[0002] A heat sealing machine is a device that uses electrical energy to convert into heat energy to heat seal the opening of a packaging bag. Heat sealing machines are widely used in enterprise production processes. After producing products, enterprises place the products inside packaging bags and place the opening of the packaging bags on the heat sealing machine to heat seal the opening of the packaging bags.

[0003] When using existing heat sealing machines, personnel need to place the bag opening onto the heat sealing block. If personnel remove their hands after placing the bag opening on the heat sealing block during the heat sealing process, the bag opening cannot be kept taut. After heat sealing, wrinkles may appear at the bag opening, affecting the aesthetics and sealing performance. If the hands are not removed, personnel may accidentally injure their hands, posing a certain safety hazard. Therefore, this utility model provides a heat sealing machine. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a heat sealing machine that solves the problem that when using the heat sealing machine, if the person places the bag opening on the heat sealing block and then removes their hands, the bag opening cannot be kept tight, and wrinkles may appear at the bag opening after heat sealing, affecting the aesthetics and sealing performance. If the hands are not removed, the person's hands may be accidentally injured, posing a certain safety hazard.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A heat sealing machine includes a heat sealing machine body, wherein a heat sealing port is provided on the front side of the heat sealing machine body, and a heat sealing block is provided at both the inner bottom end and the inner top end of the heat sealing port;

[0009] Connecting blocks are fixedly connected to both sides of the heat seal. A dovetail groove is formed on the upper surface of the connecting block. A lower clamping block is provided on the upper surface of the connecting block. A dovetail block is fixedly connected to the lower end of the lower clamping block. The lower clamping block and the connecting block with the dovetail groove are slidably connected through the dovetail block. An upper clamping block is hinged to one side of the lower clamping block. A first connecting block is fixedly connected to both sides of the lower clamping block and the upper clamping block.

[0010] Furthermore, a weak magnetic layer is provided on the lower surface of the upper clamping block, and the upper clamping block is attracted to the lower clamping block through the weak magnetic layer.

[0011] Furthermore, a beveled block is fixedly connected to one side of both the lower clamping block and the upper clamping block, and a second connecting block is fixedly connected to the upper surface of the heat sealing machine body. A top block is movably connected through the upper end of the second connecting block, and one end of the top block corresponds to the beveled block.

[0012] Furthermore, a pair of limiting blocks are fixedly connected to the upper end of the top block, and the pair of limiting blocks are distributed on both sides of the second connecting block.

[0013] Furthermore, a reinforcing column is fixedly connected to one end of the connecting block, and one end of the reinforcing column is fixed to the main body of the heat sealing machine.

[0014] 3. Beneficial Effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) In this scheme, after the bag opening is placed on the upper surface of the lower clamping block, the upper clamping block is rotated. Under the clamping of the upper and lower clamping blocks, the bag opening will be clamped. Then, the personnel hold the connecting blocks at both ends with their hands and move them to send the bag opening onto the heat sealing block. This allows the personnel's hands to be kept as far away from the heat sealing block in the heat sealing machine as possible, thereby reducing safety hazards.

[0017] (2) The upper clamping block of this solution is provided with a weak magnetic layer. Through the weak magnetic layer, the upper clamping block can be attracted to the lower clamping block. Based on the slight attraction between the upper and lower clamping blocks, when the bag opening is wrinkled, the personnel can flatten the bag opening. The flattened bag opening can be kept under the attraction and clamping and is not easy to restore. Then, the bag opening can be sealed, which can greatly reduce the possibility of wrinkles appearing when sealing the bag opening and improve the aesthetics and sealing performance of the seal.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Example

[0027] like Figure 1-5 As shown, a heat sealing machine includes a heat sealing machine body 1, a heat sealing port 101 is provided on the front side of the heat sealing machine body 1, and heat sealing blocks 102 are provided at the inner bottom end and the inner top end of the heat sealing port 101.

[0028] Connecting blocks 2 are fixedly connected to both sides of the heat seal. A dovetail groove 201 is provided on the upper surface of the connecting block 2. A lower clamping block 3 is provided on the upper surface of the connecting block 2. A dovetail block 301 is fixedly connected to the lower end of the lower clamping block 3. The lower clamping block 3 and the connecting block 2 with the dovetail groove 201 are slidably connected through the dovetail block 301. An upper clamping block 4 is hinged to one side of the lower clamping block 3. A first connecting block 5 is fixedly connected to both sides of the lower clamping block 3 and the upper clamping block 4.

