Description

Technical Field

[0001] The utility model relates to the technical field of feed additive filling equipment, in particular to liquid feed additive filling equipment. Background Art

[0002] Feed additives refer to small or trace substances added during the production, processing and use of feed. They come in liquid and solid forms. They are a kind of nutritional supplement that combines the trace elements, vitamins, antioxidants, organic growth promoters and disease-resistant substances required for the growth and development of livestock and poultry. Although their dosage in feed is very small, their effect is very significant. Feed additives are raw materials that must be used in the modern feed industry. They have obvious effects on enhancing the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of livestock products.

[0003] However, after the production of liquid feed additives is completed, it is necessary to fill the liquid feed additives into the storage bottle through a filling device for sealing.

In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.

[0022] Combination Figure 1 , Figure 2 and Figure 3As shown, a plurality of filling heads 11 are evenly arranged on the filling machine 1, and a limiting frame 2 is arranged on the side wall of the filling machine 1 around the outside of the plurality of filling heads 11, and the limiting frame 2 includes a top plate 21 and a bottom plate 22, wherein the top plate 21 is arranged above the plurality of filling heads 11, and a cylinder 12 is arranged on the side wall of the filling machine 1 above the top plate 21, and an extension rod 121 is arranged at the output end of the cylinder 12, and the end of the extension rod 121 away from the cylinder 12 is installed on the upper end surface of the top plate 21, and the bottom plate 22 is arranged below the plurality of filling heads 11, and positioning rods 23 are respectively arranged at the top two ends of the bottom plate 22, and the positioning rod 23 is away from the bottom plate 22. One end of the plate 22 passes through the top plate 21 and extends above it. The outer wall of the positioning rod 23 located above and below the top plate 21 is provided with an annular limit plate 24 for limiting its position. A buffer spring 25 is provided between the upper end surface of the annular limit plate 24 located below the top plate 21 and the lower end surface of the top plate 21 and around the outside of the positioning rod 23. A first sliding hole 211 is also provided at the position corresponding to the end surface of the top plate 21 and the positioning rod 23. The positioning rod 23 is slidably installed in the inside of the first sliding hole 211 and extends to the top of the top plate 21. The end surface area of ​​the annular limit plate 24 is larger than the opening area of ​​the first sliding hole 211.

[0023] In one embodiment, when the limit frame 2 is driven to move, the extension rod 121 installed at its output end can be driven to extend through the cylinder 12, so that the extension rod 121 pushes the limit frame 2 installed thereon to move downward, and then the bottom plate 22 at the bottom of the limit frame 2 drives the protective tube 3 installed thereon to move downward, so that the protective tube 3 moves downward outside the filling head 11 and covers the outside of the opening of the storage bottle. At the same time, after the protective tube 3 contacts the storage bottle, it stops moving due to resistance, and drives the bottom plate 22 connected thereto to stop moving, so that The top plate 21 pushed by the extending rod 121 slides on the outer wall of the positioning rod 23 through the first sliding hole 211 and squeezes the buffer spring 25 to deform it. The buffer spring 25 buffers the pressing force of the top plate 21 through its own elastic force, preventing the top plate 21 from directly pressing on the annular limiting plate 24, allowing the annular limiting plate 24 to push the bottom plate 22 through the positioning rod 23 to continue moving and pressing the storage bottle, thereby avoiding the situation where the storage bottle is crushed due to the continuous force displacement of the bottom plate 22 pressing the storage bottle, thereby protecting the storage bottle.

[0024] In one embodiment, since the end surface area of ​​the annular limit plate 24 is larger than the opening area of ​​the first sliding hole 211, when the limit frame 2 is not in use, the annular limit plate 24 can be used to limit the positions of the bottom plate 22 and the positioning rod 23 to prevent the bottom plate 22 and the positioning rod 23 from detaching from the top plate 21, thereby ensuring the use of the limit frame 2.

[0025] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a protective cylinder 3 is slidably installed at the top of the bottom plate 22 and at positions corresponding to the plurality of filling heads 11. A cavity 301 is provided inside the protective cylinder 3. An annular mounting frame 33 is threadedly installed on the inner wall of the cavity 301. One end of the annular mounting frame 33 is sleeved on the outside of the filling head 11, and an extension tube 34 is provided at the middle position of the other end. One end of the extension tube 34 located inside the annular mounting frame 33 is sleeved on the outside of the filling tube of the filling head 11 and is connected to the extension tube 34. The extension tube 34 is away from the annular mounting frame 33. One end of the mounting frame 33 passes through the protective tube 3 and extends to the bottom thereof, and annular end plates 31 are provided at the upper and lower ends of the outer wall of the protective tube 3 at the bottom plate 22, and return springs 32 are provided between the end surfaces of the two annular end plates 31 close to one end of the top plate 21 and the top plate 21 and around the outside of the protective tube 3, and a plurality of through holes 302 are evenly opened on the outer wall of the protective tube 3 at the side away from the two annular end plates 31, and the cavity 301 is connected to the external air through the through holes 302.

