Description

A glue dot transfer laminating machine Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to an adhesive dot transfer and laminating machine. Background Technology

[0002] Adhesive dot transfer laminating machines are mechanical devices used for material lamination processing. They are mainly used to uniformly transfer adhesive in the form of dots onto the lining fabric, and then laminate it with the outer fabric to form a whole. They can quickly produce high-quality composite materials, greatly improving production efficiency. Adhesive dot transfer laminating machines are widely used in the textile fabric field, such as the lamination of materials like sponge, EVA, blankets, and fabrics.

[0003] Chinese patent CN220280836U discloses an adhesive dot transfer laminating machine, including a base. A vertical plate is fixedly connected to the top wall of the base, a gear ring is fixedly connected to the side wall of the vertical plate, and a rotating shaft is rotatably connected to the side wall of the vertical plate. A turntable is fixedly connected to one end of the rotating shaft, an eccentric rod is fixedly connected to the side wall of the turntable, and a gear is rotatably connected to the side wall of the eccentric rod. The gear meshes with the gear ring. A first connecting rod is rotatably connected to one end of the eccentric rod. A limit block is fixedly connected to the side wall of the vertical plate, and a sliding hole is formed in the side wall of the limit block. A second connecting rod is slidably connected inside the sliding hole, and one end of the second connecting rod is rotatably connected to the end of the first connecting rod away from the eccentric rod. This adhesive dot transfer laminating machine can extrude materials multiple times to avoid incomplete material lamination. By setting up a sliding groove, connecting rod, and buffer spring, the lifting process of the first and second pressure plates is buffered and protected.

[0004] However, the above technical solution has the following shortcomings: when the equipment presses the fabric through the second pressure plate, the springs on both sides of the second pressure plate are prone to have different compression values ​​due to different forces, which in turn affects the uniformity of glue distribution when the fabric is laminated. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an adhesive dot transfer laminating machine that can not only provide a certain buffering and protection during the lifting and lowering process of the pressure plate, but also ensure the stability of the plate surface during the pressing process, thereby improving the quality of the laminating process.

[0010] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] Example 1, as shown in Figures 1-4, proposes an adhesive dot transfer laminating machine, which includes a base 1 and a buffer mechanism; the base 1 is provided with a placement groove 2, and a pressure plate 9 is provided above the placement groove 2.

[0018] The buffer mechanism is mounted on the pressure plate 9 and includes a mounting plate 3, two upper frames 4 and a lower frame 10 respectively mounted on the mounting plate 3 and the pressure plate 9, four movable blocks 6 slidably mounted inside the upper frames 4 and the lower frames 10, a first connecting member 7, a second connecting member 8, a third connecting member 11 and a fourth connecting member 12 mounted on the four movable blocks 6, a first rotating rod 13 rotatably connected at both ends to the first connecting member 7 and the fourth connecting member 12 respectively, a second rotating rod 14 rotatably connected at both ends to the second connecting member 8 and the third connecting member 11 respectively, a connecting shaft 15 passing through the first rotating rod 13 and the second rotating rod 14 and rotatably connected, and four springs 25 respectively connected to the movable blocks 6; the projections of the first rotating rod 13 and the second rotating rod 14 in the vertical plane intersect each other and are symmetrically distributed.

[0019] The end of the spring 25 away from the moving block 6 is respectively set on the upper frame 4 and the lower frame 10. The upper frame 4 and the lower frame 10 are both provided with horizontally distributed guide rods 5. The moving block 6 is slidably connected to the guide rods 5, and the spring 25 is sleeved on the guide rods 5.

[0020] In this embodiment, when the pressure plate 9 presses the textile fabric in the placement groove 2, as the pressure plate 9 descends until it just begins to contact the textile fabric, the extrusion force causes the first rotating rod 13 and the second rotating rod 14 to rotate relative to each other. Consequently, the first connecting piece 7, the second connecting piece 8, the third connecting piece 11, and the fourth connecting piece 12 all push the moving block 6, which is fixedly connected to them, to slide to the side. At the same time, the moving block 6 continuously compresses the spring 25, thereby providing a certain buffering effect on the transmitted extrusion force and preventing the pressure plate 9 from being too high at the moment of contact with the material, which could lead to damage to the textile fabric. Furthermore, the symmetrical structural design of the connecting shaft 15 and the vertical projection of the rotating rod ensures that the pressure plate 9 maintains good stability during the pressing process, avoiding the drawback of uneven force on the lower surface of the pressure plate 9, ensuring the quality of the textile fabric composite processing, and possessing good practicality.

[0021] Example 2, as shown in Figures 1, 3, and 4, presents an adhesive dot transfer laminating machine. Compared to Example 1, in this example, a support frame 16 is provided on the base 1, and a drive mechanism for driving the mounting plate 3 to move vertically is provided on the support frame 16. The drive mechanism includes a motor 17 mounted on the support frame 16, a main shaft 18 driven by the motor 17, a disc 19 coaxially mounted on the main shaft 18, an eccentric shaft 20 mounted on the disc 19, a connecting rod 21 rotatably connected to the eccentric shaft 20, a lifting rod 22 rotatably connected to the connecting rod 21, and a guide assembly mounted on the support frame 16. The main shaft 18 is rotatably mounted on the support frame 16, and the mounting plate 3 is mounted on the lifting rod 22.

[0022] The guide assembly includes two fixed blocks 24 symmetrically distributed on the support frame 16 and two sliders 23 disposed on the lifting rod 22. The fixed blocks 24 are provided with guide grooves for the sliders 23 to slide vertically.

[0023] In this embodiment, when the driving pressure plate 9 presses the textile fabric, the starting motor 17 drives the main shaft 18 to rotate. The main shaft 18 drives the disc 19 and the eccentric shaft 20 to rotate. The eccentric shaft 20 drives one end of the connecting rod 21 to move, while the other end of the connecting rod 21 pulls the lifting rod 22 to move. Due to the guiding effect of the fixed block 24 and the slider 23 on the moving direction of the lifting rod 22, the lifting rod 22 drives the mounting plate 3 to move vertically back and forth, thereby enabling the pressure plate 9 to press the composite fabric multiple times. With the help of the buffer device, the textile fabric is more completely composited, ensuring the firmness of the composite product.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
