Description

Technical Field

[0001] This utility model relates to the field of laminating press technology, and in particular to a single-sided laminating press for decorative panels. Background Technology

[0002] The single-sided veneer press is mainly used to bond various decorative materials to the surface of artificial boards (such as plywood, blockboard, MDF, particleboard, etc.) or other solid wood boards to form boards with decorative effects.

[0003] Chinese Patent CN212949626U discloses a veneer device for wood veneer panels. This device adjusts the height of the pressure roller and the pulley on the guide roller according to the thickness of the plywood by activating a guide roller and a micro-fan. It then activates a push rod motor, whose output pushes a connecting plate downwards. The connecting plate moves two first hinge rods, which in turn move two sliders closer together. The sliders then move the tops of two second hinge rods away from each other. The bottoms of the two second hinge rods then push a pressure plate downwards. The pressure plate then moves a pressure roller, which places the plywood on top of the panel and positions it on two... Between the alignment plates, the threaded rod is rotated to adjust the two alignment plates according to their size until the panel and plywood are completely aligned. Then, the material is put in through the feed port, sent to the guide roller through the guide plate, squeezed by the pressure roller, and finally discharged from the discharge port. This structure is simple and easy to use, and realizes the adjustment of the distance between the pressing mechanism and the conveying mechanism, improving the quality of finished products and reducing economic losses. However, in the process of veneer panel lamination, uneven pressing and easy falling off or damage of the veneer material can lead to problems such as low veneer quality and low efficiency. In view of this, a single veneer panel lamination press is provided. Utility Model Content

[0004] The main purpose of this utility model is to provide a single-sided laminate press for decorative panels, so as to solve the problems of uneven pressing and easy detachment or damage of the laminate material during the laminate process, which result in poor laminate quality and low efficiency.

[0005] To achieve the above objectives, according to one aspect of this utility model, a single-sided veneer press for decorative panels is provided, comprising a worktable and a support frame fixedly mounted thereon. A fixed rod is fixedly connected to the support frame, and two sliders are symmetrically slidably mounted on the fixed rod. Each slider has a connecting rod hinged to its bottom. A common fixed plate is hinged between the two connecting rods. A pressure plate for adsorbing veneer material is fixedly connected to the bottom of the fixed plate. Adjusting rods are symmetrically hinged to both sides of the bottom of the fixed plate. Limiting plates are fixedly connected to the side walls of the adjusting rods. The limiting plates are used to fix the veneer material at the bottom of the pressure plate. An mounting plate for fixing the decorative panel is also fixedly mounted on the worktable, and support plates are provided on both sides of the mounting plate.

[0006] Furthermore, a push rod motor is fixedly installed at the center of the bottom of the connecting rod, and the output shaft of the push rod motor is fixedly connected to the center of the fixed plate, and the output shaft of the push rod motor is a telescopic rod.

[0007] Furthermore, each of the sliders is fixedly connected to a first mounting base at its bottom, and each of the two sides of the fixing plate is fixedly connected to a second mounting base. Each of the two ends of the connecting rod is connected to a connecting shaft, with the connecting shaft at one end of the connecting rod rotatably mounted on the first mounting base and the connecting shaft at the other end of the connecting rod rotatably mounted on the second mounting base.

[0008] Furthermore, the pressure plate has a heating cavity and a heat conduction cavity, the heating cavity is located above the heat conduction cavity, and the bottom of the pressure plate has a number of vent holes in a rectangular array, the vent holes are connected to the heat conduction cavity, and the bottom of the pressure plate has a cutting groove.

[0009] Furthermore, a third mounting base is fixedly connected to both sides of the bottom of the fixed plate, and a limit shaft is connected to one end of the adjusting rod. The limit shaft on the adjusting rod is rotatably mounted on the third mounting base.

[0010] Furthermore, the adjusting rod is arc-shaped, and a number of ball bearings are rotatably embedded in the lower end of the adjusting rod. The limiting plate is inverted L-shaped, and one side wall of the limiting plate is in contact with the edge of the lower surface of the pressure plate.

[0011] Furthermore, the mounting plate has a mounting groove for fixing the decorative panel, a sliding plate is slidably installed in the mounting groove, a number of springs are fixedly connected to the side wall of the sliding plate, the other end of the springs is fixedly connected to the side wall of the mounting groove, and a cutting tool is provided on the upper surface of the mounting groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this single-sided veneer press, the adjusting rod is fixedly connected to the limiting plate on its side wall. Its side wall contacts the edge of the lower surface of the pressing plate, which effectively prevents the veneer material at the bottom of the pressing plate from falling off accidentally before pressing, thus improving the stability and safety of operation. As the pressure of the pressing plate gradually increases, the adjusting rod can rotate around its pivot point, thereby causing the limiting plate to separate from the pressing plate. This ensures the stability of the veneer material before pressing and avoids interference of the limiting plate with the pressing plate during the pressing process.

