Abstract

The present invention discloses a crushing device for food processing, comprising a support frame, which is mounted on external equipment. A crushing mechanism is arranged on the support frame, and an outer shell is mounted on the support frame. The driving shaft and the driven shaft are respectively rotatably connected to the outer shell, and the driving mechanism is cooperatively connected to the support frame and the driving shaft. A hexagonal rod is mounted on the driving shaft. By using a combination of a flexible sleeve and a crushing wheel, the efficiency and quality of food crushing are significantly improved.

This innovative crushing method can process foods of various hardnesses and textures, thereby improving the application range and working efficiency of the equipment.

Description

Technical Field

[0001] The present invention relates to the technical field of crushing for food processing, and more particularly to a crushing device for food processing. Background Art

[0002] In the current food processing industry, crushing is a common and important process. Most existing food processing crushing devices adopt double-roller crushing. This method usually uses two relatively rotating crushing rollers to crush food through the meshing action between them. The surface of the crushing rollers is usually designed with specific patterns or protrusions to enhance the crushing effect. However, this traditional double-roller crushing method has a significant limitation.

[0003] This limitation is primarily due to the relatively small actual meshing area between the two crushing rollers. While the crushing rollers may appear substantial, only the small area where the two rollers are in contact is truly functional. This limited meshing area directly impacts the effectiveness and efficiency of crushing, limiting not only the amount of food that can be processed at a single time but also potentially leading to uneven crushing, with some food not being fully processed. In this case, either the crushing process needs to be repeated multiple times, or the quality of the final product is compromised. Summary of the Invention

Two engaging sleeves 49 are symmetrically provided on the fitting sleeve 38, and the two engaging sleeves 49 are respectively provided with inclined surfaces 50. The push rod 48 is fitted on the inclined surfaces 50, and the two engaging sleeves 49 are respectively provided with fitting grooves 51.The pull rod 47 is slidably connected to the fitting groove 51, and a push spring 52 is provided between the two engaging sleeves 49. A plurality of operating holes 53 are respectively provided on both sides of the housing 2. Each operating hole 53 allows observation of the interior of the housing 2, and the two engaging sleeves 49 can be grasped and brought closer together through the operating holes 53.

[0036] Working principle: When the corresponding food needs to be crushed, first install the bonding plate 29 on the housing 2, then the multiple rotating grooves 30 are respectively rotated and connected to the driving shaft 3 and the driven shaft 4, and then the multiple top plates 32 are respectively inserted between the crushing wheels 7, and the other side of the bonding plate 29 is also bonded to the flexible sleeve 12. At this time, the gap can be filled by the bonding between the bonding plate 29 and the flexible sleeve 12, and the bonding between the top plate 32 and the crushing wheel 7 can also fill the gaps between the multiple crushing wheels 7, and then the corresponding food is introduced through the feed hopper 31. When the food is crushed, it can be fully guaranteed that the food will be engaged and crushed between the crushing wheel 7 and the flexible sleeve 12. At this time, the feed port is installed, and then the starting motor 16 and the reducer 15 can drive the rotation of the driving shaft 3. Since the driving wheel 17 and the driven wheel 18 are engaged with each other, the driven shaft 4 can be driven to rotate synchronously, and the diameter of the driven wheel 18 is larger than the diameter of the driving wheel 17. Therefore, the rotation speed of the driving shaft 3 will be greater than the rotation speed of the driven shaft 4. At this time, the corresponding food will enter the flexible sleeve through the friction provided by the transverse groove 13 and the follower groove 14. 12 and the crushing wheel 7, since the flexible sleeve 12 is a rubber product, and a plurality of follower springs 11 are installed between the flexible sleeve 12 and the inner wheel 10, the flexible sleeve 12 can be applied with a multi-point thrust, so that the flexible sleeve 12 can cover the crushing wheel 7. At this time, the food is in the covering area of ​​the flexible sleeve 12 and the crushing wheel 7. Since the diameters of the flexible sleeve 12 and the crushing wheel 7 are the same, but the speed of the driving wheel 17 is greater than the rotation of the driven wheel 18, the two will rotate relative to each other. At this time, the food in the covering area of ​​the flexible sleeve 12 and the crushing wheel 7 will not only be affected The crushing force of the squeeze will also be affected by the grinding force generated by the different speeds of the flexible sleeve 12 and the crushing wheel 7. Therefore, the food can be effectively crushed and ground, and the friction force is increased by the transverse groove 13 and the follower groove 14, thereby ensuring the crushing effect. The crushed food will flow onto the screening plate 35 at the lower end, and will leak out when it can pass through the sieve hole 36. When the diameter is larger than the diameter of the sieve hole 36, it will continue to be ground by the crushing wheel 7 and the flexible sleeve 12 so that it can meet the diameter of the sieve hole 36, and then be discharged, thereby completing the food crushing process.

