[0018] A method for using a plastic packaging barrel lifting and positioning device comprises the following steps:

[0019] S1. The input conveyor belt is connected to the conveyor belt of the plastic packaging barrel to be transported and palletized, and the packaging barrel is input into the lifting shell along the input conveyor belt;

[0020] S2, the driving motor drives the output main shaft to rotate, and drives the rotating driving claw to drive the driven rotating disk to rotate and finally drives the cam housing to rotate. If the rotating driving claw contacts the rotation limiting protrusion in the extended state during the rotation, it will be pressed down and tilted, no longer contacting the driven rotating disk, the rotation stops and the cam reset spring drives the cam housing to reset. When the output main shaft rotates, the active dial drives the driven groove wheel and the magnetic suction column to rotate through the action of the externally connected input gear, transmission idler gear and driven gear. Each time the output main shaft drives the cam housing to realize an up and down cycle, the driven groove wheel rotates sixty degrees in turn to absorb the rotation limiting protrusion back so that it no longer contacts the rotating driving claw. When the rotating driving claw rotates next time, it will drive the cam housing to rotate a greater angle. An Archimedean spiral cam groove is provided in the cam housing. The characteristic that the rotation angle is proportional to the radius is used to achieve the effect of increasing the vertical driven rod rising height in proportion to the rotation angle;

[0021] S3, the vertical follower rod realizes vertical movement by engaging the cam groove through the bottom cam contact wheel, and drives the lifting connection frame to lift and press down the lifting shell when the vertical follower rod rises and falls, and produces a delayed pause effect when lifting and pressing down the lifting shell through the effect of the delay control groove, providing time for the plastic bucket to enter the lifting shell during the pause time at the bottom, and providing time for the plastic bucket to be pushed out during the pause time at the top;

[0022] S4. During the rotation of the driven gear, the uniform rotation block on the surface continuously pushes the circulating moving block to move. The circulating moving block is clamped in the circulating path groove by the path clamping block and moves along a fixed path. When the circulating moving block is at the top of the circulating path groove, it is clamped by the top clamping block and cannot retreat. After the uniform rotation block is moved six times, it is at the bottom and is no longer clamped by the top clamping block. It retreats quickly under the action of the rack reset spring, and in the process of retreating, the meshing rack groove opened on the side is used to drive the meshing output wheel to rotate, and the meshing output wheel drives the input rotating column to rotate, and through The transmission action of the input belt and the output belt drives the stacking rotating column and the reset rotating column to rotate. When the stacking rotating column rotates, it drives the stacking box to rotate, and the stacking box that has been stacked is rotated to the other side, and the internally controlled stacking box is rotated to the lifting and pushing mechanism. The reset cam, reset follower rod and follower rod reset spring on the reset rotating column drive surface work, driving the magnetic attraction ring to reciprocate for a distance, and utilizing the magnetic attraction action of the magnetic attraction ring and the rotation limiting protrusion to suck out all the rotation limiting protrusions except the top, and reset to the extended state to block the rotation driving claw again.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In the present invention, by setting up the height adjustment mechanism and the gradual lifting mechanism, the Archimedean spiral cam groove is utilized to realize the mutual conversion of the rotation angle and the rising height, and each rotation will make the next rotation more angle, so that the subsequent lifting and pushing mechanism can lift more height each time, so that the incoming plastic barrels can be placed on the previous plastic barrels in turn to achieve the stacking effect. The entire device and the entire process are automated through the transmission between the motor and the various components, which reduces manual intervention and improves production efficiency.

[0025] In the present invention, the lifting and ejecting mechanism is provided to lift the incoming plastic barrel, and a pause time is provided before and after the lifting and lowering to allow the plastic packaging barrel to enter and exit. The automated operation process ensures that each plastic barrel is handled in a consistent manner, thereby improving the quality and consistency of the final product.

