Description

Technical Field

[0001] This invention relates to the field of hot pressing molding technology, specifically to a hot pressing molding device for bamboo laminated timber with uniform heating. Background Technology

[0002] Bamboo laminated boards are widely used in furniture manufacturing, building decoration and other fields due to their advantages such as high strength, good environmental protection and renewable resources. In the production of bamboo laminated materials, gluing and hot pressing equipment is often used to prepare plywood and other products.

[0003] As a key pressure-bearing component of the hot pressing device, the surface cleanliness of the hot pressure seat directly determines the molding quality of the bamboo composite board. However, existing hot pressure seats in bamboo composite board hot pressing devices generally lack dedicated surface cleaning devices. During continuous production, foreign matter such as wood chips and impurities adhering to the surface of the bamboo substrate easily fall off and remain on the surface of the hot pressure seat. Due to the lack of an effective cleaning mechanism, these residual wood chips and impurities cannot be removed in time. During subsequent hot pressing operations, under high pressure, the wood chips and impurities are squeezed to the surface of the bamboo composite material, thus forming permanent indentations on the surface of the finished product, which not only seriously affects the appearance of the product. In addition to quality issues, the surface structure integrity of bamboo laminated timber may also be compromised. Furthermore, existing hot pressing equipment does not have corresponding pretreatment mechanisms for the hot pressing characteristics of bamboo laminated timber of different specifications. Especially when processing thick bamboo laminated timber, the hot pressing time for thick bamboo laminated timber is longer, and the amount of glue overflow between bamboo laminated timbers increases significantly. A large amount of overflow glue is easy to solidify and firmly adhere to the surface of the hot pressure seat. These solidified residual glues will cause the surface flatness of the hot pressure seat to decrease during subsequent hot pressing operations. This not only affects the uniform transmission of hot pressing temperature and pressure, but also easily causes the bamboo laminated timber to stick to the hot pressure seat, further deteriorating the hot pressing effect. Summary of the Invention

[0004] The purpose of this invention is to provide a hot-pressing device for uniformly heated bamboo laminated timber, thereby solving the problems mentioned in the background art.

A liquid guiding rod is rotatably connected to both mounting components.

[0006] Preferably, the liquid guiding rod has multiple spraying channels, and each of the spraying channels is fixedly connected to a liquid breaking plate. Fixing members are fixedly connected to the outer walls of the mounting components on both sides, and a liquid storage tank is fixedly connected to each fixing member. The end of the liquid guiding rod rotatably penetrates into the liquid storage tank. A spraying restrictor is provided on the outer wall of the mounting component, and a scraper plate is fixedly connected to the outer wall of the spraying restrictor. Suction pipes are connected to both sides of the bottom of the spraying restrictor, and a miniature suction pump is installed inside each suction pipe. The end of the suction pipe away from the spraying restrictor is connected to the interior of the liquid storage tank.

[0007] Preferably, the liquid guiding rod has a liquid inlet hole at one end inside the liquid storage tank. Limiting rods are fixedly connected to both sides of the liquid guiding rod, and a blocking plug is slidably connected to both limiting rods to block the liquid inlet hole. A return spring is sleeved on the outer wall of the limiting rod. Mounting plates are fixedly connected to both sides of the blocking plug, and a magnetic block is fixedly connected to the end of the mounting plate. Slide rails are provided on both sides of the liquid guiding rod, and a magnetic element is slidably connected inside the slide rail. The magnetic element has the same magnetic pole as the magnetic block. A pressing spring is fixedly connected to the outer wall of the magnetic element, and the other end of the pressing spring is fixedly connected to the inner wall of the slide rail.

[0008] Preferably, a lower gear is sleeved on the outer side wall of both ends of the liquid guiding rod, and a transmission gear is rotatably connected to the outer side wall of the mounting component, wherein the transmission gear and the lower gear are meshed.

[0009] Preferably, the detection mechanism includes a detection box fixedly connected to the outer wall of the mounting box. The detection box has a lower chamber, a sealing chamber and an upper chamber inside. The lower chamber, the sealing chamber and the upper chamber are slidably connected to a plurality of sliding tubes, and each of the plurality of sliding tubes has a through hole.

