[0036] In actual application, the radius of the lower end of the inner cavity 21 is the same as that of the conveying through hole 24.

[0037] In the embodiment, the lower end of the screw rod 1 is in transmission connection with the driving assembly 4.

[0038] In the embodiment, the forming hole comprises an extrusion hole 32 and a die hole 33 which are arranged in communication, and the extrusion hole 32 is arranged in a large size at the top and a small size at the bottom. The crushed raw material is formed after passing through the extrusion hole 32 and the die hole 33 under the extrusion of the spiral assembly.

[0039] In the embodiment, the screw rod 1 comprises a base shaft 11, the spiral assembly comprises a plurality of protruding spiral flanges 12 arranged on the outer circle of the base shaft 11, a spiral groove 13 is formed between the spiral flange 12 and the base shaft 11, and the end of the spiral flange 12 is provided with a first blade edge 14. When the screw rod 1 rotates, the first blade edge 14 forms a strong extrusion force on the block-shaped raw material in the inner cavity 21, finally cuts and crushes the raw material, realizes the preliminary crushing of the large block-shaped raw material, and forms small block-shaped raw material.

[0040] In the embodiment, the outer edge of the spiral flange 12 is provided with a second blade edge 15. When the screw rod 1 rotates, the second blade edge 15 can further cut and crush the small block-shaped raw material cut and crushed by the first blade edge 14.

The interference ribs 23 are arranged longitudinally, obliquely or spirally on the inner wall of the inner cavity 21. Since the crushing work is completed in the inner cavity 21, the interference ribs 23 are arranged on the inner wall of the inner cavity 21. When the driving assembly 4 drives the screw rod 1 to rotate, the blocky raw materials are prevented from rotating with the screw rod 1 by the interference ribs 23, so that the crushing efficiency can be greatly improved.

[0042] In actual application, the interference ribs 23 are arranged longitudinally, obliquely or spirally on the inner wall of the inner cavity 21 to facilitate the blocky raw materials being crushed by the screw assembly of the screw rod 1 and being pushed downward.

[0043] In the embodiment, the lower part of the forming module 3 is provided with a taper structure 34 with a small upper part and a large lower part, and the side wall of the taper structure 34 corresponds to the forming hole.

The working efficiency of the extrusion forming can be greatly improved.

[0046] In the embodiment, the driving assembly 4 includes a motor 41, a gear box 42 and an output shaft 43. One end of the output shaft 43 is in transmission connection with the screw rod 1, the other end of the output shaft 43 is in transmission connection with the output end of the gear box 42, and the gear box 42 is in transmission connection with the output end of the motor 41. When the motor 41 works, the screw rod 1 is driven to rotate after being decelerated by the gear box 42.

[0047] In the embodiment, the device further includes a feeding box 5, a base 6, a receiving box 7, a machine shell 8 and a control unit 9. The feeding box 5 is located above the opening of the inner cavity 21, one end of the base 6 is fixedly connected with the forming module 3, the other end of the base 6 is provided with a discharge port 61, the receiving box 7 is arranged below the discharge port 61, the screw rod 1, the crushing container 2, the forming module 3, the driving assembly 4, the feeding box 5 and the base 6 are arranged inside the machine shell 8, the control unit 9 is installed on the machine shell 8, and the control unit 9 is in electrical connection with the driving assembly 4. The feeding box 5 is used to store the blocky raw materials and feed the blocky raw materials into the inner cavity 21; the base 6 is used to fix the forming module 3 and make the products after being reformed fall into the receiving box 7 through the discharge port 61; and the control unit 9 is used to control the motor 41 in the driving assembly 4 to work, so as to drive the screw rod 1 to work.

[0048] The working principle of the present application is as follows:

