Description

Technical Field

[0001] The present invention relates to the technical field of wood cutting equipment, and particularly to a wood cutting equipment for the processing of reconstituted wood. Background Art

[0002] Reconstituted wood boards (also known as reconstituted wood or engineered wood) are artificial boards formed by recombining small pieces of wood, wood fibers or other woody materials and bonding them with adhesives. This material usually has more uniform properties than natural wood and can better control dimensional stability, strength and appearance. Therefore, reconstituted wood boards are widely used in the fields of construction, furniture manufacturing, flooring, decoration, etc. In order to obtain reconstituted wood boards of the required size and specific shape, further cutting treatment is required.

[0003] Currently, commonly used wood cutting machines are mainly divided into two types: one is to fix the electric saw and push the wood board to move for cutting (hereinafter referred to as "pushing material type"), and the other is to fix the wood board and drive the electric saw to move for cutting (hereinafter referred to as "moving saw type").

[0004] In pushing material type cutting, the operator needs to manually push the wood board to make it contact with the saw blade, which not only increases the operation difficulty, but also may cause the hand to approach the running saw blade due to improper operation, resulting in safety hazards. In addition, due to manually pushing the wood board, it is difficult to maintain the consistency and accuracy of the cutting path, especially in fine cutting, it is difficult to ensure the quality of each cut.

[0005] Moving saw type cutting usually sets a cutting slot in the middle of the cutting table, so that the saw blade can only move linearly along this line, which limits the cutting modes it can perform and cannot complete some special angle cutting tasks. Although the wood board remains fixed during the cutting process, after cutting, since the cutting saw cannot adjust the cutting position, the wood board still needs to be removed from the cutting table and repositioned and fixed for the next cut. This process is both time-consuming and adds extra operation steps. Summary of the Invention

[0006] The purpose of the present invention is to provide a wood cutting equipment for the processing of reconstituted wood, aiming to both provide support and fixation for the wood board to ensure stability and accuracy during the cutting process, and be able to automatically avoid during the cutting process to adapt to different cutting requirements, improve production flexibility and product quality.

[0007] To achieve the above object, the present invention provides the following technical solution: A wood cutting device for the processing of recombined wood, comprising a frame. A three-axis moving platform is installed on the top of the frame. An electric rotating rod is provided on the three-axis moving platform, and a circular saw is installed on the electric rotating rod. A plurality of groups of mounting plates are evenly spaced from front to back on the frame. The number of each group of mounting plates is two. A liftable rod frame is provided on each mounting plate. A support plate for supporting a wooden board is connected to the top of each rod frame. A support spring is spacedly connected between the inner bottom surface of the rod frame and the bottom surface of the mounting plate. Two left and right pressing tools are hinged between the two mounting plates in each group. A connecting plate is hinged on the pressing tool, and the lower part of the connecting plate is hinged on the rod frame. Two left and right pressing members for pushing the rod frame to move downward are installed on the frame. Two left and right pressing blocks are connected to the Y-axis moving platform of the three-axis moving platform. The front and back movement of the pressing block can contact the rod frame and push the rod frame to move downward. The downward movement of the rod frame drives the support plate to move downward to avoid the circular saw. The downward movement of the rod frame pulls the pressing tool to swing away from the support plate and separate from the wooden board through the connecting plate to avoid the circular saw.

[0008] Preferably, the pressing tool includes a swing plate hinged between the two mounting plates in each group. A sliding plate is slidably provided on the upper part of the swing plate. A nut is installed on the upper part of the swing plate. A screw rod is threadedly connected in the nut. The screw rod is rotatably connected to the sliding plate. An inverted T-shaped pressing rod is slidably connected to the sliding plate. A support spring is connected between the inverted T-shaped pressing rod and the sliding plate. The upper part of the connecting plate is hinged on the swing plate.

[0009] Preferably, a positioning mechanism is provided on the frame. The positioning mechanism includes a fixed frame connected to the frame. An elevating frame is provided on the fixed frame and is located below the rod frame. Two left and right pushing rods are slidably provided on the front side of the elevating frame. A double-headed cylinder is installed at the bottom of the elevating frame. The expansion rods on both sides of the double-headed cylinder are respectively connected to the two pushing rods. A positioning rod is connected to the rear side of the top of the elevating frame and is located behind the last mounting plate. A pushing component for pushing the elevating frame to move up and down is provided on the inner bottom surface of the fixed frame.

