Description

Technical Field

[0001] This invention relates to the field of plaster liquid coating technology, specifically a plaster liquid quantitative coating machine. Background Technology

[0002] The plaster coating machine is a core automated piece of equipment in the large-scale production of plasters. Its main function is to automatically coat viscous medicinal liquids or functional materials, such as plasters, cold compress gels, and traditional Chinese medicine extracts, onto the surface of substrates such as non-woven fabrics and films according to a preset precise dosage and uniform thickness. In the plaster production process, the quantitative coating of the medicinal liquid is a key step that determines the uniformity and effectiveness of product quality, and the cleanliness of the coating equipment directly affects the coating accuracy, product qualification rate, and equipment lifespan.

[0003] After traditional coating machines complete the application of medicated plaster solution, a large amount of residual solution remains on the surfaces of the metering roller and coating roller. This residual solution has a complex composition, containing various traditional Chinese medicine extracts and adhesive substances, and is extremely prone to drying and hardening. Once hardened, it forms stubborn stains that are difficult to remove completely with simple wiping. Over time, this not only affects the precision of the metering and coating rollers, leading to uneven application of the medicated solution, but also causes deviations in the thickness and weight of the plaster, reducing the stability of the plaster's quality and impacting its efficacy and market competitiveness. Traditional cleaning methods are mostly manual, requiring workers to repeatedly wipe the metering and coating rollers with brushes and cloths. This method is not only labor-intensive but also slow, severely impacting production efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a quantitative coating machine for plasters and medicines, which solves the problems of high labor intensity and slow cleaning speed caused by manual operation, which seriously affects production efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plaster liquid quantitative coating machine, comprising a base plate, an adjustment mechanism and a conveyor belt on the upper surface of the base plate, a metering roller and a coating roller connected to the adjustment mechanism, a gantry frame fixedly connected to the upper surface of the base plate, a liquid tank fixedly connected to the outer wall of the gantry frame, an extrusion head fixedly installed on the outer wall of the liquid tank, a drive mechanism on the outer wall of the gantry frame, a sliding frame II connected to the drive mechanism, a fixed rod slidably connected inside the sliding frame II, both ends of the fixed rod being fixedly connected to the outer wall of the gantry frame, and a sponge brush fixedly installed on the outer wall of the sliding frame II.

[0006] Through the above solution: After the coating machine completes the plaster coating operation, cleaning solution is added to the medicine tank and sprayed onto the surface of the metering roller and coating roller through the extrusion head. Then, the drive mechanism drives the sliding frame two to slide along the fixed rod, thereby causing the sponge brush fixed on the sliding frame two to slide against the metering roller and coating roller. The metering roller and coating roller rotate and cooperate, effectively avoiding the impact of medicine residue on subsequent coating operations, while also extending the service life of the metering roller and coating roller and improving cleaning efficiency.

[0007] Preferably, the adjustment mechanism includes a slide table, the lower surface of which is fixedly connected to the upper surface of the base plate, a sliding frame slidably connected to the upper surface of the slide table, a metering roller and a coating roller rotatably connected to both sides of the sliding frame slid, and an electric push rod slidably connected to the outer wall of both sides of the sliding frame slid, the electric push rod slidably installed on the upper surface of the slide table.

[0008] Preferably, the driving mechanism includes a motor, the outer wall of which is fixedly installed on the outer wall of the gantry frame, the output end of which is fixedly connected to one end of a lead screw, the other end of which is rotatably connected to the outer wall of the gantry frame, and the outer wall of the lead screw is threadedly connected to a sliding frame.

[0009] Preferably, a cleaning box is fixedly connected to the outer wall of the medicine tank, the cleaning box is connected to the medicine tank, one end of a connecting pipe is fixedly connected to the lower surface of the cleaning box, the other end of the connecting pipe is fixedly connected to a valve body, a nozzle is fixedly connected to the lower surface of the valve body, valve pipes are fixedly connected to both the upper and lower interiors of the valve body, the upper and lower valve pipes are respectively connected to the connecting pipe and the nozzle, a valve plate is slidably connected between the upper and lower valve pipes, and the valve plate has a valve hole.

[0010] Preferably, a bracket is fixedly connected to the lower surface of the cleaning box, the outer wall of the bracket is slidably connected to the valve body, one end of a slide rod is fixedly connected to the outer wall of the valve plate, a magnetic block one is fixedly connected to the other end of the slide rod, a magnetic block two is attached to the outer wall of the magnetic block one, one end of a connecting rod is fixedly connected to the lower surface of the magnetic block two, and the other end of the connecting rod is fixedly connected to the upper surface of the sliding frame two.

