Description

Technical Field

[0001] The present invention relates to the technical field of crack detection of wine bottles, and particularly to a crack detection device for glass wine bottles. Background Art

[0002] Glass products are prone to cracks due to production processes and storage environments. In the wine production industry, it is necessary to detect whether there are cracks in glass wine bottles before canning. Generally, the glass wine bottles before canning have undergone surface beautification treatments such as spraying glaze and labeling, and cracks cannot be directly observed by the naked eye. In modern industrial production, an airtight detector is used to seal and blow air into the glass wine bottles, and the air pressure is set within an appropriate range according to the thickness and shape of the glass wine bottles. The glass wine bottles with cracks will be blown up, while the glass is intact.

[0003] Chinese Patent Publication No. CN109029875B discloses a crack detection device for glass wine bottles, which includes a first conveyor line and a second conveyor line arranged at intervals. A spiral indexing mechanism is arranged on one side of the first conveyor line, and a rotary conveyor mechanism is offset between the first conveyor line and the second conveyor line. The spiral indexing mechanism is used to adjust the movement rhythm of the wine bottles along the first conveyor line to be consistent with the rhythm of the rotary conveyor mechanism. The rotary conveyor mechanism includes a frame and a star wheel. A support plate is fixed on the frame. The support plate, the star wheel, and the guard plate are coaxially arranged. The star wheel is located above the support plate. The star wheel is evenly provided with a plurality of conveying units along the circumferential direction. A second rotary motor drives the star wheel to rotate continuously. The glass wine bottles enter the support plate from the first conveyor line, and the star wheel drives the glass wine bottles to rotate onto the second conveyor line. A rotary detection mechanism is arranged directly above the rotary conveyor mechanism, and the rotary detection mechanism detects cracks in the glass wine bottles. An ejection mechanism is arranged in the middle of the second conveyor line, and the ejection mechanism ejects the glass wine bottles with cracks.

[0004] Chinese Patent Publication No. CN109060276B discloses a crack detection device for glass wine bottles, which includes a first conveyor line and a second conveyor line arranged side by side. A frame is located between the first conveyor line and the second conveyor line. A plurality of crack detection units with the same structure are arranged on the frame at the same interval along the movement direction of the first conveyor line. In the crack detection unit, a first pushing mechanism and a second pushing mechanism are both installed on the frame. A middle channel is perpendicular to the first conveyor line and is located between the first conveyor line and the second conveyor line. The first pushing mechanism and the second pushing mechanism are arranged along the middle channel and are located above the middle conveying channel. The middle channel includes a bottom plate, and a temporary storage position and a leak are arranged on the bottom plate. The temporary storage position is close to the first conveyor line, and the leak is close to the second conveyor line. A detection mechanism is used to detect the glass wine bottles, and the leak is used to let the glass wine bottles with cracks fall through. This device can automatically detect whether there are cracks in the glass wine bottles.

[0005] However, detecting whether there are cracks in a wine bottle by blowing it up has certain risks. In modern industrial production, there is another detection method. By connecting a blowing structure to the bottle mouth of the wine bottle, placing the wine bottle to be detected in a liquid, and blowing air into the wine bottle to increase the air pressure inside the bottle, whether there are bubbles generated in the liquid is used to determine whether the wine bottle is cracked. However, the detection devices in the prior art are inconvenient to completely block the bottle mouths of different calibers, so it is inconvenient to immerse the bottle mouths in the liquid, resulting in the wine bottles being located at a relatively shallow depth inside the liquid, the bubble floating distance being short, and it being easy to miss observing the generated bubbles. Therefore, a crack detection device for glass wine bottles is proposed. Summary of the Invention

[0006] In order to block the bottle mouths of wine bottles with different calibers and then extend the wine bottles deep into the liquid to facilitate observing the generated bubbles, the present invention provides a crack detection device for glass wine bottles.

