Description

Technical Field

[0001] The present invention relates to the technical field of cable drying, and in particular to a cable drying device and method for cable production. Background Art

[0002] Cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. During the production process, after the outer skin is cast by an extruder, the cable is usually immersed in cold water for rapid cooling. After cooling, there will be a certain amount of water droplets on the surface of the cable. The cable needs to be dried to ensure the subsequent processing and preservation of the cable.

[0003] In existing cable drying devices, two groups of absorbent cotton are usually used to absorb water droplets on the cable surface in turn, and then the cable is dried by hot air. However, there is a problem in this process: when one group of absorbent cotton reaches saturation and needs to be replaced, it is usually necessary to use hot air circulation in the drying box for drying. However, due to the large amount of water absorbed by the absorbent cotton, the efficiency of hot air drying is relatively low, which often results in the previous group of absorbent cotton not being completely dried when the other group of absorbent cotton also reaches saturation. This situation will affect the drying effect and drying efficiency of the cable. Summary of the invention

[0021] As a preferred embodiment of the cable drying device for cable production described in the present invention, the drainage component includes a first drainage pipe fixedly connected to the bottom of two square tubes respectively, the bottom end of the first drainage pipe extends out of the drying box and is fixedly connected to the same U-shaped tube, the bottom end of the U-shaped tube is fixedly connected to a second drainage pipe, and a valve is installed on the second drainage pipe.

[0022] The drying method using the above cable drying device for cable production comprises the following steps:

[0023] Step 1: In the initial state, a pair of semicircular plates in the two square tubes are in the closed and open states respectively. The cable to be dried enters the drying box through the inlet hole, then absorbs water droplets through a pair of square tubes, and finally passes through the drying unit and out of the outlet hole to complete the drying process;

[0024] Step 2: When the cable passes through the square tube, the absorbent cotton strips on the closed pair of semicircular plates absorb the water drops on the cable. After a period of time, the absorbent cotton blocks on the closed pair of semicircular plates are saturated with water. Then, the driving motor is started. The driving motor causes the closed pair of semicircular plates to open and squeeze the absorbent cotton blocks saturated with water to squeeze out the water and speed up the drying efficiency of the absorbent cotton blocks. At the same time, the other pair of opened semicircular plates is closed to absorb water. The specific process is: the driving motor drives the forward and reverse screw rods to rotate. When the forward and reverse screw rods are running, a pair of L-shaped rods threadedly connected thereto approach or move away from each other, and a pair of L-shaped rods drive another pair of L-shaped rods to move away from or approach each other through the first synchronization rod and the second synchronization rod.

[0025] Step 3: When the pair of closed semicircular plates are opened by the L-shaped rod, the first gear is separated from the second convex tooth before opening, while the second gear is meshed and connected with the first convex tooth, and the limit plug rod is adapted to slide with the limit plug hole; when the L-shaped rod drives the vertical rod to move in the direction away from the semicircular plate, the vertical rod pulls the push-pull rod to drive the semicircular plate to retreat under the limiting action of the limiting plate and the inner wall of the moving groove, and the semicircular plate drives the absorbent cotton block to retreat. During the retreat process, the absorbent cotton block contacts the arc-shaped extrusion plate and generates an extrusion force, and the generated extrusion force can effectively squeeze the absorbent cotton block, prompting it to quickly release the absorbed water;

[0026] Step 4: When the squeezing of the absorbent cotton block and the arc squeezing plate is completed, that is, when the other pair of semicircular plates changes from the open state to the closed state, the second convex tooth begins to mesh with the first gear, the limit plug rod is just separated from the limit plug hole, and one end of the L-shaped limit rod abuts against the inner wall of the square tube, and the L-shaped rod and the connecting rod continue to retreat through the driving motor, the connecting rod drives the first gear to rotate under the meshing action of the second convex tooth and the first gear, and the first gear drives the second gear meshed with it to rotate, and the second gear drives the moving rod to retreat through the meshing action with the first convex tooth, and the moving rod drives the arc-shaped squeezing plate fixedly connected to it to retreat, so that the arc-shaped squeezing plate is away from the absorbent cotton block, so that the absorbent cotton block returns to a certain thickness, which helps to increase its contact area with the air, thereby further improving the drying efficiency of the absorbent cotton block, and the push-pull rod no longer continues to follow the movement of the connecting rod under the limiting action of the L-shaped limit rod, the telescopic spring is compressed, and an opening process is completed;

