Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to a self-adhesive labeling machine. Background Technology

[0002] A labeling machine is a device that affixes rolls of self-adhesive labels (paper or metal foil) to PCBs, products, or prescribed packaging. Labeling machines are an indispensable component of modern packaging. The variety of labeling machines produced in my country is gradually increasing, and the technological level has also greatly improved. The industry has shifted from the outdated manual and semi-automatic labeling methods to a market dominated by automated, high-speed labeling machines.

[0003] Existing self-adhesive labeling machines generally do not have a device to restrict the position of the object to be labeled, causing the object to shift during the conveying process, resulting in inaccurate labeling. Some restricting devices have their lower ends slidingly connected to the conveyor belt, and the friction generated by the connection is extremely large, affecting the service life of the device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies. By moving the lead screw sleeve to drive the connecting plate to move, the moving plate moves back and forth above the conveyor belt, thus pushing the object and keeping it in the middle of the conveyor belt, ensuring the accuracy of the labeling position. This invention provides a self-adhesive labeling machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-adhesive label applicator includes a base with a transmission groove at its upper end. The label applicator body is located at the upper end of the base. The transmission groove extends through the label applicator body. Two symmetrically arranged transmission rods are rotatably connected between the transmission groove and the base. A conveyor belt is rotatably connected between the two transmission rods. Two symmetrically arranged movable plates are located above the conveyor belt. Two horizontal plates are provided on opposite sides of each of the two movable plates. Multiple equally spaced support rollers are rotatably connected between the two horizontal plates on the same side. A connecting mechanism for connecting the movable plates is located at the upper end of the base, and a support mechanism for supporting the movable plates is located at the lower end of the movable plates.

[0007] Preferably, the connecting mechanism includes two symmetrically arranged fixed plates disposed on the upper end of the base, and two symmetrically arranged through rods are slidably connected through each of the two fixed plates, with the two through rods on the same side being connected to the side wall of the movable plate.

[0008] Preferably, the support mechanism includes multiple equally spaced roller grooves formed at the lower end of the moving plate, and each of the multiple roller grooves is connected to a ball bearing in a rolling manner, the ball bearing being in a rolling connection with the conveyor belt.

[0009] Preferably, a rotating rod is rotatably connected to the side wall of the fixed plate, a reciprocating screw area is provided on the outer wall of the rotating rod, a screw sleeve that cooperates with the reciprocating screw area is provided in the reciprocating screw area, a connecting plate is provided on the outer wall of the screw sleeve, and the end of the through rod is connected to the side wall of the connecting plate.

[0010] Preferably, the base has two fixing blocks at its front end, and a drive shaft is rotatably connected between the two fixing blocks. The outer walls of both ends of the drive shaft are provided with worm gears, and the outer walls of the two transmission rods are provided with worm wheels that cooperate with the worm gears. One of the fixing blocks has a support plate on its side wall, and a power motor is provided at the upper end of the support plate. One end of the drive shaft is connected to the end of the output shaft of the power motor.

[0011] Preferably, the outer walls of both ends of the transmission rod on the left side and the outer walls of the two rotating rods are provided with synchronous pulleys, and the two synchronous pulleys on the same side are connected by a synchronous belt drive.

[0012] The beneficial effects of this utility model are:

[0013] 1. By moving the lead screw sleeve, the connecting plate moves, which in turn causes the moving plate to move back and forth above the conveyor belt, thus pushing the object and keeping it in the middle of the conveyor belt to ensure the accuracy of the labeling position.

[0014] 2. By setting multiple ball bearings in the grooves at the lower end of the moving plate, the ball bearings are connected to the conveyor belt in a rolling manner, changing the sliding connection between the moving plate and the conveyor belt into a rolling connection, thereby reducing friction and improving the service life of the device.

