Description

Technical Field

[0001] This utility model relates to the field of foam laminating machine technology, specifically a foam laminating machine with positioning function. Background Technology

[0002] Foam laminating machines can precisely bond foam to other materials. Through mechanical structure and control system, they ensure the accuracy of bonding and effectively avoid problems such as offset and misalignment that are easy to occur when bonding manually. For example, when producing sealing foam for electronic devices, laminating machines can tightly bond foam that is only a few millimeters thick to plastic shells or release paper, and the error can be controlled within a very small range to ensure the sealing effect.

[0003] When bonding release paper and foam, the long release paper needs to be cut at equal intervals. However, during the cutting process, due to the layered structure of the internal fibers of the paper, the surface tension may cause the paper to delaminate during the cutting process. This may cause the cut to deviate, cut into the foam, or form a wavy unevenness at the cut edge, affecting the appearance of the product.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

The bottom surface of the positioning plates is provided with positioning rods. The positioning rods have telescopic cavities, and a shrinking rod is slidably connected in the telescopic cavities. The bottom end of the shrinking rod is lower than the cutting blade, and a spring is provided between the shrinking rod and the telescopic cavity.

[0007] Furthermore, a suction cup is provided at the lower end of the retractable rod.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A foam laminating machine with positioning function includes a laminating platform 1, laminating pressure rollers 2, a cutting frame 5, and a lifting frame 6. Two cutting frames 5 are symmetrically arranged on both sides of the lifting frame 6. T-shaped grooves are opened in the cutting frames 5. T-shaped blocks are provided at both ends of the lifting frame 6. A motor 602 is installed at the top of the cutting frame 5. The output shaft of the motor 602 is connected to a threaded column. The threaded column is threadedly connected to one end of the lifting frame 6. A foam frame 3 is provided on the top surface of the laminating platform 1. There are multiple laminating pressure rollers 2, which are spaced apart between the foam frame 3 and the cutting frame 5. A release film frame 4 is provided on one side of the laminating platform 1.

[0025] First, place the foam to be bonded on the foam holder 3, and the release film holder 4 is located on one side of the bonding platform 1 to receive the bonded foam.

[0026] After the equipment is started, multiple bonding rollers 2 rotate, gradually conveying the foam on the instant noodle rack 3 to the cutting rack 5 and performing bonding operations, so that the foam is bonded together with the release film, etc.

[0027] When it is necessary to cut the laminated foam, motor 602 starts, driving the threaded column to rotate.

[0028] Because the threaded column is threaded to one end of the lifting frame 6, and the two ends of the lifting frame 6 are engaged with the T-slot of the cutting frame 5 through T-blocks, the lifting frame 6 can rise and fall smoothly on the cutting frame 5. As the lifting frame 6 descends, the cutting blade 601 on its bottom surface gradually approaches the foam to cut it.

[0029] The T-slots and T-blocks of the cutting frame 5 and the lifting frame 6, along with the design of the motor 602 driving the threaded column to lift the lifting frame 6, ensure that the lifting frame 6 lifts and lowers smoothly and reliably, and that the cutting blade 601 can accurately perform the cutting action.

[0030] Furthermore, a notch is provided below the cutting blade 601.

[0031] The notch below the cutting blade 601 provides space for the cutting blade 601 to descend, allowing the cutting blade 601 to completely penetrate the foam and release film, resulting in a more thorough cut.

[0032] The bottom surface of the lifting frame 6 is provided with a cutting blade 601, and the two sides of the lifting frame 6 are provided with positioning plates 7. The bottom surface of the positioning plates 7 is provided with positioning rods 701. The positioning rods 701 have telescopic cavities 703. A retractable rod 702 is slidably connected in the telescopic cavities 703. The bottom end of the retractable rod 702 is lower than the cutting blade 601. A spring 8 is provided between the retractable rod 702 and the telescopic cavity 703.

[0033] There are four positioning plates 7, which are distributed at the four corners of the lifting frame 6.

[0034] During the cutting process, the positioning rod 701 on the bottom surface of the positioning plate 7 first contacts the foam. When the positioning rod 701 contacts the foam, the retraction rod 702 will slide upward relative to the telescopic cavity 703 to compress the spring 8. The compressed spring 8 provides downward pressure to the retraction rod 702, which can position the four corners of the foam and the release film during the cutting process.