[0037] When it is necessary to replace the sieve holes 36 of corresponding diameters according to different situations, first pass the positioning rod 33 through the side plate 34, and then make the side plate 34 fit on the lower end surface of the support frame 1. Then, at this time, the bottom rod 44 is slidably connected to the bottom sleeve 45, and the corresponding thrust can be applied by the spring 46. Due to the unidirectional setting of the one-way sleeve 42, when the fitting sleeve 38 is pushed upward, the telescopic plate 41 fits on the one-way sleeve 42 and the clamping spring 43 is compressed. Then the telescopic rod 40 slides backward along the telescopic hole 39 until multiple telescopic plates 41 are respectively stuck on the one-way sleeve 42, thereby completing the fixing process. When it is necessary to unlock, first pass through the shell 2 The operating hole 53 on the side wall can be used to extend the hand into the shell 2, and then grab the two engaging sleeves 49. At this time, the upper and lower ends exert force simultaneously to drive the two engaging sleeves 49 to approach each other. When the two engaging sleeves 49 are not subjected to external force, the push spring 52 can make the two engaging sleeves 49 in an outward expansion state. When the two engaging sleeves 49 approach each other, the push rod 48 is slidably connected to the inclined surface 50, and then expands outward with the inclined surface 50. Under the action of the pull rod 47, the telescopic rod 40 will be driven to expand outward, and the telescopic plate 41 will make it slide, thereby releasing the clamping between the telescopic plate 41 and the one-way sleeve 42, and finally releasing the connection, and the screening plate 35 can be taken out.

[0038] See also Figure 1-Figure 3 In order to achieve stable rotation of the driving shaft 3 and the driven shaft 4, a counterweight mechanism is added. The counterweight mechanism includes a first counterweight wheel 19, a second counterweight wheel 20 and an insertion rod 21. The first counterweight wheel 19 is attached to the driving shaft 3, and the second counterweight wheel 20 is attached to the driven shaft 4. A plurality of insertion rods 21 are respectively installed on the first counterweight wheel 19 and the second counterweight wheel 20. A plurality of insertion holes 22 are respectively opened on the side walls of the driving shaft 3 and the driven shaft 4. The insertion rods 21 are respectively slidably connected to the insertion holes. In the hole 22, a screw 23 is coaxially provided on the driving shaft 3 and the driven shaft 4, and a mounting sleeve 24 is threaded on the screw 23. A plurality of expansion holes 25 are provided on the side wall of the mounting sleeve 24. A limit rod 26 is slidably provided in each expansion hole 25, and a tension spring 27 is provided in each expansion hole 25. The tension spring 27 is connected to the limit rod 26. An annular groove 28 is respectively provided on the first counterweight wheel 19 and the second counterweight wheel 20, and the limit rod 26 is slidably connected in the annular groove 28.

[0039] Working principle: When the driving shaft 3 and the driven shaft 4 are rotating, the continuity of the rotation of the driving shaft 3 and the driven shaft 4 can be improved by adding the first counterweight wheel 19 and the second counterweight wheel 20. First, the first counterweight wheel 19 and the second counterweight wheel 20 are respectively fitted on the driving shaft 3 and the driven shaft 4. At this time, multiple insertion rods 21 are respectively inserted into the insertion holes 22. Since the rotation of the driving shaft 3 and the driven shaft 4 is different, different counterweight wheels are required. Then, the two counterweight wheels are respectively inserted into the screw rod 23, and then the mounting sleeve 24 is threadedly connected to the screw rod 23, so that the two mounting sleeves 24 are respectively fitted on the two counterweight wheels, and then the installation process is completed. At this time, the multiple limit rods 26 and the annular groove 28 are in a parallel state. When the driving shaft 3 When the counterweight wheel 4 and the driven shaft 4 rotate respectively, the connection between the insertion rod 21 and the insertion hole 22 can provide a corresponding circumferential connection, and then the mounting sleeve 24 will rotate accordingly. Since the limit rod 26 is slidably connected in the expansion hole 25, and the tension spring 27 is connected to the limit rod 26, the limit rod 26 will rotate accordingly. When the limit rod 26 rotates, it will expand outward due to centrifugal force, and since the limit rod 26 and the annular groove 28 are in a parallel state, multiple limit rods 26 can be inserted into the annular groove 28. At this time, the counterweight wheel in the rotating state has an extra layer of protection in the axial direction. When in a stationary state, the limit rod 26 does not contact the annular groove 28 under the action of the tension spring 27, thereby ensuring that the counterweight wheel is in a stably connected state when rotating.
