Description

Technical Field

[0001] This utility model relates to the field of coating dispersion technology, specifically a UV coating rapid stirring and dispersion device. Background Technology

[0002] UV coatings are coatings that use ultraviolet light as a curing energy source. Under ultraviolet irradiation, the photoinitiator in the coating absorbs energy and initiates the polymerization reaction of the resin and monomers, thereby quickly curing into a film. Before use, UV coatings need to be stirred, mixed and dispersed by a dispersion device to ensure that the coating slurry is evenly distributed.

[0003] For example, Chinese Patent No. CN215654811U discloses a rapid dispersion device for UV coatings, including a base. A telescopic hydraulic cylinder is fixedly connected to the center of one side of the top surface of the base. A transmission box is fixedly connected to the top telescopic end of the telescopic hydraulic cylinder. A bushing is rotatably connected to the center of one side of the bottom surface of the inner wall of the transmission box. Several connecting rods are fixedly connected to the outer wall of the bushing. Several stirring crossbars are fixedly connected to the corresponding sides of the connecting rods. This invention enables the drive gear to drive the second bevel gear and the first bevel gear to rotate in opposite directions under the drive of the speed-regulating motor, thereby causing the rotating shaft and the bushing to rotate in opposite directions. This causes the several dispersing stirring blades and the several connecting rods to rotate in opposite directions, thereby breaking the vortex balance and making the vortex direction of each layer opposite. The impact of the vortices can quickly disperse the particles, improve the dispersion speed, and improve practicality.

[0004] In the technical solution described in this plan, the dispersing and stirring blades are fixedly installed on the outer wall of the rotating shaft. When the stirring blades are worn, deformed, or damaged, due to their fixed installation, they are not easy to disassemble, which requires the replacement of the entire stirring shaft and stirring blade assembly, increasing costs and making maintenance difficult. Utility Model Content

[0005] The purpose of this invention is to provide a rapid stirring and dispersing device for UV coatings to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A rapid stirring and dispersing device for UV coatings includes a cylindrical assembly, a lifting assembly, a driving assembly, and a stirring assembly. The lifting assembly is located outside the cylindrical assembly, the driving assembly is located above the lifting assembly, and the stirring assembly is located inside the cylindrical assembly. The lifting assembly is used to adjust the height of the driving assembly, the driving assembly is used to drive the stirring assembly, and the stirring assembly is used for stirring. The stirring assembly includes two stirring shafts. A pair of collars are fitted on the outer wall of each stirring shaft. Vertical grooves are formed on both the front and back of the outer side of each stirring shaft, and a pair of horizontal grooves are formed on one side of the outer wall of each stirring shaft located at the same level. Movable blocks are provided inside each pair of horizontal grooves at the same level. The outer walls of the pair of movable blocks are connected to the inner walls of the collars. Stirring blades are connected to both the front and back of each collar.

[0008] Furthermore, the outer wall of the moving block slides in conjunction with the inner wall of the horizontal groove and the vertical groove. The stirring shaft has a first threaded hole in the horizontal groove. The pair of moving blocks and the collar have second threaded holes on both sides of the moving block. The second threaded hole and the first threaded hole are threaded together at the same level. One end of the bolt has an internal hexagonal groove.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the second threaded hole, the first threaded hole, and the bolt, the collar on the stirring shaft is first disassembled from bottom to top. Through the internal hexagonal groove at one end of the bolt, one end of the internal hexagonal wrench is inserted into the internal hexagonal groove, and then the internal hexagonal wrench is rotated to loosen the bolt and remove it. At this time, the collar and the stirring shaft will no longer be in a fixed state. Then, the collar is rotated to move the moving block on the inner wall of the collar from the horizontal groove to the vertical groove. When the moving block is completely located in the vertical groove, the collar is moved downward to move the moving block down in the vertical groove, thereby completing the disassembly of the collar. The operator checks the wear of the stirring blade and replaces the collar and the stirring blade as a whole.

[0010] Furthermore, the cylindrical assembly includes a stirring drum, a feed pipe is connected to one side of the outer wall of the stirring drum near the upper end, a flow meter is installed at the end of the feed pipe away from the stirring drum, four support legs are installed at equal intervals on the outer wall of the stirring drum near the bottom end, a discharge pipe is connected to the bottom end of the stirring drum, and a solenoid valve is installed at the end of the discharge pipe away from the stirring drum.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the feed pipe and the flow meter, the feed pipe can be connected to the discharge end of the pump through an external pipe, and then the feed end of the pump can be connected to the material cylinder for storing paint through an external pipe. When the pump is started to send the paint into the mixing drum, the flow rate of the paint flowing through the feed pipe is monitored by the flow sensor. Through the combined use of the discharge pipe and the solenoid valve, when the mixing and dispersion are completed, the solenoid valve is opened to allow the mixed and dispersed paint to be discharged through the discharge pipe.

