Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a coating device with an anti-deviation mechanism for printing. Background Art

[0002] Coating machines are mainly used in the surface coating process production of films, paper, etc. Coating machines coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then dry and rewind it. Rewinding is an important process on the coating machine, that is, the coated substrate is rewound using a rewinding device. The rewinding equipment on existing coating machines does not have an anti-deviation device for the substrate. Part of the reason for the substrate deviation is that the rewinding shaft and the pressure roller are far apart during the rewinding process. At this time, the substrate extends longer and has no support and limit mechanism. During the rewinding process, the film product moves left and right. Therefore, when the film product is rolled up in the free position during rewinding, the edges will be uneven. When the deviation is serious, the substrate cannot be rewound, affecting the normal and continuous operation of the coating machine. Therefore, to address the above problems, a coating device with an anti-deviation mechanism for printing is proposed. Utility Model Content

[0003] The purpose of the utility model is to provide a coating device with an anti-deviation mechanism for printing, so as to solve the problems raised in the above background technology.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] As an optional solution of the coating device with anti-deviation mechanism for printing described in the utility model, wherein: a coating device with anti-deviation mechanism for printing comprises a printing coating device, a drying device, a winding device and a printing substrate,

[0006] A drying device for drying the printed substrate is provided on one side of the printing and coating device, and a winding device for winding the printed substrate is provided on one side of the drying device;

[0007] A guide mechanism for guiding the printed substrate is installed on one side of the winding device, and an anti-deviation component fixedly connected to the drying device is also provided between the winding device and the drying device;

[0008] The anti-deviation assembly includes a connecting frame, a rotating platform and a limiting frame, one end of the connecting frame is fixedly connected to the drying device, the other end of the connecting frame is rotatably connected to the rotating platform, and the other end of the rotating platform is fixedly connected to the limiting frame, a printing substrate is arranged inside the limiting frame, and a cleaning mechanism is installed above the limiting frame;

[0009] An extension plate is fixedly connected to one side of the connecting frame, a vertically arranged threaded sleeve is rotatably connected to the interior of the extension plate, a threaded shaft is spirally connected to the interior of the threaded sleeve, and a slider is rotatably connected to the top of the threaded shaft, and the top of the slider is slidably connected to the limit frame;

[0010] The cleaning mechanism includes a mounting frame, a motor and fan blades. The outer side of the mounting frame is fixedly connected to the limit frame. The inner side of the mounting frame is fixedly connected to the motor. The end of the main shaft of the motor is fixedly connected to the fan blades.

[0011] An air outlet nozzle arranged in an inclined manner is also installed on one side of the installation frame.

[0012] Coating machines are mainly used for surface coating production of films, paper, etc. Coating machines coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then rewind it after drying. Winding is a critical process in a coating machine, where the coated substrate is wound up using a winding device. Existing winding devices on coating machines lack a device to prevent substrate deviation. Substrate deviation is partly due to the long distance between the winding shaft and the pressure roller during winding. The substrate is stretched out and lacks support and limiting mechanisms. During the winding process, the film product moves left and right, resulting in uneven edges when the film product is rolled up in the free position. In severe cases of deviation, the substrate cannot be wound up, affecting the normal and continuous operation of the coating machine. This device is externally connected and has an anti-swing component installed between the winding device and the drying device. The printed substrate is passed through a limit frame, which provides support and positioning to prevent the printed substrate from shaking during winding. Simultaneously, the threaded sleeve rotates, driving the threaded shaft and the slider, which in turn drives the limit frame to rotate around the turntable. The limit frame angle can be adjusted to match the inclination of the printed substrate, ensuring stable movement of the printed substrate and preventing edge deviation during winding.

[0013] As an optional solution of the coating device with anti-deviation mechanism for printing described in the utility model, the guide mechanism includes a guide frame and a guide roller, one side of the guide frame is fixedly connected to the winding device, and the other side of the guide frame is rotatably connected to the guide roller.

[0014] When the printing substrate is being rolled up, the guide roller can be used to press the printing substrate tightly to ensure that the printing substrate is taut and can be rolled up stably.

