[0022] Specifically, the frame 1 is composed of a base box 11 connected with a first bracket 12 and a second bracket 13. The base box 11 is hollow inside to form an installation cavity. A water cooling mechanism 14 is arranged in the installation cavity. The water cooling mechanism 14 is composed of a water tank and a water pump. The first bracket 12, the second bracket 13, the lower pressure bar 3 and the fixed pre-pressure plate 5 are fixedly arranged on the upper end surface of the base box 11. The clamping cylinder 4 is arranged on the first bracket 12, and the pre-pressure cylinder 7 is arranged on the second bracket 13. An electrical box 15 is arranged on the upper end surface of the first bracket 12. The electrical box 15 is provided with electrical components such as a power switch, a power indicator light, a working indicator light, a sealing time adjustment display, and a cooling time adjustment display.

[0023] In the above embodiment, by arranging the water cooling mechanism 14 and the electrical box 15 in the base box 11 and on the first bracket 12 respectively, the water cooling sealing machine is made more compact as a whole, and the overall volume of the water cooling sealing machine is reduced, which is convenient for transportation when leaving the factory. When in use, the space occupied is small, and the use is more convenient. In addition, the reduction in the overall size controls the cost and improves the economic benefit. When performing the sealing operation, the bag mouth of the packaging bag is tightened so that it passes through the fixed pre-pressing plate 5 and the movable pre-pressing plate 6 and the lower pressure strip 3 and the upper pressure strip 2 in turn. The pre-pressing cylinder 7 drives the movable pre-pressing plate 6 to move downward and cooperates with the fixed pre-pressing plate 5 to press the bag of the packaging bag. The mouth of the packaging bag is pressed tightly. At this time, the person can manually release the packaging bag, and then the pressing cylinder 4 drives the upper pressing bar 2 to move downward, and cooperates with the heated lower pressing bar 3 to achieve the sealing of the packaging bag. During the sealing operation of the above-mentioned packaging bag, the bag mouth of the packaging bag is pre-pressed by the cooperation of the fixed pre-pressing plate 5 and the movable pre-pressing plate 6. In the subsequent sealing process, there is no need to manually tighten the bag mouth of the packaging bag, thereby avoiding the situation where the person's hand touches the heated lower pressing bar 3, improving the safety of the water-cooled sealing machine when in use, and by pre-pressing the bag mouth of the packaging bag, the bag mouth of the packaging bag can be made smoother when sealing, thereby improving the quality of sealing.

When the fixed pre-stressing plate 5 and the movable pre-stressing plate 6 cooperate to pre-stress the bag opening of the packaging bag, the fixed pre-stressing portion 51 and the movable pre-stressing portion 61 respectively contact with two surfaces of the bag opening of the packaging bag, and the contact area between the fixed pre-stressing plate 5 and the movable pre-stressing plate 6 and the packaging bag when they cooperate to pre-stress the bag opening of the packaging bag is increased through the action of the fixed pre-stressing portion 51 and the movable pre-stressing portion 61, thereby achieving a more stable pre-stressing effect and further ensuring the quality of the sealing.

[0025] Preferably, a cylinder strip 8 is fixedly connected to the output shaft of the clamping cylinder 4, and at least two connecting rods 21 are fixedly connected to the upper strip 2. The connecting rods 21 pass upward through the cylinder strip 8 and are screwed with limiting nuts 22. A number of springs 9 are arranged between the cylinder strip 8 and the upper strip 2. The springs 9 play a buffering role when the clamping cylinder 4 drives the cylinder strip 8 to drive the upper strip 2 and the lower strip 3 to cooperate for sealing, thereby ensuring the stability of the upper strip 2 and the lower strip 3 when they cooperate, thereby ensuring the quality of the sealing.

[0026] Preferably, a plurality of first limiting holes 81 matching the spring 9 are provided on the lower surface of the cylinder pressure strip 8, and a plurality of second limiting holes 23 matching the spring 9 and corresponding one-to-one to the plurality of first limiting holes 81 are provided on the upper surface of the upper pressure strip 2. The two ends of the spring 9 are respectively retained in the first limiting holes 81 and the second limiting holes 23. Through the action of the first limiting holes 81 and the second limiting holes 23, the spring 9 is more stably retained between the cylinder pressure strip 8 and the upper pressure strip 2 to play a buffering role.

[0027] Preferably, a handle 112 is fixedly connected to the left and right plates of the base box 11 respectively, and the handle 112 facilitates the transfer of the water-cooled sealing machine, thereby improving the convenience of the water-cooled sealing machine when in use.

[0028] Furthermore, a support plate 10 is arranged on the front side plate of the base box 11, and at least two longitudinal adjustment slots 111 are opened on the front side plate of the base box 11. A plurality of adjustment screws 101 passing through the adjustment slots 111 are passed through the support plate 10, and the adjustment screws 101 are threadedly connected with adjustment nuts 102 after passing through the adjustment slots 111.

[0029] In the above preferred embodiment, the support plate 10 provides support for the material in the packaging bag during the sealing operation, so that the packaging bag remains stable during sealing and the quality of the sealing is guaranteed. According to the amount of material in the packaging bag, the adjusting screw 101 can be slid in the adjusting groove 111 after loosening the adjusting nut 102, and the height of the support plate 10 on the base box 11 can be adjusted to match the sealing operation of packaging bags of different heights, which has better applicability.
