Description

Technical Field

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

[0002] The paint roller milling device forms uniform micron or nano-scale textures on the surface of the paint roller through precision milling technology to enhance the adhesion and uniformity of the coating. This device is usually equipped with an advanced numerical control system (CNC) to ensure a high degree of 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 industries such as automobiles, furniture, and electronic products.

[0003] During the production process of the paint roller, the milling process will generate long strip-shaped chips. If these chips are not processed in time, they are likely to accumulate and adhere near 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, resulting in adhesion problems, leading to frequent cleaning problems during the processing process and affecting production efficiency and product quality.

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

[0005] In order to overcome the drawback that long chips are likely to accumulate and adhere near the milling cutter if not processed in time and heat up and melt and adhere to the paint roller, the present invention provides a milling device for the production of nano and polyurethane paint rollers.

[0006] A milling device for the production of nano and polyurethane paint rollers includes a milling bed body. The milling bed body is rotatably connected with the paint roller. The milling bed body is slidably connected with an axle frame. The axle frame is slidably connected with an electric turntable. The electric turntable is rotatably connected with a tool holder disc. The electric turntable is slidably connected with a connecting frame. The connecting frame is fixedly connected with a suction frame. The suction frame is communicated with a suction fan pipe. The suction frame is fixedly connected with a motor. The output shaft of the motor is fixedly connected with a rotating handle. The suction frame is slidably connected with a guide plate. The guide plate is movably connected with the rotating handle. The guide plate is provided with guide grooves symmetrically distributed along the guide plate. A cutting frame is fixedly connected inside the suction frame. The cutting frame is slidably connected with cutting knives symmetrically distributed along the cutting frame. The cutting knives are slidably connected with the adjacent guide grooves of the guide plate. When the symmetrically distributed cutting knives approach each other, they cooperate with each other to form scissors in the middle. When the cutting knives move away from each other, they cooperate with the cutting frame to form scissors on both sides.

[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 to the above solution, the guide plate is provided with a movable slot, and the guide plate is movably connected to the rotating handle through the movable slot.

[0009] As an improvement to the above solution, the guide slots of the guide plate are distributed in an inverted V shape.

[0010] As an improvement to the above solution, it further includes a pressing frame. The pressing frame is slidably connected to the electric turntable. The pressing frame is provided with inclined surfaces symmetrically distributed along the pressing frame. A guide frame is slidably connected to the connecting frame. The guide frame is fixedly connected to the connecting frame. The guide frame is provided with an inclined slot. The guide frame is slidably connected to the pressing frame through the inclined slot. A tension spring is fixedly connected between the guide frame and the electric turntable. The tool rest disc is fixedly connected with pressing rods evenly distributed circumferentially. The pressing rods rotate and are in extrusion cooperation with the inclined surfaces of the pressing frame.

[0011] As an improvement to the above solution, it further includes a roller. The roller is rotatably connected to one side of the material suction frame near the inlet. A rotating frame is rotatably connected to one side of the material suction frame near the outlet. A fixed plate is fixedly connected to one side of the material suction frame near the rotating frame. A pulley assembly is connected between the roller and the rotating frame.

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

[0013] As an improvement to the above solution, it further includes at least one scraping plate. The scraping plate is fixedly connected to one side of the material suction frame near the roller. The scraping plate is provided with short slots distributed at equal intervals. The short slots are for the short rods of the roller to pass through when rotating.

[0014] As an improvement to the above solution, it further includes a mounting frame. The mounting frame is slidably connected to the material suction frame. Guide plates symmetrically distributed along the mounting frame are rotatably connected to the mounting frame. Guide blocks symmetrically distributed along the guide plates are fixedly connected to the material suction frame. The guide blocks are provided with wedge-shaped surfaces. The guide blocks are in extrusion cooperation with the adjacent guide plates through the wedge-shaped surfaces. A torsion spring is fixedly connected between the guide plates and the mounting frame.

[0015] The beneficial effects of the present invention are as follows: The present invention instantaneously sucks the cut long strip-shaped chips into the material suction frame through the suction force generated by the suction fan, preventing the chip strips from accumulating near the milling cutter, reducing the risk of chip strip melting caused by overheating, effectively solving the adhesion problem caused by chip strip accumulation, avoiding the chip strips from melting and further adhering to the paint roller, ensuring the smooth progress of the processing process, and improving the product quality.

[0016] The present invention controls the relative movement between two cutting blades by the up-and-down sliding of a guide plate, constituting a fancy shearing machine, achieving multiple shearing and crushing modes such as "left shearing", "right shearing" and "middle shearing", ensuring that the scrap materials can be thoroughly crushed no matter where they float, further improving the efficiency of scrap material collection and reducing the risk of blockage. At the same time, it reduces the downtime caused by cleaning the scrap strips, significantly improving the production efficiency.