[0015] As an optional solution of the coating device with anti-deviation mechanism for printing described in the utility model, a ventilation channel is opened inside the installation frame, a spring is arranged inside the ventilation channel, one end of the spring is fixedly connected to the installation frame, and the other end of the spring is fixedly connected to a sliding plate, and the outer side of the sliding plate is slidably connected to the installation frame.

[0016] As an optional solution of the coating device with anti-deviation mechanism for printing described in the utility model, bumps are fixedly connected to both sides of the lower side of the sliding plate, and the outer sides of the bumps are slidably connected to the mounting frame.

[0017] The motor starts and drives the fan blades to rotate, which can drive the air to be discharged through the air outlet nozzle to clean the dust and impurities on the surface of the printing substrate. In order to prevent the air outlet nozzle from discharging air too quickly and affecting the movement of the printing substrate, a ventilation channel is provided at this time. When the air flows too fast, the air squeezes the sliding plate to move upward, causing the air to be discharged from above, reducing the exhaust volume of the air outlet nozzle and protecting the printing substrate.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] When the utility model is in use, an anti-deviation assembly is provided between the winding device and the drying device, and the printed substrate is passed through the limit frame, and the limit frame plays the purpose of supporting and limiting, thereby preventing the printed substrate from shaking during winding. At the same time, the threaded shaft is driven to move by rotating the threaded sleeve, thereby moving the slider, and the slider drives the limit frame to rotate with the rotating table as the center. At this time, the angle of the limit frame can be adjusted to adapt to the inclination angle of the printed substrate, thereby ensuring the stable movement of the printed substrate and preventing the edge of the printed substrate from deviating during winding.

[0020] When the motor starts, the fan blades rotate, which can drive the air to be discharged through the air outlet nozzle to clean the dust and impurities on the surface of the printing substrate. In order to prevent the air outlet nozzle from blowing out too fast and affecting the movement of the printing substrate, a ventilation channel is provided. When the air flows too fast, the air squeezes the sliding plate upward, causing the air to be discharged from above, reducing the exhaust volume of the air outlet nozzle and protecting the printing substrate.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1 and Figure 3 , the utility model provides a technical solution:

[0030] A coating device for printing with an anti-deviation mechanism comprises a printing coating device 1, a drying device 2, a winding device 3 and a printing substrate 4.

[0031] A drying device 2 for drying the printed substrate 4 is provided on one side of the printing and coating device 1, and a winding device 3 for winding the printed substrate 4 is provided on one side of the drying device 2;

[0032] A guide mechanism 5 for guiding the printing substrate 4 is installed on one side of the winding device 3, and an anti-deviation component 6 fixedly connected to the drying device 2 is also provided between the winding device 3 and the drying device 2;

[0033] The anti-deviation assembly 6 includes a connecting frame 601, a rotating platform 602, and a limiting frame 603. One end of the connecting frame 601 is fixedly connected to the drying device 2, and the other end of the connecting frame 601 is rotatably connected to the rotating platform 602. The other end of the rotating platform 602 is fixedly connected to the limiting frame 603. The printing substrate 4 is arranged inside the limiting frame 603, and a cleaning mechanism 608 is installed above the limiting frame 603.

[0034] An extension plate 604 is fixedly connected to one side of the connecting frame 601. A vertically arranged threaded sleeve 605 is rotatably connected to the interior of the extension plate 604. A threaded shaft 606 is spirally connected to the interior of the threaded sleeve 605. A slider 607 is rotatably connected to the top of the threaded shaft 606. The top of the slider 607 is slidably connected to the limit frame 603.

[0035] The cleaning mechanism 608 includes a mounting frame 6081, a motor 6082, and fan blades 6083. The outer side of the mounting frame 6081 is fixedly connected to the limit frame 603. The interior of the mounting frame 6081 is fixedly connected to the motor 6082. The end of the main shaft of the motor 6082 is fixedly connected to the fan blades 6083.

