Description

Technical Field

[0001] This application relates to the field of rock wool production equipment, and in particular to a lifting rock wool spraying device. Background Technology

[0002] The descriptions in this section provide background information related to this disclosure only and do not constitute prior art. Rock wool fiber products use basalt, dolomite, slag, etc. as the main raw materials. They are heated by coke or electrodes and melted at a high temperature of over 1450℃. Then, they are centrifuged into fibers at high speed using a four-roller centrifuge. At the same time, a certain amount of binder, dust-proofing oil, and water-repellent agent are sprayed in. The fibers are then collected by a cotton collector and processed by a pendulum method. After three-dimensional cotton laying, the fibers are pleated, pressed, cured, and cut to form rock wool products of different specifications and uses.

[0003] Rock wool requires adhesive spraying during production. In related technologies, the spray nozzles in the adhesive spraying equipment are fixed at a constant height. However, since the height of the rock wool on the production line varies from batch to batch, if the nozzle is too close to the rock wool, the spray area is too small and cannot cover it completely. If the nozzle is too close, the spray area is too large, resulting in a thinner adhesive and poor bonding. Furthermore, the nozzle moves back and forth under the drive of a linear module, creating an S-shaped adhesive trajectory on the rock wool. This S-shaped trajectory cannot fully cover the rock wool, leading to poor adhesion. Summary of the Invention

[0004] In view of this, this application provides a lifting rock wool spraying device, which can improve the spraying effect.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A lifting rock wool spraying device is characterized by comprising a glue storage tank, a conveying platform for forward conveying of rock wool, a lifting frame mounted on the conveying platform, and a lifting mechanism for driving the lifting frame to move up and down. The lifting frame has at least one horizontal bar extending in the left-right direction, and two or more spray nozzles spaced apart in the left-right direction are fixedly installed at the bottom of the horizontal bar. The glue storage tank supplies glue to the spray nozzles through pipelines.

[0007] The aforementioned lifting-type rock wool adhesive spraying device, through a lifting mechanism, can drive the lifting frame to move up and down, adjusting the relative distance between the spray nozzles and the rock slab to ensure the nozzles are at the optimal height, thereby improving the adhesive spraying effect. Furthermore, the multiple spray nozzles are fixedly mounted on the crossbar, avoiding an S-shaped curve, thus ensuring the adhesive is evenly sprayed onto the product surface.

[0008] The spray nozzle is an atomizing spray nozzle, and the conveyor can be a roller conveyor, chain conveyor, or belt conveyor, etc.

[0009] In some embodiments, two lifting mechanisms are provided, distributed on the left and right sides of the conveyor platform. Each lifting mechanism includes a screw jack fixedly connected to the conveyor platform and a drive motor for driving the screw jack to rotate. The nut of the screw jack is fixedly connected to the conveyor platform. This lifting mechanism offers high adjustment accuracy, good stability, and strong load-bearing capacity.

[0010] In some embodiments, the number of crossbars is two, spaced apart, and each crossbar has a glue nozzle at its bottom. The lifting rock wool glue spraying device also includes two control valves that control the opening and closing of the glue nozzles under the two crossbars respectively. Because the production speed of products online varies, insufficient glue application during the spraying process can easily lead to poor bonding and directly affect product quality. By setting two rows of glue nozzles, the glue amount can be replenished during the spraying process by opening and closing the second row of nozzles, achieving a better bonding effect.

[0011] In some embodiments, enclosure assemblies are installed on the left and right sides of the conveyor table. Each enclosure assembly includes a base and a baffle. The base is fixedly mounted on the conveyor table and has a sleeve. A telescopic rod, movable and insertable into the sleeve, is fixedly provided on the back of the baffle, allowing the baffle to move and adjust relative to the base in the left-right direction. A push rod is also threaded onto the base, with its end extending into the sleeve and pressing against the telescopic rod. The baffle can intercept adhesive, preventing it from spraying onto the outside of the conveyor table. Furthermore, the baffle is adjustable in the left-right direction, offering good applicability and flexibility.

[0012] In some embodiments, the inner side of the baffle is also covered with a peelable film. Adhesive may splatter onto the peelable film, which can be peeled off and replaced after a certain period of use.

[0013] In some embodiments, the glue storage tank is provided with a high-pressure air inlet, a pressure gauge and a pressure relief valve. The high-pressure air inlet is connected to a high-pressure air supply device to supply high-pressure gas into the glue storage tank.

[0014] In fact, rock wool uses composite adhesive. Composite adhesive has poor flowability. By pressurizing the adhesive storage tank, the adhesive can enter the spray nozzle better and be atomized, so that the adhesive can be evenly sprayed onto the product surface.

[0015] In some embodiments, the upper part of the glue storage tank is also provided with a feed inlet, and a sealing cap is detachably provided on the feed inlet. The lower part of the glue storage tank is also provided with a drain outlet, and the glue storage tank is also provided with a vertically extending observation port.

[0016] In related technologies, in order to avoid insufficient raw materials during equipment use, it is necessary to add raw materials to the equipment at any time, which increases the workload. This application uses a storage tank to store a large amount of raw materials inside. During equipment operation, the content of raw materials inside can be observed through the observation port, reducing the step of manual addition and saving labor costs.

