Description

Technical Field

[0001] This invention relates to the field of particleboard preparation technology, specifically to a steel strip hot press for particleboard preparation. Background Technology

[0002] Particleboard undergoes a high-temperature, high-pressure hot-pressing process during its manufacturing to achieve bonding, densification, and shaping. However, in actual production, when particleboard is pressed by a hot press, uneven heating or pressure distribution of the surface fibers can easily lead to defects such as surface cracks, bulges, and carbonization. These defects not only affect the mechanical strength and appearance quality of the finished product but may also cause breakage and delamination during subsequent sanding and veneer processes. Furthermore, the wood dust generated during hot pressing adheres to the board surface, exacerbating surface unevenness and uneven heat transfer, further affecting the pressing quality.

[0003] Current technologies generally employ manual or optical inspection devices at the hot press exit to inspect the surface of the formed particleboard using visible light cameras or infrared detectors. Simultaneously, some equipment incorporates airflow dust removal devices or mechanical scraper structures in the post-hot pressing stage to remove surface-adhered particles and improve board flatness. These methods can identify defects such as obvious cracks and dents to a certain extent, and, in conjunction with dust removal mechanisms, improve the appearance quality of the particleboard. This represents a relatively common inspection and surface treatment solution in current industrial production.

[0004] However, the aforementioned conventional technologies suffer from problems such as detection delay, response lag, and fragmented action chains. Existing detection devices are mostly independent vision modules, which cannot provide synchronized feedback with the hot press's movements.

[0005] Therefore, in order to address the existing shortcomings, we conducted research and improvements and proposed a steel strip hot press for particleboard preparation. Summary of the Invention

[0006] The purpose of this invention is to provide a steel strip hot press for particleboard preparation, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a steel strip hot press for particleboard preparation, comprising: an upper press and a worktable, wherein a main frame is connected to the back of the upper press and the worktable, a hydraulic station is provided in the middle of the inner side of the upper press, hydraulic telescopic rods are provided on both sides of the hydraulic station, an upper pressure plate is provided at the bottom of the hydraulic telescopic rods, a placement plate is provided on the top of the worktable near the bottom of the upper pressure plate, and a lower pressure plate is provided at one end of the placement plate; A crack recognition mechanism is provided at the bottom of the center of the front of the upper press. The crack recognition mechanism includes a recognition camera, which is located at the center of the bottom of the front of the upper press.

An auxiliary mechanism is provided on the inner side of the lower pressure plate. The auxiliary mechanism includes a counterweight bar, which is located in the middle of the inner side of the lower pressure plate.

[0008] Furthermore, the crack identification mechanism also includes a rotating shaft, a rectangular groove, a first spring, a push bar, a second spring, a bearing plate, a first sliding shaft, a sliding sleeve, a third spring, a rotating plate, an outer frame, an electrically controlled telescopic rod, a counterweight, a clamping bar, and a material removal plate. The counterweight is disposed on both sides of the back of the lower pressure plate, and an electrically controlled telescopic rod is disposed on the back of the counterweight. The clamping bar is disposed on the outer side of the front end of the placement plate, and an adapter slip ring is disposed at the bottom of the clamping bar. A horizontal shaft is disposed on the inner side of the adapter slip ring, and a first spring is sleeved on the outer side of the horizontal shaft. A rectangular groove is disposed on the outer side of the first spring. A stripping plate is provided on the outer side of the strip, a rotating plate is provided at the middle of the bottom of the stripping plate, a rotating shaft is provided on the inner side of the rotating plate, an outer frame is provided on both sides of the upper front of the worktable, a first sliding shaft is provided on the inner side of the outer frame, a sliding sleeve is provided at the middle of the outer side of the first sliding shaft, a second spring is provided on the front of the first sliding shaft away from the sliding sleeve, a third spring is provided on the front of the first sliding shaft near the sliding sleeve, a push bar is provided on the top of the sliding sleeve, a support plate is provided on both sides of the bottom front of the stripping plate, and a rectangular channel is provided through the inner side of the vertical part on both sides of the clamping strip.

