Detailed implementation manners

[0039] This specific embodiment is only an interpretation of the present invention and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0040] An automatic packaging machine for seals includes a feeding mechanism and a packaging mechanism. The feeding mechanism includes a feed hopper 11, a climbing conveyor belt 12, a first horizontal conveyor belt 13, and a second horizontal conveyor belt 14.

[0041] The climbing conveyor belt 12 is arranged obliquely upward, and its bottom is located inside the feeding hopper 11. One end of the first horizontal conveyor belt 13 is located below the discharge opening of the climbing conveyor belt 12, and the other end extends along the second direction. Here, the first direction refers to the conveying direction of the second horizontal conveyor belt 14. The second horizontal conveyor belt 14 is arranged below the discharge end of the first horizontal conveyor belt 13, and the conveying direction of the second horizontal conveyor belt 14 is perpendicular to the direction of the first horizontal conveyor belt 13. Here, the conveying direction of the second horizontal conveyor belt 14 is the first direction.

[0042] A return channel 15 is fixed to the side of the first horizontal conveyor belt 13 close to the feeding hopper 11, and a return plate 16 is hinged to the side of the first horizontal conveyor belt 13 away from the return channel 15. The return channel 15 is arranged obliquely downward and extends into the feeding hopper 11. When the return plate 16 is parallel to the second direction, the seal passes through the first horizontal conveyor belt 13 and enters the second horizontal conveyor belt 14. When the return plate 16 rotates to be inclined and points to the inlet of the return channel 15, the seal returns to the feeding hopper 11 through the return channel 15; when the packaging mechanism needs to stop working and excess seals need to be returned, the return plate 16 is inclined.

[0043] The seal is of an annular structure. A side plate 23 is installed on each side of the second horizontal conveyor belt 14. The side plate 23 extends along the first direction. The seal passes between the two side plates 23. Both ends of each side plate 23 are connected to a link mechanism. By rotating the connection mechanism, the position of the side plate 23 in the second direction is adjusted, that is, the distance between the two side plates 23 is adjusted to accommodate seals of different sizes.

[0044] The link mechanism includes a first link 17 and a second link 18. One end of the first link 17 is hinged to the second horizontal conveyor belt 14, the other end of the first link 17 is hinged to one end of the second link 18, and the other end of the second link 18 is hinged to a fixed ear 22 on the side plate 23. The fixed ear 22 is fixed to the side plate.

[0045] The feeding mechanism further includes a third horizontal conveyor belt 19, which extends along the first direction and is docked with the second horizontal conveyor belt 14.

[0047] Specifically, the blanking pusher plate 32 is pushed by the first driving plate device to expand and contract in the second direction. The first driving plate device includes a driving plate motor 33, a transmission disk 34, a transmission rod 35, a first slide rail 36, and a first slider 37. The driving plate motor 33 is fixed on the mounting bracket 2. The transmission disk 34 is a disk and its center is fixed on the output shaft of the driving plate motor 33. One end of the transmission rod 35 is rotatably connected to the transmission disk 34, and the other end is rotatably connected to the first slider 37. The first slider 37 is installed on the first slide rail 36, and the first slide rail 36 extends in the second direction. The connection point of the transmission rod 35 and the transmission disk 34 deviates from the center of the transmission disk 34. In this way, the driving plate motor 33 drives the first slider 37 to slide back and forth along the first slide rail 36. The blanking pusher plate 32 includes a connection part 321 fixed to the first slider 37 and a pushing part 322 vertically connected to the connection part 321. A straight slot 323 penetrating through both ends in the second direction is opened on the pushing part 322. The straight slot 323 is used for the receiving rod 31 to penetrate when pushing the seal to the receiving rod 31.

[0048] A partition plate 4 is installed at the discharging end of the third horizontal conveyor belt 19. The partition plate 4 is moved in the first direction by the third driving device.

