[0036] The utility model will be further explained in detail in combination with the drawings and specific embodiments of the specification.
[0037] Referring to the drawings Figure 1 to the drawings Figure 4 It is shown that the embodiment provides a heat sealing knife 10, which comprises a housing 100, a sealing knife 200, a transformer 700, a power plug 600, a pair of circuit boards 400 and a pair of conductive plates 300.
[0038] The power plug 600 is arranged at the bottom end of the housing 100, and an external power supply provides power for the transformer 700 in the interior of the housing 100 through the power plug 600. The transformer 700 is installed in the inner cavity of the housing 100, and the transformer 700 is used to convert the low voltage input from the outside into high voltage and output the converted high voltage to the sealing knife 200, so that the sealing knife 200 is rapidly heated in a short time.
[0039] Referring to the drawings Figure 1 and drawings Figure 3 It is shown that the sealing knife 200 is provided with a mounting hole, and a temperature sensor 130 is installed in the mounting hole. The temperature sensor 130 is used to detect the temperature of the sealing knife 200 in real time.
[0040] Referring to the drawings Figure 3 to the drawings Figure 5As shown, in the embodiment, the mounting of the transformer 700 in the inner cavity of the shell 100 is performed by the transformer mounting seat 120 provided. Specifically, the transformer mounting seat 120 comprises a pair of clamping plates 121 and a plurality of locking columns 122, the pair of clamping plates 121 are arranged vertically and in parallel in the inner cavity of the shell 100, an installation cavity is formed between the pair of clamping plates 121, and the plurality of locking columns 122 are connected at the edges of the pair of clamping plates 121 in the circumferential direction, the locking columns 122 are fixedly installed on the inner wall of the shell 100, and the transformer 700 is installed in the installation cavity.
[0041] Referring to the accompanying drawings Figure 5 As shown, since the plurality of locking columns 122 are connected on the outer edges of the pair of clamping plates 121 in the circumferential direction, the locking columns 122 are provided to block the transformer 700 placed in the installation cavity, preventing the transformer 700 from sliding out of the installation cavity. In addition, since the locking columns 122 are arranged at intervals, there is a large gap between the adjacent two locking columns 122, so that the heat generated by the transformer 700 during operation can be dissipated outward through the above-mentioned gap.
[0042] Referring to the accompanying drawings Figure 4 and the accompanying drawings Figure 5 As shown, opposite ends of the locking column 122 are respectively formed with screw holes 123, and when the locking column 122 is locked on the shell 100, a screw can be screwed from the outside of the shell 100, so that the screw passes through the shell 100 (an installation hole is formed at the corresponding position of the shell 100) and is screwed into the screw hole 123 on the locking column 122, thereby fixing the locking column 122 on the shell 100.
[0043] Referring to the accompanying drawings Figure 1 to the accompanying drawings Figure 3 As shown, in the embodiment, a pair of circuit boards 400 are symmetrically fixedly installed at the top end of the shell 100, a pair of conductive plates 300 are respectively fixedly installed in the pair of circuit boards 400, the bottom end of the conductive plate 300 is connected with the transformer 700 through the power line provided, and the sealing knife 200 is electrically connected with the pair of conductive plates 300. The conductive plate 300 can be made of aluminum material.
[0044] By integrating the transformer 700 in the inner cavity of the shell 100 and arranging the sealing knife 200 at the top end of the shell 100, the line connection distance between the sealing knife 200 and the transformer 700 is shortened, so that the power line connection distance between the sealing knife 200 and the transformer 700 can be reduced, the power consumption is reduced, the power consumption is also reduced, and the overall size of the sealing knife 200 is also reduced.
[0045] Referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 3As shown, the current sensor 800 is arranged in the inner cavity of the shell 100, and is arranged close to the transformer. A current meter 110 is arranged on the outer side of the shell 100. The current sensor 800 is connected with the current meter 110 in communication. The current meter 110 is used for displaying the current value detected by the current sensor 800. In this way, the user can intuitively know the working current in the transformer coil at this time, and it is convenient for the user to master the working parameters of the heat sealing knife 200 at this time.
[0046] Continuing to refer to the drawings Figure 1 and the drawings Figure 3 As shown, in order to be able to adjust the working current entering the transformer, an adjusting knob 500 and a potentiometer 900 are further included. The potentiometer 900 is arranged in the inner cavity of the shell 100. The adjusting knob 500 is arranged on the outer side of the shell 100. The adjusting knob 500 is connected with the potentiometer 900. The potentiometer 900 is connected with the current input end of the transformer. The potentiometer 900 is used for adjusting the current value entering the transformer. For example, according to the different processing objects, the heat generated by the heat sealing knife 200 during use can be adjusted by changing the working current entering the transformer.
[0047] In some embodiments, the electric control part in the shell 100 needs to be subjected to potting treatment. For example, a potting protective layer is formed in the inner cavity of the shell 100. The transformer 700, the current sensor 800 and the potentiometer 900 are located inside the potting protective layer.
[0048] In some embodiments, an independent air duct extending to the heat sealing knife 200 is arranged in the shell 100. A heat dissipation fan is arranged in the independent air duct. In addition to dissipating heat for the components, the heat dissipation fan can also dissipate heat for the electrodes of the heat sealing knife 200. If the heat dissipation is not effective, high-temperature aging will occur.
[0049] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and equivalent technologies thereof, the present application also intends to include these modifications and variations.