[0015] 2. In this single-sided veneer press, a support plate is provided. The upper end of the support plate is made of rigid material and the lower end is made of elastic material. This not only ensures the support force of the veneer material during the pressing process, but also avoids damage to the support plate due to excessive pressure, thus playing a dual role of guiding and supporting.

[0033] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0034] Please see Figures 1-11 As shown, the purpose of this embodiment is to provide a single-sided veneer press for decorative panels, including a workbench 1 and a support frame 11 fixedly installed on it. A fixed rod 12 is fixedly connected to the support frame 11. Two sliders 13 are symmetrically slidably installed on the fixed rod 12. The bottom of each slider 13 is hinged to a connecting rod 2. The two connecting rods 2 are hinged to the same fixed plate 3. A pressure plate 4 for adsorbing the veneer material is fixedly connected to the bottom of the fixed plate 3. Adjusting rods 5 are symmetrically hinged to the bottom sides of the fixed plate 3. A limiting plate 51 is fixedly connected to the side wall of the adjusting rod 5. The limiting plate 51 is used to fix the veneer material at the bottom of the pressure plate 4. An installation plate 6 for fixing the decorative panel is also fixedly installed on the workbench 1. Support plates 65 are provided on both sides of the installation plate 6.

[0035] A push rod motor 14 is fixedly installed at the bottom center of the connecting rod 2. The output shaft of the push rod motor 14 is fixedly connected to the center of the fixed plate 3. The output shaft of the push rod motor 14 is a telescopic rod to ensure that the extension or retraction of its output shaft can meet the specific requirements of the bonding operation of the bonding material.

[0036] The bottom of each slider 13 is fixedly connected to a first mounting base 131, and both sides of the fixed plate 3 are fixedly connected to second mounting bases 31. Both ends of the connecting rod 2 are connected to connecting shafts. The connecting shaft at one end of the connecting rod 2 is rotatably mounted on the first mounting base 131, and the connecting shaft at the other end of the connecting rod 2 is rotatably mounted on the second mounting base 31, allowing the connecting rod 2 to rotate around its hinge point when subjected to external force. When the push rod motor 14 is started, its output shaft begins to extend and directly pushes the fixed plate 3 downward. Since both ends of the connecting rod 2 are hinged to the first mounting base 131 and the second mounting base 31 respectively, when the fixed plate 3 moves, the connecting rod 2 will rotate around its hinge point. The rotating connecting rod 2 will drive the slider 13 to slide along the fixed rod 12, and the two sliders 13 will approach each other. At the same time, the upper ends of the connecting rod 2 will also approach each other due to the downward movement of the fixed plate 3, until the pressure plate 4 and the decorative panel are in close contact, realizing the bonding of the veneer material.

[0037] The bottom of the pressure plate 4 absorbs the facing material. During the facing process, appropriate heating of the facing material can promote its softening, making it adhere better. Therefore, the pressure plate 4 has a heating cavity 41 and a heat-conducting cavity 42. The heating cavity 41 is equipped with a heating wire, and the heat-conducting cavity 42 is equipped with an aluminum alloy plate. The heating cavity 41 is located above the heat-conducting cavity 42. Therefore, the heat from the heating cavity 41 is first transferred to the heat-conducting cavity 42, and then the heat-conducting cavity 42 transfers the heat to the facing material. The heat-conducting cavity 42... It can effectively receive the heat transferred from the heating chamber 41, and avoid the heat being transferred to the surface material too quickly and too high, which would cause the surface material to soften, fall off or break quickly. The bottom of the pressure plate 4 has a number of ventilation holes 43 in a rectangular array. The ventilation holes 43 are connected to the heat conduction chamber 42. Heat will penetrate to the surface of the surface material through the ventilation holes 43, which can promote the heat in the heat conduction chamber 42 to be transferred to the surface material more evenly, thereby softening it evenly. The bottom of the pressure plate 4 has a cutting groove 44.

[0038] Both sides of the bottom of the fixed plate 3 are fixedly connected to the third mounting base 32. One end of the adjusting rod 5 is connected to the limiting shaft. The limiting shaft on the adjusting rod 5 is rotatably mounted on the third mounting base 32, so that the adjusting rod 5 can rotate around its rotation fulcrum when subjected to external force.

