Description

Technical Field

[0001] The utility model relates to the technical field of thermal paper coating, in particular to thermal paper surface coating equipment with good dustproof effect. Background Art

[0002] Thermal paper is a kind of processed paper. The manufacturing principle is to coat a layer of thermal coating (also called thermal coating) on ​​the outer surface of the base paper. When producing thermal paper labels such as name tags and clothing labels, a whole sheet of base paper is usually cut on a cutting machine, and then the base paper is transferred to the coating station. The coating roller is dipped in thermal coating and coated on the surface of the base paper. When both sides of the base paper need to be coated with thermal coating, after the thermal coating on one side of the base paper is dry, the uncoated side of the base paper will be turned over and coated with thermal coating again;

[0003] During the thermal paper coating process, dust and paper scraps generated by paper cutting will adhere to the base paper. If the dust and paper scraps on the base paper surface are not cleaned in time, it is easy to cause the dust and paper scraps to be coated on the base paper surface along with the thermal coating, affecting the production quality of thermal paper. At present, the dust-proof facilities used to clean dust and paper scraps on most thermal paper coating equipment have simple structures and single functions. The simple structure is reflected in that directly using a vacuum cleaner to suck the dust on the paper surface cannot fully clean the dust on both sides of the base paper, and the single function is reflected in that the limit fixation in the base paper coating process cannot be combined with the paper surface cleaning. Utility Model Content

[0004] The utility model aims to provide a thermal paper surface coating device with good dustproof effect to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The top of the tube is fixed with a support tube, and a dust hopper is connected to the top of the support tube, and a dust collector for sucking air into the dust hopper is fixed inside the tube. L-shaped frames are fixed on both sides of the support seat, and a cylinder is fixed on the outside of the L-shaped frame, and a crossbeam is fixed on the output ends of the two cylinders. The inside of the crossbeam is rotatably connected with a screw rod 2, and the outside of the screw rod 2 is screwed and connected with a paint box, and the bottom of the paint box is rotatably connected with a coating roller, and the bottom surface of the paint box is connected and fixed with a plurality of feeding pipes for conveying thermal sensitive paint to the coating roller at equal intervals.

[0007] Furthermore, one end of the support base is fixed with a first motor for driving the first lead screw to rotate, and one end of the cross beam is fixed with a third motor for driving the second lead screw to rotate.

[0008] Furthermore, a transmission block screwed to the second lead screw is fixed to the bottom of the paint tank, a feeding pipe is fixedly connected and communicated at one end of the paint tank, and L-shaped retaining strips are fixed to the bottoms of both ends of the cross beam.

[0009] Furthermore, a connecting shaft is inserted and fixed to the bottom of the connecting arm, gears meshing with each other are fixed to the outer sides of the two connecting shafts, and a rectangular notch for accommodating the gears is formed in the bottom of the connecting arm.

[0010] Furthermore, both ends of the connecting shaft are rotatably connected to the second U-shaped plate, and a second motor for driving the connecting shaft at the corresponding position to rotate is fixed to the outside of the second U-shaped plate.

[0011] Furthermore, a net plate is embedded and fixed to the top surface of the dust suction hopper, a connecting pipe is screwed to the bottom of the support pipe, and a filter screen is detachably fixed inside the connecting pipe.

[0012] Furthermore, a T-shaped pipe is fixedly connected and communicated with the suction end of the vacuum cleaner, hoses are fixedly connected and communicated with both ends of the T-shaped pipe, and one end of the hose背离 the T-shaped pipe is fixedly connected and communicated with the suction end of the vacuum cleaner.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. By laying the cut original paper on the surface of the net plate of a dust suction hopper, the vacuum cleaner sucks air through the hose into the dust suction hopper, making the bottom surface of the original paper in a negative pressure state, which facilitates sucking off the dust and paper scraps on the side of the original paper in contact with the net plate. At the same time, the original paper is adsorbed and fixed on the surface of the dust suction hopper. The two connecting arms rotate towards each other to combine the two dust suction hoppers. Similarly, the vacuum cleaner sucks air through the hose into the other dust suction hopper, so that the top surface of the original paper is also sucked and cleaned and can be adsorbed and fixed on the surface of the other dust suction hopper, which is convenient for comprehensively cleaning the outer surface of the original paper.