[0027] Step 5: When the pair of semicircular plates opened by the L-shaped rod are closed, the first gear and the second convex tooth, as well as the second gear and the first convex tooth are in meshing state before closing, and the limit plug rod is separated from the limit plug hole; when the L-shaped rod drives the vertical rod to move toward the direction of the semicircular plate, the vertical rod drives the connecting rod to move synchronously, and when the connecting rod moves, the telescopic spring gradually resets until the limit plate contacts the inner wall of the side of the moving groove away from the semicircular plate again. At the same time, the connecting rod drives the first gear meshed with it to rotate through the second convex tooth, and the first gear drives the second gear meshed with it to rotate, and the second gear is connected to the semicircular plate by the second convex tooth. The first convex tooth engaged with the gear drives the moving rod to move in the direction of the semicircular plate, and the moving rod drives the arc-shaped water squeezing plate to move in the direction of the semicircular plate and gradually squeezes the absorbent cotton block. When the second convex tooth is just separated from the first gear and the limit plug rod is just in contact with the limit plug hole, the vertical rod and the connecting rod continue to be driven to move. At this time, the limit plug rod and the limit plug hole are adapted to be plugged, and the connecting rod no longer drives the first gear to rotate through the second convex tooth, that is, the arc-shaped water squeezing plate no longer moves, and the connecting rod drives the drag rod to move under the limiting action of the limit plate and the inner wall of the moving groove, and the push-pull rod drives the semicircular plate to close, completing a closing process;

[0028] Step 6: The water released in step 3 is discharged from the drying box through the first drain pipe, the U-shaped pipe and the second drain pipe on the bottom wall of the square tube.

[0029] Beneficial effects of the present invention:

[0030] 1. In the present invention, when one pair of semicircular plates is saturated with water, the driving motor drives the forward and reverse screws to rotate, so that one pair of L-shaped rods move away from or closer to each other, and the other pair of L-shaped rods move closer to or away from each other, so that the closed pair of semicircular plates can be opened and the opened pair of semicircular plates can be closed, so that the water droplets on the surface of the cable can be absorbed by the absorbent cotton strips and the absorbent cotton blocks in turn, without interrupting the drying process, and the cable drying efficiency can be improved.

[0031] 2. In the present invention, during the opening process of the closed semicircular plate, the squeezing effect of the arc-shaped squeezing plate and the semicircular plate can effectively squeeze the absorbent cotton blocks, prompting them to quickly release the absorbed moisture, and then the absorbent cotton blocks and absorbent cotton strips are dried by the high temperature environment and circulating hot air in the drying box. This operation can improve the drying efficiency of the absorbent cotton blocks and absorbent cotton strips, and it is not easy for the previous group of absorbent cotton blocks and absorbent cotton strips to be not completely dried while the other group of absorbent cotton blocks has reached a saturated state, thereby not easily affecting the drying effect and drying efficiency of the cable.

[0032] 3. In the present invention, after squeezing the absorbent cotton block to quickly release the absorbed moisture, the arc-shaped squeezing plate can be retreated and away from the absorbent cotton block through the coordinated use of the first gear, the second gear, the first convex tooth, the second convex tooth, the limiting plug rod, the moving rod, the L-shaped limiting rod, etc. This design can restore the absorbent cotton block to a certain thickness, thereby helping to increase the contact area between the absorbent cotton block and the air, and further improving the drying efficiency of the absorbent cotton block.

[0060] Specifically, Figure 7-8 The water absorption component 301 includes a square tube 301-1 corresponding to the wire inlet hole 102. The bottom of one side of the square tube 301-1 is fixedly connected to the inner wall of the drying box 101 through an extension plate for fixing the square tube 301-1. A pair of semicircular plates 301-2 are symmetrically arranged inside the square tube 301-1. The pair of semicircular plates 301-2 can form a full circle when closed. The side of the pair of semicircular plates away from each other is fixedly connected with a water-absorbing cotton block 301-3. The side of the water-absorbing cotton block 301-3 facing the semicircular plate 301-2 is fixedly connected with a pair of water-absorbing cotton strips 301-4. The water-absorbing cotton The strip 301-4 is arc-shaped and consistent with the center of the semicircular plate 301-2.

