[0026] The utility model can realize automatic waste edge removal and stacking of packaging paper shells. The waste edge of the packaging paper shells can be automatically removed by the cooperation of the waste removal needle 13 in the lower needle roller 12 and the needle hole 14 of the upper hole roller 11. The front spacing adjustment component 21 and the rear spacing adjustment component 22 realize the spacing adjustment of the packaging paper shells on the roller conveyor belt 23 through different operating speeds. The operating speed of the front spacing adjustment component 21 is greater than the operating speed of the rear spacing adjustment component 22, so that the spacing between the packaging paper shells is increased. At the same time, it cooperates with the compaction component 6 and the first conveying component 3 to enable the packaging paper shells to be arranged in a fish scale shape on the surface of the first conveying component 3. The left-aligned cardboard 51, the right-aligned cardboard 54 and the rear baffle 57 of the stacking component 5 cooperate to realize that the packaging paper shells can be automatically stacked on the surface of the fourth belt 81 of the lifting and conveying component 8. The lifting and conveying component 8 can convey the stacked packaging paper shells outward through the fourth belt 81, which is convenient for operators to take.

[0027] As a preferred embodiment of the present invention, Figure 1 , Figure 4 and Figure 5As shown, the lower needle roller 12 is provided with a radially extending installation cavity 121, and a rotating clamping structure 15 is provided in the installation cavity 121. The rotating clamping structure 15 includes a spring 153 arranged at the bottom of the installation cavity 121, and a vertical sliding channel 151 and a rotating sliding channel 152 arranged on the inner side wall of the installation cavity 121 and connected to each other. The bottom of the waste cleaning needle 13 is radially symmetrically provided with a rotating clamping block 133 that can slide with the rotating clamping structure 15.

[0028] The installation cavity 121 of the lower needle roller 12 is used to install the waste cleaning needle 13. The rotating clamping structure 15 can facilitate the replacement and installation of the waste cleaning needle 13. The waste cleaning needle 13 is provided with an outer cylinder 131, a sliding inner cylinder 135 and a needle 137. The sliding inner cylinder 135 is arranged inside the outer cylinder 131 and can slide within the outer cylinder 131. The needle 137 is coaxially arranged inside the sliding inner cylinder 135. One end of the needle 137 axially penetrates the sliding inner cylinder 135 and is connected to the outer cylinder 131. The bottom inner side of the cylinder 131 is fixedly connected, and the other end is placed outside the outer cylinder 131. The outer cylinder 131 and the bottom outer wall of the sliding inner cylinder 135 are installed with a snap ring 136. The snap ring 136 can slide within the sliding cavity 132 of the outer cylinder 131 to prevent the sliding inner cylinder 135 from sliding outward and separating from the outer cylinder 131 when pushing the waste edge. The outer wall at the top of the outer cylinder 131 is connected with a twist ring 134, which can facilitate the operator to take the waste cleaning needle 13 during installation and replacement.

[0029] Figure 5 The schematic diagram is a structural diagram in which the rotary clamping structure 15 is intercepted in the form of a cylinder. When the waste cleaning needle 13 needs to be installed, the operator holds the waste cleaning needle 13 by tightening the ring 134, and then the rotary clamping block 133 of the waste cleaning needle 13 is respectively opposite to the vertical sliding channel 151 of the rotary clamping structure 15, so that the rotary clamping block 133 enters the vertical sliding channel 151 and slides downward, so that the rotary clamping block 133 reaches the bottom of the vertical sliding channel 151 and squeezes the spring 153, and then the user drives the waste cleaning needle 13 to rotate 45° clockwise by tightening the ring 134, so that the rotary clamping block 133 slides in the rotary sliding channel 152, and the rotary clamping block 133 rotates 45° clockwise, and then the user's hand is separated from the waste cleaning needle 13, the squeezing of the spring 153 disappears and rebounds, so that the position of the rotary clamping block 133 in the rotary sliding channel 152 is fixed, thereby completing the installation of the waste cleaning needle 13 in the lower needle roller 12.

