Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0036] Referring to Figures 1 to 4 , the embodiments of the present invention provide a packaging machine, including a feeding conveyor belt 100, a first turntable 200, a material pushing mechanism 300, a packaging paper conveying mechanism 400, a converging block 500, and a lifting mechanism 600.

[0037] Referring to Figure 2, it can be understood that the feeding conveyor belt 100 is arranged horizontally, and a plurality of chocolate pens 1000 are arranged end to end on the feeding conveyor belt 100. By rotating the feeding conveyor belt 100, the chocolate pens 1000 can be conveyed one by one.

[0038] Referring to Figure 1 and Figure 2 , it can be understood that the first turntable 200 is arranged horizontally, that is, the rotation axis of the first turntable 200 is arranged vertically, and the first turntable 200 is located on one side of the output end of the feeding conveyor belt 100. Four material grooves 210 are arranged on the upper end surface of the first turntable 200, and the four material grooves 210 are evenly distributed along the circumferential direction of the first turntable 200. The length direction of the material groove 210 is perpendicular to the radial direction of the first turntable 200, and the length of the material groove 210 is slightly greater than the length of the chocolate pen 1000. A hollow part 220 penetrating the first turntable 200 is arranged at the middle position of the bottom wall of the material groove 210. When the chocolate pen 1000 is placed in the material groove 210, both ends of the chocolate pen 1000 abut against the bottom wall of the material groove 210, and the middle position of the chocolate pen 1000 is suspended.

[0039] Of course, it can be understood that the number of the material grooves 210 is not limited to four, and can also be five, six, etc. The number of the material grooves 210 is not specifically limited here.

[0040] Referring to Figure 2 , it can be understood that the pushing mechanism 300 is arranged on the other side of the output end of the feeding conveyor belt 100. Generally speaking, the pushing mechanism 300 is provided with a pushing block 310, and the pushing block 310 can move along the width direction of the feeding conveyor belt 100, so as to push the chocolate pen 1000 at the output end of the feeding conveyor belt 100 into the material groove 210, and the structure is simple.

[0041] Referring to Figure 2, it can be understood that the wrapping paper conveying mechanism 400 is arranged on the circumferential side of the first turntable 200, and the wrapping paper conveying mechanism 400 and the feeding conveyor belt 100 are arranged at intervals along the circumferential direction of the first turntable 200, with an interval of 90°. The output end of the wrapping paper conveying mechanism 400 faces the first turntable 200, and the output end is generally higher than the first turntable 200. The wrapping paper conveying mechanism 400 includes a plurality of conveying rollers 420, and the wrapping paper is wound around the plurality of conveying rollers 420. By driving the conveying rollers 420 to rotate with a motor (not shown in the figure), the wrapping paper can be output. A cutter 410 that moves up and down is provided at the output end of the wrapping paper conveying mechanism 400. When the wrapping paper is output by a set length, the wrapping paper can be cut off by the cutter 410. When the first turntable 200 moves the chocolate pen 1000 to the output end of the wrapping paper conveying mechanism 400, the wrapping paper conveying mechanism 400 outputs a certain length of wrapping paper so that the wrapping paper covers the upper side of the chocolate pen 1000. Generally speaking, along the output direction, the length of the wrapping paper is greater than the circumference of the circumferential wall of the chocolate pen 1000; along the direction perpendicular to the output direction, the width of the wrapping paper is greater than the length of the chocolate pen 1000.

[0042] Referring to Figure 1 , it can be understood that the converging block 500 is arranged above the first turntable 200 and above the output end of the wrapping paper conveying mechanism 400. The converging block 500 is provided with a converging groove 510 that penetrates in the vertical direction, and the converging groove 510 can allow the chocolate pen 1000 to pass through.

[0043] Referring to Figure 1 , it can be understood that the lifting mechanism 600 is arranged at the output end of the wrapping paper conveying mechanism 400. The lifting mechanism 600 includes a lower clamping block 610 and an upper clamping block 620 that move in the vertical direction. The upper clamping block 620 is located above the lower clamping block 610, and in the vertical direction, the upper clamping block 620, the lower clamping block 610, and the converging block 500 are correspondingly arranged. Generally speaking, the lower clamping block 610 is located below the first turntable 200 and can pass through the hollow part 220, and the upper clamping block 620 is located above the first turntable 200. When the first turntable 200 moves the chocolate pen 1000 to the output end of the wrapping paper conveying mechanism 400 and the upper side of the chocolate pen 1000 is covered with the wrapping paper, the upper clamping block 620 and the lower clamping block 610 move towards each other and clamp the chocolate pen 1000 and the wrapping paper. Subsequently, the upper clamping block 620 and the lower clamping block 610 move upward synchronously, so that the chocolate pen 1000 and the wrapping paper pass through the converging groove 510. Under the action of the two side walls of the converging groove 510, the wrapping paper on both sides of the chocolate pen 1000 is bent downward to wrap the chocolate pen 1000, so as to package the chocolate pen 1000.