A pair of moving rods 301-9 are fixedly connected to the sides of the pair of arc-shaped extrusion plates 301-5 that are away from each other. The first convex teeth 301-10 are fixedly connected to the opposite sides of the pair of moving rods 301-9 in a linear array. The moving rods 301-9 slide through the square tube 301-1. The first convex teeth 301-10 are located outside the square tube 301-1. The first convex teeth 301-10 and the push-pull rod 301-6 are connected to the moving extrusion assembly 302;

When a pair of semicircular plates 301-2 are closed, the end of the L-shaped limit rod 301-12 away from the push-pull rod 301-6 does not contact the inner wall of the square tube 301-1. When the L-shaped limit rod 301-12 contacts the square tube 301-1, the position of the semicircular plate 301-2 can be limited so that it no longer moves with the connecting rod 302-1.

[0063] Furthermore, Figure 7 The inner walls on both sides of the square tube 301-1 are fixedly connected with limiting flow rings 301-11 to prevent water from overflowing.

The upper and lower sides of the pair of connecting rods 302-1 are fixedly connected with second protruding teeth 302-2 in a linear array. The pair of connecting rods 302-1 and the second protruding teeth 302-2 fixedly connected to the upper and lower sides slide through the front and rear sides of the square tube 301-1 respectively. The opposite sides of the pair of connecting rods 302-1 are provided with grooves 302-3. The inner walls of the upper and lower sides of the grooves 302-3 are provided with moving grooves 302-4.

A first gear 302-6 and a second gear 302-7 are rotatably installed on one side of each fixing plate 302-5 through a bearing. The first gear 302-6 and the second gear 302-7 are meshed and connected. The first gear 302-6 is meshed and linked with the second convex tooth 302-2, and the second gear 302-7 is meshed and connected with the first convex tooth 301-10. A connecting column 302-8 is fixedly connected to the center of one side of the first gear 302-6 away from the fixing plate 302-5, and a limited position insertion hole 302-9 is provided on the connecting column 302-8;

[0066] The outer ends of a pair of connecting rods 302-1 are fixedly connected with vertical rods 302-10, and the tops of a pair of vertical rods 302-7 are respectively fixedly connected with L-shaped rods 302-11. The L-shaped rods 302-11 are movably arranged above the square tube 301-1. A pair of L-shaped rods 302-11 on one of the square tubes 301-1 are connected to the driving assembly 303. The vertical rods 302-10 and the corresponding positions of the limit plug holes 302-9 are fixedly connected with the limit plug rods 302-12. The limit plug rods 302-12 and the limit plug holes 302-9 are adapted for sliding connection. Through the plug-in action of the limit plug rods 302-12 and the limit plug holes 302-9, the first gear 302-6 can be stabilized so that the first gear 302-6 remains in a stable state when it is not engaged with the second convex tooth 302-2.

[0067] Specifically, Fig.14The driving assembly 303 includes a pair of side plates 303-1 symmetrically fixed to the top of the square tube 301-1, and a forward and reverse screw rod 303-2 is rotatably installed between the pair of side plates 303-1 through a bearing. A driving motor 303-3 is fixedly installed on one of the side plates 303-1 by bolts, and the output end of the driving motor 303-3 is fixedly connected to one end of the forward and reverse screw rod 303-2. A pair of L-shaped rods 302-11 are symmetrically arranged on the forward and reverse screw rods 303-2 and are threadedly connected to the forward and reverse screw rods 303-2. The pair of side plates 303-1 are respectively adapted to slide with the cross bars of a pair of L-shaped rods 302-11 for guiding the movement of the L-shaped rods 302-11.

[0068] Specifically, Figure 6 The synchronization assembly 304 includes a first synchronization rod 304-1 and a second synchronization rod 304-2, which are spaced apart from each other. One end of the first synchronization rod 304-1 and the second synchronization rod 304-2 are respectively fixedly connected to a pair of L-shaped rods 302-11, and the other ends of the first synchronization rod 304-1 and the second synchronization rod 304-2 are respectively fixedly connected to another pair of L-shaped rods 302-11, and both ends of the first synchronization rod 304-1 and the second synchronization rod 304-2 are obliquely corresponding, so that the moving directions of the semicircular plates 301-2 in the two square tubes 301-1 are always opposite.

