Description

Technical Field

[0001] This utility model relates to the field of wood-plastic pallet production technology, and in particular to a glue-applying device for wood-plastic pallet production. Background Technology

[0002] An existing glue-applying device for wood-plastic pallet production, with publication number CN 217856842 U, uses a support base and a push plate. A third electric telescopic rod pushes the pallet in the loading frame upwards, followed by a first electric telescopic rod pushing the top pallet to the right. Simultaneously, a second electric telescopic rod pushes a piston downwards, allowing glue from the glue-applying cylinder to be injected into the pallet surface. After glue application, the first electric telescopic rod returns to its original position. When the first electric telescopic rod continues to push another pallet to the left for glue application, the glue-applied pallet on the rollers can be pushed out from under the glue-applying head. This method allows for glue application to the pallet during movement, and the finished pallet automatically detaches from under the glue-applying head, thus improving glue application efficiency. However, after the pallet passes under the glue-applying head, the glue is applied in a thick, elongated strip, and the glue is not evenly spread. This can cause uneven glue application during subsequent bonding, affecting the bonding effect. Utility Model Content

[0003] The purpose of this invention is to provide a glue application device for the production of wood-plastic pallets in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A glue-applying device for wood-plastic pallet production includes a workbench with a lifting component and a pushing component. A mounting frame is located on one side of the pushing component on the workbench, and a glue-injection component is mounted on the mounting frame. The device also includes a spreading mechanism located on one side of the pushing component for evenly spreading the glue on the pallet after injection. The spreading mechanism includes a lifting component fixed to the mounting frame, a damping telescopic rod fixed to the lower end of the lifting component, a support frame at the lower end of the damping telescopic rod, a reciprocating moving component mounted on the lower side of the support frame, a rotating shaft mounted on the lower side of the reciprocating moving component, and a spreading wheel mounted on the rotating shaft. The reciprocating moving component includes a reciprocating screw and a guide column arranged horizontally parallel to each other on the support frame, a moving frame mounted on the reciprocating screw and guide column, a geared motor connected to one end of the reciprocating screw, and a power component for providing rotational power to the rotating shaft mounted on the moving frame.

[0006] Further configuration: The lifting assembly includes an electric telescopic rod vertically fixed on the mounting frame, with sliding columns on the front and rear sides of the electric telescopic rod, and a lifting plate fixed to the lower end of the electric telescopic rod and the sliding columns. Damping telescopic rods are spaced apart at the lower end of the lifting plate, and the sliding columns are slidably connected to the mounting frame.

[0007] Further configuration: The reciprocating screw is rotatably connected to the support frame, the movable frame is threadedly connected to the reciprocating screw, and the movable frame is slidably connected to the guide column.

[0009] Further configuration: The secondary gear is located in the middle of the rotating shaft, meshes with the main gear and rotates, and the transmission shaft, worm gear and moving frame are rotatably connected.

[0010] Further features: The outer diameter of the shaft is provided with a threaded groove, and nuts are provided on both sides of the coating wheel to lock and fix the position of the coating wheel.

[0011] Further setting: The direction of the rotation tangent on the lower side of the coating wheel is opposite to the direction of the tray's push.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By setting up a coating mechanism, the lifting component drives the reciprocating moving component connected by the damping telescopic rod to adjust the height.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5As shown, a glue application device for wood-plastic pallet production includes a workbench 1, a lifting component 21 and a pushing component 22 on the workbench 1, a mounting frame 31 on one side of the pushing component 22 on the workbench 1, a glue injection component 32 on the mounting frame 31, and a coating mechanism for spreading the glue evenly on the pallet after glue injection, which is located on one side of the pushing component 22.

