Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, in particular to a soybean fibrous protein double-helix extrusion fixed-length cutting device. Background Art

[0002] Soy protein is a protein product with a muscle fiber structure made from non-GMO soybeans through advanced processes such as heating, extrusion, and puffing. The main raw material is soy protein isolate, which is a high-purity protein extracted from soybeans. Soy protein is rich in high-quality protein and has a low fat content and relatively low calories. It is suitable for people who need to supplement protein but are worried about excessive fat intake.

[0003] High-quality soybeans are selected as raw materials. After soaking and softening, they are ground to form soybean slurry, and the fibers are separated by filtering or centrifugation to obtain pure soybean emulsion. The soybean emulsion is heated and acid is added to make the protein coagulate and precipitate. The acidic substances and impurities are then removed by water washing to obtain pure soybean protein precipitate. The washed protein precipitate is mixed with an appropriate amount of water and additives, and then extruded and puffed by a twin-screw extruder under high temperature and high pressure to make the protein molecules undergo physical and chemical changes to form fibrous texture protein, which is then cut into the required length and shape by a cutting machine. Common shapes are round, rectangular and fragmented.

[0004] However, the fixed-length cutting device in the prior art cuts the dried and flattened rectangular soy fibrous protein through a rotating blade, and achieves fixed-length cutting by adjusting the rotation speed of the rotating blade and the conveying speed of the conveying mechanism. However, the cutting method in the prior art usually uses a vertically downward cutter to cut the raw material. However, the dried soy fibrous protein has a certain toughness, and directly using a cutter to cut downward may not be able to completely divide the raw material; therefore, it does not meet the existing needs.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1: This example aims to solve the problem that the dried soy protein has a certain toughness and it may not be possible to cut the raw material directly by cutting it downward. Figures 1 to 14 A double-screw extrusion fixed-length cutting device for soybean fibrous protein comprises a double-screw extrusion device 1 and a conveying device 2. The double-screw extrusion device 1 comprises a cabin 11, in which two screw rods 12 are arranged, an extrusion port 15 is arranged at one end of the cabin 11, and a feeding port 16 is arranged on the side wall of the cabin 11, and the extrusion port 15 points to the conveying device 2.

[0038] The raw material enters the chamber 11 through the feed port 16 , is processed by the screw rod 12 in the chamber 11 , and is finally extruded through the extrusion port 15 and conveyed to the conveying device 2 .

[0039] The conveying device 2 comprises a cutting shell 21 , a conveying belt 22 is arranged inside the cutting shell 21 , and a flattening roller 23 and a push-pull cutting assembly 4 are arranged above the conveying belt 22 .

[0040] The conveying device 2 is used to receive the raw materials expanded and extruded by the double-screw extruder 1, the conveyor belt 22 is used to transport the processed raw materials, and the flattening roller 23 located above the conveyor belt 22 is used to flatten the raw materials. The flattened raw materials are easier to be cut by the cutter 46.

[0041] The push-pull cutting assembly 4 includes a cutter 46, which is installed at the bottom of a slide plate 45. The slide plate 45 is slidably connected to the outer wall of a fixed rod 44. A connecting rod 47 is installed above the slide plate 45. A sliding shaft 410 is fixed to the side wall of the connecting rod 47. The sliding shaft 410 is slidably connected in a wave groove 49, and the wave groove 49 is opened in a fixed square tube 48.

[0042] The cutter 46 is used to cut the raw materials placed on the conveyor belt 22. The cutter 46 is installed on the slide plate 45 and will slide synchronously with the sliding of the slide plate 45. The design of the fixed rod 44 limits the sliding of the slide plate 45. The slide plate 45 is fixedly connected to the connecting rod 47 so that the cutter 46 moves with the movement of the connecting rod 47. The connecting rod 47 can cut the raw materials by descending. The connecting rod 47 is slidably connected in the fixed square tube 48. A wave groove 49 is provided in the fixed square tube 48. The connecting rod 47 is slidably connected in the fixed square tube 48 through a sliding shaft 410. The design of the wave groove 49 makes the connecting rod 47 swing in the front and back directions during the descent process. Through this swing, the cutter 46 has a pushing and cutting action when cutting the raw materials. Through this action, the cutting effect of the raw materials can be further improved, and it can be effectively ensured that the cutter 46 can cut the raw materials.