[0017] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0018] This application discloses a lifting-type rock wool adhesive spraying device. The lifting mechanism drives the lifting frame to move up and down, adjusting the relative distance between the spray nozzles and the rock slab to achieve the optimal height and distance for better adhesive application. Furthermore, the multiple spray nozzles are fixedly mounted on a horizontal bar, avoiding an S-shaped curve, thus ensuring even application of the adhesive to the product surface.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0026] See Figures 1 to 5This application provides a lifting rock wool spraying device, including a glue storage tank 1, a conveying platform 2 for conveying rock wool forward, a lifting frame 3 set on the conveying platform 2, and a lifting mechanism 4 for driving the lifting frame 3 to move up and down. The lifting frame 3 has at least one horizontal bar 31 extending in the left and right direction. Two or more spray nozzles 5 are fixedly installed at the bottom of the horizontal bar 31 and are spaced apart in the left and right direction. The glue storage tank 1 provides glue to the spray nozzles 5 through pipelines.

[0027] This lifting-type rock wool adhesive spraying device uses a lifting mechanism 4 to drive the lifting frame 3 to move up and down, adjusting the relative distance between the spray nozzles 5 and the rock slab to ensure the nozzles 5 are at the optimal height, thereby improving the adhesive spraying effect. Furthermore, the multiple spray nozzles 5 are fixedly mounted on the crossbar 31, avoiding an S-shaped curve, thus ensuring the adhesive is evenly sprayed onto the product surface.

[0028] The spray nozzle 5 is an atomizing spray nozzle, and the conveyor table 2 can be a roller conveyor table 2, a chain conveyor table 2, or a belt conveyor, etc. The number of spray nozzles 5 can be increased or decreased as needed, preferably 4-6.

[0029] There are two lifting mechanisms 4, distributed on the left and right sides of the conveyor platform 2. Each lifting mechanism 4 includes a screw jack 41 fixedly connected to the conveyor platform 2 and a drive motor 42 for driving the screw jack 41 to rotate. The nut of the screw jack 41 is fixedly connected to the conveyor platform 2. This lifting mechanism 4 has high adjustment accuracy, good stability, and strong load-bearing capacity.

[0030] The device consists of two horizontal bars 31 spaced apart, each with a glue nozzle 5 at its bottom. The lifting rock wool glue spraying device also includes two control valves that control the opening and closing of the glue nozzles 5 under the two horizontal bars 31. Because the production speed varies online, insufficient glue application during spraying can lead to poor bonding and directly affect product quality. By using two rows of glue nozzles 5, the second row can be opened and closed during spraying to replenish the glue, achieving a better bonding effect.

[0031] Enclosure assemblies 6 are installed on the left and right sides of the conveyor table 2, respectively. Each enclosure assembly 6 includes a base 61 and a baffle 62. The base 61 is fixedly installed on the conveyor table 2 and has a sleeve 611. A telescopic rod 63, which can be movably inserted into the sleeve 611, is fixedly installed on the back of the baffle 62, allowing the baffle 62 to move and adjust relative to the base 61 in the left and right directions. A push rod 64 is also threaded onto the base 61, with its end extending into the sleeve 611 and pressing against the telescopic rod 63. The baffle 62 can intercept adhesive, preventing it from spraying onto the outside of the conveyor table 2. Furthermore, the baffle 62 is adjustable in the left and right directions, offering good applicability and flexibility.

[0032] The inside of the baffle 62 is also covered with a peelable film. Glue may splatter onto the peelable film, which can be peeled off and replaced after a certain period of use.

[0033] The storage tank 1 is equipped with a high-pressure air inlet 11, a pressure gauge 12 and a pressure relief valve. The high-pressure air inlet 11 is connected to a high-pressure air supply device to supply high-pressure gas to the storage tank 1.

[0034] In fact, rock wool uses composite adhesive. Composite adhesive has poor flowability. By pressurizing the adhesive storage tank 1, the adhesive can enter the spray nozzle 5 better and be atomized, so that the adhesive can be evenly sprayed onto the product surface.

[0035] The upper part of the glue storage tank 1 is also provided with a feed inlet 13, and a sealing cover 14 is detachably provided on the feed inlet 13. The lower part of the glue storage tank 1 is also provided with a drain outlet 15, and the glue storage tank 1 is also provided with a vertically extending observation port 16.

[0036] In related technologies, in order to avoid insufficient raw materials during equipment use, it is necessary to add raw materials to the equipment at any time, which would increase the workload. This application uses a storage tank 1 to store a large amount of raw materials inside. During equipment operation, the content of raw materials inside can be observed through the observation port 16, reducing the steps of manual addition and saving labor costs.

[0037] The following is a brief description of the working process and usage method of a lifting rock wool spraying device according to the above embodiments:

[0038] Based on the width and thickness of the rock wool, the lifting mechanism 4 moves the spray nozzles 5 to a suitable height and stops, while the baffle 62 is adjusted to the appropriate left and right positions. The rock wool moves from the previous process to the conveyor table 2, and multiple spray nozzles 5 atomize the adhesive and spray it downwards, evenly spraying the adhesive onto the product surface. If the speed of the previous process is increased, the second row of spray nozzles can be opened for additional adhesive application to achieve a better bonding effect.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
