Description

Technical Field

[0001] This invention relates to the field of tongue and groove production technology for insulation board end faces, specifically a gas-liquid linkage insulation board end face tongue and groove production equipment. Background Technology

[0002] Rock wool insulation boards, with their excellent thermal insulation, fire resistance, sound absorption, and corrosion resistance, are widely used in construction, industry, and transportation. The tongue-and-groove design of insulation boards not only improves product performance but also simplifies the installation process, meeting the market's demand for efficient, safe, and environmentally friendly building materials. With continuous technological advancements and growing market demand, rock wool board tongue-and-groove production equipment is showing great development potential.

[0003] Traditional tongue-and-groove insulation board production processes require cutting one side of the insulation board to leave room for bending. After bending, the baffle is then manually installed. This method not only requires a lot of manpower but is also inefficient. Currently available tongue-and-groove production equipment cannot automatically detect the bending quality after bending, requiring manual inspection and adjustment, which makes it impossible to accurately control the bending quality. Summary of the Invention

[0004] The purpose of this invention is to provide a gas-liquid linkage type insulation board end face tongue and groove production equipment to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gas-hydraulic linkage type insulation board end face tongue and groove production equipment, comprising a base, baffles, and a bending section. An inner frame is provided on the base, and several conveying rollers are installed on the inner frame. A fixed cylinder is installed on the inner frame, and a fixed pressure rod is installed on the output shaft of the fixed cylinder. A bending detection device is installed on the base, and a main slide rod is installed on the base. A crossbeam is installed at the top of the main slide rod, and a hydraulic device is installed on the crossbeam. The output shaft of the hydraulic device passes through the crossbeam and is equipped with a pressing device. The pressing device is slidably connected to the main slide rod. A bending assembly is installed on the base, and the pressing device and the bending assembly cooperate to bend the bending section. Several neatly arranged baffles are provided inside the pressing device.

[0006] The machine is equipped with a control system, which controls the entire tongue and groove production equipment. The insulation board consists of a metal base plate, a metal top plate, and a filling layer. After the insulation board is cut, a fixed-width bending section is formed at the metal base plate. After bending, the bending section changes from horizontal to vertical. The vertical bending section is used to fix the baffle, so that the baffle fits tightly against one side of the insulation board. After bending, the width of the bending section decreases, fixing the lower part of the baffle. The width of the baffle is similar to the height of the filling layer.

[0007] The control system first activates the hydraulic device, and the output shaft of the hydraulic device drives the lowering device to descend initially. The lowering plate descends to the preset height. At this time, the gap between the lowering plate and the pad is less than the thickness of the insulation board. The control system activates the transmission roller to transport the cut insulation board to the lowering plate. Since the thickness of the insulation board is greater than the gap between the lowering plate and the pad, the insulation board cannot pass through the gap. At this time, the insulation side is in contact with the lowering plate. The control system activates the fixing cylinder, and the fixing cylinder drives the fixing rod to descend through the output shaft. The fixing rod presses the insulation board tightly and fixes it. The control system restarts the hydraulic device, and the hydraulic device drives the lowering device to descend further until the lowering plate presses the bent section tightly.

[0008] The pressing device includes a pressing housing, which is slidably connected to the main slide rod and connected to the output shaft of the hydraulic device. A bending and feeding device is slidably installed inside the pressing housing. A feeding housing is installed on the pressing housing, and several feeding rods are installed inside the feeding housing. An electric telescopic rod is installed on the pressing housing, and a pusher plate is installed on the output shaft of the electric telescopic rod. Several baffles are filled between the pusher plate and the feeding housing. A transmission rod is slidably installed on the pressing housing, and a return spring is installed between the transmission rod and the pressing housing. A transmission gear is rotatably installed inside the pressing housing, and the transmission gear is threadedly connected to the transmission rod. The transmission gear meshes with the bending and feeding device. A pressing plate is installed on one side of the pressing housing. A limit block is slidably installed inside the pressing housing, and a limit spring is installed between the limit block and the pressing housing. A feeding slide is provided inside the feeding housing, and a feeding slot is provided inside the pressing plate.

[0009] The limit block is used to block the baffle plate to be unloaded, preventing the baffle plate from tipping over and causing unloading failure and blockage of the unloading slide.

