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] A cable is a device for transmitting electrical energy or signals, usually consisting 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, a certain amount of water droplets will remain on the surface of the cable, and the cable needs to be dried to ensure subsequent processing and storage of the cable.

[0003] Existing cable drying devices typically use two sets of absorbent cotton to alternately absorb water droplets from the cable surface before drying the cable with hot air. However, this process presents a problem: when one set of absorbent cotton reaches saturation and needs to be replaced, it typically requires hot air circulation within a drying oven to dry the cable. However, due to the high water absorption capacity of the absorbent cotton, hot air drying is relatively inefficient. This often results in the other set of absorbent cotton not being fully dried by the time the other set reaches saturation, compromising both the drying effect and efficiency of the cable.

[0021] As a preferred solution of the cable drying device for cable production described in the present invention, wherein: the drainage component includes a first drainage pipe fixedly connected to the bottom of the 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 the 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, the 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 cable inlet, then absorbs water droplets through the pair of square tubes, and finally passes through the drying unit to be dried and then exits from the cable outlet, completing 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 droplets 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, thereby accelerating the drying efficiency of the absorbent cotton blocks and closing the other pair of opened semicircular plates to absorb water. The specific process is as follows: the driving motor drives the forward and reverse screw rods to rotate. When the forward and reverse screw rods are in operation, a pair of L-shaped rods threaded therewith move closer to or closer to each other, and a pair of L-shaped rods drive the other pair of L-shaped rods to move closer to or closer to each other through the first synchronization rod and the second synchronization rod.

[0025] Step 3: If the pair of closed semicircular plates are opened by the L-shaped rod, the first gear and the second convex tooth are separated before opening, and the second gear is meshed and connected with the first convex tooth, and the limit plug rod and the limit plug hole are adapted for sliding connection; 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 backward under the limiting action of the limiting plate and the inner wall of the movable groove, and the semicircular plate drives the absorbent cotton block backward. During the retreat process, the absorbent cotton block contacts the arc-shaped extrusion plate and generates an extrusion force. The generated extrusion force can effectively squeeze the absorbent cotton block, prompting it to quickly release the absorbed water;

[0026] The second gear is engaged with the first gear and the second gear is engaged with the first gear, and the second gear is engaged with the first gear and the second gear is engaged with the first gear.

[0027] Step 5: If the pair of semicircular plates opened by the L-shaped rod are closed, the first gear and the second convex tooth, the second gear and the first convex tooth are all in a 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 rotates through the second convex tooth. The first convex tooth engaged with the first convex tooth drives the moving rod to move toward the semicircular plate, and the moving rod drives the arc-shaped water squeezing plate to move toward the semicircular plate and gradually squeezes the water-absorbing cotton block. When the second convex tooth is just separated from the first gear and the limit plug 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 is adapted to be plugged into the limit plug hole, 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 forward and reverse screw rods are driven to rotate by the driving motor, 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, thereby opening the closed pair of semicircular plates and closing the opened pair of semicircular plates, so that the water droplets on the surface of the cable can be absorbed in turn by the absorbent cotton strips and the absorbent cotton blocks, without interrupting the drying process, thereby improving the cable drying efficiency.

[0031] 2. In the present invention, during the opening process of the closed semicircular plate, the squeezing action 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 less likely that the previous group of absorbent cotton blocks and absorbent cotton strips have not been completely dried while the other group of absorbent cotton blocks has reached a saturated state, thereby less likely to affect 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 extrusion 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 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.

[0053] Example 1

[0054] Reference Figure 1-14 , which is the first embodiment of the present invention, provides a cable drying device for cable production, mainly comprising:

[0055] The main unit 100, such as Figure 1-3 The main unit 100 includes a drying box 101. The left and right ends of the drying box 101 are respectively provided with an inlet hole 102 and an outlet hole 103. The upper and lower sides of the drying box 101 are fixedly connected with exhaust pipes 106 for discharging the heat and moisture in the drying box 101, which can improve the cable drying effect. In addition, the four corners of the bottom of the drying box 101 are fixedly connected with support legs 104 for supporting the drying box 101. The rear side of the drying box 101 is an open structure, and the opening is sealed and hinged with an inspection door 105, which is convenient for inspection and maintenance of the internal electrical equipment of the drying box 101. The inspection door 105 is installed with a handle for easy opening of the inspection door 105. The inspection door 105 is fixedly connected to the drying box 101 through a lock body, which is convenient for disassembly and assembly. When in use, the cable enters the drying box 101 through the inlet hole 102 and exits from the outlet hole 103 after drying.

