Description

Technical Field

[0001] The present invention relates to the technical field of bottle cap cleaning, and particularly to a beverage filling production line with a cleaning function. Background Art

[0002] The beverage filling production line rapidly generates beverage filling through the coordinated action of mechanical transmission, automatic control and precision sensing technologies. Among them, a capping device is required during the production process. The capping device rotates and fixes the bottle cap on the bottle to ensure the sealing of the bottled liquid.

[0003] The patent with the publication number CN108423208A discloses a filling production line, including an alarm device, a sensing device, a first conveyor rack, a second conveyor rack, a third conveyor rack and a main control box. The first conveyor rack is parallelly connected to the second conveyor rack. The discharging end of the second conveyor rack is connected to a barrel holding device, and the barrel holding device is parallelly connected to the third conveyor rack. Along the output direction on the first conveyor rack, a main control box, a barrel dividing machine and a filling machine are sequentially arranged. The filling machine is arranged above the connection end of the first conveyor rack and the second conveyor rack. The above production line utilizes advanced weighing technology to smoothly push the barrel to the center of the weighing platform through a servo motor, automatically sense and fill. When the weight reaches the target set value, the automatic filling process is completed, and then the cap is buckled, rotated and palletized.

[0004] However, before capping, since the inside of the bottle cap adheres to sundries during the transfer and placement of the bottle cap, the existing filling production line cannot ensure the cleanliness of the inside of the bottle cap during capping installation, which easily causes the transfer of sundries into the liquid, affecting the sales of beverages. Therefore, it is necessary to clean the bottle cap before capping installation. Summary of the Invention

[0005] The purpose of the present invention is to solve the defect that the existing filling production line cannot ensure the cleanliness of the inside of the bottle cap during capping installation, which easily causes the transfer of sundries into the liquid, affecting the sales of beverages, and to propose a beverage filling production line with a cleaning function.

[0006] In order to achieve the above purpose, the present invention adopts the following technical scheme: A beverage filling production line with a cleaning function includes: a conveying table, a capping assembly, a mounting frame and a push cap assembly mounted on the mounting frame. A transfer frame assembly is arranged on the mounting frame. The transfer frame assembly includes a pushing tube, a cap placing tube and a connecting plate. The pushing tube is fixedly connected to the mounting frame. The connecting plate is fixedly connected to the upper end of the pushing tube. The cap placing tube is fixedly connected to the other end of the connecting plate; A driving component is arranged at the bottom of the cap placing tube, and a cleaning component is arranged at the upper end of the driving component. The cleaning component includes a conduit, a pushing tube, and a spraying end. The conduit is fixedly connected to the upper end of the driving component. The pushing tube is hermetically and slidably arranged at the upper end of the conduit. The spraying end is fixedly connected to the upper end of the pushing tube. The spraying end is disc-shaped, and a plurality of spraying valves are annularly arranged on the upper surface and the side of the spraying end. Two inner supporting components are symmetrically arranged on both sides of the spraying end, and the two inner supporting components are used to fix the bottle cap from the inside.

[0007] Preferably, the driving component includes a driving motor and a mounting rod. The mounting rod is fixedly connected to the bottom of the cap placing tube. The driving motor is fixedly installed on the mounting rod, and the output end is arranged upward. The output end of the driving motor is fixedly connected to the bottom end of the conduit.

[0008] Preferably, an impeller is arranged at the output end of the driving motor. The impeller is arranged at the bottom of the conduit and forms an air flow from top to bottom when rotating.

[0009] Preferably, the cleaning component further includes a material guiding ring and two material tubes. The material guiding ring is rotatably installed on the conduit. A plurality of openings are arranged on the side of the conduit, and the openings are located inside the material guiding ring. The two material tubes are symmetrically arranged on both sides of the material guiding ring and are respectively used to introduce cleaning liquid and hot air.

[0010] Preferably, the inner supporting component includes a telescopic tube and a supporting block. The telescopic tube is horizontally fixedly connected to the side of the spraying end, and the supporting block is fixedly connected to the end of the telescopic tube.

[0011] Preferably, the upper surface of the spraying end is frustum-shaped, and a contact block is arranged at the top. The contact block is made of an elastic material and is used to contact the top wall of the bottle cap.

[0012] Preferably, a plurality of card slots are arranged inside the opening at the upper end of the conduit. The bottom end of the pushing tube is funnel-shaped, and a plurality of card strips are arranged on the side. The card strips are clamped inside the card slots and are used for the conduit to drive the pushing tube to rotate.

