Description

Technical Field

[0001] The present invention relates to the field of recombinant material manufacturing, in particular to a debonding roller assembly and a debonding device. Background Art

[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 a directional reconstitution process and then combined with resin. Due to their excellent physical and mechanical properties and environmental friendliness, they are widely used in architecture, furniture, landscaping, transportation, and other fields. Sizing is a key step in the production of reconstituted materials, as the uniform distribution of resin within the reconstituted units directly impacts the stability of the final product's performance.

[0003] After gluing, reconstituted unit blanks often contain excess glue adhering to the surface, which drains away automatically under the influence of gravity. To save costs and ensure uniform distribution of the glue within the reconstituted unit, proper debinding is necessary to remove some of the excess glue. Currently, the most commonly used debinding methods in the industry rely on mechanical pressure (such as roller pressing or flat plate pressing) or gravity drainage.

[0004] The gravity leaching process is slow and inefficient, usually taking more than 30 minutes to drain and more than 4 hours to balance the slurry.

[0005] While mechanical pressure (especially direct pressure from a hard roller or flat plate) can effectively expel some of the adhesive, it has significant drawbacks: excessive, concentrated pressure can easily crush the cellular structures (such as vessels and thin-walled cells) within the recombinant unit, leading to localized strength loss, material damage, or even fracture, seriously impacting subsequent processing. Pressure is often transmitted unevenly across the thickness and planar direction of the sheet. Different pressures are applied to the edges, center, and between thickness layers of the sheet, resulting in significant differences in the amount of adhesive expelled. This can cause large gradients in the adhesive distribution within the recombinant unit, with localized areas containing excessively high or low adhesive content, leading to warping and deformation of the finished product, internal stress concentration, large variations in mechanical properties, and inconsistent thickness expansion rates due to water absorption.

[0006] Therefore, the field of recombinant unit production urgently needs a non-destructive debinding device with uniform and controllable force. Summary of the Invention

[0007] The present invention provides a debonding roller assembly and a debonding device, which can efficiently and evenly remove excess glue without damaging the internal structure of the reconstitution unit, ensuring the uniformity of glue distribution in the reconstitution unit blank, thereby significantly improving the comprehensive performance stability, pass rate and added value of the final product.

[0080] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described with reference to the accompanying drawings. Figures 1 to 13 The technical solutions of the present invention are clearly and completely described in detail with reference to the accompanying drawings and specific embodiments.

[0081] On the one hand, the present invention provides a debonding roller assembly, comprising a frame 1, a slide plate 2, an upper roller assembly 3, a lower roller assembly 4 and a lifting drive assembly 5, such as Figures 1 to 10 shown.

[0082] The frame 1 includes a first side plate 11 and a second side plate 12 that are arranged opposite to each other. Two slide plates 2 are provided, which are respectively connected to the first side plate 11 and the second side plate 12 for vertical sliding connection.

[0083] The upper roller assembly 3 is positioned between two opposing slides. It comprises a hollow upper roller shaft 31, with a first air inlet 311 at one or both ends for connection to an external air extraction device. Both ends of the upper roller shaft 31 are fixedly connected to the slide 2. A first notch 312 is defined in the middle of the upper roller shaft 31, communicating with the first air inlet 311. A solid cylindrical upper roller 32 is coaxially mounted on the upper roller shaft 31. The outer wall of the upper roller shaft 31 mates with the inner wall of the upper roller 32, and the upper roller 32 rotates relative to the upper roller shaft 31. The sidewalls of the upper roller 32 are provided with first through-holes 321, arranged in an array around the circumference and axially of the upper roller 32. When the upper roller 32 rotates, the first notches 312 communicate with corresponding first through-holes 321. The upper roller assembly 3 further includes an upper gear end cover 33 fixedly disposed on one end surface of the upper rotating roller 32 , and a roller end cover 34 is fixedly connected to the other end surface of the upper rotating roller 32 .

