Technical Field
[0001] This utility model relates to the field of steel strip technology, specifically to a clip for connecting the two ends of a steel strip. Background Technology
[0002] Steel strip, as an important metallic material, is widely used in industrial production and daily life. It typically refers to steel products with relatively thin thickness and moderate width, generally between 0.1 mm and 3 mm in thickness, and ranging from a few millimeters to several meters in width. The manufacturing process of steel strip generally includes rolling, cutting, and annealing steps, which ensure that the steel strip has good mechanical properties and dimensional accuracy. There are many types of steel strip, which can be divided into various categories according to their material and application, such as low-carbon steel strip, high-carbon steel strip, stainless steel strip, and alloy steel strip. Different types of steel strip have different characteristics and application areas. For example, low-carbon steel strip, due to its good plasticity and weldability, is often used in the manufacture of metal packaging and building materials; while stainless steel strip, due to its excellent corrosion resistance, is widely used in food processing, medical devices, and other fields.
[0003] Currently, steel strip clamps are generally used manually to connect and tighten steel strips. However, this manual operation requires operators to install and tighten the clamps themselves, increasing labor costs for large-scale production or applications requiring frequent operation. Furthermore, prolonged repetitive operation can lead to operator fatigue, increasing errors and safety hazards. Therefore, this solution does not meet current needs. To address this, we propose a new clamp for connecting the two ends of a steel strip. Utility Model Content

It features a first gear ring that rotates while the engaging teeth and engaging groove slide and engage, preventing reverse rotation. This solves the problem mentioned in the background section where manually operated steel strip clamps require manual installation and tightening, increasing labor costs for large-scale production or frequent operation. Furthermore, prolonged repetitive operation can lead to operator fatigue, increasing errors and safety hazards.

[0009] As an optional solution for connecting the two ends of a steel strip according to the present invention, a spring is connected between the engaging teeth and the groove, and the transmission assembly further includes a first gear ring sleeved on the outside of the rotating ring. The inner wall of the first gear ring is provided with an engaging groove, and the engaging teeth are slidably engaged with the engaging groove.
[0010] As an optional solution for connecting the two ends of a steel strip according to the present invention, wherein: the ends of several engagement teeth are respectively connected to pull ropes, and the ends of the pull ropes are connected to pull rings.
[0011] As an optional solution for connecting the two ends of a steel strip according to the present invention, a second gear is sleeved on the outer side of the second rotating shaft, and the first gear meshes with the second gear for transmission.

