Technical Field
[0001] This utility model relates to the field of food processing technology, specifically a food cake stacking machine. Background Technology
[0002] Erkuai, a traditional specialty food, has a long history and a wide market demand. The traditional Erkuai making process mainly relies on manual operation, including pressing steamed rice into blocks, and then cutting them into slices by hand for sale or further processing. With the continuous growth of market demand and the improvement of food safety standards, the manual production method can no longer meet the requirements of modern production.
[0003] Currently, there are some bait cutting equipment on the market, which mainly adopt simple mechanical cutting methods. Existing bait cutting equipment usually includes fixed cutting blades and simple conveying devices. It cuts the bait strips by mechanical force. Some equipment is also equipped with basic collection devices to collect the cut bait pieces.
[0004] Traditional bait cutting equipment has the following shortcomings: First, the cutting efficiency is low. Due to the use of ordinary mechanical cutting methods, the cutting resistance is high, which easily causes the bait to deform or break. Second, the product quality is unstable. During the cutting process, the bait is easy to stick to the blade, affecting the flatness of the cut surface and the consistency of the slice thickness. Third, the function is limited. It can only realize basic cutting functions and cannot meet the needs of modern food processing for product diversification and exquisite appearance. Fourth, the degree of automation is low. It requires a lot of manual labor, which is labor-intensive and limits production efficiency.
[0005] Existing bait cutting equipment is mainly designed to meet basic cutting needs, using the up-and-down movement of mechanical blades to divide bait strips. However, it still has certain limitations, such as severe adhesion during the cutting process, low cutting efficiency, inability to achieve surface pattern decoration, insufficient equipment stability, and limited automation. These problems seriously restrict the large-scale and standardized development of the bait industry.
[0006] Therefore, there is an urgent need for a new type of bait stacking machine that integrates high-efficiency cutting, anti-sticking treatment, pattern molding, and automatic stacking to meet the technical requirements and market demands of modern bait production. Summary of the Invention

[0010] Both the rear conveying mechanism and the front conveying mechanism include symmetrically arranged lifting cylinders. The ends of the two lifting cylinders that are close to each other are fixedly connected to lifting brackets. Rollers 1, 2, and 3 are rotatably connected between the two lifting brackets. A telescopic fixed bracket is fixedly connected between the two lifting brackets near roller 3. Two telescopic hydraulic cylinders are fixedly connected to the telescopic fixed bracket. The ends of the telescopic hydraulic cylinders that are away from roller 3 are fixedly connected to a telescopic bracket. Telescopic rollers 1 and 2 are rotatably connected to the telescopic bracket. The outer ends of rollers 1, 2, 3, and telescopic rollers 1 and 2 are provided with the same conveyor belt.
[0011] The vibrating strip is a piezoelectric stack made of piezoelectric material. The strain direction of the piezoelectric stack is the tangential direction of the driving ring. One end of the vibrating strip is fixedly connected to the bracket.
[0012] A connecting rod is fixedly connected to the top of the molding plate, and the connecting rod passes through the vibrating plate upwards. A limit block is fixedly connected to the top of the connecting rod.
[0013] The bottom of the molding plate is clamped with a mold, and the bottom of the cutting ring has a wedge-shaped structure. Both the cutting ring and the mold are coated with a hydrophobic coating.
[0014] A baffle is fixedly connected to the top of the telescopic support. The axes of roller one and roller two are located on the same horizontal plane, and the axes of roller three and telescopic roller one are located on the same horizontal plane.
[0015] Telescopic roller 2 is located between roller 1 and telescopic roller 1. The cylinder body of the telescopic hydraulic cylinder is fixedly connected to the telescopic fixed bracket, and the piston rod of the telescopic hydraulic cylinder is fixedly connected to the telescopic bracket.
[0016] The cylinder body of the lifting cylinder is fixedly connected to the base, the piston rod of the lifting cylinder is fixedly connected to the lifting bracket, and a motor is fixedly connected to the lifting bracket at the position corresponding to the second roller.
[0017] The motor drive shaft is fixedly connected to the second roller. The axes of the second and third rollers are located in the same vertical plane. The lifting support is a triangular structure.
[0018] The lifting support has a clearance groove at the corresponding position of the telescopic support. The cutting cylinder, lifting cylinder and telescopic hydraulic cylinder are all double-acting cylinders and are all electrically connected to the external control system. A tray is fixedly connected between the rear conveying mechanism and the front conveying mechanism.
