[0002] A forward and reverse coater is a type of coater, which usually has scrapers on both sides of the coating roller. The forward and reverse rotation of the coating roller is used to determine which scraper is used for scraping and coating, thereby flexibly adjusting the coating thickness and reducing the frequency of shutdown for debugging.

DETAILED DESCRIPTION

[0030] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0031] like Figures 1 to 5 As shown, the present invention provides a coating machine with an easily detachable reverse head, comprising a machine body 1, a coating mechanism 2, a positive head mechanism 3 and a reverse head mechanism 4 all arranged on the machine body 1, the coating mechanism 2 is used to coat the film material, the positive head mechanism 3 and the reverse head mechanism 4 are respectively located on both sides of the coating mechanism 2, the positive head mechanism 3 and the reverse head mechanism 4 are both used to scrape off excess coating on the film material, one side of the machine body 1 is provided with a mounting groove 11, the mounting groove 11 is detachably installed with a limiting mechanism 5, the reverse head mechanism 4 is detachably installed in the mounting groove 11, and the limiting mechanism 5 is used to stop the reverse head mechanism 4 to prevent the reverse head mechanism 4 from detaching from the mounting groove 11.

[0032] In actual applications, when it is necessary to install the reverse head mechanism 4, it is only necessary to slide the reverse head mechanism 4 into the body 1 along the installation groove 11, and then assemble the limiting mechanism 5 into the installation groove 11, and use the limiting mechanism 5 to press against the reverse head mechanism 4 in the installation groove 11 to achieve the positioning and assembly of the reverse head mechanism 4, thereby ensuring that the reverse head mechanism 4 does not shift in the installation groove 11; when it is necessary to disassemble the reverse head mechanism 4, it is only necessary to remove the limiting mechanism 5 first, and then the reverse head mechanism 4 can slide along the installation groove 11 and detach from the body 1.

[0033] The body 1 of the present invention is preferably composed of two vertical plates and a connecting column arranged between the two vertical plates. Both vertical plates are provided with mounting grooves 11. The reverse head mechanism 4 is slidably arranged in the mounting grooves 11 and is located between the two vertical plates. Limit blocks 51 (not shown in the figure) can be respectively arranged on both sides of the reverse head mechanism 4 to prevent the reverse head mechanism 4 from moving along the length direction of the connecting column. The limiting mechanism 5 is then used to limit the reverse head mechanism 4 to prevent the reverse head mechanism 4 from moving along the length direction of the mounting grooves 11, thereby achieving the positioning and installation of the reverse head mechanism 4.

[0034] In this embodiment, the mounting groove 11 includes a guide portion 12, a clamping portion 13 and a limiting portion 14 connected thereto, the widths of the guide portion 12, the clamping portion 13 and the limiting portion 14 decrease successively, the reverse head mechanism 4 is installed on the limiting portion 14 and the clamping portion 13, the top and / or bottom of the guide portion 12 has a guide slope 15, the guide slope 15 is used to guide the reverse head mechanism 4 into the mounting groove 11; the limiting mechanism 5 is detachably installed on the clamping portion 13.

[0035] That is, the reverse head mechanism 4 will enter the guide part 12 under the guidance of the guiding slope 15, and then slide along the clamping part 13 until the head end of the reverse head mechanism 4 enters the limiting part 14 to complete the assembly. At this time, part of the reverse head mechanism 4 is still located in the clamping part 13, and it is pushed against and limited by the limiting mechanism 5 to complete the final assembly.

[0036] Specifically, the side wall of the clamping portion 13 is provided with a screw hole 16, and the limiting mechanism 5 is fixed to the screw hole 16 by the screw 6. The clamping portion 13 and the limiting mechanism 5 are fixed by the screw 6, so that the limiting mechanism 5 is easy to disassemble and assemble, and it is ensured that the reverse head mechanism 4 does not need other structures such as screws for secondary fixation, thereby ensuring the disassembly and assembly efficiency.

[0037] Specifically, the limiting mechanism 5 includes a limiting block 51, a pressure sensor 52 and a trigger 53. The limiting block 51 is detachably mounted on the mounting groove 11 and is located inside the mounting groove 11. The limiting mechanism 5 operates as follows:

[0038] The pressure value applied to the limit block 51 by the reverse head mechanism 4 is sensed by the pressure sensor 52;

[0039] When the pressure value sensed by the pressure sensor 52 changes, the trigger 53 is activated and the displacement of the reverse head mechanism 4 is obtained through the trigger 53;

[0040] Combined with the pressure value change and the displacement, it is determined whether the reverse head mechanism 4 is loose. If so, the coating machine is controlled to gradually slow down until it stops working. Otherwise, the coating machine is controlled to continue working.