[0010] After the lower pressure plate descends to a certain height, the transmission rod contacts the pad. As the lower pressure plate descends further, the end of the transmission rod is pressed and slides upward relative to the lower pressure shell. When the transmission rod slides, it drives the transmission gear to slide. Since the transmission gear is rotatably connected to the lower pressure shell, it cannot slide. Therefore, through the threaded engagement between the transmission gear and the transmission rod, the transmission gear converts the sliding into rotation. The transmission gear drives the bending and feeding device to slide through the rack. The bending and feeding device drives the attracted baffle to slide in the feeding chute. When it slides to a certain position, the end of the feeding rod begins to enter the feeding slide hole on the feeding plate. When the baffle is completely above the feeding gap, the feeding rod just passes through the feeding slide hole and the annular magnet and contacts one side of the baffle. As the bending and feeding device slides further, the baffle is blocked by the feeding rod and stays in place and detaches from the annular magnet. After the baffle loses the attraction of the annular magnet, it falls into the feeding gap under the influence of its own gravity. Finally, the baffle lands on the bending section.

[0011] The bending and unloading device includes an unloading plate with racks symmetrically mounted on it. The racks mesh with a transmission gear for transmission. An annular magnet is mounted on the unloading plate, as are anti-tipping components. The unloading plate also has unloading sliding holes. In the initial state, the annular magnet is in contact with the baffle and attracts the baffle.

[0012] The anti-tipping assembly includes an anti-tipping housing mounted on a feed plate, an anti-tipping sliding plate installed inside the anti-tipping housing, and an anti-tipping spring installed between the anti-tipping sliding plate and the anti-tipping housing. The spring force of the anti-tipping spring is greater than that of the limit spring.

[0013] During the upward reset process of the pressing device, the transmission rod gradually loses pressure and slides back to its original position under the action of the reset spring. The transmission rod drives the transmission gear to rotate in the opposite direction, thereby causing the bending and feeding device to slide in the opposite direction. After the bending and feeding device slides to a certain distance, the inclined surface of the anti-tipping slide plate on the anti-tipping assembly is in contact with the inclined surface of the limit block. The anti-tipping slide plate further pushes the limit block, and the limit block slides upward against the elastic force of the limit spring under pressure. When the limit block slides completely open, the anti-tipping slide plate presses against the slide plate above the baffle to be fed. Then, the bending and feeding device slides back to its original position, and the anti-tipping slide plate slides inside the anti-tipping housing against the elastic force of the anti-tipping spring. After that, the annular magnet slides and comes into contact with the baffle to be fed. When the material is fed again, the bending feeding device drives the material to be fed away. Since the anti-tilt slide plate is still in the retracted state, under the action of the anti-tilt spring, the anti-tilt slide plate will still hold the baffle above the original material to be fed baffle to prevent it from falling. When the material to be fed baffle slides away from the position of the limit block, the anti-tilt slide plate will also gradually return to its original position and slide away with the bending feeding device. The baffle above the original material to be fed baffle will lose its restraint and fall into the feeding slide. At this time, the limit block will return to its original position under the action of the limit spring and block the baffle that has just fallen into the feeding slide to prevent it from tipping over. Then the output shaft of the electric telescopic rod will drive the push plate to move slightly, so that the neatly arranged upper baffles will be pressed tightly.

[0014] The bending detection device includes a second cylinder and a detection motor. The second cylinder is mounted on a base. The first cylinder is mounted on the output shaft of the second cylinder. A connecting block is mounted on the output shaft of the first cylinder. A limit slide rod is installed between the connecting blocks. A lead screw is rotatably mounted between the connecting blocks. The output shaft of the detection motor passes through the connecting block and is connected to one end of the lead screw. A detector is slidably mounted on the limit slide rod. The detector is threadedly connected to the lead screw.

[0015] The detector includes a detection frame, which is slidably connected to a limiting slide bar and threadedly connected to a lead screw. A crossbar is installed on the detection frame, a detection connecting block is installed on the crossbar, a coil frame is installed on the detection connecting block, an induction coil is installed on the coil frame, and a detection rotating rod is rotatably installed on the crossbar.

