Description

Technical Field

[0001] The utility model relates to the technical field of coating devices, in particular to a coating device for waterproof paint with controllable thickness. Background Art

[0002] Before the waterproof layer is constructed, the paint scraping and coil laying lines are drawn on the base layer according to the coil width, overlap width and laying direction. During the brushing construction, the waterproof coating is evenly applied to the base layer, and the thickness and uniformity of the coating layer need to be strictly controlled. The waterproof effect of the waterproof project is directly related to the quality of the coating and the brushing effect. When brushing, the number of brushing times should be determined based on the flow plasticity of the non-curing rubber asphalt coating or polyurethane coating. The principle of multiple thin coatings should be followed to avoid dripping and accumulation.

[0003] At present, the application of waterproof coatings such as non-curing rubber asphalt coatings or polyurethane coatings often uses flat scrapers, roller brushes and other tools. On the one hand, the use of such tools will result in uneven and discontinuous coating, which is easy to produce pores and bubbles, resulting in coating defects. On the other hand, it is impossible to control the waterproof coating to maintain the same thickness at all times, which seriously affects the bonding quality between the base layer and the waterproof membrane, and thus seriously affects the waterproof effect of the waterproof project. There are also highly automated waterproof coating brushing devices on the market, which save time and effort, but the devices are bulky, have high purchase and maintenance costs, and have a small scope of application.

[0004] At present, there is an urgent need for a painting device that can stably control the thickness of the paint and has a low cost, so as to improve the painting work quality of the operator. Utility Model Content

[0005] In view of the problems in the prior art that the waterproof coating brushing device is either difficult to stably control the coating thickness, or the device is bulky and has low applicability, the utility model provides a thickness-controllable waterproof coating brushing device with a simple structure and strong applicability. It can stably control the coating thickness and improve the waterproof effect of waterproof projects.

[0006] The technical solution of this utility model is as follows:

[0007] A thickness-controllable waterproof paint brushing device comprises a brush coater and a hand-held rod, one end of the hand-held rod is sleeved with a handle, and the other end is threadedly connected to a ball screw, a nut is sleeved on the shaft of the ball screw, and limit rings are respectively arranged at the upper and lower ends of the nut, the nut and the brush coater are detachably connected, the brush coater comprises an integrally connected brush coater fixing portion and a brush coater serrated portion, the brush coater serrated portion is provided with discontinuous and evenly spaced serrations, a bearing is sleeved on the end of the shaft away from the brush coater and is rotatably connected to a connecting rod through the bearing, and a roller is arranged at the other end of the connecting rod.

[0008] Furthermore, the angle formed between the shaft and the connecting rod ranges from 30° to 150°.

[0009] The angle formed between the shaft and the connecting rod refers to the angle between a ray from the bearing to the brush direction and a ray from the bearing to the roller direction, with the bearing as the vertex.

[0010] Furthermore, an angle ruler is provided on the connecting rod.

[0011] The angle tooth is a 360° carbon angle ruler, which is composed of two rulers and an axis. One of the rulers can rotate 360° around the axis at one end, and the angle formed with the other ruler is displayed on the screen set on the angle ruler, with an angle accuracy of ±0.3°. During installation, one ruler is fixed on the connecting rod, consistent with the length direction of the connecting rod, and the other ruler rotates around the axis to a direction parallel or perpendicular to the base. The angle between the two rulers is displayed on the screen, and then the vertical distance from the bottom edge of the sawtooth to the base is calculated according to the triangle internal angle calculation formula, which is the thickness of the waterproof coating applied.

[0012] Furthermore, a fixing ring is provided at the connection between the handle bar and the shaft.

[0013] The handle bar and the shaft are connected by threads to adjust the length of the handle bar, and the fixing ring is used to limit the position.

[0014] The fixing ring is a rubber ring with an opening. When the positions of the handle bar and the shaft are determined, the fixing ring is mounted on the connection between the handle bar and the shaft. The fixing ring is deformed through hinge connection, and the two ends of the opening of the rubber ring are brought closer and closer, thereby reducing the diameter of the rubber ring and increasing the pressure between the fixing ring and the handle bar, and between the fixing ring and the shaft, thereby fixing the positions of the handle bar and the shaft.

[0015] Furthermore, the handle is made of rubber, and the surface of the handle is provided with an anti-slip texture.

[0016] Improve holding stability.

[0017] Furthermore, screw holes are provided at the left and right ends of the nut, and corresponding screw holes are provided at the fixing part of the applicator. The nut and the fixing part of the applicator are detachably connected by screws.

[0018] After painting, the paint brush can be disassembled for cleaning or replacement.

[0019] Furthermore, the vertical distance from the sawtooth top angle to the bottom edge is 5-10 mm, and the angle of the sawtooth top angle is 60°.

[0020] Furthermore, a soft plastic shell is sleeved on the shaft, and the shell wraps around the bearing, the nut and part of the brush fixing part in sequence from the end of the shaft close to the hand-held rod to the direction of the nut. At the end of the shaft close to the hand-held rod and the rotational connection between the bearing and the connecting rod, through holes are respectively left at the positions of the two limit rings and the projection position of the brush fixing part on the shell. The two parts of the shell are snap-connected, and the size of the through hole at the rotational connection between the bearing and the connecting rod on the shell matches the cross-sectional size of the connecting rod.

[0021] The setting of the shell can prevent the internal structure of the waterproof coating brushing device from being exposed to the outside, making it more beautiful and practical. The shell is made of soft plastic, and the operator is not easily damaged when the two parts of the shell are snapped and fixed multiple times and disassembled and separated. The size of the through hole at the hinge between the bearing and the connecting rod on the shell matches the cross-sectional size of the connecting rod. When the two parts of the shell are snapped together, the assembled shell can be fixedly supported on the connecting rod.