[0011] Preferably, one end of a tension spring is fixedly connected to the outer wall of the magnetic block, and the other end of the tension spring is fixedly connected to the outer wall of the valve body.

[0012] Preferably, the outer wall of the gantry frame is fixedly connected to an extrusion plate and a collection box one, the collection box one being located below the extrusion plate, and the outer wall of the sliding frame two is fixedly connected to a side plate, the extrusion plate being L-shaped.

[0013] Preferably, an electric push rod two is fixedly connected to the upper surface of the base plate, and a baffle is fixedly connected to the output end of the electric push rod two. The baffle is U-shaped.

[0014] Preferably, a rotating shaft is rotatably connected to the outer wall of the baffle, a second motor is fixedly connected to the outer wall of the baffle, the output end of the second motor is fixedly connected to the rotating shaft, and a cleaning brush is fixedly connected to the outer wall of the rotating shaft.

[0015] Preferably, collection boxes are provided on both sides of the conveyor belt, and the collection boxes are located inside the wing plates on both sides of the baffle.

[0016] Working principle: The film is placed on the conveyor belt, and the motor is started to drive the conveyor belt to move smoothly. At the same time, the plaster in the medicine tank is squeezed or pumped out from the extrusion head and falls on the upper side of the metering roller and coating roller. The plaster passes through the gap between the metering roller and the coating roller, and is then transferred to the film by the rotating coating roller, completing the plaster coating process.

[0017] During the coating process, to achieve precise quantitative coating, an electric push rod drives a sliding frame to slide, thereby adjusting the gap between the metering roller and the coating roller. By changing this gap, the feeding speed of the plaster can be adjusted. At the same time, the rotation speed of the coating roller is precisely controlled. The two work together to ultimately achieve quantitative coating of the plaster, ensuring that the amount of plaster on each substrate meets the requirements.

[0018] After coating is completed, cleaning fluid is sprayed first. This can be done by adding cleaning fluid to the chemical tank, allowing it to be sprayed from the extruder onto the metering and coating rollers; secondly, by transferring the cleaning fluid to the chemical tank via a solenoid valve between the cleaning and chemical tanks before it is sprayed out through the extruder; thirdly, by using the valve body and nozzle to directly spray the cleaning fluid onto the metering and coating rollers. Next, sponge brush cleaning is performed. Motor 1 of the drive mechanism drives the lead screw to rotate, pushing sliding frame 2 along the fixed rod, causing the sponge brush to slide against the metering and coating rollers, completing the cleaning process in conjunction with the roller rotation. When sliding frame 2 brings the sponge brush close to the valve body, magnetic block 2 attracts magnetic block 1, which opens the valve plate via the slide rod, allowing the cleaning fluid to fall onto the sponge brush. Sliding frame 2 continues to slide, keeping the nozzle always aligned with the sponge brush. After the valve body slides to the end of the support, magnetic block 2 disengages from magnetic block 1, the tension spring resets, and the valve plate closes the valve body. Finally, clean the sponge brush. The sliding frame continues to slide, bringing the sponge brush closer to the squeezing plate. The squeezing plate and the side plate work together to squeeze the sponge brush, draining the water and reducing corrosion and dripping. The cleaning solution can be sprayed and squeezed repeatedly to thoroughly clean the sponge brush.

[0019] The conveyor belt is cleaned simultaneously with the metering and coating rollers. Electric push rod two lowers a baffle, bringing it into contact with the upper surface of the conveyor belt. Motor two then rotates the shaft and cleaning brush, causing the conveyor belt and cleaning brush to reverse direction, thus cleaning the conveyor belt. To collect the cleaning fluid generated during the cleaning process, collection boxes two are installed on both sides of the conveyor belt. The baffles are U-shaped and their length covers both collection boxes two, effectively blocking the cleaning fluid on the conveyor belt and causing it to fall into the collection boxes two, preventing the cleaning fluid from flowing everywhere.

[0020] This invention provides a quantitative coating machine for plaster medications. It has the following beneficial effects: 1. This invention allows for the addition of cleaning solution to the chemical tank after coating, which is then sprayed onto the metering roller and coating roller through the extrusion head. The driving mechanism drives the sliding frame and sponge brush to slide, cooperating with the rotation of the metering roller and coating roller. The sponge brushes on both sides can clean both rollers separately, ensuring the cleanliness of the equipment, extending the service life of the equipment, and improving cleaning efficiency.

