Description

Technical Field

[0001] The invention belongs to the technical field of silk cocoon cooking, and in particular relates to a cocoon cooking device for silk production. Background Art

[0002] Cocoon boiling is a crucial step in the silk production process. Using water and heat, the sericin surrounding the cocoons is appropriately swelled and softened, reducing the adhesive force between the silk strands to a lesser degree than their wet strength, allowing them to be continuously and sequentially separated during reeling. For example, a cocoon boiling device for silk quilt production, published as CN217351631U, includes a boiling box connected to a threaded rod via a drive assembly. A first sliding block is threadedly connected to the rod, and a filter is fixedly connected to the sidewall of the first sliding block. The drive assembly includes a drive chamber defined within the inner wall of the boiling box, a servo motor mounted within the inner wall of the drive chamber, a drive shaft provided at the output end of the servo motor, a linkage gear fixedly connected to the end of the drive shaft, and a fixed gear meshing with the linkage gear. The utility model is provided with a filter screen and a driving assembly. After the silk cocoons are placed in the cooking box for cooking, the driving assembly drives the first sliding block, so that the first sliding block can drive the filter screen to slide upward, so that the filter screen drives the silk cocoons to the top of the cooking box, and the cooked silk cocoons can be quickly taken out of the cooking box, and the material discharge is completed quickly.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figure 1-Figure 4The present invention provides a technical solution: a cocoon boiling device for silk production, comprising a cocoon boiling box 1, a driving member 5 is provided at the bottom of the cocoon boiling box 1, and the driving member 5 can drive two driving screw rods 51 to rotate. The driving member 5 includes a driving screw rod 51 vertically installed on the inner side walls of the two ends of the cocoon boiling box 1, and a lifting filter screen 3 is horizontally and movably provided between the two driving screw rods 51. Subsequent rotation of the driving screw rod 51 can drive the lifting filter screen 3 to move upward, driving the cocoons in the cocoon boiling box 1 to move upward and float to the water surface. A stirring and discharging mechanism 2 is horizontally provided between the two driving screw rods 51 and located above the lifting filter screen 3. The stirring and discharging mechanism 2 can automatically stir and discharge the cocoons that float to the water surface and remain on the lifting filter screen 3. In the stirring and discharging process, there is no situation that the cocoons are touched by humans, thereby increasing the safety of automatic cocoon discharging and improving the discharging efficiency. In addition, the cocoon stirring net 22 can stir the cocoons during the cocoon boiling process. Stirring increases the completeness of cocoon cooking and heating. The stirring and unloading mechanism 2 includes a mounting shaft 21. A plurality of cocoon stirring nets 22 are evenly arranged on the circumferential surface of the mounting shaft 21. When the cocoon stirring net 22 is located in the cocoon cooking box 1, the cocoons in the cocoon cooking box 1 can be stirred to allow the cocoons to be fully heated and cooked. The outer end of the cocoon stirring net 22 is provided with an elastic pushing strip 24 extending to the surface of the stirring and unloading mechanism 2. The elastic pushing strip 24 is bendable and has an elastic recovery effect, which facilitates the elastic pushing strip 24 to contact the upper surface of the lifting filter 3. A driving motor 23 is provided at the right end of the mounting shaft 21. The driving motor 23 is a waterproof motor. The driving motor 23 can drive the mounting shaft 21 to rotate. At the same time, a protective shell can be added to the outer side of the driving motor 23 when it is installed and used. The driving motor 23 and the driving screw rod 51 are movably connected through the provided lifting component 25. The lifting component 25 can drive the driving motor 23 and the mounting shaft 21 to rise and fall;

[0029] The cocoon stirring net 22 includes a vertical stirring net fixed to the circumferential surface of the mounting shaft 21, and a lateral stirring net is obliquely provided at the outer end of the vertical stirring net. The lateral stirring net forms an angle with the vertical stirring net. As the cocoon stirring net 22 rotates, the cocoons that have emerged from the water surface can be moved into the water, allowing the cocoons to be continuously sunk into the water, thereby increasing the thoroughness of the cocoons being heated and cooked.

