Description

Technical Field

[0001] The present invention relates to the technical field of machinery or equipment for making or processing dough food, and particularly relates to a punching and cutting machine for preventing pastries from sticking. Background Art

[0002] In the process of pastry preparation, pastries need to go through many processing steps. Before baking some pastries, in order to make the pastries evenly heated and facilitate subsequent packaging, it is necessary to punch and cut the pastries before baking.

[0003] In the prior art, when punching and cutting pastries, a mold is required. With the development of technology, the molds for cutting and punching are integrated together. Specifically, structures for cutting and punching are respectively arranged on a cylindrical mold, and the mold rotates along with the conveyance of the pastries on the production line. When the mold rotates, the cutting structure and the punching structure at the bottom come into contact with the pastries to achieve the punching and cutting actions of the pastries. However, as the usage time of the mold increases, the mold will inevitably be worn or the pastries will stick, which will affect the punching and cutting effect of the mold. Therefore, it is necessary to repair or clean the mold. However, during the disassembly and assembly of the mold, the pastries cannot be processed by the mold, and thus the subsequent processing actions cannot continue. Only the production line can be temporarily stopped until the replaced mold is installed and then the operation can continue, resulting in a reduction in the overall processing efficiency. Moreover, the overall size of the mold is relatively large, and it takes a lot of time and energy for personnel to disassemble and assemble, leading to a further reduction in efficiency.

[0004] Therefore, a punching and cutting machine for preventing pastries from sticking is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a punching and cutting machine for preventing pastries from sticking to solve the problem that the production line cannot continue to operate and the disassembly and assembly efficiency is low when the mold is disassembled, replaced, and assembled.

[0006] The present invention specifically adopts the following technical solutions to achieve the above purpose:

[0007] A punching and slitting machine for preventing pastries from sticking together, comprising a water line conveyor belt and a die plate arranged on the assembly line conveyor belt. The number of the die plates is six. The die plates are trapezoidal prisms and one side surface is curved. A splicing component for splicing the die plates is arranged on the assembly line conveyor belt. The six die plates are spliced into a cylindrical shape through the splicing component, and the inner side wall of the die plate is flat. Slitting teeth and punching columns are arranged on both the outer side wall and the inner side wall of the die plate. A motor for driving the die plate to rotate is arranged on the splicing component. A separating component for detaching a single die plate from the splicing component by stretching is arranged on the assembly line conveyor belt. A displacement component for driving the splicing component and the separating component to rotate and move is arranged on the assembly line conveyor belt. A cleaning component for cleaning the die plate is also arranged on the assembly line conveyor belt.

[0008] Further, the splicing component includes an insertion plate, a sleeve column, a magnet and a connection disk. One side surface of the die plate is connected to the insertion plate. The cross-section of the insertion plate is in an inverted L shape. A plurality of insertion holes are formed in the outer wall of the sleeve column and are inserted with the insertion plate. Magnets are arranged on both the insertion plate and inside the sleeve column. The sleeve column adsorbs the insertion plate through the magnetic force of the magnet. The side surface of the sleeve column is open and is connected to the connection disk. The connection disk is provided with six sensors for detecting the position of the insertion plate. The side surface of the connection disk is perforated. The transmission shaft of the motor passes through the connection disk and is connected to the sleeve column. The transmission shaft of the motor is rotatably connected to the connection disk.

[0009] Further, the separating component includes a telescopic frame, a telescopic device and a extraction plate. The telescopic frame is in a frame shape. The top of the telescopic frame is connected to the telescopic device. The extraction plate is arranged at the transmission end of the telescopic device. The extraction plate is in an L shape. An extraction groove is formed in the inner wall surface of the die plate corresponding to the position of the extraction plate.

[0010] Further, the separating component further includes a fixing plate, a threaded column, a toothed column and a toothed plate. The fixing plate is connected to the extraction plate. The fixing plate is threadedly connected to the threaded column. The outer end of the threaded column is connected to the toothed column. The inner wall of the telescopic frame is connected to the toothed plate. The toothed column and the toothed plate are in corresponding positions. A positioning groove corresponding to the threaded column is formed in the side wall of the die plate.

