Description

Technical Field

[0001] This utility model relates to the field of plastic cup production technology, and in particular to a sterilization device for producing plastic yogurt cups. Background Technology

[0002] Plastic yogurt cups are disposable containers used to hold yogurt, typically made of food-grade plastic, such as polypropylene (PP) and polystyrene (PS). During the production of plastic yogurt cups, various microorganisms, such as bacteria, mold, and yeast, exist in the production environment. These microorganisms may adhere to the surface of the plastic cup. If not effectively sterilized, they will multiply rapidly after the yogurt is filled, causing it to spoil. Sterilization equipment ensures that plastic yogurt cups meet strict hygiene standards during production, preventing microbial contamination of the yogurt and protecting consumer food safety.

[0003] A search revealed that the document with publication number "CN218129307U" mentions "This utility model discloses a sterilization device for producing plastic yogurt cups, including a support box and a sterilization box. The sterilization box is fixedly installed on the upper surface of the support box, a door is movably installed on the front surface of the sterilization box, a control box is fixedly installed on one side surface of the sterilization box near the top, a steam spray pipe is fixedly installed on the upper inner surface of the sterilization box, a telescopic device is fixedly installed on the rear inner surface of the sterilization box, and a rotary motor is fixedly installed on the upper inner surface of the support box." A rotating base is fixedly installed at the output end of the motor and inside the sterilization chamber. A placement tray is movably installed on the upper surface of the rotating base. This invention provides a sterilization device for producing plastic yogurt cups. By incorporating a telescopic device, a rotating base, and a placement tray in a coordinated manner, it facilitates the placement and removal of plastic yogurt cups from the placement tray. However, while other devices sterilize plastic cups from top to bottom using steam nozzles, they cannot invert the cups, making it difficult for steam to reach the bottom, creating sterilization dead zones. This results in residual impurities not being thoroughly removed, affecting the hygienic quality of the product.

[0004] To address these issues, we provide a sterilization device for the production of plastic yogurt cups. Utility Model Content

[0005] The purpose of this invention is to provide a sterilization device for the production of plastic yogurt cups, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sterilization device for producing plastic yogurt cups, comprising a sterilization chamber and a flipping assembly. The flipping assembly is installed on the inner side of the sterilization chamber. The flipping assembly includes a support frame fixedly connected to the outer side of the sterilization chamber. A first motor is installed at the top of the support frame. A rotating shaft is connected to one end of the first motor via a key. Limiting frames are fixedly connected to both sides of the rotating shaft, and a positioning frame is fixedly connected to the other end of the rotating shaft.

[0007] Preferably, a first electric telescopic rod is installed on the upper surface of the bottom end of the support frame, and a limiting block is fixedly connected to the top end of the first electric telescopic rod. The limiting block and the limiting frame form a plug-in structure through a slot.

[0008] Preferably, a sliding bracket is fixedly connected to the outer end of the rotating frame, a sliding bracket is slidably connected to the inner side of the sliding bracket through a slot, a rigid perforated plate is fixedly connected to the top of the sliding bracket, and a perforated pad is fixedly connected to the top of the rigid perforated plate.

[0009] Preferably, the inner side of the rotating frame is slidably connected to a clamping frame via a slot, the clamping frame is internally threaded with an adjusting screw, and the top end of the adjusting screw is keyed to a second motor.

[0010] Preferably, a second electric telescopic rod is installed above the side wall of the slide frame, and a first push plate is fixedly connected to the telescopic end of the second electric telescopic rod; a third electric telescopic rod is installed below the side wall of the slide frame, and a second push plate is fixedly connected to the telescopic end of the third electric telescopic rod.

[0011] Preferably, a steam nozzle is installed on the upper interior of the sterilization chamber, and a steam duct is installed on the outer side of the steam nozzle.

[0012] Preferably, the outer end of the sterilization chamber is rotatably connected to a closed door via a hinge, the inner bottom of the sterilization chamber is fixedly connected to a collection box, the inside of the collection box is fixedly connected to a flow guide slope, and a flow guide pipe is installed on one side of the collection box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The flipping component provides a flipping function to flip the plastic cup, ensuring that all parts of the plastic cup are fully exposed within the steam nozzle range, reducing sterilization dead zones, removing residual impurities, and ensuring the hygienic quality of the product. During flipping, the second and third electric telescopic rods extend and retract, causing the first and second push plates to form a clamping structure on the left and right sides of one end of the sliding bracket. This drives the sliding bracket to move horizontally within the slide frame to the clamping frame. After the two sets of sliding brackets are aligned vertically, the second motor drives the adjusting screw to rotate, causing the two sets of clamping frames to move towards or away from each other along the rotating frame slot. This causes the perforated pad to abut against the plastic cup and provide elastic clamping. The first motor provides power to drive the rotating shaft to rotate, causing the rotating frame to rotate the clamped plastic cup. After flipping, the plastic cup is supported by another set of perforated pads and, after being moved, continues to be exposed to the steam nozzle for flipping sterilization.

