Description

Technical Field

[0001] This utility model relates to a feeding device for a coating machine, and more particularly to a feeding device suitable for a coating machine for high-viscosity adhesive materials. Background Technology

[0002] To produce adhesive sheets from high-viscosity materials at high temperatures, a coating machine is needed to cast and coat the material. After cooling, the resulting sheets are of the required thickness and width. Existing coating machines include a reactor and a feeding device located below the reactor. During the production of the adhesive sheets, the molten adhesive material in the reactor flows into the feeding device below under its own gravity. Subsequently, the adhesive material is discharged from the discharge port of the feeding device onto the conveyor belt on the lower platform, thus forming a continuous coated adhesive sheet.

[0003] However, it is important to know that the material is a high-viscosity adhesive, typically with a viscosity exceeding 100,000 mPa·s. Its flowability is poor in the feeding device, especially its lateral flow rate is slow. The width of the adhesive sheet in this design is usually 2-3 meters. In traditional trough-type feeding systems, after receiving material from the reactor, the high viscosity and poor flowability of the material cause it to spread laterally in a stacking-collapse growth pattern. This means that after the central material accumulates to a certain height, the lateral stress of the accumulation exceeds the yield stress (if the material has a yield stress) or the gravitational component overcomes the viscous resistance, leading to periodic collapse and the formation of a stepped or tongue-shaped front. This growth and spread is slow because the material still needs to spread after falling, and the material replenishment is unstable, resulting in unstable material supply on both sides and frequent material shortages. In other words, during production, there may be a situation where the material supply on both sides of the feeding device cannot keep up with the feeding speed. In this case, the produced rubber sheet will be thinner on both sides than in the center, and its width may not even meet the requirements. There will be problems with unstable width and thickness. When cutting the rubber sheet later, the rubber sheet on both sides is prone to defects, resulting in serious material waste.

[0004] To address this issue, a feeding device suitable for coating machines of high-viscosity adhesive materials was designed to solve the problem of insufficient material supply on both sides in existing feeding devices, thereby producing large-span (2-3 meters) boards with stable quality. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device suitable for coating machines of high-viscosity adhesive materials, so as to solve the problem that existing feeding devices cannot solve the problem of insufficient material supply on both sides when producing wide (2-3 meters) adhesive sheets of high-viscosity materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A feeding device suitable for a coating machine for high-viscosity adhesive materials, comprising:

[0008] End plates, the end plates having two pieces, with a spacing equal to the width of the required adhesive sheet layer to be produced;

[0009] A fixing plate is vertically installed between two end plates and is fixed and sealed to the end plates;

[0010] A top plate is provided at the upper edge of the fixed plate and the end plate, and is sealed to the end plate and the fixed plate. A connecting flange is provided at the middle position of the top plate.

[0011] An adjusting plate is inclinedly disposed between two end plates to form a V-shaped storage trough with the fixed plate. A gap extending along the length of both the adjusting plate and the fixed plate is left at the lower edge to form a discharge port.

[0012] A guide plate is disposed between the adjusting plate and the fixed plate to divide the storage trough formed by the adjusting plate and the fixed plate into several sections. The bottom of the guide plate is concave to form a channel that connects the bottoms of each section. There is a gap between the upper edge of the guide plate and the top plate.

[0013] Preferably, the guide plate is tilted at an adjustable angle in the storage tank, and the guide plate is tilted towards the center, with the tilt angle of the guide plate gradually increasing from the center to both sides so that the channel at the bottom of the guide plate gradually expands from the center to both sides.

[0014] Preferably, the lower part of the adjusting plate has a groove extending along the length of the adjusting plate to divide the adjusting plate into a fixed part and an adjusting part by the groove. The bottom of the groove can be flexibly bent. The end plate is also connected to a flipping mechanism, which is connected to the adjusting part. Rotating the flipping part controls the gap width between the adjusting part and the lower edge of the fixed plate.

[0015] Preferably, the flipping part includes a motor fixedly mounted on the end plate, and a rotating shaft is coaxially connected to the output shaft of the motor. Several levers are evenly distributed along the axial direction on the rotating shaft. The free end of the lever extends to the adjustment part, and an adjustment bolt is screwed onto the free end of the lever, which abuts against the outer surface of the adjustment part.

