[0041] In this embodiment: In order to avoid the loss of accessories, most of the accessories are packaged in the packaging box and the packaging box is sealed. When sealing the packaging box, usually a paper packaging box is used, and a hand-held tape dispenser is used to seal the packaging box. Specifically, the head end of the tape is first attached to one side of the packaging box, then the tape dispenser is pulled to stretch the tape, and then the stretched tape is pressed on the position of the packaging box that needs to be sealed, and then the cutting piece on the tape dispenser is used to cut the tape. Although this method can seal the packaging box, using the tape dispenser is likely to cause hand fatigue and reduce the efficiency. In view of this, in order to solve this technical problem, a fixing component 2 and a packaging component 3 are added in this application document.

[0042] Combined with the above content, in order to facilitate the fixation of the packaging box when sealing the packaging box and prevent the packaging box from tilting during the sealing process, a fixing component 2 is further included, which is installed on the surface of the base 1. The fixing component 2 includes a bottom plate 21, a servo motor 22, a bidirectional lead screw 23, a screw block 24 and a abutting plate 25. The bottom plate 21 is installed on the surface of the base 1. The bidirectional lead screw 23 is rotatably connected in a groove opened on the surface of the bottom plate 21. One end of the bidirectional lead screw 23 penetrates the bottom plate 21 and extends to one side of the bottom plate 21 and is connected to the output shaft of the servo motor 22 installed on the surface of the base 1. Two screw blocks 24 are rotatably connected to the surface of the bidirectional lead screw 23, and abutting plates 25 are installed on the surfaces of the two screw blocks 24.

[0043] In this embodiment: When sealing the packaging box, first place the packaging box on the surface of the bottom plate 21, and start the servo motor 22 by control, so as to drive the bidirectional lead screw 23 connected to the rotating shaft of the servo motor 22 to rotate in the groove opened on the surface of the bottom plate 21. At this time, the two screw blocks 24 threadedly connected to the surface of the bidirectional lead screw 23 and located in the groove can move towards the side close to the packaging box at the same time, and the packaging box can be automatically aligned under the thrust of the two abutting plates 25 and clamped between the two abutting plates 25, which is convenient for fixing the packaging box when sealing the packaging box and preventing the packaging box from tilting during the sealing process.

[0044] It should be noted that: a rubber pad is provided on the surface of the abutting plate 25 close to the packaging box, which is used to increase the friction between the packaging box and the two abutting plates 25 and improve the clamping stability.

At this time, the threaded plate 201 threadedly connected to the surface of the screw 28 can drive the covering plate 202 to move on the surface of the screw 28, so that the covering plate 202 presses the two tongues integrally formed on the surface of the packaging box, so as to cover the two tongues integrally formed on the surface of the packaging box at the opening of the packaging box, limit the folded tongues, ensure stable folding, and at the same time can further fix the top of the packaging box.

[0047] In an alternative embodiment: a guide rod 29 is slidably connected in the through hole formed on the surface of the threaded plate 201, and one end of the guide rod 29 passing through the threaded plate 201 is connected to the screw block 24.

[0048] In this embodiment: based on this setting, when the threaded plate 201 threadedly connected to the surface of the screw 28 drives the covering plate 202 to move on the surface of the screw 28, the threaded plate 201 can move stably under the limit and guidance of the guide rod 29, avoiding deflection of the threaded plate 201 during the movement process.

[0049] In an alternative embodiment: a slide rod 204 is installed in the blind groove formed on the surface of the bottom plate 21, a slider 206 is slidably connected to the surface of the slide rod 204, a telescopic rod 207 is installed on the surface of the slider 206, and a pneumatic suction cup 209 is installed at the end of the telescopic rod 207 away from the slider 206.

[0050] In this embodiment: based on this setting, when the packaging box is placed on the surface of the bottom plate 21, the packaging box can be pushed to one side, and the packaging box can move on the surface of the bottom plate 21, so that one side of the packaging box contacts the provided pneumatic suction cup 209, which is beneficial to improving the stability of the packaging box during the sealing process.

[0051] In an optional embodiment: a spring 205 is sleeved on the outer surface of the slide rod 204, one end of the spring 205 abuts against a blind groove opened on the surface of the bottom plate 21, one end of the spring 205 abuts against the slider 206, a spring 208 is sleeved on the outer side of the telescopic rod 207, one end of the spring 208 abuts against the pneumatic suction cup 209, and the other end of the spring 208 abuts against the surface of the slider 206, and a stop bar 203 is installed on the surface of the bottom plate 21 and on the same side of the two abutting plates 25.

