Specific implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0029] Embodiment 1:

[0030] A continuous drying device for processing and producing packaging boxes includes a conveyor 1 and a drying box 2. The drying box 2 is fixedly installed on the outer surface of the conveyor 1. A controller 3 is fixedly installed on one side of the drying box 2. A roller 4 is drivingly connected inside the conveyor 1. Support blocks 5 are arranged inside the drying box 2. Two lifting blocks 6 are arranged on the top of the support block 5. A plurality of lifting rods 7 are fixedly connected to the top of the lifting block 6. A lifting mechanism is fixedly connected to the bottom of the support block 5. An adjusting mechanism is arranged at the bottom of the lifting block 6;

[0031] The lifting mechanism includes a support frame 8 installed at the bottom of the drying box 2. A motor 9 is fixedly installed at the bottom of the support frame 8. The motor 9 is electrically connected to the controller 3. The output end of the motor 9 penetrates into the inside of the support frame 8 and is fixedly connected to a lead screw 10. A transmission block 11 is drivingly connected to the surface of the lead screw 10. The top of the transmission block 11 is fixedly connected to a transmission rod 12. The top of the transmission rod 12 penetrates into the inside of the drying box 2 and is fixedly connected to the bottom of the support block 5;

[0032] An infrared sensor 13 is fixedly installed inside the drying box 2. A touch sensor 14 is fixedly installed on the inner wall of the support frame 8. Both the infrared sensor 13 and the touch sensor 14 are signal-connected to the controller 3.

[0033] In this embodiment, considering that when the packing box is conveyed on the continuous drying device, it is difficult to obtain sufficient drying for the bottom of the packing box because it contacts the roller 4 of the conveyor 1, which affects the drying effect of the packing box. Therefore, by setting up a lifting mechanism, the packing box can be placed on the conveyor 1, and then the conveyor 1 is started by the controller 3 to convey the packing box, so that the packing box enters the drying box 2 for drying. When the infrared sensor 13 inside the drying box 2 receives that the packing box has moved to the designated position, it transmits a signal to the controller 3. At this time, the PLC module built into the controller 3 will stop the conveyor 1 and start the motor 9 to rotate at the same time. The motor 9 will drive the lead screw 10 to rotate around the bearing block 28. When the lead screw 10 rotates, it will drive the transmission block 11, so that the transmission block 11 moves up and down reciprocally along the trajectories of the sliding block 26 and the sliding groove 27. When the transmission block 11 moves upward, it will drive the transmission rod 12, the support block 5 and the lifting block 6 to move upward, and at the same time drive the lifting rod 7 and the lifting block 24 to lift the packing box, so that the hot air in the drying box 2 can effectively contact the bottom of the packing box and improve the drying effect;

[0034] It solves the problem that when considering the conveyance of the packing box on the continuous drying device, it is difficult to obtain sufficient drying for the bottom of the packing box because it contacts the roller 4 of the conveyor 1, which affects the drying effect of the packing box;

[0035] It should be noted that when the transmission block 11 moves downward and touches the touch sensor 14, the touch sensor 14 will transmit a signal to the controller 3. The PLC module built into the controller 3 will turn off the motor 9 and start the conveyor 1 at the same time to convey the packing box out of the inside of the drying box 2.

[0036] A lifting block 24 is arranged at the top of the lifting rod 7, and a rubber block 25 is fixedly connected to the top of the lifting block 24.

[0037] In this embodiment, by setting the lifting block 24 and the rubber block 25, the stability of lifting the packing box can be improved. At the same time, the rubber block 25 can avoid hard contact with the packing box and cause damage to the packing box. The material of the rubber block 25 is heat-resistant rubber and will not melt and deform in the drying box 2.

[0038] Sliding blocks 26 are fixedly connected to both sides of the transmission block 11, and sliding grooves 27 matching with the sliding blocks 26 are formed in the inner wall of the support frame 8.

[0039] In this embodiment, by setting the sliding blocks 26 and the sliding grooves 27, when the lead screw 10 rotates to drive the transmission block 11, the transmission block 11 can be restricted to move up and down reciprocally only along the trajectories of the sliding blocks 26 and the sliding grooves 27.

[0040] A bearing block 28 is arranged at the top of the lead screw 10, and it is rotationally connected to the bottom of the drying box 2 through the bearing block 28.

[0041] In this embodiment, by providing the bearing block 28, the lead screw 10 can be supported, and at the same time, the lead screw 10 is restricted to rotate only around the bearing block 28, while improving the smoothness during the rotation process.

