Description

Technical Field

[0001] This invention relates to the technical field of plate crack detection devices, specifically a novel surface crack detection device for the production of building energy-saving panels. Background Technology

[0002] As a new type of green building material, energy-saving building panels are widely used in modern buildings due to their excellent thermal insulation, sound insulation, lightweight, and high strength properties. Common energy-saving panels include polystyrene (EPS) boards, rock wool boards, and polyurethane composite boards. These materials play an important role in reducing building energy consumption and improving sustainability. However, during production, transportation, installation, and long-term use, energy-saving panels are prone to surface or internal cracks due to mechanical stress, temperature changes, humidity erosion, or material aging. These defects not only affect aesthetics but may also reduce their thermal insulation performance and structural strength, and even lead to safety hazards. Existing traditional crack detection devices mainly rely on manual visual inspection, ultrasound, or computer vision. However, these crack detection devices still have some problems, as follows:

[0003] Existing crack detection devices rely on computer vision or ultrasound. These devices are highly dependent on the intelligence of the equipment system and the accuracy of the detection tip. Such devices are affected by these factors during use. Moreover, these detection components are usually very expensive and precise, and their accuracy can be greatly reduced or even rendered unusable due to high temperatures or accidental impacts, significantly increasing the overall cost of the detection device. Furthermore, existing detection devices rely on computer image reconstruction, which cannot directly display the cracks on the board. Consequently, the crack situation on the board cannot be clearly identified after inspection, affecting subsequent production and processing. Therefore, we propose a new surface crack detection device for the production of building energy-saving panels. Summary of the Invention

[0010] In a preferred embodiment, the outer surface of the drive roller is uniformly arranged with protruding teeth, and the protruding teeth on the side of the rotation direction are arc-shaped. The upper surface of the pressure plate is provided with a protruding strip in the middle directly below the drive roller. The protruding strip and the protruding teeth are correspondingly pressed and moved. The diameter of the transmission gear is larger than the diameter of the first transmission wheel. The diameter of the first transmission wheel is equal to the diameter of the second transmission wheel. The diameter of the second transmission wheel is smaller than the outer diameter of the drive roller.

[0011] In a preferred embodiment, a detection marker assembly is movably installed inside the perforation, the branch pipe is connected in a sealed manner to the external pigment storage device, the height of the external pigment storage device is lower than the height of the branch pipe and lower than the height of the top of the internal structure of the detection marker assembly, the supply pipe is connected in a continuous manner to the branch pipe, and a self-sealing baffle is provided at the bottom end of the supply pipe.

[0012] In a preferred embodiment, the bottom end of the detection needle is rounded, the marking needles are arranged in pairs on the side of each detection needle, the lower part of the marking needle is hollow and a sponge is provided at the bottom end, the upper part passes through the top end of the plate and is located at the bottom end of the pressure plate, the height of the top ends of the detection needle and the two marking needles decreases in a stepped manner, the top plate is attached to the lower surface of the pressure plate, the slot is opened at a position corresponding to the position of the marking needle and the rubber film is located at the bottom end inside the slot.

[0013] In a preferred embodiment, the insert plate structure is provided with a material guiding hose, one end of which is fixedly installed with a collection chamber. A vertical plate is fixedly installed above the inside of the collection chamber. The insert plate structure is L-shaped, with its bottom end located on the marking needle and movably inserted into the groove. The support frame is located at the turning point of the insert plate structure. The two sides of the collection chamber are fixedly connected to the surface of the marking needle through an extension crossbar.

The outer insert plate is slidably disposed against the surface of the partition at one of its turning ends. The top of the return trough near the partition is inclined downward. The bottom end of the partition has a notch. The return plate is vertically disposed inside the return trough and has a rotating pin at its top.

[0016] The present invention has the following beneficial effects:

[0017] 1. This novel surface crack detection device for building energy-saving panels eliminates positional shifts caused by vibration during material feeding by installing a positioning plate at the feeding end. This ensures that the panels are centered below the detection section for comprehensive crack detection, guaranteeing accuracy. An external pigment storage device continuously supplies pigment to the detection marking component. When the marking component moves down and contacts the crack, its bottom marks the surface with pigment. Different color combinations are used for cracks of varying depths. This allows for a clear visual representation of the crack location and depth after detection, facilitating efficient production processing of the panels.