[0016] During production debugging or product sampling inspection, after bending is completed, the control system activates the bending detection device. The device uses a first and second cylinder to adjust the position of the detector, ensuring that the two detection pulleys on the detector are in contact with the baffle and the bending section, respectively. During contact, due to the distance difference between the sides of the baffle and the bending section, in the case of a qualified tongue and groove joint, the lower detection pulley will first contact the bending section. As the detector extends further, the lower detection pulley, through the pulley joint, drives the lower detection rod to overcome the spring force of the detection spring and retract towards the detection frame. The lower detection rod drives the detection rotating rod to rotate on the crossbar, which in turn drives the upper detection rod to extend. The upper detection rod then drives the upper detection pulley to extend until the upper detection pulley contacts the portion of the baffle not obscured by the bending section. The two detection pulleys then... When the sliding rod moves, it moves the iron core into or away from the corresponding induction coil. As the iron core moves within the induction coil, it generates an induced electromotive force. At the same speed, the longer the iron core extends into the coil, the greater the induced electromotive force. The control system analyzes the changes in the electromotive force of the upper and lower induction coils to determine the distance difference between the baffle and the bending section. When the distance difference is within the error range, the bending quality is acceptable. When the distance difference is too large and positive, it indicates that the bending angle is too small, and the baffle and bending section may become loose, potentially leading to problems such as falling off. Conversely, when the distance difference is too large and negative, it indicates that the bending angle is too large, which may cause the side of the insulation board and the baffle to dent and deform. The control system controls the extension of the bending cylinder to correct the bending angle, thereby achieving automatic adjustment of the bending degree.

[0017] The detector also includes a detection slide bar, which is slidably mounted on the detection frame. The detection slide bar is movably connected to the detection rotating rod. An iron core is installed at one end of the detection slide bar, and a pulley joint is installed at the other end. A detection pulley is rotatably mounted on the pulley joint, and a detection spring is provided between the pulley joint and the detection frame.

[0018] The bending assembly includes a bracket mounted on a base. A pad is mounted on the bracket, and several multi-stage telescopic curved rods are mounted on the pad. A bending die is mounted at one end of each multi-stage telescopic curved rod, and a bending head is provided on the bending die. A bending cylinder is rotatably mounted on the bracket, and the output shaft of the bending cylinder is rotatably connected to the bending die. The multi-stage telescopic curved rods can gradually extend and retract as the bending die rotates.

[0019] The control system activates the bending cylinder, and the output shaft of the bending cylinder drives the bending die to rotate. Under the action of the multi-stage telescopic crank, the bending die rotates around the pad. The bending head on the bending die performs an initial bend on the bending section while rotating. The angle between the bending section and the side of the insulation board starts to decrease from 90°. After bending to the preset angle, the control system drives the pressing device to rise through the hydraulic device. When the pressing device rises, the baffle located in the material gap remains vertically at the angle between the side of the insulation board and the bending section under the action of gravity. After the pressing device is completely reset, the bending cylinder is activated again. The bending cylinder drives the bending die to perform a second bend on the bending section, making the bending section parallel to the side of the insulation board. At this time, the baffle is located between the bending section and the insulation board and is clamped and fixed by the bending section and the insulation board, thereby realizing the synchronous processing of baffle installation and bending, and completing the production of tongue and groove joints.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Using a bending detection device, the tongue and groove joints of the machined parts are automatically inspected during production debugging or production. The detector detects the distance difference between the baffle and the bending section, converting the distance difference into the displacement of the iron core. In conjunction with an induction coil, the distance difference is further converted into a changing induced electromotive force. The control system analyzes the change in induced electromotive force to determine whether the bending angle is qualified. If it is not qualified, the control system controls the extension of the bending cylinder to correct the bending angle, thereby achieving the purpose of automatically adjusting the bending degree.

[0022] 2. By using limit blocks and anti-tipping components in combination, the baffle to be unloaded is constrained and fixed, so that the baffle moves in an orderly manner within the pressing shell to unload the material, preventing the baffle to be unloaded from tipping over, which would cause unloading failure and blockage of the unloading slide.

[0023] 3. The traditional process of bending the baffle before manual installation is simplified by using a pressing device in conjunction with the bending assembly to achieve simultaneous baffle installation and bending. This not only reduces manpower consumption but also improves production efficiency. The pressing device is driven by a hydraulic device, and the bending assembly is driven by a bending cylinder to achieve pneumatic-hydraulic linkage.