The transverse motor 46 is fixed to the mounting bracket 2 and its output shaft is fixed to the first screw rod 47. The first screw rod 47 is threadedly connected to the first guiding block 49. The first guiding rod 48 passes through the first guiding block 49 and is fixed to the mounting bracket 2. The positioning plate 45 is fixed to the first guiding block 49 through a connecting rod.

[0050] The receiving rod 31 can move in the vertical direction while expanding and contracting in the second direction. A mounting seat 5 is arranged on the side of the mounting bracket 2 away from the third horizontal conveyor belt 19. The mounting seat 5 moves up and down through a driving seat device. The pushing rod device is fixed on the mounting seat 5. The driving seat device includes a cylinder three 51, a vertical guiding rod 52, and a base 53. The second guiding rod 52 is vertically fixed on the mounting bracket 2. The base 53 is fixed at the top of the second guiding rod 52. The cylinder three 51 is fixed at the top of the base 53. The piston rod of the cylinder three 51 passes through the base 53 and is connected to the mounting seat 5. The second guiding rod 52 also passes through the mounting seat 5. The pushing rod device includes a cylinder four 54 fixed on the mounting seat 5. The piston rod of the cylinder four 54 is fixed to the receiving rod 31.

[0051] A material receiving plate 55 is arranged below the material receiving rod 31. An output material pushing plate 56 is arranged on one side of the material receiving plate 55 close to the second horizontal conveyor belt 14. On the other side, a limiting rod 57, a hot cutting knife 58, and a pressing plate 59 are arranged in sequence along the first direction away from the output material pushing plate 56. The limiting rod 57 is farther away from the output material pushing plate 56 than the material receiving rod 31.

[0052] A second slide rail 61 is fixed on the mounting frame 2. The second slide rail 61 extends along the second direction. A second slide block 62 is mounted on the second slide rail 61. An installation plate 63 is fixed above the second slide block 62. A first air cylinder 64 is fixed on the mounting frame 2. The piston rod of the first air cylinder 64 is fixed to the installation plate 63. The material receiving plate 55 is fixed above the installation plate 63, and the upper end surface of the material receiving plate 55 is a material receiving surface. The material receiving surface is arranged to incline upward from the side close to the output material pushing plate 56 to the side close to the hot cutting knife 58.

[0053] The output material pushing plate 56 is pushed by a second driving plate device to expand and contract along the first direction. The second driving plate device includes a first motor 65, a second screw rod 66, a second guide rod 52, and a second guide block 68. A base is fixed on the installation plate 63. The first motor 65 is fixed on the base. The second screw rod 66 is fixed to the output shaft of the first motor 65. The second guide rod 52 is fixed on the base and passes through the second guide block 68. The second guide block 68 is threadedly connected to the second screw rod 66. The output material pushing plate 56 is fixed to the second guide block 68 through a connecting rod. The output material pushing plate 56 is a telescopic structure, including a fixed plate body 561 and a sliding plate body 562. The fixed plate body 561 is fixed to the second guide block 68 through a connecting rod. The sliding plate body 562 is sleeved on the fixed plate body 561 and can slide relative to the fixed plate body 561 along the second direction.

[0054] A blocking plate 71 is arranged at one end of the material receiving plate 55 close to the blanking pushing plate 32, and a material retaining plate 72 is arranged at the end far from the blanking pushing plate 32. The height of the material retaining plate 72 is higher than the height of the material receiving rod 31 during material receiving. The height of the blocking plate 71 is lower than the height of the material receiving rod 31 during material receiving. Notches 73 for the material receiving rod 31 to pass through are formed on both the blocking plate 71 and the material retaining plate 72. The blocking plate 71 abuts against the fixed plate body 561 of the output material pushing plate 56, and the material retaining plate 72 abuts against the sliding plate body 562 of the output material pushing plate 56.

