Technical Field

[0001] The utility model relates to the technical field of coating and printing, in particular to a coating and rapid printing device. Background Art

[0002] Tinplate is the basic material for the preparation of tin cans, and the surface of tinplate needs to be coated during processing. A layer of specific functional coating is coated on the rolled tinplate substrate through a coating machine.

[0003] A coating fast printing device disclosed in Chinese patent CN220444221U is an improvement on a coating production printing device disclosed in CN218945509U, solving the inconvenience problem in Chinese patent CN218945509U;

[0004] The coating production printing equipment disclosed in Chinese patent CN218945509U is an improvement on the uniform coating printing coating machine disclosed in Chinese patent CN213612305U, solving the problem that the materials such as glue, coating or ink in CN213612305U are constantly accumulated and cannot be processed or recycled;

[0005] The two coating printing devices of the above-mentioned Chinese patent CN220444221U and Chinese patent CN218945509U solve the problem of continuous accumulation of materials such as glue, coating or ink in Chinese patent CN213612305U and inability to process or recycle them, but have the following defects:

[0006] After the two coating and printing devices of Chinese patent CN220444221U and Chinese patent CN218945509U clean up the excess glue, coating or ink and other materials in time, if the thickness of the material coated on the surface of the subsequent base material is not enough, secondary smoothing cannot be performed, resulting in the problem of lack of secondary smoothing effect, thus affecting the problem of coating uniformity. Utility Model Content

[0007] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0008] To this end, one purpose of the utility model is to provide a coating rapid printing device, aiming to solve the problem that the coating printing device in the prior art has the ability to recycle materials such as glue, coating or ink, but does not have a secondary smoothing effect.

[0009] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one hand provides a coating rapid printing device, including a printing device body and a scraper, characterized in that the scraper is fixedly installed inside the printing device body, a collecting trough is opened on one side of the top of the scraper, and baffles are fixedly connected at both ends of the scraper, one of the baffles is opened with a discharge hole, and a return pipe is fixedly connected to the outer side of the baffle corresponding to the discharge hole.

[0010] Preferably, any of the above schemes has a chamfer on the front side of the scraper. When the base material is conveyed quickly, the chamfer allows the glue scraped off by the scraper to flow obliquely upward into the collecting trough by inertia, thereby avoiding the problem of excessive glue accumulating in front of the scraper.

[0011] Preferably, any of the above schemes has a rubber roller, a glue coating roller, a transmission roller and a brush roller rotatably connected inside the printing device body, and a mounting groove is provided on the front side of the printing device body to facilitate the installation of the base material.

[0012] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0013] 1. Excess glue on the top of the base material will accumulate between the scraper and the two baffles. When the glue accumulates to a certain thickness, it will enter the aggregate trough from above the scraper and then be recovered through the reflux pipe. When the part of the base material surface with less glue passes through the scraper, the glue accumulated in front of the scraper will be used to smooth the base material for the second time, which has the advantages of recycling and secondary smoothing.

[0014] 2. The installation groove exposes the rubber roller, the glue coating roller, the transmission roller and the brush roller, so that when installing the base material, it is convenient to insert the base material between the rubber roller, the glue coating roller, the transmission roller and the brush roller.

[0015] 3. By opening a chamfer on the front side of the scraper, the excess glue scraped off by the scraper will move upward along the chamfer of the scraper due to inertia, and thus smoothly enter the inside of the aggregate trough, avoiding the problem that the excess glue hits the scraper when the base material is conveyed quickly, and the reaction force causes the glue to move to the front side of the scraper, out of the blocking range of the baffle, and causes it to spill from both sides of the base material.

[0026] The utility model provides a coating fast printing device.

[0027] Embodiment 1:

[0028] like Figure 1-5As shown, it includes a printing device body 1 and a scraper 2, characterized in that the scraper 2 is fixedly installed inside the printing device body 1, a collecting trough 21 is opened on one side of the top of the scraper 2, which is used to collect excess glue in front of the scraper 2, and baffles 22 are fixedly connected at both ends of the scraper 2. The baffles 22 are used to block the glue in the collecting trough 21 and in front of the scraper 2 to prevent the glue from spilling to both sides, and positioning blocks 25 are fixedly connected to the outer sides of the two baffles 22. The baffles 22 are fixedly installed inside the printing device body 1 through the positioning blocks 25, and a discharge hole 23 is opened on one of the baffles 22. A return pipe 24 is fixedly connected to the outer side of the baffle 22 at a position corresponding to the discharge hole 23. The glue in the collecting trough 21 can be discharged through the discharge hole 23 and then recovered through the return pipe 24.

