Description

Technical Field

[0001] This utility model relates to the field of waterproof backing board spraying technology, and in particular to a waterproof coating spraying device for waterproof backing boards. Background Technology

[0002] Currently, the spraying of the waterproof coating is a crucial step in the manufacturing process of waterproof backing panels. Waterproof backing panels are widely used in construction, transportation, water conservancy, and other fields, and their waterproof performance directly affects the product's quality and service life. However, there are some significant problems and challenges in the existing waterproof coating spraying process.

[0003] Traditional waterproof coating spraying equipment often lacks effective measures to prevent paint splatter. During the spraying process, paint is easily splashed everywhere, which not only wastes paint but may also pollute the surrounding environment and increase the cleaning workload of operators. In addition, paint splatter may also damage the spraying equipment itself and shorten its service life.

[0004] To address these issues, we propose a waterproof coating spraying device for waterproof backing boards, which provides effective protection against paint splashing and enables uniform and comprehensive spraying of the waterproof backing boards. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a waterproof coating spraying device for waterproof backing boards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waterproof coating spraying device for a waterproof backing board includes: an operation box, inside which are two sets of clamps, an extrusion assembly installed on one side of one set of clamps, a motor fixedly installed on the side wall of the operation box, a transmission component fixedly installed on the drive end of the motor, one end of the transmission shaft being connected to the other set of clamps and a connecting frame respectively through a dual transmission mechanism, a protective cover fixedly installed on the top of the connecting frame, the protective cover being distributed on the top of the operation box, and a purification assembly installed in the middle of the protective cover;

[0008] A spraying device used to spray waterproof backing boards.

[0009] Preferably, the dual transmission mechanism includes a driven gear meshing with the transmission component, a rotating drum fixedly installed in the middle of the driven gear, a transmission shaft rotatably installed in the inner cavity of the rotating drum via a bearing, a first chuck fixedly installed on one side of the rotating drum, a second chuck unidirectionally meshing with the first chuck, and a first rotating shaft driven and installed on the other side of the rotating drum via a transmission belt assembly. One end of the first rotating shaft is fixedly installed with a connection, and the other end of the first rotating shaft is rotatably installed with the side wall of the operating box. The side walls of the first chuck and the second chuck are both provided with unidirectional teeth, which can synchronously drive the protective cover and the clamp to rotate.

[0010] Preferably, a rectangular groove is provided in the middle of the second chuck, and a rectangular shaft is movably installed in the rectangular groove. One end of the rectangular shaft is fixedly installed to the side wall of the clamp on one side. A spring is sleeved on the outer wall of the rectangular shaft. The second chuck and the side wall of the clamp are fixedly installed on both sides of the spring, respectively, so as to support the second chuck.

[0011] Preferably, the control box is a box without a top cover, and the front side wall has an operation groove to facilitate the operator to spray the waterproof backing board.

[0012] Preferably, the extrusion assembly includes a screw hole in the middle of the other side of the operating box, a screw rod screwed in the screw hole, and an extrusion plate rotatably installed at the other end of the screw rod. The middle of the other side of the extrusion plate is rotatably connected to the corresponding clamping seat through a second rotating shaft. Limiting holes are provided on the upper and lower sides of the screw hole and are provided on the operating box 1. Limiting rods are movably installed in both sets of limiting holes. One end of each set of limiting rods is fixedly installed to the side wall of the extrusion plate, which can position the waterproof backing plate between the two sets of clamping seats.

[0013] Preferably, the purification component includes a through hole in the middle of the top of the protective cover, a negative pressure pipe connected and installed outside the through hole, and an exhaust fan installed inside the through hole. The other end of the negative pressure pipe is connected and installed in the purification box, which can absorb the gas inside the operating box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses a drive motor to rotate a transmission component. Since the transmission component meshes with a driven gear on the outside of the rotating drum, and the rotating drum is connected to a first rotating shaft fixedly mounted at the bottom of the connecting frame via a transmission belt assembly, the protective cover on top of the operating box can rotate in any direction, effectively preventing paint splattering. Simultaneously, when the operator reverses the drive motor to rotate the transmission component, the driven gear meshing with the transmission component synchronously drives the first chuck to rotate in the opposite direction. As the first chuck rotates in the opposite direction, the teeth on the first chuck mesh with the teeth on the second chuck, synchronously driving the internal rectangular shaft of the second chuck to rotate. This allows the waterproof backing plates inside the two sets of clamps to rotate in one direction, facilitating comprehensive spraying of the waterproof backing plate surface by the operator through the operating slot.

