Description

Technical Field

[0001] This invention relates to the field of heat insulation board production technology, specifically a production process for a fireproof heat insulation board. Background Technology

[0002] Building ventilation and smoke extraction require the use of ducts, which are usually made of fireproof boards spliced ​​together. The fireproof boards include a base plate and a color steel plate. The base plate is made of magnesium crystalline silicon board, and the color steel plate is attached to the base plate with glue. The color steel plate can improve the service life of the insulation board.

[0003] The common production process for fireproof and heat-insulating boards involves conveying, gluing, attaching, and cutting. Glue is applied to the color steel plate, which is then attached to the base plate to complete the attachment process, ultimately resulting in the desired fireproof and heat-insulating board. During attachment, two rotating rollers are used. The color steel plate with glue and the base plate enter the two rotating rollers together, and the two rotating rollers tightly attach the color steel plate to the base plate.

[0004] Regarding the above technical conditions, there is also the problem that when the rotating roller rolls the fireproof and heat-insulating board, excess glue will be squeezed out and stick to the rotating roller. Over time, this will cause the surface of the rotating roller to become uneven, thus affecting the tightness of the adhesion between the color steel plate and the base plate.

[0005] Based on this, the present invention designs a production process for fireproof and heat-insulating panels to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a manufacturing process for fireproof and heat-insulating panels to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a production process for a fireproof and heat-insulating board, comprising the following steps: Step 1, feeding the board, placing the base plate on a conveying device for conveying; Step 2, applying adhesive, applying adhesive to the color steel plate; Step 3, attaching, attaching the color steel plate to the base plate using an attaching device; Step 4, removing adhesive, removing the adhesive residue on the attaching device using an adhesive removal device; Step 5, cutting, cutting the base plate with the attached color steel plate; The attaching device in Step 3 includes a fixed frame, an upper conveying roller, a rotating shaft, and a lower conveying roller. The upper conveying roller is rotatably mounted on the fixed frame, a first motor is fixedly mounted on the fixed frame, the rotating shaft is coaxially fixedly mounted on the first motor, and an mounting plate is fixedly mounted on the rotating shaft. The lower conveying roller is rotatably mounted on the mounting plate, and multiple lower conveying rollers are circumferentially arranged on the mounting plate. The base plate is located between the upper rotating roller and the lower conveying roller. When the color steel plate passes between the upper rotating roller and the lower conveying roller, the color steel plate is attached to the base plate.

[0008] By adopting the above technical solution, when the color steel plate is attached to the base plate, the upper conveyor roller guides the color steel plate, and at the same time, the upper conveyor roller touches the color steel plate downward, while the lower conveyor roller touches the base plate upward, allowing the color steel plate to adhere to the base plate. Multiple lower conveyor rollers contact the base plate separately, which can increase the contact area of ​​the lower conveyor rollers and prevent the glue from constantly contacting the same roller when it flows down, thereby reducing the glue protrusions on the surface of the lower conveyor rollers and achieving the effect of improving the tightness of the adhesion between the color steel plate and the base plate.

[0009] Preferably, the adhesive removal in step 4 includes the following steps: wiping, immersion, and wiping again. The adhesive removal device includes a cleaning box, a wiping section, a washing section, and a wiping machine. The cleaning box is fixedly mounted on a fixed frame, and the lower rotating roller is located in the cleaning box. The wiping section includes a first conveyor belt, a first guide roller, a second guide roller, and a wiping cloth. The first and second guide rollers are rotatably mounted on the cleaning box, and the first conveyor belt is driven and sleeved on the first and second guide rollers. The wiping cloth is fixedly mounted on the first conveyor belt and is in contact with the lower conveyor roller. The cleaning section includes a partition and a cleaning cloth. The partition is fixedly mounted on the bottom of the cleaning box. There are two partitions, and the cleaning cloth is fixedly connected to the two partitions. The lower conveyor roller is in contact with the cleaning cloth. Adhesive remover is filled between the two partitions. When the lower conveyor roller is at the bottom, it is immersed in the adhesive remover. The wiping machine includes a drying cloth and a connecting plate. The connecting plate is located in the processing box, and the drying cloth is fixedly mounted on the connecting plate and is in contact with the lower conveyor roller.

