However, the upper and lower spacing of the hot plate in the hot press main machine cannot be adjusted. For thinner plates, the spacing between the hot plate is too large, not only failing to increase the number of plates processed at the same time, but also the large gap will cause more heat loss and waste.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the utility model and the accompanying drawings to further describe the technical solution of the utility model, but the utility model is not limited to these embodiments.

[0025] Example 1

[0026] like Figures 1-4 As shown, the multi-layer hot pressing drying equipment includes a drying rack 1, an overhead drying section is provided in the drying rack 1, a lifting platform 11 is provided on the lower side of the drying section, and a plurality of stacked hot plates 2 are provided above the lifting platform 11. The drying rack 1 is also provided with a spacing adjustment component 3, and both ends of each hot plate 2 are mounted on the spacing adjustment component 3, and a uniform gap is left between each layer of hot plates 2.

[0027] That is, a spacing adjustment component 3 is added to the drying rack 1, and the spacing adjustment component 3 is used to hook the hot plates 2 of each layer, so that different gap distances are generated between the hot plates 2. The gap is narrowed and more hot plates 2 are added to reduce heat loss, and the gap is increased to adapt to thicker plates, so that the drying rack 1 can improve the applicability of the frame while maintaining energy utilization.

[0028] In this embodiment, the spacing adjustment assembly 3 includes an adjusting swing arm 31 and an adjusting cylinder 32. One end of the adjusting swing arm 31 is rotatably connected to the upper side of the drying rack 1. The adjusting cylinder 32 is connected to the adjusting swing arm 31 with the drying rack 1 as a fulcrum, and the hot plate 2 is mounted on the adjusting swing arm 31.

[0029] Spacing adjustment components 3 are provided at the four corners of the hot plate 2. The upper end of the adjusting swing arm 31 is connected to the drying rack 1 by a rotating shaft, so that the adjusting swing arm 31 swings in the long side direction of the hot plate 2. The adjusting cylinder 32 is connected to the arm body of the adjusting swing arm 31. By adjusting the extension and contraction of the cylinder 32, the swing angle of the swing arm is controlled to determine whether the hot plate 2 needs to be supported.

[0030] In this embodiment, a step block group is provided on the adjusting swing arm 31 , and the step block group includes a plurality of step blocks 33 arranged at different heights, and each heating plate 2 is mounted on the step block 33 at the corresponding height.

[0031] Several step blocks 33 at different heights are distributed on the side of the adjusting swing arm 31 close to the hot plate 2. The step blocks 33 of the same height in the adjusting swing arm 31 at the four corners support the hot plates 2 at the corresponding height, and the upper and lower heights of adjacent step blocks 33 are also kept consistent, so that the hot plates 2 have a uniform spacing.

[0032] In this embodiment, a laterally protruding overlap block 21 is provided on the side of the hot plate 2 close to the adjusting swing arm 31. The overlap block 21 abuts against the step block 33 of the corresponding height, and the overlap block 21 does not contact other step blocks 33 in the step block group.

[0033] The hot plate 2 has an outwardly protruding overlap block 21 that only contacts the step block 33, and the step blocks 33 are distributed without overlapping in the upper and lower directions, ensuring that the hot plate 2 can be placed on the spacing adjustment component 3 by relying on the overlap block 21, but will not be blocked by other step blocks 33 when the lifting platform 11 pushes it up, and can return to its corresponding step block 33 when the lifting platform 11 descends.

[0034] Preferably, at least two step block groups are provided on the adjusting swing arm 31 , and each step block group is arranged on the adjusting swing arm 31 in the direction of the adjusting swing arm 31 .

[0035] Since the non-overlapping distribution of the step blocks 33 in a step block group in the up and down directions requires the adjustment swing arm 31 to have a certain width, but it is obvious that the adjustment swing arm 31 is not suitable for a swing arm that is too wide. Therefore, multiple step block groups are set based on the distribution order of the step blocks 33 in a step block group to increase the number of settings of the hot plate 2.

