Description

Technical Field

[0001] The utility model relates to the technical field of composite bamboo board processing, in particular to a hot pressing and feeding device for preparing composite bamboo boards. Background Technique

[0002] Bamboo is longitudinally split into strips and processed into bamboo strip curtains; the residues from sawing and veneer cutting (such as board skins, wood cores, etc. waste materials) or small-diameter wood are rolled into a net-shaped wood bundle and sewn into a wood bundle curtain; using veneer cut from rotary cutting as the constituent unit, after drying and sizing respectively, then using the wood bundle curtain as the core layer, the bamboo strip curtain as the inner layer, the veneer as the surface layer, and if necessary, there can also be a layer of impregnated paper on the surface layer, and combined into a billet with a symmetrical layered structure, and hot pressed and glued into a bamboo-wood composite board.

[0003] Most of the existing hot presses for hot pressing composite bamboo boards press multiple layers of bamboo board materials together after gluing. During the pressing process, the composite bamboo boards need to be manually fed onto the working surface of the hot press for hot pressing. However, manual feeding may cause the composite bamboo boards to collide with the hot press, resulting in damage to the bamboo boards or injury to the staff, and the work efficiency is low.

[0004] In the patent document with the publication number of CN111823690A, it discloses a hot pressing device and hot pressing process for multi-layer composite bamboo board materials. Before pressing, part of the air inside is pumped out through a vacuum pumping mechanism to form a negative pressure between the pressing upper cover plate and the pressing bottom plate; the four-sided outer wrappers of the facing material, bottom material and middle material are respectively pressed by a veneer press.

[0005] However, this hot pressing device and hot pressing process for multi-layer composite bamboo board materials do not have a suitable feeding device. During use, manual feeding operation is required, which may reduce the work efficiency. In the case of too heavy boards, it may cause injury to the staff. Therefore, a hot pressing and feeding device for preparing composite bamboo boards needs to be proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 - 4 , the present invention provides a technical solution:

[0025] Embodiment 1:

[0026] A hot pressing and feeding device for preparing a composite bamboo board, including a support plate 1 and a top plate 2 arranged on the top of the support plate 1. A pushing mechanism is arranged on one side of the support plate 1, and a limiting mechanism is arranged on one side of the top plate 2;

[0027] The limiting mechanism includes side plates 201, guide rods 202, first springs 203, mounting parts 204, limiting rods 205, clamping plates 206, mounting blocks 207 and second springs 208. The side plates 201 are fixedly connected to one side of the top plate 2. The guide rods 202 are fixedly connected to one side of the side plates 201. The first springs 203 are movably connected to one side of the side plates 201. The mounting parts 204 are fixedly connected to the top of the top plate 2. The limiting rods 205 are fixedly connected to one side of the mounting parts 204. A rotating shaft is provided inside the mounting parts 204. The clamping plates 206 are rotatably connected to the rotating shaft. One side of the clamping plates 206 is set as an inclined surface. The clamping plates 206 rotate around the mounting parts 204. The clamping plates 206 are rotatably connected to one side of the mounting parts 204. The mounting blocks 207 are fixedly connected to the top of the top plate 2. The second springs 208 are movably connected to one side of the mounting blocks 207. Spring pads are provided at both ends of the first springs 203 and the second springs 208 to prevent loosening and protect the supporting surface during operation. After one feeding is completed, the clamping plate 206 is pushed inward so that the clamping plate 206 no longer limits the limiting plate 105. At this time, under the action of its restoring force, the first spring 203 generates a restoring force, causing the limiting plate 105 to rebound and no longer be limited by the clamping plate 206. Finally, the limiting plate 105 is restored to its initial position for the next feeding.

[0028] Embodiment 2:

[0029] On the basis of Embodiment 1, the pushing mechanism includes telescopic rods 101, upward pushing cylinders 102, pushing cylinders 103, support plates 104, limiting plates 105 and rollers 106. The telescopic rods 101 are fixedly connected to the top of the support plate 1. The upward pushing cylinders 102 are arranged on the top of the support plate 1. The pushing cylinders 103 are fixedly connected to the top of the top plate 2. The support plates 104 are arranged on one side of the pushing cylinders 103. The limiting plates 105 are arranged on one side of the support plates 104. The rollers 106 are arranged at the bottom of the support plates 104. A through hole for cooperating with the guide rod 202 is provided on one side of the limiting plate 105. The guide rod 202 can guide the limiting plate 105. Six rollers 106 are evenly distributed at the bottom of the support plate 104, which can reduce the friction generated at the bottom when pushing the support plate 104. When the limiting plate 105 is restricted by the clamping plate 206, most of the area of the composite bamboo board on the top of the support plate 104 has been on the top of the hot pressing workbench surface. At this time, the pushing cylinder 103 drives the support plate 104 to return. However, the limiting plate 105 has been restricted. When the support plate 104 returns, the limiting plate 105 will not return accordingly. The limiting plate 105 can limit the composite bamboo board pushed into the hot press, so that when the support plate 104 returns, the composite bamboo board will not return accordingly, achieving the purpose of unloading.

[0030] A support frame 3 is fixedly connected to the bottom of the support plate 1. A universal wheel 4 is provided at the bottom of the support frame 3. The universal wheel 4 is a self-locking universal wheel 4, which can be freely moved when moving the equipment, reducing the inconvenience caused by movement.

[0031] Working principle:

[0032] First of all, through the set pushing mechanism, after placing the composite bamboo board on the top of the pallet 104, the top plate 2 of the feeding device can be pushed out to the working surface of the hot press by the top cylinder 102. It is necessary to make the top of the top plate 2 and the top of the working surface of the hot press as flush as possible. It should be noted that before placing the composite bamboo board, the limit plate 105 needs to be reset to the left side of the pallet 104. Subsequently, starting the push cylinder 103 can slowly push the pallet 104 out to the working surface of the hot press. Since rollers 106 are provided at the bottom of the pallet 104, the friction generated during pushing can be reduced.

[0033] Furthermore, through the set limiting mechanism, when the push cylinder 103 pushes the pallet 104 out to the working surface of the hot press, one side of the limit plate 105 will contact one side of the clamping plate 206. Continuing to push will squeeze the clamping plate 206, causing the clamping plate 206 to rotate around the mounting member 204 and squeeze the second spring 208. At the same time, one side of the limit plate 105 will squeeze the first spring 203. When the limit plate 105 completely passes one side of the clamping plate 206, the mounting block 207 will generate a resilience under the action of its restoring force, causing the clamping plate 206 to return to its initial position.

[0034] Furthermore, when the limit plate 105 is restricted by the clamping plate 206, most of the area of the composite bamboo board on the top of the pallet 104 is already on the top of the working surface of the hot press. At this time, the push cylinder 103 drives the pallet 104 to return. However, the limit plate 105 has been restricted. When the pallet 104 returns, the limit plate 105 will not return with it. The limit plate 105 can limit the composite bamboo board pushed into the hot press, so that when the pallet 104 returns, the composite bamboo board will not return with it, achieving the purpose of unloading.

[0035] Even further, after one feeding is completed, push the clamping plate 206 inward so that the clamping plate 206 no longer restricts the limit plate 105. At this time, the first spring 203 generates a resilience under the action of its restoring force, causing the limit plate 105 to bounce back and no longer be restricted by the clamping plate 206. Finally, restore the limit plate 105 to its initial position for the next feeding.

[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.
