Description

Technical Field

[0001] This application belongs to the field of roller spraying, specifically, it relates to a roller spraying mechanism and device. Background Technology

[0002] When painting rollers (especially cage-type steel rebar rollers), considering the wide variety of roller types, sizes, and weights, manual painting is generally used, requiring the rollers to be rotated during the painting process. Specifically, two main manual painting methods are currently employed: one involves suspending the roller using a hoist and having a worker repeatedly spray paint back and forth with a handheld spray gun until the desired finish is achieved; the other involves immersion, where the roller is suspended in a container filled with paint, tumbled / immersed for a period, and then removed and dried. However, due to the weight of the rollers, manual rotation is time-consuming, labor-intensive, and inefficient. Furthermore, there are issues such as uncovered paint-blind spots, safety hazards, and paint evaporation. Summary of the Invention

[0004] To achieve the above objectives, this application provides a roller painting mechanism, comprising: a receiving frame assembly including end supports arranged laterally at intervals to support the ends of rollers; the end supports including a fixed support, a movable support, and a swaying drive mechanism; the bottom end of the movable support is hinged to the fixed support and the top end is used to support the roller to be painted; the swaying drive mechanism is used to drive the movable support to sway to a central painting position, a receiving sway position to one side, or a discharging sway position to the other side; a pressing assembly disposed above the movable support and used to press the positioning roller downwards at the central painting position; and a spraying assembly disposed above the receiving frame assembly and used to spray the roller.

[0005] In some implementations, the movable support is a Y-shaped support.

[0006] In some embodiments, a rotating slide roller is laid on the top surface of the movable support, and at the central painting position, the rotating slide roller drives the drum to rotate.

[0009] In some embodiments, the spraying assembly includes: a guide rail assembly; a movable slider mounted on the guide rail assembly and capable of moving laterally and longitudinally; and a spray head rotatably mounted on the movable slider.

[0010] In some embodiments, the roller painting mechanism includes a protective cover that covers the painting assembly.

[0011] A second aspect of this application provides a roller painting apparatus, which includes the roller painting mechanism described above.

[0012] In some embodiments, the roller painting apparatus includes a feeding mechanism and a discharging mechanism with identical structures, which are arranged at both ends of the longitudinal direction of the roller painting mechanism; wherein, both the feeding mechanism and the discharging mechanism include a bottom frame and chain drive mechanisms arranged on both sides of the top of the bottom frame, the chain drive mechanism including a baffle chain with baffles spaced apart on the chain, and the two ends of the roller are used to support the chain drive mechanisms on both sides of the transverse direction and are located between adjacent baffles on the baffle chain.

[0016] In the roller painting mechanism according to this application, by controlling the sway of the movable bracket, it is possible to receive material from the receiving sway position, perform painting operations at the central painting position, and discharge material from the discharging sway position, thereby realizing the function of connecting and sending the roller to the painting station.

[0043] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0044] The roller painting mechanism and roller painting apparatus according to this application are described below with reference to the accompanying drawings.

[0045] This application discloses a novel roller spraying mechanism 100. For example... Figures 1 to 4 As shown, in one specific embodiment, the roller painting mechanism 100 includes:

[0046] The receiving frame assembly 110 includes end supports arranged laterally to support the ends of the rollers. The end supports include a fixed support 113, a movable support 114, and a swing drive mechanism 115. The bottom end of the movable support 114 is hinged to the fixed support 113 and the top end is used to support the rollers to be sprayed. The swing drive mechanism 115 is used to drive the movable support 114 to swing and can maintain it in the centered spraying position, the receiving swing position to one side, and the discharging swing position to the other side.

[0047] The clamping assembly 120 is positioned above the movable bracket 114 and is used to press the positioning roller downwards at the centered painting position; and

[0048] The spraying assembly 130 is disposed above the receiving frame assembly 110 and is used for spraying the roller.

