Description

Technical Field

[0001] This utility model relates to the field of plywood pressing devices, and in particular to an anti-warping plywood pressing device. Background Technology

[0002] Plywood, as a type of engineered wood product widely used in construction, furniture manufacturing, packaging, and many other fields, directly affects the quality of related products. In the production process of plywood, pressing is a crucial step, and the pressing effect directly determines the quality of the plywood, especially the key indicator of warpage. Warped plywood not only affects its appearance but also reduces its stability and reliability in actual use. Therefore, inventing an anti-warping plywood pressing device is of great significance.

[0003] However, existing plywood pressing devices have many shortcomings.

[0004] In terms of positioning, although traditional pressing devices can block the plywood on the left and right sides to keep it aligned, the front and back sides lack such blocking devices because they need to be loaded and unloaded. This makes it difficult to ensure that the front and back sides of multi-layer plywood are aligned before pressing, which makes the force on each layer uneven during pressing, easily causing the plywood to warp and reducing the flatness and dimensional accuracy of the product.

[0005] Therefore, an anti-warping plywood pressing device is proposed to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an anti-warping plywood pressing device, which aims to improve the problem in the prior art that it is difficult to ensure the alignment of the front and back sides of multi-layer plywood before and after pressing, resulting in uneven stress on each layer and product warping during pressing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an anti-warping plywood pressing device, comprising a punching machine, a hydraulic cylinder provided on the inner wall of the top of the punching machine, a pressure plate fixedly connected to the bottom end of the output shaft of the hydraulic cylinder, and a positioning mechanism provided on the outer wall of the punching machine, the positioning mechanism comprising a clamping component and a drive guiding component;

[0008] The clamping assembly includes a support block, which is fixedly connected to the front surface of the press. A rotating shaft is rotatably connected to the inner surface of the support block. A guide plate is fixedly connected to the left end of the upper surface of the rotating shaft. A clamping plate is slidably connected to the upper surface of the guide plate. An adaptive component is provided on the rear surface of the guide plate.

[0009] As a further description of the above technical solution:

[0010] The drive guide assembly includes a support plate, which is fixedly connected to the right surface of the stamping machine. A motor is provided on the upper surface of the support plate. A screw is fixedly connected to the output shaft of the motor. A movable plate is threadedly connected to the outer wall of the screw. A slider is slidably connected to the upper surface of the movable plate. A connecting plate is hinged to the top of the inner surface of the slider.

[0011] As a further description of the above technical solution:

[0012] The adaptive component includes a slide bar that extends through and is slidably connected to the front surface of a guide plate, the rear surface of which is elastically connected to the front surface of a clamping plate via a compression spring.

[0013] As a further description of the above technical solution:

[0014] The pressure plate is slidably connected to the inner surface of the stamping machine.

[0015] As a further description of the above technical solution:

[0016] The screw passes through and is rotatably connected to the inner surface of the support plate, and the movable plate is slidably connected to the right surface of the press.

[0017] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the positioning mechanism is used to achieve the positioning of multi-layer plywood. The motor drives the screw to make the moving plate move and drive the clamping plate to open and close, which can quickly and accurately align the front and back sides of multiple stacked plywoods. This effectively avoids uneven force on each layer during pressing due to inaccurate positioning, and ensures the flatness of subsequent plywood pressing, thus improving the processing quality.

[0025] 2. In this utility model, the clamping of the plywood by the adaptive components is elastic. This clamping method ensures stable positioning and provides a reasonable deformation range for the plywood during pressing, avoiding obstruction.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 2This utility model provides an embodiment of an anti-warping plywood pressing device, including a punch press 1. A hydraulic cylinder 2 is provided on the inner wall of the top of the punch press 1. Both the punch press 1 and the hydraulic cylinder 2 are existing technologies and can be implemented by those skilled in the art. Since they are existing technologies, they will not be described in detail in this case. A pressure plate 3 is fixedly connected to the bottom end of the output shaft of the hydraulic cylinder 2. After the hydraulic cylinder 2 is started, it can drive the pressure plate 3 to move longitudinally. A positioning mechanism is provided on the outer wall of the punch press 1. The positioning mechanism can clamp and position the plywood to be pressed, ensuring that multiple sets of plywood are aligned before pressing and preventing the edges of the plywood from warping during pressing. The positioning mechanism includes a clamping component and a drive guide component.

