Description

Technical Field

[0001] This application relates to the field of shell processing technology, and in particular to a sorting device for processing shell handicrafts. Background Technology

[0002] Mussels such as limpets and abalone shells have a unique pearly luster (iridescence effect) and distinctive textures, and each shape is unique, making them highly ornamental and artistic. They are often used to make handicrafts or decorations. Since different sizes or thicknesses of shells can be used to make different handicrafts, and the value of the finished products also varies, especially for larger shells, which generally have greater economic value, the shells are first sieved during processing to divide them into multiple equal parts of different sizes. Each part of the shells is similar in size to be processed into corresponding handicrafts.

[0003] In related technologies, the traditional method for sorting shellfish of different sizes is manual sieving. However, this method relies heavily on the subjective judgment of workers, resulting in low sieving efficiency and accuracy, and requires a large amount of manpower. Another method involves automatic sieving using a sorting device with a machine vision system. This device requires high-resolution industrial cameras to capture images during the sorting process. However, machine vision systems are easily affected by residual water stains, mucus reflections, and changes in ambient light on abalone shells, which can affect sorting accuracy. Furthermore, since shellfish are seafood, the high humidity environment during sorting is not conducive to such high-precision equipment. Therefore, the device is prone to failure, and once a failure occurs, repair is difficult, affecting sorting efficiency. Summary of the Invention

[0004] This application aims to propose a sorting device for processing seashell handicrafts, in order to solve the technical problems of low sorting efficiency and sorting accuracy in the process of sorting seashells of different sizes in related technologies.

[0006] In some embodiments, the housing is provided with a limiting cavity located above the through cavity and communicating with the guide channel. The thickness sorting assembly includes a sorting adjustment box disposed in the limiting cavity and slidably connected to the housing in a third direction, and a transmission member extending to the limiting cavity and the guide channel at both ends respectively. The transmission member is slidably connected to the housing in the first direction. The bottom of the sorting adjustment box is connected to a sorting plate located in the through cavity. A shell sorting area is formed between the sorting plate and the guide conveyor plate. The sorting adjustment box is configured to drive the transmission member to move in the first direction when a shell that meets the corresponding thickness value passes through the shell sorting area, so as to control the opening and closing of the hinge plate.

[0007] In some embodiments, the transmission member has an inclined surface on the side near the sorting adjustment box, and a roller that abuts against the inclined surface is provided on one side of the sorting adjustment box. When the sorting adjustment box slides upward along the third direction, the roller squeezes the inclined surface to push the transmission member to slide along the first direction.

[0008] In some embodiments, the bottom of the sorting adjustment box is provided with a limiting groove with an opening facing the guide conveyor plate, and a nut is provided at the bottom of the limiting groove. A portion of the sorting plate extends into the limiting groove and is provided with an adjusting bolt threadedly connected to the nut. The adjusting bolt is configured to adjust the relative distance between the sorting plate and the guide conveyor plate.

[0009] In some embodiments, the hinge plate has a slot and an arcuate surface near the slot at the end opposite to the end rotatably connected to the housing. The transmission member extends to the end near the hinge plate and has a locking part. The locking part is rotatably connected to a roller adapted to the arcuate surface. The locking part is configured to be selectively slidable along the first direction to extend into or out of the slot, thereby locking or releasing the hinge plate.

[0010] In some embodiments, one end of the hinge shaft of the hinge plate extends out of the housing and is connected to a gear. A rack is provided on the side of the chain near the guide conveyor plate, which indirectly meshes with the gear. The rack is configured to reset the hinge plate in the open state to lock with the latching part via the gear.

[0011] In some embodiments, the rack has a limiting groove arranged along the first direction, and the end face of the housing near the gear is provided with a roller assembly adapted to the limiting groove. The roller assembly is configured to cooperate with the limiting groove to guide and limit the movement of the rack.

[0012] In some embodiments, the top surface of the sorting adjustment box is provided with a first elastic element connected to the top surface of the limiting cavity, and the side end face of the transmission member away from the sorting adjustment box is provided with a second elastic element connected to the side surface of the limiting cavity.

[0014] In some embodiments, one end of the two limiting plates is provided with a bent section, and the flared portion of the conveying channel is formed between the two bent sections.

