Description
A conveniently adjustable labeling and coding machine Technical Field
[0001] This utility model relates to the technical field of labeling and coding integrated machines, and in particular to a labeling and coding integrated machine that is easy to adjust. Background Technology
[0002] In the field of integrated labeling and coding machine technology, for automated labeling operations on round bottles, the stability of label separation from the backing paper, the accuracy of adhesion, and the ease of equipment height adjustment are key issues affecting production efficiency and labeling quality.
[0003] In existing technologies, traditional labeling equipment typically uses mechanical peeling to separate the label layer from the backing paper layer when processing label rolls. However, for labels of different materials (such as paper and PET) or different viscosities, problems such as incomplete separation and label stretching and deformation can easily occur, leading to label misalignment or wrinkles. Furthermore, when labeling round bottles of different heights (such as small-capacity sample bottles and large-capacity regular bottles), traditional equipment relies on manual screws or detachable brackets for label height adjustment. The adjustment process is cumbersome and lacks precision, making it difficult to meet the rapid changeover requirements of multi-variety, small-batch production. Therefore, we propose a conveniently adjustable integrated labeling and coding machine. Summary of the Invention
[0004] The main purpose of this utility model is to provide a labeling and coding machine that is easy to adjust, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A conveniently adjustable labeling and coding machine includes a roll support and a transmission belt for conveying round bottles. The roll support is rotatably mounted with an unwinding roller, a tension adjusting roller group, a take-up roller, and a label roll. A steering roller is rotatably mounted on the side of the roll support near the transmission belt. The bottom paper layer of the label roll is wound in a U-shape around the steering roller.
[0007] A coarse roller is rotatably mounted on the other side of the steering roller. A servo motor is fixedly mounted above the roll support. The output end of the rotor in the servo motor is connected to the coarse roller. The outer wall of the coarse roller adsorbs the label layer of the label roll through negative pressure, so that the label layer is separated from the backing paper layer and turned to the side of the transmission belt.
[0008] On the other side of the transmission belt, there are two pressure rollers parallel to the coarse roller. The top of the two pressure rollers is connected to a movable frame. A double-rod cylinder is provided on one side of the movable frame. The two pressure rollers are connected to the output end of the double-rod cylinder through the movable frame. The double-rod cylinder pushes the pressure rollers to squeeze the round bottle against the outer wall of the coarse roller, so that the label layer is adhered to the outer periphery of the round bottle with glue.
[0009] Preferably, a label height adjustment platform is provided below the roll support. The label height adjustment platform includes a fixed plate, a lifting plate, and two sets of diamond-shaped lifting frames. The lifting plate is fixed to the roll support, and the fixed plate is connected to the transmission belt support. The diamond-shaped lifting frames are divided into two symmetrical groups by eight X-shaped intersecting hinges. Each group is hinged vertically by two X-shaped hinges. The hinges of the two groups of hinges are rotatably connected by a connecting rod. A guide rod is provided parallel between the fixed plate and the lifting plate. The top and bottom ends of the hinges are slidably connected to the guide rod by the connecting rod. Two vertical rods are vertically connected above the fixed plate.
[0010] Preferably, the coarse roller includes a central roller and an outer cylinder, a negative pressure cavity is provided between the central roller and the outer cylinder, a small hole communicating with the negative pressure cavity is provided on the outer wall of the outer cylinder, a first end face bearing and a second end face bearing are respectively connected to the lower part of the central roller and the outer cylinder, a dust collection cylinder is detachably connected to the lower part of the first end face bearing and the second end face bearing, a dust collection chamber is provided inside the dust collection cylinder, and a connection port is connected to one side of the top of the dust collection chamber.
[0011] Preferably, a dual-head motor is installed above the two vertical rods. Both ends of the rotor of the dual-head motor are fixedly installed with adjusting screws. The two adjusting screws are threadedly connected to the two connecting rods in the middle. The dual-head motor drives the diamond lifting frame to extend and retract through the adjusting screws to adjust the height of the coil support.
[0012] Preferably, the outlet of the connection port is fixedly connected to a connecting pipe, and the end of the connecting pipe is connected to a vacuum pump, which is fixedly installed on the roll support.