[0030] The lifting component 25 includes a driving nut block 252 that is screwed onto the driving screw rod 51. As the driving screw rod 51 rotates, the driving nut block 252 and the mounting shaft 21 can move upward or downward. A lifting plate 251 is provided at the right end of the driving motor 23. The lifting plate 251 can drive the driving motor 23 to move. The lifting plate 251 is located above the driving nut block 252 and the two are elastically connected. The elastic connection effect can allow the lifting plate 251 to move downward for a distance, thereby allowing the components installed on the lifting plate 251 to move downward for a distance, making it convenient for the cocoon to move the net 22 close to the surface of the lifting filter 3.

[0031] In this embodiment, preferably, a fixing column 253 is vertically provided on the upper surface of the driving nut block 252, and the upper end thereof passes through the lifting plate 251. An elastic member 254 is sleeved on the fixing column 253. The elastic member 254 can be a spring. When the lifting plate 251 is restricted from moving downward, the elastic member 254 can be compressed. The upper and lower ends of the elastic member 254 are respectively fixed to the lower surface of the lifting plate 251 and the upper surface of the driving nut block 252.

[0032] In this embodiment, preferably, rectangular notches are provided at both ends of the lifting filter 3, and a rotating nut block 31 is rotatably provided in the rectangular notch. The two are rotatably connected to facilitate the backward rotation of the lifting filter 3, so that the lifting filter 3 forms a certain angle with the vertical direction, which is convenient for the silkworm cocoons to be unloaded from the lifting filter 3. The rotating nut block 31 is threadedly sleeved on the driving screw 51, and the rotating nut block 31 rises and falls as the driving screw 51 rotates.

[0033] In this embodiment, preferably, a fixed convex plate 256 is provided on the upper surface of the lifting filter 3 and is located on the rear side of the driving screw 51. A rectangular hole is provided on the surface of the fixed convex plate 256. A support rod 255 is provided on the rear surface of the lifting plate 251. The lower end of the support rod 255 extends to the inner side of the fixed convex plate 256 and the two are rotatably connected. As the lifting plate 251 moves downward, the support rod 255 can be driven to move downward and the lifting filter 3 can be rotated downward. The support rod 255 is rotatably connected to the rectangular hole, which is convenient for adapting to the rotation of the lifting filter 3.

[0034] In summary, when in use, the cocoons are heated and boiled in the cocoon boiling box 1. At the same time, the driving motor 23 works, driving the mounting shaft 21 to rotate, and the cocoon stirring net 22 on the mounting shaft 21 rotates, stirring the cocoons in the cocoon boiling box 1, and the lateral stirring net at the upper end of the cocoon stirring net 22 rotates. As the lateral stirring net rotates, the cocoons floating on the water surface are pressed into the water to fully heat and boil the cocoons. After the cocoon boiling time is reached, the working motor 52 works, and the linkage belt and pulley are used to make the two driving screws 51 rotate synchronously, driving the driving nut block 252 and the rotating nut The block 31 moves upward, causing the stirring and unloading mechanism 2 and the lifting filter 3 to move upward synchronously. After the lifting filter 3 is released from the water surface, the cocoons are retained on the lifting filter 3. At this time, the lifting plate 251 contacts the free end of the extension limit rod 63. As the lifting plate 251 continues to move upward, the lifting plate 251 is limited by the extension limit rod 63, causing the lifting plate 251 to move downward along the fixed column 253. The elastic member 254 is compressed, and the support rod 255 moves downward with the lifting plate 251. The support rod 255 pushes the lifting filter 3 to rotate backward, allowing the lifting filter 3 to rotate backward. 3 forms a certain angle with the vertical plane. After the lifting plate 251 moves down to a certain distance, the upper driving gear 261 meshes with the lower driven gear 263. At this time, the working motor 52 stops working, the driving screw 51 stops rotating, and the height position of the lifting filter 3 and the stirring and unloading mechanism 2 is limited and fixed. As the driving motor 23 continues to work, the installation shaft 21 and the cocoon stirring net 22 continue to rotate, the upper driving gear 261 meshes with the lower driven gear 263 to drive the storage shaft 264 to rotate, so that the pushing belt 265 is wound. As the pushing belt 265 shortens, it drives the pushing material. The plate 27 and the elastic material strip 28 move backward to push the cocoons on the upper surface of the lifting filter 3 toward the cocoon moving net 22, so that the cocoon moving net 22 rotates to move the cocoons on the lifting filter 3 backward and fall on the guide member 4 for loading and unloading. During the whole process, the cocoons on the lifting filter 3 are continuously moved and unloaded, which reduces the trouble of manually removing the cocoons, and also avoids the situation of accidentally injuring the cocoons by touching the high-temperature cocoons, thereby improving the safety of cocoon steaming and heating and improving the efficiency of cocoon steaming and unloading. At the same time, the cocoons can be pressed into the water for stirring, which increases the sufficiency and uniformity of the heating of the cocoons.