[0041] In actual use, the pressure sensor 52 is installed on the limit block 51 and contacts the reverse head mechanism 4. The trigger 53 includes a displacement sensor. The trigger 53 is installed in the mounting groove 11. The trigger 53 has a movable end. The movable end of the trigger 53 contacts the reverse head mechanism 4. This embodiment only shows the position direction of the trigger 53.

[0042] After the reverse head mechanism 4 and the limit mechanism 5 are installed, the contact state between the pressure sensor 52 and the reverse head mechanism 4 is fixed, that is, the pressure from the reverse head mechanism 4 on the pressure sensor 52 is basically unchanged. When the reverse head mechanism 4 is in action, the force generated by its vibration will cause a certain degree of interference with the pressure sensor 52. At this time, a range can be set for the pressure sensed by the pressure sensor 52 according to the actual test situation. The pressure value changes within this range are all normal and do not need to be dealt with. When the measured pressure is not within this range, if it is too large, the reverse head mechanism 4 is subjected to external thrust and squeezes the pressure sensor 52. At this time, it is necessary to sense the time for which the excessive pressure is maintained. If it exceeds the preset time t (which can be set to 5-10 seconds), it is necessary to stop the machine for processing. If it is too small, it indicates that the screw 6 connecting the limit mechanism 5 and the clamping part 13 has a certain degree of Loosening causes the limit mechanism 5 to loosen and no longer stably press the reverse head mechanism 4. At this time, the trigger 53 needs to be started: because the reverse head mechanism 4 can still be kept stable when the looseness is small, and only when the looseness reaches a certain value, the limit mechanism 5 will have a certain distance from the reverse head mechanism 4 to allow the reverse head mechanism 4 to move back and forth. At this time, the displacement of the reverse head mechanism 4 measured by the trigger 53 can be known, that is, when the reverse head mechanism 4 is displaced by the preset distance relative to the trigger 53, the limit mechanism 5 is loosened more seriously. At this time, it is necessary to gradually reduce the working speed of the present invention until the present invention stops, and then the limit mechanism 5 can be re-fixed or the screws 6 / fixing mechanism can be replaced.

[0043] That is, the present invention can self-check whether the reverse head mechanism 4 is loose, and when it is loose, the machine can be stopped in time for maintenance by staff, thereby ensuring the coating quality and effect of the present invention.

[0044] Specifically, the limit block 51 has a screw hole 54, and the screw hole 16 is connected to the screw hole 54 and fixed by a screw 6; the screw hole 54 has a first power terminal 55, and the first power terminal 55 is connected to the pressure sensor 52; the screw hole 16 has a second power terminal 17, and the second power terminal 17 is electrically connected to the first power terminal 55 through the screw 6.

[0045] The screw 6 may have a screw head 61 (made of metal), an insulating section 62 and a conductive section 63 which are arranged in sequence, wherein the conductive section 63 is also made of metal, and the first power terminal 55 and the second power terminal 17 are electrically connected via the conductive section 63, so that the limit mechanism 5 can only allow the pressure sensor 52 to be energized after the installation is completed; when there is no signal from the pressure sensor 52, the present invention will not be started, thereby ensuring safety.

[0046] Only the conductive section 63 of the screw 6 has threads, and the insulating section 62 can be made of insulating material or formed of a metal material after insulation treatment, in order to isolate the electricity between the screw head 61 and the conductive section 63, thereby ensuring the safety of the staff.

[0047] In this embodiment, the reverse head mechanism 4 includes a mounting seat 41, a transverse movement module 42, a knife seat 43, a scraper 44 and an angle adjustment module 45. The mounting seat 41 is installed in the mounting groove 11, the transverse movement module 42 is installed on the mounting seat 41, and the scraper 44 is installed on the knife seat 43. The transverse movement module 42 is used to drive the knife seat 43 to move back and forth to drive the scraper 44 to approach or move away from the coating module. The angle adjustment module 45 is used to drive the scraper 44 to rotate to fine-tune the distance of the scraper 44 relative to the coating module.

[0048] That is, the reverse head mechanism 4 scrapes away excess paint on the coating mechanism 2 through the scraper 44. In addition to being driven by the transverse movement module 42 to move closer to or farther away from the coating mechanism 2, it can also be driven by the angle adjustment module 45 to flip over, thereby changing the posture of the scraper 44 relative to the coating mechanism 2, thereby achieving the effect of fine-tuning the distance between the scraper 44 and the coating mechanism 2.

