Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a spraying structure of BIPV panel glass. Background Art

[0002] The current coating method for solvent-based inks in the market is mainly screen printing, which has low production efficiency and high ink loss. As the product size increases, uneven thickness is very likely to occur.

[0003] Compared with the silk screen printing process, the electrostatic rotary cup spraying process has a more uniform coating, less ink loss and higher efficiency.

[0004] Electrostatic rotary cup spraying requires a corresponding spraying structure. The cup mouth of the rotary cup is relatively sharp. Therefore, when installing the rotary cup on the rotor, the rotary cup and the rotor need to be installed tightly, which requires a strong force. Therefore, the operator is likely to touch the cup mouth when applying force, which can easily cause injury to the operator. Utility Model Content

[0005] The purpose of this utility model is to provide a spraying structure for BIPV panel glass, which combines the bell and the cover body. During installation, the bell and the rotor can be tightly installed by the force applied to the cover body, thereby simplifying the installation structure and preventing the operator from being scratched by the bell mouth.

[0006] In order to achieve the above objectives, the technical solution adopted by the present invention is:

[0007] A spraying structure for BIPV panel glass includes a main body sleeve, which is provided with a rotor and an impeller that cooperate with each other. The rotor is equipped with a rotary cup, and a cover is provided on the outside of the rotary cup. The rotating part of the rotary cup is fixedly sleeved with a rotating block. The cover is provided with a slot that cooperates with the rotating block. The rotating block is inserted into the slot and can rotate in the slot. The cover can be detachably installed on the main body sleeve.

[0008] Preferably, a bearing that is sleeved and fitted with the rotating block is provided in the slot, and the cover body is composed of two detachable half-cover bodies.

[0009] Preferably, the outer side of the cover body is provided with mounting notches along a circular array, and the cover body and the main body sleeve are locked in the mounting notches by mounting bolts.

[0010] Preferably, a main body air duct is opened in the side wall of the main body sleeve, and a cover body air duct connected to the main body air duct is opened in the cover body, and the main body air duct and the cover body air duct correspond to each other one by one. The cover body air duct is distributed in a ring shape with the rotary cup as the center, and its position corresponds to the inkjet part of the rotary cup.

[0011] Preferably, the main air duct includes part of the side wall of the main sleeve and part of the rear wall of the main sleeve. The main air duct of the rear wall part passes through the outer wall of the main sleeve and is equipped with a blocking block. The blocking block is threadedly matched with the corresponding main air duct part, and an inner hexagon is provided on the outside of the blocking block.

[0012] Preferably, the front wall of the main body sleeve is provided with a mounting hole tangent to the outer wall of the bell, the front end of the rotor is a gear shaft, the end of the bell that cooperates with the rotor is a gear sleeve that cooperates with the gear shaft, and both the rotor and the bell are hollow structures, and this hollow structure constitutes an ink channel.

[0013] The technical effects of the utility model are:

[0016] 3. The design of the main air duct and the cover air duct can assist the rotary cup inkjet, so that the atomized ink can be sprayed into the rotary cup body in time to avoid ink residue and also prevent the atomized ink from spilling.

[0017] 4. The rear wall of the main airway is partially through-designed for easy processing and can be sealed with a blocking block to prevent gas leakage.

[0018] 5. The hollow design of the rotor and the bell forms an ink channel, which allows the ink to enter the bell better and has a certain centrifugal force in the process of entering the bell. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1-2 As shown, the spraying structure of the BIPV panel glass of the present invention includes a main body sleeve 1, which is provided with a rotor 2 and an impeller 3 that cooperate with each other, the rotor 2 is equipped with a rotary cup 4, and a cover body 5 is provided on the outside of the rotary cup 4. The rotating part of the rotary cup 4 is fixedly sleeved with a rotary block 9, and a slot that cooperates with the rotary block 9 is provided in the cover body 5. The rotary block 9 is inserted into the slot and can rotate in the slot. The cover body 5 can be detachably installed on the main body sleeve 1, and an installation notch 11 is provided on the outside of the cover body 5 along the annular array. The cover body 5 and the main body sleeve 1 are locked by installing bolts 12 in the installation notch 11, and a bearing 10 that is sleeved with the rotary block 9 is provided in the slot, and the cover body 5 is composed of two detachable half-cover bodies.

