Description

Technical Field

[0001] This utility model relates to the field of dryer alignment technology, specifically to an alignment device for a horizontal secondary impregnation dryer. Background Technology

[0002] A horizontal secondary impregnation dryer is a device for secondary impregnation and drying of materials. During operation, the material belt is prone to deviation due to various factors such as uneven material distribution, equipment vibration, and roller wear. The deviation adjustment device of the horizontal secondary impregnation dryer is an important device to prevent the material belt from deviating during the operation of the dryer.

[0003] The prior art discloses a horizontal secondary impregnation dryer alignment device with application number 201821654296.9, including an upper frame, a lower frame, an alignment roller one, and an alignment roller two. The upper frame is connected to a connecting rod via a ball bearing one, the lower frame is connected to the connecting rod via a ball bearing two, the upper frame and the lower frame are connected via a ball bearing three, the connecting rod is connected to a hinge connection one, the hinge connection one is connected to a lead screw, the lead screw is connected to a lead screw sleeve, the lead screw sleeve is connected to hinge connection two on one side, and the upper end is connected to a small-power synchronous motor. Hinge connection two is connected to the upper frame. This device has photoelectric sensors on both sides of the paper web to detect the position of the paper web edge. The detection structure controls the rotation direction of the synchronous motor. By controlling the forward and reverse rotation of the motor, the lead screw moves forward or backward, thereby achieving simultaneous rightward or leftward offset of the upper frame, i.e., alignment roller one and alignment roller two.

[0004] The aforementioned device uses a photoelectric sensor to detect the position of the paper web edge and adjusts the swing arm to correct the material deviation. However, the device relies on a single photoelectric sensor for detection, which is insufficient to solve the fundamental problem of deviation and cannot identify potential deviation risks. As a result, the device is not effective in use and needs to be improved. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4 The present invention provides the following technical solution: a horizontal secondary impregnation dryer adjustment device, including a guide mechanism 1 and an adjustment mechanism 2, wherein the adjustment mechanism 2 is movably connected inside the guide mechanism 1.

[0024] The adjustment mechanism 2 includes a correction unit and a monitoring unit. The correction unit is movably connected inside the guide mechanism 1, and the monitoring unit is located inside the guide mechanism 1.

[0025] The guiding mechanism 1 consists of a support frame 101, a guide frame 102, a transmission port 103, a slide rail 104, a hydraulic cylinder 105, and a hydraulic telescopic rod 106. The guide frame 102 is fixedly connected to the top of the support frame 101. The transmission port 103 is opened on both sides of the guide frame 102. The slide rail 104 is fixedly connected to the inside of the guide frame 102. The hydraulic cylinder 105 is fixedly connected to the outside of the guide frame 102. The hydraulic telescopic rod 106 is movably connected to the output end of the hydraulic cylinder 105 and the inside of the slide rail 104, and plays the role of bearing and transmitting.

[0026] The correction unit consists of a correction frame 201, a first electric lifting rod 202, a pressing roller 203, and a spring roller 204. The correction frame 201 is movably connected to the inside of the slide rail 104 and fixedly connected to the output end of the hydraulic telescopic rod 106. The first electric lifting rod 202 is movably connected to the inner top of the correction frame 201, and the pressing roller 203 is rotatably connected to the bottom of the first electric lifting rod 202. The surfaces of the pressing roller 203 and the spring roller 204 are provided with a flexible rubber layer to improve the conductivity stability of the impregnated paper, reduce slippage of the impregnated paper, and reduce deviation. The spring roller 204 is movably connected to the inner bottom of the correction frame 201 to adjust the deviation. The monitoring unit consists of a horizontal plate frame 211, a second electric lifting rod 212, a connecting block 213, a tension roller 214, and an infrared ranging sensor 215. The horizontal plate frame 211 is fixedly connected to the inside of the guide frame 102, and the second electric lifting rod 212 is movably connected to the horizontal plate frame 211. At the top, the connecting block 213 is fixedly connected to the extension end of the second electric lifting rod 212. A rotating shaft is provided on the side of the connecting block 213, and a pressure detection rod is provided on the surface of the rotating shaft. The tension roller 214 is fixedly connected to the surface of the pressure detection rod, which facilitates the detection of the transmission stability of the impregnated paper through the pressure detection rod. It can detect potential deviation risks in time and make timely correction adjustments. The tension roller 214 is rotatably connected to the side of the connecting block 213. Two sets of tension rollers 214 are provided and distributed on the left and right sides of the connecting block 213, which facilitates the identification of pressure at both edges of the impregnated paper through the tension roller 214. When the pressure at one end exceeds the pressure at the other end, potential deviation risks can be quickly detected, improving the use effect. The infrared ranging sensor 215 is fixedly connected to the inner wall of the guide frame 102, which plays the main role in monitoring the position of the impregnated paper. It can improve the monitoring effect through the combination of pressure transmission and infrared ranging.

[0027] In use, the impregnated paper enters through the transmission port 103 of the guide mechanism 1. The slide rail 104 inside the guide frame 102 provides a movement track for the alignment mechanism 2. The hydraulic cylinder 105 drives the hydraulic telescopic rod 106 to move the alignment mechanism 2 on the slide rail 104. In the monitoring unit, two sets of tension rollers 214 distributed on the left and right sides of the connecting block 213 detect the pressure on both sides of the impregnated paper's edges through the pressure detection rod. When the pressure is uneven, a preliminary judgment of potential deviation risk is made. At the same time, the infrared ranging sensor 215 monitors the position of the impregnated paper in real time. The combination of the two provides data for alignment. Once deviation is detected, the control system activates the correction unit. The hydraulic telescopic rod 106 pushes the alignment frame 201 to move. At the same time, the first electric lifting rod 202 adjusts the height of the pressing roller 203, so that the pressing roller 203 with a flexible rubber layer on its surface and the spring roller 204 apply appropriate pressure to the impregnated paper, adjusting its running direction, thereby realizing the alignment of the impregnated paper.
