The top of the screening frame 101 is movably connected with a swing frame 103. A plurality of groups of springs 105 are connected to the side outer wall of the screening frame 101. The swing frame 103 is connected to the screening frame 101 through the springs 105. A swing seat 106 is arranged at the top diagonal of the swing frame 103. A swing plate 108 is movably installed on the swing seat 106. A tipping bucket 110 is arranged on the top of the swing plate 108. A chute 112 is opened on the side of the swing frame 103. A rack 113 is slidably arranged in the chute 112. A swing column 109 movably arranged in the swing seat 106 is fixedly arranged at the bottom of the tipping bucket 110. A half gear 111 is installed on the outer side of the swing column 109. Both ends of the rack 113 are provided with meshing teeth 114 that cooperate with the half gear 111. The grinding mechanism 2 comprises a conveying roller 201 symmetrically arranged on both sides of the screening frame 101, and a material unloading frame 202 is arranged above the conveying roller 201; a plurality of groups of conveying pulleys 206 arranged at intervals are arranged on the front side of the conveying roller 201, and symmetrical grinding rollers 208 are arranged at both ends of the conveying pulley 206, and a plurality of groups of protrusions 209 located at the intervals of the conveying pulleys 206 are arranged on the grinding roller 208; a support plate 210 is arranged on the conveying roller 201, and a mounting frame 211 is also arranged on the outer side of the conveying pulley 206, and a slide rail 212 located below the conveying roller 201 is fixedly arranged between the support plate 210 and the mounting frame 211; a first slide seat 213 and a second slide seat 214 are slidably arranged on the slide rail 212, and the first slide seat 213 and the second slide seat 214 are fixedly connected and cooperate with each other to grind the two ends of the chopsticks.

[0033] In this embodiment: the external cylindrical machine for chopstick processing is mainly divided into two parts: a screening mechanism 1 and a grinding mechanism 2. When the device is in use, the rough-processed chopsticks are first placed in the tipping bucket 110 and arranged neatly. Then the oscillation motor 121 is started. Under the linkage of the active swing arm 122 and the driven swing arm 123 and the limiting effect on the swing frame 103, the tipping bucket 110 will reciprocate and oscillate slightly left and right, and the cutting debris remaining on the surface of the chopsticks will fall into the debris box 124 below. When it is necessary to unload, the double-axis cylinder 119 and the flip cylinder 115 are started and the tipping bucket 110 is driven to flip to both sides. When the tipping bucket 110 needs to flip to the left side to unload, the double-axis cylinder 119 is started to make the slider 117 on the left side slide inward and limit the swing column 109 on the left side, then the slider 117 on the right side slides outward and disengages from the swing column 109 on the right side, and finally the flip cylinder 115 is started to make the rack 113 slide to the right side. When the tipping bucket 110 needs to turn over to the right side to unload materials, the double-axis cylinder 119 is started to make the right slider 117 slide outward and disengage from the right swing column 109, then the left slider 117 slides inward and limits the left swing column 109, and finally the turning cylinder 115 is started to make the rack 113 slide to the left. After the chopsticks move to the position of the first slide seat 213 along the conveyor belt 203, the first slide seat 213 slides inward along the slide rail 212 under the drive of the swing motor 222. Since the distance between the leftmost limit position of the first grinding wheel 217 and the initial end conveying pulley 206 is less than the length of the chopsticks, when the chopsticks enter the conveying pulley 206, the front end of the chopsticks is located between the protrusions 209, and the first grinding wheel 217 grinds the tail of the chopsticks.

[0034] See attached Figure 2 -Attached Figure 3 A lower convex plate 102 is provided on the side wall of the screening frame 101, an upper convex plate 104 is provided on the side wall of the swing frame 103, and a spring 105 is connected between the lower convex plate 102 and the upper convex plate 104; an oscillation motor 121 is also installed on the screening frame 101, and an active swing arm 122 is connected to the output end of the oscillation motor 121, and a driven swing arm 123 is connected to the side wall of the swing frame 103, and the end of the active swing arm 122 is connected to the swing frame 103 through the driven swing arm 123.

