Description

Technical Field

[0001] This utility model relates to the field of food processing machines, specifically a noodle machine. Background Technology

[0002] A pasta machine is a tool that mixes flour and water and extrudes it to make pasta. For example, Chinese patent document CN222639562U discloses a noodle machine, including a dough-containing barrel with a dough-containing cavity and an extrusion tube. An extrusion cylinder is coaxially installed inside the extrusion tube. A stirring and extrusion assembly is rotatably connected inside the dough-containing barrel. The stirring and extrusion assembly includes a kneading rod and an extrusion rod that are connected to each other through transmission. The kneading rod is rotatably disposed in the dough-containing cavity, and the extrusion rod is rotatably disposed in the extrusion cylinder. A conical guide cavity is provided between the dough-containing cavity and the extrusion tube. The diameter of the conical guide cavity gradually decreases from the dough-containing cavity to the extrusion tube. The tail end of the extrusion cylinder is provided with a feed plate with a vertical cross section of U-shape or J-shape. The feed plate extends from the tail end of the extrusion tube toward the dough-containing cavity and into the conical guide cavity. The conical guide cavity is provided with a guide rod extending from its inner bottom toward the dough-containing cavity. The end and top of the feed plate are open. The guide rod is inclined from top to bottom and abuts against the top of the feed plate. The two together constitute the extrusion feed port.

[0003] This type of noodle machine has a pressure plate for pressing down the dough container. In the prior art, a micro switch is usually installed between the pressure plate and the main unit. The micro switch plays a protective role. After the pressure plate is correctly installed on the main unit, it can press down the micro switch, and the control components of the noodle machine can control the start of the drive motor.

[0004] Currently, in this type of noodle machine, the microswitch can only be used to detect whether the pressure plate and the main unit are correctly installed (only after both are correctly installed can the control component control the start of the drive motor for protection). It cannot detect whether the noodle extrusion nut is correctly installed with the pressure plate (if the noodle extrusion nut is not correctly installed with the pressure plate, the mixing and extrusion components of the noodle machine will still be exposed, and if the drive motor of the noodle machine starts unexpectedly, there is still a risk of injuring the operator's hand). There is still a significant safety hazard. The protection mechanism achieved by the microswitch has blind spots and needs further improvement. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a noodle machine in which the micro switch trigger can be engaged only after the pressure plate and the noodle outlet nut are correctly installed at the same time.

[0006] The purpose of this utility model is achieved as follows:

[0007] A noodle machine includes a dough container with a dough outlet tube, a main unit with an installation port, a pressure plate with a pressure plate nut, and a dough outlet nut. The dough container is detachably installed on the installation port. The main unit has pressure plate studs on opposite sides of the installation port. The pressure plate presses against the main unit and the periphery of the dough outlet tube. The pressure plate nut and the pressure plate studs are tightened together, so that the pressure plate presses tightly against the main unit and simultaneously presses the dough container tightly against the installation port. The dough outlet nut is tightened on the dough outlet tube and presses against the pressure plate. A micro switch is provided inside the main unit. The trigger of the micro switch extends out of the main unit and faces the pressing position of the pressure plate. A pressure rod is provided inside the pressure plate. The first end of the pressure rod extends out of the pressure plate and faces the trigger, and the last end extends out of the pressure plate and faces the dough outlet nut, pressing against the pressure plate. When the dough outlet nut is tightened on the dough outlet tube and presses against the pressure plate, the dough outlet nut presses against the last end of the pressure rod, causing the pressure rod to move towards the trigger, and then causing the first end of the pressure rod to press against the trigger of the micro switch.

[0008] The trigger includes a switch foot with elastic reset and a connecting rod disposed on the micro switch. The micro switch is fixedly installed inside the main unit, and the connecting rod is movably installed on the main unit. One end of the connecting rod abuts against the switch foot, and the other end extends out of the main unit.

[0009] The main unit is equipped with a mounting bracket, and the micro switch is mounted on the mounting bracket.

[0010] The pressure plate is provided with a pressure plate bracket, and the pressure plate bracket extends along the movement direction of the pressure rod with a support column. The support column passes through the pressure rod and limits the movement of the pressure rod between the pressure plate bracket and the pressure plate.

[0011] The support column is equipped with a spring for keeping the tail end of the pressure rod extended out of the pressure plate when the pressure rod is reset. One end of the spring abuts against the pressure rod, and the other end abuts against the pressure plate bracket.

[0012] The mixing and extrusion assembly is detachably installed inside the container, and the extrusion die head is detachably installed on the extrusion tube. When the extrusion nut is tightened on the extrusion tube, the extrusion nut fixes the extrusion die head on the extrusion tube.

[0013] The host is equipped with a control component and a drive motor. The micro switch and the drive motor are electrically connected to the control component. The control component can only control the start of the drive motor after the trigger of the micro switch is pressed.