[0019] The beneficial effects of this utility model are:
[0020] The reciprocating motion provided by the cutting cylinder is characterized by controllable force and precise stroke, which can adapt to the cutting needs of bait strips of different thicknesses and hardnesses. The bracket, as a stable carrier of the cutting components, ensures precise cooperation and reliable connection between various cutting parts. The drive ring is a ring structure design composed of multiple vibration bars, which can generate a uniformly distributed high-frequency vibration field, making the cutting process smoother and more efficient. The vibration plate collects and transmits the energy of various vibration sources in a unified manner, ensuring the consistency and stability of vibration output.
[0021] The vibrating bar uses a piezoelectric stack made of piezoelectric material, which has the advantages of fast response speed, high control precision, and stable vibration frequency. The innovative design of setting the strain direction of the piezoelectric stack to the tangential direction of the drive ring can generate a ring-shaped high-frequency vibration field in the drive ring, so as to maximize the utilization of vibration energy. Under the action of high-frequency vibration, the cutting ring can significantly reduce the cutting resistance and improve the cutting efficiency. At the same time, it can effectively prevent the bait material from sticking to the cutting surface, ensuring the consistency and stability of the cutting quality. The wedge-shaped bottom design of the cutting ring further reduces the cutting resistance, making the cutting process easier and smoother.
[0022] The sliding connection design of the molding plate within the cutting ring allows it to flexibly adapt to variations in the thickness of different bait blocks, ensuring consistent molding results. The combination of connecting rods and limiting blocks provides precise position control and stable guidance for the molding plate, guaranteeing the accuracy and repeatability of the molded pattern. The return spring provides reliable return force for the molding plate, ensuring the integrity of each molding action. Multiple micro-holes on the molding plate, combined with the negative pressure tube and external negative pressure system, form a complete negative pressure adsorption system, which firmly adheres the molding plate to the bait block, eliminating air gaps and ensuring the clarity and consistency of the pattern imprint. The snap-fit design of the mold makes changing different patterns simple and quick, greatly improving production flexibility.
[0023] The hydrophobic coating applied to the cutting ring and mold surface has excellent anti-sticking properties, effectively preventing bait material residue from remaining on the cutting and molding surfaces, keeping the equipment surface clean, reducing cleaning and maintenance workload, and extending the service life of the cutting ring and mold, reducing equipment operating costs and improving economic efficiency.
[0024] The lifting cylinders are symmetrically arranged front and rear to ensure the smoothness and synchronization of the lifting movement, avoiding equipment failure caused by uneven lifting. The lifting support adopts a triangular structure design, which is lightweight, high-strength, and rigid, and can withstand large loads while ensuring the accuracy of the lifting movement. The triangular arrangement of the roller assembly provides good support and guidance for the conveyor belt, ensuring the stability of the conveyor belt operation. The direct connection between the motor power shaft and the rollers eliminates energy loss in the transmission link, improving transmission efficiency and control accuracy.
[0025] The telescopic fixed bracket provides a stable base for the telescopic mechanism. The parallel design of the dual-cylinder telescopic hydraulic cylinder provides sufficient telescopic power and good synchronization. The movable design of the telescopic bracket allows the end of the conveyor belt to be flexibly adjusted as needed, realizing a smooth transition of the bait strip between different conveying mechanisms. The reasonable arrangement of the telescopic rollers provides effective support for the conveyor belt during the telescopic process, preventing deformation and damage to the conveyor belt.
[0026] The cutting cylinder, lifting cylinder, and telescopic hydraulic cylinder all adopt double-acting cylinders, which are characterized by precise action, rapid response, and high reliability. All actuators are electrically connected to the external control system, which can realize precise timing control and parameter adjustment, meeting the requirements of modern production for automation and intelligence. The control system can also precisely control the vibration parameters of the piezoelectric stack, realizing the optimization and personalized customization of the cutting process.
[0027] The baffle effectively protects the conveyor belt from damage during the cutting process, extending its service life. The clearance groove avoids interference between moving parts, improving the safety and reliability of equipment operation. The tray provides a reliable collection platform for the cut bait pieces, preventing product spillage and damage.
[0028] The equipment achieves fully automated production of bait strips, including automatic conveying, efficient cutting, exquisite molding, and orderly stacking. This significantly improves production efficiency, reduces labor costs, and the application of high-frequency vibration cutting technology greatly increases cutting speed while ensuring the stability of cutting quality. The addition of molding pattern functions significantly enhances product added value and strengthens market competitiveness. The high degree of automation and intelligence of the equipment reduces the skill requirements for operators, lowers training costs, and reduces operational risks. Attached Figure Description

[0042] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0043] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.
