Description

Technical Field

[0001] This utility model relates to the field of automatic flatbed coating machine technology, and in particular to an adjustable die head for an automatic flatbed coating machine. Background Technology

[0002] An automatic flatbed coating machine is an automated device used to uniformly coat a thin film onto the surface of flat substrates. Through a precise mechanical structure and control system, it can uniformly apply liquid materials such as paints and adhesives onto flat surfaces, such as glass, metal plates, and plastic plates, at a set thickness and speed.

[0003] The die head of the automatic flatbed coating machine is one of the key components of the equipment. During the coating test of lithium-ion battery materials, fluid materials such as paint are poured into the material tank of the die head. Then, the automatic flatbed coating machine moves the die head, and the die head uses a scraper to evenly cover the paint onto the surface of the flat substrate, thereby achieving the coating effect required for lithium-ion battery materials.

[0004] The shortcomings of the existing technical solutions are as follows: the currently used automatic flatbed coating machine's die head has significant defects. In terms of adjustment, the material width and thickness are difficult to change flexibly, making it difficult to adapt to the diverse coating specifications required by different testing scenarios. When performing double-sided coating operations, it cannot precisely adjust the thickness of the coating on both sides. Taking lithium-ion battery material testing as an example, some material specifications have specific requirements for coating width, and due to the limitations of the die head, it is often necessary to replace the entire die head equipment. This process is complex, consumes a lot of time and manpower, reduces testing efficiency, and easily affects the accuracy of test results. Utility Model Content

[0005] This invention provides an adjustable die head for an automatic flatbed coating machine, which can solve the problem in the prior art that the die head equipment is difficult to flexibly change the material width and thickness.

[0006] An adjustable die head for an automatic flatbed coating machine includes a crossbeam, with side plates fixedly arranged on both sides of the crossbeam. A scraper is fitted between two sets of side plates. A thickness adjustment component for adjusting the thickness of the material layer on the scraper is provided on the crossbeam. Each set of side plates is provided with an adjustment plate for limiting the width of the material layer, and a width adjustment component for adjusting the position of the adjustment plate.

[0007] As a further embodiment of this utility model: each set of width adjustment components includes a first coarse adjustment cylinder that is threadedly connected to the side plate, and a first fine adjustment rod is threadedly connected inside the first coarse adjustment cylinder. A first connecting shaft is fixedly provided on one side of each set of adjustment plates. Each set of first connecting shafts is rotatably connected to the corresponding first fine adjustment rod. The thread density between the first fine adjustment rod and the first coarse adjustment cylinder is greater than the thread density between the first coarse adjustment cylinder and the side plate.

[0008] As a further embodiment of this utility model: the thickness adjustment assembly includes a second coarse adjustment cylinder threadedly connected to the crossbeam, a second fine adjustment rod threadedly connected inside the second coarse adjustment cylinder, a second connecting shaft fixedly mounted on the scraper, the second connecting shaft being rotatably connected to the second fine adjustment rod, and the thread density between the second fine adjustment rod and the second coarse adjustment cylinder being greater than the thread density between the second coarse adjustment cylinder and the crossbeam.

[0009] As a further embodiment of this utility model: the first connecting shaft is provided with a width adjustment range.

[0010] As a further embodiment of this utility model, the second connecting shaft is provided with a height adjustment range.

[0011] As a further embodiment of this utility model: both sets of side plates are fixedly provided with slide rails for maintaining the stability of the adjustment plate.

[0012] As a further embodiment of this utility model: the ends of the first and second thin adjusting rods are both coaxially provided with knobs that facilitate rotation by the operator.

[0013] As a further embodiment of this utility model: the thickness adjustment components are provided in two sets, and both are symmetrically arranged on both sides of the crossbeam.

[0014] As a further embodiment of this utility model: the rear side of the adjustment plate is in contact with the front side of the scraper.

[0015] As a further embodiment of this utility model, positioning elements are provided on the outer sides of both sets of side plates.