[0084] The lower roller assembly 4 is disposed between the first side plate 11 and the second side plate 12. It comprises a hollow lower roller shaft 41, with a second air intake 411 at one or both ends for connection to an external air extraction device. The lower roller shaft 41 is fixed to the first and second side plates 11, 12, respectively. A second notch 412 is defined in the middle of the lower roller shaft 41, communicating with the second air intake 411. A solid cylindrical lower roller 42 is coaxially sleeved on the lower roller shaft 41. The outer wall of the lower roller shaft 41 mates with the inner wall of the lower roller 42, and the lower roller 42 rotates relative to the lower roller shaft 41. Second through-holes 421 are defined in the sidewalls of the lower roller 42, arranged in an array around the circumference and axially of the lower roller 42. When the lower roller 42 rotates, the second notches 412 communicate with the corresponding second through-holes 421. The first notch 312 of the upper roller 31 and the second notch 412 of the lower roller 41 are positioned opposite each other, i.e., the first notch 312 of the upper roller 31 faces downward, while the second notch 412 of the lower roller 41 faces upward. The lower roller assembly 4 also includes a lower gear end cap 43 fixed to one end face of the lower rotating roller 42. The upper gear end cap 33 and the lower gear end cap 43 correspond vertically and mesh with each other to transmit power, enabling the upper and lower rotating rollers 32 and 42 to rotate in opposite directions. A sprocket end cap 44 is fixed to the other end face of the lower rotating roller 42, which is used to connect to an external rotation drive mechanism.

[0085] The upper roller 32 has a central, axial through-hole. The upper roller shaft 31 passes through this through-hole, with the outer wall of the upper roller shaft 31 abutting against the inner wall of the upper roller 32. The lower roller 42 has a central, axial through-hole. The lower roller shaft 41 passes through this through-hole, with the outer wall of the lower roller shaft 41 abutting against the inner wall of the lower roller 42. Both the upper roller shaft 31 and the lower roller shaft 41 are hollow, serving as both a channel for transferring the glue and the central axis of rotation for the upper and lower rollers 31 and 42.

[0086] The sidewall of the upper roller 32 is provided with a circumferential and axial array of first through-holes 321, while the lower roller 42 is provided with a plurality of second through-holes 421. The diameters of the first and second through-holes 321, 421 can be tailored to the design requirements of the recombination unit. It is understood that when the diameters of the first and second through-holes 321, 421 are larger, the adsorption force at the locations where the diameters of the first and second through-holes 321, 421 are located is greater; when the diameters of the first and second through-holes 321, 421 are smaller, the adsorption force at the locations where the diameters of the first and second through-holes 321, 421 are located is less.

[0087] The axially arranged first through-holes 321 of the upper rotating roller 32 form a row. Similarly, the axially arranged second through-holes 421 of the lower rotating roller 42 form a row. The distance between adjacent rows of first through-holes 321 and / or second through-holes 421 can be configured based on the design requirements of the reassembly unit. It is understood that when the distance between adjacent rows of first through-holes 321 and / or second through-holes 421 is large, the adhesive force of the debonding roller assembly is weak; when the distance between adjacent rows of first through-holes 321 and / or second through-holes 421 is small, the adhesive force of the debonding roller assembly is strong.

[0088] The upper roller 32, upper gear end cap 33, and roller end cap 34 are fixed together and rotate together relative to the upper roller shaft 31. The lower roller 42, lower gear end cap 43, and sprocket end cap 44 are fixed together and rotate together relative to the lower roller shaft 41. The first notch 312 of the upper roller shaft 31 faces downward, while the second notch 412 of the lower roller shaft 41 faces upward. During roller rotation, the two through-slots remain opposed to each other, facing the recombination unit containing the adhesive liquid. As the upper and lower rollers 32 and 42 rotate, a portion of the first through-hole 321 always aligns with the first notch 312, and the second through-hole 421 always aligns with the second notch 412, ensuring continuity during the debinding process. External vacuum equipment operates through the first and second suction ports 311 and 411, creating an adsorption force on the roller surface to selectively remove a portion of the adhesive liquid within the recombination unit. Compared with the traditional direct pressure debinding method, this solution achieves a contact-type and gentle debinding effect through adsorption force, sucking away and collecting excess glue on the surface of the reorganization unit after gluing, while effectively avoiding material damage and ensuring the uniformity of debinding and quality stability in the reorganization unit.

[0089] The upper gear end cap 33 is fixed to the side of the upper roller 32, and the lower gear end cap 43 is fixed to the side of the lower roller 42, with the two rollers constantly engaged. Regardless of the height of the upper roller 32 (i.e., regardless of the roll gap), this meshed pair of upper gear end caps 33 and lower roller 42 ensures that the upper and lower rollers 32 and 42 rotate in opposite directions at the same linear speed (rotational speed). When the recombined unit material is clamped and conveyed between the upper and lower rollers, inconsistent speeds can cause the material to stretch, wrinkle, or even tear. Forced synchronization completely eliminates this risk. Speed ​​synchronization ensures consistent traction on the material in the roll gap. Simply driving one roller (such as the lower roller 42) drives the other roller (the upper roller 32) synchronously through gear meshing. This eliminates the need for a separate, complex floating drive mechanism (such as a universal coupling or chain / belt tensioning adjustment mechanism) for the upper roller, simplifying drive system design and cost.