[0039] The adjusting rod 5 is arc-shaped, and a number of ball bearings 52 are embedded in the lower end of the adjusting rod 5 for rotation. The limiting plate 51 is inverted L-shaped, and one side wall of the limiting plate 51 contacts the edge of the lower surface of the pressure plate 4 to prevent the bonding material at the bottom of the pressure plate 4 from accidentally falling off before pressing.

[0040] Therefore, when the output shaft of the push rod motor 14 pushes the fixed plate 3 downward, and the adjusting rod 5 gradually contacts the upper surface of the worktable 1, as the downward pressure gradually increases, the limiting shaft at one end of the adjusting rod 5 rotates within the third mounting base 32. This rotation drives the other end of the adjusting rod 5 to move away from the mounting plate 6. As the adjusting rod 5 moves, the ball bearing 52 at its bottom rolls smoothly on the upper surface of the worktable 1. The ball bearing 52 greatly reduces the friction when the adjusting rod 5 moves on the upper surface of the worktable 1, ensuring the smoothness and continuity of the pressing process. As the adjusting rod 5 rotates hingedly, the limiting plate 51 gradually separates from the pressure plate 4, losing its supporting and fixing function for the facing material. At this time, the support plate 65 set on the mounting plate 6 can respond quickly, providing necessary support force to the edge of the facing material, preventing the facing material from falling off in a softened state.

[0041] The mounting plate 6 has a mounting groove 61 for fixing the decorative panel. A sliding plate 62 is slidably installed in the mounting groove 61. Several springs 63 are fixedly connected to the side wall of the sliding plate 62. The mounting groove 61 on the other side of the sliding plate 62 is used to place the decorative panel. The other end of the spring 63 is fixedly connected to the side wall of the mounting groove 61. The elastic force of the spring 63 allows the sliding plate 62 to tightly press against the decorative panel, thereby achieving a stable fixation of the decorative panel. Moreover, the thickness of the mounting plate 6 is less than the thickness of the decorative panel, so the upper end of the decorative panel can be exposed, which is convenient for subsequent surface finishing and observation.

[0042] Because the area of ​​the veneer material is larger than that of the decorative panel, the edges of the veneer material often stick together when the veneer is pressed down, affecting the aesthetics and quality of the veneer. Therefore, a cutter 64 is provided on the upper surface of the mounting groove 61. The cutter 64 is tightly fitted to the side wall of the decorative panel, and the tip of the cutter 64 is higher than the upper surface of the decorative panel. When the pressure plate 4 is pressed down, the tip of the cutter 64 will be inserted into the cutting groove 44. As the pressure plate 4 continues to press down, the cutter 64 will cut off the excess part of the veneer material along the path of the cutting groove 44, thereby ensuring that the veneer material can be tightly and perfectly attached to the decorative panel.

[0043] The mounting plate 6 has slots 66 on both sides, and two limiting slots 15 are symmetrically provided on the worktable 1. The slots 66 and the limiting slots 15 are respectively connected. The support plate 65 is set in the slots 66 and the limiting slots 15. The upper end of the support plate 65 is made of rigid material, and the lower end of the support plate 65 is made of elastic material. Therefore, when the support plate 65 comes into contact with the facing material on the lower surface of the pressure plate 4 and is subjected to pressure, the elastic material at the lower end of the support plate 65 is compressed by the pressure as the pressure plate 4 is pressed down. Therefore, the rigid material at the upper end of the support plate 65 slides into the slots 66 and the limiting slots 15. The rigid material at the upper end of the support plate 65 also plays a guiding role to prevent the support plate 65 from shifting and being damaged.

[0044] In practical use, the decorative panel is placed in the mounting groove 61 of the mounting plate 6. The combination of the sliding plate 62 and the spring 63 secures the decorative panel. The veneer material is adsorbed onto the bottom of the pressure plate 4. The push rod motor 14 is started, and its output shaft extends to push the fixed plate 3 downward. The connecting rod 2 rotates around its hinge point, causing the slider 13 to slide along the fixed rod 12 until the pressure plate 4 is in close contact with the decorative panel. During the pressing process, the limiting shaft of the adjusting rod 5 rotates in the third mounting seat 32, causing the other end of the adjusting rod 5 to shift. The ball bearing 52 rolls smoothly on the upper surface of the worktable 1, and the limiting plate 51 gradually separates from the pressure plate 4. At this time, the support plate 65 set on the mounting plate 6 can quickly support the edge of the veneer material. When the pressure plate 4 is pressed down, the tip of the cutter 64 is inserted into the cutting groove 44 to cut off the excess part of the veneer material. During this process, the heating chamber 41 in the pressure plate 4 transfers heat to the veneer material through the heat conduction chamber 42 and the vent 43 to promote its softening.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