[0035] Example 2

[0036] Reference Figure 5 and Figure 6 , which is the second embodiment of the present invention, and the difference between this embodiment and the previous embodiment is.

[0037] In this embodiment, preferably, a pushing plate 27 is horizontally provided on the upper surface of the front end of the lifting filter 3, and an elastic material strip 28 is provided on the lower surface of the pushing plate 27. The elastic material strip 28 can facilitate the cocoons on the lifting filter 3 to push the material backward. A pushing member 26 is provided between the pushing plate 27 and the driving motor 23. The pushing member 26 includes an output shaft 262 provided between the inner end of the driving motor 23 and the mounting shaft 21. An upper driving gear 261 is sleeved on the output shaft 262. A vertical plate is provided on the lower surface of the driving nut block 252, which can support and install the storage shaft 264. A storage shaft 264 is rotatably provided on the inner side of the vertical plate. A lower driven gear 263 located below the upper driving gear 261 is sleeved on the storage shaft 264. 3 is engaged with the upper driving gear 261, which can shorten the length of the pushing belt 265. A guide roller 266 is provided on the upper surface of the lifting filter 3 and is located below the storage shaft 264. A pushing belt 265 is wound around the storage shaft 264. The other end of the pushing belt 265 passes through the guide roller 266 and is fixed to the upper surface of the pushing plate 27. The change in the length of the pushing belt 265 can drive the pushing plate 27 to move. At the same time, a spring is provided between the two ends of the pushing plate 27 and the inner surface of the cocoon boiling box 1, which can facilitate the subsequent disengagement of the two gears. The spring drives the pushing plate 27 to move forward and reset. A T-slot is provided on the upper surface of the outer frame of the lifting filter 3, and a slider extending into the T-slot is provided on the lower surface of the pushing plate 27 to limit and guide the moving direction of the pushing plate 27.

[0038] In this embodiment, preferably, limiting components 6 are provided on both sides of the cocoon boiling box 1. The limiting components 6 can be used to allow the lifting plate 251 to move downward, thereby driving the cocoon prying net 22 to move downward close to the surface of the lifting filter 3. The limiting components 6 include a mounting horizontal plate 61 vertically fixed to the side of the cocoon boiling box 1. Two fixed tubes 62 are vertically fixed to the upper surface of the mounting horizontal plate 61. An extended limiting rod 63 is provided inside the fixed tube 62. The extended limiting rod 63 can move up and down to change the distance between it and the fixed tube 62, and a limiting bolt 64 is provided between the two. The limiting bolt 64 can limit and fix the height position of the extended limiting rod 63. The other end of the extended limiting rod 63 extends to above the lifting plate 251, so that the extended limiting rod 63 can contact the lifting plate 251 conveniently.

