Description

Technical Field

[0001] The present invention belongs to the technical field of wood strip punching, and particularly relates to an automatic wood strip punching device for furniture production. Background Art

[0002] Furniture production includes a machining section, a painting section, and a packaging section. The machining section requires various woods, including wood strips, and the wood strips need to be punched for installation. The existing wood strip punching devices generally require manual clamping of the wood strips with jigs, and then removing the wood strips after punching, resulting in low feeding and discharging efficiency.

[0003] A Chinese patent with the patent publication number CN109910113B discloses a wood strip board punching device, including a base, a first frame, a mounting plate, a motor, a cam, a first pulley, etc. The top of the base is provided with a first frame, and a mounting plate is connected between the lower parts on the left and right sides inside the first frame.

[0004] This patent feeds the wood strip board through a flat plate, and punches the wood strip board through a bracket. Although the hinge block can limit the wood strip board in the left - right direction, the leaf spring has elasticity, which will cause the wood strip board to displace during the punching process, and it is difficult to fix and limit the position of the limiting plate in the front - back direction, with poor limiting effect. Moreover, the lengths, widths, and thicknesses of wood strip boards of different specifications are different, and it is inconvenient to adjust the size of the blanking box at any time, so the practicability needs to be improved. Summary of the Invention

[0005] In order to solve the problems of poor limiting effect on the wood strips during punching and inconvenient adjustment of the size of the blanking box at any time in the prior art, the present invention provides an automatic wood strip punching device for furniture production.

[0006] The technical solution of the present invention is as follows: An automatic punching device for wooden strips in furniture production, including a workbench, a support plate is connected to the workbench, a row of surface electric punching heads and a pair of end electric punching heads are arranged on the front side of the support plate, and a control mechanism for controlling the movement of the surface electric punching heads and the end electric punching heads is arranged on the support plate; two moving frames that move in the X-axis direction are arranged on the workbench, a lifting plate that moves in the Z-axis direction is slidably connected to each moving frame, and a limiting plate that moves in the Y-axis direction is slidably connected to the middle of each moving frame; the positions of the moving frames, the lifting plates and the limiting plates are adjusted through an adjusting mechanism to adapt to wooden strips of different specifications; two electric slide rails one that move in the X-axis direction are installed on the top of the workbench, a feeding plate that moves in the Y-axis direction is installed on each electric slide rail one, two pairs of triangular blocks for pushing the wooden strips are slidably connected to each feeding plate, fixing plates are connected to the mutually remote sides of the two electric slide rails one, a limiting block that moves in the X-axis direction is slidably connected to each fixing plate, the triangular blocks and the limiting blocks are reset by return springs, and after punching is completed, the limiting blocks are loosened from the wooden strips through an extrusion mechanism.

[0007] Optionally, a feeding groove for placing the wooden strips to be punched is formed between the lifting plate and the limiting plate; a discharging opening is formed between the workbench and the support plate, and the triangular blocks push the punched wooden strips towards the discharging opening for discharging.

[0008] Optionally, a discharging opening is formed between the bottom end of the lifting plate and the moving frame, and the size of the discharging opening is different when the lifting plate moves in the Z-axis direction to adapt to the discharging of single wooden strips of different thicknesses through the discharging opening.

[0009] Optionally, the control mechanism includes a three-axis control platform one and a three-axis control platform two. The three-axis control platform one and the three-axis control platform two are installed on the front side of the support plate. The surface electric punching head is installed on the three-axis control platform one, and the end electric punching head is installed on the three-axis control platform two.

[0010] Optionally, the adjusting mechanism includes a guide rail. The guide rail is connected to the top of the workbench. A bidirectional lead screw is rotatably connected to the guide rail. The moving frames are all threadedly connected to the bidirectional lead screw. When the bidirectional lead screw rotates, the two moving frames move in opposite directions; gears are rotatably connected to the moving frames, and racks meshing with the gears are connected to the lifting plates; screws are rotatably connected to the middle of the moving frames, knobs are connected to the ends of the screws, and nuts threadedly connected to the screws are connected to the limiting plates.

[0011] Optionally, right-angle portions are arranged on the upper parts of the limiting blocks, and the wooden strips during punching are limited through the right-angle portions.

