Description

Technical Field

[0001] This utility model relates to the field of acrylic acid technology, and in particular to a coating apparatus for the preparation of acrylic resin. Background Technology

[0002] Acrylic resins are a class of polymer materials produced by polymerization reactions of monomers such as acrylates and methacrylates. They have the characteristics of good weather resistance, high transparency, chemical corrosion resistance, and easy processing, and are widely used in industrial, daily chemical, and medical fields.

[0003] In leather production, applying acrylic resin to leather can give it luster, feel, and water resistance, and repair surface defects. It is commonly used in shoe uppers and bag leather.

[0004] However, most of the coating devices currently used are handheld roller coating devices, which require repeated dipping of acrylic resin for coating. This method is quite cumbersome in actual coating processes. Therefore, we propose a coating device for the preparation of acrylic resin to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing coating devices that use roller brushes, which require dipping acrylic resin in the ink and then brushing it on. This method is cumbersome to operate in actual coating processes. Therefore, this invention proposes a coating device for preparing acrylic resin.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A coating apparatus for preparing acrylic resin, comprising:

[0008] Mounting frame, in which a coating roller is rotatably connected;

[0009] A dispersion mechanism, installed on the top inner wall of the mounting frame, is used to disperse acrylic resin onto the coating roller, and its top extends above the mounting frame.

[0010] A positioning mechanism is installed on the top of the mounting bracket;

[0011] A pushing mechanism, connected to the positioning mechanism, is internally loaded with acrylic resin and docked with the dispersing mechanism, for pushing the acrylic resin to the dispersing mechanism;

[0012] The acrylic resin is fed into the dispersing mechanism and then dispersed and coated onto the coating roller so that the coating roller can apply the acrylic resin to the workpiece.

[0013] In one possible design, the distributed mechanism includes:

[0014] The flow hood is welded to the inner wall of the top of the mounting frame;

[0015] A flow tube is welded through the top inner wall of the flow hood, and its top end extends above the mounting frame and docks with the pushing mechanism;

[0016] V-shaped dispersing mesh plate, welded inside the flow hood;

[0017] A scraper bar is attached to the inner wall of the flow hood, with its bottom in contact with the coating roller;

[0018] The acrylic resin flows into the flow hood and is then dispersed by the V-shaped dispersing mesh and evenly coated onto the coating roller. The scraper is used to help adjust the distribution of the resin on the coating roller.

[0019] In one possible design, baffles are provided on both sides of the flow hood, located on both sides of the coating roller. Arc-shaped slide bars are welded to the side of the two baffles that are close to each other. Annular grooves are provided at both ends of the coating roller. One side of the arc-shaped slide bar extends into the corresponding annular groove and slides tightly against the inner wall of the annular groove to prevent acrylic resin from flowing out from both ends of the coating roller.

[0020] In one possible design, a mounting base is bonded inside the flow tube, and a flow hole is formed on the mounting base. A support plate is integrally formed inside the flow hole, and a movable rod is slidably connected through the support plate. A sealing plate is fixedly installed at the bottom end of the movable rod by a threaded connection. The sealing plate is tightly fitted with the flow hole. A mounting plate is welded to the top end of the movable rod, and a compression spring located on the support plate is sleeved on the movable rod. The compression spring is detachably fixedly connected to the bottom of the mounting plate and the top of the support plate, respectively.

[0021] The upward thrust of the compression spring drives the sealing plate to move upward through the mounting plate and the moving rod, so that the sealing plate fits against the flow hole and prevents acrylic resin from flowing into the flow hood at will. When the pushing mechanism pushes the acrylic resin to the flow tube, the resin pressure pushes the sealing plate downward, so that the flow hole is connected and the acrylic resin flows into the flow hood.

[0022] In one possible design, the positioning mechanism includes a retaining ring welded to the top of the mounting bracket, with positioning screws threaded through the inner side wall of the retaining ring at equal intervals. The bottom of the pushing mechanism extends into the retaining ring, and the plurality of positioning screws are used to brake and limit the pushing mechanism so that the pushing mechanism is stably connected to the flow tube, facilitating the delivery of acrylic resin.

[0023] In one possible design, the push mechanism includes:

[0024] The storage cylinder extends to the retaining ring at the bottom and is braked and positioned by a plurality of the positioning screws;

[0025] The connecting pipe is welded through to the bottom inner wall of the storage cylinder, and the top end of the flow tube extends into the connecting pipe and fits tightly against the inner wall of the connecting pipe.

[0026] A cover plate is tightly threaded to the top opening of the storage cylinder;

[0027] A miniature electric actuator is bolted to the top of the cover plate, and its output shaft extends into the storage cylinder.

