Description

Technical Field

[0001] This utility model provides a multi-angle nozzle assembly, and particularly relates to a multi-angle nozzle assembly for a synthetic leather spraying device. Background Technology

[0002] Synthetic leather spraying equipment is used to uniformly spray coatings, adhesives, and other substances onto the surface of synthetic leather. Its core component, the spray nozzle assembly, is responsible for accurately and stably delivering the material to be sprayed onto the synthetic leather surface, directly affecting the surface quality and production efficiency. The performance of the spray nozzle assembly is paramount in the synthetic leather production process, determining the uniformity of the spray, the coverage area, and the overall production pace.

[0003] Existing synthetic leather spraying equipment typically consists of a single nozzle body and a fixed mounting structure. The nozzle body is usually fixed to a single plane or specific position on the mounting base via simple connectors. The mounting positions on the base are relatively fixed and at a single angle, lacking effective angle adjustment components. This makes it difficult to flexibly adjust the spraying angle of the nozzle according to the size, shape, and actual spraying requirements of the synthetic leather. This structure limits the spraying coverage area and easily creates spraying dead zones. For some irregularly shaped or large-format synthetic leathers, it is often necessary to adjust the position of the synthetic leather multiple times or increase the number of nozzles to achieve full spraying. This is not only cumbersome to operate but also affects product quality due to uneven spraying, thus reducing overall spraying efficiency and failing to meet the needs of efficient and precise synthetic leather production. Utility Model Content

[0004] In order to solve the above problems, this application provides a multi-angle nozzle assembly for a synthetic leather spraying device, which solves the problems of limited spraying angle and dead angles, achieves comprehensive and uniform spraying, reduces operation steps, and improves spraying efficiency and synthetic leather product quality.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-angle nozzle assembly for a synthetic leather spraying device, comprising a polygonal box-shaped mounting base and multiple nozzle assemblies; the mounting base has multiple circular mounting holes, and each nozzle assembly is installed at a different mounting hole, with the multiple mounting holes distributed at multiple angles on the mounting base to achieve multi-angle installation of the nozzle assemblies; each nozzle assembly includes a nozzle body, a connecting shaft, and an adjusting component for adjusting the angle of the nozzle body, the nozzle body being connected to the mounting hole of the mounting base via the connecting shaft, and the adjusting component cooperating with the connecting shaft to adjust the angle of the nozzle body.

[0006] Preferably, the nozzle body is a cylindrical structure with external threads, and the front end of the nozzle body is provided with a nozzle, the edge of which is serrated.

[0007] Preferably, one end of the connecting shaft is fixedly connected to the nozzle body, and the other end is connected to the adjusting component.

[0008] Preferably, the adjusting component includes a flat adjusting plate and a guide plate structure. The adjusting plate is connected to the connecting shaft, and the guide plate structure is disposed on the side of the connection between the adjusting plate and the connecting shaft.

[0009] Preferably, the guide plate structure includes several arc-shaped plates distributed around the nozzle body, which in turn drive the connecting shaft and the nozzle body to rotate to adjust the angle.

[0010] Preferably, the polygonal box structure of the mounting base has multiple sides, and the mounting holes are distributed on different sides of the mounting base.

[0011] Preferably, the inner diameter of the mounting hole is adapted to the outer diameter of the connecting shaft to enable the connecting shaft to be installed and rotated within the mounting hole.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art:

[0013] This synthetic leather spraying device features a multi-angle nozzle assembly. The mounting base, shaped like a polygonal box with multiple circular mounting holes distributed at various angles on different sides, provides a foundation for multi-angle installation of multiple nozzle assemblies. Each nozzle assembly contains a nozzle body with an externally threaded cylindrical structure and a serrated edge at the front nozzle. It is mounted via a connecting shaft that matches the inner diameter of the mounting hole. Simultaneously, an adjusting plate of the adjusting component connects to the connecting shaft.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1-4As shown, a multi-angle nozzle assembly 2 of a synthetic leather spraying device includes a polygonal box-shaped mounting base 1 with multiple circular mounting holes 11 distributed on different sides of the mounting base 1 at multiple angles. Multiple nozzle assemblies 2 are correspondingly mounted at each mounting hole 11. Each nozzle assembly 2 has a nozzle body 21, which is a cylindrical structure with external threads and a serrated edge at the front nozzle. The nozzle body 21 is connected to the mounting holes 11 of the mounting base 1 via a connecting shaft 22. One end of the connecting shaft 22 is fixed to the nozzle body 21, and the other end is connected to an adjusting component. The adjusting plate in the adjusting component is flat and connected to the connecting shaft 22. A guide plate structure 23 is located beside the connection between the adjusting plate and the connecting shaft 22, and consists of several arc-shaped plates surrounding the nozzle body 21. This structure can drive the connecting shaft 22 and the nozzle body 21 to rotate and adjust the angle. The inner diameter of the mounting hole 11 is adapted to the outer diameter of the connecting shaft 22, facilitating the installation and rotation of the connecting shaft 22.

