LED filament baking and cutting machine

Abstract

The present invention discloses an integrated LED filament baking and cutting machine, which relates to the field of filament production technology. By driving a cylinder, a moving block is driven to move along the direction of a guide rod. When the moving block moves, the middle section of the rotating telescopic connecting rod is rotatably arranged on a fixed bracket. The elasticity of the rotating telescopic connecting rod allows the rotating telescopic connecting rod to rotate, thereby driving the height position of the internal driving motor to change accordingly. The internal driving motor drives the cutting knife to rotate, and the cutting knife cuts the filament placed on the positioning frame. Two drying panels are fixedly provided inside the main body, and a conveyor belt is provided under each drying panel. A side door is rotatably provided on the side wall of the integrated machine body. When the cut filament falls from the sliding unloading frame, it first falls onto the first conveyor belt and is transmitted by the drying panel, thereby realizing an integrated single-process operation and reducing processing time.

Description

Technical Field

[0001] The invention relates to the technical field of filament production, and in particular to an LED filament baking and cutting integrated machine. Background Art

[0002] LED filaments are also called LED lamp posts. In the past, in order to achieve a certain illuminance and illumination area, LED light sources needed to be equipped with optical devices such as lenses, which affected the lighting effect and reduced the energy-saving effect of LEDs. LED filaments can emit light at all angles of 360°. They can emit light at large angles without the need for lenses, realizing a three-dimensional light source and bringing an unprecedented lighting experience.

[0003] A search revealed a movable baking device [Patent No.: ZL201110075977.6; Authorization Announcement No.: CN102687735A]. This movable baking device comprises a housing, a conveyor belt, a bracket, and an electronic control device. The housing is fixed to the bracket, and a drying tunnel is defined within the housing. The inner wall of the drying tunnel is provided with multiple heating wires. The upper portion of the conveyor belt is positioned within the drying tunnel, while the lower portion is positioned outside the tunnel. A transmission mechanism is sleeved on both ends of the conveyor belt, and the transmission mechanism is electrically connected to the electronic control device. Universal casters with locking devices are provided at the bottom of the bracket. The device is characterized by feed ports located at the top of the bracket and the left end of the conveyor belt.

[0004] It has certain defects:

[0005] 1. Since the baking length direction is fixed, the filaments are all set in the same direction on the transmission mechanism and cannot be baked from the reverse side, resulting in uneven baking;

[0006] 2. Since the filament needs to be cut to ensure the use requirements, the transmission machine is a multi-process operation, and single-process integrated work is not achieved, the work efficiency is low, and the fixed length corresponding component structure during cutting is complex. Summary of the Invention

At the same time, the middle section of the rotating telescopic connecting rod is rotatably provided on the fixed bracket. The elasticity of the rotating telescopic connecting rod allows the rotating telescopic connecting rod to rotate, thereby driving the height position of the internal driving motor to change accordingly. The internal driving motor drives the cutting knife to rotate, and the cutting knife cuts the filament placed on the positioning frame;

[0010] A lower fixed connection block is fixedly provided on the bottom surface of the cutting component hopper, and the lower fixed connection block is adapted to the guide support rod, and the lower positioning panel is used to position the cutting component hopper and play a role in driving displacement;

[0011] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure is, for example, that two guide wheels are connected along the longitudinal direction of the sliding panel, and the guide wheels are connected along the interlocking structure to form a round rotatable plate.

[0013] As a further solution of the present invention: a plurality of holes are opened on the surface of the lower positioning panel, and the size of the holes is adapted to the position of the end of the positioning block, so that the end of the positioning block can limit its position and realize displacement action.

[0014] As a further solution of the present invention: a guide hole groove is opened on the surface of the fixed bracket, and the guide hole groove is adapted to the guide rod, so that the moving block moves along the direction of the guide rod through the hole groove.