[0069] In summary, when in use, the driving motor 303-3 is started, and the driving motor 303-3 operates to cause the closed pair of semicircular plates 301-2 to open and squeeze the water-saturated absorbent cotton block 301-3, so as to squeeze out the water and accelerate the drying efficiency of the water-saturated absorbent cotton block 301-3, while causing the other pair of opened semicircular plates 301-2 to close and absorb water; the specific process is: the driving motor 303-3 operates to drive the forward and reverse screw rods 303-2 to rotate, and when the forward and reverse screw rods 303-2 operate, a pair of L-shaped rods 302-11 threadedly connected thereto approach or move away from each other, and a pair of L-shaped rods 302-11 drive another pair of L-shaped rods 302-11 to move away from or approach each other through the first synchronization rod 304-1 and the second synchronization rod 304-2;

[0070] When the closed pair of semicircular plates 301-2 are opened by the L-shaped rod 302-11, the first gear 302-6 is separated from the second protruding tooth 301-10 before opening, and the second gear 302-7 is meshed and connected with the first protruding tooth 301-10, and the limit rod 302-12 is adapted to slide with the limit hole 302-9; when the L-shaped rod 302-11 drives the vertical rod 302-10 to move away from the semicircular plate 301-2, the vertical rod 302-10 pulls the push-pull rod 301-6 under the limiting action of the limiting plate 301-7 and the inner wall of the movable groove 302-4 to drive the semicircular plate 301-2 to retreat, and the semicircular plate 301-2 drives the absorbent cotton block 301-3 to retreat. During the retreat process, the absorbent cotton block 301-3 contacts the arc-shaped extrusion plate 301-5 and generates an extrusion force, which can effectively squeeze the absorbent cotton block 301-3 and prompt it to quickly release the absorbed water;

[0071] When the water-absorbing cotton block 301-3 and the arc-shaped extrusion plate 301-5 are squeezed, that is, the other pair of semicircular plates 301-2 are changed from the open state to the closed state, the second convex tooth 301-10 begins to mesh with the first gear 302-6, the limit plug rod 302-12 is just separated from the limit plug hole 302-9, and one end of the L-shaped limit rod 301-12 abuts against the inner wall of the square tube 301-1, and the L-shaped rod 302-11 and the connecting rod 302-1 continue to retreat through the driving motor 303-3. The connecting rod 302-1 drives the first gear 302-6 to rotate under the meshing action of the second convex tooth 301-10 and the first gear 302-6, and the first gear 302-6 drives the meshing with it The second gear 302-7 connected to the connecting rod rotates, and the second gear 302-7 drives the moving rod 301-9 to retreat through the meshing action with the first convex tooth 301-10, and the moving rod 301-9 drives the arc-shaped water squeezing plate 301-5 fixedly connected thereto to retreat, so that the arc-shaped water squeezing plate 301-5 is away from the absorbent cotton block 301-3, so that the absorbent cotton block 301-3 is restored to a certain thickness, which helps to increase its contact area with the air, thereby further improving the drying efficiency of the absorbent cotton block 301-3, and the push-pull rod 301-6 no longer continues to follow the movement of the connecting rod 302-1 under the limiting action of the L-shaped limiting rod 301-12, and the telescopic spring 301-8 is compressed to complete an opening process.

[0072] Example 2

[0073] Reference Figure 5 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the water absorption unit 300 further includes a drainage component 305, and the drainage component 305 is fixedly connected to the bottom of a pair of water absorption components 301;

[0074] The drainage assembly 305 includes a first drainage pipe 305-1 fixedly connected to the bottom of the two square tubes 301-1 respectively. The bottom end of the first drainage pipe 305-1 extends out of the drying box 101 and is fixedly connected to the same U-shaped pipe 305-2. The bottom end of the U-shaped pipe 305-2 is fixedly connected to the second drainage pipe 305-3, and a valve is installed on the second drainage pipe 305-3.

[0075] The remaining structures are the same as those of Example 1.

[0076] When in use, the moisture released by squeezing the absorbent cotton block 301-3 is discharged from the drying box 101 through the first drain pipe 305-1, the U-shaped pipe 305-2 and the second drain pipe 305-3 on the inner bottom wall of the square tube 301-1, and will not be retained in the drying box 101, thereby reducing the humidity inside the drying box 101 to improve the cable drying effect.

