The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

The drying box for the yarn according to the present invention is described below with reference to fig. 1 to 8.

Example 1 as shown in fig. 1 to 3, the drying box for silk threads of the present invention comprises a box body 1, a middle roll shaft 2, a driving assembly and a hot air blower. Openings 12 are formed in the left side wall and the right side wall of the box body 1, the two openings 12 extend in the front-rear direction, the opening 12 in the right side wall of the box body 1 is used for feeding silk threads into the box body 1, and the opening 12 in the left side wall of the box body 1 is used for feeding silk threads out of the box body 1.

The number of the intermediate roll shafts 2 is preferably four in this embodiment, wherein the two intermediate roll shafts 2 on the left side are adjacent to each other, and the two intermediate roll shafts 2 on the right side are adjacent to each other. The intermediate roller shaft 2 includes a plurality of step stub shafts 21 closely distributed in the front-rear direction, the number of step stub shafts 21 being an odd number, and the axis of the step stub shaft 21 extending in the front-rear direction. Among the plurality of step stub shafts 21, the step stub shafts 21 are extended from the center positions of the distribution to the front and rear sides, respectively, and the diameters of the step stub shafts 21 are gradually increased, so that the shape of the intermediate roller shaft 2 is substantially in a honeycomb shape, i.e., the intermediate portion is thin, and the both sides are gradually thicker. The plurality of step short shafts 21 of the intermediate roller shaft 2 are arranged in a stepwise manner in the front-rear direction, and the axes of the plurality of step short shafts 21 are also arranged in a stepwise manner in the front-rear direction. Adjacent stepped stub shafts 21 are connected. Each stepped stub 21 is used to overlap the wire.

The driving assembly is mounted on the case 1 and connected with the plurality of intermediate roll shafts 2 so as to drive the plurality of intermediate roll shafts 2 to rotate synchronously. The air heater is connected with the box body 1 and can input hot air into the box body 1, specifically, the air heater can be placed on the ground together with the box body 1 and then connected with the box body 1 through a pipeline; the air heater can also be directly arranged on the side wall of the box body 1 and communicated with the inner side of the box body 1, and the air heater and the connection form thereof are conventional technology in the field and are not repeated here.

In use, the threads are fed into the box 1 through the opening 12 in the right side wall of the box 1 and are carried on the plurality of intermediate rollers 2. The specific implementation mode of the box body is that a taking and placing opening and a box cover for closing the taking and placing opening can be arranged on the top wall of the box body 1, when the silk thread is carried on the middle roll shaft 2, the box cover can be opened, and a human hand operates the silk thread through the taking and placing opening, so that the silk thread is arranged along the front and rear directions and is placed on the middle roll shaft 2. The wires resting on the intermediate roller shaft 2 are respectively arranged on the respective stepped stub shafts 21, i.e. overlap the respective stepped stub shafts 21, whereby a staggered arrangement of the wires is achieved, after which the wires continue to pass through the opening 12 of the left side wall of the box 1 and are pulled to the left side of the box 1, the portion of the wires located on the left side of the box 1 being reelable on a reel of the outside.

After the silk thread is arranged, the box cover can be closed to be taken and put, in order to ensure the stability of the box cover, the box cover can be detachably arranged on the box body 1, and the specific form of the detachable arrangement is a conventional means in the field and is not repeated here. After that, the drive assembly drives a plurality of middle roller shafts 2 to synchronously rotate, the silk thread is conveyed leftwards by a plurality of middle roller shafts 2, meanwhile, the hot air blower is started and feeds hot air into the box body 1, the silk thread is dried by the hot air, and the silk threads which are arranged in a staggered way due to the action of the step short shaft 21 are staggered by each other, so that the hot air can conveniently pass through, the mobility of the hot air is enhanced, and the uniformity of silk thread drying is improved. In addition, the middle roller shafts 2 staggered up and down enable the silk threads to be arranged in a zigzag shape in the drying box, so that the drying stroke of the silk threads is increased, the silk threads can be conveyed to be proper and fast while the retention time and the drying time are ensured, and the processing efficiency of the silk threads is improved.