[0015] Compared with the prior art, at least one or more technical solutions provided in this application have the following beneficial effects: The sorting device provided in this application comprises a guide conveyor plate, a drive shaft, and a chain arranged in a shell conveying mechanism. A pusher block is provided on the side of the chain near the guide conveyor plate. When the drive shaft drives the chain to rotate, it drives the pusher block to move along a first direction and push the shells on the guide conveyor plate. Then, a sorting mechanism is provided through a notch in the guide conveyor plate. The sorting mechanism includes a box and a thickness sorting component disposed in the box. The box has a cavity for shells to pass through and a guide channel for collecting sorted shells. The bottom surface of the cavity is coplanar with the top surface of the guide conveyor plate. A hinged plate is rotatably connected to the bottom surface of the cavity. A part of the thickness sorting component forms a shell screening area between itself and the guide conveyor plate. When shells that meet the thickness requirements are pushed into the cavity, the thickness sorting component controls the rotation of the hinged plate to connect the cavity with the guide channel, so that the shells that meet the thickness requirements are screened and fall into the guide channel, completing the screening. At the same time, multiple sorting mechanisms can be arranged on the guide conveyor plate along the first direction to achieve precise sorting of shells of different thicknesses simultaneously.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0025] Please see Figures 1 to 7 This embodiment provides a sorting device for processing seashell handicrafts. The sorting device 100 is used to sort limpets or abalone shells to screen seashells of different sizes and make different handicrafts. The sorting device 100 includes a support platform 10, a seashell conveying mechanism 20, and a sorting mechanism 30. The support platform 10 can be rectangular to support the seashell conveying mechanism 20 and the sorting mechanism 30. For ease of description, the length direction of the support platform 10 is defined as the first direction A, the width direction of the support platform 10 is defined as the second direction B, and the height direction of the support platform 10 is defined as the third direction C. The seashell conveying mechanism 20 is disposed on the support platform 10 and includes a protective shell 21, a drive shaft 22, a gear 3144, a chain 24, and a guide conveying plate 25. Two protective shells 21 are spaced apart on both sides of the top of the support platform 10 along the second direction B, and the protective shells 21 are fixed to the support platform 10. The drive shaft 22 is arranged along the second direction B, and its two ends are rotatably connected to the protective shell 21. At the same time, the two drive shafts 22 are spaced apart in the first direction A. Each drive shaft 22 has two sprockets 23 spaced apart along the second direction B. Chains 24 are respectively located on both sides of the drive shaft 22 and connected to the two sprockets 23 in the first direction A. A guide conveyor plate 25 is located between the two chains 24 and connected to the two drive shafts 22 at both ends. The guide conveyor plate 25 is relatively stationary to the two drive shafts 22, that is, when the two drive shafts 22 rotate, the guide conveyor plate 25 remains stationary. At least one of the chains 24 on both sides is provided with a pusher block 241 for pushing the shell on the side close to the guide conveyor plate 25. The pusher block 241 moves with the rotation of the chain 24. When a shell is placed on the guide conveyor plate 25, the pusher block 241 moves close to the upper surface of the guide conveyor plate 25 along the first direction A, thereby driving the shell to move.

[0026] It should be noted that, in order to achieve automatic control of the operation of the shell conveying mechanism 20, the shells can be transferred to the guide conveyor plate 25 by means of a belt conveyor. At the same time, a pulley 221 can be set on one side of one of the drive shafts 22. A drive component 11 can be fixedly installed at the bottom of the support platform 10. The drive component 11 can be one of various types of motors, which can be selected according to actual needs. The output shaft of the drive component 11 is connected to the pulley 221 through the conveyor belt, thereby driving the shell conveying mechanism 20 to run.

[0027] Furthermore, in combination Figure 2 and Figure 3 The guide conveyor plate 25 is provided with at least one notch 251 spaced apart along the first direction A. At least one sorting mechanism 30 is disposed in the notch 251. The notch 251 is opened through the guide conveyor plate 25 along the third direction C. The sorting mechanism 30 includes a box 31 and a thickness sorting component 32 disposed in the box 31. The box 31 is provided with a cavity 311 for shells to pass through and a guide channel 312 for collecting sorted shells. The bottom surface of the cavity 311 is coplanar with the top surface of the guide conveyor plate 25. A hinge plate 314 is rotatably connected to the bottom surface of the cavity 311. The thickness sorting component 32 is configured to selectively control the rotation of the hinge plate 314 according to the thickness of the shells, so as to sort the shells that meet the corresponding thickness value from the cavity 311 to fall into the guide channel 312.

