Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology for juicing equipment, specifically a new type of cutting tool combination for thin-skinned juicing equipment. Background Technology

[0002] In modern juice production equipment, efficient and precise separation of peel and pulp is key to improving juice quality and yield. Traditional juicing equipment typically uses simple pressing or rotary cutting methods, which face the following problems when processing thin-skinned fruits: during the pressing process, the peel often mixes with the pulp, leading to a decrease in juice purity; at the same time, the peel is not thoroughly processed, affecting sorting efficiency. Existing equipment has poor adaptability to fruits of different sizes, especially thin-skinned fruits. Due to the difficulty in adjusting the blade position and pressing mechanism, it cannot meet the diverse fruit processing needs. The applicant's earlier Chinese patent application No. 202320958267.6 describes an adjustable blade mechanism in an oval-shaped fruit peeling and juicing device, which allows for adjustment of the horizontal blade to achieve cleaner and more thorough separation of fruit pulp and peel. However, the vertical blade structure still uses the original fixed structure, which has poor adaptability to fruits of different sizes. In response to the above problems, some technical solutions have attempted to improve the situation by using adjustable blade assemblies. However, due to the complexity of the structure and the inconvenience of adjustment, these improvements have not completely solved the above problems. Therefore, a new blade combination for a thin-skinned juicing device is proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new type of blade combination for thin-skin juicing equipment. Through the innovative W-shaped blade layout and high-precision adjustment mechanism, it realizes efficient juice extraction and precise separation of peel and pulp, significantly improving the juice yield and juice purity, and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel blade assembly for a thin-skin juicing device, comprising a housing, a pressing roller assembly, a scraper assembly, a horizontal blade assembly, and a vertical blade. The scraper assembly, horizontal blade assembly, and vertical blade are disposed within the housing and arranged in a W-shape to form a W-shaped blade. The vertical blade is positioned at the feed inlet in the middle of the pressing roller assembly, corresponding to the feed hopper at the upper end of the housing.

[0005] Furthermore, a filter screen is installed below the press roller assembly, and the filter screen is mounted on a filter screen frame.

[0006] Furthermore, the vertical blade is fixed to the filter screen frame, and a locking nut is provided between the filter screen frame and the housing.

[0007] Furthermore, a vertical blade adjustment mechanism is provided below the vertical blade. The vertical blade adjustment mechanism includes an adjustment shaft, a meshing bevel gear, a worm gear, a lifting nut, a worm, a connecting shaft, and a lead screw with a shaft. The adjustment shaft is connected to the worm through the meshing bevel gear. The worms are connected to each other through the connecting shaft. The worm meshes with the worm gear. The worm gear is mounted on the lead screw with a shaft. The lifting nut on the lead screw with a shaft is fixed to the filter screen frame.

[0008] Furthermore, the scraper is provided with an adjustment elongated hole, and the scraper is fixed to the scraper mounting seat by the cooperation of the adjustment elongated hole and bolts.

Therefore, they should not be construed as limitations on this utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a novel blade assembly for a thin-skinned juicing device, comprising a housing 13, a pressing roller assembly 11, a scraper assembly 10, a horizontal blade assembly 14, and a vertical blade 8. The scraper assembly 10, the horizontal blade assembly 14, and the vertical blade 8 are disposed in the housing 13 and arranged in a W-shape to form a W-shaped blade. The vertical blade 8 is located at the feed inlet in the middle of the pressing roller assembly 11. The function of the vertical blade 8 is to cut the raw material entering the device in half, making it easier for the pressing roller assembly 11 to press and improve the juice yield of the raw material. After being pressed by the pressing roller assembly 11, the juice is filtered through the filter screen 7 under the pressing roller assembly 11 and then enters the fruit juice processing plant. The juice collection system features an adjustable vertical blade 8 to accommodate fruits of different sizes. The vertical blade 8 corresponds to the feed hopper 12 at the upper end of the housing 13. The horizontal blade assembly 14 is located on both sides of the lower part of the pressing roller assembly 11, with the horizontal blades of the assembly 14 tangent to the pressing roller assembly 11. The horizontal blade assembly 14 is used for secondary cutting of the peel and pulp, and its height and front-back position can be adjusted through an adjustable mechanism to improve the separation efficiency of the peel and pulp. The horizontal blade assembly 14 consists of an adjusting handle, a rotating fixed plate, an indexing plate, a cam device, a cam rotation passive device, a horizontal blade, a horizontal blade fixing plate, an adjusting hole sleeve, a locking bolt, a blade holder support shaft, a passive shaft, a drive shaft, and a return spring.