[0012] Optionally, the extrusion mechanism includes a connecting plate. One side of each of the two feeding plates facing away from each other is connected to a connecting plate by bolts. A row of mounting holes is provided in the connecting plate. The relative position of the connecting plate and the feeding plate in the Y-axis can be adjusted by bolts to adapt to wooden strips of different widths. One side of each of the two connecting plates facing away from each other is connected to an extrusion block. An inclined surface one is provided on the front side of the lower part of the limiting block, and an inclined surface two is provided on the rear side of the lower part of the limiting block.

Adjust the relative position of the extrusion block and the feeding plate by bolts. Control the electric slide rail two to adjust the position of the blocking block in the Y-axis, and then holes can be punched in wooden strips of different specifications. The adjustment is convenient, the adaptability is good, and the practicability is high. Description of the Drawings

Detailed implementation manners

[0028] The following further describes the present invention in detail in conjunction with the accompanying drawings and specific implementation manners, but does not limit the protection scope and application scope of the present invention.

[0029] Example 1: An automatic punching device for wooden strips used in furniture production, as Figures 1 - 11As shown in the figure, it includes a workbench 1, a support plate 2, a surface electric punching head 3, an end electric punching head 4, a control mechanism, a moving frame 5, a lifting plate 6, a limiting plate 7, an adjusting mechanism, a first electric slide rail 8, a feeding plate 9, a triangular block 10, a limiting block 11, a fixing plate 110 and an extrusion mechanism. A support plate 2 is welded to the rear of the workbench 1. A row of surface electric punching heads 3 are arranged on the upper part of the front side of the support plate 2, and a pair of end electric punching heads 4 are arranged on the lower part of the front side of the support plate 2. A control mechanism for controlling the movement of the surface electric punching head 3 and the end electric punching head 4 is arranged on the support plate 2; Two moving frames 5 that move in the X-axis direction are arranged on the top of the workbench 1. A lifting plate 6 that moves in the Z-axis direction is slidably connected to the rear of each moving frame 5, and a limiting plate 7 that moves in the Y-axis direction is slidably connected to the middle of each moving frame 5; A discharge port 60 is formed between the bottom end of the lifting plate 6 and the moving frame 5. When the lifting plate 6 moves in the Z-axis direction, the size of the discharge port 60 is different, so as to adapt to the discharge of single wooden strips 20 with different thicknesses through the discharge port 60; A feeding groove for placing the wooden strips 20 to be punched is formed between the lifting plate 6 and the limiting plate 7; The positions of the moving frame 5, the lifting plate 6 and the limiting plate 7 are adjusted through the adjusting mechanism, so as to adapt to wooden strips 20 of different specifications; Two first electric slide rails 8 that move in the X-axis direction are installed on the top of the workbench 1. Feeding plates 9 that move in the Y-axis direction are installed on the first electric slide rails 8. Two pairs of triangular blocks 10 for pushing the wooden strips 20 are slidably connected to the feeding plates 9. A discharge port 21 is formed between the rear of the workbench 1 and the lower part of the support plate 2. The triangular blocks 10 push the punched wooden strips 20 towards the discharge port 21 for discharging; Limiting blocks 11 that move in the X-axis direction are slidably connected to the fixing plates 110 connected to the mutually remote sides of the two first electric slide rails 8. Right-angle parts 111 are arranged on the upper parts of the limiting blocks 11. The wooden strips 20 being punched are limited by the right-angle parts 111; The triangular blocks 10 and the limiting blocks 11 are reset by return springs. After punching is completed, the limiting blocks 11 are loosened from the wooden strips 20 through the extrusion mechanism.

[0030] As Figures 2 - 5 shown, the control mechanism includes a three-axis control platform one 31 and a three-axis control platform two 41. A three-axis control platform one 31 and a three-axis control platform two 41 are installed on the front side of the support plate 2. The surface electric punching head 3 is installed on the three-axis control platform one 31, and the end electric punching head 4 is installed on the three-axis control platform two 41.