[0090] In some specific embodiments, the glue removal roller assembly further includes expansion sleeves 6 at both ends of the upper roller 31 and the lower roller 41. The expansion sleeves 6 are connected to the slide 2 and can lock or unlock the upper roller 31 with the slide 2. The expansion sleeves 6 are connected to the first side plate 11 and the second side plate 12 and can lock or unlock the lower roller 41 with the first side plate 11 and the second side plate 12. The provision of the expansion sleeves 6 ensures that the upper roller 31 does not rotate relative to the slide 2, and the lower roller 41 does not rotate relative to the first side plate 11 and the second side plate 12. This ensures that during roller rotation, the two through grooves remain in a relative position, facing the recombining unit containing the glue liquid.

[0091] The slide plate 2 defines a first placement groove 21 , the first side plate 11 defines a second placement groove 113 , and the expansion sleeve 6 is disposed in the first placement groove 21 and the second placement groove 113 .

[0092] The lifting drive assembly 5 is disposed on the frame 1 and connected to the slide 2 . The lifting drive assembly 5 drives the slide 2 to move up and down, thereby causing the upper rotating roller 32 to move toward or away from the lower rotating roller 42 .

[0093] The debonding roller assembly can debond recombining units of different thicknesses. The lifting drive assembly 5 adjusts the height position of the upper roller assembly 3 so that the upper rotating roller 32 is in contact with the top surface of the recombining unit and the lower rotating roller 42 is in contact with the bottom surface of the recombining unit.

[0094] The linear drive source of the lifting drive assembly 5 includes, but is not limited to, a pneumatic cylinder, an oil cylinder, an electric push rod, and other linear drive elements, which only need to be able to provide a linear drive force. The output end of the linear drive source is connected to the slide to transmit the force.

[0095] In some specific embodiments, the frame 1 further includes an upper horizontal plate 13 , and two ends of the upper horizontal plate 13 are respectively fixed to the top ends of the first side plate 11 and the second side plate 12 .

[0096] An embodiment of the present invention provides a lifting drive assembly 5. The assembly primarily comprises a first drive motor 52, two transmission housings 51, a worm gear, a lead screw 53, and a synchronization shaft. The two transmission housings 51 are symmetrically fixedly mounted above the upper horizontal plate 13. Each transmission housing 51 houses a worm 56. The worm 56 in one transmission housing 51 is directly connected to the output shaft of the first drive motor 52 via a coupling, enabling power input. Within each transmission housing 51, the worm gear and worm 56 mesh with each other and are internally threaded onto the exterior of the lead screw 53. Rotation of the worm gear drives the lead screw 53 in an axial lifting motion, without the lead screw 53 itself rotating. The top end of the lead screw 53 extends through through-holes in the transmission housing 51 and the upper horizontal plate 13, forming a sliding engagement with the through-holes. Its bottom end is fixedly connected to the slide 2, thereby driving the slide 2 to achieve its lifting function. To achieve synchronized rotation of the worm gears 56 on both sides, the assembly also includes a synchronization shaft 54. The ends of the synchronizing shaft 54 ​​are connected to the two worms 56 within the transmission housing 51 via couplings, ensuring synchronized rotation of the worms 56 on both sides. Because the worm gear and worm utilize a self-locking threaded fit, the screw 53 automatically remains fixed in position once it is raised or lowered to a desired position, preventing displacement due to external forces. This structural design not only achieves stable lifting and lowering functionality, but also ensures synchronization of the dual-drive system through the synchronizing shaft. Furthermore, the self-locking properties of the worm gear and worm ensure positional stability when the device is stationary.

[0097] The operation of the first drive motor 52 drives the worm 56 to rotate, which in turn drives the worm wheel to rotate, thereby causing the lead screw 53 to move up and down along the axial direction, thereby driving the lifting and lowering movement of the slide 2. The movement position of the slide 2 is determined based on the operating speed of the first drive motor 52 and the mechanical transmission ratio. The displacement of the slide 2 can be controlled in an open loop: the first drive motor 52 uses a stepper motor or a servo motor (without encoder feedback), and the position is calculated using the following parameters: motor speed (known), running time (timing), mechanical transmission ratio (worm gear reduction ratio + lead screw) and initial position (such as zero point). The displacement of the slide 2 is calculated according to the following formula:

[0098] Displacement = motor speed × time × screw lead / transmission ratio.