[0044] Example 1:
[0045] like Figures 1 to 11 As shown in the figure, this embodiment provides a bait stacking machine, which can realize automatic feeding, precise cutting and orderly stacking of bait strips, and meet the basic requirements of bait processing.
[0046] The bait stacking machine includes a base, which provides a stable support foundation for the entire equipment. A rear conveying mechanism 1 and a front conveying mechanism 2 are fixedly connected to the base, arranged symmetrically on the left and right. This symmetrical layout design ensures the structural balance and operational stability of the equipment. A cutting mechanism 3 is provided on the upper side of the front conveying mechanism 2. The cutting mechanism 3 is located directly above the front conveying mechanism 2, which facilitates the cutting operation of the bait strips conveyed by the front conveying mechanism 2. The bait strips to be cut are placed at the top of the rear conveying mechanism 1 and the front conveying mechanism 2. The bait strips span between the two conveying mechanisms, preparing for subsequent cutting and stacking operations.
[0047] The cutting mechanism 3 includes a cutting cylinder 4 fixedly connected to the base. The cutting cylinder 4 provides the power source for the cutting mechanism 3 to reciprocate up and down. A bracket 5 is fixedly connected to the bottom end of the cutting cylinder 4. The bracket 5 serves as the carrier of the cutting components, ensuring the stable connection of each cutting part. A drive ring 6 is fixedly connected to the bottom end of the bracket 5. The drive ring 6 consists of multiple vibrating strips. These vibrating strips are arranged in a ring around the bottom end of the bracket 5, providing a basis for subsequent vibration transmission. The ends of the multiple vibrating strips away from the bracket 5 are fixedly connected to the same vibrating plate 7. The vibrating plate 7 collects and transmits the vibrations generated by each vibrating strip. A cutting ring 8 is threadedly connected to the bottom end of the vibrating plate 7. The cutting ring 8 can be firmly fixed on the vibrating plate 7, and is easy to disassemble and replace. A molding plate 9 is slidably connected inside the cutting ring 8. The molding plate 9 can slide freely in the axial direction inside the cutting ring 8 to realize the molding function of the bait. A return spring 10 is fixedly connected between the vibrating plate 7 and the molding plate 9. The return spring 10 provides a downward restoring force for the molding plate 9. Multiple micro-holes are opened on the molding plate 9 along its axial direction. These micro-holes penetrate the entire thickness of the molding plate 9 to provide a channel for the action of the negative pressure system. A negative pressure pipe 11 is fixedly connected to the top of the vibrating plate 7. The negative pressure pipe 11 is connected to the external negative pressure system through a pipe to provide negative pressure power for the adsorption and fixation of the molding plate 9.
[0048] Both the rear conveying mechanism 1 and the front conveying mechanism 2 include symmetrically arranged lifting cylinders 12. Each conveying mechanism is equipped with two lifting cylinders 12, located at the front and rear ends of the conveying mechanism respectively, to ensure the smoothness of the lifting movement. Lifting brackets 13 are fixedly connected to the ends of the two lifting cylinders 12 that are close to each other. The lifting brackets 13 connect the two lifting cylinders 12 into a whole, forming a stable lifting platform. Rollers 14, 15, and 16 are rotatably connected between the two lifting brackets 13. These three rollers are arranged in a triangle between the lifting brackets 13, providing support and guidance for the operation of the conveyor belt 22. A telescopic fixing bracket 17 is fixedly connected between the two lifting brackets 13 near roller 16. The telescopic fixing bracket 17 serves as... The fixed base of the telescopic mechanism ensures the stability of the telescopic movement. Two telescopic hydraulic cylinders 18 are fixedly connected to the telescopic fixed bracket 17. The two telescopic hydraulic cylinders 18 are arranged side by side to provide sufficient telescopic power. The telescopic support 19 is fixedly connected to the end of the telescopic hydraulic cylinder 18 away from the roller 3 16. The telescopic support 19 serves as a movable support structure to realize the telescopic adjustment of the end of the conveyor belt 22. The telescopic roller 1 20 and the telescopic roller 21 are rotatably connected to the telescopic support 19. These two telescopic rollers provide support for the operation of the conveyor belt 22 at the telescopic end. The outer ends of roller 1 14, roller 2 15, roller 3 16, telescopic roller 1 20 and telescopic roller 2 21 are provided with the same conveyor belt 22. The conveyor belt 22 is wrapped around all the rollers to form a complete conveying circuit.