[0010] By adopting the above technical solution, the adhesive removal device removes adhesive from the lower conveyor roller. The wiping cloth first wipes away most of the adhesive adhering to the conveyor roller. When the conveyor roller enters between the two partitions, the adhesive remover cleans the adhesive, and at the same time, the cleaning cloth rubs against the surface of the lower conveyor roller to further remove the adhesive. The drying cloth wipes the lower conveyor roller to dry the remaining adhesive remover, thus achieving the effect of removing adhesive from the lower conveyor roller.

[0011] Preferably, a placement plate is fixedly mounted on the processing box, a first telescopic spring is mounted on the placement plate, a fixing plate is fixedly mounted on the first telescopic spring, a second motor is fixedly mounted on the fixing plate, a first rotating rod is coaxially fixedly mounted on the shaft of the second motor, the first rotating rod is coaxially fixedly connected to a first guide roller, a receiving plate is fixedly mounted on the cleaning box, a second telescopic spring is fixedly mounted on the receiving plate, an mounting cylinder is fixedly mounted on the second telescopic spring, the mounting cylinder is sleeved on the first guide roller, a first limiting hole is opened on the fixing plate, a first limiting rod is vertically fixedly mounted on the placement plate, the first limiting rod is located in the first limiting hole, a second limiting rod is vertically fixedly mounted on the receiving plate, a second limiting hole is vertically opened on the mounting cylinder, the second limiting rod is located in the second limiting hole.

[0012] By adopting the above technical solution, when the lower conveyor roller comes into contact with the wiping cloth, the first and second telescopic springs can make the wiping cloth press against the rotating roller, allowing the wiping cloth to fully contact the lower conveyor roller and wipe off the adhesive on the lower conveyor roller.

[0013] Preferably, a third telescopic spring is fixedly installed at the bottom of the cleaning box, and the third telescopic spring is fixedly connected to the cleaning cloth.

[0014] By adopting the above technical solution, when the lower conveyor roller comes into contact with the cleaning cloth, the third telescopic spring can make the cleaning cloth more fully contact the lower conveyor roller, thereby improving the wiping effect.

[0015] Preferably, a fourth telescopic spring is fixedly installed on the upper part of the cleaning box, and the fourth telescopic spring is fixedly connected to the drying cloth.

[0016] By adopting the above technical solution, when the lower conveyor roller comes into contact with the wiping cloth, the fourth telescopic spring can make the cleaning cloth more fully contact the lower conveyor roller, thereby improving the wiping effect.

[0017] Preferably, a scraper is fixedly installed in the processing box, and the scraper abuts against the wiping cloth.

[0018] By adopting the above technical solution, the scraper can scrape off the glue residue on the wiping cloth when it comes into contact with the wiping cloth, thus reducing the amount of glue residue left on the wiping cloth.

[0019] Preferably, multiple upper conveying rollers are provided, and a scraper is fixedly provided on the upper conveying roller at the very end. Two scraper plates are provided accordingly, and the bottom plate is located between the two scraper plates. The scraper plate abuts against the side wall of the bottom plate.

[0020] By adopting the above technical solution, after the color steel plate is attached to the base plate, the scraper can remove the glue on the base plate and the side wall of the color steel plate, reducing the amount of glue residue on the base plate and the side wall of the color steel plate.

[0021] Preferably, a first air blowing pipe is fixedly installed on the fixing frame. The first air blowing pipe is located above the wiping cloth, and a first air blowing slit is opened on the first air blowing pipe, with the first air blowing slit facing the downward conveying roller.

[0022] By adopting the above technical solution, after the lower conveyor roller is separated from the wiping cloth, the first air slit blows air onto the lower conveyor roller to dry the adhesive residue on the lower conveyor roller.

[0023] Preferably, a second air blowing pipe is fixedly installed on the fixed frame, and a second air blowing slit is opened on the second air blowing pipe. The second air blowing slit faces the color steel plate, and the second air blowing pipe blows air onto the color steel plate after it passes through the upper conveyor roller.

[0024] By adopting the above technical solution, the second air-blowing seam blows air onto the attached base plate, accelerating the drying of the adhesive on the side wall of the base plate and reducing the amount of adhesive residue on the side wall in subsequent processes.

