Description

Technical Field

[0001] The invention relates to the technical field of food processing equipment manufacturing, in particular to a vegetarian roll cutting and spreading machine, a cutting and spreading method and a vegetarian string forming device. Background Art

[0002] Gluten skewers are a common street snack and barbecue ingredient. They usually use gluten as the main ingredient, and are seasoned and flavored with cumin powder, chili powder, salt, light soy sauce, dark soy sauce, pepper, five-spice powder, sweet noodle sauce, steamed fish soy sauce, oyster sauce, etc.

[0003] Many years ago, gluten strings were usually formed by manual preparation, which included the steps of kneading dough, letting dough rest, wrapping dough, boiling gluten and cutting gluten. The production process was complicated and required a lot of manpower costs. The production efficiency was extremely low, and the finished gluten strings had different shapes and tastes. For this reason, our company recently developed a new gluten string forming equipment.

[0004] According to the pre-designed idea, the vegetarian skewer forming equipment needs to be equipped with a vegetarian roll cutting and unfolding machine, so that the cutting, unfolding and skewering of the vegetarian rolls can be implemented to form a spiral vegetarian skewer that meets the quality acceptance standards. However, before writing this application document, no vegetarian roll cutting and unfolding machine compatible with the vegetarian skewer forming equipment was found. Therefore, it is urgent for technicians to solve the above problems. Summary of the invention

[0005] Therefore, in view of the above-mentioned existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and continued to experiment and modify the vegetarian roll cutting and unrolling machine after many years of R&D experience in this industry, which ultimately led to the emergence of the vegetarian roll cutting and unrolling machine.

[0006] The present invention relates to a vegetarian roll cutting and spreading machine, which is located downstream of a vegetarian roll receiving and feeding machine. During its operation, the vegetarian rolls fed through the vegetarian roll receiving and feeding machine complete the threading, cutting and spreading operations in sequence. The vegetarian roll cutting and spreading machine includes a load-bearing frame, a knife-closing and cutting and spreading mechanism, and a knife-retracting drive mechanism. The knife-closing and cutting and spreading mechanism and the knife-retracting drive mechanism both use the load-bearing frame as an installation basis. The knife-closing and cutting and spreading mechanism includes a front cutter assembly, a rear cutter assembly, and a first power unit. The front cutter assembly is composed of N front cutter assemblies arranged along the left and right directions and whose movements are independent. The rear cutter assembly is composed of N rear cutter assemblies that are aligned with the front cutter assembly and whose movements are independent. In a certain time period, due to the pushing force from the first power unit, multiple front cutter assemblies synchronously perform backward movement, and at the same time, multiple rear cutter assemblies synchronously perform forward movement to complete the knife closing action, or, in another time period, due to the dragging force from the knife retraction drive mechanism, each front cutter assembly performs the forward movement and retreat action in turn, and at the same time, the rear cutter assembly opposite thereto performs the backward movement and retreat action in turn, and the above actions are repeated until all the front cutter assemblies and the rear cutter assemblies are retracted.

[0007] As a further improvement of the technical solution disclosed in the present invention, the first power unit includes a front push member, a rear push member, a force transmission mechanism and a first motor. The front push member is only used to apply a push force to the front cutter set and eliminate the drag force. The rear push member is only used to apply a push force to the rear cutter set and eliminate the drag force. The first motor uses the load-bearing frame as an installation base, and uses the force transmission mechanism to drive the front push member and the rear push member to synchronously perform a displacement movement toward / away from each other.

[0008] As a further improvement of the technical solution disclosed in the present invention, the force transmission mechanism is composed of a primary gear rack force transmission mechanism, a front secondary gear rack force transmission mechanism and a rear secondary gear rack force transmission mechanism. During the operation of the first motor, the torque output by the first motor is distributed in equal proportion to the front secondary gear rack force transmission mechanism and the rear secondary gear rack force transmission mechanism via the primary gear rack force transmission mechanism.

