Description

Technical Field

[0001] This utility model relates to the field of paper machine safety protection technology, and in particular to a paper machine pressure roller flip-over safety protection device. Background Technology

[0002] A roll-reversible paper machine is a type of papermaking equipment equipped with a roll-reversible structure in the press section or finishing section. The core of the design is to solve the problem of inconvenient operation during maintenance, cleaning, and roll replacement of traditional fixed rolls by using the roll-reversible function. At the same time, it ensures production continuity and operational safety. However, when using a roll-reversible paper machine, the roll bearings may wear and the fastening bolts may loosen after long-term operation, which may cause the roll to shift or parts to fall off. The falling off of high-speed rotating parts will form splashes. Since there are no protective objects around the paper machine, the splashes may hit surrounding personnel or equipment. Furthermore, if the paper stuck to the surface of the pressure roller is not cleaned in time, it will cause the paper to continue to entangle. The entangled paper will generate heat through long-term friction, which may reach the ignition point and cause a local fire. At this time, staff need to carry fire extinguishers to the vicinity of the paper machine and manually extinguish the fire. The paper machine may pose a safety hazard while it is in operation.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example: This example provides a reversible safety protection device for the pressure roll of a paper machine. See [link / reference]. Figure 1-4 The system includes a protective frame 1, which is made of Q235 steel plate and bent into shape. A tempered glass window 5 is installed on one side of the protective frame 1. An observation window is opened on one side of the protective frame 1 and inlaid with 8mm thick tempered glass. The edges are sealed with rubber sealing strips to facilitate observation of the operating status of the pressure roller. A power component 2 is set on one side of the protective frame 1 and a moving component 3 is set on the top of the protective frame 1. The power component 2 includes a door panel 201 that is rotated and set on one side of the protective frame 1. When the door panel 201 is in a vertical closed state, it can provide safety protection for the staff. When the door panel 201 is flipped to a horizontal state, it is convenient for the staff to enter the protective frame 1 for maintenance. A rectangular plate 203 is fixedly set on one side of the protective frame 1. A first fixing plate 204 is fixedly set on the top surface of the rectangular plate 203. The paper machine body 4 is set inside the protective frame 1. The power component 2 also includes a cylinder 205 rotatably connected between the two protruding ends of the first fixed plate 204. The cylinder 205 is a GopaMD1200-50, suitable for equipment requiring large thrust and with limited installation space. The piston rod of the cylinder 205 is fixedly provided with a fixing block 206. The power component 2 also includes a pair of second fixed plates 207 fixedly connected to one side of the door panel 201. The two second fixed plates 207 are symmetrically arranged. The fixing block 206 is rotatably connected between the two second fixed plates 207. The power component 2 also includes a mounting plate 202 fixedly installed at the top of the protective frame 1. The door panel 201 is rotatably connected between the two protruding ends of the mounting plate 202. The cylinder 205 is located below the mounting plate 202. Since the cylinder 205 is rotatably connected between the two protruding ends of the first fixed plate 204, there is no obstruction when the cylinder 205 provides power to the door panel 201, so that the door panel 201 can be pushed. See Figure 1-4In the figure, the door panel 201 is in a horizontally open state. When the door panel 201 is horizontally open, the staff can enter the interior of the protective frame 1 to facilitate the staff to maintain the paper machine body 4. After the maintenance is completed, the cylinder 205 is started. The end of the piston rod of the cylinder 205 retracts inward, driving the fixed block 206 to move. Since the fixed block 206 is rotatably connected to the two second fixed plates 207, the door panel 201 moves under the action of the fixed block 206. Since the door panel 201 is rotatably connected to the mounting plate 202, the door panel 201 can be rotated to the vertically closed state. At this time, the door panel 201 is attached to one side of the protective frame 1, thereby shielding one side of the paper machine body 4 and reducing safety hazards. This utility model's flip-up safety protection device for paper machine pressure rollers, through the installation of a power component 2, achieves the function of adding a shield around the main body 4 of the paper machine, preventing splashes generated in the event of a malfunction from hitting surrounding personnel or equipment. The tempered glass window 5 facilitates observation of the operating status of the pressure rollers. The cylinder 205 and the door panel 201 allow the door panel 201 to be flipped from a vertically closed state to a horizontally open state, facilitating maintenance of the main body 4 of the paper machine by the staff.

[0016] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3 As shown, the movable component 3 includes an inverted U-shaped plate 301 slidably disposed at the top of the protective frame 1. Several nozzles 306 arranged in an array are disposed on the inner side of the inverted U-shaped plate 301. The nozzles 306 are used to spray dry powder. The nozzles 306 are directional and angled, and can accurately spray the fire source area. The two protruding ends of the inverted U-shaped plate 301 are fixedly provided with second sliders 302. The top of the protective frame 1 has two symmetrical second sliding grooves. The two second sliders 302 are slidably disposed in the corresponding second sliding grooves. By setting the second sliders 302 and the second sliding grooves, the inverted U-shaped plate 301 can drive the nozzles 306 to move at the upper end of the protective frame 1, so that the nozzles 306 can move to the fire source area of ​​the paper machine body 4 for accurate spraying. A threaded rod 303 is rotatably installed in the second slide groove on one side. The threaded rod 303 is threaded through a second slider 302. A second round rod 304 is fixedly installed in the second slide groove on the other side. The second round rod 304 slides through another second slider 302. By setting the second round rod 304, the inverted U-shaped plate 301 is kept horizontal when moving. The moving part 3 also includes a motor 305 installed inside the protective frame 1. The output shaft of the motor 305 is connected to one end of the threaded rod 303. The model of the motor 305 is JGY-370, which can provide a certain self-locking force and realize forward and reverse switching. By setting the motor 305, power can be provided to the threaded rod 303. This utility model's flip-up safety protection device for papermaking machine pressure rollers, through the setting of a moving part 3, achieves the function of accurately extinguishing fires in the fire source area generated on the papermaking machine body 4. By setting a second slider 302, the inverted U-shaped plate 301 can drive the nozzle 306 to move at the upper end of the protective frame 1, making it easy for the nozzle 306 to move to the fire source area of ​​the papermaking machine body 4 for accurate fire extinguishing. There is no need for staff to carry fire extinguishers to the vicinity of the papermaking machine body 4 to manually extinguish the fire source area, thus reducing safety hazards.

[0017] Specifically, the working principle and operation method of this utility model are as follows: In actual operation, disconnect the power supply to the main body 4 of the paper machine, and then operate as follows; Step 1: Start cylinder 205. The piston end of cylinder 205 extends and pushes the fixing block 206. The fixing block 206 drives the two second fixing plates 207 to move, so that the door panel 201 moves under the action of the fixing block 206. Since the door panel 201 is rotatably connected to the mounting plate 202, the door panel 201 flips upward under the action of cylinder 205 and opens horizontally. Step 2: When a fire is discovered through the tempered glass window 5, start the motor 305, which drives the threaded rod 303 to rotate. The threaded rod 303 drives the second slider 302 to move, which in turn drives the inverted U-shaped plate 301 to move on the protective frame 1, so that the nozzle 306 can evenly spray dry powder onto the paper machine body 4.
