  This invention is mainly used for molding kneaded food doughs such as rice cakes, dumplings, bean jam, confectionery, etc., which are highly sticky. The present invention relates to a dough extrusion ring, and allows the dough to be accurately cut and separated.

  A technology that cuts a fixed amount with a cutter that rotates while approaching the outside of the extrusion port while extruding the kneaded food dough from the extrusion port part of the extrusion cylinder by connecting and driving the extrusion helix to the spiral drive shaft In addition, there is known a technique (for example, see Patent Document 1) in which a metal pipe and a synthetic resin mouth ring are detachably attached to the metal pipe at the extrusion port portion of the extrusion cylinder.

Japanese Examined Patent Publication No. 63-48508 (first page, FIG. 1).

  A form in which the extruded dough is cut by a certain amount while continuously extruding kneaded foods such as rice cake and rice cake from the extrusion port by rotation of the extrusion spiral and rotating the cutter close to the extrusion port Then, the dough cut at this extrusion port part contacts or adheres to the outer peripheral surface of the resin port ring outside the extrusion port in the middle of dropping, or the falling timing of the dough for each cutting separation is disturbed once. The doughs after being separated are bonded to each other and easily become a dumpling state, and it is difficult to maintain an accurate separation-independent molding form.

  The invention according to claim 1 is provided with a tube base 4 for forming an extrusion port chamber 3 in which an inner peripheral surface is reduced in diameter over a portion of a front end of a cylindrical port 2 on an extrusion tube 1 for extruding and forming a dough by rotation of an extrusion spiral. The non-adhesive Teflon resin material allows the fitting cylinder rib 5 to be fitted into the cylinder port 2 from the front side, the extrusion port 6 having a smaller diameter than the cylinder port 2, and the diameter larger than the fitting cylinder rib 5. A mounting rib 8 that can be formed and joined to the front end surface 7 of the tube base 4 and can be fixed by fixing, and protrudes over the front end edge 9 of the extrusion port 6 on the front side of the mounting rib 8 so as to slide the cutting operation of the cutter 10. A Teflon resin port ring 15 in which a cutting interval 14 is formed between the front surface 12 of the joining rib 8 and the outer peripheral surface 13 of the cutting rib ring 11 is integrally formed with the cutting rib ring 11 and the like. Removable by fitting into the front end of the gold 4 The mounting has a structure of the dough extrusion rings kneading made food processing machine according to claim.

  By supplying the kneaded food dough to the inside of the extrusion cylinder 1 and driving and rotating the extrusion spiral, the supply dough in the extrusion cylinder 1 is maintained at a constant pressure in the extrusion port chamber 3 of the cylinder mouthpiece 4 and forced. Extrude. The dough is extruded while being swirled in the extrusion port chamber 3 by the extrusion pressure of the dough, and is further pushed out from the front edge 9 to the front side through the extrusion port 6 in the Teflon resin port ring 15. A cutter 10 is rotated on the front side of the extrusion port 6 of the Teflon resin port ring 15, and is cut off every time the cutter 10 rotates in sliding contact with the front end edge 9 of the extrusion port 6. The fabric cut by this cutter is separated from the front end face 9 of the cutting ridge ring 11 and dropped, but at this time, a cutting interval 14 is formed below the front end edge 9. The material to be cut off is difficult to contact and adhere to the front surface 12 of the mounting rib 8 and the like, and since there is no cut-off resistance member, it is cut and immediately dropped by the rotation of the cutter.

  In the first aspect of the present invention, as described above, the Teflon resin port ring 15 is an expensive one made of a Teflon resin material which is a non-adhesive resin material, but has an extrusion port 6 and is relatively A ring plate having a thin thickness as a main body, cutting rib rings 11 and fitting cylindrical ribs 5 are formed at the front and rear ends of the cylindrical portion where the extrusion port 6 is formed, and mounting ribs 8 are formed at the outer peripheral portion. In order to make it thin and small enough to fit into the tube mouth 2 of the tube cap 4, the diameter of the extrusion port 6, the thickness of the cutting projection ring 11, etc. It can be easily and freely formed by processing or the like according to use, and can meet various specifications. The Teflon resin port ring 15 can be easily replaced, and an inexpensive configuration can be obtained. The front end edge 9 of the cutting rib ring 11 of the Teflon resin port ring 15 is subjected to cutting action resistance by the cutter 10, but the fitting tube rib 5 is fitted and held in the tube port 2 of the tube base 4. Since the protruding amount from 2 to the front side is short, a stable mounting state can be maintained. Further, the cutting action resistance can absorb distortion, resistance impact and the like by the elasticity of the cutting ridge ring 11, and the cutting action can be smoothly performed by reducing wear and damage of the cutter 10. Moreover, by forming the extrusion port 6 by the Teflon resin port ring 15, forming the front end edge 9 of the cutting ridge ring 11, the cutting interval 14, etc., the extrusion dough is extruded in the extrusion port chamber 3 of the tube base 4. The swirling and extruding action of the dough can be smoothly performed, and when the cocoon dough is cut off, the cut dough is prevented from being disturbed by preventing adhesion between the cut doughs and the cut ridge ring 11 or the like. It is possible to form the koji dough accurately and smoothly.

