Description

Technical Field

[0001] The utility model relates to the field of PVC coated fabric processing equipment, and specifically relates to a uniform coating device for PVC coated fabric. Background Technique

[0002] Coated fabric mainly refers to a fabric coated with a special functional material by a special process on the basis of the fabric, which endows the fabric with special functions, so it is also called a functional coated fabric. Existing coated fabrics are mainly divided into three categories: PVC coating, PU coating, and semi-PU coating according to the different coating materials. In the production of PVC coated fabric, a coating device is required for the coating work of the coating material.

[0003] However, there are still some deficiencies in the current coating device. For example, the drying efficiency of the existing coating device is relatively low, resulting in the phenomenon that the surface of the fabric output by the coating device is prone to the coating not being dry, which is likely to cause a decrease in the uniformity of the coating thickness when the coated fabric is wound, and thus there are certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies, and provides a uniform coating device for PVC coated fabric. Content of the Utility Model

[0005] The purpose of the utility model is to provide a uniform coating device for PVC coated fabric to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A uniform coating device for PVC coated fabric, including a workbench and a partitioned storage tank. A coating box is fixedly installed on the top of the workbench, and fixing plates are symmetrically installed on the left and right sides of the coating box. An auxiliary conveying mechanism is rotatably connected inside the fixing plates. A heat insulation plate is fixedly installed on the inner surface of the coating box. The partitioned storage tank is fixedly installed on the top of the coating box. Feeding hoppers are symmetrically embedded and installed on the front and back of the top of the partitioned storage tank. A feeding pipe is fixedly connected to the outside of the partitioned storage tank, and the other end of the feeding pipe is fixedly connected to a spraying component. An air heating component is fixedly installed on the top of the coating box. A second hollow connecting plate is fixedly connected to the inner surface of the coating box, and drying nozzles are fixedly installed in an array at equal distances on the inner side of the second hollow connecting plate.

[0007] Furthermore, the auxiliary conveying mechanism includes a conveying roller, a connecting shaft, an elastic limiting mechanism, and an arc-shaped protection plate. The connecting shaft is fixedly connected through the inside of the conveying roller. Elastic limiting mechanisms are fixedly installed on the outer surface of the conveying roller at equal distances in a ring shape. The end of the elastic limiting mechanism is fixedly connected to the arc-shaped protection plate.

[0008] Furthermore, the inside of the conveying roller is fixedly connected to the outer surface of the connecting shaft, and the end of the connecting shaft is rotatably connected to the inside of the fixing plate. Moreover, the conveying roller and the fixing plate form a rotating structure through the connecting shaft.

[0009] Furthermore, the end of the elastic limiting mechanism is fixedly connected to the outer surface of the conveying roller, and the other end of the elastic limiting mechanism is fixedly connected to the inner side of the arc-shaped protection plate. Moreover, the arc-shaped protection plate and the conveying roller form an elastic structure through the elastic limiting mechanism.

[0010] Furthermore, the spraying assembly includes a first hollow connecting plate, a fixing rod, and an atomizing nozzle. The fixing rod is fixedly installed on the outer side of the first hollow connecting plate, and the atomizing nozzles are embedded and installed on the inner side of the first hollow connecting plate in an array at equal distances.

[0011] Furthermore, the end of the fixing rod is fixedly connected to the outer side of the first hollow connecting plate, and the other end of the fixing rod is fixedly connected to the inner surface of the coating box. Moreover, the first hollow connecting plate and the coating box form a fixed structure through the fixing rod.

[0012] Furthermore, the air heating assembly includes an air heating box, an exhaust fan, an electric heating grid, and a conveying pipe. The exhaust fans are symmetrically embedded and installed on the front and back sides of the outer side of the air heating box. The electric heating grids are fixedly installed at equal distances inside the air heating box. The conveying pipes are symmetrically installed on the other side of the air heating box. At the same time, the other end of the conveying pipe is fixedly connected to the outer surface of the second hollow connecting plate.

[0013] The utility model provides a uniform coating device for PVC coated fabric, which has the following beneficial effects:

[0014] 1. By arranging the electric heating grid, when the electric heating grid operates, it can automatically perform temperature-raising and heating treatment inside the air heating box. Thus, when the exhaust fan conveys the outside air into the air heating box during operation, the air can be automatically heated. Furthermore, the conveying pipe can evenly convey the heated air to the second hollow connecting plate and blow it onto the outer surface of the coated fabric through the drying nozzles, so as to achieve the purpose of rapid drying. This avoids the situation that the surface of the fabric output by the coating device has wet paint, resulting in a decrease in the uniformity of the paint thickness when the coated fabric is wound. And because the second hollow connecting plate is symmetrically arranged up and down with the vertical bisector of the coating box as the axis of symmetry, the drying nozzles can blow the hot air more comprehensively onto the outer surface of the coated fabric, thereby further improving the drying rate of the device.

[0015] 2. The utility model enables the coated fabric to be always in a completely straightened state when entering the coating box through the arranged auxiliary conveying mechanism, so that the coating sprayed by the spraying assembly during operation can be more evenly attached to the outer surface of the fabric. And through the arranged elastic limiting mechanism and arc-shaped protective plate, the auxiliary conveying mechanism can straighten and convey fabrics with more thicknesses. And because the partitioned storage tank is arranged in a partitioned manner, when the staff needs to spray other coatings, they can quickly switch the coatings by turning on and off the control valves in the corresponding material conveying pipes, thereby further improving the processing efficiency of the staff.

[0022] As Figures 1 - 3As shown in the figure, a coating box 2 is fixedly installed on the top of the workbench 1, and fixing plates 3 are symmetrically installed on the left and right sides of the coating box 2.