[0007] A crack detection device for glass wine bottles provided by the present invention adopts the following technical solution: It includes a transparent water tank and a fixing frame. The fixing frame is located above the transparent water tank, and the two ends of the fixing frame are detachably connected to the left and right side surfaces of the transparent water tank respectively. A fixing disk is fixedly inserted in the part of the fixing frame located above the transparent water tank. A sandwich cover pipe is arranged below the fixing disk. The outer ring surface of the sandwich cover pipe is elastically connected to the bottom surface of the fixing disk. The axis of the sandwich cover pipe is a through-hole structure. A clamping cavity layer is formed between the outer surface of the sandwich cover pipe and the through-hole structure of the sandwich cover pipe. An inner column rotates through the upper surface of the fixing disk, and the lower end of the inner column is slidably inserted into the through-hole structure inside the sandwich cover pipe. An air supply structure slidably penetrates through the upper surface of the sandwich cover pipe, and the lower end of the air supply structure is located inside the clamping cavity layer. The fixing disk is fixedly sleeved on the lower end of the air supply structure. A notch is formed on the outer ring surface at the lower end of the sandwich cover pipe, and a sealing elastic air bag is fixedly inserted inside the notch. An air pressure valve A is fixedly penetrated through the bottom surface of the sandwich cover pipe, and the upper end of the air pressure valve A is located inside the clamping cavity layer.

[0008] Optionally, the air supply structure includes a ventilation ring and a power inflation pump. A plurality of single-head vertical pipes are fixedly communicated with the bottom surface of the ventilation ring. The fixing disk is fixedly sleeved on the outer surface of the single-head vertical pipes. The sandwich cover pipe is slidably sleeved on the outer surface of the single-head vertical pipes. The lower ends of the single-head vertical pipes are located inside the sandwich cover pipe. The upper end of the ventilation ring is fixedly sleeved on the air outlet end of the power inflation pump.

[0009] Optionally, the upper end of the single-head vertical pipe is in an open shape, the lower end of the single-head vertical pipe is in a closed shape, an air outlet hole is formed at one end of the lower end of the single-head vertical pipe close to the axis of the sandwich cover pipe, a gas blocking plate is in contact and sealed on one side of the air outlet hole close to the axis of the sandwich cover pipe, the gas blocking plate is fixed to the inner wall of the clamping cavity layer, and an air pressure valve B is installed on the upper surface of the ventilation ring.

[0010] Optionally, a bracket is provided below the sandwich cover tube. A circular ring is fixed to the upper end of the bracket. The circular ring is slidably sleeved on the outer surface of the sandwich cover tube. The bottom surface of the circular ring is elastically connected to the outer surface of the sandwich cover tube. The lower end of the bracket is arranged in a disc-shaped structure coaxial with the sandwich cover tube.

[0011] Optionally, a plurality of through grooves are formed in the inner wall of the outer ring of the sandwich cavity layer. The plurality of through grooves are evenly distributed in three columns inside the sandwich cavity layer. A plurality of air pressure baffles are slidably inserted into the through grooves. The air pressure baffles are elastically connected to the inner walls of the through grooves.

[0012] Optionally, a plurality of annular grooves are formed on the outer ring surface of the sealing elastic airbag. A plurality of suction cups are fixed inside each annular groove.

[0013] Optionally, a plurality of evenly distributed air release groove holes A are formed in the bottom surface of the inner column. The outer diameter of the inner column at the joint with the fixed disk is smaller than the outer diameter of the rest of the inner column. Air release groove holes B are formed on the upper surface of the inner column and above each air release groove hole A. A plurality of evenly distributed air vent groove holes are formed on the upper surface of the fixed disk.

[0014] Optionally, the number of the air vent groove holes is equal to the number of the air release groove holes A. The distance between the air vent groove holes and the axis of the inner column is equal to the distance between the air release groove holes A and the axis of the inner column. The air release groove holes A are coaxially arranged with the air release groove holes B located below. The sizes of the air release groove holes A, the air release groove holes B and the air vent groove holes are adapted to each other. The width between every two adjacent air vent groove holes is greater than the width of the air vent groove holes.

[0015] Optionally, the inner column is located between a plurality of single-headed vertical tubes. The plurality of single-headed vertical tubes are evenly distributed in a circumferential array around the axis of the sandwich cover tube.

