Technical Field
[0001] This utility model belongs to the field of hot press technology, specifically relating to an array-type hot press plate for processing composite flooring. Background Technology
[0002] A hot press is a mechanical device that produces composite materials by applying pressure and heat. Its core components are two hot press plates with heating functions. The hot press plates have heating channels or heating pipes inside to transfer heat and pressure. In the processing of composite flooring, the hot press uses the extrusion between the hot press plates to heat and press the material, shaping it into the desired composite flooring. Specifically, multiple layers of prefabricated boards are simultaneously hot-pressed to cure and form composite flooring with a certain width and thickness.
[0003] The heating medium for existing hot press plates is generally steam, heat transfer oil or hot water. One or more meandering pipes of a certain length are machined inside the hot press plate, and steam supply pipes and steam recovery pipes are connected to the two ends of the pipes respectively.
[0004] The disadvantages of this type of hot press plate are as follows: the distance between the outlet and inlet of the heating medium is relatively large, which will generate a certain temperature difference and resistance difference. The longer the flow channel is formed, the more obvious the temperature difference will be, resulting in a large temperature difference across the surface of the hot press plate, which in turn leads to uneven heating of the product. In addition, the pipeline is long and has too many bends, especially multi-channel pipelines, which can easily obstruct the heating medium. The uneven distribution of the medium outlet resistance and inlet resistance affects the heat exchange efficiency and has a great impact on the performance of the composite flooring.
[0005] In summary, considering the processing specifications of existing composite panels, the processing area of existing hot press plates is not large enough. If the processing area of the hot press plate is too large, the heating medium will have to travel too far in the pipes inside the hot press plate, which will lead to slow heating speed and uneven heating effect, resulting in the hot press plate failing to achieve the expected processing effect on large-area composite panels. Utility Model Content
[0006] The purpose of this invention is to solve the problem that the hot pressing effect of existing hot press plates on large-area composite panels fails to meet expectations. Therefore, this invention provides an array-type hot press plate for composite flooring processing.
[0007] To achieve the above objectives, the present invention proposes the following technical solution:
[0008] An array-type hot press plate for processing composite flooring includes several hot press plate units, each hot press plate unit including a hot press plate body and a heating channel;
[0009] The hot press plate body is a rectangular plate structure, and the heating channel is arranged on the horizontal plane inside the hot press plate body;
[0010] The heating channel includes a first main channel, a second main channel, a first branch channel, and a second branch channel, wherein the first main channel and the second main channel extend from one side of the hot press plate body to the other side, respectively.
[0011] The first branch channel is connected to the first main channel in parallel at both ends. The first branch channel extends in a tortuous manner along the direction of the first main channel to form a unidirectional first bypass channel.
[0012] The second diversion channel is connected to the second main channel in parallel at both ends. The second diversion channel extends in a tortuous manner along the direction of the second main channel to form a unidirectional second bypass channel.
[0013] The heating medium flows from one end of the hot press plate body to the opposite end along the first main channel and the second main channel, respectively. The two opposite ends of the hot press plate body where the heating medium flows are defined as the interface side, and the two opposite ends of the hot press plate body adjacent to the interface side are defined as the connection side. The extension directions of the interface side and the connection side are perpendicular to each other.
[0014] Several of the hot press plate units are detachably connected together via the connecting side to form an array of hot press plates arranged on the same horizontal plane and along the extension direction of the interface side.
[0015] Furthermore, the first main channel and the second main channel are arranged alternately and parallel to each other within the hot press plate body, and the first branch channel and the second branch channel are arranged alternately and parallel to each other within the hot press plate body.
[0016] Furthermore, one end of the first main channel extends from one end of the interface side of the hot press plate body, and the other end of the first main channel extends from one end of the other interface side of the hot press plate body; one end of the second main channel extends from the other end of the other interface side of the hot press plate body, and the other end of the second main channel extends from the other end of the interface side of the hot press plate body.
[0017] Furthermore, one end of the first branch channel is led out from a position close to one end of the first main channel, and the other end of the first branch channel is led out from a position close to the other end of the first main channel; one end of the second branch channel is led out from a position close to one end of the second main channel, and the other end of the second branch channel is led out from a position close to the other end of the second main channel.
[0018] Furthermore, the hot press plate also includes a heating channel interface, which is symmetrically arranged on the two interface sides of the hot press plate body. The heating channel interface includes a first interface, a second interface, a third interface, and a fourth interface.
[0019] The first interface is located at one end of the first main channel and is defined as the input port of the first main channel; the second interface is located at the other end of the first main channel and is defined as the output port of the first main channel.
