Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic filling, and specifically relates to a drip-proof filling head structure. Background Art

[0002] In the field of cosmetic production, filling is a key link. With the continuous development of the cosmetic market and the increasing requirements of consumers for product quality, the requirements for cosmetic filling technology are becoming more and more stringent.

[0003] In the existing technology, the filling head is usually installed on the production line, and then liquid is conveyed into the filling head. When the filling is completed, due to the change in liquid pressure in the filling head or the gravity of the residual liquid, the filling head is prone to dripping, which will not only cause waste of cosmetics, but also may pollute the production environment and increase the cleaning cost. Secondly, for products such as low-viscosity lotion and perfume, the quality of the products may also be affected due to dripping problems.

[0004] In view of the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0005] In view of the deficiencies of the above-mentioned existing technology, the purpose of the utility model is to provide a drip-proof filling head structure, aiming to solve the problem that when the filling is completed, due to the change in liquid pressure in the filling head or the gravity of the residual liquid, the filling head is prone to dripping.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A drip-proof filling head structure includes a sleeve installed on a filling machine, a spray head for filling cosmetics, and a closing component for blocking the downward continuous flow of liquid material inside the sleeve. The spray head is fixedly arranged at the bottom of the sleeve, the closing component is located between the sleeve and the spray head, the closing component includes a sleeve plate slidably connected to the inner side wall of the sleeve, a limiting ring is fixedly arranged on the inner side wall of the sleeve plate, a rubber baffle is hinged to the outer side wall of the limiting ring, an upper limiting rod is fixedly connected to the bottom of the rubber baffle, a tension spring is fixedly connected to the bottom of the upper limiting rod, a lower limiting rod is fixedly connected to the inner side wall of the sleeve plate, and the end of the tension spring far away from the upper limiting rod is fixedly connected to the lower limiting rod.

[0008] As a further improvement of the above technical scheme, four rubber baffles are provided, and the four rubber baffles are circumferentially and arrayedly distributed inside the sleeve plate. By arranging four rubber baffles, the inside of the sleeve is blocked.

[0009] As a further improvement of the above technical solution, a clamping block is fixedly connected to the sleeve plate, a clamping groove adapted to the clamping block is formed in the sleeve plate, and the tension spring is arranged between the clamping block and the clamping groove. By providing the clamping block and the clamping groove, the splicing of two adjacent rubber baffles is facilitated.

[0010] As a further improvement of the above technical solution, an annular plate is arranged at the connection between the sleeve and the spray head, and the inner side wall of the annular plate is slidably connected to the outer side wall of the bottom of the limiting ring. By providing the annular plate, the stability of the up-and-down movement of the sleeve plate is increased.

[0011] As a further improvement of the above technical solution, a buffer spring is fixedly connected to the top of the annular plate, and the top end of the buffer spring is fixedly connected to the sleeve plate. By providing the buffer spring, buffer treatment is performed on the sleeve plate, and the service life of the sealing assembly is increased.

[0012] As a further improvement of the above technical solution, a liquid inlet pipe is fixedly communicated with the outer side wall of the sleeve, and a connecting flange is connected to the end of the liquid inlet pipe far away from the sleeve at a certain height. By providing the liquid inlet pipe and the connecting flange, it is convenient to flush liquid materials into the sleeve.

[0013] As a further improvement of the above technical solution, a mounting disc is fixedly connected to the top of the sleeve, a threaded hole is formed in the top of the mounting disc, and the sleeve is detachably mounted at a specific position on the filling machine through the mounting disc and the threaded hole. By providing the mounting disc and the threaded hole, it is convenient to mount the sleeve on different types of filling machines.

[0014] In summary, the technical effects and advantages of the present utility model are as follows: For the anti-drip filling head structure, through the combined use of the limiting ring and the rubber baffle, the inside of the sleeve is sealed. Then, through the combined use of the upper limiting rod, the tension spring and the lower limiting rod, the sleeve is quickly sealed when the filling stops, preventing the liquid from flowing out continuously, thus avoiding the occurrence of dripping phenomenon, and further reducing the waste of materials and the pollution of the working environment.

[0015] Through the action of the annular plate, the stability of the up-and-down movement of the area below the sleeve plate is increased. Then, through the action of the buffer spring, the sleeve plate is further stably buffered, absorbing part of the impact force to protect the sealing assembly.

[0016] Through the combined use of the mounting disc and the threaded hole, the installation of the sleeve is facilitated. Through the combined use of the liquid inlet pipe and the connecting flange, it is convenient to fill the liquid into the sleeve, so as to adapt to different types of filling machines and improve the versatility of the filling head.

