Description

Technical Field

[0001] The invention relates to the technical field of wood processing, in particular to a wooden blade cutting device for processing blinds. Background Art

[0002] Venetian blinds are mainly used in places such as vents or windows where airflow or light needs to pass through. By pulling the lever or rope of the blinds, the blinds can be retracted or opened and closed. At present, there are many types of blinds on the market, including metal, wood, and plastic. Among them, wooden blinds have the characteristics of natural environmental protection and good decorativeness, and are deeply loved by people.

[0003] There are many kinds of wood used for wooden blinds, such as fir, basswood and nanmu. Due to the different wood materials used, their performance and appearance also vary to a certain extent. In the process of processing wooden blinds, a whole piece of wood is usually cut into several wood pieces of a certain length by multiple sets of cutting blades arranged in parallel. Due to the characteristics of the wood itself, the toughness of wooden blades is relatively poor compared with metal and plastic blades. Especially when the length of the wooden blades formed after cutting by the cutting blades is long, it is easy to bend and deform or even tear and break during the feeding process, thereby affecting the quality of the finished wooden blades or even directly causing them to be scrapped. In addition, due to the large differences in the bending resistance of different woods, the deformation and tearing conditions of wooden blades made of different woods are also different. Summary of the invention

[0004] The purpose of the present invention is to provide a wooden blade cutting device for processing blinds, so as to solve the problem that wooden blades are prone to bending, deformation or even tearing and breaking during processing, thereby affecting the quality of the finished wooden blades and even directly causing them to be scrapped.

[0045] Beneficial effects of the present invention:

[0046] According to the difference in bending strength of different woods, the appropriate cutting length is set accordingly. When the wood chip pushes the push plate to reach the adjustment block, the electric saw is automatically triggered to vertically cut the wood chip according to the preset cutting length, thereby avoiding the defects of bending and tearing of the wood chip due to excessive length; after the wood chip is cut off, it is automatically discharged from the feeding port, and at the same time, the electric saw is reset upward under the magnetic attraction of the electromagnet, and the push plate automatically rebounds and resets to carry out the next cycle of cutting operation, which can realize continuous cutting of wood chips;

[0047] A reversible partition is set. When the wood chip reaches the cutting length, the partition rotates to the unfolded state, thereby providing lateral support for the wood chip, which is convenient for subsequent stable cutting; when the electric saw completely cuts the wood chip, the partition rotates to the folded state, thereby releasing the lateral support for the wood chip, breaking the steady state of the wood chip, and promoting the wood chip to fall into the feeding port quickly;

[0048] A cable and a pulley are arranged, so that when the wood chips push the push plate to move, the translation frame can move synchronously with the push plate, and the stroke of the translation frame is always half of the push plate, so that the translation frame is always in the center position between the electric saw and the push plate, thereby providing a balanced and stable lateral support effect for the wood chips.

[0065] See also Figure 2 and Figure 3 The wooden blade cutting device for processing blinds also includes a first guide rod 8, a push plate 9, a first spring 10, a fixing frame 11, a counterweight platform 13, a locking assembly 16, an adjustment frame 17, an adjustment block 18, a feeding assembly, a traction rope 20 and a controller 37; the first guide rod 8 is provided with two groups and is symmetrically distributed on both sides of the feed opening 7; both sides of the push plate 9 are slidably sleeved on the corresponding first guide rod 8; the first spring 10 is provided on the first guide rod 8 and is located on the side of the push plate 9 away from the array cutting blade 2; the fixing frame 11 is provided on the base 1 and is located on one side of the feed opening 7, and the fixing frame 11 is vertically arranged A slide rail 12 is provided; a counterweight platform 13 is vertically slidably embedded in the slide rail 12, an electric saw 14 is installed on the side of the counterweight platform 13 facing the feed port 7, and a through slot 15 for vertical movement of the electric saw 14 is vertically opened on the fixed frame 11; a locking assembly 16 is provided on the fixed frame 11 to limit the downward path of the counterweight platform 13; an adjustment frame 17 is horizontally fixed on the base 1; an adjustment block 18 is slidably provided on the adjustment frame 17; a feeding assembly is used to drive the adjustment block 18 to move horizontally along the adjustment frame 17; one end of a traction rope 20 is connected to the locking assembly 16, and the other end is connected to the adjustment block 18;

[0066] The controller 37 is disposed on the base 1 and is used for:

[0067] First, the input bending resistance grade corresponding to the wood chip 6 is obtained, then the preset cutting length L0 corresponding to the input bending resistance grade is obtained, and then the current horizontal distance L1 between the adjustment block 18 and the electric saw 14 is obtained, and finally the current horizontal distance L1 is compared with the preset cutting length L0; when the current horizontal distance L1 is greater than the preset cutting length L0, the controller 37 controls the feeding assembly to drive the adjustment block 18 to move along the adjustment frame 17 toward the side close to the electric saw 14; when the current horizontal distance L1 is less than the preset cutting length L0, the controller 37 controls the feeding assembly to drive the adjustment block 18 to move along the adjustment frame 17 toward the side away from the electric saw 14;

[0068] Specifically, the wooden board is placed flat on the base 1, and the wooden board is pressed by the push roller 4. The push motor 5 drives the push roller 4 to rotate, so that the wooden board is fed toward one side of the array cutting blade 2. The cutting motor 3 drives each group of saw blades in the array cutting blade 2 to rotate simultaneously, so as to cut the wooden board into multiple groups of parallel wood chips 6.

[0069] According to the bending resistance level of the wood material to be processed, a corresponding cutting length is preset, and the controller 37 controls the feed assembly to drive the adjustment block 18 to move to the corresponding position on the adjustment frame 17, so that the distance between the adjustment block 18 and the electric saw 14 is just equal to the cutting length;

[0070] When the push roller 4 drives the wooden board to feed, the end of the wood chip 6 pushes the push plate 9 to move toward the side of the adjusting block 18. When the push plate 9 reaches the adjusting block 18, the locking assembly 16 is triggered by the traction rope 20 to release the lock of the counterweight platform 13, so that the counterweight platform 13 moves downward along the slide rail 12, and drives the electric saw 14 to synchronously descend to cut the wood chip 6.

[0071] It should be noted that the specific mapping relationship between the bending resistance grade and the cutting length of the wooden board can be set according to the actual application, and the two maintain a proportional relationship. The greater the bending resistance grade of the wooden board, the greater the corresponding cutting length; wherein, the bending resistance grade of the wooden board may include three grades, I, II and III, and each grade corresponds to a certain bending strength range. Specifically, bending strength ≤54.0MPa is recorded as bending resistance grade I, 54.0MPa<bending strength<88.0MPa is recorded as bending resistance grade II, and bending strength ≥88.0MPa is recorded as bending resistance grade III; under the condition of consistent shrinkage, the bending strength of the wooden board is mainly related to the material of the wooden board; different woods can be divided into corresponding bending resistance grades according to the ranking of the bending performance of the wooden boards. ; For example, the bending resistance grade of balsa wood and peach wood is grade I, the bending resistance grade of fir and basswood is grade II, and the bending resistance grade of nanmu and ironwood is grade III; the cutting length of the corresponding wood can be set according to different bending resistance grades to avoid bending and breaking of the wood chip 6 due to excessive length. For example, the cutting length of wood with bending resistance grade I is set to 3m, the cutting length of wood with bending resistance grade II is set to 5m, and the cutting length of wood with bending resistance grade III is set to 8m; of course, the cutting length should also take into account the length of a single wood chip of the finished product to be processed later, and it is best to be an integer multiple of the length of a single wood chip of the finished product, so as to avoid the loss of part of the wood. For example, if the length of a single wood chip of the finished product is 0.5m, the cutting length can be set to an integer multiple of 0.5m.

[0072] It should be further explained that, considering that the hardness of different woods is different, if the existing method is adopted to control the cutting rate of the electric saw 14 through an additional mechanism, such as driving the electric saw 14 to move vertically downward at a constant cutting rate during cutting by a cylinder or a motor, due to the large difference in hardness of different woods, when encountering wood with a higher hardness, it is easy to cause the electric saw 14 and the wood to get stuck due to the excessive cutting rate, and even cause the electric saw 14 to be scrapped or the wood section to be damaged; when encountering wood with a lower hardness, the constant cutting rate will affect the cutting efficiency of the wood;

[0073] The present invention provides a counterweight platform 13, which enables the electric saw 14 to fall down by itself while the electric saw 14 is cutting the wood chips 6. The falling rate is related to the actual working condition of the electric saw 14 cutting the wood chips 6. The electric saw 14 cuts the wood chips 6 and pushes out the wood chips generated by the cutting from one side, so that a cutting groove is formed below the electric saw 14. When the wood chips in the cutting groove are pushed out by the electric saw 14, a certain space is formed below the electric saw 14 for the electric saw 14 to move down. Then, the electric saw 14 moves down under the gravity of the counterweight platform 13, so as to continue to cut the wood chips 6 below. In this way, continuous cutting of the wood chips 6 can be achieved.

