Description

Technical Field

[0001] The utility model relates to bottle washing equipment, in particular to a bottle washing nozzle and a bottle washing device. Background Art

[0002] The existing fully automatic bottle rinser mainly includes a conveying mechanism, a rinsing mechanism, a machine frame and other parts. The rinsing mechanism includes a guide tube, a nozzle and the like. The existing nozzle mechanism is generally a movable nozzle. When rinsing, the bottle body needs to be inverted, and the nozzle is located at the lower side of the bottle mouth of the inverted bottle body and penetrates into the bottle body. In the existing method, the general nozzle is either for single liquid rinsing, which requires a blow-drying operation at another station, or a gas-liquid integrated nozzle is used for rinsing and blow-drying. The former is not easy to air-dry the retained water in the bottle body after rinsing, and a complete set of blow-drying devices is required. The latter adopts an integrated nozzle to achieve rinsing and blow-drying. Therefore, after rinsing and drying, the water retained in the nozzle is sprayed into the bottle body again. At the same time, after air drying, since the bottle body needs to be turned over, the conventional nozzle also needs to move with it. During the following process, the liquid droplets in the tube body will drip into the bottle body, so there is still retained water in the bottle body, and the quality of rinsing and drying cannot be guaranteed. Summary of the Invention

[0003] The purpose of the utility model is to provide a bottle washing nozzle and a bottle washing device in view of the deficiencies in the prior art.

[0007] The plug thread is engaged with the mounting hole at the lower end of the liquid inlet pipe.

[0008] The liquid inlet pipe is vertically arranged, and the inner cavity of the pipe section of the liquid inlet pipe located downstream of the liquid inlet manifold forms a liquid storage cavity.

[0009] The cannula comprises an inner tube and an outer tube, the downstream section of the outer tube is hollowly sleeved on the downstream section of the inner tube, and the upstream end of the inner tube passes through the bent section of the outer tube and is sealed with the bent section.

[0010] The movable valve core is a columnar or spherical valve core, and the movable valve core is made of bronze, stainless steel, plastic, nylon, ceramic or glass.

[0012] The liquid inlet manifold and the drain pipe are respectively located on both sides of the liquid inlet pipe, wherein the liquid inlet manifold is located on the side of the liquid inlet pipe close to the rotation center of the turnover frame, and the drain pipe is located on the side of the liquid inlet pipe away from the rotation center of the turnover frame.

[0013] The above-mentioned scheme includes a cannula and a liquid inlet pipe, wherein the cannula has two flow channels, and the upstream end of the first flow channel of the two flow channels is connected to the air inlet pipe, wherein the second flow channel is connected to the liquid inlet pipe section located between the first valve hole and the upstream end of the emptying pipe through the liquid inlet manifold, and a matching tube cavity of the valve core is formed between the first valve hole and the liquid inlet pipe section upstream of the emptying pipe, and a sliding matching movable valve core is formed in the matching tube cavity, and the matching tube cavity includes a first tube cavity located upstream of the liquid inlet manifold and a second tube cavity located downstream of the liquid inlet manifold. When the movable valve core is located in the first tube cavity, the liquid inlet manifold is connected to the emptying pipe through the matching tube cavity, and when the movable valve core is located in the second tube cavity, the liquid inlet manifold is connected to the upstream end of the liquid inlet pipe through the matching tube cavity. A first valve hole is set at the upstream end of the first tube cavity, and an elastic element for driving the movable valve core to be normally closed to the first valve hole is set in the liquid inlet pipe. The above scheme has the following beneficial effects: the cannula is used to be inserted into the bottle body, and the two flow channels in the cannula are used for water supply and flushing and air drying when washing the bottle, respectively; the movable valve core can be pressed and moved in the matching tube cavity to overcome the elastic force of the elastic element; when the bottle body is being cleaned, the liquid inlet pipe enters the high-pressure water flow, and the movable valve core is pressurized to overcome the elastic force and move in the matching tube cavity until it moves to the second tube cavity; the liquid inlet manifold is connected to the liquid inlet pipe through the matching tube cavity, and the high-pressure water flow in the liquid inlet pipe is sprayed into the bottle body through the liquid inlet manifold; when cleaning After completion, when the bottle interior needs to be blown dry, air enters the inlet manifold through the first channel. Simultaneously, since water injection into the liquid inlet pipe has ceased, the movable valve core elastically closes, allowing air in the first channel to dry the bottle interior. Some of this moisture-laden air is blown out through the bottle opening. The injected air creates a high-pressure zone within the bottle, while another portion of the moisture-laden air forces the stagnant liquid column in the second channel back into the downstream portion of the liquid inlet pipe, where it is further discharged through the exhaust pipe. Meanwhile, the moisture-laden air continues to be blown out. Throughout the drying process, the liquid inlet manifold forms an airway, facilitating the partial discharge of air from the bottle. In the final stages of drying, the entire inlet manifold is free of liquid, and no liquid from the cannula drips into the rapidly drying or already dried bottle. The inlet manifold is used to deliver flushing liquid early in the process. It also facilitates drainage during the initial drying phase and facilitates the discharge of moisture-laden air. In the final stages of drying, there is no risk of liquid from the inlet manifold leaking into the bottle. It can ensure that the dried bottle body always remains dry.