[0026] In the present invention, through the arrangement of the power storage circulation mechanism and the output reset mechanism, the rotation of the successive lifting mechanism is stored in the spring and released once after six cycles, and is used to drive the subsequent output reset mechanism to restore the entire device. The lifting and pushing out mechanism is opened again from a low position to lift and push out the plastic barrel, thereby realizing continuous lifting and positioning of the plastic packaging barrel, which is suitable for large-scale production needs.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 11The present invention provides a technical solution: a plastic packaging barrel lifting and positioning device, comprising a device shell 1, an input conveyor belt 11 is fixedly connected to the outer surface of the device shell 1, a driving motor 12 is fixedly connected to the outer surface of the device shell 1, an output spindle 13 is fixedly connected to the output end of the driving motor 12, an internal installation shell 14 is fixedly connected to the inner surface of the device shell 1, a stacking box 2 is slidably connected to the top surface of the device shell 1, a connecting beam 21 is fixedly connected to the bottom surface of the stacking box 2, a height adjustment mechanism 3 is arranged on the outer surface of the internal installation shell 14, a successive lifting mechanism 4 is arranged on the outer surface of the output spindle 13, a lifting and pushing mechanism 5 is arranged on the top surface of the internal installation shell 14, and a storage The force circulation mechanism 6, the inner surface of the device shell 1 is provided with an output reset mechanism 7. During use, the device shell 1 is used to install and protect internal components. The input conveyor belt 11 is connected to the conveyor belt of the plastic packaging barrel required for transportation and palletizing. The packaging barrel is input to the lifting and pushing mechanism 5 along the input conveyor belt 11, and is gradually raised along the height adjustment mechanism 3 and the gradual raising mechanism 4, and the plastic barrel is input into the stacking box 2. The stacking box 2 can rotate with the connecting beam 21, and the stacking box 2 after the stacking is completed is rotated to the other side, and the internally controlled stacking box 2 is rotated to the lifting and pushing mechanism 5. The entire device is controlled by the external drive motor 12 to drive the internal output spindle 13 to work, and the internal installation shell 14 is used for the internal components to pass the installation position;

[0041] The output spindle 13 penetrates the inner surface of the device housing 1, and the output spindle 13 is rotatably connected to the inner wall of the device housing 1. The internal working part of the entire device is driven by the external drive motor 12 to drive the internal output spindle 13, and all mechanisms are linked and work synchronously.

[0042] The height adjustment mechanism 3 includes a convex mounting plate 31, which is fixedly connected to the outer surface of the internal mounting shell 14, a convex sliding cylinder 311 is fixedly connected to the outer surface of the convex mounting plate 31, and a rotation limiting convex block 312 is slidably connected to the inner surface of the convex sliding cylinder 311, an active rotating disk 32 is fixedly connected to one end of the output spindle 13, a pawl return spring 321 is fixedly connected to the outer surface of the active rotating disk 32, a rotating driving pawl 322 is rotatably connected to the outer surface of the active rotating disk 32, a driven rotating disk 33 is slidably connected to one end of the active rotating disk 32, an engaging ratchet 331 is provided on the outer surface of the driven rotating disk 33, and an engaging ratchet 331 is fixedly connected to one end of the driven rotating disk 33 The outer surface of the driven rotating shaft 34 is fixedly connected with a cam housing 35, and a cam groove 351 is formed on the inner surface of the cam housing 35. A cam return spring 36 is sleeved on the outer surface of the driven rotating shaft 34. Through the setting of the height adjustment mechanism 3, during use, the output spindle 13 first drives the active rotating disk 32 and the rotating driving claw 322 on the surface to rotate. Due to the restraining effect of the ratchet return spring 321, the rotating driving claw 322 will continue to stick to the surface of the meshing ratchet 331 on the driven rotating disk 33. In this way, there is no direct connection between the active rotating disk 32 and the driven rotating disk 33, but the rotating driving claw 322 can drive the driven rotating disk 33 to rotate. The convex mounting plate 31 is installed on the protrusion mounting plate The plurality of groups of protrusion sliding cylinders 311 and rotation limiting protrusions 312 are equipped. The rotation limiting protrusions 312 can be extended or retracted into the protrusion sliding cylinder 311 by sliding. When extended, the rotation driving claw 322 will contact and press it up. At this time, the rotation driving claw 322 does not contact the groove of the meshing ratchet 331. After the rotation driving claw 322 passes over the rotation limiting protrusion 312, it will be reset again due to the restraining effect of the ratchet reset spring 321. However, at this time, the rotation driving claw 322 is at the arc surface on the meshing ratchet 331 and will not drive the driven rotating disk 33 to rotate. In this way, when the active rotating disk 32 is allowed to rotate, the rotation angle of the driven rotating disk 33 can be controlled by changing the number of extended rotation limiting protrusions 312. The driven rotating disk 33 drives the cam housing 35 to rotate through the driven rotating shaft 34. A cam reset spring 36 is installed on one side of the cam housing 35. When the rotating driving claw 322 pushes the driven rotating disk 33 to rotate, the cam reset spring 36 is twisted. After the rotating driving claw 322 is released, it no longer constrains the driven rotating disk 33. The cam reset spring 36 drives the cam housing 35 to reset. An Archimedean spiral cam groove 351 is provided in the cam housing 35. The cam groove 351 contacts the cam contact wheel 521 to drive the vertical driven rod 52 to move vertically. By utilizing the effect that the rotation angle of the Archimedean spiral is proportional to the radius, the rising height of the vertical driven rod 52 can be increased proportionally by proportionally increasing the rotation angle of the cam housing 35.