[0030] The waste edge removal component 1 is driven by the first gear 16, the second gear 17 and the first chain 18. One end of the rotating shaft of the upper hole roller 11 is connected to the first gear 16, and one end of the rotating shaft of the lower needle roller 12 is connected to the second gear 17. The first gear 16 and the second gear 17 are connected to each other through the first chain 18. When power is connected, the upper hole roller 11 or the lower needle roller 12 can be selected as the rotating roller, and its rotating shaft can be connected to the corresponding driving motor to realize power transmission.

[0031] When the waste edge removing component 1 is working, the die-cut packaging paper shell is conveyed by the transition conveyor belt 19 to between the upper hole roller 11 and the lower needle roller 12, and the upper hole roller 11 and the lower needle roller 12 rotate clockwise. During the rotation, the sliding inner cylinder 135 of the waste removal needle 13 is pulled outward due to the centrifugal force, and the needle 137 is stored inside it. The waste removal needle 13 rotates with the lower needle roller 12 and contacts the waste edge of the packaging paper shell during the rotation. The upper hole roller 11 is close to the waste removal needle 13, and the upper hole roller 11 pushes the sliding inner cylinder 135 back to the outer cylinder 131 and causes the needle 137 to be stored inside. The needle 137 is exposed. When the needle 137 is in a vertical upward state, the needle 137 penetrates the waste edge and penetrates into the needle hole 14 corresponding to the upper hole roller 11. As the upper hole roller 11 and the lower needle roller 12 continue to rotate, the needle 137 gradually turns to a vertical downward state. In this process, the needle 137 is separated from the needle hole 14 and takes the waste edge away from the packaging paper shell. The sliding inner cylinder 135 is separated from the outer cylinder 131 due to the centrifugal force, and the waste edge on the needle 137 is pushed off and falls into the collecting tank 20 for collection, thereby completing the waste edge removal process of the packaging paper shell.

[0032] As another preferred embodiment of the present invention, Figure 1 and Figure 6 As shown, the front spacing adjustment component 21 and the rear spacing adjustment component 22 have the same structure and are both provided with a first mounting block 25, a second mounting block 26, a third telescopic electric cylinder 27, a bracket 24 and a first belt 29. The cylinder end of the third telescopic electric cylinder 27 is connected to the first mounting block 25, and the telescopic rod end of the third telescopic electric cylinder 27 is connected to the second mounting block 26. The first mounting block 25 is provided with a slide groove 255 inside, and the second mounting block 26 is provided with a slider 264 that can slide with the slide groove 255. The first mounting block 25 is connected to the first transmission roller 251 and the third transmission roller 25 through the bracket 24, respectively. 2, the second mounting block 26 is connected to the second transmission roller 261 through the bracket 24, the first mounting block 25 is provided with a first telescopic electric cylinder 254 on the left side of the third telescopic electric cylinder 27, the first telescopic electric cylinder 254 is connected to the first lifting roller 253, the second mounting block 26 is provided with a second telescopic electric cylinder 263 on the right side of the third telescopic electric cylinder 27, the second telescopic electric cylinder 263 is connected to the second lifting roller 262, the first transmission roller 251, the third transmission roller 252, the second transmission roller 261, the first lifting roller 253 and the second lifting roller 262 are connected by a first belt 29.

[0033] The front spacing adjustment component 21 and the rear spacing adjustment component 22 can adjust the distance between the first belt 29 and the surface of the roller conveyor belt 23 according to the thickness of the packaging paper shell, so that the first belts 29 of the front spacing adjustment component 21 and the rear spacing adjustment component 22 can respectively drive the packaging paper shell to move on the surface of the roller conveyor belt 23. The running speed of the first belt 29 of the front spacing adjustment component 21 is greater than the running speed of the first belt 29 of the rear spacing adjustment component 22, so that the distance between the packaging paper shell on the surface of the roller conveyor belt 23 is pulled apart, thereby increasing the spacing. The roller conveyor belt 23 is composed of a plurality of parallel arranged conveying rollers 231 and is a non-powered conveyor belt.

