Description

Technical Field

[0001] The present application relates to the technical field of cosmetic filling equipment, and in particular to an easily replaceable filling needle nozzle structure. Background Art

[0002] In the production process of cosmetic products, in order to ensure that the quality and performance of each batch of products remain consistent and reduce product quality fluctuations caused by differences in human operations, automated filling equipment is generally used. The use of automated filling equipment can greatly increase production speed, reduce labor costs, and accurately control the net content of the product in each container to ensure that the product meets the specifications indicated on the label. The filling nozzle is an important component in the automated filling equipment, and its design and performance directly affect the efficiency of cosmetic filling and product quality.

[0003] The filling needle nozzle in the automatic filling equipment in the related art is a welded fixed needle nozzle with fixed specifications and dimensions. It cannot be replaced when it is broken or bent, and the maintenance is complicated and requires welding. In order to solve the problems existing in the related art, an easily replaceable filling needle nozzle structure is specially provided. Utility Model Content

[0004] The present application provides an easily replaceable filling needle nozzle structure, which aims to realize convenient and timely disassembly and installation of the filling needle nozzle when the filling needle nozzle is broken or damaged or needs to be replaced with a needle nozzle of different size and specifications in actual production.

[0005] The present application provides an easily replaceable filling needle nozzle structure adopts the following technical solution:

[0006] A filling needle nozzle structure that is easily replaceable comprises a connector and a capillary needle tube detachably arranged on the connector. A clamp is arranged at one end of the capillary needle tube close to the connector. The diameter of the cross section of the clamp increases from top to bottom and the outer surface is smooth.

[0007] By adopting the above technical solution: this structure makes it possible to conveniently and promptly disassemble and install the filling needle tube in actual production when it is broken or damaged or needs to be replaced with a needle tube of a different size. Since the capillary needle tube is detachably arranged on the connector, when replacement or maintenance is required, the operator only needs to simply remove the damaged capillary needle tube and then install a new capillary needle tube or a capillary needle tube of a different size.

[0008] Preferably, a plurality of oblique grooves are provided on the outer surface of the clamp.

[0009] By adopting the above technical solution: due to the presence of the inclined groove, the clamp can produce a certain deformation when subjected to external force, so as to better adapt to the shape and size changes of the connector. This elastic deformation helps to ensure a close fit between the clamp and the connector, and improves the fastening ability;

[0010] In addition, when external force acts on the clamp, the bevel groove can disperse the pressure to various parts of the clamp instead of concentrating it on a certain point. This effect of dispersing pressure helps to improve the bearing capacity and stability of the clamp, enabling it to better withstand various force changes that may occur during work and maintain the tightening effect on the capillary needle tube.

[0011] Preferably, the inner surface of the clamp is provided with an anti-slip texture.

[0012] By adopting the above technical solution: the anti-slip texture significantly enhances the friction between the clamp and the capillary needle tube. This increased friction can ensure that the clamp can be firmly maintained on the capillary needle tube when subjected to external force or vibration, and will not easily slip or shift.

[0013] Preferably, a limiting ring is further provided at one end of the capillary needle tube close to the connector, and the limiting ring is provided at the bottom of the clamp.

[0014] By adopting the above technical solution: the limiting ring serves as a fixed supporting point, so that it has a certain supporting effect on the clamp and reduces the risk of falling off and loosening.

[0015] Preferably, the connector is provided with a mounting interface for connecting the capillary needle tube, and the inner diameter of the mounting interface is larger than the outer diameter of the capillary needle tube and is equivalent to the maximum diameter of the cross section of the clamp.

[0016] By adopting the above technical solution: the capillary needle tube can be easily inserted into the installation interface to achieve preliminary connection with the connector. Since the inner diameter of the installation interface is larger than the outer diameter of the capillary needle tube, this avoids jamming or damage caused by size mismatch during installation, thereby improving the convenience and efficiency of installation.

[0017] In addition, the inner diameter of the mounting interface is equivalent to the maximum diameter of the cross section of the clamp. This design ensures that the clamp can fit tightly on the mounting interface, thereby effectively fixing the capillary tube. When the clamp is tightened, the maximum diameter of its cross section matches the inner diameter of the mounting interface, so that the clamp can evenly apply pressure between the connector and the capillary tube, preventing the capillary tube from slipping or loosening.

