Description

Technical Field

[0001] This utility model relates to the field of scraper coating machine technology, and in particular to a precision coating thickness adjustment device for scraper coating machines. Background Technology

[0002] In fields such as coating, printing, and electronic material preparation, blade coating technology is widely used to uniformly coat liquids or slurries (such as lithium battery electrode slurries, optical thin film coatings, PCB inks, etc.).

[0003] Existing coating equipment typically requires workers to attach a wire rod to a moving frame during coating, making it impossible to adjust the coating thickness. This necessitates multiple coating operations to achieve the desired coating thickness. Furthermore, manually dripping the slurry onto the material plate during coating can result in insufficient slurry, requiring workers to add more slurry and continue the coating process, which is extremely inconvenient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot adjust coating thickness, and to provide a precision coating thickness adjustment device for a scraper coating machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a coating machine body, a placement platform fixedly connected to the outer surface of the coating machine body, a movable frame sleeved on the outer surface of the placement platform, a support rod fixedly connected to the outer surface of the movable frame, a holding box sleeved on the outer surface of the support rod, a second knob on one side of the movable frame, a lead screw fixedly connected to one side of the second knob, a bearing fixedly connected to one end of the lead screw, the bearing being placed inside the movable frame, a movable plate sleeved on the outer surface of the lead screw, a fixing rod fixedly connected to the outer surface of the movable plate, and a wire rod sleeved on the outer surface of the fixing rod.

[0006] In a preferred embodiment, the inner wall of the container is provided with a blocking block, the outer surface of the container is fixedly connected with a locking block, one side of the support rod is provided with a slider, one end of the slider is fixedly connected with a blocking block, one side of the blocking block is fixedly connected with a spring, and one side of the blocking block is fixedly connected with a limit rod.

[0007] In a preferred embodiment, the outer surface of the support rod is provided with a slot, the outer surface of the locking block is engaged with the inner wall of the slot, the inner wall of the support rod is provided with a through hole, the outer surface of the limiting rod is slidably connected with the inner wall of the through hole, and one end of the spring is slidably connected with the inner wall of the through hole.

[0008] In a preferred embodiment, the outer surface of the fixing rod is rotatably connected to the inner wall of the wire rod.

[0009] In a preferred embodiment, the outer surface of the lead screw is threaded to one end of the movable plate, and a sliding groove is provided on one side of the movable frame, with one end of the movable plate slidably connected to the sliding groove.

[0010] In a preferred embodiment, a rotating rod is sleeved on the inner wall of the blocking block, and a first knob is fixedly connected to one end of the rotating rod, which is threadedly connected to the inner wall of the container.

[0011] In a preferred embodiment, one side of the blocking block is abutted against one side of the card block, and the outer surface of the blocking block is slidably connected to the inner wall of the through hole.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, when adjusting the coating thickness during the coating process, the second knob is turned to rotate the lead screw inside the bearing. Since the lead screw is threadedly connected to the moving plate, the moving plate moves inside the slide groove while the lead screw rotates. The movement of the moving plate moves the fixed rod, thereby adjusting the distance between the wire rod and the coating material, thus achieving the purpose of coating thickness adjustment. The moving frame moves the wire rod, thereby spreading the coating slurry evenly. Attached Figure Description

[0019] 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.

[0020] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a precision coating thickness adjustment device for a scraper, including a scraper body 1, a placement platform 2 fixedly connected to the outer surface of the scraper body 1, a movable frame 3 sleeved on the outer surface of the placement platform 2, a support rod 4 fixedly connected to the outer surface of the movable frame 3, a holding box 5 sleeved on the outer surface of the support rod 4, a blocking block 11 provided on the inner wall of the holding box 5, a rotating rod 12 sleeved on the inner wall of the blocking block 11, a first knob 13 fixedly connected to one end of the rotating rod 12, a threaded connection between one end of the rotating rod 12 and the inner wall of the holding box 5, a locking block 6 fixedly connected to the outer surface of the holding box 5, a slider 7 provided on one side of the support rod 4, a blocking block 8 fixedly connected to one end of the slider 7, a spring 10 fixedly connected to one side of the blocking block 8, and a limit rod 9 fixedly connected to one side of the blocking block 8.

