According to the uniform air suction type folding machine, the problem of a wide folding machine that the air suction force of certain air suction ports is not uniform when folding rollers rotate at a high speed is solved, the quality of folded paper is improved, the quality of broken paper is improved, halt caused by paper twining is avoided, production smoothness is guaranteed, high-power vacuum extraction equipment is not needed for the wide folding machine, and energy consumption of the machine is greatly reduced.
Description
Technical field
The utility model relates to the folder of producing folding napkin.
Background technology
Folder is for the production of the folding napkin such as face tissue, tissue.Folder all has two parallel folding rollers, and when paper is during through roll gap between two folding rollers, the folded roller of paper is rolled into "the" shape, realizes the folding of paper.The surface of folding roller is provided with the many groups inlet scoop distributing alternately along the circumferencial direction of folding roller, respectively organize inlet scoop respectively with roll body in an axial flow channel connection, this axial flow passage is through to the end face of roll body.
When folder work, along with the rotation of folding roller, in the time that a certain group of inlet scoop turns to ad-hoc location, the wind lid that is arranged on folding roller end will vacuumize from the end of the axial flow passage that is communicated with this group inlet scoop, makes this group inlet scoop draw rapidly paper to the roll surface of folding roller.In said process, because wind lid is to start to vacuumize from the end of axial flow passage, therefore cause following defect: 1, the fabric width of machine, the length that is folding roller can not exceed two meters conventionally, otherwise there will be air draught dynamics inhomogeneous in the time of folding roller High Rotation Speed, away from the air draught dynamics of the inlet scoop of folding roller end a little less than, be difficult to adsorb paper, simultaneously because air draught distance is longer, cause the generation of air draught time difference, the priority difference that the different parts of paper on folding roller length direction is adsorbed is obvious, these all can affect the quality of folded sheet, and the disconnected paper quality that the paper folding is cut off, even cause paper wrapping, make to produce and be forced to stop, 2, for the folder of wide cut, because air draught distance is longer, in the time of folding roller high speed rotating, realize the rapid vacuumizing of long distance, need to be equipped with very high-power vaccum-pumping equipment, therefore significantly improve machine power consumption values.
Utility model content
The purpose of this utility model is to provide the uniform folder of a kind of air draught, to address the above problem.
For this reason, the uniform folder of air draught described in the utility model, comprise two close to each other and parallel folding rollers, the surface of folding roller is provided with the many groups inlet scoop distributing alternately along the circumferencial direction of folding roller, every group of inlet scoop is made up of the inlet scoop of multiple arrangements of the length directions along folding roller, every group of inlet scoop at least with roll body in an axial flow channel connection, inlet scoop on the same group and different axial flow channel connection, do not draw the aspiration channel being connected with extraction equipment from the stage casing of each axial flow passage.
As optional embodiment, the utility model also can be taked following attached technical scheme.
Axial flow channel connection described in described every group of inlet scoop and two, these two axial flow passages cut off each other, draw respectively the aspiration channel described in from the stage casing of these two axial flow passages.
Axial flow channel connection described in described every group of inlet scoop and one, draws the aspiration channel described in two from the diverse location in the stage casing of this axial flow passage.
The utility model utilizes the stage casing extracting vacuum of aspiration channel from axial flow passage, bring thus following advantage: the air draught distance that 1, has shortened inlet scoop, avoid the air draught dynamics of wide cut folder some inlet scoop in the time of folding roller High Rotation Speed inhomogeneous, the different parts of paper on folding roller length direction almost adsorbed simultaneously, improve the quality of folded sheet, and the disconnected paper quality that the paper folding is cut off, avoid shutting down because of paper wrapping, guarantee the fluency of producing; 2, for the folder of wide cut, because air draught distance is shorter, do not need to be equipped with high-power vaccum-pumping equipment, can meet the requirement to inlet scoop rapid vacuumizing in the time of folding roller high speed rotating yet, significantly reduced machine power consumption values.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.Because the structure of two folding rollers in folder is identical, therefore the accompanying drawing of following each embodiment all only draws the semisectional view of a folding roller.On the other hand, the practical structures of folding roller includes the member such as platen cutter, platen groove, but these members and goal of the invention of the present utility model are irrelevant, and therefore the accompanying drawing of following each embodiment has all been done omission to these members.
Embodiment mono-
The folding roller of folder as shown in Figure 1, is provided with multiple inlet scoop 1a on the surface of folding roller.Inlet scoop 1a is divided into many groups, and every group of inlet scoop is made up of the inlet scoop 1a of multiple arrangements of the length directions along folding roller.Label " 1 " in Fig. 1 represents one group of inlet scoop wherein, and the inlet scoop of other groups is identical with it.Many groups inlet scoop 1 distributes alternately along the circumferencial direction of folding roller.Every group of inlet scoop 1 is communicated with two the axial flow passages 2,3 in roll body, and these two axial flow passages 2,3 cut off each other.Draw respectively an aspiration channel 4,5 from the stage casing of these two axial flow passages 2,3, these two aspiration channels 4,5 connect respectively two end faces to folding roller, and are connected with extraction equipment by wind lid 10.Wind lid 10 is fixed in frame, and its air suctiton inlet is close to the end face of folding roller.Extraction equipment (for example vacuum pump) is bled to aspiration channel 4,5 by wind lid 10.
