Description
Technical Field
[0001] This utility model relates to the technical field of feed additive filling equipment, and in particular to a liquid feed additive filling equipment. Background Technology
[0002] Feed additives refer to small or trace amounts of substances added during feed production, processing, and use. Although the amount used is small, they play an important role in animal growth and development, feed utilization, disease resistance, and the quality of livestock products. Additives are selected based on animal species, growth stage, physiological state, and feed ingredient characteristics. However, after the liquid feed additives are produced, they need to be filled into storage bottles and sealed using filling equipment.
[0003] A search revealed Chinese patent publication number CN221341324U, which discloses a feed additive packaging equipment, including a filling machine body. The filling machine body has symmetrically fixed rods at its outlet, and two fixed rods are fixedly connected to the same connecting cylinder at their bottom ends. Connecting rods are equidistantly fixed to the inner wall of the connecting cylinder, and one end of each connecting rod is fixedly connected to the same slide rail. Moving rods are equidistantly slidably embedded in the outer wall of the connecting cylinder, and tension springs are sleeved on the outer side of each moving rod. This invention allows the outer wall of the positioning rod to contact the outer wall of the connecting plate, facilitating the restriction of the position of the limiting plate. The device allows the outer packaging bag opening to be placed on top of the slide rail. The reaction force of the tension spring facilitates the sliding of the moving plate inside the connecting plate, causing multiple connecting plates to move away from the outer wall of the connecting cylinder. This restricts the opening of the packaging bag against the outer wall of the slide rail, thus providing support and limiting the opening position for easy material pouring. However, in actual use, while the device uses the restricting plate to limit the filling of the object, insufficient sealing during the filling process can cause the liquid feed additive to come into contact with air, leading to oxidation and spoilage. Utility Model Content

A mounting plate is rotatably connected to the top of the rotating shell. Two fixed arc plates are provided on the rear side of the mounting plate. The rear side of the mounting plate is fixedly installed to the front side of the front fixed arc plate. Cooling pipes are fixedly installed on the inner wall of the fixed arc plates. Connecting valves are respectively connected to the opposite sides of the two cooling pipes. Connecting components are provided on the outer walls of the two fixed arc plates.
[0012] The above technical solution enables the rotating shell to swing synchronously under the drive of the swing cylinder, allowing the fixed arc plate on the front side to swing back and forth, thereby achieving the effect of driving the fixed arc plate to fix the filling surface. Subsequently, an external water pump is connected through a connecting valve, allowing the coolant to circulate in the cooling pipe, thereby effectively stabilizing the internal temperature of the filling bottle. At the same time, the connection of the connecting components effectively improves the stability of the filling bottle.

Two connecting plates are fixedly connected to the rear side of the middle of the top wall of the base, and the front sides of the two connecting plates are fixedly connected to the rear side of the rear fixed arc plate.
[0015] The above technical solution enables the rear end of the locking plate to engage with the corresponding locking groove when the locking plate is flipped, thereby achieving the effect of connecting two fixed arc plates.
[0016] As a further description of the above technical solution:
[0017] A control switch is fixedly connected to the left side of the vertical shell on the left side. The control switch is electrically connected to the electric push rod, the negative pressure fan, the hydraulic rod and the swing cylinder respectively.
[0018] The above technical solution enables the device to be turned on and off by connecting the control switch.
[0019] As a further description of the above technical solution:
[0020] The sealing mechanism also includes two rubber rings, the inner walls of which are respectively fixedly connected to the bottom of the outer wall of the corresponding extraction tube.
[0021] The above technical solution reduces wear at the bottom connection of the extraction tube by using a rubber ring connection.
[0022] As a further description of the above technical solution:
[0023] The support assembly includes multiple support seats, with adjacent sides of the multiple support seats fixedly connected to the left and right sides of the base, and a support column fixedly connected inside the support seat.

[0025] As a further description of the above technical solution:
[0026] The fixing mechanism also includes multiple sealing rings, the inner walls of which are respectively fixedly connected to the outer walls of the corresponding connecting valves, and the outer walls of the sealing rings are fixedly connected to one side of the fixing arc plate.
[0027] The above technical solution enables the sealing effect between the connecting valve and the cooling pipe to be reduced by connecting multiple sealing rings.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the filling head can be initially adjusted to the filling height by raising and lowering the lifting plate.

This ensures the sealing of the connection between the filling bottle and the filling head, thereby reducing the contact between the feed additive and the outside air.
