[0001] The invention relates to the technical field of milling, in particular to a milling device for producing nano and polyurethane paint rollers. Background Art

[0002] The paint roller milling device forms uniform micron or nanometer texture on the surface of the paint roller through precision milling process to enhance the adhesion and uniformity of the coating. The device is usually equipped with an advanced numerical control system (CNC) to ensure high automation and precise control of the processing process. It is suitable for the production of high-quality polyurethane paint rollers and is widely used in surface treatment processes in the automotive, furniture, electronic products and other industries.

[0003] During the production of paint rollers, the milling process will produce long strips of chips. If these chips are not handled in time, they will easily accumulate and adhere to the vicinity of the milling cutter. Since the milling cutter will overheat during operation, this will cause the chips to melt and further adhere to the paint roller, causing adhesion problems, leading to frequent cleaning difficulties during the processing process, affecting production efficiency and product quality.

[0004] Based on the above situation, the present invention proposes a milling device for producing nano and polyurethane paint rollers. Summary of the invention

[0007] As an improvement of the above solution, at least one milling cutter is fixedly connected to the tool holder disc by bolts.

[0008] As an improvement of the above solution, the guide plate is provided with a movable groove, and the guide plate is movably connected to the turning handle via the movable groove.

[0009] As an improvement of the above solution, the guide grooves of the guide plate are distributed in an inverted figure eight shape.

[0010] As an improvement of the above scheme, it also includes a pressure frame, which is slidably connected to the electric turntable, the pressure frame is provided with inclined surfaces symmetrically distributed along the pressure frame, the connecting frame is slidably connected to a guide frame, the guide frame is fixedly connected to the connecting frame, the guide frame has an inclined groove, the guide frame is slidably connected to the pressure frame via the inclined groove, a tension spring is fixedly connected between the guide frame and the electric turntable, the tool holder disc is fixedly connected with pressure rods evenly distributed in the circumference, and the pressure rods rotate to be extruded and matched with the inclined surfaces of the pressure frame.

[0011] As an improvement of the above scheme, it also includes a roller, which is rotatably connected to a side of the suction frame close to the inlet, and a rotating frame is rotatably connected to a side of the suction frame close to the outlet, a fixed plate is fixedly connected to a side of the suction frame close to the rotating frame, and a pulley assembly is connected between the roller and the rotating frame.

[0012] As an improvement of the above solution, a plurality of short rods are arranged on the roller to effectively capture and comb the chips cut off by the milling cutter.

[0013] As an improvement of the above scheme, it also includes at least one scraper, which is fixed to one side of the suction frame close to the roller. The scraper is provided with short grooves distributed at equal intervals, and the short grooves are used for the short rod of the roller to pass through when it rotates.

[0014] As an improvement of the above scheme, it also includes an installation frame, which is slidably connected to the suction frame, and the installation frame is rotatably connected to a material guide plate symmetrically distributed along the installation frame, and the suction frame is fixed with a guide block symmetrically distributed along the material guide plate, and the guide block is set as a wedge-shaped surface, and the guide block is squeezed and matched with the adjacent material guide plate through the wedge-shaped surface, and a torsion spring is fixed between the material guide plate and the installation frame.

[0018] The present invention uses a suction fan to assist the roller to straighten the long strip of scraps, and assists the long strip of scraps to be smoothly sucked into the suction rack, preventing the scraps from being entangled on the roller, thereby avoiding the work influence of the roller and preventing the scraps from being accumulated at the entrance of the suction rack.