[0021] 2. This invention utilizes the cooperation of magnetic block one, magnetic block two, connecting rod, sliding rod, and tension spring. When the sliding frame two moves the sponge brush close to the valve body, the magnetic attraction causes the valve plate to open, and the cleaning liquid falls onto the sponge brush. As the sliding frame two continues to slide, the nozzle can always be aligned with the sponge brush. After the sliding frame two continues to slide and the magnetic block disengages, the tension spring resets and causes the valve plate to close the valve body, thus achieving automatic control. This is convenient to operate and saves resources.

[0022] 3. The extrusion plate on the outer wall of the gantry frame of the present invention cooperates with the side plate on the sliding frame 2. When the sliding frame 2 drives the sponge brush to slide to the extrusion plate, it can squeeze the sponge brush to drain the water, reduce the corrosion of the cleaning liquid, and prevent the sponge brush from continuously dripping water. It can also clean the sponge brush by repeatedly spraying cleaning liquid and squeezing, thus ensuring the cleanliness and performance of the sponge brush.

[0023] 4. The electric push rod of the present invention drives the baffle to rise and fall. When cleaning, it can lower to block water. The rotating shaft on the baffle, the motor and the cleaning brush work together. When cleaning the metering roller and the coating roller, the cleaning brush can rotate to clean the conveyor belt. The collection boxes on both sides of the conveyor belt can collect the cleaning liquid to prevent the cleaning liquid from overflowing, ensuring the cleanliness of the equipment and the surrounding environment, and improving the overall cleaning effect of the equipment.

Detailed Implementation

[0026] The technical solution of the present invention will now be clearly and completely described 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.

[0027] Please see the appendix Figure 1 -Appendix Figure 4 This invention provides a plaster liquid quantitative coating machine, including a base plate 1. An adjustment mechanism 2 and a conveyor belt 5 are provided on the upper surface of the base plate 1. The adjustment mechanism 2 is connected to a metering roller 3 and a coating roller 4. A gantry frame 11 is fixedly connected to the upper surface of the base plate 1. A liquid tank 6 is fixedly connected to the outer wall of the gantry frame 11. An extrusion head 8 is fixedly installed on the outer wall of the liquid tank 6. A drive mechanism 7 is provided on the outer wall of the gantry frame 11. A sliding frame 9 is connected to the drive mechanism 7. A fixed rod 10 is slidably connected inside the sliding frame 9. Both ends of the fixed rod 10 are fixedly connected to the outer wall of the gantry frame 11. A sponge brush 12 is fixedly installed on the outer wall of the sliding frame 9.

[0028] Specifically, this application is used for coating plasters. During coating, the substrate is placed on a conveyor belt 5, which is driven by a motor or other means to move the substrate on the conveyor belt 5. At the same time, the plaster to be coated is placed inside the medicine tank 6. The plaster is extruded from the extruder 8 by squeezing or pumping. The plaster falls on the upper side of the metering roller 3 and the coating roller 4. The plaster first passes through the gap between the metering roller 3 and the coating roller 4. Both the metering roller 3 and the coating roller 4 are driven to rotate by a motor. Then, the plaster is transferred to the substrate by the coating roller 4 to complete the coating. After the coating is completed, the medicine tank 6 is filled with... Cleaning fluid is added and then sprayed onto the upper surfaces of metering roller 3 and coating roller 4 through extrusion head 8. When metering roller 3 and coating roller 4 approach sponge brush 12, the sliding frame 9 is driven to slide by drive mechanism 7, thereby causing sponge brush 12 to slide against metering roller 3 and coating roller 4. Fixed rod 10 supports sliding frame 9. Sponge brush 12 cleans metering roller 3 and coating roller 4. In this application, sponge brush 12 is provided on both sides of metering roller 3 and coating roller 4, respectively for cleaning metering roller 3 and coating roller 4. When sponge brush 12 slides, metering roller 3 and coating roller 4 rotate to cooperate in cleaning.

[0029] Please see the appendix Figure 2 -Appendix Figure 3 The adjustment mechanism 2 includes a slide table 201. The lower surface of the slide table 201 is fixedly connected to the upper surface of the base plate 1. A sliding frame 202 is slidably connected to the upper surface of the slide table 201. A metering roller 3 and a coating roller 4 are rotatably connected to the two sliding frames 202. An electric push rod 203 is fixedly connected to the outer wall of the two sliding frames 202. The electric push rod 203 is fixedly installed on the upper surface of the slide table 201.