[0014] The beneficial effects of this utility model are as follows:

[0015] By setting pressure rods on the pressure plate that are linked to the noodle-dispensing nut and the trigger of the micro switch respectively, the noodle machine can only work normally after the pressure plate and the noodle-dispensing nut are correctly installed. The noodle-dispensing nut presses down on the pressure rod, and the pressure rod then presses down on the trigger of the micro switch.

[0016] That is, the trigger of the micro switch can only be engaged after the pressure plate and the outlet nut are correctly installed. The micro switch can simultaneously detect whether the pressure plate and the outlet nut are correctly installed, thus providing better protection and reducing the blind spots of the protection mechanism achieved by the micro switch.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First Embodiment

[0026] See Figures 1-7This noodle machine includes a dough container 1 with a dough outlet tube 11, a main unit 2 with an installation port 20, a pressure plate 3 with a pressure plate nut 30, and a dough outlet nut 4. The dough container 1 is detachably installed on the installation port 20. The main unit 2 has pressure plate studs 22 on opposite sides of the installation port 20. The pressure plate 3 presses against the main unit 2 and the periphery of the dough outlet tube 11. The pressure plate nut 30 and the pressure plate studs 22 are tightened together, so that the pressure plate 3 presses tightly against the main unit 2 and simultaneously presses the dough container 1 tightly against the installation port 20. The dough outlet nut 4 is tightened onto the dough outlet tube 11 and presses against the pressure plate 3 or... The microswitch 5 is installed inside the main unit 2 and rests against the pressure plate 3. The trigger of the microswitch 5 extends partially out of the main unit 2 and presses against the pressure plate 3. A pressure rod 31 is installed inside the pressure plate 3. The first end of the pressure rod 31 extends partially out of the pressure plate 3 and faces the trigger, while the last end extends partially out of the pressure plate 3 and presses against the pressure plate 3 towards the outlet nut 4. When the outlet nut 4 is tightened onto the outlet tube 11 and presses against or rests against the pressure plate 3, the outlet nut 4 presses against the last end of the pressure rod 31, causing the pressure rod 31 to move towards the trigger, thereby causing the first end of the pressure rod 31 to press against the trigger of the microswitch 5. Figure 5 and Figure 6 As shown, the trigger of the micro switch 5 can only be engaged after the pressure plate 3 and the noodle outlet nut 4 are correctly installed. The micro switch 5 can simultaneously detect whether the pressure plate 3 and the noodle outlet nut 4 are correctly installed, thus providing better protection and reducing the blind spots of the protection mechanism achieved by the micro switch (after the pressure plate 3 and the noodle outlet nut 4 are correctly installed, the mixing and extruding components will not be exposed, thus preventing the drive motor 25 from accidentally starting and injuring people's hands).

[0027] Furthermore, the trigger includes a switch foot 51 with elastic reset and a connecting rod 52 disposed on the micro switch 5. The micro switch 5 is fixedly installed inside the host 1, and the connecting rod 52 is movably installed on the host 1. One end of the connecting rod 52 abuts against the switch foot 51, and the other end extends out of the host 1, as will be understood by those skilled in the art.

[0028] Furthermore, the host 2 is provided with a mounting bracket 23, and the micro switch 4 is mounted on the mounting bracket 23, as will be understood by those skilled in the art.

[0029] Furthermore, the pressure plate 3 is provided with a pressure plate bracket 33 fixedly installed. The pressure plate bracket 33 extends along the movement direction of the pressure rod 31 and is provided with a support column 331. The support column 331 passes through the pressure rod 31 and limits the movement of the pressure rod 31 between the pressure plate bracket 33 and the pressure plate 3. They are easy to assemble and have a simple structure.

[0030] Furthermore, the support column 331 is provided with a spring 34 for keeping the tail end of the pressure rod 31 extended out of the pressure plate 3 when it is reset. One end of the spring 34 abuts against the pressure rod 31, and the other end abuts against the pressure plate bracket 33. The spring allows the pressure rod 31 to be reset. When reset, its tail end is kept extended out of the pressure plate 3, that is, the pressure rod 31 is not pressed by the nut 4 and cannot actively press the trigger of the micro switch 5, which is safer.

[0031] Furthermore, a mixing and extruding assembly (not shown in the figure, but understood by those skilled in the art) is detachably installed inside the dough container 1, and a dough extrusion die head 12 is detachably installed on the dough extrusion tube 11. When the dough extrusion nut 4 is tightened on the dough extrusion tube 11, the dough extrusion nut 4 fixes the dough extrusion die head 12 on the dough extrusion tube 11.

[0032] Furthermore, the host 2 is equipped with a control component 24 and a drive motor 25. The micro switch 5 and the drive motor 25 are electrically connected to the control component 24. The control component 24 can only control the start of the drive motor 25 after the trigger of the micro switch 5 is pressed. The simplified circuit diagram is shown below. Figure 7 As shown, the principle of this circuit can be understood by those skilled in the art. After the structural improvement of this solution, the trigger of the micro switch 5 is changed from being driven by the original pressure plate 3 to being driven by the protruding nut 4, thereby reducing the blind spot of the protection mechanism achieved by the micro switch.

[0033] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
