Description

Technical Field

[0001] This utility model belongs to the field of tire manufacturing technology, specifically relating to a device for repairing finished engineering tires. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] The finished engineering radial tires, vulcanized in a vulcanizing machine, are large in size and weight. Tires produced using existing processes often have numerous rubber burrs and rough edges. After passing X-ray non-destructive testing, these burrs need to be trimmed and removed using tools such as rakes, and the tires must be inspected for defects. Personnel must rotate the tire to perform comprehensive trimming of the rubber burrs and rough edges and to inspect the exterior and interior for any flaws. Once the trimming and inspection are passed, the tire proceeds to the next process: a release agent is sprayed onto the engineering tire, followed by the assembly of the inner liner, and finally, the tire is packaged and stored. Tires that fail the inspection are sent to a processing area.

[0004] Because finished engineering tires are heavy and bulky, traditional trimming equipment is unsuitable. There is a need to address the difficulties of rotating and moving tires during manual trimming and inspection, resulting in high labor intensity. Currently, there are devices available for engineering tire trimming, but the stability of the tire is difficult to guarantee, especially when rotating the tire to change its trimming position, causing it to wobble and requiring manual straightening, leading to low trimming efficiency. Furthermore, the rubber fibers and burrs on engineering tires are distributed in various locations, making them easy to miss during trimming. If the tire fails inspection, it needs to be reworked, which is time-consuming and labor-intensive. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a finished engineering tire repair device that can ensure the stability of the engineering tire during repair and ensure that the rubber burrs and rough edges on the engineering tire are thoroughly repaired after one repair, thereby ensuring repair efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A finished engineering tire repair device includes a pit, in which a drive mechanism is installed. The drive mechanism is connected to a roller assembly, which includes a first roller and a second roller. The first roller is horizontally arranged, with its upper surface flush with the ground and its upper part tangentially contacting the bottom of the finished engineering tire. The upper end of the pit is covered with a patterned steel plate, and an opening is left at the upper end of the first roller. A frame is provided at the upper end of the patterned steel plate, and second rollers are provided at both ends of the frame. The second rollers are vertically arranged, and their sides are spaced apart from the sides of the finished engineering tire.

[0007] As a further technical solution, the drive mechanism includes a motor, a motor reducer, a coupling, a sprocket, a chain, and bearings. The output end of the motor is connected to one end of the motor reducer, and the other end of the motor reducer is connected to one end of the coupling.

[0008] As a further technical solution, the other end of the coupling is connected to the first roller, and bearings are provided at both ends of the first roller, with several first rollers spaced apart.

[0009] As a further technical solution, a sprocket is fitted onto the output end of the coupling, a chain is mounted on the sprocket, and a number of sprockets are spaced apart at one end of the chain, with the number of sprockets connected to a number of first rollers.

[0010] As a further technical solution, several second rollers are spaced apart at both ends of the frame, and the second rollers are rotatably connected to the frame.

[0011] As a further technical solution, the top of the frame is provided with LED strip lights, and several LED strip lights are arranged at intervals; the two ends of the front of the frame are provided with extended universal lamp heads.

[0012] As a further technical solution, a start / stop / emergency stop button box is provided at the lower part of the extended universal lamp head, and the start / stop / emergency stop button box is mounted on the frame; a warning tri-color light is installed at the lower part of the LED strip lighting, and the warning tri-color light is mounted on the frame.

[0013] As a further technical solution, a start foot pedal is provided at both ends of the front part of the patterned steel plate, and a stop foot pedal is provided at one end of the start foot pedal; both the start foot pedal and the stop foot pedal are installed on the patterned steel plate.

[0014] As a further technical solution, a detection photoelectric sensor is provided on one side of the frame.