[0035] In this embodiment, in order to automatically drive the swing frame 103 and the tipping bucket 110 to oscillate, a structure of a spring piece 105 and an oscillation motor 121 that cooperate with each other is designed.

[0036] See attached Figure 2 -Attached Figure 4A penetrating sliding cavity 107 is provided on the swing seat 106, and a slider 117 is slidably arranged in the sliding cavity 107. The sliders 117 located on the same side are connected by a connecting plate 118; a double-axis cylinder 119 is installed in the middle of the swing frame 103, and the output end of the double-axis cylinder 119 is fixedly connected to the connecting plates 118 on both sides.

[0037] In this embodiment, since the swing column 109 is movably arranged on the swing seat 106, when the tipping bucket 110 and the swing frame 103 are unloading materials to the left, the left swing column 109 needs to be limited. And when the tipping bucket 110 and the swing frame 103 are unloading materials to the right, the right swing column 109 needs to be limited, so a double-axis cylinder 119 structure is designed, and the swing column 109 is limited by a slider 117.

[0038] See attached Figure 3 A through cavity 116 is provided in the middle of the slide groove 112 , and a flip cylinder 115 is also installed at the bottom of the swing frame 103 . The output end of the flip cylinder 115 passes through the through cavity 116 and is fixedly connected to the rack 113 .

[0039] In this embodiment, in order to drive the rack 113 to slide along the slide groove 112, so as to realize the tipping bucket 110 and the swing frame 103 to flip in different directions, a flipping cylinder 115 structure is designed.

[0040] See attached Figure 3 -Attached Figure 4 A protective cover 120 located above the double-axis cylinder 119 is also installed in the middle of the swing frame 103, and a debris box 124 is also provided at the bottom of the screening frame 101.

[0041] In this embodiment: when the debris falls, in order to prevent the debris from falling onto the swing frame 103 and affecting the subsequent operation of the dual-axis cylinder 119, a protective cover 120 structure is designed.

[0042] See attached Figure 5 and attached Figure 8 A conveyor belt 203 is arranged between the conveyor rollers 201 , a plurality of groups of recessed portions 204 are arranged at intervals on the conveyor belt 203 , and a groove 207 is arranged in the middle of the conveyor pulley 206 .

[0043] In this embodiment, the width of the conveyor belt 203 is smaller than the length of the chopsticks, and the distance between the bottom of the feeding frame 202 and the conveyor belt 203 is smaller than the diameter of the chopsticks, so when the chopsticks in the feeding frame 202 fall into the recessed portion 204, they can be conveyed out of the feeding frame 202. During the grinding operation, in order to improve the conveying efficiency of the conveying pulley 206, a groove 207 structure is designed.

[0044] See attached Figure 5 -Attached Figure 8A vertical plate 215 is provided on the first slide 213, a first grinding motor 216 is installed on the outer side of the vertical plate 215, and a first grinding wheel 217 is provided at the output end of the first grinding motor 216; a vertical plate 218 is provided on the second slide 214, a second grinding motor 219 is installed on the outer side of the vertical plate 218, and a second grinding wheel 220 is provided at the output end of the second grinding motor 219; the vertical plate 215 is fixedly connected to the vertical plate 218 through a connecting rod 221.

[0045] In this embodiment: after the chopsticks move along the conveyor belt 203 to the position of the first slide 213, the first slide 213 slides inward along the slide rail 212 under the drive of the swing motor 222. Since the distance between the leftmost limit position of the first grinding wheel 217 and the initial end conveying pulley 206 is smaller than the length of the chopsticks, when the chopsticks enter the conveying pulley 206, the front end of the chopsticks is located between the protrusions 209, and the first grinding wheel 217 grinds the tail of the chopsticks.

