Description

Technical Field

[0001] This invention relates to the field of buckwheat noodle processing technology, specifically a device for uniformly extruding buckwheat noodles to prevent breakage. Background Technology

[0002] In the extrusion processing of buckwheat noodles and other grain products, the extrusion discharge device is one of the core equipment. Its basic working principle is: the dough material is pushed to the discharge end of the extrusion cylinder by the screw extrusion mechanism. Under pressure, the material is extruded into noodle products with specific cross-sectional shapes (such as round, flat, etc.) through the die head (forming mold) installed at the discharge end.

[0003] To enable rapid die changing for noodles of different specifications, some existing extrusion discharge devices employ a rotary disc mechanism. Multiple sets of die heads of different specifications are arranged on the rotary disc. By rotating the rotary disc, the spare die head is rotated and connected to the discharge port of the extrusion cylinder. At the same time, a cutting mechanism is used to cut the dough at the die head port, thereby eliminating the need for manual die head replacement and improving die changing efficiency.

[0004] However, when the original die head is moved away with the rotating disk, the extrusion cylinder's discharge end loses the restraint of the die head. The extrusion pressure of the dough inside the extrusion cylinder acts on the discharge end face, causing the extrusion cylinder's discharge end to undergo outward elastic bulging deformation. When the rotating disk drives the new die head to rotate and take place, this protruding fabric is very likely to come into contact with and scratch the surface of the rotating new die head, causing the fabric to be smeared and adhered to the mounting surface or working surface of the new die head. This adhesion will cause contamination of the mounting surface, affecting the subsequent sealing fit accuracy and product appearance quality. In severe cases, it may even cause the die head to fail to be installed accurately.

[0005] To address this issue, those skilled in the art have proposed a device for uniformly extruding buckwheat noodles to prevent breakage, thereby resolving the problems mentioned in the background. Summary of the Invention

[0006] The purpose of this invention is to provide a device for uniformly extruding buckwheat noodles to prevent breakage, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A buckwheat noodle uniform extrusion and discharge device for preventing breakage includes a base and an extruder body installed on the base. The two ends of the extruder body are respectively equipped with a feed hopper and a discharge cylinder. It also includes a die head, an extension component, a rotary replacement component and a magnetic suction component. The extended component includes a movable sealing cylinder and an elastic part. The movable sealing cylinder slides and seals with the inner wall of the discharge cylinder. An installation plate is installed at the end of the movable sealing cylinder away from the discharge cylinder. The installation plate is used to form an installation fit with the die head. The elastic part is disposed between the discharge cylinder and the movable sealing cylinder and is used to provide an outwardly extending elastic force for the movable sealing cylinder and to provide compensation space for the pressure of the dough inside the discharge cylinder to bulge outward. The rotating replacement assembly includes a rotating frame and a reset part. Multiple sets of mounting frames are arranged circumferentially on the rotating frame. The mold head is correspondingly assembled in the mounting frame. The rotating frame is fixedly connected to the reset part. The reset part is used to provide a reset elastic force for the rotating frame, so that the mold head after rotating into position can push the outwardly extended movable sealing cylinder to retract and reset, so that the mold head reaches the installation position. The magnetic suction component is located inside the reset part. When the rotary replacement component is powered on, the magnetic suction component generates a magnetic force. This magnetic force overcomes the elastic force applied to the rotating frame by the reset part, driving the rotating frame to move the die head axially away from the discharge cylinder. At the same time, the movable sealing cylinder extends outward under the drive of the elastic part. After moving into place, a gap is formed between the mounting plate of the movable sealing cylinder and the die head. The dough cutting and cleaning operation is completed during the rotation and repositioning of the rotating frame. When the new die head rotates to the position aligned with the movable sealing cylinder, the rotary replacement component is de-energized, the magnetic suction component loses its magnetic force, and under the action of the elastic force of the reset part, the die head pushes the mounting plate, causing the movable sealing cylinder to move together, so that the movable sealing cylinder and the die head return to the installation position.

