TECHNICAL FIELD

[0001] The present application belongs to the technical field of coating, in particular to a coating device. BACKGROUND

[0002] The coating device is mainly used for the surface coating process production of thin film, paper and the like, which coats a layer of glue, paint or ink with specific functions on the surface of the coated substrate in roll form, and then rolls up after drying. The coating device is widely used in the industries of adhesive tape, label, medical, electronic, photovoltaic, printing, textile, leather and the like.

[0003] In the existing coating process, the coating methods mainly include extrusion coating, doctor blade coating, transfer coating and micro-concave coating; and the heating methods mainly include hot air drying, infrared heating and ultraviolet heating.

Moreover, the existing coating device has many parts and large volume, and when different coating methods are needed for coating, multiple coating devices with different coating methods need to be installed to realize this, which requires a large installation space and increases the production cost.

[0092] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified.

[0093] As shown in Figure 1 and Figure 2 The coating device provided by the embodiment of the present application comprises a rack 30, a coating head 10, a drying box 20, an unwinding mechanism 40 and a winding mechanism 50. The unwinding mechanism 40 is assembled on the rack 30 and is used to transmit the coating substrate. The coating head 10 is detachably assembled on the rack 30 and is used to coat the coating substrate transmitted by the unwinding mechanism 40. The drying box 20 is detachably assembled on the rack 30 and is used to heat and dry the coated coating substrate. The winding mechanism 50 is assembled on the rack 30 and is used to accommodate the dried coating substrate.

[0094] As an example, the rack 30 is a component that plays a supporting role in the coating device and is used to support other structures of the coating device. The rack 30 comprises a rack body 301 and a head mounting seat 302. The head mounting seat 302 is assembled on the rack body 301, and the coating head 10 is detachably assembled on the head mounting seat 302.

[0095] As an example, the unwinding mechanism 40 is a component in the coating apparatus that serves to store and transport the coating substrate; the coating substrate to be coated is placed in a whole roll on the unwinding mechanism 40 so that the unwinding mechanism 40 continuously transports the coating substrate to the coating head 10, which is beneficial for continuous processing.

[0096] As an example, the coating head 10 is a component in the coating apparatus that performs the coating function, used to apply coating material onto the coating substrate.

[0097] As an example, the drying chamber 20 is a component in the coating apparatus that plays a role in heating and drying; after being coated by the coating head 10, the coating substrate is transferred into the drying chamber 20, so that the drying chamber 20 heats, dries and cures the coating on the coating substrate.

[0098] As an example, the winding mechanism 50 is a component in the coating apparatus that serves to store the coating substrate; after the coating substrate has been coated and dried, it is transferred to the winding mechanism 50 for storage.

[0099] In the coating apparatus provided in this embodiment of the invention, the coating substrate sequentially passes through the unwinding mechanism 40, the coating head 10, the drying chamber 20, and the winding mechanism 50 to complete the entire coating process. The coating apparatus in this example is divided into several modular designs, such as the frame 30, the coating head 10, the drying chamber 20, the unwinding mechanism 40, and the winding mechanism 50. The structure is simple, which is conducive to the overall miniaturization design of the coating apparatus, reducing the overall volume to fit a smaller installation space. Moreover, the coating head 10 and the drying chamber 20 are detachably assembled on the frame 30, so that the required coating head 10 and drying chamber 20 can be replaced as needed to change the coating method or heating method, meet the customized needs of different customers, and improve the versatility of other components of the coating apparatus.

[0100] In one embodiment, such as Figure 3 , Figure 8 , Figure 10 , Figure 14 , Figure 16 , Figure 17 , Figure 18 and Figure 19As shown, the coating head 10 is any one of the extrusion coating head 1, the blade coating head 2, the transfer coating head 3, the micro-concave coating head 4, the extrusion blade coating head 5 and the extrusion transfer coating head 6. In this example, the rack 30 is provided with a mounting position shared by the plurality of coating heads 10, and the extrusion coating head 1, the blade coating head 2, the transfer coating head 3, the micro-concave coating head 4, the extrusion blade coating head 5 and the extrusion transfer coating head 6 are detachably assembled on the mounting position, realizing random switching between the extrusion coating, the blade coating, the transfer coating and the micro-concave coating. The same coating device can meet the switching of multiple coating modes, so that the corresponding coating head 10 can be matched according to the different needs of customers to meet the customization needs of customers, improve the universality of other parts of the coating device, and facilitate large-scale batch processing.