[0018] 2. This novel surface crack detection device for building energy-saving panels utilizes movable detection needles and marking needles installed inside the panel. The rotation of the conveyor belt drives the transmission belt, which in turn drives the transmission gear. This transmission belt's rotational force is transmitted to the drive roller, creating a rotational driving force. The rotation of the drive roller causes the pressure plate to move up and down periodically, causing the detection marking component to periodically press down. When the bottom end of the detection marking component encounters a crack on the panel surface, it inserts into it. The marking needle, under the pressure of the rubber film, contacts the panel surface, and the pigment in the marking head at the bottom of the marking needle marks the panel surface. Cracks of different depths require different numbers and colors of marking needles, thus creating a distinguishing mark on the panel surface. This makes the surface cracks visible and improves the detection effect. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The surface crack detection device for the production of novel building energy-saving panels involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-4A novel surface crack detection device for the production of building energy-saving panels includes a side plate 1. Rotary rollers 2 are movably installed on both sides of the side plate 1. A conveyor belt 3 is movably sleeved on the two rollers 2. A drive motor is connected to one end of one roller 2. A transmission belt 4 is installed on the conveyor belt 3. A positioning plate 5 is fixedly installed at one end of the side plate 1. A vertical rod 6 is fixedly installed at the top center of the side plate 1. A transmission gear 7 is rotatably installed on one side of the vertical rod 6. A first transmission wheel 8 is fixedly installed on one side of the transmission gear 7. A transmission belt 9 is sleeved on the first transmission wheel 8. A second transmission wheel 10 is sleeved on the transmission belt 9. A drive roller 11 is fixedly installed on the side of the second transmission wheel 10. A support assembly 12 is provided at the top center of the side plate 1 via an extension rod. A pressure plate 13 is movably installed at the top of the support assembly 12. An external pigment storage device 14 is provided on one side of the support assembly 12. A detection marking assembly 15 is provided inside the support assembly 12.

[0034] Compared with existing technologies, this application, by setting a positioning plate 5 at the feeding end, eliminates the positional displacement of the board caused by vibration during the feeding process, ensuring that the subsequent board is centered below the detection section for comprehensive crack detection, thus guaranteeing the accuracy of the detection. Simultaneously, an external pigment storage device 14 is provided to continuously supply pigment to the detection marking component 15. When the detection marking component 15 moves down and contacts the crack in the board, its bottom end marks the surface of the board with pigment, and different color combinations are used for cracks of different depths. This allows the location and depth of the crack to be clearly seen based on the surface markings after the board is inspected. Visualizing the crack facilitates efficient production processing of the board. Furthermore, a movable detection needle is provided inside the board body 121. The marking needles 151 and 152 are driven by the rotation of the conveyor belt 3, which in turn drives the transmission belt 4 to rotate, which in turn drives the transmission gear 7 to rotate. This allows the rotational force of the transmission belt 4 to be transmitted to the drive roller 11, forming the rotational driving force of the drive roller 11. The rotation of the drive roller 11 causes the pressure plate 13 to move up and down periodically, which in turn causes the detection marking component 15 to perform periodic downward pressing action. When the bottom end of the detection marking component 15 encounters a crack on the surface of the board, it will insert into it, so that the marking needles 152 will contact the surface of the board under the pressure of the rubber film 157. In this way, the pigment in the marking head set at the bottom end of the marking needles 152 will mark the surface of the board. Cracks of different depths will drop different numbers and colors of marking needles 152, thus forming a mark distinction on the surface of the board, thereby making the surface cracks of the board visible and improving the detection effect of board cracks.

[0035] Please see Figure 1-3A novel surface crack detection device for the production of building energy-saving panels includes a transmission belt 4, which is located on both sides of the conveyor belt 3. The transmission belt 4 is attached to both sides of the conveyor belt 3 by Velcro. The surface of the transmission belt 4 is rough. The teeth on the transmission gear 7 are pointed and are connected to the surface of the transmission belt 4 by meshing.

