Description

Technical Field

[0001] This utility model relates to the field of belt alignment technology, specifically an adjustable belt alignment device for sanders. Background Technology

[0002] During the operation of a sander, the sanding belt, as the core grinding component, directly affects the processing accuracy and surface quality. However, when the sanding belt is running at high speed, it is prone to lateral displacement due to factors such as installation errors, uneven tension, and material force deviation.

[0003] Various belt correction devices have emerged in the existing technology, but they generally have some shortcomings. Traditional correction structures have poor adjustment flexibility, and the contact between the correction components and the sanding belt is mostly rigid friction, which not only easily causes damage to the edge of the sanding belt, but also makes it difficult to accurately adjust the correction force according to the width or offset of the sanding belt, resulting in poor correction effect and inability to adapt to the operation requirements of different specifications of sanding belts, thus affecting the consistency and reliability of sanding. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an adjustable belt correction device for sanders, which solves the problem of poor adjustment flexibility of traditional correction structures.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: An adjustable belt alignment device for a sander includes: a base structure, a support structure symmetrically and slidably connected to the inner wall of the top of the base structure, a roller structure slidably connected to the inner wall of the support structure, and an alignment structure slidably connected to the inner wall of the side of the support structure; the alignment structure includes a bidirectional threaded rod, a limit plate symmetrically and fixedly connected to the outer wall of the bidirectional threaded rod, a rotating rod fixedly connected to the outer wall of the bidirectional threaded rod, a guide plate symmetrically and threadedly connected to the outer wall of the bidirectional threaded rod, an alignment plate fixedly connected to the outer wall of the top of the guide plate, and an alignment wheel rotatably connected to the inner wall of the alignment plate.

[0006] Preferably, the base structure includes a base, the outer wall of the top of the base is symmetrically provided with sliding grooves, and the outer wall of the top of the base is provided with threaded holes, the threaded holes being threaded with bolts for connection and fixation.

[0007] Preferably, the support structure includes a support plate, with sliders symmetrically fixedly connected to the outer wall of the bottom of the support plate, bearings fixedly connected to the inner wall of the support plate, the inner wall of the bearings having toothed grooves, and slots being formed on the outer wall of the side of the support plate.

[0008] Preferably, the roller structure includes a support roller, the outer wall of which is fixedly connected with an anti-slip sleeve, and the outer wall of the side of the support roller is symmetrically fixedly connected with a rotating shaft, the outer wall of which is fixedly connected with a toothed rod.

[0009] Preferably, the outer wall of the slider is slidably connected to the inner wall of the groove, the support plate is fixed to the base by bolts and threaded connection to the inner wall of the threaded hole, the inner wall of the tooth groove is slidably connected to the outer wall of the tooth rod, and the support plates are symmetrically arranged on both sides of the support roller. The roller structure is rotated by bearings inside the symmetrically installed support structure.

[0010] Preferably, the outer wall of the bidirectional threaded rod is slidably connected to the inner wall of the slot, and the outer wall of the limiting plate is slidably connected to the outer wall of the support plate. The outer wall of the guide plate is slidably connected to the outer wall of the anti-slip sleeve. When the rotating rod is rotated, it will drive the bidirectional threaded rod to rotate. Since the two ends of the bidirectional threaded rod have opposite thread directions and the outer wall is symmetrically threaded with guide plates, when the bidirectional threaded rod rotates, the two guide plates will move in opposite directions synchronously along their axes, moving closer or further away.

[0011] (III) Beneficial Effects This invention provides an adjustable belt alignment device for sanders. It offers the following advantages: (i) The base structure achieves the positioning of the support structure through the sliding fit of the sliding groove and the slider, and then the fixing method of bolts and threaded holes ensures that the support structure is firmly installed. The assembly of each component of the device is achieved through sliding fit and bolt fixing, with bidirectional threaded rod and slot, toothed rod and toothed groove. The installation process is simple and easy to understand, which facilitates quick assembly or disassembly and reduces the equipment failure rate and maintenance cost.

[0012] (ii) This correction structure can drive the correction wheel to contact the edge of the sanding belt by rotating the rotating rod. By utilizing the rotational characteristics of the correction wheel, friction damage with the sanding belt is reduced, and a stable lateral thrust is applied to the misaligned sanding belt to quickly guide the sanding belt back to its original position. At the same time, the tight contact between the anti-slip sleeve and the sanding belt further reduces the probability of the sanding belt deviating during operation, ensuring the flatness and consistency of the sanding surface and improving the processing quality.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an adjustable belt correction device for a sander, comprising: a base structure 1, a support structure 2 symmetrically and slidably connected to the inner wall of the top of the base structure 1, a roller structure 3 slidably connected to the inner wall of the support structure 2, and a correction structure 4 slidably connected to the inner wall of the side of the support structure 2; the correction structure 4 includes a bidirectional threaded rod 41, a limit plate 42 symmetrically and fixedly connected to the outer wall of the bidirectional threaded rod 41, a rotating rod 43 fixedly connected to the outer wall of the bidirectional threaded rod 41, a guide plate 44 symmetrically and threadedly connected to the outer wall of the bidirectional threaded rod 41, a correction plate 45 fixedly connected to the outer wall of the top of the guide plate 44, and a correction wheel 46 rotatably connected to the inner wall of the correction plate 45.

