Description

Technical Field

[0001] The utility model relates to the technical field of prepreg heating, in particular to a melt grate. Background Art

[0002] In the processing of resin materials, grates are important auxiliary tools, and their design plays a key role in improving production efficiency, optimizing product quality and reducing production costs. Traditional melt grates are mostly designed with cylindrical or flat shapes, but there are many shortcomings in practical applications. For example, the circular grates drip slowly after the resin melts, and due to shape restrictions, it is difficult to fix a protective film on the outer wall of the grates, resulting in difficult and inefficient cleaning. Although flat grates solve the cleaning problem to a certain extent, the large contact area and uneven pressure distribution result in a slow melting of the resin.

[0003] Therefore, it is urgent to develop a novel grate, aiming at solving the problems in the prior art. Summary of the invention

[0004] The utility model aims at the shortcomings and deficiencies in the prior art and provides a melt grate with an ingenious design in which the grate bars are arranged as a triangular prism structure, which not only improves the melting efficiency and production efficiency of the resin, but also simplifies the cleaning work, reduces the production cost, improves the processing efficiency, and prolongs the service life of the melt grate.

[0005] To achieve the above purpose, the utility model is implemented by the following technical scheme: comprising a grate body, the grate body comprising a transversely arranged external frame, a plurality of parallelly arranged grate bars are arranged at intervals on the external frame, each grate bar is a steel pipe of a triangular prism structure, two bottom edge edges of the triangular prism are arranged at the bottom of the external frame and are located in the same plane; the edge corresponding to the vertex angle of the triangular prism is arranged at the top of the external frame;

[0006] The external frame and the grate bars are heating tubes with heating function, and a thermocouple is arranged at one end of the heating tube.

[0007] Preferably, the entire molten glue grate is made of a material having thermal conductivity, and the thermal conductive material is stainless steel.

[0008] Preferably, the external frame is a rectangular frame consisting of two long connecting rods and two short connecting rods connecting the two long connecting rods, both ends of the long connecting rod are longer than the connection between the two ends of the long connecting rod and the short connecting rod, and the two ends of the grate bar are respectively welded to the inner side surfaces of the two short connecting rods;

[0009] The short connecting rod, the grate bar and the long connecting rod are internally connected with each other through pipes, and the ends of the two long connecting rods on the same side are respectively a liquid inlet and a liquid outlet.

[0010] Preferably, the short connecting rod and the long connecting rod are both square tubes, the top edge of the grate triangular prism structure is flush with the upper surface of the short connecting rod, and the two bottom edges of the grate triangular prism structure are flush with the lower surface of the short connecting rod.

[0011] Preferably, a plurality of parallel grate bars are evenly spaced and arranged on the external frame, and a gap between the bottom planes of two adjacent grate bars is ≥10 mm.

[0012] Preferably, the two side surfaces of the grate triangular prism structure are smooth and an easy-to-clean isolation layer is provided on the surface.

[0013] The utility model provides a melt-melting grate, which has the following beneficial effects:

[0014] (1) The melt grate of the utility model has an ingenious structural design. Its grate bars are designed as triangular prism structures, so that when the resin material is in a solid state, the contact point with the grate bars is relatively small, and thus the pressure is relatively large, so that the resin at the contact point can be quickly melted, resulting in a cutting effect on the resin material, thereby improving the melting efficiency of the resin.

[0015] (2) The melt grate of the utility model has a triangular prism structure with an inclined surface design. Since heat is quickly transferred along the edges of the triangle, the resin can quickly fall along these edges, so that the melted resin can be heated evenly and quickly. Compared with traditional round grates, the dripping time is greatly shortened, thereby improving production efficiency.

[0016] (3) Compared with flat or arc-shaped grates, the triangular prism structure of the melt-adhesive grate of the utility model makes cleaning easier. A folded upper surface is formed between the outer surfaces of a plurality of parallel grates, and a replaceable protective film can be folded and placed directly on the grates. At regular intervals, the protective film can simply be removed and replaced with a new one, which greatly saves the use of cleaning solvents, reduces the labor intensity of manual cleaning, and prolongs the service life of the grates.

[0017] In addition, compared with traditional round grates, due to the design of triangular grates, the protective film can be firmly fixed on the grates and will not enter the glue tank with the dripping resin, thus avoiding production problems caused by the falling off of the protective film.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The utility model provides a technical solution:

[0024] like Figure 1-Figure 2 As shown, the melt grate of the utility model includes a grate body, which includes a transversely arranged external frame, and a plurality of parallelly arranged grate bars 3 are arranged at intervals on the external frame, and each grate bar 3 is a steel pipe of a triangular prism structure, and the two bottom edges of the triangular prism are arranged at the bottom of the external frame and are located in the same plane; the edges corresponding to the top angles of the triangular prism are arranged at the top of the external frame; the external frame and the grate bars 3 are heating tubes with heating function, and a thermocouple is arranged at one end of the heating tube. When the melt needs to be heated, the required heating temperature can be set by controlling the thermocouple at one end of the heating tube. Once the heating function is started, the external frame and grate bars 3 of the melt grate will start to heat and maintain the set temperature.

