Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape production, and in particular to a continuous drying device for adhesive tape production. Background Art

[0002] Adhesive tape is a common adhesive material, usually composed of a substrate (such as paper, cloth, film, etc.) and an adhesive coated on the substrate. During the production of adhesive tape, in order to speed up the fixing process of the adhesive, the adhesive on the substrate needs to be dried to ensure that the adhesive can be firmly attached to the substrate. After the tape is dried, the tape is further processed by subsequent equipment.

[0003] During the tape substrate coating process, the adhesive on the substrate will have periodic uneven thickness due to sticking or vibration. When the adhesive thickness is less than the set value before drying, the adhesive that meets the set thickness will be dried, and the adhesive that is less than the set thickness will be over-dried. When the adhesive is too thin, it will have the effect of over-drying the adhesive, preventing the adhesive from being over-dried by hot air. The hot air will directly skip the adhesive and dry the substrate. The substrate will soften after being heated, and in severe cases it will cause the substrate to melt, thereby causing melting and sagging, further affecting the quality of the finished tape.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0034] The present invention aims to solve the problem that when the thickness of the adhesive coating on the tape is thin, hot air penetrates the adhesive and dries the tape, which causes the substrate to soften due to the heat. In the process of drying the substrate 1, the stretchability of the substrate 1 is detected. When the substrate 1 becomes loose, the movement of the baffle plate 15 is triggered to change the air outlet position of the first air outlet box 14, so as to avoid the first air outlet box 14 still drying the fusible position of the substrate 1 after the substrate 1 becomes loose, causing the substrate 1 to continue to soften due to the heat, thereby causing the phenomenon of melting and sagging.

[0035] Embodiment 1: A continuous drying device for producing adhesive tape, such as Figure 1-Figure 5As shown, a drying box 10 is provided, and the drying box 10 is provided with a control terminal 11. A first air inlet duct 12 is fixedly connected to the right part of the upper side of the drying box 10. The first air inlet duct 12 is fixedly connected to and connected with an air inlet box 13 on one side of the drying box 10. The left side of the air inlet box 13 is fixedly connected and connected with a first air outlet box 14 through a plurality of connecting rings. The air inlet box 13 and the first air outlet box 14 are both fixedly connected to the drying box 10. The left side of the first air outlet box 14 is provided with air outlets distributed in a mirror image and in a linear array. A baffle plate 15 is limitedly slidably connected in the first air outlet box 14. An air guide port is provided in the baffle plate 15. The initial baffle plate 15 The initial position is: the upper side of the baffle plate 15 blocks the air outlets on the first air outlet box 14 that are arranged in a linear array on the upper side, the air guide port in the baffle plate 15 is connected to the air outlets on the first air outlet box 14 that are arranged in a linear array on the lower side, the baffle plate 15 is used to control the air outlets of the first air outlet box 14, a first exhaust duct 16 is fixedly connected to the left portion of the upper side of the drying box 10, the first exhaust duct 16 is fixedly connected to and connected to an exhaust box 17 on one side of the drying box 10, the exhaust box 17 is provided with exhaust ports distributed in a rectangular array on one side facing the first air outlet box 14, the exhaust box 17 is located on the left side of the drying box 10, and the air inlet box 13 is connected to the first air outlet box 14. Located on the right side of the drying box 10, the hot air ejected from the air outlet of the air inlet box 13 dries the adhesive on the substrate 1 to remove moisture in the adhesive, and the continuous blowing of the air outlet of the air inlet box 13 is used to achieve continuous drying of the substrate 1. The exhaust box 17 extracts the air blown out of the air inlet box 13 to achieve gas circulation in the drying box 10. The several exhaust ports on the exhaust box 17 and the mirror-image and linear array air outlets on the first air outlet box 14 are parallel to the ground and are used to dry the adhesive on the substrate 1 in a flat manner. By changing the position of the air jet from the first air outlet box 14, the substrate 1 can be dried. 1 The temperature of the substrate 1 close to the first air outlet box 14 is greater than the temperature of the substrate 1 away from the first air outlet box 14, so as to realize gradual drying of the substrate 1 and make the substrate 1 gradually adapt to the temperature of the hot air. A roller 18 is rotatably connected to the middle part of the drying box 10. The drying box 10 is provided with a plurality of supporting rollers. The plurality of supporting rollers and the roller 18 on the drying box 10 are all in contact with the substrate 1. The substrate 1 is located between the roller 18 and the first air outlet box 14 and the exhaust box 17. A stretch detection component and a drive component are provided on the air inlet box 13. The stretch detection component is used to detect the stretch of the substrate 1, and the drive component is used to drive the shielding plate 15 to slide.

