Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices, and in particular relates to a self-cleaning grinding wheel of a tire grinding device. Background Art

[0002] Tire grinding devices are essential equipment in tire production and repair. During the tire manufacturing process, the tire surface often needs to be ground to remove surface irregularities, burrs, and other defects, thereby achieving a higher level of flatness and finish, thereby improving tire performance and service life. Furthermore, during the tire repair process, the tire surface also needs to be ground to ensure better adhesion of the repair material to the tire surface. Traditional tire grinding devices typically include a rotating grinding wheel with a grinding material, such as sandpaper or a diamond coating, applied to the surface of the tire for grinding. However, during the grinding process, the friction between the grinding wheel and the tire surface generates a large amount of debris. If this debris is not removed promptly, it will reattach to the tire surface or enter the contact area between the grinding wheel and the tire, resulting in poor grinding results and possibly even damage to the grinding wheel or tire surface.

[0003] Although the design of self-cleaning grinding wheels has made certain progress, some problems still exist in practical applications: the brushes on traditional self-cleaning grinding wheels are usually fixed to the grinding wheel surface by simple insertion. During long-term use, due to the influence of vibration and impact, the brushes are easy to loosen or fall off, resulting in the failure of the self-cleaning function. The brushes on existing self-cleaning grinding wheels are often not evenly distributed, resulting in poor cleaning effect in some areas, especially in more complex areas of the tire surface, which are prone to leaving uncleaned debris. Although some designs use spiral grooves to help with chip removal, the actual chip removal effect is not ideal due to unreasonable groove design or improper brush arrangement. Especially during high-speed grinding, the debris is more likely to re-attach to the tire surface. Due to problems with the brush material and fixing method, existing self-cleaning grinding wheels are prone to wear after long-term use and need to be replaced frequently, increasing maintenance costs. Utility Model Content

[0004] In view of this, the utility model provides a self-cleaning grinding wheel for a tire grinding device, which solves the problem that the brush of a traditional grinding wheel is easily loosened or falls off, resulting in failure of the self-cleaning function, and improves the reliability and stability of the device.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a self-cleaning grinding wheel for a tire grinding device, comprising a grinding wheel, wherein the grinding wheel is provided with a plurality of brushes, the brushes being distributed along the circumferential direction of the grinding wheel, the grinding wheel being provided with a central axis, the central axis being in rotational fit with the grinding wheel, a bearing being provided between the central axis and the grinding wheel, the bearing being located at the inner center of the grinding wheel, the grinding wheel being provided with a fixing ring, the fixing ring surrounding the outer edge of the grinding wheel, the brushes being connected to holes on the surface of the grinding wheel through the fixing ring, and the fixing ring being used to fix the position of the brushes.

[0007] The self-cleaning grinding wheel for a tire grinding device provided by this utility model has the following technical effects: multiple fine brushes distributed along the circumference of the grinding wheel effectively remove debris generated during the grinding process, preventing debris from clogging the grinding wheel surface, thereby improving grinding efficiency and quality. The rotational coordination between the central shaft and the grinding wheel ensures smooth rotation, improving grinding uniformity and efficiency.

[0008] On the basis of the above technical solution, the self-cleaning grinding wheel of a tire grinding device of the present invention can also be improved as follows:

[0009] The brush is provided with a base, the base is provided with a conical structure, and the angle between the brush and the grinding wheel is 10° to 30°.

[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the conical structure ensures a firm connection between the brush and the grinding wheel, prevents the brush from loosening or falling off during use, and improves the safety and reliability of the device.

[0011] Furthermore, the outer surface of the grinding wheel is provided with at least one spiral groove, which extends from one end of the grinding wheel to the other end to form a spiral path running through the entire outer surface of the grinding wheel. The spiral groove is used to guide and discharge debris generated during the grinding process.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the design of the spiral groove enhances the discharge effect of debris, prevents debris blockage, and improves the grinding efficiency and quality.

[0013] Furthermore, the distribution density of the brush is at least 10 bristles per square centimeter.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are: the high-density brush distribution can ensure sufficient cleaning capacity, prevent debris clogging, and improve grinding efficiency and quality.

[0015] Furthermore, the length of the brush ranges from 1 mm to 5 mm, and the distance between the top of the brush and the outer surface of the grinding wheel does not exceed 2 mm.

[0016] The benefits of this improved solution include: a brush of appropriate length effectively removes debris without interfering with the grinding process, improving grinding uniformity and stability. Controlling the distance between the brush tip and the outer surface of the grinding wheel ensures the brush effectively removes debris, improving cleaning results.

[0017] Furthermore, the grinding wheel surface is provided with a hole, and the maximum diameter of the conical structure of the base is larger than the minimum diameter of the hole on the grinding wheel surface.

[0018] Furthermore, the fixing ring is an annular structure with a plurality of holes or slots provided thereon, wherein the holes or slots are arranged in a straight line or in a spiral shape, and the brush passes through the holes or slots and is fixed to the outer surface of the grinding wheel through the fixing ring.

[0019] The design of the fixing ring ensures that the position of the brush is fixed, preventing the brush (2) from loosening or falling off during use, thereby improving the reliability of the device.