[0035] With the cooperation of the positioning plate 7 and its bottom positioning rod 701, shrink rod 702, suction cup 704 and other structures, the foam can be accurately positioned and fixed during cutting, effectively preventing the foam from shifting during the cutting process, greatly improving the cutting accuracy and quality, reducing the product scrap rate caused by cutting deviation, and improving production efficiency.

[0036] Furthermore, a suction cup 704 is provided at the lower end of the retractable rod 702.

[0037] During the foam cutting process, when the lifting frame 6 descends, the positioning rod 701 contacts the foam first.

[0038] Under the action of spring 8, the retraction rod 702 enables the suction cup 704 to fit tightly against the foam surface.

[0039] Because the suction cup 704 can generate negative pressure to adsorb the foam, it can firmly fix the foam on the worktable and prevent the foam from shifting when the cutting blade 601 cuts.

[0040] This is crucial for ensuring cutting accuracy, because if the foam moves during the cutting process, it can lead to problems such as inaccurate cutting dimensions and uneven edges, thus affecting product quality.

[0041] The foam surface may not be completely flat, and the design of the suction cup 704, which can slide along the outer wall of the negative pressure rod 705, allows the suction cup 704 to adapt well to the undulations of the foam surface.

[0042] When the retracting rod 702 slides upward relative to the telescopic cavity 703, the internal space of the suction cup 704 increases, the air pressure decreases, and negative pressure is formed through the air hole 707.

[0043] This adaptive feature ensures that even if the foam surface is uneven, the suction cup 704 can fit tightly against the foam, effectively performing its adsorption and positioning function.

[0044] Four positioning plates 7 are distributed at the four corners of the lifting frame 6, and the suction cups 704 at the bottom of each positioning plate 7 work together.

[0045] This multi-point adsorption method can fix the foam from multiple positions, providing a more stable and uniform positioning effect compared to single-point fixing or simple mechanical clamping.

[0046] It ensures that the foam remains fixed in all directions when the cutting blade 601 is cutting, further improving the accuracy of cutting and the quality of foam processing.

[0047] Furthermore, the bottom surface of the retractable rod 702 is provided with one end of a negative pressure rod 705, which is inserted into the suction cup 704. The other end of the negative pressure rod 705 is connected to a positioning plate 706. The suction cup 704 is provided with an air hole 707, which can slide along the outer wall of the negative pressure rod 705. The area of ​​the air hole 707 is smaller than the bottom area of ​​the retractable rod 702.

[0048] Positioning rod 701 drives retracting rod 702 to move downward.

[0049] In its initial state, the internal air pressure of suction cup 704 is the same as that of the outside air.

[0050] As the retracting rod 702 moves downward, when the bottom surface of the retracting rod 702 touches the air hole 707, the top surface of the suction cup 704 is sealed. At this time, if the retracting rod 702 is pressed down further, the internal space of the suction cup 704 is compressed, and the air can only be slowly discharged through the tiny gap between the negative pressure rod 705 and the suction cup 704 (because the air hole 707 has been sealed), thereby gradually reducing the air pressure inside the suction cup 704 and forming a negative pressure.

[0051] Under negative pressure, the suction cup 704 tightly adheres to the foam and release film, thus fixing them in place.

[0052] After the cutting is completed, the lifting frame 6 rises, the negative pressure rod 705 moves upwards, and the retraction rod 702 moves away from the air hole 707. At this time, the internal space of the suction cup 704 is reconnected with the outside world, the internal and external air pressures are restored to balance, and there is no longer negative pressure adsorption force, so the foam and release film can be easily lifted to complete one cutting and positioning operation cycle.

[0053] The above design, through the negative pressure generated by the shrink rod 702 and the air hole 707, can quickly and stably adsorb and fix the foam and release film. During the cutting process, it effectively prevents the displacement of the foam and release film, ensuring cutting accuracy. After the cutting is completed, the adsorption is automatically canceled to prevent the foam and release film from shifting due to the negative pressure when lifting.

[0054] Moreover, compared to some complex vacuum adsorption systems, this structure is simple and compact, with lower cost, yet it still achieves reliable adsorption function, improving the cost-effectiveness of the equipment.