[0021] Reference Figure 1-3 A self-adhesive label applicator includes a base 1, a transmission groove 2 at the upper end of the base 1, a label applicator body 5 at the upper end of the base 1, the transmission groove 2 passing through the label applicator body 5, two symmetrically arranged transmission rods 3 rotatably connected between the transmission groove 2 and the base 1, a conveyor belt 4 rotatably connected between the two transmission rods 3, two symmetrically arranged movable plates 8 above the conveyor belt 4, two horizontal plates 9 on opposite sides of the two movable plates 8, and multiple equally spaced support rollers 11 rotatably connected between the two horizontal plates 9 on the same side, and a connecting mechanism for connecting the movable plates 8 at the upper end of the base 1, the connecting mechanism including two symmetrically arranged fixed plates 6 at the upper end of the base 1, two symmetrically arranged through rods 7 slidably connected to the two fixed plates 6, and the two through rods 7 on the same side being connected to the side wall of the movable plate 8.

[0022] The lower end of the movable plate 8 is provided with a support mechanism for supporting it. The support mechanism includes multiple equally spaced roller grooves 22 on the lower end of the movable plate 8. Roller balls 23 are rolled in each of the multiple roller grooves 22. The roller balls 23 are rolled in connection with the conveyor belt 4. By setting the roller balls 23 in the multiple roller grooves 22 on the lower end of the movable plate 8, the roller balls 23 are rolled in connection with the conveyor belt 4, changing the sliding connection between the movable plate 8 and the conveyor belt 4 to a rolling connection, thereby reducing friction and improving the service life of the device.

[0023] A rotating rod 12 is rotatably connected to the side wall of the fixed plate 6. A reciprocating screw area 13 is provided on the outer wall of the rotating rod 12. A screw sleeve 14 that cooperates with it is provided in the reciprocating screw area 13. A connecting plate 15 is provided on the outer wall of the screw sleeve 14. The end of the through rod 7 is connected to the side wall of the connecting plate 15. By moving the screw sleeve 14, the connecting plate 15 is moved, thereby driving the moving plate 8 to move back and forth above the conveyor belt 4. Thus, the object is pushed and kept in the middle of the conveyor belt 4, ensuring the accuracy of the labeling position.

[0024] The base 1 has two fixed blocks 16 at the front end, and a drive shaft 17 is rotatably connected between the two fixed blocks 16. Both ends of the drive shaft 17 have worm gears 18 on their outer walls, and both transmission rods 3 have worm wheels 19 on their outer walls that cooperate with the worm gears 18. One of the fixed blocks 16 has a support plate on its side wall, and a power motor 21 is provided at the upper end of the support plate. One end of the drive shaft 17 is connected to the end of the output shaft of the power motor 21.

[0025] Synchronous pulleys 20 are provided on the outer walls of both ends of the left transmission rod 3 and the outer walls of the two rotating rods 12. The two synchronous pulleys 20 on the same side are connected by a synchronous belt drive.

[0026] When using this invention, when applying self-adhesive labels to objects (since the labeling machine body 5 is existing technology, its related structure is not described in detail in this drawing), the object is placed on the upper end of the conveyor belt 4, and the power motor 21 is started, which drives the drive shaft 17 to rotate, causing the worm gears 18 at both ends of the drive shaft 17 to rotate. Utilizing the cooperation between the worm gears 18 and the worm wheel 19, the two transmission rods 3 rotate, driving the conveyor belt 4 to transmit the object. During the transmission process, the synchronous pulley 20 and synchronous belt between the transmission rods 3 and the rotating rods 12 cause the two rotating rods 12 to rotate synchronously, thus causing the reciprocating screw area 13 on the outer wall of the rotating rods 12 to rotate. Utilizing the cooperation between the reciprocating screw area 13 and the screw sleeve 14, as well as the penetrating action of the two through rods 7, the screw sleeve 14 moves, driving the connecting plate 15 to move, thereby causing the moving plate 8 to move back and forth above the conveyor belt 4, thus achieving the pushing of the object and keeping the object always in the middle of the conveyor belt 4, ensuring the accuracy of the labeling position.

[0027] By setting multiple rolling balls 23 in the multiple rolling grooves 22 at the lower end of the moving plate 8, the rolling balls 23 are connected to the conveyor belt 4 in a rolling connection, changing the sliding connection between the moving plate 8 and the conveyor belt 4 to a rolling connection, thereby reducing friction and improving the service life of the device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
