Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a material film splicing heating and automatic conveying device. Background Technology

[0002] The traditional membrane roll unwinding process generally involves power output to the membrane support cylinder, which, along with the membrane roll top wheel, drives the membrane roll to unwind actively. However, different membrane applications require different unwinding processes, which may vary depending on the membrane roll being formed.

[0003] For example, Chinese Patent Publication No. 202221333153.4, published on September 23, 2022, discloses an active roller film feeding device, relating to the field of packaging machinery technology. The centering and correction mechanism in this structure includes a centering adjustment component, a correction adjustment assembly, and a bidirectional lead screw. The centering adjustment component is hollow, and one end of the bidirectional lead screw is inserted into the cavity of the centering adjustment component, with the centering adjustment component and the bidirectional lead screw coaxial. A connecting block is fixedly mounted on one end of the bidirectional lead screw inserted into the centering adjustment component, and the connecting block is slidably mounted within the cavity of the centering adjustment component. The correction adjustment assembly includes a correction adjustment shaft and a correction adjustment component. The correction adjustment shaft is rotatably mounted on the centering adjustment component, with one end connected to the correction adjustment component and the other end inserted into the cavity of the centering adjustment component and assembled together with the connecting block.

[0004] The aforementioned literature describes a method that integrates centering and correction mechanisms to reduce the number of centering and locking structures and correction components required for the film roll, thereby reducing the output film's dimensions, facilitating installation, and resulting in a more streamlined appearance. However, this method cannot achieve seamless splicing between film rolls during the film unwinding process, thus affecting unwinding efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a film splicing heating and automatic conveying device that can splice film between film rolls during the film feeding process, avoiding interruption of film feeding. The device has a simple and reliable structure.

[0006] To achieve the above objectives, a film splicing, heating, and automatic conveying device includes a splicing assembly, a conveying assembly, two or more material racks, a lifting assembly, and a limiting assembly. The two material racks are arranged parallel to each other on a base. The lifting assembly is hinged to the inner side of the material racks. The splicing assembly is positioned between the material racks. The conveying assembly is positioned on one side of the splicing assembly. The splicing assembly includes an upper pressing member and a lower pressing member, which form a splicing cavity. The splicing assembly can press and heat the film within the splicing cavity. The lifting assembly lifts a material roll, which is fitted with a material roll, around the hinge point with the material rack to an opening on one side of the material rack. A limiting assembly positioned above the opening limits the material roll. A guide roller is provided between the material roll and the splicing assembly.

[0007] The above structure, through the lifting component, raises the material roll shaft with the sleeve attached to it to the opening of the material rack plate. Then, the limiting component prevents the material roll shaft from detaching from the opening of the material rack plate. The film then passes through the splicing component after passing around the guide roller. When splicing is not required, the splicing component does not move the film, so the film is continuously output under the drive of the conveying component. When the film on the roll is about to be conveyed out, the conveying component stops working when the film passes through the splicing component, so that the film stays on the splicing component. Then, the lifting component raises the material roll shaft with another material roll attached to it to the material rack plate. After being limited, the film of the other material roll can pass around the guide roller and enter the splicing component, so that the film on the other material roll overlaps with the film of the other material roll on the splicing component. The splicing component can then heat and fuse the overlapped film to form a whole. After cooling, the splicing component stops working, and the conveying component continues to drive to achieve uninterrupted conveying of the film.

[0008] Furthermore, the conveying assembly is disposed on one side of the splicing assembly, a first guide roller assembly is provided between the splicing assembly and the conveying assembly, and a second guide roller assembly is provided on one side of the conveying assembly.

[0009] The above setup, after passing through the splicing assembly, sequentially bypasses the first guide roller group, the conveying assembly, and the second guide roller group, thus guiding the film between the conveying assembly and the splicing assembly.