[0030] 2. In this utility model, the swing cylinder drives the rotating shell to swing, thereby displacing the fixed arc plate on the front side to the rear side, achieving the effect of fixing the filling bottle.

At the same time, the connection of the connecting component effectively improves the stability of the filling bottle and reduces the occurrence of filling problems. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a liquid feed additive filling device, including a base 1. Vertical shells 2 are fixedly connected to the left and right sides of the top wall of the base 1, supporting and installing a lifting mechanism 3 and a sealing mechanism 4. The lifting mechanism 3 is located inside the vertical shell 2, and a sealing mechanism 4 is located on one side of the lifting mechanism 3. The sealing mechanism 4 is used to adjust the filling height. A fixing mechanism 5 is located in the middle of the top wall of the base 1 for fixing the filling bottles. Support components 7 are located on the left and right sides of the outer wall of the base 1. The sealing mechanism 4 includes a lifting plate 401, which allows the lifting plate 401 to move during lifting... Driven by mechanism 3, the height can be adjusted. The outer wall of the lifting plate 401 is located in the middle of the vertical shell 2. Electric push rods 402 are fixedly connected to the left and right sides of the top wall of the lifting plate 401. A fixed shell 403 is fixedly connected to the top wall of the electric push rod 402. A feeding pipe 404 is fixedly connected to the inner wall of the fixed shell 403. The rear end of the feeding pipe 404 is connected to the filling equipment, enabling the filling of additives. A filling head 405 is fixedly installed at the bottom end of the feeding pipe 404. The installation or removal of the filling head 405 facilitates cleaning and maintenance of its interior. The middle of the top wall of the lifting plate 401 is fixedly connected to... A negative pressure fan 406 is connected, with extraction pipes 407 connected to both the left and right sides of the front end of the negative pressure fan 406. The bottom end of the extraction pipes 407 is connected to a sealing sleeve 408. When the negative pressure fan 406 is activated, airflow is extracted through the extraction pipes 407, thereby drawing out the air inside the sealing sleeve 408 and compressing the space inside the sealing sleeve 408. This improves the sealing performance at the connection between the filling head 405 and the filling bottle, reducing the risk of additive deterioration due to contact with outside air. The top of the inner wall of the sealing sleeve 408 engages with the bottom end of the filling head 405. The lifting mechanism 3 includes two... The outer walls of the two limiting shells 301 are fixedly connected to the inner walls of the corresponding vertical shells 2. The bottom inner wall of the vertical shell 2 is fixedly connected to a hydraulic rod 302, so that when the hydraulic rod 302 is activated, its top end can lift the multi-functional fixing plate 303. The top end of the hydraulic rod 302 is fixedly connected to the fixing plate 303. The outer wall of the fixing plate 303 is slidably connected to the inside of the limiting shell 301, so that the fixing plate 303 drives the lifting plate 401 to lift and slide inside the limiting shell 301, ensuring the stability of the lifting. The outer wall of the lifting plate 401 is fixedly connected between the adjacent two fixing plates 303.
[0040] Specifically, the vertical shells 2 fixed to the left and right sides of the top wall of the base 1 provide support and installation foundation for the lifting mechanism 3 and the sealing mechanism 4. Inside the lifting mechanism 3, the outer walls of two limiting shells 301 are fixed to the inner wall of the vertical shell 2. After the hydraulic rod 302 on the bottom wall of the inner wall of the vertical shell 2 is activated, its top end drives the fixed plate 303 fixedly connected to it to rise and fall. Thus, the outer wall of the fixed plate 303 slides with the inside of the limiting shell 301 to ensure the stability of the lifting process. The outer wall of the lifting plate 401 is fixed between the two adjacent fixed plates 303. Thus, under the drive of the fixed plate 303, the lifting plate 401 synchronously rises and slides inside the limiting shell 301 to complete the filling height adjustment. The lifting plate 401 of the sealing mechanism 4 changes height under the drive of the lifting mechanism 3. The electric push rods 402 on the left and right sides of its top wall can drive the fixed plate 301 to rise and fall. The fixed shell 403 and its internal feeding pipe 404 are raised and lowered. The rear end of the feeding pipe 404 is connected to the filling equipment to realize the filling of additives. The filling head 405 at the bottom of the feeding pipe 404 is easy to disassemble, clean and maintain. After the negative pressure fan 406 in the middle of the top wall of the lifting plate 401 is started, air is drawn out through the extraction pipe 407 connected to the left and right sides of the front end. The air inside the sealing sleeve 408 connected to the bottom end of the extraction pipe 407 is drawn out, the space is compressed, and the top of the inner wall of the sealing sleeve 408 is tightly locked with the bottom end of the filling head 405, which enhances the sealing of the connection between the filling head 405 and the filling bottle, reduces the contact between the additive and the outside air, and avoids the deterioration of the additive. The fixing mechanism 5 in the middle of the top wall of the base 1 is used to fix the filling bottle, and the support components 7 on the left and right sides of the outer wall provide additional support for the overall structure.
