Description

Technical Field

[0001] This invention relates to the field of waterproof coating processing technology, specifically to a polyurethane waterproof coating processing and preparation apparatus. Background Technology

[0002] Polyurethane waterproof coatings, as a high-performance waterproof material, are widely used in construction, municipal engineering, and transportation due to their strong adhesion, good elasticity, and excellent weather resistance. One of the core processes in their production is the filling process. However, the coating itself is extremely sensitive to impurities such as moisture and dust. Production dust remaining in the can (such as metal shavings from can manufacturing and floating dust during packaging and transportation) and humid air can react with the isocyanate components in the coating, leading to abnormal curing speed, pinholes and craters on the cured surface, and even reducing the coating's bonding strength and waterproof performance, seriously affecting the stability of product quality.

[0003] For the filling process, most existing equipment lacks a dedicated internal cleaning structure or only uses simple air blowing for cleaning, which cannot effectively remove dust adhering to the inner wall of the can. Some equipment with cleaning functions requires a separate cleaning station, resulting in the separation of cleaning and filling processes, increasing the production line length and cycle time. Furthermore, during the transfer of cleaned cans to the filling station, they are prone to re-inhaling humid air and dust, posing a high risk of secondary contamination. The movement trajectories of cleaning and filling components interfere with each other, requiring manual adjustment of component positions after cleaning before filling, or additional steps to transfer cans after filling, leading to a discontinuous production process and affecting overall production efficiency.

[0004] Therefore, we propose a polyurethane waterproof coating processing and preparation device to solve the above problems. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a polyurethane waterproof coating processing and preparation apparatus. This apparatus solves the problems mentioned in the background section regarding the canning process. Existing equipment often lacks a dedicated internal cleaning structure or relies solely on simple air blowing for cleaning, failing to effectively remove dust adhering to the inner wall of the can. Furthermore, some equipment with cleaning functions requires a separate cleaning station, separating the cleaning and filling processes, increasing production line length and cycle time. Additionally, during the transfer of cleaned cans to the filling station, they are prone to re-inhaling humid air and dust, posing a high risk of secondary contamination. The movement trajectories of the cleaning and filling components interfere with each other, requiring manual adjustment of component positions after cleaning before filling, or necessitating additional steps to transfer cans after filling, resulting in a discontinuous production process and impacting overall production efficiency.

[0012] Furthermore, a push rod connecting plate is installed on the side of the electric push rod, and a support plate is reinforced to the side of the push rod connecting plate by bolts. A transfer platform for lifting and moving the paint cylinder is installed at the bottom of the support plate.

[0013] Furthermore, a control box is installed on one side of the support plate, and a cover assembly is installed on the control box away from the support plate. The bottom of the functional column is reinforced to the side of the lower end of the support plate by bolts.

[0014] Furthermore, a column through groove is provided on the lower part of the surface of the functional column, and a sliding plate is inserted into the column through groove to slide with the column through groove. The end of the sliding plate is connected to a positioning stud, and the front end of the sliding plate is fixed with a positioning insert.

[0015] Furthermore, a plate moving groove is provided on the side end of the positioning insert, and a moving adjustment rod is slidably connected in the groove. A positioning slot is provided longitudinally at the front end of the moving adjustment rod, and a positioning block is inserted longitudinally in the groove of the positioning slot. A limiting side plate is fixed on the top of the positioning block, and a guide plate is integrally formed at the front end of the limiting side plate.

[0016] Furthermore, the guide grooves are spirally distributed, and the included angle between the beginning and end of the guide grooves is 90°. The surface of the collar plate is provided with a longitudinal groove, and a positioning pin that can be combined with the connecting cross column is inserted longitudinally into the groove.

[0017] Furthermore, the base of the electric push rod 2 is fixedly provided with a base plug, and the base plug is inserted into the hole of the column through slot. The side of the functional column is provided with an array slot. The surface of the base plug is fixed with a side insertion protrusion that can be inserted into the array slot hole. The end of the base plug is connected with a front stud.

[0018] Furthermore, a closed pressure plate is reinforced to the rear end of the connecting column by bolts, and a negative pressure chamber is installed at the bottom center of the closed pressure plate. A negative pressure air groove is opened on the surface of the negative pressure chamber, and a high-pressure air nozzle is installed at the bottom of the negative pressure chamber.

