Description

Technical Field

[0001] This utility model relates to the field of spraying devices, specifically a wall paint spraying device. Background Technology

[0002] A wall paint spraying device is a piece of equipment used to evenly spray wall paint onto a wall surface. It pressurizes the paint by controlling the airflow and delivers the paint to the spray gun through a high-pressure hose. The spray gun then atomizes the paint and releases it onto the wall surface. This device mainly consists of a feeding device, a spray gun, and an atomization source. In current wall paint spraying, the operator usually holds the spray gun and moves it up and down to spray the wall. This method requires repeated up-and-down and left-and-right movements of the spray gun, which can easily tire the operator's wrists and arms. Uneven movements can also affect the quality of the spraying.

[0003] To address the aforementioned issues, a wall paint spraying device with Chinese Patent Publication No. CN213329906U describes a method where the wall paint to be sprayed is placed in a paint bucket. The device moves to the position of the wall to be sprayed, and an electric telescopic rod drives a piston to move to the right. The piston's rightward movement draws the paint into the cylindrical bucket. The piston then moves to the left, pressing the paint into the outlet pipe and spraying it onto the wall surface through a high-pressure nozzle. When the crossbar pushes the guide block to the left via the L-shaped rod, the telescopic frame extends upward, causing the high-pressure nozzle to move upward. In other words, during the spraying process, the high-pressure nozzle continuously sprays paint and moves upward.

[0004] While the comparative patent solved the problem of repeated up-down and left-right movement of the spray gun, which easily fatigued the operator's wrists and arms, and affected the spraying quality when the movement was uneven, the device could only control the nozzle to move up and down. As a result, the spraying range of the nozzle was relatively narrow, and the operator had to frequently move the position of the support plate, which caused considerable trouble for the operator and reduced the practicality of the device.

[0005] Regarding the aforementioned technologies, this device has the drawback of only being able to control the nozzle to move up and down, resulting in a relatively narrow spraying range. It also requires operators to frequently move the support plate, causing considerable inconvenience to the operators and reducing the practicality of the device. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a wall paint spraying device that can control the nozzle to move left and right, resulting in a wider spraying range. This eliminates the need for operators to frequently move the support plate, thus reducing inconvenience and improving the device's practicality. It also solves the problem that only the nozzle can be controlled to move up and down, resulting in a narrower spraying range and requiring frequent repositioning of the support plate, which reduces the device's usability.

[0008] (II) Technical Solution

[0009] To achieve the goal of controlling the left and right movement of the nozzle, thus enabling a wider spraying range and reducing the need for frequent repositioning of the support plate by the operator, thereby improving the device's practicality, this utility model provides the following technical solution: A wall paint spraying device includes a housing. A machine box is fixedly connected to the top of the housing. A first motor is fixedly connected to the inner wall of the machine box. A threaded rod is fixedly connected to the output end of the first motor via a coupling. A limit block is fixedly connected to the top of the threaded rod. A lifting plate is threadedly sleeved on the outer wall of the threaded rod. A moving groove is formed on the front of the lifting plate. A second motor is slidably connected to the inner wall of the moving groove. A rotating shaft is fixedly connected to the output end of the second motor via a coupling. The outer wall of the rotating shaft... A gear is fixedly fitted, and a toothed plate is fixedly connected to the inner bottom wall of the moving groove. A pump body is fixedly connected to the top of the box, and a discharge pipe is fixedly connected to the discharge port of the pump body. A nozzle is fixedly connected to one end of the discharge pipe. By extending and retracting the telescopic rod, the lifting plate can be limited to vertical movement, thus the lifting plate can only move up and down. When the second motor drives the threaded rod to rotate, the lifting plate will move upward. When the second motor drives the gear to rotate, the gear can move as it rotates because the toothed plate meshes with the gear. Thus, the device can drive the nozzle to move up and down, and also drive the nozzle to move left and right. This results in a wider spraying range for the nozzle, eliminating the need for operators to frequently move the support plate, thus reducing inconvenience for operators and improving the practicality of the device.

[0010] In a preferred embodiment of this invention, a telescopic rod is fixedly connected to the bottom of the lifting plate, and the top of the telescopic rod is fixedly connected to the top of the housing. The extension and retraction of the telescopic rod limits the vertical movement of the lifting plate, thus restricting its movement to vertical. Consequently, when the second motor drives the threaded rod to rotate, the lifting plate moves upward.

[0011] As a preferred technical solution of this utility model, the inner side wall of the moving groove is provided with a channel, the rotating shaft is slidably sleeved with the channel, the top of the housing is inlaid with a bearing, the coupling of the second motor is rotatably sleeved with the bearing, and thus the rotating shaft can extend to the outside of the lifting plate.

[0012] As a preferred technical solution of this utility model, the toothed plate is meshed with the gear, and one end of the nozzle is rotatably connected to one end of the rotating shaft. When the second motor drives the gear to rotate, the gear can move when it rotates because the toothed plate is meshed with the gear.

[0013] As a preferred technical solution of this utility model, the bottom of the box is provided with rollers, and the top of the box is fixedly sleeved with a feed pipe. The device can be moved by the rollers, and the paint raw materials can be added to the inside of the box through the feed pipe.

[0014] As a preferred embodiment of this utility model, the pump body has a fixedly connected suction pipe at its inlet, and the suction pipe is fixedly sleeved with the housing. The pump body can operate by entering the outlet pipe through the suction pipe and spraying material through the nozzle.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a wall paint spraying device, which has the following beneficial effects:

[0017] 1. By extending and retracting the telescopic rod, the lifting plate can be limited to vertical movement. Thus, the lifting plate can only move up and down. When the second motor drives the threaded rod to rotate, the lifting plate will move upward. When the second motor drives the gear to rotate, the gear plate meshes with the gear, allowing the gear to move while rotating. This enables the device to move the nozzle up and down, as well as left and right, resulting in a wider spraying range. It eliminates the need for operators to frequently move the support plate, thus reducing inconvenience and improving the practicality of the device.

[0018] 2. With its housing, rollers, feed pipe, and pump, the device can be moved by the rollers, and the paint material can be added to the housing through the feed pipe. The pump can then draw the paint through the suction pipe into the discharge pipe, and the paint can be sprayed through the nozzle. This further meets the usage requirements of the device and provides effective assistance, making it worthy of promotion. Attached Figure Description

When the second motor 12 drives the gear 14 to rotate, the gear plate 15 is meshed with the gear 14, so the gear 14 can move when it rotates. Thus, the device can drive the nozzle 19 to move up and down, and can also drive the nozzle 19 to move left and right.