[0034] Reference Figure 1 - Figure 3 The clamping assembly includes a support block 51, which is fixedly connected to the front surface of the press 1. A rotating shaft 52 is rotatably connected to the inner surface of the support block 51, and the support block 51 provides support for the rotating shaft 52. A guide plate 53 is fixedly connected to the left end of the upper surface of the rotating shaft 52. When the rotating shaft 52 rotates, it will drive the guide plate 53 to swing. A clamping plate 54 for clamping the plywood is slidably connected to the upper surface of the guide plate 53. An adaptive component is provided on the rear surface of the guide plate 53. The adaptive component can make the clamping of the plywood by the clamping plate 54 not a rigid clamping, so that there is a deformation range when the plywood is pressed.

[0035] Reference Figure 1 - Figure 3 The drive guide assembly includes a support plate 42, which is fixedly connected to the right surface of the press 1. A motor 41 is provided on the upper surface of the support plate 42. The motor 41 is a servo motor, which is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. A screw 43 is fixedly connected to the output shaft of the motor 41. After the motor 41 is started, it can drive the screw 43 to rotate. A movable plate 44 is threadedly connected to the outer wall of the screw 43. When the screw 43 rotates, it will drive the movable plate 44 to move longitudinally. When the movable plate 44 moves upward, the clamping plate 54 will unfold to facilitate the placement of the plywood. When the movable plate 44 moves downward, the clamping plate 54 will close together to clamp and position the plywood. A slider 45 is slidably connected to the upper surface of the movable plate 44. The slider 45 moves in the back-and-forth direction. A connecting plate 46 is hinged to the top of the inner surface of the slider 45.

[0036] Reference Figure 1 - Figure 3The pressure plate 3 is slidably connected to the inner surface of the press 1 and moves longitudinally to maintain stability during movement. The screw 43 passes through and is rotatably connected to the inner surface of the support plate 42. The moving plate 44 is slidably connected to the right surface of the press 1. The front end of the connecting plate 46 is fixedly connected to the right end of the rear surface of the rotating shaft 52. When the slider 45 moves longitudinally with the moving plate 44, it will squeeze the connecting plate 46 to make it swing, which will drive the rotating shaft 52 to rotate.

[0037] Reference Figure 1 , Figure 3 , Figure 4 The adaptive component includes a slide rod 61, which is slidably connected to the front surface of the guide plate 53. The slide rod 61 moves in the back-and-forth direction. The rear surface of the guide plate 53 is elastically connected to the front surface of the clamping plate 54 through a compression spring 62. The elasticity is strong, and the relative position of the clamping plate 54 and the guide plate 53 can remain stable under no large pressure. The adaptive component, clamping component, slider 45 and connecting plate 46 are all provided in two sets, which are symmetrically distributed in the back-and-forth direction with the center line of the moving plate 44. The rear surface of the slide rod 61 is fixedly connected to the front surface of the clamping plate 54. The clamping plate 54 and the slide rod 61 will move synchronously. The compression spring 62 is sleeved on the outer wall of the slide rod 61.

[0038] Working principle: Start motor 41, which drives screw 43 to rotate. The rotation of screw 43 causes moving plate 44 to move upward. Slider 45 on the upper surface of moving plate 44 moves upward accordingly. Slider 45 presses connecting plate 46 to make it swing. Connecting plate 46 drives rotating shaft 52 to rotate, which in turn causes guide plate 53 to swing. Clamping plate 54 unfolds, making it convenient to place plywood on press 1. Then start motor 41 to drive screw 43 to reverse, moving plate 44 downward. Slider 45 also moves downward synchronously. Slider 45 drives connecting plate 46 to swing. Connecting plate 46 pushes rotating shaft 52 to rotate in the opposite direction. Guide plate 53 swings in the opposite direction. Clamping plate 54 moves towards the middle to clamp plywood, aligning the front and back sides of multiple stacked plywood.

[0039] Due to the adaptive component, the clamping plate 54 does not rigidly clamp the plywood. The slide bar 61 passes through the guide plate 53 and the clamping plate 54 is elastically connected to the guide plate 53 through the compression spring 62. When there is no large pressure, the relative position of the clamping plate 54 and the guide plate 53 is stable, which can stably clamp and position the plywood, ensure that multiple sets of plywood are aligned before pressing, and at the same time avoid the edge of the plywood from warping during pressing.

[0040] Then, start the hydraulic cylinder 2, which drives the pressure plate 3 to slide longitudinally downward on the inner surface of the press 1, pressing the plywood placed on the guide plate 53. The pressure plate 3 remains stable during the movement and can apply pressure evenly to the plywood to complete the pressing work. After the pressing is completed, start the motor 41 to drive the clamping plates 54 on both sides to unfold, and then remove the plywood.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