[0041] Reference Figure 1 , Figure 2 and Figure 5The fixing mechanism 5 includes two upright plates 501. The bottom walls of the two upright plates 501 are respectively fixedly connected to the left and right sides of the inner bottom wall of the base 1. A swing cylinder 502 is fixedly connected to the outer wall of each upright plate 501 on the opposite side, allowing the rotating shell 503 to swing under the drive of the swing cylinder 502. A rotating shell 503 is fixedly connected to the adjacent side of each of the two swing cylinders 502. A mounting plate 504 is rotatably connected to the top of the rotating shell 503, allowing the fixed arc plate 505 mounted on the mounting plate 504 to swing synchronously. This, in conjunction with the fixed arc plate 505 fixed to the rear side via the connecting plate 5093, enables the fixing and clamping of the filling bottle. Two fixed arc plates 505 are provided on the rear side of the mounting plate 504, and the rear side of the mounting plate 504 is fixedly installed to the front side of the front fixed arc plate 505. A cooling pipe 506 is fixedly installed on the inner wall of the fixed arc plate 505, thereby connecting the connecting valve 507 to an external water pump, enabling it to... The circulating coolant flows inside the cooling pipe 506, ensuring the temperature balance of the filling bottle. The two cooling pipes 506 are connected to the opposite sides of each other by a connecting valve 507. The outer walls of the two fixed arc plates 505 are provided with connecting components 509. The connecting components 509 include multiple locking plates 5091. The adjacent sides of the multiple locking plates 5091 are rotatably connected to the left and right sides of the front fixed arc plate 505, so that when the locking plates 5091 rotate, they engage with the locking grooves 5092 on the rear side, so that the multiple fixed arc plates 505 on the front side can lock with the fixed arc plate 505 on the rear side. The left and right sides of the multiple fixed arc plates 505 on the rear side are provided with locking grooves 5092. The rear ends of the multiple locking plates 5091 engage with the corresponding locking grooves 5092. Two connecting plates 5093 are fixedly connected to the rear side of the middle of the top wall of the base 1. The front sides of the two connecting plates 5093 are fixedly connected to the rear side of the rear fixed arc plate 505.
[0042] Specifically, two vertical plates 501 on the left and right sides of the inner bottom wall of the base 1 have swing cylinders 502 installed on their outer walls on opposite sides. The swing cylinders 502 drive the rotating shell 503 on the adjacent side to swing, and the mounting plate 504 rotatably connected to the top of the rotating shell 503 swings accordingly. This causes the front fixed arc plate 505 fixed to the rear side of the mounting plate 504 to swing synchronously. This, in conjunction with the rear fixed arc plate 505 fixed to the middle rear side of the top wall of the base 1 via a connecting plate 5093, achieves the fixed clamping of the filling bottle. A cooling pipe 506 is installed on the inner wall of the fixed arc plate 505 on the rear side of the mounting plate 504. A connecting valve 507 connected to the opposite side of the pipe 506 is connected to an external water pump, which can circulate coolant into the cooling pipe 506. Through the heat exchange of the coolant, the temperature of the filling bottle is maintained. To balance and prevent temperature changes from affecting the filling process or material properties, multiple locking plates 5091 are rotatably connected to the left and right sides of the front fixed arc plate 505 in the connecting assembly 509 on the outer wall of the fixed arc plate 505. Locking grooves 5092 are opened on the left and right sides of the rear fixed arc plate 505. When the swing cylinder 502 drives the front fixed arc plate 505 to approach the rear fixed arc plate 505, the locking plate 5091 is rotated so that its rear end is locked into the corresponding locking groove 5092, thus locking the front and rear fixed arc plates 505 and ensuring that the filling bottle is firmly clamped. This structure achieves stable clamping and temperature control of the filling bottle through the drive of the swing cylinder 502, the temperature regulation of the cooling pipe 506, and the locking mechanism of the connecting assembly 509, ensuring the accuracy and stability of the filling operation.
