Technical Field
[0001] This utility model relates to the field of silkworm cocoon processing technology, specifically a silkworm cocoon sorting machine. Background Technology
[0002] Silkworm cocoons refer to the cocoons of mulberry silkworms. They are the sac-shaped protective layer of silkworms during their pupal stage, containing the pupa. The cocoon layer can be used for silk reeling, and the cocoon shell and waste silk after reeling can be used as raw materials for silk floss and spun silk. During the processing of silkworm cocoons, they need to be sorted and processed by a sorting machine.
[0003] Existing sorting machines sort silkworm cocoons by size by placing them onto a sieve plate inside a vibrating chamber.
[0004] However, when sorting silkworm cocoons, the existing sorting machine has a fixed tilt angle for the sieve plate. If different types of silkworm cocoons fall at different speeds during the sorting process, the cocoons may not be sorted thoroughly, thus reducing the working efficiency of the existing sorting machine.

The second gear, driven by the first gear, causes the studs to move the threaded blocks, thereby causing the inclined columns to rotate the horizontal plate around the rotating shaft, ultimately rotating the screen plate. The driving unit then drives the first gear to rotate.
[0008] Preferably, the drive unit includes a connecting column, which is rotatably connected to the inner wall of the empty box via a bearing, and its end is fixedly connected to the inner wall of the first gear; a handwheel is fixedly connected to the end of the connecting column away from the first gear; wherein, the connecting column is driven to rotate by the handwheel, thereby causing the first gear to rotate.

[0012] This utility model has the following beneficial effects: The silkworm cocoon sorting machine, through the cooperation of the first gear, the second gear, the stud, the threaded block, the inclined column, the column, the rotating shaft, and the drive unit, realizes the adjustment of the angle of the sieve plate. This solves the problem that in existing sorting machines, the sieve plate has a fixed tilt angle, and different types of silkworm cocoons fall at different speeds, which may lead to incomplete sorting of silkworm cocoons and reduce the working efficiency of existing sorting machines.
[0013] By using the combination of the outer shell, ratchet, pawl, second spring, and auxiliary parts, the screen plate after adjustment is limited, which solves the problem that when the screen plate vibrates, the adjustment device will also vibrate slightly, which may cause the adjustment device to rotate and thus change the angle of the screen plate.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] When sorting silkworm cocoons, existing sorting machines have a fixed tilt angle for the sieve plate, and different types of silkworm cocoons fall at different speeds, which may lead to incomplete sorting of silkworm cocoons and reduce the working efficiency of existing sorting machines.
[0021] In view of this, the present invention provides a silkworm cocoon sorting machine. Through the cooperation of a first gear, a second gear, a stud, a threaded block, an inclined column, a vertical column, a rotating shaft, and a drive unit, the angle of the sieve plate can be adjusted. This solves the problem that in existing sorting machines, the sieve plate has a fixed tilt angle, and different types of silkworm cocoons fall at different speeds, which may lead to incomplete sorting of silkworm cocoons and reduce the working efficiency of existing sorting machines.
[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0023] Example 1: By Figure 1-4 It is known that a silkworm cocoon sorting machine includes a vibrating box 1. The top of the vibrating box 1 has a feed inlet. Two screen plates 2 are fixedly connected to the inner wall of the vibrating box 1. The openings on the surfaces of the two screen plates 2 are of different sizes. The operator feeds silkworm cocoons onto the upper screen plate 2 through the feed inlet at the top of the vibrating box 1, causing the cocoons to vibrate. At this time, some cocoons on the upper screen plate 2 fall into the lower screen plate 2, while the remaining cocoons on the upper screen plate 2 fall out of the vibrating box 1 along their surface. Simultaneously, some cocoons on the lower screen plate 2 fall to the bottom of the vibrating box 1, and the remaining cocoons on the lower screen plate 2 fall out of the vibrating box 1 along their surface. Finally, the cocoons at the bottom of the vibrating box 1 also fall out through the opening on the right side of the vibrating box 1, thus greatly improving the sorting of the silkworm cocoons. In the small-scale sorting process, a horizontal plate 4 and a base plate 5 are respectively installed below the vibrating box 1. An empty box 7 is fixedly connected to the surface of the base plate 5. The silkworm cocoon sorting machine also includes an adjustment device 6, a limiting device 8, and a vibration device 3. The adjustment device 6 is located inside the empty box 7; two sets of limiting devices 8 are provided, both located at the bottom of the vibrating box 1; and the vibration device 3 is located below the vibrating box 1. First, the operator adjusts the tilt angle of the sieve plate 2 using the adjustment device 6. After adjustment, the limiting device 8 limits the adjusted sieve plate 2, and the vibration device 3 causes the vibrating box 1 and the sieve plate 2 to vibrate. Specifically, the adjustment device 6 adjusts the angle of the sieve plate 2, the limiting device 8 limits the position of the sieve plate 2, and the vibration device 3 causes the sieve plate 2 to vibrate.
