Description

Technical Field

[0001] This utility model relates to the field of papermaking machinery and equipment technology, specifically a double-roll press device for a papermaking machine. Background Technology

[0002] In the papermaking process, the pressing process is a key step in paper dehydration. Its main function is to apply pressure to the wet paper sheet through the press rollers to squeeze out the water, thereby increasing the dryness of the paper and reducing the energy consumption of subsequent drying processes.

[0003] In the actual operation of existing two-roll press units, wet paper sheets are dehydrated under the squeezing action of two press rolls. During this process, some wet paper sheets may be damaged due to external factors (such as uneven raw material distribution or slight equipment vibration), and the resulting paper scraps easily adhere to the surface of the press rolls. If these attached paper scraps are not cleaned in time, they will affect the wet paper sheets entering the subsequent pressing process as the press rolls continue to operate, leading to quality defects such as watermarks and wrinkles in the finished paper, ultimately reducing the overall production quality of the paper.

[0004] Therefore, this utility model provides a double-roll press device for a papermaking machine to solve the above problems. Utility Model Content

[0014] Beneficial effects This invention provides a double-roll press device for a papermaking machine. Compared with the prior art, it has the following advantages: (1) The double-roll press device of this paper machine can flexibly adjust the extension length and height of the doctor blade through the coordinated cooperation of the adjustment component and the scraping component, so that users can make precise adaptation according to the actual scraping position requirements. When the equipment needs to be started, the rotating motor is started first, and its output shaft will drive the lead screw to rotate synchronously; since the sliding block and the lead screw are threadedly connected, the rotation of the lead screw will drive the sliding block to move up and down along the guide rod, thereby driving the scraping component to adjust to the target height. After the height positioning is completed, the fixed frame is moved by the hydraulic rod, so that the scraping component reaches the preset horizontal position; then the scraping motor is started, and its output shaft will drive the second connecting rod on one side to move, and the first connecting rod fixedly connected to the second connecting rod will move in conjunction, and finally adjust the doctor blade to an angle that is convenient for efficient scraping. In this process, by controlling the rotation of the first and second pressure rollers, paper scraps, dust and other impurities attached to the surface of the two pressure rollers can be scraped off simultaneously. This design can effectively avoid the quality defects such as watermarks and wrinkles caused by the residue of impurities in the finished paper, and ultimately improve the overall production quality of paper.

[0015] (2) The double-roll press device of this paper machine, through the coordinated operation of the water collection component and the press component, can efficiently collect the water generated during the pressing process, prevent water from dripping onto the surface of the device and causing rust, and can also press the paper. This can significantly reduce the energy consumption in the paper drying stage, reduce production costs, enhance the paper strength and usability, and ultimately improve the quality of the finished product. When the drive motor is started, the output shaft of the drive motor drives the No. 2 gear to rotate, which in turn causes the No. 1 gear, which is meshed with the No. 2 gear, to rotate in the opposite direction, thereby pressing the paper between the No. 1 and No. 2 press rolls. The water generated during the pressing process will naturally flow into the drain outlet and be collected in the sliding drawer through the drain outlet. When the water flows through the drawer, it will first filter out the impurities mixed in the water through the drain outlet, and then the clean water will enter the water collection tank for storage through the drain outlet. When it is necessary to deal with the water in the water collection tank, the outlet of the water collection tank can be connected to the external connection pipe, and the solenoid valve built into the outlet can be opened to discharge the collected water, realizing the recycling of water resources. In addition, when impurities accumulate to a certain extent inside the pull-out drawer, the user can pull the drawer handle outwards to allow the drawer to slide along the slide rails and be pulled out smoothly, thus making it convenient to clean the impurities remaining inside the filter.

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.

[0019] Example 1: Please see Figure 1-5 A two-roll press device for a papermaking machine, comprising: The operating table 1 has two drain outlets 2 on its surface. A mounting frame 5 is fixedly connected to the top surface of the operating table 1. A reinforcing rib 3 is provided on the bottom side of the mounting frame 5, and the bottom surface of the reinforcing rib 3 is fixedly connected to the top surface of the operating table 1. A water collection component 4 is fixedly connected to the bottom surface of the operating table 1 and is used to collect water generated during pressing. A pressing component 6 is located inside the mounting frame 5 and is used to press the paper. An adjusting component 7 is located on the top surface of the operating table 1 and has a scraping component 8 on its surface. The adjusting component 7 includes an adjusting frame 71, fixing bolts 72, four first-order fixing blocks 73, a lead screw 75, and a sliding block 77. The adjusting frame 71 is connected to the top surface of the operating table 1 by the fixing bolts 72. The four first-order fixing blocks 73 are fixedly connected to both ends of the surface of the adjusting frame 71, and guide rods 78 are fixedly connected to the inner walls of the two first-order fixing blocks 73 at each end. A second fixing block 74 is fixedly connected to the bottom of the middle part of the surface of the adjusting frame 71. A rotating motor 76 is provided on the upper part of the adjusting frame 71. The output shaft of the rotating motor 76 is fixedly connected to the lead screw 75. The bottom end of the lead screw 75 is rotatably connected to the surface of the second fixing block 74. The two ends of the sliding block 77 are slidably connected to the guide rod 78 and threadedly connected to the outer wall of the lead screw 75. The scraping assembly 8 includes a connecting piece 81 and a scraping motor 84. The connecting piece 81 is provided on the surface of the sliding block 77. A hydraulic rod 82 is fixedly connected to the surface of the connecting piece 81. A fixing frame 83 is fixedly connected to the output end of the hydraulic rod 82. A second connecting rod 87 is rotatably connected to both ends of the fixing frame 83. A first connecting rod 85 is fixedly connected to the outer wall of the two second connecting rods 87. A scraper 86 is fixedly connected to one end of the two first connecting rods 85. The scraping motor 84 is fixedly installed on one side of the fixing frame 83. The output shaft of the scraping motor 84 is fixedly connected to the second connecting rod 87 on the corresponding side.

