Description

Technical Field

[0001] This invention relates to the field of waterproof coating roller brush technology, and more specifically to a roller brush type waterproof coating application device. Background Technology

[0002] Waterproof coatings are a crucial component of building waterproofing projects, and their application quality directly impacts the waterproofing effect and lifespan of buildings. Among numerous application methods, roller coating has become one of the main methods for surface waterproofing due to its simplicity and wide applicability. However, current roller coating application techniques for waterproof coatings still have many limitations, severely restricting construction efficiency and quality.

[0003] Traditional waterproof coating application relies entirely on manual labor. Workers need to repeatedly bend over and dip the roller into the coating, which results in significant efficiency bottlenecks and ergonomic deficiencies.

[0004] In practice, workers need to re-dip the paint after painting 1-2 square meters, repeating this action 300-500 times in a standard 8-hour workday. This high-frequency repetitive action not only significantly increases the physical exertion of workers but also forces interruptions to the construction rhythm, severely impacting efficiency. Field measurements show that the pure working time of traditional roller coating accounts for less than 60%, with the remaining 40% wasted on auxiliary actions such as dipping and moving the machine.

[0005] Therefore, traditional roller coating construction relies entirely on manual labor. Construction workers need to repeatedly bend over to dip the paint, which is labor-intensive and inefficient. The force and amplitude of the roller brush are based on experience, and the thickness of the brush is difficult to control. Based on this, it is necessary to study a roller brush type waterproof coating construction device. Summary of the Invention

[0006] Therefore, the purpose of this invention is to provide a roller-type waterproof coating application device, which effectively solves the problems of existing waterproof coating roller application being difficult, laborious to operate, difficult to control the roller application force, and having poor roller application uniformity and low roller application efficiency.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: a roller-type waterproof coating application device, comprising a frame, a material spreading mechanism, a roller brush mechanism, and a drive mechanism; the bottom of the frame is provided with movable wheels; The fabric distribution mechanism is located on the front side of the vehicle frame and includes a hopper, a feeding pipe, a central shaft, an inner chamber, an outer chamber, and a drive shaft sleeve.

The upper part of the roller brush frame is slidably disposed in the groove via a sliding rod, and the roller brush is rotatably disposed on the roller brush frame. The drive mechanism includes a drive shaft, an eccentric sleeve, an eccentric rod, a drive rod, and a transmission wheel. The drive shaft is rotatably mounted on the frame and is connected to a drive motor mounted on the frame. The drive shaft can drive the eccentric sleeve and the transmission wheel to rotate. The eccentric sleeve is connected to the brush holder via the eccentric rod and the drive rod, forming an eccentric drive structure that causes the brush holder to reciprocate along the slide groove. The transmission wheel is connected to the drive shaft sleeve and drives the outer compartment to rotate around the inner compartment.

[0008] Furthermore, eccentric sleeves are fixedly provided at both ends of the drive shaft, and eccentric rods are fixed on the eccentric sleeves. The two ends of the drive rod are hinged between the roller brush frame and the ends of the eccentric rods to form an eccentric drive structure. A drive wheel is provided in the middle of the drive shaft. The drive wheel is connected to the drive motor via a belt. A transmission wheel is provided between the eccentric sleeve and the drive wheel. The transmission wheel is connected to the driven wheel provided on the drive shaft sleeve via a belt.

[0009] Furthermore, the drive shaft is connected to a follower shaft via a belt or gear transmission. Eccentric sleeves are provided at both ends of the follower shaft, and eccentric rods are fixed on the eccentric sleeves. The two ends of the drive rod are hinged between the roller brush frame and the ends of the eccentric rods, forming an eccentric drive structure. A drive wheel and a transmission wheel are fixed at both ends of the drive shaft, respectively. The drive wheel is connected to the drive motor via a belt, and the transmission wheel is connected to the driven wheel provided on the drive shaft sleeve via a belt.

[0010] Furthermore, both the follower shaft and the drive shaft are rotatably mounted on the frame via a fixed seat.