[0099] The displacement of slide 2 can also be closed-loop controlled. The system is equipped with an encoder, a grating ruler or a limit switch. The displacement of slide 2 can be directly calibrated by the sensor signal without relying on theoretical calculations.

[0100] Furthermore, the lifting drive assembly 5 also includes a pressure sensor 55, which is fixed to the top of the slide 2 and fixedly connected to the screw rod 53. The pressure sensor 55 and the linear drive source are respectively electrically connected to a controller. The controller is a single chip microcomputer or a PLC controller.

[0101] The debonding roller assembly also includes a slide travel control mechanism 7, which includes a positioning block 71 positioned on the outside of the slide 2. An upper limit switch 72 and a lower limit switch 73 are provided on either the first side plate 11 or the second side plate 12. Each of the upper and lower limit switches 72 and 73 is electrically connected to a controller. When the upper limit switch 72 detects the positioning block 71, the gears of the upper and lower gear end caps 33 and 43 are disengaged (i.e., the maximum thickness of the rebinding unit during debonding). This prevents the transmission gears of the upper and lower gear end caps 33 and 43 from disengaging when the upper roller 32 is raised, thereby preventing the upper roller 32 from losing power. When the lower limit switch 73 detects the positioning block 71, the upper and lower rollers 32 and 42 contact each other. The height of the positioning block 71 at this point can be considered the origin coordinate. At this point, the distance between the upper and lower rollers 32 and 42 is zero, serving as the reference for adjusting the height of the upper roller 32. In the embodiment of the present invention, the upper limit switch 72 and the lower limit switch 73 are disposed on the first side plate 11 , and the upper limit switch 72 and the lower limit switch 73 are fixedly connected to the first side plate 11 via a bracket.

[0102] The upper limit switch 72 and the lower limit switch 73 can be contact-type travel switches, specifically direct-acting switches. The positioning block 71 presses the upper limit switch 72 and the lower limit switch 73 to trigger the control action. The upper limit switch 72 and the lower limit switch 73 can also be non-contact limit switches, including ultrasonic switches and photoelectric switches. The upper limit switch 72 and the lower limit switch 73 are preferably photoelectric switches that can accurately detect the position of the positioning block 71.

[0103] Due to the uneven thickness of the reconstituted sheet material, the debinding roller assembly is first configured with an initial distance in the system. A preset pressure value is then set based on the thickness of the reconstituted sheet material. If the pressure detected by pressure sensor 55 exceeds the preset pressure value, upper roller 32 rises until the pressure detected by pressure sensor 55 returns to the preset value. If pressure sensor 55 detects no pressure or the detected pressure is less than the preset pressure value, upper roller 32 descends until the pressure detected by pressure sensor 55 reaches the preset value. A closed-loop control strategy is employed, with the roller spacing adjusted in real time through pressure feedback. The distance between upper roller 32 and lower roller 42 is dynamically adjusted based on the thickness of the reconstituted sheet material, ensuring uniformity and quality stability during the debinding process within the reconstituted unit.

[0104] If there is no reassembly unit between the upper roller 32 and the lower roller 42, the distance between the upper roller 32 and the lower roller 42 is adjusted by the system to the initial distance (ie, the surfaces of the upper roller 32 and the lower roller 42 are in contact with each other).

[0105] It should be noted that the preset pressure value is a micro pressure to avoid generating a large pressure on the recombination unit.

[0106] The upper gear end cover 33 and the roller end cover 34 rotate relative to the upper roller shaft 31, while the lower gear end cover 43 and the sprocket end cover 44 rotate relative to the lower roller shaft 41. Specifically, a first bearing 36 is provided on each of the upper gear end cover 33 and the roller end cover 34, and the upper roller shaft 31 passes through the two first bearings 36. The lower gear end cover 43 and the sprocket end cover 44 are provided with second bearings 46, and the lower roller shaft 41 passes through the two second bearings 46.

[0107] In some specific embodiments, the first side panel 11 is a “concave” structure, with a slide groove 111 provided along the height, and the slide plate 2 slides in the slide groove 111 ; the second side panel 12 has the same structure as the first side panel 11 .

[0108] In some specific embodiments, upper roller seals 35 are provided on the outer wall of the upper roller shaft 31 between the upper gear end cover 33 and the upper roller 32, and between the roller end cover 34 and the upper roller 32. Lower roller seals 45 are provided on the outer wall of the lower roller shaft 41 between the lower gear end cover 43 and the lower roller 42, and between the sprocket end cover 44 and the lower roller 42. The upper roller seals 35 and the lower roller seals 45 improve the sealing performance of the component connection and provide effective adsorption force for the upper roller 32 and the lower roller 42.