[0034] When it is necessary to reduce the distance between the first belt 29 and the surface of the roller conveyor belt 23, first the telescopic rod of the third telescopic electric cylinder 27 is slowly retracted, so that the second mounting block 26 slowly approaches the first mounting block 25. At this time, the first belt 29 becomes loose, and then the telescopic rod of the first telescopic electric cylinder 254 is extended and drives the first lifting roller 253 to descend, and the second telescopic electric cylinder 263 drives the second lifting roller 262 to descend, so that the first belt 29 is tightened again, thereby reducing the distance between the first belt 29 and the surface of the roller conveyor belt 23.

[0035] As another preferred embodiment of the present invention, Figure 1 and Figure 7 As shown, the compaction assembly 6 is provided with a fixed rod 61, a connecting rod 65 and a compaction roller 67, the two ends of the connecting rod 65 are respectively connected with a sleeve 66 and a sliding hoop 62, the connecting rod 65 is connected to the compaction roller 67 through the sleeve 66, and the connecting rod 65 is connected to the connecting rod 65 through the sliding hoop 62.

[0036] The first connecting shaft 68 of the compaction roller 67 is movably sleeved inside the sleeve 66. When the compaction roller 67 rotates, it can drive the first connecting shaft 68 to rotate in the sleeve 66. The fixed rod 61 is movably sleeved in the sliding hoop 62. The sliding hoop 62 slides horizontally on the fixed rod 61. The sliding hoop 62 drives the compaction roller 67 to move in the same direction through the connecting rod 65, thereby realizing the adjustment of the position of the compaction roller 67 above the second belt 31 of the first conveying assembly 3. The sliding hoop 62 is fixed to the surface of the fixed rod 61 by the first bolt 63 and the first fastening nut 64.

[0037] The compaction component 6 and the first conveying component 3 work together to realize that the packaging paper shells with waste edges removed are arranged in a fish-scale shape on the surface of the second belt 31 of the first conveying component 3. The first conveying component 3 includes a first conveying roller 32 and a first driven roller 34 arranged in parallel, a second belt 31 for transmission connection between the first conveying roller 32 and the first driven roller 34, and a first motor 28 transmission connected to the first conveying roller 32. The first motor 28 drives the first conveying roller 32 to rotate, and the rotation of the first conveying roller 32 drives the second belt 31 to rotate, thereby realizing the operation of the first conveying component 3.

[0038] The packaging paper shell increases its spacing through the front spacing adjustment component 21 and the rear spacing adjustment component 22, and is conveyed by the roller conveyor belt 23 at the same time, and is conveyed to the end of the roller conveyor belt 23. Then, under the action of inertia, the end of the roller conveyor belt 23 moves toward the second belt 31 of the first conveying component 3, and falls on the surface of the second belt 31 under the compacting roller 67. Since the second belt 31 is also in a rotating state, the rear packaging paper shell partially overlaps the surface of the previous packaging paper shell, so that the packaging paper shell is arranged in a fish scale shape on the surface of the second belt 31. The compacting roller 67 can be used to slightly compress the packaging paper shell to make the arrangement of the packaging paper shell more compact. At the same time, the downward pressure of the compacting roller 67 can timely fix the position of the packaging paper shell on the surface of the second belt 31 to prevent the packaging paper shell from shifting or tipping over during the arrangement process.

[0041] The fixed adjustment component 59 can realize the adjustment of the position of the rear baffle 57 in the paper aligning station 50. The fixed plate 594 is set in the through groove 593 of the fixed block 592. The second bolt 596 penetrates the fixed block 592 and is connected to the fixed block 592. The mounting plate 591 is horizontally mounted on the frame 9 and connected to the frame 9. The fixed block 592 is mounted on the upper surface of the mounting plate 591.

After completing the adjustment of the position of the rear baffle 57 in the paper aligning station 50, the second bolt 596 is pressed down to make the second bolt 596 drive the fixing plate 594 to move downward, so that the fixing teeth 595 on the lower surface of the fixing plate 594 are engaged with the tooth groove 581 of the adjusting cross bar 58 again, so that the position of the adjusting cross bar 58 in the through groove 593 is fixed, thereby fixing the position of the rear baffle 57 in the paper aligning station 50.