[0017] When the milling cutter needs to be replaced in the present invention, the rotation of the tool holder disc will trigger the interaction between the pressure rod and the pressure frame, causing the suction rack to automatically move to the right to avoid the milling cutter, achieving the effect of automatic tool change avoidance, simplifying the tool change process and eliminating the need for manual intervention.

[0018] The present invention uses a suction fan to assist the roller in straightening the long strip-shaped scrap materials, facilitating the smooth suction of the long strip-shaped scrap materials into the suction rack, preventing the scrap materials from winding around the roller, avoiding both the influence on the roller's operation and the accumulation of scrap materials at the entrance of the suction rack.

[0019] The present invention adjusts the angle of the material guide plate by pushing the installation frame, and can flexibly and dynamically adjust the opening size of the suction inlet according to actual needs, so as to adapt to the scrap material processing requirements of different magnitudes, improving the flexibility and applicability of the system.

[0020] The present invention integrates multiple functions such as milling, scrap material collection and processing, reducing the space occupied by the equipment and improving the rationality of the overall layout of the workshop. Description of the Drawings

Specific embodiments

[0032] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0033] Embodiment 1: A milling device for producing nano and polyurethane paint rollers, as Figures 1 - 4 shown, includes a milling machine body 1. A paint roller 101 is rotatably connected to the upper part of the milling machine body 1. A shaft rack 2 is slidably connected to the middle of the milling machine body 1 in the left-right direction. An electric turntable 201 is slidably connected to the top of the shaft rack 2 in the front-rear direction. A tool holder disk 3 is rotatably connected to the electric turntable 201. Three milling cutters can be fixedly connected to the tool holder disk 3 through bolts. The electric turntable 201 is slidably connected to a connecting rack 4 in the left-right direction. A material suction rack 5 is fixedly connected to the top of the connecting rack 4. A suction fan pipe 6 is communicated with the lower part at the rear side of the material suction rack 5. A motor 7 is fixedly connected to the front side of the material suction rack 5. An output shaft of the motor 7 is fixedly connected to a rotating handle 8. A guide plate 9 is slidably connected to the front side of the material suction rack 5 in the up-down direction. An activity 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 activity groove. Guide grooves symmetrically distributed along the left and right of the guide plate 9 are opened on the upper side of the guide plate 9. The two guide grooves of the guide plate 9 are distributed in an inverted V shape. A cutting rack 10 is fixedly connected to the upper part inside the material suction rack 5. Cutting tools 11 symmetrically distributed along the left and right of the cutting rack 10 are slidably connected to the middle of the cutting rack 10. The front sides of the cutting tools 11 are slidably connected to the adjacent guide grooves of the guide plate 9. When the two cutting tools 11 on the left and right approach each other, they cooperate to form scissors in the middle. When the two cutting tools 11 on the left and right move away from each other, they cooperate with the cutting rack 10 to form scissors on both sides.

[0034] When the milling machine body 1 starts to work, first drive the electric turntable 201 to slide backward, so that the tool rest disc 3 drives the milling cutter to move backward until it contacts the surface of the paint roller 101. Then drive the shaft frame 2 to move from left to right, thereby driving the electric turntable 201, the tool rest disc 3, the connecting frame 4, the material 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 tool 11 to slowly move from left to right as a whole. During this process, the milling cutter cuts out strip-shaped chips on the paint roller 101. At the same time, under the action of the suction of the suction fan, the chips are sucked into the material suction frame 5. The output shaft of the motor 7 rotates intermittently forward and backward to drive the rotating handle 8 to rotate forward and backward, thereby driving the guide plate 9 to slide up and down intermittently. When the guide plate 9 slides downward, the guide plate 9 pushes the two cutting tools 11 along the cutting frame 10 to slide in the direction away from each other through the guide groove. At this time, each cutting tool 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 cutting tools 11 along the cutting frame 10 to slide in the direction close to each other through the guide groove. At this time, the two cutting tools 11 cooperate with each other to form a "middle shear". In this way, no matter whether the chips sucked into the material suction frame 5 float to the left, right or middle, they can be cut into fancy shapes. The cut chips are sucked into the suction fan along the material suction frame 5 for collection.