[0025] In summary, this application has the following beneficial technical effects: the adhesive removal device removes adhesive from the lower conveyor roller. The wiping cloth first wipes away most of the adhesive adhering to the conveyor roller. When the conveyor roller enters between the two partitions, the adhesive remover cleans the adhesive, and at the same time, the cleaning cloth rubs against the surface of the lower conveyor roller to further remove the adhesive. The drying cloth wipes the lower conveyor roller to dry the remaining adhesive remover, thus achieving the effect of removing adhesive from the lower conveyor roller. Attached Figure Description

There are two corresponding mounting plates 14. The base plate 3 is located between the upper rotating roller 11 and the lower conveying roller 7. When the color steel plate 2 passes between the upper rotating roller 11 and the lower conveying roller 7, the upper conveying roller 5 abuts against the color steel plate 2, while the lower conveying roller 7 abuts against the base plate 3, so that the color steel plate 2 is attached to the base plate 3.

[0047] Reference Figures 1-13 Step 4, the adhesive removal process, includes the following steps: wiping, immersion, and wiping again. The adhesive removal device includes a cleaning box 20, a wiping section 21, a washing section 22, and a wiping cloth 23. The cleaning box 20 is fixedly mounted on a fixed frame 4, and the lower rotating roller 11 is located in the cleaning box 20.

[0048] Reference Figures 1-13The first conveyor belt 24 is driven and sleeved on the first guide roller 25 and the second guide roller 26. The wiping cloth 27 is fixedly installed on the first conveyor belt 24. The first motor 13 drives the rotating shaft 6 to rotate, thereby driving the first guide roller 25 to rotate, and the wiping cloth 27 to rotate. The wiping cloth 27 comes into contact with the lower conveyor roller 7.

[0049] Reference Figures 1-13 The cleaning unit includes partitions 38 and a cleaning cloth 39. Two partitions 38 are fixedly mounted on the bottom of the cleaning box 20. The cleaning cloth 39 is fixedly connected to both partitions 38 at both ends. A third telescopic spring 40 is fixedly mounted on the bottom of the cleaning box 20 and is fixedly connected to the cleaning cloth 39. The lower conveyor roller 7 is in contact with the cleaning cloth 39. Adhesive remover is filled between the two partitions 38. When the lower conveyor roller 7 is at its lowest position, it is immersed in the adhesive remover, and the cleaning cloth 39 is also immersed in the adhesive remover.

[0050] Reference Figures 1-13 The wiping machine 23 includes a wiping cloth 41 and a connecting plate 42. A fourth telescopic spring 43 is fixedly installed on the inner side wall of the cleaning box 20. The fourth telescopic spring 43 is fixedly connected to the connecting plate 42. The wiping cloth 41 is fixedly installed on the connecting plate 42. The wiping cloth 41 contacts the lower conveying roller 7 after contacting the adhesive remover. The lower conveying roller 7 removes the adhesive in the wiping section 21, is immersed in the cleaning section 22, and removes excess adhesive remover in the wiping machine 23.

[0051] Reference Figures 1-13 Multiple conveyor rollers 9 convey the base plate 3. When the color steel plate 2 is attached, the color steel plate 2 and the base plate 3 enter together between the upper conveyor roller 5 and the lower conveyor roller 7. The lower conveyor roller 7 abuts against the base plate 3, while the upper conveyor roller 5 abuts against the color steel plate 2, attaching the color steel plate 2 coated with glue to the base plate 3. In order to ensure sufficient glue application, a large amount of glue is generally applied to the color steel plate 2. During attachment, excess glue on the color steel plate 2 is squeezed out from both sides and flows onto the lower conveyor roller 7. Multiple lower conveyor rollers 7 contact the base plate 3 respectively, which can increase the contact area of ​​the lower conveyor rollers 7 and prevent the glue from continuously contacting the same roller when flowing down, thereby reducing glue protrusions on the surface of the lower conveyor rollers 7.