[0024] 4. The bending and unloading device converts the displacement of the pressing device into driving force. Utilizing the attraction force of the ring magnet and the obstruction of the unloading rod, it realizes the transportation and automatic unloading of the baffle, allowing the baffle to fall accurately into the unloading gap and complete the placement of the baffle.

[0038] like Figures 1-11 As shown, the present invention provides a technical solution for a gas-hydraulic linkage type insulation board end face tongue and groove production equipment: including a base 1, baffles 9 and bending section 8. The base 1 is provided with an inner frame 2, and several conveying rollers 10 are installed on the inner frame 2. A fixed cylinder 11 is installed on the inner frame 2, and a fixed pressure rod 6 is installed on the output shaft of the fixed cylinder 11. A bending detection device 3 is installed on the base 1. A main slide rod 13 is installed on the base 1. A crossbeam 12 is installed at the top of the main slide rod 13. A hydraulic device 4 is installed on the crossbeam 12.

A bending assembly 5 is installed on the base 1. The pressing device 7 and the bending assembly 5 cooperate to bend the bending section 8. Several neatly arranged baffles 9 are provided inside the pressing device 7.

[0039] The machine is equipped with a control system, which is used to control the entire tongue and groove production equipment. The insulation board consists of a metal base plate, a metal top plate, and a filling layer. After the insulation board is cut, a fixed-width bending section 8 is generated at the metal base plate. After bending, the bending section 8 changes from horizontal to vertical. The vertical bending section 8 is used to fix the baffle 9, so that the baffle 9 fits tightly against one side of the insulation board. After bending, the width of the bending section 8 decreases, fixing the lower part of the baffle 9. The width of the baffle 9 is similar to the height of the filling layer.

[0040] The pressing device 7 includes a pressing housing 71, which is slidably connected to the main slide rod 13. The pressing housing 71 is connected to the output shaft of the hydraulic device 4. A bending and feeding device 75 is slidably installed inside the pressing housing 71. A feeding housing 79 is installed on the pressing housing 71. Several feeding rods 791 are installed inside the feeding housing 79. An electric telescopic rod 77 is installed on the pressing housing 71.

[0041] The limit block 710 is used to block the baffle 9 to be unloaded, preventing the baffle 9 from tipping over and causing unloading failure and blockage of the unloading slide 712.

[0042] The bending and unloading device 75 includes an unloading plate 752, on which racks 751 are symmetrically mounted. The racks 751 mesh with a transmission gear 74 for transmission. An annular magnet 753 is mounted on the unloading plate 752, as is an anti-tipping component 754. The unloading plate 752 is provided with unloading sliding holes 755. In the initial state, the annular magnet 753 is in contact with the baffle 9 and attracts the baffle 9.

[0043] The anti-tipping assembly 754 includes an anti-tipping housing 7541, which is mounted on a feed plate 752. An anti-tipping slide plate 7543 is installed inside the anti-tipping housing 7541, and an anti-tipping spring 7542 is installed between the anti-tipping slide plate 7543 and the anti-tipping housing 7541. The spring force of the anti-tipping spring 7542 is greater than the spring force of the limit spring 711.

[0044] The bending assembly 5 includes a bracket 53, which is mounted on a base 1. A pad 54 is mounted on the bracket 53, and several multi-stage telescopic curved rods 55 are mounted on the pad 54. A bending die 52 is mounted at one end of each multi-stage telescopic curved rod 55, and a bending head 521 is provided on the bending die 52. A bending cylinder 51 is rotatably mounted on the bracket 53, and the output shaft of the bending cylinder 51 is rotatably connected to the bending die 52. The multi-stage telescopic curved rods 55 can gradually extend and retract as the bending die 52 rotates.

[0045] The bending detection device 3 includes a second cylinder 35 and a detection motor 36. The second cylinder 35 is mounted on the base 1. A first cylinder 31 is mounted on the output shaft of the second cylinder 35. A connecting block 37 is mounted on the output shaft of the first cylinder 31. A limit slide rod 34 is installed between the connecting blocks 37. A lead screw 32 is rotatably mounted between the connecting blocks 37. The output shaft of the detection motor 36 passes through the connecting block 37 and is connected to one end of the lead screw 32. A detector 33 is slidably mounted on the limit slide rod 34. The detector 33 is threadedly connected to the lead screw 32.