[0043] Reference Figure 1 , Figure 2 and Figure 3 The sealing mechanism 4 also includes two rubber rings 409, the inner walls of which are fixedly connected to the bottom of the outer wall of the corresponding extraction tube 407; a control switch 6 is fixedly connected to the left side of the left vertical shell 2, and the control switch 6 is electrically connected to the electric push rod 402, the negative pressure fan 406, the hydraulic rod 302 and the swing cylinder 502 respectively.
[0044] Specifically, the connection of the rubber ring 409 protects the connection of the extraction tube 407, thereby improving its service life. The control switch 6, which is electrically connected to the electric push rod 402, the negative pressure fan 406, the hydraulic rod 302 and the swing cylinder 502 respectively, enables the equipment to be turned on and off.
[0045] Reference Figure 1 , Figure 4 and Figure 5The support assembly 7 includes multiple support seats 701, with adjacent sides of the multiple support seats 701 respectively fixedly connected to the left and right sides of the base 1, and a support column 702 fixedly connected inside the support seat 701; the fixing mechanism 5 also includes multiple sealing rings 508, with the inner walls of the multiple sealing rings 508 respectively fixedly connected to the outer walls of the corresponding connecting valves 507, and the outer walls of the sealing rings 508 fixedly connected to one side of the fixing arc plate 505;
[0046] Specifically, the connection between the support base 701 and the support column 702 improves the lateral stability of the device during operation and ensures the filling effect. The sealing ring 508 can seal the connection between the connecting valve 507 and the cooling pipe 506, thereby improving the sealing performance.
[0047] Working principle: The hydraulic rod 302, when activated, drives the fixed plate 303 to slide within the limiting shell 301, simultaneously raising and lowering the lifting plate 401. This achieves initial height adjustment of the filling head 405. The electric push rod 402 of the sealing mechanism 4 pushes the fixed shell 403 and the feeding pipe 404 to rise and fall, reducing the impact of bending of the feeding pipe 404 on filling. The rear end of the feeding pipe 404 connects to the injection equipment, enabling filling operations. The filling head 405 at the bottom can be disassembled for cleaning and maintenance. Subsequently, the negative pressure fan 406... When activated, the air inside the sealing sleeve 408 can be extracted through the extraction tube 407, compressing the internal space of the sealing sleeve 408. The top of its inner wall is tightly engaged with the bottom of the filling head 405, and the bottom is connected to the filling bottle, improving the sealing performance of the connection between the filling head 405 and the filling bottle, reducing the contact between the feed additive and the outside air, and preventing deterioration. The support components 7 on the left and right sides of the outer wall provide structural support, enabling the completion of filling height adjustment, sealing guarantee and filling bottle fixation, ensuring the stability of the feed additive filling process and product quality.
[0048] Furthermore, by activating the swing cylinder 502, the rotating shell 503 is driven to swing, causing the mounting plate 504 rotatably connected to the top of the rotating shell 503 to move accordingly. This causes the front fixed arc plate 505, fixed to the rear side of the mounting plate 504, to move rearward. Simultaneously, the rear fixed arc plate 505, fixed to the rear side of the middle of the top wall of the base 1 via the connecting plate 5093, remains stationary. The front and rear fixed arc plates 505 cooperate to achieve the fixed clamping operation of the filling bottle. The cooling pipe 506 installed on the inner wall of the fixed arc plate 505 is connected to an external water pump through a connecting valve 507 connected to the opposite side. After the water pump is started, the coolant circulates in the cooling pipe 506, carrying away or replenishing the filling bottle through heat exchange. The heat generated during bottling maintains the temperature balance of the filled bottles, preventing temperature changes from affecting the filling process or material quality. In the connecting assembly 509 on the outer wall of the fixed arc plate 505, multiple locking plates 5091 are rotatably connected to the left and right sides of the front fixed arc plate 505 on adjacent sides. The left and right sides of the rear fixed arc plate 505 are provided with locking grooves 5092. After the front fixed arc plate 505 has finished clamping the filled bottle, the locking plate 5091 is rotated so that its rear end is locked into the corresponding locking groove 5092, locking the front and rear fixed arc plates 505. This enhances the fixing effect of the fixed arc plate 505 on the filled bottle, reduces the risk of filling abnormalities caused by bottle shaking or displacement during the filling process, and ensures that the filling work is carried out stably and efficiently.
