Description

Technical Field

[0001] The present invention relates to the technical field of agricultural mechanization equipment, and particularly to an automatic silkworm cocoon separation device and method. Background Art

[0002] In the process of silk production, separating the silkworm pupae inside the silkworm cocoons from the cocoon shells is a key process. At present, this process mainly relies on manual labor. Operators cut the silkworm cocoons by hand or using simple tools, and then take out the internal silkworm pupae. This traditional manual separation method has significant technical defects: First, the production efficiency is low, the labor intensity is high, and it is difficult to meet the requirements of large-scale production; Second, the separation quality is unstable. Due to subjective factors such as the proficiency and fatigue of the operators, it is difficult to keep the cutting depth and position consistent, which easily causes damage to the cocoon shells or breaks the silk threads, thus affecting the subsequent silk reeling process and reducing the quality of the final silk products.

[0003] To overcome the above deficiencies of manual operation, some automated silkworm cocoon separation devices have emerged in the industry. However, the existing automated devices still have several technical problems in actual applications.

[0004] First, the adaptability to silkworm cocoons is poor. As a natural product, silkworm cocoons have significant individual differences in physical characteristics such as size, shape, thickness, etc. Many existing devices are designed for specific specifications of silkworm cocoons, and their clamping and cutting mechanisms lack sufficient flexibility and adaptive adjustment capabilities. When processing mixed batches of silkworm cocoons with different sizes, problems such as unstable clamping, cutting failure, or damage to the silkworm cocoons are likely to occur, resulting in limited overall automation level and processing success rate of the device.

[0005] Second, the processing process is not gentle enough to ensure the integrity of the cocoon shells. Although the outer shell of the silkworm cocoon has a certain toughness, the internal silk layer structure is delicate and easy to damage. Existing devices often have difficulty in precisely controlling the acting force during the clamping and cutting processes. Excessive clamping force or cutting force will damage the integrity of the cocoon shells and affect their value as high-quality raw materials.

[0006] Therefore, there is an urgent need in the current technical field for a new type of automatic silkworm cocoon separation solution to solve the technical problems existing in the prior art, such as low automation level, poor adaptability to different specifications of silkworm cocoons, and easy damage to silkworm cocoons during the processing process, so as to achieve the high efficiency, automation, and standardization of the silkworm cocoon separation process while ensuring the integrity of the cocoon shells. Summary of the Invention

[0007] In view of this, the object of the present invention is to provide an automatic cocoon separation device and method, which can realize the mechanization of the cocoon cutting process, liberate the manual labor in the recycling process, reduce the operation links, lower the labor cost, and improve the production efficiency on the basis of completing cocoon cutting and separating pupae from cocoons.

[0008] To solve the above technical problems, the technical solution of the present invention is: an automatic cocoon separation device, including a frame, a support plate is fixedly connected to the frame, a waist-shaped track is arranged on the support plate, a plurality of transfer plates are arranged on the waist-shaped track, a rotating wheel is rotatably connected to the support plate, a driving chain is connected to the rotating wheel, the driving chain drives the transfer plates to move, an elastic clamping mechanism is arranged on the transfer plates, a feeding component and a discharging component are arranged on the frame, both the feeding component and the discharging component are located on the waist-shaped track and are used to correspond to the elastic clamping mechanism, the rotating wheel is driven by a power system, and a cutting mechanism is connected to the frame, and the cutting mechanism is located between the feeding component and the discharging component; When the elastic clamping mechanism corresponds to the feeding component, the elastic clamping mechanism clamps the cocoon, and when the elastic clamping mechanism corresponds to the discharging component, the elastic clamping mechanism releases the cocoon.

[0009] To implement the above technical solution, the power system drives the rotating wheel to rotate, and the rotating wheel drives a plurality of transfer plates to perform continuous circular motion along the waist-shaped track through the driving chain. When the elastic clamping mechanism on a certain transfer plate moves to the position of the feeding component, it will be triggered and automatically clamp a cocoon; then, the transfer plate carries the cocoon and continues to move along the track. When passing through the cutting mechanism, the cocoon is cut; finally, when the transfer plate moves to the position of the discharging component, the elastic clamping mechanism is triggered to release, and the processed cocoon is unloaded. Integrating the processes of feeding, clamping, transferring, cutting, and discharging cocoons on a continuous circular production line realizes the full automation of the entire separation process without manual intervention. Utilizing the coordinated work of the waist-shaped track and a plurality of transfer plates allows multiple workstations to operate simultaneously, greatly improving the processing efficiency and processing capacity of cocoons.