[0011] Further, the displacement component includes a transverse movement device, a rotating device, a semi-cylindrical bevel gear, a bevel gear, a rotating shaft, and a driving plate. The transverse movement device is installed at the bottom of the assembly line conveyor belt. The rotating device is installed at the moving end of the transverse movement device. The transmission shaft of the rotating device is connected to the semi-cylindrical bevel gear. The moving end of the transverse movement device is tightly sleeved with two rotating shafts through a rotating frame. The two rotating shafts are distributed left and right relative to the semi-cylindrical bevel gear. The corresponding ends of the two rotating shafts are connected to the bevel gears. The two bevel gears are both meshed with one side of the semi-cylindrical bevel gear. The left rotating shaft is connected to the telescopic frame. The right rotating shaft is connected to the driving plate. The driving plate is connected to the sleeve column.

[0012] Further, the cleaning component includes a connecting frame, a cleaning disk, and a cleaning column. One side of the assembly line conveyor belt is connected to the connecting frame. The top of the connecting frame is connected to the cleaning disk. The connecting frame and the driving plate are arranged in a cross shape to avoid movement interference. The cleaning column is connected to the cleaning disk. Brushes are provided on the outer wall of the cleaning column and the lower part of the cleaning disk.

[0013] Further, the cleaning component further includes a dust suction groove, a plug cylinder, a one-way valve, a sleeve, a plug plate, and a through pipe. Dust suction grooves are opened on the left and right sides of the lower part of the cleaning disk. An opening is provided on the top surface of the dust suction groove. The bottom of the telescopic frame is connected to the plug cylinder. The inner wall of the plug cylinder is sleeved with the plug plate. The bottom surface of the extraction plate is connected to the sleeve. The bottom end of the sleeve is connected to the plug plate. The bottom of the plug cylinder is connected to two one-way valves. The two one-way valves can respectively input into the plug cylinder and output from the plug cylinder. The one-way valve that can input into the plug cylinder is connected and communicated with the dust suction groove through the through pipe. A sieve mesh is provided at the connection port of the through pipe and the dust suction groove.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. When a mold plate at a certain position is broken or has other problems and needs to be repaired or replaced, after the mold plate stops, the separation component detaches one mold plate at the corresponding position from the splicing component. At this time, the pastry with interrupted cutting on the assembly line conveyor belt moves to the front side of the mold plate. The displacement component rotates the separation component and drives the mold plate to move forward to this position. The separation component reciprocates up and down, enabling the cutting teeth and punching columns on the plane of the mold plate to perform punching and cutting on the interrupted part and subsequent parts of the pastry, ensuring that the processing of the pastry will not be interrupted. Then, personnel can disassemble and assemble the subsequent mold plates on the splicing component to achieve the disassembly and repair of the mold plate, thereby achieving the effect of disassembling and repairing the mold plate without stopping the machine.

[0016] 2. Through the splicing setting of the die plates in the present invention, only the die plate at the single faulty position needs to be replaced each time. Its size and other factors are smaller than those of the overall die, so it is convenient for personnel to disassemble and assemble, having the advantages of labor saving and low maintenance difficulty.

[0017] 3. After the disassembly, assembly and maintenance of the die plates in the present invention are completed, the die plates on the separation component are reconnected to the splicing component by rotating backward, and continue to move forward to the interruption position of the pastry punching and cutting during the rotation process. Then, the rotation of the die plates is started to continue punching and cutting the pastry, and the rotation frequency of the die plates controlled by the motor is increased, so as to move backward and reset while rotating. After resetting to the initial position, the motor is controlled to reduce the frequency to the initial state, completing the installation of the die plates in the state of non-stop operation.

