Description

Technical Field

[0001] The utility model belongs to the technical field of tire marking, and in particular relates to a tire chalk marking device. Background Art

[0002] The production of treads and sidewalls is crucial in the tire manufacturing industry, but this process is affected by numerous factors, resulting in variations in product weight, width, and end-face shape. To ensure product quality, inspection equipment is essential throughout the production process. When inspection equipment detects an anomaly in a product, it outputs an abnormality signal, which controls identification equipment to flag the issue, allowing operators in the next process to identify and make appropriate adjustments.

[0003] Currently, different marking equipment is used for different production stages. For cut products, inkjet printers are generally used for marking. However, inkjet printers are expensive, with high maintenance costs and subsequent costs such as consumables.

[0042] See attached Figures 1 to 6 , a schematic embodiment of the tire chalk marking device proposed in the present invention is given, and the tire chalk marking device includes a bracket unit 1, a first movable unit 2, a second movable unit 3 and a marking unit 4.

[0043] The support unit 1 is provided with a platform 7 for supporting tires. Specifically, the supported tires include finished tires and semi-finished tires, such as treads and sidewalls. A first movable unit 2 is mounted on the support unit 1. The movable end of the first movable unit 2 can move left and right along the support unit 1. A second movable unit 3 is mounted on the movable end of the first movable unit 2 to follow its movement. The movable end of the second movable unit 3 can be raised or lowered to move away from or closer to the first movable unit 2.

[0044] Marking unit 4 comprises a cylindrical body 41, a friction wheel 42, a pressure rod 43, and a first spring 44. Cylindrical body 41 is connected to the movable end of second movable unit 3, allowing marking unit 4 to follow the movement of the movable end of second movable unit 3. With the cooperation of first movable unit 2 and second movable unit 3, marking unit 4 can freely switch positions within the working area, thus adapting to different tire specifications.

[0045] The circular tube 41 is used to store chalk 8. The friction wheel 42 is provided at the end of the circular tube 41. The pressure rod 43 is inserted into the circular tube 41, and the pressure rod 43 abuts against the chalk 8. The first spring 44 is provided in the circular tube 41, and the first spring 44 abuts against the pressure rod 43 to keep the chalk 8 in abutment with the friction wheel 42. The surface of the friction wheel 42 is rough. During the rotation of the friction wheel 42, the chalk 8 can cover the surface of the friction wheel 42. The chalk powder on the surface of the friction wheel 42 is drawn on the surface of the tire product through the friction wheel 42. As the chalk 8 is consumed, the length of the chalk 8 becomes shorter and shorter. Due to the setting of the first spring 44, the pressure rod 43 always abuts against the chalk 8, thereby pressing the chalk 8 to maintain abutment with the friction wheel 42, ensuring the smooth progress of the marking work.

[0046] The bracket unit 1 includes a first rod 11, a second rod 12, and a third rod 13. Two first rods 11 are provided, arranged parallel to each other. Two second rods 12 are provided, each perpendicular to each of the first rods 11. The third rod 13 is located at the ends of the second rods 12 away from the first rod 11. The first, second, and third rods 11, 12, and 13 together form the main frame of the tire chalk marking device. The materials of the first, second, and third rods 11, 12, and 13 can be selected as needed to ensure sufficient stability of the bracket unit 1.

[0047] The platform 7 is arranged between the two first rods 11, and the platform 7 includes a plurality of rollers 71 arranged in parallel. When the tire is placed on the platform 7 composed of the plurality of rollers 71, the movement of the tire becomes very easy. Only a small external force is required for the tire to roll on the platform 7. The rollers 71 greatly reduce friction through rolling contact and can effectively protect the tread rubber of the tire. In addition, since the tire can move flexibly on the platform 7 composed of the rollers 71, the staff can easily rotate the tire to the appropriate position when operating the tire. The platform 7 will distribute the pressure to the plurality of rollers 71, so that each roller 71 is subjected to relatively small pressure. When a roller 71 is damaged, it is easy to replace without affecting the use of the entire platform 7, thereby extending the service life of the platform 7 and reducing the maintenance cost of the platform 7.

