Description

Technical Field

[0001] The utility model belongs to the technical field of sizing machine feeding, and particularly relates to a feeding device for a curtain type sizing machine. Background Technique

[0002] During sizing in the soaking sizing mode, the prepared sizing liquid is transported into the feeding tank, and then sent between two sizing rollers of the sizing machine through an infusion pump. When the two sizing rollers drive the paper web to pass through the sizing liquid between the two sizing rollers, the paper web absorbs the sizing liquid at the same time to achieve the purpose of sizing, and the excess sizing liquid flows back to the feeding tank for cyclic sizing. The nozzles of the spray pipes arranged above the sizing rollers in the prior art are non-adjustable. Once set, they are fixed. When facing papers of different specifications, using a unified spraying method to produce papers of different specifications is likely to cause unqualified papers. Therefore, a spraying device capable of adjusting the flow rate of the nozzles is needed. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a feeding device for a curtain type sizing machine, which solves the problems in the above background technique.

[0004] The purpose of the utility model is achieved as follows: A feeding device for a curtain type sizing machine, which includes a feeding tank. The feeding tank is connected with a sizing pump through a pipeline. The sizing pump is in pipeline communication with a pressure screen. The pressure screen is in pipeline communication with an auxiliary sizing tank. A sizing roller is arranged at the lower working position of the auxiliary sizing tank. A cloth spreading pipe and a spray pipe are arranged above the sizing roller. The spray pipe includes a pipe body. The interior of the pipe body is divided into an upper layer space and a lower layer space by arranging a partition plate. A plurality of first spray nozzles communicated with the upper layer space are arranged on the upper side wall of the pipe body. A plurality of second spray nozzles communicated with the lower layer space are arranged on the lower side wall of the pipe body. A plugging device is arranged at the rear end of the pipe body. The tail end of the plugging device is connected with a driving device for driving the pipe body to rotate. The front end of the pipe body is communicated with a water supply device. An adjusting component is arranged inside the pipe body. During use, by spraying the sizing roller with different spray nozzles, the effect of adjusting the flow rate of the nozzles is achieved. When the first spray nozzles spray towards the sizing roller, the spraying flow rate is a large flow rate with fine water streams. When the second spray nozzles spray towards the sizing roller, the spraying flow rate is a small flow rate with thick water streams. Through the arrangement of the adjusting component, it is possible to quickly and flexibly adjust whether the first spray nozzles or the second spray nozzles discharge water, which is convenient and fast. Through the arrangement of the driving device, when the first spray nozzles discharge water, the driving device drives the pipe body to rotate to make the first spray nozzles face the sizing roller. When the second spray nozzles discharge water, the second spray nozzles face the sizing roller. The adjustment of the spray nozzles is mechanically realized, which is labor-saving and easy, and the positioning accuracy after adjustment is high.

[0005] Further, the adjusting component includes an upper guide hole formed in the upper side wall of the front end of the pipe body, and a lower guide hole formed in the lower side wall of the front end of the pipe body. An upper baffle is slidably connected inside the upper guide hole, and a lower baffle is slidably connected inside the lower guide hole. When in use, when the upper baffle is completely inserted into the upper guide hole and the lower baffle is not completely inserted into the lower guide hole, water flow cannot enter the upper space, and all the water flow flows into the lower space, realizing that the first spray head does not discharge water and the second spray head discharges water. On the contrary, the first spray head discharges water and the second spray head does not discharge water. At the same time, by adjusting the depth of insertion of the baffle into the guide hole, the size of the water flow entering the upper space or the lower space can be adjusted, realizing further fine-tuning of the water discharge of the spray head, and greatly improving the qualified rate of the paper finished product.

[0006] Further, an upper guide groove is formed in the side wall of the upper guide hole, and an upper guide protrusion is fixedly arranged on the side wall of the upper baffle. Both the upper guide protrusion and the upper guide groove are T-shaped, and the upper guide protrusion is slidably connected inside the upper guide groove. A lower guide groove is formed in the side wall of the lower guide hole, and a lower guide protrusion is fixedly arranged on the side wall of the lower baffle. Both the lower guide protrusion and the lower guide groove are T-shaped, and the lower guide protrusion is slidably connected inside the lower guide groove.

[0007] Further, the spray aperture of the first spray head is smaller than that of the second spray head; both the first spray head and the second spray head include a stabilizing part and a spray head part. The stabilizing part is fixedly connected to the side wall of the pipe body. A through hole is formed inside the stabilizing part. The inner end of the through hole is communicated with the inner cavity of the pipe body, and the outer end of the through hole is communicated with the spray head part.

[0008] Further, the pipe body, the partition board, the stabilizing part and the spray head part are integrally formed.

[0009] The beneficial effects of the present utility model: By spraying the sizing roller with different spray heads, the effect of adjusting the flow rate of the spray head is realized. When the first spray head sprays on the sizing roller, the spraying flow rate is a large flow rate and a fine water flow spray. When the second spray head sprays on the sizing roller, the spraying flow rate is a small flow rate and a thick water flow spray. Through the setting of the adjusting component, it is possible to quickly and flexibly adjust whether the first spray head discharges water or the second spray head discharges water, which is convenient and fast. Through the setting of the driving device, when the first spray head discharges water, the driving device drives the pipe body to rotate, so that the first spray head faces the sizing roller; when the second spray head discharges water, the second spray head faces the sizing roller, mechanically realizing the adjustment of the spray head, which is labor-saving and easy, and the positioning accuracy after adjustment is high. By adjusting the depth of insertion of the baffle into the guide hole, the size of the water flow entering the upper space or the lower space can be adjusted, realizing further fine-tuning of the water discharge of the spray head, and greatly improving the qualified rate of the paper finished product.