[0018] 4. Through the connection of the threaded posts and the positioning grooves in the present invention, in cooperation with the toothed plates, the complete limitation of the die plates is realized, avoiding the displacement of the die plates at various angles, and thus ensuring stability during the subsequent cutting and punching actions and improving the quality of the products.

[0019] 5. During the process of the driving plate rotating to the vertical state in the present invention, the die plates are rotated to make the notch correspond to the cleaning posts. Then, after the driving plate rotates to the vertical state, the die plates can be inserted into the cleaning posts, making the inner side walls of the die plates correspond to the cleaning posts and the outer side walls of the die plates correspond to the brushes on the cleaning disc. Then, the motor is started to drive the die plates to rotate. Through the connection of the inner side walls and the outer side walls of the die plates with the brushes when the die plates rotate, the pastries adhered to the die plates are cleaned off, thus realizing the automatic cleaning of the die plates, improving the convenience and efficiency of cleaning, and also avoiding the reduction of the punching and cutting effect caused by the adhesion and condensation of pastries on the die plates after long-term operation, and further ensuring the overall quality of the products.

[0020] 6. When the extraction plate drives the die plates to reciprocate up and down for punching and cutting actions in the present invention, the plug plate slides in the plug cylinder along with the action of the extraction plate through the sleeve and generates negative pressure. The negative pressure effect is transmitted to the dust suction groove through the one-way valve and the connecting pipe. The top of the dust suction groove sucks the pastries generated and dropped during the cleaning of the die plates through negative pressure, avoiding the pastries from falling back onto the assembly line conveyor belt, thus avoiding the damage to the quality of the products on the assembly line conveyor belt, and further cleaning the brushes on the cleaning disc and the cleaning posts through the suction force, improving the service life of the brushes, and further improving the convenience of cleaning.

[0033] As Figure 1 shown, a punching and slitting machine for preventing pastries from sticking includes a water line conveyor belt 1 and a die plate 2 provided on the assembly line conveyor belt 1. The number of die plates 2 is six. The die plate 2 is in the shape of a frustum of a pyramid and one side surface is curved. A splicing component 3 for splicing the die plates 2 is provided on the assembly line conveyor belt 1. The six die plates 2 are spliced into a cylindrical shape through the splicing component 3, and the inner side wall of the die plate 2 is flat. Cutting teeth and punching columns are provided on both the outer side wall and the inner side wall of the die plate 2. A motor for driving the die plate 2 to rotate is provided on the splicing component 3. A separating component 4 for detaching a single die plate 2 from the splicing component 3 by stretching is provided on the assembly line conveyor belt 1. A displacement component 5 for driving the splicing component 3 and the separating component 4 to rotate and move is provided on the assembly line conveyor belt 1. A cleaning component 6 for cleaning the die plate 2 is also provided on the assembly line conveyor belt 1.

[0034] Specifically, when the pastries are conveyed on the assembly line, the motor drives the mold plate 2 to rotate, enabling the cutting teeth and punching posts on the bottom wall of the mold plate 2 to contact the pastries, thereby achieving cutting and punching of the pastries. When there are problems such as breakage of the mold plate 2 at a certain position and it needs to be repaired and replaced, after the mold plate 2 stops, the separation component 4 detaches one mold plate 2 at the corresponding position from the splicing component 3. At this time, the pastries with interrupted cutting on the assembly line conveyor belt 1 move to the front side of the mold plate 2. The displacement component 5 rotates the separation component 4 and drives the mold plate 2 to move forward to this position. The separation component 4 reciprocates up and down, enabling the cutting teeth and punching posts on the plane of the mold plate 2 to perform cutting and punching on the interrupted part and subsequent parts of the pastries, ensuring that the processing of the pastries will not be interrupted. It should be noted that when the separation component 4 descends, it can move a certain distance along with the pastries through the displacement component 5 and then reset when the separation component 4 ascends to ensure the cutting and punching effect and avoid squeezing the pastries on the side and causing deformation. Then, personnel can disassemble and assemble the subsequent mold plates 2 on the splicing component 3 to achieve the repair and replacement of the mold plate 2, thereby achieving the effect of disassembling, assembling, and repairing the mold plate 2 without stopping the machine. Secondly, each time of replacement only requires replacing the mold plate 2 at the single faulty position. Its size and other factors are smaller than the overall mold, so it is convenient for personnel to disassemble and assemble, with the advantages of labor-saving and low repair difficulty. After the disassembly, assembly, and repair of the mold plate 2 are completed, the mold plate 2 on the separation component 4 is reconnected to the splicing component 3 by rotating backward, and continues to move forward to the interrupted position of the pastry punching and cutting during the rotation process. Then, the mold plate 2 is started to rotate to continue punching and cutting the pastries, and the rotation frequency of the motor controlling the mold plate 2 is increased to enable it to move backward and reset while rotating. After resetting to the initial position, the motor frequency is controlled to return to the initial state to complete the installation of the mold plate 2 without stopping the machine. When the mold plate 2 needs to be cleaned, the displacement component 5 rotates and moves the splicing component 3 to the cleaning component 6, and the cleaning of the mold plate 2 can be achieved, removing the pastries adhered to the mold plate 2, thereby avoiding problems such as pastry accumulation on the mold plate 2 affecting the quality of subsequent processed products.