The bottle is clamped by the clamping device and then flipped by the turning frame, inverted, for rinsing and drying. After drying, the bottle is returned to the conveying device and, in an upright position, transported to the next process.

[0024] See also Figures 1 to 3An embodiment of the bottle washing nozzle, the bottle washing nozzle comprises a nozzle tube 100 and a liquid inlet pipe 200, the nozzle tube 100 has two flow channels, a first flow channel 110 of the two flow channels is connected with the air inlet pipe 700 at an upstream end, the liquid inlet pipe 200 is provided with a first valve hole 201 at an upstream end, wherein a second flow channel 120 is communicated with a pipe section of the liquid inlet pipe 200 between the first valve hole 201 and an upstream end of the emptying pipe 300 through a liquid inlet manifold 210, a matching pipe cavity 205 of the valve core is formed between the first valve hole 201 and the pipe section of the liquid inlet pipe 200 upstream of the emptying pipe, an active valve core 400 is slidably matched in the matching pipe cavity 205, the matching pipe cavity 205 comprises a first pipe cavity 2051 upstream of the liquid inlet manifold 210 and a second pipe cavity 2052 downstream of the liquid inlet manifold, when the active valve core 400 is located in the first pipe cavity 2051, the liquid inlet manifold 210 is communicated with the emptying pipe 300 through the matching pipe cavity 205, when the active valve core 400 is located in the second pipe cavity 2052, the liquid inlet manifold 210 is communicated with the upstream end of the liquid inlet pipe 200 through the matching pipe cavity 205, the liquid inlet pipe 200 is provided with an elastic element 410 for driving the active valve core 400 to be normally closed to the first valve hole 201.

[0025] By the above scheme, the nozzle tube 100 is used for being inserted into the bottle, the two flow channels in the nozzle tube 100 are respectively used for water supply and flushing and air blowing and drying during bottle washing, wherein the active valve core 400 can be moved under pressure in the matching pipe cavity 205 to overcome the elastic force of the elastic element 410, when the bottle is washed, the liquid inlet pipe 200 enters the high-pressure water flow, the active valve core 400 is moved in the matching pipe cavity 205 under the pressure to overcome the elastic force until it is moved to the second pipe cavity 2052, the liquid inlet manifold 210 is communicated with the liquid inlet pipe through the matching pipe cavity 205, the high-pressure water flow in the liquid inlet pipe 200 is sprayed into the bottle through the liquid inlet manifold 210, when the bottle is dried after washing, the air enters the first flow channel 110 through the air inlet pipe 700, and the active valve core 400 is closed under the elastic action because the liquid inlet pipe 200 stops water injection, the air in the first flow channel 110 blows the bottle, part of the air carrying water vapor is blown out through the bottle opening, because the air is injected into the bottle, a high-pressure side is formed in the bottle, another part of the air carrying water vapor forces the liquid column in the second flow channel 120 to flow back and enter the downstream of the liquid inlet pipe 200 and further be discharged through the emptying pipe 300, and the air carrying water vapor continuously blows out.

[0026] Throughout the drying process, the liquid inlet manifold 210 forms an air passageway, facilitating the partial discharge of air from the bottle. In the final stages of drying, no liquid column remains in the entire liquid inlet manifold 210, and no liquid drips from the entire cannula 100 into the rapidly drying or already dried bottle. The liquid inlet manifold 210 is used to deliver flushing liquid in the early stages of the drying process. It also facilitates drainage at the beginning of drying and facilitates the discharge of air carrying moisture. In the final stages of drying, there is no risk of liquid flowing into the bottle from the liquid inlet manifold 210. This ensures that the dried bottle remains dry.

[0027] In some embodiments, the liquid inlet pipe 200 is provided with a first valve hole 201 and a second valve hole 702. The second flow channel 120 communicates with the section of the liquid inlet pipe 200 located between the first valve hole 201 and the second valve hole 702 via the liquid inlet manifold 210. The second valve hole 702 is located at the upstream end of the exhaust pipe 300. The provision of the valve holes enables a seal with the movable valve core 400. A low-pressure region is formed at the second valve hole 702, where the movable valve core 400 resides, cooperating with the second valve hole 702 to form a seal.

