Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, specifically to a continuous slicing device for dried hawthorn that prevents sticking. Background Technology

[0002] Hawthorn is rich in pectin, organic acids, and soluble sugars. Even after fresh fruit is dehydrated to make dried hawthorn, a large amount of sticky gelatinous components remain inside. It is a core raw material for making candied fruit, traditional Chinese medicine slices, tea, and compound ingredients. In industrial production, block-shaped dried hawthorn needs to be sliced ​​in a standardized manner. The uniformity of slice thickness, production continuity, and ease of equipment operation and maintenance directly determine the quality and processing capacity of the deep-processed hawthorn products. Therefore, continuous slicing equipment is an indispensable core equipment in the deep-processing production line of hawthorn.

[0003] Existing slicing devices generally use one-piece smooth blades without an automatic blade cleaning mechanism. During slicing, the blade edge and surface continuously adhere to pectin and sugary substances leached from hawthorn. As processing time increases, these sticky materials accumulate and form scale, increasing cutting resistance and causing uneven slice thickness, rough edges, and a surge in fragmentation, significantly reducing the yield of qualified dried hawthorn slices. Furthermore, existing hawthorn slicing devices often use bolt-locked or welded mounting methods to assemble the slicing blades inside the blade holder, resulting in a fixed assembly structure and lacking quick disassembly and replacement capabilities. Long-term, high-frequency cutting easily causes chipping, rolling, and dulling of the slicing blade edge, leading to a high blade wear rate. Replacing the slicing blade requires disassembling the external protective cover and multiple transmission components, using wrenches, screwdrivers, and other tools for reassembly and alignment, resulting in low efficiency. Summary of the Invention

This significantly reduces equipment downtime losses and lowers equipment maintenance costs. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] refer to Figures 1-7 The illustrated continuous slicing device for preventing sticking of dried hawthorn includes a device frame 1 and a slicing blade 11. The device frame 1 is equipped with a cleaning component and a quick-release component. The cleaning component is used to automatically clean the material adhering to the surface of the slicing blade 11, and the quick-release component is used to quickly replace the slicing blade 11. A specific embodiment is shown below:

[0030] Example 1

[0031] Two rollers 12 are rotatably connected inside the device frame 1. The outer walls of the two rollers 12 are fitted with a conveyor belt 3. The slicing blade 11 is fixedly connected to the insertion tube 17. Fixed plates 5 are fixedly connected to both sides of the device frame 1. A guide tube 6 is fixedly connected to the upper surface of the fixed plate 5. A spline rod 7 is slidably connected inside the guide tube 6. The spline rod 7 passes through the fixed plate 5 and extends to the area below the fixed plate 5. A mounting frame 13 is fixedly connected to the lower surface of the device frame 1. A drive shaft 14 is rotatably connected inside the mounting frame 13. Cam blocks 9 are fixedly connected to both ends of the drive shaft 14. A hinge seat 18 is fixedly connected to one end of the spline rod 7 near the cam block 9. A hinge plate 10 is rotatably connected inside the hinge seat 18, and the hinge plate 10 is rotatably connected to the cam block 9. A connecting plate 2 is fixedly connected to the top ends of the two spline rods 7.

[0032] The external drive motor of the device drives the drive shaft 14 to rotate at a uniform speed, which in turn drives the cam blocks 9 at both ends to rotate in a circular motion. The hinge plate 10 is pushed and pulled to swing based on the cam contour trajectory. The hinge plate 10 pulls the spline rod 7 to make vertical reciprocating linear motion along the guide tube 6 through the hinge seat 18. The spline rod 7 and the spline limiting structure of the guide tube 6 are used to eliminate the horizontal torque generated by the slicing operation and prevent the slicing blade 11 from deviating and shaking. The two spline rods 7 drive the top connecting plate 2 and the bottom slicing blade 11 to rise and fall synchronously. The downward movement completes the cutting of hawthorn, and the upward movement resets the blade. At the same time, the roller 12 drives the conveyor belt 3 to feed the material intermittently, so as to realize the continuous slicing of hawthorn. The whole system adopts cam linkage transmission, which has high transmission stability and small slicing vibration amplitude.

[0033] Example 2

[0034] The cleaning assembly includes a cleaning box 4 and an adjusting slide rail 8. Two compression springs 19 and a slide block 20 are symmetrically installed inside the adjusting slide rail 8. The slide block 20 is slidably connected to the inner wall of the adjusting slide rail 8, and the compression springs 19 abut against the slide block 20. A rotating seat 21 is fixedly connected to the end of the slide block 20 away from the compression springs 19. A rotating plate 22 is rotatably connected inside the rotating seat 21. A receiving plate 23 is rotatably connected to the ends of the two rotating plates 22 away from the slide block 20. A scraper 25 and a moving slide rail 24 are fixedly connected inside the cleaning box 4, and the scraper 25 abuts against the slicing blade 11. The slide block 20 is rotatably connected to the end of the sliding seat 20 away from the compression springs 19. One end of the device frame 1 is fixedly connected to the cleaning box 4. A threaded seat 30 is slidably connected in the movable slide rail 24. A threaded rod 29 is rotatably connected in the movable slide rail 24. The threaded rod 29 is threadedly connected to the threaded seat 30. A scraper 28 is fixedly connected to the end of the threaded seat 30 near the scraper 25. An air suction box 26 is fixedly connected to the lower surface of the scraper 25. An installation groove 31 is opened at the end of the cleaning box 4 away from the slicing knife 11. A collection box 27 is slidably connected in the installation groove 31. A lower pressure frame 15 is fixedly connected to the outer wall of the spline rod 7. The bottom end of the lower pressure frame 15 abuts against the receiving plate 23.

