Description

Technical Field

[0002] The coater is mainly used for the surface coating process production of base films, papers, etc. This machine coats a roll of base material with a specific functional glue, coating, ink, etc., and then winds it up after drying. It adopts a special multi-functional coating head to achieve various forms of surface coating. The coater is equipped with a full-speed automatic film splicing mechanism for both unwinding and winding, and PLC program tension closed-loop automatic control.

[0003] With the rapid development of functional pole piece coating products and the continuous introduction of new products, the performance tests of pole pieces and coatings are becoming more and more frequent.

[0052] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0053] Hereinafter, the concept, specific structure and technical effects of the present invention will be clearly and completely described in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components alone, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined with each other without conflict.

[0054] Referring to Figures 1 to 3 As shown, the present invention discloses a multi-coating method combination device. Specifically, the device includes a first large plate 101, a second large plate 102, and a traction roller 103, an intaglio roller coating mechanism 20, a swing mechanism 30, a second coating roller 104, an inclined extrusion coating mechanism 105, a die head coating mechanism 60, and a first coating roller 106 disposed between the first large plate 101 and the second large plate 102; a control box 107 is disposed on the other side of the first large plate 101, and the first large plate 101, the second large plate 102, and the control box 107 are all disposed above a base 108; as Figure 1 、 Figure 2As shown, the swing mechanism 30 is located above the gravure roll coating mechanism 20, and the traction roll 103 is located on one side of the gravure roll coating mechanism 20. After the pole piece 40 bypasses the traction roll 103, it enters between the swing mechanism 30 and the gravure roll coating mechanism 20. In this embodiment, a transition roll 109 and a coding roll 110 are sequentially arranged below the gravure roll coating mechanism 20. The pole piece 40 passes through the transition roll 109 and the coding roll 110 in sequence, bypasses the traction roll 103, and the coding roll 110 collects the running speed of the pole piece 40. The traction roll 103 traction the pole piece 40 and controls the coating speed. The inclined extrusion coating mechanism 105 includes a second die head 1051, and the second coating roll 104 is located on one side of the second die head 1051. After the pole piece 40 passes through between the swing mechanism 30 and the gravure roll coating mechanism 20, it enters between the second coating roll 104 and the second die head 1051. The die head coating mechanism 60 includes a first die head 6021, and the first coating roll 106 is located on one side of the first die head 6021. After the pole piece 40 passes through between the second coating roll 104 and the second die head 1051, it enters between the first die head 6021 and the first coating roll 106.

[0055] Further, a first rubber pressing roller 111 and a second rubber pressing roller 112 are also arranged between the first large plate 101 and the second large plate 102. The first rubber pressing roller 111 is pressed against the traction roller 103, and the pole piece 40 passes through between the traction roller 103 and the first rubber pressing roller 111. The first rubber pressing roller 111 presses the pole piece 40 against the traction roller 103 to prevent the pole piece 40 from slipping during the traction process. Among them, the first rubber pressing roller 111 is rotatably installed at one end of a rotating connecting rod 113, and the middle of the rotating connecting rod 113 is rotatably arranged on the first large plate 101 and the second large plate 102. A pulley is installed at the other end of the rotating connecting rod 113, and the pulley is pressed against an inclined block 114. And the inclined block 114 is connected to a knob 115 through a pull rod. When the knob 115 is rotated, the inclined block 114 can be driven to move back and forth. Since the pulley is pressed against the inclined block 114, the rotating connecting rod 113 is driven to drive the first rubber pressing roller 111 to rotate, so as to adjust the pressure between the first rubber pressing roller 111 and the traction roller 103. The second rubber pressing roller 112 is pressed against the second coating roller 104, and the pole piece 40 passes through between the second coating roller 104 and the second rubber pressing roller 112. Similarly, a structure for adjusting the second rubber pressing roller 112 is also arranged below the second rubber pressing roller 112, and this structure is basically the same as the structure for adjusting below the first rubber pressing roller 111, so it will not be described in detail in this embodiment. Through the design of this structure, the pressure between the second coating roller 104 and the second rubber pressing roller 112 can be adjusted to meet the requirements of different tightness degrees during the coating of the pole piece 40. In addition, a tension adjusting roller 116, a first turning roller 117, a length recording sensor 118 and a tape connecting platform 119 are sequentially arranged between the first large plate 101 and the second large plate 102 along the conveying direction of the pole piece 40, and the tension adjusting roller 116, the first turning roller 117, the length recording sensor 118 and the tape connecting platform 119 are sequentially arranged behind the first coating roller 106. Among them, the tension adjusting roller can be used to eliminate the bad situation of uneven tension of the pole piece 40 on the first coating roller 106, the length recording sensor 118 is used to measure the length of the coating area, and the tape connecting platform 119 is used to connect the pole piece 40 when the tape is broken.

