Abstract
Description
Technical Field
[0001] This utility model relates to the field of plywood production technology, specifically a plywood adding device. Background Technology
[0002] Plywood is a sheet material consisting of three or more layers of veneer, which is made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers, with the fiber directions of adjacent veneers glued together perpendicular to each other. Plywood is one of the commonly used materials in furniture making and is one of the three major types of engineered wood products. It is widely used in construction, furniture, decoration, packaging and other industries. In the production process of plywood, veneers need to be layered and glued together according to specific process requirements.
[0003] Currently, most veneer layering is done manually. Although it is possible to use machinery for automatic layering, both manual and automatic layering can only simply stack the veneers one by one. They cannot apply pressure to bond adjacent veneers together. A special process is required to apply pressure later. The operation process is not only complicated, but also wastes time during the transportation of veneers. Therefore, the overall production efficiency of plywood is low. Utility Model Content
[0004] The purpose of this invention is to provide a plywood adding device for plywood production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A plywood adding device, comprising:
[0007] An operating table, wherein a U-shaped frame is fixedly connected between the two sides of the bottom surface of the operating table;
[0008] A placement frame is provided on the top surface of the workbench. There are two placement frames that are hinged to each other, which can close and stick the two single boards together like a book.
[0009] A rotating mechanism, located inside the C-shaped frame, is capable of rotating and merging the two placement frames.
[0010] The pressure mechanism, located between the two placement frames, is able to tightly bond the two veneers together;
[0011] The centering mechanism has two parts, which are respectively set in the placement frame at the corresponding position, and can move the single board in the placement frame to the center.
[0012] Furthermore, the top surface of the operating table is fixedly connected to both sides of an arc-shaped guide rail, the inner bottom surface of the shaped frame is fixedly connected to four corners of a rotating seat, the top of the rotating seat is fixedly connected to a cylinder, the bottom surface of the placement frame is fixedly connected to two rotating seats that are fixedly connected to the output end of the cylinder at the corresponding position, and the side of the placement frame is fixedly connected to a limiting block that slides through the arc-shaped guide rail at the corresponding position.
[0013] Furthermore, the pressure-applying mechanism includes two symmetrical airbags fixedly connected inside the placement frame at corresponding positions. A connecting pipe is fixedly connected between the two airbags. A three-way pipe is fixedly connected to the outer wall of the connecting pipe. An air pump is fixedly connected to the inner bottom surface of the C-shaped frame. The output end of the air pump is fixedly connected to the three-way pipe through an air pipe.
[0014] Furthermore, the connecting pipe is a flexible hose.
[0015] Furthermore, the inner bottom surface of the placement frame is provided with sliding holes on both sides, and the centering mechanism includes four sliders that are slidably connected inside the sliding holes at corresponding positions, and a push plate is fixedly connected between two sliders at opposite positions.
[0016] Furthermore, the bottom surfaces of the placement frame are fixedly connected to two fixed blocks on both sides, and a bidirectional lead screw that is rotatably connected between the two fixed blocks at the same end of the placement frame and screwed through to the two sliders at the corresponding positions.
[0017] Furthermore, a single-groove synchronous pulley is fixedly connected to the outer wall of the bidirectional lead screw, a motor is fixedly connected to the bottom surface of the placement frame, a double-groove synchronous pulley is fixedly connected to the output end of the motor, and a synchronous belt is sleeved between the two grooves of the double-groove synchronous pulley and the two single-groove synchronous pulleys respectively.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. By merging two placement frames, the two veneers can be bonded together under the action of the rotating and pressing mechanisms, thereby achieving the mutual layering of veneers. Moreover, no special pressing process is required in the later stage, reducing the number of steps in plywood production and thus reducing the time for veneer transportation, thereby improving the efficiency of plywood production.
[0020] 2. Driven by the motor, the two bidirectional lead screws at corresponding positions can rotate. The rotation of the two bidirectional lead screws can cause the two push plates at corresponding positions to move closer or further apart. When the two push plates at opposite positions move closer together, they can move the single board at the corresponding position toward the center of the placement frame, thus making it easier for the two single boards to be aligned and glued.

[0028] 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.
[0029] Please see Figure 1 - Figure 6 In this embodiment of the utility model, a plywood production layering device includes an operating table 1. A U-shaped frame 12 is fixedly connected between the two sides of the bottom surface of the operating table 1. Two placement frames 2 are provided on the top surface of the operating table 1 and are hinged to each other, which can close and stick two veneers together like a book. The U-shaped frame 12 is provided with a rotating mechanism that can rotate and merge the two placement frames 2. A pressure mechanism 3 is provided between the two placement frames 2 to tightly stick the two veneers together. The placement frames 2 are provided with a centering mechanism 4 that can move the veneers in the placement frames 2 to the middle.
[0030] Specifically, firstly, two veneers coated with adhesive are placed in corresponding placement frames 2. Then, two centering mechanisms 4 are used to position the two veneers in the center of their respective placement frames 2. A rotating mechanism drives the two placement frames 2 to rotate along their hinges until they are pressed together. Then, a pressure applying mechanism 3 brings the two veneers closer together until they are pressed against each other, and pressure is continuously applied to the veneers, allowing them to be fixed together with adhesive to form a veneer blank. This achieves the layering of veneers. When the two veneers are completely pressed together... After solidification, the two placement frames 2 are returned to their original positions by the rotating mechanism. At this time, the workers can remove the two veneers that are glued together and put the veneers back in. If it is necessary to add another layer on the board blank, the above operation can be followed to add another layer on the board blank. This device can glue the two veneers together by merging the two placement frames 2 and then under the action of the rotating mechanism and the pressure mechanism 3, thereby realizing the mutual layering of veneers. Moreover, no special process for applying pressure is required in the later stage, which reduces the number of steps in plywood production and thus reduces the time for veneers to be transported, thereby improving the efficiency of plywood production.
[0031] Example 1
[0032] like Figure 2 and Figure 3 As shown, in this embodiment, arc-shaped guide rails 11 are fixedly connected to both sides of the top surface of the operating table 1, rotating seats 13 are fixedly connected to the four corners of the inner bottom surface of the shaped frame 12, cylinders 14 are fixedly connected to the top of the rotating seats 13, rotating seats 21 are fixedly connected to the output ends of the cylinders 14 at the corresponding positions on both sides of the bottom surface of the placement frame 2, and limiting blocks 22 that slide through the arc-shaped guide rails 11 at the corresponding positions are fixedly connected to the side of the placement frame 2.
[0033] In this embodiment, the two placement frames 2 can be rotated along the hinge by the driving of two cylinders 14, so that the two placement frames 2 are merged like an open book, so that the single board in the placement frame 2 is perpendicular to the operating table 1, and then the two single boards are tightly pressed together by the pressure mechanism 3.
[0034] Example 2
[0035] like Figure 5 As shown, in this embodiment, the pressure applying mechanism 3 includes two symmetrical airbags 31 fixedly connected inside the placement frame 2 at corresponding positions. A connecting pipe 32 is fixedly connected between the two airbags 31. A three-way pipe 33 is fixedly connected to the outer wall of the connecting pipe 32. An air pump 34 is fixedly connected to the inner bottom surface of the frame 12. The output end of the air pump 34 is fixedly connected to the three-way pipe 33 through an air pipe. The connecting pipe 32 is a flexible hose structure.
[0036] In this embodiment, the air pump 34 can inflate the two airbags 31. After inflation, the volume of the airbags 31 increases. The two airbags 31 with increased volume can clamp the two single boards between the two airbags 31, so that the two airbags 31 tightly stick the two single boards together.
[0037] Example 3
[0038] like Figure 6 As shown, in this embodiment, sliding holes 23 are provided through both sides of the inner bottom surface of the placement frame 2. The centering mechanism 4 includes four sliders 41 that are slidably connected inside the sliding holes 23 at corresponding positions. A push plate 42 is fixedly connected between two sliders 41 at opposite positions. Fixing blocks 24 are fixedly connected to both sides of the bottom surface of the placement frame 2. A bidirectional lead screw 43 that is rotatably connected between two fixing blocks 24 at the same end of the placement frame 2 and is screwed through to two sliders 41 at corresponding positions is rotatably connected. A single-groove synchronous wheel 44 is fixedly connected to the outer wall of the bidirectional lead screw 43. A motor 45 is fixedly connected to the bottom surface of the placement frame 2. A double-groove synchronous wheel 46 is fixedly connected to the output end of the motor 45. A synchronous belt is sleeved between the two grooves of the double-groove synchronous wheel 46 and the two single-groove synchronous wheels 44 respectively.
[0039] In this embodiment, the motor 45 drives the two bidirectional lead screws 43 at corresponding positions to rotate. The rotation of the two bidirectional lead screws 43 causes the two push plates 42 at corresponding positions to move closer or further apart. When the two push plates 42 at opposite positions move closer together, they can move the single board at the corresponding position toward the center of the placement frame 2, thereby facilitating the alignment and bonding of the two single boards.