[0035] Linkage clamping: During the downward slicing process of the spline rod 7, it simultaneously drives the lower pressure frame 15 of the outer wall to press down the receiving plate 23, squeezing the rotating plates 22 that are inclined on both sides to open outward, and pushing the slide 20 in the opposite direction to compress the compression spring 19; when the slice moves upward to reset, the lower pressure frame 15 releases the pressure, and the compression spring 19 rebounds to push the slide 20 forward, causing the scraper 25 to always elastically fit the blade surface of the slicing blade 11, eliminating assembly gaps and ensuring scraping fit.

[0036] Adhesive Removal: Hawthorn sugar stains and fruit pulp fragments produced during slicing adhere to the blade surface. During the upward reset phase of the slicing blade 11, the polishing scraper 25 scrapes off the adhering material. The suction box 26 continuously generates negative pressure airflow, quickly adsorbing and guiding the scraped-off sticky debris and sugar stain dust, collecting them all in the bottom collection box 27. This prevents secondary splashing and adhesion of waste to the conveyor belt 3. The entire process requires no machine shutdown or disassembly for cleaning, achieving continuous slicing and simultaneous adhesive removal. When the slicing blade 11 is released from contact with its blade surface, the drive motor of the device drives the threaded rod 29 to rotate reciprocally, driving the threaded seat 30 to move laterally along the sliding rail 24. This causes the scraper frame 28 to clean the small adhering materials on the scraper 25, keeping the scraper 25 clean. When the scraper 25 is in contact with the slicing blade 11, the scraper frame 28 moves to one side of the slicing blade 11, without affecting the normal cleaning process of the scraper 25.

[0037] Example 3

[0038] The quick-release assembly includes a sleeve 16 and an insert 17. The sleeve 16 has multiple rolling grooves 36 evenly distributed around its circumference. A ball bearing 37 is installed in the rolling groove 36. A moving groove 32 is formed on the outer wall of the sleeve 16. A slider 33 is slidably connected in the moving groove 32. A push ring 34 is slidably connected to the outer wall of the sleeve 16. The inner ring wall of the push ring 34 is fixedly connected to the slider 33. A retaining groove 38 is formed on the outer wall of the insert 17. The ball bearing 37 and the retaining groove 38 are mutually locked and limited. A limiting ring 35 is fixedly connected to the outer wall of the sleeve 16. A return spring 39 is sleeved on the outer wall of the sleeve 16. The return spring 39 is located between the push ring 34 and the limiting ring 35. The connecting plate 2 is fixedly connected to the sleeve 16.

[0039] Normal locking condition: The return spring 39 continuously applies downward pressure to the push ring 34, and the inner wall of the push ring 34 squeezes the circumferentially arranged ball bearings 37, reducing the radius of the ball bearings' movement, so that the ball bearings 37 are locked into the groove 38 on the outer wall of the insertion tube 17. The ball bearings are used for point contact limiting, while restricting the insertion tube 17 from moving up and down and rotating around. There is no shaking during the slicing process, ensuring that the slice thickness is uniform.

[0040] Disassembly procedure: The operator manually pushes the push ring 34 against the spring force. The push ring 34 simultaneously drives the slider 33 to move upward along the moving groove 32, releasing the external pressure on the ball 37. The ball 37 is pushed outward by the insertion tube 17 and rolls out of the slot 38. The insertion tube 17 loses its limit and can be pulled out vertically downward directly.

[0041] The working principle of this invention is as follows: An external speed-regulating motor drives the roller 12 to rotate, which in turn drives the conveyor belt 3 to transport dried hawthorn at a uniform speed. The drive shaft 14 drives the synchronous phase cam blocks 9 at both ends to rotate. With the help of the cam linkage structure, the two spline rods 7 are driven to slide vertically back and forth along the guide tube 6. The anti-torsion characteristics of the spline are used to counteract the lateral torque of the cutting, which drives the connecting plate 2, quick-release assembly, and slicing blade 11 to move up and down synchronously at high frequency. The downward cutting cuts the dried hawthorn on the top surface of the conveyor belt 3, and the upward retraction avoids material feeding. The cycle repeats to complete the continuous slicing operation. The slicing lifting action is synchronously linked to the lower pressure frame 15 on the outer wall of the spline rod 7. The pressure frame 15, together with the receiving plate 23 and the rotating plate 22, realizes the elastic compensation of the spring 19, so that the scraper 25 always adaptively fits the blade surface of the slicing knife 11. During each blade retraction and reset phase, it automatically scrapes off the sugar stains and fruit pulp residues adhering to the blade surface. The negative pressure suction box 26 simultaneously adsorbs the waste and collects it into the collection box 27. The operator manually overcomes the spring force and pushes the push ring 34 upward. The push ring 34 simultaneously drives the slider 33 to move upward along the moving groove 32, releasing the external pressure on the ball 37. The ball 37 is pushed outward by the insertion tube 17 and rolls out of the slot 38. The insertion tube 17 loses its limit and can be directly pulled vertically downward to remove the slicing knife 11.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
