Description

Technical Field

[0001] This utility model relates to the field of composite board composite devices, specifically to a coating head for uniform material output. Background Technology

[0002] Coating is a very common industrial processing technology. Simply put, it is a process in which molten plastic (such as polyethylene PE, polypropylene PP, etc.) is evenly coated or bonded to the surface of another substrate (such as paper, cardboard, aluminum foil, plastic film, etc.) using specialized equipment, like "showering," thereby forming a composite material.

[0003] Therefore, uniform material discharge is of paramount importance for coating heads. In existing technologies, coating heads have a discharge channel with an outlet at one end and an inlet at the other. The inlet is connected to a pump or extrusion cylinder. Molten plastic flows into the discharge channel through pump suction or extrusion cylinder compression, and finally flows out from the outlet onto the substrate to be coated. However, after operation stops, residual molten plastic accumulates at the outlet of the coating head. This accumulated plastic reacts with oxygen and other substances in the air to form a hardened substance. When operation resumes the next day or after a period of time, this hardened substance severely affects the uniform material discharge of the coating head. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating head that provides uniform material output.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a coating head for uniform material discharge, comprising: A coating head body, wherein the coating head body has a discharge port; A blockage body, the blockage body being located below the discharge port of the coating head body; The lifting mechanism includes a cylinder with a telescopic rod. The telescopic rod drives the blockage body to rise and fall, thereby allowing the blockage body to selectively close or open the discharge port of the coating head body.

[0006] Preferably, the material used to make the plug is rubber or sponge.

[0007] Preferably, it further includes a base having a mounting groove into which the plug is installed, and at least a portion of the plug extends out of the mounting groove.

[0008] Preferably, the lifting mechanism further includes a lifting plate, which includes a first lifting plate and a second lifting plate. The first lifting plate is connected to the second lifting plate, and the first lifting plate and the second lifting plate are perpendicular to each other. The first lifting plate is installed together with the telescopic rod of the cylinder.

[0009] Preferably, the lifting mechanism further includes a slider, the cylinder is provided with a sliding groove, a sliding rail is provided in the sliding groove, the slider is slidably connected to the sliding rail on one hand, and the slider is installed together with the second lifting plate on the other hand.

[0010] Preferably, the slider is provided with a receiving groove that extends along the length of the slider and is adapted to the sliding track, wherein the sliding track is received in the receiving groove, thereby enabling the slider to slide on the sliding track.

[0011] Preferably, the first lifting plate has a plug-in hole, the telescopic rod of the cylinder is adapted to the plug-in hole, and the telescopic rod is inserted into the plug-in hole, so that the telescopic rod is installed together with the first lifting plate.

[0012] Preferably, it also includes an adapter plate, the base body and the adapter plate are fixedly connected together by bolts or screws, and the first lifting plate is fixedly connected together with the adapter plate by bolts or screws, so that the base body and the lifting plate are connected together.

[0013] The beneficial effects of this application are as follows: The uniformly discharging coating head provided by this application has the advantages of simple structure and easy assembly. The coating head includes a coating head body with a discharge port. A plug is provided, made of a relatively soft material such as rubber or sponge. The plug can selectively open or close the discharge. When the coating device stops working, to prevent the material accumulated at the discharge port from reacting with oxygen in the air to form a hard substance, the plug blocks the discharge port. A lifting mechanism is provided, which drives the plug to rise and fall, thereby opening or closing the discharge port of the coating head body, thus saving manpower. Compared with the prior art, this application can effectively solve the technical problem of uneven discharge caused by the discharge being blocked by hard substances when the coating device starts up.

[0018] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0019] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0020] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0021] Please refer to Figure 1-4 This application provides a uniformly discharging coating head (hereinafter referred to as "the coating head"), the coating head comprising: A coating head body 1, wherein the coating head body 1 has a discharge port 100; Blocking body 2, the blocking body 2 being located below the discharge port 100 of the coating head body 1; The lifting mechanism 5 includes a cylinder 51 with a telescopic rod 510. The telescopic rod 510 drives the blocking body 2 to rise and fall, thereby selectively closing or opening the discharge port 100 of the coating head body 1. After the composite board laminating device stops working, molten plastic or coating material still remains in the discharge port 100 of the coating head body 1. To prevent these materials from reacting with oxygen in the air to form a hard substance, the lifting mechanism 5 drives the blocking body 2 to rise, blocking the discharge port 100. This prevents the molten material at the discharge port 100 from reacting with the air over a large area, ensuring that when coating is needed the next day or longer, the normal and uniform discharge of the coating head body 1 will not be affected.

