In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

In one embodiment, as shown in fig. 1 and 2, a package heat-seal apparatus includes: a mounting base 100, a first mounting bracket 200, a second mounting bracket 300, a first heat seal 400, a second heat seal 500 and an elastic component 600, wherein the first mounting bracket 200 and the second mounting bracket 300 are rotatably mounted on the mounting base 100, the first mounting bracket 200 and the second mounting bracket 300 form a mounting cavity for placing a packing material, the first heat seal 400 is mounted on one side of the first mounting bracket 200 facing the second mounting bracket 300, the second heat seal 500 is mounted on the second mounting bracket 300, the first heat seal 400 and the second heat seal 500 are respectively used for contacting two opposite sides of the packing material, a first elastic pad 201 is arranged between the first heat seal 400 and the first mounting bracket 200, and/or a second elastic pad (not labeled) is arranged between the second heat seal 500 and the second mounting bracket 300, the elastic member 600 is used for elastic compensation of the first heat seal 400 and the second heat seal 500 in the direction toward the packing material.

When the first heat seal 400 and the second heat seal 500 are heat sealed, the first heat seal 400 moves relative to the package material on the first mounting bracket 200, and/or the second heat seal 500 moves relative to the package material on the second mounting bracket 300, and the elastic component 600 is used for compensating the elasticity of the first heat seal 400 and the second heat seal 500 in the direction toward the package material.

When the packaging heat-sealing device is used, the first mounting bracket 200 and the second mounting bracket 300 are rotatably mounted on the mounting base 100, that is, the first mounting bracket 200 and the second mounting bracket 300 rotate relatively on the mounting base 100 to realize the joint and collision of the packaging materials to be processed. Install first heat-seal 400 additional on first installing support 200 and install second heat-seal 500 additional on second installing support 300, realized heat-seal conflict when to wrapping material both sides. Further, in order to ensure that the first heat seal member 400 and the second heat seal member 500 can both be in sufficient contact with the packaging material, the first mounting bracket 200 and the second mounting bracket 300 can be further moved towards the direction close to the packaging material, that is, the interference force of the first heat seal member 400 and the second heat seal member 500 on the packaging material is increased. After the first heat sealing member 400 and the second heat sealing member 500 are both abutted against the packaging material, the first elastic pad 201 is elastically compressed between the first heat sealing member 400 and the first mounting bracket 200 by the abutting force applied by the first mounting bracket 200 and the second mounting bracket 300 toward the packaging material, i.e., the first heat sealing member 400 is moved to be attached to the first mounting bracket 200, and/or the second elastic pad is elastically compressed between the second heat sealing member 500 and the second mounting bracket 300, i.e., the second heat sealing member 500 is moved to be attached to the second mounting bracket 300 relative to the packaging material.

In this embodiment, according to the requirement of processing and installation of the packing material, the fourth heat sealing plate 520 may be installed on only the third bar 310 or the fourth bar 320, or the fourth sealing plate may be installed on both the third bar 310 and the fourth bar 320.

Specifically, after the third heat dissipation plate is attached to the packing material, the fourth heat sealing plate 520 can move toward the fourth connecting rod under the action of the forces applied by the first mounting bracket 200 and the second mounting bracket 300, and the fourth heat sealing plate 520 can be ensured to be attached to and abutted against the packing material all the time under the action of the elastic force of the first spring member 610.

When the packaging heat sealing device is performing heat sealing on a packaging material, the cutter 240 is accommodated in the first cutting groove 411, so that the situation that the cutter 240 accidentally cuts the packaging material which is not subjected to heat sealing by the cutter is avoided. After the packaging material is subjected to heat sealing in the packaging and heat sealing device, the packaging material can form a first package and a second package which are connected in the packaging and heat sealing device, at the moment, the cutting driving piece 250 drives the cutter piece 240 to move through the transmission piece 260, namely, the cutter piece 240 can cut off the joint of the first package and the second package in the moving process, and therefore the first package and the second package are separated. Further, in the cutting process of the cutter, a second cutting groove for the cutter to extend into is formed in the third heat sealing plate 510, so that the cutter can be in a sufficient range in the packaging and heat sealing device, that is, the first package and the second package which are cut by the cutter can be completely separated.

As shown in fig. 1 and 2, in one embodiment, the package heat sealing device further includes a first driving member 700 and a second driving member 800, the first driving member 700 is connected to the first mounting bracket 200, the first driving member 700 is used for driving the first mounting bracket 200 to rotate relative to the packing material, the second driving member 800 is connected to the second mounting bracket 300, and the second driving member 800 is used for driving the second mounting bracket 300 to rotate relative to the packing material.

Specifically, when the package heat sealing device performs heat sealing, the first mounting bracket 200 and the second mounting bracket 300 move toward the center line (which refers to the center line between the first mounting bracket 200 and the second mounting bracket 300) and are folded, and sometimes the package material may be in the folding range of the first mounting bracket 200 and the second mounting bracket 300 (which refers to the folding range of the package heat sealing device except the heat sealing range formed by the first heat seal 400 and the second heat seal 500), and at this time, the package material may be damaged by continuing the folding operation of the first mounting bracket 200 and the second mounting bracket 300. Therefore, in the present embodiment, the first heat-seal protection cover 270 protrudes from the first connecting rod 230 and the second heat-seal protection cover 340 protrudes from the second connecting rod 330. I.e., to ensure that the first heat seal protector 270 and the second heat seal protector 340 can contact the package material before the first heat seal 400 and the second heat seal 500. Meanwhile, the first position sensor 350 senses the position change of the first heat-seal protection cover 270 and the second heat-seal protection cover 340, and the second position sensor 360 senses the position change of the second driving member 800. If the first position sensor 350 senses a position change signal and the second position sensor 360 does not sense a position change signal, it indicates that the packaging heat sealing device has accidentally clamped the packaging material, and at this time, the first mounting bracket 200 and the second mounting bracket 300 need to be opened and closed.

In one embodiment, a first heater bar is disposed within the first heat seal 400 and a second heater bar is disposed within the second heat seal 500. Specifically, the above embodiment can effectively reduce the heat loss of the first heat seal 400 and the second heat seal 500, and improve the heat sealing efficiency of the packing material.
