Abstract
Description
Technical Field
[0001] This utility model relates to a crown band straightening device. Background Technology
[0002] In the crown production and storage process, crowns are typically stored using a core-wound method. When crowns exhibit abnormalities, such as localized defects or tangled winding, the abnormal portion needs to be extracted from the core for processing. Currently, the industry standard practice is to place the core containing the abnormal crown on a simple spool and manually extract the crown, then wind it onto a winding reel. This manual method has several drawbacks: firstly, it is extremely labor-intensive for employees, and prolonged repetitive operations can easily lead to fatigue, affecting work efficiency and quality; secondly, it has low processing efficiency, failing to meet the demands of large-scale production and severely restricting production progress; thirdly, manual operation makes it difficult to ensure the uniformity and stability of crown transfer and winding processes, easily causing crown misalignment, wrinkles, and other problems, further affecting crown quality and subsequent use. Therefore, the development of an efficient and automated crown sorting device is urgently needed to solve the aforementioned problems in existing technologies. Utility Model Content

[0025] The present invention or its technical solution will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0026] In the description of this utility model, it should be noted that, unless otherwise specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0027] Please see Figure 1 and Figure 2 This utility model provides a crown band straightening device, which includes a guide mechanism 1, a transition mechanism 2 and a winding mechanism 3.
[0028] The guide mechanism 1 includes a first base 11 and a guide core 12 rotatably mounted on the first base 11. The guide core 12 is used to support the crown band core. The transition mechanism 2 is located downstream of the guide mechanism 1. The transition mechanism 2 includes a second base 21 and a guide rod cable guide 22 mounted thereon. The guide rod cable guide 22 is used to guide the crown band transmission path. The automatic reciprocating cable guide function of the guide rod cable guide 22 ensures that the crown band can be wound evenly, tightly and neatly layer by layer on the winding core 33, effectively avoiding the stacking, gaps and uneven edges common in manual winding.
[0029] The winding mechanism 3 is located downstream of the transition mechanism 2. The winding mechanism 3 includes a third base 31, a reduction motor 32 fixed to the third base 31, a winding core 33 driven by the reduction motor 32, and a first winding chuck 34 and a second winding chuck 35 symmetrically sleeved at both ends of the winding core 33. At least one of the first winding chuck 34 and the second winding chuck 35 is detachably mounted on the winding core 33. The portion of the winding core 33 located between the first winding chuck 34 and the second winding chuck 35 is fitted with a crown strip winding core 36.
[0030] The first base 11, the second base 21, and the third base 31 are at the same horizontal height. The guide mechanism 1, the transition mechanism 2, and the winding mechanism 3 are arranged sequentially along the crown belt transmission direction to ensure that the crown belt forms a continuous and flat support or guide surface along the transmission path. This arrangement effectively prevents sagging, friction, or sudden tension changes in the crown belt due to height differences during transmission, thereby avoiding wrinkles, damage, and misalignment, and ensuring the stability of transmission and winding.
[0031] Crown strips are typically narrow strip materials (such as the crown layer in a tire). In a preferred embodiment of this invention, the crown strip core 36 is composed of two symmetrically arranged conical drums 361 and 362. The first take-up chuck 34 and the second take-up chuck 35 are used to clamp and fix the crown strip core 36. The inclined structure of the conical drums provides axial force during winding, forcing the crown strip to slide naturally along the conical surface towards the root (larger diameter end), avoiding interlayer shift, edge loosening, or collapse during winding, ensuring a neat and tight roll. Furthermore, the conical structure, combined with a detachable chuck, allows the rolled crown strip to be easily slid out axially using the conical inclination after removing one chuck, avoiding the jamming problem of traditional straight-tube cores.
[0032] The detachable take-up chuck design makes loading and unloading the wound reel very simple and quick, further improving equipment utilization and operational convenience. In some embodiments of this invention, the first take-up chuck 34 or the second take-up chuck 35 is detachably connected to the take-up core 33 via a threaded connection or pin structure. In some examples, the chuck is fastened to the threaded section of the take-up core by screwing, with its inner end face tightly fitted to the large end face of the tapered drum.
[0033] The geared motor 32 includes a frequency converter and a reducer, and the speed adjustment range of its output shaft (i.e., the shaft that drives the winding core 33) is 5-50 rpm. The motor-driven winding speed is adjustable, and together with the free rotation of the guide mechanism 1 and the guidance of the transition mechanism 2, it helps to maintain a relatively stable transmission tension and reduce the phenomenon of uneven tension.
[0034] Optionally, the first base 11 is provided with a first bearing seat 13 and a second bearing seat 14, and the guide core 12 is provided in the first bearing seat 13 and the second bearing seat 14.
[0035] The bare rod cable guide 22 includes a support frame 23 fixedly mounted on a second base 21, a slide rail 24 mounted on the support frame 23, and a cable guide head 25 slidably mounted on the slide rail 24. The cable guide head 25 has at least one cable guide roller 251 for guiding the crown band. A drive mechanism 26 is mounted on the support frame 23 and drives the cable guide head 25 to reciprocate laterally along the slide rail 24. At least one reversing sensor 27 is fixedly mounted on the cable guide head 25. The support frame 23 has sensing trigger blocks 281 and 282 that cooperate with the reversing sensor 27. When the cable guide head 25 moves to the end of its travel, the sensing trigger blocks 281 and 282 trigger the corresponding reversing sensor 27, which sends a signal to control the drive mechanism 26 to reverse direction. The reversing sensor 27 sends a signal to control the drive mechanism 26 (such as a motor or cylinder) to reverse direction, achieving automatic reciprocating cable routing and ensuring that the crown band is wound evenly and neatly on the take-up core 33, avoiding stacking or gaps.
[0036] The two symmetrical tapered drums 361 and 362 are both truncated cones with their small end faces touching each other and their large end faces contacting the inner end faces of the first take-up chuck 34 and the second take-up chuck 35.
[0037] Optionally, the drive mechanism includes, but is not limited to, a lead screw and nut mechanism driven by a servo motor and a synchronous belt mechanism driven by a stepper motor.
[0038] In some embodiments, the tapered drums 361 and 362 are made of high-strength aluminum alloy or structural steel to ensure sufficient strength and durability, and to provide good tapered clamping effect to accommodate crown cores of different widths, ensuring stable clamping.
[0039] The specific working method of the device is as follows: the winding reel is placed on the conical drums 361 and 362, and the employee manually leads out the crown tape and winds it up to the take-up core 33 through the guide rod wire guide 22. After the guide is completed, it is automatically guided by the reduction motor 32. After the crown tape is unwound, the detachable take-up chuck is removed, and the sorted crown tape can be taken off.
