The device comprises two supports and a plurality of spinning beds rotatably arranged between the two supports. The upper and lower surfaces of the spinning beds are wrapped with mesh materials. During the production process of the flat silk, the inclination angle of the flat silk is continuously adjusted, which can not only effectively remove silkworm sand, silkworm urine and diseased silkworms, so that the produced flat silk is uniform and neat, but also can greatly shorten the early wandering time of mature silkworms, shorten the spinning cycle of silkworms on the flat plate, improve the spinning efficiency, and at the same time make the silkworms spin silk more thoroughly, thereby increasing the flat silk yield and reducing the flat silk cost.

Description

Technical Field

[0001] The invention belongs to the technical field of flat wire production, in particular to a production device and a production method for double-sided flat wire. Background Art

[0002] Silkworm cocoons are biological structural materials constructed by silkworm larvae. They are the natural barrier of silkworm pupae, used to resist the natural environment and avoid the invasion of parasites or predators. The special porous hierarchical structure of silkworm cocoons gives them good impact resistance, adsorption capacity, temperature and humidity-related electrical and photoelectric properties, and can be used to make protective materials, adsorption materials, gas filtration materials and biosensors. Improving the microstructure and performance of silkworm cocoons without destroying their unique biological structure has attracted more and more attention to make them better used in composite materials and bionic materials.

[0003] However, the defects of common silk cocoons, such as the single shape, uneven cocoon layer, high porosity, and relatively low mechanical properties, limit the further development and application of silk cocoons. The structure and performance of silk cocoons are affected by many factors, among which the upper cluster environment is the key factor affecting the spinning of silkworm larvae. By changing the cluster tools of silkworms to make silkworms spin in different spaces, silk materials with different shapes or structures can be obtained.

[0004] Flat silk is a kind of silk material with the same structure as cocoons obtained by placing a large number of mature silkworms on a two-dimensional plane to spin silk. Because flat silk is fluffy and soft, can be cut arbitrarily and is easy to make, it is used as a filling material for high-end silk quilts and silk clothes; and flat silk also has the same structure as cocoons, and is an important raw material for preparing lightweight and high-strength composite materials and biomedical materials. However, since the preparation process of flat silk forces silkworms to spin silk on a flat surface, it violates the normal physiological behavior of silkworms spinning silk and making cocoons to a certain extent. Therefore, there are mainly the following problems in the current production of flat silk:

[0005] (1) The bottom layer of silk retains a large amount of silkworm sand and urine, which seriously affects the cleanliness of the silk.

[0006] (2) When silkworms spin silk on a flat surface, it is not conducive to the swinging of their heads and the movement of their bodies. Therefore, the silkworms spin silk on a flat surface for 48-72 hours longer than the normal cocooning time.

[0007] (3) The silk production of silkworms spinning on a flat surface is only about 75% of the normal silk production of cocoons, which will seriously affect the cost of raw materials, resulting in a high market price of the end product;

[0008] (4) Flat silk is produced by the collaborative spinning of many silkworms. If the silkworms are unevenly distributed, the structure of the flat silk will be uneven, which will seriously affect the development and application of high-end products.

[0009] Of course, in response to these problems, some devices and methods specifically used for producing flat silk have emerged in recent years. For example, the invention patent with application number "CN202011189351.3" discloses a flat silk production device and a flat silk production method. The flat silk production device includes a bottom frame, a first side frame and a second side frame respectively connected to the opposite sides of the bottom frame, and a lighting component. A spinning plate parallel to the bottom frame is equidistantly arranged between the first side frame and the second side frame. The spinning plate can be fixed relative to the first side frame and the second side frame or can be tilted relative to the first side frame and the second side frame under force. A cotton yarn net and an absorbent cotton cloth are provided on one side of the spinning plate. When producing flat silk, silkworms spin silk on the cotton yarn net, silkworm sand and urine are absorbed by the absorbent cotton cloth, and the silkworms are irradiated by the lighting component to promote the uniformity of silk spinning by the silkworms.

[0010] Although the technical solution recorded in the invention can reduce the silkworm sand and urine remaining on the flat silk to a certain extent, the effect is not ideal. The obtained flat silk still has silkworm urine spots on the back. At the same time, although light can improve the uniformity of silk spinning to a certain extent, it will also reduce the silk spinning efficiency of silkworms accordingly and increase the production cost of flat silk. In addition, in the production process of flat silk, it is necessary to adjust the angle of the silk-spinning plate. After the angle is adjusted, it is easy for silkworms to hide behind the silk-spinning plate to form cocoons, which will further increase the cost of flat silk production and is not conducive to the acquisition of flat silk. Summary of the invention

[0011] The purpose of the present invention is to provide a production device and a production method for double-sided flat wire to solve the above problems.