[0052] In the present embodiment: Based on this arrangement, when the packaging box is placed on the surface of the bottom plate 21 and pushed to one side, and when the packaging box moves on the surface of the bottom plate 21, the packaging box can push the pneumatic suction cup 209 to one side, and the slider 206 can slide to one side in the blind groove opened on the surface of the bottom plate 21, and the spring 1 205 can be in a compressed state, and one side of the packaging box can be elastically contacted with the stop bar 203, so as to elastically clamp the packaging box between the pneumatic suction cup 209 and the stop bar 203 (please refer to the above embodiment for details when fixing the packaging box in cooperation with the two abutment plates 25 and the two cover plates 202), and the arranged spring 208 can support the pneumatic suction cup 209 installed at one end of the telescopic rod 207.

[0053] It should be noted that the telescopic rod 207 is composed of two rods with different diameters, and the rod with a smaller diameter is slidably connected inside the rod with a larger diameter.

[0054] It should be noted that the pneumatic suction cup 209 is connected to a vacuum device (such as a vacuum generator) through a pipe, and then the object is in contact with the vacuum device, and suction is started to generate negative air pressure in the suction cup, thereby firmly sucking the object.

[0055] In an optional embodiment: in order to facilitate the sealing of the packaging box, a packaging assembly 3 is also included which is installed on the surface of the base 1. The packaging assembly 3 includes a hood 31, an electric telescopic rod 32, a hinge block 38, a hinge rod 39, a hinge seat 301, a slide plate 302, a tape roll 303 and a pressing plate 309. The hood 31 is installed on the surface of the base 1 and located outside the fixing assembly 2. The surface of the hood 31 is installed with an electric telescopic rod 32. The piston end of the electric telescopic rod 32 penetrates the hood 31. , and extends into the hood 31, and is connected to a pressure plate 309 arranged in the hood 31, a hinge block 38 is installed on one side surface of the pressure plate 309, a hinge rod 39 is hinged in the hinge block 38, and a hinge seat 301 is hinged at one end of the hinge rod 39 away from the hinge block 38, a slide plate 302 is slidably connected in a strip groove opened on the top surface of the inside of the hood 31, and a tape roll 303 is rotatably connected to the bottom surface of the slide plate 302 through a rotating shaft, and the hinge seat 301 is installed on one side of the bottom of the slide plate 302.

[0056] In this implementation: When encapsulating the packaging box clamped by the fixing component 2, it is necessary to pull one end of the tape wound around the surface of the tape roll 303 by a certain length, and make the back surface (non-adhesive surface) of one end of the tape contact with the pneumatic suction cup 209 provided. The pneumatic suction cup 209 adsorbs one end of the tape. When the packaging box is placed on the surface of the bottom plate 21 and one side of the packaging box elastically contacts the stop bar 203, it is convenient to elastically clamp the packaging box between the pneumatic suction cup 209 and the stop bar 203 (for the specific fixation of the packaging box in cooperation with the two abutting plates 25 and the two covering plates 202, refer to the above-mentioned embodiment). At this time, one end of the tape can be adhered to one side of the packaging box. Then, the piston end of the electric telescopic rod 32 can be controlled to extend, pushing the pressing plate 309 to move towards the side close to the packaging box inside the hood 31. At this time, the hinge block 38 installed on one side surface of the pressing plate 309 can push one end of the hinge rod 39 to slide down, and the other end of the hinge rod 39 can push the sliding plate 302 to slide towards one side in the strip-shaped groove opened on the inner top surface of the hood 31 through the hinge seat 301. At this time, it can drive the tape roll 303 installed on the bottom surface of the sliding plate 302 to slide towards one side, stretch the tape, and cover the surface of the tongue of the folded packaging box to seal the packaging box.

[0057] In an alternative embodiment: A guiding slide rod 307 is penetrated through the through hole opened on the surface of the sliding plate 302. The guiding slide rod 307 is installed in the strip-shaped groove opened on the inner top surface of the hood 31, and a fifth spring 308 is sleeved on the outer surface of the guiding slide rod 307. One end of the fifth spring 308 abuts against the strip-shaped groove opened on the inner top surface of the hood 31, and the other end of the fifth spring 308 abuts against the sliding plate 302.

[0058] In this embodiment: Based on this setting, when the other end of the hinge rod 39 pushes the sliding plate 302 to slide towards one side in the strip-shaped groove opened on the inner top surface of the hood 31 through the hinge seat 301, the sliding plate 302 can slide on the surface of the guiding slide rod 307 installed in the strip-shaped groove, and can push and compress the fifth spring 308. At the same time, it is convenient to reset under the elastic action of the fifth spring 308 provided.