[0016] In summary, the present invention includes the following beneficial technical effects:

[0017] 1. By providing the sandwich cover tube, the sealing elastic airbag and the inner column, the sealing elastic airbag is located inside the wine bottle mouth. The sandwich cavity layer is inflated. The sealing elastic airbag gradually expands to seal the wine bottle mouth as the air pressure inside the sandwich cavity layer increases. Then, when the sandwich cavity layer is continuously inflated, the air pressure valve A opens when the air pressure in the sandwich cavity layer reaches a certain level, so that the gas in the sandwich cavity layer can enter the wine bottle interior through the air pressure valve A. As the air pressure inside the wine bottle increases, the sandwich cover tube is pushed to move downward relative to the inner column, and the bottle is pushed into the liquid deep inside the transparent water tank, and it can be observed whether bubbles are generated as the air pressure inside the bottle increases, and the detection is safe.

[0018] 2. The present invention sets up a bracket, a circular ring, an air-blocking plate and air outlet holes. The wine bottle is placed above the lower disc structure of the bracket, and at the same time, the sealing elastic airbag is placed at the bottle mouth of the wine bottle. The gravity of the wine bottle drives the sandwich cover tube to move downward relative to the fixed disc by a certain distance, driving the air-blocking plate to be misaligned with the air outlet holes, so that the single-head vertical tube can inflate the clamping cavity layer, effectively preventing air from being inflated into the clamping cavity layer before the sealing elastic airbag is inserted into the wine bottle. After the sealing elastic airbag expands, it is inconvenient to insert it into the wine bottle.

[0019] 3. The present invention sets up a through groove and a pneumatic baffle. When the air pressure in the clamping cavity layer increases, the pneumatic baffle is gradually pushed to extend in the through groove, and the extended pneumatic baffle blocks the circular ring, effectively preventing the sealing elastic airbag from separating from the wine bottle after the air pressure in the wine bottle increases.

[0020] 4. The present invention sets up a deflation groove hole A, a deflation groove hole B and a ventilation groove hole. Before detection, the inner column is rotated to misalign the deflation groove hole A with the ventilation groove hole, and the air pressure below the inner column can increase. After the detection is completed, the inner column is rotated to drive the ventilation groove hole to communicate with the deflation groove hole A and the deflation groove hole B, and the air pressure below the inner column and in the wine bottle is relieved. The wine bottle moves downward under the action of the elastic connection between the sandwich cover tube and the fixed disc to separate from the liquid, and then the power inflation pump is stopped to separate the wine bottle from the sealing elastic airbag, effectively preventing the detection liquid from entering the wine bottle and causing pollution to the inside of the wine bottle.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0034] The following will be further described in detail with reference to the attached Figures 1-9 to further illustrate the present invention.

[0035] The embodiments of the present invention disclose a crack detection device for glass wine bottles. As Figures 1-9As shown, it includes a transparent water tank 1 and a fixing frame 2. The fixing frame 2 is located above the transparent water tank 1. The transparent water tank 1 is made of transparent material, which is convenient for observing the bubbles generated below the liquid level. The two ends of the fixing frame 2 are detachably connected to the left and right sides of the transparent water tank 1 respectively. A fixing plate 3 is fixedly inserted into the part of the fixing frame 2 located above the transparent water tank 1. A sandwich cover pipe 4 is arranged below the fixing plate 3. The outer ring surface of the sandwich cover pipe 4 is elastically connected to the bottom surface of the fixing plate 3. The axis of the sandwich cover pipe 4 is a through-hole structure. A sandwich cavity layer 5 is formed between the outer surface of the sandwich cover pipe 4 and the through-hole structure of the sandwich cover pipe 4. The fixing frame 2, the fixing plate 3 and the sandwich cover pipe 4 can be increased according to the number of detections, and multiple wine bottles can be detected simultaneously.

[0036] A bracket 10 is arranged below the sandwich cover pipe 4. A ring 11 is fixed at the upper end of the bracket 10. The ring 11 is slidably sleeved on the outer surface of the sandwich cover pipe 4. The bottom surface of the ring 11 is elastically connected to the outer surface of the sandwich cover pipe 4. The lower end of the bracket 10 is set as a disc-shaped structure coaxial with the sandwich cover pipe 4.

