Description

Technical Field

[0002] The existing primer coating machine needs to adjust different scraper positions and postures according to the different slurries and film materials. The postures that need to be adjusted include scraper angle, scraper position angle and yaw angle. The best coating effect can be achieved under the best posture, and the existing scraper posture is adjusted manually by adjusting four hand wheels.

Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. For example, the fixed connection / installation can be connected by screws, bolts and other accessories, or it can be directly connected by welding, bonding and other methods. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0033] Reference Figure 1 The embodiment of the utility model includes a primer, which includes a micro-gravure roller 2 and wall panels 1 arranged at both ends of the micro-gravure roller 2, and the scraper reset device is installed on the wall panel 1. The scraper reset device can adjust the position of the scraper 31 so that the position relationship between the scraper 31 and the micro-gravure roller 2 is in an optimal state to achieve the best coating effect, and when the slurry and film material are replaced, the scraper reset device can quickly reset the scraper 31 to the best memorized position, thereby improving work efficiency.

[0034] Specifically, in the embodiments of the present invention, referring to Figure 2The scraper resetting device includes a scraper assembly 3, a scraper displacement assembly 4, a scraper rotation assembly 5, a scraper lifting assembly 6 and a PLC controller. The scraper assembly 3 includes a scraper 31 and a scraper fixing seat 32, and the scraper 31 is fixedly installed on the scraper fixing seat 32; the scraper displacement assembly 4 can drive the scraper 31 to move in the horizontal direction to adjust the position of the scraper 31, thereby adjusting the distance between the scraper 31 and the micro-gravure roller 2; the scraper rotation assembly 5 can drive the scraper displacement assembly 4 and the scraper assembly 3 to rotate as a whole to adjust the angle of the scraper 31; the scraper lifting assembly 6 can drive the scraper rotation assembly 5, the scraper displacement assembly 4 and the scraper assembly 3 to rise and fall synchronously as a whole to adjust the height of the scraper 31; by adjusting the height and angle of the scraper 31 and the distance between the scraper 31 and the micro-gravure roller 2, the scraper 31 is in the best posture to achieve the best coating effect.

[0035] In this embodiment, the power sources of the scraper displacement assembly 4, the scraper rotation assembly 5, and the scraper lifting assembly 6 are all servo motors, which are respectively marked as the first servo motor 41, the second servo motor 51 and the third servo motor 61. In this way, by using the servo motor as the power source, there is no need to manually rotate the hand wheels for adjustment compared to the prior art, thereby reducing labor intensity; the servo motor can also realize soft limit of the position of the scraper 31 to avoid interference between parts; in addition, based on the mechanical structure of the scraper resetting device, the scraper resetting device is coupled to the position of the scraper 31, and the use of a servo motor can realize electronic decoupling of the scraper 31, thereby reducing the complexity of adjusting the scraper 31.

[0036] Furthermore, the output end of the PLC controller is connected to the signal input end of the first servo motor 41, the second servo motor 51, and the third servo motor 61. The PLC controller is used to memorize the operation process of the first servo motor 41, the second servo motor 51, and the third servo motor 61. The PLC controller is used to control the operation of the first servo motor 41, the second servo motor 51, and the third servo motor 61. Specifically, for the combination of new film materials and slurries, the technician manually teaches the reset, and adjusts the posture of the scraper 31 by controlling the servo motor to achieve the best coating effect. After achieving the best effect, the rotation angle of each servo motor is recorded and stored using the PLC. When the same film material and slurry are encountered next time or the stop position of the scraper 31 changes due to other reasons. Select the stored data in the PLC, and realize the one-key reset of the scraper 31 by controlling the operation of each servo motor, thereby reducing the debugging time.

[0037] In a specific embodiment, referring to Figure 2 , Figure 3 and Figure 4There are two scraper displacement assemblies 4, and the two scraper displacement assemblies 4 are respectively connected to the two ends of the scraper 31. The scraper displacement assembly 4 includes a first servo motor 41 and a first linear transmission mechanism 42. The output shaft of the first servo motor 41 is used to drive the first linear transmission mechanism 42 to move. The two driven ends of the first linear transmission mechanism 42 are respectively hinged to the two ends of the scraper fixing seat 32. In this way, the two scraper displacement components 4 respectively drive one end of the scraper fixing seat 32 to move, that is, when the horizontal displacement of the scraper 31 needs to be adjusted, the first servo motors 41 in the two scraper displacement components 4 operate synchronously to drive the scraper 31 away from or close to the micro-gravure roller 2, and when the film material is damaged and rolled into the micro-gravure roller 2 or maintenance is required, the scraper 31 can be quickly withdrawn with one key, so that the scraper 31 is quickly moved away from the micro-gravure roller 2 to ensure the safety of the micro-gravure roller 2; in addition, when the yaw angle of the scraper 31 needs to be adjusted, one end of the scraper 31 mounting seat is moved by adjusting one of the first servo motors 41, so that only the yaw angle of the scraper 31 changes without affecting its position.