[0056] In the above embodiment, the power sources of the first coating roller 106, the second coating roller 104 and the traction roller 103 are from the same motor, and the first coating roller 106, the second coating roller 104 and the traction roller 103 are driven to move simultaneously through a belt or a timing belt. Since this structure is also relatively common in the prior art, it will not be described in detail in this embodiment.

[0057] Such as Figure 2As shown, for the inclined extrusion coating mechanism 105, the present invention provides a specific embodiment. The inclined extrusion coating mechanism 105 further includes a die head mounting plate 1052, a die head mounting bottom plate 1053, a rodless cylinder 1054, and an inclined guide rail 1055. The second die head is mounted on the die head mounting plate 1052. The die head mounting bottom plate 1053 is inclined, and two die head mounting bottom plates 1053 are respectively fixed on the first large plate and the second large plate. The inclined guide rail 1055 is arranged on the top of the die head mounting bottom plate 1053. Both ends of the die head mounting plate 1052 are slidably mounted on the inclined guide rail 1055. The rodless cylinder 1054 is fixed on the inner wall of the die head mounting bottom plate 1053. The moving end of the rodless flagpole is connected to the die head mounting plate 1052, driving the die head mounting plate 1052 and the second die head to slide on the inclined guide rail 1055, so as to adjust the distance between the second die head and the second coating roller 104, and at the same time, it is also convenient to repair or replace the second die head. The inclination angle of the second die head can be adjusted as needed. In this embodiment, the inclination angle between the second die head and the second coating roller is approximately 20 degrees.

[0058] Referring to Figures 4 to 8 As shown, for the swing mechanism 30 and the gravure roll coating mechanism 20, the present invention provides a specific embodiment. The swing mechanism 30 is located directly above the gravure roll coating mechanism 20. Specifically, as Figures 6 to 8 shown, the swing mechanism 30 includes a power device, a first substrate 301, a second substrate 302, a second rotating shaft 303, a swing rod 304, a rubber roller 305, a first fine adjustment roller 306, and a second fine adjustment roller 307. The first substrate 301 and the second substrate 302 are in a vertical state and are arranged oppositely. Both ends of the second rotating shaft 303 are rotatably mounted between the first substrate 301 and the second substrate 302. The power device is mounted on the first substrate 301 and the second substrate 302, and this power device is used to drive the second rotating shaft 303 to rotate; as Figure 8 shown, two opposite swing rods 304 are fixedly mounted on the second rotating shaft 303. The first fine adjustment roller 306 and the second fine adjustment roller 307 are both rotatably mounted between the two swing rods 304, and the first fine adjustment roller 306 and the second fine adjustment roller 307 are respectively located on both sides of the second rotating shaft 303. Both ends of the rubber roller 305 are respectively rotatably mounted on the two swing rods 304, and this rubber roller 305 is located on the other side of the first fine adjustment roller 306; as Figure 5 shown, the gravure roll coating mechanism 20 includes a gravure roll 202 for providing coating paint. This gravure roll 202 is located below the rubber roller 305. The film to be coated passes between the rubber roller 305 and the gravure roll 202, and is pressed against the gravure roll 202 by the rubber roller 305, and the paint on the gravure roll 202 is coated on the electrode sheet 40.

[0059] Driven by the power device, the rotation of the second rotating shaft 303 is controlled to drive the swing rod 304 to achieve a small swing. When the rubber roller 305 is attached to the gravure roller 202, the second fine-tuning roller 307 is separated from the pole piece 40 for coating. When the swing rod 304 swings to make the rubber roller 305 move upward and separate the rubber roller 305 from the gravure roller 202, the second fine-tuning roller 307 moves downward and contacts the pole piece 40. Through the upward movement of the rubber roller 305 and the first fine-tuning roller 306, the pole piece 40 is released. At this time, the second fine-tuning roller 307 moves downward to compensate for the length of the pole piece 40 released by the rubber roller 305 and the first fine-tuning roller 306, thereby realizing the gap coating of the pole piece 40. When the rubber roller 305 is always in contact with the gravure roller 202, continuous coating of the coating material can be achieved; and the switching between continuous coating and gap coating can be quickly realized, which is very convenient and fast to use.