[0049] In the roller painting mechanism 100 of this embodiment, see... Figure 1 , Figure 4 The movable bracket 114 can be driven to swing left and right by the swing drive mechanism 115, for example in... Figure 4 The roller can be swung to the left to the receiving position for receiving material. Similarly, the movable bracket 114 can be driven back to the centered painting position via the sway drive mechanism 115. After the clamping component 120 presses down on the positioning roller, the roller can be driven to rotate while the painting operation is performed by the spraying component 130. After painting is completed, the movable bracket 114 can be swung to the right to the discharge position for discharging material, thus realizing the function of connecting and discharging the roller to and from the painting station.

[0050] As can be seen, unlike the fixed bracket, the movable bracket 114 can swing left and right, which allows for better connection of the receiving frame assembly 110 to the loading roller assembly line (e.g., Figure 5 As shown, this enables assembly line operations, improving the automation level of roller conveying and spraying, and especially enhancing operational efficiency. Given that the driving force required for the swing of the movable support is not large, the swing drive mechanism 115 in this embodiment uses a cylinder. However, those skilled in the art will understand that the swing drive mechanism 115 can also be an electric cylinder, a hydraulic cylinder, or even a gear mechanism that enables the swinging engagement between the movable support 114 and the fixed support 113. These structural forms should also fall within the scope of protection of this application.

[0051] like Figure 3 and Figure 4As shown, the movable support 114 in this embodiment is a Y-shaped support. Due to the V-shaped groove design of the Y-shaped support, the Y-shaped support in the material receiving tilt position can receive the roller entering the roller painting mechanism 100 from upstream. Furthermore, a downward slope is formed on the Y-shaped support, which helps the roller slide down the slope until it reaches the center of the V-shaped groove. When the movable support 114 tilts back to the centered painting position, the roller can be stably placed in the center of the V-shaped groove. Of course, the movable support 114 can also be designed as a T-shape or other shapes.

[0052] like Figure 1 , Figure 3 and Figure 4 As shown, a rotating roller 140 is mounted on the top surface of the movable support 114. At the central spraying position, the rotating roller 140 drives the drum to rotate. When the nozzle 133 in the spraying assembly 130 sprays, the surface of the rotating drum achieves a better coating effect compared to a fixed drum. Figure 4 In the top surface of the movable support 114 shown, the rotating roller 140 can not only be arranged near the center of the V-shaped groove, but also completely cover the top surface of the movable support 114 to assist the roller in sliding on the top surface. Optionally, the rotating roller 140 can be connected to a motor via a belt. When the movable support 114 is held in the centered painting position, the motor starts, and the motor can drive the rotating roller 140 to make the roller rotate.

[0053] Meanwhile, the clamping assembly 120 can constrain the roller. In this embodiment, the clamping assembly 120 adopts a rod cylinder. When the rod of the rod cylinder extends, the rod can press down on the roller. Through the pressing of the rod and the support of the movable bracket 114, the end of the roller is constrained, thereby realizing the positioning of the roller in the spraying station and increasing the contact pressure between the end of the roller and the rotating slide roller 140, thereby increasing the friction between the end of the roller and the rotating slide roller 140, and then driving the roller to rotate by the increased friction.

[0054] like Figure 1 and Figure 3 As shown, the bottom end of the clamping assembly 120 in this embodiment is also provided with a universal ball 121 for pressing against the end of the roller. The universal ball 121 is used to press against the roller, thereby reducing the sliding friction between the clamping assembly 120 and the roller while positioning the roller, and reducing the resistance to the roller's rotation. Of course, the universal ball 121 structure can also be a caster wheel structure, with the caster pressing against the roller and positioning the roller by the caster wheel. Those skilled in the art will understand that this application is not limited to this, and the bottom end of the clamping assembly 120 may not have a rolling part and may directly contact the roller, or the rod end may be provided with a smooth coating to reduce sliding friction, etc.

