Description

Technical Field

[0001] The utility model relates to the field of sheet material placement racks, in particular to a sheet material drying rack mechanism. Background Art

[0002] The raw material of hot-pressed multi-layer boards is thin wood sheets. Before hot pressing, the sheets need to be processed through multiple processes, including gluing and air-drying the surface of the sheets. During the static drying, each thin sheet must be flat and cannot be disturbed by other sheets or debris. Otherwise, the glue on the surface may be uneven or contaminated with foreign matter, resulting in bubbling, pollution, adhesion of debris, uneven hot pressing, color spots and other problems during hot pressing. However, due to the large number of sheets and the large area, there is not enough space in the workshop to provide conditions for single-sheet display, which not only affects the processing efficiency and leads to low efficiency of drying, but also the overlapping or scratching of sheets will cause the above problems.

[0024] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0025] Example:

[0026] The base frame 1 is a rectangular frame structure, and casters are installed at the four corners to facilitate the transfer of the entire rack. The rack can be pushed into a separate room for drying the slices according to conditions, thereby avoiding the interference of dust and impurities.

[0027] One side of the base frame 1 is provided with two upright angle irons extending upward. The upright angle irons are cut from right-angle profiles and welded to the corner ends of the base frame 1. The upright angle irons include side panels 2 and rear panels 3 connected at right angles. The side panels 2 and rear panels 3 are both upright long strips. The side panels 2 are vertically connected to the vertical sides of the rear panel 3, and the internal angles are set outside, so that the two side panels 2 are parallel and the two rear panels 3 are coplanar.

[0028] A plurality of layers of shelves are arranged in sequence along the height direction above the base frame 1. The shelves adopt a metal grid structure and are rectangular as a whole, including a rectangular frame 4. One side of the rectangular frame 4 is a mounting frame rod 5, and the side of the rectangular frame 4 opposite to the mounting frame rod 5 is a front frame rod 6. The other two sides of the rectangular frame 4 that are vertically connected to the mounting frame rod 5 are frame rods 7. Both ends of the mounting frame rod 5 are respectively provided with mounting shafts 8, and the mounting shafts 8 pass through the side panels 2 on the same side and are rotatably connected to the side panels 2, so that the shelves can be flipped between two direct angle irons. A mounting screw 9 is passed through the rear panel 3 at the same height as each mounting shaft 8, and a nut member is matched on the mounting screw 9, and the mounting screw 9 and the rear panel 3 are installed by the nut member. One end of the mounting screw 9 located at the inner corner of the upright angle iron is provided with a hinged joint 10 fixedly connected thereto, and a hanging hole 11 is passed through the hinged joint 10.

[0029] A hanging ring 13 extending outward is provided on the frame rod 7 of the rectangular frame 4 near the mounting frame rod 5, and a tension spring 12 is provided between the hanging ring 13 and the hanging hole 11. The two ends of the tension spring 12 are respectively hooked on the hanging ring 13 and the hanging hole 11. When the layer board is flat, the tension spring 12 helps the layer board to remain flat and stable. When the layer shelf is lifted (such as Figure 1 The tension spring 12 can keep the shelves in an upward state, thereby facilitating the operation of the shelves below.

[0030] A horizontal bar 14 and a vertical bar 15 parallel to the side of the rectangular frame 4 are fixed therein, and the vertical bar 15 and the horizontal bar 14 are vertically staggered to form a tic-tac-toe mesh structure, with large meshes and excellent ventilation effect. The length direction of the horizontal bar 14 is in the same direction as the mounting frame bar 5, and the vertical bar 15 is in the same direction as the frame bar 7.

[0031] A plurality of support angles 16 are installed on the side of the front frame rod 6, and the support angles 16 are metal bent plates bent by sheet metal. The support plates are correspondingly installed at the corner ends of the rectangular frame 4 - the intersection of the front frame rod 6 and the frame rod 7, or the intersection of the front frame rod 6 and the longitudinal rod 15. The support angles 16 include an upper plate 17 and a lower plate 18, and a 180 degree bend is arranged between the upper plate 17 and the lower plate 18. The upper plate 17 is arranged above the frame rod 7 or above the longitudinal rod 15, and the lower plate 18 is located below the frame rod 7 or the longitudinal rod 15. The intersection position is used to obtain better support. Screws can be passed through between the upper plate 17 and the lower plate 18, and the screws can be passed through the corresponding frame rod 7 or the longitudinal rod 15 or the front frame rod 6 at the same time, so as to achieve fixation with the front side of the shelf. The lower plate 18 has a downwardly bent triangular shape, and based on the triangular bend 19, point support with the sheet material of the lower layer is achieved, reducing the contact area, so that each layer of the shelf can be flat and reliably supported.

[0032] Since the sizes of the sheets are not uniform, if only the layer rack is used, the outer side of the sheet will droop downward when encountering a larger sheet, causing deformation, contact and scratching with the lower layer, etc. Therefore, an extension rack is also provided to cooperate with the layer rack, and the extension rack includes hanging rods 20 arranged in parallel on both sides, and multiple connecting rods 21 are provided between the two hanging rods 20 to connect the two, and a hook 22 bent downward is provided at one end of the hanging rod 20, and the hook 22 is hooked with the cross bar 14, and a support groove 23 is provided on the bottom side of the hanging rod 20, and the spacing of the support groove 23 is adapted to the spacing of the cross bar 14, which is used for auxiliary support and position limiting on the cross bar 14. The minimum distance between the two hanging rods 20 can be set to be adapted to the maximum distance between the two outermost longitudinal rods 15, and can be hooked outside the two outermost longitudinal rods 15, and constrained by the longitudinal rods 15 to be supported in the center on the layer rack.

[0033] The extension frame is flexible to use. The extension frame is held in hand so that the hook 22 is inserted downwardly into a corresponding cross bar 14, and the extension frame is flattened so that it falls on the shelf. When a large support surface is required for the sheet, the hook 22 is hooked on the cross bar 14 of the front frame as much as possible. If the support surface that needs to be extended outward is small, it can be hooked inside. The extended range is flexible and easy to change, and it is very easy to operate.

[0034] By using this layer rack, sheets can be placed one by one on different layers to achieve independent single-layer drying of sheets. The multi-layer rack can realize space utilization, which can not only ensure independent supporting space for sheets, but also will not take up too much area, thereby greatly saving drying space. If the requirements for layers of sheets are high, this layer rack mechanism can be pushed into a closed room. Since the high multi-layer space is utilized, the room does not need to be too large to accommodate a large number of sheets.

[0035] At the same time, the shelves are assisted by the tension springs 12 of corresponding heights, which facilitate lifting and flattening, and can conveniently load and unload materials and operate each shelf. The lifted shelf will not fall and scratch the lower shelf, and the gravity of the sheet combined with the spring can assist the shelf support and reduce the pressure of each shelf on the lower layer.