[0060] For the above-mentioned power device, the present invention provides a specific embodiment, as Figure 6 、 Figure 7 shown, the power device includes a first motor 308, a first rotating shaft 309, a cam 310 and a connecting rod 311. The first motor 308 is fixed on the side wall of the first substrate 301. The first rotating shaft 309 is rotatably installed between the first substrate 301 and the second substrate 302. A speed reducer and a coupling are provided at the output end of the first motor 308. This structure is relatively common in the prior art and will not be described in detail in this embodiment. Through this structure, the connection between the output end of the first motor 308 and the first rotating shaft 309 is realized. By driving the first motor 308, the first rotating shaft 309 rotates between the first substrate 301 and the second substrate 302. As Figure 7 shown, the cam 310 is fixedly installed on the first rotating shaft 309, and a rectangular groove is provided on the cam 310. One end of the connecting rod 311 is provided with a cam follower, and the cam follower is stuck in the groove of the cam 310. The other end of the connecting rod 311 is fixedly installed on the second rotating shaft 303. Therefore, when the first rotating shaft 309 rotates, it drives the cam 310 to rotate together. Due to the cooperation between the rectangular groove on the cam 310 and the cam follower, the end of the connecting rod 311 with the cam follower can be driven to swing at intervals. Through the transmission of the connecting rod 311, the second rotating shaft 303 and the swing rod 304 swing at intervals, thereby driving the first fine-tuning roller 306, the second fine-tuning roller 307 and the rubber roller 305 to swing at intervals. In this way, by controlling the rotation of the first motor 308, the coating time can be controlled to realize the gap coating of the pole piece 40; the switching between continuous coating and gap coating can be quickly realized, which is very convenient and fast to use.

[0061] In the above embodiment, as Figure 6 、 Figure 7As shown, one end of the swing rod 304 is provided with a strip-shaped through hole, both ends of the rubber roller 305 are respectively located in the strip-shaped through holes of the two swing rods 304, and an adjusting screw 312 is further provided on the swing rod 304. One end of the adjusting screw 312 is located in the strip-shaped through hole of the swing rod 304 and is connected to the rubber roller 305. The position of the rubber roller 305 can be adjusted by the adjusting screw 312, so as to adjust the parallelism between the rubber roller 305 and the gravure roller 202, so that the coating can be applied to the pole piece 40 with high quality during coating.

[0062] On the basis of the above embodiment, in combination with Figure 6 , Figure 8 As shown, a first adjusting roller device and a second adjusting roller device are respectively provided on both sides of the swing mechanism 30. The structures of the first adjusting roller device and the second adjusting roller device are the same. The first adjusting roller device includes a first adjusting roller 313. The first adjusting roller 313 is located on one side of the rubber roller 305 and is parallel to the rubber roller 305. The second adjusting roller device includes a second adjusting roller. The second adjusting roller is located on one side of the second fine-tuning roller 307 and is parallel to the fine-tuning roller. Since the structures of the first adjusting roller 313 device and the second adjusting roller device are the same, only the structure of the first adjusting roller 313 device will be described in this embodiment. As shown in Figure 8, the first adjusting roller device further includes an adjusting roller mounting seat 314, a cushion block 315, a vertical guide rail 316, a lifting handwheel 317 and a lifting screw 318; both ends of the first adjusting roller 313 are respectively rotatably mounted on an adjusting roller mounting seat 314. One end of the lifting screw 318 is connected to the adjusting roller mounting seat 314, and the other end of the lifting screw 318 is connected to the lifting handwheel 317. The lifting handwheel 317 is rotatably mounted above the cushion block 315; the vertical guide rail 316 is fixed on the cushion block 315 along the vertical direction, and the adjusting roller mounting seat 314 is slidably arranged on the vertical guide rail 316. The first adjusting roller 313 can be raised or lowered through the cooperation of the lifting handwheel 317, the vertical guide rail 316 and the lifting screw 318. Due to the existence of the first adjusting roller 313 and the second adjusting roller, it can ensure that the compensation of the second fine-tuning roller 307 is in place.