[0011] Furthermore, a flow guide platform is provided on the inner wall of the inner compartment, and the middle part of the inner compartment is fixed to the central axis by a support rod.

[0012] Furthermore, the two ends of the central shaft are fixed to the bottom of the vehicle frame by hangers, the outer compartment is fitted on the outside of the inner compartment, the drive shaft sleeve is fixed on the outside of the outer compartment and is rotatably connected to the central shaft by bearings, and the end of the drive shaft sleeve is provided with a driven wheel.

[0013] Furthermore, the roller brush includes a front roller and a rear roller, both of which are rotatably mounted on the roller brush frame.

[0014] Furthermore, the front roller includes multiple roller units connected by a coupling, and each roller unit is configured to correspond one-to-one with the fabric inlet.

[0015] Furthermore, it also includes a rolling adjustment mechanism, comprising an adjustment seat, an adjustment frame, and an elastic telescopic assembly; the rear side of the roller brush frame is a forward-inclined slope, the adjustment seat is fixed on the frame and is provided with a horizontal adjustment groove, the adjustment frame has a mounting surface parallel to the slope, the adjustment frame is adjustablely fixed in the adjustment groove by an adjustment block, and the two ends of the elastic telescopic assembly are hinged between the slope and the mounting surface; the roller brush frame includes a frame body, an adjustment rod, and an adjustment sleeve, wherein the frame body is provided with an adjustment rod, the adjustment rod is slidably fitted in the adjustment sleeve, the upper part of the adjustment sleeve is fixedly connected to a sliding rod, and the drive rod is connected to the adjustment sleeve.

[0016] Furthermore, a dovetail-shaped groove is provided on the inclined surface, one end of the elastic telescopic component is fixed to the mounting surface, and the other end is slidably disposed in the inclined groove by a slider limiter.

[0017] The beneficial effects of the above technical solution are: the present invention achieves automatic dotted distribution of paint by cooperating the rotating outer chamber and the fixed inner chamber of the cloth-laying mechanism, and performs the brushing operation by reciprocating motion of the roller brush, avoiding the intermittent operation of repeated manual dipping. At the same time, the mechanical feeding can greatly reduce auxiliary time and increase effective working time.

[0018] In terms of mechanical transmission, the drive mechanism controls the movement of the cloth and the roller brush simultaneously through a single motor, ensuring that the paint output speed and the roller brush frequency are precisely matched, reducing human rhythm differences, and significantly improving overall efficiency.

[0019] Meanwhile, by using a single motor for control and precisely controlling the transmission ratio, quantitative material distribution control and rolling frequency can be achieved. Specifically, the periodic alignment of the outer chamber material outlet and the inner chamber unloading outlet enables quantitative coating dispensing, avoiding fluctuations in coating quantity caused by manual dipping and ensuring consistent coating thickness. The eccentric drive structure enables the roller brush to reciprocate at a uniform speed, and the rolling adjustment mechanism allows for controllable pressure on the construction surface, overcoming the problem of uneven force during manual operation. The coating uniformity is superior to that of traditional manual roller coating.

[0020] Meanwhile, the elastic telescopic components and inclined surface design of the rolling adjustment mechanism can adapt to ground unevenness, and the rolling intensity can be adjusted by changing the position of the adjustment seat, providing the function of adjusting the rolling intensity, and taking into account both automation and operational flexibility.

[0021] Therefore, this invention solves the three core problems of low efficiency, poor uniformity, and high labor intensity in the roller application of waterproof coatings through mechanized and coordinated design. It is both innovative and practical, and is especially suitable for large-scale standardized construction of building waterproofing projects. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1: This example aims to provide a roller-brush type waterproof coating application device, mainly used for the roller coating application of waterproof coatings. In traditional roller coating application, the force, amplitude, and speed of the roller brush rely entirely on the worker's experience, lacking quantitative control methods. Different workers exhibit significant differences in operation, resulting in inconsistent construction quality in different areas of the same project, posing a great challenge to project quality control. Therefore, current waterproof coating roller coating applications are difficult, labor-intensive, and the rolling force is hard to control, resulting in poor coating uniformity and low rolling efficiency. Based on this, this example provides a roller-brush type waterproof coating application device.