[0048] The first movable unit 2 includes a ball screw 21, a slider 22, and a hand wheel 23. The ball screw 21 is provided on the third rod 13. The slider 22 is the movable end of the first movable unit 2. The slider 22 is provided on the ball screw 21. The hand wheel 23 is connected to the ball screw 21. The hand wheel 23 is used to drive the ball screw 21 to rotate so that the slider 22 moves along the ball screw 21. Specifically, the operator realizes the left and right lateral movement of the slider 22 by operating the hand wheel 23. The second movable unit 3 includes a cylinder 31 and a mounting plate assembly 32. The cylinder 31 is fixed on the slider 22. The piston shaft of the cylinder 31 is connected to the mounting plate assembly 32. The mounting plate assembly 32 is the movable end of the second movable unit 3.

[0049] The tire chalk marking device also includes a control unit 5, which is arranged on the bracket unit 1 and is electrically connected to the second movable unit 3. The operator can control the position of the line drawing by the hand-cranked wheel 23. When the control unit 5 receives the tire product line drawing signal, it controls the piston shaft of the cylinder 31 to extend, and the marking unit 4 then descends, and the line marking work begins. After the line marking work is completed, the control unit 5 controls the piston shaft of the cylinder 31 to retract, and the marking unit 4 then rises. The control unit 5 can manually control the lifting and lowering of the cylinder 31, whether the line marking is enabled, and other functions. The operator can manually operate the control unit 5 to make the tire chalk marking device work, or can turn on or off the operation of the tire chalk marking device by using the button on the control unit 5.

[0050] The mounting plate assembly 32 includes a first mounting plate 321, a second mounting plate 322 and a second spring 323. The first mounting plate 321 is connected to the piston shaft of the cylinder 31, the second mounting plate 322 is connected to the circular tube body 41 of the marking unit 4, and the second spring 323 connects the first mounting plate 321 and the second mounting plate 322 to keep the marking unit 4 in contact with the tire, ensuring the smooth progress of the marking work and ensuring that the chalk marking is clear.

[0051] The setting of the second movable unit 3 enables the tire chalk marking device to be suitable for products of different thicknesses. It cooperates with the first movable unit 2 to move the marking unit 4 to the product surface. The setting of the second spring 323 can ensure that the marking unit 4 is always in close contact with the product surface. Through the movement of the product itself, the chalk mark is drawn on the product surface without causing deformation of the product surface.

[0052] To ensure that workers can promptly replace chalk 8 when it is nearly depleted, the tire chalk marking device in this embodiment further includes an alarm unit 6, which is connected to the control unit 5. Alarm unit 6 is configured to sound an alarm when chalk 8 has reached a set length, providing an audible and visual alarm to remind workers to promptly replace the chalk, ensuring continuous and efficient marking. Specifically, alarm unit 6 includes a sensor 61, which is mounted on the cylindrical body 41 and detects the contact between the end of the pressure rod 43 and the chalk 8, and an audible and visual alarm light 62, which is mounted on the bracket unit 1.

[0053] As the chalk 8 is consumed, the position of the pressure rod 43 is continuously lowered. When the chalk 8 is consumed to a certain extent, the pressure rod 43 can trigger the sensor 61, thereby emitting an audible and visual alarm. Specifically, in order to generate an alarm when the chalk 8 is consumed to a set length, the sensor 61 can be fixed at a set position on the cylindrical body 41 according to specific needs.

[0054] In order to facilitate the replacement of the chalk 8, the marking unit 4 further includes a nut 45, which is provided at the end of the cylindrical body 41 where the pressure rod 43 is inserted. When the chalk 8 needs to be replaced, it is only necessary to open the nut 45, take out the pressure rod 43, put the chalk 8 into the cylindrical body 41, and then put the pressure rod 43 back and tighten the nut 45.

[0055] In the above-described exemplary embodiment, the tire chalk marking device comprises a bracket unit, a first movable unit, a second movable unit, and a marking unit. This device features a simple structure, requires minimal maintenance, and utilizes inexpensive consumables. The chalk markings are clear and prevent them from falling off during product transport. Furthermore, the marking unit's clever structural design eliminates issues such as breakage caused by the soft texture of the chalk. Furthermore, the device features a chalk length detection function. When the chalk is nearly depleted, an alarm automatically alerts the operator to replace the chalk. This ensures high tire marking efficiency.

[0056] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0057] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
