Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to an automated feeding structure for processing short pieces of wood. Background Technology

[0002] Short timber usually refers to timber with a relatively short length. Among them, cylindrical timber needs to be fed through a feeding structure during the processing. Automated feeding of short timber is an important link in improving the efficiency and quality of timber processing. It can feed the timber into the processing device one piece at a time through piece-by-piece conveying.

[0003] Automated feeding is achieved by a control system that coordinates the operation of various components. This control system typically employs a programmable logic controller (PLC) or an industrial computer, and is programmed to precisely control parameters such as feeding speed, positioning accuracy, and feeding rhythm. Simultaneously, the control system can communicate with the wood processing equipment, automatically adjusting the feeding speed and quantity according to the processing progress, thus achieving automated integration of the entire processing process.

[0004] While existing feeding structures offer numerous advantages, they also suffer from several drawbacks. Firstly, their poor adaptability to different wood sizes hinders the individual feeding of timber of varying diameters, impacting the continuity of the feeding process and consequently affecting subsequent wood processing equipment and overall processing efficiency. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides an automated feeding structure for processing short timber.

[0006] The technical solution adopted by this utility model to solve its technical problem is an automated feeding structure for short timber processing, including a shell, a feeding hopper, and a rotary joint. A rotating shaft is rotatably installed on both sides of the inner wall of the shell. A roller is screwed to one end of the outer wall of the rotating shaft. A connecting hole is opened inside the roller. A circular array of receiving grooves is opened on the outer wall of the roller. The rotary joint is inserted and installed through one end of the outer wall of the shell. A liquid inlet pipe is inserted and installed at the other end of the rotary joint. A sleeve is inserted and installed on one side of the upper outer wall of the liquid inlet pipe. A feeding hopper is inserted and installed on the upper outer wall of the shell. Movable holes are opened on both sides of the inner wall of the feeding hopper. A linkage plate is installed inside the movable hole. A connecting frame is screwed to one side of the outer wall of the linkage plate. A screw is threaded into the connecting frame. A fixing frame is screwed to one side of the outer wall of the feeding hopper. A drive gear is rotatably installed inside the fixing frame.

[0007] By adopting the above technical solution, the inlet pipe can be flanged to the delivery pipe of the external liquid pump, thereby controlling the liquid pump to quantitatively deliver hydraulic oil through the external controller. The hydraulic oil is delivered through the inlet pipe to the sleeve and connecting hole, and the position of the adjusting plate inside the receiving trough can be adjusted to ensure that the space inside the receiving trough after adjustment can only hold a single piece of wood, thus enabling the individual delivery of wood. The matching motor is connected to the rotating shaft at the end away from the rotary joint through a coupling, so that the motor drives the drum to rotate, causing the receiving trough containing wood to rotate to the lower end of the outer shell. At this time, the wood is released from the obstruction of the outer shell and can be unloaded through the unloading pipe, ensuring the controllable unloading trajectory, the smoothness and stability of the individual wood delivery, the continuity of wood feeding, and the ability of the device to adapt to wood of different diameters. This improves the adaptability and functionality of the device for wood of different diameters and ensures the smoothness of wood feeding.

[0008] Specifically, a discharge pipe is inserted and installed on one side of the lower outer wall of the outer shell, and the discharge pipe is connected to the inside of the outer shell. Support feet are screwed to both sides of the outer wall of the outer shell.

[0009] By adopting the above technical solution, the support legs can provide stable support for the entire feeding structure, ensuring the stability of the equipment during operation, and the wood conveyed inside the shell can be unloaded through the unloading pipe.

[0010] Specifically, a first piston rod is movably installed inside the connecting hole, and an adjusting plate is screwed to the outer wall of the upper end of the first piston rod. The adjusting plate is located inside the receiving trough and has an arc-shaped design.

