Description

Technical Field

[0001] This utility model relates to the field of scraping device technology, and in particular to a scraping device for a scraping wheel. Background Technology

[0002] In a corrugated cardboard production line, the gluer removes excess glue from the glue roller by setting the gap between the glue roller and the linerboard. Then, a scraper removes the glue from the glue roller. During operation, the position of the glue roller must be adjusted to regulate the gap between the glue roller and the linerboard, precisely controlling the amount of glue on the glue roller to ensure that the appropriate amount of glue is applied and transferred to the different types of single-faced corrugated paper. This allows the single-faced corrugated paper to bond with the linerboard, forming the corrugated cardboard used for cartons on the market.

[0003] In existing scraping devices, the scraper blade directly presses against the scraper roller, and the scraper roller itself rotates to scrape off the paste. During operation, the scraper blade cannot move with the scraper roller. When the scraper blade wears down, a gap will appear between the scraper blade and the scraper roller, making it impossible to completely remove the paste from the scraper roller. In addition, when the paste is not scraped cleanly, it is often necessary to tighten the scraper blade to ensure that it is in contact with the scraper roller. However, excessive pressure can cause the scraper roller to deform, affecting the size of the gap between the scraper roller and the scraper roller in certain areas. This results in inaccurate control of the paste amount, leading to defects in the corrugated cardboard produced, such as bubbling, insufficient stiffness, and excessive paste application, which greatly reduces the production efficiency and quality of the corrugated cardboard production line. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a scraping device for scraping rollers that can ensure that the scraper blade and the scraper roller abut against each other without excessively squeezing the scraper roller.

[0005] To solve the above-mentioned technical problems, this utility model provides a scraping device for a scraping roller, comprising:

[0006] A support shaft is provided along the axial direction of the scraper wheel and is located on one side of the scraper wheel;

[0007] A swing assembly is mounted on the support shaft. The swing assembly includes a rotating seat, a bottom plate, a top plate, and an elastic component. The rotating seat is rotatably connected to the support shaft. The bottom plate is fixed on the side of the rotating seat away from the scraper wheel. The top plate is fixed on the support shaft and located above the bottom plate. The elastic component is clamped by the top plate and the bottom plate to produce elastic deformation and has a compression margin.

[0008] A scraper blade is fixed to the bottom of the rotating base, and the top of the scraper blade near the scraper wheel abuts against the bottom of the scraper wheel.

[0009] As a preferred embodiment of this utility model, the elastic component includes a connecting bolt, a connecting nut, and a spring. The top plate has a mounting hole at its top, and the bottom plate has a mounting slot at its bottom. The connecting bolt passes through the mounting hole and the mounting slot, and the connecting bolt is slidably engaged with the mounting hole. The connecting bolt can swing relative to the mounting slot. The connecting nut is threadedly connected to the connecting bolt, and the top of the connecting nut abuts against the bottom of the bottom plate. The spring is sleeved on the connecting bolt and located between the top plate and the bottom plate. The spring is in a compressed state and has a compression allowance.

[0010] As a preferred embodiment of this utility model, it further includes an adjusting nut that is threadedly connected to the connecting bolt, the adjusting nut being located between the top plate and the bottom plate, and the spring being located between the adjusting nut and the bottom plate.

[0011] As a preferred embodiment of this utility model, the device further includes a fixing base, the top of which is provided with a mounting groove, the end of the support shaft is disposed in the mounting groove, and the two sides of the end of the support shaft are respectively provided with positioning planes that fit and connect with the sidewalls of the mounting groove.

[0012] As a preferred embodiment of this utility model, a locking through hole is provided on one side of the mounting groove, and a locking bolt is threaded into the locking through hole, with the end of the locking bolt abutting against the positioning plane.

[0013] As a preferred embodiment of this utility model, a mounting plate is fixed to the bottom of the rotating seat, and a detachable clamping plate is provided below the mounting plate. The side of the scraper away from the scraper wheel is fixed between the mounting plate and the clamping plate.