[0024] In the specific implementation process, it is worth noting that the top of the vibrating box 1 has a feed inlet, and there are two screen plates 2. The openings on the surfaces of the two screen plates 2 are not the same size. First, the operator adjusts the tilt angle of the screen plates 2 using the adjusting device 6. After adjustment, the adjusting screen plates 2 are limited by the limiting device 8. The vibrating device 3 makes the vibrating box 1 and the screen plates 2 vibrate. At this time, the operator puts the silkworm cocoons into the upper screen plate 2 through the feed inlet above the vibrating box 1, causing the silkworm cocoons to vibrate. At this time, some of the silkworm cocoons on the upper screen plate 2 will fall into the lower screen plate 2, and the silkworm cocoons remaining on the upper screen plate 2 will fall out of the vibrating box 1 along their surface. At this time, some of the silkworm cocoons on the lower screen plate 2 will fall to the bottom of the vibrating box 1, and the silkworm cocoons remaining on the lower screen plate 2 will fall out of the vibrating box 1 along their surface. Finally, the silkworm cocoons at the bottom of the vibrating box 1 will also fall out through the opening on the right side of the vibrating box 1, thus sorting the silkworm cocoons by size.
[0025] Specifically, firstly, the staff adjusts the tilt angle of the sieve plate 2 using the adjusting device 6. After adjustment, the limiting device 8 limits the adjusted sieve plate 2. The vibrating device 3 vibrates the vibrating box 1 and the sieve plate 2. At this time, the staff puts the silkworm cocoons into the upper sieve plate 2 through the feed inlet above the vibrating box 1, causing the silkworm cocoons to vibrate. At this time, some of the silkworm cocoons on the upper sieve plate 2 will fall into the lower sieve plate 2. The silkworm cocoons remaining on the upper sieve plate 2 will fall out of the vibrating box 1 along their surface. At this time, some of the silkworm cocoons on the lower sieve plate 2 will fall to the bottom of the vibrating box 1. The silkworm cocoons remaining on the lower sieve plate 2 will fall out of the vibrating box 1 along their surface. Finally, the silkworm cocoons at the bottom of the vibrating box 1 will also fall out through the opening on the right side of the vibrating box 1, thus sorting the silkworm cocoons by size.
[0026] Example 2: From Figure 1-4It can be seen that the adjusting device 6 includes a first gear 61, a second gear 62, studs 63, threaded blocks 64, inclined columns 65, columns 66, a rotating shaft 67, and a driving unit 68. The first gear 61 is located inside the empty box 7; there are two second gears 62, both meshing with the two sides of the first gear 61, causing the first gear 61 to rotate, which in turn drives the second gears 62 to rotate; there are two studs 63, both fixedly connected to the inner walls of the two second gears 62, which drive the studs 63 to rotate, and both ends are rotatably connected to the inner wall of the empty box 7 via bearings; there are two threaded blocks 64, both threadedly connected to the outer walls of the two studs 63, which drive the studs 63 to rotate, and both bottoms are slidably engaged with the inner wall of the empty box 7. The two threaded blocks 64 slide in the grooves on the bottom inner wall of the empty box 7, guiding the threaded blocks 64; the inclined column 65 is... There are two columns 65, each rotatably connected to the outer wall of two threaded blocks 64 via pins. The two threaded blocks 64 drive the inclined column 65 to rotate, and the ends away from the two threaded blocks 64 are rotatably connected to the outer wall of the horizontal plate 4 via pins. The two inclined columns 65 drive the horizontal plate 4 to rotate. There are two columns 66, each fixedly connected to the surface of the base plate 5 on the side away from the empty box 7. The rotating shaft 67 is rotatably connected to the inner wall of the two columns 66, and the outer wall is fixedly connected to the inner wall of the horizontal plate 4. The horizontal plate 4 rotates around the rotating shaft 67, thereby driving the vibrating box 1 and the screen plate 2 to rotate. The driving unit 68 is located outside the empty box 7. The second gear 62, driven by the first gear 61, causes the stud 63 to drive the threaded block 64 to move, thereby causing the inclined column 65 to drive the horizontal plate 4 to rotate around the rotating shaft 67, and finally causing the screen plate 2 to rotate. The driving unit 68 drives the first gear 61 to rotate.