Wherein, the first roller 3 extending along the front-rear direction is rotatably installed in the case 1, the first roller 3 is adjacent to the opening 12 of the right side wall of the case 1, and the first roller 3 is positioned at the right side of the four middle rollers 2, and the first roller 3 is used for lapping the wire, specifically, the wire bypasses the first roller 3 from the lower side of the first roller 3. The first motor 31 is installed on the box 1, and the first motor 31 is connected with the first roll shaft 3 to drive the first roll shaft 3 to rotate. The second roller 4 extending along the front-rear direction is rotatably installed in the box 1, the second roller 4 is adjacent to the opening 12 of the left side wall of the box 1, meanwhile, the second roller 4 is located on the left side of the four middle rollers 2, the second roller 4 is used for overlapping wires, specifically, the wires bypass the second roller 4 from the upper side of the second roller 4, a second motor 41 is installed on the box 1, and the second motor 41 is connected with the second roller 4 to drive the second roller 4 to rotate.

When the silk thread is conveyed, the first motor 31 and the second motor 41 can be started simultaneously, and the first roller shaft 3 and the second roller shaft 4 synchronously rotate, so that the silk thread is conveyed and guided, and the silk thread is convenient to enter and exit the box body 1.

Wherein, the step short shaft 21 is sleeved with a sponge sleeve 211, and the silk thread is arranged on the sponge sleeve 211.

The wire is lapped with the stepped short shaft 21 by the sponge cover 211. The sponge sleeve 211 can absorb the moisture on the silk thread in advance, so that the drying time of the silk thread is reduced, and the drying efficiency of the silk thread is further improved.

When the silk thread is conveyed, the external reel also needs to synchronously rotate, so that the winding of the silk thread is realized. However, in winding, since the diameters of the step stubs 21 are different, the feeding capability to the wire is also inconsistent, for example, the feeding amount to the wire is large per one turn of the step stub 21 having a large diameter, and the feeding amount to the wire is small per one turn of the step stub 21 having a small diameter. In other words, the large diameter stepped stub 21 is faster to the wire and the small diameter stepped stub 21 is slower to the wire. The external reels cannot be distinguished due to constant rotation speed, and only the reels can be wound together, so that the wires wound on the reels are disordered and the wires are easy to tear. In order to solve this problem, the present invention also provides embodiment 2.

In embodiment 2, with continued reference to fig. 3 to 6, in the intermediate roller 2, the step stub shaft 21 at the center is set as a center step stub shaft 22, and the step stub shafts 21 are divided into two groups, namely, front and rear, by taking the center step stub shaft 22 as a boundary, it is understood that the center step stub shaft 22 is not included in the two groups of step stub shafts 21, and the intermediate roller 2 further includes two supporting members corresponding to the two groups of step stub shafts 21, respectively, the supporting members including a supporting shaft 23, a supporting disk 24, and a transmission shaft 25.

The inside of the step short shaft 21 is hollow, the axial direction of the supporting shaft 23 is consistent with the front-back direction, the supporting shaft 23 sequentially passes through the step short shafts 21 of the corresponding group along the front-back direction and extends to the center step short shaft 22, and the supporting shaft 23 is connected with the box body 1. Both end walls of the step stub shafts 21 of the corresponding group are provided with circular grooves which are coaxial with the step stub shafts 21 and are adjacent to the peripheral wall of the step stub shaft 21, whereby the circular grooves of the step stub shafts 21 in each group are also distributed stepwise in the front-rear direction, and the diameters of the circular grooves are proportional to the diameters of the step stub shafts 21, i.e., the diameters of the circular grooves of the step stub shafts 21 having a larger diameter are also larger, and the diameters of the circular grooves of the step stub shafts 21 having a smaller diameter are also smaller. It will be appreciated that the support shaft 23 passes through a plurality of circular slots. The number of the supporting plates 24 is equal to that of the round grooves and corresponds to one another, the supporting plates 24 and the corresponding round grooves are coaxial, the supporting plates 24 are arranged on the inner sides of the corresponding round grooves and fixed on the supporting shafts 23, and the two supporting plates 24 can be integrally formed in the middle area of the two adjacent step short shafts 21. The peripheral wall of the circular groove is provided with a coaxial ring gear structure 212, which ring gear structure 212 is integrally formed with the stepped stub shaft 21. The stepped stub shafts 21 are mounted on respective support plates 24 by a gear ring structure 212.

