Then, due to the siphon principle, the gas squeezed out from the piston cylinder will suck out the edible oil in the oil tank through the connecting elbow and the one-way valve, and spray it out through the spray head. The sprayed oil mist will be sprayed on the inner wall of the mold plate, so that after the rice slurry falls into the mold plate and is pressed into rice cakes, the rice cakes are not easy to stick to the mold plate, which is more convenient for demolding the rice cakes.

[0025] The unloading mechanism includes a round can 41, which is fixedly connected between the two supporting arms 32. A feed port is opened on one side of the round can 41, and the lower part of the round can 41 is open. A sealing cover 401 is clamped at the feed port of the round can 41. A material distribution frame 42 is fixedly connected to the lower part of the round can 41. The interior of the material distribution frame 42 is communicated with the interior of the round can 41. A plurality of conduction valves 43 are fixedly connected to the lower part of the material distribution frame 42. An infrared transmitter 44 is fixedly connected to one side of the bottom plate 2. An infrared receiver 45 is fixedly connected to one side of the material distribution frame 42. The infrared receiver 45 is used to receive infrared signals and control the switch of the conduction valve 43. A baffle 46 is fixedly connected to one of the electric sliders 33. The baffle 46 is used to block the infrared transmitter 44 and the infrared receiver 45.

[0026] The cake pressing mechanism includes a limited push frame 52, which is slidably connected between the two electric sliders 33, and a tension spring 53 is connected between the limited push frame 52 and the electric slider 33. An inclined pressure rod 54 is fixedly connected to the two electric sliders 33. A mold plate 55 is placed on the bottom plate 2, and the mold plate 55 contacts the limited push frame 52. Four vertical rods 56 are fixedly connected on the side of the bottom plate 2 away from the mold plate 55, and a support frame 57 is slidably connected between the four vertical rods 56. A return spring 58 is connected between the support frame 57 and the bottom plate 2. A plurality of pressing plates 59 are fixedly connected to the lower part of the support frame 57, and side rods 510 are fixedly connected on both sides of the support frame 57. A limited bending rod 511 is fixedly connected on the side of the bottom plate 2 close to the vertical rod 56.

[0027] In actual work, the rice cake is formed by pouring the prepared rice slurry into the mold for pressing. The pressed rice cake needs to be baked and other subsequent processes. At first, there is no obstruction between the infrared transmitter 44 and the infrared receiver 45, so that the infrared receiver 45 receives the infrared signal, and the conduction valve 43 is in a closed state. The operator first removes the sealing cover 401, and then adds the prepared rice slurry to the round can 41 and the material distribution frame 42. Then the operator starts the electric slider 33, and the electric slider 33 will drive the limit push frame 52, the inclined pressure rod 54 and the mold plate 55 to move closer to the material distribution frame. The mold plate 55 moves horizontally in the direction of the pressing plate 59. After the mold plate 55 moves horizontally for a distance, the mold plate 55 is located below the material distribution frame 42, and the baffle plate 46 begins to block between the infrared transmitter 44 and the infrared receiver 45, so that the infrared receiver 45 does not receive the infrared signal, and then controls the conduction valve 43 to open, and the rice slurry flows downward, and the rice slurry falls downward into the mold plate 55 through the conduction valve 43. Then, the mold plate 55 and the inclined pressure rod 54 continue to move horizontally for a distance toward the pressing plate 59, and the baffle plate 46 no longer blocks between the infrared transmitter 44 and the infrared receiver 45, and the rice slurry stops falling. The mold plate 55 is no longer located below the material distribution frame 42. After the mold plate 55 continues to move horizontally for a distance, the inclined pressure rod 54 contacts the side rod 510, and one side of the mold plate 55 contacts the limit bending rod 511. The mold plate 55 is located directly below the pressing plate 59. Then the electric slider 33 drives the inclined pressure rod 54 to continue to move horizontally toward the side close to the limit bending rod 511. Since the mold plate 55 is blocked by the limit bending rod 511 and stops moving, the limit push frame 52 also stops moving, the tension spring 53 is stretched, and the inclined pressure rod 54 continues to move horizontally to squeeze the side rod 510 to drive the support frame 57 and the pressing plate 59 After moving downward for a certain distance, the pressing plate 59 moves downward to press the rice slurry in the mold plate 55 into rice cakes, and then the electric slider 33 drives the inclined pressure rod 54 to reset, and the pressing plate 59 resets upward, and the electric slider 33 drives the mold plate 55 and the pressed rice cakes to reset in the direction away from the limiting bent rod 511. When the electric slider 33 is reset, the operator can take out the mold plate 55 upward, take out the rice cakes inside, and then place the mold plate 55 on the bottom plate 2, and it is limited by the limiting push frame 52, so that the rice slurry can be more convenient for quantitative feeding, and the specifications of the pressed rice cakes are more uniform.

[0029] On the basis of Example 1, Figure 4-6As shown, a scraping mechanism is also included, and the scraping mechanism is arranged on the bottom plate 2.

