[0057] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0058] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0059] As described in the background section, existing high-temperature steam equipment often uses a conveyor belt to move the cans and sprays steam through steam nozzles on both sides or the top to sterilize the cans. However, due to the inherent characteristics of high-temperature steam, the steam floats upward after being sprayed out, making it difficult to move through the can opening to the inside of the can, resulting in an unsatisfactory sterilization effect inside the can.

[0060] Example 1:

[0061] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a can container sterilization device, such as... Figure 1 As shown, the canned food container sterilization equipment includes:

[0062] Conveyor component 400, such as Figure 4 As shown, the conveying assembly includes a conveying device 410, on the surface of which a tray containing an array of cans is placed;

[0063] Steam assembly 100, such as Figure 3 As shown, the steam assembly includes a steam nozzle 120, which corresponds to the arrangement of the can array;

[0064] A power assembly 200 drives a conveying assembly to move so that a steam nozzle extends into the interior of the can.

[0065] In this embodiment, the conveying device can be directly connected to the infeed conveyor and the outfeed conveyor. The infeed conveyor transports the tray containing the array of cans to the conveying device. The conveying device moves the tray to the position of the steam nozzle. Then, the power component drives the conveying component to move the cans toward the steam nozzle until the steam nozzle extends into the can. At this time, the steam source is turned on, and high-temperature steam is sprayed into the can through the steam nozzle, thereby sterilizing the inside of the can.

[0066] This embodiment allows high-temperature steam to be sprayed directly inside the can, thereby achieving high-temperature disinfection and sterilization of the can's interior.

[0067] In this embodiment, as Figure 5 As shown, the conveying assembly also includes a positioning mechanism 420, which is disposed on one side of the conveying device;

[0068] like Figure 8 As shown, the positioning mechanism includes:

[0069] The fourth power unit 421 is fixedly installed on one side of the conveying device;

[0070] Positioning plate 422 is driven to move linearly by a fourth power unit to block the pallet on the conveying device at the position corresponding to the steam nozzle.

[0071] In this embodiment, the positioning plate can be linearly moved by the fourth power device, thereby extending it to prevent the pallet from continuing to move with the conveying device and keeping the pallet at the position of the steam nozzle. This allows the steam nozzle to extend from the can opening into the can when the power component moves the pallet, thus achieving pallet positioning.

[0072] In this embodiment, the fourth power unit can be selected from a cylinder, electric cylinder, hydraulic cylinder, motor-gear rack and pinion structure, motor-screw transmission structure, or other power units capable of achieving linear movement of the positioning plate. In addition, the positioning mechanism may also include a fixing part, through which the fourth power unit can be fixed to the side of the conveying device. The fixing method between the fixing part and the conveying device includes, but is not limited to, welding, fusion, riveting, bolt connection, screw connection, or other connection methods that maintain relative fixation between the fixing part and the conveying device.

[0073] In addition, such as Figure 5 As shown, the conveying assembly may further include a displacement mechanism 430, which drives the conveying device to move linearly so that the conveying device can be connected with the infeed conveying or the outfeed conveying.

[0074] like Figure 7 As shown, the displacement mechanism includes:

[0075] Fifth power unit 431;

[0076] The slide plate 432 is fixedly installed on the slide plate, and the slide plate is driven to move linearly by the fifth power device.

[0077] In this embodiment, the fifth power device drives the conveying device to move linearly, thereby connecting the conveying device with the inbound or outbound pallet conveying to receive or send out pallets. Through the above method, a certain clearance space is provided between the conveying device and the inbound or outbound pallet conveying, thereby avoiding interference with the operation of the equipment caused by the inbound or outbound pallet conveying.

[0078] In this embodiment, the displacement mechanism may further include a mounting part, the fifth power device is fixedly mounted on the mounting part, and the slide plate can be slidably connected to the mounting part through the guide mechanism 433. Limiters may also be provided at both ends of the guide mechanism to limit the movement stroke of the slide plate. The fifth power device may be a cylinder, electric cylinder, hydraulic cylinder or other device that can realize the linear movement of the slide plate. The guide mechanism may be a guide rail-slider structure, guide rod-slider structure, slide groove-slider structure or other mechanism that can realize motion guidance.

[0079] Example 2:

[0080] This embodiment provides a steam nozzle arrangement, wherein the steam nozzle can be arranged above the conveying device.

[0081] At this time, as Figure 2 As shown, the power assembly may include a lifting mechanism 210, which drives the conveying device to slide vertically so that the steam nozzle extends into the can.

