DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1: A production and packaging mechanism for round display shells, such as Figure 1-Figure 2As shown, it includes a base 1, the upper left part of the base 1 is connected to a multi-stage cylinder 3 through a support frame, the multi-stage cylinder 3 is electrically connected to the external control system, the telescopic rod of the multi-stage cylinder 3 is provided with a mobile seat 2, the mobile seat 2 and the base 1 are slidably connected, and the upper right part of the base 1 is provided with a conveying mechanism 4 for conveying the packaging box, the mobile seat 2 is slidably connected to a lifting block 5, the lifting block 5 is rotatably connected to a rotating platform 6, and the rotating platform 6 has four clamps for locking round fireworks. The clamps are existing technologies and this solution is not much. To explain, a rodless cylinder 7 is fixedly connected to the top of the movable seat 2, and the rodless cylinder 7 is electrically connected to the external control system. A movable frame 8 is slidably connected to the rodless cylinder 7, and electric wheels 9 are slidably connected to the left and right sides of the lower part of the movable frame 8. The electric wheels 9 are used to transport the plastic film. A spring 10 is connected between the front and rear sides of the electric wheel 9 and the movable frame 8. Four equally spaced annular knives 11 are provided at the bottom of the movable frame 8. The annular knives 11 are used to cut the plastic film. A lifting mechanism is provided between the base 1 and the movable seat 2.

[0030] like Figure 1 As shown, the lifting mechanism includes a wire wheel 12, and the upper and lower sides of the movable seat 2 are symmetrically connected to the wire wheel 12 in a front-to-back rotation manner. A pull rope 13 is wound around the lower wire wheel 12, and the end of the pull rope 13 passes around the upper wire wheel 12. The end of the pull rope 13 is fixedly connected to the lifting block 5, and the side of the lower wire wheel 12 away from each other is fixedly connected to the gear 14, and the front and rear sides of the base 1 are slidably connected to the rack 15.

[0031] like Figure 3-Figure 4 As shown, it also includes a moving body 16, which is slidably connected to the base 1. A track is provided on the rack 15, and the track consists of two straight tracks and an oblique track. The oblique track is inclined at the bottom left and the high right. The straight track and the oblique track are connected, and the track is slidably connected to the moving body 16.

[0032] When people need to use the production and packaging mechanism of the round display shells to package the round display shells, they first clamp the four round display shells onto the rotating table 6, and the clamp inside the rotating table 6 will automatically clamp the round display shells. Then, the plastic film is wound between the two electric wheels 9, and the adhesive surface of the plastic film faces downward. The packaging box is placed on the top of the conveying mechanism 4. Then, people hold the moving frame 8 and move it to the left. The moving frame 8 moves the rack 15 upward through the oblique track, so that the rack 15 and the gear 14 are engaged. Then, the telescopic rod of the multi-stage cylinder 3 can be controlled to extend. The telescopic rod of the multi-stage cylinder 3 drives the moving seat 2 to move right. The rightward movement of the moving seat 2 will drive the rodless cylinder 7 and the moving The frame 8 and the gear 14 move to the right. Since the gear 14 and the rack 15 are meshed, the gear 14 will rotate. The rotation of the gear 14 will drive the reel 12 below to rotate the winding rope 13. The rope 13 will pull the lifting block 5 upward. The lifting block 5 moves upward and drives the rotating table 6 to move upward. The upward movement of the rotating table 6 will drive the round display shell upward. When the top of the round display shell contacts the plastic film, the plastic film will adhere to the upper end of the round display shell. The round display shell continues to move upward and drives the plastic film to move toward the position of the annular knife 11. When the annular knife 11 contacts the plastic film, the annular knife 11 will automatically cut the plastic film. In this way, the plastic film can automatically adhere to the upper end of the round display shell.

[0033] It should be noted that when the round display shell drives the plastic film upward, the plastic film is compressed and pulls the electric wheels 9 on both sides to move inward, and the spring 10 is compressed and acts as a buffer. In this way, the plastic film will not be broken by the squeezing force, and the plastic film can be wrapped around the upper end and peripheral position of the round display shell. After the plastic film is cut by the annular knife 11, the spring 10 will drive the electric wheels 9 to move away from each other and reset.