[0059] In an alternative embodiment: A fixing plate 304 is installed on one side of the bottom of the sliding plate 302. A T-shaped guiding rod 311 is slidably connected in the through hole opened on the surface of the fixing plate 304. One end of the T-shaped guiding rod 311 penetrates through the fixing plate 304 and extends to the bottom of the fixing plate 304 and is connected to the abutting roller 306 provided at the bottom of the fixing plate 304. A fourth spring 305 is sleeved on the outer surface of the T-shaped guiding rod 311. One end of the fourth spring 305 abuts against the abutting roller 306, and the other end of the fourth spring 305 abuts against the fixing plate 304. Grooves are opened on the surface of the T-shaped guiding rod 311 along its length direction, and the through hole opened on the surface of the fixing plate 304 matches the T-shaped guiding rod 311.

[0060] Based on this setting, when the other end of the hinge rod 39 pushes the sliding plate 302 to slide to one side in the strip-shaped groove opened on the inner top surface of the hood 31 through the hinge seat 301, it can drive the fixed plate 304 to slide to one side. At the same time, the abutting roller 306 elastically connected by the fourth spring 305 can compact the tape covering the surface of the tongue of the folded packaging box, which is beneficial to improving the sealing quality and ensuring that the tape adheres to the surface of the tongue of the packaging box. At the same time, the cooperation between the groove on the surface of the T-shaped guide rod 311 and the through groove opened on the surface of the fixed plate 304 that matches the T-shaped guide rod 311 can facilitate the position limitation of the abutting roller 306 and prevent the abutting roller 306 from deflecting.

[0061] It should be noted that: the abutting roller 306 is limited by the T-shaped guide rod 311 to ensure that the lowest position of the abutting roller 306 is slightly lower than the surface of the packaging box. At the same time, through the arc-shaped roller frame, it is convenient for the abutting roller 306 to be slightly adjusted upward under the action of force from one side of the packaging box during the process of moving to one side, and the elastically arranged abutting roller 306 flattens the surface of the tape.

[0062] In an alternative embodiment: Two T-shaped connecting rods 33 are symmetrically arranged on the bottom surface of the pressing plate 309, and a blind groove with a T-shaped structure that matches the T-shaped connecting rods 33 is opened on the bottom surface of the pressing plate 309. The T-shaped connecting rods 33 are slidably connected to the bottom surface of the pressing plate 309 through this blind groove, and abutting side rollers 36 are installed at the same end of the two T-shaped connecting rods 33.

[0063] In this embodiment: Based on this setting, it is convenient for the tape roll 303 on the bottom surface of the sliding plate 302 to slide to one side, stretch the tape, and cover the surface of the tongue of the folded packaging box. Under the action of the electric telescopic rod 32, it can continue to push the tape roll 303 to slide to one side. At the same time, the two T-shaped connecting rods 33 installed on the pressing plate 309 can drive the abutting side rollers 36 installed at one end of them to move downward, press the tape on one side surface of the packaging box, and flatten the tape on both sides to ensure the adhesion between the tape and the packaging box.

[0064] In an alternative embodiment: A fixing rod 34 is penetrated through the through hole opened at one end of the T-shaped connecting rod 33. The fixing rod 34 is installed in the blind groove opened on the bottom surface of the pressing plate 309, and a third spring 35 is sleeved on the outer surface of the fixing rod 34. One end of the third spring 35 abuts against the blind groove opened on the bottom surface of the pressing plate 309, and the other end of the third spring 35 abuts against the T-shaped connecting rod 33. A cutter 37 is installed on one side of one of the abutting side rollers 36.

[0065] In this embodiment: Based on this setting, when the pressing side roller 36 moves downward to contact the surface of the packaging box, the packaging box can apply pressure to both sides of the two pressing side rollers 36, and the two pressing side rollers 36 can ensure an elastic abutting state with the packaging box under the self-elasticity of the third spring 35, so as to bond the tape on both sides of the packaging box to the packaging box more firmly. At the same time, when the pressing side roller 36 presses down, the inclination angle of the tape can be changed. When the moving angle is reached, the cutter 37 provided on one side of the pressing side roller 36 can cut the tape, thereby achieving the purpose of sealing the packaging box.

[0066] It should be noted that: The distance between the two pressing side rollers 36 is slightly smaller than the size of the packaging box. At the same time, through the roller frame arranged in an arc shape, it is convenient for the two pressing side rollers 36 to move slightly to both sides under the action of the downward pressure and the horizontal force of the packaging box during the process of moving to one side, and the elastically arranged pressing side rollers 36 can flatten the tape on the side of the packaging box.

[0067] Finally, it should be noted that: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
