Description

Technical Field

[0001] This utility model relates to the field of protective technology in thin film production, and in particular to a protective structure for thin film production equipment. Background Technology

[0002] In modern film production workshops, automated equipment operates at high speeds, presenting numerous moving parts, high-temperature areas, and electrical hazards. To ensure the safety of operators and prevent accidental entry into hazardous areas, physical safety barriers are typically installed around the equipment. This protective structure is a fundamental and mandatory facility constituting the entire production line safety system, meeting OSHA (Occupational Safety and Health Administration) regulations and related standards, and is crucial for preventing workplace accidents.

[0003] Currently, traditional safety barriers widely used in factories typically consist of standardized metal posts and mesh-like protective panels. The posts are generally square or round steel pipes, directly fixed to the concrete ground using expansion bolts via flanges at the bottom. The protective panels are then individually secured to the posts using bolts and nuts via specific connectors or brackets. The technical principle relies entirely on the strong clamping force provided by threaded fasteners to construct a rigid and stable physical barrier. The primary design goal is to ensure the structure's robustness and impact resistance to effectively isolate hazardous sources.

[0004] However, traditional guardrails designed for general industrial environments, with their sharp edges and rough connection structures, can cause serious product damage and production efficiency problems in specialized applications like film production. On film production lines, especially during start-up and equipment commissioning, wide and easily damaged film rolls need to be pulled through various equipment units. Because the posts and beams of traditional guardrails have sharp edges, and the connectors and bolt heads protrude outwards, the film is easily scratched or torn if it comes into contact with the guardrail due to electrostatic attraction or slight deviation. This not only directly results in a significant waste of film material but also forces operators to frequently stop the machine and repeat the tedious film-drawing process, severely impacting production continuity and efficiency. Furthermore, electrical components such as emergency stop switches and sensors installed on the guardrails are easily accidentally touched or damaged by the drifting film, leading to unnecessary downtime and equipment damage. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a protective structure for film production equipment, which aims to improve the problems of objects on the guardrail easily scratching the film, the film hitting the long strip of equipment and causing sudden stops, resulting in multiple film wastes, and the film damaging electrical appliances installed on the guardrail.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a protective structure for a thin film production equipment, including a support column, a protective net fixedly connected to one side of the support column, an arc-shaped protective rod provided on the outer wall of the support column, and a connecting component provided between the arc-shaped protective rod and the support column;

[0007] The connecting assembly includes a mounting pin that passes through the inside of the arc-shaped protective rod and is slidably connected to the inside of the support column. The support column has a slot inside, and a steel ball is disposed inside the mounting pin. The steel ball is fitted into the slot, and a hand-tightening bolt is threaded inside the mounting pin. One end of the hand-tightening bolt is fixedly connected to a conical column, the outer wall of which fits against the outer wall of the steel ball. A limit component is provided on the outer wall of the mounting pin.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes a limiting ring, the inner wall of which is fixedly connected to the outer wall of the mounting pin, and one side of the mounting pin is in contact with the outer wall of the arc-shaped protective rod.

[0010] As a further description of the above technical solution:

[0011] The support column is slidably connected to a base at its bottom, and a locking groove is provided inside the support column.

[0012] As a further description of the above technical solution:

[0013] The base is internally connected to a limiting plate, and a locking block is fixedly connected to one side of the limiting plate.

[0014] As a further description of the above technical solution:

[0015] The locking block is slidably connected inside the base, and the locking block is engaged with the locking groove.

[0016] As a further description of the above technical solution:

[0017] The base is equipped with a telescopic rod inside, and a spring is sleeved on the outer wall of the telescopic rod.

[0018] As a further description of the above technical solution:

[0019] One end of the telescopic rod and the spring are both fixedly connected to the other side of the limiting plate, and the other end of the telescopic rod and the spring are both fixedly connected to the inside of the base.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the installation pin is first inserted into the support column after passing through the arc-shaped guardrail. The installation pin is limited on one side of the arc-shaped guardrail by the limiting ring. The steel ball is fixed by embedding in the slot. This achieves the effect of preventing the film from scraping against the guardrail and facilitating the installation of the protective structure. It solves the problems of objects on the guardrail easily scratching the film, the film hitting the equipment and causing a sudden stop, resulting in multiple film wastes, and the film damaging the electrical appliances installed on the guardrail. This improves the practicality of the protective structure.

[0022] 2. In this utility model, the bottom of the support column is directly inserted into the base, and then the locking block inside the base is embedded in the locking groove to lock the base and the support column, thereby improving the stability of the guardrail and solving the problem that the traditional guardrail and base are easy to loosen when directly inserted into the base, thus improving the stability of the protective structure.

[0030] 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.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a protective structure for a film production equipment, including a support column 1, which serves as the main load-bearing and support unit of the entire protective structure. A protective net 2 is fixedly connected to one side of the support column 1, which forms a large-area physical isolation barrier to prevent personnel or objects from entering the dangerous area. An arc-shaped protective rod 3 is provided on the outer wall of the support column 1, which provides a smooth and rounded transition surface for the protruding part of the guardrail to prevent it from scratching the film. A connecting component is provided between the arc-shaped protective rod 3 and the support column 1, which enables quick and stable installation and disassembly of the arc-shaped protective rod and the support column.