[0020] The third interface is located at one end of the second main channel and is defined as the input port of the second main channel; the fourth interface is located at the other end of the second main channel and is defined as the output port of the second main channel.
[0021] Furthermore, the hot press plate also includes at least one pair of support portions, which are symmetrically arranged on the two interface sides of the hot press plate body and between the two heating channel interfaces on the same interface side of the hot press plate body, respectively located between the first interface and the third interface, and between the second interface and the fourth interface.
[0022] Furthermore, the hot press plate also includes a disassembly assembly, which includes a mounting groove and a mounting component;
[0023] The mounting groove and the mounting component are respectively disposed on the two connecting sides of the hot press plate body, and the extending direction of the mounting groove and the mounting component is parallel to the extending direction of the connecting side.
[0024] The mounting groove corresponds to and matches the mounting component, and is used to connect and fix the two hot press plate units along the connecting side.
[0025] Furthermore, the interior of the connection side where the mounting groove is located and the interior of the mounting component are filled with thermally conductive material.
[0026] Furthermore, the heating channel is a circular flow channel with a circular cross-sectional profile.
[0027] Furthermore, the first main channel and the second main channel have the same inner diameter, and the first branch channel and the second branch channel have the same inner diameter.
[0028] The inner diameters of the first main flow channel and the second main flow channel are less than or equal to the inner diameters of the first branch flow channel and the second branch flow channel.
[0029] Specifically, the heating area of the branch channel is larger than that of the main channel, and it is also easier to lose heat. In order to ensure the heating effect of the branch channel in the central area of the hot press plate, the flow rate of the heating medium entering the main channel from the inlet and then branching into the branch channel is greater than the flow rate in the main channel after branching.
[0030] Furthermore, the first main channel and the second main channel are configured as straight flow channels, and the first branch channel and the second branch channel include straight flow channels and bent flow channels. The diameters of the straight flow channels are kept equal, and the diameters of the bent flow channels are greater than or equal to the diameters of the corresponding connected straight flow channels.
[0031] Specifically, the heating medium enters the bend section from the straight section, and the flow velocity decreases due to turbulence. In order to ensure that the flow velocity of the heating medium in the branch channel is uniform, the flow velocity is appropriately increased by adjusting the orifice diameter of the bend section channel to keep it equal to that of the straight section channel channel, so as to ensure uniform and stable heating effect.
[0032] Furthermore, the inlet and outlet diameters of the first main channel, the second main channel, the first branch channel, and the second branch channel are all larger than the diameters of the corresponding connected straight channel segments.
[0033] The beneficial effects of this utility model are:
[0034] This invention achieves the goal of adjusting the processing size of the hot press plate according to the size of the heated material by designing a hot press plate composed of array units. The detachable array design can be assembled and adjusted according to the processing specifications of existing composite materials. The temperature difference that originally caused heat loss due to the long heating channel caused by the large processing area is greatly reduced. By using hot press plate units to transfer the heating medium, the overall heating efficiency is greatly improved, the temperature difference between the inlet and outlet of the hot press plate unit is reduced, and the problems of slow heating speed and uneven heating effect caused by the large size of the hot press plate are avoided.
[0035] This invention specifically designs the heating channels within the hot press plate body. Specifically, the inlet and outlet ports of the first and second main channels, which are arranged in parallel, are on the same side of the hot press plate body, and their inlets and outlets are opposite. When the heat exchange medium is input into the two main channels, the input port on the same side can provide thermal compensation for the output port, thus avoiding uneven heat distribution at the input and output ports caused by excessively long heating channels, which leads to slow heating and cooling speeds, insufficient uniformity of heating effect, and instability.
[0036] This invention designs two sets of heating channels: a serpentine or "U"-shaped bypass channel is designed on the basis of a main channel. On the one hand, the central area of the hot press plate obtains a uniform heating effect based on the bypass channel; on the other hand, it ensures that the area located at the edge of the hot press plate obtains a uniform heating effect based on the main channel. This controls the temperature difference of the hot press plate body, allowing the composite board to be hot-pressed at a stable and uniform temperature, thereby improving the stability of the hot press plate.
[0037] This invention rationally sets the aperture of the heating channel, specifically enlarging the aperture of the sections in the heating channel design that are prone to heat loss. By increasing the inflow of the heating medium, it compensates for the heat loss caused by the structural design, which leads to uneven heating effect. At the same time, by adjusting the aperture size of different areas in the same flow line, the flow rate of the heating medium in the heating channel is adapted and adjusted, ensuring the stability of the hot press plate processing effect.