[0015] 2. The dust suction hopper adsorbs and fixes the cleaned original paper and transports the original paper to the lower part of the coating roller. The output end of the air cylinder drives the cross beam to move downward, so that the paint tank drives the coating roller to abut against the surface of the original paper. The external thermal-sensitive paint is pumped into the paint tank through the feeding pipe, and then is released from the feeding pipe to the outside of the coating roller. The coating roller rolls on the surface of the original paper to coat the thermal-sensitive paint on the original paper, realizing the manufacture of thermal paper. The dust suction hopper can not only suck the dust and paper scraps on the surface of the original paper, but also adsorb and fix the original paper to facilitate the coating roller to coat the thermal-sensitive paint. Therefore, the function of the dust suction hopper as a dust-proof function is diversified, and it is also beneficial to improve the coating efficiency of thermal paper.

[0016] 3. When a base paper for a dust suction hopper is supported for a coating roller to coat a thermal-sensitive coating, another base paper can be simultaneously placed on the surface of the other dust suction hopper, so that while one base paper is being coated with the thermal-sensitive coating, the other base paper is simultaneously sucked and cleaned of dust and paper scraps by the dust suction hopper, thereby enabling the cleaning of the base paper and the coating of the thermal-sensitive coating to be carried out synchronously, which is conducive to improving the overall efficiency of the cleaning and coating of the thermal-sensitive paper.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figure 1-4, in the embodiment of the present utility model, a coating device for the surface of thermal paper with good dust-proof effect includes a support base 100. A first lead screw 110 is rotatably connected inside the support base 100. A first U-shaped plate 200 is screwed and connected to the outside of the first lead screw 110. A second U-shaped plate 210 is fixed to the top of the first U-shaped plate 200. Two connecting arms 300 that are meshed and driven with each other are rotatably connected inside the second U-shaped plate 210. A support tube 400 is fixed to the top of the connecting arm 300. A dust suction hopper 410 is connected and fixed to the top of the support tube 400 in a communicating manner. A vacuum cleaner 220 for sucking air into the dust suction hopper 410 is fixed inside the first U-shaped plate 200. L-shaped frames 120 are fixed to both sides of the support base 100. A cylinder 121 is fixed to the outside of the L-shaped frame 120. Cross beams 500 are fixed to the output ends of the two cylinders 121. A second lead screw 510 is rotatably connected inside the cross beam 500. A coating tank 600 is screwed and connected to the outside of the second lead screw 510. A coating roller 610 is rotatably connected to the bottom of the coating tank 600. A plurality of blanking pipes 620 for conveying thermal coating to the coating roller 610 are connected and fixed to the bottom surface of the coating tank 600 at equal intervals.

[0026] Specifically, by providing two dust suction hoppers 410, a piece of base paper is placed on one of the dust suction hoppers 410. The bottom surface of the base paper is sucked by the dust suction hopper 410 to pre-clean the bottom surface of the base paper. Then, the two dust suction hoppers 410 are combined so that the top surface of the base paper contacts the other dust suction hopper 410, and the other dust suction hopper 410 sucks the dust and paper scraps on the top surface of the base paper alone, realizing a full-range cleaning of the surface of the base paper. The dust suction hopper 410 can also adsorb and fix the base paper and convey it to the lower part of the coating roller 610, facilitating the coating roller 610 to coat the thermal coating on the surface of the base paper. The dust suction hopper 410 can not only suck the dust and paper scraps on the surface of the base paper, but also adsorb and fix the base paper to facilitate the coating roller 610 to coat the thermal coating, thus diversifying the functions of the dust suction hopper 410 as a dust-proof function and being beneficial to improving the coating efficiency of thermal paper.

[0027] As Figure 4 shown, in this embodiment, a first motor 130 for driving the first lead screw 110 to rotate is fixed to one end of the support base 100, and a third motor 530 for driving the second lead screw 510 to rotate is fixed to one end of the cross beam 500.

[0028] In this embodiment, the first motor 130 drives the first lead screw 110 to rotate, so that the first U-shaped plate 200 screwed and connected to it drives the two dust suction hoppers 410 to move towards the coating roller 610, and then the dust suction hopper 410 conveys the base paper to the lower part of the coating roller 610 for coating standby. The third motor 530 drives the second lead screw 510 to rotate, so that the coating tank 600 screwed and connected to the second lead screw 510 can drive the coating roller 610 to roll back and forth on the surface of the base paper, facilitating the coating of the thermal coating on the surface of the base paper.

[0029] As Figure 3 As shown, in this embodiment, a transmission block 630 screwed to the second lead screw 510 is fixed to the bottom of the paint tank 600. One end of the paint tank 600 is connected and fixed with a feed pipe 640. L-shaped stoppers 520 are fixed to the bottoms of both ends of the cross beam 500.

