Description

Technical Field

[0001] This utility model relates to the technical field of wood gluing equipment, specifically a gluing machine for a fully automatic tenon-and-mortise jointing machine. Background Technology

[0002] Log grafting machines play a crucial role in the timber processing industry, primarily in the following aspects: Improving timber utilization: By joining short logs together, log grafting machines achieve the goal of using shorter logs for longer periods and using inferior logs for better performance. This is especially important when timber resources are relatively limited, significantly reducing waste and increasing the economic value of timber. Reducing production costs: By using log grafting machines, companies can reduce their demand for long logs and instead utilize more short, lower-cost logs. This not only reduces raw material procurement costs but also minimizes waste and losses from cutting long logs. Promoting the development of the timber processing industry: The widespread application of log grafting machines drives technological progress and industrial upgrading in the timber processing industry. With continuous innovation and improvement in grafting technology, timber processing companies can better meet market demands for long and high-quality timber, enhancing their market competitiveness.

[0003] Before joining timber strips using a splicing machine, the ends need to be grooved and glued. A search revealed Chinese patent application CN202020881291.0, which discloses a glue-applying machine for splicing timber strips. This machine includes a moving mechanism for moving the timber strips, a fixed frame, and the fixed frame mounted on both sides of the moving mechanism. It also includes a fixing mechanism for securing the timber strips and a glue-applying mechanism for applying glue to the timber strips. The fixing mechanism is mounted above the moving mechanism, and the glue-applying mechanism is positioned above the fixing mechanism. This invention, by setting up a fixing mechanism, can stably fix the timber strips, preventing them from shaking during glue application, thus ensuring the glue application effect. By using a glue-applying mechanism, mechanical glue application replaces manual labor, ensuring the health of workers. Furthermore, it can apply glue to two timber strips at a time, thus improving glue application efficiency.

[0004] The above technical solution uses a glue brush to apply glue to the wood. Since multiple sets of tenon grooves with a certain depth are opened at the ends of the wood, the glue brush is difficult to penetrate into the interior of the tenon grooves to achieve complete glue application. This may lead to insufficient glue and low joint strength during subsequent joining. In addition, the above technical solution can only apply glue to a maximum of two wood strips, resulting in low glue application efficiency. Therefore, we need to propose a glue application machine for a fully automatic tenon-jointing wood machine. Utility Model Content

[0005] The purpose of this utility model is to provide a glue applicator for a fully automatic tenon and mortise jointing machine. By using an immersion glue applicator, the glue can penetrate into all the tenon and mortise grooves of the wood strips, ensuring that the glue is even and sufficient at the joint ends of the wood strips. This avoids the problem of insufficient glue leading to low connection strength during subsequent jointing. Moreover, it can apply glue to multiple wood strips simultaneously, improving the efficiency of wood jointing and processing, thereby solving the problems mentioned in the background art.

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1-2 This utility model provides a technical solution:

[0027] A glue applicator for a fully automatic tenon-and-mortise jointing machine includes:

[0028] Abutment 1;

[0029] Support plates 5 are provided on both sides of the bottom of the base 1, and a groove 2 is provided on one side of the base 1. A glue box 3 for storing glue is snapped into the inside of the groove 2.

[0030] It also includes a placement mechanism for placing the slotted timber; the placement structure includes a placement plate 8 and protrusions 6 symmetrically arranged on both sides of the base 1. Support arms 7 are provided on both sides of the placement plate 8, and the lower end of the support arms 7 is provided with a shaft. The support arms 7 are rotatably mounted to the protrusions 6 via the shaft.

[0031] It also includes a fixing assembly for fixing the wood; the fixing assembly includes a U-shaped plate 9 disposed on the placement plate 8, and two sets of cylinders 10 are mounted on the U-shaped plate 9. The piston rod end of the cylinder 10 passes through the U-shaped plate 9 and is connected to a fixing plate 11.