[0101] As shown in Figure 3 The extrusion coating head 1 provided by the embodiment of the application comprises a first head support seat 11, a first substrate transmission mechanism 12, a first coating transmission mechanism 13, a first coarse adjustment mechanism 14 and a first fine adjustment mechanism 15. The first head support seat 11 is detachably assembled on the rack 30. The first substrate transmission mechanism 12 is assembled on the first head support seat 11 and is used for rolling transmission of the coating substrate. The first coating transmission mechanism 13 is assembled on the first head support seat 11 and is arranged opposite to the first substrate transmission mechanism 12, and is used for coating the coating substrate on the first substrate transmission mechanism 12. The first coarse adjustment mechanism 14 is assembled on the first head support seat 11 and is connected with the first coating transmission mechanism 13, and is used for driving the first coating transmission mechanism 13 to move between a first position and a second position arranged along a first direction. The second position is arranged close to the first substrate transmission mechanism 12. The first fine adjustment mechanism 15 is assembled on the first coarse adjustment mechanism 14 and is connected with the first coating transmission mechanism 13, and is used for driving the first coating transmission mechanism 13 to move along the first direction between the second position and the first substrate transmission mechanism 12.

[0102] As an example, the first head support seat 11 is a component for supporting other structures of the extrusion coating head 1.

[0103] As an example, the first substrate transmission mechanism 12 is a component of the extrusion coating head 1 that supports and transmits the coating substrate, and is used to continuously transmit the coating substrate so that the first coating transmission mechanism 13 can continuously coat the entire coating substrate. The first substrate transmission mechanism 12 includes a second driving assembly 121 and a second driving roller 122 connected to the second driving assembly 121. The second driving assembly 121 is mounted on the first head support seat 11, and the second driving roller 122 is used to transmit the coating substrate. The second driving roller 122 is arranged opposite the first coating transmission mechanism 13 in the first direction. The coating substrate is arranged around the second driving roller 122. The second driving assembly 121 drives the second driving roller 122 to rotate, thereby driving the coating substrate on the second driving roller 122 to move and achieve the transmission of the coating substrate.

[0104] As an example, the first coating transmission mechanism 13 is a component of the extrusion coating head 1 that performs the coating function, and is used to contain the coating material and coat the coating material on the coating substrate.

[0105] As an example, the first coarse adjustment mechanism 14 is a component of the extrusion coating head 1 that coarsely adjusts the position of the first coating transmission mechanism 13, and is used to drive the first coating transmission mechanism 13 to move between a first position and a second position. The first position and the second position are arranged apart in the first direction, and the second position is close to the first substrate transmission mechanism 12. When the first coarse adjustment mechanism 14 drives the first coating transmission mechanism 13 to move to the first position, the first coating transmission mechanism 13 is away from the first substrate transmission mechanism 12, i.e., the distance between the first coating transmission mechanism 13 and the first substrate transmission mechanism 12 is increased, which facilitates the maintenance and replacement of the first coating transmission mechanism 13 and the replacement of the new coating substrate on the first substrate transmission mechanism 12. When the first coarse adjustment mechanism 14 drives the first coating transmission mechanism 13 to move to the second position, the first coating transmission mechanism 13 is close to the first substrate transmission mechanism 12, i.e., the distance between the first coating transmission mechanism 13 and the first substrate transmission mechanism 12 is reduced, so that the coating material in the first coating transmission mechanism 13 can be coated on the coating substrate.

[0106] As an example, the first fine adjustment mechanism 15 is a component of the extrusion coating head 1 that finely adjusts the position of the first coating transmission mechanism 13, and is used to drive the first coating transmission mechanism 13 to move between the second position and the first substrate transmission mechanism 12. The distance between the first position and the second position is much greater than the distance between the second position and the first substrate transmission mechanism 12. After the first coarse adjustment mechanism 14 drives the first coating transmission mechanism 13 to move to the second position, the first fine adjustment mechanism 15 drives the first coating transmission mechanism 13 to move between the second position and the first substrate transmission mechanism 12 to finely adjust the position of the first coating transmission mechanism 13, so that the coating material in the first coating transmission mechanism 13 can be coated on the coating substrate, and the coating thickness can also be controlled.