[0020] Furthermore, the holes or notches on the fixing ring are arranged equidistantly along the circumference of the fixing ring, and the cross-section of the holes or notches of the fixing ring is an inverted L-shape, with the horizontal side of the inverted L-shape facing the base.

[0021] The beneficial effects of adopting the above-mentioned improved solution are: the design of the hole or slot ensures that the brush can pass through and be fixed on the fixing ring, thereby improving the reliability and stability of the device.

[0022] Furthermore, the brush is fixed to the hole on the surface of the grinding wheel by means of a snap, adhesive or threaded fixing method, so as to prevent the brush from falling off during use.

[0023] Furthermore, the fixing ring is made of elastic material, including silicone or rubber material.

[0024] The beneficial effect of adopting the above-mentioned improvement scheme is that the fixing ring made of elastic material allows the brush to move to a certain extent during the grinding process, thereby improving the stability and durability of the device.

[0025] Compared with the prior art, the self-cleaning grinding wheel of the tire grinding device provided by the present invention has the following beneficial effects:

[0026] Brush firmly fixed:

[0027] The conical structure at the base of the brush, inserted into the hole on the grinding wheel surface, ensures that the brush will not loosen or fall off during use. In addition, the brush is further fixed to the grinding wheel surface through the hole or notch on the retaining ring, improving the reliability and stability of the device.

[0028] Even distribution of brushes:

[0029] By optimizing the arrangement of the brushes, especially the spiral arrangement, the brushes are evenly distributed on the grinding wheel surface, which improves the debris removal effect, especially in the more complex areas of the tire surface.

[0030] Enhanced cleaning effect:

[0031] The combination of spiral grooves and the spiral arrangement of brushes not only effectively removes debris but also prevents it from reattaching to the tire surface. Furthermore, the cleaning effect is further enhanced by rationally designing the length and distribution density of the brushes.

[0032] Extended service life:

[0033] The brush is made of wear-resistant materials and is fixed with a conical structure and a fixed ring, which greatly increases the service life of the brush.

Specifically, the numerical parameters in this embodiment are selected within a higher range to ensure the excellent performance of the device under high-intensity use conditions.

[0076] Specific parameter settings

[0077] Brush Length:

[0078] The brush length is set at 5mm to ensure that the brush can effectively remove debris without interfering with the sanding process. This length is suitable for heavy sanding tasks and can effectively remove debris without interfering with the sanding process.

[0079] Brush distribution density:

[0080] The brush density is set at at least 20 per square centimeter to ensure sufficient cleaning capacity. This density ensures a high cleaning effect and prevents clogging by debris.

[0081] Grinding wheel diameter:

[0082] The grinding wheel diameter is set to 30cm to meet the grinding needs of larger tires. The larger diameter is suitable for large tires or large areas of grinding tasks.

[0083] Distance between brush tip and grinding wheel surface:

[0084] The distance between the tip of the brush and the outer surface of the grinding wheel is set to no more than 2mm to ensure the effective working range of the brush. This distance ensures good contact between the brush and the tire surface and improves the cleaning effect.

[0085] Angle between brush and grinding wheel:

[0086] like Figure 6 As shown, the brush-to-wheel angle is set at 30°. This refers to the angle of the brush relative to the normal (perpendicular to the grinding wheel surface) of the grinding wheel to optimize the chip removal path. This angle is suitable for heavy grinding tasks and can effectively guide the chip removal.

[0087] Taper of conical structure:

[0088] The tapered structure has a taper of 1:30, ensuring that the brush is firmly fixed in place through a tapered fit after being inserted into the hole. This taper provides a stronger hold and is suitable for intensive use.

[0089] Specifically, the principle of the present utility model is:

[0090] Brush fixing principle:

[0091] The brush has a tapered structure at its base that inserts into a hole in the grinding wheel surface. The maximum diameter of the tapered structure is larger than the minimum diameter of the hole, ensuring that the brush is securely fixed to the grinding wheel once inserted. Furthermore, the brush is further secured by holes or notches in the retaining ring, enhancing the stability of the device.

[0092] Brush arrangement principle:

[0093] The brushes are arranged in a spiral pattern and fixed to the grinding wheel surface through holes or slots in the retaining ring. This spiral arrangement not only improves debris removal but also prevents debris from reattaching to the tire surface. The brush density is at least 10 per square centimeter, ensuring sufficient cleaning capacity.

[0094] Spiral groove design principle:

[0095] The grinding wheel is designed with spiral grooves, which, combined with the spiral arrangement of the brushes, effectively remove the debris generated during the grinding process. The spiral groove design not only enhances the removal of debris, but also improves the self-cleaning ability of the device.

[0096] Conical structure design principle:

[0097] The tapered structure allows the brush to be better secured in the hole by expanding the tapered portion when inserted. The maximum diameter of the tapered structure is larger than the minimum diameter of the hole, ensuring that the brush will not fall out easily after insertion. In addition, the material of the tapered structure has a certain degree of elasticity, allowing the brush to deform appropriately when inserted into the hole, ensuring a better fixation effect.

[0098] Elastic design principle of retaining ring:
