Description

Technical Field

[0001] This utility model relates to the technical field of coating production, and more specifically, it relates to a filling and sealing device for coating production. Background Technology

[0002] In the paint production process, filling and sealing are key steps to ensure product quality and achieve mass production. Hydraulic filling and sealing equipment for paint production significantly improves production efficiency through integrated filling and sealing operations, and has become the core equipment of automated production lines for paint companies. In the current mainstream hydraulic filling and sealing equipment, the operating platform provides stable support during production, and multiple placement slots are opened on the top of the placement plate to support the paint tanks. The filling mechanism injects a quantitative amount of paint into the tank, and the sealing mechanism performs hydraulic sealing on the filled tank. The overall process is adapted to the needs of continuous and large-scale paint production.

[0003] An existing hydraulic sealing equipment for paint production has been found to have the following issues during use: 1. The existing tank fixing mechanism in the equipment placement tank mostly adopts the bolt clamping mode. This fixing method requires the staff to make multiple adjustments, which cannot achieve quick fixing of the tank, thus resulting in poor practicality.

[0004] 2. The rotation drive of the placement plate relies on a motor, which drives the placement plate to rotate through a transmission component, realizing the switching of the tank between the filling mechanism and the capping mechanism. However, the existing drive motor cannot be disassembled quickly, which requires a lot of working time, resulting in poor practicality. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a filling hydraulic sealing device for paint production, so as to solve the technical problems mentioned in the background art, such as the cumbersome operation of the placement tank fixing mechanism and the difficulty in disassembling the motor that drives the placement plate to rotate.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a filling and sealing hydraulic device for paint production, comprising an operating table, a placement plate rotatably mounted on the top of the operating table, four sets of placement slots on the top of the placement plate, a filling mechanism at the rear end of the top of the operating table, a capping mechanism at the right end of the top of the operating table, an annular block at the bottom of the placement plate, toothed blocks evenly distributed at the bottom of the annular block, an adjusting component at the front end of the top of the operating table, and a mounting plate slidably connected to the front end of the top of the operating table via the adjusting component, the top of the mounting plate being provided with... The connecting assembly includes a servo motor mounted on the top of the mounting plate via the connecting assembly. A connecting shaft is located at the rear output end of the servo motor. A cross groove is located at the rear end of the connecting shaft, and a cross block is tightly fitted inside the cross groove. A rotating rod is located at the rear end of the cross block. A mounting block is located at the front end of the top of the operating table, and the mounting block has a reserved hole. The outer side of the rotating rod is rotatably connected to the reserved hole of the mounting block. A connecting gear is located at the rear end of the outer side of the rotating rod, and the top of the connecting gear meshes with the gear block. Fixing components are installed in all four sets of placement slots.

[0007] The present invention is further configured such that the fixing component includes two sets of arc-shaped clamps, the bottom of the placement groove is provided with a sliding groove, a sliding rod is fixedly installed in the sliding groove of the placement groove, and connecting blocks are fitted on both ends of the outer side of the sliding rod. The bottoms of the two sets of connecting blocks are slidably connected to the sliding groove of the placement groove, and the tops of the two sets of connecting blocks are provided with arc-shaped clamps. Connecting springs are fitted on both ends of the outer side of the sliding rod, and the left and right ends of the two sets of connecting springs are evenly connected to one end of the corresponding connecting block and one end of the sliding groove of the placement groove. The cooperation of the connecting springs with the sliding rod and connecting blocks realizes the automated clamping of the tank when it is placed in and when it is removed, without the need for manual adjustment by the staff, which greatly improves the tank clamping efficiency. The arc-shaped structure of the arc-shaped clamps can be adapted to paint tanks of different diameters, and the elastic deformation of the connecting springs can automatically adjust the clamping force to avoid unstable fixing or tank deformation due to differences in tank specifications, thereby enhancing the adaptability of the equipment to tanks of multiple specifications.