[0011] By adopting the above technical solution, and by controlling the input of hydraulic oil, the first piston rod and the second piston rod can be controlled to move within the connecting hole and the sleeve, respectively. The movement of the first piston rod allows the adjusting plate to move within the receiving trough, thereby adjusting the effective volume of the receiving trough. This ensures that the space inside the receiving trough is compatible with the size of the timber, accommodating short timber of different diameters and improving the versatility of the equipment. The arc-shaped design better fits the shape of the short timber, preventing the timber from shaking or slipping within the receiving trough and ensuring the stability of the feeding process.

[0012] Specifically, the upper outer wall of the linkage plate adopts an inclined design, a groove is provided on one side of the lower end of the inner wall of the movable hole, and a slider is installed on the lower outer wall of the linkage plate, and the slider is slidably installed inside the groove.

[0013] By adopting the above technical solution, wood can enter the interior of the outer shell through the feeding hopper, and the inner wall size of the feeding hopper can be adjusted by the linkage plate to ensure that the wood can be stacked one by one between the two linkage plates. The inclined shape helps the wood inside the feeding hopper to enter between the linkage plates. The slider and the groove restrict the movement trajectory of the linkage plate to ensure the smooth movement of the linkage plate.

[0014] Specifically, the thread openings on both sides of the screw are in opposite directions, and a driven gear is interference-fitted onto the outer wall of one side of the screw. The diameter of the driven gear is smaller than that of the driving gear, and the driven gear meshes with the driving gear.

[0015] By adopting the above technical solution, when the rack plate moves upward, the threaded connection between the connector and the screw can drive the adjusting plate to move horizontally. The two adjusting plates move in opposite directions, which can adjust the distance between the adjusting plates to ensure that the distance between the adjusting plates is adapted to the size of the wood. In practical applications, by controlling the gear ratio between the driven gear and the driving gear, the operator can ensure that the adjusted size between the adjusting plates is adapted to the adjusted size inside the receiving trough, ensuring that both are adapted to the size of the wood, thus providing a guarantee for the subsequent wood to enter the receiving trough one by one through the feeding hopper.

[0016] Specifically, a second piston rod is movably installed inside the sleeve, and a rack plate is screwed to the outer wall of the upper end of the second piston rod. The rack plate meshes with the drive gear.

[0017] By adopting the above technical solution, when the second piston rod moves upward synchronously with the hydraulic oil input, it can drive the drive gear to rotate through the rack plate. Since the driven gear meshes with the drive gear, it can drive the screw to rotate. Conversely, when the hydraulic oil is discharged, the second piston rod will move downward with the discharge amount, thereby driving the screw to reverse. The positions of the linkage plate and the adjustment plate can be adjusted accordingly.

[0018] Specifically, the upper end of the inner wall of the feed hopper is open, and the feed hopper is connected to the inside of the outer shell.

[0019] By adopting the above technical solution, the open design increases the feed port area, making it easier for operators to put short pieces of wood into the feed hopper. Furthermore, the wood inside the feed hopper can enter the outer shell after its movement is restricted by the linkage plate.

[0020] The beneficial effects of this utility model are:

[0021] (1) The automated feeding structure for short timber processing described in this utility model ensures the control of the unloading trajectory, the smoothness and stability of the timber being fed out piece by piece, and the continuity of timber feeding.

[0022] (2) The automated feeding structure for short timber processing described in this utility model provides a guarantee that the timber enters the receiving trough one by one through the feeding hopper, and ensures that the device can adapt to timber of different diameters, thereby improving the adaptability and functionality of the device to timber of different diameters and ensuring the smooth feeding of timber.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the automated feeding structure for short timber processing of this utility model includes a shell 1, a feeding hopper 2, and a rotary joint 3. A rotating shaft 13 is rotatably mounted on both sides of the inner wall of the shell 1. A roller 14 is screwed to one end of the outer wall of the rotating shaft 13. A connecting hole 16 is opened inside the roller 14. A circular array of receiving grooves 15 is opened on the outer wall of the roller 14. The rotary joint 3 is inserted and installed through one end of the outer wall of the rotating shaft 13. An inlet pipe 31 is inserted and installed at the other end of the rotary joint 3. A sleeve 32 is inserted and installed on one side of the upper outer wall of the inlet pipe 31. The feeding hopper 2 is inserted and installed on the upper outer wall of the shell 1. Movable holes 21 are opened on both sides of the inner wall of the feeding hopper 2. A linkage plate 23 is installed inside the movable hole 21. A connecting frame 24 is screwed to one side of the outer wall of the linkage plate 23. A screw rod 25 is threaded inside the connecting frame 24. A fixing frame 27 is screwed to one side of the outer wall of the feeding hopper 2. A drive gear 28 is rotatably mounted inside the fixing frame 27.

