Description

Technical Field

[0001] This utility model relates to the field of plywood processing technology, and in particular to a plywood pressing device. Background Technology

[0002] Plywood is a type of engineered wood product made by bonding multiple layers of veneers (usually wood veneers, but also including special materials such as bamboo veneers and fiberboard) together with adhesives (commonly urea-formaldehyde resin adhesives, phenolic resin adhesives, etc.) and pressing them together. As a basic category of engineered wood products, plywood is widely used in furniture, construction, packaging, and transportation (such as automotive interior panels) due to its advantages of high cost-effectiveness, convenient processing, and stable performance. It is one of the key products with the largest usage and widest application in the modern wood processing industry.

[0003] In related technologies, plywood pressing is mostly carried out using a stacked batch pressing method. Operators stack the glued and assembled plywood blanks one by one onto the lower platen of the pressing device. Once the number of stacked blanks reaches the upper limit of the equipment's single pressing, the pressing device is started, allowing the adhesive to cure under pressure, thus completing the bonding and shaping of the plywood. However, during the pressing process of multiple glued plywoods stacked together, the plywoods are prone to shifting and tilting, affecting the pressing quality. Furthermore, the glue that overflows during the pressing process can remain on the surface of the pressed plywood, easily causing contamination for subsequent pressing operations, thereby affecting the quality of the new batch of plywood. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a plywood pressing device that can stack plywood in layers to avoid shifting or tilting when pressing and shaping a larger number of plywood, thus affecting the pressing quality. After pressing, the contact plate can scrape off the overflowing glue while assisting manual feeding, preventing residual contamination of subsequent pressing operations.

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The plywood pressing device of this utility model is described below with reference to the accompanying drawings.

[0017] like Figures 1-4 As shown, the plywood pressing device of this utility model embodiment may include: a pressing equipment body 1, a hydraulic cylinder 2, a pressing plate assembly 3, a connecting mechanism 4, and an auxiliary mechanism 5, wherein the hydraulic cylinder 2 is disposed on the pressing equipment body 1; the pressing plate assembly 3 is movably disposed on the pressing equipment body 1 through the hydraulic cylinder 2.

[0018] It should be noted that the pressing equipment body 1 described in this embodiment is composed of a base plate, a column and an upper plate. The column is vertically fixed on the upper surface of the base plate, and the upper plate is horizontally set on the top of the column, together forming a stable frame structure.

[0019] In addition, it should be noted that the hydraulic cylinder 2 described in this embodiment is detachably mounted on the upper plate by bolts. The output end of the hydraulic cylinder 2 extends downward and connects to the top of the pressing plate assembly 3. At the same time, the edge of the pressing plate assembly 3 is provided with a sliding hole adapted to the column. The column passes through the sliding hole so that the pressing plate assembly can slide along the column and avoid the pressing plate assembly from shifting or tilting during the operation.

[0020] The connecting mechanism 4 is connected between each pressing plate of the pressing plate group 3; the auxiliary mechanism 5 includes a driving component 51 and a cleaning component 52, wherein the driving component 51 is disposed on the pressing equipment body 1; and the cleaning component 52 is disposed on the pressing plate group 3.

[0021] It should be noted that the connecting mechanism 4 described in this embodiment is symmetrically arranged in two places about the center point of the pressing plate group 3, so as to avoid the problem of each pressing plate shifting or tilting due to unilateral force during the up and down movement of the pressing plate group 3.

[0022] Specifically, before the pressing operation begins, the operator can place the plywood to be pressed into the gap between each pressing plate. After starting the hydraulic cylinder 2, the hydraulic cylinder 2 will drive the pressing plate group 3 to move downward along the column of the pressing equipment body 1. During this process, the pressing plate group 3 will apply pressure synchronously, so that all plywood are evenly stressed. When the pressing force reaches the preset value, the hydraulic cylinder 2 will maintain the pressure for a period of time to complete the pressing and shaping of the plywood.

[0023] After pressing is completed, hydraulic cylinder 2 drives pressing plate group 3 to rise. At this time, connecting mechanism 4 will pull each pressing plate upward synchronously to separate them, so that a uniform gap is formed between each pressing plate. Further, auxiliary mechanism 5 is activated, so that auxiliary mechanism 5 drives the contact plate 7 to move through belt 6, thereby pushing the plywood during the movement.

[0024] In one embodiment of this utility model, such as Figure 3 As shown, the connecting mechanism 4 includes a fixing post 41 and a limiting plate 42. The fixing post 41 is disposed on the side wall of the pressing plate assembly 3; the limiting plate 42 is movably disposed on the pressing plate assembly 3 through the fixing post 41.