  Based on the drawing, the kneaded food processing machine rotates along the outer edge of the extrusion port 6 while extruding the dough of the kneaded food supplied into the extrusion cylinder 1 from the extrusion port 6 by the rotation of the extrusion spiral 16. The cutter 10 is cut and separated every predetermined amount. A box-shaped machine base 17, a transmission case 18 mounted on the machine base 17, an extrusion cylinder 1 having an extrusion spiral 16 for extruding a dough fed from an upper hopper 19, and the extrusion cylinder 1 A cutter 10 or the like that cuts and separates the dough extruded from the front end extrusion port 6 by a predetermined amount is disposed. In the machine base 17, there are an electric geared motor 20 for interlocking rotation of the extrusion spiral 16, an electric motor 21 for interlocking rotation of the inverter 26 and the cutter 10, and an electromagnetic clutch that stops at a fixed position for each rotation. A cutter clutch 22 and the like are arranged. Further, the transmission case 18 is provided with a spiral drive shaft 23 for driving the extrusion spiral 16, and an interlocking sprocket 24, a chain 25, and the like of the spiral drive shaft 23 are internally provided. An extrusion spiral 16 is horizontally supported on the extrusion cylinder 1, and a dough extrusion port 6 having a predetermined shape is formed at the front end of the extrusion spiral 16.

  Here, the structure of the dough extrusion ring is such that a tube cap for forming an extrusion port chamber 3 in which the inner peripheral surface is reduced in diameter over two portions of the front end of the tube 1 is formed by extruding and forming the koji dough by rotation of the extrusion spiral. 4, a fitting cylinder rib 5 fitted into the inside of the cylinder port 2 from the front side by a non-adhesive Teflon resin material, an extrusion port 6 having a smaller diameter than the cylinder port 2, and the fitting cylinder rib 5 A mounting rib 8 which is formed to have a large diameter and can be attached and fixed to the front end surface 7 of the tube base 4, and protrudes over the front end edge 9 of the extrusion port 6 on the front side of the mounting rib 8 to cut the cutter 10. A Teflon resin mouth ring 15 having a cut interval 14 formed between the front surface 12 of the joining rib 8 and the outer peripheral surface 13 of the cutting rib ring 11 is formed integrally with the cutting rib ring 11 to be slidably contacted. The front end tube opening 2 of the tube cap 4 It is fitted to attach detachably to.

  By supplying the kneaded food dough to the inside of the extrusion cylinder 1 and driving and rotating the extrusion spiral, the supply dough in the extrusion cylinder 1 is maintained at a constant pressure in the extrusion port chamber 3 of the cylinder mouthpiece 4 and forced. Extrude. The dough is extruded while being swirled in the extrusion port chamber 3 by the extrusion pressure of the dough, and is further pushed out from the front edge 9 to the front side through the extrusion port 6 in the Teflon resin port ring 15. A cutter 10 is rotated on the front side of the extrusion port 6 of the Teflon resin port ring 15, and is cut off every time the cutter 10 rotates in sliding contact with the front end edge 9 of the extrusion port 6. The fabric cut by this cutter is dropped from the front end edge 9 of the cutting ridge ring 11. At this time, a cut interval 14 is formed on the lower side of the front end edge 9. Since it is difficult to contact the front surface 12 of the mounting rib 8 and there is no cutting resistance member, it is cut and immediately dropped by the rotation of the cutter 10.

