Description

Technical Field

[0001] This utility model relates to the field of conveying technology, and in particular to a material anti-deviation limiter for a sawing machine. Background Technology

[0002] The materials used in a sawing machine mainly refer to the raw materials to be cut and the associated consumables involved in the sawing process. Raw materials include metals (such as steel and aluminum), wood, plastics, and composite materials, and are adapted to different workpieces of varying hardness and shape depending on the type of saw (such as metal sawing, woodworking sawing, and CNC sawing). Consumables include saw blades (such as high-speed steel and carbide saw blades), coolant, and lubricant, used to ensure cutting accuracy, efficiency, and equipment lifespan. The selection of materials must be based on the physical properties of the material being cut (such as hardness and toughness) and processing requirements to ensure consistent cutting quality.

[0003] In existing sawing technology, when materials are fed through a conveying device, limit switches are often used to prevent deviation. However, the position of traditional limit switches is often fixed, making it difficult to quickly adapt to the conveying needs of materials of different widths. When dealing with materials of various specifications, it is necessary to manually disassemble and adjust the limit components repeatedly, which is not only cumbersome and inefficient, but also prone to inaccurate positioning, affecting the stability of material conveying and sawing accuracy.

[0004] To address the above problems, a material anti-deviation limiter for sawing machines is proposed. Utility Model Content

It aims to improve the problem that the position of the existing anti-deviation limiter is often fixed, making it difficult to quickly adapt to the conveying needs of materials of different widths. When dealing with materials of various specifications, it is necessary to manually disassemble and adjust the limiting components repeatedly, which is not only cumbersome and inefficient, but also easily leads to inaccurate limiting, affecting the stability of material conveying and sawing accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sawing machine material anti-deviation limiter, comprising a housing and a second limit frame, a movable frame slidably connected to the inner wall of the housing, a first limit frame fixedly connected to the outer side of the movable frame, an adjustment component provided between the first limit frame and the second limit frame, a rack fixedly connected to the inner wall of the movable frame, a fixing component provided at the top of the housing, and an installation component provided at the bottom of the housing;

[0007] The fixing assembly includes a rotating rod and a thin shell. The outer side of the thin shell is fixedly connected to the top of the outer shell. The outer side of the rotating rod is rotatably connected to the inside of the outer shell. A gear is fixedly connected to the outer side of the rotating rod. A rotating disk is fixedly connected to the top of the rotating rod. Multiple limiting grooves are opened inside the rotating disk. A limiting plate is fixedly connected to the top of the thin shell. A pull rod is slidably connected inside the thin shell. A baffle is fixedly connected to the outer side of the pull rod. A spring is sleeved on the outer side of the pull rod. A blocking block is provided on the top of the baffle. A handle is fixedly connected to the top of the rotating disk.

[0009] The adjustment assembly includes a U-shaped plate, the outer side of which is fixedly connected to the right end of the limiting frame one. A connecting shaft is rotatably connected inside the U-shaped plate, and a worm gear is fixedly connected to the outer side of the connecting shaft. A fixed shell is fixedly connected to the top of the U-shaped plate, and a worm is rotatably connected inside the fixed shell. The worm and the worm gear are meshed together. A limiting frame two is fixedly connected to the outer side of the connecting shaft.

[0010] As a further description of the above technical solution:

[0011] The mounting assembly includes a mounting base plate, the top of which is fixedly connected to the bottom of the housing. A lead screw is threaded into the mounting base plate, a fixing plate is fixedly connected to the top of the lead screw, and a handle is fixedly connected to the bottom of the fixing plate.

[0012] As a further description of the above technical solution:

[0013] One end of the spring is fixedly connected to the outside of the baffle, and the other end of the spring is fixedly connected to the inner wall of the thin shell.

[0014] As a further description of the above technical solution:

[0015] The outer side of the baffle is slidably connected to the inner wall of the thin shell, and the outer side of the pull rod is inserted into the inner wall of one of the limiting grooves.

