Description

Technical Field

[0001] The utility model relates to an electrostatic film forming die, in particular to an electrostatic film forming die, and belongs to the technical field of electrostatic films. Background Art

[0002] An electrostatic film is a film formed by static electricity between two different media. Its basic composition is an electrostatic film composed of a high surface tension medium attached to a low surface tension medium.

[0003] After the electrostatic film is processed and produced, it is rolled up to facilitate subsequent processing. During the subsequent processing, the electrostatic film is die-cut according to product requirements to form finished products of various shapes and sizes.

[0004] At present, the existing technology requires the use of a forming mold when performing the cutting and forming processing of the electrostatic film. The electrostatic film is spread flat on the forming mold and cut and formed by a film cutting machine. In the existing technology, the electrostatic film is transported by a winder and intermittent cutting is performed. However, when cutting, the cutter contacts the electrostatic film, resulting in the electrostatic film being stretched during the cutting process, resulting in poor precision of the cut product and low pass rate. Therefore, we propose an electrostatic film forming mold. Utility Model Content

[0007] The transmission unit includes a first rotating rod and a second rotating rod rotatably connected to the forming plate and the mold main plate, and a connecting seat is rotatably connected between the first rotating rod and the second rotating rod;

[0008] The connecting seat is provided with an extrusion unit, which includes a sliding rod slidably connected to the connecting seat, and the bottom end surface of the sliding rod is fixedly connected to the extrusion seat.

[0009] Preferably, a cutting mechanism is fixedly connected to the film cutting machine, and the cutting mechanism is located directly above the forming plate.

[0013] Preferably, a spring is sleeved on the outer peripheral wall of the sliding rod.

[0014] Preferably, both ends of the spring are fixedly connected to the connecting seat and the extrusion seat respectively.

[0015] The beneficial effect of the present invention is that when the forming plate moves, the connecting seat moves under the action of the first rotating rod and the second rotating rod, so that the connecting seat compresses the spring. Under the rebound of the spring, the spring pushes the extrusion seat to drive the extrusion roller and the electrostatic film to tighten the electrostatic film, thereby avoiding deformation of the electrostatic film during cutting.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model discloses an electrostatic film forming die according to the attached Figure 1-3As shown, it includes a mold main board 3, a forming plate 4 and a transmission unit 5. The mold main board 3 is fixedly connected to the film cutting machine 1. The mold main board 3 is fixedly installed on the film cutting machine 1. The forming plate 4 is slidably connected to the mold main board 3. The transmission unit 5 is between the forming plate 4 and the mold main board 3.

[0022] The transmission unit 5 includes a first rotating rod 502 and a second rotating rod 503 rotatably connected to the forming plate 4 and the mold main plate 3. A connecting seat 501 is rotatably connected between the first rotating rod 502 and the second rotating rod 503. When the forming plate 4 slides outward from the cutting mechanism 2, the forming plate 4 drives the first rotating rod 502 to move and rotate. At this time, the first rotating rod 502 pushes the connecting seat 501 to move. Under the movement of the connecting seat 501, the connecting seat 501 drives the first rotating rod 502 and the second rotating rod 503 to rotate simultaneously. At this time, the first rotating rod 502 moves upward, driving the extrusion seat 603 to move upward;

[0023] The connecting seat 501 is provided with an extrusion unit 6, which includes a sliding rod 602 slidably connected to the connecting seat 501, and the bottom end face of the sliding rod 602 is fixedly connected to the extrusion seat 603. When the forming plate 4 moves, the connecting seat 501 moves under the action of the first rotating rod 502 and the second rotating rod 503, so that the connecting seat 501 compresses the spring 604. Under the rebound of the spring 604, the spring 604 pushes the extrusion seat 603 to drive the extrusion roller 601 and the electrostatic film to tighten the electrostatic film to avoid deformation of the electrostatic film during cutting. At this time, when the electrostatic film is cut by the cutting mechanism 2, the stability of the electrostatic film forming is guaranteed, so that the precision of the cut product is high, and the qualified rate of the electrostatic film forming is improved.

[0024] The film cutting machine 1 is fixedly connected to a cutting mechanism 2 , which is located directly above the forming plate 4 . The electrostatic film is cut and formed by a cutter on the cutting mechanism 2 .

[0025] A driving shaft is provided on the mold main board 3, and the driving shaft is connected to the forming plate 4 by transmission. The forming plate 4 is driven to move by the driving shaft, so that the forming plate 4 is moved to the outside of the cutting mechanism 2, which is convenient for the installation of the electrostatic film. Then, the forming plate 4 is moved to the cutting mechanism 2, and the electrostatic film is driven to move by the winding mechanism, and at the same time, the electrostatic film is cut and formed in cooperation with the cutter on the cutting mechanism 2.

[0026] The top end surface of the mold main board 3 is fitted with multiple extrusion seats 603, and the extrusion seats 603 are fixedly connected to the ends of the sliding rods 602. When the forming plate 4 slides outward from the cutting mechanism 2, the forming plate 4 drives the first rotating rod 502 to move and rotate. At this time, the first rotating rod 502 pushes the connecting seat 501 to move. Under the movement of the connecting seat 501, the connecting seat 501 drives the first rotating rod 502 and the second rotating rod 503 to rotate at the same time. At this time, the first rotating rod 502 moves upward, driving the extrusion seat 603 to move upward.

[0027] The squeezing rollers 601 are rotatably connected between the multiple squeezing seats 603. When the squeezing seats 603 move upward, the squeezing rollers 601 move. At this time, the squeezing rollers 601 are separated from the electrostatic film, and the electrostatic film can be easily installed or removed.

[0028] The outer wall of the sliding rod 602 is sleeved with a spring 604. When the electrostatic film is installed, it is moved to the bottom of the cutting mechanism 2 through the forming plate 4, so that the extrusion seat 603 and the extrusion roller 601 move. When the extrusion roller 601 contacts the electrostatic film, the extrusion roller 601 contacts and squeezes the electrostatic film.

[0029] The two ends of the spring 604 are fixedly connected to the connecting seat 501 and the extrusion seat 603 respectively. At this time, the connecting seat 501 moves under the action of the first rotating rod 502 and the second rotating rod 503, so that the connecting seat 501 compresses the spring 604. Under the rebound of the spring 604, the spring 604 pushes the extrusion seat 603 to drive the extrusion roller 601 to squeeze the electrostatic film, and tighten the electrostatic film. At this time, when the electrostatic film is cut by the cutting mechanism 2, the stability of the electrostatic film forming is guaranteed, so that the qualified rate of the electrostatic film forming is improved.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