[0010] As a preferred solution of the present invention, the elastic clamping mechanism includes a cross beam, a sliding rod, a fixed block, an elastic member, a first clamping plate, and a second clamping plate. The cross beam is fixed to the transfer plate, the sliding rod is fixed to the cross beam, the length direction of the sliding rod is parallel to the length direction of the cross beam, a plurality of fixed blocks are fixed to the cross beam, the first clamping plate and the second clamping plate are both slidably connected to the sliding rod and are both located between adjacent two fixed blocks, one end of an elastic member is respectively connected to the fixed block and the first clamping plate, and the other end of the elastic member is respectively connected to the fixed block and the second clamping plate. A clamping area for clamping the cocoon is formed between the first clamping plate and the second clamping plate.

[0011] To implement the above technical solution, in the natural state, two elastic members respectively exert an elastic force towards each other on the first clamping plate and the second clamping plate, causing the two clamping plates to be pushed towards each other, so that the clamping area between them is in the default clamping state. When moving to the loading or unloading station with the conveyor plate, an external component will exert a reverse force on the two first clamping plates and the second clamping plate, forcing the first clamping plate and the second clamping plate to overcome the elastic force and separate from each other, and the clamping area is opened. At this time, the cocoon can be placed. When the external force disappears, the elastic force of the elastic member will immediately drive the two clamping plates to return to the clamping state, thus fixing the cocoon. First, the automation of clamping and the self-adaptability of the force are realized. Using the pre-tightening force provided by the elastic member, the mechanism can automatically and reliably clamp the cocoon, and can adapt to size changes within a certain range, ensuring the stability of clamping and the universality for different cocoons. Second, the control and structure are simplified. The power of the clamping action comes from the passive elastic member, rather than an independent motor or cylinder. Only a simple external mechanism needs to be set at the fixed loading and unloading stations to open it, which greatly simplifies the structural complexity and control requirements of the clamping mechanism on each conveyor plate, and improves the reliability and economy of the whole system.

[0012] As a preferred solution of the present invention, a first clamping groove is formed on the first clamping plate, a second clamping groove is formed on the second clamping plate, and the first clamping groove and the second clamping groove are arranged opposite to each other.

[0013] To implement the above technical solution, the design of the first clamping groove and the second clamping groove can have a larger area of contact with the surface of the oval cocoon, greatly enhancing the stability of clamping, and effectively preventing the cocoon from sliding, deflecting or falling during transportation and cutting. At the same time, the arc-shaped contours of the first clamping groove and the second clamping groove play a role in automatic centering and positioning, ensuring that the position and posture of each cocoon being clamped are highly consistent, providing a key guarantee for the accuracy of the subsequent cutting process.

[0014] As a preferred solution of the present invention, a limiting plate located between the first clamping plate and the second clamping plate is fixedly connected to the cross beam. A first limiting groove is formed on the first clamping plate, a second limiting groove is formed on the second clamping plate, and two ends of the limiting plate are respectively used to abut against the bottom walls of the first limiting groove and the second limiting groove.

[0015] To implement this technical solution, when the elastic member drives the first and second clamping plates to slide inward to clamp the cocoons, the ends of the limit plates come into contact with the bottom walls of the first and second limit grooves, precisely defining the minimum clamping distance of the clamps. This design ensures that the elastic member provides a flexible clamping force while also preventing damage to the cocoons caused by over-tightening, ensuring stable clamping of cocoons of varying sizes. This dual guarantee significantly improves clamping reliability and the consistency of cutting positions, further enhancing the operating precision and adaptability of the entire automatic cocoon separation device.

[0016] As a preferred solution of the present invention, the loading assembly includes a first connecting wheel, a second connecting wheel, a third connecting wheel and a loading plate, the first connecting wheel is rotatably connected to the side of the first clamping plate facing the track, the second connecting wheel is rotatably connected to the side of the second clamping plate facing the track, the loading plate is fixed on the frame, and multiple third connecting wheels are connected to the loading plate and arranged in parallel, and the outer cylindrical surface of the first connecting wheel and the outer cylindrical surface of the second connecting wheel are both used to interfere with the outer cylindrical surface of the third connecting wheel.