[0044] The chocolate pen 1000 on the feeding conveyor belt 100 is pushed to the material groove 210 of the first turntable 200 by the pushing mechanism 300. The first turntable 200 rotates to move the chocolate pen 1000 to the output end of the wrapping paper conveying mechanism 400. The wrapping paper conveying mechanism 400 outputs the wrapping paper and covers it on the upper side of the chocolate pen 1000. The cutter 410 intercepts a certain length of the wrapping paper. Then, the lower clamping block 610 and the upper clamping block 620 of the lifting mechanism 600 clamp the chocolate pen 1000 and the wrapping paper and convey them upward. When the chocolate pen 1000 and the wrapping paper covering its upper side pass through the converging groove 510, the groove walls on both sides of the converging groove 510 bend the wrapping paper downward, so that the wrapping paper wraps around the outer periphery of the chocolate pen 1000 to package the chocolate pen 1000. Since the first turntable 200 is provided with a plurality of material grooves 210, it can continuously package a plurality of chocolate pens 1000 in sequence, replacing manual operation, reducing the risk of the chocolate pen 1000 being broken, improving the yield rate, and having high packaging efficiency and increased production capacity.

[0045] Referring to Figure 1 , it can be understood that the distance between the two side walls of the converging groove 510 gradually decreases from bottom to top, that is, the upper end of the converging groove 510 is small and the lower end is large. When the chocolate pen 1000 and the wrapping paper covering the upper side of the chocolate pen 1000 pass through the converging groove 510 at the same time, the groove walls on both sides can gradually bend the wrapping paper on both sides of the chocolate pen 1000 and make the wrapping paper wrap around the chocolate pen 1000, avoiding the drawback that the wrapping paper is instantaneously bent to form a fold angle and affecting the appearance.

[0046] Referring to Figure 1, it can be understood that it further includes a second turntable 700 arranged in the vertical direction, that is, the center line of the second turntable 700 is arranged in the horizontal direction. The second turntable 700 is located above the converging block 500. The second turntable 700 is provided with four clamping clips 710, and the four clamping clips 710 are evenly distributed along the circumferential direction of the second turntable 700. When the upper clamping block 620 and the lower clamping block 610 clamp the chocolate pen 1000 and the wrapping paper covering the upper side of the chocolate pen 1000 and pass through the converging groove 510, the clamping clips 710 clamp the wrapping paper on both sides of the chocolate pen 1000, so that the wrapping paper keeps wrapping both sides of the chocolate pen 1000. At this time, the upper clamping block 620 and the lower clamping block 610 leave the chocolate pen 1000. Generally speaking, along the radial direction of the second turntable 700, the swing arms of the upper clamping block 620, the lower clamping block 610 and the clamping clips 710 are arranged in a staggered manner, that is, the upper clamping block 620 and the lower clamping block 610 will not interfere with the second turntable 700 to drive the clamping clips 710 to rotate. The second turntable 700 rotates, and the clamping clips 710 drive the chocolate pen 1000 and the wrapping paper to move and leave above the converging groove 510, that is, the chocolate pen 1000 and the wrapping paper move to one side of the converging block 500. Under the action of the top wall of the converging block 500, the wrapping paper on one side of the chocolate pen 1000 is folded towards the lower side of the chocolate pen 1000 to further wrap the chocolate pen 1000 and convey the chocolate pen 1000 to the next working station. Since the second turntable 700 is provided with four clamping clips 710, continuous packaging can be carried out, and the efficiency is high.

[0047] Refer to Figure 1 , it can be understood that it further includes an origami block 720, and the origami block 720 is swingably arranged on the other side of the converging block 500. When the clamping clips 710 clamp the chocolate pen 1000 and the wrapping paper, the origami block 720 swings downward, and the end of the origami block 720 folds the wrapping paper on the other side of the chocolate pen 1000 towards the lower side of the chocolate pen 1000 to further wrap the chocolate pen 1000 for complete packaging, and the structure is simple.