[0034] After the annular knife 11 cuts the plastic film, the rodless cylinder 7 drives the movable frame 8 to move upward, and the movable frame 8 moves forward, which drives the annular knife 11 to move forward, so that the annular knife 11 is separated from the round display shell. The purpose is to prevent the position of the annular knife 11 from affecting the 90-degree rotation of the round display shell.

[0035] In addition, it should be noted that the rodless cylinder 7 and the multi-stage cylinder 3 are both connected through an external control system. Therefore, before using the production and packaging mechanism of the round display shell, people can time the triggering time of the rodless cylinder 7. After the multi-stage cylinder 3 works for 4 seconds, the annular knife 11 cuts the plastic film, and then the rodless cylinder 7 starts to work, so that the movable frame 8 and the annular knife 11 are lifted to avoid affecting the rotation of the round display shell.

[0036] After the movable frame 8 and the annular knife 11 are lifted, the lifting block 5 will continue to drive the rotary table 6 to move upward, and the rotary table 6 will drive the round display shells to continue to move upward. When the rotary table 6 moves upward to the top, the rotary table 6 will be triggered and rotate 90 degrees clockwise. Subsequently, the movable seat 2 will continue to drive the rotary table 6 and the round display shells to move to the right, pushing the four round display shells into the packaging box. The clamp in the rotary table 6 will automatically release the round display shells. Then, the packaged round display shells will be transported to the right to the next process through the conveying mechanism 4, and the multi-stage cylinder 3 will drive the movable seat 2 and the rotary table 6 to move to the left and reset. After that, the rotary table 6 will automatically drop to the initial position. At the same time, the rodless cylinder 7 will drive the movable frame 8 to move downward and reset. The movable frame 8 drives the annular knife 11 and the electric wheel 9 to move downward. Then the electric wheel 9 will automatically rotate to work, so that the electric wheel 9 will convey the plastic film and move the new plastic film to just above the rotary table 6 so that people can pack the next batch of round display shells.

[0037] Example 2: On the basis of Example 1, it also includes a supporting member 17 symmetrically arranged in the front and rear directions. The supporting members 17 are all slidably connected to the lifting block 5. The top of the supporting member 17 and the bottom of the rotating table 6 are squeezed together. A spring 2 18 is connected between the left part of the supporting member 17 and the lifting block 5. The front and rear sides of the supporting member 17 are connected to a contact rod 19. The front and rear sides of the movable seat 2 are connected to a wedge plate 191. The wedge plate 191 and the contact rod 19 are squeezed together.

[0038] As mentioned above, when the rotating platform 6 rises to the top position, it will rotate 90 degrees clockwise, but it does not mention how to drive the rotating platform 6 to rotate 90 degrees. Therefore, this solution proposes that since the abutment 17 abuts the bottom of the rotating platform 6, the rotating platform 6 is in a straight state in the initial state, and when the rotating platform 6 moves upward, it will drive the abutment 17 and the contact rod 19 to move upward together. During the upward movement of the contact rod 19, it is always close to the flat surface of the wedge plate 191. When the contact rod 19 moves upward to the wedge surface of the wedge plate 191, the initial state is that the stretched spring 2 18 drives the abutment 17 and the contact rod 19 to move to the left. When the abutment 17 moves to the left, Slowly away from the rotating platform 6, the bottom of the rotating platform 6 loses its supporting force, so the rotating platform 6 will rotate clockwise due to its own gravity, and the rotating platform 6 will drive the round display shell to rotate 90 degrees, so that the purpose of rotating the round display shell 90 degrees can be achieved, thereby facilitating the round display shell to move right into the packaging box for packaging. When the rotating platform 6 moves downward to reset, it will drive the abutment 17 and the contact rod 19 to move downward to reset. When the contact rod 19 moves to the flat surface of the wedge plate 191, it will push the contact rod 19 and the abutment 17 to move right. The abutment 17 moves rightward and slowly squeezes the rotating platform 6, which makes the rotating platform 6 reverse and reset, and the spring 2 18 is stretched to reset.

[0039] like Figure 5 As shown, it also includes a first wedge block 20 symmetrically arranged front and back, the first wedge blocks 20 are all slidably connected to the moving seat 2, and a spring three 21 is connected between the left side of the first wedge block 20 and the moving seat 2.