[0056] A pair of drying units 200 are provided and are fixedly connected to the upper and lower sides of the drying box 101 respectively, for drying the cables;

[0057] like Figure 3-4 The drying unit 200 includes an air inlet fan 201 fixedly connected to the upper and lower sides of the drying box 101 by bolts. The air outlet of the air inlet fan 201 is fixedly connected to an air inlet duct 202, which is fixedly installed with an electric heating wire mesh. The bottom end of the air inlet duct 202 extends into the drying box 101 and is fixedly connected to a diversion cross pipe 203. The diversion cross pipe 203 is fixedly connected to a linear array of drying nozzles 204. The drying nozzles 204 in a pair of drying units 200 are respectively arranged on the upper and lower sides of the cable. When drying the cable, the air inlet fan 201 and the electric heating wire mesh are turned on. Natural air from the outside enters the air inlet end of the air inlet fan 201 and enters the air inlet duct 202. The air is then heated by the electric heating wire mesh in the air inlet duct 202 to form hot air. The hot air then enters the diversion cross pipe 203 and is then sprayed onto the cable by a plurality of drying nozzles 204, thereby drying the cable.

[0058] The water absorption unit 300, such as Figure 3The water absorption unit 300 is located inside the drying box 101 and is fixedly connected to the inner wall of the drying box 101. The water absorption unit 300 is located between the cable inlet 102 and the drying unit 200 and is used to absorb water droplets on the surface of the cable;

[0059] like Figure 5 The water absorption unit 300 includes a pair of water absorption components 301, movable extrusion components 302 respectively connected to the pair of water absorption components 301, a driving component 303 fixedly connected to the top of one of the water absorption components 301, and a synchronization component 304 connected to the movable extrusion component 302 on the other water absorption component 301. The pair of water absorption components 301 are arranged in correspondence on the left and right, the driving component 303 is connected to the adjacent movable extrusion component 302, and one end of the synchronization component 304 is fixedly connected to the driving component 303.

[0060] Specifically, such as Figure 7-8 The water absorbing 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. A pair of absorbent cotton blocks 301-3 are fixedly connected to the sides of the pair of semicircular plates away from each other. A pair of absorbent cotton strips 301-4 are fixedly connected to the side of the absorbent cotton block 301-3 facing the semicircular plate 301-2. The strip 301-4 is arc-shaped and is consistent with the center of the semicircular plate 301-2. This arrangement enables the absorbent cotton strip 301-4 to fit in contact with the surface of the cable, thereby better absorbing water droplets. A pair of absorbent cotton strips 301-4 are arranged through the semicircular plate 301-2, and one end of the pair of absorbent cotton strips 301-4 away from each other is aligned with the edge of the semicircular plate 301-2, and the other end is spaced apart from the edge of the semicircular plate 301-1. The purpose of this arrangement is to enable the absorbent cotton strips 301-4 on the semicircular plates 301-2 on both sides to absorb water droplets around the cable.

[0061] like Figure 9, a pair of semicircular plates 301-2 are spaced apart on one side away from each other and are provided with an arc-shaped water squeezing plate 301-5, a pair of semicircular plates 301-2 are symmetrically fixed with a push-pull rod 301-6 on one side away from each other, the push-pull rod 301-6 slides through the absorbent cotton block 301-3 and the arc-shaped water squeezing plate 301-5, the upper and lower sides of the end of the push-pull rod 301-6 away from the semicircular plate 301-2 are fixedly connected to the limit plate 301-7, the limit plate 301-7 is fixedly connected to the side facing the semicircular plate 301-2 with a telescopic spring 301-8, by setting the telescopic spring 3 01-8, which enables the connecting rod 302-1 to move independently while the push-pull rod 301-6 no longer moves. A pair of movable 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 protruding teeth 301-10 are fixedly connected to the opposite sides of the pair of movable rods 301-9 in a linear array. The movable rods 301-9 slide through the square tube 301-1. The first protruding teeth 301-10 are located outside the square tube 301-1. The first protruding teeth 301-10 and the push-pull rod 301-6 are all connected to the movable extrusion assembly 302;