[0035] Embodiment 2: On the basis of Embodiment 1, as Figure 1 , Figure 2 and Figure 5 shown, it further includes a pressing frame 12. The pressing frame 12 is slidably connected to the electric turntable 201. The right part of the pressing frame 12 is provided with inclined surfaces symmetrically distributed along the left and right of the pressing frame 12. The left part of the connecting frame 4 is slidably connected with a guide frame 13 in the left-right direction. 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 with the pressing frame 12 through the inclined groove. A tension spring 14 is fixedly connected between the guide frame 13 and the electric turntable 201. Three pressing rods 15 evenly distributed along the circumferential direction are fixedly connected to the lower part of the tool rest disc 3. The pressing rods 15 rotate and are in extrusion cooperation with the inclined surfaces of the pressing frame 12, so that the pressing frame 12 slides downward.

[0036] When three milling cutters are fixed on the tool rest disc 3, when a tool change is required, it is necessary to control the rotation of the tool rest disc 3. When the tool rest disc 3 drives the milling cutter to rotate, the material suction frame 5 will be blocked. Therefore, the following specific operations are required to achieve the avoidance of the material suction frame 5:

[0037] Regardless of whether the tool rest disc 3 rotates forward or backward, the tool rest 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 and squeezes the inclined surface, causing the pressure frame 12 to slide downward. The pressure frame 12 squeezes the guide frame 13 through the inclined groove to move it to the right, 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 material suction frame 5 to move to the right, increasing the distance between the tool rest disc 3 and the material suction frame 5. When the milling cutter changes tools, the material suction frame 5 can avoid the milling cutter.

[0038] When the pressure rod 15 rotates until it disengages from the inclined surface of the pressure frame 12, the tension spring 14 resets and drives the connecting frame 4 to slide to the left relative to the electric turntable 201. The connecting frame 4 drives the guide frame 13 and the material suction frame 5 to move to the left, and the guide frame 13 pushes the pressure frame 12 to slide upward and reset through the inclined groove.

[0039] Example 3: On the basis of Example 2, as Figure 6 shown, it further includes a roller 16. The roller 16 is rotatably connected to one side of the material suction frame 5 near the entrance. A plurality of short rods are provided on the roller 16 for effectively capturing and combing the chips cut by the milling cutter. A rotating frame 18 is rotatably connected to one side of the material suction frame 5 near the exit. A fixing plate 17 is fixedly connected to one side of the material suction frame 5 near the rotating frame 18. A pulley assembly 19 is connected between the roller 16 and the rotating frame 18.

[0040] Under the action of the suction force of the suction fan, the outside air enters the material suction frame 5 through the entrance. The wind force drives the rotating frame 18 to rotate. The rotating frame 18 drives the roller 16 to rotate through the pulley assembly 19, thereby straightening the long strip-shaped chips and assisting the long strip-shaped chips to be smoothly sucked into the material suction frame 5.

[0041] As Figure 7 shown, it further includes two scraping plates 20. The scraping plates 20 are fixedly connected to one side of the material suction frame 5 near the roller 16. Short grooves are provided at equal intervals on the lower side of the scraping plates 20 for the short rods of the roller 16 to pass through when rotating, preventing the long strip-shaped chips from winding between the short rods of the roller 16.

[0042] Example 4: On the basis of Example 3, as Figures 8 - 10 shown, it further includes a mounting frame 211. The mounting frame 211 is slidably connected to the material suction frame 5. Guide plates 21 are rotatably connected to the mounting frame 211 and are symmetrically distributed up and down along the mounting frame 211. Guide blocks 22 are fixedly connected to the material suction frame 5 and are symmetrically distributed left and right along the guide plates 21. The upper side surfaces of the upper guide blocks 22 and the lower side surfaces of the lower guide blocks 22 are both provided as wedge-shaped surfaces. The guide blocks 22 are in extrusion fit with the adjacent guide plates 21 through the wedge-shaped surfaces. A torsion spring 23 is fixedly connected between the guide plates 21 and the mounting frame 211.

[0043] By pushing the mounting frame 211 forward, the mounting frame 211 drives the material guide plate 21 to move forward. Under the squeezing action of the wedge-shaped surface of the guide block 22, the material guide plate 21 rotates outward and opens. The longer the forward push distance is, the larger the opening between the two material guide plates 21 is. When the forward thrust on the mounting frame 211 is gradually removed, the torsion spring 23 gradually resets, thereby driving the guide plate 9 to rotate inward. The greater the force is removed, the smaller the opening between the two material guide plates 21 is, thus achieving the effect of adjusting the size of the air suction inlet opening. In this way, the opening can be adjusted smaller when a larger suction force is required and adjusted larger when there is more debris.

[0044] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation so as to cover all modifications and equivalent structures and functions.