[0009] As a further improvement of the technical solution disclosed in the present invention, the primary gear rack force transmission mechanism includes a primary gear and a primary rack. The front secondary gear rack force transmission mechanism includes a front secondary driving gear, a front secondary driven gear, and a front secondary rack welded as one with the front ejector. The rear secondary gear rack force transmission mechanism includes a rear secondary driving gear, a rear secondary driven gear, and a rear secondary rack welded as one with the rear ejector. The primary gear is used to directly drive the primary rack, which is mounted on the power output shaft of the first motor. The front secondary driving gear is meshed with the primary rack, and it cooperates with the front secondary driven gear to drive the front secondary rack. The rear secondary driving gear is also meshed with the primary rack, and it cooperates with the rear secondary driven gear to drive the rear secondary rack. During the period when the primary rack performs displacement movement due to the meshing force from the primary gear, the rotation directions of the front secondary driving gear and the rear secondary driving gear are different; and after the front cutter assembly and the rear cutter assembly complete the knife closing action and the vegetarian roll is cut, the first motor rotates in the opposite direction, the front ejector disengages from the front cutter assembly by a set distance, and each front cutter assembly has the freedom of displacement along the front and rear directions. At the same time, the rear ejector disengages from the rear cutter assembly by a set distance, and each rear cutter assembly has the freedom of displacement along the front and rear directions.

[0010] As a further improvement of the technical solution disclosed in the present invention, the knife retracting drive mechanism includes a front connecting rod mechanism set, a rear connecting rod mechanism set, a driving plate set, an eccentric wheel assembly and a second power unit. The front connecting rod mechanism set and the rear connecting rod mechanism set are respectively used to drive the front cutter assembly and the rear cutter assembly to perform the knife retracting action in a one-to-one correspondence, and both use the load-bearing frame as an articulated installation basis. The eccentric wheel assembly and the second power unit both use the load-bearing frame as an installation basis. During the operation of the second power unit, the eccentric wheel assembly performs a circumferential rotation motion, and the driving plate assembly performs a downward movement due to the direct action of the pressing force set from the eccentric wheel assembly. At the same time, the front connecting rod mechanism set and the rear connecting rod mechanism set are deflected in the opposite direction due to the dragging force from the driving plate assembly, so that the front cutter assembly and the rear cutter assembly can complete the knife retracting action.

[0011] As a further improvement of the technical solution disclosed in the present invention, the front connecting rod mechanism set is composed of a set of N front connecting rod mechanisms arranged along the left and right directions and whose movements are independent. The rear connecting rod mechanism set is composed of a set of N rear connecting rod mechanisms arranged along the left and right directions and whose movements are independent. The drive plate set is composed of a set of N drive plates arranged along the left and right directions and whose movements are independent. The eccentric wheel assembly includes a rotating shaft and N eccentric cams. The rotating shaft performs circumferential rotational motion due to the rotational torque from the second power unit. Each eccentric cam uses the rotating shaft as a set and fixed basis, and the design appearance and assembly phase angle are different. During the operation of the second power unit, each eccentric cam follows the rotating shaft to perform circumferential rotational motion synchronously. At the same time, the downward movement process of each drive plate is different, and the corresponding front connecting rod mechanism and rear connecting rod mechanism perform yaw motion in opposite directions.

[0012] As a further improvement of the technical solution disclosed in the present invention, the front connecting rod mechanism and the rear connecting rod mechanism have the same design structure. The front connecting rod mechanism includes a front swinging member and a front side thrust member. The front swinging member is assembled in the inner cavity of the load-bearing frame in an articulated manner, and serves as the insertion base of the front side thrust member. A first front sliding cavity adapted to the front side thrust member is provided on the front swinging member at a set distance from its front end surface. A second front sliding cavity adapted to the front side thrust member is provided on the front cutter assembly. During the downward movement of the driving plate, the front swinging member performs a deflection movement due to the action of the driving force. At the same time, the two free ends of the front side thrust member slide freely in the first front sliding cavity and the second front sliding cavity respectively and one by one, and the front cutter assembly performs a translational retraction action due to the action of the side thrust from the front side thrust member.

[0013] As a further improvement of the technical solution disclosed in the present invention, the driving plate adopts a meshing transmission mode to drive the front connecting rod mechanism and the rear connecting rod mechanism. The front side wall of the driving plate is formed with front continuous gear teeth, and correspondingly, the front swinging member is formed with a front arc gear segment adapted to the front continuous gear teeth.

