Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper drying equipment technology, specifically a practical paper drying and feeding device. Background Technology
[0002] The paper drying section is an important part of the paper machine. It is located after the press section and before the calender and winding sections. Its core task is to use heat energy to further dehydrate and dry the wet paper sheet, which still contains about 60% moisture after pressing, to the moisture content required for the finished paper (usually 4%-10%).
[0003] In the prior art, Chinese Patent Application No. CN201911152069.5 discloses a paper machine drying cylinder, including a roller shell. Both sides of the roller shell are fixedly connected to shell end caps. Bearing seats are fixedly installed on the disjoint surfaces of the two shell end caps. A support column is fixedly installed at the bottom of the bearing seat. A roller bearing is movably installed inside the bearing seat. A steam pipe extending to the left side of the left bearing seat is movably installed inside the left roller bearing. A steam connector communicating with the steam pipe is fixedly connected to the bottom of the steam pipe. A condenser pipe extending to the right side of the right bearing seat is movably installed inside the right roller bearing.
[0004] Based on the above information, it can be seen that the drying cylinder is the core equipment in the existing paper drying process. However, in actual use, the dried paper is guided by paper guide ropes. But as the speed of the machine gradually increases, guiding the paper between the drying cylinder groups becomes more difficult. This is mainly because when the speed of the paper strip is too high, it is easy to wrinkle during the fall in the open area, making it difficult for the paper guide ropes at the rear to catch the paper strip. Manually blowing the paper with air pipes often requires skilled workers, but at the same time, because manual operation requires inserting the air pipe into the paper guide ropes, it increases the safety risks for personnel. Utility Model Content
[0005] The purpose of this invention is to provide a practical paper drying and feeding device to solve the problems mentioned in the background art, such as the cumbersome and potentially dangerous paper feeding process.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a practical paper drying and guiding device, comprising a support frame fixedly installed in a papermaking equipment, a drying cylinder rotatably installed inside the support frame, and guide wheels for guiding the paper guiding rope rotatably installed on the front and rear sides of the support frame, an mounting frame fixedly installed on the left side of the support frame, and a peeling scraper in contact with the surface of the drying cylinder installed on the upper end of the mounting frame, an upper air blowing nozzle and a lower air blowing nozzle installed on the outer side of the mounting frame, and two of each type of nozzle are symmetrically arranged, and a controller for controlling the upper air blowing nozzle and the lower air blowing nozzle is fixedly installed on the outer front side of the support frame.
[0007] Preferably, the nozzle of the upward blowing nozzle is parallel to the stripping scraper, and the nozzle of the downward blowing nozzle faces the paper guide rope.
[0008] Preferably, a first connecting pipe and a second connecting pipe are fixedly installed on the side of the controller, with the first connecting pipe connected to the upper air nozzle and the second connecting pipe connected to the lower air nozzle.
[0009] Preferably, the controller has a control knob on the front side for controlling the on / off state of the first and second connecting pipes, and an air supply pipe connected to the air supply device is installed at the lower end of the controller.
[0010] Preferably, the downward blowing nozzle is connected to a fixing block fixedly installed on the outer surface of the mounting frame, and connecting rods are fixedly installed at both ends of the fixing block.
[0011] Preferably, a positioning ball is fixedly installed at the front end of the connecting rod, and the positioning ball is engaged with the positioning groove.
[0012] Preferably, the positioning grooves are evenly spaced and uniformly opened on the side of the downward blowing nozzle.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This practical paper drying and feeding device adopts a novel structural design, the specific details of which are as follows:
[0014] 1. Set up an upper air nozzle and a lower air nozzle. Use the airflow blown by the upper air nozzle to blow towards the peeling blade position to assist the paper to peel off from the surface of the drying cylinder. At the same time, the lower air nozzle blows the lower end of the peeled paper towards the paper guide rope position to achieve the purpose of automatic paper feeding.
[0015] Furthermore, during the paper feeding process, the operator only needs to operate the control knob on the outside of the controller, without having to put their body into the device. The overall operation is more convenient and faster, and because it does not require insertion, it is safer.
