[0030] This application relates to a packaging box fastener repressing machine, which includes an inner liner device 2 and an outer pressing device 3 fixed to a frame 1. The packaging box 7 is fastened to the inner liner device 2. When the outer pressing device 3 applies pressure to the fastener 8, the inner liner device 2 supports the fastener 8 inside the packaging box 7, and the outer pressing device 3 squeezes the fastener 8 outside the packaging box 7.
[0031] The following embodiments are further elaborated based on the above solutions. Example
[0032] Please refer to Figure 1-6 This embodiment provides a packaging box fastener repressing machine, which includes an inner liner device 2 and an outer pressing device 3 fixed to a frame 1, as well as a box placement plate 4 and a box picking robot fixed to the frame 1. The box placement plate 4 is located in front of the inner liner device 2 and is equipped with a box pushing device. The box pushing device drives the packaging box 7 to contact or detach from the inner liner device 2. An infeed conveyor belt and an outfeed conveyor belt are respectively installed on the left and right sides of the box placement plate 4. During production, the box picking robot grabs the packaging box 7 to be processed from the infeed conveyor belt and then places it on the box placement plate 4. The box pushing device pushes the packaging box 7 to fasten onto the inner liner device 2. Then, the outer pressing device 3 applies pressure to the fastener 8. Because the inner liner device 2 supports the fastener 8 inside the packaging box 7, the outer pressing device 3 squeezes the fastener 8 outside the packaging box 7 to complete the fastener repressing work. In this embodiment, the fasteners 8 on the packaging box 7 are repressed by the inner lining device 2 and the outer pressing device 3. Compared with the prior art, this can improve production efficiency and avoid deformation or damage to the paper packaging box 7.
[0033] For details, please refer to Figure 1-3 The inner lining device 2 is provided with an inner lining seat 21, and the inner lining seat 21 is provided with a support groove 22 for accommodating the support fastener 8. The support groove 22 is provided with a support block 23, and when the packaging box 7 is fastened to the inner lining seat 21, there is a gap between the fastener 8 and the support block 23. Since the fastener 8 includes a male and a female fastener, after the fastener 8 is installed on the box wall of the packaging box 7, the fastener 8 forms an outward protrusion on both the inner and outer sides of the box wall of the packaging box 7. Therefore, when the packaging box 7 is fastened to the inner lining seat 21, the support groove 22 not only avoids the fastener 8, preventing interference between the fastener 8 and the inner lining seat 21, but also, since there is a gap between the fastener 8 and the support block 23, when the external pressure device 3 presses the fastener 8, the support groove 22 can prevent the fastener 8 from displacing too much, ensuring that the fastener 8 can be subjected to sufficient pressing force and ensuring the re-pressing effect of the fastener 8.
[0034] It should be noted that the shape of the inner liner 21 is set as needed, and the position and number of the support grooves 22 are consistent with the position and number of the fasteners 8 on the packaging box 7. In order to improve the stability of the packaging box 7 during the re-pressing process, the shape of the inner liner 21 can be designed to match the shape of the packaging box 7. For example, in this embodiment, the packaging box 7 is a hexagonal prism box body, and the inner liner 21 is also a hexagonal prism structure. Moreover, the gap between the fasteners 8 and the support blocks 23 can be controlled within 2-4mm, and the gap value can also be set according to the toughness and other conditions of the packaging box 7.
[0035] In this embodiment, the lifting groove 22 is also provided with a guide groove 24. The width and depth of the guide groove 24 are both greater than the width and height of the part of the fastener 8 inside the packaging box 7. During the process of fastening the packaging box 7 to the inner liner seat 21, the part of the fastener 8 inside the packaging box 7 enters the lifting groove 22 through the guide groove 24.
[0036] In this embodiment, please refer to Figure 1-3 The external pressure device 3 includes an external pressure drive component and a pressure head 32. The external pressure drive component can be a hydraulic cylinder, a pneumatic cylinder, or other structure capable of driving the pressure head 32 to press the fastener 8. In this embodiment, the external pressure drive component is an external pressure cylinder 31, and the pressure head 32 is fixed on the external pressure cylinder 31. The external pressure cylinder 31 drives the pressure head 32 to apply pressure to the fastener 8. It should be noted that the number of external pressure devices 3 is consistent with the number of fasteners 8 on the packaging box 7. In this embodiment, the packaging box 7 is provided with three fasteners 8, therefore, there are three external pressure devices 3, and three lifting slots 22 are also provided.