[0016] A screw is screwed into the screw hole, and an extrusion plate is rotatably installed at the other end of the screw. When the operator places the waterproof backing board to be sprayed between the two sets of clamps, the screw in the screw hole can be continuously tightened to extrude the extrusion plate rotatably installed at one end of the screw, ensuring that both sides of the waterproof backing board are tightly attached to the side walls of the two sets of clamps. This ensures that the waterproof backing board is firmly fixed between the two sets of clamps, making it convenient for the operator to spray the surface of the waterproof backing board.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3A waterproof coating spraying device for a waterproof backing board includes: an operation box 1, inside which are arranged two sets of clamps 3. One set of clamps 3 has a pressing component on one side for driving the clamps 3 to move horizontally within the operation box 1. The other set of clamps 3 has a motor 11 mounted on the outer wall of the operation box 1 on one side. The motor 11 is a rotary drive motor. A transmission component 12 is fixedly mounted on the driving end of the motor 11. One side of the transmission component 12 is connected to the corresponding clamp 3 and a connecting frame 13 through a double transmission mechanism. A protective cover 14 is fixedly mounted on the top of the connecting frame 13. The protective cover 14 is located on the top of the operation box 1. A purification unit is installed in the middle of the operation box 1. The transmission component 12 is a gear. The dual transmission mechanism includes a driven gear 2 meshing with the transmission component 12, a rotating drum 21 fixedly mounted in the middle of the driven gear 2, a transmission shaft 22 rotatably mounted in the inner cavity of the rotating drum 21 via bearings, a first chuck 23 fixedly mounted on one side of the rotating drum 21, a second chuck 24 unidirectionally meshing with the first chuck 23, and a first rotating shaft mounted on the other side of the rotating drum 21 via a transmission belt assembly 25 (including a transmission belt and two transmission pulleys respectively mounted on the first rotating shaft and the rotating drum 21, and driven by the transmission belt to realize the transmission between the rotating drum 21 and the first rotating shaft). One end of the first rotating shaft is fixed to the connecting frame 13. The first rotating shaft is rotatably mounted to the side wall of the operating box 1 via a bearing. Both the first chuck 23 and the second chuck 24 have unidirectional teeth on their side walls, allowing them to synchronously rotate the protective cover 14 and the clamping seat 3. The operating box 1 has a box-like design without a top cover, and an operating groove is provided on the front side wall to facilitate the operator's spraying of the waterproof backing plate clamped between the two sets of clamping seats 3. The drive motor 11 drives the transmission component 12 to rotate. Since the transmission component 12 meshes with the driven gear 2 on the outside of the rotating drum 21, the rotating drum 21 is connected to the first rotating shaft fixedly mounted at the bottom of the connecting frame 13 via the transmission belt assembly 25. This allows the protective cover 14 on the top of the operating box 1 to rotate in any direction, effectively preventing... To prevent paint splattering during spraying, when the operator reverses the drive motor 11 to rotate the transmission component 12, the driven gear 2 meshing with the transmission component 12 will synchronously drive the first chuck 23 to rotate in the opposite direction. As the first chuck 23 rotates in the opposite direction, the teeth on the first chuck 23 will mesh with the teeth on the second chuck 24, synchronously driving the internal rectangular shaft 26 of the second chuck 24 to rotate. This allows the waterproof backing plates inside the two sets of clamps 3 to rotate in one direction, facilitating the operator to spray the surface of the waterproof backing plate comprehensively through the operating slot. The forward and reverse drive of the motor 11 is a known technology, that is, a motor capable of forward and reverse drive is used, and its forward and reverse rotation is controlled by a motor forward and reverse control module, which will not be elaborated on here.

[0023] In this embodiment, the spraying device 36 uses a spray gun, which is connected to a paint container located at the bottom of the control box 1 via a pipeline. The operator holds the gun by hand. How to control the spray gun to spray paint from the paint container is a well-known technology and will not be described in detail here.