[0063] In addition, a plurality of lifting sliders 319 are installed on the outer side walls of the first substrate 301 and the second substrate 302, and lifting guide rails 320 adapted thereto are provided on the lifting sliders 319. A lifting cylinder 321 is provided above the first substrate 301 and the second substrate 302. The first substrate 301 and the second substrate 302 are respectively connected to the cylinder rods of the corresponding lifting cylinders 321. When the coating is completed or when it is necessary to clean the gravure roller 202, the cylinder rods of the lifting cylinders 321 retract, driving the first substrate 301 and the second substrate 302 to rise, so as to facilitate the cleaning of the gravure roller 202.

[0064] For the gravure roll coating mechanism 20 described above, as Figures 9 to 13 shown, the present invention provides a specific embodiment. The gravure roll coating mechanism 20 includes a fixed frame 201, a gravure roll 202, a doctor blade 203, a doctor blade position adjusting mechanism 204, and a coating feeding mechanism. The gravure roll 202 is rotatably mounted on the fixed frame 201. One end of the gravure roll 202 is provided with a power mechanism (not shown in the figure) for driving the rotation of the gravure roll 202. This power mechanism is generally composed of a motor and a coupling, and its structure is relatively common in the prior art, so it will not be described in detail in this embodiment. Further, the doctor blade position adjusting mechanism 204 is disposed on both sides of the gravure roll 202. The doctor blade 203 is fixed to the doctor blade position adjusting mechanism 204. The position of the doctor blade 203 is adjusted through the doctor blade position adjusting mechanism 204. The two doctor blade position adjusting mechanisms respectively adjust the positions of the two doctor blades 203, so as to realize the adjustment of the distance and parallelism between the doctor blade 203 and the gravure roll 202, so as to meet the requirements of forward coating and reverse coating. Furthermore, as Figure 10 , Figure 11 shown, the coating feeding mechanism includes a material box 205. The material box 205 is disposed below the gravure roll 202. The interior of the material box 205 is composed of a coating roll wetting area 2051 and return areas 2052 located at both ends of the coating roll wetting area 2051. A partition is provided between the coating roll wetting area 2051 and the return areas 2052. The gravure roll 202 is located in the coating roll wetting area 2051. The bottom of the material box 205 is provided with a feed port 2053 and a discharge port 2054. The feed port 2053 is communicated with the coating roll wetting area 2051, and the discharge port 2054 is communicated with the return areas 2052. In addition, the coating feeding mechanism further includes a sheet metal part 206. One end of the sheet metal part 206 is hung on the material box 205, and the other end is bent towards the center of the material box 205 to form a bent end. Both sides of the bent end extend into the return areas 2052 at both ends of the material box 205.

[0065] As Figure 13 shown, when the coating enters the coating roll wetting area 2051 from the feed port 2053, it diffuses to both sides, crosses the partition between the return areas 2052 and the coating roll wetting area 2051, flows into the return areas 2052, and finally returns the coating to the storage tank through the discharge port 2054, avoiding the repeated flow of the coating liquid in the material box 205, generating sediment, affecting the coating, and at the same time realizing the recovery of the coating, achieving the purpose of saving the coating. As Figure 13As shown, the feed inlet 2053 can also be arranged on one side of the cartridge 205. When the coating enters from the feed inlet 2053, it is blocked by the bent end of the sheet metal part 206, and the coating will flow towards the bottom of the cartridge 205. After passing over the sheet metal part 206, it flows towards the upper part and both sides of the cartridge 205, which can effectively prevent the coating from depositing. During the coating process, similarly, when the coating enters the wet area 2051 of the coating roller from the feed inlet 2053, it diffuses to both sides, crosses the partition between the return area 2052 and the wet area 2051 of the coating roller, flows into the return area 2052, and finally returns the coating to the storage tank through the discharge port 2054, avoiding the repeated flow of the coating liquid in the cartridge 205, generating deposits, and affecting the coating process.