[0062] The upper and lower sides of the push-pull rod 301-6 are fixedly connected to the inside of the square tube 301-1 with L-shaped limit rods 301-12. 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, it can limit the position of the semicircular plate 301-2 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.

[0064] Specifically, such as Figure 10 and Figure 13The movable extrusion assembly 302 includes a pair of connecting rods 302-1 and two pairs of fixed plates 302-5 respectively fixed to the front and rear sides of the square tube 301-1. The upper and lower sides of the pair of connecting rods 302-1 are fixed with second protruding teeth 302-2 in a linear array. The pair of connecting rods 302-1 and the second protruding teeth 302-2 fixed on the upper and lower sides are respectively slidably arranged through the front and rear sides of the square tube 301-1. The opposite sides of the pair of connecting rods 302-1 are each provided with a groove 302-3. The inner walls of the upper and lower sides of the groove 302-3 are each provided with a movable groove 302-4. The push-pull rod 301-6 is connected to the groove 301-6. 02-3 is adapted for sliding connection, a pair of limit plates 301-7 are adapted for sliding connection with a pair of movable grooves 302-4 respectively, and the side of a pair of limit plates 301-7 away from the telescopic spring 301-8 is movably fitted with the side of the movable groove 302-4 away from the telescopic spring 301-8. In this way, when a pair of closed semicircular plates 301-2 are opened, the connecting rod 302-1 can pull the push-pull rod 301-6 and the semicircular plate 301-2 backward through the limiting action of the limit plate 301-7 and the movable groove 302-4, and the telescopic spring 301-8 is fixedly connected to the inner wall of the movable groove 302-4.

[0065] Each pair of fixing plates 302-5 is symmetrically arranged in the upper and lower sides and is respectively located on the upper and lower sides of the connecting rod 302-1. A first gear 302-6 and a second gear 302-7 are rotatably mounted on one side of each fixing plate 302-5 via 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 protruding tooth 302-2, and the second gear 302-7 is meshed and connected with the first protruding tooth 301-10. A connecting column 302-8 is fixedly connected to the center of the side of the first gear 302-6 away from the fixing plate 302-5. A limiting socket 302-9 is defined on the connecting column 302-8.

[0066] The outer ends of a pair of connecting rods 302-1 are fixedly connected to vertical rods 302-10, and the tops of a pair of vertical rods 302-7 are respectively fixedly connected to 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 is connected to the drive assembly 303. The vertical rods 302-10 and the corresponding positions of the limit sockets 302-9 are fixedly connected to the limit rods 302-12. The limit rods 302-12 and the limit sockets 302-9 are adapted for sliding connection. Through the plug-in action of the limit rods 302-12 and the limit sockets 302-9, the first gear 302-6 can be stabilized so that the first gear 302-6 remains stable when it is not engaged with the second convex tooth 302-2.

[0067] Specifically, such as Figure 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 bearings. 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 rod 303-2 and are threadedly connected to the forward and reverse screw rod 303-2. The pair of side plates 303-1 are respectively adapted to slide with the cross bars of the pair of L-shaped rods 302-11 for guiding the movement of the L-shaped rods 302-11.

