Description

Technical Field

[0001] The utility model belongs to the technical field of building wall paint spraying, and in particular relates to a building paint spraying device. Background Art

[0002] In order to protect the wall from erosion by factors such as sunlight, wind, rain, and pollution, extend the service life of the wall, and reduce the frequency and cost of maintenance and repair, it is necessary to spray paint on the wall of the building.

[0003] Currently, when spraying on building walls, it is necessary to move the nozzle to make the nozzle move back and forth on the wall to ensure that the paint can cover the entire wall. However, the nozzle needs to move a whole stroke from top to bottom to complete the spraying of the set height on the wall. Since the reciprocating movement of the nozzle is long, the spraying speed is low, which affects the spraying efficiency.

[0004] For example, Chinese utility model patent with patent document number CN217734738U discloses a building exterior wall spraying device. During spraying, the slider can drive the second material pipe to move up and down under the drive of the screw, so that the spray port moves up and down under the drive of the second material pipe to spray the building exterior wall. In this way, there is no need to spray the wall manually, which reduces the danger during spraying.

[0005] However, in the above patent, when the screw drives the second material tube to move up and down for spraying, the second material tube needs to move a whole stroke, that is, the entire length of the screw, to achieve a complete spraying operation on the wall. Since the second material tube has a long stroke when moving up and down, the spraying efficiency is low.

[0006] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the present invention.

[0036] In the description of the present invention, the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0038] The utility model provides a spraying device for building paint, wherein a transmission wheel and a strip transmission component are arranged on a vertical support frame, and a spraying assembly is respectively fixedly connected to two oppositely arranged sections of the strip transmission component located between two transmission wheels. When the transmission wheel rotates, the closed strip transmission component moves, and the two sections located on the oppositely arranged sections between the two transmission wheels move in opposite directions, so that the two spraying assemblies move up and down in opposite directions, thereby shortening the movement stroke of the spraying assemblies.

[0039] Specifically, Figure 1-5 As shown, see Figure 3 The spraying device of building coating comprises a spraying device body (not shown in the figure) and a vertical support frame 2 arranged on the spraying device body for the spraying assembly 1 to move up and down, and the upper and lower ends of the vertical support frame 2 are respectively connected to two transmission wheels 3 with the same diameter, and the two transmission wheels 3 are connected by a closed strip transmission component 4. In the present embodiment, the transmission wheel 3 is a belt pulley, and the strip transmission component 4 is a belt adapted to the belt pulley. In other embodiments, the transmission wheel 3 can also be a sprocket, and at this time, the strip transmission component 4 is a transmission chain adapted to the sprocket. In this way, when one of the transmission wheels 3 rotates, the other transmission wheel 3 will be driven to rotate through the strip transmission component 4. In this process, the two sections of the strip transmission component 4 located relatively between the two transmission wheels 3 move in opposite directions. Therefore, when a spraying assembly 1 is fixedly connected to the two sections by a driving block 5, the rotation of the transmission wheel 3 can make the two spraying assemblies 1 move up and down in opposite directions, so that the two spraying assemblies 1 can complete the stroke on the vertical support frame 2 together. Compared with the prior art, in which a spraying component 1 needs to run the entire spraying stroke completely, in the technical solution of the utility model, each spraying component 1 only needs to run half of the stroke, thereby improving the spraying efficiency.

[0040] It should be noted that, in this embodiment, the spray assembly 1 is a combination of an existing spray pipe and a nozzle for achieving the purpose of spraying paint. In other embodiments, it can also be a spray gun, as long as it is a component that can achieve the purpose of spraying paint.

[0041] In order to further ensure the balance of the movement of the spray assembly 1 on the vertical support frame 2, a slide rail 19 is provided in the middle of the vertical support frame 2, and the two drive blocks 5 slide with the slide rail 19 respectively, so that when the belt movement drives the drive block 5 to move up and down, the drive block 5 slides along the slide rail 19 at the same time, so that the spray assembly 1 can run more smoothly.

[0042] In order to facilitate driving the transmission wheels 3 , a driving assembly for driving one of the transmission wheels 3 to rotate is provided at the bottom of the vertical support frame 2 .

[0043] like Figure 1As shown, in this embodiment, the driving assembly specifically includes a supporting base 6 , a first rotation driving source 7 , a first transmission gear 8 , and a second transmission gear 9 .

[0044] The support base 6 is integrally fixedly connected to the bottom end of the vertical support frame 2, the first rotation drive source 7 is fixedly connected to the support base 6, the first transmission gear 8 is rotationally connected to the vertical support frame 2, and the first transmission gear 8 is coaxially fixedly connected to the transmission wheel 3 at the bottom end of the vertical support frame 2; the first transmission gear 8 and the transmission wheel 3 are respectively located on both sides of the vertical support frame 2; the second transmission gear 9 is rotationally connected to the vertical support frame 2, and the second transmission gear 9 is meshed with the first transmission gear 8 for transmission; the first rotation drive source 7 is used to drive the second transmission gear 9 to rotate forward and reverse.

