Description

Technical Field

[0001] The invention relates to the technical field of wood cutting equipment, in particular to a wood cutting equipment used for processing reconstituted wood. Background Art

[0002] Reconstituted wood (also called reconstituted wood or engineered wood) is a man-made board made by recombining small pieces of wood, wood fiber or other wood 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 is widely used in construction, furniture manufacturing, flooring, decoration and other fields. In order to obtain the required size and specific shape of reconstituted wood, it needs to be further cut.

[0003] At present, commonly used wood board 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 "push type"), and the other is to fix the wood board and then drive the electric saw to move for cutting (hereinafter referred to as "moving saw type").

[0004] In push-type cutting, the operator needs to manually push the board to make it contact with the saw blade, which not only increases the difficulty of operation, but also may cause the hand to approach the running saw blade due to improper operation, causing safety hazards. In addition, due to the manual pushing of the 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] The sliding saw cutting usually sets a cutting slit in the middle of the cutting table, so that the saw blade can only move in a straight line along this line, which limits the cutting mode it can perform and cannot complete some cutting tasks at special angles. Although the board remains fixed during the cutting process, after the cutting is completed, the board still needs to be removed from the cutting table and repositioned and fixed for the next cutting because the cutting saw cannot adjust the cutting position. This process is time-consuming and adds additional operating steps. Summary of the invention

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

The Y-axis moving platform on the three-axis moving platform can move backward to contact the pulling frame and push the pulling frame to move backward.

[0011] Preferably, a collection frame for collecting wood chips is connected to the lower part of the frame, rollers are provided on the left and right sides of the top of the rod frame to reduce the friction between the pressure block and the rod frame, and rollers are provided at intervals on the top of the support plate along its extension direction to reduce the friction between the wooden board and the support plate.

[0012] Preferably, the pressing member comprises an electric push rod mounted on the frame, and a pressing rod located at the lower side of 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, and the dust suction mechanism includes a mounting frame connected to the Y-axis moving platform of the three-axis moving platform, and a vacuum cleaner is installed on the mounting frame. The vacuum cleaner is connected to the saw blade guard on the circular electric saw through a dust suction hose.

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

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

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up multiple groups of rod frames, support plates and presses, sufficient support and fixation can be provided for the wooden board. The press block can move forward and backward synchronously with the circular saw. The movement of the press block can push the rod frame down one by one to drive the support plate to move down to avoid the circular saw. The rod frame moves down and pulls the press to swing away from the wooden board through the connecting plate to avoid the circular saw. The circular saw can be driven to rotate horizontally by an electric rotating rod to adjust the angle of the circular saw to cut the wooden board into a specific shape. It can provide sufficient support and fixation for the wooden board to ensure stability and accuracy during the cutting process, and can automatically avoid during the cutting process to adapt to different cutting needs, thereby improving production flexibility and product quality. The circular saw can be driven to perform three-axis mobile cutting of the wooden board through the three-axis mobile platform. There is no need to move the wooden board away to reposition and fix it for the next cutting, which greatly simplifies the operation steps and improves the cutting efficiency.

[0017] 2. The wooden board can be positioned by the positioning rod to avoid pushing the board too far backwards. The double-headed cylinder can drive the two pushing rods closer to each other and push the wooden board to the center to position the wooden board, ensuring that each wooden board can be placed precisely in the same position, thereby ensuring the consistency and accuracy of the cutting.

[0018] 3. The wood chips in the saw blade guard can be sucked out by a vacuum cleaner, effectively preventing the wood chips from being retained in the saw blade guard, ensuring the smooth operation of the saw blade and maintaining efficient cutting performance. The cooperation of the telescopic cover and soft hair can effectively seal the cutting area to prevent the wood chips from spreading everywhere and polluting the surrounding working environment, thereby improving the effect of wood chip absorption.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

