Description

Technical Field

[0001] The utility model relates to the technical field of liquor production, in particular to automatic bottle cap tightening equipment for a liquor filling production line. Background Art

[0002] Liquor is a unique liquor in my country with a large demand. In order to meet the large market demand, the baijiu filling production needs to be completed automatically. There are many steps in the baijiu filling production, among which the bottle cap sealing requires two steps: first, put the bottle cap on the bottle mouth, and then screw the cap to seal;

[0003] According to the public number: CN218025363U, an automatic screwing device for bottle caps of liquor filling production line is disclosed. This technology discloses "an automatic screwing device for bottle caps of liquor filling production line, a material guide component has a non-closed annular path for guiding liquor bottles; a housing is placed above the material guide component, and a driving component is arranged in the housing; a plurality of rotating racks are provided, and the rotating racks are distributed in an annular manner around the housing, and the rotating racks slide vertically elastically with the material guide component through springs, and the rotating racks are connected to the driving component; a pressure plate is fixed on the housing. The bottom surface of the pressing plate inside the shell gradually decreases in height from the two ends to the middle of the non-closed annular path, and the top of the rotating frame contacts the bottom surface of the pressing plate. The technical solutions have the advantages of "using the guide channel to continuously push the wine bottles to conduct in a circular manner around the turntable, and the rotating frame and the bottle caps are aligned during the circular conduction of the wine bottles. The rotating frame is driven to rotate by the transmission component during the circular conduction, and the contact of the pressing plate causes the rotating frame to gradually move downward to tighten the aligned bottle caps. The whole process does not require pauses, thereby achieving efficient assembly line-type cap tightening";

[0004] Although the above solution realizes the function of automatic tightening of bottle caps without pause on the production line and demonstrates high efficiency, there is a key problem in product quality assurance: precise control of the tightening force of the bottle cap. Tightening force is an important indicator for measuring product quality. If the tightening force is too large, it is very easy to cause the bottle cap to deform or even damage, affecting the appearance and practicality of the product; conversely, if the tightening force is too small, it may cause the bottle cap to loosen and lack of sealing, thereby affecting the shelf life and safety of the product. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an automatic bottle cap tightening device for a liquor filling production line, which has the characteristics of automatically loading the bottle cap to the bottle mouth and preventing the bottle cap from loosening during the tightening process to avoid affecting the accuracy.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automatic bottle cap tightening device for a liquor filling production line, comprising a machine base, a tightening mechanism provided on the machine base and used to tighten the bottle cap, the tightening mechanism comprising:

[0007] The main assembly includes a lifting column fixed to the top of the machine base and a frame fixed to the upper end of the lifting column;

[0014] Beneficial effects

[0015] The utility model provides an automatic bottle cap tightening device for a liquor filling production line. Compared with the existing technology, it has the following advantages:

[0016] (1) When the turntable rotates and drives the bottle capped with the bottle to move to the bottom of the actuator, the lifting column drives the frame to drive the actuator to press down the bottle cap on the bottle. When the guide head contacts the bottle cap and is squeezed, it moves upward. The guide head drives the clamp inward through the protrusion, thereby clamping and fixing the bottle cap to avoid loosening during the subsequent tightening process, which affects the tightening accuracy.

[0017] (2) The bottle cap inside is transported to the cap hanging track through the vibrating plate. When the bottle cap slides to the lowest end inside the cap hanging track, it is limited by the cap pressing plate and stuck between the spring pieces on both sides. At this time, the bottle cap is in a semi-inclined state, and the opening of the bottle cap faces the direction of the wine bottle. When the turntable rotates and drives the wine bottle to move below the bottle cap, the mouth of the bottle contacts one end of the bottle cap opening, and the wine bottle continues to move through the cap hanging track, so that the wine bottle drives the bottle cap to detach from the lower end of the inner part of the cap hanging track, and the bottle cap is covered on the bottle mouth of the wine bottle, realizing automatic loading of the bottle cap.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The utility model provides a technical solution for an automatic bottle cap tightening device for a liquor filling production line: an automatic bottle cap tightening device for a liquor filling production line, comprising a machine base 1, a tightening mechanism 2 is provided on the machine base 1 and is used to tighten the bottle cap, the tightening mechanism 2 comprises:

[0027] The main assembly 21 includes a lifting column 211 fixed to the top of the base 1 and a frame 212 fixed to the upper end of the lifting column 211;

[0028] The actuator 22 includes an upper cylinder 221 rotatably mounted on the frame 212, a lower cylinder 222 slidably mounted penetrating through the lower end of the upper cylinder 221, an axle seat 223 fixed at the lower end of the lower cylinder 222, three circumferentially distributed clamps 224 hinged at the lower end of the axle seat 223, a protrusion 225 fixed to the inner wall of the upper end of the clamp 224, a guide head 226 slidably mounted penetrating through the lower end of the axle seat 223, and the protrusion 225 is located inside the outer wall of the guide head 226.

[0029] In this embodiment, when the turntable 7 rotates to drive the wine bottle with the bottle cap to move to the bottom of the actuator 22, the lifting column 211 drives the frame 212 to drive the actuator 22 to press down the bottle cap on the wine bottle. When the guide head 226 contacts the bottle cap and moves upward after being squeezed, the guide head 226 drives the clamp 224 to gather inward through the protrusion 225, thereby clamping and fixing the bottle cap to avoid loosening during the subsequent tightening process, which leads to precision control of tightening.

