Description

Technical Field

[0001] This utility model relates to the field of recombinant unit processing, and in particular to a continuous functional recombinant material production equipment and its sizing device. Background Technology

[0002] Reconstituted materials (such as reconstituted bamboo and reconstituted wood) are high-performance, high-value-added, green, low-carbon, and environmentally friendly composite materials made from bamboo or wood through directional recombination technology and adhesives. Due to their excellent physical and mechanical properties and environmental characteristics, they are widely used in construction, furniture, landscaping, transportation, and other fields. In the production process of reconstituted materials, adhesive application is a crucial step; the uniform distribution of the adhesive within the reconstituted units directly affects the stability of the final product's performance.

[0003] Conventional adhesive spraying methods only allow the adhesive to adhere to the surface of the recombination unit, making it difficult to penetrate the interior and resulting in uneven application. Furthermore, existing adhesive spraying equipment has a low level of automation, requiring manual movement of the recombination unit during the process, which increases the workload for workers and affects the efficiency of adhesive application.

[0059] To make the technical problem to be solved, the technical solution and advantages of this utility model clearer, the following will be described in conjunction with the accompanying drawings. Figures 1 to 5 The technical solution of this utility model is clearly and completely described in conjunction with specific embodiments.

[0060] like Figure 1 and Figure 2 As shown, the glue application device 100 of this utility model embodiment includes a frame 1, a pressure roller assembly 2, a drive mechanism 3, a glue spraying mechanism 4, and a lifting mechanism 5.

[0061] The pressure roller assembly 2 and the drive mechanism 3 are mounted on the frame 1. There is at least one pressure roller assembly 2; when there are multiple pressure roller assemblies 2, all pressure roller assemblies 2 are sequentially distributed on the frame 1 along the conveying direction of the recombination unit. The pressure roller assembly 2 is used by the glue spraying mechanism 4 to roll the recombination unit after spraying glue onto it, thus penetrating the adhesive into the recombination unit. The pressure roller assembly 2 includes two support parts 21 fixed to the frame 1 and arranged opposite to each other. An upper pressure roller 22 and a lower pressure roller 23 are rotatably arranged between the two support parts 21. The upper pressure roller 22 and the lower pressure roller 23 are arranged vertically opposite to each other and form a roller pressing channel. An upper horizontal plate 24 is connected to the top of the two support parts 21 of the pressure roller assembly 2. The upper pressure roller 22 and the lower pressure roller 23 squeeze the recombination unit and further convey it forward in the roller pressing channel.

[0062] The glue spraying mechanism 4 sprays glue onto the recombination unit before the upper pressure roller 22 and lower pressure roller 23 press the recombination unit. After glue spraying, the recombination unit is pressed, allowing the adhesive to penetrate further into the recombination unit.

[0063] The drive mechanism 3 is used to drive the upper pressure roller 22 and / or the lower pressure roller 23 to rotate. The drive mechanism 3 includes a rotary drive assembly 31 and a rotary transmission assembly 32; the rotary drive assembly 31 is mounted on the frame 1 and is used to provide rotary drive force to the rotary transmission assembly 32; the rotary transmission assembly 32 connects the rotary drive assembly 31 and the lower pressure roller 23 of the pressure roller assembly 2.

[0064] Furthermore, the rotary drive assembly 31 is a device capable of outputting rotation, and is a combination of an electric motor, an engine, a hydraulic motor, or one of these with a speed reducer. In this embodiment of the invention, a smaller and technologically mature electric motor is preferred.

[0065] In an optional embodiment, the rotary transmission assembly 32 includes an upper pressure roller shaft 321 and a lower pressure roller shaft 322. The upper pressure roller 22 is coaxially sleeved and fixed on the upper pressure roller shaft 321. The upper pressure roller 22 extends from both ends of the upper pressure roller shaft 321. The lower pressure roller 23 is coaxially sleeved and fixed on the lower pressure roller shaft 322. The lower pressure roller 23 extends from both ends of the lower pressure roller shaft 322 and is rotatably connected to the support part 21. A bearing is provided at the corresponding position of the support part 21, and the end of the lower pressure roller shaft 322 passes through the bearing. The rotary transmission assembly 32 also includes a driving wheel 323 and a driven wheel 324. The driving wheel 323 is disposed on the output shaft of the reducer 142, and the driven wheel 324 is coaxially disposed at the end of the lower pressure roller shaft 322. The driving wheel 323 and one of the driven wheels 324, as well as the driven wheels 324 corresponding to the lower pressure rollers 23 of adjacent pressure roller assemblies 2, are connected by a transmission belt 325 to achieve synchronous transmission. The driving pulley 323 and the driven pulley 324 are sprockets, and the transmission belt 325 is a transmission chain that matches the driving pulley 323 and the driven pulley 324; the driving pulley 323 and the driven pulley 324 are synchronous pulleys, and the transmission belt 325 is a synchronous belt that matches the driving pulley 323 and the driven pulley 324.

