Description

Technical Field

[0001] This utility model relates to the field of kraft paper equipment technology, specifically a kraft paper uniformity measuring device. Background Technology

[0002] Kraft paperboard is one of the main types of paper used for cardboard boxes. It is commonly used to manufacture various packaging boxes, especially export packaging boxes and packaging boxes for high-end domestic goods. It has many unique properties: tough texture, high burst strength, ring crush strength and tear strength, as well as good water resistance. In addition to its use in packaging boxes, kraft paperboard is also widely used in clothing pattern making, design and drafting, and other fields. Therefore, kraft paperboard is a widely used paper type in the packaging industry. Its unique properties and diverse uses make it the preferred material for many industries.

[0003] A search of the China Patent Network revealed a patent (publication number: CN222298712U) that discloses a kraft paper uniformity measuring device. This device uses a lifting structure and a driving structure to move the outer surface of the roller on the outer surface of the kraft paper. Therefore, when the thickness of the kraft paper is uneven, the height of the roller will change. The pen tip at one end of the slider will follow the change and draw lines on the surface of the LCD handwriting tablet. The lines can reflect the overall thickness of the kraft paper, which can increase the accuracy of the test data and thus better evaluate the uniformity of the kraft paper.

[0004] However, the above technical solution still has certain defects. The device moves the outer surface of the roller on the outer surface of the kraft paper to detect the thickness of the kraft paper. However, when the roller moves, the kraft paper may be deflected due to friction, which will affect the detection effect of the paper. At the same time, after the detection is completed, the paper needs to be removed and then a new paper needs to be put in for detection, which is slow. Therefore, a kraft paper uniformity measuring device is proposed. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A device for measuring the uniformity of kraft paper, such as Figure 1-6 As shown, it includes a worktable 100, and a replacement component 200 is slidably connected to the top of the worktable 100;

[0026] The replacement component 200 includes a plate 210 slidably connected to the top of the workbench 100. There are two sets of plate 210, with another set of plate 210 extending to one side of the workbench 100. A first pressure block 230 is attached to one side of the top of both sets of plate 210. A first spring 240 installed inside the plate 210 is provided on both sides of the bottom of the first pressure block 230. A second pressure block 250 is slidably connected to the top of the plate 210 away from the first pressure block 230. A moving block 260 is fixed on both sides of the bottom of the second pressure block 250. A second spring 270 is installed inside the moving block 260. The second spring 270 is fixedly connected to the second pressure block 250. A T-shaped slider 280 is fixed on both sides of the bottom of both sets of plate 210. A groove 281 for the T-shaped slider 280 to move is provided at the top of the workbench 100.

[0027] By pushing the second pressure block 250 towards the first pressure block 230 until they are in contact, and then lifting the first and second pressure blocks 230 and 250, the kraft paper to be tested is laid flat on the plate 210, with one end of the kraft paper directly under the first and second pressure blocks 230. The two sets of pressure blocks are then released; the first spring 240 applies force to the first pressure block 230, fixing one end of the kraft paper. Pulling the second pressure block 250, which is in contact with the kraft paper, moves it away from the first pressure block 230, effectively flattening the kraft paper and preventing... When wrinkles occur during uniformity testing, the second pressure block 250 is used to fix the other end of the kraft paper to prevent the roller 160 from shifting when it is in contact with the kraft paper, which would affect the testing effect. When the uniformity of the kraft paper is tested, the next set of kraft paper is placed on another set of flat plates 210. After the previous set of kraft paper is tested, the pull plate 220 is pulled to move the first set of flat plates 210 off the worktable 100, and the second set of flat plates 210 is moved in for testing. By alternating the use of the two sets of flat plates 210, the testing efficiency of the kraft paper is effectively enhanced, thereby improving the work efficiency.