[0040] After the lifting block 5 moves upward to the top and the round display shell rotates 90 degrees, the lifting block 5 and the round display shell will continue to move to the right. However, if the rack 15 and the gear 14 are still in meshing state, the lifting block 5 will continue to move upward, and the lifting block 5 cannot move further upward at the top position, so it will get stuck. Therefore, at this time, people need to manually push the moving body 16 to move left. The moving body 16 moves left and drives the rack 15 to move downward. After the rack 15 moves downward and separates from the gear 14, the lifting block 5 may fall. Therefore, a first wedge block 20 is provided. After block 5 moves up and contacts the wedge-shaped surface of the first wedge block 20, it will push the first wedge block 20 to move to the left, and spring three 21 will be compressed. When the lifting block 5 moves up and separates from the wedge-shaped surface of the first wedge block 20, spring three 21 will drive the first wedge block 20 to move to the right and reset. In this way, the top surface of the first wedge block 20 will press against the lifting block 5 to prevent the lifting block 5 from falling. After the lifting block 5 pushes the round display shell to the packaging box, the lifting block 5 moves to the left and resets. Then people can pull the first wedge block 20 to move to the left and reset. The first wedge block 20 then releases the lifting block 5, and the lifting block 5 will move downward and reset due to its own gravity.

[0041] like Figure 5-Figure 6 As shown, it also includes a hollow column 22, which is fixedly connected to the upper left side of the mobile seat 2, and the hollow column 22 is sleeved on the outside of the telescopic rod of the multi-stage cylinder 3. The top of the telescopic rod of the multi-stage cylinder 3 is fixedly connected to the pulling frame 24, and a slide groove is opened on the upper part of the hollow column 22. The slide groove and the pulling frame 24 are slidably connected. The front and rear sides of the mobile seat 2 are slidably connected with the pulling body 23, and the left part of the pulling body 23 is squeezed and fitted with the pulling frame 24. Protrusions are provided on the upper and lower sides of the first wedge block 20, and the protrusions are squeezed and fitted with the right part of the pulling body 23.

[0042] It also includes a second wedge block 26, which is symmetrically arranged and slidably connected to the telescopic rod of the multi-stage cylinder 3. A card slot is provided on the front and rear sides of the hollow column 22, and the card slot and the second wedge block 26 are squeezed together. A spring four 25 is connected between the inner side of the second wedge block 26 and the telescopic rod of the multi-stage cylinder 3. The front and rear sides of the upper left part of the base 1 are connected to a wedge frame 27, and the wedge frame 27 is squeezed together with the second wedge block 26.

[0043] In order to replace the manual pulling of the first wedge block 20, the following solution is adopted:

[0044] The telescopic rod of the multi-stage cylinder 3 is connected to the movable seat 2 as described above, and this solution proposes a hollow column 22. The telescopic rod of the multi-stage cylinder 3 and the movable seat 2 are connected through the hollow column 22. When the telescopic rod of the multi-stage cylinder 3 is extended, the telescopic rod of the multi-stage cylinder 3 will first drive the second wedge block 26 and the spring four 25 to move right. After the second wedge block 26 and the card slot are squeezed against each other, the second wedge block 26 will move to the side close to each other, and the spring four 25 will be compressed. Subsequently, the second wedge block 26 moves along with the multi-stage cylinder 3 moves right together. After the telescopic rod of the multi-stage air cylinder 3 contacts the left side of the moving base 2, it pushes the moving base 2 to move right, thereby achieving the purpose of packing the round display shells. Then, when the telescopic rod of the multi-stage air cylinder 3 contracts and resets, the telescopic rod of the multi-stage air cylinder 3 drives the second wedge block 26 to move left. When the second wedge block 26 contacts the card slot, the spring 25 drives the second wedge block 26 to reset to the side away from each other, and the second wedge block 26 is stuck in the card slot, and the flat surface of the second wedge block 26 rests on the card slot. The left side of the slot, so the second wedge block 26 will drive the hollow column 22 to move to the left, the hollow column 22 moves to the left and drives the moving seat 2 to move to the left and reset. After the moving seat 2 moves to the left and resets, the moving seat 2 and the hollow column 22 automatically stop moving, and the telescopic rod of the multi-stage cylinder 3 continues to retract and drive the second wedge block 26 and the pulling frame 24 to move to the left. The pulling frame 24 moves to the left and pulls the pulling body 23 to move to the left. After the pulling body 23 moves to the left and contacts the protrusion, it drives the first wedge block 20 to Move left to release the lifting block 5, so that the lifting block 5 can automatically descend. At the same time, the second wedge block 26 moves left and contacts the wedge surface of the wedge frame 27, so that the second wedge block 26 moves inward again into the hollow column 22. In this way, the left movement of the second wedge block 26 will not cause the hollow column 22 to move left, nor will it affect the pulling frame 24 pulling the pulling body 23. When the telescopic rod of the multi-stage cylinder 3 is extended, it will drive the second wedge block 26 and the pulling frame 24 to move right and reset, and the second wedge block 26 will be re-engaged in the slot.

