on both sides of the base 12. A positioning ring 15 for the directional column to pass through is connected to the bottom of the trolley 1. The base 12 is located between the trolley 1 and the lifting conveyor 2.

[0035] As described above, during the process of using the trolley 1 to move the material box 7 toward the tilting assembly, the positioning pin 16 passes through the positioning ring 15 to align the material box 7 with the tilting assembly, ensuring that the support plate of the tilting assembly can accurately contact and push the material box 7. When the material box 7 is pushed by the trolley 1 to contact the support plate, as the trolley 1 continues to move the material box 7 toward the front end of the lifting conveyor 2, under the pushing force of the support plate, the material box 7 tilts downward 90° around the width of the wooden board d inside the box toward the lifting conveyor 2. At this time, the support plate moves from one side of the trolley 1 to above the support block 14 on the other side of the trolley 1 away from the lifting conveyor 2. The support block 14 provides bottom support for the support plate, thereby automatically pushing the material box 7 to tilt. The tilting structure is simple, requires no electricity, and does not require manual bending over to tilt, which has the advantages of low cost and low labor intensity. By strengthening the inclined plate 13, the connection stability between the support plate and the base 12 is enhanced.

[0036] Furthermore, the two sides of the material box 7 near the long side of the wooden board d inside the box are both set as wide sides a, and the two wide sides a are fixedly connected to a rotating shaft 17 whose axis is parallel to the width direction of the wooden board inside the material box 7. The trolley 1 is equipped with a heightening frame 18, and the top two ends of the heightening frame 18 are rotatably connected to the two rotating shafts 17 respectively. The two sides of the material box 7 near the wide side of the wooden board inside the box are respectively set as a first narrow side b and a second narrow side c, and both are parallel to the width direction of the feed inlet 8. A set of counterweights 19 is connected to the first narrow side b, and the counterweights 19 are located at one end near the feed inlet 8.

[0037] As described above, after the locking assembly releases its fixing effect on the material box 7, the material box 7, under the action of the counterweight 19, rotates 90° downwards around the rotating shaft 17 toward the direction of the lifting conveyor 2. This causes the first narrow side b of the material box 7 to rotate with the counterweight 19 from the vertical plane near the lifting conveyor 2 to a horizontal plane parallel to the front conveying end face of the lifting conveyor 2. The feed inlet 8 of the material box 7 rotates from facing upwards to facing the lifting conveyor 2. The combination of the flipping assembly and the counterweight 19 improves the flipping speed and accuracy, ensuring that the feed inlet 8 of the material box 7 faces the lifting conveyor 2, which further improves the overall material feeding and conveying efficiency. The heightening frame 18 is used to increase the height of the feed inlet 8 of the material box 7 relative to the ground. During the process of manually stacking the vertical wooden boards d along the thickness direction of the wooden boards into the material box 7, the workers are prevented from frequently bending over, which further reduces the labor intensity.

[0038] Furthermore, both wide sides a are provided with sliding grooves 20 for sliding along the length of the feed inlet 8 on both sides of the long side of the cover plate 10. The second narrow side c is provided with an opening 21 for one side of the wide side of the cover plate 10 to pass through. Both sides of the long side of the cover plate 10 are provided with handles 22 extending outward. A spring 23 is detachably connected between the first narrow side b and the handles 22. The cover pushing mechanism 24 is located on both sides of the flipping assembly and is used to push the handles 22 upward to open the cover plate 10 to allow a single horizontal wooden board d to pass through.

[0039] As can be seen from the above description, when the material box 7 is flipped down 90° and the cover plate 10 needs to be opened automatically, the handle 22 and the push-cover mechanism 24 are used to move the handle 22 along the length of the feed inlet 8 towards the direction close to the second narrow side c, until the feed inlet 8 opened by the cover plate 10 can allow a single horizontal wooden board d to pass through, thus realizing the function of automatically opening the cover plate 10 to discharge material; the spring 23 prevents the cover plate 10 from opening during the process of the material box 7 being flipped 90°. When it is necessary to place the vertical wooden board d into the material box 7, the spring 23 can be disassembled to facilitate the complete opening of the cover plate 10.