[0027] In the specific implementation process, it is worth noting that the first gear 61 rotates, which drives the second gear 62 to rotate. The two second gears 62 drive the studs 63 to rotate, and the two studs 63 drive the threaded blocks 64 to move. The two threaded blocks 64 slide in the grooves on the inner wall of the bottom of the empty box 7, which guides the threaded blocks 64. The two threaded blocks 64 drive the inclined column 65 to rotate, and the two inclined column 65 drive the horizontal plate 4 to rotate. The horizontal plate 4 rotates around the rotating shaft 67 as the center, which in turn drives the vibrating box 1 and the screen plate 2 to rotate, thereby adjusting the tilt angle of the screen plate 2.
[0028] Furthermore, the drive unit 68 includes a connecting column 682 and a handwheel 681. The connecting column 682 is rotatably connected to the inner wall of the empty box 7 via a bearing, and its end is fixedly connected to the inner wall of the first gear 61. The connecting column 682 drives the first gear 61 to rotate. The handwheel 681 is fixedly connected to the end of the connecting column 682 away from the first gear 61. When the operator rotates the handwheel 681, the handwheel 681 drives the connecting column 682 to rotate. In this way, the first gear 61 is rotated by driving the connecting column 682 to rotate through the handwheel 681.
[0029] In the specific implementation process, it is worth noting that when the staff turns the handwheel 681, the handwheel 681 drives the connecting column 682 to rotate, and the connecting column 682 drives the first gear 61 to rotate, thereby driving the first gear 61 to rotate.
[0030] Furthermore, the limiting device 8 includes a housing 81, a ratchet 82, a pawl 83, a second spring 84, and an auxiliary part 85. The housing 81 is fixedly connected to the two columns 66 on opposite sides. The ratchet 82 is fixedly connected to the outer wall of the rotating shaft 67. When the rotating shaft 67 rotates, it drives the ratchet 82 to rotate. The pawl 83 is engaged with the bottom of the ratchet 82, passes through the housing 81, and is movably connected to the housing 81. When adjusting the sieve plate 2, the operator pulls down the pawls 83 on both sides, and the pawls 83 move within the housing 81, disengaging from the ratchet 82. This compresses the second spring 84. The two ends of the second spring 84 are respectively installed on the bottom of the pawl 83 and the outer wall of the housing 81. After the angle of the screen plate 2 is adjusted, the operator releases the pawls 83 on both sides. At this time, the second spring 84 rebounds, and the pawl 83 re-engages with the ratchet 82 through the elastic force. The auxiliary part 85 is set inside the housing 81. The pawl 83 is driven to move in the housing 81 by the rebound of the second spring 84, thereby engaging with the ratchet 82 to limit the adjusted screen plate 2. The auxiliary part 85 fixes the pawl 83.
[0031] In the specific implementation process, it is worth noting that when adjusting the screen plate 2, the operator pulls down the pawls 83 on both sides. The pawls 83 move in the outer casing 81 and disengage from the ratchet 82, thereby compressing the second spring 84. When the rotating shaft 67 rotates, the rotating shaft 67 drives the ratchet 82 to rotate. After the angle of the screen plate 2 is adjusted, the operator releases the pawls 83 on both sides. At this time, the second spring 84 rebounds, and the elastic force makes the pawls 83 re-contact the ratchet 82, thereby limiting the adjustment of the screen plate 2.
[0032] Furthermore, the auxiliary part 85 includes a socket 852, a rod 583, and a third spring 851. The socket 852 is formed on the inner wall of the pawl 83; the rod 583 is inserted into the inner wall of the socket 852. When the pawl 83 moves downward, the operator pulls the rods 583 on both sides, which stretch the third spring 851, causing the rod 583 to leave the socket 852 below the pawl 83. At this time, the operator moves the pawl 83 again, which moves the socket 852, moving the upper socket 852 to the position of the rod 583. Release the insertion rod 583, and the third spring 851 will rebound, allowing the insertion rod 583 to be inserted into the upper insertion hole 852, fixing the position of the pawl 83, and penetrating the outer shell 81 and movably connected to the outer shell 81; the two ends of the third spring 851 are respectively installed at the beginning of the insertion rod 583 and the outer wall of the outer shell 81; after adjustment, the operator repeats the above steps to remove the insertion rod 583 from the upper insertion hole 852 and reinsert it into the lower insertion hole 852. In this case, by moving the insertion rod 583, it is inserted into the corresponding insertion hole 852, fixing the position of the pawl 83.