[0030] Specifically, the actuator 22 further includes a return spring 227 installed inside the lower cylinder 222 , and the return spring 227 is sleeved and installed on the outer wall of the upper end of the guide head 226 .

[0031] In this embodiment, when the main body component 21 drives the actuator component 22 to rise, the guide head 226 is separated from the bottle cap and the squeezing is released, so that the rebound pressure of the return spring 227 pushes the guide head 226 to move downward, and the guide head 226 drives the clamp 224 to open outward through the protrusion 225, thereby releasing the fixation of the bottle cap.

[0032] Specifically, the actuator 22 further includes a buffer spring 228 sleeved and mounted on the outer wall of the lower end of the upper cylinder 221 , and the buffer spring 228 is located between the upper cylinder 221 and the lower cylinder 222 .

[0033] In this embodiment, the execution component 22 can be buffered by the buffer spring 228 when it contacts the bottle cap on the wine bottle below.

[0034] Specifically, the main body component 21 also includes a driven pulley 213 fixed to the outer wall of the upper end of the upper cylinder 221, a driving pulley 214 rotatably installed inside the frame 212, a belt 215 installed between the driving pulley 214 and the driven pulley 213, and a motor 216 installed at the bottom of the frame 212 and used to drive the driving pulley 214.

[0035] In this embodiment, the output end of the motor 216 drives the active pulley 214 to cooperate with the belt 215 to drive the driven pulley 213 to rotate, and the driven pulley 213 automatically tightens the bottle cap on the wine bottle through the actuator 22.

[0036] Specifically, a vibration plate 3 is fixed to the top rear end of the machine base 1, a cover hanging track 4 is fixed to the discharge port of the vibration plate 3, a cover pressing piece 5 is fixed to the bottom of the lower end of the cover hanging track 4, and spring pieces 6 are fixed on both sides of the lower end of the cover hanging track 4.

[0037] In this embodiment, the bottle cap inside is transported to the cap hanging track 4 by the vibrating disk 3. When the bottle cap slides to the lowermost end inside the cap hanging track 4, it is limited by the pressing piece 5 and stuck between the spring pieces 6 on both sides. At this time, the bottle cap is in a semi-inclined state, and the opening of the bottle cap is facing the direction of the wine bottle. When the turntable 7 rotates to drive the wine bottle to move below the bottle cap, the bottle mouth of the wine bottle contacts one end of the bottle cap opening, and the bottle is continued to be driven to move by the cap hanging track 4, so that the wine bottle drives the bottle cap to detach from the lower end of the inner part of the cap hanging track 4, and the bottle cap is covered on the bottle mouth of the wine bottle.

[0038] Specifically, a turntable 7 is installed on the top of the machine base 1, and a feed conveyor belt 8 and a discharge conveyor belt 9 are fixed to the front and rear ends of the top of the machine base 1 respectively. A cylinder 10 is installed on the outer wall of the discharge conveyor belt 9, and a bottle pulling plate 11 is fixed to the output end of the cylinder 10.

[0039] In this embodiment, after the bottle cap is screwed onto the wine bottle, the turntable 7 continues to rotate to drive the wine bottle with the bottle cap to move to one side of the discharge conveyor belt 9, and then the output end of the cylinder 10 contracts to drive the bottle pulling plate 11 to pull the wine bottle with the bottle cap out of the turntable 7, so that it enters the discharge conveyor belt 9 and is sent to the next process.

[0040] The working principle and use process of the utility model are as follows: first, the wine bottles without bottle caps are fed to the turntable 7 by the feeding conveyor belt 8, and at the same time, the bottle caps inside are fed to the cap hanging track 4 by the vibrating plate 3. When the bottle caps slide to the lowermost end inside the cap hanging track 4, they are limited by the cap pressing piece 5 and stuck between the spring pieces 6 on both sides. At this time, the bottle caps are in a semi-inclined state, and the opening of the bottle caps faces the direction of the wine bottle. When the turntable 7 rotates to drive the wine bottle to move below the bottle caps, the mouth of the bottle contacts one end of the opening of the bottle cap, and the bottle is continued to be driven to move by the cap hanging track 4, so that the bottle drives the bottle caps to detach from the lower end inside the cap hanging track 4, and the bottle caps are covered on the bottle mouth of the wine bottle;

[0041] Then, when the turntable 7 rotates and drives the bottle capped to move to the bottom of the actuator 22, the lifting column 211 drives the frame 212 to drive the actuator 22 to press the bottle cap on the bottle. When the guide head 226 contacts the bottle cap and is squeezed, it moves upward. The guide head 226 drives the clamping head 224 to gather inward through the protrusion 225, thereby clamping and fixing the bottle cap. Then, the output end of the motor 216 drives the active pulley 214 to cooperate with the belt 215 to drive the driven pulley 213 to rotate. The driven pulley 213 automatically tightens the bottle cap on the bottle through the actuator 22.

[0042] Finally, the main body assembly 21 drives the actuator assembly 22 to rise. Since the guide head 226 is separated from the bottle cap and the extrusion is released, the guide head 226 is pushed downward by the rebound pressure of the return spring 227. The guide head 226 drives the clamp 224 to open outward through the protrusion 225, releasing the fixation of the bottle cap; then the turntable 7 continues to rotate to drive the wine bottle with the bottle cap to move to one side of the discharge conveyor belt 9, and then the output end of the cylinder 10 contracts to drive the bottle pulling plate 11 to pull the wine bottle with the bottle cap from the turntable 7, so that it enters the discharge conveyor belt 9 and is sent to the next process.