[0107] In the extrusion coater head 1 of the present example, the first coarse adjustment mechanism 14 and the first fine adjustment mechanism 15 are used in cooperation, the first coarse adjustment mechanism 14 is used to preliminarily adjust the position of the first paint transmission mechanism 13, so that the coarse positioning of the first paint transmission mechanism 13 can be quickly realized, and then the first fine adjustment mechanism 15 is used to further adjust the position of the first paint transmission mechanism 13, so that the fine positioning of the first paint transmission mechanism 13 is realized. The positioning accuracy of the first paint transmission mechanism 13 is ensured, and the adjustment speed is improved. By adjusting the distance between the first paint transmission mechanism 13 and the first substrate transmission mechanism 12, the distance between the first paint transmission mechanism 13 and the coated substrate on the first substrate transmission mechanism 12 is adjusted, so that the coated substrate of different thicknesses can be coated, and the coating thickness of the coated substrate can be changed, thereby expanding the application range of the extrusion coater head 1.

The elbow clamp 141 includes a rotating handle 1411 hinged to the first head support seat 11 and a stepped shaft 1412 penetrating the first head support seat 11. The rotating handle 1411 is used to drive the stepped shaft 1412 to move in a first direction. The stepped shaft 1412 is sequentially sleeved with the first fixing assembly, the first elastic member 144, the connecting block 145, and the second fixing assembly. The connecting block 145 is connected with the first paint transmission mechanism 13.

[0109] In the present example, the stepped shaft 1412 is arranged in the first direction. The rotating handle 1411 is rotated to be parallel to the first direction in the length direction, drives the stepped shaft 1412 to move in the first direction, so that the connecting block 145 compresses the first elastic member 144 to move away from the first substrate transmission mechanism 12, thereby driving the first paint transmission mechanism 13 to move to a first position. The rotating handle 1411 is rotated to be perpendicular to the first direction in the length direction, so that the compression force of the first elastic member 144 is reduced, and the first elastic member 144 is relaxed to drive the connecting block 145 to move to the first substrate transmission mechanism 12, thereby driving the first paint transmission mechanism 13 to move to a second position.

[0114] Preferably, the connecting groove 1454 is a U-shaped groove, and the opening direction of the U-shaped groove is perpendicular to the first direction, so as to facilitate the assembly of the stepped shaft 1412 and the connecting groove 1454.

[0115] In an embodiment, as shown in Figure 5 and Figure 6 The first fine adjustment mechanism 15 comprises a differential head assembly 151, a baffle 152 and an adjusting shaft 153; the baffle 152 is connected with the connecting block 145, the differential head assembly 151 is sleeved on the baffle 152 and the connecting block 145, the first end of the adjusting shaft 153 is sleeved in the connecting block 145 and connected with the differential head assembly 151, and the other end of the adjusting shaft 153 is threadedly connected with the first head support 11; the differential head assembly 151 is used to drive the adjusting shaft 153 to move in the first direction.

[0116] In the example, the differential head assembly 151 is rotated to drive the adjusting shaft 153 to move in the first direction, so as to drive the baffle 152 and the connecting block 145 to move together in the first direction, and the first paint conveying mechanism 13 connected with the connecting block 145 moves between the second position and the first base material conveying mechanism 12; the first fine adjustment mechanism 15 converts the rotary adjustment into translation in the first direction, and the position of the first paint conveying mechanism 13 can be accurately adjusted by the differential head assembly 151, which is conducive to accurately controlling the coating thickness and ensuring the coating quality.

[0117] In the embodiment, as shown in Figure 5As shown, the differential head assembly 151 comprises a first differential head sleeve 1511 and a first differential head spindle 1512 connected with the first differential head sleeve 1511; the first differential head sleeve 1511 is arranged on the baffle 152 and the connecting block 145, and the first differential head spindle 1512 is connected with the adjusting shaft 153; rotating the first differential head sleeve 1511 can drive the first differential head spindle 1512 to move in the first direction, so that the adjusting shaft 153 moves in the first direction together with the first differential head spindle 1512.

In the example, when the first sliding block 1410 moves to abut against the limiting piece 1420 in the direction close to the first base material transfer mechanism 12, the first sliding block 1410 stops moving, thereby limiting the limit position of the movement of the first sliding block 1410, i.e. limiting the minimum distance between the first coating transfer mechanism 13 and the first base material transfer mechanism 12, avoiding the collision between the first coating transfer mechanism 13 and the first base material transfer mechanism 12 during adjustment, and preventing the damage to the first coating transfer mechanism 13, the first base material transfer mechanism 12 and the coated base material.