[0025] like Figure 1-3 As shown, a roller-type waterproof coating application device includes a frame 1, a material spreading mechanism 3, a roller brush mechanism 4, and a drive mechanism 5. In implementation, the bottom of the frame 1 is provided with a movable wheel 2. The function of the movable wheel 2 is to enable the frame 1 to move. In implementation, the movable wheel 2 can be an electric drive wheel or a towed movable wheel 2. This embodiment takes the towed movable wheel 2 as an example for explanation. Its front side is equipped with a walking mechanism, which drives the frame 1 forward.

[0026] like Figure 6-7 As shown, the material distribution mechanism 3 is located on the front side of the frame 1. It includes a material bin 31, a feeding pipe 32, a central shaft 33, an inner bin 35, an outer bin 36, and a drive shaft sleeve 37. The material bin 31 is arranged on the frame 1 and is used to store waterproof coating. It can be set as a simple storage container as needed, or it can be equipped with a stirring structure inside to achieve the purpose of material supply. The specific configuration is not limited.

[0027] In this embodiment, the central axis 33 serves as the supporting foundation, and its outer hollow rigid material, such as... Figure 6 As shown, the central shaft 33 is fixed to the bottom of the frame 1 by a hanger. In practice, both ends of the central shaft 33 are fixed to the bottom of the hanger, and the upper part of the hanger is fixed to the bottom of the frame 1 for reinforcement from both sides.

[0028] The inner chamber 35 is fixed on the central shaft 33, and a discharge port is provided at its bottom. The main body of the inner chamber 35 is fixed between the lifting rods 34 and fixedly connected to the central shaft 33. The central shaft 33 not only serves as a support shaft but also as a conveying pipe. It is hollow inside and is connected to the outlet of the hopper 31 via the feeding pipe 32. A discharge port connected to the hollow cavity of the inner chamber 35 is provided on it. The outer chamber 36 is rotatably fitted on the outside of the inner chamber 35, and multiple material distribution ports 39 corresponding to the discharge ports are arranged along the circumference on its outside. As the outer chamber 36 rotates, the material distribution ports correspond to the discharge ports and realize the material distribution action. Finally, in this embodiment, the waterproof coating is distributed in an array of dots on the construction surface.

[0029] In this embodiment, both ends of the spindle 33 are fixed to the bottom of the frame 1 via hangers 34. The outer chamber 36 is fitted onto the outside of the inner chamber 35. The drive shaft sleeve 37 is fixed to the outside of the outer chamber 36 and is rotatably connected to the central shaft 33 via bearings. A driven wheel is provided at the end of the drive shaft sleeve 37. To facilitate material guidance, a guide platform is provided on the inner wall of the inner chamber 35. The middle part of the inner chamber 35 is fixed to the central shaft 33 via a support rod. In order to drive the outer compartment 36, in this embodiment, the drive bushing 37 is fixed to the side of the outer compartment 36 and rotatedly mounted on the central shaft 33. When passing through, the drive bushing 37 rotates, which can drive the outer compartment 36 to rotate around the inner compartment 35.

[0030] The roller brush mechanism 4 includes a sliding seat 42, a roller brush frame 41, and a roller brush 43. The sliding seat 42 is fixed to the bottom of the frame 1. A groove is horizontally provided on the upper edge of the sliding seat 42. The upper part of the roller brush frame 41 is slidably disposed in the groove via a sliding rod 44. The roller brush 43 is rotatably disposed on the roller brush frame 41. In a specific implementation, two sets of sliding seats 42 are provided, located on both sides of the frame 1 respectively. Corresponding grooves are provided on them. The square-structured sliding rod 44 is fitted into the groove and can slide along the groove. Limiting plates 45 are provided at both ends of the sliding rod to prevent it from falling out of the groove, providing a limiting basis for realizing the horizontal reciprocating motion of the roller brush frame 41.

