Description

Technical Field

[0001] This invention relates to a wood processing equipment, and more specifically, to an automatic toothing and gluing equipment for solid square timber. Background Technology

[0002] Currently, a large amount of waste wood is generated during construction, including many solid square timbers. These solid square timbers are basically scraps from cutting, and due to their varying lengths and short lengths, they cannot be directly reused. Discarding them would result in significant waste. Therefore, to avoid waste, it is necessary to recycle the waste solid square timbers. The conventional recycling method in existing technology is as follows: the two ends of the solid square timbers are cut flat and serrated. Then, glue is applied to the serrated ends of the solid square timbers. Finally, multiple short solid square timbers are spliced ​​end to end using the serrations to form solid square timber strips of usable length. This recycling method allows the waste solid square timbers to be fully utilized, avoiding waste and saving costs.

[0003] However, the existing square timber toothing equipment requires manual feeding and manual alignment of the cutting surfaces. After toothing one end of the square timber, the toothed timber needs to be collected and the above operation is repeated manually to tooth the other end of the square timber. After toothing both ends of the square timber, glue needs to be applied to the toothed areas to facilitate the next splicing process. Therefore, the existing square timber toothing equipment has problems such as low automation, low work efficiency and high labor costs. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides an automatic toothing and gluing device for solid square timber. This device can automatically feed waste square timber, automatically align the end faces, automatically cut the teeth on both end faces, and automatically apply glue to the teeth.

[0005] This invention is achieved using the following technical solution: An automatic toothing and gluing device for solid square timber includes two toothing mechanisms arranged one in front of the other. The front toothing mechanism is connected to the tail end of a feeding mechanism, and the tail end of the front toothing mechanism and the head end of the rear toothing mechanism are respectively connected to the head and tail ends of another feeding mechanism.

[0012] The lifting frame has an opening slot at its front end, and a connecting rod is fixed on the glue-applying roller. The connecting rod is locked and fixed in the opening slot by two nuts that are threaded to it.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention realizes the transmission of solid square timber to the tooth-cutting mechanism by setting a feeding mechanism, and aligns one end of the solid square timber during the transmission process.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, an automatic toothing and gluing device for solid square timber includes two toothing mechanisms 2 arranged one in front of the other. The front toothing mechanism 2 is connected to the tail end of a feeding mechanism 1. The tail end of the front toothing mechanism 2 and the head end of the rear toothing mechanism 2 are connected to the head and tail ends of another feeding mechanism 1, respectively. The rear toothing mechanism 2 is equipped with a gluing mechanism 4. The tail end of the rear toothing mechanism 2 is connected to a discharge conveying mechanism 5. The feeding mechanism 1, toothing mechanism 2, gluing mechanism 4 and discharge conveying mechanism 5 are all electrically connected to the control system.

[0025] The feeding mechanism 1 is used to feed the solid square timber to be processed to the cutting mechanism 2, and align the cutting surfaces of the solid square timber during the feeding process; the cutting mechanism 2 is used to cut one end of the solid square timber fed by the feeding mechanism 1, and further cut a sawtooth interface on the cut surface; the gluing mechanism 4 is used to apply glue to the cutting ends cut by the cutting mechanism 2; the control system is used to control the actions of the feeding mechanism 1, the cutting mechanism 2, the gluing mechanism 4 and the discharge conveying mechanism 5. The control system senses the material position by photoelectric sensors set on the feeding mechanism 1, the cutting mechanism 2, the gluing mechanism 4 and the discharge conveying mechanism 5, thereby controlling the above mechanisms to make appropriate actions. The photoelectric sensors are not shown in the figure. The photoelectric sensors and their control methods are existing conventional technologies and will not be described in detail here.

[0026] like Figure 2 As shown, the tooth cutting mechanism 2 includes a tooth cutting frame 21. A slide rail assembly 22 is provided at the top front end of the tooth cutting frame 21. A material conveying table 23 is movably connected above the slide rail assembly 22. A positioning baffle assembly 26 is fixedly provided at the rear side of the slide rail assembly 22. The material conveying table 23 is connected to the slide rail assembly 22 through a walking drive assembly 27. A cutting assembly 25 and a tooth cutting assembly 24 are provided at the top rear end of the tooth cutting frame 21.