[0169] In an embodiment, as shown in the figure, Figure 10As shown, the transfer coating head 3 also includes a third scraper mechanism 35; the third scraper mechanism 35 is mounted on the third head support 31 and is arranged opposite to the first coating mechanism 36; the third paint transfer mechanism 33, the third scraper mechanism 35 and the third substrate transfer mechanism 32 are arranged sequentially along the rotation direction of the first coating mechanism 36.

By driving the third doctor blade mechanism 35 closer to or further away from the first coating mechanism 36, the seventh adjustment mechanism 34 changes the distance between the third doctor blade mechanism 35 and the first coating mechanism 36, thereby adjusting the thickness of the coating on the first coating mechanism 36. This allows for changes in the coating thickness on the substrate, enabling coating of substrates with different thicknesses and coating of different thicknesses on the same substrate, thus expanding the applicability of the transfer coating head 3.

[0174] The seventh regulating mechanism 34 has the same structure as the first regulating mechanism 24, and will not be described in detail here.

In the present example, the second coating roller 361 is a rigid roller, and the second coating roller 361 has a certain hardness; the third driving roller 322 is a flexible roller, and the third driving roller 322 has a certain flexibility, so as to facilitate the second coating roller 361 to coat the coating material on the coating substrate on the third driving roller 322.

[0178] The third driving assembly 362, the fourth driving assembly 321 and the second driving assembly 121 have the same structure, and thus will not be described herein.

The fourth head support base 41 is detachably assembled on the rack 30. The fourth coating transmission mechanism 43 is assembled on the fourth head support base 41 and is used for transmitting coating. The fourth substrate transmission mechanism 42 is assembled on the fourth head support base 41 and comprises a first driving roll 422, a first driving assembly 421 and a first guide roll assembly 423. The first driving assembly 421 is connected with the first driving roll 422 and is used for driving the first driving roll 422 to roll to transmit coating substrate. The first guide roll assembly 423 is arranged between the first driving roll 422 and the gravure roll 44 and is used for pressing the coating substrate transmitted by the first driving roll 422 on the gravure roll 44. The gravure roll 44 is assembled on the fourth head support base 41. The surface of the gravure roll 44 is provided with a micro-concave groove 441 penetrating along the axial direction thereof. The gravure roll 44 is used for rolling coating to the coating substrate on the first driving roll 422 or the coating substrate on the first guide roll assembly 423. The third adjusting mechanism 45 is assembled on the fourth head support base 41, is connected with the fourth substrate transmission mechanism 42 and is used for driving the fourth substrate transmission mechanism 42 to approach or move away from the gravure roll 44.

[0182] As an example, the fourth head support base 41 is a component on the micro-concave coating head 4 for supporting other structures of the micro-concave coating head 4.

[0183] As an example, the fourth coating transmission mechanism 43 is a component on the micro-concave coating head 4 for storing and transmitting coating. The fourth coating transmission mechanism 43 is used for containing coating and transmitting the coating to the gravure roll 44.

[0184] As an example, the gravure roll 44 is a component on the micro-concave coating head 4 for coating. The micro-concave coating head 4 further comprises a fifth driving assembly 46 assembled on the fourth head support base 41. The fifth driving assembly 46 drives the gravure roll 44 to rotate and roll around the central axis thereof, so that the gravure roll 44 rolls the coating transmitted by the fourth coating transmission mechanism 43 to the coating substrate on the fourth substrate transmission mechanism 42 to realize coating.

[0185] As an example, the fourth substrate conveying mechanism 42 is a component on the micro-concave coating head 4 that supports and conveys the coating substrate, and is used to continuously convey the coating substrate so that the gravure roller 44 continuously coats the entire coating substrate. The fourth substrate conveying mechanism 42 is mounted on the fourth head support base 41 and includes a first driving roller 422, a first driving assembly 421, and a first guide roller assembly 423. The first driving assembly 421 is connected to the first driving roller 422 and is used to drive the first driving roller 422 to roll to convey the coating substrate. The first guide roller assembly 423 is disposed between the first driving roller 422 and the gravure roller 44 and is used to press the coating substrate conveyed by the first driving roller 422 against the gravure roller 44.