[0040] Furthermore, the locking assembly includes a limit rod 25 arranged in a U-shape, a set of upper limit rings 26 and a set of lower limit rings 27. A set of push rods is connected to one side of the trolley 1. The upper limit rings 26 and lower limit rings 27 are both fixedly installed on the push rods. The two horizontal ends of the limit rod 25 pass through the upper limit rings 26 and lower limit rings 27 respectively. Both sides of the second narrow side c are connected to a set of upper limit tubes 28 and a set of lower limit tubes 29 for the two horizontal ends of the limit rod 25 to pass through respectively. The upper limit rings 26 are located between the set of upper limit tubes 28, and the lower limit rings 27 are located between the set of lower limit tubes 29.

[0041] As can be seen from the above description, when it is necessary to flip the material box 7 downwards by 90°, it is only necessary to manually grasp the vertical end of the limiting rod 25 and remove the two horizontal ends of the limiting rod 25 from the upper limit ring 26 and upper limit tube 28, the lower limit ring 27 and lower limit tube 29 respectively, so as to realize the function of releasing the trolley 1 from fixing the material box 7; after the material box 7 is pushed and flipped by the flipping component, the two horizontal ends of the limiting rod 25 can be re-inserted into the upper limit ring 26 and lower limit ring 27.

[0042] Furthermore, the pushing mechanism includes a cylinder 30 and a pushing plate 31. The push rod of the cylinder 30 is fixedly connected to the pushing plate 31. The bottom of the cylinder 30 is connected to a linear guide rail 32 that drives it to move toward the flipping component. Both sides of the pushing plate 31 are provided with support parts 33 for supporting the second to last horizontally placed wooden board d in the material box 7, which extends away from the flipping component. The support parts 33 are provided with a set of rollers along the length of the wooden board d.

[0043] As described above, when the material box 7 is rotated 90° downwards along the width direction of the wooden board d inside the box, the wooden board d inside the box is rotated from a vertical position to a horizontally stacked position, and the cover plate 10 is opened to allow a single horizontally stacked wooden board d to be discharged, the motor of the linear guide rail 32 is first started. The slider of the linear guide rail 32 moves, driving the cylinder 30 to move towards the material box 7 by a preset value. Then, the cylinder 30 is started, and the push rod of the cylinder 30 extends, driving the push plate 4 and the support part 33 to move together towards the material box 7. The push plate 4 first enters the rotated material box 7 through the push port 9. Then, push the bottommost horizontal wooden board d in the material box 7 towards the feed inlet 8 until the bottommost horizontal wooden board d is pushed from the feed inlet 8 into the limiting channel 5 on the front conveying end of the lifting conveyor 2. This realizes the function of automatically pushing the horizontal wooden board d in the material box 7 onto the lifting conveyor 2. Through the roller, the friction between the upper end face of the support part 33 and the bottom end face of the second to last horizontal wooden board d in the material box 7 is reduced, avoiding damage to the wooden board d due to friction, thus ensuring the quality of the wooden board d and the discharge efficiency of the horizontal wooden board d.

[0044] Furthermore, both sides of the material box 7 are provided with several limiting blocks 35 arranged in a U-shape along the length of the feed inlet 8. The long side of the vertically placed wooden board d is inserted between the two horizontal ends of the limiting block 35. The two wide sides a are connected with upper guide posts 36 whose length is parallel to the length of the feed inlet 8. The vertical ends of the limiting blocks 35 are provided with guide holes 37 for the upper guide posts 36 to pass through. The first narrow side b is provided with through holes 38 for the limiting blocks 35 without wooden boards d to fall. The outer sides of the first narrow side b are provided with receiving frames 39 whose tops communicate with the through holes 38. The bottom of the upper guide posts 36 extends into the through holes 38. The receiving frame 39 is connected to a lower guide post 40 that is coaxial with the upper guide posts 36 on one side.

