Description

Technical Field

[0001] This invention relates to the field of wood cutting auxiliary devices, and particularly to a cutting auxiliary device for furniture production. Background Technology

[0002] Currently, vertical band saws used in furniture manufacturing mostly rely on operators to manually push and cut the wood. This not only poses a safety hazard of cutting hands near the high-speed rotating saw blade, but also makes the cut material easily thrown away by the impact of the rotating saw blade. If the wood needs to be flipped over for secondary cutting or further processing, it must be manually picked up from the saw table area. During this process, the hands still need to frequently approach the dangerous area of ​​the saw blade, which increases the risk of burns, cuts, and collisions, and also reduces production efficiency. It is difficult to meet the needs of efficient, safe, and high-precision continuous operation in furniture production. Summary of the Invention

[0003] The main objective of this invention is to provide a cutting auxiliary device for furniture production, which can effectively solve the problems in the prior art.

Pressure rollers are slidably disposed on the rear side of each set of transmission rods near the positioning bolts. Several cavities are formed inside each pressure roller. Telescopic blocks are movably disposed inside each of the cavities. Spiral patterns are formed on the outer walls of each telescopic block. A movable cavity is formed inside each telescopic block. A second spring is fixedly disposed on the inner wall of the movable cavity. A buckle plate is fixedly disposed at one end of the second spring. A connecting sleeve is fixedly disposed at the front end of the pressure roller. Several square grooves are formed on the outer side of each transmission rod. Protrusions are fixedly disposed on the inner side of each of the square grooves near the connecting sleeve. A cylinder is fixedly disposed at the front end of the movable plate. A pull rod is fixedly disposed behind the cylinder telescopic rod. A sleeve frame is movably disposed behind the pull rod.

[0006] Preferably, the inner side of the pressure roller is provided with several sets of sliding grooves, and a slider is movably arranged on the inner side of each set of sliding grooves. A limit piece is fixedly arranged at the front end of each set of sliders, and a first spring is fixedly arranged between each set of sliders and the inner wall of the corresponding sliding groove.

[0007] Preferably, the saw table has an opening on its inner side, a bushing is fixedly installed at the lower end of the saw table, a U-shaped frame is fixedly installed at the front end of the saw table support, a lead screw is movably installed on the inner side of the bushing and the U-shaped frame, a handwheel is fixedly installed at the front end of the lead screw, a threaded sleeve is threadedly connected to the outer side of the handwheel corresponding to the opening, a baffle is fixedly installed on the upper side of the threaded sleeve, a cover plate is fixedly installed on the upper end of the baffle, and a needle roller is movably installed on the inner side of the baffle.

[0008] Preferably, the saw table has a notch at the position corresponding to the movable plate, the movable plate is slidably disposed in the notch, the two sets of transmission rods are respectively disposed on both sides of the saw blade of the saw, and the two sets of gears are meshed.

[0009] Preferably, the adjusting wheel, pressure wheel, and pressure roller are pressed against the upper end of the wood, the positioning bolt passes through the transmission rod and rests on the adjusting rod, several sets of telescopic blocks are respectively inserted into the inner side of several sets of square slots, the telescopic blocks pass through the bottom of the spiral pattern to the transmission rod, the several sets of spiral patterns are spiral in shape on the outer side of the several sets of telescopic blocks, the spiral pattern is a friction rubber strip, the buckle plate is engaged at the bottom of the cavity, the connecting sleeve is fixed to the pressure roller by bolts, the convex strip is trapezoidal, and the pull rod is respectively sleeved on two sets of connecting sleeves.

[0010] Preferably, the slider is slidably disposed in the groove, the limiting piece corresponds to the cutting position of the saw blade, and the first spring is in a compressed state.

[0011] Preferably, the threaded sleeve passes through the inside of the movable opening, the cover plate is fixed to the baffle by bolts, and several groups of needle rollers are arranged horizontally and evenly.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The handwheel drives the lead screw to rotate, which in turn drives the threaded sleeve and the connected baffle to adjust their positions along the movable opening to determine the location where the wood needs to be cut. At the same time, the use of several sets of needle rollers promotes the close movement of the wood during cutting and reduces resistance.