[0049] Specifically, the knife seat 43 includes a rotating seat 431, a knife mounting portion 432, a connecting portion 433 and a control portion 434. The transverse module 42 drives and connects the rotating seat 431. The scraper 44 is installed on one side of the knife mounting portion 432. The connecting portion 433 is arranged on the other side of the knife mounting portion 432. The bottom of the connecting portion 433 is rotatably connected to the rotating seat 431, and the connecting portion 433 and the control portion 434 are perpendicular to each other.

[0050] The angle adjustment module 45 includes an angle adjustment cylinder 451, a guide column 452 and a guide sleeve 453. The angle adjustment cylinder 451 is rotatably installed on the control part 434. The piston rod of the angle adjustment cylinder 451 is rotatably connected to the rotating seat 431. The guide column 452 is rotatably set on the rotating seat 431. The guide sleeve 453 is set at one end of the control part 434 away from the connecting part 433, and the guide sleeve 453 is sleeved on the guide column 452.

[0051] The connecting part 433 and the control part 434 form a structure similar to the shape of "7". The control part 434 is driven by the angle adjustment cylinder 451 to flip, and the guide column 452 and the guide sleeve 453 cooperate to achieve the guiding and supporting effects, so that the tool holder 43 remains stable when flipping.

[0052] That is, when the piston rod of the angle adjustment cylinder 451 retracts, the distance between the control part 434 and the rotating seat 431 will be reduced, thereby driving the blade mounting part 432 to flip upward, achieving the effect of flipping the scraper 44 upward. In this way, the movement of the piston of the angle adjustment cylinder 451 can be converted into the flip angle of the scraper 44. The change in the flip angle of the scraper 44 will inevitably cause the horizontal distance between the scraper 44 and the coating to change, thereby achieving the effect of high-precision adjustment of the horizontal distance.

[0053] In this embodiment, the coating mechanism 2 includes a coating roller 21, a pressure roller 22, a pressure roller lifting module 23, a guide roller 24 and a turning roller module 25. The coating roller 21 is rotatably arranged on the machine body 1, and the coating roller 21 is connected to a coating motor. The pressure roller lifting module 23 is used to drive the pressure roller 22 to rise and fall, and the pressure roller 22 is located directly above the coating roller 21; the guide roller 24 is used to guide the movement of the film material, and the turning roller module 25 is used to drive the guide roller 24 to flip to adjust the movement path of the film material.

[0054] In actual use, the coating motor drives the coating roller 21 to rotate, allowing the coating roller 21 to be dipped in paint in the material box (not marked in the figure) and rotate to the reverse head mechanism 4 or the positive head mechanism 3 to scrape the material, and then the scraped paint is dipped on the film material held by the pressure roller 22, thereby completing the coating action.

[0055] Specifically, the roller module 25 includes a roller cylinder 251 and a roller seat 252. The roller cylinder 251 is rotatably arranged on the machine body 1, one end of the roller seat 252 is rotatably installed on the machine body 1, the guide roller 24 is installed on the other end of the roller seat 252, and the piston rod of the roller cylinder 251 is rotatably connected to the roller seat 252.

[0056] That is, the guide roller 24 is installed on the roller seat 252, and the roller seat 252 is controlled to turn around one end of the roller seat 252 as the center by the piston rod of the roller cylinder 251 being extended and retracted, thereby adjusting the position of the guide roller 24. In actual application, each wire tube can be equipped with a tension sensor (not shown in the figure) for sensing the tension of the film material, and the guide roller 24 is controlled to turn according to the tension of the film material, as follows:

[0057] The tension of the film material held by the guide roller 24 is sensed by the tension sensor;

[0058] When the film material tension is not within a preset range, the roll-over module 25 controls the guide roller 24 to flip according to the film material tension, and the guide roller 24 flips to stretch or relax the film material, thereby changing the film material tension.

[0059] Specifically, the coating mechanism 2 further includes two guide modules 26, the guide modules 26 include a guide cylinder 261 and a guide roller 262, the two guide rollers 262 are respectively located on both sides of the pressure roller 22, the piston rod of the guide cylinder 261 is installed with a guide seat 263, and the guide roller 262 is rotatably installed on the guide seat 263;

[0060] There is a coating gap 27 between the pressure roller 22 and the coating roller 21 , and the two guide rollers 262 cooperate to adjust the angles at which the film material enters and leaves the coating gap 27 .

[0061] That is, different film materials have different required angles when entering the coating gap 27 and when leaving the coating gap 27. Based on this phenomenon, the present invention specially sets two guide modules 26, and uses the guide cylinder 261 to control the lifting of the guide roller 262 to change the angle of the film material entering / leaving the coating gap 27, so that the present invention can adjust the angle online, achieving the effect of non-stop debugging.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention is disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent changes and modifications made to the above embodiments according to the technology of the present invention are within the scope of the technical solution of the present invention without departing from the content of the technical solution of the present invention.