[0015] As a further technical solution, a power distribution box is provided at one end of the patterned steel plate. The power distribution box is electrically connected to the drive mechanism, start foot pedal, stop foot pedal, detection photoelectric device, extended universal lamp head, LED strip lighting, start / stop emergency stop button box, and warning tri-color lamp.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are: This invention features several first rollers spaced apart within a pit, their upper surfaces flush with the ground. The upper parts of these rollers directly contact the bottom of the finished engineering tire, and their synchronous rotation, driven by a drive mechanism, provides stable circumferential motion power to the tire, replacing the laborious manual rotation. Several second rollers, spaced apart at both ends of the frame, are spaced from the tire's side and are rotatably connected to the frame. When the tire tilts, these second rollers contact the tire, assisting in its rotation and facilitating adjustment by the operator. This ensures the tire remains stable throughout the trimming and inspection process, providing a safe and stable working foundation for the operator.

[0017] The utility model features a series of LED strip lights spaced at intervals on the top of the frame, forming a uniform overhead main light source. This light covers the entire tire repair area, clearly revealing most of the tire's rubber, burrs, and surface imperfections, providing basic illumination for operators and preventing blind spots caused by dim ambient light. The extended omnidirectional light heads at both ends of the front of the frame are flexibly adjustable, allowing operators to adjust the light head orientation as needed for different tire locations, achieving precise supplemental lighting in specific areas.

[0018] By combining LED strip lights and extended omnidirectional lights, not only are the light and shadow on the tire surface eliminated, but the fine rubber burrs and rough edges distributed in various positions are also clearly highlighted. This ensures that operators do not miss any during the trimming process, reduces the rework rate caused by missing burrs or incomplete inspection, and improves the quality and efficiency of tire repair.

Detailed Implementation

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] Because finished engineering tires are heavy and bulky, traditional trimming equipment is unsuitable. There is a need to address the difficulties of rotating and moving tires during manual trimming and inspection, resulting in high labor intensity. Currently, there are devices available for engineering tire trimming, but the stability of the tire is difficult to guarantee, especially when rotating the tire to change its trimming position, causing it to wobble and requiring manual straightening, leading to low trimming efficiency. Furthermore, the rubber fibers and burrs on engineering tires are distributed in various locations, making them easy to miss during trimming. If the tire fails inspection, it needs to be reworked, which is time-consuming and labor-intensive.

[0023] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a finished engineering tire repair device, such as... Figure 1 As shown, the system includes a pit 111, in which a drive mechanism is installed. The drive mechanism is connected to a roller assembly, which includes a first roller 6 and a second roller 12. The first roller 6 is horizontally arranged, with its upper surface flush with the ground. The upper part of the first roller 6 is tangentially in contact with the bottom of the finished engineering tire 101. The upper end of the pit 111 is covered with a patterned steel plate 1, and an opening is left at the upper end of the first roller 6. A frame 8 is provided at the upper end of the patterned steel plate 1, and the two ends of the frame 8 are provided with second rollers 12. The second rollers 12 are vertically arranged, and the side of the second roller 12 is spaced from the side of the finished engineering tire 101.

[0024] Specifically, pit 111 is a prefabricated foundation pit. The drive mechanism is buried in pit 111 and covered with a patterned steel plate 1, which is flush with the ground. The highest point of the drive roller is flush with the ground, which facilitates the rolling of the tire. Several first rollers 6 are arranged at intervals in pit 111. Their upper surfaces are flush with the ground, and their upper parts are in direct tangential contact with the bottom of the finished engineering tire 101. With the help of the synchronous rotation driven by the drive mechanism, the tire is provided with stable circumferential motion power, replacing the laborious operation of manually rotating the tire.

[0025] Specifically, the outer surface of the first roller 6 is provided with parallel straight grooves, and several parallel straight grooves are arranged at intervals. The arrangement of the parallel straight grooves is conducive to driving the finished engineering tire 101 to rotate, and can also effectively prevent slippage.

[0026] Several second rollers 12 are spaced apart from the sides of the tire at both ends of the frame 8, and the second rollers 12 are rotatably connected to the frame 8. When the tire tilts, they will contact the second rollers 12, which can assist the tire in rotating, making it easier for the operator to straighten and adjust the tire. This ensures that the tire remains stable during the trimming and inspection process, providing a safe and stable working foundation for the operator.