[0055] In this embodiment, such as Figure 1As shown, the receiving frame assembly 110 includes: a base frame 116, at least one side of the top of the base frame 116 is provided with a slide rail 117 extending laterally toward the other side, and a sliding module 118 slidably disposed on the slide rail 117; a first end bracket 111 and a second end bracket 112 are respectively installed on the lateral sides of the top of the base frame 116, and at least one of the first end bracket 111 and the second end bracket 112 is installed on the sliding module 118.

[0056] like Figure 1 As shown, the first end bracket 111 is mounted on the sliding module 118, and the second end bracket 112 is fixedly mounted, thereby adjusting the distance between the movable brackets 114 on both sides to adapt to rollers of different specifications. Of course, those skilled in the art will understand that the second end bracket 112 can also be mounted on the sliding module 118 extending toward the first end bracket 111, or the first end bracket 111 can also be fixedly mounted.

[0057] In this embodiment, the end supports on both sides of the transverse direction are connected by a lead screw, which serves as a guide and drive. Furthermore, the slide rail 117 can be designed as a dovetail groove to prevent derailment. When the lead screw connecting the first end support 111 and the second end support 112 is adjusted, the distance between the first end support 111 and the second end support 112 changes with the length of the lead screw, thus adapting to the assembly of rollers of corresponding specifications. Of course, the slide rail 117 can be configured as a guide rod, and correspondingly, the sliding module 118 can be configured as a guide sleeve, with at least one of the first end support 111 and the second end support 112 mounted on the guide sleeve.

[0058] In this embodiment, such as Figure 1 , Figure 2 as well as Figure 4 As shown, the spraying assembly 130 includes: a guide rail assembly 131, a movable slider 132 mounted on the guide rail assembly 131 and capable of moving laterally and longitudinally, and a spray head 133 rotatably mounted on the movable slider 132. Therefore, the spray head 133 can not only follow the movable slider 132 to move longitudinally and laterally on the moving plane, but also rotate for spraying operations, making the spraying operation flexible and convenient.

[0059] The spraying assembly 130 can have various structural forms. Figure 1In the illustrated embodiment, as an example, the guide rail assembly 131 includes a mounting block arranged above the roller and also extending laterally, a pen-shaped cylinder for driving the mounting block to reciprocate longitudinally, a first guide rail laterally mounted below the mounting block, and a second guide rail fixed longitudinally. The movable slider 132 is slidably engaged with the first guide rail, and the second guide rail is slidably connected to the top of the mounting block, serving to maintain the mounting block's stable longitudinal movement. Because the movable slider 132 is slidably engaged with the laterally mounted first guide rail, the movable slider 132 can move laterally. When the pen-shaped cylinder drives the mounting block to move longitudinally, the first guide rail and the movable slider 132 mounted on the first guide rail also move longitudinally, thus achieving planar motion of the movable slider 132; simultaneously, as... Figure 2 As shown, in this embodiment, the nozzle 133 is mounted on the corner cylinder on the left side of the nozzle 133. The nozzle 133 is driven by the corner cylinder, so that it can rotate in the vertical plane.

[0060] As can be seen, the nozzle 133 can achieve multi-degree-of-freedom movement, further enhancing the spraying effect. In comparison, the efficiency of manual spraying using existing technologies is low, and for materials such as cage-type steel rollers, there are often blind spots that cannot be reached. The multi-degree-of-freedom nozzle 133 of this embodiment can achieve better coverage. Compared to immersion painting, which results in uneven paint thickness, wastes a large amount of paint, consumes a lot of paint, and exhibits paint dripping, leading to an unattractive surface finish, the multi-degree-of-freedom nozzle 133 can achieve better spray uniformity, and paint can be saved by controlling the amount of paint sprayed. Of course, there can be multiple nozzles 133, and the cylinder drive involved in the nozzle 133 can be replaced by an electric slide, magnetic drive, or other transmission methods.

