Description

Technical Field

[0001] The utility model relates to the technical field of automatic labeling machines, in particular to a pressing structure of an automatic labeling injection machine. Background Art

[0002] The automatic labeling and injection machine is a device for the production and processing of CD boxes. Usually, after the CD box is produced by the mold, screws or positioning parts need to be pressed into the two sides of the CD box close to the rotating shaft at the bend of the CD box, and then the label is affixed. This can make the CD box take shape and have a certain hardness. After the CD box is formed, it also needs to be labeled according to the situation to facilitate subsequent identification.

[0003] When the CD box moves on the conveyor belt, in order to increase the tightness of the connection between the label and the CD box, the pressing structure of the label is usually pressed against the CD box, which makes the position of the CD box move less precise, resulting in deviation during labeling.

[0004] According to the "Elastic Pressing Structure of an Automatic Labeling Machine" with Chinese Patent Publication No. CN216375393U, it mainly describes that through the motor provided, the elastic pressing structure of the automatic labeling machine starts the motor when working, drives the half gear to rotate, and when the half gear contacts the rack, drives the rack to rotate. Since the rack and the slider are fixedly connected, the slider is driven to slide inside the slide groove, and then pushes the pressing device to press the label. When the half gear leaves the rack, the slider returns to its original position under the drive of the second spring. This is repeated to achieve automatic pressing of the label, solving some defects of the existing labeling machine. After the label is affixed, it needs to be pressed, otherwise the label is easy to fall off, resulting in the product being unable to be distinguished. At present, when pressing the label, most of the time it is manually pressed, which is not only time-consuming and labor-intensive, but also increases production costs and cannot meet production requirements. In this process, the label position on the CD box is easily offset, resulting in poor labeling effect.

[0005] Therefore, a pressing structure of an automatic labeling injection machine is proposed to solve the problem that the labeling position on the CD box is easily offset during the process, resulting in poor labeling effect. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to Figure 1-3The pressing structure of an automatic labeling and injection machine shown in the figure includes a support plate 1, a rotating roller 2, a conveyor belt 3, a feeding roller 5, a material roll 6, a label 7 and a receiving roller 10, and is characterized in that the upper end of the support plate 1 is fixedly connected to a support frame 4, and one side of the support frame 4 is fixedly connected to a first motor. The first motor drives the feeding roller 5 to rotate, which can move the material roll 6 and the label 7. The output end of the first motor is fixedly connected to the feeding roller 5, and one side of the support frame 4 is rotatably connected to a limiting roller 8. One side of the material roll 6 is in contact with a pressure strip 9, and the pressure strip 9 is a triangular structure. By setting the pressure strip 9, when the label 7 and the material roll 6 move to the tip of the pressure strip 9, they are subjected to pressure, and the label 7 is separated from the material roll 6. Then, the air pump 15 is started to make the connecting frame 13 in a negative pressure state, and cooperate with the through hole 16 to make the air inlet 12 suck Air is pressed, and one side of the label 7 contacts the pressure roller 11. Then, under the rotation of the pressure roller 11, the label 7 moves with the rotation of the pressure roller 11, so as to be stably connected to the CD box. The pressure strip 9 is fixedly connected between the two support plates 1, and the limiting roller 8 contacts the label 7. One side of the label 7 contacts the pressure roller 11 (one side of the pressure roller 11 is connected to the driving motor and only serves as a driving source). The pressure roller 11 is driven by the driving motor to rotate, so that the label 7 can be fitted to the CD box. Air inlet holes 12 are evenly provided on the pressure roller 11, and one end of the pressure roller 11 is fixedly connected to a connecting shaft and a through hole 16 is provided on the connecting shaft. A connecting frame 13 is fixedly connected to one side of the support plate 1, and an air pump 15 is fixedly connected to one side of the upper end of the connecting frame 13. The connecting frame 13 is communicated with the inside of the connecting shaft, and the connecting shaft is rotatably connected to the support plate 1 through a sealed bearing 14.

[0020] Among them, the pressure roller 11 corresponds to the pad roller 17, the conveyor belt 3 contacts the pad roller 17, and the pad roller 17 rotates to connect the support plate 1. By arranging the pad roller 17 to provide support for the pressure roller 11 on the bottom side of the conveyor belt 3, it is convenient to limit the CD box and improve the stability during labeling.

[0021] Among them, the auxiliary strip 19 is fixedly connected to the output end of the second motor, and the second motor is fixedly connected to the upper end of the support plate 1. By setting the auxiliary strip 19, when the CD box moves to the label 7, it rotates to form a right-angle structure with the support plate 1, thereby achieving the effect of adjusting the position of the CD box and improving the accuracy of labeling.

[0022] Among them, a hidden groove 18 is opened on the support plate 1, and the auxiliary strip 19 is located in the hidden groove 18. By setting the hidden groove 18, the auxiliary strip 19 can be easily hidden, thereby preventing the auxiliary strip 19 from affecting the movement of the CD box.

[0023] Among them, the conveyor belt 3 is in contact with the auxiliary roller 22, the auxiliary roller 22 is rotatably connected to the two sliders 21, the slider 21 is fixedly connected to the output end of the electric push rod 20, and the electric push rod 20 is fixedly connected to the upper side of the first groove of the support plate 1. The first groove is located on the opposite side of the two support plates 1. By setting the auxiliary roller 22, it can assist in compacting the label 7 on the CD box.

[0024] The two support plates 1 are fixedly connected to a support bar 23 , and the support bar 23 contacts one side of the conveyor belt 3 . By providing the support bar 23 , the stability of labeling is improved.

[0025] Working principle: Put the material roll 6 on the unloading roller 5, and make the label 7 face the side of the pressure roller 11, then the rotation of the conveyor belt 3 drives the CD box to move, and when the CD box moves to the bottom side of the pressure roller 11, start the second motor and drive the auxiliary strip 19 to rotate, so that the auxiliary strip 19 is perpendicular to the support plate 1, adjust the position of the CD box, and improve the labeling accuracy. The driving motor drives the pressure roller 11 to rotate, and starts the air pump 15 so that the air inlet 12 can pull the single label 7, and then the pad roller 17 and the support strip 23 provide support, and the pressure roller 11 rotates to cooperate with the movement of the CD box to provide the label 7 connection, and then the electric push rod 20 extends to drive the slider 21 and the auxiliary roller 22 to press the CD box with the label 7 again to improve the pressing effect.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