[0031] As Figure 1 , Figure 6 and Figure 7As shown in the figure, the adjusting mechanism includes a guide rail 51, a bidirectional lead screw 52, a gear 61, a rack 62, a knob 71, a screw rod 72 and a nut 73. A guide rail 51 is welded to the front side of the top of the workbench 1. A bidirectional lead screw 52 is rotatably connected to the guide rail 51. The moving frames 5 are all threadedly connected to the bidirectional lead screw 52. When the bidirectional lead screw 52 rotates, the two moving frames 5 move in opposite directions. Gears 61 are rotatably connected to the rear sides of the moving frames 5. Racks 62 meshing with the gears 61 are welded to the lifting plates 6. Screw rods 72 are rotatably connected to the middle parts of the moving frames 5. Knobs 71 are fixedly connected to the ends of the screw rods 72. Nuts 73 threadedly connected to the screw rods 72 are connected to the middle parts of the limiting plates 7.

[0032] As Figure 8 and Figure 9 shown in the figure, the extrusion mechanism includes a connecting plate 121, a bolt 122 and an extrusion block 123. Connecting plates 121 are connected to the mutually remote sides of the two feeding plates 9 through bolts 122. A row of mounting holes are formed in the connecting plates 121. The relative positions of the connecting plates 121 and the feeding plates 9 in the Y-axis direction can be adjusted through the bolts 122 so as to adapt to wooden strips 20 of different widths. Extrusion blocks 123 are fixedly connected to the mutually remote sides of the two connecting plates 121. A first inclined surface 124 is provided on the front side of the lower part of the limiting block 11, and a second inclined surface 125 is provided on the rear side of the lower part of the limiting block 11. After the wooden strip 20 is drilled, the moving-back extrusion block 123 extrudes the first inclined surface 124, and the limiting block 11 can be loosened from the wooden strip 20. After the wooden strip 20 is unloaded, the moving-forward extrusion block 123 extrudes the second inclined surface 125, and the extrusion block 123 can cross over the limiting block 11.

[0033] As Figure 2 、 Figure 3 、 Figure 8 and Figure 11 shown in the figure, a limiting mechanism is further included. The limiting mechanism includes an electric slide rail two 131, a moving block 132 and a stop block 133. An electric slide rail two 131 is connected to the middle of the top of the workbench 1. A moving block 132 is installed on the electric slide rail two 131. A stop block 133 is slidably connected to the moving block 132. A compression spring is fixedly connected between the stop block 133 and the moving block 132. The upper part of the stop block 133 is in a right trapezoid shape.

[0034] The length of the wooden strip 20 in the X-axis direction is the length of the wooden strip 20. The length of the wooden strip 20 in the Y-axis direction is the width of the wooden strip 20. The length of the wooden strip 20 in the Z-axis direction is the thickness of the wooden strip 20. Initially, vertically stacked wooden strips 20 to be drilled are placed in the feeding groove between the lifting plate 6 and the limiting plate 7. The two pairs of triangular blocks 10 at the front side are in a group, and the two pairs of triangular blocks 10 at the rear side are in a group. There is already a wooden strip 20 behind each of the two groups of triangular blocks 10. Among them, the wooden strip 20 located at the rear side has been drilled. The extrusion block 123 has pushed open the limiting block 11, and the reset spring on the limiting block 11 is in a compressed state.

[0035] First step, control the electric slide rail 1 to drive the feeding plate 9 to move backward on the Y-axis. The triangular block 10, the connecting plate 121 and the extrusion block 123 move backward together with the feeding plate 9. The triangular block 10 pushes the two wooden strips 20 to move backward. After the moving extrusion block 123 crosses the limit block 11, under the action of the return spring, the two limit blocks 11 approach each other in the X-axis direction. After the front wooden strip 20 crosses the stop block 133 to the rear of the stop block 133, the front wooden strip 20 will move to the position of the right-angle part 111. The rear wooden strip 20 moves above the discharge port 21. The right-angle part 111 of the two limit blocks 11 limits the rear side and the left and right sides of the front wooden strip 20, and a set of triangular blocks 10 at the rear limits the front side of the front wooden strip 20, so that the position of the front wooden strip 20 is fixed in the horizontal direction.

