Description

Technical Field

[0001] This utility model relates to the field of blueberry product processing technology, specifically a crusher for blueberry products. Background Technology

[0002] Blueberries have a sweet and sour taste and are rich in nutrients. They can prevent brain nerve aging, protect eyesight, strengthen the heart, fight cancer, soften blood vessels, and enhance the body's immune function. A crusher is often used in the production of blueberry juice.

[0003] A blueberry juice crusher (application number: 202022429840.3) has improved the crushing effect and working efficiency, and enhanced its practicality. However, the above-mentioned problems still exist. When producing blueberry juice, blueberries need to be fed into the crusher to crush them and separate the juice. However, during the crushing process, it is not convenient to perform secondary compression on the blueberry pulp, which easily leads to juice waste. Furthermore, when the crushing roller rotates, some blueberry pulp easily adheres to the outer wall of the crushing roller, which is not easy to scrape off, further increasing the waste. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in performing secondary compression on blueberry pulp, which easily leads to waste of juice, and the difficulty in scraping off the attached pulp, which further easily leads to waste. Therefore, this invention proposes a crusher for blueberry products.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a crusher for blueberry products, including a box body, a feed cylinder fixedly connected to the top inner wall of the box body, a shell fixedly connected to the upper side of one side of the box body, a straight block fixedly connected to one end of the inner wall of the box body, a filter screen with a gap fit on the outer wall of the straight block, crushing rollers rotatably connected to the inner walls of the front and rear ends of the feed cylinder through sealed bearings, and an extrusion structure provided on one side of the shell body.

[0007] Preferably, the extrusion structure includes a servo motor, the rear end of which is fixedly connected to a base and the rear end of the inner wall of the housing. A gear is fixedly connected to the output end of the servo motor, and a gear is meshed with the lower part of the gear. A threaded rod is fixedly connected to the inner wall of the gear. One side of the outer wall of the threaded rod is rotatably connected to the lower inner wall of the housing via a bearing. A square rod is clearance-fitted to the other side of the outer wall of the threaded rod. One side of the outer wall of the square rod is clearance-fitted to the upper inner wall of the housing. An extrusion plate is fixedly connected to one end of the square rod. The bottom of the extrusion plate is in contact with the top side of the filter screen. The front and rear sides of the extrusion plate are in contact with the inner wall of the housing. One side of the outer wall of the gear is rotatably connected to the upper inner wall of the housing via a bearing.

[0008] Preferably, the front end of the crushing roller is fixedly connected to the output end of the second servo motor, and the rear end of the second servo motor is fixedly connected to the front end of the feed cylinder.

[0009] Preferably, a curved block is attached to the bottom of the crushing roller, a curved rod is fixedly connected to the bottom of the curved block, and the top side of the curved rod is fixedly connected to the top side of the inner wall of the box.

[0010] Preferably, an inclined plate is fixedly connected to the lower part of the inner wall of the box.

[0011] Preferably, a cover plate is fitted to the inner wall of one end of the box with a clearance, and the inner wall of one side of the cover plate is threadedly connected to the inner wall of the upper side of the box by bolts.

[0012] The blueberry crusher proposed in this utility model has the following advantages: Through the cooperation of the housing, crushing rollers, servo motor II, shell, filter screen, feed cylinder, cover plate, and extrusion structure, the device can be used to drive the crushing rollers to rotate via servo motor II. The two crushing rollers crush the blueberries, thereby separating the juice from the pulp. The pulp falls on top of the filter screen, and the juice falls above the inclined plate. Servo motor I drives gear I to rotate, gear I drives gear II to rotate, and gear II drives the threaded rod to rotate. The inner wall on the upper side of the housing acts as a limit for the square rod, thereby driving the threaded rod to move the square rod to the right. The square rod drives the extrusion plate to move to the right. The extrusion plate and cover plate work together to achieve a second extrusion of the pulp, which facilitates the secondary extrusion of the blueberry pulp and avoids the waste of juice.

[0013] By combining the housing, feed cylinder, crushing roller, curved block, and curved rod, the device can be used so that when the curved block is in contact with the bottom of the crushing roller, the curved block scrapes off the pulp attached to the outer wall of the crushing roller when the crushing roller is rotated under force, which makes it easier to scrape off the attached pulp and further avoids waste.

The front end of the crushing roller 5 is fixedly connected to the output end of the servo motor 12, and the rear end of the servo motor 12 is fixedly connected to the front end of the feed cylinder 4. The model of the servo motor 12 is determined according to the actual use. A curved block 6 is attached to the bottom of the crushing roller 5. The curved block 6 facilitates scraping off the pulp attached to the outer wall of the crushing roller 5. A curved rod 7 is fixedly connected to the bottom of the curved block 6. The top side of the curved rod 7 is fixedly connected to the top side of the inner wall of the box 1. An inclined plate 3 is fixedly connected to the bottom of the inner wall of the box 1.

[0025] A cover plate 9 is fitted to the inner wall of one end of the box 1 with a gap. The inner wall of one side of the cover plate 9 is threadedly connected to the inner wall of the upper side of the box 1 by bolts. A rubber sleeve is fixedly connected to the inner wall of the upper side of the box 1. The rubber sleeve plays a sealing role. A compression structure 2 is provided on one side of the shell 8. The compression structure 2 facilitates secondary compression of the blueberry pulp, thereby avoiding waste of juice.

