Description

Technical Field

[0001] The present invention relates to the technical field of fuel cell processing devices, and in particular to a coating mechanism and carbon paper processing equipment. Background Art

[0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of water electrolysis, where hydrogen and oxygen are supplied to the anode and cathode respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, it releases electrons and reaches the cathode through an external load.

[0003] As one of the key components of hydrogen fuel cells, carbon paper plays important roles such as conductivity, load bearing and drainage, and is usually called a gas diffusion layer. In the processing of carbon paper, a coating mechanism is generally required to coat the liquid MPL (Microporous Layer) slurry on the surface of the carbon paper, and then sinter it at high temperature to complete the production of the microporous layer of the carbon paper.

[0004] In the prior art, manufacturers need to use two coating methods (blade coating and slot extrusion coating) to coat carbon paper during the experimental stage. However, in the prior art, a coating mechanism only has one coating method. In view of this, manufacturers generally equip two coating mechanisms, and the coating methods of the two coating mechanisms are different. This leads to high equipment costs and large space occupation. Summary of the invention

[0092] Embodiment 1

[0093] See also Figure 1This embodiment provides a coating mechanism, which can complete the coating of slurry on carbon paper. The coating mechanism has two modes: blade coating and slit extrusion coating. The operator can choose one of the two modes to coat the slurry on carbon paper according to actual needs.

[0094] Specifically, in this embodiment, the coating mechanism includes a frame 1 , a coating roller 3 , a blade coating module 2 and a slit extrusion coating module 4 .

[0095] The coating roller 3 is rotatably disposed on the frame 1. When the coating mechanism is working, the carbon paper passes around the coating roller 3, which not only completes the coating of the slurry on the carbon paper, but also guides and transports the carbon paper.

[0096] The scraper coating module 2 is movably disposed on the frame 1 , and the scraper coating module 2 can be close to or away from the coating roller 3 . When the scraper coating module 2 is close to the coating roller 3 , the two can surround and form a material holding area 5 .

[0097] The slit extrusion coating module 4 is movably disposed on the frame 1 , and the slit extrusion coating module 4 can be close to or away from the coating roller 3 .

[0098] When the coating mechanism provided in this embodiment is working, the operator can choose to use blade coating or slit extrusion coating as needed. If it is necessary to use blade coating to coat the carbon paper, the slit extrusion coating module 4 is controlled to be away from the coating roller 3, and the blade coating module 2 is controlled to be close to the coating roller 3 to form a material holding area 5, and the slurry is injected into the material holding area 5. The carbon paper to be coated passes through the material holding area 5, and the blade coating module 2 cooperates with the coating roller 3 to complete the coating of the slurry on the carbon paper. If it is necessary to use slit extrusion coating to coat the carbon paper, the blade coating module 2 is controlled to be away from the coating roller 3, and the slit extrusion coating module 4 is controlled to be close to the coating roller 3. The coating roller 3 and the slit extrusion coating module 4 cooperate to complete the slit coating of the slurry on the carbon paper by slit coating.

[0099] It can be understood that when the blade coating method is selected to coat the carbon paper, the slit extrusion coating module 4 is controlled to be away from the coating roller 3, so that the slit extrusion coating module 4 can be prevented from interfering with the work of the blade coating module 2. When the blade coating method is selected to coat the carbon paper, the blade coating module 2 is controlled to be away from the coating roller 3, so that the blade coating module 2 can be prevented from interfering with the work of the slit extrusion coating module 4.

[0100] Specifically, in this embodiment, the slurry in the material holding area 5 can be injected by using a feeding pipe 53 disposed on the frame 1 or by manual pouring.

[0101] Specifically, see Figure 1-Figure 3In this embodiment, the scraper coating module 2 includes a material trough component 21 and a scraper 22.

[0102] The trough assembly 21 is movably arranged on the frame 1, and can be close to or away from the coating roller 3. When the trough assembly 21 is close to the coating roller 3, a feeding gap 51 for carbon paper to pass through can be formed between the two.

[0103] The scraper 22 is movably arranged on the frame 1 and is spaced apart from the upper side of the coating roller 3, and the scraper 22 can be close to or away from the coating roller 3. The scraper 22 is spaced apart from the upper side of the coating roller 3 to form a material gap 52 therebetween.

[0104] The material trough assembly 21 , the coating roller 3 and the scraper 22 can be jointly arranged to form a material holding area 5 , and a material feeding gap 51 exists between the material trough assembly 21 and the coating roller 3 .