[0012] Furthermore, the lifting assembly includes a support, which is installed on the outer wall of the mixing drum, and the support has a pair of mounting slots inside, each of which is equipped with a hydraulic rod. The drive assembly includes a connecting plate, and the movable ends of the pair of hydraulic rods are connected to the bottom end of the connecting plate. A drum cover is installed at the bottom end of the connecting plate. The upper ends of the two mixing shafts extend through the drum cover into the interior, and the upper ends of the two mixing shafts are respectively connected to the top end of the interior of the drum cover via bearings.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting a hydraulic rod, the height of the drive component can be easily controlled when the hydraulic rod is working, so that the cover and the mixing drum are in an open or closed state.

[0014] Furthermore, the bottom end of the cylinder cover fits into the top end of the mixing cylinder.

[0015] Furthermore, a rotating shaft is rotatably connected to the inner center of the cylinder cover, and a first gear is sleeved on the outside of the rotating shaft. A second gear is sleeved on the outside of one of the stirring shafts near the upper end. The first gear and the second gear mesh with each other. A synchronous pulley is sleeved on the outside of the rotating shaft and another stirring shaft. A synchronous belt is wound between the pair of synchronous pulleys.

[0016] The beneficial effect of adopting the above-mentioned further scheme is that one of the stirring shafts is the stirring shaft on the left side of the rotating shaft, and the other stirring shaft is the stirring shaft on the right side of the rotating shaft. Since the first gear and the second gear mesh, by setting the rotating shaft, when the rotating shaft rotates, the first gear rotates and drives the second gear to rotate, thereby realizing the rotation of the stirring shaft on the left side of the rotating shaft. When the rotating shaft rotates, the stirring shaft on the right side of the rotating shaft is realized to rotate under the transmission action of the synchronous pulley and the synchronous belt. At this time, the stirring shafts on the left and right sides of the rotating shaft rotate in opposite directions.

[0017] Furthermore, a servo motor is mounted on the top of the connecting plate, and the output end of the servo motor is connected to the rotating shaft via a transmission connection.

[0018] The advantage of adopting the above-mentioned further solution is that by installing a servo motor, it is easier to drive the shaft to rotate when the servo motor is working.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This UV coating rapid stirring and dispersing device connects the vertical and horizontal grooves. Through the cooperation of the second threaded hole, the first threaded hole, and the bolt, the collar on the stirring shaft is first disassembled from bottom to top. Using the internal hexagonal groove at one end of the bolt, one end of an internal hexagonal wrench is inserted into the groove, and then the wrench is rotated to loosen and remove the bolt. At this point, the collar and the stirring shaft are no longer fixed. Then, the collar is rotated, causing the moving block on the inner wall of the collar to move from the horizontal groove to the vertical groove. When the moving block is completely within the vertical groove, the collar is moved downwards so that the moving block... The vertical groove moves downward, thus completing the disassembly of the ring. The operator checks the wear of the stirring blades and replaces the ring and stirring blades as a whole. When the servo motor is working, it facilitates the rotation of the rotating shaft. Due to the meshing of the first gear and the second gear, the rotating shaft is set up so that when the rotating shaft rotates, the first gear rotates and drives the second gear to rotate, realizing the rotation of the stirring shaft on the left side of the rotating shaft. When the rotating shaft rotates, the stirring shaft on the right side of the rotating shaft is realized to rotate under the transmission action of the synchronous pulley and the synchronous belt. At this time, the stirring shafts on the left and right sides of the rotating shaft rotate in opposite directions, and the coating in the mixing drum is mixed and dispersed under the action of the ring and the external stirring blades.

[0029] Please see Figures 1-5This utility model provides a technical solution: the cylinder assembly 1 includes a stirring cylinder 11, with a feed pipe connected to one side of the outer wall of the stirring cylinder 11 near the upper end. A flow meter 12 is installed at the end of the feed pipe away from the stirring cylinder 11. Four support legs 13 are evenly installed on the outer wall of the stirring cylinder 11 near the bottom end. A discharge pipe is connected to the bottom end of the stirring cylinder 11, with a solenoid valve installed at the end of the discharge pipe away from the stirring cylinder 11.