[0048] Refer to Figure 1It can be understood that the end pressing mechanism 800 is also provided on the peripheral side of the second rotating disk 700. Specifically, the end pressing mechanism 800 is located on the left side of the convergence block 500. The end pressing mechanism 800 includes pressing blocks 810 arranged at intervals along the center line direction of the second rotating disk 700. Generally speaking, four pressing blocks 810 are respectively provided at both ends along the center line direction of the second rotating disk 700. When the chocolate pen 1000 is conveyed to the end pressing mechanism 800, the four pressing blocks 810 at each end are evenly distributed around the chocolate pen 1000. Each pressing block 810 is connected to a swing rod 820. The swing of the swing rod 820 can move the pressing block 810 toward the end of the chocolate pen 1000, so that the wrapping paper at the end of the chocolate pen 1000 is bent and covers the end of the chocolate pen 1000, so as to press the wrapping paper at the end of the chocolate pen 1000, so that the wrapping paper completely wraps the chocolate pen 1000. The structure is simple and easy to implement.

[0049] Reference Figure 1 It can be understood that a guide plate 730 is provided between the end pressing mechanism 800 and the convergence block 500. The guide plate 730 is arc-shaped, one end of the guide plate 730 is connected to the top wall of the convergence block 500, and the other end extends to the middle position of the end pressing mechanism 800. When the material clamp 710 of the second turntable 700 drives the chocolate pen 1000 and the wrapping paper to move toward the end pressing mechanism 800, the wrapping paper on the lower side of the chocolate pen 1000 is kept wrapped around the lower side of the chocolate pen 1000 under the abutment of the guide plate 730, so as to prevent the wrapping paper from loosening and causing the chocolate to be unable to be further wrapped, thereby improving reliability.

[0050] Reference Figure 1 It can be understood that it also includes a discharge conveyor belt 900 and a lifting arm 910 located on the top of the second turntable 700, and the lifting arm 910 is arranged below the input end of the discharge conveyor belt 900. Generally speaking, in the vertical direction, the lifting arm 910 and the material clamp 710 are arranged in a staggered manner, that is, the lifting arm 910 will not interfere with the second turntable 700 driving the material clamp 710 to rotate, and a material tray 930 is arranged below the discharge conveyor belt 900. When the material clamp 710 transfers the packaged chocolate pen 1000 to the top of the second turntable 700, the lifting arm 910 moves up and receives both ends of the chocolate pen 1000. At the same time, the material clamp 710 releases the chocolate pen 1000, and the lifting arm 910 moves up further to transfer the chocolate pen 1000 to the lower side of the discharge conveyor belt 900. Relying on the friction force, the chocolate pen 1000 on the lifting arm 910 rolls to the material tray 930 under the discharge conveyor belt 900, so that the chocolate pen 1000 is output for the next operation. In this way, the chocolate pen 1000 can be output in an orderly manner without manual adjustment, which effectively improves efficiency.

[0051] Reference Figure 1 and Figure 3It can be understood that the lifting arm 910 is provided with two holding blocks 920 arranged at intervals along the center line direction of the second turntable 700. Grooves 921 are respectively arranged on the opposite sides of the holding block 920. The openings of the grooves 921 face the side of the tray 930, and the depth of the grooves 921 is less than the outer diameter of the chocolate pen 1000. When the chocolate pen 1000 is transferred upward, both ends of the chocolate pen 1000 are respectively received in the grooves 921, so as to axially limit the chocolate pen 1000 and prevent the chocolate pen 1000 from falling off during the transfer process, improving reliability. And the chocolate pen 1000 can contact the lower side of the discharge conveyor belt 900, so as to further transfer the chocolate pen 1000 to the tray 930 by relying on friction, realizing output. The structure is simple and easy to implement.

