Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, specifically to a rotary fixed-point positioning labeling machine. Background Technology

[0002] A labeling machine is a device that uses adhesive to attach paper or metal foil labels to a specified packaging container. Some labeling machines can attach single labels to the circumference of cylindrical or conical products, achieving circumferential or semi-circular labeling.

[0003] Chinese utility model patent with announcement number "CN211685992U" discloses a rotary round bottle labeling machine, including a cabinet body. The cabinet body houses an electrical control unit. The cabinet body also includes a rejection mechanism, a pressure head mechanism, a bottle inlet conveyor line, a bottle outlet conveyor line, a rotary mechanism, and a labeling mechanism. The labeling mechanism includes a third cylinder, a nylon pressure head, a rubber roller, a second motor, a gantry frame, and a cross-shaped adjusting slider. The second motor is installed at the bottom of the gantry frame, the third cylinder is located at the top of the gantry frame, the nylon pressure head is fixed at the bottom of the third cylinder, the rubber roller is fixed at the top of the gantry frame away from the third cylinder, and the cross-shaped adjusting slider is located on one side of the gantry frame. The labeling mechanism is also equipped with an electronic eye.

[0004] However, as can be seen from paragraph

[0035] of the instruction manual, the labeling mechanism of the aforementioned rotary bottle labeling machine requires the rubber roller to contact the outer circumference of the cylindrical bottle and rotate in order to drive the bottle body to rotate. In actual production, the rubber roller is prone to idle rotation, that is, it cannot make stable contact with the bottle body to drive the bottle body to rotate. The label cannot be evenly attached to the outer surface of the round bottle, resulting in a high rate of labeling defects.

[0005] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a rotary positioning labeling machine that provides stable rotation and secure labeling, in order to solve the above-mentioned problems existing in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rotary fixed-point positioning labeling machine, including a frame, the frame being provided with a feeding mechanism, a labeling mechanism, a spinning mechanism, and a discharging mechanism. The feeding mechanism is used to transport materials to the spinning mechanism, and the discharging mechanism is used to output the materials after labeling. The spinning mechanism is characterized in that: the spinning mechanism includes a first spinning frame and a second spinning frame. The first spinning frame is provided with a spinning mounting seat and a sliding component for driving the spinning mounting seat to move. The spinning mounting seat is provided with a spinning component above the second spinning frame, and a spinning platform for carrying materials is provided above the second spinning frame. The spinning component can abut against the materials to cause the materials to rotate on the spinning platform, and the labeling mechanism can label the rotating materials.

[0008] By adopting the above technical solution: the swivel mechanism is located at the junction of the feeding mechanism and the discharging mechanism. The material is transferred from the feeding mechanism to the swivel platform of the swivel mechanism. Then, the sliding component pushes the swivel mounting seat to move to one side of the swivel platform, so that the swivel component comes into contact with the material and drives the material to rotate. At the same time, the labeling mechanism applies the label to the outer circumference of the material while the material is rotating, completing one circumferential labeling of the material. After labeling is completed, the discharging mechanism transfers and outputs the material. Compared with the existing method of using rubber rollers, the swivel component is located above the material, and the sliding component can drive the swivel component to move along the axial direction of the first swivel frame. The swivel component can stably contact the material and drive the material to rotate. It can perform fixed-point positioning labeling on products with raised cylindrical parts, improving the stability and effectiveness of the material labeling rotation.

[0009] The aforementioned rotary positioning labeling machine can be further configured as follows: the material-spinning assembly includes a servo motor mounted on a material-spinning mounting base and a material-spinning pressure head for rotating the material. The output end of the servo motor is provided with a coupling, and the material-spinning pressure head is linked to the output end of the servo motor through the coupling. The material-spinning pressure head is fitted with a first material-spinning bushing, and the material-spinning pressure head and the first material-spinning bushing are rotatably engaged. The sliding assembly includes a pull rod cylinder mounted above the first material-spinning frame and a sliding bushing that is slidably engaged with the first material-spinning frame. The material-spinning mounting base is linked to the output end of the pull rod cylinder. The operation of the pull rod cylinder drives the material-spinning mounting base to move vertically along the first material-spinning frame, causing the material-spinning pressure head to contact or separate from the material.