[0105] Specifically, when the slit coating method is selected, the trough assembly 21 and the scraper 22 are controlled to be away from the coating roller 3. When the scraper coating method is selected, the trough assembly 21 and the scraper 22 are controlled to be close to the coating roller 3. At this time, the trough assembly 21, the coating roller 3 and the scraper 22 are jointly surrounded to form the material holding area 5. There is a feeding gap 51 between the trough assembly 21 and the coating roller 3. The uncoated carbon paper enters the material holding area 5 from the feeding gap 51, and passes through the material holding area 5 through the material gap 52 between the coating roller 3 and the scraper 22. When the carbon paper passes through the material gap 52, the scraper 22 and the coating roller 3 cooperate to complete the coating of the slurry on the carbon paper.

[0106] Specifically, in this embodiment, in order to achieve the scraper 22 approaching or moving away from the coating roller 3, the scraper coating module 2 further includes a scraper lifting drive assembly 23, the scraper lifting drive assembly 23 is arranged on the frame 1, the scraper 22 is connected to the output end of the scraper lifting drive assembly 23, and the scraper lifting drive assembly 23 can drive the scraper 22 to approach or move away from the coating roller 3. The scraper lifting drive assembly 23 can quickly adjust the scraper 22 to a preset position. For example, the scraper lifting drive assembly 23 can quickly adjust the scraper 22 to be close to the coating roller 3, so that a material passing gap 52 is quickly formed between the two.

[0107] More specifically, the scraper lifting drive assembly 23 includes a lifting drive member 231 and a lifting block 232 .

[0108] The lifting drive member 231 is disposed on the frame 1. Optionally, the lifting drive member 231 is a cylinder.

[0109] The lifting block 232 is slidably disposed on the frame 1 along the movement direction of the scraper. The output end of the lifting drive member 231 is connected to the lifting block 232 , and the scraper 22 is disposed on the lifting block 232 .

[0110] Optionally, the scraper moves in the direction of gravity. It is understandable that the direction of gravity is the vertical direction.

[0111] Specifically, there are two scraper lifting drive assemblies 23 , and the two scraper lifting drive assemblies 23 are respectively located at two ends of the scraper 22 .

[0112] More specifically, a guide rail extending along the movement direction of the scraper is arranged on the frame 1, and a slider is fixedly arranged on the lifting block 232, and the slider can be slidably arranged on the guide rail.

[0113] More specifically, see Figure 2 and Figure 3 In this embodiment, in order to enable the trough component 21 to approach or move away from the coating roller 3, the scraper coating module 2 also includes a transverse movement component 24.

[0114] Specifically, see Figure 4 and Figure 5 The transverse movement assembly 24 includes an adjusting screw 241 and an adjusting member 242. The adjusting screw 241 is threadedly connected to the frame 1, and the adjusting member 242 is threadedly connected to the adjusting screw 241 to form a screw nut structure.

[0115] Optionally, the adjusting screw 241 may be driven to rotate by manual tightening, or a motor for controlling the rotation of the adjusting screw 241 may be provided on the frame 1 .

[0116] Optionally, in this embodiment, the scraper 22 has two blades, and the two blades are arranged at intervals along the outer peripheral surface of the scraper 22. The scraper coating module 2 also includes a scraper drive 221, which is arranged on the frame 1 and can drive the scraper 22 to rotate around its own axis to achieve blade switching and increase the service life of the scraper 22.

[0117] Furthermore, when the type of slurry changes, the feeding angle of the trough assembly 21 also needs to be adaptively adjusted to avoid bubbles in the slurry falling on the carbon paper due to an inappropriate feeding angle. Therefore, in this embodiment, the installation angle of the trough assembly 21 on the frame 1 is adjustable to adjust the feeding angle of the feeding gap 51.

[0118] Specifically, see Figure 6 and Figure 7 In this embodiment, the trough assembly 21 includes a trough plate 211 and a mounting plate 212 .

[0119] Specifically, in terms of the actual use orientation of the coating mechanism, the upward surface of the material trough plate 211 (the surface is tilted upward) is the bottom surface of the material holding area 5 .

[0120] A mounting plate 212 is provided at both ends of the trough plate 211, and the mounting plate 212 is mounted on the frame 1 with an adjustable angle, so as to adjust the mounting angle of the trough assembly 21. The mounting plate 212, the trough plate 211, the coating roller 3 and the scraper 22 are jointly arranged to form a material holding area 5.