[0043] The number of the protrusion sliding cylinders 311 is six, and the six protrusion sliding cylinders 311 are distributed in a ring around the protrusion mounting plate 31. The rotation limiting protrusions 312 are made of stainless steel except for the top one which is made of plastic. The output main shaft 13 passes through the protrusion mounting plate 31. The two ends of the pawl reset spring 321 are respectively fixedly connected to the active rotating disk 32 and the rotating driving pawl 322. The meshing ratchet 331 is meshed with the rotating driving pawl 322. The number of the cam housing 35 is two. The cam groove 351 is in the shape of an Archimedean spiral. The driven shaft 34 is rotatably connected to the outer surface of the internal mounting shell 14, and the two ends of the cam return spring 36 are fixedly connected to the cam shell 35 and the internal mounting shell 14 respectively. By adjusting the six protrusion sliding cylinders 311 in sequence, the cam shell 35 has six rotatable angles, each time rotating up to sixty degrees. The topmost rotation limiting protrusion 312 is manually controlled and not affected by magnetic attraction. Then the cam shell 35 rotates at least sixty degrees, which is the minimum rising height of the vertical follower rod 52. The symmetrical cam shell 35 disperses the force and cooperates with the weight on both sides.

[0044] The step-by-step lifting mechanism 4 includes an input gear 41, which is fixedly connected to the outer surface of the output main shaft 13, and the outer surface of the input gear 41 is meshed with a transmission idler wheel 411, and the outer surface of the transmission idler wheel 411 is rotatably connected to an idler wheel support frame 4111, and the outer surface of the transmission idler wheel 411 is meshed with a driven gear 412, and one end of the driven gear 412 is fixedly connected to a driving dial 4121, and the outer surface of the driving dial 4121 is meshed with a driven groove wheel 413, and the outer surface of the driven groove wheel 413 is fixedly connected to the outer surface of the driven groove wheel 413. The intermittent toggle arm 4131 is connected, and the outer surface of the intermittent toggle arm 4131 is fixedly connected with a magnetic column 4132, and the outer surface of the driven gear 412 is fixedly connected with a uniform speed rotation block 42, and the outer surface of the internal mounting shell 14 is fixedly connected with a groove wheel support frame 43, and the outer surface of the groove wheel support frame 43 is fixedly connected with a groove wheel mounting cylinder 431. Through the setting of the successive lifting mechanism 4, during use, the output spindle 13 drives the height adjustment mechanism 3 to work, and also drives the successive lifting mechanism 4 to work. The two machines The output main shaft 13 first drives the external fixed input gear 41 to rotate, and the input gear 41 transmits the rotation to the active dial 4121 through the action of the transmission idler 411 and the driven gear 412, and the rotation direction is the same. The active dial 4121 drives the driven groove wheel 413 to rotate during the rotation. Since the driven groove wheel 413 is installed on the groove wheel installation cylinder 431 and is not connected to the output main shaft 13, only the active dial 4121 can drive it to rotate. The active dial 4121 rotates every time. The driven groove wheel 413 rotates one-sixth of a circle, and drives the intermittent toggle arm 4131 and the magnetic column 4132 to rotate sixty degrees. The magnetic column 4132 can absorb the rotation limiting protrusion 312, so that each time the output main shaft 13 rotates one circle, one rotation limiting protrusion 312 can be sucked out on one side so that it will not affect the rotation driving claw 322. Since the height adjustment mechanism 3 and the gradual lifting mechanism 4 are both driven by the output main shaft 13, the cam housing 35 can rotate a greater angle next time after being reset each time it rotates one circle, thereby achieving a gradual lifting effect.