[0013] The hydraulic cylinder drives the fixed sleeve and movable plate to move up and down, thereby pressing the drive mechanism against the upper end of the wood. Then, the motor drives the connected gears to rotate, which in turn drives the meshing gears and a set of synchronous pulleys to rotate. In conjunction with the synchronous belt, the synchronous belt drives another set of synchronous pulleys to rotate, so that the two sets of transmission rods drive the drive mechanism to rotate simultaneously. This causes the pressed wood to move to one side to facilitate the cutting process and reduce hand injury. The reverse rotation of the drive mechanism will drive the two cut pieces of wood to move back, realizing automatic return work, which is convenient for users to pick up during secondary processing and improves safety.

[0014] When the cut wood is transported back to its original position, the limiting plate unfolds under the elastic force of the first spring because the position of the limiting plate corresponds to the position of the saw blade. This restricts the position of the cut wood between the baffle and the limiting plate during transport, preventing the wood from shifting and coming into contact with the saw blade during the return transport.

[0015] After loosening the two sets of positioning bolts, the control rod can drive the two sets of adjusting wheels to move, controlling the distance between the adjusting wheels and the pressure roller for adjusting the width of the cut wood. Then, tighten the two sets of positioning bolts and the adjusting rod to fix them. The cylinder pulls the pull rod and the sleeve frame to move forward, causing the two sets of connecting sleeves and the pressure roller to slide along the two sets of transmission rods. This allows the telescopic blocks in the pressure roller to slide in the square groove. When they move to the position of the convex strip, they will lift the telescopic blocks and stretch the second spring. This causes the spiral patterns on the outer side of several sets of telescopic blocks to contact another piece of wood after cutting. Thus, when driving the wood to move back, the spiral patterns cause the wood to move away from the saw blade during the back movement, avoiding contact with the saw blade and improving overall safety when quickly moving the wood back.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship as a relative relationship of orientation or position, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0020] Please see Figure 1-10An embodiment of the present invention provides a cutting auxiliary device for furniture production, including a sawing machine 1, a saw table 2 fixedly installed in the middle of the sawing machine 1, a piece of wood 3 placed on the upper end of the saw table 2, a control mechanism 4 installed on the saw table 2, a drive mechanism 5 installed on the control mechanism 4, the control mechanism 4 including a hydraulic cylinder 41 fixedly installed at the front end of the support of the saw table 2, a fixed sleeve 42 fixedly installed on the upper side of the telescopic rod of the hydraulic cylinder 41, a movable plate 43 fixedly installed at the rear end of the fixed sleeve 42, two sets of transmission rods 44 rotatably installed inside the movable plate 43, synchronous pulleys 45 rotatably installed on the front side of each of the two sets of transmission rods 44, synchronous belts 46 sleeved on the outer side of the two sets of synchronous pulleys 45, a motor 47 fixedly installed on the upper inner wall of the movable plate 43, and gears 48 fixedly installed on the rotating shaft of the motor 47 and the outer side of each set of transmission rods 44.

[0021] The saw table 2 has a notch at the position corresponding to the movable plate 43. The movable plate 43 is slidably disposed in the notch. Two sets of transmission rods 44 are respectively disposed on both sides of the saw blade of the saw machine 1. Two sets of gears 48 are meshed.

[0022] The hydraulic cylinder 41 drives the fixed sleeve 42 and the movable plate 43 to move up and down, thereby pressing the drive mechanism 5 onto the upper end of the wood 3. Then, the motor 47 drives the connected gear 48 to rotate, which in turn drives the meshing gear 48 and a set of synchronous pulleys 45 to rotate. In conjunction with the synchronous belt 46, it drives another set of synchronous pulleys 45 to rotate, so that the two sets of transmission rods 44 simultaneously drive the drive mechanism 5 to rotate, causing the pressed wood 3 to move to one side to facilitate the cutting work and reduce the risk of injury to the hands. When the drive mechanism 5 rotates in the opposite direction, it drives the two cut pieces of wood to move back, realizing automatic return work, which is convenient for users to pick up during secondary processing and improves safety.