[0012] The technical solution adopted by the present invention is as follows:

[0013] A production device for double-sided flat wire comprises two supports and a plurality of spinning beds rotatably arranged between the two supports, wherein both upper and lower surfaces of the spinning beds are wrapped with mesh materials.

[0014] Furthermore, the mesh material is a cotton mesh, a nylon mesh, a plastic mesh or a wire mesh.

[0015] Furthermore, the mesh material has a pore size of 3-5 mm.

[0016] Furthermore, a plurality of first connecting members are arranged on the bracket in the vertical direction, the first connecting members are staggered on both sides of the bracket, second connecting members cooperating with the first connecting members are arranged at both ends of the spinning bed, and adjacent spinning beds are staggered on both sides of the bracket through the first connecting members.

[0017] Furthermore, the first connecting member includes a protrusion connected to the bracket, a clamping slot is arranged on the top of the protrusion, and the second connecting member includes a threaded rod inserted into the clamping slot and rotatably connected to the clamping slot, and the threaded rod is threadedly connected to the clamping member.

[0018] Furthermore, two clamping members are provided, and the two clamping members are respectively located on both sides of the protrusion.

[0019] Furthermore, there are four spinning beds.

[0020] The method for producing flat yarn using the above-mentioned double-sided flat yarn production device comprises the following steps:

[0021] After the silkworms are on the cocoon, they are placed on a flat spinning bed. After they are stable for 1-3 hours, the spinning bed is rotated 50-90 degrees to allow the silkworms to move around and spin silk, and the silkworm sand, silkworm urine and diseased silkworms are automatically removed.

[0022] After the silkworms have been on the cocoon for 8 hours, the silk-spinning bed is rotated again to make it flat until the silk-spinning is completed.

[0023] Preferably, the silk-spinning density of the silkworms is 3-8 jin of mature silkworms / m 2 .

[0024] Preferably, when the silkworms are 5 days old and 7 days old, a certain amount of molting hormone is sprayed on the mulberry leaves to make the silkworms get on the cocoon in an orderly manner.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. Flat yarn can be formed on both sides of the spinning bed. When producing the same output of flat yarn, the volume and floor space of the production device are significantly reduced, thereby effectively increasing the utilization rate of space;

[0027] 2. Flat silk can be formed on both sides of the spinning bed, which is convenient for silkworms to move around and for flat silk production, thus reducing the waste of silk;

[0028] 3. The production device is combined with the production method to obtain uniform flat yarn without increasing the light;

[0029] 4. The production device is combined with the production method, and silkworm sand and urine can be automatically removed without laying absorbent cotton cloth under the spinning bed, so that the obtained flat silk has extremely high cleanliness;

[0030] 5. During the silk-spinning process, by controlling the inclination angle of the spinning bed, the silkworms' wandering time is greatly shortened, the silk-spinning efficiency of the silkworms and the output of flat silk are improved, thereby effectively reducing the production cost of flat silk; BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0039] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0040] The present invention provides a production device for double-sided flat wire, such as Figure 1-4As shown, it includes two brackets 1 and a plurality of spinning beds 2 rotatably arranged between the two brackets 1, that is, the spinning beds 2 can rotate relative to the brackets 1, and the upper and lower surfaces of the spinning beds 2 are wrapped with mesh materials 3, wherein the brackets 1 can stand stably on the ground, mainly playing a supporting role, and the silkworms spin silk on the mesh materials 3 to form flat silk, that is, both sides of each spinning bed 2 can provide silkworms with flat silk. Of course, the number of spinning beds 2 is not fixed, and can be set according to production needs, such as 2, 3, 4, 5, etc.

[0041] Among them, the bracket 1 can be made of hard materials such as wood or stainless steel, and the spinning bed 2 can also be made of hard materials such as wood or stainless steel. For example, the wood can be made into a rectangular frame, and wooden strips can be installed inside the frame for support, and the frame can be wrapped with a mesh material 3. The mesh material 3 can be used as long as it does not cause adverse effects on the silkworms and can be used for the silkworms to climb and spin silk, such as cotton mesh, nylon mesh, plastic mesh, wire mesh, and of course, the mesh aperture is preferably 3-5mm.