[0066] For the position adjustment mechanism of the doctor blade 203, the present invention provides a specific embodiment, as Figure 9 shown in FIGS. 10 to 11. Since a doctor blade position adjustment mechanism 204 is provided on both sides of the gravure roll 202 and their structures are exactly the same, in this embodiment, the structure of one of the doctor blade position adjustment mechanisms 204 is taken as an example for description. In this embodiment, the fixing frame 201 includes a first bottom plate 2011, a first side plate 2012 and a second side plate 2013. The first side plate 2012 and the second side plate 2013 are fixedly arranged on the first bottom plate 2011 in parallel. The gravure roll 202 is rotatably installed between the first side plate 2012 and the second side plate 2013. A translation bearing 2014 is installed on the side edge of the first bottom plate 2011. The doctor blade position adjustment mechanism 204 includes a bearing plate 2041, a first pressing plate 2042, a second pressing plate 2043, an adjustment cylinder 2044 and an adjustment bearing seat 2045. The doctor blade 203 is fixed between the first pressing plate 2042 and the second pressing plate 2043. A doctor blade liner is also arranged between the doctor blade 203 and the second pressing plate 2043. The first pressing plate 2042 is fixed on the bearing plate 2041. Adjustment bearing seats 2045 are arranged at both ends of the bearing plate 2041, and the two adjustment bearing seats 2045 are respectively installed on the first side plate 2012 and the second side plate 2013. The adjustment cylinder 2044 is rotatably installed on the fixing frame 201, and the cylinder rod of the adjustment cylinder 2044 is rotatably connected with the bearing plate 2041, as Figure 11 shown, the top end of the cylinder rod of the adjustment cylinder 2044 is rotatably connected with a transfer rod 2046, and this transfer rod 2046 is fixed on the bearing plate 2041. As Figure 9 shown, two adjustment cylinders 2044 are rotatably arranged on one side of the bearing plate 2041. By controlling the adjustment cylinders 2044, the telescopic movement of the cylinder rods of the adjustment cylinders 2044 drives the bearing plate 2041, the first pressing plate 2042, the second pressing plate 2043 and the doctor blade 203 to rotate, and the position of the doctor blade 203 close to the gravure roll 202 can be adjusted.

[0067] Further, in the above embodiments, the blade position adjusting mechanism 204 further includes an adjusting guide rail 2047, an adjusting shaft 2048, and an adjusting handwheel 2049. The adjusting guide rail 2047 is fixed to the sides of the first side plate 2012 and the second side plate 2013 in the horizontal direction. The adjusting bearing seat 2045 is slidably mounted on the adjusting guide rail 2047. One end of the adjusting shaft 2048 is connected to the adjusting bearing seat 2045, and the other end of the adjusting shaft 2048 is connected to the adjusting handwheel 2049. The adjusting handwheel 2049 is rotatably mounted on the first side plate 2012 and the second side plate 2013. With this structure, when the adjusting handwheel 2049 is rotated, the adjusting handwheel 2049 drives the adjusting shaft 2048 to rotate, and the adjusting shaft 2048 drives the adjusting bearing seat 2045 to translate on the adjusting guide rail 2047. By the cooperation of the two adjusting handwheels 2049, the distance between the blade 203 and the gravure roll 202 can be adjusted. In addition, a position display is further mounted on the adjusting shaft 2048. Mounting plates are fixed on both the first side plate 2012 and the second side plate 2013, and the adjusting handwheel 2049 is mounted on the mounting plate. The position of the blade 203 is displayed through the scale on the position display, which is convenient for adjusting the position of the blade 203.

[0068] As Figures 9 to 11As shown, adjust the air pressure of the adjusting cylinder 2044, gently press the doctor blade 203 against the gravure roll 202, and adjust the edge of the doctor blade 203 to be parallel to the gravure roll 202 by adjusting the handwheel 2049. Fix this position through the self-locking of the thread, and then retract the adjusting cylinder 2044 to disengage the doctor blade 203 from the gravure roll 202. When reverse coating needs to be achieved (that is, when the rotation direction of the gravure roll 202 is opposite to the running direction of the film), the coating enters the material box 205 from the feed port 2053. After being blocked by the sheet metal part 206, the coating flows from the bottom to the top and both sides of the material box 205. The gravure roll 202 is immersed in the coating in the material box 205. The motor drives the gravure roll 202 to rotate, and the coating adheres to the gravure roll 202. When the gravure roll 202 rotates clockwise, the retraction of the adjusting cylinder 2044 on the left side of the gravure roll 202 drives the bearing plate 2041 to rotate, thereby disengaging the doctor blade 203 from the gravure roll 202. The adjusting cylinder 2044 on the right side of the gravure roll 202 extends, driving the rotation of the bearing plate 2041, pressing the doctor blade 203 against the gravure roll 202, and scraping the coating on the roll. After scraping, a uniform and thin layer of coating will remain on the gravure roll 202, and the coating is applied to the film by contacting the film. When forward coating needs to be achieved (that is, when the rotation direction of the gravure roll 202 is the same as the running direction of the film), the coating enters the material box 205 from the feed port 2053. After being blocked by the sheet metal part 206, the coating flows from the bottom to the top and both sides of the material box 205. The gravure roll 202 is immersed in the coating in the material box 205. The motor drives the gravure roll 202 to rotate, and the coating adheres to the gravure roll 202. When the gravure roll 202 rotates counterclockwise, the retraction of the adjusting cylinder 2044 on the right side of the gravure roll 202 drives the bearing plate 2041 to rotate, thereby disengaging the doctor blade 203 from the gravure roll 202. The cylinder on the left side of the gravure roll 202 extends, driving the rotation of the bearing plate 2041, pressing the doctor blade 203 against the gravure roll 202, and scraping the coating on the gravure roll 202. After scraping, a uniform and thin layer of coating will remain on the gravure roll 202, and the coating is applied to the film by contacting the film, ensuring the uniformity of coating.