[0052] Reference Figures 1-13After the lower conveyor roller 7 contacts the base plate 3, the rotating shaft 6 rotates, causing the lower conveyor roller 7 to rotate. The lower conveyor roller 7 then contacts the wiping cloth 27. At this time, the wiping cloth 27, under the resistance of the first telescopic spring 29 and the second telescopic spring 34, makes closer contact with the lower conveyor roller 7. When it detaches from the wiping cloth 27, the lower conveyor roller 7 has rotated at least once. The wiping cloth 27 can wipe the lower conveyor roller 7, removing most of the glue residue on the lower conveyor roller 7 and reducing glue residue on the conveyor roller. As the rotating shaft 6 continues to rotate, the lower conveyor roller 7 detaches from the contact with the wiping cloth 27 and enters between the two partitions 38. At this time, the lower conveyor roller 7 comes into contact with the adhesive remover. The cleaning cloth 39 comes into contact with the lower conveyor roller 7 under the resistance of the third spring. When the lower conveyor roller 7 is at the bottom, the lower conveyor roller 7 is completely immersed in the adhesive remover.

[0053] Reference Figures 1-13 The adhesive remover removes the glue on the lower conveyor roller 7, and the cleaning cloth 39 further wipes away any remaining glue. When the lower conveyor roller 7 is removed from the cleaning cloth 39, it rotates at least once on the cleaning cloth 39, further wiping away the glue on the lower conveyor roller 7. As the rotating shaft 6 continues to rotate, the lower conveyor roller 7 disengages from the cleaning cloth 39, and under the action of the fourth spring, the drying cloth 41 presses tightly against the lower conveyor roller 7, wiping away the adhesive remover remaining on the lower conveyor roller 7. When the lower conveyor roller 7 is removed from the drying cloth 41, it rolls at least once on the drying cloth 41. As the rotating shaft 6 rotates, the lower conveyor roller 7 presses against the base plate 3 again for the next round of adhesion, and so on. By removing the glue from the lower conveyor roller 7 through the adhesive removal device, the amount of glue residue on the lower conveyor roller 7 is further reduced, thereby reducing the formation of protrusions on the lower conveyor roller 7 due to excessive glue adhesion, thus improving the adhesion tightness between the color steel plate 2 and the base plate 3.

[0054] Reference Figures 1-13 Under the resistance of the fifth telescopic spring 17, the lower conveyor roller 7 can more fully contact the color steel plate 2, allowing the color steel plate 2 to adhere more fully to the base plate 3. When the lower conveyor roller 7 contacts the base plate 3 at its highest point, the two adjacent lower conveyor rollers 7 also contact the base plate 3 under the action of the fifth telescopic spring 17. At the same time, the linear speed of the lower conveyor roller 7 rotating around the rotating shaft 6 is more than twice the moving speed of the base plate 3. For example, when the moving speed of the base plate 3 is 10 cm / s, its distance moved in one second is 10 cm. Then, the linear speed of the lower conveyor roller 7 rotating around the rotating shaft 6 is at least 20 cm / s, and its arc length moved in one second is at least 20 cm. When the color steel plate 2 is being attached, it can be ensured that the lower conveyor roller 7 is in full contact with the base plate 3, thereby allowing the color steel plate 2 and the base plate 3 to be tightly attached. When the color steel plate 2 is being attached, the rotating roller 11 and the conveyor roller 9 contact the attached fireproof plate, thereby driving the movement of the base plate 3.

[0055] Reference Figures 1-13 A scraper plate 44 is fixedly installed on the upper conveyor roller 5 near the rotating roller 11. Two scraper plates 44 are correspondingly provided. The base plate 3 and the color steel plate 2 pass between the two scraper plates 44. The scraper plates 44 abut against the side wall of the base plate 3. When the color steel plate 2 is attached to the base plate 3, some glue is squeezed out onto the side wall of the base plate 3. The scraper plates 44 can scrape off the glue on the side wall of the base plate 3 and the color steel plate 2, reducing glue residue on the side wall of the base plate 3 and the color steel plate 2. A baffle is fixedly installed on the first horizontal plate 8. The baffle abuts against the scraper plate 44. The baffle can scrape off the glue on the scraper plate 44, reducing glue accumulation on the scraper plate 44.

[0056] Reference Figures 1-13 A scraper 45 is fixedly installed in the processing box. In this embodiment, the scraper 45 is made of plastic and has a certain degree of toughness. When the wiping cloth 27 descends, the plastic scraper 45 can be deflected to a certain extent. When the wiping cloth 27 moves up, the scraper 45 returns to its original position and abuts against the wiping cloth 27, which can scrape off the glue residue on the wiping cloth 27 and reduce the amount of glue residue on the wiping cloth 27.

