Description

Technical Field

[0001] This utility model relates to the field of honeycomb paperboard production, and in particular to a glue scraping device for a laminating machine used in the production of honeycomb paperboard. Background Technology

[0002] A paper laminating machine is a device used to glue two sheets of paper together. It consists of a paper feeding mechanism, a paper laminating mechanism, and a paper pressing mechanism. During the glue application process in the paper laminating mechanism, excess glue is applied to the paperboard and needs to be cleaned off using a glue scraper. A search of Chinese patents revealed CN218257513U, a scraping mechanism for a paper mounting machine, belonging to the field of scraping technology for paper mounting machines. The mechanism includes a paper mounting machine body with three rotating shafts rotatably mounted inside. One end of each shaft extends through the body, and rollers are mounted on its outer surface. The output shaft of a motor is fixedly connected to one end of one of the shafts. Synchronous pulleys are mounted on one end of the two outer shafts. This scraping mechanism, by setting up scraper blades one and two, utilizes an external glue outlet device connected to the glue inlet pipe. Glue enters the glue outlet frame through a conveying pipe. Combined with the motor driving one of the shafts to rotate, the paper is conveyed, and glue falls onto the paper surface through the glue outlet hole. Excess glue on the paper surface and rollers is cleaned by scraper blades one and two, respectively. The height of scraper blade one can be easily adjusted at any time using an electric push rod, increasing the applicability of the device.

[0003] Existing glue-scraping devices are inconvenient for adjusting the height of the scraper blade. Generally, both ends of the scraper blade are fixed with bolts. When adjusting the height, it is necessary to remove the bolts at both ends of the scraper blade, adjust the scraper blade to the required height, and then fix it again. The adjustment process is cumbersome and it is difficult to ensure that both ends of the scraper blade are level. This makes it inconvenient to use and also inconvenient to replace the scraper blade. Generally, the scraper blade is fixed to the mounting base with multiple bolts. When replacing it, tools are required for disassembly and assembly, which is troublesome, increases the workload, and reduces the efficiency of replacement. In order to solve the above problems, we propose a glue-scraping device for a laminating machine used in the production of honeycomb paperboard. Utility Model Content

[0004] The purpose of this invention is to provide a scraping device for a laminating machine used in the production of honeycomb paperboard. Its advantages are that the height of the scraping plate is easy to adjust and the scraping plate is easy to replace.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a glue scraping device for a laminating machine used in the production of honeycomb paperboard, comprising a fixed frame, two sliding grooves formed on the inner wall of the fixed frame, sliders slidably connected to the inner wall of the sliding grooves, a fixed seat bolted between the two sliders, a screw threaded to the inner wall of the slider, and the screw rotatably connected to the inner wall of the fixed frame, a rotating shaft rotatably sleeved on the inner wall of the fixed frame, a first bevel gear fixedly sleeved at the bottom of the rotating shaft, two bevel gear drive shafts meshing on the surface of the first bevel gear, and the bevel gear drive shafts rotatably sleeved to the inner wall of the fixed frame, a second bevel gear meshing at the other end of the bevel gear drive shaft, and the axis of the second bevel gear fixedly sleeved to the top of the screw.

[0006] By adopting the above technical solution, the rotating turntable causes the rotating shaft to rotate the first bevel gear, the rotation of the first bevel gear causes the bevel gear transmission rod to rotate the second bevel gear, the rotation of the second bevel gear causes the screw to move the slider, and the movement of the slider causes the scraper to move. This method can achieve the purpose of easy height adjustment, reduce the workload, and ensure the level of the scraper.

[0008] By adopting the above technical solution, pressing the pressing head causes the pressing rod to move the locking connector. The movement of the locking connector causes it to disengage from the locking hole, allowing the scraper to be removed and replaced. This method facilitates the replacement of the scraper, reduces workload, improves replacement efficiency, and is convenient to use.

[0009] The present invention is further configured such that: the adjustment mechanism includes an adjustment plate, the adjustment plate is slidably connected to the inner wall of the fixed seat, the top of the adjustment plate is rotatably connected to an adjustment bolt, and the adjustment bolt is threadedly connected to the inner wall of the fixed seat; a second spring is fixedly connected between the adjustment plate and the mounting seat by a spring fixing member.

[0010] By adopting the above technical solution, an adjustment mechanism is set up. Rotating the adjustment bolt causes the adjustment bolt to move the adjustment plate. The movement of the adjustment plate changes the elastic force of the second spring, which in turn changes the pressure between the scraper and the honeycomb paperboard, thereby adjusting the pressure of the scraper and ensuring the scraping effect.

[0011] The present invention is further configured such that a turntable is fixedly sleeved on the top of the rotating shaft.

