DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] In one embodiment, see Figure 1 , Figure 2 and Figure 4, a grinding and polishing device suitable for a rubber roller of a printer comprises a moving frame 11 and a plurality of vertical plates 2, a placing box 1 and a top plate 3 are fixed on the top of the vertical plate 2, and the placing box 1 is tilted downward at one end close to the top plate 3, and a rotating frame 10 which is symmetrically distributed is arranged on the inner side of the moving frame 11, and a placing groove 9 is arranged on the inner wall of the rotating frame 10, and a fixing mechanism 7 is arranged inside the placing groove 9, and the fixing mechanism 7 is used to clamp and fix the metal cores at both ends of the rubber roller, and the moving frame 11 is connected to the vertical plate 2 through a moving mechanism 4, and the rotating frame 10 is connected to the moving frame 11 through a rotating mechanism 6, and the moving mechanism 4 is used to drive the moving frame 11 to reciprocate, and during the movement of the moving frame 11, the rotating mechanism 6 is used to drive the rotating frame 10 to rotate, and a polishing mechanism 8 is arranged on the side of the moving frame 11, and the polishing mechanism 8 is used to polish the rubber roller during the rotation process, wherein an ejection mechanism 5 is arranged inside the placing box 1, and the ejection mechanism 5 is used to eject the rubber roller inside the placing box 1 to between the rotating frames 10.

[0029] In this embodiment, when the device is polishing the rubber roller, multiple rubber rollers are placed in the placement box 1, and the bottom rubber roller is ejected from the placement box 1 by the ejection mechanism 5. After being ejected, the rubber roller slides along the top of the placement box 1 to between the rotating frames 10, wherein the metal cores at both ends of the rubber roller will fall into the placement grooves 9 on the inner walls of the two rotating frames 10 respectively, and the placement grooves 9 support the metal cores, thereby supporting the rubber roller. After the rotating frame 10 has supported the rubber roller, the moving frame 11 is driven to move by the moving mechanism 4, and the moving frame 11 drives the rotating frame 10 to move. When the rotating frame 10 moves to a certain position, the fixing mechanism 7 inside the placement groove 9 will automatically fix the metal cores at both ends of the rubber roller, thereby improving the stability of the rubber roller, so that the rubber roller can rotate with the rotating frame 10. When the rubber roller is fixed, the moving mechanism 4 continues to drive the moving frame 11 to move. At this time, the polishing mechanism 8 on the side of the moving frame 11 automatically polishes the surface of the rubber roller, thereby improving the smoothness of the surface of the rubber roller, and the polishing mechanism 8 polishes the surface of the rubber roller. During polishing, the rotating mechanism 6 drives the rubber roller to rotate through the rotating frame 10 while the mobile frame 11 moves, so that the polishing mechanism 8 can fully polish the surface of the rubber roller, effectively improving the polishing effect of the rubber roller. When the rotating mechanism 6 drives the rotating frame 10 to rotate n+0.5 (n≥1) circles, the placement groove 9 on the side wall of the rotating frame 10 is located below. At this time, the fixing mechanism 7 no longer fixes the metal core at the end of the rubber roller. Without the fixation of the fixing mechanism 7, the polished rubber roller automatically falls from between the rotating frames 10, thereby achieving the purpose of unloading. Subsequently, the polishing mechanism 8 stops running, and the mobile mechanism 4 drives the mobile frame 11 to move back. When the rotating frame 10 moves to the bottom of the placement box 1, the ejection mechanism 5 ejects the rubber roller at the bottom of the placement box 1 again, and the ejected rubber roller falls again inside the placement groove 9 between the rotating frames 10. This cycle is repeated, achieving the purpose of automatic loading and unloading of the rubber roller and automatic polishing. The entire process does not require the participation of staff, saving manpower, and can achieve continuous polishing of the rubber roller, thereby improving the polishing efficiency of the rubber roller.