[0109] On the other hand, the present invention provides a debonding device, comprising: a frame 100, at least one debonding roller assembly, a rotary drive mechanism 8 and an air extraction device. The frame 100 is used to install and support the debonding roller assembly and the rotary drive mechanism 8, such as Figures 11 to 13 shown.

[0110] When there are multiple glue removal roller assemblies, they are arranged in parallel on the frame 100.

[0111] The rotary drive mechanism 8 is arranged on the frame 100 and is driven and connected to the sprocket end cover 44; the rotary drive mechanism 8 includes a second drive motor 81 arranged on the frame 100, a first reducer 82 connected to the output shaft of the second drive motor 81 through a belt, a gear 83 and a chain 84 connected to the output shaft of the first reducer 82, and the chain 84 is sleeved on the gear 83 and the sprocket end cover 44.

[0112] The rotary drive mechanism 8 also includes a tensioning pulley (not shown), which is located on one side of the chain 84 and is used to adjust the tension of the chain 84 to ensure that each sprocket end cover 44 and the chain 84 can engage. Otherwise, the sprocket end cover 44 on the lower roller assembly 4 in the middle may slip because it cannot fully engage with the chain 84.

[0113] The air extraction device is disposed on the rack 100 or outside the rack 100 , and is connected to the first air intake port 311 and the second air intake port 411 respectively.

[0114] The aforementioned glue discharge device also includes a liquid receiving assembly 9 for receiving glue liquid that drips due to gravity. Specifically, liquid receiving assembly 9 includes a liquid receiving trough 91, a drain pipe 92, and a waste liquid tank 93. Trough 91 is fixed to the frame 100 and located below the lower roller assembly 4. One end of the drain pipe 92 is fixed to the outlet of the liquid receiving trough 91, and the other end extends out of the liquid receiving trough 91. The waste liquid tank 93, located below the drain pipe 92, stores the glue liquid discharged from the recombination unit.

[0115] Specifically, the upper surface of the liquid receiving tank 91 can have a downward slope along the drainage direction, with the slope ranging from 1% to 5%. To more effectively drain the waste liquid from the liquid receiving tank 91, a propeller 94 is provided in the liquid receiving tank 91 along the drainage direction. One end of the propeller 94 extends out of the liquid receiving tank 91 and is connected to a second speed reducer 96. The input end of the second speed reducer 96 is connected to a third drive motor 95. The other end of the propeller 94 faces the drain pipe 92.

[0116] According to the aforementioned debinding device, it also includes a feed bracket 200 and a discharge bracket 300 for carrying the material to be processed. The feed bracket 200 and the discharge bracket 300 are respectively arranged at opposite ends of the frame 100, and are flush with the position between the upper roller 32 and the lower roller 42. The feed bracket 200 guides the reorganization unit to accurately enter the roller gap, and its bearing surface forms a smooth transition with the roller gap to prevent the material from getting stuck. The discharge bracket 300 receives the plate that has completed debinding, and its horizontal extension length needs to take into account the sagging characteristics of the material. The feed bracket 200 and the discharge bracket 300 together constitute a continuous support surface to prevent the plate from warping and deformation, maintain the flatness of the plate during the debinding process, and ensure the uniformity of debinding.

[0117] When there are multiple debonding roller assemblies, the first through holes 321 of the upper rotating rollers 32 and the second through holes 421 of the lower rotating rollers 42 of adjacent debonding roller assemblies can be staggered in the axial direction to improve the uniformity of debonding of the recombining unit.

[0118] According to the degumming device in this embodiment, since it includes the degumming roller assembly in the first aspect, all the beneficial effects of the degumming roller assembly in the embodiment of the first aspect can be obtained. Specifically, according to the degumming roller assembly in the embodiment of the present application, the external air suction equipment operates through the first air suction port 311 and the second air suction port 411, so that a pressure difference can be formed between the first through hole 321 and the second through hole 421 of the roller and the outside of the roller, forming an adsorption force on the surface of the roller, and selectively removing part of the glue inside the recombination unit. In the process of transporting the electrode using the upper rotating roller 32 and the lower rotating roller 42, the two rollers at the upper and lower ends have adsorption force, thereby discharging excess glue in the recombination unit. Compared with the traditional direct pressurized degumming method, this solution realizes a contact-type and gentle degumming effect through adsorption force, sucking away and collecting the excess glue on the surface of the recombination unit after gluing, while effectively avoiding material damage, ensuring the uniformity of degumming and the stability of quality in the recombination unit.