[0020] The applicant has already applied for a patent for this cross-blade assembly, Chinese patent application number 202320958267.6, which describes an adjustable cutting mechanism for an elliptical fruit peeling and juicing device. The specific composition and structure are not described in detail here. The principle of cross-blade adjustment is as follows: rotating the adjustment handle causes the cam device fixed on the rotating shaft to rotate. The passive rotating device of the cam moves along the outer contour of the cam device under the action of the return spring, thereby driving the cross-blade to rotate around the blade holder support shaft with the cross-blade fixing plate, so as to realize the height and front and back adjustment of the cross-blade. Then, loosening the locking bolt on the adjustment hole sleeve and adjusting the position of the locking hole sleeve can adjust the position of the baffle between the peel hopper and the pulp hopper, ensuring that the peel and pulp accurately enter their respective hoppers and ensuring the cleanliness of the pulp. In addition, the feed rate can be clearly understood through the scale value on the indexing plate, so as to achieve precise separation of fruit pulp and peel. After the cross blade is adjusted to the appropriate distance, the adjustment handle is locked on the indexing plate by rotating the fixing mechanism to prevent the cam device from rotating. Then, the locking bolt and the tightening bolt on the adjusting hole sleeve are tightened to prevent the cross blade and the hopper partition from moving. The realization of this function can ensure the precise separation of peel and pulp, and avoid the waste of pulp due to the peel being separated too thickly. The scraper assembly 10 is set on the upper part of both sides of the pressing roller group 11. The scraper assembly 10 includes a scraper 17 and a scraper fixing seat 18. The scraper 17 is fixed on the scraper fixing seat 18.

[0021] A filter screen 7 is installed below the press roller assembly 11. The filter screen 7 is mounted on the filter screen frame 16 and is used to filter the juice, thereby separating the peel from the juice.

[0022] The vertical blade 8 is fixed on the filter screen frame 16. A locking nut 9 is provided between the filter screen frame 16 and the housing 13. The housing 13 has an elongated hole for adjusting the filter screen frame 16 up and down. When the vertical blade 8 is adjusted to the appropriate position, the locking nut 9 is locked to prevent the vertical blade 8 from moving up and down.

[0023] Below the vertical blade 8 is a vertical blade adjustment mechanism, which includes an adjusting shaft 1, a meshing bevel gear 2, a worm gear 3, a lifting nut 4, a worm 5, a connecting shaft 6, and a lead screw 15 with a shaft. The adjusting shaft 1 is connected to the worm 5 through the meshing bevel gear 2, and the worms 5 are connected to each other through the connecting shaft 6 to realize the transmission of power between the worms 5. The meshing bevel gear 2 realizes the direction of power. The worm 5 meshes with the worm gear 3, which is mounted on the lead screw 15 with a shaft. The lifting nut 4 on the lead screw 15 with a shaft is fixed to the filter screen frame 16.

[0024] The adjustment principle involves rotating the adjusting shaft 1, which drives the two pairs of meshing bevel gears 2 at both ends to rotate. This, in turn, drives the worm gear 5 to rotate via the meshing bevel gears 2. The worm gear 3, which meshes with the worm gear 5, rotates via the connecting shaft 6. The worm gear 3 then drives the lead screw 15 with a shaft to rotate. When the lead screw 15 with a shaft rotates, it drives the filter screen frame 16 to move up and down via the lifting nut 4. The vertical blade 8 is fixed on the filter screen frame 16, thus realizing the up and down movement of the vertical blade 8. This function ensures that raw materials of different sizes can be cut, thereby better realizing the pressing function, increasing the juice yield, and also preparing for the next step of separating the pulp and peel.

[0025] The height of the vertical blade 8 is not limited to the method described above; any implementation based on this function is within the scope of its claims.

[0026] The scraper 17 is provided with an adjustment elongated hole 19. The scraper 17 is fixed to the scraper fixing seat 18 through the cooperation of the adjustment elongated hole 19 and bolts. The front and rear position can be adjusted by adjusting the elongated hole 19 to thoroughly remove the peel and prevent the peel from entering the pulp collection system, thereby improving the juice yield and sorting rate. The front and rear adjustment of the scraper 17 is not limited to the above-mentioned adjustment. Any implementation based on this function is within the scope of its claims.

[0027] The foregoing has shown and described the basic principles, main features and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this utility model as claimed.