[0026] The extrusion structure 2 includes a servo motor 2a1. The base of the rear end of the servo motor 2a1 is fixedly connected to the rear end of the inner wall of the housing 8. The model of the servo motor 2a1 is determined according to the actual use. The output end of the servo motor 2a1 is fixedly connected to a gear 2a2. The lower part of the gear 2a2 is meshed with a gear 2a3. The inner wall of the gear 2a3 is fixedly connected to a threaded rod 2a4. One side of the outer wall of the threaded rod 2a4 is rotatably connected to the lower inner wall of one side of the housing 8 through a bearing.

[0027] A square rod 2a5 is fitted with a clearance fit on the other side of the outer wall of the threaded rod 2a4. One side of the outer wall of the square rod 2a5 is fitted with the upper inner wall of one side of the box 1 (the size of the opening between the box 1 and the square rod 2a5 can be designed according to actual needs). A rubber sleeve is fixedly connected to the upper inner wall of one side of the box 1. The rubber sleeve serves as a seal. One end of the square rod 2a5 is fixedly connected to a pressing plate 2a6. The bottom of the pressing plate 2a6 is attached to the top side of the filter screen 11. The front and rear sides of the pressing plate 2a6 are attached to the inner wall of the box 1. One side of the outer wall of the gear 2a2 is rotatably connected to the upper inner wall of one side of the housing 8 through a bearing, which facilitates secondary squeezing of the blueberry pulp and avoids waste of juice.

[0028] Working principle:

[0029] When crushing blueberries:

[0030] Blueberries are fed into the feed cylinder 4, and servo motor 12 starts working. Servo motor 12 drives the crushing roller 5 to rotate. The two crushing rollers 5 crush the blueberries (the two crushing rollers 5 rotate in opposite directions and synchronously inward), separating the juice from the pulp. The pulp falls on top of the filter screen 11, and the juice falls above the inclined plate 3. Servo motor 2a1 drives gear 2a2 to rotate, gear 2a2 drives gear 2a3 to rotate, and gear 2a3 drives the threaded rod 2a4 to rotate. The inner wall on the upper side of the box 1 limits the movement of the square rod 2a5, causing the threaded rod 2a4 to drive the square rod 2a5 to move to the right. The square rod 2a5 then drives the extrusion. Plate 2a6 moves to the right (the specific position of the extrusion plate 2a6 can be observed through the transparent inspection plate on the front side of the housing 1 so as to control the start, stop and forward / reverse rotation of the servo motor 2a1). The extrusion plate 2a6 and the cover plate 9 work together to extrude the pulp again. (The side wall of the housing 8 is provided with an inspection door, which is not shown in the figure. It can be used to inspect the inside of the housing 8 and clean the juice or pulp that flows into the housing 8 through the extrusion plate 2a6.) This causes the blueberry juice to fall on the top of the inclined plate 3. The valve on the lower side of the housing 1 is opened to discharge the blueberry juice. At the same time, the curved block 6 is attached to the bottom of the crushing roller 5, which can scrape off the attached pulp to avoid waste.

[0031] When it is necessary to drain the pulp:

[0032] Rotate the bolt to remove it from the inner wall of the housing 1 and the cover plate 9. A rubber sleeve is provided at the contact point between the housing 1 and the cover plate 9, which provides a seal before the cover plate 9 is removed. Move the cover plate 9 to the right to remove it. Servo motor 2a1 starts working, driving gear 2a2 to rotate. Gear 2a2 drives gear 2a3 to rotate, which in turn drives the threaded rod 2a4 to rotate. The inner wall on the upper side of the housing 1 acts as a limit for the parallel rod 2a5, thereby causing the threaded rod 2a4 to rotate. The square rod 2a5 moves to the right, which in turn moves the extrusion plate 2a6 to the right, thus pushing the pulp out to the right. The servo motor 2a1 drives the gear 2a2 to rotate in the opposite direction, which in turn drives the gear 2a3 to rotate in the opposite direction. The gear 2a3 drives the threaded rod 2a4 to rotate in the opposite direction. The inner wall on the upper side of the box 1 limits the square rod 2a5, which in turn drives the threaded rod 2a4 to move the square rod 2a5 to the left. The square rod 2a5 then drives the extrusion plate 2a6 to move to the left, thus resetting the extrusion plate 2a6.

[0033] Example 2:

[0034] See attached document Figure 1-6In this embodiment, a crusher for blueberry products is provided, wherein the extrusion structure 2 may further include a horizontal block 2b1. One end of the horizontal block 2b1 is fixedly connected to the lower side of the inner wall of the housing 1. An insert rod 2b3 is fitted into the inner wall of the horizontal block 2b1 with a gap. The upper side of the outer wall of the insert rod 2b3 is fitted into the inner wall of the bottom side of the filter screen 11 and the bottom groove of the straight block 10 with a gap. A spring 2b2 is fitted into the lower side of the outer wall of the insert rod 2b3 with a gap. The spring 2b3 provides an upward force to the insert rod 2b3. The upper and lower ends of the spring 2b2 are fixedly connected to the bottom of the horizontal block 2b1 and the lower side of the outer wall of the insert rod 2b3, respectively.

[0035] Working principle:

[0036] Pulling down the insert rod 2b3 compresses the spring 2b2. At the same time, the insert rod 2b3 moves out from the inner wall of the straight block 10 and the filter screen 11, moves the filter screen 11 forward, and moves it out from the outer wall of the straight block 10, thereby realizing the disassembly of the filter screen 11, which makes it convenient for staff to maintain or replace the filter screen 11.

[0037] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