[0049] Furthermore, a baffle 23 is fixedly connected to the top of the telescopic support 19. The baffle 23 is located at the highest position of the telescopic support 19 and plays a role in protecting the conveyor belt 22 when the cutting mechanism 3 is working. The axes of roller 14 and roller 25 are located on the same horizontal plane. This arrangement ensures that the conveyor belt 22 runs smoothly between the two rollers. The axes of roller 316 and telescopic roller 20 are located on the same horizontal plane, ensuring the height consistency of the conveyor belt 22 between the fixed end and the telescopic end.
[0050] The second telescopic roller 21 is located between the first roller 14 and the first telescopic roller 20, providing intermediate support for the conveyor belt 22 and preventing the conveyor belt 22 from sagging over a long span. The cylinder body of the telescopic hydraulic cylinder 18 is fixedly connected to the telescopic fixed bracket 17, and the piston rod of the telescopic hydraulic cylinder 18 is fixedly connected to the telescopic bracket 19. This connection method ensures that the telescopic hydraulic cylinder 18 can effectively drive the telescopic bracket 19 to reciprocate.
[0051] The cylinder body of the lifting cylinder 12 is fixedly connected to the base, and the piston rod of the lifting cylinder 12 is fixedly connected to the lifting bracket 13. Through this connection, the lifting cylinder 12 can drive the entire conveying mechanism to move up and down. A motor is fixedly connected to the lifting bracket 13 at the corresponding position of the second roller 15. The motor provides rotational power to the second roller 15, thereby driving the conveyor belt 22 to run.
[0052] A clearance groove is provided on the lifting support 13 at the position corresponding to the telescopic support 19. The clearance groove is designed to prevent the telescopic support 19 from interfering with the lifting support 13 during the telescopic movement. The cutting cylinder 4, the lifting cylinder 12 and the telescopic hydraulic cylinder 18 are all double-acting cylinders and are all electrically connected to the external control system. The external control system can accurately control the action sequence and stroke of each cylinder to realize the automated operation of the equipment. A tray is fixedly connected between the rear conveying mechanism 1 and the front conveying mechanism 2. The tray is located below the two conveying mechanisms and is used to collect the cut bait pieces.
[0053] The working process of the bait stacking machine is as follows: When in use, the bait strip to be cut is placed at the top of the front conveyor 2. The bait strip spans between the rear conveyor 1 and the front conveyor 2. After the motor starts, it drives the second roller 15 to rotate. The second roller 15 then drives the conveyor belt 22 to rotate. The conveyor belt 22 transports the bait strip to the bottom position of the cutting mechanism 3. When the bait strip reaches the cutting position, the cutting cylinder 4 starts, driving the bracket 5, drive ring 6, vibration plate 7, cutting ring 8, molding plate 9, return spring 10 and negative pressure pipe 11 to move downward together to cut the bait strip. During the cutting process, the cutting ring 8 first contacts the top of the bait strip. As the cutting cylinder 4 continues to press down, the cutting ring 8 gradually cuts into the inside of the bait strip, completing the cutting of the bait strip.
[0054] After cutting, the cutting cylinder 4 reverses its movement, causing the cutting mechanism 3 to move upward and detach from the bait strip. At this time, the telescopic hydraulic cylinder 18 is activated, pushing the telescopic bracket 19, telescopic roller 1 20, telescopic roller 21 and conveyor belt 22 to move synchronously, so that the conveyor belts 22 on the rear conveyor mechanism 1 and the front conveyor mechanism 2 move closer to each other, allowing the bait strip to transition from the front conveyor mechanism 2 to the rear conveyor mechanism 1. After the transition is completed, the telescopic hydraulic cylinder 18 reverses its movement, causing the conveyor belts 22 on the rear conveyor mechanism 1 and the front conveyor mechanism 2 to move away from each other. During this process, the bait pieces cut by the cutting mechanism 3 fall onto the tray under the action of gravity.
[0055] In order to achieve the stacking function of bait pieces, whenever a cut bait piece is added to the tray, the lifting cylinder 12 is activated, which drives the corresponding rear conveyor mechanism 1 and front conveyor mechanism 2 to move upward by the thickness of one bait piece, leaving space for the next bait piece to fall. This process is repeated continuously to achieve continuous cutting and orderly stacking of bait pieces.