[0027] like Figure 2 and Figure 3 As shown, the drive mechanism includes a motor 7, a motor reducer 103, a coupling 104, a sprocket 105, a chain 102, and bearings 106. The output end of the motor 7 is connected to one end of the motor reducer 103, and the other end of the motor reducer 103 is connected to one end of the coupling 104. The other end of the coupling 104 is connected to the first roller 6, and bearings 106 are installed at both ends of the first roller 6, with several bearings spaced apart. A sprocket 105 is fitted onto the output end of the coupling 104, and a chain 102 is installed on the sprocket 105. Several sprockets 105 are spaced apart at one end of the chain 102, and these sprockets 105 are connected to several first rollers 6.

[0028] Specifically, motor 7 transmits power to motor reducer 103, which in turn transmits it to coupling 104, thereby driving the first roller 6 to rotate. Simultaneously, sprocket 105 rotates, causing chain 102 to drive another sprocket 105 to rotate, which in turn causes the other first roller 6 to rotate. The two first rollers 6 work together to rotate the finished engineering tire 101, allowing workers to trim the rubber trimming and rough edges at different locations on the tire. At the same time, the bearings 106 at both ends of the first roller 6 further reduce rotational friction, ensuring smooth tire rotation and preventing shaking caused by jamming.

[0029] Several second rollers 12 are spaced apart at both ends of the frame 8, and the second rollers 12 are rotatably connected to the frame 8. Specifically, rotating bearings can be installed at both ends of the second rollers 12 to facilitate their rotation. Two second rollers 12 are installed at each end of the frame 8, with a gap between them. When the tire tilts, it will contact the second rollers 12, which can assist the tire in rotating, making it easier for the operator to straighten and adjust the tire.

[0030] LED strip lights 11 are installed on the top of the rack 8, with several LED strip lights 11 spaced apart; extended universal light heads 9 are installed at both ends of the front of the rack 8.

[0031] Specifically, several LED strip lights spaced at intervals on the top of the frame 8 form a uniform overhead main light source, whose illumination range covers the entire tire repair area. This clearly illuminates most of the rubber, burrs, and surface defects on the tire surface, providing basic lighting for operators and avoiding blind spots caused by dim ambient light. The extended omnidirectional light heads 9 at both ends of the front of the frame 8 are flexibly adjustable, allowing operators to adjust the light head orientation at any time according to the lighting needs of different tire locations, achieving precise supplemental lighting for specific areas.

[0032] By combining the LED strip lighting 11 and the extended omnidirectional light head 9, not only are the light and shadow on the tire surface eliminated, but the fine rubber burrs and rough edges distributed in various positions are also clearly highlighted, ensuring that the operator does not miss any during the trimming process, reducing the rework rate caused by missing burrs or incomplete inspection, and improving the quality and efficiency of tire repair.

[0033] A start / stop / emergency stop button box 10 is installed at the lower part of the extended universal lamp head 9, and the start / stop / emergency stop button box 10 is mounted on the frame 8. Specifically, the start / stop / emergency stop button box 10 is located at both ends of the frame 8 for easy and quick use in emergency situations to cut off power.

[0034] A warning tri-color light 13 is installed at the lower part of the LED strip light 11, and the warning tri-color light 13 is mounted on the frame 8. Specifically, the warning tri-color light 13 indicates the operating status of the equipment, whether it is idle, running, or malfunctioning, so that the staff can quickly understand the status of the equipment. The front two ends of the patterned steel plate 1 are provided with start foot pedals 4, and one end of the start foot pedal 4 is provided with a stop foot pedal 5; both the start foot pedal 4 and the stop foot pedal 5 are installed on the patterned steel plate 1.