[0013] Preferably, a limiting component is arranged on the side of the cap placing tube. The limiting component is used to limit the position of the bottle cap inside the moving cap placing tube. The limiting component includes two bottom strips, a limiting strip, three sleeves, and a hydraulic bottle. The three sleeves are fixedly connected to the side of the cap placing tube and are arranged in a triangle. The limiting strip is fixedly and hermetically slidably arranged inside the upper sleeve. The two bottom strips are symmetrically and hermetically slidably arranged inside the lower two sleeves. The hydraulic bottle is arranged among the three sleeves and is respectively communicated with the three sleeves through connecting pipes and is used to control the movement of the bottom strips and the limiting strip.

[0014] Preferably, one side of the two limiting strips close to each other is provided with an inclined edge in a shape of an inverted V. Two deflecting blocks are symmetrically arranged on the connecting plate, and the deflecting blocks are used for expanding the two limiting strips to both sides.

[0015] Preferably, two discharge strip openings are arranged at the bottom side of the limiting strip. Two connecting pipes are arranged on the sleeve located above. The two connecting pipes are respectively communicated with the two discharge strip openings and are used for discharging cleaning liquid and hot air.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. During cleaning, the driving assembly drives the cleaning assembly to rotate, and the cleaning liquid is sprayed out through the opened spraying valve, so as to clean the rotating bottle cap. After the cleaning liquid finishes cleaning, the driving assembly stops, and then hot air is introduced into the conduit, so that the spraying end ejects hot air to perform drying treatment on the inside of the bottle cap, thereby completing the rapid cleaning of the bottle cap. The disc-shaped spraying end can evenly spray the cleaning liquid and hot air. Through the dual cleaning of the cleaning liquid and hot air, while improving the cleaning efficiency, the cleaning effect is ensured; 2. Driven by the driving motor to rotate, during the rotation of the impeller, an air flow from top to bottom will be generated. During the cleaning of the bottle cap, first, high-pressure cleaning will be performed through the cleaning liquid, and then drying treatment will be performed through high-temperature hot air. In order to quickly transfer the discharged cleaning liquid and hot air, an air flow is generated by the impeller, so as to complete the directional transfer of the cleaning liquid and hot air, and ensure the dryness between the entire cap placing pipe and the bottle cap after cleaning; 3. The cleaning liquid and hot air are introduced into the telescopic pipe, so that the telescopic pipe expands. After the telescopic pipe expands and extends, the supporting block is driven to squeeze against the inner side of the bottle cap, thereby completing the fixation of the position of the bottle cap. At the same time, during the rotation of the cleaning assembly, the bottle cap is driven to rotate, improving the cleaning efficiency and cleaning effect; 4. The bottle cap placed on the upper side of the bottom strip will move along with the bottom strip towards the position of the pushing pipe. As the bottom strip moves, the elastic bottom strip is deflected by the deflecting block, causing the two bottom strips to deflect outwards, so that the distance between the two bottom strips increases. When the bottle cap is transferred to the upper side of the pushing pipe, the bottle cap is separated from the bottom strip, thereby reducing the position offset of the bottle cap during the transfer process and ensuring the horizontal dropping of the bottle cap; 5. During the transfer of the bottle cap, impurities may also adhere to the outer side of the bottle cap. By providing two discharge strip openings on the limiting strip, the outer surface of the bottle cap can be cleaned while the cleaning assembly cleans the inner side of the bottle cap, ensuring the overall cleanliness of the bottle cap.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Refer to Figures 1-8 , a beverage filling production line with a cleaning function, including: a conveying table 1, a capping assembly, a mounting rack 2, and a cap pushing assembly mounted on the mounting rack 2. A transfer rack assembly 3 is provided on the mounting rack 2. The transfer rack assembly 3 includes a pushing tube 31, a cap placing tube 32, and a connecting plate 33. The pushing tube 31 is fixedly connected to the mounting rack 2. The connecting plate 33 is fixedly connected to the upper end of the pushing tube 31. The cap placing tube 32 is fixedly connected to the other end of the connecting plate 33; A driving component 5 is arranged at the bottom of the cap placing pipe 32, and a cleaning component 4 is arranged at the upper end of the driving component 5. The cleaning component 4 includes a conduit 41, a pushing pipe 42 and a spraying end 43. The conduit 41 is fixedly connected to the upper end of the driving component 5. The pushing pipe 42 is hermetically and slidably arranged at the upper end of the conduit 41. The spraying end 43 is fixedly connected to the upper end of the pushing pipe 31. The spraying end 43 is disc-shaped, and a plurality of spraying valves are annularly arranged on the upper surface and the side of the spraying end 43. Two inner support components 6 are symmetrically arranged on both sides of the spraying end 43, and the two inner support components 6 are used to fix the bottle cap from the inside.