[0036] An air outlet nozzle 6084 arranged at an angle is also installed on one side of the above-mentioned installation frame 6081.

[0037] Coating machines are mainly used for the surface coating process production of films, paper, etc. Coating machines coat the rolled substrate with a layer of glue, paint or ink, etc. with specific functions, and then rewind it after drying. Rewinding is an important process on the coating machine, that is, the coated substrate is rewound by a rewinding device. The rewinding device on the existing coating machine does not have an anti-deviation device for the substrate. Part of the reason for the substrate deviation is that the distance between the rewinding shaft and the pressure roller is far during the rewinding process. At this time, the substrate extends longer and has no support and limiting mechanism. During the rewinding process, the film product moves left and right. Therefore, when the film product is rolled up in a free position during rewinding, the edges will be uneven. When the deviation is serious, the substrate cannot be rewound, affecting the normal and continuous operation of the coating machine. When this device is used, it is externally connected to the rewinding device 3 and the drying device. An anti-deviation assembly 6 is provided between the dry equipment 2. The printing substrate 4 is passed through the limit frame 603. The limit frame 603 serves the purpose of supporting and limiting, preventing the printing substrate 4 from shaking during winding. At the same time, by rotating the threaded sleeve 605, the threaded sleeve 605 drives the threaded shaft 606 to move, and the slider 607 moves. The slider 607 drives the limit frame 603 to rotate around the rotating table 602. At this time, the angle of the limit frame 603 can be adjusted to adapt to the inclination angle of the printing substrate 4, ensuring the stable movement of the printing substrate 4 and preventing the edge of the printing substrate 4 from deviating during winding.

[0038] In this embodiment, the motor 6082 is started to drive the fan blades 6083 to rotate, which can drive the air to be discharged through the air outlet nozzle 6084. The air outlet nozzle 6084 is arranged at an inclined longitudinal position. At this time, it can ensure that the discharged air can fully clean the dust and impurities on the surface of the printing substrate 4, thereby ensuring the quality of the printing substrate 4.

[0039] Example 2

[0040] This embodiment is an improvement on embodiment 1. Figure 2Specifically, the guide mechanism 5 includes a guide frame 501 and a guide roller 502. One side of the guide frame 501 is fixedly connected to the winding device 3, and the other side of the guide frame 501 is rotatably connected to the guide roller 502.

[0041] When the printing substrate 4 is being rolled up, a guide roller 502 is installed at one end of the guide frame 501 . The guide roller 502 can be used to press the printing substrate 4 to ensure that the printing substrate 4 is taut and that the printing substrate 4 is rolled up stably.

[0042] Example 3

[0043] This embodiment is an improvement on embodiment 2. Figure 4 and Figure 5 Specifically, a ventilation channel 6085 is opened inside the above-mentioned installation frame 6081, and a spring 6087 is provided inside the above-mentioned ventilation channel 6085. One end of the above-mentioned spring 6087 is fixedly connected to the installation frame 6081, and the other end of the above-mentioned spring 6087 is fixedly connected to the sliding plate 6086. The outer side of the above-mentioned sliding plate 6086 is slidably connected to the installation frame 6081.

[0044] Bumps are fixedly connected to both sides of the bottom of the sliding plate 6086 , and the outer sides of the bumps are slidably connected to the mounting frame 6081 .

[0045] When cleaning the dust on the upper surface of the printing substrate 4, in order to prevent the air outlet nozzle 6084 from blowing out air too quickly and affecting the movement of the printing substrate 4, a ventilation channel 6085 is provided. When the air flows too fast, the air squeezes the sliding plate 6086 to move upward, the spring 6087 is stretched, and the sliding plate 6086 is separated from the mounting frame 6081. At this time, the air is discharged from the top, reducing the exhaust volume of the air outlet nozzle 6084, thereby protecting the printing substrate 4. The protrusion under the sliding plate 6086 is used to ensure that the sliding plate 6086 is stably located inside the ventilation channel 6085 when it is reset, thereby ensuring the subsequent use of the device.