[0121] There is a feeding gap 51 between the lower end of the trough plate 211 and the coating roller 3 .

[0122] The mounting plate 212 is mounted on the adjusting member 242 .

[0123] When the inclination angle of the trough plate 211 needs to be adjusted, the installation angle of the installation plate 212 on the frame 1 is adjusted to adjust the inclination angle of the trough plate 211, thereby adjusting the feeding angle of the slurry in the material holding area 5.

[0124] Further, in order to adjust the installation angle of the mounting plate 212 on the rack 1, see Figure 7 and Figure 8 In this embodiment, a group of mounting holes is provided on the mounting plate 212 .

[0125] The mounting hole group includes a first hole 2121, a first connecting member, a second hole 2122 and a second connecting member.

[0126] The first connecting member can pass through the first hole 2121 and be connected to the frame 1 .

[0127] The second hole 2122 is a strip-shaped hole, and the second hole 2122 extends along the circumference of a circle with the center of the first hole 2121 as the center. The second connecting member can pass through the second hole 2122 and be connected to the frame 1.

[0128] That is, the second hole 2122 is an arc-shaped strip hole, and the arc-shaped strip hole can prevent the second connecting member from interfering with the second hole 2122 when the angle is adjusted.

[0129] Preferably, the first hole 2121 is a round hole for easy processing and manufacturing. Of course, in other embodiments, the first hole 2121 can also be an elliptical hole, a bar hole or a square hole, as long as it can ensure that the first connecting member passes through the first hole 2121, and no excessive restrictions are made here.

[0130] Preferably, the number of the first hole 2121 is one, the number of the second holes 2122 is three, and the three second holes 2122 are distributed on a circle with the center of the first hole 2121 as the center. Such an arrangement can ensure that when the installation angle of the mounting plate 212 on the rack 1 is adjusted into place, the first connecting member and the second connecting member jointly fix the mounting plate 212 stably on the rack 1, thereby preventing the mounting plate 212 from moving in position due to unstable connection.

[0131] Of course, in other embodiments, the number of the second holes 2122 can be set to be greater as needed.

[0132] Optionally, the first connecting member and the second connecting member are both bolts.

[0133] Specifically, the frame 1 is provided with a first connection hole corresponding to the first hole 2121, and the frame 1 is also provided with a second connection hole corresponding to the second hole 2122. Both the first connection hole and the second connection hole are internal thread holes adapted to bolts.

[0134] More specifically, in this embodiment, the first connecting hole and the second connecting hole are both arranged on the adjusting member 242, that is, the installation angle of the mounting plate 212 relative to the adjusting member 242 is adjusted by the mounting hole group, so as to achieve the adjustment of the installation angle of the mounting plate 212 on the rack 1.

[0135] Specifically, see Figure 6 and Figure 7 In this embodiment, the material trough assembly 21 also includes two material trough baffles 213, and the two material trough baffles 213 are arranged at intervals along the spacing direction between the two mounting plates 212, and the distance between the two material trough baffles 213 is adjustable. The two material trough baffles 213, the material trough plate 211, the coating roller 3 and the scraper 22 are jointly arranged to form a material holding area 5.

[0136] Specifically, Figure 7 As an example, the spacing direction between the two mounting plates 212 is Figure 7 The length direction of the trough plate is shown (this direction is parallel to the axial direction of the coating roller 3).

[0137] The arrangement of the trough baffle 213 can ensure that the slurry in the material holding area 5 is stably located in the material holding area 5. Each trough baffle 213 is adjustable in position on the trough plate 211 along the spacing direction between the two mounting plates 212. In this arrangement, the width dimension between the two trough baffles 213 can be adjusted, and thus the width dimension of the material holding area 5 can be adjusted (the width direction of the material holding area 5 is Figure 7 The length direction of the trough plate shown in the figure) can ultimately adjust the slurry coating width on the carbon paper.

[0138] Specifically, the trough baffle 213 includes a trough baffle body 2131 , a trough baffle body fixing frame 2132 and a first locking member 2133 .

[0139] The trough baffle body 2131 is fixedly disposed on the trough baffle body fixing frame 2132 .

[0140] The trough baffle body fixing frame 2132 includes an upper frame 21321 and a lower frame 21322 which are connected to each other. The trough baffle body 2131 is fixedly arranged on the lower surface of the upper frame 21321. The lower surface of the trough baffle body 2131 and the upper surface of the lower frame 21322 are relatively spaced apart. The trough plate 211 is clamped between the lower surface of the trough baffle body 2131 and the upper surface of the lower frame 21322. The first locking piece 2133 is threaded through the lower frame 21322 and then pressed against the lower surface of the trough plate 211.