[0027] The positioning baffle assembly 26 includes an L-shaped baffle that supports and is fixed to the support. The support is fixed to the rear side of the slide rail assembly 22. The L-shaped baffle can position the solid square timber end face to be processed from the material conveying table 23. The cutting assembly 25 includes a cutting motor and a saw head connected to the output shaft of the cutting motor. When the saw blade in the saw head passes over the end face of the solid square timber, it cuts the end face of the solid square timber flat, preparing it for the next tooth cutting process. The tooth cutting assembly 24 includes a tooth cutting motor and a tooth cutting saw that is driven by the tooth cutting motor. The tooth cutting saw includes a rotating shaft and multiple tooth cutting blades that are fixed parallel to the rotating shaft. The multiple parallel tooth cutting blades cut multiple teeth on the end face of the solid square timber during high-speed rotation.

[0028] As a preferred embodiment, such as Figure 3 As shown, the feeding mechanism 1 includes a feeding frame 11, a conveyor belt assembly A13 connected to the feeding frame 11, a conveyor drive assembly A12 connected to the conveyor belt assembly A13, a baffle frame 14 fixedly installed at the tail end of the feeding frame 11, a baffle cylinder 15 fixedly installed at the top of the baffle frame 14, an alignment baffle 17 fixedly connected to the telescopic rod of the baffle cylinder 15, and a guide rod A16 fixedly connected to the alignment baffle 17 to maintain the stability of the alignment baffle 17 during the lifting process, and the guide rod A16 is movably connected to the baffle frame 14.

[0029] As a preferred embodiment, such as Figure 4As shown, the material conveying platform 23 includes a material frame 231, a conveyor belt assembly B232 is movably connected to the material frame 231, the conveyor belt assembly B232 is driven by a conveying drive assembly B233, a pressure frame 234 is fixedly provided at the rear end of the material frame 231, an upper pressure cylinder 235 is fixedly provided at the top of the pressure frame 234, and a side pressure cylinder 238 is fixedly provided on the side of the pressure frame 234. An upper pressure plate 237 and a side pressure plate 239 are respectively fixedly connected to the telescopic rods of the upper pressure cylinder 235 and the side pressure cylinder 238. In order to maintain the stability of the upper pressure plate during the lifting process, a guide rod B236 is fixedly connected to the upper pressure plate. The guide rod B236 is movably connected to the pressure plate frame 237, and the material frame 231 is driven by a walking drive assembly 27.

[0030] During operation, the feeding mechanism 1 transports multiple solid square timbers with one end aligned to the conveyor belt assembly B232. Driven by the conveyor drive assembly B233, the conveyor belt assembly B232 transports the solid square timbers to the tail end. At this time, the end face of the solid square timbers contacts the positioning baffle assembly 26 to achieve position positioning. The control system receives the photoelectric sensor signal to control the conveyor drive assembly B233 to stop, and controls the extension rods of the upper pressing cylinder 235 and the side pressing cylinder 238 to extend, thereby driving the upper pressing plate 237 and the side pressing plate 239 to press on the top and side of the solid square timbers respectively, so that the multiple solid square timbers are tightly attached and fixed. Then, the traveling drive assembly 27 drives the material conveying table 23 to move along the slide rail assembly 22.

[0031] Further, such as Figure 5 As shown, the walking drive assembly 27 includes a walking motor 271, a gear 272 and a rack 273. The walking motor 271 is fixedly mounted on the bottom of the material carrier 231, the gear 272 is fixed on the output shaft of the walking motor 271, and the rack 273 is fixed on the slide rail assembly 22. The gear 272 and the rack 273 are meshed and connected.

[0032] As a preferred embodiment, such as Figure 6 As shown, the front cutting mechanism 2 has a pushing mechanism 3 at its tail end. The pushing mechanism 3 includes a pushing bracket 31, a pushing cylinder 32 is fixedly mounted on the pushing bracket 31, and a pushing plate 33 is fixedly connected to the telescopic rod of the pushing cylinder 32.

[0033] The pushing mechanism 3 is used to completely feed the protruding part of the solid square timber after being cut by the front cutting mechanism 2 onto the conveyor belt assembly B232, so that the conveyor belt assembly B232 can convey materials to the next feeding mechanism 1. During operation, the material conveying platform 23 carrying the solid square timber moves to the end of the cutting mechanism 2 and stops. The control system receives the signal and controls the extension rod of the pushing cylinder 32 to move. The extension rod drives the pushing plate 33 to completely push the part of the solid square timber protruding from the conveyor belt assembly B232 onto the conveyor belt assembly B232.