[0010] Preferably, one end of the plurality of sliding tubes located inside the upper chamber is sealed, and one end of the plurality of sliding tubes located outside the detection box is fixedly connected to a telescopic rod, the other end of which is connected to the outer wall of the detection box.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This equipment features a differentiated surface pretreatment process for the hot pressure seat, designed for both regular batches and thicker sizes of bamboo laminated timber. For regular batches, impurities can be effectively removed by the reciprocating scraping of the scraper. For thicker sizes of bamboo laminated timber with large amounts of excess adhesive and easy curing, a combined treatment method is used, including initial scraping and cleaning, spraying of release agent, and smoothing to form a film. First, impurities on the surface of the hot pressure seat are removed by the scraper, and then a release agent is precisely sprayed and smoothed to form an anti-sticking isolation film. This fundamentally avoids the problem of excess adhesive sticking during curing, significantly improving the equipment's adaptability to different sizes of bamboo laminated timber and ensuring the stability of the subsequent hot pressing effect.

[0015] 2. Before the bamboo laminated timber enters the hot pressing area, this equipment uses a visual detector to accurately detect the bamboo nodes. Based on the size of the nodes, it grades and marks them for targeted treatment. Smaller, uncleaned nodes are marked with red dye to remind operators to focus on sanding after hot pressing to eliminate defects. Larger nodes that affect the hot pressing effect are marked with blue dye, triggering a machine shutdown. This allows operators to promptly replace substandard materials, preventing the hot-pressed product from being scrapped due to large nodes. The detection and grading of bamboo nodes reduces the blind spots in subsequent processes, improves production efficiency, and effectively ensures the forming quality and strength stability of the bamboo laminated board.

[0030] The technical solutions of 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.

[0031] Example 1: Please refer to Figure 1 - Figure 12 A uniformly heated bamboo laminated timber hot-pressing molding device includes a main body 1, a support 5 mounted on the main body 1, multiple hydraulic rods 6 fixedly connected to the outer wall of the support 5, and a hot pressure seat 7 fixedly connected to the ends of the multiple hydraulic rods 6. Electric linear slide rails 4 are fixedly connected to both sides of the support 5, and a mounting box 8 is installed inside the electric linear slide rails 4 on both sides. A vision detector 13 is installed on the outer wall of the mounting box 8 for detecting the size of bamboo joints. The mounting box 8 contains a pre-processing mechanism and a detection mechanism. The pre-processing mechanism includes... A scraper 23 is slidably connected to the mounting box 8. Two sludge collection boxes 24 are installed on the outer wall of the mounting box 8. Upper racks 34 are fixedly connected to both sides of the scraper 23 inside the mounting box 8. A base plate 26 is slidably connected inside the mounting box 8. Lower racks 32 are fixedly connected to both sides of the base plate 26. Two electric drive gears 33 are fixedly connected inside the mounting box 8. The electric drive gears 33 are respectively meshed with the lower racks 32 and the upper racks 34. Mounting parts 27 are fixedly connected to both sides of the base plate 26. A liquid guiding rod 29 is rotatably connected to both mounting parts 27.

[0032] Multiple spraying channels 30 are provided on the liquid guiding rod 29. Each spraying channel 30 is fixedly connected to a liquid breaking plate 31. Fixing members 35 are fixedly connected to the outer walls of the two mounting parts 27. A liquid storage tank 22 is fixedly connected to the fixing members 35. The end of the liquid guiding rod 29 rotates through to the inside of the liquid storage tank 22. A spraying restrictor 25 is provided on the outer wall of the mounting part 27. A scraper plate 28 is fixedly connected to the outer wall of the spraying restrictor 25. Suction pipes 3 are connected to both sides of the bottom of the spraying restrictor 25. A micro suction pump is provided inside the suction pipe 3. The end of the suction pipe 3 away from the spraying restrictor 25 is connected to the inside of the liquid storage tank 22.

[0033] The liquid guiding rod 29 has an inlet hole 38 at one end inside the liquid storage tank 22. Limiting rods 40 are fixedly connected to both sides of the liquid guiding rod 29. A blocking plug 39 is slidably connected to both limiting rods 40, blocking the inlet hole 38. A return spring 41 is sleeved on the outer wall of the limiting rod 40. Mounting plates 42 are fixedly connected to both sides of the blocking plug 39. A magnetic block 21 is fixedly connected to the end of the mounting plate 42. Slide rails are provided on both sides of the liquid guiding rod 29. A magnetic element 37 is slidably connected inside the slide rail. The magnetic element 37 has the same magnetic pole as the magnetic block 21. A pressing spring 20 is fixedly connected to the outer wall of the magnetic element 37. The other end of the pressing spring 20 is fixedly connected to the inner wall of the slide rail.

