Description

Technical Field

[0001] This invention belongs to the field of silkworm cocoon processing, specifically relating to a discharge auxiliary mechanism applied to a silkworm cocoon-shaving machine, which can assist in the feeding of unshaving silkworms and the discharge of shaving silkworms. Background Technology

[0002] Traditional silkworm rearing methods are small-scale family-run operations, typically using small bamboo baskets for feeding. These baskets are simple in structure, easy to manufacture, and can be hand-woven, resulting in low costs. This small-scale rearing method is entirely manual, requiring human intervention from egg to adult to cocoon harvesting. It is time-consuming, labor-intensive, and has very low efficiency. Furthermore, it is limited by seasonal conditions, allowing silkworms to be raised only at specific times, resulting in extremely low annual cocoon production. This method cannot meet the needs of modern society and has been gradually phased out.

[0003] To overcome the shortcomings of traditional workshop-style silkworm rearing, large-scale silkworm rearing technology has emerged. This technology employs centralized rearing methods and improves efficiency through feed development, enabling continuous silkworm rearing 365 days a year and producing a large number of cocoons daily. The cocoons need to be reeled to obtain silk, and before reeling, the cocoons need to be trimmed to prepare them for the reeling process. Currently, cocoon trimming is generally done manually or with a combination of manual and machine work. These methods are not only inefficient, unable to handle the large volume of cocoons produced daily, thus limiting reeling efficiency and affecting silk production, but also require a significant investment of manpower, are time-consuming, labor-intensive, costly, and pose certain safety hazards.

[0004] Therefore, there is an urgent need to develop a dedicated device for cocoon removal, capable of continuous and automated cocoon removal. To achieve this goal, how to clamp the cocoons tightly to complete the removal process is a crucial problem that needs to be solved. If the cocoons are clamped too tightly, they are easily damaged; if they are clamped too loosely, they are prone to loosening, affecting the removal process. To address this, a needle-plate device was designed to clamp the cocoons using the rebound force of elastic needles. However, in actual production, it was found that to ensure the clamping effect, the width of the elastic clamping channel of the needle-plate device should be smaller than the width of the cocoon, but this results in inconvenience for cocoon loading and unloading. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary feeding and discharging mechanism for a silkworm cocoon cutting machine. In view of the defects in the prior art, a mechanism specifically designed to assist in feeding and discharging silkworm cocoons is designed. It includes a swing component and an auxiliary component. The swing component drives the auxiliary component to swing back and forth. During the swinging process, the feeding and discharging positions of the needle plate device are repeatedly opened or closed, thereby assisting in feeding and discharging silkworm cocoons.

[0006] To solve the above-mentioned technical problems, the following technical solution is adopted.

[0007] A feeding and discharging auxiliary mechanism for a silkworm cocoon cutting machine is characterized in that: the feeding and discharging auxiliary mechanism includes a swing component and an auxiliary component, the swing component is used to drive the auxiliary component to swing back and forth, and the auxiliary component swings back and forth to open or close the needle plate device at the feeding and discharging position, thereby assisting the silkworm cocoons to be fed and discharged in the needle plate device.

[0008] Furthermore, the auxiliary components include a support component, which reciprocates by swinging the needle plate device at the discharge position to assist in the discharge of silkworm cocoons after they have been shorn.

[0009] Furthermore, the auxiliary components include a support upper part, which reciprocates by swinging the needle plate device at the feeding position to assist in feeding uncut silkworm cocoons into the needle plate device.

[0010] Furthermore, the auxiliary components include a needle plate support, which is used to mount the support component and the support upper component, and connects to the swing component, which drives the support component and the support upper component to swing.

[0011] Furthermore, the needle plate support has an arc-shaped opening, which serves a supporting function.

[0012] Furthermore, at least two sets of auxiliary components are provided.

[0013] Furthermore, the swing assembly includes a swing shaft, an eccentric swing wheel, a swing rod, and a swing component. The swing shaft drives the eccentric swing wheel, the eccentric swing wheel is connected to the swing rod, the swing rod is hinged to the swing component, and drives the swing component to swing. The swing component is connected to and drives the auxiliary component to swing.

