[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-6 The utility model provides a technical solution: an automatic flat labeling machine comprising: a conveyor belt 1, a front end of the outer side of the crawler of the conveyor belt 1 is connected to a reset bracket 2 in an array shape, a push rod 3 is inserted into the interior of the reset bracket 2, the front end of the push rod 3 is connected to a push plate 4, the rear end of the push rod 3 is connected to a push block 5, a reset spring 6 is connected to the outer surface of the push rod 3 and located between the reset bracket 2 and the push block 5, the frame on the left side of the front end of the conveyor belt 1 is in an outwardly sloping shape, the upper left end of the rear end of the conveyor belt 1 is connected to a label roll bracket 7, the conveyor belt 1 is connected to a label outlet bracket 12 on the upper right side, and the lower end of the inner portion of the label outlet bracket 12 is connected to a label outlet 13 through a threaded connection. The lower end of the label roll bracket 7 is connected to a winding roller 15, and the rear end of the winding roller 15 is connected to a motor 16. The right side of the front end of the conveyor belt 1 is connected to a controller 17, and the right side of the rear end of the conveyor belt 1 is connected to a distance sensor 18. An infrared transceiver sensor 19 is provided on the upper part of the conveyor belt 1 and on the left side of the label outlet bracket 12. The conveyor belt 1, the motor 16, the distance sensor 18, the infrared transceiver sensor 19 and the controller 17 are electrically connected.
[0024] When in use, the label roll is placed on the label roll bracket 7, one end of the label roll is pulled out and passed through the gap inside the infrared transceiver sensor 19, then one end of the label roll is passed through between the label outlet 13 and the label outlet bracket 12, and the label roll is tightly attached to the right side of the label outlet 13, and finally placed on the outside of the winding roller 15, the machine is started, and the speed of the conveyor belt 1 and the speed of the motor 16 are adjusted through the controller 17. When the packaging box (here the packaging box is used as the labeled product, and it can be replaced with other labeled products according to actual usage) is placed on the conveyor belt 1 manually or discharged from the conveyor belt outlet, the conveyor belt 1 moves to the right. At this time, the reset bracket 2 at the front end will move with the push rod 3, and when the push block 5 contacts the opening on the left side of the front end of the conveyor belt 1, it will push the push rod 3 backward. At this time, the push plate 4 will push the packaging box backward, and the push block 5 will contact the position parallel to the front end of the conveyor belt. The push plate 4 will push the packaging box to the rear end of the inner side of the conveyor belt 1, thereby clamping the packaging box. When it moves to the lower left end of the front end of the conveyor belt 1, the reset spring 6 will push the push block 5 to the front end, thereby resetting the push rod 3, push plate 4, and push block 5. When the packaging box moves to the lower end of the distance measuring sensor 18, the distance changes, and an electrical signal will be given to the controller 17. , start the motor 16, and the winding roller 15 is wound. When the label roll is at the position of the label outlet 13, there will be an acute angle, and the paper under the label is more flexible, but the flexibility of the label is not so good. At this time, the paper under the label will continue to move in the winding direction. The adhesive force at the bottom of the label is less than the force during bending, and the edge is lifted, so that the label is separated from the paper under the label, and the paper under the label roll will continue to be attached to the label outlet 13, and the label on the label roll will be separated and attached to the surface of the packaging box. At the same time, the label roll continues to be pulled, and the position with the label will block the infrared light of the infrared transceiver sensor 19, so that the infrared light cannot pass through the label. When it moves to the gap between the labels, the infrared light emitted by the infrared transceiver sensor 19 will be transmitted through the bottom paper to the receiving end, and an electrical signal will be sent to the controller 17 to turn off the rotation of the motor 16.
[0025] like Figure 1-6 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the upper end in the middle of the rear end of the conveyor belt 1 is connected to a first tensioning roller 9, the right side of the rear end of the conveyor belt 1 is connected to a first steering roller 10, the lower left end of the first steering roller 10 is connected to a second steering roller 11, the lower end of the first tensioning roller 9 is connected to a second tensioning roller 14, the label bracket 12 is located at the lower right end of the second steering roller 11, and the infrared transceiver sensor 19 is located between the first steering roller 10 and the second steering roller 11.
