Description

Technical Field

[0001] This invention relates to the field of floor slab sound insulation board processing technology, specifically to a composite processing device and method for hollow structure floor slab sound insulation boards. Background Technology

[0002] The hollow-structure floor slab sound insulation board is a new type of sound insulation board developed by the applicant, such as... Figure 1 As shown, it is composed of an upper layer of high-density polyvinyl chloride board, a middle layer of polycarbonate hollow board, and a lower layer of modified polypropylene thermal insulation and sound insulation board bonded together. It is used in the construction of floor slabs and has excellent thermal insulation and sound insulation performance.

[0003] Hollow core floor slabs with sound insulation panels are bonded together using adhesive. After bonding, adhesive overflow is prone to occur on the sides under the pressure of the pressing equipment. Traditionally, composite panels are polished by using scrapers on both sides of the equipment or milling cutters to grind the cured adhesive on the edges. However, in actual production, due to the special nature of the hollow core floor slab sound insulation panel material, scraping with a scraper can easily pull out material from the side of the modified polypropylene insulation panel, which is a foamed material, causing pits on the edge of the panel and affecting product quality. Similarly, milling the cured adhesive on the edges can cause the high-density polyvinyl chloride (PVC) board to melt and shrink due to the high temperature during polishing, also affecting product quality.

[0004] To ensure product quality, the current method primarily involves manual wiping with a sponge roller / brush dipped in adhesive remover. However, this method requires a large amount of manual labor, resulting in low processing efficiency. Furthermore, after wiping each section of the board, the sponge roller / brush needs to be cleaned and re-dipped in adhesive remover, making the process cumbersome and the effectiveness of adhesive removal difficult to guarantee. Therefore, a composite processing device and method for hollow-structure floor slab sound insulation panels is needed to solve these problems. Summary of the Invention

The scraping assembly is automatically controlled to start and reset according to the rotation speed of the wiping wheel.

[0007] Preferably, the wiping wheel includes a wiping wheel shaft and a wiping layer. The wiping wheel shaft is rotatably connected to a rotating frame, and the wiping layer is annularly wrapped around the wiping wheel shaft for absorbing adhesive removal solvent to wipe the sides of the sound insulation board of the hollow structure floor slab. A switching motor is installed at the bottom of the side support, and the switching motor is used to drive the rotating frame to rotate.

[0008] Preferably, the housing is slidably connected to the side support via a sliding block at its lower end. The housing has a hollow semi-cylindrical structure, and two housings can be spliced ​​together to form a complete internal hollow cylinder, creating a sealed cleaning space. The bottom of the housing is provided with a drain hole for discharging the cleaning fluid out of the housing. The upper and lower sides of the wiping wheel shaft are rotatably connected with sealing rings.

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Please see Figure 1-9 The present invention provides the following technical solutions: A composite processing device for hollow structure floor slab sound insulation board includes: a frame 1, with side supports 4 installed on the front and rear sides of the frame 1, the side supports 4 being used to install a wiping and adhesive removal component 5 and an adhesive removal component cleaning mechanism 6.

[0029] A conveying mechanism 2, mounted on a frame 1, is used to convey the sound insulation panels of the hollow-core floor slab. A conveying drive assembly 3, providing power to the conveying mechanism 2, is mounted on one side of the frame 1. The conveying mechanism 2 includes several linearly arranged conveying rollers 21 and a conveyor belt 22, with the conveyor belt 22 mounted on the conveying rollers 21. The conveying drive assembly 3 includes a transmission box 31 and a conveying motor 32. The transmission box 31 is mounted on the frame 1, and its output end is connected to the conveying rollers 21. The conveying motor 32 is mounted on the input end of the transmission box 31. To further ensure the conveying stability of the sound insulation panels of the hollow-core floor slab, a downward conveying structure can be installed above the conveying mechanism 2; the specific configuration can be determined according to actual needs.

[0030] The adhesive removal assembly 5 is mounted on the side bracket 4 and is used to remove excess adhesive from the sides of the sound insulation board of the hollow structure floor slab using solvent wiping. The assembly includes a rotating frame 51 for mounting wiping wheels. The center of the rotating frame 51 is rotatably connected to the side bracket 4 via a rotating shaft. Two or more wiping wheels are provided and are equidistantly distributed on the rotating frame 51 about its rotation axis. Rotation of the rotating frame 51 allows for switching between the wiping wheels. A switching motor 54 is mounted at the bottom of the side bracket 4 to drive the rotating frame 51 to rotate.

[0031] The wiping wheel includes a wiping wheel shaft 52 and a wiping layer 53. The wiping wheel shaft 52 is rotatably connected to the rotating frame 51. The wiping layer 53 is annularly wrapped around the wiping wheel shaft 52 and is used to absorb adhesive remover and wipe the sides of the sound insulation board of the hollow structure floor slab. The wiping layer 53 is made of a flexible absorbent material, such as sponge or cotton cloth. In this embodiment, two wiping wheels are provided and symmetrically arranged at both ends of the rotating frame 51. The two wiping wheels can be switched by rotating the rotating frame 51 180°.