[0022] The beneficial effects of the utility model are:

[0023] The utility model provides a thickness-controllable waterproof coating brushing device with a simple structure. The extension lines of the shaft and the connecting rod form a triangle with the base layer. The nut on the ball screw drives the coating device to move linearly on the shaft without self-rotation, thereby changing the length of the side of the triangle where the axis is located, causing the angles of the two adjacent corners of the side of the triangle where the base layer is located to change, thereby adjusting the vertical distance from the sawtooth bottom edge to the base layer and determining the coating thickness of the waterproof coating. In addition, the combined arrangement of the connecting rod and the roller can improve the stability of the waterproof coating during the brushing operation, and the coating can be kept at the same thickness effortlessly during the entire operation, thereby reducing the waste of waterproof coating and improving the work efficiency of the operator.

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 without creative work should fall within the scope of protection of the present invention.

[0031] Example 1

[0032] Reference Figure 1-Figure 3 A waterproof coating brushing device with controllable thickness includes a coating brush 12 and a hand-held rod 2. A handle 1 is sleeved on one end of the hand-held rod 2. The handle 1 is made of rubber and has an anti-slip texture on the surface. The other end of the hand-held rod 2 is threadedly connected to a ball screw. A fixing ring 3 is provided at the connection. A nut 6 is sleeved on the shaft 4 of the ball screw. Limiting rings 5 ​​are provided at the upper and lower ends of the nut 6. The nut 6 is detachably connected to the coating brush 12. The coating brush 12 includes an integrally connected coating brush fixing portion 7 and a coating brush serrated portion 8. The coating brush serrated portion 8 is provided with discontinuous uniformly spaced Sawtooth, the vertical distance from the top angle of the sawtooth to the bottom edge is 10mm, and the angle of the top angle of the sawtooth is 60°. Specifically, screw holes are provided at the left and right ends of the nut 6, and the brush fixing part 7 is provided with corresponding screw holes. The nut 6 and the brush fixing part 7 are detachably connected by screws. A bearing 13 is provided on the end of the shaft 4 away from the brush 12, and is rotatably connected to the connecting rod 10 through the bearing 13. The angle formed between the shaft 4 and the connecting rod 10 has an angle range of 30°. An angle ruler 9 is provided on the connecting rod 10, and a roller 11 is provided at the other end of the connecting rod 10.

[0033] The vertical distances from the bottom edge of the sawtooth to the base layer (also the coating thickness of the waterproof coating) corresponding to several typical angles on the angle ruler 9 are listed by the designer in the manual, and a calculation formula is attached for the operator to adjust the position of the nut 6 on the shaft 4 accordingly at the operation site.

[0034] Before use, determine the thickness of the waterproof coating according to the specific operating conditions, refer to the instructions to determine the corresponding angle on the angle ruler 9, then adjust the non-rotating linear movement of the nut 6 on the shaft 4, and use it in conjunction with the angle ruler 9 to determine the corresponding position of the nut 6 on the shaft 4, and then use two limit rings 5 ​​to fix the nut 6. Because the shaft 4 is provided with a bearing 13, when the shaft 4 is rotating, the nut 6 drives the applicator 12 to move linearly on the shaft 4 without self-rotation, and the connecting rod 10 can remain stable. Then, according to the operator's body shape and usage habits, turn the hand-held rod 2, determine the position of the handle 1, and use the fixing ring 3 to fix the connection between the shaft 4 and the hand-held rod 2.

[0035] When in use, first apply a small amount of waterproof coating evenly on the base layer that has been coated with primer. The operator holds the handle 1 and pulls the waterproof coating brushing device to move in the direction of the roller 11. During the stable pulling process, the serrated portion 8 of the coating brush is in uniform and full contact with the waterproof coating, so as to form uniform, spaced strips of waterproof coating that meet the thickness requirements, so as to meet the thickness requirements of the waterproof coating.

[0036] Example 2

[0037] The difference from Example 1 is that the vertical distance from the top angle of the sawtooth to the bottom edge is 5 mm, and the angle range of the angle formed between the shaft 4 and the connecting rod 10 is 150°.

[0038] Example 3

[0039] The difference from Example 1 is that, referring to Figure 4 A soft plastic shell 14 is sleeved on the shaft 4, and the shell 14 wraps the bearing 13, the nut 6 and part of the applicator fixing part 7 in sequence from the end of the shaft 4 close to the hand-held rod 2 to the direction of the nut 6. Through holes are respectively reserved at the end of the shaft 4 close to the hand-held rod 2, the rotation connection between the bearing 13 and the connecting rod 10, the positions of the two limit rings 5 ​​and the projection position of the applicator fixing part 7 on the shell 14. The two parts of the shell 14 are snap-connected, and the size of the through hole at the rotation connection between the bearing 13 and the connecting rod 10 on the shell 14 matches the cross-sectional size of the connecting rod 10.

[0040] After the other parts of the waterproof coating brushing device are connected, the two parts of the shell 14 are snapped together, and the size of the through hole at the hinge between the bearing 13 and the connecting rod 10 on the shell 14 matches the cross-sectional size of the connecting rod 10. When the two parts of the shell 14 are snapped together, the assembled shell 14 can be fixedly supported on the connecting rod 10. When fine-tuning is required, the rotation of the shaft 4 does not affect the shell, and the operator can adjust the limit ring 5 through the through hole left on the shell.

[0041] Although the present invention is described in detail by referring to the accompanying drawings and in combination with the preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, a person skilled in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions shall be within the scope of the present invention. Any person skilled in the art who is familiar with the present technical field may easily think of changes or substitutions within the technical scope disclosed in the present invention, and these shall be within the scope of protection of the present invention.
