Description

Technical Field

[0001] This utility model relates to the technical field of rice noodle production equipment, and in particular to a rice noodle extrusion machine. Background Technology

[0002] Rice noodles are a popular traditional food, and the extrusion machine is one of the most crucial pieces of equipment in its production process. It processes the rice noodle raw material into the desired noodle shape. The extrusion machine typically consists of an extruder body and a die head. The spiral blades inside the extruder body rotate and push the raw material, which ultimately passes through the holes in the die head to form rice noodles.

[0003] In existing rice noodle extrusion machines, there are some problems with the way the die head is fixed to the extruder body. The common fixing method is to use multiple bolts for connection and fixation. When it is necessary to change to different specifications of die head to produce rice noodles of different shapes or thicknesses, the process of disassembling and installing bolts is cumbersome, consumes a lot of time, and affects production efficiency.

[0004] Meanwhile, the connection structure of the spiral blades inside the extruder body also needs improvement. The traditional connection method between the spiral blades and the drive components is not convenient for disassembly and installation when the spiral blades need to be repaired or replaced, which increases maintenance costs and time. Therefore, developing a rice noodle extruder with a firmly fixed die head that is easy to disassemble and assemble, and with a stable connection of the spiral blades that is easy to maintain, has become a problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rice noodle extrusion machine that solves the problems of cumbersome die head assembly and disassembly, and inconvenient spiral blade connection and maintenance. By setting a specific fixing mechanism, the die head can be quickly fixed and disassembled, while an optimized connection mechanism ensures stable connection of the spiral blades and facilitates maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rice noodle extrusion machine includes an extruder body and a die head. A first fixed plate is fixedly connected to the end of the extruder body, and a second fixed plate that cooperates with the first fixed plate is fixedly sleeved on the die head. Two symmetrically arranged U-shaped blocks are fixedly connected to the side wall of the extruder body. Each U-shaped block is provided with a fixing mechanism for fixing the die head. The fixing mechanism includes a rotating block rotatably connected to the U-shaped block. A threaded rod is fixedly connected to the end of the rotating block, and a nut is threadedly connected to the threaded rod. A fixing ring is rotatably connected to the end of the nut near the U-shaped block. Two symmetrically arranged slots are provided on both the first and second fixed plates. The slots cooperate with the threaded rod, and the width of the fixing ring is greater than the width of the slots. A helical blade is provided inside the extruder body, and a connecting mechanism for fixing the helical blade is provided inside the extruder body.

[0008] Preferably, the connecting mechanism includes a rectangular rod rotatably connected to the inner wall of the extruder body, and a rectangular groove that cooperates with the rectangular rod is provided on the central axis of the spiral blade.

[0009] Preferably, the rectangular rod has grooves at both the top and bottom ends, and positioning blocks are slidably connected in both grooves. The lower ends of the two positioning blocks are elastically connected to the inner wall of the groove on the same side by springs.

[0010] Preferably, two symmetrically arranged positioning holes are provided on the central axis of the spiral blade, both positioning holes are engaged with positioning blocks, and both positioning holes are connected to rectangular grooves.

[0011] Preferably, a motor is fixedly connected to the end of the extruder body, and the output shaft of the motor is fixedly connected to the end of the rectangular rod.

[0012] Preferably, a feed hopper connected to the upper end of the extruder body is installed thereon.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. By setting up a fixing mechanism, the die head and the extruder body can be quickly fixed and disassembled. When the die head needs to be installed, the second fixing plate is attached to the first fixing plate, the rotating block is rotated to make the threaded rod enter the bayonet, and then the nut is rotated to drive the fixing ring to move until the fixing ring is tightly pressed on the first fixing plate and the second fixing plate to complete the fixing. Disassembly can be performed by reversing the operation. There is no need to remove multiple bolts, which greatly improves the efficiency of die head replacement.

[0015] 2. The connecting mechanism uses a rectangular rod and a rectangular groove to effectively transmit the motor's power and drive the spiral blades to rotate stably. This avoids slippage that may occur in traditional connecting methods, ensuring the stability of the spiral blades pushing raw materials. The positioning block and spring further enhance the connection stability between the spiral blades and the rectangular rod. When installing the spiral blades, the positioning block is engaged in the positioning hole under the action of the spring, preventing the spiral blades from moving axially during operation. When it is necessary to disassemble the spiral blades, simply press the positioning block to retract it into the groove, and the spiral blades can be removed from the rectangular rod. The operation is convenient and easy to maintain and replace. Attached Figure Description

Detailed Implementation

[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] Reference Figure 1-6A rice noodle extrusion machine includes an extruder body 1 and a die head 6. A first fixed plate 4 is fixedly connected to the end of the extruder body 1. A second fixed plate 5 that cooperates with the first fixed plate 4 is fixedly sleeved on the die head 6. The first fixed plate 4 and the second fixed plate 5 are matched in shape and size. When the two are in contact, the die head 6 can be accurately connected to the extruder body 1.