[0141] That is, there is a clamping plate gap between the lower surface of the trough baffle body 2131 and the upper surface of the lower frame 21322, and the size of the clamping plate gap is the same as the thickness of the trough plate 211.

[0142] Such an arrangement not only realizes the adjustment of the installation position of the trough baffle 213 , but also avoids the problem that the trough plate 211 cannot be used normally due to the opening of holes in the trough plate 211 .

[0143] Optionally, the first locking member 2133 is a bolt, and a five-star handle is provided at one end of the first locking member 2133 away from the trough baffle body 2131 to facilitate the operator to screw the first locking member 2133.

[0144] Specifically, see Figure 7 , along the first direction, the mounting position of the trough plate 211 on the mounting plate 212 is adjustable to adjust the gap between the trough plate 211 and the coating roller 3. That is, the size of the feeding gap 51 is adjusted. The first direction is parallel to the direction in which the trough plate 211 approaches or moves away from the coating roller 3.

[0145] Specifically, Figure 7 Taking the direction shown as an example, the first direction is Figure 7 The width direction of the trough plate is shown (this direction is inclined compared to the horizontal direction).

[0146] It is understandable that when the type of slurry changes, it is necessary to adaptively adjust the installation angle of the trough plate 211 relative to the frame 1. When the angle of the trough plate 211 changes, the size of the feeding gap 51 will also change. If the size of the feeding gap 51 is too large, leakage may occur at the feeding gap 51; if the size of the feeding gap 51 is too small, it may affect the transportation of carbon paper to the material holding area 5. Therefore, when the angle of the trough plate 211 changes, it is necessary to adaptively adjust the gap between the trough plate 211 and the coating roller 3, that is, adaptively adjust the size of the feeding gap 51.

[0147] Specifically, in order to achieve the adjustment of the installation position of the trough plate 211 on the mounting plate 212 along the first direction, the scraper coating module 2 also includes a trough plate position adjustment component 25, and each mounting plate 212 is provided with a trough plate position adjustment component 25. Along the spacing direction between the two mounting plates 212, the two ends of the trough plate 211 are respectively installed on a trough plate position adjustment component 25. The trough plate position adjustment component 25 is used to adjust the installation position of the trough plate 211 so that the trough plate 211 can be adjusted in a direction close to or away from the coating roller 3, that is, the installation position of the trough plate 211 can be adjusted along the first direction.

[0148] Further specifically, the trough plate position adjustment assembly 25 includes a trough plate position adjustment plate 251 and a second locking member 252. The trough plate position adjustment plate 251 is fixedly connected to the mounting plate 212. There is a trough plate installation gap between the trough plate position adjustment plate 251 and the mounting plate 212. The end of the trough plate 211 is placed in the trough plate installation gap. The second locking member 252 passes through the trough plate position adjustment plate 251 and abuts against the trough plate 211, thereby clamping the end of the trough plate 211 in the trough plate installation gap.

[0149] Optionally, the number of the second locking members 252 is two.

[0150] Specifically, the slot plate position adjustment plate 251 includes a bottom plate 2511 and a side plate 2512 that are vertically connected, and the bottom plate 2511 and the side plate 2512 are both arranged along the first direction (i.e. Figure 7 The trough plate shown extends in the width direction).

[0151] The mounting plate 212 is fixedly connected to the inner surface of the side plate 2512 , and there is a slot plate mounting gap between the lower surface of the mounting plate 212 and the upper surface of the bottom plate 2511 . The second locking member 252 passes through the bottom plate 2511 and abuts against the slot plate 211 .

[0152] Optionally, the second locking member 252 is a screw, and a five-star handle is provided at one end of the second locking member 252 away from the mounting plate 212 .

[0153] Further, see Figure 9-11 In order to adjust the coating thickness of the slurry on the carbon paper, the blade coating module 2 further includes a blade coating thickness adjustment component 26. The blade coating thickness adjustment component 26 can adjust the size of the feed gap 52, thereby adjusting the coating thickness of the slurry on the carbon paper.

[0154] Specifically, the blade coating thickness adjustment assembly 26 includes a third adjustment member 261 and a fourth adjustment member 262 .

