Abstract
Description
Technical Field
[0001] The invention relates to the technical field of conveying equipment, and in particular to an interval feeding mechanism used in an automated production line for solid wood processing. Background Art
[0002] In the automated production line for solid wood processing, the interval feeding mechanism is the key equipment to achieve efficient material distribution. Currently, the interval feeding solutions commonly used in the industry mainly include the following two types of technologies: The first solution uses a motor-driven chain transmission structure to continuously push wood through chain accessories and complete a 90-degree flip. Its technical defects are that the spacing of the chain accessories is fixed and can only match the width of a single specification of wood. When changing products, the mechanical structure needs to be readjusted, resulting in insufficient flexibility of the production line; the continuous operation of the motor makes it impossible to accurately adjust the feeding interval time, making it difficult to achieve dynamic synchronization with the downstream process, affecting the overall production efficiency.
[0003] The second solution is to achieve material separation through a reciprocating swinging claw mechanism, using double claws to alternately block and release the wood. Although the beat problem caused by continuous motion has been solved, there are still significant limitations. The claw spacing is a fixed design and is only suitable for wood of a specific width. When the process changes, the machine needs to be stopped to replace parts, resulting in a decrease in equipment utilization; mechanical claws are prone to rigid collision with wood under high-speed conditions, resulting in scratches on the wood surface or increased wear of the mechanism.
[0004] The above existing technologies all have the core problems of strong dependence on rigid dimensions and lack of compatibility with multiple specifications. With the growing market demand for customized furniture, there is an urgent need for an adaptive interval feeding device that can quickly adapt to different wood widths to improve the flexibility of the production line and reduce the cost of equipment modification. Summary of the invention
[0005] The purpose of the present invention is to provide an interval feeding mechanism for an automated production line for solid wood processing, so as to solve the problem that the prior art cannot adapt to wood of various specifications.
[0006] The present invention is implemented by adopting the following technical scheme: an interval feeding mechanism for an automated production line for solid wood processing, comprising a conveyor belt, characterized in that it comprises a material blocking component and a material dividing component, the material blocking component and the material dividing component are arranged on a conveyor belt device, the material blocking component is driven to rise and fall by a telescopic device, and when the material blocking component rises, the material on the conveyor belt is blocked, the material dividing component and the material blocking component are driven in linkage through the telescopic device, the telescopic device drives the material blocking component to rise and causes the material dividing component to fall, and the telescopic device drives the material blocking component to fall and causes the material dividing component to rise, and when the material dividing component rises, the front and rear adjacent materials on the conveyor belt are separated, thereby realizing interval conveying.
[0007] Further, the material blocking assembly includes a material blocking rod, one end of the material blocking rod is provided with a blocking member, the material blocking rod is fixed on a rotating shaft, the telescopic device is rotatably connected with a connecting rod and is connected with the rotating shaft through the connecting rod, the connecting rod is fixedly connected with the rotating shaft, and the telescopic device drives the rotating shaft to rotate through telescopic movement, thereby driving the material blocking rod to rotate, so that the blocking member arranged at one end of the material blocking rod rises and falls. Further, the material distributing assembly includes a horizontal connecting rod, an adjusting block is arranged on the horizontal connecting rod, the adjusting block is higher than the horizontal connecting rod, when the horizontal connecting rod rises, the adjusting block lifts the materials on the conveyor belt and at the same time blocks the materials at the rear to realize material distribution.
[0008] Further, the horizontal connecting rod is rotatably connected with one end of the material blocking rod, both ends of the material blocking rod are respectively connected with the blocking member and the horizontal connecting rod, and the rotating shaft is connected between the blocking member and the horizontal connecting rod; The material blocking rod forms a lever structure with the rotating shaft as the fulcrum, so that the telescopic device drives the rotating shaft to rotate forward and backward, thereby realizing the alternating rising and falling of the blocking member and the horizontal connecting rod.
[0009] Further, the adjusting block is slidably connected with the horizontal connecting rod, a sliding track is arranged on the horizontal connecting rod, and the direction of the sliding track is arranged along the conveying direction of the conveyor belt.
[0010] Further, a rolling body is arranged at the upper end of the adjusting block, and the rolling body is rotatably connected with the adjusting block.
[0011] Further, one end of the telescopic device is rotatably connected with a connecting rod, and the other end is rotatably connected with a mounting seat.
[0012] Further, the horizontal connecting rod is fixed to the conveyor belt device through a first connecting rod and a second connecting rod, and the first connecting rod and the second connecting rod are equal in length and parallel to each other; So that the horizontal connecting rod can keep horizontal during the movement process.
[0013] The interval feeding mechanism for the solid wood processing automatic production line of the present invention has the following beneficial effects: Through the sliding connection design of the adjusting block and the horizontal connecting rod, and the arrangement of the sliding track along the conveying direction, the distance between the adjusting blocks can be quickly adjusted according to the width of the materials. With the rotating guiding function of the rolling body, stepless adaptation to different sizes of wood materials is realized, and the production line changeover adjustment time is shortened by more than 80%, significantly improving the flexibility level of the equipment.
[0014] The material distributing assembly adopts the rolling body lifting and separating technology. During the rising process of the horizontal connecting rod, rolling friction is formed between the rolling body and the materials, which reduces by more than 60% compared with the sliding friction of the traditional dial claws, effectively avoiding scratching the surface of the wood materials.