[0009] Furthermore, the recognition camera is equipped with an image recognition component, which includes a control module. The recognition camera is used to acquire surface images of the particleboard in real time during the hot pressing process. The control module has a built-in crack recognition dataset for comparing and analyzing the acquired images. When the crack area on the particleboard surface exceeds a preset standard value, the control module sharpens and enhances the shadows of the crack edge area to improve the crack recognition accuracy and outputs a control signal to the electrically controlled telescopic rod electrically connected to the recognition camera, causing the electrically controlled telescopic rod to perform corresponding linkage actions.

[0010] Furthermore, the control module is an embedded processing unit with a built-in deep learning dataset for identifying cracks on the particleboard surface. The dataset includes standard crack size, morphological features, and edge grayscale threshold parameters. When the control module detects that the crack area on the particleboard surface exceeds a preset standard value, it performs image sharpening processing on the crack area edge and highlights the crack outline by increasing shadow contrast to improve crack identification accuracy. At the same time, the control module outputs control signals to the electrically controlled telescopic rod connected to it. The identification camera is an industrial vision camera with a high-temperature protective cover and dustproof lens, which can continuously acquire clear images under hot and pressure conditions.

[0011] Furthermore, the material removal plate and the rotating plate are fixedly connected, and the material removal plate and the rotating shaft form a rotating structure. When the material removal plate is not rotating, its surface is parallel to the surface of the placement plate.

[0012] Furthermore, the chip removal mechanism also includes a knocking block, a side-shifting strip, a fourth spring, a limiting ring, an attached shifting plate, a second sliding shaft, an inner shifting strip, a pusher plate, an air inlet pipe, a positioning clamping plate, and a telescopic tube. One end of the fan is provided with an air inlet pipe, and one end of the air inlet pipe is provided with a telescopic tube. One end of the telescopic tube is provided with a positioning clamping plate. A foldable spray hole is provided at the end of the telescopic tube near the lower pressure plate.

The bottom of the inner shifting strip is provided with an attached shifting plate. One end of the attached shifting plate is provided with a second sliding shaft. A fourth spring is sleeved on the outside of the second sliding shaft. One end of the fourth spring is provided with a limiting ring. The other end of the second sliding shaft is provided with a protrusion, which is fixedly connected to the bottom of the clamping strip. The side-shifting strip is located on one side of the back of the counterweight, and one side of the side-shifting strip is provided with a knocking block.

[0013] Furthermore, the surface of the striking block and one end of the inner moving strip are on the same center line, and the rectangular channel between the inner moving strip and the clamping strip forms a moving structure.

[0014] Furthermore, the fan is equipped with a motor. When the recognition camera detects in real time that the surface condition of the hot-pressed particleboard meets the preset production standards, the control module built into the recognition camera sends a start signal to the motor of the fan to drive the fan to work.

[0015] Furthermore, the auxiliary mechanism also includes a pusher protrusion, a reset protrusion, a pusher bar, a front notch, an inner bottom groove, a fifth spring, a slider, a shaft groove, and an arc-shaped impact part. An arc-shaped impact part is provided on one side of the front of the counterweight bar, a slider is provided on one side of the bottom of the counterweight bar, a fifth spring is provided on one side of the slider, and an inner bottom groove is provided on the outer side of the slider. The front notch is located on the front of the lower pressure plate, and a shaft groove is provided at the bottom of the inner side of the front notch. A vertical shaft is inserted into the inner side of the shaft groove, and a pusher bar is provided at the top of the vertical shaft. An arc-shaped impact part is provided at the back of the pusher bar near the counterweight bar. The pusher protrusion is located at the top of the inner moving bar on the side near the lower pressure plate, and the reset protrusion is located at the top of the inner moving bar on the side away from the lower pressure plate. The position of the pusher protrusion is forward of the position of the reset protrusion.