[0014] As a preferred embodiment of the present invention, the swing assembly is provided in multiple parts and arranged at intervals along the axial direction of the support shaft.

[0015] As a preferred embodiment of this utility model, the top plate is provided with a clearance groove, and the top of the rotating seat is located in the clearance groove.

[0016] This utility model provides a scraping device for a scraping wheel. Compared with the prior art, its advantages are as follows: Since the scraper plate, rotating seat, and bottom plate are fixedly connected as one unit, and the top plate is fixedly connected to the support shaft, when the scraping wheel is adjusted downwards, the scraper plate will rotate downwards, and the bottom plate will rotate upwards. This causes the elastic component to be compressed and undergo elastic deformation, thereby preventing excessive force between the scraper plate and the scraping wheel from causing deformation of the scraping wheel. Since the elastic component is compressed and undergoes elastic deformation, when the scraping wheel is adjusted upwards, under the elastic force of the elastic component, the bottom plate rotates downwards, and the scraper plate rotates upwards, thereby ensuring that the scraper plate and the scraping wheel remain in contact. That is, this device can ensure that the scraper plate and the scraping wheel are in contact without excessively squeezing the scraping wheel. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] like Figure 1-4 As shown, a preferred embodiment of the present invention provides a scraping device for a scraping roller 7, comprising:

[0025] Support shaft 1 is arranged along the axial direction of scraper 7 and located on one side of scraper 7. Generally, support shaft 1 is installed and fixed on the frame wall of the glue machine and located on the side of scraper 7 away from the glue wheel.

[0026] The swing assembly 2 is mounted on the support shaft 1. The swing assembly 2 includes a rotating seat 21, a bottom plate 22, a top plate 23, and an elastic component 24. The rotating seat 21 is rotatably connected to the support shaft 1. In this embodiment, the rotating seat 21 is provided with a through hole that rotatably engages with the support shaft 1, that is, the rotating seat 21 can be rotatably sleeved on the support shaft 1. The bottom plate 22 is fixed on the side of the rotating seat 21 away from the scraper wheel 7. The top plate 23 is fixed on the support shaft 1 and located above the bottom plate 22. The elastic component 24 is clamped by the top plate 23 and the bottom plate 22 to produce elastic deformation and has a compression margin. That is, when the bottom plate 22 rotates upward, the elastic component 24 can still be compressed within the range of elastic deformation.

[0027] The scraper 3 is fixed to the bottom of the rotating seat 21, and the top of the scraper 3 near the scraper wheel 7 abuts against the bottom of the scraper wheel 7.

[0028] The working principle of this embodiment is as follows: Under normal conditions, the scraper plate 3 abuts against the bottom of the scraper wheel 7, allowing the scraper plate 3 to scrape off the paste on the scraper wheel 7. Since the scraper plate 3, the rotating seat 21, and the bottom plate 22 are fixedly connected as one unit, and the top plate 23 is fixedly connected to the support shaft 1, and the top plate 23 is between the bottom plate 22 and the bottom plate 23, when the scraper wheel 7 is adjusted downwards, the scraper plate 3 will rotate downwards. At this time, the bottom plate 22 will rotate upwards, causing the elastic component 24 to be compressed and undergo elastic deformation, thereby preventing... Excessive force between the scraper blade 3 and the scraper wheel 7 causes deformation of the scraper wheel 7. Due to the elastic deformation caused by the compression of the elastic component 24, when the scraper wheel 7 is adjusted upward, the base plate 22 rotates downward under the elastic force of the elastic component 24, and the scraper blade 3 rotates upward, thereby ensuring that the scraper blade 3 and the scraper wheel 7 remain in contact (within the range of deformation of the elastic component 24 under pressure). That is, this device can ensure that the scraper blade 3 and the scraper wheel 7 are in contact without excessively squeezing the scraper wheel 7.