[0049] When the user uses it, the block-shaped raw material is put into the feeding box 5, and then the control unit 9 is started, the motor 41 is powered and rotated, and after being decelerated by the gear box 42, the screw rod 1 is driven to rotate, and the block-shaped raw material falls into the inner cavity 21 through the feeding box 5; since the screw rod 1 rotates, the block-shaped raw material cannot rotate with the screw rod 1 due to the interference ribs 23 on the inner wall of the inner cavity 21, and the sharp first cutting edge 14 will form a strong extrusion force on the block-shaped raw material, which will finally cut and crush the raw material, realize the preliminary crushing of the block-shaped raw material, and form small pieces of raw material, which slide downward along the inclined surface of the inner wall of the inner cavity 21 and fall into the spiral groove 13 and the gap between the screw rod 1 and the inner wall of the inner cavity 21; the screw rod 1 continues to rotate and pushes the preliminarily crushed small pieces of raw material downward under the action of the spiral flange 12, and since the outer edge of the spiral flange 12 is provided with a sharp second cutting edge 15, the small pieces of raw material in contact with the second cutting edge 15 will be further cut and crushed when the screw rod 1 rotates; at the same time, since the inner cavity 21 has a structure of large at the top and small at the bottom, when the crushed raw material is pushed downward by the spiral flange 12, the pressure from the spiral flange 12 and the inner wall of the inner cavity 21 will become larger and larger, so that the raw material is continuously crushed, and under the comprehensive action of multiple cutting and extrusion, the block-shaped raw material in the inner cavity 21 is formed into fine granular material at the lower end of the inner cavity 21; the screw rod 1 continues to rotate and pushes the fine granular material downward, which enters the multiple extrusion holes 32 on the forming die plate 3 through the spiral groove 13 and the conveying through hole 24 at the bottom of the inner cavity 21; since the extrusion holes 32 are tapered holes that are large at the top and small at the bottom, the fine granular material entering the extrusion holes 32 is further extruded and moves downward into the cylindrical compression hole 33, and under the action of strong extrusion force, the fine granular material is reformed into an elongated cylindrical product in the cylindrical compression hole 33; the screw rod 1 continues to rotate, the raw material is continuously pushed downward, and the reformed elongated cylindrical body continues to move downward under the pushing of the raw material behind it, when the elongated cylindrical body contacts the inclined surface outside the conical frustum structure 34, the elongated cylindrical body is broken by the inclined surface on the conical frustum structure 34, forming a shorter cylindrical granular material, and finally falling into the bottom receiving box 7 for collection, thereby completing the crushing and reformation process of the block-shaped raw material.

[0050] The block raw material crushing and extrusion molding device described in this invention can be applied in several ways. For example, frozen ice cubes from a household refrigerator can be placed into the feeding box 5 of this device. After crushing and reshaping, they can be quickly made into columnar granular ice (chewable ice) smaller than the original ice cubes. Compared to the original ice cubes, because these small-sized granular ice are formed by extruding crushed fine ice particles, a large number of pores are created inside. Therefore, they are softer and easier to chew than frozen ice cubes, and have a crisp and refreshing taste. At the same time, because the granular ice has a large number of pores inside, when users put this granular ice into various beverages and alcoholic drinks for chilling, the pores inside the granular ice will absorb a large amount of liquid, thereby changing the taste of the granular ice and making it more delicious. It also has a crisp and refreshing taste, making it a refreshing treat in summer.

[0051] The block raw material crushing and extrusion molding device described in this invention is not limited to making ice blocks into small-sized ice granules. Based on this working principle, it can also be applied to the crushing and reshaping of other types of large raw materials. It can be widely used in various fields such as mining, industrial production, agricultural production, consumer goods processing, and food processing. All equipment based on this working principle falls within the protection scope of this invention.

[0052] Example 2:

[0053] like Figure 8 As shown, the upper end of the screw 1 is connected to the drive assembly 4 for transmission.

[0054] The difference between this embodiment 2 and embodiment 1 is that the upper end of the screw 1 is connected to the drive assembly 4 for transmission. The rest of the structure and working principle are the same as in embodiment 1, and will not be repeated.

[0055] Example 3:

[0056] In the actual operation of Embodiment 1, when the screw 1 pushes the raw material downward, it generates a downward thrust F1. At the same time, it is pushed upward by the raw material, causing the screw 1 to move upward and generate an upward reaction force F2. This can easily damage the structural components of the device, affect the reliability and durability of the product operation, and reduce the product's service life.

[0057] To address this technical problem, the present invention makes the following improvements:

[0058] like Figures 9 to 11 As shown, the output end of the gearbox 42 is provided with an output gear 423, and an upper bearing 422 is provided on the upper side of the output gear 423. The output shaft 43 is coaxially fixedly installed with the upper bearing 422 and the output gear 423, and extends out of the gearbox 42 to be connected to the screw 1 for transmission. The upper bearing 422 is a thrust bearing or a tapered roller bearing.

[0059] In the embodiment, the gear box 42 comprises an upper cover 421 and a lower cover 426, the upper cover 421 and the lower cover 426 are fixedly connected, the upper bearing 422 is arranged in the upper cover 421, and the output shaft 43 extends out of the upper cover 421.

[0060] In the embodiment, a flange ring 431 is arranged on the outer circle of the output shaft 43, the flange ring 431 divides the outer circle of the output shaft 43 into an outer upper mounting portion 432 and an outer lower mounting portion 433, the output gear 423 and the lower bearing 425 are fixedly installed on the outer lower mounting portion 433, the output gear 423 abuts against the lower end of the flange ring 431, and the upper bearing 422 is fixedly installed on the outer upper mounting portion 432 and abuts against the upper end of the flange ring 431.

[0061] In the embodiment, the output shaft 43 is internally provided with a mounting hole 434, an annular step portion 435 is arranged on the inner wall of the mounting hole 434, the annular step portion 435 divides the mounting hole 434 into an inner upper mounting portion 436 and an inner lower mounting portion 437, the inner upper mounting portion 436 is a polygonal recess, a polygonal flange is arranged at the lower end of the screw rod 1, the polygonal flange is inserted into the inner upper mounting portion 436 and abuts against the upper end of the annular step portion 435, and the output shaft 43 is driven to rotate when the screw rod 1 rotates.