[0017] To implement the above technical solution, when the conveyor plate moves to the loading position, the first connecting wheel and the second connecting wheel on the first clamping plate and the second clamping plate will respectively contact the third connecting wheel on the loading plate. As the conveyor plate continues to move, the third connecting wheel applies an extrusion force to the first and second connecting wheels, and this force is transmitted to the first and second clamping plates, forcing the first and second clamping plates to slide outward, thereby opening the clamping area to receive the cocoons. When the first and second clamping plates move beyond the range of the third connecting wheel, the extrusion force disappears, and the elastic member immediately drives the first and second clamping plates to reset and automatically clamp the cocoons. The movement of the conveyor plate is converted into the opening and closing action of the first and second clamping plates, which realizes gentle, precise and efficient automatic loading, avoids damage to the first and second clamping plates and the cocoons caused by hard impact, and further improves the automation level and reliability of the equipment.

[0018] As a preferred solution of the present invention, the blanking assembly includes a blanking plate, an expansion plate and a transmission mechanism, the blanking plate is fixed on the frame, the expansion plate is fixed on the blanking plate, the end of the expansion plate is provided with a first inclined surface and a second inclined surface, the outer cylindrical surface of the first connecting wheel is used to contact the first inclined surface, the outer cylindrical surface of the second connecting wheel is used to contact the second inclined surface, and the transmission mechanism is located below the expansion plate and is used to receive the cocoons.

[0019] To implement the above technical solution, when the transfer plate moves to the discharging position, the first connecting wheel on the first clamping plate and the second connecting wheel on the second clamping plate will respectively contact the first inclined surface and the second inclined surface on the expanding plate. As the transfer plate continues to move, the inclined surfaces will exert an outward thrust on the connecting wheels, and this thrust is transmitted to the first clamping plate and the second clamping plate through the connecting wheels, forcing them to expand to both sides, thereby opening the clamping area. The released cocoons then fall into the transmission mechanism below. This design utilizes the inclined surface structure to convert the kinetic energy of horizontal movement into the expanding force in the vertical direction, achieving gentle and reliable automatic discharging. It avoids the damage to cocoons caused by sudden release, ensures the integrity and efficiency of the separation process, and further improves the automation level of the entire device.

[0020] As a preferred embodiment of the present invention, the cutting mechanism includes a fixing plate, a cutting motor, and a cutting tool. The fixing plate is fixedly connected to the frame, and the cutting motor is fixed on the fixing plate and drives the cutting tool to rotate to cut the cocoons.

[0021] To implement the above technical solution, the cutting mechanism is firmly installed on the frame through the fixing plate and is positioned between the feeding assembly and the discharging assembly. When the elastic clamping mechanism holding the cocoons moves to the lower part of the cutting mechanism along with the transfer plate, the cutting motor will drive the cutting tool to rotate at a high speed. The rotating cutting tool precisely cuts the outer shell of the cocoons, thereby opening the cocoon shell to prepare for subsequent removal of the silkworm pupae. This design fully automates the cutting process, avoids the inconsistency and low efficiency of manual cutting, improves the accuracy and repeatability of cutting. Through the stable and controllable rotation of the cutting tool for cutting, it can effectively reduce the damage to the cocoon filaments, thus ensuring the quality of the subsequent silk reeling process and the quality of the final silk products.

[0022] As a preferred embodiment of the present invention, the transmission mechanism includes a discharging rack, a discharging motor, a conveyor belt, and conveying rollers. The conveying rollers are rotatably connected to the discharging rack, the conveyor belt is tensioned by a plurality of conveying rollers, the discharging motor is connected to the discharging rack and drives the conveying rollers to rotate, and a plurality of connecting plates are fixedly connected to the conveyor belt, and the plurality of connecting plates are arranged along the length direction of the conveyor belt.

[0023] To implement the above technical solution, when the cut and separated cocoons fall from the discharging assembly, they will be directly received by the conveyor belt. The plurality of connecting plates fixedly connected to the conveyor belt can effectively support the cocoons and convey them forward as the conveyor belt moves. This design realizes the automatic collection and transfer of the separated cocoons, avoids manual secondary processing, and greatly improves the overall automation level and continuity of the production line. At the same time, through the smooth conveying of the conveyor belt, it can reduce the possible secondary damage to the cocoons during the handling process after separation, ensure the integrity of the cocoon shell, and thus improve the overall production efficiency and product quality.