[0155] The third adjusting member 261 is fixedly disposed on the lower surface of the lifting block 232. The lower surface of the third adjusting member 261 is provided with a third inclined surface 2611 inclined relative to the lifting direction of the lifting block 232. The fourth adjusting member 262 is arranged along a direction perpendicular to the lifting direction of the lifting block 232 (i.e. Fig. 9 The fourth adjusting member 262 is movably arranged on the frame 1 in the second direction shown in the figure. The lower surface of the fourth adjusting member 262 is provided with a fourth inclined surface 2621 inclined relative to the lifting direction of the lifting block 232. The third inclined surface 2611 can descend to at least partially fit with the fourth inclined surface 2621.

[0156] It is understandable that when the scraper lifting drive assembly 23 drives the scraper 22 to move downward toward the coating roller 3, the scraper lifting drive assembly 23 stops operating after the third inclined surface 2611 moves to contact the fourth inclined surface 2621 of the fourth adjusting member 262. If it is necessary to adjust the size of the feeding gap 52, that is, if it is necessary to adjust the slurry coating thickness on the carbon paper, the fourth adjusting member 262 is controlled to slide on the fourth inclined surface 2621 in a direction perpendicular to the lifting direction of the lifting block 232, so that the height of the block formed by the third adjusting member 261 and the fourth adjusting member 262 can be adjusted, and then the feeding gap 52 between the scraper 22 and the coating roller 3 can be finely adjusted, thereby achieving the adjustment of the slurry coating thickness on the carbon paper.

[0157] Further, in order to realize the reciprocating movement of the fourth adjusting member 262 in a direction perpendicular to the lifting direction of the lifting block 232, see Figure 3 The blade coating thickness adjustment assembly 26 also includes a second adjustment member driving structure.

[0158] Specifically, the second adjustment member driving structure includes a fourth adjustment member driving member 2631 and a second screw rod 2632, the fourth adjustment member driving member 2631 is installed on the frame 1, the second screw rod 2632 extends along the second direction, the fourth adjustment member 262 is threaded through the second screw rod 2632, and the fourth adjustment member 262 and the second screw rod 2632 are screw rod nut structures. The output shaft of the fourth adjustment member driving member 2631 is connected to the second screw rod 2632 through a coupling, and can drive the second screw rod 2632 to rotate around its own axis.

[0159] When the fourth adjusting member driving member 2631 drives the second screw rod 2632 to rotate, the fourth adjusting member 262 reciprocates along the second screw rod 2632 to adjust the material passing gap 52 .

[0160] Furthermore, in order to reduce the movement resistance of the fourth adjusting member 262, the fourth adjusting member 262 is provided with a plurality of rotating rollers arranged in sequence along a direction perpendicular to the lifting direction of the lifting block 232. The existence of the rotating rollers makes the friction between the third adjusting member 261 and the fourth adjusting member 262 rolling friction, and the rolling friction resistance is small, which facilitates the adjustment of the feed gap 52.

[0161] For example, Fig.10 and Fig.11 Taking the shown orientation as an example, when the gap size of the feed gap 52 needs to be increased, the fourth adjusting member 262 is controlled to move to the left; when the gap size of the feed gap 52 needs to be decreased, the fourth adjusting member 262 is controlled to move to the right.

[0162] Specifically, in this embodiment, the installation position of the trough assembly 21 on the frame 1 is adjustable to be close to or away from the coating roller 3. With this arrangement, after the coating roller 3 and the scraper 22 are adjusted to a certain position, the position of the trough assembly 21 can be quickly adjusted to a certain position to quickly form the material holding area 5.

[0163] Specifically, in this embodiment, Figure 2 Take the direction shown as an example, along Figure 2 In the third direction, the installation position of the trough assembly 21 on the frame 1 is adjustable to be close to or away from the coating roller 3. The third direction is a horizontal direction and is perpendicular to the axis direction of the coating roller 3.

[0164] Specifically, see Figure 2 The third direction and the second direction are perpendicular to each other, and both are horizontal directions. The second direction is parallel to the axis of the coating roller 3. The second direction is parallel to the axis direction of the coating roller 3.

[0165] Further, see Figure 1 , Fig.12 and Fig.13 In this embodiment, the slit extrusion coating module 4 includes a slit extrusion die 41 and a slit extrusion die driving assembly 42 .

[0166] The slot extrusion die head 41 is movably disposed on the frame 1 .

[0167] The slot extrusion die driving assembly 42 is disposed on the frame 1 and connected to the slot extrusion die 41 to drive the slot extrusion die 41 to move closer to or away from the coating roller 3 .

