[0002] Composite paper tubes are objects made of paper into a tube shape. They have the advantages of high strength and low cost. Composite paper tubes are used in many fields such as chemical fiber, film, printing, metallurgy, etc. After the composite paper tube is manufactured, its performance needs to be tested. The most important performance is the compressive performance. The composite paper tube compression test is an important experiment to evaluate the strength and stability of the paper tube under pressure.

[0004] Furthermore, the conveying device also includes an end roller, a transfer roller and a plurality of conveying rollers rotatably mounted on the paper tube box, and transmission gears are fixedly mounted on the end roller, the transfer roller and the conveying roller, and transmission belts are wrapped around the outside of all the transmission gears. Composite paper tubes are stacked in the paper tube box, and the lowest composite paper tube is located on the active roller and the conveying roller.

[0005] Furthermore, a conveying motor is arranged beside the paper tube box, a motor gear is fixedly mounted on the motor shaft of the conveying motor, an upper transmission wheel is fixedly mounted on the outer half-tooth gear, and a conveyor belt is wrapped around the motor gear and the upper transmission wheel.

[0006] Furthermore, the paper tube box is rotatably equipped with an inner butt gear and an end butt gear, the inner butt gear is fixedly equipped with an outer butt gear, the end roller is fixedly equipped with an end gear, the transfer roller is fixedly equipped with a transfer gear, the transfer gear is meshed with the inner butt gear, and the end gear is meshed with the end butt gear.

[0007] The rotation of the conveying motor drives the motor gear to rotate, which drives the upper transmission wheel, the outer half-tooth gear and the inner missing-tooth gear to rotate through the conveyor belt. The rotation of the outer half-tooth gear drives the active gear and the active roller to rotate intermittently. The active roller drives the transmission gear to rotate, and drives the transfer roller, the end roller and all the conveying rollers to rotate through the transfer belt, so that the composite paper tube at the bottom of the paper tube box is transported toward the moving frame. At the same time, the rotation of the end roller drives the end docking gear to rotate through the end gear. The transfer roller drives the inner docking gear and the outer docking gear to rotate through the transfer gear. The rotation of the inner missing-tooth gear drives the rotating rod gear to rotate, thereby driving the long rotating rod to rotate through the fixed rotating rod, thereby driving the moving frame to move back and forth through the roller. The inner missing-tooth gear meshes with the rotating rod gear each time, driving the rotating rod gear to rotate half a circle. When the long rotating rod drives the moving frame to approach the paper tube box, the end docking The gear is meshed with the dynamic docking gear, and the outer docking gear is meshed with the front docking wheel. At this time, the inner toothless gear is disengaged from the rotating rod gear, and the rotation of the end docking gear drives the dynamic docking gear to rotate, and the rotation of the outer docking gear drives the front docking wheel to rotate. The rotation of the dynamic docking gear drives the outer roller to rotate, and drives all the inner rollers to rotate through the connecting transmission belt. The composite paper tube is transported to the inner roller through the rotation of the conveying roller, the end roller, the transfer roller, the outer roller and the inner roller. When the composite paper tube is transported, the mobile frame starts to move away from the paper tube box, and the next composite paper tube falls on the conveying roller. When the next composite paper tube is transported to the end roller, the outer half-tooth gear is disengaged from the driving gear. When the next end docking gear rotates half a circle to drive the mobile frame to move toward the paper tube box, the outer half-tooth gear starts to mesh with the driving gear again.

[0008] Furthermore, the docking device also includes an outer roller and four inner rollers rotatably mounted on the mobile frame, the outer roller and the four inner rollers are wrapped with connecting transmission belts, a dynamic docking gear is fixedly mounted on the outer roller, a rear transmission column and a front docking wheel are rotatably mounted on the mobile frame, and a transmission belt is wrapped around the rear transmission column and the front docking wheel.

[0010] When the mobile frame moves to the side of the paper tube box, the end docking gear drives the dynamic docking gear to rotate, the outer docking gear drives the front docking wheel to rotate, and the rotation of the front docking wheel drives the toggle gear and the toggle half-column to rotate. At this time, the composite paper tube has reached the outer roller and the four inner rollers. In the initial state, the striking spring is in a compressed state. As the toggle gear and the toggle half-column rotate, the toggle half-column disengages from the toggle arc surface, and the striking spring rebounds, driving the striking hammer to pop out. The composite paper tube is subjected to a compression test by the striking hammer. Then the toggle half-column continues to rotate and pushes the striking hammer to slide along the mobile frame through the toggle arc surface. When the striking spring is compressed to the tightest, the inner toothless gear begins to engage with the rotating rod gear again, and the mobile frame is driven away from the paper tube box through the long rotating rod. When the mobile frame reaches the farthest point, the inner toothless gear disengages from the rotating rod gear, and the composite paper tube falls onto the tube outlet slope due to gravity, and finally falls onto the detection slope frame.

