Description

Technical Field

[0001] This utility model relates to the field of plastic film technology, and in particular to an antistatic environmentally friendly plastic film. Background Technology

[0002] Plastic film, as a widely used packaging and industrial material, plays an important role in various fields of modern society. From food packaging and electronic appliance encapsulation to agricultural covering and construction engineering, plastic film meets many different needs with its good flexibility, barrier properties, processing performance, and economy. With the continuous advancement of technology and people's increasing demands for product performance, the development of a plastic film that integrates antistatic properties, environmental protection, and high performance has become an inevitable trend in the industry. Antistatic environmentally friendly plastic film has emerged in this context, aiming to solve the static electricity and environmental problems of traditional plastic films and meet the diverse needs of modern industry and life for plastic films. It has broad market prospects and important practical significance.

[0003] Most existing antistatic environmentally friendly plastic films are only compatible with one type of connector when stored. When the connector does not match the inner wall of the installation cylinder, the film body will shake, causing the film body to rub and collide with the inner wall of the installation cylinder, affecting the integrity and appearance quality of the film.

[0004] Therefore, there is an urgent need to provide an antistatic, environmentally friendly plastic film to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an antistatic environmentally friendly plastic film.

[0006] To solve the above-mentioned technical problems, the present invention provides an antistatic environmentally friendly plastic film, including an installation cylinder, a film body installed on the outer wall of the installation cylinder, an adjustment component provided on the inner wall of the installation cylinder, a connecting member clamped on the adjustment component, and an electrostatic protection component provided inside the film body.

[0007] The present invention is further configured such that: the adjustment assembly includes two adjustment components fixedly connected to the inner wall of the mounting cylinder, each of the two adjustment components having a spring slidably connected to its inner wall, each of the two adjustment components having a limit ring slidably connected to the corresponding surface of its inner wall, each of the two limit rings having an adjustment rod fixedly connected to the corresponding surface of its outer wall, and each of the two adjustment rods having a clamping plate fixedly connected to its corresponding end.

[0008] The above technical solution involves first sliding the connector towards the inside of the mounting cylinder until the top of the connector contacts the tops of the two clamping plates. Then, the contact force compresses the two clamping plates towards the mounting cylinder. Simultaneously, the two clamping plates drive the corresponding adjusting rods to move synchronously. Then, the two adjusting rods drive the corresponding limiting rings to move synchronously, and the two limiting rings also compress the corresponding springs, causing the two springs to have an outward elastic force, thereby allowing the inner wall of the clamping plate to clamp the outer wall of the connector.

[0009] The present invention is further configured such that the two adjusting members, the spring, the limiting ring, the adjusting rod, and the clamping plate are all parallel to each other.

[0010] The above technical solution ensures that the spring is subjected to consistent force in the axial direction, preventing twisting or abnormal deformation. This ensures consistent mechanical properties during each compression and rebound, keeping the clamping force of the clamping plate on the connector within a relatively stable range.

[0011] The present invention is further configured such that the inner walls of both adjusting members are fitted with the outer walls of the corresponding limiting rings, and both adjusting rods pass through one end of the adjusting members.

[0012] Through the above technical solution, the fitting structure ensures that the limiting ring can only move in a straight line along the inner wall of the adjusting component, without shaking or deviating, thus guaranteeing the stability and accuracy of the entire adjustment process.

[0013] The present invention is further configured such that: the electrostatic protection component includes a base layer disposed on the outer wall of the film body, an antistatic layer disposed on the inner wall of the base layer, a barrier layer disposed on the inner wall of the antistatic layer, an adhesive layer disposed on the inner wall of the barrier layer, and a printing layer disposed on the inner wall of the adhesive layer.

[0014] Through the above technical solutions, the base layer provides basic physical support and strength guarantee for the entire electrostatic protection component, the antistatic layer effectively reduces the accumulation of static electricity on the film surface and improves the safety and reliability of the film. At the same time, the barrier layer can effectively block the penetration of substances such as oxygen, water vapor and odors in the external environment, the adhesive layer plays a role in firmly bonding the various functional layers together, and the printing layer can improve product recognition.

[0015] The present invention is further configured such that the bottom of the base layer fits into the top of the antistatic layer, and the base layer and the antistatic layer are respectively made of polyethylene and polyether ester amide.

[0016] The above technical solution enables a tight connection between the base layer and the antistatic layer, and the chemical corrosion resistance ensures that the film will not be corroded when it comes into contact with various chemicals, thereby protecting the internal antistatic layer and other functional layers. At the same time, polyether ester amide can effectively reduce the surface resistance of the film, allowing the charge to leak out quickly, thereby preventing the accumulation of static electricity.

[0017] The present invention is further configured such that the bottom of the barrier layer and the top of the adhesive layer fit together, and the barrier layer and the adhesive layer are respectively made of silicon dioxide and hot melt adhesive.

[0018] The above technical solutions ensure the integrity and reliability of the entire film structure and extend the service life of the film. Silica can effectively block the permeation of substances such as oxygen, carbon dioxide, and water vapor, providing a good protective environment for the packaged items. At the same time, hot melt adhesive can quickly fill the tiny gaps between the barrier layer and other adjacent layers to achieve rapid bonding.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting an adjustment component, this utility model can make precise adjustments according to the specific size of the connector, so that the plastic film fits tightly with the connector, avoiding film shaking caused by mismatch. At the same time, it also prevents scratches and damage to the film surface, protecting the integrity and performance of the film.

