Description

Technical Field

[0001] This utility model relates to the field of pet food processing technology, specifically to a nozzle for spraying oil onto canned food. Background Technology

[0002] Pet food processing refers to the process of transforming animal or plant-based raw materials into specialized food that meets the nutritional needs, palatability, and safety standards of pets through raw material processing, formula design, and technological processes. It targets pets such as dogs, cats, fish, and birds, and product forms include dry food (extruded food), wet food (canned food, meat puree), semi-moist food, treats, and functional supplements. The main functions of pet food include:

[0003] Based on the pet's breed, age, physiological stage (e.g., puppyhood, pregnancy), and health needs (e.g., weight loss, joint care), we add nutrients such as protein, fat, vitamins, and minerals to ensure nutritional balance. Processes like puffing, steaming, and baking improve palatability while simultaneously destroying anti-nutritional factors (e.g., phytic acid) in the raw materials, increasing digestibility and absorption. High-temperature sterilization (e.g., 121℃ for 30 minutes for canned food), vacuum packaging, and the addition of natural preservatives (e.g., vitamin E) inhibit microbial growth and extend shelf life to 1-3 years. We rigorously test for heavy metals, aflatoxin, Salmonella, and other harmful substances to ensure compliance with international standards. We develop products for specific needs, such as joint protection (with added glucosamine), coat care (containing fish oil), and weight management (low-fat, high-fiber). Formulas are customized based on the pet's allergy history (e.g., grain allergy) or special diet (e.g., raw meat and bone diet). Dry food is easy to store and allows for measured feeding, wet food meets the pet's hydration needs, and treats are used for training and rewards.

[0004] However, in actual use, existing pet food canning processes often employ fixed nozzles or manual spraying for grease coating. When using fixed nozzles, the nozzle position is relatively fixed, and grease tends to accumulate at the bottom of the can, leading to localized excessive grease levels and uneven grease distribution. When using manual spraying, the efficiency is low, and it is difficult to ensure precise control of the coating amount. Utility Model Content

[0005] The purpose of this utility model is to provide a nozzle for spraying oil onto canned food, in order to solve the problems mentioned in the background art, where oil spraying in existing pet food canning processes mostly uses fixed nozzles or manual spraying. When using fixed nozzles, the nozzle position is relatively fixed, and oil tends to accumulate at the bottom of the can, resulting in local oil exceeding the standard and uneven oil distribution. When using manual spraying, the manual spraying efficiency is low, and it is difficult to ensure precise control of the spraying amount.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a processing table, with support plates fixedly installed on both sides of the processing table. A support frame is fixedly installed on the outer side of the support plates. A drive motor is fixedly installed at the rear end of the support frame. An adjusting gear is fixedly installed on the upper transmission shaft of the drive motor. An adjusting gear ring is meshed with the front end of the adjusting gear. A rotating table is fixedly installed in the middle of the adjusting gear ring. A vertical electric telescopic rod is fixedly installed through the middle of the rotating table. A lifting plate is fixedly installed on the lower telescopic part of the vertical electric telescopic rod. Vertical limiting slide rods are fixedly installed on both sides of the upper end of the lifting plate. An extension frame is fixedly installed at the lower end of the extension frame via a rotating shaft. An adjusting shaft is rotatably connected to the lower end of the adjusting shaft via a rotating shaft. A nozzle for spraying oil onto the inner wall of the can is fixedly installed on the outer curved surface of the lower end of the adjusting shaft. A fastening ring for locking and tightening the adjusting shaft is threadedly connected to the outer curved surface of the side end of the adjusting shaft.

[0007] Preferably, a power control box is fixedly installed on the front side of the upper end of the processing table, and a conveyor belt for conveying canned goods is fixedly installed in the middle of the upper end of the processing table.