[0168] Specifically, when the slurry needs to be coated by a doctor blade coating method, the slot extrusion die head driving component 42 controls the slot extrusion die head 41 to be away from the coating roller 3. When the slurry needs to be coated by a slot extrusion coating method, the slot extrusion die head driving component 42 controls the slot extrusion die head 41 to be close to the coating roller 3.

[0169] Specifically, see Figure 14-16 In this embodiment, the slot extrusion die driving assembly 42 includes a slot extrusion die driving member 421 and a first moving block 422 .

[0170] The slot extrusion die driving component 421 is disposed on the frame 1 .

[0171] The first moving block 422 is slidably disposed on the frame 1 , the output end of the slot extrusion die driving member 421 is connected to the first moving block 422 , and the slot extrusion die 41 is fixedly disposed on the first moving block 422 .

[0172] Specifically, the first moving block 422 is movably disposed on the frame 1 through a guide rail slider assembly, the guide rail of the guide rail slider assembly is fixedly disposed on the frame 1 , and the slider of the guide rail slider assembly is fixedly disposed on the first moving block 422 .

[0173] Furthermore, a driving die plate 423 is fixedly disposed on the first moving block 422 , and the slit extrusion die 41 is fixedly disposed on the driving die plate 423 .

[0174] Furthermore, the slit extrusion coating module 4 further includes a slit extrusion coating thickness adjustment component 43 to adjust the coating thickness of the slit extrusion coating module 4 .

[0175] The slot extrusion coating thickness adjusting assembly 43 includes a first adjusting member 431 and a second adjusting member 432 .

[0176] The first adjusting member 431 is disposed on the slot extrusion die driving assembly 42 , and a first adjusting inclined surface 4311 is disposed on the first adjusting member 431 .

[0177] The second adjusting member 432 is movably arranged on the frame 1, and a second adjusting bevel 4321 is arranged on the second adjusting member 432. The first adjusting bevel 4311 can move to at least partially fit with the second adjusting bevel 4321. The second adjusting member 432 can move relative to the frame 1 to change the distance between the first adjusting bevel 4311 and the coating roller 3, thereby changing the distance between the first moving block 422 and the coating roller 3, and further changing the distance between the slit extrusion die 41 and the coating roller 3, so that the coating thickness can be adjusted according to actual conditions.

[0178] Furthermore, the slit extrusion coating thickness adjustment component 43 also includes a second adjustment member driving structure 433 , and the second adjustment member driving structure 433 includes a second adjustment member driving member 4331 and a first screw rod 4332 .

[0179] The second adjusting member driving member 4331 is disposed on the frame 1 .

[0180] The first screw rod 4332 is connected to the output shaft of the second adjusting member driving member 4331 , and the second adjusting member 432 is threadedly connected to the first screw rod 4332 .

[0181] Specifically, Fig.14 and Fig.15 Taking the position shown as an example, the slot extrusion die driving member 421 drives the slot extrusion die 41 to move along the first direction (i.e., the third direction), wherein the third direction is horizontal and perpendicular to the axis of the coating roller 3. When the first adjusting member 431 and the second adjusting member 432 come into contact, the slot extrusion die 41 stops moving; then, it is confirmed whether the slot extrusion coating thickness needs to be adjusted, and if so, the second adjusting member driving member 4331 is controlled to move.

[0182] If the slit extrusion coating thickness needs to be increased, the second adjusting member driving member 4331 drives the second adjusting member 432 to move away from the coating roller 3 in the axial direction parallel to the coating roller 3, that is, Fig.14 As a reference, the second adjusting member 432 is driven to move downward, and the second adjusting member 432 can drive the first adjusting member 431 to move in a direction away from the coating roller 3 during the downward movement. If the slit extrusion coating thickness needs to be reduced, the second adjusting member driving member 4331 drives the second adjusting member 432 to approach the coating roller 3 in the axial direction parallel to the coating roller 3, thereby avoiding a space for the first adjusting member 431 to continue to approach the coating roller 3, and then the slit extrusion die head 41 is controlled to continue to move slightly toward the coating roller 3.

[0183] Specifically, Fig.14 and Fig.15 The up-down direction of the viewing angle is substantially the second direction, and the second direction is a horizontal direction and parallel to the axial direction of the coating roller 3 .