[0036] like Figure 5 and Figure 6As shown, the stretching detection component includes two first U-shaped frames 20 distributed in front and back mirror images, and the two first U-shaped frames 20 distributed in front and back mirror images are both fixedly connected to the lower side of the air inlet box 13. The two first U-shaped frames 20 distributed in front and back mirror images are commonly slidably connected with an anti-sticking member 21 that is squeezed and matched with the substrate 1. The anti-sticking member 21 consists of an internal fixed rod and an external anti-sticking roller, and the anti-sticking roller rotates along the outer ring of the fixed rod. The right part of the lower side of the air inlet box 13 is slidably connected with two L-shaped frames 22 distributed in front and back mirror images, and the left sides of the two L-shaped frames 22 distributed in front and back mirror images are both fixedly connected with limit blocks 23 distributed in a vertical linear array, and an inclined surface is arranged on the left side of the limit block 23. The left part of the lower side of the air inlet box 13 is fixedly connected with a fixed frame 24 distributed in front and back mirror images, and the fixed frame 24 is slidably matched with the adjacent L-shaped frame 22. A spring is arranged between the fixed frame 24 and the adjacent L-shaped frame 22, and this spring is used to bring The adjacent L-shaped frame 22 is moved to reset and slide, and the right side of the fixed frame 24 is limited and slidably connected with an elastic limit pin 25 distributed in a vertical linear array. An inclined surface is arranged on the right side of the elastic limit pin 25. The number of the elastic limit pins 25 is consistent with the number of the limit blocks 23. The inclined surfaces of the limit blocks 23 and the adjacent elastic limit pins 25 are squeezed and matched with the anti-sticking component 21. The gravity of the anti-sticking component 21 is greater than the sum of the supporting forces provided by the adjacent springs of the L-shaped frame 22 and the adjacent springs of the elastic limit pins 25. When the substrate 1 is not loose, the substrate 1 cooperates with the adjacent limit blocks 23 and the adjacent elastic limit pins 25 to support the anti-sticking component 21, so as to achieve the limitation of the anti-sticking component 21. When the substrate 1 is loose, the anti-sticking component 21 lacks the support of the substrate 1, and under the action of its own gravity, the adjacent limit blocks 23 and the adjacent elastic limit pins 25 are squeezed.

[0037] like Figure 5 and Figure 6As shown, the drive assembly includes two oil storage parts 30 distributed in front and back mirror images, and the two oil storage parts 30 distributed in front and back mirror images are fixedly connected to the right side of the air inlet box 13. Hydraulic oil is stored in the oil storage parts 30. The oil storage parts 30 are limited and sealed and slidably connected with a seal 31. The seal 31 is composed of a sliding rod, a round plate and an L-shaped rod. The left side of the L-shaped rod on the seal 31 contacts and cooperates with the adjacent L-shaped frame 22. A spring distance sensor that is squeezed and matched with the adjacent seal 31 is arranged in the oil storage part 30. The spring distance sensor is used to monitor the sliding of the adjacent seal 31. The part of the seal 31 located in the adjacent oil storage part 30 is fixedly connected to two liquid guide tubes 32. The diameter of the seal 31 located in the upper liquid guide tube 32 is larger than the diameter of the seal 31 located in the lower liquid guide tube 32. A one-way valve is provided. When the sealing member 31 moves to the right, the one-way valve located in the upper liquid guiding tube 32 is in an open state, and the one-way valve located in the lower liquid guiding tube 32 is in a closed state. When the sealing member 31 moves to the left, the one-way valve located in the upper liquid guiding tube 32 is in a closed state, and the one-way valve located in the lower liquid guiding tube 32 is in an open state. The upper sides of the air inlet box 13 and the first air outlet box 14 are fixedly connected with guide members 33 with front and rear mirror distribution. A connecting rope 34 is fixedly connected to the left side of the sliding rod on the sealing member 31. The connecting rope 34 contacts and cooperates with the two guide members 33 on the same side. The left end of the connecting rope 34 is fixedly connected to the baffle plate 15. When the connecting rope 34 is pulled, the connecting rope 34 drives the baffle plate 15 to slide upward along the first air outlet box 14, thereby changing the air outlet position of the first air outlet box 14.