[0046] The detector 33 includes a detection frame 331, which is slidably connected to a limiting slide bar 34 and threadedly connected to a lead screw 32. A crossbar 3311 is installed on the detection frame 331, a detection connecting block 336 is installed on the crossbar 3311, a coil frame 339 is installed on the detection connecting block 336, an induction coil 337 is installed on the coil frame 339, and a detection rotating rod 335 is rotatably installed on the crossbar 3311.

[0047] The detector 33 also includes a detection slide bar 332, which is slidably mounted on the detection frame 331. The detection slide bar 332 is movably connected to the detection rotating rod 335. An iron core 338 is installed at one end of the detection slide bar 332, and a pulley joint 3310 is installed at the other end of the detection slide bar 332. A detection pulley 334 is rotatably mounted on the pulley joint 3310, and a detection spring 333 is provided between the pulley joint 3310 and the detection frame 331.

[0048] The working principle of this invention is as follows: The control system first activates the hydraulic device 4. The output shaft of the hydraulic device 4 drives the pressing device 7 to descend initially. The pressing plate 78 descends to a preset height. At this time, the gap between the pressing plate 78 and the pad 54 is less than the thickness of the insulation board. The control system activates the transmission roller to transport the cut insulation board to the pressing plate 78. Since the thickness of the insulation board is greater than the gap between the pressing plate 78 and the pad 54, the insulation board cannot pass through the gap. At this time, the insulation side is in contact with the pressing plate 78. The control system activates the fixing cylinder 11. The fixing cylinder 11 drives the fixing rod 6 to descend through the output shaft. The fixing rod 6 presses the insulation board tightly and fixes it. The control system restarts the hydraulic device 4. The hydraulic device 4 drives the pressing device 7 to descend further until the pressing plate 78 presses the bent section 8 tightly.

[0049] After the lower pressure plate 78 descends to a certain height, the transmission rod 72 contacts the pad 54. As the lower pressure plate 78 descends further, the end of the transmission rod 72 is pressed and slides upward relative to the lower pressure housing 71. When the transmission rod 72 slides, it drives the transmission gear 74 to slide. Since the transmission gear 74 is rotatably connected to the lower pressure housing 71, it cannot slide. Therefore, through the threaded engagement between the transmission gear 74 and the transmission rod 72, the transmission gear 74 converts the sliding into rotation. The transmission gear 74 drives the bending and feeding device 75 to slide through the rack 751. The bending and feeding device 75 drives the attracted baffle 9 to slide along the feeding slide. The material slides within the guide rail 712. When it slides to a certain position, the end of the material feed rod 791 begins to enter the material feed sliding hole 755 on the material feed plate 752. When the baffle 9 is completely above the material feed gap 781, the material feed rod 791 just passes through the material feed sliding hole 755 and the annular magnet 753 and contacts one side of the baffle 9. As the bending material feed device 75 slides further, the baffle 9 is blocked by the material feed rod 791 and stays in place and separates from the annular magnet 753. After the baffle 9 loses the attraction force of the annular magnet 753, it falls into the material feed gap 781 under the influence of its own gravity. Finally, the baffle 9 falls on the bending section 8.

[0050] The control system activates the bending cylinder 51, and the output shaft of the bending cylinder 51 drives the bending die 52 to rotate. Under the action of the multi-stage telescopic crank 55, the bending die 52 rotates around the pad 54. The bending head 521 on the bending die 52 rotates while performing an initial bend on the bending section 8. The angle between the bending section 8 and the side of the insulation board starts to decrease from 90°. After bending to the preset angle, the control system drives the pressing device 7 to rise through the hydraulic device 4. When the pressing device 7 rises, it is located at the material feeding seam. Under the influence of gravity, the baffle 9 inside 781 remains vertically at the angle between the side of the insulation board and the bending section 8. After the pressing device 7 is fully reset, the bending cylinder 51 is opened again. The bending cylinder 51 drives the bending die 52 to perform a second bending of the bending section 8, making the bending section 8 parallel to the side of the insulation board. At this time, the baffle 9 is located between the bending section 8 and the insulation board and is clamped and fixed by the bending section 8 and the insulation board, thereby realizing the synchronous processing of the installation and bending of the baffle 9 and completing the production of the tongue and groove joint.