[0030] In this embodiment, when the second lead screw 510 rotates, the transmission block 630 slides along the cross beam 500, and then the paint tank 600 moves along the cross beam 500. The feed pipe 640 facilitates the pumping of external paint into the paint tank 600. As the cross beam 500 moves downward, the L-shaped stoppers 520 can press against the edge of the base paper to further limit and fix the position of the base paper.

[0031] As Figure 1 and Figure 4 shown, in this embodiment, a connecting shaft 310 is inserted and fixed to the bottom of the connecting arm 300. Gears 311 that mesh with each other are fixed to the outer sides of the two connecting shafts 310. A rectangular notch for accommodating the gears 311 is formed at the bottom of the connecting arm 300. Both ends of the connecting shaft 310 are rotatably connected to the second U-shaped plate 210. A second motor 211 for driving the corresponding connecting shaft 310 to rotate is fixed to the outside of the second U-shaped plate 210.

[0032] In this embodiment, when the second motor 211 drives one of the connecting shafts 310 to rotate, the two connecting shafts 310 rotate synchronously through the meshing of the gears 311, and then the two connecting arms 300 can drive the two suction cups 410 to approach and clamp the base paper, facilitating the switching of the placement of the base paper on the surfaces of different suction cups 410, so that the bottom or top surface of the base paper can be arranged below the coating roller 610 for coating standby.

[0033] As Figure 2 shown, in this embodiment, a T-shaped pipe 221 is connected and fixed to the suction end of the vacuum cleaner 220. Hoses are connected and fixed to both ends of the T-shaped pipe 221. The end of the hose facing away from the T-shaped pipe 221 is connected and fixed to the suction end of the vacuum cleaner 220.

[0034] In this embodiment, solenoid valves are serially installed at both ends of the T-shaped pipe 221. The solenoid valves at different positions can be opened successively, enabling the two suction cups 410 to suck the base paper successively, facilitating the transfer of the base paper from one suction cup 410 to another, and facilitating the switching of different sides of the exposed base paper for coating the thermosensitive coating. Among them, the length of the hose meets the spatial requirements for the flipping of the two suction cups 410.

[0035] During specific implementation, the initial state refers to the instruction manual Figure 2, a piece of cut paper is placed on the top of a dust hopper 410, and the vacuum cleaner 220 sucks the air on the surface of the dust hopper 410 at this position through a hose, so that the dust and paper scraps on the bottom of the paper can be sucked and cleaned through the mesh plate 411, and then the motor 211 drives the two connecting arms 300 to bring the two dust hoppers 410 closer to each other and merge (refer to the manual Figure 4 ), after merging, another dust hopper 410 adsorbs and fixes the base paper, the dust hopper 410 that initially adsorbs and fixes the base paper stops adsorbing the base paper, and then the motor two 211 drives the two connecting arms 300 with the two dust hoppers 410 to unfold into the initial state. At this time, the bottom and top surfaces of the base paper have been sucked clean, and the motor one 130 drives the dust hopper 410 to move with the base paper to the bottom of the coating roller 610, and the cylinder 121 moves the crossbeam 500 downward, so that the L-shaped baffle 520 and the coating roller 610 are both against the surface of the base paper, and the thermosensitive paint is pumped to the coating box 600 through the feed pipe 640. The thermosensitive paint is released from the feed pipe 620 to the surface of the coating roller 610, and the motor three 530 drives the coating roller 610 to roll on the surface of the base paper, so as to facilitate the coating of the thermosensitive paint on the surface of the base paper.

[0036] Embodiment 2

[0037] On the basis of the first embodiment, in order to clean out the paper scraps sucked out from the inside of the support tube 400, it is prevented that the paper scraps clog the hose and affect the effect of sucking out the dust.

[0038] like Figure 5 As shown, in this embodiment, a mesh plate 411 is embedded and fixed on the top surface of the dust hopper 410, a connecting pipe 420 is screwed and connected to the bottom of the support pipe 400, and a filter screen 421 is detachably fixed inside the connecting pipe 420.

[0039] Specifically, the vacuum cleaner 220 sucks the air inside the connecting pipe 420 through a hose, and the connecting pipe 420 then sucks the air inside the dust hopper 410 through the supporting pipe 400. The paper scraps entering the connecting pipe 420 can be intercepted by the filter 421 on the surface of the filter 421, and can be removed from the inside of the supporting pipe 400 by loosening the connecting pipe 420, making it convenient to remove the paper scraps on the filter 421.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0041] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