[0021] 2. By setting up an electrostatic protection component, this utility model can reduce the resistance of the film surface, allowing the charge to leak out quickly, thereby effectively preventing the accumulation of static electricity, keeping the film surface clean, and ensuring that it can function normally in various environments.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Please see Figure 1 - Figure 5 An antistatic environmentally friendly plastic film includes an installation cylinder 1. A film body 4 is installed on the outer wall of the installation cylinder 1, and an adjustment assembly 3 is provided on the inner wall of the installation cylinder 1. The adjustment assembly 3 includes two adjustment members 301 fixedly connected to the inner wall of the installation cylinder 1. Springs 302 are slidably connected to the inner walls of the two adjustment members 301. Limit rings 303 are slidably connected to corresponding surfaces of the inner walls of the two adjustment members 301. Adjusting rods 304 are fixedly connected to corresponding surfaces of the outer walls of the two limit rings 303. Clamping plates 305 are fixedly connected to corresponding ends of the two adjusting rods 304. First, the connecting member 2 is slid into the installation cylinder 1 until the top of the connecting member 2 abuts against the tops of the two clamping plates 305. Then, the force of the abutment squeezes the two clamping plates 305 towards the installation cylinder 1. At the same time, the two clamping plates 305 drive the corresponding adjusting rods 304 to move synchronously. Then, the two adjusting rods 304 drive the corresponding limit rings 303. The synchronous movement, with the two limiting rings 303 compressing the corresponding springs 302, creates an outward elastic force in the two springs 302. This allows the inner wall of the clamping plate 305 to clamp the outer wall of the connecting piece 2. The two adjusting pieces 301, springs 302, limiting rings 303, adjusting rods 304, and clamping plate 305 are all parallel to each other. This ensures that the springs 302 experience consistent force in the axial direction, preventing twisting or abnormal deformation. This ensures consistent mechanical properties during each compression and rebound, keeping the clamping force of the clamping plate 305 on the connecting piece 2 within a relatively stable range. The inner walls of the two adjusting pieces 301 are fitted with the outer walls of the corresponding limiting rings 303, and the two adjusting rods 304 penetrate one end of the adjusting piece 301. This fitted structure ensures that the limiting rings 303 can only move linearly along the inner wall of the adjusting piece 301, without wobbling or shifting, thus guaranteeing the stability and accuracy of the entire adjustment process.

[0030] like Figure 3 and Figure 5As shown, the adjusting component 3 holds the connector 2, and the film body 4 is equipped with an electrostatic protection component 5. The electrostatic protection component 5 includes a base layer 501 disposed on the outer wall of the film body 4, an antistatic layer 502 disposed on the inner wall of the base layer 501, a barrier layer 503 disposed on the inner wall of the antistatic layer 502, an adhesive layer 504 disposed on the inner wall of the barrier layer 503, and a printed layer 505 disposed on the inner wall of the adhesive layer 504. The base layer 501 provides basic physical support and strength guarantee for the entire electrostatic protection component 5. The antistatic layer 502 effectively reduces the accumulation of static electricity on the film surface and improves the safety and reliability of the film. At the same time, the barrier layer 503 can effectively block the penetration of oxygen, water vapor, odors and other substances in the external environment. The adhesive layer 504 firmly bonds the various functional layers together. The printed layer 505 can improve product recognition. The bottom of the base layer 501 fits into the top of the antistatic layer 502, and the base layer 501... The antistatic layer 502 is made of polyethylene and polyether ester amide, respectively. This allows for a tight connection between the base layer 501 and the antistatic layer 502. Its chemical resistance ensures that the film will not be corroded when exposed to various chemicals, thus protecting the internal antistatic layer 502 and other functional layers. Simultaneously, polyether ester amide effectively reduces the surface resistance of the film, allowing charge to dissipate quickly and preventing the accumulation of static electricity. The bottom of the barrier layer 503 fits snugly against the top of the adhesive layer 504. The barrier layer 503 and adhesive layer 504 are made of silica and hot melt adhesive, respectively. This ensures the integrity and reliability of the entire film structure and extends the film's service life. Silica effectively blocks the permeation of oxygen, carbon dioxide, water vapor, and other substances, providing a good protective environment for the packaged items. Meanwhile, the hot melt adhesive quickly fills the tiny gaps between the barrier layer 503 and other adjacent layers, achieving rapid adhesion.

[0031] In use, the connector 2 is first slid into the mounting cylinder 1 until the top of the connector 2 contacts the top of the two clamping plates 305. Then, the force of the contact compresses the two clamping plates 305 into the mounting cylinder 1. At the same time, the two clamping plates 305 drive the corresponding adjusting rods 304 to move synchronously. Then, the two adjusting rods 304 drive the corresponding limiting rings 303 to move synchronously. The two limiting rings 303 also compress the corresponding springs 302, so that the two springs 302 have an outward elastic force, thereby allowing the inner wall of the clamping plate 305 to clamp the outer wall of the connector 2.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
