Description

Technical Field

[0001] The invention belongs to the technical field of glass bottle production equipment, and specifically refers to a cold end spraying device for glass bottles. Background Art

[0002] By annealing the glass bottle, the thermal stress in the glass can be eliminated or reduced, thereby increasing the toughness and heat resistance of the glass bottle and improving its strength. The annealing of the glass bottle is divided into preheating stage, heating stage, insulation stage and cooling stage. The cold end spraying device is set in the cooling stage of the glass bottle annealing. Specifically, it is a device that sprays the cold end coating on the surface of the glass bottle container in a mist form when the glass bottle container is out of the annealing furnace. This technology can increase the strength, surface gloss, lubricity and friction resistance of the glass bottle container, so that it can effectively prevent surface scratches during subsequent operation and operation.

[0003] At present, the nozzle of the cold-end spraying device for glass bottles is arranged above the conveyor line, and the glass bottles are sprayed from top to bottom. During the production process, the glass bottles are usually placed on the conveyor line with their openings facing upwards, which causes the cold-end spray to enter the interior of the glass bottles during the spraying process, causing internal contamination of the glass bottles and increasing the complexity of the subsequent glass bottle cleaning process. In order to prevent the cold end spray from entering the inside of the glass bottle, the nozzle needs to be lowered below the mouth of the glass bottle. In actual use, glass bottles of various specifications will be annealed in one annealing furnace at the same time, which requires the nozzle to be lowered below the shortest mouth of the bottle, resulting in unsprayed areas on glass bottles with higher mouths, and the top-down spraying method cannot spray the bottom of the glass bottle. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a cold end spraying device for glass bottles, which at least partially solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a cold end spraying device for glass bottles, comprising: A conveyor belt, wherein a negative pressure component is provided above the conveyor belt and is arranged perpendicular to the conveying direction of the conveyor belt, and is used to extract air above the conveyor belt to form a negative pressure above the conveyor belt; An atomizing assembly is provided on the inner side of the conveyor belt and arranged perpendicular to the conveying direction of the conveyor belt. The atomizing assembly includes a plurality of atomizing heads, and the atomizing heads face upward. The atomizing assembly is located directly below the negative pressure assembly, so that an atomized liquid channel flowing from bottom to top is formed between the atomizing assembly and the negative pressure assembly; A driving component is provided on one side of the conveyor belt, one end of the atomizing assembly is connected to the output end of the driving component, and the driving component is configured to drive the atomizing assembly to swing back and forth so that the output direction of the atomizing assembly evenly sweeps the area to be sprayed of the glass bottle.

[0006] Furthermore, the negative pressure component includes a plurality of wind collecting hoods distributed perpendicular to the conveying direction of the conveyor belt, the wind collecting hood is provided with an enlarged end and a narrowed end, the enlarged end of the wind collecting hood faces downward, the narrowed end of the wind collecting hood is provided with an induced draft fan, and the input end of the induced draft fan is connected to the narrowed end of the wind collecting hood through a pipe.

[0007] Furthermore, the negative pressure component also includes an exhaust duct, and the output ends of the multiple induced draft fans are all connected to the exhaust duct.

[0008] Furthermore, the atomization assembly includes a liquid supply pipe arranged perpendicular to the conveying direction of the conveyor belt, the atomization heads are distributed on both sides of the liquid supply pipe, and multiple atomization heads are evenly distributed along the length direction of the liquid supply pipe, one end of the liquid supply pipe is connected to an external liquid supply device, and the other end of the liquid supply pipe is connected to the output end of the driving component.

[0009] Furthermore, a vibration roller is provided on the inner side of the conveyor belt, and the vibration roller is located above the liquid supply pipe and contacts with the conveyor net of the conveyor belt, so that the conveyor net of the conveyor belt forms a vibration zone in the atomized liquid channel.

[0010] Furthermore, connecting plates are provided at both ends of the vibration roller, an elastic connecting piece is connected between the connecting plate and the vibration roller, and the connecting plate is fixed on the conveyor belt.