[0036] In this embodiment, it should be noted that the rotation of the conveyor belt 3 can drive the transmission belt 4 to rotate. The transmission belt 4 can then drive the second transmission wheel 10 and the drive roller 11 to rotate through the transmission gear 7. This allows the conveyor belt 3 to rotate while transporting the sheet material, and simultaneously drive the drive roller 11 above to rotate. This causes the pressure plate 13 to synchronously and continuously drive the detection marking component 15 to move downward, detect cracks on the surface of the sheet material and mark them, thus ensuring the linkage of the entire detection device structure.

[0037] Please see Figure 1-4 A novel surface crack detection device for the production of building energy-saving panels includes two positioning plates 5, which are symmetrically arranged at the feeding end of the energy-saving panel conveyor. The opposite sides of the two positioning plates 5 are arranged with a gradually shrinking structure.

[0038] In this embodiment, it should be noted that by using the gradually shrinking structure of the two positioning plates 5, the energy-saving plate can be gradually transported towards the center during the transportation process, avoiding the displacement of the plate position caused by vibration during transportation, and ensuring the accuracy and reliability of the subsequent detection results of cracks on the plate surface.

[0039] Please see Figure 1-4 A novel surface crack detection device for the production of building energy-saving panels includes a drive roller 11. The outer surface of the drive roller 11 is uniformly arranged with protruding teeth, and the protruding teeth are in an arc structure on the side where the rotation direction is located. The upper surface of the pressure plate 13 is provided with a protruding strip in the middle, directly below the drive roller 11. The protruding strip and the protruding teeth are correspondingly pressed and moved. The diameter of the transmission gear 7 is larger than the diameter of the first transmission wheel 8. The diameter of the first transmission wheel 8 is equal to the diameter of the second transmission wheel 10. The diameter of the second transmission wheel 10 is smaller than the outer diameter of the drive roller 11.

[0040] In this embodiment, it should be noted that by utilizing the diameter difference between the various components, the drive roller 11 can rotate at a linear speed greater than that of the transmission belt 4. This allows the detection mark component 15 to move down more frequently during the movement of the sheet material to detect cracks, thereby ensuring the comprehensiveness of crack detection on the sheet material surface.

[0041] Please see Figure 1-10A novel surface crack detection device for the production of building energy-saving panels includes a support component 12, which includes a plate 121. The plate 121 has several through holes 122 evenly distributed through its upper and lower surfaces. A branch pipe 123 is fixedly installed inside the plate 121. A supply pipe 124 is fixedly installed at the bottom end of the branch pipe 123. A support frame 125 is fixedly installed inside the plate 121.

[0042] In this embodiment, it should be noted that a detection marking component 15 is movably installed inside the perforation 122. The branch pipe 123 is connected to the external pigment storage device 14 in a sealed manner. The height of the external pigment storage device 14 is lower than the height of the branch pipe 123 and lower than the height of the internal structure of the detection marking component 15 when it is moved to the top. The supply pipe 124 is connected to the branch pipe 123 in a sealed manner. The bottom end of the supply pipe 124 is provided with a self-sealing baffle. In this way, the branch pipe 123 can store a portion of pigment, and then replenish the pigment in it during the up-and-down movement of the detection marking component 15 to ensure sufficient pigment during subsequent use, thereby ensuring the reliability of the visualization of cracks on the surface of the board.

[0043] Please see Figure 4-12 A novel surface crack detection device for the production of building energy-saving panels includes a detection marking assembly 15, which comprises a detection needle 151 and a marking needle 152. A first spring 153 is sleeved on the detection needle 151, and a second spring 154 is sleeved on the marking needle 152. A top plate 155 is fixedly installed at the top of the detection needle 151. A through groove 156 is opened on the top plate 155, and a rubber film 157 is fixedly installed inside the through groove 156. An inlet groove is opened on one side of the marking needle 152, and a partition plate 158 is fixedly installed at the opening of the groove. An insert plate structure 159 is embedded in the marking needle 152 at the inlet groove. A material guiding hose 1510 is provided on the insert plate structure 159. A material collection chamber 1511 is fixedly installed at one end of the material guiding hose 1510, and a vertical plate 1512 is fixedly installed above the inside of the material collection chamber 1511.

