[0002] An extruder for rice cake processing is a device used to process rice flour or other suitable raw materials for making rice cakes through a high-temperature, high-pressure, and high-speed extrusion process, turning them into shaped rice cakes. This equipment is commonly used to shape steamed rice flour or other raw materials into rice cakes of specific shapes and sizes, and is widely used in the mass production of rice cakes.
[0003] Existing extruders for rice cake processing use auger blades to extrude the rice cake raw materials. However, after use, the auger blades are inside the cylinder, making cleaning difficult and costly. Utility Model Content
[0004] The purpose of this utility model is to provide an extruder for rice cake processing, so as to solve the problem mentioned in the background art that the auger blades of the rice cake processing extruder are difficult to clean and have high cleaning costs after use because they are inside the cylinder.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an extruder for processing rice cakes, comprising a base, a cylinder fixedly connected to the surface of the base, a feed hopper fixedly connected to the surface of the cylinder, a fixing block fixedly connected to the surface of the base, a motor B fixedly connected to the surface of the fixing block, a lead screw fixedly connected to the output shaft of the motor B, a square nut threadedly connected to the surface of the lead screw, a cylinder cover fixedly connected to the surface of the square nut, a motor A fixedly connected to the surface of the cylinder cover, a rotating shaft fixedly connected to the output shaft of the motor A, auger blades fixedly connected to the surface of the rotating shaft, a piston plate rotatably connected to the end of the rotating shaft away from the cylinder cover, a fixing nut fixedly connected to the surface of the cylinder, and a limiting bolt A threadedly connected to the surface of the fixing nut.
[0006] Preferably, a replacement mechanism is provided on the surface of the piston plate. The replacement mechanism includes a turntable, which is rotatably connected to the surface of the piston plate. A movable tube is slidably connected to the surface of the turntable. An extrusion head is fixedly connected to one end of the movable tube, and a rubber ring is fixedly connected to the other end of the movable tube. A spring is fixedly connected to the surface of the turntable, and a connecting rod is fixedly connected to the surface of the cylinder. A limit bolt B is threadedly connected to the surface of the connecting rod.
[0007] Preferably, the diameter of the cylinder cover and piston plate is the same as the inner diameter of the cylinder body. The cylinder cover and piston plate slide on the inner surface of the base. The cylinder cover and piston plate are located at both ends of the cylinder body. The motor A drives the rotating shaft and auger blades to rotate inside the cylinder body through the output shaft.
[0008] Preferably, the motor B drives the lead screw to rotate on the fixed block via the output shaft. During the rotation, the lead screw drives the square nut to slide on the surface of the base, and the square nut drives the cylinder cover to slide synchronously on the base.
[0009] Preferably, the piston plate always slides on the inner surface of the cylinder, and a limiting groove is formed on the side of the piston plate. The limiting bolt A is inserted into the limiting groove of the piston plate by a fixing nut.
[0010] Preferably, multiple sets of movable tubes are provided and evenly distributed on the surface of the turntable. The end of the spring away from the turntable is fixedly connected to the limiting plate, and the elastic force of the spring acts on the movable tube and the extrusion head through the limiting plate.
[0011] Preferably, the piston plate has an extrusion hole on its surface, the rubber ring is flared, the movable tube is inserted into the extrusion hole of the piston plate, the movable tube squeezes the rubber ring in the extrusion hole of the piston plate, the connecting rod has a threaded hole on its surface, the limiting bolt B is threaded into the threaded hole of the connecting rod, and the limiting bolt B is connected to the surface of the limiting plate through the connecting rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. When the auger blades of this extruder need to be cleaned, the upper limit bolt A of the fixing nut is rotated to remove the restriction of the piston plate by the upper limit bolt A. Then, the output shaft of the motor B drives the lead screw to rotate. The lead screw drives the square nut to slide on the base. The square nut drives the cylinder cover to slide away from the base. The cylinder cover drives the piston plate to slide on the inner surface of the cylinder through the rotating shaft until the piston plate slides from one end of the cylinder to the other end. At this time, the rotating shaft and the auger blades are completely separated from the inside of the cylinder, which makes it convenient for manual cleaning of the auger blades, greatly reducing the difficulty of manual cleaning of the auger blades and also reducing the labor cost of cleaning the auger blades.