[0038] When it is necessary to dry the substrate 1, the staff connects the air outlet of the hot air supply device to the upper side of the first air inlet pipe 12, and then connects the air outlet of the first exhaust device to the upper side of the first exhaust pipe 16, thereby completing the preparation actions before drying the substrate 1.

[0039] After the preparations for drying the substrate 1 are completed, the staff puts the substrate 1 into the drying box 10, passes the substrate 1 through the left side of the drying box 10 and makes the lower side of the substrate 1 contact with the upper side of the roller 18, and then passes the substrate 1 through the lower side of the anti-adhesive member 21 until it passes out of the right side of the drying box 10, and finally places the right side of the substrate 1 on the traction part of the external traction device (the external traction device is not shown in the figure), so that the substrate 1 is in a state of being Figure 4 The substrate 1 is placed in the state of being in the middle, and the substrate 1 is in contact with the lower side of the outer periphery of the anti-sticking member 21, thereby completing the placement of the substrate 1, and then the staff starts the hot air supply equipment and the first exhaust equipment through the control terminal 11, the hot air supply equipment transports the hot air to the air inlet box 13 through the first air inlet pipe 12, the air inlet box 13 transports the hot air to the first air outlet box 14 through all the connecting rings on the left side, and the hot air is ejected from all the air outlets on the left side of the first air outlet box 14, the first exhaust equipment draws the gas in the drying box 10 into the exhaust box 17, and the gas is discharged from the first exhaust pipe 16.

[0040] The hot air ejected from the air outlet on the left side of the first air outlet box 14 contacts the upper side of the substrate 1, changing the existing vertical hot air spraying into the parallel hot air spraying in the present invention to realize the drying treatment of the adhesive on the upper side of the substrate 1, and by spraying hot air from right to left, the temperature of the left side of the substrate 1 in contact with the hot air is lower than the temperature of the right side of the substrate 1 in contact with the hot air, thereby realizing gradual drying of the substrate 1 and making the substrate 1 gradually adapt to the temperature of the hot air.

[0041] When the substrate 1 on the right side in the drying box 10 becomes loose, it indicates that the coating thickness of the substrate 1 is thin. At this time, in order to prevent the subsequent substrate 1 from being over-dried, the anti-sticking member 21 slides downward under the action of gravity and squeezes a part of the substrate 1, so that the substrate 1 is stretched, thereby ensuring the stretching degree of the substrate 1 during the drying process.

[0042] During the downward movement of the anti-sticking member 21, the right side of the adjacent elastic limit pin 25 is squeezed, causing the right side of the adjacent elastic limit pin 25 to move to the left. The L-shaped frame 22 and the limit block 23 close to the anti-sticking member 21 are squeezed by the anti-sticking member 21 to move to the right along the air inlet box 13. During the movement of the L-shaped frame 22, the adjacent spring is squeezed. The limit block 23 and the elastic limit pin 25 close to the anti-sticking member 21 are squeezed by the anti-sticking member 21 to be separated from the limit of the anti-sticking member 21. The anti-sticking member 21 moves downward under the action of its own gravity, thereby completing the stretching of the substrate 1.

[0043] The limit block 23 close to the anti-adhesive member 21 drives the adjacent L-shaped frame 22 to move to the right and squeeze the adjacent sealing member 31. The sealing member 31 moves in the adjacent oil storage member 30 (the spring portion of the spring distance sensor is squeezed during the movement of the sealing member 31), so that the hydraulic oil in the oil storage member 30 pushes open the adjacent one-way valve in the upper liquid guide tube 32 and flows through the upper liquid guide tube 32. During the movement of the sealing member 31, the adjacent connecting rope 34 is driven to drag the shielding plate 15 (the connecting rope 34 moves along the adjacent guiding member 33 during the process of being dragged). During the upward movement of the shielding plate 15, the first air outlet box 14 is pressed against the sealing member 31. The air outlets arranged in a linear array on the lower side are blocked, so that the air guide ports on the shielding plate 15 are connected to the air outlets arranged in a linear array on the upper side of the first air outlet box 14, so as to achieve the effect of switching the air outlet of the first air outlet box 14, and by switching the air outlet of the first air outlet box 14, a height difference is generated between the position where the first air outlet box 14 currently sprays hot air and the substrate 1, thereby reducing the drying intensity of the hot air sprayed by the first air outlet box 14, and preventing the first air outlet box 14 from still drying the fusible position of the substrate 1 in a short distance after the substrate 1 becomes loose, causing the substrate 1 to continue to soften due to heat, thereby causing the phenomenon of melting and sagging.

