Description

Technical Field

[0001] The invention relates to the technical field related to wood processing, and in particular to a mechanism for conveying a wood board profile by a woodworking material feeder and grooving the profile. Background Art

[0002] Furniture is an indispensable tool for people to maintain their normal life and engage in production activities. Wooden furniture is widely used because of its light structure and various styles. With the advancement of materials and production technology, modern furniture has developed into a disassembly and assembly form with boards as the basic structure, that is, panel furniture. In the production process of panel furniture, it is necessary to groove the surface of some boards. The manual grooving method using a manual cutting knife is not only inefficient, but the quality of the grooving is affected by the operation level and cannot be guaranteed, and there are also safety hazards. The woodworking feeder is a device for conveying wood for planing or cutting. The feeder uses the feeder wheel of the feeder to press and position the board and push the feed smoothly. The dedicated grooving machine has a frame, and there are a conveying platform and a grooving knife on the frame. The conveying platform conveys the board, and the grooving knife rotates to groove the board. The dedicated grooving machine not only needs to increase the production input cost, but also the conveying function is repeated with the feeder, resulting in waste. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a mechanism for grooving using a woodworking feeder, which achieves the purpose of automatically grooving without adding conveying equipment, reducing production costs, improving production efficiency, and eliminating safety hazards.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a mechanism for slotting using a woodworking material feeder, which includes a workbench, a slotting knife, and a guide strip fixed to the side of the workbench. A material feeder is arranged above the workbench, and the central axis of the feed wheel of the material feeder is perpendicular to the guide strip. The lower end of the material feeder is connected to a shell with an open end, and the open end of the shell corresponds to the end face of the feed wheel. The shell is provided with a pressure block, a transmission block, and an end pressure block. The pressure block and the end pressure block are plugged into the open end of the shell, and the pressure block is adapted to the position of the slotting knife. The transmission block and the shell are movably connected in a direction perpendicular to the central axis of the feed wheel, and the two ends of the transmission block are respectively pressed with the pressure block and the end pressure block. The feed wheel presses the wooden board against the workbench surface and transports it, and the slotting knife rotates to slot the wooden board. The end pressure block transmits the rotation amount of the wooden board to the pressure block in advance, provides instantaneous pre-pressure when the wooden board contacts the slotting knife, reduces the cutting impact force of the slotting knife and the wooden board, and improves the smoothness of the slotted opening. The end pressure block, pressure block, and guide strip limit the rotation of the board, so the board will not get stuck in the slotting, no manual intervention is required, and safety hazards are eliminated. When the feeder is not used for slotting, it can be used as other feeding equipment, saving production equipment investment.

[0008] Preferably, a long pressing block groove penetrating the surface is provided on the symmetry axis of the pressing block, the length extension direction of the long pressing block groove is perpendicular to the plane of the pressing block, and the shell is fixed with a pressing block pin shaft inserted into the long pressing block groove; the pressing block can both move and rotate slightly to increase the length of the pressing block, and the pressing block is pressed tightly against the wooden board but will not get stuck.

[0009] Preferably, the end pressure block is provided with an end pressure block long groove which runs through the surface, the length direction of the end pressure block long groove is consistent with the extension direction of the center axis of the feeding wheel, and the shell is fixed with an end pressure block pin which is plugged into the end pressure block long groove; ensuring that the displacement of the end pressure block parallel to the center axis of the feeding wheel is converted into displacement perpendicular to the center axis of the feeding wheel, so that the pressure block can move quickly and immediately limit the rotation of the wooden board.

[0010] Preferably, the conveying block is strip-shaped and is provided with a long conveying groove running through the surface. The length direction of the long conveying groove is perpendicular to the central axis of the feeding wheel.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0027] Embodiment 1:

[0028] like Figure 1-4 As shown, a mechanism for slotting using a woodworking feeder comprises a workbench 9, a slotting knife 8, and a guide strip 7 fixed to the side of the workbench 9. Figure 1 The structure shown is that the slotting knife 8 is located on the side of the workbench 9 and in the middle of the guide strip 7. A material feeder 1 is provided above the workbench 9. The central axis of the feed wheel 11 of the material feeder 1 is perpendicular to the guide strip 7. There is a wooden board 6 between the feed wheel 11 and the workbench 9 surface. The wooden board 6 is a formed board. The upper surface of the wooden board 6 is pressed against the feed wheel 11, and the lower surface is pressed against the workbench 9 surface. One side of the wooden board 6 is in contact with the guide strip 7. The feed wheel 11 rotates, and the wooden board 6 moves on the workbench 9 surface along the extension direction of the guide strip 7.

