[0040] In this implementation scheme, when the motor 8 rotates forward to drive the reciprocating lead screw 10 to rotate, the two columns 17 can be rotated, so that the two rotating rods 18 can be rotated. In this way, the two clamping blocks 19 can approach each other, and the two rubber blocks 20 can clamp the bag mouth of the packaging bag. When the reciprocating lead screw 10 rotates, the air pipe 1 7 can also move downward. When the bag mouth of the packaging bag is clamped, the air pipe 1 7 can also be inserted into the air guide pipe 2 13. In this way, the clamping work and the insertion work of the inflation nozzle can be carried out synchronously;

[0041] Among them, in order to achieve the purpose of sealing, the present device adopts the following technical solutions: The heat-sealing assembly includes two first boxes 26, which are respectively located at the rear sides of the two rotating rods 18. There are stabilizing blocks 27 fixedly connected between the two first boxes 26 and the two rotating rods 18 respectively. Through holes 1 are provided on the front sides of the two first boxes 26. Piston 1 28 is slidably arranged inside the two first boxes 26. Moving rod 1 29 is fixedly connected to the front sides of the two piston 1 28 respectively. The two moving rods 1 29 respectively penetrate through the two through holes 1 and are in sliding contact with them. Clamping blocks 30 are fixedly connected to the front ends of the two moving rods 1 29. Electric heating blocks 31 are fixedly embedded on the two clamping blocks 30. The two electric heating blocks 31 are respectively located at the rear sides of the two through holes 2. The inner wall of the front side of the frame 2 is connected with a reciprocating lead screw 2 32. The rear end of the reciprocating lead screw 2 32 is embedded in the rotating shaft 1 9 and is connected to it through a one-way bearing. A sliding seat 2 33 is sleeved outside the reciprocating lead screw 2 32. The sliding seat 2 33 is connected to the reciprocating lead screw 2 32 through a ball screw pair. Two second boxes 34 are fixedly connected to the inner wall of the bottom of the frame 2. Through holes 2 are provided on the front sides of the two second boxes 34. Piston 2 35 is slidably arranged inside the two second boxes 34. Moving rod 2 36 is fixedly connected to the front sides of the two piston 2 35 respectively. The two moving rods 2 36 respectively penetrate through the two through holes 2 and are in sliding contact with them. Connecting blocks 37 are fixedly connected between the two moving rods 2 36 and the sliding seat 2 33 respectively. Hose 2 38 is fixedly connected between the two second boxes 34 and the two first boxes 26 respectively. The two hose 2 38 penetrate through the two through slots 1;

[0042] Among them, in order to achieve the purpose of supporting the bag mouth, the present device adopts the following technical solutions: Two cavities 1 are provided on the support rod 6, which are respectively located on the front and rear sides of the air pipe 1 7. Connecting rods 39 are fixedly connected to the interiors of the two cavities 1 respectively. Arc-shaped rods 40 are slidably sleeved outside the two connecting rods 39 respectively. The two arc-shaped rods 40 are respectively slidably arranged inside the two cavities 1. Springs 41 are fixedly connected to the inner sides of the two arc-shaped rods 40 respectively. The inner ends of the two springs 41 are respectively fixedly connected to the two cavities 1. The two springs 41 are respectively sleeved outside the two connecting rods 39. The bag mouth of the packaging bag is sleeved on the two arc-shaped rods 40. Then, under the action of the two springs 41, the two arc-shaped rods 40 will be pushed outwards all the time. In this way, the two arc-shaped rods 40 can support the bag mouth of the packaging bag;

[0043] Among them, in order to achieve the purpose of reducing wear, the present device is implemented by the following technical solution: The reciprocating lead screw 10 is connected to the bottom plate 1 and the L-shaped plate 3 through bearings, the column 17 is connected to the connecting plate 4 and the bottom plate 1 through bearings, and the reciprocating lead screw 32 is connected to the frame 2 through bearings. Connecting through bearings can reduce wear.

[0044] The use process of the present invention is as follows: When the light bulb needs to be packaged, the light bulb is installed in the packaging bag, and then the bag mouth of the packaging bag is sleeved on the two arc-shaped rods 40. Then, under the action of the two springs 41, the two arc-shaped rods 40 will always be pushed outwards. In this way, the two arc-shaped rods 40 can support the bag mouth of the packaging bag, and at the same time, the bottom end of the air pipe 1 is located in the packaging bag;

[0045] Then control the motor 8 to rotate forward. The forward rotation of the motor 8 drives the rotation of the rotating shaft 1. Since the reciprocating lead screw 32 is connected to the rotating shaft 1 through a one-way bearing, and the bevel gear 24 is connected to the rotating shaft 1 through a one-way bearing, when the motor 8 rotates forward, the bevel gear 24 rotates and the reciprocating lead screw 32 does not rotate. The rotation of the bevel gear 24 drives the rotation of the bevel gear 1, and the rotation of the bevel gear 1 drives the rotation of the reciprocating lead screw 10. The rotation of the reciprocating lead screw 10 drives the sliding seat 11 to move downward first. When the sliding seat moves downward, the two bumps 22 can move downward. Since the two bumps 22 are embedded in the two spiral grooves 21, when the two bumps 22 move downward, the two columns 17 can rotate. The rotation of the two columns 17 drives the rotation of the two rotating rods 18, so that the two clamping blocks 19 can approach each other, and the two rubber blocks 20 can clamp the bag mouth of the packaging bag. At the same time, the air pipe 1 is located in the two grooves. When the sliding seat 11 moves downward, the moving plate 12 can also move downward. When the moving plate 12 moves downward, the air pipe 2 can move downward, so that the bottom end of the air pipe 2 can be inserted into the air pipe 1. When the downward movement stroke of the sliding seat 11 ends, the bag mouth of the packaging bag is just clamped, and the air pipe 2 is just inserted into the air pipe 1. In this way, the clamping work and the insertion work of the inflation nozzle can be carried out synchronously, which can reduce the inflation steps and reduce the preface time;

[0046] Then, air can enter the second trachea 13 and the first trachea 7 through the first hose 16, so that air can be filled into the packaging bag. After the inflation is completed, control the motor 8 to reverse. The same principle is that the second reciprocating lead screw 32 rotates, and the second bevel gear 24 does not rotate. The rotation of the second reciprocating lead screw 32 drives the second sliding seat 33 to move backward first, so that the two connecting blocks 37, the two moving rods and the two second pistons 35 move backward. Then, under the action of the two second hoses 38, the air in the two second boxes 34 enters the two first boxes 26, so that the two first pistons 28, the two first moving rods 29 and the two clamping blocks 30 move towards the middle. Then, the two electric heating blocks 31 can clamp the bag mouth of the packaging bag, and at the same time, control the two electric heating blocks 31 to work to heat-seal the packaging bag, thereby realizing sealing.

[0047] After the sealing is completed, control the motor 8 to continue to reverse, so that the second sliding seat 33 can move forward. Then, components such as the second sliding seat 33, the second moving rod 36, the first piston 28, the first moving rod 29, the clamping block 30, and the electric heating block 31 are reset. Subsequently, control the motor 8 to rotate forward, so that components such as the first sliding seat 11 can move upward. Then, by the opposite principle, components such as the column 17, the rotating rod 18, and the moving plate 12 are reset to release the fixation of the packaging bag, and then the packaging bag can be removed from the device. Thus, the packaging of the light bulb is completed.

[0048] The above is only a preferred embodiment of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention falls within the scope of protection required by the present invention.
