Description

Technical Field

[0001] The utility model relates to the technical field of vacuum equipment, in particular to a novel vacuum nozzle. Background Art

[0002] In modern industrial production and scientific research, vacuum nozzles are increasingly widely used. Vacuum nozzles are widely used in fields such as machinery, electronics, packaging, printing, plastics, and robots in industrial automation.

[0003] In the existing vacuum nozzle technology, there is usually only one fixed discharge channel. This leads to many limitations and deficiencies in practical applications: Lack of flexibility: Since there is only one discharge channel, it is impossible to flexibly adjust the discharge speed, flow rate, and spraying range according to different working scenarios and requirements. For example, in some process links that require fine spraying, a single discharge channel cannot provide a small flow rate and precise spraying control, making it difficult to ensure the accuracy and quality of work; while in operations that require large-area and rapid spraying, it is impossible to quickly increase the flow rate and spraying range, seriously affecting work efficiency. Poor adaptability: Facing diverse materials and working conditions, a single discharge channel is difficult to adapt to. Different materials may require different flow rates and spraying methods, and the existing single channel cannot meet these different requirements, restricting the versatility of vacuum nozzles in various application scenarios. Single function: Having only one discharge channel makes the function of the vacuum nozzle relatively single, unable to meet the requirements for different spraying effects in some complex processes, restricting its application and development in a wider range of fields. In order to improve it, a novel vacuum nozzle is proposed here. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a novel vacuum nozzle is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel vacuum nozzle, comprising a connecting pipe and a material spraying pipe. A fixing ring is provided on the connecting pipe. Three conversion channels and a common channel are provided in the material spraying pipe. The inner diameters of the three conversion channels are different. The three conversion channels are all communicated with the common channel through discharge channels. A fixing plate is installed on the material spraying pipe. A cavity is provided inside the fixing plate. A sliding rod is provided in the cavity. A movable plate is slidably sleeved on the sliding rod through an elastic mechanism. The movable plate is connected to the fixing ring through a positioning mechanism.

[0007] Preferably, the elastic mechanism includes a spring sleeved outside the sliding rod. The two ends of the spring are elastically connected to the inner wall of the cavity and the outer wall of the movable plate respectively.

[0008] Preferably, the positioning mechanism includes a positioning block installed on the movable plate and sliding through the inner wall of the cavity. The bottom of the fixed ring is provided with an annular connection groove corresponding to the fixed plate, and the outer wall of the fixed ring is provided with a positioning hole communicating with the annular connection groove and corresponding to the positioning block.

[0009] Preferably, a pressing block is also installed on the movable plate, and the pressing block also slides through the inner wall of the cavity and extends outside the fixed plate.

[0010] Preferably, the upper end surface of the material spraying pipe is provided with an annular rotating groove corresponding to the connecting pipe, and a sealing ring is installed on the connecting pipe and located in the annular rotating groove.

[0011] Preferably, the top view of the fixed plate is designed in an arc shape, and the surfaces of the fixed plate in contact with the annular connection groove are polished.

[0012] Advantages of the utility model:

[0013] 1. It has three switchable conversion channels, which can flexibly select the appropriate channel according to different working requirements to achieve precise control of the spraying speed, flow rate and range. Whether it is a high-precision operation that requires fine spraying or a task of large-area rapid spraying, it can be quickly adjusted to the best state, thus greatly improving the work efficiency and quality.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Referring to Figures 1-3 , the new vacuum nozzle of the present utility model mainly consists of important components such as a connecting pipe 1, a fixing ring 2, a material spraying pipe 3, etc. The connecting pipe 1 serves as the inlet for material transmission and undertakes the key task of introducing the externally supplied material into the nozzle. The fixing ring 2 provided on it provides a basis for subsequent connection and fixing operations.

[0021] The material spraying pipe 3 is the core part of the entire nozzle, and three conversion channels 9 and a common channel 11 are designed inside. These three conversion channels 9 have different specifications and characteristics and can be flexibly switched according to the diverse requirements of the actual working scenarios. They are all connected to the common channel 11 through the discharge channels 10, thus realizing the efficient and precise conveyance of materials. For example, in some process links with extremely high requirements for spraying accuracy, the conversion channel 9 with a smaller inner diameter and stable flow rate can be enabled to ensure the precise distribution of materials; while in the operation that requires large-area and rapid spraying, the conversion channel 9 with a larger inner diameter and sufficient flow rate can be switched to, thereby greatly improving the working efficiency.

[0022] A fixing plate 4 is also installed on the material spraying pipe 3, and a cavity 13 is provided inside it. The sliding rod 14 in the cavity 13 provides guidance and support for the movement of the movable plate 15. The movable plate 15 is slidably sleeved on the sliding rod 14 through an elastic mechanism, and the elastic mechanism is mainly composed of a spring 16 sleeved outside the sliding rod 14. The two ends of the spring 16 are elastically connected to the inner wall of the cavity 13 and the outer wall of the movable plate 15 respectively. This design enables the movable plate 15 to move along the sliding rod 14 when subjected to an external force and quickly reset under the elastic restoring force of the spring 16 to maintain a stable working state.

[0023] The movable plate 15 is connected to the fixing ring 2 through a unique positioning mechanism. The positioning mechanism includes a positioning block 17 installed on the movable plate 15 and slidably penetrating the inner wall of the cavity 13. An annular connection groove 12 corresponding to the fixing plate 4 is provided at the bottom of the fixing ring 2, and a positioning hole 6 corresponding to the annular connection groove 12 and the positioning block 17 is provided on the outer wall of the fixing ring 2. When the positioning block 17 accurately inserts into the positioning hole 6, it can ensure the firm and reliable connection between the connecting pipe 1 and the material spraying pipe 3, and at this time, one of the conversion channels 9 is communicated with the connecting pipe 1. This connection method is convenient for quick disassembly and installation when needed.

[0024] In order to further improve the convenience and humanization of operation, a pressing block 5 is also installed on the movable plate 15. The pressing block 5 also slides through the inner wall of the cavity 13 and extends outside the fixing plate 4. The operator only needs to gently press the pressing block 5 to easily release the locking of the positioning block 17 and the positioning hole 6.

[0025] In terms of structural design, an annular rotating groove 7 corresponding to the connecting pipe 1 is provided on the upper end surface of the spraying pipe 3, and a sealing ring 8 installed in the annular rotating groove 7 is provided on the connecting pipe 1. This design makes it so that when the connecting pipe 1 communicates with one of the conversion channels 9, the other two conversion channels 9 are in an occluded state.

[0026] The surfaces of the fixing plate 4 that come into contact with the annular connection groove 12 have all been finely polished, greatly reducing the friction coefficient between the contact surfaces and ensuring smoothness during relative movement.

[0027] When this utility model is in use, according to the requirements of the actual working scenario, if high-precision spraying is required, such as in the fine coating operation of electronic components, a conversion channel 9 with a smaller inner diameter and stable flow rate is selected. During operation, by pressing the pressing block 5, the locking of the positioning block 17 and the positioning hole 6 is released, the connecting pipe 1 is rotated to align the corresponding conversion channel 9 with the connecting pipe 1, and the pressing block 5 is released to re-lock, and the material can be precisely sprayed through this conversion channel 9. And when large-area and rapid spraying is required, such as when painting a large metal surface, the pressing block 5 is also operated for channel switching, and a conversion channel 9 with a larger inner diameter and sufficient flow is selected. After the material passes through the selected conversion channel 9, it enters the common channel 11 through the discharge channel 10 and is ejected.

[0028] The above is only a preferred specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by this utility model, according to the technical solution of this utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of this utility model.