[0042] Among them, for the convenience of operation, it is best to connect the silk bed and the bracket 1 in a detachable manner. Rods can be directly set at both ends of the silk-spinning bed 2, and through holes for inserting the rods can be set on the bracket 1. The rods are used to drive the silk-spinning bed 2 to rotate, and nuts are threaded on the rods to limit the position of the rods. However, in this way, in order to ensure that the various positions of the silk-spinning bed 2 do not interfere with each other, a large gap must be left between them in the vertical direction, which will make the overall height of the bracket 1 higher. It is difficult for the breeder to operate the high-rise silk-spinning bed 2, and it is also extremely difficult to disassemble and install any of the silk-spinning beds 2.

[0043] In this regard, a plurality of first connecting members may be arranged on the bracket 1 in the vertical direction, the first connecting members are arranged alternately on both sides of the bracket 1, and second connecting members cooperating with the first connecting members are arranged at both ends of the spinning beds 2, and adjacent spinning beds 2 are alternately installed on both sides of the bracket 1 through the first connecting members. This arrangement can reduce the height of the bracket 1 while ensuring that when the spinning beds 2 are rotated 90° to a vertical state, there is still a relatively loose interval between them, and the mature silkworms on different spinning beds 2 will not interfere with each other.

[0044] As a specific implementation of the first connecting member and the second connecting member, the first connecting member includes a protrusion 4 connected to the bracket 1, and a slot 5 is provided on the top of the protrusion 4. The second connecting member includes a threaded rod 6 that is inserted into the slot 5 and rotatably connected to the slot 5. The threaded rod 6 is threadedly connected with a clamp 7. During installation, the threaded rod 6 is directly inserted into the slot 5 from the top of the slot 5. Since the spinning beds 2 are staggered left and right, the spinning beds 2 will not affect each other when the threaded rod 6 is placed in the slot 5. The slot 5 has no threads. After the threaded rod 6 is placed in the slot 5, it can rotate freely in the slot 5. After the threaded rod 6 is placed in the slot 5, the clamp 7 is screwed until it abuts against the protrusion 4, thereby limiting the position of the threaded rod 6. When the spinning bed 2 needs to be removed, the clamp 7 can be loosened, and the spinning bed 2 can be directly lifted by holding the threaded rod 6, so that the spinning bed 2 can be separated from the slot 5. The operation is extremely simple. Among them, the clamping member 7 can be a nut or a clamping block of any shape, as long as it can be threadedly connected to the threaded rod 6 and its size is larger than the size of the slot 5, and it can limit the position of the threaded rod 6. Of course, it is best to set a clamping member 7 on each side of the slot 5.

[0045] Of course, the first connecting member and the second connecting member may also be in other forms, not necessarily the threaded rod 6 and the slot 5, as long as they can connect the spinning bed 2 and the bracket 1 and enable the spinning bed 2 to rotate 360° relative to the bracket 1.

[0046] In addition, the size of the entire production device is preferably adapted to the height of the breeder so that the breeder can operate it directly. For example, the width of the bracket 1 is set to 7-20 cm and the height is set to 160-230 cm, the length of the spinning bed 2 is set to 100-250 cm and the width is set to 30-150 cm, and the length of the screw is set to 20-30 cm and the diameter is set to 5-10 mm. For production with such a size, it is appropriate to set up 4 spinning beds 2.

[0047] The present invention adopts the following method to produce flat wire using a production device:

[0048] When the silkworms are 5 days old, spray a certain amount of molting hormone on the mulberry leaves to encourage the silkworms to cluster neatly.

[0049] After the silkworms are clustered, they are placed on a flat spinning bed 2. The density of silkworm spinning is 3-8 catties of mature silkworms / m 2 ;

[0050] After the silkworms have been stable for 1-3 hours, rotate the spinning bed 50-90 degrees to make them move and spin silk, and automatically remove excess silkworm feces, silkworm urine and sick silkworms to ensure that the spinning board is clean and tidy. The spinning environment temperature is 24-28℃;

[0051] After the mature silkworms have been clustered for 12-24 hours, the spinning bed 2 is laid flat again to allow it to continue spinning. Generally, the spinning can be completed after 72 hours, and clean and tidy flat silk can be obtained.