[0010] Furthermore, the splicing assembly includes an upper pressing component, a lower pressing component, a protective cover, and two driving components. A slide rail is fixedly provided on the material rack plate along the length of the material rack plate. The driving component is fixedly connected to a slider fitted on the slide rail through a pad. The slider is slidably connected to the slide rail. Limiting blocks are provided at both ends of the slide rail. The two ends of the top of the upper pressing component are fixedly connected to the output ends of the two driving components through a connecting block. The two ends of the bottom of the lower pressing component are connected to the inner sides of the two material rack plates through a connecting block.

[0011] With the above settings, by moving slider one, the entire splicing assembly can be moved along the length of the material rack plate, adjusting the position of the splicing assembly and the material film so that the material film falls exactly on the top of the lower pressing part of the splicing assembly. When the material film to be spliced ​​is stacked on the top of the lower pressing part of the splicing assembly, the upper pressing part can be moved up and down by drive component one, so that the bottom of the upper pressing part abuts against the top of the lower pressing part, and the stacked material film is squeezed.

[0012] Furthermore, heating tubes are provided on the side of the upper pressing member near the bottom and the side of the lower pressing member near the top, respectively. The heating tubes are arranged along the length of the upper and lower pressing members, and a protective cover is provided above the upper pressing member.

[0013] The above setup allows the heating element to heat the film that is pressed between the upper and lower pressing components, thereby causing the film between the upper and lower pressing components to fuse together at a high temperature, achieving splicing. The protective cover can prevent workers from accidentally touching the heated upper pressing component.

[0014] Furthermore, the conveying assembly includes a second driving component, a roller shaft, and a roller. The second driving component is connected to one side of the material rack plate via a mounting base, and the output end of the second driving component is fixedly connected to the roller shaft on which the roller is sleeved.

[0015] The above setup enables the drive component two to rotate the roller, which in turn causes the film wrapped around the roller to roll, providing power for conveying the film.

[0016] Furthermore, the lifting assembly includes a connecting shaft, two or more lifting rods, and a lifting drive component. One end of the lifting rod is fixedly sleeved on both ends of the connecting shaft, and both ends of the connecting shaft are respectively hinged to the material rack plate. The output end of the lifting drive component is hinged to the other end of the lifting rod.

[0017] The above configuration allows the lifting rod to rotate and lift around the hinge between the connecting shaft and the material rack plate via the lifting drive component, thereby lifting the material roll placed on the lifting rod to the opening of the material rack plate and placing the film roll on the material rack plate.

[0018] Furthermore, the limiting assembly includes a fixed seat, a rotating rod, and a limiting rod. The fixed seat is fixedly connected above the opening. One end of the rotating rod is hinged to the fixed seat, the other end of the rotating rod is hinged to one end of the connecting rod, the other end of the connecting rod is hinged to one end of the limiting rod, and the other end of the limiting rod passes through the top of the opening and is embedded in the opening.

[0019] The above setup allows the rotating rod to rotate around the fixed base, which in turn drives the limiting rod to move vertically, thus limiting the material roll inside the opening.

[0020] Furthermore, the guide roller assembly includes guide roller one and guide roller two, both of which are disposed between the material rack plates, with guide roller two being offset below guide roller one.

[0021] The above setup, with the staggered guide roller 2, allows the film to first pass around the guide roller 2 and then around the roller, facilitating the tensioning effect of the film passing through the splicing assembly via the guide roller 2.

[0022] Furthermore, the second guide roller assembly includes a third guide roller, a fourth guide roller, a fifth guide roller, and a sixth guide roller. The third guide roller is offset below the second guide roller, while the fourth, fifth, and sixth guide rollers are positioned on one side of the third guide roller.