[0082] For example, such as Figure 4 As shown, the lifting mechanism may include a first power device 211 and a first slide 212. The first slide is connected to the first power device. In this embodiment, the first power device may be a cylinder, an electric cylinder, a hydraulic cylinder, or other device that can realize the linear movement of the first slide.

[0083] The conveying assembly is fixedly installed on the first carriage. The first power device drives the first carriage to rise, thereby driving the entire conveying assembly to rise, so that the array of cans on the conveying device gradually approaches the steam nozzle until the steam nozzle extends into the interior of the can.

[0084] In this embodiment, as Figure 2 As shown, the power assembly also includes a pressure plate mechanism 220, which fixes the canned food.

[0085] like Figure 4 , 5 As shown, the pressure plate mechanism includes:

[0086] Second power unit 222;

[0087] The pressure plate 221 is configured to correspond to the steam nozzle. A positioning hole 221A is provided on the surface of the pressure plate. The positioning hole defines and accommodates the mouth of the can. The positioning hole corresponds to the arrangement of the can array. The pressure plate is driven to move linearly by a second power device so that the mouth of the can enters or leaves the positioning hole.

[0088] In addition, the pressure plate mechanism may also include a second slide 223, which is connected to a second power device. The pressure plate is fixed to the top of the second slide. The second power device may be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, or other device capable of realizing linear movement of the second slide. The second slide may be slidably connected to the first slide via a guide rod.

[0089] Example 3:

[0090] This embodiment provides another arrangement of the steam nozzle, in which the steam nozzle is positioned below the conveying device.

[0091] Unlike Embodiment 2, the power assembly in this embodiment includes not only the lifting mechanism and the pressure plate mechanism, but also a tilting mechanism 230, which drives the pressure plate mechanism and the conveying assembly to tilt 180°.

[0092] like Figure 4 , 5 As shown, the flipping mechanism includes:

[0093] Mounting part 232, on which the conveying assembly and the pressure plate mechanism are both mounted;

[0094] The third power unit 231 drives the mounting part to rotate.

[0095] In this embodiment, the mounting part is pivotally mounted on the first carriage, and the third power device is fixedly mounted on the first carriage. The third power device includes, but is not limited to, a motor, a rotary cylinder, a rotary hydraulic cylinder, or other power devices capable of driving the mounting part to rotate. The second carriage is slidably connected to the mounting part through a guide mechanism, and the second power device is fixedly mounted on the surface of the mounting part away from the conveying component.

[0096] When the tray moves to the position of the steam nozzle, the second power unit drives the pressure plate to slide vertically down, so that the mouth of the can extends into the positioning hole. The pressure plate squeezes the mouth of the can and the body of the can to keep it fixed. Then the third power unit drives the can array to rotate 180°, and the lifting mechanism drives the can array to descend, so that it is close to the steam nozzle, until the steam nozzle passes through the positioning hole and extends into the can.

[0097] In this embodiment, as Figure 3 As shown, the steam assembly may also include a water collection tank 110, and the steam nozzle is disposed in the water collection tank.

[0098] The liquid liquefied by steam pre-cooling is collected in a water collection tank to prevent the liquid from dripping onto the ground and making the ground slippery.

[0099] In addition, a fixing plate 130 can be installed in the water collection tank, and the steam nozzle can be fixed on the fixing plate to provide support for the steam nozzle.

[0100] Example 4:

[0101] To prevent high-temperature steam from being directly released and causing burns, this embodiment proposes an optimization based on embodiment 1.

[0102] like Figure 1 As shown, an exhaust device 300 can be installed on one side of the steam assembly to discharge steam.

[0103] For example, such as Figure 9 , 10 As shown, the exhaust device includes:

[0104] The housing 310 has an air inlet 312 and an air outlet 311 on its outer side, and an air duct 313 communicating with the air inlet and the air outlet is provided inside the housing.

[0105] Condenser 320, which is installed in the air duct and connected to the refrigeration unit;

[0106] Fan 33, the fan is installed in the air duct, and the fan drives the air to flow;

[0107] The housing is also provided with a water collection chamber 314, a water collection pan communicating with the water collection chamber is provided below the condenser, and a drain outlet 340 is provided at the bottom of the water collection chamber.

[0108] like Figure 10 As shown, in this embodiment, the operation of the fan drives the airflow, and the steam flows into the air duct through the air inlet. When it passes through the condenser, it exchanges heat with the condenser, and the steam liquefies and drips into the water collection pan. It then collects in the water collection chamber along the water collection pan, thus realizing the treatment of steam and avoiding the safety hazards caused by the direct discharge of high-temperature steam.

[0109] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
