Description

Technical Field

[0001] This utility model belongs to the field of wood processing technology, and in particular relates to a wood gluing machine for uniformly applying glue. 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 grain direction of adjacent veneers perpendicular to each other. 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. In the production of plywood, glue application equipment is required.

[0003] Currently, wood coating operations are generally carried out manually. Workers place the wood to be coated onto the coating machine and then manually push the wood to apply the glue. However, this coating method has some problems. Because the material is pushed manually, the feeding speed is difficult to control precisely, resulting in uneven coating thickness on the wood surface. In addition, excess coating needs to be processed separately to smooth it out, thus reducing the production efficiency of wood. Utility Model Content

[0005] This utility model is implemented as follows: a wood glue applicator for uniform glue application includes an operating table; support frames are installed on both the left and right sides of the operating table, and rotating rollers are rotatably installed at both the front and rear ends of the operating table. A conveyor belt is installed between two sets of rotating rollers. A motor is installed on the side of the support frame, and the output shaft of the motor is connected to the central shaft of one set of rotating rollers. A fixed frame is installed at the top of the operating table, a paint tank is installed at the top of the fixed frame, a material conveying pipe is installed at the bottom of the paint tank, and the other end of the material conveying pipe is connected to a spray frame. A first electric cylinder is installed on the inner side of the top of the fixed frame, a connecting frame is installed on the output shaft of the first electric cylinder, a first scraper is installed at the bottom of the connecting frame, the connecting frame is configured as an inverted L-shape and the horizontal plate is connected to the side of the spray frame, and the material conveying pipe is configured as a retractable corrugated pipe.

[0011] Compared with the prior art, the embodiments of this application have the following main advantages:

[0012] This device uses a conveyor belt to transport wooden boards at a uniform speed, allowing paint to be sprayed evenly onto the surface of the boards. After spraying, the boards pass over a first scraper. As the boards continue to move at a uniform speed, the first scraper smooths the paint on the surface and removes excess paint, resulting in a smooth and even paint finish. A collection bin and a second scraper are also included. As the conveyor belt continues to move, any paint that falls onto the surface is scraped off by the second scraper and collected in the collection bin. A fan and air ducts are used to blow air and remove dust from the boards, thereby improving the subsequent coating effect. Attached Figure Description

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model provides a wood glue applicator for uniform glue application, such as... Figure 1-4 As shown, the device includes an operating platform 1, with support frames 2 installed on both the left and right sides. Rotary rollers 3 are rotatably mounted at both the front and rear ends of the operating platform 1. A conveyor belt 4 is installed between the two sets of rollers 3. A motor 5 is mounted on the side of the support frame 2, and the output shaft of the motor 5 is connected to the central shaft of one set of rollers 3. A fixed frame 6 is installed at the top of the operating platform 1, a paint tank 7 is installed on the top of the fixed frame 6, and a material conveying pipe 8 is installed at the bottom of the paint tank 7. The other end of the material conveying pipe 8 is connected to a spray frame 9. A first electric cylinder 12 is installed on the inner side of the top of the fixed frame 6, and a connecting frame 10 is installed on the output shaft of the first electric cylinder 12. A first scraper 11 is installed at the bottom of the connecting frame 10. The connecting frame 10 is configured as an inverted L-shape, and its horizontal plate is connected to the side of the spray frame 9. The material conveying pipe 8 is a retractable corrugated pipe. When this device is in use… The wood board to be coated can be placed on the conveyor belt 4, and then the motor 5 is started. The motor 5 drives the rotating roller 3 to rotate, so that the conveyor belt 4 can be transported at a uniform speed. The wood board is transported by the conveyor belt 4 to the bottom of the spray frame 9 for spraying. After spraying, the wood board will pass through the first scraper 11. As the wood board is transported at a uniform speed, the first scraper 11 will scrape the coating on the surface of the wood board and remove the excess coating, so that the coating on the surface of the wood board is flat and uniform. By setting the first electric cylinder 12, the height of the first scraper 11 can be adjusted after the first electric cylinder 12 is started, so as to facilitate the adjustment of the coating thickness on the surface of the wood board. The spray frame 9 is installed through the corrugated material conveying pipe 8 and can move up and down with the connecting frame 10. This setting allows the spray frame 9 to be close to the wood board for spraying, avoiding the problem of the coating being scattered due to the distance being too far.

[0021] The front side of the first scraper 11 is set as an inclined surface and is installed at an angle on the bottom of the connecting frame 10. By setting the front side of the first scraper 11 as an inclined surface, paint can be prevented from accumulating on the top of the first scraper 11. By installing the first scraper 11 at an angle, the scraped paint can be guided to one side to flow down, preventing the scraped paint from accumulating on the surface of the wood board.

[0022] Barrier strips 13 are installed on both sides of the conveyor belt 4. A recycling bin 14 is installed at the bottom of the support frame 2. A second scraper 15 is installed on the top of the recycling bin 14. The second scraper 15 is in contact with the surface of the conveyor belt 4. By setting the barrier strips 13, the barrier strips 13 can prevent the scraped paint from leaking out from both sides of the conveyor belt 4. By setting the recycling bin 14 and the second scraper 15, as the conveyor belt 4 continues to transport, the paint falling on the surface of the conveyor belt 4 will be scraped off by the second scraper 15 and flow into the recycling bin 14 for collection.

[0023] A second electric cylinder 16 is installed on both the left and right sides of the fixed frame 6. The output shafts of the two sets of second electric cylinders 16 are connected to positioning plates 17. By setting the positioning plates 17, the position of the positioning plates 17 can be adjusted by the second electric cylinders 16, thereby positioning the initial position of the wooden board and straightening it.

[0024] A fan 18 is installed on the top of the fixed frame 6. The air outlet of the fan 18 is connected to an air duct, and an air duct 19 is installed at the other end of the air duct. The air duct 19 is fixed at an angle to the front opening of the fixed frame 6. By setting up the fan 18, the fan 18 draws in air and enters the air duct 19 through the air duct. Then it blows out from the front of the air duct 19, which can remove dust from the surface of the wood board and improve the effect of subsequent coating.

[0025] Spray nozzles are installed at equal intervals on the lower side of the spray frame 9. Solenoid valves 20, each corresponding to a spray nozzle, are installed at equal intervals on the surface of the spray frame 9. Each spray nozzle and solenoid valve 20 can be opened and closed independently. This setting allows for adjustment of the spray width, making it easier to spray wood boards of different widths and preventing paint from being sprayed directly onto the conveyor belt 4 on both sides.