[0008] As a preferred embodiment of the present invention, the elastic part includes multiple sets of elastic cylinders installed on the inner wall of the movable sealing cylinder. An elastic plate is slidably assembled inside the elastic cylinder. An elastic rod extending to the outside of the elastic cylinder is installed on the elastic plate. The elastic rod is slidably sealed with the end of the elastic cylinder. The end of the elastic rod away from the elastic plate is fixedly connected to the inner wall of the discharge cylinder. A first spring is provided between the end of the inner wall of the elastic cylinder and the elastic plate.

[0009] As a preferred embodiment of the present invention, the reset part includes a reset cylinder, a reset plate is slidably mounted inside the reset cylinder, a reset rod extending to the outside of the reset cylinder is mounted on the reset plate, the reset rod is fixedly connected to the rotating frame, a third spring is provided on the inner wall of the reset rod and fixedly connected to the inner wall of the reset cylinder, and a limit strip is installed on the inner wall of the reset cylinder.

[0010] As a preferred embodiment of the present invention, the magnetic attraction assembly includes a fixed magnet mounted on the reset plate, and an electromagnet is installed inside the reset cylinder at one end facing the fixed magnet.

[0011] As a preferred embodiment of the present invention, the rotating frame is provided with multiple sets of cutters arranged circumferentially, and the multiple sets of cutters are configured to correspond one-to-one with each die head.

[0012] As a preferred embodiment of the present invention, an installation block is fixedly installed at the end of the discharge cylinder, and an installation groove is provided inside the installation block, which is adapted to the outer diameter of the die head and the installation plate.

[0013] As a preferred embodiment of the present invention, the rotating replacement assembly further includes a driving part and a limiting part. The driving part is fixedly connected to the base, the driving end of the driving part is fixedly connected to the reset cylinder, and the limiting part is disposed inside the driving part.

[0014] As a preferred embodiment of the present invention, the driving unit includes a driving seat fixedly connected to the base, a driving shaft fixedly connected to the reset cylinder is rotatably mounted on the driving seat, a driving component is mounted on the driving seat, the output end of the driving component is fixedly connected to the driving shaft, and the driving component is electrically connected to the electromagnet.

[0015] As a preferred embodiment of the present invention, the limiting part includes a limiting head, and the outer wall of the drive shaft is provided with a plurality of limiting grooves that cooperate with the limiting head in the circumferential direction. The limiting head is connected to an elastic element.

[0016] As a preferred embodiment of the present invention, the elastic element includes an elastic seat fixedly connected to the drive seat, an elastic block slidably assembled inside the elastic seat, the elastic block being fixedly connected to the limiting head, and a second spring fixedly connected to the elastic block being provided at the inner wall end of the elastic seat.

[0017] The present invention has the following advantages: In this invention, when changing the mold head, the rotating replacement component is energized, allowing the magnetic suction component to drive the rotating frame through the reset part to move the mold head out of the mounting slot. Simultaneously, the movable sealing cylinder extends outward, using its internal cavity to provide volume compensation space for the compressed dough inside the discharge cylinder. During the rotating mold change process, the rotating frame drives the mold head to rotate and, in conjunction with the cutter, completes the dough cutting operation. Relying on the space compensation effect of the movable sealing cylinder, the outward deformation of the compressed dough inside the discharge cylinder is constrained within the inner cavity of the movable sealing cylinder, preventing the dough from bulging outward from the end face of the movable sealing cylinder. The new mold head can be directly rotated to the position aligned with the movable sealing cylinder. After power is cut off, under the elastic driving force of the reset part, the mold head and the movable sealing cylinder remain aligned, and the mold head pushes the movable sealing cylinder back to the installation position.