[0016] The beneficial effects of this utility model are:

[0017] 1. When adjusting the width of the material layer, the operator can first rotate the first coarse adjusting cylinder on both side plates, causing the adjusting plate to move laterally by a certain range, achieving a coarse adjustment effect. Then, as needed, the first fine adjusting rod is rotated. Because the thread density of the first fine adjusting rod is greater than the thread density of the fit between the first coarse adjusting cylinder and the side plates, the first fine adjusting rod will produce a finer lateral movement when rotating within the first coarse adjusting cylinder. This fine movement can drive the adjusting plate to move laterally, achieving more precise lateral adjustment to meet different testing and production requirements.

[0018] 2. When adjusting the material layer thickness, the operator can first rotate the second coarse adjustment cylinder to move the scraper longitudinally, achieving a coarse adjustment effect. Then, as needed, the second fine adjustment rod can be rotated. Because the thread density of the second fine adjustment rod is greater than the thread density of the second coarse adjustment cylinder and the crossbeam, the second fine adjustment rod will make a more precise longitudinal movement, finely adjusting the scraper position, changing the distance between the scraper and the coating substrate, thereby accurately controlling the material layer thickness and ensuring the consistency and stability of the material layer.

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0025] like Figures 1 to 3 As shown in the figure, an adjustable die head for an automatic flatbed coating machine provided by this utility model includes a crossbeam 1, which serves as the support structure for the entire die head. Side plates 2 are fixedly arranged on both sides of the crossbeam 1, with the two sets of side plates 2 arranged parallel and symmetrically. A scraper 5 is fitted between the two sets of side plates 2. To adjust the thickness of the material layer formed by the scraper 5, a thickness adjustment component 6 is provided on the crossbeam 1. This component can precisely control the lifting height of the scraper 5, thereby controlling the thickness of the material layer. Simultaneously, each set of side plates 2 is provided with an adjustment plate 3 for limiting the width of the material layer, and a width adjustment component 4 for adjusting the position of the adjustment plate 3. By adjusting the position of the adjustment plate 3, the width of the material layer can be changed, thereby adapting to different testing and production requirements.

[0026] The scraper 5 features flexible height adjustment, a function achieved through precise control of the thickness adjustment component 6. Adjusting the height of the scraper 5 effectively controls the material layer thickness, ensuring its consistency and stability. The two sets of adjustment plates 3 can flexibly adjust the width of the material layer according to actual needs. By adjusting the width adjustment component 4, the adjustment plates 3 can move laterally, thus changing the width of the material layer. An adjustable material trough 8 is formed in the area between the two sets of adjustment plates 3 and on the front side of the scraper 5. The width of the adjustable material trough 8 can be precisely controlled by the adjustment component, enabling flexible adjustment of both the width and thickness of the material layer.

[0027] Specifically, each width adjustment assembly 4 includes a first coarse adjustment cylinder 401 threadedly connected to the side plate 2. The first coarse adjustment cylinder 401, as the main adjustment component, has external threads that mate with threaded holes on the side plate 2 to achieve a threaded connection. A first fine adjustment rod 402 is threadedly connected inside the first coarse adjustment cylinder 401. The thread density of the first fine adjustment rod 402 is greater than the thread density between the first coarse adjustment cylinder 401 and the side plate 2, allowing for more precise lateral movement of the first fine adjustment rod 402 when the first coarse adjustment cylinder 401 is rotated. A first connecting shaft 403 is fixedly mounted on one side of each adjustment plate 3, and each first connecting shaft 403 is rotatably connected to a corresponding first fine adjustment rod 402. Thus, when the first coarse adjustment cylinder 401 is rotated, it can drive the first fine adjustment rod 402 to move laterally, thereby driving the first connecting shaft 403 and the adjustment plate 3 to move laterally, thus adapting to the required width of the material layer.

[0028] The thickness adjustment component 6 has a similar structure and working principle to the width adjustment component 4. It includes a second coarse adjustment cylinder 601 threadedly connected to the crossbeam 1, with a second fine adjustment rod 602 threadedly connected inside the second coarse adjustment cylinder 601. A second connecting shaft 603 is fixedly mounted on the scraper 5, and the second connecting shaft 603 is rotatably connected to the second fine adjustment rod 602. Similarly, the thread density between the second fine adjustment rod 602 and the second coarse adjustment cylinder 601 is greater than the thread density between the second coarse adjustment cylinder 601 and the crossbeam 1. In use, rotating the second coarse adjustment cylinder 601 causes it to be screwed out or into the crossbeam 1, thereby causing the second fine adjustment rod 602 to move laterally, which in turn causes the second connecting shaft 603 and the scraper 5 to move longitudinally, thus adjusting the height of the scraper 5 to suit the required thickness of the material layer.