[0039] When the lifting plate 251 contacts the free end of the extension limit rod 63, the lifting plate 251 is pushed downward by the extension limit rod 63, driving the upper driving motor 23 and the output shaft 262 to move downward, so that the upper driving gear 261 is meshed with the lower driven gear 263. The meshing of the two drives the storage shaft 264 to rotate, the winding length of the pushing belt 265 is shortened, and the pushing plate 27 moves backward. The mainspring is compressed, and the pushing plate 27 drives the elastic material strip 28 to push the cocoon backward. After the cocoon is pushed and discharged by the cocoon-pushing net 22, the driving screw 51 rotates in the opposite direction, driving the stirring and discharging mechanism 2 to move downward without the restriction of the extension limit rod 63. The lifting plate 251 is reset upward under the drive of the elastic member 254, the upper driving gear 261 is disengaged from the lower driven gear 263, and the pushing plate 27 moves forward and resets under the drive of the mainspring. The whole process facilitates the pushing and discharging of the cocoons, thereby increasing the efficiency of cocoon steaming and discharging.

[0040] Example 3

[0041] Reference Figure 7 , which is the third embodiment of the present invention, and the difference between this embodiment and the above two embodiments is.

[0042] In this embodiment, preferably, a guide member 4 is provided on the rear surface of the cocoon boiling box 1, and the guide member 4 includes a frame plate 42 provided on the rear surface of the cocoon boiling box 1, and a feed belt 43 is rotatably provided inside the frame plate 42. The surface of the feed belt 43 is distributed with filter holes, which can facilitate the falling of cleaning water, and a collecting box for collecting water flow can be provided below the feed belt 43 in the outside world, and a plurality of conveying rollers are rotatably provided inside the frame plate 42. The feed belt 43 is sleeved on the plurality of conveying rollers, and the ends of the plurality of conveying rollers are linked by chains and sprockets, and a motor is provided at the end of the rearmost conveying roller, and a distribution pipe 44 is provided at the front end of the frame plate 42 horizontally above the feed belt 43, and a water tank 41 is provided on the left side of the cocoon boiling box 1, and a water pump 47 is provided on the upper surface of the water tank 41. The water pump 47 can pump water out of the water tank 41 and send it into the distribution pipe 44.

[0043] In this embodiment, preferably, a water supply pipe 46 is provided between the water pump 47 and the distribution pipe 44, and cleaning nozzles 45 are distributed along the length direction of the lower surface of the distribution pipe 44. The multiple cleaning nozzles 45 spray water synchronously to form a water curtain for cleaning the cocoons. The driving component 5 also includes a working motor 52 installed under the driving screw 51 on the left side, and a linkage belt is provided between the two driving screws 51. At the same time, a pulley is provided at the lower end of the two driving screws 51, and a linkage belt is provided between the two pulleys to realize the synchronous rotation of the two driving screws 51.

[0044] In summary, when in use, the cocoons discharged from the cocoon-moving net 22 fall on the feed belt 43, and the feed belt 43 moves backward to guide the material. The water pump 47 works to pump the water in the water tank 41 into the water supply pipe 46, and flows into the distribution pipe 44. It is sprayed out through multiple cleaning nozzles 45 on the lower surface of the distribution pipe 44 to form a water curtain, and acts on the cocoons on the feed belt 43 for cleaning, reducing impurities on the surface of the cocoons and increasing the cleanliness of the cocoons. The cleaned water falls downward through the filter holes on the surface of the feed belt 43 into a collection box set outside, increasing the convenience and efficiency of heating and steaming the cocoons.

[0045] Example 4

[0046] This embodiment is obtained by combining Example 1, Example 2 and Example 3.

[0047] During use, the cocoons are heated and cooked in the cocoon cooking box 1. After cooking, the driving component 5 is used to drive the driving screw 51 to rotate, so that the stirring and unloading mechanism 2 and the lifting filter 3 move upward synchronously. When they move to a suitable height, the lifting component 25 restricted by the limiting component 6 works, driving the mounting shaft 21 and the cocoon moving net 22 to move downward, and the pushing component 26 pushes the cocoons backward, while the cocoon moving net 22 moves the cocoons backward and drops them into the guide component 4 for guiding and cleaning. The whole process increases the safety of cocoon cooking and unloading and improves the efficiency of cocoon cooking and unloading.
