[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention provides a frosting block. After the frosting block slides down, the guide groove at the bottom of the frosting block will abut against the blade of the cutting wheel. During the rotation of the cutting wheel, the cutting wheel can be polished, which can effectively ensure the sharpness of the cutting wheel.

In the process of the air flow flowing through the groove, on the one hand, the air flow will blow the debris generated by cutting between the cutting wheel and the wallpaper into the exhaust groove, and then discharge the debris. On the other hand, the flow of air flow can also dissipate the heat of the cutting wheel, which is beneficial to avoid the cutting quality and efficiency being affected by excessive heat generated by the cutting wheel during the cutting process. Secondly, the heat dissipation of the cutting wheel can also reduce the wear and thermal expansion of the cutting wheel, thereby increasing the service life of the cutting wheel. It should be noted that the cutting wheel will generate high temperature after friction, and when cutting chemical fiber wallpaper, it will sinter the wallpaper, thus affecting the cutting quality and efficiency.

[0027] 3. The present invention provides an oil replenishing assembly. After the gas blown out by the air pump enters the refueling box, it will push the sliding column to move in the direction close to the second gantry, so that the sliding column squeezes the lubricating oil in the refueling box, so that the lubricating oil in the refueling box can enter the horizontal groove through the one-way oil outlet pipe, and then enter the vertical slide groove through the oil leakage hole. After the lubricating oil enters the vertical slide groove, it will be retained in the space between the electric slider and the tool holder. Then, during the movement of the electric slider, the lubricating oil will be applied to the vertical slide groove, so that the vertical slide groove and the electric slider are effectively lubricated.

[0065] As a further embodiment of the present invention, the working method of the length measuring sensor 27 during the wallpaper cutting process is specifically as follows:

[0066] The length measuring sensor 27 obtains the length information of the wallpaper passing thereunder;

[0067] The length measurement sensor 27 generates request information according to the length information;

[0068] The length measuring sensor 27 sends a request message to the controller to request the controller to perform the next action;

[0069] The length measuring sensor 27 is provided with a preset length value. After the length information acquired by the length measuring sensor 27 reaches the preset length value, the length measuring sensor 27 generates request information.

[0070] In a specific implementation, the length measuring sensor 27 is in communication connection with a controller embedded therein.

[0071] Working principle of the present invention:

[0072] When the present invention is used, first, a loading rack is placed at one end of the workbench 1, and wallpaper is pre-set on the loading rack. Then, one end of the wallpaper is passed through the loading roller group 11, the bottom of the cutting wheel 10, the bottom of the cutting knife 26, and the bottom of the limiting roller 12 in sequence, and finally wound on the winding rack. It should be noted that the winding rack is provided with two winding rollers, and the cut wallpaper is alternately wound on the two winding rollers to separate the cut wallpaper. It should be noted that the winding roller can be wound by itself, and a winding motor is provided on one side of the winding roller. The winding motor is used to drive the winding roller to roll up the wallpaper. This technology is a prior art and will not be disclosed in detail here.

[0073] In the process of cutting wallpaper, the cut wallpaper is wound around by the rotation of the winding frame, and the wallpaper is fed by the feeding roller group 11 and rolled up by the winding frame, so that the wallpaper can be effectively cut into multiple separate wallpapers by the cutting wheel 10. During the rotation of the cutting wheel 10, the cutting wheel 10 will effectively cut the wallpaper. During the cutting process, the cutting wheel 10 will produce a certain amount of debris after cutting the wallpaper, and the debris will fall into the groove 29. By turning on the air pump 5 and connecting the output end of the air pump 5 with the heat dissipation air pipe 7 through the electromagnetic three-way valve 6, the gas blown out of the air pump 5 will enter the horizontal air groove 28 through the heat dissipation air pipe 7, and then enter the groove 29 through the horizontal air groove 28. Finally After that, it is discharged through the exhaust groove 30. In the process of the airflow flowing through the groove 29, on the one hand, the airflow will blow the debris generated by cutting between the cutting wheel 10 and the wallpaper into the exhaust groove 30, and then discharge the debris. On the other hand, the flow of airflow can also dissipate heat for the cutting wheel 10, which is beneficial to avoid the excessive heat generated by the cutting wheel 10 during the cutting process and affect the cutting quality and efficiency. Secondly, the heat dissipation of the cutting wheel 10 can also reduce the wear and thermal expansion of the cutting wheel 10, thereby increasing the service life of the cutting wheel 10. It should be noted that the cutting wheel 10 will generate high temperature after friction, and when cutting chemical fiber wallpaper, it will sinter the wallpaper, thus affecting the cutting quality and efficiency.

[0074] During the process of cutting wallpaper, the two baffles 2 will block the top two sides of the cutting wheel 10, which is helpful to prevent the cutting wheel 10 from breaking due to excessive fatigue and then flying away. During the process of the cutting wheel 10 breaking and flying away, the baffles 2 can effectively block the cutting wheel 10, thereby improving the safety of wallpaper cutting, and the frosting block 36 can also block the cutting wheel 10, thereby further improving the safety of the cutting wheel 10.