[0035] As Figure 1 and Figure 5 shown, the splicing component 3 includes an insertion plate 301, a sleeve column 302, a magnet 303, and a connection disk 304. One side surface of the mold plate 2 is connected to the insertion plate 301. The cross-section of the insertion plate 301 is in an inverted L shape. A plurality of insertion holes are formed in the outer wall of the sleeve column 302 and are inserted with the insertion plate 301. Magnets 303 are arranged on both the insertion plate 301 and inside the sleeve column 302. The sleeve column 302 adsorbs the insertion plate 301 through the magnetic force of the magnet 303. The side of the sleeve column 302 is open and is connected to the connection disk 304. The connection disk 304 is provided with six sensors (not shown) for detecting the position of the insertion plate 301. The side of the connection disk 304 is perforated. The transmission shaft of the motor passes through the connection disk 304 and is connected to the sleeve column 302. The transmission shaft of the motor is rotatably connected to the connection disk 304.

[0036] Specifically, the mold plate 2 is inserted on the sleeve column 302 through the insertion plate 301, and is spliced with six mold plates 2 into a cylindrical shape. When maintenance or cleaning is required, after rotating to the specified position, the position of the mold plate 2 is detected by the sensor on the connection disk 304, and then the separation assembly 4 is activated to generate a thrust greater than the magnetic force between the magnets 303 on the mold plate 2, so that the insertion plate 301 can be detached from the sleeve column 302 to realize the separation of the mold plate 2.

[0037] Such as Figure 2 and Figure 3 shown, the separation assembly 4 includes a telescopic frame 401, a telescopic device 402 and an extraction plate 403. The telescopic frame 401 is in a frame shape. The top of the telescopic frame 401 is connected to the telescopic device 402. The extraction plate 403 is arranged at the transmission end of the telescopic device 402. The extraction plate 403 is in an L shape. An extraction groove 7 is opened on the inner wall surface of the mold plate 2 corresponding to the position of the extraction plate 403. In this embodiment, the telescopic device 402 adopts a combination of a motor and a screw. The motor is arranged on the telescopic frame 401, and the screw is connected to the transmission shaft of the motor. When the motor starts to drive the screw to rotate, the extraction plate 403 is driven to lift. In other embodiments, the telescopic device 402 can also be a linear guide rail, a telescopic cylinder, a telescopic hydraulic cylinder or other devices.

[0038] Specifically, when the mold plate 2 needs to be detached, after the mold plate 2 stops, the telescopic device 402 drives the extraction plate 403 to rise so that the extraction plate 403 is inserted into the extraction groove 7, and then further drives the extraction plate 403 to rise to generate a thrust on the mold plate 2, thereby separating the mold plate 2 from the splicing assembly 3. Through the insertion of the extraction plate 403 into the extraction groove 7, the stability of the mold plate 2 is increased when it is detached.

