Description

Technical Field

[0001] The utility model relates to the technical field of tire processing, in particular to a green tire puncturing machine. Background Art

[0002] Before the tire is vulcanized and formed, the green tire embryo must be evenly punctured, which is conducive to the discharge of the gas generated during the vulcanization process, so that no pores remain inside the tire after forming, ensuring the quality of the tire and the safety of use. There are many green tire puncturing machines on the market. These puncturing machines can automatically move the green tire so that the entire circumference of the green tire can be punctured. However, in order to facilitate loading and unloading, most puncturing machines do not have a limiting mechanism. After the green tire is placed on the tire hanging component, the axial direction of the green tire is not restricted. Therefore, when the green tire rotates, it will shift and it is easy to slide off the puncturing machine during puncture. In this way, the staff needs to restart the puncture process, which is not only time-consuming but also increases the burden on the staff.

[0003] The technical content disclosed in the Chinese patent document (Announcement No.: CN208133115U, Patent Name: A tire embryo automatic puncturing machine) is: base 1, frame 2, puncturing assembly and tire embryo hanging roller 8, frame 2 is fixed on base 1, frame 2 and base 1 form an inverted T shape, puncturing assembly includes needle rotating motor 3, gear box 4, drill chuck 5 and needle 6, needle rotating motor 3 drives needle 6 to rotate through gear box 4 and drill chuck 5 in turn. Needle 6 is a double-row needle. When needle rotating motor 3 runs, needle 6 rotates, and rotating needle 6 has higher puncturing efficiency, and rotating needle 6 can reduce the friction between needle 6 and tire embryo, prevent tire embryo from moving up with needle 6, which is beneficial to production continuity and product stability. Using double-row needles 6 to puncture at the same time can improve puncturing efficiency, and is beneficial to improving the uniformity of puncturing and improving tire embryo quality.

[0004] It can be seen from the above implementation scheme that the piercing machine does not have a limiting mechanism to limit the axial direction of the green tire. The axial direction of the green tire is mainly fixed by the friction between the green tire and the tire embryo roller. Therefore, it is easy for the green tire to fall off the piercing machine during processing, resulting in processing instability and increasing the burden on the staff. Utility Model Content

[0005] The utility model overcomes the shortcomings of the prior art and provides a limiting mechanism to position the axial direction of the green tire, thereby ensuring that the green tire will not fall off the puncturing machine when it is rotated for puncturing.

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] like Figures 1 to 6 As shown, a green tire puncturing machine comprises a power assembly 2, the power assembly 2 is connected to a puncturing mechanism 3 and a progressive rotating mechanism 4, the progressive rotating mechanism 4 is located at the side of the puncturing mechanism 3, and limiting mechanisms 6 are arranged on the left and right sides of the puncturing mechanism 3, and a supporting rotating mechanism 5 is arranged below the progressive rotating mechanism 4. The supporting rotating mechanism 5 can be raised and lowered relative to the progressive rotating mechanism 4. When the supporting rotating mechanism 5 is at the lowest position, it is lower than the lowermost end of the limiting mechanism 6. When the supporting rotating mechanism 5 is raised, it is inserted between the two limiting mechanisms 6. When the supporting rotating mechanism 5 is at the lowest position, the green tire can be hung on the supporting rotating mechanism 5, and at this time, the axial direction of the green tire is not affected by the limiting mechanism 6. The restriction also allows the staff to directly hang the green tire on the supporting rotating mechanism 5 without adding the action of the opening and closing limit mechanism 6, and then the supporting rotating mechanism 5 rises until the upper surface of the green tire abuts against the progressive rotating mechanism 4, so that the progressive rotating mechanism 4 can drive the green tire to rotate intermittently, thereby realizing the intermittent puncturing of the green tire by the puncturing mechanism 3. After the supporting rotating mechanism 5 rises, the supporting rotating mechanism 5 is inserted between the two limit mechanisms 6, and the green tire is also inserted between the two limit adjustment seats 602 of the limit mechanism 6, so that the axial direction of the green tire is limited by the limit adjustment seat 602, thereby ensuring that the green tire will not fall off the puncturing machine when rotating for puncture.