The frame 1 is provided with two left and right pressing members 9 for pushing the rod frame 6 downward. The pressing member 9 includes two front and rear electric push rods 91 installed on the frame 1, and a pressing rod 92 is connected between the telescopic rods of the front and rear electric push rods 91. The pressing rod 92 is located at the lower side of the mounting plate 5 and contacts with the inner bottom surface of the rod frame 6. The Y-axis moving platform 21 of the three-axis moving platform 2 is connected with two left and right pressing blocks 11. The length of the pressing block 11 is greater than the saw blade diameter of the circular electric saw 4. The front and rear sides of the pressing block 11 are both inclined. When the pressing block 11 moves forward and backward, its upper inclined surface can contact with the rod frame 6 and push the rod frame 6 downward. The left and right sides of the top of the rod frame 6 are rotatably provided with rollers 61. The friction between the pressure block 11 and the rod frame 6 can be reduced by roller 1 61, so that the pressure block 11 can slide on the rod frame 6 smoothly and steadily, reducing the wear of the pressure block 11 and the rod frame 6, and extending the service life of the pressure block 11 and the rod frame 6. The top of the support plate 7 is provided with roller 2 71 that rotates at intervals along its extension direction. The friction between the wooden board and the support plate 7 can be reduced by roller 2 71, so that the wooden board can move smoothly and steadily on the support plate 7, reducing the wear on the surface of the wooden board and the surface of the support plate 7, and extending the service life of the support plate 7. The lower part of the frame 1 is connected to a collecting frame 20 for collecting wood chips. The inner bottom surface of the collecting frame 20 is an inclined surface with a high front and a low rear so as to guide the wood chips backwards, and the rear side of the collecting frame 20 is open to automatically discharge the wood chips backwards.

[0032] First, the electric push rod 91 is controlled to drive the lower pressure rod 92 to move downward, and the lower pressure rod 92 moves downward to push all the rod frames 6 to move downward synchronously, and the support spring 12 is stretched accordingly, and the rod frame 6 moves downward to pull the pressing tool 8 to swing away from the pallet 7 through the connecting plate 10, so as to facilitate the subsequent placement of the wooden board on the pallet 7. Then, the wooden board to be cut is pushed backward onto the pallet 7, and then the electric push rod 91 is controlled 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 upward, and the rod frame 6 moves upward to push the pressing tool 8 to swing toward the pallet 7 through the connecting plate 10, so as 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 toward the direction close to the support plate 7 until it contacts the wooden board, the inverted T-shaped pressure rod 84 cannot continue to swing. At this time, the slide plate 82 continues to swing toward the direction close to the support plate 7 to compress the support spring 85. This not only ensures 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 provides a buffer when the inverted T-shaped pressure rod 84 contacts the wooden board to avoid damage to the wooden board surface caused by hard collision, and can also adapt to wooden boards of different thicknesses. Manually rotating the screw rod 83 can make the screw rod 83 drive the slide plate 82 to adjust its position in the left and right directions, thereby driving the inverted T-shaped pressure rod 84 to adjust its position in the left and right directions to adapt to wooden boards of different sizes, thereby enhancing the versatility and flexibility of the equipment.

[0033] After the wood board is fixed, the three-axis mobile platform 2 is controlled to work, so as to drive the electric rotating rod 3 to drive the circular electric saw 4 to move forward, backward, left, right, up and down in three axes to cut the wood board, so as to cut the wood board into the required size. The electric rotating rod 3 is controlled to work, so as to drive the circular electric saw 4 to rotate horizontally, so as to adjust the angle of the circular electric saw 4, so as to realize cutting the wood board into a specific shape. When the Y-axis mobile platform 21 on the three-axis mobile platform 2 drives the circular electric saw 4 to cut forward, it also drives the pressing block 11 to move forward. When the front side inclined surface of the pressing block 11 moves forward to contact the rod frame 6, the pressing block 11 continues to move forward and squeezes the rod frame 6 downward through the inclined surface of its front side. The rod frame 6 moves downward and pulls the pressing tool 8 to swing away from the support plate 7 through the connecting plate 10 to separate from the wood board, so as to avoid the circular electric saw 4 and avoid hindering the circular electric saw 4 from moving to cut the wood board. The rod frame 6 moves downward and drives the support plate 7 to move downward to avoid the circular electric saw 4 and avoid hindering the circular electric saw 4 from moving to cut the wood board, thereby ensuring that the wood board cutting work proceeds smoothly. The remaining rods 6 that are not squeezed and moved down by the pressing block 11 remain in the raised state, so that the corresponding support plate 7 is also maintained in the raised position, continuing to support the wooden board, and the corresponding pressing tool 8 also maintains the state of pressing and fixing the wooden board, ensuring that the wooden board remains stable and flat during the entire cutting process. Therefore, the device can not only provide sufficient support and fixation for the wooden board to ensure 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, and do not need to move the wooden board away for the next cutting to reposition and fix it, which greatly simplifies the operation steps and improves the cutting efficiency. The rod frame 6 moves downward to stretch the support spring 12. When the pressing block 11 moves and separates from the rod frame 6, under the reset action of the support spring 12, the rod frame 6 is pulled upward to reset, so that the pressing tool 8 swings and resets in the direction close to the support plate 7 to press and fix the wooden board again. Similarly, when the Y-axis moving platform 21 on the three-axis moving platform 2 drives the circular electric saw 4 and the pressing block 11 to perform cutting work backward, the support plate 7 and the pressing tool 8 can also avoid the circular electric saw 4. When the cutting of the wooden board is completed, the electric push rod 91 is controlled to drive the pressing rod 92 to move downward, so as to push all the rod frames 6 to move downward synchronously, so that all the pressing tools 8 are synchronously swung away from the supporting plate 7 to release the wooden board, so as to facilitate the subsequent taking and placing of the wooden board.

