Description

Technical Field

[0001] The utility model relates to the technical field of glue applicators, and particularly relates to a blanking structure of a glue applicator. Background Art

[0002] A glue applicator is also known as a coating machine, a spreading machine, an automatic glue spraying machine, etc. It is mainly a mechanical device used to apply liquid glue on the surface of textiles, paper boxes or leather. There are many types of existing glue applicators, such as: drum type glue applicator, double-acting glue applicator, double-station lifting glue applicator, etc.

[0003] During the wood processing process, some wooden boards are cut into thin slices and then the glue applicator is used to roll and apply glue to make multiple wooden boards adhere to each other. The existing thin wooden board glue applicator is a two-roll type glue application. The wooden slices pass through two glue application rollers, and the glue application rollers are provided with glue. Although this design can apply glue more evenly, in the traditional two-roll glue applicator, both rolls are fixedly installed and cannot be adjusted in real time according to the thickness of the wooden slices. If adjustment is required, it is necessary to measure the average thickness of the wooden slices and then disassemble the glue application rollers for change, which is rather cumbersome. Summary of the Utility Model

[0004] In order to solve the above technical problems, an embodiment of the utility model provides a blanking structure of a glue applicator, which includes a workbench. A glue dropping port is opened on the workbench, and a fixed glue application roller is rotatably installed on the top of the workbench; a support plate is fixed on the top of the workbench, and a cylinder is fixed on the support plate. The power end of the cylinder penetrates through the support plate and is connected and fixed with a moving frame. The moving frame can move vertically through the cylinder; a buffer mechanism is further included. The buffer mechanism is installed on the moving frame, and a movable glue application roller is installed on the buffer mechanism. The buffer mechanism is used for buffering and anti-collision.

[0005] Further, the buffer mechanism includes a movable plate and a spring. The movable glue application roller is rotatably installed on the movable plate. Sliding columns are respectively fixed at both ends of the moving frame. The movable plate is sleeved on the sliding columns, and the movable plate is slidably connected with the sliding columns. The spring is sleeved outside the sliding columns, and the spring is respectively connected with the movable plate and the moving frame.

[0006] Further, a pair of guide rods are fixed on the top of the moving frame. The two guide rods are symmetrically arranged and are respectively located on both sides of the cylinder. The guide rods penetrate through the support plate and are slidably connected with the support plate.

[0007] Further, a pair of L-shaped plates are fixed at the bottom of the workbench. A glue receiving plate is erected between the two L-shaped plates. The glue receiving plate is located below the glue dropping port.

[0008] Further, a material guiding plate is fixed on the support plate. The material guiding plate is inclined, and a plurality of uniformly distributed ventilation holes are formed in the material guiding plate.

[0009] Further, an extension plate is fixed on one side of the material guiding plate close to the movable glue applicator roller.

[0010] Further, the movable plate is in the shape.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] By arranging the air cylinder, the moving frame, the movable glue applicator roller and the fixed glue applicator roller, the distance between the movable glue applicator roller and the fixed glue applicator roller can be adjusted by the air cylinder, so that it is beneficial for the device to be adjusted according to wood chips of different thicknesses.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0019] As Figures 1-3 , this embodiment provides a blanking structure of a glue applicator, including a workbench 1, a glue dropping port 2 is opened on the workbench 1, a fixed glue applicator roller 4 is rotatably installed on the top of the workbench 1, and a motor assembly for driving the fixed glue applicator roller 4 is provided on one of the two plates where the fixed glue applicator roller 4 is installed. Driving the fixed glue applicator roller 4 by the motor assembly can displace the wood chips, thereby realizing automatic gluing; a support plate 6 is fixed on the top of the workbench 1, a cylinder 7 is fixed on the support plate 6, the power end of the cylinder 7 penetrates the support plate 6, and is connected and fixed with a moving frame 9. The moving frame 9 can move vertically through the cylinder 7; a buffer mechanism is further included, the buffer mechanism is installed on the moving frame 9, and a movable glue applicator roller 5 is installed on the buffer mechanism, and the buffer mechanism is used for buffering and anti-collision.

[0020] The buffer mechanism includes a movable plate 10 and a spring 12. The movable plate 10 is in the shape of , the movable glue applicator roller 5 is rotatably installed on the movable plate 10. Sliding columns 11 are respectively fixed at both ends of the moving frame 9. The movable plate 10 is sleeved on the sliding columns 11, and the movable plate 10 is slidably connected with the sliding columns 11. The spring 12 is sleeved outside the sliding columns 11, and the spring 12 is respectively connected with the movable plate 10 and the moving frame 9. When in use, start the cylinder 7 to move the movable glue applicator roller 5 downward. When the movable glue applicator roller 5 presses against the wood chips, at this time, the movable glue applicator roller 5 will move upward due to the reaction force, thereby compressing the spring 12. At this time, stop the cylinder 7, and start the motor assembly connected to the fixed glue applicator roller 4 to carry out the gluing work. The fixed glue applicator roller 4 slowly rolls and then drags the wood chips, and the wood chips will drag the movable glue applicator roller 5, thereby applying the glue on the wood chips. And, while the two rollers are rotating, the wood chips will gradually displace and then move out away from the two glue applicator rollers, thereby realizing blanking and facilitating use.

[0021] In this embodiment, as Figure 1 and Figure 2 shown, a pair of guide rods 8 are fixed on the top of the moving frame 9. The two guide rods 8 are symmetrically arranged, on both sides of the cylinder 7 respectively. The guide rods 8 penetrate the support plate 6 and are slidably connected with the support plate 6. The two guide rods 8 play a role of supporting and limiting, enabling the moving frame 9 to move smoothly and preventing shaking.

[0022] In this embodiment, as Figure 1 andFigure 3 As shown, a pair of L-shaped plates 16 are fixed to the bottom of the workbench 1. The glue receiving plate 3 is arranged between the two L-shaped plates 16. The glue receiving plate 3 is located below the glue dropping port 2. The glue receiving plate 3 can receive the glue dripping from the fixed glue applying roller 4 and the movable glue applying roller 5, which is convenient for cleaning and keeping the workbench surface tidy.

[0023] In this embodiment, as Figure 2 shown, a material guiding plate 13 is fixed to the support plate 6. The material guiding plate 13 is inclined. The material guiding plate 13 facilitates the blanking of the wood chips after glue application. A plurality of uniformly distributed ventilation holes 14 are formed in the material guiding plate 13. The ventilation holes 14 facilitate ventilation, so that the glue on the wood chips is initially air-dried. An extension plate 15 is fixed to the side of the material guiding plate 13 close to the movable glue applying roller 5. One end of the extension plate 15 is close to the top end of the fixed glue applying roller 4, and can receive the removed template to prevent it from falling.

[0024] The implementation principle of the blanking structure of a glue applicator in an embodiment of this application is as follows: during use, start the cylinder 7 to move the movable glue applying roller 5 downward. When the movable glue applying roller 5 presses against the wood chip, at this time, the movable glue applying roller 5 will move upward due to the reaction force, and then compress the spring 12. At this time, stop the cylinder 7, and start the motor assembly connected to the fixed glue applying roller 4 to perform the glue application work. The fixed glue applying roller 4 slowly rotates to drag the wood chip, and the wood chip will drag the movable glue applying roller 5, so that the glue is applied to the wood chip. Moreover, while the two rollers are rotating, the wood chip will gradually displace and then move out away from the two glue applying rollers, thereby realizing blanking and being convenient to use.
