[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 2As shown, a heat sealing device for producing medical packaging bags includes a feeding rack 1. A conveyor belt 5 is provided on the inner side of the feeding rack 1. The staff places the packaging bag with the bag opening facing inward on the conveyor belt 5, connects the device to the external air compressor, and controls the roller 4 and the conveyor belt 5 to rotate through the provided first motor 2 to convey the packaging bag. The packaging bag is sensed by the provided sensor 23. When the packaging bag is conveyed to the bottom of the fixed bracket 6, the sensor 23 senses the position of the packaging bag. At this time, the first motor 2 stops working and the first cylinder 7 is started. The protective cover 10 is controlled to move up and down by the provided first cylinder 7. The first heating block 11 is driven to move up and down, and the second cylinder 20 is started at the same time. The second cylinder 20 is used to control the second heating block 18 to move up and down, so that the second heating block 18 is fitted with the first heating block 11, thereby heat-sealing the packaging bag. The first heating block 11 is protected by the protective cover 10, and the first heating block 11 and the telescopic rod 12 are used to buffer the first heating block 11 to prevent the packaging bag from being squeezed due to excessive fitting. The first wiring terminal 14 and the second wiring terminal 19 are provided to facilitate the staff to connect the first heating block 11 and the second heating block 18 to enable them to be powered on for heating.

[0023] like Figure 3-Figure 4 As shown, a heat sealing device for producing medical packaging bags. When the heat sealing is completed, the protective cover 10 and the first heating block 11 are controlled to move upward by the first cylinder 7, and the second heating block 18 is controlled to move downward by the second cylinder 20 to separate the two. At this time, the first motor 2 and the second motor 3 are started, and the two sets of conveyor belts 5 are controlled to rotate by the first motor 2 and the second motor 3 to convey the heat-sealed packaging bags. Due to the large volume of the packaging bags, they will not fall into the gap between the two sets of conveyor belts 5 during the transportation process.

[0024] like Figure 5 As shown, a heat sealing device for producing medical packaging bags facilitates workers to adjust the position of the sensor 23 according to the size of the packaging bag through the provided slide groove 21 and T-block 25. After sliding it to the appropriate position, tighten the fixing screw 24 and fix the sensor 23 through the provided T-block 25, which greatly reduces the labor intensity of the workers, facilitates the workers' operation, improves the practicality of the equipment, reduces the investment cost, and improves the market competitiveness.
