Description

Technical Field

[0001] The utility model relates to a field, in particular to a material conveying mechanism for a laser 3D printing device. Background Technique

[0002] 3D printing, also known as additive manufacturing technology, is a technology for manufacturing solid parts by the method of layer-by-layer material accumulation based on three-dimensional CAD data. The historical development of 3D printing technology is a process of continuous progress and expansion. From the early rapid prototyping technology to the current wide application, 3D printing technology has been applied in design and manufacturing fields such as jewelry design, shoe design and manufacturing, industrial design, architectural design, engineering design and construction, automotive design and manufacturing, as well as medical fields such as aerospace and dentistry.

[0003] Patent No. CN208514980U discloses a material conveying mechanism for a laser 3D printing device, including a box body. A feed pipe is arranged on the left side of the box body. A conveying mechanism is arranged on the left side of the inner cavity of the box body. The conveying mechanism includes a number of conveying roller support columns. A conveying roller is arranged between two conveying roller support columns. Both sides of the conveying roller are movably connected with the conveying roller support columns through conveying roller shafts. A conveyor belt is sleeved outside the conveying roller. One end of the conveying roller shaft is fixedly installed with a worm gear. A worm is meshed on one side of the worm gear. For this material conveying mechanism of the laser 3D printing device, by setting a guiding roller and a driven roller to cooperate with a guiding groove, the printing consumables will not move left and right during the conveying process, so that the feeding is accurate. By setting a roller shaft support plate to cooperate with a spring, the driven roller is elastic. For flexible printing materials, it can well provide a feeding force to complete a stable feeding process and make the feeding process normal.

[0004] When the above device is in use, when conveying the printing consumables, the printing consumables are prone to break away from the guiding groove, resulting in the accumulation of consumables inside the box body, and the friction force of the conveyor belt on the consumables is insufficient, affecting the transportation efficiency of the consumables. Content of the Utility Model

[0005] The purpose of the utility model is to provide a material conveying mechanism for a laser 3D printing device to solve the problems that when conveying the printing consumables, the printing consumables are prone to break away from the guiding groove, resulting in the accumulation of consumables inside the box body, and the friction force of the conveyor belt on the consumables is insufficient, affecting the transportation efficiency of the consumables.

[0006] To achieve the above object, the present utility model provides the following technical solution: A material conveying mechanism for a laser D printing device, comprising a box body. Below the interior of the box body, a first support frame is fixedly connected. Above the first support frame, a conveyor belt is installed.

On one side of the first mounting plate, a fixed rod is fixedly connected. One end of the fixed rod is fixedly connected to a first mounting frame. Inside the first mounting frame, a first rotating roller is rotatably connected. Above the first mounting plate, a connecting frame is fixedly connected. When the printing consumables are placed above the conveyor belt, the telescopic cylinder is started. By the telescopic cylinder pushing the first mounting plate to move, the first rotating roller contacts the consumables, thereby fixing the consumables and preventing the consumables from separating from the material guiding groove and accumulating inside the box body.

A spring is sleeved on the outer surface of the telescopic rod. One end of the second mounting plate is rotatably connected to a connecting plate. One end of the connecting plate is rotatably connected to one side of the connecting frame. When the telescopic cylinder pushes the first rotating roller to fix the consumables, the connecting plate pushes the second mounting plate to slide in the chute, thereby pushing the second driving roller downward to increase the friction force and prevent the conveyance of the consumables from being affected due to insufficient friction force.

[0008] As a further scheme of the present utility model: Below the interior of the box body, a second support frame is fixedly connected. On one side of the second support frame, a second motor is installed. The output end of the second motor is fixedly connected to a material guiding roller. On one side of the interior of the box body, a third support frame is fixedly connected. Inside the third support frame, a driven roller that cooperates with the material guiding roller is rotatably connected. Start the second motor to drive the material guiding roller to rotate. The material guiding roller drives the driven roller to rotate. Through the cooperation of the material guiding roller and the driven roller, the consumables are transported to the discharge pipe.

[0009] As a further scheme of the present utility model: Above the box body, a first motor is installed. On one side of the first support frame, a worm gear is rotatably connected. One side of the worm gear is fixedly connected to one end of the driving roller inside the conveyor belt. The output end of the first motor is fixedly connected to a worm that meshes with the worm gear. Through the cooperation of the worm gear and the worm, the conveyor belt runs more stably.

[0010] As a further scheme of the present utility model: On one side of the box body, a feed pipe is provided. The feed pipe is flush with the conveyor belt. The consumables are placed above the conveyor belt through the feed pipe.

[0011] As a further solution of the present utility model: a discharge pipe is provided on one side of the box body, and the discharge pipe is flush with the gap between the material guiding roller and the driven roller, and the consumables transported by the material guiding roller are transported out through the discharge pipe.

[0012] As a further solution of the present utility model: a material guiding groove is provided on the upper surface of the conveyor belt, and the consumables are preliminarily fixed through the material guiding groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. By providing the first rotating roller, when the printing consumables are placed above the conveyor belt, the telescopic cylinder is started, and the first mounting plate is pushed to move through the telescopic cylinder, so that the first rotating roller contacts the consumables, thereby fixing the consumables and preventing the consumables from detaching from the material guiding groove and accumulating inside the box body;

[0015] 2. By providing the second driving roller, when the telescopic cylinder pushes the first rotating roller to fix the consumables, the connecting plate pushes the second mounting plate to slide in the sliding groove, thereby pushing the second driving roller downward, which can increase the friction force and prevent the transmission of the consumables from being affected due to insufficient friction force.