[0034] See also Figure 6-Figure 8The frame 1 is provided with a positioning mechanism, which 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, and two left and right 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, and the telescopic rods on both sides of the double-headed cylinder 134 are respectively connected to the two push rods 133. The rear side of the top of the lifting frame 132 is connected to two left and right positioning rods 135, and the positioning rods 135 are located on the rear side of the rearmost mounting plate 5. The inner bottom surface of the fixed frame 131 is provided with a pushing component for pushing the lifting frame 132 to rise and fall, and the pushing component includes a sliding rod slidably connected to the inner bottom surface of the fixed frame 131 136, a tension spring 139 is connected between the slide bar 136 and the fixed frame 131, and the bottom of the lifting frame 132 is connected to two front and rear groups of slotted inclined plates 138, each group of slotted inclined plates 138 has two slotted inclined plates 138, and the two slotted inclined plates 138 in each group are arranged on the left and right. The front side of the slide bar 136 is connected to two front and rear groups of push rods 137, each group of push rods 137 has two slotted inclined plates, and the two push rods 137 in each group are arranged on the left and right. The four push rods 137 are respectively located in the grooves of the four slotted inclined plates 138, and the rear side of the slide bar 136 is connected to the pulling frame 130. 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.

[0035] 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.

[0036] See also Figure 6 and Fig. 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.

[0037] 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.

[0038] See also Figure 9-10 The bottom of the saw blade guard 41 on the circular electric saw 4 is connected to a telescopic cover 15, and soft bristles 16 are connected to the bottom of the telescopic cover 15 at intervals along the circumferential direction. The left and right outer walls of the saw blade guard 41 on the circular electric saw 4 are connected to two front and rear guide sleeves 17, and each guide sleeve 17 is slidably connected to a lifting rod 18. The lower part of the lifting rod 18 is connected to the outer wall of the telescopic cover 15, and the upper part of the lifting rod 18 is covered with a reset spring 19, and the two ends of the reset spring 19 are respectively connected to the lifting rod 18 and the guide sleeve 17.

[0039] Through the cooperation of the telescopic cover 15 and the soft hair 16, the cutting area can be effectively sealed to prevent wood chips from spreading everywhere and polluting the surrounding working environment, thereby improving the effect of wood chip absorption. The setting of the soft hair 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 moves down with the saw blade guard 41 and contacts the wood surface, the telescopic cover 15 cannot move down further, so the saw blade guard 41 continues to move down to compress the telescopic cover 15, and the telescopic cover 15 stretches and resets when the saw blade guard 41 moves up. Through the cooperation of the guide sleeve 17 and the lifting rod 18, precise guidance can be provided for the telescopic action of the telescopic cover 15, ensuring that the telescopic cover 15 always remains in an upright state and preventing the telescopic cover 15 from twisting and breaking. The reset spring 19 can assist the telescopic cover 15 in stretching and resetting.

It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