[0186] In the present example, as a preferred embodiment, the coating substrate is wound around the first driving roller 422, and the gravure roller 44 abuts against the coating substrate on the first driving roller 422 to achieve coating of the coating substrate on the first driving roller 422 by the gravure roller 44. In this design, the coating substrate is conveyed in a simple manner, which is convenient to operate. As another preferred embodiment, the coating substrate is wound around the first driving roller 422 and the first guide roller assembly 423. The first guide roller assembly 423 presses the coating substrate against the gravure roller 44 so that the coating substrate abuts against the gravure roller 44, and the first driving roller 422 assists in conveying the coating substrate to achieve coating of the coating substrate on the first guide roller assembly 423 by the gravure roller 44. In this design, the conveying path of the coating substrate is as long as possible in a small space, which makes the overall structure of the micro-concave coating head 4 more compact and is conducive to reducing the installation space required by the micro-concave coating head 4.

[0187] As an example, the third adjusting mechanism 45 is a component on the fourth head support base 41 that adjusts the position of the fourth substrate conveying mechanism 42, and is used to drive the fourth substrate conveying mechanism 42 to move closer to or farther away from the gravure roller 44, so as to adjust the distance between the fourth substrate conveying mechanism 42 and the gravure roller 44, and enable the micro-concave coating head 4 to switch between the two coating substrate conveying modes described above.

[0188] In the micro-gravure coater head 4 of the present example, when only the first driving roller 422 is used to transport the coated substrate, the third adjusting mechanism 45 drives the fourth substrate transport mechanism 42 to move close to the gravure roller 44, so that the coated substrate on the first driving roller 422 abuts against the gravure roller 44 to achieve coating; when the first driving roller 422 and the first guide roller assembly 423 are used to jointly transport the coated substrate, the third adjusting mechanism 45 drives the fourth substrate transport mechanism 42 to move away from the gravure roller 44, so that the first driving roller 422 is separated from the gravure roller 44 and the coated substrate on the first guide roller assembly 423 abuts against the gravure roller 44 to achieve coating; the micro-gravure coater head 4 of the present application realizes the switching of the two kinds of coating substrate running modes by the cooperation of the third adjusting mechanism 45 and the fourth substrate transport mechanism 42, and the user can select according to the own needs, so that the overall structure of the micro-gravure coater head 4 is more compact, and the installation space required by the micro-gravure coater head 4 is reduced.

[0220] As an example, the sixth head support seat 61 is a component for supporting other structures of the squeeze transfer coating head 6.

[0221] As an example, the sixth substrate transmission mechanism 62 is a component of the squeeze transfer coating head 6 that supports and transmits the coating substrate, and is used to continuously transmit the coating substrate so that the first coating roller 66 continuously coats the entire coating substrate. The sixth substrate transmission mechanism 62 has the same structure as the third substrate transmission mechanism 32, and will not be described again here.

[0223] As an example, as shown in FIG. 6, the second cartridge 633 is fixed on the second mounting seat 631, and the coating substrate is wound on the driven roller, i.e. only the sixth substrate transmission mechanism 62 transmits the coating substrate, the position of the sixth substrate transmission mechanism 62 is adjusted by the sixth adjustment mechanism, so that the first coating roller 66 abuts against the coating substrate on the driven roller, and the first coating roller 66 rolls, first passes through the second cartridge 633, so that the second cartridge 633 transmits the coating material to the first coating roller 66, and then passes through the coating substrate on the driven roller, to coat the coating material on the coating substrate, to realize transfer coating.

[0224] As an example, as shown in FIG. 6, the second cartridge 633 is fixed on the second mounting seat 631, and the coating substrate is wound on the driven roller, i.e. only the sixth substrate transmission mechanism 62 transmits the coating substrate, the position of the sixth substrate transmission mechanism 62 is adjusted by the sixth adjustment mechanism, so that the first coating roller 66 abuts against the coating substrate on the driven roller, and the first coating roller 66 rolls, first passes through the second cartridge 633, so that the second cartridge 633 transmits the coating material to the first coating roller 66, and then passes through the coating substrate on the driven roller, to coat the coating material on the coating substrate, to realize transfer coating. Figure 18

