Agricultural membrane functional liquid coating drying device

Technical field

The invention belongs to the technical field of agricultural film production equipment, and particularly relates to an agricultural film functional liquid coating drying device.

Background technique

In order to improve the physicochemical properties of the agricultural film, the agricultural film is usually introduced into the functional liquid immersion tank after the agricultural film is extruded, so as to apply some liquid with improved function on the surface of the agricultural film (also called "Functional fluid"), these functional liquids are solidified to form a functional coating. Common functional fluids include anti-drip solution, anti-fogging agent, anti-aging agent, and the like. In order to dry the surface of the agricultural film coated with the functional liquid before the winding, the existing agricultural film functional liquid coating drying device also has two left and right scraping rollers above the dip coating tank, and the vertical position of the left and right scraping rollers Staggered, two left and right air knives are symmetrically arranged above and below the two scraping rollers, and each wind knives is provided with a long slit-shaped wind knife edge.

However, the drying effect of the existing agricultural film functional liquid coating drying device is not ideal, and some even need to be dried by the oven to wind up, which mainly has the following reasons: 1. If the air knife blows out the wind speed Larger, it is easy to cause the film to disorderly swing to the left and right, affecting the winding quality; if the wind knife edge is too close to the film, it may also cause the wind knife to scratch the film due to the large swing of the film, so the existing blow drying device wind The wind speed blown by the knife is only controlled to be small, and it has to leave the film for a long distance, so the drying effect is not ideal. 2. For different thickness, material and running speed film, the ideal blowing angle is different. However, the blow angle of the existing air knife is difficult to fine-tune, and it is not suitable for different thickness, material, and running speed of the film for different requirements of the blowing angle.

Summary of the invention

The object of the present invention is to overcome the above disadvantages and provide an agricultural film functional liquid coating drying device, which can enhance the film drying effect, and avoid the wind knife edge scratching the film, and reduce the film disorderly and irregularly swinging left and right.

Each air knife is provided with a mounting bracket, wherein each air knife is further provided with a longitudinal rotating shaft, and the longitudinal rotating shaft is mounted on a mounting bracket corresponding to the air knife, and each air knife can rotate around the respective longitudinal shaft Swinging; a horizontal rail is disposed under each of the mounting brackets, and the mounting brackets of the air knives are slidably mounted on the corresponding lateral rails; each air knife is further provided with a stable guide near the wind knife edge Roller, the axial direction of the stabilizing guide roller is parallel to the axial direction of the scraping roller, and each of the front and rear ends of the stabilizing guide roller is provided with a stable guide roller support, and the two stable guide roller supports of each stable guide roller are fixedly connected and installed in the corresponding At the front and rear ends of the air knife, when the air knife swings around the longitudinal axis, the corresponding stable guide roller also oscillates around the longitudinal axis; each of the stable guide rollers is provided with a guide roller shaft, and the stable guide roller can rotate around the guide roller shaft, and the guide roller shaft Fixed connection with stable guide roller support Rotating, magnetic blocks are fixedly embedded in the middle of the guide roller shaft of each of the stable guide rollers, and the magnetic blocks of the two guide roller shafts are attracted to each other; the mounting bracket of the left air knife is fixedly connected with the left rack The mounting bracket of the right air knife is fixedly connected with the right rack, the left rack is meshed with the left gear, the right rack is meshed with the right gear, and the right gear is equal in size and directly meshed with the left gear, the right gear or the left gear The handle has a handle that controls its rotation.

In the present application, the horizontal direction indicated by the center axis of the scraping roller is the front-rear direction, the front-rear direction is the longitudinal direction, and the lateral direction refers to the left-right direction, that is, the horizontal direction perpendicular to the longitudinal direction.

The invention has the following advantages and effects:

1. In the working of the present invention, the functional liquid coating on the surface of the agricultural film is firstly shaved by two left and right scraping rolls, after which the agricultural film runs through two air knives, and the air knife edges of the two air knives are symmetrically blown to the film, and The stabilizing guide rollers next to the two air knife edges are mutually attracted to automatically clamp the film, so that the air knife edge can be safely placed close to the film, and the film can be stably operated, and the film does not swing greatly to the left and right due to the blowing. Increase the wind speed of blowing, enhance the drying effect of the film, and avoid scratching the film by the wind knife edge.

Second, the air blower angle can be adjusted, can adapt to different thickness, material, running speed of the film for different requirements of the blowing angle, and regardless of the angular position of the wind knife edge adjustment, the stable guide roller naturally follows the wind knife edge.

Third, because the two stable guide rollers are automatically spliced together by the magnet suction force, the operation process of adjusting the air knife edge blowing angle becomes very clever and simple, as follows: just turn the handle to make the right gear and the left gear reverse Rotating, so that the right rack and the left rack move in the opposite direction (the amount of movement is the same), the two mounting brackets are synchronously moved in the opposite direction (the amount of movement is the same), and the two stable guide rollers are affected by the suction of the magnet. Automatically keep the suction close together, the result of the above-mentioned various factors is combined, so that the left and right air knives will automatically swing around their respective longitudinal axes, and the left and right air knives swing oppositely to achieve the wind blade mouth blowing angle adjustment, in addition, the left and right The air knife swing amount is automatically kept equal, so no matter what angle is adjusted, the two air blades automatically remain symmetrical, and the wind direction blown by the two air knives will be symmetrical, which is beneficial to ensure stable operation of the film; in addition, during the adjustment of the blowing angle and After adjustment, the clamping force between the two stable guide rollers is automatically kept substantially constant, that is, approximately equal to the magnet suction force, and After adjustment, the magnet will automatically tighten the left and right two stable guide rollers to fix their relative positions without any additional clamping or clamping action, and no need to adjust the clamping force, so the operation is simple.