[0015] 2. The sterilization chamber is sealed by a closed door to reduce steam escape and ensure sterilization effect. High-pressure steam from the outside is introduced into the steam nozzle through a steam pipe. The steam nozzle sprays steam to cover the plastic cup for sterilization. After the moisture condenses, it is discharged through the holes of the rigid perforated plate and the perforated pad, falls into the collection box, and is guided by the guide slope to be discharged to the outside through the guide pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, a sterilization device for producing plastic yogurt cups includes a sterilization chamber 1 and a flipping assembly 2. The flipping assembly 2 is installed on the inner side of the sterilization chamber 1. The flipping assembly 2 includes a support frame 201 fixedly connected to the outer side of the sterilization chamber 1. A first motor 202 is installed at the top of the support frame 201. A rotating shaft 203 is connected to one end of the first motor 202 with a flat key. Limiting frames 204 are fixedly connected to both sides of the rotating shaft 203. A rotating frame 207 is fixedly connected to the other end of the rotating shaft 203. The support frame 201 provides support, and the first motor 202 provides power to drive the rotating shaft 203 to rotate, causing the rotating frame 207 to rotate the clamped plastic cup.

[0023] Furthermore, a first electric telescopic rod 205 is installed on the upper surface of the bottom end of the support frame 201. A limiting plug 206 is fixedly connected to the top end of the first electric telescopic rod 205. The limiting plug 206 and the limiting frame 204 form a plug-in structure through a slot. By telescopically controlling the first electric telescopic rod 205, the limiting plug 206 moves up and down and plugs into the limiting frame 204, thereby completing the rotation limiting control of the rotating shaft 203 and preventing the rotating shaft 203 from deflecting and causing the plastic cup to tilt and slip.

[0024] Furthermore, a sliding bracket 208 is fixedly connected to the outer end of the rotating bracket 207, and a sliding bracket 209 is slidably connected to the inner side of the sliding bracket 208 through a slot. A rigid perforated plate 210 is fixedly connected to the top of the sliding bracket 209, and a drain pad 211 is fixedly connected to the top of the rigid perforated plate 210. The rigid perforated plate 210 and the drain pad 211 provide support for the plastic cup and prevent the accumulation of condensate through the holes.

[0025] Furthermore, a clamping frame 212 is slidably connected to the inner side of the rotating frame 207 via a slot. An adjusting screw 213 is threadedly connected to the inside of the clamping frame 212. A second motor 214 is connected to the top of the adjusting screw 213 via a flat key. The second motor 214 drives the adjusting screw 213 to rotate, causing the two sets of clamping frames 212 to move towards or away from each other along the slot of the rotating frame 207, thereby causing the drain pad 211 to abut against the plastic cup and provide elastic clamping.

[0026] Furthermore, a second electric telescopic rod 215 is installed on the upper side wall of the slide rack 208. The telescopic end of the second electric telescopic rod 215 is fixedly connected to the first push plate 216. A third electric telescopic rod 217 is installed on the lower side wall of the slide rack 208. The telescopic end of the third electric telescopic rod 217 is fixedly connected to the second push plate 218. The extension and retraction of the second electric telescopic rod 215 and the third electric telescopic rod 217 cause the first push plate 216 and the second push plate 218 to form a clamping structure on the left and right sides of one end of the sliding bracket 209, which drives the sliding bracket 209 to move horizontally within the slide rack 208 to the clamping frame 212. The movement can make the two sets of sliding brackets 209 staggered, ensuring that there is no top obstruction during steam sterilization.

[0027] Furthermore, a steam nozzle 3 is installed on the upper part of the sterilization chamber 1, and a steam conduit 4 is installed on the outside of the steam nozzle 3. High-pressure steam from the outside is introduced into the steam nozzle 3 through the steam conduit 4, and the steam nozzle 3 sprays steam to cover the plastic cup for sterilization.

[0028] Furthermore, the outer end of the sterilization chamber 1 is connected to a closed door 5 via a hinge, and the bottom of the sterilization chamber 1 is fixedly connected to a collection box 6. The inside of the collection box 6 is fixedly connected to a guide slope 7, and a guide pipe 8 is installed on one side of the collection box 6. The sterilization chamber 1 is sealed by the closed door 5 to reduce steam escape and ensure sterilization effect. After the moisture condenses, it is discharged through the holes of the rigid perforated plate 210 and the perforated pad 211, falls into the collection box 6, and is guided by the guide slope 7 to be discharged to the outside through the guide pipe 8.

[0029] Working principle: In use, firstly, the plastic cup is placed on the perforated pad 211, and the sterilization chamber 1 is sealed through the sealing door 5 to reduce steam escape and ensure sterilization effect. External high-pressure steam is input into the steam nozzle 3 through the steam conduit 4, and the steam nozzle 3 sprays steam to cover the plastic cup for sterilization. Secondly, during the flipping process, the second electric telescopic rod 215 and the third electric telescopic rod 217 extend and retract, causing the first push plate 216 and the second push plate 218 to form a clamping structure on the left and right sides of one end of the sliding bracket 209. This drives the sliding bracket 209 to move horizontally within the slide rail 208 to the clamping frame 212, aligning the two sets of sliding brackets 209 vertically. Thirdly, after the rotating shaft 203 disengages from the limit, the... The second motor 214 drives the adjusting screw 213 to rotate, causing the two sets of clamping frames 212 to move towards or away from each other along the slots of the rotating frame 207. This causes the perforated pad 211 to abut against the plastic cup and provide elastic clamping. The first motor 202 provides power to drive the rotating shaft 203 to rotate, causing the rotating frame 207 to rotate the clamped plastic cup. After flipping, the plastic cup is supported by another set of perforated pads 211 and continues to be exposed to the steam nozzle 3 for turning and sterilization. In the fourth step, the water condenses and is discharged through the holes of the rigid perforated plate 210 and the perforated pad 211, falling into the collection box 6 and being guided by the guide slope 7 to be discharged to the outside through the guide pipe 8. This completes the use of a sterilization device for the production of plastic yogurt cups.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