[0019] Furthermore, a top assembly is installed at the top center of the closed pressure plate, and a connecting sleeve part that communicates with the high-pressure air nozzle is installed inside the top assembly. An external tooth part is installed on the outer wall of the connecting sleeve part, and a drive gear plate part is engaged on one side of the external tooth part.

[0020] Furthermore, the top of the closed pressure plate is equipped with a connecting pipe that communicates with the negative pressure air groove and the cavity inside the negative pressure chamber. The base side of the supporting plate is equipped with a negative pressure dust collection component and a high pressure air source component, and the negative pressure dust collection component and the high pressure air source component are respectively connected to the connecting pipe and the connecting sleeve through pipelines.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides a polyurethane waterproof coating processing and preparation apparatus, which has the following beneficial effects:

[0023] This invention integrates the functions of tank cleaning and paint filling into the same equipment unit through the integrated design of the functional column, collar plate and closed pressure plate. There is no need to set up an additional independent cleaning station, which shortens the production line length. The cleaning action and the filling action are linked by the mechanical structure. The cooperation of the guide longitudinal groove and the guide inclined groove realizes the rotation and lifting of the collar plate. After cleaning, filling can be carried out directly, avoiding secondary contamination during the tank transfer process, and saving the waiting time for process switching.

[0024] This invention integrates a negative pressure chamber and a rotatable high-pressure nozzle at the bottom of a closed pressure plate. A servo motor drives the connecting sleeve to rotate the high-pressure nozzle. Combined with the annularly distributed negative pressure air grooves, it forms a cleaning mode of rotary blowing + annular adsorption, which can fully cover the inner wall, bottom and corners of the tank. During the cleaning process, the closed pressure plate fits tightly with the tank opening to form a sealed space, preventing dust escape and outside air intrusion. At the same time, the high-pressure air source component provides dry and clean blowing gas, which, combined with the negative pressure dust suction component, quickly removes humid air and dust, eliminating the reaction between moisture, dust and coating at the source, and significantly reducing the incidence of quality problems such as abnormal coating curing and surface pinholes.

[0025] The inner protrusion of the inner wall of the collar plate of this invention slides in conjunction with the guide longitudinal groove and guide inclined groove of the functional column, so that the closing pressure plate can achieve a continuous action of rotation avoidance, vertical pressing, sealing and cleaning and filling: In the non-working state, the closing pressure plate rotates to the side of the transfer table without affecting the movement of the can; when working, the top pressure plate and bottom support plate are driven by the electric push rod to drive the collar plate to accurately lift and rotate, ensuring that the closing pressure plate is coaxially aligned with the can opening and avoiding collision damage.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example

[0041] like Figure 1-12 As shown in the figure, an embodiment of the present invention discloses a polyurethane waterproof coating processing and preparation device, including a coating discharge pipe 1 and an electric push rod 2 connected to the top of the coating discharge pipe 1. A push rod connecting plate 3 is installed on the side of the electric push rod 2, and a support plate 4 is bolted to the side of the push rod connecting plate 3. A transfer platform 5 for lifting and moving the coating cylinder is installed at the bottom of the support plate 4. The entire transfer platform 5 has a long coverage area, which allows the material bucket to be pushed to the next step after receiving pigment under the coating discharge pipe 1. A control box 6 is installed on one side, and a capping assembly 7 is installed on the control box 6 away from the supporting plate 4. The paint bucket, after being filled with pigment, moves on the transfer platform 5. The entire device is operated and controlled by the control box 6. It is worth noting that the way the paint bucket is moved is done manually. The paint bucket is pushed to the bottom of the capping assembly 7 by hand, and then the lid of the paint bucket is pressed on the top of the bucket. The capping assembly 7 is then used to press the lid tightly. The capping assembly 7 adopts existing conventional technology, and its working principle and composition will not be described in detail.