[0013] Preferably, the two pressure rollers and the coarse roller are arranged in a triangle, and the double-rod cylinder drives the movable frame to move the pressure rollers horizontally.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This easily adjustable labeling and coding machine uses the U-shaped winding design of the steering roller to achieve initial separation of the label layer from the backing paper layer during the label separation process. Combined with the negative pressure adsorption structure on the outer wall of the coarse roller, the negative pressure cavity between the central roller and the outer cylinder and the small holes on the outer wall form a stable adsorption force, ensuring that labels of different materials are completely separated from the backing paper layer. This avoids the problems of incomplete separation or label stretching and deformation caused by traditional mechanical peeling, thus improving the reliability of separation.
[0016] 2. This easily adjustable labeling and coding machine features two triangularly distributed pressure rollers that work in conjunction with a coarse roller. A dual-cylinder-driven movable frame dynamically adjusts the contact pressure between the pressure rollers and the round bottle. This allows for the application of appropriate pressure based on the bottle's diameter and curvature, precisely pressing the bottle against the outer wall of the coarse roller. This ensures that the adhesive on the inner side of the label layer adheres evenly to the bottle body, effectively eliminating edge lifting and central air bubbles, and significantly improving the accuracy of label placement and surface flatness.
[0017] 3. This easily adjustable labeling and coding machine addresses the labeling needs of round bottles of varying heights. The label height adjustment platform at the bottom of the machine features an innovative diamond-shaped lifting frame structure. This structure consists of symmetrically distributed X-shaped hinges and connecting rods. A dual-head motor drives an adjusting screw to synchronously control the extension and retraction of the diamond frame, causing the roll support to move vertically along the guide rod. This enables rapid electric adjustment of the label application height, allowing for quick adaptation to various specifications from small-capacity sample bottles to large-capacity regular bottles without manual calibration. This significantly reduces changeover time and meets the efficient changeover requirements of multi-variety, small-batch production.
[0018] 4. This easily adjustable labeling and coding machine features a detachable dust collection cylinder below the coarse roller for negative pressure system maintenance. Impurities such as paper scraps and adhesive particles generated during the separation process are sucked into the negative pressure chamber through small holes and then settle into the dust collection chamber, preventing the adsorption holes from becoming clogged, ensuring long-term stable negative pressure adsorption force, reducing the frequency of equipment downtime for maintenance, and improving overall operational reliability.

Detailed Implementation
[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] As shown in Figures 1-4, a conveniently adjustable labeling and coding integrated machine includes a label roll 6, a roll support 1 for mounting the label roll 6, and a transmission belt 2 for conveying round bottles. The roll support 1 is rotatably mounted with an unwinding roller 3, a tension adjusting roller group 4, and a take-up roller 5. The bottom paper layer of the label roll 6 is wound around the unwinding roller 3 and tensioned by the tension adjusting roller group 4. The waste bottom paper is finally wound onto the take-up roller 5. The label layer of the label roll 6 is equidistantly segmented and adhered to the bottom paper layer, and is conveyed to the labeling area along with the bottom paper.
[0026] Referring to Figure 1, a guide roller 7 is rotatably installed on the side of the roll support 1 near the transmission belt 2. The bottom paper layer of the label roll 6 is wrapped around the guide roller 7 in a U-shape. The curvature of the guide roller 7 is used to initially separate the bottom paper layer of the label roll 6 from the label layer.
[0027] Referring to Figure 1, a coarse roller 8 is provided on the other side of the steering roller 7. Its axis is parallel to the steering roller 7 and is driven to rotate by a servo motor 15. The outer wall of the coarse roller 8 adsorbs the label layer of the label roll 6 by negative pressure, so that the label layer is completely separated from the backing paper layer. As the coarse roller 8 rotates, the adsorption force on one side of the steering belt 2 is provided by a vacuum pump 13.
[0028] Referring to Figures 3 and 4, the coarse roller 8 is composed of a central roller 801 and an outer cylinder 802. The outer cylinder 802 is coaxially fixed around the central roller 801. An annular negative pressure cavity 803 is formed between the central roller 801 and the outer cylinder 802. Small holes 804 are evenly distributed on the outer wall of the outer cylinder 802 and are connected to the negative pressure cavity 803.