[0030] Specifically, the distance between the metering roller 3 and the coating roller 4 in this application is adjustable. That is, two electric push rods 203 are respectively provided on the upper side of the slide table 201. The electric push rods 203 drive the sliding frame 202 at the output end to slide, thereby realizing the sliding of the metering roller 3 and the coating roller 4. By adjusting the gap between the metering roller 3 and the coating roller 4, the feeding speed of the plaster can be changed. By controlling the rotation speed of the coating roller 4, the effect of quantitative coating can be achieved. During cleaning, the sponge brush 12 can be brought close to the metering roller 3 and the coating roller 4 by sliding the metering roller 3 and the coating roller 4.

[0031] Please see the appendix Figure 3 The drive mechanism 7 includes a motor 701. The outer wall of the motor 701 is fixedly installed on the outer wall of the gantry frame 11. One end of the lead screw 702 is fixedly connected to the output end of the motor 701. The other end of the lead screw 702 is rotatably connected to the outer wall of the gantry frame 11. The outer wall of the lead screw 702 is threadedly connected to the sliding frame 9.

[0032] Specifically, this application drives the sliding frame 9 to slide via the lead screw 702. When the start motor 701 drives the lead screw 702 at the output end to rotate, the lead screw 702 is threadedly connected to the sliding frame 9, thereby pushing the sliding frame 9 to slide.

[0033] Please see the appendix Figure 4 -Appendix Figure 6 A cleaning box 13 is fixedly connected to the outer wall of the medicine tank 6. The cleaning box 13 is connected to the medicine tank 6. One end of the connecting pipe 14 is fixedly connected to the lower surface of the cleaning box 13. The other end of the connecting pipe 14 is fixedly connected to the valve body 15. The nozzle 16 is fixedly connected to the lower surface of the valve body 15. Valve pipes 18 are fixedly connected to both the upper and lower interiors of the valve body 15. The upper and lower valve pipes 18 are respectively connected to the connecting pipe 14 and the nozzle 16. A valve plate 19 is slidably connected between the upper and lower valve pipes 18. The valve plate 19 has a valve hole.

[0034] Specifically, the cleaning tank 13 is used to store cleaning fluid. A solenoid valve is installed between the cleaning tank 13 and the medicine tank 6, allowing the cleaning fluid to be directly transferred into the medicine tank 6 during cleaning. Two sets of connecting pipes 14 are installed on the lower surface of the cleaning tank 13, corresponding to the sponge brushes 12 on both sides. The cleaning tank 13 is connected to the connecting pipes 14, which are also connected to the valve body 15. The valve body 15 is located on one side of the metering roller 3 and is connected to the nozzle 16. After cleaning with the sponge brushes 12, the cleaning fluid can be removed by... 12 slides to the underside of the nozzle 16, and the nozzle 16 sprays cleaning fluid onto the sponge brush 12, thereby cleaning the sponge brush 12 in a targeted manner and improving the service life of the sponge brush 12. In this application, a valve tube 18 and a valve plate 19 are provided inside the valve body 15 to control the opening and closing of the valve body 15. When the valve hole of the valve plate 19 is aligned with the upper and lower valve tubes 18, the cleaning fluid flows normally. When the valve plate 19 is misaligned with the valve tube 18, the valve plate 19 blocks the valve tube 18, and the cleaning fluid cannot flow out from the nozzle 16.

[0035] Please see the appendix Figure 5 -Appendix Figure 7 A bracket 17 is fixedly connected to the lower surface of the cleaning box 13. The outer wall of the bracket 17 is slidably connected to the valve body 15. One end of the slide rod 20 is fixedly connected to the outer wall of the valve plate 19. The other end of the slide rod 20 is fixedly connected to a magnetic block 21. A magnetic block 22 is attached to the outer wall of the magnetic block 21. One end of the connecting rod 23 is fixedly connected to the lower surface of the magnetic block 22. The other end of the connecting rod 23 is fixedly connected to the upper surface of the sliding frame 9.