[0014] 2. This extruder rotates a turntable on the surface of the piston plate, changing the relative position of the movable tube. The required extrusion head is moved to a line parallel to the extrusion hole of the piston plate. The spring force acts on the movable tube and the extrusion head through the limiting plate, causing the movable tube to insert into the extrusion hole of the piston plate. The movable tube compresses the rubber ring on the extrusion hole of the piston plate to form a seal. The limiting bolt B is rotated through the connecting rod to contact the limiting plate, thereby limiting the position of the movable tube and the extrusion head through the limiting plate, thus completing the replacement of the extrusion head. This makes the replacement of the extrusion head simple and convenient, and greatly saves the time of replacing the extrusion head. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 One embodiment provided by this utility model:
[0023] An extruder for processing rice cakes includes a base 1, a cylinder 11 fixedly connected to the surface of the base 1, a feed hopper 12 fixedly connected to the surface of the cylinder 11 for placing rice cake raw materials into the cylinder 11, a fixing block 25 fixedly connected to the surface of the base 1, a motor B26 fixedly connected to the surface of the fixing block 25, a lead screw 27 fixedly connected to the output shaft of the motor B26, a square nut 28 threadedly connected to the surface of the lead screw 27, a cylinder cover 2 fixedly connected to the surface of the square nut 28, and a motor A21 fixedly connected to the surface of the cylinder cover 2. A rotating shaft 22 is fixedly connected to the output shaft of the extruder 1. An auger blade 23 is fixedly connected to the surface of the rotating shaft 22. A piston plate 24 is rotatably connected to the end of the rotating shaft 22 away from the cylinder cover 2. A fixing nut 29 is fixedly connected to the surface of the cylinder 11. A limiting bolt A210 is threadedly connected to the surface of the fixing nut 29. When cleaning the auger blade 23, the extruder can slide the auger blade 23 out from the inner surface of the cylinder 11, which makes it convenient for manual cleaning of the auger blade 23, greatly reducing the difficulty of manual cleaning of the auger blade 23 and also reducing the labor cost of cleaning the auger blade 23.
[0024] Furthermore, a replacement mechanism is provided on the surface of the piston plate 24. The replacement mechanism includes a turntable 3, which is rotatably connected to the surface of the piston plate 24. A movable tube 31 is slidably connected to the surface of the turntable 3. One end of the movable tube 31 is fixedly connected to an extrusion head 34, and the other end of the movable tube 31 is fixedly connected to a rubber ring 35. A spring 32 is fixedly connected to the surface of the turntable 3, and a connecting rod 36 is fixedly connected to the surface of the cylinder 11. A limit bolt B37 is threadedly connected to the surface of the connecting rod 36. The replacement mechanism can replace the extrusion head 34 on the piston plate 24. The operation is simple and convenient, and it greatly saves the time of replacing the extrusion head 34.
[0025] Furthermore, the diameters of the cylinder cover 2 and piston plate 24 are the same as the inner diameter of the cylinder 11. The cylinder cover 2 and piston plate 24 slide on the inner surface of the base 1. The cylinder cover 2 and piston plate 24 are located at both ends of the cylinder 11 respectively. The cylinder cover 2 and piston plate 24 can make the two ends of the cylinder 11 closed, which facilitates the transportation and extrusion of the rice cake raw materials inside the cylinder 11. The motor A21 drives the rotating shaft 22 and the auger blade 23 to rotate inside the cylinder 11 through the output shaft. During the rotation, the auger blade 23 continuously outputs the rice cake raw materials from one end of the piston plate 24.
