[0024] The following is combined Figure 1The present invention provides a detailed description of a labeling machine for preventing label rolls from splitting together, through specific embodiments and application scenarios.
[0025] like Figure 1 As shown, this utility model provides a labeling machine for preventing label rolls from sticking together, including: a labeling frame 1, a label roll 2, a brake 3, and a traction assembly 4. The label roll 2 is rotatably mounted on the labeling frame 1, the brake 3 is hinged to the labeling frame 1, and the traction assembly 4 is connected to the brake 3. The traction assembly 4 is used to drive the brake 3 and the label roll 2 to abut or separate.
[0026] Understandably, the label roll 2 is located on the labeling rack 1. The label roll 2 can be a polyethylene annular disc. The labeling rack 1 is equipped with a motor and a roller. The drive end of the motor is connected to the roller, driving the roller to rotate. The label roll 2 is fitted onto the outside of the roller so that it rotates with the roller. The label roll 100 is fitted onto the roller, and the label roll 2 is located at the bottom of the label roll 100 to support it. The roller drives the label roll 100 to unwind, and the unwound label paper 101 moves along a preset path to the labeling area.
[0027] like Figure 1 As shown, the brake component 3 is elongated. Optionally, the brake component 3 is an aluminum alloy block. The brake component 3 is located beside the label roll 2. One end of the brake component 3 is hinged to the labeling frame 1, and the other end is rotatable relative to the labeling frame 1. The traction assembly 4 is connected to the brake component 3 and is used to traction the movement of the brake component 3. When the labeling machine is working normally, the label roll 2 rotates with the roller. At this time, the traction assembly 4 drives the brake component 3 to move away from the label roll 2, so that the brake component 3 and the label roll 2 are separated. When the labeling machine stops, the label roll 2 brakes urgently. At this time, the traction assembly 4 drives the brake component 3 to move closer to the label roll 2, so that the brake component 3 and the outer peripheral wall of the label roll 2 abut against each other. This allows the label roll 2 to stop moving immediately under the resistance of the brake component 3, avoiding the phenomenon of label rolls 100 on the label roll 2 sticking together, reducing the waste rate of label paper 101, and ensuring the labeling efficiency of the labeling machine.
[0028] This utility model provides a labeling machine for preventing label rolls from sticking together. The label roll 2 is rotatably mounted on the labeling frame 1 to drive the label roll 100 mounted on the label roll 2 to unwind. The brake 3 is hinged to the labeling frame 1 and located beside the label roll 2. The traction component 4 is connected to the brake 3 so that when the label roll 2 is working normally, it drives the brake 3 to move away from the label roll 2 so that the brake 3 can avoid the label roll 2. When the label roll 2 stops in an emergency, the traction component 4 drives the brake 3 to move closer to the label roll 2 so that the brake 3 and the label roll 2 come into contact, and the label roll 2 can stop moving immediately. This avoids the phenomenon of label rolls sticking together because the label roll 2 cannot stop rotating in time due to inertia, and reduces labeling failures of the labeling machine.
[0029] In some embodiments, such as Figure 1 As shown, the traction assembly 4 includes a pusher 41 and a spring 42. The pusher 41 is connected to the brake 3 and is used to push the brake 3 to move away from the label reel 2. The spring 42 is fixed to the label holder 1 and is located on the side of the brake 3 closer to the label reel 2. The spring 42 and the brake 3 are connected.
[0030] Understandably, the traction component 4 can be a handle fixed to the brake component 3. When the user needs to avoid the reel 2, he / she pushes the brake component 3 away from the reel 2. When he / she needs to stop the reel 2 from continuing to rotate, he / she pushes the brake component 3 towards the reel 2 so that the brake component 3 and the reel 2 come into contact.
[0031] In the case where the traction assembly 4 includes a pusher 41 and a spring 42, such as Figure 1 As shown, the pusher 41 and the brake 3 are connected, and the pusher 41 is used to push the brake 3 to move away from the label reel 2. The spring 42 is located between the label reel 2 and the brake 3. Specifically, one end of the spring 42 is fixedly connected to the label holder 1, and the other end is connected to the side of the brake 3 near the label reel 2. When the label reel 2 is working normally, the pusher 41 pushes the label reel 2 to move away from the label reel 2, at which time the spring 42 is in a stretched state. When the label reel 2 stops, the pusher 41 stops exerting force on the brake 3, and at this time, under the tension of the spring 42, the brake 3 and the label reel 2 come into contact.
