Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to a height adjustment mechanism for a coating head. Background Technology

[0002] Coating machines are mainly used for surface coating processes on substrates such as films and paper. The coating material is supplied from the storage container to the coating head or roller through the supply system. Then, the coating head or roller evenly coats the coating material with a layer of liquid, slurry or other material, thereby completing the coating operation.

[0003] The existing technology (Chinese patent announcement number: CN220825027U, announcement date: 2024-04-23) discloses a double-layer slit coating head, which has an injection channel for conveying adhesive to the dispensing channel on both the lower and middle molds of the coating head body, thus providing a structure with two injection channels. This effectively separates the coating material or adhesive into layers, resulting in a thinner coating layer. Compared to a single-layer coating head, it reduces material waste while maintaining coating effect. The distance between the coating head body and the coating roller can be adjusted according to requirements via an adjustment component, making it convenient to use and highly efficient.

[0004] While existing technologies can adjust the distance between the coating head body and the coating roller, they cannot adjust the height of the coating head. A coating head with a fixed height cannot meet the needs of different coating processes during operation. Furthermore, the stability of the coating head is poor when it is adjusted, which may cause the position of the coating head to be unstable and affect subsequent coating operations.

[0005] Therefore, we propose a height adjustment mechanism for the coating head to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a height adjustment mechanism for a coating head, in order to solve the problems mentioned in the background art, which are unable to adjust the height of the coating head, and the fixed height of the coating head cannot meet the needs of different coatings during operation. At the same time, the stability of the coating head is poor when adjusting it, which may make the position adjustment of the coating head unstable and affect subsequent coating operations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a height adjustment mechanism for a coating head, comprising a coating head body, an overflow groove on the inner side of the coating head body, and a glue injection tube for feeding glue onto the rear side of the coating head body. A support leg assembly consisting of an adjusting column and a fixed column is provided on the lower surface of the coating head body, and a height adjustment mechanism is provided between the support leg assemblies. The height adjustment mechanism adjusts the height of the coating head body through the threaded connection between the threaded sleeve and the threaded rod provided on the inner side.

[0008] Furthermore, the adjusting support is fixedly connected to the lower surface of the coating head body, and a fixed support is nested on the outside of the adjusting support, and a fixed plate is fixedly connected between the two sets of fixed supports.

[0009] Furthermore, the height adjustment mechanism includes an adjusting worm gear, which is nested and connected to the center of the fixed plate. A threaded rod is fixedly connected to the upper end of the adjusting worm gear, and a threaded sleeve is threadedly connected to the outer side of the threaded rod. An abutment plate is fixedly connected to the upper end of the threaded sleeve, and the upper surface of the abutment plate is fixedly connected to the lower surface of the coating head body.

[0010] Furthermore, the threaded sleeve and the threaded rod constitute a sliding mechanism, the adjusting support column forms a sliding structure with the coating head body and the fixed support column, and the contact plate is located at the center of the lower surface of the coating head body.

[0011] Furthermore, a fixed shaft is nested on the upper surface of the fixed plate, and a gear is fixedly connected to the outer side of the center of the fixed shaft. A rotating rod is fixedly connected to the outer end of the fixed shaft, and an abutment groove is provided inside the rotating rod.

[0012] Furthermore, the gears mesh with the adjusting worm, and two sets of gears are symmetrically arranged about the left and right sides of the adjusting worm. The fixed shaft forms a rotating structure with the fixed plate through the gears.

[0013] Furthermore, the fixed support column has an adjustment groove on its side, and the lower end of the adjustment support column is fixedly connected to an abutment rod, which is nested inside the abutment groove. The abutment rod and the abutment groove form a sliding structure through a rotating rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The coating is injected into the overflow tank through the glue injection tube located on the rear side of the coating head body, so that the coating head body comes into contact with the part to be coated, thus completing the coating operation. The height of the coating head body can be adjusted by adjusting the sliding of the support column inside the fixed support column, so that the height of the coating head body can be adapted to different operation requirements and improve the adaptability of the device.

[0016] 2. Rotate the adjusting worm. At this time, the adjusting worm can synchronously drive the adjusting worm set above to rotate. When the adjusting worm rotates, it can synchronously drive the threaded sleeve to move through the threaded connection. At this time, the threaded sleeve can drive the coating head body to move in position through the contact plate fixedly connected to the coating head body at the upper end, thereby causing the coating head body to change in height.

[0017] 3. As the coating head body moves up and down, causing height changes, the adjusting support pillars on the side of the coating head body slide up and down along the inner side of the fixed support pillars. The sliding connection between the adjusting support pillars and the fixed support pillars can improve the stability of the coating head body's movement and the stability of the coating head body's height adjustment.