[0021] In this embodiment, the coating machine body 1 ensures normal coating operation, the placement platform 2 is used to place and fix the material to be coated, the moving frame 3 drives other components to move, thereby performing the coating operation, the support rod 4 ensures that the holding box 5 will not fall during operation, the holding box 5 is used to store the coating slurry required for coating, and the blocking block 11 ensures that the coating slurry inside the holding box 5 will not leak. The rotating rod 12 is rotatably connected to the blocking block 11 and is threadedly connected to the holding box 5. Therefore, when the first knob 13 is turned, the rotating rod 12 is also turned, thereby moving the blocking block 11 from the holding box 5. The bottom of the container 5 is moved to adjust the opening degree of the bottom of the container 5, so that the material can be discharged again after the slurry on the surface of the coating material is scraped off. When installing the container 5, the locking block 6 is engaged with the locking slot to squeeze the blocking block 8, causing the blocking block 8 to move into the support rod 4, thereby driving the limiting rod 9 to slide and compressing the spring 10 at the same time. After the locking block 6 passes the blocking block 8, the spring 10 rebounds and drives the blocking block 8 to reset, so that the blocking block 8 and the locking block 6 are attached to one side, thus fixing the container 5. When the container 5 needs to be removed after the work is finished, the limiting of the container 5 can be released by pulling the slider 7.

[0022] Example 2: As Figures 1-5As shown, a movable plate 14 is provided on one side of the movable frame 3. A wire rod 15 is sleeved on the inner wall of the movable plate 14. A second knob 16 is provided on one side of the movable frame 3. A lead screw 17 is fixedly connected to one side of the second knob 16. A bearing 18 is fixedly connected to one end of the lead screw 17. The bearing 18 is placed inside the movable frame 3. The outer surface of the bearing 18 is fixedly connected to the inner wall of the movable frame 3. A fixing rod 19 is fixedly connected to the outer surface of the movable plate 14. The outer surface of the fixing rod 19 is rotatably connected to the inner wall of the wire rod 15. The outer surface of the lead screw 17 is threadedly connected to one end of the movable plate 14. A sliding groove is opened on one side of the movable frame 3. One end of the movable plate 14 is slidably connected to the sliding groove.

[0023] In this embodiment, when it is necessary to adjust the coating thickness during the scraping process, the second knob 16 is turned to drive the lead screw 17 to rotate inside the bearing 18. Since the lead screw 17 is threadedly connected to the moving plate 14, the moving plate 14 moves inside the slide groove while the lead screw 17 rotates. The movement of the moving plate 14 drives the fixed rod 19 to move, thereby driving the wire bar 15 to move, thus spreading the coating slurry evenly.

[0024] Working principle: like Figures 1-5 As shown, in this utility model, when the operator uses the coating machine body 1 to coat the material, the operator first installs the container 5 on the surface of the support rod 4. By engaging the locking block 6 with the locking slot, the blocking block 8 is pressed, causing the blocking block 8 to move inward towards the support rod 4, thereby driving the limiting rod 9 to slide. At the same time, the spring 10 is compressed. After the locking block 6 passes the blocking block 8, the spring 10 returns the blocking block 8 to its original position, causing the blocking block 8 to adhere to one side of the locking block 6, thus fixing the container 5. Then, the operator pours the coating slurry into the container 5, places the material to be coated on the surface of the placement table 2, and drives the screw conveyor by rotating the second knob 16. The rod 17 rotates inside the bearing 18. Since the lead screw 17 is threadedly connected to the moving plate 14, the rotation of the lead screw 17 drives the moving plate 14 to move inside the slide groove. The movement of the moving plate 14 drives the fixed rod 19 to move, thereby driving the wire rod 15 to move. This adjusts the distance between the wire rod 15 and the coating material to adjust the coating thickness. Then, the movement of the moving frame 3 drives the wire rod 15 to move for coating. During coating, the first knob 13 is turned to drive the rotating rod 12 to rotate and drive the blocking block 11 to move, so that the slurry drips onto the surface of the coating material. When the slurry on the surface of the coating material is used up, the above steps are repeated to continue the leveling work.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