[0011] Furthermore, the detection device also includes a push-out electric cylinder and a detection probe fixedly mounted on the detection ramp, and a push plate is fixedly mounted on the top of the detection probe, and the push plate slides in the groove.

[0013] Furthermore, an inner rotating wheel is fixedly mounted on the inner transmission wheel, a shifting piece is fixedly mounted on the inner rotating wheel, and an ejection strip is slidably mounted on the detection ramp.

[0014] After the composite paper tube reaches the detection ramp, it slides into the groove along the slope of the detection ramp, and the toggle motor rotates to drive the output gear to rotate, thereby driving the outer gear, the inner transmission wheel and the inner rotating wheel to rotate. The inner transmission wheel drives the toggle roller gear and the toggle roller to rotate by toggle transmission belt. The toggle roller drives the composite paper tube in the groove to rotate through friction, and the surface depression of the composite paper tube is detected by the push-out electric cylinder. If the detection is unqualified, the push-out electric cylinder is extended, and the composite paper tube in the groove is pushed out by the push plate. If the detection is qualified, when the inner rotating wheel reaches under the ejection bar with the toggle piece, the ejection bar is lifted up by the toggle piece, and the ejection bar ejects the composite paper tube from the groove, the composite paper tube leaves the detection ramp along the slope of the detection ramp.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) the conveying device provided in the present invention can continuously convey the composite paper tube toward the docking device.

When the composite paper tube 123 is conveyed, the movable frame 201 starts to move in the direction away from the paper tube box 101, and the next composite paper tube 123 falls on the conveying roller 109. When the next composite paper tube 123 is conveyed to the end roller 120, the outer half-tooth gear 106 disengages from the driving gear 108. When the next end docking gear 122 rotates half a circle to drive the movable frame 201 to move toward the paper tube box 101, the outer half-tooth gear 106 starts to engage with the driving gear 108 again.

[0034] like Figure 5-Figure 9 As shown, the docking device also includes an outer roller 203 and four inner rollers 204 rotatably mounted on the mobile frame 201, the outer roller 203 and the four inner rollers 204 are wrapped with a connecting transmission belt 206, a dynamic docking gear 205 is fixedly mounted on the outer roller 203, a rear transmission column 207 and a front docking wheel 209 are rotatably mounted on the mobile frame 201, and a transmission belt 208 is wrapped around the rear transmission column 207 and the front docking wheel 209.

[0035] like Figure 5-Figure 9As shown, four toggle gears 210 are rotatably installed on the mobile frame 201, and a toggle half-column 211 is fixedly installed on the toggle gear 210. Four striking hammers 212 are slidably installed on the mobile frame 201. A striking spring 213 is arranged between the striking hammer 212 and the mobile frame 201.

The striking hammer 212 performs a compression test on the composite paper tube 123, and then moves the half column 211 to continue rotating, and pushes the striking hammer 212 to slide along the moving frame 201 by moving the arc surface 214. When the striking spring 213 is compressed to the tightest, the inner toothless gear 107 begins to engage with the rotating rod gear 112 again, and the moving frame 201 is driven away from the paper tube box 101 through the long rotating rod 114.

[0040] After the composite paper tube 123 reaches the detection ramp 301, it slides along the slope of the detection ramp 301 into the groove 302, and the toggle motor 306 rotates to drive the output gear 307 to rotate, thereby driving the outer gear 308, the inner transmission wheel 310 and the inner rotating wheel 311 to rotate, and the inner transmission wheel 310 drives the rolling gear 315 and the toggle roller 314 to rotate by toggling the transmission belt 309, and the toggle roller 314 drives the composite paper tube 123 in the groove 302 to rotate by friction, and the composite paper tube 123 in the groove 302 is rotated by the push-out electric cylinder 30 3. The surface depression of the composite paper tube 123 is detected. If the detection is unqualified, the electric cylinder 303 is extended, and the composite paper tube 123 in the groove 302 is pushed out by the push plate 304. If the detection is qualified, when the inner rotating wheel 311 brings the toggle piece 312 to the bottom of the ejection bar 313, the ejection bar 313 is lifted by the toggle piece 312, and the ejection bar 313 ejects the composite paper tube 123 from the groove 302, and the composite paper tube 123 leaves the detection ramp 301 along the slope of the detection ramp 301.