[0044] After the air outlet position of the first air outlet box 14 is changed, the drying intensity of the substrate 1 is reduced accordingly, so that the portion of the substrate 1 located in the drying box 10 will not continue to stretch.

[0045] When the anti-adhesive member 21 stops moving downward, the adjacent limit block 23 and the adjacent elastic limit pin 25 located on the upper side of the anti-adhesive member 21 are reset successively, and the L-shaped frame 22 and the limit block 23 are reset and moved under the action of the spring and lose the squeeze on the adjacent sealing member 31. The sealing member 31 is reset and moved under the action of the spring portion of the spring distance sensor, so that the hydraulic oil in the oil storage member 30 pushes open the one-way valve in the adjacent and lower liquid guide pipe 32, and flows through the lower liquid guide pipe 32. Due to the different apertures, the speed of the seal 31 when it resets to the left is slower than the speed when it moves to the right. After the seal 31 resets, it no longer drags the baffle plate 15 through the adjacent connecting rope 34. The baffle plate 15 slowly resets to block the air outlet of the upper linear array of the first air outlet box 14, so that the air outlet of the lower linear array of the first air outlet box 14 is gradually connected with the air guide port of the baffle plate 15, and the air outlet of the lower linear array of the first air outlet box 14 continues to dry the subsequent substrate 1.

[0046] When the anti-sticking member 21 falls down to contact with the upper side of the next group of two adjacent limit blocks 23 and the elastic limit pin 25, under the effect that the substrate 1 is no longer stretched, the lower side of the anti-sticking member 21 contacts with the upper side of the next group of two adjacent limit blocks 23 and the elastic limit pin 25, and the upper side of the anti-sticking member 21 contacts with the lower side of the previous group of two adjacent limit blocks 23 and the elastic limit pin 25, so as to limit the anti-sticking member 21.

[0047] After the anti-sticking piece 21 stops falling, the substrate 1 is no longer stretched. At this time, the staff will perform subsequent processing on the substrate 1 that has an unexpected situation (unexpected situation: the adhesive on the substrate 1 has a thin coating thickness and is over-dried). When the substrate 1 is over-dried again, the above-mentioned parts moving process can be repeated.

[0048] When the substrate 1 is no longer required to be dried, the control terminal 11 can simply turn off the hot air supply device and the first exhaust device.

[0049] In order to solve the problem that the thickness of the adhesive coating is thin during the drying process of the substrate in the existing equipment, which causes the softened part of the substrate to continue to droop downward after the substrate is softened by heat, until it falls to the bottom of the drying box, thereby causing damage to the substrate, the present invention adopts a method of cooling and supporting the drooping part of the substrate to provide a cooling environment lower than the temperature of the drying gas for the fall of the substrate, thereby achieving cooling and supporting the drooping part of the substrate, preventing the drooping part of the substrate from falling to the bottom of the drying box, thereby causing damage to the substrate.

The mirror-distributed electric sliders 60 are commonly limited and slidably connected with a liquid storage shell 61. A spring is provided between the electric slider 60 and the liquid storage shell 61. The spring is used to drive the liquid storage shell 61 to reset and slide. The liquid storage shell 61 is located above the exhaust box 17. A conical guide member 62 distributed in a rectangular array is fixed to the lower side of the liquid storage shell 61 for guiding the water droplets condensed on the lower side of the liquid storage shell 61. Two second U-shaped frames 63 distributed in a left-to-right mirror image are provided in the drying box 10, located on the right The second U-shaped frame 63 is fixedly connected to the top of the drying box 10, and the second U-shaped frame 63 on the left side is slidably connected to the top of the drying box 10.

The swinging members 64 are composed of two fixed columns and an elastic fixed net. The swinging members 64 close to the mirror-distributed second U-shaped frame 63 are respectively rotatably matched with the two, and a connecting member 65 is rotatably connected between two adjacent swinging members 64.

[0054] like Fig. 9 and Fig.10As shown, the stretching assembly includes a fourth U-shaped frame 80 fixedly connected to the top of the drying box 10, the lower side of the fourth U-shaped frame 80 is rotatably connected to the second gear 81, the top of the drying box 10 is limitedly slidably connected to the first rack frame 82 meshing with the second gear 81, the first rack frame 82 is fixedly connected to the adjacent second U-shaped frame 63, the upper side of the liquid storage shell 61 is fixedly connected to the second rack frame 83 that cooperates with the second gear 81 for transmission, and an extrusion assembly for extruding the adjacent hygroscopic member 66 is provided on the connecting member 65 on the lower side.