[0037] A plurality of through slots 12 are formed in the outer ring inner wall of the sandwich cavity layer 5. The plurality of through slots 12 are evenly distributed in three columns inside the sandwich cavity layer 5. A plurality of air pressure baffles 13 are slidably inserted into the through slots 12. The air pressure baffles 13 are elastically connected to the inner walls of the through slots 12. When detecting the wine bottle, the bottom of the wine bottle is placed above the disc-shaped structure of the bracket 10. When the air pressure in the sandwich cavity layer 5 increases, the air pressure baffles 13 are gradually pushed to extend out in the through slots 12, and the extended air pressure baffles 13 block the ring 11.

[0038] An inner column 17 rotatably penetrates through the upper surface of the fixing plate 3. The lower end of the inner column 17 is slidably inserted into the through-hole structure inside the sandwich cover pipe 4.

[0039] A plurality of uniformly distributed air leakage slot holes A16 are formed in the bottom surface of the inner column 17. The outer diameter of the inner column 17 at the joint with the fixing plate 3 is smaller than the outer diameter of the rest of the inner column 17. Air leakage slot holes B18 are formed on the upper surface of the inner column 17 and above each air leakage slot hole A16. A plurality of uniformly distributed ventilation slot holes 19 are formed on the upper surface of the fixing plate 3.

[0040] The number of ventilation slots 19 is equal to the number of air release slots A16. The distance between the ventilation slots 19 and the axis of the inner column 17 is equal to the distance between the air release slots A16 and the axis of the inner column 17. The air release slots A16 are coaxially arranged with the air release slots B18 located below. The sizes of the air release slots A16, the air release slots B18, and the ventilation slots 19 are adapted to each other. The width between every two adjacent ventilation slots 19 is greater than the width of the ventilation slots 19, ensuring that the air release slots A16 can be completely misaligned with the ventilation slots 19. Before detection, rotate the inner column 17 to misalign the air release slots A16 with the ventilation slots 19, so that the air pressure below the inner column 17 can increase. After detection is completed, rotate the inner column 17 to drive the ventilation slots 19 to communicate with the air release slots A16 and the air release slots B18, and relieve the air pressure below the inner column 17 and inside the wine bottle.

[0041] The upper surface of the sandwich cover tube 4 is slidably penetrated by a gas supply structure 6. The lower end of the gas supply structure 6 is located inside the sandwich cavity layer 5. The fixed disk 3 is fixedly sleeved on the lower end of the gas supply structure 6.

[0042] The gas supply structure 6 includes a ventilation ring 61 and a power inflation pump 62. A plurality of single-headed vertical tubes 63 are fixedly communicated with the bottom surface of the ventilation ring 61. The fixed disk 3 is fixedly sleeved on the outer surface of the single-headed vertical tubes 63. The sandwich cover tube 4 is slidably sleeved on the outer surface of the single-headed vertical tubes 63. The lower ends of the single-headed vertical tubes 63 are located inside the sandwich cover tube 4. The upper end of the ventilation ring 61 is fixedly sleeved on the air outlet end of the power inflation pump 62.

[0043] A notch 8 is formed in the outer ring surface of the lower end of the sandwich cover tube 4. A plugging elastic airbag 7 is fixedly inserted into the notch 8. The material of the plugging elastic airbag 7 is such that it can elastically expand after inflation. A plurality of annular grooves 14 are formed in the outer ring surface of the plugging elastic airbag 7. A plurality of suction cups 15 are fixed in each annular groove 14. When the plugging elastic airbag 7 expands and contacts the inner wall of the wine bottle mouth, it drives the suction cups 15 to contact the wine bottle, effectively preventing the plugging elastic airbag 7 from moving up and down relative to the wine bottle.

[0044] An air pressure valve A9 is fixedly penetrated through the bottom surface of the sandwich cover tube 4. The upper end of the air pressure valve A9 is located inside the sandwich cavity layer 5.