[0184] Exemplarily, the operation process of the coating mechanism provided in this embodiment is as follows:

[0185] When it is necessary to use a scraper coating method to coat the carbon paper, the slit extrusion die drive assembly 42 controls the slit extrusion die 41 to move away from the coating roller 3, and controls the material trough assembly 21 and the scraper 22 to move close to the coating roller 3. The material trough assembly 21, the coating roller 3 and the scraper 22 can be jointly surrounded to form a material holding area 5, and the coating thickness is adjusted by the scraper coating thickness adjustment assembly 26; after the carbon paper is fed into place, the slurry is injected into the material holding area 5, and the carbon paper is transported at a set speed. The scraper 22 and the coating roller 3 cooperate to achieve the coating of the slurry on the carbon paper.

[0186] When the carbon paper needs to be coated by slit extrusion, the material trough assembly 21 and the scraper 22 are controlled to be away from the coating roller 3, the slit extrusion die head driving assembly 42 controls the slit extrusion die head 41 to be close to the coating roller 3, and the distance between the slit extrusion die head 41 and the coating roller 3 is controlled by the slit extrusion coating thickness adjustment assembly 43, and the slit extrusion die head 41 sprays the slurry onto the carbon paper on the coating roller 3. In this process, the spraying thickness can be controlled by adjusting the distance between the slit extrusion die head 41 and the coating roller 3 and coordinating the feeding speed of the feeding system.

[0187] In the coating mechanism provided in this embodiment, the blade coating module 2 and the slit extrusion coating module 4 share a coating roller 3, which has a compact structure, occupies a small space, and can fully reduce the equipment cost.

[0188] Embodiment 2

[0189] See also Fig.17 , this embodiment provides a carbon paper processing device.

[0190] The carbon paper processing equipment comprises an unwinding mechanism 10 , the coating mechanism in the first embodiment, a drying mechanism 20 and a winding mechanism 30 .

[0193] The carbon paper processing equipment provided in this embodiment can complete the coating, drying and winding of the carbon paper 100. And its coating mechanism can use different coating methods to coat the carbon paper 100 as needed. If it is necessary to use a blade coating method to coat the carbon paper, the slit extrusion coating module 4 is controlled to be away from the coating roller 3, and the blade coating module 2 is controlled to be close to the coating roller 3 to form a material holding area, and the slurry is injected into the material holding area 5. The carbon paper to be coated passes through the material holding area 5, and the blade coating module 2 cooperates with the coating roller 3 to complete the coating of the slurry on the carbon paper. If it is necessary to use a slit extrusion coating method to coat the carbon paper, the blade coating module 2 is controlled to be away from the coating roller 3, and the slit extrusion coating module 4 is controlled to be close to the coating roller 3. The coating roller 3 and the slit extrusion coating module 4 cooperate to complete the slit coating of the slurry on the carbon paper by slit coating.

[0194] Specifically, see Fig.18 In this embodiment, the unwinding mechanism 10 includes an unwinding mechanism mounting frame 101 and an unwinding roller 102 .

[0195] The unwinding roller 102 is rotatably disposed on the unwinding mechanism mounting frame 101 , and the unwinding roller 102 can reciprocate along its own axis.

[0196] The unwinding roller 102 can reciprocate along its own axis. With this arrangement, when the carbon paper 100 is deflected during the unwinding process, the unwinding roller 102 reciprocates along its own axis to correct the deviation of the carbon paper 100.

[0197] Optionally, the unwinding roller 102 is an air-inflating shaft.

[0198] Specifically, see Figure 18-Figure 20 A fixed plate 1011 is provided on the unwinding mechanism mounting frame 101, and a linear guide rail is provided on the fixed plate 1011. The unwinding mechanism 10 also includes a sliding mounting plate 1012, and a slider that slides with the linear guide rail is fixedly provided on the sliding mounting plate 1012.

[0199] An unwinding roller driving member 1013 is disposed on the sliding mounting plate 1012 , and an output end of the unwinding roller driving member 1013 is fixedly connected to the unwinding roller 102 , thereby driving the unwinding roller 102 to rotate around its own axis.

[0200] Furthermore, a reel-unwinding roller driving component mounting frame 1014 is provided on the sliding mounting plate 1012 , and the reel-unwinding roller driving component 1013 is provided on the reel-unwinding roller driving component mounting frame 1014 .

[0201] A deviation correction propeller 1015 is also provided on the fixed plate 1011 , one end of the deviation correction propeller 1015 is fixedly mounted on the fixed plate 1011 , and the other end is connected to the unwinding roller driving component mounting frame 1014 .