[0033] In the specific implementation process, it is worth noting that when the pawl 83 moves downward, the operator pulls the two side rods 583. The rods 583 stretch the third spring 851, causing the rods 583 to leave the insertion hole 852 below the pawl 83. At this time, the operator moves the pawl 83 again, causing the insertion hole 852 to move, moving the upper insertion hole 852 to the position of the rod 583. Then, the operator releases the rod 583, and the third spring 851 rebounds, causing the rod 583 to insert into the upper insertion hole 852, fixing the position of the pawl 83 to adjust the angle of the sieve plate 2. After adjustment, the operator repeats the above steps to make the rod 583 leave the upper insertion hole 852 and reinsert it into the lower insertion hole 852, thus fixing the pawl 83.
[0034] Specifically, when adjusting the tilt angle of the sieve plate 2, the operator first pulls the two side rods 583. The rods 583 stretch the third spring 851, causing the rods 583 to leave the insertion hole 852 below the pawl 83. At this time, the operator pulls down the two side pawls 83, causing the pawls 83 to move within the housing 81 and away from the ratchet 82. This compresses the second spring 84, causing the pawls 83 to move the insertion hole 852, moving the upper insertion hole 852 to the position of the rod 583. Then, the operator releases the rod 583, the third spring 851 rebounds, and the rod 583 inserts into the upper insertion hole 852, fixing the position of the pawl 83. Then, the operator rotates the handwheel 681, which rotates the connecting column 682. The first gear 61 is driven to rotate, which in turn drives the second gear 62 to rotate. The two second gears 62 drive the studs 63 to rotate, and the two studs 63 drive the threaded blocks 64 to move. The two threaded blocks 64 slide in the grooves on the inner wall of the bottom of the empty box 7, which guides the threaded blocks 64. The two threaded blocks 64 drive the inclined column 65 to rotate, and the two inclined column 65 drive the horizontal plate 4 to rotate. The horizontal plate 4 rotates around the rotating shaft 67 as the center, which in turn drives the vibrating box 1 and the screen plate 2 to rotate, adjusting the tilt angle of the screen plate 2. After this is completed, the insertion rod 583 is removed from the upper insertion hole 852. At this time, the second spring 84 rebounds, and the elastic force causes the pawl 83 to re-engage with the ratchet 82, and it is reinserted into the lower insertion hole 852 to adjust the tilt angle of the screen plate 2.
[0035] Example 3: From Figure 1 and 2 It can be seen that the vibration device 3 includes a vibration motor 31, a first spring 32, and a telescopic column 33. The model of the vibration motor 31 is selected according to actual needs, as long as it meets the working requirements. The vibration motor 31 is installed at the bottom of the vibration box 1. When the vibration motor 31 is connected to an external power supply, the vibration motor 31 vibrates. The two ends of the first spring 32 are respectively installed at the bottom of the vibration box 1 and the surface of the horizontal plate 4. The vibration box 1 causes the first spring 32 to deform. The two ends of the telescopic column 33 are respectively fixedly connected at the bottom of the vibration box 1 and the surface of the horizontal plate 4. The vibration box 1 causes the telescopic column 33 to reciprocate and extend, thereby causing the vibration box 1 to vibrate up and down, thereby causing the screen plate 2 to vibrate. In this way, the vibration motor 31 causes the vibration box 1 and the screen plate 2 to vibrate, and the vibration box 1 causes the first spring 32 and the telescopic column 33 to move.
[0036] In the specific implementation process, it is worth noting that the model of the vibration motor 31 is selected according to actual needs, as long as it meets the working requirements. When the vibration motor 31 is connected to an external power supply, the vibration motor 31 vibrates, the vibration box 1 causes the first spring 32 to deform, the vibration box 1 causes the telescopic column 33 to reciprocate and extend, thereby causing the vibration box 1 to vibrate up and down, thereby causing the sieve plate 2 to vibrate, thus realizing the sorting of silkworm cocoons.
[0037] Specifically, the vibration motor 31 is connected to an external power supply. The vibration motor 31 vibrates, the vibration box 1 causes the first spring 32 to deform, the vibration box 1 causes the telescopic column 33 to reciprocate and extend, thereby causing the vibration box 1 to vibrate up and down, thereby causing the sieve plate 2 to vibrate and sort the silkworm cocoons. After sorting is completed, the vibration motor 31 is stopped.