[0037] In this embodiment, please refer to Figure 5 The box-pushing device includes a box-pushing cylinder 51, a box-pushing plate 52, and a box-pushing channel 53. The box-pushing channel 53 is composed of a pair of limiting plates 531 fixed to the box-placement plate 4. The packaging box 7 can only move in the channel between the two limiting plates 531. The box-pushing cylinder 51 is fixed on the box-placement plate 4. The box-pushing plate 52 is connected to the box-pushing cylinder 51. The box-pushing plate 52 is provided with a negative pressure suction cup for adsorbing the packaging box 7. The negative pressure suction cup is connected to the external negative pressure. When the packaging box 7 is placed in the box-pushing channel... At time 53, the pusher plate 52 sucks up the packaging box 7 and pushes it forward, moving the packaging box 7 along the pusher channel 53 until the packaging box 7 is covered and fastened on the inner liner seat 21. During the repressing process, the pusher cylinder 51 remains extended, and the negative pressure suction cup remains in a negative pressure adsorption state. After the repressing is completed, the pusher cylinder 51 retracts, the pusher plate 52 lifts the packaging box 7 away from the inner liner seat 21, and then the negative pressure suction cup stops the negative pressure adsorption state, waiting for the box-picking robot to grab and transfer it.
[0038] In this embodiment, please refer to Figure 1 and Figure 4The box-retrieving robot in this embodiment includes a lateral movement mechanism 61, a lifting mechanism, a vacuum nozzle 64, and a pre-positioning plate 65. The lateral movement mechanism 61 is fixed on the frame 1 and uses a lead screw driven by a servo motor. The lifting mechanism is connected to the lead screw, and the left and right lateral movement of the lifting mechanism is realized through the lead screw. The lifting mechanism includes a lifting cylinder 62 and a nozzle connector 63 installed on the lifting cylinder 62. The lifting cylinder 62 is connected to the lateral movement mechanism 61. The vacuum nozzle 64 is installed on the nozzle connector 63. The lifting mechanism is also provided with a pre-positioning plate 65. In this embodiment, the pre-positioning plate 65 is fixed to the nozzle connector 63 and forms a V-shape, which is adapted to the hexagonal prism-shaped packaging box 7. The lifting cylinder 62 is initially positioned on one side of the box-feeding conveyor belt. When the box-retrieving robot has only one retrieval station, during the retrieval process, the lateral movement mechanism 61 drives the lifting cylinder 62 to extend downwards, grabbing the packaging box 7 to be repressed from the box-feeding conveyor belt. The pre-positioning plate 65 ensures that the vacuum nozzle 64 faces and can hold the top surface of the packaging box 7. After the packaging box 7 is held by the vacuum nozzle 64, the lifting cylinder 62 retracts upwards, the lateral movement mechanism 61 drives the lifting cylinder 62 to move to the right, and then the lifting cylinder 62 extends downwards again, placing the packaging box 7 on the box-placement plate 4. Then, the negative pressure of the vacuum nozzle 64 is disconnected, releasing the packaging box 7. The lifting cylinder 62 retracts upwards to reset, waiting for the next retrieval. When the box-retrieving robot has two retrieval stations, such as... Figure 4 As shown, during the box retrieval process, the lateral movement mechanism 61 drives the lifting cylinder 62 to extend downwards, grabbing the packaging box 7 to be repressed from the box-in conveyor belt, and simultaneously grabbing the packaging box 7 that has already been repressed in the box-pushing channel 53. When the two packaging boxes 7 are sucked by the vacuum nozzle 64, the lifting cylinder 62 retracts upwards, the lateral movement mechanism 61 drives the lifting cylinder 62 to move to the right, and then the lifting cylinder 62 extends downwards again, placing the packaging box 7 to be processed on the box-placing plate 4, and simultaneously placing the repressed packaging box 7 on the box-out conveyor belt. Then the negative pressure of the vacuum nozzle 64 is disconnected, releasing the packaging box 7, and the lifting cylinder 62 retracts upwards to reset, waiting for the next box retrieval. By setting up a dual-station box-retrieval robot, efficiency can be further improved.
