Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, and more specifically to a dust removal structure for coating machines. Background Art

[0002] Coating machines are mainly used for surface coating production of films, paper, etc. This machine coats the rolled substrate with a layer of glue, paint or ink with specific functions, and then cuts it into sheets or reels it after drying.

[0003] However, in existing coating machines, when the transmission roller contacts and transmits objects such as films and papers, the friction contact on the transmission roller surface easily causes static electricity to be generated on the transmission roller surface, thereby causing dust to adhere. As a result, when the film and paper are subsequently conveyed, the dust passively adheres to the surface of the film and paper again, reducing the qualified rate of the product and making it inconvenient for users to use.

[0004] Therefore, it is necessary to redesign the coating machine to effectively prevent dust from adhering to the surface of films, paper, etc. Utility Model Content

[0038] [[ID=z7]]Please refer toFigures 1-6 , a dust removal structure for a coating machine, including a coating machine body 1. Between the inner walls on the middle side of the coating machine body 1, a composite roller 2, a pressure roller 3 and a plurality of small guide rollers 4 are installed. Between the inner walls on the right side of the coating machine body 1, two rolls of material 5 are installed in an up-and-down mirror distribution. On the left inner wall of the coating machine body 1, a bracket 6 is fixedly connected. Between the inner walls of the bracket 6, a dust suction member 7 is provided. At the left end of the coating machine body 1, a support seat 8 is fixedly connected. Between the inner walls of the support seat 8, a roll of material 9 is installed. On both inner walls of the support seat 8, adjusting brackets 10 are movably installed through bolts. Between the inner walls of the adjusting brackets 10, a small guide roller 11 is installed. On the rear inner wall of the support seat 8, an electrostatic elimination component is provided, and the electrostatic elimination component is located at the upper side of one side of the small guide roller 11.

[0039] During the use of this solution, in order to make it so that when the existing coating machine is in use, dust is not easily adhered to the surfaces of the film and paper, and to ensure the product quality during subsequent winding. In this embodiment, when the film and paper products are being transported, personnel can pre-adjust the tightness of the bolts to drive the adjusting bracket 10 and the small guide roller 11 to rotate to an appropriate angle, so as to adjust the tension of the film and paper during transportation. During transportation, the electrostatic elimination component conducts the static electricity generated by the friction between the small guide roller 11 and the film and paper during transportation, so as to prevent the phenomenon that static electricity is generated on the surface of the film and paper and dust is actively adhered. Subsequently, as the film and paper continue to be transported, the dust suction member 7 actively sucks the surface of the film and paper again in the early stage of the coating operation of the film and paper, so as to clean the dust passively adhered to the surface of the film and paper in the air, ensure the cleanliness of the surface of the film and paper, and facilitate subsequent coating operations and product quality.

[0040] Please refer to Figure 1 and Figures 5-6 , the electrostatic elimination component includes a plurality of through holes 121 opened at the outer end of the support seat 8. A positioning plate 122 is sleeved on the upper end of the support seat 8. A stud 123 is threadedly connected to the rear end of the positioning plate 122. One end of the stud 123 penetrates between the inner walls of the through holes 121. A connecting shaft 124 is fixedly connected to the front end of the positioning plate 122. A connecting seat 125 is sleeved on the outer end of the connecting shaft 124. A conductive bar 126 is sleeved on one end of the connecting seat 125. A conductive wire 127 is provided on the upper side of the conductive bar 126. One end of the conductive bar 126 is located on the upper surface of the small guide roller 11. The connecting seat 125, the conductive bar 126 and the conductive wire 127 are fixedly connected by bolts. The other end of the conductive wire 127 is fixedly connected to a grounding bar 128, and a grounding wire is installed at one end of the grounding bar 128.

[0041] During use of this solution, since the position of the small guide roller 11 can be adjusted arbitrarily according to the tension of the film or paper, before conducting the static electricity on the surface of the small guide roller 11, the personnel can move the positioning plate 122 to the appropriate through-hole 121 according to the position of the small guide roller 11, and then screw the stud 123 to cause the stud 123 to penetrate into the appropriate through-hole 121. Subsequently, the personnel rotate the connecting seat 125 and the associated conductive strip 126 to the upper surface of the small guide roller 11, and the conductive strip 126 is located at the side end of the small guide roller 11, which does not affect the conveying path of the film or paper. Then, when static electricity is generated by friction between the small guide roller 11 and the film or paper, the static electricity can be discharged through the grounding bar 128 and the connecting wire under the conductive action of the conductive wire 127, making it difficult for the film or paper to adhere to the static electricity effect. As a result, the film or paper can no longer actively adhere to dust during transportation, which greatly avoids the adhesion of dust to the film or paper.

[0042] See also Figures 1-4 The dust collecting member 7 includes a connecting plate 71 whose upper ends of the inner walls of the two brackets 6 are connected by bolts, and a ventilation duct 72 is fixedly connected between the inner walls of the connecting plate 71 by bolts. A plurality of evenly distributed air inlets 73 are opened at the left end of the ventilation duct 72, and two symmetrically distributed air pipes 74 are installed through the lower end of the ventilation duct 72. The lower end of the air pipe 74 is fixedly connected to a dust collecting box 75, and a suction fan 76 is installed at the left end of the dust collecting box 75.

[0043] More specifically, a cavity 721 is provided at the right end of the ventilation duct 72, and a plurality of contacting dust collecting parts 722 are fixedly connected to the left and right inner walls of the cavity 721. The dust collecting parts 722 include rubber strips and plastic strips, and a plurality of elastic plates 723 are fixedly connected to the inner wall of one side of the cavity 721.

[0044] More specifically, a dust box 751 is provided between the inner walls of the dust box 75, a dust collecting pad 752 is attached to the inner wall of the dust box 751, a filter 753 is installed on the left end of the dust box 751, and a built-in groove 754 is opened at the front end of the coating machine body 1.

[0045] During the use of this solution, before the film and paper are coated, under the action of the suction fan 76, the surface of the film and paper is actively sucked, and the dust adhered to the surface of the film and paper passively is sucked from the cavity 721. The air and the dust adhered to the surface of the film and paper pass through the dust collecting member 722. Due to the diversion of the air, the rubber strip and the plastic strip in the elastic plate 723 continuously collide and rub against each other, generating a large amount of static electricity coefficient between them. As a result, when the dust passes through the elastic plate 723, the dust is adhered and retained in the cavity 721 for collection, and the air then passes through the air pipe 74 and the dust collecting box 75, and finally is released from the air outlet side of the suction fan 76;

[0046] At the same time, in this embodiment, with the setting of the elastic plate 723, the elastic plate 723 can also continuously vibrate under the action of the air flow, so as to strike the dust attached to the surface of the elastic plate 723, making the dust adhered to the surface of the elastic plate 723 gradually fall off and be collected in the dust collecting box 751 along the air pipe 74. At the same time, it also ensures that the elastic plate 723 is not easily adhered with too much dust, resulting in the weakening of the dust suction effect;

[0047] Subsequently, the dust suction pad 752 can adhere to the dust to avoid the occurrence of wanton flying affected by the air flow. At the same time, with the setting of the filter screen 753, it can ensure that the dust is not easily dispersed outward by the suction fan 76, avoiding environmental pollution;

[0048] Finally, the operator can remove the bolt between the bracket 6 and the connecting plate 71, so as to remove the connecting plate 71 on one side. At this time, the operator can pull out the dust collecting box 751 and take it out from the inside of the dust collecting box 75, and then clean the dust inside uniformly.

[0049] The above embodiments only represent a certain implementation mode of the present invention, and its description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