[0044] In this embodiment, it should be noted that the bottom end of the detection needle 151 has a rounded corner structure, and the marking needles 152 are arranged in pairs on the side of each detection needle 151. The lower part of the marking needle 152 is hollow and has a sponge at the bottom. The top of the upper part passes through the plate 121 and is located at the bottom of the pressure plate 13. The height of the tops of the detection needles 151 and the two marking needles 152 decreases in a stepped manner. The top plate 155 is attached to the lower surface of the pressure plate 13. The slot 156 is opened at a position corresponding to the position of the marking needle 152, and the rubber film 157 is located at the bottom of the slot 156. The insert plate structure 159 has an L-shaped structure, and its bottom end is located on the marking needle 152 and is movably inserted into the slot. The support frame 125 is located at the turning point of the insert plate structure 159 for support. The two sides of the collection chamber 1511 are connected by extension The horizontal bar is fixedly connected to the surface of the marking needle 152. The size of the vertical plate 1512 is smaller than the size of the internal cavity of the collection chamber 1511 and can push open the sealing plate set at the bottom of the supply pipe 124. In this way, the pressure plate 13 can be pressed down to drive the top plate 155 to move down, thereby causing the detection needle 151 to move down and fit against the surface of the plate. When a crack is encountered, the bottom end of the detection needle 151 will be inserted into the crack, thereby causing the top plate 155 to continue to move down, driving the two marking needles 152 to move down one by one. The downward movement is adaptive according to the depth of the crack. After the bottom end of the corresponding marking needle 152 moves down and fits against the surface of the plate, it can mark next to the crack, thereby making the crack visible. During the up and down movement of the marking needle 152, the pigment inside the marking needle 152 can be automatically replenished to ensure the continuous use of the device.

[0045] Please see Figure 10-11 A novel surface crack detection device for the production of building energy-saving panels includes an insert plate structure 159, the insert plate structure 159 includes an outer insert plate 1591, the outer insert plate 1591 has an inner cavity 1592 inside, the top of the outer insert plate 1591 has a return material groove 1593, and a return material plate 1594 is movably installed inside the return material groove 1593.

[0046] In this embodiment, it should be noted that the outer insert plate 1591 has an L-shaped structure, and its bottom end is movably inserted into the marking needle 152. The inner cavity 1592 penetrates both ends of the top horizontal portion of the outer insert plate 1591. The turning end of the outer insert plate 1591 is slidably disposed against the surface of the partition plate 158. The top of the return groove 1593 near the partition plate 158 is inclined downward. The bottom end of the partition plate 158 has a notch. The return plate 1594 is vertically disposed inside the return groove 1593, and a rotating pin is provided at its top. In this way, by moving the marking needle 152 up and down, the outer insert plate 1591... The pigment flows into the inner cavity 1592 when it moves relative to the partition 158 and reaches the gap in the partition 158. During the downward movement of the marking needle 152, the outer insert plate 1591 moves upward relative to the partition 158, scraping away any pigment that leaks during the movement into the return trough 1593. The pigment then automatically flows back into the inner cavity 1592 through a slight rotation at the bottom of the return plate 1594. When the pigment inside the inner cavity 1592 flows into the marking needle 152, the return plate 1594 reverses and restricts the flow, preventing pigment leakage.

[0047] Working principle: The board material is placed on the surface of the conveyor belt 3. The drive motor drives the rotating roller 2 to rotate, which in turn drives the conveyor belt 3 to transport the board material. During the rotation of the transmission belt 4, the transmission gear 7 rotates. The transmission gear 7, through the rotation of the first transmission wheel 8 and the transmission belt 9, drives the second transmission wheel 10 and the drive roller 11 to rotate. The rotation of the drive roller 11 causes the pressure plate 13 to move up and down continuously, thereby compressing the top plate 155 below. This causes the detection needle 151 to move down and fit against the surface of the board material. When there is a crack on the surface of the board material, the detection needle... The bottom end of 151 will be inserted into the crack, and the continuous downward movement of the top plate 155 will compress the marking needle 152 to move down and fit against the surface of the board, thus leaving a mark on the surface of the board. The mark is different depending on the depth of the crack. The downward movement of the marking needle 152 will cause the outer insert plate 1591 to move upward relative to the partition plate 158, scraping the pigment remaining on the surface of the partition plate 158 into the return trough 1593 and back into the inner cavity 1592. The reverse movement will enable the inner cavity 1592 to move to the bottom notch of the partition plate 158 to connect and replenish the pigment, thus ensuring the continuous operation of the device.

[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.
