Description

Technical Field

[0001] This utility model relates to the field of tube bonding machine technology, specifically a single-path tube bonding machine. Background Technology

[0002] In industries such as daily chemicals and pharmaceuticals, labeling the surface of tubular metal containers (such as aerosol cans) is a crucial step in the production process. Traditional labeling equipment often uses conveyor belts in conjunction with roller coating mechanisms to apply labels. However, due to the unique characteristics of tubular metal containers, the smooth surface of the cans makes them prone to slippage due to inertia during high-speed rotation, leading to label misalignment or wrinkling. In particular, some aerosol cans are deformed, causing uneven magnetic resistance between the chuck magnetic seat in the chuck assembly and the can body, which can cause the can to rotate, resulting in inaccurate positioning and presenting certain defects. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a single-path labeling machine, comprising a frame assembly, on which a chuck assembly for clamping and rotating tubular containers is mounted, a positioning component is provided at the inlet end of the chuck assembly, the positioning component is connected to the frame assembly via a guide rail mechanism, and its positioning end is coaxially aligned with the clamping position of the chuck assembly for axial positioning of the tubular containers, and a label outlet assembly is provided at the outlet end of the chuck assembly, the label outlet assembly adopts a push rod structure, and its ejection trajectory is perpendicularly connected to the conveying direction of the conveyor belt assembly for ejection to complete label application.

[0004] A labeling component is fixed on the frame assembly. The labeling component is suspended above the chuck assembly's workstation and is used to apply labels to the container surface. The labeling component includes a label peeling mechanism and a label pressing mechanism, and its label outlet is directly opposite the center of the chuck assembly's clamping workstation.

[0005] The test tube assembly is fixed on the frame assembly. The test tube assembly is located near the inlet of the chuck assembly and is used to detect the container's position.

[0006] A chuck positioning photoelectric sensor assembly is fixed on the frame assembly. The chuck positioning photoelectric sensor assembly is connected to the rotating shaft of the chuck assembly and is used to detect the rotation angle. The probe assembly and the chuck positioning photoelectric sensor assembly are connected to the control system. The probe assembly triggers the chuck clamping action, and the chuck positioning photoelectric sensor assembly controls the labeling start position.

[0007] A conveyor belt assembly is fixed on the frame assembly, which is used to receive the containers output by the outlet assembly.

[0008] The conveyor belt assembly is symmetrically equipped with guardrail assemblies on both sides. The spacing of the guardrail assemblies is adjustable so that the inner spacing matches the diameter of the tubular container, thereby constraining the movement trajectory of the container.

[0009] A bottle-separating assembly is installed at the end of the conveyor belt assembly. The bottle-separating assembly uses adjustable-pitch dials to control the container output interval and separate the output containers.

[0010] As a further improvement to the above solution, a human-machine component is provided on one side of the rack assembly. The human-machine component is a container for setting and outputting equipment parameters.

[0011] Through the above technical solution, the human-machine component integrates a touch screen and control buttons, and is electrically connected to the chuck component, labeling component, and conveyor belt component through a PLC.

[0012] As a further improvement to the above solution, the chuck assembly includes an upper chuck, a lower chuck, and a roller assembly, with multiple roller assemblies disposed between the upper and lower chucks.

[0013] Multiple chuck magnetic seats are distributed on the upper and lower chucks.

[0014] With the above technical solution, the upper chuck and the lower chuck are arranged in parallel relative to each other, and multiple roller assemblies are distributed axially between the upper chuck and the lower chuck. The roller assemblies undertake the core power transmission and precise positioning of the tubular container. At the same time, the chuck magnetic seat integrates a magnetic transmission structure, and achieves non-contact power transmission and precise control through magnetic field coupling.

[0015] As a further improvement to the above solution, the roller assembly includes two rollers, each roller having a connecting groove at both ends, and an annular groove at the interface of the connecting groove.

[0016] A connecting rod mechanism and a deep groove ball bearing are movably connected within the connecting groove, with the connecting rod mechanism movably connected within the deep groove ball bearing.

[0017] A magnetic ring is movably connected inside the annular groove, and an installation hole is provided inside the magnetic ring.