[0010] Preferably, the pushing component includes a sliding rod slidably connected to the inner bottom surface of the fixed frame. A tension spring is connected between the sliding rod and the fixed frame. A slotted inclined plate is connected to the bottom of the elevating frame. A pushing rod is connected to the front side of the sliding rod and is located in the slot of the slotted inclined plate. A pulling frame is connected to the rear side of the sliding rod. The backward movement of the Y-axis moving platform on the three-axis moving platform can contact the pulling frame and push the pulling frame to move backward.

[0011] Preferably, a collection box for collecting wood chips is connected to the lower part inside the frame. Roller 1s are provided on the left and right sides of the top of the rod frame to reduce the friction between the pressing block and the rod frame. Roller 2s are provided at intervals along the extending direction of the top of the support plate to reduce the friction between the wooden board and the support plate.

[0012] Preferably, the pressing member includes an electric push rod installed on the frame, and a pressing rod located below the mounting plate is connected to the telescopic rod of the electric push rod.

[0013] Preferably, a dust suction mechanism is provided on the Y-axis moving platform of the three-axis moving platform. The dust suction mechanism includes a mounting frame connected to the Y-axis moving platform of the three-axis moving platform. A vacuum cleaner is installed on the mounting frame, and the vacuum cleaner is communicated with the saw blade guard on the circular saw through a dust suction hose.

[0014] Preferably, a telescopic cover is connected to the bottom of the saw blade guard on the circular saw, and soft hairs are connected to the bottom of the telescopic cover at intervals along the circumference.

[0015] Preferably, lifting rods are slidably connected to the outer walls on the left and right sides of the saw blade guard on the circular saw through guide sleeves. The lower part of the lifting rod is connected to the outer wall of the telescopic cover, and a return spring is connected between the lifting rod and the guide sleeve.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. By providing multiple sets of rod frames, support plates and pressing tools, sufficient support and fixation can be provided for the wooden board. The pressing block can move forward and backward synchronously with the circular saw. The movement of the pressing block can push the rod frame down one by one to drive the support plate to move down to avoid the circular saw. And when the rod frame moves down, it pulls the pressing tool to swing away from the wooden board through the connecting plate to avoid the circular saw. The electric rotating rod can drive the circular saw to rotate horizontally to adjust the angle of the circular saw, so as to cut the wooden board into a specific shape. It achieves the effect of both providing sufficient support and fixation for the wooden board to ensure the stability and accuracy during the cutting process, and being able to automatically avoid during the cutting process to adapt to different cutting requirements, improving production flexibility and product quality. The three-axis moving platform can drive the circular saw to perform three-axis moving cutting of the wooden board, without moving the wooden board away for repositioning and fixing for the next cutting, greatly simplifying the operation steps and improving the cutting efficiency.

[0018] 2. The positioning rod can be used to position the wooden board to prevent the wooden board from being pushed backward excessively. The double-headed cylinder can drive the two pushing rods to approach each other to push the wooden board to the center for positioning the wooden board, ensuring that each wooden board can be accurately placed in the same position, thus ensuring the consistency and accuracy of cutting.

[0019] 3. The vacuum cleaner can suck out the wood chips in the saw blade guard, effectively preventing the wood chips from staying in the saw blade guard, ensuring the smooth operation of the saw blade and maintaining high cutting performance. Through the cooperation of the telescopic cover and the soft hairs, the cutting area can be effectively sealed to prevent the wood chips from spreading everywhere and avoiding polluting the surrounding working environment, thereby improving the effect of wood chip suction.