[0014] Furthermore, the technical solution of the present invention also discloses a vegetarian roll cutting and spreading method, which is implemented by means of the above-mentioned vegetarian roll cutting and spreading machine, and includes the following steps:

[0015] S1, after the vegetarian roll is fed into the vegetarian roll cutting and spreading machine, due to the push force from the first power unit, multiple front cutter assemblies synchronously perform backward movement, and at the same time, multiple rear cutter assemblies synchronously perform forward movement to complete the initial knife closing action, and the circumferential side wall of the vegetarian roll is clamped and constrained due to multiple groups of radial restraining forces;

[0016] S2, the skewer is supplied to the vegetarian roll cutting and spreading machine and inserted into the vegetarian roll to a set depth value;

[0017] S3, due to the push force from the first power unit again, the multiple front cutter assemblies continue to synchronously perform the backward movement, and at the same time, the multiple rear cutter assemblies continue to synchronously perform the forward movement, so as to complete the final knife closing action, and a series of cutting slits are formed on the circumferential side wall of the vegetarian roll, and the front cutter assemblies and the rear cutter assemblies do not damage the skewers;

[0018] S4. Due to the dragging force from the retraction drive mechanism, each front cutter assembly performs the forward movement and retreat action in sequence. At the same time, the rear cutter assembly opposite to it performs the backward movement and retreat action in sequence. During this process, multiple cutting slits are able to have axial extension freedom in sequence, and they are gradually expanded due to the indirect tensile force of the skewers, until the spiral vegetarian skewer is completely removed from the vegetarian roll cutting and unfolding machine.

[0019] In addition, the technical solution of the present invention also discloses a vegetarian skewer forming device, which includes the above-mentioned vegetarian roll cutting and unfolding machine.

[0020] For vegetarian roll cutting and spreading machinery and vegetarian string forming equipment, in practical application, at least the following beneficial technical effects can be achieved, specifically:

[0021] 1) Multiple front cutter assemblies and rear cutter assemblies can synchronously perform backward and forward movement to complete the knife closing action, so that all cuts can be formed on the vegetarian roll at one time, which can greatly improve the efficiency of vegetarian roll cutting and spreading, so that more vegetarian rolls can be processed in a unit time to meet the needs of large-scale production;

[0022] 2) Each front cutter assembly and rear cutter assembly performs the retraction action in sequence, and in this process, multiple cut slits are able to have axial extension freedom in sequence, and they are gradually extended due to the indirect tensile force of the skewers. In addition, the retraction operation process of each front cutter assembly and rear cutter assembly (including retraction speed, retraction limit position and other parameters) can be accurately controlled by the retraction drive mechanism, which is conducive to ensuring the consistency of the extension action and extension amount of the cut slits on the vegetarian roll;

[0023] 3) Thanks to the independent design of the movement of the front cutter assembly and the rear cutter assembly, even if a single front cutter assembly or a rear cutter assembly fails, it will not affect the normal operation of other components, and it is easy to quickly locate and replace the faulty components, reducing maintenance costs and downtime, and improving the reliability and durability of the entire mechanism;

[0024] 4) The vegetarian roll cutting and unfolding machine combines the functions of cutting, unfolding and threading vegetarian rolls, which can save manual operation, greatly improve production efficiency, and help realize the automated assembly line production of vegetarian skewer forming equipment.

[0025] With regard to the vegetarian roll cutting and spreading method, it can achieve at least the following beneficial technical effects in practical application, specifically:

[0026] 1) The vegetarian roll is stably and reliably restrained by the radial restraining force from the multiple groups of front cutter assemblies and the rear cutter assemblies. Thus, on the one hand, the occurrence of non-centering or tilted insertion of the skewer can be effectively avoided, ensuring that the skewer can be inserted into the vegetarian roll in a centering and concentric manner; on the other hand, the axial compression of the vegetarian roll is always controlled within a reasonable value range during the process of being skewered, which can effectively avoid the occurrence of local bulging of the vegetarian roll due to the skewering force;

[0027] 2) After the cuts on the vegetarian roll are formed, the front cutter assembly and the rear cutter assembly are not completely out of the cuts. In addition, during the process of the vegetarian roll being formed, each front cutter assembly and the rear cutter assembly gradually perform the knife retreat action and completely out of the cuts, and each cut can be formed in sequence. The formed vegetarian skewers have excellent stretch consistency in each segment, and the shape is regular and the thickness is uniform, which is conducive to the smooth implementation of the subsequent seasoning and flavoring process and baking process.

