Description

Technical Field

[0001] The present application relates to the field of fiberboard processing equipment, and specifically to a fiber microwave heating device for fiberboard production. Background Art

[0002] During the production process, fiberboard needs to be heated and dried to remove moisture, thereby reducing the water absorption rate of the fibers and improving the fiber bonding strength of the product. However, the current heating method usually involves placing the fiberboard in a dryer for heating, which has low heating efficiency and is relatively labor-intensive.

[0003] Application No. 202222526705.X ​​discloses an environmentally friendly fiber microwave heating device for the production of medium-density fiberboard, including a gantry, a heating element, a vertical plate, an opening, a placement plate, a flipping element, a dust removal element and a telescopic cylinder. The utility model adds a clamping flipping element and a heating element to the device to flip the medium-density fiberboard, which is convenient for drying the other side of the medium-density fiberboard. There is no need for manual flipping. The heating element is used to dry the upper and lower surfaces of the medium-density fiberboard respectively, ensuring that the medium-density fiberboard is dried more evenly, avoiding moisture residue in the medium-density fiberboard, and improving the quality of medium-density fiberboard processing; through the action of the dust removal element, the dust generated during the drying process is sucked into the interior of the collection box to prevent the dust from drifting into the working environment, which is beneficial to environmental protection and personnel health; the utility model has a simple structure and is easy to operate, which can effectively save manpower and material resources and improve work efficiency.

[0004] However, in use, there are the following defects:

[0005] Since the device turns the MDF board over by providing a flipping piece so that the other side can be dried and heated, flipping usually requires a large space to achieve, and the flipping space is also proportional to the size of the MDF board. When encountering a large MDF board, flipping becomes inconvenient, thereby affecting the heating of the other side. At the same time, the device only has a heating lamp on the top for heating, and the heating efficiency is low, affecting the practicality of the device. Utility Model Content

[0006] The purpose of the present application is to provide a fiber microwave heating device for fiberboard production, which solves the problem raised in the background technology that the device turns over the medium-density fiberboard by setting a flipping piece so that the other side can be dried and heated, and the flipping usually requires a larger space to achieve, and the flipping space is also proportional to the size of the medium-density fiberboard. When encountering a large medium-density fiberboard, flipping becomes inconvenient, thereby affecting the heating of the other side. At the same time, the device only has a heating lamp on the top for heating, and the heating efficiency is low, affecting the practicality of the device.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a fiber microwave heating device for fiberboard production, comprising a box body, an upper slider, a lower slider, a fixed frame, an air outlet and a groove, a bottom slide groove is horizontally provided at the bottom inner side of the box body, and a top slide groove is horizontally provided at the top inner side of the box body, the lower slide groove is connected to the box body for horizontal sliding through the bottom slide groove, the upper slide groove is connected to the box body for horizontal sliding through the top slide groove, a limiting rod is fixedly connected between the upper slide and the lower slide groove, a groove is provided in the center of the side wall of the limiting rod, a lower electric telescopic cylinder is fixedly installed on the inner bottom of the box body between the bottom slide grooves, and an upper electric telescopic cylinder is fixedly installed on the inner top of the box body between the top slide grooves, a lower support plate is fixedly installed on the top of the lower electric telescopic cylinder, and an upper support plate is fixedly installed on the bottom of the upper electric telescopic cylinder.

[0008] In this technical solution, through the bottom slide, top slide, limit rod and groove, fiberboards of different sizes and widths can be accommodated to slide in, the lateral positions of the lower slider and the upper slider are adjusted according to the size of the fiberboard, and the lower slider is fixed by fixing bolts. The two sides of the fiberboard slide in by the grooves, and the placement frame can support the central position of the fiberboard to prevent the fiberboard from being concave due to force. Since it can adapt to fiberboards of various sizes, the practicality of the device is improved. Through the lower support plate, lower heating lamp, upper support plate and upper heating lamp, both sides of the fiberboard can be heated at the same time, so there is no need to heat a single side of the fiberboard and then flip it to heat the other side, which reduces the operation steps, saves the space of the device and improves the heating efficiency of the device. At the same time, through the No. 1 telescopic motor, the lower electric telescopic cylinder, the No. 2 telescopic motor and the upper electric telescopic cylinder, the distance between the upper heating lamp and the lower heating lamp can be adjusted to make the surface of the fiberboard closer to the heat source, thereby drying faster and improving the drying efficiency of the device. After drying is completed, the fiberboard can be pulled out from the placement frame and the groove.

[0009] As an optional solution of the technical solution of the present application, a lower heating lamp is fixedly installed on the top of the lower support plate, and an upper heating lamp is fixedly installed on the bottom of the upper support plate.

[0013] As an optional solution of the technical solution of the present application, a fixing bolt is movably provided at the top end of the lower sliding block (201) on one side of the limiting rod.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The present application uses a lower support plate, a lower heating lamp, an upper support plate and an upper heating lamp to heat both sides of the fiberboard simultaneously, thereby eliminating the need to heat a single side of the fiberboard and then flip it over to heat the other side. This reduces the number of operating steps, saves space in the device, and improves the heating efficiency of the device.

[0016] 2. This application uses the No. 1 telescopic motor, the lower electric telescopic cylinder, the No. 2 telescopic motor and the upper electric telescopic cylinder to adjust the distance between the upper heating lamp tube and the lower heating lamp tube, so that the surface of the fiberboard is closer to the heat source, thereby drying faster and improving the drying efficiency of the device.