[0018] Through the above technical solution, each set of rotating roller assemblies clamps and conveys the tubular container through two rotating rollers. The deep groove ball bearing converts the rotational friction of the rotating rollers into rolling friction, reducing power loss. At the same time, it constrains the radial displacement of the linkage mechanism, ensuring stable rotation of the rotating rollers. Furthermore, the magnetic rings installed in the annular grooves at both ends of the rotating rollers utilize the magnetic resistance effect to increase the resistance of the two rotating rollers to the aerosol can, preventing the can from rotating again after positioning and improving positioning accuracy.

[0019] As a further improvement to the above solution, the linkage mechanism includes a base fixed in the connecting groove, a rotary knob rotatably connected to the base, and a connecting rod movably connected to the rotary knob.

[0020] The upper and lower chucks have corresponding connecting holes, and the connecting rod is movably sleeved in the mounting hole and the connecting hole, and fixed in the inner ring of the deep groove ball bearing.

[0021] Through the above technical solution, when the connecting rod rotates, it drives the inner ring of the deep groove ball bearing to rotate, reducing the frictional resistance of the connecting rod. At the same time, the mounting hole and connecting hole ensure the stability of the connecting rod rotation during rotation.

[0022] As a further improvement to the above solution, a tension spring is movably connected between the connecting rod and the rotating knob.

[0023] With the above technical solution, the tension spring is used to push the connecting rod so that the front end of the connecting rod is inserted into the corresponding connecting hole. When disassembling and assembling the rotating roller, the connecting rod is pressed to disengage its front end from the connecting hole, thereby removing the corresponding rotating roller from between the upper chuck and the lower chuck.

[0024] As a further improvement to the above solution, a stabilizing groove is provided on the rotary knob, and a stabilizing knob is fixed at the bottom of the connecting rod, with the stabilizing knob movably fitted into the stabilizing groove.

[0025] Through the above technical solution, when the connecting rod is pressed, the bottom stabilizing button moves up and down in the stabilizing groove, thereby ensuring the stability of the connecting rod when it is disengaged from and installed by the upper and lower chucks.

[0026] As a further improvement to the above solution, a protruding button is provided in the annular groove, and a groove is provided on the side of the magnetic ring, which is engaged with the side of the protruding button.

[0027] Through the above technical solution, the magnetic ring adopts a ring-shaped strong magnet. When the magnetic ring is installed in the annular groove, it is engaged with the side of the convex button through the groove on the side, which improves the stability of the magnetic ring and avoids the magnetic ring from rotating due to the inertial force of the rotating roller, which would cause uneven magnetic force.

[0028] As a further improvement to the above solution, the roller assembly includes a limiting mechanism movably connected to the upper chuck and the lower chuck. The limiting mechanism includes multiple limiting rods threadedly connected to the upper chuck and the lower chuck, with a ball bearing rotatably connected to one end of each limiting rod.

[0029] The magnetic ring has an annular groove, and the ball bearings are slidably connected in the annular groove.

[0030] By using the above technical solution, the ball bearings at the bottom of the rotating limiting rod are made to fit into the annular groove by rotating the limiting rod, thereby constraining the magnetic ring within the annular groove while ensuring the stability of the rotation of the magnetic ring and the rotating roller.

[0031] Compared with the prior art, this utility model provides a single-path tube-attaching machine, which has the following beneficial effects:

[0032] 1. This single-path tube labeling machine uses strong magnetic rings built into both ends of the rotating roller to generate directional magnetoresistance effect, which suppresses the residual inertial rotation after the iron can stops rotating, prevents the can from generating inertial micro-rotation, and effectively improves the accuracy of the labeling position with the help of the chuck positioning photoelectric eye that provides real-time angle feedback.

[0033] 2. This single-path tube-applying machine has a connecting rod mechanism inside the rotating roller. Under the elastic force of the internal tension spring, the front end of the connecting rod can be quickly installed into or detached from the connecting hole, making the rotating roller plug-and-play and improving the replacement efficiency of the rotating roller.

[0034] 3. This single-path tube bonding machine has a limiting mechanism set on the upper and lower chucks near the connection hole. When the roller rotates, the ball at the bottom of the limiting rod is in contact with the annular groove opened by the magnetic ring, thereby ensuring the stability of the magnetic ring installation and the rotation of the roller.