[0038] Further, the first linear transmission mechanism 42 includes a scraper moving seat 422 and an adjusting rod 421, the scraper moving seat 422 is slidably connected to the top of the rotating fixed seat 53 in the scraper rotating assembly 5, specifically, a linear slide 423 is provided at the top of the rotating fixed seat 53, and a slide groove is provided at the bottom of the scraper moving seat 422, and the slide groove is slidably connected to the linear slide rail 423.

[0039] Furthermore, a length mark is provided on the rotating fixed seat 53, and the length mark is arranged along the length direction of the linear slide rail 423. In this embodiment, the length mark adopts a ruler 424, and the ruler 424 is located below the linear slide rail 423. The ruler 424 can be used to intuitively observe the displacement distance of the scraper moving seat 422, that is, the displacement distance of the scraper 31 can be accurately known.

[0040] In a specific embodiment, referring to Figure 2 , Figure 5 and 7The scraper lifting assembly 6 includes a third servo motor 61 and a second linear transmission mechanism 62. The output shaft of the third servo motor 61 is used to drive the second linear transmission mechanism 62 to operate. When the second linear transmission mechanism 62 operates, it is used to drive the scraper rotating assembly 5 to rise and fall. The scraper displacement assembly 4 and the scraper assembly 3 are synchronously lifted and lowered with the scraper rotating assembly 5. Specifically, the second linear transmission mechanism 62 includes a transmission shaft 621, a screw module and a linear guide rail. The third servo motor 61 drives the screw 624 of the screw module to rotate through the transmission shaft 621. More specifically, the transmission shaft 621 is arranged parallel to the micro-gravure roller 2. Both ends of the transmission shaft 621 are connected with a screw module.

The changing gear box 623 is provided with a changing gear to change the torsional output direction of the transmission shaft 621 to the torque output direction of the screw 624. That is, through the action of the transmission shaft 621, the first reducer 622 and the changing gear box 623, the output shaft of the third servo motor 61 can drive the screw 624 to rotate.

[0041] The screw rod 624 in the screw rod module is installed on the wall panel 1 through the screw rod fixing seat 626, and the nut 625 in the screw rod module is installed on the wall panel 1 through the linear guide rail. Specifically, the slide rail 627 of the linear guide rail is fixed on the wall panel 1, and the slider 628 of the linear guide rail is fixedly connected to the nut 625, so as to guide and support the nut 625 to move in the vertical direction, and then when the output shaft of the third servo motor 61 drives the screw rod 624 to rotate, the nut 625 is driven to move up and down. In addition, a through hole 6251 is provided on the nut 625, and the rotating shaft 52 of the scraper rotating assembly 5 is rotatably connected in the through hole 6251, so that the scraper rotating assembly 5 rises and falls synchronously with the nut 625, thereby driving the scraper 31 to rise and fall.

The two scraper displacement assemblies 4 are respectively mounted on one of the rotating fixed seats 53. The second servo motor 51 is fixed to the nut 625 through a motor mounting bracket. The output shaft of the second servo motor 51 is connected to one end of the rotating shaft 52 through a second reducer 55. In this way, the rotating shaft 52 is driven to rotate by the second servo motor 51, so as to drive the rotating fixed seat 53 and the scraper displacement assembly 4 fixed on the rotating fixed seat 53 to rotate, and then drive the scraper fixed seat 32 connected to the scraper displacement assembly 4 to rotate, so as to achieve the adjustment of the angle of the scraper 31.

[0043] Furthermore, the end of the rotating shaft 52 passes through the second reducer 55 and a pointer 56 is provided at its end. An angle mark is provided on the outer shell of the second reducer 55. The angle mark is arranged circumferentially along the rotating shaft 52.