[0013] This utility model has the following beneficial effects:
[0014] 1. This clamp for connecting the two ends of a steel strip utilizes a transmission assembly. A servo motor drives the connecting cylinder to rotate, simultaneously rotating the first gear ring. The first gear ring meshes with the second gear, driving the second rotating shaft. Two clamping blocks move threadedly on the second rotating shaft, clamping the steel strip. Using a servo motor and gear transmission system, fully automated clamping operation is achieved without manual intervention. In large-scale production and frequent operation scenarios, this significantly reduces labor costs and avoids operator fatigue and related errors and safety hazards caused by prolonged operation. It solves the problem of manually installed and tightened steel strip clamps requiring manual installation, which increases labor costs in large-scale production or frequent operation scenarios. Furthermore, prolonged repetitive operation can lead to operator fatigue, increasing errors and safety hazards.
[0015] 2. The clamp used to connect the two ends of the steel strip has a locking tooth setting. When the servo motor stops or is powered off, it may reverse due to the reaction force of the load, which will cause the transmission component to move in the opposite direction and the clamping block to loosen. By engaging the locking tooth and locking groove, when the reverse occurs, the locking tooth and locking groove slide and engage at the same time as the first gear ring rotates, thus preventing the reverse. The bellows plays a protective role. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1 aims to address the issue of manually operated steel strap clamps requiring manual installation and tightening, which increases labor costs in large-scale production or frequent operation scenarios. Prolonged repetitive operation can also lead to operator fatigue, increasing errors and safety hazards. Please refer to [link to relevant documentation]. Figure 1-6 A clamp for connecting the two ends of a steel strip includes a mounting plate 110 and a mounting block 120. The mounting block 120 is mounted on the side of the mounting plate 110. The side of the mounting block 120 has a mounting cavity 130. A transmission assembly 140 is disposed inside the mounting cavity 130. A clamping device 160 is mounted on the side of the mounting block 120. The transmission assembly 140 and the clamping device 160 are used in conjunction.
[0025] The mounting plate 110 has several bolt slots 111 on its side. The mounting block 120 is connected to a servo motor 131 on its side. The output shaft of the servo motor 131 passes through the side of the mounting block 120. The end of the output shaft of the servo motor 131 is connected to a connecting cylinder 132. The inner wall of the mounting cavity 130 is fitted with a first rotating shaft 133 and a second rotating shaft 134. The transmission assembly 140 includes a rotating ring 141 sleeved on the outside of the first rotating shaft 133. The rotating ring 141 has several slots 142 on its side. The rotating shaft 143 is connected inside the slots 142. The rotating shaft 143 is connected to a locking tooth 144 on its side. The second rotating shaft 134 is a threaded rod and is threadedly connected to the inner wall of the mounting cavity 130.
[0026] In this embodiment: Through the transmission component 140, the servo motor 131 starts, driving the connecting cylinder 132 to rotate, simultaneously driving the first gear ring 150 to rotate. The first gear ring 150 meshes with the second gear 154, driving the second rotating shaft 134 to rotate. The two clamping blocks 161 move threadedly on the second rotating shaft 134, clamping the steel strip. Using the servo motor 131 and gear transmission system, fully automated clamping operation can be achieved without manual intervention. In large-scale production and frequent operation scenarios, this significantly reduces labor costs and avoids operator fatigue and the resulting errors and safety hazards caused by prolonged operation. It solves the problem that manually operated steel strip clamps require operators to install and tighten them, which increases labor costs in large-scale production or frequent operation scenarios. Furthermore, prolonged repetitive operation can lead to operator fatigue, increasing errors and safety hazards.
[0027] Example 2 aims to address the problem that the servo motor 131 may reverse due to the reaction force of the load when it stops or is powered off, thus causing the transmission component 140 to move in the opposite direction. This example is an improvement on Example 1. For details, please refer to Example 1. Figure 1-6 A spring 145 is connected between the engaging tooth 144 and the slot 142. The transmission assembly 140 also includes a first gear ring 150 sleeved on the outside of the rotating ring 141. The inner wall of the first gear ring 150 is provided with an engaging groove 151, and the engaging tooth 144 and the engaging groove 151 are slidably engaged.
[0028] A number of engaging teeth 144 are connected to pull ropes 152 at their ends, and pull rings 153 are connected to the ends of the pull ropes 152. A second gear 154 is sleeved on the outside of the second rotating shaft 134. The first gear and the second gear 154 mesh and drive each other. A slide rod 155 is slidably connected inside the mounting cavity 130. The clamping device 160 includes a clamping block 161 and a bellows 162. The clamping block 161 is connected to the two ends of the second rotating shaft 134 and the slide rod 155 respectively. There are two clamping blocks 161. The bellows 162 is connected between the two clamping blocks 161. A through groove 200 is opened on the side of the mounting block 120. The pull rope 152 passes through the side of the through groove 200.
[0029] In this embodiment: With the setting of the engaging tooth 144, when the servo motor 131 stops or is powered off, it may reverse due to the reaction force of the load, which will cause the transmission component 140 to move in the opposite direction, causing the clamping block 161 to loosen. Through the engagement of the engaging tooth 144 and the engaging groove 151, when the reverse occurs, the engaging tooth 144 and the engaging groove 151 slide and engage at the same time as the first gear ring 150 rotates, thus preventing the reverse. The bellows 162 plays a protective role.