[0018] This solution effectively avoids the problem of the fabric bulging outward due to internal material pressure at the discharge cylinder port, which leads to friction and interference with the rotating die head, as well as material sticking and contamination of the die head mating surface. It also avoids sealing failure, die hole blockage, and black spot defects in the finished noodles caused by flour residue. There is no need to depressurize and shut down the extrusion system, which can achieve rapid die change without stopping the machine, improving the reliability of die change operations and production continuity of the grain extrusion equipment.

[0029] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0030] Please see Figures 1-9 A device for uniformly extruding and discharging buckwheat noodles to prevent breakage includes a base 100 and an extruder body 210 mounted on the base 100. The specific structure of the extruder body 210 is not limited, and all its components belong to the prior art, so they will not be described in detail here. The two ends of the extruder body 210 are respectively equipped with a feed hopper 220 and a discharge cylinder 230, and it also includes a die head 410, an extension component 300, a rotary replacement component 500, and a magnetic suction component 600. The extended component 300 includes a movable sealing cylinder 310 and an elastic part 330. The movable sealing cylinder 310 is slidably sealed with the inner wall of the discharge cylinder 230. An mounting plate 320 is installed at the end of the movable sealing cylinder 310 away from the discharge cylinder 230. The mounting plate 320 is used to form a mounting fit with the die head 410. The elastic part 330 is disposed between the discharge cylinder 230 and the movable sealing cylinder 310 and is used to provide an outwardly extending elastic force for the movable sealing cylinder 310 and to provide compensation space for the pressure of the dough inside the discharge cylinder 230 protruding outward. The rotating replacement assembly 500 includes a rotating frame 540 and a reset part 530. Multiple sets of mounting brackets 541 are arranged circumferentially on the rotating frame 540. The mold head 410 is correspondingly assembled in the mounting bracket 541. The rotating frame 540 is fixedly connected to the reset part 530. The reset part 530 is used to provide a reset elastic force for the rotating frame 540, so that the mold head 410 after rotating into position can push the outwardly extended movable sealing cylinder 310 to retract and reset, so that the mold head 410 reaches the installation position. The magnetic suction component 600 is disposed inside the reset part 530. When the rotary replacement component 500 is energized, the magnetic suction component 600 generates a magnetic force, which overcomes the elastic force applied by the reset part 530 to the rotating frame 540, driving the rotating frame 540 to move the die head 410 axially away from the discharge cylinder 230. At the same time, the movable sealing cylinder 310 extends outward under the drive of the elastic part 330. After moving into place, the movable sealing cylinder 310 is installed. A gap is formed between plate 320 and mold head 410. The dough cutting and cleaning operation is completed during the rotation and repositioning process of rotating frame 540. When the new mold head 410 rotates to the position aligned with the movable sealing cylinder 310, the rotating replacement component 500 is de-energized, the magnetic attraction component 600 loses its magnetic attraction, and under the elastic force of the reset part 530, the mold head 410 pushes the mounting plate 320, which drives the movable sealing cylinder 310 to move together, so that the movable sealing cylinder 310 and the mold head 410 return to the installation position together.

[0031] During the die head 410 replacement operation, the rotary replacement component 500 is energized, allowing the magnetic suction component 600 to drive the rotating frame 540 via the reset part 530 to retract the die head 410. Simultaneously, the movable sealing cylinder 310 extends outward, utilizing its internal cavity to provide volume compensation space for the compressed dough inside the discharge cylinder 230. During the rotary die replacement process, the rotating frame 540 drives the die head 410 to rotate and complete the dough cutting operation. Relying on the space compensation effect of the movable sealing cylinder 310, the outward deformation of the compressed dough inside the discharge cylinder 230 is constrained within the inner cavity of the movable sealing cylinder 310, preventing the dough from protruding outward from the end face of the movable sealing cylinder 310. The new die head 410 can directly rotate to the position aligned with the movable sealing cylinder 310. After power is cut off, under the elastic driving force of the reset part 530, the die head 410 and the movable sealing cylinder 310 remain aligned, and the die head 410 pushes the movable sealing cylinder 310 back to the installation position.