[0010] By adopting the above technical solution: the pull rod cylinder pushes the swivel mounting plate to move up and down along the first swivel frame, so that the swivel pressure head contacts or separates from the material. When the swivel pressure head is in contact with the material, it positions the material on the swivel platform to prevent the material from shaking or shifting. Then, the servo motor drives the swivel pressure head to rotate through the coupling, thereby causing the material to rotate circumferentially. The first swivel bushing can radially limit the swivel pressure head, improving the stability of the circumferential rotation of the swivel pressure head. At the same time, the labeling mechanism labels the material. After the labeling is completed, the pull rod cylinder resets and drives the swivel mounting plate to reset, thereby causing the swivel pressure head to detach from the material. Then, the discharge mechanism outputs the labeled material, completing the labeling process.

[0011] The aforementioned rotary fixed-point labeling machine can be further configured as follows: the first rotating frame is also provided with a fixed support, the fixed support is provided with a top material cylinder, the output end of the top material cylinder is provided with a top material seat, the top material seat is provided with a top material shaft on the side opposite to the top material cylinder, the top material shaft is sleeved with a top material roller, the operation of the top material cylinder drives the top material seat to move, causing the top material roller to contact or separate from the outer surface of the material.

[0012] By adopting the above technical solution: the top material cylinder pushes the top material seat to a predetermined position. When the material enters the swirl mechanism, the roller can position the material by contact, making the contact between the swirl head and the material more precise. At the same time, when the material is labeled, the label on the outer surface of the material can be smoothed, making the adhesion between the label and the material more stable.

[0013] The aforementioned rotary fixed-point positioning labeling machine can be further configured as follows: the rotating platform is provided with a rotating disc, a rotating shaft is provided below the rotating disc, the second rotating frame is provided with a second rotating shaft sleeve, one end of the rotating shaft is fixedly connected to the rotating disc, and the other end is rotatably engaged with the second rotating shaft sleeve, the rotating shaft is provided with a positioning convex ring, and the positioning convex ring can abut against the end face of the second rotating shaft sleeve.

[0014] By adopting the above technical solution: when the material enters the swivel mechanism, it will be placed on the swivel disc. When the swivel pressure head drives the material to rotate, it will drive the swivel disc to rotate synchronously around the swivel shaft, avoiding wear caused by friction between the material port and the swivel platform. At the same time, the positioning convex ring of the swivel shaft abuts against the second swivel shaft sleeve, which limits the axial movement of the swivel shaft and prevents the swivel shaft from moving axially, thus improving the stability of the swivel disc rotation.

[0015] The aforementioned rotary fixed-point positioning labeling machine can be further configured as follows: the feeding mechanism and the discharging mechanism are arranged parallel to each other on the frame; one end of the swivel mechanism is linked to the feeding mechanism and the other end is linked to the discharging mechanism; the feeding mechanism is provided with a first pushing cylinder and a second pushing cylinder near the swivel mechanism; the body of the first pushing cylinder is fixedly connected to the feeding mechanism and the output end is provided with a first pushing plate; the first pushing plate has a first pushing notch; the operation of the first pushing cylinder causes the first pushing plate to push the material from the feeding mechanism into the swivel mechanism; the body of the second pushing cylinder is fixedly connected to the feeding mechanism and the output end is provided with a second pushing plate; the second pushing plate has a second pushing notch; the operation of the second pushing cylinder causes the second pushing plate to push the labeled material from the swivel mechanism into the discharging mechanism.

[0016] By adopting the above technical solution: when the material is conveyed along the feeding mechanism to the end near the swirl mechanism, the first pushing cylinder drives the first pushing plate to move. The first pushing plate pushes the material waiting to be transferred at the end of the feeding mechanism. During the pushing process, the material adheres to the side wall of the first pushing notch, keeping the material moving in the same direction to the bottom of the swirl assembly, thus maintaining the stability of the material transfer from the feeding mechanism to the swirl mechanism. In addition, the second discharging cylinder is coaxially arranged with the discharging mechanism. After the material is labeled, the second pushing cylinder drives the second pushing plate to move, so that the second pushing notch contacts the outer peripheral surface of the material, pushing the material out of the swirl mechanism and transferring it to the discharging mechanism, completing the automatic transfer of the material.

[0017] The aforementioned rotary fixed-point positioning labeling machine can be further configured as follows: the labeling mechanism includes a labeling component for labeling, a first adjusting component for adjusting the labeling angle, a second adjusting component for adjusting the labeling lateral position, and a third adjusting component for adjusting the labeling height. The second adjusting component is linked with the first adjusting component, the third adjusting component is linked with the second adjusting component, and the labeling component is linked with the third adjusting component.