[0030] See also Figure 1 and Figure 2 The moving mechanism 4 includes a first motor 44 fixed on one of the vertical plates 2, a threaded rod 42 is installed at the output end of the first motor 44, the threaded rod 42 is rotatably connected to the vertical plates 2, a guide rod 43 is fixed between the vertical plates 2, and symmetrically distributed moving blocks 41 are fixed on the side wall of the moving frame 11, the guide rod 43 passes through one of the moving blocks 41 and is slidably connected to the moving block 41, and the threaded rod 42 passes through the other moving block 41 and is threadedly connected to the moving block 41;

[0031] When the supporting mechanism pushes the rubber roller out to between the rotating frames 10, the first motor 44 drives the threaded rod 42 to rotate, and the threaded connection between the threaded rod 42 and the moving block 41 drives the moving frame 11 to move, and the moving frame 11 drives the rubber roller to move horizontally through the rotating frame 10, so that the fixing mechanism 7 can fix the rubber roller, and the rotating mechanism 6 drives the rotating frame 10 to rotate. When the rubber roller is polished and falls from between the rotating frames 10, the first motor 44 drives the threaded rod 42 to reverse, so that the moving frame 11 drives the rotating frame 10 to move back, wherein the first motor 44 can be a forward and reverse motor, and the guide rod 43 can play a limiting role on the moving frame 11 through the moving block 41, which effectively improves the stability of the moving frame 11 when moving.

[0032] See also Figure 2 and Figure 3 The ejection mechanism 5 includes a first trapezoidal block 53 disposed below the placement box 1, a push rod 51 is fixed to the top of the first trapezoidal block 53, the push rod 51 passes through the bottom of the placement box 1, and a first elastic member 52 is provided outside the push rod 51, and both ends of the first elastic member 52 are respectively fixedly connected to the bottom of the placement box 1 and the top of the first trapezoidal block 53, wherein a push plate 54 capable of squeezing the inclined surface of the first trapezoidal block 53 is fixed on the side wall of the moving frame 11;

[0033] After the rubber roller is polished, the moving mechanism 4 drives the moving frame 11 and the rotating frame 10 to move back. When the rotating frame 10 moves to the bottom of the placement box 1, the push plate 54 on the side wall of the moving frame 11 squeezes the inclined surface of the first trapezoidal block 53, so that the first trapezoidal block 53 drives the push rod 51 to move upward. The push rod 51 moves upward and pushes the rubber roller at the bottom of the placement box 1. When the rubber roller is pushed out to the top of the placement box 1, the rubber roller automatically slides along the top of the placement box 1 to the rotating frame 10. At this time, the placement groove 9 on the inner wall of the rotating frame 10 supports the metal core at the end of the rubber roller. This plays a supporting role for the rubber roller. In order to enable the metal core at the end of the rubber roller to accurately fall into the placement groove 9, one of the inner walls of the placement groove 9 has a slope. When the rubber roller slides from the top of the placement box 1, the metal core at the end of the rubber roller will slide along the slope on the side wall of the placement groove 9 to the inside of the placement groove 9. When the rotating frame 10 has completed supporting the rubber roller, the moving mechanism 4 drives the moving frame 11 away from the placement box 1, and the push plate 54 no longer squeezes the first trapezoidal block 53. The first trapezoidal block 53 drives the push rod 51 to move downward under the action of the first elastic member 52, wherein the first elastic member 52 can be a spring.

[0034] See also Figure 2 and Figure 4The rotating mechanism 6 includes rotating rods 62 fixed on the outer wall of the rotating frame 10 and symmetrically distributed, and the rotating rods 62 are rotatably connected to the inner wall of the mobile frame 11, one end of the rotating rod 62 passes through the side wall of the mobile frame 11 and is fixedly connected to a gear 61, and a toothed plate 63 capable of meshing with the gear 61 is fixed at the bottom of the top plate 3;

[0035] After the fixing mechanism 7 has fixed the rubber roller, the polishing mechanism 8 starts to polish the rubber roller. As the moving frame 11 continues to move, the gear 61 at the end of one of the rotating rods 62 will engage with the tooth plate 63 at the bottom of the top plate 3. The engagement of the tooth plate 63 with the gear 61 drives the rotating rod 62 to rotate. The rotating rod 62 drives the rubber roller to rotate through the rotating frame 10, so that the rubber roller can also rotate during the forward movement, thereby enabling the polishing mechanism 8 to fully polish the rubber roller, effectively improving the polishing effect of the rubber roller.

