Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cord production, and particularly relates to a cord clamping device capable of preventing cord falling. BACKGROUND

[0002] In the process flow of cord stranding production, the quality and stability are directly related to the performance and safety of tires. During the processing of the cord, the cord needs to pass through multiple processes, and orderly clamping and guiding the cord to the take-up position is a key step to ensure the smooth progress of subsequent production. The traditional cord processing method often relies on simple mechanical structures or manual operation to maintain the tension and position of the cord, but this approach has many shortcomings.

[0003] Specifically, in the absence of an effective clamping device, the cord is prone to accidental falling from the twist limiting wheel and the guide wheels of the take-up due to factors such as vibration, friction, or uneven tension during transmission. This falling cord phenomenon not only directly interferes with the normal twisting of the cord, but also can cause the cord to form coils of different sizes during the subsequent twisting process, i.e., the so-called "size circle" phenomenon. This irregular arrangement of the cord can seriously affect the overall strength and uniformity of the cord, thereby creating a safety hazard in tire manufacturing. In particular, when the tire is subjected to extreme conditions such as high-speed rotation or heavy load, the instability of the tire structure caused by poor cord twisting or wave phenomenon will greatly increase the risk of tire blowout, posing a serious threat to road safety.

[0004] In summary, there is a certain market demand for designing a clamping device that can automatically adapt to changes in production conditions and effectively clamp the cord to prevent it from falling when necessary. SUMMARY

[0007] Further, the telescopic mechanism is a piston cylinder, and the piston end of the piston cylinder is connected to the push rod.

[0008] Further, the adjustment plate is provided with a plurality of guide rails, and the fixed base is provided with a guide pin matched with the guide rails.

[0009] Furthermore, the fixed clamp is provided with several guide shafts parallel to the push rod, and the vertical plate is provided with bushings adapted to the guide shafts.

[0010] Furthermore, the adjusting locking part is an adjusting bolt, the fixed base is provided with a screw hole for screwing the adjusting bolt, the sliding adjusting plate is provided with a through hole groove that cooperates with the adjusting bolt, and a shim is provided between the adjusting bolt and the sliding adjusting plate.

[0018] To better understand this utility model, the following is in conjunction with... Figs. 1-3 The embodiments of this utility model will be explained in detail below.

[0019] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all relative to the direction of the text. Fig. 1 The directions are based on "front, back, left, right, up, down".

[0020] The utility model discloses a kind of anti-off wire's cord clamping devices, including one upper and lower parallel and stable fixed seat 1, this fixed seat 1 as the basis of entire clamping device, ensure its stability. Vertical vertical plate 2 is provided with welding or integrated molding on fixed seat 1, one "L" shape sliding adjustment plate 3 in vertical plate 2 side is slidably arranged on fixed seat 1. The design of this sliding adjustment plate 3 allows user to adjust the width of clamping according to the diameter of cord or production demand. In order to realize this adjusting function, adjusting locking portion is provided between sliding adjustment plate 3 and fixed seat 1, specifically, adjusting locking portion is adjusting bolt 12, screw hole of adjusting bolt 12 is provided on fixed seat 1, through-hole sliding groove 13 matched with adjusting bolt 12 is provided on sliding adjustment plate 3, gasket 14 is provided between adjusting bolt 12 and sliding adjustment plate 3, to ensure the stability after adjustment.

[0021] The inside of sliding adjustment plate 3 is mounted with a fixed clamping plate 4, and the fixed clamping plate 4 and the sliding adjustment plate 3 jointly constitute one side of the cord clamping. A horizontal push rod 5 is provided on the vertical plate 2, and the inner end of the push rod 5 is connected with a movable clamping plate 6. The movable clamping plate 6 is arranged opposite to the fixed clamping plate 4 and is used for clamping the other side of the cord. In order to realize the telescopic action of the movable clamping plate 6, a telescopic mechanism 7 is provided on the vertical plate 2 to drive the push rod 5 to telescope. Specifically, the telescopic mechanism 7 is a piston cylinder, and the piston end of the piston cylinder is connected with the push rod 5. The push rod 5 is driven to telescope by the telescopic action of the piston cylinder.

[0022] In order to ensure that the inner clamping surfaces of the fixed clamping plate 4 and the movable clamping plate 6 can bear force uniformly and avoid the occurrence of a clamping angle due to angle deviation when the sliding adjustment plate 3 is adjusted, considering the stability of the fixed clamping plate 4 during clamping, a plurality of guide rails 8 are provided on the sliding adjustment plate 3, and a plurality of guide pins 9 matched with the guide rails 8 are provided on the fixed seat 1. In addition, a plurality of guide shafts 10 parallel to the push rod 5 are provided on the fixed clamping plate 4, and a plurality of shaft sleeves 11 matched with the guide shafts 10 are provided on the vertical plate 2. At the same time, the guide shafts 10 and the shaft sleeves 11 can also share the radial burden of the piston cylinder caused by the push rod 5 during clamping, thereby increasing the service life of the piston cylinder.

[0023] In addition, in order to facilitate the user to adjust the position of the sliding adjustment plate 3, a spacing scale line 15 matched with the sliding adjustment plate 3 is further provided on the fixed seat 1, and the user can intuitively adjust the clamping width according to the scale line.

[0024] In material selection, the fixed clamping plate 4 and the movable clamping plate 6 adopt the round nylon plate, and the coaxial arrangement. The nylon plate has good wear resistance and toughness, which can effectively protect the cord from being injured, and at the same time, the circular design also helps to reduce the pressure concentration on the cord in the clamping process. In addition, considering the durability of the nylon plate, the fixed clamping plate 4 and the movable clamping plate 6 are designed to be detachable, which are used as replaceable spare parts. Specifically, the fixed clamping plate 4 and the movable clamping plate 6 are provided with counterbores, and are detachably connected with the push rod 5 and the sliding adjusting plate 3 through bolt connection.

[0026] Firstly, the clamping device is installed at the rear of the BBP wheel, and the position of the sliding adjusting plate 3 is adjusted through the adjusting bolt 12 according to the diameter of the cord or production requirements. Then, the cord is placed between the fixed clamping plate 4 and the movable clamping plate 6, and the cord is as far as possible to pass through the center of the fixed clamping plate 4 and the movable clamping plate 6. Next, when the cord alarm stops or the spool is full, the piston cylinder starts to move the push rod 5 and the movable clamping plate 6 to the fixed clamping plate 4, and tightly clamps the cord. Finally, when the cord needs to be released, the piston cylinder moves reversely, the movable clamping plate 6 returns to the original position, and the cord can pass freely.