[0016] Preferably, the adjusting plate is evenly distributed with several support seats, and the rotating shaft is rotatably inserted through the support seats.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: It has been found that when producing wide-width plates from high-viscosity materials, the reason why the material flow rate on both sides of the feeding device cannot keep up with the feeding speed is that the material is a high-viscosity substance. If a traditional feeding device is used, the material flow rate in the storage tank is slow, and it mainly grows in the form of accumulation and collapse. Under this condition, the replenishment of material to both sides is very unstable, which easily leads to the phenomenon that the material supply on both sides cannot keep up with the consumption. The thickness and width of the produced plates often fail to meet the design requirements, and the quality of the plates cannot be guaranteed. This solution, based on the summary, provides the following method: Multiple guide plates are set in the storage tank to divide the storage tank into multiple sections. Simultaneously, an upward-facing groove is opened below the guide plates to create a connecting channel between the bottoms of each section. In this method, after the material enters the partitioned section, due to the presence of the guide plate, regardless of whether the section is overflowing, adjacent sections will inevitably experience compressed lateral flow growth because the bottom channel is located at the lowest level. This growth method is more stable than the accumulation-collapse growth method, and it first replenishes the bottom area of ​​the material trough discharge. That is, the material supply to the two sides of the trough can be directly replenished to the discharge position, avoiding the situation where the material is replenished from top to bottom in the accumulation-collapse method, which may lead to insufficient material supply because the material has entered the two sides but has not fallen into the discharge port in time. Therefore, the structural form in this solution can effectively improve the problem of unstable material supply on both sides when producing wide sheets of high-viscosity materials.

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-3 The feeding device shown is suitable for a coating machine for high-viscosity adhesive materials, including two oppositely arranged end plates 1, the distance between the two end plates being the width of the adhesive sheet to be produced.

[0026] A vertically arranged fixing plate 2 is provided between the two end plates, and the two ends of the fixing plate 2 are fixed and sealed to the end plates.

[0027] Meanwhile, a top plate 3 is also installed on the upper edge of the end plate 1 and the fixing plate 2 by bolts and sealed. The top plate has an opening in the middle and a flange 31 for connecting to the discharge port of the reactor.

[0028] It is important to understand that the aforementioned end plates, fixing plates, and top plates form a semi-enclosed structure, such as... Figure 3As shown, an adjusting plate 4 is also provided between the two end plates. This adjusting plate is inclined, and its lower edge is close to the lower edge of the fixed plate, so as to form a V-shaped material storage groove together with the fixed plate and the end plates. It should be noted that the above structure is a common structure of ordinary feeding devices. When used for feeding high-viscosity materials, due to the flowability of the material, it often leads to material shortages on both sides due to untimely replenishment, and the width dimensions of the sheet on both sides will be difficult to guarantee.

[0029] Therefore, this solution improves upon the previous one through the following technical means. Specifically, multiple guide plates 5 are installed in the storage tank, dividing it into several sections with relatively independent discharge spaces. It should be noted that in this solution, the bottom of the guide plates is concave, creating a channel between the guide plates, the fixed plate 2, and the adjusting plate 4, allowing material in one section to overflow laterally from the bottom channel to adjacent side sections. It should be noted that this direct bottom overflow growth method significantly improves continuity and reliability compared to the accumulation-collapse growth method. Furthermore, it should be noted that the channel in this solution is located at the bottom of the storage tank, i.e., at the discharge port, so the laterally growing material will directly replenish the discharge port, achieving the benefit of immediate use upon replenishment. In addition, it should be noted that in this scheme, there is a gap between the upper edge of the guide plate 5 and the top plate, so that the overflowing material in the section can overflow through the upper cloth of the section. That is, when the material in the middle section is sufficient, the material can also diffuse to both sides through the gap of the upper cloth (in the form of accumulation-collapse growth), realizing material diffusion in two ways and improving the efficiency of material diffusion to both sides.

[0030] It should be noted that in this solution, by creating a channel through an upwardly concave structure at the bottom of the guide plate 5, the material in any section can be transported to the adjacent section through the channel formed by the guide plate 5, the adjusting plate 4, and the fixing plate 2, regardless of whether the material height in any section is greater than that in the adjacent section (it is likely that the closer to the middle, the higher the material height and the larger the material storage capacity). This allows for rapid replenishment of consumed material in the two side sections from the bottom, avoiding the problem of insufficient material replenishment in the two side sections. Using the structural form of this solution, it is not necessary to fill all sections when replenishing material to the sides, thus overcoming the problems existing in traditional feeding devices.