[0045] The idler wheel support frame 4111 is fixedly connected to the outer surface of the groove wheel support frame 43, the active dial 4121 is rotatably connected to the outer surface of the groove wheel support frame 43, the driven groove wheel 413 is rotatably connected to the outer surface of the groove wheel mounting cylinder 431, the magnetic column 4132 is magnetically connected to the rotation limiting protrusion 312, the output main shaft 13 passes through the groove wheel mounting cylinder 431, the groove wheel support frame 43 and the idler wheel support frame 4111 are used to install the transmission idler wheel 411 and the driven gear 412, and do not contact the output main shaft 13 to prevent influence, and the magnetic column 4132 slides the rotation limiting protrusion 312 in sequence through magnetic attraction to change the rotation angle.

[0046] The lifting and pushing mechanism 5 includes a driven limit frame 51, which is fixedly connected to the top surface of the internal mounting shell 14, and the inner surface of the driven limit frame 51 is slidably connected to a vertical driven rod 52, and the bottom surface of the vertical driven rod 52 is rotatably connected to a cam contact wheel 521, and the outer surface of the vertical driven rod 52 is fixedly connected to a lifting connection frame 53, and the outer surface of the lifting connection frame 53 is slidably connected to a lifting shell 54, and the outer surface of the lifting shell 54 is provided with a delay control groove 541, and one end of the lifting connection frame 53 is fixedly connected to a pushing wedge 55, and the inner surface of the lifting shell 54 is slidably connected to a pushing plate 56, and the inner surface of the device shell 1 is fixedly connected to a clamping shell 57, and the inner surface of the clamping shell 57 The surface is fixedly connected with an anti-skid support pad 571. Through the setting of the lifting and pushing mechanism 5, during use, the plastic barrels that need to be stacked are moved to the inside of the lifting shell 54 through the input conveyor belt 11. The height adjustment mechanism 3 and the gradual lifting mechanism 4 cooperate with each other, so that the cam shell 35 increases the rotation angle equidistantly each time. The vertical follower rod 52 is restricted by the follower limit frame 51 and can only move vertically. The bottom contacts the cam groove 351 in the cam shell 35 through the cam contact wheel 521. By utilizing the effect that the rotation angle of the Archimedean spiral is proportional to the radius, the lifting height of the vertical follower rod 52 can be increased proportionally by increasing the rotation angle of the cam shell 35 in geometric proportion. The vertical follower rod 52 drives the lifting connecting frame 53 to penetrate into the lifting shell. 54, the lifting shell 54 is clamped by the clamping shells 57 on both sides and the internal anti-skid support pads 571, so that the lifting shell 54 will not fall due to the influence of gravity when there is no external force, and it can only move by the lifting connecting frame 53. Since the height of the delay control groove 541 is relatively large, the lifting connecting frame 53 will not contact the top when it rises. At this time, the lifting shell 54 does not move until the lifting connecting frame 53 contacts the top of the delay control groove 541 to drive the lifting shell 54 to rise, and lift the internal plastic bucket until it is lifted to the maximum height that can be raised. At this time, the cam shell 35 is reset and reversed, pulling the cam contact wheel 521 to drive the lifting connecting frame 53 to descend. Since the lifting connecting frame 53 is in a The top of the delay control groove 541 does not contact the bottom, and only when it moves to the bottom can it drive the lifting shell 54 to descend, so that both the rise and fall have a delayed time. During the period of descent delay, the push-out wedge 55 will descend on the lifting shell 54. Since the surface is a slope with a gradually increasing size, the push-out plate 56 will be pushed out, driving the plastic bottle to be pushed into the stacking box 2. When it rises next time, the push-out wedge 55 will rise on the surface of the lifting shell 54 and no longer contact the push-out plate 56. The newly entered plastic barrel will push the push-out plate 56 into the interior, realizing a rising and pushing process, and the height of each rise will increase, so that the plastic barrel that enters later will be stacked on the previous plastic barrel, achieving the effect of stacking the plastic barrels.