[0052] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0053] Example 1

[0054] Assemble the support and spinning bed, and then produce flat wire as follows:

[0055] 1) Raise Liangguang No. 2 silkworms normally, and when the silkworms are 5 days old and 7 days old, spray a certain amount of molting hormone on mulberry leaves to encourage the silkworms to cluster neatly;

[0056] 2) After the silkworms are clustered, they are placed on a horizontal spinning bed 2, and the density of silkworm spinning is 3 jin of mature silkworms / m 2 ;

[0057] 3) After the silkworms have been stable for 1 hour, the spinning bed 2 is rotated 80 degrees to allow the silkworms to wander and spin silk, and the excess silkworm excrement, silkworm urine and diseased silkworms are automatically removed. The spinning environment temperature is 25°C;

[0058] 4) After 12 hours of mature silkworms being clustered, rotate the spinning bed to a horizontal position again to allow it to continue spinning silk, and maintain the spinning temperature at 25°C;

[0059] 5) After 60 hours of cocooning, the spinning bed 2 is rotated by 20°, so that some of the silkworms that have completed spinning can slide into the silkworm receiving tray, and the remaining silkworms that have not completed spinning can continue to spin silk;

[0060] 6) After the silkworms have finished spinning silk for 24 hours, the flat silk is removed as a whole to obtain the flat silk (such as Figure 5 shown).

[0061] Comparative Example 1

[0062] During the flat silk production process, the spinning bed is always kept in a horizontal state, and other operations are the same as in Example 1.

[0063] Comparative Example 2

[0064] A flat yarn production device was manufactured according to the invention patent with application number "CN202011189351.3", and flat yarn was produced in the following manner under the same temperature and humidity conditions as in Example 1:

[0065] 1) Raise Liangguang No. 2 silkworms normally, and spray a certain amount of molting hormone on mulberry leaves when the silkworms are 5 days old;

[0066] 2) placing the mature silkworms after excretion on the spinning board to start spinning silk, and placing 6 jin of mature silkworms per 1.2 square meters;

[0067] 3) The spinning plate is kept in a horizontal state for the first 3 hours, and after 3 hours, the tilt of the spinning plate is adjusted according to the crawling condition of the mature silkworms and the thickness of the silk; and during the spinning process, the LED lamp is turned on and controlled to emit white light and orange-yellow light alternately, and each light color is continuously irradiated for 3-4 hours;

[0068] 4) When the mature silkworms retract their legs and fall off, remove them;

[0069] 5) Place the mature silkworms that have been spinning for 24 hours on the spinning board and let them spin for 3 hours, then remove them after 3 hours;

[0070] 6) Leave the flat silk production device in place for 12 hours and then pick the flat silk.

[0071] Comparative Example 3

[0072] Flat silk was produced in the manner of Example 1, and a lighting plate was added to the spinning device during the production process, and white light and orange-yellow light were alternately irradiated to the mature silkworms at a frequency of 3 hours to obtain flat silk.

[0073] Comparative Example 4

[0074] Normally raised Liangguang No. 2 silkworms were selected and the silkworms were made to spin silk and make cocoons on a normal cluster tool under the same temperature and humidity conditions as in Example 1.

[0075] During the silk-spinning process of silkworms, the silk-spinning time, silk gland residue and pupation rate of Example 1 and Comparative Examples 1-4 were counted, and 15 flat silks produced by Example 1 and Comparative Examples 1-3 were randomly selected, and the silk-spinning amount was quantitatively analyzed, and the flatness, smoothness and cleanliness of the flat silk surface were qualitatively analyzed. The results are shown in Table 1 (the results in Table 1 are all average values):

[0076] Table 1 Analysis of silkworm spinning and flat silk situation

[0077]

[0078] It can be clearly seen from Table 1 that the time from laying on the cocoon to spinning of Example 1 is 72h, which is basically the same as the time of Comparative Example 4, while the time of Comparative Examples 1-3 is significantly extended, indicating that the method of the present invention can effectively improve the production efficiency of flat silk; at the same time, the amount of silk spun by each silkworm in Example 1 is 0.29g, which is basically the same as the amount of silk spun by Comparative Example 4, while Comparative Examples 1-3 are significantly less than Example 1. Relatively speaking, the silk utilization rate of Example 1 is high, which is beneficial to saving production costs, and the pupation rate of Example 1 is also the closest to Comparative Example 4; in addition, the flat silk obtained in Example 1 and Comparative Example 3 has very good cleanliness and almost no silkworm gizzard residue, while the amount of silkworm gizzard residue in Comparative Examples 1 and Comparative Examples 2 is large and the cleanliness is also very poor, indicating that the method of the present invention can produce flat silk with extremely high cleanliness. Figure 5 It can also be clearly seen in.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
