Description

Technical Field

[0001] This invention relates to the field of beer bottling technology, and more specifically to an auxiliary device for bottling beer. Background Technology

[0002] Bottling beer kegs is a crucial step in the beer production process, and its quality directly affects the beer's freshness, taste, and shelf life. Traditional bottling equipment typically uses a simple filling gun inserted directly into the keg opening. This process is prone to problems such as air entering or carbon dioxide escaping due to inadequate sealing, leading to beer oxidation, excessive foam, or insufficient carbonization.

[0003] To ensure that there is no leakage, oxidation, or foam overflow during the filling process, existing technologies often improve the sealing effect by adding sealing rings or fixing clamps. However, the sealing method is mostly static compression sealing, which is difficult to adapt to the slight dimensional differences of the openings of different sizes of barrels, and the accumulation of tolerances can easily lead to incomplete sealing.

[0004] Therefore, it is necessary to design a keg beer filling auxiliary device with dynamic sealing capability and adaptability to different keg opening sizes to solve the above-mentioned technical problems. Summary of the Invention

[0005] The technical solution is as follows: A keg beer filling auxiliary device includes a base, a stand, a first electric screw assembly, a lifting frame, and a filling gun. The stand is mounted on the top of the base, and the lifting frame is slidably mounted at the opening of the stand. A first electric screw assembly for driving the lifting frame to rise and fall is installed inside the stand. A filling gun for filling beer into the keg is mounted on the lifting frame. The device also includes a first guide rod, a filling sealing disc, a first return spring, a filling sealing column, a filling sealing cover, a top rod, a second drive assembly, and a driven gear ring. First guide rods are symmetrically slidably mounted on the horizontal plates on both sides of the lifting frame. The lower ends of the first guide rods are connected to the filling sealing disc, and a first return spring is provided between the upper ends of the first guide rods and the horizontal plates of the lifting frame. The filling sealing disc has a circular groove at its center, and a filling sealing column is installed in the circular groove. The filling sealing column is vertically continuous. A driven gear ring and a second drive assembly for driving the driven gear ring to rotate are rotatably arranged inside the filling sealing column. The filling gun is located above the driven gear ring. A filling sealing cover for fitting against the outer wall of the bottle mouth is connected to the bottom of the driven gear ring. The filling sealing disc has evenly spaced circumferential grooves inside. A push rod is slidably arranged in the grooves. One end of the push rod slides through the filling sealing column and connects to the lower part of the filling sealing cover. The filling sealing disc is provided with a drive component for driving the push rod to move along the grooves towards the center of the filling sealing disc so that the lower inner wall of the filling sealing cover fits tightly against the outer wall of the bottle mouth.

[0006] Preferably, the driving component is a driven gear disk rotatably mounted in the inner cavity of the filling sealing disk and a first driving assembly for driving the driven gear disk to rotate. The driven gear disk has annularly arranged arc-shaped grooves, and the push rod slides through the arc-shaped grooves.

[0007] Preferably, a sealing cap is provided at the top of the filling and sealing column, and the filling gun is located inside the sealing cap.

[0008] Preferably, the lower part of the filling gun is provided with a fixed cover, the bottom of the fixed cover is open, and a second guide rod is arranged in a circumferential array on the fixed cover with the filling gun as the center. The lower end of the second guide rod is connected to an adsorption component for adsorbing beer foam, and a second return spring is provided between the upper end of the second guide rod and the top wall of the fixed cover.

[0009] Preferably, the adsorption assembly includes a first sponge block, an adsorption ring, and a second sponge block arranged sequentially from top to bottom. The first sponge block is connected to the lower end of the second guide rod, the second sponge block is detachably disposed at the bottom of the first sponge block, and the adsorption ring is disposed between the second sponge block and the first sponge block. Both the first sponge block and the second sponge block are porous sponges.

[0010] Preferably, a suction tube is connected to the adsorption ring.

[0011] Preferably, a U-shaped mounting bracket is installed at the bottom of the base, and a second electric screw assembly is provided on the U-shaped mounting bracket and a lifting plate is movably connected to the second electric screw assembly. The lifting plate is located below the base, and hinges are hinged at both ends of the lifting plate. A column is symmetrically rotated on the top of the base, and the end of the hinge away from the lifting plate is hinged to the column. A clamping ring for clamping the tank is provided on the column.

[0012] Preferably, a positioning screw is provided on the front side of the support frame, and the top of the positioning screw is on the same plane as the junction of the bottle mouth and the bottle body.

