[0032] Embodiment 1

[0033] Referring to Figure 1 , which is the first embodiment of the present utility model. This embodiment provides a packing device,

[0034] including an encapsulation assembly 100, which includes a platform 101, a conveying rack 102 and a blanking rack 103 used in conjunction with the platform 101, fixing racks 104 symmetrically installed on the platform 101, and a sealing member 105 used in conjunction with the fixing racks 104. The carton is sealed by the sealing member 105;

[0035] an adjustment assembly 200, which includes a servo motor 201 and a lead screw 202 arranged on the fixing rack 104. The servo motor 201 is fixedly installed at the top of the fixing rack 104. The lead screw 202 is rotatably installed on the fixing rack 104, sliding grooves 203 symmetrically opened on the platform 101, sliders 204 slidably installed in the sliding grooves 203, a rotating member 205 arranged at the bottom of the platform 101. The distance between two clamping plates 105d can be adjusted through the rotating member 205 to adapt to cartons of different sizes, and a guiding member 206 used in conjunction with the rotating member 205 to guide the carton;

[0036] The rotating assembly 300 includes a connecting frame 301 hinged to the blanking rack 103. Baffles are provided on both sides of the top end of the connecting frame 301, a cross plate 302 and a second spring 303 provided on the blanking rack 103. The cross plate 302 is slidably installed on the blanking rack 103 and can be reset by the second spring 303. When each carton is being packed, there will be a gap between it and the previously dropped carton. At the same time, when the second spring 303 resets the connecting frame 301 and the cross plate 302, due to the reaction force, the second spring 303 will drive the connecting frame 301 and the cross plate 302 to shake up and down. And the interval time can just make the second spring 303 smooth, so that the second spring 303 will not move up and down repeatedly. A traction member 304 used in conjunction with the connecting frame 301 can slow down the rotation speed of the connecting frame 301 to prevent the connecting frame 301 from colliding with and damaging the cross plate 302, and a limiting rod 305 inserted between the blanking rack 103 and the connecting frame 301 to fix the connecting frame 301 through the limiting rod 305.

[0037] Specifically, the sealing member 105 includes a lifting frame 105a provided between two fixed frames 104 and a carton sealing member 105b provided on the lifting frame 105a. The carton sealing member 105b is a carton sealer, which has the following functions: Carton positioning and conveying: The carton sealer conveys the carton to be sealed to the designated position through a conveyor belt. During this process, the machine will use devices such as photoelectric sensors to ensure the accurate positioning of the carton; Tape pasting and sealing: After the opening adjustment is completed, the carton sealer will automatically paste the pre-cut tape at the opening of the carton. The carton sealer will precisely control the length and pasting position of the tape to ensure the firmness and aesthetics of the seal; Sealing compaction and detection: After the tape is pasted, the carton sealer will perform a compaction operation on the seal to ensure that the tape is tightly combined with the carton. At the same time, the machine will also detect the sealing quality through a self-inspection system to ensure that the seal of each carton meets the standards. An extension plate 105c fixedly installed on the carton sealing member 105b, and clamping plates 105d and a conveyor belt 105e symmetrically provided on the platform 101. A power source is provided on one side of the conveyor belt 105e to convey the carton.

[0038] Furthermore, one end of the extension plate 105c away from the carton sealing member 105b is set as an inclined surface, and both ends of the opposite surfaces of the two clamping plates 105d are set as inclined surfaces.

[0039] Operation process: When in use, the cardboard box on the conveying rack 102 is pushed onto the platform 101, and the conveyor belt 105e starts to convey the cardboard box through the power source. While conveying, the cardboard box is guided by the inclined surfaces of the two clamping plates 105d, so that the cardboard box can be accurately positioned between the two clamping plates 105d, and the two sides of the cardboard box are clamped by the two clamping plates 105d. When the cardboard box moves below the extension plate 105c, since the opening of the cardboard box may be tilted, as the cardboard box is conveyed by the conveyor belt 105e, at this time, the tilted opening is squeezed by the inclined surface of the extension plate 105c, so that the opening of the cardboard box is flattened, thus ensuring subsequent packaging. As the cardboard box is conveyed, when it moves below the sealing member 105b, the sealing member 105b pastes and tapes the seal of the cardboard box for packaging, and cuts the tape, and then conveys the packaged cardboard box to the blanking rack 103 for the staff to unload.

[0040] Embodiment 2

[0041] Refer to Figure 2 - Figure 4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the rotating member 205 includes a support plate 205a symmetrically installed on the platform 101, a positive and negative thread screw rod 205b rotatably installed on the support plate 205a, a belt 205c arranged between the two positive and negative thread screw rods 205b, and connection blocks 205d symmetrically and threadedly installed on the positive and negative thread screw rods 205b.

