Description

Technical Field

[0001] This utility model relates to the field of exterior wall coating technology, specifically to an exterior wall coating primer coating equipment. Background Technology

[0002] Exterior wall coating primer application equipment typically includes mechanical devices for evenly applying coatings to the exterior surface of buildings. The application process for exterior wall coatings generally includes steps such as substrate preparation, applying primer, intermediate coats, and topcoat application. The role of the primer is to provide good adhesion and sealing, preventing alkaline substances inside the wall from damaging the coating. Before application, it is necessary to ensure that the substrate surface is clean, free of dust and oil, and to perform appropriate sanding and repairs.

[0003] Common exterior wall coating primer application equipment consists of a storage tank, pipes, and a spraying mechanism. In use, the mixed paint is first injected into the storage tank, and then sprayed out through the pipes and spraying mechanism. However, in order to ensure the spraying quality, this method uses a transmission mechanism such as a lead screw to drive the horizontal movement of the nozzle to ensure the uniformity of the coating. However, since the nozzle is fixed, it cannot compensate for small errors in its movement trajectory, which will cause streaks or unevenness in the coating when applying paint over a large area. This cannot meet the working requirements of primer application equipment. Therefore, an exterior wall coating primer application equipment is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an exterior wall coating primer application device to solve the technical problem that the fixed installation of the nozzles prevents the nozzles from self-compensating for minor errors in their movement trajectory, which can cause stripes or unevenness in the coating when applying it over a large area.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an exterior wall coating primer application device, comprising:

[0008] The base has a first motor mounted on its right end via a bracket, and the rotor of the first motor passes through the corresponding position of the base. The rotor of the first motor is coaxially connected to a lead screw.

[0009] A movable seat is screwed onto the outside of the lead screw. An L-shaped seat is installed on the top of the movable seat. A second motor is installed on the front side of the top of the L-shaped seat. The rotor of the second motor is coaxially connected to a drive rod.

[0010] A transmission rod is connected to the outer end of a drive rod via a bearing. A hinge rod is mounted on the outer end of the transmission rod via a bearing. A bracket is connected to the top rear side of the L-shaped seat, and a transmission pin is inserted inside the bracket. The bottom end of the transmission pin is connected to the top outer side of the hinge rod.

[0011] The nozzle is inserted inside the transmission pin, and a storage tank is mounted on the lower left side of the L-shaped seat via a foot bracket.

[0012] Preferably, a fan-shaped plate is sleeved on the lower outer side of the transmission pin, and the top of the fan-shaped plate is connected to the corresponding position of the bracket. The front end of the nozzle is connected to a mast, which improves the stability of the nozzle when it swings left and right.

[0013] Preferably, an arc-shaped slide rail is installed on the front side of the upper surface of the fan-shaped plate, and a bottom rod is connected to the bottom of the mast. The bottom end of the bottom rod is inserted into the arc-shaped slide rail, and a ball bearing is installed at the bottom end of the bottom rod, so that the nozzle is more stable during the swinging process, preventing vibration and improving the uniformity of the coating during spraying.

[0014] Preferably, the left side of the nozzle is connected to the top of the storage tank via a telescopic hose. The added telescopic hose facilitates the operation of the nozzle without interference. The left end of the lead screw is connected to the corresponding position on the inner side of the base via a ball bearing, which improves the stability of the lead screw during rotation.

[0015] Preferably, guide rods are inserted on both the front and rear sides of the interior of the movable seat, and the left and right ends of the guide rods are connected to the corresponding positions on the inner side of the base. The number of guide rods on each side is 1-2 sets, which improves the stability of the movable seat during movement.

[0016] Preferably, a slider is installed at the bottom center of the movable base, and a guide rail is installed on the lower inner side of the base corresponding to the slider, with the slider inserted inside the guide rail.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides an exterior wall coating primer application equipment, which has the following beneficial effects:

[0019] This exterior wall paint primer coating equipment uses a second motor to drive the rotation of a drive rod, which in turn drives the rotation of a hinge rod via a transmission rod. This allows the transmission pin to rotate left and right, enabling reciprocating spraying of the paint. This expands the spraying width, reduces the number of sprays, and improves construction efficiency. At the same time, the oscillating nozzle can better cover large wall areas, reduce operational complexity, and help achieve a more uniform coating effect. In addition, the oscillating nozzle can adapt to slight unevenness on the wall surface, naturally filling in uneven areas through the oscillating motion. Attached Figure Description

[0028] Please see Figure 1 The right end of the base 1 is equipped with a first motor 2 via a bracket, and the rotor of the first motor 2 passes through the corresponding position of the base 1. The rotor of the first motor 2 is coaxially connected to a lead screw 3.

Figure 4 The top rear side of the L-shaped seat 5 is connected to a bracket 11, and a transmission pin 12 is inserted inside the bracket 11. The bottom end of the transmission pin 12 is connected to the top outer side of the hinge rod 10.

[0031] The nozzle 13 is inserted inside the transmission pin 12. A storage tank 6 is mounted on the lower left side of the L-shaped seat 5 via a bracket. A fan-shaped plate 15 is fitted onto the lower outer side of the transmission pin 12, and the top of the fan-shaped plate 15 is connected to the corresponding position of the bracket 11. A mast 14 is connected to the front end of the nozzle 13. An arc-shaped slide rail 16 is installed on the front side of the upper surface of the fan-shaped plate 15. A base rod 17 is connected to the bottom of the mast 14, and the bottom end of the base rod 17 is inserted into the arc-shaped slide rail 16. A ball bearing is installed at the bottom end of the base rod 17. The left side of the nozzle 13 is connected to the top of the storage tank 6 via a telescopic hose. The left end of the lead screw 3 is connected via... The ball bearing is connected to the corresponding position on the inner side of the base 1. The second motor 7 drives the drive rod 8 to rotate, which in turn drives the hinge rod 10 to rotate through the transmission rod 9. This allows the transmission pin 12 to rotate left and right, enabling reciprocating spraying when spraying paint. This can expand the spraying width, reduce the number of sprays, and improve construction efficiency. At the same time, the swinging nozzle 13 can better cover large areas of the wall, reduce the complexity of operation, and help achieve a more uniform coating effect. In addition, the swinging nozzle 13 can adapt to the slight unevenness of the wall surface and naturally fill the unevenness through the swinging motion.

[0033] This design uses a second motor 7 to drive the rotation of the drive rod 8, which in turn drives the rotation of the hinge rod 10 via the transmission rod 9. This allows the transmission pin 12 to rotate left and right, enabling reciprocating spraying during paint application. This expands the spraying width, reduces the number of sprays, and improves construction efficiency. At the same time, the oscillating nozzle 13 can better cover large wall areas, reducing operational complexity and contributing to a more uniform coating effect. Furthermore, the oscillating nozzle 13 can adapt to slight unevenness on the wall surface, naturally filling in uneven areas through its oscillating motion.