DETAILED DESCRIPTION

[0047] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "left", "right", "front", "back", "up", "down", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0048] The present invention will be further described in detail below with reference to specific embodiments. Figure 1The schematic diagram of the structure of the vegetarian skewer forming equipment disclosed in the present invention is shown. It can be seen that it is mainly composed of a machine 1, a vegetarian roll supply machine 2, a vegetarian roll horizontal conveying machine 3, a vegetarian roll receiving and feeding machine 4, a vegetarian roll cutting and unfolding machine 5, a skewer supply machine 6, a skewer pushing machine (not shown in the figure) and a vegetarian skewer removing machine 7. Among them, the machine 1 is placed horizontally and in a horizontal state, and is used as the overall installation base. The vegetarian roll supply machine 2, the skewer supply machine 6, and the vegetarian roll cutting and unfolding machine 5 are all located directly behind the vegetarian roll horizontal conveying machine 3, and are arranged in sequence from right to left. The skewer pushing machine is used to match the skewer supply machine 6, and is hidden under the skewer supply machine 6. The vegetarian roll receiving and feeding machine 4 is located on the left side of the vegetarian roll cutting and unfolding machine 5, and is used to receive the vegetarian rolls transported by the vegetarian roll horizontal conveying machine 3, and transfer them to the vegetarian roll cutting and unfolding machine 5. During the operation of the vegetarian roll cutting and unfolding machine 5, the vegetarian rolls fed through the vegetarian roll receiving and feeding machine 4 are sequentially threaded, cut and unfolded. The vegetarian string removal machine 7 is used to match the vegetarian roll cutting and unfolding machine 5, which is used to receive the finished vegetarian string, and the left wall of the vegetarian roll cutting and unfolding machine 5 is used as the installation base.

[0049] Figure 2 , Figure 3 , Figure 4 The structure diagram of the vegetarian roll cutting and spreading machine disclosed in the present invention is shown together. It can be seen that the vegetarian roll cutting and spreading machine 5 is mainly composed of a load-bearing frame 51, a knife closing and cutting and spreading mechanism 52, and a knife retreating driving mechanism 53. Among them, the load-bearing frame 51 is placed on the machine table 1 and is fixed in a detachable manner. The knife closing and cutting and spreading mechanism 52 and the knife retreating driving mechanism 53 are both installed on the load-bearing frame 51. Figure 5As shown in the figure, the knife closing and cutting mechanism 52 includes a front knife assembly 521, a rear knife assembly 522 and a first power unit 523. The front knife assembly 521 is composed of N front knife assemblies 5211 arranged in the left and right directions and having independent movement movements. The rear knife assembly 522 is composed of N rear knife assemblies 5221 that are aligned with the front knife assembly 5211 and have independent movement movements. During the operation of the vegetarian roll cutting and unfolding machine, in a certain time period, due to the pushing force from the first power unit 523, multiple front cutter components 5211 synchronously perform backward movement, and at the same time, multiple rear cutter components 5221 synchronously perform forward movement to complete the knife closing action, or, in another time period, due to the dragging force from the knife retraction drive mechanism 53, each front cutter component 5211 performs forward and retreat action in turn, and at the same time, the rear cutter component 5221 opposite thereto performs backward and retreat action in turn, and the cutting slit opposite thereto is able to have axial extension freedom, and it is able to expand due to the indirect tensile force of the skewer, and the above actions are repeated. As the retraction process of the front cutter component 5211 and the rear cutter component 5221 continues, the spiral vegetarian string is gradually formed.

[0050] By adopting the above-mentioned technical scheme, on the one hand, multiple front cutter components 5211 and rear cutter components 5221 can synchronously perform backward and forward movements to complete the knife closing action, so that all cutting slits can be formed on the vegetarian roll at one time, which can greatly improve the cutting and unfolding efficiency of the vegetarian roll, so that it can process more vegetarian rolls per unit time and meet the needs of large-scale production; on the other hand, each front cutter component 5211 and rear cutter component 5221 performs the retracting action in turn, and in this process, multiple cutting slits are able to have axial extension freedom in sequence, and they are gradually extended due to the indirect tensile force of the skewers; on the other hand, thanks to the independent design characteristics of the movement of the front cutter component 5211 and the rear cutter component 5221, even if individual front cutter components 5211 or rear cutter components 5221 fail, it will not affect the normal operation of other components, and it is convenient to quickly locate and replace the faulty components, reducing maintenance costs and downtime, and improving the reliability and durability of the entire mechanism.