[0029] When in use, place the bag opening on the upper surface of the lower clamping block 3, then rotate the upper clamping block 4. Under the clamping of the upper clamping block 4 and the lower clamping block 3, the bag opening will be clamped. Then, the person can pinch the first connecting blocks 5 at both ends and move them to send the bag opening onto the heat sealing block 102. This allows the person's hands to be kept as far away from the heat sealing block 102 in the heat sealing machine as possible, thereby reducing safety hazards.

[0030] The heat sealing machine body 1 is specifically model GHS-03 heat sealing machine. In this heat sealing machine, the heat sealing block 102 at the top inner end of the heat sealing opening 101 can move downwards, so that the bag opening is placed flat on the heat sealing block 102 at the bottom inner end. After the heat sealing block 102 at the top inner end moves downwards, it comes into contact with the heat sealing block 102 at the bottom inner end, thereby achieving heat sealing of the bag opening. The specific working principle of the heat sealing machine body 1 is existing technology and will not be described in detail here.

[0031] like Figure 4-5 As shown, a weak magnetic layer 401 is provided on the lower surface of the upper clamping block 4, and the upper clamping block 4 is attracted to the lower clamping block 3 through the weak magnetic layer 401.

[0032] In use, the upper clamping block 4 can be attracted to the lower clamping block 3 through the weak magnetic layer 401. Based on the slight attraction between the upper clamping block 4 and the lower clamping block 3, when wrinkles appear at the bag opening, the person can flatten the bag opening. The flattened bag opening can be held in place by the attraction and is not easy to restore. Then, the bag can be sealed, which can greatly reduce the possibility of wrinkles appearing at the bag opening when sealing, and improve the aesthetics and sealing performance of the seal.

[0033] like Figure 1-2 As shown, a beveled block 6 is fixedly connected to one side of both the lower clamping block 3 and the upper clamping block 4. A second connecting block 7 is fixedly connected to the upper surface of the heat sealing machine body 1. A top block 8 is movably connected through the upper end of the second connecting block 7. One end of the top block 8 corresponds to the beveled block 6.

[0034] When in use, move the top block 8. One end of the top block 8 will be pushed between the inclined blocks 6, which can force the lower clamping block 3 and the upper clamping block 4, which are attracted to each other, to separate, making it convenient for personnel to open and rotate the upper clamping block 4.

[0035] like Figure 2 As shown, a pair of limiting blocks 801 are fixedly connected to the upper end of the top block 8, and the pair of limiting blocks 801 are distributed on both sides of the second connecting block 7.

[0036] When in use, the limiting block 801 can prevent the top block 8 from falling off the second connecting block 7 to avoid loss.

[0037] like Figure 1 As shown, a reinforcing column 202 is fixedly connected to one end of the connecting block 2, and one end of the reinforcing column 202 is fixed to the heat sealing machine body 1.

[0038] In use, one end of the connecting block 2 is fixed to the heat sealing machine body 1, and the reinforcing column 202 can reinforce the other end of the connecting block 2, thereby greatly improving the stability of the connecting block 2.

[0039] In summary, the specific working process of this solution is as follows: After placing the bag opening on the upper surface of the lower clamping block 3, rotate the upper clamping block 4. Under the clamping of the upper clamping block 4 and the lower clamping block 3, the bag opening will be clamped. Then, the personnel hold the first connecting blocks 5 at both ends with their hands and move them to send the bag opening onto the heat sealing block 102. This allows the personnel's hands to be kept as far away from the heat sealing block 102 in the heat sealing machine as possible, thereby reducing safety hazards.

[0040] The upper clamping block 4 is provided with a weak magnetic layer 401. Through the weak magnetic layer 401, the upper clamping block 4 can be attracted to the lower clamping block 3. Based on the slight attraction between the upper clamping block 4 and the lower clamping block 3, when the bag opening is wrinkled, the person can flatten the bag opening. The flattened bag opening can be held in place by the attraction and is not easy to restore. Then, the bag can be sealed. This can greatly reduce the possibility of wrinkles appearing when sealing the bag opening and improve the aesthetics and sealing performance of the seal.

[0041] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
