All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work fall within the scope of protection of the present utility model.
[0023] As Figures 1-4As shown in the figure, the present utility model provides a technical solution: a detachable tool grinding device for paper cutting, including a base 1. A support rod 101 is fixedly connected to the top end of the base 1, and a workbench 102 is fixedly connected to the top of the support rod 101. A material discharge groove 103 is opened at the center of the interior of the workbench 102. A grinding wheel 104 is fixedly connected to one side of the inner wall of the material discharge groove 103. Sliding grooves 2 are opened on both sides of the material discharge groove 103. A slider 201 is movably connected to the interior of the sliding groove 2. A placement rack 202 is fixedly connected to the top outer wall of the slider 201. Gripping rods 203 are fixedly connected to both outer walls of the placement rack 202. A movable piece 204 is movably connected to the outer side of the top of the placement rack 202. A cylinder 205 is fixedly connected to the bottom of the movable piece 204. A linkage block 206 is fixedly connected to the bottom end of the cylinder 205. Tooth grooves 207 are opened on both sides of the linkage block 206. A gear 208 is movably connected to the outer wall of the tooth groove 207. A fastener 209 is movably connected to the outer side of one end of the gear 208. A connecting rod 210 is fixedly connected to the outer wall of the bottom end of the gear 208. A clamping piece 211 is fixedly connected to the bottom side of the connecting rod 210. A groove 212 is opened on the surface of the clamping piece 211. A paper cutting blade 213 is movably connected to the inner wall of the clamping piece 211. A material discharge pipe 3 is vertically fixedly connected between the workbench 102 and the base 1 through the bottom end of the material discharge groove 103. A leakage groove 301 is opened in the interior of the material discharge pipe 3. A filter screen 302 is fixedly connected to the inner surface of the leakage groove 301. A blower 303 is arranged at the bottom end of the filter screen 302. A movable door 304 is movably connected to one outer wall of the material discharge pipe 3.
[0024] According to the overall structure of the device, when the device is working, the staff places the disassembled paper cutting blade 213 between the clamping pieces 211 on both sides of the top of the blanking chute 103. At this time, both the clamping piece 211 and the gear 208 are in their initial positions. At the same time, the air cylinder 205 is started, causing the air cylinder 205 to start rising. The air cylinder 205 drives the linkage block 206 to start rising. When the linkage block 206 rises, the tooth grooves 207 on both sides engage with the gear 208, causing the two gears 208 to rotate upward in the relative direction inside at the same time. When the gear 208 rotates, it is limited by the fastener 209. When the gear 208 rotates, the connecting rod 210 at the bottom starts to drive the clamping piece 211 to move closer to the inside. As the clamping piece 211 gets closer and closer, finally the upper part of the paper cutting blade 213 is clamped at the center. The groove 212 on the inner wall of the clamping piece 211 increases the friction between the surface and the paper cutting blade 213. After the clamping work of the paper cutting blade 213 is completed, the motor 105 is started to make the grinding wheel 104 start working. At the same time, the staff manipulates the grip 203 to make the placement rack 202 drive the paper cutting blade 213 closer to the grinding wheel 104 to grind the bottom of the paper cutting blade 213. When it is necessary to grind both sides of the paper cutting blade 213, only the movable piece 204 at the top needs to be moved, so that the movable piece 204 drives the paper cutting blade 213 to slide horizontally along the grinding wheel 104 for grinding. When the grinding wheel 104 is performing the grinding work, the blower 303 is turned on. The blower 303 rotates to generate suction, and the debris generated by the paper cutting blade 213 falls downward under the action of gravity and the blower 303, so that the debris falls from the blanking chute 103 into the internal part of the bottom leakage trough 301. Larger debris is intercepted by the filter screen 302 at the top of the blower 303. After all, large particles entering the blower 303 will affect its normal operation. After the grinding work is completed, the staff opens the movable door 304 to clean the large particles above the filter screen 302.
[0025] As Figures 1-4As shown in the figure, the linkage block 206 and the gear 208 form a lifting structure through the cylinder 205. The tooth grooves 207 are symmetrically arranged on both sides of the linkage block 206. The meshing transmission is between the tooth grooves 207 and the gear 208. The gear 208 is rotatably connected to one end of the fastener 209, and the other side of the fastener 209 is fixed to the inner wall of the placement rack 202. The gears 208 are symmetrically distributed on both sides of the linkage block 206 through the fasteners 209. The connecting rod 210 is fixed below the gear 208. There are two groups of connecting rods 210 symmetrically arranged, and the connecting rods 210 are both inclined inward. The clamping piece 211 is trapezoidal. The grooves 212 are evenly arranged on the surface of the clamping piece 211. The outer walls on both sides of the paper cutting blade 213 are closely attached to the inner wall of the clamping piece 211. The grooves 212 and the paper cutting blade 213 are both arranged inside the blanking chute 103. The clamping piece 211 and the paper cutting blade 213 form a rotating structure through the cooperation of the gear 208, the tooth groove 207 and the linkage block 206. The sliding grooves 2 are symmetrically arranged at the top of the workbench 102. The placement rack 202 is slidably connected to the sliding grooves 2 through the sliders 201. The placement rack 202 is a hollow rectangle. There is a set of movable pieces 204, and a set of movable pieces 204 are fixedly connected to each other. The movable pieces 204 are slidably connected to the top of the placement rack 202. The outer surface of the grinding wheel 104 is fixedly connected to the motor 105, and the motor 105 passes through the inner wall of the workbench 102 and is connected to the grinding wheel 104.