[0051] Here, it should be emphasized that the vegetarian roll cutting and unfolding machine 5 combines the cutting, unfolding and skewering functions of the vegetarian roll, which can save manual operation, greatly improve production efficiency, and help realize the automated assembly line production of vegetarian skewer forming equipment.

[0052] In order to ensure that the vegetarian roll cutting and spreading machine 5 can fully exert its working performance and ensure that the cutting and spreading process can be smoothly implemented, it is required that during the working period of the first power unit 523, the front cutter set 521 and the rear cutter set 522 must have excellent displacement consistency. In view of this, as a further refinement of the above technical solution, Figures 6 to 9 As shown in the figure, the first power unit 523 is mainly composed of a front push member 5231, a rear push member 5232, a force transmission mechanism 5233 and a first motor 5234. Among them, the front push member 5231 is only used to apply a push force to the front cutter assembly 521 and eliminate the drag force. The rear push member 5232 is only used to apply a push force to the rear cutter assembly 522 and eliminate the drag force. The first motor 5234 is installed on the load-bearing frame 51, and in a certain period of time, with the help of the force transmission mechanism 5233, it drives the front push member 5231 and the rear push member 5232 to synchronously perform the opposite displacement movement, so that the front cutter set 521 and the rear cutter set 522 can achieve the knife closing action; in another period of time, with the help of the force transmission mechanism 5233, it drives the front push member 5231 and the rear push member 5232 to synchronously perform the opposite displacement movement, so that the front cutter set 521 and the rear cutter set 522 can lose the supporting force and be maintained on the free motion table, paving the way for the subsequent knife retracting action.

[0053] Furthermore, the same Figures 6 to 9It can also be clearly seen that the force transmission mechanism 5233 is composed of a primary gear rack force transmission mechanism 52331, a front secondary gear rack force transmission mechanism 52332 and a rear secondary gear rack force transmission mechanism 52333. The primary gear rack force transmission mechanism 52331 includes a primary gear 523311 and a primary rack 523312. The front secondary gear rack force transmission mechanism 52332 includes a front secondary driving gear 523321, a front secondary driven gear 523322 and a front secondary rack 523323 welded to the front ejection member 5231. The rear secondary gear rack force transmission mechanism 52333 includes a rear secondary driving gear 523331, a rear secondary driven gear 523332 and a rear secondary rack 523333 welded to the rear ejection member 5232. The primary gear 523311 is used to directly drive the primary rack 523312, which is mounted on the power output shaft of the first motor 5234. The front secondary driving gear 523321 is meshed with the primary rack 523312, and cooperates with the front secondary driven gear 523322 to drive the front secondary rack 523323. The rear secondary driving gear 523331 is also meshed with the primary rack 523312, and cooperates with the rear secondary driven gear 523332 to drive the rear secondary rack 523333. When the primary rack 523312 performs displacement motion due to the meshing force from the primary gear 523311, the rotation directions of the front secondary driving gear 523321 and the rear secondary driving gear 523331 are different.

[0054] During the operation of the first motor 5234, the torque outputted by the first motor 5234 is proportionally distributed to the front second gear rack force transmission mechanism 52332 and the rear second gear rack force transmission mechanism 52333 via the first gear rack force transmission mechanism 52331. It is particularly important to explain that after the front cutter set 521 and the rear cutter set 522 complete the knife closing action and the vegetarian roll is cut, the first motor 5234 rotates in the opposite direction, the front push member 5231 disengages the front cutter set 521 by a set distance, and each front cutter assembly 5211 has a displacement freedom along the front-back direction. At the same time, the rear push member 5232 disengages the rear cutter set 522 by a set distance, and each rear cutter assembly 5221 has a displacement freedom along the front-back direction.

