Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically a tire hair trimming mechanism. Background Technology

[0002] Tires are annular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, making contact with the road surface, and ensuring the vehicle's driving performance. During the high-pressure, high-temperature molding process of tires, excess rubber is squeezed out from the vent holes, forming common small burrs. Therefore, these burrs on the tire's outer sidewall need to be scraped off.

[0003] For example, patent CN112171984A discloses a tire hair removal tool, including a support frame, a tripod, a groove, a roller screw, a bearing, a roller, a handle screw, a sponge handle, and a removal part. The support frame is long and rod-shaped, with a vertical tripod fixed to its upper end. Both the support frame and the tripod are made of stainless steel, and a horizontal groove runs through each of the two support frames in the front-to-back direction. This invention has a simple structure and is easy to operate. The use of a support frame and tripod made of high-quality stainless steel can greatly extend the service life of the invention. The roller screw, which allows for adjustable spacing, can accommodate tires of various diameters, thus saving material waste. The use of left and right adjustable screws allows for adjustment of the horizontal position and angle of the razor, thereby achieving a good tire hair removal effect.

[0004] While the tire hair removal tool in the aforementioned patent is practical and convenient, it also has its shortcomings. Typically, tire hair is removed by rotating the tire and fixing the blade on the tire surface to cut the hair. Due to the softness of the tire hair and the fatigue and dulling of the cutting shears, when the blade cuts the hair, the side of the hair away from the blade is not supported, and the hair is prone to bending and deformation instead of being cut off, resulting in some hair being missed or not completely cut off. Utility Model Content

[0005] The purpose of this invention is to provide a tire hair trimming mechanism to address the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The tire hair trimming mechanism includes a mounting box, a first cutter, a second cutter, a swinging component, and a transmission assembly. The first cutter and the second cutter are reciprocally and horizontally slidably connected in the mounting box, and the sliding directions of the first cutter and the second cutter are opposite. The swinging component is oscillatingly connected in the mounting box. When the swinging component oscillates, the transmission assembly drives the first cutter and the second cutter to reciprocate and slide horizontally to cut the tire hair.

[0007] Furthermore, the transmission assembly includes two cylinders. A connecting plate is provided on one side of both the first cutter and the second cutter. A guide member is provided on one side of both connecting plates. The two guide members provide guidance for the movement paths of the first cutter and the second cutter, respectively. A cylinder is provided on the other side of both the first cutter and the second cutter. Two grooves are symmetrically opened on one side of the swing member. The two cylinders and the two grooves are slidably connected in a one-to-one correspondence.

[0008] Furthermore, both of the guide components include a slider and a guide rod. The slider is slidably sleeved on the guide rod, and the guide rod is horizontally disposed inside the mounting box. The two sliders are fixedly connected to one side of the two connecting plates.

[0009] Furthermore, a buffer spring is provided between each end of the slider and the mounting box, and both buffer springs are sleeved on the guide rod.

[0010] Furthermore, a sliding rod is horizontally reciprocatingly connected inside the mounting box, and a linkage component is provided between the sliding rod and the swinging component. When the sliding rod reciprocates, the swinging component is driven to swing through the linkage component.

[0011] Furthermore, the linkage component includes a sleeve, the sliding rod is reciprocatingly and horizontally slidably connected inside the sleeve, the sliding rod is provided with a protrusion, a spiral groove is opened inside the sleeve, the protrusion is slidably connected inside the spiral groove, one end of the sleeve is coaxially and fixedly connected to the swinging component, and an electric push rod is provided on one side of the mounting box, the output end of the electric push rod is fixedly connected to one end of the sliding rod.

[0012] Furthermore, a retaining ring is provided at the end of the sleeve away from the swinging component, and a positioning groove is provided on the inner wall of the mounting box, with the retaining ring rotatably connected in the positioning groove.

[0013] Furthermore, the blades of both the first and second cutters are serrated.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Please see Figure 1-6 This utility model provides a technical solution: a tire hair trimming mechanism includes a mounting box 1, a first cutter 2, a second cutter 3, a swinging member 8, and a transmission assembly. The first cutter 2 and the second cutter 3 are reciprocatingly and horizontally slidably connected within the mounting box 1, and their sliding directions are opposite. The swinging member 8 is oscillatingly connected within the mounting box 1. When the swinging member 8 oscillates, the transmission assembly drives the first cutter 2 and the second cutter 3 to reciprocate and slide horizontally to cut the tire hair. Preferably, a collection box can be provided below the mounting box 1 to collect the cut tire hair.

