Description

Technical Field

[0001] This utility model relates to the field of lathe loading technology, and in particular to an anti-jamming mechanism for an automatic loading lathe. Background Technology

[0002] An automatic feeding lathe is a type of equipment used for wood processing. It can automatically feed wood into the lathe for processing, improving production efficiency. This lathe typically features high-precision cutting and automated operation functions, making it suitable for mass production. Because wood may jam during processing due to irregular shape or changes in humidity, leading to equipment downtime, damage, or reduced processing accuracy, anti-jamming design is crucial.

[0003] The loading mechanism of a traditional woodworking lathe works by placing the wood in an inclined limiting frame, and then using gravity to slowly move the wood from top to bottom onto a push rod. The push rod then moves the wood to the processing area and works in conjunction with the cutting mechanism to process the wood.

[0004] Because traditional feeding mechanisms rely solely on gravity to lower the timber, uneven surface treatment at both ends of the timber can easily increase the resistance between the timber ends and the limiting frame, causing the timber to get stuck in the limiting frame. This not only affects production efficiency but may also increase the risk of equipment failure and reduce processing accuracy. Utility Model Content

[0005] Therefore, it is necessary to provide an anti-jamming mechanism for an automatic feeding lathe to address the problem of timber easily getting stuck on the feeding mechanism.

[0006] An anti-jamming mechanism for an automatic feeding lathe includes: a guide rail and a milling and turning mechanism disposed above the guide rail;

[0007] The feeding mechanism includes a feeding frame that is inclined to the ground, a feeding port that is opened near the top of the feeding frame, an anti-jamming component that is installed inside the feeding frame, and a pushing component that is installed at the bottom of the feeding frame.

[0008] In one embodiment, the anti-jamming component includes an electric push rod fixedly connected to the top of the feeding rack, the driving end of the electric push rod being fixedly connected to a drive plate, and both ends of the drive plate being slidably connected to the inner wall of the feeding rack.

[0009] In one embodiment, multiple adjustment plates are provided on both sides of the inner side of the feeding rack, and the adjustment plates are arc-shaped.

[0010] In one embodiment, the uppermost adjustment plate is horizontally positioned and aligned with the feed inlet, while the other adjustment plates are vertically positioned.

[0011] In one embodiment, a plurality of rollers are rotatably connected to the surface of the adjusting plate, and an adjusting rod is fixedly connected to the back of the adjusting plate.

[0012] In one embodiment, multiple positioning rods are fixedly connected to the inner walls of both sides of the feeding rack, the adjusting rod is slidably connected to the inner wall of the positioning rod, and a spring is fixedly connected between the adjusting rod and the inner bottom wall of the positioning rod.

[0013] In one embodiment, the pushing assembly includes two hydraulic cylinders mounted below the feeding frame, and the drive ends of the two hydraulic cylinders are fixedly connected to connecting rods.

[0014] Beneficial effects

[0015] 1. By installing adjustable plates with automatically adjustable spacing on both sides of the loading rack, the spacing of the plates can be adjusted according to the unevenness of the wood's surfaces at both ends as it moves within the rack, thereby reducing the resistance between the wood and the limiting frame. This allows the wood to move smoothly during the loading process and reduces the probability of it getting stuck on the rack due to uneven surfaces at both ends. Simultaneously, the adjustable plates can also accommodate wood of different sizes to a small extent, improving the flexibility of the loading process.

[0016] 2. By installing rollers on the adjusting plate, the friction between the ends of the wood and the surface of the adjusting plate can be further reduced. This allows for smoother feeding of the wood while reducing the contact resistance between the wood surface and the adjusting plate, thereby further reducing the probability of jamming. It also slows down the wear and tear on the equipment, increasing its service life. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined Figures 1-5 This invention describes the anti-jamming mechanism of an automatic feeding lathe.

[0027] In one embodiment, an anti-jamming mechanism for an automatic feeding lathe includes: a guide rail 100 and a milling and turning mechanism 200 disposed above the guide rail 100.

[0028] The feeding mechanism 300 includes a feeding rack 310 that is inclined to the ground. The feeding rack 310 has a feeding port 311 near the top. The feeding rack 310 is equipped with an anti-jamming component 320 inside and a pushing component 330 at the bottom.

[0029] In this device, the milling and turning mechanism 200 is composed of the following main components:

[0030] The high-speed electric spindle is driven by a motor, with built-in encoder feedback and adjustable speed, used to drive the wood to rotate at high speed;

[0031] The hydraulic chuck, located on the horizontal displacement line of the spindle, is driven by a hydraulic rod and is compatible with wood of different diameters. It is rotatably connected to the hydraulic rod via an adapter and is used to clamp the wood in the processing area.

[0032] The milling cutter is mounted on the guide rail 100 via a mounting base and has an adjustable height. It is used for milling high-speed rotating wood.