[0028] Specifically, in combination Figure 4 The housing 31 is provided with a limiting cavity 313 located above the through cavity 311 and connected to the guide channel 312. The thickness sorting component 32 includes a sorting adjustment box 321 disposed in the limiting cavity 313 and slidably connected to the housing 31 in the third direction C, and a transmission component 322 extending to the limiting cavity 313 and the guide channel 312 at both ends respectively. The transmission component 322 is slidably connected to the housing 31 in the first direction A. The bottom of the sorting adjustment box 321 is connected to a sorting plate 323 located in the through cavity 311. A shell sorting area is formed between the sorting plate 323 and the guide conveyor plate 25. The sorting adjustment box 321 is configured to drive the transmission component 322 to move in the first direction A when a shell that meets the corresponding thickness value passes through the shell sorting area, so as to control the opening and closing of the hinge plate 314.

[0029] It should be understood that the through cavity 311 is arranged through the first direction A, and the through cavity 311 is separated from the limiting cavity 313 by a partition. The through cavity 311 is used for the installation of the sorting adjustment box 321 and the sorting adjustment box 321 is connected to the hinge plate 314 through the transmission component 322. When the sorting adjustment box 321 moves along the third direction C, it drives the transmission component 322 to move in the first direction A, thereby controlling the hinge plate 314 to open or close. At the same time, the sorting adjustment box 321 can also adjust the spacing between the sorting plate 323 and the guide conveyor plate 25 to form the shell sorting area, thereby realizing the sorting of shells of different thicknesses by the same sorting mechanism 30. The sorting plate 323 can be a short plate parallel to the guide conveyor plate 25, and the front end of the sorting plate 323 can be rounded to facilitate the shells to enter the shell sorting area between the sorting plate 323 and the guide conveyor plate 25.

[0030] It should be noted that multiple notches can be set, and a sorting mechanism 30 can be set at each notch. For multiple sorting mechanisms 30 along the flow direction of the shells, different sorting standards can be set. However, it is necessary to ensure that in the flow direction, the multiple sorting mechanisms 30 sort the shells in the order of increasing thickness. For example, in this embodiment, there are two sorting mechanisms 30. The first sorting mechanism 30 can be set to screen shells with a thickness of 8cm, and the second sorting mechanism 30 can be set to screen shells with a thickness of 5cm. Thus, shells with a thickness greater than 8cm are sorted by the first sorting mechanism 30, while shells with a thickness less than 8cm but greater than 5cm are sorted by the second sorting mechanism 30.

[0031] The sorting device 100 provided in the above embodiment includes a guide conveying plate 25, a drive shaft 22, and a chain 24 arranged by a shell conveying mechanism 20. A pusher block 241 is provided on the side of the chain 24 near the guide conveying plate 25. When the drive shaft 22 drives the chain 24 to rotate, it drives the pusher block 241 to move along the first direction A and push the shells on the guide conveying plate 25. Then, a sorting mechanism 30 is provided through the notch 251 opened in the guide conveying plate 25. The sorting mechanism 30 includes a housing 31 and a thickness sorting component 32 disposed in the housing 31. The housing 31 is provided with a through cavity 311 for shells to pass through and a guide channel 312 for collecting the sorted shells. In the cavity 311, the bottom surface of the cavity 311 is coplanar with the top surface of the guide conveyor plate 25. The housing 31 is rotatably connected to the bottom surface of the cavity 311 with a hinged plate 314. A portion of the thickness sorting component 32 forms a shell screening area with the guide conveyor plate 25. When shells that meet the thickness requirements are pushed into the cavity 311, the thickness sorting component 32 controls the rotation of the hinged plate 314 to connect the cavity 311 with the guide channel 312, so that the shells that meet the thickness requirements are screened and fall into the guide channel 312, completing the screening. At the same time, multiple sorting mechanisms 30 can be set on the guide conveyor plate 25 along the first direction A to achieve precise sorting of shells of different thicknesses at the same time.