[0028] Please refer to this carefully. Figures 1 to 3An L-shaped connecting plate 110 is fixed to one side of the top of the workbench 100. A support plate 120 is installed on the top of the L-shaped connecting plate 110. An electric push rod 130 is provided on the top of the support plate 120. A U-shaped plate 140 is fixed to the end of the movable rod of the electric push rod 130. A movable frame 150 is fixed to the bottom of the U-shaped plate 140. Movable grooves 151 are opened on both sides of the movable frame 150. A roller 160 is slidably connected inside the movable groove 151. A pen tip 161 is provided at one end of the roller 160, and a square block 170 is provided at the other end of the roller 160. A liquid crystal handwriting tablet body 162 is installed at one end of the pen tip 161. A threaded screw 180 is provided through the square block 170. A servo motor 190 is provided at one end of the threaded screw 180 to drive its rotation. A fixing plate 191 is provided at the end of the servo motor 190 away from the threaded screw 180. The fixing plate 191 is slidably connected to the movable frame 150.

[0029] By activating the electric push rod 130, the U-shaped plate 140 is moved, causing the U-shaped plate 140 to lower the movable frame 150 and roller 160 until the roller 160 is in contact with the surface of the kraft paper. Then, the servo motor 190 is activated, which drives the square block 170 to move through the threaded screw 180. The square block 170 drives the roller 160 and pen tip 161 to move along the movable groove 151. During the movement, the pen tip 161 will draw a moving curve on the LCD handwriting tablet body 162. When encountering uneven thickness of the kraft paper, the height of the roller 160 will change. Thus, the overall thickness of the kraft paper can be reflected by the lines, which can help increase the accuracy of the detection data. After the thickness of the kraft paper is detected, the uniformity of its thickness can be judged by the horizontality of the lines on the surface of the LCD handwriting tablet body 162. The thickness value of the entire kraft paper can then be obtained, thus better evaluating the uniformity of the kraft paper.

[0030] Please refer to this carefully. Figure 2 and Figure 3 The roller 160 can move up and down inside the movable groove 151.

[0031] The roller 160 can slide inside the movable groove 151 and move at the same time, which allows for better detection of the uniformity of the kraft paper through the cooperation between the pen tip 161 and the main body 162 of the LCD handwriting tablet.

[0032] Please refer to this carefully. Figures 4 to 6 A pull plate 220 is fixed on one side of the plate 210. The inner side of the pull plate 220 is in contact with one side of the worktable 100. The top two sides of the plate 210 are provided with moving grooves 261 for the moving block 260 to slide. Limiting plates 271 are fixed on both sides of the top of the moving block 260. The two ends of the second pressing block 250 are engaged between the two sets of limiting plates 271.

[0033] By attaching the pull plate 220 to one side of the worktable 100, the movement distance of the flat plate 210 pushed onto the worktable 100 can be limited. By setting the limit plate 271, it is easier to pull the second pressure block 250 to move on the flat plate 210.

[0034] In use, the first spring 240 applies force to the first pressure block 230 to fix one end of the kraft paper. Then, the second pressure block 250 is pulled to flatten the kraft paper, effectively preventing wrinkles during uniformity testing. This continues until the second pressure block 250 fixes the other end of the kraft paper, preventing the roller 160 from shifting when it moves against the kraft paper, thus affecting the testing effect. When performing uniformity testing on the kraft paper, the next set of kraft paper is placed on another set of flat plates 210. After the previous set of kraft paper has been tested, the pull plate 220 is pulled, causing the first set of flat plates 210 to move off the worktable 100, and the second set of flat plates 210 to move in for testing. By alternating the use of two sets of flat plates 210, the detection efficiency of kraft paper is effectively enhanced, thereby improving work efficiency. By activating the electric push rod 130, the roller 160 is made to fit against the surface of the kraft paper. Then, the servo motor 190 is activated to drive the roller 160 and the pen tip 161 to move along the movable groove 151. During the movement, the pen tip 161 will draw a moving curve on the main body 162 of the LCD handwriting tablet. When encountering uneven thickness of kraft paper, the height of the roller 160 will change, so that the overall thickness of the kraft paper can be reflected by the lines, which can help increase the accuracy of the detection data. The parts not involved in this device are the same as or can be implemented by existing technology.