[0023] The above settings can further tension the output film through the second guide roller assembly. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 7As shown, a film splicing, heating, and automatic conveying device includes a splicing assembly, a conveying assembly, two or more material racks a1, a lifting assembly, and a limiting assembly. Two material racks a1 are arranged parallel to each other on a base a2. A connecting column a3 is provided between the bottoms of the two material racks a1, and the two material racks a1 are connected by the connecting column a3 to form a single unit, which is then connected to the base a2. The lifting assembly is hinged to the inner side of the material racks a1. The lifting assembly includes a connecting shaft a4, two or more lifting rods a5, and a lifting drive component a6. In this embodiment, both the lifting rods a5 and the lifting drive component a6 are two in number. The two lifting rods a5 are respectively located at both ends of the connecting shaft a4, and the two lifting rods a5 are positioned between each other. A support column a7 is also provided, located on one side of the connecting shaft a4. One end of the lifting rod a5 is sleeved on the connecting shaft a4, and both ends of the connecting shaft a4 are hinged to the material rack plate a1. The output end of the lifting drive a6 is hinged to the other end of the lifting rod a5. Thus, the lifting rod a5 is driven by the lifting drive a6 to rotate and lift around the hinge point between the connecting shaft a4 and the material rack plate a1. In this way, during the lifting process, the support column a7 can restrict the rotation of the material roll a8 around the material roll shaft a9, thereby stably lifting the material roll shaft a9 placed on the lifting rod a5 to the opening of the material rack plate a1, and placing the material roll a8 on the material rack plate a1. In this embodiment, the lifting drive a6 is a drive motor.

[0033] The splicing assembly is disposed between the material rack plates a1. The splicing assembly includes an upper pressing component a10, a lower pressing component a11, a protective cover a12, and two driving components a13. The upper pressing component and the lower pressing component form a splicing cavity. A slide rail a14 is fixedly provided on the material rack plate a1 along the length direction of the material rack plate a1. The driving component a13 is fixedly connected to the slider a16 sleeved on the slide rail a14 through a pad a15. The slider a16 is slidably connected to the slide rail a14. Limiting devices are provided at both ends of the slide rail a14. Block a17, the top two ends of the upper pressing component a10 are fixedly connected to the output ends of the two driving components a13 respectively via connecting block a18, the bottom two ends of the lower pressing component a11 are connected to the inner sides of the two material rack plates a1 respectively via connecting block a19, heating tubes a20 are provided on the side of the upper pressing component a10 near the bottom of the upper pressing component a10 and the side of the lower pressing component a11 near the top of the lower pressing component a11, the heating tubes a20 are arranged along the length direction of the upper pressing component a10 and the lower pressing component a11, and the protective cover a. 12 is positioned above the upper pressure member a10. This allows the entire splicing assembly to move along the length of the material rack plate a1 by moving the slider a16, adjusting the position of the splicing assembly and the material film so that the material film falls precisely on top of the lower pressure member a11. When the material films to be spliced ​​overlap the top of the lower pressure member a11, the upper pressure member a10 can be moved up and down by the drive member a13, causing the bottom of the upper pressure member a10 to abut against the top of the lower pressure member a11, thus achieving overlapping. The combined film is extruded, and after extrusion, the film, pressed between the upper and lower pressing members a10 and a11, is heated by the heating tube a20. This causes the film between the upper and lower pressing members a10 and a11 to fuse together at a high temperature, achieving splicing. The protective cover a12 prevents workers from accidentally touching the heated upper pressing member a10. In this embodiment, the protective cover a12 has heat dissipation holes on both sides to facilitate heat diffusion and accelerate cooling after fusion. The heating tube a20 is connected to an external power source.

[0034] The conveying assembly is located on one side of the splicing assembly. The conveying assembly includes a second drive component a21, a roller shaft a22, and a roller a23. The second drive component a21 is connected to one side of the material rack plate a1 via a mounting base a24. The second drive component a21 is mounted on the mounting base a24. The output end of the second drive component a21 is fixedly connected to the roller shaft a22, which passes through the material rack plate a1. The roller a23 is sleeved on the roller shaft a22. Thus, the second drive component a21 drives the roller a23 to rotate, thereby causing the material film wrapped around the roller a23 to roll, providing power for conveying the material film. The second drive component a21 is a drive motor.