[0032] This solution effectively avoids the problem of material bulging outwards at the discharge cylinder 230 port due to internal material pressure, which causes friction and interference with the rotating die head 410, and material contamination of the die head 410 mating surface. It also avoids sealing failure, die hole blockage, and black spot defects in the finished noodles caused by dough residue. There is no need to depressurize and shut down the extrusion system, which can achieve rapid die change without stopping the machine, improving the reliability of die change operation and production continuity of the grain extrusion equipment.

[0033] Please see Figure 2 In one embodiment, an installation block 420 is fixedly installed at the end of the discharge cylinder 230. An installation groove 421 is provided inside the installation block 420. The installation groove 421 is adapted to the outer diameter of the die head 410 and the mounting plate 320. Sealing rings are provided on the inner wall of the installation groove 421, the two end faces of the mounting plate 320 and the mounting end of the die head 410.

[0034] Under normal extrusion molding conditions, under the elastic tension of the reset part 530, the die head 410 is pressed tightly against the mounting plate 320, and the movable sealing cylinder 310 is pushed back into the discharge cylinder 230. At this time, the mounting plate 320 and the die head 410 are fitted together in the mounting groove 421, with tight end face contact and high coaxiality, ensuring that the discharge end of the discharge cylinder 230 is tightly sealed, and there is no material leakage or running out during the extrusion molding process.

[0035] During the mold changing and demolding operation, the mold head 410 moves axially backward with the rotating frame 540 and disengages from the mounting groove 421, releasing the top pressure limit on the mounting plate 320. The movable sealing cylinder 310 extends outward under the action of the elastic part 330. The extended mounting plate 320 is flush with the end face of the mounting groove 421, and there is a gap between the mold head 410 that has exited the mounting groove 421 and the mounting plate 320.

[0036] After the new mold head 410 is rotated and aligned, the rotating frame 540 resets and moves forward. The new mold head 410 pushes the mounting plate 320 and the movable sealing cylinder 310 back again, so that the mounting plate 320 and the mold head 410 are accurately embedded in the mounting groove 421 again. The automatic coaxial correction and positioning fit are achieved by relying on the adaptation structure of the mounting groove 421, ensuring consistent assembly accuracy and stable sealing effect after each mold change, and effectively avoiding sealing failure and finished product quality defects caused by alignment deviation and end face clamping.

[0037] Please see Figure 5 In one embodiment, the elastic part 330 includes multiple sets of elastic cylinders 331 installed on the inner wall of the movable sealing cylinder 310. An elastic plate 332 is slidably assembled inside the elastic cylinder 331. An elastic rod 333 extending to the outside of the elastic cylinder 331 is installed on the elastic plate 332. The elastic rod 333 is slidably sealed with the end of the elastic cylinder 331, and the end of the elastic rod 333 away from the elastic plate 332 is fixedly connected to the inner wall of the discharge cylinder 230. A first spring 334 is provided between the end of the inner wall of the elastic cylinder 331 and the elastic plate 332.

[0038] When the equipment is in normal extrusion operation, the die head 410 presses against the mounting plate 320 of the movable sealing cylinder 310, forcing the movable sealing cylinder 310 to remain in a retracted state, wherein the first spring 334 is in a stretched state.

[0039] Specifically, when the mold changing operation is performed, the mold head 410 moves axially backward with the rotating frame 540. After the mold head 410 exits the mounting groove 421 and detaches from the mounting plate 320, the movable sealing cylinder 310 loses the clamping limit of the mold head 410. The stretched first spring 334 applies elastic tension to the elastic plate 332, pulling the elastic cylinder 331 to slide outward relative to the elastic rod 333, thereby driving the entire movable sealing cylinder 310 to extend smoothly outward along the inner wall of the discharge cylinder 230 until the mounting plate 320 at the end of the movable sealing cylinder 310 is flush with the end face of the mounting groove 421.

