Description

Technical Field

[0001] This utility model relates to the field of coating tool technology, and in particular to an intelligent automatic feeding roller brush. Background Technology

[0002] In the current field of coating application technology, two main types of coating tools are commonly used: traditional manual rollers and automated sprayers. Manual rollers are widely used due to their low cost and broad applicability; however, frequent dipping of paint after each stroke results in low efficiency, high labor costs, and paint dripping during dipping, leading to paint waste and negatively impacting the hygiene of the work site and operators. While sprayers offer higher coating quality and efficiency with continuous paint supply, their high equipment cost and demanding operator skills, coupled with paint atomization that pollutes the air and affects operators, limit their wider application. Furthermore, sprayers have limitations in handling multiple colors and outdoor applications, as well as the inconvenience of working at heights—all problems that urgently need to be addressed in current technology. Therefore, it is necessary to develop a new coating application tool that combines the advantages of both methods to achieve a highly efficient, environmentally friendly, easy-to-operate, and cost-effective coating application technology.

The Hall element 6 is fixedly installed at an off-center position on the limiting end 5 of the handle 3, and the permanent magnet 7 is fixed on the ring 2. The ring 2 is fitted into an annular groove 9 on one side of the brush roller 1 and rotates synchronously with the brush roller 1. The installation positions of the Hall element 6 and the permanent magnet 7 correspond, creating a sensing change in distance during rotation. When the brush roller 1 rotates, the Hall element 6 installed on the limiting end 5 detects the permanent magnet 7 on the ring 2. The magnetic field changes, and the changing magnetic field is converted into a change in output voltage. The control device 8 is a chipset that receives and processes the level signal from the detection sensor, and is a modular control unit.

[0021] Preferably, this utility model provides an intelligent automatic feeding roller brush, wherein the outer wall of the annular groove 9 is a cylindrical insert structure, which is sealed to the inner cavity of the brush roller 1. The oil seal hole 10 is located at the center of the inner side of the annular groove 9. The curved surface of the contact surface between the ring 2 and the annular groove 9 is provided with interlocking anti-slip teeth 15 to prevent the ring 2 from slipping in the annular groove 9 of the brush roller 1 and affecting the action detection. Alternatively, the ring 2 and the annular groove 9 are an integral structure.

[0022] Preferably, this utility model provides an intelligent automatic feeding roller brush. The portion of the handle 3 below the limiting end 5 bends downwards, and after bending to the off-center part of the brush roller 1, it forms a straight handle 16 of a certain length. The straight handle 16 is covered with a handle sleeve for easy hand gripping. The straight handle 16 is a telescopic control lever, which can perform brushing operations at a certain height. The straight handle 16 is equipped with a work switch 17, which is connected to the wire between the Hall element 6 and the control device 8 to control the start and stop of feeding at any time during the brushing operation.

[0023] Preferably, this utility model provides an intelligent automatic feeding roller brush. The brush roller 1 has a cylindrical cavity inside which a balance bracket 18 is provided. The balance bracket 18 is a hollow support frame structure with support feet 22 to hold the cylindrical cavity inside the brush roller 1 in place. A retaining ring 19, a highly elastic C-shaped ring tube structure, is located at the center of the balance bracket 18 to hold the straight end of the handle 3, thus fixing the brush roller 1 and preventing it from coming off. During rotation, the brush roller 1 will rotate around the retaining ring 19 and the oil seal 4. The straight end of the handle 3 has a slightly smaller diameter opening for easy installation of the brush roller 1. The brush roller 1 is a replaceable consumable, facilitating replacement due to wear or switching between brush rollers of different colors. A strip-shaped opening 23 is also provided on the straight rod for uniform material discharge.

[0024] As a preferred embodiment, the present invention provides an intelligent automatic feeding roller brush in which the annular groove 9 and the balance bracket 18 are integrated structures.