[0024] Furthermore, the extrusion assembly includes a screw hole in the middle of the other side of the operating box 1, a screw 31 screwed in the screw hole, and an extrusion plate 32 rotatably installed at the other end of the screw 31. The middle of the other side of the extrusion plate 32 is rotatably connected to the corresponding clamp 3 via a second rotating shaft. Limiting holes are provided on the upper and lower sides of the screw hole on the operating box 1. Limiting rods 33 are movably installed in both limiting holes. One end of each of the two sets of limiting rods 33 is fixedly installed to the side wall of the extrusion plate 32. During spraying, the waterproof backing board can be positioned between the two sets of clamps 3. After the operator places the waterproof backing board to be sprayed between the two sets of clamps 3, the screw 31 in the screw hole can be continuously tightened to push the extrusion plate 32 rotatably installed at one end of the screw 31, ensuring that the two sides of the waterproof backing board are tightly attached to the side walls of the two sets of clamps 3, so that the waterproof backing board is fixed between the two sets of clamps 3, making it convenient for the operator to spray the surface of the waterproof backing board.

[0025] Furthermore, the purification component includes a through hole in the middle of the top of the protective cover 14, a negative pressure pipe 34 connected and installed outside the through hole, and an exhaust fan 35 installed inside the through hole. The other end of the negative pressure pipe 34 is connected and installed in the purification box, which can absorb the gas inside the operating box 1. When the protective cover 14 is distributed on the top of the operating box 1 and the exhaust fan 35 inside the through hole is driven, the gas inside the operating box 1 can be absorbed into the negative pressure pipe 34, concentrated in the purification box, and purified to avoid air pollution.

[0026] Furthermore, a rectangular groove is provided in the middle of the second chuck 24, and a rectangular shaft 26 is movably installed in the rectangular groove. One end of the rectangular shaft 26 is fixedly installed to the side wall of the clamp 3 on one side. A spring 27 is sleeved on the outer wall of the rectangular shaft 26. The spring 27 is fixedly installed on both sides of the second chuck 24 and the side wall of the clamp 3, respectively, so as to support the second chuck 24. The spring 27 sleeved on the outer side of the rectangular shaft 26 can compress the second chuck 24 to ensure that the side wall of the second chuck 24 is always in contact with the side wall of the first chuck 23.

[0027] In use, the waterproof backing board to be sprayed is first placed between the two sets of clamps 3, and the extrusion assembly is driven to firmly position the waterproof backing board between the two sets of clamps 3. The drive motor 11 drives the transmission component 12 to rotate. Since the transmission component 12 meshes with the driven gear 2 on the outside of the rotating drum 21, the rotating drum 21 is connected to the first rotating shaft fixedly installed at the bottom of the connecting frame 13 through the transmission belt assembly 25. This can drive the protective cover 14 on the top of the operating box 1 to rotate in any direction, effectively blocking the sprayed paint from splashing. At the same time, when the operator drives the drive motor 11 to rotate the transmission component 12 in the opposite direction, the driven gear 2 meshing with the transmission component 12 will synchronously drive the first chuck 23 to rotate in the opposite direction. As the first chuck 23 rotates in the opposite direction, the teeth on the first chuck 23 will... Engaging with the teeth of the second chuck 24, it synchronously drives the internal rectangular shaft 26 of the second chuck 24 to rotate, thereby driving the waterproof backing plate inside the two sets of clamps 3 to rotate in one direction. This allows the operator to spray the surface of the waterproof backing plate comprehensively through the operating slot. At the same time, a screw 31 is installed through a screw hole, and an extrusion plate 32 is rotatably installed at the other end of the screw 31. When the operator places the waterproof backing plate to be sprayed between the two sets of clamps 3, he can continuously tighten the screw 31 in the screw hole to extrude the extrusion plate 32 rotatably installed at one end of the screw 31, ensuring that both sides of the waterproof backing plate are tightly attached to the side walls of the two sets of clamps 3. This ensures that the waterproof backing plate is firmly fixed between the two sets of clamps 3, making it convenient for the operator to spray the surface of the waterproof backing plate.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