[0020] In this embodiment, the transmission assembly includes two cylinders 10. A connecting plate 4 is provided on one side of the first cutter 2 and the second cutter 3. A guide member is provided on one side of each connecting plate 4. The two guide members provide guidance for the movement paths of the first cutter 2 and the second cutter 3, respectively. A cylinder 10 is provided on the other side of the first cutter 2 and the second cutter 3. Two grooves 9 are symmetrically opened on one side of the swing member 8. The two cylinders 10 and the two grooves 9 are slidably connected in a one-to-one correspondence. Specifically, by rotating the swing member 8, the position of the grooves 9 changes accordingly. As the two grooves 9 gradually tilt, it forces the cylinders 10 to move along the trajectory of the corresponding grooves 9. However, since the guide member guides and limits the movement direction of the connecting plate 4, the sliding of the cylinders 10 in the grooves 9 drives the first cutter 2 and the second cutter 3 to slide in opposite directions, forming a cut to shear the tire hair.

[0021] In this embodiment, each of the two guide components includes a slider 5 and a guide rod 6. The slider 5 is slidably sleeved on the guide rod 6, and the guide rod 6 is horizontally arranged in the mounting box 1. The two sliders 5 are fixedly connected to one side of the two connecting plates 4. Specifically, through the cooperation between the guide rod 6 and the slider 5, the movement path of the two connecting plates 4 is guided, so that the first cutter 2 and the second cutter 3 can only move in a straight line.

[0022] In this embodiment, a buffer spring 7 is provided between each end of the slider 5 and the mounting box 1, and both buffer springs 7 are sleeved on the guide rod 6. Specifically, the buffer springs 7 play a buffering role on the first cutter 2 and the second cutter 3 to prevent the first cutter 2 and the second cutter 3 from colliding with the inner wall of the mounting box 1, generating vibration, and affecting the shearing effect.

[0023] In this embodiment, a sliding rod 13 is horizontally reciprocatingly slidably connected inside the mounting box 1, and a linkage assembly is provided between the sliding rod 13 and the swing member 8. When the sliding rod 13 reciprocates, the linkage assembly drives the swing member 8 to swing. The linkage assembly includes a sleeve 11, and the sliding rod 13 is horizontally reciprocatingly slidably connected inside the sleeve 11. A protrusion 14 is provided on the sliding rod 13, and a spiral groove 12 is formed inside the sleeve 11. The protrusion 14 is slidably connected inside the spiral groove 12, and one end of the sleeve 11 is coaxially fixed with the swing member 8. A fixed connection is provided on one side of the mounting box 1, and an electric push rod 16 is fixedly connected to one end of the sliding rod 13. Specifically, when the electric push rod 16 is started, the sliding rod 13 is driven to reciprocate within the sleeve 11. The sliding rod 13 drives the protrusion 14 to move from one end of the spiral groove 12 to the other end, driving the sleeve 11 to rotate at a certain angle. Then the sliding rod 13 moves in the opposite direction, driving the sleeve 11 to rotate in the opposite direction, so that the sleeve 11 drives the swinging member 8 to swing, thereby realizing the first cutter 2 and the second cutter 3 cutting the tire hair.

[0024] It should be noted that the specific model and specifications of the electric actuator 16 need to be selected and determined according to the actual specifications of the device, so its control method and wiring layout will not be described in detail.

[0025] In this embodiment, a retaining ring 15 is provided at the end of the sleeve 11 away from the swing member 8. A positioning groove is provided on the inner wall of the mounting box 1. The retaining ring 15 is rotatably connected in the positioning groove. Specifically, through the cooperation between the retaining ring 15 and the positioning groove, the rotation axis of the sleeve 11 coincides with the rotation axis of the swing member 8, and the position of the sleeve 11 is limited to prevent the sleeve 11 from displacing in the length direction of the sliding rod 13.

[0026] In this embodiment, the blades of the first cutter 2 and the second cutter 3 are both serrated. Specifically, the serrated blades can effectively grip and fix the baby hair, preventing it from slipping during the cutting process and ensuring that the baby hair is accurately fed between the first cutter 2 and the second cutter 3 for cutting.

[0027] Working principle: This tire hair trimming mechanism starts by activating the electric push rod 16, which drives the sliding rod 13 to reciprocate within the sleeve 11. The sliding rod 13 drives the protrusion 14 from one end of the spiral groove 12 to the other end, causing the sleeve 11 to rotate at a certain angle. Then, the sliding rod 13 moves in the opposite direction, causing the sleeve 11 to rotate in the opposite direction, thus enabling the sleeve 11 to drive the swinging member 8 to swing. During the swinging process of the swinging member 8, the position of the groove 9 changes accordingly. As the two grooves 9 gradually tilt, it forces the cylinder 10 to move along the trajectory of the corresponding groove 9. However, due to the guide member guiding and limiting the movement direction of the connecting plate 4, the sliding of the cylinder 10 within the groove 9 drives the first cutter 2 and the second cutter 3 to slide in opposite directions, forming a cut to shear the tire hair. The cutting process mainly occurs within the semi-enclosed environment formed by the blades of the first cutter 2 and the second cutter 3. The tire hair is cut from both sides simultaneously, and both sides of the tire hair are subjected to shearing force, making the shearing force more symmetrical and avoiding missed cuts or incomplete cutting.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