[0028] The push plate is fixedly installed on the output shaft of the miniature electric push rod by bolts and slides tightly with the inner wall of the storage cylinder;

[0029] Specifically, activating the micro electric push rod drives the push plate downward, pushing the acrylic resin in the storage cylinder to the connecting pipe, and then conveying it to the flow hood through the flow pipe.

[0030] In one possible design, a fixing frame is welded to the storage cylinder, and handles are welded to both sides of the fixing frame for workers to hold and push the coating roller to move on the workpiece to achieve uniform coating of acrylic resin.

[0031] In one possible design, the flow hood, flow tube, V-shaped dispersing screen, and scraper together constitute the main body of the dispersing mechanism. The flow tube serves as the input channel for acrylic resin, the V-shaped dispersing screen disperses the resin, and the scraper assists the coating roller in uniformly carrying the resin for coating operations.

[0032] In one possible design, the storage cylinder, connecting pipe, cover plate, micro electric push rod, and push plate constitute the pushing mechanism. The storage cylinder stores acrylic resin, and the micro electric push rod drives the push plate to push the resin to the dispersing mechanism, thereby achieving stable resin delivery.

[0033] In this application, during actual use, the storage cylinder is first placed on the retaining ring, and the connecting pipe and the flow pipe are tightly fitted together. Then, by turning multiple positioning screws, the storage cylinder is positioned. Next, acrylic resin is poured into the storage cylinder. Then, the cover plate is tightly threaded onto the storage cylinder. At this point, the operator can hold the handle and place the coating roller on the workpiece to be coated with acrylic resin. The micro electric push rod is activated, causing the push plate to move downwards. This pushes the acrylic resin in the storage cylinder into the connecting pipe. After the acrylic resin flows into the flow pipe, it has downward pressure, thus enabling… The sealing plate moves downwards, keeping the flow hole open. This allows acrylic resin to flow into the flow hood through the flow tube. As the sealing plate moves downwards, the moving rod and mounting plate compress the compression spring, increasing its elastic potential energy. Therefore, when not pushing acrylic resin, the spring force can push the moving rod upwards to reset, sealing the sealing plate and the flow hole and preventing the acrylic resin from moving downwards arbitrarily. The compression spring is detachably connected to the mounting plate and support plate, allowing it to be disassembled, cleaned, or replaced after long-term use, depending on the actual situation.

[0034] After the acrylic resin enters the flow hood, it is dispersed onto the coating roller by the V-shaped dispersing screen. Then, by pulling the handle, the coating roller is driven to roll on the workpiece, so that the acrylic resin can be evenly coated on the workpiece.

[0035] Beneficial effects: In this utility model, the coating device for preparing acrylic resin can, through the dispersion mechanism, allow the acrylic resin to enter the flow hood after flowing into the flow tube, and then disperse and spray the acrylic resin onto the coating roller through the V-shaped dispersion screen so that the acrylic resin can be coated by the coating roller.

[0036] In this utility model, the coating device for preparing acrylic resin can use a positioning mechanism and a retaining ring to position and support the pushing mechanism, so that the pushing mechanism can be stably connected to the flow tube, thereby facilitating the delivery of acrylic resin.

[0037] In this utility model, the coating device for preparing acrylic resin can, through a pushing mechanism, install the storage cylinder on the retaining ring and tightly connect the connecting tube and the flow tube. Then, by activating the micro electric push rod, the push plate is moved downward, which can push the acrylic resin in the storage cylinder into the connecting tube. Then, it can be transported into the flow hood through the flow tube, thereby achieving stable delivery of acrylic resin.

[0038] This invention, after installing the storage cylinder on the retaining ring, uses a miniature electric push rod to pressurize and convey the acrylic resin, which can evenly coat the acrylic resin onto the coating roller. Then, the coating roller rolls on the workpiece, thereby continuously coating the workpiece with acrylic resin, making it easy to use in actual operation. Attached Figure Description

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0046] Example 1: Refer to Figure 1-5A coating apparatus includes a mounting frame 1, within which a coating roller 2 is rotatably connected via bearings. A dispersion mechanism is mounted on the inner top wall of the mounting frame 1, comprising a flow hood 3, a V-shaped dispersion screen 4, a flow tube 5, a mounting base 6, a support plate 7, a moving rod 8, a sealing plate 9, and a compression spring 10. The flow hood 3 is welded to the inner top wall of the mounting frame 1, and the flow tube 5 is welded through the inner top wall of the flow hood 3, with its top end extending above the mounting frame 1. The V-shaped dispersion screen 4 is welded inside the flow hood 3. When acrylic resin flows into the flow hood 3, the V-shaped dispersion screen 4 disperses the acrylic resin, ensuring it is evenly coated onto the coating roller 2. A scraper is adhered to the inner wall of the flow hood 3, with its bottom contacting the coating roller 2. This allows the acrylic resin, after flowing into the flow tube 5, to enter the flow hood 3 and then be dispersed by the V-shaped dispersion screen 4 onto the coating roller 2, whereby the coating roller 2 applies the acrylic resin.