[0016] Furthermore, the pusher bar can rotate unidirectionally inside the front notch, and the counterweight bar has inclined surfaces on both sides, which can withstand the pressure from the surfaces of the push-out protrusion and the reset protrusion.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves real-time identification and intelligent judgment of surface cracks in particleboard through the collaborative work of a recognition camera and an embedded control module. The control module analyzes the crack morphology and edge grayscale based on deep learning algorithms, automatically outputting control signals to drive the electrically controlled telescopic rod to complete the linkage action. The system realizes closed-loop control of identification, judgment, and rejection, avoiding errors from manual inspection and improving the pass rate and automation level of the particleboard hot-pressing process; 2. This invention achieves automatic chip removal by controlling a blower with a camera. After the camera identifies that the particleboard meets production standards, the control module sends a start signal to the blower motor. The blower then expands its telescopic tube to blow out high-pressure airflow, precisely cleaning the surface of the placed particleboard. The knocking blocks, sliding shafts, and limit rings in the mechanical chain work together to ensure synchronous resetting of the blower mechanism. The system effectively reduces the accumulation of hot-pressed debris, improving production continuity and equipment stability. 3. This invention achieves automatic ejection of defective particleboard through the coordinated design of the counterweight, pusher, and protrusions in the auxiliary mechanism. The extrusion and resetting protrusions drive the counterweight in both directions at different stages, and the arc-shaped impact and rotation structure pushes the pusher to automatically remove defective boards. This design utilizes mechanical transmission for graded rejection, eliminating the need for additional actuators, ensuring continuous production line operation, and reducing maintenance costs.

[0021] Example: like Figures 1 to 16 As shown, a steel strip hot press for particleboard preparation includes: an upper press 1 and a worktable 10. The back of the upper press 1 and the worktable 10 are connected to a main frame 6. A hydraulic station 3 is provided in the middle of the inner side of the upper press 1.

A placement plate 29 is provided on the top of the worktable 10 near the bottom of the upper pressure plate 30. A lower pressure plate 24 is provided at one end of the placement plate 29. A crack recognition mechanism is provided at the bottom of the center of the front of the upper press 1. The crack recognition mechanism includes a recognition camera 2, which is located at the center of the bottom of the front of the upper press 1. Chip removal mechanisms are provided on both sides of the placement plate 29. The chip removal mechanism includes a fan 9, which is located on both sides of the workbench 10. An auxiliary mechanism is provided on the inner side of the lower pressure plate 24. The auxiliary mechanism includes a counterweight bar 39, which is located in the middle of the inner side of the lower pressure plate 24. In this process, the user places the particleboard on top of the placement plate 29, with one end of the particleboard abutting against the surface of the lower pressure plate 24. After the hydraulic station 3 is started, the hydraulic station 3 drives the hydraulic telescopic rod 4 to descend inside the upper press 1. At the same time, the bottom of the hydraulic telescopic rod 4 drives the upper pressure plate 30 to descend. After the upper pressure plate 30 descends, it performs a heat pressing treatment on the particleboard.