[0008] Preferably, there are two support plates, symmetrically distributed on both sides of the processing table. A horizontal electric telescopic rod is fixedly installed through the middle of the upper end of each support plate, and limit sliding tubes are fixedly installed through the two sides of the upper end of each support plate. A limit plate for limiting the position of the can is fixedly installed on the inner telescopic part of the horizontal electric telescopic rod.

[0009] Preferably, the front and rear ends of the limiting plate extend outward, and horizontal limiting slide rods are fixedly installed on the outer sides of both ends of the limiting plate, and the horizontal limiting slide rods are movably connected to the inner wall of the limiting slide tube.

[0010] Preferably, the rotating platform is rotatably connected to the upper middle part of the support frame via a rotating shaft, and the upper end of the vertical limiting slide rod is movably connected to both sides of the rotating platform.

[0011] Preferably, the front end of the lifting plate is fixedly supported with an identification camera for identifying cans, and a knob is fixedly installed on the side end of the adjustment shaft, with an external thread on the outer curved surface of the side end of the adjustment shaft.

[0012] Preferably, an oil storage tank is fixedly installed on the rear side of the upper end of the support frame, and an oil injection pump is fixedly connected to the bottom of the oil storage tank. The lower outlet of the oil injection pump is connected to the nozzle through a connecting hose.

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

[0014] This invention allows the canned food to be conveyed backward in a straight line. A recognition camera identifies the can, and when it reaches the lower end of the lifting platform, the conveyor belt is shut off. When the conveyor belt is shut off, a vertical electric telescopic rod is activated. This activation causes the lifting platform to move downward in a straight line, which in turn causes the extension frame to move downward in a straight line. Simultaneously, the extension frame moves downward in a straight line, causing the nozzle to extend downward into the can. When the nozzle extends downward into the can, an oil injection pump is activated. When the oil injection pump is activated, the oil from the storage tank is delivered to the nozzle and sprayed into the can, thus facilitating the spraying of oil into the interior of the pet food can.

[0015] This invention also features a mechanism where, when the drive motor is turned on, it drives the adjusting gear to rotate. This rotation of the adjusting gear meshes with and drives the adjusting gear ring to rotate. The rotation of the adjusting gear ring, in turn, drives the rotating platform to rotate. The rotation of the rotating platform, in turn, drives the vertical electric telescopic rod to rotate. The rotation of the vertical electric telescopic rod, in turn, drives the lifting plate to rotate. The rotation of the lifting plate, in turn, drives the extension frame to rotate. Simultaneously, the extension frame rotates and swings, allowing the nozzle to oscillate and rotate, ensuring that the oil is evenly sprayed into the can. Attached Figure Description

[0021] Please see Figure 1-3 This utility model provides a technical solution for a nozzle for spraying oil onto canned food: it includes a processing table 1, and a power control box is fixedly installed on the front side of the upper end of the processing table 1. A conveyor belt 2 for conveying canned food is fixedly installed in the middle of the upper end of the processing table 1. Support plates 3 are fixedly installed on both sides of the processing table 1, and there are two support plates 3, which are symmetrically distributed on both sides of the processing table 1. A horizontal electric telescopic rod 4 is fixedly installed through the middle of the upper end of the support plate 3. A limiting slide tube 5 is fixedly installed through the upper ends of both sides of the support plate 3. A limiting plate 6 for limiting the canned food is fixedly installed on the telescopic part inside the horizontal electric telescopic rod 4. The front and rear ends of the limiting plate 6 extend outward. A horizontal limiting slide rod 8 is fixedly installed on the outer side of both ends of the limiting plate 6. The horizontal limiting slide rod 8 is movably connected to the inner wall of the limiting slide tube 5, so that the limiting slide tube 5 and the horizontal limiting slide rod 8 can limit the horizontal linear movement of the limiting plate 6.