[0055] like Figure 9-11 As shown, the extrusion assembly includes extrusion plates 90 of the same number as the swinging member 64. The extrusion plates 90 are fixedly connected to the upper side of the swinging member 64 through elastic telescopic rods with mirror distribution.

When the extrusion frame 92 extrudes the adjacent extrusion plates 90, the extrusion plate 90 extrudes the adjacent hygroscopic member 66, so that the water droplets in the hygroscopic member 66 are squeezed out. The upper side of the extrusion frame 92 is fixedly connected to a fixing rod 93 that contacts and cooperates with the top of the drying box 10.

[0056] Before drying the substrate 1 , the staff connects the air outlet of the cold air supply device to the second air inlet pipe 51 , and then connects the air outlet of the second exhaust device to the upper side of the second exhaust pipe 67 , thereby completing the preparation work before drying the substrate 1 .

[0057] After completing the preparation work before drying the substrate 1, the staff starts the cold air supply equipment and the second exhaust equipment (simultaneously starts the hot air equipment and the first exhaust equipment mentioned in Example 1). The cold air supply equipment transports the cold air to the second air outlet box 50 through the adjacent second air inlet pipe 51, so that the cold air is ejected from the air outlet on the upper side of the second air outlet box 50. The cold air blown out from the second air outlet box 50 cooperates with the second exhaust pipe 67 to extract the gas in the drying box 10, and the humid gas in the drying box 10 is extracted in a vertical extraction manner, thereby realizing the circulation of the gas in the drying box 10.

[0058] When the substrate 1 is over-dried and softened and drooped, in order to prevent the hot air in the drying box 10 from causing the substrate 1 to continue to soften and sag, the present embodiment solves the problem of the hot air in the drying box 10 causing the substrate 1 to continue to soften and sag by cooling the softened part of the substrate 1. The details are as follows: when the substrate 1 contacts the roller 18, it drives it to rotate. During the rotation of the roller 18, the power is transmitted to the first gear 6 on the first air outlet box 14 through the first gear 6 thereon, so that the first gear 6 on the first air outlet box 14 rotates. When the seal 31 is squeezed by the adjacent L-shaped frame 22 and moves, it proves that the anti-sticking member 21 moves downward and the substrate 1 is over-dried. After the spring part of the spring distance sensor adjacent to the seal 31 is squeezed, the electrical signal is transmitted to the control terminal 11, and the control terminal 11 transmits the electrical signal to the electric push rod 40, and the electric push rod 40 pushes the support frame 41 and its attached parts upward.

[0059] In the process of the support frame 41 driving its accessory parts to move upward, the adjacent blocking part 55 is also driven to move upward synchronously, thereby removing the obstruction to the adjacent first air duct 52, so that the gas in the second air outlet box 50 can enter the adjacent first air duct 52, and the first air duct 52 transports the cold air in the second air outlet box 50 to the adjacent second air duct 54 through the adjacent flexible connecting pipe, and the second air duct 54 transports the cold air to the third air outlet box 53, so that the cold air is ejected from the air outlets distributed in a linear array of the third air outlet box 53, so that the cold air passes through the support belt 43 and cools down the substrate 1, thereby preventing the substrate 1 from being continuously softened due to the influence of residual heat in the drying box 10.

[0060] The support frame 41 moves upward so that the first gear 6 on the right rotating drum 42 is engaged with the first gear 6 on the first air outlet box 14, so that the rotating drum 42 rotates. During the rotation of the rotating drum 42, the support belt 43 is driven to move, so that the support belt 43 moves around the two rotating drums 42, driving the softened part of the substrate 1 to actively move, thereby preventing the softened part of the substrate 1 from failing to move along the roller 18, resulting in the softened part of the substrate 1 being stacked.

[0061] After the softened portion of the substrate 1 is processed, the electric push rod 40 drives the accessory parts at its telescopic end to move downward and reset. During the downward movement and reset of the support frame 41, the blocking member 55 blocks the adjacent first air duct 52.

[0062] After part of the steam in the drying box 10 is extracted by the exhaust box 17 (when the hot air sprayed from the first air outlet box 14 contacts the adhesive on the substrate 1, the moisture in the adhesive is evaporated, causing steam to exist in the drying box 10), another part of the steam in the drying box 10 moves upward, and all the moisture absorbing members 66 actively absorb the steam in the drying box 10 to prevent the steam from adhering to the inner side of the drying box 10 and condensing thereon, thereby forming condensation beads, causing the drying box 10 to be humid, thereby affecting the drying of the substrate 1 (when the condensed water droplets in the drying box 10 fall downward onto the dried substrate 1, the drying of the substrate 1 will fail).