[0025] In this implementation scheme, from an operational perspective, the polygonal box structure of the mounting base 1 and the multi-angled mounting holes 11 provide a basic mounting position for the nozzle assembly 2. The mounting holes 11 on different sides allow for initial angle differences in the nozzle installation. The matching dimensions of the connecting shaft 22 and the mounting holes 11 ensure stable rotation adjustment. In terms of innovation, the guide plate structure 23, driven by an arc-shaped plate, combined with the rotation of the connecting shaft 22, enables flexible adjustment of the nozzle angle, and the serrated nozzle ensures more uniform spraying. The structure of the mounting base 1 solves the problem of traditional single installation angle, and the cooperation between the adjusting component and the connecting shaft 22 solves the problem of difficult angle adjustment. The synergistic effect of these structures improves spraying efficiency and quality.

[0026] In practical use, the multi-angle nozzle assembly 2 needs to be connected to the synthetic leather conveyor roller, paint storage tank and pressure pump. The mounting base 1 can be made of 304 stainless steel, the connecting shaft 22 is made of 45 steel and chrome-plated, and the nozzle body 21 is made of polytetrafluoroethylene to avoid paint adhesion. At the same time, it needs to be used with a solenoid valve to realize paint on / off control. The nozzle angle and conveyor roller speed are adjusted in conjunction with the PLC control system to ensure stable and efficient spraying process. The paint needs to be transported from the storage tank to the nozzle of the nozzle body 21 through a hose via the pressure pump. The whole system also needs to be equipped with a filter device to prevent impurities from clogging the nozzle.

[0027] Specifically, during actual installation, the mounting base 1 can be fixed to the frame of the synthetic leather production line using bolt assemblies. The frame has pre-set oblong holes to adjust the position of the mounting base 1 along the synthetic leather conveying direction. Before installation, the level of the mounting base 1 must be calibrated using a level. Before use, the operator must use a hydraulic lifting platform (as in existing technology) to hoist the storage tank to the designated height, connect the high-pressure hose to the interface at the rear end of the nozzle body 21 using a quick-connect coupling, and simultaneously connect the control circuit of the adjusting component to the main control cabinet of the production line. The relay module in the main control cabinet controls the start and stop of the guide plate structure 23. During operation, the initial spraying angle, paint flow rate, and spray pressure parameters of each nozzle assembly 2 are first manually set on the touchscreen. These parameters are transmitted to the PLC control via the industrial bus. The controller drives the drive motor of the guide plate structure 23 to rotate the arc plate, causing the connecting shaft 22 to rotate to a preset angle within the mounting hole 11. When the synthetic leather is conveyed by the conveyor roller to the area below the nozzle assembly 2, the photoelectric sensor sends a signal to the controller. The controller opens the pneumatic valve in the paint delivery pipeline. After being pressurized by the pressurizing pump, the paint is delivered to the nozzle body 21 through the flow channel inside the connecting shaft 22 and finally atomized and sprayed out from the serrated nozzle. If the angle needs to be adjusted during the spraying process, the operator can temporarily trigger the adjustment program through the foot switch to finely adjust the connecting shaft 22 of the corresponding nozzle assembly 2 within the range of ±30°. After the spraying is completed, the pneumatic valve is closed and the cleaning program is started. The nozzle body 21 and the internal flow channel are rinsed with high-pressure water to prevent paint residue from hardening.

[0028] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