[0032] Please see Figure 3 In some embodiments, the top surface of the guide conveyor plate 25 is provided with at least two limiting plates 26 spaced apart along the second direction B. Each limiting plate 26 is arranged along the length direction of the guide conveyor plate 25, that is, a conveying channel for adjusting and limiting the shell is formed between two adjacent limiting plates 26. The two limiting plates 26 are located between the guide conveyor plate 25 and the push block 241 in the third direction C. One end of each limiting plate 26 is provided with a bent section 261. A flared section 2611 is provided on the guide conveyor plate 25 at the initial end where the shell is placed, forming a conveying channel between two bent sections 261. When the shell is placed in the flared section 2611, the push block 241 drives the shell to move. Since the width of the conveying channel formed by the two limiting plates 26 in the rear section of the flared section 2611 is smaller than that of the flared section 2611, when the shell moves backward from the flared section 2611, the shell is uniformly adjusted to move in one direction, which facilitates the sorting mechanism 30 to sort the shell.

[0033] Please see Figure 5 and Figure 6In some embodiments, the bottom of the sorting adjustment box 321 is provided with a limiting groove 3211 opening towards the guide conveyor plate 25. A nut 3212 is provided at the bottom of the limiting groove 3211. A portion of the sorting plate 323 extends into the limiting groove 3211 and is provided with an adjusting bolt 3231 threadedly connected to the nut 3212. The adjusting bolt 3231 is configured to adjust the relative distance between the sorting plate 323 and the guide conveyor plate 25. The transmission member 322 has an inclined surface 32211 on the side near the sorting adjustment box 321, and a part of the sorting adjustment box 321 abuts against the inclined surface 32211 on one side. When the sorting adjustment box 321 slides upward along the third direction C, the roller 3213 of 211 presses the inclined surface 32211 to push the transmission member 322 to slide along the first direction A. The hinge plate 314 is provided with a slot 3141 and an arc-shaped surface 3142 near the slot 3141 at the end opposite to the box body 31. The transmission member 322 extends to the end near the hinge plate 314 and is provided with a locking part. The locking part is rotatably connected to a roller 32221 that is adapted to the arc-shaped surface 3142. The locking part is configured to be able to slide selectively along the first direction A to extend into or out of the slot 3141, thereby locking or releasing the hinge plate 314.

[0034] Specifically, the sorting adjustment box 321 is slidably connected to the opening at the bottom of the limiting cavity 313 to achieve a slidable connection with the housing 31. Simultaneously, a first elastic element 3214, arranged along a third direction C, is provided on the top of the sorting adjustment box 321. The first elastic element 3214 can be a spring structure, and its top end is fixedly connected to the limiting cavity 313. The first elastic element 3214 allows the sorting adjustment box 321 to reset after moving upwards. The adjusting bolt 3231 passes through the nut 32 from above the housing 31. 12 is fixedly connected to a part of the sorting plate 323. When it is necessary to screen shells of different thicknesses, the sorting plate 323 is slid upward along the third direction C by rotating the adjusting bolt 3231, thereby adjusting the height of the shell sorting area formed between the sorting plate 323 and the guide conveyor plate 25. At the same time, this adjustment process does not change the relative position between the sorting adjustment box 321 and the box 31, so that the connection between the sorting adjustment box 321 and the transmission component 322 is not affected after adjustment, thus ensuring the effective sorting of shells.

[0035] Please see Figure 5 and Figure 6Optionally, the limiting cavity 313 is arranged along the first direction A. The transmission member 322 includes a first end 3221 extending near the sorting adjustment box 321 and a second end 3222 extending away from the first end 3221 and near the hinge plate 314. The first end 3221 and the second end 3222 are integrally formed. The first end 3221 can be a slider whose upper and lower surfaces respectively abut against the upper and lower surfaces of the limiting cavity 313. The end face of the slider near the sorting adjustment box 321 is set as an inclined surface 32211. A roller 3213 is provided on one side of the sorting adjustment box 321 to abut against the inclined surface 32211. At the same time, the first end 3221 is slidably connected to the top surface of the limiting cavity 313, so that the transmission member 322 can only slide in the first direction A. The first end 3221 is provided with a second elastic element 3223 on the side face away from the sorting adjustment box 321, which is connected to the side surface of the limiting cavity 313. The second elastic element 3223 can be a spring structure. The second elastic element 3223 enables the transmission element 322 to automatically reset after sliding along the first direction A. The second end 3222 is slidably connected to the top surface of the guide channel 312 in the first direction A. That is, when the first end 3221 slides, the second end 3222 slides synchronously. The second end 3222 extends to the vicinity of the hinge plate 314 and is slidably connected to the top surface of the guide channel 312. At the same time, the second end 3222 is provided with a snap-fit ​​part, which is rotatably connected to a roller 32221 that is adapted to the arc surface 3142.