[0045] like Figure 7 As shown, it also includes an inclined rail 28, which is respectively connected to the pulling body 23. The front and rear sides of the movable seat 2 are slidably connected to the movable plate 30. The movable plate 30 is fixedly connected to the extrusion frame 29. The extrusion frame 29 and the inclined rail 28 are extruded and matched. The movable plate 30 is rotatably connected to the cache block 31. The cache block 31 is extruded and matched with the lifting block 5. A torsion spring is provided between the cache block 31 and the movable plate 30.

[0046] When the lifting block 5 is lowered, it may fall rapidly due to its own gravity, which may cause the lifting block 5 to collide violently with the moving seat 2. Therefore, a buffering mechanism is provided. When the pulling frame 24 moves to the left and pulls the pulling body 23 to move to the left, the pulling body 23 will drive the inclined rail 28 to move to the left, and the inclined rail 28 will push the extrusion frame 29 to move to the side away from each other, and the extrusion frame 29 will drive the moving plate 30 and the cache block 31 to move as well. The cache block 31 will be blocked under the lifting block 5. Therefore, the cache block 31 will be squeezed intermittently during the descending process of the lifting block 5. The cache block 31 will rotate under pressure, and the torsion spring will be twisted. After the cache block 31 and the lifting block 5 are separated, the torsion spring drives the cache block 31 rotates and resets, so that the lifting block 5 can be decelerated by the buffer block 31. It should be noted that when the inclined rail 28 pushes the extrusion frame 29 to move, the pulling body 23 has not yet contacted the protrusion, nor has it pushed the first wedge block 20 to the left. Only after the buffer block 31 is completely moved to the bottom of the lifting block 5, the first wedge block 20 will move to the left. In this way, the buffer block 31 can be moved to the destination first before releasing the lifting block 5, thereby achieving the purpose of buffering and deceleration. When the pulling body 23 moves to the right and resets, it will drive the inclined rail 28 to move to the right and reset. The inclined rail 28 drives the extrusion frame 29 and the moving plate 30 to push and reset, and then drives the cache block 31 to move and reset.

[0047] Example 3: A packaging method for a production and packaging mechanism of round display shells, comprising the following steps:

[0048] Step 1: The multi-stage cylinder 3 controls the moving base 2 to move right, and the moving base 2 drives the rotating platform 6 and the round display shell to move right together;

[0049] Step 2: With the cooperation between the rack 15 and the gear 14, the gear 14 rotates, causing the pull rope 13 to pull the rotating platform 6 and the round display shell to rise. After the round display shell contacts the plastic film, the plastic film is pushed upward, causing the annular knife 11 to automatically cut the plastic film. As a result, the plastic film can be automatically wrapped around the end of the round display shell.

[0050] Step 3: The rodless cylinder 7 then controls the movable frame 8 and the annular blade 11 to lift away from the round shell. The rotating platform 6 continues to move upward, driving the abutment 17 and the contact rod 19 upward. After the contact rod 19 contacts the wedge-shaped surface of the wedge plate 191, the spring 2 18 drives the abutment 17 to the left, releasing the rotating platform 6. As a result, the rotating platform 6 automatically rotates 90 degrees.

[0051] Step 4: The rotating platform 6 continues to move the round display shell to the right and inserts it into the packaging box for packaging.

[0052] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
