Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a die head displacement adjustment structure in a coating machine. Background Technology

[0002] In a coating machine, the coating thickness is adjusted by moving the die head relative to the steel roller. The die head needs to move away from or closer to the steel roller. This is to facilitate coating thickness adjustment during the coating process and to have a large stroke to facilitate cleaning of the steel roller.

[0003] In existing adjustment methods, a rotating lead screw and a scale are integrated at both ends of the die head. The relative distance is adjusted by rotating the lead screw. Although the adjustment accuracy is high, the response efficiency is low. Therefore, it is necessary to perform rapid position adjustment of the die head to improve the adjustment efficiency and accuracy. Utility Model Content

[0004] (I) Technical Issues

[0005] The purpose of this invention is to provide a die head displacement adjustment structure in a coating machine, which solves the problem of quickly adjusting the relative position of the die head to improve adjustment efficiency and accuracy.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A die head displacement adjustment structure for a coating machine includes a base and multiple support blocks spaced apart on the base. Sliding guide rails are mounted on the support blocks, and mounting plates are slidably mounted on the multiple sliding guide rails. A die head is fixedly mounted on the mounting plates. A large-stroke cylinder is rotatably mounted on the base, and the telescopic rod of the large-stroke cylinder is rotatably connected to the mounting plates. A small-stroke cylinder is fixedly mounted on the base, and the telescopic rod of the small-stroke cylinder is fixedly connected to the mounting plates.

[0009] Preferably, the end of the lifting rod of the long-stroke cylinder is rotatably connected to a first pin, a first mounting block is mounted on the first pin, and the first mounting block is fixed to the bottom of the mounting plate; a second pin is mounted on the base, and a connecting seat is mounted on the end of the long-stroke cylinder, the connecting seat being rotatably mounted on the second pin.

[0010] Preferably, a mounting base is installed on the base, the short-stroke cylinder is fixedly installed on the mounting base, and a second mounting block is provided on the telescopic rod of the short-stroke cylinder, the second mounting block being fixed to the bottom of the mounting plate.

[0011] Preferably, a limiting rod is fixed on the second mounting block, and the limiting rod is provided with a threaded sleeve that is threadedly engaged with it; the end of the limiting rod extends toward the mounting base.

[0012] Preferably, the end of the support block is provided with an upwardly extending limiting portion.

[0013] Preferably, the base has a limiting groove, and the support block is installed in the limiting groove.

[0014] Preferably, there are two large-stroke cylinders and two small-stroke cylinders, with each small-stroke cylinder located on one side of an adjacent large-stroke cylinder.

[0015] (III) Beneficial Effects

[0016] By rotating a large-stroke cylinder between the base and the mounting plate, and simultaneously fixing a small-stroke cylinder, the large-stroke cylinder quickly pulls the mounting plate to move its position relative to the sliding guide rail, while the small-stroke cylinder provides final control over the specific movement stroke. This allows for rapid adjustment of the mounting plate's position. The die head, mounted on the mounting plate, can also be quickly adjusted relative to the steel roller.

[0017] Meanwhile, the large-stroke cylinder's rapid adjustment is limited by the buffering effect of the small-stroke cylinder. Therefore, a two-stage adjustment method is achieved: in the stage of large adjustment distance (rapid adjustment), the large-stroke cylinder plays a dominant role, while the small-stroke cylinder acts as a buffer; in the stage of small adjustment distance (precise adjustment), the small-stroke cylinder plays a dominant role, while the large-stroke cylinder acts as a buffer. This allows for speed differences in mold head adjustment between the rapid and precise adjustment stages, effectively improving adjustment efficiency while maintaining accuracy.

[0025] 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.

[0026] See Figures 1-5 As shown in the embodiment of this utility model, a displacement adjustment structure for a die head 5 in a coating machine is proposed. The coating machine is used to realize processes such as slurry feeding and coating. The coating thickness is adjusted by adjusting the distance between the die head 5 and the steel roller, or to facilitate cleaning of the steel roller. Therefore, it is necessary to quickly adjust the die head 5 relative to the steel roller when it moves away from or closer to it. Specifically, it includes a base 1 and multiple support blocks 2 spaced apart on the base 1. A sliding guide rail 3 is installed on the support block 2, and an mounting plate 4 is slidably installed on the multiple sliding guide rails 3. The die head 5 is fixedly installed on the mounting plate 4, so that the die head 5 can slide relative to the base 1 along with the mounting plate 4 and is supported by the support blocks 2. The sliding guide rail 3 ensures that the mounting plate 4 can slide stably when it slides, especially ensuring that the positional difference of the die head 5 before and after movement is small.