[0036] During the sorting process, when the shells pass between the sorting plate 323 and the guide conveyor plate 25, since the guide conveyor plate 25 is fixed, it squeezes the sorting plate 323, causing the sorting plate 323 and the sorting adjustment box 321 to slide together along the third direction C. As a result, the roller 3213 squeezes and slides along the inclined surface 32211. Since the transmission member 322 and the top surface of the limiting cavity 313 are slidably connected in the first direction A, the transmission member 322 slides to the left along the first direction A under the influence of the squeezing force. As a result, the snap-fit ​​part provided at the second end 3222 separates from the snap-fit ​​groove 3141 provided at the hinge plate 314. Under the influence of gravity, the hinge plate 314 rotates downward, thereby connecting the through cavity 311 with the guide channel 312. When the shells move to the hinge, they fall into the guide channel 312 and fall out from the side end face of the sorting device 100 along the guide channel 312 for collection.

[0037] Meanwhile, the hinge plate 314 has an arc-shaped surface 3142 at the top of one end of the slot 3141, and a roller 32221 adapted to the arc-shaped surface 3142 is provided at the first end 3221. When the hinge plate 314 rotates upward to reset, the roller 32221 can slide into the slot 3141 along the arc-shaped surface 3142, realizing the engagement of the locking part with the slot 3141. That is, the setting of the roller 32221 and the arc-shaped surface 3142 reduces the friction during the reset process of the hinge plate 314.

[0038] Continue reading Figure 5 Optionally, in order to limit the downward rotation angle of the sorting plate 323 and the stability after rotation, that is, to prevent the sorting plate 323 from colliding with the corresponding structure and rebounding after downward rotation, a limiting frame 3121 is provided in the guide channel 312. A buffer can be provided on the limiting frame 3121. The buffer can be a cotton layer. Thus, when the sorting plate 323 rotates downward to a certain angle, the limiting frame 3121 provides limiting buffer for the sorting plate 323.

[0039] Please see Figures 6 to 8 In some embodiments, one end of the pivot 3143 of the hinge plate 314 extends to the outside of the housing 31 and is connected to a gear 3144. A rack 242 is provided on the side of the chain 24 near the guide conveyor plate 25, which meshes with the gear 3144. The rack 242 is configured to reset the hinge plate 314 in the open state to lock with the locking part through the gear 3144. The rack 242 has a limiting groove 2421 arranged along the first direction A. A roller assembly 315 adapted to the limiting groove 2421 is provided on the end face of the housing 31 near the gear 3144. The roller assembly 315 is configured to cooperate with the limiting groove 2421 to guide and limit the movement of the rack 242.

[0040] Specifically, the pusher 241 can be mounted on the chain 24 near the cavity 311, while the rack 242 can be mounted on the chain 24 on the other side. The rack 242 is fixed to the chain 24, and multiple racks 242 can be provided, the specific number to be determined based on the sorting mechanism 30. When shells of the preset thickness fall from the opened hinge plate 314 into the guide channel 312, the hinge plate 314 is in the open state. To achieve continuous... The shells are sorted continuously. When the rack 242 slides to one end of the roller assembly 315, as the chain 24 continues to rotate, one end of the roller assembly 315 extends into the limiting through groove 2421, thereby limiting and fixing the rack 242 to ensure that the rack 242 is stably engaged with the gear 3144 when sliding in the first direction A. After the rack 242 engages with the gear 3144, it drives the gear 3144 to rotate, thereby driving the hinge plate 314 to rotate and reset to lock with the locking part.

[0041] Of course, it should be noted that multiple push blocks 241 and racks 242 can be set on the chains 24 on both sides. However, the push blocks 241 and racks 242 must meet the following condition: after the push blocks 241 push the shells to complete the sorting, the racks 242 will mesh with the gears 3144 and drive the hinge plate 314 to rotate and reset. At the same time, the length of the racks 242 must meet the condition that the stroke of the racks 242 after meshing with the gears 3144 is greater than the rotation of the hinge plate 314 to the locking position with the locking part, thereby ensuring the reset of the hinge plate 314.