[0024] As a preferred embodiment of the present invention, a calibration plate is fixedly connected to the side wall of the transfer plate. A calibration groove is formed in the calibration plate. A cylinder is hinged to the frame. The telescopic shaft of the cylinder is hinged to an adjusting rod. The end of the adjusting rod away from the telescopic shaft is fixedly connected to a connecting shaft. The connecting shaft is rotatably connected to the frame. A roller is connected to the connecting shaft. The roller is used to be embedded in the calibration groove. The roller is located on the side of the feeding assembly away from the cutting mechanism.

[0025] To achieve the above technical solution, when the transfer plate moves near the feeding assembly, the cylinder on the frame extends its telescopic shaft, driving the roller on the connecting shaft to be embedded in the calibration groove on the side wall of the transfer plate. The embedding fit between the roller and the calibration groove can accurately lock the position of the transfer plate, making it stationary or in a predetermined precise position when the feeding operation is required. This calibration and positioning mechanism overcomes the problem of inaccurate positioning caused by mechanical transmission errors or inertia, ensuring that the elastic clamping mechanism can be accurately aligned with the feeding assembly, thus greatly improving the success rate and stability of feeding, and also providing a reliable positioning basis for the subsequent cutting process.

[0026] To solve the above technical problems, the present invention also discloses a method for automatic separation of silkworm cocoons, including a device for automatic separation of silkworm cocoons as described in any one of claims 1-9, characterized by the following steps: S1. Using the elastic clamping mechanism to adaptively clamp and position a single silkworm cocoon; S2. Driving the elastic clamping mechanism to move along a preset waist-shaped track through the power system, so that the clamped silkworm cocoon passes through the cutting mechanism, and a notch is cut on the silkworm cocoon shell by the cutting mechanism; S3. Continuing to drive the elastic clamping mechanism to move, making it run to a horizontally inverted state along the waist-shaped track, and using the gravity effect to make the silkworm pupa in the silkworm cocoon slide out of the cocoon shell through the notch and fall; S4. After the silkworm pupa falls, controlling the elastic clamping mechanism to release the clamping force, so that the cut empty cocoon shell falls due to the gravity effect, thus completing the automatic separation and classification of the silkworm pupa and the cocoon shell.

The discharging motor 30 is fixedly connected to the discharging rack 29 and drives the conveying roller 32 to rotate. Through the action of friction, the conveying roller 32 drives the conveyor belt 31 to rotate. A plurality of connecting plates 39 are fixedly connected to the surface of the conveyor belt 31, and the plurality of connecting plates 39 are arranged along the length direction of the conveyor belt 31. The connecting plates 39 are horizontally arranged.

[0043] A cutting mechanism 33 is connected to the frame 1, and the cutting mechanism 33 is located between the feeding component 20 and the discharging component 25.

[0044] The cutting mechanism 33 includes a fixed plate 34, a cutting motor 35, and a cutting tool 36. The fixed plate 34 is fixedly connected to the frame 1 and is horizontally arranged. The fixed plate 34 is located above the first clamping plate 12 and the second clamping plate 13. The cutting motor 35 is fixed on the fixed plate 34 and drives the cutting tool 36 to rotate to cut the cocoons. The cutting tool 36 is close to the upper surfaces of the first clamping plate 12 and the second clamping plate 13 for cutting the cocoons.

[0045] A calibration plate 40 is fixedly connected to the side wall of each conveying plate 4. The calibration plate 40 is located on the side of the conveying plate 4 facing away from the support plate 2. A calibration groove 41 is formed in the calibration plate 40. Two guiding inclined surfaces 42 are formed on the side wall of the calibration plate 40, and the calibration groove 41 is located between the two guiding inclined surfaces 42. A cylinder 43 is hinged to the frame 1. The telescopic shaft 44 of the cylinder 43 is hinged to an adjusting rod 45. One end of the adjusting rod 45 away from the telescopic shaft 44 is fixedly connected to a connecting shaft 46. The connecting shaft 46 is horizontally arranged and is rotatably connected to the frame 1. A connecting frame 47 is fixedly connected to the end of the connecting shaft 46. A roller 48 is rotatably connected to the connecting frame 47. The roller 48 is used to be embedded in the calibration groove 41. The roller 48 is located on the side of the feeding assembly 20 away from the cutting mechanism 33.