[0042] The difference is that the functional column part 8 is installed on one side of the paint discharge pipe 1, and a guide longitudinal groove 24 is opened near the top of the functional column part 8. A guide inclined groove 25 is connected to the top of the guide longitudinal groove 24. The guide inclined groove 25 is spirally distributed, and the included angle between the beginning and end of the guide inclined groove 25 is 90°. At the same time, the collar plate 26 is sleeved on the outside of the functional column part 8, and the inner wall of the collar plate 26 is fixed with an inner protrusion 29 that can be inserted into the guide inclined groove 25 and the guide longitudinal groove 24 and slide. Due to the special design of the guide inclined groove 25, and the fact that the collar plate 26 can move and rotate freely outside the functional column part 8, when the inner protrusion 29 moves longitudinally in the guide longitudinal groove 24, the entire collar plate 26 moves longitudinally. As the inner protrusion 29 gradually moves from the top of the guide longitudinal groove 24 into the groove of the guide inclined groove 25, the entire collar plate 26 not only moves longitudinally within a small range, but is also forced to rotate at an angle of 90°. That is, the initial position and the end position of the rotation correspond to the closed pressure plate 33 being located above the transfer table 5 and the closed pressure plate 33 being located on the side of the transfer table 5, respectively. This ensures that the closed pressure plate 33 does not affect the normal movement of the paint bucket. At the same time, since the guide longitudinal groove 24 has a certain height, when the collar plate 26 moves longitudinally in the groove of the guide longitudinal groove 24, the closed pressure plate 33 can press on the top of the paint bucket. Through this design, different paint buckets with a certain height range can be adapted.

[0043] To drive the longitudinal movement of the collar plate 26, a connecting cross post 31 is connected to the surface of the collar plate 26. A top pressure plate 27 and a bottom support plate 28 are installed on the upper and lower sides of the positioning pin 32, and the output end of an electric push rod 23 is connected to the end of the top pressure plate 27 and the bottom support plate 28. There is a gap between the upper and lower top pressure plate 27 and the bottom support plate 28 for the insertion of the connecting cross post 31. Both the top pressure plate 27 and the bottom support plate 28 are arc-shaped. Due to the connection between the collar plate 26 and the connecting cross post 31, the collar plate 26 rotates, causing the connecting cross post 31 to rotate synchronously. To ensure that the top pressure plate 27 and the bottom support plate 28 still have the ability to push the connecting cross post 31 up and down after it rotates, The top pressure plate 27 and bottom support plate 28 are designed as arc-shaped plate structures, and their length covers the rotation range of the connecting cross column 31. The electric push rod 23 is the main driving force. In actual use, the top pressure plate 27 and bottom support plate 28 are moved downward by the electric push rod 23. Since the inner protrusion 29 is at the top of the guide groove 25, when the top pressure plate 27 is pressed down, the connecting cross column 31 is moved downward, which causes the collar plate 26 to slowly move downward and rotate. Finally, the inner protrusion 29 enters the guide groove 24 and the collar plate 26 moves vertically downward. During the vertical downward process, the closed pressure plate 33 connected to the front end of the connecting cross column 31 by bolts is pressed on the top of the pigment cylinder. The closed pressure plate 33 can put the pigment cylinder in a temporary sealed state.

[0044] The bottom of the functional column 8 is reinforced to the side of the lower end of the supporting plate 4 by bolts. A column through groove 9 is formed at the lower part of the surface of the functional column 8, and a sliding plate 11 that is slidably adapted to the column through groove 9 is inserted into the column through groove 9. The end of the sliding plate 11 is connected to a positioning stud 12, and a positioning insert 10 is fixed at the front end of the sliding plate 11. A plate moving groove 13 is opened on the side end of the positioning insert 10, and a moving adjustment rod 14 is slidably connected in the groove of the plate moving groove 13. A positioning slot 15 is longitudinally opened at the front end of the moving adjustment rod 14, and a positioning block 17 is longitudinally inserted in the groove of the positioning slot 15. A limiting side plate 16 is fixed on the top of the positioning block 17, and a guide plate 18 is integrally formed at the front end of the limiting side plate 16. The guide plate 18 and the limiting side plate 16 are connected through the guide plate 18 and the limiting side plate 16. The bending design of 6 provides guidance for the initial placement of the paint tube, and the length of the limiting side plate 16 and the guide plate 18 can be customized according to actual usage requirements, not limited to the size shown in the figure. When actually placing the paint tube, the side of the paint tube should be pressed against the surface of the limiting side plate 16, and the positioning block 17 can be fully installed by inserting it vertically into the hole of the positioning slot 15. The limiting side plate 16 can be replaced. At the same time, since the top of the plate moving groove 13 is provided with a threaded hole with a bolt, the extension position of the limiting side plate 16 can be adjusted by moving the adjusting rod 14 in the groove of the plate moving groove 13. Then, the adjusting rod 14 can be tightened to limit the movement. In this way, the usage position of the limiting side plate 16 can be adjusted according to actual usage requirements.