[0008] The present invention is further configured such that the adjusting component includes a connecting screw, a sliding groove is provided at the front end of the top of the operating table, the connecting screw is rotatably disposed in the sliding groove of the operating table, a slider is threadedly connected to the outer side of the connecting screw, and the bottom of the slider is slidably connected to the sliding groove of the operating table, and the top of the slider is connected to the bottom of the mounting plate; this allows the mounting plate position adjustment to be performed without the need for tools, and the operator can operate it with one hand. The sliding cooperation between the slider and the sliding groove of the operating table provides precise guidance for the movement of the mounting plate, ensuring that the servo motor does not deviate during movement. The self-locking characteristic of the threaded transmission allows the mounting plate to remain stably stationary after adjustment, without the need for an additional locking structure, ensuring that the position of the servo motor does not loosen during operation and guaranteeing transmission stability.

[0009] The present invention is further configured such that the connecting assembly includes two sets of positioning screws, a mounting base is provided on the outside of the servo motor, the bottom of the mounting base is in close contact with the top of the mounting plate, and fixing blocks are provided on both the left and right sides of the mounting plate. Both sets of fixing blocks and the mounting plate are provided with threaded holes through them. The two sets of positioning screws are threadedly connected to the fixing blocks and the mounting plate through the threaded holes respectively. This significantly shortens the disassembly time and improves maintenance efficiency. The threaded connection between the positioning screws and the threaded holes has good fastening properties, which can effectively resist the vibration of the servo motor during operation and prevent the motor from loosening. At the same time, the threaded connection facilitates subsequent disassembly.

[0010] The present invention is further configured such that a guide ramp is provided at the top of the arc-shaped clamping plate to guide the tank into the slot accurately, reducing the need for workers to adjust the positioning of the tank and improving the filling efficiency. The guide ramp moves synchronously with the arc-shaped clamping plate, without affecting the clamping function of the fixing components. Moreover, the structure is simple and does not require additional power to drive it. The guiding function can be achieved solely through the mechanical structure.

[0011] The present invention is further provided with an anti-slip pad at one end of the clamping surface of the arc-shaped clamping plate; the high friction characteristics of the anti-slip pad effectively solve the problem of easy slippage of the tank after clamping in existing equipment, and the elastic material of the anti-slip pad can adapt to the slight unevenness on the outside of the tank, ensuring that the clamping surface is fully in contact, further enhancing the fixing effect, while avoiding the squeezing deformation of the tank caused by rigid clamping.

[0012] The present invention is further configured such that the front end of the connecting screw passes through the slide groove of the operating table and is provided with a rotating handle, and the top of both sets of positioning screws is provided with a rotating handle; this increases the force application radius, so that the operator can rotate the connecting screw or the positioning screw without applying excessive force.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a filling and sealing device for paint production, which has the following advantages: 1. Automatic clamping and fixing of the can is achieved through a fixed component, eliminating the need for manual adjustment by staff, significantly reducing can clamping time and improving batch operation efficiency. The servo motor drives the placement plate to rotate stably through the transmission link of the connecting shaft, cross block, rotating rod and connecting gear, ensuring that the can is accurately switched to the filling and capping station, avoiding paint spillage or misalignment of the seal due to station misalignment, and improving the product qualification rate. The tight clamping design of the cross block and the cross slot of the connecting shaft not only ensures stable power transmission, but also provides convenient disassembly of the servo motor. During subsequent maintenance, the cross block and slot can be directly separated without disassembling the entire transmission component, solving the problem of difficult disassembly of existing motors.