[0033] In use, the inlet pipe 31 can be flanged to the delivery pipe of the external hydraulic pump, thereby controlling the hydraulic pump to deliver hydraulic oil in a metered manner through the external controller. The hydraulic oil is delivered through the inlet pipe 31 to the sleeve 32 and the connecting hole 16. The position of the adjusting plate 18 inside the receiving trough 15 can be adjusted to ensure that the space inside the receiving trough 15 after adjustment can only hold a single piece of wood, thus enabling the individual delivery of wood. The matching motor is connected to the rotating shaft 13 at the end away from the rotary joint 3 through a coupling, thereby driving the roller 14 to rotate. The receiving trough 15 containing wood will rotate to the lower end inside the outer shell 1, and the wood will then be released from the obstruction of the outer shell 1 and can be unloaded through the unloading pipe 12. This ensures that the unloading trajectory is controlled, and that the individual delivery of wood is smooth and stable, ensuring the continuity of wood delivery. It also ensures that the device can adapt to wood of different diameters, improving the adaptability and functionality of the device for wood of different diameters, and ensuring the smoothness of wood delivery.

[0034] To maintain the usage location, for example, such as Figure 1 As shown, a discharge pipe 12 is inserted and installed on one side of the lower outer wall of the outer casing 1. The discharge pipe 12 is connected to the inside of the outer casing 1. Support legs 11 are screwed to both sides of the outer wall of the outer casing 1.

[0035] During use, the support legs 11 provide stable support for the entire feeding structure, ensuring the stability of the equipment during operation. The wood conveyed inside the outer casing 1 can be unloaded through the unloading pipe 12.

[0036] To adjust the containment space, for example, such as Figure 4 As shown, a first piston rod 17 is movably installed inside the connecting hole 16. An adjusting plate 18 is screwed to the outer wall of the upper end of the first piston rod 17. The adjusting plate 18 is located inside the receiving trough 15 and adopts an arc-shaped design.

[0037] During use, by controlling the input of hydraulic oil, the first piston rod 17 and the second piston rod 33 can be controlled to move within the connecting hole 16 and the sleeve 32, respectively. The movement of the first piston rod 17 allows the adjusting plate 18 to move within the receiving trough 15, thereby adjusting the effective volume of the receiving trough 15. This ensures that the space inside the receiving trough 15 is compatible with the size of the wood, accommodating short pieces of wood of different diameters and improving the versatility of the equipment. The arc-shaped design better fits the shape of the short pieces of wood, preventing the wood from shaking or slipping within the receiving trough 15 and ensuring the stability of the feeding process.

[0038] To control the feed space, for example, such as Figure 2 As shown, the upper outer wall of the linkage plate 23 is designed with an inclined shape, and a groove 22 is provided on one side of the lower end of the inner wall of the movable hole 21. A slider is installed on the lower outer wall of the linkage plate 23, and the slider is slidably installed inside the groove 22.

[0039] In use, the wood can enter the interior of the outer shell 1 through the feed hopper 2, and the inner wall size of the feed hopper 2 can be adjusted by the linkage plate 23 to ensure that the wood can be stacked one by one between the two linkage plates 23. The inclined shape helps the wood inside the feed hopper 2 to enter between the linkage plates 23. The slider and the groove 22 restrict the movement trajectory of the linkage plate 23 to ensure the smooth movement of the linkage plate 23.