[0032] The adhesive removal component cleaning mechanism 6 is mounted on the side bracket 4 and is used to clean the wiping wheel and replenish the adhesive removal solvent. The adhesive removal component cleaning mechanism 6 includes two housings 61 for constructing a cleaning space. The housings 61 are slidably connected to the side bracket 4 via sliding blocks 67 at their lower ends. The housings 61 have a hollow semi-cylindrical structure. The two housings 61 can be spliced ​​together to form a complete hollow cylinder, creating a sealed cleaning space.

[0033] A rinsing head 62 is mounted on the housing 61. The rinsing head 62 is equipped with several nozzles, which are located inside the housing 61 and face the wiping wheel. The rinsing head 62 is used to supply cleaning fluid and adhesive remover. The supply equipment uses a booster pump, which is a conventional technology, to deliver the cleaning fluid or adhesive remover to the rinsing head 62 and spray it onto the surface of the wiping layer 53.

[0034] The bottom of the housing 61 is provided with a drain hole 66 for draining the cleaning fluid out of the housing 61. The upper and lower sides of the wiping wheel shaft 52 are rotatably connected with sealing rings 68. The sealing rings 68 are used to press and seal with the housing 61 and ensure the normal rotation of the wiping wheel shaft 52. The outer wall of the sealing rings 68 is made of rubber to improve the sealing performance after it is pressed with the housing 61 and to prevent water leakage when rinsing the wiping layer 53.

[0035] A drive assembly 63 for moving the two housings 61 closer together or further apart is mounted on the bottom of the side bracket 4. The drive assembly 63 includes a rack 631 mounted on a sliding block 67, a motor bracket 632 mounted on the bottom of the side bracket 4, and a drive motor 633 mounted on the motor bracket 632. A keyed gear 634 is connected to the output end of the drive motor 633, meshing with the rack 631 to drive the two housings 61 to move closer together or further apart. The two racks 631 mesh with the two sides of the gear 634 respectively, and the rotation of the drive motor 633 drives the two housings 61 to move closer or further apart. When the two housings 61 are far apart, it facilitates switching the wiping rollers; when the two housings 61 are close together and in contact, the wiping rollers enter the cleaning space.

[0036] A rotary drive assembly 64 for driving the wiping wheel to rotate is installed on the upper end of the housing 61, used for the rotation cleaning and dehydration of the wiping wheel. The rotary drive assembly 64 includes a mounting frame 641 mounted on the upper surface of the housing 61, on which a rotary drive motor 642 is mounted upside down. The output end of the rotary drive motor 642 is keyed to a drive gear 643; a driven gear 644 is keyed to the wiping wheel shaft 52. When the two housings 61 are in contact, the driven gear 644 meshes with the drive gear 643. The rotary drive motor 642 is speed-adjustable, controlling the rotation speed of the wiping wheel. When the wiping wheel is running at a low speed (e.g., below 30 rpm), it can be rinsed; when the wiping wheel is running at a high speed (e.g., above 800 rpm), it can be dehydrated, and the scraping assembly 65 can scrape and squeeze the surface of the wiping wheel to further improve the dehydration and cleaning effect.

[0037] A scraping assembly 65 is installed inside the housing 61. The scraping assembly 65 is used to scrape off impurities on the surface of the wiping wheel and assist in squeezing and dehydrating. The scraping assembly 65 is automatically controlled to start and reset according to the rotation speed of the wiping wheel. The scraping assembly 65 includes a mounting groove 651 fixedly installed on the inner wall of the housing 61, a scraper 652, and a guide strip 653. The scraper 652 is laterally slidably connected in the mounting groove 651. A tension spring is provided in the mounting groove 651 to pull the scraper 652 into the mounting groove 651, so that the scraper 652 is initially in a retracted state.

[0038] A connecting rod 654 is rotatably connected to the outer wall of the mounting groove 651. Both the upper and lower ends of the connecting rod 654 are provided with straight grooves. The rod on the scraper 652 is slidably connected to the lower end of the connecting rod 654 in the straight groove. A guide bar 653 is horizontally slidably connected inside the housing 61. The two guide bars 653 can form a complete circular track. The rod on the guide bar 653 is slidably connected to the upper end of the connecting rod 654 in the straight groove. The sliding of the guide bar 653 can drive the scraper 652 to slide in the opposite direction.

[0039] An inertial drive assembly for pushing the guide bar 653 is mounted on the wiping wheel shaft 52. The inertial drive assembly includes a mounting ring 655, an arc-shaped block 656, and a roller 657, all keyed to the wiping wheel shaft 52. The arc-shaped block 656 is symmetrically rotatably mounted on both sides of the mounting ring 655. The roller 657 is rotatably connected to the end of the arc-shaped block 656 away from the wiping wheel shaft 52. A torsion spring is provided at the connection between the arc-shaped block 656 and the mounting ring 655. The purpose of this torsion spring is to ensure that the arc-shaped block 656 is initially in a contracted state and automatically resets after rotation. A counterweight is provided at the end of the arc-shaped block 656 away from the wiping wheel shaft 52. When the wiping wheel shaft 52 rotates at a high speed, the arc-shaped block 656 rotates under the action of inertial force, thereby pushing the guide bar 653 and causing the scraper 652 to slide outward, thus scraping and squeezing the wiping layer 53.