[0047] A test tube assembly 6 is fixed on the frame assembly 1. The test tube assembly 6 is located near the inlet of the chuck assembly 2 and is used to detect the container's position.

[0048] A chuck positioning photoelectric sensor assembly 8 is fixed on the frame assembly 1. The chuck positioning photoelectric sensor assembly 8 is connected to the rotating shaft of the chuck assembly 2 and is used to detect the rotation angle. The probe assembly 6 and the chuck positioning photoelectric sensor assembly 8 are connected to the control system. The probe assembly 6 triggers the chuck clamping action, and the chuck positioning photoelectric sensor assembly 8 controls the labeling start position.

[0049] A conveyor belt assembly 9 is fixed on the frame assembly 1. The conveyor belt assembly 9 is used to receive the container output from the outlet assembly 4.

[0050] The conveyor belt assembly 9 is symmetrically provided with guardrail assemblies 7 on both sides. The spacing of the guardrail assemblies 7 is adjustable so that the inner spacing matches the diameter of the tubular container, thereby constraining the movement trajectory of the container.

[0051] The end of the conveyor belt assembly 9 is provided with a bottle separating assembly 11. The bottle separating assembly 11 uses adjustable spacing dials to control the container output interval and separate the output containers.

[0052] Furthermore, a human-machine component 10 is provided on one side of the rack assembly 1. The human-machine component 10 is a container for setting and outputting equipment parameters.

[0053] More specifically, the human-machine interface integrates a touch screen and control buttons, and is electrically connected to the chuck assembly 2, labeling assembly 5, and conveyor belt assembly 9 via a PLC.

[0054] Furthermore, the chuck assembly 2 includes an upper chuck 21, a lower chuck 22, and a roller assembly 24, with multiple roller assemblies 24 disposed between the upper chuck 21 and the lower chuck 22.

[0055] Multiple chuck magnetic seats 23 are distributed on the upper chuck 21 and the lower chuck 22.

[0056] More specifically, the upper chuck 21 and the lower chuck 22 are arranged in parallel relative to each other, and multiple roller assemblies 24 are distributed axially between the upper chuck 21 and the lower chuck 22. The roller assemblies undertake the core power transmission and precise positioning of the tubular container. At the same time, the chuck magnetic seat integrates a magnetic transmission structure, and achieves non-contact power transmission and precise control through magnetic field coupling.

[0057] Furthermore, the roller assembly 24 includes two rollers 241, each roller 241 having a connecting groove 2411 at both ends, and an annular groove 2412 at the interface of the connecting groove 2411.

[0058] A connecting rod mechanism 242 and a deep groove ball bearing 243 are movably connected within the connecting groove 2411, with the connecting rod mechanism 242 movably connected within the deep groove ball bearing 243.

[0059] A magnetic ring 244 is movably connected inside the annular groove 2412, and an installation hole 2441 is provided inside the magnetic ring 244.

[0060] More specifically, each set of roller assemblies 24 clamps and conveys the tubular container through two rollers 241. The deep groove ball bearing 243 converts the rotational friction of the roller 241 into rolling friction, reducing power loss. At the same time, it constrains the radial displacement of the linkage mechanism 242, ensuring the stable rotation of the roller 241. Furthermore, the magnetic rings 244 installed in the annular grooves 2412 at both ends of the roller 241 increase the resistance of the two rollers 241 to the aerosol can by utilizing the magnetic resistance effect, preventing the can from rotating again after positioning and improving positioning accuracy.

[0061] Furthermore, the linkage mechanism 242 includes a base 2421 fixed in the connecting groove 2411, a rotating knob 2422 rotatably connected to the base 2421, and a connecting rod 2423 movably connected to the rotating knob 2422.

[0062] The upper chuck 21 and the lower chuck 22 have connecting holes 221 opposite to each other. The connecting rod 2423 is movably sleeved in the mounting hole 2441 and the connecting hole 221, and is fixed in the inner ring of the deep groove ball bearing 243.

