Description

Technical Field

[0001] The invention belongs to the technical field of autoclaved aerated concrete product production, and in particular relates to a cleaning and oiling device for a mold used in the production of autoclaved aerated concrete products. Background Art

[0002] In the production process of autoclaved aerated concrete products, before the blank casting process, it is necessary to clean the blank residue remaining in the mold after the previous mold frame blank casting production, and oil the inner surface of the mold to prevent the fresh mortar from being contaminated and avoid adhesion between the blank and the mold frame during the production process, thereby affecting the quality of the autoclaved aerated concrete products.

[0003] In the actual production process of autoclaved aerated concrete products, the mold used for casting the green body is usually composed of a bottom plate, two end plates and two side plates. Among them, the two end plates and the two side plates are hinged to the bottom plate. When pouring, the two side plates and the two end plates are erected to form a mold frame together with the mold bottom plate. When cleaning and oiling are required, the mold bottom plate, the two side plates and the two end plates are pre-expanded into a plane, and then the expanded mold is passed through the cleaning equipment and the oiling equipment in sequence through the mold conveyor line. The existing mold cleaning equipment usually uses a roller brush to rotate for cleaning. If a large volume of green body residue is encountered, it needs to be pre-processed manually, otherwise the inner surface of the mold cannot be thoroughly cleaned. Because of the need for manual pre-processing, the labor intensity is increased and the production efficiency is low. The existing mold oiling equipment uses an oiling roller to directly apply oil on the expanded mold surface by rotating and rolling, which consumes a lot of oil and causes unnecessary waste. Furthermore, in the prior art, the cleaning equipment and the oiling equipment are separately provided, which occupies a large space and has a high equipment cost, which indirectly causes an increase in the production cost of the autoclaved aerated concrete products. Summary of the invention

[0004] The purpose of the present invention is to provide a cleaning and oiling device for a mold used in the production of autoclaved aerated concrete products.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a cleaning and oiling device for molds used in the production of autoclaved aerated concrete products, including a frame that can be set across the mold conveyor line, the direction in which the frame is used to cross the conveyor line is defined as the length direction of the frame, and a scraper device for cleaning large pieces of green body residue on the mold, a rotating cleaning device for cleaning remaining residues, and an oiling device for oiling the mold are sequentially arranged on the frame along the width direction perpendicular to the length.

[0010] Furthermore, the scraper support frame includes a support shaft and two scraper support plates fixed at both ends of the support shaft, and the scraper shaft in the scraper assembly can be rotatably supported between the two scraper support plates.

[0011] Furthermore, the scraper mounting frame is provided with a mounting shaft, on which a support ear plate is fixed and which is installed in cooperation with the support shaft. The mounting shaft is inclined in the horizontal plane with respect to the length direction of the frame, so that the cleaning force direction of the scraper assembly forms a certain angle with the straight line of the mold conveying direction in the horizontal plane.

[0012] Furthermore, the scraper mounting frame is provided with a mounting shaft, on which a supporting ear plate is fixed and which is installed in cooperation with the supporting shaft. The mounting shaft is arranged in parallel with the length direction of the frame in a horizontal plane. By setting the two supporting ear plates supporting the same supporting shaft to different sizes, the cleaning force direction of the scraper assembly forms a certain angle with the straight line where the mold conveying direction is located in the horizontal plane.

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the invention in any way.

[0031] like Figure 1-3 As shown, a cleaning and oiling device for molds used in the production of autoclaved aerated concrete products includes a frame 3 that can be set across the mold conveyor line, and the direction in which the frame 3 is used to cross the conveyor line is defined as the length direction of the frame. On the frame 3, along the width direction perpendicular to the length, a scraper device 4 for cleaning large pieces of green body residue on the mold 1 and a rotating cleaning device 5 for cleaning remaining residues are arranged in sequence, and an oiling device 6 for oiling the mold 1 is also provided.

[0032] In this embodiment, the scraper device 4 includes a scraper assembly 403, a scraper support frame 402 and a scraper mounting frame 401. The scraper assembly 403 can be rotatably supported on the scraper support frame 402, the scraper support frame 402 can be rotatably mounted on the scraper mounting frame 401, the scraper mounting frame 401 is fixedly connected to the frame 3, and a scraper adjustment mechanism 404 for adjusting the position of the scraper assembly 403 is provided between the scraper mounting frame 1 and the scraper support frame 402.