[0040] It should be noted that the inner wall of the elastic cylinder 331 is also provided with a protrusion to limit the maximum outward extension of the movable sealing cylinder 310. When the movable sealing cylinder 310 moves to its limit extension part, there will be a gap between the die head 410 and the movable sealing cylinder 310 in this state.

[0041] After the movable sealing cylinder 310 extends outward, its internal cavity forms a sufficient compensation space, which completely accommodates the outward deformation of the fabric caused by the extrusion pressure inside the discharge cylinder 230, so that the fabric will not protrude out of the cylinder opening, and completely eliminates the problem of interference and material sticking between the die head 410 and the outward protruding fabric when rotating and changing the die.

[0042] After the die change is completed and the equipment is powered off and reset, the die head 410 moves forward to press against the mounting plate 320, and pushes the movable sealing cylinder 310 back again. The elastic cylinder 331 slides in the opposite direction with the movable sealing cylinder 310, returning to the normal extrusion working state.

[0043] Please see Figure 7 In one embodiment, the reset part 530 includes a reset cylinder 531, a reset plate 532 is slidably mounted inside the reset cylinder 531, a reset rod 533 extending to the outside of the reset cylinder 531 is mounted on the reset plate 532, the reset rod 533 is fixedly connected to the rotating frame 540, a third spring 534 is provided on the inner wall of the reset rod 533 and fixedly connected to the inner wall of the reset cylinder 531, and a limit strip 535 is installed on the inner wall of the reset cylinder 531.

[0044] During normal forming operation, the third spring 534 is always in a stretched state, continuously generating an elastic pulling force on the reset rod 533 toward the inside of the reset cylinder 531, so that the rotating frame 540 always has a pressing tendency toward the discharge cylinder 230, ensuring that the die head 410 is stably pressed against the movable sealing cylinder 310.

[0045] When the mold head 410 needs to be replaced, the rotating replacement component 500 is energized, and the magnetic suction component 600 is energized simultaneously to generate a magnetic attraction force. The magnetic attraction force overcomes the tensile force of the third spring 534, pulling the reset plate 532 to slide towards the other end of the reset cylinder 531, driving the reset rod 533 to slide out of the reset cylinder 531, thereby driving the rotating frame 540 to retract, so that the mold head 410 exits the installation position and completes the axial disengagement action. At this time, the third spring 534 is further stretched, and the elastic energy storage increases.

[0046] After the mold change is completed, the magnetic suction component 600 is de-energized and demagnetized, the magnetic attraction disappears, the third spring 534 retracts and releases energy, and the elastic force of its stretching and rebound pulls the reset rod 533 back to its original position, driving the rotating frame 540 to move forward and reset, so that the new mold head 410 is precisely aligned with the mounting groove 421 and presses against the movable sealing cylinder 310, and reset together to the molding and installation position.

[0047] The limiting strip 535 provided on the inner wall of the reset cylinder 531 can mechanically limit the backward stroke of the reset plate 532, so as to avoid the third spring 534 from being overstretched, overtraveled, elastically fatigued or dislodged, and ensure that the demolding and reset strokes are consistent each time.

[0048] Please see Figure 7 In one embodiment, the magnetic attraction assembly 600 includes a fixed magnet 610 mounted on the reset plate 532, and an electromagnet 620 is mounted inside the reset cylinder 531 at one end facing the fixed magnet 610.

[0049] When the equipment is in normal forming operation, the electromagnet 620 is in a de-energized and demagnetized state, the reset part 530 is in the initial state, that is, the mold head 410 and the movable sealing cylinder 310 are in the normal working position, and the fixed magnet 610 and the electromagnet 620 are kept at a distance.

[0050] When the mold head 410 needs to be replaced, the rotating replacement assembly 500 is energized, and the electromagnet 620 is energized simultaneously to generate an attractive magnetic force. The electromagnet 620 generates an attractive pulling force toward the fixed magnet 610. This magnetic force can overcome the tensile pre-tightening elastic force of the reset part 530, thereby driving the rotating frame 540 to move backward as a whole, and the mold head 410 completes the demolding action.