[0025] It is understood that the limiting plate 42 described in this embodiment is provided with a guide groove that is compatible with the fixing post 41. The fixing post 41 passes through the guide groove, so that the limiting plate 42 can slide along the fixing post 41. The guide groove can effectively limit the movement trajectory of the limiting plate 42 and prevent it from tilting or falling off during the pressing process of the pressing plate assembly 3, thereby ensuring that the pressing plate assembly 3 can operate stably during the pressing and separation process.

[0026] Specifically, when the pressing is completed and the hydraulic cylinder 2 drives the pressing plate group 3 to rise, the limiting plate 42 will slide upward along the fixed column 41, so that the two ends of the limiting plate 42 abut against the fixed column 41 on the adjacent pressing plate, thereby causing the adjacent pressing plates to separate. Since the length of the limiting plate 42 is fixed, it ensures that a uniform gap is formed after all the pressing plates are separated.

[0027] In one embodiment of this utility model, such as Figure 2 As shown, the drive assembly 51 includes a mounting base 511, a drive motor 512, and a drive shaft 513. The mounting base 511 is disposed on the pressing device body 1; the drive motor 512 is disposed on the mounting base 511; and the drive shaft 513 is disposed on the mounting base 511 via the drive motor 512.

[0028] It should be noted that the mounting base 511 described in this embodiment is fixed to the top of the pressing equipment body 1 by means of bolt connection.

[0029] Additionally, it should be noted that the drive shaft 513 described in this embodiment is rotatably mounted on the mounting base 511 via bearings.

[0030] Specifically, when the drive motor 512 starts, the drive motor 512 will drive the drive shaft 513 to rotate synchronously, and then drive the cleaning component 52 to move through the drive shaft 513.

[0031] In one embodiment of this utility model, such as Figure 4 As shown, the cleaning assembly 52 includes a first base 521, a bushing 522, a first pulley 523, two second bases 524, and a second pulley 525. The first base 521 is disposed on the side wall of the pressing plate assembly 3, and the bushing 522 is disposed on the first base 521 through the first base 521. The first pulley 523 is disposed on the bushing 522. The two second bases 524 are symmetrically disposed on the pressing plate assembly 3, and each of the two second bases 524 is connected to a second pulley 525.

[0032] It should be noted that the bushing 522 described in this embodiment has a through groove in the middle that matches the drive shaft 513. The drive shaft 513 passes through the through groove, thereby driving the bushing 522 to rotate. The drive shaft 513 and the bushing 522 are slidably connected.

[0033] Specifically, when the drive shaft 513 rotates, it will drive the first pulley 523 to rotate through the bushing 522. Since the first pulley 523 is connected to the second pulleys 525 on the two second bases 524 through the transmission belt 6, the first pulley 523 drives the second pulleys 525 to rotate synchronously through the belt 6.

[0034] In one embodiment of this utility model, such as Figure 2 As shown, the outer sides of the first pulley 523 and the second pulley 525 are attached to the belt 6, and the belt 6 is provided with an abutment plate 7.

[0035] It should be noted that the bottom end of the contact plate 7 described in this embodiment is attached to the surface of the pressing plate assembly 3.

[0036] In addition, it should be noted that a collection box for collecting residual adhesive is provided at one end of the pressing plate assembly 3.

[0037] Specifically, when the belt 6 moves, it will drive the contact plate 7 to move synchronously, so that the contact plate 7 moves to the surface of the pressing plate assembly 3. Before pressing, the belt 6 drives the contact plate 7 to move to one end of the pressing plate assembly 3, so as to avoid the contact plate 7 affecting the pressing operation of the pressing plate assembly 3. After pressing, the belt 6 will drive the contact plate 7 to scrape off the residual adhesive on the pressing plate assembly 3. The scraped adhesive will slide along the surface of the pressing plate assembly 3 into the preset collection box under the push of the contact plate 7, so as to avoid the adhesive dripping onto other parts of the equipment or the ground and causing pollution.

[0038] During this process, the contact plate 7 will simultaneously push the pressed plywood to the same side while scraping off the adhesive, until the plywood is pushed to the edge of the pressing plate group 3, making it convenient for operators to pick up the material directly and reducing the amount of manual handling work.

[0039] In summary, the plywood pressing device of this utility model, through the cooperation of hydraulic cylinder 2 and connecting mechanism 4, drives the pressing plate group 3 to rise and form a layered spacing, so as to realize the stacking of more plywood in three layers, while effectively avoiding the offset and tilting problem caused by the large number of boards, thus improving the quality of the pressed and shaped product. After pressing, the auxiliary mechanism 5 drives the contact plate 7 to slide along the surface of the pressing plate group through belt 6. While assisting manual unloading, the contact plate 7 scrapes off the glue overflowing onto the pressing plate group, avoiding glue residue from causing pollution to subsequent pressing operations.