[0021] In the embodiment applying the above technical solution, after the bottle cap is transferred above the cleaning component 4 through the cap placing pipe 32, cleaning liquid is first introduced into the conduit 41. During the process of being introduced from below, the cleaning liquid will drive the pushing pipe 42 to move upward, so as to move the spraying end 43 to the inside of the bottle cap. At this time, the spraying valves are closed, and the cleaning liquid will be transferred to the inside of the inner support component 6. The inner support component 6 extends to fix the position of the bottle cap from the inside, avoiding the position deviation of the bottle cap during the cleaning process. During cleaning, the driving component 5 drives the cleaning component 4 to rotate, and the cleaning liquid is sprayed out through the opened spraying valves, so as to clean the rotating bottle cap. After the cleaning liquid finishes cleaning, the driving component 5 stops, and then hot air is introduced into the conduit 41 to make the spraying end 43 spray out hot air to dry the inside of the bottle cap, thus completing the rapid cleaning of the bottle cap. The disc-shaped spraying end 43 can uniformly spray out the cleaning liquid and hot air. Through the double cleaning of the cleaning liquid and hot air, while improving the cleaning efficiency, the cleaning effect is ensured.

[0022] The present invention can quickly complete the cleaning of the bottle cap, ensuring that there are no residues on the bottle cap during capping of the capping device and avoiding the transfer of impurities to the inside of the beverage.

[0023] The preferred technical solution in this embodiment: Refer to Figure 5 and Figure 6 The driving component 5 includes a driving motor 51 and a mounting rod 52. The mounting rod 52 is fixedly connected to the bottom of the cap placing pipe 32. The driving motor 51 is fixedly installed on the mounting rod 52, and the output end is arranged upward. The output end of the driving motor 51 is fixedly connected to the bottom end of the conduit 41. An impeller 8 is arranged at the output end of the driving motor 51. The impeller 8 is arranged at the bottom of the conduit 41 and forms an air flow from top to bottom when rotating.

[0024] During the cleaning process, the driving motor 51 drives the cleaning component 4 to rotate, so that the sprayed cleaning liquid can evenly impact the inner side of the bottle cap, ensuring the cleaning effect of the inside of the bottle cap.

[0025] At the same time, an impeller 8 is arranged at the driving end of the driving motor 51 and driven to rotate by the driving motor 51. During the rotation of the impeller 8, an air flow from top to bottom will be generated. During the cleaning process of the bottle cap, high-pressure cleaning will be carried out first with the cleaning liquid, and then drying treatment will be carried out with high-temperature hot air. In order to quickly transfer the exported cleaning liquid and hot air, an air flow is generated by the impeller 8, thereby completing the directional transfer of the cleaning liquid and hot air, and ensuring the dryness between the entire cap tube 32 and the bottle cap after cleaning.

[0026] At the same time, the driving motor 51 drives the entire cleaning component 4 to rotate, and the bottle cap fixedly connected by the inner support component 6 on the side of the cleaning component 4 will also rotate. After cleaning, the residual cleaning liquid on the bottle cap can be quickly thrown out, thereby ensuring the dryness of the bottle cap.

[0027] Refer to Figure 6 As shown, the cleaning component 4 further includes a material guiding ring 44 and two material tubes 45. The material guiding ring 44 is rotatably installed on the conduit 41. A plurality of openings are formed on the side of the conduit 41, and the openings are located inside the material guiding ring 44. The two material tubes 45 are symmetrically arranged on both sides of the material guiding ring 44 and are respectively used for introducing the cleaning liquid and hot air. Refer to Figure 6 As shown, the inner support component 6 includes a telescopic tube 61 and a support block 62. The telescopic tube 61 is horizontally fixedly connected to the side of the spraying end 43, and the support block 62 is fixedly connected to the end of the telescopic tube 61. The upper surface of the spraying end 43 is frustum-shaped, and a contact block is arranged at the top. The contact block is made of an elastic material and is used to contact the top wall of the bottle cap.

[0028] Since during the cleaning process, the export of the cleaning liquid and hot air will generate an impact force on the bottle cap, causing the displacement of the bottle cap position, thereby affecting the cleaning effect of the bottle cap. By arranging two inner support components 6 on the side of the spraying end 43, the fixing of the bottle cap is completed, avoiding the inclination and displacement of the bottle cap during the cleaning process, and ensuring the cleaning effect of the bottle cap.

[0029] During cleaning, when the cleaning liquid or hot air is introduced into the spraying end 43, the spraying valve closes, and the cleaning liquid and hot air are introduced into the telescopic tube 61, so that the telescopic tube 61 expands. After the telescopic tube 61 expands and extends, it drives the support block 62 to squeeze against the inner side of the bottle cap, thereby completing the fixing of the bottle cap position. At the same time, during the rotation of the cleaning component 4, the bottle cap is driven to rotate, improving the cleaning efficiency and cleaning effect.

[0030] By setting the upper surface of the ejection end 43 to a frustum shape, the cleaning liquid and steam dripping onto the ejection end 43 can slide down along the ejection end 43, thereby ensuring the dryness of the surface of the ejection end 43. At the same time, by the extrusion contact between the contact block and the inner side of the bottle cap, it is possible to avoid abrasion of the inner side of the bottle cap during the rotation of the bottle cap.