[0062] In the embodiment, the polygonal flange is provided with a screw hole, a fastening screw 424 is arranged in the inner lower mounting portion 437, and the upper end of the fastening screw 424 is fixedly connected with the screw hole of the polygonal flange through the annular step portion 435. The screw rod 1 is fixed on the annular step portion 435 in the inner hole of the output shaft 43 through the fastening screw 424, so that the screw rod 1 is prevented from moving upward.

[0063] In the embodiment, the lower cover 426 is internally provided with the lower bearing 425, the lower bearing 425 is fixedly installed on the outer lower mounting portion 433 of the output shaft 43, and the lower bearing 425 is located on the lower side of the output gear 423.

[0064] When the embodiment works, the motor 41 drives the gear box 42 to rotate the output shaft 43, and the output shaft 43 drives the screw rod 1 to rotate, so that the raw materials are crushed and extruded, and a downward pushing force F1 is generated to push the raw materials downward, and the screw rod 1 is subjected to an upward reaction force F2, so that the screw rod 1 tends to move upward; since the screw rod 1 is fixed on the annular step portion 435 in the inner hole of the output shaft 43 by the fastening bolt 424, the screw rod 1 is prevented from moving upward; at this time, the reaction force F2 of the screw rod 1 is transmitted to the annular step portion 435 in the inner hole of the output shaft 43 through the fastening bolt 424, and then transmitted to the flange ring 431 on the outer circle of the output shaft 43, and further transmitted to the upper bearing 422; since the gear box 42 is installed at the lower end of the forming module 3, the upper end of the upper bearing 422 abuts against the forming module 3 through the upper cover 421, and the downward pushing force F1 of the screw rod 1 is transmitted to the forming module 3 through the raw materials; since the upper bearing 422 is a thrust bearing or a tapered roller bearing, the upper bearing 422 can bear a large axial pressure; and the forming module 3 and the upper cover 421 are made of a rigid material and can bear a large pressure. Finally, the downward pushing force F1 and the reaction force F2 of the screw rod 1 are counteracted by the upper bearing 422, the forming module 3 and the upper cover 421, so that the effect of force balance is achieved.

[0065] The difference between the third embodiment and the first embodiment is that the structure of the driving assembly 4 is different, and the remaining structure and working principle are the same as those of the first embodiment, which will not be repeated.

[0066] Embodiment Four:

[0067] In the actual working process of the first embodiment, it is found that the crushing effect of some large pieces of raw materials directly extruded by the screw assembly is not very ideal, the crushing effect is not optimal, the feeding is not smooth enough, and the working efficiency is affected.

[0068] In view of the technical problem, the present application is improved as follows:

[0069] As shown in Figure 12 and Figure 13 , the screw rod 1 above the screw assembly is fixed with a stirring knife 17. Through the stirring knife 17, the large pieces of raw materials can be first cut into small pieces of raw materials by the screw rod 1, and then the small pieces of raw materials after cutting are crushed and extruded by the screw assembly, so that the crushing of the raw materials is accelerated, the crushing effect is better, the feeding is smoother, and the working efficiency is higher.

[0070] In the embodiment, the upper end of the screw rod 1 extends into the feeding box 5, and the stirring paddle 16 is fixed on the screw rod 1 in the feeding box 5. When the driving assembly 4 drives the screw rod 1 to rotate, the stirring paddle 16 is driven to work, so that the raw materials in the feeding box 5 are stirred and promoted to fall into the crushing container 2.

[0071] In the embodiment, the blade 17 is fixed with a scraper 18 or a brush 19 on the screw 1 above the blade 17. When the driving assembly 4 drives the screw 1 to rotate, the accumulated materials on the inner wall of the crushing container 2 are scraped or cleaned by the scraper 18 or the brush 19, so that the materials fall into the lower area of the crushing container 2, are extruded and crushed by the screw 1, and are pushed downward, thereby accelerating the crushing efficiency and reducing the waste of raw materials.

[0072] The difference between the fourth embodiment and the first embodiment is that the stirring paddle 16, the blade 17, the scraper 18 or the brush 19 are added on the screw 1, so that the device is more smooth and faster in discharging, thereby greatly improving the crushing efficiency. The remaining structure and working principle are the same as those of the first embodiment, and are not repeated here.

[0073] The embodiments of the present application are described above with reference to the drawings, but the present application is not limited to the specific embodiments described above, and the specific embodiments described above are only illustrative but not restrictive. Those skilled in the art can make many forms under the inspiration of the present application without departing from the purpose of the present application and the scope protected by the claims, and these all belong to the protection scope of the present application.