[0026] The cylinder 205 drives the linkage block 206 to start rising. When the linkage block 206 rises, the tooth grooves 207 on both sides are engaged with the gear 208, so that the two gears 208 rotate upward in the relative direction inside at the same time. When the gear 208 rotates, it is limited by the fastener 209. When the gear 208 rotates, the connecting rod 210 at the bottom starts to drive the clamping piece 211 to move closer to the inside. As the clamping piece 211 gets closer and closer, finally the upper part of the paper cutting blade 213 is clamped at the center. The grooves 212 on the inner wall of the clamping piece 211 increase the friction between the surface and the paper cutting blade 213. After the clamping work of the paper cutting blade 213 is completed, the motor 105 is started to make the grinding wheel 104 start to work. At the same time, the staff manipulates the grip 203 to make the placement rack 202 drive the paper cutting blade 213 closer to the grinding wheel 104 to grind the bottom of the paper cutting blade 213. When it is necessary to grind both sides of the paper cutting blade 213, only need to move the movable piece 204 at the top, so that the movable piece 204 drives the paper cutting blade 213 to slide horizontally along the grinding wheel 104 for grinding.
[0027] As Figures 1-4 shown in the figure, the leakage groove 301 is in an inverted cone shape. The leakage groove 301 is connected to the blanking chute 103 through. The blower 303 is rotatably connected to the center of the bottom of the leakage groove 301. There is a slot on one side inside the blanking pipe 3. The slot is arranged on the top of the filter screen 302. The movable door 304 is snap-connected to the outer wall of the blanking pipe 3.
[0028] By rotating the fan 303 to generate suction, the debris generated by the paper cutting blade 213 falls downward under the action of gravity and the fan 303, so that the debris falls from the feeding chute 103 into the internal part of the bottom leakage trough 301. Larger debris is intercepted by the filter screen 302 at the top of the fan 303. After all, large particles entering the inside of the fan 303 will affect its normal operation. After the grinding work is completed, the staff opens the movable door 304 to clean the large particles above the filter screen 302.
[0029] Working principle: When the device is working, the staff places the disassembled paper cutting blade 213 between the clamping pieces 211 on both sides of the top of the feeding chute 103. At this time, both the clamping pieces 211 and the gear 208 are in their initial positions. At the same time, the air cylinder 205 is started, so that the air cylinder 205 starts to rise. The air cylinder 205 drives the linkage block 206 to start rising. When the linkage block 206 rises, the tooth grooves 207 on both sides are engaged with the gear 208, so that the two gears 208 rotate upward in the relative direction inside at the same time. When the gear 208 rotates, it is limited by the fastener 209. When the gear 208 rotates, the connecting rod 210 at the bottom starts to drive the clamping pieces 211 to move closer to the inside. As the clamping pieces 211 get closer and closer, finally the upper part of the paper cutting blade 213 is clamped at the center. The groove 212 on the inner wall of the clamping piece 211 increases the friction force between the surface and the paper cutting blade 213. After the clamping work of the paper cutting blade 213 is completed, the motor 105 is started, so that the grinding wheel 104 starts to work. At the same time, the staff manipulates the grip rod 203 to drive the placement rack 202 to drive the paper cutting blade 213 to approach the grinding wheel 104, and grind the bottom of the paper cutting blade 213. When it is necessary to grind both sides of the paper cutting blade 213, only need to move the movable piece 204 at the top, so that the movable piece 204 drives the paper cutting blade 213 to slide horizontally along the grinding wheel 104 for grinding;
[0030] When the grinding wheel 104 is performing grinding work, the fan 303 is turned on. The fan 303 rotates to generate suction. The debris generated by the paper cutting blade 213 falls downward under the action of gravity and the fan 303, so that the debris falls from the feeding chute 103 into the internal part of the bottom leakage trough 301. Larger debris is intercepted by the filter screen 302 at the top of the fan 303. After all, large particles entering the inside of the fan 303 will affect its normal operation. After the grinding work is completed, the staff opens the movable door 304 to clean the large particles above the filter screen 302.