[0045] As described above, during the process of vertically placing the wooden board d into the material box 7, the limiting blocks 35 on both sides of the material box 7 are used to limit the two long sides of the vertically placed wooden board, preventing two adjacent wooden boards d from sticking too tightly and affecting the subsequent discharge efficiency of the wooden board d from the material box 7. This enables the vertically placed wooden board d to be stacked quickly along the length direction of the feed inlet 8, while also preventing hands from being pinched by adjacent wooden boards d during the stacking operation. The upper guide post 36 and guide hole 37 enable the limiting blocks 35 to slide directionally along the length direction of the feed inlet 8 and connect to the two wide side a. When the pushing mechanism pushes the already flipped material box 7 into the bottom position... When the horizontally placed wooden board d of the layer is pushed to the front conveying end of the lifting conveyor 2, the two limiting blocks 35 on both sides of the long side of the wooden board d lose the support of the wooden board d. Under the action of gravity, the two limiting blocks 35 fall into the corresponding receiving frame 39 through the through hole 38 at the bottom, providing a position for the two limiting blocks 35 of the upper wooden board d to be discharged. During the falling process, the limiting blocks 35 first slide down from the upper guide post 36 to the lower guide post 40, and then slide up and down in the guide hole 37 using the lower guide post 40, thereby ensuring that the limiting blocks 35 fall directionally to the bottom of the receiving frame 39, playing the role of automatically and accurately recovering the limiting blocks 35.

[0046] Furthermore, a rotating shaft 41 with a length parallel to the width direction of the feed inlet 8 is connected to one side of the receiving frame 39. The rotating shaft 41 is rotatably connected to the first narrow side b. A rotation drive mechanism 42 is installed on the outside of the first narrow side b to drive the rotating shaft 41 to rotate to a point where one side of the receiving frame 39 abuts against the first narrow side b. A sealing cover 43 covering the rotation drive mechanism 42 and the rotating shaft 41 is detachably connected to the outside of the first narrow side b.

[0047] As described above, when the receiving frame 39 is not needed, simply activate the rotary drive mechanism 42. The rotary drive mechanism 42 drives the rotating shaft 41 to rotate, thereby causing the receiving frame 39 to rotate towards the middle of the first narrow side b until one side of the receiving frame 39 contacts the first narrow side b. This achieves the function of folding the receiving frame 39, reducing the space occupied by the receiving frame 39, and preventing the receiving frame 39 from interfering with the flipping of the material box 7. The sealing cover 43 is used to protect the rotary drive mechanism 42 and the rotating shaft 41, and also serves to be aesthetically pleasing and facilitate the flipping of the flipping component. After the material box 7 flips 90° downwards in the width direction of the wooden board d inside the box towards the direction of the lifting conveyor 2, the rotary drive mechanism 42 is activated, causing the receiving frame 39 to rotate until the top of the receiving frame 39 communicates with the through hole 38, thus automatically opening the folded receiving frame 39.

[0048] Furthermore, it also includes a feeding plate 44 and a short baffle 45. The feeding plate 44 is mounted on one side between the rear end of the lifting conveyor 2 and the conveying end of the inspection conveyor 3, and the short baffle 45 is mounted on the other side between the upper conveying end of the inspection conveyor 3.

[0049] As described above, when the horizontally placed wooden board d is conveyed to the rear end of the lifting conveyor 2, under the pushing force of the pusher plate 4, the horizontally placed wooden board d is pushed onto the feeding plate 44. Under the action of inertia or the pushing action of the rear wooden board d, it is conveyed to the middle position of the upper conveying end of the detection conveyor 3. The short baffle 45 is used to prevent the wooden board d from being pushed to the other side of the upper conveying end of the detection conveyor 3, ensuring that the wooden board d is accurately fed to the middle position of the upper conveying end of the detection conveyor 3, thereby improving the feeding accuracy of the wooden board d. Compared with the traditional manual handling of the wooden board d on the detection device, this method solves the problem that manual handling causes fatigue of the hands due to long-term handling and stacking, which leads to the tilting of the wooden board d placed on the detection device, thus affecting the accuracy of subsequent detection.