[0011] Furthermore, the vibration roller includes a hollow roller and a vibration motor fixed to the inner wall of the hollow roller, and both ends of the hollow roller are connected to the conveyor belt.

[0012] Furthermore, a rotating roller is sleeved on the outer side of the hollow roller, and the rotating roller is rotatably connected to the outer side of the hollow roller via a bearing.

[0013] Furthermore, a rubber roller is sleeved and fixed on the outer side of the rotating roller.

[0014] Furthermore, a support frame is provided on the conveyor belt, and the negative pressure assembly is connected to the support frame.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: 1. By arranging an upward spraying atomizing component on the inner side of the conveyor belt, and arranging a negative pressure component above the conveyor belt to extract the air above the conveyor belt, an atomized liquid channel flowing from bottom to top is formed on the conveyor belt. The glass bottles pass through the atomized liquid channel in sequence under the conveyance of the conveyor belt. The atomized liquid adheres to the outer wall of the glass bottle to form a coating.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0021] like Figure 1 As shown, the present invention proposes a cold-end spraying device for glass bottles, comprising a conveyor belt 1, a negative pressure component and an atomization component.

[0022] It should be understood that the conveyor belt 1 is led out of the annealing furnace, and the glass bottles pass through the annealing furnace for annealing under the transmission of the conveyor belt 1, and the negative pressure component and the atomization component are located at the port at the outlet end of the annealing furnace. In order to ensure that the glass bottles are heated evenly during annealing, the conveyor belt 1 adopts a mesh chain conveyor belt, with a mesh belt in the middle and chains on both sides, and is driven by sprockets.

[0023] The negative pressure component is arranged above the conveyor belt 1 and arranged perpendicular to the conveying direction of the conveyor belt 1. A support frame 11 is provided on the conveyor belt 1. The negative pressure component is connected to the support frame 11. The air above the conveyor belt 1 is extracted by the negative pressure component to form a negative pressure above the conveyor belt 1. The atomization component is arranged on the inner side of the conveyor belt 1 and arranged perpendicular to the conveying direction of the conveyor belt 1. The output end of the atomization component faces upward, and the atomization component is located directly below the negative pressure component. The atomizing assembly is located inside the conveying net of the conveyor belt 1 and directly below the negative pressure assembly, and the output end of the atomizing assembly faces upward, and the output end of the atomizing assembly can spray the atomizing agent upward. Since the conveyor belt 1 adopts a mesh chain conveyor belt, under the negative pressure suction of the negative pressure assembly, the atomizing agent can pass through the conveying net of the conveyor belt 1 and be sucked into the negative pressure assembly, so that an atomizing liquid channel flowing from bottom to top is formed between the atomizing assembly and the negative pressure assembly (such as Figure 4As shown in the figure, when the glass bottle on the conveyor belt 1 moves to the atomized liquid channel area, the atomized liquid flows along the bottle body of the glass bottle under the action of the wall attachment effect, and can adhere to the outer wall of the glass bottle to form a coating. Moreover, since the atomized liquid flows from bottom to top and is sucked out by the negative pressure component, the atomized liquid will not enter the bottle from the bottle mouth at the top of the glass bottle, thereby avoiding contamination of the interior of the glass bottle, and can be sprayed on the bottom of the glass bottle to increase the adhesion area of ​​the coating.

[0024] In an optional embodiment, the support frame 11 adopts one of a fixed-height frame or a height-adjustable frame, and preferably adopts a height-adjustable frame. By adjusting the frame, the height of the negative pressure component is adjusted. When the height of the glass bottle body is high, the height of the negative pressure component is increased to avoid interference with the glass bottle. When the height of the glass bottle body is short, the height of the negative pressure component is lowered to reduce the distance between the negative pressure component and the conveyor belt 1. While satisfying the negative pressure suction force, the output power of the negative pressure component can be reduced.

