The heat-sealing and cutting assembly 60 is located below the pull roller assembly 50 and is used to heat-seal and cut the packaging bag in a horizontal direction. A feeding hopper is fixedly arranged on the frame 10. The feeding hopper is located directly above the heat-sealing and cutting assembly 60 and below the bag-pulling assembly 30.

[0024] In use, the staff places the packaging bag roll on the feeding roller 20, then pulls the unsealed packaging bag through the bag pulling assembly 30 and puts the packaging bag on the feed hopper. The sides of the packaging bag are not sealed. The staff pulls the two sides of the packaging bag to the sealing assembly 40 and the pull wheel assembly 50. Through the above steps, the preparation work for setting the packaging bag roll is completed. The operator starts the packaging machine. The external conveyor transports the hardware parts along the side opening of the unsealed packaging bag into the feeding hopper. The hardware parts fall into the bottom of the packaging bag through the feeding hopper. The sealing assembly 40 heat-presses the side of the packaging bag. The bag pulling assembly 30 and the pull wheel assembly 50 simultaneously pull the packaging bag downwards. Then, the packaging bag containing the hardware parts moves downwards to below the heat sealing and cutting assembly 60. The heat sealing and cutting assembly 60 performs horizontal heat sealing and cutting on the top of the packaging bag containing the hardware parts. The packaging bag containing the hardware parts falls down, completing the packaging process for a set of hardware parts. After that, simply repeat the above steps to carry out assembly line production.

[0025] Preferably, the bag-pulling assembly 30 includes a first support frame 31, which is fixedly mounted on the frame 10. A first drive motor 32 is fixedly mounted on the side of the first support frame 31. A rotating shaft 33 is fixedly connected to the output end of the first drive motor 32. The rotating shaft 33 is horizontally mounted on the first support frame 31. A support cylinder 34 is fixedly mounted on the rotating shaft 33. A roller 35 that rotates around its own axis is mounted on the first support frame 31. The roller 35 is located directly in front of the support cylinder 34. The gap between the support cylinder 34 and the roller 35 is only for the packaging bag to pass through.

[0026] Preferably, the edge sealing assembly 40 includes a second support frame 41, which is fixedly mounted on the frame 10. A first cylinder 42 is horizontally fixedly mounted on the second support frame 41. The output end of the first cylinder 42 is fixedly connected to a vertical first hot press plate 43. The hot pressing direction of the first hot press plate 43 is towards the right. A second hot press plate 44 is fixedly mounted on the second support frame 41. The position of the second hot press plate 44 is opposite to that of the first hot press plate 43, and the hot pressing direction is towards the left.

[0027] Preferably, the output end of the first cylinder 42 is fixedly connected to the mounting frame 45, the first hot press plate 43 is fixed on the mounting frame 45, two first slide rods 46 are vertically fixed on the mounting frame 45, the first cylinder 42 is set inside the mounting frame 45 and between the two first slide rods 46, and two first slide cylinders 47 are fixedly set on the second support frame 41. The two first slide cylinders 47 are respectively sleeved on the first slide rods 46 and slidably connected. By setting the first slide rods 46 and the first slide cylinders 47, the stability of the mounting frame 45 when moving horizontally can be improved, ensuring the side heat sealing effect of the packaging bag and making the product more beautiful.

[0028] Preferably, the pull wheel assembly 50 includes a second drive motor 51, which is fixedly mounted on the back of the frame 10. The output end of the second drive motor 51 is fixedly fitted with a first gear 52. Two horizontal rotating rods 53 are rotatably connected to the frame 10.

[0029] Preferably, the heat-sealing and cutting assembly 60 includes a third support frame 61, which is fixedly mounted on the frame 10. Opposing second cylinders 62 and 63 are fixedly mounted at the front and rear ends of the third support frame 61. A first connecting plate 64 is fixedly connected to the output end of the second cylinder 62. A third hot press plate 65 is horizontally fixedly mounted on the first connecting plate 64. A second connecting plate 66 is fixedly connected to the output end of the third cylinder 63. A fourth hot press plate 67 and a cutting tooth 68 are horizontally fixedly mounted on the second connecting plate 66. The third hot press plate 65 and the fourth hot press plate 67 are opposite to each other. The cutting tooth 68 is located below the fourth hot press plate 67 and both are in the same direction.

