Description

Technical Field

[0001] The utility model relates to the technical field of household food processing equipment, in particular to a handheld noodle pressing machine. Background Art

[0002] The use of household noodle making machines that can directly process dough into noodles is very popular among families because of its convenience. You only need to put the dough into the noodle extrusion cylinder, and then squeeze the dough out of the hole to form noodles through the piston extrusion principle. The end of the noodle extrusion cylinder of the existing noodle making machine that cooperates with the main machine is provided with an L-shaped card slot body, and the main machine is correspondingly provided with a protrusion. After the protrusion is inserted into the slot body, it rotates a certain angle along the path of the slot body to realize the assembly connection between the noodle extrusion cylinder and the main machine. However, although the existing assembly connection method achieves the connection purpose, it has a complex structure, which not only increases the manufacturing cost, but also increases the overall weight of the noodle press, which is contrary to the handheld concept.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0017] The utility model includes a noodle pressing machine body 1, which includes a shell with an installation cavity therein, the shell including a hand-held portion 12 and a main unit 13, a push rod 2 is arranged in the main unit 13, the hand-held portion 12 is located at the rear end of the shell, a noodle extruding cylinder 11 is arranged at the front end of the shell, the noodle extruding cylinder 11 is detachably connected to the front end of the shell, the noodle extruding cylinder 11 is communicated with the inner cavity of the main unit 13 of the shell, a driving component is also arranged in the noodle pressing machine body 1, that is, a driving component is arranged in the main unit 13, the push rod 2 is a retractable rod-shaped member, the rear end of the push rod 2 is connected to the driving component, the front end extends into the noodle extruding cylinder 11 and a noodle pressing end is arranged on the top of the front end, and the push rod 2 performs a reciprocating telescopic action back and forth under the drive of the driving component to realize the noodle pressing work.

[0018] The driving assembly includes a motor 3 and a screw pair. The motor 3 is installed in the main machine part 13. The motor 3 is connected to the screw 4 in the screw pair and drives the screw 4 to rotate. The screw 4 is arranged horizontally. The rear end of the screw 4 is connected to the output shaft of the motor 3. The front end of the screw 4 is rotatably connected to the main machine part 13 through a bearing. The nut 5 in the screw pair is connected to the push rod 2 to drive the push rod 2 to extend and retract back and forth between the noodle extrusion cylinder 11 and the noodle press body 1. A slider 6 is installed at the rear end of the push rod 2. The slider 6 is fixed on the nut 5 or integrated with the nut 5. The slider 6 moves back and forth with the extension and retraction of the push rod 2. Limit switches 8 are respectively provided at the two extreme positions of the extension and retraction of the slider 6 inside the noodle press body 1. One limit switch 8 is located at the front end of the main machine part 13, that is, the push rod 2 squeezes flour to form noodles. The limit position, another limit switch 8 is located at the rear end of the main machine part 13, that is, the push rod 2 returns to the innermost position after pressing, and the slider 6 is correspondingly provided with a trigger part 7 that senses the limit switch 8. The slider 6 moves with the extension and retraction of the push rod 2. When the slider 6 is extended and retracted to the front end with the push rod 2, that is, when the noodles are completely pressed out, the trigger part 7 on the slider 6 is induced by the limit switch 8 at this position, and the signal is fed back to the control center. The control center controls the push rod 2 to stop the action to prevent the push rod 2 from continuing to extend forward and avoid damage by hard collision with the pressing end; when the slider 6 is extended and retracted to the rearmost end with the push rod 2, that is, the push rod 2 returns after pressing the noodles, the trigger part 7 on the slider 6 is induced by another limit switch 8, so that the push rod 2 stops.

[0019] It should be noted that when the slider 6 is extended and retracted to the front end along with the push rod 2, that is, when the surface is fully pressed, the push rod 2 stops extending and retracting under the induction of the slider 6 and the limit switch 8. Of course, it can also retreat automatically, that is, the push rod 2 retreats to the rear end.

[0020] A control center electrically connected to the driving assembly, the limit switch 8 and the trigger part 7 is also provided in the noodle making machine body 1. The control center is a control panel, in which the power source can be an external power source or a charger. The charger is located in the handheld part 12. The specific structure and working principle are not described here.

[0021] Both ends of the screw rod 4 are fixed in the noodle press body 1 through bearings, that is, one end of the screw rod 4 is connected to the output shaft of the motor 3 through a bearing, and the other end is connected to the main machine part 13 through a bearing, so that the screw rod 4 can stably rotate forward and reverse under the drive of the motor 3.

[0022] The inner wall of the main body part 13 is provided with a guide groove 9 along the moving direction of the slider 6. The guide groove 9 is arranged in the same direction as the screw rod 4. The slider 6 is provided with a protrusion 10 that forms a guiding match with the guide groove 9. The protrusion 10 is slidably connected in the guide groove 9. When the slider 6 moves back and forth, the protrusion 10 is driven to move back and forth along the guide groove 9. The sliding match between the protrusion 10 and the guide groove 9 makes the movement of the slider 6 more stable.

[0023] The inner wall of the main body 13 is provided with guide grooves 9 on both sides of the slider 6 . The two guide grooves 9 are symmetrically arranged, and the slider 6 is correspondingly provided with protrusions 10 , so that the slider 6 can stably slide forward and backward along the guide grooves 9 .

[0024] The inner wall of the main body part 13 is provided with criss-cross grid-like reinforcement ribs 14. In this embodiment, the grid is a square grid, so that the limit switch 8 can be embedded in the grid-like reinforcement ribs 14, and the installation is more firm and stable, so that the noodle press will not fall off when it is shaken violently.

[0025] The grid-like reinforcing rib 14 is provided with a groove body as a guide groove 9 along the moving direction of the slider 6, that is, the guide groove 9 is located on the grid-like reinforcing rib 14. The grid-like reinforcing rib 14 also has two, which are respectively arranged on both sides of the axial direction of the screw pair. The grid-like reinforcing ribs 14 on both sides are provided with symmetrical guide grooves 9, and the protrusions 10 are also symmetrically arranged on both sides of the slider 6. This not only makes the internal structure of the main unit 13 more compact, but also improves space utilization.

[0026] The limit switch in this embodiment is a conventional contact limit switch, and the specific model and working principle are not described here.

[0027] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