Detailed implementation manners

[0031] The present application will be further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Please refer to Figures 1-5, a wood cutting device for the processing of recombined wood, comprising a frame 1. A three-axis moving platform 2 is installed on the top of the frame 1. An electric rotating rod 3 is provided on the three-axis moving platform 2. The electric rotating rod 3 includes a motor and a rotating rod. The motor is installed on the three-axis moving platform 2. The rotating rod is rotatably connected to the three-axis moving platform 2 and connected to the output shaft of the motor. A circular saw 4 is installed at the lower part of the rotating rod. Through the three-axis moving platform 2, the electric rotating rod 3 can be driven to drive the circular saw 4 to move in the three axes of front-back, left-right, and up-down to cut the wooden board. The three-axis moving platform 2 is a prior art and will not be elaborated here. Five groups of mounting plates 5 are evenly spaced from front to back on the frame 1. The number of each group of mounting plates 5 is two. A liftable rod frame 6 is slidably provided on each mounting plate 5. A support plate 7 for supporting the wooden board is connected to the top of each rod frame 6. The support plate 7 is located above the mounting plate 5. Four support springs 12 are spaced from left to right between the inner bottom surface of the rod frame 6 and the bottom surface of the mounting plate 5. Two left and right pressing tools 8 are hinged between the two mounting plates 5 in each group. The pressing tool 8 includes a swing plate 81 hinged between the two mounting plates 5 in each group. A chute is opened on the upper part of the swing plate 81. A sliding plate 82 is slidably connected in the chute. A nut 86 is installed on the upper part of the swing plate 81. A screw rod 83 is threadedly connected in the nut 86. The screw rod 83 is rotatably connected to the sliding plate 82. An inverted T-shaped pressing rod 84 is slidably connected to the sliding plate 82. A support spring 85 is connected between the inverted T-shaped pressing rod 84 and the sliding plate 82. A connecting plate 10 is hinged on the swing plate 81. The lower part of the connecting plate 10 is hinged on the rod frame 6 in front of it. Two left and right downward pressing members 9 for pushing the rod frame 6 to move downward are installed on the frame 1. The downward pressing member 9 includes two front and rear electric push rods 91 installed on the frame 1. A downward pressing rod 92 is connected between the telescopic rods of the two front and rear electric push rods 91. The downward pressing rod 92 is located below the mounting plate 5 and contacts the inner bottom surface of the rod frame 6. Two left and right pressing blocks 11 are connected to the Y-axis moving platform 21 of the three-axis moving platform 2. The length of the pressing block 11 is greater than the diameter of the saw blade of the circular saw 4. Both the front and rear sides of the pressing block 11 are designed as inclined surfaces. When the pressing block 11 moves back and forth, its upper inclined surface can contact the rod frame 6 and push the rod frame 6 to move downward. Roller wheels 61 are rotatably provided on both the left and right sides of the top of the rod frame 6. Through the roller wheels 61, the friction between the pressing block 11 and the rod frame 6 can be reduced, so that the pressing block 11 can slide smoothly and steadily on the rod frame 6, reducing the wear of the pressing block 11 and the rod frame 6 and extending the service life of the pressing block 11 and the rod frame 6. Roller wheels 71 are rotatably provided at intervals along the extending direction of the top of the support plate 7. Through the roller wheels 71, the friction between the wooden board and the support plate 7 can be reduced, so that the wooden board can move smoothly and steadily on the support plate 7, reducing the wear of the surface of the wooden board and the surface of the support plate 7 and extending the service life of the support plate 7. A collection box 20 for collecting wood chips is connected to the lower part inside the frame 1. The inner bottom surface of the collection box 20 is an inclined surface with the front high and the rear low to guide the wood chips backward. The rear side of the collection box 20 is provided in an open manner to automatically discharge the wood chips backward.

[0033] First, control the electric push rod 91 to drive the lower pressure rod 92 to move downward. The downward movement of the lower pressure rod 92 pushes all the rod frames 6 to move downward synchronously, and the support spring 12 is stretched accordingly. The downward movement of the rod frame 6 pulls the pressing tool 8 to swing away from the pallet 7 through the connecting plate 10, so as to facilitate placing the wooden board on the pallet 7 subsequently. Then, push the wooden board to be cut backward onto the pallet 7, and then control the electric push rod 91 to drive the lower pressure rod 92 to move upward and reset. Under the reset action of the support spring 12, the rod frame 6 is pulled to move upward. The upward movement of the rod frame 6 pushes the pressing tool 8 to swing towards the pallet 7 through the connecting plate 10 to press and fix the wooden board on the pallet 7. When the inverted T-shaped pressure rod 84 on the pressing tool 8 swings towards the pallet 7 and contacts the wooden board, the inverted T-shaped pressure rod 84 cannot continue to swing. At this time, the sliding plate 82 continues to swing towards the pallet 7 to compress the support spring 85. In this way, it can not only ensure that the inverted T-shaped pressure rod 84 firmly presses the wooden board to prevent the wooden board from moving during the cutting process, but also provide buffering when the inverted T-shaped pressure rod 84 contacts the wooden board to avoid damage to the surface of the wooden board caused by hard collision, and can also adapt to wooden boards of different thickness specifications. Manually rotate the screw rod 83, and the screw rod 83 can drive the sliding plate 82 to adjust the position in the left-right direction, so as to drive the inverted T-shaped pressure rod 84 to adjust the position in the left-right direction to adapt to wooden boards of different specifications and sizes, enhancing the versatility and flexibility of the equipment.