[0017] The base structure 1 includes a base 11. The outer wall of the top of the base 11 is symmetrically provided with sliding grooves 12. The outer wall of the top of the base 11 is provided with threaded holes 13. Bolts are threaded into the threaded holes 13 for connection and fixation.

[0018] The support structure 2 includes a support plate 21. A slider 22 is symmetrically fixedly connected to the outer wall of the bottom of the support plate 21. A bearing 23 is fixedly connected to the inner wall of the support plate 21. A toothed groove 24 is opened on the inner wall of the bearing 23. A slot 25 is opened on the outer wall of the side of the support plate 21.

[0019] The roller structure 3 includes a support roller 31, an anti-slip sleeve 32 is fixedly connected to the outer wall of the support roller 31, a rotating shaft 33 is symmetrically fixedly connected to the outer wall of the side of the support roller 31, and a toothed rod 34 is fixedly connected to the outer wall of the rotating shaft 33.

[0020] The outer wall of the slider 22 is slidably connected to the inner wall of the groove 12. The support plate 21 is fixed to the base 11 by bolts and threaded connection to the inner wall of the threaded hole 13. The inner wall of the tooth groove 24 is slidably connected to the outer wall of the tooth bar 34. The support plate 21 is symmetrically arranged on both sides of the support roller 31. The roller structure 3 is rotated inside the symmetrically installed support structure 2 by bearing 23.

[0021] The outer wall of the bidirectional threaded rod 41 is slidably connected to the inner wall of the slot 25, and the outer wall of the limiting plate 42 is slidably connected to the outer wall of the support plate 21. The outer wall of the guide plate 44 is slidably connected to the outer wall of the anti-slip sleeve 32. When the rotating rod 43 is rotated, it will drive the bidirectional threaded rod 41 to rotate. Since the threads at both ends of the bidirectional threaded rod 41 are opposite in direction and the guide plates 44 are symmetrically threaded on the outer wall, when the bidirectional threaded rod 41 rotates, the two guide plates 44 will move in opposite directions synchronously along their axes, moving closer or further away.

[0022] In use, the base structure 1 serves as the installation foundation. The symmetrically installed support structure 2 rotates the roller structure 3 through the bearing 23 inside. The sanding belt is sleeved on the outside of the roller structure 3. The sanding belt is driven to slide by the drive roller on the sander, which also drives the roller structure 3 to rotate. The correction structure 4 ensures the position of the sanding belt and can flexibly adjust the distance and position of the two correction wheels 46. During installation, the two symmetrical support plates 21 are initially fixed by sliding the groove 12 at the top of the base 11 and the slider 22 at the bottom of the support structure 2. They are then fixed by bolts and threaded holes 13. Before the support plates 21 are fixed, the toothed rod 34 on the rotating shaft 33 and the toothed groove 24 in the bearing 23 are slidably connected, which can limit the axial displacement of the support roller 31 and ensure its stability. At the same time, the roller structure 3 is connected to the support structure 2. After the support structure 2 and the roller structure 3 are fixed, the bidirectional threaded rod 41 is slidably inserted into the slot 25. The lateral sliding of the bidirectional threaded rod 41 is restricted by the limiting plate 42. At the same time, the outer wall of the guide plate 44 contacts the anti-slip sleeve 32 outside the support roller 31. At this time, the device is installed. The reverse is also true. After installation, the operator can rotate the rotating rod 43 to drive the bidirectional threaded rod 41 to rotate. Since the threads at both ends of the bidirectional threaded rod 41 are opposite in direction and the guide plates 44 are symmetrically threaded on the outer wall, when the bidirectional threaded rod 41 rotates, the two guide plates 44 will move in opposite directions synchronously along its axis, moving closer or further away. The correction plate 45 on the top of the guide plate 44 moves with the guide plate 44, driving the correction wheel 46 connected to the inner wall to move synchronously. When the sanding belt deviates to one side, the correction wheel 46 on the deviated side is adjusted to contact the edge of the sanding belt. The rotation of the correction wheel 46 applies a lateral thrust to the sanding belt. By adjusting the distance and position of the two correction wheels 46, it can adapt to sanding belts of different widths and precisely control the correction force according to the degree of deviation, achieving efficient correction. When the drive roller on the sander drives the sanding belt to slide, the anti-slip sleeve 32 drives the support roller 31. The axial positioning of the toothed rod 34 on the rotating shaft 33 and the toothed groove 24 in the bearing 23 causes the support roller 31 to rotate. When the sanding belt slides, it is restricted by the correction wheel 46 to avoid deviation.
