[0002] At present, when preparing quick-frozen noodles, extrusion molding equipment is often needed to extrude the kneaded noodles into the shape of noodles. There are many existing extrusion molding devices for preparing noodles. Among them, in the existing public documents, CN218184976U discloses a noodle extrusion molding device, which is publicly provided with a base, a support frame is fixedly connected to the base, a horizontal frame is fixedly connected to the support frame, a molding bin is clamped on the horizontal frame, the molding bin includes an upper bin and a lower bin, the upper bin and the lower bin are clamped with each other, and a molding hole is opened on the inclined surface, and a lifting shaft is also fixedly connected to the base, a top plate is fixedly connected to the lifting shaft, and a pressing plate is arranged below the top plate.

[0003] Although the above-mentioned extrusion molding device can be used for noodle extrusion molding, if different noodles need to be extruded, different discharging molds need to be manually replaced, which is cumbersome to operate, and manual replacement is time-consuming and labor-intensive, reducing production efficiency. In addition, the existing extrusion molding device has low functionality and can often only be used for noodle extrusion. After the noodles are extruded, they need to be transported to the next process through an external feeding device.

The hand rods 403 on both sides of a set of axle rods 401 are respectively connected by the connecting pieces 404 on both sides.

[0094] Specifically, each of the hand bars 403 on both sides of the material drying assembly 480A is placed in the connecting grooves 471 of the corresponding shaft seats 470 on both sides.

[0095] Furthermore, the connecting member 404 includes a connecting plate 4041 and a sleeve 4042. A group of evenly distributed sleeves 4042 are fixed to the inner side of the connecting plate 4041. The size of the sleeve 4042 matches the size of the horizontal handle at the top of the hand bar 403. The horizontal handle of the hand bar 403 is plugged into the corresponding sleeve 4042.

[0096] The operation process of this embodiment is as follows: when using the drying assembly 480A to temporarily store noodles, first, in the same manner as described above, the movable seat 430 is moved outward as a whole for use, and then a set of shafts 401 are connected by two connecting pieces 404, and the corresponding hand rods 403 and sleeves 4042 are plugged in, and the assembly of the drying assembly 480A is completed. After the two drying assemblies 480A are assembled in sequence, the two drying assemblies 480A are respectively placed between the two rows of shaft seats 470 of the material placing mechanism 400, and the hand rods 403 of the drying assembly 480A are placed in the connecting grooves 471 of the corresponding shaft seats 470, and the installation operation of the two drying assemblies 480A is completed;

[0097] During processing, the noodles taken out after cutting are hung on the shafts 401 of the inner drying assembly 480A respectively. When the shafts 401 of the inner drying assembly 480A are full of noodles, the drying assembly 480A is immediately taken out, and an empty drying assembly 480A is replaced for temporary storage of noodles again. Then, the operator can send the taken out drying assembly 480A full of noodles to boil as a whole, and then the temporary storage and unloading are circulated in the same way as above.

[0098] After boiling, the operator puts the drying component 480A containing the boiled noodles back into the loading mechanism 400, and then starts the blowing components 460 in the inner lifting side seat 440 facing the outer drying component 480A through the control switch, while the blowing components 460 in the inner lifting side seat 440 facing the inner drying component 480A are not used. When some of the outer blowing components 460 are started, the blowing components 460 are set to blow out cold air or hot air according to the use needs. When drying the noodles after boiling, the surface of the noodles hanging on the boiled drying component 480A can be quickly drained of water through the blowing effect of some of the outer blowing components 460 of the inner lifting side seat 440.

[0099] In addition, when the noodles to be hung are long, the hydraulic cylinders 4001 in the inner lifting side seats 440 on both sides can synchronously drive the inner lifting side seats 440 on both sides to move upward synchronously, thereby raising the height of the drying assembly 480A for use;

[0100] If it is necessary to dry the long noodles after adjusting the height, the blowing components 460 of the inner lifting side seats 440 facing the outer drying components 480A and the blowing components 460 of the outer lifting side seats 450 facing the outer drying components 480A are started simultaneously. When some of the outer blowing components 460 are started, the blowing components 460 are set to blow out cold air or hot air according to the needs. When drying the noodles after boiling, the blowing effect of some of the outer blowing components 460 of the inner lifting side seats 440 and the blowing effect of some of the outer blowing components 460 of the outer lifting side seats 450 can quickly drain the water from the surface of the long noodles hanging on the drying components 480A after boiling after adjusting the height.

The hand rods 403 on both sides of the toothed stick 402 are detachably connected to the corresponding shaft seats 470 on both sides through the locking rod 406.

[0102] Specifically, a limiting hole 4031 is provided on the hand lever 403 , and the diameter of the limiting hole 4031 is smaller than the diameter of the screw hole 472 , and the diameter of the limiting hole 4031 is the same as the diameter of the insertion hole 473 .

[0103] Furthermore, the inner side of the locking rod 406 is a threaded portion, the size of which matches the size of the screw hole 472 , and the outer side of the locking rod 406 is a rod portion, the size of which matches the size of the limiting hole 4031 and the size of the socket 473 .

[0104] The operation process of this embodiment is as follows: when the feeding assembly 480B is used to transport noodles, the movable seat 430 is first moved outward as a whole in the same manner as described above. When the movable seat 430 is moved outward as a whole, the driving gear is driven to rotate by the action of the fifth motor 442, and the second gear ring 444 is immediately driven to rotate by the transmission action of the toothed belt 443, thereby driving the belt body 405 to rotate;

[0105] Then, each hand rod 403 of the feeding assembly 480B is placed in the connecting groove 471 of the corresponding shaft seat 470 on both sides, and then the locking rod 406 is screwed into the corresponding overlapping limiting hole 4031, screw hole 472 and plug hole 473, and each hand rod 403 and shaft seat 470 are locked, and the feeding assembly 480B can be completed;

[0106] During processing, the noodles taken out after cutting are placed on the belt body 405, and the noodles can be transported to the next process;

[0107] In addition, when the feeding assembly 480B is used to transport the noodles, if the noodles need to be dried, first, the hydraulic cylinders 4001 in the outer lifting side seats 450 on both sides are used to synchronously drive the outer lifting side seats 450 on both sides to move upward synchronously, and then the blowing assemblies 460 in each outer lifting side seat 450 are synchronously started. When the blowing assemblies 460 are started, the blowing assemblies 460 are set to blow out cold air or hot air according to the needs of use. When the noodles are transported, the noodles transported on the belt body 405 can be dried by the blowing effect of the blowing assemblies 460 after they are moved upward. Example 5
