Description

Technical Field

[0001] This invention belongs to the technical field of spraying devices, and particularly relates to a spraying device suitable for prefabricated wall panel forming molds. Background Technology

[0002] In the production process of autoclaved precast wall panels, the mold frame is an indispensable piece of equipment. Casting and molding are inseparable from the mold frame. The mold frame used for casting is usually assembled from the frame body and side panels. Before pouring the grout, the four internal surfaces of the mold frame body—the bottom, one inner side, and the front and rear sides—are typically sprayed with oil. This oil spraying process forms an oil film on these four internal surfaces. This oil film significantly reduces the adhesion between the concrete and the mold frame, making it easier to remove the precast wall panels from the mold frame during demolding, thus reducing the possibility of block breakage and mold frame damage.

[0003] However, existing oil spraying devices are prone to uneven oil spraying, which may result in insufficient lubrication in certain areas of the mold frame, thereby affecting the fluidity of the slurry or causing the block surface to be rough during demolding. At the same time, the oil spraying devices are not suitable for spraying oil on mold frames of different sizes, resulting in poor applicability and affecting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing oil spraying devices, which can easily lead to uneven oil spraying, resulting in insufficient lubrication in certain areas of the mold frame, thus affecting the fluidity of the slurry or causing the block surface to be rough during demolding. In addition, the oil spraying devices are not suitable for spraying oil on mold frames of different sizes, resulting in poor applicability and affecting production efficiency. Therefore, this invention proposes an oil spraying device suitable for precast wall panel forming molds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an oil spraying device suitable for precast wall panel forming molds, comprising:

[0006] The mold frame is slidably connected to the linear motor;

[0007] The oil spraying component includes an inner plate, an outer ring plate, and a rotating ball. The rotating ball is rotatably connected between the outer ring plate and the inner plate. A first nozzle body is provided at the bottom of the rotating ball, and an upwardly bent connecting plate is provided at the top. Several connecting plates are connected to a fixed plate.

[0008] The lifting mechanism includes a connecting body, a telescopic cylinder, and a rotating motor. The telescopic cylinder is connected to the connecting body, the rotating motor is connected to the bottom of the telescopic cylinder, and the rotating motor is connected to the fixed plate.

[0009] A retractable rope is provided at the bottom of the connector, and the retractable rope is connected to the outer ring plate.

[0010] As a further description of the above technical solution:

[0011] The first nozzle body is provided with a first screw, the bottom of the rotating ball is provided with a connecting groove, the second screw is screwed into the connecting groove, and the first screw and the second screw are fixed by screws.

[0012] As a further description of the above technical solution:

[0013] The first screw and the second screw are arranged perpendicularly.

[0014] As a further description of the above technical solution:

[0015] The bottom of the inner plate is provided with several second nozzles.

[0016] As a further description of the above technical solution:

[0017] The connector is attached to the hanging rod.

[0018] As a further description of the above technical solution:

[0019] The retractable rope is a spiral rope.

[0020] As a further description of the above technical solution:

[0021] The mold frame includes a frame and a stripping template, the stripping template being detachably connected to the frame.

[0022] As a further description of the above technical solution:

[0023] The spraying component is located directly above the mold frame.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, a lifting mechanism is connected to the spraying component, and a spiral rope is used in conjunction to form a lever structure. This allows the first nozzle to adjust its angle along the rotation of the sphere, thus satisfying the requirement of spraying oil onto the four sides of the mold frame. By setting several second nozzles at the bottom of the inner plate in the spraying component, oil spraying is achieved at the bottom of the mold frame. This structure can be modified by changing the spiral rope of different lengths according to the size of the mold frame, allowing the first nozzle to rotate at an angle along the sphere. This, in conjunction with the lifting mechanism, enables uniform oil spraying onto the upper and lower parts of the mold frame, improving the uniformity of oil spraying on the inner wall of the mold frame, and also has strong applicability.