[0225] ​​The extrusion transfer coating head 6 of the example is provided with the second installation seat 631, and the second extrusion die 632 and the second material box 633 are selectively and detachably fixed on the second installation seat 631; when the second extrusion die 632 is fixed on the second installation seat 631, the second extrusion die 632 coats the coating material on the coating substrate on the first coating roller 66 to realize the extrusion coating; when the second material box 633 is fixed on the second installation seat 631, the sixth substrate conveying mechanism 62 is adjusted to abut against the first coating roller 66 through the sixth adjusting mechanism, the second material box 633 first conveys the coating material to the first coating roller 66, and then the coating material is coated on the coating substrate on the sixth substrate conveying mechanism 62 through the first coating roller 66 to realize the transfer coating; thus, in the example, the extrusion coating and the transfer coating can be switched by switching the second extrusion die 632 and the second material box 633, so that one extrusion transfer coating head 6 can realize two coating modes, without the need to set two coating devices to realize different coating modes, which is simple and fast in operation and reduces the production cost, and thus can be applied to smaller installation space.

[0226] In an embodiment, as shown in FIG. 6, the sixth adjusting mechanism includes a third adjusting assembly 67 and a fourth adjusting assembly 68. Figure 18 The third adjusting assembly 67 is assembled on the sixth head support seat 61 and connected with the sixth substrate conveying mechanism 62, and is used to drive the sixth substrate conveying mechanism 62 to move along the first direction so that the sixth substrate conveying mechanism 62 approaches or moves away from the first coating roller 66; the fourth adjusting assembly 68 is assembled on the sixth head support seat 61 and connected with the first coating roller 66, and is used to drive the first coating roller 66 to move along the first direction so that the first coating roller 66 approaches or moves away from the sixth substrate conveying mechanism 62.

[0227] In the example, the sixth substrate conveying mechanism 62 and the first coating roller 66 are spaced apart along the first direction; the third adjusting assembly 67 is used to drive the sixth substrate conveying mechanism 62 to move along the first direction to preliminarily adjust the distance between the sixth substrate conveying mechanism 62 and the first coating roller 66, and the distance between the sixth substrate conveying mechanism 62 and the first coating roller 66 is coarsely positioned; and then the fourth adjusting assembly 68 is used to drive the first coating roller 66 to move along the first direction to accurately adjust the distance between the sixth substrate conveying mechanism 62 and the first coating roller 66, and the distance between the sixth substrate conveying mechanism 62 and the first coating roller 66 is accurately positioned; thus, the adjusting speed is ensured while the adjusting accuracy is improved, which is beneficial to quickly and accurately adjusting the distance between the sixth substrate conveying mechanism 62 and the first coating roller 66.

[0228] In the example, the third adjusting assembly 67 has the same structure as the first adjusting assembly 37, and details are not described herein.

[0229] In this example, the fourth adjustment component 68 has the same structure as the second adjustment component 38, and will not be described again here.

[0230] In one embodiment, such as Figure 18 As shown, the extrusion transfer coating head 6 also includes a ninth adjustment mechanism 610. The ninth adjustment mechanism 610 is mounted on the sixth head support 61 and connected to the second mounting base 631, used to move the second mounting base 631 closer to or away from the first coating roller 66. In this example, the ninth adjustment mechanism 610 moves the second mounting base 631 closer to or away from the first coating roller 66, which can adjust the position of the sixth paint transfer mechanism 63. In transfer coating, it ensures that the paint in the second material box 633 can be transferred to the first coating roller 66. In extrusion coating, by adjusting the distance between the second extrusion die 632 and the first coating roller 66, the distance between the second extrusion die 632 and the coating substrate on the first coating roller 66 can be adjusted, thereby enabling coating of substrates of different thicknesses and changing the coating thickness on the coating substrate.

[0231] In one embodiment, such as Figure 18 As shown, the ninth adjustment mechanism 610 includes a fourth coarse adjustment mechanism 64 and a fourth fine adjustment mechanism 65. The fourth coarse adjustment mechanism 64 is mounted on the sixth head support 61 and connected to the second mounting base 631, and is used to drive the second mounting base 631 to move between a seventh position and an eighth position set along the first direction. The eighth position is located close to the first coating roller 66. The fourth fine adjustment mechanism 65 is mounted on the fourth coarse adjustment mechanism 64 and connected to the second mounting base 631, and is used to drive the second mounting base 631 to move between the eighth position and the first coating roller 66 along the first direction.