[0034] Lower gears 36 are sleeved on the outer walls of both ends of the liquid guiding rod 29, and a transmission gear 11 is rotatably connected to the outer wall of the mounting part 27. The transmission gear 11 and the lower gear 36 are meshed.

[0035] In this embodiment, before the bamboo composite board is hot-pressed, the equipment performs different surface pretreatment processes for the hot pressure seat 7 for bamboo composite materials of different specifications: if the bamboo composite material to be processed is a regular batch, the mounting box 8 can be driven to reciprocate along the electric linear slide rail 4. This is existing technology and will not be described in detail here. During the reciprocating motion of the mounting box 8, the scraper 23 installed on its surface simultaneously contacts the surface of the hot pressure seat 7 to scrape and clean the wood chips and glue impurities remaining on the surface of the hot pressure seat 7. The cleaned impurities are collected by two dirt storage boxes 24.

[0036] If the bamboo laminated timber to be hot-pressed is thick-gauge bamboo laminated timber, the hot-pressing time for thick-gauge laminated timber is longer, resulting in a significant increase in glue overflow, which easily solidifies and adheres to the surface of the hot pressure seat 7. To avoid excessive glue adhesion affecting the hot-pressing effect, when the mounting box 8 moves from the leftmost to the rightmost position along the electric linear slide rail 4, the scraper 23 still performs the initial cleaning of impurities on the surface of the hot pressure seat 7 according to the above-mentioned conventional process. When the mounting box 8 moves to the rightmost position of the electric linear slide rail 4, the electric drive gear 33 inside the mounting box 8 starts to rotate. Since the upper rack 34 and the lower rack 32 are respectively engaged with the electric drive gear 33, when the electric drive gear 33 rotates, the upper rack 34 can drive the scraper plate 23 to move down into the mounting box 8 as a whole, and the lower rack 32 can drive the base plate 26 to move up as a whole, causing the spraying restriction member 25 to extend out of the mounting box 8 until the scraper plate 28 is in contact with the surface of the thermal pressure seat 7. During the upward movement of the base plate 26, the mounting member 27 mounted on it synchronously drives the transmission gear 11 to move up until the transmission gear 11 and the rack 10 form a meshing engagement.

[0037] When the transmission gear 11 meshes with the rack 10 and the scraper plate 28 is in contact with the surface of the thermal pressure seat 7, the mounting box 8 moves from the rightmost to the leftmost along the electric linear slide rail 4. During this process, the meshing action of the rack 10 and the transmission gear 11 drives the transmission gear 11 to rotate. Since the transmission gear 11 meshes with the lower gear 36 and the tooth diameter of the transmission gear 11 is much larger than that of the lower gear 36, the rotation of the transmission gear 11 can drive the lower gear 36 to rotate at high speed, thereby driving the liquid guiding rod 29 to rotate rapidly. The centrifugal force generated by the high-speed rotation of the liquid guiding rod 29 can drive the magnetic component 37 to overcome the elastic force of the pressing spring 20 and move to the side of the magnetic block 21, reducing the distance between them. When the distance between them is reduced, under the action of the mutually repulsive magnetic force, the magnetic block 21 drives the mounting plate 42 to overcome the elastic force of the return spring 41 and push the blocking plug 39 to disengage from the liquid inlet hole 38.

[0038] After the blocking plug 39 disengages, the release agent in the storage tank 22 enters the liquid guiding rod 29 in large quantities through the liquid inlet 38, quickly filling the liquid guiding rod 29. Under the high-speed rotation of the liquid guiding rod 29, the release agent inside the liquid guiding rod 29 is thrown outward through multiple spraying channels 30. Since the spraying restrictor 25 covers the liquid guiding rod 29, leaving only an opening at the top, only the vertically upward portion of the release agent thrown by each spraying channel 30 can be thrown out through the opening of the spraying restrictor 25 and sprayed onto the surface of the thermostatic seat 7. The release agent thrown in other directions collects inside the spraying restrictor 25 and is drawn back into the storage tank by the micro suction pump mounted on the suction pipe 3. The box 22 is recycled. At the same time, when the liquid guide rod 29 rotates rapidly to spray the release agent, the release agent flowing at high speed in the spray channel 30 will hit the liquid breaking plate 31. The liquid breaking plate 31 breaks the release agent into smaller droplets and sprays them onto the surface of the hot pressure seat 7. After the release agent is sprayed, the scraper plate 28 will move with the installation box 8 to scrape the release agent droplets on the surface of the hot pressure seat 7, so that the release agent is evenly attached to form an anti-stick isolation film, which effectively avoids glue overflow and adhesion during subsequent hot pressing and ensures the hot pressing effect. By first scraping and cleaning impurities and then spraying and scraping the release agent, the adaptability of the equipment to thick bamboo composite materials and the hot pressing quality can be significantly improved.

