Description

Technical Field

[0001] This utility model belongs to the technical field of wood processing equipment, and relates to a machine that automatically mills, glues, and splices wood cores into boards. Background Technology

[0002] Solid wood spliced ​​panels are one of the most commonly used materials in the furniture and home decoration industries. They are composed of several strips of square timber, and the production process mainly includes planing, gluing, and splicing. First, workers move the wood cores to the planing area, feeding them one by one into the planing machine to be milled into square timber strips. Then, workers move the strips to the gluing area, feeding them one by one into the gluing machine to apply glue to one side. Finally, workers move the glued strips to the splicing area, feeding them one by one into the splicing machine to assemble them into panels. Each step requires manual handling, resulting in high labor costs, high workload, and low efficiency. Utility Model Content

[0003] This utility model provides an automatic wood core splicing machine to solve the problems of high labor costs, high labor intensity and low work efficiency in the existing solid wood splicing board production methods.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: It includes a feeding machine, a four-sided milling machine, a gluing machine, a panel splicing machine, and a PLC controller. The four-sided milling machine is located between the feeding machine and the gluing machine, and the gluing machine is located between the four-sided milling machine and the panel splicing machine. The feeding machine includes a feeding conveyor belt and a feeding conveyor belt, with a guide rod between the feeding conveyor belt and the feeding conveyor belt. The feeding conveyor belt and the feeding conveyor belt are driven by a feeding hydraulic motor. The feeding conveyor belt extends to the inlet end of the four-sided milling machine. The worker places the wood core on the feeding conveyor belt. On the feeding conveyor belt, the wood core is conveyed along the guide rod to the feeding conveyor belt, and then the wood core is conveyed by the feeding conveyor belt to the inlet end of the four-sided milling machine; the four-sided milling machine includes an inlet roller group, a feeding roller group, and an outlet roller group. The inlet roller group is located at the inlet end of the four-sided milling machine, the outlet roller group is located at the outlet end of the four-sided milling machine, and the feeding roller group is located between the inlet roller group and the outlet roller group. The inlet roller group, the feeding roller group, and the outlet roller group are all driven by a feeding hydraulic motor. A longitudinal milling cutter roller group is provided between the inlet roller group and the feeding roller group. A transverse milling roller group is provided between the feed roller group and the discharge roller group. The longitudinal milling roller group is driven by a longitudinal milling motor, and both transverse milling roller groups are driven by transverse milling motors. The discharge roller group is aligned with the feed inlet of the glue applicator. The feed roller group presses the wood core to the longitudinal milling roller group, which planes the top and bottom of the wood core to obtain a wood strip with flat top and bottom surfaces. This strip is then fed to the feed roller group, which presses the planed wood strip to the transverse milling roller group. The transverse milling roller group planes the left and right sides of the wood strip to obtain a square wood strip, which is then fed to the discharge roller group. The discharge roller assembly then presses the square timber strips into the feed inlet of the glue applicator. The glue applicator includes a glue-holding funnel and a glue-applying roller. A glue outlet is provided on one side of the lower part of the glue-holding funnel. One end of the glue-applying roller extends into the glue outlet, so that one end of the glue-applying roller is immersed in the glue in the glue-holding funnel. When the square timber strip passes through the glue-applying roller, it will rotate. The glue-applying roller end extending into the glue outlet carries out the glue and applies it to one side of the square timber strip. The feed inlet of the glue applicator is aligned with the feed inlet of the splicing machine. The square timber strip with glue applied to one side is pushed to the feed inlet of the splicing machine.The splicing machine includes a photoelectric switch, a lifting cylinder, a lifting pressure platform, a pushing cylinder, and a pushing plate. The photoelectric switch is located at the end of the splicing machine, and the lifting pressure platform is located above the splicing machine. The lifting pressure platform is driven to rise and fall by the lifting cylinder. The pushing plate is located on one side of the splicing machine and is driven to move horizontally by the pushing cylinder. When a square wood strip coated with glue touches the photoelectric switch, the lifting cylinder controls the lifting pressure platform to lightly press down on the square wood strip, and then the pushing cylinder... The pusher plate pushes the un-glued side of the wooden strip, causing it to move a short distance before returning to its original position. When the next wooden strip coated with glue touches the photoelectric switch, the pusher plate repeats this process multiple times, thus completing the splicing of glued wooden strips into a solid wood panel. The feeding hydraulic motor, the longitudinal milling motor, the transverse milling motor, the photoelectric switch, the lifting cylinder, and the pusher cylinder are all connected to a PLC controller.