[0018] 4. When the adjusting worm rotates, it can synchronously drive the gear meshing with it to rotate. At this time, the gear can drive the fixed shaft to rotate synchronously, so that the fixed shaft drives the rotating rods set at both ends to rotate synchronously. At this time, the abutting groove set on the inner side of the rotating rod can abut against the abutting rod set at the lower end of the adjusting support, thereby further driving the adjusting support to move up and down through the abutting rod, so that the adjusting support can synchronously drive the coating head body to move up and down.

[0019] 5. The height of the coating head body is adjusted at the middle position by the fixing plate and at the corner of the coating head body by the rotating rod. This dual adjustment method further improves the stability of the coating head body during height adjustment, allowing the coating head body to perform subsequent coating operations better.

[0028] Example 1: As Figure 1 and Figure 2 The present invention provides the following technical solution: a height adjustment mechanism for a coating head, comprising a support leg assembly, wherein the height of the coating head body 1 can be adjusted by adjusting the position of the support leg assembly; an overflow groove 2 is provided on the inner side of the coating head body 1, and a glue injection tube 3 for feeding material is provided on the rear side of the coating head body 1; a support leg assembly consisting of an adjusting column 4 and a fixed column 5 is provided on the lower surface of the coating head body 1; a height adjustment mechanism is provided between the support leg assemblies; the height adjustment mechanism adjusts the height of the coating head body 1 by the threaded connection between the threaded sleeve 10 and the threaded rod 9 provided on the inner side; the adjusting column 4 is fixedly connected to the lower surface of the coating head body 1, and a fixed column 5 is nested on the outer side of the adjusting column 4; and a fixed plate 6 is fixedly connected between the two sets of fixed columns 5.

[0029] Paint is injected into the overflow tank 2 through the glue injection tube 3 located on the rear side of the coating head body 1, making the coating head body 1 contact the part to be coated and completing the coating operation. The height of the coating head body 1 is adjusted by the sliding of the adjusting support 4 inside the fixed support 5. As the coating head body 1 moves up and down, the adjusting support 4 located on the side of the coating head body 1 slides up and down along the inner side of the fixed support 5. The sliding connection between the adjusting support 4 and the fixed support 5 can improve the stability of the movement of the coating head body 1 and the stability of the height adjustment of the coating head body 1, so that the height of the coating head body 1 can adapt to different operation requirements and improve the adaptability of the device. The height can be adjusted at the middle position of the coating head body 1 by the fixed plate 6 and at the corner of the coating head body 1 by the rotating rod 14. The dual adjustment method further improves the stability of the height adjustment of the coating head body 1, so that the coating head body 1 can better perform subsequent coating operations.

[0030] Example 2: Figure 3 and Figure 4 The technical solution shown is provided by the present invention as follows: A height adjustment mechanism for a coating head is disclosed, which can drive the coating head body 1 to adjust its height.

The threaded sleeve 10 and the threaded rod 9 form a sliding mechanism. The adjusting support column 4 forms a sliding structure through the coating head body 1 and the fixed support column 5. The abutment plate 11 is located at the center of the lower surface of the coating head body 1.

[0031] Rotate the adjusting worm 7. At this time, the adjusting worm 7 can drive the upper adjusting worm 7 to rotate synchronously. When the adjusting worm 7 rotates, it can drive the threaded sleeve 10 to move synchronously through the threaded connection. At this time, the threaded sleeve 10 can drive the coating head body 1 to move in position through the contact plate 11 fixedly connected to the upper end of the coating head body 1, thereby causing the coating head body 1 to change in height.

A fixed shaft 13 is nested on the upper surface of the fixed plate 6, and a gear 8 is fixedly connected to the outer side of the center of the fixed shaft 13. The rotating rod 14 is fixedly connected to the outer end of the fixed shaft 13. At the same time, an abutment groove 16 is opened inside the rotating rod 14. The gear 8 and the adjusting worm 7 mesh with each other, and two sets of gears 8 are symmetrically arranged about the left and right sides of the adjusting worm 7. The fixed shaft 13 forms a rotating structure with the fixed plate 6 through the gear 8. An adjusting groove 12 is opened on the side of the fixed support column 5.

[0033] When the adjusting worm 7 rotates, it can synchronously drive the gear 8 that meshes with it to rotate. At this time, the gear 8 can drive the fixed shaft 13 to rotate synchronously, so that the fixed shaft 13 drives the rotating rods 14 set at both ends to rotate synchronously. At this time, the abutting groove 16 set on the inner side of the rotating rod 14 can abut against the abutting rod 15 set at the lower end of the adjusting support 4, thereby further driving the adjusting support 4 to move up and down through the abutting rod 15, so that the adjusting support 4 can synchronously drive the coating head body 1 to move up and down.