[0069] As Figure 7 , Figure 14 and Figure 15As shown, a positioning mechanism 50 is further provided below the gravure roll coating mechanism 20. The positioning mechanism 50 includes a positioning base plate 501, a first baffle 502, a second baffle 503, a bottom cylinder 504, a cylinder connecting member 505, a first connecting member 506 and a second connecting member 507. The first baffle 502 and the second baffle 503 are fixed on the opposite side walls of the positioning base plate 501. The bottom cylinder 504 is rotatably installed on the lower bottom surface of the positioning base plate 501. The cylinder connecting member 505 is connected to the cylinder rod. The second connecting member 507 is fixed on the second baffle 503. One end of the first connecting member 506 is rotatably connected to the cylinder connecting member 505. The middle of the first connecting member 506 is rotatably connected to the second connecting member 507. A top pin is connected to the other end of the first connecting member 506, and the top pin passes through the second baffle 503. The top end of the top pin presses against the first bottom plate 2011 of the gravure roll coating mechanism 20, so as to adjust the overall position of the gravure roll coating mechanism 20.

[0070] Referring to Figures 16 to 19 As shown, for the die coating mechanism 60, the present invention provides a specific embodiment. The die coating mechanism 60 includes a support frame 601, a die head mechanism 602, a rotation driving mechanism 603, a lifting driving mechanism 604 and a lifting fine adjustment mechanism 605. The support frame 601 includes a first support plate 6011 and a bottom support base 6012. The first support plate 6011 is slidably installed on the bottom support base 6012 in the vertical direction. The die head mechanism 602 and the rotation driving mechanism 603 are both fixedly connected to the first support plate 6011. The die head mechanism 602 includes a first die head 6021. The rotation driving mechanism 603 is used to drive the first die head 6021 to rotate. The lifting driving mechanism 604 is arranged on the bottom support base 6012. The lifting driving mechanism 604 includes a connecting seat 6041 fixed on the first support plate 6011. The lifting driving mechanism 604 is used to drive the connecting seat 6041 and the first support plate 6011 to reciprocate in the vertical direction, so as to drive the die head mechanism 602 to reciprocate in the vertical direction. The structure of the lifting driving mechanism 604 will be further described below. As Figure 19As shown, the lifting and fine-tuning mechanism 605 includes a fine-tuning motor 6051, a fine-tuning lead screw 6052, a nut connecting seat 6053, a nut guide rail 6054, a nut slider 6055, and an adjustment block 6056. The fine-tuning motor 6051 and the nut guide rail 6054 are fixed to the bottom support seat 6012. In this embodiment, the fine-tuning motor 6051 is fixed to the first side plate (second side plate) through a first base 6057, and the nut guide rail 6054 is fixed to the first base 6057. The fine-tuning lead screw 6052 passes through the nut connecting seat 6053, and one end of the fine-tuning lead screw 6052 is connected to the motor shaft of the fine-tuning motor 6051. The nut guide rail 6054 is parallel to the fine-tuning lead screw 6052, and the nut connecting seat 6053 is slidably mounted on the nut guide rail 6054; one end of the adjustment block 6056 is rotatably connected to the connecting seat 6041. An inclined surface is provided on the adjustment block 6056. The nut slider 6055 is fixed to the nut connecting seat 6053, and the nut slider 6055 abuts against the inclined surface of the adjustment block 6056.