[0074] When encountering wood with greater hardness, the electric saw 14 cuts less depth per unit time, so that the overall falling speed of the electric saw 14 is also slowed down; when encountering wood with less hardness, the electric saw 14 cuts more depth per unit time, so that the overall falling speed of the electric saw 14 is also increased; that is, the overall cutting speed of the electric saw 14 can be adaptively adjusted according to the actual hardness of the wood being cut, which is more flexible to use than the traditional method of controlling a constant cutting speed through an external mechanism, and will not cause damage to the electric saw 14;

[0075] In addition, since the electric saw 14 is always in operation during the cutting process, when it comes into contact with the wood chip 6, it can continuously cut the wood chip 6, thereby continuously pushing out the wood chips produced by the cutting. Therefore, the wood chip 6 will not interfere with the vertical falling path of the electric saw 14; at the same time, since the center of gravity of the counterweight platform 13 and the electric saw 14 as a whole is offset to one side of the counterweight platform 13, the electric saw 14 as a whole can always remain in a horizontal state during the cutting process.

[0076] For further information, see Figure 5 The feeding assembly includes a feeding motor 172, which is fixedly mounted on the adjusting block 18, and a gear is mounted on the output shaft of the feeding motor 172; a slide groove 171 is provided on the adjusting frame 17, and a rack meshing with the gear is provided in the slide groove 171; the gear is driven to rotate by the feeding motor 172, and the adjusting block 18 can be driven to move horizontally along the adjusting frame 17 under the meshing transmission of the gear and the rack; accordingly, a scale line 173 is also provided on the adjusting frame 17, and the horizontal spacing of the adjusting frame 17 relative to the electric saw 14 can be visually observed through the scale line 173.

[0077] In one embodiment, see Figure 4 The locking assembly 16 includes a sleeve 161, a wedge block 162, a limit block 163, and a third spring 164; the sleeve 161 is fixed on the fixing frame 11; the wedge block 162 is slidably arranged in the sleeve 161, and a limit block 163 is arranged on one side of the wedge block 162 located in the sleeve 161; the third spring 164 is arranged in the sleeve 161, and the two ends of the third spring 164 are respectively in contact with the wedge block 162 and the inner wall of the sleeve 161; wherein the traction rope 20 is connected to the wedge block 162;

[0078] In the initial state, the counterweight platform 13 is located at the upper end of the slide rail 12, and the wedge block 162 always extends out of the sleeve 161 under the elastic force of the third spring 164 until the limit block 163 contacts the slide rail 12, and the extended wedge block 162 contacts the lower end surface of the counterweight platform 13, thereby locking the counterweight platform 13; when the push plate 9 reaches the adjustment block 18, the traction rope 20 is pulled, so that the traction rope 20 pulls the wedge block 162 into the sleeve 161, and the counterweight platform 13 loses the locking effect of the wedge block 162, and thus moves downward along the slide rail 12 under the action of gravity, thereby driving the electric saw 14 to move downward synchronously, thereby realizing vertical cutting of the wood chips 6.

[0079] It should be noted that the traction rope 20 between the locking assembly 16 and the adjustment block 18 should always be kept straight. When the push plate 9 reaches the adjustment block 18, a pulling force can be applied to the traction rope 20, so that the wedge block 162 can be pulled by the traction rope 20.

[0080] Considering that the position of the adjusting block 18 on the adjusting frame 17 is adjustable, in order to ensure that the traction rope 20 between the locking assembly 16 and the adjusting block 18 can always remain in a straight state when the adjusting block 18 is in different positions on the adjusting frame 17, please refer to Figure 6 and Figure 7 , further comprising a rope clamping assembly 19, the rope clamping assembly 19 comprising a sliding sleeve 191 and a flexible clamp 192, the sliding sleeve 191 being slidably embedded in the adjusting block 18, the adjusting block 18 being provided with a cavity 181 for accommodating the sliding sleeve 191; the flexible clamp 192 being detachably connected to the sliding sleeve 191, the traction rope 20 movably passing through the flexible clamp 192 and the sliding sleeve 191;

[0081] Specifically, the traction rope 20 is passed through the flexible clamp 192 and the sliding sleeve 191. When the flexible clamp 192 is pushed into the sliding sleeve 191, the flexible clamp 192 is compressed and contracted, thereby clamping the traction rope 20. When the flexible clamp 192 is separated from the sliding sleeve 191, the flexible clamp 192 pops open, thereby releasing the traction rope 20.

