Description

Technical Field

[0001] The present invention relates to the technical field of bubble films, in particular to a bubble film with high-efficiency buffering and protective effects and a processing technology thereof. Background Art

[0002] Bubble film is made of high-pressure polyethylene as the main raw material, with whitening agent, opening agent and other auxiliary materials added. It is extruded and blister-formed into bubbles at a high temperature of about 230 degrees. It is a new type of plastic packaging material with light texture, good transparency, non-toxic and odorless. It can prevent moisture, cushion and keep heat for products.

[0003] Existing patent publication number: CN109679263B discloses a high-strength flame-retardant bubble film, which solves the problem that the strength of the flame-retardant bubble film is affected and limited by the addition of flame retardants. The key technical solution is a high-strength flame-retardant bubble film, comprising a base film and a blister film that are bonded and fixed to each other. The blister film is distributed with multiple blister bubbles. The base film and the blister film are made of modified PE. The modified PE contains the following raw materials in parts by weight: 23-28 parts of LDPE, 47-55 parts of LLDPE, 22-26 parts of HDPE, 1-3 parts of an anti-blocking agent, 3-6 parts of a binder, and 5-7 parts of a flame retardant. The binder is one or two compounds selected from sorbic acid and 2,4-pentadienoic acid. The flame retardant is DOPO, which improves the flame retardant properties of the bubble film while reducing the reduction in the strength of the flame-retardant bubble film caused by the flame retardant.

[0004] However, applications similar to the above-mentioned bubble films also have the following defects:

[0005] In order to effectively protect the product, the existing bubble film needs to wrap the product layer by layer to increase the protection thickness, thereby improving the protection effect. That is, the protection effect of a single layer of bubble film is easily insufficient and the puncture resistance is poor.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a bubble film with high-efficiency cushioning and protective effect and its processing technology are proposed. Summary of the Invention

[0007] In view of the deficiencies in the prior art, the present invention provides a bubble film with efficient buffering and protective effects and a processing technology thereof, which solves the problems raised in the above-mentioned background technology.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a bubble film with efficient buffering and protection effect, comprising a first rubber film and a polyethylene film, the surface of the first rubber film is bonded to the second rubber film, and the surfaces of the first rubber film and the second rubber film are both provided with rubber bubbles, the polyethylene film is attached to the surfaces of the first rubber film and the second rubber film, and the surface of the polyethylene film is provided with film bubbles, and the rubber bubbles are located inside the film bubbles.

[0009] A processing technology for a bubble film with a high-efficiency cushioning and protective effect, the processing technology comprising the following steps:

[0010] Step 1: The mixed polyethylene raw material is sent to an extruder for heating and melting. The raw material is melted into a paste-like resin and then sent to a film blowing machine. At the outlet of the film blowing machine, air is injected by pulling to form a cylindrical film. The cylindrical film is then cut into two parts and wound up to obtain two rolls of polyethylene film.

[0011] Step 2: The rubber particles are sent to an extruder for heating and melting. The melted rubber paste is then pressed into a thin film structure, i.e., a rubber film. The rubber mold is then rolled by a roller with hemispherical bumps to thin the surface where it contacts the bumps, thereby obtaining the first and second rubber films.

[0012] Step 3: Glue is applied to the surfaces of the first rubber film and the second rubber film and they are overlapped and pressed together to obtain a combined rubber mold. The combined rubber mold and the two rolls of polyethylene film are then transported in and out. During the transportation process, they pass through the pressing and gas injection equipment for subsequent processing. Specifically, the combined rubber mold and the two rolls of polyethylene film pass between the upper and lower rotating rollers. At this time, the rubber mold is in the middle and the polyethylene films are located on the upper and lower sides of the rubber mold for transportation;

[0013] Step 4: The upper rotating roller and the lower rotating roller press the rubber mold and the polyethylene film by rotating. Specifically, the driving motor drives the upper rotating roller to rotate. At the same time, the upper rotating roller drives the lower rotating roller to rotate in the opposite direction through the gear. When the upper rotating roller and the lower rotating roller rotate, the bubble groove rotates to the surface of the polyethylene film. At this time, the air pump generates negative air pressure inside the bubble groove through the air supply channel and the air suction channel, so that the part of the polyethylene film surface inside the bubble groove is sucked up and becomes vacuum bubbles, i.e., film bubbles;

[0014] Step 5: After bubbles are formed on the surface of the polyethylene film, it continues to be transported. During the transportation process, the electric telescopic rod is extended to make the air injection needle move obliquely and insert into the rubber mold, specifically into the part where the thickness of the rubber mold becomes thinner. At this time, the gas extracted by the vacuum pump enters the part where the thickness of the rubber mold becomes thinner along the air pipe, the air injection cylinder, and the air injection needle, causing the part to swell to form rubber bubbles. At this point, a bubble film with efficient buffering and protection effect can be obtained.