  The geared motor 20 is transmitted via an inverter 26 and transmits and rotates the extrusion spiral 16. By the rotation of the extrusion spiral 16, the supply dough in the extrusion cylinder 1 is forcedly extruded from the extrusion port 6 while maintaining a constant pressure. The extrusion pressure of the dough is controlled by the inverter 26 to rotate the geared motor 20, and is controlled and maintained at a substantially constant pressure regardless of changes in the hardness, softness, etc. of the dough. Keep in quantity. Further, when changing and adjusting the extrusion amount of the dough, by adjusting the output by the inverter 26, the rotation speed of the extrusion spiral 16 by the geared motor 20 is changed steplessly, and the extrusion amount of the dough is reduced to a small range. It can be changed and adjusted in a stepless manner over a wide range from large to large. Thus, the helical drive shaft 23 is rotated by the geared motor 20 that is electrically driven through the inverter 26, and the extrusion spiral 16 connected to the drive shaft 23 is forcibly driven so as to maintain the dough extrusion pressure constant. The spiral drive shaft 23 has a shaft end 27 protruding toward the side of the extrusion cylinder 1 where the extrusion spiral 16 rotates, and a connecting socket 28 on the rear end surface of the extrusion spiral 16 is connected to the shaft end 27 with respect to the shaft end. By being engaged with the portion 27, they are connected and rotated together.

  The geared motor 20 is electrically driven through an inverter circuit in an inverter 26 case attached to the outer wall portion of the machine base 17. By the frequency conversion control by the inverter 26, the load control for driving and rotating so as to maintain the extrusion pressure of the extrusion spiral 16 at a set constant pressure is performed. An extrusion amount adjustment dial 29 for adjusting the set value of the dough extrusion pressure to change the extrusion amount or the extrusion efficiency is provided on the outer surface of the machine base 17, and the inverter is adjusted by rotating the adjustment dial 29. The output voltage by the frequency conversion of 26 is adjusted to change and adjust the rotation speed of the geared motor 20. Further, an adjustment dial 29 for the extrusion amount is provided on the outer surface of the machine base 17, and a power switch 30 for an electric circuit such as each motor 20, 21 or the like, a geared motor 20, and an electric motor 21 for the cutter 10 are provided. A motor switch 31 that is turned on and off, a cutter switch 32 that turns on and off the electromagnetic clutch 22 of the cutter 10, and the like are disposed. The geared motor 20 and the upper spiral drive shaft 23 are linked with a chain 25.

  On the front side of the front wall portion 34 of the transmission case 18, an extrusion spiral 16 is connected to the spiral drive shaft 23, and a rear end edge of the extrusion cylinder 1 that accommodates these extrusion spirals 16 is joined. It is configured to be detachable by being fitted to a stat bolt 35 and tightened with a nut 36. The shaft end portion 27 of each helical drive shaft 23 has a drive pin, and the push groove 16 can be transmitted and rotated by engaging the pin groove of the socket 28 with the drive pin. When the extrusion spiral 16 is removed, it is simply pulled out to the front side. The extrusion spiral 16 is formed in the form of double spiral blades 37 and 38 having a rotational phase difference of 180 degrees with respect to the spiral axis, and maintains a strong dough pushing force under a low-speed rotational drive.

  The front end portion of the extrusion spiral 16 is set as a free end at substantially the same position as the front end portion of the extrusion cylinder 1. A ring holder 48 that supports a point ring 33 that is located in the extrusion port chamber 3 and exerts an extrusion resistance on the central portion of the extruded dough is overlapped and fitted to the front end of the extrusion cylinder 1. The flange 41 of the tube base 4 is overlapped, and the attachment ring 39 is fitted from the outer peripheral side of the tube base 4 so as to be detachable. The flange portion 42 on the outer periphery of the front end of the extruded cylinder 1 is provided with a cylinder base 4 having a flange 41 in which a fastening pin 40 is disposed at a trisecting position and a pin hole is formed to be fitted to the fastening pin 40. Then, the polymerization is carried out from the front end portion of the extruded cylinder 1. The mounting ring 39 is fitted to the outer periphery of the tube base 4, the pin holes 44 of the mounting ring 39 are fitted to the fastening pins 40, and each pin hole 44 is rotated by the handle 43. The fastening pin 40 is guided to the back side of the flange 41, and the flange 41 is sandwiched between the flange portion 42 and the attachment ring 39, so that the attachment position of the tube cap 4 can be fixed. When removing the tube cap 4, a handle operation in the opposite direction to the above is performed.