[0056] The dual conveyor design ensures stable conveying and precise positioning of the bait strips, guaranteeing accurate cutting position. Secondly, the cutting mechanism 3 uses a cylinder drive, allowing for controllable cutting force and stable cutting speed, suitable for cutting bait strips of various hardnesses. Thirdly, the telescopic mechanism allows the conveyor belt 22 to approach and separate as needed, achieving a smooth transition between different conveyor mechanisms. Furthermore, the lifting mechanism can be precisely adjusted according to the thickness of the bait pieces, ensuring neatness and consistency of the stacked pieces. Finally, the baffle 23 effectively protects the conveyor belt 22 from damage during cutting, extending the equipment's service life. The entire equipment is compact, easy to operate, and highly automated, significantly improving the efficiency and quality of bait processing.
[0057] Example 2:
[0058] like Figures 1 to 11 As shown, this embodiment is a further improvement on the first embodiment, providing a bait stacking machine with high-precision vibration cutting and pattern pressing functions. This bait stacking machine can not only realize the automatic feeding, precise cutting and orderly stacking of bait strips, but also greatly improve the cutting efficiency through piezoelectric vibration technology, and imprint exquisite patterns on the surface of the bait, meeting the needs of high-end bait processing.
[0059] The bait stacking machine includes a base, which provides a stable support foundation for the entire equipment. A rear conveying mechanism 1 and a front conveying mechanism 2 are fixedly connected to the base, arranged symmetrically on the left and right. This symmetrical layout design ensures the structural balance and operational stability of the equipment. A cutting mechanism 3 is provided on the upper side of the front conveying mechanism 2. The cutting mechanism 3 is located directly above the front conveying mechanism 2, which facilitates high-precision cutting of the bait strips conveyed by the front conveying mechanism 2. The bait strips to be cut are placed at the top of the rear conveying mechanism 1 and the front conveying mechanism 2. The bait strips span between the two conveying mechanisms, preparing for subsequent high-precision cutting, molding and stacking operations.
[0060] The cutting mechanism 3 includes a cutting cylinder 4 fixedly connected to the base. The cutting cylinder 4 provides the power source for the cutting mechanism 3 to reciprocate up and down. A bracket 5 is fixedly connected to the bottom end of the cutting cylinder 4. The bracket 5 serves as the carrier of the cutting components, ensuring the stable connection and precise positioning of each cutting component. A drive ring 6 is fixedly connected to the bottom end of the bracket 5. The drive ring 6 is composed of multiple vibrating strips. These vibrating strips are arranged in a ring around the bottom end of the bracket 5, providing a basis for the generation and transmission of high-frequency vibration. In this embodiment, the vibrating strips are piezoelectric stacks made of piezoelectric material. The strain direction of the piezoelectric stacks is the tangential direction of the drive ring 6. One end of the vibrating strip is fixedly connected to the bracket 5. The piezoelectric stack is a new type of vibration element. When a voltage is applied, it can generate precise and controllable mechanical deformation, thereby generating high-frequency vibration. By setting the strain direction of multiple piezoelectric stacks to the tangential direction of the drive ring 6, a ring-shaped high-frequency vibration field can be generated in the drive ring 6. This vibration can be effectively transmitted to the subsequent cutting components.
[0061] Multiple vibrating strips are fixedly connected to the same vibrating plate 7 at one end away from the support 5. The vibrating plate 7 collects and transmits the high-frequency vibrations generated by each piezoelectric stack, forming a synchronous vibration output. The vibrating plate 7 is made of high-strength material and has good vibration transmission characteristics and structural stability, ensuring that the vibration signal can be completely transmitted to the cutting ring 8. The bottom end of the vibrating plate 7 is threaded to the cutting ring 8. Through the threaded connection, the cutting ring 8 can be firmly fixed on the vibrating plate 7, and it is easy to disassemble and replace. After receiving the high-frequency vibration transmitted by the vibrating plate 7, the cutting ring 8 will also generate corresponding high-frequency vibration, which greatly improves the cutting efficiency.
[0062] A molding plate 9 is slidably connected inside the cutting ring 8. The molding plate 9 can slide freely in the axial direction inside the cutting ring 8 to achieve the precise molding function of the bait. A connecting rod is fixedly connected to the top of the molding plate 9. The connecting rod passes through the vibrating plate 7 upward, and a limit block is fixedly connected to the top of the connecting rod. This connecting rod structure design allows the position of the molding plate 9 to be precisely controlled. The limit block ensures that the molding plate 9 will not exceed the preset range when it moves upward. At the same time, the setting of the connecting rod also provides a stable guiding effect for the molding plate 9. A return spring 10 is fixedly connected between the vibrating plate 7 and the molding plate 9. The return spring 10 provides a downward restoring force for the molding plate 9, ensuring that the molding plate 9 can automatically return to its original position after completing the molding action.
