At the same time, a heat sealing assembly 6 is also provided. The heat sealing assembly 6 also penetrates the fixing frame 1 and extends to the other side. By driving the half gear 53 to rotate by the driving motor 51, the driving gear 54 can be indirectly driven to reciprocate by meshing with the half gear 53. When block 73 rotates a certain angle, connecting rod 2 75 and connecting rod 1 74 will drive active block 1 76 and active block 2 77 to move, thereby indirectly making heat sealing block 1 66 and heat sealing block 2 67 approach each other to extrude and heat seal the packaging bag.

[0035] The driving assembly 5 in this solution is mainly used to drive the device to work. The driving motor 51 is fixed on the top of the mounting plate 2, wherein the output end of the driving motor 51 passes through the mounting plate 2 and is also fixed with a rotating shaft 52.

[0036] Optionally, in some embodiments, see Figures 1-4 The transmission assembly 7 also includes a rotating shaft 71, a reciprocating block 73 is fixedly mounted on the outer end of the rotating shaft 71, and both ends of the rotating shaft 71 respectively pass through the mounting plate 2 3 and the mounting plate 3 4, and the rotating shaft 71 is rotatably mounted between the mounting plate 2 3 and the mounting plate 3 4, and a return torsion spring 72 is installed at both ends of the rotating shaft 71, and one end of the two return torsion springs 72 is respectively mounted on the outer ends of the mounting plate 2 3 and the mounting plate 3 4.

[0037] The driving gear 54 is fixedly mounted on the outer end of the rotating shaft 71. The driving gear 54 drives the rotating shaft 71 to rotate by meshing with the half gear 53. The connecting rod 1 74 is rotated away from the end of the reciprocating block 73 and is connected to the active block 2 77. The connecting rod 2 75 is rotated away from the end of the reciprocating block 73 and is connected to the active block 1 76. The active block 1 76 and the active block 2 77 move in opposite directions.

[0038] The heat sealing assembly 6 includes a passive plate 61 and two sliding sleeves 63. The two sliding sleeves 63 are fixedly installed on the outer end of the fixed frame 1, and the two sliding sleeves 63 pass through the fixed frame 1. The outer end of the passive plate 61 is fixedly connected to two symmetrically distributed push rods 62. The two push rods 62 respectively pass through the two sliding sleeves 63, and the push rods 62 are slidably connected to the sliding sleeves 63.

[0039] The ends of the two push rods 62 away from the passive plate 61 are fixedly connected to the active block 2 77, and the outer end of the passive plate 61 is fixedly installed with a heat sealing block 66.

[0040] The heat sealing assembly 6 also includes two sliding sleeves 2 64, which are fixedly mounted on the outer ends of the fixing frame 1, and the two sliding sleeves 2 64 both penetrate the fixing frame 1, and the inner sides of the two sliding sleeves 2 64 are slidably connected with push rods 2 65, one end of the push rod 2 65 is fixedly connected to the active block 1 76, and the other end of the push rod 2 65 is fixedly connected to the passive block 2 68, and the outer end of the passive block 2 68 is fixedly connected to the heat sealing block 2 67, and heating mechanisms are provided inside the heat sealing block 2 67 and the heat sealing block 1 66.