[0050] Furthermore, long baffles 46 are installed on both sides of the lifting conveyor 2. The long baffles 46 are connected to base plates 47 for supporting the bottom of the horizontal wooden board d on both sides along the conveying direction of the lifting conveyor 2. A threaded post 48 with a nut is connected to one side of the pressure plate 6. The long baffles 46 have several threaded holes 49 for the threaded post 48 to pass through along their width. The pressure plate 6 is located on both sides of the middle conveying end of the lifting conveyor 2, and the front end is provided with an arc-shaped guide part 50 for pressing down and adjusting the inclined wooden board d into the limiting channel 5. The arc-shaped guide part 50 is inclined upward towards the front end of the lifting conveyor 2.

[0051] As described above, the long baffles 46 and bottom plates 47 on both sides of the lifting conveyor 2 are used to limit the two short sides of the horizontally placed wooden board d and to support the bottom sides of the horizontally placed wooden board d, respectively, thereby improving the stability of the lifting conveyor 2 in conveying the horizontally placed wooden board d. When it is necessary to convey wooden boards d with larger or smaller thicknesses, it is only necessary to first unscrew the nut, unscrew the threaded post 48 from the threaded hole 49, and then tighten the threaded post 48 into the threaded hole 49 at the corresponding height to adjust the distance of the pressure plate 6. The height of the wooden board d from the bottom plate 47 serves the following purpose: When the wooden board d is mistakenly pushed onto a push plate 4 at the front end of the lifting conveyor 2, under the action of gravity and inertia, the wooden board d is in an inclined state with one side in contact with the top of the push plate 4 and the other side in contact with the conveyor belt of the lifting conveyor 2, or the wooden board d is placed entirely on the top of the push plate 4. In this case, the wooden board d located on the top of the push plate 4 or one side of the wooden board d is pushed into the limiting channel 5 by the arc-shaped guide part 50, which plays the role of automatically adjusting the horizontally placed wooden board d on the lifting conveyor 2.

Pressure plates 6 are set on both sides of the lifting conveyor 2 for pressing down and adjusting the sides of the horizontally placed wooden board d. The front end of the lifting conveyor 2 is provided with a push cover mechanism 24, a flipping component and a pushing mechanism. The flipping component is used to push the material box 7 to flip 90° so that the wooden boards d inside the box are horizontally stacked. The pushing end of the pushing mechanism passes through the pushing port 9 and pushes the bottom horizontally placed wooden board d in the material box 7 through the feeding port 8 to the lifting conveyor. On machine 2; long baffles 46 are installed on both sides of the lifting conveyor 2.

Both sides of the pushing plate 31 are provided with support parts 33 for supporting the second to last horizontally placed wooden board d in the material box 7, which extends away from the flipping component. The support parts 33 are provided with a set of rollers (not shown in the figure, as in the whole text) along the length direction of the wooden board d (i.e., the direction of the long side d2 of the wooden board).

[0059] The push-cover mechanism 24 is located on both sides of the flipping assembly and is used to push the handle 22 upward to open the cover plate 10 to allow a single horizontal wooden board d to pass through. In this embodiment, the push-cover mechanism 24 can be a set of push-cover plates. The distance between the top surface of the push-cover plate 10 and the inner side of the first narrow side b of the flipped material box 7 (i.e., the height of the opening part of the feed port) is greater than the thickness d3 of the wooden board. The push-cover mechanism 24 can also be a lifting cylinder or an electric push rod. The driving end of the lifting cylinder or electric push rod (not shown in the figure, but the same throughout the text) is connected to a push block (not shown in the figure, but the same throughout the text) that pushes the handle 22 upward. It is not limited to this structure. Other push structures that can push the handle 22 upward to slide to the cover plate 10 and the feed port 8 are also acceptable.

[0060] The locking assembly includes a limit rod 25 arranged in a U-shape, a set of upper limit rings 26 and a set of lower limit rings 27. A set of push rods (not shown in the figure, the same throughout the text) is connected to one side of the trolley 1.