[0029] For example, the elastic component 24 includes a connecting bolt 241, a connecting nut 242, and a spring 243. The top plate 23 has a mounting hole 231 at its top, and the bottom plate 22 has a mounting slot 221 at its bottom. The connecting bolt 241 passes through the mounting hole 231 and the mounting slot 221, and is slidably engaged with the mounting hole 231. The connecting bolt 241 can swing relative to the mounting slot 221. Specifically, the connecting bolt 241 can rotate upwards and downwards relative to the rotating seat 21 within the mounting slot 221 around the axis of the support shaft 1, meaning the connecting bolt 241 will not interfere with the bottom plate 22, ensuring that the bottom plate 22 can rotate. The connecting nut 242 is screwed onto the connecting bolt 241. The connecting nut 242 abuts against the bottom of the base plate 22. The spring 243 is sleeved on the connecting bolt 241 and located between the top plate 23 and the base plate 22. The spring 243 is in a compressed state with a compression margin. The connecting nut 242 restricts the base plate 22 from moving downward relative to the connecting bolt 241, so that the spring 243 remains in a compressed state. When the base plate 22 rotates upward, the connecting bolt 241 and the top plate 23 remain stationary, and the spring 243 is compressed under the action of the top plate 23 and the base plate 22. When the base plate 22 rotates downward, the top plate 23 remains stationary, the spring 243 extends, and the base plate 22 drives the connecting nut 242 and the connecting bolt 241 to slide downward relative to the top plate 23.

[0030] For example, the device also includes an adjusting nut 244 threadedly connected to the connecting bolt 241. The adjusting nut 244 is located between the top plate 23 and the bottom plate 22, and the spring 243 is located between the adjusting nut 244 and the bottom plate 22. Rotating the adjusting nut 244 can adjust the pressure of the adjusting nut 244 on the spring 243, so that the spring 243 is in a compressed state. During assembly, the compression of the spring 243 can be adjusted by adjusting the adjusting nut 244, thereby adjusting the position of the bottom plate 22 so that the scraper plate abuts against the scraper roller 7.

[0031] For example, the device also includes a fixing seat 4, the top of which is provided with a mounting groove 41. The end of the support shaft 1 is located in the mounting groove 41. It can be understood that the end of the mounting groove 41 near the support shaft 1 is open to ensure that the end of the support shaft 1 can be put into the mounting groove 41. The fixing seat 4 is installed on the frame wall of the scraper, and then the end of the support shaft 1 is installed in the mounting groove 41 to fix the support shaft 1. The assembly and disassembly are simple. The two sides of the end of the support shaft 1 are respectively provided with positioning planes 11 that fit and connect with the side wall of the mounting groove 41 to prevent the support shaft 1 from rotating.

[0032] For example, a locking through hole 42 is provided on one side of the mounting groove 41, and a locking bolt (not shown in the figure) is threaded into the locking through hole 42. The end of the locking bolt abuts against the positioning plane 11 to prevent the end of the support shaft 1 from disengaging from the mounting groove 41.

[0033] For example, the bottom of the rotating seat 21 is fixed with a mounting plate 5, and a detachable clamping plate 6 is provided below the mounting plate 5. The side of the scraper 3 away from the scraper wheel 7 is fixed between the mounting plate 5 and the clamping plate 6. In this embodiment, the mounting plate 5, the scraper 3 and the clamping plate 6 are connected by bolts, that is, the bolts pass through the clamping plate 6 and the scraper and are threadedly connected to the mounting plate 5 so as to facilitate the assembly and disassembly of the scraper 3 and the clamping plate 6.

[0034] For example, multiple swing components 2 are provided and arranged at intervals along the axial direction of the support shaft 1, and the scraper 3 is fixed to the bottom of the rotating seat 21 of the multiple swing components 2 to ensure the stability of the scraper 3 installation.

[0035] For example, the top plate 23 is provided with a relief groove 232, and the top of the rotating seat 21 is located in the relief groove 232 so that the top plate 23 supports the fixed connection of the shaft 1.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
