Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and more specifically, to a labeling machine that integrates film cutting and labeling. Background Technology

[0002] Shrink wrapping is a widely used packaging method for products in many fields such as food, daily chemicals, and electronics. It not only protects products from external contamination and moisture damage, but also improves the neatness and aesthetics of the product's appearance. To facilitate consumers' quick removal of the shrink film from the product, the current practice is generally to first cut a small slit in the shrink film on the product surface for easy tearing, and then cover the tear with a label displaying key information such as product brand information, product specifications, production date, and anti-counterfeiting code. In this way, the cut can be hidden by the label, improving the integrity of the packaging, and the label can also guide consumers to quickly find the tear position.

[0003] However, most film cutting and labeling devices currently on the market are separate designs. This separate structure results in the output positions of the two devices being independent, which exposes significant drawbacks in actual production:

[0004] Because the film cutting device and the labeling mechanism are set up separately, the staff needs to repeatedly adjust the installation position, working angle and product conveying path of the two devices to make the output position of the film cutting device as consistent as possible with the output position of the labeling device. However, due to the precision limitations of the split structure, it is difficult for the two to achieve precise matching at the same point. Moreover, during the process of conveying the product from the film cutting device to the labeling device for labeling, the product is prone to lateral displacement, longitudinal rotation or angular deflection due to factors such as conveyor belt vibration, uneven friction, and wear of positioning components. This further aggravates the situation that the output position of the labeling device cannot accurately correspond to the output position of the previous film cutting mechanism, causing the label coverage position to deviate from the film cut. If the cut is not completely covered by the label, the uncovered cut is prone to widening cracks, dust, water, and contact with stains, which can damage the product inside the packaging and affect the stability of product quality and market competitiveness.

[0005] In conclusion, it is necessary to develop an integrated film cutting and labeling machine to solve the problems of low debugging efficiency and production misalignment caused by the difficulty of the existing separate film cutting and labeling devices outputting at the same point. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] The purpose of this utility model is to provide a labeling machine that integrates film cutting and labeling, and at least solves the technical problem of how to improve production efficiency and ensure that the labeling position and the cutting position coincide.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a labeling machine that integrates film cutting and labeling, comprising:

[0010] support;

[0011] The device includes a film cutting device, a labeling device, and a driving device. The film cutting device is located on one side of the labeling device, and the driving device is located on the support and is connected to the film cutting device and the labeling device for transmission.

[0012] The drive unit is used to drive the film cutting device and the labeling device to reciprocate between the label feeding station and the labeling station. The film cutting device is used to cut the shrink film to form an opening in the shrink film. The labeling device is used to pick up or apply the label.

[0013] In a further configuration, the aforementioned film cutting device includes a cutter and a cutter drive. The cutter drive is located on the output end of the drive device and is connected to the cutter via transmission. The cutter drive is used to drive the cutter to move toward or away from the shrink film at the labeling station, so as to cut the shrink film and form an opening on the shrink film.

[0014] In a further configuration, the aforementioned labeling device includes an adsorption block and an adsorption block drive. The adsorption block drive is located on the output end of the drive device and is connected to the adsorption block in a transmission manner. The adsorption block drive is used to drive the adsorption block to move toward or away from the label feeding station or labeling station in order to grab or affix the label.

[0015] Furthermore, the movement trajectories of the aforementioned adsorption block and cutter are arranged to intersect, so that the cut coincides with the label attachment position;

[0016] When the movement trajectory of the cutter is set to be inclined, the movement trajectory of the adsorption block is set to be vertical or inclined; when the movement trajectory of the adsorption block is set to be inclined, the movement trajectory of the cutter is set to be vertical or inclined.

[0017] Furthermore, the aforementioned adsorption block has multiple adsorption holes evenly distributed on one side. These adsorption holes are used to adsorb labels. The adsorption block also has air guide holes that are connected to the adsorption holes and are used to connect an external air intake device to provide adsorption force to the adsorption block.

