Abstract
The utility model discloses a vacuum packaging machine, including fuselage, cover, heat-seal subassembly and control circuit board, the heat-seal subassembly includes two above heater, sets up at fuselage, cover to closing the portion, controls it through control circuit board and switches on with the power successively. The utility model discloses a control circuit control heat-seal subassembly successively switches on with the power to improve vacuum packaging machine's life, and effectively promote the performance of sealing to the plastic bag.
Description
Technical Field
The utility model relates to the technical field of packaging machines, specifically a vacuum packaging machine.
Background
The vacuum packaging machine can vacuumize and seal the vacuum packaging bag containing food, so that the food in the vacuum packaging bag can be stored for a long time, and the vacuum packaging machine is increasingly widely applied. The sealing part of the existing vacuum packaging machine is mostly a single heating wire or two heating wires, when the sealing of the vacuum packaging machine adopts the single heating wire, the heating wire is directly arranged at the sealing part, when the plastic bag is compressed, the single heating wire fixed at the sealing part of the vacuum packaging machine is heated, so that the plastic bag is vacuumized and fused for sealing, and finally the process of sealing the plastic bag in vacuum is finished; when the sealing of the vacuum packaging machine adopts two heating wires, when the two heating wires work simultaneously, the whole total power of the vacuum packaging machine needs the control circuit to provide larger current, the large current in the control circuit loop flows through the electronic components of the circuit, so that the temperature inside the electronic components rises sharply, the electronic components often work in a high-temperature state, fatigue easily occurs, the service life of the electronic components is shortened, the electronic components are burned out seriously, the vacuum packaging machine is easy to break down, and the sealing performance of the vacuum packaging machine is seriously influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a vacuum packaging machine switches on with the power through control circuit control heat-seal subassembly is earlier to improve vacuum packaging machine's life, ensure the performance that vacuum packaging machine sealed to the plastic bag.
A vacuum packaging machine, including fuselage, cover, heat-seal subassembly and control circuit board, the heat-seal subassembly includes two above heater, sets up at fuselage, cover to closing the portion, controls it successively through control circuit board and switches on with the power.
A vacuum packaging machine, successively switch on with the power through control circuit board control heat-seal subassembly, avoided when the whole heat-seal subassembly switches on and generates heat, its whole total power needs control circuit to provide great electric current, the electronic components of this circuit is flowed through to the heavy current that appears in the control circuit board return circuit, cause the inside temperature of electronic components to rise sharply, make electronic components often work under high temperature state, appear tiredly easily, shorten its life, then electronic components is burnt out seriously, thereby cause vacuum packaging machine to produce the trouble easily, seriously influence its sealing performance.
Description of the drawings.
Fig. 1 is a schematic view of the structure of the body of the present invention;
FIG. 2 is a schematic view of the vacuum packaging machine of the present invention;
fig. 3 is the principle schematic diagram of the control circuit controlling the heat sealing assembly of the utility model.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the vacuum packaging machine comprises a machine body 1, a machine cover 3, a heat sealing assembly 4 and a control circuit board, and is characterized in that the heat sealing assembly 4 comprises more than two heating wires and is arranged at the butt joint part of the machine body 1 and the machine cover 3, and the control circuit board controls the heat sealing assembly to be sequentially conducted with a power supply.
Control heat-seal assembly 4 through control circuit control successively switches on with the power, avoided when heat-seal assembly 4 wholly switches on and generates heat, its whole total power needs control circuit board to provide great electric current, the electronic components of this circuit is flowed through to the heavy current that appears in the control circuit board return circuit, cause the inside temperature of electronic components to rise sharply, make electronic components often work under high temperature state, appear tired easily, shorten its life, then electronic components is burnt out seriously, thereby cause vacuum packaging machine to break down easily, seriously influence sealing performance.
In the embodiment, the heat sealing assembly 4 is provided with two heating wires, and the two heating wires are respectively arranged on the machine body 1 of the involution part of the machine body 1 and the machine cover 3; the two heating wires are respectively arranged on the machine body 1 and the machine cover 3 of the machine cover 3 involution part. One of the heating wires can also be arranged on the machine body 1 of the vacuum packaging machine, the other heating wire is arranged on the machine cover 3, and the two heating wires are just sealed with the plastic bag into two sealing openings which are parallel and have proper distance when the machine body 1 and the machine cover 3 are closed.
The outer surfaces of the two heating wires are wrapped with insulating tapes, so that the surfaces of the plastic bags are prevented from being scratched when the two heating wires are used for connecting, fusing and sealing the plastic bags.
As shown in fig. 3, the heat sealing assembly 4 includes two heating wires, the two heating wires are electrically connected to respective pads 11 of the circuit board 7, and the control chip 8 on the key board 6 is electrically connected to the circuit board 7 through the data line 10 to control the two heating wires to be sequentially conducted with the power supply, so that the control circuit of the vacuum packaging machine always keeps the single heating wire load working and can achieve the double heating wire effect.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