[0029] The lower end of the material feeder 1 is connected to a shell 2. The shell 2 is a rectangular cavity structure. One end of the shell 2 is open. The open end of the shell 2 is located at the end face of the feeding wheel 11, and the end face is the corresponding face of the end face of the feeding wheel 11 close to the guide bar 7, that is, the opening of the shell 2 faces the guide bar 7. The shell 2 is provided with a pressure block 3, a transmission block 4, and an end pressure block 5. The pressure block 3 and the end pressure block 5 are plugged into the open end of the shell 2. The shell 2 is fixed with an end pressure block pin 21, a transmission pin 22, and a pressure block pin 23. The two ends of the end pressure block pin 21, the transmission pin 22, and the pressure block pin 23 are respectively fixed to the two side surfaces of the opening of the shell 2. The end pressure block pin 21, the transmission pin 22, and the pressure block pin 23 are parallel to each other and perpendicular to the central axis of the feeding wheel 11. Figure 3 The middle workbench 9 is not shown. Figure 4 A half of a symmetrical figure is shown, in which the wooden board 6 and the workbench 9 are not shown.

[0030] The conveying block 4 is in the shape of a strip. One end of the conveying block 4 is provided with an inclined surface, and the other end is provided with an arc surface. The conveying block 4 is provided with a conveying long groove 41. The conveying long groove 41 runs through the surface of the conveying block 4. The length direction of the conveying long groove 41 is perpendicular to the central axis of the feeding wheel 11. The conveying pin 22 is plugged into the conveying long groove 41. One conveying long groove 41 connects two conveying pins 22. There is a spacing between the two conveying pins 22 and between the conveying pin 22 and the end of the conveying long groove 41.

[0031] The pressing block 3 is plate-shaped. The pressing block 3 is a flat surface at one end and an arc surface structure at the other end, that is, the pressing block 3 is a part of a circular plate. The plane of the pressing block 3 is located on the opening side of the shell 2, and the arc surface is located in the cavity of the shell 2. The arc surface of the pressing block 3 is provided with a pressing block guide groove 32. The pressing block guide groove 32 is arranged along the arc surface of the pressing block 3, and is recessed in the surface of the arc surface of the pressing block 3. The outer surface of the groove side of the pressing block guide groove 32 is flush with the surface of the pressing block 3. The groove width of the pressing block guide groove 32 is the same as the thickness of the arc surface of the conveying block 4. The curvature of one end of the arc surface of the conveying block 4 is the same as the curvature of the groove bottom of the pressing block guide groove 32. The pressing block 3 is provided with a pressing block long groove 31. The pressing block long groove 31 runs through the surface of the pressing block 3. The pressing block long groove 31 is located on the symmetry axis of the pressing block 3. The length extension direction of the pressing block long groove 31 is perpendicular to the plane of the pressing block 3. That is, the pressing block long groove 31 is located on the symmetry axis of the pressing block 3. There is one pressing block pin 23 which is plugged into the pressing block long groove 31 .

[0032] The end pressure block 5 is a right-angled trapezoidal plate-like structure. The trapezoidal lower bottom surface of the end pressure block 5 is located on the opening side of the shell 2. The trapezoidal upper bottom surface of the end pressure block 5 is located in the cavity of the shell 2. The angle between the trapezoidal lower bottom surface of the end pressure block 5 and the inclined waist surface is 30°. The trapezoidal inclined waist surface of the end pressure block 5 is provided with an end pressure block guide groove 52. The end pressure block guide groove 52 is recessed in the surface of the trapezoidal inclined waist surface of the end pressure block 5. The outer surface of the groove side of the end pressure block guide groove 52 is flush with the surface of the end pressure block 5. The groove width of the end pressure block guide groove 52 is the same as the thickness of the inclined surface of the conveying block 4. The right-angled waist surface of the end pressure block 5 is close to the inner cavity wall of the end surface of the shell 2 and can be movably connected to the inner cavity wall. The end pressure block 5 is provided with an end pressure block long groove 51. The end pressure block long groove 51 runs through the surface of the end pressure block 5. The length direction of the end pressing block slot 51 is consistent with the extension direction of the central axis of the feeding wheel 11, that is, the length direction of the end pressing block slot 51 is consistent with the height direction of the right angle waist of the right angle trapezoid of the end pressing block 5. The end pressing block pin 21 is plugged into the end pressing block slot 51.