[0031] To drive the roller brush mechanism 4 and the outer chamber 36 to rotate, this embodiment provides a drive mechanism 5 for linkage action. Specifically, the drive mechanism 5 includes a drive shaft 51, an eccentric sleeve 54, an eccentric rod 55, a drive rod 56, and a transmission wheel 53. The drive shaft 51 is rotatably mounted on the frame 1 and is a power shaft. The drive shaft 51 is connected to a drive motor 59 arranged on the frame 1. The drive shaft 51 can drive the eccentric sleeve 54 and the transmission wheel 53 to rotate. Through the transmission structure, the drive shaft 51 can drive the eccentric sleeve 54 and the transmission wheel 53 to rotate. The eccentric sleeve 54 is connected to the roller brush frame 41 via the eccentric rod 55 and the drive rod 56 to form an eccentric drive structure, causing the roller brush frame 41 to reciprocate along the slide groove. The transmission wheel 53 is connected to the drive shaft sleeve 37 to drive the outer chamber 36 to rotate around the inner chamber 35.

[0032] As an example, Figure 3 As shown in the figure, in this embodiment, eccentric sleeves 54 are fixedly provided at both ends of the drive shaft 51, and eccentric rods 55 are fixed on the eccentric sleeves 54. The two ends of the drive rod 56 are hinged between the ends of the roller brush frame 41 and the eccentric rods 55 to form an eccentric drive structure. A drive wheel 52 is provided in the middle of the drive shaft 51. The drive wheel 52 is connected to the drive motor 59 via a belt. A transmission wheel 53 is provided between the eccentric sleeve 54 and the drive wheel 52. The transmission wheel 53 is connected to the driven wheel provided on the drive shaft sleeve 37 via a belt.

[0033] In use, this embodiment adds the pre-mixed waterproof coating to the hopper 31. The waterproof coating enters the central pipe through the feeding pipe 32 and enters the inner hopper 35 from the discharge port at the bottom of the central pipe. As the outer hopper 36 is driven, when the distribution port aligns with the discharge port, the coating flows out from the distribution port and is distributed on the construction surface, forming distribution points 8. Subsequently, the rear roller brush 43 reciprocates to brush the coating distributed on the construction surface. In the specific transmission structure, this embodiment uses a motor to drive the drive shaft 51 to rotate. The rotation of the drive shaft 51 drives the eccentric rollers on both sides. When sleeve 54 rotates, the eccentric sleeve 54 causes the eccentric rod 55 to swing, which in turn drives the roller brush frame 41 to perform eccentric reciprocating motion via the drive rod 56. This enables the roller brush roller 43 to perform roller coating on the construction surface in a reciprocating manner. At the same time, the transmission wheel 53 rotates on its own and drives the drive shaft sleeve 37 to rotate via a belt. The wheel diameter is configured to achieve the corresponding ratio of the reciprocating roller brush and the material distribution interval, ensuring that the roller coating speed matches the amount of waterproof coating. The device achieves a balanced roller coating speed and precise control of the coating output, greatly improving the controllability and precision of the waterproof coating roller coating operation.

[0034] Example 2: This example further provides a driving mechanism 5.

[0035] like Figure 4-5 As shown in the figure, in this embodiment, the drive shaft 51 is connected to the follower shaft 58 via a belt or gear drive. The two ends of the follower shaft 58 are provided with eccentric sleeves 54, and eccentric rods 55 are fixed on the eccentric sleeves 54. The two ends of the drive rod 56 are hinged between the ends of the roller brush frame 41 and the eccentric rods 55, forming an eccentric drive structure. The drive wheel and the transmission wheel 53 are fixed at the two ends of the drive shaft 51 respectively. The drive wheel 52 is connected to the drive motor 59 via a belt, and the transmission wheel 53 is connected to the driven wheel provided on the drive shaft sleeve 37 via a belt. The follower shaft and the drive shaft 51 are both rotatably mounted on the frame 1 via a fixed seat.