[0022] Example 1: As Figures 1 to 16As shown, the crack identification mechanism also includes a rotating shaft 12, a rectangular groove 13, a first spring 14, a push bar 15, a second spring 16, a bearing plate 17, a first sliding shaft 18, a sliding sleeve 19, a third spring 20, a rotating plate 21, an outer frame 22, an electrically controlled telescopic rod 23, a counterweight 25, a clamping bar 28, and a material removal plate 31. The counterweight 25 is located on both sides of the back of the lower pressure plate 24, and the electrically controlled telescopic rod 23 is located on the back of the counterweight 25. The clamping bar 28 is located on the outer side of the front end of the placement plate 29, and an adapter slip ring is located at the bottom of the clamping bar 28. A horizontal shaft is located on the inner side of the adapter slip ring, and the first spring 14 is sleeved on the outer side of the horizontal shaft. A rectangular groove 13 is located on the outer side of the first spring 14. 3. A material removal plate 31 is provided on the outer side of the clamping bar 28. A rotating plate 21 is provided at the middle of the bottom of the material removal plate 31. A rotating shaft 12 is provided on the inner side of the rotating plate 21. An outer frame 22 is provided on both sides of the upper front of the worktable 10. A first sliding shaft 18 is provided on the inner side of the outer frame 22. A sliding sleeve 19 is provided at the middle of the outer side of the first sliding shaft 18. A second spring 16 is provided on the front of the first sliding shaft 18 away from the sliding sleeve 19. A third spring 20 is provided on the front of the first sliding shaft 18 close to the sliding sleeve 19. A push bar 15 is provided on the top of the sliding sleeve 19. A support plate 17 is provided on both sides of the bottom front of the material removal plate 31. A rectangular channel is provided through the inner side of the vertical part on both sides of the clamping bar 28. The recognition camera 2 is equipped with an image recognition component, which includes a control module. The recognition camera 2 is used to collect surface images of the particleboard in real time during the hot pressing process. The control module has a built-in crack recognition dataset for comparing and analyzing the collected images. When the crack area on the particleboard surface is detected to exceed the preset standard value, the control module sharpens and enhances the shadows of the crack edge area to improve the crack recognition accuracy and outputs a control signal to the electrically controlled telescopic rod 23, which is electrically connected to the recognition camera 2, so that the electrically controlled telescopic rod 23 performs the corresponding linkage action. The control module is an embedded processing unit with a built-in deep learning dataset for identifying cracks on the particleboard surface. The dataset includes standard crack size, morphological features, and edge grayscale threshold parameters. When the control module detects that the crack area on the particleboard surface exceeds the preset standard value, it performs image sharpening processing on the crack area edge and highlights the crack outline by increasing shadow contrast to improve crack recognition accuracy. At the same time, the control module outputs control signals to the electrically controlled telescopic rod 23 connected to it. The recognition camera 2 is an industrial vision camera with a high-temperature protective cover and dustproof lens, which can continuously acquire clear images under hot and pressure conditions. The material removal plate 31 and the rotating plate 21 are fixedly connected, and the material removal plate 31 and the rotating shaft 12 form a rotating structure. When the material removal plate 31 is not rotating, its surface is parallel to the surface of the placement plate 29. The identification camera 2 is fixedly installed at the lower front end of the upper press 1 and is bolted to the main frame 6 via a high-temperature resistant bracket. The camera is equipped with a protective cover and dustproof lens, allowing it to operate continuously in a hot-pressing environment. An embedded control module contains a crack identification dataset for real-time image capture and feature comparison of the particleboard surface after hot pressing. The module performs edge detection and area calculation on the acquired images; when the crack area exceeds a standard value, it outputs an electrical signal to the electrically controlled telescopic rod 23. The electrically controlled telescopic rod 23 is fixed on both sides of the back of the lower pressure plate 24, and drives the counterweight 25 to move back and forth through the connecting seat. When the counterweight 25 moves forward, it pushes the lower pressure plate 24 and the placement plate 29 to produce a slight displacement, so that the clamping bar 28 at the front end of the placement plate 29 moves forward along the rectangular groove 13. The bottom of the clamping bar 28 is connected to the horizontal shaft through the adapter slip ring. The first spring 14 is sleeved on the outside of the sliding sleeve 19. One end of the first spring 14 is fixed to the inner wall of the rectangular groove 13 to provide the reset elastic force. When the clamping bar 28 moves, the material removal plate 31 fixed on its outer side drives the rotating shaft 12 to rotate through the rotating plate 21 at the bottom. The two ends of the rotating shaft 12 are embedded in the outer frame 22. The front end of the material removal plate 31 is provided with a support plate 17. The support plate 17 is pushed up by the push bar 15. The push bar 15 is fixed to the sliding sleeve 19. The sliding sleeve 19 moves on the first sliding shaft 18 and is controlled by the second spring 16 and the third spring 20. The second spring 16 is located on the side away from the sliding sleeve 19 and provides a restoring force. The third spring 20 is located on the side close to the sliding sleeve 19 and plays a buffering role. When the push bar 15 is pushed by force to move the sliding sleeve 19 in the direction of the arrow, the support plate 17 generates an upward pushing force, and the edge of the material removal plate 31 is raised, lifting the unqualified particleboard from the placement plate 29 to achieve automatic rejection. After the operation is completed, once the rejecting plate 31 has finished its lifting and rejection action, the first spring 14 releases its elasticity within the rectangular groove 13, causing the clamping bar 28 and the matching slip ring to return to their original positions along the horizontal axis. The second spring 16 extends at the distal end of the first sliding shaft 18, causing the sliding sleeve 19 to slide back to its initial position. The third spring 20, after being compressed near the sliding sleeve 19, recovers its original position, pushing the pusher bar 15 and the support plate 17 back to their original positions. Through this sequential reset, the clamping bar 28, the sliding sleeve 19, and the rejecting plate 31 return to their initial positions, completing one full inspection and rejection cycle.

