[0024] The specific implementation manner of the utility model will be described in detail in combination with the drawings and the preferred embodiments.

[0025] As shown in the drawings, Figs. 1-3 A water-moisturizing cream packaging bag sealing machine includes a support mechanism 1, a cam mechanism 2, a rebound mechanism 3, an upper head moving mechanism 4 and a lower head moving mechanism 5; wherein the support mechanism is used for supporting the whole set of mechanism, the support mechanism 1 includes a support frame

[0026] 11 and four side connecting plates 12, the four side connecting plates are divided into two groups, each group has two plates, and are respectively fixed on the upper side and the lower side of the support frame, and the side of each side connecting plate 12 is respectively provided with two first clamping wheels 13. The support frame of the support mechanism provides a stable support basis for the whole set of mechanism. The first clamping wheels on the side connecting plate and the second clamping wheels in the upper head moving mechanism are respectively clamped on the guide rod and rollingly cooperate with the guide rod, not only providing a stable guide action for the up-down movement of the guide rod, but also ensuring the stability of the upper head moving mechanism and the lower head moving mechanism during the movement process, and ensuring the stability and reliability of the whole work of the sealing machine.

[0027] The cam mechanism as a power source for driving the upper head moving mechanism 4 and the lower head moving mechanism 5 to move, the cam mechanism 2 includes a motor 21 and a cam 22, the motor is fixed on the support frame 11 through a motor support 23, the output end of the motor is connected with the cam to drive the cam to rotate. The motor in the cam mechanism starts to operate after the power is turned on, the motor is stably installed on the support frame through the motor support, the output end of the motor drives the cam to rotate, and the cam mechanism provides a power source for the whole sealing machine.

[0028] The continuous rotation of the cam is the core power of the subsequent series of component movements.

[0029] The rebound mechanism 3 is used for making the movement of the lower head moving mechanism more smooth, the rebound mechanism 3 includes a clamp plate 31, a first bearing 32, a first buffer spring 33 and a spring connecting plate 34, the spring connecting plate is fixed on the upper part of the support frame 11, the first buffer spring is arranged between the clamp plate and the spring connecting plate, the first bearing is installed on the lower part of the clamp plate, the first bearing is matched with the circumference of the cam, further, in order to improve the rebound effect, the first bearing is in close contact with the surface of the cam, pneumatic rods 35 are arranged on both sides of the first buffer spring respectively, when the cam rotates, the first bearing moves up and down to drive the spring connecting plate to move up and down by overcoming the resistance of the first buffer spring and the pneumatic rod.

[0030] The upper sealing head moving mechanism 4 is capable of moving up and down. The upper sealing head moving mechanism 4 includes an upper sealing head 41, an upper sealing head connecting plate 42, a first guide sleeve 43, a connecting rod 44, a moving plate 45, a second bearing 46, a side plate 47, a tension spring 48, and four second clamping wheels 49. The upper sealing head is fixed to the lower part of the upper sealing head connecting plate and is used for heat sealing the upper part of the packaging bag opening. The first guide sleeve is installed at both ends of the upper sealing head connecting plate. The upper part of the upper sealing head connecting plate is fixedly connected to the lower part of the connecting rod. The upper part of the connecting rod is fixedly connected to the lower part of the moving plate. Side plates are fixed to both sides of the moving plate, and two second clamping wheels are installed on the outer sides of each side plate. The upper part of the tension spring is fixedly connected to the lower part of the moving plate, and the lower part of the tension spring is connected to the upper part of the upper end cap connecting plate, ensuring that the upper end cap connecting plate always has an upward force. When the cam rotates, it cooperates with the second bearing to overcome the tension of the tension spring, causing the moving plate to move up and down. This, in turn, drives the upper end cap connecting plate and the upper end cap to move up and down via the connecting rod. The moving plate of the end cap moving mechanism has side plates fixed to both sides. The second clamping wheels on the outer sides of the side plates are clamped onto the guide rod and roll in cooperation with it. When the cam rotates, it interacts with the second bearing on the moving plate. Since one end of the tension spring is connected to the lower part of the moving plate and the other end is connected to the upper part of the upper end cap connecting plate, the tension spring always provides an upward tension to the upper end cap connecting plate. When the cam rotates and moves the second bearing upward, it overcomes the tension of the tension spring and drives the moving plate to move upward. The moving plate pulls the upper sealing head connecting plate and the upper sealing head upward through the connecting rod. Conversely, when the cam rotates and moves the second bearing downward, the upper sealing head moves downward under the action of gravity and the cam, thereby realizing the heating and sealing action of the upper sealing head on the upper part of the packaging bag opening.

[0031] The lower end cap moving mechanism 5 includes a lower end cap 51, a lower end cap connecting plate 52, a second guide sleeve 53, a second buffer spring 54, a lower connecting plate 55, and two guide rods 56. The lower parts of the two guide rods are respectively bolted to both ends of the lower connecting plate. The second buffer spring is sleeved on the guide rod. The second guide sleeve is respectively fixed to both ends of the lower end cap connecting plate and slides with the guide rod. The lower end cap is fixed to the lower end cap connecting plate, and the first guide sleeve slides with the two guide rods. The clamping plates of the spring mechanism are clamped at both ends to the guide rods. A first bearing installed at the lower part of the clamping plate is in circumferential engagement with a cam. When the cam rotates, it drives the first bearing to move up and down. The up and down movement of the first bearing causes the spring connecting plate to move up and down against the resistance of the first buffer spring and the pneumatic rod, thereby driving the clamping plate to move up and down. Since the clamping plate is fixed to the guide rod, the up and down movement of the clamping plate will drive the guide rod to move up and down. In the lower sealing head moving mechanism, the lower part of the guide rod is fixed to both ends of the lower connecting plate by bolts. The second buffer spring is sleeved on the guide rod, and the second guide sleeves at both ends of the lower sealing head connecting plate slide with the guide rod. The lower sealing head is fixed on the lower sealing head connecting plate. Therefore, the up and down movement of the guide rod will drive the lower sealing head to move up and down, realizing the sealing action of the lower part of the packaging bag opening.

[0032] Each set of first and second clamping wheels is clamped on the guide rod and rolls with it. The two ends of the clamping plate 31 are clamped on the guide rod and are fixed to the guide rod. When the clamping plate moves up and down, it will simultaneously drive the guide rod to move up and down. Under the smooth guidance of the first clamping wheel, the lower sealing head moves up and down. The lower sealing head is equipped with a second buffer spring, so when the upper sealing head and the lower sealing head are combined, there will be a buffer for the packaging opening.

[0033] The first buffer spring in the rebound mechanism works in conjunction with the pneumatic rods on both sides to make the movement of the lower sealing head smoother and more stable. During the up-and-down movement of the first bearing driven by the cam, the first buffer spring acts as a buffer, preventing excessive movement; the pneumatic rods further enhance the rebound effect, ensuring that the clamping plate stably drives the guide rod up and down. The second buffer spring in the lower sealing head moving mechanism acts as a buffer when the upper and lower sealing heads combine to seal the packaging opening, reducing the impact on the packaging bag, protecting the bag, and also improving the sealing quality.

[0034] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