[0075] When the length measuring sensor 27 detects that the wallpaper has reached a predetermined length, the length measuring sensor 27 will send a request message to the controller. After receiving the request message, the controller generates a first control message and a second control message, and sends them to the electric slider 39 and the feeding roller group 11 respectively. After receiving the second control message, the feeding roller group 11 stops feeding the wallpaper, and the electric slider 39 will slide downward after receiving the first control message from the receiving slot, and drive the cutting knife 26 to descend through the knife holder 13, so that the cutting knife 26 cuts the wallpaper longitudinally. After the cutting is completed, the cut wallpaper is wound around the winding roller on the winding frame, and then packaged.

[0076] As the use time goes by, the cutting wheel 10 will be damaged due to friction. When the cutting wheel 10 is worn, certain burrs will be produced during the subsequent wallpaper cutting process. In severe cases, the wallpaper will be damaged, resulting in cutting failure. When the cutting wheel 10 is worn, the output end of the air pump 5 is connected to the clean air pipe 8 by controlling the electromagnetic three-way valve 6, so that the air pump 5 supplies air to the built-in groove 31 through the clean air pipe 8. In the process of supplying air to the built-in groove 31, the air pressure in the built-in groove 31 will increase, and the air pressure will be used to push the piston plate 34 to slide downward in the piston cylinder 33. In the process of sliding down, the piston plate 34 will drive the sliding plate 35 to slide downward through the piston rod 32, so that the sliding plate 35 drives multiple frosting blocks 36 to slide downward. After the frosting blocks 36 slide down, the guide grooves at the bottom of the frosting blocks 36 will abut against the blades of the cutting wheel 10. In the process of rotating the cutting wheel 10, the cutting wheel 10 can be polished, which can effectively ensure the sharpness of the cutting wheel 10. After the cutting wheel 10 is polished, it is helpful to avoid the occurrence of burrs in the wallpaper during the subsequent cutting process due to the wear of the cutting wheel 10.

[0077] During the descending process of the sliding plate 35, the sliding plate 35 will drive the double-sided rack 40 to slide down, and the double-sided rack 40 will then drive the two gears 4 abutting on both sides to rotate, so that the two gears 4 will respectively drive the single-sided rack 41 to rise, and during the rising process of the single-sided rack 41, it will drive the baffle 2 to rise, and then the baffle 2 will slide up on both sides of the first gantry 3, so that the cutting wheel 10 can be exposed, so that the debris generated by the grinding block 36 on the cutting wheel 10 can be effectively discharged.

[0078] When the air pressure in the built-in groove 31 increases to the preset pressure value of the air pressure valve, the air pressure valve opens. After the air pressure valve opens, gas will be transported into the air intake pipe 25. After entering the air intake pipe 25, the gas will enter the three-way interface 24, and then enter the pressure relief pipe 23 or the drive pipe 22 through the three-way interface 24. When there is no need to drive the oil replenishing component, the solenoid valve at the bottom of the pressure relief pipe 23 is opened to allow the air flow to be discharged through the pressure relief pipe 23.

[0079] During the process of driving the oil replenishing assembly, the solenoid valve at the bottom of the pressure relief pipe 23 is closed, so that the gas enters the refueling box 16 through the driving pipe 22. After the gas enters the refueling box 16, it pushes the sliding column 21 to move toward the direction close to the second gantry 14, so that the sliding column 21 squeezes the lubricating oil in the refueling box 16, so that the lubricating oil in the refueling box 16 can enter the horizontal groove 19 through the one-way oil outlet pipe 18, and then enter the vertical slide groove 38 through the oil leakage hole 37. After the lubricating oil enters the vertical slide groove 38, it will stay in the space between the electric slider 39 and the tool holder 13. Then, during the movement of the electric slider 39, the lubricating oil is applied to the vertical slide groove 38, and effective lubrication is performed between the vertical slide groove 38 and the electric slider 39. Since the lubricating oil has a certain viscosity, part of the lubricating oil will be retained in the transverse groove 19. During the sliding of the electric slider 39, the vibration generated by the sliding of the electric slider 39 will be transmitted to the second gantry 14. Then, the vibration can be used to shake out the lubricating oil retained in the transverse groove 19, and the electric slider 39 and the vertical slide groove 38 will be further lubricated.

[0080] After the oil filling work is completed, the solenoid valve is opened, so that the sliding cylinder 21 rebounds under the action of the spring 20. During the rebound of the sliding cylinder 21, the oil filling box 16 extracts lubricating oil from the oil tank 15 through the one-way oil inlet pipe 17 for temporary storage. Through the setting of the air hole, after the sliding cylinder 21 squeezes the spring 20, the sliding cylinder 21 gradually moves to the side of the air hole close to the second gantry 14, and then a passage is formed between the driving pipe 22, the chamber in the oil filling box 16 located on the side of the sliding cylinder 21 away from the second gantry 14, and the air hole, so that the air flow can be discharged through the air hole. On the one hand, it can be judged whether the refueling is completed by using whether there is air flow passing through the bottom of the air hole. On the other hand, the exhaust of the air hole can also avoid excessive air pressure in the built-in groove 31 due to the inability to discharge air, thereby causing the grinding block 36 to exert excessive pressure on the cutting wheel 10.