[0043] One end of the screw rod 12 passes through the extrusion port 15 and is away from the extrusion port 15 . The end of the screw rod 12 away from the extrusion port 15 is fixedly connected to a screw motor 13 . The two screw rods 12 are connected by a belt 14 . A heating block 17 is provided on the outer wall of the cabin 11 .

[0044] The screw motor 13 is used to drive the screw rod 12 to rotate, and the belt 14 drives the two screw rods 12 to rotate synchronously. The heating block 17 is used to heat the space inside the cabin 11, so that the raw materials located in the cabin 11 are dried and expanded.

[0045] A rotating assembly 3 is provided in the cutting shell 21, and the rotating assembly 3 includes a rotating disk 31 rotatably connected in the cutting shell 21, a first gear 32 is fixedly connected to the outer wall of the rotating disk 31, the first gear 32 is meshingly connected to the second gear 33, and a driving motor 34 is fixedly connected to one side of the second gear 33, and the driving motor 34 is installed on the side wall of the cutting shell 21.

[0046] The rotating assembly 3 is used to drive the cutter 46 to rotate and drive the cutter 46 to cut the raw material. Since the rotating disk 31 is composed of two hollow rings, and the driving shaft 411 needs to be installed at the hollow part of the rotating disk 31, the rotating disk 31 is driven to rotate through the transmission of the first gear 32 and the second gear 33, and the driving motor 34 is used to drive the rotating disk 31 to rotate.

[0047] The push-pull cutting assembly 4 includes a slot 41 opened in the rotating disk 31, a slider 42 is slidably connected in the slot 41, a spring 43 is fixedly connected to one side of the slider 42, the other end of the spring 43 is fixedly connected in the slot 41, a fixed rod 44 is fixedly connected to one side of the slider 42, and a fixed square tube 48 is fixedly connected to the upper surface of the rotating disk 31.

[0048] A driving shaft 411 is fixedly connected to one side of the cutting housing 21 , and a first driving block 412 is fixedly connected to the side wall of the driving shaft 411 . The first driving block 412 is used to abut against the connecting rod 47 .

[0049] When the rotating disk 31 rotates, it will drive the connecting rod 47 to rotate synchronously. During the rotation, the connecting rod 47 will resist the inclined surface of the No. 1 driving block 412. The No. 1 driving block 412 can resist the connecting rod 47, so that the connecting rod 47 can be driven to slide downward. The connecting rod 47 is designed with a wave groove 49 and a sliding shaft 410, so that the connecting rod 47 will swing in the process of descending, and will swing in the front and back directions. Through this swing, the cutter 46 will have a pushing and cutting action when cutting the raw material. This action can further improve the cutting effect of the raw material, and effectively ensure that the cutter 46 can cut the raw material.

[0050] The slide plate 45 is slidably connected in the fixing rod 44, and the fixing rod 44 is installed in the first slide block 42. The slide plate 45 descends as the connecting rod 47 descends, so the first slide block 42 will slide downward synchronously, so that the cutting process of the raw material is completed by the cutter 46. The design of the first spring 43 ensures that the slide plate 45 can be quickly reset upward after the cutting process is carried out to facilitate the next cutting process.

[0051] Example 2: This example is intended to help solve the problem that the raw material with a certain toughness may not be completely cut off by cutting. This example is an explanation based on Example 1. For details, please refer to Figures 1 to 14An offset assembly 5 is provided at the bottom of the slide plate 45. The offset assembly 5 includes a groove 51 and a limiting groove 52 opened in the slide plate 45. A mounting block 57 is slidably connected in the groove 51, and a second slider 53 is slidably connected in the limiting groove 52. A fixed shaft 54 ​​is fixedly connected to one side of the second slider 53. The outer wall of the fixed shaft 54 ​​is rotatably connected to a gear shaft 55. The gear shaft 55 is fixedly connected to the corner of the mounting block 57 close to the slide plate 45. The gear shaft 55 is meshingly connected with a tooth block 56. The tooth block 56 is fixedly connected in the slide plate 45. The bottom of the mounting block 57 is fixedly connected to the cutter 46.

[0052] A No. 2 spring 58 is fixedly connected to the upper surface of the mounting block 57 , and the other end of the No. 2 spring 58 is fixedly connected to the upper surface of the slide plate 45 located in the groove 51 .