[0077] The drying method using the above cable drying device for cable production is:

[0078] In the initial state, a pair of semicircular plates 301-2 in the two square tubes 301-1 are in a closed state and an open state respectively (such as Figure 6 ), the cable to be dried enters the drying box 101 through the cable inlet 102, then absorbs water droplets through a pair of square tubes 301-1, and finally passes through the drying unit 200 to be dried and then exits from the cable outlet 103, completing the drying process.

[0079] When the cable passes through the square tube 301-1, the absorbent cotton strips 301-4 on the closed pair of semicircular plates 301-2 absorb the water drops on the cable. After a period of time, the absorbent cotton blocks 301-3 on the closed pair of semicircular plates 301-2 are saturated with water. Then, the driving motor 303-3 is started. The driving motor 303-3 operates to open the closed pair of semicircular plates 301-2 and squeeze the absorbent cotton blocks 301-3 saturated with water, so as to squeeze out the water and accelerate the absorption of the absorbent cotton. The drying efficiency of block 301-3 is improved, and at the same time, the other pair of opened semicircular plates 301-2 are closed to absorb water; the specific process is: the driving motor 303-3 drives the forward and reverse screw rods 303-2 to rotate, and when the forward and reverse screw rods 303-2 are running, a pair of L-shaped rods 302-11 threadedly connected thereto approach or move away from each other, and a pair of L-shaped rods 302-11 drive another pair of L-shaped rods 302-11 to move away from or approach each other through the first synchronization rod 304-1 and the second synchronization rod 304-2.

[0080] If the closed pair of semicircular plates 301-2 are opened by the L-shaped rod 302-11, the first gear 302-6 is separated from the second convex tooth 301-10 before opening, and the second gear 302-7 is meshed and connected with the first convex tooth 301-10, and the limiting plug rod 302-12 is adapted to slide with the limiting plug hole 302-9; when the L-shaped rod 302-11 drives the vertical rod 302-10 to move away from the semicircular plate 301-2, the vertical rod 302-10 pulls the push-pull rod 301-6 under the limiting action of the limiting plate 301-7 and the inner wall of the moving groove 302-4 to drive the semicircular plate 301-2 to retreat, and the semicircular plate 301-2 drives the absorbent cotton block 301-3 to retreat. During the retreat process, the absorbent cotton block 301-3 contacts the arc-shaped extrusion plate 301-5 and generates an extrusion force (such as Fig.11 ), the squeezing force generated can effectively squeeze the absorbent cotton block 301-3, prompting it to quickly release the absorbed water.

[0081] When the water-absorbing cotton block 301-3 and the arc-shaped extrusion plate 301-5 are squeezed, that is, when the other pair of semicircular plates 301-2 are changed from the open state to the closed state, the second convex tooth 301-10 begins to mesh with the first gear 302-6, the limit rod 302-12 is just separated from the limit plug hole 302-9, and one end of the L-shaped limit rod 301-12 abuts against the inner wall of the square tube 301-1, and the L-shaped rod 302-11 and the connecting rod 302-6 are driven by the driving motor 303-3. -1 continues to move backward, the connecting rod 302-1 drives the first gear 302-6 to rotate under the meshing action of the second protruding tooth 301-10 and the first gear 302-6, and the first gear 302-6 drives the second gear 302-7 meshed with it to rotate, and the second gear 302-7 drives the moving rod 301-9 to move backward through the meshing action with the first protruding tooth 301-10, and the moving rod 301-9 drives the arc-shaped squeezing plate 301-5 fixedly connected thereto to move backward (such as Fig.12 ), so that the arc-shaped squeezing plate 301-5 is away from the absorbent cotton block 301-3, so that the absorbent cotton block 301-3 is restored to a certain thickness, which helps to increase its contact area with the air, thereby further improving the drying efficiency of the absorbent cotton block 301-3, and the push-pull rod 301-6 no longer continues to move with the connecting rod 302-1 under the limiting action of the L-shaped limiting rod 301-12, and the telescopic spring 301-8 is compressed (such as Fig.13 ) to complete the opening process.