[0051] Once the new mold head 410 has rotated and aligned, the electromagnet 620 is de-energized and quickly demagnetized. The attraction between the electromagnet 620 and the fixed magnet 610 completely disappears. The reset part 530 pulls the rotating frame 540 forward and resets it through elastic force, so that the new mold head 410 can accurately press against the movable sealing cylinder 310 and enter the mounting groove 421 to reset to the working position.

[0052] Please see Figure 6 In one embodiment, the rotating frame 540 is provided with multiple sets of cutters 542 arranged circumferentially, and the multiple sets of cutters 542 are configured in a one-to-one correspondence with each die head 410.

[0053] During normal production, the cutter 542 remains stationary with the rotating frame 540, does not participate in the cutting operation, and does not interfere with the normal extrusion and forming process of noodles.

[0054] During the mold changing operation, the reset unit 530 drives the mold head 410 on the rotating frame 540 to exit the mounting groove 421, and the mounting plate 320 of the movable sealing cylinder 310 moves to a position flush with the end face of the mounting groove 421. In this state, there is a gap between the mounting plate 320 and the mold head 410. As the rotating frame 540 starts to rotate, the mold head 410 generates a circumferential displacement relative to the discharge end, causing the dough between the discharge cylinder 230 and the mold head 410 to be pulled apart first. Then, the cutter 542, which rotates synchronously with the rotating frame 540, neatly cuts the dough on the end face.

[0055] Furthermore, as the die head 410 moves axially backward and away from the discharge end, the dough between the discharge cylinder 230 and the die head 410 is moderately stretched. After the dough is cut by the cutter 542, there will be residual tensile internal stress inside the dough facing the inside of the discharge cylinder 230. This residual internal stress can, to a certain extent, offset the outward bulging tendency of the dough caused by the internal extrusion of the extruder body 210. Combined with the internal volume compensation effect of the movable sealing cylinder 310, the dough on the end face can be constrained as much as possible inside the movable sealing cylinder 310, reducing the risk of the dough bulging outward.

[0056] Please see Figures 6-9In one embodiment, the rotating replacement assembly 500 further includes a driving part 510 and a limiting part 520. The driving part 510 is fixedly connected to the base 100, and the driving end of the driving part 510 is fixedly connected to the reset cylinder 531. The limiting part 520 is disposed inside the driving part 510.

[0057] Furthermore, the drive unit 510 includes a drive seat 511 fixedly connected to the base 100, a drive shaft 512 fixedly connected to the reset cylinder 531 is rotatably mounted on the drive seat 511, a drive component 513 is mounted on the drive seat 511, the output end of the drive component 513 is fixedly connected to the drive shaft 512, and the drive component 513 is electrically connected to the electromagnet 620.

[0058] When performing mold changing operations, the control system synchronously supplies power to the drive component 513 and the electromagnet 620 to achieve synchronization between the two. When the drive component 513 is energized, the magnetic attraction component 600 is energized to generate magnetic attraction force. When the drive component 513 is de-energized, the magnetic attraction component 600 is de-energized and the electromagnetic attraction force disappears.

[0059] Specifically, when the mold head 410 needs to be rotated and replaced, the drive unit 513 starts synchronously and drives the drive shaft 512 to rotate. The drive shaft 512 drives the rotating frame 540 to rotate through the reset part 530 to complete the circumferential switching of the multi-specification mold head 410, and at the same time cooperates with the cutter 542 to complete the dough cutting operation.

[0060] It should be noted that the specific structure of the drive component 513 is not limited. In this embodiment, the drive component 513 is set as a servo motor.

[0061] Furthermore, the limiting part 520 includes a limiting head 522, and the outer wall of the drive shaft 512 is provided with a plurality of limiting grooves 521 that cooperate with the limiting head 522. The limiting head 522 is connected to an elastic member 523.