[0036] Second step, control the surface electric punching head 3 to move in the three-axis direction through the three-axis control platform 1, so as to control the surface electric punching head 3 to punch the surface of the front wooden strip 20; control the end electric punching head 4 to move in the three-axis direction through the three-axis control platform 2, so as to control the end electric punching head 4 to punch the end of the front wooden strip 20, and the control of the punching position is more flexible.

[0037] Third step, after the punching of the front wooden strip 20 is completed, control the electric slide rail 1 to drive the feeding plate 9 to move forward on the Y-axis. The triangular block 10, the connecting plate 121 and the extrusion block 123 move forward together with the feeding plate 9. The moving extrusion block 123 will cross to the front of the limit block 11 through the second extrusion slope 125; the front wooden strip 20 will be blocked by the rear side of the stop block 133 and will not move forward. With the cooperation of the return spring, a set of triangular blocks 10 at the rear cross the front wooden strip 20; and the rear wooden strip 20 is blocked by the rear side surfaces of the two limit blocks 11 and will not move forward, so that the rear wooden strip 20 is separated from the connecting plate 121, and the rear wooden strip 20 falls through the discharge port 21 for discharging; when a set of triangular blocks 10 at the front contacts the lowest wooden strip 20 in the feeding groove, this set of triangular blocks 10 is extruded, and with the cooperation of the return spring, this set of triangular blocks 10 crosses the wooden strip 20 in the feeding groove.

[0038] Step 4: Control the electric slide rail 1 to drive the feeding plate 9 to move backward on the Y-axis. The triangular blocks 10, the connecting plate 121, and the extrusion block 123 move backward together with the feeding plate 9. The front set of triangular blocks 10 push the lowermost wooden strip 20 in the feeding groove to move backward together. When the backward-moving extrusion block 123 contacts the limit block 11, the extrusion block 123 makes the two limit blocks 11 move away from each other on the X-axis through the first extrusion inclined surface 124. The rear set of triangular blocks 10 then push the drilled wooden strip 20 to move backward to leave the limit block 11. At this time, perform the operation of the first step again, and the next wooden strip 20 can be automatically loaded, drilled, and unloaded. The degree of automation is high, and the wooden strip 20 being drilled is limited by the right-angle part 111 and the triangular block 10, with good limiting effect and avoiding displacement of the wooden strip 20.

[0039] Step 5: When drilling wooden strips 20 of different specifications, manually use a tool to rotate the bidirectional lead screw 52. Under the action of the thread, the two moving frames 5 move closer to or away from each other on the X-axis. The lifting plate 6 and the limit plate 7 move together with the moving frames 5 on the X-axis so that the distance between the two feeding grooves on the X-axis adapts to the length of the wooden strip 20. Manually rotate the gear 61, and through meshing, the rack 62 and the lifting plate 6 move up and down on the Z-axis to adjust the size of the discharge port 60 to adapt to the thickness of the wooden strip 20. Then manually rotate the knob 71, and the knob 71 drives the screw 72 to rotate. Through the meshing of the screw 72 and the nut 73, the nut 73 and the limit plate 7 move back and forth on the Y-axis, so that the distance between the lifting plate 6 and the limit plate 7 adapts to the width of the wooden strip 20. At this time, wooden strips 20 of different specifications can be placed in the feeding grooves.

[0040] Step 6: Control the two electric slide rails 1 to move closer to or away from each other in the X-axis direction. The electric slide rails 1 will drive the feeding plate 9, the connecting plate 121, the fixing plate 110, and the limit block 11 to move together on the X-axis, so that the distance between the two right-angle parts 111 when the return spring on the limit block 11 is in the natural state can adapt to the length of the wooden strip 20. Manually turn the bolt 122 to make the bolt 122 pass through the mounting holes at different positions, and adjust the relative position of the connecting plate 121 and the feeding plate 9 on the Y-axis, thereby adjusting the relative position of the extrusion block 123 and the feeding plate 9 on the Y-axis. Control the electric slide rail 2 to drive the moving block 132 and the stop block 133 to move on the Y-axis so that the positions of the extrusion block 123 and the stop block 133 adapt to the width of the wooden strip 20. At this time, wooden strips 20 of different specifications can be drilled, with convenient adjustment, good adaptability, and high practicality.

[0041] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