Through the cooperation of the feed pipe and the flow meter 12, the feed pipe can be connected to the discharge end of the pump through an external pipe, and then the feed end of the pump can be connected to the material cylinder for storing paint through an external pipe. When the pump is started, the paint is sent into the mixing cylinder 11. The flow rate of the paint flowing through the feed pipe is monitored by the flow sensor. Through the cooperation of the discharge pipe and the solenoid valve, after the mixing and dispersion are completed, the solenoid valve is opened to allow the mixed and dispersed paint to be discharged through the discharge pipe. By setting the hydraulic rod 22, when the hydraulic rod 22 is working, it is easy to control the height of the drive component 3, so that the cylinder cover 33 and the mixing cylinder 11 are in an open or closed state.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5This utility model provides a technical solution: the bottom end of the cylinder cover 33 is fitted to the top end of the stirring cylinder 11. A rotating shaft 34 is rotatably connected to the center of the cylinder cover 33. A first gear 35 is sleeved on the outside of the rotating shaft 34. A second gear 36 is sleeved on the outside of one of the stirring shafts 41 near its upper end. The first gear 35 and the second gear 36 mesh with each other. A synchronous pulley 37 is sleeved on the outside of the rotating shaft 34 and the other stirring shaft 41. A synchronous belt 38 is wound between the pair of synchronous pulleys 37. A servo motor 32 is installed on the top end of the connecting plate 31. The output end of the servo motor 32 is connected to the rotating shaft 34 for transmission. 32. When the servo motor 32 is working, it facilitates the rotation of the rotating shaft 34. One of the stirring shafts 41 is the stirring shaft 41 on the left side of the rotating shaft 34, and the other stirring shaft 41 is the stirring shaft 41 on the right side of the rotating shaft 34. Since the first gear 35 and the second gear 36 are meshed, by setting the rotating shaft 34, when the rotating shaft 34 rotates, the first gear 35 rotates and drives the second gear 36 to rotate, so that the stirring shaft 41 on the left side of the rotating shaft 34 rotates. When the rotating shaft 34 rotates, the stirring shaft 41 on the right side of the rotating shaft 34 rotates under the transmission action of the synchronous pulley 37 and the synchronous belt 38. At this time, the stirring shafts 41 on the left and right sides of the rotating shaft 34 rotate in opposite directions.

[0032] Specifically, the working principle of this UV coating rapid mixing and dispersing device is as follows: During use, the feed pipe is connected to the pump's discharge end via an external pipe, and then the pump's feed end is connected to the coating storage cylinder via an external pipe. When the pump is started, the coating is fed into the mixing drum 11. The flow rate of the coating flowing through the feed pipe is monitored by a flow sensor. When the servo motor 32 is working, it drives the rotating shaft 34 to rotate, causing the first gear 35 to rotate and drive the second gear 36 to rotate, thus rotating the mixing shaft 41 on the left side of the rotating shaft 34. When the rotating shaft 34 rotates, the mixing shaft 41 on the right side of the rotating shaft 34 rotates under the transmission action of the synchronous pulley 37 and the synchronous belt 38. At this time, the left and right sides of the rotating shaft 34's mixing shafts 41 rotate in opposite directions, and under the action of the collar 45 and the external mixing blades 46, the coating in the mixing drum 11 is mixed and dispersed. After the mixing and dispersion are completed, the solenoid valve is opened to... After the coating is stirred and dispersed, it is discharged through the discharge pipe. Then, the hydraulic rod 22 is activated so that its movable end pushes the drive assembly 3 upward to separate the cylinder cover 33 from the mixing cylinder 11. When the mixing assembly 4 needs maintenance after long-term use, the operator first removes the collar 45 on the mixing shaft 41 from bottom to top. Through the internal hexagonal groove at one end of the bolt 49, one end of the internal hexagonal wrench is inserted into the internal hexagonal groove, and then the internal hexagonal wrench is rotated to loosen the bolt 49 and remove it. At this time, the collar 45 and the mixing shaft 41 will no longer be in a fixed state. Then, the collar 45 is rotated so that the moving block 44 on the inner wall of the collar 45 moves from the horizontal groove 43 to the vertical groove 42. When the moving block 44 is completely in the vertical groove 42, the collar 45 is moved downward so that the moving block 44 moves down in the vertical groove 42, thereby completing the removal of the collar 45. The operator checks the wear of the mixing blade 46 and replaces the collar 45 and the mixing blade 46 as a whole.