[0018] By adopting the above technical solution: the first adjustment component, the second adjustment component, and the third adjustment component realize multi-directional adjustment of the labeling component, enabling the labeling component to be applicable to materials of different shapes and improving the applicability of the labeling machine.

[0019] The aforementioned rotary fixed-point positioning labeling machine can be further configured as follows: the labeling component includes a mounting plate, the mounting plate is provided with a label unwinding reel for unwinding the label tape, a label winding reel for winding the tape, several guide rollers, a traction roller group, and a label peeling plate for peeling off the label, and a label feeding cylinder is provided on the side of the mounting plate near the label peeling plate, the body of the label feeding cylinder is fixedly connected to the mounting plate, and the output end is provided with a label feeding plate.

[0020] By adopting the above technical solution: the label tape is placed on the label tape reel, and the label tape is transmitted to the label peeling plate through multiple guide rollers. After the label is peeled off, it is transmitted to the label take-up reel through the traction roller group. The label take-up reel rotates continuously to continuously wind up the label tape, realizing automatic label tape discharge and winding. When labeling materials, the label peeling plate peels off the label part, and then the label feeding cylinder pushes the label feeding plate to move, causing the label tape to move towards the material side, so that the label end is attached to the outer peripheral surface of the material, realizing the auxiliary label feeding function. Subsequently, as the material rotates, the label is gradually peeled off from the label tape and attached to the outer peripheral surface of the material, improving the efficiency and stability of label peeling and bonding.

[0021] The aforementioned rotary positioning labeling machine can be further configured as follows: the first adjustment component includes a first adjustment seat, a first flipping frame, and a first sliding plate mounted on the frame. One end of the first flipping frame is hinged to the first adjustment seat, and the other end is hinged to an adjustment cylinder. The first sliding plate is slidably engaged with the first flipping frame. A first screw passes through the first flipping frame and is threadedly connected to the first sliding plate. A first adjustment handwheel is provided at the end of the first screw away from the first adjustment seat. A second screw, threadedly connected to the adjustment cylinder, passes through the adjustment cylinder. A fixed seat is hinged to the end of the second screw opposite to the adjustment cylinder, and the fixed seat is fixedly connected to the frame.

[0022] By adopting the above technical solution: rotating the first adjusting handwheel causes the first sliding plate to move relative to the first flipping frame, thereby adjusting the distance between the labeling mechanism and the spinning mechanism; and by rotating the adjusting cylinder, the first flipping frame is rotated upward or downward relative to the hinge point connected to the first adjusting seat, thereby changing the angle of the labeling component relative to the transmission mechanism, labeling the inclined surface of the item, and making the first adjusting component integrate angle adjustment and position adjustment.

[0023] The aforementioned rotary positioning labeling machine can be further configured as follows: the second adjustment component includes a second adjustment seat disposed on a first sliding plate, the second adjustment seat is provided with a second flip frame, the end of the second flip frame is hinged to the second adjustment seat, a third screw is rotatably engaged in the middle of the second flip frame, the third screw is threadedly connected to the second sliding plate, a third adjustment handwheel is provided at the end of the third screw, a first flip block is provided at the end of the second flip frame that is hinged to the second adjustment seat, a second flip block is hinged to the end of the second adjustment seat near the first flip block, a fourth screw is threadedly connected to the first flip block, one end of the fourth screw is rotatably engaged with the second flip block, and the other end is provided with a fourth adjustment handwheel.

[0024] By adopting the above technical solution: rotating the third adjusting handwheel can drive the third screw to rotate, thereby driving the second sliding plate to move axially along the third screw, thereby adjusting the lateral position of the labeling component. Rotating the fourth adjusting handwheel can drive the fourth screw to rotate, thereby causing the second flipping block to move axially along the fourth screw, thereby causing the second flipping frame to rotate upward or downward around the hinge point with the first sliding plate, thus cooperating with the first adjusting component to realize bidirectional angle adjustment of the labeling component.

[0025] The aforementioned rotary positioning labeling machine can be further configured as follows: the third adjustment component includes a third adjustment seat, several adjustment slide rods disposed on the third adjustment seat, and a fifth screw that rotates with the third adjustment seat. The fifth screw has a fifth adjustment handwheel at the end away from the second sliding plate, and the fifth screw is threadedly connected to the sliding seat. The mounting plate is linked with the sliding seat.

[0026] By adopting the above technical solution, rotating the fifth adjusting handwheel can drive the fifth screw to rotate, causing the sliding seat to move along the axis of the fifth screw, which in turn drives the mounting plate to move up and down, thereby adjusting the height of the labeling component. The structure is simple and the operation is convenient.

