Abstract
Description
Technical Field
[0001] The present application relates to the technical field of papermaking equipment, and in particular to a papermaking equipment and a glue spraying device thereof. Background Art
[0002] The paper reel is located at the end of the paper machine and is used to roll the paper web into a paper roll. The performance difference of the paper reel directly affects the winding tightness and quality of paper or paperboard and the production efficiency of the paper machine, and affects the storage and subsequent processing performance. Modern paper reels have realized the automatic replacement of paper rolls, which reduces the waste paper loss caused by paper roll replacement and reduces the labor intensity of operators. Usually, a storage rack for empty paper rolls is provided above the front of the paper reel cylinder. The paper reel cylinder is hung on the frame. When needed, the cylinder pushes the manipulator to connect the roll upward. After connecting the roll, the cylinder of the paper reel slowly retracts the piston rod and puts the paper reel into the fork arm to complete the roll connection action. When replacing the paper roll, the program control system is used to automatically replace the paper roll in the order of paper feeding, rolling, paper rolling and moving the paper roll.
[0003] The current mainstream paper roll handover process is to first cut the paper into triangular strips through a water needle, and then stick the head of the strip on the paper reel with tape. The triangular strip is then curled on the paper reel. Then the paper roll gradually grows to a certain size. When the paper roll reaches the finished roll specifications, the finished paper is cut into triangular strips and the above steps are repeated to complete the handover and roll changing action.
[0004] However, during the paper roll handover process, the tape stuck on the paper roll cylinder needs to be manually stuck, and there are strict requirements on the position and type of the tape. The paper machine has failed to change rolls many times due to problems such as inaccurate tape position, forgotten tape, and tape failure, causing paper machine failure and shutdown, resulting in huge losses. At the same time, the price of special tape is high, with each roll of tape costing as much as 3k-5k yuan. The high tape loss rate results in a large amount of loss cost every day.

[0035] See also Figure 7 , Figure 7 Schematic diagram of the control principle of the glue spraying device of the present application, the glue spraying device 10 also includes an air source system 400 and a glue supply system 500. The air source system 400 includes an air pump 410 and an air guide tube 420, and the air pump 410 is connected to the nozzle 300 through the air guide tube 420.

The glue storage tank 510 is used to store glue liquid, and the glue storage tank 510 is connected to the nozzle 300 through the glue guide tube 530. The feed pump 520, the pressure gauge 550 and the solenoid valve 540 are respectively arranged on the glue guide path of the glue guide tube 530, and are used to provide glue guide power, pressure detection and control switch.
[0036] Optionally, the glue spraying device in the embodiment of the present application may further include a control unit (such as a PLC, etc.) for controlling the working process of the air source system 400 and the glue supply system 500. The detailed features of this part are within the scope of understanding of those skilled in the art and will not be described in detail here.
[0037] The glue spraying device for papermaking equipment provided in the embodiment of the present application can realize the glue spraying position and glue spraying angle of the nozzle by designing a structure of an adjustment component, and has the characteristics of simple structure and convenient adjustment. The glue spraying device can effectively solve the problems of paper machines repeatedly caused by inaccurate tape position, forgotten tape, and tape failure.
[0038] In addition, the present application also provides a papermaking device, see Figure 8 , Figure 8It is a partial structural diagram of an embodiment of the papermaking equipment of the present application, wherein the papermaking equipment may include a paper reel 20 and the glue spraying device 10 in the aforementioned embodiment. In addition, other structural features of the papermaking equipment or the paper reel are within the scope of understanding of those skilled in the art and will not be described in detail here.
[0039] Among them, the air source system 400 and the glue supply system 500 of the glue spraying device 10 are the working core of the automatic glue spraying process. When the papermaking equipment is turned on, the glue liquid is pushed into the nozzle 300 under the simultaneous action of the air source system 400 and the glue supply system 500, and is sprayed out from the nozzle 300 according to the set position, evenly distributed on the surface of the paper web 30, and adhered to the paper winding cylinder 20 along with the paper web 30.
[0040] The paper roll handover process is to first cut the paper web into triangular paper strips through a water needle, and then the head of the paper strip is glued to the paper roll cylinder by the glue sprayed by the glue spraying device. The triangular paper strip is also curled on the paper roll cylinder, and then the paper roll gradually increases until it reaches the preset size. After the equipment is installed, the failure of the triangular paper strip to be glued and rolled up will be reduced by about 95%, the tape cost loss rate will be reduced by about 80%, and the labor intensity will be greatly reduced. Good working results have been achieved in actual production.
[0041] The paper rolling process of the papermaking equipment is as follows: when the program starts to control the water needle to cut out triangular paper strips, the nozzle 300 is controlled to be in an open state through the air source system 400, and the solenoid valve 540 is closed at the same time, the feed pump 520 is in a normally open state, and the glue in the glue storage tank 510 is sprayed out from the nozzle 300 under the action of the feed pump 520.
[0042] After the glue spraying action is completed, the nozzle 300 is controlled to be in a closed state through the air source system 400, and the solenoid valve 540 is opened at the same time. The feed pump 520 is still in an open state, and the glue in the glue storage tank 510 is circulated back to the glue storage tank 510 through the feed pump 520, the pressure gauge 550, and the solenoid valve 540. When the glue storage tank 510 is in a circulation or spraying state, the pipeline pressure is determined by the pressure gauge 550, and the power of the feed pump 520 can be adjusted to increase or decrease the pipeline pressure.
[0043] The glue spraying device uses a high-pressure pump and a nozzle to spray liquid glue onto the surface of the iron core or paper head instantly at the time of roll change, solving the problem of low efficiency and easy paper breakage when using manual tape sticking, and also fundamentally reduces the labor intensity to realize automatic roll change.
[0044] The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