[0045] The surface of the collar plate 26 is provided with a longitudinal groove 30. A positioning pin 32 that can be combined with the connecting cross post 31 is inserted longitudinally into the groove of the collar plate 26. The bottom of the positioning pin 32 has a threaded hole. The connection strength between the connecting cross post 31 and the collar plate 26 can be strengthened by bolts, thereby improving the stability of the connection between the closing pressure plate 33 and the collar plate 26. The base of the electric push rod 23 is fixedly provided with a base insert 19, which is inserted into the hole of the column through groove 9. The side of the functional column part 8 is provided with an array slot 20. The surface of the base insert 19 is fixedly provided with a hole that can be inserted into the array slot 20. The side insertion protrusion 21 and the end of the base insertion block 19 are connected to the front stud 22 of the insertion block. The position of the base of the electric push rod 23 can be adjusted by the longitudinal movement of the base insertion block 19 in the groove of the column through groove 9. At the same time, in order to improve the installation stability of the base of the electric push rod 23, the side insertion protrusion 21 and the array slot 20 are designed. When the base insertion block 19 is inserted into the groove of the column through groove 9, the side insertion protrusion 21 can be inserted into the array slot 20. This structure can initially limit the position of the base insertion block 19. It can be locked by the nut through the front stud 22 of the insertion block at the end of the base insertion block 19.

[0046] A negative pressure chamber 35 is installed at the bottom center of the closed pressure plate 33. A negative pressure air groove 36 is formed on the surface of the negative pressure chamber 35. A high-pressure air nozzle 37 is installed at the bottom of the negative pressure chamber 35 and can rotate freely within the negative pressure chamber 35. The negative pressure air groove 36 is annular. Airflow is ejected through the high-pressure air nozzle 37. During the process of the closed pressure plate 33 closing the pigment cylinder, any impurities that may remain in the cylinder are blown up and sucked in through the negative pressure air groove 36. There is a channel in the negative pressure chamber 35 that communicates with the negative pressure air groove 36. Through this channel, the air enters the connecting pipe 43 connected to the top of the closed pressure plate 33. A top is installed at the center of the top of the closed pressure plate 33. The kit 38 includes a connecting sleeve 39 that communicates with the high-pressure nozzle 37. The outer wall of the connecting sleeve 39 is fitted with an external tooth 40. One side of the external tooth 40 is engaged with a drive gear plate 42. The bottom of the drive gear plate 42 is equipped with a servo motor 41 that drives the drive gear plate 42 to rotate. A conventional rotary sealing structure is provided at the connection between the connecting sleeve 39 and the closed pressure plate 33. The drive gear plate 42 drives the external tooth 40 through the drive of the servo motor 41, thereby causing the connecting sleeve 39 to drive the high-pressure nozzle 37 to rotate. The rotation of the high-pressure nozzle 37 allows the airflow to more fully cover the pigment cylinder.

[0047] The base of the supporting plate 4 is equipped with a negative pressure dust collection component 44 and a high pressure air source component 45. The negative pressure dust collection component 44 and the high pressure air source component 45 are connected to the connecting pipe 43 and the connecting sleeve 39 through pipelines. The pipelines are of sufficient length, and the connecting sleeve 39 and the pipeline are connected by a sealing rotary joint to maintain sealing and connection. The high pressure air source component 45 has a built-in air source generation device, air source processing device and control execution element, while the negative pressure dust collection component 44 has a built-in vacuum generation device, filtration and collection system and control and monitoring element.

[0048] Working principle: The core working principle of this device is to achieve precise cleaning of the tank and filling operation before the polyurethane waterproof coating is filled through the coordinated linkage of mechanical structures. The specific workflow is as follows:

[0049] The operator places the paint can to be filled on the transfer platform 5 and pushes the can along the transfer platform towards the paint discharge pipe 1. During this process, the guide plate 18 at the front end of the positioning insert 10 guides the can through an inclined structure, so that the side of the can gradually fit into the limiting side plate 16, completing the initial positioning. For paint cans of different diameters, the moving adjustment rod 14 on the positioning insert 10 can be adjusted by loosening the bolt at the top of the plate moving groove 13, pushing the moving adjustment rod 14 along the groove to the appropriate position, and then tightening the bolt. The extension distance of the limiting side plate 16 can be adjusted. If it is necessary to replace the limiting side plate 16 of different thickness, the positioning insert 17 can be directly pulled out from the positioning slot 15, replaced, and reinserted, realizing the rapid adaptation of cans of multiple diameters.