[0040] For example, to enable coordinated movement, such as... Figure 3 As shown, the thread openings on both sides of the screw 25 are in opposite directions. A driven gear 26 is interference-fitted onto the outer wall of one side of the screw 25. The diameter of the driven gear 26 is smaller than the diameter of the driving gear 28, and the driven gear 26 meshes with the driving gear 28.

[0041] In use, when the rack plate 34 moves upward, the screw 25 is connected to the connecting piece, which drives the adjusting plate 18 to move horizontally. The two adjusting plates 18 move in opposite directions, which can adjust the distance between the adjusting plates 18 to ensure that the distance between the adjusting plates 18 is adapted to the size of the wood. In practical applications, the operator can control the gear ratio between the driven gear 26 and the driving gear 28 to ensure that the adjusted size between the adjusting plates 18 is adapted to the size inside the receiving trough 15 after being adjusted by the adjusting plates 18. This ensures that both are adapted to the size of the wood, providing a guarantee for the subsequent wood to enter the receiving trough 15 one by one through the feeding hopper 2.

[0042] For example, to enable coordinated movement, such as... Figure 6 As shown, a second piston rod 33 is movably installed inside the sleeve 32. A rack plate 34 is screwed to the outer wall of the upper end of the second piston rod 33, and the rack plate 34 meshes with the drive gear 28.

[0043] When in use, the second piston rod 33 moves upward synchronously with the hydraulic oil input, which drives the drive gear 28 to rotate through the rack plate 34. Since the driven gear 26 meshes with the drive gear 28, it can drive the screw 25 to rotate. Conversely, when the hydraulic oil is discharged, the second piston rod 33 will move downward with the discharge amount, thereby driving the screw 25 to reverse. The positions of the linkage plate 23 and the adjustment plate 18 can be adjusted accordingly.

[0044] For example, in order to feed material, such as Figure 2 As shown, the upper part of the inner wall of the feed hopper 2 is open, and the feed hopper 2 is connected to the inside of the outer shell 1.

[0045] When in use, the open design increases the feed port area, making it convenient for operators to put short pieces of wood into the feed hopper 2. The wood inside the feed hopper 2 can enter the outer shell 1 after its movement trajectory is restricted by the linkage plate 23.

[0046] When in use, this utility model uses an external controller to control a hydraulic pump to deliver hydraulic oil in a quantitative manner according to the diameter of the short timber. The hydraulic oil is delivered to the inside of the connecting hole 16 through the inlet pipe 31, which pushes the first piston rod 17 to move in the connecting hole 16. The first piston rod 17 drives the adjusting plate 18 to move in the receiving trough 15, thereby adjusting the effective volume of the receiving trough 15 so that the space of the receiving trough 15 is adapted to the size of the timber, ensuring that it can only hold a single type of timber.

[0047] Hydraulic oil is simultaneously delivered into the sleeve 32, pushing the second piston rod 33 upward. The second piston rod 33 drives the rack plate 34 upward, and the rack plate 34 drives the drive gear 28 to rotate. Since the driven gear 26 meshes with the drive gear 28, the drive gear 28 drives the driven gear 26 and the screw 25 to rotate. The screw 25 has opposite thread opening directions on both sides, driving the connecting frame 24 and the linkage plate 23 to move in the movable hole 21, adjusting the inner wall size of the feed hopper 2 so that the spacing between the linkage plates 23 matches the size of the wood.

[0048] The operator puts short pieces of timber into the feed hopper 2 through the open end. The timber enters between the two linkage plates 23 along the inclined upper outer wall of the linkage plate 23, and is stacked one by one. After the movement trajectory is restricted by the linkage plate 23, the timber enters the receiving trough 15 inside the outer shell 1.

[0049] Start the matching motor to drive the rotating shaft 13 and the drum 14 to rotate. The receiving trough 15 containing the wood rotates with the drum 14 to the lower end of the inner shell 1. When the receiving trough 15 rotates to the lower end of the inner shell 1, the wood is removed from the obstruction of the outer shell 1 and discharged through the unloading pipe 12, completing the feeding process.

[0050] It should be noted that this utility model is an automated feeding structure for processing short timber.
