Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0045] like Figure 1 As shown in the figure, this application embodiment provides a gluing machine capable of screening out boxes with unacceptable viscosity. This gluing machine includes a first conveyor 1, a viscosity meter 2, a material removal mechanism 3, a second conveyor 4, a recycling bin 5, and a finished product bin 6. The first conveyor 1 is used to transport glued paper boxes 8. The viscosity meter 2 is connected to the first conveyor 1 and located above it to detect the viscosity of the paper boxes 8. The material removal mechanism 3 is connected to the first conveyor 1 and is used to grab paper boxes 8 with unacceptable viscosity. The material removal mechanism 3 is located directly above the first conveyor 1 and along the conveying direction of the first conveyor line. The material removal mechanism 3 is located behind the viscosity meter 2 and is equipped with a... A fixed spacing is maintained; the second conveyor 4 is connected to the first conveyor 1 via a recycling support frame 9. The second conveyor 4 is used to transport the cardboard boxes 8 gripped by the material removal mechanism 3. Since the material removal mechanism 3 is located above the first conveyor line, the second conveyor line is also located above the first conveyor line to facilitate receiving the cardboard boxes 8 gripped by the material removal mechanism 3. The recycling bin 5 is used to receive the cardboard boxes 8 on the second conveyor 4. The finished product bin 6 is used to receive the cardboard boxes 8 on the first conveyor 1. The finished product bin 6 is equipped with a third conveyor 7. Since the space above is occupied by the second conveyor line and the recycling bin 5, the setting of the third conveyor 7 can transport the finished product bin 6 to the side position for easy handling by workers.

[0046] In some alternative embodiments, such as Figures 2-3As shown, the material removal mechanism 3 includes a connecting shaft 31, an air distribution plate 32, and a gripping assembly 33. The connecting shaft 31 is connected to the first conveyor 1 via brackets. There are two brackets, which are respectively connected to both sides of the length of the first conveyor line. The two ends of the connecting shaft 31 are rotatably connected to the brackets, so that the connecting shaft 31 can rotate freely on the brackets. The connecting shaft is equipped with a drive motor to realize the automatic rotation of the connecting shaft 31. The connecting shaft 31 has a ventilation channel, which is formed by a blind hole coaxially opened from one end of the connecting shaft 31. The air distribution plate 32 is connected to the connecting shaft 31 to rotate synchronously. The air distribution plate 32 has multiple air distribution channels 322 communicating with the ventilation channels. Each air distribution channel 322 can be filled with air by a solenoid valve 323. In actual implementation, the air passage opening and closing control involves multiple through holes formed radially along the wall of the air passage from the connecting shaft 31. These through holes correspond to the positions of multiple air distribution channels 322 on the air distribution plate 32, thereby achieving communication between the air passage and the air distribution channel 322. Multiple gripping components 33 are connected to the air distribution plate 32 via connecting seats 34 and are evenly distributed around the axis of the connecting shaft 31. When the connecting shaft 31 rotates, the multiple gripping components 33 can operate continuously in a cycle. The gripping components 33 cooperate with the air distribution channels 322 to achieve gripping action through negative pressure. This indicates that the gripping components 33 are pneumatically driven components. In actual implementation, connecting the negative pressure generating device to the air passage on the connecting shaft 31 can deliver pneumatic driving force.

[0047] In some alternative embodiments, such as Figures 4-5 As shown, the gripping assembly 33 includes a support cylinder 331, a piston rod 332, an electromagnet 334, an elastic element 335, and a suction cup 333. The support cylinder 331 is connected to the air distribution plate 32 via a connecting seat 34. The support cylinder 331 has an air passage that connects the internal space with the air distribution channel 322. The piston rod 332 is movably inserted into the support cylinder 331. One end of the piston rod 332 is connected to a magnetic adsorption element 338. The piston rod 332 has an axially penetrating air passage 337, which communicates with the air passage to form an air path. The electromagnet 334 is located inside the support cylinder 331 and is spaced apart from the piston rod 332. The elastic element 335 is located between the piston rod 332 and the electromagnet 334 and is connected to both the piston rod 332 and the electromagnet 334. The suction cup 333 is connected to the piston rod 332.

[0048] In this embodiment, the piston rod 332 can be extended by the elastic force of the elastic element 335, so that the suction cup 333 on the piston rod 332 contacts the paper box 8. Under the elastic force of the elastic element 335, a contact pressure is formed between the suction cup 333 and the paper box 8. The suction cup 333 is attracted to the paper box 8 by the negative pressure generating device. Then, the magnetic force of the electromagnet 334 attracts the magnetic adsorption element 338 to retract the piston rod 332, thereby driving the paper box 8 to leave the first conveyor line. Then, the connecting shaft 31 rotates to drive the paper box 8 to move, and finally the paper box 8 is transported to the second conveyor 4.

[0049] In some alternative embodiments, the elastic element 335 is configured as a helical spring, wherein a buffer sleeve is fitted onto the helical spring.

[0050] In this embodiment, the conveying speed of the first conveyor 1 is relatively fast. If the piston rod 332 does not retract in time, the front and rear paper boxes 8 are prone to collide. Therefore, the starting current of the electromagnet 334 is generally large so that the piston rod 332 can retract quickly. At this time, the helical spring will contract quickly. Under the action of inertia, the helical spring may contract excessively and cause a rebound phenomenon, which will cause the piston rod 332 to vibrate axially. By putting a buffer sleeve on the helical spring, a certain buffer can be provided to avoid the piston rod 332 from vibrating and reduce the risk of the paper box 8 falling. In actual implementation, the buffer sleeve can be a rubber sleeve.