[0029] In this embodiment, to facilitate adjustment operations, knobs are coaxially provided at the ends of both the first fine adjustment rod 402 and the second fine adjustment rod 602. The design of these knobs allows operators to easily rotate the fine adjustment rods, thereby achieving precise adjustments, improving the user experience, and making the adjustment process more convenient and efficient.

[0030] Furthermore, to allow for precise adjustment of thickness and width during use, the first connecting shaft 403 is equipped with a width adjustment range, and the second connecting shaft 603 is equipped with a height adjustment range. These range markings allow operators to clearly understand the current adjustment status and make precise adjustments as needed. In addition, slide rails 7 are fixedly installed on both sets of side plates 2 to maintain the stability of the adjusting plate 3. The design of these slide rails 7 prevents the scraper 5 from shifting laterally during movement or scraping, thus avoiding material leakage from the adjustable trough 8. Simultaneously, the rear side of the adjusting plate 3 fits snugly against the front side of the scraper 5; this tight fit effectively confines the material within the adjustable trough 8, ensuring the stability of the material layer.

[0031] In one specific embodiment, to improve the stability of adjustment, two sets of thickness adjustment components 6 can be provided, both symmetrically arranged on both sides of the crossbeam 1. During adjustment, the operator can adjust both sets of thickness adjustment components 6 simultaneously, ensuring that the scraper 5 remains stable during lifting and lowering, and preventing it from tilting to one side. This symmetrical design not only improves the accuracy of adjustment but also enhances the stability of the entire die head.

[0032] In another specific embodiment, in order to fix the overall die head and facilitate the lateral movement of the die head by the automatic flatbed coating machine, positioning elements are provided on the outer sides of both sets of side plates 2. These positioning elements can be threaded grooves formed on the side plates 2, or they can be clamping elements or magnetic suction elements, etc. Regardless of the form of the positioning elements used, their purpose is to ensure the stability of the die head on the automatic flatbed coating machine. The design of these positioning elements all fall within the protection scope of this patent.

[0033] Working Principle: When adjusting the material layer width, the operator first rotates the first coarse adjusting cylinder 401 on both side plates 2, causing the adjusting plate 3 to move laterally by a certain range, achieving a coarse adjustment effect. Then, as needed, the first fine adjusting rod 402 is rotated. Because the thread density of the first fine adjusting rod 402 is greater than the thread density of the first coarse adjusting cylinder 401 mating with the side plate 2, the first fine adjusting rod 402 produces a finer lateral movement when rotating within the first coarse adjusting cylinder 401. This fine movement can drive the adjusting plate 3 to move laterally, achieving finer lateral adjustment to meet different testing and production requirements.

[0034] Regarding the adjustment of the coating thickness, the operator first rotates the second coarse adjustment cylinder 601, causing the scraper 5 to move longitudinally, achieving a coarse adjustment effect. Then, as needed, the operator rotates the second fine adjustment rod 602. Because the thread density of the second fine adjustment rod 602 is greater than the thread density of the coarse adjustment cylinder 601 and the crossbeam 1, the second fine adjustment rod 602 will make a more precise longitudinal movement, finely adjusting the position of the scraper 5, changing the distance between the scraper 5 and the coating substrate, thereby accurately controlling the coating thickness and ensuring the consistency and stability of the coating layer.

[0035] The first connecting shaft 403 and the second connecting shaft 603 are respectively equipped with width adjustment range and height adjustment range, which makes it convenient for operators to understand the adjustment status and make precise adjustments. The slide rails 7 on the two side plates 2 maintain the stability of the adjustment plate 3, and the adjustment plate 3 fits tightly with the scraper 5 to prevent material from leaking out of the adjustable trough 8.

[0036] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
