The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0030] Please refer to Figures 1-6 The present application discloses a cleaning agent filling device, which comprises a rack 1 and a lifting mechanism 2 arranged on the top of the rack 1, and at least one filling mechanism 3 is arranged on the lifting mechanism 2; the filling mechanism 3 comprises a filling pipe 31 arranged on the lifting mechanism 2 and capable of lifting along with the lifting of the lifting mechanism 2, a head cover 32 arranged at the bottom end of the filling pipe 31 and capable of reducing liquid foaming and adsorbing excess liquid, a mixing assembly 33 arranged at the top end of the filling pipe 31 and capable of mixing raw materials during filling, a positioning assembly 34 arranged on the filling pipe 31 and capable of positioning the bottle opening of a container, a linkage assembly 35 arranged on the filling pipe 31 and capable of driving the positioning assembly 34 to lift synchronously, and an extrusion assembly 36 arranged at the top of the positioning assembly 34 and capable of extruding the head cover 32 to discharge the liquid inside the head cover 32 periodically.

[0031] The device further comprises a belt conveyor 4 for conveying the container, a guide frame 5 for guiding the container to move along a fixed line, and a limiting mechanism 6 for preventing the container from moving during filling.

[0032] The present application transports the container to below the filling pipe 31 by the belt conveyor 4, stops the container from moving by the limiting mechanism 6, then drives the filling pipe 31 to move downward by the lifting mechanism 2, makes the positioning assembly 34 move downward first to complete the positioning of the container bottle mouth, then the filling pipe 31 is inserted into the container, and the raw materials in the feeding bin are quantitatively fed into the mixing assembly 33 by the pump, so that the raw materials are uniformly mixed while being filled and conveyed, thereby saving the cost of purchasing mixing equipment, controlling the consistency of the discharged raw materials during each filling, controlling the quality consistency of the finished cleaning agent, and when the product needs to be switched, the filling mechanism 3 is only needed to be washed clean by water, and then the production of another product can be carried out, the mixed finished product enters the container through the head cover 32, after the filling is completed, the lifting mechanism 2 drives the filling pipe 31 to rise, the extrusion assembly 36 extrudes the liquid in the head cover 32 into the container below, and then the container moves to the next process, and in this process, the head cover 32 can absorb the liquid dripping from the filling pipe 31, avoid polluting the container and the belt conveyor 4, and the absorbed liquid will be extruded into the subsequent container in the subsequent filling process, reducing the error of the content of each bottle of finished product.

[0033] In specific implementation, in order to improve the filling efficiency, a plurality of filling mechanisms 3 can be arranged, since a plurality of containers are closely attached to each other during conveying, in order to be able to fill a plurality of containers at the same time and avoid interference between the plurality of filling mechanisms 3, the length of the filling mechanism 3 in the conveying direction is not greater than the length of the container in the conveying direction.

[0034] In an embodiment, the bottom end outlet of the filling pipe 31 is covered by the head cover 32, the bottom end outlet of the filling pipe 31 is located on the side wall of the filling pipe 31, and the first cone 7 is arranged in the filling pipe 31 and used for guiding the liquid to flow out of the plurality of bottom end outlets of the filling pipe 31.

[0035] In this way, the cleaning agent is filled into the container through the side of the filling pipe 31, the contact area between the cleaning agent and the head cover 32 is increased, and the first cone 7 is arranged to make the liquid flow downward along the filling pipe 31 and uniformly flow out of the plurality of outlets under the guidance of the first cone 7.

[0036] In an embodiment, the head cover 32 comprises a support 321 threadedly connected with the filling pipe 31 and a sponge sleeve 322 fixedly arranged on the support 321, the inner diameter of the sponge sleeve 322 in a natural state is not greater than the outer diameter of the filling pipe 31, and the first perforation 323 corresponding to the bottom end outlet of the filling pipe 31 is arranged on the sponge sleeve 322. In this way, the head cover 32 can be regularly disassembled and replaced by the staff, the sponge sleeve 322 on the head cover 32 is prevented from being oxidized and deteriorated to affect the adsorption capacity of the liquid, and the sponge sleeve 322 can be supported by the support 321 to prevent the leakage caused by the deformation of the sponge sleeve 322 due to the impact of the liquid during work.

[0037] In an embodiment, the mixing assembly 33 comprises a barrel 331 arranged at the top end of the filling pipe 31, the barrel 331 is provided with a water inlet pipe 332 for water input, a gas inlet pipe 336 for gas input and a plurality of material inlet pipes 333 for material input at the top end respectively, the output ends of the water inlet pipe 332 and the material inlet pipes 333 are inserted into the barrel 331, the input ends of the water inlet pipe 332 and the material inlet pipes 333 are connected with the material bin through a pump, at least one mixing hopper 334 for collision mixing of the materials is arranged in the barrel 331, the mixing hopper 334 comprises a converging section for collecting liquid, a lifting section for lifting and collision mixing of the liquid and a discharge section for discharging the mixed liquid from the outside to the inside, the converging section is in the shape of a funnel with the inner diameter gradually decreasing from top to bottom, the lifting section is in the shape of a circular truncated cone with the outer diameter gradually increasing from top to bottom, the smallest inner diameter of the converging section coincides with the largest outer diameter of the lifting section, the converging section of the mixing hopper 334 is provided with a second cone 335 for guiding the liquid to be dispersed to all parts of the converging section, the contact angle between the second cone 335 and the converging section is less than 360 degrees;

[0038] The discharge section of the bottom mixing hopper 334 is connected with the top end of the filling pipe 31.

