Description

Technical Field

[0001] This utility model relates to the field of coating device technology, and in particular to a roller coating device. Background Technology

[0002] Chinese patent number "CN221908106U" discloses a multifunctional roller coating device bottle, including a roller brush head. The roller brush head consists of a roller shaft and a plush sleeve fitted on the surface of the roller shaft. A composite support plate is fitted on the outer side of the roller brush head. A material storage device is provided at the bottom of the composite support plate. A stepped groove is provided on the inner side of the middle part of the composite support plate. A discharge groove is opened at the top of the stepped groove. The roller brush head, composite support plate, material storage device, discharge groove, flow-extending ring sleeve, and auxiliary discharge groove are combined to form a multifunctional roller coating device bottle. In use, it can be repeatedly assembled, disassembled, and reused. It integrates material placement and application into one unit. Compared with traditional large-volume coating devices, its flexibility and practicality are greatly improved. The integrated structure also makes it convenient for users to operate by themselves, and the user experience is also satisfied.

[0003] This device can be used for the production of roller coating. The coating is delivered to the surface of the roller head through the discharge chute to meet the function of coating the wall. However, the device does not have an efficient roller head spraying structure. During use, it is necessary to roll the roller head multiple times to cover it, which affects efficiency. At the same time, multiple coatings can easily produce different thicknesses, affecting the flatness of the wall and causing unnecessary waste. Therefore, an improvement is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of efficient roller brush head spraying structures, the need for multiple rolls to cover the roller brush head, which affects efficiency, and the potential for uneven thickness due to multiple coatings affecting the flatness of the wall and causing unnecessary waste. Therefore, this invention proposes a roller paint application device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a roller coating device, including a roller brush connecting sleeve with a lower opening structure, a connection port for cooperating with a paint bottle is provided on the upper part of the roller brush connecting sleeve, and a spraying structure is provided inside the connection port;

[0007] The spraying structure includes a discharge trough opened inside the connection port. The discharge trough is arranged in four groups in a diamond shape. A paint ring is fixedly connected inside the roller brush connecting sleeve. The discharge troughs are arranged symmetrically on the left and right sides inside the paint ring. The discharge troughs are arranged symmetrically on the front and back sides of the paint ring. The discharge trough is a circular channel structure that gradually increases in size from the connection port to the paint ring.

[0008] Preferably, the connection port has two sets of symmetrical guide channels inside, and the two sets of guide channels are respectively connected to the front and rear symmetrical discharge channels.

[0009] Preferably, the connection port has two sets of symmetrical auxiliary discharge ports inside, and the auxiliary discharge ports are interconnected with the coating ring.

[0010] Preferably, a roller brush assembly is rotatably connected to the lower opening of the roller brush connecting sleeve;

[0011] The roller brush assembly includes a roller brush shaft, a roller brush head is sleeved on the outer end face of the roller brush shaft, and limit plates are fixedly connected to both the left and right ends of the roller brush shaft.

[0012] Preferably, the roller brush connecting sleeve has roller brush slots on both the left and right sides, and the roller brush shaft is movably engaged into the inside of the roller brush slots.

[0013] Preferably, the front and rear sides of the roller brush connecting sleeve are provided with first wave lines, and the first wave lines rotate and abut against the outer end face of the roller brush head.

[0014] Preferably, the coating ring has second wavy lines on both its front and rear sides, and the second wavy lines rotate and abut against the outer end face of the roller brush head.

[0015] The roller coating device proposed in this utility model has the following advantages: the paint bottle can be fixed through the connection port, and the paint bottle and paint ring are connected by the cooperation of the discharge trough and auxiliary discharge port. The four sets of discharge troughs distributed in a diamond shape increase the paint capacity sprayed onto the roller brush head. At the same time, the annular channel can prevent clogging. During use, the two sets of discharge troughs inside the paint ring can cover most of the roller brush head surface. Then, a secondary spraying is performed through the discharge trough located outside the paint ring, thereby ensuring complete coverage of the roller brush head. At the same time, two sets of discharge troughs are set symmetrically outside the paint ring, so secondary spraying can be performed regardless of whether the roller brush head is rotating forward or backward. In this way, the roller brush head is completely covered with paint, which greatly reduces the occurrence of secondary coating during the use of the device.

[0016] By setting a second wavy line, the paint flowing out of the paint ring can be evenly applied. By setting a first wavy line, the paint flowing out of the paint ring can be evenly applied. At the same time, the first wavy line and the second wavy line can be staggered to ensure even application and avoid the situation where the paint flows to both ends when applying in a straight line.