[0055] A third slide rail 74 is fixed on the installation plate 63. A third slide block 75 is installed on the third slide rail 74. A positioning bolt 76 is threadedly connected to the third slide block 75 and vertically passes through the third slide block 75 to abut against the upper surface of the installation plate 63 so that the third slide block 75 is in a locked state. A first driving device is installed on the third slide block 75. The first driving device includes a second air cylinder 77. A connecting plate is fixed to the piston rod of the second air cylinder 77, and the connecting plate is fixed to the material retaining plate 72.

[0056] The limiting rod 57 is fixed on the mounting frame 2, and the height of the limiting rod 57 is lower than the height of the material receiving rod 31 during material receiving and higher than the height of the material receiving rod 31 during discharging.

[0057] On the side of the material receiving plate 55 away from the discharging pushing plate 56, there is a discharging plate 8. Between the material receiving plate 55 and the discharging plate 8, there is a top plate 81. The top plate 81 is driven by a lifting mechanism to move up and down above the upper surface of the discharging plate 8 or flush with the upper surface of the discharging plate 8.

[0058] The lifting mechanism includes a lifting motor 82, a third screw 83, a guide rail 84, and a transmission block 85. A vertically arranged support plate 86 is fixed on the mounting frame 2. The lifting motor 82 is fixed to the support plate 86, and the third screw 83 is fixed to the output shaft of the lifting motor 82. The guide rail 84 is vertically fixed on the support plate 86, and the transmission block 85 is slidably arranged on the guide rail 84. The third screw 83 passes through the transmission block 85 and is threadedly connected to the transmission block 85. A top rod 87 is fixed to the bottom of the top plate 81, and the top rod 87 is fixed to the transmission block 85. On both sides of the top rod 87 at the bottom of the top plate 81, third guide rods are fixed. The third guide rods vertically pass through the mounting frame 2 and can move up and down relative to the mounting frame 2.

[0059] Between the top plate 81 and the material receiving plate 55, there is also an adjusting plate 88 fixed to the mounting frame 2 by bolts. The adjusting plate 88 is also located below the limiting rod 57. The upper surface of the adjusting plate 88 is also an inclined surface, and the inclination direction is the same as that of the material receiving surface. The upper surface of the adjusting plate 88 and the material receiving surface are on the same inclined plane, and the highest point of the upper surface of the adjusting plate 88 is flush with the upper surface of the discharging plate 8.

[0060] The hot cutting knife 58 is driven to move up and down by a knife driving device. The knife driving device includes a knife driving cylinder 91. The knife driving cylinder 91 is fixed to the mounting frame 2, and the piston rod of the knife driving cylinder 91 is connected to a T-shaped tool holder 92. The hot cutting knife 58 is fixed to the T-shaped tool holder 92 through a connecting rod.

[0061] The pressing plate 59 is driven to press down by a lifting assembly. When both the hot cutting knife 58 and the pressing plate 59 are working, the height of the pressing plate 59 is lower than the height of the hot cutting knife 58. The lifting assembly includes a lifting cylinder 93 fixed to the mounting frame 2. The lifting cylinder 93 is vertically arranged, and the bottom of its piston rod is fixed with a base plate 94. A vertical rod 95 is vertically penetrated through the base plate 94, and the pressing plate 59 is fixed to the bottom of the vertical rod 95. A spring 96 is sleeved on the vertical rod 95. The upper end of the spring 96 is fixed to the base plate 94, and the lower end is fixed to the pressing plate 59.

[0062] On both sides of the discharging plate 8, there are a first baffle 97 and a second baffle 98. The first baffle 97 is closer to the discharging pushing plate 56 than the second baffle 98. The first baffle 97 is located below the pressing plate 59 and the hot cutting knife 58. The first baffle 97 is hinged to the second baffle 98. A flipping mechanism for driving the first baffle 97 to flip outwards is installed on the second baffle 98.