[0202] The rolled carbon paper is mounted on the unwinding roller 102, and the unwinding roller driving member 1013 drives the unwinding roller 102 to rotate around its own axis, thereby unwinding the carbon paper 100. Optionally, the unwinding roller driving member 1013 is a servo motor.

[0203] The unwinding mechanism mounting frame 101 is also provided with a guide roller 103 which is arranged parallel to the unwinding roller 102 and spaced apart. At the same time, a correction sensor 104 is also provided on the unwinding mechanism mounting frame 101. The carbon paper 100 passes through the correction sensor 104 after passing through the guide roller 103. When the correction sensor 104 detects that the carbon paper 100 deviates, the correction propeller 1015 pushes the unwinding roller driving component mounting frame 1014, thereby driving the unwinding roller 102 to move along its own axis to complete the correction of the carbon paper 100.

[0204] Specifically, the drying mechanism 20 belongs to the prior art and will not be described in detail here.

[0205] Specifically, see Figure 21-23The winding mechanism 30 includes a winding mechanism mounting frame 301 , a traction assembly 302 and a carbon paper tightening assembly 303 .

[0206] The traction assembly 302 is disposed on the winding mechanism mounting frame 301 and is used to traction the carbon paper 100.

[0207] Specifically, in this embodiment, the traction assembly 302 includes a plurality of traction rollers 3021 sequentially arranged at intervals along the traction path.

[0208] The carbon paper tightening assembly 303 is disposed on the winding mechanism mounting frame 301 and is used to tighten the carbon paper 100 pulled and transported by the pulling assembly 302 .

[0209] The provision of the carbon paper tightening assembly 303 can ensure that the carbon paper 100 is always kept in a tightened state during the conveying process, thereby ensuring that the carbon paper 100 is smoothly rolled up.

[0210] Specifically, the carbon paper tightening assembly 303 includes a floating roller 3031 , and the floating roller 3031 can be floatingly mounted on the winding mechanism mounting frame 301 .

[0211] Furthermore, the carbon paper tightening assembly 303 further includes a swing shaft 3035 and two swing plates 3032 that are relatively spaced apart, the swing shaft 3035 is fixedly mounted on the winding mechanism mounting frame 301, and the upper end of the swing plate 3032 is rotatably mounted on the swing shaft 3035. Specifically, a bearing is provided between the swing plate 3032 and the swing shaft 3035 to ensure smooth rotation of the swing plate 3032.

[0212] The two ends of the floating roller 3031 are rotatably arranged at the lower ends of the two swinging plates 3032. Two pushers 3033 are also arranged on the winding mechanism mounting frame 301. The pushers 3033 are arranged one by one with the swinging plates 3032. The pushers 3033 can push the corresponding swinging plates 3032 to rotate around the swinging shaft 3035. At the same time, in order to prevent the swinging plates 3032 from swinging too much, stoppers 3034 are arranged on both sides of each swinging plate 3032. The stoppers 3034 are fixedly arranged on the winding mechanism mounting frame 301.

[0213] Optionally, the pushing member 3033 is a cylinder.

[0214] Furthermore, the winding mechanism 30 further includes a coating unwinding assembly 305 , which can unwind the coating on the tensioned carbon paper 100 to protect the carbon paper 100 .

[0215] The winding mechanism 30 further includes a winding shaft assembly 306 , and the winding shaft assembly 306 can be used to wind up the carbon paper 100 covered with the coating.

[0216] Exemplarily, in this embodiment, the working process of the carbon paper processing equipment is as follows:

[0217] The carbon paper 100 is unwound and rectified by the unwinding mechanism 10, and then moves to the coating roller 3 along with the coating traction roller 6;

[0218] The coating mechanism coats the carbon paper 100;

[0219] After coating, the carbon paper 100 enters the drying mechanism 20 for drying;

[0220] After drying, the carbon paper 100 enters the winding mechanism 30, and the correction unit 304 of the winding mechanism 30 corrects the carbon paper 100, and the correction method is path correction;

[0221] Subsequently, under the traction of the traction assembly 302 of the winding mechanism 30, the carbon paper 100 moves to the floating roller 3031, and the floating roller 3031 controls the tension of the carbon paper 100; the traction assembly 302 continues to transport the carbon paper 100, and the coating unwinding assembly 305 unwinds the protective film, and the protective film is compounded with the coated carbon paper 100 before the carbon paper 100 is wound up, and finally the winding shaft assembly 306 completes the winding of the finished product.