[0035] Specifically, the start foot pedals 4 at both ends of the front of the patterned steel plate 1 and the stop foot pedal 5 at the end provide operators with a convenient foot control method. During tire repair, operators need to hold tools to handle tire burrs, and can control the equipment to start and stop by stepping on the pedals, without having to free their hands to operate the buttons, effectively freeing their hands and improving the continuity and efficiency of the burr removal action. At the same time, the start foot pedals 4 at both ends are adapted to the operating needs of different work positions.

[0036] A detection photoelectric sensor 3 is installed on one side of the frame 8. Specifically, the detection photoelectric sensor 3 on one side of the frame 8 can accurately sense the placement status of the finished engineering tire 101. When the tire is hoisted above the first roller group 6 and in place, the detection photoelectric sensor 3 can automatically identify and feed back a signal to the control system, preventing the equipment from running idle without a tire or starting when the tire is not placed stably, thus providing a preliminary safety guarantee for the operation of the equipment.

[0037] A distribution box 2 is installed at one end of the patterned steel plate 1. The distribution box 2 is electrically connected to the drive mechanism, start foot pedal 4, stop foot pedal 5, detection photoelectric sensor 3, extended universal lamp head 9, LED strip lighting 11, start / stop / emergency stop button box 10, and warning tri-color light 13. Specifically, the distribution box 2 realizes centralized linkage of all electrical components. It can accurately distribute power through the circuit and quickly cut off the power supply to relevant components when the detection photoelectric sensor 3 senses abnormalities or the emergency stop button is triggered, ensuring the stability of the electrical system throughout the tire repair process and providing basic support for the safe and efficient operation of the equipment.

[0038] Instructions for using the finished engineering tire repair device: The operator first checks whether the power supply to the distribution box 2 is connected, observes the status of the warning tri-color light 13, and confirms that the equipment is in an idle state. Then, the LED strip lighting is turned on, and the illumination angle of the extended universal lamp head 9 is adjusted according to the work requirements to ensure sufficient lighting in the tire repair area.

[0039] like Figure 4 As shown, a crane is used to lift the finished engineering tire 101 to be repaired from the X-ray machine station and place it on the ground. Then, the operator pushes the tire above the first roller group 6 on the patterned steel plate 1, ensuring that the bottom of the tire is in full contact with the first roller 6, while maintaining a certain distance between the tire and the second rollers 12 at both ends of the frame 8. At this time, the detection photoelectric sensor 3 on one side of the frame 8 senses that the tire is in place and sends a signal to the control system. The warning tri-color light 13 illuminates the corresponding indicator light, indicating that the equipment can be started and operated.

[0040] The operator begins trimming the rubber fray and rough edges. When the position needs to be adjusted after trimming an area, the operator steps on the start or jogs the foot pedal 4, and the drive mechanism starts running. The motor 7 drives all the first rollers 6 to rotate synchronously through the reducer, coupling 104, sprocket 105, and chain 102, thereby driving the tire to rotate smoothly around its own axis. After rotating to the required position, the operator steps on the stop foot pedal 5, and the operator uses the trimming tool to trim another area. With the help of the basic lighting of the LED strip light and the local supplementary lighting of the extended universal lamp head 9, the rubber fray and rough edges on the tire surface are trimmed.

[0041] In case of an emergency during tire repair, immediately press the start / stop emergency stop button box 10. The equipment will quickly cut off power, and the first roller 6 will stop rotating. The angle of the extended universal lamp head 9 can be adjusted at any time according to the trimming requirements of different parts of the tire to ensure no blind spots in concealed areas and avoid missing any rough edges. Once the tire trimming and inspection are complete, the equipment stops operating, and the warning tri-color light 13 switches to idle mode. Turn off the LED strip lighting and the extended universal lamp head 9, and the operator can then push the tire to roll it away from the workstation.

[0042] A movable stool with casters can be placed next to the finished engineering tire 101 tire repair device, which changes the standing operation to a sitting operation and reduces the labor intensity of employees.

[0043] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
