Description

Technical Field

[0001] This utility model relates to the technical field of tire auxiliary processing devices, specifically to a device for precisely cutting tire hairs one by one. Background Technology

[0002] During tire manufacturing, pores in the vulcanizing mold leave needle-like hairs on the tire tread and sidewalls. In the laboratory, the consistency of these hair lengths significantly impacts experimental accuracy, such as in friction coefficient testing. However, manual hair removal not only easily scratches the tire surface but also results in inconsistent hair lengths, affecting the tire's appearance and quality. To address this issue, engineers have made various attempts. For example, Chinese patent CN112476899A discloses a tire hair removal device with a protective cover, which achieves rapid tire hair removal through the cooperation of a central shaft, cutters, and an opening and closing motor. However, this solution still has drawbacks: it cannot precisely cut individual hairs, and the height control is not precise enough to meet specific experimental requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a device for precise cutting of tire hairs one by one.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A device for precisely cutting tire hairs one by one includes a tire body and a number of tire hairs remaining on the tire body. A cutting device is disposed on the outer side of the tire body. The cutting device includes a downward-facing cylindrical body, and a cutting mechanism, a laser distance-fixing mechanism, a height adjustment mechanism, and a buffer mechanism disposed on the cylindrical body.

[0006] The cutting mechanism includes an electric cylinder and a cutting tool driven by the electric cylinder; the electric cylinder is located on the side of the cylindrical body, and the cutting tool penetrates the cylindrical body and extends to the inner hair area.

[0007] A laser ranging mechanism, including a laser ranging sensor, is disposed on the top of a cylindrical body and faces the surface of the tire body;

[0008] The height adjustment mechanism includes a track and a slider. A cutting mechanism is installed on the slider. The slider moves up and down along the track to adjust the cutting distance between the cutting blade and the tire body. The cutting distance determines the degree of tire hair residue.

[0009] The buffer mechanism includes an annular buffer pad fitted onto the end of the cylindrical body, and the buffer mechanism abuts against the tire body; tire hairs enter the cavity of the cylindrical body from the buffer mechanism.

[0010] This technical solution utilizes a cutting mechanism, a laser distance-fixing mechanism, a height adjustment mechanism, and a buffer mechanism to allow for precise cutting of individual tire hairs at varying heights, meeting diverse experimental needs. Specifically, an electric cylinder connected to a power source drives the cutting blade to extend and retract during cutting. The material and shape of the cutting blade are selected based on experimental requirements, typically using high-speed steel, cemented carbide, or ceramic tips. The laser distance-fixing sensor measures distance using the reflection principle of a laser beam. When the laser beam illuminates the tire surface, the reflected light is received by the sensor and converted into an electrical signal. The control mechanism determines the distance by judging the round-trip time or phase difference of the laser beam. The design of the track and slider allows for precise vertical movement of the cutting mechanism. The height of the cutting blade can be manually adjusted to accommodate unevenness on different tire surfaces. The material selection for the annular buffer pad must consider its elasticity, wear resistance, and corrosion resistance, helping to reduce the direct impact between the cutting blade and the tire during cutting and protecting the tire from damage.

[0011] In addition, the tire hair cutting device for precise individual cutting proposed in this utility model may also have the following additional technical features:

[0012] According to one embodiment of the present invention, the diameter of the cylindrical body is larger than the diameter of the fetal hair.

[0013] This technical solution ensures that the diameter of the cylindrical body is larger than the diameter of the fetal hair, so that the fetal hair can smoothly enter the cavity of the cylindrical body for cutting.

[0014] According to one embodiment of the present invention, the top of the cylindrical body is provided with a connecting rod that is connected to the robotic arm.

[0015] This technical solution improves cutting efficiency by setting a connecting rod at the top of the cylindrical body that is connected to a robotic arm, thereby enabling automated operation and movement of the cutting device.

[0016] According to one embodiment of the present invention, the cutting device is also connected to a control mechanism, which includes a controller that is electrically connected to a laser distance sensor, an electric cylinder, and a robotic arm.

[0017] This technical solution connects the cutting device with a control mechanism, including a controller, a laser distance sensor, an electric cylinder, and a robotic arm, to achieve precise adjustment of the cutting process.

[0018] According to one embodiment of the present invention, the height adjustment mechanism further includes a locking bolt located on the side of the slider, which fixes the slider and the track to each other.

[0019] This technical solution adds a locking bolt to the height adjustment mechanism to fix the relative position of the slider and the track when needed, ensuring the accuracy and stability of the cutting distance.

[0020] According to one embodiment of the present invention, the track is vertically arranged at the bottom of the cylindrical body, and the track side is provided with a scale.

[0021] This technical solution provides an intuitive visual reference by setting graduations on the side of the track, which helps to adjust the height of the cutting tool more accurately during the experiment.

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] The cutting mechanism, laser distance setting mechanism, height adjustment mechanism, and buffer mechanism allow for adjustments to the cutting mechanism at different heights, enabling precise cutting of individual fetal hairs to meet various experimental needs. Attached Figure Description

[0028] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1 to 3 As shown, this embodiment provides a device for precisely cutting tire hairs one by one, including a tire body 1 and a number of tire hairs 2 remaining on the tire body 1. A cutting device is provided on the outer side of the tire body 1. The cutting device includes a cylindrical body 3 with the opening facing downward, and a cutting mechanism 4, a laser distance fixing mechanism 5, a height adjustment mechanism 7, and a buffer mechanism 8 disposed on the cylindrical body 3, wherein:

[0031] The cutting mechanism 4 includes an electric cylinder and a cutting tool driven by the electric cylinder; the electric cylinder is located on the side of the cylindrical body 3, and the cutting tool penetrates the cylindrical body 3 and extends to the inner hair 2.