[0036] See also Figure 5 and Figure 6 The fixing mechanism 7 includes grooves arranged on the inner wall of the placement groove 9 and distributed symmetrically, and a clamping block 71 is slidably connected inside the groove. The sides of the clamping blocks 71 close to each other are each provided with an arc groove adapted to the metal core at the end of the rubber roller, wherein the clamping block 71 is connected to a driving component, and the driving component is used to drive the clamping block 71 to move in a mirror image;

[0037] After the metal core at the end of the rubber roller falls into the placement groove 9, the driving component drives the rubber roller to move through the mobile frame 11 and the rotating frame 10. When the mobile frame 11 moves to a certain position, the driving component drives the two clamping blocks 71 to approach each other synchronously until the arc groove on the side wall of the clamping block 71 fits tightly with the metal core. The metal core is pressed and held in the placement groove 9 by the two symmetrically distributed clamping blocks 71, which effectively improves the stability of the rubber roller, so that the rubber roller can rotate with the rotating frame 10, and the symmetrically distributed clamping blocks 71 can also play a positioning role for the rubber roller, thereby ensuring that the rubber roller It can be located at the center of the rotating frame 10. As the mobile frame 11 continues to move, when the mobile frame 11 rotates n+0.5 circles, the placement slot 9 moves to the bottom. At this time, the driving component drives the two clamping blocks 71 to move away from each other, and the clamping block 71 no longer fixes the metal core at the end of the rubber roller. The rubber roller automatically separates from the rotating frame 10 under the action of gravity. When polishing the rubber roller, there is no need to manually fix the rubber roller between the rotating frames 10, and there is no need to manually remove the polished rubber roller from the rotating frames 10, which saves manpower and effectively improves the polishing efficiency of the rubber roller.

[0038] See also Figure 4 , Figure 5 and Figure 6The first end of the second end of the first ...

[0039] When the metal core at the end of the rubber roller falls into the placement groove 9, the driving component drives the rubber roller to move through the moving frame 11 and the rotating frame 10. When the moving frame 11 moves to a certain position, the first magnet 79 on the top of the baffle 78 moves below the second magnet 710, and the second magnet 710 and the first magnet 79 repel each other, so that the first magnet 79 drives the baffle 78 and the first support rod 75 to move downward. While the first support rod 75 moves downward, it pushes the slide plate 72 through the first connecting rod 74. The slide plate 72 drives the clamping block 71 to approach each other, so that the clamping block 71 can fix the metal core at the end of the rubber roller. When the clamping block 71 fixes the metal core, the rotating frame 10 The fixing components inside the movable frame 10 will automatically fix the slide plate 72, thereby fixing the clamping block 71, effectively ensuring the fixing effect of the clamping block 71 on the metal core. As the movable frame 11 continues to move, when the movable frame 11 rotates n+0.5 circles, the placement slot 9 moves downward. At this time, the fixing components automatically release the fixation of the slide plate 72, and the baffle plate 78 drives the first support rod 75 to move upward under the action of the second elastic member 77. The second elastic member 77 can be a spring. When the first support rod 75 moves upward, it pulls the slide plate 72 through the first connecting rod 74, so that the two clamping blocks 71 move away from each other, thereby releasing the fixation of the clamping block 71 on the metal core.