[0024] The present utility model provides a drip-proof filling head structure. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further details the present utility model with reference to the attached drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0025] As Figures 1-4As shown in the figure, this embodiment provides a technical solution: an anti-drip filling head structure, which includes a sleeve 1 installed on a filling machine, a spray head 2 for filling cosmetics, and a sealing component 3 for blocking the continuous downward flow of liquid materials inside the sleeve 1. The sealing component 3 is located below the sleeve 1. In the middle and upper area of the sealing component 3, the opening gradually decreases from top to bottom. The spray head 2 is fixedly arranged at the bottom of the sleeve 1. The sealing component 3 is located between the sleeve 1 and the spray head 2. The sealing component 3 includes a sleeve plate 31 slidably connected to the inner side wall of the sleeve 1. The outer circumference of the sleeve plate 31 is equal to the inner circumference of the sleeve 1. A limiting ring 32 is fixedly arranged on the inner side wall of the sleeve plate 31. A rubber baffle 33 is hinged to the outer side wall of the limiting ring 32. The rubber baffle 33 is hinged to the limiting ring 32 together. A upper limiting rod 34 is fixedly connected to the bottom of the rubber baffle 33. The upper limiting rod 34 is located on one side of the bottom of the rubber baffle 33. A tension spring 35 is fixedly connected to the bottom of the upper limiting rod 34. A lower limiting rod 36 is fixedly connected to the inner side wall of the sleeve plate 31. The tension spring 35 is located between the upper limiting rod 34 and the lower limiting rod 36. One end of the tension spring 35 away from the upper limiting rod 34 is fixedly connected to the lower limiting rod 36. After the liquid flows into the inside of the sleeve 1, the pressure of the liquid acts on the rubber baffle 33. At this time, the rubber baffle 33 overcomes the tension of the tension spring 35 and opens. The liquid flows through the sleeve 1 into the inside of the spray head 2 and is filled into the cosmetics. When the liquid pressure disappears, the tension spring 35 resets the upper limiting rod 34 and the lower limiting rod 36, so that the rubber baffle 33 seals the sleeve 1, avoiding the dripping of the liquid materials after filling.

[0026] As Figure 1 , Figure 2 and Figure 4 shown, there are four rubber baffles 33. The rubber baffles 33 are mainly made of rubber material and have a certain elasticity. The four rubber baffles 33 are distributed in a circular array inside the sleeve plate 31. The four rubber baffles 33 surround together to form a circular shape, and the four rubber baffles 33 block the inside of the sleeve 1.

[0027] As Figure 2 and Figure 4 shown, a block 37 is fixedly connected to the sleeve plate 31. A slot 38 adapted to the block 37 is opened on the sleeve plate 31. The block 37 and the slot 38 are adapted to each other. The tension spring 35 is arranged between the block 37 and the slot 38. The block 37 and the slot 38 on each rubber baffle 33 are symmetrically distributed with the central axis of the rubber baffle 33 as the center. The block 37 and the slot 38 facilitate the splicing between adjacent two rubber baffles 33.

[0028] As Figures 2-3As shown in the figure, an annular plate 4 is provided at the connection between the sleeve 1 and the spray head 2. The annular plate 4 is matched with the connection between the spray head 2 and the annular plate 4. The annular plate 4 is fixed between the sleeve 1 and the spray head 2. The annular plate 4 is coaxial with the sleeve 1. The outer circumference of the annular plate 4 is equal to the inner circumference of the sleeve 1. The inner side wall of the annular plate 4 is slidably connected to the outer side wall of the bottom of the limiting ring 32. The annular plate 4 ensures the stability of the closing assembly 3.

[0029] As Figures 2-3 shown in the figure, a buffer spring 39 is fixedly connected to the top of the annular plate 4. The top end of the buffer spring 39 is fixedly connected to the sleeve plate 31. There are four buffer springs 39, and the four buffer springs 39 are distributed in a circumferential array on the annular plate 4. When the rubber baffle 33 is subjected to a large impact force, the buffer spring 39 further buffers the sleeve plate 31, thereby further protecting the closing assembly 3.

[0030] As Figure 1 shown in the figure, a liquid inlet pipe 5 is fixedly communicated with the outer side wall of the sleeve 1. The end of the liquid inlet pipe 5 away from the sleeve 1 is connected with a connecting flange 6 at a certain height. The pipeline at the outlet of the feeding pump is connected to the liquid inlet pipe 5 through the connecting flange 6. After the feeding pump operates, the liquid material flows into the inside of the sleeve 1 through the liquid inlet pipe 5, so that liquid pressure is generated inside the sleeve 1.

[0031] As Figure 1 shown in the figure, a mounting plate 7 is fixedly connected to the top of the sleeve 1. The mounting plate 7 is coaxial with the sleeve 1. Six threaded holes 8 are provided on the top of the mounting plate 7, and the six threaded holes 8 are distributed in a circumferential array on the mounting plate 7. The sleeve 1 is detachably installed at a specific position on the filling machine through the mounting plate 7 and the threaded holes 8. The sleeve 1 is installed at a specific position on the filling machine through bolts and the corresponding threaded holes 8.

[0032] Working principle: When the filling machine performs the filling operation, the connecting flange 6 is connected to the discharging end of the feeding pump, and the liquid material flows into the sleeve 1 from the liquid inlet pipe 5. Under normal filling conditions, the pressure of the liquid acts on the rubber baffle 33 of the closing assembly 3, causing the rubber baffle 33 to overcome the pulling force of the tension spring 35 and open, so that the liquid can flow out from the sleeve 1 through the spray head 2 and be filled. When the filling stops, the liquid pressure disappears, the tension spring 35 contracts, and then it is reset through the upper limiting rod 34 and the lower limiting rod 36. The rubber baffle 33 closes the sleeve 1 under the restriction of the limiting ring 32, preventing the liquid from flowing downward continuously. At the same time, the clamping block 37 and the clamping groove 38 facilitate the splicing of two adjacent rubber baffles 33. When the rubber baffle 33 is subjected to a large impact force, the buffer spring 39 can absorb part of the impact force, thereby protecting the rubber baffle 33. The annular plate 4 plays a role in stabilizing and assisting in sealing at the connection between the sleeve 1 and the spray head 2, thereby avoiding the leakage of the liquid material after filling.