[0025] Preferably, this utility model discloses an intelligent automatic feeding roller brush. The control device 8 is equipped with a first switch 11, a second switch 12, and a speed control knob 13. The first switch 11 is a power switch, which connects the power supply when closed and disconnects it when open. The second switch 12 is a motor switch for the feeding pump 14, which keeps the feeding pump 14 motor running when closed to facilitate equipment cleaning. The speed control knob 13 is a speed sensor used to perform pulse width modulation on the feeding pump 14 motor to control the feeding pump 14 to feed an appropriate amount of material, avoiding overfeeding and overflow or underfeeding and insufficient material supply. The Hall element 6 is connected to the control device 8 via a wire.

[0026] As a preferred embodiment, the present invention provides an intelligent automatic feeding roller brush, wherein the control device 8 is further provided with an indicator light 20, which consists of a red indicator light and a blue indicator light. When switch 11 is closed and the power is connected, the red indicator light illuminates; when switch 212 is closed and the feed pump 14 motor is running continuously, the blue indicator light illuminates.

[0027] In practical use, the tail end of the handle 3 is connected to the feed pump 14 through a conduit, the suction end 21 of the feed pump 14 is placed into the material bucket, and the control device 8 is connected to the power supply through a wire.

[0028] In use, connect the power supply, close switch 11, the red indicator light will illuminate, and the device will enter the working state. Then close switch 12, the feed pump 14 motor will rotate, and the feed pump 14 will transport the paint in the bucket to the feeding pipe inside the handle 3. When the paint overflows from the gap between the bristles through the cavity wall holes of the brush roller 1, open switch 12, and the feed pump 14 motor will stop rotating. Then, open the working switch 17, and the operator holds the straight handle 16 and rolls the brush roller 1 into contact with the wall. During operation, as the brush roller 1 rolls, the detection sensor detects the changes in the operation of the brush roller 1 and outputs a detection signal. The control device 8 receives and processes the detection signal from the detection sensor and controls the feed pump 14 motor to rotate. That is, if the brush roller 1 continues to roll, the feed pump 14 will continue to supply paint; if the brush roller 1 stops rolling, the feed pump 14 will stop supplying paint. In this way, intelligent feeding based on automatic recognition of the working action can be achieved.

[0029] During use, if the material supply is insufficient or excessive, adjust the speed control knob 13 to the appropriate material supply. During operation, disconnect the operation switch 17. The control device 8 will not receive the detection signal from the detection sensor, and the automatic material supply will stop. At this time, the wall surface of the roller can be further touched up and coated evenly.

[0030] When the painting is finished or the paint color needs to be changed midway, put the suction end 21 of the feed pump 14 into the clean water bucket, close the second switch 12, and the motor of the feed pump 14 will run continuously. The feed pump 14 will deliver the clean water in the clean water bucket to the feeding pipe of the handle 3, and flush out the residual paint from the gaps between the brush bristles through the cavity wall holes of the brush roller 1. After rinsing clean, turn off the second switch 12. If the paint color needs to be changed, clean the suction end of the feed pump 14 and put it into another paint bucket for mixing the color. Close the second switch 12 to push the paint of the new color onto the brush roller 1, and then turn off the second switch 12 to standby operation.

[0031] When replacing brush roller 1, hold the limiting end 5 of handle 3, pull out the old brush roller, remove the ring 2 with permanent magnet and insert it into the ring groove 9 of the new brush roller, insert the straight rod of handle 3 into the retaining ring of the new brush roller, embed the oil seal 4 and push it into the oil seal hole 10, and press the ring 2 against the limiting end 5 of handle to complete the installation.

[0032] It should be noted that the switch 11, switch 2 12 and speed control knob 13 are the control terminals of the control device 8, so as to facilitate the operation and control of various operation links such as material feeding standby and cleaning equipment. This utility model utilizes the Hall effect principle to convert the changing magnetic field into a change in output voltage, and then uses the output to control and regulate the motor of the feed pump 14, so as to realize intelligent detection operation. Its circuit control can be freely modulated and forms a modular control unit.

[0033] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