[0066] The rotation drive assembly 31 operates, driving the rotation transmission assembly 32, which in turn drives the lower pressure roller 23 to rotate. The upper pressure roller 22 can be a driven pressure roller, meaning that the upper pressure roller 22 is not directly connected to the drive mechanism 3. The reassembly unit is squeezed by the upper pressure roller 22 and the lower pressure roller 23. The rotation of the lower pressure roller 23 drives the upper pressure roller 22 to rotate. Alternatively, the upper pressure roller 22 and the lower pressure roller 23 can also be driven by the drive mechanism 3. Based on the aforementioned rotation transmission assembly 32, the rotation transmission assembly 32 also includes an upper gear disk 326 coaxially fixed on the upper pressure roller shaft 321 and located outside the support part 21, and a lower gear disk 327 coaxially fixed on the lower pressure roller shaft 322 and meshing with the upper gear disk 326. The lower gear disk 327 and the driven wheel 324 are located at opposite ends of the lower pressure roller shaft 322.

[0067] The upper gear disk 326 is fixed on the upper pressure roller shaft 321, and the lower gear disk 327 is fixed on the lower pressure roller shaft 322. The two are always in a meshing state. No matter what height the upper pressure roller 22 is at (i.e., no matter how the roller gap changes), the meshing gear disks forcefully ensure that the upper pressure roller 22 and the lower pressure roller 23 rotate in opposite directions at exactly the same linear velocity (rotation speed).

[0068] Each pressure roller assembly 2 is respectively equipped with two glue spraying mechanisms 4, which are respectively located on the infeed side of the upper pressure roller 22 and the lower pressure roller 23. The structure of the glue spraying mechanism 4 is as follows: Figure 4As shown, the glue spraying mechanism 4 includes an upper adjusting bracket 41 and a lower adjusting bracket 42 mounted on the support 21 of the frame 1 or the pressure roller assembly 2. Both the upper adjusting bracket 41 and the lower adjusting bracket 42 are equipped with glue spraying heads 43, which are connected to a glue supply tank via pipelines. The spray nozzles of the two glue spraying heads 43 face the upper and lower surfaces of the recombination unit, respectively (the glue spraying head 43 on the upper adjusting bracket 41 faces the upper surface of the recombination unit, and the glue spraying head 43 on the lower adjusting bracket 42 faces the lower surface of the recombination unit). The upper adjusting bracket 41 is used to adjust the angle and distance of the upper glue spraying head 43 relative to the recombination unit in the roller pressing channel; the lower adjusting bracket 42 is used to adjust the angle of the lower glue spraying head 43 relative to the recombination unit in the roller pressing channel. After being sprayed with glue by the glue spraying mechanism 4, the recombination unit is further subjected to the squeezing action of the upper pressure roller 22 and the lower pressure roller 23, allowing the adhesive to penetrate deeper into the recombination unit.

[0069] Furthermore, such as Figure 4 As shown, the upper adjusting bracket 41 includes a first crossbar 411, a first shaft connector 412, a mounting rod 413, a second shaft connector 414, and a second crossbar 415. Both ends of the first crossbar 411 are fixed to the upper part of the support 21. The first crossbar 411 is located in front of and above the upper pressure roller 22 (i.e., above the feeding side), and its axial direction is parallel to that of the upper pressure roller 22. One end of the first shaft connector 412 passes laterally through the first crossbar 411 and is fastened to it. The first shaft connector 412 can rotate relative to the first crossbar 411. The mounting rod 413 passes through the other end of the first shaft connector 412 and is fastened to it. The axial direction of the mounting rod 413 is perpendicular to the first crossbar 411. The mounting rod 413 can slide relative to the first shaft connector 412. The bottom end of the mounting rod 413 passes through one end of the second shaft connector 414 and is fastened to the second shaft connector 414. The mounting rod 413 can slide relative to the first shaft connector 412 and the second shaft connector 414. The second crossbar 415 passes through the other end of the second shaft connector 414 and is fastened to the second shaft connector 414. The mounting rod 413 is axially perpendicular to the second crossbar 415. The glue spray head 43 is fixed on the second crossbar 415 and located on one side of the second shaft connector 414. The angle and distance of the glue spray head 43 relative to the recombining unit in the roller pressing channel can be adjusted by the first crossbar 411, the second crossbar 415, the first shaft connector 412, and the second shaft connector 414.