[0014] Furthermore, the swing component includes a connecting rod, a connecting shaft, and a swing member. The swing rod is hinged to the connecting rod, one end of the connecting rod is hinged, and the other end is connected to the connecting shaft. The connecting shaft is connected to the swing member, and the swing member is connected to the auxiliary component, which drives the auxiliary component to swing.

[0015] Furthermore, at least two swinging components are provided.

[0016] Furthermore, the eccentric oscillating wheel includes an eccentric oscillating component, an oscillating bearing, and an oscillating wheel housing. The oscillating bearing is sleeved on the eccentric oscillating component, and the oscillating wheel housing is sleeved on the oscillating bearing. The eccentric oscillating component rotates eccentrically, which is converted into a reciprocating push-pull motion through the oscillating bearing.

[0017] The above technical solution has the following beneficial effects:

[0018] This invention designs a mechanism specifically for assisting in the feeding and discharging of silkworm cocoons. It includes a swing component and an auxiliary component. The swing component drives the auxiliary component to swing back and forth. During the swinging process, the feeding and discharging positions of the needle plate device are repeatedly opened or closed, thereby assisting in the feeding and discharging of silkworm cocoons.

[0019] The auxiliary components include a needle plate support, an upper support, and a smaller support. The smaller support and the upper support swing back and forth. The smaller support opens or closes the elastic channel at the discharge position through the swinging motion, assisting in the discharge of silkworm cocoons after they have been peeled. The upper support opens or closes the elastic channel at the feeding position through the swinging motion, assisting in the feeding of unpeeled silkworm cocoons into the needle plate device, thereby improving the success rate of feeding and discharging.

Detailed Implementation

[0038] The present invention aims to provide a mechanism specifically for assisting in the feeding and discharging of silkworm cocoons. It includes a swing component and an auxiliary component. The swing component drives the auxiliary component to swing back and forth. During the swinging process, the feeding and discharging positions of the needle plate device are repeatedly opened or closed, thereby assisting in the feeding and discharging of silkworm cocoons.

[0039] The feeding and discharging auxiliary mechanism of the present invention is applied to a silkworm cocoon cutting machine. The present invention and the cocoon cutting machine are described in detail below with reference to specific embodiments.

[0040] like Figure 1 As shown, the cocoon-stripping machine includes a frame 1 and a conveying mechanism 2, a needle plate device 4, a cocoon-stripping mechanism 5, a pushing mechanism 3, an infeed / outfeed auxiliary mechanism 7, and a synchronous drive mechanism 8, all mounted on the frame 1. These mechanisms cooperate to complete an automated, continuous cocoon-stripping operation. The following is a detailed description of each mechanism:

[0041] Conveying mechanism 2 is used to automatically and continuously supply silkworm cocoons to needle plate device 4, such as... Figures 3 to 5As shown, the conveying mechanism 2 includes a chain drive assembly and a guide rail assembly. The chain drive assembly includes a first chain 22, a motor unit (not shown in the figure) that drives the first chain 22, a first driving sprocket 23, a first driven sprocket 24, and several tension sprockets 25. The first chain 22 is driven by the transmission action of the motor unit, the first driving sprocket 23, and the first driven sprocket 24. The first chain 22 is provided with partitions 221, which are evenly spaced. With the pushing action of the partitions 221, the first chain 22 can drive the cocoons forward. However, since the first chain 22 does not have a limiting function, the cocoons are prone to falling off the first chain 22. Therefore, a guide rail assembly is provided to cooperate with the chain. The guide rail assembly includes a guide rail 26, such as... Figure 4 As shown, the guide rail 26 is set on the left and right sides of the first chain 22, and the three together form the guide rail groove 27. The guide rail groove 27 limits the silkworm cocoon, so that the silkworm cocoon can be stably transported to the needle plate device 4 under the push of the first chain 22.

[0042] To improve efficiency, the first chain 22 has n sections, and the guide rail 26 has n+1 sections, forming n guide rail grooves 27, where n≥2. The number of first chains 22 can be adjusted according to actual production conditions, and multiple first chains 22 can be driven synchronously. To match the first chains 22, the number of guide rails 26 should be one more than the number of chains, so as to form guide rail grooves 27 with the same number as the first chains 22.