[0026] Furthermore, motor B26 drives lead screw 27 to rotate on fixed block 25 via output shaft. During rotation, lead screw 27 drives square nut 28 to slide on the surface of base 1. Square nut 28 drives cylinder cover 2 to slide synchronously on base 1. Cylinder cover 2 will slide to one end of cylinder 11, and cylinder cover 2 will drive piston plate 24 to slide on cylinder 11 via rotating shaft 22.
[0027] Furthermore, the piston plate 24 always slides on the inner surface of the cylinder 11, ensuring the stability of the cylinder cover 2, the rotating shaft 22 and the auger blade 23 on the cylinder 11. A limit groove is opened on the side of the piston plate 24, and the limit bolt A210 is inserted into the limit groove of the piston plate 24 through the fixing nut 29. The limit bolt A210 restricts the rotation of the piston plate 24 on the cylinder 11, thereby locking the position of the piston plate 24 on the cylinder 11, so that the rotating shaft 22 and the auger blade 23 can rotate stably inside the base 1.
[0028] Furthermore, multiple sets of movable tubes 31 are provided. The relative positional relationship between multiple sets of movable tubes 31 can be changed by rotating the turntable 3. They are evenly distributed on the surface of the turntable 3. The end of the spring 32 away from the turntable 3 is fixedly connected to the limiting plate 33. The elastic force of the spring 32 acts on the movable tube 31 and the extrusion head 34 through the limiting plate 33. The movable tube 31 will contact and connect to the surface of the piston plate 24.
[0029] Furthermore, an extrusion hole is provided on the surface of the piston plate 24, the rubber ring 35 is in the shape of a trumpet, and the movable tube 31 is inserted into the extrusion hole of the piston plate 24. The rice cake raw material will enter the movable tube 31 through the extrusion hole of the piston plate 24, and the movable tube 31 will then output the rice cake raw material through the extrusion head 34. The movable tube 31 squeezes the rubber ring 35 on the extrusion hole of the piston plate 24, so that a seal is formed between the movable tube 31 and the piston plate 24. A threaded hole is provided on the surface of the connecting rod 36, and the limiting bolt B37 is threadedly connected to the threaded hole of the connecting rod 36. The limiting bolt B37 is connected to the surface of the limiting plate 33 through the connecting rod 36. The limiting bolt B37 restricts the position of the movable tube 31 on the turntable 3 through the limiting plate 33, so that the extrusion head 34 can stably extrude the rice cake raw material.
[0030] Working principle: When the auger blades 23 need to be cleaned, the upper limit bolt A210 of the fixing nut 29 is rotated to remove the restriction of the piston plate 24 by the upper limit bolt A210. Then, the output shaft of the motor B26 drives the lead screw 27 to rotate. The lead screw 27 drives the square nut 28 to slide on the base 1 by rotating. The square nut 28 drives the cylinder cover 2 to slide away from the base 1. The cylinder cover 2 drives the piston plate 24 to slide on the inner surface of the cylinder 11 through the rotating shaft 22 until the piston plate 24 slides from one end of the cylinder 11 to the other end. At this time, the rotating shaft 22 and the auger blades 23 are completely separated from the inside of the cylinder 11, which makes it convenient for manual cleaning of the auger blades 23, greatly reducing the difficulty of manual cleaning of the auger blades 23 and also reducing the labor cost of cleaning the auger blades 23.
[0031] Rotate the turntable 3 on the surface of the piston plate 24 to change the relative position of the movable tube 31. Move the required extrusion head 34 to the parallel line of the extrusion hole of the piston plate 24. The elastic force of the spring 32 acts on the movable tube 31 and the extrusion head 34 through the limiting plate 33, so that the movable tube 31 is inserted into the extrusion hole of the piston plate 24. The movable tube 31 squeezes the rubber ring 35 on the extrusion hole of the piston plate 24 to form a seal. Rotate the limiting bolt B37 to contact the limiting plate 33 through the connecting rod 36, thereby limiting the position of the movable tube 31 and the extrusion head 34 through the limiting plate 33, thus completing the replacement of the extrusion head 34. This makes the replacement of the extrusion head 34 simple and convenient, and greatly saves the time of replacing the extrusion head 34.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