[0040] This invention also provides a method for removing adhesive from the side of a sound insulation board in a hollow structure floor slab, comprising the following steps: S1: Place the sound insulation board of the hollow structure floor slab after bonding and bonding onto the conveying mechanism 2, and start the conveying mechanism 2 to convey the sound insulation board of the hollow structure floor slab. S2: When the hollow structure floor slab sound insulation board is delivered to the wiping and adhesive removal component 5, the wiping layer 53, which absorbs adhesive removal solvent, wipes and dissolves the excess adhesive on the side of the hollow structure floor slab sound insulation board. S3: Place two adjacent hollow structure floor slab sound insulation boards on the conveying mechanism 2 at intervals. After the side of the previous hollow structure floor slab sound insulation board is wiped and the adhesive is removed, during the conveying interval, the rotating frame 51 rotates and switches the clean wiping wheel to the working position to wipe and remove the adhesive from the next hollow structure floor slab sound insulation board. S4: During the wiping and adhesive removal process of the sound insulation board of the next hollow structure floor slab, the adhesive removal component cleaning mechanism 6 cleans, scrapes, dehydrates and absorbs the adhesive removal solvent of the previous wiping wheel to complete the maintenance of the wiping wheel; S5: Rotating frame 51 switches the wiping wheel again to ensure that each hollow structure floor slab sound insulation board is wiped and de-adhesive is removed using a clean wiping wheel. This process is repeated to complete the side de-adhesive removal process of the hollow structure floor slab sound insulation board.

[0041] The specific working process of the processing device in this invention is as follows: First, the hollow structure floor slab sound insulation boards are placed at intervals on the conveying mechanism 2. The conveying mechanism 2 is started to convey the hollow structure floor slab sound insulation boards. When the hollow structure floor slab sound insulation boards pass the position of the wiping and de-adhesive component 5, the wiping layer 53, which absorbs the de-adhesive solvent, wipes and dissolves the excess adhesive on the side of the hollow structure floor slab sound insulation boards, thereby achieving the de-adhesive treatment.

[0042] After the sound insulation panel of the hollow structure floor slab is processed, the switching motor 54 drives the rotating frame 51 to rotate 180°, switching the used wiping wheel to the cleaning position and the clean wiping wheel to the working position. The opening and closing drive motor 633 starts and drives the opening and closing gear 634 to rotate. The opening and closing gear 634 drives the two housings 61 to move closer to each other and fit together through the rack 631, wrapping the used wiping wheel inside. At this time, the driving gear 643 meshes with the driven gear 644 on the wiping wheel shaft 52.

[0043] First, the wiping wheel is driven to rotate at a low speed (e.g., 20 rpm) by a rotary drive motor 642, while clean water is supplied to the rinsing head 62 by a booster pump to rinse the wiping layer 53. After rinsing, the speed of the rotary drive motor 642 is increased, causing the wiping wheel to rotate at a high speed (e.g., 1000 rpm). The wiping layer 53 is dehydrated under the action of high-speed rotation. During this process, the arc-shaped block 656 unfolds under the action of inertia and pushes the guide strip 653. The connecting rod 654 drives the scraper 652 to move towards the wiping layer 53, squeezing the wiping layer 53 to remove impurities from its surface and aiding in dehydration through squeezing. Once the wiping layer 53 is cleaned and dehydrated, the wiping wheel switches back to low-speed rotation, the scraper 652 disengages from the wiping layer 53, and a desiccant is delivered to the flushing head 62 via a booster pump and evenly sprayed onto the surface of the wiping layer 53. After the wiping layer 53 absorbs the desiccant, maintenance is complete, and the next wiping and desiccant removal process can begin. Repeating this process allows for continuous, high-quality wiping and desiccant removal of the hollow-core floor slab sound insulation panels.

[0044] 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.

After the side of the previous hollow structural floor slab sound insulation board is wiped and the adhesive is removed, during the conveying interval, the rotating frame (51) rotates and switches the clean wiping wheel to the working position to wipe and remove the adhesive from the next hollow structural floor slab sound insulation board. S4: During the wiping and de-adhesive removal process of the sound insulation board of the next hollow structure floor slab, the de-adhesive removal component cleaning mechanism (6) cleans, scrapes, dehydrates and absorbs the de-adhesive solvent of the previous wiping wheel to complete the maintenance of the wiping wheel; S5: The rotating frame (51) switches the wiping wheel again to ensure that each hollow structure floor slab sound insulation board is wiped and de-adhesive is removed using a clean wiping wheel. This process is repeated to complete the side de-adhesive removal process of the hollow structure floor slab sound insulation board.