[0043] The conveying mechanism 2 of this invention consists of a chain drive assembly and a guide rail assembly. The chain drive assembly drives the chain to run, and the running chain can transport silkworm cocoons. The guide rail assembly forms guide rail grooves 27 by setting guide rails 26. The guide rail grooves 27 are used to limit the silkworm cocoons, so that they are transported in a directional and stable manner under the drive of the chain. The structure is ingeniously designed and practical. To improve efficiency, multiple chains can be set, and synchronously driving these chains can realize batch transport of silkworm cocoons, further improving the efficiency of cocoon cutting.

[0044] The conveying mechanism 2 also includes a feeding assembly 21, which includes a feeding shaft 211 and feeding blades 212 connected to the feeding shaft 211. The feeding blades 212 are driven to rotate by the feeding shaft 211, and during the rotation, they push the cocoons into the guide rail groove 27. The feeding assembly 21, through the rotating feeding blades 212, pushes the cocoons into the guide rail groove 27, and prevents cocoons that have not entered the guide rail groove 27 from passing through, forcing the cocoons into the guide rail groove 27. Depending on the actual production needs, multiple sets of feeding assemblies 21 can be set. In this embodiment, two sets are set. Compared with one set of feeding assemblies 21, the feeding effect is significantly improved, and almost all cocoons can fall into the guide rail groove 27. Depending on the actual production needs, each set of feeding assemblies 21 can have 2-8 feeding blades 212. In this embodiment, 2 blades are set to complete the feeding operation.

[0045] The pushing mechanism 3 is used to directionally push the silkworm cocoons in the conveying mechanism 2 into the needle plate device 4, such as... Figure 7-9 As shown, the pushing mechanism 3 includes a cam assembly, a push-pull assembly, and a push-swing rod assembly. The cam assembly is used to drive the push-swing rod assembly to rotate back and forth, and the push-pull assembly is used to drive the push-swing rod assembly to move back and forth. The cam assembly and the push-swing assembly operate synchronously, and the two work together to realize the push-swing rod to push back and forth, and complete the pushing operation during the reciprocating pushing process.

[0046] The cam assembly includes a camshaft 31 and cams 32. The camshaft 31 is synchronously driven by a synchronous drive mechanism 8. Multiple cams 32 are connected to the camshaft 31 to drive the cams 32 to rotate, such as... Figure 7 As shown in this embodiment, three cams 32 are provided; during the rotation of the cams 32, their protruding ends reciprocate to push the push-rocker assembly, thereby driving the push-rocker assembly to rotate reciprocally.

[0047] The push-pull assembly has two sets, located on the left and right sides of the camshaft 31 respectively. Each push-pull assembly includes an eccentric push-pull wheel 33, a push-pull rod 34, a push-pull mounting plate 35, and a cocoon-pushing mechanism shaft 36. The eccentric push-pull wheel 33 is synchronously driven by the camshaft 31. The eccentric push-pull wheel 33 includes a push-pull eccentric component 331, a push-pull bearing 332, and a push-pull wheel housing 333. The push-pull eccentric component 331 is synchronously driven by the camshaft 31 to rotate eccentrically, converting the eccentric rotation into a non-linear push-pull motion, which is then transmitted to the push-pull rod 34. The push-pull rod 34 is hinged to the push-pull mounting plate 35, converting the non-linear push-pull motion into a linear push-pull motion of the mounting plate 35. The push-pull mechanism shaft 36 connects the left and right push-pull mounting plates 35, transmitting the linear push-pull motion to the shaft. The push-pull mechanism shaft 36 drives the push-swing rod assembly to move back and forth. The push-pull mechanism shaft 36 is hinged and can rotate. In addition, the push-pull mounting plate 35 is also connected to a guide slider 352, which slides on the guide rail 351. The guide rail 351 is fixedly installed, and the two serve to guide the push-pull mounting plate 35, enabling it to move back and forth stably.