[0034] After the wooden board is fixed, control the three-axis moving platform 2 to work, so as to drive the electric rotating rod 3 to drive the circular saw 4 to move in the three axes of front, back, left, right, up and down to cut the wooden board, so as to cut the wooden board into the required size. Control the electric rotating rod 3 to work, and the circular saw 4 can be driven to rotate horizontally to adjust the angle of the circular saw 4, so as to cut the wooden board into a specific shape. When the Y-axis moving platform 21 on the three-axis moving platform 2 drives the circular saw 4 to move forward for cutting work, it also drives the pressing block 11 to move forward. When the front inclined surface on the pressing block 11 moves forward to contact the rod holder 6, the pressing block 11 continues to move forward and squeezes the rod holder 6 to move down through the inclined surface on its front side. The rod holder 6 moves down and pulls the pressing tool 8 to swing away from the pallet 7 and separate from the wooden board to avoid the circular saw 4 and prevent the circular saw 4 from moving to cut the wooden board. The rod holder 6 moves down and drives the pallet 7 to move down to avoid the circular saw 4 and prevent the circular saw 4 from moving to cut the wooden board, so as to ensure the smooth progress of the wooden board cutting work. The remaining rod holders 6 that are not squeezed and moved down by the pressing block 11 remain in the raised state, so that the corresponding pallets 7 are also maintained in the raised position to continue supporting the wooden board, and the corresponding pressing tools 8 also maintain the state of pressing and fixing the wooden board, ensuring that the wooden board remains stable and flat during the entire cutting process. Therefore, this equipment can not only provide sufficient support and fixation for the wooden board to ensure the stability and accuracy during the cutting process, but also automatically avoid during the cutting process to adapt to different cutting requirements, improve production flexibility and product quality, without having to move the wooden board away for repositioning and fixing for the next cutting, greatly simplifying the operation steps and improving the cutting efficiency. The rod holder 6 moves down and stretches the support spring 12. When the pressing block 11 moves away from the rod holder 6, under the reset action of the support spring 12, the rod holder 6 is pulled up and reset, so that the pressing tool 8 swings back towards the pallet 7 to re-press and fix the wooden board. Similarly, when the Y-axis moving platform 21 on the three-axis moving platform 2 drives the circular saw 4 and the pressing block 11 to move backward for cutting work, the pallet 7 and the pressing tool 8 can also avoid the circular saw 4. When the wooden board cutting is completed, control the electric push rod 91 to drive the lower pressing rod 92 to move down, so as to push all the rod holders 6 to move down synchronously, so that all the pressing tools 8 swing away from the pallet 7 synchronously to loosen the wooden board, facilitating the subsequent picking and placing of the wooden board.

[0035] Please refer to Figures 6-8, a positioning mechanism is provided on the frame 1. The positioning mechanism includes a fixed frame 131 connected to the frame 1. A lifting frame 132 located below the rod frame 6 is slidably provided on the fixed frame 131. Two push rods 133 are slidably provided on the front side of the lifting frame 132. A double-headed cylinder 134 is installed at the bottom of the lifting frame 132. The telescopic rods on both sides of the double-headed cylinder 134 are respectively connected to the two push rods 133. Two positioning rods 135 are connected to the rear side of the top of the lifting frame 132. The positioning rods 135 are located at the rear side of the rearmost mounting plate 5. A pushing component for pushing the lifting frame 132 to lift is provided on the inner bottom surface of the fixed frame 131. The pushing component includes a sliding rod 136 slidably connected to the inner bottom surface of the fixed frame 131. A tension spring 139 is connected between the sliding rod 136 and the fixed frame 131. Two groups of grooved inclined plates 138 are connected to the bottom of the lifting frame 132. The number of each group of grooved inclined plates 138 is two. The two grooved inclined plates 138 in each group are arranged left and right. Two pushing rods 137 are connected to the front side of the sliding rod 136. The number of each group of pushing rods 137 is two. The two pushing rods 137 in each group are arranged left and right. The four pushing rods 137 are respectively located in the grooves of the four grooved inclined plates 138. A pulling frame 130 is connected to the rear side of the sliding rod 136. The Y-axis moving platform 21 on the three-axis moving platform 2 can move backward to contact the pulling frame 130 and push the pulling frame 130 to move backward.