[0061] Example 2 differs from Example 1 in that, as Figure 5 and Figure 7 As shown, several limiting blocks 35 arranged in a U-shape along the length of the feed inlet 8 are provided on both sides of the material box 7. The long side of the vertically placed wooden board d is inserted between the two horizontal ends of the limiting block 35. The two wide side a are each connected to an upper guide post 36 with a length parallel to the length of the feed inlet 8. The vertical ends of the limiting blocks 35 are provided with guide holes 37 for the upper guide posts 36 to pass through. The first narrow side b is provided with a through hole 38 for the limiting block 35 without wooden board d to fall. The outer sides of the first narrow side b are provided with tops that communicate with the through holes 38. The receiving frame 39 has an upper guide post 36 extending into the through hole 38 at its bottom. A lower guide post 40, coaxially arranged with the upper guide post 36, is connected to one side of the receiving frame 39. Compared with embodiment one, in this embodiment, when the horizontally placed wooden board d in the material box 7 is pushed to the front end of the lifting conveyor 2, the limiting block 35 is used to avoid friction between the upper and lower adjacent wooden boards d, which would affect the discharge speed of the wooden board d in the material box 7. At the same time, during the process of placing the vertically placed wooden board d into the material box 7, the wooden board d is placed quickly, while avoiding the hand being pinched by the two adjacent wooden boards d.

[0062] Example 3 differs from Example 2 in that, as with 8 and Figure 10As shown, a rotating shaft 41 with a length parallel to the width of the feed inlet 8 is connected to one side of the receiving frame 39. The rotating shaft 41 is rotatably connected to the first narrow side b. A rotating drive mechanism 42 is installed outside the first narrow side b to drive the rotating shaft 41 to rotate until one side of the receiving frame 39 abuts against the first narrow side b. A sealing cover 43 covering the rotating drive mechanism 42 and the rotating shaft 41 is detachably connected outside the first narrow side b. In this embodiment, the rotating drive mechanism 42 is composed of a motor, a vertical bevel gear, and a horizontal bevel gear. The vertical bevel gear is coaxially fixedly connected to the rotating shaft 41, and the horizontal bevel gear is coaxially fixedly connected to the drive end of the motor. This structure is not limited to this one; any other drive structure that can drive the rotating shaft 41 to rotate the receiving frame 39 by 90° is acceptable. Compared to Embodiment 2, this embodiment has the function of folding and storing the receiving frame 39, reducing the space occupied by the receiving frame 39, and avoiding interference of the receiving frame 39 with the rotation of the material box 7.

[0063] In summary, compared with the prior art, this utility model has the advantages of high feeding efficiency, low labor intensity, and high adaptability. Its working principle is as follows: First, the trolley 1 is pushed to the cutting process. The cut wooden boards d are manually placed vertically in the material box 7, and the vertically placed wooden boards d are stacked along the thickness d3 direction of the wooden boards. After the material box 7 is full of wooden boards d, the trolley 1 is pushed to a position between the flipping component and the pushing mechanism, so that the material box 7 contacts the flipping component. Then, the locking component is manually opened to release the locking component's fixing effect on the material box 7. The trolley 1 is then pushed towards the lifting conveyor 2. Under the pushing action of the flipping component, the material box 7 flips downwards by 90° towards the direction closer to the lifting conveyor 2. Then, the pushing mechanism... The cover mechanism 24 pushes the cover plate 10 upward to the preset value; then, the pushing mechanism is started, the pushing end of the pushing mechanism passes through the pushing port 9, and pushes the bottom horizontal wooden board d in the material box 7 through the feeding port 8 to the front end of the lifting conveyor 2. Then, under the action of the pushing plate 4, the horizontal wooden boards d on the lifting conveyor 2 are separated one by one into the corresponding limiting channels 5. The pressure plate 6 is used to press down and adjust the top of both sides of the horizontal wooden board d to prevent the horizontal wooden board d from flipping upward to outside the limiting channels 5. Finally, under the conveying action of the lifting conveyor 2, the wooden board d is conveyed from the rear conveying end of the lifting conveyor 2, which is horizontally set, to the detection conveyor 3, thus realizing the function of labor-saving and flexible conveying and one-by-one feeding of the wooden board d.