[0068] Specifically, such as 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 the two ends of the first synchronization rod 304-1 and the second synchronization rod 304-2 are obliquely corresponding to each other, so that the movement 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 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 as follows: 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, the pair of L-shaped rods 302-11 threadedly connected thereto move closer to or farther from each other, and the pair of L-shaped rods 302-11 drive the other pair of L-shaped rods 302-11 to move closer to or farther from each other through the first synchronization rod 304-1 and the second synchronization rod 304-2;

[0070] 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 protruding tooth 301-10 before opening, and the second gear 302-7 is meshed with the first protruding tooth 301-10, and the limiting rod 302-12 is adapted to slide with the limiting 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, driving 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. The generated extrusion force can effectively squeeze the absorbent cotton block 301-3, prompting 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 engage with the first gear 302-6, the limiting plug rod 302-12 is just separated from the limiting plug hole 302-9, and one end of the L-shaped limiting rod 301-12 abuts against the inner wall of the square tube 301-1. When the driving motor 303-3 continues to drive the L-shaped rod 302-11 and the connecting rod 302-1 to continue to retreat, 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 rod 302-6. The second gear 302-7 connected to the coupling 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. The moving rod 301-9 drives the arc-shaped water squeezing plate 301-5 fixedly connected to it 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 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. 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 the 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] During 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 and improving the cable drying effect.

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

[0078] In the initial state, the pair of semicircular plates 301-2 in the two square tubes 301-1 are in the closed and open states respectively (e.g. Figure 6 ), the cable to be dried enters the drying box 101 through the wire inlet 102, then absorbs water droplets through a pair of square tubes 301-1, and is dried by the drying unit 200 and then exits from the wire 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 that are saturated with water, so as to squeeze out the water and speed up the absorption of the absorbent cotton. The block 301-3 is dried efficiently, 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, the pair of L-shaped rods 302-11 threadedly connected thereto move closer to or farther away from each other, and the pair of L-shaped rods 302-11 drive the other pair of L-shaped rods 302-11 to move closer to or farther away from each other through the first synchronization rod 304-1 and the second synchronization rod 304-2.

[0080] When the pair of closed 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 with the first protruding 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 Figure 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 switched from the open state to the closed state, the second protruding tooth 301-10 begins to mesh with the first gear 302-6, the limiting rod 302-12 is just separated from the limiting hole 302-9, and one end of the L-shaped limiting 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 are continuously 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 water squeezing plate 301-5 fixedly connected to it to move backward (as shown in FIG. Figure 12 ), 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 (such as Figure 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 all in meshing state before closing, and the limiting rod 302-12 is separated from the limiting socket 302-9 (such as Figure 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 When the second convex tooth 302-2 is separated from the first gear 302-6 and the limiting rod 302-12 is in contact with the limiting socket 302-9, 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 separated from the first gear 302-6 and the limiting rod 302-12 is in contact with the limiting socket 302-9, the vertical rod 302-10 and the connecting rod 302-1 continue to move. At this time, the limiting 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 movable 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 .

[0084] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

When the forward and reverse screw rods (303-2) are operated, a pair of L-shaped rods (302-11) threadedly connected thereto move closer to or farther away from each other. A pair of L-shaped rods (302-11) drives another pair of L-shaped rods (302-11) to move closer to or farther away from each other through a first synchronization rod (304-1) and a second synchronization 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 limiting plug rod (302-12) and the limiting plug hole (302-9) are adapted and slidably connected; when the L-shaped rod (302-11) drives the vertical rod (302-10) to move in a direction 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), driving the semicircular plate (301-2) to retreat, 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 extrusion plate (301-5) and generates an extrusion force. The generated extrusion force can effectively squeeze the water-absorbing cotton block (301-3), prompting 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 and completed, that is, when the other pair of semicircular plates (301-2) are switched from the open state to the closed state, the second convex tooth (301-10) begins to mesh with the first gear (302-6), the limiting plug rod (302-12) is just separated from the limiting plug hole (302-9), and one end of the L-shaped limiting rod (301-12) abuts against the inner wall of the square tube (301-1). When the driving motor (303-3) drives the L-shaped rod (302-11) and the connecting rod (302-1) to continue to retreat, 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) rotates, and the second gear (302-7) meshes with the first convex tooth (301-10), thereby driving the movable rod (301-9) to retreat. The movable 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) 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 (301-3). 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, 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 all 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, and 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, 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. ) moves, 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 via 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 movable 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).