[0025] Furthermore, a driving component 6 is provided on one side of the conveyor belt 1, and one end of the atomizing assembly is connected to the output end of the driving component 6. The driving component 6 is configured to drive the atomizing assembly to swing back and forth, so that the output direction of the atomizing assembly is inclined, and the spraying direction of the atomizer swings back and forth in a fan shape (such as Figure 5 and Figure 6 shown); When the atomizing assembly swings back and forth, the spraying direction of the atomizer forms a certain inclination angle with the body of the glass bottle, and swings back and forth across the bottle body, increasing the lateral disturbance of the atomized liquid, so that the atomized liquid can better cover the bottle body and avoid dead corners in spraying.

[0026] In a specific embodiment, the negative pressure assembly includes a plurality of wind collecting hoods 2 (such as Figure 2 As shown in the figure, the wind collecting hood 2 is provided with an enlarged end and a narrowed end. The enlarged end of the wind collecting hood 2 faces downward to increase the wind collecting area. The narrowed end of the wind collecting hood 2 is provided with an induced draft fan 21. The input end of the induced draft fan 21 is connected to the narrowed end of the wind collecting hood 2 through a pipeline. The enlarged ends of the multiple wind collecting hoods 2 are mutually attached along the width direction of the conveyor belt 1 and cover the width of the conveyor belt 1, so that the atomizer sprayed by the atomizing assembly can be sucked by the wind collecting hood 2. The air in the wind collecting hood 2 is extracted by the induced draft fan 21, so that the enlarged end of the wind collecting hood 2 is in a negative pressure state, so that the air above the conveyor belt 1 flows toward the enlarged end of the wind collecting hood 2. Correspondingly, under the action of the airflow, the atomizer sprayed by the atomization component can pass through the conveyor belt 1 and flow and converge toward the enlarged end of the wind collecting hood 2, forming an atomized liquid channel flowing from bottom to top. The sprayed atomized liquid is finally pumped and discharged by the induced draft fan 21, so as to prevent the atomizer from settling downward into the interior of the glass bottle.

[0027] In an optional embodiment, the induced draft fan 21 is a centrifugal fan, which has a high exhaust capacity, increases the exhaust volume above the conveyor belt 1, and further increases the negative pressure suction force on the atomized liquid.

[0028] Furthermore, the narrowed end of each air collecting hood 2 is connected to two induced draft fans 21, and the two induced draft fans 21 act simultaneously to increase the negative pressure suction force of the enlarged end of the air collecting hood 2, thereby avoiding the phenomenon of atomizer scattering.

[0029] Furthermore, the negative pressure component also includes an exhaust pipe 22, and the output ends of multiple induced draft fans 21 are all connected to the exhaust pipe 22, and the exhaust pipe 22 is connected to an external gas-liquid separation device. Multiple induced draft fans 21 transport the pumped atomizer to the external gas-liquid separation device through the exhaust pipe 22, and the external gas-liquid separation device performs gas-liquid separation. The recovered solvent can be transported to the external liquid supply device for utilization again.

[0030] In a specific embodiment, the atomizing assembly includes a liquid supply pipe 3 arranged perpendicular to the conveying direction of the conveyor belt 1, and multiple atomizing heads 31 are connected to both sides of the liquid supply pipe 3, and the multiple atomizing heads 31 are evenly distributed along the length direction of the liquid supply pipe 3 (such as Figure 2 and Figure 3 As shown), one end of the liquid supply pipe 3 is connected to an external liquid supply device; The external liquid supply device provides atomizer to the atomizer head 31 through the liquid supply pipe 3, and the atomizer head 31 atomizes and sprays the atomizer. The atomizer spraying area of ​​the multiple atomizer heads 31 can cover the width of the conveyor belt 1, so that the glass bottles on the conveyor belt 1 can be atomized and sprayed after passing through the atomizer assembly position; In an optional embodiment, the atomizing head 31 adopts an ultrasonic atomizing nozzle, which atomizes finer particles and improves the spraying quality.