[0053] If the cutting surface of the cutter 46 is not smooth enough, the raw material may not be completely cut during cutting, and the raw material may have filamentary connections. Therefore, through the design of the offset component 5, the cutter 46 can be driven to deviate at a certain angle after cutting. Through this offset, the connected raw materials can be torn off to ensure that the raw materials can be completely cut off.

[0054] The groove 51 is provided so that the cutter 46 installed at the bottom of the mounting block 57 has a telescopic function. The design of the limit groove 52 and the second slider 53 ensures that the mounting block 57 can slide in the vertical direction, thereby ensuring the cutting stability. The slide plate 45 is driven by the first drive block 412 to slide downward, so that when the cutter 46 cuts the raw material, through the telescopic design, when the cutter 46 cuts to the lowest point, the slide plate 45 continues to slide downward, and the elastic force released by the second spring 58 can drive the cutter 46 to cut the raw material with greater force, thereby ensuring that the cutter 46 can cut the raw material.

[0055] During the relative sliding of the mounting block 57 and the slide plate 45, the tooth block 56 in the slide plate 45 will drive the gear shaft 55 to rotate, and the gear shaft 55 is arranged at the corner of the mounting block 57, so the mounting block 57 will swing to the right. At this time, the cutter 46 has cut the raw material, and under the drive of the No. 2 spring 58, a certain force is applied to the conveyor belt 22. Through this rotation, the cutter 46 can tear off the raw material that has not been completely cut off.

[0056] Embodiment 3: This embodiment is intended to help solve the problem that the cutter 46 may be worn during cutting. This embodiment is an explanation based on Embodiment 2. For details, please refer to Figures 1 to 14A grinding assembly 6 is arranged above the rotating disk 31, and the grinding assembly 6 includes a telescopic shell 61 fixedly connected to the surface of the cutting shell 21, a telescopic inner rod 62 is slidably connected in the telescopic shell 61, a telescopic spring 63 is fixedly connected to the bottom of the telescopic inner rod 62, and the other end of the telescopic spring 63 is fixedly connected in the telescopic shell 61. A mounting groove 64 is opened in the telescopic inner rod 62, and a rotating shaft 65 is rotatably connected in the mounting groove 64. The rotating shaft 65 is fixedly connected to the side wall of the connecting plate 67, and a grinding plate 68 is fixedly connected to the end of the connecting plate 67 away from the telescopic shell 61.

[0057] The rotating shaft 65 is rotatably connected in the mounting groove 64 via a torsion spring 66 .

[0058] A second driving block 69 is fixedly connected to the side wall of the driving shaft 411 , and the second driving block 69 is used to abut against the connecting rod 47 .

[0059] When the cutter 46 rotates to the grinding assembly 6, the cutter 46 contacts the surface of the grinding plate 68, and the second drive block 69 in the connecting rod 47 contacts it, and then slides upward. At the same time, under the design of the wave groove 49 and the drive shaft 411, the cutter 46 will swing during the sliding process, and the cutter 46 contacts the grinding plate 68. Through the swing of the cutter 46, it can be ensured that the cutter 46 swings left and right on the grinding plate 68. Through this swing, the grinding of the cutter 46 can be completed, the sharpness of the cutter 46 is improved, and the cutting effect is guaranteed. The second drive block 69 is designed to be an inverted triangle, so that the connecting rod 47 is contacted by the second drive block 69 for a longer time, so the grinding degree can be guaranteed. The telescopic shell 61 and the telescopic The design of the inner rod 62 can ensure that the connecting rod 47 prolongs the grinding time during the rotational grinding process, thereby ensuring the grinding effect. At the same time, the elastic force released by the telescopic spring 63 can ensure the contact force between the cutter 46 and the grinding plate 68 to ensure the grinding effect. The grinding plate 68 and the telescopic inner rod 62 are connected by the torsion spring 66, and the cutter 46 contacts the lower half of the grinding plate 68. Therefore, the grinding plate 68 will be rotated by the resistance of the cutter 46. Through the rotation of the grinding plate 68, it can be ensured that the grinding plate 68 grinds the cut surface of the cutter 46. At the same time, through the rotation of the grinding plate 68, it can effectively prevent the cutter 46 from being stuck by the grinding plate 68 and unable to rotate, thereby ensuring the normal progress of the cutting work.