[0033] The pressing block 3 is a single piece. The axis of symmetry of the pressing block 3 coincides with the central axis of the housing 2. The transmission block 4 and the end pressing block 5 are each a pair. The transmission block 4 and the end pressing block 5 are symmetrically arranged with the central axis of the housing 2 as the axis of symmetry. The inclined surface end of the transmission block 4 is embedded in the end pressing block guide groove 52. The arc surface end of the transmission block 4 is embedded in the pressing block guide groove 32.

[0034] During installation, align the symmetry axis of the pressing block 3 with the slotting knife 8 . Figure 3 As shown, the wooden board 6 is pushed along the guide strip 7 by the rotation of the feeding wheel 11. The slotting knife 8 rotates to slot the side of the wooden board 6. When all the feeding wheels 11 press the wooden board 6, the friction between the axial direction of the feeding wheel 11 and the wooden board 6 can prevent the thrust of the slotting knife 8 on the wooden board 6, and the pressing block 3 and the end pressing block 5 are suspended on the side of the wooden board 6. Figure 3 A gap can be seen between the middle pressure block 3 and the side of the wooden board 6.

[0035] When the feeding wheel 11 partially presses the wooden board 6, Figure 5The figure shows the connection structure of the wooden board 6 and the slotting knife 8 just in contact. At this time, the slotting knife 8 has an impact force on the wooden board 6, which is greater than the axial friction force generated by the part of the feeding wheel 11 pressing the wooden board 6, and the wooden board 6 will rotate. This requires intervention, that is, an external force is applied to the side of the wooden board 6. At this time, the contact end of the wooden board 6 and the slotting knife 8 will leave the guide bar 7 (as shown by the double-dotted line in the figure). The side of the rotating wooden board 6 pushes the trapezoidal bottom surface of the end pressure block 5 on the left, and the end pressure block 5 retracts into the shell 2 along the central axis direction of the feeding wheel 11. The conveying block 4 is movably connected to the shell 2 along the direction perpendicular to the central axis of the feeding wheel 11. The inclined surface of the conveying block 4 is pressed against the end pressure block 5. The trapezoidal inclined surface of the end pressure block 5 pushes the conveying block 4 to move. The arc surface of the conveying block 4 is pressed against the end pressure block 5. The arc surface of the conveying block 4 pushes the plane of the pressure block 3 to extend further out of the shell 2. The pressure block 3 presses the corresponding side surface of the contact end of the wooden board 6 and the slotting knife 8, providing the wooden board 6 with a force to resist the thrust of the slotting knife 8 on the wooden board 6. Since the long pressing block groove 31 of the pressing block 3 is plugged into a pressing block pin 23, when the pressing block 3 is thrust by the conveying block 4, the pressing block 3 can extend out of the shell 2 along the axial direction of the feeding wheel 11, and when extended to the limit, it can also deflect, further shortening the distance between the pressing block 3 and the side of the wooden board 6, suppressing the wooden board 6 to rotate, and the wooden board 6 can move smoothly along the direction of the guide strip 7 to ensure the quality of the grooving.

[0036] like Figure 6 As shown, the wooden board 6 is about to be slotted, and at this time the feeding wheel 11 only partially presses the wooden board 6. The impact force of the slotting knife 8 on the wooden board 6 is greater than the axial friction force generated by the partial feeding wheel 11 pressing the wooden board 6, and the wooden board 6 will rotate. The contact end of the wooden board 6 with the slotting knife 8 will leave the guide bar 7 (as shown by the double dotted line in the figure). The side of the rotating wooden board 6 pushes the trapezoidal bottom surface of the end pressure block 5 on the right, and the end pressure block 5 retracts into the shell 2 along the central axis direction of the feeding wheel 11. The conveying block 4 moves, and the arc surface of the conveying block 4 pushes the plane of the pressure block 3 to extend further out of the shell 2, and the pressure block 3 presses the side of the contact end of the wooden board 6 with the slotting knife 8. When the pressure block 3 extends to the limit, it can deflect, further shortening the distance between the pressure block 3 and the side of the wooden board 6, and pressing the wooden board 6 to rotate. The wooden board 6 moves along the direction of the guide bar 7 and smoothly separates from the slotting knife 8, ensuring the quality of the slotting.