[0031] The other end of the liquid supply pipe 3 is connected to the output end of the driving component 6. The driving component 6 drives the liquid supply pipe 3 to swing back and forth along its own axis, so that the atomizing head 31 on the liquid supply pipe 3 swings, and then the spraying direction of the atomizer swings in a fan shape.

[0032] In an optional embodiment, the driving component 6 includes a stepping motor, which can control the rotation direction and rotation angle, thereby driving the liquid supply tube 3 to perform reciprocating rotation and swing at a certain angle.

[0033] Combination Figure 2 and Figure 4As shown, a vibration roller 4 is provided on the inner side of the conveyor belt 1. The vibration roller 4 is located above the liquid supply pipe 3 and contacts with the conveying net of the conveyor belt 1, so that the conveying net of the conveyor belt 1 forms a vibration area in the atomized liquid channel. The conveyor belt 1 running in the atomized liquid channel area is driven by the vibration roller 4 to vibrate, and the glass bottles on the conveyor belt 1 vibrate accordingly. By controlling the power of the vibration roller 4, the glass bottles vibrate slightly. When the glass bottles vibrate, the glass bottles bounce up and down slightly, so that the bottom area of ​​the glass bottle that was originally in contact with the conveyor belt 1 is separated from the conveyor belt 1, and then the area of ​​the bottom of the glass bottle that was originally blocked by the conveyor belt 1 can be attached by the atomizer, completing the coating of the entire bottom of the glass bottle, avoiding wear of the bottom of the glass bottle due to uneven coating in the subsequent production process.

[0034] Combination Figure 7 As shown, connecting plates 5 are provided at both ends of the vibration roller 4, and elastic connecting members 51 are connected between the connecting plates 5 and the vibration roller 4. The connecting plates 5 are fixed on the fixed bracket of the conveyor belt 1. The vibration of the vibration roller 4 is buffered by the elastic connecting member 51 to prevent the vibration from being transmitted to the fixed bracket of the conveyor belt 1.

[0035] In an optional embodiment, the elastic connector 51 is made of either rubber or metal springs, preferably metal springs. Compared with rubber, metal springs are less susceptible to corrosion and aging. After long-term use, they still have good elasticity and a long service life, thereby reducing subsequent maintenance costs.

[0036] Combination Figure 8 As shown, the vibration roller 4 includes a hollow roller 41 and a vibration motor 42 fixed on the inner wall of the hollow roller 41. Both ends of the hollow roller 41 are connected to the conveyor belt 1. The vibration motor 42 drives the hollow roller 41 to vibrate, and the hollow roller 41 transmits the vibration to the conveying net of the conveyor belt 1, so that the conveying net can form a vibration zone. By controlling the output power of the vibration motor 42, the glass bottle generates a small amplitude vibration on the conveying net, which satisfies the adhesion of the atomized liquid to the bottom of the bottle and prevents the glass bottle from tipping over.

[0037] Furthermore, a rotating roller 43 is sleeved on the outer side of the hollow roller 41, and the rotating roller 43 is rotatably connected to the outer side of the hollow roller 41 through a bearing. When the conveying net of the conveyor belt 1 is pulled, it contacts the rotating roller 43, so that the rotating roller 43 can be dragged and rotated, converting the sliding friction into rotational friction, thereby reducing the wear on the conveying net.

[0038] Furthermore, a rubber roller 44 is fixedly sleeved on the outer side of the rotating roller 43 . The rubber roller 44 is relatively soft in texture, and the wear on the conveyor belt 1 is further reduced during vibration.