[0029] Referring to Figure 4, the lower ends of the center roller 801 and the outer cylinder 802 are detachably connected to the dust collection cylinder 807 via the first end face bearing 805 and the second end face bearing 806, respectively, which facilitates the cleaning of impurities. The dust collection chamber 808 inside the dust collection cylinder 807 is connected to the connecting pipe 12 of the vacuum pump 13 via the connecting port 809 at the top.
[0030] In this embodiment, after the vacuum pump 13 is started, negative pressure is applied to the negative pressure chamber 803 through the connecting pipe 12. Under the action of pressure difference, the label layer is adsorbed onto the outer wall of the outer cylinder 802, achieving stable separation from the bottom paper layer.
[0031] Impurities such as paper scraps and adhesive particles generated during the separation process are drawn into the negative pressure chamber 803 through the small hole 804 and settle into the dust collection chamber 808 to avoid clogging the small hole 804;
[0032] Two pressure rollers 9 parallel to the coarse roller 8 are provided on the other side of the transmission belt 2. The three are arranged in a triangle. The pressure rollers 9 are connected to the output end of the double rod cylinder 11 through the movable frame 14. The double rod cylinder 11 is fixed on the support of the transmission belt 2.
[0033] When the round bottle moves with the transmission belt 2 between the pressure roller 9 and the coarse roller 8, the double-rod cylinder 11 pushes the movable frame 14 to move horizontally, so that the two pressure rollers 9 squeeze the round bottle against the outer wall of the coarse roller 8. At this time, the glue on the inner side of the label layer comes into contact with the surface of the round bottle and adheres tightly under the adjustable pressure of the pressure roller 9.
[0034] Referring to Figure 2, a label height adjustment platform 10 is set below the roll support 1. The label height adjustment platform 10 includes a horizontally parallel fixed plate 1001 and a lifting plate 1002. The fixed plate 1001 is fixedly connected to the support of the transmission belt 2, and the lifting plate 1002 is connected to the fixed plate 1001 through two sets of diamond-shaped lifting frames.
[0035] Referring to Figure 2, each set of diamond-shaped lifting frames consists of eight X-shaped intersecting hinge rods 1003, divided into two symmetrical groups. Each group is hinged vertically by two X-shaped hinge rods 1003, forming four sets of intersecting hinge nodes. The hinge points of the two sets of hinge rods 1003 are rotatably connected by connecting rods 1004, forming a parallelogram linkage structure to ensure synchronous extension and retraction.
[0036] Referring to Figure 2, two guide rods 1005 are arranged parallel to each other between the fixed plate 1001 and the lifting plate 1002. The top and bottom ends of the hinge rod 1003 are slidably connected to the guide rod 1005 through linear bearings on the connecting rod 1004. Two vertical rods 1006 are arranged vertically above the fixed plate 1001. The top ends of the two vertical rods 1006 are equipped with a double-head motor 1007 by sliding blocks. The rotor ends of the double-head motor 1007 are fixed with adjusting screws 1008. The adjusting screws 1008 are threadedly connected to the connecting rod 1004 in the middle of the diamond-shaped lifting frame.
[0037] It should be noted that when the dual-head motor 1007 rotates forward, the two adjusting screws 1008 synchronously drive the diamond-shaped lifting frame to unfold, and the lifting plate 1002 rises vertically along the guide rod 1005 to raise the height of the roll support 1. When it rotates in reverse, it retracts and descends to meet the labeling requirements of round bottles of different heights.
[0038] The present invention relates to the collaborative workflow of this easily adjustable labeling and coding integrated machine:
[0039] First, label conveying and separation: the unwinding roller 3 releases the label roll 6, and after the bottom paper layer is tensioned by the tension adjusting roller group 4, it bends in a U-shape around the steering roller 7. Under the negative pressure adsorption of the coarse roller 8, the label layer separates from the bottom paper and rotates with the coarse roller 8 to one side of the transmission belt 2.
[0040] Second, round bottle bonding and height adjustment: The transmission belt 2 conveys the round bottle to the space between the pressure roller 9 and the coarse roller 8. The double-rod cylinder 11 pushes the pressure roller 9 to squeeze the round bottle so that the label layer is bonded to the bottle body. When the height of the round bottle needs to be changed, the double-head motor 1007 is started, and the height of the roll support 1 is adjusted by the adjusting screw 1008 to drive the diamond lifting frame to ensure that the label bonding position is accurate.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