[0050] For cans of different heights, the installation position of the electric push rod 23 can be adjusted to adapt: ​​loosen the nut of the front stud 22 of the insert block, move the base insert block 19 longitudinally along the column through groove 9 to the target height, so that the side insert protrusion 21 is inserted into the array slot 20 at the corresponding position, and then tighten the nut to complete the fixation, ensuring that the subsequent closing pressure plate 33 can accurately press the can mouth.

[0051] After the tank is positioned, the control box 6 activates the electric push rod 23, whose output drives the top pressure plate 27 and the bottom support plate 28 to move downwards synchronously. Since the connecting crossbar 31 is positioned in the gap between the top pressure plate 27 and the bottom support plate 28, and the connecting crossbar 31 is fixed to the collar plate 26 via the positioning pin 32, the downward pressure of the top pressure plate 27 drives the collar plate 26 to move downwards along the functional column part 8. The inner protrusion 29 on the inner wall of the collar plate 26 is initially located at the top of the guide groove 25. As the collar plate 26 moves downwards, the inner protrusion 29 slides along the spiral guide groove 25, forcing the collar plate 26 to rotate 90° synchronously, causing the closed pressure plate 33, originally located on the side of the transfer platform 5, to rotate directly above the tank. As the collar plate 26 continues to move downward, the inner protrusion 29 enters the guide longitudinal groove 24 from the end of the guide inclined groove 25. The collar plate 26 stops rotating and descends vertically along the guide longitudinal groove 24, eventually driving the closing pressure plate 33 to press the top opening of the paint tank, forming a sealed tank space, providing a sealed environment for subsequent cleaning operations.

[0052] After the pressure plate 33 is closed and the tank opening is sealed, the control box 6 synchronously starts the high-pressure air source assembly 45 and the negative pressure dust collection assembly 44, and turns on the servo motor 41. The oil-free compressor and drying and filtration system built into the high-pressure air source assembly 45 generate dry and clean high-pressure gas, which is delivered to the connecting sleeve part 39 through the pipeline, and then distributed to the high-pressure air nozzle 37 at the bottom of the closed pressure plate 33. The servo motor 41 drives the drive gear plate part 42 to rotate, which drives the connecting sleeve part 39 to rotate synchronously through the meshing external gear part 40, thereby causing the high-pressure air nozzle 37 to rotate in the negative pressure chamber 35, pushing the gas towards the inner wall and bottom of the tank. The system evenly blows air into the corners and all areas, removing residual dust, metal shavings, and other impurities from the tank walls. The vacuum pump built into the negative pressure suction component 44 generates negative pressure, which is transmitted to the negative pressure chamber 35 through the connecting pipe 43. The annular negative pressure air grooves 36 on the surface of the negative pressure chamber 35 form a uniform negative pressure field, which quickly sucks in the dust and humid air that has been blown up. The air is then transported through the internal channels of the negative pressure chamber 35 and the connecting pipe 43 to the multi-stage filtration system of the negative pressure suction component 44. The dust is trapped and collected, and the clean gas is discharged in compliance with standards. The cleaning process lasts for 3-5 seconds, and the relative humidity drops to below 5%, completing the cleaning and drying process inside the tank.

[0053] Electric push rod 23 drives the top pressure plate 27 and bottom support plate 28 to reset upwards, causing the collar plate 26 to rise along the guide groove 24. The inner protrusion 29 re-enters the guide inclined groove 25 and rotates 90° in the opposite direction, causing the closed pressure plate 33 to return to the side of the transfer platform 5, releasing the limit on the can. Then, the control box 6 starts electric push rod 2, whose output end drives the paint discharge pipe 1 to descend vertically and fill the can. After filling, the operator pushes the paint-filled can on the transfer platform 5 and transports it along the transfer platform to below the capping assembly 7. The operator manually places the can cap on the can opening, and the control box 6 starts the capping assembly 7 to complete the pressing and sealing of the can cap. Then the transfer platform resets, and the next paint can positioning, cleaning, and filling cycle can begin.