[0045] like Figure 4 As shown, in this embodiment, the first rotation driving source 7 drives the second transmission gear 9 to rotate forward and reversely through a transmission unit, and the transmission unit specifically includes a first transmission rack 10, a slideway 11 and a connecting rod 12.

[0046] Among them, a clamping protrusion 1001 is provided on one side of the first transmission rack 10, and a slide groove matching the shape of the clamping protrusion is provided on the corresponding vertical support frame 2, and the clamping protrusion is clamped in the slide groove and slidably connected with the vertical support frame 2. The first transmission rack 10 is meshed with the second transmission gear 9 for transmission; the slideway 11 is vertically fixed on the first transmission rack 10, and the slideway 11 has a sliding groove 1101 arranged along the length direction of the slideway 11; one end of the connecting rod 12 is fixedly connected to the output shaft of the first rotation driving source 7, and the other end is provided with a sliding column 1201, which extends into the sliding groove 1101 and slides with the sliding groove 1101.

[0047] Specifically, during operation, the first rotation driving source 7 is a motor, which drives the connecting rod 12 to rotate. The end of the connecting rod 12 away from the motor slides on the slideway 11, thereby driving the first transmission rack 10 to slide left and right, and then drives the first transmission gear 8 to rotate through the second transmission gear 9, thereby driving the bottom pulley to rotate.

[0048] In this embodiment, the first rotation driving source 7 drives the second transmission gear 9 to rotate forward and reversely. The motor requirement is not high. It is only an ordinary motor that normally outputs a rotation driving force in one direction. In other embodiments, the transmission unit in this embodiment may not be used, and a servo motor may be used to directly connect to the second transmission gear 9 to control the forward and reverse rotation of the second transmission gear 9. In this way, the speed delivered by the servo motor is directly driven to rotate the pulley after being adjusted in two stages by the second transmission gear 9 and the first transmission gear 8.

[0049] like Figure 1As shown, the spraying device for building paint also includes a fixed bracket 13, which has a horizontal sliding platform 1301 and two sliding rods 1302 located above the horizontal sliding platform 1301. The horizontal sliding platform 1301 and the two sliding rods 1302 are fixedly connected by two oppositely arranged L-shaped fixing parts 1303. The fixed bracket 13 is fixedly connected to the spraying device body for the vertical support frame 2 to move left and right to increase the width range of the spraying.

[0050] like Figure 2 As shown, a sliding block 14 is fixedly provided at the bottom of the support base 6, the sliding block 14 is sleeved on the top of the horizontal sliding platform 1301 and is slidably connected to the horizontal sliding platform 1301, a second transmission rack 15 is provided at the bottom of the horizontal sliding platform 1301, and a third transmission gear 16 is rotatably connected to the support base 6, the third transmission gear 16 is driven by a second rotating driving source 21 fixedly connected to the support base 6, and the third transmission gear 16 is meshed with the second transmission rack 15 for transmission, so that when the second rotating driving source 21 drives the third transmission gear 16, it can drive the vertical support frame 2 to move left and right on the horizontal sliding platform 1301.

[0051] A feed pipe 17 is spirally sleeved on the sliding rod 1302, one end of the feed pipe 17 is connected to the spray assembly 1, and the other end is connected to the feed cylinder (not shown in the figure) in the coating device body, which is used to supply paint to the spray assembly 1. The purpose of spirally winding the feed pipe 17 on the feed pipe 17 is to facilitate the spraying operation process. The movement of the spray assembly 1 pulls the feed pipe 17 to stretch or shrink, so that the feed pipe 17 moves synchronously with the spray assembly 1.

[0052] In order to further improve the stability of the movement of the vertical support frame 2, a sliding block 18 is slidably connected to the sliding rod 1302, and the sliding block 18 is fixedly connected to the vertical support frame 2 through a connecting rod 20, that is, the vertical support frame 2 also moves along the sliding rod 1302 during the process of moving left and right along the horizontal sliding platform 1301.

[0053] like Figure 5 As shown, the sliding block 18 is specifically a U-shaped structure, and the two arms of the U-shaped structure are provided with through holes, which are sleeved on the sliding rod 1302. The feed pipe 17 passes through the U-shaped structure and is connected to the spray assembly 1, so as to ensure the stability of the feed pipe 17 during the movement and prevent the feed pipe 17 from getting tangled and blocking the feeding.

[0054] Specifically, during the use of the utility model, the first rotating drive source 7 is first used to drive the first transmission gear 8 to rotate through the transmission unit. The rotation of the first transmission gear 8 realizes the driving of the bottom pulley, and then drives the top pulley to rotate through the belt. During the rotation of the two pulleys, the two spraying assemblies 1 will be driven to move simultaneously to spray the wall in the set area. At the same time, under the action of the second rotating drive source 21, the entire vertical support frame 2 can be moved horizontally left and right along the horizontal sliding table 1301, so that the wall of the set width can be sprayed.

[0055] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