[0061] like Figure 4 , Figure 5 As shown, the roller painting mechanism 100 in this embodiment also includes a protective cover 150. Since paint may escape during the painting process, this application specifically designs a protective cover 150, which covers the top of the spraying assembly 130. In contrast, when painting manually, the person is constantly surrounded by paint, which can affect their health. The protective cover 150 can collect the paint that escapes into the air during the painting process, while preventing spillage and improving safety.

[0062] The aforementioned roller painting mechanism 100 can be installed in, for example... Figure 5 The roller spraying device shown is designed to achieve automated spraying.

[0063] Specifically, the roller painting device includes a feeding mechanism 200 and a discharging mechanism 300 with identical structures, which are arranged at both ends of the longitudinal direction of the roller painting mechanism 100. Each feeding mechanism 200 and discharging mechanism 300 includes a bottom frame 210 and chain drive mechanisms 220 arranged on both sides of the top of the bottom frame 210. The chain drive mechanism 220 includes a baffle chain 230 with baffles spaced apart on the chain. The two ends of the roller are used to support the chain drive mechanisms 220 on both sides and are located between adjacent baffles on the baffle chain 230.

[0064] Clearly, the roller can sequentially pass through the feeding mechanism 200, the roller painting mechanism 100, and the discharging mechanism 300, achieving automated or semi-automated operation under program control, thus improving work efficiency. Specifically, to clamp and move the roller, the end of the roller can be positioned and installed via a chain drive mechanism 220, thereby driving the roller forward. Specifically, baffles are spaced along the chain of the baffle chain 230, and the end of the roller can be placed between adjacent baffles.

[0065] In this embodiment, specifically, to assist the forward movement of the roller, the feeding mechanism 200, the feeding position (i.e., the receiving tilt position) of the movable support 114, the discharging position (i.e., the discharging tilt position) of the movable support 114, and the height position of the discharging mechanism 300 are arranged sequentially from high to low. After the rollers waiting to be painted are placed on the chain of the feeding mechanism 200 by the hanger, the chain drive mechanism 220 conveys the rollers forward. The movable support 114 of the painting mechanism, pushed by the tilt drive mechanism 115, tilts to the feeding position to receive the rollers falling from the feeding mechanism 200. After painting is completed, the tilt drive mechanism 115 rotates the movable support 114 to the discharging position, and the rollers automatically fall onto the chain drive mechanism 220 of the discharging mechanism 300 due to their own weight. Comparatively, when using manual painting, due to the large mass of the rollers, manual conveying is time-consuming, labor-intensive, and inefficient. The roller painting device of this application can achieve automatic conveying, improving work efficiency.

[0066] like Figure 6 As shown, the feeding mechanism 200 and discharging mechanism 300 in this embodiment also include a guide mechanism 240 arranged on the lateral side of the top of the bottom frame 210. The guide mechanism 240 includes: a guide belt with a plurality of guide rollers 241 arranged longitudinally, the guide rollers 241 being used to abut the ends of the rollers; and an adjusting screw 242 for laterally pushing the guide belt.

[0067] Due to the guide mechanism 240, the end of the roller can move and abut against the guide roller 241 during the feeding and discharging process, thereby stabilizing the movement direction of the roller. By adjusting the lateral movement of the adjusting screw 242, the lateral spacing between the guide belts on both sides can be changed, thus providing directional guidance for the forward-moving roller and accommodating rollers of different specifications. Of course, the guide mechanism 240 may also exclude the guide roller 241, etc.

[0068] In this embodiment, such as Figure 6 As shown, the guide mechanism 240 also includes a sensor switch 232, which is disposed at the end of the feeding mechanism 200 adjacent to the roller painting mechanism 100. When the roller is conveyed to the sensor switch 232, the yaw drive mechanism 115 can be controlled to drive the movable bracket 114 into the feeding yaw position. The sensor switch 232 can be a magnetic induction switch or the like.