[0031] Refer to Figure 6 , a plurality of card slots 9 are provided inside the inner opening of the upper end of the conduit 41. The bottom end of the push tube 42 is set to a funnel shape, and a plurality of card strips 10 are provided on the side. The card strips 10 are clamped inside the card slots 9 for the conduit 41 to drive the push tube 42 to rotate.

[0032] Since the conduit 41 and the push tube 42 are slidably arranged, during the rotation of the conduit 41 by the driving motor 51, the push tube 42 cannot be driven to rotate, so that the fixed bottle cap cannot be rotated, affecting the overall cleaning.

[0033] When the cleaning liquid or hot air enters the conduit 41, it will push the push tube 42 at the funnel-shaped end to move upward. During the upward movement of the push tube 42, the card strips 10 provided on the side will be clamped inside the card slots 9 of the conduit 41, so that the sliding push tube 42 is clamped with the conduit 41, ensuring that the conduit 41 will drive the push tube 42 to rotate during rotation, realizing the subsequent driving of the bottle cap to rotate.

[0034] Refer to Figure 7 and Figure 8 , a limiting component 7 is provided on the side of the cap placing tube 32. The limiting component 7 is used to limit the position of the bottle cap inside the movable cap placing tube 32. The limiting component 7 includes two bottom strips 71, a limiting strip 72, three sleeves 73 and a hydraulic bottle 74. The three sleeves 73 are fixedly connected to the side of the cap placing tube 32 and are arranged in a triangle. The limiting strip 72 is fixedly and sealingly slidably arranged inside the upper sleeve 73. The two bottom strips 71 are symmetrically and sealingly slidably arranged inside the lower two sleeves 73. The hydraulic bottle 74 is arranged between the three sleeves 73 and is communicated with the three sleeves 73 through connecting pipes respectively, for controlling the movement of the bottom strips 71 and the limiting strip 72; One side of the two limiting strips 72 close to each other is set as an inclined edge in an eight-character shape. Two deflection blocks 11 are symmetrically arranged on the connecting plate 33. The deflection blocks 11 are used to expand the two limiting strips 72 to both sides.

[0035] Since during the cleaning of the bottle cap, the ejected cleaning liquid and hot air will both generate an upward impact force. In order to ensure the limitation of the position of the bottle cap, the bottom strips 71 and the limiting strip 72 are respectively arranged on the upper and lower sides of the bottle cap for limiting the bottle cap from the upper and lower sides.

[0036] Before the cleaning starts, by adjusting the hydraulic oil inside the hydraulic bottle 74, the limiting strip 72 is completely located inside the upper sleeve 73, so that the upper side of the cap placing tube 32 is not blocked, while the lower bottom strip 71 extends outwards. Since the distance between the two bottom strips 71 is smaller than the diameter of the bottle cap but larger than the diameter of the spraying end 43, the bottle cap to be cleaned can be placed above the bottom strip 71.

[0037] During the cleaning process, by adjusting the hydraulic oil inside the hydraulic bottle 74, the limiting strip 72 extends out and is restricted above the bottle cap. At the same time, the lower bottom strip 71 is retracted inwards to limit the bottle cap from above.

[0038] If the cleaned bottle cap is pushed into the pushing tube 31, it may tilt during the transfer process of the bottle cap, resulting in the bottle caps not being stacked horizontally, which affects the subsequent pushing of the bottle caps. To prevent the bottle cap from tilting during the transfer process, after the cleaning is completed, the limiting strip 72 is retracted again, while the bottom strip 71 extends outwards. The bottle cap placed on the upper side of the bottom strip 71 will move towards the position of the pushing tube 31 along with the bottom strip 71. As the bottom strip 71 moves, the elastic bottom strip 71 is deflected by the deflection block 11, causing the two bottom strips 71 to deflect outwards, thereby increasing the distance between the two bottom strips 71. When the bottle cap is transferred to the upper side of the pushing tube 42, the bottle cap is separated from the bottom strip 71, thus reducing the position offset of the bottle cap during the transfer process and ensuring the horizontal dropping of the bottle cap.

[0039] Refer to Figure 8 , two discharge strip openings 12 are provided on the bottom side of the limiting strip 72, and two connecting pipes are provided on the upper sleeve 73. The two connecting pipes are respectively communicated with the two discharge strip openings 12 for discharging cleaning liquid and hot air.

[0040] During the transfer process of the bottle cap, impurities may also adhere to the outer side of the bottle cap. By providing two discharge strip openings 12 on the limiting strip 72, the outer surface of the bottle cap can be cleaned while the cleaning assembly 4 cleans the inner side of the bottle cap, ensuring the overall cleanliness of the bottle cap.