[0036] In this embodiment, the follower shaft is used as the power output shaft of the eccentric drive structure. A corresponding eccentric sleeve 54 is configured at its end, which can be adjusted according to the arrangement position of the brush roller 43 to adapt to the position of the brush roller 43. Through end transmission, interference with the movement of the eccentric rod 55 and the drive rod 56 is avoided. The structure is precisely designed, and the transmission relationship between the drive shaft 51 and the reciprocating motion is further realized through the belt transmission ratio.

[0037] Example 3: This example also includes a roller adjustment mechanism 6. For different construction road surfaces, people often want to achieve different roller thicknesses. In order to achieve different roller thicknesses, this example configures the adjustment frame with an inclined structure, which facilitates the application of downward force and provides a basis for roller thickness adjustment.

[0038] In specific implementation, such as Figure 8-9As shown, the roller brush adjustment mechanism 6 includes an adjustment seat 62, an adjustment frame 61, and an elastic telescopic component 64. The rear side of the roller brush frame 41 is a forward-inclined slope. The adjustment seat 62 is fixed to the frame 1 and has a horizontal adjustment groove. The adjustment frame 61 has a mounting surface parallel to the slope. The two ends of the elastic telescopic component 64 are hinged between the slope and the mounting surface. The roller brush frame 41 includes a frame body, an adjustment rod 411, and an adjustment sleeve 412. The adjustment rod 411 is mounted on the frame body and is slidably fitted into the adjustment sleeve 412. A spring is provided between the two, causing the adjustment rod to always extend outward. The upper part of the adjustment sleeve 412 is fixedly connected to a sliding rod. The drive rod 56 is connected to the adjustment sleeve and realizes reciprocating translational movement. The adjustment rod structure provides a margin of movement, and the elastic telescopic component 64 provides pressure intensity adjustment. The two work together to adjust the roller brush intensity. Specifically, the structure of the elastic telescopic component 64 can be a linear elastic telescopic rod or a spring structure.

[0039] The adjustment frame is adjustablely fixed in the adjustment groove by the adjustment block. In this embodiment, the adjustment block is slidably set in the adjustment groove and can be tightened by bolts on both sides to adjust the position of the adjustment frame, thereby changing the downward force provided by the elastic telescopic component to the roller brush frame and realizing the adjustment of the roller brush thickness.

[0040] In another embodiment, a dovetail-shaped groove 65 is provided on the inclined surface, one end of the elastic telescopic component 64 is fixed on the mounting surface, and the other end is slidably disposed in the groove by the slider 66.

[0041] With the above structure, this embodiment can provide a corresponding downward force to the roller brush 43 according to the oscillation progress, thereby adjusting the roller brush force and controlling the thickness of the roller brush. In addition, the structure in this embodiment can also adapt to uneven construction surfaces and change accordingly with the height of the construction surface.

[0042] Example 4 further illustrates the structure of the roller brush 43.

[0043] In this embodiment, the roller brush 43 includes a front roller 431 and a rear roller 432, both of which are rotatably mounted on the roller brush frame 41. The rear roller 432 includes multiple roller units 4321, which are connected by a connecting shaft 4322. Each roller unit corresponds to a fabric inlet. This structure enables the corresponding roller brushing of the waterproof coating, improving the brushing effect.

[0044] In this embodiment, as shown Figure 10As shown, a clearance groove 21 can be arranged on the rear moving wheel 2 to avoid the paint spot; a heating module or a drying module 7 can be configured on the roller brush frame 41 as needed to provide the required conditions, such as temperature and drying conditions, during the waterproof coating application process according to the characteristics of the waterproof coating.

[0045] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is to achieve automatic dotted distribution of paint by means of the cooperation between the rotating outer chamber and the fixed inner chamber of the cloth-laying mechanism, and to perform the brushing operation by means of a reciprocating roller brush. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