[0029] Specifically, Figure 2-3 As shown, the inside of the printing device body 1 is rotatably connected with a rubber roller 3, a glue coating roller 4, a transmission roller 5 and a brush roller 6, and both ends of the rubber roller 3, the transmission roller 5 and the brush roller 6 are fixedly connected with positioning shafts. The rubber roller 3, the transmission roller 5 and the brush roller 6 are rotatably connected to the inside of the printing device body 1 through the positioning shaft, and one end of the glue coating roller 4 is fixedly connected to a feed pipe 41, and the other end is fixedly connected to the positioning shaft. The glue coating roller 4 is rotatably connected to the printing device body 1 through the positioning shaft and the feed pipe 41, and a rotating joint 84 is fixedly installed on one end of the feed pipe 41.

[0030] Specifically, Figure 2 As shown, a material storage box 8 is provided inside the printing device body 1, and a discharge pipe 81 is fixedly connected to one side of the bottom of the material storage box 8, a hydraulic pump 82 is fixedly installed at one end of the discharge pipe 81, and a delivery pipe 83 is fixedly installed at the output end of the hydraulic pump 82, and the delivery pipe 83 is fixedly installed with a rotary joint 84 at one end away from the hydraulic pump 82. The hydraulic pump 82 extracts glue from the material storage box 8 through the discharge pipe 81, and then delivers it to the feed pipe 41 through the delivery pipe 83, and then delivers it to the inside of the glue coating roller 4 through the feed pipe 41. The function of the rotary joint 84 is that during the rotation of the feed pipe 41, the delivery pipe 83 will not rotate, thereby ensuring that the glue coating roller 4 can rotate smoothly.

[0031] Specifically, Figure 2 As shown, one end of the return pipe 24 is fixedly connected to a material guide pipe 26, and the end of the material guide pipe 26 away from the return pipe 24 is connected to the storage box 8. The return pipe 24 is connected above the storage box 8, and the glue discharged from the collecting trough 21 through the return pipe 24 enters the interior of the storage box 8 through the material guide pipe 26.

[0032] Preferably, Figure 1As shown, a mounting groove 11 is opened on the front side of the printing device body 1, exposing the rubber roller 3, the glue coating roller 4, the transmission roller 5 and the brush roller 6, so that when the base material 7 is installed, it is convenient to insert the base material 7 between the rubber roller 3, the glue coating roller 4, the transmission roller 5 and the brush roller 6.

[0033] Embodiment 2:

[0034] like Figure 3-5 As shown, on the basis of Example 1, a chamfer is provided on the front side of the scraper 2. When the base material 7 is conveyed quickly, after a certain thickness of glue accumulates on the front side of the scraper 2, the excess glue scraped off by the scraper 2 will move obliquely upward along the chamfer of the scraper 2 due to inertia, thereby smoothly entering the interior of the collecting trough 21, thereby avoiding the problem that when the base material 7 is conveyed quickly, the excess glue collides with the scraper 2, and the reaction force causes the glue to move to the front side of the scraper 2, out of the blocking range of the baffle 2, and causes it to spill from both sides of the base material 7.

[0035] The working principle of the utility model is as follows: when in use, the base material 7 is passed between the rubber roller 3 and the glue coating roller 4, then goes around from the bottom of the transmission roller 5 to the top of the brush roller 6, and passes from the bottom of the scraper 2. When the base material 7 is transmitted, the excess glue on the top of the base material 7 will be blocked by the scraper 2 and accumulated between the scraper 2 and the two baffles 22. When the glue accumulates to a certain thickness, it will enter the collecting trough 21 along the chamfer of the scraper 2, and then enter the storage box 8 through the reflux pipe 24 and the guide pipe 26 for recovery. When the part of the surface of the base material 7 with less glue passes through the scraper 2, the glue accumulated in the front of the scraper 2 will smooth the base material 7 for a second time.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. Excess glue on the top of the base material 7 will be blocked by the scraper 2 and accumulated between the scraper 2 and the two baffles 22. When the glue accumulates to a certain thickness, it will enter the collecting trough 21 from above the scraper 2, and then enter the storage box 8 through the reflux pipe 24 and the guide pipe 26 for recycling. When the part of the surface of the base material 7 with less glue passes through the scraper 2, the glue accumulated in the front of the scraper 2 will perform secondary smoothing on the base material 7, which has the advantages of recycling and secondary smoothing.

[0038] 2. By opening a mounting groove 11 on the front side of the printing device body 1, the rubber roller 3, the glue coating roller 4, the transmission roller 5 and the brush roller 6 are exposed, so that when the base material 7 is installed, it is convenient to insert the base material 7 between the rubber roller 3, the glue coating roller 4, the transmission roller 5 and the brush roller 6.

[0039] 3. By providing a chamfer on the front side of the scraper 2, when the base material 7 is conveyed quickly, after a certain thickness of glue accumulates on the front side of the scraper 2, the excess glue scraped off by the scraper 2 will move obliquely upward along the chamfer of the scraper 2 due to inertia, thereby smoothly entering the interior of the collecting trough 21, thereby avoiding the problem that when the base material 7 is conveyed quickly, the excess glue collides with the scraper 2, and the reaction force causes the glue to move to the front side of the scraper 2, out of the blocking range of the baffle 2, and causes it to spill from both sides of the base material 7.