[0048] The push-swing rod assembly includes a push-swing rod 37 and a push plate 38. Three push-swing rods 37 are mounted on the cocoon-pushing mechanism shaft 36, corresponding one-to-one with the cams 32. The push-swing rods 37 and the cocoon-pushing mechanism shaft 36 are rotatably connected. The cams 32 can push the push-swing rods 37 to rotate, and the push-swing rods 37 and the cocoon-pushing mechanism shaft 36 have a reset function, allowing them to reciprocate under the reciprocating push of the cams 32. The push-pull assembly can push the push-swing rods 37 to move back and forth. The push-swing rods 37 are connected to the push plate 38, which drives the push plate 38 to reciprocate. The push plate 38 has several push pieces 381, which are evenly spaced. The number of push pieces 381 is the same as the number of push pieces 381 on the first chain 22. Each push piece 381 is used to push the cocoon on the corresponding first chain 22. The width of the push piece 381 is smaller than the width of the guide groove 27, allowing it to enter the guide groove 27 and push the cocoon into the needle plate device 4 through the pushing action.

[0049] The feeding mechanism 3 of the present invention consists of a cam assembly, a push-pull assembly and a push-rocker assembly. The cam assembly includes a cam 32 and a camshaft 31 that drives the cam 32 to rotate. The convex end of the rotating cam 32 repeatedly pushes the push-rocker 37, causing the push-rocker 37 to rotate back and forth. Through this back-and-forth rotation, the push plate 38 reciprocates in and out of the guide rail groove 27. When entering the guide rail groove 27, it performs feeding. When exiting the guide rail groove 27, it allows the next silkworm cocoon to enter the feeding position. The eccentric push-pull wheel 33 of the push-pull assembly is driven by the camshaft 31 to rotate synchronously. Based on its eccentric characteristic, it can reciprocate to push and pull the push-pull rod 34 during rotation. Through the hinged connection, it realizes the reciprocating horizontal back-and-forth swing of the push-pull mounting plate 35 and the cocoon pushing mechanism shaft 36, thereby driving the push swing rod 37 and the push plate 38 to reciprocate horizontal back-and-forth swing. The cam assembly and the push-pull assembly cooperate with each other. When the push plate 38 enters the guide rail groove 27, the push-pull assembly pushes the push plate 38 forward, pushing the cocoon into the needle plate device 4. When the push plate 38 exits the guide rail groove 27, the push-pull assembly pulls the push plate 38 backward, preparing for the next push. This push mechanism 3 can realize automatic reciprocating push, connecting the conveying mechanism 2 and the cocoon cutting mechanism 5, which helps to improve the cocoon cutting efficiency.

[0050] The needle plate device 4 is used to convey silkworm cocoons, such as... Figure 10 and Figure 12As shown, it includes elastic needles 42, needle plate pressure plates 41, and a needle plate main shaft 43. The needle plate main shaft 43 is synchronously driven by a synchronous drive mechanism 8. The needle plate pressure plates 41 are connected to the needle plate main shaft 43 and are evenly spaced. Each needle plate pressure plate 41 has elastic needles 42 arranged in its circumferential direction, and the elastic needles 42 are arranged at equal angles. The elastic needles 42 of two adjacent needle plate pressure plates 41 form elastic channels 44, which are used to clamp the cocoons. The needle plate main shaft 43 drives the elastic needles 42 to rotate, thereby clamping and rotating the cocoons. The number of elastic channels 44 is the same as the number of first chains 22, that is, each cocoon on the first chain 22 is pushed into the corresponding elastic channel 44.

[0051] The needle plate device 4 is equipped with regularly arranged elastic needles 42. The elastic needles 42 are arranged in rows, and each row of elastic needles 42 is arranged circumferentially. An elastic channel 44 is formed between two adjacent rows of elastic needles 42. The width of the elastic channel 44 is smaller than the width of the silkworm cocoon. After the silkworm cocoon enters the elastic channel 44, it is subjected to the rebound force from the elastic needles 42, thereby clamping the silkworm cocoon. This not only clamps it stably, but also makes it easy to remove and collect it.

[0052] In practical use, it was found that the width of the elastic clamp 44 needs to be smaller than the width of the cocoon in order to clamp the cocoon tightly. However, in this case, it is inconvenient for the cocoon to enter and exit the elastic clamp 44. Therefore, an infeeding and discharging auxiliary mechanism 7 was designed. This infeeding and discharging auxiliary mechanism 7 opens or closes the elastic clamp 44 at the infeeding and discharging position by swinging motion, which assists the cocoon in feeding and discharging in the needle plate device 4.

