Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, and in particular to a pear juice pre-pressing and residue secondary crushing device. Background Technology

[0002] Pears, a common fruit, are rich in water, vitamins, and various minerals, making them a popular choice. Pear juice not only has a sweet and refreshing taste but also possesses medicinal properties such as quenching thirst, relieving dryness, clearing heat, and resolving phlegm. Therefore, pear juice and related beverages have maintained a stable market demand. Existing juicing equipment typically uses manual pressing, general-purpose fruit blenders, or a single unidirectional extrusion or centrifugal separation principle. Traditional juicing devices usually only perform one extraction, resulting in a large amount of juice remaining in the pear pulp that is not fully extracted, thus wasting raw materials.

[0003] Therefore, those skilled in the art have provided a pear juice pre-pressing and residue secondary crushing device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a pear juice pre-pressing and residue secondary crushing device. The device uses a first servo motor and rotating rollers for initial juicing, extracting most of the juice. The residue and remaining liquid then enter a connecting cylinder via a stirring drum. Subsequently, a second servo motor drives an auger to feed the mixture into a crushing drum, where a cylinder drives a pressing plate for powerful crushing, completing the secondary juicing process. This increases the juice yield, reduces raw material waste, and improves production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A pear juice pre-pressing and residue secondary crushing device includes a juicing cylinder and a crushing cylinder. The inner wall of the juicing cylinder is provided with a pre-pressing mechanism, and the inner wall of the crushing cylinder is provided with a crushing mechanism. The pre-pressing mechanism includes a top plate, the lower end of which is fixedly connected to the upper end of the juicing cylinder. A stirring cylinder is fixedly connected to the lower end of the top plate. The outer wall of the stirring cylinder is evenly provided with water outlets. A groove is provided on the inner wall of the top plate. A rotating column is rotatably connected to the other side of the bottom surface of the groove. A first gear is fixedly connected to the outer wall of the rotating column. A fixing block is fixedly connected to the lower end of the inner wall of the stirring cylinder. A rotating roller is rotatably connected to the upper end of the fixing block. A second gear is fixedly connected to the outer wall of the upper end of the rotating roller. A first protective box is fixedly connected to the other side of the middle of the upper part of the top plate. A first servo motor is fixedly connected to the top surface of the first protective box. The above technical solution involves starting the first servo motor, which drives the first gear of the rotating column to rotate. Through gear transmission, the first gear drives the second gear and the rotating roller to rotate synchronously. The rotating roller contacts the pear raw material, performing preliminary squeezing and agitation on the pear to extract most of the juice.

[0006] Furthermore, a connecting cylinder is fixedly connected to one side of the lower end of the juicing cylinder, a second servo motor is provided on one side of the inner wall of the connecting cylinder, an auger is fixedly connected to the output end of the second servo motor, the other side of the connecting cylinder is connected through to the upper part of one side of the crushing cylinder, a second protective box is fixedly connected to the middle of the upper end of the outer wall of the crushing cylinder, a cylinder is fixedly connected to the top surface of the second protective box, a crushing plate is fixedly connected to the output end of the cylinder, and multiple discharge ports are opened on the bottom surface of the crushing cylinder. Through the above technical solution, the second servo motor is started, which drives the auger to rotate. Its spiral structure pushes the pear pulp from the connecting cylinder forward, and transports the residue and some juice into the crushing cylinder. Then, the cylinder is started to drive the crushing plate to rise and fall, further releasing the juice remaining in it, realizing secondary juicing, thereby improving the overall juice yield.

[0007] Furthermore, an electromagnetic control valve is provided at the lower end of the juicing cylinder, and a feed inlet is provided on one side of the middle part of the upper end of the top plate; The above technical solution controls the flow of juice, automatically opens and closes the juice outlet, facilitates juice collection, avoids dripping, and makes it easy for operators to put pear pieces into the mixing drum.

[0008] Furthermore, a storage bin is provided at the lower end of the crushing cylinder; The above technical solution enables the immediate collection and storage of juice, improving the continuity and automation of the production process.

[0009] Furthermore, the first gear meshes with the second gear; The above technical solution ensures that the power of the first servo motor can be accurately and reliably transmitted to the rotating roller through gear transmission.

[0010] Furthermore, the upper end of the rotating column penetrates through the top plate to the outside of the top plate and is fixedly connected to the output end of the first servo motor, and the lower end of the rotating roller penetrates through the top plate to the outside of the top plate; Through the above technical solution, the rotating column is connected to the first servo motor, ensuring that the rotational power output by the first servo motor is directly and firmly transmitted to the rotating column, thereby driving the first gear.

[0011] Furthermore, the other side of the connecting cylinder extends through the juicing cylinder to the outside of the juicing cylinder, and the lower end of the stirring cylinder is connected to the connecting cylinder in a through-hole connection; The above technical solution enables the residue and some juice produced after the initial juicing to be smoothly discharged from the bottom of the mixing drum through the connecting drum and guided into the crushing drum, ensuring the directional flow of materials and preventing blockage.

[0012] Furthermore, the cylinder output end extends through the crushing cylinder into its interior; The above technical solution enables the cylinder to directly drive the crushing plate to move up and down inside the crushing cylinder, thus compressing the pear pulp.

[0013] This utility model has the following beneficial effects: 1. This utility model proposes a pear juice pre-pressing and residue secondary crushing device. The device uses a first servo motor and a rotating roller to pre-press the pear juice, extracting most of the juice. The residue and some juice enter the connecting cylinder through the lower end of the stirring cylinder. Then, through the cooperation of a second servo motor and an auger, the residue and some juice are fed into the crushing cylinder. In the crushing cylinder, a cylinder drives a pressing plate to forcefully squeeze and crush the pear residue, completing the secondary juicing. This design not only improves the overall juice yield and reduces raw material waste, but also improves production efficiency, ultimately achieving increased economic benefits.