[0041] The working principle of the composite paper tube compression test device disclosed in the present invention is as follows: the conveying motor 102 rotates to drive the motor gear 103 to rotate, and the upper transmission wheel 105, the outer half-tooth gear 106 and the inner missing-tooth gear 107 are driven to rotate through the conveying belt 104, and the outer half-tooth gear 106 rotates to drive the driving gear 108 and the driving roller 119 to rotate intermittently, and the driving roller 119 drives the transmission gear 110 to rotate, and the transfer roller 118, the end roller 120 and all the conveying rollers 109 are driven to rotate through the transmission belt 111, so as to move the composite paper tube 123 at the bottom of the paper tube box 101 toward the moving frame. 201, while the end roller 120 rotates through the end gear 121 to drive the end docking gear 122 to rotate, the transfer roller 118 drives the inner docking gear 117 and the outer docking gear 116 to rotate through the transfer gear 115, the inner toothless gear 107 rotates to drive the rotating rod gear 112 to rotate, thereby driving the long rotating rod 114 to rotate through the fixed rotating rod 113, thereby driving the mobile frame 201 to move back and forth through the roller 202, the inner toothless gear 107 meshes with the rotating rod gear 112 each time, driving the rotating rod gear 112 to rotate half a circle, when the long rotating rod 114 drives the mobile frame 2 When 01 is close to the paper tube box 101, the end docking gear 122 is meshed with the dynamic docking gear 205, and the outer docking gear 116 is meshed with the front docking wheel 209. At this time, the inner toothless gear 107 is disengaged from the rotating rod gear 112, and the end docking gear 122 rotates to drive the dynamic docking gear 205 to rotate, and the outer docking gear 116 rotates to drive the front docking wheel 209 to rotate, and the dynamic docking gear 205 rotates to drive the outer roller 203 to rotate, and drives all the inner rollers 204 to rotate through the connecting transmission belt 206, through the conveying roller 109, the end roller 120, the transfer roller 118, the outer roller 20 3 and the rotation of the inner roller 204 convey the composite paper tube 123 to the inner roller 204. After the composite paper tube 123 is conveyed, the movable frame 201 starts to move in the direction away from the paper tube box 101, and the next composite paper tube 123 falls on the conveying roller 109. When the next composite paper tube 123 is conveyed to the end roller 120, the outer half-tooth gear 106 is disengaged from the driving gear 108. When the next end docking gear 122 rotates half a circle to drive the movable frame 201 to move toward the paper tube box 101, the outer half-tooth gear 106 starts to mesh with the driving gear 108 again.When the moving frame 201 moves to the side of the paper tube box 101, the end docking gear 122 drives the dynamic docking gear 205 to rotate, the outer docking gear 116 drives the front docking wheel 209 to rotate, and the rotation of the front docking wheel 209 drives the toggle gear 210 and the toggle half column 211 to rotate. At this time, the composite paper tube 123 has reached the outer roller 203 and the four inner rollers 204. In the initial state, the striking spring 213 is in a compressed state. As the toggle gear 210 and the toggle half column 211 rotate, the toggle half column 211 is separated from the toggle arc surface 214, and the striking spring 213 rebounds, driving the striking hammer 212 to pop out. The striking hammer 212 performs a compression test on the composite paper tube 123, and then moves the half column 211 to continue rotating, and pushes the striking hammer 212 to slide along the moving frame 201 by moving the arc surface 214. When the striking spring 213 is compressed to the tightest, the inner toothless gear 107 begins to engage with the rotating rod gear 112 again, and the moving frame 201 is driven away from the paper tube box 101 through the long rotating rod 114. When the moving frame 201 reaches the farthest point, the inner toothless gear 107 disengages from the rotating rod gear 112, and the composite paper tube 123 falls onto the tube outlet slope 215 due to gravity, and finally falls onto the detection slope frame 301. After the composite paper tube 123 reaches the detection ramp 301, it slides along the slope of the detection ramp 301 into the groove 302, and the toggle motor 306 rotates to drive the output gear 307 to rotate, thereby driving the outer gear 308, the inner transmission wheel 310 and the inner rotating wheel 311 to rotate, and the inner transmission wheel 310 drives the rolling gear 315 and the toggle roller 314 to rotate by toggling the transmission belt 309, and the toggle roller 314 drives the composite paper tube 123 in the groove 302 to rotate by friction, and the composite paper tube 123 in the groove 302 is rotated by the push-out electric cylinder 30 3. The surface depression of the composite paper tube 123 is detected. If the detection is unqualified, the electric cylinder 303 is extended, and the composite paper tube 123 in the groove 302 is pushed out by the push plate 304. If the detection is qualified, when the inner rotating wheel 311 brings the toggle piece 312 to the bottom of the ejection bar 313, the ejection bar 313 is lifted by the toggle piece 312, and the ejection bar 313 ejects the composite paper tube 123 from the groove 302, and the composite paper tube 123 leaves the detection ramp 301 along the slope of the detection ramp 301.