[0037] Embodiment 2:

[0038] like Figure 7 , 8 As shown, the slotting knife 8 is located below the feeding wheel 11. During installation, align the symmetry axis of the pressing block 3 with the slotting knife 8. The wooden board 6 is pushed along the guide strip 7 by the rotation of the feeding wheel 11. The slotting knife 8 rotates to slot the lower surface of the wooden board 6. When all the feeding wheels 11 press the wooden board 6, the friction between the axial direction of the feeding wheel 11 and the wooden board 6 can prevent the thrust of the slotting knife 8 on the wooden board 6 parallel to the axial direction of the feeding wheel 11. The pressing block 3 and the end pressing block 5 are suspended on the side of the wooden board 6. Figure 7 A gap can be seen between the middle pressure block 3 and the side of the wooden board 6.

[0039] Fig. 9 The figure shows the connection structure of the part of the feeding wheel 11 pressing the wooden board 6 when the wooden board 6 and the slotting knife 8 just come into contact. At this time, the slotting knife 8 generates an impact component force on the wooden board 6 parallel to the axial direction of the feeding wheel 11, and the impact component force is greater than the axial friction force generated by the part of the feeding wheel 11 pressing the wooden board 6, and the wooden board 6 will rotate. The contact end of the wooden board 6 and the slotting knife 8 will leave the guide bar 7 (as shown by the double dotted line in the figure). The side of the rotating wooden board 6 pushes the trapezoidal bottom surface of the end pressure block 5 on the left, and the end pressure block 5 retracts into the shell 2 along the central axis direction of the feeding wheel 11. The trapezoidal inclined surface of the end pressure block 5 pushes the conveying block 4 to move. The arc surface of the conveying block 4 pushes the plane of the pressure block 3 to extend further out of the shell 2. The pressure block 3 presses the corresponding side surface of the contact end of the wooden board 6 and the slotting knife 8. Since the long pressing block groove 31 of the pressing block 3 is plugged into a pressing block pin 23, when the pressing block 3 is thrust by the conveying block 4, the pressing block 3 can extend out of the shell 2 along the axial direction of the feeding wheel 11, and when extended to the limit, it can also deflect, further shortening the distance between the pressing block 3 and the side of the wooden board 6, suppressing the wooden board 6 to rotate, and the wooden board 6 can move smoothly along the direction of the guide strip 7 to ensure the quality of the grooving.

[0040] like Fig.10 As shown, the wooden board 6 is about to be slotted, and at this time the feeding wheel 11 only partially presses the wooden board 6. The axial friction force generated by the partial feeding wheel 11 pressing the wooden board 6 is smaller than the impact component force of the slotting knife 8 on the wooden board 6 parallel to the axial direction of the feeding wheel 11, and the wooden board 6 will rotate. The contact end of the wooden board 6 and the slotting knife 8 will leave the guide bar 7 (as shown by the double dotted line in the figure). The side of the rotating wooden board 6 pushes the trapezoidal bottom surface of the end pressure block 5 on the right, and the end pressure block 5 retracts into the shell 2 along the central axis of the feeding wheel 11. The conveying block 4 moves, and the arc surface of the conveying block 4 pushes the plane of the pressure block 3 to extend further out of the shell 2, and the pressure block 3 presses the side of the contact end of the wooden board 6 and the slotting knife 8. When the pressure block 3 extends to the limit, it can deflect, further shortening the distance between the pressure block 3 and the side of the wooden board 6, and suppressing the wooden board 6 to rotate. The wooden board 6 moves smoothly along the direction of the guide bar 7 and leaves the slotting knife 8 to ensure the quality of the slotting.