[0028] In some embodiments, the liquid inlet pipe 200 is a straight pipe with an inlet at its first end and a plug 420 at its second end. The elastic element 410 is a compression spring, with its first end acting on the movable valve core 400 and its second end acting on the plug 420. This structural design facilitates the placement of the elastic element 410, while simplifying the structure of the liquid inlet pipe 200. The compression spring moves smoothly within the straight pipe, and the compression spring keeps the movable valve core 400 normally closed against the first valve hole 201. This normally closed structure prevents liquid upstream of the first valve hole 201 from moving within the pipe in the absence of water supply pressure, particularly when the liquid column within the pipe sways during nozzle movement. Furthermore, in the normally closed state, air containing water vapor can be expelled in the opposite direction through the liquid inlet manifold 210. The normally closed structure is easily pushed open by water supply pressure, but under gas pressure, it helps the compression spring further press against the first valve hole 201, ensuring a high degree of sealing.

[0029] In some embodiments, the plug 420 is threadedly engaged with the mounting hole at the lower end of the liquid inlet pipe 200. This structure facilitates maintenance of the spring or valve core. Furthermore, the depth of screwing the plug 420 in can be used to adjust the preload force on the movable valve core 400, thereby adjusting the tightness with the first valve hole 201. It can also adjust the size of the channel formed between the upstream end of the drain pipe 300 and the movable valve core 400, thereby controlling the exhaust and drain flow rates. In some embodiments, the liquid inlet pipe 200 is vertically arranged, and the inner cavity of the liquid inlet pipe 200 downstream of the liquid inlet manifold 210 forms a liquid reservoir. This reservoir can store trace amounts of leaked liquid for a relatively short period of time. This structure can reduce the sealing requirements for the first valve hole 201 and the movable valve core 400.

[0030] In some embodiments, the cannula 100 includes an inner tube 130 and an outer tube 140. The downstream section of the outer tube 140 is hollowly inserted into the downstream section of the inner tube 130, and the upstream end of the inner tube 130 passes through the bent section 141 of the outer tube 140 and is sealed to the bent section 141. The movable valve core 400 is a cylindrical or spherical valve core and is made of bronze, stainless steel, plastic, nylon, ceramic, or glass. The columnar or spherical valve core can adapt to the lumen of the liquid inlet pipe 200 and can move smoothly in the lumen. The special columnar valve core can move under the pressure of water pressure. One end of the columnar valve core is first engaged in the second lumen 2052, and the first end of the columnar valve core is engaged in the first lumen 2051. Even if the movable valve core 400 is forced and moves at a lower speed, it can prevent the upstream port of the liquid inlet manifold 210, the first lumen 2051 and the second lumen 2052 from being connected for a short time, which can save water resources. At the same time, the second lumen 2052 can always maintain low pressure during the movement of the movable valve core 400, so that the movable valve core 400 responds quickly.

[0031] The utility model also provides an embodiment of a bottle washing device, see Figures 1 to 3 The bottle washing device includes a frame 500, a conveying device 600, and the aforementioned bottle washing nozzle. The frame 500 is provided with a reversible turning frame 510, on which a clamping device 520 for clamping the bottle body is provided. The frame 500 is provided with a conveying device 600, which is located below the clamping device 520. The frame 500 is provided with a bottle washing nozzle that can be fed in a vertical direction. The feeding method can be achieved by a linear motion mechanism, such as a slide rail assembly and a cylinder. The bottle washing nozzle is installed on the slide rail of the slide rail assembly, and the slide rail assembly slider is fixed, and the slide rail is connected to the push cylinder; or the slide rail is fixed, and the bottle washing nozzle is provided on the slider, or connected to the slider via a bracket, and the slider is connected to the push cylinder. The liquid inlet pipe 200 of the bottle washing nozzle is connected to a flexible water supply pipe, and the air inlet pipe 700 is connected to a flexible air supply pipe.

[0032] It can be understood that the bottle body is clamped by the clamping device 520, and the clamping device 520 may include a pair of clamps that can move toward each other, at least one of which has a power device to clamp or loosen. The bottle body is clamped by the clamping device 520, and then flipped by the flip frame 510 to make the bottle body inverted for rinsing and drying. After drying, the bottle body is placed back on the transmission device 600, in the upright state, and continues to be transmitted to the next process. The transmission device 600 can be a plate conveyor or a belt conveyor, or other conveying device that can transfer the bottle body in a straight line.

[0033] In some embodiments, the liquid inlet manifold 210 and the drain pipe 300 are located on either side of the liquid inlet pipe 200, with the liquid inlet manifold 210 located on the side of the liquid inlet pipe 200 closer to the center of rotation of the flip frame 510, and the drain pipe 300 located on the side of the liquid inlet pipe 200 farther from the center of rotation of the flip frame 510. With this structure, liquid remaining in the liquid inlet pipe 200 will not enter the liquid inlet manifold 210 due to centrifugal force during the flipping of the flip frame 510. In particular, when a liquid reservoir is provided, this portion of liquid will not enter the liquid inlet manifold 210, thereby preventing droplets from entering the dried bottle.

[0034] The utility model has a simple and compact structure, can complete flushing and drying at the same work station, has high working efficiency, and can ensure the quality of flushing and drying.