[0025] Example 1: refer to Figure 1 , Figure 2 and Figure 3 A glue-applying device for a laminating machine used in the production of honeycomb paperboard includes a fixed frame 1. Two grooves 2 are formed on the inner wall of the fixed frame 1. Sliding blocks 3 are slidably connected to the inner wall of the grooves 2. A fixed seat 4 is bolted between the two sliding blocks 3. A screw 5 is threadedly connected to the inner wall of the sliding blocks 3, and the screw 5 is rotatably connected to the inner wall of the fixed frame 1. A rotating shaft 6 is rotatably sleeved on the inner wall of the fixed frame 1. A first bevel gear 7 is fixedly sleeved at the bottom of the rotating shaft 6. Two bevel gear drive shafts 8 mesh with the surface of the first bevel gear 7, and the bevel gear drive shafts 8 are connected to the fixed frame 1. The inner wall is rotated and sleeved, and the other end of the bevel gear drive shaft 8 is engaged with the second bevel gear 9. The axis of the second bevel gear 9 is fixedly sleeved with the top of the screw 5. By rotating the turntable 21, the rotating shaft 6 drives the first bevel gear 7 to rotate. The rotation of the first bevel gear 7 drives the bevel gear drive rod to drive the second bevel gear 9 to rotate. The rotation of the second bevel gear 9 drives the screw 5 to move the slider 3. The movement of the slider 3 moves the scraper 13. This method can achieve the purpose of easy height adjustment, reduce the workload, and ensure the level of the scraper 13.

[0026] refer to Figure 1 and Figure 3 A turntable 21 is fixedly sleeved on the top of the rotating shaft 6. The turntable 21 facilitates the rotation of the rotating shaft 6.

[0027] refer to Figure 1 The inner wall of the fixing frame 1 is printed with scale lines 24. By setting the scale lines 24, it is easy to adjust the height of the scraper plate 13.

[0028] Example 2: refer to Figure 1 , Figure 2 and Figure 4A mounting base 10 is slidably connected to the inner wall of the fixed base 4. An adjustment mechanism 11 is provided between the inner wall of the mounting base 10 and the fixed base 4. A mounting rod 12 is slidably sleeved on the inner wall of the mounting base 10. A scraper 13 is bolted to the bottom of the mounting rod 12. A pressing rod 14 is slidably sleeved on the inner wall of the mounting base 10. A first spring 15 is provided between one end of the pressing rod 14 and the inner wall of the mounting base 10. A snap-fit ​​connector 16 is bolted to the surface of the pressing rod 14. A snap-fit ​​hole 17 is opened on the surface of the mounting rod 12, and the snap-fit ​​connector 16 snaps into the snap-fit ​​hole 17. By pressing the pressing head 22, the pressing rod 14 drives the snap-fit ​​connector 16 to move. The movement of the snap-fit ​​connector 16 disengages the snap-fit ​​connector 16 from the snap-fit ​​hole 17, allowing the scraper 13 to be removed and replaced. This method facilitates the replacement of the scraper 13, reduces workload, improves replacement efficiency, and is convenient to use.

[0029] refer to Figure 2 The adjustment mechanism 11 includes an adjustment plate 18, which is slidably connected to the inner wall of the fixed base 4. An adjustment bolt 19 is rotatably connected to the top of the adjustment plate 18, and the adjustment bolt 19 is threadedly connected to the inner wall of the fixed base 4. A second spring 20 is fixedly connected between the adjustment plate 18 and the mounting base 10 through a spring fixing member. By setting the adjustment mechanism 11, rotating the adjustment bolt 19 causes the adjustment bolt 19 to drive the adjustment plate 18 to move. The movement of the adjustment plate 18 changes the elastic force of the second spring 20. The change in the elastic force of the second spring 20 changes the pressure between the scraper plate 13 and the honeycomb paperboard, thereby adjusting the pressure of the scraper plate 13 and ensuring the scraping effect.

[0030] refer to Figure 1 and Figure 2 One end of the pressing rod 14 is bolted with a pressing head 22. The pressing head 22 facilitates the movement of the pressing rod 14.

[0031] refer to Figure 4 One end of the snap-fit ​​connector 16 is wedge-shaped, which facilitates the fixing of the scraper plate 13.

[0032] refer to Figure 1 and Figure 2 The adjusting bolt 19 has a threaded connection to a fixing nut 23. By setting the fixing nut 23, the adjusting bolt 19 is fixed, thereby improving stability.

[0033] Brief description of the usage process: The device is installed behind the glue-coating roller of the paper mounting machine, so that the scraper 13 contacts the honeycomb paperboard. During the paper mounting process, the scraper 13 scrapes off the glue on the surface of the honeycomb paperboard. Rotating the turntable 21 causes the rotating shaft 6 to rotate, which in turn causes the first bevel gear 7 to rotate, which in turn causes the bevel gear drive shaft 8 to rotate, which in turn causes the second bevel gear 9 to rotate, which in turn causes the screw 5 to rotate. The rotation of the screw 5 causes the slider 3 to move longitudinally along the slide groove 2. The longitudinal movement of the slider 3 causes the fixed seat 4 to move the mounting seat 10, which in turn causes the scraper 13 to move longitudinally, thereby facilitating the adjustment of the height of the scraper 13. Press the pressing head 22. The pressing head 22 moves, which drives the pressing rod 14 to move. The pressing rod 14 moves, which drives the locking connector 16 to move. The locking connector 16 moves, causing it to disengage from the locking hole 17. Remove the scraper 13 and insert the mounting rod 12 on the new scraper 13 into the mounting base 10. Since one end of the locking connector 16 is wedge-shaped, the pressing rod 14, under the action of the first spring 15, drives the locking connector 16 to engage with the locking hole 17, fixing it in place and completing the replacement. This achieves the purpose of facilitating the replacement of the scraper 13.