The bottom of the supporting disk 24 is provided with notches, the transmission shaft 25 extends along the front-rear direction and sequentially passes through the notches, the transmission shaft 25 is provided with gear structures 251 which are equal to the gear ring structures 212 in number and correspond to each other one by one, the gear structures 251 are coaxial with the transmission shaft 25, the sizes and the teeth numbers of the gear structures 251 are consistent, the gear structures 251 are meshed with the corresponding gear ring structures 212, and the two gear structures 251 at the middle areas of the two adjacent step short shafts 21 can be integrally formed. The transmission shafts 25 and the central step short shaft 22 are coaxial, the first ends of the transmission shafts 25 are fixedly connected with the central step short shaft 22, the second ends of the transmission shafts 25 are rotatably mounted on the box body 1, the second ends of each transmission shaft 25 are connected with a driving assembly, and the driving assembly can drive all the transmission shafts 25 to synchronously rotate.

When the driving assembly drives all the driving shafts 25 to synchronously rotate, the driving shafts 25 drive the gear structures 251 on the driving shafts to rotate, the gear structures 251 drive the corresponding step short shafts 21 to rotate through the corresponding gear ring structures 212, and meanwhile, the driving shafts 25 drive the center step short shafts 22 to rotate. So far, the effect of simultaneous rotation of all the step stubs 21 is achieved. At this time, since the diameters of the respective ring gear structures 212 are not uniform, the gear ratio with respect to the gear structure 251 is also different, that is, the gear ratio of the ring gear structure 212 of the stepped stub shaft 21 having a larger diameter is also larger, the stepped stub shaft 21 is relatively slower in rotation, the gear ratio of the ring gear structure 212 of the stepped stub shaft 21 having a smaller diameter is also smaller, and the stepped stub shaft 21 is relatively faster in rotation. The design makes the rotating speed of the step short shaft 21 and the structure of the step short shaft complementary, thereby ensuring that the quantity of the silk threads on each step short shaft 21 to be conveyed in unit time is consistent, in other words, the conveying speed of the silk threads on each step short shaft 21 is unified, the unified winding of an external reel is convenient, the occurrence of uneven phenomenon during winding is avoided, and meanwhile, the regular conveying and winding mode also avoids the tearing of the silk threads. Furthermore, the support plate 24 is used to carry the weight of the stepped stub shaft 21.

Example 3 is also provided in order to accelerate the evaporation of moisture from the sponge cover 211.

In example 3, with continued reference to fig. 4 to 8, in the intermediate roll shaft 2, a support plate 24 having a larger diameter can cover the end face of the sponge sleeve 211 of the other, and the support plate 24 is provided with a suction opening 241, wherein the suction opening 241 communicates with the sponge sleeve 211 of the other, specifically, the suction opening 241 communicates with the end face of the sponge sleeve 211 of the small-diameter step short shaft 21 of the two adjacent step short shafts 21, and the suction opening 241 also communicates with the hollow region inside the large-diameter step short shaft 21.

The interlayer chamber 13 communicates with the hollow region of the stepped stub shaft 21 located at the forefront side through the vent and gas-passing port 242. The front side wall of the case 1 is provided with an exhaust fan 5 or an air pump which is communicated with the interlayer chamber 13, and in this embodiment, the exhaust fan 5 is preferably used, and the exhaust fan 5 is specifically located at the front side of the case 1.

In addition, the plate surface of the circular plate 111 near the forefront step short shaft 21 is provided with an air suction inlet 1115, the air suction inlet 1115 is communicated with the end surface of the sponge sleeve 211 on the forefront step short shaft 21, and the air suction inlet 1115 is also communicated with the circular cavity 1112.

The air heater can start the exhaust fan 5 when drying the silk thread, and the hot air in the box body 1 is sucked into the hollow area inside the stepped short shaft 21 through the exhaust port 241 by the sponge sleeve 211. Then, the hot air is collected into the circular plate 111 through the notch of the support plate 24. The hot air then flows into circular chamber 1112 through air passage 242 and second air passage 1114, stays in circular chamber 1112 for a short period of time, and flows into interlayer chamber 13 through first air passage and tip 1113.