[0046] First, the servo motor drives the two rotating wheels 6 located at both ends of the support plate 2 to rotate. Through the driving chain 7 connected to the rotating wheels 6, a plurality of conveying plates 4 on the kidney-shaped track 3 are driven to continuously move along the track. Each conveying plate 4 is accurately restricted on the kidney-shaped track 3 by the four limiting wheels 5 thereon to ensure smooth operation.

[0047] 1. Feeding stage: When the transfer board 4 moves to the position of the feeding assembly 20, the elastic clamping mechanism 8 thereon starts to cooperate with the feeding assembly 20. At this time, a plurality of first connecting wheels 21 on the first clamping plate 12 and a plurality of second connecting wheels 22 on the second clamping plate 13 will respectively contact a plurality of third connecting wheels 23 arranged in parallel on the feeding plate 24. As the transfer board 4 continues to move, the third connecting wheels 23 exert a squeezing force on the first connecting wheels 21 and the second connecting wheels 22, and this force forces the first clamping plate 12 and the second clamping plate 13 to slide outward along the slide rod 10, overcoming the elastic force of the elastic member, thereby opening the clamping area. At the same time, the calibration plate 40 on the side wall of the transfer board 4 is driven by the cylinder 43, and the calibration groove 41 thereon is precisely matched with the roller 48 to calibrate and lock the position of the transfer board 4, ensuring that the clamping mechanism can accurately align with the feeding position when it opens. At this time, the cocoons fall into the clamping area formed by the opened first clamping groove 14 and the second clamping groove 15. Once the transfer board 4 moves out of the action range of the third connecting wheels 23, the squeezing force disappears, and the elastic force of the elastic member immediately springs the first clamping plate 12 and the second clamping plate 13 back, automatically clamping the cocoons stably in the clamping area. Both ends of the limiting plate 16 will abut against the bottom walls of the first limiting groove 17 and the second limiting groove 18 to prevent the clamping plates from approaching too closely.

[0048] 2. Cutting stage: After clamping the cocoons, the transfer board 4 continues to move along the kidney-shaped track 3, bringing the cocoons under the cutting mechanism 33. At this time, the cutting motor 35 on the fixed plate 34 drives the cutter 36 to rotate at a high speed to precisely cut the cocoons clamped between the first clamping plate 12 and the second clamping plate 13. After cutting is completed, the transfer board 4 continues to move forward.

[0049] 3. Discharging stage: When the transfer board 4 moves to the position of the discharging assembly 25, a plurality of first connecting wheels 21 on the first clamping plate 12 and a plurality of second connecting wheels 22 on the second clamping plate 13 will respectively contact the first inclined surface 37 and the second inclined surface 38 on the expansion plate 27. As the transfer board 4 moves, the inclined surfaces exert an outward thrust on the connecting wheels, again forcing the first clamping plate 12 and the second clamping plate 13 to expand to both sides, opening the clamping area. At this time, the cut cocoons fall freely due to the loss of clamping and are received by the transmission mechanism 28 located below the expansion plate 27.

[0050] 4. Transmission stage: The fallen cocoons land on the conveyor belt 31 of the transmission mechanism 28 and are supported by a plurality of connecting plates 39 on its surface. The discharging motor 30 drives the conveying roller 32 to rotate, driving the conveyor belt 31 to move in a cycle, and smoothly conveying the cocoons to the designated position.

[0051] This entire cycle repeats, and each conveyor plate 4 independently completes the entire process of loading, clamping, cutting, unloading, and conveying, thus achieving efficient, automated, and continuous production of the cocoon separation process.

[0052] Embodiment 2: The present invention also discloses a method for automatically separating cocoons. An automatic cocoon separation device in Embodiment 1 includes the following steps: S1. Use the elastic clamping mechanism 8 to adaptively clamp and position a single cocoon. S2. Drive the elastic clamping mechanism 8 to move along the preset kidney-shaped track 3 through the power system, so that the clamped cocoon passes through the cutting mechanism 33, and the cutting mechanism 33 cuts a notch on the cocoon shell. S3. Continue to drive the elastic clamping mechanism 8 to move until it reaches the horizontally inverted state along the kidney-shaped track 3, and use the gravity to make the silkworm pupae in the cocoon slide out of the cocoon shell through the notch and fall. S4. After the silkworm pupae fall, control the elastic clamping mechanism 8 to release the clamping force, so that the cut empty cocoon shell falls due to gravity, thereby completing the automatic separation and classification of the silkworm pupae and the cocoon shell.

[0053] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