[0036] Among them, it is necessary to adapt and adjust the distance between the top plate 13 and the uppermost hot plate 2 and the rising amplitude of the lifting platform 11 to avoid the situation where the topmost hot plate 2 has not yet contacted the top plate 13, and the overlapping block 21 has already abutted against the step block 33 at the same position in the upper step block group, thereby preventing the hot pressing process between the hot plate 2 and the top plate 13.

[0037] In this embodiment, the drying rack 1 includes side panels 12 and a top panel 13 . The top panel 13 is connected to the tops of the two side panels 12 . The drying section is arranged between the top panel 13 and the lifting platform 11 . The sides of the hot plate 2 are against the two side panels 12 .

[0038] The side panels 12 and the top panel 13 are combined into a hollow frame structure. The hot plate 2 is placed in the hollow drying section. The two sides of the hot plate 2 are against the side panels 12 to limit the position of the hot plate 2. The plates placed between the hot plates 2 are pushed toward the top panel 13 by the lifting platform 11 on the lower side for extrusion.

[0039] In this embodiment, a hanging angle 22 is provided on the side surface of the hot plate 2 that abuts against the side plate 12 , and the hanging angle 22 semi-encloses and abuts against the side plate 12 .

[0040] In addition to the two side edges of the hot plate 2 being abutted against the side panels 12 for limiting position, hanging angles 22 are also installed on the same side. The hanging angles 22 on one side have two protrusions with a spacing just equal to the width of the side panels 12, forming abutment against the three surfaces of the side panels 12, so that the position of the hot plate 2 on the horizontal plane is fixed, and the step block 33 and the corresponding overlap block 21 can be accurately overlapped to support the hot plate 22, and the hot plate 22 slides on the two side panels 12 as a track when rising.

[0041] Preferably, a stair tread 14 is provided on the side panel 12 , and each hanging angle 22 rests against the step surface of the corresponding stair tread 14 .

[0042] Usually, the height difference between the step surfaces of the stair plate 14 is greater than the height difference between the step blocks 33. During the descending stage after hot pressing, the adjusting cylinder 32 can be adjusted to expand the adjusting swing arm 31 outward to allow the hot plate 2 to descend to the stair plate 14 on the lower side. The stair plate 14 also divides the gaps between the hot plates 2 into layers, but the spacing will be greater than the spacing of the spacing adjustment component 3, so that the hot pressed plates can be taken out more easily.

[0043] Of course, for thicker plates, the large spacing between the stair treads 14 can be directly utilized for loading and hot pressing.

[0044] In this embodiment, heat source access holes are provided on both sides of the heat plate 2 where the heat plate 2 abuts against the side plate 12 , and avoidance grooves are provided on the side plate 12 to expose the heat source access holes.

[0045] The side panels 12 are provided with large avoidance slots, through which the lines or pipes of the heat source pass and are connected to the access holes, and will not be blocked when the hot plate 2 moves up and down.

[0046] In this embodiment, fixedly connected extrusion plates are provided on the bottom of the top plate 13 and the surface of the lifting platform 11 , and the extrusion plates are in contact with the hot plate 2 .

[0047] The extrusion plate installed on the top plate 13 is a plate made of the same material as the hot plate 2, and is used to contact the plate placed on the uppermost hot plate 2 during hot pressing. The extrusion plate set on the lower side on the table top of the lifting platform 11 will contact the lowermost hot plate 2. In order to prevent the table top from damaging the hot plate 2, a plate made of the same material as the hot plate 2 is also used.

[0048] Example 2

[0049] On the basis of the technical solution of Example 1, the spacing adjustment components 3 on the four corners are used as a control group, and multiple groups of controllable spacing adjustment components 3 are added. The step blocks 33 in each group of spacing adjustment components 3 have upper and lower spacings of each group. Each time, a group with a suitable spacing is used according to the thickness of the plate, and the other spacing adjustment components 3 are expanded outward, so that the hot pressing process of plates of various specifications can be performed on the same drying rack 1, and heat loss can be reduced and energy utilization can be improved.

[0050] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