[0016] As a further description of the above technical solution:

[0017] The lower outer part of the blocking block is slidably connected to the inside of the thin shell, and the upper outer part of the blocking block is slidably connected to the outside of the limiting plate.

[0021] Both the first limiting frame and the second limiting frame are rotatably connected by multiple rollers.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by pulling the pull rod outward, the baffle compresses the spring, causing the pull rod to disengage from the limiting groove. The blocking block slides down due to gravity, preventing the pull rod from resetting. By rotating the handle, the moving frame is driven to move the limiting frame one through the transmission of the rotating rod, gear, and rack, changing its position relative to the limiting frame two. After adjustment, the blocking block is pulled up, and the spring rebounds, causing the pull rod to insert into the limiting groove and locking the position of the limiting frame one. This realizes the adjustment of the positions of the limiting frame one and the limiting frame two, which can quickly adapt to the conveying needs of materials of different widths, limit the material during the conveying process, and prevent it from deviating during the conveying process.

[0024] 2. In this utility model, by rotating the worm inside the fixed shell, because it meshes with the worm wheel, the rotation of the worm causes the worm wheel and the connecting shaft to rotate within the U-shaped plate and the fixed shell, thereby causing the second limiting frame on the outside of the connecting shaft to rotate, realizing multi-angle flexible adjustment of the angle of the second limiting frame, which can adapt to the material requirements of different conveying angles.

[0041] Working principle: During the material conveying process of the sawing machine, firstly, the handle 25 at the bottom of the fixed plate 24 in the mounting assembly is rotated, which drives the lead screw 23 to rotate inside the mounting base plate 22. Since the lead screw 23 is threadedly connected to the mounting base plate 22, as it rotates, the fixed plate 24 of the lead screw 23 abuts against the mounting surface, and the outer shell 1 is securely installed on the outside of the conveying device.

[0042] When the spacing between the limit frames needs to be adjusted to match the material conveying width, pull the lever 14 outward, causing the baffle 26 to slide inside the thin shell 11 and compress the spring 13, so that the lever 14 disengages from the limiting groove 9 of the rotating disk 8. At this time, the blocking block 15 slides into the thin shell 11 under the action of gravity, preventing the baffle 26 from being pushed by the spring 13 to re-insert the lever 14 into the inner wall of the limiting groove 9. At this time, turn the handle 10 to drive the rotating disk 8 and the rotating rod 7 to rotate. The gear 6 on the rotating rod 7 rotates accordingly. Since the gear 6 meshes with the rack 5 on the inner wall of the moving frame 2, the rotation of the gear 6 drives the moving frame 2 to slide on the inner wall of the outer shell 1, thereby driving the outer limit frame 3 to move, changing the position of the limit frame 3 and the limit frame 16. After the adjustment is in place, pull the blocking block 15 upward, and the spring 13 rebounds to push the baffle 26, so that the lever 14 inserts into the corresponding limiting groove 9, fixing the rotating disk 8 and the rotating rod 7, and locking the position of the limit frame 3.

[0043] To adjust the angle of the second limiting bracket 16 relative to the first limiting bracket 3, rotate the worm 20 inside the fixed shell 21. Because it meshes with the worm wheel 19, the rotation of the worm 20 drives the worm wheel 19 and the connecting shaft 18 to rotate within the U-shaped plate 17 and the fixed shell 21, thereby causing the second limiting bracket 16 outside the connecting shaft 18 to rotate, thus achieving angle adjustment.

[0044] During material conveying, the material passes between limit frame 1 (3) and limit frame 2 (16). The multiple rollers 4 that are rotatably connected between the two greatly reduce the friction between the material and the limit frame, ensuring smooth passage of the material. At the same time, limit frame 1 (3) and limit frame 2 (16) limit the material to prevent it from deviating during the conveying process, thus ensuring the sawing machine can accurately cut the material.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