[0033] The guide rail 100 circulates within the slider of the guide rail 100 via pre-tightened rollers. The ball screw driven by the stepper motor moves the entire milling and turning mechanism 200 along the X / Z axis, achieving precise positioning under the control of the CNC system. The milling and turning mechanism 200, guide rail 100, and loading mechanism 300 of this device are all controlled by the CNC console, and corresponding programming is required according to the wood processing before operation.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the anti-jamming component 320 includes an electric push rod 321 fixedly connected to the top of the loading rack 310. A drive plate 322 is fixedly connected to the drive end of the electric push rod 321, and both ends of the drive plate 322 are slidably connected to the inner wall of the loading rack 310. Multiple adjusting plates 323 are provided on both sides of the interior of the loading rack 310, and the adjusting plates 323 are arc-shaped. The uppermost adjusting plate 323 is horizontally positioned and aligned with the loading port 311, while the other adjusting plates 323 are vertically positioned. Multiple rotating rollers 3231 are rotatably connected to the surface of the adjusting plate 323, and an adjusting rod 324 is fixedly connected to the back of the adjusting plate 323. Multiple positioning rods 325 are fixedly connected to the inner walls of both sides of the loading rack 310. The adjusting rod 324 is slidably connected to the inner wall of the positioning rod 325, and a spring 326 is fixedly connected between the adjusting rod 324 and the inner bottom wall of the positioning rod 325.

[0035] In this embodiment, the electric push rod 321 moves a distance equal to the distance a piece of wood falls from the loading rack 310. That is, the electric push rod 321 drives the drive plate 322 to push the overlapping wood. When the bottom piece of wood falls onto the pushing assembly 330, the drive end of the electric push rod 321 resets. At this point, the worker needs to add new wood to the loading rack 310 through the loading port 311. When the wood enters the loading port 311, the adjusting plates 323 on both sides, in conjunction with the spring 326, automatically adjust the wood to the loading position. The wood is placed at the center of the frame 310 and needs to be compacted so that it fits against the inner wall of the frame 310. Since the frame 310 is tilted, and with the pressure applied by the adjusting plate 323, the wood will always remain inside the frame 310 and will not come into contact with the loading port 311, thus preventing jamming. As the wood moves downward, the roller 3231 is embedded in the surface of the adjusting plate 323, and the angle between the exposed surface and the adjusting plate 323 is large, so the edge of the wood will not get stuck with the roller 3231.

[0036] It should be noted that the anti-jamming component 320 of this device uses adjusting plates 323 on both inner walls of the loading rack 310, along with positioning rods 325 and adjusting rods 324, to adaptively adjust both ends of the wood. A rotating roller 3231 reduces friction between the wood and the loading rack 310, allowing the wood to move smoothly within the loading rack 310. Since the anti-jamming component 320 is located inside the loading rack 310 and adaptively adjusts both ends of the wood, it will not affect the normal operation of the milling mechanism 200 or the pushing component 330. Therefore, the anti-jamming component 320 will not affect the lathe's processing of wood.

[0037] like Figure 1 , Figure 2 and Figure 5 As shown, the feeding assembly 330 includes two hydraulic cylinders 332 installed below the feeding rack 310. The driving ends of the two hydraulic cylinders 332 are fixedly connected to connecting rods, and the surfaces of the connecting rods are fixedly connected to two limiting blocks 331. The cross-section of the limiting blocks 331 is "Z" shaped.

[0038] In this embodiment, the hydraulic cylinder 332 is driven by a hydraulic pump and controlled by a CNC console to cooperate with the electric push rod 321 and the milling and turning mechanism 200. The specific process is as follows: the electric push rod 321 moves a certain distance according to the programmed data and pushes the wood onto the two limit blocks 331. At this time, the electric push rod 321 resets, and the hydraulic cylinder 332, driven by the hydraulic pump, pushes the limit blocks 331 and the wood on the limit blocks 331 to the center of the machining axis. At this time, the hydraulic chuck cooperates with the machining axis to clamp the wood and start to rotate, and cooperates with the milling cutter to mill the wood.

[0039] Working principle: Wood is added to the loading rack 310 through the loading port 311. Then, the electric push rod 321 is activated. The electric push rod 321 pushes the wood downwards a certain distance through the drive plate 322 and then resets. This process is repeated until the loading rack 310 is full of wood. At this time, the electric push rod 321 pushes the wood at the top, causing the wood below to fall onto the pushing assembly 330. The pushing assembly 330 carries the wood to the processing area, where the milling and turning mechanism 200 processes the wood.

[0040] As the timber moves within the loading rack 310, the two ends of the timber press against the adjusting plate 323. The adjusting plate 323 slides along the inner wall of the loading rack 310, causing the adjusting rod 324 to move within the positioning rod 325 and compress the spring 326. The elastic force of the spring 326 keeps the adjusting plate 323 in contact with both ends of the timber. The timber continues to move downward on the surface of the rotating roller 3231 under the push of the electric push rod 321, preventing the two ends of the timber from getting stuck inside the loading rack 310.

[0041] It should be noted that the guide rail 100, milling mechanism 200, electric push rod 321, hydraulic cylinder 332 and spring 326 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the guide rail 100, milling mechanism 200, electric push rod 321 and hydraulic cylinder 332 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