[0053] like Figure 10 , Figure 11 and Figure 13As shown, the feeding / discharging auxiliary mechanism 7 includes a swing component and an auxiliary component. The swing component drives the auxiliary component to swing back and forth. The auxiliary component swings and reciprocates to open or close the elastic clamps 44 at the feeding / discharging position, assisting the silkworm cocoons in feeding and discharging within the needle plate device 4. The auxiliary component includes a needle plate support 77 and a small support 79 connected to the lower end of the needle plate support 77 and an upper support 78 connected to the upper end. The needle plate support 77 has an inwardly concave arc shape on its inner side, providing a certain support function. The width of the upper support 78 is greater than the width of the elastic clamps 44. It is embedded in the corresponding elastic clamps 44 and can open the elastic clamps 44. During the swinging process, the elastic clamps 44 at the feeding position are repeatedly opened and closed. When opened, the silkworm cocoons can be easily pushed into the elastic clamps 44. When closed and reset, the elastic clamps 44 clamp the fed silkworm cocoons, thereby achieving the purpose of assisting feeding and improving the feeding success rate. The width of the support component 79 is greater than the width of the elastic channel 44. It is embedded in the corresponding elastic channel 44 and can open the elastic channel 44. During the swinging process, the elastic channel 44 at the discharge position is repeatedly opened and closed. When it is opened, the silkworm cocoons that have been peeled can easily fall out of the elastic channel 44, improving the success rate of discharge.

[0054] The swing assembly includes a swing shaft 71, an eccentric swing wheel 72, a swing pull rod 73, a connecting rod 74, a connecting shaft 75, and a swing element 76. The swing shaft 71 is synchronously driven by a synchronous drive mechanism 8. The swing shaft 71 drives the eccentric swing wheel 72, which includes an eccentric swing element 721, a swing bearing 722, and a swing wheel housing 723. The eccentric swing element 721 is synchronously driven by the swing shaft 71 to rotate eccentrically. The eccentric rotation motion is converted into a non-linear push-pull motion and transmitted to the swing pull rod 73 through the swing bearing 722. The swing pull rod 73 is hinged to the connecting rod 74. Under the hinged connection, the push-pull motion is converted into the reciprocating swing motion of the connecting rod 74. One end of the connecting rod 74 is hinged, and the other end is connected to the connecting shaft 75, which drives the connecting shaft 75 to rotate reciprocally, thereby driving the swing element 76 to swing reciprocally. The oscillating component 76 is connected to the needle plate support component 77 and is used to drive the needle plate support component 77 to oscillate back and forth, thereby achieving the purpose of assisting in feeding and discharging materials.

[0055] The number of auxiliary components is the same as the number of elastic channels 44. Each auxiliary component acts on the corresponding elastic channel 44. The corresponding number of swinging members 76 is also the same. Each swinging member 76 is used to drive the corresponding auxiliary component to swing.

[0056] The needle plate support 77 of the present invention can reciprocate under the push of the swing assembly. During the swing, the support small part 79 and the support upper part 78 reciprocate. The support small part 79 opens or closes the elastic channel 44 at the discharge position through the swing action to assist the discharge of silkworm cocoons after they have been peeled. The support upper part 78 opens or closes the elastic channel 44 at the feed position through the swing action to assist the feed of unpeeled silkworm cocoons into the needle plate device 4, thereby improving the success rate of feeding and discharging.

[0057] The cocoon-shaving mechanism 5 works in conjunction with the needle plate device 4 to complete the cocoon-shaving operation during the conveying process. For example... Figure 14 As shown, it includes a cocoon-shaving motor unit 51, a cutting shaft 52, and a cutting blade 53. The cocoon-shaving motor unit transmits power to the cutting shaft 52 via a drive wheel 54, a driven wheel 55, and a belt 56, causing the cutting shaft to rotate. The cutting shaft 52 is connected to the cutting blade 53, and the rotating cutting blade 53 is used to shave the cocoons. The number of cutting shafts 52 and cutting blades 53 is the same as the number of elastic channels 44. Each cutting blade 53 is used to shave the cocoons in the corresponding elastic channel 44. Each cutting shaft 52 is connected to a synchronous pulley (not shown in the figure), and all cutting shafts 52 can be driven to rotate synchronously by connecting a synchronous belt 57.

