Description

Technical Field

[0001] The utility model relates to the technical field of glue coating equipment, in particular to an automatic deviation-correcting coating die. Background Art

[0002] Coating and laminating equipment is widely used for gluing, coating, and laminating substrates such as plastic films, paper, cloth, and leather. Regardless of the type of coating and laminating equipment, the key component is the coating die head. The coating die head has a cavity inside and a glue outlet slot on it for discharging the hot melt adhesive that has entered the cavity for gluing.

[0003] Before coating, polymer coils must be wound around the outer wall of the coating roller and aligned with the edge of the coating die. Improper alignment can cause adhesive leakage from the roller, leading to increased scrap. The existing solution involves adding a web-correcting device before the coating station. While this method ensures alignment between the coating die and the web, the addition of a web-correcting device increases production line length, hindering product appearance control and increasing equipment investment.

[0004] Therefore, the present application proposes an automatic deviation-correcting coating die. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides an automatic deviation-correcting coating die, which solves the problems mentioned in the background art.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] An automatic deviation-correcting coating die comprises a base, vertical plates are symmetrically fixed on the top of the base, and a coating roller is rotatably mounted between the two vertical plates;

[0008] The base is provided with a mounting seat on one side of the two vertical plates, and four slide grooves are provided on the top of the mounting seat in a rectangular array.

A glue outlet is provided on the side of the coating die head close to the coating roller, and a glue inlet pipe connected to the coating die head is fixedly mounted on the side of the coating die head away from the glue outlet. An infrared temperature sensor is fixedly mounted on one end of the coating die head along the axis direction of the coating roller;

[0009] A driving mechanism connected to one of the mounting blocks is installed on the mounting seat, and is used to make the mounting block slide along the sliding groove or stop sliding.

[0010] Furthermore: the driving mechanism includes a threaded rod that is horizontally and rotatably mounted on the mounting seat, one end of the threaded rod extends into the slide groove and is threadedly connected to the mounting block, and a motor for driving the threaded rod to rotate is fixedly mounted on the mounting seat.

[0011] Furthermore: the bottom of the coating die head is fixed with connecting seats in a rectangular array, four connecting seats correspond to four mounting blocks one by one, and the connecting seats and the mounting blocks are fixed by screws.

[0012] Furthermore: a hanging ring is symmetrically fixedly installed on the top of the coating die head.

[0013] Further: the base includes a bottom plate and a supporting mechanism, the supporting mechanism is arranged on the top of the bottom plate, the two vertical plates are located on one side of the supporting mechanism, and the mounting seat is installed on the top of the supporting mechanism.

[0014] Further: the support mechanism includes four telescopic rods, all of which are vertical and fixedly mounted on the top of the base plate. The mounting seat is fixedly mounted on the top of the four telescopic rods. The support mechanism is equipped with an adjustment mechanism that acts on the mounting seat, which is used to make the mounting seat slide or stop sliding along the four telescopic rods.

The model of the infrared temperature sensor 33 is LX-D12, and the infrared temperature sensor 33 is communicatively connected to the PLC host; a driving mechanism 4 connected to one of the mounting blocks 22 is installed on the mounting seat 2, which is used to make the mounting block 22 slide or stop sliding along the slide groove 21, and the driving mechanism 4 is communicatively connected to the PLC host.

[0030] When gluing the sheet, the sheet is wound around the outer wall of the coating roller 51, and the infrared temperature sensor 33 monitors the temperature of the coating roller 51 and the sheet position in front of the coating die 3 in real time, and transmits the detection signal to the PLC host.

One end of the threaded rod 41 extends into the slide groove 21 and is threadedly connected to the mounting block 22. A motor 42 for driving the threaded rod 41 to rotate is fixedly mounted on the mounting base 2. When in use, the motor 42 is controlled to be turned on, and the motor 42 can drive the threaded rod 41 to rotate on the mounting base 2, so that the mounting block 22 can slide in the slide groove 21 for easy control.

[0034] In this embodiment, the bottom of the coating die head 3 is fixed with a connecting seat 34 in a rectangular array, and the four connecting seats 34 correspond to the four mounting blocks 22 one by one, and the connecting seat 34 and the mounting block 22 are fixed by screws. By setting the connecting seat 34 and the mounting block 22 to be fixed by screws, it is convenient to install or disassemble the mounting seat 2.

[0037] In this embodiment, a hanging ring 35 is symmetrically fixedly installed on the top of the coating die head 3. The hanging ring 35 facilitates the hanging of the coating die head 3 and thus facilitates the disassembly of the coating die head 3.

[0038] In this embodiment, the base 1 includes a base plate 11 and a supporting mechanism 12. The supporting mechanism 12 is arranged on the top of the base plate 11, the two vertical plates 5 are located on one side of the supporting mechanism 12, and the mounting seat 2 is installed on the top of the supporting mechanism 12; the supporting mechanism 12 includes four telescopic rods 121 that are all vertical and fixedly mounted on the top of the base plate 11, the mounting seat 2 is fixedly mounted on the top of the four telescopic rods 121, and an adjusting mechanism 122 acting on the mounting seat 2 is installed on the supporting mechanism 12, which is used to make the mounting seat 2 slide or stop sliding along the four telescopic rods 121. By setting the supporting mechanism 12, when the coating die head 3 needs to be inspected, the mounting seat 2 is slid along the four telescopic rods 121 through the adjusting mechanism 122, so that the height position of the coating die head 3 can be adjusted, which is beneficial for the staff to perform inspection and maintenance operations on the coating die head 3.