[0018] Furthermore, the aforementioned film-cutting device also includes:

[0019] The slider is slidably disposed on the output end of the drive device and fixedly connected to the cutter drive component, so that the cutter drive component is disposed on the output end of the drive device;

[0020] A fixing block is fixed to the output end of the drive device;

[0021] A limit rod is fixed to one side of the slider;

[0022] An elastic element is sleeved outside the limiting rod. The two ends of the elastic element are connected to the slider and the fixed block, respectively. The elastic element has an elastic force that drives the slider to slide away from the fixed block.

[0023] Further, the aforementioned drive device includes:

[0024] The X-axis moving mechanism is mounted on the support.

[0025] The Y-axis moving mechanism is located at the output end of the X-axis moving mechanism;

[0026] The Z-axis moving mechanism is located on the output end of the Y-axis moving mechanism and is connected to the film cutting device and the labeling device via transmission.

[0027] The X-axis moving mechanism and the Y-axis moving mechanism are combined to drive the Z-axis moving mechanism to move above the label feeding station or labeling station. The Z-axis moving mechanism is used to drive the lifting displacement of the film cutting device and the labeling device.

[0028] (III) Beneficial Effects

[0029] Compared with the prior art, the beneficial effects of the technical solution provided in this application include:

[0030] The integrated film-cutting and labeling machine provided by this utility model operates as follows: First, the drive device moves the film-cutting device and the labeling device to the label feeding station, where the labeling device picks up the label. Next, the drive device moves the film-cutting device and the labeling device from the label feeding station to the labeling station. Then, the film-cutting device cuts the shrink film at the labeling station. Finally, the labeling device applies the label to the cut on the shrink film at the labeling station. It can be seen that both the film-cutting device and the labeling device are installed on the output end of the drive device. The drive device can synchronously transfer the film-cutting device and the labeling device, allowing the film-cutting and labeling processes to be completed consecutively at the same point. This ensures that the label is accurately applied to the cut on the shrink film, completely sealing the cut and ensuring that the labeling position and the cut position coincide. This eliminates the need for manual adjustment of the labeling position and the cut position, effectively improving production efficiency and ensuring the integrity of the product packaging.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] See Figure 1 , Figure 1 The figure shows a perspective view of the integrated film cutting and labeling machine in the embodiment. The integrated film cutting and labeling machine includes a support 1, a film cutting device 2, a labeling device 3, and a driving device 4.

[0044] The film cutting device 2 is installed on one side of the labeling device 3. The drive device 4 is installed on the bracket 1 and is connected to the film cutting device 2 and the labeling device 3 for transmission.

[0045] The drive unit 4 drives the film cutting unit 2 and the labeling unit 3 to reciprocate between the label loading station 5 and the labeling station 6. The film cutting unit 2 cuts the shrink film to form an incision. The labeling unit 3 picks up or applies labels.

[0046] When using the integrated film cutting and labeling machine described above, firstly, the drive device 4 drives the film cutting device 2 and the labeling device 3 to the label loading station 5, where the labeling device 3 picks up the label. Next, the drive device 4 drives the film cutting device 2 and the labeling device 3 from the label loading station 5 to the labeling station 6. Then, the film cutting device 2 cuts the shrink film on the labeling station 6. Finally, the labeling device 3 completes the labeling on the cut of the shrink film on the labeling station 6. It can be seen that the film cutting device 2 and the labeling device 3 of this invention are both installed on the output end of the drive device 4. The drive device 4 can synchronously transfer the film cutting device 2 and the labeling device 3, allowing the film cutting and labeling processes to be completed consecutively at the same point. This ensures that the label is accurately attached to the cut of the shrink film, completely sealing the cut and ensuring that the labeling position and the cut position coincide. This eliminates the need for manual adjustment of the labeling position and the cut position, effectively improving production efficiency and ensuring the integrity of the product packaging.

