Description

Technical Field

[0001] The present application relates to the technical field of rice cake processing equipment, and more specifically, to a rice cake extrusion molding equipment. Background Art

[0002] Rice cake has developed into a snack available all year round on the market, with different flavors in the north and south. The shape of the rice cake is generally defined by the mold at the end of the extrusion equipment. When making oblong rice cakes, a mold in the shape of an oblong hole is used. However, when the rice cake is extruded out of the mold, there will be uneven force on both sides and in the middle of the rice cake extrusion hole, which makes the rice cake extrusion rate in the middle of the hole inconsistent with the rate on both sides of the hole, resulting in inconsistent thickness of the extruded rice cake, thick in the middle and thin on both sides, unsightly style, and unable to achieve the shape required by customers; rice cake molds need to be replaced and cleaned frequently, and rice cake molds of different sizes need to be produced according to customer needs. The existing rice cake extrusion molding equipment has the problem that the rice cake mold is not easy to replace and clean, which in turn affects production efficiency. Utility Model Content

[0003] The utility model provides a rice cake extrusion molding device. By designing a rice cake extrusion hole to be wider on both sides than in the middle, the problem of inconsistent extrusion rates of the rice cake in the middle and on both sides of the hole is solved, resulting in inconsistent thickness of the extruded rice cakes, thick in the middle and thin on both sides, unsightly style and unable to achieve the shape required by customers; the problem of inconvenient replacement and cleaning of the rice cake mold is solved through the cooperation of the thread at the discharge port and the circular locking block.

[0004] The utility model is realized through the following technical solutions.

[0005] A rice cake extrusion molding device comprises: a feed port arranged on the top of a shell body, two screw conveying shafts are arranged below the feed port, one end of the screw conveying shaft is connected to the power output end of a motor, the other end of the screw conveying shaft extends into a discharge port, and the discharge port is connected to a rice cake mold.

[0006] The rice cake mould comprises a fixed frame which is fixedly connected to a rice cake extrusion hole via a pre-pressing cavity; the rice cake extrusion hole is an oblong hole, and the arc diameters on both sides of the oblong hole are 1.2 to 1.5 times the width of the rectangle.

[0007] By widening the two sides of the rice cake extrusion hole, the extrusion rate on both sides of the extrusion hole is equal to the rate in the middle when extruding the oblong rice cake, thereby preventing the uneven thickness of the extruded oblong rice cake from failing to meet customer needs.

[0008] In a further technical solution, in order to facilitate the replacement and cleaning of the rice cake mold, screws are provided on both sides of the discharge port, connecting plates are fixedly provided on both sides of the discharge port, the screws are hinged to the connecting plates, grooves are provided on both sides of the corresponding fixed frame, and a circular locking block is provided on the screw, which is connected to the screw through a thread.

[0009] Put the bolt into the corresponding groove on the fixed frame, then turn the circular locking block on the screw, tighten the circular locking block to fix the rice cake mold to the discharge port of the extrusion equipment. When disassembling, turn the circular locking block in the opposite direction to remove the rice cake mold.

[0010] Furthermore, in order to ensure the sealing between the rice cake mould and the material discharge port of the equipment, a sealing ring is fixedly provided on the fixed frame.

[0011] Furthermore, in order to evenly distribute the rice cakes in the pre-pressing chamber, the pre-pressing chamber is configured as a tapered slope that gradually decreases in size along the discharge direction.

[0012] The material is transported to the pre-pressing chamber by the screw conveying shaft, and then the rice cake is evenly distributed in the pre-pressing chamber through the tapered inclined surface that changes from large to small, and then evenly extruded from the rice cake extrusion hole.

[0013] Furthermore, in order to ensure that the rice cake mould and the discharge port of the extrusion equipment are fixed more stably, a circular groove embedded with the circular locking block is provided on the groove of the fixing frame.

[0014] The circular locking block on the screw is screwed into the circular groove, which further ensures the stable connection between the rice cake mold and the discharge port of the extrusion equipment.

[0015] Furthermore, in order to facilitate the operator to rotate the circular locking block, an auxiliary plate for facilitating the twisting of the circular locking block is provided on the circular locking block.

[0016] The technical effects of the utility model are:

[0017] The present application designs the rice cake extrusion hole to be wider on both sides than in the middle, thereby ensuring that the extrusion rates on both sides of the extrusion hole are equal to the rate in the middle when extruding oblong rice cakes, so that the thickness of the extruded oblong rice cakes is uniform, meeting customer needs; through the cooperation of the thread at the discharge port and the circular locking block, it is convenient for staff to replace and clean the rice cake mold, thereby improving production efficiency.

[0025] During the implementation process, the motor 4 is started, and the power output end of the motor 4 drives the spiral conveying shaft 3 to rotate, and the rice cake to be extruded is put in from the feed port 2, and the rice cake is transported to the discharge port 5 through the spiral conveying shaft 3. The rice cake enters the pre-pressing cavity 603 of the rice cake mold 6 through the discharge port 5, and then the rice cake is evenly distributed in the pre-pressing cavity 603 through the tapered inclined surface that changes from large to small, and then it is evenly extruded from the rice cake extrusion hole 602. In order to make the thickness of the extruded rice cake uniform, the arc diameters on both sides of the oblong hole of the rice cake extrusion hole 602 are 1.2 to 1.5 times the width of the rectangle to prevent uneven force on both sides and the middle of the rice cake extrusion hole 602 during the extrusion process, so that the extrusion rate of the rice cake in the middle of the hole is inconsistent with the rate on both sides of the hole, resulting in uneven thickness of the extruded rice cake. Example

[0027] During the implementation process, when installing the rice cake mold 6, the screws 7 provided on both sides of the discharge port 5 are rotated into the grooves 10 of the fixed frame 601, and then the circular locking block 9 on the screw 7 is rotated, and the circular locking block 9 is turned into the circular groove 12 and tightened. The rice cake mold 6 can be installed on the discharge port 5 of the extrusion equipment. The circular locking block 9 is stuck in the circular groove 12 to ensure the stable connection between the rice cake mold 6 and the discharge port 5, and prevent the screw 7 from slipping out of the groove 10. When the rice cake mold 6 needs to be removed, it is only necessary to twist the circular locking block 9, turn the circular locking block 9 out of the circular groove 12, and then turn the screw 7 and the circular locking block 9 out of the groove 10 to remove the rice cake mold 6. Example

[0028] Combination Figure 3 A sealing ring 11 is fixedly arranged on the fixed frame 601, and an auxiliary plate 13 is arranged on the circular locking block 9 for facilitating the twisting of the circular locking block 9.