[0022] A support frame 9 is fixedly installed on the outer side of the support plate 3. A drive motor 10 is fixedly installed on the inner top rear end of the support frame 9. An adjusting gear 11 is fixedly installed on the upper transmission shaft of the drive motor 10. An adjusting gear ring 12 is meshed with the front end of the adjusting gear 11. A rotating platform 13 is fixedly installed in the middle of the adjusting gear ring 12. The rotating platform 13 is rotatably connected to the upper middle of the support frame 9 through a rotating shaft. A vertical electric telescopic rod 14 is fixedly installed through the middle of the rotating platform 13. A lifting plate 15 is fixedly installed on the lower telescopic part of the vertical electric telescopic rod 14. Vertical limiting slide rods 16 are fixedly installed on both sides of the upper end of the lifting plate 15. The upper ends of the vertical limiting slide rods 16 are movably connected to both sides of the rotating platform 13, so that the lifting plate 15 is controlled by the vertical limiting slide rods 16. 5. Vertical linear movement limit is performed. A recognition camera for identifying cans is fixedly installed at the front end of the lifting plate 15. An extension frame 17 is fixedly installed at the lower end of the lifting plate 15. An adjustment shaft 18 is rotatably connected to the lower end of the extension frame 17 via a rotating shaft. A nozzle 19 for spraying oil onto the inner wall of the can is fixedly installed on the outer curved surface of the lower end of the adjustment shaft 18. A knob is fixedly installed on the side end of the adjustment shaft 18. An external thread is opened on the outer curved surface of the side end of the adjustment shaft 18. A fastening ring 7 for locking and tightening the adjustment shaft 18 is connected to the thread on the outer curved surface of the side end of the adjustment shaft 18. An oil storage tank 20 is fixedly installed on the rear side of the upper end of the support frame 9. An oil injection pump 21 is fixedly connected to the bottom of the oil storage tank 20, and the lower outlet of the oil injection pump 21 is connected to the nozzle 19 via a connecting hose.

[0023] Working principle: In use, this utility model uses a conveyor belt 2 to transport canned goods. When the cans are being transported, a limiting plate 6 centers and limits the cans, ensuring that the cans are transported in a straight line backward. At the same time, the horizontal electric telescopic rod 4 is opened by control. When the horizontal electric telescopic rod 4 is opened, it will drive the limiting plate 6 to move outward or inward in a straight line. When the limiting plate 6 moves outward or inward in a straight line, it will adjust the limiting distance of the cans, thereby facilitating the straight backward transport of cans of different sizes.

[0024] As the cans are conveyed backward in a straight line, the recognition camera identifies the cans. When the cans reach the lower end of the lifting plate 15, the conveyor belt 2 is shut off by control. When the conveyor belt 2 is shut off, the vertical electric telescopic rod 14 is opened by control. When the vertical electric telescopic rod 14 is opened, it will drive the lifting plate 15 to move downward in a straight line. When the lifting plate 15 moves downward in a straight line, it will drive the extension frame 17 to move downward in a straight line. When the extension frame 17 moves downward in a straight line, it will simultaneously drive the nozzle 19 to extend downward into the can. When the nozzle 19 extends downward into the can, the oil injection pump 21 is turned on by control. When the oil injection pump 21 is turned on, it will transport the oil inside the oil storage tank 20 to the nozzle 19 and spray it into the can through the nozzle 19, thereby facilitating the spraying of oil into the pet food can.

[0025] Simultaneously, by controlling the start of the drive motor 10, when the drive motor 10 is turned on, it drives the adjusting gear 11 to rotate. When the adjusting gear 11 rotates, it meshes and drives the adjusting gear ring 12 to rotate. When the adjusting gear ring 12 rotates, it drives the rotating table 13 to rotate. When the rotating table 13 rotates, it drives the vertical electric telescopic rod 14 to rotate. When the vertical electric telescopic rod 14 rotates, it drives the lifting plate 15 to rotate. When the lifting plate 15 rotates, it drives the extension frame 17 to rotate. When the extension frame 17 rotates, it synchronously drives the nozzle 19 to swing and rotate, thereby achieving oil spraying inside the pet food can while facilitating swinging and rotating oil spraying, so that the oil is evenly sprayed into the can.