[0031] Furthermore, it should be noted that in this design, to improve the efficiency of supplying materials to the two side sections, the guide vane 5 is designed with an adjustable tilt angle. Specifically, the guide vanes tilt towards the center, with the tilt angle increasing from the center to the side components. This causes the bottom channel of the guide vane to gradually increase from the central area to both sides, thereby improving the ability of the side sections to receive materials through the bottom channel. Additionally, it should be noted that the guide vanes in this design are fixed to the adjustment plate with bolts. When the tilt angle of the guide vane needs to be adjusted, simply loosen the bolts; after the tilt angle is adjusted, retighten the bolts to ensure the stability of the guide vane during operation.

[0032] It should also be noted that the thickness requirements for sheets of different specifications vary during the fabrication of the adhesive sheet layer. Therefore, the feeding device in this solution needs to have a thickness adjustment function. Specifically, the adjusting plate 4 in this solution has a groove 41 extending along its length, dividing it into two parts: an upper fixed part 42 and a lower adjusting part 43. A gap exists between the lower edge of the adjusting part and the fixed plate to form a feeding opening. It should be noted that the thickness of the adjusting plate 4 at the location of the groove 41 decreases, thus reducing its yield strength. This allows for adjustment of the adjusting part; when force is applied to the adjusting part, the bottom of the groove 41 can elastically bend, thereby flexibly controlling the gap (feeding opening width) between the adjusting part and the fixed plate, achieving flexible adjustment of the feeding opening width. It should be understood that in this solution, a set of reversing mechanisms 6 can apply a corresponding force to the adjusting part 43.

[0033] Specifically, the flipping mechanism 6 in this solution includes a motor 61 fixedly mounted on the end plate 1. A rotating shaft 62 is coaxially connected to the output shaft of the motor, and several levers 63 are evenly distributed along the axial direction of the rotating shaft. It should be noted that the free end of each lever 63 extends to the adjusting part 43, and an adjusting bolt 64 is screwed onto the free end of the lever. This adjusting bolt abuts against the adjusting part to apply force to it. When it is necessary to reduce the width of the discharge port, the adjusting bolt is screwed in towards the adjusting part 43, so that the adjusting bolt applies an inward pushing force to the adjusting part. When it is necessary to widen the width of the discharge port, the adjusting bolt is simply screwed in the opposite direction, so that the adjusting part 43 is reset by the self-rebound of the bottom of the groove 41.

[0034] It should be noted that the multiple levers applied in this solution enable each area of ​​the adjustment section to have independent adjustment capabilities. That is, if the thickness of a local area is unreasonable during the production process, the width of the discharge port in that local area can be finely adjusted by adjusting the adjusting bolt 64 of the corresponding area.

[0035] It is also important to know that because the sheet material produced by this solution is relatively wide, the length of the rotating shaft must also be adapted to it. If a single rotating shaft is suspended in the air, it will inevitably exert force on the adjustment part and bend itself due to the reaction force. To ensure the stability and straightness of the rotating shaft, several support seats 65 are installed on the fixed part. The rotating shaft can rotate through the support seats 65, so that there is a fulcrum for support every time the rotating shaft extends a certain distance, thus preventing it from bending.

[0036] Working Principle: This solution divides the material storage tank into multiple sections using guide plates, with the bottoms of each section connected by channels. The high-viscosity material within these sections will have its lateral growth pattern altered due to these interconnected channels. The original accumulation-collapse growth pattern will be changed to a pattern primarily characterized by bottom lateral overflow growth, supplemented by top accumulation-collapse growth. Therefore, as long as the material in one section is higher than that in adjacent sections, due to the principle of communicating vessels, the high-viscosity material will not need to fill its current section (a prerequisite for accumulation-collapse growth) to overflow from the bottom into sections with less material. Furthermore, this overflow replenishment method is bottom-level (near the discharge port), allowing for rapid replenishment to the discharge ports of both sides, thus ensuring stable output from both sides and preventing unstable sheet widths during production.

[0037] It should be noted that, yes, when high-viscosity substances...
