Technical Field
[0001] The invention relates to the technical field of sealing machines, and in particular to a self-cutting hand-pressure sealing machine with a temperature control function. Background Art
[0002] The hand-pressed sealing machine is a machine that seals containers filled with packaging materials. After the product is loaded into the packaging container, in order to keep the product sealed and preserved, maintain product quality, and avoid product loss, the packaging container needs to be sealed. This operation is to turn on the power, control the digital buttons to adjust the temperature, put the product on the machine, and gently press the hand to complete the sealing machine. The principle is to use the heating wire to seal the bag. Put the bag mouth on the machine and gently press it 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 make the bag mouth flat; The existing hand-pressed sealing machine has no good heat dissipation effect when used for a long time. The plastic shell of the machine will also burn and deform. At the same time, during the sealing process, the position is adjusted manually, which makes it impossible to adjust the position in time during the sealing and squeezing process, resulting in position deviation. In order to prevent air from entering and having a bad effect on the product. Summary of the invention

The limiting hole is slidably connected to the connecting rod, and the circular plate is slidably connected to the circular hole. The square plate drives the connecting rod to slide inside the limiting hole, so that the circular plate slides inside the circular hole, and then the air between the heating strip and the high-temperature cloth is connected to the outside world through the circular hole, the air outlet and the limiting hole, thereby improving the heat dissipation effect, so as to prevent the machine shell of the plastic shell from burning and deforming after the hand pressure sealing machine has been sealing continuously for a long time.

In the initial state, the pressure arm is away from the base, the magnetism between the magnetic block and the magnetic ball is the same, and the elastic rope is in a taut state. Under the action of the fixed rod's own gravity, the mutual repulsion between the magnetic block and the magnetic ball, and the elastic force of the elastic rope, the fixed rod is in a balanced state, so that the fixed rod has a certain inclination angle.

[0010] The beneficial effects of the present invention are as follows: 1. The present invention sets a base, and the square plate drives the connecting rod to slide inside the limiting hole, so that the circular plate slides inside the circular hole, and then the air between the heating strip and the high-temperature cloth is connected with the outside through the circular hole, the air outlet and the limiting hole, thereby improving the heat dissipation effect, so that when the hand pressure sealing machine is continuously sealed for a long time, the machine shell of the plastic shell is prevented from burning and deforming.
[0011] 2. The present invention sets a limit assembly. When the fixing rod is rotated to a horizontal position, the fixing rod is located inside the annular groove, and the outer wall of the fixing rod is in close contact with the bag. The bag is fixed by the fixing rod and the fixing groove, so that the bag does not shift during the sealing process. At the same time, the positioning strip is in contact with the annular groove.

[0012] 3. The present invention provides a handle so that people can hold the handle to perform the sealing work, so that they can press better and avoid hand slippage during pressing, which causes the pressing arm to directly rebound to end the work, thereby resulting in incomplete sealing and poor sealing effect, while avoiding accidental injuries to people.
[0013] 4. The present invention sets a smoothing component so that the pressure arm rotates around the rotating shaft, so that the roller of the fixed rod contacts the surface of the bag on the fixed groove, and the pressure arm continues to move downward, and the fixed rod rotates around the fixed plate. Under the mutual repulsive force between the magnetic block and the magnetic ball, the roller applies pressure to the surface of the bag while rolling, thereby smoothing the bag.
[0014] 5. The present invention provides rollers. When placing the bags, wrinkles are likely to appear on the bags. However, during the sealing and squeezing process, the position cannot be adjusted manually, resulting in poor sealing quality. The rollers can be provided to smooth the bags.
[0015] 6. The present invention sets an elastic component. When a person holds the handle and presses the straight rod with his thumb, the positioning rod rotates inside the rotating groove with the rotating rod as the center. Then, the end of the positioning rod close to the limit block contacts the contact plate through the through hole and squeezes the contact plate. The spring is compressed, thereby preventing the person from having insufficient strength to press the pressure arm after working for a long time, and the pressure arm will not rebound immediately, causing injury to the person.