[0042] Specifically, one end of the screw rod 202 is fixedly connected to the output end of the servo motor 201. The screw rod 202 is driven by the servo motor 201 to rotate. The lifting frame 105a is threadedly installed on the screw rod 202, and the lifting frame 105a can be lifted and lowered by the rotation of the screw rod 202. The slider 204 is fixedly installed on the clamping plate 105d.

[0043] Furthermore, one end of one of the positive and negative thread screw rods 205b extends to the outside of the support plate 205a, and a turntable is fixedly connected to this end. A fixed connection is made between the top of the connection block 205d and the slider 204.

[0044] Furthermore, the guiding member 206 includes rotating plates 206a and fixing plates 206b symmetrically arranged on the conveying rack 102, and a first spring 206c arranged between the rotating plates 206a and the fixing plates 206b.

[0045] The rest of the structures are the same as those in Embodiment 1.

[0046] Operation process: When it is necessary to adjust the height of the carton sealing member 105b, start the servo motor 201. Drive the lead screw 202 to rotate through the servo motor 201. Make the lifting frame 105a drive the carton sealing member 105b to lift and lower through the forward and reverse rotation of the lead screw 202. When it is necessary to adjust the distance between the two clamping plates 105d, rotate the turntable to make the double-threaded lead screw 205b connected thereto rotate. While rotating, make the other double-threaded lead screw 205b rotate synchronously through the transmission of the belt 205c. Through the forward and reverse rotation of the double-threaded lead screw 205b, make the connecting blocks 205d on both sides move forward and backward, drive the slider 204 while moving, and make the two clamping plates 105d also move accordingly, so as to adjust the distance between the two clamping plates 105d, so that the device can be applicable to cartons of different sizes, thereby improving the application scenarios. At the same time, when the two clamping plates 105d move, the rotating plate 206a will also rotate through the reaction force of the first spring 206c, so that one end of the rotating plate 206a is always in contact with the clamping plate 105d. As the clamping plate 105d moves, the distance between the two rotating plates 206a will also change, so as to accurately guide the carton between the two clamping plates 105d.

[0047] Embodiment 3

[0048] Refer to Figure 5 - Figure 7 This is the third embodiment of the present invention. The difference between this embodiment and the above embodiments is that the traction member 304 is symmetrically installed on the winding wheel 304a on the blanking frame 103, the rope 304b wound around the winding wheel 304a, and the counterweight 304c fixedly installed on the rope 304b.

[0049] Specifically, the other end of the rope 304b is fixedly connected to the connecting frame 301, and a plurality of conveying rollers are provided on both the connecting frame 301 and the conveying frame 102.

[0050] Furthermore, clamping grooves 306 are opened on both sides of the connecting frame 301, a placement groove is opened on one side of the blanking frame 103 close to the clamping groove, a circular groove 307 is opened on one side of the placement groove far from the clamping groove, one end of the limiting rod 305 is engaged with the clamping groove 306, and the other end is located between the circular grooves 307.

[0051] The remaining structures are the same as those in Embodiment 2.

[0052] Operation process: When it is necessary to convey the packaged carton to the ground, by pulling the limiting rods 305 on both sides outwards, the limiting rods 305 are no longer engaged with the card slots 306 and are located between the placement slots. Thus, there is no need to pull out the limiting rods 305 to prevent loss. At this time, the connecting frame 301 will rotate through the hinge, causing one end of the connecting frame 301 to deflect downwards. While deflecting, the rope 304b is pulled, causing one end of the rope 304b to descend along with the connecting frame 301, and the other end to lift the counterweight 304c upwards. Due to the weight of the counterweight 304c, the deflection rate of the connecting frame 301 can be slowed down to prevent the connecting frame 301 from colliding when it contacts the cross plate 302. At this time, when the carton moves onto the connecting frame 301, it will move downwards due to the inclined connecting frame 301. At the same time, the baffles on both sides of the connecting frame 301 can prevent the carton from slipping. While moving, the weight of the connecting frame 301 will also increase, causing the connecting frame 301 to press on the cross plate 302 and make it descend, thereby reducing the height between the connecting frame 301 and the ground to prevent the carton from being damaged due to collision when it falls to the ground. When each carton is packed, there will be a gap between it and the previously fallen carton. At the same time, when the second spring 303 resets the connecting frame 301 and the cross plate 302, the reaction force will cause the second spring 303 to drive the connecting frame 301 and the cross plate 302 to shake up and down. And the interval time can just smooth the second spring 303, so that the second spring 303 will not move up and down repeatedly. After use, lift the connecting frame 301 to reset it, and then reinsert the limiting rods 305 to engage with the card slots 306 to fix the connecting frame 301. At the same time, the weight of the counterweight 304c will also pull the rope 304b to reset, and the cross plate 302 can be reset by the reaction force of the second spring 303.