[0032] Optional, such as Figure 1 As shown, the pushing member 41 is a roller. The roller can contact the unwound label paper 101 of the label roll 100 mounted on the label roll 2, and the roller is rotatably mounted on the braking member 3. When the label paper 101 is in a tensioned state, the roller, pushed by the label paper 101, drives the braking member 3 to move away from the label roll 2.
[0033] Understandably, the roller can be a guide roller positioned on a predetermined path of the label paper 101. The roller is rotatably mounted on the brake 3. The roller has a roller surface for overlapping the label paper 101. When the label reel 2 is operating normally, the label paper 101 is in a taut state. At this time, the label paper 101 and the roller are in close contact. Under the action of the label paper 101, the roller moves in a direction away from the label reel 2, thereby causing the brake 3 to separate from the label reel 2.
[0034] When the labeling machine stops, the label paper 101 switches from a tensioned state to a relaxed state, at which point the label paper 101 separates from the roller. Under the tension of the spring 42, the brake 3 moves towards the label roll 2 until it contacts the label roll 2.
[0035] Specifically, the labeling machine for preventing label rolls from sticking together also includes a tear-off component and a rewinding tray. The tear-off component is located between the label roll rewinding tray 2 and the rewinding tray, and is used to tear off the labels on the label paper 101. The rewinding tray is rotatably mounted on the labeling frame 1 and is used to rewind the label paper 101.
[0036] Understandably, the tear-off device is located on the label holder 1, between the label roll reel 2 and the take-up reel. The tear-off device is used to tear off the label from the label paper 101 and stick it to the corresponding position.
[0037] Understandably, during production, the label 101 is adhered to a protective layer. This protective layer provides physical protection for the label, preventing damage and facilitating transportation and storage. The label 101 is wound around the label roll 100.
[0038] Before starting the labeling machine, the protective layer at the end of the label roll 100 is manually torn off. Next, the end of the protective layer is manually wound onto the take-up shaft of the reel. Finally, the labeling machine is started, and the unwound label sheets 101 from the label roll 100 are sequentially placed on multiple guide rollers. The label is then torn off and adhered to the corresponding position using the tear-off mechanism. The take-up shaft of the reel is used to rewind the protective layer for recycling. These components work together to enable the labeling machine to efficiently apply labels to products or packaging, improving production efficiency and product quality.
[0039] In other embodiments, the traction assembly 4 is an electric push rod. The electric push rod is fixed to the label holder 1, and the drive end of the electric push rod is connected to the brake component 3.
[0040] Specifically, the electric linear actuator includes a drive motor, a lead screw transmission mechanism, and a rod body. The output end of the drive motor is connected to the lead screw of the lead screw transmission mechanism, the lead screw nut of the lead screw transmission mechanism is connected to the rod body, and the rod body is connected to the brake component 3. The drive motor drives the lead screw transmission mechanism to operate, and the lead screw transmission mechanism drives the rod body to move linearly, thereby switching the contact or separation between the brake component 3 and the standard reel 2.
[0041] Furthermore, in some embodiments, such as Figure 1 As shown, the brake component 3 has a groove 31 on the side near the reel 2. When the brake component 3 and the reel 2 are in contact, the two sides of the groove 31 abut against different positions on the reel 2.
[0042] Understandably, the groove 31 is located on one side of the brake component 3 near the reel 2. The end faces on both sides of the groove 31 are used to abut against different positions on the outer peripheral wall of the reel 2, so as to achieve effective braking of the reel 2 by the brake component 3.
[0043] Preferably, the groove 31 is an arc-shaped groove.
[0044] The curvature of the arc groove is adapted to the curvature of the outer edge of the standard roll 2 so that when the brake component 3 and the standard roll 2 are in contact, the groove wall of the arc groove can contact the standard roll 2, increasing the contact area between the standard roll 2 and the brake component 3, and ensuring the braking effect of the brake component 3 on the standard roll 2.
[0045] In other embodiments, the brake component 3 has an anti-slip structure on the side near the reel 2. The anti-slip structure is used to abut against the outer wall of the reel 2 to increase the friction between the brake component 3 and the reel 2, ensuring the braking effect of the brake component 3 on the reel 2. Optionally, the anti-slip structure is a serrated structure or an anti-slip texture.
[0046] The brake component 3 is hinged to the label holder 1 via a pin 5. One end of the brake component 3 has a first connecting hole. Correspondingly, the label holder 1 has a second connecting hole. The pin 5 passes through the first and second connecting holes in sequence to connect the brake component 3 and the label holder 1 together. The size of the first connecting hole is slightly larger than the outer diameter of the pin 5, so that the brake component 3 can rotate relative to the label holder 1, thereby allowing the brake component 3 to move towards or away from the label roll 2.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