[0026] In this embodiment, the coating mechanism includes a lifting assembly fixed on the mounting frame 31. A damping telescopic rod 44 is fixed to the lower end of the lifting assembly. A support frame 45 is provided at the lower end of the damping telescopic rod 44. A reciprocating moving assembly is installed on the lower side of the support frame 45. A rotating shaft 410 is installed on the lower side of the reciprocating moving assembly. A coating wheel 411 is installed on the rotating shaft 410. A threaded groove is provided on the outer diameter of the rotating shaft 410. Nuts are provided on both sides of the coating wheel 411 to lock and fix the position of the coating wheel 411. The position of the coating wheel 411 on the rotating shaft 410 can be adjusted and fixed by the nuts. The rotation tangent direction of the lower side of the coating wheel 411 is opposite to the pushing direction of the tray, so that the coating wheel 411 forms a mutual reaction force on the tray during the pushing process, preventing the tray from being pushed outward.

[0027] The lifting assembly includes an electric telescopic rod 41 vertically fixed on the mounting frame 31. Sliding columns 42 are provided on the front and rear sides of the electric telescopic rod 41. A lifting plate 43 is fixed at the lower end of the electric telescopic rod 41 and the sliding columns 42. Damping telescopic rods 44 are arranged at intervals at the lower end of the lifting plate 43. The sliding columns 42 are slidably connected to the mounting frame 31. The height position of the lifting plate 43 and the support frame 45 is controlled by the extension and retraction of the electric telescopic rod 41, so that the height of the coating wheel 411 on the lower side and the working surface on the workbench 1 is slightly greater than the thickness of the tray.

[0028] The reciprocating moving assembly includes a reciprocating screw 46 and a guide post 47 arranged horizontally and parallel to each other on the support frame 45. A moving frame 48 is provided on the reciprocating screw 46 and the guide post 47. One end of the reciprocating screw 46 is connected to a geared motor 49. The moving frame 48 is provided with a power component for providing rotational power to the rotating shaft 410. The reciprocating screw 46 is rotatably connected to the support frame 45, the moving frame 48 is threadedly connected to the reciprocating screw 46, and the moving frame 48 is slidably connected to the guide post 47. The reciprocating screw 46 is rotated by the operation of the geared motor 49, which pushes the moving frame 48 to reciprocate under the limit of the guide post 47.

[0029] The power assembly includes a drive shaft 413 mounted on the lower side of the movable frame 48. A main gear 414 and a worm gear 415 are fixedly mounted on the drive shaft 413. A worm 416 meshes with the upper side of the worm gear 415. One end of the worm 416 is connected to a servo motor 417. A secondary gear 412 is located on the rotating shaft 410 below the main gear 414. The secondary gear 412 is located in the middle of the rotating shaft 410. The secondary gear 412 meshes with the main gear 414 and rotates. The drive shaft 413, the worm 416 and the movable frame 48 are rotatably connected. The servo motor 417 drives the worm 416 to rotate. The worm 416 meshes with the worm gear 415 and drives the main gear 414 on the drive shaft 413 to rotate. The main gear 414 meshes with the secondary gear 412 on the rotating shaft 410 and rotates, driving the coating wheel 411 to rotate, so that the coating wheel 411 flattens the glue strip on the tray.

[0030] The working principle and usage process of this utility model are as follows: First, adjust the position of the coating wheel 411 on the rotating shaft 410 so that the coating wheel 411 corresponds to the glue application position on the tray. The electric telescopic rod 41 extends and pushes the lifting plate 43 to move downward under the support of the sliding column 42, so that the height of the coating wheel 411 and the working surface on the worktable 1 is slightly greater than the thickness of the tray. The servo motor 417 drives the worm gear 416 to rotate. The worm gear 416 meshes with the worm wheel 415 to drive the main gear 414 on the transmission shaft 413 to rotate. The main gear 414 meshes with the secondary gear 412 on the rotating shaft 410 to rotate, driving the coating wheel 411 to rotate. After the material pushing component 22 pushes the tray past the glue injection component 32 for glue injection, when it moves to the lower side of the coating mechanism, the reduction motor 49 works to drive the reciprocating screw 46 to rotate, so that the reciprocating screw 46 pushes the moving frame 48 to move back and forth under the limit of the guide column 47, so that the coating wheel 411 spreads and coats the glue injection strip on the tray.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
