Abstract
Description
Technical Field
[0001] This utility model relates to the field of explosives production technology, specifically to an online automatic labeling machine for paper-plastic bags. Background Technology
[0002] Emulsion explosives generally refer to a class of industrial explosives prepared using emulsification technology, in which microdroplets of an oxidizing agent salt aqueous solution are uniformly dispersed in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres, forming a water-in-oil emulsion-like aqueous industrial explosive, such as common detonators. Their outer packaging is mostly paper-plastic packaging. Detonators are mostly cylindrical. After production, corresponding production labels need to be affixed to the outer packaging. However, the labels on cylindrical explosives cannot adhere well to the explosives and are easy to fall off. In order to improve this situation, an online automatic labeling machine for paper-plastic bags is proposed.
[0003] For example, a labeling machine disclosed in the authorization announcement number CN218877857U includes a support frame, on each of the upper two sides of the support frame a transmission roller, and the two transmission rollers are connected by a transmission belt. The end of one of the transmission rollers is fixedly connected to the output shaft of a servo motor by a key, and the servo motor is fixed at the front upper part of the support frame.
[0004] Although it is simple and convenient for staff to operate, it not only meets the labeling needs of products of different widths, but also allows labels on a large number of products to be in close alignment, ensuring labeling quality. It can also meet the labeling needs of products of different heights, effectively expanding the scope of application, and makes the labels firmly adhered to the products, making it easy to replace the wheel with a new label tape.
[0005] However, the existing labeling machines do not solve the problems of not being able to center and clamp emulsion explosives to prevent displacement, not being able to automatically and sequentially apply labels to emulsion explosives, and not being able to roll and press the labels to prevent them from falling off, which affects the quality of label application. Utility Model Content
[0006] The purpose of this utility model is to provide an online automatic labeling machine for paper and plastic bags, so as to solve the problems mentioned in the background art, which are that the labeling machine is not convenient for centering and clamping emulsion explosives to prevent the explosives from shifting, and is not conducive to automatically pasting labels onto emulsion explosives in sequence and rolling and pressing the labels to prevent them from falling off, thus affecting the quality of label application.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an online automatic labeling machine for paper and plastic bags, comprising a belt conveyor and a support plate. The support plate is installed at the top of the belt conveyor, and a connecting plate is provided on the side wall of the support plate. A cylinder is installed on the side wall of the connecting plate, and a first push arm is installed at the output end of the cylinder. A lower pressure frame is installed at the bottom end of the first push arm, and a lower pressure roller is provided inside the lower pressure frame, and the lower pressure roller is movably connected to the lower pressure frame. Electric push rods are symmetrically installed on the side wall of the belt conveyor, and a second push arm is installed at the output end of each electric push rod. Clamping blocks are provided on the surface of each second push arm. A placement roller is provided on the side wall of the support plate on one side of the connecting plate.
[0008] Preferably, a limiting roller is provided on the side wall of the support plate on one side of the placement roller, and the limiting roller is movably connected to the support plate.
[0009] Preferably, a drive roller is provided on the side wall of the support plate on one side of the limiting roller, and the drive roller is movably connected to the support plate.
[0010] Preferably, extrusion rollers are movably mounted on the sidewalls of the support plates on both sides of the drive roller, a stepper motor is provided on the sidewall of the support plate on one side of the drive roller, and a placement plate is provided on the sidewall of the support plate on the side of the stepper motor.
[0011] Preferably, the output end of the stepper motor is equipped with a drive shaft, the surface of the drive shaft is provided with a first pulley assembly, and the first pulley assembly is connected to the drive roller.
[0012] Preferably, the surface of the drive roller is provided with a second pulley assembly, and the second pulley assembly is connected to the limiting roller.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the labeling machine not only realizes the centering and clamping of emulsion explosives to prevent the explosives from shifting, but also facilitates the automated sequential pasting of labels on emulsion explosives and the rolling and pressing of the labels to prevent them from falling off, but also improves the quality of label application.