[0017] By setting a roller brush slot, the roller brush can be easily removed to clean the residual paint in the discharge chute, preventing the paint from hardening and clogging the chute, and making it convenient for the next use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 A roller coating device includes a roller brush connecting sleeve 1 with a lower opening structure, a connecting port 2 for cooperating with a paint bottle is provided on the upper part of the roller brush connecting sleeve 1, and a spraying structure is provided inside the connecting port 2.

[0026] The spraying structure includes discharge troughs 6 located inside the connection port 2. These discharge troughs 6 are arranged in four sets in a diamond pattern. A paint ring 5 is fixedly connected inside the roller brush connecting sleeve 1. Symmetrical discharge troughs 6 are located inside the paint ring 5, and symmetrical discharge troughs 6 are located on the front and rear sides of the paint ring 5, respectively. The discharge troughs 6 are designed as annular channels that gradually increase in size from the connection port 2 towards the paint ring 5. The paint bottle can be fixed through the connection port 2. The four sets of diamond-shaped discharge troughs 6 increase the paint capacity sprayed onto the roller brush head 4. Simultaneously, the annular channel prevents clogging. During use, the two sets of discharge troughs 6 inside the paint ring 5 can cover most of the surface of the roller brush head 4. Then, a secondary spray is performed through the discharge troughs 6 located outside the paint ring 5, ensuring complete coverage of the roller brush head 4. The two sets of symmetrical discharge troughs outside the paint ring 5 allow for secondary spraying regardless of whether the roller brush head 4 rotates forward or backward. This ensures the roller brush head 4 is completely covered with paint, greatly reducing the occurrence of secondary coating during device use.

[0027] refer to Figure 2 In order to ensure that the brush head 4 rotates without shifting, a brush assembly is rotatably connected to the lower opening of the brush connecting sleeve 1.

[0028] The roller brush assembly includes a roller brush shaft 3, a roller brush head 4 is sleeved on the outer end face of the roller brush shaft 3, and limit plates 301 are fixedly connected to both the left and right ends of the roller brush shaft 3.

[0029] refer to Figure 2 To facilitate the disassembly of the roller brush head 4, roller brush slots 102 are provided on both the left and right sides of the roller brush connecting sleeve 1. The roller brush shaft 3 is movably inserted into the inside of the roller brush slot 102, and the roller brush head 4 can be inserted to facilitate the cleaning of the discharge trough 6.

[0030] refer to Figure 1 In order to improve the uniformity of paint application, first wave lines 101 are provided on both the front and rear sides of the roller brush connecting sleeve 1. The first wave lines 101 rotate and abut against the outer end face of the roller brush head 4.

[0031] refer to Figure 2 In order to apply the paint evenly, a second wave line 501 is provided on both the front and back sides of the paint ring 5. The second wave line 501 rotates and abuts against the outer end face of the roller brush head 4. At the same time, the first wave line 101 and the second wave line 501 can be staggered, so that the paint is applied more evenly. The wave design avoids the situation where the paint always goes to both ends when applying in a straight line.

[0032] refer to Figure 3 In order to ensure the flow rate of the front and rear discharge troughs 6, two sets of symmetrical guide channels 201 are provided inside the connection port 2. The two sets of guide channels 201 are respectively connected to the front and rear symmetrical discharge troughs 6.

[0033] refer to Figure 3 In order to increase the discharge flow rate, two sets of symmetrical auxiliary discharge ports 202 are provided inside the connection port 2. The auxiliary discharge ports 202 are connected to the coating ring 5.

[0034] Working method: During operation, the roller brush shaft 3 is inserted into the roller brush slot 102, and then the paint bottle is fixed through the connection port 2. The bottle body is squeezed and the roller brush head 4 is rolled on the wall surface to be painted. Through four sets of diamond-shaped discharge channels 6, the paint capacity sprayed onto the roller brush head 4 is increased. At the same time, the annular channel can prevent clogging. During use, the two sets of discharge channels 6 inside the paint ring 5 can cover most of the surface of the roller brush head 4. Then, a second spray is performed through the discharge channels 6 located outside the paint ring 5, thus ensuring complete coverage of the roller brush head 4. At the same time, two sets of symmetrical discharge channels 6 are set outside the paint ring 5, so that a second spray can be performed regardless of whether the roller brush head 4 is rotated forward or backward. In this way, the roller brush head 4 is completely covered with paint, which greatly reduces the occurrence of secondary coating during the use of the device, improves the use effect, and reduces waste.