[0071] With this structure, when the fine-tuning motor 6051 rotates, it drives the fine-tuning lead screw 6052 to rotate, and then drives the nut connecting seat 6053 to slide on the nut guide rail 6054. During this process, since the nut slider 6055 fixed below the nut connecting seat 6053 abuts against the inclined surface of the adjustment block 6056, when there is a relative horizontal movement between the nut connecting seat 6053 and the adjustment block 6056, due to the effect of the inclined surface, a small vertical displacement will occur simultaneously. Figure 19 In the state shown, after the nut connecting seat 6053 moves to the right, it will drive the adjustment block 6056 to rotate and move downward at the same time. Then, through the cooperation of the lifting drive mechanism 604, the first support plate 6011 can be finely adjusted in the vertical direction, realizing the micro-adjustment of the lifting of the die head mechanism 602. This adjustment method has a very high precision and can adjust the height and tilt angle of the first die head 6021. Due to the presence of the lifting and fine-tuning mechanism 605, the height of the first die head 6021 can be finely adjusted, realizing the precise control of coating.

[0072] Furthermore, as Figure 16 、 Figure 17As shown, the support frame 601 further includes a second support plate 6013, and the second support plate 6013 is horizontal. The second support plate 6013 is vertically connected to the top of the first support plate 6011. The die head mechanism 602 and the rotary drive mechanism 603 are both fixedly arranged on the second support plate 6013. The bottom support base 6012 includes a second bottom plate 6014, a first side vertical plate 6015, and a second side vertical plate 6016. The first side vertical plate 6015 and the second vertical plate are vertically and fixedly arranged on the second bottom plate 6014 in parallel. The first support plate 6011 is slidably installed vertically between the first side vertical plate 6015 and the second side vertical plate 6016. To improve strength, a plurality of support tubes 6017 are also fixedly arranged between the first side vertical plate 6015 and the second side vertical plate 6016. In this embodiment, die head lifting guide rails 6018 are vertically arranged on the first side vertical plate 6015 and the second side vertical plate 6016, and sliders are arranged on the die head lifting guide rails 6018. The first support plate 6011 is fixedly connected to the sliders. In this way, the lifting movement of the first support plate 6011 in the vertical direction is realized.

[0073] For the lifting drive mechanism 604, as Figure 17 , Figure 19 shown, the present invention provides a specific embodiment. Two sets of lifting drive mechanisms 604 are provided. The two sets of lifting drive mechanisms 604 are respectively fixed on the side walls of the first side vertical plate 6015 and the second side vertical plate 6016. For the convenience of description, only the structure of the lifting drive mechanism 604 fixed on the first side vertical plate 6015 is described in this embodiment. The lifting drive mechanism 604 further includes a lifting cylinder 6042, a cylinder seat 6043, and a cylinder connecting piece 6044. The lifting cylinder 6042 is fixed on the cylinder seat 6043, and the cylinder seat 6043 is fixed on the side wall of the first side vertical plate 6015. The bottom end of the cylinder connecting piece 6044 is connected to the cylinder rod of the lifting cylinder 6042. A bayonet is arranged at the bottom of the connecting seat 6041, and the top end of the cylinder connecting piece 6044 is snapped into the bayonet of the connecting seat 6041. Driven by the lifting cylinder 6042, the die head mechanism 602 and the rotary drive mechanism 603 are lifted on the die head lifting guide rails 6018.

[0074] For the die head mechanism 602 and the rotary drive mechanism 603, as Figure 16 , Figure 17 shown, the present invention provides a specific embodiment. The die head mechanism 602 further includes a die head mounting seat 6022 and a material receiving box 6023. The die head is fixedly mounted on the die head mounting seat 6022, and the material receiving box 6023 is fixedly arranged on the die head mounting seat 6022 and is located below the die head. As Figure 17 , Figure 18As shown in the figure, the rotation drive mechanism 603 includes a rotation motor 6031, a first bearing block 6032, a second bearing block 6033, a first transmission shaft 6034, and a second transmission shaft 6035. The first bearing block 6032 and the second bearing block 6033 are both fixed on the second support plate 6013. Bearings are provided inside both the first bearing block 6032 and the second bearing block 6033. One end of the first transmission shaft 6034 is fixed on the die head mounting seat 6022, and the other end of the first transmission shaft 6034 extends into the first bearing block 6032. One end of the second transmission shaft 6035 is fixed on the die head mounting seat 6022, and the other end of the second transmission shaft 6035 passes through the second bearing block 6033 and is connected to the motor shaft of the rotation motor 6031. The rotation motor 6031 is fixed on the second bearing block 6033. In addition, a speed reducer is connected to the output shaft of the rotation motor 6031 and is connected to the second transmission shaft 6035 through the speed reducer. Therefore, driven by the rotation motor 6031, the die head mounting seat 6022 and the die head rotate together.