[0028] During the specific installation, the rotating block 9 is first sleeved with the bearing 10, and then the two half-covers are combined into a cover. During the synthesis process, the bearing 10 and the rotating block 9 are inserted into the slot, so that the bell cup 4 and the cover 5 become a whole, and the bell cup 4 can rotate relative to the cover 5. After that, it is only necessary to install the cover 5 and the main sleeve 1 to simultaneously realize the installation of the bell cup 4 and the rotor 2. Specifically, the cover 5 is locked on the main sleeve 1 by the bolt 12 in the installation notch 11. Such installation can ensure that the bell cup 4 and the rotor 1 do not move in the axial direction.

[0029] After the installation is completed, the spraying structure is connected to the entire spraying equipment. The impeller 3 will drive the rotor 2 to rotate under the action of the driving structure (pneumatic motor) of the spraying equipment, and then drive the rotary cup 4 to rotate. At the same time, the ink will also be sent into the rotary cup 4 under the action of the pipeline. The ink in the rotary cup 4 will generate a large centrifugal force under the high-speed rotation of the rotary cup, and the ink will be thrown out along the conical cup wall of the rotary cup through the centrifugal force to realize the inkjet operation.

[0030] It should be noted that when using the spraying structure of the present application to spray the BIPV panel, an electrostatic field will be constructed first. The ink sprayed through the spraying structure will be atomized under the action of the electrostatic field, thereby completing the electrostatic rotary cup spraying operation.

[0031] Example 2

[0032] like Figure 1-2 As shown, the front wall of the main body sleeve 1 of this embodiment is provided with a mounting hole tangent to the outer wall of the bell. The front end of the rotor 2 is a gear shaft, and the end of the bell 4 that cooperates with the rotor is a gear sleeve that cooperates with the gear shaft. The rotor 2 and the bell 4 are both hollow structures, and this hollow structure constitutes the ink channel 6.

[0033] Compared with Example 1, this embodiment introduces in detail the connection structure between the bell 4 and the rotor 2. The two are matched through the gear sleeve and the gear shaft, so that they can ensure that they can rotate synchronously. Combined with the axial limitation of the bell 4 by the cover body 5, the stable rotation of the bell 4 can be ensured. The ink channel 6 is set to a hollow structure of the rotor and the bell, so that the ink in the hollow structure will generate centrifugal force as the rotor rotates.

[0034] Example 3

[0035] like Figure 1-2 As shown, a main body air duct 7 is opened in the side wall of the main body sleeve 1 of this embodiment, and a cover body air duct 8 connected to the main body air duct 7 is opened in the cover body 5, and the main body air duct 7 and the cover body air duct 7 correspond one to one, and the cover body air duct 8 is distributed in a ring shape with the rotary cup 4 as the center, and its position corresponds to the inkjet part of the rotary cup 4.

[0036] Compared with Example 1, this embodiment adds a main air duct 7 and a cover air duct 8 on its basis. While performing rotary cup spraying, an air flow can be formed through the main air duct and the cover air duct, so that the sprayed atomized ink can be blown to accelerate it to act on the BIPV board.

[0037] Example 4

[0038] Compared with Example 3, the main air duct 7 includes a part of the side wall of the main sleeve 1 and a part of the rear wall of the main sleeve 1. The main air duct 7 of the rear wall part passes through the outer wall of the main sleeve 1 and is equipped with a blocking block 13. The blocking block 13 is threadedly matched with the corresponding part of the main air duct 7, and an inner hexagon is provided on the outside of the blocking block 13.

[0039] It should be noted that the design of the main air duct 7 of the rear wall part of this embodiment penetrating the outer wall of the main sleeve 1 is for the convenience of processing, and the hexagonal blocking block 13 is used for blocking, which facilitates the removal and installation of the blocking block 13 and facilitates the cleaning of the air duct.

[0040] It should be further clarified that, in the description of the present invention, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0041] Unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or removable connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0042] Unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