[0022] In some embodiments of this application, please refer to Figure 1-4 The blockage body 2 is made of rubber or sponge. Rubber or sponge is flexible and elastic, allowing for a better fit with the discharge port 100. Of course, the blockage body 2 can also be made of other materials.

[0023] In some embodiments of this application, please refer to Figure 1-4 The coating head also includes a base 3 with a mounting groove 300. The plug 2 is installed into the mounting groove 300, and at least a portion of the plug 2 extends out of the mounting groove 300. In this application, the plug 2 can be installed into the mounting groove 300 with an interference fit, thereby firmly attaching the plug 2 to the base 3. Of course, to make the connection even stronger, adhesive can be applied to the plug 2 or the mounting groove 300 to bond the plug 2 and the base 3 together.

[0024] In some embodiments of this application, please refer to Figure 1-4 The lifting mechanism 5 further includes a lifting plate 52, which comprises a first lifting plate 521 and a second lifting plate 522. The first lifting plate 521 and the second lifting plate 522 are connected and perpendicular to each other. The first lifting plate 521 is mounted together with the telescopic rod 510 of the cylinder 51. Thus, when the telescopic rod 510 of the cylinder 51 extends or retracts (along the vertical direction), the telescopic rod 510 drives the first lifting plate 521 to rise or fall, and the first lifting plate 521 simultaneously drives the second lifting plate 522 to rise or fall synchronously.

[0025] Please refer to some embodiments of this application. Figure 1-4The lifting mechanism 5 also includes a slider 53. The cylinder 51 has a sliding groove 512, and a sliding rail 511 is provided in the sliding groove 512. The slider 53 is slidably connected to the sliding rail 511 on one hand, and on the other hand, the slider 53 is installed together with the second lifting plate 522. Thus, when the telescopic rod 51 of the cylinder 51 extends and retracts, driving the first lifting plate 521 to rise and fall, to make the lifting and falling more stable, the second lifting plate 522 is installed together with the slider 53. In this way, while the second lifting plate 522 follows the first lifting plate 521 in rising and falling, the slider 53 slides on the sliding rail 511.

[0026] Please refer to some embodiments of this application. Figure 1-4 The slider 53 is provided with a receiving groove 530, which extends along the length of the slider 53 and is adapted to the sliding track 511. The sliding track 511 is accommodated in the receiving groove 530, thereby allowing the slider 53 to slide on the sliding track 511. Of course, this is only one sliding structure; there are other sliding structures as well. For example, the sliding track 511 is provided with a receiving groove, the slider 53 is accommodated in the receiving groove, and the slider 53 can slide in the receiving groove.

[0027] Please refer to some embodiments of this application. Figure 1-4 The first lifting plate 521 has a insertion hole 520. The telescopic rod 510 of the cylinder 51 is adapted to the insertion hole 520 and is inserted into the insertion hole 520, thereby installing the telescopic rod 510 and the first lifting plate 521 together. Of course, the telescopic rod 510 and the insertion hole 520 are connected together by an interference fit.

[0028] Please refer to some embodiments of this application. Figure 1-4 The coating head also includes an adapter plate 4. The base 3 and the adapter plate 4 are fixedly connected together by bolts or screws. The first lifting plate 521 is fixedly connected to the adapter plate 4 by bolts or screws, so that the base 3 and the lifting plate 52 are connected together.

[0029] The uniform discharge coating head provided in this application has the advantages of simple structure and easy assembly. The coating head includes a coating head body with a discharge port. A plug, made of a relatively soft material such as rubber or sponge, is included. The plug can selectively open or close the discharge port. When the coating device stops working, the plug blocks the discharge port to prevent the material accumulated at the discharge port from reacting with oxygen in the air to form a hard substance. A lifting mechanism is provided to drive the plug to rise and fall, thereby opening or closing the discharge port of the coating head body, thus saving manpower. Compared with the prior art, this application effectively solves the technical problem of uneven discharge caused by the discharge being blocked by hard substances when the coating device starts up.