[0232] In this example, the fourth coarse adjustment mechanism 64 and the fourth fine adjustment mechanism 65 are used in combination. First, the fourth coarse adjustment mechanism 64 is used to make preliminary adjustments to the position of the sixth paint transfer mechanism 63, which can quickly achieve the coarse positioning of the sixth paint transfer mechanism 63. Then, the fourth fine adjustment mechanism 65 is used to further adjust the position of the sixth paint transfer mechanism 63, which achieves the fine positioning of the sixth paint transfer mechanism 63. This improves the adjustment speed while ensuring the positioning accuracy of the sixth paint transfer mechanism 63.

[0233] In this example, the fourth coarse adjustment mechanism 64 has the same structure as the first coarse adjustment mechanism 14, and will not be described again here.

[0234] In this example, the fourth fine-tuning mechanism 65 has the same structure as the first fine-tuning mechanism 15, and will not be described again here.

[0235] In one embodiment, such as Figure 18As shown, the squeeze transfer coating head 6 further comprises a fourth scraper mechanism 69; the fourth scraper mechanism 69 is assembled on the sixth head support base 61 and is arranged opposite to the first coating roller 66; the sixth coating material transmission mechanism 63, the fourth scraper mechanism 69 and the sixth substrate transmission mechanism 62 are sequentially arranged along the rolling direction of the first coating roller 66.

[0236] In the present example, the fourth scraper mechanism 69 is a component on the squeeze transfer coating head 6 for controlling the coating thickness, which is used to scrape off the excess coating material on the coating transfer mechanism. The sixth coating material transmission mechanism 63, the fourth scraper mechanism 69 and the sixth substrate transmission mechanism 62 are sequentially arranged along the rotating direction of the first coating roller 66; that is, the first coating roller 66 first passes through the sixth coating material transmission mechanism 63 to pick up the coating material, then passes through the fourth scraper mechanism 69 to make the fourth scraper mechanism 69 scrape off the excess coating material on the first coating roller 66, thereby ensuring the uniformity of the coating thickness on the first coating roller 66, and finally passes through the sixth substrate transmission mechanism 62 to coat the coating material on the coating substrate on the sixth substrate transmission mechanism 62, thereby ensuring the coating quality.

[0237] In the present example, the fourth scraper mechanism 69 has the same structure as the first scraper mechanism 25, which will not be described here.

[0238] In an embodiment, as shown in Figure 18 The squeeze transfer coating head 6 further comprises a ninth adjusting mechanism 610, which is assembled on the sixth head support base 61 and is connected with the fourth scraper mechanism 69, and is used to drive the fourth scraper mechanism 69 to approach or move away from the coating mechanism.

[0239] In the present example, the ninth adjusting mechanism 610 is a component on the squeeze transfer coating head 6 for adjusting the position of the fourth scraper mechanism 69, which is used to drive the fourth scraper mechanism 69 to approach or move away from the first coating roller 66. The ninth adjusting mechanism 610 drives the fourth scraper mechanism 69 to approach or move away from the first coating roller 66, which can change the distance between the fourth scraper mechanism 69 and the first coating roller 66, thereby adjusting the thickness of the coating material on the first coating roller 66 to realize the change of the coating thickness on the coating substrate, and thus can coat the coating substrate with different thicknesses and perform coating with different thicknesses on the coating substrate, thereby expanding the application range of the squeeze transfer coating head 6.

In the example, the sixth waste groove 620 is arranged below the sixth coating material conveying mechanism 63, the first coating roller 66 and the sixth substrate conveying mechanism 62, so as to collect the excess coating material, facilitate reuse of the coating material and reduce the cost.

After the coated substrate is coated by the coating head 10, the coated substrate is conveyed to the conveying assembly 2032, and the conveying assembly 2032 is used for conveying the coated substrate in the drying box 20, so that the heating mechanism 201 heats and dries the coating on the coated substrate.

[0246] As an example, the heating mechanism 201 is a component of the drying box 20 for heating and drying the coating on the coated substrate, including a second box body 2011 and a heating oven; the second box body 2011 is a component for supporting the heating oven and providing a mounting position for the heating oven; the heating oven is detachably assembled in the second box body 2011 and used for heating and drying the coating on the coated substrate; the heating oven is any one of a hot air oven 2012, an infrared oven 2013, and an ultraviolet oven 2014.