[0040] See also Figure 5 and Figure 6 The fixing member includes a pin rod 713 that passes through the bottom of the rotating frame 10, the pin rod 713 is slidably connected to the rotating frame 10, a support plate 714 is fixed to the bottom of the pin rod 713, a third elastic member 715 is provided outside the pin rod 713, and the two ends of the third elastic member 715 are respectively fixedly connected to the support plate 714 and the bottom of the rotating frame 10, wherein the slide plate 72 is provided with a pin groove 73 that is adapted to the pin rod 713, and the support plate 714 is connected to a traction member, which is used to pull the pin rod 713 to the outside of the pin groove 73;

[0041] When the clamping block 71 has fixed the metal core, the pin groove 73 inside the slide plate 72 is aligned with the pin rod 713. Under the action of the third elastic member 715 and the support plate 714, the end of the pin rod 713 automatically enters the pin groove 73 inside the slide plate 72. At this time, the pin rod 713 fixes the slide plate 72 through the pin groove 73, thereby ensuring the fixed clamping effect of the clamping block 71 on the metal core. When the movable frame 11 rotates n+0.5 circles, the placement slot 9 moves to the bottom. At this time, the traction member pulls the support plate 714, thereby pulling the pin rod 713 to the outside of the pin groove 73. The fixation of the pin rod 713 is lost, and the slide plate 72 drives the clamping block 71 to automatically reset, thereby releasing the fixation of the clamping block 71 to the metal core. The third elastic member 715 can be a spring.

[0042] See also Figure 4 and Figure 6 , the traction member includes a third magnet 711 fixedly connected to the support plate 714, wherein a fourth magnet 712 capable of attracting the third magnet 711 is fixed on the top of the top plate 3;

[0043] When the movable frame 11 rotates n+0.5 circles, the placement slot 9 moves downward and the support plate 714 rotates upward. At this time, the third magnet 711 on the surface of the support plate 714 and the fourth magnet 712 at the bottom of the top plate 3 attract each other. Under the action of the fourth magnet 712, the third magnet 711 drives the pin rod 713 to move through the support plate 714, thereby pulling the pin rod 713 out of the pin slot 73, so that the polished rubber roller can automatically fall off from the rotating frame 10, wherein the fourth magnet 712 can be detachably connected to the top plate 3, thereby changing the position where the third magnet 711 and the fourth magnet 712 attract each other, thereby regulating the number of rotations of the rubber roller.

[0044] See also Figure 7 The polishing mechanism 8 includes a fixed frame 810 fixedly connected to the mobile frame 11, a support frame 83 is provided inside the fixed frame 810, a polishing roller 81 is rotatably connected inside the support frame 83, a second motor 82 is fixed on the side wall of the support frame 83, an output end of the second motor 82 is fixedly connected to one end of the polishing roller 81, the support frame 83 is connected to the fixed frame 810 through a pushing component, and the pushing component is used to push the support frame 83, so that the polishing roller 81 can polish the rubber roller;

[0045] After the rubber roller is fixed, the polishing roller 81 is driven to rotate by the second motor 82, and as the movable frame 11 continues to move, the pushing assembly pushes the support frame 83, and the support frame 83 drives the polishing roller 81 to move in the direction of the rubber roller until the polishing roller 81 contacts the surface of the rubber roller. At this time, the rubber roller can be polished by the polishing roller 81 to improve the smoothness of the rubber roller surface.

[0046] See also Figure 4 and Figure 7 The pushing assembly includes a push rod 84 fixedly connected to the support frame 83 and symmetrically distributed, the push rod 84 penetrates the fixed frame 810 and is slidably connected to the fixed frame 810, one end of the push rod 84 away from the support frame 83 is rotatably connected to the second connecting rod 85, and the other end of the second connecting rod 85 is rotatably connected to the second support rod 86, a second limiting plate 89 is fixed on the side wall of the fixed frame 810, the second support rod 86 penetrates the second limiting plate 89 and is slidably connected to the second limiting plate 89, a pressing plate 88 is fixed on the top of the second support rod 86, and a second trapezoidal block 811 capable of squeezing the pressing plate 88 is fixed on the bottom of the top plate 3, and a fourth elastic member 87 is provided on the outside of the second support rod 86, and the two ends of the fourth elastic member 87 are respectively fixedly connected to the pressing plate 88 and the second limiting plate 89;