[0013] The beneficial effects of this invention are as follows: 1. The driven gear disk is driven to rotate by the first driving component, thereby pushing the push rod to retract towards the center along the radial sliding groove of the filling sealing disk through the arc groove. The push rod then applies a squeezing force to the filling sealing cover, causing the lower part of the filling sealing cover to radially tighten the lower part of the outer wall of the bottle mouth. The driven gear ring is driven to rotate by the second driving component, thereby causing the upper part of the filling sealing cover to circumferentially twist. This achieves a full-range, no-dead-angle dynamic sealing and wrapping of the bottle mouth, thus adapting to bottle mouths of different diameters and forming a nearly completely sealed filling environment, thereby ensuring the quality of beer.

[0014] 2. When the filling gun is inserted into the can to fill beer, the beer foam coming out of the bottle mouth is absorbed by the adsorption assembly consisting of the first sponge block, the adsorption ring and the second sponge block. After filling, the filling nozzle of the filling gun is wiped by the adsorption assembly to prevent beer foam from remaining on the filling nozzle of the filling gun, thereby achieving the effect of cleaning the filling nozzle of the filling gun.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example: A keg beer filling auxiliary device, such as Figures 1-5 As shown, the device includes a base 1, a support frame 2, a first electric screw assembly 3, a lifting frame 4, and a filling gun 5. The support frame 2 is mounted on the top rear side of the base 1. The lifting frame 4 is slidably mounted at the upper opening of the support frame 2 and is slidably mounted on the front side of the support frame 2. The first electric screw assembly 3 for driving the lifting frame 4 to rise and fall is installed inside the support frame 2. The first electric screw assembly 3 includes a first screw rotatably mounted inside the support frame 2 and a first drive motor for driving the first screw to rotate. The filling gun 5 for filling beer into the can 100 is mounted on the lifting frame 4. The lower part of the filling gun 5 is a cylindrical filling nozzle and also includes a first guide rod 7. The lifting frame 4 consists of a filling sealing disc 8, a first return spring 9, a filling sealing column 10, a filling sealing cover 1001, a top rod 13, a second drive assembly 14, and a driven gear ring 15. First guide rods 7 are symmetrically slidably mounted on the horizontal plates on the left and right sides of the front part of the lifting frame 4. The lower ends of the first guide rods 7 are connected to the filling sealing disc 8. A first return spring 9 is positioned between the upper end of the first guide rod 7 and the horizontal plate of the lifting frame 4. The two ends of the first return spring 9 are connected to the upper end of the first guide rod 7 and the top of the horizontal plate of the lifting frame 4, respectively. The first return spring 9 is wound around the first guide rod 7 and is a tension spring. Figure 3 He Ru Figure 4The image shows the initial state of the first return spring 9; a circular through groove is provided at the center of the filling sealing disc 8, and a filling sealing column 10 is fixedly installed in the circular through groove. The filling sealing column 10 is vertically continuous, and a driven gear ring 15 and a second drive assembly 14 for driving the driven gear ring 15 to rotate are rotatably arranged in the middle inner cavity of the filling sealing column 10. The second drive assembly 14 includes a second motor installed on the outer wall of the middle part of the filling sealing column 10 and a second drive gear connected to the output shaft of the second motor. The second drive gear is located in the middle inner cavity of the filling sealing column 10 and meshes with the outer teeth of the driven gear ring 15. The second drive assembly 14 drives the driven gear ring 15 to perform a deceleration movement; filling gun 5 is located above the driven gear ring 15. The bottom of the driven gear ring 15 is connected to a filling sealing cover 1001 for fitting against the outer wall of the bottle mouth of the can 100. The filling sealing cover 1001 is made of rubber with elastic deformation capability. The inner ring of the filling sealing disk 8 has radial grooves 81 evenly spaced around its circumference. A push rod 13 is slidably arranged in the groove 81. One end of the push rod 13 slides through the filling sealing column 10 and connects with the lower part of the filling sealing cover 1001. The filling sealing disk 8 is provided with a driving component for driving the push rod 13 to move along the groove 81 towards the center of the filling sealing disk 8 so that the lower inner wall of the filling sealing cover 1001 is tightly attached to the outer wall of the bottle mouth of the can 100.

[0027] like Figure 4 and Figure 5 As shown, the driving components are a driven gear disk 12 rotatably mounted in the inner cavity of the filling sealing disk 8 and a first driving assembly 11 for driving the driven gear disk 12 to rotate. The first driving assembly 11 includes a first motor mounted on the top of the filling sealing disk 8 and a second driving gear connected to the output shaft of the first motor. The second driving gear is located in the inner cavity of the filling sealing disk 8 and meshes with the teeth on the outer circumferential wall of the driven gear disk 12. The first driving assembly 11 drives the driven gear disk 12 to perform a deceleration motion. The driven gear disk 12 is provided with an arc-shaped groove 121 arranged in a ring array. The number of arc-shaped grooves 121 is the same as the number of sliding grooves 81. The push rod 13 slides through the arc-shaped groove 121.