[0063] Another part of the steam in the drying box 10 contacts the bottom of the liquid storage shell 61 during the process of floating upward, and gathers on the adjacent conical guide member 62. When the amount of water droplets gathered on the conical guide member 62 reaches the amount of water falling, the water droplets gathered on the conical guide member 62 fall downward. At this time, the air supply from the first air outlet box 14 blows the water droplets falling from the conical guide member 62 to be extracted by the exhaust box 17 to complete the treatment of the water droplets.

[0064] When it is necessary to remove the water droplets on all the moisture absorbent parts 66 (regular cleaning), the control terminal 11 controls the two electric sliders 60 to drive the liquid storage shell 61 and its accessories to move to the right. When the liquid storage shell 61 drives all the fixing pins 71 to move to the right, the fixing pins 71 contact the inclined surface of the adjacent right-angled triangle on the third U-shaped frame 70, so that the fixing pins 71 drive the liquid storage shell 61 to move downward (the liquid storage shell 61 squeezes the adjacent springs during the downward movement of the two electric sliders 60).

[0065] When the fixing pin 71 moves to a point where it is no longer in contact with the adjacent right-angled triangle on the third U-shaped frame 70, the liquid storage shell 61 moves upward and resets under the action of the spring. Through the cooperation between the fixing pin 71 and the adjacent triangle on the third U-shaped frame 70, the liquid storage shell 61 drives all the conical guide members 62 to move back and forth, thereby actively shaking off the water drops on all the conical guide members 62.

[0066] After the liquid storage shell 61 drives the fixing pin 71 to move to a point where it is no longer in contact with the adjacent right-angled triangle on the third U-shaped frame 70, the second rack rack 83 meshes with the second gear 81, so that the second gear 81 drives the first rack rack 82 to move to the left during rotation (the adjacent spring is squeezed during the movement of the first rack rack 82). During the movement of the first rack rack 82 to the left, the adjacent second U-shaped frame 63 is pulled, so that all the swinging members 64 and the moisture absorbent member 66 are switched from a folded state to a laterally distributed state. During the state switching process of all the swinging members 64 and the moisture absorbent member 66 (the liquid storage shell 61 is located below all the moisture absorbent members 66), the fixing rod 93 is in contact with the top inside the drying box 10, and all the swinging members 64 and the squeezing plate 90 are stretched when the first rack rack 82 continues to move.

[0067] Taking the state in which one of the swinging members 64 is stretched and still swinging as an example, the distance between the lower side of the swinging member 64 and the drying box 10 is shortened during the stretching process, so that the telescopic portion of the elastic telescopic member 91 is squeezed, and the squeezing frame 92 squeezes the adjacent squeezing plate 90, and the squeezing plate 90 then moves downward along the adjacent swinging member 64 and squeezes the adjacent elastic telescopic rod. During the downward movement of the squeezing plate 90, the adjacent hygroscopic member 66 is squeezed, so that the water droplets adsorbed in the hygroscopic member 66 fall downward into the liquid storage shell 61, thereby completing the treatment of the hygroscopic member 66.

[0068] When the processing of the hygroscopic component 66 is completed, the two electric sliders 60 drive the liquid storage shell 61 to reset to the left side, and the second gear 81 rotates in the opposite direction under the action of the reverse movement of the second rack frame 83, so that the first rack frame 82 resets to the right side, and the first rack frame 82 drives the adjacent second U-shaped frame 63 to reset and slide to the right side, so that the fixed rod 93 gradually disengages from the upper side of the substrate 1, and the telescopic parts of the elastic telescopic component 91 are reset one after another, so that the extrusion frame 92 no longer squeezes the adjacent extrusion plate 90, and the extrusion plate 90 resets upward under the action of the adjacent elastic telescopic rod and no longer squeezes the adjacent hygroscopic component 66, and the hygroscopic component 66 resets under the action of its own characteristics, and all the swinging members 64 gradually switch from the horizontal distribution state to the folded state.

[0069] When the two electric sliders 60 drive the liquid storage shell 61 and its attached parts to move to Fig. 9 state, the processing of all the absorbent components 66 has been completed.

[0070] When it is no longer necessary to dry the substrate 1 , the staff turns off the cold air supply device, the second exhaust device, the hot air device and the first exhaust device, and processes the water droplets collected in the liquid storage shell 61 .