[0030] Preferably, two horizontal second slide rods 69 are fixedly installed on the third support frame 61. Second slide cylinders 70 are fixedly installed on the left and right sides of the first connecting plate 64 and the second connecting plate 66 respectively. The second slide cylinders 70 are sleeved on the second slide rods 69 and the two are slidably connected. By setting the second slide rods 69 and the second slide cylinders 70, the stability of the first connecting plate 64 and the second connecting plate 66 when moving horizontally can be improved, ensuring the horizontal heat sealing and cutting effect of the packaging bag and making the product more beautiful.

[0031] Preferably, two opposing limiting discs 80 are installed on the feeding roller 20. The limiting discs 80 are used to clamp the packaging bag roll on the feeding roller 20 to prevent the packaging bag roll from swaying left and right when the packaging machine is working, which would affect the normal use of the packaging machine.

[0032] Preferably, a baffle 90 is fixedly installed on the frame 10. The baffle 90 is vertically installed directly above the sealing assembly 40 and below the bag-pulling assembly 30. The baffle 90 can prevent the side of the unsealed packaging bag from excessively approaching the sealing assembly 40, thus avoiding affecting the sealing effect of the side of the packaging bag.

[0033] Preferably, a discharge plate 100 is fixedly installed on the frame 10. The discharge plate 100 is located directly below the heat sealing and cutting assembly 60. The discharge plate 100 is inclined downward. Vertical limiting plates 110 are fixedly installed on the left and right sides of the upper surface of the discharge plate 100. The discharge plate 100 plays a role in bearing and buffering, preventing the hardware parts in the packaging bag from directly contacting the ground, causing the hardware parts to be bumped and affecting the yield.

[0034] The working principle of this embodiment, and its more specific process, are as follows:

[0035] The worker places the packaging bag roll onto the feeding roller 20 and installs the limiting wheel 80 on the feeding roller 20 to clamp the packaging bag roll. The worker pulls the unsealed packaging bag through the gap between the support cylinder 34 and the roller 35 and puts the packaging bag onto the feed hopper. The sides of the packaging bag are not sealed. The worker pulls both sides of the packaging bag between the first hot press plate 43 and the second hot press plate 44, and between the two pulling wheels 55. Through the above steps, the preparation work for setting the packaging bag roll is completed. The operator starts the packaging machine. The external conveyor transports the hardware components along the side opening of the unsealed packaging bag into the feed hopper. The hardware components fall into the bottom of the packaging bag through the feed hopper. The first cylinder 42 starts, driving the first hot press plate 43 to move towards the second hot press plate 44. The first hot press plate 43 and the second hot press plate 44 heat-press and seal the side of the packaging bag between them. The first drive motor 32 starts, driving the rotating shaft 33 to rotate, which in turn drives the support cylinder 34 to rotate. The support cylinder 34 drives the packaging bag between the support cylinder 34 and the roller 35 to move downward. At the same time, the second drive motor 51 starts, driving the first gear 52 to rotate. The first gear 52 meshes with the second gear 54 in contact with it, causing the two second gears 54 to rotate in opposite directions. This causes the rotating rod 53 to rotate in opposite directions, which in turn causes the pulling wheels 55 to rotate in opposite directions. The two pulling wheels 55 together pull the packaging bag downwards. Then, the packaging bag containing the hardware moves downwards to below the heat-sealing and cutting assembly 60. The second cylinder 62 and the third cylinder 63 start simultaneously. The second cylinder 62 drives the third hot press plate 65 to move towards the fourth hot press plate 67. The third cylinder 63 drives the fourth hot press plate 67 and the cutting tooth 68 to move towards the third hot press plate 65. The third hot press plate 65 and the fourth hot press plate 67 heat-press and seal the top of the packaging bag containing the hardware. The cutting tooth 68 cuts off the sealed area. The packaging bag containing the hardware falls onto the discharge plate 100 and slides down along the discharge plate 100, completing the packaging process for a set of hardware. After that, the above steps can be continuously repeated to carry out assembly line production.

[0036] The vertical packaging machine of this utility model is equipped with a bag-pulling assembly 30, an edge-sealing assembly 40, a pull-roller assembly 50, and a heat-sealing and cutting assembly 60 on the frame 10. The bag-pulling assembly 30 is used to pull the packaging bag on the feeding roller 20 downward, the edge-sealing assembly 40 is used to heat-seal the side of the packaging bag in the vertical direction, the pull-roller assembly 50 is used to pull the side of the heat-sealed packaging bag downward, and the heat-sealing and cutting assembly 60 is used to heat-seal and cut the packaging bag in the horizontal direction. This vertical packaging machine can integrate the heat-sealing and cutting processes of the packaging bag into one device, resulting in high working efficiency.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
