Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for gauze processing, and in particular to a gauze roll support clamp. Background Technology

[0002] Gauze, as a new type of material with properties such as moisture resistance, breathability, flexibility, and environmental friendliness, is widely used in various industries such as medical care, hygiene, agriculture, and packaging. In the production process of gauze, the finished product is usually rolled, stored, and transported in roll form. Its structure generally consists of gauze layers wound around a cylindrical core, forming a roll with a large diameter and heavy weight.

[0003] To transfer the gauze rolls, lifting equipment and clamps are required. Currently, the commonly used gauze roll lifting methods in the industry have the following technical drawbacks: 1. Traditionally, rope binding or simple chuck clamping is used. Uneven force on rope binding can easily cause the gauze roll to loosen, deform or even slip off; simple chuck only clamps the end of the core cylinder and cannot limit the radial displacement of the roll, making it easy to shake during hoisting and resulting in insufficient safety during high-altitude transportation. 2. The top and bottom ends of the gauze roll are exposed and soft gauze layers. Existing clamps lack a special end-face protection structure. During the transfer process, the end faces are prone to friction and collision with the clamps or other objects, resulting in fuzzing and damage at the edges, which affects product quality. Some clamps are in rigid contact with the core cylinder, which may also cause deformation of the core cylinder and damage the winding precision of the internal gauze layer. 3. Different specifications of gauze rolls require corresponding sizes of clamps. Most existing clamps are integrated structures, which cannot flexibly adjust the clamping range. Enterprises need to stock various specifications of clamps, which increases equipment investment costs and storage space occupation. Moreover, the connection method between the clamp and the core tube is fixed, making it difficult to adapt to core tubes with different inner diameters. 4. Existing clamps and booms are mostly fixed structures, and the lifting angle cannot be adjusted. When transferring in narrow spaces or special work positions, they are prone to interfering with surrounding equipment, which restricts operation. Moreover, the installation and disassembly of clamps are complicated, requiring multiple people to work together, resulting in low lifting efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, there is an urgent need for a lifting clamp that is structurally reasonable, stable, highly adaptable, can effectively protect the gauze rolls, and is flexible in operation, so as to solve the safety and quality problems in the gauze roll transfer process, improve work efficiency, and reduce enterprise production costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A gauze roll support clamp includes a protective frame, a hanger, and stop bars. The protective frame is disposed at the upper and lower end faces of the gauze roll, and the stop bars are connected between the protective frames. The gauze roll is fixed between the stop bars. A core cylinder is disposed at the axis of the gauze roll. The hanger and the core cylinder are connected by a clamp. A movable boom is disposed on the hanger, and the boom is connected to an external lifting system.

[0006] In a preferred embodiment, the protective frame includes an outer ring and an inner ring, the outer ring and the inner ring are coaxially arranged, the inner ring is sleeved on the outer wall of the core cylinder, a connecting rod connects the outer ring and the inner ring, and multiple connecting plates are arranged on the outer ring along the circumferential direction.

[0007] In a preferred embodiment, the two ends of the stop bar are perpendicular to the outer ring, and the stop bar and the connecting plate are respectively provided with threaded mounting holes. The connecting bolts are threadedly connected to the threaded mounting holes, and the two ends of the stop bar are locked and fixed.

[0008] In a preferred embodiment, the hanger includes two semi-circular clamping rings, which are fitted onto the outer wall of the core cylinder. Each clamping ring has an ear plate at its end, and a fastening bolt is threaded into a threaded hole on the ear plate to lock and fix both ends of the clamping ring to achieve tight clamping and fixing of the core cylinder. The clamping rings are slidably connected to the boom.

[0009] In a preferred embodiment, an annular groove is provided on the clamp ring, and an annular slide rail is correspondingly provided on the side of the boom. The slide rail is engaged in the groove, so that the boom slides in a limited manner along the circumference of the clamp ring.

[0010] In a preferred embodiment, multiple threaded limiting holes are equidistantly provided on both sides of the slide rail, and a limiting plate is provided on the side of the boom. The limiting plate is located on both sides of the slide rail and has corresponding threaded limiting holes. The limiting bolts are threadedly connected to the threaded limiting holes to lock and fix the position of the boom.

[0011] In a preferred embodiment, a lifting ring is provided at the end of the boom, and the lifting ring is connected to an external lifting system.

[0012] A gauze roll support clamp, the device having the following beneficial effects: 1. The protective frames on the upper and lower ends of the gauze roll and multiple baffles form a closed-loop limit, effectively restricting radial displacement and preventing swaying during hoisting; the hanger adopts a clamp-type structure to be tightly connected to the core cylinder, which has higher connection strength and more uniform force distribution compared with the traditional method, eliminating the risk of loosening, deformation or slippage of the roll material, and greatly improving the safety of high-altitude transportation. 2. The protective frame structure provides comprehensive protection for the exposed end face of the gauze roll, preventing edge fraying and damage caused by friction and collision; the inner ring is flexibly fitted with the core tube, and the clamp ring can adjust the locking force to prevent rigid deformation of the core tube, ensuring the winding accuracy of the gauze layer and ensuring that product quality is not affected by hoisting. 3. The stop bar and the protective frame are detachably connected, and the number and spacing of the stop bars can be adjusted according to the length of the gauze roll; the clamp rings can be adjusted by fastening bolts to adapt to different inner diameter core cylinders, eliminating the need for special clamps, reducing equipment investment and storage space, and improving the clamp reuse rate; 4. The lifting angle of the boom can be adjusted along the circumference of the clamp ring, which is suitable for transportation in narrow spaces or special work positions and avoids interference with surrounding equipment; the installation and disassembly of the clamps only require tightening or loosening of bolts, which can be operated by a single person, simplifying the operation process and improving the efficiency of lifting and transportation. 5. The clamping force of the clamping ring is adjusted by tightening the bolts, and the position of the boom is fixed by the limiting bolts, forming an adjustable locking mechanism. This mechanism can provide sufficient clamping force to ensure stability while preventing the roll material from being squeezed and deformed. It balances the dual needs of stable clamping and roll material protection and is suitable for gauze rolls of different weights and materials. Attached Figure Description