[0015] Furthermore, the pressed gas injection equipment includes a bracket, an upper rotating roller is connected to the inner side of the bracket, and a lower rotating roller is arranged below the upper rotating roller. The outer walls of the ends of the lower rotating roller and the upper rotating roller are provided with gears, and the gears are engaged with each other. The end of the upper rotating roller is connected to a drive motor.

[0016] Furthermore, the lower rotating roller is rotatably connected to the bracket, and the lower rotating roller is transmission-connected to the upper rotating roller via a gear.

[0017] Furthermore, bubble grooves are provided on the surfaces of the lower rotating roller and the upper rotating roller, and air supply channels are provided inside the lower rotating roller and the upper rotating roller. Air suction channels are distributed around the air supply channels, and an end of the air supply channel away from the drive motor is connected to an air pump through a pipeline.

[0018] Furthermore, the gas delivery channel is connected to the bubble groove through the air intake channel, and the bubble groove has a semicircular structure.

[0019] Furthermore, an air injection assembly is provided on the right side of the upper rotating roller, and the air injection assembly includes an electric telescopic rod, an air injection cylinder and an air injection needle. The bottom of the electric telescopic rod is connected to the air injection cylinder, and the bottom of the air injection cylinder is fixed with the air injection needle.

[0020] Furthermore, the electric telescopic rod is arranged at an angle, and the electric telescopic rod is fixedly connected to the bracket.

[0021] Furthermore, the gas injection assembly also includes a gas delivery pipe, and the top of the gas injection cylinder is connected to the gas delivery pipe.

[0022] Furthermore, one end of the air supply pipe away from the air injection cylinder is connected to the air extraction pump, and the air injection cylinder is connected to the air extraction pump through the air supply pipe.

[0023] The present invention provides a bubble film with high-efficiency cushioning and protective effects and a processing technology thereof, which has the following beneficial effects:

[0024] 1. The bubble film with efficient cushioning and protective effects and its processing technology are characterized by a first rubber film and a second rubber film arranged between polyethylene films. The rubber material has excellent flexibility, pressure resistance, puncture resistance and cushioning properties. Therefore, without affecting the lightness and softness of the existing bubble film, the combination with the rubber bubbles filled with air is conducive to enhancing the pressure resistance and recovery of the existing bubble film, thereby improving the protective effect of the bubble film.

[0025] 2. Compared with the existing bubble film production process, the bubble film with efficient cushioning and protection effect and its processing technology can use an extruder for batch operation, that is, the polyethylene raw material and rubber particles are heated, melted and extruded separately, and the rubber mold can be obtained by simply adding a rolling step, so as to achieve the purpose of achieving a large improvement at a low cost, and the production process steps are simple, easy to understand and easy to implement.

[0026] 3. The bubble film with efficient cushioning and protection effect and its processing technology, the vacuum pump vacuums and cooperates with the bubble groove to make the surface of the polyethylene film sucked up to form vacuum bubbles, and the vacuum pump exhausts and cooperates with the air injection needle to inject air into the rubber mold to form rubber bubbles, thereby making full use of the vacuum pump and avoiding waste of resources.

[0033] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0034] like Figure 1 As shown, the present invention provides a technical solution: a bubble film with efficient buffering and protective effects, comprising a first rubber film 1 and a polyethylene film 4, wherein a second rubber film 2 is bonded to the surface of the first rubber film 1, and rubber bubbles 3 are provided on the surfaces of the first rubber film 1 and the second rubber film 2, and the polyethylene film 4 is attached to the surfaces of the first rubber film 1 and the second rubber film 2, and film bubbles 5 are provided on the surface of the polyethylene film 4, and the rubber bubbles 3 are located inside the film bubbles 5;

[0035] The specific operation is as follows: a first rubber film 1 and a second rubber film 2 are arranged between the polyethylene film 4. The well-known rubber material has excellent flexibility, pressure resistance, puncture resistance and cushioning properties. Therefore, without affecting the lightness and softness of the existing bubble film, the combination with the rubber bubbles 3 filled with air is beneficial to enhance the pressure resistance and recovery of the existing bubble film, thereby improving the protective effect of the bubble film.