[0047] See Figure 1 and Figure 2 In one embodiment of the film cutting device 2, the film cutting device 2 includes a cutter 21 and a cutter drive 22. The cutter drive 22 is mounted on the output end of the drive device 4 by means of screwing or welding, and is connected to the cutter 21 in a transmission manner. The cutter drive 22 is used to drive the cutter 21 to move toward or away from the shrink film on the labeling station 6, so as to cut the shrink film and form a cut on the shrink film. Thus, when the drive device 4 moves the film cutting device 2 to the labeling station 6, the cutter drive 22 drives the cutter 21 to move toward the shrink film on the labeling station 6, so as to cut the shrink film covering the outer surface of the product and form a cut. After the film cutting is completed, the cutter drive 22 drives the cutter 21 to move away from the shrink film and return to its original position to prepare for the next film cutting. It can be seen that the film cutting device 2 can realize automatic film cutting through the cooperation of the cutter drive 22 and the cutter 21.

[0048] The aforementioned cutter 21 can be used for cutting operations with existing straight vibrating cutters, flat-edged cutters, or hot-melt cutters. The aforementioned cutter drive unit 22 can be used with existing light-load drive structures such as pneumatic cylinders or small stepper motor-screw modules, and its output end is connected to the cutter 21 by means of screwing or snap-fitting.

[0049] See Figure 1 and Figure 3In one embodiment of the labeling device 3, the labeling device 3 includes an adsorption block 31 and an adsorption block drive 32. The adsorption block drive 32 is mounted on the output end of the drive device 4 by means of screwing or welding, and is connected to the adsorption block 31 in a driving manner. The adsorption block drive 32 is used to drive the adsorption block 31 to move toward or away from the label feeding station 5 or the labeling station 6, so as to grasp or affix the label. As can be seen, when the driving device 4 drives the labeling device 3 to move to the label loading station 5, the adsorption block driving component 32 drives the adsorption block 31 to move towards the label on the label loading station 5, so that the adsorption block 31 adheres to the label surface; the adsorption block 31 adsorbs the label while adhering to the label surface; after adsorption is completed, the adsorption block driving component 32 drives the adsorption block 31 to move away from the label loading station 5; when the driving device 4 drives the labeling device 3 to move to the labeling station 6, the adsorption block driving component 32 drives the adsorption block 31 with the adsorbed label to move towards the shrink film on the labeling station 6, so that the label on the adsorption block 31 adheres to the surface of the shrink film to complete the labeling; after the label is attached, the adsorption block driving component 32 drives the adsorption block 31 to move away from the shrink film on the labeling station 6. In this way, the adsorption block driving component 32 drives the adsorption block 31 to move along a preset trajectory to ensure that the label is stably gripped and accurately attached.

[0050] The aforementioned adsorption block 31 can use existing adsorption components such as vacuum suction cups or electromagnetic adsorption blocks. The aforementioned adsorption block drive component 32 can use existing light-load drive structures such as pneumatic cylinders or small stepper motor-screw modules, and its output end is connected to the adsorption block 31 by means of screwing or snap-fitting.

[0051] See Figure 2 , Figure 3 and Figure 4 Based on the above embodiment, the moving trajectories of the adsorption block 31 and the cutter 21 are arranged to intersect, so that the cut coincides with the label attachment position. Specifically, when the moving trajectory of the cutter 21 is inclined, the moving trajectory of the adsorption block 31 is either vertical or inclined. Figure 4 The diagram illustrates a configuration where, in one embodiment described above, the movement trajectory of the adsorption block 31 is vertical and the movement trajectory of the cutter 21 is inclined. The cutter 21 moves to the point where its movement trajectory intersects with that of the adsorption block 31. By designing the movement trajectories of the adsorption block 31 and / or the cutter 21 to be inclined, the intersection of their trajectories is ensured, allowing the cut position to coincide with the labeling position. This ensures the label accurately covers the cut, effectively improving packaging integrity and further enhancing market competitiveness.

