Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard processing, in particular to a static pressure device for wine box cardboard. Background Technique

[0002] The wine box cardboard is a multi-layer structure, which includes a core board, an inner paper and a face paper. After the wine box cardboard is prepared, it is necessary to perform static pressure and flattening on the cardboard structure so that the layer structures of the cardboard can be tightly pressed and bonded. The conventional static pressure device uses a hydraulic cylinder to drive a pressing plate to press down on the stacked cardboard. This kind of static pressure device will cause a pressure difference between the upper cardboard and the lower cardboard, and it is also easy to cause overpressure deformation of the cardboard after pressurization, affecting the quality of the cardboard. Patent application number CN202322557409.0 discloses a corrugated cardboard flattening device for corrugated paper processing, which includes a carrier vehicle and a flattening member. The carrier vehicle includes a flatbed truck, and sliding rods are fixed at the four corners of the top surface of the flatbed truck. The flattening member includes a bearing plate and a pressure member; the bearing plate includes a bottom plate, a top plate and a limiting cylinder. A plurality of support nails are fixed on the top surface of the bottom plate, and screw holes are opened at the four corners of the bottom plate; the bottom surface of the top plate is fixed to the support nails, and through holes are opened on the top plate opposite to the screw holes; the limiting cylinder passes through the through hole and is screwed with the screw hole; the limiting cylinder movably passes through the sliding rod; the pressure member is arranged on the top surface of the top bearing plate. Two bearing plates are used to clamp the corrugated cardboard, and the gap between the two bearing plates is adjusted through the limiting cylinder, which can not only ensure the flattening of the corrugated cardboard, but also avoid overpressure causing deformation in the thickness direction of the corrugated cardboard. Although this kind of flattening device can avoid the deformation of the corrugated cardboard, the loading and unloading are inconvenient and the flattening efficiency is low, affecting the production efficiency. Therefore, this application proposes a static pressure device for wine box cardboard. Summary of the Utility Model

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0018] Combined Figures 1 to 3 To illustrate this embodiment, this embodiment provides a hydrostatic pressure device for wine box cardboard, which includes a bottom plate 1. Four groups of optical rods 2 distributed in a matrix are fixedly connected to the bottom plate 1. Each group of optical rods 2 has four. A plurality of pressing plates 3 are slidably connected to each group of optical rods 2. The four optical rods 2 are distributed at the four corners of the pressing plate 3. Springs 4 are connected between adjacent pressing plates 3 and between the lowermost pressing plate 3 and the bottom plate 1. Four springs 4 are provided. The springs 4 are sleeved outside the optical rods 2. A top frame 5 is provided at the top of the optical rods 2. A hydraulic rod 6 is installed on the top frame 5. The hydraulic rod 6 is connected to the uppermost pressing plate 3. When the hydraulic rod 6 contracts, it drives the pressing plate 3 to move upward, thereby increasing the distance between adjacent pressing plates 3 and facilitating the placement of wine box cardboard.

[0019] A limiting strip groove 7 matching the pressing plate 3 is provided on the optical rod 2. The limiting strip groove 7 is arranged along the axial direction of the optical rod 2. A first pin member 8 penetrating the limiting strip groove 7 is provided on the side of the pressing plate 3. By sliding the first pin member 8 in the limiting strip groove 7, it is used to limit the distance of the upward or downward movement of the pressing plate 3, avoiding excessive downward pressure when the hydraulic rod 6 presses the pressing plate 3 and causing damage or deformation to the wine box cardboard.

[0020] The top frame 5 is a two-layer structure, including a plurality of cross beams and a plurality of longitudinal beams. A connecting rod 9 is fixedly connected to the top frame 5. The connecting rod 9 is fixedly connected to the roof of the factory building.

[0021] A connecting rod 10 is movably connected to the symmetric side of the pressing plate 3. The other end of the connecting rod 10 is detachably inserted into the side of the lower pressing plate 3 through a second pin member 11. When the hydraulic rod 6 pulls the pressing plate 3 upward, the upper pressing plate 3 whose distance needs to be enlarged is directly or indirectly connected to the uppermost pressing plate 3 through the connecting rod 10, thereby increasing the distance between the two pressing plates 3 and facilitating the placement of wine box cardboard. During hydrostatic pressure, the connecting rod 10 is not connected to the adjacent lower pressing plate 3.

[0022] When hydrostatic pressure needs to be applied to the wine box cardboard, the existence of the spring 4 can adopt two hydrostatic pressure methods.

[0023] The first hydrostatic pressure method is: during hydrostatic pressure, the spring 4 is in a stretched state, and the hydraulic rod 6 is separated from the uppermost pressing plate 3. At this time, the spring 4 contracts, causing adjacent two pressing plates 3 to approach each other and applying hydrostatic pressure to the wine box cardboard. This hydrostatic pressure method is suitable for low-pressure hydrostatic pressure, facilitating the tight adhesion of the glue between the layers of the wine box cardboard and ensuring uniform force on each layer of the wine box cardboard.

[0024] The first static pressure method is as follows: during static pressure, the spring 4 is in a contracted state, and the hydraulic rod 6 applies pressure to the uppermost pressing plate 3, and the spring 4 is used to sequentially transmit the force to the lower pressing plates 3 to improve the evenness of the force received by the wine box cardboard between layers, which is applicable to the static pressure of cardboard that requires strong pressure.

[0025] The working principle of the present utility model is: by arranging multiple pressing plates 3 at intervals, placing wine box cardboard between the pressing plates 3 and between the pressing plates 3 and the bottom plate 1 to achieve the purpose of statically pressing the wine box cardboard layer by layer. The hydraulic rod 6 cooperates with the spring 4 to apply pressure to the lower multiple pressing plates 3, improving the evenness of the force received by each layer of wine box cardboard, being able to flatten the wine box cardboard in batches, improving the processing efficiency, and facilitating loading and unloading.

[0026] It should be noted that in this text, 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 such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is 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 further includes elements inherent to such process, method, article or device.

[0027] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