[0062] The elastic element 523 includes an elastic seat 5231 fixedly connected to the drive seat 511, an elastic block 5232 slidably assembled inside the elastic seat 5231, the elastic block 5232 fixedly connected to the limiting head 522, and a second spring 5233 fixedly connected to the elastic block 5232 at the inner wall end of the elastic seat 5231.

[0063] In the initial state, the second spring 5233 is in a compressed state, which can apply an elastic thrust to the elastic block 5232 toward the drive shaft 512 side, causing the elastic block 5232 to push the limiting head 522 to always maintain sliding contact with the outer wall of the drive shaft 512, so that the limiting head 522 can smoothly slide into and out of each limiting groove 521, thereby realizing the elastic circumferential limiting of the drive shaft 512.

[0064] When the drive shaft 512 rotates, the limiting head 522 gradually slides out from the limiting groove 521. The limiting head 522 is squeezed by the outer wall of the drive shaft 512, which drives the elastic block 5232 to compress the second spring 5233, causing the limiting head 522 to retract and avoid obstructing the rotation of the drive shaft 512. When the limiting head 522 rotates to the next limiting groove 521 position, the second spring 5233 releases its elastic force to push the elastic block 5232, which in turn pushes the limiting head 522 into the limiting groove 521. During the entire rotation process, the limiting head 522 can slide along the outer surface of the drive shaft 512 to achieve groove-by-groove transition.

[0065] After the drive component 513 stops working due to power failure, the circumferential position of the drive shaft 512 can be effectively locked by the snap-fit ​​between the limit head 522 and the limit groove 521, so that the rotating frame 540 remains in a fixed position. This ensures that the mold head 410 and the movable sealing cylinder 310 are accurately aligned after the mold change is completed, providing a stable positioning basis for the subsequent accurate push of the mold head 410 back into position and sealing fit by the reset part 530.

[0066] The working principle of this invention is as follows: During normal extrusion molding production, the reset part 530 is in the initial state, which causes the rotating frame 540 to drive the die head 410 to always press and fit tightly in the mounting groove 421 at the end of the discharge cylinder 230, ensuring that the die head 410 and the movable sealing cylinder 310 are sealed and aligned, and the material is discharged stably; the elastic part 330 is in the initial state, which keeps the movable sealing cylinder 310 in a retracted and fitted state, without affecting the normal extrusion discharge.

[0067] When the die head 410 needs to be quickly replaced, the equipment control system energizes the drive component 513, and the magnetic suction component 600 is simultaneously energized to generate a magnetic force. The magnetic force can overcome the tensile preload of the reset part 530, drive the reset part 530, thereby causing the rotating frame 540 to move backward as a whole. The die head 410 exits the mounting groove 421 and forms a gap with the mounting plate 320. After the die head 410 moves backward and releases the limit, the elastic force of the elastic part 330 will drive the movable sealing cylinder 310 to extend outward until the mounting plate 320 is flush with the end face of the mounting groove 421. The internal space of the movable sealing cylinder 310 forms a volume compensation, which constrains the bulging deformation of the dough in the discharge cylinder 230 within the cylinder, preventing the dough from bulging outward.

[0068] At the same time, the drive component 513 drives the drive shaft 512 to rotate, and the rotating frame 540 rotates synchronously with the drive shaft 512. During the rotation, the dough between the mold head 410 and the discharge cylinder 230 is misaligned and torn off, and the cutter 542, which is configured to correspond one-to-one with the mold head 410, rotates synchronously to neatly cut the dough that has been torn off between the discharge cylinder 230 and the mold head 410.

[0069] After the mold change and alignment are completed, the drive component 513 is de-energized, the magnetic suction component 600 is simultaneously de-energized and demagnetized, and the drive stops. The magnetic suction constraint force disappears, and the reset part 530 drives the rotating frame 540 to move forward as a whole, so that the new mold head 410 is precisely aligned with the movable sealing cylinder 310 and presses it back to reset. Finally, the mold head 410 and the mounting plate 320 are fitted into the mounting groove 421 again, restoring the sealing and molding position.