The scraping mechanism includes two guide frames 61, and the two guide frames 61 are fixedly connected to the side of the bottom plate 2 close to the limit bending rod 511. The side of the distributing frame 42 close to the guide frame 61 is fixedly connected with a connecting rod 62, and the connecting rod 62 is connected to the two guide frames 61. The two guide frames 61 are slidably connected with a moving block 63, and the two moving blocks 63 are fixedly connected to the two guide frames 61. 3 is rotatably connected with a material pocket frame 64, an inclined scraper 641 is fixedly connected to the upper part of the material pocket frame 64, a torsion spring 65 is connected between the material pocket frame 64 and the moving block 63, swing gears 66 are fixedly connected on both sides of the material pocket frame 64, two rack straight rods 67 are fixedly connected on the side of the bottom plate 2 close to the limit bending rod 511, a waste frame 68 is slidably connected to the side of the bottom plate 2 close to the limit bending rod 511, and two magnet push plates 69 are fixedly connected to the side of the limit pushing frame 52 close to the limit bending rod 511.

[0030] When the mold plate 55 moves horizontally toward the direction close to the limit bending rod 511 together with the electric slider 33, the mold plate 55 will drive the magnet push plate 69 to move together. After the magnet push plate 69 moves horizontally for a distance, it will suck the side of the bag material frame 64 and squeeze it to drive it to move horizontally toward the direction close to the limit bending rod 511. The horizontal movement of the bag material frame 64 will drive the inclined scraper 641 to move horizontally together. The inclined scraper 641 moves horizontally toward the direction close to the limit bending rod 511 to scrape off the rice slurry that may be adhered to the bottom surface of the pressing plate 59, and the scraped rice slurry will fall into the bag material frame 64. Then, after the bag material frame 64 continues to move horizontally for a distance, the inclined scraper 641 completes the scraping of the rice slurry on the bottom surface of the pressing plate 59, and then the swing gear 66 will cooperate with the rack straight rod 67 is engaged, and as the pocket material frame 64 continues to move horizontally, the swing gear 66 will drive the pocket material frame 64 to swing downward, the torsion spring 65 is twisted, and the pocket material frame 64 swings downward to pour the scraped rice slurry into the waste frame 68, and then the operator can take out the waste frame 68 horizontally for cleaning, so that the rice slurry on the bottom surface of the pressing plate 59 is scraped off each time the rice cake is pressed, which can prevent the rice slurry from adhering to the bottom surface of the pressing plate 59 for a long time and deteriorating, thereby making the pressing plate 59 not easily contaminated, thereby improving the safety of the pressed rice cakes, after the pocket material frame 64 is reset for a distance together with the magnet push plate 69 and the electric slider 33, the moving block 63 will be stuck by the guide frame 61 and stop moving, and the magnet push plate 69 will be out of contact with the pocket material frame 64.

[0031] Example 3

[0032] On the basis of Example 2, Figure 7-8As shown, an anti-sticking mechanism is also included, and the anti-sticking mechanism is arranged on the bottom plate 2. The anti-sticking mechanism is used to facilitate the demoulding of the successfully pressed rice cakes. The anti-sticking mechanism includes two bent hanging rods 71, and the two bent hanging rods 71 ​​are fixedly connected to the bottom plate 2. A sliding push rod 72 is slidably connected between the two bent hanging rods 71, and a supporting spring 73 is connected between the sliding push rod 72 and the bent hanging rod 71. A branch pipe frame 74 is fixedly connected between the lower parts of the two bent hanging rods 71, and a plurality of spray heads 75 are fixedly connected to the lower part of the branch pipe frame 74. 74 is hollow, and a piston cylinder 76 is fixedly connected to the upper part of the branch rack 74.

Bending rods 710 are fixedly connected to both sides of the sliding push rod 72, and a plurality of inclined plane frames 711 are provided on both sides of the limiting push rack 52.

[0033] At first, the operator adds a certain amount of edible oil into the oil tank 77. When the mold plate 55 moves toward the direction close to the limit bending rod 511, the mold plate 55 and the limit push frame 52 drive the inclined frame 711 to move horizontally together. Then, after the inclined frame 711 moves a certain distance, it will contact the curved rod 710 and squeeze the curved rod 710 to move downward for a certain distance. The downward movement of the curved rod 710 will drive the sliding push rod 72 to move downward for a certain distance. The support spring 73 is stretched, and the sliding push rod 72 moves downward. The movement will drive the gas in the piston cylinder 76 into the branch frame 74 and spray it out through the spray head 75 below the branch frame 74. Then, due to the siphon principle, the gas squeezed out from the piston cylinder 76 will suck the edible oil in the oil tank 77 through the connecting elbow 79 and the one-way valve 78, and spray it out in atomization through the spray head 75. The sprayed oil mist will be sprayed on the inner wall of the mold plate 55. In this way, after the rice slurry falls into the mold plate 55 and is pressed into rice cakes, the rice cakes are not easy to stick to the mold plate 55, which makes it easier to demould the rice cakes.