[0019] Please see Figure 1-5A hydraulic filling and sealing device for paint production includes an operating table 1, a placement plate 2 rotatably mounted on the top of the operating table 1, four sets of placement slots 3 on the top of the placement plate 2, a filling mechanism 4 at the rear end of the top of the operating table 1, a capping mechanism 5 at the right end of the top of the operating table 1, an annular block 6 at the bottom of the placement plate 2, toothed blocks 7 evenly distributed at the bottom of the annular block 6, an adjusting component at the front end of the top of the operating table 1, and a mounting plate 8 slidably connected to the front end of the top of the operating table 1 via the adjusting component. A connecting component is mounted on the top of the mounting plate 8, and the top of the mounting plate 8 is connected to the connecting component. A servo motor 9 is provided, and a connecting shaft 10 is provided at the output end of the servo motor 9. A cross groove is provided at the rear end of the connecting shaft 10. A cross block 11 is tightly fitted in the cross groove of the connecting shaft 10. A rotating rod 12 is provided at the rear end of the cross block 11. A mounting block 13 is provided at the front end of the top of the operating table 1. The mounting block 13 is provided with a reserved hole, and the outer side of the rotating rod 12 is rotatably connected to the reserved hole of the mounting block 13. A connecting gear 14 is provided at the rear end of the outer side of the rotating rod 12. The top of the connecting gear 14 is meshed with the tooth block 7. Fixing components are provided in all four sets of placement slots 3.

[0020] In this embodiment, when performing the paint filling and sealing operation, the paint cans to be filled are first placed into the four sets of placement slots 3 on the top of the placement plate 2. The fixing components in the placement slots 3 automatically clamp and fix the cans. The servo motor 9 on the top of the mounting plate 8 is started. The output end of the servo motor 9 drives the connecting shaft 10 to rotate. The cross block 11 tightly fitted in the cross slot at the rear end of the connecting shaft 10 rotates synchronously with the connecting shaft 10. The cross block 11 drives the rotating rod 12 at the rear end to rotate. The outer side of the rotating rod 12 is rotatably connected to the reserved hole of the mounting block 13 at the front end of the top of the operating table 1, ensuring that the rotating rod 12 rotates stably. The connecting gear 14 at the rear end of the outer side of the rotating rod 12 rotates with the rotating rod 12. The top of the connecting gear 14 meshes with the tooth block 7 of the ring block 6 at the bottom of the placement plate 2, thereby driving the ring block 6 and the placement plate 2 to rotate along the top of the operating table 1.

[0021] Control the speed of the servo motor 9 so that the placement plate 2 drives the tank to rotate sequentially to the bottom of the filling mechanism 4 at the rear end of the top of the operating platform 1. The filling mechanism 4 injects a fixed amount of paint into the tank. After filling is completed, the placement plate 2 continues to rotate, transporting the filled tank to the bottom of the capping mechanism 5 at the top right end of the operating platform 1. The capping mechanism 5 performs hydraulic sealing on the tank. After sealing is completed, the placement plate 2 rotates to the initial pick-up position and then the tank can be taken out.

[0022] More specifically, when the paint can is placed into the placement groove 3, the bottom of the can first contacts the two sets of arc-shaped clamps 15. As the can moves downward, the outer side of the can press against the arc-shaped clamps 15, and the arc-shaped clamps 15 drive the connecting block 17 at the top to slide along the slide rod 16 in the bottom groove of the placement groove 3. The two sets of connecting blocks 17 move towards both ends of the slide rod 16 respectively, synchronously compressing the connecting springs 18 fitted at both ends of the outer side of the slide rod 16. The connecting springs 18 generate elastic deformation, forming a reverse clamping force. When the can is completely placed into the placement groove 3, the downward movement of the can stops, the connecting springs 18 rebound, pushing the connecting blocks 17 to move along the slide rod 16 towards the can, causing the arc-shaped clamps 15 to fit tightly against the outer side of the can, thus achieving the clamping and fixing of the can.

[0023] Please see Figure 1 and Figure 4 As one embodiment of the adjustment component: the adjustment component includes a connecting screw 19, a slide groove is provided at the front end of the top of the operating table 1, the connecting screw 19 is rotatably provided in the slide groove of the operating table 1, a slider 20 is threadedly connected to the outside of the connecting screw 19, and the bottom of the slider 20 is slidably connected to the slide groove of the operating table 1, and the top of the slider 20 is connected to the bottom of the mounting plate 8.