[0082] After the adjusting block 18 moves to a certain position, the traction rope 20 is straightened, and then the flexible clamp 192 is pushed into the sliding sleeve 191 , and the traction rope 20 and the sliding sleeve 191 are relatively fixed by the flexible clamp 192 .

[0083] Further, in order to improve the fixing effect of the flexible clamp 192 on the traction rope 20, please refer to Figure 7 The end of the flexible clamp 192 away from the sliding sleeve 191 is evenly distributed with a plurality of flexible petals in the circumferential direction, and the flexible petals are provided with a plurality of spike portions 193, and the spike portions 193 are inclined toward one side of the sliding sleeve 191;

[0084] When the flexible clamp 192 is pushed into the sleeve 191, the flexible petals also gradually contract radially, so that the spike portion 193 contacts the traction rope 20 and penetrates into the traction rope 20. As the depth of the flexible clamp 192 entering the sleeve 191 gradually increases, the depth of the spike portion 193 penetrating into the traction rope 20 also increases. At the same time, the friction between the flexible clamp 192 and the sleeve 191 and the friction between the flexible petals and the traction rope 20 also gradually increase, so that the traction rope 20 and the sleeve 191 can be firmly fixed to prevent the traction rope 20 from becoming loose.

[0085] Since the sliding sleeve 191 has a certain movable space in the cavity 181, this space can be used to drive the traction rope 20 to pull the wedge block 162. Specifically, a first strap 21 can be provided on the sliding sleeve 191, and a second strap 22 adapted to the first strap 21 can be provided on the push plate 9.

[0086] When the wood piece 6 pushes the push plate 9 to move toward the side of the adjustment block 18, the second strap 22 on the push plate 9 gradually approaches the first strap 21 until the second strap 22 contacts the first strap 21, thereby pushing the first strap 21 to move synchronously, causing the sliding sleeve 191 to slide synchronously in the cavity 181. Since the traction rope 20 and the sliding sleeve 191 are relatively fixed, the traction rope 20 is driven to move synchronously, thereby pulling the wedge block 162.

[0087] In another embodiment, after the electric saw 14 completely cuts off the wood chips 6, the cut wood chips 6 fall down and are discharged from the discharge port 7, and the electric saw 14 needs to be reset upward to facilitate the cutting operation of the next group of wood chips 6; for this purpose, please refer to Figure 3 The upper end of the fixing frame 11 is fixedly mounted with an electromagnet 24 through a mounting seat 23, and an iron sheet 25 adapted to the electromagnet 24 is provided on the counterweight platform 13; the lower end of the fixing frame 11 is provided with a trigger button 26 electrically connected to the electromagnet 24 and the controller 37;

[0088] The controller 37 is also used to control the electromagnet 24 to turn on and start timing when the counterweight platform 13 presses the trigger button 26, and control the electromagnet 24 to turn off when the timing reaches the set time T;

[0089] The specific position of the trigger button 26 can be set according to the actual application. When the counterweight platform 13 contacts and presses the trigger button 26, the electric saw 14 can just completely cut off the wood chip 6. When the trigger button 26 is pressed, the electromagnet 24 is turned on, thereby generating a magnetic attraction force on the iron sheet 25, thereby driving the counterweight platform 13 and the electric saw 14 to move upward along the slide rail 12 and reset until the iron sheet 25 and the electromagnet 24 are attracted. During the upward process, the counterweight platform 13 pushes the wedge block 162 to retract into the sleeve 161 until the counterweight platform 13 slides up to the upper end of the slide rail 12. The wedge block 162 pops out again under the elastic force of the third spring 164 to lock the counterweight platform 13.

[0090] It should be noted that in order for the counterweight platform 13 to slide down by itself during the next cutting cycle, the electromagnet 24 cannot be in the on state all the time, which will cause the electromagnet 24 to consistently have a magnetic attraction to the iron sheet 25, thereby preventing the counterweight platform 13 from sliding down by itself. Therefore, it is necessary to set the electromagnet 24 to remain on for a period of time T and then disconnect after the trigger button 26 is pressed, where the time T can be set according to actual application, such as being on for 1 to 3S, as long as it can ensure that the counterweight platform 13 can slide up to the upper end of the slide rail 12 smoothly; when the time T is reached, the electromagnet 24 is powered off, and the counterweight platform 13 is no longer affected by the magnetic attraction of the electromagnet 24, and is only restricted by the wedge block 162 below it.