[0023] The drive mechanism 5 includes two sets of adjusting rods 51 slidably disposed in two sets of transmission rods 44. Adjusting wheels 52 are fixedly disposed on the rear side of each set of adjusting rods 51. Control rods 53 are movably disposed on the rear side of each set of adjusting wheels 52. Pressure rollers 54 are fixedly disposed on the rear edge of each set of transmission rods 44. Positioning bolts 55 are threadedly connected to each set of transmission rods 44 near the pressure rollers 54. Pressure rollers 56 are slidably disposed on the rear side of each set of transmission rods 44 near the positioning bolts 55. Several cavities 57 are formed inside the pressure rollers 56. Telescopic blocks 58 are movably disposed inside the cavities 57. The outer walls of the telescopic blocks 58... The upper part is provided with spiral pattern 59, the inner side of the telescopic block 58 is provided with movable cavity 510, the inner wall of movable cavity 510 is fixedly provided with second spring 511, one end of second spring 511 is fixedly provided with buckle plate 512, the front end of pressure roller 56 is fixedly provided with connecting sleeve 513, the outer side of transmission rod 44 is provided with several sets of square grooves 514, the inner side of several sets of square grooves 514 near the position of connecting sleeve 513 is fixedly provided with protrusion 515, the front end of movable plate 43 is fixedly provided with cylinder 516, the rear side of cylinder 516 telescopic rod is fixedly provided with pull rod 517, and the rear side of pull rod 517 is movably provided with sleeve frame 518.

[0024] Adjusting wheel 52, pressure wheel 54, and pressure roller 56 press against the upper end of wood 3 respectively. Positioning bolt 55 passes through transmission rod 44 and abuts against adjusting rod 51. Several sets of telescopic blocks 58 are respectively inserted into the inner side of several sets of square grooves 514. The telescopic blocks 58 pass through the bottom of spiral pattern 59 to the transmission rod 44. Several sets of spiral pattern 59 are spiral in state on the outside of several sets of telescopic blocks 58. Spiral pattern 59 is a friction rubber strip. Buckle plate 512 is engaged at the bottom of cavity 57. Connecting sleeve 513 is fixed to pressure roller 56 by bolts. Protrusion 515 is trapezoidal. Pull rod 517 is respectively sleeved on two sets of connecting sleeves 513.

[0025] After loosening the two sets of positioning bolts 55, the two sets of adjusting wheels 52 can be moved by the control rod 53 to control the distance between the adjusting wheel 52 and the pressure roller 54 for adjusting the width of the cut wood 3. Then, tighten the two sets of positioning bolts 55 and the adjusting rod 51 to fix them. The cylinder 516 pulls the pull rod 517 and the sleeve 518 forward, which drives the two sets of connecting sleeves 513 and the pressure roller 56 to slide along the two sets of transmission rods 44. This causes the telescopic block 58 in the pressure roller 56 to slide in the square groove 514. When it moves to the position of the convex strip 515, it will lift the telescopic block 58 and stretch the second spring 511. This causes the spiral pattern 59 on the outer side of several sets of telescopic blocks 58 to contact the other piece of wood 3 after cutting. Thus, when the wood 3 is driven to move back, the spiral pattern 59 causes the wood 3 to move away from the saw blade at the same time, avoiding contact with the saw blade. This improves the overall safety when the wood 3 is moved back quickly.

[0026] The inner side of the pressure roller 54 is provided with several sets of sliding grooves 541, and the inner side of each set of sliding grooves 541 is movably provided with a slider 542. The front end of each set of sliders 542 is fixedly provided with a limiting piece 543, and a first spring 544 is fixedly provided between each set of sliders 542 and the inner wall of the corresponding sliding groove 541.

[0027] The slider 542 is slidably set in the groove 541, the limiting piece 543 corresponds to the cutting position of the saw blade of the sawing machine 1, and the first spring 544 is in a compressed state.

[0028] When the cut wood 3 is conveyed back to its original position, the limiting plate 543 unfolds under the elastic force of the first spring 544 because the limiting plate 543 corresponds to the position of the saw blade. This restricts the position of the cut wood 3 between the baffle 12 and the limiting plate 543 during conveying, preventing the wood 3 from shifting and contacting the saw blade when it is conveyed back.