[0051] In some alternative embodiments, the air passage is connected to the airway via a corrugated flexible tube 336.

[0052] In this embodiment, there is a large space between the electromagnet 334 and the magnetic adsorption component 338. At the moment the negative pressure generating device is started, the space between the electromagnet 334 and the magnetic adsorption component 338 will contract slightly. This will cause the piston rod 332 to retract axially, thereby reducing the contact pressure between the suction cup 333 and the paper box 8, and making it easy for adsorption to fail. By setting the elastic bellows, the air passage 337 can be connected to the air passage, and the space between the electromagnet 334 and the magnetic adsorption component 338 can be isolated, thereby ensuring the stability of the piston rod 332 when the negative pressure generating device is started. At the same time, during the retraction process of the piston rod 332, the elastic force of the elastic bellows acts on the piston rod 332 to work in conjunction with the elastic component 335, further providing buffering.

[0053] In some alternative embodiments, the connector 34 has a sealing ring that can enclose the air distribution channel 322; this arrangement can ensure the sealing of the connection between the connector 34 and the air distribution channel 322, thereby ensuring that the suction cup 333 has the expected adsorption force on the paper box 8.

[0054] In some alternative embodiments, the connector 34 has a countersunk hole and is bolted to the gripping assembly 33.

[0055] In some alternative embodiments, such as Figure 6 As shown, the recycling support frame 9 includes a first sub-frame 91 and a second sub-frame 92; the first sub-frame 91 is connected to the first conveyor 1 through a support truss 94; the second sub-frame 92 is connected to the first conveyor 1 through a support truss 94, and the first sub-frame 91 and the second sub-frame 92 are located on both sides of the length direction of the first conveyor 1; wherein, two second conveyors 4 are respectively installed on the first sub-frame 91 and the second sub-frame 92.

[0056] In this embodiment, a certain gap is formed between the two second conveyors 4, which can avoid the gripping component 33. Thus, when the gripping component 33 rotates between the two second conveyors 4, the corresponding air path can be directly cut off, so that the cardboard box 8 on it falls directly onto the two second conveyors 4.

[0057] In some alternative embodiments, a support plate 93 is connected to the recycling support frame 9, and the recycling box 5 is placed on the support plate 93.

[0058] In some alternative embodiments, a friction layer is attached to the support plate 93. This configuration can improve the stability of the recycling bin 5 on the support plate 93 and eliminates the need for connection, making it easy to pick up and put down.

[0059] Working principle: The recycling bin 5 and finished product bin 6 are placed in position, and the negative pressure generating device is connected to the material removal mechanism 3. The material removal mechanism 3, the first conveyor line, the second conveyor line, the third conveyor line, and the viscosity meter 2 are all controlled by the controller. In the initial state, the solenoid valves 323 in the material removal mechanism 3 are all closed by the controller, and the electromagnet 334 is controlled by the controller to retract the piston rod 332. The connecting shaft 31 is controlled by the controller to rotate so that one of the gripping components 33 is in a vertical state. The viscosity meter 2 is controlled by the controller to detect the viscosity of the cardboard box 8. When a cardboard box 8 with unqualified viscosity is detected, the electromagnet 334 is controlled by the controller to stop working, and the piston rod 332 extends under the elastic force of the elastic element 335, causing the suction cup 333 to abut against the cardboard box 8. The negative pressure generating device and the corresponding solenoid valves 323 are controlled by the controller. When the controller is opened, the vertical gripping component 33 grips the cardboard box 8. The electromagnet 334 inside is controlled by the controller to retract the piston rod 332. The connecting shaft 31 is controlled by the controller to rotate so that the adjacent gripping component 33 is in a vertical position to prepare for gripping. When the gripping component 33 with the cardboard box 8 is driven to the second conveyor 4, the gripping component 33 will pass between the two second conveyors 4. The negative pressure generating device is controlled by the controller to shut down. At this time, the cardboard box 8 on it will fall onto the second conveyor 4. The second conveyor 4 will transport the cardboard box 8 with unqualified viscosity to the recycling box 5. The cardboard box 8 with qualified viscosity will be received by the finished product box 6. When the finished product box 6 is full, the third conveyor 7 is controlled by the controller to move the full finished product box 6 one box position away. Then the next empty finished product box 6 will continue to receive the cardboard box 8 with qualified viscosity.

[0060] In summary, the gluing machine provided in this application can screen out paper boxes 8 with unqualified viscosity. By setting the viscosity detector 2, it can detect paper boxes 8 with unqualified viscosity. Then, the material removal mechanism 3 grabs the paper boxes 8 with unqualified viscosity and transports them to the recycling bin 5 via the second conveyor 4. Paper boxes 8 with qualified viscosity are collected by the finished product bin 6, thereby realizing the automatic separation of qualified paper boxes 8 and unqualified paper boxes 8. It can eliminate the need for workers to perform viscosity quality inspection of paper boxes 8 and save the work of sorting unqualified paper boxes 8, which is conducive to improving the production efficiency of paper boxes 8 and reducing the labor intensity of workers.