[0069] In this embodiment, such as Figure 7 As shown, the bottom frame 210 includes: a fixed module 211; and an adjustable module 212, mounted on the fixed module 211 and including a first mounting beam 213 and a second mounting beam 214 with adjustable lateral spacing. Chain drive mechanisms 220 are respectively mounted on the first mounting beam 213 and the second mounting beam 214. Figure 7 As shown, the adjustable module includes a guide rail and a sliding block. The guide rail is fixed to the fixed module 211 and extends laterally towards the second mounting beam 214. The guide rail and the first mounting beam 213 slide in contact with the guide rail via the sliding block. The sliding of the first mounting beam 213 adjusts the distance between the first mounting beam 213 and the second mounting beam 214.

[0070] In this embodiment, the first mounting longitudinal beam 213 and the second mounting longitudinal beam 214 are also connected by a lead screw, which serves as a guide and drive. The guide rail can be designed as a dovetail groove to prevent derailment. When the lead screw connecting the first mounting longitudinal beam 213 and the second mounting longitudinal beam 214 is adjusted, the distance between the first mounting longitudinal beam 213 and the second mounting longitudinal beam 214 changes with the length of the lead screw, thereby adapting to the assembly of rollers of corresponding specifications. Those skilled in the art will understand that this application is not limited to the dovetail groove structure described above, but can also be other structural forms such as a T-groove that can realize the lateral movement guidance of the first mounting longitudinal beam 213 or the second mounting longitudinal beam 214. Of course, the guide rail can also be set as a guide rod, and correspondingly, the sliding block is set as a guide sleeve, and at least one of the first mounting longitudinal beam 213 and the second mounting longitudinal beam 214 is mounted on the guide sleeve.

[0071] The following is in conjunction with the appendix Figure 5 The roller painting device is described in detail, along with the roller painting process.

[0072] 1. After welding and sandblasting, the rollers are placed on various stations on the chain of the feeding mechanism 200 using a lifting device. The feeding mechanism 200, which includes a host computer, then starts under its control. The baffle chain 230 conveys the rollers forward, and the guiding mechanism 240 guides the rollers to their correct position. Simultaneously, the movable support 114 of the roller painting mechanism 100, which includes a sensor, rotates to the receiving tilt position under the push of the tilting drive mechanism 115 to receive the conveyed rollers. At this point, the sensor detects the presence of rollers in the roller painting mechanism 100. Under the control of the host computer, the tilting drive mechanism 115 starts, causing the movable support 114 to rotate back to the centered painting position. The feeding mechanism 200 continues to convey rollers, stopping when the second roller reaches the position of the sensor switch 243. The host computer then determines whether the sensor of the roller painting mechanism 100 has detected a roller. If the sensor of the roller painting mechanism 100 has detected a roller, the feeding mechanism 200 stops working, and the feeding stops. After the rollers in the roller painting mechanism 100 have finished painting, the host computer starts the feeding mechanism 200. This stage is the feeding stage.

[0073] 2. After the roller enters the roller painting mechanism 100, the sensor on the roller painting mechanism 100 detects the roller and presses it through the pressing assembly 120. Then, the rotating slide roller 140 is started to drive the roller to rotate. At the same time, the spraying assembly 130 is started and the nozzle 133 moves at a constant speed along the set direction to spray paint into the inner and outer surfaces of the roller. The speed and spraying time are adjustable. The paint in the air is collected by negative pressure through the protective cover 150 containing the collection pipe to prevent spillage.

[0074] 3. After spraying, the roller is unloaded. Driven by the sway drive mechanism 115, the movable bracket 114 is rotated to the unloading sway position. With the roller's own weight and the cooperation of the guide device 240, the roller automatically falls onto the baffle chain 230 of the unloading mechanism. After unloading, if the sensor on the roller painting mechanism 100 no longer detects the roller, the feeding mechanism 200 restarts, feeding the second roller to the roller painting mechanism 100.

[0075] This completes one work cycle. Then, the second roller is fed, sprayed, unloaded, and dried. The above steps are repeated to achieve a production line operation for roller spraying.