[0025] Two symmetrically arranged U-shaped blocks 7 are fixedly connected to the side wall of the extruder body 1. Each U-shaped block 7 is equipped with a fixing mechanism for fixing the die head 6. The fixing mechanism includes a rotating block 8 rotatably connected to the U-shaped block 7. The rotating block 8 can rotate freely on the U-shaped block 7 to facilitate adjustment of the position of the threaded rod 9. The end of the rotating block 8 is fixedly connected to the threaded rod 9, and a nut 10 is threadedly connected to the threaded rod 9. A retaining ring 11 is rotatably connected to the end of the nut 10 near the U-shaped block 7. The rotatable connection means that when the nut 10 rotates, the retaining ring 11 will not rotate with it, but will only move along the axial direction of the threaded rod 9.

[0026] Both the first fixed plate 4 and the second fixed plate 5 have two symmetrically arranged bayonet slots 12. The bayonet slots 12 cooperate with the threaded rod 9, and the threaded rod 9 can be inserted into the bayonet slots 12 to perform preliminary positioning of the first fixed plate 4 and the second fixed plate 5. The width of the fixing ring 11 is greater than the width of the bayonet slot 12. When the fixing ring 11 is pressed on the first fixed plate 4 and the second fixed plate, it can cover the bayonet slot 12, thereby firmly fixing the first fixed plate 4 and the second fixed plate 5 together.

[0027] The extruder body 1 is equipped with a spiral blade 14 inside, which is used to push rice flour raw materials. The extruder body 1 is also equipped with a connecting mechanism for fixing the spiral blade 14. The connecting mechanism includes a rectangular rod 13 rotatably connected to the inner wall of the extruder body 1. A rectangular groove 15 that cooperates with the rectangular rod 13 is opened on the central shaft of the spiral blade 14. The rectangular rod 13 is inserted into the rectangular groove 15 to realize the transmission connection between the rectangular rod 13 and the spiral blade 14.

[0028] The rectangular rod 13 has grooves 16 at both the top and bottom ends. A positioning block 17 is slidably connected in each of the two grooves 16. The positioning block 17 can slide in the groove 16 in a direction perpendicular to the axis of the rectangular rod 13. The lower ends of the two positioning blocks 17 are elastically connected to the inner wall of the groove 16 on the same side by springs 18. The springs 18 provide outward elastic force to the positioning blocks 17, so that the positioning blocks 17 can pop out of the groove 16.

[0029] Two symmetrically arranged positioning holes are provided on the central axis of the spiral blade 14. Both positioning holes are matched with positioning blocks 17 and are connected to rectangular grooves 15. When the rectangular rod 13 is inserted into the rectangular groove 15, the positioning block 17 is engaged in the positioning hole under the action of the spring 18 to axially position the spiral blade 14.

[0030] A motor 3 is fixedly connected to the end of the extruder body 1. The output shaft of the motor 3 is fixedly connected to the end of the rectangular rod 13. When the motor 3 is working, it drives the rectangular rod 13 to rotate, which in turn drives the spiral blade 14 to rotate. A feed hopper 2 connected to the upper end of the extruder body 1 is installed. The rice flour raw material enters the extruder body 1 through the feed hopper 2.

[0031] When using this utility model, when installing the die head 6, first align and fit the second fixing plate 5 on the die head 6 with the first fixing plate 4 on the extruder body 1 to ensure that the positions of the slots 12 of the two are corresponding. Then, rotate the rotating block 8 on the U-shaped block 7 so that the threaded rod 9 is inserted into the corresponding slot 12. Next, rotate the nut 10. Since the nut 10 is threadedly connected to the threaded rod 9 and the nut 10 is rotatably connected to the fixing ring 11, when the nut 10 rotates, it will drive the fixing ring 11 to move closer to the first fixing plate 4 and the second fixing plate 5 until the fixing ring 11 is tightly pressed on the first fixing plate 4 and the second fixing plate 5, thus completing the fixing of the die head 6.

[0032] When it is necessary to replace the mold head 6, rotate the nut 10 in the opposite direction to move the retaining ring 11 away from the first retaining plate 4 and the second retaining plate 5, and then rotate the rotating block 8 to turn the threaded rod 9 out of the bayonet 12, so that the mold head 6 can be removed.

[0033] When installing the helical blade 14, first press the positioning block 17 to retract it into the groove 16, and simultaneously compress the spring 18. Then, align the rectangular groove 15 on the central shaft of the helical blade 14 with the rectangular rod 13, and place the helical blade 14 onto the rectangular rod 13. When the rectangular groove 15 and the rectangular rod 13 are fully engaged, and the positioning block 17 corresponds to the positioning hole, release the positioning block 17. Under the elastic force of the spring 18, the positioning block 17 pops out of the groove 16 and snaps into the positioning hole, completing the installation of the helical blade 14. When it is necessary to disassemble the helical blade 14, press the positioning block 17 to retract it into the groove 16, and then pull the helical blade 14 out of the rectangular rod 13 for easy cleaning, replacement, and maintenance.

[0034] During operation, the rice noodle raw material is added into the extruder body 1 through the feed hopper 2. The motor 3 is started, and the motor 3 drives the rectangular rod 13 to rotate. The rectangular rod 13 drives the spiral blade 14 to rotate through the cooperation with the rectangular groove 15. The spiral blade 14 pushes the raw material to move towards the die head 6. The raw material finally forms rice noodles through the wire outlet hole on the die head 6.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