DETAILED DESCRIPTION

[0032] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0033] Example 1: A milling device for producing nano and polyurethane paint rollers, such as Figure 1-Figure 4 As shown, it includes a milling bed 1, the upper part of the milling bed 1 is rotatably connected to a paint roller 101, the middle of the milling bed 1 is slidably connected to an axle frame 2 in the left-right direction, the top of the axle frame 2 is slidably connected to an electric turntable 201 in the front-back direction, the electric turntable 201 is rotatably connected to a tool holder disc 3, three milling cutters can be fixedly connected to the tool holder disc 3 by bolts, the electric turntable 201 is slidably connected to a connecting frame 4 in the left-right direction, the top of the connecting frame 4 is fixedly connected to a suction frame 5, the lower rear part of the suction frame 5 is connected to a suction fan pipe 6, the front side of the suction frame 5 is fixedly connected to a motor 7, the output shaft of the motor 7 is fixedly connected to a rotating handle 8, the front side of the suction frame 5 is connected to the upper A guide plate 9 is slidably connected to the lower direction, a movable groove is opened on the lower side of the guide plate 9, the guide plate 9 is movably connected to the rotating handle 8 through the movable groove, and a guide groove symmetrically distributed along the guide plate 9 is opened on the upper side of the guide plate 9, and the two guide grooves of the guide plate 9 are distributed in an inverted eight-shaped shape. A cutting frame 10 is fixedly connected to the upper inner part of the suction frame 5, and a cutter 11 symmetrically distributed along the cutting frame 10 is slidably connected in the middle of the cutting frame 10, and the front side of the cutter 11 is slidably connected to the guide groove adjacent to the guide plate 9. When the left and right cutters 11 are close to each other, they cooperate with each other to form a pair of scissors in the middle, and when the left and right cutters 11 are away from each other, they cooperate with the cutting frame 10 to form scissors on both sides.

[0034] When the milling bed 1 starts working, it first drives the electric turntable 201 to slide backward, so that the tool holder disc 3 drives the milling cutter to move backward until it contacts the surface of the paint roller 101, and then drives the shaft frame 2 to move from left to right, thereby driving the electric turntable 201, the tool holder disc 3, the connecting frame 4, the suction frame 5, the suction fan pipe 6, the motor 7, the rotating handle 8, the guide plate 9, the cutting frame 10 and the cutting cutter 11 to move slowly from left to right as a whole. In this process, the milling cutter cuts out long strips of chips on the paint roller 101. At the same time, under the action of the suction force of the suction fan, the chips are sucked into the suction frame 5. The output shaft of the motor 7 intermittently rotates forward and reversely to drive the rotating handle 8 to rotate forward and reverse, thereby driving the guide plate 9 Intermittent up and down sliding, when the guide plate 9 slides downward, the guide plate 9 pushes the two cutters 11 to slide along the cutting frame 10 in the direction away from each other through the guide groove. At this time, each cutter 11 cooperates with the left and right sides of the cutting frame 10 respectively to form a "left shear" and a "right shear". When the guide plate 9 slides upward, the guide plate 9 pushes the two cutters 11 to slide along the cutting frame 10 in the direction close to each other through the guide groove. At this time, the two cutters 11 cooperate with each other to form a "middle shear". In this way, the scraps sucked into the suction frame 5 can be shredded in a fancy way regardless of whether they float to the left, right or middle part, and the shredded scraps are sucked into the suction fan along the suction frame 5 for collection.

[0035] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 and Figure 5 As shown, it also includes a pressure frame 12, which is slidably connected to the electric turntable 201. The right part of the pressure frame 12 is provided with inclined surfaces symmetrically distributed along the left and right directions of the pressure frame 12. The left part of the connecting frame 4 is slidably connected with a guide frame 13 along the left and right directions. The lower part of the guide frame 13 is fixedly connected to the left side of the connecting frame 4. The upper part of the guide frame 13 is provided with an inclined groove. The guide frame 13 is slidably connected to the pressure frame 12 through the inclined groove. A tension spring 14 is fixedly connected between the guide frame 13 and the electric turntable 201. The lower part of the tool holder disc 3 is fixedly connected with three pressure rods 15 evenly distributed along the circumferential direction. The pressure rods 15 rotate to squeeze and fit with the inclined surface of the pressure frame 12, so that the pressure frame 12 slides downward.