[0063] Multiple micro-holes are formed along the axial direction of the molding plate 9. These micro-holes penetrate the entire thickness of the molding plate 9, providing a channel for the negative pressure system. A mold is snapped into the bottom of the molding plate 9. The mold is designed with various exquisite patterns, which can imprint corresponding decorative patterns on the surface of the bait. The mold is connected by a detachable snap-fit method, which makes it easy to replace the mold with different patterns as needed. A negative pressure pipe 11 is fixedly connected to the top of the vibration plate 7. The negative pressure pipe 11 is connected to the external negative pressure system through a pipe, providing negative pressure power for the adsorption and fixation of the molding plate 9.
[0064] Furthermore, the bottom of the cutting ring 8 has a wedge-shaped structure. This wedge design makes it easier for the cutting ring 8 to cut into the bait strips during the cutting process, reducing cutting resistance and improving cutting accuracy. Both the cutting ring 8 and the mold are coated with a hydrophobic coating. The hydrophobic coating can effectively prevent the bait material from sticking to the cutting ring 8 and the mold, keep the cutting and molding surfaces clean, extend the service life of the equipment, and ensure the consistency of cutting and molding effects.
[0065] Both the rear conveying mechanism 1 and the front conveying mechanism 2 include symmetrically arranged lifting cylinders 12. Each conveying mechanism is equipped with two lifting cylinders 12, located at the front and rear ends of the conveying mechanism respectively, to ensure the smoothness of the lifting movement. The ends of the two lifting cylinders 12 that are close to each other are fixedly connected to lifting brackets 13. The lifting brackets 13 connect the two lifting cylinders 12 into a whole to form a stable lifting platform. The lifting brackets 13 have a triangular structure. This triangular design has excellent structural stability and rigidity, can withstand large loads, and is relatively lightweight, which is conducive to the precise control of the lifting movement.
[0066] Rollers 14, 15, and 16 are rotatably connected between the two lifting supports 13. These three rollers are arranged in a triangle between the lifting supports 13 to provide support and guidance for the operation of the conveyor belt 22. The axes of rollers 15 and 16 are located in the same vertical plane. This arrangement ensures that the tension of the conveyor belt 22 remains consistent in the vertical direction, thus ensuring the stability of the conveyor belt 22. A telescopic fixed support 17 is fixedly connected between the two lifting supports 13 near roller 16. The telescopic fixed support 17 serves as the fixed base for the telescopic mechanism, ensuring the stability of the telescopic movement. Two telescopic hydraulic cylinders 18 are fixedly connected to the telescopic fixed support 17. The two telescopic hydraulic cylinders 18 are arranged side by side to provide sufficient telescopic power. A telescopic support 19 is fixedly connected to the end of the telescopic hydraulic cylinder 18 away from roller 16. The telescopic support 19 serves as a movable support structure to realize the telescopic adjustment of the end of the conveyor belt 22.
[0067] Telescopic roller 1 20 and telescopic roller 21 are rotatably connected to the telescopic support 19. These two telescopic rollers provide support for the operation of the conveyor belt 22 at the telescopic end. The outer ends of roller 1 14, roller 2 15, roller 3 16, telescopic roller 1 20 and telescopic roller 21 are provided with the same conveyor belt 22. The conveyor belt 22 is wrapped around all the rollers to form a complete conveying loop. A baffle 23 is fixedly connected to the top of the telescopic support 19. The baffle 23 is located at the highest position of the telescopic support 19. When the cutting mechanism 3 is working, it plays a role in protecting the conveyor belt 22 and preventing the high-frequency vibrating cutting ring 8 from accidentally contacting the conveyor belt 22 and causing damage.
[0068] The axes of roller 14 and roller 25 are located on the same horizontal plane. This arrangement ensures the smooth operation of the conveyor belt 22 between the two rollers. The axes of roller 316 and telescopic roller 120 are located on the same horizontal plane, ensuring the height consistency of the conveyor belt 22 between the fixed end and the telescopic end. Telescopic roller 21 is located between roller 14 and telescopic roller 120, providing intermediate support for the conveyor belt 22 and preventing the conveyor belt 22 from sagging over a long span.