[0047] Both sides of the flow hood 3 are provided with baffles located on both sides of the coating roller 2. Arc-shaped slide bars are welded to the side of the two baffles that are close to each other. Annular grooves 21 are opened at both ends of the coating roller 2. One side of the arc-shaped slide bar extends into the corresponding annular groove 21 and slides tightly with the inner wall of the annular groove 21. The baffles can prevent acrylic resin from flowing out from both ends of the coating roller 2. Furthermore, when the arc-shaped slide bar slides with the corresponding annular groove 21, the sealing effect can be further improved, effectively preventing acrylic resin from flowing out.

[0048] An installation base 6 is bonded inside the flow tube 5. The installation base 6 has a flow hole 61. A support plate 7 is integrally installed inside the flow hole 61. A moving rod 8 is slidably connected through the support plate 7. A sealing plate 9 is fixedly installed at the bottom end of the moving rod 8 via a threaded connection. The sealing plate 9 fits tightly against the flow hole 61. An installation plate is welded to the top end of the moving rod 8. A compression spring 10 is sleeved on the moving rod 8 and located on the support plate 7. The compression spring 10 is detachably fixed to the bottom of the installation plate and the top of the support plate 7. Utilizing the upward thrust of the compression spring 10, the sealing plate 9 can be moved upward via the installation plate and the moving rod 8, ensuring a tight fit between the sealing plate 9 and the flow hole 61, thus preventing acrylic resin from flowing freely into the flow hood 3 through the flow tube 5. After the pushing mechanism pushes the acrylic resin into the flow tube 5, it can push the sealing plate 9 downward, keeping the flow hole 61 open, thus allowing the acrylic resin to flow into the flow hood 3 through the flow tube 5.

[0049] The coating apparatus also includes a positioning mechanism mounted on the top of the mounting frame 1. The positioning mechanism consists of a retaining ring 11 and positioning screws 12. The retaining ring 11 is welded to the top of the mounting frame 1, and the positioning screws 12 are threaded through the inner side wall of the retaining ring 11 at equal intervals. The bottom of the pushing mechanism extends into the retaining ring 11, and the multiple positioning screws 12 are used to brake and limit the pushing mechanism. Using the retaining ring 11 to position and support the pushing mechanism ensures stable docking between the pushing mechanism and the flow tube 5, facilitating the delivery of acrylic resin.

[0050] This application can be used in the field of acrylic acid technology, or in other fields applicable to this application.

[0051] Example 2: Reference Figure 3-5 An improvement upon Example 1: A coating apparatus for preparing acrylic resin, applied in the field of acrylic acid technology, comprising a pushing mechanism connected to a positioning mechanism, consisting of a storage cylinder 13, a cover plate 14, a micro electric push rod 15, a push plate 16, a fixing frame 17, a handle 18, and a connecting pipe 19. The bottom of the storage cylinder 13 extends into the retaining ring 11, and multiple positioning screws 12 are used to brake and position the storage cylinder 13. A connecting pipe 19 is welded through the bottom inner wall of the storage cylinder 13, and the top end of the flow tube 5 extends into the connecting pipe 19 and fits tightly against the inner wall of the connecting pipe 19. The top opening of the storage cylinder 13 is tightly threaded to the cover plate 14, and the top of the cover plate 14 is bolted to the micro electric push rod 15. The output shaft of the micro electric push rod 15 extends into the storage cylinder 13 and is bolted to the push plate 16, which slides tightly against the inner wall of the storage cylinder 13. After the storage cylinder 13 is installed on the retaining ring 11 and the connecting pipe 19 is tightly connected to the flow pipe 5, the push plate 16 is moved downward by starting the micro electric push rod 15, which can push the acrylic resin in the storage cylinder 13 into the connecting pipe 19, and then transport it into the flow hood 3 through the flow pipe 5, so as to achieve stable delivery of acrylic resin.

[0052] A fixing frame 17 is fixedly mounted on the material storage cylinder 13 by welding. Handles 18 are welded on both sides of the fixing frame 17. The two handles 18 make it convenient for the operator to push the coating roller 2 on the workpiece by hand to evenly coat the workpiece with acrylic acid.

[0053] However, as is well known to those skilled in the art, the working principle and wiring method of the miniature electric actuator 15 are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