[0028] Furthermore, a miniature camera is installed inside the filling and sealing column 10 to monitor the movement of its internal components in real time. This auxiliary device is equipped with a display screen, and the data collected by the miniature camera is transmitted to the display screen in real time for real-time display, which provides convenience for staff to understand the internal situation of the filling and sealing column 10.

[0029] like Figure 3 As shown, a sealing cap 6 is provided on the top of the filling sealing column 10, and the filling gun 5 is located inside the sealing cap 6.

[0030] like Figure 6 and Figure 7As shown, a fixed cover 16 is provided at the lower part of the filling gun 5. The bottom of the fixed cover 16 is open, and the filling nozzle of the filling gun 5 extends into the bottom opening of the fixed cover 16. Second guide rods 17 are arranged in a circumferential array on the fixed cover 16 with the filling gun 5 as the center. The lower ends of the second guide rods 17 are connected to an adsorption component for adsorbing beer foam. A second return spring 19 is provided between the upper end of the second guide rod 17 and the top wall of the fixed cover 16. The two ends of the second return spring 19 are respectively connected to the upper end of the second guide rod 17 and the top wall of the fixed cover 16. The second return spring 19 is a compression spring, and its initial state is as follows: Figure 7 As shown, in the initial state, the adsorption assembly of the second reset spring 19 is located at the lower opening of the fixed cover 16.

[0031] like Figure 7 and Figure 8 As shown, the adsorption assembly includes a first sponge block 18, an adsorption ring 21, and a second sponge block 22 arranged sequentially from top to bottom. The first sponge block 18 is connected to the lower end of the second guide rod 17. The second sponge block 22 is detachably disposed at the bottom of the first sponge block 18. Both the first sponge block 18 and the second sponge block 22 are porous sponges. The adsorption ring 21 is disposed between the second sponge block 22 and the first sponge block 18. A suction tube 20 is connected to the adsorption ring 21. The center of the first sponge block 18, the second sponge block 22, and the adsorption ring 21 are all provided with through holes for the filling nozzle of the filling gun 5 to pass through. The diameter of the through holes is smaller than the diameter of the filling nozzle of the filling gun 5. The filling nozzle of the filling gun 5 forces downward through the holes in the first sponge block 18 and the second sponge block 22. When the filling nozzle of the filling gun 5 passes through the through hole of the adsorption ring 21 and the adsorption component 22, the adsorption assembly composed of the first sponge block 18, the second sponge block 22 and the adsorption ring 21 wipes the filling nozzle of the filling gun 5. After the filling nozzle of the filling gun 5 passes through the through hole of the adsorption assembly, it extends into the can 100 for filling. When the beer foam generated during the filling operation emerges from the bottle mouth of the can 100, the adsorption assembly adsorbs the beer foam in time and removes the adsorbed foam through the suction tube 20, thereby ensuring that the adsorption assembly maintains a stable adsorption capacity. After filling is completed, as the filling nozzle of the filling gun 5 moves upward away from the adsorption assembly, the adsorption assembly adsorbs the beer foam on the filling nozzle of the filling gun 5 to prevent the beer foam from adhering to the outer wall of the filling nozzle of the filling gun 5. like Figure 9As shown, a U-shaped mounting bracket 23 is installed at the bottom of the base 1. A second electric screw assembly 25 is provided on the U-shaped mounting bracket 23, and a lifting plate 24 is movably connected to the second electric screw assembly 25. The lifting plate 24 is located below the base 1. The second electric screw assembly 25 includes a second drive motor installed on the U-shaped mounting bracket 23 and a second screw connected to the output shaft of the motor. The second screw rotates through the U-shaped mounting bracket 23 and then rotates to connect with the base 1. The second screw thread passes through the lifting plate 24. The two ends of the lifting plate 24 are hinged with hinge members 26. A column 27 is symmetrically and rotatably provided on the top of the base 1. The end of the hinge member 26 away from the lifting plate 24 is hinged to the column 27. A clamping ring 28 for clamping the tank 100 is provided on the column 27.

[0032] like Figure 1 and Figure 3 As shown, a positioning screw 201 is threaded on the front side of the support frame 2, and the top of the positioning screw 201 is on the same plane as the junction of the bottle mouth and the bottle body of the tank 100.