[0029] The power assembly 2 is installed in the frame 1. The upper end of the frame 1 is provided with a driving seat bearing 101. Sliding sockets 102 are provided on both sides of the frame 1. The power assembly 2 includes a motor 201. The motor 201 is connected to the chain 202. The chain 202 is connected to the transmission shaft 203. The transmission shaft 203 is connected to the driving seat bearing 101. The transmission shaft 203 is connected to the piercing mechanism 3 and the progressive rotation mechanism 4. Therefore, when the motor 201 drives the transmission shaft 203 to rotate, it can simultaneously drive the needle 305 of the piercing mechanism 3 to move up and down to continue piercing the green tire, and can also drive the progressive toggle shaft 406 of the progressive rotation mechanism 4 to toggle the green tire in a circumferential direction. When the transmission shaft 203 rotates one circle, the needle 305 of the piercing mechanism 3 is driven to move up and down to continue piercing the green tire. 305 completes an up and down movement, and the progressive toggle shaft 406 completes a toggle. The coordination of the actions between the two is that the connection between the progressive connecting seat 404 and the progressive connecting rod 403 is just pushed to the lowest position. At this time, the progressive connecting seat 404 is about to be pulled upward, and the stay time in the conversion process is the longest. At this time, the needle 305 just descends to pierce the raw tire. As the progressive connecting seat 404 is pulled upward, the progressive toggle shaft 406 drives the raw tire to rotate, and the needle 305 moves upward to pull out the upper surface of the raw tire. This cycle is repeated, and the progressive toggle shaft 406 drives the raw tire to rotate a certain distance, and the needle 305 pierces a row of needle holes in the raw tire, so that the raw tire is evenly pierced in the circumferential direction.

[0030] The piercing mechanism 3 includes a piercing drive cam 301, which is connected to a lifting link 302. The connection point between the lifting link 302 and the piercing drive cam 301 is at a position offset from the center of the piercing drive cam 301 by a certain distance. Therefore, when the piercing drive cam 301 rotates, the lifting link 302 is driven to move up and down. The lifting link 302 is connected to a sliding rod 303, and the sliding rod 303 is connected to a puncture needle seat 304. Therefore, the lifting link 302 drives the sliding rod 303 to slide and plug with the sliding socket 102, and the lower end of the puncture needle seat 304 is connected to the puncture needle 305, thereby realizing the up and down movement of the puncture needle 305.

[0031] The progressive rotation mechanism 4 includes a progressive driving cam 401, which is connected to the transmission shaft 203. The connection between the progressive driving cam 401 and the transmission shaft 203 deviates from the center of the circle of the progressive driving cam 401 by a certain distance. The progressive driving cam 401 is rotatably connected to a progressive passive wheel 402. Therefore, when the progressive driving cam 401 rotates, the progressive passive wheel 402 will drive the upward and downward deviation. The lower end of the progressive passive wheel 402 is connected to the progressive connecting rod 403, so the upper end of the progressive connecting rod 403 is also pulled up and down, and the progressive connecting rod The lower end of 403 is hinged to the progressive connecting seat 404, so the progressive connecting rod 403 pulls one end of the progressive connecting seat 404 to swing up and down, and the progressive connecting seat 404 is connected to the progressive transmission shaft 405, so the progressive connecting seat 404 drives the progressive transmission shaft 405 to swing within a certain angle, and the two ends of the progressive transmission shaft 405 are connected to the progressive shifting shaft 406, and the lower end of the progressive shifting shaft 406 is connected to the upper surface of the green tire, and the lower surface of the green tire is supported by the raised supporting rotating mechanism 5, so the green tire is also driven by the progressive shifting shaft 406 to perform circumferential rotation in stages.

[0032] The support rotation mechanism 5 includes a support lifting groove 501, which is located on the inner side of the frame 1. A support lifting cylinder 502 is provided at the lower end of the support lifting groove 501. The support lifting cylinder 502 is connected to the frame 1. The output end of the support lifting cylinder 502 is connected to the support seat 503. The support seat 503 is slidably plugged into the support lifting groove 501. The support seat 503 includes a lifting sliding block 5031. The lifting sliding block 5031 is connected to the piercing pad 5032. The piercing pad 5032 is made of a soft and pierceable material, which can be sponge, cloth or rubber, etc.

[0033] Lateral support shafts 504 are provided on both sides of the piercing cushion 5032, and the lateral support shafts 504 are rotatably connected to the support seat 503. When the green tire is hung on the supporting rotation mechanism 5, the two points at which the green tire contacts the supporting rotation mechanism 5 are the lateral support shafts 504. Therefore, when the progressive driving shaft 406 drives the green tire to rotate, the lateral support shafts 504 below the green tire also rotate, so that the green tire can rotate smoothly.

[0034] The limiting mechanism 6 includes a limiting adjustment base rod 601, on which a limiting adjustment seat 602 is slidably inserted. In this embodiment, two limiting adjustment seats 602 are slidably inserted on the limiting adjustment base rod 601, which are respectively used to limit the two sides of the axial direction of the green tire. The limiting adjustment seat 602 includes a limiting sliding block 6021 and a limiting swing rod 6022 fixed together. The limiting swing rod 6022 can limit the green tire in a larger range and at a position farther from the limiting adjustment base rod 601 relative to the limiting sliding block 6021. Therefore, the limiting adjustment base rod 601 does not need to be installed very close to the supporting rotation mechanism 5, so that the distance between the mechanisms is farther and less likely to collide. The limiting sliding block 6021 is threadedly connected with a positioning bolt 603, and one end of the positioning bolt 603 is against the limiting adjustment base rod 601. According to the different widths of the green tire, the positioning bolt 603 can be loosened to adjust the position of the limiting adjustment seat 602, which is very convenient.
