[0002] Most cosmetics are packaged in boxes. In order to protect the outer surface of the box, a layer of plastic film is usually wrapped on the outside of the box and then sealed by heat sealing. Since the heat sealing edges of the plastic film are on the left and right sides of the box, the left and right sides of the box need to be sealed.

[0003] However, existing packaging box side heat sealing devices still have some shortcomings during use. For example, it is difficult to adjust the heat sealing position of the packaging box, which makes it inconvenient for workers to operate the heat sealing and cannot be adjusted according to actual needs, which reduces the heat sealing progress. In addition, it is difficult to limit and fix the packaging box when it is placed, which makes it easy to shift during the heat sealing process, thereby reducing the practicality of the heat sealing device. In view of the above shortcomings, it is necessary to design a semi-automatic packaging box side heat sealing device. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4As shown, the utility model provides a technical solution: a semi-automatic packaging box side heat sealing device, including a workbench 1, a lifting mechanism 2, an adjusting mechanism 3, a heat sealing mechanism 4, a protective mechanism 5 and a limiting mechanism 6. The lifting mechanism 2 is installed on the workbench 1, the adjusting mechanism 3 is installed on the lifting mechanism 2, the heat sealing mechanism 4 is installed at the bottom of the adjusting mechanism 3, the protective mechanism 5 is provided on the periphery of the heat sealing mechanism 4, and the limiting mechanism 6 is installed on the workbench 1, and the limiting mechanism 6 is located below the heat sealing mechanism 4.

[0025] The lifting mechanism 2 in this embodiment includes a lifting plate 201, which is fixedly connected to the piston rod of the cylinder 202. The cylinder 202 is installed on the top plate 203, and the top plate 203 is installed on the workbench 1 through multiple support rods 204. A sleeve 205 is slidably provided on the support rod 204, and the sleeve 205 is installed on the lifting plate 201.

[0026] The adjustment mechanism 3 in this embodiment includes a screw 301 and a handwheel 302. The handwheel 302 is installed at one end of the screw 301. The screw 301 is rotatably installed between two screw seats 303. The screw seat 303 is installed at the bottom of the connecting plate 304. The bottom of the connecting plate 304 is installed with a slide rail 305. The bottom of the slide rail 305 is slidably provided with a first slider 306. The top of the connecting plate 304 is installed on the lifting plate 201. The screw 301 is screwed with a screw nut 307, and the screw nut 307 is installed on the connecting block 308. The handwheel 302 drives the screw 301 to rotate, and the screw nut 307 is driven by the screw 301 to move. The connecting block 308 and the heat sealing head mounting plate 402 also move accordingly, thereby driving the heat sealing head 401 to move to adjust the position of the heat sealing head. This allows the heat sealing device to be adjusted according to the processing position of the packaging box, facilitating heat sealing at different positions of the packaging box.

[0027] The heat sealing mechanism 4 in this embodiment includes a heat sealing head 401. The heat sealing head 401 serves as a heat transfer component. The high temperature conducted thereby melts the packaging material at the sealing point and presses it together, thereby achieving the heat sealing process. The heat sealing head 401 is internally provided with an S-shaped electric heating wire. The heat sealing head 401 is also internally provided with a temperature sensor, which is electrically connected to a temperature controller. The heat sealing head 401 is mounted on the bottom of a heat sealing head mounting plate 402. A protective cover 403 is provided on the heat sealing head mounting plate 402. The heat sealing head mounting plate 402 is mounted on the bottom of the first slider 306. The top of the heat sealing head mounting plate 402 is fixedly connected to the connecting block 308. The temperature sensor detects the temperature of the heat sealing head and feeds back the detection result to the temperature controller. When the temperature of the heat sealing head is too low, the temperature controller controls the electric heating wire to continue to be energized to heat it to a set temperature value. When the temperature reaches the set temperature value, the temperature controller controls the electric heating wire to stop energizing the heating.

[0028] The protective mechanism 5 in this embodiment includes a protective cover 501, which is a hollow rectangular structure. The top of the protective cover 501 is fixedly connected to one end of a plurality of guide rods 502. A guide sleeve 503 is sleeved on the guide rod 502, and the guide sleeve 503 is installed on the heat sealing head mounting plate 402. The other end of the guide rod 502 is fixedly connected to the limit block 504. A first spring 505 is sleeved on the guide rod 502, and one end of the first spring 505 abuts against the heat sealing head mounting plate 402, and the other end of the first spring 505 abuts against the protective cover 501.

[0029] The limiting mechanism 6 in this embodiment includes a limiting plate 601 slidably arranged on the workbench 1. The limiting plate 601 contacts the packaging box and is used to limit the position of the packaging box. Two rows of limiting holes 101 are provided on the workbench 1. Slide grooves 102 are provided at both ends of the workbench 1. Slide cylinders 602 are installed at both ends of the limiting plate 601. The slide cylinder 602 is a hollow cylinder. A sliding block 603 is slidably arranged inside the slide cylinder 602. The sliding block 603 is installed on the pull rod 604. The pull rod 604 is sleeved with a second spring 605. A second slider 606 is installed at the bottom of the limiting plate 601. The second slider 606 is slidably arranged in the slide groove 102. One end of the pull rod 604 extends out of the slide cylinder 602 and is fixedly connected to the pull ring 607. The other end of the pull rod 604 passes through the slide cylinder 602 and the limiting plate 601 and is inserted into the limiting hole 101. By pulling the pull ring 607, the pull rod 604 moves upward, so that the bottom of the pull rod 604 leaves the limiting hole 101 and retracts into the slide 602, pushing the limiting plate 601 to move along the slide groove 102 to adjust the position of the limiting plate 601, so that the limiting plate 601 can be adjusted according to the size of the packaging box, thereby facilitating the heat sealing of the packaging boxes of different sizes. After the adjustment is completed, the pull ring 607 is released, and under the action of the elastic force of the second spring 605 itself, the sliding block 603 and the pull rod 604 are pushed downward, so that the pull rod 604 is stuck in the limiting hole 101 of the workbench 1, thereby fixing the limiting plate 601 on the workbench 1.

[0030] The working principle of the present invention is as follows: when in use, the packaging box wrapped with the flexible packaging plastic film is placed on the workbench 1, and one end of the packaging box is pressed against the front end of the limit plate 601, the cylinder 202 pushes the lifting plate 201 to move downward, and the adjusting mechanism 3, the heat sealing mechanism 4 and the protective mechanism 5 also move downward, thereby driving the heat sealing head 401 to move downward, and the electric heating wire is energized to heat the heat sealing head 401, so that the heat sealing head 401 performs heat sealing work on the packaging box, and in this process, the protective cover 501 will first contact the packaging box to be heat sealed, and position it, and also prevent workers from The first spring 505 is pressed against the heat sealing head 401 to prevent the heat sealing head 401 from being burned, thereby reducing safety hazards and improving safety protection for the heat sealing head 401. When the protective cover 501 contacts the package to be heat-sealed, the cylinder 202 continues to drive the heat sealing head 401 to press down, so that the first spring 505 is squeezed and contracted. When the heat sealing head 401 completes the heat sealing work of the package to be heat-sealed, the cylinder 202 resets and drives the heat sealing head 401 to move upward. In this process, the first spring 505 pushes the protective cover 501 downward under the action of its own elastic force, so that the heat sealing head 401 leaves the heat-sealed package, thereby preventing the package from sticking to the heat sealing head 401.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