[0036] like Figure 2-Figure 5 As shown, a processing technology of bubble film with high-efficiency cushioning and protective effect includes the following steps:

[0037] Step 1: The mixed polyethylene raw material is sent to an extruder for heating and melting. After the raw material is melted into a paste-like resin, it is sent to a film blowing machine. At the outlet of the film blowing machine, air is injected by pulling to form a cylindrical film. The cylindrical film is then cut into two parts and rolled up, thereby obtaining two rolls of polyethylene film 4;

[0038] Step 2: The rubber particles are sent to an extruder for heating and melting. The melted rubber paste is then pressed into a thin film structure, i.e., a rubber film. The rubber film is then rolled by a roller with hemispherical bumps to reduce the thickness of the surface where it contacts the bumps, thereby obtaining the first rubber film 1 and the second rubber film 2.

[0039] Step 3: Glue is applied to the surfaces of the first rubber film 1 and the second rubber film 2 and they are overlapped and pressed together to obtain a combined rubber mold. The combined rubber mold and the two rolls of polyethylene film 4 are then transported in and out. During the transportation process, they pass through the pressing and gas injection equipment for subsequent processing. Specifically, the combined rubber mold and the two rolls of polyethylene film 4 pass between the upper rotating roller 7 and the lower rotating roller 8. At this time, the rubber mold is located in the middle and the polyethylene film 4 is located on the upper and lower sides of the rubber mold for transportation;

[0040] Step 4: The upper rotating roller 7 and the lower rotating roller 8 press the rubber mold and the polyethylene film 4 by rotating. Specifically, the driving motor 10 drives the upper rotating roller 7 to rotate. While the upper rotating roller 7 rotates, the gear 9 drives the lower rotating roller 8 to rotate in the same direction. While the upper rotating roller 7 and the lower rotating roller 8 rotate, the bubble groove 11 rotates to the surface of the polyethylene film 4. At this time, the air pump 14 generates negative air pressure inside the bubble groove 11 through the air supply channel 12 and the air suction channel 13, so that the part of the surface of the polyethylene film 4 inside the bubble groove 11 is sucked up and becomes a vacuum bubble, i.e., a film bubble 5;

[0041] Step 5: After the film bubble 5 is formed on the surface of the polyethylene film 4, it continues to be transported. During the transportation process, the electric telescopic rod 1501 is extended to make the air injection needle 1503 move obliquely and insert into the rubber mold, specifically, insert into the part where the thickness of the rubber mold becomes thinner. At this time, the gas extracted by the vacuum pump 14 enters the part where the thickness of the rubber mold becomes thinner along the air pipe 1504, the air injection cylinder 1502, and the air injection needle 1503, causing the part to swell to form a rubber bubble 3. At this point, a bubble film with a high-efficiency buffering and protection effect can be obtained.

[0042] like Figure 2-Figure 3 As shown, the pressing and gas injection equipment includes a bracket 6, an upper rotating roller 7 is connected to the inner side of the bracket 6, and a lower rotating roller 8 is arranged below the upper rotating roller 7, gears 9 are provided on the outer walls of the ends of the lower rotating roller 8 and the upper rotating roller 7, and the gears 9 are meshed with each other, and a driving motor 10 is connected to the end of the upper rotating roller 7, the lower rotating roller 8 is rotatably connected to the bracket 6, and the lower rotating roller 8 is transmission-connected to the upper rotating roller 7 through the gear 9, bubble grooves 11 are provided on the surfaces of the lower rotating roller 8 and the upper rotating roller 7, and gas transmission channels 12 are provided inside the lower rotating roller 8 and the upper rotating roller 7, and suction channels 13 are distributed around the gas transmission channel 12, and the end of the gas transmission channel 12 away from the driving motor 10 is connected to an air pump 14 through a pipeline, the gas transmission channel 12 is connected to the bubble groove 11 through the suction channel 13, and the bubble groove 11 is semicircular in structure;

[0043] The specific operation is as follows: the surfaces of the first rubber film 1 and the second rubber film 2 are coated with glue and overlapped and pressed together, and then the rubber mold combined into one and the two rolls of polyethylene film 4 are transported in and out. During the transportation process, the rubber mold combined into one and the two rolls of polyethylene film 4 pass between the upper rotating roller 7 and the lower rotating roller 8. At this time, the rubber mold is located in the middle and the polyethylene film 4 is located on the upper and lower sides of the rubber mold for transportation. At the same time, the driving motor 10 drives the upper rotating roller 7 to rotate. While the upper rotating roller 7 rotates, the gear 9 drives the lower rotating roller 8 to rotate in opposite directions. While the upper rotating roller 7 and the lower rotating roller 8 rotate, the bubble groove 11 will rotate to the surface of the polyethylene film 4. At this time, the vacuum pump 14 generates negative air pressure inside the bubble groove 11 through the air supply channel 12 and the air suction channel 13, so that the part of the surface of the polyethylene film 4 located inside the bubble groove 11 is sucked up and becomes a vacuum bubble, namely, a membrane bubble 5.