[0045] The upper end of the single-headed vertical pipe 63 is open, and the lower end of the single-headed vertical pipe 63 is closed. An air outlet hole 631 is opened at one end of the lower end of the single-headed vertical pipe 63 close to the axis of the sandwich cover pipe 4. A gas blocking plate 632 is in contact and sealed on the side of the air outlet hole 631 close to the axis of the sandwich cover pipe 4. When no wine bottle is placed on the bracket 10, the gas blocking plate 632 blocks the air outlet hole 631 under the elastic connection of the sandwich cover pipe 4 and the fixed plate 3, effectively preventing air from being inflated into the sandwich cavity layer 5 before the plugging elastic airbag 7 is inserted into the wine bottle. After the wine bottle is placed above the lower disc structure of the bracket 10, the gravity of the wine bottle drives the sandwich cover pipe 4 to move downward relative to the fixed plate 3 by a certain distance, causing the gas blocking plate 632 to be misaligned with the air outlet hole 631. The power air pump 62 can inflate the sandwich cavity layer 5 through the single-headed vertical pipe 63 and the air outlet hole 631.

[0046] The gas blocking plate 632 is fixed to the inner wall of the sandwich cavity layer 5. A pressure valve B633 is installed on the upper surface of the ventilation ring 61. The inner column 17 is located between multiple single-headed vertical pipes 63. The multiple single-headed vertical pipes 63 are evenly distributed in a circumferential array around the axis of the sandwich cover pipe 4. The plugging elastic airbag 7 gradually expands and contacts the inner wall of the wine bottle mouth as the internal pressure of the sandwich cavity layer 5 increases. The expanded plugging elastic airbag 7 seals the wine bottle mouth. At this time, the air pressure in the sandwich cavity layer 5 cannot open the pressure valve A9. After the air pressure in the sandwich cavity layer 5 continues to increase, the air pressure pushes the pressure valve A9 to open, allowing gas to enter below the inner column 17 and the inside of the wine bottle. Then, when the air pressure in the wine bottle and below the inner column 17 is too high, the air pressure in the ventilation ring 61 increases synchronously, and the air pressure can push the pressure valve B633 to open for pressure relief of the internal air pressure. The pressure opening ranges of the pressure valve A9 and the pressure valve B633 and the elasticity of the elastic connection between the sandwich cover pipe 4 and the fixed plate 3 meet the structural operating conditions. The valve body of the pressure valve can be connected at both ends after being subjected to a certain pressure at one end.

[0047] The working principle is as follows: Place the wine bottle above the lower disc structure of the bracket 10, and at the same time place the sealing elastic airbag 7 at the bottle mouth of the wine bottle. The gravity of the wine bottle drives the sandwich cover tube 4 to move downward relative to the fixed disc 3 by a certain distance, causing the air blocking plate 632 to be misaligned with the air outlet hole 631. The power air pump 62 inflates the sandwich cavity layer 5 through the single-head vertical tube 63 and the air outlet hole 631. The sealing elastic airbag 7 gradually expands and contacts the inner wall of the bottle mouth of the wine bottle as the air pressure inside the sandwich cavity layer 5 increases. The expanded sealing elastic airbag 7 seals the wine bottle mouth. At the same time, when the air pressure in the sandwich cavity layer 5 increases, it gradually pushes the air pressure baffle 13 to extend in the through groove 12. The extended air pressure baffle 13 blocks the ring 11, effectively preventing the sealing elastic airbag 7 from detaching from the wine bottle after the air pressure in the wine bottle increases. Then, when continuing to inflate the sandwich cavity layer 5, the air pressure in the sandwich cavity layer 5 continues to increase. After the air pressure in the sandwich cavity layer 5 reaches a certain level, the air pressure valve A9 opens, allowing the gas in the sandwich cavity layer 5 to enter the wine bottle through the air pressure valve A9. As the air pressure inside the wine bottle increases, it pushes the sandwich cover tube 4 to move downward relative to the inner column 17, pushing the bottle deep into the liquid in the transparent water tank 1, and it can be observed whether bubbles are generated after the air pressure inside the bottle increases.

[0048] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
