Description

Technical Field

[0001] This utility model belongs to the field of spray bar technology, specifically relating to an angle-adjustable spray bar. Background Technology

[0002] The spray bar is the liquid flow carrier, and it constrains the position and direction of the liquid flow through its own liquid outlet.

[0003] In the production of some products, such as large-size packaged products, it is necessary to clean their surfaces. In order to improve the cleaning effect, it is sometimes necessary to spray and rinse from different angles.

[0004] However, current spray booms cannot flexibly and accurately adjust the orientation of the nozzles, resulting in failure to meet actual cleaning requirements. The main issue is that the orientation of the nozzles cannot be seen during installation. Once the spray boom is fixed, the orientation of the nozzles often deviates from the expected angle. Installers need to repeatedly rotate and adjust the spray boom to achieve the desired installation angle. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an angle-adjustable spray bar.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] An angle-adjustable spray bar, the surface of which is provided with an indicator plate, the indicator plate being provided with a same-direction indicator hole and / or a reverse-direction indicator hole for distinguishing the direction of the spray nozzle;

[0008] The circumferential angle between the indicating direction of the same-direction indicator hole and the direction of the nozzle is 0°, and the circumferential angle between the indicating direction of the opposite-direction indicator hole and the direction of the nozzle is 180°.

[0009] The indicator plate has an arc-shaped hole.

[0010] In this invention, the direction of the spray nozzle is indicated by the same-direction indicator hole or the opposite-direction indicator hole to help the installer determine the circumferential posture of the spray bar, helping the worker to install it in place in one go, avoiding multiple rounds of adjustments and increasing the workload;

[0011] Specifically, the circumferential angle between the direction indicated by the same-direction indicator and the direction of the nozzle is 0°, which means that the direction indicated by the same-direction indicator is the direction of the nozzle. The operator only needs to adjust the spray bar so that the same-direction indicator points to the required angle to determine the direction of the nozzle. The circumferential angle between the direction indicated by the opposite indicator and the direction of the nozzle is 180°, which means that the direction opposite to the direction indicated by the opposite indicator is the direction of the nozzle. The operator can also indirectly confirm the direction of the nozzle by observing the direction indicated by the opposite indicator.

[0012] In situations where orientation is critical, installation tools with circumferential markings can be used. For example, circumferential markings can be pre-drawn on the mounting surface. When the same-direction or opposite-direction indicator holes point to the circumferential markings, the accurate circumferential angle of the nozzle can be confirmed by reading the marking value. It should be noted that the design scheme where the direction of the opposite-direction indicator hole is 180° away from the circumferential angle of the nozzle orientation can adapt to a special situation where there may not be enough space to draw circumferential markings on the mounting surface, especially on the side where the nozzle orientation is located, but the accuracy of the installation angle still needs to be ensured. In this case, by setting the direction of the opposite-direction indicator hole to be 180° away from the circumferential angle of the nozzle orientation, the circumferential markings can be arranged on the side with sufficient drawing area, thereby achieving precise installation.

[0013] During installation, since it is necessary to adjust the circumferential angle of the spray bar and to ensure that the bolts can be locked into the screw holes in a defined position, a curved waist-shaped hole is specially designed. After the bolt passes through the curved waist-shaped hole, it is locked into the screw hole on the assembly surface, thus completing the fixation of the spray bar. The curved waist-shaped hole is used to expand the fitting range, allowing the spray bar to adjust its circumferential angle within a certain range before locking and fixing.

[0014] In some optional examples, the shape of the same-direction indicator hole or the reverse indicator hole is triangular because the triangle has sharp corners, which can better indicate the scale. However, in practice, other shapes with the ability to indicate the scale can also be used. For example, the same-direction indicator hole is triangular, while the reverse indicator hole is square. This also makes it easier for staff to distinguish between the same-direction indicator hole and the reverse indicator hole.

[0015] As a preferred technical solution of this utility model, the outer surface of the side of the spray bar that is inlet to the liquid is provided with threads, the indicator plate is provided with a mark for indicating the direction of thread tightness, and the end of the spray bar away from the liquid inlet is provided with a screw head.

[0016] This utility model solves the problem of fixing the liquid inlet side of the spray bar. It uses the thread on the outer surface of the spray bar to connect with the assembly surface. When locking by the threaded connection, the same-direction indicator hole or the opposite-direction indicator hole will also rotate continuously during the locking process. The direction of the same-direction indicator hole or the opposite-direction indicator hole and the degree of locking are used to determine whether the rotation should be stopped.