[0023] Example 2: Figures 1 to 16As shown, the chip removal mechanism also includes a knocking block 37, a side-shifting strip 36, a fourth spring 35, a limiting ring 34, an attached shifting plate 33, a second sliding shaft 32, an inner shifting strip 27, a pusher plate 11, an air inlet pipe 8, a positioning plate 7, and a telescopic tube 5. One end of the fan 9 is equipped with an air inlet pipe 8, and one end of the air inlet pipe 8 is equipped with a telescopic tube 5. One end of the telescopic tube 5 is equipped with a positioning plate 7. The end of the telescopic tube 5 near the lower pressure plate 24 is equipped with a foldable spray nozzle, and the other end of the telescopic tube 5 is equipped with a pusher plate. The inner sliding strip 27 is provided on one side of the surface of the pusher 11, and the bottom of the inner sliding strip 27 is provided with the attached sliding strip 33. One end of the attached sliding strip 33 is provided with the second sliding shaft 32, and the outside of the second sliding shaft 32 is fitted with the fourth spring 35. One end of the fourth spring 35 is provided with the limit ring 34, and the other end of the second sliding shaft 32 is provided with the protrusion. The protrusion is fixedly connected to the bottom of the clamping strip 28. The side sliding strip 36 is provided on one side of the back of the counterweight 25, and a knocking block 37 is provided on one side of the side sliding strip 36. The surface of the tapping block 37 and one end of the inner moving strip 27 are on the same center line, and the inner moving strip 27 and the rectangular channel of the clamping strip 28 form a moving structure; The blower 9 is equipped with a motor. When the identification camera 2 identifies in real time that the surface condition of the hot-pressed particleboard meets the preset production standard, the control module built into the identification camera 2 sends a start signal to the motor of the blower 9 to drive the blower 9 to work. The fan 9 houses a motor, with its inlet end connected to the inlet pipe 8 and its outlet end connected to the nozzle via a telescopic tube 5. The telescopic tube 5 has a positioning plate 7 on its outer side for securing it to the side wall of the machine during installation. The nozzle has a foldable structure; when closed, it prevents dust backflow, and when open, it sprays high-pressure airflow to remove particleboard debris.

