Abstract
Description
Technical Field
[0001] The utility model relates to the field of heating technology and equipment for metering pumps, in particular to a heating plate for metering pumps. Background Art
[0002] The process of meltblown non-woven fabric is that the polymer particles are heated by a hot melt machine to make the polymer raw materials in a molten state. In actual production, the molten polymer liquid flows out of the hot melt machine and passes through a metering pump before entering the next die head film extrusion process. During this relatively long period of hot polymer liquid transportation, the hot polymer liquid is easy to drop in temperature, thereby affecting the metering accuracy of the metering pump, thereby affecting the accuracy of the automatic control of the entire meltblown equipment, and then affecting the quality of meltblown fiber forming.
[0003] Therefore, in order to ensure that the temperature of the polymer liquid does not drop during the transportation process, the metering pump needs to be heated to ensure that the temperature of the polymer liquid does not drop and the accuracy of the metering is also ensured. However, the existing heating method has the disadvantages of uneven heating, poor sealing, easy heat loss, low heating efficiency, and waste of resources. Utility Model Content
[0004] The utility model aims to overcome the deficiencies of the prior art and provides a metering pump heating plate. The utility model has the advantages of uniform heating, good sealing, low heat loss and high heating efficiency.
[0005] The purpose of the utility model is achieved through the following technical solutions: a metering pump heating plate, comprising a heating plate, the heating plates are arranged in six pieces and are arranged around the periphery of the metering pump, a heat source is arranged inside the heating plate, an insulating plate is fixedly connected to the outside of the heating plate, the six insulating plates are connected by a fixing frame and form an internal hollow cavity, the fixing frame comprises a plurality of angle plates connected to each other at both ends, the angle plates are provided with slots for installing the insulating plates, a honeycomb heat-conducting net is provided on the surface of the heating plate close to the metering pump, and the connection between the angle plates and the angle plates and the connection between the angle plates and the insulating plates are filled with insulating sealant.
[0006] In one preferred embodiment, there are multiple heat sources, and the multiple heat sources are evenly distributed on the heating plate, and the heat sources are all located at the nodes of the honeycomb heat conductive network.
[0007] In one preferred embodiment, a heat conducting plate is fixedly connected to a side of the honeycomb heat conducting network close to the metering pump.
[0008] In one preferred embodiment, the heat conducting plate is made of copper or aluminum.
[0009] The beneficial effects of the utility model are as follows: the utility model is installed in the form of plug-in, and then filled and sealed with insulating sealant, which effectively improves the overall sealing so that there are no gaps, and can greatly reduce heat loss. At the same time, the setting of the insulation board prevents the heat on the side of the heating plate away from the metering pump from being lost, which has a good heating effect on the metering pump and saves resources. The honeycomb heat conductive network is used for heat dissipation to ensure uniform heat dispersion. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0017] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0018] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.
[0019] The terms “first”, “second”, “third”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.
[0020] The terms "parallel", "vertical", etc. do not mean that the components must be absolutely parallel or vertical, but can be slightly tilted. For example, "parallel" only means that its direction is more parallel than "vertical", and does not mean that the structure must be completely parallel, but can be slightly tilted.
[0021] The terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal, vertical or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0022] In addition, the terms "roughly" and "basically" are intended to explain that the relevant content does not require absolute precision, but can have certain deviations. For example, "roughly equal" does not only mean absolute equality. Since it is difficult to achieve absolute "equality" in actual production and operation, there are generally certain deviations. Therefore, in addition to absolute equality, "roughly equal" also includes the above-mentioned situation with certain deviations. Taking this as an example, in other cases, unless otherwise specified, the terms "roughly" and "basically" have similar meanings to the above.
[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" 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 direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The utility model is installed in the form of plug-in, and then filled and sealed with insulation sealant, which effectively improves the overall sealing, so that there is no gap, and can greatly reduce the loss of heat. At the same time, the setting of the insulation plate 3 prevents the heat on the side of the heating plate 1 away from the metering pump 2 from being lost, which has a good heating effect on the metering pump 2 and saves resources.