[0051] During the upward reset process of the pressing device 7, the transmission rod 72 gradually loses pressure and slides back to its original position under the action of the reset spring 73. The transmission rod 72 drives the transmission gear 74 to rotate in the opposite direction, thereby causing the bending and unloading device 75 to slide in the opposite direction. After the bending and unloading device 75 slides to a certain distance, the inclined surface of the anti-tilting slide plate 7543 on the anti-tilting component 754 comes into contact with the inclined surface of the limiting block 710. The anti-tilting slide plate 7543 further pushes the limiting block 710. Under the action of pressure, the limiting block 710 overcomes the elastic force of the limiting spring 711 and slides upward. When the limiting block 710 is completely slid open, the anti-tilting slide plate 7543 presses against the slide plate above the unloading baffle 9. Then, the bending and unloading device 75 slides back to its original position. The anti-tilting slide plate 7543 overcomes the elastic force of the anti-tilting spring 7542 and slides inside the anti-tilting housing 7541. After that, the annular magnet 753 slides and... The baffle 9 to be unloaded is attached and adsorbed; when unloading is performed again, the bending unloading device 75 drives the unloaded material to slide away. Since the anti-tilt slide plate 7543 is still in the retracted state, under the action of the anti-tilt spring 7542, the anti-tilt slide plate 7543 still holds the baffle 9 above the original unloaded baffle 9 to prevent it from falling. When the unloaded baffle 9 slides away from the position of the limit block 710, the anti-tilt slide plate 7543 also gradually returns to its original position and slides away with the bending unloading device 75. The baffle 9 above the original unloaded baffle 9 loses its restraint and falls into the unloading slide 712. At this time, the limit block 710 returns to its original position under the action of the limit spring 711 and blocks the baffle 9 that has just fallen into the unloading slide 712 to prevent it from tipping over. Then the output shaft of the electric telescopic rod 77 drives the pusher plate 76 to move slightly, so that the neatly arranged upper baffle 9 is pressed tightly.

[0052] During production debugging or product sampling inspection, after bending is completed, the control system activates the bending detection device 3. The bending detection device 3 adjusts the position of the detector 33 via the first cylinder 31 and the second cylinder 35, so that the two detection pulleys 334 on the detector 33 are respectively in contact with the baffle 9 and the bending section 8. During contact, due to the distance difference between the sides of the baffle 9 and the bending section 8, under the condition of qualified tongue and groove joint, the lower detection pulley 334 will first contact the bending section 8. As the detector 33 extends further forward, the lower detection pulley 334 drives the lower detection slide rod 332 to overcome the elastic force of the detection spring 333 and retract towards the detection frame 331 through the pulley joint 3310. The lower detection slide rod 332 drives the detection rotating rod 335 to rotate on the crossbar 3311. The detection rotating rod 335 drives the upper detection slide rod 332 to extend, and the upper detection slide rod 332 drives the upper detection pulley 334 to extend until the upper detection pulley 334 is in contact with the unbent section. When the baffle 9 partially covers section 8 and slides at the top and bottom, the iron core 338 on it moves into or away from the corresponding induction coil 337. When the iron core 338 moves within the induction coil 337, it generates an induced electromotive force. At the same speed, the longer the iron core 338 extends into the coil, the greater the induced electromotive force. The control system analyzes the change in the electromotive force of the upper and lower induction coils 337 to determine the distance difference between the baffle 9 and the bending section 8. When the distance difference is within the error range, it indicates that the bending quality is qualified. When the distance difference is too large and positive, it indicates that the bending angle is too small, and the baffle 9 and the bending section 8 are loose, which may lead to problems such as falling off. Conversely, when the distance difference is too large and negative, it indicates that the bending angle is too large, which may cause the side of the insulation board and the baffle 9 to be dented and deformed. The control system controls the extension of the bending cylinder 51 to correct the bending angle, thereby achieving the purpose of automatically adjusting the bending degree.