[0024] When the identification camera 2 detects that the particleboard surface meets the production standard, the control module sends a start signal to the fan 9 motor. After the fan 9 starts, it delivers airflow to the telescopic tube 5 through the air inlet pipe 8. The inside of the tube 5 expands rapidly, and the pusher 11 moves forward accordingly. The pusher 11 drives the inner moving strip 27 to move along the rectangular channel on the clamping strip 28. The bottom of the inner moving strip 27 is connected to the attached moving strip 33. The second sliding shaft 32 at the end of the attached moving strip 33 slides in the channel. A fourth spring 35 is provided on the outer side of the second sliding shaft 32. One end of the spring is fixed to the attached sliding plate 33 by a limiting ring 34, and the other end is in contact with the hole wall for reset buffering. The front end of the inner sliding bar 27 is arranged opposite to the side sliding bar 36. The end of the side sliding bar 36 is fixed with a knocking block 37. When the airflow pressure causes the inner sliding bar 27 to move outward, the side sliding bar 36 moves slightly with the counterweight 25. The knocking block 37 strikes the end face of the inner sliding bar 27, causing it to slide back and forth, driving the nozzle to open and close alternately, thereby realizing the rhythmic blowing dust removal.

[0025] After the airflow stops, the fourth spring 35 resets the second sliding shaft 32, and the telescopic tube 5 retracts to its original state, ensuring stable operation of the equipment.

[0026] Example 3: Figures 1 to 16 As shown, the auxiliary mechanism also includes a pusher protrusion 26, a reset protrusion 38, a pusher bar 40, a front notch 41, an inner bottom groove 42, a fifth spring 43, a slider 44, a shaft groove 45, and an arc-shaped impact part 47. An arc-shaped impact part 47 is provided on one side of the front of the counterweight bar 39, a slider 44 is provided on one side of the bottom of the counterweight bar 39, a fifth spring 43 is provided on one side of the slider 44, an inner bottom groove 42 is provided on the outer side of the slider 44, and the front notch 41 is located on the lower pressure plate 24. On the front side, a shaft groove 45 is provided at the bottom of the inner side of the front notch 41. A vertical shaft is inserted into the inner side of the shaft groove 45. A pusher bar 40 is provided at the top of the vertical shaft. An arc-shaped impact part 46 is provided at the back end of the pusher bar 40 near the counterweight bar 39. A pusher protrusion 26 is provided at the top of the inner moving bar 27 on the side near the lower pressure plate 24. A reset protrusion 38 is provided at the top of the inner moving bar 27 on the side away from the lower pressure plate 24. The position of the pusher protrusion 26 is forward of the position of the reset protrusion 38. The push bar 40 can rotate unidirectionally inside the front notch 41. The counterweight bar 39 has inclined surfaces on both sides, which can withstand the pressure from the surfaces of the push-out protrusion 26 and the reset protrusion 38. The counterweight 39 is installed on both sides of the middle part of the lower pressure plate 24, and its bottom is fixedly connected to the slider 44. The slider 44 is slidably placed in the inner bottom groove 42. A fifth spring 43 is installed at the bottom of the groove to provide a reset force. The front end of the counterweight 39 is provided with an arc-shaped impact part 47, which is opposite to the arc-shaped impact part 46 on the back of the pusher bar 40. The pusher bar 40 is inserted into the shaft groove 45 with the vertical axis as the rotation center, and its front end protrudes through the front notch 41. When the inner moving strip 27 moves along the direction of the clamping strip 28, the upper end of the pushing protrusion 26 first contacts the front inclined surface of the counterweight strip 39, generating a squeezing force, causing the slider 44 to slide backward along the inner bottom groove 42, compressing the fifth spring 43. At this time, the counterweight strip 39 moves backward as a whole, and the arc-shaped impact part 47 impacts the arc-shaped impact part 46 of the pusher strip 40, pushing the pusher strip 40 to rotate around the shaft groove 45. The pusher strip 40 extends out from the front notch 41, pushing the unqualified particleboard out of the surface of the placement plate 29. When the push-out protrusion 26 leaves the counterweight bar 39, the distal reset protrusion 38 moves in the opposite direction with the inner moving bar 27 and presses against the inclined surface at the rear end of the counterweight bar 39. The counterweight bar 39 resets forward under the elastic force of the fifth spring 43, and the push bar 40 rotates in the opposite direction in the front notch 41 to return to its initial position. The entire push-out and reset action is completed entirely by mechanical transmission without the need for external drive.