[0070] Furthermore, such as Figure 4As shown, the lower adjusting bracket 42 includes a third crossbar 421, a third shaft connector 422, and a fourth crossbar 423. The two ends of the third crossbar 421 are fixed to the lower part of the support 21. The third crossbar 421 is located below and in front of the upper pressure roller 22 (i.e., below the feeding side), and its axial direction is parallel to that of the lower pressure roller 23. The third crossbar 421 passes through one end of the third shaft connector 422 and is fastened to the second shaft connector 414. The third shaft connector 422 can rotate relative to the third crossbar 421. The fourth crossbar 423 passes through the other end of the third shaft connector 422 and is fastened to it. The axial direction of the fourth crossbar 423 is parallel to that of the third crossbar 421. The glue spray head 43 is fixed to the fourth crossbar 423 and located on one side of the third shaft connector 422. The angle and distance of the lower glue spray head 43 relative to the recombining unit within the roller pressing channel are adjusted by the third crossbar 421, the third shaft connector 422, and the fourth crossbar 423.

[0071] The first shaft connector 412 and the second shaft connector 414 are cross-shaped optical shaft connectors, and the third shaft connector 422 is a parallel double-hole shaft connector with the same diameter and direction; all are commercially available. Taking the use of the first shaft connector 412 as an example: by inserting the first crossbar 411 and the second crossbar 415 into the corresponding holes of the first shaft connector 412, and then screwing in the adjusting screw through the internal threaded hole, the first crossbar 411 and the second crossbar 415 are firmly fixed in the required position by the friction between the screw and the first crossbar 411 and the second crossbar 415, as well as the constraint of the structure of the first shaft connector 412 itself, achieving multi-directional locking.

[0072] Furthermore, two baffles 44 are fixedly mounted on the second crossbar 415 at a distance; the second shaft connector 414 and the spray nozzle 43 are located between the two baffles 44; two baffles 44 are fixedly mounted on the fourth crossbar 423 at a distance; and the third shaft connector 422 and the spray nozzle 43 are located between the two baffles 44. The baffles 44 are designed to prevent the adhesive sprayed from the spray nozzle 43 from being sprayed outside the reassembly unit, thus avoiding pollution of the processing environment.

[0073] A lifting mechanism 5 is located on the upper horizontal plate 24 and driven by the upper pressure roller 22. It drives the upper pressure roller 22 to move up and down relative to the lower pressure roller 23 to adjust the height of the roller pressing channel. This embodiment of the invention provides a specific lifting mechanism that stabilizes the adjusted position of the upper pressure roller 22. The lifting mechanism 5 includes a lifting drive motor 51, a transmission housing 52, a sliding plate 54, and a synchronous shaft 55. The lifting drive motor 51 is located on one end of the upper horizontal plate 24. Two transmission housings 52 are symmetrically fixed above the upper horizontal plate 24. Each transmission housing 52 contains a worm gear. The worm gear in one of the transmission housings is connected to the output shaft of the lifting drive motor via a coupling. A worm wheel meshes with the worm gear inside the transmission housing 52. The worm wheel is threaded onto a lead screw 53. When the worm wheel rotates, it drives the lead screw 53 to move up and down axially, without rotating the lead screw 53. Two sliding plates 54 are provided, slidably connected to the support portions 21 on both sides. The sliding plates 54 are rotatably connected to the upper pressure roller 22. Bearings are installed at corresponding positions on the slide plate 54, and both ends of the upper pressure roller shaft 321 pass through the bearings. The bottom end of the lead screw 53 is fixedly connected to the slide plate 54. The two ends of the synchronous shaft 55 are respectively connected to the worm gears in the two transmission housings 52 through couplings to realize the synchronous rotation of the two worm gears. The threaded engagement between the worm wheel and the worm gear has a self-locking function, so that the lead screw remains in a fixed position after lifting and lowering. The lifting drive motor 51 is a stepper motor or a servo motor (without encoder feedback), and the displacement of the slide plate 54 is controlled by controlling the running time of the lifting drive motor 51. The displacement of the slide plate 54 can also be controlled in a closed loop. The system is equipped with an encoder, a grating ruler or a limit switch, and the displacement of the slide plate 54 can be directly calibrated by sensor signals without relying on theoretical calculations.