[0052] The packaging process is as follows: The pusher block 310 of the pusher mechanism 300 pushes the chocolate pen 1000 on the feeding conveyor belt 100 into the trough 210 of the first turntable 200. The first turntable 200 rotates to move the chocolate pen 1000 to the output end of the wrapping paper conveying mechanism 400. The wrapping paper conveying mechanism 400 outputs the wrapping paper and covers it on the upper side of the chocolate pen 1000. The cutter 410 intercepts a certain length of wrapping paper. Then, the lower clamp block 610 and the upper clamp block 620 of the lifting mechanism 600 clamp the chocolate pen 1000 and the wrapping paper and convey them upward. When the chocolate pen 1000 and the wrapping paper covered on the upper side pass through the converging groove 510, the groove walls on both sides of the converging groove 510 bend the wrapping paper downward, so that the wrapping paper wraps around both sides of the chocolate pen 1000. Then, the material clamp 710 clamps both sides of the chocolate pen 1000, the upper clamp block 620 and the lower clamp block 610 are released, and the folding block 720 swings towards the chocolate pen 1000, so that the wrapping paper on one side of the chocolate pen 1000 folds towards the lower side of the chocolate pen 1000. Subsequently, the second turntable 700 rotates, and drives the chocolate pen 1000 to move along the guide plate 730 through the material clamp 710. Under the action of the top wall of the converging block 500, the wrapping paper on the other side of the chocolate pen 1000 folds towards the lower side of the chocolate pen 1000, so as to wrap around the chocolate pen 1000 along the circumferential direction. When it moves to the end pressing mechanism 800, the pressing block 810 presses the wrapping paper at the end of the chocolate pen 1000 to the end of the chocolate pen 1000, so that the wrapping paper completely wraps the chocolate pen 1000, realizing guarantee. Subsequently, the second turntable 700 continues to rotate, transfers the packaged chocolate pen 1000 to the lifting arm 910. The lifting arm 910 receives the chocolate pen 1000, the material clamp 710 is released, and the lifting arm 910 drives the chocolate pen 1000 to move upward to the discharge conveyor belt 900. Relying on friction, the discharge conveyor belt 900 rolls the chocolate pen 1000 into the tray 930, realizing output. In this way, the continuous packaging of the chocolate pen 1000 is realized, without manual operation, with high efficiency, and the risk of the chocolate pen 1000 being broken can be reduced, the yield rate can be improved, and the production capacity can be increased.

[0053] Referring to Figure 4 , it can be understood that the pusher mechanism 300 includes a pusher block 310, a push rod 320, a first swing arm 330, a connecting rod 340, a second swing arm 350, a first driving motor 360 and a second driving motor 370. The first driving motor 360 is connected to the lower end of the first swing arm 330 to drive the first swing arm 330 to swing. The second driving motor 370 is connected to the left end of the second swing arm 350 to drive the second swing arm 350 to swing. The pusher block 310 is installed at the left end of the push rod 320. The middle of the push rod 320 is hinged to the upper end of the first swing arm 330. The two ends of the connecting rod 340 are respectively hinged to the right end of the push rod 320 and the right end of the second swing arm 350. It is defined that when the pusher block 310 moves to the left, it pushes the chocolate pen 1000 to the material trough 210. When pushing the chocolate pen 1000, the first driving motor 360 drives the first swing arm 330 to swing upward, so that the pusher block 310 moves to the left. At the same time, the second driving motor 370 drives the second swing arm 350 to swing upward, and drives the right end of the push rod 320 to move upward through the connecting rod 340, and the pusher block 310 moves downward until the push rod 320 is close to the horizontal state. As the first swing arm 330 further swings, the second driving motor 370 drives the second swing arm 350 to swing in the opposite direction, so that the push rod 320 remains close to the horizontal state, thereby realizing the pushing of the chocolate pen 1000. When the pusher block 310 is reset, the second driving motor 370 drives the second swing arm 350 to swing downward, so that the pusher block 310 moves upward and leaves the feeding conveyor belt 100. At the same time, the first driving motor 360 drives the first swing arm 330 to swing downward, so that the pusher block 310 moves to the right to realize the reset. Since the pusher block 310 will move upward and leave the feeding conveyor belt 100 during the reset process, at this time, the feeding conveyor belt 100 can convey the next chocolate pen 1000 to the output end without waiting for the pusher block 310 to be completely reset before conveying the next chocolate pen 1000, effectively improving the efficiency.

[0054] Referring to Figure 4 , it can be understood that a soft cushion layer 311, such as a rubber layer or a silica gel layer, etc., is provided at one end of the pusher block 310 facing the first turntable 200, so as to avoid damaging the chocolate pen 1000 during the process of the pusher block 310 pushing the chocolate pen 1000 and improve the quality of the chocolate pen 1000.

[0055] The embodiments of the present invention have been described in detail above with reference to the drawings, but the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