[0020] In this embodiment, by adjusting component 7 and scraping component 8, the extension length and height of scraper 86 can be adjusted in cooperation, allowing the user to adjust the scraping position as needed. When needed, simply start the rotary motor 76. The output shaft of the rotary motor 76 drives the lead screw 75 to rotate, causing the sliding block 77, which is threadedly connected to the lead screw 75, to rise or fall with the rotation of the lead screw 75. This allows the sliding block 77 to slide on the surface of the guide rod 78, thereby moving the scraping component 8 to a suitable height. Then, the hydraulic rod 82... The fixed frame 83 is pushed to a suitable position, and then the scraping motor 84 is started. The output shaft of the scraping motor 84 drives the second connecting rod 87 on one side to move, thereby moving the first connecting rod 85, which is fixedly connected to the second connecting rod 87, to a suitable position. This causes the scraper 86 to move to an angle that facilitates scraping. Then, by adjusting the rotation of the first pressure roller 65 and the second pressure roller 66, paper scraps or dust attached to the surface of the first pressure roller 65 and the second pressure roller 66 can be scraped off, avoiding quality defects such as watermarks and wrinkles in the finished paper, and ultimately reducing the overall production quality of the paper.

[0021] Example 2: Please see Figure 2-5 This embodiment provides a technical solution based on Embodiment 1: the pressing assembly 6 includes a motor bracket 61, a first gear 63, a first pressure roller 65, and a second pressure roller 66. The motor bracket 61 is fixedly connected to the side of the mounting frame 5. A drive motor 62 is fixedly connected to the inner side of the motor bracket 61. A second gear 64 is fixedly connected to the output shaft of the drive motor 62. The upper end of the second gear 64 meshes with the first gear 63. The first gear 63 is fixedly connected to the second pressure roller 66. The second pressure roller 66 is rotatably connected to the inner wall of the mounting frame 5. The second gear 64 is fixedly connected to one end of the first pressure roller 65. The pressure roller 65 is rotatably connected to the inner wall of one side of the mounting frame 5. The water collection assembly 4 includes a water collection tank 41 and a push-pull drawer 47. The water collection tank 41 is fixedly installed on the bottom surface of the operating table 1. The water collection tank 41 is connected to the drain outlet 2. The inner walls on both sides of the water collection tank 41 are fixedly connected to the slide grooves 43. The outer walls of the slide grooves 43 are slidably connected to the slide rails 44. The slide rails 44 are set on both sides of the push-pull drawer 47.

The bottom surface of the water collection tank 41 is fixedly connected to the water outlet 42. The inside of the water outlet 42 is equipped with a solenoid valve.

[0022] In this embodiment, the water collection component 4 and the pressing component 6 can collect the water generated during the pressing process, preventing water from falling onto the surface of the device and causing rust. Simultaneously, pressing the paper significantly reduces drying energy consumption, lowers production costs, improves paper strength and usability, and enhances finished product quality. The drive motor 62 is started, and its output shaft drives the second gear 64 to rotate, causing the first gear 63, which meshes with the second gear 64, to rotate in the opposite direction. This presses the paper between the second pressure roller 66 and the first pressure roller 65, and the water released from the pressed paper flows to… In drain outlet 2, the water generated during the pressing process flows into the sliding drawer 47 through drain outlet 2. Impurities in the water flow can be filtered through drain outlet 45. At the same time, the water flow enters the water collection tank 41 through drain outlet 45, and then connects to the outside through the water outlet 42. Then, the solenoid valve inside the water outlet 42 is opened to discharge the water collected in the water collection tank 41, thereby achieving the effect of water resource recycling. Then, the user can pull the handle 46 outward, which will cause the sliding drawer 47 to slide on the slide rail 44 on the slide groove 43, thereby pulling the sliding drawer 47 outward, and then cleaning the filtered impurities inside the sliding drawer 47.