[0005] A more specific technical solution to the above technical solution is as follows: A saw blade is provided at the feed inlet of the splicing machine. The saw blade is connected to a cutting motor, which is connected to a cutting cylinder. The cutting cylinder is connected to a PLC controller. When the end of the square timber strip coated with glue touches the photoelectric switch, the lifting cylinder controls the lifting pressure table to lightly press on the square timber strip. Then, the cutting motor drives the saw blade to rotate, and the cutting cylinder pushes the saw blade connected to the cutting motor to move towards the square timber strip and cut off a portion of the tail end of the square timber strip. Then, the pushing cylinder pushes the pushing plate towards the side of the square timber strip that is not coated with glue, so that the square timber strip moves a small distance before the pushing plate returns to its original position.

[0006] Furthermore: the transverse milling cutter roller assembly consists of a tenon milling cutter roller and a mortise milling cutter roller. The roller surface of the tenon milling cutter roller is tenon-shaped, and the roller surface of the mortise milling cutter roller is mortise-shaped. The tenon milling cutter roller is used to mill one side of the wood strip into a surface with a tenon, and the mortise milling cutter roller is used to mill the other side of the wood strip into a surface with a mortise. The resulting square wood strip has a tenon on one side and a mortise on the other side.

[0007] Furthermore, the bottom of the lifting pressure platform is provided with a pressure rod, and a return spring is provided between the pressure rod and the lifting pressure platform to prevent damage to the square timber strips.

[0008] Furthermore, the longitudinal milling cutter roller assembly is equipped with an exhaust hood, which is used to remove the wood chips generated by the longitudinal milling cutter roller assembly during milling of the upper and lower surfaces of the wood core.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: After the wood core is fed to the four-sided milling machine by the feeding machine to be milled into square wood strips, the four-sided milling machine feeds the square wood strips to the gluing machine. The gluing rollers apply glue to one side of the square wood strips. The square wood strip with glue on one side is pushed to the splicing machine. After the photoelectric switch is triggered, the lifting pressure table presses lightly on the square wood strip, and the pusher plate pushes the square wood strip back to its position. By repeating the above actions multiple times, the wood core can be automatically milled, glued, and spliced ​​into solid wood splicing boards. There is no need for manual handling, milling, gluing, and splicing, which effectively reduces labor costs, reduces labor intensity, and increases work efficiency. Attached Figure Description

The feeding machine 1 includes a feeding conveyor belt 11 and a feeding conveyor belt 13. A guide rod 12 is provided between the feeding conveyor belt 11 and the feeding conveyor belt 13. The feeding conveyor belt 11 and the feeding conveyor belt 13 are driven by a feeding hydraulic motor. The feeding conveyor belt 13 extends to... The four-sided milling machine includes an infeed roller assembly 21, a feed roller assembly 23, and an outlet roller assembly 25. The infeed roller assembly 21 is located at the infeed end of the four-sided milling machine, and the outlet roller assembly 25 is located at the outlet end. The feed roller assembly 23 is located between the infeed roller assembly 21 and the outlet roller assembly 25. All three rollers are driven by a feeding hydraulic motor. A longitudinal milling cutter roller assembly 22 is located between the infeed roller assembly 21 and the feed roller assembly 23. The feed roller assembly 23 is connected to the outlet roller assembly 25. A transverse milling cutter roller group 24 is provided between the roller groups 25. The longitudinal milling cutter roller group 22 is driven by a longitudinal milling motor, and the transverse milling cutter roller group 24 is driven by a transverse milling motor. The discharge roller group 25 is aligned with the inlet of the glue applicator 3. The glue applicator 3 includes a glue-holding funnel 31 and a glue-applying roller 32. A glue outlet is opened on one side of the lower part of the glue-holding funnel 31, and one end of the glue-applying roller 32 extends into the glue outlet. The inlet of the glue applicator 3 is aligned with the inlet of the panel assembly machine 4. The panel assembly machine 4 includes a photoelectric switch 41 and a lifting cylinder. 42. A lifting pressure table, a pushing cylinder 46, and a pushing plate 47 are located at the end of the panel assembly machine 4. A photoelectric switch 41 is located above the panel assembly machine 4. The lifting pressure table is driven to rise and fall by a lifting cylinder 42. The pushing plate 47 is located on one side of the panel assembly machine 4 and is driven to move horizontally by a pushing cylinder 46. The feeding hydraulic motor, the longitudinal milling motor, the transverse milling motor, the photoelectric switch 41, the lifting cylinder 42, and the pushing cylinder 46 are all connected to a PLC controller. A saw blade 45 is provided at the feed inlet of the panel assembly machine 4. The saw blade 45 is connected to a cutting motor, which is connected to a cutting cylinder, which is connected to the PLC controller. A pressure rod 44 is provided at the bottom of the lifting pressure table, and a return spring is provided between the pressure rod 44 and the lifting pressure table. A ventilation hood is provided under the longitudinal milling cutter roller group 22.