[0018] Preferably, a locking piece for locking and fixing the capillary needle tube is provided on the mounting interface.

[0019] By adopting the above technical solution, it is possible to ensure that the capillary needle is firmly fixed in the installation interface.

[0020] Preferably, the locking member is a clamping cap, and the outer side surface of the mounting interface is provided with an external thread matched with the clamping cap.

[0021] By adopting the above technical solution: rotating the locking cap can easily achieve close cooperation with the external thread of the installation interface, thereby firmly locking the capillary needle tube. This mechanical locking method has the characteristics of simple operation and uniform locking force, ensuring the stability of the capillary needle tube during operation.

[0022] Preferably, the locking member is a snap-fit ​​cap, and the outer side surface of the mounting interface is provided with a snap-fit ​​block matched with the snap-fit ​​cap.

[0023] By adopting the above technical solution, the operator only needs to align the clamping cap with the clamping block, and then apply a certain amount of pressure or rotation to achieve a tight fit between the clamping cap and the clamping block. This operation process, which can be completed without the use of tools, greatly improves the efficiency of installation and disassembly.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. This structure realizes the quick disassembly and installation of the capillary needle tube. The capillary needle tube is detachably arranged on the connector. When replacement or maintenance is required, the operator can simply remove the damaged capillary needle tube and then install a new capillary needle tube or a capillary needle tube of a different size. This design improves production efficiency, reduces maintenance costs, and adapts to the needs of different application scenarios;

[0026] 2. This structure achieves a firm fixation of the capillary needle tube through the coordinated use of the clamp and the locking piece. The oblique groove on the clamp enables it to fit tightly on the installation interface, and the anti-slip texture enhances the friction between the clamp and the capillary needle tube to prevent slippage or loosening. At the same time, the use of locking pieces such as tightening caps or snap-on caps further enhances the fixing effect of the capillary needle tube in the installation interface. This double fixing mechanism ensures the accuracy and stability of filling. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] Example 1

[0033] Example 1 of the present application discloses a filling needle nozzle structure that is easy to replace, referring to Figure 1 and Figure 2 , comprising a connector 1 and a capillary needle tube 2 which are sequentially installed from top to bottom, wherein a hoop 3 is sleeved on one end of the capillary needle tube 2 close to the connector 1, the cross section of the hoop 3 increases sequentially from top to bottom and the outer surface is smooth, and a limiting ring 4 is also installed below the hoop 3 to provide stable support for the hoop 3;

[0034] A mounting interface 11 is provided at the bottom of the connector 1. The inner diameter of the mounting interface 11 is larger than the outer diameter of the capillary tube 2 and is equivalent to the maximum diameter of the cross section of the clamp 3, so that the capillary tube 2 can be easily inserted into the mounting interface 11.

[0035] Furthermore, due to the special design of the clamp 3 , when external pressure is applied, the clamp 3 can undergo a certain elastic deformation and push into the mounting interface 11 to tighten the capillary tube 2 , thereby reducing the slippage or loosening of the capillary tube 2 .

[0036] To strengthen the fixation between the clamp 3 and the connector 1, and between the clamp 3 and the capillary tube 2, refer to Figure 2 , the outer surface of the clamp 3 is provided with inclined grooves 31 at equal intervals, and the inner surface thereof is etched with anti-slip textures 32, so that the clamp 3 can produce a certain deformation when subjected to external force, thereby better adapting to the shape and size changes of the connector 1. This elastic deformation helps to ensure a close fit between the clamp 3 and the connector 1, thereby improving the fastening ability;

[0037] In addition, the anti-slip texture 32 significantly enhances the friction between the clamp 3 and the capillary tube 2. This increased friction ensures that the clamp 3 can be firmly held on the capillary tube 2 when subjected to external force or vibration, and will not easily slip or shift.

[0038] To further strengthen the locking and fixing of the capillary needle tube 2, refer to Figure 2 A locking piece is installed on the mounting interface 11. In Example 1 of the present application, a locking cap 5 is used as the locking piece, and an external thread 6 that is compatible with the internal thread of the locking cap 5 is provided on the outer side of the mounting interface 11. By rotating the locking cap 5, a close fit with the external thread 6 of the mounting interface 11 can be easily achieved, thereby achieving a firm locking of the capillary needle tube 2.

