A feeding and receiving groove of a long material flaking grabber

Abstract

This utility model discloses a feeding trough for a long timber slicing grabber, including a frame; the frame is provided with a trough with a semi-circular cross-section, and a front baffle and a rear baffle are respectively provided at both ends of the trough. The advantages of this utility model are: under the continuous guiding action of the arc-shaped surface, round timbers of the same length naturally roll down the arc surface to the center area of ​​the trough bottom under the combined action of their own gravity and rolling inertia. During the process, the timbers gradually tend to be vertical due to the downward shift of the center of gravity and lateral constraint, effectively eliminating the initial posture deviation, achieving high consistency of the timber axis and orderly arrangement with roughly flush ends, playing a role in naturally aligning the timbers, making it easier for the grabber to grab and feed the long timber slicing machine.

Description

Technical Field

[0001] This utility model relates to the technical field of wood processing equipment, and in particular to a feeding trough for a long wood chipping and grabbing machine. Background Technology

[0002] In the timber processing industry, especially in the preceding process of long timber chippers, the debarked standard timber (round logs) is usually transported to a storage tank via a conveyor belt for temporary storage, and then picked up one by one by a log grabber from the storage tank and sent to the subsequent chipping processing equipment. In existing technologies, peeled timber is often directly thrown into the storage trough via a conveyor belt or falls freely. Due to the significant kinetic energy of the timber during high-speed transport, the impact force upon entering the trough is large, and the timber's posture is random, often resulting in disordered stacking phenomena such as tilting, overlapping, and even corner jamming. This leads to a chaotic arrangement of timber within the frame, with uneven ends and inconsistent axial direction. This not only reduces the space utilization rate of the storage trough but also severely impacts the gripping operation of the timber grabber: on the one hand, because the timber is scattered and has varying postures, the grippers are difficult to accurately center and close, easily resulting in empty gripping, off-center gripping, or only gripping a few pieces of timber; on the other hand, the chaotic arrangement prevents multiple pieces of timber from forming a stable bundle structure, making it easy for the grippers to slip or scatter during gripping. This forces a reduction in the number of pieces gripped at one time to ensure stability, leading to increased gripping frequency, longer cycle times, and overall low efficiency. This has resulted in persistent problems such as low gripping efficiency and insufficient equipment utilization, becoming a key technical bottleneck restricting the capacity improvement of the production line. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a feeding trough for a long timber slicing and grabbing machine.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A feeding trough for a long timber slicing and gnawing machine includes a frame; the frame is provided with a trough with a semi-circular cross-section, and a front baffle and a rear baffle are respectively provided at both ends of the trough.

[0006] As a preferred embodiment of the present invention, the frame includes a bottom frame, top rods located above the bottom frame and fixedly connected to the two top edges of the tank, columns connecting the top rods and the bottom frame, and a grid frame that fits against the bottom surface of the tank, wherein the grid frame is fixedly connected to the top rods.

[0007] As a preferred embodiment of this invention, the upper edge of the front baffle is lower than the upper edge of the rear baffle.

[0008] As a preferred embodiment of this utility model, an openable and closable door is provided at the lower part of the front baffle.

[0009] As a preferred technical solution of this utility model, the door body is fixedly connected to the front baffle through a snap-fit ​​structure.

[0010] As a preferred embodiment of this utility model, the grid frame adopts a grid-like grid.

[0011] As a preferred embodiment of this utility model, the tank is made of steel plate.

[0012] The above technical solution has the following advantages:

[0013] The receiving trough provided by this utility model features a trough structure with semi-circular arc sides and baffles at both ends. After being peeled and fed at high speed by an accelerating belt, the timber first collides with the semi-circular sidewalls, consuming some kinetic energy. Under the continuous guidance of the arc surface, the timber naturally rolls down the arc surface to the center of the trough bottom under its own weight and rolling inertia. During this process, the timber gradually tends to be vertical due to the downward shift of its center of gravity and lateral constraint, effectively eliminating initial posture deviations and achieving high consistency in the axial direction of the timber and an orderly arrangement with roughly flush ends. This structure fully utilizes the laws of physical motion, requiring no additional power drive or complex control system, and can automatically align the timber before it enters the storage trough, significantly improving the density and neatness of the timber arrangement within the storage space. This design avoids problems such as stacking chaos and mutual jamming, providing a reliable guarantee for the subsequent accurate, stable, and efficient gripping of single logs by the log grabber. It significantly reduces the occurrence of empty gripping, off-center gripping, and jamming failures, improving the gripping cycle time and overall line operating efficiency. At the same time, the semi-circular arc surface not only realizes the gathering and alignment of logs, but its arc structure also serves as a motion guide surface for the gripper's claws. During the gripping process, it guides the claws to close precisely and symmetrically on both sides of the log bundle, effectively improving the stability and reliability of the gripping. It also allows multiple aligned logs to be gripped at once, significantly increasing the number of logs gripped at one time and further improving the working efficiency of the log grabber. The overall structure is compact, with low manufacturing cost, stable operation, and simple maintenance. It has good practicality, reliability, and economy, and is suitable for large-scale continuous wood processing production lines. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1