[0044] like Figure 3-Figure 5As shown, a gas injection assembly 15 is provided on the right side of the upper rotating roller 7. The gas injection assembly 15 includes an electric telescopic rod 1501, a gas injection cylinder 1502 and a gas injection needle 1503. The bottom of the electric telescopic rod 1501 is connected to the gas injection cylinder 1502, and the bottom of the gas injection cylinder 1502 is fixed with the gas injection needle 1503. The electric telescopic rod 1501 is arranged obliquely and is fixedly connected to the bracket 6. The gas injection assembly 15 also includes a gas pipe 1504. The top of the gas injection cylinder 1502 is connected to the gas pipe 1504. The end of the gas pipe 1504 away from the gas injection cylinder 1502 is connected to the air pump 14, and the gas injection cylinder 1502 is communicated with the air pump 14 through the gas pipe 1504.

[0045] The specific operation is as follows: after the film bubble 5 is formed on the surface of the polyethylene film 4, it continues to be transported. During the transportation process, the electric telescopic rod 1501 is extended to make the gas injection needle 1503 move obliquely and insert into the rubber mold, specifically, it is inserted into the part where the thickness of the rubber mold becomes thinner. At this time, the gas extracted by the vacuum pump 14 enters the part where the thickness of the rubber mold becomes thinner along the gas pipe 1504, the gas injection cylinder 1502, and the gas injection needle 1503, causing the part to swell and form a rubber bubble 3. The vacuum pump 14 evacuates air and cooperates with the bubble groove 11 to make the surface of the polyethylene film 4 sucked up and become a vacuum bubble, and the vacuum pump 14 exhausts air and cooperates with the gas injection needle 1503 to inject air into the rubber mold to form a rubber bubble 3, thereby making full use of the vacuum pump 14 and avoiding waste of resources.

[0046] In summary, if Figure 1-Figure 5 The bubble film with high-efficiency cushioning and protective effect and its processing technology are shown. When in use, the mixed polyethylene raw material is first sent to an extrusion molding machine for heating and melting. The raw material is melted into a paste-like resin and then sent to a film blowing machine. At the outlet of the film blowing machine, air is injected by pulling to form a cylindrical film. Then, the cylindrical film is cut into two parts and rolled up to obtain two rolls of polyethylene film 4. Rubber particles are sent to an extrusion molding machine for heating and melting. The melted rubber paste is pressed to form a film-like structure, that is, a rubber film. The rubber mold is rolled by a roller with hemispherical protrusions to reduce the thickness of the surface in contact with the protrusions, thereby obtaining a first rubber film 1 and a second rubber film 2.

[0047] The surfaces of the first rubber film 1 and the second rubber film 2 are coated with glue and overlapped and pressed together to obtain a combined rubber mold. The combined rubber mold and the two rolls of polyethylene film 4 are then transported in and out. During the transportation process, they pass through a pressing and gas injection device for subsequent processing. Specifically, the combined rubber mold and the two rolls of polyethylene film 4 pass between an upper rotating roller 7 and a lower rotating roller 8. At this time, the rubber mold is located in the middle and the polyethylene films 4 are located on the upper and lower sides of the rubber mold for transportation;

[0048] The upper rotating roller 7 and the lower rotating roller 8 press the rubber mold and the polyethylene film 4 by rotating. Specifically, the driving motor 10 drives the upper rotating roller 7 to rotate. While the upper rotating roller 7 rotates, the gear 9 drives the lower rotating roller 8 to rotate in the opposite direction. While the upper rotating roller 7 and the lower rotating roller 8 rotate, the bubble groove 11 rotates to the surface of the polyethylene film 4. At this time, the air pump 14 generates negative air pressure inside the bubble groove 11 through the air supply channel 12 and the air suction channel 13, so that the part of the surface of the polyethylene film 4 inside the bubble groove 11 is sucked up and becomes a vacuum bubble, i.e., a film bubble 5.

[0049] After the film bubble 5 is formed on the surface of the polyethylene film 4, it continues to be transported. During the transportation process, the electric telescopic rod 1501 is extended, so that the air injection needle 1503 moves obliquely and is inserted into the interior of the rubber mold, specifically into the part where the thickness of the rubber mold becomes thinner. At this time, the gas extracted by the vacuum pump 14 enters the part where the thickness of the rubber mold becomes thinner along the air pipe 1504, the air injection cylinder 1502, and the air injection needle 1503, causing the part to bulge to form a rubber bubble 3. At this point, a bubble film with a high-efficiency buffering and protection effect can be obtained.
