[0019] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following specifically describes the embodiments of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0022] As Figure 1 and Figure 2 shown, an adjustable die head, characterized in that it includes an upper die 1 and a lower die 2. A slurry outlet gap 3 is formed at the end of the upper die 1 and the lower die 2. The upper die 1 is provided with a plurality of through - holes 4 penetrating the upper die 1. A T - shaped block 5 is arranged at the position of the through - holes 4. A micrometer 6 is horizontally fixed on the upper side of the upper die 1. A rotating block 7 is arranged on one side of the micrometer 6. The rotating block 7 is rotatably arranged on the upper side of the upper die 1 through a rotating shaft. One side of the rotating block 7 abuts against the measuring screw of the micrometer 6, and the other side of the rotating block 7 abuts against the upper side of the T - shaped block 5.

[0023] The micrometer 6 is horizontally arranged, which is convenient to observe the corresponding scale value during use, so as to facilitate adjustment during use. During the adjustment of the micrometer 6, it drives the rotation of the rotating block 7, so that the T - shaped block 5 moves, intercepts the slurry outlet gap 3, and further adjusts the lateral distribution of the flow rate.

[0024] At this time, the T-shaped block 5 moves up and down within the through hole 4. To ensure the normal movement of the T-shaped block 5, in this embodiment, the through hole 4 includes an upper stepped hole 41, a lower stepped hole 42, and a communication hole 434 that connects the upper stepped hole 41 and the lower stepped hole 42. The T-shaped block 5 includes a convex shaft 51 at the end position and a vertical shaft 52. The convex shaft 51 is located in the lower stepped hole 42, and the vertical shaft 52 passes through the communication hole 434 and the upper stepped hole 41. An adjusting nut is fixed on the outer side of the vertical shaft 52, and an elastic member is sleeved on the outer side of the vertical shaft 52. The elastic member is located inside the upper stepped hole 41 on the lower side of the adjusting nut. The adjusting nut is fixed to the vertical shaft 52 by threaded connection, and the elastic member is in a compressed state. In this way, without being acted upon by an external force, the T-shaped block 5 is in the highest position. At this time, by adjusting the position of the adjusting nut, the initial height position of the T-shaped block 5 can be adjusted, thereby controlling the size of the slurry discharge gap 3.

[0025] At this time, the convex shaft 51 of the T-shaped block 5 is located at the bottom position, inside the lower stepped hole 42. In this way, the lower stepped hole 42 abuts against the stepped position of the convex shaft 51, thereby limiting the T-shaped block 5 and restricting the highest position of the T-shaped block 5. At this time, the lower side of the elastic member abuts against the bottom of the upper stepped hole 41, and the stepped surface of the upper stepped hole 41 can limit the lower side of the elastic member, so that the T-shaped block 5 is located at the position of the through hole 4. And when the T-shaped block 5 is acted upon by a downward pressure, it can move downward, and when the pressure is withdrawn, it can move upward under the action of the elastic member, thereby realizing the up and down adjustment of the T-shaped block 5.

[0026] At this time, during the adjustment of the micrometer 6, the measuring screw is in a horizontal state, so it also moves horizontally, while the T-shaped block 5 needs to move up and down. Therefore, it is necessary to convert the horizontal movement into up and down movement through the rotating block 7. In this embodiment, the rotating block 7 is L-shaped, including a first arm 71 and a second arm 72. A rotating hole is provided at the connection between the first arm 71 and the second arm 72, and the rotating hole is rotatably connected to the upper die 1 through a rotating shaft. The measuring screw of the micrometer 6 abuts against the outer side of the first arm 71, and the top of the T-shaped block abuts against the outer side of the second arm 72. At this time, the rotating block 7 is integrally L-shaped, the first arm 71 and the second arm 72 are perpendicularly arranged, and a rotating hole is provided at the connection. The rotating hole is rotatably connected to the upper die 1 through a rotating shaft. At this time, the upper die 1 is provided with a rotating boss, so that the rotating block 7 is rotatably arranged on the upper side of the upper die 1. The measuring screw of the micrometer 6 abuts against the outer side of the first arm 71, and the T-shaped block 5 is located at the lower side position of the second arm 72. In this way, when adjusting the micrometer 6 to make the measuring screw move outward, the measuring screw acts on the rotating block 7, causing the rotating block 7 to move, so that the first arm 71 presses the T-shaped block 5 downward, causing the T-shaped block 5 to move downward, thereby adjusting the size of the slurry gap.

[0027] The rotation of the rotating block 7 is achieved through the first arm 71 and the second arm 72. To prevent the situation of "jamming" during the rotation of the rotating block 7, in this embodiment, arc-shaped protrusions 73 are provided at the contact positions between the outer sides of the first arm 71 and the second arm 72 and the micrometer 6 and the T-shaped block 5 respectively. Further, the top of the T-shaped block 5 is an arc surface. After setting the arc-shaped protrusions 73 and the arc surface, the head of the T-shaped block 5 contacts the arc surface of the rotating block 7 (point-point contact), and the arc surface of the rotating block 7 contacts the plane of the head of the micrometer 6 (point-plane contact). Therefore, both of these contacts have a certain floating flexibility, which can effectively prevent jamming between the T-shaped block 5 and the micrometer 6.

[0028] The micrometer 6 is fixed on the upper side of the upper die 1, and the up-and-down movement of the T-shaped block 5 is adjusted through the rotating block 7. In this embodiment, a fixing plate is provided on the upper side of the upper die 1, and a number of arranged fixing holes are provided on the fixing plate. The fixed sleeve of the micrometer 6 is fixed to the fixing plate at the position of the fixing hole, and the measuring screw of the micrometer 6 passes through the fixing hole. The micrometer 6 is fixed to the fixing plate through the position of the fixed sleeve. In this way, after the measuring screw passes through the fixing hole, it can move normally, thus ensuring the normal use of the micrometer 6.

[0029] At this time, the T-shaped block 5 will move up and down in the through hole 4. To ensure the movement of the T-shaped block 5, a plurality of annular grooves 53 are provided on the outer side of the vertical shaft 52. After the T-shaped shaft is inserted into the through hole 4, the annular grooves 53 are located at the position of the communication hole 434.

[0030] In another embodiment, as Figure 3 shown, the lower die 2 is provided with an adjustment groove 21, which runs through the lower die 2 along the length direction of the lower die 2. The adjustment groove 21 divides the lower die 2 into an adjustment end 22 and a fixed end 23. The adjustment end 22 is close to the outlet end of the slurry discharge gap 3. An adjustment hole 24 leading to the adjustment groove 21 is provided in the fixed end 23 of the lower die 2, and a push-pull rod 25 is inserted through the adjustment hole 24. After passing through the adjustment hole 24, the end of the push-pull rod 25 abuts against the adjustment end 22. At this time, with the adjustment groove 21 provided on the lower die 2, under the action of the push-pull rod 25, the lower die 2 can be deformed at the adjustment end 22, thereby adjusting the size of the outlet end of the slurry discharge gap 3, and thus realizing the size adjustment of the die head.

[0031] At this time, the adjustment groove and the push-pull rod can be used alone or in combination with the rotating block.

[0032] This application also provides an embodiment, a coating machine, which uses the adjustable die head in the above embodiment.

[0033] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0034] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