[0047] There are two vertical follower rods 52, and the two vertical follower rods 52 are symmetrically distributed with the central axis of the internal mounting shell 14 as the symmetry axis. The cam contact wheel 521 is slidably connected to the inner surface of the cam groove 351, and the lifting connecting frame 53 passes through the delay control groove 541 and is slidably connected to its inner wall. Both sides of the ejection plate 56 are inclined surfaces. The clamping shell 57 is slidably connected to the outer surface of the lifting shell 54. The symmetrical vertical follower rods 52 disperse the force and cooperate with the weight on both sides. The cam contact wheel 521 passively rises and falls following the trajectory of the cam groove 351. The delay caused by the sliding of the lifting connecting frame 53 in the delay control groove 541 allows the lifting shell 54 to have an interval time before rising and falling, so that the plastic bucket can enter and exit the lifting shell 54.

[0048] The power storage circulation mechanism 6 includes a fixed base 61, which is fixedly connected to the inner surface of the device housing 1, a circulation path groove 611 is provided on the outer surface of the fixed base 61, a rack return spring 62 is fixedly connected to the outer surface of the fixed base 61, a top clamping block 63 is slidably connected to the outer surface of the fixed base 61, a circulation moving block 64 is slidably connected to the outer surface of the fixed base 61, a path clamping block 641 is fixedly connected to the outer surface of the circulation moving block 64, a top ratchet groove 642 is fixedly connected to the top surface of the circulation moving block 64, and a The meshing rack groove 643, the top surface of the top ratchet groove 642 is slidably connected with an input push arm 65, and the outer surface of the meshing rack groove 643 is meshed with a meshing output wheel 66. Through the setting of the power storage circulation mechanism 6, during use, the rotation of the driven gear 412 will drive the uniform rotation block 42 to rotate, and drive the input push arm 65 to continuously move the top ratchet groove 642 to move it in one direction. The top engaging block 63 can move up and down, and will be stuck to the top of the top ratchet groove 642 and prevent reverse movement after falling. The top ratchet groove 642 drives the circulating moving block 64 to move The path engaging block 641 on the circulating moving block 64 is stuck in the circulating path groove 611, so that the path engaging block 641 moves inside the circulating path groove 611. The circulating path groove 611 is composed of an upper and a lower section. The path engaging block 641 is at the top in the initial state. At this time, the top ratchet groove 642 is in contact with the top engaging block 63, while the meshing rack groove 643 is not in contact with the meshing output wheel 66. The path engaging block 641 moves once for each rotation of the uniform speed rotating block 42. After six times, the path engaging block 641 gradually moves to the arc of the circulating path groove 611 and moves from the upper section to the lower section. At this time, the top engaging block 63 no longer blocks the top ratchet groove 642, and the rack reset spring 62 resets to pull the circulating moving block 64 back. The lower section of the circulating path groove 611 is composed of a straight line segment and an oblique line segment. Since the path engaging block 641 is at the straight line segment of the lower section at this time, the meshing rack groove 643 contacts the meshing output wheel 66, thereby driving the meshing output wheel 66 to rotate, and the path engaging block 641 will rise again after moving to the oblique line segment, return to the initial position, and complete a cycle, so as to realize the storage of the rotation of the successive lifting mechanism 4 on the spring, and release it once after six cycles, and use it to drive the subsequent output reset mechanism 7;

[0049] The circulating path groove 611 is composed of a straight line segment at the top and an oblique line segment at the bottom, and the straight line segment and the oblique line segment are connected by an arc on one side. The two ends of the rack return spring 62 are fixedly connected to the fixed base 61 and the circulating moving block 64 respectively. The top locking block 63 is slidingly connected to the top ratchet groove 642. The path locking block 641 is slidingly connected to the inner surface of the circulating path groove 611. The input push arm 65 is rotationally connected to the outer surface of the uniform rotation block 42. When the circulating moving block 64 is in a higher position, it is affected by the top locking block 63 and can only move in one direction without contacting the meshing output wheel 66. The opposite is true when it is in the bottom position.