[0036] Three milling cutters are fixed on the tool holder disc 3. When the cutter needs to be changed, the tool holder disc 3 needs to be controlled to rotate. When the tool holder disc 3 drives the milling cutter to rotate, the suction rack 5 will block the position. Therefore, the following specific operations need to be performed to achieve the avoidance of the suction rack 5: No matter the tool holder disc 3 rotates forward or reversely, the tool holder disc 3 will drive one of the pressure rods 15 to rotate until it contacts the inclined surface on one side of the pressure frame 12. The pressure rod 15 rotates to squeeze the inclined surface, causing the pressure frame 12 to slide downward. The pressure frame 12 moves to the right by squeezing the guide frame 13 through the inclined groove, thereby driving the connecting frame 4 to slide to the right relative to the electric turntable 201. The tension spring 14 is stretched, and the connecting frame 4 drives the suction frame 5 to move to the right, increasing the distance between the tool holder disc 3 and the suction frame 5, so that when the milling cutter is changed, the suction frame 5 can avoid the milling cutter.

[0037] When the pressing rod 15 rotates to disengage from the inclined surface of the pressing frame 12, the tension spring 14 resets and drives the connecting frame 4 to slide leftward relative to the electric turntable 201, and the connecting frame 4 drives the guide frame 13 and the suction frame 5 to move leftward, and the guide frame 13 pushes the pressing frame 12 to slide upward and reset through the inclined groove.

[0038] Embodiment 3: Based on embodiment 2, Figure 6 As shown, it also includes a roller 16, which is rotatably connected to the side of the suction frame 5 near the entrance. A plurality of short rods are arranged on the roller 16 for effectively capturing and combing the chips cut by the milling cutter. A rotating frame 18 is rotatably connected to the side of the suction frame 5 near the exit. A fixing plate 17 is fixedly connected to the side of the suction frame 5 near the rotating frame 18. A pulley assembly 19 is connected between the roller 16 and the rotating frame 18.

[0039] Under the action of the suction force of the suction fan, the outside air enters the suction rack 5 through the inlet, the wind force drives the rotating rack 18 to rotate, and the rotating rack 18 drives the roller 16 to rotate through the pulley assembly 19, thereby straightening the long strip chips and assisting the long strip chips to be smoothly sucked into the suction rack 5.

[0040] like Figure 7 As shown, two scrapers 20 are also included. The scraper 20 is fixed to one side of the suction frame 5 close to the roller 16. The lower side of the scraper 20 is provided with short grooves distributed at equal intervals. The short grooves are used for the short rods of the roller 16 to pass through when rotating, so as to prevent the long strips of scraps from being entangled between the short rods of the roller 16.

[0041] Embodiment 4: Based on embodiment 3, Figure 8-Figure 10 As shown, it also includes a mounting frame 211, which is slidably connected to the suction frame 5, and the mounting frame 211 is rotatably connected to a material guide plate 21 that is symmetrically distributed along the mounting frame 211, and the suction frame 5 is fixedly connected to a guide block 22 that is symmetrically distributed along the material guide plate 21, and the upper side surface of the upper guide block 22 and the lower side surface of the lower guide block 22 are both set as wedge-shaped surfaces, and the guide block 22 is squeezed and matched with the adjacent material guide plate 21 through the wedge-shaped surface, and a torsion spring 23 is fixed between the material guide plate 21 and the mounting frame 211.

[0042] By pushing the installation frame 211 forward, the installation frame 211 drives the guide plate 21 to move forward, and under the squeezing effect of the wedge-shaped surface of the guide block 22, the guide plate 21 rotates outward to open. The longer the forward push distance is, the larger the opening of the two guide plates 21 is. When the forward thrust is gradually removed from the installation frame 211, the torsion spring 23 is gradually reset, thereby driving the guide plate 9 to rotate inward. The greater the unloading force is, the smaller the opening of the two guide plates 21 is, thereby achieving the effect of adjusting the opening size of the suction inlet. In this way, the opening can be reduced when a larger suction force is needed, and the opening can be increased when there are more scraps.

[0043] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
