Description
Technical Field
[0001] The invention belongs to the technical field of wood processing machinery and relates to a round bar feeding machine. Background Art
[0002] Solid wood integrated board is composed of several strips of square wood, and the strips of square wood are made of round wood sticks through four-sided planing. The processing process of the strips of square wood sticks is to put the round wood sticks into the four-sided planing machine through the loader for planing to obtain square wood sticks. The purchased round wood sticks are usually delivered from the manufacturer in bundles of twenty. At present, there is an automatic stick feeder (application number: 202022064251.X). The workers first untie the bundles of round wood sticks placed on the ground, and then put the round wood sticks one by one or several on the first conveyor belt by hand. The first conveyor belt transports the round wood sticks to the inclined second conveyor belt. The spacers on the second conveyor belt separate the round wood sticks and transport them to the conveying wheel. The conveying wheel then sends the round wood sticks out one by one and puts them into the four-sided planing machine for planing. The existing automatic stick feeder has the following problems during use: 1. Workers need to frequently bend and stand up to put the logs on the first conveyor belt, which results in a large amount of labor; 2. When the logs fall from the first conveyor belt to the inclined second conveyor belt, the logs will accumulate on the second conveyor belt. Although several spacers on the second conveyor belt separate the logs individually, due to the stacking problem, other logs will be stacked between the first log and the second log that fall into the spacer, and the stacked logs will fall out of the machine when they are transported to the end of the second conveyor belt; 3. The logs may sometimes be misaligned during transportation on the second conveyor belt. The left end of the log is between the first and second spacers, while the right end is between the second and third spacers. Finally, the logs cannot fall accurately into the conveying wheel under the second conveyor belt and fall out of the machine; 4. The logs that fall out of the machine need to be picked up by workers and put back on the first conveyor belt, which results in a low efficiency. Summary of the invention
[0003] The invention provides a round rod feeder to solve the problems of large labor force, easy falling of the rods out of the machine and low efficiency in the existing automatic rod feeder.
[0004] In order to solve the above problems, the technical solution adopted by the present invention is: it includes a frame, a loading belt, a dividing roller and a plurality of feeding wheels, the loading belt, the dividing roller and the feeding wheel are installed on the frame, the conveying end of the loading belt extends to one side of the dividing roller, and the plurality of feeding wheels are arranged below the other side of the dividing roller, and a material trough is provided between the loading belt and the dividing roller; a plurality of partitions are arranged at intervals on the loading belt, a plurality of hanging hooks are arranged in parallel at both ends of the dividing roller, and a plurality of material shifting blocks are provided at the two end surfaces of the dividing roller, and the material shifting blocks are located above the opening of the hanging hook, the loading belt conveys a plurality of logs to the material trough, the dividing roller then conveys the logs one by one to the feeding wheel, and the feeding wheel then puts the logs into the four-sided planer.
[0005] In the above technical scheme, a more specific technical scheme can also be: the upper end of the material shifting block is hinged on the end face of the material dividing roller, the lower end of the inward side of the material shifting block is connected to one end of the tension spring, the other end of the tension spring is connected to the end face of the material dividing roller, a limit rod is provided between the upper end of the material shifting block and the tension spring, the inward side of the material shifting block is a concave arc surface, the frame is provided with a push rod extending to the end face of the material dividing roller, the end of the push rod is a convex arc surface, when the material shifting block rotates with the material dividing roller and passes through the push rod, the push rod pushes the material shifting block outward, if two round wooden sticks are hung on the hanging hook, the upper round wooden stick will be pushed out by the material shifting block and fall back into the material trough.
[0006] Furthermore: the feeding belt is arranged at an angle, the conveying starting end of the feeding belt is located at the bottom, and the conveying end of the feeding belt is located at the top, the side of the partition facing the conveying direction is arc-shaped, and the other side of the partition is provided with a support rod. Since the round logs delivered from the manufacturer are bundled in twenty pieces, the heavier bundles of round logs can be directly transported to the conveying starting end of the feeding belt located at the bottom, thereby reducing labor. Since the twenty round logs are heavy, the partition and the round logs are arc-shaped and provided with support rods to prevent them from being compressed and deformed.
[0007] Furthermore: two guide rods are also provided on the frame, one end of the two guide rods is located on both sides of the feeding wheel, and the other end of the two guide rods extends close to the dividing roller, which can increase the accuracy of sending the round logs from the dividing roller to the feeding wheel.
[0008] Furthermore: a push rod is provided at the lower part of the material trough, and the push rod is driven by a cylinder. A push proximity switch extending close to the end face of the material distribution roller is provided on the frame, and the push proximity switch is connected to the cylinder. When the material distribution roller rotates one circle, the push proximity switch senses that the hanging hook passes by, and the cylinder controls the push rod to push the round wooden stick in the material trough.
[0009] Furthermore: the feeding belt is driven by a feeding motor, and a feeding photoelectric switch is provided on the upper part of the material trough, and the feeding photoelectric switch is connected to the feeding motor. When the feeding photoelectric switch senses that there are too many round logs in the material trough, the feeding motor stops driving the feeding belt and suspends conveying round logs to the material trough.
[0010] Furthermore: the material dividing roller is driven by a material dividing motor, and a material dividing photoelectric switch is provided on the upper part of the guide rod, and the material dividing photoelectric switch is connected to the material dividing motor. When the material dividing photoelectric switch senses that there are too many round logs in the two guide rods, the material dividing motor stops driving the material dividing roller and suspends conveying round logs to the feeding wheel. The feeding wheel is driven by the feeding motor.
[0011] Due to the adoption of the above technical scheme, the present invention has the following beneficial effects compared with the prior art: 1. Workers only need to put the bundled logs between the partitions on the feeding belt and then untie the ropes. There is no need to frequently bend down and stand up to carry the logs, which effectively reduces the labor intensity of workers; 2. The hanging hooks on both sides of the dividing roller and the material-shifting blocks above it ensure that the logs are delivered to the feeding wheel one by one, which solves the problem of log stacking and effectively prevents the logs from falling out of the machine; 3. Due to the cylindrical shape of the dividing roller itself, when the left end of the log is hung on the first hanging hook on the left side of the dividing roller, the right end of the log cannot be hung on the second hanging hook on the right side of the dividing roller, which ensures that the log is accurately delivered to the feeding wheel and further prevents the log from falling out of the machine; 4. The logs no longer fall out of the machine, which has the characteristics of high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