[0033] In use, the beer barrel (can 100) to be filled is first placed on the base 1. The second electric screw assembly 25 drives the lifting plate 24 to move downward. The lifting plate 24 pulls the two columns 27 through the hinges 26 at both ends, rotating them inward around the hinge point with the base 1. The clamping ring 28 then moves closer to the can 100 and finally clamps it onto the outer wall of the can 100, thus achieving the effect of firmly holding and fixing the can 100 from both sides, preventing the can 100 from shaking or tipping over during the filling process. After the can 100 is fixed, the first electric screw assembly 3 is activated, driving the entire lifting frame 4 to move downward along the frame 2. The filling gun 5 and the filling sealing plate installed on the lifting frame 4... 8. The filling sealing column 10 and other filling components descend synchronously with the lifting frame 4. During the descent, the circular groove of the filling sealing disc 8 first passes through the bottle neck of the beer barrel (can body 100) and contacts the bottle body. The filling sealing cover 1001 gradually forms a state that surrounds and wraps around the bottle neck of the beer barrel (can body 100). When the bottom of the filling sealing disc 8 descends to contact the top of the positioning screw 201, which has been pre-adjusted in height by screwing, the filling sealing disc 8 is blocked by the positioning screw 201 and stops moving downward. The filling sealing disc 8, the filling sealing column 10, the filling sealing cover 1001, the first drive assembly 11, the driven gear disc 12, the push rod 13, the second drive assembly 14, and the driven gear ring 15 are connected. When stationary, the first electric screw assembly 3 continues to drive the lifting frame 4 downward. Since the filling sealing disc 8 has been positioned, the horizontal plate of the lifting frame 4 will continue to move downward relative to the stationary filling sealing disc 8 along the first guide rod 7. The first return spring 9 is stretched, accumulating return force. The filling gun 5, along with its surrounding fixed cover 16 and adsorption assembly, which move downward with the lifting frame 4, also descend. The adsorption assembly gradually contacts the top of the bottle opening of the tank 100. As the lifting frame 4 continues to move downward, the adsorption assembly is completely pressed into the fixed cover 16, and the second return spring 19 is stretched until the fixed cover 16 contacts the bottle opening of the tank 100, and the filling nozzle of the filling gun 5 extends into the bottle opening of the tank 100 to a certain depth. At this time, the first electric lead screw assembly 3 stops working, the lifting frame 4 remains in its current position, and the fixed cover 16 has been lowered into the filling sealing cover 1001; then, the first drive assembly 11 works, thereby driving the driven gear disk 12 to rotate clockwise. The arc-shaped grooves 121 in the annular array on the driven gear disk 12 rotate with the driven gear disk 12. As the push rods 13 slide through these arc-shaped grooves 121, the groove walls will push all the push rods 13 to retract towards the center along the radial sliding grooves 81 of the filling sealing disk 8. The push rods 13 then apply a squeezing force to the filling sealing cover 1001, so that the lower part of the filling sealing cover 1001 is tightly attached to the lower outer wall of the bottle neck of the beer barrel (can body 100).Subsequently, the driven gear ring 15 is driven to rotate by the second drive assembly 14. When the driven gear ring 15 drives the upper part of the filling sealing cover 1001 to rotate, the lower part of the filling sealing cover 1001 is fixed while the upper part rotates, causing the middle part of the filling sealing cover 1001 to twist and deform. This twisting causes the filling sealing cover 1001 to tightly wrap the inner fixing cover 16 and the bottle mouth of the can 100, thereby keeping the fixing cover 16 and the bottle mouth of the can 100 sealed. This allows the subsequent filling operation to be carried out in a nearly completely sealed environment, greatly reducing the entry of air and the escape of carbon dioxide, thus ensuring the taste and quality of the beer.

[0034] After filling is completed, the filling gun 5 stops filling. The second drive assembly 14 drives the driven gear ring 15 to rotate in the opposite direction, releasing the torsional force on the filling sealing cover 1001. The first drive assembly 11 drives the driven gear disk 12 to rotate counterclockwise, and the arc groove 121 pushes the push rod 13 to move radially outward, relieving the squeezing force on the lower part of the filling sealing cover 1001. Subsequently, the lifting frame 4 is driven to rise as a whole through the first electric screw assembly 3. Under the action of the second return spring 19, the filling gun 5 first moves from the can... The filling gun 5 is pulled out from the bottle mouth of the beer barrel (can body 100). The fixing cover 16 and the adsorption assembly remain in their current positions. When the filling gun 5 passes upward through the adsorption assembly, the adsorption assembly wipes the filling nozzle of the filling gun 5 to remove the beer foam at the filling nozzle of the filling gun 5. As the lifting frame 4 continues to rise, the fixing cover 16 and the adsorption assembly also move upward away from the bottle mouth of the can body 100. Subsequently, the filling sealing plate 8, the filling sealing cover 1001 and other components completely leave the bottle mouth of the beer barrel (can body 100) and return to their original positions as the lifting frame 4 rises.