[0069] The cylinder body of the telescopic hydraulic cylinder 18 is fixedly connected to the telescopic fixed bracket 17, and the piston rod of the telescopic hydraulic cylinder 18 is fixedly connected to the telescopic bracket 19. This connection method ensures that the telescopic hydraulic cylinder 18 can effectively drive the telescopic bracket 19 to reciprocate. The cylinder body of the lifting cylinder 12 is fixedly connected to the base, and the piston rod of the lifting cylinder 12 is fixedly connected to the lifting bracket 13. Through this connection method, the lifting cylinder 12 can drive the entire conveying mechanism to move up and down. A motor is fixedly connected to the lifting bracket 13 at the corresponding position of the second roller 15. The motor power shaft is fixedly connected to the second roller 15. The motor provides precise rotational power to the second roller 15, thereby driving the conveyor belt 22 to run.
[0070] A clearance groove is provided on the lifting support 13 at the position corresponding to the telescopic support 19. The clearance groove is designed to avoid interference between the telescopic support 19 and the lifting support 13 during the telescopic movement. The cutting cylinder 4, the lifting cylinder 12 and the telescopic hydraulic cylinder 18 are all double-acting cylinders and are all electrically connected to the external control system. The external control system can accurately control the action sequence and stroke of each cylinder, and can also control the vibration frequency and amplitude of the piezoelectric stack to achieve a high degree of automated operation of the equipment. A tray is fixedly connected between the rear conveying mechanism 1 and the front conveying mechanism 2. The tray is located below the two conveying mechanisms and is used to collect the cut and molded bait pieces.
[0071] The working process of the bait stacking machine is as follows: When in use, the bait strip to be cut is placed at the top of the front conveyor 2. The bait strip spans between the rear conveyor 1 and the front conveyor 2. After the motor is started, the second roller 15 is driven to rotate through the power shaft. The second roller 15 then drives the conveyor belt 22 to rotate. The conveyor belt 22 transports the bait strip to the bottom position of the cutting mechanism 3. When the bait strip reaches the cutting position, the external control system first starts the piezoelectric stack, so that the vibrating strip starts to generate high-frequency vibration. The vibration is transmitted to the vibrating plate 7 through the drive ring 6, and then to the cutting ring 8, so that the cutting ring 8 generates high-frequency vibration.
[0072] Subsequently, the cutting cylinder 4 is activated, driving the bracket 5, drive ring 6, vibrating plate 7, cutting ring 8, molding plate 9, return spring 10, and negative pressure pipe 11 to move downwards together, performing high-frequency vibration cutting on the bait strip. During the cutting process, the cutting ring 8, which is in a high-frequency vibration state, first contacts the top of the bait strip. The high-frequency vibration can significantly reduce the cutting resistance, allowing the cutting ring 8 to cut into the inside of the bait strip more easily. At the same time, the molding plate 9 also contacts the top of the bait strip. As the cutting ring 8 continues to press down, the molding plate 9 moves upwards under the pressure of the bait. At this time, the external negative pressure system generates negative pressure between the vibrating plate 7 and the molding plate 9 through the negative pressure pipe 11.
[0073] The negative pressure is used to expel the gas between the mold and the bait block through multiple micro-holes on the molding plate 9, so that the molding plate 9 can tightly fit and fix the cut bait block. During this process, the molding plate 9 compresses the return spring 10 until the cutting ring 8 completes the complete cutting of the bait block strip. After the cutting is completed, the negative pressure is released, and the molding plate 9 moves downward under the elastic force of the return spring 10, which drives the mold to squeeze the bait block, so that the cut bait block is imprinted with the exquisite pattern designed on the mold. Then, the cutting ring 8 is moved upward, and the molding plate 9 pushes the cut and imprinted bait block out of the cutting ring 8 under the action of the return spring 10.
[0074] After cutting and molding, the cutting cylinder 4 reverses its movement, causing the cutting mechanism 3 to move upward and detach from the bait strip. At this time, the telescopic hydraulic cylinder 18 is activated, pushing the telescopic bracket 19, telescopic roller 1 20, telescopic roller 21 and conveyor belt 22 to move synchronously, so that the conveyor belts 22 on the rear conveyor mechanism 1 and the front conveyor mechanism 2 move closer to each other, allowing the bait strip to transition from the front conveyor mechanism 2 to the rear conveyor mechanism 1. After the transition is completed, the telescopic hydraulic cylinder 18 reverses its movement, causing the conveyor belts 22 on the rear conveyor mechanism 1 and the front conveyor mechanism 2 to move away from each other. During this process, the cut and imprinted bait pieces fall onto the tray under the action of gravity.
[0075] To achieve the stacking function of bait pieces, whenever a cut and imprinted bait piece is added to the tray, the lifting cylinder 12 is activated, which drives the corresponding rear conveyor mechanism 1 and front conveyor mechanism 2 to move upward by the thickness of one bait piece, reserving space for the next bait piece to fall. This process is repeated continuously to achieve continuous high-precision cutting, pattern molding, and orderly stacking of bait pieces.
