[0028] Example 1

[0029] This embodiment provides a bubble film packaging structure for wrapping bubble film on a film roll, such as Figure 1As shown, the bubble film packaging structure includes a first conveying component 1, a bubble film delivery component 2 and a film wrapping component 3. The rear section of the first conveying component 1 is arranged in parallel with the film wrapping component 3, and the film wrapping component 3 is located above the bubble film delivery component 2; the bubble film delivery component 2 conveys the bubble film to the bottom of the film wrapping component 3, the first conveying component 1 and the film wrapping component 3 move the film roll to the bubble film below the film wrapping component 3, and the film wrapping component 3 wraps the bubble film on the film roll.

[0030] Specifically, the bubble film packaging structure provided in this embodiment has an integral frame, which includes multiple vertical rods and horizontal rods. There is a cavity inside the entire frame, and the first conveying component 1 is inserted into the cavity, and the bubble film component 2 is fixed on the horizontal rod; there is a platform below the wrapping component 3, which is horizontally parallel to the rear section of the first conveying component 1.

[0031] With the above structure, the film roll is first conveyed to the connection between the first conveying component 1 and the wrapping component 3 by the first conveying component 1, and the bubble film component 2 is started to work, and the bubble film is conveyed to the platform directly below the wrapping component 3. Then the wrapping component 3 moves the film roll to the bubble film below the wrapping component 3, and the wrapping component 3 starts to work, so that the film roll rolls a circle on the bubble film, and the bubble film is wrapped on the film roll. It can be seen that in the entire process of wrapping the bubble film, no manual participation is required, and the automation of bubble film wrapping is realized, which solves the problems of high labor and safety hazards in manual film wrapping.

[0032] In a specific embodiment, the first conveying assembly 1 is conveyed in the form of a belt line, and the specific structure of the first conveying assembly 1 is:

[0033] It includes a conveying body made of aluminum profiles, one side of the conveying body is a belt conveying surface, and rollers are installed at both ends of the belt conveying surface, one of which is a driving roller for providing the power required for operation, and the other is a direction roller for controlling and adjusting the direction of operation; after the rollers are installed, the belt conveyor line is installed on the conveyor frame; a foot cup is installed at the bottom of the conveyor frame to prevent the bottom from being worn due to friction, and the height of the entire belt conveyor line can be adjusted through the foot cup to adapt to different production needs; in addition, adjusting screws are installed at the bottom of both ends of the frame of the belt conveyor line to facilitate the adjustment of the conveying slope of the belt conveyor line; the conveying speed of the belt conveyor line can be adjusted according to production needs, which requires the installation of a speed regulator on the conveyor frame. The position of the speed regulator is close to the electric control box to facilitate the connection circuit of the two.

[0034] This embodiment uses a belt line to convey the film roll, and there is no relative movement between the film roll and the conveyor line, so that the surface of the film roll will not be damaged.

[0035] In a specific embodiment, the bubble film packaging structure further includes a second conveying component 4, which is connected to the film wrapping component 3 and is used to convey the film roll wrapped with the bubble film.

[0036] Specifically, the second conveying component 4 is connected to the other end of the platform below the film wrapping component 3; after the bubble film is wrapped on the film roll on the platform, the film roll can be transported to a designated position through the second conveying component 4.

[0037] In a specific embodiment, the bubble film packaging structure further includes a film cutting assembly 5 , which is located above the second conveying assembly 4 and is used to cut off excess bubble films on both sides of the film roll.

[0038] At the film wrapping component 3 station, in order to better wrap the bubble film on the film roll, the length of the bubble film is generally greater than the axial length of the film roll. Therefore, when the bubble film is wrapped on the film roll, there will be excess bubble film at both ends of the film roll. At this time, the excess bubble film on both sides of the film roll can be cut off by the film cutting component 5.

[0039] In a specific embodiment, the bubble film packaging structure also includes a film plugging component 6, which is located above the second conveying component 4 and downstream of the film cutting component 5, and is used to plug the bubble films on both sides of the film roll into the holes on both sides of the film roll.

[0040] At the film cutting assembly 5 station, after the film cutting assembly 5 cuts off the excess bubble film on both sides of the film roll, some bubble film is still located on both sides of the film roll. At this time, the film cutting assembly 5 can be used to plug it into the holes on both sides of the film roll.

[0041] In a specific embodiment, the bubble film delivery assembly 2 includes a bubble film bracket 21, a bubble film roller 22, a film wrapping platform 23 and a first hot film cutting knife 24; the bubble film roller 22 is fixed on one side of the bubble film bracket 21, the film wrapping platform 23 is located on the other side of the bubble film bracket 21, and the bubble film on the bubble film roller 22 can be transported to the film wrapping platform 23, and the first hot film cutting knife 24 is located between the bubble film bracket 21 and the film wrapping platform 23.