[0026] Analysis of the above structure shows that after the label roll is pulled out from the label roll holder 7, it passes through the lower end of the first tensioning roller 9, then passes through the upper end of the first deflection roller 10, passes through the left side of the second deflection roller 11, and then passes through the infrared transceiver sensor 19 and the interior of the label output holder 12. After passing through, the upper end of the second tensioning roller 14 is then sleeved on the outside of the winding roller 15. The first and second deflection rollers 10, 11 can penetrate the interior of the label output holder 12 and the label outlet 13 at a suitable angle to prevent the label from rubbing against the upper end of the label output holder 12 and falling off. The first and second tensioning rollers 9, 14 can maintain tension during unwinding and rewinding.
[0027] like Figure 1-6 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the push rod 3 includes: a lower push rod 31, an adjustment rod 32 and an upper push rod 33. The lower push rod 31 is fixedly connected to the push block 5, and the upper push rod 33 is fixedly connected to the push plate 4. The lower push rod 31, the adjustment rod 32 and the upper push rod 33 are connected by threads.
[0028] From the analysis of the above structure, it can be seen that when the total length of the push rod 3 needs to be adjusted, it is only necessary to replace the length of the middle adjustment rod 32 or remove the adjustment rod 32.
[0029] like Figure 1-5 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a clamping groove is opened on the outside of the winding roller 15, and a clamping plate 21 is connected to the outside of the winding roller 15 and at one end of the clamping groove through a spring hinge.
[0030] From the analysis of the above structure, it can be seen that by pulling the end of the label roll to the winding roller 15 and then placing it inside the clamping groove, and then closing the clamping plate 21, the end of the label roll can be clamped to prevent the label roll from loosening.
[0031] like Figure 1-6 As shown, an embodiment of the present invention provides an implementation method. Based on the above implementation method, arcs are provided on the left and right sides of the pushing block 5.
[0032] From the analysis of the above structure, it can be seen that the arc surfaces on the left and right sides of the pushing block 5 can reduce the friction between the outer frame of the conveyor belt 1 and the pushing block 5.
[0033] like Figure 1-5 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a slide groove is opened on the right side of the rear end of the conveyor belt 1 and on the left and right sides of the ranging sensor 18. A slider is connected to the lower end of the ranging sensor 18, and the slider is inserted and connected to the slide groove.
[0034] From the above structure, it can be seen that when the longitudinal position of the label paper on the packaging box needs to be adjusted, the distance measuring sensor 18 is slid left and right. At this time, the position change of the packaging box is detected, and the position of the label will also change.
[0035] like Figure 1-5 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, adjustment grooves are opened on the lower surface of the inner part of the label bracket 12 and the left and right sides of the label bracket 12. The upper end of the label outlet 13 is inserted into and connected with the inner part of the adjustment groove. The bolt at the upper end of the label outlet 13 passes through the adjustment groove and extends to the upper end of the label bracket 12.
[0036] From the analysis of the above structure, it can be seen that when the horizontal position of the label paper on the required labeled packaging box needs to be adjusted, loosen the nut on the upper end of the label outlet 13, slide the label outlet 13 inside the adjustment slide groove inside the label outlet bracket 12, adjust it to the required position, and then tighten the nut.
[0037] like Figure 1-5 As shown, an embodiment of the present invention provides an implementation method. Based on the above implementation method, the first tensioning roller 9, the first steering roller 10, the second steering roller 11 and the second tensioning roller 14 are all provided with a guide ring 22 on the outside.
[0038] From the analysis of the above structure, it can be seen that when the labeling position needs to be adjusted, the positions of the first tensioning roller 9, the first steering roller 10, and the guide ring 22 outside the first steering roller 10 and the second tensioning roller 14 are adjusted first to play a pre-guiding role so that the label paper is parallel to the label outlet 13.
