Description

Technical Field

[0001] The invention relates to waterproof backing plate production equipment, and more specifically, to a fully automated production equipment for waterproof backing plates. Background Art

[0002] Extruded board is one of the most commonly used thermal insulation materials in the building decoration industry, but its disadvantages are low tensile strength, flammability and easy deformation. In order to improve these disadvantages, some German manufacturers have coated cement mortar on both sides of extruded board in recent years to make waterproof backing boards, which are widely used in moisture-proofing, thermal insulation, heat insulation of interior and exterior walls of buildings, and wall and floor substrates and waterproofing.

[0003] The current production process of waterproof backing boards is segmented, and the specific process is as follows: first, one side of the extruded board is scraped with slurry and placed on a rack for curing. After solidification, it is turned over and scraped with slurry again and cured. After both sides are solidified, they are cut into sizes that are convenient for construction. There are currently two specifications, namely length 1200mm*width 600mm or length 2440mm*width 1220mm.

[0004] The above waterproof backing board production process has the following deficiencies:

[0005] 1. When the cement mortar on the first side solidifies, the stress generated by shrinkage causes the board surface to deform, which is specifically manifested as warping on both sides. When the cement mortar on the second side solidifies, shrinkage stress will also be generated, but the shrinkage stress generated on the first and second sides is not exactly the same, so the shrinkage of the second side cannot offset the stress of the first side when it shrinks, which causes the surface of the waterproof backing board to be uneven, and the uneven surface of the waterproof backing board will directly affect the flatness of the wall after construction;

[0006] 2. The curing time is long. Usually, single-sided steam curing takes 6 hours, and natural curing takes 1 to 7 days, so the time and cycle of double-sided curing is longer;

[0007] 3. Since the maintenance takes a long time, a larger area is required to place the waterproof backing board under maintenance, usually 3000m 2 The daily output of the factory is only 500 m 2 Waterproof backing board.

[0008] At present, the various defects in the production and processing of existing waterproof backing boards are caused by the lack of development of suitable production equipment, especially the rapid drying process of cement mortar has not yet been solved. Summary of the invention

[0009] In view of this, in order to solve the problems of single-sided scraping, long curing time, large floor space, many waste products, and easy warping of finished products in the above process of waterproof backing board, the present invention proposes a fully automated production equipment for waterproof backing board, which can carry out mesh scraping treatment on the first surface of the extruded board, and carry out rapid hot air drying at 50℃~70℃ after the scraping treatment. After drying, the mortar layer on the upper surface of the extruded board is kept at 40℃~50℃, and the semi-finished product is flipped 180° at this temperature, so that the physical positions of the first surface and the second surface of the extruded board are interchanged, and then the second surface is scraped with mesh and rapidly hot air dried at 50℃~70℃ to form the new waterproof backing board of the present invention. The above waterproof backing boards are then cut and stacked for packaging.

[0010] By adopting the fully automated production process of the waterproof backing board of the present invention, the surface slurry layer can be quickly dried online, thus avoiding the problem of warping of the waterproof backing board caused by shrinkage stress caused by natural curing or steam curing; and, since all waterproof backing boards are dried online and cut and stacked, the problems of low plant utilization rate and low finished product output rate caused by natural curing or steam curing are avoided; at the same time, the fully automated production process of the waterproof backing board of the present invention cleverly connects the block extruded boards together for scraping and drying, so that there is only one procedure in the production process of the entire waterproof backing board, that is, waste is only generated during the cutting process, which reduces at least half of the waste of scraps compared with the original production process.

[0011] In order to facilitate a more comprehensive understanding of the continuous production method of the novel waterproof backing board of the present invention, the special terms involved in the present invention are first defined and explained:

[0012] The MD direction is the longitudinal direction, that is, the direction consistent with the running direction of the production line; the CD direction is the transverse direction, that is, the direction perpendicular to the running direction of the production line. The MD direction and the CD direction are located in the same plane and remain perpendicular.

[0013] A fully automated production process for a waterproof backing plate, characterized in that it comprises the following steps:

[0014] Step 1: trim the waterproof backboard so that the overall structure of the waterproof backboard is a rectangle;

[0015] Step 2: Place the trimmed waterproof backboard on the loading platform 1 and sequentially convey it through the first part, the second part, and the third part of the first conveyor belt 3 to the first mesh cloth covering device 21 to cover the upper surface of the trimmed waterproof backboard with mesh cloth, the conveying speed of the loading platform 1 is V1, and the conveying speeds of the first part, the second part, and the third part of the first conveyor belt 3 are V2, V3, and V4 respectively, and V1>V2>V3>V4, so that when multiple trimmed waterproof backboards are sequentially conveyed through the first part, the second part, and the third part of the first conveyor belt 3 to the first mesh cloth covering device 21, adjacent side surfaces are in contact with each other to form a seamless whole, thereby preventing the cement mortar from falling onto the first conveyor belt 3 when spraying cement mortar on the trimmed waterproof backboard, causing malfunctions to the conveyor belt and subsequent transportation;

[0016] Step 3: quantitatively spray the upper surface of the waterproof backboard covered with the mesh cloth through the first cement mortar spraying device 22;

[0017] Step 4: Scrape the sprayed waterproof backboard until the surface of the waterproof backboard is flat;

[0018] Step 5: The scraped waterproof backboard is rapidly dried with hot air at 50°C to 70°C to form a cement mortar layer;