[0036] Specifically, to avoid wasting cleaning fluid, this application has a connecting rod 23 connected to the upper surface of the sliding frame 2 9. A magnetic block 22 is fixedly connected to the connecting rod 23. That is, when the sliding frame 2 9 moves the sponge brush 12 close to the valve body 15, the magnetic block 22 attracts the magnetic block 1 21. The magnetic block 1 21 drives the slide rod 20 to slide, thereby driving the valve plate 19 to open through the slide rod 20. At this time, the cleaning fluid falls on the sponge brush 12. At the same time, the sliding frame 2 9 continues to slide, which can drive the magnetic block 22 and the magnetic block 1 21 to slide. The magnetic block 1 21 drives the valve body 15 to slide through the slide rod 20. The bracket 17 supports the sliding of the valve body 15, so that the nozzle 16 is always aligned with the sponge brush 12.

[0037] Please see the appendix Figure 5 - Appendix Figure 6 One end of a tension spring 24 is fixedly connected to the outer wall of the magnetic block 21, and the other end of the tension spring 24 is fixedly connected to the outer wall of the valve body 15.

[0038] Specifically, when magnetic block 22 and magnetic block 21 are attracted together, the tension spring 24 is stretched. When the valve body 15 slides to the end of the bracket 17, the sliding frame 29 drives the sponge brush 12 to slide continuously, causing magnetic block 22 to disengage from magnetic block 21. The tension spring 24 returns to its original position, and under the tension of the tension spring 24, magnetic block 21 slides, thereby resetting the valve plate 19 and closing the valve body 15, thus completing the reset.

[0039] Please see the appendix Figure 7 The outer wall of the gantry frame 11 is fixedly connected to an extrusion plate 25 and a collection box 26. The collection box 26 is located on the lower side of the extrusion plate 25. The outer wall of the sliding frame 9 is fixedly connected to a side plate 33. The extrusion plate 25 is L-shaped.

[0040] Specifically, after the sliding frame 29 causes the magnetic block 22 to detach from the magnetic block 1 21, it continues to slide, which can bring the sponge brush 12 closer to the squeezing plate 25. The cooperation between the squeezing plate 25 and the side plate 33 can squeeze the sponge brush 12 to drain the water from the sponge brush 12, reduce the corrosion of the cleaning liquid, and prevent the sponge brush 12 from continuously dripping water. This application can clean the sponge brush 12 by repeatedly spraying cleaning liquid and squeezing it.

[0041] Please see the appendix Figure 8 An electric push rod 27 is fixedly connected to the upper surface of the base plate 1. A baffle 28 is fixedly connected to the output end of the electric push rod 27. The baffle 28 is U-shaped.

[0042] Specifically, the electric push rod 27 can drive the baffle 28 to rise and fall. When cleaning the metering roller 3 and coating roller 4, the conveyor belt 5 is started, and the baffle 28 is lowered at the same time, so that the lower surface of the baffle 28 is in contact with the upper surface of the conveyor belt 5, and the water is blocked on one side of the baffle 28.

[0043] Please see the appendix Figure 8 A rotating shaft 29 is rotatably connected to the outer wall of the baffle 28, and a motor 31 is fixedly connected to the outer wall of the baffle 28. The output end of the motor 31 is fixedly connected to the rotating shaft 29, and a cleaning brush 30 is fixedly connected to the outer wall of the rotating shaft 29.

[0044] Specifically, a rotating shaft 29 is set on the side near the metering roller 3 and the coating roller 4. The baffle 28 supports the rotation of the rotating shaft 29. When cleaning the metering roller 3 and the coating roller 4, the cleaning liquid of the metering roller 3 and the coating roller 4 falls directly onto the upper surface of the conveyor belt 5. The rotating shaft 29 at the output end is driven to rotate by starting the motor 31. The rotating shaft 29 drives the cleaning brush 30 to rotate. At this time, the cleaning brush 30 has descended synchronously with the baffle 28 to fit against the conveyor belt 5. The conveyor belt 5 and the cleaning brush 30 reverse their directions, which can clean the conveyor belt 5.

[0045] Please see the appendix Figure 8 Collection boxes 32 are provided on both sides of the conveyor belt 5. The collection boxes 32 are located on the inner side of the wing plates on both sides of the baffle 28.

[0046] Specifically, collection boxes 32 are installed on both sides of the conveyor belt 5. The collection boxes 32 are fixed to the outer wall of the side frame of the conveyor belt 5. The collection boxes 32 are used to collect cleaning fluid. Since the baffle 28 is U-shaped and the collection boxes 32 are located inside the wing plates on both sides of the baffle 28, that is, the length of the baffle 28 covers the collection boxes 32 on both sides, the cleaning fluid on the conveyor belt 5 can be blocked. Under the continuous movement of the conveyor belt 5, the cleaning fluid falls into the interior of the collection boxes 32.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