[0019] In operation, the PLC controller controls the feeding hydraulic motor, the longitudinal milling motor, and the transverse milling motor to start working. The worker places the wood core on the feeding conveyor belt 11, and the wood core is transported along the guide rod 12 to the feeding conveyor belt 13. The wood core is then transported by the feeding conveyor belt 13 to the inlet end of the four-sided planer. The inlet roller group 21 presses the wood core to the longitudinal milling cutter roller group 22, which mills the top and bottom of the wood core to obtain wood strips with flat top and bottom, which are then sent to the feeding roller. Group 23, the feeding roller group 23 presses the wood strip, which is flat on both the top and bottom, to the transverse milling roller group 24. The transverse milling roller group 24 planes the wood strip into flat surfaces on both sides, resulting in a square wood strip, which is then fed to the discharge roller group 25. The discharge roller group 25 then presses the square wood strip to the inlet of the glue applicator 3. One end of the glue applicator roller 32 is immersed in the glue in the glue funnel 31. As the square wood strip passes through the glue applicator roller 32, it rotates, and the end of the glue applicator roller 32 extending into the glue outlet carries the glue out and applies it to one side of the square wood strip. The glued timber strip is pushed to the feed inlet of the splicing machine 4. When the end of the glued timber strip touches the photoelectric switch 41, the PLC controller controls the feeding hydraulic motor and the material feeding hydraulic motor to stop working. The PLC controller then controls the lifting cylinder 42 to make the lifting pressure table lightly press on the timber strip. The PLC controller then controls the cutting motor to drive the saw blade 45 to rotate. The PLC controller then controls the cutting cylinder to push the saw blade 45 connected to the cutting motor to move towards the timber strip and lift the end of the timber strip. A portion is cut off and falls off. Then, the PLC controller controls the pusher cylinder 46 to push the pusher plate 47 towards the side of the square wood strip that is not coated with glue. After the square wood strip is moved a short distance, the pusher plate 47 returns to its original position. The PLC controller then controls the feeding hydraulic motor and the material feeding hydraulic motor to continue working. This process is repeated until the next square wood strip coated with glue touches the photoelectric switch 41. The pusher plate 47 repeats this process multiple times, thus automatically milling, gluing, and splicing the wood core into a solid wood spliced ​​board. Figure 4 As shown.

The feeding conveyor belt 11 and the feeding conveyor belt 13 are driven by a feeding hydraulic motor, and the feeding conveyor belt 13 extends to the inlet end of the four-sided milling machine.

In this example, the milling roller group 24, with its tenon milling roller and mortise milling roller, mills both sides of a planar wooden strip into square wooden strips with tenons and mortises. The resulting square wooden strips with tenons and mortises are then fed to the discharge roller group 25, which presses them into the inlet of the glue applicator 3.

As the tenon side of the square wooden strip passes through the glue applicator roller 32, it rotates, and the end of the glue applicator roller 32 extending into the glue outlet carries the glue out and applies it to the square wooden strip.