[0063] More specifically, when the connecting rod 2423 rotates, it drives the inner ring of the deep groove ball bearing 243 to rotate, reducing the frictional resistance of the connecting rod 2423. At the same time, the stability of the rotation of the connecting rod 2423 is ensured through the mounting hole 2441 and the connecting hole 221.

[0064] Furthermore, a tension spring 2426 is movably connected between the connecting rod 2423 and the rotating knob 2422.

[0065] More specifically, the tension spring 2426 is used to push the connecting rod 2423 so that the front end of the connecting rod 2423 is inserted into the corresponding connecting hole 221. When disassembling and assembling the rotating roller 241, the connecting rod 2423 is pressed to disengage its front end from the connecting hole 221, thereby removing the corresponding rotating roller 241 from between the upper chuck 21 and the lower chuck 22.

[0066] Furthermore, a stabilizing groove 2424 is provided on the rotating knob 2422, and a stabilizing knob 2425 is fixed at the bottom of the connecting rod 2423. The stabilizing knob 2425 is movably sleeved in the stabilizing groove 2424.

[0067] More specifically, when the connecting rod 2423 is pressed, the bottom stabilizing button 2425 moves up and down within the stabilizing groove 2424, thereby ensuring the stability of the connecting rod 2423 when it is disengaged from and installed from the upper chuck 21 and the lower chuck 22.

[0068] Furthermore, a protruding button 2413 is provided in the annular groove 2412, and a groove 2442 is provided on the side of the magnetic ring 244, which is engaged with the side of the protruding button 2413.

[0069] More specifically, the magnetic ring 244 uses a ring-shaped strong magnet. When the magnetic ring 244 is installed in the annular groove 2412, it is engaged with the side of the protrusion 2413 through the side groove 2442, which improves the stability of the magnetic ring 244 and prevents the magnetic ring 244 from rotating due to the inertial force of the rotating roller 241, thus avoiding uneven magnetic force.

[0070] Furthermore, the roller assembly 24 includes a limiting mechanism 245 movably connected to the upper chuck 21 and the lower chuck 22. The limiting mechanism 245 includes a plurality of limiting rods 2451 threadedly connected to the upper chuck 21 and the lower chuck 22, and a ball bearing 2452 is rotatably connected to one end of the limiting rod 2451.

[0071] The magnetic ring 244 has an annular groove 2443, and the ball bearing 2452 is slidably connected in the annular groove 2443.

[0072] More specifically, by rotating the limiting rod 2451, the ball 2452 at its bottom end is made to fit into the annular groove 2443, thereby constraining the magnetic ring 244 within the annular groove 2443 while ensuring the stability of the rotation of the magnetic ring 244 and the rotating roller 241.

[0073] The working principle of the single-path tube applicator proposed in this embodiment is as follows: During use, the tubular container (tin can) is pushed to the station of the positioning component 3 by the feeding mechanism. The positioning component 3 adjusts the position of the container through the guide rail mechanism so that its axis is aligned with the clamping center of the chuck component 2. After the tube measuring component 6 detects that the container is in place, it sends a signal to the control system to trigger the clamping action of the chuck component 2. During clamping, the container enters between the upper chuck 21 and the lower chuck 22. The two rotating rollers 241 of the rotating roller assembly 24 clamp and transfer the container, and the magnetic resistance effect of the magnetic ring 244 increases the resistance of the two rotating rollers 241 to the aerosol tin can, preventing the tin can from rotating again after being positioned, thus improving the efficiency. For positioning accuracy, during transfer, the chuck positioning photoelectric eye assembly 8 detects the chuck rotation angle in real time to control the labeling start position. The peeling mechanism of the labeling assembly 5 releases the label, and the pressing mechanism presses the label onto the rotating container surface. At this time, the roller 241 uses the deep groove ball bearing 243 to provide uniform rolling friction for the container, ensuring uniform rotation. The magnetic ring 244 generates additional magnetic resistance on the iron container, suppressing label misalignment caused by inertial rotation. After labeling is completed, the push rod of the tube outlet assembly 4 pushes the container vertically onto the conveyor belt assembly 9. The guardrail assembly 7 constrains the container trajectory to prevent deviation, and the bottle separating assembly separates the containers at a set interval through the dial wheel to avoid accumulation.

[0074] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