[0026] 2. In this invention, when faced with mold frames of different sizes, the spray area and stroke of the oil spray are controlled by changing the length of the first screw and the second screw, so that the oil spraying part can be applied to mold frames of different sizes, and has strong applicability.

[0027] 3. In this invention, a rotating motor is installed at the bottom of the telescopic cylinder, so that while the oil spraying part is moving downward, the angle is adjusted and the first nozzle is rotated, so as to avoid dead corners in the mold frame that are not sprayed with oil, which would affect the effect.

[0041] Please see Figures 1-4 The present invention provides a technical solution: an oil spraying device suitable for precast wall panel forming molds, comprising:

[0042] Module 1, which is slidably connected to linear motor 2;

[0043] The oil spraying component 3 includes an inner plate 31, an outer ring plate 32, and a rotating ball 33. The rotating ball 33 is rotatably connected between the outer ring plate 32 and the inner plate 31. A first nozzle body 4 is provided at the bottom of the rotating ball 33, and an upwardly bent connecting plate 5 is provided at the top. Several connecting plates 5 are connected to a fixed plate 6.

[0044] The lifting mechanism 7 includes a connecting body 71, a telescopic cylinder 72, and a rotating motor 73. The telescopic cylinder 72 is connected to the connecting body 71, the rotating motor 73 is connected to the bottom of the telescopic cylinder 72, and the rotating motor 73 is connected to the fixed plate 6.

[0045] A retractable rope 8 is provided at the bottom of the connector 71, and the retractable rope 8 is connected to the outer ring plate 32.

[0046] The first nozzle body 4 is provided with a first screw 9, the bottom of the rotating ball 33 is provided with a connecting groove 10, and the second screw 11 is screwed into the connecting groove 10. The first screw 9 and the second screw 11 are fixed by screws.

[0047] The first screw 9 and the second screw 11 are arranged perpendicularly. This allows the lengths of the first and second screws to be changed according to different mold frame sizes, making the nozzle suitable for different mold frame sizes when spraying around the mold frame.

[0048] The bottom of the inner plate 31 is provided with several second nozzles 12. The bottom of the mold frame is sprayed with oil.

[0049] The connecting body 71 is connected to the hanging rod 13 to ensure the stability of the lifting mechanism during descent.

[0050] The retractable rope 8 is a spiral rope. When the telescopic cylinder drives the rotating motor to move downward, the spiral rope can also be stretched. During the stretching process, in conjunction with the ball, it ensures that the first nozzle rotates at a certain angle, thereby ensuring that the angle of the first nozzle changes during the downward movement. It can move up and down to spray oil on the side wall, improving the oil spraying effect.

[0051] The mold frame 1 includes a frame 1a and a stripping template 1b, wherein the stripping template 1b is detachably connected to the frame 1a. This facilitates the disassembly of the precast wall panels after the paint is sprayed and the concrete is poured.

[0052] The spraying component 3 is located directly above the mold frame 1. This ensures that the spraying component sprays oil onto the inner wall of the mold frame during its downward movement, guaranteeing uniform oil spraying.

[0053] Working Principle: A lifting mechanism connected to the spraying component, along with a spiral rope, forms a lever structure. This allows the first nozzle to adjust its angle along the rotation of the sphere, ensuring even spraying of oil onto the side walls of the mold frame. Several second nozzles are located at the bottom of the inner plate of the spraying component, enabling oil spraying onto the bottom of the mold frame. This structure allows for the replacement of spiral ropes of varying lengths according to the mold frame size, enabling the first nozzle to rotate along the sphere. This, combined with the lifting mechanism, ensures uniform oil spraying onto the upper and lower parts of the mold frame, improving the uniformity of oil spraying on the inner walls. It is also highly adaptable; by adjusting the lengths of the first and second screws, the spray area and stroke can be controlled for mold frames of different sizes, making the spraying component suitable for various mold frame dimensions.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