[0035] A guide roller group one is provided between the splicing assembly and the conveying assembly. The guide roller group one includes guide roller one a25 and guide roller two a26. Guide roller one a25 and guide roller two a26 are both arranged between the material rack plates a1. Guide roller two a26 is staggered and arranged below guide roller one a25. In this embodiment, the cross-sectional area of ​​guide roller one a25 and guide roller two a25 is smaller than the cross-sectional area of ​​roller a23, which facilitates roller a23 to drive the material film wound on roller a23 to rotate. During the output of material film, the staggered guide roller two a26 allows the material film to first pass around guide roller two a26 and then around roller a23, which facilitates the tensioning effect of guide roller two a26 on the material film a35 passing through the splicing assembly.

[0036] One side of the conveying assembly is provided with a second guide roller assembly, which includes a third guide roller (a27), a fourth guide roller (a28), a fifth guide roller (a29), and a sixth guide roller (a30). Between the two material rack plates (a1), shafts matching the third guide roller (a27), fourth guide roller (a28), fifth guide roller (a29), and sixth guide roller (a30) are respectively fitted onto the guide rollers. Connected to the corresponding shaft, guide roller 3a27 is offset below guide roller 2a26, and guide rollers 4a28, 5a29 and 6a30 are set on one side of guide roller 3a27. This allows the film to be output as guide rollers 3a27, 4a28, 5a29 and 6a30 rotate. At the same time, guide roller group 2 further tensions the output film.

[0037] The lifting assembly lifts the material roll shaft, which is fitted with the material roll, around the hinge point with the material rack plate to the opening on one side of the material rack plate. The limiting assembly above the opening limits the material roll shaft. A guide roller a31 is provided between the material roll and the splicing assembly. In this embodiment, the height of the guide roller a31 matches the height of the pressing member a11.

[0038] In this embodiment, centering devices are provided on both sides of the material roll a8. The centering devices are respectively set on the material rack plate a1. The centering device includes a driving component a32, a connecting plate a33, and a push block a34. The driving component a32 is fixedly connected to the material rack plate a1. The output end of the driving component a32 is fixedly connected to one end of the connecting plate a33. The other end of the connecting plate a33 is detachably connected to the push block a34. In this way, after the material roll a8 is placed on the material rack plate a1, the centering adjustment of the material roll a8 can be performed by the centering devices located on both sides of the material roll a8.

[0039] The limiting assembly includes a fixed base a36, a rotating rod a37, and a limiting rod a38. The fixed base a36 is fixedly connected above the opening. One end of the rotating rod a37 is hinged to the fixed base a36, and the other end of the rotating rod a37 is hinged to one end of the connecting rod a37. The other end of the connecting rod a37 is hinged to one end of the limiting rod a38. The other end of the limiting rod a38 passes through the top of the opening and is embedded in the opening. Thus, by rotating the rotating rod a37 around the fixed base a36, the limiting rod a38 can be moved in the vertical direction to limit the material roll a9 inside the opening.

[0040] The working principle of this utility model is as follows: When splicing is not required, the splicing component does not operate on the film. After passing through the splicing component, the film passes sequentially around the first guide roller group, the conveying component, and the second guide roller group. Under the drive of the conveying component, the film is continuously output. When the film on the roll a8 is about to be completely conveyed, the conveying component stops working when the film passes through the splicing component, causing the film to stop on the lower pressing part a11 of the splicing component. The conveyed roll shaft is moved out of the opening, and then the lifting component lifts the roll shaft a9 with another roll attached to it to the material rack plate a1. After being limited, the film of the other roll can pass around the guide roller a31 and enter the splicing component, so that the film on the roll and the film of the other roll are superimposed on the splicing component. The splicing component can heat and fuse the superimposed film to form a whole. After cooling, the splicing component stops operating, and the conveying component continues to drive to achieve uninterrupted conveying of the film.
