Description

Technical Field

[0001] This utility model relates to the field of tooth-forming machine technology, and in particular to a belt-driven continuous tooth-forming machine. Background Technology

[0002] In daily work, toothed joints are generally required when connecting belts. In order to ensure the quality of the toothed joint, it is crucial to make teeth at the ends of the belt. Generally, a toothing machine is used to make teeth at the ends of the belt.

[0003] Chinese utility model patent CN218428632U discloses a PVC belt toothing machine, including a frame, a clamping mechanism, a toothed cutter, and a pressing mechanism. The frame is movable, and the clamping mechanism, the toothed cutter, and the pressing mechanism are respectively mounted on the frame. The pressing mechanism is located above the toothed cutter and is used to press the PVC belt towards the toothed cutter. The pressing mechanism is slidably connected to the frame. The disadvantage of this PVC belt toothing machine is that manual tooth alignment is required before toothing. Manual alignment can lead to errors, resulting in inaccurate tooth alignment and mismatch between the tooth profiles at both ends of the belt, affecting the tooth joint at both ends. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a continuous belt toothing machine to solve the technical problem that the existing toothing machine requires manual positioning and alignment of teeth before toothing. Manual positioning and alignment will result in errors, leading to inaccurate tooth alignment, which in turn causes the tooth shape at both ends of the belt to be mismatched and affects the tooth connection at both ends of the belt.

[0005] To achieve the above technical objectives, the present invention provides a continuous belt toothing machine, including a frame, a pressing mechanism slidably mounted on the top of the frame, a toothed cutter mounted below the pressing mechanism, a clamping mechanism mounted in front of the toothed cutter, and a tooth-aligning assembly mounted in front of the toothed cutter. The tooth-aligning assembly includes a slide rail, a slider slidably mounted on the slide rail, a limit plate mounted on the slider, and at least two arc-shaped slots evenly spaced on the side wall of the slide rail. A roller matching the arc-shaped slot is provided inside the arc-shaped slot, and the roller is rotatably mounted on a mounting base. The mounting base is connected to the slider via an elastic element.

[0006] Furthermore, the slide rail is provided with a T-shaped limiting block, and the slider is provided with a T-shaped limiting groove that matches the T-shaped limiting block. The slider and the slide rail are slidably connected through the T-shaped limiting block and the T-shaped limiting groove.

[0007] Furthermore, a first limit head is installed at both ends of the T-shaped limit block.

[0008] Furthermore, the roller is provided with a T-shaped rotating groove, and the mounting base is provided with a T-shaped rotating block that matches the T-shaped rotating groove. The roller and the mounting base are rotatably connected through the T-shaped rotating groove and the T-shaped rotating block.

[0009] Furthermore, a guide rod is installed on the slider, and a guide hole is provided on the mounting base to cooperate with the guide rod. The mounting base is slidably mounted on the guide rod through the guide hole.

[0010] Furthermore, a second limit head is installed at the end of the guide rod away from the slider.

[0011] Furthermore, a handle is installed on the slider.

[0012] The beneficial effects of this utility model include: This utility model provides a continuous belt toothing machine. When toothing a belt, one end of the belt is placed on the toothed cutter, and the side wall of the belt abuts against the limiting plate. This allows for positioning and tooth alignment of one end of the belt before toothing. After toothing is completed at one end of the belt, the slider is slid, which drives the roller to roll into the adjacent arc-shaped groove. The position of the limiting plate is adjusted to ensure that the tooth shapes at both ends of the belt are compatible. After adjustment, the other end of the belt is placed on the toothed cutter, and the side wall of the belt abuts against the limiting plate. This allows for positioning and tooth alignment of the other end of the belt before toothing, avoiding the problem of inaccurate manual tooth alignment that could lead to mismatched tooth shapes at both ends of the belt and affect the tooth joint.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] This utility model embodiment provides a continuous belt toothing machine, such as Figure 1 As shown, the device includes a frame 1, a pressing mechanism 2 slidably mounted on the top of the frame 1, a toothed cutter 3 mounted below the pressing mechanism 2, and a clamping mechanism 4 mounted in front of the toothed cutter 3. When the belt is toothed, the belt is placed on the toothed cutter 3. After placement, the belt can be clamped by the clamping mechanism 4. When the belt is clamped, the pressing mechanism 2 can press the belt to tooth it. The pressing mechanism 2, the toothed cutter 3, and the clamping mechanism 4 are all existing technologies, and their specific structures will not be described in detail here.