[0032] The placement plate 8 is oscillating towards the glue box 3 via a drive assembly. The drive assembly includes a reciprocating screw 15 and a connecting arm 12. Two sets of drive plates 14 are provided on the outer wall of the support plate 5. The reciprocating screw 15 is rotatably mounted between the two sets of drive plates 14, and a motor 16 for driving the reciprocating screw 15 is mounted on the outer wall of one set of drive plates 14. A slide 17 is mounted on the reciprocating screw 15, and a top plate 18 is provided on the top of the slide 17. A guide groove 19 is provided on the top plate 18. The shaft of one set of support arms 7 passes through the lug and is fixedly connected to the upper end of the connecting arm 12. A guide wheel 13 is rotatably mounted on the lower end of the connecting arm 12 and is slidably mounted inside the guide groove 19.

[0033] In actual use, glue is added to the glue box 3, and multiple wooden strips are placed on the placement plate 8. At this time, when the slide 17 is located at one end of the reciprocating screw 15, the guide wheel 13 is located at the top of the guide groove 19, the placement plate 8 is in a horizontal state, and the cylinder 10 is activated to make the clamping plate clamp the wooden strips.

[0034] When the motor 16 starts, it drives the reciprocating screw 15 to rotate. During the process of the slide 17 moving to the other end of the reciprocating screw 15, the guide wheel 13 first slides to the lower end of the guide groove 19 and then slides to the top end of the guide groove 19. When the slide 17 is at the other end of the reciprocating screw 15, the placement plate 8 rotates the wooden strip into a vertical state.

[0035] At this time, the motor 16 stops working, and the cylinder 10 drives the fixing plate 11 to slightly loosen the wooden strips. The wooden strips can slide down until the lower ends of all the wooden strips (i.e. the ends with tenon grooves) are in contact with the bottom of the glue box 3. At this time, the glue in the glue box 3 can fully penetrate into the interior of the tenon groove, thereby achieving the purpose of applying glue evenly to the joint end of the wooden strips.

[0036] After the wood strip ends are coated with glue, the cylinder 10 drives the fixing plate 11 to clamp the wood strip again, the motor 16 works again and the slide 17 returns to the initial end, thereby driving the placement plate 8 back to the horizontal state, the cylinder 10 resets, and the glued wood strip can be removed to proceed with the next batch of wood to be glued.

[0037] In summary, this device has a simple structure and is easy to use. Through immersion gluing, the glue can penetrate into all the tenon and mortise grooves of the wooden strips, ensuring that the glue is even and sufficient at the joint ends of the wooden strips. This avoids the problem of insufficient glue leading to low connection strength during subsequent jointing. Moreover, it can apply glue to multiple wooden strips at the same time, improving the efficiency of wood joining and processing.

[0038] For further details, please refer to Figure 3 :

[0039] It also includes a heating component disposed at the bottom of the groove 2. The heating component includes an insulating rod 20 and an electric heating wire 21. Multiple sets of insulating rods 20 are distributed at the bottom of the groove 2. The electric heating wire 21 is wound on the insulating rod 20. A grid plate is disposed on the inner wall of the groove 2 above the heating component.

[0040] By setting a heating assembly including an insulating rod 20 and an electric heating wire 21 in the groove 2, the glue in the glue box 3 can be kept warm and heated during the use of the equipment, so as to maintain the fluidity of the glue and facilitate the glue application process on the wood strips.

[0041] In addition, please see Figure 3 :

[0042] The glue box 3 has side edges 4 on both sides of the top opening, and rubber strips 22 are provided on both sides of the base 1 located in the groove 2. When the glue box 3 is inserted into the groove 2, the bottom of the side edge 4 abuts against the top of the rubber strip 22.

[0043] When the wooden strip slides down and is immersed in the glue box 3, it will cause a certain impact on the glue box 3. The design of the rubber strip 22 can buffer this impact force to a certain extent, prevent the glue box 3 from being easily damaged, and thus extend the service life of the glue box 3.

[0044] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