[0042] Specifically, the bubble film support 21 comprises two stepped structures arranged opposite each other. The bubble film roller 22 is fixed to the bottom step, and the top step is flush with the film wrapping platform 23. A fixed plate is located on the side of the top step facing the film wrapping platform 23, and a first hot film cutting knife 24 is located on the fixed plate. Thus, the bubble film on the bubble film roller 22 is pulled, passing through the bottom of the fixed plate and flattened on the film wrapping platform 23. When the bubble film reaches the required length, the first hot film cutting knife 24 moves downward to cut the bubble film. The first hot film cutting knife 24 utilizes concentrated heat energy to melt and separate the bubble film.

[0043] In a specific embodiment, the bubble film delivery assembly 2 also includes a first double-sided tape unit 25 and a second double-sided tape unit 26. The first double-sided tape unit 25 is fixed to one end of the bubble film holder 21 for sticking the double-sided tape on the first side of the bubble film, and the second double-sided tape unit 26 is fixed to the other end of the bubble film holder 21 for sticking the double-sided tape on the second side of the bubble film; wherein the first side and the second side are the two ends of the bubble film facing one side of the film roll when the film roll is wrapped with the bubble film.

[0044] More specifically, the two step-like structures relatively arranged in the bubble film support 21 are respectively a first step-like structure and a second step-like structure. There is a gap between the first step-like structure and the second step-like structure, and the gap is approximately the axial length of the bubble film roller 22; between the lowest steps, the bubble film roller 22 is connected to the first step-like structure, and the other end is connected to the second step-like structure; between the middle steps, the first double-sided tape unit 25 is connected to the first step-like structure, and the second double-sided tape unit 26 is connected to the second step-like structure. In this way, in the process of the bubble film moving toward the wrapping platform 23, the first double-sided tape unit 25 is attached to one side of the bubble film, and the second double-sided tape unit 26 is attached to the other side of the bubble film, so that the bubble film can be conveniently attached to the film roll.

[0045] In a specific embodiment, the coating assembly 3 includes a coating bracket 31, a drive unit 32 and a roller unit 33. The roller unit 33 is fixed on the drive unit 32, and the end of the roller unit 33 can contact the film roll under the coating assembly 3. The drive unit 32 is connected to the coating bracket 31, and the drive unit 32 can move along the coating bracket 31.

[0046] More specifically, two groups of roller units 33 are provided. The two groups of roller units 33 have the same structure and both include two support rods. Each connecting rod corresponds to two rollers. Both connecting rods are connected to the drive unit 32, but the directions of the two connecting rods are different, that is, there is an angle between the two connecting rods.

[0047] During the wrapping process, after the bubble film of the required length is spread on the wrapping platform 23, the driving unit 32 drives the entire roller unit 33 to move toward the direction close to the first conveying component 1, and then under the action of the roller unit 33, the film roll located between the wrapping platform 23 and the first conveying component 1 is moved to the bubble film of the wrapping platform 23. Due to the action of the first double-sided tape unit 25, one side of the bubble film has double-sided tape, and at this time the double-sided tape fixes the starting end of the bubble film to the film roll together, and then the entire roller unit 33 slowly moves toward the direction away from the first conveying component 1. At the same time, under the action of the roller unit 33, the film roll also moves slowly until it moves to the end of the bubble film. Due to the action of the second double-sided tape unit 26, the other side of the bubble film also has double-sided tape, and at this time the double-sided tape fixes the terminal end of the bubble film to the film roll, completing the entire wrapping process.

[0048] It should be noted that in this embodiment, it is necessary to ensure that the length of the film wrapping platform in the direction of movement along the film roll cannot be less than the axial length of the radial cross-section of the film roll to ensure that one circle of film wrapping can be completed.

[0049] In a specific embodiment, the driving unit 32 includes a first motor 321, a gear 322, a rack 323 and a driving bracket 324. The first motor 321 is fixed on the driving bracket 324, and the output end of the first motor 321 is connected to the gear 322. The gear 322 is engaged with the rack 323 set on the membrane bracket 31.

[0050] In this way, after adopting the above structure, the first motor 321 works, driving the gear 322 to rotate, and since the gear 322 is engaged with the rack 323, and the rack 323 is fixed on the membrane bracket 31, the driving unit 32 can move back and forth along the membrane bracket 31; and the roller unit 33 is connected to the driving unit 32, so it can drive the entire roller unit 33 to move back and forth.

[0051] In a specific embodiment, at least two groups of roller units 33 are provided; each group of roller units 33 includes a first cylinder 331 and a roller 332, the first cylinder 331 is fixed on the driving bracket 324, and the roller 332 is connected to the output end of the first cylinder 331; in this way, during the reciprocating motion of the piston in the first cylinder 331, the roller 332 also performs an up and down reciprocating motion, which can push the film roll to move on the one hand, and on the other hand, it can also compress the bubble film on the film roll.