[0075] In addition, a locking block 606 is provided on the side wall of the second bearing block 6033. The locking block 606 has a through hole for the second transmission shaft 6035 to pass through, and a locking handle for locking the second transmission shaft 6035 is also provided on the locking block 606. Sensor bases 607 are fixedly installed at the tops of the first side vertical plate 6015 and the second side vertical plate 6016. A sensor 608 and a dial indicator 609 are installed on the sensor bases 607. An induction block 611 is correspondingly installed on the second support plate 6013. The other end of the first transmission shaft 6034 passes through the first bearing block 6032, and an encoder 610 is installed on the top end of the first transmission shaft 6034. Through the cooperation of the sensor, the induction block, and the dial indicator, the precise adjustment of the tilt angle of the die head can be achieved. After the tilt angle is determined, the second transmission shaft 6035 is locked by the locking block 606 to make the die head in a fixed tilt state, so as to control the longitudinal thickness of the coating during coating. Due to the presence of the encoder 610, the deflection angle of the die head is fed back to the rotation motor 6031 by the encoder 610 to achieve the correction of the deflection angle. Therefore, the control of the deflection angle of the die head is very precise.

[0076] In the above embodiments, when the inclined extrusion coating mechanism 105 is used alone, that is, the first die head 6021 is separated from the first coating roller 106, the first rubber pressing roller 111 on the traction roller 103 is separated from the traction roller 103, the gravure roll coating mechanism 20 is located below the swing mechanism 30, the gravure roll coating mechanism 20 does not participate in coating, and the second rubber pressing roller 112 below the second coating roller 104 presses on the second coating roller 104. Through the control of the inclined extrusion coating mechanism 105, intermittent coating or continuous coating of extrusion coating can be achieved. Similarly, when the die head coating mechanism 60 is used alone, that is, when the first die head 6021 is used alone, the second die head 1051 is separated from the second coating roller 104, the first rubber pressing roller 111 on the traction roller 103 is separated from the traction roller 103, the gravure roll coating mechanism 20 is located below the swing rod mechanism 30, that is, the gravure roll coating mechanism 20 does not participate in coating, and the second rubber pressing roller 112 below the second coating roller 104 presses on the second coating roller 104. Through the control of the die head coating mechanism 60, intermittent coating or continuous coating of extrusion coating can be achieved. When the first die head 6021 is a double-chamber die head, double-layer continuous coating or double-layer intermittent coating can be achieved.

[0077] When the gravure roll coating mechanism 20 is required as the undercoat, simultaneous coating of the inclined extrusion coating mechanism 105 and the gravure roll coating mechanism 20 can be achieved. Specifically, the first die head 6021 is separated from the first coating roller 106. At this time, the first rubber pressing roller 111 on the traction roller 103 presses on the traction roller 103, and the second rubber pressing roller 112 below the second die head 1051 is in a separated state, that is, the second rubber pressing roller 112 does not press on the second coating roller 104. Another solution is that the inclined extrusion coating mechanism 105 is separated, the first die head 6021 starts coating, and the other structural states remain unchanged. The gravure roll coating mechanism 20 as the undercoat can achieve continuous coating or intermittent coating, and only the coating method of the inclined extrusion coating mechanism 105 needs to be switched to continuous coating or intermittent coating.

[0078] When the inclined extrusion coating mechanism 105 is used as the undercoat, multi-layer coating can be achieved. Specifically, as follows, the first rubber pressing roller 111 on the traction roller 103 bounces off, the swing mechanism 30 on the gravure roll coating mechanism 20 is in the upper position, that is, the gravure roll coating mechanism 20 does not participate in coating, and the second rubber pressing roller 112 below the inclined extrusion coating mechanism 105 presses on the second coating roller 104. At this time, intermittent coating or continuous coating of multi-layer coating can be achieved.

[0079] The above is a specific description of the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments.