[0063] The inner side walls of the first baffle 97 and the second baffle 98 on one side are flush with the inner side wall of the blocking plate 71, and the inner side walls of the first baffle 97 and the second baffle 98 on the other side are flush with the inner side wall of the material baffle 72. The lengths of the hot cutting knife 58 and the pressing plate 59 are both greater than the distance between the blocking plate 71 and the material baffle 72 (i.e., the two first baffles 97 or the two second baffles 98). When the first baffle 97 is in the flush state, a part of it is located above the discharge plate 8, and the other part is located above the top plate 81 and the adjustment plate 88. After the first baffle 97 rotates, the first baffle 97 is all located above the discharge plate 8, avoiding the hot cutting knife 58 and the pressing plate 59.

[0064] The flipping mechanism includes a third air cylinder 100 rotatably connected to the outer side wall of the second baffle 98. The piston rod of the third air cylinder 100 is rotatably connected to a first connecting rod 99, and the end of the first connecting rod 99 away from the piston rod is rotatably connected to the first baffle 97.

[0065] The top of the mounting frame 2 is provided with two parallel material feeding rollers 101 rotatably connected to the mounting frame 2, and one of the material feeding rollers 101 is connected to a material feeding motor 102. The film roll is placed between the two material feeding rollers 101 and abuts against the material feeding rollers 101. A guiding frame is arranged beside the material feeding rollers 101, and the film bypasses the guiding frame and passes downward through the gap between the material receiving plate 55 and the adjustment plate 88 and hangs down, and the film also abuts against one side of the limiting rod 57 close to the discharge pushing plate 56.

[0066] Working process: The seal is placed into the feeding hopper 11 and enters the third horizontal conveyor belt 19 through the climbing conveyor belt 12, the first horizontal conveyor belt 13, and the second horizontal conveyor belt 14. When the seal moves to abut against the positioning plate 45, at this time, the partition plate 4 moves downward under the drive of the second air cylinder 44 to separate the next seal from the seal abutting against the positioning plate 45, and moves upward during the next feeding, so as to ensure that only one seal is pushed by the discharge pushing plate 32 each time.

[0067] The discharge pushing plate 32 pushes the seal to be sleeved on the receiving rod 31. At this time, the height of the receiving rod 31 is higher than the height of the blocking plate 71, so that the blocking plate 71 does not affect the sleeving of the seal on the receiving rod 31. Thus, when the number of seals on the receiving rod 31 reaches the predetermined number, the first air cylinder 41 drives the side sealing plate 43 to block between the discharge pushing plate 32 and the receiving rod 31.

[0068] The receiving rod 31 moves downward under the drive of the third air cylinder 51 until the seal abuts against the receiving surface. At this time, the receiving rod 31 is simultaneously located in the notch 73 of the material baffle 72 and the blocking plate 71. The fourth air cylinder 54 drives the receiving rod 31 to retract, and the seal abuts against the discharge pushing plate 56 under its own weight due to the inclined setting of the receiving surface.

[0069] Then, the second cylinder 77 pushes the baffle plate 72, and the baffle plate 72 pushes the sliding plate body 562 so that the interval between the baffle plate 72 and the blocking plate 71 is equal to the length of the sealing member arranged along the second direction, that is, the sealing member is pressed tightly.

[0070] Then the first motor 65 starts to drive the discharge push plate 56 until the seal is located on the discharge plate 8 and below the pressure plate 59. At this time, the sagging film forms a horizontally placed U-shaped structure, and the opening of the U-shaped structure faces the discharge push plate 56, and the seal is located at the U-shaped part of the U-shaped structure.

[0071] Afterwards, the pressing plate 59 is lowered and pressed on the sealing member by the lifting cylinder 93. The first baffle plate 97 is turned outward to the discharge plate 8 and staggered with the hot cutting knife 58.

[0072] Afterwards, the hot cutting knife 58 is driven down by the knife driving cylinder 91 to cut and heat-seal the opening of the U-shaped structure.

[0073] After that, the hot cutter 58 and the pressing plate 59 are reset at the same time, and then the lifting motor 82 drives the top plate 81 to lift and push the seal outward. The film is unwound again and the side sealing plate 43 is reset. The film will sag again under the action of gravity and pass through the gap between the receiving plate 55 and the adjusting plate 88. The next work starts.