[0033] In this embodiment, the scraper assembly is preferably three independent sets, namely, the mold bottom plate scraper assembly located in the middle and the mold side plate scraper assembly located on both sides. The mold bottom plate scraper assembly and the mold side plate scraper assembly are separately arranged to facilitate later maintenance and replacement, which can save production costs. The scraper assembly can also be a set, which is long enough to clean the mold bottom plate and two mold side plates at the same time.

[0034] like Figure 5 , Figure 6 As shown, in this embodiment, the scraper adjustment mechanism 404 includes an air spring 404a for driving the scraper support frame 402 to move and an adjustment spring assembly for returning the scraper support frame 402; one end of the air spring 404a is connected to a movable mounting plate 402b arranged on the scraper support frame 402, and the other end is connected to a fixed mounting plate 401e arranged on the scraper mounting frame 401; the adjustment spring assembly includes an adjustment spring 404c and a spring guide rod 404b, the spring guide rod 404b passes through the movable mounting plate 402b and the fixed mounting plate 401e, the adjustment spring 404c is installed on one end of the spring guide rod 404b extending out of the fixed mounting plate 401e, and limiting members are respectively arranged at both ends of the spring guide rod 404b; the adjustment spring assembly consists of two sets, which are respectively arranged on both sides of the air spring 404a. In order to protect the air spring 404a, an air spring limit protection rod 404d is provided between the movable mounting plate 402b and the fixed mounting plate 401e at a position above the air spring 404a.

[0035] In this embodiment, the scraper assembly 403 includes a scraper shaft 403a and a scraper 403b fixed on the scraper shaft 403a, and the scraper assembly 403 is supported on the scraper support frame 402 through the scraper shaft 403a. The scraper support frame 402 includes a support shaft 402c and two scraper support plates 402a fixed at both ends of the support shaft 402c, and the scraper shaft 403a in the scraper assembly can be rotatably supported between the two scraper support plates 402a. Specifically, the scraper shaft 403a can be supported on the scraper support plate 402a through a bearing seat, and the scraper shaft 403a is arranged between the two scraper support plates 402a through the bearing seats at both ends.

[0036] In order to make the cleaning force direction of the scraper assembly be set at a certain angle to the straight line of the mold conveying direction, so as to reduce the cleaning resistance and facilitate the timely discharge of large pieces of green body residue from the side of the mold side plate, the scraper mounting frame preferably adopts the following structure:

[0037] like Figure 4 As shown, the first implementation method:

[0038] The scraper mounting frame includes a mounting shaft 401a, on which a support ear plate 401d is fixed to cooperate with the support shaft 402c, and the mounting shaft 401a is inclined in the horizontal plane with the length direction of the frame, so that the cleaning force direction of the scraper assembly forms a certain angle with the straight line where the mold conveying direction is located in the horizontal plane. In this concept, the specific scheme can be: the scraper mounting frame includes a long tube used as a mounting shaft, and a connecting rod 401b vertically connected to one end of the long tube, one end of the connecting rod 401b is connected to the mounting shaft 401a, and the other end is connected to the frame 3, the other end of the mounting shaft 401a is also fixed to the frame 1, and the mounting shaft 401a and the connecting rod 401b are respectively fixedly connected to the frame 3 through their respective mounting connecting plates 401c.

[0039] The connecting rod 401b may also be a pipe fitting. In practical applications, the mounting shaft 401a and the connecting rod 401b may also be solid shafts. Preferably, a pipe fitting can reduce weight.

[0040] In this concept, except for the installation axis 401a of the scraper mounting frame being inclined in the length direction of the frame, the rest of the structure can be transformed in many ways, which will not be described in detail here.

[0041] The second implementation method:

[0042] In this embodiment, the scraper mounting frame 401 includes a mounting shaft 401a, on which a support ear plate 401d is fixed to cooperate with the support shaft 402c. The mounting shaft 401a is arranged in parallel with the length direction of the frame in a horizontal plane. By setting the two support ear plates 401d supporting the same support shaft 402c to different sizes, the cleaning force direction of the scraper assembly forms a certain angle with the straight line where the mold conveying direction is located in the horizontal plane.

[0043] In this structure, the dimensions of the two supporting ear plates 401d can be made one longer and one shorter in the horizontal direction, so that the positions of the support shaft mounting holes set thereon are one close to the mounting shaft 401a and one far away from the mounting shaft 401a, and finally the support shaft 402c is set at an angle with the mounting shaft 401a, so that the cleaning force direction of the scraper assembly is set at a certain angle to the straight line where the mold conveying direction is located. In this embodiment, the scraper support frame 402 can be set with an adjustable floating connection mechanism between the frame 3 to meet the cleaning operation under different working conditions and avoid unnecessary losses.