[0017] The markings indicate the direction of thread tightening, making it easy for subsequent maintenance personnel to know how to tighten or loosen the spray bar;

[0018] The screw head makes it easier for workers to apply force to screw the spray bar.

[0019] As a preferred technical solution of this utility model, the circumference of the spray bar is provided with a plurality of baffles for constraining the sealing ring, and the baffles form a space for placing the sealing ring.

[0020] In this invention, since the thread exists on the side of the spray bar where the liquid enters, a sealing ring needs to be installed on this side to prevent leakage. The flange is used to constrain the sealing ring and prevent it from shifting.

[0021] The beneficial effects of this utility model are:

[0022] 1. The spray nozzle orientation is indicated by the same-direction or opposite-direction indicator holes to help installers determine the circumferential posture of the spray bar, enabling workers to install it in place in one go and avoid multiple adjustments, thus reducing workload; 2. The structure is simple, easy to install, and provides excellent spray cleaning effect. Attached Figure Description

[0038] Example

[0039] like Figures 1-8 As shown, this embodiment provides an angle-adjustable spray bar, which is used in the cleaning process of large-size packaged products. The large-size packaged products consist of a carrier board ZB and a chip XP. The large-size packaged products are horizontally transported by a conveyor to the spray cleaning area composed of spray bars to complete non-stop through cleaning. The spray pipes are installed in two rows, one above the other, and pressurized liquid is used to clean the products from the top and the bottom of the large-size packaged products at the same time.

[0040] The surface of the spray bar is provided with an indicator plate 3. The indicator plate 3 is provided with a unidirectional indicator hole 33 and a reverse indicator hole 34 for distinguishing the orientation of the spray hole 1. The unidirectional indicator hole 33 and the reverse indicator hole 34 are both triangular in shape.

[0041] The circumferential angle between the indicating direction of the same-direction indicator hole 33 and the direction of the nozzle 1 is 0°, and the circumferential angle between the indicating direction of the opposite-direction indicator hole 34 and the direction of the nozzle 1 is 180°.

[0042] The indicator plate 3 is provided with an arc-shaped waist-shaped hole 31;

[0043] The outer surface of the spray bar on the side where the liquid enters is provided with a thread 2, and the indicator plate 3 is provided with a mark for indicating the tightness and direction of the thread 2. The circumference of the spray bar is provided with several flanges 4 for constraining the sealing ring, and the flanges 4 form a space for placing the sealing ring. The end of the spray bar away from the liquid inlet is provided with a screw head 32.

[0044] In this embodiment, during installation, the thread on the liquid inlet side of the spray bar is first connected to the pipe supplying the cleaning fluid via a threaded connection. The operator determines the orientation of the spray hole 1 by observing the value of the circumferential scale aligned with the pointed tip of the same direction indicator hole 33. When the same direction indicator hole 33 points to the required angle and the turning resistance is large, the operator can stop turning the screw head 32. At this time, the liquid inlet end of the spray bar is fixed by a threaded connection and sealed by the sealing ring between the flanges 4.

[0045] Subsequently, the staff passed the bolt through the waist-shaped hole 31 and locked it into the screw hole on the assembly surface. By pressing the indicator plate 3 with the bolt, the spray bar can be fixed at one end of the indicator plate 3.

[0046] Because the waist-shaped hole 31 is designed with an arc, when it is necessary to rotate the spray bar at a certain angle to adjust the orientation of the spray hole 1, the waist-shaped hole 31 can still allow the bolt to pass through and complete the clamping and fixing of the indicator plate 3.

[0047] After installation, the pressurized liquid flows into the inner cavity of the spray bar through the inlet and is then sprayed through the nozzle 1. The spray angle is determined by the orientation of the nozzle 1.

[0048] In this embodiment, to easily distinguish between the same-direction indicator hole 33 and the opposite-direction indicator hole 34, two sets of markings indicating the tightening / untightening direction are provided. Figure 6 In the middle, the tension mark near the same direction indicator hole 33 has the word "loose" in a mirror font, while the tension mark near the opposite direction indicator hole 34 has the word "loose" set to a normal font. Through some simple marking methods, the same direction indicator hole 33 and the opposite direction indicator hole 34 can be easily and conveniently distinguished.

[0049] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