[0039] Such as Figure 3 、 Figure 4 and Figure 6 shown, the separation assembly 4 further includes a fixing plate 404, a threaded column 405, a toothed column 406 and a toothed plate 407. The fixing plate 404 is connected to the extraction plate 403. The fixing plate 404 is threadedly connected to the threaded column 405. The outer end of the threaded column 405 is connected to the toothed column 406. The inner wall of the telescopic frame 401 is connected to the toothed plate 407. The toothed column 406 corresponds to the position of the toothed plate 407. A positioning groove 8 corresponding to the threaded column 405 is opened on the side wall of the mold plate 2.

[0040] Specifically, when the mold plate 2 is detached from the splicing assembly 3 and descends with the extraction plate 403, the tooth column 406 meshes with the tooth plate 407 as the extraction plate 403 descends, and drives the threaded column 405 to rotate as the extraction plate 403 descends. The threaded column 405 moves on the fixed plate 404 through the threaded connection with the fixed plate 404, and then inserts into the positioning groove 8. Through the connection between the threaded column 405 and the positioning groove 8, in cooperation with the tooth plate 407, the complete limit of the mold plate 2 is achieved, avoiding displacement of the mold plate 2 at various angles. Furthermore, during the subsequent slitting and punching operations, stability is ensured, and the product quality is improved. During the re-installation operation of the mold plate 2, the tooth column 406 meshes with the tooth plate 407 again as the extraction plate 403 rises, and drives the threaded column 405 to separate from the mold plate 2. After the mold plate 2 is inserted into the splicing assembly 3, the extraction plate 403 further descends to separate from the extraction groove 7, so that the mold plate 2 is completely separated from the separation assembly 4.

[0041] As Figure 2 and Figure 4 shown, the displacement assembly 5 includes a transverse movement device 501, a rotation device 502, a semi-cylindrical bevel gear 503, a bevel gear 504, a rotating shaft 505, and a driving plate 506. The transverse movement device 501 is installed at the bottom of the assembly line conveyor belt 1. In this embodiment, the transverse movement device 501 uses a linear guide rail. In other embodiments, the transverse movement device 501 can also be a telescopic cylinder, a telescopic hydraulic cylinder, a combination of a motor and a screw, etc. The rotation device 502 is installed on the moving end of the transverse movement device 501. The rotation device 502 uses a rotation motor. The transmission shaft of the rotation device 502 is connected to the semi-cylindrical bevel gear 503. The moving end of the transverse movement device 501 tightly sleeves two rotating shafts 505 through a rotating frame. The rotating shafts 505 can rotate on the rotating frame and have a certain friction force. Moreover, the mold plate 2 adopts a lightweight structure and lightweight materials. The two rotating shafts 505 are distributed left and right relative to the semi-cylindrical bevel gear 503. The corresponding ends of the two rotating shafts 505 are connected to the bevel gear 504. The two bevel gears 504 are meshed with one side of the semi-cylindrical bevel gear 503. The left rotating shaft 505 is connected to the telescopic frame 401, and the right rotating shaft 505 is connected to the driving plate 506. The driving plate 506 is connected to the sleeve column 302.