[0014] (1) The cylindrical emulsion explosive is sequentially conveyed to the space between two sets of clamping blocks via a belt conveyor. The second push arm is moved by an electric push rod, which in turn moves the two sets of clamping blocks closer together and clamps and fixes the emulsion explosive. The drive shaft is rotated by a stepper motor, which in turn drives the drive roller to rotate via the first pulley assembly. The drive roller drives the limiting roller to rotate via the second pulley assembly. Under the limiting cooperation of the two sets of squeezing rollers, the drive roller moves the label paper. The label paper moves on the surface of the limiting roller, the placement roller, and the placement plate. Because one end of the placement plate is designed with a blade, when the label paper moves over it, the edge of the label paper will... As the backing paper moves, the label gradually detaches from the backing paper and adheres to the emulsion explosive. At this point, the electric push rod is turned off, and the belt conveyor moves the emulsion explosive. During the movement of the emulsion explosive, the label adheres to the surface of the emulsion explosive. The above operation is repeated to automatically attach labels to the emulsion explosive sequentially. The limiting cooperation between the drive roller and the squeeze roller ensures that the label remains taut during movement and retraction, making it easier for the label to detach from the backing paper. This achieves centering and clamping of the emulsion explosive to prevent displacement and facilitates the automated sequential labeling of the emulsion explosive.
[0015] (2) When the label is stuck on the emulsion explosive, since the emulsion explosive is cylindrical, the label cannot be completely attached to the explosive. The cylinder drives the first push arm to move, and the first push arm drives the lower pressure frame and the lower pressure roller to move, so that the lower pressure roller contacts the label. The friction between the explosive and the belt conveyor is greater than the friction between the lower pressure roller and the label. The belt conveyor can drive the explosive to continue moving, and the explosive drives the lower pressure roller to rotate. The lower pressure roller rolls and presses the label, making the label adhere more tightly to the explosive, thus completing the labeling operation of the emulsion explosive. This facilitates rolling and pressing the label to prevent it from falling off and improves the adhesion between the label and the explosive. Attached Figure Description

[0025] Example 1
[0026] Please see Figure 1-5An embodiment of this utility model provides an online automatic labeling machine for paper and plastic bags, including a belt conveyor 1 and a support plate 3. The support plate 3 is installed at the top of the belt conveyor 1. A connecting plate 4 is provided on the side wall of the support plate 3. A cylinder 10 is installed on the side wall of the connecting plate 4. The cylinder 10 plays a power driving role. A first push arm 11 is installed at the output end of the cylinder 10. A lower pressure frame 12 is installed at the bottom end of the first push arm 11. A lower pressure roller 13 is provided inside the lower pressure frame 12, and the lower pressure roller 13 is movably connected to the lower pressure frame 12. Electric push rods 18 are symmetrically installed on the side wall of the belt conveyor 1. The electric push rods 18 play a power driving role. A second push arm 19 is installed at the output end of each electric push rod 18. A clamping block 17 is provided on the surface of each second push arm 19. A placement roller 16 is provided on the side wall of the support plate 3 on one side of the connecting plate 4.
[0027] Cylindrical emulsion explosives are sequentially conveyed by belt conveyor 1 to the space between two sets of clamping blocks 17. The electric push rod 18 is activated, causing the second push arm 19 to move. The second push arm 19 then moves the two sets of clamping blocks 17 closer together, clamping and fixing the emulsion explosives. The stepper motor 15 is activated, causing the drive shaft 5 to rotate. The drive shaft 5, through the first pulley assembly 6, drives the drive roller 9 to rotate. The drive roller 9, through the second pulley assembly 7, drives the limiting roller 8 to rotate. Under the limiting cooperation of the two sets of squeezing rollers 14, the drive roller 9 moves the label paper. The label paper moves on the surfaces of the limiting roller 8, the placement roller 16, and the placement plate 2. Because one end of the placement plate 2 has a blade-like design, As the label paper moves over it, the edges of the label paper will curl up, and as the backing paper moves, the label paper will gradually fall off the backing paper and stick to the emulsion explosive. At this time, the electric push rod 18 is turned off, and the belt conveyor 1 drives the emulsion explosive to move. During the movement of the emulsion explosive, the label paper sticks to the surface of the emulsion explosive. After repeating the above operation, the emulsion explosive can be automatically labeled in sequence. The limiting cooperation between the drive roller 9 and the squeeze roller 14 can keep the label paper taut when moving and retracting, so that the label paper separates from the backing paper more smoothly. This realizes the centering and clamping of the emulsion explosive to prevent the explosive from shifting, and facilitates the automatic sequential labeling of the emulsion explosive.
