Abstract
Description
Technical Field
[0001] This application relates to the field of canned food production equipment technology, and in particular to a quantitative filling device for canned citrus fruit production. Background Technology
[0002] The raw materials for canned fruit are generally fruits, including yellow peaches, apples, lychees, pears, and hawthorns. Products mainly include canned yellow peaches, canned pears, canned jackfruit, and canned oranges. During the processing of canned fruit, sugar syrup needs to be added to the packaging bottles. Therefore, a precise amount of sugar syrup needs to be injected into the bottles using filling equipment, and the amount added needs to be adjusted according to the type and size of the canned fruit.
[0003] A search revealed a patent document with authorization announcement number CN222388402U, which discloses a quantitative device for fruit canning production. The device includes a filling tank with an inlet pipe connected to its top wall, extending to the bottom of the tank's inner cavity. A solenoid valve is mounted on the inlet pipe. A filling pipe with a second solenoid valve is connected to the bottom wall of the tank. A controller is located outside the tank. The device injects sugar syrup into the inner cavity of the filling tank through the inlet pipe, causing a floating plate to rise and touch a contact sensor on the top of a connecting rod. This triggers the sensor, at which point the processor closes the first solenoid valve and opens the second solenoid valve to perform quantitative filling. Furthermore, the height of the contact sensor can be adjusted by rotating a threaded rod with a handwheel, limiting the maximum height of the connecting rod. Users can adjust the maximum amount of sugar syrup that can be stored inside the filling tank according to the needs of different packaging bottles.
[0004] In practical use, it was found that the existing device cannot properly align the canning jars when filling them with sugar water, which easily leads to misalignment between the filling tube and the jar opening, resulting in spillage of the sugar water and affecting the filling quality. Therefore, we have proposed a quantitative filling device for citrus canning to solve the above problems. Utility Model Content

[0036] Specifically, the conveying mechanism includes two conveying rollers 102 and a conveyor belt 103. Two conveying rollers 102 are provided inside the base 1. One conveying roller 102 is rotatably connected to the inner wall of the front side and the inner wall of the rear side of the base 1 on both sides. The other conveying roller 102 is fixedly sleeved on the output shaft of the motor 101. The same conveyor belt 103 is driven and sleeved on the two conveying rollers 102.
[0037] Specifically, the jacking mechanism includes a rotating shaft 201 and a cam 202. The rotating shaft 201 is rotatably mounted on the inner wall of the left side of the function box 2. The cam 202 is fixedly sleeved on the rotating shaft 201. A gear mechanism is provided between the rotating shaft 201 and the output shaft of the motor 101.
[0038] Specifically, the gear mechanism includes two bevel gears 7. The right end of the rotating shaft 201 and the output shaft of the motor 101 are both fixedly fitted with bevel gears 7. The bevel gears 7 are located inside the function box 2, and the two bevel gears 7 mesh with each other.
[0039] Specifically, the alignment mechanism includes a push plate 203, a push rod 204, and an alignment plate 205. The push plate 203 is installed inside the function box 2 and is located behind the rotating shaft 201. The cam 202 is adapted to the push plate 203. The push rod 204 is fixedly installed on the rear side of the push plate 203. The alignment plate 205 is installed inside the base 1 and is located above the conveyor belt 103. The front side of the alignment plate 205 is fixedly connected to the rear end of the push rod 204.
[0040] Specifically, a spring 8 is fixedly installed on the rear side of the push plate 203. The spring 8 is located below the push rod 204, and the rear end of the push rod 204 is fixedly connected to the inner wall of the rear side of the function box 2.
[0041] Specifically, the quantitative filling mechanism includes a filling tube 302 and a metering pump 304. The filling tube 302 is provided at the bottom of the filling seat 301, and the metering pump 304 is provided at the top of the filling seat 301.
[0042] Specifically, the sensing mechanism includes a controller 303 and an infrared sensor 6. The controller 303 is located on the left side of the filling base 301, and the infrared sensor 6 is located at the bottom of the filling base 301.

[0044] Specifically, teeth are provided on both the outer side of the conveyor roller 102 and the inner side of the conveyor belt 103.
[0045] In this application, during operation, after the motor 101 starts, the power is transmitted to the conveyor roller 102 connected to it, which drives the conveyor belt 103 to run stably.

After filling is completed, the motor 101 restarts according to the preset time.
[0047] Meanwhile, the bevel gear 7 on the output shaft of motor 101 meshes with the bevel gear 7 on the right end of rotating shaft 201, which drives rotating shaft 201 to rotate. The cam 202 fixedly sleeved on rotating shaft 201 rotates accordingly. When the protruding part of cam 202 contacts push plate 203, it pushes push plate 203 to move backward and compresses spring 8. Push plate 203 drives aligning plate 205 to move towards canning bottle 5 through push rod 204. This enables aligning plate 205 to push canning bottle 5 backward, aligning the mouth of canning bottle 5 with filling tube 302, ensuring that canning bottle 5 remains upright during filling, preventing soup from overflowing, and improving filling accuracy and efficiency. When the protruding part of cam 202 leaves push plate 203, spring 8 returns to its original state, pushing push plate 203 back to its initial position, preparing for the next aligning action.
[0048] The entire device, through the close coordination of mechanical linkage and electrical control, realizes a series of functions such as automatic conveying, precise positioning, quantitative filling and timely alignment of canning bottles 5, which effectively improves the automation level and production efficiency of citrus canning production, while ensuring the stability and consistency of product quality, reducing labor costs and production errors, and meeting the needs of large-scale industrial production.