[0076] When in use, place the bait strips to be cut at the top of the front conveyor 2. Then, the motor drives the roller 15 to rotate, which in turn drives the conveyor belt 22 to rotate. The conveyor belt 22 transports the bait strips to the bottom of the cutting mechanism 3. The cutting mechanism 3 then cuts the bait strips. After cutting, the rear conveyor 1 and the front conveyor 2 are brought closer together so that the bait strips can be transferred from the front conveyor 2 to the rear conveyor 1. Then, the conveyor belts 22 on the rear conveyor 1 and the front conveyor 2 are moved away from each other. During this process, the bait pieces cut by the cutting mechanism 3 fall onto the tray under the action of gravity. This process is repeated until the bait pieces are cut and stacked.
[0077] When it is necessary to bring the conveyor belts 22 closer to each other, the telescopic hydraulic cylinder 18 pushes the telescopic bracket 19, the first telescopic roller 20, the second telescopic roller 21 and the conveyor belt 22 to move synchronously, thereby making the conveyor belts 22 move closer to each other or further away.
[0078] When the cutting mechanism 3 needs to cut the bait strip, the cutting cylinder 4 drives the bracket 5, drive ring 6, vibrating plate 7, cutting ring 8, molding plate 9, return spring 10, and negative pressure pipe 11 to move downwards together to cut the bait strip. During this process, the cutting ring 8 and molding plate 9 simultaneously contact the top of the bait strip. Then, the cutting ring 8 continues to press down, and the molding plate 9 moves upwards under the pressure of the bait. At the same time, the external negative pressure system generates negative pressure between the vibrating plate 7 and the molding plate 9 through the negative pressure pipe 11. The negative pressure is discharged through the micropores on the molding plate 9, allowing the molding plate 9 to fix the cut bait. During this process, the molding plate 9 compresses the return spring 10 until the cutting ring 8 completes the cutting of the bait strip. Then, the negative pressure molding plate 9 is removed and moves downward under the elastic force of the return spring 10, driving the mold to squeeze the bait block, so that the desired pattern is imprinted on the cut bait block. Then, the cutting ring 8 is moved upward and the molding plate 9 is lowered under the action of the return spring 10. The cut and imprinted bait block is pushed out from the cutting ring 8. Then, the cut and imprinted bait block continues to move with the conveyor belt until it reaches the top of the tray. Then, the conveyor belts 22 on the rear conveyor mechanism 1 and the front conveyor mechanism 2 move away from each other. At this time, the cut bait block falls onto the tray under the action of gravity. This process is repeated continuously. After each cut bait block is added to the tray, the lifting cylinder 12 drives the corresponding rear conveyor mechanism 1 and front conveyor 2 to move upward by the thickness of one bait block. This process is repeated continuously.
[0079] During the cutting process, the drive ring 6 generates high-frequency vibration, which is transmitted to the cutting ring 8 through the vibrating plate 7, causing the cutting ring 8 to vibrate at high frequency. This allows the cutting ring 8 to cut the bait better and effectively prevents the bait from sticking to the cutting ring 8. The baffle 23 is used to block the conveyor belt 22 during cutting to prevent the conveyor belt 22 from being pressed down and deformed.
[0080] The application of piezoelectric stacking vibration strips enables the cutting ring 8 to generate high-frequency vibration, significantly improving cutting efficiency while effectively preventing the bait from sticking to the cutting ring 8, ensuring the stability of cutting quality. Secondly, through the combined use of the molding plate 9 and the mold, exquisite patterns can be imprinted on the surface of the bait, greatly enhancing the added value and aesthetics of the product. Thirdly, the design of the connecting rod and limit block ensures the precision of the position control of the molding plate 9, guaranteeing the consistency and accuracy of the molded pattern. In addition, the wedge-shaped cutting ring 8 design further reduces cutting resistance and improves cutting accuracy. The application of hydrophobic coating effectively prevents adhesion problems, extends the service life of the equipment, and reduces maintenance costs. The triangular lifting bracket 13 provides better structural stability and load-bearing capacity. The direct connection between the motor power shaft and the roller 15 ensures the precision and reliability of the transmission. The introduction of the negative pressure system makes the molding process more stable and controllable, ensuring the clarity and consistency of the pattern imprint. The entire equipment not only has basic cutting and stacking functions but also adds high-precision vibration cutting and pattern molding functions, which can meet the diverse needs of the high-end bait processing market and significantly enhance the market competitiveness of the product.