[0019] Step 6: Keep the mortar layer on the upper surface of the waterproof backboard after drying at 40°C-60°C, and flip the semi-finished product 180° at this temperature. Since the surface temperature of the mortar layer is 40°C-60°C at this time, the cement mortar layer is relatively soft and can be flipped, so that the upper and lower surfaces are swapped so that the physical positions of the upper and lower surfaces of the waterproof backboard are interchanged, and when passing through the second conveyor belt 8 to the second mesh cloth covering device 71 in sequence, since the mesh cloth on the upper surface of the waterproof backboard has been bonded to the upper surface of the waterproof backboard by the dried cement mortar, the mesh cloth makes the adjacent sides of the waterproof backboard still in a state of abutting each other after flipping 180°, thereby preventing the cement mortar from falling onto the second conveyor belt 8 when spraying the trimmed waterproof backboard, causing malfunctions to the conveyor belt and subsequent transportation;

[0020] Step 7: The lower surface of the waterproof backboard covered with the mesh cloth is quantitatively sprayed by the second cement mortar spraying device 72, and the waterproof backboard after spraying is scraped flat, and then the scraped waterproof backboard is rapidly hot-air dried at 50° C. to 70° C. to form a cement mortar layer;

[0021] Step 8: Cut and stack the waterproof backboards with the upper and lower surfaces sprayed with dried cement mortar.

[0022] Furthermore, in step 2 or step 6, the mesh cloth is a mesh cloth provided with square or rectangular grooves all over. When spraying cement mortar, the cement mortar will enter the bottom of the mesh cloth through the square or rectangular grooves all over, so that the mesh cloth floats to 1 / 3 of the thickness of the cement mortar. The cement mortar fixes the mesh cloth on the upper surface or lower surface of the waterproof backboard. The square or rectangular grooves all over make it difficult for the cement mortar to overflow.

[0023] Furthermore, the transmission speed of the third portion of the first conveyor belt 3 and the second conveyor belt 8 is 5 m / min to 10 m / min.

[0024] Furthermore, the transmission speed V1 of the loading platform 1 is 6m / min to 12m / min, the transmission speed V2 of the first part of the first conveyor belt 3 is 5m / min to 10m / min, and the transmission speed V3 of the second part of the second conveyor belt 8 is 6m / min to 12m / min.

[0025] Furthermore, the mesh cloth is made of glass fiber and has been alkali-resistant treated.

[0026] Furthermore, the mesh cloth has a thickness of 0.2-0.3 mm.

[0027] Furthermore, the thickness of the cement mortar layer on the upper surface or the lower surface of the waterproof backboard after drying is 1.0-2 mm, and the preferred thickness of the cement mortar layer is 1.2 mm.

[0028] A fully automated production equipment for waterproof backing plates, comprising a loading platform 1, the output end of the loading platform 1 being connected to the first part, the second part, and the third part of a first conveyor belt 3 in sequence, the third part of the first conveyor belt 3 being provided with a first mesh cloth covering device 21, a first cement mortar spraying device 22, a first drying device, and a turning mechanism 5 in sequence, the output end of the first conveyor belt 3 being connected to the input end of the second conveyor belt 8, the second conveyor belt 8 being provided with a second mesh cloth covering device 71, a second cement mortar spraying device 72, a second drying device, a stacking device 11, and a packaging device in sequence.

[0029] Furthermore, the width of the first conveyor belt 3 and the second conveyor belt 8 is 1280 mm, and baffle limit devices with a height of 100 mm are set on both sides. The position of the baffle limit devices is adjustable, which can ensure that the 1220 mm waterproof backboard is consistent with the running direction of the production equipment without deviation. The bottom of the first conveyor belt 3 and the second conveyor belt 8 are respectively provided with a first belt support 4 and a second belt support.

[0030] In some embodiments, in order to save space, the loading platform 1 is horizontally connected to the first conveyor belt 3, and the first conveyor belt 3 and the second conveyor belt 8 can be arranged to be stacked up and down.

[0031] Furthermore, the first cement mortar spraying equipment 22 and the second cement mortar spraying equipment 72 are respectively provided with a first scraper mechanism 23 and a second scraper mechanism 73, and the scrapers of the scraper mechanisms are rigid scrapers, and a spring extrusion device is arranged above them, so that they can scrape the cement mortar layer with a thickness of 1.0-2mm.

[0032] Furthermore, the turnover mechanism 5 is provided with a turnover limiter 6 , which is used to control the dried waterproof backboard containing the mortar layer to enter the second conveyor belt 8 .

[0033] Furthermore, the first drying equipment and the second drying equipment are respectively provided with a first blowing device and a second blowing device, which blow hot air from top to bottom, so that the mortar layer of the waterproof backboard after the scraping treatment is always maintained at 50-70°C, preferably 60°C. The heating device adjusts the temperature in stages, and the temperature forms a parabola. The rapid hot air drying process allows the moisture in the mortar layer to evaporate quickly, eliminating the shrinkage stress of the mortar layer when it is naturally dried, and making the surface of the product smooth.

[0034] Furthermore, the stacking device 11 ensures the accurate size and vertical angle of the finished product by precise positioning of two fixed longitudinal trimming and aligning edge saws 10, two transverse cross-cutting knives for cutting the width of the finished product and one longitudinal saw for cutting the finished product into small pieces. The waterproof backing board is trimmed by two longitudinal trimming saws 10 for cutting off waste materials, and then cut by a transverse saw for cutting the width of the finished product, so that the size of the finished waterproof backing board is 1200mm in length*600mm in width or 1220mm in length*2440mm in width, and is packaged by the packaging machine 12.

[0035] Beneficial effects of the present invention:

[0036] The fully automated production equipment and process of the waterproof backing plate as described above has the following advantages:

[0037] 1. Rapid hot air drying can improve production efficiency, usually 1000m 2 The daily output of the plant is 6000 m 2 Finished product, while avoiding the problem of warping of waterproof backing board caused by shrinkage stress caused by natural curing or steam curing;

[0038] 2.