[0025] The above structure is cleverly designed, and the grate bar 3 is a triangular prism structure design, so that when the resin material is in a solid state, the contact point with the grate bar 3 is relatively small, so the pressure is relatively large. This design allows the resin at the contact point to melt quickly, has a cutting effect on the resin material, and improves the melting efficiency of the resin. At the same time, the inclined surface design of the triangular prism steel pipe structure of the grate bar 3, due to the rapid transfer of heat along the edges of the triangle, the resin can fall quickly along these edges, so that the melted resin can be heated evenly and quickly. Compared with the traditional circular grate bar, the dripping time is greatly shortened, and the production efficiency is improved. In this structural design, compared with the plane or arc-shaped grate bar 3, the triangular structure makes cleaning easier. A folded upper surface is formed between the outer surfaces of several parallel grate bars 3, and a replaceable protective film can be folded and placed directly on the grate bar 3. Every once in a while, you only need to simply remove the protective film and replace it with a new one, which greatly saves the use of cleaning solvent and reduces the labor intensity of manual cleaning. In addition, due to the design of the triangular grate bars 3, compared with the traditional circular grate bars, the protective film can be firmly fixed on the grate bars 3 and will not enter the glue tank together with the dripping resin, thereby avoiding production problems caused by the falling off of the protective film, ensuring the stability and continuity of the production process, improving production efficiency, and extending the service life of the grate bars 3.

[0026] The external frame is a rectangular frame consisting of two long connecting rods 1 and two short connecting rods 2 connecting the two. Both ends of the long connecting rod 1 are longer than the connection between the two ends of the long connecting rod 1 and the short connecting rod 2. The two ends of the grate bar 3 are respectively welded on the inner side surfaces of the two short connecting rods 2. The short connecting rod 2, the grate bar 3 and the long connecting rod 1 are interconnected pipes. The ends on the same side of the two long connecting rods 1 are respectively the liquid inlet 4 and the liquid outlet 5. When the melt grate is in use, the liquid flows into the grate body from the liquid inlet 4 and flows out from the liquid outlet 3. The short connecting rod 2 and the long connecting rod 1 are both square tubes. The top edge of the triangular prism structure of the grate bar 3 is flush with the upper surface of the short connecting rod 2, and the two bottom edges of the triangular prism structure of the grate bar 3 are flush with the lower surface of the short connecting rod 2. A number of parallel grate bars 3 are evenly distributed on the external frame, and the gap between the bottom planes of two adjacent grate bars 3 is ≥10mm. This structural design further limits the installation and connection position of the grate bars 3. The melt-glue grate improves the structural stability, support uniformity, and cleaning and maintenance convenience of the melt-glue grate through reasonable structural layout and gap setting of the grate bars 3, so that the melt-glue grate can better meet actual application needs.

[0027] The whole melt grate is made of a material with thermal conductivity, and the thermal conductive material is stainless steel. This material setting can quickly reach the preset temperature, thereby improving work efficiency.

[0028] The two side surfaces of the triangular prism structure of the grate bar 3 are smooth and provided with an easy-to-clean isolation layer, which not only helps to improve the efficiency of the melt glue processing and reduce the cleaning difficulty and cost, but also can extend the service life of the grate bar 3, bringing improvements and enhancements to the melt glue processing process.

[0029] The usage process is as follows:

[0030] First, the operator sets the required heating temperature of the melt grate by controlling the thermocouple. Once the temperature is set, the outer frame and grate bars of the melt grate will begin to heat up and gradually reach and maintain the set temperature.

[0031] Next, the operator will place a replaceable protective film on the folded upper surface formed between the outer surfaces of the grate bars 3 of the melt grate to ensure that during subsequent operations, the resin material will not directly contact the grate bars 3, thereby keeping the grate bars 3 clean and extending their service life.

[0032] Afterwards, the operator will pour the solid resin material onto the melt grate. Since the grate bar 3 adopts a triangular prism structure design, when the resin material is in a solid state, the contact point with the grate bar 3 is relatively small, so the pressure is relatively large, so that the resin at the contact point can be quickly melted and have a cutting effect on the resin material; this design improves the melting efficiency of the resin, making the whole process faster and more efficient. At the same time, during the heating process, the heat will be quickly transferred along the edge of the triangle, so that the resin can fall quickly along the edge, ensuring that the melted resin can be heated evenly and quickly, thereby shortening the falling time and improving production efficiency.

[0033] Secondly, during the melting process, the protective film can be firmly fixed on the grate bar 3 and will not enter the glue tank together with the dripping resin, thus avoiding production problems caused by the shedding of the protective film and ensuring the stability and continuity of the production process.

[0034] When the production process is finished, the operator only needs to simply remove the protective film on the grate bar 3 and replace it with a new one. This step not only greatly saves the amount of cleaning solvent used, but also reduces the labor intensity of manual cleaning, making the entire production process more convenient and efficient.

[0035] In summary, the melt-bonding grate of the utility model, by configuring the grate bars to be a triangular prism structure, not only improves the melting efficiency and production efficiency of the resin, but also simplifies the cleaning work, reduces the production cost, and prolongs the service life of the melt-bonding grate.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme of the present invention and the concept of the present invention, which should be covered by the protection scope of the present invention.