[0032] The connecting assembly includes a mounting pin 5, which serves as the core component of the connection, acting as both the mounting shaft and the main body of the locking mechanism. The mounting pin 5 passes inside the arc-shaped protective rod 3, pre-assembling the mounting pin and the arc-shaped protective rod into an independent mounting unit. The mounting pin 5 is slidably connected inside the support column 1, allowing the mounting pin with the protective rod to be directly inserted into the mounting hole of the support column for initial positioning. The support column 1 has a slot 8 inside, serving as an internal locking receiving structure, providing a groove for the steel ball to be engaged. The mounting pin 5 contains a steel ball 7, which acts as a radially extendable locking ball, a key component for quick locking. The steel ball 7 engages with the slot 8; when the steel ball is pushed out and engaged in the slot, the axial locking of the mounting pin within the support column is completed, thus fixing the arc-shaped protective rod. The mounting pin 5 has a threaded connection to a hand-tightening bolt 6, which acts as the driving element for the locking mechanism, rotating to... The locking and unlocking mechanism is controlled by a conical column 15 fixedly connected to one end of the hand-tightening bolt 6. This column acts as a wedge, converting the rotational motion of the hand-tightening bolt into a radial thrust on the steel ball. The outer wall of the conical column 15 fits against the outer wall of the steel ball 7. Its conical slope allows the steel ball to be pushed outwards when the hand-tightening bolt is screwed in, thus locking it, and allows it to retract inwards when screwed out, thus unlocking it. A limit component is provided on the outer wall of the mounting pin 5, providing a physical stop for precisely positioning the insertion depth of the mounting pin. The limit component includes a limit ring 4, which acts as a positioning shoulder for the mounting pin, ensuring accurate and consistent installation. The inner wall of the limit ring 4 is fixedly connected to the outer wall of the mounting pin 5, making it a fixed structure on the mounting pin. One side of the mounting pin 5 fits against the outer wall of the arc-shaped protective rod 3. When the mounting pin is inserted into position, the limit ring abuts against the outer wall of the protective rod to prevent over-insertion, thus ensuring accurate locking.

[0033] Reference Figure 4 and Figure 5A base 9 is slidably connected to the bottom of the support column 1, which enables quick insertion assembly between the support column and the base. A locking groove 10 is provided inside the support column 1, serving as a locking recess at the lower end of the support column and a passive engagement part of the locking mechanism. A limiting plate 11 is slidably connected inside the base 9, acting as a movable base plate for the locking and reset mechanisms, supporting the locking block and spring. A locking block 14 is fixedly connected to one side of the limiting plate 11, allowing the locking block to move with the limiting plate to perform locking or unlocking actions. The locking block 14 is slidably connected inside the base 9, providing a pre-set guide path for accurate extension or retraction. The locking block 14 engages with the locking groove 10, automatically springing back when the support column is inserted into position. The base 9 is inserted into the locking groove of the support column, thereby achieving a firm lock between the base and the support column and preventing accidental dislodgement. The base 9 is equipped with a telescopic rod 12, which serves as a push rod for unlocking and a guide shaft for the internal moving components. A spring 13 is sleeved on the outer wall of the telescopic rod 12, which provides an elastic force for automatic reset of the locking mechanism. One end of the telescopic rod 12 and the spring 13 are fixedly connected to the other side of the limiting plate 11, which allows the pushing force of the spring and the pulling force of the telescopic rod to be effectively applied to the limiting plate, thereby controlling the movement of the locking block. The other end of the telescopic rod 12 and the spring 13 are fixedly connected to the inside of the base 9, which provides a fixed reaction force point for the spring and the telescopic rod, so that the entire spring locking mechanism can automatically return to the locked state after being operated by external force (such as pressing the telescopic rod).

[0034] Working principle: When using the protective structure of this film production equipment, firstly, when installing the arc-shaped protective rod 3, one side of the arc-shaped protective rod 3 is attached to the outer wall of the support column 1. Then, the mounting pin 5 is inserted into the support column 1 after passing through the arc-shaped protective rod 3. The mounting pin 5 is limited on one side of the arc-shaped protective rod 3 by the limiting ring 4. Then, the hand-tightening bolt 6 is turned to drive the conical column 15 to extend into the mounting pin 5. Then, the outer wall of the conical column 15 is attached to the steel ball 7, which drives the steel ball 7 to be embedded in the slot 8 for fixation. This achieves the effect of preventing the film from rubbing against the guardrail and facilitating the installation of the protective structure.

[0035] When the base 9 is installed, the bottom of the support column 1 is directly inserted into the base 9. Then, the locking block 14 inside the base 9 is embedded in the locking groove 10 to lock the base 9 and the support column 1. The locking block 14 slides in the base 9 through the limiting plate 11. Then, the locking block 14 is supported by the tension of the spring 13 so that the locking block 14 can be stably fitted into the support column 1, thereby improving the stability of the guardrail.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