[0082] When the pair of semicircular plates 301-2 opened by the L-shaped rod 302-11 are closed, the first gear 302-6 and the second protruding tooth 301-10, the second gear 302-7 and the first protruding tooth 301-10 are in meshing state before closing, and the limiting rod 302-12 is separated from the limiting hole 302-9 (such as Fig.13), when the L-shaped rod 302-11 drives the vertical rod 302-10 to move toward the direction of the semicircular plate 301-2, the vertical rod 302-10 drives the connecting rod 302-1 to move synchronously. When the connecting rod 302-1 moves, the telescopic spring 301-8 gradually resets until the limit plate 301-7 contacts the inner wall of the moving groove 302-4 away from the semicircular plate 301-2 again. At the same time, the connecting rod 302-1 drives the first gear 302-6 meshed with it to rotate through the second convex tooth 302-2, and the first gear 302-6 drives the second gear 302-7 meshed with it to rotate. The second gear 302-7 drives the moving rod 301-9 to move toward the direction of the semicircular plate 301-2 through the first convex tooth 302-2 meshed with it. The moving rod 301-9 drives the arc water squeezing The plate 301-5 moves toward the semicircular plate 301-2 and gradually squeezes the absorbent cotton block 301-3. When the second convex tooth 302-2 is just separated from the first gear 302-6, and the limiting plug rod 302-12 is just in contact with the limiting socket 302-9, it continues to drive the vertical rod 302-10 and the connecting rod 302-1 to move. At this time, the limiting plug rod 302-12 is adapted to be plugged into the limiting socket 302-9, and the connecting rod 302-1 no longer drives the first gear 302-6 to rotate through the second convex tooth 302-2, that is, the arc-shaped water squeezing plate 301-5 no longer moves, and the connecting rod 302-1 drives the drag rod 301-6 to move under the limiting action of the limiting plate 301-7 and the inner wall of the moving groove 302-4, and the push-pull rod 301-6 drives the semicircular plate 301-2 to close, completing a closing process.

[0083] The moisture released from the absorbent cotton block 301 - 3 is discharged from the drying box 101 through the first drain pipe 305 - 1 , the U-shaped pipe 305 - 2 and the second drain pipe 305 - 3 on the inner bottom wall of the square tube 301 - 1 .