[0050] The output reset mechanism 7 includes an input rotating column 71, which is rotatably connected to the inner surface of the device housing 1, an input belt 711 is sleeved on the outer surface of the input rotating column 71, and the other end of the input belt 711 is sleeved on the stacking rotating column 72, and the outer surface of the stacking rotating column 72 is sleeved on the output belt 721, and the other end of the output belt 721 is sleeved on the reset rotating column 73, and the outer surface of the reset rotating column 73 is fixedly connected with a reset cam 74, and the outer surface of the reset cam 74 is slidably connected with a reset driven rod 75, and the outer surface of the reset driven rod 75 is fixedly connected with a driven rod reset spring 751, and the outer surface of the reset driven rod 75 is fixedly connected with a magnetic ring 76. Through the setting of the output reset mechanism 7, during use, when the meshing output wheel 66 rotates, it will drive the input rotating column 71 to rotate, and the rotation is transmitted to the stacking rotating column 72 through the input belt 711, and the stacking box 2 is driven to rotate half a circle through the connecting beam 21. At this time, the stacking box 2 is pushed out by the lifting mechanism 5 multiple times. The plastic barrel is lifted and pushed out. The plastic barrels have been palletized inside. The palletized box 2 is transferred to the other side, and the controlled palletized box 2 is transferred to the lifting and pushing mechanism 5 for subsequent palletizing. The palletizing rotating column 72 drives the reset rotating column 73 to rotate half a circle through the output belt 721. The reset rotating column 73 is connected to the outside of the reset rotating column 73. When rotating, the protrusion of the reset cam 74 pushes the reset follower rod 75 to move a distance, and the reset follower rod reset spring 75 is retracted after the protrusion of the reset cam 74 is retracted. 51 drives the reset driven rod 75 to reset, so that the reset driven rod 75 drives the magnetic ring 76 connected thereto to reciprocate for a distance. When the magnetic ring 76 moves, it will fit on the surface of the rotation limiting protrusion 312, adsorb the rotation limiting protrusion 312 except the top, and pull all the rotation limiting protrusions 312 back to complete the reset effect when it is recovered. The rotation driving claw 322 will still be blocked by the rotation limiting protrusion 312 when it rotates next time, so that the lifting and pushing mechanism 5 is opened again from the lower position to lift and push out the plastic bucket;

[0051] The top surface of the input rotating column 71 is fixedly connected to the meshing output wheel 66, the top surface of the stacking rotating column 72 is fixedly connected to the connecting beam 21, the stacking rotating column 72 is rotatably connected to the inner surface of the device housing 1, the reset rotating column 73 is rotatably connected to the inner surface of the internal mounting housing 14, the reset cam 74 and the reset follower rod 75 are both slidably connected to the inner surface of the internal mounting housing 14, and the two ends of the follower rod reset spring 751 are respectively fixedly connected to the reset follower rod 75 and the internal mounting housing 14, and the magnetic ring 76 is magnetically connected to the rotation limiting protrusion 312, and the input rotating column 71 receives the rotation of the meshing output wheel 66. After the successive lifting mechanism 4 is raised to the highest position, the rotation of the stacking box 2 and the reset of the height adjustment mechanism 3 are triggered. The input rotating column 71, the stacking rotating column 72 and the reset rotating column 73 are driven to rotate through the belt transmission, and multiple parts are driven to work. The cam structure formed by the reset cam 74, the reset follower rod 75 and the follower rod reset spring 751 drives the magnetic ring 76 to reciprocate once to achieve reset.

[0052] In this embodiment, Figure 1 , Figure 2 As shown, the device housing 1 is used to install and protect the internal components, the input conveyor belt 11 is connected to the conveyor belt of the plastic packaging barrels to be transported and stacked, and the packaging barrels are input to the lifting and pushing mechanism 5 along the input conveyor belt 11, and the internal installation housing 14 is used for the internal components to pass the installation position;

[0053] In this embodiment, Figure 3 As shown, the output spindle 13 penetrates the inner side of the device housing 1, and the internal working part of the entire device is driven by the external drive motor 12 to drive the internal output spindle 13, and all mechanisms are linked and work synchronously;

[0054] In this embodiment, Figure 4 As shown, the output main shaft 13 first drives the active rotating disk 32 and the rotating driving claw 322 on the surface to rotate. Due to the restraining effect of the pawl reset spring 321, the rotating driving claw 322 will continue to stick to the surface of the meshing ratchet 331 on the driven rotating disk 33, so that there is no direct connection between the active rotating disk 32 and the driven rotating disk 33, but the rotating driving claw 322 can drive the driven rotating disk 33 to rotate;

[0055] In this embodiment, Figure 5 As shown, when the rotation limiting protrusion 312 extends out, it will contact and press the rotation driving claw 322, and at this time, the rotation driving claw 322 does not contact the groove of the meshing ratchet 331;