[0091] In addition, when the wood chip 6 pushes the push plate 9 to move, the first spring 10 is compressed. After the cut wood chip 6 falls into the feeding port 7, the push plate 9 slides and resets along the first guide rod 8 toward the side of the electric saw 14 under the elastic force of the first spring 10 until the push plate 9 contacts the wood chip 6 to be cut. Then, the wood chip 6 pushes the push plate 9 to feed again, and the next cycle of cutting can be carried out.

[0092] It should be noted that, due to the magnetic attraction of the electromagnet 24, the process of the counterweight platform 13 sliding up to the upper end of the slide rail 12 takes a very short time, so the counterweight platform 13 and the electric saw 14 can be reset before the push plate 9 contacts the wood chip 6 to be cut, thereby not affecting the next cycle of cutting operation of the electric saw 14.

[0093] In one embodiment, considering that there are gaps between adjacent wood chips 6 after being cut by the array cutting blade 2, when the electric saw 14 is horizontally sawing the wood chips 6, especially when the wood chips 6 are about to be cut off, the two sides of the wood chips 6 lack support, which causes the wood chips 6 to easily deviate to one side under the pulling action of the electric saw 14, and even cause the wood chips 6 to be torn; for this reason, please refer to Figure 8 , further comprising a translation frame 27, the translation frame 27 being slidably disposed in the feed port 7 and being located between the array cutting blade 2 and the push plate 9, a plurality of partitions 28 being rotatably disposed on the translation frame 27, and a driving assembly for driving the partitions 28 to rotate synchronously being disposed on the translation frame 27;

[0094] The partition 28 corresponds to the gaps between the wood pieces 6 one by one; when the partition 28 is unfolded horizontally, the partition 28 just contacts the wood pieces 6 on both sides; when the partition 28 is folded, the partition 28 is separated from the wood pieces 6 on both sides;

[0095] Specifically, each group of partitions 28 is first rotated to a folded state through the driving assembly. Before the wood chip 6 contacts the push plate 9, it needs to pass through the partitions 28 on the translation frame 27. Since the partitions 28 are aligned with the gaps between the corresponding wood chips 6 and the width of the partitions 28 when folded is smaller than the gap width, the partitions 28 will not affect the movement of the wood chips 6; when the wood chips 6 push the push plate 9 to reach the adjustment block 18, the driving assembly drives each partition 28 to rotate to an unfolded state at the same time. At this time, the partitions 28 just contact the wood chips 6 on both sides, so that each partition 28 is used to support the wood chips 6 laterally. In this way, during the cutting process, the wood chips 6 cannot undergo lateral displacement movement, thereby ensuring the stability of the wood chips 6 during cutting and preventing the wood chips 6 from being torn due to the pulling action of the electric saw 14.

[0096] See also Fig. 9 The driving assembly includes a swing rod 281, a push rod 282 and a cylinder 283. The swing rod 281 corresponds to each partition 28 one by one and is fixedly sleeved on the rotating shaft of the corresponding partition 28. The push rod 282 is rotatably connected to each swing rod 281. The fixed end of the cylinder 283 is rotatably mounted on the translation frame 27, and the extended end is rotatably connected to the push rod 282. The push rod 282 is pushed by the cylinder 283, thereby driving each swing rod 281 to rotate synchronously, so that each group of partitions 28 can be synchronously unfolded or folded.

[0097] The controller 37 is also used to control the driving assembly to drive each group of partitions 28 to rotate from the folded state to the unfolded state when the push plate 9 reaches the adjustment block 18; when the counterweight platform 13 presses the trigger button 26, the control driving assembly drives each group of partitions 28 to rotate from the unfolded state to the folded state;

[0098] In this way, when the push plate 9 reaches the adjustment block 18, that is, the wood chip 6 reaches the cutting length, the partition 28 is rotated to the expanded state, thereby providing lateral support for the wood chip 6 to facilitate subsequent stable cutting; and after the electric saw 14 completely cuts the wood chip 6, the partition 28 is rotated to the folded state, thereby releasing the lateral support for the wood chip 6, breaking the steady state of the wood chip 6, and providing space for displacement on both sides of the wood chip 6, which is convenient for the lateral displacement of the wood chip 6 and promotes the wood chip 6 to fall quickly into the discharge port 7.