[0039] The working process and implementation principle of Example 1 are as follows:

[0040] The operator inserts the capillary needle tube 2 into the installation interface 11 of the connector 1. Since the inner diameter of the installation interface 11 is designed to be slightly larger than the outer diameter of the capillary needle tube 2, this operation becomes relatively easy. At the same time, the hoop 3 is sleeved on the end of the capillary needle tube 2 close to the connector 1, and a limiting ring 4 is installed at the bottom of the hoop 3 to support the hoop 3. Since the cross section of the hoop 3 increases from top to bottom, it can partially enter the installation interface 11.

[0041] Then, a certain external force is applied to the hoop 3 to make it deform elastically. Due to the design of the inclined groove 31 on the outer surface of the hoop 3, it can deform more easily to adapt to the shape and size of the installation interface 11. As the hoop 3 deforms, its top will be further pushed into the installation interface 11, thereby tightly wrapping the capillary needle tube 2. This tight fit effectively reduces the slippage or looseness of the capillary needle tube 2;

[0042] At the same time, the anti-skid texture 32 on the inner surface of the clamp 3 enhances the friction between the clamp 3 and the capillary tube 2. This increased friction ensures that the clamp 3 can be firmly held on the capillary tube 2 when subjected to external force or vibration, and will not easily slip off or shift.

[0043] In order to further enhance the fixing effect of the capillary needle tube 2, the clamping cap 5 is installed on the mounting interface 11, and the clamping cap 5 is rotated to make it tightly fit with the external thread 6 of the mounting interface 11, thereby achieving a firm locking of the capillary needle tube 2;

[0044] Finally, when the capillary needle tube 2 needs to be replaced, the operator only needs to rotate the locking cap 5 in the opposite direction to release its lock on the mounting interface 11. Then, they can easily remove the clamp 3 and the capillary needle tube 2 and install a new or capillary needle tube 2 of a different size. The whole process does not require the use of special tools and the operation is simple and quick.

[0045] Example 2

[0046] Example 2 of the present application discloses a filling needle nozzle structure that is easy to replace, which is different from Example 1 in that, referring to Figure 3 The locking member used in Example 2 of the present application is a clamping cap 7, and a corresponding clamping block 8 is installed on the outer side of the mounting interface 11.

[0047] The working process and implementation principle of Example 2 are as follows: the operator inserts the capillary needle tube 2 into the installation interface 11 of the connector 1. Since the inner diameter of the installation interface 11 is designed to be slightly larger than the outer diameter of the capillary needle tube 2, this operation becomes relatively easy. At the same time, the hoop 3 is sleeved on one end of the capillary needle tube 2 close to the connector 1, and a limiting ring 4 is installed at the bottom thereof to support the hoop 3. Since the cross section of the hoop 3 increases from top to bottom, it can partially enter the installation interface 11.

[0048] Then, a certain external force is applied to the hoop 3 to make it deform elastically. Due to the design of the inclined groove 31 on the outer surface of the hoop 3, it can deform more easily to adapt to the shape and size of the installation interface 11. As the hoop 3 deforms, its top will be further pushed into the installation interface 11, thereby tightly wrapping the capillary needle tube 2. This tight fit effectively reduces the slippage or looseness of the capillary needle tube 2;

[0049] At the same time, the anti-skid texture 32 on the inner surface of the clamp 3 enhances the friction between the clamp 3 and the capillary tube 2. This increased friction ensures that the clamp 3 can be firmly held on the capillary tube 2 when subjected to external force or vibration, and will not easily slip off or shift.

[0050] In order to further enhance the fixing effect of the capillary needle tube 2, the clamping cap 7 is aligned with the clamping block 8 on the outer side of the mounting interface 11, and a certain pressure is applied and an appropriate rotation is performed to form a tight clamping connection between the clamping cap 7 and the clamping block 8. This clamping connection method does not require the use of threads or other complex mechanical structures, so the operation is simpler and faster;

[0051] When the capillary needle tube 2 needs to be replaced, the operator only needs to apply a certain amount of pressure and perform appropriate rotation in the opposite direction to conveniently remove the old capillary needle tube 2 and install a new capillary needle tube 2 or a capillary needle tube 2 of a different size.

[0052] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