[0042] Specifically, at the beginning of the disassembly and assembly operation, first rotate the device 502 to drive the semi-circular bevel gear 503 to rotate. When the semi-circular bevel gear 503 rotates, it meshes with a part of the bevel gear 504, and first lifts the mold plate 2 on the splicing assembly 3 to a certain height to facilitate the disassembly and assembly operation. The mold plate 2 maintains its position through the frictional force between the rotating shaft 505 and the rotating frame. After the separating assembly 4 disassembles the single mold plate 2, the rotating device 502 drives the semi-circular bevel gear 503 to continue rotating. The semi-circular bevel gear 503 meshes with the bevel gear 504 on the left side and drives the separating assembly 4 to rotate. The separating assembly 4 drives the mold plate 2 to rotate so that the inner side wall faces downwards corresponding to the assembly line conveyor belt 1, and changes the position of the single mold plate 2 by rotation to move to the interruption point of punching and slitting. At this time, the separating assembly 4 continuously lifts and lowers the mold plate 2 to continue the punching and slitting operation. Then, the semi-circular bevel gear 503 disengages from the bevel gear 504 on the left side and continues to mesh with the bevel gear 504 on the right side by rotation. Continuing to rotate the semi-circular bevel gear 503 drives the driving plate 506 to rotate, so that the semi-circular bevel gear 503 rotates to erect the splicing assembly 3 and place the splicing assembly 3 in the position of the cleaning assembly 6 for cleaning. After the maintenance or cleaning of the mold plate 2 on the splicing assembly 3 is completed, the semi-circular bevel gear 503 rotates back and moves forward through the transverse movement device 501. When the semi-circular bevel gear 503 rotates back, it first meshes with the bevel gear 504 on the right side, drives the driving plate 506 to rotate back, thereby lowering the splicing assembly 3 and the mold plate 2 on the splicing assembly 3, and moving forward to the front side of the interruption point through forward movement. Then, the rotating device 502 rotates back to mesh with the bevel gear 504 on the left side, rotates the separating assembly 4 and resets the single mold plate 2 to reconnect with the splicing assembly 3. Then, the semi-circular bevel gear 503 meshes with the bevel gear 504 on the right side again, lowers the mold plate 2 to contact the pastry, and performs punching and slitting through the rotation of the mold plate 2. During punching and slitting, increase the rotation frequency of the mold plate 2, and drive the mold plate 2 to move backward through the transverse movement device 501 to return to the initial position, and then return the rotation frequency of the mold plate 2 to the initial state, thereby completing the entire disassembly and assembly operation.

[0043] As Figure 1 shown, the cleaning assembly 6 includes a connecting frame 601, a cleaning disc 602 and a cleaning column 603. One side of the assembly line conveyor belt 1 is connected to the connecting frame 601. The top of the connecting frame 601 is connected to the cleaning disc 602. The connecting frame 601 and the driving plate 506 are arranged crosswise to avoid movement interference. The cleaning column 603 is connected to the cleaning disc 602, and brushes are provided on the outer wall of the cleaning column 603 and the lower part of the cleaning disc 602.

[0044] Specifically, during the process of the drive plate 506 rotating to the vertical state, the mold plate 2 is rotated to align the notch with the cleaning column 603. Then, after the drive plate 506 rotates to the vertical state, the mold plate 2 can be inserted into the cleaning column 603, making the inner wall of the mold plate 2 correspond to the cleaning column 603, and the outer wall of the mold plate 2 correspond to the brush on the cleaning disc 602. Then, the motor is started to drive the mold plate 2 to rotate. By the connection between the inner wall and the outer wall of the mold plate 2 and the brush during the rotation of the mold plate 2, the pastries adhered to the mold plate 2 are cleaned off, thus realizing the automatic cleaning of the mold plate 2, improving the convenience and efficiency of cleaning, and also avoiding the reduction of the punching and cutting effect caused by the adhesion and condensation of pastries on the mold plate 2 after long-term operation, thereby ensuring the overall quality of the product. The pastries cleaned from the inner wall of the mold plate 2 fall through the notch.

[0045] As Figure 2 and Figure 7 shown, the cleaning assembly 6 further includes a dust suction groove 604, a plug cylinder 605, a one-way valve 606, a sleeve 607, a plug plate 608 and a through pipe 609. Dust suction grooves 604 are opened on both the left and right sides of the lower part of the cleaning disc 602. The top surface of the dust suction groove 604 is provided with an opening. The bottom of the telescopic frame 401 is connected to the plug cylinder 605. The inner wall of the plug cylinder 605 is sleeved with the plug plate 608, and the plug plate 608 can slide in the plug cylinder 605. The bottom surface of the extraction plate 403 is connected to the sleeve 607, and the bottom end of the sleeve 607 is connected to the plug plate 608. The bottom of the plug cylinder 605 is connected to two one-way valves 606. The two one-way valves 606 can respectively input into the plug cylinder 605 and output from the plug cylinder 605. The one-way valve 606 that can input into the plug cylinder 605 is connected and communicated with the dust suction groove 604 through the through pipe 609. The through pipe 609 is made of a flexible hose, and a screen is arranged at the pipe orifice where the through pipe 609 is connected to the dust suction groove 604.