[0024] Specifically, the operator rotates the connecting screw 19, causing the slider 20, which is threaded on the outer side of the connecting screw 19, to slide along the slide groove of the operating table 1 as the screw rotates. The top of the slider 20 is fixedly connected to the bottom of the mounting plate 8, thereby driving the mounting plate 8 to slide synchronously. The servo motor 9 at the top of the mounting plate 8 moves with the mounting plate 8, causing the mounting plate 8 to slide away from the mounting block 13, so that the cross block 11 disengages from the cross slot of the connecting shaft 10. Then, the servo motor 9 can be disassembled through the connecting assembly.

[0025] Please refer to Figures 2-4 As a further embodiment of the connecting component: the connecting component includes two sets of positioning screws 21, a mounting base 22 is provided on the outside of the servo motor 9, the bottom of the mounting base 22 is in close contact with the top of the mounting plate 8, and fixing blocks 23 are provided on both the left and right sides of the mounting plate 8. Both sets of fixing blocks 23 and the mounting plate 8 are provided with threaded holes through them, and the two sets of positioning screws 21 are threadedly connected to the fixing blocks 23 and the mounting plate 8 through the threaded holes respectively.

[0026] Specifically, the operator rotates the two sets of positioning screws 21, causing the positioning screws 21 to rotate along the threaded holes of the fixing block 23 and the mounting plate 8 until the positioning screws 21 are completely disengaged from the threaded holes. At this time, the mounting base 22 on the outside of the servo motor 9 loses the fixed constraint of the positioning screws 21, and the bottom of the mounting base 22 is separated from the top of the mounting plate 8. The servo motor 9 can then be directly removed upwards for repair or replacement.

[0027] In summary, the overall equipment is in use (or running): The paint can to be filled is placed into the four sets of placement slots 3 on the top of the placement plate 2. The can is pressed against the two sets of arc-shaped clamps 15 by the guide inclined plate 24, which drives the connecting block 17 to slide along the slide rod 16 in the slide groove of the placement slot 3, compressing the connecting spring 18 on the outside of the slide rod 16. The connecting spring 18 rebounds and pushes the connecting block 17 and the arc-shaped clamps 15 until one end of the anti-slip pad 25 is tightly attached to the can, thus completing the fixation.

[0028] Hold the rotating handle 26 at the front end of the connecting screw 19 and rotate it to drive the connecting screw 19 to rotate along the slide groove of the operating table 1. The slider 20 drives the mounting plate 8 to move, so that the connecting shaft 10 of the servo motor 9 is tightly engaged with the cross block 11. Start the servo motor 9, and the output end drives the connecting shaft 10 to rotate. The cross block 11 drives the rotating rod 12 to rotate along the reserved hole of the mounting block 13. The connecting gear 14 on the outside of the rotating rod 12 meshes with the tooth block 7 of the ring block 6 at the bottom of the placement plate 2, driving the placement plate 2 to rotate.

[0029] The placement plate 2 rotates the tank to a position below the filling mechanism 4 at the top rear end of the operating platform 1, where the filling mechanism 4 injects the paint. Then, it rotates to a position below the capping mechanism 5 on the right end, where the capping mechanism 5 hydraulically seals the tank. After sealing, the placement plate 2 returns to its original position, and the tank is lifted to compress the connecting spring 18 using the arc-shaped clamping plate 15, allowing the tank to be removed.

[0030] When the servo motor 9 needs to be disassembled, the operator rotates the connecting screw 19 by rotating the handle 26, causing the slider 20 connected to the outer thread of the connecting screw 19 to slide along the slide groove of the operating table 1 as the screw rotates. The top of the slider 20 is fixedly connected to the bottom of the mounting plate 8, thereby driving the mounting plate 8 to slide synchronously. The servo motor 9 on the top of the mounting plate 8 moves with the mounting plate 8, causing the mounting plate 8 to slide away from the mounting block 13, so that the cross block 11 disengages from the cross slot of the connecting shaft 10. Then, the operator rotates the two sets of positioning screws 21 by rotating the handle 26, causing the positioning screws 21 to rotate along the threaded holes of the fixing block 23 and the mounting plate 8 until the positioning screws 21 are completely disengaged from the threaded holes, thus completing the disassembly of the servo motor 9.

[0031] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