[0028] A limiting roller 8 is provided on the side wall of the support plate 3 on one side of the placement roller 16, and the limiting roller 8 is movably connected to the support plate 3. A driving roller 9 is provided on the side wall of the support plate 3 on one side of the limiting roller 8, and the driving roller 9 is movably connected to the support plate 3.
[0029] Squeeze rollers 14 are movably installed on the side walls of the support plates 3 on both sides of the drive roller 9. A stepper motor 15 is provided on the side wall of the support plate 3 on one side of the drive roller 9. The stepper motor 15 plays the role of power drive. A placement plate 2 is provided on the side wall of the support plate 3 on one side of the stepper motor 15.
[0030] A drive shaft 5 is installed at the output end of the stepper motor 15. A first pulley assembly 6 is provided on the surface of the drive shaft 5 and is connected to the drive roller 9. A second pulley assembly 7 is provided on the surface of the drive roller 9 and is connected to the limit roller 8.
[0031] When the label is attached to the emulsion explosive, because the emulsion explosive is cylindrical, the label cannot completely adhere to the explosive. At this time, the cylinder 10 is opened, which drives the first push arm 11 to move. The first push arm 11 drives the lower pressure frame 12 and the lower pressure roller 13 to move, so that the lower pressure roller 13 contacts the label. The friction between the explosive and the belt conveyor 1 is greater than the friction between the lower pressure roller 13 and the label. The belt conveyor 1 can drive the explosive to continue moving, and the explosive drives the lower pressure roller 13 to rotate. The lower pressure roller 13 rolls and presses the label, making the label adhere more tightly to the explosive. This completes the labeling operation of the emulsion explosive, facilitates the rolling and pressing of the label to prevent it from falling off, and improves the adhesion between the label and the explosive.
[0032] Work steps
[0033] Cylindrical emulsion explosives are sequentially conveyed by belt conveyor 1 to the space between two sets of clamping blocks 17. An electric push rod 18 drives a second push arm 19, which in turn moves the two sets of clamping blocks 17 closer together, clamping and fixing the emulsion explosives. A stepper motor 15 drives a drive shaft 5 to rotate, which in turn drives a drive roller 9 via a first pulley assembly 6. The drive roller 9, in turn, drives a limiting roller 8 via a second pulley assembly 7. The drive roller 9 moves the label paper, which moves across the surfaces of the limiting roller 8, the placement roller 16, and the placement plate 2. Because one end of the placement plate 2 has a blade-like design, the edge of the label paper will curl up as it moves across it. As the base paper moves, the label paper gradually detaches from the base paper and adheres to the emulsion explosive. At this point, the electric push rod 18 is turned off, and the belt conveyor 1 moves the emulsion explosives. During the movement of the emulsion explosives, the label paper... The label is automatically applied to the surface of the emulsion explosive by repeating the above operation. The limiting cooperation between the drive roller 9 and the pressure roller 14 keeps the label paper taut during movement and retraction, making it easier for the label paper to separate from the backing paper. When the label paper is applied to the emulsion explosive, because the emulsion explosive is cylindrical, the label cannot be completely adhered to the explosive. The cylinder 10 drives the first push arm 11 to move, which in turn drives the lower pressure frame 12 and the lower pressure roller 13 to move, so that the lower pressure roller 13 contacts the label. The friction between the explosive and the belt conveyor 1 is greater than the friction between the lower pressure roller 13 and the label paper. The belt conveyor 1 can continue to move the explosive, which drives the lower pressure roller 13 to rotate. The lower pressure roller 13 rolls and presses the label paper, making the label paper adhere more tightly to the explosive, thus completing the labeling operation of the emulsion explosive.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