[0074] According to the aforementioned adhesive application device, the adhesive application device also includes a collection trough 6 fixed on the frame 1, with the pressure roller assembly 2 and the adhesive spraying mechanism 4 located above the collection trough 6. The collection trough 6 is used to collect the adhesive extruded from the upper pressure roller 22 and the lower pressure roller 23.

[0075] The gluing device of this utility model uses a drive mechanism and a pressure roller assembly to move the recombination unit forward for automatic feeding. The recombination unit is first sprayed with glue by a glue spraying mechanism and then squeezed by a pressure roller. The roller-pressed glue-sprayed surface of the recombination unit allows the adhesive to enter the interior of the recombination unit, ensuring the glue application quality of the recombination unit. At the same time, it greatly reduces the workload of workers and improves the glue spraying efficiency of the recombination unit.

[0076] The glue application device of this utility model adjusts the height of the upper pressure roller through a lifting mechanism to accommodate the recombining units of different thicknesses passing through the roller pressing channel, and can adjust the roller pressing pressure of the recombining units; the glue spraying mechanism is equipped with an adjustment bracket, which adjusts the angle and / or distance of the glue spraying head to the recombining units in the roller pressing channel according to the adjustment of the height of the upper pressure roller by the lifting mechanism, thereby further ensuring the glue application quality.

[0077] This utility model also provides a continuous functional reconstituted material production equipment for the continuous production of reconstituted units by adding functional additives and adhesives. The functional additives include mildew inhibitors, preservatives, flame retardants, etc. A "reconstituted unit" is defined as a board unit that has not undergone functional additive treatment, adhesive application, functional additive treatment, or adhesive application. "Reconstituted material" is defined as a board after functional additive treatment and adhesive application.

[0078] The continuous functional reconstituted material production equipment includes the aforementioned sizing device 100; it also includes a functional additive impregnation device 200, a functional additive content control device 300, a first drying device 400, and a second drying device 500. The discharge end of the functional additive impregnation device 200 is connected to the feed end of the functional additive content control device 300; the discharge end of the functional additive content control device 300 is connected to the feed end of the first drying device 400; the discharge end of the first drying device 400 is connected to the feed end of the sizing device 100; and the discharge end of the sizing device 100 is connected to the feed end of the second drying device 500. The first drying device 400 and the second drying device 500 are equipped with heaters and blower mechanisms, and a drying conveying mechanism is installed inside both devices for continuous conveying of the reconstituted material.

[0079] The functional additive impregnation device 200 is used to add functional additives to the recombination unit. The functional additive impregnation device 200 is a structure combining a roller pressing mechanism and a functional additive solution tank, in which the prepared functional additives are added. The recombination unit passes through the pressure rollers of the functional additive impregnation device 200, and the functional additives are absorbed into the recombination unit under the action of the pressure rollers. The recombination unit with functional additives attached, output from the functional additive impregnation device 200, enters the functional additive content control device 300 to control the content of functional additives in the recombination unit. Specifically, the functional additive content control device 300 can adopt a roller pressing structure, where upper and lower pressure rollers squeeze the recombination unit with functional additives attached, discharging excess functional additives. The content of functional additives in the recombination unit is adjusted by controlling the roller pressing pressure. The recombination unit, coated with functional additives, output from the functional additive content control device 300, enters the first drying device 400 to solidify the functional additives within the recombination unit. The recombination unit output from the first drying device 400 then enters the adhesive application device 100 for adhesive application. The recombination unit, coated with adhesive, output from the adhesive application device 100, enters the second drying device 500 for further adhesive solidification.

[0080] In the preparation of recombinant materials, functional additives are first added to the recombinant units. After the recombinant units adsorb the functional additives, the recombinant units are then sizing. The functional additives are completely coated between the adhesive and the filaments of the recombinant units, thus achieving an organic combination of the functional additives with the recombinant units and the adhesive. This solves the problems of easy migration and loss of additives or adverse effects on the bonding interface in traditional processes, thereby achieving functional durability, performance stability and environmental friendliness.

[0081] The continuous functional recombinant material production equipment of this utility model embodiment includes all the technical solutions described above for the sizing device 100, and thus possesses the beneficial effects of the sizing device 100, which will not be repeated here.