[0027] The beneficial effects of this utility model are as follows: the material is fed from the feeding mechanism and transferred to the swivel mechanism. The swivel mechanism abuts against the upper surface of the material through the swivel pressure head. The servo motor can drive the material to rotate circumferentially at a uniform speed through the swivel pressure head. With the help of the labeling mechanism, the label can be stably attached to the outer circumferential surface of the material. Compared with the existing technology of contacting the outer circumferential surface of the material with the roller and driving the material to rotate, the contact between the swivel pressure head and the material is more stable. At the same time, the swivel plate set on the swivel platform can rotate synchronously when the material rotates, preventing wear on the material end. It realizes the fixed-point positioning and labeling of products with protruding cylindrical parts. In addition, by setting the top roller, the material can be positioned and the label attached to the outer circumferential surface of the material can be smoothed, improving the stability of the label.

The mounting plate 311 is linked with the sliding seat 345.

[0039] like Figure 8 As shown, the material spinning mechanism 4 includes a first material spinning frame 41 and a second material spinning frame 42. The first material spinning frame 41 is provided with a material spinning mounting seat 411 and a sliding component 43 for driving the material spinning mounting seat 411 to move. The material spinning mounting seat 411 is provided with a material spinning component 44 above the second material spinning frame 42. The second material spinning frame 42 is provided with a material spinning platform 45 for carrying materials. The material spinning component 44 can abut against the materials to cause the materials to rotate on the material spinning platform 45. The labeling mechanism 3 can label the rotating materials.

[0040] The sliding assembly 43 includes a pull rod cylinder 431 located above the first spinning frame 41 and a sliding bushing 432 that slides with the first spinning frame 41. The spinning mounting seat 411 is linked to the output end of the pull rod cylinder 431. The operation of the pull rod cylinder 431 drives the spinning mounting seat 411 to move vertically along the first spinning frame 41, causing the spinning pressure head 442 to contact or separate from the material.

[0041] like Figure 9 As shown, the material swirl assembly 44 includes a servo motor 441 mounted on a material swirl mounting base 411 and a material swirl head 442 for rotating the material. The output end of the servo motor 441 is provided with a coupling 443. The material swirl head 442 is linked to the output end of the servo motor 441 through the coupling 443. The material swirl head 442 is fitted with a first material swirl bushing 444. The material swirl head 442 and the first material swirl bushing 444 are rotatably engaged. The first material swirl bushing 444 is provided with a bearing.

[0042] like Figure 10 As shown, the spinning platform 45 is provided with a spinning disk 451, and a spinning shaft 452 is provided below the spinning disk 451.

The spinning shaft 452 is provided with a positioning convex ring 454, which can abut against the end face of the second spinning shaft sleeve 453.

[0043] The working principle of this embodiment is as follows: when the material on the feeding mechanism 2 is transferred to the tail of the feeding mechanism 2, the first pushing cylinder 21 operates to push the first pushing plate 211, so that the first pushing notch 212 contacts the outer peripheral surface of the material and pushes the material to move towards the swivel platform 45. At the same time, the top cylinder 461 pushes the top seat 462 to move to the predetermined position, and the top roller 464 of the top shaft 463 makes positioning contact with the material that has moved to the swivel plate 451. Then the first pushing cylinder 21 is reset.

[0044] Then, the pull rod cylinder 431 operates, driving the swivel mounting base 411 to move downward along the first swivel frame 41. The swivel pressure head 442 presses against the upper surface of the material, and the material is positioned on the swivel disc 451. Subsequently, the servo motor 441 operates, driving the swivel pressure head 442 to rotate. The material and the swivel disc 451 rotate synchronously around the central axis of the swivel shaft 452. While the material is rotating, the label peeling plate 316 peels off the label, and the label feeding cylinder 317 pushes the label feeding plate 318 to push the label strip to one side of the material. The peeled label end is attached to the outer peripheral surface of the material. Then, the material continues to rotate, and the label is peeled off from the label strip and attached to the outer peripheral surface of the material as the material rotates. While the label is attached to the outer peripheral surface of the material, the top roller 464 contacts the outer peripheral surface of the material and smooths the label.

[0045] After labeling is completed, the second pusher cylinder 22 pushes the second pusher plate 221 to move, and the second pusher notch 222 contacts the outer peripheral surface of the material, pushing the labeled material to the discharge mechanism 5 to complete the labeling operation.

[0046] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