[0039] In this way, after the materials are input into the barrel 331 through the water inlet pipe 332 and the material inlet pipes 333, the materials are first dispersed to all parts of the converging section along the second cone 335, then flow along the converging section, collide with the liquid in other parts after flowing into the lifting section, and are further mixed, and then the mixed liquid is discharged along the discharge section, so as to achieve the purpose of mixing the materials during the filling process, and at the same time, during the discharge of the liquid, the barrel 331 is filled with gas through the gas inlet pipe 336, so that the gas pressure in the barrel 331 is increased, and the liquid is discharged faster.

[0040] It should be noted that although the cleaning agent for medical devices requires no foam or little foam, the cleaning agent filled into the container will still generate foam due to the gas filled into the barrel 331 through the gas inlet pipe 336, therefore, the gas inlet pipe 336 cannot be arranged alone and needs to be used together with the sponge sleeve 322, before filling, the sponge sleeve 322 needs to be used to block the mouth of the filling container, since the sponge has a certain air permeability, the gas and foam in the container are discharged out of the container through the sponge during filling, and the foam is quickly defoamed when passing through the sponge and will not overflow out of the container.

[0041] Preferably, the water inlet pipe 332 is located between the plurality of material inlet pipes 333, and the outlet directions of the material inlet pipes 333 are all towards the water inlet pipe 332, so that the output materials can collide and mix with the water.

[0042] In an embodiment, a plurality of guide plates 8 for guiding the rotational mixing of the liquid are arranged in the discharge section of the mixing hopper 334. The guide plates 8 are spiral vanes arranged in the discharge section of the mixing hopper 334. In this way, the liquid flowing along the wall of the discharge section is guided to rotate and fall by the guide plates 8, collides with the liquid falling directly from the middle of the discharge section, and further improves the mixing effect.

[0043] In an embodiment, a plurality of water leakage holes 9 for discharging the residual liquid at the joint of the converging section and the lifting section of the mixing hopper 334 are arranged at the joint. In this way, the liquid can flow from the converging section to the lifting section during filling without affecting the discharge of the liquid, and the residual liquid can be completely discharged during the switching of the production products, reducing the impact on the subsequent products.

[0044] In an embodiment, the positioning assembly 34 includes a positioning cover 341 for positioning the mouth of the container. The positioning cover 341 is provided with a second through hole 342 for the head cover 32 to pass through the positioning cover 341 and insert into the container. In this way, the movement of the container is limited by the positioning cover 341, so that the container remains stable during filling, and the filling tube 31 can be accurately inserted into the container.

[0045] In an embodiment, the linkage assembly 35 includes a guide rod 351 arranged on the top of the positioning cover 341. The guide rod 351 is fixedly provided with two limiting rings 352. The guide rod 351 is provided with a sliding sleeve 353 that can move up and down along the guide rod 351. The sliding sleeve 353 is located between the two limiting rings 352, and the sliding sleeve 353 is fixedly connected with the filling tube 31.

[0046] When the sliding sleeve 353 is in contact with the upper limiting ring 352, the head cover 32 is located at the top of the positioning cover 341. When the sliding sleeve 353 is in contact with the lower limiting ring 352, the head cover 32 is located at the bottom of the positioning cover 341.

[0047] In this way, the positioning cover 341 can move with the movement of the filling tube 31, and will not hinder the movement of the container after filling. At the same time, when the positioning cover 341 is hindered by the container and cannot move downward, the filling tube 31 can still continue to move downward and insert into the container, avoiding the situation that the liquid leaks during filling.

[0048] In an embodiment, the extrusion assembly 36 comprises two vertical plates 361 arranged on the top of the positioning cover 341, the two vertical plates 361 are mirror symmetrical about the infusion tube 31, and each of the two vertical plates 361 is provided with an arc-shaped pressing block 362 on one side, the arc-shaped pressing block 362 is provided with a push rod 363 penetrating through the vertical plate 361 on the side away from the infusion tube 31, the push rod 363 is provided with a triangular prism 364 on the end away from the arc-shaped pressing block 362, and the push rod 363 is sleeved with a spring 365 between the triangular prism 364 and the vertical plate 361, and the extrusion assembly 36 further comprises two extrusion rods 366 for extruding the triangular prism 364;

[0049] The distance between the two arc-shaped pressing blocks 362 is greater than the outer diameter of the head cover 32 when the spring 365 is in a natural state, the distance between the two extrusion rods 366 is less than the maximum distance between the two triangular prisms 364 and greater than the minimum distance between the two triangular prisms 364 when the spring 365 is in a natural state, and the extrusion rod 366 is located on the top of the triangular prism 364 when the infusion tube 31 is in a filling state.

[0050] The head cover 32 is located between the two arc-shaped pressing blocks 362 when the sliding sleeve 353 is in contact with the upper limiting ring 352.

[0051] In this way, after the liquid in the container is filled, the infusion tube 31 first drives the head cover 32 to move between the two arc-shaped pressing blocks 362, and then the continuous upward movement of the infusion tube 31 drives the positioning cover 341 to move upward, so that the triangular prism 364 moves upward and passes the extrusion rod 366, and in the process of moving upward, the triangular prism 364 is pushed by the extrusion rod 366 and moves to the side close to the infusion tube 31, so that the arc-shaped pressing block 362 is pushed by the push rod 363 and extrudes the head cover 32, and the liquid in the head cover 32 is discharged and falls into the container below, ensuring that the head cover 32 has enough space to absorb the residual liquid from the infusion tube 31. The extrusion process and the filling process are combined, and the filling time is not affected.

[0052] In a specific implementation, after the arc-shaped pressing block 362 extrudes the head cover 32, part of the liquid is left on the surface of the arc-shaped pressing block 362. In order to avoid the liquid from falling, and to make the arc-shaped pressing block 362 fit the head cover 32 more closely during extrusion, the side of the arc-shaped pressing block 362 close to the infusion tube 31 is provided with a sponge pad.