[0041] The transmission assembly 7 in this scheme is mainly used to transmit the power of the driving assembly 5 to drive the heat sealing assembly 6 to work. The rotating shaft 71 is rotatably mounted between the mounting plate 2 3 and the mounting plate 3 4 through the bearing. At the same time, the two ends of the rotating shaft 71 are respectively installed with a reset torsion spring 72. One end of the reset torsion spring 72 is clamped on the rotating shaft 71, and the other end is clamped on the mounting plate 2 3 or the mounting plate 3 4. The rotating shaft 71 can be reset by the torsion of the reset torsion spring 72 itself. The reciprocating block 73 is fixed, and the reciprocating block 73 is arranged in a shuttle shape. The two ends are respectively connected to the connecting rod 1 74 and the connecting rod 2 75, and the other ends of the connecting rod 1 74 and the connecting rod 2 75 are connected to the active block 2 77 and the active block 1 76. The outer end of the active block 2 77 is fixed with two push rods 1 62, and two sliding sleeves 1 63 are fixed on the fixed frame 1. The two sliding sleeves 1 63 are just penetrated by the two push rods 1 62, so that the push rod 1 62 can slide back and forth in the sliding sleeve 1 63. At the outer end of the fixed frame 1, two sliding sleeves 2 64 are also fixed. These two sliding sleeves 2 64 are used to allow two push rods 2 65 to pass through and slide back and forth. At the same time, one end of the two push rods 2 65 is fixed on the active block 1 76. It is worth mentioning that the sliding sleeve 1 63 and the sliding sleeve 2 64 both pass through the fixed frame 1 and are fixed in the middle. The other ends of the two push rods 1 62 are fixed on the passive plate 1 61, and the other ends of the two push rods 2 65 are fixed on the passive block 2 68, a heat sealing block 1 66 is fixed on the passive plate 1 61, and a heat sealing block 2 67 is fixed on the passive block 2 68. The heat sealing block 2 67 and the heat sealing block 1 66 are mainly used for heat sealing. A heating mechanism is provided inside the heat sealing block 2 67 and the passive block 2 68. The heating mechanism is mainly composed of a heat pipe. The heat pipe heats the heat sealing block 1 66 and the heat sealing block 2 67 inside the heat sealing block 1. At the same time, the outer ends of the heat sealing block 1 66 and the heat sealing block 2 67 are also provided with evenly distributed raised strips.

[0042] When the driving motor 51 rotates, the rotating shaft 52 drives the half gear 53 to rotate. When the toothed side of the half gear 53 rotates to engage with the driving gear 54, the driving gear 54 drives the rotating shaft 71 to rotate. The rotating rotating shaft 71 will first twist the return torsion springs 72 at both ends, and the reciprocating block 73 will also rotate with it. Then the connecting rod 1 74 and the connecting rod 2 75 at both ends of the reciprocating block 73 will rotate, thereby forcing the active block 2 77 and the active block 1 76 connected to it to move away from each other. At this time, the active block 2 77 will cause the push rod 1 62 to pull the passive plate 1 61, so that the heat sealing block 1 66 fixed on the passive plate 1 61 moves toward the heat sealing block 2 67. At the same time, the active block 1 76 will also be driven by the connecting rod 2 75 to push Push rod 2 65, push rod 2 65 uses the same method to make passive block 2 68 drive heat sealing block 2 67 to move toward heat sealing block 1 66. At this time, the packaging bag located between heat sealing block 1 66 and heat sealing block 2 67 will be squeezed and heat-sealed, and the continuous rotation of the half gear 53 will enable some of its teeth to complete the engagement with the drive gear 54. The part without teeth cannot drive the drive gear 54. At this time, the torsion of the reset torsion spring 72 can make the rotating shaft 71 drive the reciprocating block 73 to reset, and heat sealing block 1 66 and heat sealing block 2 67 will also reset. Through the continuous rotation of the half gear 53, heat sealing block 1 66 and heat sealing block 2 67 can continue to reciprocate to heat-seal the packaging bag, which can achieve high-speed continuous production and greatly improve production efficiency.

[0043] Working principle: The device in this scheme mainly drives the transmission component 7 through the driving component 5, so that it drives the heat sealing component 6 to perform reciprocating motion to perform continuous heat sealing. The driving motor 51 is fixed to the top of the mounting plate 2. The output end of the driving motor 51 is fixed to the rotating shaft 52, and the outer end of the rotating shaft 52 is fixed to the half gear 53. The two ends of the rotating shaft 71 are respectively installed with a reset torsion spring 72. The torsion of the reset torsion spring 72 can reset the rotating shaft 71. The reciprocating block 73 is arranged in a shuttle shape, and is connected to the connecting rod 1 74 and the connecting rod 2 75 at both ends. When the driving motor 51 rotates, the half gear 5 When the toothed side rotates to engage with the driving gear 54, the driving gear 54 indirectly drives the reciprocating block 73 to rotate, and the connecting rod 1 74 and the connecting rod 2 75 rotate, thereby forcing the active block 2 77 and the active block 1 76, which are rotatably connected thereto, to move away from each other, so that the heat sealing block 1 66 and the heat sealing block 2 67 move closer to each other, squeezing the packaging bag to perform heat sealing. Then, the rotating shaft 71 drives the reciprocating block 73 to return to its original position, and the heat sealing block 1 66 and the heat sealing block 2 67 also return to their original position. Through the continuous rotation of the half gear 53, the heat sealing block 1 66 and the heat sealing block 2 67 can continue to reciprocate to heat seal the packaging bag.