[0099] Furthermore, since the cutting lengths of different woods vary greatly, the distances between the push plate 9 and the electric saw 14 during the cutting process are also different accordingly. In order to enable the partition 28 to provide a better lateral support effect during the cutting process, the distribution position of the translation frame 27 should also be adaptively adjusted according to different woods. The translation frame 27 should be located in the center between the push plate 9 and the electric saw 14 as much as possible. In this way, for the wood pieces 6 to be cut, the lengths on both sides of the translation frame 27 are roughly equal, that is, the distances between the electric saw 14 and the translation frame 27 and the distances between the translation frame 27 and the push plate 9 are roughly equal, so that the supporting effect of the partition 28 on the entire wood piece 6 to be cut is relatively balanced.

[0100] To do this, see Fig.10 , further comprising a second guide rod 29, a second spring 30, a pulley 31 and a cable 32, wherein the second guide rod 29 is provided with two groups and symmetrically arranged on both sides of the unloading port 7, and both sides of the translation frame 27 are slidably sleeved on the corresponding second guide rods 29; the pulley 31 is rotatably mounted on the translation frame 27; the cable 32 is wound on the pulley 31, one end of the cable 32 is fixedly connected to the push plate 9, and the other end is fixedly connected to the base 1; the second guide rod 29 is also movably sleeved with a second spring 30, and the second spring 30 is located between the translation frame 27 and the push plate 9;

[0101] Specifically, under the elastic force of the second spring 30, the cable 32 always remains in a taut and straightened state. When the wood chip 6 pushes the push plate 9 to move, under the traction of the cable 32, the pulley 31 is driven to rotate relative to the translation frame 27, thereby driving the translation frame 27 to slide along the second guide rod 29, and the sliding displacement distance of the translation frame 27 is always half of the displacement distance of the push plate 9. In this way, in the process of the wood chip 6 pushing the push plate 9 to move, the translation frame 27 can move synchronously with the push plate 9, and because the stroke of the translation frame 27 is always half of the push plate 9, the translation frame 27 is always in the center position between the electric saw 14 and the push plate 9, thereby providing a balanced and stable lateral support effect for the wood chip 6.

[0102] In another embodiment, in order to improve the shading and sealing effect of the wood slice 6 in actual application, the two side end surfaces of the wood slice 6 usually have a certain curvature change, and the cutting edge of the wood slice 6 obtained after the array cutting blade 2 saws the wood board is a straight cut surface, which requires a subsequent additional process to perform secondary processing on the two side end surfaces of the wood slice 6 to obtain the required curved surface;

[0103] To do this, see Fig.11 and Fig.12, further comprising a grinding frame 33, the grinding frame 33 being arranged on the base 1 and between the array cutting blade 2 and the electric saw 14, the grinding frame 33 being cross-arranged with a plurality of groups of first grinding rollers 34 and second grinding rollers 35 in sequence, and the grinding frame 33 being provided with a grinding motor for driving the first grinding rollers 34 and the second grinding rollers 35; wherein the contour line of the first grinding roller 34 is marked as S1, and the contour line of the second grinding roller 35 is marked as S2, and the contour line S1 and the contour line S2 are respectively adapted to the contours of the curved surfaces on both sides of the wood chip 6;

[0104] During the process of the push roller 4 pushing the wooden board and the wood chip 6 to feed, when the wood chip 6 passes through the grinding frame 33, the first grinding roller 34 and the second grinding roller 35 rotating on both sides of the wood chip 6 grind the end surfaces of both sides of the wood chip 6, so that the desired curved surface can be obtained, and multiple wood chips 6 can be processed synchronously at the same time, which has high processing efficiency and saves processing steps.

[0105] See also Fig.11 Guide plates 36 are symmetrically arranged on both sides of the grinding frame 33, and the distance between the guide plates 36 on both sides is adapted to the width of the wooden board, so as to guide the wood chip 6 and facilitate the wood chip 6 to enter the grinding area between the first grinding roller 34 and the second grinding roller 35.

[0106] It should be noted that, in this embodiment, in order to ensure the lateral support effect of the subsequent partitions 28 on the wood pieces 6, the edge contours on both sides of each partition 28 need to match the curved surface of the corresponding wood piece 6 when it is in the unfolded state.

[0107] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