[0019] In this embodiment, a tooth-matching assembly 5 is also installed in front of the toothed cutter 3. More specifically, as shown in the example... Figure 2 As shown, the tooth assembly 5 includes a slide rail 51, a slider 52 slidably mounted on the slide rail 51, a limit plate 53 mounted on the slider 52, and at least two arc-shaped slots 511 evenly spaced on the side wall of the slide rail 51. A roller 54 matching the arc-shaped slot 511 is provided inside the arc-shaped slot 511. The roller 54 is rotatably mounted on a mounting base 55, which is connected to the slider 52 via an elastic element 56. When toothing the belt, one end of the belt is placed on the toothed cutter 3, and the side wall of the belt abuts against the limit plate 53, thus allowing toothing to be performed on one end of the belt before it is toothed. For positioning and tooth alignment, after one end of the belt is toothed, slide the slider 52. The slider 52 can drive the roller 54 to roll, so that the roller 54 rolls into the adjacent arc-shaped groove 511. Adjust the position of the limiting plate 53 so that the tooth shape at both ends of the belt is matched. After adjustment, place the other end of the belt on the toothed cutter 3, and at the same time, abut the side wall of the belt with the limiting plate 53. This can position and align the other end of the belt before toothing, which can avoid the problem of inaccurate manual positioning and tooth alignment, which would cause the tooth shape at both ends of the belt to be mismatched and affect the tooth connection at both ends of the belt.

[0020] It should be noted that the distance between the midpoints of two adjacent arc-shaped grooves 511 is half the width of a single tooth on the toothed cutter 3, so as to make the tooth shape of the two ends of the belt match when teething the two ends of the belt.

[0021] It should be noted that there is a smooth transition between two adjacent arc-shaped slots 511 so that the roller 53 can smoothly roll from the inside of one arc-shaped slot 511 to the inside of the adjacent arc-shaped slot 511.

[0022] In this embodiment, the slide rail 51 is provided with a T-shaped limiting block 512, and the slider 52 is provided with a T-shaped limiting groove 521 that matches the T-shaped limiting block 512. The slider 52 and the slide rail 51 are slidably connected through the T-shaped limiting block 512 and the T-shaped limiting groove 521. At the same time, a first limiting head 513 is installed at both ends of the T-shaped limiting block 512 to prevent the T-shaped limiting block 512 from disengaging from the T-shaped limiting groove 521.

[0023] In this embodiment, as Figure 3 As shown, the roller 54 is provided with a T-shaped rotating groove 541, and the mounting base 55 is provided with a T-shaped rotating block 551 that matches the T-shaped rotating groove 541. The roller 54 and the mounting base 55 are rotatably connected through the T-shaped rotating groove 541 and the T-shaped rotating block 551.

[0024] In this embodiment, a guide rod 522 is installed on the slider 52, and a guide hole 552 that cooperates with the guide rod 522 is provided on the mounting base 55. The mounting base 55 is slidably mounted on the guide rod 522 through the guide hole 552. When the roller 54 rolls from one of the arc-shaped slots 511 to the interior of the adjacent arc-shaped slot 511, the elastic element 56 undergoes elastic deformation. At the same time, the mounting base 55 will move towards or away from the slider 52. The mounting base 55 can move stably by cooperating with the guide rod 522 and the guide hole 552. Meanwhile, a second limiting head 523 is installed at the end of the guide rod 522 away from the slider 52 to prevent the mounting base 55 from detaching from the guide rod 522.

[0025] In this embodiment, the elastic element 56 is a spring. When the elastic element 56 is a spring, the spring 56 is sleeved on the guide rod 522, and the two ends of the spring 56 are respectively connected to the mounting base 55 and the second limiting head 523. The elastic element 56 in this embodiment is not limited to the form of a spring. For example, in some other embodiments, the elastic element 56 is a metal sheet or other elastic object.

[0026] In this embodiment, a handle 524 is installed on the slider 52. When the operator slides the slider 52, they can hold the handle 524 to push and pull the slider 52, which makes it convenient for the operator to slide the slider 52.

[0027] Specific principle: When toothing the belt, one end of the belt is placed on the toothed cutter 3, and the side wall of the belt abuts against the limiting plate 53. This allows for positioning and tooth alignment of one end of the belt before toothing. After tooth alignment, the clamping assembly 4 clamps and fixes one end of the belt. Once clamped, the pressing mechanism 2 presses down on one end of the belt, causing the toothed cutter 3 to cut the belt end into a sawtooth shape. After toothing is complete, the sliding slider 52 drives the roller 54 to roll, causing the roller 54 to roll into the adjacent arc-shaped slot 511, thus aligning the limiting plate. The position of the positioning plate 53 is adjusted to make the tooth shape at both ends of the belt match. After adjustment, the other end of the belt is placed on the toothed cutter 3, and the side wall of the belt is abutted against the limiting plate 53. This allows the other end of the belt to be positioned and aligned before toothing. After alignment, the other end of the belt is clamped and fixed by the clamping assembly 4. After the other end of the belt is clamped and fixed, the pressing mechanism 2 presses the other end of the belt, causing the toothed cutter 3 to cut the other end of the belt into a sawtooth shape. This avoids the problem of inaccurate manual positioning and tooth alignment, which can lead to mismatch of tooth shape at both ends of the belt and affect the tooth joint at both ends of the belt.

[0028] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