[0052] In a specific embodiment, the second conveying assembly 4 includes a conveying frame 41, a second motor 42, a screw and a supporting seat 43 for placing the film roll wrapped with bubble film. The output end of the second motor 42 is connected to the screw, and the output end of the screw abuts against the supporting seat 43, driving the supporting seat 43 to move back and forth on the conveying frame 41.

[0053] Among them, the supporting seat 43 is used to place the film roll wrapped with bubble film, and the film roll is moved from the film wrapping platform 23 to the supporting seat 43 with the help of the force of the roller unit 33; and in order to better achieve movement and fixation, the middle of the supporting seat 43 is a recess. Specifically, the surface of the supporting seat 43 includes an inclined first surface and an inclined second surface. The first surface is a surface close to the film wrapping platform 23, which is inclined downward along the direction from the film wrapping platform 23 to the film wrapping platform 23; the second surface is a surface away from the film wrapping platform 23, which is inclined upward along the direction from the film wrapping platform 23 to the film wrapping platform 23; that is, when the film roll moves from the film wrapping platform 23 to the supporting seat 43, it needs to go through a downhill slope, which can be better moved; after moving into place, it is just stuck in the recess, and both sides of the film roll are uphill, which can better achieve fixation.

[0054] In a specific embodiment, the film cutting assembly 5 has two groups, each group of film cutting assemblies 5 includes a second cylinder 51, a second hot film cutting knife 52 and a film cutting bracket 53, the second cylinder 51 is fixed on the film cutting bracket 53, and the second hot film cutting knife 52 is located at the output end of the second cylinder 51; wherein, the distance between the two second hot film cutting knives 52 is not less than the axial length of the film roll.

[0055] Specifically, as the piston in the second cylinder 51 reciprocates, the second hot film cutting knife 52 performs an up and down reciprocating motion, thereby cutting off excess bubble films on both sides of the film roll.

[0056] In a specific embodiment, the membrane plugging assembly 6 has two groups, and each group of membrane plugging assemblies 6 includes a third cylinder and a cylindrical membrane plugging member. The membrane plugging member is located at the output end of the third cylinder and is used to plug the bubble membranes at both ends of the film roll into the corresponding holes; wherein the shape and size of the membrane plugging member correspond to the shape and size of the holes on both sides of the film roll, and the third cylinder drives the membrane plugging member to work, thereby plugging the bubble membranes at both ends of the film roll into the corresponding holes.

[0057] The specific working process of the bubble film packaging structure provided in this embodiment is as follows:

[0058] (1) The film roll is conveyed to the connection between the first conveying assembly 1 and the film wrapping assembly 3 by the first conveying assembly 1, specifically: the motor is operated to drive the driving roller and the direction roller to work, and the belt conveyor line is operated accordingly, and the film roll on the belt conveyor line is conveyed to the connection between the first conveying assembly 1 and the film wrapping assembly 3;

[0059] (2) The bubble film delivery assembly 2 works to deliver the bubble film to the platform directly below the film wrapping assembly 3. Specifically, the bubble film on the bubble film roller 22 moves toward the film wrapping platform 23. During the movement, the first double-sided tape unit 25 is attached to one side of the bubble film, and the second double-sided tape unit 26 is attached to the other side of the bubble film.

[0060] (3) The wrapping assembly 3 works, moves the film roll to the bubble film below the wrapping assembly 3, and then begins wrapping, specifically: the driving unit 32 drives the entire roller unit 33 to move toward the direction close to the first conveying assembly 1, and then under the action of the roller unit 33, the film roll located between the wrapping platform 23 and the first conveying assembly 1 is moved to the bubble film of the wrapping platform 23. Due to the action of the first double-sided adhesive unit 25, one side of the bubble film has double-sided adhesive, and at this time the double-sided adhesive fixes the starting end of the bubble film to the film roll, and then the entire roller unit 33 slowly moves toward the direction away from the first conveying assembly 1. At the same time, under the action of the roller unit 33, the film roll also slowly moves until it moves to the end of the bubble film. Due to the action of the second double-sided adhesive unit 26, the other side of the bubble film also has double-sided adhesive, and at this time the double-sided adhesive fixes the terminal end of the bubble film to the film roll, completing the entire wrapping process;

[0061] (4) The excess bubble film on both sides of the film roll is cut off by the film cutting assembly 5. Specifically, the piston in the second cylinder 51 reciprocates, and the second hot film cutting knife 52 then reciprocates up and down. In this way, the excess bubble film on both sides of the film roll can be cut off;

[0062] (5) The bubble membranes at both ends of the film roll are plugged into the corresponding holes through the membrane plugging component 6. Specifically, the third cylinder drives the membrane plugging component to work, thereby plugging the bubble membranes at both ends of the film roll into the corresponding holes.

[0063] The bubble film packaging structure provided in this embodiment does not require manual participation in the entire bubble film wrapping process, thus realizing the automation of bubble film wrapping and solving the problems of high labor workload and potential safety hazards in manual film wrapping. At the same time, it has a simple structure and stable operation, and can complete the bubble film wrapping of plastic film in one go.
