[0001] The invention relates to the technical field of sealing packaging, and more specifically to a hand-pressure sealing machine. Background Art

[0002] The sealing machine is a machine that seals the container filled with packaging. The hand-pressed sealing machine is a small household sealing machine. The principle is to use a heating wire to seal the bag. Put the bag mouth on the machine and press it gently with your hand. The operation is simple and convenient. The hand-pressed sealing machine includes a base and a handle. The base is equipped with a heating wire. When using it, the person manually places the bag mouth on the upper surface of the base. This process requires two hands to operate to flatten the bag mouth. However, during the sealing process, one hand has to leave the bag mouth to press the handle. In this process, the bag mouth may shift, thus affecting the sealing effect of the bag. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a hand pressure sealing machine, during the sealing process of the hand pressure sealing machine, the bag mouth is not easy to shift and the sealing effect is better.

With this structure, when the clamping plate is pressed to leave the anti-scalding plate, one side of the bag opening of the packaging bag is inserted between the clamping plate and the anti-scalding plate, and then the pressing component is released, so that the clamping plate clamps the bag opening on the anti-scalding plate, which is very convenient to use.

[0011] As an improvement, the fixing device includes a clamping plate and a driver, and a gap is left between the clamping plate and the anti-scalding plate; when the clamping plate moves downward under the action of an external force, the driver can lock the position of the clamping plate; after the sealing is completed, the driver can drive the clamping plate to reset. With this structure, when sealing, one side of the bag opening can be inserted into the gap, and then the clamping plate is pressed downward to clamp the bag opening between the clamping plate and the anti-scalding plate, and the position of the clamping plate is locked by the driver. After the sealing is completed, the driver can drive the clamping plate to reset and take out the bag, which is very convenient to use.

[0055] A connecting member 4-18 is connected to the inner wall of the base 4-1, and the driving member 4-15 can be movably engaged with the connecting member 4-18 up and down. The upper end of the driving member 4-15 is connected to the lower surface of the heating plate 4-401 of the heating component 4-4 close to the clamping plate 4-6. One end of the heating plate 4-401 is connected to the base 4-1, and the other end of the heating plate 4-401 (i.e., the end close to the clamping plate 4-6) can move up and down. A second return elastic member 4-12 is provided between the heating plate 4-401 and the connecting member 4-18. The second return elastic member 4-12 applies a force to the heating plate 4-401 to move away from the rotating shaft 4-14. The lower end of the driving member 4-15 abuts against the upper side of the other end of the paddle 4-13.

[0056] When the hand-pressed sealing machine of the present invention is working, one side of the bag opening is inserted into the space between the clamping part 4-601 and the anti-scalding plate 4-5, and then the clamping part 4-601 is pressed downward, and the connecting column and the rack 4-9 at the lower end thereof will move downward together. During the process of the rack 4-9 descending, the gear 4-10 will rotate, and the gear 4-10 will drive the rotating shaft 4-14 and the ratchet 4-16 to rotate together; when the ratchet 4-16 rotates, one end of the paddle 4-13 will abut against the corresponding bevel teeth to limit the ratchet 4-16. When the clamping plate 4-6 descends to a certain position, the bag opening will be clamped between the clamping part 4-601 and the anti-scalding plate 4-5. Then hold the other side of the bag opening with one hand, and press the handle 4-2 with the other hand. When the handle 4-2 is pressed down, one end of the heating plate 4-401 will also move downward to press the driving member downward. The driving member 4-15 moves downward to press the other end of the paddle 4-13. The end of the paddle 4-13 that is against the bevel teeth will tilt upward. When the paddle 4-13 is separated from the bevel teeth, the limit of the ratchet 4-16 is solved. After releasing the handle 4-2, the sealing is completed. Under the action of the first return elastic member 4-8, the splint 4-6 will return upward, and the rack 4-9 will drive the gear 4-10, the shaft 4-14 and the ratchet 4-16 to rotate in the opposite direction until one end of the paddle 4-13 is against the bevel teeth of the ratchet 4-16 again. The first return elastic member 4-8 and the second return elastic member 4-12 are both return springs.

Claims

1. A hand-pressed sealing machine, comprising a base and a handle, wherein a heating component is provided on the base; characterized in that: The base is also provided with a fixer, which is used to fix the bag opening when the bag is sealed; The base is also provided with an anti-scalding plate, which surrounds the heating component; the fixer is arranged on the anti-scalding plate; A through hole is provided in the middle of the anti-scalding plate, and the heating component is arranged in the through hole; the fixer is located on one side of the heating component; The fixing device includes a clamping plate and a driver, and a gap is left between the clamping plate and the anti-scalding plate; when the clamping plate moves downward under the action of an external force, the driver can lock the position of the clamping plate; after the sealing is completed, the driver can drive the clamping plate to reset; The driver comprises a rack, a tooth-pressing member and a toggle assembly; the rack is arranged on the clamping plate; the tooth-pressing member comprises a pressing member, the tooth-pressing member is movably connected in the base and the end of the tooth-pressing member is against the tooth groove of the rack; The toggle assembly is connected to the tooth-pressing member, and the toggle assembly includes a rotating shaft and a paddle. The pressing member drives the rotating shaft to rotate, and the rotating shaft drives the paddle to rotate.