[0027] To improve sliding and support reliability, three support blocks 2 are spaced apart and evenly distributed along the length of the mounting plate 4. Simultaneously, a limiting groove 15 is formed on the base 1, and the support blocks 2 are installed within the limiting groove 15. This ensures the limiting effect of the support blocks 2 after installation within the limiting groove 15, and also determines the relative installation position of the support blocks 2.

[0028] Meanwhile, a large-stroke cylinder 6 is rotatably mounted on the base 1, and the telescopic rod of the large-stroke cylinder 6 is rotatably connected to the mounting plate 4. A small-stroke cylinder 7 is fixedly mounted on the base 1, and the telescopic rod of the small-stroke cylinder 7 is fixedly connected to the mounting plate 4. The small-stroke cylinder 7 is fixed relative to the base 1 and the mounting plate 4, while the large-stroke cylinder 6 is rotatably mounted relative to the base 1 and the mounting plate 4. Thus, during the larger stroke phase, the large-stroke cylinder 6 quickly drives the mounting plate 4 to slide relative to the base 1, at which point the small-stroke cylinder 7 acts as a buffer. During the smaller stroke phase, the small-stroke cylinder 7 controls the accurate movement of the mounting plate 4, at which point the large-stroke cylinder 6 acts as a buffer. This achieves two-stage adjustment, enabling rapid adjustment while meeting the needs of flexible adjustment, thereby improving adjustment efficiency while ensuring accuracy.

[0029] Specifically, a first pin 8 is rotatably connected to the end of the lifting rod of the large-stroke cylinder 6, and a first mounting block 10 is installed on the first pin 8. The first mounting block 10 is fixed to the bottom of the mounting plate 4. A second pin 9 is installed on the base 1, and a connecting seat 11 is installed at the end of the large-stroke cylinder 6. The connecting seat 11 is rotatably installed on the second pin 9. The large-stroke cylinder 6 is rotatably connected between the base 1 and the mounting plate 4 through the first pin 8 and the second pin 9.

[0030] An mounting base 12 is installed on the base 1, and the small-stroke cylinder 7 is fixedly installed on the mounting base 12. A second mounting block 13 is provided on the telescopic rod of the small-stroke cylinder 7. The second mounting block 13 is fixed to the bottom of the mounting plate 4 to achieve fixed installation of the small-stroke cylinder 7.

[0031] It should be noted that the extension limit of the small-stroke cylinder 7 is less than that of the large-stroke cylinder 6. The small-stroke cylinder 7 is installed on one side of the middle position of the large-stroke cylinder 6. This ensures that the actual distance that the large-stroke cylinder 6 can push the mounting plate 4 is less than the actual distance that the small-stroke cylinder 7 can push the mounting plate 4. This avoids the risk of the large-stroke cylinder 6 causing the small-stroke cylinder 7 to overtravel and be damaged.

[0032] Specifically, in order to limit the minimum gap between the die head 5 and the steel roller after the relative position is adjusted, a limiting rod 16 is fixed on the second mounting block 13. The limiting rod 16 is provided with a threaded sleeve 17 that is threadedly engaged with it. The end of the limiting rod 16 extends toward the mounting base 12. By adjusting the length of the limiting rod 16 extending toward the mounting base 12 and locking it with the threaded sleeve 17, the minimum gap can be adjusted. After the limiting rod 16 abuts against the mounting base 12, the limit position of the adjustment state is limited.

[0033] Meanwhile, an upwardly extending limiting part 14 is provided at the end of the support block 2, which limits the sliding limit position of the mounting plate 4.

[0034] Specifically, to ensure stability when the mounting plate 4 is driven to slide relative to each other, there are two large-stroke cylinders 6 and two small-stroke cylinders 7, with each small-stroke cylinder 7 located on one side of an adjacent large-stroke cylinder 6. This ensures smoothness when pushing or pulling the mounting plate 4.