[0058] The cocoon-stripping machine also includes two conveyor belts, namely a first conveyor belt 61 and a second conveyor belt 62. Figure 1 As shown, the first conveyor belt 61 is oriented in the same direction as the conveying mechanism 2. After the cocoons are cut, they are further conveyed by the needle plate device 4, with the cutting opening gradually facing downwards. When it reaches a certain downward position, the silkworm pupae inside fall off and are collected and sent out by the first conveyor belt 61. The second conveyor belt 62 is oriented perpendicular to the conveying mechanism 2 and is located below the auxiliary components. It can collect the fallen cocoons and send them out.

[0059] Synchronous drive mechanism 8 is used to synchronously drive needle plate device 4, pusher mechanism 3 and feeding / discharging auxiliary mechanism 7, such as Figure 15 and Figure 16As shown, it includes a synchronous motor assembly 81, a gear assembly, and a sprocket assembly. The gear assembly includes a driving gear 82, a transmission gear 83, a first driven gear 84, and a second driven gear 85. The synchronous motor assembly 81 drives the driving gear 82 to rotate. The driving gear 82 meshes with the transmission gear 83, driving the transmission gear 83 to rotate. The transmission gear 83 meshes with the first driven gear 84 and the second driven gear 85, driving the first driven gear 84 and the second driven gear 85 to rotate. The first driven gear 84 is mounted on the camshaft 31, achieving synchronous drive of the camshaft 31 to rotate. Two driven gears 85 are mounted on the swing shaft 71 to synchronously drive the swing assembly; the transmission gear 83 is connected to a transmission sprocket 87 on the other side via the transmission shaft 86. The transmission sprocket 87 drives the second sprocket 88 to rotate via the second chain 89. The second sprocket 88 is connected to the needle plate main shaft 43 to synchronously drive the needle plate main shaft 43 to rotate. The other end of the needle plate main shaft 43 is connected to a third sprocket (not shown in the figure). The third sprocket synchronously drives the fourth sprocket 90 via the third chain 91. The fourth sprocket 90 is connected to the first belt line 61 to synchronously drive the first belt line 61 to rotate.

[0060] This invention employs a synchronous drive mechanism 8 to synchronously drive the needle plate device 4, the pushing mechanism 3, and the feeding / discharging auxiliary mechanism 7, enabling all components to operate synchronously. This not only coordinates the actions of each component, allowing them to precisely cooperate in completing actions such as pushing, feeding / discharging assistance, and conveying, but also avoids the problem of difficulty in accurately coordinating to complete corresponding processes due to independent operation. Furthermore, it reduces the number of motors and lowers costs.

[0061] The cocoon-removing process of this invention is as follows:

[0062] 1. First, put the silkworm cocoons onto the conveyor mechanism 2. This process can be done manually or automatically by using the feeding head.

[0063] 2. Some silkworm cocoons directly enter the guide rail groove 27, while the remaining silkworm cocoons gradually enter the guide rail groove 27 under the action of the feeding component 21. The silkworm cocoons that enter the guide rail groove 27 are further conveyed forward.

[0064] 3. When the silkworm cocoons are conveyed to the feeding position, the pushing mechanism 3, together with the feeding and discharging auxiliary mechanism 7, pushes the silkworm cocoons into the elastic clamp 44 of the needle plate device 4 in sequence.

[0065] 4. The elastic clamp 44 clamps the silkworm cocoon and rotates it. When it rotates to the cocoon-shaving mechanism 5, it shaves the cocoon and removes the upper end of it.

[0066] 5. After the cocoon is removed, it gradually rotates downwards, and the silkworm pupa inside falls onto the first belt conveyor 61. When the cocoon reaches the support piece 79, it falls onto the second belt conveyor 62.

[0067] 6. Repeat the above process to achieve automated and continuous cocoon removal.

[0068] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