[0016] 2. The downward air nozzle is connected to the fixed block, and the two can rotate relative to each other. The angle of the downward air nozzle can be finely adjusted to meet different actual working conditions, so as to make the paper feeding more accurate.
[0017] Furthermore, connecting rods are provided at both ends of the fixing block, and the top ball at the top of the connecting rod engages with the positioning groove opened on the side of the downward blowing nozzle to fix the downward blowing nozzle. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1: Please refer to Figures 1-3To facilitate paper feeding, this embodiment provides the following technical solution, specifically: a support frame 1 fixedly installed in the papermaking equipment; a drying cylinder 2 rotatably installed inside the support frame 1; guide wheels 3 for guiding the paper feeding rope 4 rotatably installed on the front and rear sides of the support frame 1; a mounting frame 5 fixedly installed on the left side of the support frame 1; a peeling scraper 6 in contact with the surface of the drying cylinder 2 installed on the upper end of the mounting frame 5; an upper air blowing nozzle 7 and a lower air blowing nozzle 8 installed on the outer side of the mounting frame 5; two upper air blowing nozzles 7 and two lower air blowing nozzles 8 are symmetrically arranged; and the front side of the support frame 1... A controller 9 is fixedly installed to control the upper air nozzle 7 and the lower air nozzle 8. The nozzle position of the upper air nozzle 7 is parallel to the stripping scraper 6, and the nozzle position of the lower air nozzle 8 faces the paper guide rope 4. A first connecting pipe 10 and a second connecting pipe 11 are fixedly installed on the side of the controller 9. The first connecting pipe 10 is connected to the upper air nozzle 7, and the second connecting pipe 11 is connected to the lower air nozzle 8. A control knob 13 for controlling the on and off of the first connecting pipe 10 and the second connecting pipe 11 is installed on the front side of the controller 9, and an air supply pipe 12 connected to the air supply device is installed at the lower end of the controller 9.
[0027] When the paper machine is working, the damp paper is located outside the drying cylinder 2. The drying cylinder 2 is used to dry the paper. After drying, the front end of the paper rotates to the peeling blade 6. The peeling blade 6 peels the paper off the surface of the drying cylinder 2. At this time, the operator operates the control knob 13 in the external controller 9 on the front side of the support frame 1. The control knob 13 opens the passage of the first connecting pipe 10. At this time, the airflow from the air supply pipe 12 is delivered to the upward blowing nozzle 7 through the first connecting pipe 10 and sprayed out. The upward blowing nozzle 7 blows the paper to assist in the peeling. After peeling, the front end of the paper hangs down naturally. At this time, the control knob 13 is opened again to open the passage of the second connecting pipe 11. The airflow is delivered to the downward blowing nozzle 8 through the second connecting pipe 11 and sprayed out. The downward blowing nozzle 8 blows the front end of the paper, causing the front end of the paper to swing to the position of the paper guide rope 4 to achieve the purpose of automatic paper feeding. This process can be operated from the outside, which is convenient, fast and has a high degree of safety.
[0028] Example 2: Please refer to Figures 4-6 In order to adjust the nozzle angle, this embodiment provides the following technical solution, which specifically discloses that: the down-blowing nozzle 8 is connected to the fixing block 14 fixedly installed on the outer surface of the mounting bracket 5, and the fixing block 14 is fixedly installed with connecting rods 15 at both ends. The front end of the connecting rod 15 is fixedly installed with a positioning ball 16, and the positioning ball 16 is engaged with the positioning groove 17. The positioning groove 17 is evenly and evenly opened on the side of the down-blowing nozzle 8.
[0029] Before the device is put into operation, the staff adjusts the angle of the downward blowing nozzle 8 according to the actual production situation (such as the height of the paper after peeling off). The downward blowing nozzle 8 rotates relative to the fixed block 14. After the angle is determined, the positioning ball 16 at the front end of the connecting rod 15 on both sides of the fixed block 14 is inserted into the positioning groove 17 at the corresponding position to achieve locking and fixing.