[0034] As a preferred embodiment, such as Figure 6 , Figure 7 As shown, in order to limit the displacement of the material conveying platform 23 at both ends of the track assembly, limit blocks 28 are respectively provided at both ends of the slide rail assembly 22.

[0035] As a preferred embodiment, such as Figure 7 , Figure 8 As shown, the glue application mechanism 4 includes a glue application frame 41, a glue application cylinder 42 fixedly mounted on the glue application frame 41, a lifting frame 43 movably connected to the glue application frame 41 via a slide rail, a glue application roller 44 mounted on the lifting frame 43, a glue bucket 45 located below the glue application roller 44, and the telescopic rod of the glue application cylinder 42 fixedly connected to the lifting frame 43.

[0036] During operation, the telescopic rod of the glue-applying cylinder 42 extends downward, causing the glue-applying roller 44 to be immersed in the glue bucket 45, so that the glue-applying roller 44 is coated with glue. Then, the telescopic rod of the glue-applying cylinder 42 retracts upward, causing the glue-applying roller 44 to rise. When the solid square wood passes through the glue-applying roller 44, its cutting teeth contact the outer surface of the glue-applying roller 44 and are coated with glue, thus completing the glue-applying process.

[0037] Furthermore, the lifting frame 43 has an opening slot 48 at its front end, and a connecting rod 46 is fixed on the glue roller 44. The connecting rod 46 is locked and fixed in the opening slot 48 by two nuts 47 that are threadedly connected to it.

[0038] By adjusting the fixed position of the connecting rod 46 in the opening slot 48 by adjusting the nut 47, the front and rear position of the glue roller 44 can be adjusted. In turn, by adjusting the front and rear position of the glue roller 44, the amount of glue applied when the cutting teeth of the solid square timber come into contact with the glue roller 44 can be adjusted.

[0039] The working process of this invention is as follows: First, multiple solid square timbers are manually stacked side by side and placed vertically on the conveyor belt assembly A13 of the feeding mechanism 1. Driven by the conveyor drive assembly A12, the conveyor belt assembly A13 transports the solid square timbers forward. At this time, the extension rod of the baffle cylinder 15 is extended, and the alignment baffle 17 is lowered to the bottom. The multiple solid square timbers are blocked by the alignment baffle 17, aligning one end of each timber. When the material conveying platform 23 of the front cutting mechanism 2 moves to align with the feeding mechanism 1, the baffle cylinder 15 actuates, raising the alignment baffle 17. The feeding mechanism 1 then feeds the aligned solid square timbers into the material conveying platform. The conveyor platform 23, driven by the conveyor drive assembly B233, transports the aligned solid square timbers to the positioning baffle assembly 26 for toothed end positioning. The control system receives a photoelectric sensor signal to stop the conveyor drive assembly B233 and extends the telescopic rods of the upper pressing cylinder 235 and the side pressing cylinder 238, causing the upper pressing plate 237 and the side pressing plate 239 to press against the top and sides of the multiple solid square timbers, making the multiple solid square timbers tightly fitted and fixed. Then, the travel drive assembly 27 drives the material conveyor platform 23 to move along the slide rail assembly 22. During the movement of the material conveyor platform 23, it passes through... The cutting component 25 and the toothed component 24 are used. The cutting component 25 cuts the end face of the solid square timber, making the end face neat and smooth. The toothed component 24 tooths the end face of the cut solid square timber. When the material conveying table 23 moves to the tail of the slide rail assembly 22, it stops moving. The upper pressure plate 237 and the side pressure plate 239 are retracted. At this time, the pushing mechanism 3 moves to push the solid square timber, which has been toothed by the front toothed component 2, completely onto the conveyor belt assembly B232. The conveyor belt assembly B232, driven by the conveyor drive assembly B233, sends the toothed solid square timber to the next loading mechanism 1. The next loading mechanism 1 repeats the above actions. The solid square timber is conveyed to the tooth-cutting mechanism 2 at the rear, and the other end of the solid square timber that is not toothed is aligned. Then the solid square timber repeats the above actions on the tooth-cutting mechanism 2 at the rear to cut and tooth the other end that is not toothed. After the toothing is completed, the toothed end of the solid square timber passes through the glue-applying device, which applies glue to the tooth. After the glue is applied, the material conveying table 23 moves to the end of the slide rail assembly 22 and stops. The conveyor belt assembly B232, driven by the conveyor drive assembly B233, sends the glued solid square timber into the discharge conveying mechanism 5. The discharge conveying mechanism 5 sends the glued solid square timber to the next station for splicing.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