[0039] The working principle of the present invention is as follows: the glass bottles are placed on the conveyor belt 1. Since the conveyor belt 1 runs through the annealing furnace, the glass bottles enter the annealing furnace from the annealing furnace entrance under the conveyance of the conveyor belt 1, pass through the inside of the annealing furnace, complete annealing, and then are output from the annealing furnace outlet. After the glass bottles are output from the annealing furnace outlet, they move toward the atomizing component and the negative pressure component under the conveyance of the conveyor belt 1. The induced draft fan 21 extracts the air above the conveyor belt 1 through the wind collecting hood 2. Multiple atomizing heads 31 spray atomizing agents upward. Under the action of negative pressure, an atomizing liquid channel flowing from bottom to top is formed on the conveyor belt 1. The glass bottles pass through the atomizing liquid channel in turn under the conveyance of the conveyor belt 1. The atomizing liquid adheres to the outer wall of the glass bottle to form a coating, and the atomizing liquid will not enter the inside of the glass bottle, avoiding pollution to the inside of the glass bottle. At the same time, the atomizing liquid can also be sprayed on the bottom of the glass bottle, eliminating the disadvantage that the original spray flowing from top to bottom cannot be sprayed on the bottom of the glass bottle. During the spraying process of the atomizing head 31, the driving component 6 drives the liquid supply pipe 3 to swing back and forth along its own axis, so that the atomizing head 31 on the liquid supply pipe 3 swings, and then the spraying direction of the atomizer swings back and forth in a fan shape (such as Figure 5 and Figure 6 As shown), at this time, the spray direction of the atomizer forms a certain inclination angle with the body of the glass bottle, and reciprocates to sweep across the bottle body, increasing the lateral disturbance of the atomized liquid, so that the atomized liquid can better cover the bottle body and avoid spraying dead corners; When the conveyor belt 1 moves to the atomized liquid channel area, the conveyor belt 1 is driven by the vibration roller 4 to vibrate, so that the conveying network of the conveyor belt 1 forms a vibration area in the atomized liquid channel, and the glass bottles on the conveyor belt 1 vibrate accordingly. When the glass bottles vibrate, the glass bottles will bounce up and down slightly, so that the bottom area of ​​the glass bottle that was originally in contact with the conveyor belt 1 is separated from the conveyor belt 1, and the area of ​​the bottom of the glass bottle that was originally blocked by the conveyor belt 1 can be attached by the atomizer, completing the coating of the entire bottom of the glass bottle, thereby avoiding wear of the bottom of the glass bottle due to uneven coating in the subsequent production process.

[0040] In summary of the above embodiments: by arranging an atomizing component that sprays upward on the inner side of the conveyor belt 1, and arranging a negative pressure component that extracts the air above the conveyor belt 1 above the conveyor belt 1, an atomized liquid channel that flows from bottom to top is formed on the conveyor belt 1, and the glass bottles pass through the atomized liquid channel in sequence under the conveyance of the conveyor belt 1, and the atomized liquid adheres to the outer wall of the glass bottle to form a coating, and the atomized liquid will not enter the inside of the glass bottle, avoiding contamination of the inside of the glass bottle. At the same time, the atomized liquid can also spray the bottom of the glass bottle, eliminating the disadvantage that the original spray flowing from top to bottom cannot spray the bottom of the glass bottle; The driving component 6 is set to drive the atomizing assembly to swing, so that the spraying direction of the atomizer swings back and forth in a fan shape. At this time, the spraying direction of the atomizer forms a certain inclination angle with the bottle body of the glass bottle, and swings back and forth to sweep across the bottle body, increasing the lateral disturbance of the atomized liquid, so that the atomized liquid can better cover the bottle body and avoid the occurrence of spraying dead angles; By arranging a vibration roller 4 in the area of ​​the conveyor belt 1 located in the atomized liquid channel, the conveyor belt 1 is driven by the vibration roller 4 to vibrate, and the glass bottles on the conveyor belt 1 vibrate accordingly, causing a small up and down bounce, so that the bottom area of ​​the glass bottle that was originally in contact with the conveyor belt 1 is separated from the conveyor belt 1 and is attached by the atomizer, completing the coating of the entire bottom of the glass bottle, thereby avoiding wear of the bottom of the glass bottle due to uneven coating in the subsequent production process.