[0046] See attached Figure 5 -Attached Figure 6 A swing motor 222 is installed on the side of the support plate 210, and the output end of the swing motor 222 is connected to a short swing arm 223. A long swing arm 224 is movably connected to the side of the first slide 213, and the short swing arm 223 is movably connected to the first slide 213 through the long swing arm 224.

[0047] In this embodiment, in order to drive the first slide 213 to reciprocate along the slide rail 212 so as to cooperate with the second slide 214 to grind the two ends of the chopsticks, a swing motor 222 structure is designed.

[0048] See attached Figure 8 The sides of the conveying roller 201 are connected to each other by a belt 205.

[0049] In this embodiment, in order to drive the conveying roller 201 to rotate, thereby automatically feeding and conveying the chopsticks in the feeding frame 202, a belt 205 structure is designed.

[0050] See attached Figure 5 and attached Figure 7 A collection box 225 is provided below the slide rails 212 on both sides.

[0051] In this embodiment: after the chopsticks move to the end of the conveying pulley 206, the first slide 213 retracts to the initial position. Since the first slide 213 is fixedly connected to the second slide 214, and the length of the chopsticks is greater than the distance between the second slide 214 and the end conveying pulley 206, the ends of the chopsticks are located between the protrusions 209, and the second grinding wheel 220 grinds the front of the chopsticks. When the first slide 213 slides inward again along the slide rail 212, the distance between the second slide 214 and the end conveying pulley 206 is greater than the length of the chopsticks, and the chopsticks fall into the collection box 225 below.

[0052] In this embodiment: when the device is in use, the rough-processed chopsticks are first placed in the tipping bucket 110 and arranged neatly. Then the oscillation motor 121 is started, and under the linkage of the active swing arm 122 and the driven swing arm 123 and the limiting effect on the swing frame 103, the tipping bucket 110 will reciprocate and oscillate slightly left and right, and the cutting debris remaining on the surface of the chopsticks will fall into the debris box 124 below. When it is necessary to unload materials, the double-axis cylinder 119 and the flip cylinder 115 are started and the tipping bucket 110 is driven to flip to both sides. When the tipping bucket 110 needs to flip to the left side to unload materials, the double-axis cylinder 119 is started to make the slider 117 on the left side slide inward and limit the swing column 109 on the left side, and then the slider 117 on the right side slides outward and disengages from the swing column 109 on the right side, and finally the flip cylinder 115 is started to make the rack 113 slide to the right side. When the tipping bucket 110 needs to flip to the right side to unload, the double-axis cylinder 119 is started to make the slider 117 on the right side slide outward and disengage from the swing column 109 on the right side, then the slider 117 on the left side slides inward and limits the swing column 109 on the left side, and finally the flipping cylinder 115 is started to make the rack 113 slide to the left side. After the chopsticks move to the position of the first slide seat 213 along the conveyor belt 203, the first slide seat 213 slides inward along the slide rail 212 under the drive of the swing motor 222. Since the distance between the leftmost limit position of the first grinding wheel 217 and the initial end conveying pulley 206 is less than the length of the chopsticks, when the chopsticks enter the conveying pulley 206, the front end of the chopsticks is located between the protrusions 209, and the first grinding wheel 217 grinds the tail of the chopsticks. When the chopsticks move to the end of the conveying pulley 206, the first slide seat 213 retracts to the initial position. Since the first slide 213 is fixedly connected to the second slide 214, and the length of the chopsticks is greater than the distance between the second slide 214 and the terminal conveying pulley 206, the ends of the chopsticks are located between the protrusions 209, and the second grinding wheel 220 grinds the front of the chopsticks. When the first slide 213 slides inward again along the slide rail 212, the distance between the second slide 214 and the terminal conveying pulley 206 is greater than the length of the chopsticks, and the chopsticks fall into the collection box 225 below.