[0056] In this embodiment, Figure 6As shown, the output main shaft 13 first drives the external fixed input gear 41 to rotate, and the input gear 41 transmits the rotation to the active dial 4121 through the action of the transmission idler 411 and the driven gear 412 in the same direction, and the active dial 4121 rotates and drives the driven groove wheel 413 to rotate;

[0057] In this embodiment, Figure 7 As shown, due to the large height dimension of the delay control slot 541, the lifting connection frame 53 will not contact the top when rising, and only when it moves to the top or bottom can it drive the lifting housing 54 to rise or fall, so that there is a delay time for both rising and falling;

[0058] In this embodiment, Figure 8 As shown, the driven gear 412 rotates, which drives the uniform speed rotating block 42 to rotate, and drives the input push arm 65 to continuously move the top ratchet groove 642 to move it in one direction;

[0059] In this embodiment, Fig. 9 As shown, the circulation path groove 611 is composed of an upper and lower section. The path engaging block 641 is at the top in the initial state. At this time, the top ratchet groove 642 is in contact with the top engaging block 63, while the meshing rack groove 643 is not in contact with the meshing output wheel 66. The path engaging block 641 moves once for each rotation of the uniform speed rotating block 42. After six times, the path engaging block 641 gradually moves to the arc of the circulation path groove 611 and moves from the upper section to the lower section. At this time, the top engaging block 63 no longer blocks the top ratchet groove 642, and the rack reset spring 62 resets to pull the circulation moving block 64 back.

[0060] In this embodiment, Fig.10 As shown, the input rotating column 71 receives the rotation of the meshing output wheel 66, and drives the input rotating column 71, the stacking rotating column 72 and the reset rotating column 73 to rotate through the belt transmission, thereby triggering the rotation of the stacking box 2 and the reset of the height adjustment mechanism 3. The cam structure formed by the reset cam 74, the reset driven rod 75 and the driven rod reset spring 751 causes the reset driven rod 75 to reciprocate for a distance;

[0061] In this embodiment, Fig.11 As shown, when the magnetic ring 76 moves, it will adhere to the surface of the rotation limiting protrusion 312, absorb the rotation limiting protrusion 312 except the top, and pull all the rotation limiting protrusions 312 back to complete the reset effect when recovered.

[0062] A method for using a plastic packaging barrel lifting and positioning device comprises the following steps:

[0063] S1. The input conveyor belt 11 is connected to the conveyor belt of the plastic packaging barrels to be transported and palletized, and the packaging barrels are input into the lifting shell 54 along the input conveyor belt 11.

[0064] S2, the driving motor 12 drives the output main shaft 13 to rotate, and drives the rotating driving claw 322 to drive the driven rotating disk 33 to rotate and finally drives the cam housing 35 to rotate. If the rotating driving claw 322 contacts the extended rotation limiting protrusion 312 during the rotation, it will be pressed down and tilted, no longer contacting the driven rotating disk 33, the rotation stops and the cam reset spring 36 drives the cam housing 35 to reset. When the output main shaft 13 rotates, the active dial 4121 is driven to shift through the externally connected input gear 41, the transmission idler gear 411 and the driven gear 412. The driven groove wheel 413 and the magnetic column 4132 rotate, and the output main shaft 13 drives the cam housing 35 to realize an up and down cycle each time. The driven groove wheel 413 rotates sixty degrees in turn to absorb the rotation limiting protrusion 312 back, so that it no longer contacts the rotating driving claw 322, and the next time the rotating driving claw 322 rotates, it will drive the cam housing 35 to rotate a greater angle. An Archimedean spiral cam groove 351 is opened in the cam housing 35. The characteristic that the rotation angle is proportional to the radius is utilized to achieve the effect of proportionally increasing the rotation angle to proportionally increase the rising height of the vertical driven rod 52.

[0065] S3. The vertical follower rod 52 realizes vertical movement by engaging the cam groove 351 through the bottom cam contact wheel 521. When the vertical follower rod 52 rises and falls, it drives the lifting connecting frame 53 to lift and press down the lifting shell 54, and through the action of the delay control groove 541, a delayed pause effect will be produced when lifting and pressing down the lifting shell 54, providing time for the plastic barrel to enter the lifting shell 54 during the pause time at the bottom, and providing time for the plastic barrel to be pushed out during the pause time at the top.