[0025] As attached Figure 1-4 As shown, a feeding trough for a long timber shaving and grapple includes a frame 1; a trough 2 with a semi-circular cross-section is provided on the frame 1, and a front baffle 3 and a rear baffle 4 are respectively provided at both ends of the trough 2.

[0026] As a preferred technical solution in this embodiment, the frame 1 includes a bottom frame 11, top rods 12 located above the bottom frame 11 and fixed to the two top edges of the trough 2 respectively, columns 13 connecting the top rods 12 and the bottom frame 11, and a grid frame 14 that fits against the bottom surface of the trough 2. The grid frame 14 is fixed to the top rods 12. The frame 1 has a stable structure and is supported by the columns 13. The top rods 12 and the bottom frame 11 form an upper and lower connection, which enhances the overall rigidity. The grid frame 14 not only supports the trough 2, but its open structure also allows debris, dust or other debris to fall, avoiding accumulation that affects the slippage of the wood. The frame 1 can be welded from square tubes or angle steel, which has the advantages of low cost, high strength, and easy processing and installation.

[0027] As a preferred technical solution in this embodiment, the upper edge of the front baffle 3 is lower than the upper edge of the rear baffle 4, forming an inclined arrangement with the rear higher than the front. This facilitates the natural forward sliding of the wood under the action of gravity and its concentration on the side of the rear baffle 4. At the same time, it provides a good spatial layout for the subsequent log grabber to grab from the front, improving the smoothness of the grabbing.

[0028] As a preferred technical solution in this embodiment, the lower part of the front baffle 3 is provided with an openable and closable door 5. During normal operation, the door 5 is closed to prevent the wood from sliding out prematurely, ensuring that the wood is fully aligned in the trough 2. When maintenance and cleaning are required, the door 5 can be opened to quickly discharge accumulated materials and debris, improving equipment maintenance efficiency. The door 5 structure can be replaced by a detachable plate or an automatic opening and closing valve to adapt to different working conditions.

[0029] As a preferred technical solution in this embodiment, the door body 5 is fixedly connected to the front baffle 3 through a snap-fit ​​structure, which enables quick disassembly and assembly. Opening and resetting can be completed without tools, making the operation convenient. Alternatively, hinge connection with latch, bolt fixing or magnetic structure can be used to improve connection flexibility.

[0030] As a preferred technical solution in this embodiment, the grid frame 14 adopts a grid-like grid, which has a symmetrical structure and uniform load-bearing capacity, which is conducive to maintaining the structural strength of the tank 2 without deformation.

[0031] As a preferred technical solution in this embodiment, the tank 2 is made of steel plate with a thickness of 12mm. It has good strength, rigidity and wear resistance, and can withstand the impact and friction of the standard material for a long time without being easily deformed or damaged, thus extending its service life.

[0032] At work, such as Figure 5 As shown, the long logs (round logs) peeled by the peeling machine 100 are quickly output by the belt conveyor 200 and enter the trough 2 from the front baffle 3 of the receiving trough 300. The receiving trough 300 achieves natural alignment of the logs before they enter the storage frame through the semi-circular trough 2. The logs roll down the arc surface to the center of the trough bottom, automatically gather and align with the axis (the axis of the round logs is basically parallel to the axis of the trough 2), effectively improving the neatness of the arrangement. At the same time, the arc-shaped trough 2 can also serve as a guide surface for the gripper's claws, guiding the claws to close symmetrically, improving the gripping stability, and significantly increasing the number of logs grabbed at one time. The overall structure does not require power drive and can efficiently complete the alignment of logs by relying on physical principles, greatly reducing the phenomena of empty grabbing, off-center grabbing and jamming, improving the operating efficiency of the log grabper and the automation level of the entire line. It has the advantages of simple structure, reliable operation, convenient maintenance and strong practicality.