[0042] Embodiment Two:

[0043] Based on Embodiment One, in this embodiment, the lifting mechanism can lift the packaging box by controlling the lifting rod 7 to rise, so as to effectively dry the bottom of the packaging box and improve the drying efficiency. However, considering that the widths of the packaging boxes are different, if the distance between the two groups of lifting rods 7 does not match, the packaging box cannot be lifted, thus affecting the drying of the bottom of the packaging box. In this application, the adjusting mechanism includes two shells 15 fixedly connected to the bottom of the support block 5. A moving block 16 is arranged inside the shell 15. One side of the moving block 16 is fixedly connected to a positioning rod 17. One end of the positioning rod 17 penetrates to the outside of the shell 15. A plurality of positioning holes 18 are formed on both sides of the support block 5. One side of the moving block 16 away from the positioning rod 17 is fixedly connected to a traction rod 19. One end of the traction rod 19 penetrates to the outside of the shell 15 and is fixedly connected to a traction block 20.

[0044] In this embodiment, considering that the widths of the packaging boxes are different, if the distance between the two groups of lifting rods 7 does not match, the packaging box cannot be lifted, thus affecting the drying of the bottom of the packaging box. Therefore, by providing the adjusting mechanism, the doors on both sides of the drying box 2 can be opened, and then the two traction blocks 20 are pulled to drive the traction rod 19 and the moving block 16 to move. The moving block 16 will drive the positioning rod 17 to leave the inside of the positioning hole 18, releasing the restriction on the lifting block 6. Then, the positions of the lifting block 6 and the lifting rod 7 can be adjusted along the trajectories of the T-shaped block 22 and the T-shaped sliding groove 23. After reaching the appropriate position, the traction block 20 is released, and the elastic force generated by the spring 21 pushes the moving block 16 and the positioning rod 17 to move, so that the positioning rod 17 enters the corresponding positioning hole 18, completing the adjustment of the position of the lifting rod 7. The position of the lifting rod 7 can be adjusted according to the width of the packaging box, so as to effectively lift the packaging box and dry its bottom;

[0045] It solves the problem that considering the different widths of the packaging boxes, if the distance between the two groups of lifting rods 7 does not match, the packaging box cannot be lifted, thus affecting the drying of the bottom of the packaging box.

[0046] A spring 21 is sleeved on the surface of the traction rod 19. One end of the spring 21 is fixedly connected to the inner wall of the shell 15, and the other end of the spring 21 is fixedly connected to one side of the moving block 16.

[0047] In this embodiment, by providing the spring 21, after the traction block 20 is released, the elastic force generated by the spring 21 can push the moving block 16 and the positioning rod 17 to reset, so that the positioning rod 17 enters the corresponding positioning hole 18.

[0048] A T-shaped block 22 is fixedly connected to the bottom of the lifting block 6, and a T-shaped sliding groove 23 adapted to the T-shaped block 22 is provided at the top of the support block 5.

[0049] In this embodiment, by providing the T-shaped block 22 and the T-shaped sliding groove 23, the movement track of the lifting block 6 can be restricted, so that it can only be horizontally adjusted along the tracks of the T-shaped block 22 and the T-shaped sliding groove 23.

[0050] Working principle: Place the packing box on the conveyor 1, and then start the conveyor 1 through the controller 3 to convey the packing box, so that the packing box enters the drying box 2 for drying. When the infrared sensor 13 inside the drying box 2 receives that the packing box has moved to the designated position, it transmits a signal to the controller 3. At this time, the built-in PLC module of the controller 3 will stop the conveyor 1 and start the motor 9 to rotate at the same time. The motor 9 will drive the lead screw 10 to rotate around the bearing block 28. When the lead screw 10 rotates, it will drive the transmission block 11, so that the transmission block 11 makes a reciprocating up and down movement along the tracks of the sliding block 26 and the sliding groove 27. When the transmission block 11 moves upward, it will drive the transmission rod 12, the support block 5 and the lifting block 6 to move upward, and at the same time drive the lifting rod 7 and the lifting block 24 to lift the packing box, so that the hot air in the drying box 2 can effectively contact the bottom of the packing box, improving the drying effect;

[0051] At the same time, the box doors on both sides of the drying box 2 can be opened, and then the two traction blocks 20 are pulled to drive the traction rod 19 and the moving block 16 to move. The moving block 16 will drive the positioning rod 17 to leave the inside of the positioning hole 18, releasing the restriction on the lifting block 6. Then, the positions of the lifting block 6 and the lifting rod 7 can be adjusted along the tracks of the T-shaped block 22 and the T-shaped sliding groove 23. After reaching the appropriate position, release the traction block 20, and the elastic force generated by the spring 21 will push the moving block 16 and the positioning rod 17 to move, so that the positioning rod 17 enters the corresponding positioning hole 18, completing the adjustment of the position of the lifting rod 7, enabling the lifting rod 7 to adjust its position according to the width of the packing box, so as to effectively lift the packing box and dry its bottom.

[0052] It should be noted that the conveyor 1, the drying box 2, the controller 3, the motor 9, the infrared sensor 13 and the touch sensor 14 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art, and the specific composition and principle of the power supply of the conveyor 1, the drying box 2, the controller 3, the motor 9, the infrared sensor 13 and the touch sensor 14 are clear to those skilled in the art, so they will not be elaborated in detail.

[0053] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