The drying method of the cable drying device for cable production according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: In the initial state, the pair of semicircular plates (301-2) in the two square tubes (301-1) are respectively in a closed state and an open state, and the cable to be dried enters the drying box (101) through the wire inlet hole (102), then absorbs water droplets through the pair of square tubes (301-1), and then is dried by the drying unit (200) and then exits from the wire outlet hole (102), completing the drying process; Step 2: When the cable passes through the square tube (301-1), the water-absorbing cotton strips (301-4) on the closed pair of semicircular plates (301-2) absorb the water drops on the cable. After a period of time, the water-absorbing cotton blocks (301-3) on the closed pair of semicircular plates (301-2) are saturated with water. Then, the driving motor (303-3) is started. The driving motor (303-3) operates to open the closed pair of semicircular plates (301-2) and squeeze the water-absorbing cotton blocks (301-3) saturated with water, so as to squeeze out the water and accelerate the water absorption. The cotton block (301-3) is dried efficiently, and at the same time, another pair of opened semicircular plates (301-2) are closed to absorb water; the specific process is as follows: the driving motor (303-3) is operated to drive the forward and reverse screw rods (303-2) to rotate, and when the forward and reverse screw rods (303-2) are operated, a pair of L-shaped rods (302-11) threadedly connected thereto are moved closer to or farther away from each other, and a pair of L-shaped rods (302-11) drive another pair of L-shaped rods (302-11) to move away from or closer to each other through a first synchronous rod (304-1) and a second synchronous rod (304-2); Step 3: When the closed pair of semicircular plates (301-2) are driven to open by the L-shaped rod (302-11), the first gear (302-6) and the second protruding tooth (301-10) are separated before opening, and the second gear (302-7) is meshed and connected with the first protruding tooth (301-10), and the limit plug rod (302-12) and the limit plug hole (302-9) are adapted and slidably connected; when the L-shaped rod (302-11) drives the vertical rod (302-10) to move away from the semicircular plate (301-2), , the vertical rod (302-10) pulls the push-pull rod (301-6) to drive the semicircular plate (301-2) to retreat under the limiting action of the limiting plate (301-7) and the inner wall of the movable groove (302-4), and the semicircular plate (301-2) drives the water-absorbing cotton block (301-3) to retreat. During the retreat process, the water-absorbing cotton block (301-3) contacts the arc-shaped squeezing plate (301-5) and generates squeezing force, and the generated squeezing force can effectively squeeze the water-absorbing cotton block (301-3) to prompt it to quickly release the absorbed water; Step 4: When the water-absorbing cotton block (301-3) and the arc-shaped extrusion plate (301-5) are squeezed, that is, when the other pair of semicircular plates (301-2) are changed from the open state to the closed state, the second convex tooth (301-10) begins to mesh with the first gear (302-6), the limit plug rod (302-12) is just separated from the limit plug hole (302-9), and one end of the L-shaped limit rod (301-12) abuts against the inner wall of the square tube (301-1), and the L-shaped rod (302-11) and the connecting rod (302-1) continue to retreat through the driving motor (303-3), the connecting rod (302-1) drives the first gear (302-6) to rotate under the meshing action of the second convex tooth (301-10) and the first gear (302-6), and the first gear (302-6) The second gear (302-7) meshing with the second gear (302-7) is driven to rotate. The second gear (302-7) meshes with the first convex tooth (301-10) to drive the moving rod (301-9) to retreat. The moving rod (301-9) drives the arc-shaped water squeezing plate (301-5) fixedly connected with the moving rod (301-5) to retreat, so that the arc-shaped water squeezing plate (301-5) is away from the absorbent cotton block (301-3), so that the absorbent cotton block (301-3) is restored to a certain thickness, which helps to increase its contact area with the air, thereby further improving the drying efficiency of the absorbent cotton block (301-3). The push-pull rod (301-6) no longer continues to follow the connection rod (302-1) under the limiting action of the L-shaped limiting rod (301-12), and the telescopic spring (301-8) is compressed, completing an opening process. Step 5: When the pair of semicircular plates (301-2) opened by the L-shaped rod (302-11) are closed, the first gear (302-6) and the second protruding tooth (301-10), the second gear (302-7) and the first protruding tooth (301-10) are in a meshing state before closing, and the limiting plug rod (302-12) and the limiting plug hole (302-9) are separated; when the L-shaped rod (302-11) drives the vertical rod (302-10) to move toward the semicircular plate (301-2), the vertical rod (302-10) drives the connecting rod (302-6) to move toward the semicircular plate (301-2). 02-1) moves synchronously, when the connecting rod (302-1) moves, the telescopic spring (301-8) gradually resets until the limit plate (301-7) contacts the inner wall of the moving groove (302-4) away from the semicircular plate (301-2) again, and at the same time, the connecting rod (302-1) drives the first gear (302-6) meshed with it to rotate through the second convex tooth (302-2), and the first gear (302-6) drives the second gear (302-7) meshed with it to rotate, and the second gear (302-7) is connected to it by the second convex tooth (302-2). The meshing first convex tooth (302-2) drives the moving rod (301-9) to move toward the semicircular plate (301-2), and the moving rod (301-9) drives the arc-shaped water squeezing plate (301-5) to move toward the semicircular plate (301-2) and gradually squeezes the water-absorbing cotton block (301-3). When the second convex tooth (302-2) is just separated from the first gear (302-6) and the limiting plug rod (302-12) is just in contact with the limiting plug hole (302-9), the vertical rod (302-10) and the connecting rod (302-12) are continuously driven to move. ) moves, at this time, the limiting plug rod (302-12) is adapted to be plugged into the limiting plug hole (302-9), and the connecting rod (302-1) no longer drives the first gear (302-6) to rotate through the second convex tooth (302-2), that is, the arc-shaped water squeezing plate (301-5) no longer moves, and the connecting rod (302-1) drives the drag rod (301-6) to move under the limiting action of the limiting plate (301-7) and the inner wall of the moving groove (302-4), and the push-pull rod (301-6) drives the semicircular plate (301-2) to close, completing a closing process; Step 6: The water released in step 3 is discharged from the drying box (101) through the first drainage pipe (305-1), the U-shaped pipe (305-2) and the second drainage pipe (305-3) on the inner bottom wall of the square tube (301-1).