[0039] Example 2: Please refer to Figure 1 - Figure 12 This embodiment further describes Example 1. The detection mechanism includes a detection box 12 fixedly connected to the outer wall of the mounting box 8. The detection box 12 has a lower chamber 16, a sealing chamber 15 and an upper chamber 14 inside. The lower chamber 16, the sealing chamber 15 and the upper chamber 14 are slidably connected to a plurality of sliding tubes 17. Each of the plurality of sliding tubes 17 has a through hole 19.

[0040] One end of the multiple sliding tubes 17 located inside the upper chamber 14 is sealed, and the other end of the multiple sliding tubes 17 located outside the detection box 12 is fixedly connected to a telescopic rod 18. The other end of the telescopic rod 18 is connected to the outer wall of the detection box 12.

[0041] A push plate 2 is slidably connected to the main body 1 of the equipment, and a side pressure plate 9 is installed on the side wall of the main body 1 of the equipment.

[0042] Both sides of the bracket 5 are fixedly connected to racks 10, and the racks 10 and the transmission gears 11 are meshed.

[0043] In this embodiment, after the surface pretreatment of the hot pressure seat 7 is completed, the mounting box 8 is reset to its initial position. At this time, the bamboo strips of the bamboo composite material raw material after being coated with glue are placed on the main body 1 of the equipment in sequence. The raw material is pushed to the bottom of the hot pressure seat 7 by the push plate 2. Before the raw material enters the hot pressing area, the vision detector 13 performs bamboo node detection on the batch of raw materials. If a small uncleaned bamboo node is detected, the vision detector 13 drives the telescopic rod 18 of the corresponding area to perform a rapid retraction and then reset stroke (this is the prior art and will not be described in detail here). During the retraction and extension reset process of the telescopic rod 18, it will push the through hole 19 on the slide tube 17 to briefly enter the upper chamber 14. At this time, the red dye in the upper chamber 14 will enter the slide tube 17 through the through hole 19 and drip a small amount onto the bamboo node area through the slide tube 17. Markings are used to remind operators to focus on polishing the area after hot pressing to eliminate bamboo joint defects. If a large uncleaned bamboo joint is detected and it is determined to affect the hot pressing effect, the vision detector 13 drives the telescopic rod 18 of the corresponding area to perform a rapid extension and return stroke, pushing the through hole 19 briefly into the lower chamber 16. The blue dye in the lower chamber 16 enters the slide tube 17 through the through hole 19 and drips onto the bamboo joint area marking. At the same time, the equipment stops in conjunction with the marking. The operator can replace the raw material containing large bamboo joints according to the marking. After the vision inspection is qualified, the push plate 2 slowly pushes the raw material to the hot pressing area. The side pressure plate 9 extends to push the loose raw material into a regular state. Then the hydraulic rod 6 extends and heats and pressurizes the raw material through the hot pressure seat 7 to achieve uniform heating and pressing, thereby completing the hot pressing operation.

[0044] It should be noted that the dye used in this technical solution is a water-soluble dye, which does not contain heavy metals or highly corrosive components. Its water-based system will not contaminate the surface of bamboo and will not react with commonly used bamboo adhesives such as phenolic resin and polyurethane glue, thus not affecting the curing effect of the adhesive. At the same time, it will not damage the Teflon coating on the surface of the hot pressure seat 7. The dye will not decompose or fade under the hot pressing temperature of the hot pressure seat 7, but will only adhere to the surface of bamboo. It can be completely removed by sanding, leaving no color residue.

[0045] It should be noted that the hot pressure seat 7 is equipped with a serpentine heating tube inside, through which high-temperature heat transfer oil is circulated (temperature controlled at 120-150°C). The surface of the hot pressure seat is equipped with multiple temperature sensors (5cm apart) to provide real-time temperature data feedback. The flow rate of the heat transfer oil is adjusted through the temperature control system to ensure that the temperature difference on the surface of the hot pressure seat does not exceed two degrees Celsius, thus achieving uniform heating.

[0046] It should be noted that both the lower chamber 16 and the upper chamber 14 are equipped with liquid inlets (not shown in the figure).

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0048] 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.