[0036] In the initial state, the Y-axis moving platform 21 on the three-axis moving platform 2 pushes the pulling frame 130 backward, and the tension spring 139 is in a stretched state. At the same time, the pushing rod 137 supports the slotted inclined plate 138, and props up the lifting frame 132, so that the push rod 133 and the positioning rod 135 are both in the rising position. The positioning rod 135 can be used to position the wooden board to prevent the wooden board from being pushed too far backward. The double-headed cylinder 134 is controlled to drive the left and right push rods 133 to move closer to each other, so that the wooden board can be moved to the center, so that the wooden board can be positioned to ensure that each wooden board can be accurately placed in the same position, thereby ensuring the consistency and accuracy of the cutting. Then the double-headed cylinder 134 is controlled to drive the two pushing rods 133 to move away from each other and disengage from the wooden board. When the Y-axis moving platform 21 on the three-axis moving platform 2 drives the circular electric saw 4 forward to perform cutting work, the Y-axis moving platform 21 on the three-axis moving platform 2 disengages from the pulling frame 130. Under the reset action of the tension spring 139, the pulling slide bar 136 drives the pulling frame 130 and the pushing rod 137 to move forward. The pushing rod 137 moves forward to push the slotted inclined plate 138 downward, thereby pulling the lifting frame 132 to carry the pushing rod 133 and the positioning rod 135 downward to avoid the circular electric saw 4, avoid hindering the circular electric saw 4 from moving to cut the wooden board, and ensure that the wooden board cutting work proceeds smoothly. When the Y-axis moving platform 21 on the three-axis moving platform 2 drives the circular electric saw 4 to move backward to complete the cutting of the wooden board, the Y-axis moving platform 21 on the three-axis moving platform 2 continues to move backward to contact the pulling frame 130, and pushes the pulling frame 130 to move backward, thereby pulling the sliding rod 136 and the pushing rod 137 to move backward, stretching the tension spring 139, and the pushing rod 137 moves backward to push the slotted inclined plate 138 to move upward. The slotted inclined plate 138 moves upward and pushes the lifting frame 132 to move upward, thereby causing the pushing rod 133 and the positioning rod 135 to rise, preparing for positioning the next wooden board.

[0037] See also Figure 6 and Figure 9 A dust suction mechanism is provided on the Y-axis moving platform 21 of the three-axis moving platform 2, and the dust suction mechanism includes a mounting frame 141 connected to the Y-axis moving platform 21 of the three-axis moving platform 2, and a dust collector 142 is installed on the rear side of the mounting frame 141. The dust collector 142 is connected to the saw blade guard 41 on the circular electric saw 4 through a dust suction hose 143.

[0038] When the saw blade of the circular electric saw 4 rotates to cut wood, wood chips are easily brought into the saw blade guard 41. As the wood chips retained in the saw blade guard 41 increase, the saw blade guard 41 is easily blocked, causing the saw blade to get stuck, affecting cutting efficiency and safety. The vacuum cleaner 142 is controlled to work, and the wood chips in the saw blade guard 41 can be sucked into the vacuum cleaner 142 through the vacuum hose 143 in time for collection, effectively preventing wood chips from being retained in the saw blade guard 41, ensuring smooth operation of the saw blade, and maintaining efficient cutting performance. The vacuum cleaner 142 is a prior art and will not be described in detail here.

[0039] Please refer to Figures 9-10 Figures 9-10 , a telescopic cover 15 is connected to the bottom of the saw blade guard 41 on the circular saw 4. Soft bristles 16 are circumferentially and spacedly connected to the bottom of the telescopic cover 15. Two front and rear guide sleeves 17 are connected to the outer walls on the left and right sides of the saw blade guard 41 on the circular saw 4. A lifting rod 18 is slidably connected in each guide sleeve 17. The lower part of the lifting rod 18 is connected to the outer wall of the telescopic cover 15. A return spring 19 is sleeved on the upper part of the lifting rod 18. The two ends of the return spring 19 are respectively connected to the lifting rod 18 and the guide sleeve 17.

[0040]

[0040] Through the cooperation of the telescopic cover 15 and the soft bristles 16, the cutting area can be effectively sealed, preventing wood chips from spreading everywhere, avoiding polluting the surrounding working environment, and thus improving the effect of wood chip suction. The setting of the soft bristles 16 not only enhances the sealing performance, but also protects the surface of the wooden board, preventing the telescopic cover 15 from directly contacting the wood and causing surface wear. After the telescopic cover 15 follows the saw blade guard 41 and moves down to contact the wood surface, the telescopic cover 15 cannot continue to move down. Thus, when the saw blade guard 41 continues to move down, the telescopic cover 15 is compressed, and when the saw blade guard 41 moves up, the telescopic cover 15 extends and resets. Through the cooperation of the guide sleeve 17 and the lifting rod 18, accurate guidance can be provided for the telescopic movement of the telescopic cover 15, ensuring that the telescopic cover 15 always remains upright and preventing the telescopic cover 15 from being twisted and broken. The return spring 19 can assist the telescopic cover 15 to extend and reset.

[0041] The above embodiments only represent the preferred embodiments of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several variations, improvements and substitutions can be made, and these all belong to the protection scope of the present invention.