[0026] In one embodiment, when using the protective tube 3, the protective tube 3 can first be allowed to follow the displacement of the bottom plate 22 and move downward outside the filling head 11 and cover the outside of the opening of the storage bottle to prevent the liquid feed additive from splashing outside the bottle and causing waste. The protective tube 3 then drives the extension tube 34 installed inside it to slide downward on the outer wall of the filling tube on the filling head 11 and extend from the opening of the storage bottle into the bottle, and the liquid feed flowing out of the filling tube on the filling head 11 is added and transported to the storage bottle, so as to fill the liquid feed additive into the storage bottle, and allow the air in the storage bottle to be discharged from the empty groove 334 in the annular mounting frame 33 and the through hole 302 on the protective tube 3 to the outside of the protective tube 3, so that the filling of the liquid feed additive is not affected by the air pressure in the storage bottle, thereby ensuring the progress of the liquid feed additive filling work.

[0027] In one embodiment, when the protective tube 3 moves downward outside the filling head 11 following the displacement of the bottom plate 22, the protective tube 3 can first contact the storage bottle through the rubber pad 35, and then the protective tube 3 can be displaced upward in the second slide hole 221 under the reaction force after the protective tube 3 contacts the storage bottle, and drive the annular end plate 31 installed thereon to press the reset spring 32 to deform, and the reset spring 32 buffers the pressure of the protective tube 3 to prevent the storage bottle from being damaged by a large pressure, thereby achieving double protection for the storage bottle.

[0028] In one embodiment, when the extension tube 34 is installed in the protective tube 3 for use, one end of the extension tube 34 can be first inserted into the cavity 301, and then the upper fixing ring 331 and the lower fixing ring 332 on the annular mounting frame 33 are screwed through the threaded groove 303, and the upper fixing ring 331 and the lower fixing ring 332 connected by the connecting rod 333 are installed on the inner wall of the cavity 301, so that the lower fixing ring 332 drives the extension tube 34 installed thereon to move downward in the cavity 301 and extend out of the protective tube 3, thereby completing the assembly of the protective tube 3 and the extension tube 34, and the extension tube 34 can be installed inside the protective tube 3, so that the empty groove 334 between the annular mounting frame 33 and the extension tube 34 is connected to the external air through the through hole 302, so that the air in the storage bottle can be discharged from the empty groove 334 in the annular mounting frame 33 and the through hole 302 on the protective tube 3 to the outside of the protective tube 3, thereby facilitating the filling of liquid feed additives.

[0029] The working principle of the utility model is as follows: when filling the liquid feed additive, the extension rod 121 installed at the output end thereof can be driven to extend through the cylinder 12, so that the extension rod 121 pushes the limit frame 2 installed thereon to move downward, and then the bottom plate 22 at the bottom of the limit frame 2 drives the protective tube 3 installed thereon to move downward, so that the protective tube 3 moves downward outside the filling head 11 and covers the outside of the opening of the storage bottle to prevent the liquid feed additive from splashing outside the bottle and causing waste, and then the protective tube 3 drives the extension tube 34 installed inside it to slide downward on the outer wall of the filling tube on the filling head 11 and extend from the opening of the storage bottle into the bottle, so that the liquid feed additive from the filling head 11 is filled. The liquid feed flowing out of the tube is added and transported to the storage bottle, and the air in the storage bottle is discharged to the outside of the protective tube 3 from the empty groove 334 in the annular mounting frame 33 and the through hole 302 on the protective tube 3, so that the liquid feed additive is filled into the storage bottle, and the air in the bottle can be discharged while preventing the liquid feed additive from splashing out of the bottle and causing waste, so that the filling of the liquid feed additive is not affected by the air pressure in the storage bottle, and avoids the situation that the air in the bottle needs to be discharged before the liquid feed additive can be filled into the bottle due to the storage bottle being blocked to prevent the liquid feed additive from splashing out of the bottle during filling, thereby saving time and effort and improving the filling efficiency.