[0044] The rotary cleaning device 5 can adopt the existing technology.

[0045] like Figure 3 , Figure 7 As shown, in this embodiment, the rotary cleaning device 5 includes a brush roller 501 with a brush roller, a driving motor 503 for driving the brush roller to rotate, and a brush roller shield 502 for protecting the brush roller. Both ends of the brush roller are mounted on the frame 3 through bearing seats mounted on the extension shaft, and the center line of the brush roller is arranged parallel to the length direction of the frame. The driving motor 503 and the brush roller shield 502 are both fixedly mounted on the frame 3, and the output shaft of the driving motor 503 is drivingly connected to the extension shaft at one end of the brush roller. The lower opening of the brush roller shield 502 allows the brush roller to extend for operation.

[0046] The oiling device 6 is arranged on the frame 3 or on an independent oiling frame.

[0047] like Figure 8-10 As shown, the oiling device 6 includes an oiling nozzle 603 for spraying oil to the mold, an air supply pipeline for supplying air to the oiling nozzle 603, and an oil supply pipeline for supplying oil to the oiling nozzle 603. An oiling felt 605 for evenly coating the oil sprayed on the mold by the oiling nozzle is arranged behind the oiling nozzle 603 on the frame 3. For an oiling device provided with an independent oiling frame, the oiling felt 605 is arranged on the oiling frame.

[0048] In this embodiment, the oil pipeline includes an oil circuit bracket 601 and a connecting oil pipe 604 arranged on the frame 3. The oil circuit bracket 601 is a profile with an oil circuit channel. A plurality of oil outlets are arranged on the oil circuit bracket 601. Each oil outlet is connected to the injector oil circuit channel 603a in the injector 603 through a connecting oil pipe 604.

[0049] The gas pipeline includes an air path support 602 and a connecting air pipe 607 arranged on the oil path support 601. The air path support 602 is a profile with an air path channel. A plurality of air outlets are arranged on the air path support 602. Each air outlet is connected to the injector air path channel 603b in the injector 603 through a connecting air pipe 607.

[0050] The oil spray nozzle 603 is arranged between the oil circuit support 601 and the gas circuit support 602, and is fixedly mounted on the oil circuit support 601. The oil spray port 603c provided on the oil spray nozzle 603 faces the surface of the mold 1 to be oiled.

[0051] The oil injection shield 606 comprises an upper shield 606a and a lower shield 606b, and both shields are hingedly mounted on the frame 3.

[0052] In this embodiment, the fuel injector is an independent device with a fuel injector oil passage 603a, a fuel injector gas passage 603b and a fuel injection port 603c provided on a fuel injector 603, and then several independent fuel injectors are connected in parallel to form a fuel injection assembly.

[0053] In another embodiment, the fuel injector 603 is a single part that includes several fuel injection groups, each of which includes a fuel injector oil channel 603a, a fuel injector air channel 603b and a fuel injection port 603c. The fuel injector oil channel 603a, the fuel injector air channel 603b and the fuel injection port 603c in each fuel injection group are independently arranged.

[0054] The workflow of the present invention is as follows:

[0055] When the mold 1 to be cleaned and oiled is transported to the cleaning and oiling station via the conveyor line 2, the front end of the mold 1 pushes the scraper 403b on the scraper assembly 403 in the scraper device 4 to rotate, so that a certain scraper 403b in the scraper assembly 403 contacts the upper surface of the unfolded mold, and then the air spring 404a in the scraper adjustment mechanism 404 is inflated, so that the scraper 403b in contact with the mold presses the upper surface of the mold, and as the mold 1 moves forward, the blank residue on the upper surface of the mold is scraped off; then the mold 1 is transported to the bottom of the rotary cleaning device 5, and after passing through the rotary cleaning device 5, the brush roller 501 rotates under the drive of the drive motor 503, and the roller brush cleans the upper surface of the mold, and then the mold 1 continues to be transported by the conveyor line 2 to the oiling station, The oil used for oiling enters the oil nozzle oil path channel 603a in the oil nozzle 603 through the oil path bracket 601 and the connecting oil pipe 604, and then the compressed air enters the oil nozzle air path channel 603b in the oil nozzle 603 through the air path bracket 602 and the connecting air pipe 607. Under the action of the compressed air, the oil is sprayed onto the upper surface of the mold 1 through the oil injection port 603c on the oil nozzle 603, and then the sprayed oil is evenly spread through the oiling felt 605, finally completing the cleaning and oiling process of the mold.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Those skilled in the art should understand that the specific implementation modes of the present invention may be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the claims of the present invention.