[0015] The material blocking component and the material separating component form a rigid linkage lever structure through a rotating shaft, and the precise synchronization of the blocking and material separating actions can be achieved by a single cylinder drive. Description of the Drawings

Detailed Embodiments
[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.
[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.
[0020] Such as Figures 1-4As shown in the figure, an intermittent feeding mechanism for an automated production line for solid wood processing includes a feeding motor assembly 1, a power transmission shaft 2, a conveying frame assembly 3, a sorting assembly 4, and a conveyor belt assembly 5. The feeding motor assembly 1 is in transmission connection with the power transmission shaft 2, and the power transmission shaft 2 is driven to rotate by the feeding motor assembly 1. The power transmission shaft 2 is connected to the conveyor belt assembly 5 through a shrink disc, and the conveying movement of the conveyor belt assembly 5 is realized by the rotation of the power transmission shaft 2. The feeding motor assembly 1, the power transmission shaft 2, and the conveyor belt assembly 5 are all arranged on the conveying frame assembly 3. The sorting assembly 4 is arranged at the middle position of the conveyor belt assembly 5, and the specific position is adjusted according to actual needs.
[0021] The sorting assembly 4 includes a cylinder push plate 401, a rotating shaft 403, a hook 404, and a horizontal connecting rod 406. The cylinder push plate 401, the rotating shaft 403, and the hook 404 cannot rotate relative to each other. One end of the cylinder push plate 401 is fixedly connected to the rotating shaft 403 and the other end is fixedly connected to the cylinder 417. The hook 404 is fixedly connected to the rotating shaft 403 and is arranged on the side of the conveyor belt assembly 5. The horizontal connecting rod 406 is fixed to the conveyor belt assembly 5 through a connecting rod 405 and a connecting rod 413. The lengths of the connecting rod 405 and the connecting rod 413 are equal and parallel to each other. The connecting rod 405, the connecting rod 413, the horizontal connecting rod 406, and the conveyor belt assembly 5 are all rotatably connected. The horizontal connecting rod 406 is kept horizontal during the movement through the parallel connecting rod 405 and the connecting rod 413. The horizontal connecting rod 406 is connected to the hook 404 through a push rod 415. The push rod 415 is rotatably connected to the horizontal connecting rod 406 and the hook 404. The connecting rod 405, the connecting rod 413, and the horizontal connecting rod 406 are connected through a pin 412 and a gasket 411. The connecting rod 405, the connecting rod 413, and the conveyor belt assembly 5 are connected through a pin 414. A Y joint 416 is arranged on the telescopic rod of the cylinder 417, and the cylinder push plate 401 is connected through the Y joint 416. The tail of the cylinder body of the cylinder 417 is rotatably connected to the cylinder mounting seat 418, and the cylinder mounting seat 418 is fixed on the cylinder mounting plate 419.
[0022] The cylinder 417 is pushed to drive the cylinder push plate 401 to drive the rotating shaft 403 to rotate, so that the hook 404 rotates to realize the switching between the material blocking state and the non-material blocking state. When the hook 404 rotates, the horizontal connecting rod 406 is driven to move up and down through the push rod 415. Specifically, one end of the hook 404 is provided with a blocking hook extending upward, and the other end is rotatably connected to the push rod 415. The rotating shaft 403 is connected between the blocking hook and the push rod 415, so that the hook 404 forms a lever structure with the rotating shaft 403 as the fulcrum. At this time, when the cylinder 417 extends, the blocking hook is lowered and the horizontal connecting rod 406 is raised, and the sorting assembly 4 is in the non-material blocking state. When the cylinder 417 retracts, the blocking hook is raised and the horizontal connecting rod 406 is lowered, and the sorting assembly 4 is in the material blocking state.
[0023] An adjustment block 410 is further provided on the horizontal connecting rod 406. When the horizontal connecting rod 406 rises, the adjustment block 410 jacks up the tail of the first wooden board blocked by the hook 404, so as to separate the first wooden board from the subsequent wooden boards. To facilitate matching wooden boards of different widths, the adjustment block 410 and the horizontal connecting rod 406 are adjustably connected. Specifically, a strip-shaped hole is provided on the horizontal connecting rod 406, and the adjustment block 410 is slidably connected to the strip-shaped hole through a bolt 407. A rolling body 409 is further provided at the upper end of the adjustment block 410, and the rolling body 409 is rotatably connected to the adjustment block 410 through a pin shaft 408. After the tail of the first wooden board blocked by the hook 404 is jacked up, the hook 404 enters a non-material-blocking state. At this time, the rolling body 409 can assist the conveyor belt assembly 5 to convey the wooden board, preventing the wooden board from getting stuck on the adjustment block 410.
[0024] The specific working principle is as follows. When the lumber moves to the single-piece separating assembly 4, the hook 404 of the single-piece separating assembly 4 blocks the lumber. Subsequently, the air cylinder 417 extends, and the air cylinder push plate 401 drives the rotating shaft 403 and the hook 404 to rotate counterclockwise. The hook 404 rotates below the conveyor belt, and the horizontal connecting rod 406 lifts upward, so that the adjustment block 410 and the rolling body 409 are higher than the conveyor belt. At this time, the first piece of lumber can move forward smoothly, while the second piece of lumber is blocked by the adjustment block 410 and the rolling body 409. When the air cylinder 417 retracts, the hook 404 rises, and the adjustment block 410 and the rolling body 409 descend. At this time, the second piece of lumber continues to move forward until it is blocked by the hook 404. By repeating the extension / retraction of the air cylinder, the interval feeding of the lumber can be realized.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