[0066] S4. During the rotation of the driven gear 412, the uniform rotation block 42 on the surface continuously pushes the circulating moving block 64 to move. The circulating moving block 64 is clamped in the circulating path groove 611 through the path clamping block 641 and moves along a fixed path. When the circulating moving block 64 is at the top of the circulating path groove 611, it is clamped by the top clamping block 63 and cannot retreat. After the uniform rotation block 42 is moved six times, it is at the bottom and is no longer clamped by the top clamping block 63. It retreats quickly under the action of the rack return spring 62, and in the process of retreating, the meshing rack groove 643 opened on the side is used to drive the meshing output wheel 66 to rotate, and the meshing output wheel 66 drives the input rotating column 71 to rotate, and through The transmission action of the input belt 711 and the output belt 721 drives the stacking rotating column 72 and the reset rotating column 73 to rotate. When the stacking rotating column 72 rotates, it will drive the stacking box 2 to rotate, rotate the stacking box 2 that has been stacked to the other side, and rotate the internally controlled stacking box 2 to the lifting and pushing mechanism 5. The reset rotating column 73 drives the reset cam 74, the reset follower rod 75 and the follower rod reset spring 751 on the surface to work, driving the magnetic attraction ring 76 to reciprocate for a distance, and utilizing the magnetic attraction action of the magnetic attraction ring 76 and the rotation limiting protrusion 312 to suck out all the rotation limiting protrusions 312 except the top, reset to the extended state and block the rotation driving claw 322 again.

When the output main shaft (13) rotates, the active dial (412) is driven by the externally connected input gear (41), the transmission idler gear (411) and the driven gear (412). 1) The driven groove wheel (413) and the magnetic column (4132) are rotated, and the output main shaft (13) drives the cam housing (35) to realize an up and down cycle each time. The driven groove wheel (413) rotates sixty degrees in sequence to suck back the rotation limiting protrusion (312), so that it no longer contacts the rotation driving claw (322). When the rotation driving claw (322) rotates next time, it drives the cam housing (35) to rotate a greater angle. An Archimedean spiral cam groove (351) is provided in the cam housing (35). By utilizing the characteristic that the rotation angle is proportional to the radius, the effect of increasing the rising height of the vertical driven rod (52) in proportion to the rotation angle is achieved; S3, the vertical follower rod (52) engages the cam groove (351) through the bottom cam contact wheel (521) to achieve vertical movement, and the vertical follower rod (52) drives the lifting connection frame (53) to lift and press down the lifting shell (54) when rising and falling, and through the action of the delay control groove (541), a delayed pause effect is generated when the lifting shell (54) is lifted and pressed down, providing time for the plastic barrel to enter the lifting shell (54) during the pause time at the bottom, and providing time for the plastic barrel to be pushed out during the pause time at the top; S4, during the rotation of the driven gear (412), the uniform rotation block (42) on the surface continuously pushes the circulating moving block (64) to move, and the circulating moving block (64) is stuck in the circulating path groove (611) through the path locking block (641) and moves along a fixed path. When the circulating moving block (64) is at the top of the circulating path groove (611), it is stuck by the top locking block (63) and cannot retreat. After the uniform rotation block (42) is moved six times, it is at the bottom and is no longer stuck by the top locking block (63) and is quickly retreated by the rack return spring (62). In the process of retreating, the meshing rack groove (643) opened on the side is used to drive the meshing output wheel (66) to rotate, and the meshing output wheel (66) drives the input rotating column (71) to rotate, and through the input belt (711) and the output belt (72 The stacking rotating column (72) and the reset rotating column (73) are driven to rotate by the transmission effect of 1, and the stacking rotating column (72) drives the stacking box (2) to rotate, and the stacking box (2) that has been stacked is rotated to the other side, and the stacking box (2) controlled inside is rotated to the lifting and pushing mechanism (5). The reset rotating column (73) drives the reset cam (74), the reset follower rod (75) and the follower rod reset spring (751) on the surface to work, and drives the magnetic attraction ring (76) to reciprocate for a distance. The magnetic attraction effect of the magnetic attraction ring (76) and the rotation limiting protrusion (312) is utilized. At this time, the magnetic attraction column (4132) is located at the top plastic rotation limiting protrusion (312), and all the rotation limiting protrusions (312) except the top are sucked out, and reset to the extended state to block the rotation driving claw (322) again.