[0046] Specifically, when the extraction plate 403 drives the mold plate 2 to reciprocate up and down for punching and cutting actions, the plug plate 608 slides in the plug cylinder 605 along with the movement of the extraction plate 403 through the sleeve 607. When the plug plate 608 descends, the air in the plug cylinder 605 is squeezed out through the one-way valve 606. When the plug plate 608 rises, negative pressure is generated in the plug cylinder 605, and the negative pressure effect is transmitted to the dust suction groove 604 through the one-way valve 606 and the through pipe 609. The pastries generated and dropped during the cleaning of the mold plate 2 are sucked through the negative pressure at the top of the dust suction groove 604, avoiding the pastries from falling back onto the production line conveyor belt 1, thus preventing the quality of the products on the production line conveyor belt 1 from being damaged, and further cleaning the brushes on the cleaning disc 602 and the cleaning column 603 through the suction force, improving the service life of the brushes, and further improving the convenience of cleaning.

[0047] In summary, when the pastry is conveyed on the assembly line, the motor drives the mold plate 2 to rotate, so that the cutting teeth and punching posts on the bottom wall of the mold plate 2 come into contact with the pastry, thereby realizing cutting and punching of the pastry. When the mold plate 2 at a certain position is damaged or other problems occur and the mold plate 2 needs to be repaired and replaced, after the mold plate 2 stops, the separation component 4 detaches one mold plate 2 at the corresponding position from the splicing component 3. At this time, the pastry with interrupted cutting on the assembly line conveyor belt 1 moves to the front side of the mold plate 2. The displacement component 5 rotates the separation component 4 and drives the mold plate 2 forward to this position. The separation component 4 reciprocates up and down, so that the cutting teeth and punching posts on the plane of the mold plate 2 realize cutting and punching of the interrupted part and subsequent parts of the pastry, ensuring that the processing of the pastry will not be interrupted. It should be noted that when the separation component 4 descends, it can move a certain distance along with the pastry through the displacement component 5 and then reset when the separation component 4 ascends, so as to ensure the cutting and punching effect and avoid deforming the pastry due to side extrusion. Then, the operator can disassemble and assemble the subsequent mold plates 2 on the splicing component 3 to realize the repair and replacement of the mold plate 2, thereby achieving the effect of disassembling, assembling and repairing the mold plate 2 without stopping the machine. Secondly, only the mold plate 2 at the faulty single position needs to be replaced each time, and its size and other factors are smaller than the overall mold, so it is convenient for the operator to disassemble and assemble, with the advantages of labor saving and low repair difficulty. After the disassembly, assembly and repair of the mold plate 2 are completed, the mold plate 2 on the separation component 4 is reconnected to the splicing component 3 by rotating backward, and continues to move forward to the interrupted position of the pastry punching and cutting during the rotation process. Then, the mold plate 2 is started to rotate to continue punching and cutting the pastry, and the rotation frequency of the motor controlling the mold plate 2 is increased, so as to move backward and reset while rotating. After resetting to the initial position, the motor frequency is controlled to return to the initial state, completing the installation of the mold plate 2 without stopping the machine. When the mold plate 2 needs to be cleaned, the displacement component 5 rotates and moves the splicing component 3 to the cleaning component 6, and the cleaning of the mold plate 2 can be realized, removing the pastry adhered to the mold plate 2, thereby avoiding problems such as pastry accumulation on the mold plate 2 affecting the quality of subsequent processed products.