[0057] Reference Figures 1-13 A first air pipe 46 is fixedly installed on the fixed frame 4. The first air pipe 46 is located above the wiping cloth 41. A first air slit is opened on the first air pipe 46, which faces the lower conveying roller 7. An air supply pipe is installed on the first air pipe 46, and an air pump is connected to the air supply pipe. After the lower conveying roller 7 is separated from the wiping cloth 41, the first air slit blows air onto the lower conveying roller 7 to dry the adhesive residue on the lower conveying roller 7.

[0058] Reference Figures 1-13 A second air blowing pipe 47 is fixedly installed on the fixing frame 4. An air supply pipe is also connected to the second air blowing pipe 47, and an air pump is connected to the air supply pipe. A second air blowing slit is opened on the second air blowing pipe 47, which faces the color steel plate 2. The second air blowing pipe 47 blows air onto the color steel plate 2 after it has passed through the upper conveyor roller 5. The second air blowing slit blows air onto the attached base plate 3, which speeds up the drying of the glue on the side wall of the base plate 3 and reduces the amount of glue residue on the side wall of the base plate 3 in subsequent processes.

[0059] The implementation principle of this embodiment is as follows: Multiple conveying rollers 9 convey the base plate 3. When the color steel plate 2 is attached, the color steel plate 2 and the base plate 3 enter together between the upper conveying roller 5 and the lower conveying roller 7. The lower conveying roller 7 abuts against the base plate 3, while the upper conveying roller 5 abuts against the color steel plate 2, attaching the color steel plate 2 coated with glue to the base plate 3. In order to ensure the impact of glue application, a large amount of glue is generally applied to the color steel plate 2. During attachment, the excess glue on the color steel plate 2 is squeezed down through both sides. Multiple lower conveying rollers 7 contact the base plate 3 respectively, which can increase the contact area of ​​the lower conveying rollers 7 and prevent the glue from always contacting the same roller when it flows down, thereby reducing the glue sticking protrusions on the surface of the lower conveying rollers 7.

[0060] After the lower conveyor roller 7 contacts the base plate 3, the rotating shaft 6 rotates, driving the conveyor roller to rotate. The conveyor roller contacts the wiping cloth 27. At this time, the wiping cloth 27, under the resistance of the first telescopic spring 29 and the second telescopic spring 34, contacts the lower conveyor roller 7 more tightly. When it detaches from the wiping cloth 27, the lower conveyor roller 7 has rotated at least once. The wiping cloth 27 can wipe the lower conveyor roller 7, removing most of the glue residue on the lower conveyor roller 7 and reducing glue residue on the conveyor roller. As the rotating shaft 6 continues to rotate, the lower conveyor roller 7 detaches from the contact with the wiping cloth 27 and enters between the two partitions 38. At this time, the lower conveyor roller 7 contacts the adhesive remover. The cleaning cloth 39 contacts the lower conveyor roller 7 under the resistance of the third spring. When the lower conveyor roller 7 is at the bottom, the lower conveyor roller 7 is completely immersed in the adhesive remover.

[0061] The adhesive remover removes the glue on the lower conveyor roller 7, and the cleaning cloth 39 further wipes away any remaining glue. When the lower conveyor roller 7 is removed from the cleaning cloth 39, it rotates at least once on the cleaning cloth 39, further wiping away the glue on the lower conveyor roller 7. As the rotating shaft 6 continues to rotate, the lower conveyor roller 7 disengages from the cleaning cloth 39. At the same time, under the action of the fourth spring, the drying cloth 41 presses tightly against the lower conveyor roller 7, wiping away the adhesive remover remaining on the lower conveyor roller 7. When the lower conveyor roller 7 is removed from the drying cloth 41, it rolls at least once on the drying cloth 41. As the rotating shaft 6 rotates, the lower conveyor roller 7 presses against the base plate 3 again for the next round of adhesion, and so on. By removing the glue from the lower conveyor roller 7 through the adhesive removal device, the amount of glue residue on the lower conveyor roller 7 is further reduced, thereby reducing the formation of protrusions on the lower conveyor roller 7 due to excessive glue adhesion, thus improving the adhesion tightness between the color steel plate 2 and the base plate 3.