[0055] As is known, according to design common sense, the knife retraction drive mechanism 53 can adopt a variety of design structures to realize the knife retraction drive of the front knife set 521 and the rear knife set 522. However, here, a scheme with a simple design structure, easy manufacturing and implementation, and convenient subsequent maintenance operation is recommended, specifically: Figures 10-12As shown in , it can be known that the knife retracting drive mechanism 53 is mainly composed of a front connecting rod assembly 531, a rear connecting rod assembly 532, a drive plate assembly 533, an eccentric wheel assembly 534 and a second power unit 535. Among them, the front connecting rod assembly 531 and the rear connecting rod assembly 532 are used to drive the front cutter assembly 521 and the rear cutter assembly 522 to perform the knife retracting action in a one-to-one correspondence, and both use the bearing frame 51 as an articulated installation foundation. The eccentric wheel assembly 534 and the second power unit 535 both use the bearing frame 51 as an installation foundation. During the operation of the second power unit 535, the eccentric wheel assembly 534 performs a circumferential rotation movement, and the driving plate assembly 533 performs a downward movement due to the direct pressure force from the eccentric wheel assembly 534. At the same time, the front connecting rod assembly 531 and the rear connecting rod assembly 532 are deflected in the opposite direction due to the drag force from the driving plate assembly 533, and the front cutter assembly 521 and the rear cutter assembly 522 are able to complete the retraction action. In practical applications, the retraction operation process (including retraction speed, retraction limit position and other parameters) of each front cutter assembly 5211 and the rear cutter assembly 5221 can be accurately controlled by means of the retraction drive mechanism 53, which is conducive to ensuring the consistency of the extension action and extension amount of the cut slit on the vegetarian roll.

[0056] Furthermore, by Fig.10 As shown in the figure, it can be clearly seen that the front connecting rod mechanism assembly 531 is composed of N front connecting rod mechanisms 5311 arranged in the left-right direction and with independent movement movements. The rear connecting rod mechanism assembly 532 is composed of N rear connecting rod mechanisms 5321 arranged in the left-right direction and with independent movement movements. The drive plate assembly 533 is composed of N drive plates 5331 arranged in the left-right direction and with independent movement movements. The eccentric wheel assembly 534 includes a rotating shaft 5341 and N eccentric cams 5342. The rotating shaft 5341 performs circumferential rotation due to the rotational torque from the second power unit 535. Each eccentric cam 5342 is mounted and fixed on the rotating shaft 5341, and the design appearance and assembly phase angle are different. During the operation of the second power unit 535, each eccentric cam 5342 synchronously performs circumferential rotation motion following the rotating shaft 5341. At the same time, the downward movement process of each driving plate 5331 is different, and the corresponding front connecting rod mechanism 5311 and rear connecting rod mechanism 5321 perform eccentric motion in opposite directions. At the same time, the front cutter assembly 5211 relative to the front connecting rod mechanism 5311 and the rear cutter assembly 5221 relative to the rear connecting rod mechanism 5321 perform a retracting action until they are completely out of the cutting seam.

[0057] As Fig.12As shown in , the front connecting rod mechanism 5311 includes a front swing member 53111 and a front side thrust member 53112. The front swing member 53111 is assembled in the inner cavity of the load-bearing frame 51 in an articulated manner, and serves as the insertion basis of the front side thrust member 53112. A first front sliding cavity 531111 adapted to the front side thrust member 53112 is provided on the front swing member 53111 at a set distance from its front end surface. A second front sliding cavity 52111 adapted to the front side thrust member 53112 is provided on the front cutter assembly 5211. The rear connecting rod mechanism 5321 includes a rear swing member 53211 and a rear side thrust member 53212. The rear swing member 53211 is also assembled in the inner cavity of the load-bearing frame 51 in an articulated manner, and serves as the insertion basis of the rear side thrust member 53212. A first rearward sliding cavity 532111 adapted to the rearward side thrust member 53212 is provided on the rearward swing member 53211 at a set distance from the rearward side surface. A second rearward sliding cavity 52211 (such as Figures 13-16 ). During the downward movement of the driving plate 5331, the front swinging member 53111 and the rear swinging member 53211 perform a reverse deflection movement due to the driving force, and the two free ends of the front side thrust member 53112 slide freely in the first front sliding cavity 531111 and the second front sliding cavity 52111 respectively and one by one. At the same time, the two free ends of the rear side thrust member 53212 slide freely in the first rear sliding cavity 532111 and the second rear sliding cavity 52211 respectively and one by one. The front cutter assembly 5211 and the rear cutter assembly 5221 opposite to them perform a reverse displacement movement due to the reverse side thrust from the front side thrust member 53112 and the rear side thrust member 53212 respectively, and the knife retracting action is realized.