[0052] See Figure 3Based on the above embodiments, a plurality of adsorption holes 33 are evenly distributed on one side of the adsorption block 31. The adsorption holes 33 are used to adsorb labels. An air guide hole 34 is also provided on the adsorption block 31. The air guide hole 34 is connected to the adsorption holes 33 and is used to connect an external air suction device to provide adsorption force to the adsorption block 31. In this way, the air guide hole 34 is connected to all adsorption holes 33 to form a unified air channel, so that the airflow generated by the external air suction device can be quickly and evenly transmitted to each adsorption hole 33. The plurality of adsorption holes 33 evenly distributed on one side of the adsorption block 31 can make the label adhere to the adsorption block 31 evenly under force, avoiding uneven local force that may cause the label to wrinkle, skew or fall off, ensuring the smooth progress of subsequent labeling transfer, bonding and other operations, and further ensuring the integrity of product packaging labeling.

[0053] See Figure 2 Based on the above embodiments, the film cutting device 2 further includes a slider 23, a fixing block 24, a limiting rod 25, and an elastic element 26. The slider 23 is slidably mounted on the output end of the drive device 4 via a slide rail and is fixedly connected to the cutter drive member 22 by means of screwing or welding, so that the cutter drive member 22 is mounted on the output end of the drive device 4. The fixing block 24 is mounted on the output end of the drive device 4 by means of screwing or welding. The limiting rod 25 is welded to one side of the slider 23. The elastic element 26 is sleeved on the limiting rod 25, and both ends of the elastic element 26 are connected to the slider 23 and the fixing block 24 respectively by means of abutment or adhesion. The elastic element 26 has an elastic force that drives the slider 23 to slide away from the fixing block 24. As can be seen, when the cutter drive 22 drives the cutter 21 to cut the shrink film on the labeling station 6, if the cutter 21 overcuts and contacts the product surface below the shrink film, the product surface will apply pressure to the cutter 21. This causes the slider 23 to overcome the elastic force of the elastic element 26 and slide the cutter 21 towards the fixed block 24, preventing the cutter 21 from overcutting and damaging the product. When the cutter drive 22 drives the cutter 21 back to its original position, the slider 23 slides away from the fixed block 24 under the elastic force of the elastic element 26, returning to its original position. In this way, the film cutting device 2 can effectively prevent the cutter 21 from overcutting and damaging the product through this structure.

[0054] The aforementioned elastic element 26 can be a compression spring or a tension spring.

[0055] See Figure 1In one embodiment of the driving device 4, the driving device includes an X-axis moving mechanism 41, a Y-axis moving mechanism 42, and a Z-axis moving mechanism 43. The X-axis moving mechanism 41 is mounted on the bracket 1 by means of screwing or welding. The Y-axis moving mechanism 42 is mounted on the output end of the X-axis moving mechanism 41 by means of screwing or welding. The Z-axis moving mechanism 43 is mounted on the output end of the Y-axis moving mechanism 42 by means of screwing or welding, and the output end of the Z-axis moving mechanism 43 is connected to the film cutting device 2 and the labeling device 3 by means of screwing or welding. The X-axis moving mechanism 41 and the Y-axis moving mechanism 42 are combined to drive the Z-axis moving mechanism 43 to move above the label loading station 5 or the labeling station 6. The Z-axis moving mechanism 43 is used to drive the lifting and lowering displacement of the film cutting device 2 and the labeling device 3. As can be seen, during the cutting and labeling operations, when the X-axis moving mechanism 41 and the Y-axis moving mechanism 42 work together to drive the Z-axis moving mechanism 43 to move above the label loading station 5, the Z-axis moving mechanism 43 drives the film cutting device 2 and the labeling device 3 to move together toward or away from the label loading station 5. When the X-axis moving mechanism 41 and the Y-axis moving mechanism 42 work together to drive the Z-axis moving mechanism to move above the labeling station 6, the Z-axis moving mechanism 43 drives the film cutting device 2 and the labeling device 3 to move together toward or away from the labeling station 6. In this way, the driving device, through the coordinated work of the X-axis moving mechanism 41, the Y-axis moving mechanism 42, and the Z-axis moving mechanism 43, can drive the film cutting device 2 and the labeling device 3 to any position.

[0056] The X-axis moving mechanism 41, Y-axis moving mechanism 42 and Z-axis moving mechanism 43 mentioned above can all use linear drive mechanisms such as telescopic cylinders, stepper motor-lead screw and nut linear modules or servo motor linear modules.