[0032] The laser ranging mechanism 5 includes a laser ranging sensor, which is disposed on the top of the cylindrical body 3 and faces the surface of the tire body 1;

[0033] The height adjustment mechanism 7 includes a track and a slider. A cutting mechanism 4 is installed on the slider. The slider moves up and down along the track to adjust the cutting distance between the cutting blade and the tire body 1. The cutting distance determines the degree of residual tire hair 2.

[0034] The buffer mechanism 8 includes an annular buffer pad, which is fitted onto the port of the cylindrical body 3, and the buffer mechanism 8 abuts against the tire body 1; the tire hair 2 enters the cavity of the cylindrical body 3 from the buffer mechanism 8.

[0035] like Figures 1 to 3 As shown, this technical solution, through the cutting mechanism 4, laser distance-fixing mechanism 5, height adjustment mechanism 7, and buffer mechanism 8, allows for the adjustment of the cutting mechanism 4 at different heights, achieving precise cutting of a single tire hair 2 to meet different experimental needs. Specifically, the electric cylinder is connected to the power supply to drive the cutting blade to extend and retract for cutting; the material and shape of the cutting blade are selected according to the experimental needs, typically using high-speed steel, cemented carbide, or ceramic blades; the laser distance-fixing sensor uses the reflection principle of the laser beam to measure distance. When the laser beam irradiates the surface of the tire body 1, the reflected light is received by the sensor and converted into an electrical signal. The distance is determined by judging the round-trip time or phase difference of the laser beam through the control mechanism; the design of the track and slider allows the cutting mechanism 4 to move precisely in the vertical direction; the height of the cutting blade can be manually adjusted to adapt to different unevenness of the tire body 1 surface; the material selection of the annular buffer pad must consider its elasticity, wear resistance, and corrosion resistance, which helps to reduce the direct impact between the cutting blade and the tire body 1 during the cutting process and protect the tire body 1 from damage.

[0036] In addition, the tire hair cutting device for precise individual cutting proposed in this utility model may also have the following additional technical features:

[0037] According to one embodiment of the present invention, the diameter of the cylindrical body 3 is larger than the diameter of the fetal hair 2.

[0038] This technical solution ensures that the diameter of the cylindrical body 3 is larger than the diameter of the fetal hair 2, so that the fetal hair 2 can smoothly enter the cavity of the cylindrical body 3 for cutting.

[0039] According to one embodiment of the present invention, the top of the cylindrical body 3 is provided with a connecting rod 6 that is connected to the robotic arm.

[0040] This technical solution achieves automated operation and movement of the cutting device and improves cutting efficiency by setting a connecting rod 6 connected to a robotic arm at the top of the cylindrical body 3.

[0041] According to one embodiment of the present invention, the cutting device is also connected to a control mechanism, which includes a controller that is electrically connected to a laser distance sensor, an electric cylinder, and a robotic arm.

[0042] This technical solution connects the cutting device with a control mechanism, including a controller, a laser distance sensor, an electric cylinder, and a robotic arm, to achieve precise adjustment of the cutting process.

[0043] According to one embodiment of the present invention, the height adjustment mechanism 7 further includes a locking bolt, which is located on the side of the slider and fixes the slider and the track to each other by means of the locking bolt.

[0044] This technical solution adds a locking bolt to the height adjustment mechanism 7 to fix the relative position of the slider and the track when needed, ensuring the accuracy and stability of the cutting distance.

[0045] According to one embodiment of the present invention, the track is vertically arranged at the bottom of the cylindrical body, and the track side is provided with a scale.

[0046] This technical solution provides an intuitive visual reference by setting graduations on the side of the track, which helps to adjust the height of the cutting tool more accurately during the experiment.

[0047] The usage process of the above embodiments is as follows:

[0048] like Figures 1 to 3 As shown, the height of the cutting mechanism 4 is manually adjusted to achieve the preset cutting distance between the cutting blade and the tire body 1. During the adjustment process, the scale on the side of the track can be observed to ensure accuracy. After the height of the cutting blade is adjusted, the locking bolts fix the slider and the track to each other, ensuring the stability and accuracy of the cutting distance. The laser distance sensor emits a laser beam toward the surface of the tire body 1 to measure the distance between the tire body 1 and the cutting blade, and converts this distance information into an electrical signal that is transmitted to the control mechanism. The electric cylinder is connected to the power supply and started, driving the cutting blade to extend and retract to cut the tire hairs 2. The material and shape of the cutting blade are selected according to the experimental requirements to ensure cutting efficiency and cutting quality.

[0049] The annular buffer pad in the buffer mechanism 8 abuts against the tire body 1, reducing the direct impact between the cutting tool and the tire body 1 during the cutting process and protecting the tire body 1 from damage; the tire hairs 2 smoothly enter the cavity of the cylindrical body 3 through the buffer mechanism 8 and are precisely cut one by one by the cutting tool.

[0050] It should be noted that this invention only improves the hardware structure and does not improve the detection principle of the laser distance sensor, i.e., it does not improve the software algorithm. Furthermore, this invention sacrifices cutting efficiency for improved cutting accuracy.

[0051] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, it is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention.

Therefore, the protection scope of the present invention should be determined by the scope of the claims.