  The tube cap 4 forms an extrusion port chamber 3 whose inner peripheral surface is hemispherical, and a tube port 2 in the front-rear direction is formed at the center of the front end. The tube cap 4, the extrusion spiral 16, the point ring 33, the extrusion tube 1, and the like are formed of aluminum or the like, and the peripheral surface is Teflon processed. A fitting tube rib 5 of the Teflon resin port ring 15 is fitted and attached to the tube port 2 of the tube cap 4 from the front side. A screw hole 46 is formed in the mounting rib 8 portion of the Teflon resin port ring 15 and the front end surface 7 of the tube base 4, and this mounting rib 8 is superposed on the front end surface 7 of the tube base 4 to form a screw hole. The countersunk 47 can be inserted into and removed from the overlapping portion 46 by being screwed.

  The Teflon resin mouth ring 15 is formed of a Teflon resin material. This Teflon resin material is made of 4-fluorinated fluororesin (polytetrafluoroethylene = PTFE), etc., and has characteristics such as non-adhesiveness, self-lubricating heat resistance, weather resistance, chemical resistance, and low friction coefficient. It is what has. Such a Teflon resin material has a diameter C (for example, C = 65 mm) of substantially the mounting rib 8 part and a thickness B (for example, B = 13 to 15 mm) extending from the fitting cylindrical rib 5 to the cutting protrusion ring 11. In this Teflon resin material, a hole for the extrusion port 6 having a diameter D (for example, D = 20 to 40 mm) can be appropriately formed in the Teflon resin material. The outer peripheral portion of the material is cut to remove 14 parts before and after the mounting rib 8 and 45 parts of the fitting interval, thereby forming the extrusion port 6 having a size suitable for forming the dough. In addition, it is possible to form the cut ridge ring 11 having a predetermined thickness or a protruding width, the fitting cylindrical rib 8, etc. In particular, the thickness of the front end edge 9 of the cut ridge ring 11 is made as thin as possible. The distance between the front edge 9 and the front surface 12 of the mounting rib 8 is As Ku formed, it can be formed so as to cut deeply as possible the direction in which the cutter 10 passes, i.e. the Setsu落 spacing 14 of the extrusion port 6 lower.

  The cutter 10 is positioned in the lateral direction of the extrusion port 6 and is supported on the machine base 17 and rotated around the cutter shaft 50 to rotate the front edge 9 of the extrusion port 6 downward from above. The dough extruded from the extrusion port 6 is cut into a predetermined thickness or length. On the front side of the extrusion port 6, a fabric sensor 51 in the form of a proximity sensor that detects the approach of the fabric extruded from the extrusion port 6 is provided, and the fabric sensor 51 detects the extrusion amount of the fabric, The clutch 22 of the cutter 10 is linked, and the cutter 10 is rotated once to cut the extruded dough into a predetermined amount. When the amount of extrusion is adjusted or changed between large and small, it is performed by moving the fabric sensor 51 back and forth with respect to the extrusion port 6 so as to approach or separate it. The cutter shaft 50 is interlocked with the chain 52 through the cutter clutch 22 by the rotation of the motor 21. When the switch by the cloth sensor 51 is turned on, the cutter stopped at a fixed position every time the cutter clutch 21 is linked. 10 is rotated once and the dough extruded from the extrusion port 6 is cut off.

  When the power switch 30 is turned on and the motor switch 31 is turned on, the geared motor 20 and the motor 21 are transmitted via the inverter 26. Here, when the dial 29 is operated to set the extrusion amount by the extrusion spiral 16 to the target position, and when the extruded dough for forming the round eyelid A is cut to a certain size, these cut thicknesses are used. The cloth sensor 51 can be set at a target position corresponding to the sheath and length. A set bolt 53 is provided at an attachment portion of the cutter 10 with respect to the cutter shaft 50, and the cutter 10 is moved and adjusted forward and backward by operation of the set bolt 53 and fixed. When the food dough for processing is supplied to the hopper 19, the inside of the extrusion cylinder 1 is moved to the extrusion port 6 at the front end by the rotation of the extrusion spiral 16 driven by the geared motor 20 via a transmission mechanism such as the spiral drive shaft 23. It is pushed toward the front and is pushed and swung in the extrusion port chamber 3 on the front side of the extrusion spiral 16 so as to be pushed forward from the extrusion port 6 of the Teflon resin port ring 15. The extrusion resistance force in the extrusion spiral 16 varies depending on the kind of the dough, hardness, softness, viscosity, etc., or may change during the extrusion of the dough. Is controlled to be substantially constant by the action of the inverter 26. For this reason, although the extrusion speed or the extrusion amount of the dough extruded from the extrusion port 6 is maintained at a preset value, the dough is extruded from the extrusion port 6 in this way, and the extrusion dough amount is reduced. When the predetermined amount is reached, this is detected by the dough sensor 51, the cutter clutch 22 is engaged, the cutter 10 is rotated once and cut from the front edge 9 of the extrusion port 6 to be separated into an accurate size.

  The fabric sensor 51 is provided so as to be movable in the front-rear direction by an adjustment bolt 56 that is rotatably supported by a mounting bracket 55 disposed inside the transparent cutter cover 54, and a dial 57 outside the cutter cover 54. Thus, the adjustment bolt 56 can be rotated and adjusted for movement. The mounting bracket 55 or the cutter cover 54 is provided with a scale marking 58 that can be seen through from the outside of the cutter cover 54. On the cloth sensor 51 side of the cutter cover 45, a transparent sensor cover 60 that opens and closes around the cover hinge 59 is provided. The lower surfaces of the cutter cover 54, the sensor cover 60, etc. are opened, so that the fabric is cut off and the dust on the cutter 10 is dropped.

  When changing the extrusion speed of the dough from the extrusion port 6 or the extrusion amount to large or small, the output voltage of the geared motor 20 is adjusted by operating the adjustment dial 29 and adjusting the output of the inverter 26. The rotational speed of the extrusion spiral 16 by the geared motor 20 is maintained and controlled at a set value that is adjusted.

  In order to attach the Teflon resin port ring 15 for forming the extrusion port 6 to the tube base 4, various types of the diameter of the extrusion port 6 and the like are prepared, and the tube base 4 is configured as the Teflon resin port ring 15. Regardless of the shape, the extruded dough in the tube cap 4 can be smoothly pushed and extruded, the extrusion action in the extrusion port chamber 3 can be stabilized, and it can be constructed at low cost and can be attached and detached. Can be simplified and simplified. With the configuration of the Teflon resin port ring 15, the sliding resistance of the cutter 10 to the front end edge 9 of the extrusion port 6 can be reduced and absorbed softly, and wear damage can be reduced.

  The thickness of the front end edge 9 of the extrusion port 6 is narrowed so that the sliding contact surface of the cutter 10 is narrowed so that the cut dough is quickly separated from the front end edge 9 and dropped.餅 Make sure that the dough is properly cut to prevent it from becoming a dough. Form and maintain an accurate flat shape.

  The diameter of the extrusion port 6 and the thickness of the front end edge 9 can be arbitrarily formed. Further, a cut-off interval 14 is formed over the mounting rib 8 on the outer periphery of the front end edge 9 to prevent the cut-off ridge from adhering to the front end edge 9 and the entire surface 12 of the mounting rib 8.

  The dough extruded from the extrusion cylinder 1 by the rotation of the extrusion spiral 16 receives a pressing force while being swung in the extrusion port chamber 3 in the tube cap 4 at the front end, and the extrusion port 6 at the front end of the extrusion port chamber 3. It is pushed out from. At this time, the dough is rounded and formed, or extruded in the form of a rod having the same diameter as the extrusion port 6. In this way, the dough extruded from the extrusion port 6 to the front side is cut by the cutter 10 that moves slidably along the front edge 9 of the cutting ridge ring 11 by the downward rotation of the rotating cutter 10. It is cut and separated from the subsequent extruded dough. At this time, the cut ridge ring 11 is formed of a Teflon resin material, so that the cocoon dough hardly adheres. When the kneaded dough is pushed out from the extrusion port 6, it is moved down by its own weight or the cutting resistance by the cutter 10. 9 and the front surface 12 of the mounting rib 8 is formed with a cut-off interval 14 that is cut in a right angle, so that the cut and separated scissors move closer to the mounting rib 8 surface side after passing through the action of the cutter 10. Even so, it is difficult to make contact with the mounting rib 8 surface 12, and the fall after cutting and separation can be performed accurately and smoothly. Further, even if the extruded and cut cloth may come into contact with the front surface 12 of the mounting rib 8 for some reason, the surface of the mounting rib 8 is formed of a Teflon resin material, so that the straw cloth is difficult to adhere.