[0058] Furthermore, if Fig.10 As shown in , the driving plate 5331 preferably adopts a meshing transmission mode to drive the front connecting rod mechanism 5311 and the rear connecting rod mechanism 5321. The front and rear side walls of the driving plate 5331 are respectively formed with front continuous gear teeth 53311 and rear continuous gear teeth 53312. Correspondingly, the front swinging member 53111 is formed with a front arc gear segment 531112 adapted to the front continuous gear teeth 53311, and the rear swinging member 53211 is formed with a rear arc gear segment 532112 adapted to the rear continuous gear teeth 53312. In this way, on the one hand, under the premise of ensuring that the knife retracting action is smoothly realized, the knife retracting driving mechanism 53 has a relatively simple design structure, is easy to manufacture and implement, and is convenient for maintenance and repair operations in the later stage; on the other hand, compared with other force transmission modes, the meshing transmission mode has relatively high transmission efficiency and transmission accuracy.

[0059] The technical solution of the present invention also discloses a vegetarian roll cutting and spreading method, which is implemented by means of the vegetarian roll cutting and spreading machine 5, and includes the following steps:

[0060] S1, after the vegetarian roll is fed into the vegetarian roll cutting and spreading machine 5, due to the pushing force from the first power unit 523, the multiple front cutter assemblies 5211 synchronously perform backward movement, and at the same time, the multiple rear cutter assemblies 5221 synchronously perform forward movement to complete the initial knife closing action, and the circumferential side wall of the vegetarian roll is clamped and constrained due to multiple groups of radial restraining forces;

[0061] S2, the skewer is supplied to the vegetarian roll cutting and spreading machine 5, and inserted into the vegetarian roll to a set depth value;

[0062] S3. Due to the pushing force from the first power unit 523 again, the multiple front cutter assemblies 5211 continue to synchronously perform the backward movement, and at the same time, the multiple rear cutter assemblies 5221 continue to synchronously perform the forward movement, so as to complete the final knife closing action, and a series of cutting slits are formed on the circumferential side wall of the vegetarian roll, and the front cutter assemblies 5211 and the rear cutter assemblies 5221 do not damage the skewers;

[0063] S4. Due to the dragging force from the retraction drive mechanism 53, each front cutter assembly 5211 performs a forward movement and retreat action in sequence. At the same time, the rear cutter assembly 5221 opposite thereto performs a backward movement and retreat action in sequence. During this process, multiple cutting slits are able to have axial extension freedom in sequence, and they are gradually expanded due to the indirect tensile force of the skewers, until the spiral vegetarian string is completely removed from the vegetarian roll cutting and unfolding machine.

[0064] In practical applications, the above vegetarian roll cutting and spreading method has achieved the following beneficial technical effects, specifically:

[0065] 1) The vegetarian roll is stably and reliably restrained by the radial restraining force from the multiple groups of front cutter assemblies 5211 and the rear cutter assemblies 5221. Thus, on the one hand, the occurrence of non-centering or tilted insertion of the skewer can be effectively avoided, ensuring that the skewer can be inserted into the vegetarian roll in a centering and concentric manner; on the other hand, the axial compression amount of the vegetarian roll is always controlled within a reasonable value range during the process of being skewered, which can effectively avoid the occurrence of local bulging of the vegetarian roll due to the skewering force;

[0066] 2) After the cuts on the vegetarian roll are formed, the front cutter assembly 5211 and the rear cutter assembly 5221 are not completely out of the cuts. In addition, during the process of the vegetarian roll being formed, the front cutter assembly 5211 and the rear cutter assembly 5221 gradually perform the knife withdrawal action and completely out of the cuts, and the cuts are formed in sequence. The formed vegetarian skewers have excellent stretch consistency, regular shape, and uniform thickness, which is conducive to the subsequent smooth implementation of the seasoning and baking process.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