[0042] During the stacking operation, the packaging paper shell enters the paper aligning station 50 from the discharge end of the second conveying assembly 4, and falls on the surface of the fourth belt 81 of the lifting conveying assembly 8 under the blocking effect of the rear baffle 57. Then, the fourth telescopic electric cylinder 53 drives the left paper aligning paperboard 51 to make a reciprocating motion close to and away from the rear baffle 57 on the left side of the rear baffle 57 through the left paper aligning cross bar 52. The fifth telescopic electric cylinder 56 drives the right paper aligning paperboard 54 to make the same reciprocating motion through the right paper aligning cross bar 55. The movement pattern of the right paper aligning paperboard 54 and the left paper aligning paperboard 51 is to approach the rear baffle 57 at the same time, and then move away from the rear baffle 57 at the same time, so as to stack the packaging paper shell. The paper shells are stacked neatly on the surface of the fourth belt 81. As the stacking height of the packaging paper shells increases, the telescopic rod of the seventh telescopic electric cylinder 85 retracts, thereby driving the fourth belt 81 to slowly descend, so that the packaging paper shells in the paper aligning station 50 are maintained at a suitable stack height. After the packaging paper shells are stacked in the paper aligning station 50, the seventh telescopic electric cylinder 85 continues to drive the fourth belt 81 to descend, so that the stacked packaging paper shells are separated from the paper aligning station 50, and then the fourth motor 83 drives the third conveying roller 82 to rotate, and the third conveying roller 82 drives the fourth belt 81 to move, thereby transporting the stacked packaging paper shells out from under the paper aligning station 50.

[0043] As another preferred embodiment of the present invention, Figure 1 and Figure 8 As shown, the first paper lifting assembly 71 and the second paper lifting assembly 72 have the same structure and are both provided with a paper lifting board 73, a support rod 74, a second connecting shaft 75 and a sixth telescopic electric cylinder 77. The support rod 74 is arranged at both ends of the paper lifting board 73, and the angle between the support rod 74 and the paper lifting board 73 is an obtuse angle. A third connecting shaft 79 is provided on the top of the support rod 74 close to the frame 9. The third connecting shaft 79 is provided with a fixedly connected first connecting seat 76. The first connecting seat 76 is fixedly connected to the telescopic rod of the sixth telescopic electric cylinder 77. A fixedly connected second connecting shaft 75 is provided at the connection between the support rod 74 and the paper lifting board 73.

[0044] When it is necessary to inspect the packaging paper shell on the second belt 31 of the first conveying component 3 and the packaging paper shell on the third belt 41 of the second conveying component 4, the corresponding paper lifting component 7 can be operated, and the first conveying component 3 and the second conveying component 4 should be stopped accordingly. The second conveying component 4 includes a second conveying roller 42 and a second driven roller 44 arranged in parallel, a third belt 41 for transmission connection between the second conveying roller 42 and the second driven roller 44, and a third motor 43 transmission connected to the second conveying roller 42.

[0045] The first paper lifting assembly 71 is arranged at the discharge end of the first conveying assembly 3, and the second paper lifting assembly 72 is arranged at the discharge end of the second conveying assembly 4. The second belt 31 of the first conveying assembly 3 is located between the two support rods 74 of the first paper lifting assembly 71, and the third belt 41 of the second conveying assembly 4 is located between the two support rods 74 of the second paper lifting assembly 72. The first paper lifting assembly 71 and the second paper lifting assembly 72 are used to prevent the packaging paper shell from continuing to move forward. The support rod 74 and the lifting paper board 73 are an integrated structure, and one end of the second connecting shaft 75 is fixedly connected to the connection between the support rod 74 and the lifting paper board 73, and the other end is movably connected to the frame 9 and can rotate in the frame 9. When it is necessary to prevent the packaging paper shell from continuing to be conveyed forward, the telescopic rod of the sixth telescopic electric cylinder 77 is extended, pushing and pushing the bracket 24 and driving the second connecting shaft 75 to rotate, so that the lifting paper board 73 is lifted upward, thereby preventing the packaging paper shell from continuing to move forward.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