[0029] The saw table 2 has an opening 6 on its inner side. A bushing 7 is fixedly installed at the lower end of the saw table 2. A U-shaped frame 8 is fixedly installed at the front end of the saw table 2 support. A lead screw 9 is movably installed inside the bushing 7 and the U-shaped frame 8. A handwheel 10 is fixedly installed at the front end of the lead screw 9. A threaded sleeve 11 is threadedly connected to the outer side of the handwheel 10 at the position corresponding to the opening 6. A baffle 12 is fixedly installed on the upper side of the threaded sleeve 11. A cover plate 13 is fixedly installed at the upper end of the baffle 12. A needle roller 14 is movably installed inside the baffle 12.

[0030] The threaded sleeve 11 passes through the inside of the movable opening 6, the cover plate 13 is fixed to the baffle 12 by bolts, and several sets of needle rollers 14 are evenly arranged laterally.

[0031] The handwheel 10 drives the lead screw 9 to rotate, which in turn drives the threaded sleeve 11 and the connected baffle 12 to adjust their positions along the movable opening 6 to determine the position where the wood 3 needs to be cut. At the same time, the use of several sets of rollers 14 promotes the close movement of the wood 3 during cutting and reduces resistance.

[0032] Working principle: During use, the handwheel 10 drives the lead screw 9 to rotate, which in turn drives the threaded sleeve 11 and the connected baffle 12 to adjust their positions along the movable opening 6 to determine the cutting position of the wood 3. At the same time, the use of several sets of needle rollers 14 promotes the close movement of the wood 3 during cutting and reduces resistance. The hydraulic cylinder 41 drives the fixed sleeve 42 and the movable plate 43 to move up and down, thereby pressing the drive mechanism 5 against the upper end of the wood 3. Then, the motor 47 drives the connected gear 48 to rotate, which in turn drives the meshing gear 48 and a set of synchronous pulleys 45 to rotate. The synchronous belt 46 drives another set of synchronous pulleys 45 to rotate, so that the two sets of transmission rods 44 simultaneously drive the drive mechanism 5 to rotate, causing the pressed wood 3 to move to one side to promote the cutting work and reduce the risk of injury to the hands. Reverse rotation of the drive mechanism 5 will drive the two cut pieces of board to move back, realizing automatic return work, which is convenient for users to pick up during secondary processing and improves safety. In addition, when conveying the cut wood 3 back to its original position, since the position of the limiting plate 543 corresponds to the position of the saw blade, the limiting plate 543 first Under the elastic force of spring 544, the cut wood 3 is unfolded, restricting its position between the baffle 12 and the limiting plate 543 for conveying, preventing the wood 3 from shifting and contacting the saw blade during reversal. Next, after loosening the two sets of positioning bolts 55, the control rod 53 can move the two sets of adjusting wheels 52, controlling the distance between the adjusting wheels 52 and the pressure roller 54 to adjust the width of the cut wood 3. Then, the two sets of positioning bolts 55 are tightened to fix the adjusting rod 51, while the cylinder 516 pulls the pull rod 517 and the sleeve 518 forward, moving the two sets of... The connecting sleeve 513 and the pressure roller 56 slide along the two sets of transmission rods 44, causing the telescopic block 58 in the pressure roller 56 to slide in the square groove 514. When it moves to the position of the convex strip 515, it will lift the telescopic block 58 and stretch the second spring 511 at the same time, so that the spiral pattern 59 on the outer side of several sets of telescopic blocks 58 contacts the other piece of wood 3 after cutting. Thus, when the wood 3 is driven to move back, the spiral pattern 59 will cause the wood 3 to move away from the saw blade at the same time, avoiding contact with the saw blade. This improves the overall safety when the wood 3 is moved back quickly.

[0033] In this invention, the electrical equipment of the sawing machine 1, hydraulic cylinder 41, motor 47, and cylinder 516 are used in combination with existing components, and the connection and usage methods are common knowledge in the field. Their working principle is a known technology, and the appropriate model is selected according to actual use, so it will not be explained in detail.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