[0047] After the rubber roller is fixed, the polishing roller 81 is driven to rotate by the second motor 82, and as the moving frame 11 continues to move, the inclined surface of the second trapezoidal block 811 presses the pressure plate 88, so that the pressure plate 88 drives the second support rod 86 to move downward. While the second support rod 86 moves downward, the push rod 84 is driven to move horizontally through the second connecting rod 85. The push rod 84 pushes the support frame 83, so that the polishing roller 81 can contact the surface of the rubber roller and complete the polishing of the rubber roller. When the rubber roller is polished, it is removed from the rotating frame 11. 0, the moving mechanism 4 drives the moving frame 11 to move back. When the moving frame 11 moves back to a certain position, the second trapezoidal block 811 no longer squeezes the pressure plate 88. The pressure plate 88 drives the second support rod 86 to move upward under the action of the fourth elastic member 87. The fourth elastic member 87 can be a spring. The second support rod 86 drives the polishing roller 81 away from the rotating frame 10 through the second connecting rod 85, the push rod 84 and the support frame 83, thereby avoiding the interference of the polishing roller 81 on the rubber roller entering the inner side of the rotating frame 10.

[0048] Working principle: When the equipment is polishing the rubber roller, the metal core at the end of the rubber roller is supported by the placement groove 9 between the rotating frame 10, and the moving frame 11 is driven to move through the threaded connection between the threaded rod 42 and the moving block 41. The moving frame 11 drives the rubber roller to move through the rotating frame 10. When the moving frame 11 moves to a certain position, the first magnet 79 on the top of the baffle 78 moves to below the second magnet 710, and the second magnet 710 and the first magnet 79 repel each other, so that the first magnet 79 drives the baffle 78 and the first support rod 75 to move downward. While the first support rod 75 moves downward, it pushes the slide plate 72 through the first connecting rod 74, and the slide plate 72 drives the clamping block 71 to approach each other until the clamping block 71 completes the fixation of the metal core. When the metal core is fixed, the pin rod 713 automatically enters the pin groove 73 inside the slide plate 72. At this time, the pin rod 713 fixes the slide plate 72 through the pin groove 73, and then The clamping block 71 ensures the fixing and clamping effect of the metal core. After the rubber roller is fixed, as the mobile frame 11 continues to move, the inclined surface of the second trapezoidal block 811 squeezes the pressure plate 88, so that the pressure plate 88 drives the second support rod 86 to move downward. While the second support rod 86 moves downward, it drives the push rod 84 to move horizontally through the second connecting rod 85. The push rod 84 pushes the support frame 83, so that the polishing roller 81 can contact the surface of the rubber roller. When polishing the rubber roller, as the mobile frame 11 continues to move, the gear 61 at the end of one of the rotating rods 62 will mesh with the tooth plate 63 at the bottom of the top plate 3, and the meshing of the tooth plate 63 and the gear 61 drives the rotating rod 62 to rotate. The rotating rod 62 drives the rubber roller to rotate through the rotating frame 10, so that the rubber roller can also rotate during the forward process, so that the polishing mechanism 8 can fully polish the rubber roller, effectively improving the polishing effect of the rubber roller. When the mobile frame 11 rotates n+0.When the locking cam 714 is in the locked state, the locking cam 714 is in the locked state, and the locking cam 714 is in the locked state. The push plate 54 on the side wall of the frame 11 squeezes the inclined surface of the first trapezoidal block 53, so that the first trapezoidal block 53 drives the push rod 51 to move upward. The push rod 51 moves upward and pushes the rubber roller at the bottom of the placement box 1. When the rubber roller is pushed out to the top of the placement box 1, the rubber roller automatically slides along the top of the placement box 1 to the rotating frame 10. At this time, the placement groove 9 on the side wall of the rotating frame 10 supports the metal core at the end of the rubber roller, thereby supporting the rubber roller. This cycle is repeated to achieve the purpose of automatic loading and unloading and automatic polishing of the rubber roller. The whole process does not require the participation of staff, saving manpower, and can achieve continuous polishing of the rubber roller, improving the polishing efficiency of the rubber roller.
